Description

Technical Field

[0001] This application relates to the field of IGBT module technology, and in particular to a flip-blowing mechanism suitable for IGBT modules. Background Technology

[0002] IGBT modules (Insulated Gate Bipolar Transistor modules) are composite fully controllable voltage-driven power semiconductor devices that combine the low on-state voltage drop of bipolar transistors (BJTs) with the high input impedance of metal-oxide-semiconductor field-effect transistors, making them suitable for high-voltage, high-current applications.

[0003] The existing IGBT module's flip-blowing mechanism has blind spots when blowing on a flat surface. After blowing, debris will remain on the product. Furthermore, it is not easy to use a vacuum cleaner to remove the debris during blowing, and the debris may be blown to the outside and contaminate the equipment.

[0004] Therefore, we propose a flip-blowing mechanism suitable for IGBT modules.

[0005] Application content

[0006] In view of the shortcomings of the existing production technology, the applicant provides a flip-blowing mechanism suitable for IGBT modules.

[0007] The technical solution adopted in this application is as follows:

[0008] A flip-blowing mechanism for IGBT modules, comprising:

[0009] The protective cover has openings at both the top and bottom.

[0010] The rotating mechanism includes a rotating platform, which is located inside the protective cover. A connecting frame is fixed to the rotating platform, and the other end of the connecting frame is rotatably connected to the inner wall of the protective cover.

[0011] The clamping mechanism, mounted on the connecting frame, is used to fix the product.

[0012] A robotic arm for picking and placing materials is mounted above a protective cover and is used to transport products.

[0013] The purge nozzle is located below the protective cover;

[0014] The flip-top cover mechanism includes a support frame, a connecting shaft, a cover plate, and a cylinder. The output end of the cylinder is rotatably connected to the cover plate, and the other end of the cylinder is rotatably connected to the support frame. The support frame is fixed to the outside of the protective cover. The connecting shaft is rotatably connected to the top of the support frame and is fixedly connected to the cover plate.

[0015] The cover plate is rotated along the connecting shaft by a cylinder, and the cover plate can close the top of the protective cover.

[0016] Its further features are:

[0017] The rotating mechanism also includes a motor, which is located outside the protective cover, and the motor's drive shaft is connected to the rotating platform.

[0018] The clamping mechanism includes an electric gripper, which includes replaceable gripping fingers.

[0019] The purging nozzle is connected to the air source.

[0020] An installation block is provided on the outside of the protective cover, and the support frame is fixed on the installation block.

[0021] The cylinder extends, and the output end of the cylinder pushes up the end of the cover plate that is rotatably connected to the cylinder, causing the cover plate to rotate along the connecting shaft until the top of the cover plate closes the protective cover, and the cover plate is in a closed state.

[0022] The cylinder retracts, and the output end of the cylinder drives the end of the cover plate that is rotatably connected to the cylinder to move downward. The cover plate rotates along the connecting shaft, and the other end of the cover plate moves away from the protective cover, thus opening the cover plate.

[0023] The beneficial effects of this application are as follows:

[0024] This application features a compact and reasonable structure, and is easy to operate. With the cover open, a robotic arm places a product to be blown onto the clamping mechanism, which then clamps the product. A cylinder extends, its output lifting the end of the cover that is rotatably connected to it, causing the cover to rotate along the connecting shaft until it closes the top of the protective cover. A motor drives a rotating platform, which in turn rotates a connecting frame. The connecting frame, through the clamping mechanism, causes the product to rotate, and the blowing nozzles blow the product. As the product rotates, blowing occurs at different angles along the x-axis, effectively removing debris from all directions. The blown debris is then removed by an industrial vacuum cleaner. After blowing, the cylinder retracts, and its output moves the end of the cover rotatably connected to it downwards, causing the cover to rotate along the connecting shaft. The other end of the cover moves away from the protective cover, opening the cover. The robotic arm then removes the blown product, completing one process. The rotating mechanism ensures 360° blowing along the product's x-axis, reducing blind spots in planar blowing. It also offers high adjustability in terms of rotation speed, direction, and dwell time.

[0025] In addition, this application also has the following advantages:

[0026] (1) The flip cover mechanism improves the working efficiency of the vacuum cleaner when blowing away debris and prevents debris from contaminating the equipment and causing malfunctions.

[0027] (2) The clamping mechanism can be replaced with different clamping fingers to accommodate a variety of products. Attached Figure Description

[0037] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0038] like Figures 1-5 As shown, a flip-blowing and purging mechanism suitable for IGBT modules includes a protective cover 1, a rotating mechanism 2, a clamping mechanism 3, a material handling robot 4, a flip-cover mechanism 5, and a purging nozzle 6.

[0039] The protective cover 1 has openings at both the top and bottom.

[0040] A rotating mechanism 2 is mounted on the protective cover 1. The rotating mechanism 2 includes a rotating platform 201, a motor 202, and a connecting frame 203. The rotating platform 201 is located inside the protective cover 1, and the motor 202 is located outside the protective cover 1. The drive shaft of the motor 202 is connected to the rotating platform 201, and the rotating platform 201 is rotated through the drive shaft of the motor 202. The connecting frame 203 is located inside the protective cover 1. One end of the connecting frame 203 is fixedly connected to the rotating platform 201, and the other end of the connecting frame 203 is rotatably connected to the inner wall of the protective cover 1.

[0041] The clamping mechanism 3 is fixed on the connecting frame 203. The clamping mechanism 3 includes an electric gripper 301, which includes replaceable gripper fingers 302. The gripper fingers 302 can be replaced to adapt to different products.

[0042] The pick-and-place robot 4 is positioned above the protective cover 1 and is used to transport products. The pick-and-place robot 4 transports the products to the clamping mechanism 3, where the clamping mechanism 3 clamps the products. After the products are purged, the pick-and-place robot 4 removes the products from the clamping mechanism 3, and then places another product to be purged onto the clamping mechanism 3, where the clamping mechanism 3 clamps the product for further purging.

[0043] The flip-top cover mechanism 5 is located on the outside of the protective cover 1. The flip-top cover mechanism 5 includes a support frame 501, a connecting shaft 502, a cover plate 503, and a cylinder 504. The support frame 501 is fixed to the outside of the protective cover 1. The top of the support frame 501 is provided with a rotatable connecting shaft 502. The output end of the cylinder 504 is rotatably connected to the cover plate 503, and the other end of the cylinder 504 is rotatably connected to the bottom of the support frame 501. One end of the connecting shaft 502 is fixedly connected to the cover plate 503.

[0044] In one embodiment, a mounting block is provided on the outside of the protective cover 1, and the support frame 501 is fixed on the mounting block.

[0045] The cover plate 503 has two states: open and closed.

[0046] When cover 503 is in the open state and needs to be closed, cylinder 504 extends, and the output end of cylinder 504 pushes upward to the end of cover 503 that is rotatably connected to cylinder 504, causing cover 503 to rotate along connecting shaft 502 until cover 503 closes the top of protective cover 1, at which point cover 503 is in the closed state. Then the product undergoes a purging operation.

[0047] When cover plate 503 is in the closed state, and it is necessary to open cover plate 503, cylinder 504 retracts. The output end of cylinder 504 drives the end of cover plate 503 that is rotatably connected to cylinder 504 to move downward. Cover plate 503 rotates along connecting shaft 502, and the other end of cover plate 503 moves away from protective cover 1, thus opening cover plate 503. This allows a product to be picked up or placed by the material handling robot 4 after the purging operation is completed.

[0048] The purge nozzle 6 is located below the protective cover 1.

[0049] The purge nozzle 6 is positioned below the clamping mechanism 3, facilitating the purge of the nozzle 6.

[0050] In one embodiment, the purge nozzle 6 is connected to an air source.

[0051] Specifically, the gas source can be a pressure tank.

[0052] In practical use, with the cover plate 503 in the open state, the loading and unloading robot 4 places a product to be blown onto the clamping mechanism 3, which then clamps the product. The cylinder 504 extends, and its output end lifts the end of the cover plate 503 that is rotatably connected to the cylinder 504, causing the cover plate 503 to rotate along the connecting shaft 502 until it closes the top of the protective cover 1, at which point the cover plate 503 is in the closed state. The motor 202 drives the rotating platform 201 to rotate, which in turn drives the connecting frame 203 to rotate. The connecting frame 203, through the clamping mechanism 3, causes the product to rotate, and the blowing nozzle 6 blows the product. As the product rotates, it completes blowing at different angles along the x-axis, effectively removing debris from all directions. The blown debris is then sucked away by an industrial vacuum cleaner. After the purging is completed, the cylinder 504 retracts. The output end of the cylinder 504 drives the end of the cover plate 503 that is rotatably connected to the cylinder 504 to move downward. The cover plate 503 rotates along the connecting shaft 502. The other end of the cover plate 503 moves away from the protective cover 1, opens the cover plate 503, and the material handling robot 4 takes away the purged product, completing one process.

[0053] The rotating mechanism 2 ensures 360° blowing along the product's x-axis, reducing blind spots in planar blowing. It offers high adjustability in rotation speed, direction, and dwell time. The clamping mechanism 3 allows for the replacement of different clamping fingers 302 to accommodate various products. The flip-top cover mechanism 5 improves the vacuum cleaner's efficiency when blowing away debris and prevents debris from contaminating the equipment and causing malfunctions.

[0054] The above description is an explanation of this application and not a limitation thereof. The scope of this application is defined by the claims. Within the scope of protection of this application, any form of modification may be made.
