Problems solved by technology
[0006] The object of the present invention is to provide a kind of auxiliary equipment for PCB board clamping for electrical professional practice courses, to solve the prior art proposed in the above-mentioned background technology, in order to improve the process quality of the circuit board for drilling, printing and etching, etc., usually The auxiliary equipment for PCB board clamping is used. The existing auxiliary equipment for PCB board clamping still has some shortcomings in use. The general auxiliary equipment for board clamping is difficult to apply to the positioning of ordinary circuit boards and flexible circuit boards at the same time. Clamping work, and the effect is poor, especially for ordinary circuit boards, due to the different processing positions, the circuit board is often damaged due to excessive clamping force

The invention discloses PCB clamping auxiliary equipment for an electrical professional practice class and belongs to the technical field of circuit board processing. The equipment comprises a workbench, the workbench is provided with a clamping assembly, and a driving assembly is disposed between the clamping assembly and the workbench. Through the designed clamping assembly and the designed driving assembly, a first auxiliary clamping bottom plate and a second auxiliary clamping bottom plate move in the directions away from each other, so that a circuit board can be fixed, subsequent spraying work is facilitated. The PCB clamping auxiliary equipment can be suitable for clamping and positioning work of a common circuit board and a flexible circuit board at the same time, does not cover the spraying face of the circuit board, can support multiple faces of the circuit board, is high in stability and precision, can quickly relieve the clamping effect on the circuit board just by controlling a negative pressure drainage pump to stop working when relieving force attached to the circuit board, effectively improves the machining quality and efficiency of the circuit board, greatly improves the practicability and can meet the requirements of users.
Description
technical field [0001] The invention relates to the technical field of circuit board processing, in particular to auxiliary equipment for clamping PCB boards used in electrical professional practice courses. Background technique [0002] The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. [0003] Some invention patents in the field of circuit board processing technology are disclosed in the prior art, among which the invention patent with the application number CN110691468B discloses a jig tooling for circuit board drilling. The technical problem solved by this patent is in the circuit board In the drilling process, the circuit board first needs to be placed on the designated position where the board is placed, and then the four corners of the circuit board are fixed with spring clamps. Because the four corners need to be fixed separately, the fix...
