Description

Technical Field

[0001] The present invention relates to the field of in-vehicle central control screen production, and in particular, to an automatic production line for in-vehicle central control screens. Background Art

[0002] An in-vehicle central control screen refers to a touch screen or display screen installed on the center console of an automobile, which is used to display various information of the vehicle and control certain functions of the vehicle. It usually has functions such as navigation, entertainment, vehicle information display and control. In the later stage of the assembly of the in-vehicle central control screen, multiple components need to be assembled. Components such as display screens, PCBs, FPCs, shielding covers and rear covers all need to be assembled, and some components such as display screens and shielding covers need to be fixed by screws after assembly. Since the number of components to be assembled is large and the processes are relatively independent and complex, the assembly and fixation of each component need to be achieved manually. For example, the PCB needs to be assembled manually and then fixed with screws, resulting in a long, complex and discontinuous overall production process, low production efficiency, and being not conducive to mass production of products. Summary of the Invention

[0003] In view of this, the present invention provides an automatic production line for in-vehicle central control screens that can reduce the number of workers and the operation difficulty of workers, and can achieve continuous production of products.

[0004] The object of the present invention is achieved by the following technical solutions:

[0005] An automatic production line for in-vehicle central control screens, comprising: a carrier conveyor line and two carrier lifting devices; the carrier conveyor line includes an upper conveyor line and a lower conveyor line with opposite conveying directions, the upper conveyor line is used to convey carriers carrying products to be assembled, and the lower conveyor line is used to convey empty carriers; the two carrier lifting devices are respectively located at both ends of the carrier conveyor line and are used to realize the transfer of carriers between the upper conveyor line and the lower conveyor line; on one side of the carrier conveyor line and along the conveying direction of the upper conveyor line, there are successively arranged a loading table, a display screen and PCB assembly device, an FPC insertion and detection device, a shielding cover assembly device, a rear cover assembly device, a buckle assembly device and an unloading table; wherein, the carrier conveyor line includes three main line bodies connected in sequence, and the three main line bodies are arranged in a continuous turning manner, and adjacent two main line bodies are connected by a corner device.

[0006] In the above technical solution, when assembling the in-vehicle central control screen, the main body of the central control screen to be assembled is placed on the carrier located on the upper conveyor line. The upper conveyor line sequentially conveys the carrier to the display screen and PCB assembly device, FPC insertion and detection device, shielding cover assembly device, rear cover assembly device, and buckle assembly device, thereby completing the assembly and fixation of the central control screen display screen and PCB, the insertion of the FPC, the assembly and fixation of the shielding cover, the assembly and fixation of the rear cover, and the assembly of the buckle, etc. After the assembly is completed, the product is taken off, and the empty carrier is transferred to the lower conveyor line through the carrier lifting device. The lower conveyor line conveys the product back to the starting end of the upper conveyor line, thereby realizing the return of the carrier and forming a processing cycle.

[0007] Therefore, from feeding to discharging of the entire production line, the assembly between each link can be continuously carried out through the action of the carrier conveyor line, significantly improving the production efficiency, reducing manual intervention, reducing the possibility of human errors, and ensuring the stability and consistency of product quality. And through the efficient transfer of the carrier between the upper and lower conveyor lines by two carrier lifting devices, the separation and recycling of the products to be assembled and the empty carriers are realized, effectively improving the material flow efficiency and space utilization rate of the production line and reducing the waiting time. In addition, the three main line bodies are connected by the corner device to form a continuously turning layout, which not only saves the floor area, but also makes the production line layout more compact and reasonable, improving the space utilization rate of the production site.

[0008] Optionally, in a possible implementation manner, the carrier lifting device includes a lifting frame, a lifting driving member provided on the lifting frame, and a lifting wire body provided at the output end of the lifting driving member. The lifting driving member is used to drive the lifting wire body to dock with the upper conveyor line or the lower conveyor line.

[0009] In the above technical solution, the lifting wire body can receive an empty or full carrier, and then the lifting driving member can drive the lifting of the lifting wire body so that the carrier can be transferred to the upper conveyor line or the lower conveyor line. The structure is simple, and the movement speed and position of the lifting wire body can be accurately controlled by the lifting driving member, which can ensure the fast and stable docking of the carrier between the upper conveyor line and the lower conveyor line, greatly improving the efficiency and stability of the logistics transportation.

[0010] Optionally, in a possible implementation manner, the corner device includes a corner frame and two sets of rotating components spaced on the corner frame. The rotating component includes a rotating plate, a rotating wire body installed on the rotating plate, and a rotating driving member for driving the rotation of the rotating plate.

[0011] In the above technical solution, the corner device is provided to change the conveying direction of the vehicle. The two sets of rotating components are respectively matched with the upper conveying line and the lower conveying line. When operating, the vehicle is carried by the rotating line body, and then the rotating line body is driven to rotate by the rotating driving member to change the direction of the vehicle. The structure is simple and effective, and the independent driving mechanism of the rotating component allows different conveying lines to be flexibly adjusted according to actual needs, such as speed matching, direction switching, etc., so as to adapt to diverse production scenarios.

[0012] Optionally, in a possible implementation manner, the display screen and PCB assembly device includes a first manual assembly table and a PCB locking mechanism arranged in sequence; the shielding cover assembly device includes a second manual assembly table and a shielding cover locking mechanism arranged in sequence; the rear cover assembly device includes a third manual assembly table, a rear cover front locking mechanism and a rear cover side locking mechanism.

[0013] In the above technical solution, automated or semi-automated mechanisms are adopted in key locking steps, such as the PCB locking mechanism, the shielding cover locking mechanism, etc., to ensure the accuracy and consistency of locking. At the same time, manual assembly tables are retained, such as the first manual assembly table, the second manual assembly table, and the third manual assembly table, for more complex assembly operations or handling special situations. This combination of manual and automation gives full play to the efficiency advantages of automated equipment while retaining the flexibility and adaptability of manual labor.

[0014] Optionally, in a possible implementation manner, the loading table, the first manual assembly table, the second manual assembly table, the third manual assembly table, and the unloading table have the same structure, and each includes a fixed frame, a support frame body arranged on the fixed frame, and multiple sets of material frames. The multiple sets of material frames are respectively installed on the support frame body through adjustable components.

[0015] In the above technical solution, since all stations adopt the same basic structure design, operators do not need to re-adapt to a new working environment or tool layout when transferring from one station to another. When the production process on the production line changes, by simply adjusting the position, quantity or type of the material frames, the new production requirements can be quickly adapted. In addition, the adjustable setting of the material frames can also make it more convenient to access and manage materials, reduce the chaos at the work site, and enable the production to proceed orderly and stably.

[0016] Optionally, in a possible implementation, the PCB locking mechanism, the shielding cover locking mechanism and the back cover front locking mechanism are the same, and all include a first locking frame, a first multi-axis manipulator arranged on the first locking frame, a first screw locking machine arranged at the output end of the first multi-axis manipulator, a detection table for detecting torque and locking depth, and a first visual inspection component arranged above the first screw locking machine, and the first screw locking machine is vertically arranged.

[0017] In the above technical solution, the PCB, shielding cover and the front of the back cover all need to be fixed with screws after manual assembly, and the required direction of the screwing is consistent, so it can be achieved using the same structure, and the same mechanism configuration means that a unified control system can be used to manage these locking tasks, and only different programs need to be called, which reduces compatibility issues between equipment and improves overall production efficiency and stability.

[0018] Optionally, in a possible implementation, the rear cover side locking mechanism includes a second locking frame, and a multi-axis manipulator, a rotating platform and a second screw locking machine arranged on the second locking frame, the output end of the multi-axis manipulator is provided with a grasping assembly for clamping the carrier, and the second screw locking machine is horizontally arranged.

[0019] In the above technical solution, the rear cover side locking mechanism adopts a multi-axis manipulator, which has extremely high flexibility and precision. The multi-axis design enables the manipulator to perform complex motion trajectories, including translation, rotation, tilt and other actions, so as to adapt to the locking requirements of different positions and angles on the side of the rear cover. The setting of the rotating platform allows the locked rear cover to be accurately rotated on the horizontal plane, and with the movement of the multi-axis manipulator, accurate locking can be achieved at any position on the side of the rear cover.

[0020] Optionally, in a possible implementation, the FPC insertion and detection device includes an FPC frame, a horizontal linear module arranged on the FPC frame, a vertical linear module arranged at the output end of the horizontal linear module, and an FPC detection camera arranged at the output end of the vertical linear module, and the moving direction of the horizontal linear module is parallel to the conveying direction of the carrier conveying line.

[0021] In the above technical solution, the combined use of the horizontal linear module and the vertical linear module realizes the precise positioning of the FPC inspection camera in three-dimensional space. The horizontal linear module ensures that the FPC inspection camera can move in a direction parallel to the carrier conveyor line, while the vertical linear module allows the device to move in the vertical direction. In this way, after the FPC is plugged in, it is possible to effectively check whether the FPC is assembled in place, ensuring that the assembly effect can be fed back in time.

[0022] Optionally, in a possible implementation, the buckle assembly device includes a buckle rack, a grasping manipulator disposed on the buckle rack, and a vibrating disk for providing buckles, and a rotatable elastic jaw is provided at the output end of the grasping manipulator.

[0023] In the above technical solution, the design of the rotatable elastic jaw equipped on the grasping manipulator enables it to accurately and flexibly grasp and place buckles of various shapes and sizes. This not only ensures the accuracy of buckle assembly but also improves the adaptability of the device to different types of buckles, reducing the assembly difficulty caused by differences in buckle shapes. The vibrating disk, as a buckle supply device, can continuously and stably supply buckles to the grasping manipulator. With the quick response and precise operation of the manipulator, the entire buckle assembly process realizes efficient automated operation, significantly improving production efficiency.

[0024] Optionally, in a possible implementation, two adjacent line bodies are perpendicular to each other, and the three line bodies together enclose a "U"-shaped production line with a square operation space, and several operating platforms are provided in the square operation space.

[0025] In the above technical solution, by designing the three line bodies to be perpendicular to each other and enclosing a "U"-shaped production line, not only a compact square operation space is formed, but also the space utilization rate of the production workshop is greatly optimized, which helps to achieve smooth connection of the production process, provides a closer working environment for operators, shortens the moving distance between different processes, and also facilitates operators to monitor and manage the entire production process.

[0050] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0052] Please refer to Figure 1, this embodiment provides an automatic production line for vehicle-mounted central control screens, including: a carrier conveyor line 1 and two carrier lifting devices 2; the carrier conveyor line 1 includes an upper conveyor line 11 and a lower conveyor line 12 with opposite conveying directions. The upper conveyor line 11 is used to convey carriers carrying products to be assembled, and the lower conveyor line 12 is used to convey empty carriers; the two carrier lifting devices 2 are respectively located at both ends of the carrier conveyor line 1 and are used to transfer carriers between the upper conveyor line 11 and the lower conveyor line 12; on one side of the carrier conveyor line 1 and along the conveying direction of the upper conveyor line 11, there are successively arranged a loading platform 3, a display screen and PCB assembly device 4, an FPC insertion and detection device 5, a shielding cover assembly device 6, a rear cover assembly device 7, a buckle assembly device 8, and an unloading platform 9; among them, the carrier conveyor line 1 includes three main line bodies connected in sequence, and the three main line bodies are arranged in a continuous turning manner, and adjacent two main line bodies are connected by a corner device 10.

[0053] When assembling the vehicle-mounted central control screen, place the main body of the central control screen to be assembled on the carrier located on the upper conveyor line 11. The upper conveyor line 11 conveys the carrier to the display screen and PCB assembly device 4, the FPC insertion and detection device 5, the shielding cover assembly device 6, the rear cover assembly device 7, and the buckle assembly device 8 in sequence, so as to complete the assembly and fixation of the central control screen display screen and PCB, the insertion of the FPC, the assembly and fixation of the shielding cover, the assembly and fixation of the rear cover, and the assembly of the buckle and other processes. After the assembly is completed, remove the product, and the empty carrier is transferred to the lower conveyor line 12 through the carrier lifting device 2. The lower conveyor line 12 conveys the product back to the starting end of the upper conveyor line 11, thereby realizing the return flow of the carrier and forming a processing cycle.

[0054] Therefore, from loading to unloading in the entire production line, the assembly between each link can be carried out continuously and uninterruptedly through the action of the carrier conveyor line 1, significantly improving the production efficiency, reducing manual intervention, reducing the possibility of human errors, and ensuring the stability and consistency of product quality. And through the two carrier lifting devices 2, the carriers are efficiently transferred between the upper and lower conveyor lines 12, realizing the separation and recycling of the products to be assembled and the empty carriers, effectively improving the material flow efficiency and space utilization rate of the production line, and reducing the waiting time. In addition, the three main line bodies are connected by the corner device 10 to form a continuous turning layout, which not only saves the floor area, but also makes the production line layout more compact and reasonable, improving the space utilization rate of the production site.

[0055] Please refer to Figure 2 and Figure 3 , in this embodiment, the carrier lifting device 2 includes a lifting frame 21, a lifting driving member 22 provided on the lifting frame 21, and a lifting wire body 23 provided at the output end of the lifting driving member 22. The lifting driving member 22 is used to drive the lifting wire body 23 to be docked with the upper conveyor line 11 or the lower conveyor line 12.

[0056] The lifting line 23 of this embodiment can receive empty or fully loaded carriers, and then the lifting line 23 can be driven to rise and fall through the lifting drive 22, so that the carrier can be transferred to the upper conveyor line 11 or the lower conveyor line 12. The structure is simple, and the movement speed and position of the lifting line 23 can be accurately controlled by the lifting drive 22, which can ensure the rapid and smooth docking of the carrier between the upper conveyor line 11 and the lower conveyor line 12, thereby greatly improving the efficiency and stability of logistics transportation.

[0057] Specifically, the lifting line body 23 is a conventional conveyor belt structure, which generally includes a frame, a conveyor belt and a motor, and the specific structure is not described here. The lifting drive member 22 includes a lifting cylinder 221 fixedly installed at the bottom of the lifting frame 21, a sprocket module 222 provided at the output end of the lifting cylinder 221, and a chain 223, one end of the chain 223 is fixedly connected to the bottom of the lifting frame 21, and the other end is connected to the mobile frame 224, and the chain 223 is linked to the sprocket module 222, and the lifting line body 23 is installed on the mobile frame 224, and the mobile frame 224 is connected to the lifting frame 21 through the first slide rail slider module 225. In this way, when the lifting cylinder 221 is in operation, the extension distance of the chain 223 can be driven by the sprocket to drive the lifting of the mobile frame 224. On the one hand, this lifting structure can effectively save space and facilitate assembly and maintenance. On the other hand, the lifting line 23 can always apply downward gravity to the chain 223. In conjunction with the sprocket module 222, the chain 223 can always be in a taut state, thereby ensuring the stability and driving efficiency of the entire lifting structure.

[0058] Please refer to Figure 4 and Figure 5 In this embodiment, the corner device 10 includes a corner frame 101, and two sets of rotating components arranged at intervals on the corner frame 101, and the rotating components include a rotating plate 102, a rotating line body 103 installed on the rotating plate 102, and a rotating driving member 104 for driving the rotating plate 102 to rotate. The two sets of rotating components are arranged at intervals in the vertical direction, and are respectively connected to the upper conveying line 11 and the lower conveying line 12 and operate independently.

[0059] The corner device 10 is configured to change the conveying direction of the carrier. The two sets of rotating components are matched with the upper conveyor line 11 and the lower conveyor line 12 respectively. During operation, the carrier is carried by the rotating line body 103, and then the rotating line body 103 is driven to rotate by the rotating driving member 104 to change the direction of the carrier. The structure is simple and effective, and the independent driving mechanism of the rotating component allows different conveyor lines to be flexibly adjusted according to actual needs, such as speed matching, direction switching, etc., so as to adapt to diverse production scenarios.

[0060] Specifically, the rotating line body 103 has a conventional conveyor belt structure. There are two mounting plates 105 corresponding to the two groups of rotating drive members 104 on the corner bracket. The rotating drive members 104 are arranged on the mounting plates 105. A cylindrical card seat 1021 is provided at the bottom of the rotating plate 102, and a card hole 1051 matching the card seat 1021 is provided on the mounting plate 105. The card seat 1021 can be rotatably clamped in the card hole 1051. The rotating drive member 104 includes a rotating drive cylinder 1041, a sliding seat 1042 connected to the output end of the rotating drive cylinder 1041, a rack 1043 fixedly arranged on the sliding seat 1042, and a gear 1044 fixedly sleeved on the outer periphery of the card seat 1021. The rack 1043 is meshed and connected with the gear 1044. The sliding seat 1042 is slidably connected to the mounting plate 105 through a second slide rail-slider module 1045. When the rotating drive cylinder 1041 operates, by driving the movement of the sliding seat 1042, the rotation of the card seat 1021 can be driven, thereby realizing the rotation function of the rotating line body 103. Its structure is stable, the response is rapid, and the gear 1044-rack 1043 structure has a certain self-locking function.

[0061] In addition, two limit seats 106 are further provided on the mounting plate 105. The two limit seats 106 are located on the movement track of the sliding seat 1042 and are used to limit the movement range of the sliding seat 1042, thereby limiting the rotation angle of the rotating line body 103. During actual use, the rotation angle range of the rotating line body 103 can be adjusted according to actual needs by adjusting the distance between the two limit seats 106, thereby improving the applicability, and the adjustment method is simple and convenient.

[0062] Please refer to Figure 1 , in this embodiment, the display screen and PCB assembly device 4 includes a first manual assembly table 41 and a PCB locking mechanism 42 arranged in sequence; the shielding cover assembly device 6 includes a second manual assembly table 61 and a shielding cover locking mechanism 62 arranged in sequence; the rear cover assembly device 7 includes a third manual assembly table 71, a rear cover front locking mechanism 72 and a rear cover side locking mechanism 73.

[0063] In this embodiment, automated or semi-automated mechanisms are adopted in key locking steps, such as the PCB locking mechanism 42, the shielding cover locking mechanism 62, etc., to ensure the accuracy and consistency of locking. At the same time, manual assembly tables are retained, such as the first manual assembly table 41, the second manual assembly table 61, and the third manual assembly table 71, for more complex assembly operations or handling special situations. This combination of manual and automation gives full play to the efficiency advantages of automated equipment while retaining the flexibility and adaptability of manual labor.

[0064] Please refer to Figure 6 and Figure 7, in this embodiment, the loading table 3, the first manual assembly table 41, the second manual assembly table 61, the third manual assembly table 71, and the unloading table 9 have the same structure, which all include a fixed frame 31, a support frame 32 provided on the fixed frame 31, and multiple sets of material frames 33. The multiple sets of material frames 33 are respectively installed on the support frame 32 through adjustable components 34.

[0065] Since all stations adopt the same basic structure design, operators do not need to re - adapt to a new working environment or tool layout when transferring from one station to another. When the production process on the production line changes, by simply adjusting the position, quantity, or type of the material frame 33, it can quickly adapt to the new production requirements. In addition, the adjustable setting of the material frame 33 can also make it more convenient to access and manage materials, reduce the chaos at the work site, and enable the production to proceed orderly and stably.

[0066] Specifically, the adjustable component 34 includes two adjusting rods 341 arranged at intervals and two support members symmetrically arranged on the two adjusting rods 341. The two ends of the adjusting rod 341 are respectively movably arranged on the support frame 32 through adjusting blocks 342. The support member includes a limiting plate 343 and two sections of support bars 344. A plurality of pulleys (not shown in the figure) are rotatably installed on both sections of the support bars 344. The plurality of pulleys are spaced along the length direction of the support bar 344. A rotating column 345 is provided on one side or both sides of the pulley. The rotating column 345 extends outside the support bar 344. A plurality of card slots 3431 matching the rotating column 345 are provided on the limiting plate 343. The card slots 3431 can be clamped on the rotating column 345 to connect the two sections of support bars 344 into a whole. The support bar 344 is installed on the adjusting rod 341 through a clamping member 346. The clamping member 346 is provided with a groove matching the rotating column 345. One end of the clamping member 346 is detachably fixed on the adjusting rod 341, and the other end is clamped on the rotating column 345.

[0067] The above - mentioned setting of the adjustable component 34, through the setting of two adjusting rods 341 and two support members, jointly forms a structure for placing the material frame 33. Among them, the support member is composed of two sections of support bars 344 and a limiting plate 343. The length of the base formed by the two sections of support bars 344 can be adjusted arbitrarily, and after adjustment, it is fixed by the limiting plate 343. In this way, more material frames 33 or material frames 33 of different sizes can be placed. In addition, the relative positions of the two adjusting rods 341 can also be adjusted. By adjusting their positions, the placement angle of the material frame 33 can be synchronously adjusted, making it more flexible to use.

[0068] Please refer to Figure 8, in this embodiment, the PCB attachment mechanism 42, the shielding cover attachment mechanism 62, and the front cover attachment mechanism 72 of the rear cover have the same structure, all including a first attachment frame 421, a first multi-axis manipulator 422 provided on the first attachment frame 421, a first screw locking machine 423 provided at the output end of the first multi-axis manipulator 422, a detection table 424 for detecting torque and attachment depth, and a first vision detection component 425 provided above the first screw locking machine 423. The first screw locking machine 423 is vertically arranged. Among them, the detection table 424 includes a torque tester for detecting the torque of the locked screw and a floating height detection block for detecting the attachment depth.

[0069] The PCB, the shielding cover, and the front of the rear cover all need to be fixed with screws after manual assembly, and the required directions for screwing are the same. Therefore, the same structure can be used to achieve this, and the same mechanism configuration means that a unified control system can be used to manage these attachment tasks. Only by calling different programs can the compatibility problems between devices be reduced, and the overall production efficiency and stability can be improved.

[0070] Please refer to Figure 9 and Figure 10 , in this embodiment, the side cover attachment mechanism 73 of the rear cover includes a second attachment frame 731, and a second multi-axis manipulator 732, a rotating platform 733, and a second screw locking machine 734 provided on the second attachment frame 731. A grasping component 735 for clamping the carrier is provided at the output end of the second multi-axis manipulator 732, and the second screw locking machine 734 is horizontally arranged.

[0071] The side cover attachment mechanism 73 of the rear cover uses a multi-axis manipulator, which has extremely high flexibility and precision. The multi-axis design enables the manipulator to execute complex motion trajectories, including various actions such as translation, rotation, and tilting, so as to adapt to the attachment requirements at different positions and angles on the side of the rear cover. The setting of the rotating platform 733 enables the rear cover to be attached to be accurately rotated on the horizontal plane. Cooperating with the movement of the multi-axis manipulator, accurate attachment at any position on the side of the rear cover can be achieved.

[0072] Specifically, the grasping component 735 includes a grasping plate and a plurality of jaw cylinders fixed on the grasping plate. The jaw cylinders can be set to four and are arranged in a rectangular array, respectively used to grasp the four corners of the carrier. The rotating platform 733 includes a rotating seat 7331 rotatably mounted on the locking frame and a seat driving cylinder 7332 for driving the rotation of the rotating seat 7331. Among them, a plurality of rotating pressing cylinders 7333 are provided on the rotating seat 7331, and a pressing block 7334 is provided at the output end of the rotating pressing cylinder 7333. The rotating pressing cylinder 7333 has the functions of rotation and pressing. When the second multi-axis manipulator 732 transfers the carrier to the rotating seat 7331, it can be pressed through the action of a plurality of rotating pressing cylinders 7333 and pressing blocks 7334 to avoid offset during screw driving.

[0073] It should be noted that the structures of the first screw locking machine 423 and the second screw locking machine 734 in this embodiment are the same and are existing conventional devices, which generally include an electric screwdriver, a displacement sensor, a color CCD system, and a linear driving mechanism. The specific structure will not be elaborated here.

[0074] Please refer to Figure 11 , in this embodiment, the FPC insertion and detection device 5 includes an FPC frame 51, a horizontal linear module 52 provided on the FPC frame 51, a vertical linear module 53 provided at the output end of the horizontal linear module 52, and an FPC detection camera (not shown in the figure) provided at the output end of the vertical linear module 53. The moving direction of the horizontal linear module 52 is parallel to the conveying direction of the carrier conveying line 1.

[0075] In this embodiment, through the combined use of the horizontal linear module and the vertical linear module 53, precise positioning of the FPC detection camera in three-dimensional space is achieved. The horizontal linear module 52 ensures that the FPC detection camera can move along a direction parallel to the carrier conveying line 1, while the vertical linear module 53 allows the device to move in the vertical direction. In this way, after the FPC is inserted, it can effectively check whether the FPC is assembled in place and ensure timely feedback on the assembly effect.

[0076] Please refer to Figure 12 , in this embodiment, the buckle assembly device 8 includes a buckle frame 81, a buckle grasping manipulator 82 provided on the buckle frame 81, and a vibrating disk 83 for providing buckles. A rotatable elastic jaw 84 is provided at the output end of the buckle grasping manipulator 82. Among them, the elastic jaw 84 is provided with a groove matching the buckle, and the buckle can be fixed in the groove by squeezing the buckle to achieve the grasping of the buckle.

[0077] The rotatable elastic jaws 84 equipped on the clamping manipulator 82 are designed to enable precise and flexible grasping and placement of fasteners of various shapes and sizes. This not only ensures the accuracy of fastener assembly but also improves the adaptability of the device to different types of fasteners, reducing the assembly difficulty caused by differences in fastener shapes. The vibrating bowl 83, as a supply device for fasteners, can continuously and stably supply fasteners to the clamping manipulator 82. With the quick response and precise operation of the manipulator, the entire fastener assembly process realizes highly efficient automated operation, significantly improving production efficiency.

[0078] Please refer to Figure 1 , in this embodiment, two adjacent wire bodies are perpendicular to each other, and the three wire bodies together enclose a "U"-shaped production line with a square operation space. There are several operating tables 13 in the square operation space. By designing the three wire bodies to be perpendicular to each other and enclosing a "U"-shaped production line, this embodiment not only forms a compact square operation space but also greatly optimizes the space utilization rate of the production workshop, helps to achieve smooth connection of the production process, provides a closer working environment for operators, shortens the moving distance between different processes, and also facilitates operators to monitor and manage the entire production process.
