Description

A fixture for horizontal copper upper plate of PCB thin plate

technical field

The utility model relates to an auxiliary tool for PCB board production, in particular to a jig for horizontalizing copper upper boards of PCB thin boards.

Background technique

At present, when the thickness of the PCB board is less than 0.2mm, due to the gap between the rollers and the pressure of the potion, board jamming and coiling will occur. To solve this problem, a guide plate can be added in front of the thin board. The current industry practice Tape is used to fix the thin plate on the guide plate, but the tape is easy to fall off and the efficiency is low. The other is to make a PCB thin plate horizontal copper guide jig in advance, see attached drawing 1, including a rectangular flat plate, flat plate One long side of the plate is set as the clamping side, and a plurality of U-shaped splint grooves are arranged side by side along the clamping edge in the flat plate. The splint grooves form a plurality of protrusions on the flat plate. The protruding portion faces the clamping edge, and a splint frame is formed between the protruding portion and the clamping edge, and the PCB board to be guided can be inserted between the protruding portion and the splint frame through the splint groove. Using this jig to guide the thin plate will not cause jamming and curling, but it will be more difficult to fix the thin plate on the jig manually.

Utility model content

In view of the above problems, the utility model provides a PCB sheet level copper upper plate jig, including a rectangular acrylic plate, the acrylic plate is provided with a groove, the groove is parallel to the long side of the acrylic plate, and The slotting direction is inclined towards any long side of the acrylic sheet.

Preferably, the opening width of the groove is 1.5-2.5mm.

Preferably, the grooving direction of the groove forms an angle of 30-60° with the acrylic plate.

Preferably, the depth of the groove is 3-5 mm.

Preferably, the surface of the acrylic plate is pasted with corrugated adhesive tape.

Utilizing the utility model, the splint frame on the PCB thin plate horizontal copper guide fixture can be inserted into the groove and then pressed down toward the direction of the acrylic plate, so that the PCB thin plate horizontal copper guide fixture can be bent, and the protruding part and the splint can be bent. There is a certain angle between the frames, so that the PCB board can be inserted between the protrusion and the splint frame conveniently and quickly.

detailed description

In order to facilitate those skilled in the art to understand the utility model, the utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

As shown in Figure 1, the PCB thin plate horizontal copper guide fixture includes a flat plate 1. The flat plate 1 is a rectangular plate made of a PCB substrate with a thickness of 0.8mm. One long side of the flat plate 1 is set as the clamping side 11, and the flat plate 1 1. A plurality of U-shaped splint grooves 12 are arranged side by side along the clamping edge 11. The width of the splint groove 12 is 1mm. The splint groove 12 forms a plurality of protrusions 13 on the flat plate 1. The U-shaped opening of the splint groove 12 faces the flat plate. 1 Inside, the protruding part 13 faces the clamping side 11, and a splint frame 14 is formed between the protruding part 13 and the clamping side 11, and the PCB board to be guided can be inserted between the protruding part 13 and the splint frame 14 through the splint groove 12 , the protruding part 13 and the clamping plate frame 14 clamp the PCB board to be guided.

In actual use, it is difficult to insert the PCB board to be guided between the protruding part 13 and the splint frame 14, so you can use the horizontal copper upper board fixture for the PCB thin board as shown in Figures 2 and 3, including a rectangular acrylic Plate 2, the acrylic plate 2 is provided with a groove 21 parallel to the long side, the slotting direction of the groove 21 is inclined towards the long side of the upper end of the acrylic plate 2, and forms an angle of 45° with the acrylic plate. The opening width of the groove 21 is 1.5 mm, which is greater than the thickness of the horizontal copper guide fixture of the PCB sheet, so as to facilitate its insertion. The depth of the groove 21 should be smaller than the distance from the splint groove 12 to the clamping edge 11, and should not be too shallow. It can ensure that only the splint frame 14 is inserted in the groove 21 when the PCB thin plate horizontal copper guiding fixture is inserted. In this embodiment, the thickness of the acrylic plate 2 is 5mm, the depth of the groove is 3mm, and the long side of the acrylic plate 2 The length is 10mm larger than the length of the long side of the plate 1 of the horizontal copper guide fixture for the PCB thin plate.

As shown in Figure 4, after the PCB thin plate horizontal copper guide jig is inserted into the groove 21, and then pressed down toward the direction of the acrylic plate 2, the PCB thin plate horizontal copper guide jig can be bent, and the protruding part 13 and the splint There is a certain angle between the frames 14, so that the PCB board can be inserted between the protruding part 13 and the splint frame 14 conveniently and quickly.

In order to prevent damage to the PCB board during operation, the surface of the acrylic board 2 is pasted with wrinkle tape, and the four corners of the acrylic board 2 are rounded.

Although the description of the utility model is performed in conjunction with the above specific embodiments, it is obvious that those skilled in the art can make many substitutions, modifications and changes based on the above contents. Accordingly, all such alternatives, improvements and changes are intended to be included within the scope of the appended claims.
