The lighting device 14 is arranged on the machine body, and the lighting device 14 can make the pattern shooting of the button more clear.
[0028] The vibration feeding disc 10 is used to feed the button placed in it, and the feeding process is that the rear-end button pushes the front-end button to move forward along with vibration; the feeding slide 11 is connected with the discharge port of the vibration feeding disc 10, and the tail end of the feeding slide 11 has a discharging port 12; in working, the vibration feeding disc 10 is intermittent start-stop, specifically, when the button at the tail end of the feeding slide 11 is discharged, the feeding operation is stopped to avoid that the button in the feeding slide 11 continuously pushes the front-end button to discharge; when the discharged button is corrected by the button direction correction mechanism and enters the next process, and the material receiving mechanism returns, the vibration feeding disc 10 is started again to carry out the next discharging.
[0029] The pressing mechanism is used in cooperation with the feeding slide 11 to arrange the buttons in the feeding slide 11 in order; the pressing mechanism comprises a pressing rod 50, a pressing base 51 and an adjusting screw 52, the adjusting screw 52 is positioned on the machine body and is connected with the pressing base 51 and used to adjust the relative position of the pressing base 51 in the height direction; specifically, when the height needs to be adjusted, the adjusting screw 52 is rotated to make the threaded part of the adjusting screw 52 move downward or upward, and after the adjustment is completed, the end face of the pressing base 51 is abutted by the positioning stud in the positioning screw hole 511 on the pressing base 51 to achieve the locking effect. The pressing rod 50 is fixedly connected with the pressing base 51 and is located in the feeding slide 11 and forms a channel for the buttons to pass through with the feeding slide 11.
[0030] The blocking mechanism cooperates with the tail end of the feeding slide 11 to limit the buttons from sliding out of the tail end of the feeding slide 11; the blocking mechanism comprises a blocking base 60, a blocking cylinder 61, a blocking connecting rod 62 and a blocking rod 63, the blocking base 60 is fixed on the machine body, and the blocking cylinder 61 is arranged on the blocking base 60; one end of the blocking connecting rod is connected with the cylinder rod of the blocking cylinder 61, and the other end is fixedly connected with the blocking rod 63. In work, the blocking cylinder 61 can push the blocking rod 63 to move, so that it cooperates with the tail of the feeding slide 11 to block the buttons in the feeding slide 11 from sliding out of the tail end.
[0031] The pushing seat 31 is connected to the feeding cylinder 30, and the receiving mechanism is arranged on the pushing seat 31. The receiving mechanism comprises a receiving connecting rod 22, a receiving disc 20, a receiving rod 21, a sliding piece 23, a rotating device and a lifting device. The receiving disc 20 is fixed to the end of the receiving connecting rod 22 and is located directly below the material falling port 11. The receiving rod 21 is vertically arranged on the receiving disc 20, and the number of the receiving rod 21 is the same as the number of the through holes of the button. The receiving rod 21 is used to be inserted into the through hole of the button. The pushing seat 31 has a guide rail 32. The lifting device is slidably arranged on the guide rail 32 through the sliding piece 23. The sliding piece 23 is composed of a lifting sliding block 231 and a connecting piece 232.

In the working process, after the receiving disc 20 receives the button, the feeding cylinder 30 pushes the pushing seat 31 to move the whole receiving mechanism, so that the receiving disc 20 is moved to the image recognition mechanism 13 to perform image recognition. When the direction of the button needs to be corrected, the lifting cylinder 33 drives the lifting sliding block 231 to move, so that the material grabbing mechanism grabs the button. After the direction of the button is changed, the receiving disc 20 receives the button from the material grabbing mechanism and drives the rotating cylinder 34 to rotate the rotating block 35, so that the receiving connecting rod 22 is driven by the pivot 36 to rotate to the next workbench to drop the button.

One end of the correction rod 61 is connected to the lifting rotating motor 60. The other end of the correction rod 61 is matched with the receiving rod 21 to correct the hole position of the button. In the working process, when the hole position of the button is deviated from the position of the receiving rod 21, the correction rod 61 is first contacted with the button under the driving of the lifting rotating motor 60, and then the button is slowly rotated until the hole position of the button is opposite to the receiving rod 21.
[0033] The camera recognition mechanism 13 is used to recognize the pattern on the button and feed it back to the numerical control system. The camera recognition mechanism 13 has a camera which can take a picture of the pattern on the button and upload it to the numerical control system for identification. According to the identification result, each mechanism performs corresponding action. Specifically, when the results are consistent, the material receiving mechanism performs the unloading operation; when the results are different, the button direction correction mechanism corrects the direction of the button according to the required rotation angle.

The material grabbing mechanism includes the mechanical gripper 40 and a finger cylinder 41 which can control the mechanical gripper 40 to perform the opening operation so as to grab and drop the button.
[0035] The button direction correction mechanism is connected with the material grabbing mechanism and corrects the direction of the button by controlling the rotation of the material grabbing mechanism. The button direction correction mechanism includes a push cylinder 70, a push seat 71, a correction motor 72, a linkage seat 73, a correction belt 74, a main pulley 75 and a slave pulley 76. One end of the push seat 71 is connected with the push cylinder 70 and the other end is connected with the linkage seat 73.
