Manufacturing method of double-color COB light source

Abstract

The invention relates to the technical field of COB light sources, in particular to a manufacturing method of a double-color COB light source, a manufacturing device of the double-color COB light source is used, and the manufacturing device of the double-color COB light source comprises a U-shaped frame, a conveying belt, a fixing base, a supporting unit and a blanking unit. An existing stamping device has the following problems that according to the stamping device, aluminum substrates need to be frequently installed, the aluminum substrates cannot be continuously stamped, and the stamping efficiency of the aluminum substrates is prone to being reduced; according to the punching device, a punch needs to be replaced frequently, the situation that the punch is not installed in place possibly can be caused, and therefore the punching precision of an aluminum substrate is easily affected; intermittent and continuous blanking processing can be carried out on the substrate through the supporting unit and the blanking unit, and the blanking efficiency of the substrate can be improved; blanking machining can be conveniently conducted on substrates of different models through the U-shaped cutter, and the U-shaped cutter can be limited and fixed, so that the situation that the blanking precision of the substrates is affected due to shaking of the U-shaped cutter is avoided.

Description

technical field [0001] The invention relates to the technical field of COB light sources, in particular to a manufacturing method of a two-color COB light source. Background technique [0002] COB light source refers to the high-efficiency integrated surface light source technology that directly attaches the COB chip to the metal substrate. At present, the common COB light sources are mostly two-color COB light sources. Light source packaging and other steps, wherein, when the substrate is fabricated, the substrate needs to be punched into a circle according to processing requirements, and multiple positioning grooves need to be punched out to facilitate the assembly of the COB light source in the later stage. [0003] Substrates can be divided into polymer substrates, ceramic substrates and aluminum substrates according to their materials. In the production process of aluminum substrates, aluminum substrates need to be punched or punched according to customer requirements. ...

AI Technical Summary

Problems solved by technology

[0005] However, the above aluminum substrate stamping device also has the following problems: 1. The above stamping device needs to position the aluminum substrate through positioning nails, so it needs to frequently install the aluminum substrate, the operation is cumbersome, and it cannot continuously punch the aluminum substrate, which is easy to reduce Stamping efficiency for aluminum substrates

[0006] 2. The above stamping device stamps the aluminum substrate only through the punches in the stamping device. If different types of aluminum substrates are stamped, the punches need to be replaced, and frequent replacement of the punches will easily cause the mounting end of the punch to appear. Wear and tear may cause the punch not to be installed in place, which will easily affect the stamping accuracy
