[0028] Example 1

[0029] A chip testing device with anti-interference capabilities, such as Figures 1 to 3 As shown, the system includes a workbench 1. A first linear motion assembly 4 is mounted on the top of the workbench 1. The first linear motion assembly 4 includes a guide frame, a screw, a power motor, and a moving block. A telescopic rod 5 is fixedly connected to the moving end of the first linear motion assembly 4. The axis of the telescopic rod 5 is perpendicular to the moving direction of the moving end of the first linear motion assembly 4. A second linear motion assembly 6 is mounted on the telescopic end of the telescopic rod 5. The second linear motion assembly 6 has the same structure as the first linear motion assembly 4. A visual inspection camera 7 for visual inspection is installed on the moving end of the second linear motion assembly 6. The visual inspection camera 7 is a mature existing technology and will not be described in detail here. A supplementary light is mounted on the outside of the lens of the visual inspection camera 7. A clamping mechanism 3 located on one side of the first linear motion assembly 4 is mounted on the top outer wall of the workbench 1. A sealing cover 2 is fixedly connected to the top outer wall of the workbench 1. The sealing cover 2 covers the first linear motion assembly 4, the telescopic rod 5, the second linear motion assembly 6, the visual inspection camera 7, and part of the clamping mechanism 3.

[0030] The clamping mechanism 3 includes a rotating disk 8 and multiple clamping slots 9. The rotating disk 8 is rotatably connected to the top outer wall of the workbench 1 via a rotating rod. Half of the rotating disk 8 is located outside the closed cover 2. The side wall of the closed cover 2 is provided with a clearance groove for the rotating disk 8 to rotate. Multiple clamping slots 9 are all opened on the outer wall of the rotating disk 8 and are arranged circumferentially. One clamping slot 9 is located directly below the second linear moving component 6. A fixed rod 10 is connected to the inner wall of the clamping slot 9. Two opposing clamping plates 11 are slidably connected to the side wall of the fixed rod 10. A bidirectional lead screw 12 is rotatably connected to the inner wall of the fixed rod 10. The two clamping plates 11 are threaded to both ends of the bidirectional lead screw 12. A clamping motor 13 that drives the bidirectional lead screw 12 to rotate is installed on the outer wall of the fixed rod 10. A rotary motor that drives the rotating disk 8 to rotate is installed on the bottom outer wall of the workbench 1.

[0031] The top outer wall of the workbench 1 is provided with a touch screen 22 located on one side of the clamping mechanism 3. In this embodiment, all electrical components are electrically connected to the touch screen 22, the controller and the external mains power. The controller can be any conventional known device that can perform control, such as a computer.

[0032] During testing, the chip to be tested is placed between two clamping plates 11 in a clamping slot 9. The clamping motor 13 is started by controlling the enclosure 2, causing the two worktables 1 to move relative to each other along the fixed rod 10 and the bidirectional lead screw 12. The two clamping plates 11 clamp the chip. Then, the rotary motor drives the rotating disk 8 to rotate at a certain angle, so that the chip to be tested enters the enclosure 2 and moves to below the visual inspection camera 7. The supplementary light is lit for illumination. The first linear movement component 4, the telescopic rod 5, and the second linear movement component 6 adjust the position of the visual inspection camera 7 so that the visual inspection camera 7 can obtain better imaging effect. The enclosure 2 covers the chip, creating a stable optical inspection environment and avoiding external light interference. At the same time, it can clamp subsequent chips to be tested into other clamping slots 9. After one chip is inspected, the subsequent chips to be tested are moved to below the visual inspection camera 7 for visual inspection, realizing continuous inspection.

[0033] By incorporating a clamping mechanism 3, subsequent chips to be tested can be clamped and fixed while one chip is being tested, enabling continuous testing and improving testing efficiency.

[0034] By setting up a sealed cover 2, a stable optical detection environment is created to avoid interference from external light.

[0035] Example 2

[0036] A chip detection device with anti-interference capability is provided in this embodiment, which is based on embodiment 1 and makes the following improvements, such as... Figures 3 to 5 As shown, the rotating disk 8 is provided with a plurality of flipping components 14 for driving the fixed rod 10 to flip. The flipping component 14 includes a worm wheel 15 and a worm 16. The worm wheel 15 is connected to the rotating shaft of the fixed rod 10. The worm 16 is located on one side of the worm wheel 15 and is engaged with the worm wheel 15 in a transmission manner. The worm 16 is connected to the rotating disk 8 in a damped rotational connection. A rectangular hole 17 is provided at the bottom end of the worm 16.

[0037] The top outer wall of the workbench 1 is rotatably connected to a flower shaft 18, and the outer wall of the flower shaft 18 is slidably connected to a hollow cylinder 19. The top outer wall of the hollow cylinder 19 is equipped with a connecting rod 21 that is inserted into a rectangular hole 17. The hollow cylinder 19 is located directly below the second linear moving component 6. The side wall of the hollow cylinder 19 is rotatably connected to a connecting rod 20 that is coaxial with the flower shaft 18. The bottom outer wall of the workbench 1 is equipped with a drive motor that drives the flower shaft 18 to rotate and a telescopic rod 2 that pushes the hollow cylinder 19 to move.

[0038] During the testing process, once one side of the chip has been tested, the telescopic rod 2 pushes the hollow cylinder 19 upward, and the connecting rod 21 is inserted into the rectangular hole 17. The drive motor drives the hollow cylinder 19 to rotate, and the hollow cylinder 19 drives the worm gear 16 to rotate. Through the transmission of the worm gear 16 and the worm wheel 15, the fixed rod 10 rotates 180 degrees, causing the chip to flip over and the other side of the chip to be tested. Then, the telescopic rod 2 drives the hollow cylinder 19 downward, and the connecting rod 21 disengages from the rectangular hole 17, waiting for the next chip to be flipped.

[0039] By incorporating a flower shaft 18, a hollow cylinder 19, a connecting rod 20, and a connecting insert 21, it can be used to drive the chips in multiple clamping slots 9 to flip, reducing the need for a power source.

[0040] Working principle: During testing, the chip to be tested is placed between two clamping plates 11 in a clamping slot 9. The clamping motor 13 is started by controlling the enclosure 2, causing the two worktables 1 to move relative to each other along the fixed rod 10 and the bidirectional lead screw 12. The two clamping plates 11 clamp the chip. Then, the rotary motor drives the rotating disk 8 to rotate at a certain angle, so that the chip to be tested enters the enclosure 2 and moves to below the visual inspection camera 7. The supplementary light is lit for illumination. The first linear movement component 4, the telescopic rod 5, and the second linear movement component 6 adjust the position of the visual inspection camera 7 so that the visual inspection camera 7 can obtain better imaging effect. The enclosure 2 covers the chip, creating a stable optical inspection ring. The system is designed to prevent interference from external light and allows subsequent chips to be clamped into other clamping slots 9. After one side of the chip is inspected, the telescopic rod 2 pushes the hollow cylinder 19 upward, and the connecting rod 21 is inserted into the rectangular hole 17. The drive motor drives the hollow cylinder 19 to rotate, which in turn drives the worm gear 16 to rotate. Through the transmission of the worm gear 16 and the worm wheel 15, the fixed rod 10 is rotated 180 degrees, causing the chip to flip over and inspect the other side of the chip. Then, the telescopic rod 2 drives the hollow cylinder 19 downward, and the connecting rod 21 disengages from the rectangular hole 17, waiting for the next chip to flip. After one chip is inspected, the subsequent chips to be inspected are moved to the area below the visual inspection camera 7 for visual inspection, thus achieving continuous inspection.

[0041] 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.
