DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figures 1 to 3As shown, in this embodiment, a fully automatic nut-punching mechanism includes an adapter plate 1, an adsorption plate 2, a nut stroke moving plate 3 and a mold plate 4. The two ends of the adapter plate 1 are respectively equipped with an adsorption cylinder 5 and a nut pushing cylinder 6. The adsorption plate 2 is installed on the driving end of the adsorption cylinder 5, and the nut stroke moving plate 3 is installed on the driving end of the nut pushing cylinder 6. A guide plate 7 is fixed to the lower end of the adapter plate 1, and guide pillars 8 are fixed around the mold plate 4. The guide pillars 8 pass through the guide plate 7. A push rod 9 is installed on the nut stroke moving plate 3, and a nut sleeve 10 is installed on the guide plate 7. The push rod 9 is inserted into the nut sleeve 10 from top to bottom. A sphere 11 and a ring 12 are provided at the lower end of the nut sleeve 10. The sphere 11 is elastically connected to the tube wall of the nut sleeve 10 laterally, and the ring 12 is sleeved on the outside of the sphere 11. A nut top column 13 is fixed on the mold plate 4, and the nut top column 13 is inserted into the nut sleeve 10 from bottom to top.

[0022] The adapter plate 1 is installed on the manipulator. The adsorption plate 2 on one side is controlled by the adsorption cylinder 5 to approach the product to suck the product into the mold, or take the product out of the mold for storage. The nut pushing cylinder 6 on the other side controls the nut stroke moving plate 3 to move up and down. When the manipulator is docked with the mold, the mold plate 4 on the mold is docked with the guide plate 7 through the guide column 8, so that the nut top column 13 on the mold plate 4 is inserted into the nut sleeve 10. The upper end of the nut top column 13 pushes the ball 11 outward, and the ring 12 expands outward, opening the internal space of the nut sleeve 10 blocked by the ball 11, and the nut can fall into the nut top column 13 to be received. When the nut top column 13 withdraws, the nut is taken away, and the ring 12 contracts, squeezing the ball 11 inward to limit the internal nut position. Then the nut stroke moving plate 3 moves downward under the action of the nut pushing cylinder 6, and the push rod 9 presses the nut against the position of the ball 11 to ensure that the next round of nut acquisition is carried out smoothly.

[0023] A plurality of suction nozzles 14 are installed at the lower end of the suction plate 2, and the suction nozzles 14 are used for adsorbing products.

[0024] Guide sleeves 15 are fixed around the guide plate 7, and the guide column 8 passes through the guide sleeve 15 and is slidably connected to the guide sleeve 15. When the guide plate 7 is close to the mold plate 4, in order to ensure that the nut sleeve 10 is aligned with the position of the nut top column 13, it is easy to remove the nut.

[0025] A fixed column 16 is connected between the guide plate 7 and the adapter plate 1. Under the action of the adapter plate 1, the manipulator controls the conversion of the adapter plate 1 to realize the adsorption of the product by the adsorption plate 2 on the mold plate 4, and the nut stroke moving plate 3 is aligned with the control nut on the mold plate 4.

[0026] A mounting groove is provided on the guide plate 7, and a clamping plate 17 is connected with a bolt in the mounting groove. A clamping groove 18 is provided on the nut sleeve 10, and the clamping plate 17 is clamped in the clamping groove 18. After all the nuts in the nut sleeve 10 are taken out, the clamping plate 17 can be loosened, the nut sleeve 10 can be replaced, and then the clamping plate 17 can be used to lock the clamping groove 18.

[0027] A collision prevention column 19 is also fixed to the lower end of the guide plate 7. When the guide plate 7 is combined with the mold plate 4, the collision prevention column 19 can prevent the guide plate 7 from getting too close to the mold plate 4, causing the nut top column 13 on the mold plate 4 to penetrate too deeply into the nut sleeve 10 on the guide plate 7.

[0028] The upper end of the nut sleeve 10 is arc-shaped, and the nut sleeve 10 is inserted into the guide plate 7 from bottom to top for fixation. The arc-shaped structure of the nut sleeve 10 facilitates replacement into the guide plate 7 from bottom to top.

[0029] An annular groove 20 is provided at the upper end of the nut top column 13 , and the sphere 11 is inserted into the annular groove 20 . The annular groove 20 limits the position of the sphere 11 , and the nut can be taken onto the nut top column 13 .

[0030] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
