Description

Technical Field

[0001] This invention relates to the field of sticker laminating machines, and more particularly to an automated sticker laminating machine for vehicle rearview mirror glass lenses and its control method. Background Technology

[0002] As an indispensable safety component during vehicle operation, rearview mirrors have explosion-proof paper applied to their glass lenses. This not only effectively prevents the glass from shattering and injuring people, thus improving driving safety, but also provides scratch and wear resistance and enhances the clarity of the mirror.

[0003] In the traditional rearview mirror manufacturing process, the application of explosion-proof paper is mostly done manually. During this manual application process, factors such as the operator's skill level and fatigue can easily lead to problems like misaligned application, air bubbles, and poor edge adhesion, affecting the final quality and appearance of the rearview mirror. Furthermore, manual operation is inefficient and cannot meet the growing demands of large-scale production in the automotive industry, increasing both labor and time costs for businesses. Summary of the Invention

[0004] In order to improve the quality and production efficiency of the finished product after applying film to rearview mirrors, this invention provides an automated sticker coating machine for vehicle rearview mirror glass lenses and its control method.

[0005] In a first aspect, the present invention provides an automated sticker coating machine for vehicle rearview mirror glass lenses, employing the following technical solution: An automated sticker coating machine for vehicle rearview mirror glass lenses includes a conveyor belt for conveying the glass lenses, and further includes: The pressure plate, having a sticker gap between itself and the conveyor belt for the glass lens to pass through, is elastic and is used to press against the glass lens and attach the explosion-proof paper to the glass lens; Adjust the base for mounting the pressure plate, and adjust the horizontal position of the pressure plate and the height of the sticker gap; Paper feeding mechanism, used to install and release paper tape with explosion-proof paper attached; The paper collection mechanism is used to pull and rewind the paper strip after the stickers have been applied. The paper receiving mechanism pulls the paper strip out from the paper dispensing mechanism and through the sticker gap, the explosion-proof paper separates from the paper strip in the sticker gap, and the pressing plate abuts against the glass lens to stick the explosion-proof paper on the surface of the paper strip onto the glass lens; A sensor is provided at the bottom of the pressure plate. The sensor is electrically connected to the paper receiving mechanism and is used to control the paper receiving mechanism to intermittently pull the paper strip when the glass lens passes through the gap of the sticker.

[0006] By adopting the above technical solution, the glass lens is placed on a conveyor belt, which transports the glass lens. The two ends of a paper strip with explosion-proof paper attached are connected to the paper feeding mechanism and the paper receiving mechanism, respectively, and the strip passes over a pressure plate. When the motor in the paper receiving mechanism runs, it is pulled by the paper strip. As the glass lens passes through the gap in the paper strip, the pressure plate affixes the explosion-proof paper to the glass lens. This process requires no manual operation; the operator only needs to place the glass lens on the conveyor belt. Compared to manual paper application, this method produces higher quality glass lenses and has higher production efficiency.

[0007] Optionally, the paper delivery mechanism includes a take-up roller, a traction roller, a pressure roller, and a drive assembly; the take-up roller and the traction roller are both connected to the drive assembly and are synchronously driven by the drive assembly to provide traction force to the paper strip; the pressure roller is rotatably disposed relative to the traction roller and presses against the traction roller, the paper strip passes between the pressure roller and the traction roller, and the surface of the pressure roller has anti-slip texture.

[0008] By adopting the above technical solution, each time the drive component pulls the paper tape, the pressure roller can press the paper tape firmly onto the traction roller, making the paper tape less prone to loosening, thereby ensuring the accuracy of the paper being pasted on the glass lens at the pressure plate.

[0009] Optionally, the paper feeding mechanism includes a mounting plate for mounting the paper tape, which is rotatably mounted on the adjusting base; a plurality of guide rollers for guiding the direction of the paper tape; and a stress-relieving assembly. The stress-relieving assembly includes an adjusting roller component rotatably mounted on the adjusting base and around which the paper tape passes, and a reset torsion spring. The reset torsion spring is disposed between the adjusting roller component and the adjusting base and is used to drive the adjusting roller component to always have the tendency to tighten the paper tape to release the paper tape from the mounting plate.

[0010] By adopting the above technical solution, because there is a certain attraction between the paper tapes when they are wound on the mounting plate, the mounting plate cannot rotate immediately and release the paper tape. Therefore, the paper tape will first pull the adjusting roller to swing a certain distance. When the drive component stops running, the rotating plate slowly releases the paper tape under the action of the reset torsion spring, and the adjusting roller resets at the same time. The above structure can ensure that the paper tape is not easily broken.

[0011] Optionally, the adjustment base includes a base plate for mounting the pressure plate, a horizontal adjustment assembly for driving the base plate to perform horizontal displacement adjustment, and a height adjustment assembly for driving the base plate to perform height displacement adjustment; the height adjustment assembly includes a vertical screw, a height adjustment block threaded to the vertical screw, and a connecting block sleeved on the vertical screw and located at the top of the height adjustment block; the base plate is connected to the connecting block; a pressure spring is provided between the connecting block and the height adjustment block.

[0012] By adopting the above technical solution, the entire substrate is movably mounted on the adjustment base, so that the distance between the pressure plate and the conveyor belt can be adaptively adjusted.

[0013] Secondly, this application provides a control method for an automated sticker coating machine for vehicle rearview mirror glass lenses, employing the following technical solution: A control method for an automated sticker coating machine for vehicle rearview mirror glass lenses, applied to such an automated sticker coating machine, includes: Capture images of the glass lens placement as it is placed on the conveyor belt; The lens placement position is determined based on the lens placement image and preset reference points; The lens and the sticker laminating machine are synchronously calibrated according to the lens placement position using a preset center calibration method, and the presence of mirror impurity features is determined based on the lens placement image recognition. When there are impurities on the lens, the preset cleaning mechanism is controlled by the preset lens cleaning method to clean the lens using a paper strip with the sticker already applied. After a preset delivery time, the sticker laminating machine is controlled to apply stickers to the glass lens using a preset sticker application method via a pressure plate.

[0014] Optionally, a preset initial alignment distance is used to control the pusher plate on the conveyor belt to push the glass lens at the lens placement position, so as to align most of the glass lenses and acquire the corrective lens image after distance adjustment. Identify the position of the corrective lens from the corrective lens image; Determine the actual delivery path of the corrective lens based on its position; Analyze whether the actual lens delivery path matches the preset alignment delivery path; When the actual transport path of the lens is inconsistent with the alignment transport path, calculate the path deviation between the actual transport path and the alignment transport path. The base is adjusted horizontally to fine-tune the pressure plate based on the path deviation control.

[0015] By adopting the above technical solution, the push plate and the pressure plate are combined for synchronous adjustment. First, most of the glass lenses are pushed and aligned by the push plate, rather than pressing all the glass lenses against the conveyor belt edge at once. This avoids the glass lenses getting stuck between the push plate and the conveyor belt edge, preventing them from moving properly. After most of the glass lenses are aligned, the alignment of the remaining lenses is corrected by adjusting the horizontal displacement of the pressure plate. The entire process is highly efficient.

[0016] Optionally, methods for identifying specular impurity features include: The position of the light source is determined based on the placement of the lens and the preset camera shooting position; Illuminate the glass lens at the location of the light source and identify the reflective areas of the lens from the image of the lens placement; Identify the color characteristics of areas reflected in the lens; Determine whether the region's color features include a preset shadow color; When a shadow color is present, a specular impurity feature is defined. The specular impurity feature is identified from the lens placement image to determine the adhesion distance and height of the impurity along the transmission direction. Output adhesion distance and impurity height.

[0017] By adopting the above technical solution, the glass lens is illuminated by a light source to generate reflection, and then the mirror surface of the reflective glass lens is identified. At this time, the impurities on the mirror surface can have obvious color differences due to the highlights and shadows, making it easier to determine whether there are impurities on the mirror surface from the image.

[0018] Optionally, the cleaning mechanism includes a cleaning pressure plate and a spray head; the lens cleaning method includes: Control the spray head to spray a preset soapy water mist onto the surface of the paper tape that bypasses the cleaning pressure plate, and collect the lens update position in real time; When the lens replacement position coincides with the preset cleaning position, the cleaning plate is controlled by a preset rotation angle to press against the surface of the glass lens, so that the cleaning plate slides off the surface of the glass lens as the glass lens moves on the conveyor belt. When there are mirror impurities on the surface of the glass lens, the lifting time of the cleaning plate is determined according to the adhesion distance and the preset conveyor belt speed. The correction angle of the cleaning plate is matched according to the height of the impurities; When the glass lens comes into contact with the cleaning plate, and after the lifting time, the cleaning plate is rotated by the correction angle control, and after the preset movement time, the cleaning plate is reset by the rotation angle control.

[0019] By adopting the above technical solution, the paper tape that has already been covered with explosion-proof paper can be reused. Since the areas on the paper tape where the explosion-proof paper was originally applied are relatively smooth and clean after the paper is peeled off, it can be used to clean the surface of glass lenses. Furthermore, spraying soapy water mist onto the paper tape gives it a certain degree of adhesion. When the glass lens passes over the cleaning platen, the paper tape that bypasses the platen removes impurities from the glass lens surface and leaves soapy water on the surface, making the glass lens adhere better during subsequent paper application due to the presence of soapy water.

[0020] Optional sticker methods include: Real-time acquisition of sensor detection signals; When the sensor detects a signal of 1, a preset drive signal is output after a preset approach time. The motor drive angle is matched according to the preset lens diameter; The motor drive speed is matched according to the preset conveyor belt conveying speed; The drive motor is started by controlling the drive signal, and the drive motor is rotated by controlling the drive angle and drive speed of the motor to stick the explosion-proof paper on the surface of the glass lens, and the image of the sticker on the glass lens is captured. Determine whether the glass lens has been properly stickered based on the sticker image; When the glass lens is coated, the height of the roller is set according to the preset lens thickness. Adjust the preset roller height to press the roller onto the surface of the glass lens after the sticker is applied and smooth the explosion-proof paper.

[0021] Optional methods for handling incomplete sticker application on glass lenses include: The paper strip length between the preset pressure plate and the preset cleaning plate is matched to the spacing between the glass lens to be stickered and the glass lens to be cleaned. The preset lever is used to move the glass lens to be cleaned according to the interval distance; After cleaning the glass lens to be cleaned, match the overall moving distance according to the lens diameter; The overall movement distance is controlled by the preset displacement mechanism to move the sticker laminating machine as a whole, and the pressure plate is re-controlled to apply the sticker to the glass lens to be stickered. At the same time, the cleaning pressure plate is controlled to apply the missed explosion-proof paper to the cleaned glass lens. After the stickers are applied to both glass lenses, the sticker laminating machine is reset.

[0022] By adopting the above technical solution, when the explosion-proof paper fails to be correctly applied to the surface of the glass lens, the old explosion-proof paper is pulled to the cleaning pressure plate. At this time, the overall position of the sticker laminating machine is adjusted so that the new explosion-proof paper can be reapplied to the glass lens that has not been properly applied, while the old explosion-proof paper can be reapplied to the glass lens that has just been cleaned through the cleaning pressure plate, thus avoiding waste of explosion-proof paper.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the glass lens on a conveyor belt, which transports the glass lens. Connect both ends of a paper strip with explosion-proof paper attached to the paper feeding mechanism and the paper receiving mechanism, respectively, and pass over the pressure plate. When the motor in the paper receiving mechanism is running, it can be pulled by the paper strip and moved. At this time, when the glass lens passes through the gap of the paper strip, the pressure plate can attach the explosion-proof paper to the glass lens. The above process does not require manual operation. The operator only needs to place the glass lens on the conveyor belt. Compared with the manual paper attaching method, the above method produces glass lenses of higher quality and with higher production efficiency. 2. The paper tape that has already been covered with explosion-proof paper can be reused. Since the areas where the explosion-proof paper was originally applied are relatively smooth and clean after peeling, they can be used to clean the surface of glass lenses. Spraying soapy water mist onto the paper tape gives it some adhesion. When the glass lens passes over the cleaning platen, the paper tape that bypasses the platen removes impurities from the glass lens surface, and the soapy water on the surface makes the glass lens adhere better during subsequent paper application. 3. When the explosion-proof paper fails to adhere correctly to the glass lens surface, the old explosion-proof paper is pulled to the cleaning pressure plate. At this time, the overall position of the sticker laminating machine is adjusted so that the new explosion-proof paper can be re-attached to the glass lens that has not yet been stickered, while the old explosion-proof paper can be re-attached to the glass lens that has just been cleaned through the cleaning pressure plate, thus avoiding waste of explosion-proof paper.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] This application discloses an automated sticker coating machine for vehicle rearview mirror glass lenses.

[0028] Reference Figure 1 An automated sticker-applying machine for vehicle rearview mirror glass lenses includes an adjusting base 1, a paper feeding mechanism 2, a paper receiving mechanism 3, a pressure plate 4, a sensor, and a conveyor belt 5. The paper feeding mechanism 2, the paper receiving mechanism 3, and the pressure plate 4 are all mounted on the adjusting base 1. When applying the sticker to the glass lens, the lens is placed on the conveyor belt 5, and the lens moves with the conveyor belt 5. A paper strip with explosion-proof paper is wound around the paper feeding mechanism 2. One end of the paper strip is pulled out, passes over the pressure plate 4, and is mounted on the paper receiving mechanism 3. The paper receiving mechanism 3 can pull and retract the paper strip. When the glass lens moves under the pressure plate 4, the pressure plate 4 presses down on the glass lens, and the sensor below the pressure plate 4 detects the glass lens. At this time, the pressure plate 4 can affix the explosion-proof paper to the glass lens.

[0029] In this embodiment, the pressure plate 4 is a thin, elastic metal sheet. A sticker gap exists between the pressure plate 4 and the conveyor belt 5, allowing the glass lens to pass through. Because the pressure plate 4 is elastic, it applies force to the glass lens as it passes through the sticker gap without obstructing its passage. The end of the pressure plate 4 near the conveyor belt 5 has fine metal filaments that lift the explosion-proof film from the paper strip surface.

[0030] Reference Figure 1 and Figure 2 An adjusting base 1 is installed on one side of the conveyor belt 5. The adjusting base 1 includes a base plate 11, a horizontal adjusting component 12, and a height adjusting component 13. The paper feeding mechanism 2, the paper receiving mechanism 3, and the pressure plate 4 are all installed on the base plate 11. The horizontal adjusting component 12 is used to adjust the horizontal position of the pressure plate 4 so that the explosion-proof paper can be centered and affixed to the glass lens. The height adjusting component 13 is used to adjust the height of the sticker gap so that the glass lens can pass through the sticker gap more easily and the sticker can be affixed.

[0031] The height adjustment assembly 13 includes a vertical screw 131, a height adjustment block 132, a connecting block 133, and a first guide rod 134. The height adjustment block 132 is threaded to the outside of the vertical screw 131, and the connecting block 133 is sleeved on the outside of the vertical screw 131 and located above the height adjustment block 132. A pressure spring 135 is provided between the height adjustment block 132 and the connecting block 133. The first guide rod 134 is arranged parallel to the vertical screw 131, and both are vertically arranged. The first guide rod 134 vertically passes through the height adjustment block 132 and the connecting block 133.

[0032] The vertical screw 131 has a first turntable 136 at its top. Rotating the first turntable 136 drives the vertical screw 131 to rotate. The height adjustment block 132 can move vertically up and down on the vertical screw 131, thereby driving the connecting block 133 to move up and down. The first guide rod 134 can guide the vertical movement of the connecting block 133.

[0033] The horizontal adjustment assembly 12 includes a horizontal screw 121 and a second guide rod 122, which are arranged in parallel. A connecting block 133 is horizontally inserted through both the horizontal screw 121 and the second guide rod 122, and the connecting block 133 is threadedly connected to the horizontal screw 121. The base plate 11 is rotatably connected to the horizontal screw 121 and fixedly connected to the second guide rod 122. The end of the horizontal screw 121 has a second turntable 123. Rotating the second turntable 123 drives the horizontal screw 121 to rotate. Because the connecting block 133 restricts rotation, the horizontal screw 121 can extend and retract, thereby moving the base plate 11 horizontally. The second guide rod 122 guides the horizontal movement of the base plate 11.

[0034] Reference Figure 1 and Figure 3 The paper take-up mechanism 3 is used to pull and rewind the paper strip after it has been pasted. The paper take-up mechanism 3 includes a take-up roller 31, a traction roller 32, a pressure roller 33, a fixing frame 34, and a drive assembly 35. The take-up roller 31, traction roller 32, pressure roller 33, and fixing frame 34 are all rotatably mounted on the side of the base plate 11 near the conveyor belt 5, and the drive assembly 35 is mounted on the side of the base plate 11 away from the conveyor belt 5.

[0035] Reference Figure 2 and Figure 3 The drive assembly 35 includes a drive motor 351, a drive wheel 352, a first driven wheel 353, a second driven wheel 354, a tension wheel 355, and a synchronous belt 356. The drive wheel 352 is connected to the output end of the drive motor 351. The tension wheel 355 is slidably mounted on the base plate 11. The first driven wheel 353 and the second driven wheel 354 are both rotatably mounted on the base plate 11. The synchronous belt 356 is sleeved on the outside of the drive wheel 352, the first driven wheel 353, the second driven wheel 354, and the tension wheel 355. When the drive motor 351 rotates, the drive wheel 352, the first driven wheel 353, the second driven wheel 354, and the tension wheel 355 can rotate synchronously.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The traction roller 32 is fixedly connected to the rotation shaft of the first driven wheel 353. A fixing frame 34 is sleeved on the outside of the rotation shaft of the first driven wheel 353 and fixedly connected to the base plate 11. The fixing frame 34 includes a support frame 341 and a rotating plate 342 rotatably mounted on the support frame 341. The pressure roller 33 has anti-slip textures on its surface and is rotatably mounted on the rotating plate 342. A pressure spring 343 is provided between the rotating plate 342 and the support frame 341, pressing the pressure roller 33 against the traction roller 32. The take-up roller 31 is fixedly connected to the rotation shaft of the second driven wheel 354.

[0037] The paper strip passes between the traction roller 32 and the pressure roller 33 and is wound around the take-up roller 31. When the drive motor 351 rotates, the traction roller 32 and the take-up roller 31 rotate synchronously, thereby applying a traction force to the paper, causing the paper to be pulled and wound around the take-up roller 31. Because the pressure roller 33 presses against the surface of the traction roller 32, the paper strip is not easily loosened when the motor stops because it is clamped by the pressure roller 33 and the traction roller 32.

[0038] In this embodiment, the drive motor 351 is electrically connected to the sensor below the pressure plate 4. When the sensor detects the glass lens, the drive motor 351 starts running; therefore, in this embodiment, the drive motor 351 operates in an intermittent mode.

[0039] Reference Figure 2 , Figure 3 and Figure 5The paper feeding mechanism 2 includes a mounting plate 21, guide rollers 22, and a stress-relieving assembly 23. Both the mounting plate 21 and the guide rollers 22 are rotatably mounted on the base plate 11. Multiple guide rollers 22 are used to guide the movement direction of the paper tape, while the mounting plate 21 is used to mount new paper tape. The stress-relieving assembly 23 includes an adjusting roller component 231 and a return torsion spring 232. The adjusting roller component 231 further includes a swing arm rotatably mounted on the base plate 11 and an adjusting roller rotatably mounted on the swing arm. When the swing arm rotates on the base plate 11, the adjusting roller can swing on the base plate 11. The return torsion spring 232 is installed between the swing arm and the base plate 11, driving the adjusting roller to always tend to tighten the paper tape.

[0040] The new paper tape is installed on the mounting plate 21. One end of the paper tape exits the mounting plate 21, wraps around the adjusting roller once, and, guided by the guide roller 22, passes over the end of the pressure plate 4 before being pulled by the take-up mechanism 3. When the drive motor 351 of the take-up mechanism 3 rotates at a certain angle, the paper tape is pulled and moves a certain distance. Because there is a certain adhesion between the paper tapes when they are wrapped around the mounting plate 21, the mounting plate 21 cannot rotate immediately and release the paper tape. Therefore, the paper tape will first pull the adjusting roller to swing a certain distance. When the drive motor 351 stops rotating, under the action of the return torsion spring 232, the rotating plate slowly releases the paper tape, and the adjusting roller resets.

[0041] Based on the same inventive concept, embodiments of the present invention provide a control method for an automated sticker coating machine for vehicle rearview mirror glass lenses.

[0042] A control method for an automated sticker coating machine for vehicle rearview mirror glass lenses includes the following steps: Step S1: Acquire an image of the lens placement when the glass lens is placed on the conveyor belt 5.

[0043] A camera is fixedly installed on one side of the conveyor belt 5. The lens placement image refers to the image of the glass lens placed on the conveyor belt 5 obtained by taking a picture of the glass lens on the conveyor belt 5 through the camera, and the glass lens can be identified in the image.

[0044] Step S2: Determine the lens placement position based on the lens placement image and the preset reference point.

[0045] The reference point is a fixed position on the conveyor belt 5, and the distance between it and the camera is a fixed value.

[0046] The lens placement position refers to the actual position of the glass lens on the conveyor belt 5 when the glass lens is placed on the conveyor belt 5.

[0047] From the lens placement image, the shooting ratio of the image can be determined first by using the reference point. Then, based on the lens placement image, the relative position between the lens placement position and the reference point can be identified. Combining the shooting ratio of the image with the actual position of the reference point on the conveyor belt 5, the lens placement position can be determined.

[0048] Step S3: Based on the lens placement position, perform synchronous position calibration of the lens and the sticker laminating machine using a preset center calibration method, and determine whether there are any mirror impurity features based on the lens placement image recognition.

[0049] When the glass lens is placed on conveyor belt 5, its position needs to be corrected first so that the explosion-proof paper can be centered on the glass lens when it reaches the pressure plate 4. The system uses a center calibration method to simultaneously adjust the lens and the paper laminating machine. The center calibration method will not be described in detail here, but will be introduced in detail in subsequent embodiments.

[0050] Simultaneously, before applying the sticker to the glass lens, it is necessary to ensure that the surface of the glass lens is free of impurities to guarantee that the explosion-proof paper can adhere to the surface of the glass lens. Therefore, it is necessary to first identify the characteristics of mirror impurities from the lens placement image. Mirror impurity characteristics refer to impurities on the surface of the glass lens. The method for identifying mirror impurity characteristics will not be elaborated here, but will be described in detail in subsequent embodiments.

[0051] Step S4: When there are impurities on the lens, the preset cleaning mechanism 6 is controlled to clean the lens using a pre-applied paper strip, according to the preset lens cleaning method.

[0052] A cleaning mechanism 6 is provided on the adjustment base 1. The cleaning mechanism 6 is specifically used to clean the surface of the glass lens. When impurities are detected on the lens surface, the system controls the cleaning mechanism 6 to clean the glass lens surface using a lens cleaning method. The lens cleaning method will not be described in detail here, but will be described in detail in subsequent embodiments.

[0053] Step S5: After the preset transmission time, the sticker laminating machine is controlled to apply stickers to the glass lens through the pressure plate 4 using the preset sticker application method.

[0054] The conveying time is the time required for the glass lens to move from the cleaning mechanism 6 to the position of the pressing plate 4 along the conveyor belt 5, which will not be elaborated here.

[0055] After the glass lens surface is cleaned and moved to the pressure plate 4 position, the system will control the sticker laminating machine to apply stickers to the glass lens using a specific sticker application method. The sticker application method will not be described in detail here, but will be introduced in detail in subsequent embodiments.

[0056] The center calibration method includes the following steps: Step S30: The pusher plate 51 preset on the conveyor belt 5 is used to push the glass lens at the lens placement position by a preset initial alignment distance control, so as to align most of the glass lenses and acquire the corrective lens image after distance adjustment.

[0057] In this embodiment, a pusher plate 51 is horizontally slidable along the width direction on the conveyor belt 5, and a pusher cylinder connected to the pusher plate 51 is provided on one side of the conveyor plate. The pusher cylinder can drive the pusher plate 51 to move on the conveyor belt 5, thereby pushing the glass lens to adjust the position of the glass lens.

[0058] The pusher plate 51 cannot push the glass lens to the edge of the conveyor belt 5 because its movement is hindered when the glass lens is sandwiched between the edge of the conveyor belt 5 and the pusher plate 51. Therefore, the pusher plate 51 can only push the glass lens a short distance, making the distance between the pusher plate 51 and the edge of the conveyor belt 5 greater than the width of the glass lens. At this point, the pusher plate 51 may not be able to push all the glass lenses, but can only align most of them. Therefore, the initial alignment distance is the pushing distance of the pusher plate 51 when it pushes and aligns most of the glass lenses.

[0059] The corrective lens image refers to the image of the glass lens obtained by the camera re-capturing the glass lens after the glass lens is pushed by the push plate 51.

[0060] Step S300: Identify the position of the corrective lens from the corrective lens image.

[0061] The position of the corrective lens refers to the actual position of the glass lens on the conveyor belt 5 after it has been adjusted by the push plate 51. The method for determining the position of the corrective lens is the same as in step S2, and will not be repeated here.

[0062] Step S301: Determine the actual transport path of the lens based on the position of the corrective lens.

[0063] The actual transport path of the lens refers to the actual movement path of the glass lens on the conveyor belt 5. Different actual transport paths result in different center positions of the glass lens when it reaches the pressure plate 4. The distance between the glass lens and the edge of the conveyor belt 5 can be determined based on the position of the corrective lens, thus determining the actual transport path of the lens.

[0064] Step S302: Analyze whether the actual transport path of the lens is consistent with the preset alignment transport path.

[0065] The alignment conveying path refers to the movement path of most of the glass lenses that are aligned by the pusher plate 51. Since the initial alignment distance of the pusher plate 51 is a parameter preset by the technician, the alignment conveying path is also a parameter preset by the technician, which will not be elaborated here.

[0066] By comparing the actual transport path of the lens with the aligned transport path, it can be determined whether the glass lens has not been pushed by the pusher plate 51. If so, the horizontal position of the pressure plate 4 needs to be adjusted so that the glass lens and the pressure plate 4 can be aligned.

[0067] Step S303: When the actual transport path of the lens is inconsistent with the alignment transport path, calculate the path deviation between the actual transport path and the alignment transport path.

[0068] When the actual conveying path of the lens is consistent with the alignment conveying path, it means that the glass lens has been aligned by the push plate 51. When it is conveyed to the position of the pressure plate 4, it has been centered, so there is no need to adjust the position of the pressure plate 4.

[0069] When the actual transport path of the lens is inconsistent with the alignment transport path, the glass lens cannot be aligned at the position of the pressure plate 4, requiring adjustment of the pressure plate 4. The adjustment parameters of the pressure plate 4 need to be determined based on the path deviation between the actual transport path and the alignment transport path. The path deviation is the distance between the actual transport path and the alignment transport path. Once the actual transport path of the lens is determined, the path deviation can be determined.

[0070] Step S304: Adjust the base 1 to make horizontal fine adjustments to the pressure plate 4 according to the path deviation control.

[0071] After determining the path deviation, the horizontal adjustment component 12 in the base 1 is used to adjust the horizontal level of the pressure plate 4.

[0072] The method for identifying the characteristics of impurities on a mirror surface includes the following steps: Step S31: Determine the light source illumination position based on the lens placement position and the preset camera shooting position.

[0073] The camera's shooting position is the same as the camera's installation position.

[0074] In this embodiment, a light source is used to illuminate the glass lens, and the camera takes a picture of the glass lens from the reflection angle of the glass lens.

[0075] The position of the light source refers to the location of the light source that produces reflection on the glass lens when the camera takes a picture of it. According to the principle of light reflection, the angle of incidence equals the angle of reflection; therefore, once the camera's shooting position is determined, the position of the light source can also be determined. The light source position should be located along the straight line of the incident light ray.

[0076] Step S310: Illuminate the glass lens at the light source location and identify the reflective area of ​​the lens from the lens placement image.

[0077] The reflective area of ​​a lens refers to the area with the highest brightness in an image where the lens is placed; this area is the mirror surface of the glass lens. The brightness of the reflective area of ​​the lens is significantly different from the brightness of the surrounding environment. Based on this brightness characteristic, the reflective area of ​​the lens can be directly identified from the image where the lens is placed.

[0078] Step S311: Identify the color features of the area from the reflective area of ​​the lens.

[0079] When there are impurities on a glass lens, the impurities will block the path of light. At this time, the brightness of the position of the impurity in the mirror is low, and it will appear as a shadow.

[0080] Regional color features refer to all color characteristics within the reflective areas of a lens in an image. Regional color features can be directly identified from the reflective areas of a lens, and primarily include highlight color and shadow color.

[0081] Step S312: Determine whether the region color features include a preset shadow color.

[0082] By determining whether a region's color features contain shadow colors, it is possible to determine whether impurities are present.

[0083] Step S313: When a shadow color is present, a mirror impurity feature is defined. The mirror impurity feature is identified from the lens placement image to determine the adhesion distance and height of the impurity along the transmission direction.

[0084] Adhesion distance refers to the distance between the position of a specular impurity feature on the mirror surface and the edge of the mirror surface along the lens transport direction. Impurity height refers to the height characteristic of the specular impurity feature itself.

[0085] Once the characteristics of impurities on the mirror surface are identified, image recognition methods can be used to determine the adhesion distance and impurity height from the image of the lens placement.

[0086] Step S314: Output adhesion distance and impurity height.

[0087] The output adhesion distance and impurity height are used as parameters for subsequent cleaning of glass lenses with impurities.

[0088] Lens cleaning methods include the following steps: In this embodiment, the cleaning mechanism 6 includes a cleaning pressure plate 61 and a spray head 62. The cleaning pressure plate 61 is rotatably mounted on the adjusting base 1 and is located on the paper tape path of the paper receiving mechanism 3. The paper tape can pass over the cleaning pressure plate 61, which is driven to rotate by a motor. The cleaning pressure plate 61 is inclined downwards, and the position where the paper tape passes over the cleaning pressure plate 61 is close to the conveyor belt 5. When the glass lens passes under the cleaning pressure plate 61, the cleaning pressure plate 61 can press the paper tape onto the glass lens.

[0089] The spray head 62 is located on one side of the cleaning platen 61 and is used to spray the paper tape surface.

[0090] Since the explosion-proof paper has been attached to the glass lens at the pressure plate 4, when the paper tape is conveyed to the cleaning pressure plate 61, the surface of the paper tape is where the explosion-proof paper was originally attached. After the explosion-proof paper is removed, its surface is relatively smooth and clean, and can be used to clean impurities on the surface of the glass lens.

[0091] Step S40: Control the spray head 62 to spray a preset soap mist onto the surface of the paper tape that bypasses the cleaning pressure plate 61, and collect the lens update position in real time.

[0092] In this embodiment, when the paper tape is conveyed to the cleaning pressure plate 61, the spray head 62 sprays soapy water mist onto the surface of the paper tape. After the paper tape surface is covered with soapy water, the adsorption force is increased, thereby adsorbing and cleaning the impurities on the surface of the glass lens. In addition, the soapy water can stick to the surface of the glass lens, making it more comfortable to apply the explosion-proof paper to the glass lens later.

[0093] The lens update position refers to the real-time position of the glass lens as it moves on conveyor belt 5. The lens update position is determined by capturing images of the glass lens in real time and then identifying these images.

[0094] Step S41: When the lens update position coincides with the preset cleaning position, the cleaning plate 61 is pressed against the surface of the glass lens by a preset rotation angle, so that the cleaning plate 61 slides off the surface of the glass lens when the glass lens moves on the conveyor belt 5.

[0095] The cleaning position is the position where the cleaning pressure plate 61, set by the technicians, cleans the glass lens, which will not be described in detail here.

[0096] The rotation angle is set by the technicians at the angle at which the motor drives the cleaning plate 61 to rotate and press against the glass lens. This angle is mainly for glass lenses without obvious large impurities on the surface, and will not be elaborated here.

[0097] By determining whether the lens replacement position coincides with the cleaning position, it can be determined whether the glass lens has moved to the cleaning position. Once the glass lens has moved to the cleaning position, the motor controls the cleaning pressure plate 61 to rotate and press against the glass lens. As the glass lens moves, the paper tape can pick up and remove tiny impurities from the lens surface.

[0098] Step S42: When there are mirror impurities on the surface of the glass lens, determine the lifting time of the cleaning plate 61 based on the adhesion distance and the preset conveyor belt speed.

[0099] When there are no obvious large mirror impurities on the surface of the glass lens, the cleaning plate 61 is always pressed against the glass lens at a rotating angle to perform routine dust cleaning and apply soapy water to the entire surface of the glass lens.

[0100] When there are large mirror impurities on the surface of the glass lens, if the cleaning plate 61 is directly controlled by rotating the angle, the impurities will easily be pressed onto the surface of the glass lens, which will easily cause scratches on the lens surface. Therefore, the angle of the cleaning plate 61 needs to be corrected.

[0101] It takes a certain amount of time for the impurities on the lens surface to move to the contact position between the cleaning platen 61 and the lens surface; this time is called the lifting time. After the cleaning platen 61 contacts the glass lens and the lifting time has elapsed, the cleaning platen 61 needs to be lifted. The lifting time is the quotient of the adhesion distance and the conveyor belt speed.

[0102] Step S43: Match the correction angle of the cleaning pressure plate 61 according to the height of the impurities.

[0103] The correction angle is the adjustment angle when the cleaning pressure plate 61 rotates upward. The correction angle is directly proportional to the height of the impurities; the higher the height of the impurities, the larger the correction angle.

[0104] Step S44: When the glass lens comes into contact with the cleaning plate 61 and after the lifting time, the cleaning plate 61 is rotated by the correction angle control, and after the preset moving time, the cleaning plate 61 is reset by the rotation angle control.

[0105] Starting from the moment the glass lens comes into contact with the cleaning plate 61, after the lifting time, the impurity feature on the mirror surface moves to the point where the cleaning plate 61 comes into contact with the lens. At this time, the cleaning plate 61 is adjusted by the correction angle so that the cleaning plate 61 rotates upward, and the paper tape can contact the top surface of the impurity feature on the mirror surface and take away the impurity. During this process, the impurity will not cause wear to the lens.

[0106] The moving time is the time required for the cleaning platen 61, set by the technician, to remove the impurity features from the mirror surface.

[0107] After the movement time, the angle of the cleaning plate 61 is readjusted so that the angle of the cleaning plate 61 is a rotation angle, so that the cleaning plate 61 can abut against the surface of the glass lens again.

[0108] The sticker application method includes the following steps: Step S50: Acquire sensor detection signals in real time.

[0109] The sensor detection signal refers to the signal obtained by the sensor located below the pressure plate 4 when it detects the passing glass lens. The sensor is a photoelectric sensor, and the system can collect the sensor detection signal through the photoelectric sensor when the glass lens passes by.

[0110] Step S51: When the sensor detection signal is 1, a preset drive signal is output after a preset approach time.

[0111] When the sensor detection signal is 0, it means that no glass lens has passed by, and the sensor detection signal continues to be detected.

[0112] When the sensor detection signal is 1, it indicates that a glass lens has passed by, and the system detects a high-level sensor detection signal. When the sensor detection signal appears, preparations need to be made to apply the sticker to the glass lens.

[0113] The approach time is the time set by the technician, which is the time interval between when the glass lens is detected and identified by the sensor and when the pressure plate 4 comes into contact with the end of the glass lens. It will not be elaborated here.

[0114] The drive signal is a signal set by the technician and is used to drive the drive motor 351 to run.

[0115] Step S52: Match the motor drive angle according to the preset lens diameter.

[0116] The motor drive angle refers to the angle at which the motor rotates 351 degrees each time a sticker is applied.

[0117] In order to better apply the paper to the surface of the glass lens, the length of the paper tape moving at the four points of the pressure plate is related to the diameter of the lens, and the motor drive angle is related to the length of the paper tape moving at the four points of the pressure plate. Therefore, the motor drive angle is directly proportional to the diameter of the lens; the larger the diameter of the lens, the larger the motor drive angle.

[0118] Step S53: Match the motor drive speed according to the preset conveyor belt speed.

[0119] Motor drive speed refers to the speed at which the motor rotates each time the sticker is applied. In order for the explosion-proof paper to adhere better to the surface of the glass lens, the paper tape's movement speed needs to match the glass lens's movement speed. Therefore, the motor drive speed is directly proportional to the conveyor belt's conveying speed; the higher the conveyor belt's conveying speed, the higher the motor drive speed.

[0120] Step S54: Start the drive motor 351 with the drive signal, and control the drive motor 351 to rotate with the motor drive angle and motor drive speed to stick the explosion-proof paper on the surface of the glass lens, and collect the image of the sticker on the glass lens.

[0121] In determining the control parameters of the drive motor 351, the drive motor 351 is started by controlling the drive signal, and then the drive motor 351 is rotated to pull the paper tape to stick the explosion-proof paper onto the glass lens.

[0122] The glass lens sticker image refers to an image captured by a camera mounted on conveyor belt 5 after the sticker application process. Both the glass lens and the explosion-proof paper on it can be identified from the glass lens sticker image.

[0123] Step S55: Determine whether the glass lens has been properly stickered based on the glass lens sticker image.

[0124] By identifying the features of the explosion-proof paper from the image of the glass lens sticker, it can be determined whether the explosion-proof paper is correctly affixed to the surface of the glass lens after the pressure plate 4 sticker is applied.

[0125] Step S56: When the glass lens is coated, the height of the roller is set according to the preset lens thickness.

[0126] In this embodiment, a roller 7 is vertically mounted on one side of the pressure plate 4, and the height distance between the roller 7 and the conveyor belt 5 can be adjusted by a motor. The roller setting height refers to the height of the roller 7 on the conveyor belt 5. The roller setting height is consistent with the lens thickness.

[0127] Step S560: Adjust the preset roller 7 to the roller roller setting height so that the roller 7 is pressed onto the surface of the glass lens after the sticker is applied and the explosion-proof paper is smoothed out.

[0128] Once the glass lens is confirmed to be properly pasted from the image, the glass lens moves along the conveyor belt 5 and passes between the roller 7 and the conveyor belt 5. At this time, the roller 7 is raised and lowered according to the height setting of the roller so that the roller 7 presses on the glass lens and can roll off the glass lens to smooth the explosion-proof paper on the surface of the glass lens.

[0129] The steps to handle incomplete sticker application on glass lenses are as follows: In this embodiment, when the explosion-proof paper on the pressure plate 4 fails to adhere correctly to the glass lens surface and is missed, in order to avoid wasting the explosion-proof paper, it is affixed to the second cleaned glass lens using the cleaning block located at the rear. Simultaneously, the first glass lens that was not correctly affixed is re-affixed. That is, the cleaning block can be used both to clean impurities from the glass lens surface and to affix paper to the glass lens surface. Here, the first glass lens is the one that was not correctly affixed, and the second glass lens is either in a state of pending completion or has just been cleaned.

[0130] Step S57: Match the spacing between the glass lens to be stickered and the glass lens to be cleaned according to the paper tape length between the preset pressure plate 4 and the preset cleaning pressure plate 61.

[0131] To ensure that the two glass lenses are pasted on synchronously, the spacing between them needs to be adjusted. This spacing is determined by the length of the paper strip between the pressure plate 4 and the cleaning plate 61; that is, when the explosion-proof paper moves from the position of the pressure plate 4 to the position of the cleaning plate 61, the second glass lens should be positioned exactly at the cleaning plate 61. The spacing is consistent with the length of the paper strip between the pressure plate 4 and the cleaning plate 61.

[0132] Step S570: Control the preset lever to move the glass lens to be cleaned according to the interval distance.

[0133] In this embodiment, a lever is provided on one side of the conveyor belt 5. The lever can be used to horizontally move the glass lens, thereby adjusting the distance between the two glass lenses. Here, the distance between the front and rear glass lenses is controlled by moving the lever.

[0134] Step S571: After cleaning the glass lens to be cleaned, match the overall moving distance according to the lens diameter.

[0135] Before applying the sticker, the surface of the second glass lens needs to be cleaned. Therefore, the second glass lens needs to be cleaned first.

[0136] In this embodiment, the sticker laminating machine is mounted on the displacement mechanism 8, which can drive the sticker laminating machine to move horizontally.

[0137] The total moving distance is the distance the sticker laminating machine moves horizontally on the displacement mechanism 8. The total moving distance is consistent with the lens diameter, so that the glass lens that has passed under the pressing plate 4 can return to under the pressing plate 4 and be ready to be re-applied.

[0138] Step S572: Control the preset displacement mechanism 8 to move the sticker laminating machine as a whole by controlling the overall movement distance, and re-control the pressing plate 4 to apply the sticker to the glass lens to be stickered, and simultaneously control the cleaning plate 61 to apply the missed explosion-proof paper to the cleaned glass lens.

[0139] After the sticker laminating machine is repositioned, the first glass lens can return to below the pressure plate 4, while the second cleaned glass lens can return to below the cleaning pressure block. At this time, the control conveyor belt 5 moves again and the control drive motor 351 starts. The pressure plate 4 can apply new explosion-proof paper to the first glass lens, while the cleaning pressure block can apply old explosion-proof paper to the second glass lens.

[0140] Step S573: After the stickers are applied to both glass lenses, control the sticker laminating machine to reset.

[0141] After both glass lenses have been coated, the coating machine is reset and then applied to the new glass lens.
