Description

Technical Field

[0001] This utility model relates to the field of PCB processing equipment technology, and in particular to a PCB transfer mechanism with board drop monitoring function. Background Technology

[0002] The PCB manufacturing process involves numerous steps, including lamination, exposure, and development. During these processes, PCBs need to be transferred between different workstations. Existing PCB transfer mechanisms are prone to issues such as fluctuations in the vacuum level of the customer's air source, the number of holes on the board, the board weight, and inaccurate board dimensions. These factors can easily cause boards to fall off during transfer, leading to equipment jams and disrupting normal production. Summary of the Invention

[0003] The problem to be solved by this utility model is to provide a PCB transfer mechanism with board drop detection function, which can monitor whether a board drops during the transfer process and avoid board drop causing machine jamming.

[0004] To solve the above technical problems, a PCB transfer mechanism with board drop monitoring function provided by this utility model is provided. The mechanism includes an X-axis connecting beam and two opposing clamping arm mechanisms. The clamping arm mechanisms include a Y-axis mounting beam that is slidably connected to the X-axis connecting beam along the X-axis direction, an X-axis linear drive device that is set on the X-axis connecting beam and drivenly connected to the Y-axis mounting beam, and a number of positioning devices distributed on the Y-axis mounting beam. The positioning devices are used to position the PCB. A number of board drop monitoring photoelectric switches are distributed on the Y-axis mounting beam.

[0005] Preferably, the positioning device is a suction cup.

[0006] Preferably, the positioning device is an electric gripper or a pneumatic gripper.

[0007] Preferably, the X-axis linear drive device is a linear motor.

[0008] The beneficial effects of this utility model are as follows: This utility model provides a PCB transfer mechanism with a board drop detection function. When the X-axis linear drive device is working, it can drive the Y-axis mounting beam to move left and right, thereby allowing the two Y-axis mounting beams to move closer or further apart, so that the positioning devices on the two Y-axis mounting beams can work together to pick up and place the PCB. When there is a PCB on the transfer mechanism, the board drop detection photoelectric switch can detect that the PCB is in place. When the PCB falls, the corresponding board drop detection photoelectric switch will not detect the PCB. The board drop detection photoelectric switch can send a signal to the control system, so that the control system can promptly determine that there is a PCB drop and notify it, so as to facilitate the removal of the fallen PCB, avoid machine jamming, and ensure stable production.

The positioning devices 22 are used to position the PCB, and a plurality of board drop monitoring photoelectric switches 3 are distributed on the Y-axis mounting beam 20.

[0016] Its working principle is as follows: When the X-axis linear drive device 21 is working, it can drive the Y-axis mounting beam 20 to move left and right, so that the two Y-axis mounting beams 20 move closer or further away, so that the positioning devices 22 on the two Y-axis mounting beams 20 can cooperate to pick up and put down the PCB4. When there is a PCB4 on the transfer mechanism, the drop detection photoelectric switch 3 can detect that the PCB4 is in place. When the PCB4 falls, the drop detection photoelectric switch 3 at the corresponding position will not detect the PCB4. The drop detection photoelectric switch 3 can send a signal to the control system, so that the control system can promptly determine that there is a PCB4 drop and notify it, so that the fallen PCB4 can be picked up, avoiding machine jamming and ensuring stable production.
