[0021] Reference Figure 2 The outer surface of each L-shaped connecting rod 3 is fixed with a fixing ring 44 by bolts for installing the L-shaped lifting rod 41. A sliding rod 45 and a first bidirectional screw 414 for rotation are integrally arranged between the two fixing rings 44. One end of the sliding rod 45 passes through the inner ring of the bearing 42. The inner ring of the bearing 42 is threadedly connected with the first bidirectional screw 414 to drive the bearing 42 to move forward and backward. A limiting block 43 is integrally arranged on the front side of the outer ring of each bearing 42. The upper surface of the limiting block 43 is pressed against the outer surface of the sliding rod 45 to limit the rotation position of the L-shaped connecting rod 3. When the L-shaped lifting rod 41 rotates outward, the limit block 43 is separated from the outer surface of the sliding rod 45. When the L-shaped lifting rod 41 moves up and rotates inward, the limit block 43 is pressed against the outer surface of the sliding rod 45 to limit the L-shaped lifting rod 41 so that the inner end of the L-shaped lifting rod 41 is located in the stacking hole of the module 13, so that the module 13 can be lifted when the L-shaped lifting rod 41 moves up; the protruding block 46 is triangular or rectangular, and the lower surface of the protruding block 46 is welded to the upper surface of the L-shaped lifting rod 41.

During this process, the ball 47 at the inner end of the L-shaped lifting rod 41 will come into close contact with the top wall of the stacking hole of the module 13 or the outer side of the module 13. The ball 47 is subjected to pressure, which will cause the connecting rod 48 to compress the spring 49 and shrink into the circular groove 410, thereby reducing the length of the inner end of the L-shaped lifting rod 41, so that the L-shaped lifting rod 41 can be quickly and smoothly separated from the stacking hole of the module 13 or enter the stacking hole; after the L-shaped lifting rod 41 is separated from the stacking hole of the module 13 or the outer side of the module 13, the spring 49 will push the connecting rod 48 to extend outward to move the ball 47 outward, thereby increasing the length of the L-shaped lifting rod 41 and providing a suitable supporting force for the L-shaped lifting rod 41; refer to Figure 6 A lifting mechanism 9 is provided in the support frame 2, and the lifting mechanism 9 includes a servo motor 91 and a U-shaped block 92. The servo motor 91 is fixed to the upper surface of the support frame 2, and the U-shaped block 92 is slidably installed on the periphery of the support frame 2. A No. 2 slide groove 11 is provided on the inner wall of the support frame 2, and a counterweight block 95 is slidably provided between the two No. 2 slide grooves 11; a toothed disc 93 is fixed to the output end of the servo motor 91, a connecting shaft 12 is fixed to one side of the toothed disc 93, and one end of the connecting shaft 12 is rotatably connected to the inner wall of the support frame 2, and a chain 94 is meshed on the periphery of the toothed disc 93, and the two ends of the chain 94 are respectively rotatably arranged with the counterweight block 95 and the upper surface of the U-shaped block 92 through connecting pins to drive the U-shaped block 92 to rise and fall.

[0023] refer to Fig.10An adjusting member 10 is provided on the front side of the U-shaped block 92, and the adjusting member 10 includes a No. 2 bidirectional screw rod 1001 and a slider 1003; the No. 2 bidirectional screw rod 1001 is rotatably installed on the front side of the U-shaped block 92, and a No. 3 slide groove 1002 is opened, and the slider 1003 is slidably installed in the No. 3 slide groove 1002, the No. 2 bidirectional screw rod 1001 and the slider 1003 are threadedly arranged, and the lower surfaces of the two sliders 1003 are respectively fixed to the upper end of the L-shaped connecting rod 3 by bolts, and when the slider 1003 moves, the two L-shaped connecting rods 3 are driven to drive the left and right opposing L-shaped lifting rods 41 to move relative to or toward each other, so as to flexibly control the distance between the left and right opposing L-shaped lifting rods 41, and can adapt to modules 13 of different widths.

[0024] Working principle: The factory transports the modules 13 to be stacked to the designated location, and then the device moves to the vicinity of the modules 13; when the first module 13 is transferred, the servo motor 91 in the lifting mechanism 9 is first started to drive the toothed disc 93 to rotate and the chain 94 moves downward, and the chain 94 The downward movement will cause the U-shaped block 92 to move downward accordingly. In the process of the U-shaped block 92 moving downward accordingly, the L-shaped connecting rod 3 will move downward accordingly. The downward movement of the L-shaped connecting rod 3 drives the L-shaped lifting rod 41 to move downward to the position above the stacking hole of the module 13; then the L-shaped lifting rod 41 is controlled to move downward. When the L-shaped lifting rod 41 first contacts the upper end of the module 13 during the downward movement, it will be blocked by the upper edge of the module 13, causing multiple L-shaped lifting rods 41 to rotate outward to form an inclined downward state. When the L-shaped lifting rod 41 in the inclined state continues to move downward to form an inner end of the L-shaped lifting rod 41 opposite to the stacking hole, the L-shaped lifting rod 41 is no longer subject to the resistance of the module 13. At this time, the inner end of the L-shaped lifting rod 41 will be in the stacking hole, and the stacking hole of the module 13 can be quickly positioned and locked into place; Then, the lifting mechanism 9 is started again. When the servo motor 91 rotates, the chain 94 moves up, driving the U-shaped block 92 to move up accordingly, and each L-shaped lifting rod 41 moves up, driving the module 13 to move up accordingly. Then, the electric telescopic rod 7 can be started to push the support frame 2 to move the module 13 horizontally, and then the device is moved. After determining the position of the first module 13 to be transferred, the lifting mechanism 9 is operated to move the first module 13 downward and place it on the ground. After the first module 13 is placed on the ground, as the lifting mechanism 9 continues to move the L-shaped lifting rod 41 downward, the L-shaped lifting rod 41 will be blocked by the lower edge of the stacking hole, causing the L-shaped lifting rod 41 to rotate outward again. Then, as the L-shaped lifting rod 41 continues to move downward, the L-shaped lifting rod 41 will slide out of the stacking hole and separate from the module 13. The whole process can automatically position and clamp the module 13, and automatically release the module 13 at the same time, so as to realize automatic clamping and stacking of the module 13. The cyclic operation in sequence can perform multi-layer stacking of multiple modules 13, thereby improving the stacking efficiency of the module 13. After the modules 13 are stacked, when the electric telescopic rod 7 drives the L-shaped lifting rod 41 to move backward, the ball 47 will roll on the side of the module 13, thereby preventing the device from scratching the module 13; When the inner end of the L-shaped lifting rod 41 is in the stacking hole of the module 13, the protruding block 46 will be in close contact with the top wall of the stacking hole, thereby increasing the friction with the module 13. During the rotation of the module 13, the module 13 can be prevented from sliding off the L-shaped lifting rod 41 and being damaged, thereby increasing the stability and safety of the transfer of the module 13. In addition, before use, the two sliders 1003 can drive the two L-shaped connecting rods 3 to drive the left and right opposing L-shaped lifting rods 41 to move relative to or toward each other by twisting the No. 2 bidirectional screw 1001 in the adjusting member 10, and flexibly control the distance between the left and right opposing L-shaped lifting rods 41 to adapt to modules 13 of different widths; at the same time, the front and rear opposing bearings 42 on each L-shaped connecting rod 3 can also move relative to or toward each other by twisting the No. 1 bidirectional screw 414, and the distance between the front and rear opposing bearings 42 can be flexibly changed, which can flexibly change the distance between the front and rear opposing L-shaped lifting rods 41 under each L-shaped connecting rod 3, adapting to the two stacking holes with different spacings between the front and rear, thereby increasing the adaptation effect of the device to the module 13.
