[0002] An IGBT module is a modular semiconductor product consisting of an IGBT chip and a freewheeling diode chip (FWD) packaged together using a specific circuit bridge. This module features energy saving, easy installation and maintenance, and stable heat dissipation, and is widely used in equipment such as frequency converters and UPS uninterruptible power supplies. During the soldering and processing of IGBT modules, a carrier is typically required for auxiliary fixation.

[0003] Currently, among existing welding fixtures, such as the patent with authorization announcement number CN214558638U, this utility model relates to the field of integrated circuit manufacturing technology, and in particular to a welding fixture for a 4G alarm service module. The fixture frame is a rectangular ring, and four clamping devices are respectively arranged on the four sides of the fixture frame. A support device is arranged at the bottom of the interior of the fixture frame. The clamping device includes a support frame fixedly connected to the four outer sides of the fixture frame, and an elastically telescopic clamping rod is arranged on the support frame. The support device includes a base plate fixedly connected to the bottom of the fixture frame.

[0004] However, during the use of the equipment, it was found that after the equipment clamped and fixed the module, it was not convenient to move and adjust the welding angle and position of the module, which reduced the flexibility of the welding process. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-power IGBT module welding carrier that improves the positional stability of IGBT module welding, enhances the flexibility of tilt angle adjustment during welding at different positions of the IGBT module, and improves ease of use.

[0006] This utility model discloses a high-power IGBT module welding carrier, comprising a support platform and two sets of limiting members, the two sets of limiting members being respectively disposed on the left and right sides of the support platform; it also includes a clamping device, a driving device, a support device, a chassis, a first motor, and a C-shaped frame. The clamping device is provided on the support platform for fixing the module. The support platform is rotatably mounted on the top of the chassis. The first motor is mounted on the inner side wall of the chassis, and its output end is connected to the support platform. The chassis is rotatably mounted on the C-shaped frame via the driving device. The C-shaped frame is mounted on the support device, which drives the C-shaped frame to rotate and move for adjustment. The carrier is used for welding the module. The IGBT module is placed between two sets of limiting members at the top of the support platform. Then, the front and rear sides of the IGBT module are clamped and fixed by the clamping device to improve the positional stability of the IGBT module during welding. The drive device drives the chassis to rotate, causing the chassis to swing and tilt the support platform left and right. The support device drives the C-frame to rotate, causing the C-frame to swing and tilt the support platform back and forth through the chassis, improving the flexibility of tilt angle adjustment when welding the IGBT module in different positions.

[0011] Preferably, the clamping device includes two sets of second cylinders, which are mounted opposite each other on the top of the support platform; the IGBT module is clamped by the opposing movement of the moving ends of the two sets of second cylinders, thereby improving the positioning effect of the IGBT module welding process.

[0012] Preferably, it also includes multiple sets of bolts, which are respectively screwed onto the two sets of limiting members, and the top of the support platform is provided with multiple sets of threaded holes; by screwing multiple sets of bolts onto the threaded holes at different positions, the convenience of fixing and adjusting the position of the two sets of limiting members is improved.
