Description

Technical Field

[0001] This application relates to the field of automotive seat processing technology, specifically a welding device for automotive seat parts. Background Technology

[0002] Automotive seat component welding equipment is a specialized automated or semi-automated device designed specifically for automotive seat production. Its core function is to permanently connect metal or polymer components of the seat through specific welding processes, ensuring that the welded components meet the stringent standards of the automotive industry for structural strength, precision, durability, and safety.

[0003] Patent No. CN202322840371.8 discloses a welding fixture for the toothed housing of an automotive seat adjuster, belonging to the field of automotive seat welding. This invention uses a fixture assembly to clamp the workpiece at one time. After welding one side of the workpiece, the motor drives the rotating platform to rotate 180° to continue welding the other side of the workpiece. This avoids the waste of time caused by manual reversal and secondary clamping of the workpiece, and ensures the consistency of the welded products and improves the stability of the products.

[0004] However, the aforementioned and existing welding devices cannot integrate product clamping and product flipping welding actions, resulting in the need to add additional electrical components.

[0005] Therefore, it is necessary to provide a welding device for automotive seat parts to solve the problem that the product clamping and product flipping welding actions cannot be integrated, which leads to the need to add additional electrical components.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a welding device for automotive seat parts, which can integrate product clamping and product flipping welding actions, thereby reducing the use of electrical components.

[0008] The technical solution adopted by this application to solve its technical problem is: a welding device for automotive seat parts, including a welding robot, a first platform located on one side in front of the welding robot, and a second platform located on the other side in front of the welding robot. The first platform is equipped with a transmission assembly for clamping the welded product, and the transmission assembly includes a rotary motor installed inside the first platform.

[0009] Gear fixedly connected to the output end of a rotary motor;

[0010] A first flip plate is located on one side of the first platform. A rack that meshes with the gear is slidably connected to one side of the first flip plate. There are two sets of racks, and the two sets of racks are symmetrical about the center of the gear.

[0011] A third sliding groove is formed inside the first flip plate. There are two sets of the third sliding grooves. Each set of the third sliding grooves is slidably connected to a matching third slider. One side of the third slider is fixedly connected to one side of the rack, and the other side of the third slider is fixedly connected to a movable plate.

[0012] Furthermore, a synchronous shaft is fixedly connected to one side of the second platform, a fourth sliding groove is provided on one side of the second platform, and an arc-shaped groove is provided on one side of the second platform that communicates with one end of the fourth sliding groove. There are two sets of both the fourth sliding groove and the arc-shaped groove, and the groove opening width is the same.

[0013] Furthermore, a second flip plate is rotatably connected to one side of the synchronous shaft. The interior of the second flip plate is provided with a second sliding groove. There are two sets of the second sliding grooves. The size and position of the two sets of the second sliding grooves correspond to the two sets of the fourth sliding grooves. The interior of the two sets of the fourth sliding grooves is slidably connected with matching cylindrical sliders. Both sets of the cylindrical sliders pass through the two sets of the second sliding grooves. A clamping plate is provided between the first flip plate and the second flip plate. There are two sets of the clamping plates.

[0014] Furthermore, the two sets of fourth sliding grooves are internally slidably connected with matching cylindrical sliders. Both sets of cylindrical sliders pass through the two sets of second sliding grooves, and the other side of the two sets of cylindrical sliders is respectively fixedly connected to one side of the two sets of moving plates.

[0015] Furthermore, both the first and second flip plates have a first sliding groove inside. There are two sets of the first sliding grooves. A matching first slider is slidably connected inside the first sliding groove. Both sides of the two sets of clamping plates are fixedly connected to one side of the first slider.

[0016] Furthermore, a spring is installed on one side of the clamping plate, and the other end of the spring is connected to the moving plate.

[0017] Furthermore, a first bevel gear is fixedly connected to the outside of the synchronous shaft, and a movable groove is provided inside the second flip plate. A second bevel gear that meshes with the first bevel gear is rotatably connected inside the movable groove via a rotating shaft.

[0018] Furthermore, a first limiting plate is rotatably connected to the top of the second tilting plate, a first roller is fixedly connected to one side of the first limiting plate, a second limiting plate is rotatably connected to the bottom of the second tilting plate, a second roller is fixedly connected to one side of the second limiting plate, a third roller is fixedly connected to one side of the second bevel gear, and a track is wound around the outer side of the first roller, the second roller and the third roller.

[0019] The beneficial effects of this application are as follows: When welding is required, the product is placed on the second limiting plate, and then the rotary motor is started. The rotation of the gears causes the two sets of racks to move towards each other, which in turn drives the two sets of moving plates to move towards each other. The cylindrical sliders at the other end of the two sets of moving plates are limited in the fourth sliding groove in the horizontal direction. Therefore, the two sets of racks can move towards each other stably, thereby clamping the product with the clamping plate. Then, welding can be performed on the front side of the product. After the front side welding is completed, the rotary motor is continuously started to rotate, and the two sets of moving plates will continue to move towards each other. Since the product is in a clamped state, that is, the clamping plate is in a fixed state, the spring will continue to contract. When the cylindrical slider moves to the arc groove, the rotation of the rotary motor will cause the cylindrical slider to move to the end of the arc groove, and the clamping distance does not change, thus realizing the flipping of the product. The device can weld the reverse side of the product. This design uses only one electrical component to realize the integration of product clamping and product flipping welding, reducing the use of electrical components.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figure 1 , 2 As shown in Figures 3 and 6, this application provides a welding apparatus for automotive seat components, including a welding robot 1, a first platform 2 located on one side in front of the welding robot 1, and a second platform 3 located on the other side in front of the welding robot 1. The first platform 2 is equipped with a transmission assembly for clamping the welded product, and the transmission assembly includes a rotary motor 4 installed inside the first platform 2.

[0034] Gear 12 is fixedly connected to the output end of the rotary motor 4;

[0035] The first flip plate 8 is located on one side of the first platform 2. A rack 13 that meshes with the gear 12 is slidably connected to one side of the first flip plate 8. There are two sets of racks 13, and the two sets of racks 13 are symmetrical about the center of the gear 12.

[0036] The third sliding groove 20 is opened inside the first flip plate 8. There are two sets of the third sliding groove 20. The interior of each set of the third sliding groove 20 is slidably connected with a matching third slider 27. One side of the third slider 27 is fixedly connected to one side of the rack 13, and the other side of the third slider 27 is fixedly connected to the movable plate 6.

[0037] Both the first flip plate 8 and the second flip plate 9 have a first sliding groove 14 inside. There are two sets of first sliding grooves 14. The first sliding groove 14 is slidably connected to a matching first slider 16. Both sides of the two sets of clamping plates 5 are fixedly connected to one side of the first slider 16.

[0038] A spring 7 is installed on one side of the clamping plate 5, and the other end of the spring 7 is connected to the moving plate 6.

[0039] In this embodiment, when welding is required on the product, the product is placed on the rack, and the rotary motor 4 is started. The rotation of the gear 12 causes the two sets of racks 13 to move towards each other, which in turn drives the two sets of moving plates 6 to move towards each other. When the two sets of moving plates 6 move towards each other, they compress the spring 7, causing the spring 7 to push the clamping plate 5 to move. At the same time as the clamping plate 5 moves, the first slider 16 moves in the first sliding groove 14. When the two sets of clamping plates 5 contact the product, the rotary motor 4 is continuously started, so that the spring 7 is in a compressed and taut state, thus completing the clamping of the product. The device can then control the welding robot 1 to weld the product through the PLC. This welding robot 1 can refer to the utility model with patent number CN222243279U.

[0040] like Figure 3 , 4 As shown in Figure 5, a synchronous shaft 24 is fixedly connected to one side of the second platform 3. A fourth sliding groove 26 is provided on one side of the second platform 3. An arc-shaped groove 25 connected to one end of the fourth sliding groove 26 is provided on one side of the second platform 3. There are two sets of the fourth sliding groove 26 and the arc-shaped groove 25, and the groove opening width is the same.

[0041] A second flip plate 9 is rotatably connected to one side of the synchronous shaft 24. The interior of the second flip plate 9 is provided with a second sliding groove 15. There are two sets of second sliding grooves 15. The size and position of the two sets of second sliding grooves 15 correspond to the two sets of fourth sliding grooves 26. The interior of the two sets of fourth sliding grooves 26 is slidably connected with matching cylindrical sliders 19. Both sets of cylindrical sliders 19 pass through the two sets of second sliding grooves 15. A clamping plate 5 is provided between the first flip plate 8 and the second flip plate 9. There are two sets of clamping plates 5.

[0042] The two sets of fourth sliding grooves 26 are internally connected to cylindrical sliders 19 that match them. Both sets of cylindrical sliders 19 pass through the two sets of second sliding grooves 15. The other side of the two sets of cylindrical sliders 19 is fixedly connected to one side of the two sets of moving plates 6 respectively.

[0043] In this embodiment, after the clamping plate 5 clamps the product, the product is in a fixed state, and both sets of clamping plates 5 are in a fixed state. When the front of the product is welded and it is necessary to flip the product, the rotary motor 4 is continuously started, the two sets of moving plates 6 move towards each other continuously, the spring 7 continuously contracts, and during this process, the cylindrical slider 19 at the other end of the two sets of moving plates 6 moves from the horizontal fourth sliding groove 26 to one end of the arc groove 25. The continuous rotation of the rotary motor 4 causes the cylindrical slider 19 to start moving in the arc groove 25, and during this process, the synchronous shaft 24 starts to rotate, the distance between the two sets of moving plates 6 no longer changes, and the second flipping plate 9 is flipped, and the first flipping plate 8 is flipped in conjunction. When the cylindrical slider 19 moves to the end of the arc groove 25, the product can be flipped 180°, and then the welding robot 1 can weld the back of the product.

[0044] like Figure 3 , 4 As shown in Figure 5, a first bevel gear 17 is fixedly connected to the outside of the synchronous shaft 24, and a movable groove is provided inside the second flip plate 9. A second bevel gear 18 that meshes with the first bevel gear 17 is rotatably connected inside the movable groove through a rotating shaft.

[0045] The top of the second flip plate 9 is rotatably connected to the first limiting plate 10, and the first roller 21 is fixedly connected to one side of the first limiting plate 10. The bottom of the second flip plate 9 is rotatably connected to the second limiting plate 11, and the second roller 22 is fixedly connected to one side of the second limiting plate 11. The third roller is fixedly connected to one side of the second bevel gear 18. The outer sides of the first roller 21, the second roller 22 and the third roller are wrapped with a track 23.

[0046] In this embodiment, when the second limiting plate 11 starts to rotate, the second bevel gear 18 will mesh with the first bevel gear 17 and rotate. When the second bevel gear 18 rotates, it will drive the third roller, which in turn will drive the track 23 to rotate, thereby rotating the first roller 21 and the second roller 22 around which the track 23 is wound. This causes the first limiting plate 10 and the second limiting plate 11 to rotate. When the cylindrical slider 19 is at the beginning of the arc groove 25, the first limiting plate 10 is in a vertical state and the second limiting plate 11 is in a horizontal state. When the cylindrical slider 19 is at the end of the arc groove 25, the first limiting plate 10 is in a horizontal state and the second limiting plate 11 is in a vertical state. This means that the first limiting plate 10 and the second limiting plate 11 can support the product when welding on the front or back.

[0047] Working principle: When welding is required, the product is placed on the second limiting plate 11, and then the rotary motor 4 is started. The rotation of the gear 12 causes the two sets of racks 13 to move towards each other, which in turn drives the two sets of moving plates 6 to move towards each other. The cylindrical sliders 19 at the other end of the two sets of moving plates 6 are limited in the fourth sliding groove 26 in the horizontal direction. Therefore, the two sets of racks 13 can move towards each other stably, thereby clamping the product with the clamping plate 5. Then, welding can be performed on the front side of the product. After the front side welding is completed, the rotary motor 4 is continuously started to rotate, and the two sets of moving plates 6 will continue to move towards each other. Since the product is in a clamped state, that is, the clamping plate 5 is in a fixed state, the spring 7 will continue to contract. When the cylindrical slider 19 moves to the arc groove, the rotary motor 7 will release the pressure of the arc groove. The rotation of machine 4 will cause the cylindrical slider 19 to move to the end of the arc groove 25 without changing the clamping distance, thus realizing the flipping of the product. The device can weld the reverse side of the product. This design uses only one electrical component to realize the integration of product clamping and product flipping welding. When the second limiting plate 11 starts to rotate, the second bevel gear 18 will mesh with the first bevel gear 17 and rotate. When the second bevel gear 18 rotates, it will drive the third roller, which will then drive the track 23 to rotate. This will in turn rotate the first roller 21 and the second roller 22 around the track 23, causing the first limiting plate 10 and the second limiting plate 11 to rotate. Thus, the first limiting plate 10 and the second limiting plate 11 can support the product when welding the front or back side of the product.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
