Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printed circuit board production, in particular to a tooling fixture for laminating and reinforcing a printed circuit board. Background Art
[0002] For the flexible circuit board of in-vehicle lighting, considering the later application of the product, aluminum or FR-4 reinforcement needs to be added to the back of each lamp bead.
[0003] In the prior art, when laminating the reinforcement on the flexible printed circuit board of in-vehicle lighting, mainly two methods of manual lamination and limit lamination are adopted. During manual lamination, employees need to perform hole alignment lamination with the naked eye; there is a 0.2 mm offset lamination in a pure manual lamination factory; and the lamination efficiency can only reach 100 - 150 pieces. For limit lamination, a limit fixture needs to be milled and processed according to the lamination position of the product reinforcement and the shape of the reinforcement. Employees laminate the reinforcement according to the milled and processed shape of the reinforcement on the fixture, and the efficiency is 400 - 500 pcs. Due to the tolerance of more than 0.1 mm in the milling process of the limit fixture itself, and at least 0.15 mm more needs to be expanded outside the shape of the reinforcement for the limit part, there is a risk that the reinforcement cannot be put in or the lamination tolerance exceeds the standard when put in. Therefore, at present, there are problems of low efficiency, low precision, high rework rate and low output efficiency in the lamination of the reinforcement. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems of low efficiency, low precision, high rework rate and low output efficiency in the lamination of the reinforcement in the prior art, and to propose a tooling fixture for laminating and reinforcing a printed circuit board.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A tooling fixture for laminating and reinforcing a printed circuit board, including a bottom plate, a material supporting plate is arranged above the bottom plate, a slot is opened on the upper surface of the bottom plate, a pin is inserted into the slot, a clamping groove is opened on one side of the upper end of the bottom plate, a hinge is fixedly connected inside the clamping groove, the other end of the hinge is fixedly connected with the upper surface of the material supporting plate, and a through hole is opened through the upper surface of the material supporting plate.
[0006] Preferably, an interference fit is provided between the slot and the pin, and the diameter of the reinforcement hole in the circuit board is 0.15 mm larger than the diameter of the pin.
[0007] Compared with the prior art, the advantages and positive effects of the utility model are as follows:
[0008] In the present utility model, through the arrangement of the slot and the pin, during use, the circuit board is placed on the surface of the material supporting plate, the reinforcement hole is aligned with the pin for installation, and then by aligning the notch on the reinforcement with the pin and pressing, the reinforcement can be attached to the surface of the circuit board. In this way, the installation can be carried out quickly. When removing the circuit board, only one end of the material supporting plate needs to be lifted to disconnect the connection between the pin and the hole of the circuit board, and the removal can be completed. The use is relatively simple, the fitting efficiency is improved, and the fitting accuracy is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0017] Embodiment
[0018] As Figures 1-5As shown in the figure, the present utility model provides a tooling fixture for laminating and reinforcing a printed circuit board, which includes a bottom plate 1. Above the bottom plate 1, there is a material supporting plate 2. On the upper surface of the bottom plate 1, there is a slot 6. Inside the slot 6, there is a pin 4 inserted. On one side of the upper end of the bottom plate 1, there is a clamping slot 5. Inside the clamping slot 5, there is a hinge 3 fixedly connected. The other end of the hinge 3 is fixedly connected to the upper surface of the material supporting plate 2. Through holes 7 are penetrated through the upper surface of the material supporting plate 2. There is an interference fit between the slot 6 and the pin 4. The diameter of the reinforcing hole in the circuit board is 0.15 mm larger than the diameter of the pin 4. In this way, the laminating error of the reinforcement can be controlled within 0.15 mm, increasing the laminating accuracy.
[0019] Specifically, the specific settings and functions of this embodiment are as follows. Through the settings of the slot 6 and the pin 4, during use, place the circuit board on the surface of the material supporting plate 2, align the reinforcing hole with the pin 4 for installation, and then align the notch on the reinforcement with the pin 4 and press it to laminate the reinforcement on the surface of the circuit board. In this way, the installation can be carried out quickly. When removing the circuit board, just lift one end of the material supporting plate 2 to disconnect the pin 4 from the hole of the circuit board to complete the removal. The use is relatively simple, improving the laminating efficiency and having a high laminating accuracy.
[0020] The usage method and working principle of this device: During production, according to the position that needs to be reinforced, slots 6 and through holes 7 are respectively opened on the surfaces of the bottom plate 1 and the material supporting plate 2. Then insert the pin 4 into the slot 6, connect the two ends of the hinge 3 to the material supporting plate 2 and the clamping slot 5 respectively, and then make the lower surface of the material supporting plate 2 fit with the upper surface of the bottom plate 1. During use, lay the circuit board on the surface of the material supporting plate 2, connect the reinforcing hole on the surface of the circuit board to the pin 4, and then install the reinforcement on the surface of the material supporting plate 2.
