Description

Technical Field

[0001] This invention relates to the field of display screen inspection technology, specifically to an automatic display screen inspection device for online defect marking. Background Technology

[0002] As we all know, with the development of display panels towards high definition, flexibility and large size, manual visual inspection is no longer able to meet the high-precision and high-efficiency mass production requirements. Automatic optical inspection technology based on machine vision and image processing has become the industry mainstream. It integrates precision optical imaging, intelligent algorithms and automatic control, and can identify and mark defects such as bright spots, dark spots, mura and scratches online in real time, supporting the quality control and intelligent upgrading of production lines.

[0003] A search revealed a Chinese patent for a fully automatic display screen inspection machine, application publication number CN106353334B. This patent includes a cabinet, a translation device for transporting display screens within the cabinet, a positioning device for positioning the display screens on the translation device, a power-on device for powering on the positioned display screens, and an inspection device for photographing and inspecting the display screens. The inspection device is located above the translation device. This fully automatic display screen inspection machine enables automatic product transport via the translation device, automatic product positioning and fixing via the positioning device, automatic power-on and signal transmission via the power-on device, and automatic inspection and recording of the product after power-on and image display. This fully automatic display screen inspection machine can detect defects such as damage, insufficient brightness, and unclear display on display screens, offering high inspection efficiency and a high degree of automation, saving time and manpower, and fully meeting the needs of automated production.

[0004] When testing monitors of different specifications, the monitor is fixed to the testing equipment and subjected to various environmental simulations, including extreme shaking until defects are generated. The defects are then marked before further testing. The problems with existing technologies are: the existing fixing structures can only fix monitors of a single specification, lacking structures adaptable to different specifications. This reduces the flexibility in fixing monitors of different specifications. Furthermore, existing environmental simulation equipment can only simulate the entire environment in which the monitor is located, lacking structures for simulating different degrees of environmental conditions in specific areas of the monitor. This reduces the flexibility in detecting defects of varying degrees caused by complex and changing environmental simulations, and also prevents the marking of defects at corresponding locations. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an online defect marking automatic detection device for displays. It features a fixing structure adaptable to different display sizes, thus improving flexibility in fixing displays of varying specifications. It also has a structure that simulates different degrees of environment for localized areas of the display, enhancing the flexibility of detecting defects of varying degrees arising from complex and changing environmental simulations. Furthermore, it allows for the marking of defects at corresponding locations.

[0006] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic detection device for online defect marking display screens, comprising a fixing mechanism and a testing mechanism, wherein the testing mechanism is located at the rear of the fixing mechanism, and a robotic arm is mounted at the front of the fixing mechanism; the fixing mechanism includes a support component, an adaptation component, a transmission component, an adjustment component, and a positioning component; the adaptation component is located at the front of the support component, the transmission component is located on the surface of the adaptation component, the adjustment component is located at the output end of the transmission component, and the positioning component is located inside the adjustment component; the testing mechanism includes a detection component, a clamping component, a humidification component, and a heating component; the detection component is located on the side of the positioning component away from the transmission component, the clamping component is located at the bottom of the detection component, the humidification component is located on the surface of the detection component, the heating component is located on the surface of the detection component, and the output end of the robotic arm is bolted to the rear of the support component.

[0007] By adopting the above technical solution, a fixing mechanism and a testing mechanism are set up. The fixing mechanism is a structure that provides a limit to the testing mechanism and can drive the testing mechanism to adapt to the shape of the current display. It can also position the testing mechanism in local areas of the display where multiple defects need to be detected. At the same time, it can cooperate with a robotic arm, which can drive the fixing mechanism to simulate the movement of the testing mechanism and the display together, simulating a scene of violent shaking. The testing mechanism is a structure that performs visual inspection and marking of local areas of the display. It can also heat and humidify the area while detecting defects, simulating the environment of humidity and temperature changes.

[0008] The present invention is further configured such that: the support assembly includes a support plate, a support frame and an arc-shaped frame, the rear side of the support plate is bolted to the output end of the robotic arm, four support frames are bolted to the four corners of the support plate respectively, and four arc-shaped frames are bolted to the top, bottom and sides of the support frame respectively.

[0009] By adopting the above technical solution, a support component is set up. The support plate, support frame, and arc frame form a structure that supports the adaptation component. As the robotic arm swings and shakes, the adaptation component will swing and shake the entire fixed mechanism and the entire testing mechanism, thus simulating the motion environment. The support plate uses the output end of the robotic arm as a support point and can move synchronously with the displacement of the robotic arm. The support frame can use the four corners of the support plate as support points to provide stable support for the arc frame. The arc frame can guide and limit the displacement of the adaptation component with an arc path, avoiding excessive displacement that would prevent it from effectively adapting to the shape of the current display.

[0010] The invention is further configured such that: the adaptation component includes an adaptation electric cylinder, a sliding sleeve, and a sliding plate; eight adaptation electric cylinders are respectively rotatably connected to the top, bottom, and both sides of the front side of the support plate; the sliding sleeve is slidably connected to the output end of the adaptation electric cylinder; the sliding plate is bolted to the rear side of the sliding sleeve; and the surface of the sliding plate is slidably connected to the inner side of the arc-shaped frame.

[0011] By adopting the above technical solution, by setting an adaptation component, the adaptation electric cylinder, the sliding sleeve, and the sliding plate form a structure that guides the transmission component. It can move along the arc frame, thereby guiding the position of the transmission component and displacing it to the position required by the display. By driving the transmission component with the adaptation electric cylinder, the transmission component can be centered on the display and adapt to the shape of the display. The sliding plate moves along the arc frame with the sliding sleeve on the adaptation electric cylinder, which further increases the stability of the adaptation electric cylinder when limiting the display under the limitation of the sliding sleeve and the sliding plate.

[0012] The invention is further configured such that: the transmission assembly includes a fixed angle plate, an electric winch, a non-powered winch, and gears; the fixed angle plate is bolted to the output end of the electric cylinder; the electric winch is bolted to the bottom of the rear side of the fixed angle plate; the non-powered winch is bolted to the top of the rear side of the fixed angle plate; and two gears are bolted to the surfaces of the output shafts of the electric winch and the non-powered winch, respectively, and the gears mesh with each other.

[0013] By adopting the above technical solution, a transmission component is set up. The fixed angle plate, electric winch, non-powered winch, and gear form a transmission structure for the adjustment component. The length of the adjustment component can be changed, thereby adjusting the bending degree of the positioning component. This allows the testing mechanism to clamp and fix the display. The fixed angle plate provides a limit for the electric winch and non-powered winch. When the electric winch is operating, it drives the gear to rotate the gear on the non-powered winch in the opposite direction. Thus, when the electric winch rotates in the forward direction, the gear rotates the non-powered winch in the reverse direction. This allows the electric winch and non-powered winch to maintain the same speed when winding and unwinding the adjustment component.

[0014] The present invention is further configured such that: the adjusting component includes a guide wheel, a bending wire, and a stretching wire; the bending wire is installed at the output end of an electric winch, the stretching wire is installed at the output end of a non-powered winch, and the guide wheel is located on the opposite side of the bending wire and the stretching wire.

[0015] By adopting the above technical solution, by setting an adjustment component, the guide wheel, the bending line, and the extension line form a structure for adjusting the bending degree of the positioning component. The bending degree of the positioning component can be adjusted, so that it can drive the testing mechanism to move towards the display and adapt to the shape of the display. By guiding the bending line and the extension line through the guide wheel, when the bending line is wound and released by the electric winch, the unpowered winch can synchronously wind and release the extension line in the opposite direction. When the bending line shortens, the extension line will lengthen, and the positioning component will make a bending action. Conversely, the positioning component will make a straightening action.

[0016] The present invention is further configured such that: the positioning assembly includes a positioning rod, an adjusting electric cylinder, and a limiting plate; the positioning rod is bolted to the rear side of the fixed angle plate; the adjusting electric cylinder is rotatably connected to the rear side of the positioning rod; the limiting plate is bolted to the output end of the adjusting electric cylinder; the top and bottom of the positioning rod are bolted to the side opposite to the guide wheel; the bottom of the front side of the limiting plate is connected to a bending bolt; and the top of the front side of the limiting plate is connected to a stretching bolt.

[0017] By adopting the above technical solution, the positioning component, the positioning rod, the adjusting electric cylinder, and the limiting plate can form a structure that limits the testing mechanism. It can also adapt to the errors caused by the elongation and shortening of the bending and stretching wires, and further drive the testing mechanism to adapt to the shape of the display. Through the bendable limiting structure formed by the positioning rod and the adjusting electric cylinder, the limiting plate can drive the adjusting electric cylinder to rotate along the positioning rod as the bending and stretching wires elongate and stretch, thereby achieving the effect of driving the testing mechanism to move synchronously and adapt to the shape of the current display.

[0018] The invention is further configured such that: the detection component includes a positioning seat, a positioning spring rod, a limiting frame, and an industrial camera; the positioning seat is bolted to the rear side of the limiting plate; the positioning spring rod is bolted to the inner side of the positioning seat; the limiting frame is rotatably connected to the surface of the positioning seat; the inner side of the limiting frame is rotatably connected to the side of the positioning spring rod away from the positioning seat; the industrial camera is bolted to the surface of the limiting frame; and the spring end of the positioning spring rod is bolted to the inner side of the positioning seat and the inner side of the limiting frame, respectively.

[0019] Using the above technical solution, by setting up detection components, the positioning seat, positioning spring rod, limiting frame, and industrial camera can form a structure for limiting the clamping components. As the limiting plate moves, the entire testing mechanism can be moved synchronously to the structure required to fix the display. With the limiting plate as the support point, the positioning seat can provide limiting for the positioning spring rod and the limiting frame. The positioning spring rod applies elastic force to the limiting frame through its own elasticity, so that the limiting frame always remains reset through elasticity when rotating to adapt to the shape of the display, thereby stably clamping the display. The industrial camera can perform visual inspection on the clamping point of the clamping components and mark defects at that location through its own visual inspection.

[0020] The present invention is further configured such that: the clamping assembly includes a reset spring rod, a rotating block, and a soft sleeve rod; the reset spring rod is bolted to the bottom of the positioning seat; the rotating block is rotatably connected to the surface of the reset spring rod; the spring end of the reset spring rod is bolted to the front and rear sides of the inner side of the rotating block; and the soft sleeve rod is bolted to both sides of the bottom of the rotating block.

[0021] By adopting the above technical solution, a clamping assembly is set up. The reset spring rod, rotating block, and soft sleeve rod form a structure for clamping the monitor. The monitor's exterior can be clamped. The reset spring rod limits the rotating block with the limiting frame as the support point. The rotating block, which consists of two rotating structures, can maintain mutual reset elasticity under the elastic force of the limiting ends of the reset spring rod. This can drive the soft sleeve rod connected to it to move towards the monitor, generating a clamping force to hold the monitor, and ultimately achieving the effect of fixing the monitor.

[0022] The present invention is further configured such that: the humidification assembly includes a pressure pump, a water valve, and an atomizing nozzle; the pressure pump is bolted to the side of the limiting frame away from the flexible sleeve rod; the water valve is connected to the input end of the pressure pump; the atomizing nozzle is connected to the output end of the pressure pump; and the output end of the atomizing nozzle is close to the flexible sleeve rod.

[0023] By adopting the above technical solution, a humidification component can be set up. The pressurizing pump, water valve and atomizing nozzle can form a structure for humidifying the display. By humidifying the environment around the display, the effect of simulating the humidity environment can be achieved. By connecting the water valve to an external water supply device, the pressurizing pump can draw water in and pressurize it before sending it to the atomizing nozzle. After being atomized by the atomizing nozzle, the water is sprayed onto the display and its surroundings to simulate a local humidity environment.

[0024] The present invention is further configured such that: the heating assembly includes a guide pipe, an electric heating grid, and an exhaust fan; the guide pipe is bolted to the side of the limiting frame away from the atomizing nozzle; the electric heating grid is bolted to the output end of the guide pipe; the exhaust fan is bolted to the inner side of the guide pipe; and the output end of the exhaust fan is close to the electric heating grid.

[0025] By adopting the above technical solution, by setting up heating components, the guide tube, the electric heating grid, and the exhaust fan can form a structure for heating a local area of ​​the display, which can simulate a high-temperature environment in a local area of ​​the display. By limiting the electric heating grid and the exhaust fan through the guide tube, when the electric heating grid heats the output end of the guide tube, the exhaust fan can send air out from the guide tube, allowing the air to carry heat and flow to the display and its surroundings, thus achieving the effect of simulating a local high-temperature environment for the display.

[0026] (III) Beneficial Effects Compared with the prior art, the present invention provides an automatic detection device for online defect marking of a display screen, which has the following advantages: This automatic online defect marking display screen detection device, through the setting of a fixing mechanism, allows the support component to form a structure that provides limiting for the testing mechanism together with the adaptation component, transmission component, adjustment component, and positioning component. It can also drive the testing mechanism to adapt to the shape of the current display and position the testing mechanism in localized areas of the display where multiple defects need to be detected. Simultaneously, it can cooperate with a robotic arm, allowing the robotic arm to drive the fixing mechanism to simulate the motion of the testing mechanism and the display together, mimicking a scenario of violent shaking. A support plate, support frame, and arc frame form a structure supporting the adaptation component. As the robotic arm swings and shakes, it drives the adaptation component to swing and shake the entire fixing mechanism and the entire testing mechanism, simulating the motion environment. An adaptation electric cylinder, sliding sleeve, and sliding plate form a structure that guides the transmission component. It can move along the arc-shaped frame to guide the position of the transmission component, moving it to the required limit position of the display. The fixed angle plate, electric winch, non-powered winch and gear form a transmission structure for the adjustment component, which can change the length of the adjustment component, thereby adjusting the bending degree of the positioning component, so that it can drive the test mechanism to clamp and fix the display. The guide wheel, bending line and extension line form a structure to adjust the bending degree of the positioning component, which can adjust the bending degree of the positioning component, so that it can drive the test mechanism to move towards the display and adapt to the shape of the display. The positioning rod, adjusting electric cylinder and limit plate form a limit structure for the test mechanism, and can adapt to the error caused by the elongation and shortening of the bending line and extension line, further driving the test mechanism to adapt to the shape of the display. This online defect marking automatic display screen detection device, through the setting of a testing mechanism, allows the detection component to form a structure with a clamping component, a humidification component, and a heating component to perform visual inspection and marking of local areas of the display. Simultaneously, it can heat and humidify the area, simulating environmental changes in humidity and temperature. A positioning seat, positioning spring rod, limiting frame, and industrial camera form a structure to limit the clamping component, allowing the testing mechanism to move synchronously to the desired fixed structure of the display as the limiting plate moves. A reset spring rod, rotating block, and soft sleeve rod form a clamping structure to hold the display's surface. A pressure pump, water valve, and atomizing nozzle form a humidification structure for the display. A guide pipe, electric heating grid, and exhaust fan form a heating structure for local areas of the display, simulating a high-temperature environment in those areas. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1 Please see Figure 1-5An automatic detection device for online defect marking displays includes a fixing mechanism 1. A robotic arm 3 is mounted on the front side of the fixing mechanism 1. The fixing mechanism 1 includes a support component 11, an adaptation component 12, a transmission component 13, an adjustment component 14, and a positioning component 15. The adaptation component 12 is located on the front side of the support component 11, the transmission component 13 is located on the surface of the adaptation component 12, the adjustment component 14 is located at the output end of the transmission component 13, and the positioning component 15 is located inside the adjustment component 14. By setting the fixing mechanism 1, the support component 11 can interact with the adaptation component 12, the transmission component 13, and the adjustment component 15. The segment component 14 and the positioning component 15 form a structure that provides a limit to the testing mechanism 2, and can drive the testing mechanism 2 to adapt to the shape of the current display, allowing the testing mechanism 2 to be located in local areas of the display where multiple defects need to be detected. Simultaneously, it can cooperate with the robotic arm 3, allowing the robotic arm 3 to drive the fixing mechanism 1 to simulate the movement of the testing mechanism 2 and the display together, simulating a scene of violent shaking. The support plate 111, support frame 112, and arc frame 113 form a structure that supports the adaptation component 12. As the robotic arm 3 swings and shakes, it can drive the adaptation component 12 to fix the display. The entire mechanism 1 and the entire testing mechanism 2 swing and shake to simulate the motion environment. The electric cylinder 121, along with the sliding sleeve 122 and the sliding plate 123, forms a structure that guides the transmission component 13, allowing it to move along the arc-shaped frame 113. This guides the position of the transmission component 13, displacing it to the required limit position on the display. The fixed angle plate 131, along with the electric winch 132, the non-powered winch 133, and the gear 134, forms a transmission structure for the adjustment component 14. This allows the length of the adjustment component 14 to be changed, thereby adjusting the bending degree of the positioning component 15. This allows the testing mechanism 2 to clamp and fix the display. The guide wheel 141, along with the bending line 142 and the extension line 143, forms a structure to adjust the bending degree of the positioning component 15. This allows the bending degree of the positioning component 15 to be adjusted, thereby enabling it to move the testing mechanism 2 toward the display to adapt to the shape of the display. The positioning rod 151, along with the adjusting electric cylinder 152 and the limiting plate 153, forms a structure to limit the testing mechanism 2 and can accommodate the errors caused by the elongation and shortening of the bending line 142 and the extension line 143, further enabling the testing mechanism 2 to adapt to the shape of the display.

[0031] The support assembly 11 includes a support plate 111, a support frame 112, and an arc-shaped frame 113. The rear side of the support plate 111 is bolted to the output end of the robotic arm 3. Four support frames 112 are bolted to the four corners of the support plate 111, and four arc-shaped frames 113 are bolted to the top, bottom, and sides of the support frame 112. By setting the support assembly 11, the support plate 111, support frame 112, and arc-shaped frame 113 form a structure that supports the robotic arm 3. The shaking causes the adaptation component 12 to swing and shake the entire fixed mechanism 1 and the test mechanism 2, thus simulating the motion environment. With the output end of the robotic arm 3 as the support point, the support plate 111 can move synchronously with the displacement of the robotic arm 3. The support frame 112 can use the four corners of the support plate 111 as support points to provide stable support for the arc frame 113. The arc frame 113 can guide and limit the displacement of the adaptation component 12 in an arc path, avoiding excessive displacement that would prevent it from effectively adapting to the shape of the current display.

[0032] The adaptation component 12 includes adaptation cylinders 121, sliding sleeves 122, and sliding plates 123. Eight adaptation cylinders 121 are rotatably connected to the top, bottom, and both sides of the front side of the support plate 111. The sliding sleeves 122 are slidably connected to the output ends of the adaptation cylinders 121. The sliding plates 123 are bolted to the rear side of the sliding sleeves 122. The surface of the sliding plates 123 is slidably connected to the inner side of the arc-shaped frame 113. By setting the adaptation component 12, the adaptation cylinders 121, sliding sleeves 122, and sliding plates 123 form a structure that guides the transmission component 13. The transmission component 13 can move along the arc frame 113, thereby guiding its position to the required limiting position of the display. By driving the transmission component 13 with the adaptation cylinder 121, the transmission component 13 can be centered on the display and adapt to the shape of the display. The slide plate 123 moves along the arc frame 113 with the sliding sleeve 122 on the adaptation cylinder 121, which further increases the stability of the adaptation cylinder 121 when limiting the display under the limiting of the sliding sleeve 122 and the slide plate 123.

[0033] The transmission assembly 13 includes a fixed angle plate 131, an electric winch 132, a non-powered winch 133, and gears 134. The fixed angle plate 131 is bolted to the output end of the electric cylinder 121. The electric winch 132 is bolted to the bottom rear side of the fixed angle plate 131, and the non-powered winch 133 is bolted to the top rear side of the fixed angle plate 131. Two gears 134 are bolted to the surfaces of the output shafts of the electric winch 132 and the non-powered winch 133, respectively. The gears 134 mesh with each other. By setting the transmission assembly 13, the fixed angle plate 131, the electric winch 132, the non-powered winch 133, and the gears 134 form a complete system. To adjust the transmission structure of component 14, the length of component 14 can be changed, thereby adjusting the bending degree of positioning component 15, so that it can drive the testing mechanism 2 to clamp and fix the display. By fixing the angle plate 131 to limit the electric winch 132 and the unpowered winch 133, when the electric winch 132 is operating, it can drive the gear 134 to rotate the gear 134 on the unpowered winch 133 in the opposite direction. Thus, when the electric winch 132 is rotating in the forward direction, the gear 134 rotates the unpowered winch 133 in the reverse direction, so that the electric winch 132 and the unpowered winch 133 can maintain the same speed to wind and unwind the adjustment component 14.

[0034] The adjusting component 14 includes a guide wheel 141, a bending wire 142, and an extension wire 143. The bending wire 142 is installed at the output end of the electric winch 132, and the extension wire 143 is installed at the output end of the non-powered winch 133. The guide wheel 141 is located on the opposite side of the bending wire 142 and the extension wire 143. By setting the adjusting component 14, the guide wheel 141, the bending wire 142, and the extension wire 143 form a structure for adjusting the bending degree of the positioning component 15, thereby adjusting the bending range of the positioning component 15. The guide wheel 141 guides the bending wire 142 and the extension wire 143. When the bending wire 142 is wound and released by the electric winch 132, the unpowered winch 133 can synchronously wind and release the extension wire 143 in the opposite direction. When the bending wire 142 shortens, the extension wire 143 will extend, and the positioning component 15 will bend. Conversely, the positioning component 15 will straighten.

[0035] The positioning assembly 15 includes a positioning rod 151, an adjusting electric cylinder 152, and a limiting plate 153. The positioning rod 151 is bolted to the rear side of the fixed angle plate 131. The adjusting electric cylinder 152 is rotatably connected to the rear side of the positioning rod 151. The limiting plate 153 is bolted to the output end of the adjusting electric cylinder 152. The top and bottom of the positioning rod 151 are bolted to the side opposite to the guide wheel 141. The bottom of the front side of the limiting plate 153 is bolted to the bending line 142, and the top of the front side of the limiting plate 153 is bolted to the extension line 143. By setting the positioning assembly 15, the positioning rod 151... The positioning rod 151, the adjusting electric cylinder 152, and the limiting plate 153 can form a structure that limits the testing mechanism 2 and can accommodate the errors caused by the elongation and shortening of the bending wire 142 and the stretching wire 143. This further drives the testing mechanism 2 to adapt to the shape of the display. Through the bendable limiting structure formed by the positioning rod 151 and the adjusting electric cylinder 152, the limiting plate 153 can drive the adjusting electric cylinder 152 to rotate along the positioning rod 151 as the bending wire 142 and the stretching wire 143 elongate and stretch, thereby achieving the effect of driving the testing mechanism 2 to move synchronously and adapt to the shape of the current display.

[0036] The working principle of this embodiment is as follows: First, when it is necessary to limit the position of the display, the adapting electric cylinder 121, the electric winch 132, and the adjusting electric cylinder 152 are energized and started. Then, they are connected to an external PLC controller. The user then operates the PLC controller to control them sequentially, causing the adapting electric cylinder 121 to drive the fixed angle plate 131, moving the positioning component 15 and the testing mechanism 2 to the edge of the display. Then, the adapting electric cylinder 121 will adapt to the shape of the display by moving and rotating along the sliding sleeve 122 and the sliding plate 123 within the arc frame 113 until it adapts to the shape of the display. Then, the electric winch... Machine 132 drives gear 134 to rotate the unpowered winch 133 in the opposite direction, causing the electric winch 132 and the unpowered winch 133 to drive the bending wire 142 and the extending wire 143 to move along the guide wheel 141, so that the bending wire 142 pulls the limiting plate 153, and the extending wire 143 is released to adapt to the movement of the bending wire 142. The limiting plate 153 then drives the adjusting cylinder 152 to rotate along the positioning rod 151 until the limiting plate 153 drives the test mechanism 2 to move to the required clamping position of the display. After the test mechanism 2 clamps the display stably, the robotic arm 3 will drive the support plate 111 to shake to simulate motion.

[0037] Example 2 refer to Figure 6-9An automatic display screen inspection device for online defect marking further includes a testing mechanism 2. The testing mechanism 2 includes a detection component 21, a clamping component 22, a humidifying component 23, and a heating component 24. The detection component 21 is located on the side of the positioning component 15 away from the transmission component 13. The clamping component 22 is located at the bottom of the detection component 21. The humidifying component 23 is located on the surface of the detection component 21. The heating component 24 is located on the surface of the detection component 21. The output end of the robotic arm 3 is bolted to the rear side of the support component 11. By setting up the testing mechanism 2, the detection component 21, together with the clamping component 22, the humidifying component 23, and the heating component 24, can form a structure for visual inspection and marking of a local area of ​​the display screen. Furthermore, it can simultaneously detect defects and heat the affected area. Humidification is used to simulate environmental changes in humidity and temperature. The positioning seat 211, positioning spring rod 212, limiting frame 213 and industrial camera 214 can form a structure to limit the clamping component 22. As the limiting plate 153 moves, the test mechanism 2 can move synchronously to the structure that the display needs to be fixed. The reset spring rod 221, rotating block 222 and soft sleeve rod 223 form a clamping structure for the display. The display's surface can be clamped. The pressurizing pump 231, water valve 232 and atomizing nozzle 233 can form a humidification structure for the display. The guide pipe 241, electric heating grid 242 and exhaust fan 243 can form a heating structure for local areas of the display, which can simulate the high temperature environment of local areas of the display.

[0038] The detection component 21 includes a positioning seat 211, a positioning spring rod 212, a limiting frame 213, and an industrial camera 214. The positioning seat 211 is bolted to the rear side of the limiting plate 153, the positioning spring rod 212 is bolted to the inner side of the positioning seat 211, the limiting frame 213 is rotatably connected to the surface of the positioning seat 211, and the inner side of the limiting frame 213 is rotatably connected to the side of the positioning spring rod 212 away from the positioning seat 211. The industrial camera 214 is bolted to the surface of the limiting frame 213, and the spring end of the positioning spring rod 212 is bolted to the inner side of the positioning seat 211 and the inner side of the limiting frame 213, respectively. By setting the detection component 21, the positioning seat 211, the positioning spring rod 212, the limiting frame 213, and the industrial camera 214 are connected. The frame 213 and the industrial camera 214 can form a structure that limits the clamping component 22. As the limiting plate 153 moves, the test mechanism 2 can move synchronously to the structure required to fix the display. The positioning seat 211, with the limiting plate 153 as the support point, can limit the positioning spring rod 212 and the limiting frame 213. The positioning spring rod 212 applies elastic force to the limiting frame 213 through its own elastic force, so that the limiting frame 213 always remains reset through elastic force when it rotates to adapt to the shape of the display, thereby stably clamping the display. The industrial camera 214 can perform visual inspection on the clamping point of the clamping component 22 and mark the defect at the position through its own visual inspection.

[0039] The clamping assembly 22 includes a return spring rod 221, a rotating block 222, and a soft sleeve rod 223. The return spring rod 221 is bolted to the bottom of the positioning seat 211. The rotating block 222 is rotatably connected to the surface of the return spring rod 221. The spring ends of the return spring rod 221 are bolted to the front and rear sides of the inner side of the rotating block 222. The soft sleeve rod 223 is bolted to both sides of the bottom of the rotating block 222. By setting the clamping assembly 22, the return spring rod 221, the rotating block 222, and the soft sleeve rod 223 form a structure for clamping the monitor, which can clamp the surface of the monitor. The return spring rod 221 limits the rotating block 222 with the limiting frame 213 as the support point. The rotating block 222, which consists of two rotating structures, can maintain the elastic force of mutual reset under the elastic force of the limiting ends of the return spring rod 221. This can drive the soft sleeve rod 223 connected to it to move towards the monitor, generating a clamping force to hold the monitor, and finally achieving the effect of fixing the monitor.

[0040] The humidification component 23 includes a pressure pump 231, a water valve 232, and an atomizing nozzle 233. The pressure pump 231 is bolted to the side of the limiting frame 213 away from the flexible sleeve rod 223. The water valve 232 is connected to the input end of the pressure pump 231, and the atomizing nozzle 233 is connected to the output end of the pressure pump 231. The output end of the atomizing nozzle 233 is close to the flexible sleeve rod 223. By setting the humidification component 23, the pressure pump 231, the water valve 232, and the atomizing nozzle 233 can form a structure for humidifying the display. By humidifying the environment around the display, the effect of simulating the humidity environment is achieved. Through the water valve 232, an external water supply device can be connected, allowing the pressure pump 231 to draw in water, pressurize it, and send it to the atomizing nozzle 233. After being atomized by the atomizing nozzle 233, the water is sprayed onto the display and its surroundings to simulate a local humidity environment.

[0041] The heating component 24 includes a guide pipe 241, an electric heating grid 242, and an exhaust fan 243. The guide pipe 241 is bolted to the side of the limiting frame 213 away from the atomizing nozzle 233. The electric heating grid 242 is bolted to the output end of the guide pipe 241. The exhaust fan 243 is bolted to the inside of the guide pipe 241, with its output end close to the electric heating grid 242. By setting the heating component 24, the guide pipe 241, the electric heating grid 242, and the exhaust fan 243 can form a structure for heating a local area of ​​the display, simulating a high-temperature environment in a local area of ​​the display. By limiting the electric heating grid 242 and the exhaust fan 243 through the guide pipe 241, the exhaust fan 243 can send air out of the guide pipe 241 while the electric heating grid 242 heats the output end of the guide pipe 241, allowing the air to carry heat and flow to the display and its surroundings, thus simulating a local high-temperature environment in the display.

[0042] The working principle of this embodiment is as follows: When clamping the monitor and simulating various situations, the two flexible sleeve rods 223 adapt to the shape of the monitor. When the return spring rod 221 resets the rotating block 222, the monitor is clamped. When the limiting frame 213 rotates to adapt to the shape of the monitor, it is held in place by the elastic force of the positioning spring rod 212, further stabilizing the monitor. When simulating high humidity local areas, the water valve 232 is connected to an external water supply device to allow the pressure pump to operate. Water is pumped in and pressurized and delivered to the atomizing nozzle 233. The atomizing nozzle 233 then atomizes the water and sprays it onto the display. When a high-temperature local area environment simulation is required, the electric heating network 242 heats the output end of the guide pipe 241. When the exhaust fan 243 blows air to the output end of the guide pipe 241, the airflow passes through the heating of the electric heating network 242 and is blown onto the display. When the display has defects due to various tests, the industrial camera 214 records and marks the defects through visual acquisition.
