[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A chip testing and positioning device includes a chip body 1 and a vertical base 2. A mounting plate 14 is fixedly mounted on the lower side of the vertical base 2. The upper side of the mounting plate 14 has several mounting holes 15. Several reinforcing ribs are fixed between the upper side of the mounting plate 14 and one side of the vertical base 2. Before use, the mounting plate 14 can be installed and fixed by bolts passing through the mounting holes 15. A stabilizing frame 22 is fixedly mounted on one side of a rotating plate 4. A rotating plate 4 is located on one side of the vertical base 2, and a plurality of clamping assemblies are located on one side of the rotating plate 4. The clamping assemblies are arranged circumferentially. The component is used to position the chip. The clamping assembly includes a fixing frame 6, which is fixed to the stabilizing frame 22 and to one side of the rotating plate 4. The fixing frame 6 has a U-shaped structure. A support plate 7 is fixedly installed on the inner side of the fixing frame 6. A protective pad 8 and a protective frame 9 are sequentially fixed on one side of the support plate 7. The protective frame 9 has a U-shaped structure. The chip body 1 is detachable inside the protective frame 9. The protective frame 9 is fixed to the inner side of the fixing frame 6. A movable seat 10 is slidably installed on the inner side of the fixing frame 6. A protective strip 11 is fixedly installed on one side of the movable seat 10. The protective pad 8, Both the protective frame 9 and the protective strip 11 are flexible structures. The chip body 1 is detachable between the protective frame 9 and the protective strip 11. Guide holes are provided on both sides of the fixing bracket 6 that are far apart. The movable seat 10 slides inside the guide holes. A threaded hole is provided on one side of the movable seat 10. A threaded rod 12 is connected to the inside of the threaded hole through a threaded drive. A through hole is provided on one side of the rotating plate 4. The threaded rod 12 rotates inside the through hole. A hexagonal head 13 is fixed at one end of the threaded rod 12. When this positioning device is in use, if it is necessary to position the chip, the chip must first be placed in the protective frame 9. Inside the protective frame 9, rotate the hexagonal head 13 and the threaded rod 12. When the threaded rod 12 rotates, it causes the movable seat 10 to move within the guide hole. By rotating the threaded rod 12, the movable seat 10 and the protective strip 11 can automatically approach the protective frame 9 and the chip. When the movable seat 10 contacts the support plate 7, the chip can be clamped between the protective frame 9 and the protective strip 11. At this point, the chip can be clamped and positioned. Moreover, the protective pad 8, the protective frame 9, and the protective strip 11 are all made of flexible material, so they can protect the chip and prevent it from being damaged by clamping.

[0023] A switching assembly is provided between the vertical base 2 and the rotating plate 4. The switching assembly includes a switching shaft 3. A through hole is provided on one side of the vertical base 2. The switching shaft 3 rotates inside the through hole. One end of the switching shaft 3 is fixed to one side of the rotating plate 4. A stepper motor 5 is fixed on one side of the vertical base 2. The stepper motor 5 is externally connected to a stepper motor driver through wires. The shaft end of the stepper motor 5 is connected to the outer periphery of the switching shaft 3 through bevel gear transmission. During chip testing, when a chip is tested and the next chip needs to be replaced, the stepper motor 5 can be controlled to rotate a certain number of revolutions. When the stepper motor 5 rotates, it will drive the switching shaft 3, the rotating plate 4, several clamping components and the chip to make circular motion together through the bevel gear. By controlling the number of revolutions of the stepper motor 5, the rotating plate 4 can be controlled to rotate a certain angle, so as to accurately control the next chip to rotate to the test position, thereby realizing automatic switching without waiting for a long replacement time and improving testing efficiency.

[0024] Two clamping and releasing assemblies are provided on the other side of the rotating plate 4. These assemblies are used to drive the clamping assembly to automatically clamp and release. Each clamping and releasing assembly includes a guide rod 16, one end of which is fixed to one side of the vertical seat 2. A reciprocating seat 17 slides on the outer periphery of the guide rod 16. One side of the reciprocating seat 17 has a connecting hole and a round hole. A cylinder 18 is fixed inside the connecting hole, and the shaft end of the cylinder 18 is fixed to one side of the vertical seat 2. The cylinder 18 is connected to a solenoid valve via an air pipe. A connecting ring 19 is rotatably mounted inside the round hole. An electric motor 20 is fixed to one side of the reciprocating seat 17. The electric motor 20 is connected to a power source and switch via wires. The shaft end of the electric motor 20 is connected to the outer periphery of the connecting ring 19 via a bevel gear transmission. A hexagonal sleeve 21 is fixed inside the connecting ring 19. The hexagonal sleeve 21 matches a hexagonal head 13, which is detachably fitted inside the hexagonal sleeve 21. Both the corner sleeve 21 and the hexagonal head 13 have several rounded corners. During chip testing, when it is necessary to remove the chip from the clamping assembly or install the chip onto the clamping assembly, the cylinder 18 can be extended or retracted to move the hexagonal sleeve 21 away from or closer to the hexagonal head 13. When the cylinder 18 retracts, the hexagonal sleeve 21 will approach and fit onto the hexagonal head 13. Then, the electric motor 20 is controlled to rotate in a certain direction. When the electric motor 20 rotates, it will drive the connecting ring 19 and the hexagonal sleeve 21 to rotate together through the bevel gear. The hexagonal sleeve 21 can drive the hexagonal head 13 to rotate. When the hexagonal head 13 rotates, the moving seat 10 can be moved horizontally, thereby driving the clamping assembly to automatically clamp and release. This allows the chips on both sides to be installed or removed while testing the top chip, enabling chip testing and chip replacement to be performed simultaneously, thereby further improving testing efficiency.

[0025] It should be noted that the stepper motor 5 and electric motor 20 mentioned in this application are existing technologies, and their specific usage methods and functions will not be described in detail here.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
