Abstract
Description
Technical Field
[0001] This application relates to the field of panel inspection equipment technology, and more specifically, to a panel inspection component and a panel inspection device. Background Technology
[0002] Inspection of OLED (Organic Light-Emitting Diode) panels includes, but is not limited to, the inspection of conductive particles and misalignment in IC (Integrated Circuit) and FPC (Flexible Printed Circuit). Existing panel inspection devices can interface with upstream platforms to achieve automated product inspection, after which the finished products are transported to downstream equipment by an unloading mechanism.
[0003] The product to be tested needs to be placed on the testing platform by a feeding mechanism. The platform's adsorption module then adsorbs and fixes the product, and finally, a camera component takes a picture for testing. When the product to be tested is a flexible panel, due to its soft texture, the panel will slightly warp after being placed on the testing platform. The light reflected from the panel will be deflected at an angle due to the warping, and thus cannot be captured by the camera component, resulting in a dark image captured by the camera component.
[0004] Therefore, how to improve the detection imaging effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a panel detection component to improve the detection imaging effect;
[0006] Another objective of this application is to provide a panel inspection device having the above-mentioned panel inspection components.
[0007] To achieve the above objectives, this application provides the following technical solution:

[0017] In one possible implementation, the detection platform includes an adsorption module, which includes an adsorption body and an adsorption part disposed on the adsorption body. The detection area is disposed on the adsorption part, which is used to adsorb the product to be detected. The light-gathering groove is disposed on the side of the adsorption part facing the camera assembly.
[0018] In one possible implementation, the adsorption section includes a first adsorption section and a second adsorption section arranged at intervals, with the detection area formed between the first adsorption section and the second adsorption section;
[0019] The light-gathering groove is disposed on at least one of the first adsorption part and the second adsorption part.
[0020] In one possible implementation, the second adsorption part is provided with a notch groove, the notch groove and the gap between the first adsorption part and the second adsorption part together form the detection area, and the IC area of the part to be detected corresponds to the notch groove.
[0021] In one possible implementation, the notch groove is a constriction groove, and the cross-sectional area of the notch groove gradually decreases from the lower side to the upper side of the second adsorption part.
[0022] In one possible implementation, the first adsorption part has a first adsorption area, and the first adsorption area is provided with a plurality of first adsorption holes, the first adsorption holes being used to adsorb the first area of the product to be tested.
[0023] And / or,
[0024] The second adsorption part has a second adsorption area, and the second adsorption area is provided with a plurality of second adsorption holes, which are used to adsorb the second area of the product to be tested.
[0025] In one possible implementation, the first adsorption part and the second adsorption part are disposed on the adsorption body by side connectors, wherein there are two side connectors and they are connected to both sides of the adsorption body.
[0026] The first adsorption part and the second adsorption part are directly or indirectly fixed between the two side connectors.
[0027] In one possible implementation, the first adsorption part is mounted on the side connector via a connecting plate;
[0028] And / or,
[0029] The second adsorption part is directly fixed to the side connector.
[0030] In one possible implementation, the adsorption body includes an adsorption body and a support plate disposed on the upper side of the adsorption body. The adsorption body is provided with a suction cup, and the support plate has a suction cup hole, into which the suction cup extends.
[0031] In one possible implementation, the detection platform is a plurality of platforms arranged along a first direction;

[0035] The panel inspection component provided in this application designs the light source of the offset inspection camera as a ring light source. The light from the ring light source can illuminate the product to be inspected in the inspection area from multiple angles. This helps to highlight the contour and texture information of the object's surface, which is very advantageous for inspecting flexible panel products with uneven surfaces. Moreover, the ring light source can provide a uniform light distribution, illuminating the area to be inspected around the product, which can effectively reduce the generation of shadows and reflections, so that the entire inspection area can obtain a consistent light intensity. Uniform illumination allows the offset inspection camera to clearly capture every detail of the surface of the product to be inspected, avoiding some areas being too bright or too dark due to uneven lighting, which would affect the accuracy of the inspection results.
[0036] In addition, the detection platform has a light-entry groove on the side facing the ring light source that communicates with the detection area. By creating the light-entry groove, the light emitted from the ring light source can be prevented from being blocked by the detection platform, thus reducing the amount of light entering the detection area. The light-entry groove on the detection platform increases the amount of light entering the detection area, preventing the image obtained by the offset detection camera from being dark and affecting the image quality.

[0053] This application discloses a panel detection component to improve detection imaging effect;
[0054] This application also discloses a panel detection device having the above-described panel detection components.
[0055] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0056] When a flexible panel is undergoing offset detection, the panel detection assembly moves the product to the detection platform. The product is then positioned within the detection area and detected by the camera assembly. When the product is a flexible panel, its soft texture makes it prone to wrinkles. The light reflected from the panel may be deflected due to the product's warping, causing the reflected light path angle to shift and preventing it from being captured by the camera assembly. This results in a dark image captured by the camera assembly.
[0057] Based on this, embodiments of this application disclose a panel detection component to improve detection imaging effects. For example... Figures 1-3 As shown, the panel detection component includes a detection platform 300 and a camera component 100.
[0058] The inspection platform 300 has a hollowed-out inspection area 317, which is used to arrange the part to be inspected of the product 400. When the product 400 is fixed on the inspection platform 300, the part to be inspected of the product 400 is located in the hollowed-out inspection area 317, so that the camera assembly 100 can capture an image of the part to be inspected.
[0059] When the camera assembly 100 is in the detection position, it is located below the detection platform 300, and the product 400 to be detected is fixed above the detection platform 300. The camera assembly 100 acquires an image of the part to be detected through the hollowed-out detection area 317. The camera assembly 100 is only located below the detection platform 300 during detection, but it can also remain below the detection platform 300 at all times. Those skilled in the art can choose according to their needs, as long as it can capture an image of the detection area 317 when in the detection position.
[0060] The camera assembly 100 includes at least an offset detection camera 110 for performing offset detection on the part to be inspected of the product 400 to be inspected. The IC is the core control component for the flexible panel to achieve various functions; its precise position on the flexible panel directly affects the screen's display effect, signal transmission, and overall performance. If the IC is offset, it may lead to problems such as poor circuit connections, signal transmission interruptions, and display abnormalities (e.g., some areas not displaying, color deviation, etc.). The FPC, as a bridge connecting various components of the flexible panel (such as the IC and display panel), is responsible for transmitting electrical signals and data. Offset of the FPC may cause misalignment of connection points, unstable signal transmission, affecting the display effect and functional implementation of the flexible panel, and in severe cases, may cause the screen to malfunction. Therefore, offset detection is required for all flexible panels before they leave the factory.
[0061] The offset inspection camera 110 uses a ring light source 111 as its light source. Designing the light source as a ring light source 111 allows the light from the ring light source 111 to illuminate the product 400 to be inspected in the inspection area 317 from multiple angles. This helps to highlight the contours and textures of the object's surface, which is particularly advantageous for inspecting flexible panel products with uneven surfaces. Furthermore, the ring light source 111 provides a uniform light distribution, illuminating the area to be inspected around the product 400, effectively reducing shadows and reflections, ensuring consistent illumination intensity throughout the entire inspection area 317. Uniform illumination allows the offset inspection camera 110 to clearly capture every detail of the surface of the product 400, avoiding uneven lighting that could cause some areas to be too bright or too dark, thus affecting the accuracy of the inspection results.
[0062] like Figure 7 As shown, the detection platform 300 has a light-entering groove 3122 communicating with the detection area 317 on the side facing the ring light source 111. The light-entering groove 3122 is arranged at least on one side of the detection area 317. That is, the wall thickness of the detection platform 300 near the detection area 317 is reduced to prevent the thicker plate of the detection platform 300 from blocking the light. In this embodiment, by providing the light-entering groove 3122, the light emitted from the ring light source 111 can be prevented from being blocked by the detection platform 300, thus reducing the amount of light entering the detection area 317. Providing the light-entering groove 3122 on the detection platform 300 can increase the amount of light entering the detection area 317, preventing the image obtained by the offset detection camera 110 from being dark and affecting the picture quality.
[0063] like Figure 1As shown, the ring light source 111 includes a light-emitting surface, which is a conical structure, and its diameter gradually increases along the light emission direction. In this embodiment, the ring light source 111 is designed with a conical light-emitting surface, which concentrates the light onto a specific detection area 317, i.e., onto the part of the product 400 to be inspected. This concentrated illumination method clearly illuminates the key parts of the part to be inspected, facilitating the offset detection camera 110 to capture details and improving detection accuracy.
[0064] In addition, designing the light-emitting surface of the ring light source 111 as a conical structure can more effectively concentrate the light on the part of the product to be inspected 400, reduce light waste, improve light utilization efficiency, reduce energy consumption to a certain extent, and also achieve better shooting or inspection results under the same lighting conditions.
[0065] Particles on or inside an IC's surface can affect its electrical performance and reliability. Particles can cause short circuits, leakage, and other problems, reducing the IC's lifespan and, in extreme cases, causing complete IC failure, thus affecting the normal operation of the flexible display. Particles on the FPC (Flexible Printed Circuit) can affect its electrical performance, leading to decreased insulation between circuits and increased signal interference. Furthermore, particles can wear down the FPC's surface, reducing its mechanical stability and lifespan. Therefore, all flexible displays require conductive particle testing before leaving the factory.
[0066] Based on this, in this embodiment, the camera assembly 100 also includes a particle detection camera 120 for detecting conductive particles in the product 400 to be inspected. The light source of the particle detection camera 120 is a point light source. The light emitted by the point light source radiates outward from a single point, and when the light shines on the conductive particles, it can outline the particle's contour in a more concentrated manner. Unlike other light sources (such as surface light sources, which may cause light and shadow to be averaged), the point light source can make the edges of the particles clearer under shadow contrast, allowing the particle detection camera 120 to more accurately identify the particle's shape, size, regularity, and other characteristics.
[0067] In one specific embodiment of this application, the camera assembly 100 may further include a first displacement adjustment device 150 and a second displacement adjustment device 140. An offset detection camera 110 is disposed at the output end of the first displacement adjustment device 150 to drive the offset detection camera 110 to move closer to and further away from the detection platform 300. A particle detection camera 120 is disposed at the output end of the second displacement adjustment device 140 to drive the particle detection camera 120 to move closer to and further away from the detection platform 300.
[0068] In this embodiment, the distance between the offset detection camera 110 and the product 400 to be detected can be adjusted by the first displacement adjustment device 150, thereby enabling the offset detection camera 110 to obtain a clearer image. In this embodiment, the distance between the particle detection camera 120 and the product 400 to be detected can be adjusted by the second displacement adjustment device 140, thereby enabling the particle detection camera 120 to obtain a clearer image.
[0069] In order to automatically adjust the distance between the offset detection camera 110 and the particle detection camera 120 and the product 400 to be inspected, the camera assembly 100 also includes a distance sensor 130. The distance sensor 130 is used to detect the distance to the product 400. The first displacement adjustment device 150 drives the offset detection camera 110 to move based on the distance value detected by the distance sensor 130, and the second displacement adjustment device 140 drives the particle detection camera 120 to move based on the distance value detected by the distance sensor 130.
[0070] The control system pre-stores the initial distances between the offset detection camera 110 and the particle detection camera 120 and the product 400 to be inspected (i.e., the offset detection camera 110 and the particle detection camera 120 are in their initial positions). When the difference between the distance value detected by the distance sensor 130 and the initial distance value of the offset detection camera 110 exceeds a preset difference range, the control system controls the first displacement adjustment device 150 to move the offset detection camera 110 so that the actual distance between the offset detection camera 110 and the product 400 to be inspected meets the set requirements. When the difference between the distance value detected by the distance sensor 130 and the initial distance value of the particle detection camera 120 exceeds a preset difference range, the control system controls the second displacement adjustment device 140 to move the particle detection camera 120 so that the actual distance between the particle detection camera 120 and the product 400 to be inspected meets the set requirements. It should be noted that after the product 400 to be inspected is inspected, the particle detection camera 120 and the offset detection camera 110 need to return to their initial positions.
[0071] like Figure 3 and Figure 4 As shown, in this embodiment, the detection platform 300 includes an adsorption module 310, which includes an adsorption body and an adsorption part disposed on the adsorption body. The adsorption body and the adsorption part are used to adsorb different parts of the product 400 to be tested.
[0072] The detection area 317 is disposed on the adsorption part; that is, in this embodiment, an adsorption part is added around the detection area 317 to reinforce the part of the product 400 to be tested located in the detection area 317 and improve the stability of the part to be tested. Figure 7As shown, the adsorption part is closer to the test part of the product to be tested 400 than the adsorption body, so the light-gathering groove 3122 is provided on the side of the adsorption part facing the camera assembly 100.
[0073] The adsorption unit may include a first adsorption unit 311 and a second adsorption unit 312 arranged at intervals, with a detection area 317 formed between the first adsorption unit 311 and the second adsorption unit 312. A light-gathering groove 3122 is disposed on at least one of the first adsorption unit 311 and the second adsorption unit 312. Both the first adsorption unit 311 and the second adsorption unit 312 have a negative pressure adsorption function, used to adsorb and fix the product 400 to be tested, so that the product 400 to be tested can be fixed on the adsorption module 310 for conductive particle detection and offset detection.
[0074] A detection area 317 is formed between the first adsorption part 311 and the second adsorption part 312. The camera assembly 100 is located below the adsorption module 310 and performs detection on the detection area 317. After the product to be tested 400 is adsorbed onto the adsorption module 310, the part to be tested (e.g., the IC area and part of the FPC area) of the product to be tested 400 is located in the detection area 317. When the camera assembly 100 is located below the adsorption module 310 and takes a picture of the detection area 317, it can perform visual inspection on the part to be tested located in the detection area 317. In this embodiment, by fixing the product to be tested 400 on both sides of the detection area 317 with the first adsorption part 311 and the second adsorption part 312, reliable fixation of the part to be tested can be achieved, preventing warping of the part to be tested, thereby improving the detection imaging effect.
[0075] like Figure 5 As shown, the first adsorption part 311 has a first adsorption region, and the first adsorption region is provided with a plurality of first adsorption holes 3113. The first adsorption holes 3113 are used to adsorb the product 400 to be tested in the first region. The first adsorption holes 3113 can be densely distributed in the first adsorption region of the first adsorption part 311. The arrangement density of the first adsorption holes 3113 in the first adsorption region can be designed by those skilled in the art according to their needs. Each first adsorption hole 3113 can generate a negative pressure to adsorb the product 400 to be tested. All the first adsorption holes 3113 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each first adsorption hole 3113 and maintain the same or similar negative pressure suction force for each first adsorption hole 3113.
[0076] like Figure 3As shown, the second adsorption section 312 has a second adsorption region, and the second adsorption region is provided with a plurality of second adsorption holes 3121. The second adsorption holes 3121 are used to adsorb the product 400 to be tested in the second region. The second adsorption holes 3121 can be densely distributed in the second adsorption region of the second adsorption section 312. The arrangement density of the second adsorption holes 3121 in the second adsorption region can be designed by those skilled in the art according to their needs. Each second adsorption hole 3121 can generate a negative pressure to adsorb the product 400 to be tested. All the second adsorption holes 3121 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each second adsorption hole 3121 and maintain the same or similar negative pressure suction force for each second adsorption hole 3121.
[0077] The first and second regions of the product to be tested 400 are distributed on both sides of the part to be tested, allowing the first adsorption part 311 and the second adsorption part 312 to add fixing points near the part to be tested, thereby ensuring the stability of the part to be tested and improving the detection imaging effect. Moreover, the first and second adsorption regions adopt a microporous adsorption structure, which is particularly suitable for fixing flexible panels. Since the pore size of the first adsorption hole 3113 and the second adsorption hole 3121 is small and densely distributed, it is not easy to adsorb and deform the flexible panel.
[0078] like Figure 3 and Figure 7 As shown in a specific embodiment of this application, the second adsorption part 312 is provided with a notch groove 3123. The notch groove 3123, together with the gap between the first adsorption part 311 and the second adsorption part 312, forms a detection area 317, and the IC area of the product to be detected corresponds to the notch groove 3123. In this embodiment, by providing the notch groove 3123, the area of the detection area 317 is expanded, and the notch groove 3123 can correspond to the IC area of the product to be detected 400. Moreover, second adsorption holes 3121 are provided around the notch groove 3123, thereby increasing the fixing effect on the IC area (the three sides of the IC area are all adsorbed and fixed by the second adsorption holes 3121).
[0079] Furthermore, the notch groove 3123 can be a constricted groove, and the cross-sectional area of the notch groove 3123 gradually decreases from the lower side to the upper side of the second adsorption part 312. In this embodiment, by designing the sidewall of the notch groove 3123 as an inclined sidewall, the amount of light entering the camera assembly 100 can also be increased, thereby improving the detection imaging effect.
[0080] In a specific embodiment of this application, the first adsorption part 311 and the second adsorption part 312 are disposed on the adsorption body through the side connector 315. In order to improve the fixing effect of the first adsorption part 311 and the second adsorption part 312, there can be two side connectors 315, which are respectively connected to both sides of the adsorption body.
[0081] The first adsorption part 311 and the second adsorption part 312 are directly or indirectly fixed between the two side connectors 315. In this embodiment, the first adsorption part 311 and the second adsorption part 312 are supported by the two side connectors 315, which can ensure the reliability of the fixation of the first adsorption part 311 and the second adsorption part 312.
[0082] The first adsorption part 311 can be indirectly mounted on the side connector 315 via the connecting plate 313; the second adsorption part 312 can be directly fixed to the side connector 315. The position of the first adsorption part 311 can be adjusted via the connecting plate 313, thereby adjusting the positional relationship between the first adsorption part 311 and the second adsorption part 312. By adjusting the position of the first adsorption part 311, the width of the detection area 317 can be adjusted.
[0083] like Figure 6 and Figure 8 As shown, the side connector 315 has a plurality of first fastening holes 3153 spaced apart at one end away from the adsorption body. Each first fastening hole 3153 is arranged at intervals along the extension direction of the side connector 315, that is, each first fastening hole 3153 is arranged along the arrangement direction from the first adsorption part 311 to the second adsorption part 312.
[0084] The connecting plate 313 is provided with a first strip-shaped hole 31311 extending along a first adjustment direction, which is the direction from the first adsorption part 311 to the second adsorption part 312. Fasteners for fixing the connecting plate 313 pass through the first strip-shaped hole 31311 and are fastened to at least one of the first fastening holes 3153. When it is necessary to adjust the position of the first adsorption part 311 along the first adjustment direction, simply loosen the fastener, then slide the first adsorption part 311 to adjust its position in the first adjustment direction. After adjustment, tighten the fastener. If it is necessary to further increase the adjustment position of the first adsorption part 311 in the first adjustment direction, the fastener can be fixed to other first fastening holes 3153 to further change the position of the first adsorption part 311.
[0085] like Figure 5 and Figure 6As shown, the first adsorption part 311 is provided with a plurality of second fastening holes 31111 arranged along the second adjustment direction, which is perpendicular to the first adjustment direction. The connecting plate 313 is provided with a second strip-shaped hole 31321 extending along the second adjustment direction. The fastener that fixes the first adsorption part 311 passes through the second strip-shaped hole 31321 and is fastened to at least one of the second fastening holes 31111. When it is necessary to adjust the position of the first adsorption part 311 along the second adjustment direction, simply loosen the fastener, then slide the first adsorption part 311 along the second adjustment direction to adjust its position. After adjustment, tighten the fastener.
[0086] In summary, the position of the first adsorption part 311 in the first adjustment direction and the second adjustment direction can be adjusted by the connecting plate 313. In turn, the position of the first adsorption part 311 in the plane can be adjusted according to the requirements. That is, the adsorption area of the first adsorption part 311 can be adjusted according to the size characteristics of the product 400 to be tested.
[0087] Those skilled in the art will understand that the levelness of the first adsorption section 311 will affect the levelness of the adsorbed product 400 to be tested, and thus affect the testing quality of the product 400. The levelness of both the connecting plate 313 and the first adsorption section 311 after installation will ultimately affect the levelness of the product 400 to be tested. Therefore, the levelness of the product 400 to be tested can be adjusted by adjusting the levelness of the connecting plate 313 and the first adsorption section 311.
[0088] like Figure 6 As shown, in this embodiment, a plurality of first adjustment holes 31312 and a plurality of second adjustment holes 31322 are provided on the connecting plate 313.
[0089] Those skilled in the art can, as needed, thread a first adjusting screw into the corresponding first adjusting hole 31312, with the end of the first adjusting screw abutting against the side connector 315. At least two first adjusting holes 31312 can be arranged along the extension direction of the first strip hole 31311. When the levelness of the connecting plate 313 exceeds the threshold range, the fastener on the lower side (the fastener used to fix the connecting plate 313 and the side connector 315; for ease of understanding, the fastener on the lower side is defined as the first target fastener) can be loosened, and then the first adjusting screw near the first target fastener can be screwed in to raise the height of the corresponding side of the connecting plate 313, thereby adjusting the levelness until it meets the design requirements.
[0090] Alternatively, a second adjusting screw can be threaded into the corresponding second adjusting hole 31322 as needed. The end of the second adjusting screw abuts against the first adsorption part 311. At least two second adjusting holes 31322 can be arranged along the extension direction of the second strip hole 31321. When the levelness of the first adsorption part 311 exceeds the threshold range, the fastener on the lower side (the fastener used to fix the first adsorption part 311 and the connecting plate 313; for ease of understanding, the fastener on the lower side is defined as the second target fastener) can be loosened, and then the second adjusting screw near the second target fastener can be screwed in to raise the height of the corresponding side of the first adsorption part 311, thereby adjusting the levelness until it meets the design requirements.
[0091] like Figure 5 As shown in a specific embodiment of this application, the first adsorption part 311 includes a first stepped plate 3111 and a second stepped plate 3112. The first stepped plate 3111 and the second stepped plate 3112 have a stepped structure. The first stepped plate 3111 is connected to the lower side of the connecting plate 313, and the height of the second stepped plate 3112 is higher than the height of the first stepped plate 3111.
[0092] The second fastening hole 31111 is provided on the first stepped plate 3111, and the first adsorption hole 3113 for adsorbing the product 400 to be tested is provided on the second stepped plate 3112. In this embodiment, this mounting structure allows the first stepped plate 3111, which has a lower height, to connect to the lower side of the connecting plate 313, while also ensuring that the height of the second stepped plate 3112 is the same as the height of the second adsorption part 312. Moreover, the stepped structure prevents the lower side of the first adsorption part 311 from blocking the light from the camera assembly 100.
[0093] After the first adsorption part 311 is installed, the adsorption area with the first adsorption hole 3113 can be arranged at one end close to the second adsorption part 312, and part of the material (e.g., the non-adsorption area of the second stepped plate 3112) can be removed from its upper surface. Figure 5 The thinning region 31121 in the middle is used to reduce the thickness of the non-adsorption region, so that the part of the second step plate 3112 near the connecting plate 313 can be coplanar with the upper surface of the connecting plate 313.
[0094] like Figure 6As shown, the connecting plate 313 may include a connecting seat 3131 and a connecting plate main body 3132. A first strip-shaped hole 31311 is provided in the connecting seat 3131, and a second strip-shaped hole 31321 is provided in the connecting plate main body 3132, facing the side of the side connector 315. The connecting seat 3131 protrudes from the connecting plate main body 3132. In this embodiment, the connecting seat 3131 is connected to the side connector 315, and the side of the connecting seat 3131 facing the side connector 315 protrudes from the connecting plate main body 3132, which allows the height of the connecting plate main body 3132 to be raised to facilitate the connection between the first step plate 3111 and the connecting plate main body 3132. A clearance groove 31323 may be provided in a portion of the connecting plate main body 3132 to avoid other components of the equipment.
[0095] like Figure 8 As shown, the side connector 315 is provided with a limiting groove 3151, and the bottom wall of the limiting groove 3151 is provided with a third fastening hole 3152. The second adsorption part 312 is provided with a mounting hole 3124. The end of the second adsorption part 312 is fitted into the limiting groove 3151, and the fastener that fixes the second adsorption part 312 passes through the mounting hole 3124 and is fastened to the third fastening hole 3152. The limiting groove 3151 can position the second adsorption part 312, so that after the end of the second adsorption part 312 is fitted into the limiting groove 3151, the mounting hole 3124 and the third fastening hole 3152 can be easily aligned, facilitating the insertion of the fastener. Moreover, the width of the limiting groove 3151 can be designed to be greater than the width of other positions on the side connector 315, thereby improving the support effect on the second adsorption part 312.
[0096] The limiting slot 3151 is located in the middle area of the side connector 315. One end of the limiting slot 3151 is the first mounting area, and the other end is the second mounting area. The side wall of the first mounting area is provided with a positioning hole 3155 and a mounting hole 3154. A pin passes through the positioning hole 3155 to position the side connector 315 on the adsorption body, and a fastener passes through the mounting hole 3154 to lock the side connector 315 on the adsorption body. A first fastening hole 3153 is provided in the second mounting area to fix the connecting plate 313 to the second mounting area.
[0097] Those skilled in the art will understand that the level of the second adsorption section 312 will affect the level of the adsorbed product 400 to be tested, which will also affect the detection quality of the product 400 to be tested. Therefore, the level of the product 400 to be tested can be adjusted by adjusting the level of the second adsorption section 312.
[0098] like Figure 7As shown, the second adsorption part 312 is provided with multiple third adjustment holes 3125. A third adjustment screw can be threaded into the corresponding third adjustment hole 3125 as needed, with the end of the third adjustment screw abutting against the side connector 315. When the levelness of the second adsorption part 312 exceeds a threshold range, the fastener on the lower side (i.e., the fastener used to fix the second adsorption part 312 and the side connector 315; for ease of understanding, the fastener on the lower side is defined as the third target fastener) can be loosened. Then, the third adjustment screw near the third target fastener can be screwed in to raise the height of the corresponding side of the second adsorption part 312, thereby adjusting the levelness until it meets the design requirements.
[0099] like Figure 3 As shown in a specific embodiment of this application, the adsorption body includes an adsorption body 316 and a support plate 314 disposed on the upper side of the adsorption body 316. A suction cup 3161 is disposed on the adsorption body 316, and a suction cup hole is formed on the support plate 314, into which the suction cup 3161 extends. Since the suction cup 3161 cannot guarantee the flatness of the product 400 to be tested, especially when the product 400 is a flexible screen, if only the suction cup 3161 is used to support the flexible screen, the flatness of the flexible screen cannot be guaranteed. In this embodiment, a support plate 314 is disposed on the upper side of the adsorption body 316. By supporting the product 400 to be tested through the support plate 314, the flatness of the product 400 to be tested can be guaranteed. The support plate 314 can also be used to support the display portion of the product 400 to be tested. Furthermore, the suction cup hole on the support plate 314 allows the suction force of the suction cup 3161 to act on the product 400 to be tested, thus adsorbing and fixing the product 400 to be tested.
[0100] The levelness of the support plate 314 will affect the levelness of the adsorbed product 400 to be tested, and thus the testing quality of the product 400. Therefore, the levelness of the product 400 to be tested can be adjusted by adjusting the levelness of the support plate 314. In this embodiment, the support plate 314 is provided with a plurality of fourth adjustment holes 3141, and a fourth adjustment screw is threaded into the corresponding fourth adjustment hole 3141, with the end of the fourth adjustment screw abutting against the adsorption body 316.
[0101] When the level of the support plate 314 exceeds the threshold range, the fastener on the lower side (i.e. the fastener used to fix the support plate 314 and the adsorption body 316; for ease of understanding, the fastener on the lower side is defined as the fourth target fastener) can be loosened, and then the fourth adjusting screw near the fourth target fastener can be screwed in to raise the height of the corresponding side of the support plate 314, thereby adjusting the level until it meets the design requirements.
[0102] like Figure 2As shown in a specific embodiment of this application, the detection platform 300 consists of multiple platforms arranged along a first direction. Figure 2 In the illustrated scheme, two testing platforms 300 are provided, each equipped with a corresponding loading mechanism for placing the product to be tested on the testing platform 300 for testing. When one of the two testing platforms 300 is in testing mode, the other can perform a loading action to prepare for subsequent testing, thus avoiding idleness of the camera component 100 and improving the utilization efficiency of the camera component 100.
[0103] The panel detection assembly also includes a first displacement module 200, and a camera assembly 100 is disposed at the output end of the first displacement module 200 to drive the camera assembly 100 to reciprocate along a first direction. In this embodiment, the first displacement module 200 can drive the camera assembly 100 to reciprocate along the first direction to change the position of the camera assembly 100 in the first direction, thereby moving the camera assembly 100 below each detection platform 300 to detect the product to be detected on the corresponding detection platform 300.
[0104] Furthermore, the detection platform 300 may also include multiple adsorption modules 310, with each adsorption module 310 arranged along the first direction. Figure 3 In the illustrated scheme, each detection platform 300 is provided with two adsorption modules 310, and those skilled in the art can select the number of adsorption modules 310 according to their needs.
[0105] The detection platform 300 also includes a rotating platform 340 and a second displacement module 330. The rotating platform 340 is located at the output end of the second displacement module 330. Each adsorption module 310 is mounted on the output end of the rotating platform 340 via a mounting plate 320, allowing the rotating platform 340 to adjust the orientation of each adsorption module 310 so that each adsorption module 310 can correspond to the camera assembly 100. The mounting plate 320 has weight-reducing holes 321 between each adsorption module 310 to reduce the weight of the mounting plate 320.
[0106] The second displacement module 330 is used to drive the adsorption module 310 to reciprocate along the second direction, which intersects with the first direction. Furthermore, the second direction and the first direction can be designed to be perpendicular to each other.
[0107] When the detection platform 300 needs to move from the detection position to the receiving position, the second displacement module 330 drives the adsorption module 310 to move away from the camera assembly 100 along the second direction. When the feeding mechanism places the product to be tested on the adsorption module 310, and then the detection platform 300 needs to be moved from the receiving position to the detection position, the second displacement module 330 drives the adsorption module 310 to move closer to the camera assembly 100 along the second direction, so that when the camera assembly 100 moves along the first direction, it can move to a position below the detection platform 300 to detect the product to be tested on the detection platform 300.
