Problems solved by technology

Before the PCB board is cut, several PCB boards of the same size are usually inserted into the board frame for storage. There are generally several vertical slots arranged side by side in the board frame, and the length of the slot is generally roughly equal to the length of the PCB board. , but the width of the slot is usually greater than the thickness of the PCB board, so the PCB board will be slightly inclined in the slot, and the inclination angle of each PCB board is not necessarily the same, so it is difficult to adjust the height of the edge of each PCB board in the board frame. accurately determine
Since the circuit is printed on the PCB board, only the blank area at the edge can be grasped by the mechanical gripper of the board removal device, and the blank area at the edge of the board is generally narrow. If the clamping depth is too deep, it may exceed The blank area will damage the circuit structure on the board. If the clamping is too shallow, it may not be securely clamped. Therefore, if the height of the upper edge of the PCB cannot be accurately determined, it will not be possible to use the board removal device to remove it from the board frame. The PCB board is taken out and placed on the board position of the printed circuit board processing equipment for processing. Therefore, at present, in this field, the PCB board can only be taken out of the board frame by manual operation and placed on the board position. Time-consuming, labor-intensive, low-efficiency, and low-precision placement
Moreover, due to the large size and thin thickness of the PCB board, it is easy to cause the board to bend or warp due to its own gravity when the board is moved and turned over, resulting in damage to the board

Abstract

The invention relates to the technical field of printed circuit board processing equipment, in particular to a board taking device and a board taking method. The board taking device comprises a boardframe transferring mechanism, a board lifting mechanism, a board placing mechanism, a laser photoelectric sensor and a control device, wherein the laser photoelectric sensor comprises a laser emitterand a laser receiver, the laser emitter is fixedly arranged on the front side of a board piece and lower than the upper edge of the board piece, the laser receiver is fixedly arranged on the rear sideof the board piece and higher than the upper edge of the board, the laser emitter faces the laser receiver, and the control device is connected with the board frame transferring mechanism, the boardlifting mechanism, the board placing mechanism and the laser photoelectric sensor. By adopting the board taking device, the height of the upper edge of a to-be-taken board piece can be accurately measured, then the board piece is automatically moved to a designated board placing position through cooperation of the board lifting mechanism and the board placing mechanism, thus high efficiency, convenience and high precision are achieved, stress balance of the board piece can be kept in the board moving and overturning process, and bending or buckling deformation of the plane of the board piece is avoided.

Description

technical field [0001] The invention relates to the technical field of printed circuit board processing equipment, in particular to a board taking device and a board taking method. Background technique [0002] At present, printed circuit boards (PCB boards) are usually large square boards during processing and production, and are cut into several smaller-sized finished boards in the later stage of production. Before the PCB board is cut, several PCB boards of the same size are usually inserted into the board frame for storage. There are generally several vertical slots arranged side by side in the board frame, and the length of the slot is generally roughly equal to the length of the PCB board. , but the width of the slot is usually greater than the thickness of the PCB board, so the PCB board will be slightly inclined in the slot, and the inclination angle of each PCB board is not necessarily the same, so it is difficult to adjust the height of the edge of each PCB board i...
