Description

Technical Field

[0001] This utility model relates to the field of pressing equipment technology, specifically a quick-change elastic pressing mechanism for module substrates. Background Technology

[0002] IGBT (Insulated Gate Bipolar Transistor) modules, as core components in the field of power electronics, are widely used in new energy vehicles, rail transportation, smart grids, and industrial frequency converters. With increasing demands for high power density and high reliability, the packaging structure and heat dissipation technology of IGBT modules have become key factors limiting their performance. The substrate, as the core heat dissipation carrier of the IGBT module, directly affects the maintainability, heat dissipation effect, and operational stability of the processing equipment due to its efficient fixing, processing, and tooling replacement.

[0003] The existing technology still has the following drawbacks in its use:

[0004] The copper substrates used in the production of IGBT power modules and SiC power modules are designed as downward-curved arches, and the arches of the copper substrates produced in batches are inconsistent, ranging from about 0.3-0.5mm (a few have larger arches), which brings difficulties to the positioning and clamping during the production process.

[0005] In view of this, we propose a quick-change elastic clamping mechanism for module substrates to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to provide a quick-change elastic clamping mechanism for a module substrate to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-change elastic pressing mechanism for a module substrate, comprising a mechanism chassis, a sliding rail on the mechanism chassis, a left elastic quick-change pressing head and a right elastic quick-change pressing head respectively mounted on the sliding rail, a module positioning fixture between the left and right elastic quick-change pressing heads, a module plate mounted on the module positioning fixture, detection sensors at both the front and rear ends of the module plate, elastic pressing head lifting mechanisms at both the front and rear ends of the left and right elastic quick-change pressing heads, a lifting drive mechanism at the lower end of each elastic pressing head lifting mechanism, and a connection control mechanism between the front and rear ends of the left and right elastic quick-change pressing heads, the connection control mechanism including a horizontal drive mechanism.

[0008] Preferably, both the left and right elastic quick-change pressure heads include a pressure head and a base, with a rotating shaft on the base and a pressure rod mounted on the base via the rotating shaft.

[0009] Preferably, a pressure head is installed at the front end of the pressure rod, a compression spring is provided at the rear end of the pressure rod, and a baffle is provided above the rear end of the pressure rod.

[0010] Preferably, the sliding track is symmetrically arranged based on the mechanism chassis.

[0011] Preferably, the elastic pressure head lifting mechanism is controlled to lift by a lifting drive mechanism, and the connecting control mechanism is controlled to move horizontally by a horizontal drive mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a motion control and clamping mechanism to ensure motion stability and prevent interference with clamping, resulting in more stable overall clamping control. To ensure uniform clamping at all pressure points on the copper substrate, an elastic pressure head structure is designed, which automatically adjusts the pressure head height according to changes in pressure point height, ensuring production process stability and improving product yield. It also offers excellent applicability to different specifications and models of substrates from various customers, increasing the equipment's versatility. Attached Figure Description

[0018] Example 1

[0019] like Figure 1 and Figure 2As shown, this utility model proposes a quick-change elastic clamping mechanism for a modular substrate, including a mechanism chassis 1. A sliding rail 2 is provided on the mechanism chassis 1, and a left elastic quick-change pressure head 7 and a right elastic quick-change pressure head 5 are respectively mounted on the sliding rail 2. The sliding rail 2 supports the movement of the left and right elastic quick-change pressure heads 7 and 5, allowing them to separate and move closer together. A module positioning fixture 3 is provided between the left and right elastic quick-change pressure heads 7 and 5, and a module plate 4 is mounted on the module positioning fixture 3. The module positioning fixture 3 is used to install and place the module plate 4. Detection sensors 6 are provided at both the front and rear ends of the module plate 4. The detection sensors 6 are used to detect the placement of the module plate 4 and then transmit signals. The main control panel controls the subsequent steps. Both the left and right elastic quick-change pressure heads 7 and 5 are equipped with elastic pressure head lifting mechanisms 8 at their front and rear ends. The elastic pressure head lifting mechanisms 8 are controlled by lifting drive mechanisms 9, which can drive the entire left or right elastic quick-change pressure head 7 or 5 to move up and down. The lower end of the elastic pressure head lifting mechanism 8 is equipped with a lifting drive mechanism 9. A connection control mechanism 11 is provided between the front and rear ends of the left and right elastic quick-change pressure heads 7 and 5. The connection control mechanism 11 is equipped with a horizontal drive mechanism 10, which can control the movement of the connection control mechanism 11, so that the left and right elastic quick-change pressure heads 7 and 5 move on the sliding track 2.

[0020] Furthermore, both the left elastic quick-change pressure head 7 and the right elastic quick-change pressure head 5 include a pressure head 13 and a base 15. A rotating shaft 14 is provided on the base 15, and a pressure rod 16 is installed on the base 15 through the rotating shaft 14. When the pressure rod 16 is downward as a whole, the pressure head 13 presses against the module, and then the pressure rod 16 rotates and the rear end is downward.

[0021] Furthermore, a pressure head 13 is installed at the front end of the pressure rod 16, a compression spring 17 is provided at the rear end of the pressure rod 16, and a baffle 12 is provided above the rear end of the pressure rod 16. The compression spring 17 is used to facilitate the reset of the pressure rod 16 and to provide a certain pressure to the pressure rod 16. The baffle 12 is used to prevent the rear end of the pressure rod 16 from being raised too high when the compression spring 17 is reset.

[0022] Furthermore, the sliding track 2 is symmetrically arranged based on the mechanism chassis 1, and the sliding track 2 allows for better movement of the left elastic quick-change pressure head 7 and the right elastic quick-change pressure head 5.

[0023] Furthermore, the elastic pressure head lifting mechanism 8 is controlled to lift by the lifting drive mechanism 9, and the connecting control mechanism 11 is controlled to move horizontally by the horizontal drive mechanism 10. The lifting drive mechanism 9 controls the elastic pressure head lifting mechanism 8 to control the movement of the pressure rod 16 and clamp the product. The horizontal drive mechanism 10 controls the movement of the connecting control mechanism 11 to bring the left elastic quick-change pressure head 7 and the right elastic quick-change pressure head 5 closer to the module plate 4.

[0024] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
