[0002] The main function of the seat belt buckle is to ensure that the seat belt is properly fastened to the passenger, preventing the passenger from being injured in emergency situations such as sudden stops, collisions or turns while the vehicle is in motion. In the event of 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 number CN220881246U discloses an assembly device for a seat belt buckle, comprising a placement base, the top of the placement base is fixedly connected to two symmetrically distributed vertical plates, the tops of the two vertical plates are fixedly connected to 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 comprises a fixing box fixedly connected to the top of the placement base, a bidirectional threaded rod is rotatably connected in the fixing box, two movable plates are threadedly sleeved on the bidirectional threaded rod, one side of the two movable plates are movably extended to the outside of the fixing box, and the assembly device for the seat belt buckle can firmly fix the upper cover and the lower cover before they are extruded and assembled through the setting of the fixing mechanism, so as to prevent the upper cover and the lower cover from being offset when contacting with the pressing plate, resulting in the upper cover and the lower cover being misaligned and affecting the assembly.

[0015] The assembly method of the multi-station seat belt buckle assembly equipment based on automatic transposition includes the following steps: S1. The loading device places the lock buckle upper cover with the lock core installed on the movable mounting fixture of the upper cover switching seat, and the movable mounting fixture is used to position and fix it; at the same time, the loading device places the lock buckle lower cover on the fixed mounting fixture of the lower cover switching seat, and the fixed mounting fixture is used to position and fix it; S2, the rotation drive platform starts to work, driving the upper cover switching seat and the lower cover switching seat to rotate synchronously, and then switch positions.

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See also Figures 1 to 10 As shown, a multi-station seat belt buckle assembly device based on automatic position change 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 devices 31 for placing the buckle upper cover 1 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 device 31, and a plurality of fixed mounting devices 41 for placing the buckle lower cover 11 are installed on the lower cover switching seat 4, and the number of the fixed mounting devices 41 corresponds one to one to the number of the movable mounting devices 31.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] The movable mounting device 31 is used to position and fix the lock upper cover 1. A plurality of first suction cups 313 are embedded in the upper cover placement groove 312, which are used to firmly place the lock upper cover 1 on the movable mounting device 31 through adsorption. The movable mounting device 31 is also equipped with a telescopic rod 314, and a first reset spring 315 is connected between the telescopic rod 314 and the upper cover switching seat 3 to provide a reset mechanism.

[0029] The top of the movable mounting tool 31 is also provided with a push angle 311, which is used to dock with the synchronous expansion device 32, so that when the synchronous expansion device 32 is started, the movable mounting tool 31 is driven by physically pushing the push angle 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 the preset path when subjected to external force.

[0030] When the synchronous expansion device 32 is started and pushes the push angle 311, the movable installation device 31 is driven by 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 reserves potential energy for the return action of the movable installation device 31. Once the synchronous expansion device 32 stops resetting, the first return spring 315 releases the potential energy and drives the movable installation device 31 to return to the initial position through the cooperation of the telescopic rod 314, completing the return action.

[0031] The synergistic effect of the movable mounting device 31 and the synchronous expansion device 32 realizes the precise positioning, firm fixation and efficient movement and resetting of the lock upper cover 1, thereby supporting the continuity and efficiency of the entire assembly process.

[0032] See also 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 resistance blocks 323 are installed on the telescopic mounting frame 321, and a resistance bevel 3231 is provided on the synchronous resistance block 323.

[0033] The synchronous expansion device 32 also includes a first linear driver 324 . The telescopic end of the first linear driver 324 extends toward the telescopic mounting frame 321 . A buffering resistance block 3241 is also installed at the telescopic end of the first linear driver 324 .

[0034] The telescopic mounting frame 321 is slidably mounted on the upper cover switching seat 3, and contacts the upper cover switching seat 3 through the second reset spring 322 to provide a reset function. The synchronous contact block 323 is fixedly mounted on the telescopic mounting frame 321, and each synchronous contact block 323 is provided with a contact angle 3231 for contacting the push angle 311 on the movable mounting device 31 and generating a pushing effect.

[0035] The first linear driver 324 serves as a driving source. The telescopic end of the first linear driver 324 extends toward the telescopic mounting frame 321, and a buffering resistance block 3241 is installed at the telescopic end. When the assembly process needs to push the movable mounting device 31, the first linear driver 324 is started to push the buffering resistance block 3241, and then the driving force is transmitted to the telescopic mounting frame 321 through the buffering resistance block 3241. Under the action of 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 multiple synchronous resistance blocks 323 to move synchronously.

[0036] As the synchronous resistance block 323 moves, the resistance angle 3231 thereon contacts the push angle 311 of the movable installation device 31, and due to the design of the resistance angle 3231, the horizontal thrust is converted into a force that pushes the movable installation device 31 to move outward along the upper cover switching seat 3. After being pushed, the movable installation device 31 moves smoothly along the preset path.

[0037] When the first linear drive 324 stops working and resets, the telescopic mounting frame 321 and the synchronous abutment block 323 will be reset to the initial position under the elastic force of the second reset spring 322, and the buffer abutment block 3241 will be disconnected from the telescopic mounting frame 321. At this time, the movable mounting device 31 will also be reset to the initial position under the action of the telescopic rod 314 and the first reset spring 315, preparing for the next round of assembly process.

[0038] The synchronous expansion device 32 pushes the telescopic mounting frame 321 and the synchronous resistance block 323 to move through the telescopic action of the first linear drive 324, and then realizes the precise adjustment and promotion of the movable mounting device 31 through the interaction between the resistance angle 3231 and the push angle 311, thereby ensuring the continuity and efficiency of the assembly process.

[0039] See also Figures 4 to 8 As shown, a lower cover placement groove 411 is provided on the fixed installation device 41, and a plurality of second suction cups 412 are provided inside the lower cover placement groove 411. Retraction guide mechanisms 413 are installed on both sides of the lower cover placement groove 411, and the retraction ends of the retraction guide mechanisms 413 extend into the lower cover placement groove 411. The retraction ends of the retraction guide mechanisms 413 are used to press and lock the two sides of the lower cover 11.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The side of the limiting slide rail 52 is provided with a feed opening, which is connected to a feeder, so that the feeder can deliver the lock upper cover 1 or the lock lower cover 11 to the inside of the limiting slide rail 52. The feeder is a prior art and will not be described in detail here. A travel sensor is installed inside the limiting slide rail 52, and the travel sensor is used to detect whether the lock upper cover 1 or the lock lower cover 11 enters the specified position of the limiting slide rail 52.

[0052] The mounting frame 51 provides a stable support platform for the entire loading device 5. On the mounting frame 51, two limit slide rails 52 are installed in parallel to guide the stable movement of the lock upper cover 1 and the lock lower cover 11. The push-up base 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-up bracket 55 is installed on the mounting frame 51 and connected to the push-up base plate 53. The lifting and lowering movement of the push-up bracket 55 is achieved by the drive of the second linear drive 56. A plurality of third suction cups 54 are also provided on the push-up base plate 53 to fix the lock upper cover 1 and the lock lower cover 11 to ensure stability during the lifting process.

[0053] After the feeder delivers the lock upper cover 1 or the lock lower cover 11 to the inside of the limiting slide rail 52, the second linear drive 56 starts to work and pushes the push-up bracket 55 to move upward. The rise of the push-up bracket 55 drives the synchronous rise of the push-up bottom plate 53, and then the lock upper cover 1 and the lock lower cover 11 inside the limiting slide rail 52 are synchronously lifted. In this process, the third suction cup 54 plays a role in fixing the lock upper cover 1 and the lock lower cover 11 to prevent them from slipping or shaking. As the push-up bottom plate 53 continues to rise, the lock upper cover 1 and the lock lower cover 11 gradually approach the movable mounting device 31 and the fixed mounting device 41. When the lock upper cover 1 rises to a position in contact with the movable mounting device 31, the lock lower cover 11 also rises to a position in contact with the fixed mounting device 41. At this time, the third suction cup 54 releases the fixation of the lock upper cover 1 and the lock lower cover 11, completing the precise automatic feeding process.

[0054] The design of the entire feeding device 5 realizes the automated and precise feeding of the locking upper cover 1 and the locking lower cover 11, effectively saving labor costs and improving production efficiency.

[0055] See also Figures 2 to 4 As shown, it also includes a pressing detection device 6 installed above the upper cover switching seat 3, and the pressing detection device 6 includes two visual detection cameras 61, and the visual detection cameras 61 are used to visually detect the assembly gap between the lock upper cover 1 and the lock lower cover 11.

[0056] In the assembly process, after the lock upper cover 1 and the lock lower cover 11 are assembled by the synchronous expansion device 32, the upper cover switching seat 3 continues its rotation to transport the assembled lock components to the pressing inspection station. At this time, the two visual inspection cameras 61 are in a state to be inspected, and are positioned to capture the image of the joint area between the lock upper cover 1 and the lock lower cover 11.

[0057] The visual inspection camera 61 accurately records the gap conditions at the assembly of the lock parts. Through the image processing algorithm, the system analyzes the gap size in the captured image to determine whether the lock upper cover 1 and the lock lower cover 11 are tightly pressed together. If the detection result shows that the assembly gap exceeds the preset allowable range, it is judged as poor pressing. This information will be immediately fed back to the control system, which may trigger an alarm mechanism.

[0058] This pressing inspection process ensures the assembly quality of each pair of lock upper cover 1 and lock lower cover 11. Through the high precision and real-time performance of visual inspection technology, it effectively avoids the outflow of defective products, thereby improving the quality control level of the overall production line.

[0059] See also Figure 2 , Figure 3 and Fig.10 As shown, it includes a material unloading device 7 installed beside the upper cover switching seat 3, and the material unloading device 7 includes an adsorption plate 71 installed beside the upper cover switching seat 3. A material guiding device is installed below the adsorption plate 71, and the material guiding device is used to guide the movement of the seat belt buckle.

[0060] The adsorption plate 71 is provided with a plurality of fourth suction cups 711 for adsorbing and fixing the seat belt buckle. The material guide device comprises a rotating adjustment plate 72 rotatably mounted on the adsorption plate 71 , and further comprises a first rotary driver 73 driving the rotating adjustment plate 72 to rotate.

[0061] When the synchronous expansion device 32 drives the multiple movable fixtures 31 to move, the movable fixture 31 located in the unloading area will carry the assembled seat belt buckle and move to a position in contact with the fourth suction cup 711 on the suction plate 71. At this time, the fourth suction cup 711 will start the suction function to firmly adsorb and fix the seat belt buckle, and the movable fixture 31 will release the fixation of the seat belt buckle.

[0062] As the synchronous expansion device 32 is reset, the movable mounting device 31 is also reset and completely separated from the seat belt buckle, so that the seat belt buckle stays stably on the adsorption plate 71. Then, the fourth suction plate 711 releases its adsorption state, so that the seat belt buckle can smoothly fall onto the rotating adjustment plate 72. The rotating adjustment plate 72 is set to an inclined state, and this design can effectively guide the seat belt buckle to slide to a specified position.

[0063] In addition, the function of the first rotary driver 73 adjusting the tilt angle of the rotating adjustment plate 72 allows the sliding position of the seat belt buckle to be adjusted according to actual needs. In this way, in conjunction with the pressing detection device 6, the classification guidance of the drop position of the seat belt buckle can be achieved, thereby ensuring the accuracy and efficiency of the entire drop process.

[0064] See also Figures 2 to 4 As shown, the rotation driving platform 2 includes a planar mounting plate 21 , on which two meshing synchronous gear plates 22 are mounted. The two synchronous gear plates 22 are used to mount the upper cover switching seat 3 and the lower cover switching seat 4 .

[0065] The rotary drive platform 2 further comprises a second rotary drive 23 mounted on the planar mounting plate 21 . A driving gear 24 is mounted on the output end of the second rotary drive 23 . The driving gear 24 meshes with a synchronous gear plate 22 .

[0066] The flat mounting plate 21 is used for stable support. The two synchronous gear plates 22 installed on the flat mounting plate 21 ensure the synchronization and stability of rotation through precise meshing design. The two synchronous gear plates 22 are used to install the upper cover switching seat 3 and the lower cover switching seat 4 respectively, so as to realize the fixation and positioning of the two on the driving platform.

[0067] When the upper cover switching seat 3 and the lower cover switching seat 4 need to be driven to rotate synchronously, the second rotary driver 23 is started, and the driving gear 24 rotates accordingly. Due to the meshing relationship between the driving gear 24 and the synchronous gear plate 22, the rotation of the driving gear 24 will drive the meshing synchronous gear plate 22 to rotate synchronously. Since the two synchronous gear plates 22 are meshed with each other, when one synchronous gear plate 22 rotates, the other synchronous gear plate 22 will also rotate at the same speed and in the opposite direction.

[0068] By rotating the driving platform 2, the upper cover switching seat 3 and the lower cover switching seat 4 are synchronously rotated and adjusted. This not only ensures the synchronization and stability of the two during the rotation process, but also improves the operating efficiency and accuracy of the entire assembly equipment. At the same time, the detachable design of the synchronous gear plate 22 makes it easy to replace or maintain the upper cover switching seat 3 or the lower cover switching seat 4, further improving the flexibility and maintainability of the equipment.

[0069] The assembly method of the multi-station seat belt buckle assembly equipment based on automatic transposition includes the following steps: S1, the loading device 5 places the lock buckle upper cover 1 with the lock core installed on the movable mounting device 31 of the upper cover switching seat 3, and the movable mounting device 31 is positioned and fixed; at the same time, the loading device 5 places the lock buckle lower cover 11 on the fixed mounting device 41 of the lower cover switching seat 4, and the fixed mounting device 41 is positioned and fixed; S2, 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, and then switch positions. During the rotation process, the lock upper cover 1 and the lock lower cover 11 rotate accordingly until they are in a relatively set position; S3, when the lock upper cover 1 and the lock lower cover 11 are in relative positions, the synchronous expansion device 32 is started to push the movable mounting device 31 to move to the outer side of the upper cover switching seat 3, so that the lock upper cover 1 and the lock lower cover 11 are pressed against each other to achieve assembly; S4. At the same time, the loading device 5 places the new lock upper cover 1 and the lock lower cover 11 on the movable mounting device 31 and the fixed mounting device 41 to complete the automatic loading; S5, after the assembly is completed, the upper cover switching seat 3 continues to rotate, and the assembled lock parts are transported to the pressing inspection station. The visual inspection camera 61 captures the image of the joint area between the lock upper cover 1 and the lock lower cover 11, and analyzes the assembly gap through the image processing algorithm to judge the pressing quality. If the gap exceeds the preset threshold, the alarm mechanism is triggered; S6. After the pressing test is qualified, the movable installation device 31 located in the unloading area carries the assembled seat belt buckle and moves to contact with the adsorption plate 71. The adsorption plate 71 adsorbs and fixes the seat belt buckle. Then the movable installation device 31 is released and reset. The adsorption plate 71 releases the adsorption state, so that the seat belt buckle falls to the material guide device, and the material guide device guides the seat belt buckle to slide to the specified position. S7, after the above steps are completed, the rotation drive platform 2 is started again, driving the upper cover switching seat 3 and the lower cover switching seat 4 to rotate and switch positions, preparing for the next round of assembly, and realizing a continuous assembly process.
