[0002] During the inspection of OLED display panels, they need to be adsorbed onto an adsorption platform to maintain a stable state for effective inspection. In existing technologies, the OLED display panel requires a set of rotating cylinders to rotate a positioning block 180° for positioning during adsorption. However, inaccurate placement during adsorption leads to repeated adjustments and constant rotation of the positioning block, resulting in cumbersome debugging procedures and low inspection efficiency. Furthermore, the existing rotating positioning cylinder assembly design is complex, hindering manufacturing and increasing costs. Utility Model Content

[0029] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0030] Please refer to the following: Figure 1 and Figure 2 This embodiment provides a vacuum suction cup device 10, which can be applied to the detection of display panels 11, such as the detection of OLED display panels. Furthermore, this embodiment also provides a display panel testing fixture, which employs the aforementioned vacuum suction cup device 10. The vacuum suction cup device 10 and display panel testing fixture provided in this embodiment can improve the problems of high difficulty and high cost in OLED display panel positioning in the prior art.

[0031] The vacuum suction cup device 10 includes a suction body 100 and a positioning component 200. The suction body 100 is used to suction the display panel 11, and has a placement plane for placing the display panel 11. When the display panel 11 is suctioned to the suction body 100, the display panel 11 is attached to the placement plane, ensuring the flatness of the display panel 11, which is beneficial for the testing operation. The positioning component 200 includes a slide rail 210, a first positioning member 220 and a second positioning member 230. The first positioning member 220 is slidably connected to the slide rail 210, and the second positioning member 230 is slidably connected to the first positioning member 220. Both the first positioning member 220 and the second positioning member 230 are located on the placement plane and are used to hold different sides of the display panel 11.

[0032] As described above, in this vacuum suction cup device 10, after the adsorption body 100 adsorbs the display panel 11, it can abut against different sides of the display panel 11 by moving the first positioning member 220 and the second positioning member 230, thus providing a positioning function for the display panel 11. Since the first positioning member 220 and the second positioning member 230 can move on the placement plane to achieve positioning of the display panel 11, large-scale flipping and moving are not required, making operation simple and positioning accurate, reducing the difficulty of ceiling installation. Furthermore, compared to the existing flipping cylinder assembly, the slide rail 210, the first positioning member 220, and the second positioning member 230 in this positioning component 200 are easier and cheaper to manufacture. Therefore, the vacuum suction cup device 10 provided by this utility model can improve the problems of high difficulty and high cost in positioning OLED display panels in the prior art.

[0033] It should be noted that during the testing of the display panel 11, the display panel 11 can be placed on the placement surface first, and then adsorbed by the adsorption body 100. After the display panel 11 is adsorbed, the first positioning member 220 can slide relative to the slide rail 210 to support the side of the display panel 11, and the second positioning member 230 can move relative to the first positioning member 220 to support the other side of the display panel 11. This support from different directions ensures the stability of the display panel 11 and guarantees that its position does not change during the testing process. It is worth noting that if the display panel 11 is not placed correctly, the first positioning member 220 and the second positioning member 230 can be moved away from the display panel 11 with only slight operation from the operator, facilitating the adjustment of the position of the display panel 11. The relatively simple and convenient movement of the first positioning member 220 and the second positioning member 230 can improve the problem of high positioning difficulty caused by frequent flipping of the positioning member in the prior art.

[0034] In this embodiment, the adsorption body 100 includes a base 110 and a microporous ceramic component 120. The base 110 has a cavity 111 and is used to connect a negative pressure device to create negative pressure within the cavity 111. The microporous ceramic component 120 is disposed inside the cavity 111 and has multiple uniformly arranged through holes communicating with the cavity 111. A placement plane is formed on the side of the microporous ceramic component 120 away from the base 110, and the through holes form openings on the placement plane. Compared to adsorption components made of metal materials in the prior art, the microporous ceramic component 120, made of ceramic, does not require antistatic treatment. Furthermore, it has a high melting point, high hardness, and is wear-resistant, making its surface less prone to wear. It also has the advantage of being finely and uniformly manufactured using a porous process, with densely packed pores similar to a sponge, making pore clogging less likely. Therefore, compared to adsorption components made of metal materials in the prior art, this adsorption body 100 further reduces manufacturing costs and difficulty, and also reduces the difficulty of subsequent maintenance.

[0035] Optionally, the adsorption body 100 also includes a sealing ring 130, which is disposed between the microporous ceramic component 120 and the base 110. The sealing ring 130 can seal the gap between the microporous ceramic component 120 and the base 110 to prevent air leakage.

[0036] Furthermore, in this embodiment, the adsorption body 100 also includes a transparent element 140 and an imaging device; a receiving groove 141 is provided on the base 110, and the receiving groove 141 is spaced apart from the cavity 111; the imaging device is disposed inside the receiving groove 141, and the transparent element 140 is embedded in the receiving groove 141 to cover the imaging device, which is used to photograph the connection lines of the display panel 11. When the display panel 11 is placed on the placement plane, the connection lines and flexible lines of the display panel 11 can be aligned with the transparent element 140 to facilitate the imaging device to photograph the connection lines, and then the image information acquired by the photograph is used to determine whether the connection lines and flexible lines of the display panel 11 overlap.

[0037] Alternatively, the transparent part 140 can be made of high-temperature resistant glass, and the shooting device can be a digital camera, etc.

[0038] In this embodiment, the slide rail 210 extends along a first direction, the first positioning member 220 extends along a second direction, and the second positioning member 230 extends along the first direction, with the first and second directions forming an angle. Optionally, the first and second directions are perpendicular. This allows the first and second positioning members 220 and 230 to abut against the display panel 11 from two adjacent sides, ensuring they are fully in contact with the display panel 11 for stable support. It also reduces the space occupied by the first and second positioning members 220 and 230, preventing them from obstructing the testing process. Figure 1 Arrow B in the middle indicates the first direction, and arrow A indicates the second direction.

[0039] Furthermore, the slide rail 210 is located on the side of the adsorption body 100, which can prevent the slide rail 210 from obstructing the testing operation. Additionally, the positioning assembly 200 also includes a protective member 240, which is connected to the side of the adsorption body 100 and covers the side of the slide rail 210 away from the adsorption body 100. This protective member 240 provides protection for the slide rail 210.

[0040] Furthermore, there is a gap between the protective member 240 and the slide rail 210. The first positioning member 220 includes a sliding part 201 and a positioning part 202. The sliding part 201 is slidably connected to the slide rail 210 and is located between the slide rail 210 and the protective member 240. The positioning part 202 is connected to the sliding part 201 and is disposed on the placement plane. In other words, the protective member 240 can not only provide protection for the slide rail 210, but also for the sliding part 201, thereby providing protection for the connection between the sliding part 201 and the slide rail 210, ensuring the stability of the sliding connection between the sliding part 201 and the slide rail 210.

[0041] In this embodiment, the vacuum suction cup device 10 further includes a first knob 221 and a second knob 231. The first knob 221 passes through the protective member 240 and is connected to the first positioning member 220. The first knob 221 is used to lock the first positioning member 220 to the slide rail 210 when screwed in, and to release the first positioning member 220 when screwed out. The second knob 231 is connected to the second positioning member 230. The second knob 231 is used to lock the second positioning member 230 to the first positioning member 220 when screwed in, and to release the second positioning member 230 when screwed out. When the first positioning member 220 moves to a suitable position to support the display panel 11, the first positioning member 220 and the slide rail 210 can be fixed by screwing in the first knob 221 to prevent the first positioning member 220 from shifting position during testing, thus ensuring the stability of the display panel 11. Similarly, when the second positioning member 230 moves to a suitable position to support the display panel 11, the first positioning member 220 and the second positioning member 230 can be fixed by screwing in the second knob 231 to prevent the second positioning member 230 from shifting position during the test, thus ensuring the stability of the display panel 11.

[0042] In order to facilitate the first knob 221 to pass through the protective member 240 and connect to the first positioning member 220, the protective member 240 is provided with a slide groove 241 extending in the first direction, and the first knob 221 can pass through the slide groove 241 and connect to the first positioning member 220.

[0043] Of course, after the test is completed, the first knob 221 and the second knob 231 can be turned out to release the first positioning member 220 and the second positioning member 230, so as to allow the first positioning member 220 and the second positioning member 230 to move freely and release the display panel 11.

[0044] To avoid damaging the display panel 11 by pressure, the first positioning member 220 may optionally be provided with a first elastic member 222 for supporting the display panel 11; and / or, the second positioning member 230 may be provided with a second elastic member 232 for supporting the display panel 11. "And / or" means that only the first elastic member 222 or only the second elastic member 232 may be provided; or both the first elastic member 222 and the second elastic member 232 may be provided.

[0045] It is worth noting that, generally, the main body of the first positioning member 220 is at a certain distance from the placement plane, while the first elastic member 222 can contact the placement plane; similarly, the main body of the second positioning member 230 is at a certain distance from the placement plane, while the second elastic member 232 can contact the placement plane.

[0046] In this embodiment, slide rails 210 are provided on two opposite sides of the base 110, and the first positioning member 220 has two sliding portions 201. The two ends of the positioning portion 202 are respectively connected to the two sliding portions 201, and the positioning portion 202 spans the adsorption body 100. Similarly, protective members 240 are provided at both slide rails 210. It should be understood that in some other embodiments, only one slide rail 210 may be provided.

[0047] In summary, in the vacuum suction cup device 10 and display panel testing fixture provided in this application embodiment, after the adsorption body 100 adsorbs the display panel 11, it can abut against different sides of the display panel 11 by moving the first positioning member 220 and the second positioning member 230, thus providing a positioning function for the display panel 11. Since the first positioning member 220 and the second positioning member 230 can move on the placement plane to achieve positioning of the display panel 11, large-scale flipping and moving are not required, making operation simple and positioning accurate, reducing the difficulty of ceiling installation. Furthermore, compared to the existing flipping cylinder assembly, the slide rail 210, the first positioning member 220, and the second positioning member 230 in this positioning component 200 are easier and cheaper to manufacture. Therefore, the vacuum suction cup device 10 provided by this utility model can improve the problem of high positioning difficulty and high cost of OLED display panels in the prior art. Furthermore, compared to the metal adsorption components used in existing technologies, the microporous ceramic component 120, made of ceramic, does not require anti-static treatment. It also boasts a high melting point, high hardness, and abrasion resistance, making its surface less prone to wear. Simultaneously, its porous manufacturing process results in a finely uniform texture, with densely packed pores resembling a sponge, reducing the likelihood of pore blockage. Therefore, compared to metal adsorption components in existing technologies, this adsorption body 100 further reduces manufacturing costs and complexity, as well as subsequent maintenance difficulties. Moreover, the inclusion of the first elastic element 222 and the second elastic element 232 prevents the first positioning element 220 and the second positioning element 230 from causing pressure damage to the display panel 11, ensuring the safety of the display panel 11 during testing.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
