[0022] Example 1, as Figure 1-5As shown, the borosilicate medical glass tube surface defect scanning and detection device includes a frame 1. A conveying device 4 is provided on one side of the frame 1. The conveying device 4 consists of a conveyor frame, a rotating roller, a conveyor belt sleeved on the outside of the rotating roller, and a drive motor for driving the rotating roller. A guide rod 8 is fixedly connected to one side of the conveyor frame of the conveying device 4. A housing 5 is provided on one side of the frame 1. Several industrial cameras 6 are installed inside the frame 1. An LED light 7 is installed at the top of the inner wall of the frame 1. An auxiliary device 2 is provided on one side of the conveying device 4. The auxiliary device 2 includes a guide plate 21. One side of the guide plate 21 is fixedly connected to one side of the conveyor frame of the conveying device 4. A collection box 22 is installed on one side of the guide plate 21 by means of a convenient device 3. The top of the guide plate 21 is fixedly connected to... There are two round rods 23. A protruding rod 24 is fixedly connected to the outer surface of each round rod 23. A first coil spring 25 is provided at the bottom end of each round rod 23. The two ends of the first coil spring 25 are fixedly connected to one side of the rotating shaft 34 and the bottom end of the guide plate 21, respectively. Sliding rings 26 are respectively fitted onto the outer surface of the two round rods 23. A through groove 27 is opened on the outer surface of the sliding ring 26. A spring 28 is provided at the bottom end of the sliding ring 26. A washer 29 is provided at the bottom end of the spring 28. The washer 29 is fitted onto the outside of the round rod 23. The bottom end of the washer 29 is fixedly connected to the top end of the guide plate 21. The upper and lower ends of the spring 28 are fixedly connected to the bottom end of the sliding ring 26 and the top end of the washer 29, respectively. A stop rod 210 is fixedly connected to the side of the two sliding rings 26 that is close to each other. When using a detection device to inspect the surface of borosilicate medical glass tubes, the guide plate 21 is first rotated on both sides of the top of the guide plate 21, causing the first coil spring 25 to deform and align the position of the protrusion 24 on the outer surface of the round rod 23 with the position of the through groove 27 on the outer surface of the sliding ring 26. Then, the sliding ring 26 on the outer surface of the two round rods 23 is pulled upward to move the sliding ring 26 above the protrusion 24, raising the stop bar 210. Releasing the first coil spring 25 of the round rod 23 and restoring it to its original state will cause the round rod 23 to rotate in the original direction, causing the through groove 27 on the outer surface of the sliding ring 26 to be misaligned with the position of the protrusion 24 on the outer surface of the round rod 23, fixing the sliding ring 26 above the protrusion 24. Finally, the terminal operating device is connected to the chassis 5 on one side of the frame 1. Next, the control box on the outer surface of the frame 1 controls the operation of the conveyor device 4 and turns on the LED light 7 and industrial camera 6. Then, the glass tube is placed vertically on the conveyor belt of the conveyor frame away from the auxiliary device 2. The drive motor on one side of the conveyor frame drives the rotating roller to move the conveyor belt, which transports the glass tube to the industrial camera 6. The LED light 7 illuminates the glass tube, and the industrial camera 6 takes a picture. The captured image is compared with the image information stored in the server of the chassis 5. If there is a defect on the surface of the glass tube, the LED light 7 is controlled to change color and the conveyor belt is stopped, making it easier for personnel to remove the defective product. After passing under the industrial camera 6, the glass tube moves towards the guide rod 8.The glass tubes are blocked by the guide rod 8 and enter the guide plate 21 along the surface of the guide rod 8. Then, they enter the collection box 22 through the guide plate 21. When the collection box 22 is almost full, the round rods 23 on both sides of the top of the guide plate 21 are pushed to rotate, causing the first coil spring 25 to deform. At this time, the stretched spring 28 returns to its original shape and pulls the two sliding rings 26 downward, so that the bottom end of the stop rod 210 rests on the outer surface of the guide plate 21 to block the gap between the guide plate 21 and the collection box 22. At this time, the collection box 22 can be removed through the convenient device 3. The glass tubes that have entered the guide plate 21 will stay inside the guide plate 21 for a short time. During this time, the glass tubes inside the collection box 22 can be removed or a new collection box can be replaced. 22. After the collection box 22 is replaced, the sliding ring 26 is moved to a position above the protruding rod 24, raising the stop rod 210. This allows the glass tubes on the outer surface of the guide plate 21 to enter the collection box 22 normally. By setting the auxiliary device 2, and installing the guide plate 21 and collection box 22 on one side of the conveying device 4, the glass tubes after testing will pass through the surface of the guide plate 21 into the collection box 22 for storage. When the collection box 22 is almost full, the stop rod 210 can be used to separate the guide plate 21 from the collection box 22, temporarily keeping the glass tubes on the outer surface of the guide plate 21. This facilitates the replacement of the collection box 22 without stopping the testing device, improving efficiency and convenience when using the testing device.

[0023] Reference Figure 1-5 As shown in this embodiment: the top two edges of the protruding rod 24 are arc-shaped. By setting the top two edges of the protruding rod 24 to be arc-shaped, when the sliding ring 26 is above the protruding rod 24, during the rotation of the round rod 23, when the through groove 27 on the outer surface of the sliding ring 26 and the position of the protruding rod 24 are close to coincide, the through groove 27 of the sliding ring 26 can more easily enter the outer surface of the protruding rod 24 and pass through the protruding rod 24. A gasket 211 is fixedly connected to one side of the stop rod 210. The gasket 211 is made of rubber. By setting the rubber gasket 211, the glass tube that enters the outer surface of the guide plate 21 and contacts the side of the stop rod 210 can be buffered, so as to avoid the glass tube being damaged by impact when it contacts the stop rod 210.

[0024] Reference Figure 2-5 As shown in this embodiment: an operating block 212 is fixedly connected to the top of the round rod 23. The outer surface of the operating block 212 is provided with several protrusions. Holding the protrusions on the outer surface of the operating block 212 makes it easier to rotate the operating block 212 to control the rotation of the round rod 23 and prevents the hand from slipping.

[0025] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6As shown in this embodiment: the convenient device 3 includes two insert rods 31, one end of each insert rod 31 is fixedly connected to one side of the collection box 22, and the end of each insert rod 31 away from the collection box 22 is rotatably connected to a rotating shaft 34. A second coil spring 35 is provided at the bottom end of the rotating shaft 34, and the two ends of the second coil spring 35 are fixedly connected to the outer surface of the second rotating shaft 34 and the outer surface of the insert rod 31, respectively. A locking block 36 is fixedly connected to the outer surface of the rotating shaft 34. Rectangular grooves 32 are provided on both sides of the guide plate 21, and a stop block 33 is fixedly connected to the inner wall of the rectangular groove 32. When installing the collection box 22, the two insert rods 31 at one end of the collection box 22 are inserted into the rectangular grooves 32 on both sides of the guide plate 21, respectively. Inside the rectangular groove 32, the collection box 22 is pushed to move towards the guide plate 21, causing the insertion rod 31 to move towards the stop block 33. When one end of the locking block 36 on the outer surface of the rotating shaft 34 contacts the surface of the stop block 33, it will be blocked by the stop block 33. The rotating shaft 34 rotates outward, causing one end of the locking block 36 to rotate to the outside of the locking block 36. When one end of the insertion rod 31 is in contact with one side of the stop block 33, the second coil spring 35 at the bottom of the rotating shaft 34 returns to its original state, which will drive the locking block 36 to rotate towards the stop block 33, so that one end of the locking block 36 is locked on one side of the stop block 33, restricting the position of the insertion rod 31 inside the rectangular groove 32, and installing the collection box 22 at one end of the guide plate 21.

[0026] Reference Figure 3 , Figure 4 and Figure 6 As shown in this embodiment: a groove block 37 is fixedly connected to one side of the locking block 36. A groove is provided on one side of the groove block 37. When removing the collection box 22, pinch the groove on the surface of the groove block 37 on one side of the locking block 36 and pull the groove block 37 to control the locking block 36 to rotate away from the guide plate 21. Then pull the collection box 22 to move the insertion rod 31 away from the rectangular groove 32 to quickly remove the collection box 22. Auxiliary plates 38 are fixedly connected to both sides of the collection box 22. Several arc-shaped grooves are provided on the outer surface of the auxiliary plates 38. Holding the arc-shaped grooves on the outer surface of the auxiliary plates 38 on both sides of the collection box 22 makes it easier to pick up the collection box 22 and control the collection box 22 to be disassembled and assembled.

[0027] Working principle: When using the detection device to detect defects on the surface of borosilicate medical glass tubes, firstly, rotate the round rods 23 on both sides of the top of the guide plate 21 to deform the first coil spring 25, aligning the position of the protrusion 24 on the outer surface of the round rod 23 with the position of the through groove 27 on the outer surface of the sliding ring 26. Then, pull the sliding ring 26 on the outer surface of the two round rods 23 upward to move the sliding ring 26 above the protrusion 24, raising the stop rod 210. Releasing the first coil spring 25 of the round rod 23 and restoring it to its original state will cause the round rod 23 to rotate in the original direction, causing the through groove 27 on the outer surface of the sliding ring 26 to be misaligned with the position of the protrusion 24 on the outer surface of the round rod 23, fixing the sliding ring 26 above the protrusion 24. Then, the two at one end of the collection box 22... Insert rods 31 are inserted into the rectangular slots 32 on both sides of the guide plate 21, pushing the collection box 22 to move towards the guide plate 21 and causing the insert rods 31 to move towards the stop block 33. When one end of the locking block 36 on the outer surface of the rotating shaft 34 contacts the surface of the stop block 33, it will be blocked by the stop block 33. The rotating shaft 34 rotates outward, causing one end of the locking block 36 to rotate to the outside of the locking block 36. When one end of the insert rod 31 is in contact with one side of the stop block 33, the second coil spring 35 at the bottom of the rotating shaft 34 returns to its original state and drives the locking block 36 to rotate towards the stop block 33, so that one end of the locking block 36 is locked on one side of the stop block 33, restricting the position of the insert rod 31 inside the rectangular slot 32 and installing the collection box 22 at one end of the guide plate 21.

[0028] The terminal operating device is then connected to the chassis 5 on one side of the rack 1. The control box on the outer surface of the rack 1 controls the operation of the conveyor device 4 and turns on the LED lights 7 and the industrial camera 6. The glass tube is then placed vertically on the conveyor belt of the conveyor frame away from the auxiliary device 2. A drive motor on one side of the conveyor frame drives the rotating rollers to move the conveyor belt, transporting the glass tube to the industrial camera 6. The LED lights 7 illuminate the glass tube, and the industrial camera 6 takes a picture. The captured image is compared with the image information stored in the server on the chassis 5. If there is a defect on the surface of the glass tube, the LED lights 7 are controlled to change color and the conveyor belt is stopped, allowing personnel to remove the defective product. After passing under the industrial camera 6, the glass tube moves towards the guide rod 8. The guide rod 8 blocks the glass tube, causing it to enter the guide plate 21 along its surface, and then through the guide plate 21 into the collection box 22. When the number of glass tubes is almost full, push the round rods 23 on both sides of the top of the guide plate 21 to rotate and deform the first coil spring 25. At this time, the stretched spring 28 returns to its original shape and pulls the two sliding rings 26 downward so that the bottom end of the stop rod 210 rests on the outer surface of the guide plate 21 to block the guide plate 21 and the collection box 22. At this time, pull the groove block 37 on the surface of the groove block 37 on one side of the two locking blocks 36 to control the locking block 36 to rotate away from the guide plate 21. Then pull the collection box 22 to move the insertion rod 31 away from the rectangular groove 32 to quickly remove the collection box 22. The glass tubes that have entered the guide plate 21 will stay inside the guide plate 21 for a short time. Use this time to remove the glass tubes inside the collection box 22 or replace the collection box 22. After the collection box 22 is replaced, move the sliding ring 26 to position the sliding ring 26 above the protruding rod 24 to raise the stop rod 210, so that the glass tubes on the outer surface of the guide plate 21 can enter the collection box 22 normally.
