Description

Accurate counterpoint mechanism

Technical Field

The utility model relates to the technical field of circuit board hole plugging, in particular to an accurate alignment mechanism.

Background

In the conventional circuit board processing process, the steps of plugging holes, scraping ink, inserting frames and the like need manual work to transfer the circuit board. First, in order to perform the hole plugging operation, a worker must remove the circuit board from the storage table and place it into the hole plugging machine. In the hole plugging machine, a circuit board is clamped for a hole plugging operation. Then, the worker needs to take out and place the circuit board again into the ink scraping machine to perform the ink scraping operation. Finally, the circuit board is picked up again and placed into the rack inserting machine for the next operation.

These steps require manual work to accomplish, which means inefficiency, as one would experience various problems in operation. For example, workers may misplace circuit boards due to their fatigue or other factors, resulting in inaccurate placement. This may result in damage or poor quality of the circuit board in subsequent steps. Further, due to the limitation of manual operation, the production speed may be limited because it is necessary to wait for the worker to finish one step before proceeding to the next step.

Furthermore, manual operations may lead to undesirable results, for example, if a worker has a problem in a certain link, the efficiency of the overall process may be affected. These problems may result in the worker spending more time and effort to repair the errors, which may result in an increase in the overall cost of the circuit board manufacturing process.

Overall, these steps in the conventional circuit board manufacturing process require manual handling of the circuit board, which can lead to inefficiency and poor accuracy problems. If these steps can be improved and the degree of manual intervention reduced, the efficiency and accuracy of circuit board manufacture can be improved.
