A screw machine 45 is arranged inside the assembly platform 44. A fixing head 42 is arranged above the third cylinder 40. The worker needs to place the end cap on the conveyor belt 2, and then start the conveyor belt 2. The conveyor belt 2 transports the end cap to the designated area. At this time, the detection plate 54 at the bottom of the end cap will detect the end cap to determine whether it is in the correct position and whether the angle needs to be adjusted. Then the first cylinder 3 starts to control the correction ring 4 to fix and correct it. Then the second cylinder 10 retracts to drive the conveyor cylinder 12 to descend, and then the end cap will be conveyed by the conveyor cylinder. 12 grabs and transports upward, then the second cylinder 10 rebounds and sends the end cap to the next area, the grabbing cylinder 20 grabs the transported end cap and then transfers it to the installation area through the slider 14, after arriving at the designated area, the grabbing cylinder 20 descends, and the end cap contacts the motor core 33 on the feeding platform 31, and then they will be attracted to each other through the magnetic attraction of the grabbing cylinder 20, then the assembly platform 44 rises and rotates, and the screw machine 45 is used to drive the screws into it, then the finished product platform 30 rotates and catches the finished product and transports it to the back side.

After the end cover is conveyed to the designated area on the conveyor belt 2 and inspected, the first cylinder 3 is started to control the deflection correction ring 4 to slide inward by extending the gas rod, and then the rotating ring 5 in the deflection correction ring 4 will fit the end cover, thereby ensuring that the end cover is located in the center position on the conveyor belt 2. At this time, the detection The sheet 7 will fit with the arc-shaped bracket 9 of the rotating circle 5 on the other side, and the clamping force will be judged by the contact pressure to prevent the end cover from being damaged due to being too loose and unable to be in the center position or being too tight and causing the end cover to be clamped and damaged. Then the rotating circle 5 will rotate in the correction circle 4, so as to adjust the angle of the end cover so that it can be in the corresponding screw hole position in the subsequent installation process. Then the conveying cylinder 12 will cover the bottom of the end cover after it descends. At this time, the correction circle 4 releases the end cover, and the telescopic device 49 starts to extend the clamping plate 50 inward to fix and clamp the lower half of the outer ring of the end cover. Then the conveying block 48 rises in the track 13 to transport the end cover to the top of the conveying cylinder 12. Then the second cylinder 10 rebounds to lift the end cover to the next area, so as to achieve the effect of automatic correction and upward transportation to the next designated area.

A rotating plate 23 is provided inside the grabbing cylinder 20, and a slide groove 24 is provided inside the rotating plate 23. The interior of the grabbing cylinder 20 is slidably connected to a fixed plate 26, and a plug 25 is provided on the top of the fixed plate 26. The plug 25 and the slide groove 24 are slidably connected to each other, and the push block 22 and the rotating plate 23 are rotatably connected to each other. The sliding bottom 15 drives the adapter plate 16 to reach the top of the conveying cylinder 12, and then the fourth cylinder 17 starts to push the gas rod downward, and drives the grabbing cylinder 20 to descend through the connecting column 18. Then the grabbing cylinder 20 will wrap the upper half of the outer ring of the end cover, and then the fifth cylinder 21 starts to push the internal gas rod, and the rotating plate 23 is driven to rotate through the push block 22. At this time, when the rotating plate 23 rotates, the plug 25 that is in sliding connection with its internal slide groove 24 will be driven by it to slide along the track of the slide groove 24.

Then the presser 19 will press the grabbing cylinder 20 downward through the pressing rod 52, so that the end cover and the motor core 33 are aligned. The grabbing cylinder 20 will make the end cover and the motor core 33 adsorbed through the magnetic attraction of the fixed plate 26, and then the presser 19 will unload the force. After losing the downward thrust of the presser 19, the fourth cylinder 17 will rebound the internal gas rod, so that the end cover drives the motor core 33 to leave the feeding platform 31, so as to achieve the effect of automatically grabbing the end cover and transporting it to the installation area and quickly and accurately installing its motor core 33.

[0034] A motor 27 is fixedly installed above the base 1, and the output end of the motor 27 is connected to the central shaft 28.

The positions are interchanged. When the presser 19 is pressed downward to drive the grabbing cylinder 20 to move downward, the grabbing cylinder 20 will push the detection ring 34 downward. The detection ring 34 is squeezed and moves downward on the feeding platform 31. At this time, the first connecting plate 35 and the second connecting plate 36 will be squeezed and compressed, so that the control block 53 at the center end moves outward, thereby pulling the internal pull rod 38. The clamping block 32 is subjected to the elastic force of the second spring 39 and will clamp the internal motor core 33 inward. At this time, the pull rod 38 pulls the clamping block 32 outward, so that the second spring 39 is compressed, thereby releasing the clamping of the motor core 33. After the motor core 33 is adsorbed away, the grabbing cylinder 20 rebounds upward, and the clamping block 32 will also rebound to return to its original position, achieving the effect of automatic clamping and loosening, cooperating with each other, and improving efficiency.
