Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and specifically to a sensor product appearance visual inspection system. Background Technology

[0002] With the development of artificial intelligence, sensors are being used more widely in various fields. However, the production process of sensors is complicated. From the initial production of electronic components, through the combination of light-emitting and light-receiving devices, to appearance, inspection, packaging, and application in intelligent devices and structures, there are detailed process requirements for the shape and electrical characteristics of sensors, especially appearance inspection in automated production.

[0003] The traditional manual inspection mode currently widely used in the industry relies on visual inspection, which suffers from visual fatigue and standard deviation. Visual inspection is significantly affected by the operator's physiological state, and long-term operation can easily lead to missed inspections, misjudgment of direction, and inconsistent defect identification standards, directly affecting the consistency of product batches. At the same time, the detection speed that relies on human eye recognition is difficult to match with modern production lines, which greatly limits production efficiency. This utility model proposes a new solution to the above problems. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks, this utility model provides a sensor-based visual inspection system for the appearance of manufactured products. The objective of this utility model can be achieved by employing the following technical solution:

[0005] This application provides a visual inspection system for the appearance of sensor products, including a rotating visual inspection mechanism, wherein the rotating visual inspection mechanism comprises:

[0006] The rotating turntable mechanism drives the movement trajectory of the products, including the loading station, the inspection station, the defective product unloading station, and the good product unloading station.

[0007] The inspection mechanism includes a recognition camera component for visually identifying products located at the inspection station. When the inspection mechanism detects a defective product, it sends a defective product signal to the processor, and the defective product moves to the defective product unloading station for unloading. When the inspection mechanism detects a good product, it sends a good product signal to the processor, and the good product moves to the good product unloading station for unloading.

[0008] In one possible implementation, the inspection station includes a bottom inspection station and a side inspection station.

[0009] In one possible implementation, the turntable mechanism includes a turntable body and a drive mechanism. The drive mechanism drives the turntable body to rotate around its own axis as the rotation center. The turntable body is provided with the loading station, the bottom surface inspection station, the side surface inspection station, the defective product unloading station and the good product unloading station in sequence along the circumferential direction.

[0010] In one possible implementation, the detection mechanism includes:

[0011] A bottom surface recognition camera is used to identify the bottom surface appearance of a product that has been moved to the bottom surface inspection station.

[0012] A left-side recognition camera is used to perform left-side appearance recognition on products that have moved to the side detection station.

[0013] A right-side recognition camera is used to perform right-side appearance recognition on products that have moved to the side inspection station.

[0014] In one possible implementation, the turntable mechanism further includes a material unloading station, which is located behind the good product unloading station.

[0015] The sensor-based product appearance visual inspection system also includes a judgment sensor, which is positioned opposite to the judgment unloading station. When the judgment sensor detects that there is no product at the judgment unloading station, it sends a successful unloading signal to the processor. When the judgment sensor detects that there is a product at the judgment unloading station, it sends a unloading failure signal to the processor.

[0016] In one possible implementation, the turntable mechanism further includes at least one empty station, with adjacent stations having the same included angle.

[0017] In one possible implementation, the outer periphery of the turntable body is provided with a plurality of protrusions along the circumferential direction, and the included angle between adjacent protrusions is the same. The loading station, the bottom surface inspection station, the side surface inspection station, the defective product unloading station, the good product unloading station, the judgment unloading station, and the plurality of empty stations are all independently arranged on the opposite protrusions.

[0018] In one possible implementation, the sensor-based product appearance visual inspection system further includes a pickup cylinder, a material transfer cylinder, a material unloading cylinder, and a material discharge cylinder.

[0019] The pick-up cylinder moves the product to the loading station. The turntable mechanism rotates the product to the bottom surface inspection station and performs bottom surface appearance recognition via the bottom surface recognition camera. The turntable mechanism rotates the product to above the side inspection station. The transfer cylinder moves the product to the side inspection station and performs left and right side appearance recognition via the left and right side recognition cameras. The turntable mechanism rotates the product to the defective product unloading station, where the unloading cylinder unloads the defective product. The turntable mechanism rotates the product to the good product unloading station, where the unloading cylinder unloads the good product.

[0020] In one possible implementation, the sensor-based product appearance visual inspection system further includes a top surface inspection station and a top surface recognition camera. The top surface recognition camera performs top surface appearance recognition on products that move to the top surface inspection station. The top surface inspection station is located on the protrusion of the turntable body.

[0021] In one possible implementation, the sensor-based product appearance visual inspection system includes a material unloading and packaging mechanism, which has a top surface inspection station. The inspection mechanism also includes a top surface recognition camera, which performs top surface appearance recognition on products that move to the top surface inspection station.

[0022] The beneficial technical effects of this utility model are as follows: According to the present disclosure, the sensor product appearance visual inspection system includes a turntable mechanism and an inspection mechanism. It adopts a multi-level visual inspection mechanism. The product passes through the inspection mechanism in sequence for appearance identification. After the turntable mechanism screens the bottom and side defects of the product, a top surface inspection station is added to screen the top surface defects of the product. Multi-angle image acquisition realizes multi-angle detection of product appearance defects, effectively eliminating blind spots in manual visual inspection, ensuring accurate identification of various types of defects such as minor scratches and structural deformation, and significantly improving the efficiency, reliability and safety of the sensor product inspection process.

[0054] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of this utility model more clearly, the embodiments described below are not limited thereto. The present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0055] like Figure 3 , Figure 9 and Figure 10 As shown, this application provides a sensor-based visual inspection system for product appearance, including a rotary visual inspection mechanism 22. The rotary visual inspection mechanism 22 includes a turntable mechanism 221 and an inspection mechanism 222. The rotating turntable mechanism 221 drives the movement trajectory of the product 100, which includes a loading station 2211, an inspection station, a defective product unloading station 2214, and a good product unloading station 2215. The inspection mechanism 222 includes a recognition camera assembly for performing appearance recognition on the product 100 located at the inspection station. When the inspection mechanism 222 detects that the product 100 has a defective appearance, it sends a defective product signal to the processor, and the defective product 100 moves to the defective product unloading station 2214 for unloading. When the inspection mechanism 222 detects that the product 100 has a good appearance, it sends a good product signal to the processor, and the good product 100 moves to the good product unloading station 2215 for unloading.

[0056] The sensor-based visual inspection system for product appearance provided in this embodiment includes a turntable mechanism 221 and an inspection mechanism 222. The turntable mechanism 221 rotates uniformly around its axis, and its surface has multiple stations distributed circumferentially, namely, a loading station 2211, an inspection station, a defective product unloading station 2214, and a good product unloading station 2215. Product 100 enters the turntable mechanism 221 from the loading station 2211 and passes through each station sequentially as the turntable mechanism 221 rotates. A recognition camera takes a picture of product 100 at the inspection station, and a processor analyzes the image, reducing human error, significantly lowering labor costs, improving inspection consistency, and greatly improving the efficiency and coverage of sensor-based product appearance inspection. It also controls the actions of the corresponding unloading stations. The continuous rotation of the turntable mechanism 221 achieves efficient automated inspection, and the multi-station collaboration ensures seamless connection between inspection and sorting, greatly improving inspection and sorting efficiency.

[0057] The sensor product appearance visual inspection system provided in this embodiment adopts a multi-level visual inspection mechanism. The product 100 is sequentially identified by the inspection mechanism 222. After the bottom and side defects of the product 100 are screened by the turntable mechanism 221, a top surface inspection station is added to screen the top surface defects of the product 100. Multi-angle image acquisition is used to realize multi-angle detection of appearance defects of the product 100, effectively eliminating blind spots of manual visual inspection, ensuring accurate identification of various types of defects such as minor scratches and structural deformation, and significantly improving the efficiency, reliability and safety of the sensor product 100 inspection process.

[0058] In one possible implementation, such as Figure 9 and Figure 10 As shown, the inspection station includes a bottom inspection station 2212 and a side inspection station 2213.

[0059] The inspection station can be further divided into a bottom inspection station 2212 and a side inspection station 2213. The bottom inspection station 2212 is located below the turntable mechanism 221 and takes pictures of the bottom surface of the product 100, namely the functional surface and the PIN foot 101, from an upward angle. The side inspection station 2213 is located below the turntable and takes pictures of the side surface of the product 100 from a horizontal angle. The multi-area inspection covers more appearance surfaces, avoids blind spots and missed inspections, and the multi-stage inspection can optimize the light source arrangement, improve image contrast, and improve the inspection accuracy of the sensor product 100.

[0060] In one possible implementation, such as Figure 9 and Figure 10 As shown, the turntable mechanism 221 includes a turntable body and a drive mechanism. The drive mechanism drives the turntable body to rotate around its own axis as the rotation center. The turntable body is provided with a feeding station 2211, a bottom inspection station 2212, a side inspection station 2213, a defective product unloading station 2214, and a good product unloading station 2215 in sequence along the circumferential direction.

[0061] The turntable body is driven to rotate by a drive mechanism, which includes a servo motor or a stepper motor. The workstations are arranged at equal angles along the circumference, i.e., loading → bottom inspection → side inspection → unloading of defective products → unloading of good products. The distance between the workstations matches the rotation step angle of the turntable to ensure accurate positioning for each rotation. The distribution of workstations at equal angles simplifies the motion control logic and improves the repeatability of positioning.

[0062] In one possible implementation, such as Figure 9 and Figure 10As shown, the inspection mechanism 222 includes a bottom surface recognition camera 2221, a left side surface recognition camera 2222, and a right side surface recognition camera 2223. The bottom surface recognition camera 2221 performs bottom surface appearance recognition on the product 100 that has moved to the bottom surface inspection station 2212, the left side surface recognition camera 2222 performs left side surface appearance recognition on the product 100 that has moved to the side surface inspection station 2213, and the right side surface recognition camera 2223 performs right side surface appearance recognition on the product 100 that has moved to the side surface inspection station 2213.

[0063] Among them, the bottom surface recognition camera 2221 is vertically mounted to photograph the bottom surface of the product 100, while the left and right side recognition cameras 2223 are horizontally aligned to photograph the left and right sides of the product 100 from both sides at an angle. Multi-angle image acquisition comprehensively captures appearance defects, such as scratches and missing materials, eliminates blind spots in single-sided shooting, and improves detection consistency.

[0064] Among them, the bottom surface recognition camera 2221 shoots vertically upwards and, together with the detection light source, captures the integrity of the bottom surface structure of the product 100. The left side recognition camera 2222 and the right side recognition camera 2223 are set opposite to the side detection station 2213, and the diffuse reflection light source is used to eliminate reflection interference and extract the side contour and surface details.

[0065] The recognition camera consists of a high-resolution industrial camera, a light source module, and an image processing unit. It is fixed below, above, or to the side of the detection station and triggers shooting synchronously with the movement of the turntable mechanism 221.

[0066] Understandably, the camera trigger signal is synchronized with the position of the turntable mechanism 221 to ensure accurate shooting timing.

[0067] In one possible implementation, such as Figure 9 and Figure 10 As shown, the turntable mechanism 221 also includes a judgment unloading station 2216, which is located behind the good product unloading station 2215. The sensor product appearance visual inspection system also includes a judgment sensor, which is set opposite to the judgment unloading station 2216. When the judgment sensor detects that there is no product 100 on the judgment unloading station 2216, it sends a unloading success signal to the processor. When the judgment sensor detects that there is product 100 on the judgment unloading station 2216, it sends a unloading failure signal to the processor.

[0068] Among them, a judgment unloading station 2216 can be added after the good product unloading station 2215, and a judgment sensor can be installed to monitor the unloading status in real time, prevent missed or falsely detected products from flowing into the next stage, and reduce downtime for troubleshooting by abnormal alarms, thereby improving the reliability of the detection system.

[0069] If product 100 is successfully unloaded at defective product unloading station 2214 or good product unloading station 2215, it is determined that there is no product 100 at unloading station 2216. If unloading fails, it is determined that the sensor has detected residual product 100 and an alarm is triggered.

[0070] In one possible implementation, such as Figure 9 and Figure 10 As shown, the turntable mechanism 221 also includes at least one empty station, with the same angle between adjacent stations.

[0071] Among them, empty stations can be reserved between adjacent functional stations. Empty stations are buffer stations without detection or operation equipment. The number of empty stations is set according to the cycle time requirements. Empty stations provide mechanical buffering, reduce the risk of interference between stations, extend the dwell time of products, facilitate stable posture, and improve the stability and reliability of detection.

[0072] In one possible implementation, such as Figure 9 and Figure 10 As shown, the outer periphery of the turntable body is provided with several protrusions along the circumferential direction, and the included angle between adjacent protrusions is the same. The loading station 2211, the bottom inspection station 2212, the side inspection station 2213, the defective product unloading station 2214, the good product unloading station 2215, the judgment unloading station 2216, and several empty stations are all independently set on the corresponding protrusions.

[0073] The turntable body can be machined with several equidistant protrusions on its outer edge. Each protrusion carries a workstation. Positioning holes 302 or slots can be machined on the protrusions to fix the conveying mechanism 2217. The empty workstations on the protrusions can also reserve standard interfaces. If new functional modules are added later, such as top surface inspection or cleaning workstations, the empty workstation modules can be directly replaced without modifying the main structure of the turntable. This facilitates modular maintenance or replacement of workstations and provides strong expandability.

[0074] In one possible implementation, the sensor-based product appearance visual inspection system further includes a pickup cylinder 2131, a transfer cylinder 223, a discharge cylinder 224, and a unloading cylinder, such as... Figure 4 , Figure 5 , Figure 8 As shown, the pick-up cylinder 2131 moves the product 100 to the loading station 2211, as... Figure 9 and Figure 10As shown, the turntable mechanism 221 rotates the product 100 to the bottom surface inspection station 2212, where the bottom surface appearance is recognized by the bottom surface recognition camera 2221. The turntable mechanism 221 then rotates the product 100 to above the side inspection station 2213. The transfer cylinder 223 moves the product 100 to the side inspection station 2213, where the left side and right side appearances are recognized by the left side recognition camera 2222 and the right side recognition camera 2223. Finally, the turntable mechanism 221 rotates the product 100 to the defective product unloading station 2214, where the unloading cylinder 224 unloads the defective product 100. Figure 13 and Figure 14 As shown, the turntable mechanism 221 drives the product 100 to rotate to the good product unloading station 2215, and the unloading cylinder unloads the good product 100.

[0075] The process involves several steps: Pick-up cylinder 2131 moves the product 100 from the loading station to the loading station 2211; transfer cylinder 223 pushes the product 100 downwards to the side inspection station 2213; unloading cylinder 224 removes the defective product 100 from the defective product unloading station 2214 to the waste bin or rework line based on the inspection results; and discharge cylinder removes the good product 100 from the good product unloading station 2215 to the unloading and packaging mechanism 23 based on the inspection results. The cylinder-driven operation achieves high-precision point-to-point control, has a fast response speed, reduces the turntable load through station-based operation, and improves the efficiency of parallel inspection and transfer.

[0076] In one possible implementation, such as Figure 11 and Figure 13 As shown, the sensor-based product appearance visual inspection system also includes a top surface inspection station and a top surface recognition camera 2313. The top surface recognition camera 2313 performs top surface appearance recognition on the product 100 that moves to the top surface inspection station. The top surface inspection station is set on the protrusion of the turntable body.

[0077] Among them, a top surface inspection station is added to the turntable body. The top surface recognition camera 2313 is vertically downward to photograph the top appearance of the product 100, which completes the top surface defect detection capability. Combined with the feeding and packaging mechanism 23, a closed loop of the entire process of inspection-sorting-packaging is realized.

[0078] In one possible implementation, the sensor-based product appearance visual inspection system includes a feeding and packaging mechanism 23, which has a top surface inspection station. The inspection mechanism 222 also includes a top surface recognition camera 2313, which performs top surface appearance recognition on the product 100 that moves to the top surface inspection station.

[0079] Among them, a top surface inspection station is added to the feeding and packaging mechanism 23. The top surface recognition camera 2313 is vertically downward to photograph the top appearance of the product 100, which completes the top surface defect detection capability. Combined with the turntable mechanism 221, the entire process of detection-sorting-inspection-packaging is closed-loop.

[0080] like Figures 1-22 As shown, this application provides an automatic inspection and packaging system for sensor products, applied to sensor products 100. Several products 100 are grouped together and placed within a carrier 200. The automatic inspection and packaging system includes a transmission inspection mechanism 2, which includes a feeding mechanism 21, a rotary vision inspection mechanism 22, and a unloading and packaging mechanism 23. The feeding mechanism 21 includes an unloading mechanism 211, a feeding mechanism 212, and a picking mechanism 213. The unloading mechanism 211 is used to unload the grouped products 100 from the carrier 200, and the products 100 are conveyed to the picking mechanism 213 via the feeding mechanism 212. The rotary vision inspection mechanism 22 includes a turntable mechanism 221 and an inspection mechanism 222. The turntable mechanism 221 includes an upper... The feeding station 2211 and the inspection station are equipped with a picking mechanism 213 that transports a single product 100 to the feeding station 2211. The rotating turntable mechanism 221 moves the product 100 to the inspection station. The inspection mechanism 222 is used to perform appearance recognition on the product 100. The unloading and packaging mechanism 23 includes an unloading and taping inspection mechanism 231 and a taping and packaging mechanism 232. After the inspection mechanism 222 detects the qualified product 100, it is unloaded into the taping 300 placement slot 301 of the unloading and taping inspection mechanism 231. The movement of the taping 300 moves the qualified product 100 to perform appearance recognition through the top recognition camera 2313. The taping and packaging mechanism 232 packages and winds the recognized product 100 to form a finished product.

[0081] The automatic inspection and packaging system for sensor products provided in this embodiment adopts an automated conveying mechanism. The customized carrier 200 transports the grouped products 100 in an orderly manner, eliminating the redundancy of manual handling and significantly reducing the risk of surface wear, electrostatic interference, or accidental drops caused by repeated contact. It provides reliable protection for the sensors and ensures the directional consistency of the products 100. The high-precision positioning design of the carrier 200 and the conveyor line ensures that the products 100 always maintain the preset orientation during the flow process, eliminating subsequent automated production problems caused by directional deviations, and improving the efficiency, reliability, and safety of the sensor product 100 conveying process.

[0082] The automatic inspection and packaging system for sensor products provided in this embodiment adopts a standardized packaging process. The feeding and packaging mechanism 23 enables continuous and accurate feeding of qualified products 100 onto the tape, avoiding the uneven spacing or misalignment problems that may occur with traditional manual tape weaving. This improves the storage safety of the sensor products 100 rolls, significantly increases operational efficiency, strengthens the process stability of products 100 under high-speed circulation, provides a reliable material supply guarantee for subsequent automated production lines, and significantly improves the efficiency, reliability, and safety of the sensor product 100 packaging process.

[0083] The automatic inspection and packaging system for sensor products provided in this embodiment forms a complete inspection and packaging production line through the feeding mechanism 21, the rotating vision inspection mechanism 22, and the unloading and packaging mechanism 23, achieving a smooth connection from inspection to packaging, reducing manual intervention, and improving production line efficiency.

[0084] In one possible implementation, such as Figure 16 and Figure 17 As shown, the top of the product 100 is provided with a pin 101, and the bottom of the product 100 is provided with a front / back identification chamfer 102, as shown. Figures 19-22 As shown, the carrier 200 is provided with a plurality of partitions 201, and a receiving compartment 202 for accommodating a single product 100 is formed between adjacent partitions 201. The product 100 is inverted in the receiving compartment 202 with the pin 101 facing upward.

[0085] Among them, such as Figure 16 and Figure 17 As shown, the PIN 101 on the top of the product 100 serves as the core electrical contact component. The inverted layout with the PIN 101 facing upwards exposes the key functional surface. During the subsequent unloading process of the unloading mechanism 211, it facilitates the lifting mechanism 2113 to perform the ejection action on the product 100, avoiding mechanical stress impact on the PIN 101. The front and back recognition chamfer 102, i.e., the asymmetrical chamfer on the bottom surface of the product 100, can reduce the feature recognition complexity of the subsequent detection mechanism 222.

[0086] Among them, such as Figures 19-22 As shown, the independent accommodating compartment 202 formed by adjacent partitions 201 can achieve horizontal constraint of the product 100 through the elastic limiting structure 203. The sidewall of the partition 201 can be made of a low-friction coefficient composite material (such as POM engineering plastic), which reduces the risk of scratches and avoids the adsorption of precision electronic components through the electrostatic dissipation coating. The compartment depth matches the height of the product 100 to form a longitudinal limit, preventing vertical displacement caused by transportation vibration. The bottom opening 204 of the carrier 200 allows the lifting mechanism 2113 to directly contact the non-functional surface of the product 100 to perform the ejection action, avoiding the mechanical stress impact on the PIN foot 101 caused by traditional manual handling or clamping unloading.

[0087] Among them, the high-precision positioning design of the carrier 200 and the conveyor line ensures that the product 100 always maintains the preset orientation during the flow process. Through the dual protection of mechanical limit and visual auxiliary calibration, the angle deviation or inversion that may be caused by manual placement is completely avoided, fundamentally cutting off the risk path of directional deviation to subsequent automated welding and assembly processes, and maintaining the stability of continuous operation of the production line.

[0088] In one possible implementation, such as Figures 19-22 As shown, the main body 205 of the vehicle is long and narrow, and the accommodating compartments 202 are arranged in a row on the sunken platform. The accommodating compartments 202 include a top opening, a front opening and a rear opening.

[0089] The main body 205 of the carrier is designed as a long strip, and the accommodating compartments 202 are arranged in rows along the length of the sunken platform. The long strip structure is suitable for conveyor belt or assembly line layout, improving space utilization. The accommodating compartments 202 include a top opening for vertical loading and unloading, and through openings on the front and rear sides, namely the front opening and the rear opening, for taking the product 100 into the Rong'an compartment through the top opening at both ends.

[0090] In one possible implementation, such as Figure 4 and Figure 20 As shown, the receiving compartment 202 also includes a bottom opening 204, the cross-sectional area of ​​which is smaller than that of the receiving compartment 202, so as to form a support platform for supporting the article 100.

[0091] A square or circular opening 204 is provided at the bottom of the receiving compartment 202. This bottom opening 204 allows the lifting mechanism 2113 to contact the product 100 from below. The bottom opening 204 is adapted to the shape of the support column, facilitating the lifting and transfer of the product 100. The size of the bottom opening 204 is smaller than the projected area of ​​the bottom surface of the product 100, forming a ring-shaped or partial support platform. After the product 100 is placed in the receiving compartment 202, the bottom edge or a partial area of ​​the product 100 contacts the support platform, with the main body suspended above the bottom opening 204. The support platform provides stable support, preventing the product 100 from falling off the bottom.

[0092] In one possible implementation, such as Figure 22 As shown, the width of the recessed platform is not greater than the width of the product 100, so that a portion of the product 100 in the accommodating compartment 202 is flush with or protrudes from the partition 201 in the vertical direction.

[0093] The width of the recessed platform is equal to the width of the product 100, so that the product 100 in the receiving compartment 202 is vertically flush with the partition 201, that is, the sidewall of the product 100 is flush with the partition 201; or the width of the recessed platform is slightly smaller than the width of the product 100, so that the product 100 in the receiving compartment 202 protrudes vertically from the partition 201, that is, the sidewall of the product 100 slightly protrudes from the partition 201 and is exposed outside the partition 201. The sidewall of the product 100 can serve as a force point for manual handling, reducing friction from contact with the inner wall of the receiving compartment 202, which is especially suitable for products 100 with fragile surfaces or flanges.

[0094] In one possible implementation, such as Figure 19 As shown, the compartment 202 is provided with an elastic limiting structure 203, and the partition 201 is connected to the product 100 through the elastic limiting structure 203.

[0095] An elastic limiting structure 203, made of elastic material such as a silicone pad, spring sheet, or rubber block, is provided inside the partition 201. This structure generates a flexible clamping force on the product 100 through pre-compression deformation. The elastic structure can also be arc-shaped to better conform to the contour of the product 100, facilitating its entry and exit from the receiving compartment 202. The elastic limiting structure adapts to the dimensional tolerances of the product 100, preventing deformation caused by rigid compression, buffering vibrations and impacts, and preventing the product 100 from shifting during movement.

[0096] In one possible implementation, such as Figure 19 As shown, the vehicle body 205 has gripping parts 206 at both ends, and the width of the gripping parts 206 is greater than the width of the vehicle body 205.

[0097] The carrier body 205 extends outward at both ends to form a widened gripping part 206. The surface of the gripping part 206 is processed with anti-slip texture or wrapped with anti-slip material. Its thickness is greater than that of the carrier body 205 to provide gripping space. The gripping part 206 improves the gripping stability during manual handling, reduces the risk of slippage, and enhances operational safety. At the same time, it can also serve as a positioning reference for the carrier 200 on the conveyor line.

[0098] In one possible implementation, such as Figures 3-8As shown, the unloading mechanism 211 includes a lifting mechanism 2113, a movable pallet 2111, a pressure plate 2112, and a separation cylinder 2114. The lifting mechanism 2113 includes a plurality of spaced-apart pillars, which are correspondingly arranged with the receiving compartment 202. The receiving compartment 202 has a bottom opening 204 for the pillars to pass through. When the carrier 200 passes through the lifting mechanism 2113 from top to bottom, the product 100 is placed on the top of the pillars. The movable pallet 2111 includes a first pallet and a second pallet arranged opposite each other, with a receiving cavity formed between the first pallet and the second pallet. The lifting mechanism 2113... The lifting mechanism 2113 is movably connected to the movable pallet 2111 and moves towards the movable pallet 2111, thus moving the product 100 into the receiving cavity. The pressure plate 2112 is located above the receiving cavity and can move up and down to press or release the product 100 in the receiving cavity. The output end of the separating cylinder 2114 is connected to the lifting mechanism 2113 and is used to drive the lifting mechanism 2113 to move up and down. After the lifting mechanism 2113 moves the product 100 into the receiving cavity, the separating cylinder 2114 drives the lifting mechanism 2113 to move downward and separate from the product 100.

[0099] Among them, such as Figures 4-6 As shown, the spacing and diameter of the supports of the lifting mechanism 2113 are adapted to the bottom opening 204 of the compartment 202 of the carrier 200. When the carrier 200 descends vertically, the supports penetrate the bottom opening 204 of the carrier 200 and precisely lift the non-functional surface of the bottom of the product 100, ensuring that the lifting process will not damage the PIN 101. Furthermore, the top of the supports is embedded in the groove of the non-functional surface of the bottom of the product 100 to improve stability. The gap width between adjacent supports is slightly larger than the thickness of the partition 201 of the carrier 200, forming a mechanical clearance space and eliminating the risk of interference in the mechanism's movement.

[0100] The top of the support column can be fitted with an anti-slip pad to resist the inertial force generated when the lifting mechanism 2113 moves horizontally, preventing the product 100 from slipping during the movement of the lifting mechanism 2113. The anti-slip pad can be made of polymer composite materials such as polyurethane or silicone rubber, which can effectively resist the inertial force generated when the lifting mechanism 2113 moves horizontally; it can also have interlaced diamond-shaped raised patterns on the surface of the anti-slip pad to form multi-directional anti-slip grooves, disrupting the continuous contact surface of the bottom of the product 100 and increasing the sliding resistance threshold. Carbon fiber conductive material can also be incorporated into the anti-slip pad to conduct accumulated static charge into the equipment grounding system through a grounding wire, reducing the impact of static electricity on the product 100.

[0101] A receiving cavity is formed between the first and second pallets, with the width of the cavity slightly larger than the width of the product 100. When the lifting mechanism 2113 slides horizontally into the receiving cavity along the linear guide rail, a portion of the lifting mechanism 2113 is located between the first and second pallets. The separating cylinder 2114 drives the lifting mechanism 2113 to carry the product 100 down synchronously into the pallet receiving cavity. The pressure plate 2112 presses down to form a stable clamp on the product 100 in the receiving cavity. The bottom shape of the pressure plate 2112 matches the top shape of the product 100, avoiding damage to the key functional surfaces of the product 100. The separating cylinder 2114 drives the lifting mechanism 2113 down. After the support column is completely detached from the bottom of the product 100, the lifting mechanism 2113 initiates a horizontal removal action. After the lifting mechanism 2113 resets, the carrier 200 unlocks, completing a single unloading cycle and achieving a non-destructive and efficient transfer of the product 100 from the carrier 200 to the moving pallet 2111.

[0102] Understandably, the width of the cavity can be dynamically adjusted to meet the needs of products of different sizes.

[0103] In one possible implementation, such as Figures 1-8 As shown, the feeding mechanism 212 includes a tilting wheel 2121, a linear conveying track 2122, a linear feeder 2123, a shut-off mechanism 2124, and a distributing mechanism 2125. The tilting wheel 2121 includes an arc-shaped slide. The product 100 in the receiving cavity is tilted 180° up and down through the arc-shaped slide. The tilting wheel 2121 conveys the tilted and upright product 100 to the linear conveying track 2122. The linear feeder 2123 is connected to the linear conveying track 2122 and drives the product 100 to move linearly on the linear conveying track 2122. The stopping mechanism 2124 is located at one end of the linear conveyor track 2122 away from the turning wheel 2121. It is used to form an adsorption stop on the product 100 that has moved to the end of the linear conveyor track 2122, so that it is located at the stopping position. The material distribution mechanism 2125 drives the product 100 located at the stopping position to move away from the linear conveyor track 2122 until it moves to the loading position. The picking mechanism 213 includes a picking cylinder 2131, which is used to drive the product 100 located at the loading position to move to the loading station 2211.

[0104] Among them, such as Figure 7 As shown, the arc-shaped slide of the flipping wheel 2121 matches the outer contour of the product 100, ensuring that the product 100 is always laterally constrained during the flipping process. The inner wall of the slide can be embedded with a low-friction coefficient polymer material (such as PTFE) to reduce sliding resistance. At the same time, the guide roller assembly guides the product 100 to complete a 180° up-and-down flip along a preset trajectory, avoiding jamming or collision.

[0105] Among them, such as Figure 4 and Figure 5As shown, the linear feeder 2123 generates directional excitation force through an electromagnetic vibrator or a vibrating motor. The electromagnetic vibrator consists of an electromagnetic coil, an armature, and a spring plate. When the alternating current passes through the coil, it generates a periodic magnetic field, which drives the product 100 to form a linear reciprocating motion with the linear conveying track 2122. The vibrating motor generates centrifugal force through the rotation of the eccentric block. Its horizontal component force is converted into directional vibration of the linear conveying track 2122, which pushes the product 100 forward along the linear conveying track 2122. Through the synergistic effect of vibration drive and magnetic field control, the linear feeder 2123 and the linear conveying track 2122 achieve efficient directional conveying and precise release of the product 100, which is especially suitable for automated assembly scenarios such as electronic components and precision parts.

[0106] Among them, such as Figure 8 As shown, the cut-off mechanism 2124 includes a cut-off cylinder 21241 and a conveying mechanism 2217. When the product 100 reaches the end of the linear conveying track 2122, the cut-off cylinder 21241 drives the conveying mechanism 2217 to rise to a preset height. The magnetic suction component 22173 in the conveying mechanism 2217 attracts the surface of the product 100 through a magnetic field. The magnetic attraction force counteracts the residual inertia of the linear conveying track 2122, forcing the product 100 to stop precisely at the cut-off position at the end of the track.

[0107] Understandably, the magnetic component 22173 supports dynamic adjustment of the magnetic field strength. It can be adapted to products 100 of different weights or materials by replacing permanent magnets with different magnetic forces or by using electromagnets, thus meeting the needs of products 100 of different specifications.

[0108] Among them, such as Figure 8 As shown, the material distribution mechanism 2125 includes a material distribution cylinder 21251 and a conveying mechanism 2217. When the product 100 reaches the cutoff position at the end of the linear conveying track 2122, the material distribution cylinder 21251 drives the conveying mechanism 2217 to move horizontally closer to the product 100. The magnetic suction component 22173 in the conveying mechanism 2217 adsorbs the surface of the product 100 through the magnetic field. After the adsorption is completed, the material distribution cylinder 21251 retracts in the opposite direction, driving the conveying mechanism 2217 and the adsorbed single product 100 to move away from other products 100 to be processed in the horizontal direction, avoiding stacking interference and ensuring that the product 100 is accurately stopped at the loading position.

[0109] Understandably, it is also possible to set a cutoff position sensor and a material distribution position sensor to detect the position signal of product 100, triggering cylinder extension / retraction commands and / or electromagnetic power-on / off commands.

[0110] Among them, such as Figure 8As shown, the picking mechanism 213 includes a picking cylinder 2131 and a conveying mechanism 2217. When the product 100 arrives at the loading position, the picking cylinder 2131 drives the conveying mechanism 2217 to move downwards and approach the product 100. The magnetic suction component 22173 in the conveying mechanism 2217 attracts the non-functional surface of the product 100 through the magnetic field. After the attraction is completed, the picking cylinder 2131 retracts in the opposite direction, driving the conveying mechanism 2217 and the attracted single product 100 to move upwards to the loading position 2211 of the turntable mechanism 221.

[0111] like Figure 4 and Figure 5 As shown, the automatic sensor product detection and packaging system provided in this embodiment uses a feeding mechanism 212 to allow the product 100 to be flipped up and down via a flipping wheel 2121. This corrects the orientation of the product 100, ensuring that its functional surfaces face in a uniform manner. After flipping, the product 100 is released to the starting end of the linear conveyor track 2122. The product 100 moves continuously on the linear conveyor track 2122 driven by the linear feeder 2123, smoothly reaching the end of the conveyor track. When the product 100 reaches the end of the linear conveyor track 2122, the stop cylinder 21241 drives the handling mechanism 2 217 rises and magnetically fixes product 100, stopping its movement and precisely positioning it at the cutoff position; the dispensing cylinder 21251 then starts, driving the conveying mechanism 2217 to move horizontally to adsorb product 100, separating individual product 100 from the dense queue and moving it to an independently set loading position; the picking cylinder 2131 drives the conveying mechanism 2217 to move vertically down to the loading position, and after the conveying group adsorbs product 100, it is vertically lifted to the loading position 2211 height of the turntable mechanism 221, and the conveying mechanism 2217 carries product 100 and rotates synchronously with the turntable to the inspection position.

[0112] In one possible implementation, such as Figure 8 , Figure 10 , Figure 13 , Figure 14 and Figure 15 As shown, the automatic detection and packaging system for sensor products also includes a conveying mechanism 2217. The conveying mechanism 2217 is used to connect the product 100. The conveying mechanism 2217 includes a connector 22172 and a magnetic attractor 22173. The connector 22172 is movably connected to the slide rail 22171. The magnetic attractor 22173 is disposed on the connector 22172. When the connector 22172 is close to the product 100, it attracts the product 100 through the magnetic attractor 22173 to achieve mutual connection.

[0113] The conveying mechanism 2217 includes a connector 22172 and a magnetic suction component 22173. The magnetic suction component 22173 is disposed on the connector 22172, and the connector 22172 is connected to the product 100 through the magnetic suction component 22173. The magnetic suction component 22173 is fixed to the end of the connector 22172, and the sensor product 100 with magnetic characteristics is attracted by magnetic force. The magnetic connection enables quick assembly and disassembly, avoiding indentations or wear on the sensor surface caused by mechanical grippers and manual handling. The connector 22172 provides stable support to ensure that the posture of the product 100 is fixed during the conveying process. It is suitable for the automated conveying of lightweight, high-precision sensors.

[0114] It is understandable that the connector 22172 is connected to an external drive device, which drives the conveying mechanism 2217 to move the product 100.

[0115] In one possible implementation, the magnetic attractor 22173 includes a permanent magnet or an electromagnet, the article 100 includes a magnetic material, and when the connector 22172 approaches the article 100, it attracts the article 100 to achieve mutual connection.

[0116] Among them, the magnetic suction component 22173 is a permanent magnet or an adjustable electromagnet. During transportation, the connector 22172 drives the magnetic suction component 22173 to approach the product 100 to the effective working distance. The magnetic force triggers the adsorption action, realizing the rapid connection between the connector 22172 and the product 100.

[0117] Understandably, the magnetic component 22173 supports dynamic adjustment of the magnetic field strength. It can be adapted to products 100 of different weights or materials by replacing permanent magnets with different magnetic forces or by using electromagnets, thus meeting the needs of products 100 of different specifications.

[0118] Among them, the permanent magnet has a simple structure and requires no power supply, making it suitable for low-power scenarios; the electromagnet solution can adjust the attraction force through current, adapting to products 100 of different weights or materials, offering greater flexibility. Both reduce the risk of mechanical stress damage to product 100.

[0119] In one possible implementation, such as Figure 8 As shown, the conveying mechanism 2217 also includes a slide rail 22171, and a connector 22172 is movably connected to the slide rail 22171.

[0120] The connector 22172 is movably connected to the slide rail 22171 via a slider 22174 and is driven by a cylinder or motor to move along the slide rail 22171. The slide rail 22171 is mounted on the equipment frame and defines the direction of movement of the connector 22172, which is basically horizontal or vertical. The slide rail 22171 provides precise guidance, eliminates offset during handling, and ensures controllable movement trajectory, thereby improving positioning accuracy and repeatability.

[0121] In one possible implementation, such as Figures 13-15 As shown, the connector 22172 includes a slider 22174 and a connecting plate 22175. The slider 22174 can slide along the slide rail 22171. The connecting plate 22175 is disposed on the slider 22174 for connecting with the product 100. The magnetic suction member 22173 is disposed on the connecting plate 22175.

[0122] The connector 22172 consists of a slider 22174 and a connecting plate 22175. The slider 22174 is a moving part that cooperates with the slide rail 22171, and the connecting plate 22175 is a loading platform that contacts the product 100. The slider 22174 slides along the slide rail 22171, and the connecting plate 22175 is fixed on the slider 22174 and supports the magnetic component 22173. The slider 22174 shares the motion load, and the connecting plate 22175 focuses on the adsorption function. The modular design of the handling mechanism 2217 facilitates disassembly and maintenance, reduces the overall weight, improves the dynamic response speed, and is suitable for high-frequency handling operations.

[0123] In one possible implementation, such as Figure 15 As shown, when the slide rail 22171 is in a vertical state, the moving trajectory of the connecting member 22172 includes a first position and a second position from top to bottom. The slide rail 22171 is provided with an elastic member 22176. The first end of the elastic member 22176 is fixed relative to the position of the slide rail 22171, and the second end of the elastic member 22176 is connected to the connecting member 22172 to apply an elastic force to the connecting member 22172 to move towards the first position.

[0124] The slide rail 22171 is vertically installed, and the connecting piece 22172 can move from a high first position to a low second position on the slide rail 22171. The slide rail 22171 may have a built-in compression spring, tension spring, or elastic element 22176, one end of which is fixed to the end of the slide rail 22171, and the other end is connected to the slider 22174. When the external force drives the connecting piece 22172 to press down, the elastic element 22176 stores energy. After the external force disappears, the elastic force drives the connecting piece 22172 to automatically return to the high position.

[0125] When the conveying mechanism 2217 moves quickly or stops suddenly, the elastic element 22176 absorbs kinetic energy through elastic deformation, reduces the impact of instantaneous impact force on the product 100, prevents slippage or displacement due to inertia, and the elastic restoring force of the spring can offset the vibration caused by acceleration changes during the conveying process, maintaining stable contact between the product 100 and the connecting element 22172.

[0126] Among them, the elastic reset reduces the need for active drive and lowers energy consumption; the vertical movement adapts to the direction of gravity, avoiding positioning deviations caused by its own weight, and is suitable for handling operations that require frequent lifting and lowering.

[0127] In one possible implementation, a damping layer is provided on the slide rail 22171, and the slide rail 22171 uses the damping layer to fix the position of the connector 22172 in a state where no external force is applied.

[0128] Among them, a damping layer can be added to the surface of the slide rail 22171 to increase the static friction force so that the connecting part 22172 remains stationary when there is no external driving force, preventing accidental displacement caused by inertia or vibration, improving the stability during the handling process, especially preventing the product 100 from slipping off in emergency stop or vibration environment, eliminating the need for locking mechanisms such as elastic part 22176, and simplifying the mechanism.

[0129] In one possible implementation, such as Figure 14 and Figure 15 As shown, the end of the slide rail 22171 is provided with a baffle to stop the movement of the slider 22174 so that the slider 22174 and the slide rail 22171 remain connected.

[0130] The slide rail 22171 has fixed baffles at both ends or the bottom to limit the movement range of the slider 22174, prevent the slider 22174 from derailing, and ensure operational safety. A buffer pad can also be installed inside the baffle; when the slider 22174 moves to its limit position, it contacts the baffle for cushioning, avoiding rigid collisions, extending the lifespan of the slide rail 22171 and the slider 22174, and making it suitable for high-speed material handling operations.

[0131] In one possible implementation, a flexible pad is provided on the connecting surface of the connecting plate 22175 facing the product 100, and the connecting plate 22175 is connected to the product 100 through the flexible pad.

[0132] The contact surface between the connecting plate 22175 and the product 100 is covered with a flexible pad, such as silicone, sponge, or rubber. A portion of the magnetic component 22173 is embedded inside the flexible pad, or the magnetic component 22173 is placed below the flexible pad. The flexible pad ensures that elastic deformation occurs first during adsorption, and then the magnetic force completes the fastening. The flexible pad buffers contact impact and prevents the product 100 from being damaged by impact when it moves quickly to the connecting component 22172 when the magnetic force is too strong. The flexible pad can adapt to slight deformation, improving the adsorption stability of the product 100 on irregular surfaces and enhancing compatibility.

[0133] In one possible implementation, such as Figures 11-14As shown, the feeding and taping detection mechanism 231 includes a taping drive mechanism 2315, a feeding mechanism 2311, a feeding sensor 2312, a top-facing recognition camera 2313, and a light-blocking plate 2314. The taping drive mechanism 2315 drives the taping 300 to move along the packaging track. The taping drive mechanism 2315 includes a taping 300 drive motor and a rotating component. The outer periphery of the rotating component is provided with several positioning protrusions for embedding into the positioning holes 302 of the taping 300. The taping 300 drive motor drives the rotating component to rotate, thereby moving the taping 300. The feeding mechanism 2311 includes a first feeding cylinder 23111, a second feeding cylinder 23112, and a push rod 23113. The feeding mechanism 2311 drives the conveying mechanism 2217 to move the good product 100. After moving into the placement slot 301, the second feeding cylinder 23112 drives the push rod 23113 to pass through the hole of the conveying mechanism 2217 and move to above the good product 100 to form a stop. The first feeding cylinder 23111 drives the conveying mechanism 2217 to rise so that the good product 100 is separated from the conveying mechanism 2217. When the feeding sensor 2312 detects that the good product 100 is placed in the placement slot 301, it sends a feeding completion signal to the processor via the feeding mechanism 2311. The top surface recognition camera 2313 performs top surface appearance recognition on the good product 100 located at the top surface detection station. The light blocking plate 2314 is set below the top surface recognition camera 2313 to block the good product 100 located outside the top surface detection station.

[0134] Among them, such as Figure 13 , Figure 14 and Figure 18 As shown, the drive motor of the tape 300 drives the rotating component to rotate. Several positioning protrusions are provided on the outer periphery of the rotating component at equal angles. The shape of the protrusions matches the size of the positioning hole 302 of the tape 300. When the drive motor of the tape 300 drives the rotating component to rotate, the positioning protrusions are embedded in the positioning hole 302 of the tape 300. The tape 300 is forced to move step by step through mechanical engagement, ensuring that the step distance of each movement is consistent with the spacing of the placement groove 301. The motor and the rotating component can also be directly connected through a coupling or reducer to avoid transmission gaps and ensure the synchronicity and repeatability of the movement of the tape 300.

[0135] In this process, the first feeding cylinder 23111 vertically presses down on the conveying mechanism 2217 to move the product 100 above the tape 300 placement slot 301. The second feeding cylinder 23112 drives the push rod 23113 to vertically press down through the hole in the connector 22172 of the conveying mechanism 2217, abutting against the edge or surface of the product 100 to form a physical stop, preventing the product 100 from shifting when it leaves the conveying mechanism 2217. The first feeding cylinder 23111 drives the conveying mechanism 2217 to lift upwards, and the product 100 is then lifted by the push rod 23113. The limiting action 13 is separated from the conveying mechanism 2217 and is accurately placed in the placement slot 301 of the tape 300. After the unloading sensor 2312 detects that the product 100 is in place, it sends an unloading signal to the processor, triggering the tape 300 drive motor to drive the tape 300 to step to the next empty slot, ensuring that the tape 300 is completely filled and avoiding the empty slot from entering the next station or repeated unloading causing overlap. This achieves the accuracy, stability and efficiency of the tape 300 filling process, and significantly improves the reliability and yield of the automated packaging production line.

[0136] The connecting part 22172 of the conveying mechanism 2217 has a hole for the push rod 23113 to pass through. The inner diameter of the hole is slightly larger than the outer diameter of the push rod 23113 to ensure that the push rod 23113 can pass freely. The hole can be set as a cone shape that is wider at the top and narrower at the bottom. The diameter of the hole is enlarged at the entrance, for example, by adding a chamfer or a flared mouth, to facilitate the quick centering and insertion of the push rod 23113. The diameter of the hole at the bottom matches the outer diameter of the push rod 23113 to ensure the positioning accuracy of the push rod 23113 after it reaches the target position.

[0137] The push rod 23113 can be fitted with a flexible pad at its end to form a buffer and reduce mechanical stress damage to the product 100.

[0138] In addition, a top surface inspection station can be added to the packaging track of the feeding and packaging mechanism 23. The top surface recognition camera 2313 is vertically downward to photograph the top appearance of the product 100, which completes the top surface defect detection capability. Combined with the turntable mechanism 221, it realizes the closed loop of the entire process of detection-sorting-inspection-packaging. It can also further inspect before packaging to avoid empty slots or repeated feeding.

[0139] In one possible implementation, such as Figure 13 , Figure 14 and Figure 18As shown, the tape and reel packaging mechanism 232 includes an empty tape take-up reel 2322, a guide wheel 2321, a sealing tape take-up reel 2325, a tension wheel 2323, a sealing mechanism 2324, and a tape and reel 300 drive motor. One end of the tape 300 is wound around the empty tape take-up reel 2322. The tape 300 on the empty tape take-up reel 2322 is turned to the sealing track by the guide wheel 2321. The sealing tape is wound on the sealing tape take-up reel 2325. The tension wheel... 2323 is located on one side of the encapsulation tape take-up roller 2325 and is used to adjust the tension of the encapsulation tape. After the product 100 is conveyed to the encapsulation position, the sealing mechanism 2324 encapsulates the product 100 in the braided tape 300 with the encapsulation tape. The finished product braided tape take-up roller 2326 is then completed. The other end of the braided tape 300 is wrapped around the finished product braided tape take-up roller 2326. The braided tape 300 drive motor drives the finished product braided tape take-up roller 2326 to rotate and rewind the encapsulated finished product.

[0140] The empty braided tape take-up reel 2322 stores unused empty braided tape rolls 300. The empty braided tape 300 passes through the clearance groove on the operating table 12 from the empty braided tape take-up reel 2322. The guide wheel 2321 guides the empty braided tape 300 from the take-up reel to be laid flat on the sealing track, ensuring that the path of the braided tape 300 is straight and without deviation, avoiding sealing misalignment caused by twisting. The sealing tape is taken from the sealing tape take-up reel 2325 and the tension wheel 2323 adjusts the tension and covers the surface of the braided tape 300. The tension wheel 2323 keeps the tension of the sealing tape stable. After the product 100 is placed into the braided tape 300 placement groove 301, the sealing mechanism 2324 presses the sealing tape and the braided tape 300 together. The sealing process is completed by means of heat sealing heads or pressure rollers, which precisely press the sealing tape and braided tape 300 together at the position of the product 100, forming a sealed cavity in the groove 301 to enclose the product 100 and isolate it from external environmental contamination. The drive motor of the braided tape 300 drives the finished product braided tape take-up roller 2326 to rotate, and takes up the sealed finished product braided tape 300. The take-up speed is synchronized with the sealing station to ensure that the braided tape 300 is continuously conveyed without accumulation. The empty braided tape take-up roller 2322, the guide roller 2321 and the finished product braided tape take-up roller 2326 work together to adjust the direction of the braided tape 300 to ensure tight and neat take-up, avoid the braided tape 300 from being loose or misaligned, and facilitate subsequent storage or transportation.

[0141] In one possible implementation, such as Figure 1 and Figure 2 As shown, the automatic inspection and packaging system for sensor products also includes a frame 1, with a transmission and inspection mechanism 2 mounted on the frame 1. The frame 1 includes an operating table 12, a control display screen 16, and an appearance inspection screen 17, as shown. Figure 3 and Figure 4 As shown, the feeding mechanism 21, the rotary vision inspection mechanism 22, and the unloading and packaging mechanism 23 are all mounted on the operating table 12. The control display screen 16 is used for equipment operation and is connected to the processor. The appearance inspection screen 17 is used to display the inspection results of the inspection mechanism 222.

[0142] The control panel 12 serves as the core platform, integrating the feeding mechanism 21, the rotary vision inspection mechanism 22, and the unloading and packaging mechanism 23. This reduces the equipment's footprint and meets the needs of small production lines with limited space. The control display screen 16 is mounted on the frame 1 and is used for equipment start / stop, parameter setting, and status monitoring, communicating with the processor in real time. The appearance inspection screen 17 independently displays visual inspection results, such as defect images and yield statistics, facilitating quick operator verification, simplifying the human-machine interaction process, and reducing operational complexity.

[0143] In one possible implementation, such as Figure 1 and Figure 2 As shown, the frame 1 also includes a lower frame 11, an upper frame 14 and a light-blocking plate 15. The operating table 12 is set on the lower frame 11, the upper frame 14 is set on the operating table 12, the control display screen 16 and the appearance inspection screen 17 are set on the upper frame 14, and the light-blocking plate 15 is placed between the rotary vision inspection mechanism 22 and the unloading and packaging mechanism 23 to block the inspection light.

[0144] The lower frame 11 serves as a base to support the operating table 12, while the upper frame 14 is installed above the operating table 12, forming a layered structure to achieve functional zoning.

[0145] In this design, a light-blocking plate 15 is set between the rotating visual inspection area and the unloading and packaging area to form a barrier, thereby preventing interference of detection light between the recognition camera on the turntable mechanism 221 and the recognition camera on the unloading and packaging mechanism 23, ensuring that the detection light is relatively independent and ensuring recognition accuracy.

[0146] In one possible implementation, such as Figure 1 and Figure 2 As shown, the rack 1 also includes a cabinet 13 and feet 18. The cabinet 13 is mounted on the lower frame 11, and the feet 18 are mounted on the bottom of the lower frame 11 to form a support. The feet 18 can use casters.

[0147] Among them, an enclosed cabinet 13 is added to the lower shelf 11 to provide additional storage space for tools, consumables or controllers and other auxiliary equipment, thereby improving space utilization.

[0148] The lower frame 11 is equipped with feet 18 at the bottom to ensure equipment stability. Optional casters with brakes are available to enable flexible movement and fixation of the equipment. The casters support rapid transfer of the equipment across workstations. The height-adjustable feet 18 can adapt to uneven ground and ensure operational stability.
