Description

Technical Field

[0001] This utility model relates to the field of automotive seat frame processing, and in particular to an automotive seat frame conveying tray. Background Technology

[0002] In the automotive seat assembly process, the seat frame is typically transported to the assembly line via a conveyor belt. The lower part of the seat frame is fixedly connected to the upper slide rail of the slide rail assembly. A tray is mounted on the conveyor belt, and the tray contains clamps that hold the lower slide rail to secure the entire seat. In existing technology, different trays need to be adapted to different sizes of slide rail assemblies to achieve clamping. With the increasing variety of seat frames, the shortcomings of existing trays are: poor versatility, requiring the replacement of multiple trays to fit different sizes of slide rail assemblies. This results in a large number of trays being stored around the conveyor belt, occupying factory space and making tray replacement time-consuming and labor-intensive, thus slowing down production line efficiency.

Two guide ribs 39 are respectively placed on both sides of the first guide through hole 9; a square nut 38 is placed between the two guide ribs 39; the threaded rod 37 is inserted into the first guide through hole 9 and threadedly connected to the square nut 38; the first guide rail 11 is fixedly mounted on the first base plate 5; the first slider 13 is slidably connected to the first guide rail 11; the first stop block 14 is fixedly mounted on the first slider 13; the first pressure block 12 is fixedly connected to the first guide rod 15; the first guide rod 15 passes through the first stop block 14; the first spring 16 is sleeved on the first guide rod 15; the left slide rail clamp is complete. The assembly 3 includes a second base plate 17, a movable positioning block 18, a movable support block 20, a second guide rail 22, a second pressure block 23, a second slider 24, a second stop block 25, a second guide rod 26, and a second spring 27. The second base plate 17 has a second guide through hole 19 and a third guide through hole 21. The movable positioning block 18 is movably connected to the second base plate 17 through the second guide through hole 19. The movable support block 20 is movably connected to the second base plate 17 through the third guide through hole 21. The second guide rail 22 is fixedly mounted on the second base plate 17. The second slider 24 is slidably connected to the second guide rail 22. The second stop block 25 is fixedly mounted on the second slider 26. 4. The second pressure block 23 is fixedly connected to the second guide rod 26; the second guide rod 26 passes through the second stop block 25; the second spring 27 is sleeved on the second guide rod 26; the clamping motor assembly 4 includes a motor 29, a gear 30, a rack 31, and a pull rod 33; the motor 29 is fixedly mounted on the tray body 1; the gear 30 is connected to the motor 29; the first guide sleeve 28 and the second guide sleeve 32 are respectively fixedly mounted on the tray body 1; the rack 31 is fixedly mounted on the pull rod 33; the pull rod 33 is slidably connected to the first guide sleeve 28 and the second guide sleeve 32; the rack 31 meshes with the gear 30.The crossbar 34 is fixedly connected to the pull rod 33, and its two ends are respectively fixedly connected to the first slider 13 and the second slider 24.

[0015] The movable positioning pin 10 is a single unit, comprising three sections: pin 35, base 36, and threaded rod 37. The base 36 is hexagonal, facilitating tightening or loosening by a wrench. The upper surface of the base 36 is at the same height as the lower part of the lower slide rail, thus also providing support. The pin 35 and threaded rod 37 are machined on a lathe. The movable connection structure of the guide hole, guide rib, and square nut is prior art well-known to those skilled in the art. The movable connection between the movable positioning block 18, movable support block 20, and the second base plate 17 also adopts this structure. Since it is well-known to those skilled in the art, it need not be described further in this application. The tightening and loosening methods of the movable positioning block 18 and movable support block 20 are the same as those of the movable positioning pin 10, the only difference being that the movable positioning block 18 and movable support block 20 use an internal hexagonal screw instead of the threaded rod 37.

[0016] In specific operations, such as Figure 5 As shown Figure 5 The seat frame is not shown because it obstructs the view and makes it difficult to explain the coordination relationship of the various assemblies in the tray. The worker adjusts the positions of the movable positioning pin 10, movable positioning block 18, and movable support block 20 according to the type of seat frame to be clamped. Then, the seat frame falls into the tray body 1. The slide rail bracket assembly 40 connected to the lower end of the seat frame includes a left slide rail group and a right slide rail group. At this time, the left slide rail group falls into the movable positioning block 18 and the movable support block 20, and the right slide rail group falls into the first positioning block 6, the first support block 7, and the second support block 8. The pin 35 of the movable positioning pin 10 is inserted into the through hole opened on the lower slide rail. At this time, the seat frame is positioned.

[0017] The slide rail bracket assembly 40 connected to the lower end of the seat frame includes a left slide rail assembly, a right slide rail assembly, and a horizontal bracket. Both the left and right slide rail assemblies include an upper slide rail 41 and a lower slide rail 42, wherein the upper slide rail 41 is fixedly connected to the seat frame. Figure 7 (As shown in the image).

[0018] like Figure 6 As shown, the worker operates the motor 29, the gear 30 rotates counterclockwise, the rack 31 drives the pull rod 33 to move upward along the first guide sleeve 28 and the second guide sleeve 32. At the same time, the crossbar 34 pulls the first slider 13 and the second slider 24 to move upward. The first pressure block 12 cooperates with the first positioning block 6 to clamp the right slide rail, and the second pressure block 23 cooperates with the movable positioning block 18 to clamp the left slide rail. At this time, the seat frame is fixed in the tray.

[0019] like Figure 7 As shown, the conveyor belt 44 transports the seat frame 43 inside the tray body 1 to the assembly line.

[0020] When switching to other models of seat frames, if the length of the horizontal support connected to the bottom of the seat frame is different, the worker can adjust the position of the movable positioning block 18 and the movable support block 20 to adapt to it; if the length of the slide rail connected to the bottom of the seat frame is different, the worker can adjust the position of the movable positioning pin 10 to adapt to the through hole of the slide rail. The first pressure block 12 and the second pressure block 23 are provided with the first spring 16 and the second spring 27, which can adapt to the change of slide rail length without replacing the tray.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the scope of protection of the present utility model.
