Description

Technical Field

[0001] The utility model belongs to the technical field of PCB circuit board processing, and particularly relates to a PCB circuit board splitting machine. Background Art

[0002] A PCB circuit board splitting machine is specialized for cutting, dividing, and slitting various PCB circuit boards in the electronic production industry. During the production process of PCB boards, in order to improve production efficiency, multiple small circuit boards are usually fabricated on the same large board, i.e., a panel. After all processes are completed, these small circuit boards are then cut and separated from the panel for subsequent assembly and testing.

[0003] When the existing PCB circuit board splitting machine moves, it drives the moving mechanism by the intermittent start of the motor, pushing the PCB circuit board to move different distances. This method has the following drawbacks: (1) The intermittent start of the motor will cause the speed of the PCB circuit board to be uneven during movement. The intermittent start mode of the motor may result in insufficient positioning accuracy of the PCB circuit board during movement. Due to the time delay and inertia during the start and stop of the motor, it may cause slight deviations in the position of the circuit board during movement, affecting the subsequent cutting accuracy; (2) The frequent start and stop of the motor will consume more electrical energy, resulting in an increase in the energy consumption of the entire splitting machine; (3) The intermittent start of the motor will exacerbate the wear of mechanical components, especially components such as the motor and transmission shaft. In the long run, it may lead to an increase in equipment failure rate and shorten the service life of the equipment; (4) The frequent start and stop of the motor may also generate relatively large noise and vibration, which have an adverse impact on the operating environment and operators.
