Description

Technical Field

[0001] This utility model relates to the field of integrated circuit testing technology, specifically to a testing station for integrated circuit testing. Background Technology

[0002] Before being packaged, integrated circuit components are tested on a wafer to determine their electrical characteristics. Good integrated circuits are selected for subsequent packaging, while defective ones are discarded. This requires the use of testing stations and testing equipment.

[0003] Utility model patent CN215812937U discloses a multifunctional testing platform for integrated circuit testing. It solves the problems of existing testing platforms being simple in structure, difficult to adjust, and lacking functionality, thus failing to protect the testing equipment and leading to a short lifespan. The platform incorporates a testing storage box, allowing for the storage of both the main and auxiliary testing equipment when not in use, improving protection. By including a first lead screw, transmission belt, drive nut block, L-shaped top rod, second lead screw, testing platform, and drive motor, the platform facilitates automatic height adjustment of the main testing equipment and enables its storage. An auxiliary testing mechanism is also included to improve testing efficiency and avoid additional packaging costs. While the structure is simple, in practice, although the height of the main testing equipment can be adjusted, the height of the auxiliary testing equipment cannot. Furthermore, the operator needs to manually rotate the auxiliary testing equipment, which is prone to slippage and significant shaking, potentially damaging the auxiliary equipment and rendering it inconvenient to use.

[0021] refer to Figure 1 The storage box 2 has sliding grooves on the front and rear sides of the top, and movable plates 11 are slidably connected to both sides inside the sliding grooves. The top of the movable plates 11 has an opening 12. Support blocks 13 are fixedly connected to the front and rear sides of the top of the movable plates 11. Movable frames 14 are rotatably connected inside the support blocks 13. Auxiliary detection equipment 15 is fixedly connected to the bottom of the movable frames 14. A first motor 16 is fixedly connected to the front of the front support block 13. The output end of the first motor 16 is fixedly connected to the movable frames 14.

[0022] As a technical optimization of this utility model, by setting up a sliding groove, a movable plate 11, a through-hole 12, a support block 13, a movable frame 14 and a first motor 16, the operator pulls the movable plate 11 to both sides, and then the operator starts the first motor 16 to drive the movable frame 14 to rotate 180 degrees, thereby rotating the auxiliary detection device 15 above the movable plate 11. The first motor 16 is a servo motor.

[0023] refer to Figure 3The drive assembly 7 includes a drive box 17 fixedly connected to the top of the base plate 1. A threaded rod 18 with positive and negative threads is rotatably connected inside the drive box 17. Drive columns 19 are slidably connected to both sides inside the drive box 17. The drive columns 19 are fixedly connected to the movable block 5. The drive columns 19 are threadedly connected to the threaded rod 18 with positive and negative threads. A second motor 20 is fixedly connected to the right side of the drive box 17. The output end of the second motor 20 is fixedly connected to the threaded rod 18 with positive and negative threads.

[0024] As a technical optimization of this utility model, by setting the drive component 7, for example, the operator can start the second motor 20 to rotate and drive the positive and negative thread rod 18 to rotate, thereby driving the drive columns 19 on both sides to move closer to each other, thereby driving the movable blocks 5 on both sides to move closer to each other, thereby driving the connecting plate 6 to move, thereby driving the storage box 2 to move upward, thereby driving the main detection device 10 and the auxiliary detection device 15 to move upward, thereby adjusting the height of the main detection device 10 and the auxiliary detection device 15.

[0025] refer to Figure 2 T-shaped grooves are provided on both sides of the bottom of the inner wall of the storage box 2. T-shaped strips 27 are slidably connected inside the T-shaped grooves, and storage boxes 28 are fixedly connected to the top of the T-shaped strips 27.

[0026] As a technical optimization of this utility model, by setting up the T-shaped groove, the T-shaped strip 27 and the storage box 28, the storage box 28 can hold items, and the operator can slide the T-shaped strip 27 out of the T-shaped groove and then remove the storage box 28.

[0027] refer to Figure 1 The bottom of the base plate 1 is fixedly connected to the four sides with casters 22, and the top of the right movable plate 11 is fixedly connected to the handrail 23.

[0028] As a technical optimization of this utility model, the universal wheels 22 and the handrail 23 make it easier for the operator to move the device. The universal wheels 22 have a self-locking structure. The universal wheels 22 are common existing technology and will not be described in detail in this application.

[0029] refer to Figure 1 The storage box 2 has sealed doors 21 on both sides of the front. The surface of the sealed doors 21 has an observation window. The storage box 2 has support rods 24 hinged on both sides of the front and back. The movable plate 11 has slots on both the front and back. The support rods 24 have a first threaded rod 25 inside. The first threaded rod 25 is threaded to the slot. The first threaded rod 25 is fixedly connected to a handle 26 on the side of the first threaded rod 25 away from the movable plate 11.

[0030] As a technical optimization of this utility model, the storage box 2 can be sealed and protected by the sealing door 21 and the observation window. With the support rod 24, the slot, the first threaded rod 25 and the handle 26, when the operator pulls the movable plate 11 to both sides, the operator can rotate the support rod 24 so that the opening on the surface of the support rod 24 is aligned with the slot. The operator then inserts the first threaded rod 25 through the opening and threadedly connects it with the slot, so that the support rod 24 provides auxiliary support for the movable plate 11, thereby improving the stability of the movable plate 11.

[0031] The working principle and usage process of this utility model are as follows: During use, the operator can adjust the movable blocks 5 on both sides to move closer or further apart, thereby moving the connecting plate 6. For example, when the movable blocks 5 on both sides move closer together, the connecting plate 6 moves the storage box 2 upwards, which in turn moves the electric cylinder 8, support plate 9, main detection device 10, movable plate 11, and auxiliary detection device 15 upwards, thus adjusting the height of the main detection device 10 and auxiliary detection device 15. The operator can activate the electric cylinder 8 to extend, thereby moving the support plate 9 and main detection device 10 upwards, making it easier for the operator to use the main detection device 10. During testing, the operator starts the first motor 16 to rotate the movable frame 14 180 degrees, thereby rotating the auxiliary testing equipment 15 above the movable plate 11. The main testing equipment 10 and the auxiliary testing equipment 15 mentioned above are similar in principle to those mentioned in the utility model patent disclosed in CN215812937U, which discloses a multifunctional testing platform for integrated circuit testing, and achieve the same effect. This application will not elaborate further. The movable column 4 slides up and down inside the cylinder 3, thereby ensuring that the base plate 1 can move up and down stably.
