[0030] See also Figure 1 The embodiment of the present application provides a mechanical claw with adjustable size, including a frame 1, a lifting part 2, a plurality of vacuum suction cups, two mounting bars 4, and a mounting plate 3. The lifting part 2 is arranged on the frame 1; the mounting plate 3 is fixed to the lifting end of the lifting part 2, and the lifting part is provided with two groups of special-shaped grooves 31, each group of special-shaped grooves 31 includes at least two special-shaped grooves 31 parallel to each other; each mounting bar 4 is provided with a slide groove 41, and at least two first sliders are slidably matched in the slide groove 41, and the first slider is connected to the special-shaped groove 31 of the mounting plate 3 through a screw member; the vacuum suction cup is arranged on the slide groove 41 of the mounting bar 4.

[0031] The size-adjustable mechanical claw provided by the embodiment of the utility model, when it is necessary to adsorb materials, only needs to control the mounting plate 3 to descend through the lifting part 2, thereby causing the mounting bar 4 and the vacuum suction cup part to descend, and the vacuum suction cup part adsorbs and picks up the materials, thereby realizing adsorption and picking up of the materials. When it is necessary to adsorb and pick up materials of different sizes, it is only necessary to loosen the threaded member on the first slider, adjust the mounting bar 4 to a suitable angle, and then lock the threaded member to fix the mounting bar 4 (when it is necessary to adsorb small-sized materials, adjust and reduce the distance between the two mounting bars 4, so that the vacuum suction cup part is more concentrated, so as to facilitate adsorption and picking up of small-sized materials. Conversely, adjust and increase the distance between the two mounting bars 4 to adapt to adsorption and picking up of large-sized materials), and then adjust the distribution of the vacuum suction cup part to adapt to adsorption and picking up materials of different sizes. The size-adjustable mechanical claw provided by the embodiment of the utility model has the function of being able to adapt to adsorption and picking up materials of different sizes.

[0032] Specifically, the cross-sectional shape of the slide groove 41 is a structure that is wide at the bottom and narrow at the top. The first slider slides in the slide groove 41. When the threaded member is locked, the first slider is clamped in the slide groove 41 under the upward force given by the threaded member, thereby fixing the mounting bar 4.

[0033] In one embodiment, the vacuum suction cup portion includes a suction cup 54, a mounting block 52, a vacuum tube 53, and a second slider, wherein the second slider is slidably fitted in the slide groove 41 of the mounting bar 4; one end of the mounting block 52 is connected to the second slider by a screw; one end of the vacuum tube 53 is connected to a vacuum pump, and the other end of the vacuum tube 53 is fixed to the mounting block 52; and the suction cup 54 is connected to the end of the vacuum tube 53. By setting the second slider in the slide groove 41 of the mounting block 52, and fixing the mounting block 52 to the second slider by a screw, the second slider can be slidably adjusted in the slide groove 41 by loosening the screw between the two, and then the screw is locked to fix the second slider. In this way, the vacuum suction cup 54 portion can be adjusted in position in the slide groove 41 of the mounting bar 4 according to the size of the material, further improving the applicability of the mechanical claw in this embodiment to adsorb and pick up materials of different sizes.

[0034] In one embodiment, the vacuum tube 53 is a rubber tube. By using the rubber tube as the vacuum tube 53, since the rubber tube is relatively soft, the vacuum tube 53 is not easy to hinder the mechanical claw from sucking the material and is not easy to hinder the mechanical claw from adjusting according to the size of the material.

[0035] In one embodiment, the lifting part 2 includes a cylinder, a cylinder body of the cylinder is fixed on the frame 1 , and a piston rod of the cylinder is connected to the mounting plate 3 .

[0036] In one embodiment, the cylinder is electrically connected to the sensor for sensing the material below, and the sensor controls the extension and retraction of the cylinder. Specifically, the mechanical claw is located above the conveyor belt, and the sensor is on the conveyor belt. When the conveyor belt transports the material (such as LCD or backlight panel, etc.) to the loading position, the sensor senses the presence of the material at the loading position and controls the extension of the cylinder, thereby causing the mounting plate 3 and the mounting bar 4 to descend, and then the vacuum suction cup 54 is used to absorb the material, thereby achieving automatic absorption of the material.

[0037] In one embodiment, the bottom height of the suction cup 54 is lower than the bottom height of the mounting bar 4. By setting the bottom height of the suction cup 54 to be lower than the height of the mounting bar 4, when the suction cup 54 absorbs the material, the mounting bar 4 will not collide with the material, thereby protecting the material.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
