[0027] like Figures 1 to 5 As shown, the present application provides a multifunctional clamp for a palletizing robot, including a connecting seat 1, the connecting seat 1 is used to connect with the palletizing robot, a clamping assembly 3 for clamping goods is provided below the connecting seat 1, and a first driving assembly 2 for driving the clamping assembly 3 to work is also provided below the connecting seat 1;

[0028] The clamping assembly 3 includes two groups of fixed blocks 31 symmetrically arranged, two groups of movable blocks 32 are arranged in parallel on one side of the fixed block 31, and a second driving assembly 33 for driving the two groups of movable blocks 32 to move toward each other is arranged inside the fixed block 31;

[0029] The fixing block 31 has an inner cavity 311 formed therein, and a slide groove 312 is formed on one side of the fixing block 31 , and the slide groove 312 has two groups;

[0030] The second driving assembly 33 includes a second motor 331 installed on the outside of the fixed block 31, the output shaft of the second motor 331 is rotatably connected to the inside of the inner cavity 311 and is sleeved with a gear 332, the outer side of the gear 332 is meshed with a rack 333, and there are two groups of racks 333, the two groups of racks 333 are respectively located at the top and bottom of the gear 332, the two groups of racks 333 are respectively slidably connected to the inside of the inner cavity 311, one side of the two groups of racks 333 is provided with a sliding rod 334 slidably connected to the sliding groove 312, and the two groups of sliding rods 334 are respectively connected to the two groups of movable blocks 32.

[0031] In this embodiment, if Figure 2 As shown, in the initial state, the ends of the two groups of movable blocks 32 on one side of the fixed block 31 are in contact, and the stacking robot moves the clamping assembly 3 to the position where the box goods need to be grabbed, and the two groups of fixed blocks 31 are moved toward each other by the first driving assembly 2, so that the distance between the two groups of fixed blocks 31 is shortened, so that the movable block 32 on one side of the fixed block 31 is in contact with the outer side of the box goods, thereby completing the clamping of the box goods, and then after the clamping assembly 3 is moved to a suitable position by the robot, the first driving assembly 2 drives the two groups of fixed blocks 31 to release the box goods, thereby completing the stacking of the box goods, when it is necessary to grab box goods of different sizes, the second motor 331 is controlled to be turned on, and the second motor 331 drives the gear 332 to rotate, and the gear When the gear 332 is meshed with the two sets of racks 333, the gear 332 drives the two sets of racks 333 to move toward each other inside the inner cavity 311, and the two sets of racks 333 drive the sliding rod 334 to slide along the two sets of sliding grooves 312, and the two sets of movable blocks 32 are driven to move toward each other through the two sets of sliding rods 334, so that the two ends of the two sets of movable blocks 32 can extend to the outside of the end of the fixed block 31, and then under the operation of the first drive assembly 2, the two sets of fixed blocks 31 drive the movable blocks 32 to clamp the box cargo, and the two sets of movable blocks 32 extend to the outside of the fixed block 31 to expand the clamping range. For a longer box, the extension of the four sets of movable blocks 32 makes it more stable when grabbing the box cargo, which is more convenient than replacing splints of different sizes and can effectively improve work efficiency.

[0032] like Figures 4 to 5 As shown, the first driving component 2 includes a guide rail 23 arranged at the lower end of the connecting seat 1, and a slider 24 is slidably connected to the lower end of the guide rail 23. A fixed plate 25 is provided at the lower end of the slider 24. A guide rod 251 movably penetrates the fixed plate 25. The bottom of the guide rod 251 is connected to the fixed block 31. The guide rod 251 is used to provide support for the fixed block 31. A first motor 21 is installed on one side of the guide rail 23, and a bidirectional screw rod 22 is connected to the output shaft end of the first motor 21. The outer side of the bidirectional screw rod 22 is threadedly connected to two groups of connecting blocks 221, and the connecting block 221 is connected to the fixed plate 25.

[0033] In this embodiment, the bidirectional screw rod 22 is driven to rotate by the first motor 21, and under the connection between the guide rail 23 and the slider 24, the two groups of connecting blocks 221 drive the fixed plate 25 to move toward each other, and the guide rod 251 on the fixed plate 25 drives the fixed block 31 to move, thereby achieving a shortening of the distance between the two groups of fixed blocks 31. Conversely, the bidirectional screw rod 22 is driven to rotate in the opposite direction by the first motor 21, so that the two groups of fixed plates 25 rotate in the opposite direction, thereby increasing the distance between the two groups of fixed blocks 31, thereby achieving the clamping and release of the box cargo.

[0034] like Figure 5 As shown, a cylinder 252 is installed on the top of the fixed plate 25, and the telescopic end of the cylinder 252 movably passes through the fixed plate 25 and is connected to the fixed block 31.

[0035] In this embodiment, the cylinder 252 drives the fixed block 31 to move downward, so that the distance between the fixed block 31 and the fixed plate 25 is increased, so that when grabbing box goods, higher box goods can be grabbed at the lower end, further increasing its stability when grabbing goods.

[0036] In summary: the multifunctional palletizing robot clamp provided in the present application demonstrates its various practical functions. First, through the operation of the second drive assembly 33, the two groups of movable blocks 32 located on one side of the fixed block 31 can move toward each other and extend to the outside of the end of the fixed block 31, so as to expand the clamping range, so that it can be more stable when grabbing longer box goods. This function makes the clamp suitable for goods of different sizes, reflecting its versatility and flexibility. Secondly, the fixed block 31 is pushed down by the cylinder 252 to control the distance between the fixed block 31 and the fixed plate 25, so that the fixed block 31 can be at the lower end of the box when clamping higher box goods, further increasing its stability when grabbing goods. This function enables the clamp to maintain stability when handling goods of different heights.
