[0023] The detection personnel prepares the IGBT modules to be detected. When the modules are in the initial position, the detection personnel controls the first electric slide rail 6 on one side to make the placing chassis 7 on it sink to the lowest end. At the same time, the detection personnel stacks several layers of modules to be detected on the cylindrical support at the top of the placing chassis 7 until the modules are stacked to a height that allows the detection personnel to directly take them from the workbench surface 2. Then, the detection personnel controls the first electric slide rail 6 on the other side to make the placing chassis 7 on it rise to the highest end, preparing to place the modules that have been detected. The detection personnel first takes out a layer of modules and places them on the workbench surface 2 for quality inspection. After the quality inspection is completed, the detection personnel places the detected modules on the placing chassis 7 on the other side that is not stacked with modules. At this time, the detection personnel presses the start button 92, which simultaneously controls the movement of the two placing chassis 7 on the first electric slide rail 6. The side that is stacked with undetected modules moves upward, and the side that is stacked with detected modules moves downward. At this time, the detection personnel can continuously perform quality inspection on new undetected modules. When the current modules are all inspected, the detection personnel controls the second electric slide rail 8 to slowly move the driving frame 9 to the rear side of the fixed frame 1. At this time, the connecting rod 71 moves downward along the slope of the driving frame 9. At this time, the two placing chassis 7 on both sides move downward together with the first electric slide rail 6 until the connecting rod 71 slides to the lowest end of the driving frame 9. Then, the second electric slide rail 8 continues to move the driving frame 9 to the rear side of the fixed frame 1. The horizontal rod on the driving frame 9 drives the connecting frame 5 to move backward, and the guide sliding block 4 also moves along the guide slide rail 3. When the connecting frame 5 slides out to a position where it is convenient to take out all the detected modules, the second electric slide rail 8 is turned off. The detection personnel takes out the detected modules and then puts in the undetected modules. Then, the second electric slide rail 8 is started again to move the driving frame 9 forward, pushing the connecting rod 71 forward. When the connecting frame 5 moves forward and returns to the initial position, the guide sliding block 4 moves to the front end of the guide slide rail 3. The driving frame 9 continues to move, pushing the connecting rod 71 upward through the slope on it. The placing chassis 7 rises, and the uppermost modules are located in the square through hole, which is convenient for the detection personnel to perform quality inspection again.

[0024] When the resistance between the guide sliding block 4 and the guide slide rail 3 increases, if the driving frame 9 moves forward to push the connecting rod 71, and the guide sliding block 4 has not reached the front end of the guide slide rail 3, the connecting rod 71 may move upward prematurely due to the slope on the driving frame 9. However, at this time, the connecting frame 5 and the modules are not in the correct position, causing the modules to rise prematurely and possibly collide with the bottom of the workbench surface 2. To solve this problem, a spring 91 is specially designed. When the driving frame 9 moves forward, the spring 91 can effectively assist the movement of the guide sliding block 4, preventing improper rising and potential collision risks caused by increased resistance.

[0025] When the module is put on the placing chassis 7, the limiting block 10 can prevent the module from falling off the placing chassis 7 due to shaking, and the illuminating lamp 12 which is opened to irradiate the workbench surface 2 can effectively provide a clear and bright view for the detection personnel in a relatively dim environment, and the soft pad 13 can also allow the detection personnel to put the arms thereon to alleviate the fatigue of the detection personnel in long-time work.

[0026] The above merely illustrates the embodiments of the present application and is not intended to limit the present application. Any equivalent replacement within the principles of the present application shall be included in the protection scope of the present application. The contents not described in detail in the present application are the prior art known by the technical personnel in the field.
