The axis of the electromagnetic disk 203 coincides with the axis of the moving seat 1. When the telescopic cylinder 201 is started, the electromagnetic disk 203 at the output end is driven to move downward, and the electromagnetic disk 203 adsorbs and fixes the workpiece for lifting.

[0027] In order to achieve simultaneous transportation during lifting, a storage table 301 is provided in the transportation component 3, the bottom of the storage table 301 is fixedly connected to the moving seat 1, an installation chamber 302 is provided inside the storage table 301, two moving plates 303 are built in the installation chamber 302, the moving plates 303 are slidably connected to the inner wall of the installation chamber 302, a plurality of fixing grooves 304 are provided on the end faces of the two moving plates 303 close to each other, the plurality of fixing grooves 304 are evenly distributed along the length direction of the moving plates 303, a return spring 305 is built in the fixing groove 304, both ends of the return spring 305 are in contact with the two moving plates 303, the ends of the two moving plates 303 away from each other are fixedly connected with a connecting plate 307, sliding windows 306 are provided on both sides of the storage table 301, and the connection One end of the plate 307 away from the moving plate 303 extends to the outside through the sliding window 306, and the connecting plate 307 is fixedly connected to a connecting seat 308 at one end outside the storage table 301. A clamping plate 309 is fixedly connected to the top of the connecting seat 308. The clamping plate 309 is placed on the top of the storage table 301. The end surfaces of the two clamping plates 309 close to each other are fixedly connected with a buffer strip 310. A tilting window 311 that runs through the connecting seat 308 is opened on the surface of the connecting seat 308. The tilting window 311 is built with a trigger rod 312. The trigger rod 312 is slidably connected to the inner wall of the tilting window 311. The bottom of the trigger rod 312 is fixedly connected to a connecting rod 313. A fixed cylinder 314 is sleeved on the bottom surface of the connecting rod 313. The connecting rod 313 is slidably connected to the inner wall of the fixed cylinder 314 The bottom of the inner cavity of the fixed cylinder 314 is fixedly connected with a connecting cylinder 315, and the connecting cylinder 315 has a built-in telescopic spring 316. One end of the telescopic spring 316 is fixedly connected to the bottom of the inner cavity of the connecting cylinder 315, and the other end of the telescopic spring 316 is fixedly connected to the connecting rod 313. A connecting frame 317 is sleeved on the bottom of the fixed cylinder 314, and one end of the connecting frame 317 is fixedly connected to the fixed cylinder 314. The end of the connecting frame 317 away from the fixed cylinder 314 is sleeved on the surface of the output end of the telescopic cylinder 201, and the connecting frame 317 is fixedly connected to the output end of the telescopic cylinder 201. The storage platform 301 can be moved up, down, left, and right with the scissor-type lifts at both ends of the driving rod 102. The workpiece is placed on the storage platform 301. During the downward movement of the telescopic cylinder 201, the telescopic spring 316 is fixedly connected to the connecting rod 313. The connecting frame 317 at the output end of the retracting cylinder 201 will also move downward, and the connecting frame 317 drives the fixed cylinder 314 and the connecting rod 313 at both ends to move downward. The downward movement of the connecting rod 313 drives the trigger rod 312 at the top to move downward. As the trigger rod 312 moves downward, the distance between the contact points of the two trigger rods 312 and the connecting seat 308 will become closer and closer, so that the connecting seat 308 squeezes the moving plate 303 and the return spring 305, and finally makes the clamping plate 309 on the top of the connecting seat 308 close to the workpiece, and fixes the workpiece on the storage table 301. Through the design of the device, the electromagnetic disk 203 at the bottom of the telescopic cylinder 201 can move downward to adsorb other workpieces while fixing the workpiece on the storage table 301, and multiple and various workpieces can be transported at the same time.

[0028] Working principle: The moving seat 1 can drive itself to move horizontally through the driving rod 102, and the two ends of the driving rod 102 are respectively fixed on the corresponding scissor lift, so that the moving seat 1 can also move in the vertical direction to realize the transportation of materials;

[0029] When hoisting the workpiece, the telescopic cylinder 201 can be started to drive the electromagnetic disk 203 at the output end to move downward, and the electromagnetic disk 203 adsorbs and fixes the workpiece for hoisting;

[0030] When carrying a workpiece, the storage table 301 can be moved up, down, left, and right along with the scissor-type lifts at both ends of the driving rod 102. The workpiece is placed on the storage table 301. When the telescopic cylinder 201 moves downward, the connecting frame 317 at the output end of the telescopic cylinder 201 also moves downward. The connecting frame 317 drives the fixed cylinder 314 and the connecting rod 313 at both ends to move downward. The downward movement of the connecting rod 313 drives the trigger rod 312 at the top to move downward. As the trigger rod 312 moves downward, the distance between the contact points of the two trigger rods 312 and the connecting seat 308 will increase. The connecting seat 308 squeezes the moving plate 303 and the return spring 305, and finally the clamping plate 309 on the top of the connecting seat 308 is close to the workpiece, and the workpiece is fixed on the storage table 301. Through the design of the device, the electromagnetic disk 203 at the bottom of the telescopic cylinder 201 can move down to absorb other workpieces while the workpiece is fixed on the storage table 301, and multiple and various workpieces can be transported at the same time. Compared with the comparative device, only one telescopic cylinder 201 is used, and the production cost and use cost of the overall device are reduced;

[0031] When the telescopic cylinder 201 drives the fixed frame 202 to move downward, the trigger rod 312 drives the clamping plate 309 to fix the workpiece. If the electromagnetic disk 203 does not move downward enough, the output end of the telescopic cylinder 201 will continue to move downward. At this time, the clamping plate 309 has fixed the workpiece, and the connecting rod 313 cannot move downward, but the fixed cylinder 314 will continue to move downward, stretching the telescopic spring 316. Later, when the output end of the telescopic cylinder 201 moves upward, the fixed cylinder 314 moves upward and its telescopic spring 316 will shrink. The top connecting rod 313, trigger rod 312 and clamping plate 309 are not affected by it, and will not affect the fixation of the material on the top of the storage table 301.
