Description

Technical Field

[0001] This utility model relates to the field of circuit board assembly technology, and in particular to an assembly tooling for circuit board production. Background Technology

[0002] In the circuit board production process, accurately and stably assembling electronic components onto the circuit board body is a crucial step, and the fixing effect of the assembly tooling on the circuit board body directly affects the assembly quality and production efficiency.

[0003] Traditional circuit board assembly fixtures present several issues affecting the safety of securing circuit boards. Some fixtures employ simple mechanical clamping methods, relying on rigid components to directly apply clamping force to the circuit board. This method makes it difficult to precisely control the clamping force. If the clamping force is too small, the circuit board is prone to displacement due to external forces during assembly, leading to misalignment of electronic components and affecting the performance and quality of the circuit board. If the clamping force is too large, it can damage the circuit board, such as causing indentations on the surface or internal circuit breakage. This damage is particularly severe for thin and fragile circuit boards, significantly reducing the product yield.

[0004] Therefore, developing an assembly fixture for circuit board production that can ensure secure mounting is of significant practical importance. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an assembly fixture for circuit board production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An assembly fixture for circuit board production includes a support base. A fixing component for assembling the circuit board body is mounted on the top of the support base. The fixing component includes an L-shaped plate (first) and an L-shaped plate (second). The L-shaped plate (first) is fixed to the outer top wall of the support base, and a pad is welded to the outer top wall of the support base. A U-shaped seat is welded to the outer top wall of the pad. A rotating shaft is movably connected to the inner walls of both sides of the U-shaped seat. A handle is fixed to the outer circumference of the rotating shaft, and a connecting plate is movably connected to one end of the handle. A guide plate is welded to the outer top wall of the pad. A sliding plate, fixedly connected to the L-shaped plate (second) and movably connected to the side wall of the guide plate, is movably connected to the connecting plate at the end of the sliding plate away from the L-shaped plate (second). A torsion spring is installed between the side wall of the U-shaped seat and the outer circumference of the rotating shaft.

[0008] As a further embodiment of this utility model: a rolling assembly is installed on both the L-shaped plate one and the L-shaped plate two. The rolling assembly includes a frame one and a roller two, and the roller two is movably connected between the top inner wall and the bottom inner wall of the frame one.

[0009] As a further embodiment of this utility model: the rolling assembly further includes a roller and a frame, with the roller movably connected between the inner walls of both sides of the frame.

[0010] As a further embodiment of this utility model: a vertical plate is fixed to the top outer wall of the support base, and a scale plate is movably connected to a through hole on the surface of the vertical plate, with a clamping plate fixed to one end of the scale plate.

[0011] As a further embodiment of this utility model: the surface of the upright plate is threaded with a threaded rod, and one end of the threaded rod is movably connected to the second clamping plate.

[0012] As a further embodiment of this utility model: a vertical plate is fixed to the top outer wall of the support base, an electric telescopic rod is fixed to one side outer wall of the vertical plate, a pressure sensor is fixed to the output end of the electric telescopic rod, and a clamping plate one that works in conjunction with clamping plate two is fixed to the pressure sensor.

[0013] As a further embodiment of this utility model: a slide rail is fixed to the top outer wall of the support base, and a sliding seat that is movably connected to the slide rail is fixed to the bottom outer wall of the L-shaped plate.

[0014] As a further improvement of this utility model: a controller is installed on one side of the outer wall of the L-shaped plate.

[0015] Compared with the prior art, this utility model provides an assembly fixture for circuit board production, which has the following advantages:

[0016] 1. The circuit board body is clamped and fixed by L-shaped plate one and L-shaped plate two. The slide rail and sliding seat provide guidance for the movement of L-shaped plate two. The electric telescopic rod drives clamping plate one to cooperate with clamping plate two, limiting the circuit board body from multiple directions, which enhances the stability during assembly and effectively avoids assembly errors caused by the shaking of the circuit board body.

[0017] 2. A rolling component roller 2 is provided to abut against the side wall of the circuit board body, and roller 1 supports the bottom of the circuit board body. During the assembly process, when it is necessary to make a fine adjustment to the lateral position of the circuit board body, simply push the circuit board body, and roller 2 and roller 1 will roll relative to the circuit board, allowing the circuit board to move in the lateral direction.

[0018] 3. A pressure sensor is installed at the output end of the electric telescopic rod, which can monitor the pressure on the surface of the circuit board in real time when the circuit board body is clamped and fixed by clamping plates one and two. The controller is electrically connected to the pressure sensor and can control the start and stop of the electric telescopic rod according to the preset pressure value. When the pressure reaches the set value, the electric telescopic rod stops working to prevent damage to the circuit board body due to excessive clamping pressure.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] An assembly fixture for circuit board manufacturing, such as Figures 1 to 4 As shown, the device includes a support base 1. A fixing assembly for assembling the circuit board body 9 is installed on the top of the support base 1. The fixing assembly includes an L-shaped plate 7 and an L-shaped plate 27. The L-shaped plate 7 is fixed to the top outer wall of the support base 1 by bolts. A pad 19 is welded to the top outer wall of the support base 1. A U-shaped seat 18 is welded to the top outer wall of the pad 19. A rotating shaft 17 is rotatably connected to the inner walls of both sides of the U-shaped seat 18. A handle 3 is fixed to the outer circumference of the rotating shaft 17. A connecting plate 15 is slidably connected to one end of the handle 3. A guide plate 20 is welded to the top outer wall of the pad 19. A sliding plate 11, which is fixedly connected to the L-shaped plate 27, is slidably connected to the side wall of the guide plate 20. The end of the sliding plate 11 away from the L-shaped plate 27 is rotatably connected to the connecting plate 15. A torsion spring 16 is installed between the side wall of the U-shaped seat 18 and the outer circumference of the rotating shaft 17.

[0027] When electronic components need to be assembled onto the circuit board body 9, the circuit board body 9 is first fixed using a fixing component to ensure its stability during assembly. During fixing, one end of the handle 3 is rotated. As the handle 3 rotates, it drives the slide plate 11 and the L-shaped plate 27 to move laterally along the guide plate 20 via the connecting plate 15. At this time, the lateral distance between the L-shaped plate 1 and the L-shaped plate 27 gradually increases, causing one end of the circuit board body 9 to abut against the inner wall of one side of the L-shaped plate 1, and the bottom inner wall of the L-shaped plate 1 to... The bottom of the circuit board body 9 is supported. Then, the handle 3 is released and the rebound force of the torsion spring 16 causes the slide plate 11 and the L-shaped plate 27 to move towards the circuit board body 9. When the L-shaped plate 27 and the end of the circuit board body 9 away from the L-shaped plate 7 are in contact, the circuit board body 9 can be clamped and fixed by the L-shaped plate 7 and the L-shaped plate 27. During the design process, the specifications of the torsion spring 16 are limited to ensure that its elasticity will not cause damage to the circuit board body 9 after it is clamped, thus ensuring the safety of the circuit board body 9.

[0028] The top outer wall of the support base 1 is fixed with a slide rail 2 by bolts, and the bottom outer wall of the L-shaped plate 27 is fixed with a sliding seat 4 that is slidably connected to the slide rail 2 by bolts.

[0029] The slide rail 2 and the sliding seat 4 can guide the movement path of the L-shaped plate 27.

[0030] Rolling assemblies are installed on both L-shaped plate 1 7 and L-shaped plate 2 27. The rolling assembly includes frame 1 14 and roller 2 23. Roller 2 23 is rotatably connected between the top inner wall and the bottom inner wall of frame 1 14. The rolling assembly also includes roller 21 and frame 2 22. Roller 21 is rotatably connected between the inner walls on both sides of frame 2 22.

[0031] When the circuit board body 9 is clamped and fixed by L-shaped plate 7 and L-shaped plate 27, in order to facilitate the adjustment of the lateral position of the circuit board body 9, roller 23 can be used to abut against the side wall of the circuit board body 9, and roller 121 can support the bottom of the circuit board body 9. When it is necessary to adjust the lateral position of the circuit board body 9, simply push the circuit board body 9 along the side, and roller 23 and roller 121 will roll relative to the circuit board body 9, thereby facilitating the adjustment of the lateral position of the circuit board body 9.

[0032] The top outer wall of the support base 1 is fixed with a vertical plate 10 by screws. A scale plate 26 is slidably connected to a through hole on the surface of the vertical plate 10. A clamping plate 23 is fixed to one end of the scale plate 26 by screws. A threaded rod 24 is threadedly connected to the surface of the vertical plate 10, and one end of the threaded rod 24 is rotatably connected to the clamping plate 23.

[0033] When it is necessary to limit the lateral position of the circuit board body 9, the second clamping plate 13 is moved laterally along the upright plate 10 under the guidance of the scale plate 26 by rotating the threaded rod 24. The scale plate 26 is provided with scale lines, so the distance that the second clamping plate 13 moves relative to the upright plate 10 can be observed. When the second clamping plate 13 moves to the set position, the circuit board body 9 slides along the first roller 21 and the second roller 23, so that one side of the circuit board body 9 abuts against the second clamping plate 13.

[0034] The top outer wall of the support base 1 is fixed with a vertical plate 6 by bolts, and an electric telescopic rod 5 is fixed with screws on one side of the outer wall of the vertical plate 6. A pressure sensor 25 is fixed at the output end of the electric telescopic rod 5, and a clamping plate 12 that works with clamping plate 23 is fixed on the pressure sensor 25.

[0035] When one side of the circuit board body 9 comes into contact with the clamping plate 2 13, the electric telescopic rod 5 drives the clamping plate 1 12 to move laterally, and the clamping plate 1 12 comes into contact with the other side of the circuit board body 9, thereby fixing the circuit board body 9 in different directions such as front, back, left and right, ensuring its stability during assembly. The pressure sensor 25 monitors the pressure on the surface of the circuit board body 9, thereby avoiding excessive pressure on the circuit board body 9 that could cause damage.

[0036] A controller 8 is installed on one outer wall of the L-shaped plate 7;

[0037] The controller 8 is electrically connected to the electric telescopic rod 5 and the pressure sensor 25. It can receive the pressure data on the surface of the circuit board body 9 monitored by the pressure sensor 25, and control the start and stop of the electric telescopic rod 5 according to the preset value. In this way, it can accurately regulate the clamping force of the clamping plate 12 on the circuit board body 9 and prevent excessive pressure from damaging the circuit board body 9.

[0038] Working principle: When electronic components need to be assembled onto the circuit board body 9, first turn the handle 3. The connecting plate 15 causes the slide plate 11 to move the L-shaped plate 27 laterally along the guide plate 20 to increase the gap. After the circuit board body 9 is placed, release the handle 3. The torsion spring 16 rebounds and causes the L-shaped plate 7 and L-shaped plate 27 to clamp the circuit board body 9. Then push the circuit board body 9. The rollers 23 and 21 facilitate the lateral position adjustment of the circuit board body 9. Rotate the threaded rod 24 to move the clamping plate 13 laterally to the set position, so that one side of the circuit board body 9 abuts against the clamping plate 13. Then, the electric telescopic rod 5 drives the clamping plate 12 to abut against the other side of the circuit board body 9. The pressure sensor 25 monitors the pressure to prevent damage to the circuit board body 9, thereby achieving the limitation of the circuit board body 9 in different directions such as front, back, left and right.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
