Description

Technical Field

[0001] This utility model belongs to the field of PCB board manufacturing technology, and specifically relates to a multifunctional PCB board material frame. Background Technology

[0002] During the PCB manufacturing process, there is a power-on inspection step, which is usually completed using PCB power-on inspection equipment. The power-on inspection equipment requires PCB material frames for loading and unloading. PCB material frames are special storage tools used for the neat storage and transportation of PCBs. They have strict dimensions and structures to protect the PCBs from bending or external impacts and ensure their safety.

[0003] Depending on the different market demands, PCB boards come in various sizes. To meet the needs of neat storage and transportation of PCB boards, PCB frames of different sizes are required. However, there are many PCB frames of different sizes, which take up a lot of space, are difficult to store, and are costly. Therefore, how to use a single PCB frame to neatly store and transport PCB boards of different sizes is a technical problem that urgently needs to be solved. Utility Model Content

[0004] To address the problems of existing technologies, this utility model proposes a multifunctional PCB board material frame, which solves the problem that current PCB board material frames cannot accommodate PCB boards of different sizes.

[0005] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. A multifunctional PCB board frame according to this utility model includes a central plate, side plates symmetrically arranged on both sides of the central plate, several guide support columns, and a retaining edge. The central plate has two end-fixed plates extending along its length. The several guide support columns are located on the inner side of the side plates near the central plate. The side plates are connected to the end-fixed plates via the guide support columns, forming two cavities between the side plates and the central plate for placing the PCB board. The guide support columns are slidably inserted into the end-fixed plates. Several guide grooves for limiting the PCB board are symmetrically arranged on the two inner walls extending along the length of the cavities. The retaining edge is located at the bottom of the cavity.

[0006] Furthermore, the two end fixing plates are equipped with limiting components for guiding and limiting the support columns.

[0007] Furthermore, the limiting component can be either a set screw or a bolt.

[0008] Furthermore, the side plates and center plate are provided with several slots.

[0009] Furthermore, handles are provided on the fixing plates at both ends.

[0010] Furthermore, clamp bushings are provided at the bottom of the two end fixing plates.

[0011] Furthermore, the top of the guide groove is connected to an expansion groove, which is shaped like an outward V and has an upward sloping bottom.

[0012] Furthermore, both the side panels and the center panel are made of anti-static materials.

[0013] In summary, this utility model allows for adjustment of the distance between the side plate and the center plate via guide support columns, thereby adjusting the size of the cavity. Furthermore, the two cavities can be of different sizes, enabling it to accommodate PCBs of varying dimensions. Guide grooves are designed on the side and center plates to limit, protect, neatly store, and transport the PCBs, preventing bending or external impacts. This material frame structure is simple, low-cost, and highly compatible, reducing the number of material frames required by enterprises, facilitating enterprise management, and significantly improving economic efficiency.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Please see Figure 1 , Figure 2 A multifunctional PCB board frame includes a central plate 6, side plates 1 symmetrically arranged on both sides of the central plate 6, and several guide support columns 2.

[0021] The center plate 6 has two end fixing plates 4 extending along its length. The guide support columns 2 are located on the inner side of the side plate 1 near the center plate 6 and at both ends extending along the length of the side plate 1. In this embodiment, each side plate 1 has two guide support columns 2 at both ends. The two guide support columns 2 are symmetrically arranged along the center line of the side plate 1 along its length. The side plate 1 is connected to the end fixing plates 4 through the guide support columns 2 so that two cavities for placing PCB boards are formed between the side plate 1 and the center plate 6. The guide support columns 2 are slidably inserted into the end fixing plates 4. The distance between the two side plates 1 and the center plate 6 can be adjusted by sliding the guide support columns 2, thereby adjusting the size of the cavity to accommodate PCB boards of different sizes. At the same time, the end fixing plates 4 are provided with limiting components for limiting the guide support columns 2. The limiting components can be one of set screws 5 and bolts, which can limit the guide support columns 2, prevent the side plates 1 from slipping, and stabilize the overall structure. In this embodiment, eight limiting components are used, four of which are provided on one end fixing plate 4, two of which are located at the top of the end fixing plates 4 and two at the bottom.

[0022] On the two inner walls extending along the length of the cavity (the inner walls of the cavity are composed of the two side walls extending along the length of the central plate 6 and the inner side walls of the corresponding side plates 1, i.e., the guide grooves 7 are provided on the two side walls of the central plate 6 and the inner side walls of the side plates 1), several guide grooves 7 for limiting the PCB board are symmetrically provided. The guide grooves 7 can limit, protect, neatly store and transport the PCB board, prevent the PCB board from bending or being hit by external collisions, and the top of the guide grooves 7 is connected to the expansion grooves 10. The expansion grooves 10 are outward V-shaped and the bottom of the expansion grooves 10 is an upward sloping surface, which can provide a guiding function when the PCB board is inserted into the guide grooves 7, making it easy for the PCB board to be inserted into the guide grooves 7.

[0023] Please see Figure 3 , Figure 4 The bottom of the cavity is provided with a retaining edge 9, which can limit the bottom of the PCB board and prevent the PCB board from falling out.

[0024] The side plate 1 and the center plate 6 are also provided with several sets of slots 11. Each set of slots 11 is distributed between two adjacent guide slots 7. Each set of slots 11 includes two holes and is symmetrically arranged about the center line extending along the length direction of the side plate 1 and the center plate 6. This can reduce the overall weight of the device, facilitate handling, and reduce production costs.

[0025] Handles 3 are provided on the two end fixing plates 4, which make it easy for manual labor and handling equipment to grip the material frame and make it convenient to use;

[0026] The bottom of the two end fixing plates 4 is provided with clamp bushings 8. One of the two end fixing plates 4 is provided with two clamp bushings 8, and the other two end fixing plates 4 is provided with one clamp bushing 8. It can play a positioning role when the PCB material frame interacts with the PCB board power-on inspection equipment, and ensure the accuracy of the PCB material frame on the PCB board power-on inspection equipment.

[0027] Both side panel 1 and center panel 6 are made of antistatic material, which can be selected according to actual needs, as long as the antistatic properties of side panel 1 and center panel 6 can be guaranteed. In this embodiment, the material used is antistatic bakelite.

[0028] A method for using a multi-functional PCB board frame:

[0029] Adjust the distance between the side plate 1 and the center plate 6 according to the size of the PCB board. The adjusted distance must be adapted to the size of the PCB board to accommodate PCB boards of different sizes.

[0030] Specifically, when the limiting component is set screw 5, loosen the set screws 5 (8 in total) with an Allen wrench, pull the side plate 1 to the outermost side, and then place the PCB board to be stored into a symmetrical set of guide grooves 7 in the same cavity. Slowly push the side plate 1 inward. When the distance from the side plate 1 to one end of the PCB board is equal to the distance from the other end of the PCB board to the center plate 6 and is 1.5mm, stop pushing the side plate 1 and tighten the set screws 5 with an Allen wrench. Then take out the PCB board. At this time, one cavity of the multi-functional PCB board frame is adjusted. There is a 1.5mm gap between the two ends of the PCB board and the guide groove 7 to facilitate the entry and exit of the PCB board, while preventing the PCB board from being stressed in the frame. Therefore, the depth of the guide groove 7 should be greater than 1.5mm. The adjustment method of the other cavity of the multi-functional PCB board frame is the same as above.

[0031] Meanwhile, the distance between side plate 1 and center plate 6 can also be adjusted using fixtures. Based on the required size of the PCB board to be stored, make two PCB boards as fixtures. The thickness of the fixtures is the same as that of the PCB board, and the width is 3mm greater than the width of the PCB board. Loosen the set screw 5 with an Allen wrench, pull side plate 1 to the outermost side, and then insert the fixtures into the guide grooves 7 at both ends on the same side. Slowly push side plate 1 inward. When side plate 1 and center plate 6 clamp the fixtures, stop pushing side plate 1 and tighten the set screw 5 with an Allen wrench. Take out the fixtures at both ends. At this time, the adjustment of one cavity of the multi-functional PCB board frame is completed. The adjustment method of the other cavity of the multi-functional PCB board frame is the same as above.

[0032] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
