[0023] like Figures 1 to 4As shown, the present invention provides a light-emitting diode polarization device, including a diode 1 and a long conveying module 3, the conveying module 3 adopts a multi-stage distribution design, and the conveying module 3 is arranged obliquely, and a discharging component for conveying the diodes 1 one by one to the conveying component is arranged above the lowest conveying module 3, so that the discharging component releases the diodes 1 one by one to the conveying module 3 of the lowest section, and at the same time, the diodes 1 are conveyed upward section by section through the conveying module 3, and detection modules 2 corresponding to each other are arranged above the conveying modules 3 of other sections, and there are at least two detection modules 2, and each detection module 2 includes a conveying pickup Module 4 and conductive detection module 5, all the transmission and picking modules 4 are arranged in a stepped manner from low to high, and baffles 6 are set on the front and rear sides of the transmission module 3 to prevent the diode 1 from falling from the two sides of the transmission module 3, and the distance between the two baffles 6 is slightly larger than the outer diameter of the diode 1 tube head, and the diode 1 is transmitted from bottom to top through the transmission module 3; at the same time, each section of the transmission module 3 is installed by a telescopic traction assembly, so that it can move in the front and rear direction under the action of the telescopic traction assembly; a collection assembly 7 is provided at the upper end of the transmission module 3, and the collection assembly 7 uniformly collects the diodes 1 that fail the detection.

[0024] The working principle of this embodiment is that the diodes 1 are conveyed one by one from the discharging assembly to the lower end of the conveying module 3, and then the conveying module 3 conveys the diodes 1 upwards. When the diodes 1 are conveyed to the second section conveying module 3, the upper end of the diodes 1 is subjected to a conductivity detection by the conductive detection module 5. If the conductive detection module 5 detects that the diodes 1 are energized, the corresponding conveying pickup module 4 picks up the diodes 1 and conveys them to the next process. If not energized, the corresponding telescopic traction assembly of the second section conveying module 3 drives it to move in the front-to-back direction. At this time, the diodes 1 are above the conveying module 3, and then the diodes 1 and the conveying module 3 move. The diode 1 is contacted with the baffle 6 on the side, so that the diode 1 rotates, thereby exchanging the position of the pin of the diode 1; the conductive detection module 5 performs another detection, and if it is energized, the transmission pickup module 4 picks it up and transmits it to the next transmission component. If it is not conductive, it continues to be transmitted upward to the next transmission module 3, and in the process of upward transmission, the upper end of the diode 1 is turned downward by the conductive detection module 5, and the positions of the upper and lower ends are exchanged, and then the above detection is performed at the next conductive detection module 5. If it is still detected that the diode 1 is not energized, it continues to be transmitted to the upper end of the transmission module 3, and the diode 1 is collected in the collection component 7. This design can perform multi-level detection on the diode 1, and perform refined detection on the diode 1 during the detection process. At the same time, this set of devices can also perform a variety of different detections on the diode according to actual conditions, that is, each group of detection modules 2 can be adaptively adjusted according to actual detection needs, such as different voltage detection of the diode 1.

[0025] In this embodiment, an implementation of the transmission and picking module 4 is that the transmission and picking module 4 includes a mobile transmission module and a picking module, wherein an implementation of the mobile transmission module is that a group of horizontally distributed chain rollers 8 are provided above the transmission module 3, and the outer sides of each group of chain rollers 8 are linked by chain belts 9, and a plurality of placement seats 10 are installed on the outer sides of the chain belts 9 along their length direction, and the placement seats 10 are made of foam or foam cotton and other materials to facilitate the insertion of the pins of the diode 1; at the same time, the picking module 4 is installed on the side of the chain roller 8 close to the transmission module 3, and an implementation of the picking module is that a mechanical arm 11 is installed on the front side of the chain roller 8 close to the transmission module 3, and a clamping claw 12 is installed at the free end of the mechanical arm 11, under the action of the mechanical arm 11, the clamping claw 12 extends into between the two baffles 6 to clamp the tube head of the diode 1, and when the conductive detection module 5 detects that the diode 1 corresponding to the transmission module 3 is energized at this time, the clamping claw 12 of the mechanical arm 11 clamps the diode 1, and inserts the pins of the diode 1 into the placement seat 10 above the chain roller 8 through the mechanical arm 11.

[0026] One implementation of the conductive detection module 5 includes an electric telescopic rod 13, which is located on the side of the transmission pickup component 4 close to the transmission module 3. The fixed part of the electric telescopic rod 13 is provided with a power component for driving rotation. The power component can be a servo or other implementations with the same function. The free end of the electric telescopic rod 13 is installed with an arc block 14 through a connecting rod. The concave surface of the arc block 14 faces the lower end of the transmission module 3. Two electrodes 15 are installed on the concave side of the arc block 14. The electrodes 15 are respectively connected to the two poles of the power supply, and there is a detection sensor in the circuit corresponding to the electrode 15. When the two pins of the diode 1 are respectively in contact with the two motors 15, the detection sensor detects whether the corresponding circuit is energized, thereby feeding back the information to the controller (not shown in the figure) through the detection sensor. The controller enables the corresponding transmission and picking module 4 to pick up the diode 1 and transmit it to the next process. At the same time, if the diode 1 is not energized, and the diode 1 is rotated by the telescopic moving component, and the two pins are changed, but it is still not energized, then the diode 1 may be in a state where the tube head is facing up and the tube pins are facing down. Therefore, the transmission module 3 continues to transmit the diode 1 upward, and the electric telescopic rod 13 rotates the angle and adjusts the length at the same time under the action of the power component, and the upper end of the diode 1 is pushed upward by the arc block 14, so that the upper and lower sides of the diode 1 are flipped, so that the position of the tube pins and the tube head of the diode 1 changes, and the electric telescopic rod 13 continues to rotate, so that the diode 1 continues to move to the upper section of the transmission module 3 under the action of the transmission module 3, and the above-mentioned detection can be repeated.

[0027] In an optional embodiment, each section of the conveying module 3 includes a group of belt rollers 16, each group of belt rollers 16 includes four belt rollers 16 distributed at the four corners of a rectangle, and the outer sides of each group of belt rollers 16 are connected by a conveyor belt 17, and each group of belt rollers 16 is provided with a first driving component for driving it to rotate. The first driving component belongs to a mature existing technology and will not be described in detail here, and the diode 1 is transported by several sections of conveyor belts 17.

[0028] In an optional embodiment, the movable telescopic component includes a mounting bracket 18, each group of belt rollers 16 includes a mounting bracket 18 for installation, and the mounting bracket 18 is provided with a second driving component for driving the corresponding group of belt rollers 16 to rotate. At the same time, an electric push rod 19 is provided on the rear side of each mounting bracket 18, and the entire group of belt rollers 16 and the conveyor belt 17 are driven to move by the extension and retraction of the electric push rod 19.
