Technical Field

[0002] TP, or Touch Panel, is a human-computer interaction device that enables interactive operations with computers by directly touching the images or text on the screen. It greatly simplifies the operation of traditional keyboards and mice, making human-computer interaction more intuitive and convenient; the basic working principle of the touch screen relies on sensor technology. The sensor is installed in front of the screen to detect the position of the user's touch. When the user touches the screen, the sensor receives the touch signal, converts it into the touch point coordinates, and then sends it to the computer for processing. In this way, the computer can execute the corresponding instructions according to the user's touch operation.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] As described in the background technology, the touch screen needs to be bonded with the lens and the glass during the production process, but bubbles will be generated after the lens and the glass are bonded. This defective part needs to be picked out in advance to avoid difficulty in removing bubbles after curing. Usually, high-pressure baking is used to remove the bubbles. In the existing technology, manual inspection is still required after processing, which is inefficient and prone to errors.

[0031] In order to solve this technical problem, the utility model provides a device capable of identifying bad TP bubbles, which is applied to the identification of bubbles at the joining place of LENS and GLASS.

[0032] Specifically, please refer to Figure 1-Figure 5 , the devices that can identify TP bubble defects specifically include:

[0033] The frame 1 has a crossbeam 2 fixedly mounted on the top thereof, a detection unit is arranged on the crossbeam 2, and the detection unit includes a support member, a light source transmitter 305 and a light source receiver 304 located below the light source transmitter 305 are arranged on the support member, and the light source receiver 304 is used for receiving light emitted by the light source transmitter 305 to realize detection of the product to be tested.

[0034] The utility model provides a device capable of identifying defective TP bubbles. The utility model provides a light source receiver 304 and a light source transmitter 305. The light source transmitter 305 transmits light to the light source receiver 304, and the light emitted by the light source transmitter 305 is received by the light source receiver 304. When the product to be tested passes between the light source receiver 304 and the light source transmitter 305, if bubbles appear, it will cause light scattering and brightness attenuation, so that the light source receiver 304 determines that a certain receiving position is different, thereby realizing automatic detection and identification, and improving detection and identification efficiency and accuracy.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] The light source transmitter 305 will emit light to the light source receiver 304, and these light rays will pass through the fitting area of ​​LENS and GLASS. If there are no bubbles in the fitting area, the light rays will propagate along a predetermined path. If there are bubbles in the fitting area, the bubbles will have different effects on the light rays. The bubbles may change the propagation path of the light, causing part of the light rays to be scattered or reflected. These scattered or reflected lights will change the characteristics of the light signals received by the receiver. The light source receiver 304 will receive and detect these light signals, and by analyzing the received light signals, it can be determined whether there are bubbles in the fitting area of ​​LENS and GLASS. For example, if the intensity of the received light signal is weakened or the fluctuation increases, it may indicate the presence of bubbles. In addition, by analyzing the scattering or reflection pattern of the light signal, the position and size of the bubbles can be further determined.
