[0026] Please refer to Figure 1-7 , the present utility model provides a technical solution: a detection device for GaO diode production, including a bottom plate 1 and a detection plate 3. Four support legs 2 are provided at the bottom of the bottom plate 1. Four first guide posts 4 are provided at the upper end of the bottom plate 1 near the four corners. The first guide posts 4 penetrate through the detection plate 3, and the detection plate 3 is slidably connected to the first guide posts 4;

[0027] A limit block 5 is provided on the first guide post 4, and the detection plate 3 is located above the limit block 5;

[0028] A plurality of detection ports 6 are provided at the upper end of the detection plate 3. A detection groove 7 is provided at the lower end of the detection port 6, and the detection groove 7 penetrates through the bottom of the detection plate 3;

[0029] Among them, the detection plate 3 is used to install the GaO diode for subsequent detection. During detection, the GaO diode is placed into the detection port 6, and the contact pins of the GaO diode are inserted into the detection groove 7, waiting for subsequent clamping and energized detection.

[0030] A clamping device is provided at the lower end of the detection plate 3. The clamping device includes a fixed plate 8 and a clamping plate 9. The fixed plate 8 and the clamping plate 9 are respectively located on both sides of the detection groove 7. The fixed plate 8 is fixedly installed at the bottom of the detection plate 3. The clamping plate 9 is movably arranged, and the clamping plate 9 is controlled to move by a cylinder 10;

[0031] A plurality of groups of L-shaped blocks 11 are provided inside the fixed plate 8. The L-shaped blocks 11 and the detection ports 6 are in a vertically corresponding position. Clamping blocks 12 matching the L-shaped blocks 11 are provided inside the clamping plate 9. The clamping blocks 12 are controlled by the cylinder 10 to contact or separate from the L-shaped blocks 11;

[0032] The L-shaped blocks 11 and the clamping blocks 12 are made of metal;

[0033] The fixing plate 8 is provided with second guide posts 13 near both sides. The second guide posts 13 penetrate through the clamping plate 9, and the clamping plate 9 is slidably connected to the guide posts.

[0034] Among them, the clamping device is used to clamp the pins of the GaO diode, facilitating subsequent power supply to the GaO diode. The air cylinder 10 drives the clamping plate 9 to approach the fixing plate 8, so that the clamping blocks 12 inside the clamping plate 9 approach the L-shaped blocks 11 inside the fixing plate 8 and clamp the pins of the GaO diode.

[0035] A plurality of gears 14 are rotatably installed at the upper end of the bottom plate 1. The gears 14 are arranged in a row, and adjacent gears 14 are meshed. The upper end of the gear 14 is provided with a power-on contact pin 15, and the upper end of the power-on contact pin 15 abuts against the lower end of the L-shaped block 11.

[0036] The gear 14 is driven by a motor 16, and the motor 16 is fixedly installed at the lower end of the bottom plate 1.

[0037] Among them, the power-on contact pin 15 can be powered on or off according to the detection process. After the clamping device clamps the pins of the GaO diode, the upper end of the power-on contact pin 15 abuts against the lower end of the L-shaped block 11. At this time, the power-on contact pin 15 is powered on to detect the forward voltage of the GaO diode.

[0038] After the forward voltage detection is completed, the motor 16 drives the gear 14 to rotate 180 degrees, so that the power-on contact pin 15 also rotates 180 degrees, causing the two contact pins on the power-on contact pin 15 to exchange positions, and then the reverse voltage of the GaO diode is detected.

[0039] A jacking device is provided between the bottom plate 1 and the detection plate 3, and there are two groups of jacking devices. The jacking device includes a circular block 17, the circular block 17 is fixedly installed at the lower end of the detection plate 3, and an arc-shaped track 18 is provided at the lower end of the circular block 17.

[0040] The upper end of the gear 14 is provided with a column 19, the upper end of the column 19 is provided with a roller frame 20, and a roller 21 is rotatably installed inside the roller frame 20. The roller 21 is tangent to the arc-shaped track 18.

[0041] When the power-on contact pin 15 rotates, the detection plate 3 can be lifted by the jacking device, so that the power-on contact pin 15 is separated from the L-shaped block 11, preventing the power-on contact pin 15 from rubbing against the L-shaped block 11. The rotation of the gear 14 drives the rotation of the column 19, and the column 19 drives the roller 21 to rotate along the arc-shaped track 18 through the roller frame 20. During the rotation of the roller 21, the power-on contact pin 15 is always separated from the L-shaped block 11. After rotating 180 degrees, the power-on contact pin 15 contacts the L-shaped block 11.

[0042] The working principle and usage process of the present utility model:

[0043] When detecting, place the GaO diode into the detection port 6, and insert the pins of the GaO diode into the detection slot 7. Clamp the pins of the GaO diode through the clamping device. The cylinder 10 drives the clamping plate 9 to approach the fixed plate 8, so that the clamping block 12 inside the clamping plate 9 approaches the L-shaped block 11 inside the fixed plate 8 and clamps the pins of the GaO diode. The energized pin 15 can be energized or de-energized according to the detection process. After the clamping device clamps the pins of the GaO diode, the upper end of the energized pin 15 abuts against the lower end of the L-shaped block 11. At this time, the energized pin 15 is energized to detect the forward voltage of the GaO diode; after the forward voltage detection is completed, the motor 16 drives the gear 14 to rotate 180 degrees, so that the energized pin 15 also rotates 180 degrees, making the two pins on the energized pin 15 exchange positions, and then detect the reverse voltage of the GaO diode; when the energized pin 15 rotates, the lifting device can lift the detection plate 3, so that the energized pin 15 is separated from the L-shaped block 11 to prevent the energized pin 15 from rubbing against the L-shaped block 11. The rotation of the gear 14 drives the rotation of the column 19, and the column 19 drives the roller 21 to rotate along the arc track 18 through the roller frame 20. During the rotation of the roller 21, the energized pin 15 is always separated from the L-shaped block 11. After rotating 180 degrees, the energized pin 15 contacts the L-shaped block 11.
