Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible circuit board production tools, specifically a flexible circuit board production fixture. Background Technology
[0002] Tooling is a production auxiliary equipment used to position, fix and protect products in production activities. In the production process of flexible circuit boards, different models of circuit boards have different shapes and sizes. In order to make the tooling applicable to these different models of circuit boards, this utility model proposes a flexible circuit board production tooling. Summary of the Invention
[0003] The purpose of this invention is to provide a flexible circuit board manufacturing tooling to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible circuit board production fixture, comprising a base and a movable block slidably disposed on the base. The base has an internal cavity, and a groove communicating with the internal cavity is formed on the top of the base. The movable block is slidably disposed on the groove, and a material trough is formed on the top of the movable block. Several mounting screw holes penetrating the movable block are formed on the material trough, and limit blocks can be installed on the mounting screw holes. Side plates are fixedly disposed on both sides of the movable block. A sliding column and an adjusting bolt are provided on the top of the base. One end of the sliding column is fixedly connected to the base, and the other end penetrates the side plate and is slidably connected to the side plate. One end of the adjusting bolt is rotatably connected to the base, and the other end penetrates the side plate and is screwed to the side plate. A sealing rubber ring is provided at the connection between the movable block and the groove to increase the airtightness of the connection.
[0005] Preferably, the material trough has multiple positioning holes around the mounting screw holes. A bolt is slidably mounted on the limiting block, passing through the limiting block and engaging with the mounting screw holes. A positioning post is provided at the bottom of the limiting block, which can be engaged with the positioning holes. The limiting block can be customized according to the shape of the flexible circuit board to be placed. By installing multiple limiting blocks in the material trough, an area is formed that allows the flexible circuit board to fit perfectly. Thus, when manufacturing new flexible circuit boards of different shapes, only the limiting blocks on the tooling need to be replaced, without needing to customize new tooling, saving manufacturing costs.
[0006] Preferably, a material suction cup can be installed on the mounting screw hole. The bottom of the material suction cup is a bolt, and the top is a suction cup. The bolt can be screwed into the mounting screw hole, which has a channel for communicating with the suction cup. The suction cup is fixed to the material tank by the bolt at the bottom of the physical suction cup. When the flexible circuit board is placed in the material tank, it comes into contact with the suction cup. When the moving block moves and a pressure difference is generated between the inner cavity of the base and the outside, the flexible circuit board is attracted and held in place.
[0007] Preferably, a plug can be screwed into the mounting screw hole. The plug can block the mounting screw hole where no limit block and material suction cup are installed, making the inner cavity a sealed space, which can generate an internal and external air pressure difference when the moving block moves.
[0008] Preferably, the base is provided with a suction cup at its bottom. The suction cup can easily attach the entire tooling to the workbench, preventing relative sliding between the two. A pull ring is provided on the outer side of the suction cup, making it easy to lift one side of the suction cup to engage the suction state.
[0009] Compared with the prior art, the beneficial effects of this utility model are: different limiting blocks can be installed on the material tank according to different shapes of circuit boards, so that the tooling can place circuit boards of different shapes. By installing plugs and material suction cups on the material tank, when the rotating adjusting bolt drives the moving block to move upward, the inner cavity space increases and forms an internal and external air pressure difference, thereby adsorbing the circuit board.

[0014] 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.
[0015] Referring to Figures (1-3), a flexible circuit board manufacturing fixture includes a base 1 and a movable block 2 slidably disposed on the base 1. The base 1 has an inner cavity 11, and the top of the base 1 has a sliding groove 12 communicating with the inner cavity 11. The movable block 2 is slidably disposed on the sliding groove 12. The top of the movable block 2 has a material groove 21, and the material groove 21 has a plurality of mounting screw holes 23 penetrating the movable block 2. Limiting blocks 3 can be installed on the mounting screw holes 23. Side plates 22 are fixedly disposed on both sides of the movable block 2. The top of the base 1 is provided with a sliding column 13 and an adjusting bolt 14. One end of the sliding column 13 is fixedly connected to the base 1, and the other end penetrates the side plate 22 and is slidably connected to the side plate 22. One end of the adjusting bolt 14 is rotatably connected to the base 1, and the other end penetrates the side plate 22 and is screwed to the side plate 22.
[0016] Multiple positioning holes 24 are provided around the mounting screw holes 23 on the material trough 21. A bolt is slidably mounted on the limiting block 3, and the bolt passes through the limiting block 3 and can be screwed into the mounting screw holes 23. A positioning post is provided at the bottom of the limiting block 3, which can be inserted into the positioning holes 24. A material suction cup 4 can be installed on the mounting screw holes 23. The material suction cup 4 has a bolt at the bottom and a suction cup at the top. The bolt can be screwed into the mounting screw holes 23 and has a channel connecting the suction cup. A plug 5 can be screwed into the mounting screw holes 23. A base suction cup 15 is provided at the bottom of the base 1.
[0017] When using this device, the limiting block 3, the material suction cup 4, and the plug 5 are installed on the mounting screw holes of the material tank 21, and the circuit board is placed in the area formed by the limiting block 3. The bottom of the circuit board is in contact with the suction cup of the material suction cup. At this time, rotating the adjusting bolt 14 causes the moving block 2 to move upward, which increases the space of the inner cavity 11 and forms an internal and external air pressure difference, so that the material suction cup adsorbs the circuit board to fix the circuit board.
[0018] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
