[0036] Figure 1 is a schematic structural diagram of a chip tester 100 according to an embodiment of the present utility model. Figure 2 is Figure 1 a schematic enlarged view of part A shown. Figure 3 is Figure 1 a schematic structural diagram of the plugging and unplugging mechanism 10 of the chip tester 100 shown at an angle. Figure 4 is Figure 1Schematic structural diagram of the plugging and unplugging mechanism 10 of the chip tester 100 shown from another angle. As Figures 1 to 4 shown, in a specific embodiment, the chip tester 100 includes a box body 40, at least one first connector 31 located inside the box body 40, at least one test drawer 20 that can be inserted into the box body 40, and at least one plugging and unplugging mechanism 10. The test drawer 20 has a second connector 21. A test board 30 is installed inside the box body 40, and at least one first connector 31 is installed on each test board 30. The plugging and unplugging mechanism 10 includes a clamping member 18 and a driving assembly 11. The clamping member 18 is installed on the test drawer 20. The driving assembly 11 is installed inside the box body 40. The driving assembly 11 is configured to be clamped with the clamping member 18 on the corresponding test drawer 20 when the test drawer 20 is inserted into the box body 40, and is controlled to drive the test drawer 20 to move towards the inner side of the box body 40, so that the second connector 21 of the test drawer 20 is connected to the corresponding first connector 31. Here, each first connector 31 and each second connector 21 have 200 pins respectively.

[0037] In this embodiment, by installing the clamping member 18 on the test drawer 20 and arranging the driving assembly 11 inside the box body 40, the driving assembly 11 and the clamping member 18 are used to realize the automatic tightening of the first connector 31 on the test drawer 20 and the second connector 21 of the test board 30, without the need for manual tightening, and there is no gap after the first connector 31 and the second connector 21 are tightened, improving the connection stability between the first connector 31 and the second connector 21.

[0038] In this embodiment, the driving assembly 11 is also configured to be controlled to drive the test drawer 20 to move towards the outer side of the box body 40, so that the second connector 21 of the test drawer 20 is separated from the corresponding first connector 31. It can be understood that the driving assembly 11 can not only realize the automatic tightening of the first connector 31 and the second connector 21, but also realize the automatic separation of the first connector 31 and the second connector 21, without the need for manual plugging and unplugging, saving manpower, and the first connector 31 and the second connector 21 can be more stably connected through the automatic plugging and unplugging method, thereby improving the test stability.

[0039] In this embodiment, the box body 40 has at least one installation position 43 for the test drawer 20 to be inserted. Each installation position 43 has an opening 41, and the test drawer 20 can be inserted from the opening 41 and installed at the installation position 43. Here, the number of installation positions 43 can be designed according to the size of the box body 40.

[0040] In some embodiments, the driving assembly 11 includes a cylinder 12 and a linkage 14. The cylinder 12 is installed on one side of the installation position 43, and the cylinder 12 has a piston rod 121 that can extend outward from the outside of the box body 40. One end of the linkage 14 is movably connected to the end of the piston rod 121, and the other end has a card slot 141 that abuts against the clamping member 18. In other embodiments, a gear-rack mechanism can also be used to drive the linkage 14 to rotate. Here, when the piston rod 121 of the cylinder 12 extends, it can drive the linkage 14 to rotate, so that the linkage 14 drives the test drawer 20 to move into the box body 40 through the clamping member 18, so that the first connector 31 and the second connector 21 are plugged tightly. When the piston rod 121 of the cylinder 12 retracts, it can drive the linkage 14 to rotate in the reverse direction, separating the first connector 31 from the second connector 21.

[0041] In some embodiments, the driving assembly 11 further includes a first connecting member 13 and a roller 16. The first connecting member 13 is installed at the end of the piston rod 121, and the first connecting member 13 has a sliding groove 15. The roller 16 is connected to the end of the linkage 14 away from the card slot 141 and is located in the sliding groove 15. The roller 16 is configured to slide along the sliding groove 15 when the first connecting member 13 moves with the piston rod 121, so as to drive the linkage 14 to rotate, so that the linkage 14 drives the test drawer 20 to move. That is to say, when the piston rod 121 of the cylinder 12 extends, the first connecting member 13 moves outward from the box body 40 with the piston rod 121, causing the roller 16 to roll in the sliding groove 15 and driving the linkage 14 to rotate. Here, the roller 16 can be a component with a circular outer circumference such as a bearing.

[0042] In some embodiments, the clamping member 18 is installed at the bottom of the test drawer 20 and is L-shaped. At least a part of one side of the clamping member 18 is located in the card slot 141, see Figure 4 . In this embodiment, the clamping member 18 has a first part extending along the length direction of the test drawer 20 and a second part extending along the width direction of the test drawer 20. The second part of the clamping member 18 abuts against the card slot 141 of the linkage 14. In other embodiments, the shape of the clamping member 18 can also be designed according to specific design requirements.

[0043] In some embodiments, first protrusions 144 and second protrusions 143 are respectively provided at both side edges of the card slot 141. The first protrusions 144 are located on the side of the second protrusions 143 closer to the inside of the box body 40. The clamping member 18 is configured to abut against the first protrusions 144 of the corresponding card slot 141 when the test drawer 20 is inserted into the box body 40, and abut against the second protrusions 143 of the card slot 141 when the linkage member 14 rotates, so as to drive the test drawer 20 to move towards the inner side of the box body 40 when the linkage member 14 continues to rotate. Here, when the test drawer 20 is inserted into the corresponding installation position 43 from the opening 41 of the box body 40 until the second part of the clamping member 18 abuts against the first protrusions 144 of the linkage member 14, the movement stops. This is because the linkage member 14 will not rotate when there is air pressure in the air cylinder 12, so the test drawer 20 will not move further. At this time, if the piston rod 121 of the air cylinder 12 extends, it will push the linkage member 14 to rotate, so that the second protrusions 143 of the linkage member 14 abut against the clamping member 18. After the linkage member 14 continues to rotate, it will push the test drawer 20 to move towards the inside of the box body 40 until the second connector 21 is tightly inserted into the corresponding first connector 31. When the clamping member 18 abuts against the first protrusions 144, there will be a gap between the first end face 22 of the test drawer 20 and the second end face 42 of the box body 40. After the first connector 31 and the second connector 21 are tightly inserted, the gap will disappear.

[0044] In this embodiment, when it is necessary to pull out the test drawer 20 from the box body 40, the piston rod 121 of the air cylinder 12 is controlled to retract, thereby driving the linkage member 14 to rotate in the reverse direction, so that the first protrusions 144 abut against the clamping member 18, and the test drawer 20 is pushed to move towards the outside of the box body 40, thereby realizing the separation of the first connector 31 and the second connector 21.

[0045] In some embodiments, the drive assembly 11 further includes a second connecting member 17. The second connecting member 17 is installed at the bottom inside the box body 40 and is rotatably connected to the linkage member 14. The air cylinder 12 is installed on the second connecting member 17. Here, the second connecting member 17 is in a plate shape.

[0046] In some embodiments, the second connecting member 17 has an extension portion 171 extending towards the outside of the box body 40. The end of the extension portion 171 is rotatably connected to the linkage member 14. Specifically, the connection point between the extension portion 171 and the linkage member 14 is located on the side of the card slot 141 closer to the central position of the linkage member 14.

[0047] In some embodiments, the linkage member 14 further has a weight reduction hole 142. The weight reduction hole 142 is located at the central position of the linkage member 14, which can reduce the weight of the linkage member 14.

[0048] This embodiment also provides a chip tester 100, and the chip tester 100 includes the above-mentioned plugging and unplugging mechanism 10. Preferably, the chip tester 100 is a COC aging test device for COC (Chip on Carrier) devices. For the plugging and unplugging mechanism 10, details are not described one by one here.

[0049] Up to this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
