Description

Technical Field

[0001] The present invention relates to the technical field of seat belt buckles, and more particularly to a multi-station seat belt buckle assembly device and an assembly method based on automatic transposition. Background Art

[0002] The main function of a seat belt buckle is to ensure that the seat belt can be correctly fixed on the passenger, preventing the passenger from being injured in case of emergencies such as sudden stops, collisions or turning during vehicle driving. During emergency braking or collision, the seat belt buckle can ensure that the seat belt provides sufficient support and protection for the occupant, preventing the passenger from flying forward due to inertia.

[0003] Chinese Patent No. CN220881246U discloses an assembly device for a seat belt buckle, including a placement base, on the top of which two symmetrically distributed vertical plates are fixedly connected, and the top of the two vertical plates is fixedly connected with the same top plate. A pressing assembly is arranged below the top plate, and a fixing mechanism is arranged on the placement base; the fixing mechanism includes a fixing box fixedly connected to the top of the placement base, a bidirectional threaded rod is rotatably connected in the fixing box, and two moving plates are threadedly sleeved on the bidirectional threaded rod. One side of each of the two moving plates extends out of the fixing box movably. For this assembly device of the seat belt buckle, the fixing mechanism can firmly fix the upper cover and the lower cover before pressing and assembling them, preventing them from shifting when contacting the pressing plate, resulting in misalignment of the upper cover and the lower cover and affecting the assembly.

[0004] Although the above device can press the upper cover and the lower cover by means of clamping and positioning to avoid misalignment, the existing assembly equipment needs to manually pre-align and place the upper cover and the lower cover before each pressing. This not only increases the labor cost, but also may cause inaccurate alignment due to human factors, affecting the assembly quality. On the other hand, after the assembly is completed, the product needs to be manually taken out of the pressing equipment and then the new upper cover and lower cover can be put in for the next assembly. This loading and unloading process is cumbersome and time-consuming, seriously affecting the assembly efficiency. Summary of the Invention

[0010] Preferably, the retraction guide mechanism includes two synchronous retraction rods slidably mounted on a fixed mounting device, and pressing and resisting blocks are distributed on the synchronous retraction rods.

[0014] Preferably, the rotation drive platform includes a planar mounting plate, on which two meshing synchronous gear discs are mounted, and the two synchronous gear discs are used to mount the upper cover switching seat and the lower cover switching seat.

[0015] An assembly method of a multi-station seat belt buckle assembly device based on automatic position change includes the following steps:

[0016] S1. The feeding device places the buckle upper cover with the lock core already installed on the movable mounting tool of the upper cover switching seat, and the movable mounting tool performs positioning and fixing; at the same time, the feeding device places the buckle lower cover on the fixed mounting tool of the lower cover switching seat, and the fixed mounting tool performs positioning and fixing;

[0017] S2. The rotation drive platform starts to work, drives the upper cover switching seat and the lower cover switching seat to rotate synchronously, and then switches positions. During the rotation, the buckle upper cover and the buckle lower cover rotate accordingly until they are in opposite positions;

[0018] S3. When the buckle upper cover and the buckle lower cover are in opposite positions, the synchronous expansion device is activated, pushing the movable mounting tool to move outward from the upper cover switching seat, so that the buckle upper cover and the buckle lower cover press against each other to achieve assembly;

If the gap exceeds the preset threshold, the alarm mechanism is triggered;

[0021] S6. After the pressing inspection is qualified, the movable mounting tool in the blanking area carries the assembled seat belt buckle to contact with the adsorption plate. The adsorption plate adsorbs and fixes the seat belt buckle. Subsequently, the movable mounting tool releases the fixation and resets, and the adsorption plate releases the adsorption state, so that the seat belt buckle falls to the guiding device, and the guiding device guides the seat belt buckle to slide to the designated position;

[0022] S7. After the above steps are completed, the rotation drive platform is started again, driving the upper cover switching seat and the lower cover switching seat to rotate and switch positions to prepare for the next round of assembly, realizing a continuous assembly process.

[0023] The beneficial effects of the present invention compared with the prior art are:

[0024] 1. The present invention automatically places the upper and lower covers of the buckle on the mounting tool of the switching base through the feeding device, and realizes the automatic transposition and alignment of the two by means of the rotating drive table, without the need for manual pre-alignment and placement, avoiding the problem of inaccurate alignment caused by human factors. At the same time, the automatic feeding and discharging mechanism also reduces the manual participation. Through multi-station collaborative assembly, the assembly efficiency is significantly improved and the labor cost is reduced.

[0025] 2. During the assembly process of the present invention, the synchronous expansion device is used to push the movable mounting tool to move precisely, ensuring the precise pressing and assembly between the upper and lower covers of the buckle, effectively avoiding the dislocation phenomenon. In addition, the pressing detection station uses a vision detection camera to capture the image of the bonding area, and analyzes the assembly gap through an image processing algorithm to realize the precise judgment of the pressing quality, further improving the assembly accuracy and overall quality of the product.

[0026] 3. After the assembly is completed, the present invention can automatically transport the assembled buckle components to the pressing detection station for detection, and after passing the inspection, realize rapid discharging through the coordinated action of the adsorption plate and the feeding device. At the same time, the rotating drive table can quickly switch positions to prepare for the next round of assembly. The entire assembly process is compact and orderly, avoiding the cumbersome feeding and discharging process, significantly improving the production efficiency, and realizing a continuous and efficient production mode.

Detailed implementation manners

[0038] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific implementation manners.

[0039] Refer to Figures 1 to 10 As shown, the multi-station seat belt buckle assembly device based on automatic transposition includes a rotating drive table 2 installed on a frame. An upper cover switching seat 3 and a lower cover switching seat 4 are installed on the rotating drive table 2. The upper cover switching seat 3 and the lower cover switching seat 4 are arranged adjacent to each other. A plurality of movable mounting tools 31 for placing the upper covers 1 of the buckles are installed on the upper cover switching seat 3. A synchronous expansion device 32 is also installed on the upper cover switching seat 3. The synchronous expansion device 32 is used to adjust the movement of the movable mounting tools 31. A plurality of fixed mounting tools 41 for placing the lower covers 11 of the buckles are installed on the lower cover switching seat 4. The number of the fixed mounting tools 41 corresponds one-to-one to the number of the movable mounting tools 31.

[0040] During the assembly process, first, the staff places the lock buckle upper cover 1 with the lock core installed on the movable mounting tool 31, and the movable mounting tool 31 positions and fixes the lock buckle upper cover 1. At the same time, the lock buckle lower cover 11 is placed on the fixed mounting tool 41, and the fixed mounting tool 41 positions and fixes the lock buckle lower cover 11.

[0041] When the upper lock cover 1 and the lower lock cover 11 are properly placed, the rotation drive platform 2 starts to work, driving the upper cover switching seat 3 and the lower cover switching seat 4 to rotate synchronously, thereby switching positions. During the rotation process, the upper lock cover 1 and the lower lock cover 11 also rotate accordingly until the upper lock cover 1 and the lower lock cover 11 are in a relatively set position.

[0042] At this time, the synchronous expansion device 32 is activated to push the movable mounting device 31 to move toward the outside of the upper cover switching seat 3. As the movable mounting device 31 moves, the lock upper cover 1 and the lock lower cover 11 will press against each other to achieve assembly. During this process, the staff can simultaneously place the new lock upper cover 1 and the lock lower cover 11 on the corresponding movable mounting device 31 and the fixed mounting device 41 to prepare for the next round of assembly.

[0043] When the lock upper cover 1 and the lock lower cover 11 are assembled, the synchronous expansion device 32 drives the movable mounting device 31 to reset synchronously. When the movable mounting device 31 is reset, the fixed mounting device 41 will release the fixing of the lock lower cover 11, so that the lock lower cover 11 and the lock upper cover 1 are separated from the fixed mounting device 41.

[0044] Subsequently, the rotating driving platform 2 is started again, driving the upper cover switching seat 3 and the lower cover switching seat 4 to rotate and switch positions. In this process, the newly unassembled lock buckle upper cover 1 and the lock buckle lower cover 11 are moved to relative positions, and the upper cover switching seat 3 moves the assembled lock buckle upper cover 1 and the lock buckle lower cover 11 to the position to be unloaded, thereby realizing unloading.

[0045] Through the above working principle, the equipment realizes a continuous assembly process, greatly reduces the time for loading and unloading, ensures the continuity of assembly, and significantly improves production efficiency.

[0046] See also Figures 2 to 6 As shown, the movable mounting device 31 is provided with an upper cover placement groove 312 inside, and a plurality of first suction cups 313 are provided inside the upper cover placement groove 312. A telescopic rod 314 is also installed on the movable mounting device 31, and a first return spring 315 is installed between the telescopic rod 314 and the upper cover switching seat 3.

[0047] The movable mounting tool 31 is used to position and fix the upper cover of the buckle 1. A plurality of first suction cups 313 are embedded in the upper cover placement groove 312 for stably placing the upper cover of the buckle 1 on the movable mounting tool 31 through adsorption. The movable mounting tool 31 is also equipped with a telescopic rod 314, and a first return spring 315 is connected between the telescopic rod 314 and the upper cover switching seat 3 to provide a reset mechanism.

[0048] A pushing bevel 311 is also provided at the top of the movable mounting tool 31. The pushing bevel 311 is used to dock with the synchronous expansion device 32, so that when the synchronous expansion device 32 is activated, the movable mounting tool 31 is driven by physically pushing the pushing bevel 311. The movable mounting tool 31 and the upper cover switching seat 3 are connected in a sliding manner to ensure that the movable mounting tool 31 can move smoothly along a preset path when subjected to an external force.

[0049] When the synchronous expansion device 32 is activated and pushes the pushing bevel 311, the movable mounting tool 31 is driven by the external force and moves outward along the upper cover switching seat 3. During this movement, the telescopic rod 314 moves accordingly and compresses the first return spring 315. The compressed state of the first return spring 315 stores potential energy for the reset action of the movable mounting tool 31. Once the synchronous expansion device 32 resets and stops acting, the first return spring 315 releases the potential energy and drives the movable mounting tool 31 back to the initial position through the cooperation of the telescopic rod 314 to complete the reset action.

[0050] The coordinated action of the movable mounting tool 31 and the synchronous expansion device 32 realizes the precise positioning, stable fixation and efficient movement and reset of the upper cover of the buckle 1, thus supporting the continuity and efficiency of the entire assembly process.

[0051] See Figures 2 to 6 As shown, the synchronous expansion device 32 includes a telescopic mounting frame 321 slidably mounted on the upper cover switching seat 3. A second return spring 322 is installed between the telescopic mounting frame 321 and the upper cover switching seat 3. A plurality of synchronous abutting blocks 323 are installed on the telescopic mounting frame 321, and abutting bevels 3231 are provided on the synchronous abutting blocks 323.

[0052] The synchronous expansion device 32 further includes a driving first linear driver 324. The telescopic end of the first linear driver 324 extends towards the telescopic mounting frame 321, and a buffer abutting block 3241 is also installed at the telescopic end of the first linear driver 324.

[0053] The telescopic mounting frame 321 is slidably mounted on the upper cover switching seat 3 and abuts against the upper cover switching seat 3 through the second return spring 322 to provide a reset function. The synchronous abutting blocks 323 are fixedly installed on the telescopic mounting frame 321, and abutting bevels 3231 are provided on each synchronous abutting block 323 for contacting and generating a pushing action with the pushing bevel 311 on the movable mounting tool 31.

[0054] The first linear driver 324 serves as a driving source. The telescopic end of the first linear driver 324 extends towards the telescopic mounting frame 321, and a buffer abutting block 3241 is installed at the telescopic end. When the assembly process requires pushing the movable mounting tool 31, the first linear driver 324 is activated to push the buffer abutting block 3241, and then the driving force is transmitted to the telescopic mounting frame 321 through the buffer abutting block 3241. Under the action of the pressure, the telescopic mounting frame 321 will overcome the elastic force of the second return spring 322, slide along the upper cover switching seat 3, and drive the plurality of synchronous abutting blocks 323 to move synchronously.

[0055] As the synchronous abutting block 323 moves, the abutting bevel 3231 thereon will contact the pushing bevel 311 of the movable mounting tool 31. Due to the design of the abutting bevel 3231, the horizontal thrust is converted into a force that pushes the movable mounting tool 31 to move outward along the upper cover switching seat 3. After being pushed, the movable mounting tool 31 will move smoothly along the preset path.

[0056] When the first linear driver 324 stops working and resets, the telescopic mounting frame 321 and the synchronous abutting block 323 will reset to the initial position under the elastic force of the second return spring 322. At the same time, the buffer abutting block 3241 is disengaged from the telescopic mounting frame 321. At this time, the movable mounting tool 31 will also reset to the initial position under the action of the telescopic rod 314 and the first return spring 315, preparing for the next round of assembly process.

[0057] The synchronous expansion device 32 drives the telescopic mounting frame 321 and the synchronous abutting block 323 to move through the telescopic action of the first linear driver 324, and then realizes the precise adjustment and pushing of the movable mounting tool 31 through the interaction between the abutting bevel 3231 and the pushing bevel 311, ensuring the continuity and efficiency of the assembly process.

[0058] See Figures 4 to 8 As shown, the fixed mounting tool 41 is provided with a lower cover placement groove 411. A plurality of second suction cups 412 are arranged inside the lower cover placement groove 411. Shrinkage guiding mechanisms 413 are installed on both sides of the lower cover placement groove 411. The shrinkage ends of the shrinkage guiding mechanisms 413 extend towards the inside of the lower cover placement groove 411, and the shrinkage ends of the shrinkage guiding mechanisms 413 are used to press both sides of the locking lower cover 11.

[0059] The fixing fixture 41 is used to ensure the stability and accuracy of the lock lower cover 11 during the assembly process. The size of the lower cover placement groove 411 matches the shape of the lock lower cover 11 to achieve preliminary limit fixation. A plurality of second suction cups 412 are arranged inside the lower cover placement groove 411. The second suction cups 412 further firmly hold the lock lower cover 11 in the lower cover placement groove 411 by generating a negative pressure adsorption force to prevent displacement during the assembly process. In addition, a retraction guide mechanism 413 is installed on both sides of the lower cover placement groove 411. The retraction end of the retraction guide mechanism 413 extends to the inside of the lower cover placement groove 411, and can press on both sides of the lock lower cover 11.

[0060] When the lock lower cover 11 is correctly placed in the lower cover placement groove 411 and fixed by the suction disc, with the rotation of the rotating drive platform 2 and the start-up of the synchronous expansion device 32, the movable mounting device 31 drives the lock upper cover 1 to move toward the lock lower cover 11. In this process, the movement of the movable mounting device 31 will trigger the contraction guide mechanism 413, so that its contraction end starts to work and appropriately squeezes the two sides of the lock lower cover 11. This action of the contraction guide mechanism 413 causes the two sides of the lock lower cover 11 to contract and deflect inward, thereby adjusting the shape of the lock lower cover 11, making it easier to accurately assemble with the lock upper cover 1. This design not only improves the assembly accuracy, but also helps to reduce the assembly difficulties caused by slight differences between the upper and lower covers of the lock. The fixed mounting device 41 achieves effective fixation and shape adjustment of the lock lower cover 11 through the synergistic effect of the lower cover placement groove 411, the second suction disc 412 and the contraction guide mechanism 413, providing a solid foundation for the smooth assembly of the upper and lower covers of the lock.

[0061] See also Figure 4 and Figure 8 As shown, the retraction guide mechanism 413 includes two synchronous retraction rods 414 slidably mounted on the fixed mounting device 41, and pressing and resisting blocks 415 are distributed on the synchronous retraction rods 414. Both ends of the synchronous retraction rods 414 are equipped with pressing and retraction mechanisms, which are used to drive the synchronous retraction rods 414 to perform retraction movement.

[0062] The shrinkage guide mechanism 413 is used to accurately adjust the shape of the lock lower cover 11 to ensure that the lock upper and lower covers can be assembled smoothly.

[0063] The retraction guide mechanism 413 is mainly composed of two synchronous retraction rods 414, which are slidably mounted on the fixed mounting device 41 and can move along a preset track. The synchronous retraction rods 414 are evenly distributed with pressing and resisting blocks 415, which are used to press the two sides of the lock lower cover 11 during the retraction process.

[0064] The two ends of the synchronous contraction rod 414 are respectively installed with a pressing contraction mechanism, which drives the synchronous contraction rod 414 to perform a contraction movement. The pressing contraction mechanism includes a telescopic resistance rod 416 slidably installed on the fixed installation device 41, and the telescopic resistance rod 416 can move under the action of an external force. A connecting rod 417 is rotatably installed on the telescopic resistance rod 416, and the other end of the connecting rod 417 is rotatably connected to the synchronous contraction rod 414, so that the movement of the telescopic resistance rod 416 can be converted into the contraction movement of the synchronous contraction rod 414. In order to provide a stable reset force, a third reset spring 418 is installed between the telescopic resistance rod 416 and the fixed installation device 41. When the telescopic resistance rod 416 is moved by an external force, the third reset spring 418 will be compressed to store elastic potential energy. When the external force disappears, the third reset spring 418 will release the stored elastic potential energy and push the telescopic resistance rod 416 to reset.

[0065] During the assembly process, when the movable mounting fixture 31 moves toward the fixed mounting fixture 41, it will first collide with the telescopic interference rod 416. This interference causes the telescopic interference rod 416 to move, thereby squeezing the third return spring 418 and driving the connecting rod 417 to move synchronously. The contraction movement of the connecting rod 417 is transmitted to the synchronous contraction rod 414, causing the synchronous contraction rod 414 to move along the fixed mounting fixture 41.

[0066] As the synchronous retracting rod 414 moves, the pressing and resisting block 415 contacts and applies pressure to both sides of the lock lower cover 11, causing both sides of the lock lower cover 11 to shrink and deflect inward. This adjustment makes the shape of the lock lower cover 11 more consistent with the requirements of the lock upper cover 1, thereby improving the accuracy and efficiency of assembly.

[0067] The retracting guide mechanism 413 realizes the precise adjustment of the shape of the lock buckle lower cover 11. It not only improves the assembly accuracy and efficiency, but also helps to reduce the assembly difficulties caused by the slight difference between the upper and lower covers of the lock buckle.

[0068] See also Figures 2 to 9 As shown, it includes a loading device 5 installed below the rotating driving platform 2, and the loading device 5 includes a mounting frame 51 installed at the bottom of the rotating driving platform 2, two limiting slide rails 52 are installed on the mounting frame 51, and a push-up mechanism is installed at the bottom of the limiting slide rail 52.

[0069] The pushing mechanism includes a pushing base plate 53 distributed at the bottom of each limiting slide rail 52, the pushing base plate 53 is slidably connected to the limiting slide rail 52, the pushing mechanism includes a pushing bracket 55 installed on the mounting frame 51, the pushing bracket 55 is connected to the pushing base plate 53, and a plurality of third suction cups 54 are provided on the pushing base plate 53, and the pushing mechanism also includes a second linear drive 56 for driving the pushing bracket 55 to move up and down.

[0070] A feed opening is provided on the side of the limit slide rail 52. The feed opening is connected to the feeder, facilitating the feeder to convey the upper lock cover 1 or the lower lock cover 11 into the interior of the limit slide rail 52. The feeder is a prior art and will not be elaborated here. A travel sensor is installed inside the limit slide rail 52, and the travel sensor is used to detect whether the upper lock cover 1 or the lower lock cover 11 enters the designated position of the limit slide rail 52.

[0071] The mounting frame 51 provides a stable support platform for the entire feeding device 5. On the mounting frame 51, two limit slide rails 52 are installed in parallel to guide the stable movement of the upper lock cover 1 and the lower lock cover 11. The push top bottom plate 53 is slidably connected to the limit slide rail 52 and can move along the track of the limit slide rail 52. The push top bracket 55 is installed on the mounting frame 51 and is connected to the push top bottom plate 53. Through the drive of the second linear actuator 56, the lifting movement of the push top bracket 55 is realized. On the push top bottom plate 53, a plurality of third suction cups 54 are further provided to fix the upper lock cover 1 and the lower lock cover 11 to ensure stability during the ascending process.

[0072] After the feeder conveys the upper lock cover 1 or the lower lock cover 11 into the interior of the limit slide rail 52, the second linear actuator 56 starts to work, pushing the push top bracket 55 to move upward. The upward movement of the push top bracket 55 drives the synchronous upward movement of the push top bottom plate 53, thereby synchronously lifting the upper lock cover 1 and the lower lock cover 11 inside the limit slide rail 52. During this process, the third suction cups 54 play a role in fixing the upper lock cover 1 and the lower lock cover 11 to prevent them from slipping or shaking. As the push top bottom plate 53 continues to rise, the upper lock cover 1 and the lower lock cover 11 also gradually approach the movable mounting tool 31 and the fixed mounting tool 41. When the upper lock cover 1 rises to the position where it contacts the movable mounting tool 31, the lower lock cover 11 also exactly rises to the position where it contacts the fixed mounting tool 41. At this time, the third suction cups 54 release the fixation of the upper lock cover 1 and the lower lock cover 11, completing the precise automatic feeding process.

[0073] The design of the entire feeding device 5 realizes the automatic and precise feeding of the upper lock cover 1 and the lower lock cover 11, effectively saving labor costs and improving production efficiency.

[0074] See Figures 2 to 4 As shown, it further includes a pressing detection device 6 installed above the upper cover switching seat 3. The pressing detection device 6 includes two visual detection cameras 61, and the visual detection cameras 61 are used for visual detection of the assembly gap between the upper lock cover 1 and the lower lock cover 11.

[0075] In the assembly process, after the upper cover 1 of the buckle and the lower cover 11 of the buckle are assembled by the pushing of the synchronous expansion device 32, the upper cover switching seat 3 continues its rotation action to transport the assembled buckle components to the pressing and detection station. At this time, the two vision detection cameras 61 are in a waiting state for detection, positioned to capture images of the combined area of the upper cover 1 of the buckle and the lower cover 11 of the buckle.

[0076] The vision detection cameras 61 accurately record the gap condition at the assembly location of the buckle components. Through image processing algorithms, the system analyzes the gap size in the captured images to determine whether the upper cover 1 of the buckle and the lower cover 11 of the buckle are tightly pressed together. If the detection result shows that the assembly gap exceeds the preset allowable range, it is determined that the pressing is defective, and this information will be immediately fed back to the control system, which may trigger an alarm mechanism.

[0077] This pressing and detection process ensures the assembly quality of each pair of the upper cover 1 of the buckle and the lower cover 11 of the buckle. Through the high precision and real-time nature of vision detection technology, it effectively avoids the outflow of defective products, thus improving the quality control level of the overall production line.

[0078] See Figure 2 、 Figure 3 and Figure 10 As shown, it includes a blanking device 7 installed beside the upper cover switching seat 3. The blanking device 7 includes an adsorption plate 71 installed beside the upper cover switching seat 3, and a material guiding device is installed below the adsorption plate 71. The material guiding device is used to guide the movement of the seat belt buckle.

[0079] A plurality of fourth suction cups 711 are provided on the adsorption plate 71, and the fourth suction cups 711 are used to adsorb and fix the seat belt buckle. The material guiding device includes a rotating adjustment plate 72 rotatably installed on the adsorption plate 71, and the material guiding device further includes a first rotation driver 73 for driving the rotating adjustment plate 72 to rotate.

[0080] During the process of the synchronous expansion device 32 driving a plurality of movable mounting tools 31 to move, the movable mounting tool 31 located in the blanking area will carry the assembled seat belt buckle to a position where it contacts the fourth suction cups 711 on the adsorption plate 71. At this time, the fourth suction cups 711 will activate the adsorption function to firmly adsorb and fix the seat belt buckle, and at the same time, the movable mounting tool 31 will release the fixation of the seat belt buckle.

[0081] With the reset of the synchronous expansion device 32, the movable mounting tool 31 will also reset and completely separate from the seat belt buckle, so that the seat belt buckle stays stably on the adsorption plate 71. Subsequently, the fourth suction cups 711 will release their adsorption state, enabling the seat belt buckle to smoothly fall onto the rotating adjustment plate 72. The rotating adjustment plate 72 is set to be in an inclined state, and this design can effectively guide the seat belt buckle to slide to the designated position.

[0082] In addition, the first rotation driver 73 adjusts the tilt angle of the rotation adjustment plate 72, enabling the sliding position of the seat belt buckle to be adjusted according to actual requirements. In this way, in cooperation with the pressing detection device 6, classification guidance for the blanking position of the seat belt buckle can be achieved, ensuring the accuracy and efficiency of the entire blanking process.

[0083] See Figures 2 to 4 As shown, the rotation drive table 2 includes a flat mounting plate 21, on which two meshing synchronous gear discs 22 are mounted. The two synchronous gear discs 22 are used to mount the upper cover switching seat 3 and the lower cover switching seat 4.

[0084] The rotation drive table 2 further includes a second rotation driver 23 mounted on the flat mounting plate 21. A drive gear 24 is mounted at the output end of the second rotation driver 23, and the drive gear 24 meshes with one of the synchronous gear discs 22.

[0085] The flat mounting plate 21 is used for stable support. The two synchronous gear discs 22 mounted on the flat mounting plate 21 ensure the synchronism and stability of rotation through precise meshing design. These two synchronous gear discs 22 are respectively used to mount the upper cover switching seat 3 and the lower cover switching seat 4, realizing the fixation and positioning of both on the drive table.

[0086] When it is necessary to drive the upper cover switching seat 3 and the lower cover switching seat 4 to rotate synchronously, the second rotation driver 23 is started, and the drive gear 24 rotates accordingly. Due to the meshing relationship between the drive gear 24 and the synchronous gear disc 22, the rotation of the drive gear 24 drives the meshing synchronous gear disc 22 to rotate synchronously. Since the two synchronous gear discs 22 are meshed with each other, when one synchronous gear disc 22 rotates, the other synchronous gear disc 22 will also rotate at the same speed and in the opposite direction.

[0087] Through the rotation drive table 2, synchronous rotation adjustment of the upper cover switching seat 3 and the lower cover switching seat 4 is achieved. It not only ensures the synchronism and stability of both during rotation, but also improves the operation efficiency and accuracy of the entire assembly equipment. At the same time, the detachable design of the synchronous gear disc 22 enables the upper cover switching seat 3 or the lower cover switching seat 4 to be conveniently replaced or maintained, further enhancing the flexibility and maintainability of the equipment.

[0088] The assembly method of the multi-station seat belt buckle assembly equipment based on automatic transposition includes the following steps:

[0089] S1. The feeding device 5 places the buckle upper cover 1 with the lock core already installed on the movable mounting tool 31 of the upper cover switching seat 3, and the movable mounting tool 31 performs positioning and fixation; at the same time, the feeding device 5 places the buckle lower cover 11 on the fixed mounting tool 41 of the lower cover switching seat 4, and the fixed mounting tool 41 performs positioning and fixation;

[0090] S2. The rotation drive table 2 starts to work, driving the upper cover switching seat 3 and the lower cover switching seat 4 to rotate synchronously, and then switching positions. During the rotation, the upper cover lock 1 and the lower cover lock 11 rotate accordingly until they are in the relatively set positions.

[0091] S3. When the upper cover lock 1 and the lower cover lock 11 are in the relative positions, the synchronous expansion device 32 is activated, pushing the movable mounting tool 31 to move outward of the upper cover switching seat 3, so that the upper cover lock 1 and the lower cover lock 11 press against each other to achieve assembly.

[0092] S4. At the same time, the feeding device 5 places the new upper cover lock 1 and the lower cover lock 11 onto the movable mounting tool 31 and the fixed mounting tool 41 to complete automatic feeding.

[0093] S5. After the assembly is completed, the upper cover switching seat 3 continues to rotate, transporting the assembled lock components to the pressing and inspection station. The visual inspection camera 61 captures the image of the combined area of the upper cover lock 1 and the lower cover lock 11, analyzes the assembly gap through the image processing algorithm, and judges the pressing quality. If the gap exceeds the preset threshold, the alarm mechanism is triggered.

[0094] S6. After the pressing inspection is qualified, the movable mounting tool 31 located in the blanking area moves the assembled seat belt lock into contact with the adsorption plate 71. The adsorption plate 71 adsorbs and fixes the seat belt lock. Subsequently, the movable mounting tool 31 releases the fixation and resets, and the adsorption plate 71 releases the adsorption state, causing the seat belt lock to fall to the guiding device. The guiding device guides the seat belt lock to slide to the designated position.

[0095] S7. After the above steps are completed, the rotation drive table 2 is started again, driving the upper cover switching seat 3 and the lower cover switching seat 4 to rotate and switch positions to prepare for the next round of assembly, realizing a continuous assembly process.

[0096] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
