[0020] Referring to Figures 1 - 5 , a front and back screening system for a cup lid, comprising a base 1. A vibrating disk main body 2 is fixedly connected to the upper end of the base 1. A vibrating disk is an auxiliary feeding device for an automatic assembly or automatic processing machine, simply referred to as a component feeding device. It can automatically arrange disordered workpieces neatly and convey them to the next process in a predetermined direction and order. It is an indispensable part of an industrial automation production line. A vibrating track 3 is arranged inside the vibrating disk main body 2. An outlet edge 4 is fixedly connected to the upper end of the vibrating disk main body 2. An outlet track 5 is fixedly connected to the right side of the outlet edge 4; As an implementation manner of the present invention, it further comprises a screening mechanism. The screening mechanism includes a cross plate 6 installed at the upper end of the outlet edge 4. A vision inspection instrument main body 29 is installed at the lower end of the cross plate 6. The vision inspection instrument main body 29 is used for screening the front and back sides of the cup lid. When the vision inspection instrument main body 29 is in use, it is used to check the front and back sides of the cup lid. Since there is a pattern on the front side of the cup lid, the front and back sides can be judged according to whether there is a pattern. When the detected side is the front side, the subsequent triggering mechanism can be driven to operate to achieve the triggering operation; As an implementation manner of the present invention, it further comprises a triggering mechanism. The triggering mechanism cooperates with the screening mechanism. The triggering mechanism includes a connecting column 7 horizontally penetrating. A rectangular block 13 is fixedly connected to the left side of the connecting column 7. A rectangular cavity 26 is arranged inside the rectangular block 13. A magnetic sliding plate 24 that can slide left and right is arranged inside the rectangular cavity 26. A strip-shaped opening 14 is opened on the front side of the rectangular cavity 26. A connecting rod 18 is fixedly connected to the front side of the magnetic sliding plate 24. A guiding column 15 is fixedly connected to the front end of the connecting rod 18. The right end of the guiding column 15 penetrates the outlet edge 4 and is fixedly connected to an abutting frame 16. An electromagnet 22 is fixedly connected to the left inner wall of the rectangular cavity 26. The electromagnet 22 is elastically connected to the magnetic sliding plate 24 through a second spring 23. The magnetic sliding plate 24 has magnetism. After the electromagnet 22 is powered on, the adjacent surfaces with the magnetic sliding plate 24 repel each other with the same polarity. The electromagnet 22 is electrically connected to the vision inspection instrument main body 29; As an implementation manner of the present invention, it further includes a heat dissipation and dust removal mechanism. The heat dissipation and dust removal mechanism is used to dissipate heat from the vision detector main body 29, and at the same time blow away the dust on the surface of its lens to ensure the accuracy of detection. The heat dissipation and dust removal mechanism includes a columnar cavity 27 opened inside the connecting column 7. The columnar cavity 27 is communicated with the rectangular cavity 26. A piston plate 28 that can slide left and right is arranged in the columnar cavity 27. The left side of the piston plate 28 is fixedly connected to a magnetic sliding plate 24 through a connecting rod 25. The right side space of the columnar cavity 27 is communicated with a first one-way pipe 10 and a second one-way pipe 11. The other end of the first one-way pipe 10 is communicated with the inside of the vision detector main body 29. A hollow ring 31 is installed at the lens of the vision detector main body 29. A plurality of fine holes 32 are opened inside the hollow ring 31. The vision detector main body 29 and the hollow ring 31 are communicated through a second connecting pipe 30; As an implementation manner of the present invention, the right side space of the columnar cavity 27 is communicated with a first one-way pipe 10 and a second one-way pipe 11. The other end of the first one-way pipe 10 is communicated with the inside of the vision detector main body 29. A hollow ring 31 is installed at the lens of the vision detector main body 29. A plurality of fine holes 32 are opened inside the hollow ring 31. The vision detector main body 29 and the hollow ring 31 are communicated through a second connecting pipe 30. A first one-way valve 21 is installed inside the first one-way pipe 10, and a second one-way valve 12 is installed inside the second one-way pipe 11. The flow direction of the first one-way valve 21 is from the right side space of the columnar cavity 27 to enter the inside of the vision detector main body 29 unidirectionally. The flow direction of the second one-way valve 12 is from the top space inside the filter box 8 to enter the right side space of the columnar cavity 27 unidirectionally. A collection box 33 is installed at the inner bottom of the filter box 8. A sealing door 9 is installed on the front side of the filter box 8. The sealing door 9 is used to process the collection box 33.

[0021] In the present invention, when the system is started, the vibration disk main body 2 starts to work, automatically arranges the disordered cup lids neatly through the vibration track 3 inside it, and conveys them to the discharge edge 4 in a predetermined direction and order; When the cup lid slides along the discharge edge 4 to below the cross plate 6, the vision detector main body 29 is started to detect the front and back sides of the cup lid. Since the front side of the cup lid usually has a pattern, the vision detector main body 29 judges the front and back sides of the cup lid by identifying the presence or absence of the pattern; When the vision detector main body 29 detects a front-side cup lid, it sends a signal to the electromagnet 22 to make it energized. Since the adjacent surfaces of the electromagnet 22 and the magnetic sliding plate 24 repel each other with the same polarity, the magnetic sliding plate 24 slides to the right under the action of the electromagnetic force, drives the connecting rod 18, the guiding column 15 and the pushing frame 16 to move to the right. The pushing frame 16 will push the cup lid to re-enter the vibration disk main body 2 for re-feeding operation to realize the front and back side screening; During the rightward sliding of the magnetic slide 24, the piston plate 28 is driven to move rightward in the columnar cavity 27 through the connecting rod 25. This action causes the air pressure in the right space of the columnar cavity 27 to increase, and the gas enters the interior of the vision detector main body 29 through the first one-way tube 10 (the first one-way valve 21 ensures the one-way flow of the gas) to dissipate heat from it.

[0022] Meanwhile, the gas in the vision detector main body 29 is extruded and enters the hollow ring 31 through the second connecting tube 30, and is ejected from multiple fine holes 32 on the inner side of the hollow ring 31 to blow dust on the lens surface of the vision detector main body 29, ensuring the cleanliness of the lens and improving the detection accuracy.

[0023] After the front cup cover is processed, the electromagnet 22 is powered off, and the magnetic slide 24 is reset to the left under the elastic force of the second spring 23. At this time, the piston plate 28 moves leftward in the columnar cavity 27, resulting in a decrease in the air pressure in the right space of the columnar cavity 27. The air at the hollow ring 31 will pass through the second one-way tube 11 after being filtered by the filter box 8 and enter the right space of the columnar cavity 27 to supplement the air pressure. During this process, dust and other impurities that have just been blown up are captured by the filter medium in the filter box 8 and finally fall into the collection box 33. When the dust in the collection box 33 accumulates to a certain extent, the collection box 33 can be cleaned by opening the sealing door 9. By using this method, the situation of secondary dust adhesion can be avoided; Furthermore, by using the first spring 20, during the air extraction operation, due to the upward air flow generated in the filter box 8, the air resistance will drive the filter net 19 to move upward and compress the first spring 20. After the subsequent air flow disappears, under the elastic action of the first spring 20 and the inertial action of the filter net 19, the filter net 19 will vibrate multiple times and finally stop moving. This vibration can achieve self-cleaning of the filter net 19 and prevent excessive dust from adhering to its lower part, which may affect subsequent use.

[0024] The above description is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
