[0023] like Figure 1-5 As shown, a conveying device for chip testing includes a support 1, a conveyor belt 2 installed inside the support 1 for conveying chips, and a square box 3 on the support 1. The square box 3 is added to the front and rear sides of the support 1, and its left and right sides are through-connected. Chips can enter from one side of the square box 3, be processed, and then be sent out from the other side.

[0024] The correction components are symmetrically distributed on both sides of the square box 3, including a horizontal bar 4 that runs horizontally through the side wall of the square box 3 and is slidably connected thereto. A correction plate 5 is fixedly connected to the end of the horizontal bar 4. The correction plate 5 is located inside the square box 3 and is used to contact and correct the position of the chip. A guide plate 6 is fixedly connected to the outer wall of the square box 3. A sliding plate 7 is slidably connected to the guide plate 6. The horizontal bar 4 runs horizontally through the sliding plate 7 and is slidably connected thereto. A spring 8 is sleeved on the horizontal bar 4. The two ends of the spring 8 are fixedly connected to the sliding plate 7 and the horizontal bar 4, respectively. The elasticity of the spring 8 can make the correction plate 5 form a flexible clamping force on the chip.

[0025] A stepper motor 9 is fixedly installed on the bottom wall of the square box 3. A threaded rod 10 is fixedly connected to the output end of the stepper motor 9. An adjusting plate 11 is threadedly connected to the threaded rod 10. A bottom rod 12 is fixedly connected to the bottom wall of the square box 3 in a symmetrical arrangement with respect to the stepper motor 9. The adjusting plate 11 is slidably connected to the bottom rod 12 to ensure the stability of the adjusting plate 11 when it moves. A connecting rod 13 is hinged between the adjusting plate 11 and the sliding plate 7. When the stepper motor 9 is working, it can drive the adjusting plate 11 to move through the threaded rod 10, and then drive the sliding plate 7 to slide on the guide plate 6 through the connecting rod 13.

[0026] The drying assembly is mounted on the square box 3, including an air pump 14 fixedly installed on the top of the square box 3. A heating box 15 is fixedly connected to the top of the square box 3. The heating box 15 has evenly distributed electric heating wires inside. The output end of the air pump 14 is located inside the heating box 15, which can send outside air into the heating box 15. A diversion pipe 16 is fixedly connected to the inner top of the square box 3. Evenly distributed nozzles 17 are fixedly connected to the bottom of the diversion pipe 16. The diversion pipe 16 communicates with the inside of the heating box 15. The air heated by the heating box 15 can be sprayed out from the nozzles 17 through the diversion pipe 16.

[0027] An arc-shaped heat insulation plate 18 is fixedly connected to the inner top wall of the square box 3. The heat insulation plate 18 is located directly below the nozzle 17. A temperature sensor 19 is provided on the bottom wall of the heat insulation plate 18 to monitor the temperature inside the square box 3.

[0028] A servo motor 20 is fixedly installed on the bracket 1. The output end of the servo motor 20 is fixedly connected to the feeding plate 21. The top wall of the feeding plate 21 is provided with evenly distributed grooves 22. A limiting plate 23 is inserted inside the grooves 22. The limiting plate 23 is made of metal and is attracted to the grooves 22. The position of the limiting plate 23 can be adjusted according to the chip size.

[0029] The working principle of this utility model is as follows: The chip is placed on the conveyor belt 2, and the conveyor belt 2 drives the chip to move. According to the size of the chip, the stepper motor 9 is started. The stepper motor 9 drives the threaded rod 10 to rotate, so that the adjusting plate 11 moves along the bottom rod 12. The adjusting plate 11 drives the sliding plate 7 to slide on the guide plate 6 through the connecting rod 13. The sliding plate 7 drives the crossbar 4 to move, thereby adjusting the distance between the two correction plates 5. The spring 8 on the crossbar 4 is in an appropriate compressed state, so that the correction plate 5 can form a flexible clamp on the chip.

[0030] After the chip enters the square box 3, it can avoid shifting or tipping under the action of the correction plate 5, and maintain a stable transmission state. At the same time, the air pump 14 and the electric heating wire in the heating box 15 are activated. The air pump 14 sends the outside air into the heating box 15. After being heated by the electric heating wire, the hot air is blown evenly into the inside of the square box 3 through the nozzle 17 through the diverter pipe 16 to remove moisture and small impurities from the chip surface. The heat insulation plate 18 can block some of the heat from acting directly on the chip. The temperature sensor 19 monitors the temperature inside the square box 3 in real time to prevent the chip from being damaged by excessive temperature.

[0031] During the process of conveying the chip on the conveyor belt 2, the servo motor 20 is started, and the servo motor 20 drives the unloading plate 21 to rotate. The limiting plate 23 on the unloading plate 21 plays an auxiliary guiding role for the chip, further ensuring that the chip can accurately reach the detection position. Depending on the size of the chip, the position of the metal limiting plate 23 can be adjusted through the groove 22 to adapt to different guiding requirements.
