Description

Automotive seat inspection system and method

[0001] The present invention relates to a system and method for quality inspection of automobile seats, and more particularly, to an intelligent inspection system and a control method thereof, which can automatically inspect whether various components included in automobile seats, such as ventilation functions, recliner operation status, belt notification sensors, electrical components, and seat detection sensors, are functioning normally, and can determine and record the results based on data. The present invention is configured to detect in advance whether there is a malfunction in a seat in a vehicle assembly line or quality control process, and, if necessary, control to sort or rework defective seats. In particular, the present invention can implement a high-precision inspection function by utilizing a multi-joint robot, sensor fusion technology, vision recognition, load cells, thermal imaging cameras, AI-based judgment algorithms, and the like. In addition, the present invention relates to an inspection technology field that enables flexible inspection item setting and inspection flow control so as to respond to the seat structures and functional specifications of various automobile models as well as a single automobile model, and also enables automatic storage of inspection history and quality tracing functions through linkage with an MES or other production management system.

[0002] The automotive industry is increasingly demanding quality standards for vehicle seats as they evolve toward sophistication, electrification, and multi-functionality. Consequently, precise inspection technology for seat components is becoming increasingly essential. In particular, ventilation, recliner operation, seat belt reminders, electrical modules, and seating responses are not only directly linked to occupant safety but also key factors influencing the vehicle's emotional quality. Therefore, the need for sophisticated inspection systems capable of precisely verifying their proper functioning is growing.

[0003] Conventional seat inspection processes have largely relied on manual labor or simple automated equipment. For example, ventilation function verification involved manual airflow checks or fixed sensor locations. Recliner fastening and switch operation inspections were also typically performed manually, relying on visual inspection. However, these methods had limitations in terms of precision and reliability, and inspection quality frequently varied depending on operator skill. Furthermore, despite the fact that inspection items and methods vary depending on vehicle model, specifications, and seat configuration, existing equipment had structural limitations that prevented flexible response.

[0004] In particular, seats are structurally complex, with sensors, motors, vents, heating elements, and electronic control units embedded in various areas. Therefore, simple visual inspections alone can be insufficient to detect functional abnormalities early on. Furthermore, minor errors, foreign objects, and fastening defects that may arise during assembly and production often lead to consumer dissatisfaction or vehicle recalls after delivery. To prevent this, independent yet integrated precision inspections of each component are necessary.

[0005] For example, seat belt reminder systems require simulations of actual occupant conditions to verify the responses of individual sensors against a virtual occupant load. Ventilation functions require measuring airflow and speed across the seat cushion and backrest. Furthermore, recliner fastening requires automatic analysis of nut fastening depth, torque, and insertion position. Switches require vision-based positioning and AI-based alignment. Furthermore, data collection and precise analysis are required across diverse areas, including electrical characteristics, thermal imaging-based anomaly detection, gap and pressure measurement, and seat vibration noise detection.

[0006] Therefore, automotive manufacturing sites require advanced inspection platforms that can flexibly handle multi-functional, multi-vehicle inspections by combining various sensors, robots, vision systems, and AI algorithms. Furthermore, there is a pressing need for systems that go beyond conventional single-purpose equipment to comprehensively inspect the entire seat configuration and even perform automatic feedback and correction functions. Reflecting this need, the present invention proposes a novel inspection system and method capable of automated measurement, judgment, and control of various inspection items targeting vehicle seats.

[0007] Automotive seats are components directly linked to key vehicle functions, including passenger safety, comfort, and operability. Recently, they have been equipped with a variety of features, including ventilation modules, recliners, heaters, seating sensors, and electric control devices. However, this increased functionality has led to an exponential increase in inspection items, necessitating more sophisticated inspection methods to precisely determine whether each function is functioning properly.

[0008] Conventional sheet inspection processes primarily rely on visual inspection, simple testers, and fixed-position manual sensors, with inspectors inspecting each sheet individually. This approach limits inspection speed and accuracy, and can lead to quality inconsistencies due to human judgment or inter-worker deviations. Furthermore, despite the need for different inspection items and methods for different vehicle models and seat configurations, existing inspection equipment struggles to flexibly adapt to anything outside of a standardized process, hindering production flexibility and quality control.

[0009] For example, seat belt reminder systems must simulate the actual seating position of a passenger to check for load response. However, existing methods cannot precisely control the balance and location of the load, resulting in a high false positive rate and low defect detection accuracy. In the case of ventilation function inspection, it was difficult to quantitatively measure the proper distribution of air to the seat cushion and backrest by zone, making precise quality assurance impossible. Recliner and seat operation functions also had limitations in that they could not be inspected automatically for detailed items such as nut tightening depth, torque value, and image analysis of the tightening status. Furthermore, existing technologies could not comprehensively address various inspection items, such as current measurement of the seat's electrical components, heat uniformity determination, and noise and vibration analysis, within a single system.

[0010] Accordingly, the purpose of the present invention is to eliminate errors occurring in existing manual inspection processes and maximize inspection efficiency by precisely measuring various inspection items targeting automobile seats and enabling automated judgment and recording of these items. Furthermore, the present invention provides an inspection system and method that can flexibly respond to differences in vehicle models and seat specifications, and integrate multiple inspection technologies (vision, sensors, robots, AI, etc.) to simultaneously perform high-precision judgment and history-based quality management.

[0011] In order to solve the above-mentioned problem, the present invention provides an inspection system and method configured to precisely inspect various functional items of an automobile seat.

[0012] The inspection system according to the present invention comprises an inspection unit for determining whether there is a functional abnormality in a component of an automobile seat, and a control unit for performing an abnormality determination based on data obtained from the inspection unit. The inspection unit is configured to apply operational stimuli to various items, such as ventilation function, headrest operation, recliner fastening status, seat belt warning sensor response, seating response, noise, electrical characteristics, and gaps between structures, and collect the responses using sensors.

[0013] The above inspection unit can be combined with a multi-joint robot as needed to perform precise trajectory movement according to the location of the inspection target, and can perform collision prevention and position error correction functions by incorporating a force sensor or position sensor. The motion stimulus can be implemented in various forms, such as mechanical pressure, tension, rotation, or electrical signal application, and the response to each stimulus is measured by various sensors, such as a load cell, air volume sensor, distance sensor, vision camera, thermal imaging camera, microphone, and current sensor.

[0014] The control unit collects this sensor data, compares it to predefined reference values, and determines failures for items exceeding the tolerance range. Furthermore, a machine learning-based anomaly detection algorithm may be included to integrate multiple sensor data to detect abnormal response patterns and perform failure prediction based on these patterns.

[0015] According to one embodiment of the present invention, when inspection items vary depending on the type of sheet, the sheet is automatically identified through an RFID tag or vision-based shape recognition, and an inspection scenario corresponding to the identified sheet information is selected to automatically set inspection items, stimulus conditions, reference values, etc.

[0016] In addition, in the case of seat belt notification sensor inspection, multiple independently controllable pressurization units including fluid expansion modules are applied, enabling local pressurization that precisely corresponds to the sensor position, and enabling more precise determination by individually analyzing the response signal.

[0017] Recliner fastening status inspection detects fastening depth, fastening deviation, or the use of dissimilar parts through vision-based image analysis, and noise analysis collects abnormal noise generated during operation through multiple microphone arrays and is configured to trace the location of the abnormality through triangulation and frequency analysis techniques.

[0018] Additionally, the inspection method according to the present invention comprises a step of applying a stimulus to a sheet component to induce a motion state, collecting response data through multiple sensors, and comparing it with a reference value to determine whether it is normal. At this time, an artificial intelligence algorithm is applied to interpret the data sequence and detect abnormal patterns. The inspection results are transmitted to an MES or external server and stored as a quality history.

[0019] In this way, the present invention can provide a flexible and intelligent inspection system and method that can realize high-precision, high-reliability automatic inspection of automobile seats having various functions, while actively responding to vehicle type diversity and changes in production conditions.

[0020] The inspection system and method according to the present invention enable high-precision and highly reliable automatic inspection of various functional elements built into automobile seats, such as ventilation devices, headrest actuators, recliner fasteners, belt notification sensors, seating response detectors, electrical modules, gaps between structures, and operating noise. Minor abnormalities or assembly deviations, which were difficult to identify through conventional manual or simple repetitive inspection methods, can be quantitatively analyzed in real time using a multi-joint robot, various precision sensors, and an artificial intelligence-based judgment algorithm, thereby significantly improving the consistency and reproducibility of inspection quality.

[0021] Furthermore, the system can automatically identify the vehicle type, specifications, and structural differences of the inspection target and dynamically set appropriate inspection items and conditions, enabling flexible response even in multi-vehicle production environments. Specifically, seat identification using RFID tags or vision-based shape recognition, along with modularized inspection units and scenario-based control, enhance the versatility and expandability of the inspection equipment. Furthermore, the system can be adapted with minimal adjustments even when new vehicle types or features are added.

[0022] Additionally, independent or integrated inspections are possible for each item, including seat belt reminder sensors, ventilation functions, recliner fastening status, electrical characteristics, and operating noise, enabling both reduced inspection time and early defect detection. Inspection results are linked to the Manufacturing Execution System (MES) and stored in real time, and can also be used for statistical analysis of defect data and quality tracking.

[0023] Therefore, the present invention provides a precise and flexible inspection environment for various functional elements included in automobile seats, and can greatly contribute to securing quality stability and improving production efficiency by increasing the level of inspection automation.

These embodiments are described in sufficient detail to enable those skilled in the art to practice the present invention. It should be understood that the various embodiments of the present invention, while different from each other, are not necessarily mutually exclusive.

Furthermore, it should be understood that the positions or arrangements of individual components within each disclosed embodiment may be modified without departing from the spirit and scope of the present invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly described. Like reference numerals in the drawings designate the same or similar functionality throughout the several aspects.

[0213] The present invention relates to a high-precision inspection robot for automobile seats, a control method thereof, and a system including the same, and is configured to perform advanced automatic inspections on various items such as seat ventilation, headrest operation, recliner fastening status, belt notification sensor, electrical module, seat pressure response, operating force, and gap distance. In particular, the present invention encompasses a number of embodiments, each of which forms an independently operable technical unit, while being designed to be interconnected and capable of complex operation within a single integrated platform called a seat inspection system.

[0214] The present invention goes beyond simple functional anomaly detection and includes an intelligent inspection system capable of precision inspection based on a multi-joint robot that can operate flexibly even in confined inspection spaces, structural judgment using vision and distance sensors, AI-based anomaly prediction, real-time trajectory correction, and automatic baseline updates. The various sensor data collected during inspection is interpreted in real time by a judgment algorithm, enabling automatic adaptive control based on sheet shape, specifications, positional errors, or assembly deviations. This significantly contributes to ensuring high-precision quality as well as enhancing production flexibility and inspection reliability.

[0215] Each embodiment is optimized for the specific component characteristics, operating method, and inspection criteria of the automotive seat being inspected. The robot's operating unit, inspection unit, and control algorithm are modularized to form an integrated platform. This allows for a common hardware configuration and software adjustments to address a wide range of seat models and optional specifications, extending beyond a single vehicle model.

[0216] For example, the present invention is configured to precisely inspect items directly related to the main functions and safety of the seat, such as a system for measuring the air volume by ventilation zone of the seat, a system for detecting load and position errors when the headrest is raised / lowered, a system for determining whether a seat belt notification sensor is operating through actual seating pressure, a system for precisely analyzing the recliner fastening status based on torque and vision, a system for inspecting the operation of switches through AI-based image reading, a B-FORM system for simulating seating response and pressurization state, a system for detecting abnormal noise generated when the seat is operated through precision microphone and frequency analysis, a system for diagnosing the normal operation of the electrical circuit through real-time current and thermal image data, and a gap sensing system for measuring the pop-up strength of the folding seat and the gap between structures.

[0217] These inspection systems can be configured independently for each item, or they can be operated as integrated inspection lines or complex systems with multiple inspection modules linked together based on a common control unit, robot, and interface. Furthermore, the AI-based judgment algorithm is applied across various inspection items, and it is configured to learn defect occurrence patterns through repeatedly accumulated sensor data, enabling expansion into failure prediction capabilities.

[0218] Furthermore, the present invention can be directly applied to product groups having similar structures, such as railway vehicle seats, aircraft seats, electric mobility seats, and medical seating devices, or can be utilized by modifying some modules. It was designed with expandability in mind so that it can continuously accommodate expansion of inspection items and technological advancements in accordance with the trend of advancement in high-function seat structures in the future.

[0219] The present invention integrates various technologies, including a multi-joint collaborative robot, precision position control technology, distance and vision sensor fusion, pressure control technology, AI-based recognition algorithms, and a real-time trajectory feedback and correction system. Each technology component can be independently or combined to accommodate a variety of inspection scenarios. Therefore, those skilled in the art can apply this to a single system or to multiple systems in a connected manner, and such transformable forms are also included within the scope of the present invention.

[0220] Hereinafter, for each embodiment of the present invention, the specific configuration, inspection target and method, robot and sensor arrangement structure, control flow, judgment algorithm, etc. are described in detail with reference to the drawings, and technical connectivity and expandability are also presented.

[0308] Referring to FIG. 16, the individual pressurized portion (240) includes a fluid supply tank (241), a tube housing (242), and an expansion tube (243).

[0309] The fluid supply tank (241) supplies fluid, which is a fluid substance such as water, oil, or air, to the tube housing (242) and the expansion tube (243), or recovers the fluid that was supplied to the tube housing (242) and the expansion tube (243).

[0310] The tube housing (242) is installed on the lower side of the fluid supply tank (241) and supplies fluid from the fluid supply tank (241) or transfers the supplied fluid back to the fluid supply tank (241).

[0311] The expansion tube (243) is formed of an elastic material that can expand or contract, such as rubber, and is installed while sealing the lower side of the tube housing (242). As fluid is supplied to the tube housing (242), it expands and pressurizes the seat (1) belt notification sensor, and as fluid is returned from the tube housing (242) to the fluid supply tank (241), it contracts.

[0312] The individual pressurizing units (240) having the configuration described above can not only individually drive expansion or contraction, but also precisely control the volume of expansion or contraction, thereby pressurizing the seat belt notification sensor (3) installed in the B-FORM, thereby implementing a simulation of an actual passenger sitting on a vehicle seat and pressing it, and can precisely read whether the seat belt notification sensor (3) is defective.

[0313] FIGS. 17 to 19 are drawings showing an embodiment of the B-FORM of FIG. 11.

[0314] Referring to FIGS. 17 to 19, a B-FORM (220) according to one embodiment includes a base frame (221), a sideform (222), an end plate (223), an actuator (224), a pocket support wing (225), a plurality of first air pockets (226), and a plurality of second air pockets (227).

[0315] The base frame (221) is installed at the bottom of the lifting slider (210) and moves up and down.

[0316] The side form (222) is made of a material that can expand or contract (e.g., Styrofoam or sponge) and is installed on one side and the other side of the base frame (221), respectively, and its shape is supported by the end plate (223), the actuator (224), and the pocket support wing (225).

[0317] The end plates (223) are installed at each end of the side form (222) and are moved away from or closer to the base frame (221) by an actuator (224) to change the shape of the side form (222) in response to the size of the passenger's buttocks.

[0318] The actuator (224) is installed on one side and the other side of the base frame (221), respectively, to support the end plate (223), and is driven to extend or contract to move the end plate (223) toward or away from the base frame (221), thereby extending or contracting the side form (222).

[0319] The pocket support wings (225) are formed in a flat shape and are respectively mounted in wing mounting grooves formed at the lower ends of one side and the other side of the base frame (221), and each end exposed from the wing mounting groove is installed in the end plate (223), and moves together as the end plate (223) moves.

[0320] A plurality of first air pockets (226) are installed in a row along the lower side of the base frame (221) and are individually expanded or contracted.

[0321] A plurality of second air pockets (227) are installed in a row along the lower side of the pocket support wing (225) and are individually expanded or contracted.

[0322] Here, the first air pocket (226) and the second air pocket (227) have the same configuration as the individual pressurizing portion (240) described above in FIG. 16 and are capable of expansion and contraction, and their description will be omitted to avoid duplication of explanation.

[0323] In one embodiment, the system control panel (400) can drive the actuator (224) to adjust the width of the sideform (222) in response to the manufacturer of the sheet (1) being inspected.

[0324] In one embodiment, the system control panel (400) can individually expand or contract each of the first air pocket (226) and the second air pocket (227) to vary the curvature of the bottom surface of the B-FORM (220) in response to the manufacturer of the sheet (1) being the test object.

[0325] According to one embodiment of the B-FORM (220) having the configuration described above, not only can the surface curvature be varied by using the first air pocket (226) and the second air pocket (227) that can be individually expanded and contracted, but also the entire area or width can be varied in response to the size of the passenger's buttocks, thereby enabling more precise sensor inspection.

[0326] FIG. 20 and FIG. 21 are drawings schematically illustrating the configuration of a recliner automatic fastening system according to one embodiment of the present invention.

[0327] Referring to FIGS. 20 and 21, a recliner automatic fastening system (10) according to one embodiment of the present invention includes a multi-joint robot (100), a vision confirmation unit (200), a nut fastening unit (300), and a fastening confirmation unit (400).

[0328] The multi-joint robot (100) is installed along the conveyor line (2) of the automobile seat (1) and is a multi-joint robot device having at least one observation device to precisely move the nut fastening part (300).

[0329] The vision confirmation unit (200) is installed on the multi-joint robot (100) or at least one unit along the conveyor line (2) of the automobile seat (1), and uses 2D vision sensing to confirm the position of the nut (N) fastened to the automobile seat (1), and then notifies the multi-joint robot (100), and vision senses the nut (N) that has been fastened.

[0330] In one embodiment, the vision confirmation unit (200) can sense the nut (N) fastening process of the nut fastening unit (300) through 2D vision and transmit it to the fastening confirmation unit (400) in real time.

[0331] The nut fastening unit (300) is a nut (N) fastening device that allows for precise torque control and sensing at the same time, is installed on a multi-joint robot (100), and fastens the nut (N) when moved to the position of the nut (N) that has been pre-fastened by the multi-joint robot (100).

[0332] In one embodiment, the nut fastening unit (300) can fasten the nut (N) until a preset torque value (i.e., a torque value at which fastening of the nut (N) is completed, etc.) is reached by the driving control of the fastening confirmation unit (400).

[0333] The fastening confirmation unit (400) controls the operation of devices such as the multi-joint robot (100), the vision confirmation unit (200), and the nut fastening unit (300), and uses the sensing data acquired by vision sensing the nut (N) that has been fastened and received from the vision confirmation unit (200) to confirm whether the nut (N) is normally fastened.

[0334] In one embodiment, the fastening confirmation unit (400) can determine whether the nut (N) is normally fastened by checking the exposed length of the protruding end of the bolt (B) that has been fastened by the nut fastening unit (300) using sensing data received from the vision confirmation unit (200) and then inferring the final fastening position of the nut (N).

[0335] In one embodiment, the fastening confirmation unit (400) uses sensing data received in real time from the vision confirmation unit (200) to confirm whether the joints of the multi-joint robot (100) are twisted or the car seat (1) is warped during the fastening of the nut (N), and if the twisting of the joints of the multi-joint robot (100) or the warping of the car seat (1) is confirmed, the fastening of the nut fastening unit (300) can be stopped, 2D vision sensing by the vision confirmation unit (200) can be re-executed, and then the fastening by the nut fastening unit (300) can be re-executed.

[0336] In one embodiment, the fastening confirmation unit (400) can confirm whether the nut (N) is normally fastened based on the fastening torque value of the nut (N) and the position of the multi-joint robot (100).

[0337] In one embodiment, the fastening confirmation unit (400) can prevent fastening of different types of nuts (N) by identifying the type of nut (N) using the insertion depth of the nut (N) detected through 2D vision sensing from the side of the nut (N) using the vision confirmation unit (200).

[0338] In one embodiment, the fastening confirmation unit (400) can identify the type of nut (N) by using the shape of the fastened nut (N) detected through 2D vision sensing using the vision confirmation unit (200).

[0339] The recliner automatic fastening system (10) according to one embodiment of the present invention having the configuration described above applies 2D vision to a robot to check the position of a nut (N) fastened to a seat, then fastens the nut (N), and uses a torque value to check whether the nut (N) is fastened, thereby minimizing human error, saving manpower, maximizing productivity and efficiency, and efficiently operating the production process.

[0340] Fig. 22 is a flowchart illustrating a recliner automatic fastening method according to one embodiment of the present invention.

[0341] Referring to Fig. 22, in a recliner automatic fastening method according to one embodiment of the invention, first, a nut fastening part (300) enters a position where a nut (N) is pre-fastened by a multi-joint robot (100) (S110).

[0342] In one embodiment, the nut (N) entry step (S110) may be recognized as an error (for example, as shown in FIG. 23, it is determined that a foreign substance (A) exists in the nut (N) or nut fastening part (300) or a different nut (N) as shown in FIGS. 24 to 26) if the nut fastening part (300) is entered less than or over-entered than the pre-determined entry depth (in the case of Yes in S115), and then vision re-capturing using the vision confirmation unit (200) may be performed and re-entry (S110) of the nut fastening part (300) may be attempted again.

[0343] That is, in the case where the nut fastening part (300) is under-entered by a different nut (N) having a large diameter as illustrated in FIG. 24, or the nut fastening part (300) is over-entered by a different nut (N) having a thin thickness as illustrated in FIG. 25, or the nut fastening part (300) is over-entered by a different nut (N) having a different inner diameter as illustrated in FIG. 26, by recognizing the case where the nut fastening part (300) is judged to be under-entered or over-entered as an error, the nut fastening part (300) can be re-attempted (S110) through vision re-capturing using the vision confirmation part (200) or the operator can be requested to replace the nut (N) so that precise fastening can be achieved.

[0344] In the nut (N) entry step (S110), if the nut (N) entered within the normal range (in the case of No in S115), the nut (N) that was temporarily fastened by the nut fastening part (300) is fastened to the final fastening position (S120).

[0345] In one embodiment, the fastening step (S120) measures the change in the position of the multi-joint robot (100) and the change in the torque value of the nut fastening part (300), and if the change in the torque value of the nut fastening part (300) is measured to be less than the expected change in the position of the multi-joint robot (100) until the final fastening position of the nut (N) (in the case of Yes in S125), as shown in FIG. 23, it is determined that a foreign substance (A) is present and thus the fastening is not completely completed (S140), and this is transmitted to the fastening confirmation part (400), so that the steps from the nut (N) entry step (S110) to the fastening step (S120) described above can be performed again.

[0346] When the nut fastening part (300) is completely moved to the expected position by the multi-joint robot (100) (in the case of No in S125), the fastening is completed. The fastening confirmation part (400) uses the vision confirmation part (200) to sense the nut (N) and acquire sensing data to confirm whether the nut (N) is normally fastened (S130).

[0347] A recliner automatic fastening method according to one embodiment of the invention having the configuration described above applies 2D vision to a robot to check the position of a nut (N) fastened to a seat, then fastens the nut (N), and uses a torque value to check whether the nut (N) is fastened, thereby minimizing human error, saving manpower, maximizing productivity and efficiency, and efficiently operating a production process.

[0348] Figure 27 is a schematic diagram showing an automobile seat manufacturing system according to one embodiment of the present invention.

[0349] Referring to FIG. 27, an automobile seat manufacturing system (30) according to one embodiment of the present invention may be configured to include an automobile seat manufacturing device (10) and an automobile seat inspection device (20).

[0350] As such, the components of the automobile seat manufacturing system according to one embodiment of the present invention merely represent functionally distinct elements, so two or more components may be implemented integrated with each other in an actual physical environment, or one component may be implemented separately from each other in an actual physical environment.

[0351] As described for each component, the automobile seat manufacturing device (10) can manufacture an automobile seat that can be included in an automobile part.

[0352] Here, the automobile seat is intended to maintain the optimal riding posture of the passenger in the automobile, and may include a seat cushion that supports the passenger's lower body, a seat back that supports the passenger's upper body, and a headrest that supports the passenger's head. In addition, the automobile seat may include a frame that serves as a framework, a fabric cover, a heating module, a ventilation module, and a plastic cover that covers the exterior.

[0353] First, in order to manufacture an automobile seat, an automobile seat manufacturing device (10) can manufacture a foam pad, which serves as a basis for manufacturing a seat cushion, a seat back, and a headrest, through an injection mold.

[0354] For example, a foam pad can be manufactured by using polyol and isocyanate as the main ingredients, and by mixing various other chemicals and foaming them in a casting mold at a certain temperature.

[0355] Meanwhile, during the foam pad molding process, a parting agent can be applied to the inner surface of the mold so that the raw material does not stick to the surface of the foam pad mold and can be easily removed.

[0356] In particular, an automobile seat manufacturing device (10) according to one embodiment of the present invention may be configured to include an automatic release agent spraying device (100) for automating the spraying of a release agent to prevent a molded product from being attached to the inner surface of a mold when molding a headrest of an automobile seat through a mold.

[0357] A release agent injection automation device (100) may be configured to include at least one mold corresponding to the shape of a part included in a car seat, a turn table on which at least one mold is installed and which rotates at least one installed mold around a specific point, a spray unit that sprays a release agent onto the at least one mold according to the rotation of the turn table, and a control unit that controls at least one mold, the turn table, and the spray unit.

[0358] Meanwhile, the specific structure of the heterogeneous agent injection automation device (100) according to one embodiment of the present invention will be described in detail with reference to FIG. 28 below.

[0359] In addition, the automobile seat manufacturing device (10) can insert various auxiliary materials into a mold to which a release agent has been applied, inject raw materials, and then separate the molded product from the mold after a certain period of time has elapsed. Thereafter, the automobile seat manufacturing device (10) can pass the foam pad separated from the mold to the next process by subjecting the foam pad to a crushing process to remove air pockets.

[0360] The automobile seat manufacturing device (10) can cover the outer surface of the foam pad corresponding to each of the seat cushion, seat back, and headrest, and assemble them onto a back frame. In addition, the automobile seat manufacturing device (10) can additionally assemble injection parts such as additional covers and levers onto the assembled assembly.

[0361] Finally, the automobile seat manufacturing device (10) can manufacture automobile seats by removing wrinkles from the seat cover through steam spraying, ironing, and passing the assembly through an infrared heating booth.

[0362] With the following configuration, the automobile seat inspection device (20) can perform inspections of functions, performance, stability, etc. of automobile seats manufactured from the automobile seat manufacturing device (10).

[0363] For example, the automobile seat inspection device (20) can perform inspections on electronic components included in automobile seats. For example, the electronic components included in automobile seats can include a motor for driving the seat, a heating module for heating the seat cushion and seat back, a ventilation module for blowing air into the seat cushion and seat back, etc.

[0364] In particular, an automobile seat inspection device (20) according to one embodiment of the present invention may be configured to include an electric inspection device (200) for performing an inspection on electronic components included in an automobile seat.

[0365] Specifically, the full-length inspection device (200) may be configured to include a booth in which at least one automobile seat to be inspected is placed by forming a closed space, a conveyor for moving at least one automobile seat into the booth or moving an automobile seat that has completed inspection out of the booth, an inspection unit for obtaining data generated from electronic components included in at least one automobile seat when at least one automobile seat is placed at a preset position inside the booth through the conveyor, and a control unit for controlling the booth, conveyor, and inspection unit.

[0366] Meanwhile, the specific configuration of the full-field inspection device (200) according to one embodiment of the present invention will be described in detail with reference to FIG. 29 below.

[0367] In this way, the automobile seat manufacturing system (30) according to one embodiment of the present invention can minimize manpower loss for spraying the release agent and secure the quality of the molded product by automating the spraying of the release agent to prevent the molded product from sticking to the inside of the mold when molding the automobile seat component through the mold.

[0368] In addition, the automobile seat manufacturing system (30) according to one embodiment of the present invention can secure safety and quality by inspecting the status of electronic components included in the automobile seat.

[0369] Hereinafter, the configuration of an automatic injection device (100) according to one embodiment of the present invention will be described in detail.

[0370] Fig. 28 is a top view showing the configuration of an automatic injection device for heterogeneous agents according to one embodiment of the present invention.

[0371] Referring to FIG. 28, an automatic injection device (100) according to one embodiment of the present invention may be configured to include a mold structure (110), a turn table (120), an injection unit (130), and a control unit (140).

[0372] For each component, the mold structure (110) can be configured to include a mold having an inner surface corresponding to the shape of a part included in an automobile seat.

[0373] Specifically, the mold structure (110) can be formed to be divided into a movable mold part (111) and a fixed mold part (113), and can be configured to be movably coupled to the fixed mold part (113), or to be disassembled and operated by separating the movable mold part (111) from the fixed mold part (113).

[0374] The movable mold part (111) may be arranged to face the fixed mold part (113), and may have a mold space formed therein in which a movable mold (112) for molding a molded product is arranged, and may be configured to include the movable mold (112) arranged in the mold space and having a cavity formed therein having a shape corresponding to the shape of the molded product. In addition, the movable mold part (111) may be configured to include an extrusion hole formed in the cavity to extrude the molded product molded in the cavity, and an extrusion pin inserted into the extrusion hole and operated.

[0375] The fixed mold part (113) may be configured to include a mold space in which a fixed mold (114) for molding a molded product is placed inside, and a fixed mold (114) disposed in the mold space and having a cavity having a shape corresponding to the shape of the molded product. In addition, the fixed mold part (113) may be provided with an extrusion hole formed in the cavity to extrude the molded product molded in the cavity, and an extrusion pin inserted into the extrusion hole and operated.

[0376] In addition, the mold structure (110) may be configured to include an RFID tag for location recognition. Specifically, the mold structure (110) may be configured to have an RFID tag capable of recognizing a location installed in each of the movable mold (112) of the movable mold section (111) and the fixed mold (114) of the fixed mold section (113).

[0377] In the following configuration, the turntable (120) has at least one mold structure (110) installed and can rotate the at least one installed mold structure (110) around a specific point.

[0378] Specifically, the turntable (120) can circulate a mold structure (110) to a device that performs each fixation in order to manufacture a foam pad, which is the basis of a seat cushion, a seat back, and a head rest, through an injection mold during the manufacturing process of an automobile seat.

[0379] For example, the turntable (120) can move the mold structure (110) to an automatic release agent spraying device (100) for applying a release agent to the mold structure (110) by rotation, and when the release agent spraying is completed on the mold structure (110) by the automatic release agent spraying device (100), the turntable can move the mold structure (110) to a device for inserting a mold material into the mold structure (110) by rotation, and when the mold material is inserted into the mold structure (110), the turntable can move the mold structure (110) to a device for heating the mold structure (110) to support the manufacturing of a molded product.

[0380] In the following configuration, the injection unit (130) can spray a release agent onto the inner surface of at least one mold according to the rotation of the turntable (120). Here, the mold may include the movable mold (112) and the fixed mold (114) described above.

[0381] Specifically, the injection unit (130) may be configured to include a manipulator (131), a limit switch (132), and an injection nozzle (133).

[0382] The manipulator (131) can be operated according to the rotation of the turntable (120) by including at least one joint. That is, the manipulator (131) may be an articulated manipulator that can move the injection nozzle (133) to each area of ​​the inner surface of the mold. However, it is not limited thereto, and the manipulator (131) may be a cartesian manipulator, a cylindrical manipulator, a spherical manipulator, a SCARA (Selective Compliant Assembly Robot Arm) manipulator, etc. depending on the joint structure.

[0383] A limit switch (132) is installed on one side of the manipulator (131) and can detect the position of at least one mold. For example, a micro switch, a roller lever switch, a plunger switch, a rotary switch, etc. can be applied as the limit switch (132).

[0384] Next, the injection nozzle (133) is installed at the end of the manipulator (131) to spray the release agent according to the position of the mold structure detected by the limit switch (132).

[0385] Here, a release agent can be used to prevent the molded product from bonding to the mold surface. Failure to do so can result in the molding material fusing with the mold. This release agent forms a barrier between the molded product and the mold surface, eliminating the adhesive between the molded product and the mold, preventing mold damage and facilitating the quick and easy removal of the molded product from the mold.

[0386] In addition, the injection unit (130) may be configured to include a vision sensor installed on the manipulator (131) to photograph at least one mold structure (110). In addition, the injection unit (130) may be configured to include an RFID reader capable of recognizing an RFID tag provided on the mold structure (110). In addition, the injection unit (130) may be configured to include a distance measuring sensor that measures the distance from the vision sensor to the mold.

[0387] In the following configuration, the control unit (140) can control at least one mold structure (110), a turn table (120), and an injection unit (130).

[0388] Specifically, when the mold is positioned at a preset position within the working range of the injection unit (130) by the turntable (120), the control unit (140) detects the edge of the mold through the limit switch (132), and controls the injection nozzle (133) to move in a zigzag pattern along the inner surface of the mold based on the edge detected through the manipulator (131) to spray the release agent.

[0389] At this time, the control unit (140) can control the injection nozzle (133) to move in a zigzag pattern along the inner surface of the mold based on the edge detected on the inner surface of the mold to first spray the release agent, and can control the injection nozzle (133) to move along the detected edge to second spray the release agent.

[0390] Meanwhile, in the case of a relatively complex structure depending on the shape of the inner surface of the mold, a large amount of release agent is required because the bonding area between the molded product and the mold is large, and in the case of a relatively simple structure, a small amount of release agent is required because the bonding area between the molded product and the mold is narrow.

[0391] Accordingly, the control unit (140) can recognize the shape of the inner surface of at least one mold through a vision sensor and adjust the amount of release agent sprayed for each part according to the recognized shape.

[0392] At this time, the control unit (140) accumulates and stores the injection amount of the release agent according to the recognized shape, and can determine the injection amount of the release agent for each part of the mold structure identified through artificial intelligence (AI) that has undergone machine learning in advance based on the accumulated and stored injection amount of the release agent.

[0393] That is, the control unit (140) can accumulate and store a design drawing that stores information on the amount of release agent to be sprayed for each part according to the type of mold, and can determine the amount of release agent to be sprayed for each part for a newly recognized mold through artificial intelligence that has been previously machine-learned based on the accumulated and stored design drawing.

[0394] In addition, the control unit (140) recognizes an RFID tag through an RFID reader to identify the location and type of the mold, and sets the movement path of the injection nozzle (133) based on the location and type of the identified mold, but compares the type of the identified mold with the shape of the mold recognized through a vision sensor to recognize the warpage of the mold, and can correct the set movement path according to the degree of warpage recognized.

[0395] In addition, the control unit (140) can capture a molded product injected from a mold through a vision sensor, analyze the surface of the molded product based on the captured image, and correct a preset movement path for the mold and the injection amount of a release agent based on the analysis results.

[0396] For example, the control unit (140) can determine the point where additional injection of the release agent is required or the point where the injection amount of the release agent must be increased through surface analysis of the completed molded product, and correct the movement path and the injection amount of the release agent.

[0397] In addition, the control unit (140) can generate a fused image including distance information per pixel by fusing an image of a mold captured from a vision sensor and distance information obtained from a distance measurement sensor, and generate a movement path of the injection nozzle based on the generated fused image.

[0398] At this time, the control unit (140) generates a movement path of the injection nozzle, and generates an x-axis movement path corresponding to the width of the inner surface of the mold based on the fusion image, and applies a y-axis coordinate corresponding to the depth of the inner surface of the mold to each coordinate of the x-axis movement path to generate a final movement path.

[0399] That is, the control unit (140) can accurately control the distribution of the release agent and improve the quality of the molded product by generating a movement path that takes into account the depth of the inner surface of the mold through a distance measuring sensor.

[0400] Hereinafter, the configuration of a full-length inspection device (200) according to one embodiment of the present invention will be described in detail.

[0401] Fig. 29 is a top view showing the configuration of a full-length inspection device according to one embodiment of the present invention.

[0402] Referring to FIG. 29, a battlefield inspection device (300) using image analysis according to one embodiment of the present invention may be configured to include a booth (210), a conveyor (220), an inspection unit (230), and a control unit (240).

[0403] As for each component, the booth (210) forms a closed space, and at least one automobile seat (A) to be inspected can be placed therein.

[0404] Specifically, the booth (210) forms a soundproof space through which a conveyor (220) operating along a transport path can pass, and opening / closing doors (221) can be installed on both sides along the transport direction of the automobile seat (A). Here, the opening / closing door (221) can open / close an automobile seat input port (222) formed on one side of the booth (210) and open / close an automobile seat discharge port (223) formed on the other side of the booth (210).

[0405] The conveyor (220) can move at least one car seat (A) into the booth (210) or move an inspected car seat (A) out of the booth (210). Here, various conveyors capable of moving products, such as a belt conveyor, a screw conveyor, a bucket conveyor, a roller conveyor, and a trolley conveyor, can be applied.

[0406] The inspection unit (330) can obtain data generated from electronic equipment included in at least one automobile seat (A) when at least one automobile seat (A) is placed in a preset position inside the booth (210) via the conveyor (220).

[0407] Specifically, the inspection unit (330) may be configured with at least one microphone that detects noise generated from a car seat placed inside the booth. In addition, the inspection unit (330) may be configured to include a thermal imaging camera that detects radiant heat emitted from the car seat placed inside the booth. In addition, the inspection unit (330) may measure current generated from electronic components included in the car seat (A).

[0408] In the following configuration, the control unit (340) can control the booth (210), the conveyor (220), and the inspection unit (230). Specifically, the control unit (340) can apply power to at least one motor included in the automobile seat (A), detect noise generated from the motor according to the motor's operation, and compare the detected noise with pre-stored noise data to detect defects in the automobile seat.

[0409] At this time, the control unit (340) performs triangulation using the intensity of three or more noises received by multiple microphones, estimates the relative positional relationship between the multiple microphones and the noise generation area based on the performed triangulation, and detects a defective location by reflecting the estimated relative positional relationship.

[0410] Here, the control unit (340) can separate the detected noise into frequencies by sound wave and identify multiple motors based on the separated frequencies. At this time, the control unit (340) can identify the type of defect based on the separated frequency waveform through artificial intelligence (AI) that has undergone machine learning in advance based on the type of defect according to the frequency waveform.

[0411] In addition, the control unit (340) can apply power to a ventilation module included in the automobile seat (A), detect noise generated by the operation of the ventilation module, and compare the detected noise with pre-stored noise data to detect a defect in the automobile seat.

[0412] In addition, the control unit (340) can identify a plurality of heat source points based on a thermal image captured by a thermal imaging camera, generate an RGB (Red, Green, Blue) histogram for pixels included in an area within a preset distance from each of the plurality of heat source points, and compare the RGB histograms generated from areas corresponding to each of the plurality of heat source points to detect defects in the car seat. Here, the RGB histogram is a graph showing the brightness distribution of each primary color (RGB) in the image. For example, the RGB histogram has a horizontal axis that represents the brightness level of a color, and a vertical axis that represents the number of pixels assigned to the brightness level of a color. The more pixels there are to the left, the darker and less vivid the color is expressed, and the more pixels there are to the right, the brighter and more intense the color can be expressed. In this way, the control unit (340) can detect defects by comparing the saturation and gradation state of the color of the plurality of heat source point areas, the tendency of the white balance, etc. through the RGB histogram.

[0413] Additionally, the control unit (340) can detect defects in the car seat (A) by inputting a thermal image into an artificial intelligence (AI) model implemented with a convolutional neural network (CNN).

[0414] That is, the control unit (340) changes the resolution of the thermal image to generate an image group composed of multiple two-dimensional images with different resolutions, and then inputs all the two-dimensional images included in the image group into an artificial intelligence (AI) model implemented as a convolutional neural network (CNN), and then combines multiple result values ​​output from the artificial intelligence (AI) model to detect defects in the automobile seat (A).

[0415] Here, the convolutional neural network (CNN) can have a transformer encoder-decoder structure.

[0416] The control unit (340) converts the data constituting the thermal image into a single sequence by arranging them in a row and inputs the converted vector into an encoder, applies self-attention in the encoder to convert the data positions within the sequence into a single vector in which the data positions are connected to each other, and inputs the converted vector into a decoder, and uses a loss function based on the Hungarian algorithm in the decoder to detect defects in the car seat (A).

[0417] At this time, the encoder performs a convolution operation on the input feature map to generate an output feature map, and by reflecting a learnable offset in the size of the convolution filter, which is the area where features are extracted, the encoder can extract features from a grid area wider than the size of the convolution filter. In addition, the encoder can use the attention key as an offset when performing self-attention.

[0418] Hereinafter, with reference to FIG. 30, the injection process of the injection automation device for the injection of the injection agent will be described.

[0419] Figure 30 is an exemplary diagram for explaining a disintegrant injection process of an automated disintegrant injection device according to one embodiment of the present invention.

[0420] Referring to FIG. 30, when the mold is positioned at a preset position within the working range of the injection unit by the turn table, the control unit (140) detects the edge of the mold through a limit switch, and controls the injection nozzle to move in a zigzag pattern along the inner surface of the mold based on the edge detected through the manipulator and spray the release agent.

[0421] At this time, the control unit (140) first injects the release agent (1) while the injection nozzle moves in a zigzag pattern on the inner side of the mold based on the edge detected on the inner side of the mold. st spray) and the release agent is sprayed secondarily (2) while the injection nozzle moves along the detected edge. nd It can be controlled to spray.

[0422] Meanwhile, in the case of a relatively complex structure depending on the shape of the inner surface of the mold, a large amount of release agent is required because the bonding area between the molded product and the mold is large, and in the case of a relatively simple structure, a small amount of release agent is required because the bonding area between the molded product and the mold is narrow.

[0423] Accordingly, the control unit (140) can recognize the shape of the inner surface of at least one mold through a vision sensor and adjust the amount of release agent sprayed for each part according to the recognized shape.

[0424] Below, with reference to Fig. 31, the process of detecting defects using an artificial intelligence model is described.

[0425] Figure 31 is an exemplary diagram for explaining the structure of an artificial intelligence (AI) model according to one embodiment of the present invention.

[0426] As illustrated in Fig. 31, the control unit (340) can input a thermal image into an artificial intelligence (AI) model implemented as a convolutional neural network (CNN). Here, the convolutional neural network (CNN) can have a transformer encoder-decoder structure.

[0427] More specifically, the control unit (340) can convert the data constituting the two-dimensional image into a single sequence by arranging them in a row and inputting the sequence into the encoder. The anomaly detection unit (330) can apply self-attention in the encoder to convert the data positions within the sequence into a single vector in which they are connected to each other, and then input the converted vector into the decoder. The control unit (340) outputs a result value using a loss function based on the Hungarian algorithm in the decoder. In addition, the control unit (340) can input the result value output from the decoder into a feed-forward network (FFN) to detect a defect.

[0428] In addition, the encoder of a convolutional neural network (CNN) according to one embodiment of the present invention may be modified to perform a convolution operation on an input feature map to generate an output feature map by reflecting a learnable offset in the size of a convolution filter, which is an area from which features are extracted, when performing the convolution operation. By this modification, the encoder can extract features from a grid area wider than the size of a convolution filter that is fixed.

[0429] In addition, the encoder of a convolutional neural network (CNN) according to one embodiment of the present invention can be modified to use an offset reflected in the size of a convolutional filter as an attention key when performing self-attention. By this modification, when a large object must be predicted from a two-dimensional image, a large offset is learned, and when a small object must be predicted, a small offset is learned, thereby improving the performance of a conventional convolutional neural network (CNN) that had relatively low prediction performance for small objects.

[0430] Meanwhile, the control unit (340) does not simply determine the defect of the car seat based on a single thermal image, but can determine the presence or absence of an abnormality based on multiple two-dimensional images expanded in various ways based on a single thermal image.

[0431] Figure 32 is a schematic diagram showing an automobile seat manufacturing system according to one embodiment of the present invention.

[0432] Referring to FIG. 32, an automobile seat manufacturing system (30) according to one embodiment of the present invention may be configured to include an automobile seat manufacturing device (10) and an automobile seat inspection device (20).

[0433] As such, the components of the automobile seat manufacturing system according to one embodiment of the present invention merely represent functionally distinct elements, so two or more components may be implemented integrated with each other in an actual physical environment, or one component may be implemented separately from each other in an actual physical environment.

[0434] As described for each component, the automobile seat manufacturing device (10) can manufacture an automobile seat that can be included in an automobile part.

[0435] Here, the automobile seat is intended to maintain the optimal riding posture of the passenger in the automobile, and may include a seat cushion that supports the passenger's lower body, a seat back that supports the passenger's upper body, and a headrest that supports the passenger's head. In addition, the automobile seat may include a frame that serves as a framework, a fabric cover, a heating module, a ventilation module, and a plastic cover that covers the exterior.

[0436] First, in order to manufacture an automobile seat, an automobile seat manufacturing device (10) can manufacture a foam pad, which serves as a basis for manufacturing a seat cushion, a seat back, and a headrest, through an injection mold.

[0437] For example, a foam pad can be manufactured by using polyol and isocyanate as the main ingredients, and by mixing various other chemicals and foaming them in a casting mold at a certain temperature.

[0438] Meanwhile, during the foam pad molding process, a parting agent can be applied to the inner surface of the mold so that the raw material does not stick to the surface of the foam pad mold and can be easily removed.

[0439] In particular, an automobile seat manufacturing device (10) according to one embodiment of the present invention may be configured to include an automatic release agent spraying device (100) for automating the spraying of a release agent to prevent a molded product from being attached to the inner surface of a mold when molding a headrest of an automobile seat through a mold.

[0440] A release agent injection automation device (100) may be configured to include at least one mold corresponding to the shape of a part included in a car seat, a turn table on which at least one mold is installed and which rotates at least one installed mold around a specific point, a spray unit that sprays a release agent onto the at least one mold according to the rotation of the turn table, and a control unit that controls at least one mold, the turn table, and the spray unit.

[0441] Meanwhile, the specific structure of the heterogeneous agent injection automation device (100) according to one embodiment of the present invention will be described in detail with reference to FIG. 33 below.

[0442] In addition, the automobile seat manufacturing device (10) can insert various auxiliary materials into a mold to which a release agent has been applied, inject raw materials, and then separate the molded product from the mold after a certain period of time has elapsed. Thereafter, the automobile seat manufacturing device (10) can pass the foam pad separated from the mold to the next process by subjecting the foam pad to a crushing process to remove air pockets.

[0443] The automobile seat manufacturing device (10) can cover the outer surface of the foam pad corresponding to each of the seat cushion, seat back, and headrest, and assemble them onto a back frame. In addition, the automobile seat manufacturing device (10) can additionally assemble injection parts such as additional covers and levers onto the assembled assembly.

[0444] Finally, the automobile seat manufacturing device (10) can manufacture automobile seats by removing wrinkles from the seat cover through steam spraying, ironing, and passing the assembly through an infrared heating booth.

[0445] With the following configuration, the automobile seat inspection device (20) can perform inspections of functions, performance, stability, etc. of automobile seats manufactured from the automobile seat manufacturing device (10).

[0446] For example, the automobile seat inspection device (20) can perform inspections on electronic components included in automobile seats. For example, the electronic components included in automobile seats can include a motor for driving the seat, a heating module for heating the seat cushion and seat back, a ventilation module for blowing air into the seat cushion and seat back, etc.

[0447] In particular, an automobile seat inspection device (20) according to one embodiment of the present invention may be configured to include an electric inspection device (200) for performing an inspection on electronic components included in an automobile seat.

[0448] Specifically, the full-length inspection device (200) may be configured to include a booth in which at least one automobile seat to be inspected is placed by forming a closed space, a conveyor for moving at least one automobile seat into the booth or moving an automobile seat that has completed inspection out of the booth, an inspection unit for obtaining data generated from electronic components included in at least one automobile seat when at least one automobile seat is placed at a preset position inside the booth through the conveyor, and a control unit for controlling the booth, conveyor, and inspection unit.

[0449] Meanwhile, the specific configuration of the full-field inspection device (200) according to one embodiment of the present invention will be described in detail with reference to FIG. 34 below.

[0450] In this way, the automobile seat manufacturing system (30) according to one embodiment of the present invention can minimize manpower loss for spraying the release agent and secure the quality of the molded product by automating the spraying of the release agent to prevent the molded product from sticking to the inside of the mold when molding the automobile seat component through the mold.

[0451] In addition, the automobile seat manufacturing system (30) according to one embodiment of the present invention can secure safety and quality by inspecting the status of electronic components included in the automobile seat.

[0452] Hereinafter, the configuration of an automatic injection device (100) according to one embodiment of the present invention will be described in detail.

[0453] Figure 33 is a top view showing the configuration of an automatic injection device for heterogeneous agents according to one embodiment of the present invention.

[0454] Referring to FIG. 33, an automatic injection device (100) according to one embodiment of the present invention may be configured to include a mold structure (110), a turn table (120), an injection unit (130), and a control unit (140).

[0455] For each component, the mold structure (110) can be configured to include a mold having an inner surface corresponding to the shape of a part included in an automobile seat.

[0456] Specifically, the mold structure (110) can be formed to be divided into a movable mold part (111) and a fixed mold part (113), and can be configured to be movably coupled to the fixed mold part (113), or to be disassembled and operated by separating the movable mold part (111) from the fixed mold part (113).

[0457] The movable mold part (111) may be arranged to face the fixed mold part (113), and may have a mold space formed therein in which a movable mold (112) for molding a molded product is arranged, and may be configured to include the movable mold (112) arranged in the mold space and having a cavity formed therein having a shape corresponding to the shape of the molded product. In addition, the movable mold part (111) may be configured to include an extrusion hole formed in the cavity to extrude the molded product molded in the cavity, and an extrusion pin inserted into the extrusion hole and operated.

[0458] The fixed mold part (113) may be configured to include a mold space in which a fixed mold (114) for molding a molded product is placed inside, and a fixed mold (114) disposed in the mold space and having a cavity having a shape corresponding to the shape of the molded product. In addition, the fixed mold part (113) may be provided with an extrusion hole formed in the cavity to extrude the molded product molded in the cavity, and an extrusion pin inserted into the extrusion hole and operated.

[0459] In addition, the mold structure (110) may be configured to include an RFID tag for location recognition. Specifically, the mold structure (110) may be configured to have an RFID tag capable of recognizing a location installed in each of the movable mold (112) of the movable mold section (111) and the fixed mold (114) of the fixed mold section (113).

[0460] In the following configuration, the turntable (120) has at least one mold structure (110) installed and can rotate the at least one installed mold structure (110) around a specific point.

[0461] Specifically, the turntable (120) can circulate a mold structure (110) to a device that performs each fixation in order to manufacture a foam pad, which is the basis of a seat cushion, a seat back, and a head rest, through an injection mold during the manufacturing process of an automobile seat.

[0462] For example, the turntable (120) can move the mold structure (110) to an automatic release agent spraying device (100) for applying a release agent to the mold structure (110) by rotation, and when the release agent spraying is completed on the mold structure (110) by the automatic release agent spraying device (100), the turntable can move the mold structure (110) to a device for inserting a mold material into the mold structure (110) by rotation, and when the mold material is inserted into the mold structure (110), the turntable can move the mold structure (110) to a device for heating the mold structure (110) to support the manufacturing of a molded product.

[0463] In the following configuration, the injection unit (130) can spray a release agent onto the inner surface of at least one mold according to the rotation of the turntable (120). Here, the mold may include the movable mold (112) and the fixed mold (114) described above.

[0464] Specifically, the injection unit (130) may be configured to include a manipulator (131), a limit switch (132), and an injection nozzle (133).

[0465] The manipulator (131) can be operated according to the rotation of the turntable (120) by including at least one joint. That is, the manipulator (131) may be an articulated manipulator that can move the injection nozzle (133) to each area of ​​the inner surface of the mold. However, it is not limited thereto, and the manipulator (131) may be a cartesian manipulator, a cylindrical manipulator, a spherical manipulator, a SCARA (Selective Compliant Assembly Robot Arm) manipulator, etc. depending on the joint structure.

[0466] A limit switch (132) is installed on one side of the manipulator (131) and can detect the position of at least one mold. For example, a micro switch, a roller lever switch, a plunger switch, a rotary switch, etc. can be applied as the limit switch (132).

[0467] Next, the injection nozzle (133) is installed at the end of the manipulator (131) to spray the release agent according to the position of the mold structure detected by the limit switch (132).

[0468] Here, a release agent can be used to prevent the molded product from bonding to the mold surface. Failure to do so can result in the molding material fusing with the mold. This release agent forms a barrier between the molded product and the mold surface, eliminating the adhesive between the molded product and the mold, preventing mold damage and facilitating the quick and easy removal of the molded product from the mold.

[0469] In addition, the injection unit (130) may be configured to include a vision sensor installed on the manipulator (131) to photograph at least one mold structure (110). In addition, the injection unit (130) may be configured to include an RFID reader capable of recognizing an RFID tag provided on the mold structure (110). In addition, the injection unit (130) may be configured to include a distance measuring sensor that measures the distance from the vision sensor to the mold.

[0470] In the following configuration, the control unit (140) can control at least one mold structure (110), a turn table (120), and an injection unit (130).

[0471] Specifically, when the mold is positioned at a preset position within the working range of the injection unit (130) by the turntable (120), the control unit (140) detects the edge of the mold through the limit switch (132), and controls the injection nozzle (133) to move in a zigzag pattern along the inner surface of the mold based on the edge detected through the manipulator (131) to spray the release agent.

[0472] At this time, the control unit (140) can control the injection nozzle (133) to move in a zigzag pattern along the inner surface of the mold based on the edge detected on the inner surface of the mold to first spray the release agent, and can control the injection nozzle (133) to move along the detected edge to second spray the release agent.

[0473] Meanwhile, in the case of a relatively complex structure depending on the shape of the inner surface of the mold, a large amount of release agent is required because the bonding area between the molded product and the mold is large, and in the case of a relatively simple structure, a small amount of release agent is required because the bonding area between the molded product and the mold is narrow.

[0474] Accordingly, the control unit (140) can recognize the shape of the inner surface of at least one mold through a vision sensor and adjust the amount of release agent sprayed for each part according to the recognized shape.

[0475] At this time, the control unit (140) accumulates and stores the injection amount of the release agent according to the recognized shape, and can determine the injection amount of the release agent for each part of the mold structure identified through artificial intelligence (AI) that has undergone machine learning in advance based on the accumulated and stored injection amount of the release agent.

[0476] That is, the control unit (140) can accumulate and store a design drawing that stores information on the amount of release agent to be sprayed for each part according to the type of mold, and can determine the amount of release agent to be sprayed for each part for a newly recognized mold through artificial intelligence that has been previously machine-learned based on the accumulated and stored design drawing.

[0477] In addition, the control unit (140) recognizes an RFID tag through an RFID reader to identify the location and type of the mold, and sets the movement path of the injection nozzle (133) based on the location and type of the identified mold, but compares the type of the identified mold with the shape of the mold recognized through a vision sensor to recognize the warpage of the mold, and can correct the set movement path according to the degree of warpage recognized.

[0478] In addition, the control unit (140) can capture a molded product injected from a mold through a vision sensor, analyze the surface of the molded product based on the captured image, and correct a preset movement path for the mold and the injection amount of a release agent based on the analysis results.

[0479] For example, the control unit (140) can determine the point where additional injection of the release agent is required or the point where the injection amount of the release agent must be increased through surface analysis of the completed molded product, and correct the movement path and the injection amount of the release agent.

[0480] In addition, the control unit (140) can generate a fused image including distance information per pixel by fusing an image of a mold captured from a vision sensor and distance information obtained from a distance measurement sensor, and generate a movement path of the injection nozzle based on the generated fused image.

[0481] At this time, the control unit (140) generates a movement path of the injection nozzle, and generates an x-axis movement path corresponding to the width of the inner surface of the mold based on the fusion image, and applies a y-axis coordinate corresponding to the depth of the inner surface of the mold to each coordinate of the x-axis movement path to generate a final movement path.

[0482] That is, the control unit (140) can accurately control the distribution of the release agent and improve the quality of the molded product by generating a movement path that takes into account the depth of the inner surface of the mold through a distance measuring sensor.

[0483] Hereinafter, the configuration of a full-length inspection device (200) according to one embodiment of the present invention will be described in detail.

[0484] Figure 34 is a top view showing the configuration of a full-length inspection device according to one embodiment of the present invention.

[0485] Referring to FIG. 34, a device (300) for inspection of a battlefield through noise analysis according to one embodiment of the present invention may be configured to include a booth (210), a conveyor (220), an inspection unit (230), and a control unit (240).

[0486] As for each component, the booth (210) forms a closed space, and at least one automobile seat (A) to be inspected can be placed therein.

[0487] Specifically, the booth (210) forms a soundproof space through which a conveyor (220) operating along a transport path can pass, and opening / closing doors (221) can be installed on both sides along the transport direction of the automobile seat (A). Here, the opening / closing door (221) can open / close an automobile seat input port (222) formed on one side of the booth (210) and open / close an automobile seat discharge port (223) formed on the other side of the booth (210).

[0488] The conveyor (220) can move at least one car seat (A) into the booth (210) or move an inspected car seat (A) out of the booth (210). Here, various conveyors capable of moving products, such as a belt conveyor, a screw conveyor, a bucket conveyor, a roller conveyor, and a trolley conveyor, can be applied.

[0489] The inspection unit (330) can obtain data generated from electronic equipment included in at least one automobile seat (A) when at least one automobile seat (A) is placed in a preset position inside the booth (210) via the conveyor (220).

[0490] Specifically, the inspection unit (330) may be configured with at least one microphone that detects noise generated from a car seat placed inside the booth. In addition, the inspection unit (330) may be configured to include a thermal imaging camera that detects radiant heat emitted from the car seat placed inside the booth. In addition, the inspection unit (330) may measure current generated from electronic components included in the car seat (A).

[0491] In the following configuration, the control unit (340) can control the booth (210), the conveyor (220), and the inspection unit (230). Specifically, the control unit (340) can apply power to at least one motor included in the automobile seat (A), detect noise generated from the motor according to the motor's operation, and compare the detected noise with pre-stored noise data to detect defects in the automobile seat.

[0492] At this time, the control unit (340) performs triangulation using the intensity of three or more noises received by multiple microphones, estimates the relative positional relationship between the multiple microphones and the noise generation area based on the performed triangulation, and detects a defective location by reflecting the estimated relative positional relationship.

[0493] Here, the control unit (340) can separate the detected noise into frequencies by sound wave and identify multiple motors based on the separated frequencies. At this time, the control unit (340) can identify the type of defect based on the separated frequency waveform through artificial intelligence (AI) that has undergone machine learning in advance based on the type of defect according to the frequency waveform.

[0494] In addition, the control unit (340) can apply power to a ventilation module included in the automobile seat (A), detect noise generated by the operation of the ventilation module, and compare the detected noise with pre-stored noise data to detect a defect in the automobile seat.

[0495] In addition, the control unit (340) can identify a plurality of heat source points based on a thermal image captured by a thermal imaging camera, generate an RGB (Red, Green, Blue) histogram for pixels included in an area within a preset distance from each of the plurality of heat source points, and compare the RGB histograms generated from areas corresponding to each of the plurality of heat source points to detect defects in the car seat. Here, the RGB histogram is a graph showing the brightness distribution of each primary color (RGB) in the image. For example, the RGB histogram has a horizontal axis that represents the brightness level of a color, and a vertical axis that represents the number of pixels assigned to the brightness level of a color. The more pixels there are to the left, the darker and less vivid the color is expressed, and the more pixels there are to the right, the brighter and more intense the color can be expressed. In this way, the control unit (340) can detect defects by comparing the saturation and gradation state of the color of the plurality of heat source point areas, the tendency of the white balance, etc. through the RGB histogram.

[0496] Additionally, the control unit (340) can detect defects in the car seat (A) by inputting a thermal image into an artificial intelligence (AI) model implemented with a convolutional neural network (CNN).

[0497] That is, the control unit (340) changes the resolution of the thermal image to generate an image group composed of multiple two-dimensional images with different resolutions, and then inputs all the two-dimensional images included in the image group into an artificial intelligence (AI) model implemented as a convolutional neural network (CNN), and then combines multiple result values ​​output from the artificial intelligence (AI) model to detect defects in the automobile seat (A).

[0498] Here, the convolutional neural network (CNN) can have a transformer encoder-decoder structure.

[0499] The control unit (340) converts the data constituting the thermal image into a single sequence by arranging them in a row and inputs the converted vector into an encoder, applies self-attention in the encoder to convert the data positions within the sequence into a single vector in which the data positions are connected to each other, and inputs the converted vector into a decoder, and uses a loss function based on the Hungarian algorithm in the decoder to detect defects in the car seat (A).

[0500] At this time, the encoder performs a convolution operation on the input feature map to generate an output feature map, and by reflecting a learnable offset in the size of the convolution filter, which is the area where features are extracted, the encoder can extract features from a grid area wider than the size of the convolution filter. In addition, the encoder can use the attention key as an offset when performing self-attention.

[0501]

[0502] Hereinafter, with reference to FIG. 35, the injection process of the injection automation device for the injection of the injection agent will be described.

[0503] Figure 35 is an exemplary diagram for explaining a disintegrant injection process of an automated disintegrant injection device according to one embodiment of the present invention.

[0504] Referring to FIG. 35, when the mold is positioned at a preset position within the working range of the injection unit by the turn table, the control unit (140) detects the edge of the mold through a limit switch, and controls the injection nozzle to move in a zigzag pattern along the inner surface of the mold based on the edge detected through the manipulator and spray the release agent.

[0505] At this time, the control unit (140) first injects the release agent (1) while the injection nozzle moves in a zigzag pattern on the inner side of the mold based on the edge detected on the inner side of the mold. st spray) and the release agent is sprayed secondarily (2) while the injection nozzle moves along the detected edge. nd It can be controlled to spray.

[0506] Meanwhile, in the case of a relatively complex structure depending on the shape of the inner surface of the mold, a large amount of release agent is required because the bonding area between the molded product and the mold is large, and in the case of a relatively simple structure, a small amount of release agent is required because the bonding area between the molded product and the mold is narrow.

[0507] Accordingly, the control unit (140) can recognize the shape of the inner surface of at least one mold through a vision sensor and adjust the amount of release agent sprayed for each part according to the recognized shape.

[0508] Below, with reference to Fig. 36, the process of detecting defects using an artificial intelligence model is described.

[0509] Figure 36 is an exemplary diagram for explaining the structure of an artificial intelligence (AI) model according to one embodiment of the present invention.

[0510] As illustrated in FIG. 36, the control unit (340) can input a thermal image into an artificial intelligence (AI) model implemented as a convolutional neural network (CNN). Here, the convolutional neural network (CNN) can have a transformer encoder-decoder structure.

[0511] More specifically, the control unit (340) can convert the data constituting the two-dimensional image into a single sequence by arranging them in a row and inputting the sequence into the encoder. The anomaly detection unit (330) can apply self-attention in the encoder to convert the data positions within the sequence into a single vector in which they are connected to each other, and then input the converted vector into the decoder. The control unit (340) outputs a result value using a loss function based on the Hungarian algorithm in the decoder. In addition, the control unit (340) can input the result value output from the decoder into a feed-forward network (FFN) to detect a defect.

[0512] In addition, the encoder of a convolutional neural network (CNN) according to one embodiment of the present invention may be modified to perform a convolution operation on an input feature map to generate an output feature map by reflecting a learnable offset in the size of a convolution filter, which is an area from which features are extracted, when performing the convolution operation. By this modification, the encoder can extract features from a grid area wider than the size of a convolution filter that is fixed.

[0513] In addition, the encoder of a convolutional neural network (CNN) according to one embodiment of the present invention can be modified to use an offset reflected in the size of a convolutional filter as an attention key when performing self-attention. By this modification, when a large object must be predicted from a two-dimensional image, a large offset is learned, and when a small object must be predicted, a small offset is learned, thereby improving the performance of a conventional convolutional neural network (CNN) that had relatively low prediction performance for small objects.

[0514] Meanwhile, the control unit (340) can determine whether there is an abnormality based on multiple two-dimensional images expanded in various ways from a single thermal image, rather than simply determining whether there is a defect in the car seat based on a single thermal image.

[0575] Here, the sheet tray (100), main frame (200), forward drive unit (300), and first story connector (400) are the same as the components of Fig. 37, so their descriptions are omitted to avoid duplication of explanation.

[0576] The seat cleaner (600) is installed at least once along the automobile production line (L) and removes foreign substances such as dust attached to the vehicle seat (S) moving by the seat tray (100) by spraying compressed air.

[0577] In one embodiment, the sheet cleaner (600) may include an installation housing (610), a rear cleaner (620), and a front cleaner (630).

[0578] The installation housing (610) is configured in a polygonal frame shape so that a vehicle seat (S) moving by a seat tray (100) can pass through the inside, and is installed in an automobile production line (L), and components such as a rear cleaning unit (620) and a front cleaning unit (630) are installed.

[0579] The rear cleaning unit (620) is installed on the inward surface of the vertical surface (611) formed at the rear end of the installation housing (610) facing the rear end of the vehicle seat (S) and sprays compressed air toward the rear end of the vehicle seat (S) to clean foreign substances such as dust.

[0580] The front cleaning unit (630) is installed on the inward surface of the front slope (612) of the installation housing (610) facing both the front of the backrest and the upper side of the cushion that constitute the vehicle seat (S) and sprays compressed air toward the front of the backrest and the upper side of the cushion to clean foreign substances such as dust.

[0581] In one embodiment, the shear cleaner (630) may include an inclined rail (631), a slider (632), a rail arm (633), and a cleaning module (700).

[0582] Here, the rear cleaning unit (620) has the same configuration as the front cleaning unit (630) described below, and the inclined rail (631), slider (632), rail arm (633), and cleaning module (700) of the front cleaning unit (630) can be applied in the same manner. Therefore, the description thereof will be omitted to avoid duplication of explanation.

[0583] The inclined rail (631) is formed to extend along the inward surface of the front inclined surface (612) of the installation housing (610) so that the slider (632) can be interlocked and installed to slide.

[0584] The slider (632) is installed in a manner that allows sliding movement on the inclined rail (631), and moves the rail arm (633) in response to the cleaning position.

[0585] Rail arms (633) are installed in multiple numbers so that they can be mutually rotated sequentially from the front end of the slider (632) to form multiple connecting joints (J), and each connecting joint is rotated so that it can face parallel to the backrest and cushion of the vehicle seat (S).

[0586] The cleaning module (700) is installed at least once on each lower surface of a plurality of rail arms (633) facing the vehicle seat (S), and performs cleaning by spraying compressed air toward the front of the backrest or the upper side of the cushion to remove foreign substances.

[0587] An auto docking system (20) according to another embodiment of the present invention having a configuration as described above can improve the manufacturing quality of a vehicle seat (S) without stopping the manufacturing process by removing foreign substances such as dust attached to the vehicle seat (S) without stopping during movement of the vehicle seat (S).

[0588] Figures 46 and 47 are drawings showing the cleaning module of Figure 45.

[0589] Referring to FIGS. 46 and 47, the cleaning module (700) includes a rail home (710), a module slider (720), a module body (730), a rotation guide home (740), a rotation spray unit (750), an actuator (760), and a spray nozzle (770).

[0590] The rail home (710) is formed to extend along the bottom surface of the rail arm (633) so that the module slider (720) can be engaged to enable sliding movement.

[0591] The module slider (720) slides along the rail home (710) to move the module body (730) to the compressed air injection position.

[0592] The module body (730) is installed at the bottom of the module slider (720), and components such as a rotation guide groove (740), a rotation injection unit (750), an actuator (760), and an injection nozzle (770) are installed.

[0593] The rotation guide groove (740) is formed to extend along the inside of the module body (730) while forming an opening at the bottom of the module body (730) so that the rotation injection part (750) can be engaged, inserted, or exposed, and forms a screw thread along the inner surface.

[0594] The rotary injection unit (750) is formed in a cylindrical shape and is installed in a manner that it is connected to the inner surface of the rotary guide groove (740) so that it can rotate in the internal space of the rotary guide groove (740), and is inserted into the inside of the rotary guide groove (740) or exposed from the rotary guide groove (740) as it rotates in the forward or reverse direction.

[0595] In one embodiment, the rotary injector (750) moves along the rotary injector groove (740) while rotating as the actuator (760) extends or contracts when the curved cover (757) described below is closely seated on the inner surface of the rotary injector groove (740) as it moves away from the injector body (751), and when the curved cover (757) is closely seated on the injector body (751) and separated from the inner surface of the rotary injector groove (740), the actuator (760) can move along the rotary injector groove (740) in a straight direction without rotating as it extends or contracts.

[0596] In one embodiment, the rotating injection unit (750) can reduce the spray angle of compressed air sprayed from the cleaning module (700) when inserted into the inside of the rail home (710) as shown in (a) of FIG. 47, thereby reducing the cleaning area by the compressed air, and can increase the spray angle of compressed air sprayed from the cleaning module (700) that moves forward toward the front end of the rail home (710) as shown in (b) of FIG. 47, thereby increasing the cleaning area by the compressed air.

[0597] The actuator (760) is installed inside the rotation guide groove (740) to support the rear end of the rotation injection unit (750), and is driven to extend or contract to move the rotation injection unit (750) forward or backward.

[0598] The injection nozzle (770) is installed along the front end of the rotating injection unit (750) and removes foreign substances by spraying compressed air supplied from a compressed air supply device installed externally (not shown in the drawing for convenience of explanation).

[0599] The cleaning module (700) having the configuration described above can improve the efficiency of removing foreign substances by inducing rotation of compressed air sprayed from the spray nozzle (770) or varying the spray angle of the compressed air by rotating the module body (730).

[0600] Figures 48 and 49 are drawings showing the rotating injector of Figure 47.

[0601] Referring to FIGS. 48 and 49, the rotary injector (750) includes an injector body (751), a hollow groove (752), a rotary column (753), a column driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), and a cover support spring (758).

[0602] The injection unit body (751) has a cylindrical shape in which an injection nozzle (770) is installed along a front end exposed from a rotation guide groove (740), and is installed so as to be rotatably connected to the front end of an actuator (760), and is configured with a hollow groove (752), a rotation pillar (753), a pillar driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), a first magnetic body (M1), a second magnetic body (M2), a cover support spring (758), and a magnetic switch (759).

[0603] The hollow groove (752) is formed hollow along the inside of the injection body (751) while the rotating column (753) is positioned and the “+” shaped rotor (755) is positioned to form sufficient space for rotation.

[0604] The rotating column (753) is positioned so as to be rotatable along the center of the internal space of the hollow groove (752), and is driven to rotate by the column driving motor (754) to rotate the “+”-shaped rotor (755) together.

[0605] The pillar drive motor (754) is installed upright on the upper side of the hollow groove (752), and the upper end of the rotary pillar (753) is installed on the drive shaft by shaft coupling to drive the rotation in the forward or reverse direction.

[0606] The "+" type rotor (755) is formed in a "+" shape with each of the four ends rounded, and is installed in multiple pieces by shaft coupling at regular intervals along the rotation column (753) to support each end of the horizontal movement frame (756) while rotating together as the rotational actuator rotates.

[0607] The horizontal movement frame (756) is inserted and penetrates the injection body (751) horizontally so that four of them are perpendicular to each other on the same plane, and is closely seated on the “+”-shaped rotor (755) in the hollow groove (752), and as the “+”-shaped rotor (755) rotates, each of them is horizontally moved simultaneously in a direction away from the rotation column (753) or approaching the rotation column (753) by the “+”-shaped rotor (755).

[0608] That is, the horizontal movement frame (756) can be moved horizontally in a direction away from the rotation column (753) as it is pressed against the end of each branch of the “+”-shaped rotor (755) and in a direction approaching the rotation column (753) as it is pressed against the corner between the branches of the “+”-shaped rotor (755).

[0609] The curved cover (757) is formed by roundly bending a flat plate, and is supported by a cover support spring (758) and installed at each front end of a plurality of horizontally moving frames (756) to cover the injection body (751), and forms a screw thread along the outward surface to engage with the screw thread of the inward surface of the rotation guide groove (740).

[0610] That is, the curved cover (757) moves away from the rotation pillar (753) as the horizontal movement frame (756) is pressed against the ends of each branch of the “+”-shaped rotor (755) and engages with the threads on the inward surface of the rotation guide groove (740), and moves horizontally in a direction approaching the rotation pillar (753) as the horizontal movement frame (756) is pressed against the corners between the branches of the “+”-shaped rotor (755) so that it can be separated from the threads on the inward surface of the rotation guide groove (740) along the outward surface.

[0611] The cover support spring (758) is installed between the curved cover (757) and the injection body (751) and pulls the curved cover (757) toward the injection body (751).

[0612] The rotary injection unit (750) having the configuration described above may further include a first magnetic body (M1), a second magnetic body (M2), and a magnetic switch (759).

[0613] The first magnetic body (M1) is installed on the inside of the curved cover (757) and forms a magnetism of the “N” pole or the “S” pole by the magnetic switch (759).

[0614] The second magnetic body (M2) is formed in a circular ring shape along the inner side of the rotation guide groove (740) facing the first magnetic body (M1), and forms a magnetism of “N” pole or “S” pole by the magnetic switch (759).

[0615] The magnetic switch (759) switches the magnetism of the first magnetic body (M1) and the second magnetic body (M2) to the “N” pole or the “S” pole to induce the curved cover (757) to be fastened to the inside of the rotation guide groove (740) or to be separated from the inside of the rotation guide groove (740).

[0616] The rotary injection unit (750) having the configuration described above can effectively and precisely achieve adhesion or separation with the inward surface of the rotary guide groove (740).

[0617] Fig. 50 is a drawing showing the injection nozzle of Fig. 47.

[0618] Referring to FIG. 50, the injection nozzle (770) includes a nozzle installation groove (771), an elastic cover (772), and a plurality of nozzles (773).

[0619] The nozzle installation groove (771) is formed by recessing into the front end of the rotating injection unit (750).

[0620] The elastic cover (772) is made of an elastic material that can be expanded or contracted and is installed to cover the front opening of the nozzle installation groove (771). As a fluid, such as water or oil, is supplied to the nozzle installation groove (771), the elastic cover expands into a hemispherical shape by hydraulic pressure and returns to a flat shape as the fluid is discharged from the nozzle installation groove (771).

[0621] A plurality of nozzles (773) are installed radially along the elastic cover (772) to spray compressed air. When the elastic cover (772) is flat, the compressed air is sprayed in a direction perpendicular to the elastic cover (772), and the spraying direction of the compressed air changes as the elastic cover (772) expands.

[0622] The spray nozzle (770) having the configuration described above can improve the efficiency of removing foreign substances by varying and precisely changing the spray area of ​​compressed air sprayed through the nozzle (773) as the elastic cover (772) contracts as shown in (a) of FIG. 50 or expands as shown in (b) of FIG. 50.

[0623] Figure 51 is a diagram schematically illustrating a configuration of a gap measurement system according to one embodiment of the present invention.

[0625] The main frame (100) is installed on one side of an automobile production line (L) for moving a seat tray on which a vehicle seat (S) (e.g., a third-row seat of a vehicle) on which a first sheet (S1) and a second sheet (S2) are installed in close contact is installed.

[0626] In one embodiment, the main frame (100) is configured with a high-strength profile to improve the structural stability of the equipment, and a reinforcing member (110) is installed between the main frame (100) and the rail frame (200) to structurally reinforce the shaking of the protrudingly installed rail frame (200).

[0627] The rail frame (200) is installed horizontally while looking at the automobile production line (L) from the top of the main frame (100), and components such as the inspection unit (300) are installed.

[0628] The inspection unit (300) is installed in a sliding manner in a rail frame (200), moves backward along the rail frame (200) to approach the main frame (100) when the vehicle seat (S) moves, and moves forward along the rail frame (200) to face the measurement position of the vehicle seat (S) when measuring the gap of the vehicle seat (S), and senses the gap between the first sheet (S1) and the second sheet (S2) (i.e., the step difference between the first sheet (S1) and the second sheet (S2).

[0629] In one embodiment, the inspection unit (300) can sense the gap between the first seat (S1) and the second seat (S2) while looking downward after moving forward before tilting the vehicle seat (S) as shown in FIG. 52, and can sense the gap between the first seat (S1) and the second seat (S2) while looking forward after being positioned close to the main frame (100) after tilting the vehicle seat (S) as shown in FIG. 53.

[0630] The quality reading unit (400) uses sensing information transmitted from the inspection unit (300) to read whether the vehicle seat (S) is quality by determining whether the gap between the first sheet (S1) and the second sheet (S2) is within the error range.

[0631] The gap measurement system (10) according to one embodiment of the present invention having the configuration described above can determine whether the vehicle seat is operating normally based on the customer's standards by sequentially verifying the vehicle seat twice, before and after tilting.

[0632] A gap measurement system (10) according to one embodiment of the present invention having a configuration as described above can measure whether the gap between two seats in a three-row vehicle seat manufactured by closely arranging the two seats is within an error range, thereby determining whether the vehicle seat is defective.

[0633] In addition, by using one system, it is possible to determine whether the vehicle seat is defective by measuring whether the step difference is within the error range before tilting the vehicle seat as shown in Fig. 52 and after tilting as shown in Fig. 53.

[0634] Figure 54 is a drawing showing the rail frame of Figure 51.

[0635] Referring to FIG. 54, the rail frame (200) includes a horizontal frame (210), a sliding hole (220), a servo motor (230), and a ball screw (240).

[0636] The horizontal frame (210) is installed at the top of the main frame (100) while looking at the automobile production line (L) at a right angle to the direction of movement of the vehicle seat (S), and components such as a sliding hole (220), a servo motor (230), and a ball screw (240) are installed.

[0637] The sliding hole (220) is formed to extend in the longitudinal direction along the break of the horizontal frame (210) so that the upper part of the inspection unit (300) can be settled and moved, and components such as the sliding hole (220), servo motor (230), and ball screw (240) are installed.

[0638] The servo motor (230) is installed on the upper rear side of the horizontal frame (210) and drives the ball screw (240) to rotate in the forward or reverse direction.

[0639] The ball screw (240) is installed by shaft coupling to the drive shaft of the servo motor (230) and is positioned along the upper side of the sliding hole, and is connected and interlocked with the upper end of the inspection section (300) by bolt coupling, and is driven to rotate in the forward or reverse direction by the servo motor (230) to move the inspection section (300) forward or backward along the sliding hole (220).

[0640] The rail frame (200) having the configuration described above is installed while facing the production line (L) to stably support the inspection unit (300) and precisely slide the inspection unit (300) in response to the sensing position of the inspection unit (300).

[0641] Figure 55 is a drawing showing the inspection section of Figure 51.

[0642] Referring to FIG. 55, the inspection unit (300) includes a horizontal slider (310), a vertical body (320), a sensor casing (330), a gap measurement sensor (340), and a bundle connecting unit (350).

[0643] The horizontal slider (310) is installed in the sliding hole (220) and is interlocked with the ball screw (240) by a bolt and nut combination, and moves along the sliding hole (220) as the ball screw (240) rotates in the forward or reverse direction.

[0644] In one embodiment, the horizontal slider (310) may include a connecting nut (311) and a nut support (312), as illustrated in FIG. 54.

[0645] The connecting nut (311) is installed by being interlocked with the ball screw (240) through a bolt nut combination, and moves the nut support (312) while moving along the ball screw (240) as the ball screw (240) rotates in the forward or reverse direction.

[0646] The nut support (312) is installed at the top of the vertical body (320) and is mounted on the connecting nut (311), and moves along the sliding hole (220) as the connecting nut (311) moves.

[0647] A horizontal slider (310) having a configuration as described above may further include a guide rail (313) and a guide (314).

[0648] The guide rail (313) is installed along one side and the other side of the downward surface of the horizontal frame (210) with a sliding hole (220) between them so that the guide (314) can be interlocked, connected, and moved.

[0649] The guide (314) is installed on one side and the other side of the upper part of the vertical body (320) and is connected to the guide rail (313) so as to slide along the guide rail (313) and guide the horizontal movement of the vertical body (320).

[0650] The vertical body (320) is installed on the lower side of the horizontal slider (310).

[0651] The sensor casing (330) is placed on the lower side of the vertical body (320).

[0652] The gap measurement sensor (340) is installed in the sensor casing (330) and senses the gap between the first sheet (S1) and the second sheet (S2).

[0653] In one embodiment, the gap measurement sensor (340) is installed on the lower side of the sensor casing (330) as illustrated in FIG. 52 and can sense the gap between the first sheet (S1) and the second sheet (S2) in a folded state on the lower side.

[0654] In one embodiment, the gap measurement sensor (340) can sense the gap between the first sheet (S1) and the second sheet (S2) in an unfolded state at the front when the mounting arm (354) is rotationally driven so that the lower side of the sensor casing (330) faces forward, as illustrated in FIG. 53.

[0655] The bundle connecting portion (350) interconnects the vertical body (320) and the sensor casing (330).

[0656] The inspection unit (300) having the configuration described above can precisely change the angle for sensing as well as precisely move the gap measurement sensor (340) performing sensing in the forward and backward directions and up and down directions.

[0657] That is, the inspection unit (300) having the configuration described above can, as shown in FIG. 52, in the case before tilting of the vehicle seat, the horizontal slider (310) moves forward along the rail frame (200), and then moves the sensor casing (330) downward, and at the same time, tilt the gap measurement sensor (340) so that it faces downward, and then perform sensing. As shown in FIG. 53, in the case after tilting of the vehicle seat, the horizontal slider (310) moves backward along the rail frame (200) to move close to the main frame (100), and then moves the sensor casing (330) upward, and at the same time, tilt the gap measurement sensor (340) so that it faces forward, and then perform sensing. Therefore, the inconvenience of having to provide various types of sensing devices depending on whether the vehicle seat is tilted can be solved.

[0658] Figures 56 and 57 are drawings showing the bundle connection of Figure 55.

[0659] Referring to FIGS. 56 and 57, the bundle connecting portion (350) includes a vertical cylinder (351), a connecting plate (352), a rotating cylinder (353), and a mounting arm (354).

[0660] The vertical cylinder (351) is installed on the lower side of the vertical body (320) and moves the connection plate (352) vertically in the up-and-down direction while driving the expansion or contraction in the up-and-down direction to move the gap measurement sensor (340) to the sensing position.

[0661] In one embodiment, the vertical cylinder (351) can be driven to contract and move the sensor casing (330) upward so that interference between the first sheet (S1) and the second sheet (S2) does not occur when the first sheet (S1) and the second sheet (S2) are folded or unfolded.

[0662] The connecting plate (352) moves up and down vertically by a vertical cylinder (351).

[0663] A rotating cylinder (353) is installed on one side of the connecting plate (352) and drives the mounting arm (354) to rotate.

[0664] The mounting arm (354) is installed by means of an axial coupling to the rotation axis of the rotation cylinder (353) to mount the sensor casing (330), and is rotationally driven by the rotation cylinder (353) to rotationally drive the sensor casing (330).

[0665] The bundle connecting part (350) having the configuration described above can enable precise sensing to be performed without being restricted by the sensing position of the vehicle seat by tilting the gap measuring sensor (340) in response to the sensing position of the gap measuring sensor (340) as well as in the vertical and vertical directions, as shown in FIG. 57.

[0666] Figure 58 is a drawing schematically illustrating a configuration of a gap measurement system according to another embodiment of the present invention.

[0668] Here, the main frame (100), rail frame (200), inspection unit (300), and good product reading unit (400) are the same as the components of Fig. 51, so their descriptions are omitted to avoid duplication of explanation.

[0669] The calibration unit (500) is installed in the main frame (100) to perform sensing calibration of the inspection unit (300).

[0670] In one embodiment, it may include a connecting member (510), a horizontal plate (520), and a calibration block (530).

[0671] The connecting member (510) is installed on the main frame (100) facing the inspection unit (300) so that a horizontal plate (520) can be installed.

[0672] A horizontal plate (520) is installed at the front end of the connecting member (510) so that a calibration block (530) can be installed.

[0673] The calibration block (530) is installed on the top of the horizontal plate (520), and steps with a constant height difference are repeatedly formed along the top.

[0674] In one embodiment, the inspection unit (300) can perform calibration by detecting the line of the step of the calibration block (530), and perform sensing after the calibration is completed.

[0675] The gap measurement system (20) according to another embodiment of the present invention having the configuration described above can always ensure accurate sensing without the need for unnecessary devices by performing calibration by the system itself without separate calibration equipment.

[0676] Figure 59 is a diagram schematically illustrating a configuration of a gap measurement system according to another embodiment of the present invention.

[0677] Referring to FIG. 59, a gap measurement system (30) according to another embodiment of the present invention includes a sheet tray (100), a main frame (200), a forward driving unit (300), a first storage connector (400), and a sheet cleaning unit (600).

[0678] Here, the sheet tray (100), main frame (200), forward drive unit (300), and first story connector (400) are the same as the components of Fig. 51, so their descriptions are omitted to avoid duplication of explanation.

[0679] The seat cleaner (600) is installed at least once along the automobile production line (L) and removes foreign substances such as dust attached to the vehicle seat (S) moving by the seat tray (100) by spraying compressed air.

[0680] In one embodiment, the sheet cleaner (600) may include an installation housing (610), a rear cleaner (620), and a front cleaner (630).

[0681] The installation housing (610) is configured in a polygonal frame shape so that a vehicle seat (S) moving by a seat tray (100) can pass through the inside, and is installed in an automobile production line (L), and components such as a rear cleaning unit (620) and a front cleaning unit (630) are installed.

[0682] The rear cleaning unit (620) is installed on the inward surface of the vertical surface (611) formed at the rear end of the installation housing (610) facing the rear end of the vehicle seat (S) and sprays compressed air toward the rear end of the vehicle seat (S) to clean foreign substances such as dust.

[0683] The front cleaning unit (630) is installed on the inward surface of the front slope (612) of the installation housing (610) facing both the front of the backrest and the upper side of the cushion that constitute the vehicle seat (S) and sprays compressed air toward the front of the backrest and the upper side of the cushion to clean foreign substances such as dust.

[0684] In one embodiment, the shear cleaner (630) may include an inclined rail (631), a slider (632), a rail arm (633), and a cleaning module (700).

[0685] Here, the rear cleaning unit (620) has the same configuration as the front cleaning unit (630) described below, and the inclined rail (631), slider (632), rail arm (633), and cleaning module (700) of the front cleaning unit (630) can be applied in the same manner. Therefore, the description thereof will be omitted to avoid duplication of explanation.

[0686] The inclined rail (631) is formed to extend along the inward surface of the front inclined surface (612) of the installation housing (610) so that the slider (632) can be interlocked and installed to slide.

[0687] The slider (632) is installed in a manner that allows sliding movement on the inclined rail (631), and moves the rail arm (633) in response to the cleaning position.

[0688] Rail arms (633) are installed in multiple numbers so that they can be mutually rotated sequentially from the front end of the slider (632) to form multiple connecting joints (J), and each connecting joint is rotated so that it can face parallel to the backrest and cushion of the vehicle seat (S).

[0689] The cleaning module (700) is installed at least once on each lower surface of a plurality of rail arms (633) facing the vehicle seat (S), and performs cleaning by spraying compressed air toward the front of the backrest or the upper side of the cushion to remove foreign substances.

[0690] A gap measurement system (30) according to another embodiment of the present invention having a configuration as described above can improve the manufacturing quality of a vehicle seat (S) without stopping the manufacturing process by removing foreign substances such as dust attached to the vehicle seat (S) without stopping during movement of the vehicle seat (S).

[0691] Figures 60 and 61 are drawings showing the cleaning module of Figure 59.

[0692] Referring to FIGS. 60 and 61, the cleaning module (700) includes a rail home (710), a module slider (720), a module body (730), a rotation guide home (740), a rotation spray unit (750), an actuator (760), and a spray nozzle (770).

[0693] The rail home (710) is formed to extend along the bottom surface of the rail arm (633) so that the module slider (720) can be engaged to enable sliding movement.

[0694] The module slider (720) slides along the rail home (710) to move the module body (730) to the compressed air injection position.

[0695] The module body (730) is installed at the bottom of the module slider (720), and components such as a rotation guide groove (740), a rotation injection unit (750), an actuator (760), and an injection nozzle (770) are installed.

[0696] The rotation guide groove (740) is formed to extend along the inside of the module body (730) while forming an opening at the bottom of the module body (730) so that the rotation injection part (750) can be engaged, inserted, or exposed, and forms a screw thread along the inner surface.

[0697] The rotary injection unit (750) is formed in a cylindrical shape and is installed in a manner that it is connected to the inner surface of the rotary guide groove (740) so that it can rotate in the internal space of the rotary guide groove (740), and is inserted into the inside of the rotary guide groove (740) or exposed from the rotary guide groove (740) as it rotates in the forward or reverse direction.

[0698] In one embodiment, the rotary injector (750) moves along the rotary injector groove (740) while rotating as the actuator (760) extends or contracts when the curved cover (757) described below is closely seated on the inner surface of the rotary injector groove (740) as it moves away from the injector body (751), and when the curved cover (757) is closely seated on the injector body (751) and separated from the inner surface of the rotary injector groove (740), the actuator (760) can move along the rotary injector groove (740) in a straight direction without rotating as it extends or contracts.

[0699] In one embodiment, the rotating injection unit (750) can reduce the spray angle of compressed air sprayed from the cleaning module (700) when inserted into the inside of the rail home (710) as shown in (a) of FIG. 61, thereby reducing the cleaning area by the compressed air, and can increase the spray angle of compressed air sprayed from the cleaning module (700) that moves forward toward the front end of the rail home (710) as shown in (b) of FIG. 61, thereby increasing the cleaning area by the compressed air.

[0700] The actuator (760) is installed inside the rotation guide groove (740) to support the rear end of the rotation injection unit (750), and is driven to extend or contract to move the rotation injection unit (750) forward or backward.

[0701] The injection nozzle (770) is installed along the front end of the rotating injection unit (750) and removes foreign substances by spraying compressed air supplied from a compressed air supply device installed externally (not shown in the drawing for convenience of explanation).

[0702] The cleaning module (700) having the configuration described above can improve the efficiency of removing foreign substances by inducing rotation of compressed air sprayed from the spray nozzle (770) or varying the spray angle of the compressed air by rotating the module body (730).

[0703] Figures 62 and 63 are drawings showing the rotating injector of Figure 61.

[0704] Referring to FIGS. 62 and 63, the rotary injector (750) includes an injector body (751), a hollow groove (752), a rotary column (753), a column driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), and a cover support spring (758).

[0705] The injection unit body (751) has a cylindrical shape in which an injection nozzle (770) is installed along a front end exposed from a rotation guide groove (740), and is installed so as to be rotatably connected to the front end of an actuator (760), and is configured with a hollow groove (752), a rotation pillar (753), a pillar driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), a first magnetic body (M1), a second magnetic body (M2), a cover support spring (758), and a magnetic switch (759).

[0706] The hollow groove (752) is formed hollow along the inside of the injection body (751) while the rotating column (753) is positioned and the “+” shaped rotor (755) is positioned to form sufficient space for rotation.

[0707] The rotating column (753) is positioned so as to be rotatable along the center of the internal space of the hollow groove (752), and is driven to rotate by the column driving motor (754) to rotate the “+”-shaped rotor (755) together.

[0708] The pillar drive motor (754) is installed upright on the upper side of the hollow groove (752), and the upper end of the rotary pillar (753) is installed on the drive shaft by shaft coupling to drive the rotation in the forward or reverse direction.

[0709] The "+" type rotor (755) is formed in a "+" shape with each of the four ends rounded, and is installed in multiple pieces by shaft coupling at regular intervals along the rotation column (753) to support each end of the horizontal movement frame (756) while rotating together as the rotational actuator rotates.

[0710] The horizontal movement frame (756) is inserted and penetrates the injection body (751) horizontally so that four of them are perpendicular to each other on the same plane, and is closely seated on the “+”-shaped rotor (755) in the hollow groove (752), and as the “+”-shaped rotor (755) rotates, each of them is horizontally moved simultaneously in a direction away from the rotation column (753) or approaching the rotation column (753) by the “+”-shaped rotor (755).

[0711] That is, the horizontal movement frame (756) can be moved horizontally in a direction away from the rotation column (753) as it is pressed against the end of each branch of the “+”-shaped rotor (755) and in a direction approaching the rotation column (753) as it is pressed against the corner between the branches of the “+”-shaped rotor (755).

[0712] The curved cover (757) is formed by roundly bending a flat plate, and is supported by a cover support spring (758) and installed at each front end of a plurality of horizontally moving frames (756) to cover the injection body (751), and forms a screw thread along the outward surface to engage with the screw thread of the inward surface of the rotation guide groove (740).

[0713] That is, the curved cover (757) moves away from the rotation pillar (753) as the horizontal movement frame (756) is pressed against the ends of each branch of the “+”-shaped rotor (755) and engages with the threads on the inward surface of the rotation guide groove (740), and moves horizontally in a direction approaching the rotation pillar (753) as the horizontal movement frame (756) is pressed against the corners between the branches of the “+”-shaped rotor (755) so that it can be separated from the threads on the inward surface of the rotation guide groove (740) along the outward surface.

[0714] The cover support spring (758) is installed between the curved cover (757) and the injection body (751) and pulls the curved cover (757) toward the injection body (751).

[0715] The rotary injection unit (750) having the configuration described above may further include a first magnetic body (M1), a second magnetic body (M2), and a magnetic switch (759).

[0716] The first magnetic body (M1) is installed on the inside of the curved cover (757) and forms a magnetism of the “N” pole or the “S” pole by the magnetic switch (759).

[0717] The second magnetic body (M2) is formed in a circular ring shape along the inner side of the rotation guide groove (740) facing the first magnetic body (M1), and forms a magnetism of “N” pole or “S” pole by the magnetic switch (759).

[0718] The magnetic switch (759) switches the magnetism of the first magnetic body (M1) and the second magnetic body (M2) to the “N” pole or the “S” pole to induce the curved cover (757) to be fastened to the inside of the rotation guide groove (740) or to be separated from the inside of the rotation guide groove (740).

[0719] The rotary injection unit (750) having the configuration described above can effectively and precisely achieve adhesion or separation with the inward surface of the rotary guide groove (740).

[0720] Fig. 64 is a drawing showing the injection nozzle of Fig. 61.

[0721] Referring to FIG. 64, the injection nozzle (770) includes a nozzle installation groove (771), an elastic cover (772), and a plurality of nozzles (773).

[0722] The nozzle installation groove (771) is formed by recessing into the front end of the rotating injection unit (750).

[0723] The elastic cover (772) is made of an elastic material that can be expanded or contracted and is installed to cover the front opening of the nozzle installation groove (771). As a fluid, such as water or oil, is supplied to the nozzle installation groove (771), the elastic cover expands into a hemispherical shape by hydraulic pressure and returns to a flat shape as the fluid is discharged from the nozzle installation groove (771).

[0724] A plurality of nozzles (773) are installed radially along the elastic cover (772) to spray compressed air. When the elastic cover (772) is flat, the compressed air is sprayed in a direction perpendicular to the elastic cover (772), and the spraying direction of the compressed air changes as the elastic cover (772) expands.

[0725] The spray nozzle (770) having the configuration described above can improve the efficiency of removing foreign substances by precisely and variously varying the spray area of ​​compressed air sprayed through the nozzle (773) as the elastic cover (772) contracts as shown in (a) of FIG. 64 or expands as shown in (b) of FIG. 64.

[0726] FIG. 65 is a schematic diagram illustrating a configuration of a sheet driving pressure inspection system according to one embodiment of the present invention.

[0727] Referring to FIG. 65, a sheet drive pressure inspection system (10) according to one embodiment of the present invention includes a main frame (100), a rail frame (200), two sensing units (300-1, 300-2), and a good product reading unit (400).

The external cover is made of the same material to protect the electrical components placed inside the system control box from dust or foreign substances generated from the outside, and a reinforcing bar (110) is provided between the main frame (100) and the rail frame (200) to minimize the shaking of the rail frame (200) that is protrudingly installed.

[0732] The rail frame (200) is installed horizontally while looking at the automobile production line (L) from the top of the main frame (100).

[0733] The two sensing units (300-1, 300-2) are installed in a sliding manner on the rail frame (200), and move backward along the rail frame (200) to approach the main frame (100) when the vehicle seat (S) moves, and move forward along the rail frame (200) to face the measurement position of the vehicle seat (S) when measuring the driving pressure of the vehicle seat (S), and sense the driving pressure when the first seat (S1) and the second seat (S2) are folded or unfolded.

[0734] In one embodiment, two sensing units (300-1, 300-2) can move in response to the measurement position of the anti-pinch according to the type of sheet produced in real time.

[0735] The quality reading unit (400) uses sensing information transmitted from the sensing unit (300) to read whether the vehicle seat (S) is quality.

[0736] The sheet driving pressure inspection system (10) according to one embodiment of the present invention having the configuration described above can sense the driving pressure not only in the case of the first sheet (S1) and the second sheet (S2) being folded from an unfolded state as shown in FIG. 66 through one system, but also in the case of the first sheet (S1) and the second sheet (S2) being unfolded from a folded state as shown in FIG. 67.

[0737] The seat drive pressure inspection system (10) according to one embodiment of the present invention having the configuration described above can check whether the anti-pinch function is functioning without a problem by placing a head on a vehicle seat that is being folded or unfolded through servo control and then measuring a certain amount of load.

[0738] In addition, the anti-pinch measurement location can be identified according to the vehicle model of the vehicle seat produced in real time, and the anti-pinch can be verified for each load based on the customer's standards to determine whether the product is functioning before the vehicle seat is shipped.

[0739] Fig. 68 is a drawing showing the rail frame of Fig. 65.

[0740] Referring to FIG. 68, the rail frame (200) includes a horizontal frame (210), two sliding holes (220), two servo motors (230), and two ball screws (240).

[0749] The vertical body (320) is installed on the lower side of the horizontal slider (310) and has a mounting part (330).

[0750] The support member (330) is placed at the front end of the vertical body (320).

[0751] The driving unit (340) interconnects the vertical body (320) and the mounting unit (330).

[0752] In one embodiment, the drive unit (340) may include a lifting cylinder (341) and a rotating cylinder (342).

[0753] The lifting cylinder (341) is installed at the front end of the vertical body (320), and moves the mounting portion (330) up and down while driving the vertical extension or contraction in the vertical direction, thereby moving the sensor portion (350) to the sensing position by the sensor portion (350).

[0754] In one embodiment, the lifting cylinder (341) can be driven to elongate or contract in response to a sensing position where the sensing block (352) is in close contact when the first sheet (S1) and the second sheet (S2) are folded or unfolded, thereby moving the sensing block (352) up and down.

[0755] The rotating cylinder (342) rotates the mounting portion (330) to tilt the sensor portion (350) to the sensing position by the sensor portion (350).

[0756] In one embodiment, the rotating cylinder (342) can be placed upright with the sensor unit (350) facing downward so that the sensor unit (350) can sense the driving pressure for unfolding the first sheet (S1) and the second sheet (S2) in the folded state when unfolding, as illustrated in FIG. 67.

[0757] In one embodiment, the rotating cylinder (342) can be horizontally arranged so that the sensor unit (350) faces forward so that the sensor unit (350) can sense the driving pressure for folding the first sheet (S1) and the second sheet (S2) in the unfolded state when folding, as shown in FIG. 66.

[0758] The sensor unit (350) is installed in the mounting unit (330) and senses the driving pressure when the first sheet (S1) and the second sheet (S2) are folded or unfolded.

[0768] Referring to FIG. 70, the horizontal slider (310) includes a connecting nut (311) and a nut support (312).

[0769] The connecting nut (311) is installed by being interlocked with the ball screw (240) through a bolt nut combination as shown in Fig. 65, and moves the nut support (312) while moving along the ball screw (240) as the ball screw (240) rotates in the forward or reverse direction.

[0770] The nut support (312) is installed at the top of the vertical body (320) and is mounted on the connecting nut (311), and moves along the sliding hole (220) as the connecting nut (311) moves.

[0771] A horizontal slider (310) having a configuration as described above may further include two guide rails (313) and two guides (314).

[0772] Two guide rails (313) are installed spaced apart from each other on the downward surface of the horizontal frame (210) with a sliding hole (220) between them.

[0773] Two guides (314) are installed on one side and the other side of the upper part of the vertical body (320) and are connected to the guide rail (313) so as to slide along the guide rail (313).

[0774] A horizontal slider (310) having a configuration as described above can perform precise movement in the forward and backward directions of a sensor unit (350) that performs sensing.

[0775] Figure 71 is a drawing schematically illustrating a configuration of a sheet driving pressure inspection system according to another embodiment of the present invention.

[0776] Referring to FIG. 71, a sheet drive pressure inspection system (20) according to another embodiment of the present invention includes a sheet tray (100), a main frame (200), a forward drive unit (300), a first story connector (400), and a sheet cleaning unit (600).

[0777] Here, the sheet tray (100), main frame (200), forward drive unit (300), and first story connector (400) are the same as the components of Fig. 65, so their descriptions are omitted to avoid duplication of explanation.

[0778] The seat cleaner (600) is installed at least once along the automobile production line (L) and removes foreign substances such as dust attached to the vehicle seat (S) moving by the seat tray (100) by spraying compressed air.

[0779] In one embodiment, the sheet cleaner (600) may include an installation housing (610), a rear cleaner (620), and a front cleaner (630).

[0780] The installation housing (610) is configured in a polygonal frame shape so that a vehicle seat (S) moving by a seat tray (100) can pass through the inside, and is installed in an automobile production line (L), and components such as a rear cleaning unit (620) and a front cleaning unit (630) are installed.

[0781] The rear cleaning unit (620) is installed on the inward surface of the vertical surface (611) formed at the rear end of the installation housing (610) facing the rear end of the vehicle seat (S) and sprays compressed air toward the rear end of the vehicle seat (S) to clean foreign substances such as dust.

[0782] The front cleaning unit (630) is installed on the inward surface of the front slope (612) of the installation housing (610) facing both the front of the backrest and the upper side of the cushion that constitute the vehicle seat (S) and sprays compressed air toward the front of the backrest and the upper side of the cushion to clean foreign substances such as dust.

[0783] In one embodiment, the shear cleaner (630) may include an inclined rail (631), a slider (632), a rail arm (633), and a cleaning module (700).

[0784] Here, the rear cleaning unit (620) has the same configuration as the front cleaning unit (630) described below, and the inclined rail (631), slider (632), rail arm (633), and cleaning module (700) of the front cleaning unit (630) can be applied in the same manner. Therefore, the description thereof will be omitted to avoid duplication of explanation.

[0785] The inclined rail (631) is formed to extend along the inward surface of the front inclined surface (612) of the installation housing (610) so that the slider (632) can be interlocked and installed to slide.

[0786] The slider (632) is installed in a manner that allows sliding movement on the inclined rail (631), and moves the rail arm (633) in response to the cleaning position.

[0787] Rail arms (633) are installed in multiple numbers so that they can be mutually rotated sequentially from the front end of the slider (632) to form multiple connecting joints (J), and each connecting joint is rotated so that it can face parallel to the backrest and cushion of the vehicle seat (S).

[0788] The cleaning module (700) is installed at least once on each lower surface of a plurality of rail arms (633) facing the vehicle seat (S), and performs cleaning by spraying compressed air toward the front of the backrest or the upper side of the cushion to remove foreign substances.

[0789] A seat drive pressure inspection system (20) according to another embodiment of the present invention having a configuration as described above can improve the manufacturing quality of a vehicle seat (S) without stopping the manufacturing process by removing foreign substances such as dust attached to the vehicle seat (S) without stopping during the movement of the vehicle seat (S).

[0790] Figures 72 and 73 are drawings showing the cleaning module of Figure 71.

[0791] Referring to FIGS. 72 and 73, the cleaning module (700) includes a rail home (710), a module slider (720), a module body (730), a rotation guide home (740), a rotation spray unit (750), an actuator (760), and a spray nozzle (770).

[0792] The rail home (710) is formed to extend along the bottom surface of the rail arm (633) so that the module slider (720) can be engaged to enable sliding movement.

[0793] The module slider (720) slides along the rail home (710) to move the module body (730) to the compressed air injection position.

[0794] The module body (730) is installed at the bottom of the module slider (720), and components such as a rotation guide groove (740), a rotation injection unit (750), an actuator (760), and an injection nozzle (770) are installed.

[0795] The rotation guide groove (740) is formed to extend along the inside of the module body (730) while forming an opening at the bottom of the module body (730) so that the rotation injection part (750) can be engaged, inserted, or exposed, and forms a screw thread along the inner surface.

[0796] The rotary injection unit (750) is formed in a cylindrical shape and is installed in a manner that it is connected to the inner surface of the rotary guide groove (740) so that it can rotate in the internal space of the rotary guide groove (740), and is inserted into the inside of the rotary guide groove (740) or exposed from the rotary guide groove (740) as it rotates in the forward or reverse direction.

[0797] In one embodiment, the rotary injector (750) moves along the rotary injector groove (740) while rotating as the actuator (760) extends or contracts when the curved cover (757) described below is closely seated on the inner surface of the rotary injector groove (740) as it moves away from the injector body (751), and when the curved cover (757) is closely seated on the injector body (751) and separated from the inner surface of the rotary injector groove (740), the actuator (760) can move along the rotary injector groove (740) in a straight direction without rotating as it extends or contracts.

[0798] In one embodiment, the rotating injection unit (750) can reduce the spray angle of compressed air sprayed from the cleaning module (700) when inserted into the inside of the rail home (710) as shown in (a) of FIG. 73, thereby reducing the cleaning area by the compressed air, and can increase the spray angle of compressed air sprayed from the cleaning module (700) that moves forward toward the front end of the rail home (710) as shown in (b) of FIG. 73, thereby increasing the cleaning area by the compressed air.

[0799] The actuator (760) is installed inside the rotation guide groove (740) to support the rear end of the rotation injection unit (750), and is driven to extend or contract to move the rotation injection unit (750) forward or backward.

[0800] The injection nozzle (770) is installed along the front end of the rotating injection unit (750) and removes foreign substances by spraying compressed air supplied from a compressed air supply device installed externally (not shown in the drawing for convenience of explanation).

[0801] The cleaning module (700) having the configuration described above can improve the efficiency of removing foreign substances by inducing rotation of compressed air sprayed from the spray nozzle (770) or varying the spray angle of the compressed air by rotating the module body (730).

[0802] Figures 74 and 75 are drawings showing the rotating injector of Figure 73.

[0803] Referring to FIGS. 74 and 75, the rotary injector (750) includes an injector body (751), a hollow groove (752), a rotary column (753), a column driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), and a cover support spring (758).

[0804] The injection unit body (751) has a cylindrical shape in which an injection nozzle (770) is installed along a front end exposed from a rotation guide groove (740), and is installed so as to be rotatably connected to the front end of an actuator (760), and is configured with a hollow groove (752), a rotation pillar (753), a pillar driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), a first magnetic body (M1), a second magnetic body (M2), a cover support spring (758), and a magnetic switch (759).

[0805] The hollow groove (752) is formed hollow along the inside of the injection body (751) while the rotating column (753) is positioned and the “+” shaped rotor (755) is positioned to form sufficient space for rotation.

[0806] The rotating column (753) is positioned so as to be rotatable along the center of the internal space of the hollow groove (752), and is driven to rotate by the column driving motor (754) to rotate the “+”-shaped rotor (755) together.

[0807] The pillar drive motor (754) is installed upright on the upper side of the hollow groove (752), and the upper end of the rotary pillar (753) is installed on the drive shaft by shaft coupling to drive the rotation in the forward or reverse direction.

[0808] The "+" type rotor (755) is formed in a "+" shape with each of the four ends rounded, and is installed in multiple pieces by shaft coupling at regular intervals along the rotation column (753) to support each end of the horizontal movement frame (756) while rotating together as the rotational actuator rotates.

[0809] The horizontal movement frame (756) is inserted and penetrates the injection body (751) horizontally so that four of them are perpendicular to each other on the same plane, and is closely seated on the “+”-shaped rotor (755) in the hollow groove (752), and as the “+”-shaped rotor (755) rotates, each of them is horizontally moved simultaneously in a direction away from the rotation column (753) or approaching the rotation column (753) by the “+”-shaped rotor (755).

[0810] That is, the horizontal movement frame (756) can be moved horizontally in a direction away from the rotation column (753) as it is pressed against the end of each branch of the “+”-shaped rotor (755) and in a direction approaching the rotation column (753) as it is pressed against the corner between the branches of the “+”-shaped rotor (755).

[0811] The curved cover (757) is formed by roundly bending a flat plate, and is supported by a cover support spring (758) and installed at each front end of a plurality of horizontally moving frames (756) to cover the injection body (751), and forms a screw thread along the outward surface to engage with the screw thread of the inward surface of the rotation guide groove (740).

[0812] That is, the curved cover (757) moves away from the rotation pillar (753) as the horizontal movement frame (756) is pressed against the ends of each branch of the “+”-shaped rotor (755) and engages with the threads on the inward surface of the rotation guide groove (740), and moves horizontally in a direction approaching the rotation pillar (753) as the horizontal movement frame (756) is pressed against the corners between the branches of the “+”-shaped rotor (755) so that it can be separated from the threads on the inward surface of the rotation guide groove (740) along the outward surface.

[0813] The cover support spring (758) is installed between the curved cover (757) and the injection body (751) and pulls the curved cover (757) toward the injection body (751).

[0814] The rotary injection unit (750) having the configuration described above may further include a first magnetic body (M1), a second magnetic body (M2), and a magnetic switch (759).

[0815] The first magnetic body (M1) is installed on the inside of the curved cover (757) and forms a magnetism of the “N” pole or the “S” pole by the magnetic switch (759).

[0816] The second magnetic body (M2) is formed in a circular ring shape along the inner side of the rotation guide groove (740) facing the first magnetic body (M1), and forms a magnetism of “N” pole or “S” pole by the magnetic switch (759).

[0817] The magnetic switch (759) switches the magnetism of the first magnetic body (M1) and the second magnetic body (M2) to the “N” pole or the “S” pole to induce the curved cover (757) to be fastened to the inside of the rotation guide groove (740) or to be separated from the inside of the rotation guide groove (740).

[0818] The rotary injection unit (750) having the configuration described above can effectively and precisely achieve adhesion or separation with the inward surface of the rotary guide groove (740).

[0819] Fig. 76 is a drawing showing the injection nozzle of Fig. 73.

[0820] Referring to FIG. 76, the injection nozzle (770) includes a nozzle installation groove (771), an elastic cover (772), and a plurality of nozzles (773).

[0821] The nozzle installation groove (771) is formed by recessing into the front end of the rotating injection unit (750).

[0822] The elastic cover (772) is made of an elastic material that can be expanded or contracted and is installed to cover the front opening of the nozzle installation groove (771). As a fluid, such as water or oil, is supplied to the nozzle installation groove (771), the elastic cover expands into a hemispherical shape by hydraulic pressure and returns to a flat shape as the fluid is discharged from the nozzle installation groove (771).

[0823] A plurality of nozzles (773) are installed radially along the elastic cover (772) to spray compressed air. When the elastic cover (772) is flat, the compressed air is sprayed in a direction perpendicular to the elastic cover (772), and the spraying direction of the compressed air changes as the elastic cover (772) expands.

[0824] The spray nozzle (770) having the configuration described above can improve the efficiency of removing foreign substances by varying and precisely changing the spray area of ​​compressed air sprayed through the nozzle (773) as the elastic cover (772) contracts as shown in (a) of FIG. 76 or expands as shown in (b) of FIG. 76.

[0825] FIG. 77 is a schematic diagram illustrating a configuration of a vehicle seat automatic docking and inspection system according to one embodiment of the present invention.

[0826] Referring to FIG. 77, a vehicle seat automatic docking and inspection system (10) according to one embodiment of the present invention includes a seat tray (100), a main frame (200), a forward driving unit (300), a first story connector (400), and a seat inspection unit (700).

[0827] The seat tray (100) is electrically connected to the vehicle seat (S) after the vehicle seat (S) is placed thereon, transmits and receives signals, and moves along the automobile production line (L).

[0828] The main frame (200) is installed on one side of the automobile production line (L) and supports the forward driving unit (300).

[0829] In one embodiment, the main frame (200) is configured with a profile frame to ensure lightness and durability, and may be configured with aluminum and a steel cover and bracket, etc.

[0830] The forward driving unit (300) is installed on the top of the main frame (200), and when the sheet tray (100) approaches, it is driven to move forward in the direction of the sheet tray (100).

[0831] The first story connector (400) is installed at the front end of the forward driving unit (300) and is connected to the second story connector (500) provided on the seat tray (100) to transmit and receive signals with the vehicle seat (S) by moving forward together with the forward driving unit (300).

[0832] The seat inspection unit (700) performs an inspection of the vehicle seat (S) through the seat information of the vehicle seat (S) transmitted through the first story connector (400).

[0833] In one embodiment, the seat inspection unit (700) can use the seat information of the vehicle seat (S) transmitted from the vehicle seat (S) through the first story connector (400) to inspect whether at least one or more vehicle parts among folding / unfolding, position movement, height movement, cushion angle, and lumbar support of the vehicle seat (S) are defective.

[0834] In one embodiment, the seat inspection unit (700) stores all inspection results for each vehicle part (i.e., any one of folding / unfolding, position movement, height movement, seat angle, and lumbar support) in a database, and can derive a failure correlation for each vehicle part from the accumulated database.

[0835] In one embodiment, the seat inspection unit (700) can determine that a vehicle seat (S) is faulty if the failure correlation between two vehicle parts is greater than a certain value, and if one part is within the normal value range but the other part is outside the normal value range or is at the boundary of the normal value range.

[0836] For example, the sheet inspection unit (700) can determine that part A is faulty if the failure correlation between part A and part B is above a certain level, even if part B is abnormal or is at the boundary of the normal range, even if part A is within the normal range.

[0837] In one embodiment, the seat inspection unit (700) can determine whether the vehicle seat (S) is faulty based on the result of whether the remaining parts are normal when one part and the other part are at the boundary of the normal value range in the correlation between two or more vehicle parts.

[0838] For example, the seat inspection unit (700) can determine whether the vehicle seat (S) is faulty based on the result of the C part when the A and B parts are within the boundary range in a correlation of two or more parts (part A-part B and part A-part C) (i.e., if the C part is within the normal range, the vehicle seat (S) is determined to be normal, if the C part is outside the normal range, the vehicle seat (S) is determined to be faulty, etc.).

[0839] The vehicle seat automatic docking and inspection system (10) according to one embodiment of the present invention having the configuration described above can induce accurate docking of a connector for inspection of a vehicle seat and a terminal of a seat tray moving along an automobile production line through vision inspection, and can also prevent damage to the device due to inaccurate docking.

[0844] The “H” shaped frame (230) is formed in an “H” shape and is fixedly installed on the upper side of the base plate (220), and vertical sliding grooves (231) are formed along the outward surfaces on both sides.

[0845] In one embodiment, the "H" shaped frame (230) may have vertical sliding grooves (231) formed along the outward faces of the one and the other vertical surfaces on which the first adjustment cover (240) and the second adjustment cover (250) are mounted so that the first adjustment cover (240) and the second adjustment cover (250) can be mounted and moved in the up and down direction, respectively.

[0846] The first adjustment cover (240) is installed in a manner that allows sliding movement in the up-and-down direction by interlocking with the outwardly facing surface of one vertical surface of the “H”-shaped frame (230), i.e., the vertical sliding groove (231), and supports the installation plate (260).

[0847] The second adjustment cover (250) is installed in a manner that allows sliding movement in the up-and-down direction by interlocking with the outward facing surface of the other vertical surface of the “H”-shaped frame (230), i.e., the vertical sliding groove (231), and supports the installation plate (260).

[0848] The installation plate (260) is formed in a flat shape and is supported by a first adjustment cover (240) and a second adjustment cover (250), and a forward driving unit (300) is installed on the upper side.

[0849] In one embodiment, the main frame (200) may further include a height adjustment cylinder (270).

[0850] The height adjustment cylinder (270) is installed between the horizontal stop surface of the “H” shaped frame (230) and the installation plate (260) to support the installation plate (260) and at the same time, is driven to extend or contract in the vertical direction in response to the docking position of the first story connector (400) to adjust the height of the installation plate (260).

[0851] The main frame (200) having the configuration described above can install a forward driving unit (300) and precisely move the forward driving unit (300) up and down to induce the first story connector (400) to be accurately docked to the second story connector (500).

[0852] Figure 79 is a drawing showing the forward driving unit of Figure 77.

[0853] Referring to FIG. 79, the forward drive unit (300) includes a drive unit casing (310), a horizontal movement cylinder (320), and two horizontal guide bars (330).

[0854] The drive unit casing (310) is installed on the upper side of the installation plate (260), and components such as a horizontal movement cylinder (320) and two horizontal guide bars (330) are installed.

[0855] The horizontal movement cylinder (320) is a pneumatic cylinder, installed inside the driving unit casing (310), and the front end exposed from the driving unit casing (310) is installed at the rear end of the first storage connector (400), and moves the first storage connector (400) in a horizontal direction forward and backward as it is driven to extend or contract, thereby performing docking between the first storage connector (400) and the second storage connector (500).

[0856] Two horizontal guide bars (330) are installed on one side and the other side of the rear end of the first story connector (400) with the horizontal movement cylinder (320) between them, and are installed so as to penetrate the driving unit casing (310) in the front-back direction, thereby guiding the horizontal movement of the first story connector (400) in the front-back direction.

[0857] The forward driving unit (300) having the configuration described above can precisely move the first story connector (400) in the forward and backward direction so that the first story connector (400) can be accurately connected to the second story connector (500).

[0858] FIGS. 80 and 81 are drawings showing the first story connector of FIG. 77.

[0859] Referring to FIGS. 80 and 81, the first story connector (400) includes a connector casing (410), a first connector plate (420), a second connector plate (430), two plate supports (440), and two fastening guide bars (450).

[0860] The connector casing (410) is supported by two horizontal guide bars (330) at the front of the drive casing (310), and moves horizontally by a horizontal movement cylinder (320) while moving the first connector plate (420) installed at the front end in the forward and backward direction.

[0861] The first connector plate (420) is fixedly installed at the front end of the connector casing (410), and connector pins (P1) for transmitting and receiving electric signals are installed in a row.

[0862] The second connector plate (430) is supported on both sides by two plate supports (440) and is placed in front of the first connector plate (420), and connector pins (P2) for transmitting electric signals between the connector pins of the first connector plate (420) and the second storage connector (500) provided on the sheet tray (100) are installed in a row.

[0863] Two plate supports (440) are installed on one side and the other side of the first connector plate (420), respectively, to support one side and the other side of the second connector plate (430).

[0864] In one embodiment, the plate support (440) may include a support body (441) and a first plate connecting portion (442).

[0865] The support body (441) is fixedly installed so as to be perpendicular to the first connector plate (420), and a first plate connecting portion (442) is installed at the front end.

[0866] The first plate connecting portion (442) is installed at the front end of the support body (441) and is connected to the second connector plate (430) to support the second connector plate (430).

[0867] Two fastening guide bars (450) are installed on one side and the other side of the front end of the second connector plate (430), respectively, and are inserted through the bar insertion groove (520) to guide fastening of the second connector plate (430) and the second storage connector (500) provided on the sheet tray (100).

[0868] The first story connector (400) having the configuration described above may further include a vision recognition unit (not shown in the drawing for convenience of explanation), an insertion pressure measurement unit (not shown in the drawing for convenience of explanation), and a vibration module (not shown in the drawing for convenience of explanation).

[0869] The vision recognition unit, as a vision recognition device, performs primary vision recognition on the insertion position of the fastening guide bar (450) before the fastening guide bar (450) is prepared for insertion into the bar insertion groove (520), and performs secondary vision recognition on the insertion position of the bar insertion groove (520) before the fastening guide bar (450) is prepared for insertion into the bar insertion groove (520).

[0870] The insertion pressure measuring unit measures the insertion pressure of the fastening guide bar (450) inserted into the bar insertion groove (520).

[0871] That is, if the insertion pressure measured by the insertion pressure measuring unit exceeds the set value, it is determined that the fastening guide bar (450) is not normally inserted into the bar insertion groove (520), and thus the insertion of the fastening guide bar (450) is stopped, thereby preventing a failure or damage to the system.

[0872] In one embodiment, the first story connector (400) may retract the first connector plate (420) when an insertion pressure exceeding a set pressure is transmitted from the insertion pressure measuring unit, and then attempt to re-insert the fastening guide bar (450) after realigning the position of the first connector plate (420).

[0873] The vibration module can prevent system failure or damage by generating micro-vibrations in the fastening guide bar (450) to reduce the insertion pressure when the fastening guide bar (450) is inserted.

[0874] Figure 82 is a drawing showing the first plate connection of Figure 81.

[0875] Referring to FIG. 82, the first plate connecting portion (442) includes a first plate support bolt (4421), a first plate cover (4422), and a second plate cover (4423).

[0884] Two bar insertion grooves (520) are formed on one side and the other side of the third connector plate (510) facing the fastening guide bar (450) so that the third connector plate (510) and the second connector plate (430) can be engaged as the fastening guide bar (450) is inserted.

[0885] In one embodiment, the bar insertion groove (520) may be formed with an inner diameter corresponding to the diameter of the fastening guide bar (450), but may be formed in a cone shape with the inner diameter gradually decreasing as the opening goes inward so as to induce the fastening guide bar (450) to be seated.

[0890] Here, it is preferable that the second anchoring hole (H2) be formed with an inner diameter larger than the outer diameter of the second plate support bolt (531) so that the second plate support bolt (531) can move within (e.g., 1 to 5 mm).

[0891] The third plate cover (532) is formed at the rear end of the second plate support bolt (531) in the shape of a disk with a diameter larger than the inner diameter of the second fixing hole (H2) and is fixed to the rear of the second plate support bolt (531).

[0896] Here, the sheet tray (100), main frame (200), forward drive unit (300), and first story connector (400) are the same as the components of Fig. 77, so their descriptions are omitted to avoid duplication of explanation.

[0897] The seat cleaner (600) is installed at least once along the automobile production line (L) and removes foreign substances such as dust attached to the vehicle seat (S) moving by the seat tray (100) by spraying compressed air.

[0899] The installation housing (610) is configured in a polygonal frame shape so that a vehicle seat (S) moving by a seat tray (100) can pass through the inside, and is installed in an automobile production line (L), and components such as a rear cleaning unit (620) and a front cleaning unit (630) are installed.

[0900] The rear cleaning unit (620) is installed on the inward surface of the vertical surface (611) formed at the rear end of the installation housing (610) facing the rear end of the vehicle seat (S) and sprays compressed air toward the rear end of the vehicle seat (S) to clean foreign substances such as dust.

[0901] The front cleaning unit (630) is installed on the inward surface of the front slope (612) of the installation housing (610) facing both the front of the backrest and the upper side of the cushion that constitute the vehicle seat (S) and sprays compressed air toward the front of the backrest and the upper side of the cushion to clean foreign substances such as dust.

[0902] In one embodiment, the shear cleaner (630) may include an inclined rail (631), a slider (632), a rail arm (633), and a cleaning module (700).

[0903] Here, the rear cleaning unit (620) has the same configuration as the front cleaning unit (630) described below, and the inclined rail (631), slider (632), rail arm (633), and cleaning module (700) of the front cleaning unit (630) can be applied in the same manner. Therefore, the description thereof will be omitted to avoid duplication of explanation.

[0904]

[0905] The inclined rail (631) is formed to extend along the inward surface of the front inclined surface (612) of the installation housing (610) so that the slider (632) can be interlocked and installed to slide.

[0906] The slider (632) is installed in a manner that allows sliding movement on the inclined rail (631), and moves the rail arm (633) in response to the cleaning position.

[0907] Rail arms (633) are installed in multiple numbers so that they can be mutually rotated sequentially from the front end of the slider (632) to form multiple connecting joints (J), and each connecting joint is rotated so that it can face parallel to the backrest and cushion of the vehicle seat (S).

[0908] The cleaning module (700) is installed at least once on each lower surface of a plurality of rail arms (633) facing the vehicle seat (S), and performs cleaning by spraying compressed air toward the front of the backrest or the upper side of the cushion to remove foreign substances.

[0909] A vehicle seat automatic docking and inspection system (20) according to another embodiment of the present invention having the configuration described above can improve the manufacturing quality of the vehicle seat (S) without stopping the manufacturing process by removing foreign substances such as dust attached to the vehicle seat (S) without stopping during the movement of the vehicle seat (S).

[0910] Figures 86 and 87 are drawings showing the cleaning module of Figure 85.

[0911] Referring to FIGS. 86 and 87, the cleaning module (700) includes a rail home (710), a module slider (720), a module body (730), a rotation guide home (740), a rotation spray unit (750), an actuator (760), and a spray nozzle (770).

[0912] The rail home (710) is formed to extend along the bottom surface of the rail arm (633) so that the module slider (720) can be engaged to enable sliding movement.

[0913] The module slider (720) slides along the rail home (710) to move the module body (730) to the compressed air injection position.

[0914] The module body (730) is installed at the bottom of the module slider (720), and components such as a rotation guide groove (740), a rotation injection unit (750), an actuator (760), and an injection nozzle (770) are installed.

[0915] The rotation guide groove (740) is formed to extend along the inside of the module body (730) while forming an opening at the bottom of the module body (730) so that the rotation injection part (750) can be engaged, inserted, or exposed, and forms a screw thread along the inner surface.

[0916] The rotary injection unit (750) is formed in a cylindrical shape and is installed in a manner that it is connected to the inner surface of the rotary guide groove (740) so that it can rotate in the internal space of the rotary guide groove (740), and is inserted into the inside of the rotary guide groove (740) or exposed from the rotary guide groove (740) as it rotates in the forward or reverse direction.

[0917] In one embodiment, the rotary injector (750) moves along the rotary injector groove (740) while rotating as the actuator (760) extends or contracts when the curved cover (757) described below is closely seated on the inner surface of the rotary injector groove (740) as it moves away from the injector body (751), and when the curved cover (757) is closely seated on the injector body (751) and separated from the inner surface of the rotary injector groove (740), the actuator (760) can move along the rotary injector groove (740) in a straight direction without rotating as it extends or contracts.

[0918] In one embodiment, the rotating injection unit (750) can reduce the spray angle of compressed air sprayed from the cleaning module (700) when inserted into the inside of the rail home (710) as shown in (a) of FIG. 87, thereby reducing the cleaning area by the compressed air, and can increase the spray angle of compressed air sprayed from the cleaning module (700) that moves forward toward the front end of the rail home (710) as shown in (b) of FIG. 87, thereby increasing the cleaning area by the compressed air.

[0919] The actuator (760) is installed inside the rotation guide groove (740) to support the rear end of the rotation injection unit (750), and is driven to extend or contract to move the rotation injection unit (750) forward or backward.

[0920] The injection nozzle (770) is installed along the front end of the rotating injection unit (750) and removes foreign substances by spraying compressed air supplied from a compressed air supply device installed externally (not shown in the drawing for convenience of explanation).

[0921] The cleaning module (700) having the configuration described above can improve the efficiency of removing foreign substances by inducing rotation of compressed air sprayed from the spray nozzle (770) or varying the spray angle of the compressed air by rotating the module body (730).

[0922] Figures 88 and 89 are drawings showing the rotating injector of Figure 87.

[0923] Referring to FIGS. 88 and 89, the rotary injector (750) includes an injector body (751), a hollow groove (752), a rotary column (753), a column driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), and a cover support spring (758).

[0924] The injection unit body (751) has a cylindrical shape in which an injection nozzle (770) is installed along a front end exposed from a rotation guide groove (740), and is installed so as to be rotatably connected to the front end of an actuator (760), and is configured with a hollow groove (752), a rotation pillar (753), a pillar driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), a first magnetic body (M1), a second magnetic body (M2), a cover support spring (758), and a magnetic switch (759).

[0925] The hollow groove (752) is formed hollow along the inside of the injection body (751) while the rotating column (753) is positioned and the “+” shaped rotor (755) is positioned to form sufficient space for rotation.

[0926] The rotating column (753) is positioned so as to be rotatable along the center of the internal space of the hollow groove (752), and is driven to rotate by the column driving motor (754) to rotate the “+”-shaped rotor (755) together.

[0927] The pillar drive motor (754) is installed upright on the upper side of the hollow groove (752), and the upper end of the rotary pillar (753) is installed on the drive shaft by axial coupling to drive the rotary pillar to rotate in the forward or reverse direction.

[0928] The "+" type rotor (755) is formed in a "+" shape with each of the four ends rounded, and is installed in multiple pieces by axial coupling at regular intervals along the rotation column (753) so that it rotates together as the rotation column rotates and supports each end of the horizontal movement frame (756).

[0929] The horizontal movement frame (756) is inserted and penetrates the injection body (751) horizontally so that four of them are perpendicular to each other on the same plane, and is closely seated on the “+”-shaped rotor (755) in the hollow groove (752), and as the “+”-shaped rotor (755) rotates, each of them is horizontally moved simultaneously in a direction away from the rotation column (753) or approaching the rotation column (753) by the “+”-shaped rotor (755).

[0930] That is, the horizontal movement frame (756) can be moved horizontally in a direction away from the rotation column (753) as it is pressed against the end of each branch of the “+”-shaped rotor (755) and in a direction approaching the rotation column (753) as it is pressed against the corner between the branches of the “+”-shaped rotor (755).

[0931] The curved cover (757) is formed by roundly bending a flat plate, and is supported by a cover support spring (758) and installed at each front end of a plurality of horizontally moving frames (756) to cover the injection body (751), and forms a screw thread along the outward surface to engage with the screw thread of the inward surface of the rotation guide groove (740).

[0932] That is, the curved cover (757) moves away from the rotation pillar (753) as the horizontal movement frame (756) is pressed against the ends of each branch of the “+”-shaped rotor (755) and engages with the threads on the inward surface of the rotation guide groove (740), and moves horizontally in a direction approaching the rotation pillar (753) as the horizontal movement frame (756) is pressed against the corners between the branches of the “+”-shaped rotor (755) so that it can be separated from the threads on the inward surface of the rotation guide groove (740) along the outward surface.

[0933] The cover support spring (758) is installed between the curved cover (757) and the injection body (751) and pulls the curved cover (757) toward the injection body (751).

[0934] The rotary injection unit (750) having the configuration described above may further include a first magnetic body (M1), a second magnetic body (M2), and a magnetic switch (759).

[0935] The first magnetic body (M1) is installed on the inside of the curved cover (757) and forms a magnetism of the “N” pole or the “S” pole by the magnetic switch (759).

[0936] The second magnetic body (M2) is formed in a circular ring shape along the inner side of the rotation guide groove (740) facing the first magnetic body (M1), and forms a magnetism of “N” pole or “S” pole by the magnetic switch (759).

[0937] The magnetic switch (759) switches the magnetism of the first magnetic body (M1) and the second magnetic body (M2) to the “N” pole or the “S” pole to induce the curved cover (757) to be fastened to the inside of the rotation guide groove (740) or to be separated from the inside of the rotation guide groove (740).

[0938] The rotary injection unit (750) having the configuration described above can effectively and precisely achieve adhesion or separation with the inward surface of the rotary guide groove (740).

[0939] Fig. 90 is a drawing showing the injection nozzle of Fig. 87.

[0940] Referring to FIG. 90, the injection nozzle (770) includes a nozzle installation groove (771), an elastic cover (772), and a plurality of nozzles (773).

[0941] The nozzle installation groove (771) is formed by recessing into the front end of the rotating injection unit (750).

[0942] The elastic cover (772) is made of an elastic material that can be expanded or contracted and is installed to cover the front opening of the nozzle installation groove (771). As a fluid, such as water or oil, is supplied to the nozzle installation groove (771), the elastic cover expands into a hemispherical shape by hydraulic pressure and returns to a flat shape as the fluid is discharged from the nozzle installation groove (771).

[0943] A plurality of nozzles (773) are installed radially along the elastic cover (772) to spray compressed air. When the elastic cover (772) is flat, the compressed air is sprayed in a direction perpendicular to the elastic cover (772), and the spraying direction of the compressed air changes as the elastic cover (772) expands.

[0944] The spray nozzle (770) having the configuration described above can improve the efficiency of removing foreign substances by varying and precisely changing the spray area of ​​compressed air sprayed through the nozzle (773) as the elastic cover (772) contracts as shown in (a) of FIG. 90 or expands as shown in (b) of FIG. 90.

[0945] FIG. 91 is a schematic diagram illustrating a configuration of a gap measurement and failure prediction system for a vehicle seat according to one embodiment of the present invention.

[0946] Referring to FIG. 91, a vehicle seat gap measurement and failure prediction system (10) according to one embodiment of the present invention includes a main frame (100), a rail frame (200), an inspection unit (300), a good product reading unit (400), and a failure prediction unit (800).

[0947] The main frame (100) is installed on one side of an automobile production line (L) for moving a seat tray on which a vehicle seat (S) (e.g., a third-row seat of a vehicle) on which a first sheet (S1) and a second sheet (S2) are installed in close contact is installed.

[0948] In one embodiment, the main frame (100) is configured with a high-strength profile to improve the structural stability of the equipment, and a reinforcing member (110) is installed between the main frame (100) and the rail frame (200) to structurally reinforce the shaking of the protrudingly installed rail frame (200).

[0949] The rail frame (200) is installed horizontally while looking at the automobile production line (L) from the top of the main frame (100), and components such as the inspection unit (300) are installed.

[0950] The inspection unit (300) is installed in a sliding manner in a rail frame (200), moves backward along the rail frame (200) to approach the main frame (100) when the vehicle seat (S) moves, and moves forward along the rail frame (200) to face the measurement position of the vehicle seat (S) when measuring the gap of the vehicle seat (S), and senses the gap between the first sheet (S1) and the second sheet (S2) (i.e., the step difference between the first sheet (S1) and the second sheet (S2).

[0951] In one embodiment, the inspection unit (300) can sense the gap between the first seat (S1) and the second seat (S2) while looking downward after moving forward before tilting the vehicle seat (S) as shown in FIG. 92, and can sense the gap between the first seat (S1) and the second seat (S2) while looking forward after being positioned close to the main frame (100) after tilting the vehicle seat (S) as shown in FIG. 93.

[0952] In one embodiment, the inspection unit (300) can sense the gap between the first sheet (S1) and the second sheet (S2) in real time while tracking the folding or unfolding process of each of the first sheet (S1) and the second sheet (S2).

[0953] In one embodiment, the inspection unit (300) can sense the gap between the first sheet (S1) and the second sheet (S2) by analyzing the speed difference or displacement difference during the folding or unfolding process of the first sheet (S1) and the second sheet (S2), respectively.

[0954] In one embodiment, the inspection unit (300) can analyze the folding or unfolding speed of the first sheet (S1) and the second sheet (S2) by analyzing the position of an individual sheet, either the first sheet (S1) or the second sheet (S2).

[0955] The quality reading unit (400) uses sensing information transmitted from the inspection unit (300) to read whether the vehicle seat (S) is quality by determining whether the gap between the first sheet (S1) and the second sheet (S2) is within the error range.

[0956] The failure prediction unit (800) predicts the possibility of failure of the vehicle seat (S) through sensing information transmitted from the inspection unit (300) or artificial intelligence analysis.

[0957] In one embodiment, the inspection unit (300) can sense the gap at various angles during the folding or unfolding process of the first sheet (S1) and the second sheet (S2), even when the overall folding or unfolding speed of the first sheet (S1) or the second sheet (S2) is within a normal range.

[0958] In one embodiment, the failure prediction unit (800) may determine that there is a possibility of a defect in the drive system or gear unit of the vehicle seat (S) when a partial gap difference or speed difference occurs during the folding or unfolding process of the first sheet (S1) or the second sheet (S2).

[0959] In one embodiment, the failure prediction unit (800) can build an artificial intelligence-based vehicle seat (S) failure prediction model that is trained to predict the possibility of failure of the vehicle seat (S) by using as input information abnormal speed data and abnormal gap data for each operating position when the vehicle seat (S) is folded or unfolded, which are transmitted from the inspection unit (300).

[0960] In one embodiment, the failure prediction unit (800) can predict the possibility of failure of the vehicle seat (S) when the intensity of vibration generated when folding or unfolding the vehicle seat (S) is greater than a preset vibration value through vibration analysis using vibration information included in the sensing information transmitted from the inspection unit (300), or can predict the possibility of failure of the vehicle seat (S) through analysis of the amount of change in vibration generated when folding or unfolding the vehicle seat (S).

[0961] A vehicle seat gap measurement and failure prediction system (10) according to one embodiment of the present invention having a configuration as described above can predict the possibility of failure of a vehicle seat by measuring the gap between two seats in a vehicle seat manufactured by closely arranging the two seats and by using sensing information or artificial intelligence analysis generated while measuring the gap.

[0962] Fig. 94 is a drawing showing the rail frame of Fig. 91.

[0963] Referring to FIG. 94, the rail frame (200) includes a horizontal frame (210), a sliding hole (220), a servo motor (230), and a ball screw (240).

[0964] The horizontal frame (210) is installed at the top of the main frame (100) while looking at the automobile production line (L) at a right angle to the direction of movement of the vehicle seat (S), and components such as a sliding hole (220), a servo motor (230), and a ball screw (240) are installed.

[0965] The sliding hole (220) is formed to extend in the longitudinal direction along the break of the horizontal frame (210) so that the upper part of the inspection unit (300) can be settled and moved, and components such as the sliding hole (220), servo motor (230), and ball screw (240) are installed.

[0966] The servo motor (230) is installed on the upper rear side of the horizontal frame (210) and drives the ball screw (240) to rotate in the forward or reverse direction.

[0967] The ball screw (240) is installed by shaft coupling to the drive shaft of the servo motor (230) and is positioned along the upper side of the sliding hole, and is connected and interlocked with the upper end of the inspection section (300) by bolt coupling, and is driven to rotate in the forward or reverse direction by the servo motor (230) to move the inspection section (300) forward or backward along the sliding hole (220).

[0968] The rail frame (200) having the configuration described above is installed while facing the production line (L) to stably support the inspection unit (300) and precisely slide the inspection unit (300) in response to the sensing position of the inspection unit (300).

[0969] Figure 95 is a drawing showing the inspection section of Figure 91.

[0970] Referring to FIG. 95, the inspection unit (300) includes a horizontal slider (310), a vertical body (320), a sensor casing (330), a gap measurement sensor (340), and a bundle connecting unit (350).

[0971] The horizontal slider (310) is installed in the sliding hole (220) and is interlocked with the ball screw (240) by a bolt and nut combination, and moves along the sliding hole (220) as the ball screw (240) rotates in the forward or reverse direction.

[0972] In one embodiment, the horizontal slider (310) may include a connecting nut (311) and a nut support (312), as illustrated in FIG. 94.

[0973] The connecting nut (311) is installed by being interlocked with the ball screw (240) through a bolt nut combination, and moves the nut support (312) while moving along the ball screw (240) as the ball screw (240) rotates in the forward or reverse direction.

[0974] The nut support (312) is installed at the top of the vertical body (320) and is mounted on the connecting nut (311), and moves along the sliding hole (220) as the connecting nut (311) moves.

[0975] A horizontal slider (310) having a configuration as described above may further include a guide rail (313) and a guide (314).

[0976] The guide rail (313) is installed along one side and the other side of the downward surface of the horizontal frame (210) with a sliding hole (220) between them so that the guide (314) can be interlocked, connected, and moved.

[0977] The guide (314) is installed on one side and the other side of the upper part of the vertical body (320) and is connected to the guide rail (313) so as to slide along the guide rail (313) and guide the horizontal movement of the vertical body (320).

[0978] The vertical body (320) is installed on the lower side of the horizontal slider (310).

[0979] The sensor casing (330) is placed on the lower side of the vertical body (320).

[0980] The gap measurement sensor (340) is installed in the sensor casing (330) and senses the gap between the first sheet (S1) and the second sheet (S2).

[0981] In one embodiment, the gap measurement sensor (340) can sense the gap between the first sheet (S1) and the second sheet (S2) while simultaneously moving together while tracking the first sheet (S1) and the second sheet (S2) when the first sheet (S1) or the second sheet (S2) folds or unfolds.

[0982] In one embodiment, the gap measurement sensor (340) is installed on the lower side of the sensor casing (330) as illustrated in FIG. 92 and can sense the gap between the first sheet (S1) and the second sheet (S2) in a folded state on the lower side.

[0983] In one embodiment, the gap measurement sensor (340) can sense the gap between the first sheet (S1) and the second sheet (S2) in an unfolded state at the front when the mounting arm (354) is rotationally driven so that the lower side of the sensor casing (330) faces forward, as illustrated in FIG. 93.

[0984] The bundle connecting portion (350) interconnects the vertical body (320) and the sensor casing (330).

[0985] The inspection unit (300) having the configuration described above can precisely change the angle for sensing as well as precisely move the gap measurement sensor (340) performing sensing in the forward and backward directions and up and down directions.

[0986] That is, the inspection unit (300) having the configuration as described above can, as shown in FIG. 92, in the case before tilting of the vehicle seat, the horizontal slider (310) moves forward along the rail frame (200), and then moves the sensor casing (330) downward, and at the same time, tilt the gap measurement sensor (340) so that it faces downward, and then perform sensing. As shown in FIG. 93, in the case after tilting of the vehicle seat, the horizontal slider (310) moves backward along the rail frame (200) to move close to the main frame (100), and then moves the sensor casing (330) upward, and at the same time, tilt the gap measurement sensor (340) so that it faces forward, and then perform sensing. Therefore, the inconvenience of having to provide various types of sensing devices depending on whether the vehicle seat is tilted can be solved.

[0987] Figures 96 and 97 are drawings showing the bundle connection of Figure 95.

[0988] Referring to FIGS. 96 and 97, the bundle connecting portion (350) includes a vertical cylinder (351), a connecting plate (352), a rotating cylinder (353), and a mounting arm (354).

[0989] The vertical cylinder (351) is installed on the lower side of the vertical body (320) and moves the connection plate (352) vertically in the up-and-down direction while driving the expansion or contraction in the up-and-down direction to move the gap measurement sensor (340) to the sensing position.

[0990] In one embodiment, the vertical cylinder (351) can be driven to contract and move the sensor casing (330) upward so that interference between the first sheet (S1) and the second sheet (S2) does not occur when the first sheet (S1) and the second sheet (S2) are folded or unfolded.

[0991] The connecting plate (352) moves up and down vertically by a vertical cylinder (351).

[0992] A rotating cylinder (353) is installed on one side of the connecting plate (352) and drives the mounting arm (354) to rotate.

[0993] The mounting arm (354) is installed by means of an axial coupling to the rotation axis of the rotation cylinder (353) to mount the sensor casing (330), and is rotationally driven by the rotation cylinder (353) to rotationally drive the sensor casing (330).

[0994] The bundle connecting part (350) having the configuration described above can enable precise sensing to be performed without being restricted by the sensing position of the vehicle seat by tilting the gap measuring sensor (340) in response to the sensing position of the gap measuring sensor (340) as well as in the vertical and vertical directions, as shown in FIG. 97.

[0995] FIG. 98 is a schematic diagram illustrating a configuration of a gap measurement and failure prediction system for a vehicle seat according to another embodiment of the present invention.

[0996] Referring to FIG. 98, a gap measurement and failure prediction system (20) of a vehicle seat according to another embodiment of the present invention includes a main frame (100), a rail frame (200), an inspection unit (300), a good product reading unit (400), and a calibration unit (500).

[0997] Here, the main frame (100), rail frame (200), inspection unit (300), and quality reading unit (400) are the same as the components of Fig. 91, so their descriptions are omitted to avoid duplication of explanation.

[0998] The calibration unit (500) is installed in the main frame (100) to perform sensing calibration of the inspection unit (300).

[0999] In one embodiment, it may include a connecting member (510), a horizontal plate (520), and a calibration block (530).

[1000] The connecting member (510) is installed on the main frame (100) facing the inspection unit (300) so that a horizontal plate (520) can be installed.

[1001] A horizontal plate (520) is installed at the front end of the connecting member (510) so that a calibration block (530) can be installed.

[1002] The calibration block (530) is installed on the top of the horizontal plate (520), and steps with a constant height difference are repeatedly formed along the top.

[1003] In one embodiment, the inspection unit (300) can perform calibration by detecting the line of the step of the calibration block (530), and perform sensing after the calibration is completed.

[1004] The gap measurement and failure prediction system (20) of a vehicle seat according to another embodiment of the present invention having the configuration described above can always ensure accurate sensing without the need for installing unnecessary devices by performing calibration by the system itself without separate calibration equipment.

[1005] FIG. 99 is a schematic diagram illustrating a configuration of a gap measurement and failure prediction system for a vehicle seat according to another embodiment of the present invention.

[1007] Here, the sheet tray (100), main frame (200), forward drive unit (300), and first story connector (400) are the same as the components of Fig. 91, so their descriptions are omitted to avoid duplication of explanation.

[1008] The seat cleaner (600) is installed at least once along the automobile production line (L) and removes foreign substances such as dust attached to the vehicle seat (S) moving by the seat tray (100) by spraying compressed air.

[1009] In one embodiment, the sheet cleaner (600) may include an installation housing (610), a rear cleaner (620), and a front cleaner (630).

[1010] The installation housing (610) is configured in a polygonal frame shape so that a vehicle seat (S) moving by a seat tray (100) can pass through the inside, and is installed in an automobile production line (L), and components such as a rear cleaning unit (620) and a front cleaning unit (630) are installed.

[1011] The rear cleaning unit (620) is installed on the inward surface of the vertical surface (611) formed at the rear end of the installation housing (610) facing the rear end of the vehicle seat (S) and sprays compressed air toward the rear end of the vehicle seat (S) to clean foreign substances such as dust.

[1012] The front cleaning unit (630) is installed on the inward surface of the front slope (612) of the installation housing (610) facing both the front of the backrest and the upper side of the cushion that constitute the vehicle seat (S) and sprays compressed air toward the front of the backrest and the upper side of the cushion to clean foreign substances such as dust.

[1013] In one embodiment, the shear cleaner (630) may include an inclined rail (631), a slider (632), a rail arm (633), and a cleaning module (700).

[1014] Here, the rear cleaning unit (620) has the same configuration as the front cleaning unit (630) described below, and the inclined rail (631), slider (632), rail arm (633), and cleaning module (700) of the front cleaning unit (630) can be applied in the same manner. Therefore, the description thereof will be omitted to avoid duplication of explanation.

[1015] The inclined rail (631) is formed to extend along the inward surface of the front inclined surface (612) of the installation housing (610) so that the slider (632) can be interlocked and installed to slide.

[1016] The slider (632) is installed in a manner that allows sliding movement on the inclined rail (631), and moves the rail arm (633) in response to the cleaning position.

[1017] Rail arms (633) are installed in multiple numbers so that they can be mutually rotated sequentially from the front end of the slider (632) to form multiple connecting joints (J), and each connecting joint is rotated so that it can face parallel to the backrest and cushion of the vehicle seat (S).

[1018] The cleaning module (700) is installed at least once on each lower surface of a plurality of rail arms (633) facing the vehicle seat (S), and performs cleaning by spraying compressed air toward the front of the backrest or the upper side of the cushion to remove foreign substances.

[1019] A gap measurement and failure prediction system (30) for a vehicle seat according to another embodiment of the present invention having the configuration described above can improve the manufacturing quality of a vehicle seat (S) without stopping the manufacturing process by removing foreign substances such as dust attached to the vehicle seat (S) without stopping during movement of the vehicle seat (S).

[1020] FIGS. 100 and 101 are drawings showing the cleaning module of FIG. 99.

[1021] Referring to FIGS. 100 and 101, the cleaning module (700) includes a rail home (710), a module slider (720), a module body (730), a rotation guide home (740), a rotation spray unit (750), an actuator (760), and a spray nozzle (770).

[1022] The rail home (710) is formed to extend along the bottom surface of the rail arm (633) so that the module slider (720) can be engaged to enable sliding movement.

[1023] The module slider (720) slides along the rail home (710) to move the module body (730) to the compressed air injection position.

[1024] The module body (730) is installed at the bottom of the module slider (720), and components such as a rotation guide groove (740), a rotation injection unit (750), an actuator (760), and an injection nozzle (770) are installed.

[1025] The rotation guide groove (740) is formed to extend along the inside of the module body (730) while forming an opening at the bottom of the module body (730) so that the rotation injection part (750) can be engaged, inserted, or exposed, and forms a screw thread along the inner surface.

[1026] The rotary injection unit (750) is formed in a cylindrical shape and is installed in a manner that it is connected to the inner surface of the rotary guide groove (740) so that it can rotate in the internal space of the rotary guide groove (740), and is inserted into the inside of the rotary guide groove (740) or exposed from the rotary guide groove (740) as it rotates in the forward or reverse direction.

[1027] In one embodiment, the rotary injector (750) moves along the rotary injector groove (740) while rotating as the actuator (760) extends or contracts when the curved cover (757) described below is closely seated on the inner surface of the rotary injector groove (740) as it moves away from the injector body (751), and when the curved cover (757) is closely seated on the injector body (751) and separated from the inner surface of the rotary injector groove (740), the actuator (760) can move along the rotary injector groove (740) in a straight direction without rotating as it extends or contracts.

[1028] In one embodiment, the rotating injection unit (750) can reduce the spray angle of compressed air sprayed from the cleaning module (700) when inserted into the inside of the rail home (710) as shown in (a) of FIG. 101, thereby reducing the cleaning area by the compressed air, and can increase the spray angle of compressed air sprayed from the cleaning module (700) that moves forward toward the front end of the rail home (710) as shown in (b) of FIG. 101, thereby increasing the cleaning area by the compressed air.

[1029] The actuator (760) is installed inside the rotation guide groove (740) to support the rear end of the rotation injection unit (750), and is driven to extend or contract to move the rotation injection unit (750) forward or backward.

[1030] The injection nozzle (770) is installed along the front end of the rotating injection unit (750) and removes foreign substances by spraying compressed air supplied from a compressed air supply device installed externally (not shown in the drawing for convenience of explanation).

[1031] The cleaning module (700) having the configuration described above can improve the efficiency of removing foreign substances by inducing rotation of compressed air sprayed from the spray nozzle (770) or varying the spray angle of the compressed air by rotating the module body (730).

[1032] Figures 102 and 103 are drawings showing the rotating injector of Figure 101.

[1033] Referring to FIGS. 102 and 103, the rotary injector (750) includes an injector body (751), a hollow groove (752), a rotary column (753), a column driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), and a cover support spring (758).

[1034] The injection unit body (751) has a cylindrical shape in which an injection nozzle (770) is installed along a front end exposed from a rotation guide groove (740), and is installed so as to be rotatably connected to the front end of an actuator (760), and is configured with a hollow groove (752), a rotation pillar (753), a pillar driving motor (754), a “+”-shaped rotor (755), a horizontal movement frame (756), a curved cover (757), a first magnetic body (M1), a second magnetic body (M2), a cover support spring (758), and a magnetic switch (759).

[1035] The hollow groove (752) is formed hollow along the inside of the injection body (751) while the rotating column (753) is positioned and the “+” shaped rotor (755) is positioned to form sufficient space for rotation.

[1036] The rotating column (753) is positioned so as to be rotatable along the center of the internal space of the hollow groove (752), and is driven to rotate by the column driving motor (754) to rotate the “+”-shaped rotor (755) together.

[1037] The pillar drive motor (754) is installed upright on the upper side of the hollow groove (752), and the upper end of the rotary pillar (753) is installed on the drive shaft by axial coupling to drive the rotary pillar to rotate in the forward or reverse direction.

[1038] The "+" type rotor (755) is formed in a "+" shape with each of the four ends rounded, and is installed in multiple pieces by axial coupling at regular intervals along the rotation column (753) so that it rotates together as the rotation column rotates and supports each end of the horizontal movement frame (756).

[1039] The horizontal movement frame (756) is inserted and penetrates the injection body (751) horizontally so that four of them are perpendicular to each other on the same plane, and is closely seated on the “+”-shaped rotor (755) in the hollow groove (752), and as the “+”-shaped rotor (755) rotates, each of them is horizontally moved simultaneously in a direction away from the rotation column (753) or approaching the rotation column (753) by the “+”-shaped rotor (755).

[1040] That is, the horizontal movement frame (756) can be moved horizontally in a direction away from the rotation column (753) as it is pressed against the end of each branch of the “+”-shaped rotor (755) and in a direction approaching the rotation column (753) as it is pressed against the corner between the branches of the “+”-shaped rotor (755).

[1041] The curved cover (757) is formed by roundly bending a flat plate, and is supported by a cover support spring (758) and installed at each front end of a plurality of horizontally moving frames (756) to cover the injection body (751), and forms a screw thread along the outward surface to engage with the screw thread of the inward surface of the rotation guide groove (740).

[1042] That is, the curved cover (757) moves away from the rotation pillar (753) as the horizontal movement frame (756) is pressed against the ends of each branch of the “+”-shaped rotor (755) and engages with the threads on the inward surface of the rotation guide groove (740), and moves horizontally in a direction approaching the rotation pillar (753) as the horizontal movement frame (756) is pressed against the corners between the branches of the “+”-shaped rotor (755) so that it can be separated from the threads on the inward surface of the rotation guide groove (740) along the outward surface.

[1043] The cover support spring (758) is installed between the curved cover (757) and the injection body (751) and pulls the curved cover (757) toward the injection body (751).

[1044] The rotary injection unit (750) having the configuration described above may further include a first magnetic body (M1), a second magnetic body (M2), and a magnetic switch (759).

[1045] The first magnetic body (M1) is installed on the inside of the curved cover (757) and forms a magnetism of the “N” pole or the “S” pole by the magnetic switch (759).

[1046] The second magnetic body (M2) is formed in a circular ring shape along the inner side of the rotation guide groove (740) facing the first magnetic body (M1), and forms a magnetism of “N” pole or “S” pole by the magnetic switch (759).

[1047] The magnetic switch (759) switches the magnetism of the first magnetic body (M1) and the second magnetic body (M2) to the “N” pole or the “S” pole to induce the curved cover (757) to be fastened to the inside of the rotation guide groove (740) or to be separated from the inside of the rotation guide groove (740).

[1048] The rotary injection unit (750) having the configuration described above can effectively and precisely achieve adhesion or separation with the inward surface of the rotary guide groove (740).

[1049]

[1050] Fig. 104 is a drawing showing the injection nozzle of Fig. 101.

[1051] Referring to FIG. 104, the injection nozzle (770) includes a nozzle installation groove (771), an elastic cover (772), and a plurality of nozzles (773).

[1052] The nozzle installation groove (771) is formed by recessing into the front end of the rotating injection unit (750).

[1053] The elastic cover (772) is made of an elastic material that can be expanded or contracted and is installed to cover the front opening of the nozzle installation groove (771). As a fluid, such as water or oil, is supplied to the nozzle installation groove (771), the elastic cover expands into a hemispherical shape by hydraulic pressure and returns to a flat shape as the fluid is discharged from the nozzle installation groove (771).

[1054] A plurality of nozzles (773) are installed radially along the elastic cover (772) to spray compressed air. When the elastic cover (772) is flat, the compressed air is sprayed in a direction perpendicular to the elastic cover (772), and the spraying direction of the compressed air changes as the elastic cover (772) expands.

[1055] The spray nozzle (770) having the configuration described above can improve the efficiency of removing foreign substances by varying and precisely changing the spray area of ​​compressed air sprayed through the nozzle (773) as the elastic cover (772) contracts as shown in (a) of FIG. 104 or expands as shown in (b) of FIG. 104.

[1056] Figure 105 is a schematic diagram illustrating the configuration of an anti-pitching inspection system according to one embodiment of the present invention.

[1057] Referring to FIG. 105, an anti-pitching inspection system (10) according to one embodiment of the present invention includes a main frame (100), a rail frame (200), two sensing units (300-1, 300-2), and a good product reading unit (400).

[1058] Anti-pinch is a device that detects the load when the seat is tilted to check whether a passenger is on board and prevent accidents, and is a very important element for passenger safety.

[1059] The present invention is an anti-pinch test device manufactured to determine whether a vehicle seat is operating normally.

[1060] The main frame (100) is installed on one side of an automobile production line (L) for moving a seat tray on which a vehicle seat (S) on which a first sheet (S1) and a second sheet (S2) are installed in close contact is installed.

[1061] In one embodiment, the main frame (100) is configured with a high-strength profile to enhance the structural stability of the equipment. The external cover is made of the same material to protect the electrical components placed inside the system control box from dust or foreign substances generated from the outside, and a reinforcing bar (110) is provided between the main frame (100) and the rail frame (200) to minimize the shaking of the rail frame (200) that is protrudingly installed.

[1062] The rail frame (200) is installed horizontally while looking at the automobile production line (L) from the top of the main frame (100).

[1063] The two sensing units (300-1, 300-2) are installed in a sliding manner on the rail frame (200), and move backward along the rail frame (200) to approach the main frame (100) when the vehicle seat (S) moves, and move forward along the rail frame (200) to face the measurement position of the vehicle seat (S) when measuring the driving pressure of the vehicle seat (S), and sense the driving pressure when the first seat (S1) and the second seat (S2) are folded or unfolded.

[1064] In one embodiment, two sensing units (300-1, 300-2) can move in response to the measurement position of the anti-pinch according to the type of sheet produced in real time.

[1065] The quality reading unit (400) considers whether an error occurs in the sensing information transmitted from the sensing unit (300) and predicts whether the vehicle seat (S) is quality and the probability of occurrence of a failure in the vehicle seat (S).

[1066] In one embodiment, the good product reading unit (400) receives sensing information from the sensing unit (300) and stores it in a database (S110 of FIG. 109), and can predict whether the vehicle seat (S) is good and the probability of occurrence of a failure of the vehicle seat (S) by considering whether an error occurs due to repeated sensing performed by the sensing unit (300).

[1067] In one embodiment, the quality reading unit (400) performs time-series monitoring of sensing information transmitted from the sensing unit (300) (S120 of FIG. 109), and if abnormal pressure data from the sensing unit (300) is confirmed during monitoring, it can notify the manager of this (S170 of FIG. 109).

[1068] In one embodiment, the good product reading unit (400) can extract and store a case in which the probability of failure is high (in the case of Yes in S140 of FIG. 109) in the data distribution of the sensing information received from the sensing unit (300) even if the driving pressure data when folding or unfolding the vehicle seat (S) is within the normal range (in the case of No in S140 of FIG. 109). Here, the case in which the probability of failure is high means a case in which the probability of failure is above a certain value.

[1069] In one embodiment, a case where the probability of failure is high may be when the driving pressure changes abruptly within a numerical range.

[1070] In one embodiment, a case where the probability of failure is high may be when the driving pressure changes outside of a numerical range.

[1071] In one embodiment, the quality reading unit (400) can store the pressure distribution by operating position in the entire section when the vehicle seat (S) is folded or unfolded in a database.

[1072] In one embodiment, the quality reading unit (400) can construct an artificial intelligence-based vehicle seat (S) repair plan derivation model that is trained to derive a repair plan for a vehicle seat (S) in which a defect has occurred by using abnormal pressure data and defect details for each operating position when the vehicle seat (S) is folded or unfolded as input information.

[1073] An anti-pitching inspection system (10) according to one embodiment of the present invention having a configuration as described above can predict whether a vehicle seat is of good quality and the probability of occurrence of a failure of the vehicle seat by considering whether an error occurs in sensing information obtained by sensing the driving pressure.

[1074] Fig. 110 is a drawing showing the rail frame of Fig. 105.

[1075] Referring to FIG. 110, the rail frame (200) includes a horizontal frame (210), two sliding holes (220), two servo motors (230), and two ball screws (240).

[1076] The horizontal frame (210) is installed at the top of the main frame (100) while facing the automobile production line (L) so as to be perpendicular to the direction of movement of the vehicle seat (S), and is configured with two sliding holes (220), two servo motors (230), and two ball screws (240).

[1077] Two sliding holes (220) are formed to extend longitudinally along the horizontal frame (210) so that the upper part of the sensing unit (300) can be settled and moved.

[1078] Two servo motors (230) are installed on the upper side of the front end of the horizontal frame (210) and drive the ball screw (240) to rotate in the forward or reverse direction.
