Blanking and pick-up device for laser cutting machine

Abstract

The invention discloses a blanking and pick-up device for a laser cutting machine. The blanking and pick-up device comprises a fixed support. A first air cylinder is arranged on the fixed support. An upper support is connected to a first piston rod of the first air cylinder. A lower support is connected to the upper support. A second air cylinder is connected to the lower support. A male die plate is connected to a second piston rod of the second air cylinder. Electromagnets are arranged on the male die plate. A female die plate is connected with the bottom end of the lower support. The blanking and pick-up device is simple in structure, easy to operate and low in input cost; production efficiency is improved, manpower is reduced, work intensity is reduced, and hidden danger of quality is eliminated; the occupied space is small; and operation is basically carried out on an original interactive work table board of the laser cutting machine.

Description

technical field [0001] The invention relates to the field of laser cutting machines, in particular to a material unloading and pick-up device for a laser cutting machine. Background technique [0002] As laser processing technology is more and more recognized and adopted in the field of metal processing, laser (Laser) cutting machines are widely used in sheet metal processing companies for plane processing of thin plates. But generally there are the following problems: 1. After cutting in a specific direction, the parts cannot be placed on the two support points of the shelf, and will fall off and fall into the waste bin. Manual arrangement is laborious and time-consuming. 2. Engineers often leave three connection points in different directions during cutting programming. Generally, the width of the connection point is less than 0.2mm without cutting to avoid parts falling, which increases the difficulty of picking up parts. Use a flat-head screwdriver or other sharp tools ...

Problems solved by technology

But there are generally the following problems: 1. After cutting in a specific direction, the parts cannot be placed on the two support points of the shelf, and they will fall off and fall into the waste bin. Manual sorting is laborious and time consuming

2. Engineers often leave three connection points in different directions during cutting programming. Generally, the width of the connection point is less than 0.2mm without cutting to avoid parts falling, which increases the difficulty of picking up parts. Use a flat-head screwdriver or other sharp tools to break the connection point, and take each part of no less than 607 pieces. The time is long and the efficiency is low. Often, the speed of picking up parts is too slow to affect subsequent loading.

3. There are quality risks. Due to the large number of small parts, parts with the same shape on the front and back often appear in manual pick-up, which are not stacked on the same processing surface, leaving quality risks for subsequent processing. Subsequent bending personnel do not pay attention, and may It will cause reverse bending, resulting in poor quality or even scrapped parts

4. Some equipment also adopts an automatic unloading system, but after the laser cutting of the parts is completed, the processing is suspended, and the cutting head of the laser machine is moved to a specific position to prevent the suction cup or clamp that grabs the material from hitting the cutting head, and the processing is suspended. The efficiency of laser cutting is reduced. Even so, parts with a length and width of less than 70mm cannot be picked up. They are also transferred to the waste bin or left with connection points for manual pick-up.
