[0027] The embodiment is to provide a kind of power module carrying compatible device, as shown in Figure Figure 1 Test platform 1 has test site 11, processing platform 2 is located in the side of test platform 1 and has standby material site 21 and water removal site 22, each carrier 4 is used to carry different power module 7, manipulator 3 is located in the side of test platform 1 and processing platform 2, manipulator 3 is used to clamp any one carrier 4 along X direction and drive carrier 4 to move between test site 11, standby material site 21 and water removal site 22, the size of each carrier 4 along X direction is consistent.

[0028] The power module carrying compatible device provided in the above embodiment works, manipulator 3 places carrier 4 with power module 7 in test site 11 for testing, after testing, manipulator 3 grabs carrier 4 of test site 11 and carries carrier 4 to standby material site 21, after waiting time ends, manipulator 3 carries carrier 4 on standby material site 21 to water removal site 22, and carries out water removal operation.When different power modules 7 need to be tested, different carriers 4 can be replaced, without again optimizing the structure of manipulator 3, it is convenient and simple to operate.

[0029] The power module carrying compatible device provided in the above embodiment, different carriers 4 can place different power modules 7, manipulator 3 clamps each power module 7 along X direction and carries without directly carrying power module 7, eliminates the influence of different shape features of power module 7 on manipulator 3, since the size of each carrier along X direction is consistent, the same set of power module carrying compatible device only needs to replace different carriers 4 to adapt to different power modules 7, saves the research and development time of lossless aging automatic test equipment and the test cost of testing multiple power modules.

[0030] It should be noted that the power module conveying and compatible device is usually used for batch detection of the same type of power module 7, at this time the same carrier 4 can be used to carry the above-mentioned type of power module 7, and at least one power module 7 can be carried on each carrier 4; when detecting the next type of power module 7, the power module 7 can be placed on the carrier 4 corresponding thereto, and at least one power module 7 can be carried on each carrier 4, and the manipulator 3 clamps the carrier 4 to realize detection of the above-mentioned type of power module 7.

[0031] The test platform 1 can include a waterway plate and a support block 12 for supporting the waterway plate, the waterway plate is concave with a cooling cavity, and the cooling cavity contains circulating cooling water. An external water supply device such as a water heater can input cold water into the cooling cavity, which flows into the cooling cavity through the internal waterway of the waterway plate, carries away the heat of the power module 7 during the no-load aging test, and then is discharged from the internal waterway of the waterway plate.

[0032] The processing platform 2 includes a material waiting and blowing water sealing box 23 and a material waiting and blowing water integrated plate 24. The top of the material waiting and blowing water sealing box 23 is open, and the bottom of the power module 7 is cleaned.

[0033] In an optional embodiment, as shown in Figure 2 The test position 11, the material waiting position 21 and the water removing position 22 are concave with a avoiding slot 5 for the manipulator 3 to extend in to take and place the carriers 4.

[0034] When the manipulator 3 places the carrier 4 on the test position 11, the material waiting position 21 and the water removing position 22, the manipulator 3 can extend into the avoiding slot 5 to avoid interference between the manipulator 3 and the test position 11, the material waiting position 21 and the water removing position 22 respectively; when it is needed to take away the carrier 4 on the test position 11, the material waiting position 21 and the water removing position 22, the manipulator 3 can extend into the avoiding slot 5 to support the bottom of the carrier 4, so as to facilitate stable grabbing of the carrier 4.

[0035] In an optional embodiment, as shown in Figure 2 The end of the avoiding slot 5 corresponding to the edge of the carrier 4 includes a guide part 51, and the opening of the guide part 51 gradually decreases along the direction in which the manipulator 3 extends horizontally.

[0036] The above-mentioned guide part 51 can guide the manipulator 3, which is conducive to accurately aligning the avoiding slot 5 when the manipulator 3 picks up the carrier 4.

[0037] In an optional implementation, in order to ensure that the carrier 4 can be stably positioned at the test position 11, the waiting position 21 and the dewatering position 22, a limiting structure is provided between the carrier 4 and each of the above-mentioned work positions to limit the position of the carrier 4.

[0038] The limiting structure can take many forms, such as guide grooves and guide rails set between the carrier 4 and each workstation, or positioning pins and positioning holes set between the carrier 4 and each workstation.

[0039] In an optional embodiment, the test position 11, the waiting position 21 and the dewatering position 22 are all provided with a first positioning pin 6, and each carrier 4 is provided with a first positioning hole 41 for inserting the first positioning pin 6; or each carrier 4 is provided with a first positioning pin 6, and the test position 11, the waiting position 21 and the dewatering position 22 are all provided with a first positioning hole 41 for inserting the first positioning pin 6.

[0040] by Figure 2 For example, the test position 11, the waiting position 21 and the dewatering position 22 are all provided with two first positioning pins 6. The two first positioning pins 6 are diagonally distributed in the test position 11, the waiting position 21 and the dewatering position 22. Correspondingly, each carrier 4 is provided with two first positioning holes 41 for inserting the two first positioning pins 6 one by one.

[0041] When placing the carrier 4, the robotic arm 3 aligns the two first positioning holes 41 on the carrier 4 with the two first positioning pins 6, and then moves the carrier 4 downward, so that the two first positioning pins 6 are respectively inserted into the two first positioning holes 41, thereby positioning the carrier 4. Since the two first positioning pins 6 are diagonally distributed, the position of the carrier 4 relative to the test position 11 can be limited along the X and Y directions, ensuring that the carrier 4 can be tested more stably.

[0042] In alternative implementations, such as Figure 2 As shown, each vehicle 4 is provided with a platform 42 for accommodating the power module 7.

[0043] The aforementioned platform 42 can limit the position of the power module 7 relative to the carrier 4 to a certain extent, while also facilitating the immersion of the power module 7 in the coolant inside the test platform 1, thereby dissipating heat from the power module 7 during testing.

[0045] In an optional embodiment, on each carrier 4, the shape of the sink 42 is profiled according to the characteristics of different power modules 7, for example, the shape of the sink 42 is matched with the shape of the carried power module 7, so that each carrier 4 can more targetedly limit and support different power modules 7.

[0046] In an optional embodiment, as shown in Figure 2 At least one carrier 4 is provided with a second positioning pin 43 for limiting the position of the carried power module 7 relative to the carrier 4.

[0047] The second positioning pin 43 can be inserted into the second positioning hole on the power module 7, and the second positioning pin 43 can limit the position of the power module 7 relative to the carrier 4, so as to ensure that the power module 7 is more stably installed on the carrier 4.

[0050] In the above-mentioned jaw assembly 32, the jaw body 321 can extend into or away from the avoiding groove 5 to take and place each carrier 4, which is convenient for taking and placing the carrier 4.

[0051] Specifically, as shown in Figure 3 The surface of the jaw body 321 for clamping the carrier 4 is provided with a buffer layer 322.

[0052] When clamping the carrier 4, the buffer layer 322 can use its elasticity to ensure that the jaw body 321 more stably clamps the carrier 4, effectively avoiding the phenomenon of the carrier 4 falling off.

In use, the two gripper bodies 321 are driven to move in the same direction and in the opposite direction through the movement of the telescopic rods in the X direction, so as to realize the taking and placing of the carrier 4.

[0055] As shown in Figure 3 each of the gripper bodies 321 can be further provided with a pair of sensors 324 for detecting whether there is a power module 7 on the carrier 4 carried by the gripper body 321.

[0056] In an alternative embodiment, the driving mechanism 31 is used to drive the gripper assembly 32 to move in the Z direction and the Y direction. It can be understood that the above-mentioned Z direction is the vertical direction, and the above-mentioned Y direction is the horizontal direction perpendicular to the X direction.
