[0002] A photodiode array detector chip is a photoelectric conversion device based on semiconductor technology. By integrating multiple photodiode units on a single substrate to form an array structure, it can realize multi-point parallel acquisition and processing of optical signals. Its core principle is to convert incident photons into electrical signals through the photoelectric effect. During the production and transportation of the chip, a moving device is often required to move the chip, thereby facilitating chip production.

[0003] Regarding the prior art patent CN221466547U, a transfer device for chip sorting equipment is disclosed, including a base, a first motor is provided on the top of the base, and a vertical rod is provided on one side of the first motor. The other end of the vertical rod is fixedly connected to a horizontal rod. A weight-adding box is provided at one end of the horizontal rod, and a second motor is provided at the other end of the horizontal rod. An arm is fixedly connected to the output end of the second motor, and a gripping component is provided at the other end of the arm. By setting the first motor and the second motor, the position of the gripping component is adjusted. When the chip is at the bottom of the gripping component, a vacuum pump is started to fix the chip with a silicone suction nozzle. Then, an electric push rod is started to move the sleeve upward, thereby achieving the effect of fixing the chip with a rubber pad. This transfer device for chip sorting equipment greatly improves the stability during chip transfer.

[0004] However, existing photodiode array detector chip sorting and transfer devices are inconvenient to move due to their large size. They require manual handling or external tools, which consumes a lot of time and manpower. In addition, the device generates huge vibrations during movement, which can easily cause the chips to fall off, affecting subsequent work efficiency. Utility Model Content

[0005] In order to overcome the problems of existing chip sorting and transfer devices being too large, inconvenient to move, time-consuming and labor-intensive, and prone to chip falling due to vibration during movement, thus affecting subsequent work efficiency.

[0023] Please see Figures 1-5This utility model provides an embodiment of a sorting and transferring device for photodiode array detection chips, including a base 2, a sorting and transferring module disposed above the base 2, and a lifting module disposed below the base 2. The lifting module includes a housing 1, with through holes 5 at each of the four ends inside the housing 1. A driving component is disposed at one end of the housing 1, and a worm gear 7 is connected to the output end of the driving component. A worm wheel 9 is disposed on one side of the worm gear 7, and a rotating shaft 8 is connected through the inside of the worm wheel 9. A lead screw 10 is fixedly connected to one end of the rotating shaft 8, and a threaded block 11 is sleeved on the outside of the lead screw 10. Connecting blocks 12 are fixedly connected to the front and rear ends of the left and right sides of the threaded block 11. The lower part of the four connecting blocks 12... The support block 13 is provided, and a buffer assembly is provided inside the support block 13. A universal wheel 4 is provided at one end of the buffer assembly. The buffer assembly includes a damper 15. Movable grooves 18 are provided on both the left and right sides inside the support block 13. Guide components are provided inside the two movable grooves 18. An elastic element is sleeved on the outside of the damper 15. An upper fixed plate 14 is provided above the damper 15, and a lower fixed plate 17 is provided below the upper fixed plate 14. The structure of the worm 7, worm wheel 9, lead screw 10 and motor 3 is the existing technical solution. Here, the applicant will not provide a detailed description of the internal structure and components of the worm 7, worm wheel 9, lead screw 10 and motor 3 or their connection relationship.

[0024] The driving component includes a motor 3, the output end of which is connected to a worm gear 7. A worm wheel 9 is meshed with one side of the worm gear 7. The motor 3 drives the worm gear 7 to rotate, which in turn drives the worm wheel 9 to rotate. The rotation of the worm wheel 9 drives the internally connected rotating shaft 8 to rotate. A lead screw 10 fixedly connected to one end of the rotating shaft 8 also rotates. The rotation of the lead screw 10 drives the externally meshed threaded block 11 to move up and down, which in turn drives the universal wheels 4 to move up and down. Four support blocks 13 are connected to the outer shell 1 through four through holes 5. The motor 3 drives the worm gear 7 to rotate. When the worm gear 7 rotates, it drives the worm wheel 9 meshed with it to rotate. When the worm wheel 9 rotates, it drives the internally connected rotating shaft 8 and lead screw 10 to rotate. At the same time, the threaded block 11 meshed with the lead screw 10 moves up and down, and drives the four universal wheels 4 to move up and down. The support blocks 13 and the through holes 5 drive the universal wheels 4 to rise and fall, making contact with the ground for easy movement, and then moving upwards to be stored inside the outer shell 1.

[0025] The elastic element includes a first buffer spring 16, which is sleeved on the outside of the damper 15. An upper fixed plate 14 is fixedly connected to one end of the damper 15, and a lower fixed plate 17 is fixedly connected to the other end of the damper 15 for buffering the caster wheel 4. Connecting plates 6 are fixedly connected to the lower end face of the lower fixed plate 17 on both sides of the caster wheel 4. A drive shaft is connected through the caster wheel 4 to the two connecting plates 6 for rotation of the caster wheel 4. The guide assembly includes guide rods 20, which are located within the movable groove 18 and fixedly connected to the inner wall of the support block 13. Guide blocks that are slidably sleeved on the outside of the two guide rods 20 are fixedly connected to both sides of the lower fixed plate 17. One end of the block is fixedly connected to a second buffer spring 19 sleeved on the outside of the guide rod 20 for guiding and buffering the universal wheel 4. During the movement, the damper 15 and the first buffer spring 16 work together to reduce vibration. The upper fixed plate 14 and the lower fixed plate 17 are both fixedly connected to the damper 15. The universal wheel 4 is provided with connecting plates 6 fixedly connected to the lower end face of the lower fixed plate 17 on both sides. At the same time, the guide blocks sleeved on the two guide rods 20 on the left and right sides of the lower fixed plate 17 slide, and the second buffer spring 19 is compressed to buffer and improve the stability of the universal wheel 4, prevent the chip from falling off during the movement, and improve the overall work efficiency.

[0026] During operation, the worm gear 7 is driven to rotate by the motor 3. The worm gear 7 drives the worm wheel 9, which is meshed with it on one side, to rotate. This, in turn, drives the internally penetrating shaft 8 and lead screw 10 to rotate. At the same time, the threaded block 11 sleeved on the lead screw 10 moves up and down, and drives the four universal wheels 4 to move and contact the ground for easy movement. During the movement, the damper 15 and the first buffer spring 16 work together to reduce vibration. At the same time, the guide rods 20 on the left and right sides guide the universal wheels 4 to improve stability and prevent the chip from falling off during movement, thereby improving overall work efficiency.

[0027] Through the above steps, the lifting mechanism adjusts the vertical displacement of the casters 4. During the movement of the equipment, the casters 4 move downwards to contact the ground for easy movement. When the equipment is in use, the casters 4 move upwards for storage. The flexible lifting mechanism facilitates the movement of the equipment, saves time and effort, and improves work efficiency. This solves the problem that existing chip sorting and transfer devices are too large, making subsequent movement inconvenient, time-consuming, and labor-intensive. Furthermore, they generate vibrations during operation, which can easily cause chips to fall and affect subsequent work efficiency.
