[0002] The boards are flat rectangular building material boards of standard size. According to the length used, the large boards are cut into small boards of the same size. The boards are transported by loading and unloading devices to facilitate processing by the cutting machine.

[0003] A Chinese utility model with authorization announcement number CN217024369U discloses an automatic loading and unloading device for a plate cutting machine. When in use, the device drives two sets of sliders to slide through a lead screw to clamp the plate from the side wall, thereby realizing the loading and unloading operations of the plate. However, in actual use, the device has certain defects. For example, there are certain limitations in clamping the plate through the clamping force. For example, for plates made of materials such as glass plates, excessive mechanical stress is easily generated, which may cause the glass plates to break or be damaged. Therefore, it is necessary to redesign an automatic loading and unloading device for plates to address the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3, an automatic loading and unloading device for plates, comprising a workbench 1, wherein the upper end surface of the workbench 1 is provided with two groups of slide grooves 2, the positions of the two groups of slide grooves 2 are symmetrical to each other, a slide seat 3 is slidably connected in the two groups of slide grooves 2, the slide seat 3 is connected to a fixed seat 5 through a telescopic mechanism, a plurality of groups of device blocks 6 are fixedly connected to the outer wall of the fixed seat 5, an adjusting groove 11 is provided on the outer wall of the plurality of groups of device blocks 6, the device blocks 6 are connected with a slider 7 through a connecting mechanism, the slider 7 is slidably connected in the adjusting groove 11, an electric vacuum suction cup 9 is installed at the lower end of the slider 7, the connecting mechanism comprises a threaded rod 8 rotatably connected to the inner wall of the adjusting groove 11, and the slider 7 is threadedly connected to the threaded section of the threaded rod 8;

[0021] By rotating the threaded rod 8, the slider 7 can be moved along the threaded section of the adjustment groove 11, thereby adjusting the specific position of the electric vacuum suction cup 9 and accurately controlling the contact point between the suction cup and the plate. This effectively enhances the flexibility and operating accuracy of the device, and the threaded connection structure ensures the reliability and stability of the device.

[0022] The telescopic mechanism includes an electric telescopic rod 4 fixedly connected to the upper end surface of the slide 3, the telescopic section of the electric telescopic rod 4 penetrates the slide 3 body and is fixedly connected to the fixed seat 5, the top of the adjusting groove 11 and the upper end surface of the slider 7 are both arranged in a plane, the upper end surface of the slider 7 is in contact with the top of the adjusting groove 11, the angles between the multiple groups of device blocks 6 are consistent, the horizontal height of the electric vacuum suction cup 9 is lower than the height of the fixed seat 5, the side walls of the multiple groups of device blocks 6 are fixedly connected with servo motors 10, and the end of the output shaft of the servo motor 10 is coaxially fixedly connected with the threaded rod 8;

[0023] The upper end surface of the slider 7 contacts the top of the adjusting groove 11. This structural design effectively increases the sliding stability of the slider 7 in the adjusting groove 11 and reduces the jamming phenomenon caused by uneven force on the slider 7. Through the plane contact method, the slider 7 can move more smoothly and stably, improving the overall working efficiency and operation stability of the device.

[0024] In the utility model, during the operation process, the multiple servo motors 10 are first started, and their output shafts drive the threaded rod 8 to rotate, driving the slider 7 to move back and forth along the threaded section of the threaded rod 8 in the adjustment groove 11.

During adsorption, the electric vacuum suction cup 9 starts to generate negative pressure suction, so that the plate is firmly adsorbed on the surface of the electric vacuum suction cup 9, thereby achieving reliable gripping of the plate, and cooperating with the forward and backward sliding of the slide seat 3 to realize the loading and unloading operations of the plate.
