Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, and more specifically to an online optical inspection instrument. Background Technology

[0002] Optical appearance inspection instruments are precision inspection devices based on optical principles. They are mainly used for identifying surface and internal defects, measuring geometric dimensions, and analyzing morphological features of objects. Automated optical inspection systems employ dual-sided synchronous imaging and high-speed industrial cameras, and are widely used in semiconductors, electronic manufacturing, optical components, and industrial metrology. Among these, the power cords of 3C products are mainly used for control installation, connecting equipment, and transmitting power. In daily use, they are often folded or tangled. Therefore, the uniformity of the internal components of the inner and outer sheaths significantly affects fatigue strength. The material formula of the power cord sheath is constantly improved according to market demand, resulting in many new materials for the sheath. For example, transparent sheaths are used for aesthetic purposes. When inspecting transparent sheaths, the uniformity of their internal components must be checked by an optical appearance inspection instrument.

[0003] Current optical inspection instruments do not have a high degree of compatibility with sheath conveying devices. Sheaths are often transported using conveyor belts or unwinding devices, which not only results in long inspection waiting times but also inaccurate results due to dust interference during the inspection process. Therefore, an online optical inspection instrument is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the current optical inspection instruments and sheath conveying devices are not well matched, resulting in long inspection waiting times and inaccurate results due to dust interference during the inspection process. This invention provides an online optical inspection instrument.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] An online optical inspection instrument includes an inspection platform. An optical inspection instrument body is fixedly mounted on the top of the inspection platform. Multiple evenly distributed sheath passage slots are formed on the top of the inspection platform, all located at the bottom of the optical inspection instrument body. Illumination strips are embedded in the inner walls of each sheath passage slot. Vertically arranged first fixed bearing frames are fixedly mounted at both ends of the inspection platform. A movable guide rail is provided on one side of each first fixed bearing frame. A vertically arranged movable bearing frame is slidably mounted on the top of each movable guide rail. A horizontally arranged unwinding flower-shaped shaft is rotatably mounted on both the first fixed bearing frame and the movable bearing frame on one side. Multiple evenly distributed unwinding reels are sleeved on the unwinding pattern shaft, and each unwinding reel is wound with a protective sleeve to be tested. On the other side, the first fixed bearing bracket and the movable bearing bracket are rotatably mounted on the same horizontally arranged take-up pattern shaft, and multiple evenly distributed take-up reels are sleeved on the take-up pattern shaft. A support frame is fixedly installed on the side of the testing platform facing the unwinding pattern shaft, and multiple evenly distributed guide tubes are fixedly installed on the support frame. The positions of the multiple guide tubes correspond to the positions of the multiple protective sleeve passage slots. The bottom end of the guide tube faces the testing platform and is fixedly installed with a constricted tube, and the top end of the guide tube faces the take-up reel and is fixedly installed with a flared tube.

[0007] Furthermore, a gantry frame is provided on both sides of the testing platform. A horizontally arranged reset linear module is fixedly installed at the bottom of the gantry frame. A suspension plate is fixedly installed at the bottom of the drive end of the reset linear module. A vertically arranged lifting arm is fixedly installed at the bottom of the suspension plate. An electric claw driver is fixedly installed at the telescopic end of the lifting arm. Multiple evenly distributed miniature electric grippers are fixedly installed at the bottom of the electric claw driver. The positions of the multiple miniature electric grippers correspond to the positions of the multiple guide cylinders. Traction rope passage holes adapted to the sheath traction rope are opened on the side walls of the winding reel and the winding flower shaft.

[0008] Furthermore, a traction and winding mechanism is provided on one side of the winding pattern shaft for traction and assisting in winding the sheath to be tested. The traction and winding mechanism includes two vertically arranged second fixed bearing brackets disposed on the side of the winding pattern shaft away from the testing table. The top ends of the two second fixed bearing brackets are rotatably mounted with the same traction shaft. A traction motor is fixedly mounted on one side of the top end of one of the traction shafts. The output end of the traction motor is drivenly connected to the traction shaft. Multiple sheath traction ropes are fixedly mounted on the traction shaft. The sheath traction ropes are arranged in pairs. One end of each pair of sheath traction ropes is fixedly mounted with the same sheath spring clip. The positions of the multiple sheath spring clips correspond to the positions of the multiple sheath passage slots. Spring clip passage holes adapted to the sheath spring clips are opened on both sides of the winding reel. Multiple clearance holes adapted to the spring clip passage holes are opened on the side wall of the winding pattern shaft.

[0009] Furthermore, two horizontally arranged guide linear modules are provided on one side of the testing platform. The top of the drive end of the guide linear module is fixedly installed with the same guide frame. The guide frame is located between the take-up flower shaft and the traction shaft. Multiple horizontally arranged guide cylinders are fixedly installed on the top of the guide frame. The positions of the multiple guide cylinders correspond to the positions of the multiple sheath passage slots. Each guide cylinder has a V-shaped guide hole inside.

[0010] Furthermore, a separation partition is fixedly installed inside each of the V-shaped guide holes, and the separation partition is located between the two sheath traction ropes.

[0011] Furthermore, the take-up reel is used to take up the sheath to be tested after it has been inspected by the optical inspection instrument body. The positions of the multiple take-up reels, the multiple take-up pattern shafts, and the multiple sheath passage slots are in one-to-one correspondence. A take-up motor is fixedly installed on one side of the top of one of the first fixed bearing brackets, and the output end of the take-up motor is drivenly connected to the take-up pattern shaft.

[0012] Furthermore, each of the sheath spring clips is fixedly fitted with anti-abrasion rubber, and each of the sheath passage grooves is fixedly installed with an isolation glass strip, with the lighting strip located at the bottom of the isolation glass strip.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention, by setting up an optical inspection instrument body, allows the optical inspection instrument body to inspect the portion of the sheath to be tested located at the bottom of the sheath when the sheath spring clip drags the sheath to be tested through each sheath passage slot. The illumination light at the bottom of the sheath passage slot provides reverse illumination, revealing the internal structure of the sheath to be tested. This facilitates the detection of structural defects and material uniformity issues by the optical inspection instrument body, enabling batch inspection of the sheaths to be tested and improving the inspection speed.

[0015] 2. This invention, by setting guide cylinders, allows the receiving linear module to drive multiple guide cylinders to move towards the take-up reel. After the sheath spring clip passes through the spring clip passage hole, it continues to enter the interior of the guide cylinder. Then, the traction shaft rewinds, pulling the sheath spring clip into the interior of the V-shaped guide hole. Consequently, the two ends of the sheath spring clip are squeezed by the inner walls of the two sides of the V-shaped guide hole, thus automatically opening and releasing the sheath to be tested. At the same time, the sheath to be tested is positioned, making it convenient for the miniature electric gripper to grasp the sheath to be tested for the next round of testing.

[0016] 3. By setting up anti-abrasion rubber, the anti-abrasion rubber will rub against the inner wall of the sheath passage and the isolation glass strip at the bottom as it slides in the sheath passage, thereby generating static electricity. This static electricity will attract dust inside the sheath passage, achieving automatic dust removal and reducing the impact of dust particles on the detection. Subsequently, a dust collection device can be connected to remove dust from the sheath spring clip separately. In addition to protecting the lighting strip, the isolation glass strip can also accelerate the generation of static electricity on the anti-abrasion rubber. Attached Figure Description

[0032] like Figures 1 to 10 As shown, an online optical inspection instrument includes an inspection stage 1, such as... Figure 1 , Figure 2 As shown, specifically, an optical inspection instrument body 2 is fixedly installed on the top of the inspection platform 1. Multiple evenly distributed sheath passage slots 101 are formed on the top of the inspection platform 1. All sheath passage slots 101 are located at the bottom of the optical inspection instrument body 2. Illumination strips are embedded and fixed on the inner walls of each sheath passage slot 101, such as... Figure 4 , Figure 5 As shown, both ends of the testing table 1 are fixedly equipped with vertically arranged first fixed bearing frames 3. A movable guide rail 4 is provided on one side of each first fixed bearing frame 3. A vertically arranged movable bearing frame 5 is slidably installed on the top of each movable guide rail 4. On one side of the first fixed bearing frame 3 and the movable bearing frame 5, a horizontally arranged unwinding patterned shaft 6 is rotatably mounted. Multiple evenly distributed unwinding reels 7 are sleeved on the unwinding patterned shaft 6, and each unwinding reel 7 is wound with a protective sleeve 8 to be tested. On the other side of the first fixed bearing frame 3 and the movable bearing frame 5, a horizontally arranged take-up patterned shaft 9 is rotatably mounted. Multiple evenly distributed take-up reels 10 are sleeved on the take-up patterned shaft 9. Figure 2 , Figure 7 As shown, a support frame 27 is fixedly installed on the side of the inspection table 1 facing the unwinding flower-shaped shaft 6. Multiple evenly distributed guide tubes 28 are fixedly installed on the support frame 27. The positions of the multiple guide tubes 28 correspond to the positions of multiple sheath passage slots 101. The bottom end of the guide tube 28 faces the inspection table 1 and is fixedly installed with a constriction tube 29. The top end of the guide tube 28 faces the take-up reel 10 and is fixedly installed with a flared tube 30.

[0033] More specifically, when the online optical inspection instrument performs inspection, it first pulls on one side of the movable bearing bracket 5 to disengage it from the unwinding pattern shaft 6. Multiple unwinding reels 7 are then sequentially fitted onto the unwinding pattern shaft 6 in the same orientation. The movable bearing bracket 5 is then pushed back to its original position, locking the unwinding reels 7 onto the unwinding pattern shaft 6. Similarly, each take-up reel 10 is fitted onto the take-up pattern shaft 9, ensuring that the traction rope passage hole 1002 on the take-up reel 10 is aligned with the traction rope passage hole on the take-up pattern shaft 9. 1002 Keep the connection in the same direction, then pinch one end of each sheath 8 to be tested in sequence and send it into each flared tube 30. Rotate the unwinding reel 7 so that each sheath 8 to be tested passes through the flared tube 30 and the guide tube 28 in sequence and protrudes from one end of the constricted tube 29. The flared tube 30, the guide tube 28, and the constricted tube 29 play a guiding and limiting role for the sheath 8 to be tested, thereby achieving the positioning of the sheath 8 to be tested. This makes it convenient for each sheath spring clip 16 to clamp and pull one end of multiple sheaths 8 to be tested.

[0034] like Figure 1 , Figure 10 As shown, specifically, a gantry frame 21 is provided on both sides of the testing table 1. A horizontally arranged reset linear module 22 is fixedly installed at the bottom of the gantry frame 21. A suspension plate 23 is fixedly installed at the bottom of the drive end of the reset linear module 22. A vertically arranged lifting arm 24 is fixedly installed at the bottom of the suspension plate 23. An electric claw driver 25 is fixedly installed at the telescopic end of the lifting arm 24. Multiple evenly distributed miniature electric grippers 26 are fixedly installed at the bottom of the electric claw driver 25. The positions of the multiple miniature electric grippers 26 correspond to the positions of the multiple guide cylinders 19. Traction rope passage holes 1002 adapted to the sheath traction rope 32 are opened on the side walls of the winding reel 10 and the winding flower-shaped shaft 9.

[0035] In this embodiment, the miniature electric gripper 26 can be a bidirectional actuator driven by electricity, which drives the two drive ends to move in opposite directions through a screw mechanism, linear motor module, etc. The power source of the miniature electric gripper 26 can also be replaced by a cylinder. The guiding linear module 17 and the resetting linear module 22 can both be common linear actuators in the prior art, such as a linear motor module, which drives the mover as the drive end to move linearly through the electromagnetic force of the motor stator, or uses a screw thread sleeve, belt and pulley, chain and sprocket mechanism, etc., to make the drive end move linearly through the thread guiding action or meshing action. In addition to electric power, cylinders, hydraulic rods and other components can also be used as power sources. The guiding linear module 17 and the resetting linear module 22 in this embodiment can adopt technical solutions including but not limited to the above, depending on the actual situation. The lifting arm 24 can be a common large electric push rod mechanism in the prior art.

[0036] More specifically, by setting up miniature electric grippers 26, the lifting arm 24 drives the electric gripper driver 25 and the miniature electric grippers 26 to move down synchronously to one side of the guide cylinder 19. At this time, a portion of each sheath spring clamp 16 is located inside the respective guide cylinder 19. The two gripping ends of the miniature electric grippers 26 move down to both sides of the sheath spring clamp 16. The electric gripper driver 25 drives the gripping ends of the miniature electric grippers 26 to clamp the sheath spring clamp 16, keeping the sheath spring clamp 16 in an open state. Then, the reset linear module 22 first drives the multiple miniature electric grippers 26 to move horizontally a short distance through the suspension plate 23, causing the sheath spring clamp 16 to disengage. After the guide tube 19 is lifted and reset, the lifting arm 24 is raised and reset. The reset linear module 22 drives the sheath spring clip 16 to move together to the guide tube 28. The lifting arm 24 then controls each sheath spring clip 16 to descend to the port of the constriction tube 29. The miniature electric gripper 26 releases the sheath spring clip 16. Under the action of elasticity, the sheath spring clip 16 clamps one end of each sheath 8 to be tested. At the same time, each sheath traction rope 32 will pass through the traction rope passage hole 1002 on the take-up reel 10 and the take-up flower-shaped shaft 9 in sequence to enter the spring clip passage hole 1001 and the clearance hole, completing the automatic connection between the sheath spring clip 16 and the sheath 8 to be tested, which facilitates the subsequent traction work of the sheath 8 to be tested.

[0037] A traction and winding mechanism is provided on one side of the winding pattern shaft 9 for pulling and assisting in the winding of the sheath 8 to be tested, such as... Figure 2 , Figure 3 As shown, specifically, the traction winding mechanism includes two vertically arranged second fixed bearing brackets 12 disposed on the side of the winding pattern shaft 9 away from the detection table 1. The top of the two second fixed bearing brackets 12 is rotatably mounted with the same traction shaft 13. A traction motor 14 is fixedly mounted on one side of the top of one of the traction shafts 13. The output end of the traction motor 14 is drivenly connected to the traction shaft 13. Multiple evenly distributed sheath traction ropes 32 are fixedly mounted on the traction shaft 13. The sheath traction ropes 32 are in pairs. One end of each pair of sheath traction ropes 32 is fixedly mounted with the same sheath spring clip 16. The positions of the multiple sheath spring clips 16 correspond to the positions of multiple sheath passage slots 101. Spring clip passage holes 1001 adapted to the sheath spring clips 16 are opened on both sides of the winding reel 10. Multiple clearance holes adapted to the spring clip passage holes 1001 are opened on the side wall of the winding pattern shaft 9.

[0038] More specifically, by setting up a traction winding mechanism, the traction motor 14 drives the traction shaft 13 to rotate, which in turn drives the sheath spring clips 16 to slide in the sheath passage groove 101 through the sheath traction ropes 32, until the sheath spring clips 16 drive the sheath to be tested 8 to pass through the first spring clip passage hole 1001, the clearance hole and the second spring clip passage hole 1001 in sequence, so that the sheath to be tested 8 passes through the winding reel 10 and the winding pattern shaft 9. Then the winding motor 11 drives the winding pattern shaft 9 to drive the multiple winding reels 10 to start rotating and to wind up the sheath to be tested 8. Since one end of the sheath to be tested 8 is still clamped to the other side of the winding reel 10 by the sheath spring clips 16, the sheath to be tested 8 will not fall off the winding reel 10 during the winding process.

[0039] like Figure 2 , Figure 8 As shown, specifically, two horizontally arranged guide linear modules 17 are provided on one side of the testing table 1. A single guide support 18 is fixedly installed on the top of the drive end of each guide linear module 17. The guide support 18 is located between the take-up spiral shaft 9 and the traction shaft 13. Multiple horizontally arranged guide cylinders 19 are fixedly installed on the top of the guide support 18. The positions of the multiple guide cylinders 19 correspond to the positions of multiple sheath passage slots 101, such as... Figure 9 As shown, V-shaped guide holes 1901 are provided inside the guide cylinder 19.

[0040] More specifically, by setting guide cylinders 19, before the sheath traction rope 32 drives the sheath spring clip 16 through the take-up reel 10, the receiving linear module 17 will drive multiple guide cylinders 19 to move toward the take-up reel 10 via the receiving stand 18, so that each guide cylinder 19 is on one side of its respective take-up reel 10. This allows the sheath spring clip 16 to pass through the spring clip passage hole 1001 and continue into the interior of the guide cylinder 19. Then, the traction shaft 13 simultaneously winds up the sheath traction rope 32 and the receiving linear module 17 returns to its original position. Once the guide linear module 17 is fully reset, the traction motor 14 stops winding. When the sheath 8 to be tested begins to wind on the winding reel 10, the traction motor 14 drives the traction shaft 13 to wind again, causing the sheath spring clip 16 to be pulled into the V-shaped guide hole 1901. As a result, the two ends of the sheath spring clip 16 are squeezed by the inner walls of the V-shaped guide hole 1901, and then automatically open, releasing the sheath 8 to be tested. At the same time, the sheath 8 to be tested is positioned, making it convenient for the miniature electric gripper 26 to grasp the sheath 8 to be tested for the next round of testing.

[0041] like Figure 9 As shown, specifically, a separation partition 20 is fixedly installed inside each of the V-shaped guide holes 1901, and the separation partition 20 is located between the two sheath traction ropes 32.

[0042] In this embodiment, the flared end of the V-shaped guide hole 1901 faces the winding flower-shaped shaft 9, and its constricted end faces the traction shaft 13.

[0043] More specifically, by setting the separation partition 20 so that the separation partition 20 is inside the V-shaped guide hole 1901, the part of the sheath traction rope 32 inside the V-shaped guide hole 1901 can always be kept separate, thereby preventing the two sheath traction ropes 32 from getting tangled and causing the sheath spring clip 16 to be misaligned with the V-shaped guide hole 1901.

[0044] like Figure 1 , Figure 5 As shown, specifically, the take-up reel 10 is used to take up the sheath 8 to be tested after being inspected by the optical inspection instrument body 2. The positions of multiple take-up reels 10, multiple take-up patterned shafts 9, and multiple sheath passage slots 101 are in one-to-one correspondence. A take-up motor 11 is fixedly installed on one side of the top of one of the first fixed bearing brackets 3. The output end of the take-up motor 11 is driven and connected to the take-up patterned shaft 9.

[0045] More specifically, by setting up the optical inspection instrument body 2, when the sheath spring clip 16 drags the sheath 8 to be tested through each sheath passage slot 101, the portion of the sheath 8 to be tested at the bottom of the optical inspection instrument body 2 is inspected. The lighting at the bottom of the sheath passage slot 101 is reversed to illuminate the internal structure of the sheath 8 to be tested, making it easier for the optical inspection instrument body 2 to detect structural defects and material uniformity issues, thus enabling batch inspection of the sheath 8 to be tested and improving the inspection speed.

[0046] like Figure 3 As shown, specifically, anti-abrasion rubber 31 is fixedly sleeved on the sheath spring clip 16, and isolation glass strips 15 are fixedly installed inside the sheath passage groove 101, with the lighting strips located at the bottom of the isolation glass strips 15.

[0047] More specifically, by setting up the anti-abrasion rubber 31, the anti-abrasion rubber 31 will rub against the inner wall of the sheath passage groove 101 and the bottom isolation glass strip 15 during the sliding process in the sheath passage groove 101, thereby generating static electricity, which will adsorb the dust inside the sheath passage groove 101, realize automatic dust removal, reduce the impact of dust particles on detection, and then connect a dust collection device to remove dust from the sheath spring clip 16 separately. In addition to protecting the lighting strip, the isolation glass strip 15 can also accelerate the generation of static electricity on the anti-abrasion rubber 31.

[0048] In summary: When performing testing, the online optical inspection instrument first pulls on one side of the movable bearing bracket 5 to disengage it from the unwinding pattern shaft 6. Multiple unwinding reels 7 are then sequentially fitted onto the unwinding pattern shaft 6 in the same orientation. The movable bearing bracket 5 is then pushed back to its original position, locking the unwinding reels 7 onto the unwinding pattern shaft 6. Similarly, each take-up reel 10 is fitted onto the take-up pattern shaft 9, ensuring that the traction rope passage hole 1002 on the take-up reel 10 is connected to the traction rope passage hole 1002 on the take-up pattern shaft 9 in the same direction. Then, one end of each sheath 8 to be tested is pinched and inserted into each flared tube 30. The unwinding reel 7 is rotated, causing each sheath 8 to pass through the flared tube 30 and guide tube 28 sequentially, protruding from one end of the constricted tube 29. This allows the flared tube 30 and guide tube... 28. The constricted tube 29 serves as a guide and limiter for the sheath 8 to be tested, enabling the positioning of the sheath 8 and facilitating the subsequent clamping and pulling of one end of each sheath 8 by the sheath spring clamps 16. By setting up the miniature electric gripper 26, the lifting arm 24 drives the electric gripper driver 25 and the miniature electric gripper 26 to move down synchronously to one side of the guide cylinder 19. At this time, a portion of each sheath spring clamp 16 is inside the guide cylinder 19. The two clamping ends of the miniature electric gripper 26 move down to both sides of the sheath spring clamp 16. The electric gripper driver 25 drives the clamping ends to clamp the sheath spring clamp 16 through the miniature electric gripper 26, keeping the sheath spring clamp 16 in an open state. Then, the reset linear module 22 is first driven by the suspension plate 23. Multiple miniature electric grippers 26 move horizontally a short distance, causing the sheath spring clips 16 to disengage from the guide tube 19. Then, the lifting arm 24 rises and resets, and the reset linear module 22 moves the sheath spring clips 16 together towards the guide tube 28. The lifting arm 24 then controls each sheath spring clip 16 to descend to the end of the constricted tube 29. The miniature electric grippers 26 release the sheath spring clips 16, which, under elastic action, clamp one end of each sheath 8 to be tested. Simultaneously, each sheath traction rope 32 passes sequentially through the traction rope passage holes 1002 on the take-up reel 10 and the take-up spiral shaft 9, entering the spring clip passage hole 1001 and the clearance hole, completing the automatic connection between the sheath spring clips 16 and the sheath 8 to be tested. This facilitates subsequent traction work of the sheath 8 to be tested. (The last sentence appears to be incomplete and requires further context.) The traction and winding mechanism causes the traction motor 14 to drive the traction shaft 13 to rotate, which in turn drives the sheath spring clips 16 to slide in the sheath passage grooves 101 through the sheath traction ropes 32. The sheath spring clips 16 then drive the sheath 8 to be tested to pass sequentially through the first spring clip passage hole 1001, the clearance hole, and the second spring clip passage hole 1001, allowing the sheath 8 to pass through the winding reel 10 and the winding pattern shaft 9. Then, the winding motor 11 drives the winding pattern shaft 9 to rotate the multiple winding reels 10 to wind up the sheath 8. Since one end of the sheath 8 is still clamped to the other side of the winding reel 10 by the sheath spring clips 16, the sheath 8 will not fall off the winding reel 10 during the winding process.By setting guide cylinders 19, before the sheath traction rope 32 drives the sheath spring clip 16 through the take-up reel 10, the receiving linear module 17 will drive multiple guide cylinders 19 to move toward the take-up reel 10 via the receiving stand 18, so that each guide cylinder 19 is on one side of its respective take-up reel 10. This allows the sheath spring clip 16 to pass through the spring clip passage hole 1001 and continue into the interior of the guide cylinder 19. Then, the traction shaft 13 simultaneously winds up the sheath traction rope 32 and resets the receiving linear module 17 until the receiving linear module 17 is fully reset. The traction motor 14 then stops winding. When the test sleeve 8 begins to wind up on the take-up reel 10, the traction motor 14 drives the traction shaft 13 to wind up again, pulling the sleeve spring clip 16 into the V-shaped guide hole 1901. This causes the two ends of the sleeve spring clip 16 to be pressed against the inner walls of the V-shaped guide hole 1901, automatically opening and releasing the test sleeve 8. Simultaneously, the test sleeve 8 is positioned, facilitating the gripper 26 to grasp it for the next round of testing. By setting a separation partition 20, which is positioned inside the V-shaped guide hole 1901, the sleeve traction rope 32 can be positioned within the V-shaped guide hole. The portion inside the V-shaped guide hole 1901 remains separated to prevent the two sheath traction ropes 32 from tangling and causing misalignment between the sheath spring clip 16 and the V-shaped guide hole 1901. By setting up the optical inspection instrument body 2, when the sheath spring clip 16 drags the sheath 8 under test through each sheath passage slot 101, the portion of the sheath 8 under test located at the bottom of the optical inspection instrument body 2 is inspected. The lighting at the bottom of the sheath passage slot 101 is reversed to illuminate the internal structure of the sheath 8 under test, facilitating the detection of structural defects and material uniformity issues by the optical inspection instrument body 2. The batch testing of the sheath 8 improves the testing speed. By setting up the anti-abrasion rubber 31, as the anti-abrasion rubber 31 slides in the sheath passage groove 101, it rubs against the inner wall of the passage groove 101 and the bottom isolation glass strip 15, thereby generating static electricity. This static electricity attracts dust inside the passage groove 101, achieving automatic dust removal and reducing the impact of dust particles on the testing. Subsequently, a dust collection device can be connected to remove dust from the sheath spring clip 16 separately. In addition to protecting the lighting strip, the isolation glass strip 15 also accelerates the generation of static electricity on the anti-abrasion rubber 31.
