Description

technical field

The utility model relates to the technical field of LED spectrometers, in particular to a suction and transfer device for an SMD LED patch spectrometer.

Background technique

SMD LED is a new type of surface-mounted semiconductor light-emitting device, which has the advantages of small size, large scattering angle, good uniformity of light emission, and high reliability. Its light-emitting colors include various colors including white light. Therefore, it is widely used in various electronic products such as display screens, LCD panel backlights, decorative lighting, and general lighting.

Because the LED packaging must be processed by color separation and light separation before leaving the factory, the LEDs are divided into many bins and categories according to parameters such as wavelength, brightness and operating voltage, and then the LEDs are automatically divided into different Bin tubes according to the set test standards.

LED spectrometers in the prior art include LED in-line spectrometers, SMD (surface mount device) LED patch spectrometers, high-power LED spectrometers, etc. SMD LED patch spectrometer is a special equipment for online classification of SMD LEDs. Its structure mainly includes: high-speed optical spectrometer, electrical parameter measuring instrument and mechanical transmission system. Specifically, its mechanical transmission system mainly includes vibration feeding, suction transfer, chip positioning, chip testing, chip steering, material distribution mechanism, material receiving mechanism, etc.

In the vibration feeding process, the hexagonal LED devices vibrate and move through the circular orbit of the vibrating plate, and after being arranged in two directions, they vibrate through the linear orbit and are sent to the feeding position. The function of the suction and transfer device is to use the vacuum nozzle to suck up the prepared LED device at the front end of the linear track of the vibrating plate and transfer it to the turntable mechanism. There are two requirements for the suction and transfer device: one is the fast action speed. The current mainstream LED spectrometer has a speed of more than 20KUPH, which means that more than 6 chips must be transferred per second, and each round-trip motion cycle of each transfer cannot exceed 0.15 seconds. ; Second, the action must be accurate, including the accurate position of the two endpoints, and the route is accurate at the same time; the third is stable action, no interference during the transfer process, and no material drop of the LED device.

The suction and transfer device in the prior art has the following problems: first, the transfer speed is fast and the air resistance is large, and the LED device is easy to fall off from the suction nozzle during the transfer process, resulting in transfer failure and affecting the overall speed; To extract the LED device from the outlet of the vibrating feeding tray, there is a relatively large stroke. In this stroke, the LED device may rub against the side of the vibrating feeding tray and cause the material to drop; the third is to put the LED device into the When turning the suction nozzle on the turntable, it is easy to rub the side of the suction nozzle on the turntable and cause the material to drop, or it cannot be placed stably, which affects the progress of the subsequent process.

The material suction and transfer device in the above prior art is prone to material drop due to the three reasons analyzed above, which interrupts the working rhythm of the LED spectrometer, thus affecting the speed of the whole machine.
