Description

The spectroscopic measurements device

Technical field

The utility model relates to a kind of LED checkout equipment, specifically is the spectroscopic measurements device.

Background technology

Usually LED (light emitting diode) will detect after manufacturing is finished and after user's purchase.At present the detection of LED is carried out on minute optical detector.Concrete detection principle is that a LED to be checked is put on the measured material of spectroscopic measurements device, the luminous point of LED is positioned on the sphere of integrating sphere bottom, then fixed L ED and two haptic elements making two probes on the anchor clamps press LED respectively keep electric connections, and energising at last makes LED luminous and detect; Surveyed the back and from anchor clamps, taken out the LED that measured, in measured material, put into a LED to be checked again, repeated by above step; So go round and begin again.

The defective of above measuring instrument is that tested LED need be positioned on the sphere of integrating sphere and detects, and therefore each clamping anchor clamps can only detect a LED, and not only detection efficiency is low, and is consuming time more, and the single product after can only finishing manufacturing carries out.

On the other hand, the LED in the manufacture process, single LEDs just is fixed on the plate (all arranging dozens of LED on each plate) that is integrated into a piece rectangle on the support after finishing structure dress operation; Though the LED of this moment has related parameter to revise by adjusting; But because the physical dimension of plate big (usually all more than tens centimetres) can't divide optical detector that each LED on the plate is detected with existing LED.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of LED checkout equipment is provided, and this equipment should have detection efficiency height, fireballing characteristics; And can the LED semi-manufacture in the manufacture process be detected, so that the underproof product of some index is in time regulated finishing, be beneficial to improve yield rate.

The utility model has adopted following technical scheme:

The spectroscopic measurements device, comprise frame, track, rack-mounted integrating sphere, can be along orbital motion and at the anchor clamps of the following turnover of integrating sphere; It is characterized in that described integrating sphere is segment shape, the anchor clamps that level was inserted when the breach plane faced measurement vertically downward as incidence surface, the breach plane is detected so that the light that each LED energising is sent all enters integrating sphere greater than the LED locating area on the anchor clamps; And guaranteed the consistance of the LED measurement result absolute accuracy of diverse location.

Be provided with the plane surveying district that receives LED light in the described breach plane.

Use principle of the present utility model is:

When 1, detecting single finished product LED, testing process is still identical with existing mode.

When 2, detecting the integrated plate of LED (semi-manufacture), be the big anchor clamps that can hold the plate location with clamp-replacing in advance.During measurement a plate level to be measured being put into the die of anchor clamps and cover pressing plate makes plate fix; The probe of this moment in die roof pressure (two haptic elements of each LED all have a probe contact to be electrically connected keeping respectively) on the haptic element of LED from bottom to top; After promoting measured material then and making it slip into the bottom location (being the measurement zone that all LED on the anchor clamps to be measured all enter the integrating sphere bottom) of integrating sphere along guide rail, energising makes LED luminous respectively one by one and detect; After having surveyed all LED on the plate, the pulling measured material shifts out its bottom from integrating sphere, (wherein the index of some plate is defective can carry out technical finesse again for plate that taking-up was measured and classification, become specification product after revising data), in measured material, put into a plate to be checked again, undertaken measuring again by above step; So go round and begin again.

The beneficial effects of the utility model are: though tested LED is not positioned on the sphere of integrating sphere, but be dispersed on the sagittal plane of integrating sphere; But the data that actual detected obtains show the testing result error of the two very little (less than the units of number percent); Therefore, the latter's accuracy of detection reaches request for utilization fully.In addition, owing to can directly detect, thereby realized that feasible wherein still have the semi-manufacture of quality index defective to find ahead of time, and can in time revise and become specification product the half-finished quality testing in the manufacture process to the dozens of LED on the plate; Thereby make the yield rate of final products improve greatly, and consuming and then significantly reduction of cost, economic benefit significantly improves; And, because putting into instrument together, the dozens of LED on the same plate goes to measure, not only improved surveying work efficient, also reduced Measuring Time.

Embodiment

As shown in the figure, the spectroscopic measurements device comprises frame 4, track 1 (representing with dot-and-dash line among the figure), rack-mounted integrating sphere 6, can move with the anchor clamps 5 (utilizing track to move horizontally anchor clamps has been prior art) in the following turnover of integrating sphere along track cross level; All parts are installed on the base 2.Described anchor clamps top is shaped on the die 10 that location plate to be measured is used, the shape of this die should adapt with the size of plate to be measured, make plate can put into the groove in the middle of the die, limit the motion of plate, reach the purpose of location by the cell wall around the groove.Vertically locating several probes that are electrically connected with LED 18 in the die, the die both sides are shaped on the claw (comprising stationary jaw 9 and movable jaw 12) that the card clamp block is used respectively.

Shown in Figure 6 is a kind of conventional plate 16, is arranged with 18 LED19 above, and each LED all has two haptic elements 20, and (plate of different size, the quantity of LED are also different; The size respective change of required groove); Because still in manufacture process, thus the haptic element of each LED all in the hollow out position of chip (be that drawing is clear, do not show among the figure), only LED pipe shaft and plate base material have the part adhesion so that LED locatees.After chip was put into groove, two haptic elements of each LED were subjected to the roof pressure contact that a probe 18 makes progress respectively, thereby keep being electrically connected; Can make the electrical connection of probe more reliable after adding a cover pressing plate 11 (shown in Figure 7, be shaped on this pressing plate and the matched hollow out of the shape and structure of described plate position 11-1, make pressing plate only exert pressure, the LED haptic element is then kept contactless state) to LED pipe shaft contact.
