Description

Technical Field

[0001] The utility model relates to the technical field of automatic sorting devices, in particular to an online automatic sorting device for display cover plates. Background Art

[0002] With the development of technology, cover plates of various display devices, such as mobile phones, tablets, and TVs, play an increasingly important role in people's daily lives. The screens of these devices usually use coated cover plates to protect the display surface and enhance the viewing experience. In order to reduce the reflection and glare of external light, an anti-glare film layer is usually applied on the cover plate. However, the traditional anti-glare film coating process has the problem of uneven coating thickness, resulting in color difference or white fog, affecting the appearance and performance of the product.

[0003] In the field of display cover manufacturing, especially in the production process of electronic products such as smart phones, tablet computers, and car displays, the appearance quality of the products is extremely high. After the cover is screen-printed with ink and cured, colorimetry detection is required to ensure that the color and brightness of the ink meet the design specifications. Traditional detection methods usually rely on manual visual inspection or offline detection equipment. These methods are not only inefficient, but also easily affected by subjective factors, resulting in limited accuracy of the test results or missed inspections and misreading. In addition, if unqualified products are not discovered until the subsequent second-layer screen printing or coating process, it will cause higher waste of materials and processing costs, and there will be a risk of claims from customers if they are leaked. Therefore, it is necessary to develop an online, automated colorimetry detection and sorting system to improve efficiency and reduce unnecessary cost losses. Utility Model Content

[0078] A scanning plate 16 for scanning is attached to the bottom of the colorimetry tester 13 .

[0080] Example 3

[0081] The display cover plate online and automatic sorting device provided in Example 1 or 2 is further optimized, such as Figure 1-6 As shown, the connection between the telescopic component 11 and the bracket 21 is also connected with a command sending tube 17, and an information collection unit is embedded in the command sending tube 17;

[0082] The pipe suction ends of the plurality of vacuum suction nozzles 14 are sealedly connected to the air inlet of an external suction pump through a hose 18 .

[0083] The adsorption sleeve 14 and the hose 18 used achieve the connection between the specific pressurized gas and the suction pump to ensure that the generation of air pressure can accurately adsorb the cover plate 27.

[0084] The other end of the telescopic component 11 is installed with an electric telescopic cylinder 19, which controls the telescopic component 11 to telescope linearly. The four gripping rubber sleeves 15 grip the defective display cover plate by suction.

[0085] The electric telescopic cylinder 19 and the gripping rubber sleeve 15 are used to quickly and conveniently combine the telescopic component 11.

[0086] A positioning identifier 28 is also provided at the bottom of the cover plate 27 , and the positioning identifier 28 wirelessly senses positioning through the radiated infrared laser and the command sending tube 17 .

[0087] The positioning identifier 28 and the instruction sending tube 17 used ensure that the specific instructions can be smoothly implemented through the instruction sending tube 17.

[0088] Example 4

[0089] The display cover plate online and automatic sorting device provided in the above embodiments is further optimized, such as Figure 7 As shown, the vacuum suction mechanism 3 includes a vacuum pump 31 connected to the side wall of the end of the hose 18, and a suction fan blade 32 is installed on the top of the vacuum pump 31. Support connecting rods 33 are respectively supported on both sides of the bottom of the suction fan blade 32, and the end side wall of one of the support connecting rods 33 is connected to one end of the hose 18.

[0090] The suction fan blades 32 and the support and drying 33 used determine the air pressure generated by the guide fan.

[0091] A fitting bracket 191 is installed on the back side of the electric telescopic cylinder 19 .

[0092] Ensure that the electric telescopic cylinder 19 can be firmly limited.

[0093] The use process provided by the utility model is as follows: When using it specifically, first step 1: the cover plate 27 is transmitted;

[0094] First, the cover plates 27 that the personnel need to detect are uniformly placed in the area with the corresponding cover plates 27, so that the corresponding toughened pads 23 can increase the support strength of the structure, and the transfer is implemented by using the structure of the corresponding toughened pads 23. Finally, the axial rotation and rolling state of the specific crawler transmission roller 25 will make the detection structure on the surface approach to the surface of the specific cover plate 27. After the approach is completed, the specific cover plate 27 that needs to be detected will automatically move around the position of the crawler roller limit bracket 26. When it moves to the appropriate position;

[0095] When testing is required, when the color of the tested cover plate 27 exceeds the preset range, the control system will instruct the conveyor belt to stop and start the vacuum suction nozzle 14 suction pump;

[0096] Step 2: Transfer the cover plate 27 and classify the defective products;

[0097] The vacuum nozzle 14 is connected to the colorimeter 13 through an electric telescopic cylinder 19 and can be extended downward to the conveyor plane according to control instructions;

[0098] At this time, the vacuum nozzle 14 absorbs the oversized cover plate 27 to shrink the electric telescopic cylinder 19 and transfers it to the defective conveyor belt next to it through the longitudinal conveyor shaft;

[0099] At this time, the defective conveyor belt receives the over-standard cover plate 27 transferred by the vacuum suction nozzle 14, and transports it to the corresponding post for scrapping;

[0100] The specific trigger detection method is: the scanning plate 16 will be with the cover plate 27. If the color abnormality is not triggered, it will be judged as a good product and continue to move to the subsequent process on the main conveyor belt;

[0101] This process allows the control system to adjust the preset parameter range to adapt to the cover plates 27 of different colors and brightness standards and transfer them to another production line for classification. Finished products and defective products can be separated after analysis because of their different color changes.

[0102] In addition, the axial direction of the crawler transmission roller 25 in the technical solution realizes the forward and backward transfer of the position of the upper cover plate 27, and utilizes the sharing effect of the corresponding toughening pad 23 to ensure that the forward-moved cover plate 27 is transferred to the specific brightness value detection mechanism 1 position.

[0103] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
