Collecting mechanism for automotive interior laser cutting and cutting method thereof

Abstract

The invention discloses a collecting mechanism for automotive interior laser cutting. The collecting mechanism comprises a laser device, cutting jigs, a special material taking device and a waste gascollecting device connected with the cutting jigs; the collecting mechanism comprises the two cutting jigs of the left cutting jig and the right cutting jig, namely the left station and the right station, and the cutting jigs are arranged on jig bases 18 through sliding rails 17; and sliding rail motors 16 are arranged on the sliding rails 17, so that the cutting jigs slide on the rails to realizeseamless connection between the jigs and a waste material collecting hopper 1. According to the collecting mechanism for the automotive interior laser cutting, the application of laser cutting in PCand ABS plastic product cutting is achieved, the problem that a plastic product is difficult to cut by laser is solved, and after the process is adopted, a product notch is bright and clean, the slagadhering amount at the bottom is extremely small, and no smoke and dust exist on the surface of the product; a laser hot melting area is obviously reduced, and the amount of cutting smoke and dust isobviously reduced; and the developed jigs are convenient for fixing the product, and improving the precision, so that good product machining precision is obtained, and the error of the product is + / -0.03 mm.

Description

technical field [0001] The invention relates to laser cutting in the field of product processing, in particular to a waste gas collection device for laser cutting of automotive interior trim. Background technique [0002] For the rolling door products of the central control storage box of the car, the single-piece product needs to be painted and then assembled on the flexible base. For example, a single product is directly injected, painted, and then assembled. Due to the low dimensional accuracy of the injection molded product, it cannot meet the product size requirement of + / -0.03mm; moreover, the edge of the product will also have paint overflow after painting, which directly affects the assembly of the product. Therefore, the production method cannot meet the precision and production requirements of the product. The company adopts the overall injection molding of the product, sprays the paint and then cuts the product into individual products for assembly. The main pro...

AI Technical Summary

Problems solved by technology

It is difficult to cut the thicker hot-melt plastic parts by laser. Even if it is cut, the dross of the product is relatively serious, the cut is rough, and the surface of the cut product will leave heavy white smoke and dust, so the product positioning is not accurate. , How to solve the cleanliness, cutting thickness, hanging dross, white smoke, positioning and taking of the target product in laser cutting. The existing technology of laser cutting automotive interior parts has not been truly solved. Existing processes and equipment Can not meet production requirements
