[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figure 1 shown, the suction cup adjustment device includes a frame 100, a first arm body 200 rotatably arranged on the frame 100, a second arm body 300, and a suction cup assembly 600 movably arranged at both bottom ends of the first arm body 200 and the second arm body 300. After adjusting the position of the suction cup assembly 600, materials of different specifications and sizes can be sucked.

[0035] As Figure 1 shown, the suction cup adjustment device of this embodiment mainly includes: a frame 100, a first arm body 200, a second arm body 300, and a suction cup assembly 600.

[0036] More specifically, in this embodiment, an internal gear ring 110 is fixedly installed at the bottom end of the frame 100. At the same time, referring to Figure 3 shown, a connecting plate 120 is fixedly installed in the middle of the frame 100. Connecting frames 121 fixedly connected to the connecting plate 120 are arranged at intervals on the lower end face facing the connecting plate 120. And referring to Figure 4As shown, in this embodiment, the connecting frame 121 has a cross-shaped structure. Four mounting grooves 1211 are arranged around the connecting frame 121 along its contour for fixing to the connecting plate 120 by bolts. A core shaft 122 is fixedly arranged at the middle position between the connecting plate 120 and the connecting frame 121. A first motor 130 is installed at a position on the frame 100 coaxial with the core shaft 122. A first driving wheel 131 is fixedly installed on the output end of the first motor 130, and a first transmission belt 132 and a second transmission belt 133 are also sleeved on the first driving wheel 131 at intervals. A second motor 140 is installed at the edge position of the frame 100, and a second driving wheel 141 is fixedly installed on the output end of the second motor 140.

[0037] As Figure 3 shown, the first arm body 200 and the second arm body 300 are cross-distributed at the interval between the connecting plate 120 and the connecting frame 121. Referring to Figure 6 and 7 shown, in this embodiment, shaft holes are respectively formed at the middle positions of the first arm body 200 and the second arm body 300 corresponding to the core shaft 122 and are rotatably sleeved on the core shaft 122.

[0038] To enable the first arm body 200 to adjust its angle, two symmetrically arranged first driven wheels 220 are rotatably arranged on the upper end surface of the first arm body 200. In order to transmit the torque of the first motor 130 to the first driven wheels 220, the second transmission belt 133 is also sleeved on the two first driven wheels 220. A first gear 221 fixedly connected to the first driven wheel 220 is arranged at the top of each first driven wheel 220, and each first gear 221 is in contact engagement with the internal gear ring 110.

[0039] To enable the second arm body 200 to rotate around the core shaft 122 and rotate in the opposite direction relative to the first arm body 200, referring to Figure 1As shown, two symmetrically arranged second gears 320 and two third gears 330 respectively meshing with the second gears 320 are rotatably provided on the upper end surface of the second arm body 200. A second driven wheel 321 fixedly connected to the second gear 320 is provided at the top of each second gear 320. To achieve torque transmission, the first transmission belt 132 is also sleeved on the two second driven wheels 321. A fourth gear 331 fixedly connected to the third gear 330 is provided at the top of each third gear 330, and each fourth gear 331 is in contact and meshes with the internal gear ring 110. After the first motor 130 transmits the torque to the second driven wheel 321, the meshing second gear 321 and third gear 330 reverse-transmit the torque to the fourth gear 331, so that the rotation directions of the fourth gear 331 and the first gear 221 on the first arm body 200 are opposite, causing the first motor 130 to drive the second arm body 300 and the first arm body 200 to rotate in opposite directions around the core shaft 122, thereby flexibly adjusting the coverage areas of the first arm body 200 and the second arm body 300.

[0040] Reference Figure 5 As shown, in this embodiment, the suction cup assembly 600 includes a slider 610 and a suction cup 620 fixedly installed on the slider 610. In this embodiment, four suction cup assemblies 600 are provided, and the suction cup assemblies 600 are distributed on the lower end surfaces of the first arm body 200 and the second arm body 300. To be able to adjust the distance between the suction cup assemblies 600, reference Figure 4 As shown, two first sliding grooves 210 and two second sliding grooves 310 are symmetrically provided on the lower end surfaces of the first arm body 200 and the second arm body 300 along their respective length directions. The suction cup assemblies 600 are respectively slidably arranged in each first sliding groove 210 and second sliding groove 310 through the sliders 610. At the same time, reference Figure 6 As shown, two pairs of rotatably arranged sprockets 400 are symmetrically provided at the bottoms of the first arm body 200 and the second arm body 300. A transmission chain 420 is sleeved between each pair of sprockets 400. A clamping block 421 is fixedly provided on the inner side of each transmission chain 420 corresponding to the slider 610 on the suction cup assembly 600. Reference Figure 5As shown, in this embodiment, the clamping block 421 is in a U-shaped structure and sleeved on both sides of the corresponding slider 610. In this way, the rotation of the transmission chain 420 can drive the movement of the clamping block 421, thereby driving the suction cup assembly 600 to slide along the chute. At the bottom end of each sprocket 400 near the mandrel 122, a planetary gear 410 is fixedly arranged. To enable the four planetary gears 410 to rotate simultaneously, a sun gear 500 is rotatably arranged at the end of the mandrel 122 corresponding to the planetary gears 410. The sun gear 500 is in contact and meshed with the four planetary gears 410. A third driven wheel 510 is fixedly arranged on the end face of the sun gear 500. To achieve torque transmission, a third transmission belt 142 is sleeved between the third driven wheel 510 and the second driving wheel 141. In other embodiments not given, the four suction cup assemblies 600 can also be independently and slidably arranged in the corresponding chutes, and can be adjusted manually and temporarily fixed by pins for the suction cup assemblies 600.

[0041] To ensure the operation accuracy of the device in this embodiment, the first driving wheel 131, the second driving wheel 141, the first driven wheel 220, the second driven wheel 321, and the third driven wheel 510 in the embodiment are all synchronous belt wheels, and the corresponding first transmission belt 132, the second transmission belt 133, and the third transmission belt 142 are all synchronous belts.

[0042] In other embodiments not given, the suction cup assemblies 600 can also be correspondingly installed on the connecting frame 121 through the mounting grooves 1211 for adsorbing and fixing the middle position of the material to ensure more reliable adsorption.

[0043] The working process of the suction cup adjustment device of the present invention will be described below with reference to the drawings:

[0044] First, adjust the angle between the first arm 200 and the second arm 300 for different-sized materials to make the arm coincide with the diagonal of the material. Specifically, start the first motor 130, and drive the two first gears 221 to rotate together through the first driving wheel 131. Refer to Figure 8 As shown, assuming that the first motor 130 drives the first driving wheel 131 to rotate counterclockwise, the first arm 200 is driven to rotate clockwise through the meshing of the first gear 221 and the internal gear ring 110, and at the same time, the second arm 300 is driven to rotate in the opposite direction relative to the first arm 200 to Figure 8 the position shown. Assuming that at this time, the first arm 200 and the second arm 300 rotate to the position where they coincide with the diagonal of the material, then the second motor 140 is started, and the torque is transmitted through the second driving wheel 141 to drive the sun gear 500 on the third driven wheel 510 to rotate. The rotation of the sun gear 500 further drives the four meshing planetary gears 410 to rotate in the same direction. Refer to Figure 9It is assumed that the sun gear 500 shown rotates clockwise, which drives the four planet gears 410 to rotate counterclockwise, and then drives the four transmission chains 420 to rotate synchronously counterclockwise. The four suction cup assemblies 600 are pushed by the clamping blocks 421 to move simultaneously towards the center of the device along their respective chutes until the suction cup assemblies 600 move to the four corner positions of the material, completing the position adjustment of the suction cup assemblies 600, so as to adapt to materials of different sizes and proportions.

[0045] In the suction cup adjustment device of the present invention, the rotation of the first arm body 200 and the second arm body 300 can make the coverage area of the arm body wider, so that the suction cup assemblies 600 on the arm body can no longer only move along a fixed inclination angle, and the adjustment range is wider, thus it can be applied to materials of different shape proportions. Then, through the meshing of the sun gear 500 and the planet gears 410, the transmission chains 420 can be driven to rotate synchronously. The transmission chains 420 can push the suction cup assemblies 600 to slide back and forth along the chutes through the corresponding clamping blocks 421 thereon, adjusting the distance between the suction cup assemblies 600, so as to adapt to materials of different sizes. The moving direction of the clamping blocks 421 is always the same as the moving direction of the suction cup assemblies 600, enabling the suction cup assemblies 600 to move smoothly and improving the operation reliability of the device.

[0046] Inspired by the above ideal embodiments according to the present invention, through the above description, relevant staff can make various changes and modifications completely within the scope not deviating from the present invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
