Problems solved by technology
However, the upper plate frame matched with the existing vertical electrode type plasma etching machine is only suitable for processing circuit boards with a fixed thickness. When the thickness of the circuit board changes, the upper plate frame must be replaced to clamp. The board frame is only suitable for clamping thicker and higher hardness circuit boards, and it cannot be clamped and fixed for thin and soft circuit boards

Embodiment Construction
[0017] Based on the existing upper plate frame of the plasma etching machine can only clamp and fix the circuit board of a certain thickness, when the thickness of the circuit board changes, the upper plate frame must be replaced, and the existing upper plate frame cannot clamp and fix the thin plate Or the defect of the soft board, the embodiment of the present invention improves the original upper board frame, and provides a board guide rail and a splint tool, which can clamp and fix the circuit board of any thickness. Wherein, the plate guide rail includes: a connecting rod, a pressing plate, a suspension beam, and a pressing device. The pressing plate can be movably fixed on the connecting rod between the side walls of the guide rail through the suspension beam. The pressing plate applies pressure so that the circuit board placed between the pressing plate and the other side wall can be compressed. By adopting the board guide rail of the embodiment of the present invention...

The invention relates to the field of manufacturing of circuit boards and particularly discloses a circuit board guide rail and a circuit board clamping tool. The circuit board clamping tool is capable of fixedly clamping circuit boards with any thickness. The circuit board guide rail comprises a first side wall 11, a second side wall 12, a middle connection portion 13, at least one connecting rod 3, a press plate 4, at least one suspension beam 5 and a press device 7, a first groove and a second groove are limited by the first side wall 11, the second side wall 12 and the middle connection portion 13, the middle connection portion 13 is provided with at least one through hole 6, two ends of each connecting rod are fixed on the first side wall 11 and the second side wall 12 respectively in the first groove, one end of each suspension beam 5 is fixedly connected on one side of the press plate 4 while the other end thereof penetrates into one through hole 6 and is movably connected with the connecting rod 3, and the press device 7 is fixed on the part of the first side wall 11 limited in the second groove and used for applying force on the press plate 4 and pressing the circuit boards between the press plate 4 and the part of the second side wall limited in the second groove.
Description
technical field [0001] The invention relates to the field of circuit board production, in particular to a board guide rail and a splint manufacturing tool. Background technique [0002] Many processes in the circuit board manufacturing process require the use of plasma etching equipment and the matching upper board frame. When in use, the upper board frame needs to be used to fix and clamp the circuit board, and the plasma etching equipment is used for processing. like figure 1 As shown, it is a structural diagram of the existing upper plate frame, including: the upper plate clamping guide rail 11, the lower plate clamping guide rail 12, and the support frame 13, the upper plate clamping guide rail 11 and the lower plate clamping guide rail 12 are respectively fixed At both ends of the support frame 13, the slots of the upper board clamping guide rail 11 and the lower board clamping guide rail 12 correspond to each other, and are used to clamp the circuit board in the slots...
