[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0019] like Figures 1 to 4In the embodiment of the sheet Mylar feeding device for magnet assembly shown in the utility model, the sheet Mylar feeding device for magnet assembly includes a material rack 10 and a feeding rack 20, the sheet Mylar is stacked in the material rack 10, the feeding rack 20 is used to place a single sheet Mylar, and also includes a feeding robot 30 for sequentially transferring the sheet Mylar stacked in the material rack 10 to the feeding rack 20, the feeding robot 30 includes a column 31 and a beam 32, a linear motor 33 is installed on the beam 32, and the linear A feeding support 34 is installed on the sliding block of the motor 33, and a lifting slide 35 is installed on the feeding support 34. A lifting motor 36 for driving the lifting slide 35 to slide up and down in the vertical direction is also installed on the feeding support 34; a suction cup suspension 37 is provided on the lifting slide 35 on the side facing the material rack 10, and four feeding suction cups 38 are symmetrically installed on the lower side of the suction cup suspension 37, and each feeding suction cup 38 is connected to the air pump through an air pipe. When the air pump is pumping air, each feeding suction cup generates a negative pressure to absorb the sheet Mylar. The present application can evenly and reliably absorb the sheet Mylar by symmetrically installing four feeding suction cups on the lower side of the suction cup suspension, ensuring that the sheet Mylar does not fall during the feeding and transfer process, and has high reliability; the feeding robot arm adopts a linear motor and a lifting motor to realize the horizontal movement and up and down movement of the feeding suction cup, and the movement is stable during the material transfer process, and the reliability is good.

[0020] In one embodiment of the present application, preferably, two vertical slide grooves 341 are provided on the loading support 34, and the lifting slide plate 35 is provided with a vertical slide rail 351 passing through the vertical slide grooves 341, so that the lifting plate 35 can slide up and down reliably; preferably, limit columns 352 are also provided at the upper and lower ends of the vertical slide rail 351 to prevent the lifting slide plate from detaching from the loading support.

[0021] In one embodiment of the present application, preferably, a lifting rack 353 is provided on the lifting slide 35 in the vertical direction, and a driving gear meshing with the lifting rack 353 is provided on the output shaft of the lifting motor 36, so that the lifting motor 36 can drive the lifting slide to move up and down through the driving gear and the lifting rack.

[0022] In one embodiment of the present application, preferably, four material-blocking vertical plates 11 are provided on the material rack 10 to prevent the sheet Mylar from slipping; preferably, two vertical plates 12 are provided on the material rack 10 along the length direction of the sheet Mylar, and the top of the vertical plate 12 is provided with an elastic paddle 13 extending toward the inner side of the material rack 10. When the loading suction cup 38 on the lower side of the suction cup suspension 37 absorbs the sheet Mylar stacked on the material rack 10, the uppermost sheet Mylar is absorbed and moves upward with the lifting slide, and the edge of the elastic paddle 13 can scrape the edge of the sheet Mylar to prevent the sheet Mylar from sticking and being transferred simultaneously, thereby ensuring that the loading suction cup 38 only absorbs and transfers one sheet Mylar stacked on the uppermost side of the material rack each time.

[0023] In one embodiment of the present application, preferably, two through holes are provided on the top plate 21 of the loading rack 20, and positioning suction cups 22 with the opening facing upward are installed in the through holes, and the positioning suction cups 22 are used to absorb the sheet Mylar transferred to the top plate 21 from the bottom to prevent the sheet Mylar from moving; specifically, the positioning suction cups 22 are connected to the air pump through an air pipe, and the air pump draws air so that the positioning suction cups 22 generate negative pressure to absorb the sheet Mylar.
