The screen patch detection mechanism 1 is arranged between the feeding conveyor belt 3 and the material feeding conveyor belt 4. The material in place vision sensor 5 is arranged above the feeding conveyor belt 3. After the material in place vision sensor 5 detects that the glass to be inspected is in place, the first manipulator 6 grabs the screen to be inspected on the feeding conveyor belt 3 and moves it to the screen patch detection mechanism 1 for patch detection, and the second manipulator 7 grabs the screen after the patch detection is completed and moves it to the material feeding conveyor belt 4.

[0034] Specifically, the material in place vision sensor 5 includes, but is not limited to, a laser scanner, a line array and area array CCD camera, a TV camera, etc. These devices are all standard parts that can be purchased on the market and will not be elaborated here one by one. The frame 2 is used to support and fix each component of the entire device to ensure the stability and accuracy of the device during operation. The feeding conveyor belt 3 is used to transport the screen glass to be detected from the upstream process to the detection area of the device. The length and speed of the feeding conveyor belt 3 can be adjusted according to actual production requirements to ensure the coherence of the production rhythm.

The first manipulator 6 is used to grab the screen to be inspected from the feeding conveyor belt 3 and place it into the screen patch detection mechanism 1. The second manipulator 7 is used to grab the screen after the detection is completed from the screen patch detection mechanism 1 and place it on the material feeding conveyor belt 4 for subsequent process treatment. The material feeding conveyor belt 4 is used to transport the screen that has completed the detection to the downstream process. Similar to the feeding conveyor belt 3, its length and speed can be adjusted according to production requirements.

[0035] Through the automatic grasping and handling of the first manipulator 6 and the second manipulator 7 in the present utility model, manual operation is reduced, and the safety and efficiency of production are improved. At the same time, the combined design of the feeding conveyor belt 3, the screen patch detection mechanism 1 and the material feeding conveyor belt 4 realizes the automation and continuity of the detection process, further improving the overall production efficiency.

After the lower vision sensor 12 takes a photo of the back of the screen to be inspected, the screen to be inspected is placed on the vision detection platform 13, and then the upper vision sensor 11 takes a photo of the front of the screen to be inspected.

[0037] The upper vision sensor 11 and the lower vision sensor 12 include, but are not limited to, laser scanners, line array and area array CCD cameras, TV cameras, etc. These devices are all standard components that can be purchased on the market and will not be elaborated here one by one.

[0038] When performing detection, first use the first manipulator 6 to grasp the screen to be detected and ensure its correct position. After the lower vision sensor 12 takes a picture of the back of the screen, the screen to be detected is placed at the specified position on the vision detection platform 13. Then, the upper vision sensor 11 takes a picture of the front of the screen to be detected to obtain detailed image data. By using the upper vision sensor 11 and the lower vision sensor 12 to take pictures of the screen to be detected, there is no need to use a flipping structure to flip the screen to be detected as in the prior art, reducing the use of components and simplifying the detection process, thereby reducing the detection cost and improving the detection efficiency.

[0048] Specifically, one end of the transverse mounting block 162 is connected to the column 161, and the other end is provided with a mounting seat for fixing the upper vision sensor 11. The column 161 is vertically fixed on the edge of the vision detection platform 13 and is firmly connected to the vision detection platform 13 through the fixed base at the bottom.

[0049] The column 161 is cylindrical in shape and can be made of high-strength materials such as stainless steel or aluminum alloy to ensure that it can provide sufficient supporting force during the detection process. The transverse mounting block 162 can adopt a rectangular plate structure, and its length is designed according to the width of the vision detection platform 13 to ensure that the upper vision sensor 11 can cover the upper area of the entire screen to be detected.

[0050] By adopting the combined structure of the vertical column 161 and the horizontal mounting block 162, the upper vision sensor 11 can be firmly fixed above the vision detection platform 13 and accurately aligned with the upper surface of the screen to be inspected for photographing. The vertical column 161 provides vertical support, ensuring the stability of the horizontal mounting block 162. The extended design of the horizontal mounting block 162 enables the upper vision sensor 11 to be detected at the optimal position, thereby improving the accuracy and stability of the detection.

[0051] Please refer to Figure 6 , the horizontal mounting block 162 includes a first connecting portion 1621, a second connecting portion 1622, and a third connecting portion 1623.

The other end of the second connecting portion 1622 is connected to one end of the third connecting portion 1623 by a bolt, and the other end of the third connecting portion 1623 is fixedly connected to the upper vision sensor 11 by a bolt or a quick clamp.

[0053] By adopting the combined structure of the first connecting portion 1621, the second connecting portion 1622, and the third connecting portion 1623, the upper vision sensor 11 can be firmly fixed above the vision detection platform 13 and accurately aligned with the upper surface of the screen to be inspected for photographing.

[0054] Please refer to Figure 6 , one end of the first connecting portion 1621 connected to the vertical column 161 is provided with a fastening block 163. A socket hole is formed by connecting the fastening block 163 and the first connecting portion 1621. The first connecting portion 1621 and the fastening block 163 are sleeved on the vertical column 161 through the socket hole, and the first connecting portion 1621 and the fastening block 163 are locked and fixed by the provided fasteners.

[0055] Specifically, to achieve a firm connection, the fastener can be a bolt or a screw, etc. The fastening block 163 and the first connecting portion 1621 are locked and fixed by fasteners such as bolts or screws, so as to ensure the stable position of the first connecting portion 1621 on the column 161.

[0056] Please refer to Figure 4 , the vision detection platform 13 includes a horizontally placed plate 131 and a bottom support plate 132. The horizontally placed plate 131 is arranged above the bottom support plate 132 and is fixedly connected by a plurality of connecting brackets.

[0057] Specifically, the horizontally placed plate 131 can be made of high-strength and lightweight materials such as aluminum alloy or stainless steel, and its surface is flat and smooth, suitable for placing the screen to be inspected. The bottom support plate 132 is made of high-hardness materials such as steel plates, and its design is a base structure, providing sufficient support force and stability. The connecting brackets can adopt an L-shaped or T-shaped structure and are evenly distributed between the horizontally placed plate 131 and the bottom support plate 132, and are firmly connected by bolts or welding to ensure the stability and durability of the overall structure.

[0058] By adopting the combined structure of the horizontally placed plate 131 and the bottom support plate 132, the vision detection platform 13 has sufficient stability and load-bearing capacity, can stably support the screen to be inspected and provide a flat detection surface. The flat design of the horizontally placed plate 131 ensures the stable placement of the screen to be inspected and avoids detection errors caused by screen shaking during the detection process.

[0059] Please refer to Figure 1 , a plurality of second auxiliary light sources are arranged around the horizontally placed plate 131, used to provide auxiliary lighting to improve the effect and accuracy of vision detection.

[0060] Specifically, the second auxiliary light source can be an L light source or other high-brightness light sources to ensure sufficient lighting during the shooting process. The plurality of second auxiliary light sources are evenly distributed around the horizontally placed plate 131 and are fixed to the edge of the horizontally placed plate 131 through brackets. By using the combined structure of the horizontally placed plate 131 and the second auxiliary light sources arranged around it, uniform and sufficient auxiliary light is provided, so that the screen to be inspected can obtain a clearer and brighter image during the detection process. The uniform distribution design of the second auxiliary light sources avoids lighting dead corners and uneven phenomena, thereby improving the accuracy and consistency of image capture.

[0061] In one embodiment, the second auxiliary light source adopts an adjustable angle design, which includes a rotating shaft and a locking device, enabling each second auxiliary light source to adjust its angle around its rotating shaft, thereby adjusting the direction and range of the light illumination. Through this design, the light source angle can be flexibly adjusted according to the specific size and shape of the screen to be inspected, ensuring that sufficient light illumination can be obtained at each corner.

[0062] Please refer to Figure 2 , the screen patch detection device further includes a first driving component 61.

[0063] Specifically, the first X-axis linear module 611 is installed on the frame 2 and is used to provide linear motion in the X-axis direction. The first X-axis linear module 611 includes a linear guide rail and a driving motor. The linear guide rail is used to define the motion direction and ensure the stability of the motion.

Through the setting of the first X-axis linear module 611, precise positioning and motion of the first manipulator 6 in the X-axis direction can be achieved, facilitating the grasping and handling of the screen to be inspected.

[0064] The first Y-axis linear module 612 is connected to the first X-axis linear module 611 to form a two-degree-of-freedom motion system. The first Y-axis linear module 612 is similar to the X-axis linear module and also includes a linear guide rail and a driving motor. The driving motor controls the motion in the Y-axis direction. The setting of the first Y-axis linear module 612 enables the first manipulator 6 to move in the Y-axis direction. Through cooperation with the X-axis direction, arbitrary position positioning within the plane can be achieved.

[0065] The first lifting cylinder 613 is connected to the first Y-axis linear module 612, and its output end is connected to the first manipulator 6. The lifting cylinder includes a cylinder body and a piston rod. The piston rod is driven to move up and down inside the cylinder body by compressed gas.

[0066] The first manipulator 6 is installed at the output end of the first lifting cylinder 613, and its gripper part is used to grasp the screen to be inspected. The gripper of the manipulator is a vacuum suction cup. The motion of the first manipulator 6 in the X, Y, and Z directions enables it to flexibly grasp and handle the screen to be inspected and accurately place it into the screen patch detection mechanism 1.

[0069] Specifically, the second X-axis linear module 711 is installed on the frame 2 and arranged in parallel with the first X-axis linear module 611. The second X-axis linear module 711 includes a linear guide rail and a driving motor. The linear guide rail defines the movement path of the second manipulator 7 in the X-axis direction, and the driving motor controls the movement through a lead screw or a synchronous belt mechanism. Through the setting of the second X-axis linear module 711, the precise movement of the second manipulator 7 in the X-axis direction is achieved. In this way, the screen that has been detected can be moved from the patch detection mechanism to the feeding conveyor belt 4.

[0070] The second lifting cylinder 712 is installed on the moving part of the second X-axis linear module 711, and its output end is connected to the second manipulator 7. The lifting cylinder is driven by compressed air, and the piston rod can move up and down in the Z-axis direction. The second lifting cylinder 712 enables the second manipulator 7 to perform lifting operations in the Z-axis direction, thereby achieving the grasping and handling of screens at different heights.

[0071] The second manipulator 7 is installed at the output end of the second lifting cylinder 712, and its grasping part is used to grasp the screen that has been detected. The grasping part is a vacuum chuck.

[0072] The second driving component 71 realizes the efficient handling of the detected screen through the X-axis linear module and the lifting cylinder, simplifying the process from detection to transmission.

[0073] Please refer to Figures 2 to 3 , the screen patch detection device further includes a blanking mechanism 8. The blanking mechanism 8 includes a material transfer manipulator 81, a tray manipulator 82, a loading table 83, and a tray supply table 84. The empty tray is grasped by the tray manipulator 82 from the tray supply table 84 and placed on the loading table 83, and the material transfer manipulator 81 grasps the screen that has completed the detection from the feeding conveyor belt 4 and places it into the tray on the loading table 83.

[0074] Specifically, the material transfer manipulator 81 is used to grasp the inspected screen from the feeding conveyor belt 4 and transfer it to the tray on the loading table 83. The grasping part of the material transfer manipulator 81 is a vacuum suction cup. The tray manipulator 82 is installed between the tray supply table 84 and the loading table 83, and the grasping component of the tray manipulator is a vacuum suction cup. The tray manipulator 82 is responsible for transferring the empty tray on the tray supply table 84 to the loading table 83, so that the loading table 83 always has an empty tray waiting to be loaded, ensuring the continuity and efficiency of the entire blanking process.

[0075] The loading table 83 is used to receive the empty tray placed by the tray manipulator 82 and provide a stable platform for the material transfer manipulator 81 to place the inspected screen into the tray. By providing a stable platform, the loading table 83 enables the material transfer manipulator 81 to accurately place the screen into the tray and ensures that the tray can stably carry the screen, preventing movement and tipping during handling. The tray supply table 84 is used to provide empty trays and supply them one by one to the loading table 83 through the tray manipulator 82. The tray supply table 84 ensures the continuous supply of empty trays, preventing the entire blanking process from being interrupted due to a lack of trays and improving the automation level and production efficiency of the system.

[0076] Please refer to Figures 2 to 3 As shown in the figure, the blanking mechanism 8 further includes a third drive assembly and a fourth drive assembly. The third drive assembly includes a second Y-axis linear module 811 and a first Z-axis linear module 812. The second Y-axis linear module 811 is connected to the frame 2, and the first Z-axis linear module 812 is connected to the material transfer manipulator 81. The fourth drive assembly includes a third X-axis linear module 821 and a second Z-axis linear module 822. The third X-axis linear module 821 is connected to the frame 2, and the second Z-axis linear module 822 is connected to the tray manipulator 82.

[0077] Specifically, the second Y-axis linear module 811 is installed on the frame 2 and is used to provide linear motion in the Y-axis direction. The second Y-axis linear module includes linear guide rails and a drive motor. The linear guide rails ensure the movement path of the material transfer manipulator 81 in the Y-axis direction, and the drive motor drives the material transfer manipulator 81 to move along the Y-axis through a lead screw or synchronous belt mechanism. Through the setting of the second Y-axis linear module 811, precise positioning of the material transfer manipulator 81 in the Y-axis direction is achieved, enabling it to move flexibly between the feeding conveyor belt 4 and the loading table 83. The first Z-axis linear module 812 is installed on the moving part of the second Y-axis linear module 811, and its output end is connected to the material transfer manipulator 81.

[0078] The third X-axis linear module 821 is installed on the frame 2 and is used to provide linear motion in the X-axis direction. The third X-axis linear module 821 includes a linear guide rail and a driving motor. The linear guide rail ensures the movement path of the tray manipulator 82 in the X-axis direction, and the driving motor drives the tray manipulator 82 to move along the X-axis through a lead screw or a synchronous belt mechanism. Through the setting of the third X-axis linear module 821, accurate positioning of the tray manipulator 82 in the X-axis direction is achieved, enabling it to flexibly move between the tray supply table 84 and the loading table 83.

[0079] Please refer to Figure 1 , the frame 2 is also provided with a first lifting bin 21 and a second lifting bin 22. A first lifting linear module 211 is arranged in the first lifting bin 21, and a second lifting linear module 221 is arranged in the second lifting bin 22. The loading table 83 is connected to the first lifting linear module 211, and the tray supply table 84 is connected to the second lifting linear module 221.

[0080] Specifically, the first lifting linear module 211 is installed in the first lifting bin 21 and is used to provide lifting motion in the Z-axis direction. The first lifting linear module 211 includes a linear guide rail and a driving motor. The linear guide rail ensures the movement path of the loading table 83 during the lifting process, and the driving motor drives the loading table 83 to move up and down along the Z-axis direction through a lead screw or a synchronous belt mechanism. When the tray on the loading table 83 is full, the first lifting linear module 211 drives the loading table 83 to descend to a predetermined position to facilitate the removal of the full tray from the loading table 83.

[0081] The second lifting linear module 221 is installed in the second lifting bin 22 and is used to provide lifting motion in the Z-axis direction. The second lifting linear module 221 includes a linear guide rail and a driving motor. The linear guide rail ensures the movement path of the tray supply table 84 during the lifting process, and the driving motor drives the tray supply table 84 to move up and down along the Z-axis direction through a lead screw or a synchronous belt mechanism.

[0082] After the empty tray on the tray supply table 84 is taken away by the tray manipulator 82, the second lifting linear module 221 drives the tray supply table 84 to descend to a predetermined position to facilitate the placement of a new empty tray on the tray supply table 84.
