Technical Field
[0001] The utility model relates to the technical field of mechanical molds, and particularly relates to a special fixture for a PCB printed board splitting tooling. Background Technique
[0002] The splitting of PCB printed boards is a main component for high-integrated circuits to achieve functions. At present, our company and most domestic manufacturers are using SMT for chip mounting. When using the traditional SMT for splitting, manual mechanical splitting is adopted, and the fixing and limiting are inaccurate, greatly increasing human errors and the scrap rate of products, thus increasing the production cost. Therefore, in view of the above problems, a special fixture for a PCB printed board splitting tooling is designed to better meet the actual use requirements. Content of the Utility Model
[0003] The purpose of the utility model is to provide a special fixture for a PCB printed board splitting tooling to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A special fixture for a PCB printed board splitting tooling, including a bottom plate and a cover plate. The bottom plate is evenly provided with positioning grooves, and mounting grooves opened on the bottom plate are symmetrically arranged before and after the positioning grooves. The positioning grooves and the PCB printed board body are nested and connected. A cover plate is arranged above the PCB printed board body, and a cutting groove is opened on the cover plate.
[0005] Preferably, a cushion block fixed on the bottom plate is arranged in the positioning groove, and the cushion block contacts the PCB printed board body to achieve a supporting effect. Through the effect of the cushion block, the PCB printed board body can be in a suspended installation state in the positioning groove, avoiding damage to the electronic components on the surface of the PCB printed board body.
[0006] Preferably, a protective rubber pad is nested and installed in the mounting groove, and the protective rubber pad contacts the PCB printed board body to achieve a protective effect. Through the effect of the protective rubber pad, the protective effect of the PCB printed board body can be realized, avoiding damage to the contact surface of the PCB printed board body.
[0007] Preferably, mounting holes are symmetrically opened on the left and right of the cover plate, and the mounting holes are in a strip structure. A groove matching with the PCB printed board body is opened on the cover plate. Through the effect of the mounting holes, the mounting position of the cover plate can be adjusted back and forth to ensure the accurate cooperation between the cover plate and the bottom plate.
[0008] Preferably, two cutting grooves are provided, and the distance between the two cutting grooves is equal to the width of the PCB printed board body. By limiting the distance between the two cutting grooves, a basic guarantee can be provided for the splitting operation of the PCB printed board body.
[0009] Preferably, the cutting groove is connected to the avoidance hole opened on the cover plate, and the avoidance hole is of a semicircular structure. Through the above structure, the normal operation of the PCB printed board body splitting operation can be ensured.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The special fixture for the PCB printed board splitting tooling has a simple overall structure and is convenient for disassembly and assembly. It can accurately realize the fixing and limiting functions of the PCB printed board body during the splitting of the PCB printed board body, thus greatly reducing human errors and the scrapping probability of products, and effectively reducing the production cost.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: A special fixture for the PCB printed board splitting tooling, including a bottom plate 1 and a cover plate 6. The bottom plate 1 is evenly provided with positioning grooves 2. Installation grooves 3 opened on the bottom plate 1 are symmetrically arranged before and after the positioning grooves 2. The positioning grooves 2 and the PCB printed board body 5 are in a nested connection. A cover plate 6 is arranged above the PCB printed board body 5, and a cutting groove 7 is opened on the cover plate 6.
[0017] A spacer block 201 fixed to the bottom plate 1 is provided in the positioning groove 2, and the spacer block 201 contacts the PCB printed board body 5 to achieve a supporting effect; a protective rubber pad 4 is nested in the installation groove 3, and the protective rubber pad 4 contacts the PCB printed board body 5 to achieve a protective effect; mounting holes 601 are symmetrically arranged on the left and right of the cover plate 6, and the mounting holes 601 are strip-shaped structures. A groove matching with the PCB printed board body 5 is provided on the cover plate 6; there are two cutting grooves 7, and the distance between the two cutting grooves 7 is equal to the width of the PCB printed board body 5; the cutting groove 7 is connected to an avoidance hole 701 provided on the cover plate 6, and the avoidance hole 701 is a semi-circular structure;
[0018] When using this special fixture for PCB printed board splitting tooling, as Figures 1 - 3 shown, first fix the bottom plate 1 and the cover plate 6 on the workbench of the splitting press through screws or positioning pins. Through the function of the mounting holes 601, it is convenient to finely adjust the position of the cover plate 6 to ensure that the cover plate 6 and the bottom plate 1 can be accurately matched. Then, nest and match the PCB printed board body 5 to be split with the positioning groove 2 to realize the positioning and installation of the PCB printed board body 5. At this time, the lower end surface of the PCB printed board body 5 is in contact with the spacer block 201 and is in a suspended state, avoiding damage to the electronic components on the lower end surface of the PCB printed board body 5. Then, drive the cover plate 6 to apply pressure through the pneumatic system of the splitting machine so that the PCB printed board body 5 to be split can be accurately and reliably fixed on the fixture. After confirmation, start the splitting machine to divide the PCB printed board body 5 through the cutting groove 7. This is the working principle of this special fixture for PCB printed board splitting tooling.
