Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] First embodiment Please refer to in combination with Figures 1 - 6, in the first embodiment of the present invention, the vision inspection machine includes: a vision inspection machine body 1. A detection chamber 101 is arranged inside the vision inspection machine body 1. A detection camera 2 and two fill light lamps 3 are installed inside the detection chamber 101. A fixing plate 4 is fixedly installed on the bottom inner wall of the detection chamber 101. Two shaft seats 5 are fixedly installed on the fixing plate 4. The same rotating shaft 6 is rotatably installed on the two shaft seats 5. A plurality of connecting blocks 7 are fixedly sleeved on the rotating shaft 6. The same mounting frame is fixedly installed on the plurality of connecting blocks 7. The mounting frame includes two C-shaped boxes 8 and a connecting component. The connecting component is installed on the tops of the two C-shaped boxes 8. The C-shaped box 8 close to the fixing plate 4 is fixedly connected to three connecting blocks 7. A first rotating shaft 9 and a second rotating shaft 10 are rotatably installed inside each of the two C-shaped boxes 8. The first rotating shaft 9 and the second rotating shaft 10 are respectively located at both ends of the C-shaped box 8. Both ends of the first rotating shaft 9 and the second rotating shaft 10 extend outside the C-shaped box 8. Pulley wheels 11 are fixedly sleeved on both the first rotating shaft 9 and the second rotating shaft 10. The same thickened rubber belt 12 is sleeved on the corresponding two pulley wheels 11. The minimum distance between the two thickened rubber belts 12 is smaller than the outer diameter of the bottleneck of the bottle to be detected. In this way, when the bottle is brought into the two thickened rubber belts 12, it will be clamped by the two thickened rubber belts 12. Electric motors 13 are fixedly installed on the tops of both C-shaped boxes 8. Both electric motors 13 are in transmission connection with the corresponding first rotating shaft 9. Specifically, a first bevel gear 14 is fixedly sleeved on the output end of the electric motor 13. A second bevel gear 15 is fixedly sleeved on the top end of the first rotating shaft 9. The first bevel gear 14 and the second bevel gear 15 are meshed with each other. During operation, only one electric motor 13 is started to drive the corresponding thickened rubber belt 12 to rotate, and the other thickened rubber belt 12 does not rotate. Driven by the rotating thickened rubber belt 12, the bottle rotates and moves. Two groove boxes 17 are fixedly installed on the fixing plate 4. Two inclined support rods are fixedly installed at the bottom of the groove box 17. The bottom ends of the two inclined support rods are fixedly connected to the fixing plate 4. Rack bars 18 are slidably installed inside both groove boxes 17. Gear wheels 16 are fixedly sleeved on both ends of the rotating shaft 6. The two rack bars 18 are respectively meshed with the two gear wheels 16. Electric push rods 19 are fixedly installed at the bottoms of both groove boxes 17. Fixed bars 20 are fixedly installed at the bottoms of the two rack bars 18. The bottom ends of the two fixed bars 20 extend below the corresponding groove boxes 17 and are fixedly connected to the connection heads of the corresponding electric push rods 19. Avoidance strip openings are formed on the bottom inner walls of the groove boxes 17. The fixed bars 20 penetrate through the avoidance strip openings and are movably connected to the inner walls of the avoidance strip openings. The electric push rods 19 drive the rack bars 18 to move forward (in the direction away from the fixing plate 4) through the fixed bars 20. The rack bars 18 drive the gear wheels 16 to rotate clockwise, and then the rotating shaft 6 rotates clockwise. The rotating shaft 6 drives the mounting frame to rotate correspondingly through a plurality of connecting blocks 7. In this way, the bottom of the bottle to be detected can be lifted, and the detection camera 2 can detect the anti-counterfeiting mark, production date, etc. of the bottle bottom.

[0021] In this embodiment, in order to improve the reliability of the thickened rubber belt 12 for clamping the bottle to be detected, a support plate is fixedly installed in the C-shaped box 8. The support plate is located inside the thickened rubber belt 12 and is in contact with the thickened rubber belt 12.

[0022] In this embodiment, the connection assembly specifically includes two connecting plates 21. The two ends of the two connecting plates 21 are respectively fixedly connected to the tops of the two C-shaped boxes 8 by bolts.

[0023] In this embodiment: During use, the vision inspection machine is placed between the feeding conveyor belt and the discharging conveyor belt. The tail end of the feeding conveyor belt extends into the inspection chamber 101 from one side, and the head end of the discharging conveyor belt extends into the inspection chamber 101 from the other side. The bottle to be detected enters the inspection chamber 101 under the conveyance of the feeding conveyor belt, and then enters between the two thickened rubber belts 12. At this time, the inspection camera 2 starts to scan and detect the bottle body. One of the electric motors 13 operates normally, and the other electric motor 13 is turned off normally. The operating electric motor 13 drives the corresponding first rotating shaft 9 to rotate, and the first rotating shaft 9 drives the pulley 11 on itself to rotate. In this way, the corresponding thickened rubber belt 12 can be rotated, while the other thickened rubber belt 12 remains stationary. Therefore, the bottle will move towards the discharging conveyor belt while rotating under the push of the rotating thickened rubber belt 12. Since the bottle moves forward while rotating, the inspection camera 2 can scan all the contents of the labels and stickers on the bottle body, and thus transmit the collected relevant images to the image processing device. After the bottle to be detected enters the middle position between the two thickened rubber belts 12, the telescopic rods of the two electric push rods 19 contract simultaneously. The two electric push rods 19 drive the two racks 18 to move forward. Driven by the two racks 18, the two gears 16 will rotate clockwise, and then the rotating shaft 6 will rotate clockwise. Driven by the rotating shaft 6, the mounting frame rotates clockwise. The bottle to be detected rotates along with the mounting frame during the process of moving forward while rotating. When it rotates to 60° - 90°, the inspection camera 2 can scan the anti-counterfeiting mark, production date, etc. on the bottom of the bottle, and thus transmit the collected relevant images to the image processing device. After the scanning of the bottom of the bottle is completed, the telescopic shafts of the two electric push rods 19 extend outwards, pushing the two racks 18 to move backward. It can be known from the reverse reasoning of the above working principle that the rotating shaft 6 will rotate counterclockwise, so that the mounting frame gradually returns downward. Along with the continuous movement of the bottle, after the mounting frame settles down, the bottle falls onto the discharging conveyor belt. Finally, the bottle leaves the two thickened rubber belts 12 and is transported out by the discharging conveyor belt. Since only one thickened rubber belt 12 is needed to complete the rotational movement of the bottle, the other thickened rubber belt 12 serves as a backup. That is, when one of the electric motors 13 or the transmission components fails, the other electric motor 13 can be used to drive the corresponding thickened rubber belt 12 to work.

[0024] Compared with the related art, the vision inspection machine provided by the present invention has the following beneficial effects: Through the arrangement of components such as the fixing plate 4, two shaft seats 5, the rotating shaft 6, two C-shaped boxes 8, two first rotating shafts 9, two second rotating shafts 10, two belt pulleys 11, two thickened rubber belts 12, two electric motors 13, etc., after starting one of the electric motors 13, the corresponding thickened rubber belt 12 can be driven to rotate, which can cooperate with the other non-rotating thickened rubber belt 12 to drive the bottle to be detected to rotate and move in the direction of the discharge conveyor belt, so that the inspection camera 2 can scan all the contents of the labels and stickers on the bottle body. It has the advantage of comprehensive detection and only a single inspection camera is used; through the arrangement of components such as two gears 16, two groove boxes 17, two racks 18, two electric push rods 19, two fixing bars 20, etc., during the process of retracting the telescopic rods of the two electric push rods 19, the rotating shaft 6 can be rotated clockwise, and then components such as the two C-shaped boxes 8 and the two thickened rubber belts 12 can be rotated clockwise. In this way, the bottle after the bottle body is scanned can be rotated clockwise by a certain angle, so that the inspection camera 2 can scan the anti-counterfeiting marks, production dates, etc. on the bottle bottom, further increasing the comprehensiveness of the detection of this vision inspection machine.

[0025] Second Embodiment: The second embodiment of the present invention will be further described below in conjunction with the drawings and embodiments.

[0026] Please refer to Figures 7 - 9, in the vision detector proposed in this embodiment, groove blocks 22 are fixedly installed at the tops of the two second rotating shafts 10. An octagonal slot 2201 is formed at the top of the groove block 22. A fixing rod 23 is fixedly installed at the top of one of the C-shaped boxes 8. A collar 24 is movably sleeved on the fixing rod 23. The inner diameter of the collar 24 is the same as the diameter of the fixing rod 23. The collar 24 can slide relative to the fixing rod 23 or rotate relative to the fixing rod 23. An outer sleeve 25 is fixedly installed on the outer wall of the collar 24. An inner sliding rod 26 is slidably installed in the outer sleeve 25. The outer sleeve 25 and the inner sliding rod 26 form a telescopic rod. One end of the inner sliding rod 26 away from the fixing rod 23 is fixedly installed with an octagonal insert 27. The bottom end of the octagonal insert 27 extends into one of the octagonal slots 2201. Through the above settings, after determining the thickened rubber belt 12 to be operated, the octagonal insert 27 is inserted into the octagonal slot 2201 corresponding to the other thickened rubber belt 12. In this way, the corresponding second rotating shaft 10 can be locked, so that the resistance of the non-operating thickened rubber belt 12 to rotate can be effectively increased, making it not easy to rotate. In order to make the octagonal insert 27 more smoothly inserted into the octagonal slot 2201, the connection between the bottom end of the octagonal insert 27 and the adjacent outer wall is designed with a rounded corner.

[0027] In this embodiment, in order to make the octagonal insert 27 reliably located in the octagonal slot 2201, a first end plate 28 is fixedly installed at the top end of the fixing rod 23. A first spring 29 sleeved on the fixing rod 23 is fixedly installed at the bottom of the first end plate 28. A balance washer is slidably sleeved on the fixing rod 23. The bottom end of the first spring 29 is fixedly connected to the balance washer. The bottom of the balance washer is in contact with the top of the collar 24.

[0028] In this embodiment: After determining the thickened rubber belt 12 for operation, another thickened rubber belt 12 is restricted to prevent it from rotating under the frictional force of the bottle, which may otherwise cause the bottle to only move without rotating. For example, when selecting the thickened rubber belt 12 away from the fixed plate 4 as the operating belt, the octagonal insert block 27 is inserted into the octagonal slot 2201 in the slot block 22 near the fixed plate 4. When inserting, first lift the outer sleeve 25 upward (during this process, the first spring 29 will be compressed), then rotate the outer sleeve 25 so that the octagonal insert block 27 faces the target slot block 22. After that, pull out the inner sliding rod 26 outward by a certain amount so that the octagonal insert block 27 is located above the target slot block 22. Then release the outer sleeve 25 to insert the octagonal insert block 27 into the octagonal slot 2201 in the target slot block 22. If the octagonal insert block 27 cannot be exactly aligned with the octagonal slot 2201, the relevant personnel can manually push the corresponding thickened rubber belt 12 a certain distance. Driven by the thickened rubber belt 12, the corresponding second rotating shaft 10 will rotate by a certain angle, so that the slot block 22 and the octagonal insert block 27 can be adjusted to alignment, enabling the octagonal insert block 27 to be inserted into the corresponding octagonal slot 2201. In this way, the second rotating shaft 10 near the fixed plate 4 is locked, and the pulley 11 on it cannot rotate. When the mounting frame rotates clockwise, due to the resisting and restricting effect of the first spring 29 on the collar 24, the outer sleeve 25 will not automatically approach the first end plate 28, that is, the octagonal insert block 27 can still be located in the octagonal slot 2201. In this case, if the corresponding thickened rubber belt 12 needs to rotate, it needs to overcome a large sliding frictional force, effectively preventing it from rotating under the frictional force of the bottle, and then ensuring that the bottle can reliably rotate and move towards the direction of the discharge conveyor belt, enabling the inspection camera 2 to fully scan the content of the label and sticker on the bottle body, improving the reliability of the use of this vision inspection machine.

[0029] Third Embodiment: The following further describes the third embodiment of the present invention in conjunction with the drawings and embodiments.

[0030] Please refer to Figures 10 - 13, in the vision detector proposed in this embodiment, the connecting component has another structure. Under this structure of the connecting component, the distance between the two C-shaped boxes 8 can be adjusted. The connecting component specifically includes two first guiding slide bars 30, two sliding connection blocks 31, a lead screw 32, a fixed strip plate 33 and a driven block 34. Both of the two first guiding slide bars 30 are fixedly installed on the top of the C-shaped box 8 close to the fixed plate 4. Both of the two sliding connection blocks 31 and the driven block 34 are fixedly installed on the top of the C-shaped box 8 far from the fixed plate 4. The driven block 34 is located between the two sliding connection blocks 31. Both of the two first guiding slide bars 30 penetrate through the corresponding sliding connection blocks 31 and are slidably connected to the corresponding sliding connection blocks 31. The lead screw 32 is rotatably installed on the top of the C-shaped box 8 close to the fixed plate 4. The lead screw 32 penetrates through the driven block 34 and is threadedly connected to the driven block 34. The fixed strip plate 33 is fixedly installed at one end of the two first guiding slide bars 30 far from the fixed plate 4. The lead screw 32 penetrates through the fixed strip plate 33 and is rotatably connected to the fixed strip plate 33. In order to facilitate the rotation of the lead screw 32, a hexagonal block 35 is fixedly installed at one end of the lead screw 32 far from the fixed plate 4. A hexagonal groove is formed in the hexagonal block 35. The lead screw 32 can be rotated by clamping the hexagonal block 35 with a wrench. At the same time, due to the formation of the hexagonal groove, relevant users can also use an internal hexagonal wrench to rotate the lead screw 32. When the lead screw 32 rotates forward or backward, it will drive the driven block 34 to move backward or forward, and the driven block 34 drives the C-shaped box 8 connected thereto to move, so that the minimum distance between the two thickened rubber belts 12 can be adjusted to be larger or smaller.

[0031] In this embodiment, in order to lock the lead screw 32 and prevent the distance between the two C-shaped boxes 8 from changing, a plurality of tooth blocks 36 distributed in a circular array are fixedly installed on the outer wall of the lead screw 32. A locking mechanism is installed on the fixed strip plate 33. The locking mechanism is used to cooperate with the plurality of tooth blocks 36 to lock the lead screw 32. More specifically, the locking mechanism includes two second guiding slide bars 37, a second end plate 38, a sliding sleeve plate 39, an arc-shaped block 40, a plurality of teeth 41 and two second springs 42. Both of the two second guiding slide bars 37 are fixedly installed on the outer wall of the fixed strip plate 33 far from the fixed plate 4. The second end plate 38 is fixedly installed at one end of the two second guiding slide bars 37 far from the fixed strip plate 33. The sliding sleeve plate 39 is slidably sleeved on the two second guiding slide bars 37. A hand rod is fixedly installed on the top of the sliding sleeve plate 39. The sliding sleeve plate 39 can be pulled through the hand rod. The arc-shaped block 40 is fixedly installed at one end of the sliding sleeve plate 39 close to the lead screw 32. A plurality of teeth 41 are fixedly installed in the arc-shaped block 40. A clamping groove is formed between any two adjacent tooth blocks 36. The size of the clamping groove is adapted to the teeth 41. A plurality of teeth 41 are all located in the clamping groove between the corresponding two tooth blocks 36.

[0032] In this embodiment: Pull the sliding sleeve plate 39 forward through the hand lever. The sliding sleeve plate 39 will drive the arc-shaped block 40 to move. The arc-shaped block 40 will drive multiple teeth 41 on itself to move. Eventually, multiple teeth 41 can be withdrawn from the corresponding positioning slots, so that the locking of the lead screw 32 can be released. During the above process, both of the two second springs 42 will be compressed. Without the sliding sleeve plate 39 resetting, a wrench or an Allen wrench can be used subsequently to rotate the lead screw 32. When the lead screw 32 rotates forward, it will drive the driven block 34 to move backward. The driven block 34 will drive the C-shaped box 8 at the front side to move, so that the distance between the two thickened rubber belts 12 becomes smaller. On the contrary, when the lead screw 32 rotates reversely, the distance between the two thickened rubber belts 12 will become larger. After the adjustment is completed, release the sliding sleeve plate 39. Under the action of the two second springs 42, the sliding sleeve plate 39 will move backward for resetting. The sliding sleeve plate 39 will drive the arc-shaped block 40 and multiple teeth 41 to move backward, so that multiple teeth 41 will re-engage into the currently corresponding positioning slots. If the teeth 41 come into contact with the tooth block 36, just slightly turn the lead screw 32. After the teeth 41 are completely axially aligned with the corresponding positioning slots, under the elastic force of the second spring 42, they will automatically engage into the positioning slots. Under the clamping action of multiple teeth 41, the lead screw 32 cannot rotate circumferentially. Therefore, the distance between the two thickened rubber belts 12 can also be reliably maintained. Relevant users can adjust the minimum distance between the two thickened rubber belts 12 according to the outer diameter of the bottleneck of the bottle to be detected, which has the advantage of a wide application range.

[0033] The above are only embodiments of the present invention and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
