Description

Technical Field

[0001] The utility model relates to the technical field of material sorting, in particular to a sorting device for a laser cutting machine. Background Art

[0002] Laser cutting has received more and more attention in the field of material processing. Laser cutting is a processing method that uses the high energy density of a focused laser beam to achieve sheet cutting. The high-energy-density laser beam causes the sheet to quickly vaporize and evaporate to form holes. As the beam and the material move linearly relative to each other, the holes are continuously formed into very narrow cuts. It has the characteristics of small thermal deformation, neat incisions, and high processing precision. It has a large market demand in many fields such as electrical manufacturing, automobiles, instrument switches, textile machinery, transportation machinery, home appliance manufacturing, elevator equipment manufacturing, and food industry.

[0003] Currently, common laser cutting and sorting equipment has achieved automatic cutting and sorting, such as using robotic arms and suction cups to complete the grabbing, transfer, and discharge of cut materials. However, after laser cutting, the surface of the material will adhere to the dust generated by cutting, and the existing sorting device does not have the ability to clean this dust, so it will increase the time for subsequent material cleaning. Utility Model Content

[0004] The purpose of the present invention is to provide a sorting device for a laser cutting machine to solve the problems raised in the above background technology.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] A sorting device for a laser cutting machine includes a robotic arm, a fixing part, and a driving part. The fixing part includes a suction cup, which is installed at the free end of the robotic arm. A limit frame is provided inside the suction cup, and a pair of air groove groups are provided on the bottom surface of the suction cup. The driving part includes an exhaust part and a collecting part. The exhaust part extracts the air in the suction cup through the air groove group. The air extracted by the exhaust part passes through the collecting part, and the collecting part collects dust in the air extracted by the exhaust part.

[0007] The beneficial effect of adopting the above-mentioned further scheme is that the suction cup is pressed onto the workbench of the laser cutting machine by using a robotic arm and covered on the cut workpiece. At this time, the suction cup is in a sealed state. After the vacuum component is started, the inside of the suction cup can be changed to a negative pressure state. At this time, the workpiece will move upward under the action of air pressure and then be blocked by the limit frame to prevent the workpiece from covering a pair of air groove groups. As the vacuum component continues to work, the dust attached to the workpiece can be sucked into the collecting component, and finally the purpose of completing the cleaning work of the workpiece while adsorbing the workpiece is achieved, thereby reducing the subsequent cleaning time of the workpiece.

[0008] Furthermore, the vacuum component includes a pair of first connecting covers and a Y-shaped tube installed on the back of the suction cup, the pair of first connecting covers respectively cover a pair of the air groove groups, and the two ends of the Y-shaped tube are respectively connected to the pair of first connecting covers. The collecting component includes a collecting frame installed on the side of the suction cup, and the remaining end of the Y-shaped tube is connected to the collecting frame. The top surface of the collecting frame is provided with a through groove. The vacuum component also includes a second connecting cover installed on the top surface of the collecting frame, and the second connecting cover covers the through groove. An vacuum pump is installed on the top surface of the second connecting cover, and a conduit is connected between the input end of the vacuum pump and the second connecting cover.

[0009] Furthermore, the collecting member also includes a filter installed in the through groove.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the vacuum pump discharges the air in the suction cup to the outside through the Y-shaped tube, the collection frame, and the duct. During this process, the dust will also enter the collection frame through the Y-shaped tube, but when entering the duct, it will be blocked by the filter, allowing the collection frame to complete the collection of the dust. At the same time, by using a pair of air groove groups and a larger-sized through groove, the air suction volume of the vacuum pump per unit time can be increased, thereby increasing the adsorption speed of the workpiece and accelerating the collection of dust.

[0011] Furthermore, a magnet is embedded in the inner side of the collection frame, and an iron sheet is embedded in the outer side of the suction cup, and the magnet and the iron sheet are attracted to each other.

[0012] The beneficial effect of adopting the above further solution is that, by using magnets and iron sheets, the collection frame has the ability to be quickly disassembled, and the user can then remove the filter and the second connecting cover to clean the dust in the collection frame.

[0013] Furthermore, a pair of screw holes are provided on the inner side of the suction cup, and a pair of fixing blocks are installed on the side of the limit frame. The top surfaces of the fixing blocks are provided with through holes, and screws are slid into the through holes. The screws are threadedly engaged with the screw holes.

[0014] The beneficial effect of adopting the above further solution is that the limit frame is able to be quickly disassembled by using screws and threaded holes, so that the user can replace the limit frame with one that matches the size of the workpiece so that the limit frame can block the workpiece.

[0015] Furthermore, a sealing frame is installed on the front of the suction cup.

[0016] The beneficial effect of adopting the above further solution is that when the suction cup is pressed against the workbench, the sealing frame can improve the sealing between the suction cup and the workbench.

[0017] Furthermore, an air outlet is provided on the side of the suction cup, and the air outlet is connected to an air outlet pipe via a solenoid valve.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the robotic arm moves according to the pre-input coordinate system, so that the robotic arm can accurately press the suction cup on the workbench and place the workpiece in the suction cup, and at the same time can bring the workpiece to the discharge place. At this time, the solenoid valve opens, the air pump stops working, the air pressure in the suction cup and the external air pressure are balanced, and the workpiece falls to the discharge place.

[0019] Compared with the prior art, the beneficial effect of the present invention is that the laser cutting machine sorting device uses a robotic arm to press the suction cup onto the workbench of the laser cutting machine and covers the cut workpiece. At this time, the suction cup is in a sealed state. After the vacuum pump is started, the inside of the suction cup can be changed to a negative pressure state. At this time, the workpiece will move upward under the action of air pressure and then be blocked by the limit frame to prevent the workpiece from covering a pair of air groove groups. As the vacuum pump continues to work, the dust attached to the workpiece can be sucked into the collection frame, and finally the purpose of completing the cleaning work of the workpiece while adsorbing the workpiece is achieved, thereby reducing the subsequent cleaning time of the workpiece.
