High-speed visual positioning device and method applied to substrate

Abstract

The invention discloses a high-speed visual positioning device and method applied to a substrate. The high-speed visual positioning device applied to the substrate comprises a frame, a temporary storage area, a positioning area, a transport positioning device, at least two visual devices arranged on the frame and a carrier plate, wherein the transport positioning device is movably arranged on theframe and is used for absorbing and transporting a plurality of substrates; the transport positioning device comprises an I-shaped absorbing head which is used for absorbing the plurality of substrates sequentially; the at least two visual devices correspond to the I-shaped absorbing head and are used for capturing an image of each substrate absorbed by the transport positioning device so as to position the plurality of substrates; and the carrier plate is arranged on the frame.

Description

technical field [0001] The invention relates to a high-speed visual positioning device and method suitable for substrates, in particular to a high-speed, high-precision high-speed visual positioning device and method suitable for strip modules of light-emitting diodes. Background technique [0002] The advantages of light-emitting diodes are: (1) the energy conversion efficiency of light is high, so it saves power; (2) the response time is fast, and it can reach a high flicker frequency; (3) it is more environmentally friendly, there is no harmful substance of mercury, and it is easy to use. recycling and more. In addition, it also has the advantages of resistance to mechanical shocks such as shocks, small size, easy focusing, and wide color gamut. Therefore, "light emitting diodes" are also widely used in various light source fields. [0003] For example, the backlight module of the light source of the display panel can be roughly divided into a direct-type light source o...

Problems solved by technology

[0005] 1. Since there is currently no automatic production equipment for the strip-shaped light bar structure or the substrate, it is all done manually, for example, manually attach the substrate to the carrier, and then print the barcode of the substrate; and then manually Carry out board disassembly; then, manually tape the board again, and then carry out printing / part placement / reflow and other processes

It is obvious that the accuracy of the boards made by the above-mentioned manual method is not good. In addition to the error of manual lamination, the accuracy cannot be effectively controlled due to the bending or offset of the long strip substrate itself. For example, the board is skewed, Not positioned, etc., resulting in poor printing of barcodes or poor printing and placement, etc.

[0006] 2. Bearing in mind 1, because the accuracy cannot be effectively controlled, a large number of personnel must be arranged to carry out various inspection operations, such as product appearance inspection, inspection of LEDs for offset, etc., so labor costs also cause the production unit of LED light bar structure burden

[0007] 3. Moreover, the efficiency of manual pasting operations varies greatly, and it is difficult to control regardless of quality or speed
