Detailed Implementation

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0023] In an embodiment of this utility model, a wiping device and system for display screen detection are provided.

[0024] Please see Figure 1 and Figure 2 A wiping device for display screen detection includes: a first lifting mechanism, a second lifting mechanism, an alcohol wiping base 131, an alcohol wiping end 132 detachably connected to the alcohol wiping base 131, a dry wiping base 141, and a dry wiping end 142 detachably connected to the dry wiping base 141. The second lifting mechanism is installed on the lifting end of the first lifting mechanism, and both the alcohol wiping base 131 and the dry wiping base 141 are installed on the lifting end of the second lifting mechanism.

[0025] Understandably, the alcohol wiping base 131 and the alcohol wiping tip 132 constitute an alcohol wiping head, while the dry wiping base 141 and the dry wiping tip 142 constitute a dry wiping head. Dry wiping is relative to alcohol wiping. The alcohol wiping head can be connected to an alcohol supply device and transport the alcohol supplied by the alcohol supply connector to the nonwoven fabric 30 corresponding to the alcohol wiping tip 132. The dry wiping head does not supply or transfer liquid to the nonwoven fabric 30 corresponding to the dry wiping head.

[0026] In some embodiments, the alcohol wiping end 132 and the dry wiping end 142 move up and down synchronously.

[0027] In this embodiment, the first lifting mechanism includes a cylinder mounting plate 111, a first cylinder 112 mounted on the cylinder mounting plate 111, a slide rail 113 mounted on the cylinder mounting plate 111, a sliding seat 114 slidably connected to the slide rail 113, and a first lifting plate 115 mounted on the sliding seat 114. The lifting rod of the first cylinder 112 is connected to the sliding seat 114 or the first lifting plate 115. Please refer to the above description. Figure 2 As shown, the lifting rod of the first cylinder 112 is connected to the first lifting plate 115. The first lifting mechanism is used to lift the second lifting mechanism, the alcohol wiping end 132 and the dry wiping end 142, and the two mechanisms rise and fall synchronously.

[0028] Understandably, the sliding seat 114, the first lifting plate 115, and the lifting rod of the first cylinder 112 all serve as the lifting ends of the first lifting mechanism. Here, the second lifting mechanism is installed on the first lifting plate 115 in the lifting end.

[0029] Preferably, the first lifting mechanism further includes a slide reinforcing rib 116, which connects the slide 114 and the first lifting plate 115.

[0030] Specifically, the cylinder mounting plate 111 includes a first mounting plate, a second mounting plate, and a third mounting plate. The second mounting plate is mounted on the first mounting plate, forming an L-shaped mounting plate. The third mounting plate is mounted on the second mounting plate and connected to the first mounting plate, reinforcing the L-shaped mounting plate. Here, the first and third mounting plates are perpendicular to the horizontal plane, and the second mounting plate is parallel to the horizontal plane. The first cylinder 112 is mounted on the second mounting plate. The slide rail 113 is longitudinally arranged and perpendicular to the horizontal plane. The slide rail 113 is mounted on the second mounting plate. The sliding seat 114 is slidably connected to the slide rail 113. It can be understood that the sliding seat 114 includes a slider slidably connected to the slide rail 113 and a mounting base plate fixedly connected to the slider. The mounting base plate is connected to the first lifting plate 115. The mounting base plate is longitudinally arranged, and the first lifting plate 115 is transversely arranged.

[0031] In this embodiment, the second lifting mechanism includes a second cylinder 121 and a lifting guide assembly. The second cylinder 121 is mounted on the first lifting plate 115, and the lifting guide assembly is disposed on the first mounting plate. The lifting guide assembly connects the alcohol wiping base 131 and the dry wiping base 141, and the lifting rod of the second cylinder 121 connects the alcohol wiping base 131 and the dry wiping base 141. The lifting rod of the second cylinder 121 serves as the lifting end of the second cylinder 121.

[0032] Understandably, the second cylinder 121 is mounted on the first mounting plate via the second cylinder mounting plate 122, the second cylinder mounting plate 122 is fixedly mounted on the first mounting plate, the second cylinder 121 is located on the first mounting plate, and is connected to the second cylinder mounting plate 122.

[0033] In some embodiments, the lifting guide assembly connects the alcohol wiping base 131 and the dry wiping base 141 to achieve synchronous raising and lowering of the alcohol wiping head and the dry wiping head. The second cylinder 121 and the lifting guide assembly work together to raise and lower the alcohol wiping end 132 and the dry wiping end 142.

[0034] In other embodiments, there are two second cylinders 121, one connected to the alcohol wiping base 131 and the other connected to the dry wiping base 141. Correspondingly, the lifting guide assembly includes a first lifting guide rod 123 and a second lifting guide rod 124 disposed on the first mounting plate. The first lifting guide rod 123 is fixedly connected to the alcohol wiping base 131, and the second lifting guide rod 124 is fixedly connected to the dry wiping base 141, meaning the lifting of the alcohol wiping head and the dry wiping head can be controlled separately. Furthermore, both the first lifting guide rod 123 and the second lifting guide rod 124 are mounted on the first mounting plate via linear bearings 125.

[0035] Further, in one embodiment, the lifting guide assembly includes a spring, a lifting guide rod, and a linear bearing 125. The linear bearing 125 is mounted on a first mounting plate, and the upper end face of the linear bearing 125 is fixedly connected to a first plate. One end of the spring is connected to the first plate, and the other end is connected to the lifting guide rod (first lifting guide rod 123 or second lifting guide rod 124). The spring is partially or entirely located in the linear bearing 125, and the lifting guide rod is partially located in the linear bearing 125. When the lifting rod of the second cylinder 121 extends, the spring is stretched, and the extension of the lifting rod of the second cylinder 121 allows the alcohol wiping end 132 and the dry wiping end 142 to contact the lint-free cloth 30 for wiping the display screen. When it is necessary for the alcohol wiping end 132 and the dry wiping end 142 to move away from the lint-free cloth 30, the restoring force of the spring facilitates or is used for the reset of the corresponding lifting guide rod (first lifting guide rod 123 or second lifting guide rod 124).

[0036] Here, the second cylinder 121 uses a floating joint to protect the cylinder and ensure smooth operation.

[0037] Preferred, such as Figure 3 The alcohol wipe head has a flow channel inside, such as... Figure 3 As shown by the dotted line, the alcohol inlet end of the flow channel serves as an alcohol supply connector mounting hole for connecting the alcohol supply mechanism. Here, the structure and installation position of the alcohol supply mechanism are not limited. The alcohol outlet end of the flow channel is located at the bottom end of the alcohol wiping end 132 and is used to flow alcohol onto the lint-free cloth 30. This embodiment does not limit the specific design of the flow channel.

[0038] The alcohol wiping tip 132 can be connected to the alcohol wiping base 131 via screws. The alcohol wiping base 131 is connected to the telescopic rod of the second cylinder 121 and the first lifting guide rod 123. The alcohol wiping tip 132 and the alcohol wiping base 131 are interconnected through pre-processed grooves (i.e., flow channels), meaning that no additional pipe connections are required; they are connected through the grooves inherent in their own structure. The flow channel includes a first flow channel 1311 and a second flow channel 1321. The first flow channel 1311 is a groove in the alcohol wiping base 131, and the second flow channel 1321 is a groove in the alcohol wiping end 132. The inlet end of the first flow channel 1311 serves as an alcohol supply connector mounting hole for connecting to the alcohol supply mechanism. The outlet end of the first flow channel 1311 connects to the inlet end of the second flow channel 1321, and the outlet end of the second flow channel 1321 serves as the alcohol outflow end of the flow channel. Alcohol flows from the alcohol wiping base 131 into the interior of the alcohol wiping end 132, and then flows from the alcohol outflow end of the flow channel onto the lint-free cloth 30, wetting the lint-free cloth 30. This design facilitates the replacement of the alcohol wiping end 132 without disassembling the alcohol supply pipeline, making the replacement operation simple.

[0039] Correspondingly, the dry wiping end 142 is connected to the dry wiping base 141 by screws, and the dry wiping base 141 is connected to the telescopic rod of the second cylinder 121 and the second lifting guide rod 124.

[0040] In this embodiment, the wiping base is made of aluminum; the wiping tip is made of non-metallic material to prevent scratching the screen.

[0041] Here, the alcohol wiping end 132 and the dry wiping end 142 are arranged side by side, and can usually be at the same height.

[0042] A wiping device for display screen inspection, when wiping, uses non-woven fabric 30. A first lifting mechanism lowers a second lifting mechanism, an alcohol wiping base 131, an alcohol wiping end 132, a dry wiping base 141, and a dry wiping end 142. The second lifting mechanism lowers these components, ensuring they are in contact, before wiping. The cylinder pressure is adjusted by a pressure regulating valve for buffering. After wiping, the second lifting mechanism raises the alcohol wiping base 131, alcohol wiping end 132, dry wiping base 141, and dry wiping end 142. At this point, the non-woven fabric 30 can be replaced. When wiping is needed again, the second lifting mechanism is activated to lower the alcohol wiping end 132 and the dry wiping end 142. When it is necessary to replace the alcohol wiping end 132 and / or the dry wiping end 142, the first lifting mechanism and the second lifting mechanism are activated to raise the alcohol wiping end 132 and the dry wiping end 142, and then the replacement is performed.

[0043] As can be seen from the above detailed description of the specific embodiments of this utility model, compared with the prior art, this utility model improves the wiping effect by simultaneously providing an alcohol wiping end 132 and a dry wiping end 142 to achieve both alcohol wiping and dry wiping, resulting in a cleaner display screen that is beneficial for subsequent display screen testing.

[0044] Furthermore, this utility model has a compact structure, both wiping ends are replaceable, and even further, the alcohol wiping end 132 is easy to replace.

[0045] like Figure 4 The present invention also provides a wiping system for display screen inspection. This wiping system includes a wiping device for display screen inspection as described in any of the above embodiments, and also includes a lint-free cloth support device. The lint-free cloth support device supports the lint-free cloth 30 to allow it to unfold. Through the support of the lint-free cloth 30, both the alcohol wiping end 132 and the dry wiping end 142 can contact the unfolded lint-free cloth 30 on the lint-free cloth support device. It can be understood that this wiping system, using the above-mentioned wiping device, can perform both alcohol wiping and dry wiping, resulting in good wiping effects on the display screen, balancing efficiency and effectiveness.

[0046] The cleanroom cloth support device is a cleanroom cloth support and movement device that can support and move the cleanroom cloth 30. It can move the cleanroom cloth 30 to change the area of ​​the cleanroom cloth 30 that is in contact with the alcohol wiping end 132 and the dry wiping end 142, so that different parts of the cleanroom cloth 30 can contact the wiping device in a certain order, and different parts can be used to wipe the display screen respectively.

[0047] Specifically, the cleanroom wipe support and movement device includes a main mounting plate 21, on which the cylinder mounting plate 111 of the wiping device is mounted. Several support columns 22 are mounted on the main mounting plate 21. Typically, the support columns 22 are located outside the wiping device and are used to support the cleanroom wipe 30. Figure 4 It includes at least four supports 22, two located on the left side of the wiping device and two located on the right side of the wiping device. In some embodiments, the supports 22 are rotatably connected to the main mounting plate 21, and the supports 22 are self-rotating.

[0048] Understandably, the cleanroom wipe support and moving device also includes a pay-off reel, a take-up reel, a pay-off motor mechanism for rotating the pay-off reel, and a take-up motor mechanism for rotating the take-up reel. One end of the cleanroom wipe 30 is wound around the pay-off reel, and the other end is wound around the take-up reel; the support column 22 serves as a tensioning wheel. The pay-off reel, take-up reel, pay-off motor mechanism, and take-up motor mechanism can all be mounted on the main mounting plate 21.

[0049] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a detachable connection or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
