Description

A flexible circuit board processing fixture Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, specifically a flexible circuit board processing fixture. Background Technology

[0002] Flexible circuit boards, also known as "flexible boards," are printed circuits made of flexible insulating substrates. Their flexible circuits provide excellent electrical performance, meet the design needs of smaller and higher density installations, and also help reduce assembly steps and enhance reliability. They can be used in related equipment for drones and aircraft data loggers.

[0003] When processing flexible circuit boards, fixtures are needed to position and support them for easy inspection. However, existing fixtures require placing the flexible circuit boards on a platform for inspection. During this process, the line of sight of the flexible circuit boards is obstructed by the pressure components, which means that workers can only observe whether the boards are installed correctly from the side of the fixture, affecting normal operation. Summary of the Invention

[0004] The purpose of this utility model is to provide a flexible circuit board processing fixture to solve the problem mentioned in the background art that the fixture requires the flexible circuit board to be placed on a platform for inspection. During the placement process, the flexible circuit board is obstructed by the line of sight of the pressure component, which easily causes the operator to only be able to observe whether it is installed in place from the side of the fixture, thus affecting normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible circuit board processing fixture, comprising:

[0006] The main body includes a base, a back plate fixedly connected to the surface of the base, a pressure-applying component mounted on the surface of the back plate, a column mounted on the surface of the pressure-applying component, a side plate movably connected to the surface of the base, a movable plate mounted on the surface of the side plate, and a plate body engagingly connected to the surface of the movable plate.

[0007] The pulling mechanism includes a first insert rod, which is fixedly connected to the surface of the side plate. A slot is provided on the surface of the movable plate. A support plate is fixedly connected to the surface of the base. A second insert rod is fixedly connected to the surface of the support plate. A spring sheet is fixedly connected to the surface of the side plate. A mounting plate is fixedly connected to the surface of the movable plate. A locking block is fixedly connected to the surface of the spring sheet. A locking hole is provided on the surface of the mounting plate.

[0008] Preferably, the first insert is inserted into the surface of the slot, the length of the first insert is the same as the length of the slot, and two sets of slots are provided, with the two sets of slots opened on both sides of the movable plate.

[0009] Preferably, the support plate is provided in two sets, and the two sets of support plates are arranged on both sides of the movable plate. The cross-section of the support plate is "L" shaped, the length of the second insert is less than the length of the first insert, and the cross-sections of the second insert and the first insert are "T" shaped.

[0010] Preferably, there are two sets of spring plates and mounting plates, which are installed on both sides of the movable plate. The mounting plates are attached to the surface of the spring plates. The surface of the locking block is hemispherical and is engaged with the surface of the locking hole. The diameter of the locking hole is the same as the diameter of the locking block.

[0011] Preferably, the surface of the base is provided with a dustproof mechanism, the dustproof mechanism including a cover plate, the cover plate being movably connected to the surface of the back plate, a fixing plate being fixedly connected to the surface of the back plate, a movable block being fixedly connected to the surface of the cover plate, a rotating block being fixedly connected to the surface of the fixing plate, a rotating hole being formed on the surface of the movable block, and a groove being formed on the surface of the cover plate.

[0012] Preferably, the fixing plate is movably connected to the surface of the movable block and the groove. Two sets of movable blocks are provided, and the two sets of movable blocks are fitted and connected to the surface of the fixing plate. The fixing plate is rotatably connected to the surface of the rotating block through a rotating hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By separating the side plate and the movable plate and connecting them with the first insert and the slot, the movable plate can be moved outward from directly below the pressure component before the flexible circuit board is placed. This allows the movable plate to slide on the surface of the first and second inserts through the slot, making it more convenient and intuitive to place the board on the movable plate. With the support plate and the connection of the locking block and the locking hole, the movable plate will not separate from the side plate before and after movement, thus limiting its range of motion.

[0016] 2. By setting a cover plate on the surface of the back plate, the fixture can be rotated around the rotating block to abut against the surface of the base when not in use, and the pressure application components, side plates and movable plates can be covered to prevent dust. This avoids the situation where dust adheres to the surface of the fixture and contaminates the surface of the plate due to prolonged disuse of the fixture. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, which show one embodiment of this utility model:

[0025] A flexible circuit board processing fixture, comprising:

[0026] The main body includes a base 1, a back plate 11 fixedly connected to the surface of the base 1, a pressure-applying component 12 mounted on the surface of the back plate 11, a column 13 mounted on the surface of the pressure-applying component 12, a side plate 14 movably connected to the surface of the base 1, a movable plate 15 mounted on the surface of the side plate 14, and a plate body 16 engagingly connected to the surface of the movable plate 15. The plate body 16 is a flexible circuit board structure and can be used in UAVs and aircraft data recorder related equipment. The side plate 14 and the movable plate 15 form a platform structure for placing the plate body 16. When processing the plate 16, it needs to be positioned on the fixture and inspected. Then, when using the fixture, the plate 16 is first placed on the movable plate 15, and then the handle on the pressure component 12 is operated so that the column 13 is pressed against the plate 16 and the side plate 14 and the movable plate 15 are pressed into the base 1. After the inspection is completed, the handle is operated again and the side plate 14 and the movable plate 15 spring back to their original positions. The length of the column 13 is sufficient and it will not be blocked by the support plate 22, the spring plate 24 and the mounting plate 25 when the pressure component 12 is pressed.

[0027] The pulling mechanism includes a first insert rod 2, which is fixedly connected to the surface of the side plate 14. A slot 21 is provided on the surface of the movable plate 15. A support plate 22 is fixedly connected to the surface of the base 1. A second insert rod 23 is fixedly connected to the surface of the support plate 22. A spring sheet 24 is fixedly connected to the surface of the side plate 14. A mounting plate 25 is fixedly connected to the surface of the movable plate 15. A locking block 26 is fixedly connected to the surface of the spring sheet 24. A locking hole 27 is provided on the surface of the mounting plate 25. The surface of the slot 21 is "T" shaped. The cross-sectional dimensions of the first insert rod 2, the slot 21, and the second insert rod 23 are all the same, and when the column 13 does not press the plate 16, the three are at the same height.

[0028] Furthermore, the first insert rod 2 is inserted into the surface of the slot 21. The length of the first insert rod 2 is the same as the length of the slot 21. There are two sets of slots 21, which are opened on both sides of the movable plate 15. With the connection between the slot 21 and the first insert rod 2, the movable plate 15 and the two sets of side plates 14 can be connected, and the movable plate 15 can move along the direction of the first insert rod 2.

[0029] Furthermore, two sets of support plates 22 are provided, and the two sets of support plates 22 are set on both sides of the movable plate 15. The cross section of the support plate 22 is "L" shaped. The length of the second insert rod 23 is less than the length of the first insert rod 2. The cross sections of the second insert rod 23 and the first insert rod 2 are "T" shaped. Under the action of the support plate 22, the second insert rod 23 can be supported and the movable plate 15 moving on its surface can be limited. The length of the first insert rod 2 can be extended through the second insert rod 23.

[0030] Furthermore, two sets of spring plates 24 and mounting plates 25 are provided. The two sets of spring plates 24 and mounting plates 25 are installed on both sides of the movable plate 15. The mounting plates 25 are attached to the surface of the spring plates 24. The surface of the locking block 26 is hemispherical. The locking block 26 is engaged with the surface of the locking hole 27. The diameter of the locking hole 27 is the same as the diameter of the locking block 26. With the connection of the locking block 26 and the locking hole 27, the spring plates 24 and the mounting plates 25 can be limited, thereby limiting the movable plate 15 to the surface of the side plate 14.

[0031] Furthermore, the surface of the base 1 is provided with a dustproof mechanism, which includes a cover plate 3. The cover plate 3 is movably connected to the surface of the back plate 11. A fixed plate 31 is fixedly connected to the surface of the back plate 11. A movable block 32 is fixedly connected to the surface of the cover plate 3. A rotating block 33 is fixedly connected to the surface of the fixed plate 31. A rotating hole 34 is opened on the surface of the movable block 32. A groove 35 is opened on the surface of the cover plate 3. The cover plate 3 is made of a transparent material and its size is sufficient to cover and dustproof the pressure component 12, the side plate 14 and the movable plate 15.

[0032] Furthermore, the fixed plate 31 is movably connected to the surface of the movable block 32 and the groove 35. Two sets of movable blocks 32 are provided, and the two sets of movable blocks 32 are attached to the surface of the fixed plate 31. The fixed plate 31 is rotatably connected to the surface of the rotating block 33 through the rotating hole 34. With the connection of the movable block 32 and the fixed plate 31, the cover plate 3 and the back plate 11 can be connected, thereby enabling the cover plate 3 to move on the surface of the fixture.

[0033] Furthermore, there are two sets of rotating blocks 33, which are installed on both sides of the fixed plate 31. The diameter of the rotating hole 34 is the same as the diameter of the rotating block 33, and the length of the groove 35 is the same as the length of the fixed plate 31. With the connection between the rotating block 33 and the rotating hole 34, the cover plate 3 can rotate around the rotating block 33.

[0034] Working principle: Before placing the plate 16 on the movable plate 15, the movable plate 15 is pulled outward so that it slides through the slot 21 onto the surfaces of the first insert 2 and the second insert 23. At the same time, the locking block 26 is squeezed by the mounting plate 25 and releases its engagement with the locking hole 27. The spring plate 24 undergoes elastic deformation. When the movable plate 15 abuts against the support plate 22, it moves out of the position directly below the pressure application component 12. At this point, the plate 16 can be placed on the movable plate 15. Then, the movable plate 15 is pushed back to its original position, and the locking block 26 re-engages in the locking hole 27. This allows the pressure application component 12 to be operated to position and limit the plate 16.

[0035] When the fixture is not in use, the cover plate 3 is moved to rotate around the rotating block 33, so that the movable block 32 moves on the fixed plate 31 and rotates on the surface of the rotating block 33 through the rotating hole 34. When the cover plate 3 covers the pressure component 12, it abuts against the surface of the base 1. At this time, the fixed plate 31 is engaged with the surface of the groove 35, thereby achieving the dust protection effect of the cover plate 3 on the fixture.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
