Problems solved by technology

If the concentricity between the LED chip and the lens is large, then the subsequent production of the light-emitting module will produce non-uniform light emission (chromaticity, luminance) between the LED chips during work, and even the lens and other components to be assembled Interference between parts occurs, which will reduce product yield
There is currently no detection scheme for the concentricity between the LED chip and the lens in the prior art, so how to quickly detect the concentricity between the LED chip and the lens during production, so that unqualified products can be quickly discharged to improve product qualification Efficiency and cost reduction, this is just the problem that the inventor will solve

Abstract

The invention discloses an image collection device for detecting the concentricity of an LED chip and a lens. According to the technical scheme, the image collection device comprises a base capable of moving up and down and left and right, and the base is located over an LED chip module and provided with an installation block and an image acquiring mechanism; the installation block is detachably provided with an auxiliary support which comprises a cavity, a light hole located under the image acquiring mechanism is formed in the auxiliary support, a UV illuminating device is arranged in the cavity, and the auxiliary support is located over the LED chip module. According to the device, the technical blank of the lens type luminous module detection field is filled up, the production cost of the production activity for producing lens type luminous modules can be greatly reduced, the product yield rate is increased, and meanwhile the production efficiency is improved.

Description

technical field [0001] The invention relates to an image acquisition device for detecting the concentricity between an LED chip and a lens. Background technique [0002] The general structure of the light-emitting module used in the display usually includes LED chips mounted on the PCB by SMT, and then a lens is added to each LED chip to form the LED chip module. If the concentricity between the LED chip and the lens is large, then the subsequent production of the light-emitting module will produce non-uniform light emission (chromaticity, luminance) between the LED chips during work, and even the lens and other components to be assembled Interference between parts occurs, which reduces product yield. There is currently no detection scheme for the concentricity between the LED chip and the lens in the prior art, so how to quickly detect the concentricity between the LED chip and the lens during production, so that unqualified products can be quickly discharged to improve pr...
