Description

Spraying device

technical field

The present invention relates to a spraying device, and in particular to a colloid spraying device.

Background technique

At present, the method of forming the fluorescent adhesive layer can be divided into dispensing method and spraying method. The fluorescent glue layer formed by dispensing tends to have uneven thickness and concentration distribution, which affects the color uniformity of the light emitted by the LED. For example, when the blue light emitted by the blue LED chip passes through the thicker part of the yellow fluorescent colloid, yellowish light will be generated. If the fluorescent adhesive layer is formed by spraying, although the disadvantages caused by the above-mentioned dispensing method can be avoided, since the amount of adhesive sprayed by the nozzle cannot be known in real time, it is impossible to adjust the total pressure in the glue bucket immediately. The amount of colloid that is sprayed. Therefore, when the total pressure in the glue tank decreases due to the reduction of the glue, the amount of glue sprayed by the nozzle will be relatively reduced, and the spraying process will not achieve the desired effect. Therefore, how to effectively improve the spraying yield of the spraying method is a technology worth exploring.

Please refer to FIG. 1 , the spraying device 100 of this embodiment includes a receiving tank 110 , a nozzle 120 and a detection unit 130 . A colloid 80 is installed in the containing groove 110 . The nozzle 120 is connected to the receiving tank 110 to spray the glue 80 onto a workpiece 50 .

In this embodiment, the detection unit 130 detects a specification data of the colloid 80 sprayed on the workpiece 50, and the user can monitor the spraying situation of the colloid 80 in real time according to the specification data, which can avoid the problem of inconsistency in the amount of spraying, and then can improve the spraying process. The spraying yield of the device 100. Here, the detection unit 130 is, for example, a weighing device 130A, and the specification data includes the weight of the glue 80 on the workpiece 50 . In other words, in this embodiment, the weighing device 130A detects the weight of the glue 80 sprayed on the workpiece 50 to know the spraying amount of the nozzle 120 .

Specifically, in this embodiment, the spraying device 100 further includes a controller 140 and a regulator 150 . The controller 140 is connected to the detection unit 130 and receives specification data to generate adjustment data. The adjuster 150 is connected to the holding tank 110 and the controller 140 , wherein the adjuster 150 receives adjustment data, and adjusts the spraying amount of the nozzle 120 according to the adjustment data. In this embodiment, after the weighing device 130A detects the weight (specification data) of the colloid 80 on the workpiece 50, the controller 140, such as a computer, receives the aforementioned specification data, and calculates the weight of the workpiece according to the specification data. The thickness of the glue 80 on the 50 can further calculate the spraying amount of the nozzle 120 , and then generate an adjustment data according to the aforementioned spraying amount. After that, the adjuster 150 , such as an actuator, receives the adjustment data and adjusts the spraying amount of the nozzle 120 . In addition, in this embodiment, the spraying device 100 further includes an air pressure unit 160 , such as an air pressure pipeline.

For example, when the thickness of the glue 80 on the workpiece 50 is too thick, the weight measured by the weighing device is relatively heavy, and it can be deduced that the spraying amount of the nozzle 120 is too large. At this time, the adjuster 150 reduces the air pressure of the air pressure unit 160 according to the received adjustment data, so that the spraying amount of the nozzle 120 becomes smaller. Conversely, when the thickness of the glue 80 on the workpiece 50 is too thin, the weight measured by the weighing device is relatively light, and it can be deduced that the spraying amount of the nozzle 120 is too small. At this time, the adjuster 150 can increase the air pressure of the air pressure unit 160 according to the received adjustment data, so that the spraying amount of the nozzle 120 becomes larger. In this way, the spraying device 100 of this embodiment can not only know the spraying amount of the nozzle 120 from the specification data in real time, but also can adjust the spraying amount of the nozzle 120 in real time through the controller 140 and the regulator 150 to stabilize the sprayed amount.
