Description

Technical Field

[0001] This application relates to the technical field of automatic carpet wrapping devices and methods, and more particularly to an automatic carpet wrapping device and method for suitcases. Background Technology

[0002] With the rapid development of the automotive industry, consumers are increasingly demanding higher standards for the comfort, sealing, and aesthetics of car interiors. As a crucial component of the car interior, trunk carpets not only need excellent sound insulation and shock absorption, but the quality of their edge and irregularly shaped sealing directly affects the overall sealing, aesthetics, and lifespan of the vehicle. Trunk carpets with irregularly shaped seals, in particular, present significant challenges in manufacturing due to their irregular structure and the high precision required for the seals to adhere to the carpet body.

[0003] Currently, the industry mostly uses manual or semi-automated methods for carpet covering of suitcases, which presents many technical problems: Firstly, during manual wrapping, operators need to manually complete processes such as positioning, dispensing, pressing, and curing the parts to be wrapped. This is labor-intensive and inefficient, making it difficult to meet the needs of large-scale mass production. Furthermore, manual operation is susceptible to fatigue and operator skill, leading to inconsistent wrapping accuracy, defects such as misaligned seals, loose fit, and uneven adhesive layers, resulting in a low product qualification rate. Secondly, most existing semi-automated equipment is designed with a single workstation, and each processing step must be carried out sequentially. It is also necessary to frequently switch between different functional equipment to process the corresponding steps. During the transfer process, the workpiece needs to be fixed and clamped repeatedly. The waiting time between processing steps is long, the equipment utilization rate is low, and this further limits the improvement of production efficiency.

[0004] Therefore, developing a device and method that can solve the above-mentioned technical problems, realize automated, high-precision, and high-efficiency wrapping of luggage carpets with irregularly shaped seals, and achieve automatic wrapping of carpets in a single clamping operation has become an urgent technical challenge in the current automotive interior processing field. Summary of the Invention

[0005] This application provides an automatic wrapping device and method for luggage carpets, which can realize the picking and placing of workpieces on unprocessed stations during the processing, and can realize the efficient and fast wrapping operation of each workpiece to be wrapped with a single clamping. It solves the problems of low efficiency of manual and semi-automatic wrapping in the prior art, poor accuracy, low product qualification rate, low equipment utilization rate and poor versatility caused by repeated clamping when switching different processing equipment to achieve different processes.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions: This application provides an automatic luggage carpet covering device, comprising: a housing; a planar rotation mechanism disposed within the housing; multiple processing stations evenly distributed on the planar rotation mechanism; positioning carriers for carrying the items to be covered, the number of positioning carriers being greater than or equal to the number of processing stations, and each processing station being detachably equipped with a positioning carrier; and a covering mechanism located directly above the planar rotation mechanism for covering the items to be covered that have rotated to its lower position; the planar rotation mechanism can drive the positioning carriers and the items to be covered on them to rotate intermittently, so that the items to be covered sequentially pass through different working areas of the covering mechanism.

[0007] This invention enables the processing of a workpiece to be coated at one station to be processed without affecting the loading and unloading of workpieces to be coated at other stations by using multiple positioning carriers set on a planar rotating mechanism. This greatly improves processing efficiency and allows a single coating device to automatically and efficiently coat multiple workpieces without the need for repeated clamping and switching between different processing equipment, which can lead to poor workpiece positioning accuracy and low processing efficiency.

[0008] The planar rotation mechanism includes: a driving component, the fixed end of which is disposed inside the housing; The turntable is connected to the output shaft of the drive unit. The rotation of the output shaft of the drive unit can brake the turntable. The machining station is set on the radial plane of the turntable.

[0009] This invention enables multiple processing steps to proceed independently without interference by intermittently rotating the output shaft of the drive component at a set angle. This greatly improves the coating effect and efficiency, and also eliminates the need for the operator to insert their body into the equipment when picking up or placing workpieces, making it safer and more convenient.

[0010] The positioning carrier includes: a mounting base, which is fixed on the processing station; a vacuum suction plate, which is set on the mounting base, the vacuum suction plate has multiple suction holes, and a vacuum generator is connected to the bottom or side of the vacuum suction plate to generate negative pressure on the surface of the vacuum suction plate to fix the object to be covered; This invention can create negative pressure in the suction holes of a vacuum suction cup by using a vacuum generator, such as a vacuum pump, which enables a firm and stable placement and fixing of the workpiece to be coated on it, greatly improving the stability of the processing operation and the portability of the installation and fixing.

[0011] The covering mechanism includes: a fixed frame, located above the planar rotating mechanism and disposed inside the chassis; The fixing plate is mounted on the fixing frame; The first mobile lifting platform is mounted on the fixed plate; A dispensing machine, mounted on the first movable lifting platform, is used to apply adhesive to a predetermined area of ​​the object to be coated.

[0012] The covering mechanism also includes: a second movable lifting platform, mounted on the fixed plate; The pressing machine, located on the second movable lifting platform, is used to press and shape the carpet fabric and the luggage carpet substrate.

[0013] The covering mechanism also includes: a third mobile lifting platform, mounted on the fixed plate; The curing machine, located on the third moving lifting platform, is used to accelerate the curing of the adhesive and improve coating efficiency and coating quality.

[0014] The dispensing machine, pressing machine, and curing machine are arranged alternately along the rotation direction of the turntable or the processing sequence. This facilitates the rapid and stable coating of three workpieces to be coated simultaneously without affecting the installation and positioning of the fourth workpiece, making it more convenient and efficient.

[0015] The first, second, and third mobile lifting platforms are all three-dimensional mobile platforms.

[0016] This invention allows for adjustment of the dispensing machine's spatial position via a first movable lifting platform, facilitating dispensing to the entire surface to be coated on the positioning carrier. A second movable lifting platform allows for adjustment of the pressing machine's spatial position, facilitating pressing and fixing of the entire surface to be coated on the positioning carrier. A third movable lifting platform allows for adjustment of the curing machine's spatial position, facilitating curing of the entire surface to be coated on the positioning carrier. This significantly improves the continuity and efficiency of the processing. The driving component is a servo motor or steering wheel, and the rotation angle of its output shaft is matched with the central angle between two adjacent processing stations. This facilitates the rotation of the positioning carrier and the workpiece to be covered at a specific angle each time, enabling continuous covering operations.

[0017] An automatic luggage carpet covering method, using the aforementioned automatic luggage carpet covering device, includes the following steps: S1. Start the curing machine and preheat to the preset working temperature; S2. Place the first part to be coated onto the positioning carrier located at the loading station and fix it in place by vacuum adsorption; S3. Start the drive unit to rotate the turntable by one station angle, so that the first part to be coated is moved to the dispensing station; S4. Start the dispensing machine and apply adhesive to the part to be coated according to the preset trajectory. At the same time, place the second part to be coated on the positioning carrier of the empty loading station. The dispensing machine performs three-dimensional movement through the first moving lifting platform to achieve adhesive application along a complex trajectory. S5. Restart the drive unit to rotate the turntable by one station angle, moving the first part to be coated to the pressing station and the second part to be coated to the dispensing station; S6. Start the pressing machine to press the carpet fabric against the luggage carpet substrate coated with adhesive. Simultaneously, perform adhesive dispensing and material loading operations at the dispensing and loading stations. The pressing machine moves vertically up and down via the second moving lifting platform to provide uniform pressing force. S7. Restart the drive unit to rotate the turntable by one station angle, so that the first part to be coated is moved to the curing station; S8. Start the curing machine to cure the pressed parts to be coated. The curing machine moves vertically up and down through the third moving lifting platform to approach or move away from the parts to be coated for curing. At the same time, the pressing station, dispensing station and loading station are pressed, dispensing and loading operations are performed in sequence. S9. Restart the drive unit to rotate the turntable by one station angle, so that the cured finished product is moved to the unloading station; S10. Remove the finished product from the unloading station and place the new part to be covered; S11. Repeat steps S3 to S10 to achieve continuous cyclic production.

[0018] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: 1. The automatic luggage carpet covering device provided in this application embodiment integrates core processes such as dispensing, pressing, and curing into the circumferential direction of the same machine by setting up a planar rotating mechanism and evenly distributing multiple processing stations on it. Combined with the intermittent rotation control of the drive component, the automatic flow of the parts to be covered between various processes is realized, eliminating the need for manual handling and forming a highly efficient and compact automated production line, which greatly shortens the production cycle and improves production efficiency.

[0019] 2. The positioning carrier adopts a vacuum suction plate structure, which uses the negative pressure generated by the vacuum generator to adsorb and fix the parts to be coated. This ensures that the position of the workpiece remains absolutely stable during high-speed rotation of the turntable and operations such as dispensing and pressing, avoiding processing deviations caused by workpiece displacement, thereby significantly improving product consistency and pass rate.

[0020] 3. The coating mechanism integrates a dispensing machine, a pressing machine, and a curing machine, each driven by an independent three-dimensional moving platform. This not only enables precise control of the adhesive application trajectory, such as for accurate coating on the complex irregular edges of luggage carpets, but also ensures the uniformity of the pressing force. Furthermore, the curing machine rapidly cures the adhesive, such as through infrared heating or ultraviolet curing, reducing the natural curing time that originally required several hours to tens of seconds. This significantly shortens the production cycle and reduces the backlog of work-in-process.

[0021] 4. By precisely controlling the intermittent rotation of the turntable and the timing of operations at each station, multiple actions such as loading, dispensing, pressing, curing, and unloading are executed in parallel. For example, while the pressing machine is working, the dispensing machine can dispense adhesive to another workpiece, and the operator can also load materials. This highly parallel operation mode maximizes the overall utilization of the equipment and significantly increases output per unit time.

[0022] 5. Reduced human intervention. Except for loading and unloading operations, dispensing, pressing, curing, and workpiece transfer are all completed automatically by the equipment, effectively reducing the uncertainty caused by manual operation, lowering the labor intensity and skill requirements of operators, and avoiding direct contact between operators and chemicals such as adhesives, thus improving the working environment and reducing occupational health risks.

[0023] 6. The device features a compact structure, high integration, and a small footprint. Compared to the traditional distributed layout with multiple independent workstations, this device integrates all processes into a single chassis, significantly saving valuable factory space. Furthermore, since the actions of each workstation are coordinated by a central control system, it facilitates digital management and production data traceability.

Detailed Implementation

[0027] The terms "first," "second," and "third," etc., used in this application specification and accompanying drawings are used to distinguish different objects, not to limit a specific order.

[0028] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides an automatic luggage carpet covering device. The device includes a housing 100, which is usually a closed frame structure that serves as a support and protection. The upper part of the housing is provided with an openable and closable transparent observation and sealing door, which allows the operator to observe the processing of the products inside the housing 100 and handle some emergencies. The main functional components are also located inside the housing 100.

[0030] A planar rotation mechanism 200 is fixedly mounted on the bottom plate inside the chassis 100. The planar rotation mechanism 200 includes a servo motor as a drive element 210 and a turntable 220. The fixed end of the servo motor is mounted on the bottom plate of the chassis 100 via a motor mount, and its output shaft is vertically upward. The center of the turntable 220 is fixed to the output shaft of the servo motor via a key connection or flange connection, thereby enabling it to be driven by the servo motor for precise intermittent rotation. In this embodiment, four processing stations 300 are evenly distributed circumferentially on the turntable 220. The central angle between two adjacent processing stations 300 is 90 degrees, therefore the angle of each rotation of the servo motor is set to 90 degrees to achieve precise switching of the stations.

[0031] Each processing station 300 can be detachably mounted with a positioning carrier 400. The total number of positioning carriers 400 is four, equal to the number of processing stations 300. For example... Figure 3 and Figure 4 As shown, each positioning carrier 400 includes a mounting base 410 and a vacuum suction plate 420. The mounting base 410 is fixed to the processing station 300 of the turntable 220 by bolts. The vacuum suction plate 420 is made of high-strength aluminum alloy, and its surface is machined with contour grooves according to the outline shape of the luggage carpet substrate to be covered, and multiple tiny suction holes 421 are densely distributed in the contour grooves and edge areas. A vacuum generator is connected to the bottom or side of the vacuum suction plate 420, preferably a vacuum pump. When the item to be covered, i.e., the luggage carpet substrate, is placed on the vacuum suction plate 420, the vacuum generator is activated, sucking the air in the suction holes 421 to form a negative pressure, thereby firmly adsorbing and fixing the substrate. This fixing method is stable and reliable and will not cause scratches to the surface of the substrate.

[0032] Directly above the turntable 220, a covering mechanism 500 is installed inside the chassis 100. The covering mechanism 500 includes a gantry-type fixed frame 510, the uprights of which are fixed to the base plate of the chassis 100, and the crossbeam spans above the turntable 220. A fixed plate 520 is horizontally mounted on the fixed frame 510. On the fixed plate 520, along the rotation direction of the turntable 220, for example, clockwise, three independent moving lifting platforms are sequentially mounted: a first moving lifting platform 530, a second moving lifting platform 550, and a third moving lifting platform 570. Each moving lifting platform is a high-precision three-dimensional moving platform; for example, an XYZ three-axis motion platform composed of a linear motor module and a servo electric cylinder can be selected, which can precisely control the position and trajectory of the end effector in space.

[0033] A dispensing machine 540 is installed on the first mobile lifting platform 530. The dispensing machine 540 can be a screw-type dispensing machine 540 with a precision metering valve, or it can be a jet valve dispensing system of the prior art, used to accurately apply adhesives such as hot melt adhesive or reactive polyurethane hot melt adhesive to a predetermined area of ​​the luggage carpet substrate.

[0034] A pressing machine 560 is installed on the second mobile lifting platform 550. The pressing machine 560 can be a shaping device with a rotating pressing roller, which is a common technology.

[0035] Of course, in other embodiments, the press 560 may also consist of a pressure plate driven by a servo-driven electric cylinder and a contouring press head located below the pressure plate. The shape of the contouring press head matches the contour of the carpet fabric, and its surface is covered with a silicone cushioning layer. During pressing, the press 560 descends via a second movable lifting platform 550 to set pressure and press the carpet fabric onto the adhesive-coated substrate, ensuring a tight fit between the fabric and the substrate without air bubbles. A curing machine 580 is installed on the third mobile lifting platform 570. In this embodiment, the curing machine 580 uses an infrared heating curing device, such as an infrared radiator. The curing machine 580 is lowered to near the surface of the workpiece via the third mobile lifting platform 570, and uses infrared radiation energy to quickly heat the adhesive layer, so that the adhesive can complete the curing reaction in a short time and achieve the final bonding strength.

[0036] The aforementioned dispensing machine 540, pressing machine 560 and curing machine 580 are arranged sequentially at intervals in the circumferential direction of the turntable 220, corresponding to the four processing stations 300, forming the dispensing station, pressing station and curing station respectively, and the remaining processing station 300 is used as the loading / unloading station.

[0037] Example 2 This embodiment is basically the same as Embodiment 1, except that, in order to further improve production efficiency and adapt to the process requirements of different products, the number of processing stations 300 on the turntable 220 is set to six. Correspondingly, the number of positioning carriers 400 is also six. In the coating mechanism 500, in addition to the dispensing machine 540, pressing machine 560, and curing machine 580, an auxiliary station for online cleaning or inspection is added. The drive unit 210 uses a high-precision direct drive motor to achieve smoother and faster station switching. The positions of the dispensing machine 540, pressing machine 560, and curing machine 580 can be rearranged according to the process flow. For example, for complex products that require secondary pressing or segmented curing, two pressing stations or two curing stations can be set up, and the number of corresponding mobile lifting platforms and working heads is also increased accordingly. This embodiment further expands the applicability and production capacity of the device.

[0038] Example 3 The difference between this embodiment and the previous embodiment lies in the optimization of the material and connection method of the positioning carrier 400. To accommodate different models of luggage carpets, the mounting base 410 of the positioning carrier 400 is connected to the turntable 220 using a quick-change mechanism, such as a pneumatic clamp or positioning pin with an eccentric locking device. This way, when changing product models, only the entire positioning carrier 400 assembly needs to be replaced, without disassembling the vacuum lines and electrical wiring, achieving rapid production changeover and greatly improving the equipment's flexible production capabilities. The vacuum suction plate 420 is made of engineering plastics, such as bakelite or POM, and is CNC machined, ensuring strength while reducing weight, which helps reduce the rotational inertia of the turntable 220 and improves dynamic response performance.

[0039] The working principle and usage method are as follows: This embodiment also provides an automatic method for covering a suitcase carpet using the above-described device, such as... Figure 5 As shown, the specific steps are as follows: First, the equipment is powered on and the control system is started. The operator sets the process parameters such as dispensing trajectory, pressing pressure, curing temperature, and time on the control panel. The curing machine 580 is then started to preheat until it reaches the preset working temperature.

[0040] Initially, all four positioning carriers 400 are in an empty state. The operator places the first suitcase carpet substrate to be covered onto the positioning carrier 400 at the loading / unloading station. After the substrate is in place, the sensor switch is triggered, and the vacuum generator automatically starts, firmly adhering the substrate through the adsorption holes 421 on the vacuum suction plate 420.

[0041] The control system issues a command, the servo motor starts, and drives the turntable 220 to rotate precisely 90 degrees. At this time, the first substrate moves with the turntable 220 to the dispensing station, located directly below the dispensing machine 540.

[0042] The first mobile lifting platform 530 drives the dispensing machine 540 to move along a preset three-dimensional trajectory, precisely applying hot melt adhesive to the coating area of ​​the substrate. At the same time, the operator places the second substrate to be coated onto the positioning carrier 400 in the empty loading / unloading station, and fixes it by vacuum adsorption.

[0043] After dispensing is complete, the servo motor drives the turntable 220 to rotate 90 degrees again. At this time, the first substrate, already coated with adhesive, moves to the pressing station, while the second substrate, not yet coated with adhesive, moves to the dispensing station. The operator or the automatic feeding mechanism places the pre-cut carpet fabric onto the first substrate located at the pressing station. Subsequently, the second moving lifting platform 550 lowers the pressing machine 560, and the contour pressing head presses the fabric and substrate together with the set pressure. Simultaneously, the dispensing machine 540 at the dispensing station dispenses adhesive onto the second substrate, and the operator places the third substrate at the loading / unloading station.

[0044] After pressing is completed, the servo motor drives the turntable 220 to rotate 90 degrees for the third time. At this point, the first substrate, having been pressed, has moved to the curing station; the second substrate, having been dispensed, has moved to the pressing station; and the third substrate, without dispensing, has moved to the dispensing station. The third moving lifting platform 570 lowers the curing machine 580 to perform infrared heating curing on the first substrate. Simultaneously, the pressing and dispensing stations perform pressing and dispensing operations in parallel, while the loading / unloading station places the fourth substrate.

[0045] After curing, the servo motor drives the turntable 220 to rotate 90 degrees for the fourth time. At this point, the first substrate has completed curing and becomes a finished product, moving to the loading / unloading station. The operator removes the finished product and places the fifth substrate to be coated, starting the next cycle.

[0046] This process repeats itself; each rotation of turntable 220 completes all processes for one finished product, which is then removed, while a new workpiece is simultaneously fed into the production line. This parallel operation method enables continuous, efficient, and automated production of luggage carpet coverings. Throughout the process, the rotation angle of the servo motors, the movement of each mobile lifting platform, the opening and closing of the dispensing valves, the pressing pressure, and the curing power are all precisely coordinated and controlled by a central controller, such as a programmable logic controller (PLC), ensuring the accurate timing of actions at each workstation.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
