Description

Technical Field

[0001] This utility model mainly relates to the field of IGBT bending technology, specifically an IGBT bending fixture. Background Technology

[0002] IGBT transistors have three pins that require bending, and the three pins are of different lengths; the middle pin is relatively longer, while the pins on the sides are relatively weaker.

[0003] Existing bending fixtures typically require manual lifting of the pressing mechanism after bending one IGBT before replacing it with the next. This necessitates continuous manual replacement of IGBTs during batch bending, resulting in a large workload and low processing efficiency. Utility Model Content

[0004] This utility model provides a solution that addresses the problem of overly simplistic existing technical solutions. It offers a significantly different solution by providing an IGBT bending fixture. This solves the problem mentioned in the background that existing bending fixtures require processing one IGBT bend before lifting the pressing mechanism to replace the next IGBT, resulting in a large amount of manual labor and low processing efficiency.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An IGBT bending fixture includes a base and a support platform. The support platform is mounted on the base, and a transport turntable is mounted on the support platform. A transport box for placing IGBTs is mounted on the transport turntable. A pressure block for bending the IGBTs is mounted on the support platform, and a top plate for positioning the transport box is mounted on the support platform. A transmission assembly is mounted between the pressure block and the top plate.

[0007] Preferably, a motor is provided on the base, and a rotating shaft is provided at the output end of the motor. The rotating shaft is rotatably connected inside the base, and the end of the rotating shaft away from the motor is connected to a transport turntable.

[0008] Preferably, the transport boxes are arranged in a circular array on the transport turntable, and the transport boxes are provided with placement slots and pin slots, with the placement slots and pin slots being connected.

[0009] Preferably, a cylinder is provided on the support platform, and a pressure block is provided at one end of the cylinder telescopic rod.

[0010] Preferably, a support housing is provided on the support platform, and a telescopic sleeve is provided inside the support housing. One end of the telescopic sleeve is connected to the top plate, and a spring is sleeved on the telescopic sleeve.

[0011] Preferably, the transmission assembly includes a transmission block and a flat gear. The transmission block is disposed on the pressure block, and the flat gear is disposed on the support housing. A first tooth groove is formed on the top plate, and a second tooth groove is formed on the transmission block. The flat gear meshes with the first tooth groove and the second tooth groove respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by arranging multiple transport boxes in a circular array on the transport turntable, the transport boxes transport IGBTs to the front of the pressure block, where they can be bent. In this way, IGBTs on the transport boxes not in front of the pressure block can be replaced. This allows for the replacement of unprocessed IGBTs while they are being bent, thus improving processing efficiency.

[0013] A top plate is installed on the processing table. The top plate is supported on the transport turntable by a spring. The elasticity of the spring ensures that the top plate will not affect the rotation of the transport turntable. At the same time, when the transport box rotates to fit against the top plate, the transport box is directly in front of the pressure block. At this time, the transport turntable stops rotating. The IGBTs inside the transport box can be bent by the pressure block. The position of the transport box is determined by the top plate, eliminating the need for manual judgment of the position of the transport box. This not only enables precise processing but also reduces the workload of manual labor.

[0014] When the pressure block moves forward to bend the IGBTs in the transport box, the pressure block will drive the top plate to move backward through the transmission component. At this time, the pressure block completes the bending of the IGBTs. As the pressure block moves backward, the transport box is no longer obstructed by the top plate, and the transport turntable will rotate again to move the transport box away. While the pressure block moves backward, it drives the top plate to move forward again through the transmission component and press against the transport turntable. The top plate will then position the next transport box. This achieves automation and reduces manual workload.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] Please refer to the appendix carefully. Figures 1-5 An IGBT bending fixture includes a base 1 and a support platform 2. The support platform 2 is mounted on the base 1. A transport turntable 3 is mounted on the support platform 2. A transport box 6 for placing IGBTs is mounted on the transport turntable 3. A pressure block 10 for bending the IGBTs is mounted on the support platform 2. A top plate 13 for positioning the transport box 6 is mounted on the support platform 2. A transmission assembly is provided between the pressure block 10 and the top plate 13.

[0027] The specific operating procedure of this utility is as follows: The IGBT is placed inside the transport box 6, and then the transport box 6 is rotated by the transport turntable 3. When one side of the transport box 6 is in contact with the top plate 13, the transport box 6 is in front of the pressure block 10. The pressure block 10 is used to bend the IGBT. At the same time, when the pressure block 10 moves forward, the pressure block 10 drives the top plate 13 to move backward through the transmission component. At this time, the restriction of the top plate 13 on the transport box 6 is released. After the IGBT bending is completed, the pressure block 10 is moved backward. At the same time, the transport turntable 3 continues to drive the transport box 6 to rotate. After the pressure block 10 moves backward and resets, the top plate 13 moves forward and resets, pressing against the transport turntable 3. The top plate 13 continues to position the next transport box 6.

[0028] Please refer to Figure 3 A motor 4 is installed on the base 1, and a rotating shaft 5 is installed at the output end of the motor 4. The rotating shaft 5 is rotatably connected inside the base 1, and the end of the rotating shaft 5 away from the motor 4 is connected to the transport turntable 3.

[0029] Start motor 4, which drives rotating shaft 5 to rotate, rotating shaft 5 drives transport turntable 3 to rotate, and transport turntable 3 drives transport box 6 to rotate to transport IGBTs.

[0030] Please refer to Figures 1-3 The transport boxes 6 are arranged in a circular array on the transport turntable 3. The transport boxes 6 are provided with placement slots 7 and pin slots 8, and the placement slots 7 and pin slots 8 are connected.

[0031] Insert the IGBT head into the placement slot 7 and fix it in place. Insert the three pins of the IGBT into the three pin slots 8 respectively. The pin slots 8 are used to guide the bending of the three pins of the IGBT.

[0032] Please refer to Figure 4 and Figure 5 A cylinder 9 is installed on the support platform 2, and a pressure block 10 is installed at one end of the telescopic rod of the cylinder 9.

[0033] Start cylinder 9, cylinder 9 drives telescopic rod to extend and retract, telescopic rod pushes pressure block 10 forward, pressure block 10 moves forward and fits against transport box 6 to perform corner processing on IGBT.

[0034] Please refer to Figure 4 and Figure 5 A support housing 11 is provided on the support platform 2. A telescopic sleeve 14 is provided inside the support housing 11. One end of the telescopic sleeve 14 is connected to the top plate 13. A spring 15 is sleeved on the telescopic sleeve 14.

[0035] When the pressure block 10 is in the rear, the pressure block 10 does not restrict the top plate 13 through the transmission assembly. At this time, the top plate 13 is pushed forward and pressed against the transport turntable 3 under the action of the spring 15. Due to the elasticity of the spring 15, the top plate 13 will not affect the rotation of the transport turntable 3. The telescopic sleeve 14 is used to support and restrict the spring 15.

[0036] Please refer to Figure 4 and Figure 5 The transmission assembly includes a transmission block 12 and a flat gear 16. The transmission block 12 is mounted on the pressure block 10, and the flat gear 16 is mounted on the support housing 11. A first tooth groove 17 is provided on the top plate 13, and a second tooth groove 18 is provided on the transmission block 12. The flat gear 16 meshes with the first tooth groove 17 and the second tooth groove 18 respectively.

[0037] When the pressure block 10 moves forward, the pressure block 10 drives the transmission block 12 to move forward. When the transmission block 12 moves forward a certain distance, the second tooth groove 18 meshes with the spur gear 16. The second tooth groove 18 drives the spur gear 16 to move. The spur gear 16 drives the top plate 13 to move backward through the first tooth groove 17. The top plate 13 separates from the transport turntable 3. The spur gear 16 is rotatably connected to the inside of the limiting housing through the rotating rod.
