[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] The present invention provides a packaging box grabbing device, comprising a connecting frame 2 and a limiting plate 3, a transmission device 5 connected between the connecting frame 2 and the limiting plate 3, 24 suction devices 4 connected to the transmission device, the suction devices 4 are used to suck ice cream packaging boxes, and the device can suck 24 ice cream packaging boxes at the same time, thereby improving the packaging efficiency of the ice cream packaging boxes. The suction devices 4 of the device are connected to the limiting plate 3, and the limiting plate 3 can limit the position of the suction devices 4, thereby realizing the grabbing of ice cream packaging boxes at different distances.

[0034] like Figure 1 As shown, the connecting frame 2 is a square frame structure, and a connecting base 1 is connected to the upper side of the connecting frame 2. The connecting base 1 is used to connect to the robot arm, and the robot arm drives the device to move. The left and right sides of the front side of the connecting frame 2 are bolted with connecting plates, and the limit plate 3 is connected to the connecting plate, and the limit plate 3 and the front side of the connecting frame 2 are parallel to each other. A servo motor is fixed to the left side of the connecting frame 2, and a transmission device 5 is connected between the front side of the connecting frame 2 and the limit plate 3. The output end of the servo motor is connected to the transmission device to drive the transmission device 5 to work.

[0035] like Figure 2 and Figure 3 As shown, the limit plate 3 is provided with a slide groove 31 that passes through the limit plate 3. There are six slide grooves 31, and eight blocks 32 are installed in each slide groove 31, and the blocks 32 form a pair. The two blocks 32 are used to limit the position of a suction device 4. Specifically, the suction device 4 can slide between the two blocks 32. When the suction device 4 slides to contact the block 32, the block 32 limits the suction device 4 from continuing to move. When the suction device 4 moves in the opposite direction and moves to the position of another block, the other block 32 limits its position.

[0036] like Figure 6 and Figure 7 As shown, the transmission device 5 includes a driving wheel 51, which is connected to the output shaft of the servo motor, and a driven wheel is rotatably connected to the right end of the vertical plane of the connecting frame 2. A transmission belt 52 is rotatably connected between the driving wheel 51 and the driven wheel. In order to ensure the tensioning effect of the transmission belt 52, the left and right ends of the front side of the connecting frame 2 are connected with a first tensioning wheel 53 and a second tensioning wheel 54 on the same straight line above and below.

[0037] like Figure 4 and Figure 5As shown, the suction device 4 includes a main connecting rod 41 and a suction cup 42 connected to the bottom end of the main connecting rod 41. The main connecting rod 41 descends to drive the suction cup 42 downward, and the suction cup 42 contacts the ice cream box to absorb the ice cream box. The right side of the main connecting rod 41 is connected to a limit rod 411, and the limit rod 411 extends between a pair of stoppers 32. The main connecting rod 41 moves left and right and contacts the stoppers 32, limiting the maximum position of the main connecting rod 41 (such as Figure 3 as shown).

[0038] The left side of the main connecting rod 41 is connected with a moving seat device 43, and the moving seat device 43 includes a sliding seat 431. The sliding seat 431 is provided with two connecting grooves of different heights, namely, a first connecting groove 432 at the top and a second connecting groove 433 at the bottom. The sliding seat 431 is also threadedly connected with a locking rod 434, and the end of the locking rod 434 is connected to the first connecting groove 432, and the end of the locking rod 434 is connected to a friction block. When in use, the upper and lower sides of the transmission belt 52 respectively pass through the first connecting groove 432 and the second connecting groove 433, and the transmission belt 52 contacts the friction block at the end of the locking rod 434. The movement of the transmission belt 52 drives the friction block to move and drives the main connecting rod 41 to move through the sliding seat 431.

[0039] In this embodiment, the rotation of the servo motor drives the transmission belt 52 to rotate, the transmission belt 52 drives the locking rod 434 to move, and drives the main connecting rod 41 to move through the moving seat device 43, thereby controlling the distance between adjacent suction devices 4.

[0040] In order to ensure the stability of the suction device movement, the suction device 4 is also connected to a sliding seat device 44. Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the sliding seat device 44 is connected to the left side of the moving seat device 43, and the sliding seat device 44 includes a connecting seat 441, and the connecting seat 441 is connected to the left side of the sliding seat 431 by bolts. Two pairs of pulleys are provided on the connecting seat 441. Two slide rails 6 are connected to the front side of the connecting frame 2. The two pairs of pulleys are respectively connected to the two slide rails 6 in a rolling manner. Specifically, the connecting seat 441 is connected to a first pulley 442, a second pulley 443, a third pulley 444 and a fourth pulley 445. The first pulley 442 and the second pulley 443 are connected to the upper slide rail 6 in a rolling manner, and the third pulley 444 and the fourth pulley 445 are connected to the lower pulley in a rolling manner. The setting of the slide rail 6 and the pulleys ensures the stability of the left and right movement of the main connecting rod 41.
