In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0023] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0024] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use.

Therefore, they cannot be understood as a limitation on the present invention.

[0025] like Figures 1 to 4As shown, a multi-purpose semiconductor chip test fixture includes a frame 1, a support table 3 is provided on the inner side of the frame 1, a movable adjustment assembly 2 is provided on the surface of the frame 1 for controlling the movement of the support table 3, and a plurality of test sockets 4 of different specifications for testing chips are placed on the top surface of the movable adjustment assembly 2. The test sockets 4 are electrically connected to the test equipment. A chip positioning assembly 6 is provided above the support table 3 for limiting the position of the chip. The surface of the frame 1 is also provided with a lifting assembly 5 for controlling the docking of the test sockets 4 with the chip positioning assembly 6. More specifically, the movable adjustment assembly 2 is operated to drive the support table 3 to move horizontally, so that different test sockets 4 are aligned with the chip positioning assembly 6. The test socket 4 required for the test is selected so that the test socket 4 is directly below the chip positioning assembly 6. The lifting assembly 5 is operated to push the test socket 4 up, so that the test socket 4 is locked into the chip positioning assembly 6. The chip to be tested is placed in the chip positioning assembly 6, and the chip positioning assembly 6 is used to press and limit the chip, so that the chip and the test socket 4 are tightly connected, and the chip can now be tested.

[0026] The movement and adjustment assembly 2 includes a motor 201, which is fixedly mounted on the inner wall of the frame 1. The output end of the motor 201 is fixedly connected to a threaded column 202, which is threadedly connected to the support platform 3. The inner wall of the frame 1 is fixedly connected to a slide column 203, which is slidably connected to the support platform 3. It should be noted that when the threaded column 202 is driven to rotate by the motor 201, the threaded column will push the support platform 3 to slide along the surface of the slide column 203 under the action of the thread, so that different test sockets 4 are aligned with the chip positioning assembly 6.

[0027] The chip positioning assembly 6 includes a mounting frame 601, which is fixedly connected to the frame 1. The front end of the mounting frame 601 is fixedly connected to the test bench 602. The top surface of the mounting frame 601 is rotatably connected to an adjusting screw 603. The surface of the adjusting screw 603 is threadedly connected to a connecting column 604. The end of the connecting column 604 is fixedly connected to a clamping plate 606. The top surface of the mounting frame 601 is fixedly connected to a limiting rod 605, and the limiting rod 605 is slidably connected to the connecting column 604. More specifically, after the test socket 4 is inserted into the test bench 602, the chip to be tested is placed into the test bench 602. By rotating the adjusting screw 603, the connecting column 604 is driven to slide along the surface of the limiting rod 605 under the action of the thread, thereby pushing the clamping plate 606 down, so that the clamping plate 606 contacts the top surface of the chip, clamping and positioning the chip.

[0028] The lifting assembly 5 includes an electric push rod 501, which is fixedly mounted on the surface of the frame 1. The telescopic end of the electric push rod 501 is fixedly connected to the lifting frame 502. A positioning hole 504 is formed through the surface of the support table 3. A slot 505 is formed on the bottom surface of the test socket 4. The inner wall of the positioning hole 504 and the inner wall of the slot 505 are both movably connected to the end of the lifting frame 502. It should be noted that the operation of the electric push rod 501 drives its telescopic end to shorten, thereby pulling the lifting frame 502 up. The end of the lifting frame 502 will pass through the inner wall of the positioning hole 504 and insert into the slot 505, lifting the test socket 4 so that the test socket 4 can be inserted into the interior of the chip positioning assembly 6, thereby facilitating testing.

[0029] A spring 503 is fixedly connected to the bottom of the inner wall of the support platform 3, and the free end of the spring 503 is fixedly connected to the bottom surface of the test socket 4. More specifically, the provision of the spring 503 can limit the position of the test socket 4, so that the test socket 4 is stably maintained on the top surface of the support platform 3, and when the test socket 4 is reset from the chip positioning assembly 6, it can be ensured to return smoothly.

[0030] Support blocks are fixedly connected to the left and right sides of the bottom surface of the frame 1, and rubber pads are fixedly connected to the bottom surface of the pressure plate 606. It should be noted that the support blocks create a gap between the bottom of the frame 1 and the placement surface, thereby accommodating the installation of the lifting assembly 5. The rubber pads on the bottom surface of the pressure plate 606 make the contact surface with the chip softer, avoiding pressure damage to the chip surface.

[0031] In summary: by moving the adjustment component 2, the support platform 3 is driven to move horizontally, so that different test sockets 4 are aligned with the chip positioning component 6, and the test socket 4 required for this test is selected so that the test socket 4 is located directly below the chip positioning component 6. By operating the lifting component 5, the test socket 4 is pushed up, so that the test socket 4 is stuck in the chip positioning component 6, and the chip to be tested is placed in the chip positioning component 6. It is pressed and limited by the chip positioning component 6, so that the chip and the test socket 4 are tightly connected. At this time, the chip can be tested, and the effect of facilitating rapid testing of the chip is achieved during use. The corresponding test socket 4 can be selected for testing according to different chips, thereby expanding its scope of application and making it more convenient and flexible to use.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
