Laser processing equipment and laser processing equipment circuits

Abstract

The invention provides a laser processing equipment circuit. The laser processing equipment circuit comprises an adsorption control loop. The adsorption control loop comprises a vacuum pumping loop used for controlling vacuum pumping, a suspension loop used for controlling vacuum pumping to stop and a vacuum breaking loop used for breaking vacuum. A vacuum pumping intermediate relay and a first vacuum pumping normally-open contact corresponding to the vacuum pumping intermediate relay are arranged on the vacuum pumping loop. The two ends of the first vacuum pumping normally-open contact are connected with a first foot switch in parallel. A second vacuum pumping normally-open contact corresponding to the vacuum pumping intermediate relay is arranged on a loop where a vacuum pumping draught fan power socket is located. An on-off control contact is also arranged on the vacuum pumping loop. By adopting the design, an operator just needs to pedal the first foot switch, so that the vacuum pumping loop is closed, a self-locking structure is formed, the first foot switch does not need to be pedaled artificially all the time, and consequently the laser processing equipment circuit which enables workpiece fixing operation to be easier and more convenient is realized. The invention further provides laser processing equipment including the laser processing equipment circuit.

Description

technical field [0001] The present application relates to the technical field of laser processing equipment, and more specifically, relates to a laser processing equipment circuit. The present application also relates to a laser processing device comprising the above laser processing device circuit. Background technique [0002] In the production process of laser processing equipment, in order to pursue a smooth cutting end surface, it is often necessary to blow auxiliary gas coaxially with the laser, and when cutting a product with a thickness of less than 1mm, in order to make the product adsorb on the work surface, the work platform needs to be evacuated. The product is stably adsorbed on the platform so that the product cannot be easily moved or warped. Furthermore, when the cutting process produces odorous and toxic fumes, these fumes need to be discharged from the workshop to avoid harming the staff. [0003] In the prior art, there is no laser processing equipment th...

Problems solved by technology

[0003] In the prior art, there is no laser processing equipment that can realize the above three functions at the same time. In particular, there is no laser processing equipment that can realize the auxiliary gas blowing and adsorption positioning at the same time in the prior art. The core problem is that the current The performance of the control circuit in the existing technology is insufficient, and it is impossible to realize simultaneous control

[0004] The more important problem is that the circuit used to control vacuuming in the prior art cannot realize self-locking, which makes the operation of vacuuming difficult, requiring people to step on the pedal to control the vacuuming all the time to fix the workpiece
