Embodiment Construction
[0027] refer to figure 1 — Figure 4 , the LED high-speed spectroscopic testing device is composed of a feed mechanism and a test mechanism controlled by a controller. In the feed mechanism, the LEDs can be automatically sorted according to the set positive and negative directions and the circular vibrating discs 2 that are sent out one by one are commercially available. Products, such as the LED vibrating plate produced by Dongguan Changan Jianjia Automation Equipment Factory, have a discharge quantity of 90-160 per minute. The circular vibrating plate 2 is connected with the bar vibrator 1, so that the LED output from the circular vibrating plate enters the straight groove 131 of the bar vibrator body in turn; the bar vibrator body 13 and the slide table 11 are respectively provided with LED pins Insert and run the straight groove, the other end of the straight groove 131 of the bar vibrator body is connected with the upper end of the straight groove 111 of the slide table,...

The invention belongs to the testing technology of luminescent tubes, and particularly provides an LED high-speed light splitting test device. The LED high-speed light splitting test device comprises a feeding mechanism controlled by a controller as well as a testing mechanism, wherein the feeding mechanism comprises a round vibration disc which can automatically rank LEDs in set anode and cathode directions and send out the LEDs one by one; the round vibration disc is connected with a strip-shaped vibrator which is connected with a sliding table; the sliding table is connected with an LED seat stand; an integrating sphere is mounted on the left side of the table-board of the LED seat stand, and a first probe connected with a photoelectric detector and a second probe connected with an optical spectrograph are connected with the integrating sphere respectively; and a right-angle turning rod connected with a motor shaft of a first motor mounted in the right front of the sliding table can shift LED pins to turn over when operating circumferentially, so that the LED pins can be contacted with spring contacts with testing voltage instantaneously. According to the LED high-speed light splitting test device, the testing efficiency is remarkably improved, the automation of the detection process is achieved, the sorting collection based on a testing result is achieved, the structure is simple, and the cost control of mass production is facilitated.
Description
technical field [0001] The invention relates to LED (light emitting diode) testing technology, in particular to an LED (light emitting diode) spectroscopic testing device which improves testing efficiency. Background technique [0002] After the packaging is completed, LEDs need to be tested for optical characteristics, such as testing and sorting for indicators such as light intensity, wavelength, wavelength width, color purity, and color temperature. Due to the huge quantity of LED mass production, it would be labor-intensive and time-consuming to test one by one, and the proportion of cost is too high for enterprises to bear. In the prior art, the LED spectroscopic test is mainly performed by manual sampling with an optical measuring instrument, but in fact, mass-produced LEDs have a certain degree of optical dispersion. If 100% testing and sorting are not carried out, the user's use effect will be directly affected. . In response to this problem, some research results ...
