Description

Technical Field

[0001] The utility model relates to the technical field of mainboard patch technology, in particular to an automobile PCB mainboard patch device. Background Art

[0002] The automotive PCB motherboard is a key component in automotive electronics systems. It connects and supports the electronic components within the vehicle, ensuring the transmission of electrical signals and the distribution of power. During the placement process of the automotive PCB motherboard, a placement device is required to secure and place the components, improving placement accuracy.

[0003] After searching, the Chinese patent application number CN212812199U discloses a car PCB motherboard patch device, including a mounting base, a workbench, a mounting frame, a driving member and a patch head. The workbench is fixedly connected to the mounting base, the mounting frame is fixedly connected to the mounting base, the driving member is arranged on a side of the mounting frame close to the workbench, and the patch head is fixedly connected to the driving member.

[0004] Although the above patent not only makes the PCB board less likely to slide during the patch process, thereby avoiding inaccurate patch placement, but also avoids damage to the PCB board due to excessive pressure during operation when fixing the patch, thereby avoiding waste and loss, the following deficiencies still exist during use: 1. The device requires pulling the pull blocks in sequence to fix each part of the mainboard in turn, which is cumbersome and troublesome to operate, reducing the patch efficiency; 2. The device uses elastic parts to squeeze and fix the mainboard. Since the thickness of the mainboard is different and the spring elastic force is the same, the positioning effect is poor when facing a thinner mainboard.

[0005] Therefore, there is an urgent need for an automotive PCB motherboard patch device to solve the above problems. Utility Model Content

[0030] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0031] like Figure 1-6 As shown, the present embodiment proposes an automotive PCB motherboard patch device, including a mounting base 1, a top wall of the mounting base 1 having symmetrically distributed slide grooves 9, a top wall of the mounting base 1 fixedly connected to a guide base 13, and a top wall of the mounting base 1 further fixedly connected to a mounting frame 3, and further comprising:

[0032] The fixing frame 12 is fixedly connected to the top wall of the mounting base 1;

[0033] The adjusting and fixing assembly includes a slider 10 that is slidably connected to the inner wall of the slide groove 9, and the top wall of the slider 10 is fixedly connected to the side plate 22. The inner wall of the side plate 22 is threadedly connected to a transverse bidirectional screw 19, and the outer wall of the transverse bidirectional screw 19 is fixedly connected to the driven circular gear 18. The top wall of the side plate 22 is slidably connected to a slide plate 23 symmetrically distributed, and the inner wall of the slide plate 23 is slidably connected to a linkage frame 24. The inner wall of the linkage frame 24 is threadedly connected to a vertical bidirectional screw 27, and the vertical bidirectional screw 27 is rotatably connected to the fixed frame 12, and the outer wall of the vertical bidirectional screw 27 is fixedly connected to the driven bevel gear 28. The transverse bidirectional screw 19 is threadedly engaged with the side plate 22. In fact, the side plate 22 slides in the slide groove 9 through the slider 10 to adjust the distance between the side plates 22, thereby fixing the two sides of the main board to prevent the main board position from shifting. At the same time, during the movement of the side plate 22, the slide plate 23 will always slide along the linkage frame 24 to maintain the connection between the linkage frame 24 and the side plate 22;

[0034] The motor 4 is fixedly connected to the top wall of the mounting frame 3. The output end of the motor 4 is fixedly connected to the screw rod 5, and the end of the screw rod 5 away from the output end of the motor 4 is rotatably connected to the mounting frame 3, and the screw rod 5 is driven to rotate by the output end of the motor 4;

[0035] The linkage adjustment conversion component is arranged on the top wall of the mounting seat 1.

[0036] like Figure 3-5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the linkage adjustment conversion assembly includes a fixed plate 11 symmetrically fixedly connected to the top wall of the mounting seat 1, and the fixed plate 11 is rotatably connected to the horizontal bidirectional screw 19, the outer wall of the fixed plate 11 on the right side is rotatably connected to the driving circular gear 17, and the outer wall of the driving circular gear 17 is meshed with the outer wall of the driven circular gear 18, and the end of the fixed plate 11 on the right side away from the driving circular gear 17 is rotatably connected to the driving bevel gear 16, and the outer wall of the driving bevel gear 16 is meshed with the driven bevel gear 28, and the driving bevel gear 16 is connected to the driving circular gear 18. The inner wall of the gear 17 is provided with a limiting groove 20, and the inner wall of the limiting groove 20 is slidably connected to the limiting block 21. The end of the limiting block 21 away from the limiting groove 20 is fixedly connected to the driving rod 15. The driving rod 15 is pulled, and the driving rod 15 slides in the guide seat 13 through the guide block 14. The driving rod 15 moves and pulls the limiting block 21 to slide in the limiting groove 20 in the driving circular gear 17, and slides into the limiting groove 20 in the driving bevel gear 16. In this way, the driving circular gear 17 or the driving bevel gear 16 can be flexibly driven to rotate according to needs, so that the height of the side plate 22 or the linkage frame 24 can be flexibly adjusted.

[0037] like Figure 3-4 As shown, as a preferred embodiment, based on the above method, further, the outer wall of the driving rod 15 is rotatably connected to a guide block 14, and the guide block 14 is slidingly connected to the guide seat 13, and the guide block 14 provides rotational support force for the rotation of the driving rod 15.

[0038] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the inner wall of the linkage frame 24 is slidably connected with symmetrically distributed extrusion rods 25, the outer wall of the extrusion rod 25 is provided with a spring 26, and the spring 26 is fixedly connected to the linkage frame 24, and the end of the spring 26 away from the linkage frame 24 is fixedly connected to the extrusion rod 25, and the main board is fixed by squeezing the main board through the extrusion rod 25.

[0039] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the inner wall of the mounting frame 3 is slidably connected to a moving block 6, and the moving block 6 is transmission-connected to the screw rod 5, the outer wall of the moving block 6 is fixedly connected to a connecting plate 7, and the outer wall of the connecting plate 7 is fixedly connected to a symmetrically distributed patch device 8, and the moving block 6 is driven by the screw rod 5 to slide in the mounting frame 3, thereby driving the connecting plate 7 to move, and then driving the patch device 8 to move, so that the patch operation is performed through the device to improve the accuracy of the patch.

[0040] like Figure 1As shown, as a preferred embodiment, on the basis of the above method, further, the outer wall of the mounting base 1 is fixedly connected with symmetrically distributed leveling legs 2, which provide support force for the equipment and can adjust the horizontal position of the equipment.

[0041] Specifically, when the automobile PCB motherboard patch device is in use: the handheld driving rod 15 is rotated along the guide block 14, thereby driving the limit block 21 to rotate, and the limit block 21 squeezes the limit groove 20 to drive the driving circular gear 17 to rotate, and then the meshing transmission driven circular gear 18 is rotated, thereby driving the horizontal bidirectional screw 19 to rotate along the fixed plate 11, and the horizontal bidirectional screw 19 is threadedly matched with the side plate 22. In fact, the side plate 22 slides in the slide groove 9 through the slider 10 to adjust the distance between the side plates 22. At the same time, the side plate 22 will drive the slide plate 23 to always slide along the linkage frame 24 during the movement of the side plate 22, in order to maintain the connection between the linkage frame 24 and the side plate 22. When both sides of the motherboard are fixed, pull the driving rod 15, and the driving rod 15 slides in the guide seat 13 through the guide block 14. The driving rod 15 moves and pulls the limit block 21 to slide in the limit groove 20 in the driving circular gear 17 and slide into the limit groove 20 in the driving bevel gear 16. At this time, the driving rod 15 is stopped and then the driving rod 15 is rotated. The limit block 21 is driven to rotate by the rotation of the driving rod 15, and then the limit groove 20 is squeezed to drive the driving bevel gear 16 to rotate, and then the meshing transmission driven bevel gear 28 is rotated. Further, the driven bevel gear 28 drives the vertical bidirectional screw 27 to rotate in the fixed frame 12, and the threaded cooperation between the vertical bidirectional screw 27 and the linkage frame 24 drives the linkage frame 24 to slide in the side plate 22 through the slide plate 23, so as to adjust the height of the linkage frame 24, that is, to adjust the height of the extruding rod 25 of the extrusion positioning mainboard, so as to adapt to mainboards of different thicknesses and prevent the poor fixing effect of extrusion positioning only by the spring 26.

[0042] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
