Description

Technical Field

[0001] This utility model relates to the field of IGBT substrate manufacturing technology, and specifically to a tooling for IGBT substrates. Background Technology

[0002] IGBT substrate (Insulated Gate Bipolar Transistor substrate) refers to the basic material and structural platform used to manufacture IGBT devices. It serves as the support and electrical connection core for IC chips or modules, providing mechanical support, electrical insulation, and a heat dissipation path.

[0003] In the production and processing of existing IGBT substrates, personnel often need to fix them on a fixture to facilitate the processing equipment to process their end faces. However, the existing tilting fixtures cannot provide good support and fixation for the IGBT substrates, which can easily cause shaking when personnel process the IGBT substrates. Therefore, they still have certain shortcomings.

[0004] In conclusion, it is necessary to invent a tooling for IGBT substrates. Utility Model Content

[0005] To address this issue, this utility model provides a tooling for IGBT substrates, which solves the problem that existing tilting tooling cannot effectively support and fix the IGBT substrates, causing them to shake during processing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tooling for an IGBT substrate, comprising a floor, with triangular support seats fixed on both sides of the top of the outer wall of the floor, a placement plate installed on the top of the outer wall of the triangular support seats, a placement component for placing the IGBT substrate provided on the top of the outer wall of the placement plate, and fixing components provided on the top of the outer wall of the placement plate and on the front and rear sides of the placement component.

The bottom of the outer wall of the substrate fixing placement seat is fixed to the center of the top of the outer wall of the placement plate. The shape and size of the substrate fixing placement seat are adapted to the shape and size of the IGBT substrate.

[0009] Preferably, the placement component is an adjustable substrate placement seat, which has a segmented structure. The bottom of the outer wall of the adjustable substrate placement seat is slidably connected to a sliding seat, and the top of the outer wall of the adjustable substrate placement seat is fixed to the outer wall of the sliding seat by a clamping bolt.

[0010] Preferably, each of the two adjustable substrate placement seats has a screw hole at one end, and the inner wall of each screw hole is threaded with a bidirectional screw. The outer wall of each bidirectional screw and the position near both ends of the adjustable substrate placement seat are threaded with a locking nut.

[0011] Preferably, the top of the outer wall of the placement plate and the position corresponding to the sliding seat are provided with sliding grooves, and the outer wall of the sliding seat is slidably connected to the inner wall of the corresponding sliding groove.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example 1:

[0023] See attached document Figures 1-3 This utility model provides a tooling for an IGBT substrate, including a base plate 100. Triangular support seats 110 are fixed to both sides of the top edge of the outer wall of the base plate 100. The triangular support seats 110 can be fixed to the base plate 100 and a placement plate 200 by bolts. The triangular support seats 110 can provide tilt support for the placement plate 200. The placement plate 200 is mounted on the top edge of the outer wall of the triangular support seats 110. A placement component for placing the IGBT substrate is provided on the top edge of the outer wall of the placement plate 200. The placement component is a substrate fixing placement seat 400, which is a fixed structure. The bottom of the outer wall of the substrate fixing seat 400 is fixed to the center of the top of the outer wall of the placement plate 200. The shape and size of the substrate fixing seat 400 are adapted to the shape and size of the IGBT substrate. The shape of the substrate fixing seat 400 is adapted to the shape of the IGBT substrate to be processed. Therefore, the IGBT substrate can be placed on the substrate fixing seat 400 during processing. At the same time, the substrate fixing seat 400 also has screw holes at the positions where screw holes are opened with the IGBT substrate, so that the personnel can fix the IGBT substrate to the top edge of the outer wall of the substrate fixing seat 400 with bolts.

[0024] Fixing components are provided on the top of the outer wall of the placement plate 200 and on both the front and rear sides of the placement component. The fixing components include side baffles 300. The two side baffles 300 are fixed to the front and rear sides of the top of the outer wall of the floor 100, respectively. The side baffles 300 can limit the upper and lower positions of the outer wall of the IGBT substrate from the upper and lower ends to ensure the fixing effect of the IGBT substrate. At the center of opposite sides of the top of the outer wall of the side baffles 300, an upper fixing block 310 and a lower fixing block 320 are respectively provided to press the IGBT substrate. The upper fixing block 310 and the lower fixing block 320 are threaded with fixing bolts. The upper fixing block 310 and the lower fixing block 320 can be fixed to the top of the outer wall of the side baffles 300 by bolts.

[0025] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description. That is, the personnel can take out the IGBT substrate to be fixed and place it on the top of the outer wall of the substrate fixing seat 400. After completion, the personnel can take out the screws to fix the IGBT substrate to the corresponding position of the top of the outer wall of the substrate fixing seat 400 for the first time. Then, the personnel can take out the upper fixing top block 310 and the lower fixing top block 320 and fix the upper fixing top block 310 and the lower fixing top block 320 to the top of the side baffle 300 with bolts, so that the upper fixing top block 310 and the lower fixing top block 320 tighten and limit the upper and lower sides of the IGBT substrate to ensure that the IGBT substrate will not shake during the processing.

[0026] Example 2:

[0027] See attached document Figures 4-5Compared to Embodiment 1, the difference in this embodiment is that the placement component is an adjustable substrate placement seat 500. The adjustable substrate placement seat 500 has a segmented structure, and each of the bottom ends of the outer wall of the adjustable substrate placement seat 500 is slidably connected to a sliding seat 520. The sliding seats 520 are mainly used to support the adjustable substrate placement seat 500 without hindering its movement. The top end of the outer wall of the adjustable substrate placement seat 500 is fixed to the outer wall of the sliding seat 520 by a clamping bolt 540. The clamping bolt 540 is used to secure the adjustable substrate placement seat 500 to the outer wall of the sliding seat 520 from the top end after adjustment. To prevent the adjustable substrate placement seats 500 from shaking during the fixing process, each of the two adjustable substrate placement seats 500 has a screw hole at one end. The inner wall of each screw hole is threaded with a bidirectional screw 510. Locking nuts are threaded onto the outer wall of the bidirectional screw 510 near both ends of the adjustable substrate placement seats 500. Personnel can control the simultaneous relative or opposite movement of the two adjustable substrate placement seats 500 by rotating the bidirectional screw 510. This allows for adjustment of the distance between the adjustable substrate placement seats 500, ensuring that the seats are positioned to fit the shape of the IGBT substrate to be fixed. The position is adjusted to accommodate IGBT substrates of various sizes within a certain range. The top of the outer wall of the placement plate 200 and the corresponding position of the sliding seat 520 are each provided with a groove. The outer wall of the sliding seat 520 is slidably connected to the inner wall of the corresponding groove. The top of the outer wall of the adjustable substrate placement seat 500 also has a strip-shaped clearance groove at the position corresponding to the clamping bolt 540. This prevents the clamping bolt 540 from affecting the movement of the adjustable substrate placement seat 500. A threaded rod 530 is rotatably connected to the inner wall side of each groove to control the movement of the sliding seat 520. Corresponding to the outer walls of the sliding seat 520 and the groove... Each threaded rod 530 has a screw hole at a corresponding position. The outer wall of the threaded rod 530 is threaded to the inner wall of the screw hole. The operator can rotate the threaded rod 530 in both directions, so that the sliding seat 520 can move along the slide groove through the screw hole. This allows the lateral distance between the two adjustable substrate placement seats 500 to be adjusted. In this design, the upper fixed top block 310 and the lower fixed top block 320 also need to be equipped with adjusting bolts 330 at the upper and lower positions near the side baffle 300. This allows the upper fixed top block 310 and the lower fixed top block 320 to better tighten and fix the upper and lower sides of the outer wall of the IGBT substrate.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
