Description

Technical Field

[0001] This utility model belongs to the field of semiconductor device processing machinery technology, specifically relating to a universal tray for power modules. Background Technology

[0002] In the power module manufacturing process, trays are typically used to carry the power modules between different processes. When the tray reaches the pressing process, in order to ensure pressing efficiency and quality, the tray must be positioned and fixed on the work platform. At the same time, the power modules in the tray also need to be positioned and fixed to assist in achieving high-precision processing of the product.

[0003] The current method of fixing power modules and trays involves installing fixing devices for the power modules and trays at predetermined positions on the work platform. This results in a complex work platform design and inconvenient operation. Furthermore, due to the diverse types and sizes of power modules, the conventional fixing devices on the work platform cannot meet the fixing requirements of power modules of different sizes. The current method involves replacing the entire work platform or all the fixing devices on the platform, which is time-consuming, labor-intensive, and increases equipment complexity and production costs.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0032] Example 1

[0033] Figure 1 A perspective view of the universal tray for power modules proposed in the embodiment; Figure 2 for Figure 1 A top view of the body of the mid-section. (Example) Figure 1 As shown, the universal power module tray in this embodiment includes a tray body 1 and a pressing assembly. The tray body 1 has one or more power module placement areas 2 for placing power modules. In this embodiment, the tray body 1 has two power module placement areas 2, but one or more can be provided as needed.

[0034] There are at least two sets of pressing components, the specific number of which is determined by the number of power module placement areas 2. Each pair of pressing components is installed on both sides of one power module placement area 2.

[0035] The pressing assembly includes a crossbar 4, several mounting blocks 5, and pressure claws 6. The mounting blocks 5 are detachably fixed to the tray body 1. A connecting portion 41 is provided at the bottom of the crossbar 4 along its long side; two or more connecting portions 41 can be provided to make the crossbar 4 rotate more stably. An extension portion 42 is provided at the top of the crossbar 4 facing the power module placement area 2; two or more extension portions 42 can be provided to better press the power module. The connecting portion 41 is hinged to the mounting blocks 5. The length of the extension portion 42 extends above the power module placement area 2. The pressure claws 6 are detachably mounted to the end of the extension portion 42.

[0036] When using the universal power module tray proposed in this embodiment, the power module to be supported is placed in the power module placement area 2. Then, the crossbar 4 is rotated towards one side of the power module placement area 2 until the pressure claws 6 on the crossbar 4 are precisely pressed onto the power module to be supported. When it is necessary to remove the power module fixed on the tray, the crossbar 4 is rotated in the opposite direction to remove the pressure claws 6 from the power module, thus loosening the fixation on the power module. It should be noted that this embodiment uses two power module placement areas 2 and four sets of pressing components as an example. In actual use, the number of components can be flexibly selected according to specific needs.

[0037] Furthermore, such as Figure 2 As shown, in this embodiment, the connecting part 41, the extension part 42 and the crossbar 4 are an integral structure. Both the connecting part 41 and the extension part 42 protrude from the long side of the crossbar 4. This design makes the manufacturing of the crossbar 4 more convenient, improves the overall appearance, simplifies the installation steps of the pressing components, and helps to reduce the manufacturing cost of the equipment.

[0038] Furthermore, Figure 3 for Figure 1 Exploded view of the medium-voltage composite component. (See attached image.) Figure 1 , Figure 3 As shown, in this embodiment, the extension 42 is provided with a second mounting hole 421 and a claw through hole 422 located outside the second mounting hole 421. The claw 6 includes a claw body 61, claw caps 62 disposed at both ends of the claw body 61, and a crimping part 63. The claw caps 62 and the claw body 61 protrude from the claw through hole 422. The claw caps 62 are located on one side of the first surface of the extension 42 and have a gap of a predetermined width between them. The crimping part 63 is located on one side of the second surface of the extension 42 and is engaged with the claw through hole 422. This embodiment, through this design, facilitates the insertion of the claw 6 into the claw through hole 422 of the extension 42 from below, so that the crimping part 63 is engaged with the claw through hole 422, and then a claw connecting plate 8 is inserted into the gap between the claw caps 62 and the extension 42.

[0039] In this embodiment, the pressure claw connecting plate 8 is provided with a first mounting hole 81 and an opening groove 82, wherein the positions of the first mounting hole 81 and the opening groove 82 correspond to the second mounting hole 421 and the pressure claw through hole 422, respectively. The pressure claw connecting plate 8 is fixed to the extension 42 by a locking member passing through the first mounting hole 81 and the second mounting hole 421. The claw cap 62 is snapped into the opening groove 82, and then the pressure claw connecting plate 8 is locked with the locking member. The pressure claw 6 can be detachably installed on the extension 42 with only one locking member, which is convenient to operate, facilitates the maintenance and replacement of the pressure claw 6, and realizes the adjustment of the spacing of the pressure claws 6 in the mounting groove 3 on the same side.

[0040] Furthermore, such as Figure 1 , Figure 3As shown, in this embodiment, a fourth mounting hole 51 is provided on the mounting block 5, and a first mounting arm and a second mounting arm are provided parallel on the same side wall of the mounting block 5. A second pin through hole 52 located on the same axis is provided on the first mounting arm and the second mounting arm. A first pin through hole 411 matching the second pin through hole 52 is provided on the connecting part 41. A pin 71 passing through the first pin through hole 411 and the second pin through hole 52 is provided on the tray. This installation method is convenient, secure, and has a detachable structure, which can meet the needs of disassembly and assembly of the pressing assembly.

[0041] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, the power module placement area 2 is set as a groove, and the side wall of the groove is higher than the bottom plane of the mounting groove 3. With this setting, the power module can be more stably fixed in the tray. The bottom of the groove can also be further opened with a through groove to facilitate the power module being pushed out from the bottom.

[0042] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, the tray body 1 is a plate-shaped structure. The bottom edge of the tray body 1 is provided with several recesses 9 that are lower than the bottom plane and adjacent to the side. The design of the recesses 9 makes it convenient for people to hold the tray.

[0043] Furthermore, as another improvement to this embodiment, in addition to selecting extensions 42 of different lengths according to the size of the power module to be supported in order to better accommodate the fixing of power modules of different lengths, more extensions 42 can also be provided on the crossbar 4. That is, multiple extensions 42 are evenly provided in the long side direction of the crossbar 4, and then clamping claws 6 are installed on the corresponding extensions 42 according to the size of the power module to be supported. Through this design, the fixing of power modules of different widths can be satisfied.

[0044] Furthermore, in this embodiment, the crossbar 4 is driven by a driver mounted on the work platform. The driver can be a conventional power device such as a cylinder or an electric motor.

[0045] Specifically, when a motor is used as the driver, a rotating shaft is set to connect the pin 7. One end of the rotating shaft is rigidly connected to the pin 7 through a connecting structure such as a sleeve, and the other end of the rotating shaft is connected to the output end of the motor. The rotating shaft rotates forward or backward under the drive of the motor, so as to drive the crossbar 4 to fold to one side of the power module placement area 2 or to the side away from the power module placement area 2, thereby realizing the fixing or loosening operation of the power component it carries.

[0046] Specifically, when a cylinder is used as the actuator, a connecting seat can be provided on the middle outer wall of the crossbar 4. The cylinder includes a cylinder body, a piston, and a piston rod. The piston is located in the cylinder body, one end of the piston rod is connected to the piston, and the other end extends out of the cylinder body and is fixedly connected to the connecting seat of the crossbar 4. Then, the crossbar 4 is driven by the cylinder to fold towards one side of the power module placement area 2 or away from the power module placement area 2, thereby realizing the fixing or loosening operation of the power component it carries.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
