DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the implementation mode of the utility model will be further described below in conjunction with the accompanying drawings.

[0019] Please refer to Figures 1 to 3 The utility model discloses an automatic detection device for a contact-type power module, comprising a detection platform 1, a conveyor belt module, a detector 6 and a lifting contact assembly.

[0020] The inspection platform 1 is a rounded rectangular flat plate. The conveyor belt module is located on the inspection platform. The conveyor belt module includes a conveyor belt 2 and a driving component, wherein the driving component is used to drive the conveyor belt 2 to operate. The conveyor belt 2 is made of a material with a certain thickness and elasticity. Specifically, the driving component includes a driving motor 3 and two tensioning shafts 31. Rotating support seats 32 are provided at both ends of the two tensioning shafts 31. The rotating support seats 32 are fixed on the inspection platform 1. The tensioning shafts 31 can be rotatably arranged on the inspection platform 1 through the rotating support seats 32. The two tensioning shafts 31 are located in the conveyor belt and tension the conveyor belt 2. One of the tensioning shafts 31 can be rotatably connected to the driving motor 3. The driving motor 3 is also fixed on the inspection platform 1. The driving motor 3 is a stepping motor. The driving motor 3 drives the tensioning shaft 31 connected thereto to rotate, thereby driving the conveyor belt 2 to operate.

[0021] The surface of the conveyor belt 2 is provided with a plurality of limiting grooves 21 , and the distances between adjacent limiting grooves 21 are equal; the power module 4 to be detected is located in the limiting grooves 21 .

[0022] The lifting contact assembly includes a bracket 51, a lifting cylinder 5 and at least two conductive feeler rods 52. In this embodiment, there are two conductive feeler rods 52. The bracket 21 includes a fixed base, a support rod and a mounting plate. The fixed base is fixed on the detection platform 1, the lower end of the support rod is fixed on the fixed base, the mounting plate is connected to the upper end of the support rod, the lifting cylinder 5 is fixed above the mounting plate, and the lifting cylinder telescopes through the mounting plate. A lifting plate 53 is provided at the lower end of the telescopic shaft of the lifting cylinder 5. The lower end of the conductive feeler rod 52 passes through the lifting plate 53 and extends to the bottom of the lifting plate 53. The upper ends of the conductive feeler rods 52 are connected to the detector 6 through the detection wire 54. Specifically, a mounting hole is provided on the lifting plate 53. A locking nut is provided at the lower end of the telescopic shaft of the lifting cylinder 5. The telescopic shaft of the lifting cylinder 5 passes through the mounting hole. The locking nut fixes the lifting plate 53 to the lower end of the telescopic shaft. The lifting cylinder 5 is located above the conveyor belt, and is used to drive the conductive feeler rod 52 to descend, so that the lower end of the conductive feeler rod 52 contacts the contact 41 on the power module 4, thereby electrically connecting the detector 6 to the power module 4 to be detected, so that the detector 6 detects the electrical parameters of the power module 4.

[0023] Preferably, each conductive touch rod 52 is provided with an elastic bending portion at the lower end, and the bending portion is a metal sheet structure and a horizontal V-shape, so that the bending portion has elasticity in the vertical direction, so that the lower end of the conductive touch rod 52 can be in close contact with the detection contact 41 of the power module 4, thereby preventing poor contact between the two and improving the detection accuracy.

[0024] Preferably, the automatic detection device also includes a controller 7, which is connected to the drive motor, the lifting cylinder and the detector 6. The controller 7 is used to control the drive motor to drive the conveyor belt 2 to operate, and the drive motor stops for a period of time after each rotation of the same angle. At this time, the controller 7 controls the lifting cylinder to extend the telescopic shaft so that the conductive touch rod 52 contacts the detection contact 41 of the power module 4, and then the controller 7 controls the detector 6 to detect the electrical parameters of the power module 4 connected thereto.

[0026] The working process of the contact-type power module automatic detection device of the utility model is as follows: the mechanical arm (mechanical arms for loading and unloading are provided at both ends of the automatic detection device) places the power modules 4 to be detected in the limit grooves 21 of the conveyor belt 2 one by one, and the driving motor 3 drives the conveyor belt 2 to operate under the control of the controller 7. The driving motor 3 stops for a period of time after rotating the same angle each time, so that the power modules 4 on the conveyor belt 2 move the same distance each time (the distance is equal to the distance between adjacent limit grooves), so that the power modules 4 to be detected are moved one by one to the bottom of the lifting cylinder; then the lifting cylinder 5 drives the two conductive contact rods 52 to descend, so that the lower ends of the conductive contact rods 52 elastically press the detection contacts 41 of the power module 4, so that the detector 6 is connected with the power module 4 to be detected, and the detector 6 detects the electrical parameters of the power module 4 and displays the detection results, thereby completing the detection of the power module 4, repeating the above process, the detection device can automatically and continuously complete the detection of all the power modules 4 to be detected.
