Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB processing, in particular to an automatic feeding type automatic cutting plate machine. BACKGROUND

[0002] The commonly used circuit board dividing machine mainly includes a milling cutter type dividing machine and a hobbing cutter group type dividing machine. The hobbing cutter group type dividing machine is mainly used for strip-shaped or straight-line cutting, and the milling cutter type dividing machine is mainly used for curved edge forming cutting. The existing circuit board dividing machine still has some deficiencies.

[0003] In the prior art, for example, a circuit board dividing machine and method disclosed in CN0000828A, the dividing machine includes a machine frame and a feeding device, a moving device, a supporting conveying device, a cutting device and a discharging device which are all arranged on the machine frame. The feeding device is used to convey the circuit board to be processed, and the moving device is used to transport the circuit board to be processed to the supporting conveying device. The supporting conveying device is arranged on the side of the feeding device and is used to convey and position the circuit board to be processed to the cutting device. The cutting device includes a hobbing cutter group which is located on the side of the supporting conveying device away from the feeding device and cuts the circuit board to be processed along the length direction of the feeding device. The discharging device is arranged on the side of the cutting device away from the feeding device to output the processed circuit board. The advantage is that it realizes full automation of cutting and improves production efficiency. However, in the specific use process, it cannot automatically clean the plate parts, so that the dust after cutting is easily attached to the outside of the plate parts, thereby affecting the normal use of the subsequent process.

[0004] For example, a circuit board dividing machine with multi-axis moving function for printed circuit board processing disclosed in CN115971956B, by setting dust suction barriers one and two and a dust suction pipe, the dust suction range during the dividing operation is effectively guaranteed. The semi-enclosed dust suction design does not cause damage to the milling cutter body. The setting of maintenance notches one and two facilitates the maintenance and replacement of the milling cutter body. At the same time, the dust suction barriers one and two and the dust suction pipe can be directionally switched along with the change of the moving direction of the milling cutter body, further ensuring the dust suction efficiency. However, it is inconvenient to automatically feed the workpiece during use, so manual placement and position adjustment of the plate parts are required, which reduces the production efficiency and cannot ensure the dividing precision.

[0005] Another example is an automatic circuit board cutting machine with publication number CN112497288A, which includes a feeding device, a loading device, a supporting device, a first cutting device, a conveyor belt, a positioning device, a second cutting device and a collection box. The feeding device is vertically arranged on the ground, the loading device is arranged beside the feeding device and connected to one end of the feeding device, the supporting device is arranged beside the feeding device, the first cutting device is arranged on the supporting device, the first cutting device cooperates with the supporting device, the conveyor belt is arranged beside the supporting device, a plurality of steel plates are arranged on the conveyor belt, the positioning device is arranged on the conveyor belt, the second cutting device is fixedly arranged on the conveyor belt, and the collection box is arranged at the discharge end of the conveyor belt. By providing an automatic circuit board cutting machine, the cutting efficiency of the device is improved, and at the same time, mixing of materials during the cutting process is avoided. During use, a horizontal conveyor belt structure is used to realize loading, which makes the overall volume of the equipment larger, and the conveyor belt cannot limit the plate during the feeding process, and cannot ensure the subsequent cutting accuracy, and there are certain defects in use.
