[0025] The first end 211 is inserted into the transverse groove 14, and the second end 212 is received in the rotation groove 11 and corresponds to the transverse opening 13, so that the connecting rod 21 is in a received state, the second end 212 passes through the transverse opening 13, the first end 211 is pulled out of the transverse groove 14 and placed in the rotation groove 11, so that the connecting rod 21 is switched to an intermediate state, and the second end 212 rotates around the first end 211 to correspond to the vertical opening 12, so that the connecting rod 21 is switched to a suspended state;

[0026] An air inlet 15 and a plurality of air outlets 16 are respectively provided on the bottom and top surfaces of the air outlet module 1. The air inlet 15 is connected to the output end of the gas delivery device. When the connecting rod 21 is in a suspended state, the connecting block 22 of the two suspension members 2 is magnetically connected to the shell of the chip tester. The plurality of air outlets 16 are arranged corresponding to the test boards on the shell. An air guide channel 17 connected to the air inlet 15 and the air outlet 16 respectively is provided in the air outlet module 1. The air guide channel 17 is used to guide the cooling gas input through the air inlet 15 to each air outlet 16 for output.

[0027] The present invention is provided with two suspension members 2 to fix the air outlet module 1 to the housing of the chip tester to cool the test board. The two ends of the air outlet module 1 are provided with a rotation groove 11 and a transverse groove 14. The suspension member 2 includes a connecting rod 21 and a connecting block 22. When the connecting rod 21 is in the storage state, the first end 211 of the connecting rod 21 is inserted into the transverse groove 14, and the second end 212 of the connecting rod 21 is received in the rotation groove 11 and fixedly connected to the connecting block 22. The first end 211 is pulled out from the transverse groove 14, and the second end 212 is rotated around the first end 211 to make the connecting rod 21 The rod 21 is switched to a hanging state, and the connecting block 22 of the two hanging parts 2 is magnetically connected to the shell of the chip tester, so that the multiple air outlets 16 on the top surface of the air outlet module 1 are arranged corresponding to the test board on the shell, and the air inlet 15 on the bottom surface of the air outlet module 1 is connected to the gas delivery device. The air outlet module 1 guides the cooling gas input through the air inlet 15 to each air outlet 16 for output through the air guide channel 17, so as to achieve cooling of the test board, thereby avoiding it from being in an overheated state for a long time due to high-temperature testing, which is beneficial to reducing the occurrence of low yield of chip testing and improving chip testing efficiency.

[0028] See also Figures 1 to 4 The side wall of the transverse groove 14 is provided with a guide groove 18, and the guide groove 18 extends laterally to the side wall of the rotating groove 11. The first end 211 is provided with a pivot portion 213 inserted into the guide groove 18. When the first end 211 is inserted into or pulled out of the transverse groove 14, the pivot portion 213 moves laterally along the guide groove 18. When the second end 212 rotates around the first end 211, the pivot portion 213 forms a rotating pivot axis of the connecting rod 21.

[0029] Specifically, in this embodiment, the transverse channels 14 provided at both ends of the air outlet module 1 communicate with each other to form a single channel, and the guiding channels 18 provided in the two transverse channels 14 also communicate with each other. However, this is not limited thereto. The side of the guiding channel 18 that communicates with the rotating channel 11 forms a rotating pivot hole. When the first end 211 is withdrawn from the transverse channel 14 and placed in the rotating channel 11, the pivoting portion 213 and the guiding channel 18 form a pivoting fit, achieving the effect of the second end 212 rotating around the first end 211, and the suspension member 2 switches from the intermediate state to the suspended state.

[0030] Refer to Figures 1 to 4 , a first magnetic member 101 is provided on the side wall of the rotating channel 11. When the connecting rod 21 switches to the suspended state, the first magnetic member 101 is magnetically connected to the first end 211, which is beneficial for keeping the connecting rod 21 upright and improving the stability of the magnetic adsorption of the connecting block 22 to the bottom of the testing machine platform.

[0031] Refer to Figures 1 to 4 , second magnetic members 102 are provided on both end faces of the air outlet module 1. When the connecting rod 21 switches to the storage state, the second magnetic members 102 are magnetically connected to the connecting block 22, which is beneficial for preventing the first end 211 and the second end 212 of the connecting rod 21 from sliding out of the transverse channel 14 and the rotating channel 11 in the storage state and maintaining the connection stability of the connecting rod 21 in the storage state.

[0032] Specifically, in this embodiment, the first magnetic member 101, the second magnetic member 102, and the connecting block 22 are magnets, which is convenient for the installation and disassembly of the cooling device. However, this is not limited thereto. When cooling is required, the connecting block 22 of the two suspension members 2 is separated from the second magnetic member 102, and then the two connecting rods 21 are withdrawn outward from the transverse channels 14 at both ends of the air outlet module 1. Then, the two connecting rods 21 are folded upward and magnetically adsorbed and fixed to the first magnetic member 101, so that the two connecting rods 21 are kept upright, and the two suspension members 2 switch to the suspended state. Then, the connecting block 22 is adsorbed to the bottom of the testing machine platform by magnetic attraction, so that the air outlet module 1 can be suspended below the testing board to be cooled at the bottom of the machine platform, and the multiple air outlets 16 of the air outlet module 1 are correspondingly arranged with the testing board.

[0033] Refer to Figures 1 to 4 , the connecting rod 21 includes a rod body 214 and at least one rod barrel 215. One end of the rod body 214 is inserted into the rod barrel 215, and the other end forms a telescopic second end 212. The end of the rod barrel 215 away from the rod body 214 forms a first end 211.

[0034] Specifically, in this embodiment, the rod body 214 and the rod barrel 215 cooperate to enable the connecting rod 21 to achieve the effect of a telescopic rod. By pulling out or inserting the rod body 214 from the rod barrel 215, the relative position between the rod body 214 and the rod barrel 215 is adjusted to change the distance between the air outlet module 1 and the test board, thereby changing the cooling distance and cooling effect of the air outlet module 1.

[0035] Refer to Figures 1 to 4 , two rotating grooves 11 are arranged side by side along the longitudinal direction on the air outlet module 1, two connecting rods 21 are arranged side by side along the longitudinal direction on the suspension member 2, and the two connecting rods 21 are correspondingly connected to the two rotating grooves 11, effectively improving the connection stability of the suspension member 2 and ensuring the flexibility of the suspension member 2 to switch between the suspended state and the stored state.

[0036] Specifically, in this embodiment, the air outlet module 1 includes an air outlet member 103 and two housing members 104. The two housing members 104 are respectively arranged on both sides of the air outlet member 103 along the longitudinal direction. The air inlet 15, multiple air outlets 16, and the air guide channel 17 are formed on the air outlet member 103, and the rotating groove 11 and the transverse channel 14 are formed on the housing member 104, but are not limited thereto.

[0037] Refer to Figures 1 to 4 , the air outlet module 1 is further provided with a control valve 105 and a quick connector 106. Both ends of the control valve 105 are respectively connected to the air inlet 15 and the quick connector 106. The end of the quick connector 106 away from the control valve 105 is connected to the quick connection air pipe of the gas transmission device. The control valve 105 is used to control the flow rate of the cooling gas output by the gas transmission device through the quick connector 106 into the air inlet 15.

[0038] Further, the cooling gas is compressed air.

[0039] Specifically, in this embodiment, the quick connector 106 is a 20PM quick connector, which is directly connected to the quick connection air pipe of the chip tester machine platform, so that the compressed air of the machine platform quick connection air pipe is connected to the air outlet module 1 through the air inlet 15, but is not limited thereto.

[0040] Specifically, in this embodiment, the control valve 105 is a throttle valve. The flow rate of the compressed air entering the air inlet 15 is adjusted through the control valve 105 to change the air output volume of the air outlet 16, but is not limited thereto.

[0041] Specifically, in this embodiment, the air outlet module 1 is in a cuboid shape, and multiple air outlets 16 are arranged at intervals along the transverse direction on the top surface of the air outlet module 1. When the suspension members 2 arranged at both ends thereof straddle the lower part of the test board, its cooling range can cover all the test boards, but is not limited thereto. After installing the cooling device at the bottom of the test machine platform, opening the control valve 105 can start cooling the test board.

[0042] The above-disclosed are only the preferred embodiments of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
