Embodiment 1

[0041] This embodiment provides a foreign object detection and positioning device, such as Figure 1 to Figure 3 As shown, it includes a power supply, a laser light bar 2 , a first detection sheet 3 , and a second detection sheet 4 .

[0042] Wherein, the laser light bar 2 is provided with a plurality of laser lamps 21, and the negative pole of the laser light bar 2 is electrically connected with the cathode of the power supply through a wire 6, so that the negative pole of each laser light 21 on the laser light bar 2 is connected to the power supply. The cathode electrical connection.

[0043] In order to enable the first detection piece 3 to detect and locate the position of the foreign matter more accurately, the lower end of the first detection piece 3 needs to be set as close as possible to the substrate to be tested. Of course, in order to ensure that no damage is caused to the surface of the substrate to be tested, the first detection The lower end of the piece 3 still n...

Embodiment 2

[0061] This embodiment provides a coating device, including a mounting frame, a nozzle 1, a drive control system, and the foreign object detection and positioning device provided in the above embodiments.

[0062] Wherein, the foreign object detection and positioning device and the nozzle 1 are installed on the mounting frame, and the foreign object detection and positioning device is electrically connected with the drive control system. The control system controls the installation frame to stop moving.

[0063] A sensor is connected to each striker 5, and each sensor is electrically connected to the drive control system. When the sensor senses the position change of the striker 5, it transmits a signal to the drive control system, so that the drive control system controls the mounting frame to stop moving.

[0064] The drive control system is also connected with a cleaning unit, which is used to remove foreign matter adhered to the first detection sheet 3 .

Abstract

The invention provides a foreign matter detection and positioning device. The foreign matter detection and positioning device comprise a laser lamp strip, a first detection piece and second conductivebodies, wherein a plurality of laser lamps are arranged on the laser lamp strip, the laser lamp strip is used for being electrically connected with one end of a power supply; a plurality of first conductive bodies are arranged on the first detection piece in a side-by-side manner; the second conductive body is provided with more than one, each second conductive body is at least corresponding to one of the first conductive bodies, a gap is formed between the first conductive bodies and the second conductive bodies, and the first conductive bodies or the second conductive bodies is correspondingly connected with a laser lamp; and when the first detection piece is deformed by the collision of the foreign matter, the first conductive body at the corresponding position touches the corresponding second conductive body, so that the power supply, the first conductive bodies, the second conductive bodies and the corresponding laser lamps are in communication to form a closed loop, and the position of the foreign matter can be positioned more accurately.

Description

technical field [0001] The invention relates to the technical field of coating technology, in particular to a foreign matter detection and positioning device and a coating device. Background technique [0002] A very important process in the manufacturing process of liquid crystal panels is coating photoresist, and when coating photoresist, metal coating nozzles are used, which move on the glass substrate while spraying photoresist, To achieve the effect of uniform coating of photoresist, the metal coating nozzle is a very precise device, after being scratched by foreign matter such as glass debris, it will cause uneven coating of photoresist, and repairing the coating nozzle is expensive, and It will cause scratches on the underlying film layer and graphics due to interference with the Bar adhesion Particle movement. Therefore, it is necessary to install a foreign matter detection device in front of the coating nozzle. [0003] The existing foreign matter detection device...
