Description

Technical Field

[0001] The invention relates to the technical field of optical defect detection, and in particular to an automatic defect detection production line for toilet head products. Background Art

[0002] In the production process of toilet products, the application of optical inspection technology has become an indispensable part of improving product quality and production efficiency. Optical inspection technology, with its high precision, non-contact and strong real-time characteristics, is widely used in many aspects such as surface defect detection, size measurement and quality control of toilet products;

[0003] During the inspection of toilet product surface defects on the production line, since the toilet products need to be transported sequentially through the conveyor belt to the optical inspection site for inspection, the two sides of the optical inspection site will be open. Although door curtains are used for covering on some production lines, the movable connection of the door curtains will cause the door curtains to fail to completely cover the two sides of the optical inspection site during the falling process, and gaps may be easily formed, allowing some external light sources to enter the optical inspection site through the gaps in the door curtains. This not only makes the optical inspection site susceptible to changes in external light, such as fluctuations in sunlight and workshop lighting, resulting in unstable light intensity received by the inspection equipment, thereby affecting the accuracy of the inspection results, but also reflected light and scattered light from the surrounding environment will also enter the inspection area, superimposed on the inspection light source, forming light pollution, interfering with the normal operation of the inspection equipment, and reducing the accuracy of toilet product surface defect detection.

[0004] Therefore, the present invention proposes an automatic defect detection production line for toilet head products to solve the above problems. Summary of the invention

[0012] As a further solution of the present invention: the lower end surface of the mounting frame is symmetrically rotatably connected to pulleys, one of the pulleys is fixedly connected to a driving motor, a belt is sleeved between the outer surfaces of the pulleys, the outer surface of the belt is fixedly connected to a linkage frame, the lower end surface of the linkage frame is rotatably connected to a connecting shaft, and the connecting shaft is fixedly connected to the upper end surface of the rack plate.

[0013] As a further solution of the present invention: a connecting frame is fixedly connected between the same sides of the two shading plates, a dial plate is fixedly connected to one of the connecting frames close to the power switch, and the dial plate and the power switch are on the same vertical horizontal line.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a toilet head product defect automatic detection production line, which has the following beneficial effects:

[0019] 1. By setting up a light source blocking mechanism, the two sides of the optical inspection room can be automatically opened intermittently during the transportation of toilet products, and after the toilet products are moved into the optical inspection room, the two sides can be closed to block the external light source from entering the optical inspection room. It can not only effectively isolate the interference of external light (such as sunlight, workshop lighting, etc.), ensure that the light received by the detection equipment only comes from the detection light source, avoid the problem of unstable light intensity, thereby improving the accuracy and reliability of the detection results, but also avoid the situation where the external light source and the detection light source overlap to form light pollution, thereby improving the accuracy of the optical inspection room in detecting surface defects of toilet products.

[0020] 2. Through the setting of the connecting frame and the dial plate, the power switch can be synchronously turned on and off to open and close the movement of the production conveyor roller during the process of the shading plates on both sides being raised, lowered, opened and closed. This not only realizes the automatic linkage between the shading plates and the production conveyor rollers, but also eliminates the need to use additional drive equipment to control the operation and closing of the production conveyor rollers, thereby improving the automation level of the toilet product inspection production line. Moreover, the automated control enables the opening and closing of the shading plates and the starting and stopping of the production conveyor rollers to be precisely synchronized, thereby optimizing the timing and efficiency of the entire inspection process.

[0021] 3. By setting up the product limiting mechanism, while the shading plates on both sides descend to block the light source of the optical inspection room, the limiting plates inside the optical inspection room can be synchronously driven closer to each other, and the toilet product can be pushed to the center of the optical inspection room. This is not only conducive to the optical inspection room to shoot or scan from the best angle, thereby improving the clarity and accuracy of the image or data, so as to more accurately identify defects on the surface of the toilet product, but also there is no need to manually adjust the position of the toilet product. The automatic push saves time and improves the consistency and efficiency of the inspection process.

[0022] 4. By setting up the slider and spring, after the limit plate contacts different toilet products, as the limit plate is continuously pressured, it will be converted into pushing the slider to move and squeeze the spring, so that the limit plate can adapt to different toilet products. This not only improves the compatibility of the optical inspection room with different types of toilet products, but also eliminates the need to design separate fixtures for each size of toilet product, thereby reducing production costs and complexity. In addition, by automatically adjusting the position of the limit plate, it can ensure that the toilet product is always in the center of the inspection area, thereby improving the shooting or scanning accuracy of the inspection equipment and reducing the inspection error caused by position deviation.

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] A toilet head product defect automatic detection production line of this embodiment, such as Figure 1 - Figure 8 As shown, it includes a production conveyor roller 1, the upper end surface of the production conveyor roller 1 is fixedly connected to an optical inspection chamber 2, the side wall of the production conveyor roller 1 is fixedly connected to a power switch 6, the upper end surface of the optical inspection chamber 2 is fixedly connected to a mounting frame 5, and the optical inspection chamber 2 is provided with a light source blocking mechanism, which is used to block external light sources from entering the optical inspection chamber 2.

[0038] In this embodiment, Figure 1 and Figure 3 As shown, the light source blocking mechanism includes symmetrically arranged shading plates 301, which are vertically slidably connected to both sides of the optical detection chamber 2, and the side of the shading plates 301 away from the optical detection chamber 2 is rotatably connected to a connecting plate 302, and the end of the connecting plate 302 away from the shading plates 301 is rotatably connected to a linkage plate 303, and a rotating shaft 304 is fixedly connected between the two linkage plates 303. The outer surface of the rotating shaft 304 is symmetrically rotatably connected to a support block 305, and the support block 305 is fixedly connected to the upper end surface of the optical detection chamber 2. When the rotating shaft 304 drives the linkage plates 303 on both sides to rotate, the linkage plate 303 will drive the shading plates 301 to rise and fall on the side wall of the optical detection chamber 2 through the connecting plate 302.

[0039] In this embodiment, Figure 3 and Figure 4 As shown, a transmission gear 308 is fixedly connected at the center of the outer surface of the rotating shaft 304, a rack plate 309 is meshed and connected above the transmission gear 308, a slide plate 311 is symmetrically fixedly connected to the upper end surface of the rack plate 309, and the slide plates 311 are horizontally slidably connected to the lower end surface of the mounting frame 5. When the rack plate 309 slides on the lower end surface of the mounting frame 5 through the slide plate 311, the transmission gear 308 below will be driven to drive the rotating shaft 304 to rotate synchronously.

[0040] In this embodiment, Figure 4 and Figure 5As shown, the lower end surface of the mounting frame 5 is symmetrically connected to a pulley 310 for rotation, one of the pulleys 310 is fixedly connected to a driving motor, a belt 312 is sleeved between the outer surfaces of the pulleys 310, the outer surface of the belt 312 is fixedly connected to a linkage frame 313, the lower end surface of the linkage frame 313 is rotatably connected to a connecting shaft 314, and the connecting shaft 314 is fixedly connected to the upper end surface of the rack plate 309. When the driving motor drives one of the pulleys 310 to rotate, the belt 312 can move around the two pulleys 310 through the other pulley 310. When the linkage frame 313 follows the belt 312 to move horizontally, the linkage frame 313 will drive the rack plate 309 to move synchronously through the connecting shaft 314. When the linkage frame 313 follows the belt 312 to move around the pulley 310, the linkage frame 313 will rotate synchronously around the connecting shaft 314, and the initial rack plate 309 will not move.

[0041] In this embodiment, Figure 1 and Figure 2 As shown, a connecting frame 306 is fixedly connected between the same sides of the two shading plates 301, and a dial plate 307 is fixedly connected to one of the connecting frames 306 close to the power switch 6. The dial plate 307 and the power switch 6 are on the same vertical level. When the shading plate 301 drives the connecting frame 306 to rise and fall, the dial plate 307 can toggle the power switch 6 to turn it on and off.

[0042] In the prior art, since toilet products need to be transported sequentially through the conveyor belt to pass through the optical inspection location for inspection, the two sides of the optical inspection location are in an open state, which not only makes the optical inspection location susceptible to changes in external light, such as fluctuations in sunlight and workshop lighting, resulting in unstable light intensity received by the detection equipment, thereby affecting the accuracy of the detection results, but also the reflected light, scattered light, etc. from the surrounding environment will enter the detection area, superimposed on the detection light source, forming light pollution, interfering with the normal operation of the detection equipment, and reducing the accuracy of the detection of surface defects of toilet products. Compared with the prior art, the two sides of the optical inspection chamber 2 can be intermittently opened automatically during the transportation of the toilet product, and after the toilet product is moved into the optical inspection chamber 2, the two sides are closed to block external light sources from entering the optical inspection chamber 2. Not only can the interference of external light (such as sunlight, workshop lighting, etc.) be effectively isolated, ensuring that the light received by the detection equipment only comes from the detection light source, avoiding the problem of unstable light intensity, thereby improving the accuracy and reliability of the detection results, but also avoiding the situation where the external light source and the detection light source are superimposed to form light pollution, thereby improving the accuracy of the optical inspection chamber 2 in detecting surface defects of toilet products.

[0043] In other aspects, this embodiment also provides a product limiting mechanism for pushing the product inside the optical inspection chamber 2 to a specified position, such as Figure 1 , Figure 6 - Figure 8 As shown, the product limiting mechanism includes a symmetrically arranged T-shaped plate 402, and the T-shaped plate 402 is symmetrically fixedly connected with a sliding column 403 on one side close to the optical inspection chamber 2. The sliding column 403 is slidably connected to the optical inspection chamber 2, and a limiting plate 404 is fixedly connected between the ends of the two sliding columns 403 on the same side away from the T-shaped plate 402.

[0044] In this embodiment, Figure 7 and Figure 8 As shown, the lower end surface of the T-shaped plate 402 is provided with a sliding groove 406, and a slider 405 is slidably connected in the sliding groove 406. The lower end surface of the slider 405 is rotatably connected with a push plate 401, and the end of the push plate 401 away from the slider 405 is rotatably connected to the upper end surface of the connecting frame 306. When the connecting frame 306 is raised or lowered, the push plate 401 will push the slider 405 to slide synchronously in the sliding groove 406. When the slider 405 is limited, after the slider 405 is pushed, it will push the T-shaped plate 402 to move.

[0045] In this embodiment, Figure 8 As shown, springs 407 are fixedly connected to the side walls of the slider 405, and one end of the spring 407 away from the slider 405 is fixedly connected to the inner wall of the slide groove 406. When the slider 405 is obstructed, it will slide in the slide groove 406 and pull the spring 407 to extend.

[0046] Compared with the prior art, while the shading plates 301 on both sides descend to block the light source of the optical inspection chamber 2, the limit plates 404 inside the optical inspection chamber 2 can be synchronously driven to approach each other, and the toilet product can be pushed to the center of the optical inspection chamber 2. This is not only conducive to the optical inspection chamber 2 to shoot or scan from the best angle, thereby improving the clarity and accuracy of the image or data, so as to more accurately identify defects on the surface of the toilet product, but also eliminates the need for manual adjustment of the position of the toilet product. The automatic push saves time and improves the consistency and efficiency of the inspection process.

[0047] The working process and principle involved in the overall content of the above embodiment are as follows:

[0048] When the staff needs to inspect the surface of the toilet product, they first turn on the driving motor connected to one of the pulleys 310 to drive the pulley 310 to rotate. At this time, through the belt 312 set between the outer surfaces of the two pulleys 310, when one of the pulleys 310 rotates, it can drive the other pulley 310 to rotate synchronously, and the driving belt 312 moves around the two pulleys 310. With the movement of the belt 312, the belt 312 will drive the linkage frame 313 connected to the outer surface to move horizontally first, and then the linkage frame 313 will move downward. The connecting shaft 314 connected to the end face rotates and drives the rack plate 309 below to move synchronously. Since the upper end face of the rack plate 309 is symmetrically connected to the slide plate 311, and the slide plate 311 is slidably connected to the lower end face of the mounting frame 5, when the rack plate 309 is moved, it will move horizontally synchronously at the lower end of the mounting frame 5, and through the meshing connection between the rack plate 309 and the transmission gear 308, the rotating shaft 304 connected to the transmission gear 308 is driven to rotate on the two support blocks 305 (it should be noted that the number of teeth on the lower end face of the rack plate 309 is adapted to the transmission gear 308). The number of teeth on the outer surface of the rotating gear 308 in one circle drives the linkage plates 303 connected to the two ends of the rotating shaft 304 to rotate synchronously. When the rotating shaft 304 drives the linkage plate 303 to rotate in the first half of the circle, the end of the linkage plate 303 away from the rotating shaft 304 will rotate from the bottom of the rotating shaft 304 to the top of the rotating shaft 304, and pull one end of the connecting plate 302 to move synchronously around the rotating shaft 304. As one end of the connecting plate 302 moves with the linkage plate 303, the connecting plate 302 will pull the shading plates 301 on both sides of the optical detection chamber 2 to rise synchronously, and the shading plates 301 on both sides of the optical detection chamber 2 will move synchronously. During the rising process of the plate 301, the connecting frame 306 connected between the shading plates 301 will rise synchronously. Since a dial plate 307 is connected to the side wall of one of the connecting frames 306, and the dial plate 307 and the power switch 6 are on the same vertical horizontal line, during the rising process of the connecting frame 306, the dial plate 307 will be driven to rise and contact the power switch 6, and the dial plate 307 will turn the power switch 6 on, so that the production conveying roller 1 will work, and the toilet products will be conveyed to the optical inspection room 2 during the rising process of the shading plates 301 on both sides;

[0049] When the connecting frame 306 rises and drives the dial plate 307 to turn on the power switch 6, the connecting frame 306 will push the lower end of the push plate 401 connected to the upper end surface to rise synchronously, so that the push plate 401 moves from an inclined state to a horizontal state. As the state of the push plate 401 changes, the push plate 401 will push the slider 405 to slide synchronously in the slide groove 406 opened on the lower end surface of the T-shaped plate 402. Since a spring 407 is connected between the slider 405 and the slide groove 406, the slider 405 pushes the T-shaped plate 402 to move horizontally away from the optical detection chamber 2 through the spring 407, and drives the slide column 403 to slide out of the optical detection chamber 2, and drives the two limit plates 404 in the optical detection chamber 2 to move away from each other, so that the production conveying roller 1 can convey the toilet product to between the limit plates 404;

[0050] When the shaft 304 drives the linkage plate 303 to rotate the second half of the circle, the end of the linkage plate 303 away from the shaft 304 will rotate from the top to the bottom again. At this time, the linkage plate 303 will push the shading plate 301 to slide downward on the side wall of the optical inspection chamber 2 through the connecting plate 302, and close both sides of the optical inspection chamber 2 to block the external light source from entering the optical inspection chamber 2. It can not only effectively isolate the interference of external light (such as sunlight, workshop lighting, etc.), ensure that the light received by the detection equipment comes only from the detection light source, avoid the problem of unstable light intensity, thereby improving the accuracy and reliability of the detection result, but also avoid the situation where the external light source and the detection light source overlap to form light pollution, thereby improving the accuracy of the optical inspection chamber 2 in detecting surface defects of toilet products;

[0051] During the descent of the shading plate 301, the shading plate 301 drives the connecting frames 306 on both sides to descend synchronously, and the connecting frames 306 drive the dial plate 307 connected to the side wall to move downward again, and the power switch 6 is turned in the opposite direction to shut down the movement of the production conveyor roller 1. At this time, the production conveyor roller 1 has conveyed the toilet product to the optical inspection room 2, which not only realizes the automatic linkage between the shading plate 301 and the production conveyor roller 1, but also eliminates the need to use additional drive equipment to control the operation and shutdown of the production conveyor roller 1, thereby improving the automation level of the toilet product inspection production line. In addition, the automatic control enables the opening and closing of the shading plate 301 and the starting and stopping of the production conveyor roller 1 to be precisely synchronized, thereby optimizing the timing and efficiency of the entire inspection process.

[0052] During the process of the connection frame 306 descending, the connection frame 306 will pull the lower end of the push plate 401 downward again, so that the push plate 401 moves from a horizontal state to an inclined state. As the state of the push plate 401 changes, the push plate 401 will pull the T-shaped plate 402 to approach the optical inspection chamber 2 again through the slider 405 and the spring 407, and push the slide column 403 to slide into the optical inspection chamber 2, so that the two limit plates 404 in the optical inspection chamber 2 move closer to each other, and push the toilet product to the center of the optical inspection chamber 2, which is not only conducive to the optical inspection chamber 2 to shoot or scan from the best angle, thereby improving the clarity and accuracy of the image or data, so as to more accurately identify the defects on the surface of the toilet product, but also does not need to manually adjust the position of the toilet product. The automatic push saves time and improves the consistency and efficiency of the inspection process.

[0053] When the limiting plates 404 on both sides contact the toilet product and are pushed to the center, as the connecting frame 306 continues to descend, the connecting frame 306 will pull the slider 405 through the push plate 401 to slide in the slide groove 406 opened on the lower end surface of the T-shaped plate 402, and pull the spring 407 connected between the slider 405 and the slide groove 406, and will not push the T-shaped plate 402, the slide column 403 and the limiting plate 404 to slide, so that the limiting plate 404 can adapt to different toilet products, which not only improves the compatibility of the optical inspection room 2 with different types of toilet products, but also does not need to design a separate fixing device for each size of toilet product, reducing production costs and complexity, and by automatically adjusting the position of the limiting plate 404, it can ensure that the toilet product is always in the center of the inspection area, thereby improving the shooting or scanning accuracy of the inspection equipment and reducing the inspection error caused by position deviation;

[0054] When the belt 312 drives the rack plate 309 to move from one side above the transmission gear 308 to the other side through the linkage frame 313 and the connecting shaft 314, the rack plate 309 will drive the transmission gear 308 to rotate synchronously for one circle. As the connecting frame 306 continues to move following the belt 312, the belt 312 will drive the connecting frame 306 from horizontal movement to rotational movement around the center of the pulley 310. At this time, the connecting shaft 314 will follow the rack plate 309 to move to the center directly below the pulley 310, and the connecting frame 306 and the connecting shaft 314 are rotatably connected. Therefore, when the linkage frame 313 follows the belt 312 to rotate around the pulley 310, it will rotate at the upper end of the connecting shaft 314 and will not drive the rack plate 309 to move. In the gap where the rack plate 309 has not moved, the optical inspection chamber 2 can complete the inspection of the internal toilet product surface.
