Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing equipment technology, specifically a jig for removing the cover of a rigid-flex board. Background Technology

[0002] A rigid-flex PCB is a highly reliable and flexible printed circuit board made with polyimide as the substrate. It combines flexible and rigid circuit boards through processes such as lamination, according to relevant process requirements, to form a circuit board with both FPC and PCB characteristics.

[0003] The current method for removing the cover of a rigid-flex PVC board typically involves using an ejector mechanism to push the cover off the board. However, the ejector components of the existing ejector mechanism cannot meet diverse needs. Furthermore, the ejector components are fixed to the ejector mechanism with bolts or are directly integrally molded, making it cumbersome to disassemble and replace with suitable ejector components. In addition, when the ejector components are ejected, the cover may stick to the ejector components, making it impossible to remove the cover effectively, which has limitations.

[0004] The reason for this problem is that due to the diversity in the production of rigid-flex PCBs, their shapes, sizes, and required ejector components often vary. Therefore, the ejector components required for the unpacking process also differ significantly for each type of rigid-flex PCB. These ejector components are bolted to the ejection mechanism or are integrally molded. This makes disassembling and replacing ejector components suitable for different rigid-flex PCBs relatively cumbersome and time-consuming. Since the cover plate and the rigid-flex PCB are usually glued together, this adhesive method generates adhesive force during the ejection process. When the ejector component is ejected, this adhesive force causes the cover plate to partially or completely stick to the ejector component, thus preventing smooth unpacking. Therefore, we propose a jig for unpacking rigid-flex PCBs to solve the above problems. Utility Model Content

It solves the problems that the ejector of the existing ejector mechanism cannot meet diverse needs, and that the ejector is fixed to the ejector mechanism with bolts or directly integrally formed, making it troublesome to disassemble and replace the suitable ejector. In addition, when the ejector is ejected, the cover plate will stick to the ejector and cannot be effectively lifted, which has limitations.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a jig for opening and closing a rigid-flex PCB, comprising a jig body, wherein the jig body is composed of an upper jig and a lower jig, and a quick-release unit is provided inside the jig body, wherein the quick-release unit includes;

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example 1

[0033] This utility model discloses a jig for removing the cover of a rigid-flex plate. According to the attached... Figure 1 , 3 As shown in Figures 4 and 5, the fixture body 1 is composed of an upper fixture 11 and a lower fixture 12. The fixture body 1 is provided with a quick-release unit 2 inside. The quick-release unit 2 includes:

[0034] Top block 21, which is located below the upper fixture 11, is used to push out the material;

[0035] The clip 22 is located inside the top block 21, and the top block 21 is quickly assembled with the upper fixture 11 via the clip 22.

[0036] An air pump 24 is disposed on one side of the upper fixture 11;

[0037] The conduit 23 is located on one side of the air pump 24, and the air pump 24 is connected to the conduit 23.

[0038] A rotating block 14 is rotatably connected to the top of the lower fixture 12. A threaded rod 15 is installed inside the rotating block 14, and the threaded rod 15 is threadedly connected to the rotating block 14. An electric telescopic rod 13 is installed inside the upper fixture 11. A support plate 25 is fixedly connected to the bottom of the electric telescopic rod 13. The electric telescopic rod 13 is used to push the support plate 25 to move towards the lower fixture 12. Insert rods 26 are arranged in a rectangular array at the bottom of the support plate 25, and the insert rods 26 are movably inserted into the top block 21. Inside, the locking component 22 includes: a pull rod 221, which is movably inserted into the inside of the top block 21; a sliding plate 222, which is fixedly connected to the end of the pull rod 221 and slidably connected to the inside of the top block 21; the locking component 22 also includes: a spring 223, one end of which is fixedly connected to both ends of the sliding plate 222 and the other end of which abuts against the inner wall of the top block 21; and an insert block 224, which is fixedly connected to one side of the pull rod 221 and movably locked into the inside of the insert rod 26.

[0039] In this embodiment, when it is necessary to disassemble the top block 21, first remove the guide tube 23 from one side of the top block 21. Since the guide tube 23 and the top block 21 are threadedly connected, the guide tube 23 can be removed by rotating it counterclockwise. At this time, pull the pull rod 221 to both sides. The slide plate 222 is pulled and slides away from the central axis, and the spring 223 is tightened, so that the insert block 224 is disengaged from the inside of the insert rod 26. At this time, pull the top block 21 down to remove the top block 21.

The threaded rod 15 is unscrewed, and the rotating block 14 is rotated to one side to place the rigid-soft bonding plate into the lower fixture 12. The rotating block 14 is rotated back to its original position, and the threaded rod 15 is screwed on so that the end of the threaded rod 15 abuts against the rigid-soft bonding plate. Since the bottom of the threaded rod 15 is provided with a rubber block, the rigid-soft bonding plate will not be damaged when the threaded rod 15 fixes the position of the rigid-soft bonding plate, thus meeting the user's needs.

[0040] Example 2

[0041] This utility model discloses a jig for opening and closing a rigid-flex PVC board. More specifically, based on Embodiment 1, it is provided according to the attached... Figure 2 , 3 As shown, it includes a fixture body 1, which is composed of an upper fixture 11 and a lower fixture 12. A quick-release unit 2 is provided inside the fixture body 1. The quick-release unit 2 includes:

[0045] The conduit 23 is located on one side of the air pump 24, and the air pump 24 is connected to the conduit 23.

[0046] The top block 21 is fixedly connected to a fixing plate 27, which divides the interior of the top block 21 into an upper working area and a lower working area. The bottom of the top block 21 is fixedly connected to a protrusion 28, which communicates with the lower working area. The conduit 23 also communicates with the lower working area.

[0047] In this embodiment, the top block 21 is pushed to move downward towards the fixture 12 by the electric telescopic rod 13. The protrusion 28 pushes out the cover plate at the bottom of the flexible and rigid bonding plate through the pre-drilled hole in the flexible and rigid bonding plate. At this time, the air pump 24 is started. The air pump 24 blows gas into the interior of the lower working area through the conduit 23 and blows it out through the hole inside the protrusion 28, blowing off the cover plate so that it does not stick to the protrusion 28 and affect the normal use of the device, thus meeting the user's needs.
