Description

Technical Field

[0001] The invention belongs to the technical field of diode detection devices, and in particular relates to a double-arm rotary light emitting diode detection device. Background Art

[0002] The double-arm rotary light-emitting diode is a special light-emitting diode that may have a rotary structural feature and is widely used in warning lights and other fields. Light-emitting diodes, referred to as LEDs, emit light by releasing energy through the recombination of electrons and holes, and can efficiently convert electrical energy into light energy. Light-emitting diodes are widely used in lighting, flat-panel displays, medical devices and other fields. The double-arm rotary light-emitting diode may be particularly used in occasions that require rotation or dynamic display, such as rotary warning lights, due to its special rotary structure.

[0003] Diode testing is an important part of the quality control system to ensure that electronic products meet the established performance indicators. The stability of diode performance is directly related to the working state of the circuit. Testing can ensure the normal operation of the circuit. Through testing, unqualified diodes can be found and replaced in time to extend the service life of electronic equipment.

[0004] There are many types of diodes. In most cases, the positive and negative long wires (or pins) of the light-emitting diode extend in opposite directions so that the positive and negative poles can be clearly distinguished during connection and the correct current direction can be ensured. Of course, there are also some designs of diodes whose pins may extend in the same direction. For double-arm rotary light-emitting diodes, the long wires connecting the positive and negative poles at both ends are usually in opposite directions to ensure correct connection and normal operation of the diode.

[0005] Referring to the announcement number CN110833994A, a light-emitting diode detection device is characterized in that it includes a column, a support platform, a clamping platform, a lifting plate, a detection head, a detector and a collection box. The cross-sections of the support platform and the clamping platform are both circular. The support platform is installed below the column, the clamping platform is arranged at the upper end surface of the support platform, and a rotating motor is installed on the lower end surface of the support platform. The output shaft of the rotating motor passes through the shaft platform and is connected to the center of the lower end surface of the clamping platform. A plurality of mounting notches are circumferentially arranged at the edge of the clamping platform, and the mounting notches pass through the upper end surface and the lower end surface of the clamping platform. A top plate is provided at the upper end of the column, and a lifting motor is installed on the top plate. The output shaft of the lifting motor is connected to the lifting plate. The detection head is installed on the lifting plate, and the detection head is connected to the lifting plate. The detection head is located directly above any one of the mounting notches. A rejection mechanism is provided on the support platform, and the collection box is arranged directly below the rejection mechanism, and the detector is connected to the rejection mechanism.

[0006] In the process of implementing this application, it was found that the technology has the following problems: in the above patent documents, the fixed detection of diodes is completed on a clamping table. The diodes during detection need to be installed on several mounting notches on the clamping table, and then the clamping table is rotated to perform detection in turn, and unqualified diodes are collected using a collection box; in actual use, since the clamping table is rotating, when a qualified diode is detected, the qualified diode cannot be taken immediately, and it is necessary to wait until the diodes on all the mounting notches are detected and then put them one by one, and due to the clamping of the clamping head, the qualified diode may be stuck on the mounting notch, which is inconvenient for taking the qualified diode, and the new diode to be tested cannot be replaced immediately after the diode is tested, and the detection efficiency is poor.

[0043] The implementation principle of the double-arm rotary light emitting diode detection device of the present application is as follows:

[0044] When using the device, first connect the external power supply. When testing the double-arm rotary light-emitting diode, the double-arm rotary diode can be placed into the through slots 52 in several positioning mechanisms 5 in turn. At this time, the light-emitting diode will fall to the upper surface of the movable plate 59, and then the electric cylinder 2 562 can be started to make the piston rod 2 563 drive the left clamping plate 564 and the left rubber pad 565 to approach one side of the diode at the through slot 52. At the same time, the electric cylinder 3 571 is started to make the piston rod 3 572 drive the right clamping plate 573 and the right rubber pad 574 to approach the other side of the diode at the through slot 52, until the left rubber pad 565 and the right rubber pad 574 fix the diode, and then the diode can be tested using the guide mechanism 3 and the lifting detection mechanism 4; through the cooperation of the above structures, the double-arm rotary light-emitting diode can be stably clamped during detection to prevent the diode from moving during detection and improve detection efficiency.

[0045] When the clamped double-arm rotary light-emitting diode is detected by using the guiding mechanism 3 and the lifting and detecting mechanism 4, the motor 31 can be started to rotate the screw rod 32. At this time, the moving block 33 can move laterally under the rotation of the screw rod 32. The moving moving block 33 will drive the upper end of the guide slide 34 to slide on the inner surface of the limiting slide groove 21 so as to guide the movement of the moving block 33; and the movement of the moving block 33 will also drive the lifting and detecting mechanism 4 to move to the top of different positioning mechanisms 5, so that the lifting and detecting mechanism 4 can detect several double-arm rotary light-emitting diodes clamped in the through groove 52.

[0046] When the lifting detection mechanism 4 moves to the target position, the controller 23 can control the start of the electric cylinder 41 to make the piston rod 42 drive the detection head 43 to move downward until the positive electrode 44 and the negative electrode 45 extend into the through groove 52 and touch the diode, so that the detector 22 can detect the double-arm rotary light-emitting diode to determine whether it is qualified, and feed back the detection data to the controller 23. When the detected diode is an unqualified product, the controller 23 will control the electric cylinder four 581, the electric cylinder two 562 and the electric cylinder three 571 to perform corresponding actions. When the detected diode is a qualified product, the controller 23 will also control the electric cylinder two 562 and the electric cylinder three 571 to perform corresponding actions, so as to collect the unqualified diodes and the qualified diodes separately and improve the detection efficiency.

[0047] After the double-arm rotary light-emitting diodes are inspected by the guide mechanism 3 and the lifting inspection mechanism 4, if unqualified products are encountered, the electric cylinder 581 can be controlled to make the piston rod 582 drive the support plate 583 to move downward into the slide groove 55. At this time, the movable plate 59 will tilt downward without support from below, and then the left clamping assembly 56 and the right clamping assembly 57 will release the clamping of the unqualified diodes. At this time, the unqualified diodes will pass through the through grooves 52 and 14 and fall into the collection mechanism 6 inside the collection chamber 11 so as to be collected in a centralized manner. and when the diode is qualified, the electric cylinder 2 562 is controlled to make the piston rod 2 563 drive the left clamping plate 564 and the left rubber pad 565 to move toward the collecting tank body 561, and the electric cylinder 3 571 is controlled to make the right clamping plate 573 and the right rubber pad 574 brought by the piston rod 3 572 push the qualified diode, so as to push the qualified diode to the collecting tank body 561, so as to facilitate the staff to take the qualified diode, and then facilitate the placement of new diodes to be tested in the through slot 52, thereby improving the detection efficiency.

[0048] On the other hand, when it is necessary to remove unqualified diodes, the handle 13 can be held to allow the sealing plate 12 to drive the slide plate 62 to slide on the inner surface of the U-shaped trough 61 until the slide plate 62 drives the collection box 63 to slide to the outside of the collection chamber 11, so that the staff can centrally process the unqualified diodes inside the collection box 63.
