Two rectangular holes 30 are formed in the inner wall of the chute 29. Two lead screws 31 are fixedly connected to the activity plate 28. The lead screws 31 penetrate through the corresponding rectangular holes 30. A nut 32 is sleeved outside the lead screws 31, and the nut 32 is in contact with the outer wall of the push plate 27. A rotating shaft 33 is rotatably connected to the encapsulation table 1. The encapsulation table 1 is fixedly installed with a second servo motor 34. The output end of the second servo motor 34 is fixedly connected to the rotating shaft 33. The top end of the rotating shaft 33 is fixedly connected with a second connecting plate 35. The second connecting plate 35 is fixedly installed with a pushing frame 36. And the pushing frame 36 is of a U-shaped structure. Two supporting plates 37 are disposed below the pushing frame 36. A connecting shaft 38 is fixedly connected to the bottom of the supporting plate 37, and the connecting shaft 38 is rotatably connected to the pushing frame 36. The pushing frame 36 is provided with an angle adjuster adapted to the connecting shaft 38. The base 8 is fixedly installed with a bracket 43. The top end of the bracket 43 is fixedly connected with a receiving hopper 42 adapted to the supporting plate 37. And the supporting plate 37 is located above the receiving hopper 42.

The output ends of the third hydraulic expansion rods 40 are fixedly connected with toothed plates 41, and the two toothed plates 41 are respectively engaged with the two second gears 39; When the box body of the packaged IGBT module moves to the ejection station, the ejection hole 4 on the accommodation shell 2 moves above the ejection rod 22. The second compression spring 25 is in a compressed state in the initial state. The second compression spring 25 exerts a downward pressure on the movable seat 21, so that the bottom of the movable seat 21 is in close contact with the top of the second stop plate 24. When the lifting seat 3 moves downward, the lifting seat 3 comes into contact with the top of the movable plate 28. As the lifting seat 3 continues to move downward, the lifting seat 3 drives the movable plate 28 and the push plate 27 to move downward synchronously. The bottom end of the push plate 27 presses the support plate 44, so that the support plate 44 tilts relative to the packaging table 1. One end of the support plate 44 away from the push plate 27 pushes the movable seat 21 to move upward relative to the fixed column 23 and the packaging table 1. The movable seat 21 drives the ejection rod 22 to move upward relative to the packaging table 1. The ejection rod 22 ejects the box body of the packaged IGBT module out of the accommodation shell 2 through the corresponding ejection hole 4. At this time, the second servo motor 34 drives the rotating shaft 33 and the second connecting plate 35 to rotate. The second connecting plate 35 drives the pushing frame 36 to rotate from the collection station to the ejection station. The support plate 37 moves below the box body of the IGBT module, and the ejection rod 22 is located between the two support plates 37. As the rotating shaft 33 and the second connecting plate 35 continue to rotate, the pushing frame 36 pushes the box body of the packaged IGBT module out of the top of the ejection rod 22. The two support plates 37 support the bottom of the box body of the packaged IGBT module. When the box body of the packaged IGBT module moves to the collection station, the third hydraulic telescopic rod 40 drives the toothed plate 41 to move. The toothed plate 41 drives the connecting shaft 38 and the support plate 37 to rotate through the second gear 39, changing the inclination angle of the support plate 37. The box body of the packaged IGBT module slides onto the receiving hopper 42 from the support plate 37 due to its own gravity. When the lifting seat 3 moves upward, the lifting seat 3 no longer presses the movable plate 28. The second compression spring 25 drives the movable seat 21 and the ejection rod 22 to move downward to the initial height, and the movable seat 21 pushes the support plate 44 to rotate in the reverse direction, so that the support plate 44 pushes the push plate 27 and the movable plate 28 to move upward to the initial height. When it is necessary to adjust the initial distance between the movable plate 28 and the lifting seat 3, the staff drives the nut 32 to rotate, so that the nut 32 is no longer in close contact with the push plate 27. The staff drives the movable plate 28 to move vertically relative to the push plate 27. The movable plate 28 drives the screw rod 31 to slide relative to the rectangular hole 30. After the position of the movable plate 28 is adjusted, the staff drives the nut 32 to rotate. The nut 32 is in close contact with the outer wall of the push plate 27. The nut 32 and the movable plate 28 are fixed relative to the push plate 27, completing the adjustment of the initial distance between the movable plate 28 and the lifting seat 3, ensuring that when the lifting seat 3 descends to the preset position, the lifting seat 3 can drive the support plate 44 to rotate to the preset angle through the movable plate 28 and the push plate 27.

[0023] A packaging process for an IGBT component in this embodiment uses the IGBT component packaging equipment as described above and includes the following steps: Step 1: The staff places the bottom end of the IGBT module box to be encapsulated into the receiving shell 2; Step 2: The driving member drives the rotating sleeve 5 to rotate. The rotating sleeve 5 drives the receiving shell 2 to rotate synchronously through the first connecting plate 6, so that the IGBT module box to be encapsulated moves to the encapsulation station; Step 3: The lifting member drives the lifting seat 3 to move downward. The lifting seat 3 presses and encapsulates the IGBT module box through the pressing structure; Step 4: After the encapsulation is completed, the driving member drives the rotating sleeve 5 to rotate, so that the encapsulated IGBT module box moves to the ejection station, and the IGBT module box is ejected from the receiving shell 2 through the ejection assembly.

[0024] Working principle: The staff places the bottom end of the IGBT module box to be encapsulated into the receiving shell 2. The driving member drives the rotating sleeve 5 to rotate. The rotating sleeve 5 drives the receiving shell 2 to rotate synchronously through the first connecting plate 6, so that the IGBT module box to be encapsulated moves to the encapsulation station. The lifting member drives the lifting seat 3 to move downward. The lifting seat 3 presses and encapsulates the IGBT module box through the pressing structure. After the encapsulation is completed, the driving member drives the rotating sleeve 5 to rotate, so that the encapsulated IGBT module box moves to the ejection station, and the IGBT module box is ejected from the receiving shell 2 through the ejection assembly. During the process of ejecting the encapsulated IGBT module box, the IGBT module box located at the encapsulation station can still be encapsulated, reducing the time interval between two encapsulations and improving the work efficiency; The initial state of the first compression spring 11 is in a compressed state. The first compression spring 11 exerts a pressure on the pressing plate 9, and the bottom of the first stop disk 13 is in close contact with the top of the pressing shell 7. The first hydraulic telescopic rod 14 drives the movable ring 10 to move downward relative to the pressing shell 7, changing the initial length between the movable ring 10 and the pressing plate 9, thereby adjusting the initial length of the first compression spring 11. The second hydraulic telescopic rod 16 drives the lifting seat 3 to move downward, and the lifting seat 3 can drive the pressing shell 7 and the pressing plate 9 to move downward synchronously. When the pressing shell 7 moves downward to a preset position, the bottom of the pressing plate 9 is in close contact with the top of the IGBT module box, and at this time, the pressing plate 9 moves upward relative to the pressing shell 7 to a preset position. The first compression spring 11 exerts a downward force on the pressing plate 9, and the bottom of the first stop disk 13 is no longer in contact with the top of the pressing shell 7, and the pressing plate 9 can press and encapsulate the top of the IGBT module box. The first servo motor 19 drives the first gear 20 to rotate, and the first gear 20 can drive the rotating sleeve 5 to rotate through the toothed ring 17; When the box body of the packaged IGBT module moves to the ejection station, the ejection hole 4 on the accommodation shell 2 moves above the ejection rod 22. The second compression spring 25 is in a compressed state in the initial state. The second compression spring 25 exerts a downward pressure on the movable seat 21, so that the bottom of the movable seat 21 is in close contact with the top of the second stop plate 24. When the lifting seat 3 moves downward, the lifting seat 3 comes into contact with the top of the movable plate 28. As the lifting seat 3 continues to move downward, the lifting seat 3 drives the movable plate 28 and the push plate 27 to move downward synchronously. The bottom end of the push plate 27 presses the support plate 44, so that the support plate 44 tilts relative to the packaging table 1. One end of the support plate 44 away from the push plate 27 pushes the movable seat 21 to move upward relative to the fixed column 23 and the packaging table 1. The movable seat 21 drives the ejection rod 22 to move upward relative to the packaging table 1. The ejection rod 22 ejects the box body of the packaged IGBT module out of the accommodation shell 2 through the corresponding ejection hole 4. At this time, the second servo motor 34 drives the rotating shaft 33 and the second connecting plate 35 to rotate. The second connecting plate 35 drives the pushing frame 36 to rotate from the collection station to the ejection station. The support plate 37 moves below the box body of the IGBT module, and the ejection rod 22 is located between the two support plates 37. As the rotating shaft 33 and the second connecting plate 35 continue to rotate, the pushing frame 36 pushes the box body of the packaged IGBT module out of the top of the ejection rod 22. The two support plates 37 support the bottom of the box body of the packaged IGBT module. When the box body of the packaged IGBT module moves to the collection station, the third hydraulic telescopic rod 40 drives the toothed plate 41 to move. The toothed plate 41 drives the connecting shaft 38 and the support plate 37 to rotate through the second gear 39, changing the tilt angle of the support plate 37. The box body of the packaged IGBT module slides from the support plate 37 to the receiving hopper 42 due to its own gravity. When the lifting seat 3 moves upward, the lifting seat 3 no longer presses the movable plate 28. The second compression spring 25 drives the movable seat 21 and the ejection rod 22 to move downward to the initial height, and the movable seat 21 pushes the support plate 44 to rotate in the reverse direction, so that the support plate 44 pushes the push plate 27 and the movable plate 28 to move upward to the initial height. When it is necessary to adjust the initial distance between the movable plate 28 and the lifting seat 3, the staff drives the nut 32 to rotate, so that the nut 32 is no longer in close contact with the push plate 27. The staff drives the movable plate 28 to move vertically relative to the push plate 27. The movable plate 28 drives the lead screw 31 to slide relative to the rectangular hole 30. When the position of the movable plate 28 is adjusted, the staff drives the nut 32 to rotate. The nut 32 and the outer wall of the push plate 27 are in close contact. The nut 32 and the movable plate 28 are fixed relative to the push plate 27, completing the adjustment of the initial distance between the movable plate 28 and the lifting seat 3, ensuring that when the lifting seat 3 descends to the preset position, the lifting seat 3 can drive the support plate 44 to rotate to the preset angle through the movable plate 28 and the push plate 27.
