[0026] When performing wafer inspection, the tester needs to be flipped over and placed on top of the probe station and docked with the probe station. As the types of wafer chips increase, the types of testers also increase. Different types of testers have different weights. How to ensure that testers of different weights can be flipped onto the probe station becomes a technical problem that needs to be solved.

[0027] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic diagram of a flipping mechanism provided in an embodiment of the present application, Figure 2 It is a structural schematic diagram of a flipping device and a test machine simulation device provided in an embodiment of the present application.

[0029] The flipping mechanism 100 includes a test machine simulation device 10, a connection simulation device 20 and a flipping device 30. The test machine simulation device 10 includes a shell component 11 and a first counterweight component 12. The shell component 11 includes a cubic frame 111 and a first bearing plate 112. The cubic frame 111 encloses a receiving space. The first bearing plate 112 is arranged on the cubic frame 111 and in the receiving space, and the first bearing plate 112 is fixed to the bottom of the cubic frame 111. Optionally, the fixed connection method of the first bearing plate 112 and the cubic frame 111 includes but is not limited to a threaded connection. The first bearing plate 112 is used to carry the first counterweight component 12. When the test machine simulation device flips over to the top of the test machine, the first bearing plate 112 is parallel to the horizontal ground, so that the bottom surface of the first counterweight component 12 is parallel to the horizontal ground, thereby improving the horizontality of the first counterweight component 12 and avoiding the imbalance of the first counterweight component 12 and causing excessive stress in a certain part.

[0030] The first counterweight assembly 12 is disposed on the first bearing plate 112, and the first counterweight assembly 12 includes at least one first counterweight block 121 and at least one second counterweight block 122. In other words, the number of the first counterweight blocks 121 can be multiple, and optionally, the number of the first counterweight blocks 121 can be one, or two, or three, or four, or five, or six, or more than six, and the present application does not limit this. Similarly, the number of the second counterweight blocks 122 can be multiple, and optionally, the number of the second counterweight blocks 122 can be one, or two, or three, or four, or five, or six, or more than six, and the present application does not limit this.

The connecting device is arranged at the bottom of the test machine, and the connecting device is used to connect the test machine and the probe station 40. The connecting simulation device 20 can be used to simulate the connecting device. The connecting simulation device 20 is arranged at the bottom of the test machine simulation device 10 and is used to connect the test machine simulation device 10 and the probe station 40. The damage condition and structural condition of the connecting simulation device 20 can reflect the damage condition and structural condition of the connecting device when the test machine of this weight is flipped, thereby avoiding the damage of the connecting device when the flipping device 30 directly flips the test machine.

The weight of the first counterweight assembly 12 can be adjusted by adjusting the number of the first counterweight block 121 and the second counterweight block 122, and then the weight of the test machine simulation device 10 can be adjusted, so that the test machine simulation device 10 simulates test machines of different weights, and then the flipping mechanism 100 can verify the flipping effect of test machines of different weights. In addition, the damage condition and structural condition of the connection simulation device 20 can reflect the damage condition and structural condition of the connection device when the test machine of this weight is flipped, so as to avoid damage to the connection device when the flipping device 30 directly flips the test machine.

[0036] Moreover, by means of the damage condition and structural condition of the connection simulation device 20 in the flipping mechanism 100, the flipping power, flipping speed and other methods of the flipping device 30 can be adjusted to ensure that the connection simulation device 20 maintains normal working condition when the flipping mechanism 100 flips the test machine simulation device 10 next time, so as to avoid damage to the test machine and the connection device during the actual flipping of the test machine.

[0037] Furthermore, by adjusting the number of the first counterweight block 121 and the second counterweight block 122 in the first counterweight module, the weight of the test machine simulation device 10 can be adjusted, so that the flipping mechanism 100 can also perform flipping verification on test machines of different weights to ensure that the test machines of different weights can be stably flipped onto the probe station 40.
