Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB production, in particular to a PCB flattening device. BACKGROUND

[0002] At present, the raw material of the PCB is generally copper plate. In the processing process, the copper plate may be bent, and then needs to be flattened. Under the condition of large elastic-plastic bending, no matter how big the original bending degree of the metal material is, the difference of the residual bending degree after repair will be significantly reduced, and even tends to be consistent. With the reduction of repeated bending degree, the residual bending after elastic recovery will tend to zero value to achieve the purpose of correction.

[0003] In the related art, after the flattening device completes flattening, it needs to receive the PCB through the plate receiving table. When the PCB is stacked to a certain height, the worker needs to take the PCB from the plate receiving table. In this process, the worker needs to wait on the side, wasting time. If the worker leaves temporarily, the PCB cannot be unloaded in time, and the plate receiving table continues to receive the PCB, which makes the PCB on the plate receiving table messy and affects the subsequent unloading, and also causes the PCB to fall and be damaged. CONTENT OF THE INVENTION

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a PCB flattening device, which can not only make the worker use the time efficiently, but also avoid the PCB on the plate receiving table from falling due to stacking too high, so as to cause the plate receiving table to be messy or the PCB to be damaged, ensure the stability and reliability of the work, and improve the product quality.

[0006] The PCB board leveling device according to the embodiments of this application has at least the following beneficial effects: During operation, the feeding mechanism conveys the PCB board onto the conveyor belt; during the conveying process, the PCB board is leveled by the cooperation of the upper and lower pressure rollers at the leveling mechanism; the leveled PCB board is stacked and collected at the end of the conveyor belt; the stacking height of the PCB board on the collection platform is detected by a sensor, and when the stacking height reaches a set value, the sensor sends a signal to the alarm, which is then triggered and sounds an alarm to prompt the operator to remove the board. With the PCB board leveling device described in this application, the operator can handle other tasks while leveling. When the PCB board on the collection platform is stacked to a certain height, the alarm is triggered and sounds an alarm. The operator can then return to remove the board after hearing the alarm, eliminating the need for continuous observation and waiting. This allows for efficient use of time and avoids PCB boards falling from excessively high stacks, preventing clutter or damage to the collection platform, ensuring operational stability and reliability, and improving product quality.
