Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible circuit board processing technology, specifically to a jig transfer mechanism for flexible circuit boards. Background Technology
[0002] When flexible printed circuit boards (FPCBs) need to be processed at different workstations, such as from the printing workstation to the surface mount workstation and then to the reflow soldering workstation, the fixture needs to carry the FPCBs between the workstations to achieve different processing operations and ensure that the FPCBs gradually complete various production processes.
[0003] Meanwhile, when processing flexible circuit boards at each workstation, it is necessary to consider the different changes in the position of the flexible circuit boards at different workstations. The traditional jig transfer structure uses a specific track for transportation. However, the orientation of the jig changes with the track. In order to adjust the angle of the jig at each workstation, it is often necessary to change the direction of the track, which increases the complexity of the track structure and is likely to increase the equipment failure rate. Alternatively, an angle adjustment mechanism for the jig can be installed at each workstation. However, it is difficult for the angle adjustment mechanisms at each workstation to be linked, which increases the difficulty of angle adjustment at each workstation and thus affects the accuracy. Summary of the Invention
[0004] The purpose of this utility model is to provide a fixture transfer mechanism for flexible circuit boards. By movably connecting the fixture body to the synchronous belt, the angle of the fixture body can be easily adjusted at the top of the synchronous belt. Then, by using the rack plate installed at the workstation and the adjusting gear on the connecting shaft, the fixture body can be pre-adjusted for turning as it enters the workstation. This ensures that the angle of the fixture body is automatically aligned after it is transferred to the designated position. At the same time, after the fixture body leaves the workstation, the fixture body is reset with the synchronous belt as the reference through the automatic angle reset component. This allows each workstation to independently adjust the angle, thereby reducing the difficulty of adjusting the angle of the fixture body at each workstation and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a jig transfer mechanism for flexible circuit boards, comprising:
[0006] Synchronous belts used to transfer the fixture body between various workstations;
[0007] The bottom of the fixture body is movably connected to the mounting cylinder at the top of the timing belt via a connecting shaft. An adjusting gear that meshes with a rack plate installed at each work station is fixed on the outside of the connecting shaft. The adjusting gear and the rack plate work together to adjust the position of the fixture body.
[0008] An automatic angle reset component is provided between the connecting shaft and the mounting cylinder.
[0009] Preferably, the end of the connecting shaft away from the fixture body extends into the inner cavity of the mounting cylinder and is rotatably connected by a bearing. A connecting column is fixed at the bottom of the mounting cylinder, and the end of the connecting column away from the mounting cylinder is fixedly connected to the top of the timing belt. The connecting column and the connecting shaft are coaxially arranged with the mounting cylinder.
[0010] Preferably, the automatic angle reset component includes a torsion spring, one end of which is fixed to the outside of the connecting shaft, and the other end of which is fixed to the inner wall of the mounting cylinder. An angle deflection protection component is also provided between the connecting shaft and the mounting cylinder.
[0011] Preferably, the angle deflection protection component includes a guide groove formed at the bottom of the inner cavity of the mounting cylinder, and a guide post slidably mounted on the connecting shaft is disposed in the guide groove.
[0012] Preferably, a square post is fixed to the outer side of the connecting shaft, a movable ring is slidably disposed on the outer side of the square post, and the guide post is fixed to the outer side of the movable ring.
[0013] Preferably, a limiting groove is formed annularly on the inner sidewall of the mounting cylinder, and a limiting block connected to the square column is slidably disposed in the inner cavity of the limiting groove.
[0014] Preferably, the rack plate includes a straight rack plate and a curved rack plate, and the guide groove is a curved groove with a deflection angle of 360 degrees.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention uses a connecting shaft and a mounting cylinder to movably connect the fixture body to the synchronous belt, allowing the fixture body to move with the synchronous belt and also enabling autonomous angle adjustment. This facilitates the fixture body to meet the processing requirements of various workstations for flexible circuit boards. Furthermore, the adjusting gear on the connecting shaft cooperates with the rack plate on the workstation to facilitate the adjustment of the fixture body's orientation before entering the workstation. Simultaneously, after the fixture body leaves the workstation, its angle relative to the synchronous belt can be reset, allowing for precise adjustment of the fixture at the next workstation and reducing the difficulty of moving and adjusting the fixture body.
[0017] This invention, by limiting the structure of the guide groove, can meet the need for omnidirectional rotation adjustment of the fixture body, and can also cooperate with the torsion spring to adjust the position of the fixture body in a static state, avoiding the jig body from shaking and affecting the adjustment difficulty.

Detailed Implementation
[0024] 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.
[0025] This utility model provides, for example Figures 1-5 A fixture transfer mechanism for flexible printed circuit boards, as shown, includes:
[0026] Synchronous belt 2 is used to transfer the fixture body 1 between various workstations;
[0027] The bottom of the fixture body 1 is movably connected to the mounting cylinder 4 at the top of the timing belt 2 via the connecting shaft 3. An adjusting gear 5 is fixed on the outside of the connecting shaft 3, which meshes with the rack plate 6 installed at each work station. The adjusting gear 5 and the rack plate 6 work together to drive the adjustment of the position of the fixture body 1.
[0028] An angle automatic reset component 7 is provided between the connecting shaft 3 and the mounting cylinder 4;
[0029] The fixture body 1 and the timing belt 2 are movably connected by the connecting shaft 3 and the mounting cylinder 4, so that the fixture body 1 can be moved with the timing belt 2 and can also be adjusted at its own angle. This makes it convenient for the fixture body 1 to meet the processing requirements of each workstation for the flexible circuit board. Then, the adjusting gear 5 on the connecting shaft 3 cooperates with the rack plate 6 on the workstation to make it easy to adjust the position of the fixture body 1 before entering the workstation. At the same time, after the fixture body 1 leaves the workstation, it can be reset at its angle relative to the timing belt 2, which makes it easy to make precise adjustments to the fixture at the next workstation and reduces the difficulty of moving and adjusting the fixture body 1.
[0030] Among them, such as Figure 2-3 As shown:
[0031] The end of the connecting shaft 3 away from the fixture body 1 passes through the inner cavity of the mounting cylinder 4 and is rotatably connected by a bearing. A connecting column is fixed at the bottom of the mounting cylinder 4, and the end of the connecting column away from the mounting cylinder 4 is fixedly connected to the top of the timing belt 2. The connecting column, the connecting shaft 3, and the mounting cylinder 4 are coaxially arranged. The connecting shaft 3 and the mounting cylinder 4 are rotatably connected by the bearing, which provides conditions for multi-directional adjustment of the fixture body 1. At the same time, the coaxiality of the connecting column, the mounting cylinder 4, and the connecting shaft 3 can avoid positional changes caused by rotation during the angle adjustment of the fixture.
[0032] Furthermore, such as Figure 3-4 As shown:
[0033] The angle automatic reset component 7 includes a torsion spring 71. One end of the torsion spring 71 is fixed to the outside of the connecting shaft 3, and the other end of the torsion spring 71 is fixed to the inner wall of the mounting cylinder 4. An angle deflection protection component 72 is also provided between the connecting shaft 3 and the mounting cylinder 4. Through the elastic energy storage capacity of the torsion spring 71, the connecting shaft 3 is limited, causing the connecting shaft 3 to deflect in one direction. In conjunction with the angle deflection protection component 72, the orientation of the fixture body 1 is protected, preventing the angle of the fixture body 1 from changing and affecting the accuracy and difficulty of adjustment.
[0034] Preferred, such as Figure 4-5 As shown:
[0035] The angle deflection protection component 72 includes a guide groove 721 formed at the bottom of the inner cavity of the mounting cylinder 4. A guide post 722 is slidably disposed in the guide groove 721 and movably mounted on the connecting shaft 3. By sliding the guide post 722 in the guide groove 721, the connecting shaft 3 can be deflected. The position of the guide groove 721 is used to limit the static angle of the fixture body 1, providing a basis for angle adjustment at each station and avoiding increasing the difficulty of adjustment at the next station after the angle of each station is adjusted.
[0036] It is worth noting that, such as Figure 3-4 As shown:
[0037] A square post 8 is fixed to the outside of the connecting shaft 3. A movable ring 9 is slidably arranged on the outside of the square post 8. The guide post 722 is fixed to the outside of the movable ring 9. The movable ring 9 slides on the outside of the square post 8, which facilitates the sliding of the guide post 722 in the guide groove 721, reduces the squeezing force between the guide groove 721 and the guide post 722, and improves flexibility.
[0038] In a further preferred embodiment, such as Figure 3-5 As shown:
[0039] A limiting groove 10 is formed in a ring on the inner side wall of the mounting cylinder 4. A limiting block 11 connected to the square column 8 is slidably arranged in the inner cavity of the limiting groove 10. Through the cooperation of the limiting groove 10 and the limiting block 11, the square column 8 is conveniently limited, ensuring the stability of the square column 8 and preventing the square column 8 from shaking on the outside of the connecting shaft 3, thereby causing the guide column 722 to shake.
[0040] In addition, such as Figure 1 and Figure 5 As shown:
[0041] The rack plate 6 includes a straight rack plate 6 and a curved rack plate 6. The guide groove 721 is a curved groove with a deflection angle of 360 degrees. By limiting the structure of the rack plate 6, the straight rack plate 6 and the curved rack plate 6 are used together to facilitate the movement trajectory of the synchronous belt 2, thereby reducing the complexity of the synchronous belt 2 track. At the same time, by limiting the shape and deflection angle of the guide groove 721, multi-directional adjustment of the fixture body 1 can be achieved, and the position of the fixture body 1 can be limited.
[0042] In practical use, the synchronous belt 2 is driven by the synchronous pulley, causing the synchronous belt 2 to move the fixture body 1 between various workstations. Then, according to the specific stopping position and angle of the fixture body 1 at each workstation, the rack plate 6 is installed on the workstation. When the synchronous pulley drives the synchronous belt 2 to rotate, the adjusting gear 5 on the fixture body 1 contacts the rack plate 6 before the synchronous belt 2 enters the workstation. Subsequently, with the joint cooperation of the rack plate 6 and the synchronous belt 2, the adjusting gear 5, during the transfer to the processing position, drives the fixture body 1 to rotate via the connecting shaft 3, adjusting the angle of the fixture body 1 to meet the processing orientation requirements of each workstation. Simultaneously with the rotation of the rack plate 6, the adjusting gear 5... The moving connecting shaft 3 rotates, and at the same time, the rotation of the connecting shaft 3 drives the torsion spring 71 to deform, realizing the energy storage of the torsion spring 71. When the fixture body 1 leaves the station and moves to the next station, the adjusting gear 5 separates from the rack plate 6. At this time, the torsion spring 71 releases its energy to rotate the fixture body 1 in the opposite direction. Then, the connecting shaft 3 rotates in the guide groove 721 through the guide post 722 to rotate in the opposite direction. When the guide post 722 stops at one end of the guide groove 721, it works with the unreleased elastic force of the torsion spring 71 to limit the orientation of the connecting shaft 3 and the fixture body 1, thereby keeping the fixture body 1 in the initial position with the synchronous belt 2 as the reference. This makes it convenient to adjust the angle of the fixture body 1 at the next station, reducing the difficulty and improving the accuracy.
