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 adsorbed onto the adsorption module on the testing platform to fix it in place. Because the product is flexible, the suction cups on the existing adsorption module only adhere to the display portion, leaving the area where the IC and FPC are located unsecured. This results in warping of the area to be tested, consequently affecting the imaging results.

[0051] This application discloses an adsorption module to improve the fixation effect of the product to be tested and prevent the detection imaging effect from being affected by warping;

[0052] This application also discloses an adsorption component and a panel detection device having the above-mentioned adsorption module.

[0053] 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.

[0054] 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.

[0055] The integrated circuit (IC) is the core control component that enables various functions of a flexible screen. Its precise positioning directly affects the screen's display quality, signal transmission, and overall performance. If the IC is misaligned, it can lead to poor wiring connections, signal transmission interruptions, and display abnormalities (such as partial non-display or color deviation). The flexible printed circuit board (FPC), acting as a bridge connecting various components of the flexible screen (such as the IC and display panel), is responsible for transmitting electrical signals and data. FPC misalignment can cause misalignment of connection points, unstable signal transmission, and affect the flexible screen's display quality and functionality; in severe cases, it may even cause the screen to malfunction. Therefore, all flexible screens undergo misalignment testing before leaving the factory.

[0056] Flexible screens (such as OLED display modules) require fixation in an adsorption module before inspection by a camera assembly. Existing adsorption modules only use suction cups to hold the display portion of the product under test, leaving the areas containing the IC and FPC unsecured.

[0057] Based on this, this application discloses an adsorption module to improve the fixation effect of the product to be tested and prevent the detection imaging effect from being affected by warping.

[0058] like Figure 1 and Figure 2 As shown, the adsorption module 100 disclosed in this application includes an adsorption body and a first adsorption part 110 and a second adsorption part 120 disposed on the adsorption body. Both the first adsorption part 110 and the second adsorption part 120 have negative pressure adsorption function, which is used to adsorb and fix the product 500 to be tested, so that the product 500 to be tested can be fixed on the adsorption module 100 for conductive particle detection and offset detection.

[0059] A detection cutout area 170 is formed between the first adsorption part 110 and the second adsorption part 120. A camera assembly can be positioned below the adsorption module 100 and can detect the detection cutout area 170. After the product 500 to be tested is adsorbed onto the adsorption module 100, the portion of the product 500 to be tested (e.g., the IC area and a portion of the FPC) is located in the detection cutout area 170. When the camera assembly is positioned below the adsorption module 100 and captures an image of the detection cutout area 170, visual inspection of the portion to be tested located in the detection cutout area 170 can be performed.

[0060] The adsorption module 100 disclosed in this application embodiment has a first adsorption part 110 and a second adsorption part 120 arranged around the detection hollow area 170. When the product to be tested is adsorbed onto the adsorption module 100, the part to be tested of the product 500 is located in the detection hollow area 170, and the first adsorption part 110 and the second adsorption part 120 fix the product 500 to be tested on both sides of the detection hollow area 170, thereby achieving reliable fixation of the part to be tested, preventing warping of the part to be tested, and thus improving the detection imaging effect.

[0061] like Figure 3 As shown, the first adsorption section 110 has a first adsorption region, and the first adsorption region is provided with a plurality of first adsorption holes 113. The first adsorption holes 113 are used to adsorb the product 500 to be tested in the first region. The first adsorption holes 113 can be densely distributed in the first adsorption region of the first adsorption section 110. The arrangement density of the first adsorption holes 113 in the first adsorption region can be designed by those skilled in the art according to their needs. Each first adsorption hole 113 can generate a negative pressure to adsorb the product 500 to be tested. Each first adsorption hole 113 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each first adsorption hole 113 and maintain the same or similar negative pressure suction force for each first adsorption hole 113.

[0062] like Figure 1 As shown, the second adsorption section 120 has a second adsorption region, and the second adsorption region is provided with a plurality of second adsorption holes 121. The second adsorption holes 121 are used to adsorb the product 500 to be tested in the second region. The second adsorption holes 121 can be densely distributed in the second adsorption region of the second adsorption section 120. The arrangement density of the second adsorption holes 121 in the second adsorption region can be designed by those skilled in the art according to their needs. Each second adsorption hole 121 can generate a negative pressure to adsorb the product 500 to be tested. Each second adsorption hole 121 can be interconnected, so that a negative pressure source can be used to provide negative pressure to each second adsorption hole 121 and maintain the same or similar negative pressure suction force for each second adsorption hole 121.

[0063] The first and second adsorption regions are arranged around the detection cutout region 170, so that the first and second regions of the product to be tested 500 surround the outer side of the part to be tested of the product to be tested 500. This allows the first adsorption part 110 and the second adsorption part 120 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 113 and the second adsorption hole 121 is small and densely distributed, it is not easy to adsorb and deform the flexible panel.

[0064] like Figure 1As shown, the first adsorption part 110 and the second adsorption part 120 can be disposed on the adsorption body via side connectors 150. In order to improve the fixing effect of the first adsorption part 110 and the second adsorption part 120, two side connectors 150 can be provided, and the two side connectors 150 can be respectively connected to both sides of the adsorption body.

[0065] The first adsorption part 110 and the second adsorption part 120 can be directly or indirectly fixed between the two side connectors 150. In this embodiment, the first adsorption part 110 and the second adsorption part 120 are supported by the two side connectors 150, which can ensure the reliability of the fixation of the first adsorption part 110 and the second adsorption part 120.

[0066] The first adsorption part 110 can be indirectly mounted on the side connector 150 via the connecting plate 130, while the second adsorption part 120 can be directly fixed to the side connector 150. The position of the first adsorption part 110 can be adjusted via the connecting plate 130, thereby adjusting the positional relationship between the first adsorption part 110 and the second adsorption part 120. By adjusting the position of the first adsorption part 110, the width of the detection cutout area 170 can be adjusted.

[0067] like Figure 4 and Figure 6 As shown, the side connector 150 has a plurality of first fastening holes 153 spaced apart at one end away from the adsorption body. Each first fastening hole 153 is arranged at intervals along the extension direction of the side connector 150, that is, each first fastening hole 153 is arranged along the direction from the first adsorption part 110 to the second adsorption part 120.

[0068] The connecting plate 130 is provided with a first strip-shaped hole 1311 extending along a first direction, which is the direction from the first adsorption part 110 to the second adsorption part 120. Fasteners for fixing the connecting plate 130 pass through the first strip-shaped hole 1311 and are fastened to at least one of the first fastening holes 153. When it is necessary to adjust the position of the first adsorption part 110 along the first direction, simply loosen the fastener, then slide the first adsorption part 110 to adjust its position in the first direction. After adjustment, tighten the fastener. If it is necessary to further increase the adjustable position of the first adsorption part 110 in the first direction, the fastener can be fixed to other first fastening holes 153 to further change the position of the first adsorption part 110.

[0069] like Figure 3 and Figure 4As shown, the first adsorption part 110 is provided with a plurality of second fastening holes 1111 arranged along a second direction, which is perpendicular to the first direction. The connecting plate 130 is provided with a second strip-shaped hole 1321 extending along the second direction. The fastener that fixes the first adsorption part 110 passes through the second strip-shaped hole 1321 and is fastened to at least one of the second fastening holes 1111. When it is necessary to adjust the position of the first adsorption part 110 along the second direction, simply loosen the fastener, then slide the first adsorption part 110 along the second direction to adjust its position. After adjustment, tighten the fastener.

[0070] In summary, the position of the first adsorption part 110 in the first direction and the second direction can be adjusted by the connecting plate 130, and the position of the first adsorption part 110 in the plane can be adjusted according to the requirements. In other words, the adsorption area of ​​the first adsorption part 110 can be adjusted according to the size characteristics of the product 500 to be tested.

[0071] Those skilled in the art will understand that the levelness of the first adsorption section 110 will affect the levelness of the adsorbed product 500 to be tested, and thus affect the testing quality of the product 500. The levelness of the connecting plate 130 after installation, and the levelness of the first adsorption section 110 after installation, will ultimately affect the levelness of the product 500 to be tested. Therefore, the levelness of the product 500 to be tested can be adjusted by adjusting the levelness of the connecting plate 130 and the first adsorption section 110.

[0072] like Figure 4 As shown, in this embodiment, a plurality of first adjustment holes 1312 and a plurality of second adjustment holes 1322 are provided on the connecting plate 130.

[0073] Those skilled in the art can, as needed, thread a first adjusting screw into the corresponding first adjusting hole 1312, with the end of the first adjusting screw abutting against the side connector 150. At least two first adjusting holes 1312 can be arranged along the extension direction of the first strip hole 1311. When the levelness of the connecting plate 130 exceeds the threshold range, the fastener on the lower side (the fastener used to fix the connecting plate 130 and the side connector 150; 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 130, thereby adjusting the levelness until it meets the design requirements.

[0074] Alternatively, a second adjusting screw can be threaded into the corresponding second adjusting hole 1322 as needed. The end of the second adjusting screw abuts against the first adsorption part 110. At least two second adjusting holes 1322 can be arranged along the extension direction of the second strip hole 1321. When the levelness of the first adsorption part 110 exceeds the threshold range, the fastener on the lower side (the fastener used to fix the first adsorption part 110 and the connecting plate 130; 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 110, thereby adjusting the levelness until it meets the design requirements.

[0075] like Figure 3 As shown in a specific embodiment of this application, the first adsorption part 110 includes a first stepped plate 111 and a second stepped plate 112. The first stepped plate 111 and the second stepped plate 112 have a stepped structure. The first stepped plate 111 is connected to the lower side of the connecting plate 130, and the height of the second stepped plate 112 is higher than the height of the first stepped plate 111.

[0076] The second fastening hole 1111 is provided on the first stepped plate 111, and the first adsorption hole 113 of the first adsorption part 110 for adsorbing the product 500 to be tested is provided on the second stepped plate 112. In this embodiment, this mounting structure allows the first stepped plate 111, which has a lower height, to be connected to the lower side of the connecting plate 130, while also ensuring that the height of the second stepped plate 112 is the same as the height of the second adsorption part 120.

[0077] After installation, the adsorption area with the first adsorption hole 113 of the first adsorption part 110 can be arranged at one end close to the second adsorption part 120, and part of the material (e.g., material) can be removed from the upper surface of the non-adsorption area of ​​the second stepped plate 112. Figure 3 The thinning zone 1121 in the middle is used to reduce the thickness of the non-adsorption zone, so that the part of the second step plate 112 near the connecting plate 130 can be coplanar with the upper surface of the connecting plate 130.

[0078] like Figure 4As shown, the connecting plate 130 may include a connecting seat 131 and a connecting plate main body 132. A first strip-shaped hole 1311 is provided in the connecting seat 131, and a second strip-shaped hole 1321 is provided in the connecting plate main body 132, facing the side connector 150. The connecting seat 131 protrudes from the connecting plate main body 132. In this embodiment, the connecting seat 131 is connected to the side connector 150, and the side of the connecting seat 131 facing the side connector 150 protrudes from the connecting plate main body 132, which allows the height of the connecting plate main body 132 to be raised to facilitate the connection between the first step plate 111 and the connecting plate main body 132. A clearance groove 1323 may be provided in a portion of the connecting plate main body 132 to avoid other components of the equipment.

[0079] like Figure 6 As shown, the side connector 150 is provided with a limiting groove 151, and the bottom wall of the limiting groove 151 is provided with a third fastening hole 152. The second adsorption part 120 is provided with a mounting hole 124. The end of the second adsorption part 120 is fitted into the limiting groove 151, and the fastener that fixes the second adsorption part 120 passes through the mounting hole 124 and is fastened to the third fastening hole 152. The limiting groove 151 can position the second adsorption part 120, so that after the end of the second adsorption part 120 is fitted into the limiting groove 151, the mounting hole 124 and the third fastening hole 152 can be easily aligned, facilitating the insertion of the fastener. Moreover, the width of the limiting groove 151 can be designed to be greater than the width of other parts of the side connector 150, thereby improving the support effect on the second adsorption part 120.

[0080] The limiting slot 151 is located in the middle region of the side connector 150. One end of the limiting slot 151 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 155 and a mounting hole 154. A pin passes through the positioning hole 155 to position the side connector 150 on the adsorption body, and a fastener passes through the mounting hole 154 to lock the side connector 150 onto the adsorption body. A first fastening hole 153 is provided in the second mounting area to fix the connecting plate 130 to the second mounting area.

[0081] Those skilled in the art will understand that the level of the second adsorption section 120 will affect the level of the adsorbed product to be tested 500, which will also affect the detection quality of the product to be tested 500. Therefore, the level of the product to be tested 500 can be adjusted by adjusting the level of the second adsorption section 120.

[0082] like Figure 5As shown, the second adsorption part 120 is provided with multiple third adjustment holes 125. A third adjustment screw can be threaded into the corresponding third adjustment hole 125 as needed, with the end of the third adjustment screw abutting against the side connector 150. When the levelness of the second adsorption part 120 exceeds a threshold range, the fastener on the lower side (i.e., the fastener used to fix the second adsorption part 120 and the side connector 150; 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 120, thereby adjusting the levelness until it meets the design requirements.

[0083] like Figure 1 As shown in a specific embodiment of this application, the adsorption body may include an adsorption body 160 and a support plate 140 disposed on the upper side of the adsorption body 160. A suction cup 161 is disposed on the adsorption body 160, and a suction cup hole is formed on the support plate 140, into which the suction cup 161 extends. Since the suction cup 161 cannot guarantee the flatness of the product 500 to be tested, especially when the product 500 is a flexible screen, if only the suction cup 161 is used to support the flexible screen, the flatness of the flexible screen cannot be guaranteed. In this embodiment, a support plate 140 is disposed on the upper side of the adsorption body 160. By supporting the product 500 to be tested through the support plate 140, the flatness of the product 500 to be tested can be guaranteed. The support plate 140 can be used to support the display portion of the product 500 to be tested. Furthermore, the suction cup hole on the support plate 140 allows the suction force of the suction cup 161 to act on the product 500 to be tested, thus adsorbing and fixing the product 500 to be tested.

[0084] The levelness of the support plate 140 will affect the levelness of the adsorbed product 500 to be tested, and thus the testing quality of the product 500. Therefore, the levelness of the product 500 to be tested can be adjusted by adjusting the levelness of the support plate 140. In this embodiment, the support plate 140 is provided with a plurality of fourth adjustment holes 141, and a fourth adjustment screw is threaded into the corresponding fourth adjustment hole 141, with the end of the fourth adjustment screw abutting against the adsorption body 160.

[0085] When the level of the support plate 140 exceeds the threshold range, the fastener on the lower side (i.e. the fastener used to fix the support plate 140 and the adsorption body 160; 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 140, thereby adjusting the level until it meets the design requirements.

[0086] like Figure 5As shown, the second adsorption part 120 is provided with a notch groove 123, which, together with the gap between the first adsorption part 110 and the second adsorption part 120, forms the detection hollow area 170. In this embodiment, by providing the notch groove 123 in the detection hollow area, the area of ​​the detection hollow area 170 is expanded, and the notch groove 123 can correspond to the IC area of ​​the product 500 to be tested. Moreover, second adsorption holes 121 are provided around the notch groove 123, thereby increasing the fixation effect on the IC area (the three sides of the IC area are all adsorbed and fixed by the second adsorption holes 121).

[0087] Furthermore, a thinning region 122 is provided on the lower side of the second adsorption part 120, and a notch groove 123 is disposed in the thinning region 122.
