Embodiment 1

[0089] Such as figure 1As shown, the liquid crystal screen detection and assembly device includes a fixing device, a liquid crystal screen detection device and a liquid crystal screen assembly device. The fixing device is used to support and fix the liquid crystal screen, the liquid crystal screen detection device is arranged under the fixing device, and the liquid crystal screen detection and assembly device is arranged above the fixing device.

[0090] The fixing device is a support plate 120 for fixing the liquid crystal screen 130 . The upper surface 121 of the support plate 120 is used for fixing the liquid crystal screen 130 . There is a movable signal transmitting device below. The signal transmitting device is used to transmit a signal to the liquid crystal screen 130, and according to the response of the liquid crystal screen 130 to the signal, it can be judged whether the performance of the liquid crystal screen 130 is normal. In the example shown in the figure, t...

Embodiment 2

[0113] Such as Figure 18As shown, the difference between this embodiment and Embodiment 1 is that the air cylinder 190 is used as the first driving device instead of the asynchronous motor 170 in Embodiment 1. The air cylinder 190 is mounted on the lower surface 122 of the support plate 120 . Cylinder 190 is a two-way motion cylinder. The air cylinder 190 includes a cylinder body 191 and a piston rod 192 . The piston rod 192 is telescopically disposed on the cylinder body 191 . The end of the piston rod 192 is connected with the first slider 152 . By adopting the cylinder 190, the present embodiment does not need to use the transmission belt 173 and the driving wheel 172, the supporting wheel 174 and the tensioning wheel 175 matched with the transmission belt 173. The air cylinder 190 communicates with an air supply device (not shown in the figure) through an air supply pipeline, and the air supply device provides an air source. A solenoid valve is set on the gas supply ...

Embodiment 3

[0116] Such as Figure 19 As shown, the difference between this embodiment and Embodiment 1 is that the asynchronous motor 170 , the first guide rail 151 and the first slider 152 in Embodiment 1 are replaced by linear motors. The linear motor includes coil windings 196 and permanent magnet bars 197 . Permanent magnet bars 197 are mounted on the lower surface 122 of the support plate 120 . The coil winding 196 is set on the permanent magnet bar 197 and can move along the permanent magnet bar 197 . Base 160 is mounted on coil winding 196 . By adopting a linear motor, the present embodiment does not need to use an asynchronous motor 170, a transmission belt 173, and a driving wheel 172 matched with the transmission belt 173, a support wheel 174, and a tensioning wheel 175, and the first guide rail 151 and the first slide block 152 are not required. .

[0117] The rest of the structure of this embodiment is the same as that of Embodiment 1.

[0118] The coil winding 196 can b...

Abstract

The invention discloses a liquid crystal display screen detecting and assembling device. The liquid crystal display screen detecting and assembling device is characterized by comprising a fixing device, a liquid crystal display screen detecting device and a liquid crystal display screen detecting and assembling device body, wherein the liquid crystal display screen detecting device is arranged below the fixing device, and the liquid crystal display screen detecting and assembling device body is arranged above the fixing device. The liquid crystal display screen detecting and assembling device can be used for detecting the performance of the front face of a liquid crystal display screen, pasting a label to the back face of the liquid crystal display screen and pressing a circuit board in an attaching mode to enable the circuit board to be tightly attached to the liquid crystal display screen; detection, pasting of the label and pressing attachment of the circuit board can be conducted at the same time, in this way, the production time of the liquid crystal display screen is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a liquid crystal screen detection and assembly device, in particular to a touch screen detection and assembly device. Background technique [0002] Liquid crystal screens, referred to as liquid crystal screens, especially touch screens, are more and more widely used in electronic products. The touch screen may have quality problems during the production process. In order to avoid using problematic touch screens to produce mobile phones, tablet computers and other products, it is necessary to test the quality of touch screens. One of the electromagnetic touch screens, referred to as the electromagnetic screen, is equipped with an electromagnetic sensing module to control mobile phones and tablet computers by using electromagnetic waves directed at the screen. One of the detection methods for the electromagnetic screen is to first connect the electromagnetic screen to the power supply and communication connection, and the inspe...
