Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a suction cup device for automatic sorting of laser-cut parts. Background Technology

[0002] Vacuum suction cups, also known as vacuum grippers, are actuators in vacuum equipment. Generally, using vacuum suction cups to grasp products is the most cost-effective method. Vacuum suction cups come in various types. Rubber suction cups can operate at high temperatures, while silicone rubber suction cups are well-suited for gripping products with rough surfaces; polyurethane suction cups are very durable. Furthermore, in actual production, if oil resistance is required, suction cups made of polyurethane, nitrile rubber, or vinyl-containing polymers can be considered. Typically, to avoid scratching the surface of the product, it is best to choose suction cups with corrugated tubing made of nitrile rubber or silicone rubber. Nitrile rubber, with its high tensile strength, is widely used in various vacuum gripping equipment.

[0003] Vacuum chucks are widely used in laser cutting technology, primarily for automated workpiece sorting. Typically, multiple chucks are needed simultaneously to adhere to the workpiece surface. In existing vacuum chuck devices, multiple chucks are positioned on the same horizontal plane, and their vertical positions cannot be adjusted individually. Therefore, they are generally only used for adsorbing flat workpieces. For workpieces with irregular surfaces, the vertical position of the vacuum chucks needs to be adjusted to achieve the desired adsorption; otherwise, adsorption will not be possible.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figures 1 to 3 This embodiment provides a suction cup device for automatic sorting of laser-cut parts, including a first mounting plate 1, a vacuum suction cup 2, and a fastening block 3.

[0021] The first mounting plate 1 has multiple mounting holes 1a for mounting vacuum suction cups 2.

[0022] The vacuum suction cup 2 includes a suction cup part 2a and a connecting part 3b that are connected to each other, and multiple vacuum suction cups 2 are disposed in multiple mounting holes 1a.

[0023] The fastening block 3 is semi-cylindrical, and two fastening blocks 3 form a set corresponding to one vacuum suction cup 2. The two fastening blocks 3 are arranged around the outside of the connecting part 3b. Pipe threads are formed on the outside of the fastening block 3 and the inside of the mounting hole 1a so that each set of fastening blocks 3 is threadedly connected to a mounting hole 1a. Specifically, the fastening block 3 includes a screwing part 3a and a connecting part 3b that are fixedly connected to each other. Both the screwing part 3a and the connecting part 3b are semi-cylindrical. The connecting part 3b is generally cylindrical and has a certain length so that it can be clamped by the fastening block 3 when it moves within a certain height range. The outer diameter of the screwing part 3a is larger than the outer diameter of the connecting part 3b, and pipe threads are formed on the outside of the connecting part 3b. The fastening block 3 is connected to the first mounting plate 1 by a pipe thread. When the two fastening blocks 3 are screwed, their distance will decrease, so the two fastening blocks 3 will clamp the connecting part 3b, thereby fixing the vacuum suction cup 2. When it is necessary to adjust the height of the vacuum suction cup 2, the fastening blocks 3 can be loosened to adjust the position of the vacuum suction cup 2 up and down.

[0024] Preferably, the suction cup device for automatic sorting of laser-cut parts further includes multiple elastic connecting sleeves 4. Each elastic connecting sleeve 4 is cylindrical, and each elastic connecting sleeve 4 corresponds to a set of fastening blocks 3. The elastic connecting sleeve 4 is sandwiched between the fastening blocks 3 and the connecting portion 3b. The elastic connecting sleeve 4 deforms under pressure, increasing the contact area with the connecting portion 3b and thus increasing friction. Furthermore, each elastic connecting sleeve 4 is fixedly connected to two fastening blocks 3, preventing the fastening blocks 3 from being lost.

[0025] Preferably, the suction cup device for automatic sorting of laser-cut parts further includes a connecting air pipe 5 and an air pipe connector 6. One end of the connecting air pipe 5 is connected to the vacuum suction cup 2, and the other end is connected to the air pipe connector 6. The connecting air pipe 5 is generally made of a soft material because the vacuum suction cup 2 needs to be adjusted up and down, so the connecting air pipe 5 needs to have a certain degree of mobility. More preferably, the suction cup device for automatic sorting of laser-cut parts further includes a first flange 7 and a second flange 8. The other end of the connecting air pipe 5 away from the vacuum suction cup 2 is connected to the first flange 7. Here, an integral connection or a connector can be used. The air pipe connector 6 is connected to the second flange 8. Here, an integral connection or a connector can be used. A magnetic connector is provided between the first flange 7 and the second flange 8 to connect the first flange 7 and the second flange 8. The first flange 7 and the second flange 8 can be made of a soft material. When the magnetic connector attracts the first flange 7 and the second flange 8, there will be a certain deformation, thereby reducing the gap between the first flange 7 and the second flange 8 and enhancing the airtightness. Specifically, both the first flange 7 and the second flange 8 are embedded with magnetic rings 9. The two magnetic rings 9 attract each other, thereby bringing the first flange 7 and the second flange 8 closer together. This makes it easier and faster to disassemble and connect the connecting air tube 5 when replacing the vacuum suction cup 2.

[0026] Preferably, the suction cup device for automatic sorting of laser-cut parts further includes a second mounting plate 10, and an air pipe connector 6 is fixedly connected to the second mounting plate 10. Generally, the air pipe connector 6 can be installed on the second mounting plate 10 using a nut. More preferably, the suction cup device for automatic sorting of laser-cut parts further includes connecting posts 11. Multiple connecting posts 11 are disposed between the first mounting plate 1 and the second mounting plate 10. One end of the connecting post 11 is threadedly connected to the first mounting plate 1, and the other end is fixedly connected to the second mounting plate 10 with a bolt.

[0027] In summary, this utility model provides a suction cup device for automatic sorting of laser-cut parts. The fastening block and the first mounting plate are connected by a pipe thread. When the fastening block rotates towards the first mounting plate, the distance between the two fastening blocks decreases, thereby clamping the vacuum suction cup. Therefore, the height of the vacuum suction cup can be easily adjusted, and multiple vacuum suction cups can be adjusted one by one without affecting each other. Thus, it is suitable for workpieces of different shapes and irregular surfaces.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
