The telescopic arm 403 is extended or retracted by a driving component, and a grabbing component is arranged on the second telescopic arm 403. Specifically, during stacking, the assembly line 6 conveys the turnover box to the lifting and conveying platform 2, and then the second lifting component 5 drives the mounting frame 401 to move downward, and then the grabbing component clamps the upper edge of the turnover box and lifts it to a certain distance, so that the grabbed turnover box does not hinder the next turnover box from entering the lifting and conveying platform 2. When the next turnover box is conveyed to the lifting and conveying platform 2, the second lifting component 5 drives the mounting frame 401 to move downward and stacks it up and down together, and then the grabbing component grabs the upper edge of the turnover box on the lower layer and lifts it to a certain distance, and so on and so forth until the turnover box is stacked to the indicated position. After a certain number of stacks are stacked, the first lifting component 3 drives the lifting and conveying platform 2 to move down to leave space for the mounting frame 401 to descend. The mounting frame 401 descends to the bottom along the frame 1, and then the driving component drives the first telescopic arm 402 and the second telescopic arm 403 to extend, and the stacked turnover boxes are placed on the AGV trolley 7. The AGV trolley 7 can transport the turnover boxes along the specified path; when destacking, the lifting and conveying platform 2 and the mounting frame 401 are both lowered to the bottom of the frame 1, and then the AGV trolley 7 transports the entire stack of turnover boxes to the grabbing position of the grabbing component, and then the grabbing component clamps the turnover boxes on the bottom layer, and then lifts the entire stack of turnover boxes, and then the lifting and conveying platform 2 moves along the frame 1 It rises to a height flush with the assembly line 6, then the mounting frame 401 descends, and the whole stack of turnover boxes is placed on the lifting and conveying platform 2. Then the mounting frame 401 rises to the height of one turnover box, grabs the whole stack of turnover boxes on the upper layer and lifts them a certain distance, and the turnover boxes remaining on the lifting and conveying platform 2 are sent to the designated position via the assembly line 6. By integrating the grabbing robot arm 4 with the lifting and conveying platform 2 to match the height of the conventional assembly line 6, there is no need to add an additional turnover box elevator, and no additional factory space is required, which effectively reduces the cost to realize the stacking and destacking functions, and the lifting and conveying platform 2 can be lifted up and down, and can match assembly lines 6 of different heights, and has strong adaptability.

[0028] like Figure 2As shown, the lifting and conveying platform 2 includes a support frame 201, which is slidably matched with a guide shaft 202 vertically arranged on the frame 1.

The electric roller has a built-in motor inside, which can convey the turnover box to the assembly line 6, or convey the turnover box on the assembly line 6 to the grabbing position of the grabbing robot arm 4.

[0029] like Figure 2 As shown, a first baffle 204 is provided on both sides of the support frame 201, and a second baffle 205 is provided at one end of the support frame 201.

[0030] like Figure 2 As shown, a first sensor 206 is installed on the support frame 201 in front of the second baffle 205. Specifically, the first sensor 206 is used to detect the turnover box on the roller 203. When the assembly line 6 transports the turnover box to the support frame 201, the first sensor 206 detects the turnover box and the roller 203 stops rotating.

[0031] like Figure 3 As shown, the first lifting assembly 3 includes a first motor 301 and a rack 302 vertically arranged on the frame 1. A transmission shaft 303 is rotatably provided at the bottom of the support frame 201. Gears 304 meshing with the rack 302 are provided at both ends of the transmission shaft 303. The first motor 301 is used to drive the transmission shaft 303 to rotate. Specifically, the first motor 301 drives the gear 304 to rotate through the transmission shaft 303.

Specifically, the second motor 404 drives the first synchronous belt 405 to rotate, driving the first telescopic arm 402 to move forward along the mounting frame 401, while driving the second telescopic arm 403 to extend along the first telescopic arm 402 through the first synchronous wheel 409 and the second synchronous belt 410. The second motor 404 drives the first telescopic arm 402 to retract along the mounting frame 401, while driving the second telescopic arm 403 to retract along the first telescopic arm 402 through the second synchronous wheel 412 and the third synchronous belt 413.

[0033] like Figure 4 , Figure 5 As shown, the grabbing assembly includes a cylinder 406 installed on the second telescopic arm 403, and a clamping block 408 is installed at the output end of the cylinder 406. The clamping block 408 is provided with a guide rod 407 that slides with the second telescopic arm 403. Specifically, the cylinder 406 drives the clamping block 408 to extend, and the clamping block 408 clamps the upper edge of the turnover box, thereby improving the stability during grabbing through the guide rod 407.

[0034] like Figure 5 As shown, a second sensor 411 is provided at the end of the second telescopic arm 403. Specifically, when the first telescopic arm 402 and the second telescopic arm 403 drive the grabbing assembly to extend to clamp the turnover box, the second sensor 411 detects the position of the turnover box to avoid a collision when the first telescopic arm 402 and the second telescopic arm 403 are extended due to the displacement of the turnover box.

[0035] like Figure 7 As shown, the second lifting assembly 5 includes a third motor 501 and a chain 502. The mounting frame 401 is fixedly connected to the chain 502. The third motor 501 drives the mounting frame 401 to move up and down along the frame 1 through the chain 502. Specifically, the third motor 501 drives the chain 502 to rotate, driving the mounting frame 401 to rise or fall along the frame 1.

[0036] When used specifically, Figure 8As shown, during palletizing, the assembly line 6 conveys the turnover box to the lifting and conveying platform 2, and then the second lifting component 5 drives the grabbing robot arm 4 to move down, grab the upper edge of the turnover box and lift it to a certain distance, so that the grabbed turnover box does not hinder the next turnover box from entering the lifting and conveying platform 2. When the next turnover box is conveyed to the lifting and conveying platform 2, the second lifting component 5 drives the grabbing robot arm 4 to move down and stack it up and down together, and then the grabbing robot arm 4 grabs the upper edge of the turnover box on the lower layer and lifts it to a certain distance, and so on and so forth. After the turnover boxes are stacked to a specified number, the first lifting component 3 drives the lifting and conveying platform 2 to move down to leave space for the grabbing robot arm 4 to descend, and the grabbing robot arm 4 descends to the bottom along the frame 1, and then the stacked The turnover boxes are placed on the AGV trolley 7, and the turnover boxes are transported along the specified path by the AGV trolley 7; when destacking, the lifting and conveying platform 2 and the grabbing robot arm 4 are both lowered to the bottom of the frame 1, and then the AGV trolley 7 transports the whole stack of turnover boxes to the grabbing position of the grabbing robot arm 4, and then the grabbing robot arm 4 grabs the turnover boxes on the bottom layer, and then lifts the whole stack of turnover boxes, and then the lifting and conveying platform 2 rises along the frame 1 to the same height as the assembly line 6, and then the grabbing robot arm 4 descends, and places the whole stack of turnover boxes on the lifting and conveying platform 2, and then the grabbing robot arm 4 rises to the height of one turnover box, grabs the whole stack of turnover boxes on the upper layer and lifts it a certain distance, and the turnover boxes left on the lifting and conveying platform 2 are sent to the designated position through the assembly line 6.
