Description

Technical Field

[0001] The utility model relates to a transfer device for laser cutting, belonging to the technical field of laser cutting transfer. Background Art

[0002] In the process of sheet metal processing, the sheet metal needs to be cut first. The commonly used cutting equipment is a laser cutting machine. The laser cutting machine is a device that uses a high-power laser beam to irradiate the surface of the workpiece to make the workpiece reach the melting point or boiling point, and then uses high-pressure gas to blow away the melted or vaporized metal.

[0003] After the sheet metal is horizontally processed on the laser cutting machine, it is generally horizontally unloaded and stacked horizontally together. However, in actual applications, after the sheet metal is horizontally processed, processes such as painting and powder spraying are required. In the painting process, the sheet metal is generally vertically lifted and hoisted into the painting room. In this case, the sheet metal unloaded by the existing laser cutting transfer mechanism needs to be manually erected before it can be hoisted, and the operation is extremely inconvenient.

[0004] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to be improved. Content of the Utility Model

[0005] Aiming at the deficiencies in the background art, the utility model provides a transfer device for laser cutting, which can transfer the sheet metal from the laser cutting machine to the hoisting station with high efficiency, and can control the unloading angle of the sheet metal to meet the hoisting at the hoisting station and better adapt to the automated production line.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A transfer device for laser cutting, including a support base arranged on one side of the laser cutting machine. An installation vertical plate is vertically installed on the support base. A main shaft is fixedly installed on one side of the installation vertical plate. A swing arm is rotatably installed on the main shaft. A first synchronous pulley is fixedly installed on the main shaft. When the swing arm swings around the main shaft, the first synchronous pulley does not rotate with it.

[0008] A second synchronous pulley is rotatably installed at the upper end of the swing arm. The first synchronous pulley and the second synchronous pulley are driven by a synchronous belt. A sheet metal grabbing device is fixedly installed on the second synchronous pulley. The swing arm is driven by a swing arm driving device.

[0009] Further, the sheet metal grabbing device includes an adapter plate and a suction cup. The adapter plate is fixedly connected to the second synchronous pulley and rotates with the second synchronous pulley. The suction cup is installed on the adapter plate.

[0010] Further, the sheet material grasping device further includes a fixing plate, on which a plurality of lengthening rods perpendicular to it are uniformly arranged, and suction cups are installed at the lower ends of the lengthening rods.

[0011] Further, the swing arm driving device includes a stepping motor, which drives the swing arm to swing through a push-pull rod and a rocker arm rod. One end of the rocker arm rod is fixedly connected to the rotating shaft of the stepping motor, the other end of the rocker arm rod is hinged to one end of the push-pull rod, and the other end of the push-pull rod is hinged to the swing arm.

[0012] Further, the length of the push-pull rod is adjustable, and the push-pull rod is hinged at a position below the middle of the swing arm.

[0013] Further, the push-pull rod is provided in two sections, the two sections are connected to each other by threads and fixed and locked by nuts.

[0014] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0015] The lower end of the swing arm is rotatably installed on the installation vertical plate. One side of the installation vertical plate is fixedly installed with a main shaft. The swing arm is rotatably installed on the main shaft. A first synchronous pulley is fixedly installed on the main shaft.

An installation vertical plate 3 is vertically installed on the support base 2. A main shaft is fixedly installed on one side of the installation vertical plate 3. A swing arm 4 is rotatably installed on the main shaft. A first synchronous belt pulley 5 is fixedly installed on the main shaft. When the swing arm 4 swings around the main shaft, the first synchronous belt pulley 5 does not rotate with it;

[0023] A second synchronous belt pulley 6 is rotatably installed at the upper end of the swing arm 4. The first synchronous belt pulley 5 and the second synchronous belt pulley 6 are driven by a synchronous belt. A sheet material grasping device is fixedly installed on the second synchronous belt pulley 6; the swing arm 4 is driven by a swing arm driving device.

[0024] The sheet material grasping device includes an adapter plate 10 and a suction cup 12. The adapter plate 10 is fixedly connected to the second synchronous belt pulley 6 and rotates together with the second synchronous belt pulley 6. The suction cup 12 is installed on the adapter plate 10.

[0025] Further, the sheet material grasping device further includes a fixing plate 11. A plurality of extension rods 13 perpendicular to the fixing plate 11 are uniformly arranged on the fixing plate 11. The suction cup 12 is installed at the lower end of the extension rod 13.

[0026] The swing arm driving device includes a stepping motor 9. The stepping motor 9 drives the swing arm 4 to swing through a push-pull rod 7 and a rocker arm rod 8. One end of the rocker arm rod 8 is fixedly connected to the rotating shaft of the stepping motor 9. The other end of the rocker arm rod 8 is hinged to one end of the push-pull rod 7. The other end of the push-pull rod 7 is hinged on the swing arm 4.

[0027] Further, the length of the push-pull rod 7 is adjustable, and the push-pull rod 7 is hinged at a position below the middle of the swing arm 4. Adjusting the length of the push-pull rod 7 can adjust the swing range of the swing arm 4.

[0028] The push-pull rod 7 is provided in two sections. The two sections are connected to each other by threads and are fixed and locked by nuts.

[0029] The specific working principle of the present utility model:

[0030] The lower end of the swing arm 4 is rotatably installed on the installation vertical plate 3. One side of the installation vertical plate 3 is fixedly installed with a main shaft. The swing arm 4 is rotatably installed on the main shaft. A first synchronous pulley 5 is fixedly installed on the main shaft. The upper end of the swing arm 4 is rotatably installed with a second synchronous pulley 6. A sheet material gripping device is fixedly installed on the second synchronous pulley 6. When the swing arm driving device drives the swing arm 4 to swing, the first synchronous pulley 5 does not rotate with it. The first synchronous pulley 5 and the second synchronous pulley 6 are driven by a synchronous belt. When the swing arm 4 swings, the second synchronous pulley 6 can be pulled to rotate through the synchronous belt. Adjusting the relative sizes of the first synchronous pulley 5 and the second synchronous pulley 6 can adjust the rotation angle of the second synchronous pulley 6. On the premise that the swing arm 4 swings by the same angle, the larger the diameter of the first synchronous pulley 5 relative to the second synchronous pulley 6, the larger the rotation angle of the second synchronous pulley 6. Thus, the angle after the sheet material is unloaded can be flexibly adjusted to meet the hoisting at the hoisting station and better adapt to the automated production line.

[0031] The swing arm driving device includes a stepping motor 9, a push-pull rod 7 and a rocker arm 8. When the stepping motor 9 drives the rocker arm 8 to rotate, the push-pull rod 7 is pulled to drive the swing arm 4 to swing.
