Description

Technical Field

[0002] The motor has a stator and a rotor inside, which are important motor parts. The stator and the rotor both have an iron core. At present, the iron core is generally made of stacked silicon steel sheets. For the processing and manufacturing of silicon steel sheets, punching and cutting are generally used, that is, the product is punched out from the coil by a punching die, and then stacked together. There are many stacking methods at present, and welding, glue bonding, riveting, etc. are commonly used; when punching the product, generally multiple steps are performed, that is, in the previous step, according to the product structure, the unnecessary waste is punched out, and finally the product is obtained; and the existing equipment does not effectively organize the punched products, resulting in high intensity of subsequent manual sorting. On the other hand, for the punched products, directly stacking will cause wear defects of the punching die, resulting in errors in product size and inability to align when stacking.

Specifically, the measuring instrument 36 includes a length sensor and a contact. When the contact contacts the detection area, the contact moves in the detection area to generate telescopic movement, and the length sensor transmits feedback detection information).

[0027] The principle of implementing the present invention is as follows: the coil is transported on the die table 7, and the die oil cylinder 1 8 and the die electric cylinder 2 9 work, so that the mold 1 801 and the mold 2 901 perform a die operation on the coil to punch the product from the coil; specifically, in terms of processing sequence, the internal circular area of ​​the product is first punched by the mold 1 801, that is, the separated circular material enters the stacking tube 2 11 and is supported by the support table 1 18; under continuous operation, it can be stacked inside the stacking tube 2 11; further, before the operation, the transmission box 3 transmits the adhesive glue, which is sprayed on the coil by the spraying part 4, and under the die operation, the product is stacked inside the limit ring 19 and supported by the support table 2 41, and further, the products are stacked by mutual adhesion through the adhesive glue.

[0028] When stacking, the height of the gear ring 31 can be controlled by the lifting electric cylinder three 40, and the height of the support rod 42 can be controlled by the lifting electric cylinder two 39. The height can be adjusted according to the number of stacking layers. When the products are stacked, the support rod 42 is located on the inside to support and fix the products. Specifically, when the products are stacked, the motor 15 works, and under the gear transmission, the support control gear ring 37 rotates, and under the connecting action of the connecting rod 38, the lifting electric cylinder two 39 moves radially, that is, after the product moves downward and is stacked, the support rod 42 is supported and fixed on the inside of the product through radial movement, so as to avoid contact friction between the product and the support rod 42.

[0029] After completing stacking on one side, the stacked products are transferred to the inspection area according to the stacking height, that is, the products are located on the inner side of the detection piece. Specifically, by controlling the gear 30 to work, the control gear ring 31 is rotated under the gear transmission, and then the detection gear 34 is active, so that the measuring instrument 36 moves toward the product, that is, contacts with the outer side of the product. According to different contact areas, the corresponding radial sliding distances of the measuring instrument 36 are different, that is, in this embodiment, there are convex areas and concave areas on the outer side of the product, and the measuring instruments 36 in the corresponding directions move radially and contact with the convex areas and concave areas; the measuring instrument 36 contacts the detection area to complete the size detection (through the telescopic movement of the contact, the length sensor outputs feedback detection information), and further, by supporting the control gear ring 37 to work, under the gear transmission, the detection rotating frame 12 and the detection rotating frame 2 1201 rotate, and the measuring instrument 36 moves in the detection area, so as to complete the size detection of different contact areas; if the size error is detected to be outside the required range, it does not meet the product quality standard, and the work can be stopped, and the punch die is inspected and maintained in time to avoid the defective products from being processed and stacked, causing waste.

[0030] After completing an operation, the screw motor 5 works to rotate the screw 6, move the slide 14, and control the lifting electric cylinder 13 to control the support platform 18 to separate from the stacking tube 2 11, and the lifting electric cylinder 3 40 controls the support platform 2 41 to separate from the stacking tube 10, and the lifting electric cylinder 2 39 controls the support rod 42 to also separate from the stacking tube 10, so as to transfer the product; the circular material supported by the support platform 18 is also in a stacked state, avoiding scattered stacking (the circular material is waste, and it falls directly after punching, and no effective sorting is taken, and the subsequent manual sorting is time-consuming and labor-intensive).

[0031] During transfer, the support table 18 moves to the inner side of the limit ring 19, and moves through the electromagnetic fixing shaft 20 and cooperates with the fixing hole 1801 to fix the limit ring 19; further, the electromagnetic adsorption part 26 adsorbs the magnetic adsorption part 25, so that the buckle plate 23 moves and disengages from the buckle seat 22, so that the limit rod 21 is separated from the bottom of the stacking tube 2 11, so as to limit the circular material and prevent it from falling during the transfer process.
