[0009] 2. For the automatic feeding device of new energy vehicle workpieces, when the lifting plate moves upward to the top, the two lower adjusting blocks are used to contact the upper adjusting block and continuously extrude, and the two lower adjusting blocks are pushed to move away from each other, thereby driving the two clamping plates away from each other, realizing the function of loosening the clamping of the workpiece. And by contacting the block, it is pushed to disengage from the limit hole. Under the reset action of the second spring, the movable block is pulled to move on the outer wall of the round rod, and the second pushing block below the movable block drives the pushing plate to move, so as to push the workpiece on the lifting plate to achieve the purpose of discharging. At the same time, during the pushing process, the T-shaped slider moves in the radially arranged first movable hole, and then the pushing lengths of the two telescopic pushing plates are expanded, so as to realize more comprehensive pushing of the workpiece.

[0010] 3. The automatic feeding device for new energy vehicle workpieces, when the movable block moves, pushes the second connecting rod to move, and then drives the second push block to move. When the feeding reaches half of the movable rod, the second push block starts to push the movable rod to move on the slide rail, and then moves through the contact plate and the circular upper operating table, so that the moving block moves in the movable hole, thereby pushing the lower rectangular block to move to the left and contact with the guiding block, and the roller on the guiding block contacts the rectangular block, causing the rectangular block to rotate 90 degrees, so that the groove at the bottom of the rectangular block is separated from the extrusion hemisphere, and then rotation is realized, so as to rotate the workpiece on the rotating platform by 90 degrees, which is convenient for subsequent stacking. At the same time, during the movement of the rectangular block, the movable plate is driven to move. By contacting the extrusion rod and realizing extrusion to move upward on the outer wall of the mounting rod, the push rod is further pushed to move upward, realizing the inclination of the hinged rotating platform, so that the workpiece rotated by 90 degrees on the rotating platform slides onto the upper operating table, which further facilitates the workpiece to slide to one place for stacking treatment.

[0015] Working principle: Start the cylinder to work, thereby pushing the lifting block to move, so as to push the lifting plate 3 connected to one side of it to move upward. During the upward movement, the two lower adjusting blocks 16 are separated from the contact with the supporting block 17. At this time, under the extrusion of the first spring 8, the front and back first connecting rods 9 are pushed to move on the fixed rod 7, thereby realizing the mutual approach of the clamping plates 10 to clamp the workpiece placed on the lifting plate 3. At the same time, during the movement, the movable clamping plate 11 slides on the wedge-shaped block 12 through the first push rod connected to the bottom, and the movable clamping plate 11 is pushed to rise by continuously rising, so as to change the clamping height of the workpiece and achieve a better clamping effect. During the upward movement, the steel wire rope on the pulley block 20 will be continuously pulled by the counterweight block, and the length of the steel wire rope is adjusted by the movable pulley. After the two lower adjusting blocks 16 contact the upper adjusting block 18, they move away from each other and push the clamping plates 10 away from each other to achieve the purpose of releasing the clamping.

[0016] When the inclined outer walls of the two lower adjusting blocks 16 come into contact with the clamping block 5012, they will push the clamping block 5012 to move to both sides, causing the clamping block 5012 to disengage from the limiting hole. Under the reset action of the second spring 502, the movable block 503 is pulled to move on the outer wall of the round rod 501, thereby driving the second push rod 504 to drive the material pushing plate 505 to move. During its movement, the two T-shaped sliders 507 move in the first movable hole 508, pushing the two telescopic push plates 506 to move away from each other, thereby increasing the material pushing range. Then, during the process of pushing the material to move, the movable block 503 moves, pulling the steel wire rope to move, and then pulling the movable pulley upward to change the trajectory of the steel wire rope. During the downward movement of the lifting plate 3, since the counterweight block is limited on the support leg 2, the lifting plate 3 pulls the steel wire rope to move downward, and then pulls the movable block 503 connected to the other end to move to the right. After the clamping block 5012 moves to the right and comes into contact with the extrusion block 5013, extrusion occurs, enabling it to enter the limiting hole. Then, under the extrusion of the third spring 5013, the first push block 5010 is pushed to move, thereby clamping the clamping block 5012 in the limiting hole to achieve restoration.

A second return spring is fixedly connected between the connecting block 607 and the inner wall of the horseshoe-shaped block 603.

[0018] Working principle: During the material pushing process, it drives the second connecting rod 509 to move through the leftward movement of the movable block 503, and then drives the second pushing block 615 on one side to move leftward, so that it moves in the chute of the movable rod 613. When it moves to the other side of the chute, during the continuous leftward movement of the movable block 503, it pushes the movable rod 613 to move, and then drives the contact plate to move leftward, so that it contacts the rotating platform 602, thereby pushing the rotating platform 602 to move to the left. During the movement, through the movement of its moving block in the groove, the rectangular block 605 moves to the left and contacts the roller on the left guide block 604, and squeezes the rectangular block 605 to rotate, thereby driving the overall rotating shaft 606 and the rotating platform 602 to rotate. After the rotation ends, its hinge just rotates, so that its hinge is aligned with the second movable hole for rotation, and during the movement of the connecting block 607, by contacting the extrusion rod 611, an upward extrusion is generated, and then the extrusion rod 611 is pushed upward, thereby pushing the feeding rod 612 connected thereto to move upward, and pushing one side of the rotating platform 602 to rotate around the hinge point, thereby generating an inclination, facilitating the workpiece rotated by 90 degrees to slide onto the upper operation table 601 to achieve rapid stacking. Then, when the movable rod 613 does not apply force to the rotating platform 602, under the pulling of the second return spring, the connecting block 607 is pulled to move rightward. When the rectangular block 605 does not contact the guide block 604, its bottom contacts the edge of the groove through the extrusion hemisphere 609, and under the action of the first return spring, the extrusion hemisphere 609 is pushed upward to move into the groove, so that its driving rectangular block 605 generates a deflection angle, so that during the reset process, the rectangular block 605 is pulled to continue rotating with the rectangular block 605 on the right side, and when the rectangular block 605 continues to move leftward and breaks away from the contact with the rectangular block 605 on the right side, a deflection angle is continuously generated through the extrusion hemisphere 609, facilitating the next flip, and at the same time, the rotating platform 602 at its top rotates 180 degrees to achieve cyclic stacking.
