These problems affect the processing efficiency of the device. Moreover, the common double-sided grinding structure is not easy to flexibly adjust the template roller spacing according to the thickness of the circuit board product, which leads to poor processing effect and can no longer meet people's needs. For this reason, we propose a new type of printed circuit board grinding machine with automatic loading and unloading and grinding to solve the above-mentioned defects. Utility Model Content
