Description

Technical Field

[0001] The present invention relates to a double-station coil stock vision inspection machine, belonging to the technical field of film inspection. Background Art

[0002] Most of the existing coil stock quality inspections are based on manual visual inspection, with low efficiency and poor inspection efficiency. In fact, visual inspection by human eyes is also prone to fatigue and missed inspections, resulting in unstable product quality and relatively high labor costs. Visual inspection is to use a machine to replace the human eye for measurement and judgment. Visual inspection refers to converting the captured target into an image signal through a machine vision product (i.e., an image acquisition device, which is divided into two types: CMOS and CCD), and transmitting it to a dedicated image processing system. The image system performs various operations on these signals to extract the features of the target, and then controls the on-site equipment actions according to the discrimination results.

[0003] After retrieval, the patent with the publication number CN108982530A discloses "a detection system for backlight coil stock", which includes a conveying unit, an image acquisition unit, and a detection unit; the conveying unit is used to convey the backlight coil stock to be detected; the backlight coil stock to be detected passes through the image acquisition unit through the conveying unit; the image acquisition unit is used to acquire the image of the backlight coil stock to be detected; the detection unit obtains the image of the backlight coil stock to be detected and analyzes whether there are defects in the backlight coil stock to be detected according to the image of the backlight coil stock to be detected. This device can improve the detection rate and inspection efficiency of defective backlight coil stock.

[0004] During use, the material tape is driven to move by the unwinding shaft and the winding shaft, and the detection device is used to replace personnel to detect the product. After some devices detect unqualified products, the control device stops the machine to repair the unqualified products and then continues to transport. However, there is still a risk that the products repaired by personnel are still unqualified. Generally, the risk of defective products flowing out is reduced by detecting again after winding. During the transmission of the material tape, since the rotation angles of the unwinding shaft and the winding shaft are generally fixed, and the diameter of the material reel on the unwinding shaft gradually decreases during unwinding, and the diameter of the material reel on the winding shaft gradually increases during winding, it results in that in a single rotation of the unwinding shaft and the winding shaft, the length of the material unwound by the unwinding shaft is inconsistent with the length of the material wound by the winding shaft, and it will also cause the moving distance of the material during forward transmission on the carrier table to be different from the moving distance during reverse retraction, resulting in the situation that the detected product is misaligned with the detection area, and personnel need to adjust its position multiple times, which affects the overall detection efficiency. Summary of the Invention

[0005] The object of the present invention is to provide a double-station coiled material vision inspection machine, which not only improves the qualified rate of products, greatly reduces the probability of missed inspection of defective products, but also ensures the consistent distance of the coiled material baseband, improves the position accuracy of the coiled material baseband transmission, and thus improves the overall inspection and repair efficiency.

[0006] To achieve the above object, the technical solution adopted by the present invention is: a double-station coiled material vision inspection machine, which is used to transfer the film coiled material tape, and the transferred film coiled material tape includes: a coiled material baseband with products, and a protective film tape adhered to the coiled material baseband. The double-station coiled material vision inspection machine includes: a loading platform, a computer mainframe, and a first display screen connected to the computer mainframe. Two groups of detection devices are arranged at intervals along the length direction on the loading platform, and a repair platform is arranged between the two groups of detection devices. The first display screen is located on one side of the repair platform; One end of the loading platform is provided with a first unwinding shaft, and the other end is provided with a first rewinding shaft. A strip-shaped hole is respectively opened on the loading platform between the first unwinding shaft and one detection device, and between the other detection device and the first rewinding shaft. A driving roller is arranged below the strip-shaped hole, and the driving roller is fixedly connected to the output shaft of a servo motor. A support frame is arranged above the strip-shaped hole, and a driven roller capable of frictionally contacting the driving roller is arranged between the support frame and the strip-shaped hole. A driving mechanism is arranged between the support frame and the driven roller to drive the driven roller to contact or separate from the driving roller.

[0007] The further improved solutions in the above technical solutions are as follows: 1. In the above solution, the first unwinding shaft and the first rewinding shaft are respectively rotatably installed on a box body with a motor inside. A transmission rod is arranged inside the box body and on one side of the motor. The first unwinding shaft and the first rewinding shaft are fixedly connected to one end of the transmission rod. A top block is sleeved on the outer wall of the other end of the transmission rod. The output shaft of the motor is fixedly installed with a resisting block, and the resisting block is in frictional contact with the top block.

[0008] 2. In the above solution, a first nut is threadedly connected to the outer wall of the transmission rod on the side of the top block opposite to the resisting block, and a first elastic member is arranged between the first nut and the top block.

[0009] 3. In the above solution, a transmission piece is arranged between the resisting block and the top block.

[0010] 4. In the above solution, a number of balls are rotatably installed on the transmission piece, and a chute matched with the balls is opened on the opposite sides of the top block and the resisting block.

[0011] 5. In the above solution, a second nut is threadedly connected to the outer wall of the transmission rod on the side of the first nut opposite to the top block.

[0012] 6. In the above solution, the driving mechanism includes: a mounting frame, a cylinder fixedly mounted on the support frame, the driven roller is rotatably mounted inside the mounting frame, and the movable end of the cylinder is fixedly connected to the mounting frame.

[0013] 7. In the above solution, the detection device includes: a light-transmitting plate mounted on the loading platform, a front telecentric camera located above the light-transmitting plate, and the front telecentric camera is connected to the computer host.

[0014] 8. In the above solution, a rear telecentric camera connected to the computer host is provided below the light-transmitting plate on one side of the front telecentric camera.

[0015] 9. In the above solution, the repair platform includes: a second display screen horizontally mounted on the loading platform, and the second display screen with its upper surface flush with the loading platform is connected to the computer host.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: 1. The double-station coil material vision inspection machine of the present invention sets two sets of detection devices to detect the product multiple times, and a repair platform is arranged between the two sets of detection devices. When the first detection device detects that the product is unqualified, the operator repairs the product on the repair platform, which improves the qualified rate of the product, greatly reduces the probability of missed detection of defective products, and clamps the coil material base belt through the driving roller and the driven roller, and drives the coil material base belt to move forward under the drive of the servo motor. When both detection devices detect that the product is unqualified, the servo motor is controlled to drive the coil material base belt to move backward and return to the first detection device for re-detection. If it is still unqualified, continue to repair. After repair, move forward and pass through the second detection device. If it is judged to be qualified, continue to transmit. During this process, the servo motor controls the driving roller to rotate to drive the coil material base belt to move forward or backward, avoiding the situation of product misalignment caused by different moving distances of the coil material base belt due to changes in the coil diameter, ensuring that the moving distance of the coil material base belt is consistent each time, thereby improving the transmission accuracy of the coil material base belt, being beneficial to improving the position accuracy of the product, facilitating the operator to detect and repair, and thus improving the overall detection and repair efficiency.

[0017] 2. The double-station coil stock visual inspection machine of the present invention clamps the coil stock baseband through the driving roller and the driven roller, and drives the driving roller to rotate through the servo motor to realize the movement of the coil stock baseband. The first unwinding shaft and the second unwinding shaft are rotationally connected by being fixedly connected to the transmission rod inside the box body. A resisting block and a pushing block are arranged between the transmission rod and the output shaft of the motor. When the output shaft of the motor rotates, it drives the transmission rod to rotate through friction, thereby driving the first unwinding shaft and the second unwinding shaft to rotate. When the direction of the coil stock baseband changes, since the driving roller and the driven roller clamp the coil stock baseband, if the driving roller and the driven roller are not controlled in time, one end of the coil stock baseband will be clamped and the other end will be pulled, resulting in a tight state. If the motor continuously drives the first unwinding shaft and the second unwinding shaft to rotate, the sliding will occur between the resisting block and the pushing block on the output shaft of the motor, thereby weakening the transmission force between the motor and the transmission rod, avoiding the situation that the excessive pulling force on the coil stock baseband caused by continuous driving leads to the breakage of the coil stock baseband, and thus ensuring the safety of the coil stock baseband.

Embodiment

[0020] The present patent can be further clearly understood through the specific embodiments given below, but they do not limit the present patent.

[0021] Embodiment 1: A double-station roll material vision inspection machine, which is used to transfer the film roll material belt 100, and the transferred film roll material belt 100 includes: a roll material base belt with products, and a protective film belt adhered to the roll material base belt. The double-station roll material vision inspection machine includes: a loading platform 1, a computer mainframe 7, and a first display screen 8 connected to the computer mainframe 7. On the loading platform 1, two groups of detection devices 200 are arranged at intervals along its length direction. A repair platform 101 is arranged between the two groups of detection devices 200, and the first display screen 8 is located on one side of the repair platform 101; The transferred film roll material belt is sleeved on the first unwinding shaft, and one end of the transferred film roll material is pulled out so that the roll material base belt and the protective film belt are separated. The protective film belt is wound on the second winding shaft, and the roll material base belt passes between the driving roller and the driven roller and is transmitted on the loading platform. During the transmission process, the two groups of detection devices can detect the roll material base belt, and unqualified products can be repaired on the repair platform. The products that pass the detection continue to be transmitted, and then the qualified roll material base belt is attached to the protective film belt on the second unwinding shaft and wound together on the first winding shaft; One end of the loading platform 1 is provided with a first unwinding shaft 2, and the other end is provided with a first winding shaft 4. A strip-shaped hole 24 is respectively opened on the loading platform 1 between the first unwinding shaft 2 and one detection device 200, between the other detection device 200 and the first winding shaft 4. A driving roller 25 is arranged below the strip-shaped hole 24, and the driving roller 25 is fixedly connected to the output shaft of a servo motor 27. A support frame 28 is arranged above the strip-shaped hole 24, and a driven roller 26 that can be in frictional contact with the driving roller 25 is arranged between the support frame 28 and the strip-shaped hole 24. A driving mechanism is arranged between the support frame 28 and the driven roller 26 to drive the driven roller 26 to contact or separate from the driving roller 25; During the movement of the roll material base belt, first, the downstream driving roller and the driven roller clamp the roll material base belt, and the driving roller is driven to rotate by the servo motor, thereby driving the roll material base belt to move forward. During the movement of the roll material base belt, the first detection device performs the first detection, and then the roll material base belt reaches the second detection device after passing through the repair platform, and the second detection device can perform a re-inspection and comparison.

[0022] The first material feeding shaft 2 and the first material winding shaft 4 are each rotatably mounted on a box body 14 with a motor 11 arranged inside. A transmission rod 15 is arranged inside the box body 14 and on one side of the motor 11. The first material feeding shaft 2 and the first material winding shaft 4 are fixedly connected to one end of the transmission rod 15. An abutting block 12 is sleeved on the outer wall of the other end of the transmission rod 15. The output shaft of the motor 11 is fixedly installed with an abutting block 16, and the abutting block 16 is in frictional contact with the abutting block 12 so that the output shaft of the motor 11 drives the transmission rod 15 to rotate; A first nut 17 is threadedly connected to the outer wall of the transmission rod 15 on the side of the abutting block 12 opposite to the abutting block 16. A first elastic member 18 is arranged between the first nut 17 and the abutting block 12; The first material feeding shaft, the first material winding shaft, the second material feeding shaft, and the second material winding shaft rotate through the box body. The motor inside the box body is connected to the transmission rod through the abutting block, the transmission piece, and the abutting block. Rotate the first nut on the transmission rod to adjust the compression amount of the elastic member, and then adjust the frictional force between the abutting block, the abutting block, and the transmission piece. Rotating the second nut can prevent the first nut from rotating relatively due to the rotational movement of the transmission rod, realizing the locking of the first nut; When the coiled material baseband needs to be wound in the reverse direction, when the coiled material baseband is in a taut state, the balls are mutually abutted tightly through the abutting block and the abutting block, and the driving force of the motor is transmitted between the abutting block and the abutting block, thereby driving the transmission rod to rotate in the reverse direction. If the pulling force of the coiled material baseband is too large, the sliding grooves formed on the surfaces of the abutting block and the abutting block slide with the balls inside the transmission piece, resulting in slipping between the abutting block, the transmission piece, and the abutting block, thereby losing the driving force for the transmission rod and avoiding the situation that the pulling force of the coiled material baseband increases continuously due to the continuous rotation of the transmission rod, causing the coiled material baseband to break; A transmission piece 20 is arranged between the abutting block 16 and the abutting block 12.

[0023] A number of balls 21 are rotatably mounted on the transmission piece 20, and a sliding groove 22 matching the balls 21 is formed on the opposite sides of the abutting block 12 and the abutting block 16.

[0024] A second nut 19 is threadedly connected to the outer wall of the transmission rod 15 on the side of the first nut 17 opposite to the abutting block 12.

[0025] The driving mechanism includes: a mounting frame 30, a cylinder 29 fixedly installed on the support frame 28. The driven roller 26 is rotatably mounted inside the mounting frame 30, and the movable end of the cylinder 29 is fixedly connected to the mounting frame 30.

[0026] The above detection device 201 includes: a light-transmitting plate 201 installed on the loading platform 1, a front telecentric camera 601 located above the light-transmitting plate 201, and the front telecentric camera 601 is connected to the computer mainframe 7.

[0027] A reverse telecentric camera 602 connected to the computer mainframe 7 is provided below the light-transmitting plate 201 and on one side of the front telecentric camera 601.

[0028] If the quality of the rolled material is qualified, the rolled material baseband continues to move for winding. If the quality of the rolled material baseband is unqualified, the downstream air cylinder drives the mounting rack to move upward, separating the driving roller and the driven roller. The first unwinding shaft, the first winding shaft, the second unwinding shaft, and the second winding shaft reverse. The upstream air cylinder drives the mounting rack to move downward, causing the driving roller and the driven roller to contact, thereby driving the rolled material baseband with defects to return to the first detection device for re-inspection, and then moving to the repair platform. The data of the detection device is presented on the first display through the computer mainframe, and the unqualified products are highlighted on the second display. The above repair platform 101 includes: a second display screen 9 horizontally installed on the loading platform 1, and the second display screen 9 with the upper surface flush with the loading platform 1 is connected to the computer mainframe 7.

[0029] It is convenient for personnel to quickly find the corresponding products. The staff can then repair the unqualified products. After the repair is completed, the driving roller and the driven roller upstream are separated, and the driving roller and the driven roller downstream are in contact, thereby driving the rolled material baseband to pass through the second detection device for detection again. If the detection is qualified, the rolled material baseband is wound.

[0030] A second winding shaft 5 for winding the protective film tape is provided above the first unwinding shaft 2, and a second unwinding shaft 3 for unwinding the protective film tape is provided above the first winding shaft 4.

[0031] A slide rail 31 is provided on the inner side wall of the above support frame 28, and the above mounting rack 30 is slidably connected to the slide rail 31 through a slider 32.

[0032] The shape of the above second rotating frame 391 is L-shaped.

[0033] The above sliders 32 are provided on the two side walls of the above mounting rack 30, and the two sliders 32 are symmetrically arranged about the axis of the mounting rack 30.

[0034] The computer mainframe 7 is electrically connected to the servo motor 27, the motor 11, the first display screen 8, the second display screen 9, the surface light source 202, the backlight source 203, the front telecentric camera 601, and the reverse telecentric camera 602.

[0035] Embodiment 2: A double-station roll material vision inspection machine, which is used to transfer the film roll material belt 100, and the transferred film roll material belt 100 includes: a roll base belt with products, and a protective film belt adhered to the roll base belt. The double-station roll material vision inspection machine includes: a loading platform 1, a computer mainframe 7, and a first display screen 8 connected to the computer mainframe 7. On the loading platform 1, two groups of detection devices 200 are arranged at intervals along its length direction. A repair platform 101 is arranged between the two groups of detection devices 200, and the first display screen 8 is located on one side of the repair platform 101; By arranging two light-transmitting plates on the loading platform, and a front telecentric camera is arranged above each light-transmitting plate and a back telecentric camera is arranged below it. When the first motor drives the first unwinding shaft to rotate forward and the second motor drives the first winding shaft to rotate forward, the roll base belt can be driven to transmit forward. During this process, after being detected by the two front telecentric cameras and the two back telecentric cameras, the probability of missed detection is greatly reduced; If the first front telecentric camera detects unqualified products, by controlling the first motor and the second motor to drive the roll base belt to move to the repair platform, after the personnel repair it, it is then continued to be transmitted to the second front telecentric camera and the back telecentric camera for detection. If it is qualified, it is continued to be transmitted, thereby improving the reliability of detection and ensuring product quality; One end of the loading platform 1 is provided with a first unwinding shaft 2, and the other end is provided with a first winding shaft 4. A strip-shaped hole 24 is respectively opened on the loading platform 1 between the first unwinding shaft 2 and one detection device 200, and between the other detection device 200 and the first winding shaft 4. A driving roller 25 is arranged below the strip-shaped hole 24, and the driving roller 25 is fixedly connected to the output shaft of a servo motor 27; By arranging two groups of detection devices to perform multiple detections on the products, and a repair platform is arranged between the two groups of detection devices. When the first detection device detects unqualified products, the personnel repair the products on the repair platform, and the roll base belt is clamped by the driving roller and the driven roller, and is driven to move forward under the drive of the servo motor; A support frame 28 is arranged above the strip-shaped hole 24, and a driven roller 26 that can be in frictional contact with the driving roller 25 is arranged between the support frame 28 and the strip-shaped hole 24. A driving mechanism is arranged between the support frame 28 and the driven roller 26 to drive the driven roller 26 to contact or separate from the driving roller 25; When both detection devices detect that the product is unqualified, the servo motor is controlled to drive the coiled material base belt to move backward to the first detection device for re-detection. If it is unqualified, it is repaired continuously. After repair, it moves forward and passes through the second detection device. If it is judged to be qualified, it continues to be transmitted. During this process, the servo motor controls the driving roller to rotate to drive the coiled material base belt to move forward or backward, avoiding the situation that the moving distance of the coiled material base belt is different due to the change of the coiled disk diameter, resulting in product dislocation after multiple movements. It can ensure that the moving distance of the coiled material base belt is consistent each time, thereby improving the transmission accuracy of the coiled material base belt, being beneficial to improving the position accuracy of the product, facilitating personnel detection and repair, and thus improving the overall detection and repair efficiency.

[0036] The first unwinding shaft 2 and the first winding shaft 4 are respectively rotatably installed on a box body 14 with a motor 11 arranged inside. Inside this box body 14 and on one side of the motor 11, a transmission rod 15 is arranged. The first unwinding shaft 2 and the first winding shaft 4 are fixedly connected to one end of the transmission rod 15. An abutting block 12 is sleeved on the outer wall of the other end of the transmission rod 15. The output shaft of the motor 11 is fixedly installed with an abutting block 16, and this abutting block 16 is in frictional contact with the abutting block 12, so that the output shaft of the motor 11 drives the transmission rod 15 to rotate. On the side of the above-mentioned abutting block 12 opposite to the abutting block 16 and on the outer wall of the above-mentioned transmission rod 15, a first nut 17 is threadedly connected. A first elastic member 18 is arranged between this first nut 17 and the abutting block 12. The movement of the coiled material base belt is realized by driving the driving roller to rotate through the servo motor. The first unwinding shaft and the second unwinding shaft are rotationally connected by being fixedly connected to the transmission rod inside the box body. An abutting block and a top block are arranged between the transmission rod and the output shaft of the motor. When the output shaft of the motor rotates, it drives the transmission rod to rotate through friction, so as to drive the first unwinding shaft and the second unwinding shaft to rotate. When the coiled material base belt changes direction, since the driving roller and the driven roller clamp the coiled material base belt, if the driving roller and the driven roller are not controlled in time, one end of the coiled material base belt will be clamped and the other end will be pulled, resulting in a taut state. If the motor continuously drives the first unwinding shaft and the second unwinding shaft to rotate, the abutting block on the output shaft of the motor will slide relative to the top block, thereby weakening the transmission force between the motor and the transmission rod, avoiding the situation that the excessive tension on the coiled material base belt caused by continuous driving causes the coiled material base belt to break, and thus ensuring the safety of the coiled material base belt.

[0037] A transmission piece 20 is arranged between the above-mentioned abutting block 16 and the top block 12.

[0038] A plurality of balls 21 are rotatably installed on the above-mentioned transmission piece 20, and a chute 22 matching the balls 21 is opened on the opposite sides of the above-mentioned top block 12 and the abutting block 16.

[0039] On the side of the first nut 17 opposite to the top block 12 and on the outer circumferential wall of the transmission rod 15, a second nut 19 is threadedly connected to prevent the first nut from moving along the length direction of the transmission rod under the extrusion force of the first elastic member.

[0040] The above-mentioned driving mechanism includes: a mounting frame 30, a cylinder 29 fixedly installed on the support frame 28, the driven roller 26 is rotatably installed inside the mounting frame 30, and the movable end of the cylinder 29 is fixedly connected to the mounting frame 30.

[0041] The above-mentioned detection device 201 includes: a light-transmitting plate 201 installed on the loading platform 1, a front telecentric camera 601 located above the light-transmitting plate 201, and the front telecentric camera 601 is connected to the computer mainframe 7; When the coiled material baseband is located on the light-transmitting plate, the detection device can detect the coiled material baseband, and the surface light source and the back light source are started to illuminate the coiled material baseband for supplementary lighting, so as to facilitate the front telecentric camera and the back telecentric camera to detect the coiled material baseband.

[0042] On one side of the front telecentric camera 601 and below the light-transmitting plate 201, a back telecentric camera 602 connected to the computer mainframe 7 is provided.

[0043] Above the above-mentioned first unwinding shaft 2, a second winding shaft 5 for winding the protective film tape is provided, and above the first winding shaft 4, a second unwinding shaft 3 for unwinding the protective film tape is provided.

[0044] The above-mentioned repair platform 101 includes: a second display screen 9 horizontally installed on the loading platform 1, and the second display screen 9 with the upper surface flush with the loading platform 1 is connected to the computer mainframe 7.

[0045] Further, its repair platform includes a second display screen horizontally installed on the loading platform, and the second display screen with the upper surface flush with the loading platform is connected to the computer mainframe. The first motor and the second motor are both forward and reverse motors. If it is still unqualified after being detected by the second front telecentric camera, the first motor and the second motor are controlled to reverse, driving the coiled material baseband to return to the first front telecentric camera for continued photographing and detection for re-inspection. If it is unqualified, it is repaired again, and the computer mainframe controls the second display screen to highlight the unqualified products, facilitating the personnel to quickly find the unqualified products for repair. If it is qualified, it continues to be transmitted forward, shortening the time for the personnel to find the unqualified products, and also realizing multiple detections and repairs of the products, greatly improving the overall maintenance efficiency; A surface light source 202 is respectively provided between the above-mentioned front telecentric camera 601 and the light-transmitting plate 201, and between the back telecentric camera 602 and the light-transmitting plate 201.

[0046] A backlight 203 is provided on one side of the above-mentioned light-transmitting plate 201 opposite to the surface light source 202.

[0047] A bearing 23 is provided between the above-mentioned shaft rod 13 and the box body 14.

[0048] The above-mentioned balls 21 are annularly distributed along the circumferential direction of the transmission piece 20, and the above-mentioned chute 22 is an annular chute.

[0049] The working principle is as follows: During use, the transfer film roll tape is sleeved on the first unwinding shaft, and one end of the transfer film roll is pulled out to separate the roll tape base and the protective film tape. The protective film tape is wound on the second winding shaft. The roll tape base passes between the driving roller and the driven roller and is transmitted on the loading platform. During the transmission process, the two detection devices can detect the roll tape base, and the defective roll tape base can be repaired on the repair platform. Then, the roll tape base is attached to the protective film tape on the second unwinding shaft and wound together on the first winding shaft; The first unwinding shaft, the first winding shaft, the second unwinding shaft, and the second winding shaft rotate through the box body. The motor inside the box body is connected to the transmission rod through the top block, the transmission piece, and the abutting block. The first nut on the transmission rod is rotated to adjust the compression amount of the elastic member, and further adjust the friction force between the top block, the abutting block, and the transmission piece. Rotating the second nut can prevent the first nut from rotating relatively due to the rotational movement of the transmission rod, realizing the locking of the first nut; When the roll tape base needs to be wound in the reverse direction, when the roll tape base is in a taut state, the balls are mutually pressed tightly by the top block and the abutting block to transmit the driving force of the motor between the top block and the abutting block, thereby driving the transmission rod to rotate in the reverse direction. If the pulling force of the roll tape base is too large, the chute provided on the surfaces of the top block and the abutting block slides with the balls inside the transmission piece, resulting in slipping between the top block, the transmission piece, and the abutting block, thereby losing the driving force for the transmission rod and avoiding the situation that the continuous rotation of the transmission rod causes the pulling force of the roll tape base to increase and the roll tape base to break; When the roll tape base is located on the light-transmitting plate, the detection device can detect the roll tape base, and the surface light source and the backlight are started to illuminate the roll tape base with supplementary light, so as to facilitate the detection of the roll tape base by the front telecentric camera and the back telecentric camera; During the movement of the roll tape base, first, the driving roller and the driven roller downstream clamp the roll tape base, and the driving roller is driven to rotate by the servo motor, thereby driving the roll tape base to move forward. During the movement of the roll tape base, the first detection device conducts the first detection, and then the roll tape base reaches the second detection device after passing through the repair platform, and the second detection device can conduct a re-inspection and comparison; Taking the first unwinding shaft as the upstream and the first rewinding shaft as the downstream, if the quality of the coiled material is qualified, the coiled material baseband continues to move for winding. If the quality of the coiled material baseband is unqualified, the cylinder downstream drives the mounting frame to move upward, causing the driving roller and the driven roller to separate. The first unwinding shaft, the first rewinding shaft, the second unwinding shaft, and the second rewinding shaft rotate in reverse. The cylinder upstream drives the mounting frame to move downward, causing the driving roller and the driven roller to contact, thereby driving the defective coiled material baseband to return to the first detection device for re-inspection. Then it moves to the repair platform. The data of the detection device is presented on the first display through the computer host, and the unqualified products are highlighted on the second display. The staff can then repair the unqualified products. After the repair is completed, the driving roller and the driven roller upstream separate, and the driving roller and the driven roller downstream contact, thereby driving the coiled material baseband to pass through the second detection device for detection again. If the detection is qualified, the coiled material baseband is wound up.

[0050] When using the above double-station coiled material vision inspection machine, by setting two groups of detection devices, the product is detected multiple times, and a repair platform is arranged between the two groups of detection devices. When the first detection device detects that the product is unqualified, the personnel repair the product on the repair platform, which can achieve multiple detections and repairs of the product, improving the qualification rate of the product. The servo motor controls the rotation of the driving roller to drive the coiled material baseband to move forward or backward, avoiding the situation of product misalignment after multiple movements caused by different moving distances of the coiled material baseband due to changes in the diameter of the coil. It can ensure that the moving distance of the coiled material baseband is consistent each time, thereby improving the transmission accuracy of the coiled material baseband, being beneficial to improving the position accuracy of the product, facilitating personnel detection and repair, and thus improving the overall detection and repair efficiency. Furthermore, when the direction of the coiled material baseband changes, since the driving roller and the driven roller clamp the coiled material baseband, if the driving roller and the driven roller are not controlled in time, one end of the coiled material baseband will be clamped and the other end will be pulled, resulting in a taut state. If the motor continuously drives the first unwinding shaft and the second unwinding shaft to rotate, it will cause the sliding between the abutting block and the top block on the output shaft of the motor, thereby weakening the transmission force between the motor and the transmission rod, avoiding the situation of excessive tension on the coiled material baseband caused by continuous driving resulting in the breakage of the coiled material baseband, and thus ensuring the safety of the coiled material baseband.
