[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0073] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0074] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0075] The present invention proposes a device for high-temperature and normal-temperature testing of DBC. The device for high-temperature and normal-temperature testing of DBC is compatible with a variety of different testing machines, realizing different detection modes for different batches of the same DBC product, breaking the limitation of the traditional single matching testing method. One detection line can complete different detection modes of different batches of DBC products, without setting up multiple detection lines, greatly reducing the detection cost and floor space. The detection process is flexible and changeable, fully meeting the various testing process requirements of different batches of DBC products.

[0076] Specifically, in one embodiment of the invention, Figure 1As shown, the device for high-temperature and normal-temperature testing of DBC comprises a mounting plate 1, a mounting plate 2 40, a loading module, a heating transfer module, a testing module, and a material sorting module, wherein the loading module, the heating transfer module, the testing module, and the material sorting module are arranged on the mounting plate 1 and the mounting plate 2 40; during operation, the heating transfer module picks up the DBC liner conveyed by the loading module, heats the DBC liner, and then conveys the heated DBC liner to the testing module, which performs high-temperature dynamic testing, high-temperature static testing, or high-temperature dynamic and normal-temperature static testing on the DBC liner. After completion, the test module sends the DBC liner to the material unloading and sorting module, which sorts and unloads the DBC liner. Since the test module has the functions of high-temperature dynamic, high-temperature static testing or high-temperature dynamic and normal temperature static testing, different detection modes for different batches of the same DBC product are realized, breaking the limitations of the traditional single supporting testing method. One detection line can complete different detection modes of different batches of DBC products. There is no need to set up multiple detection lines, which greatly reduces the detection cost and floor space. The detection process is flexible and changeable, which fully meets the various testing process requirements of different batches of DBC products.

After all the DBC liners placed on the pallet 4 are scanned, the lifting device 2 5 is reset, and the conveyor line 2 continues to convey the pallet 4, and is finally stopped by the lifting device 3, and then the heating transfer module removes the DBC liners on the pallet 4. After all the DBC liners are removed, the lifting device 3 is reset, and the conveyor line 2 sends the empty pallet 4 to the conveyor line 4 30, as shown in FIG. Figure 1 shown.

[0079] In this embodiment, if Figure 2-Figure 4 As shown, the loading module also includes a lifting device four 11, which is located in the conveyor line 2 and fixedly connected to the mounting plate 1.

After the conveyor line 3 8 can transport the pallet 4 thereon to the conveyor line 2 6, the lifting device 3 7 drives the conveyor line 2 6 to descend and place the pallet 4 on the conveyor line 2, and then the pallet 4 is stopped by the lifting device 2 5. After the lifting device 2 5 is reset, the pallet 4 is sent away by the conveyor line 2, and the DBC liner that needs to be retested is placed in each acupoint 14 on the pallet 4, and then the pallet 4 is loaded from the conveyor line 3 8.

Whether cooling is required will be introduced in detail later.

[0087] In this embodiment, if Figure 5-Figure 8 As shown, the working process of the test module is as follows: the material transfer mechanism 3 19 transfers the DBC liner on the storage seat 18 at the material taking position of the test module to the storage seat 2 237 of the rotating test device 23, and then the rotating device 234 drives the storage seat 237 to rotate 180 degrees, so that the DBC liner on the storage seat 237 faces downward and the pressure plate 238 faces upward, and then the rotating device 1 231 drives the storage seat 237 to rotate and move to just below the pressure column 253 of the clamping device 1 25.
