Description

Technical Field

[0001] This invention relates to the field of liquid crystal display alignment film printing technology. More specifically, this invention relates to a resin plate inspection system with black and white backlight and multiple light sources, and its method of use. Background Technology

[0002] With the advancement of technology and the abundance of material life, the LCD panel industry is developing rapidly, and flexible printing technology is widely used. This printing technology utilizes flexible resin plates. Currently, the mainstream resin plate manufacturing processes in the industry are quite similar, including original plate production, laser engraving or UV exposure etching, pre-shipment cleaning, cutting and drilling, pre-shipment inspection, and packaging. Regardless of how the pattern on the resin plate is processed, numerous processes and a final plate inspection are indispensable. During the resin plate manufacturing process, some material defects, as well as resin defects, damage, and foreign objects caused by human error or equipment, are inevitable. All of these need to be screened and marked for shipment during the final plate inspection stage. Currently, the conventional plate inspection method involves placing a black pad on the bottom of the resin plate and inspecting the surface with a green or white light. However, the pad for the G8.6 generation line is larger, making the pad placement more difficult, and the handheld green or white light source has a smaller coverage area, making prolonged handheld operation tiring for personnel. Ultimately, all of the above will affect the efficiency and results of pre-shipment inspection. Defective versions shipped to customers will not only damage the reputation of the products themselves, but in severe cases, may also cause a batch of printing defects and quality accidents for customers. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

A second transmission motor is also provided on the transverse guide rail, and the output end of the second transmission motor is connected to the second transmission wheel to drive the second transmission wheel to rotate, thereby driving the transverse transmission belt to move laterally. The fixed end of the universal adjustment base is connected to the transverse transmission belt, and the universal adjustment base is driven to move laterally through the transverse transmission belt.

[0008] Preferably, a supporting main frame is fixed inside the darkroom, the supporting main frame is located outside the inspection platform, and the longitudinal guide rail is fixedly connected to the top of the supporting main frame at the corresponding position.

[0009] Preferably, fluorescent tubes for lighting and FFU (Fan Filter Unit) are also connected and installed on the main supporting frame.

[0010] Preferably, it also includes a marking and verification unit, which includes a frame plate, a movement control terminal, and an analysis and display terminal. The side of the frame plate is fixedly connected to the top of the supporting main frame and is located above the transmission mechanism. The frame plate has cell holes arranged in an array, and all cell holes cover the area where the resin plate is located in the horizontal direction. A focused light source is also provided above each cell hole. The color of the focused light source is different from the background color of the first high-intensity light source, the second high-intensity light source, and the electronic backlight. The focused light source can emit a point beam vertically downward to the corresponding position of the resin plate. The movement control terminal is arranged on the handle electronic control unit. The mobile control terminal includes a touch screen, a control chip, and a data transmission module. The control chip is communicatively connected to the spotlight source and electrically connected to the touch screen. The spotlight source is switched on and off via the touch screen. The analysis and display terminal includes a central processing unit (CPU) and a display and storage module electrically connected to the CPU. The data transmission module is used to record and transmit the switching status of all spotlight sources to the CPU and storage module. The CPU is used to analyze the switching status of the spotlight source corresponding to each resin plate and display it on the display. It is also used to analyze the position corresponding to the on / off state of the spotlight source to find defect points or predict future occurrence points of the resin plate.

[0011] On the other hand, the present invention also provides a method of using a resin plate inspection system with black and white backlight and multiple light sources, comprising the following steps: S1. Install the electronic backlight panel on the base, and lay the resin plate flat on the electronic backlight panel; S2. Adjust the light source of the electronic backlight panel to white background through the handle electronic control unit, set the color of the first strong light source to white light, set the color of the second strong light source to green light, and adjust the first strong light source to the on state. S3. The transmission mechanism is controlled by the handle electronic control unit to move the first high-intensity light source and adjust the light source angle to cooperate in inspecting resin bubble defects in the entire inspection area of ​​the resin plate. S4. Adjust the light source of the electronic backlight panel to a black background through the handle electronic control unit, adjust the second high-intensity light source to the on state, and control the transmission mechanism through the handle electronic control unit to drive the second high-intensity light source to move and adjust the light source angle, so as to carry out the resin damage and environmental foreign matter inspection work in the resin plate full-surface inspection area.

A2. When the first strong light source or the second strong light source moves to inspect and finds a suspected defect or confirms a defect, the top of the corresponding position of the focusing light source is turned on by operating the touch screen. The focusing light source forms a bright spot on the resin plate directly below, and the corresponding open mark is displayed on the display. A3. Continue to inspect the resin plate. After all areas of a single resin plate have been inspected, generate a map of suspected or confirmed defect distribution points of the resin plate. Review the locations where the spotlight source has been turned on to determine whether they are confirmed as defects. A4. Analyze the suspected defect distribution point map or confirmed defect distribution point map of a batch of resin plates, perform overlay analysis, and analyze the possibility of problems in the resin plate production process for multiple or densely distributed defect points in a certain area.

On the inspection platform, an adjustable color electronic backlight panel, a glass platform and a resin plate are arranged in sequence. The transmission mechanism is controlled by the handle electronic control unit, which drives the inspection lamp source to move to the required position above the resin plate. This not only solves the problem of operators having to hold the lamp source to inspect the resin plate before shipment, which is laborious, but also eliminates the risk of damaging the resin plate caused by laying a black pad on the inspection platform. The light source position movement and light source angle adjustment functions save inspection time and improve defect inspection capabilities, thereby improving inspection efficiency. The system also includes a marking and verification unit and corresponding operation methods, which improves production capacity while ensuring product shipment quality.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0017] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] like Figure 1 As shown, firstly, the present invention provides a resin plate inspection system with black and white backlight and multiple light sources, comprising: The inspection platform includes a base 2, which is fixed to the floor of the dark room. An adjustable backlight panel 3 is installed on the top of the base 2. A glass platform is installed on the top of the backlight panel 3. A resin plate 11 is laid on the glass platform. The transmission mechanism includes a longitudinal transmission device 4 and a transverse transmission device 6. The longitudinal transmission device 4 is fixed above the inspection platform along the width direction of the inspection platform. The transverse transmission device 6 is arranged along the length direction of the inspection platform and is slidably connected to the bottom of the longitudinal transmission device 4. The bottom of the transverse transmission device 6 is connected to a universal adjustment base 72. The light source is inspected, which includes a first high-intensity light source 8 and a second high-intensity light source 9 respectively connected to the bottom of a universal adjustment base 72. The first high-intensity light source 8 is used to irradiate the resin plate 11 to inspect for resin bubbles, and the second high-intensity light source 9 is used to irradiate the resin plate 11 to inspect for resin damage and environmental foreign matter. The handle control unit 10 is communicatively connected to the first high-intensity light source 8, the second high-intensity light source 9, the horizontal transmission device 6, the vertical transmission device 4, and the universal adjustment base 72, respectively, to control the vertical transmission device 4 to drive the horizontal transmission device 6 to move parallel to the width direction of the inspection platform, to control the horizontal transmission device 6 to drive the universal adjustment base 72 to move along the length direction of the inspection platform, to control the universal adjustment base 72 to rotate freely, and to control the light intensity of the first high-intensity light source 8 and the second high-intensity light source 9 respectively.

[0019] The longitudinal transmission device 4 is used to drive the transverse transmission device 6 to move longitudinally (i.e., in the width direction of the resin plate 11 on the inspection platform). The transverse transmission device 6 is used to drive the universal adjustment base 72 to move laterally (i.e., in the length direction of the resin plate 11 on the inspection platform). The universal adjustment base 72 can rotate freely 360°. All devices are powered on. The substrate of the inspection platform is glass. The electronic backlight panel 3 can be adjusted to black or white. The handle control unit is handheld. During the operation of inspecting the resin plate 11, the personnel can control the switching of the electronic backlight panel 3, the switching of different colored inspection light sources, and the movement and light angle adjustment of the inspection light source in any direction. The inspection light source can be moved or stopped at any position in the inspection area. Common defects of the resin plate 11 include resin bubbles, resin damage, and environmental foreign objects. Resin bubbles are transparent and require a white light with a white backlight panel for light transmission inspection. Resin damage and environmental foreign objects require a green light with a black backlight panel for higher visibility inspection.

[0020] The resin plate 11 inspection system of the present invention with black and white backlight and multiple light sources not only solves the problem of laborious operation of operators holding light sources to inspect resin plates 11 before shipment, but also saves inspection time and improves inspection capabilities through the light source position movement and light source angle adjustment functions. It also solves the risk of damaging the resin plate 11 caused by laying black pads on the inspection platform, thereby improving inspection efficiency and defect inspection capabilities, increasing production capacity while ensuring product shipment quality.

[0021] In another technical solution, such as Figure 1-3As shown, the longitudinal transmission device 4 includes a pair of longitudinal guide rails. The longitudinal guide rails extend along the width direction of the darkroom and are arranged above both ends of the inspection platform. A longitudinal transmission belt is sleeved on the longitudinal guide rails. A first transmission wheel is connected to the inner side of the longitudinal transmission belt. A first transmission motor 5 is also provided on the longitudinal guide rails. The output end of the first transmission motor 5 is connected to the first transmission wheel to drive the first transmission wheel to rotate, thereby driving the longitudinal transmission belt to move longitudinally. The two ends of the transverse transmission device 6 are respectively connected to the longitudinal transmission belt on the corresponding side. The transverse transmission device 6 is driven to move longitudinally by the longitudinal transmission belt, which can realize the stable movement of the transverse transmission device 6, effectively ensure the accuracy and reliability of the translation process, improve the operating efficiency of the equipment inside the darkroom, enhance the overall work efficiency, and reduce the labor intensity and difficulty of manual operation.

[0022] In another technical solution, such as Figure 1-3 As shown, the transverse transmission device 6 includes a transverse guide rail, with both ends of the transverse guide rail connected to the corresponding longitudinal transmission belts. A transverse transmission belt is fitted onto the transverse guide rail, and a second transmission wheel is connected to the inner side of the transverse transmission belt. A second transmission motor is also installed on the transverse guide rail, and the output end of the second transmission motor is connected to the second transmission wheel to drive the second transmission wheel to rotate, thereby driving the transverse transmission belt to move laterally. The fixed end of the universal adjustment base 72 is connected to the transverse transmission belt. The universal adjustment base 72 is driven to move laterally by the transverse transmission belt. In conjunction with the longitudinal translation of the longitudinal transmission device 4, the light source can cover any area of ​​the inspection platform, eliminating the need for operators to hold and move the light source for inspection. This ensures the stability of the light source movement and allows for precise control of the light source position, further reducing the labor intensity of manual operation, improving the accuracy of defect inspection, and making the inspection process smoother and more efficient.

[0023] In another technical solution, such as Figure 1-3 As shown, a supporting main frame 1 is fixed inside the darkroom. The supporting main frame 1 is located outside the inspection platform. The longitudinal guide rail is fixedly connected to the top of the supporting main frame 1 at the corresponding position. The supporting main frame 1 of the darkroom is similar to the design of a clean booth. The selected profiles are all high-strength aluminum profiles, which have a certain load-bearing capacity, allowing the longitudinal transmission device 4 to be stably erected above the inspection platform. It will not obstruct or interfere with the operation of placing the resin plate 11 on the inspection platform. At the same time, relying on the overall support of the supporting main frame 1, the structural stability during the transverse and longitudinal transmission process can also be improved, avoiding the displacement of the light source position caused by the shaking of the transmission components, and further ensuring the accuracy of the defect inspection position positioning.

[0024] In another technical solution, such as Figure 1-3 As shown, fluorescent tubes for lighting and FFU fan filter units are also connected and installed on the main supporting frame 1.

[0025] Fluorescent tubes provide ample operating lighting for operators, facilitating basic operations such as picking up, placing, and positioning resin plates 11 in the darkroom without the need for additional external operating light sources. The FFU fan filter unit continuously circulates and filters the air in the darkroom, removing airborne dust and debris to prevent dust from settling on the surface of the resin plate 11 to be inspected, thus avoiding obscuring existing defects or misidentifying dust as defects. This further improves the accuracy of defect inspection results and maintains the cleanliness of the darkroom, reducing contamination of the resin plate 11 during storage and inspection.

[0026] In another technical solution, such as Figure 1-3 As shown, it also includes a marking and verification unit, which includes a frame plate 12, a movement control terminal, and an analysis and display terminal. The side of the frame plate 12 is fixedly connected to the top of the supporting main frame 1 and is located above the transmission mechanism. The frame plate 12 has cell holes arranged in an array, and all cell holes cover the area where the resin plate 11 is located in the horizontal direction. A focused light source 13 is also provided on the upper side of each cell hole. The color of the focused light source 13 is different from the background color of the first strong light source 8, the second strong light source 9, and the electronic backlight 3. The focused light source 13 can emit a point beam vertically downward to the corresponding position of the resin plate 11. The movement control terminal is arranged in the handle electronic control unit 1. On the 0, the mobile control terminal includes a touch screen, a control chip, and a data transmission module. The control chip is communicatively connected to the focusing light source 13 and electrically connected to the touch screen. The control chip operates the switching of the focusing light source 13 through the touch screen. The analysis display terminal includes a central processing unit and a display and a storage module electrically connected to the central processing unit. The data transmission module is used to record and transmit the switching of all focusing light sources 13 to the central processing unit and the storage module. The central processing unit is used to analyze the switching status of the focusing light source 13 corresponding to each resin plate 11 and display it on the display. It is also used to analyze the position corresponding to the on state of the focusing light source 13 to find defect points or predict the future occurrence points of the resin plate 11.

[0027] Prepare the spotlight source 13 and the frame plate 12, then turn on the first high-intensity light source 8 and the second high-intensity light source 9 for inspection. When a suspected defect or a confirmed defect is found, turn on the upper spotlight source 13 to emit a dot beam downwards (the area of ​​the dot beam is set according to the size of the inspection block) to mark the defect location. Then continue to move the first high-intensity light source 8 or the second high-intensity light source 9 to inspect the remaining area of ​​the resin plate 11. Repeat the operation until all areas of the resin plate 11 have been inspected. Simultaneously, summarize and display the marked points on the monitor to facilitate verification and inspection, reduce errors or omissions in manual inspection operations, and improve the accuracy of the resin plate 11 inspection. When multiple resin plates 11 repeatedly show suspected defect points in similar or the same locations, analyze whether there is a problem in the resin plate 11 production process that caused the defect.

[0028] This invention also provides a method of using a resin plate 11 inspection system with black and white backlight and multiple light sources, combined with Figure 1-3 As shown, it includes the following steps: S1. Install the electronic backlight panel 3 on the base 2, and lay the resin plate 11 flat on the electronic backlight panel 3; S2. Adjust the light source of the electronic backlight panel 3 to white background through the handle electronic control unit 10, set the color of the first strong light source 8 to white light, set the color of the second strong light source 9 to green light, and adjust the first strong light source 8 to the on state. S3. The transmission mechanism is controlled by the handle control unit 10 to move the first high-intensity light source 8 and adjust the light source angle to cooperate in inspecting the resin bubble defects in the entire inspection area of ​​the resin plate 11. S4. Adjust the light source of the electronic backlight panel 3 to a black background through the handle electronic control unit 10, adjust the second strong light source 9 to the on state, and control the transmission mechanism through the handle electronic control unit 10 to drive the second strong light source 9 to move and adjust the light source angle, so as to carry out the resin damage and environmental foreign matter inspection work in the entire inspection area of ​​the resin plate 11.

[0029] By setting up an electronic backlight panel 3 and using a transmission mechanism to move a strong light source, manpower is greatly saved in the pre-shipment inspection process of resin plate 11, and inspection efficiency and defect inspection capabilities are also greatly improved.

[0030] In another technical solution, such as Figure 1-3 As shown, the inspection of resin plate 11 is recorded, analyzed, and predicted using the marking verification unit, specifically including the following steps: A1. Before controlling the transmission mechanism to move the first high-intensity light source 8, install and align the frame plate 12 and the spotlight source 13 above the transmission mechanism, covering all areas in the plane of the corresponding resin plate 11, and display the dot matrix pattern of the frame plate 12 and the spotlight source 13 on the display.

[0031] A2. When the first strong light source or the second strong light source moves to inspect and finds a suspected defect or confirms a defect, the spotlight 13 at the top of the corresponding position is turned on by operating the touch screen. The spotlight 13 forms a bright spot on the resin plate 11 directly below it, and at the same time, the corresponding open mark is displayed on the display.

[0032] A3. Continue to inspect the remaining areas of resin plate 11 in sequence. After all areas of a single resin plate 11 have been inspected, generate a distribution map of suspected defects or a distribution map of confirmed defects for resin plate 11. Review the locations where the spotlight 13 has been turned on to determine whether they are confirmed as defects. If not, turn off the spotlight 13 at the corresponding location. If the review confirms that it is a defect, retain the spotlight 13 at the corresponding location to facilitate quick location of the defect for subsequent processing.

[0033] A4. Analyze the suspected defect distribution point map or confirmed defect distribution point map of a batch of resin plates 11, perform overlay analysis, analyze the possibility of problems in the resin plate 11 production process for multiple or dense defect distribution points in a certain area, so as to make the production and quality inspection of resin plates 11 more systematic and predictable, and pay attention to the maintenance or upkeep of related equipment in advance.

[0034] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.

When the first strong light source or the second strong light source moves to inspect and finds a suspected defect or confirms a defect, the top of the corresponding position of the focusing light source is turned on by operating the touch screen. The focusing light source forms a bright spot on the resin plate directly below, and the corresponding open mark is displayed on the display. A3. Continue to inspect the resin plate. After all areas of a single resin plate have been inspected, generate a map of suspected or confirmed defect distribution points of the resin plate. Review the locations where the spotlight source was turned on to determine whether they are confirmed as defects. A4. Analyze the suspected defect distribution point map or confirmed defect distribution point map of a batch of resin plates, perform overlay analysis, and analyze the possibility of problems in the resin plate production process for multiple or densely distributed defect points in a certain area.
