[0055] The present invention proposes an IGBT side frame module heating and riveting integrated equipment, which integrates two functions of heating and rivet ring 415 riveting. It can automatically heat the IGBT side frame module 414 and rivet the rivet ring 415 without manual riveting, reducing manual participation and greatly improving the speed, efficiency and accuracy of heating and riveting. The riveting quality is high, the riveting quality is stable, and the error rate is low. In addition, the IGBT side frame module heating and riveting integrated equipment of the present invention adopts multiple points 413 for heating and riveting in sequence, which significantly improves the heating and riveting efficiency of the IGBT side frame module 414, reduces the floor space, and improves the utilization rate of the factory. At the same time, the loading device 2, the transplanting and conveying device 3, the heating and riveting device 4, and the cooling and conveying device 5 are independently installed without interfering with or affecting each other, and are easy to maintain in the later stage. The overall maintenance cost of the heating and riveting integrated equipment is low, and it has strong economic adaptability.

[0056] Specifically, in one embodiment of the invention, as shown in FIG1 , the IGBT side frame module heating and riveting integrated equipment includes a machine 1 and a loading device 2, a transplanting and conveying device 3, a heating and riveting device 4, and a cooling and conveying device 5 provided on the machine 1. The loading device 2 is used to deliver the tray 412 containing the IGBT side frame module 414 to the transplanting and conveying device 3. The transplanting and conveying device 3 is used to deliver the tray 412 containing the IGBT side frame module 414 to the heating and riveting device 4 for heating and riveting. The heating and riveting device 4 heats and rivets the IGBT side frame modules in the tray 412. The frame module 414 is heated and riveted. After the heating and riveting are completed, the heating and riveting device 4 sends the tray 412 containing the IGBT side frame module 414 that has been heated and riveted back to the transplanting and conveying device 3. The transplanting and conveying device 3 sends the tray 412 containing the IGBT side frame module 414 that has been heated and riveted to the cooling and conveying device 5 to cool the IGBT side frame module 414 in the tray 412. After cooling is completed, the tray 412 containing the IGBT side frame module 414 can be removed to complete the heating and riveting operation of the IGBT side frame module 414.

[0057] As can be seen from Figure 1, in the IGBT side frame module heating and riveting integrated equipment of this embodiment, the loading device 2, the transplanting and conveying device 3, the heating and riveting device 4, and the cooling and conveying device 5 are installed independently without interfering with or affecting each other. This design makes it easy to maintain each device in the later stage, and the overall maintenance cost of the heating and riveting integrated equipment is low, and it has strong economic adaptability.

[0058] The feeding device 2 , the transplanting and conveying device 3 , the heating and riveting device 4 , and the cooling and conveying device 5 in the IGBT side frame module heating and riveting integrated equipment of this embodiment are described in detail one by one below.

[0059] In this embodiment, as shown in Figure 3, the transplanting and conveying device 3 includes a guide rail 39, a conveyor line body 31, and a transmission belt 37. The guide rail 39 is fixedly connected to the machine 1. There is a pair of guide rails 39, which are arranged at intervals and parallel to each other; the conveyor line body 31 is slidably installed on the guide rail 39, and the conveyor line body 31 is provided with a motor 33 and a pair of conveyor belts 32 arranged at intervals and parallel to each other. The motor 33 is fixedly connected to the conveyor line body 31 and is transmission-connected to the conveyor belt 32 to drive the conveyor belt 32 to rotate the conveyor pallet 412. The conveying direction of the conveyor belt 32 is perpendicular to the length direction of the guide rail 39. This design makes it convenient to send the pallet 412 into the cooling conveying device 5 and each heating riveting device 4.

[0060] 3 , the conveying direction of the conveyor belt 2 32 and the direction of movement of the conveyor line body 2 31 along the guide rail 39 are shown by the arrows in FIG3 . The conveyor line body 2 31 is provided with an in-position sensor 310 and a lifting device 34 at the unloading end of the conveyor belt 2 32. The lifting device 34 is vertically fixed on the machine platform 1 . A stopper 35 is installed on the upper end of the lifting device 34 . The stopper 35 rises under the drive of the lifting device 34 to block the pallet 412 on the conveyor belt 2 32 from unloading, thereby protecting the pallet 412 and preventing the pallet 412 from sliding off the conveyor belt 2 32 under the action of inertia after the conveyor belt 2 32 stops rotating. When the pallet 412 is transferred to the unloading end by the conveyor belt 2 32 , it can be detected by the in-position sensor 310 . With this design, the lifting device 34 can be controlled according to this detection signal to drive the stopper 35 to rise.

[0061] In this embodiment, as shown in Figure 3, the conveyor line body 2 31 is provided with an in-position sensor 315 at the loading and unloading ends of the conveyor belt 2 32. The in-position sensor 315 is used to detect whether a pallet 412 enters or leaves the conveyor line body 2 31. Specifically, when the loading device 2 feeds the pallet 412 into the conveyor belt 2 32, the in-position sensor 315 located at the loading end of the conveyor belt 2 32 can detect that the pallet 412 enters the conveyor belt 2 32, and accordingly, the conveyor belt 2 32 can be controlled to start to replace the loading device 2 to continue to transport the pallet 412; when the pallet 412 completely leaves the conveyor belt 2 32 and enters the cooling conveying device 5, the in-position sensor 315 located at the unloading end of the conveyor belt 2 32 can detect that the pallet 412 completely leaves the conveyor belt 2 32, and accordingly, the conveyor belt 2 32 can be controlled to stop moving.

[0062] In this embodiment, as shown in Figure 3, one end of the guide rail 39 in the length direction is provided with a motor three 36 fixedly connected to the machine 1, and the other end of the guide rail 39 in the length direction is provided with a wheel seat 311 fixedly connected to the machine 1, and the output shafts of the wheel seat 311 and the motor three 36 are rotatably mounted with pulley one 312, and the transmission belt 37 is tightly sleeved on the two pulleys 312, and the transmission belt 37 is driven to rotate by the motor three 36. The moving direction of the transmission belt 37 is parallel to the guide rail 39, and the transmission belt 37 passes through the conveyor line body 2 31. The conveyor line body 2 31 is fixedly provided with a connecting block 38, and the connecting block 38 presses the conveyor belt on the conveyor line body 2 31, and the conveyor line body 2 31 is driven by the transmission belt 37 to slide along the length direction of the guide rail 39 to send the tray 412 into each heating riveting device 4.

[0063] In this embodiment, as shown in Figure 3, a limit block 313 and an in-position sensor 2 314 are provided on the machine 1 next to the wheel seat 311. The conveyor line body 2 31 slides along the guide rail 39 to the end close to the wheel seat 311 and can contact the limit block 313 and be detected by the in-position sensor 2 314. With this design, the limit block 313 can prevent the conveyor line body 2 31 from sliding off the guide rail 39, thereby protecting the safety of the conveyor line body 2 31. When the in-position sensor 2 314 detects the conveyor line body 2 31, the transmission belt 37 can be controlled to stop rotating to prevent the transmission belt 37 from driving the conveyor line body 2 31 to slide off the guide rail 39. Once the in-position sensor 2 314 fails, the limit block 313 can prevent the conveyor line body 2 31 from sliding off the guide rail 39. The double protection design ensures the safety of the conveyor line body 2 31 and prevents it from slipping off the guide rail 39.

[0064] In this embodiment, as shown in Figure 1, the loading device 2 and the cooling conveying device 5 are respectively arranged on both sides of a pair of guide rails 39, and the loading device 2 can be connected with the loading end of the second conveyor belt 32, so that the loading device 2 can feed the tray 412 into the second conveyor line body 31, and the cooling conveying device 5 can be connected with the unloading end of the second conveyor belt 32, so that the tray 412 leaves the second conveyor line body 31 and enters the cooling conveying device 5; there are multiple heating riveting devices 4, and they are evenly distributed on both sides of a pair of guide rails 39, and the heating riveting devices 4 can be connected with the second conveyor belt 32, so that the tray 412 moves between the second conveyor belt 32 and the heating riveting devices 4, that is, the tray 412 on the second conveyor belt 32 can enter the heating riveting device 4, and the tray 412 on the heating riveting device 4 can return to the second conveyor belt 32. The design of multiple heating riveting devices 4 can make the IGBT side frame module heating riveting integrated equipment of this embodiment have higher heating riveting efficiency. The IGBT side frame modules 414 on multiple trays 412 can be heated and riveted simultaneously at the same time, thereby improving the utilization rate of the machine 1, reducing the floor space occupied by the IGBT side frame module heating and riveting integrated equipment, and improving the utilization rate of the factory.

[0065] In this embodiment, as shown in Figure 2, the loading device 2 includes: a conveyor line body 21 and a motor 23. The conveyor line body 21 is fixedly installed on the machine platform 1, and a pair of conveyor belts 22 that are spaced apart and parallel to each other are rotatably installed on the conveyor line body 21; the motor 23 is fixedly connected to the conveyor line body 21 and is in transmission connection with the conveyor belt 22, and is used to drive the conveyor belt 22 to rotate and deliver the tray 412 on the conveyor belt 22 to the conveyor belt 2 32.

[0066] In this embodiment, as shown in Figure 6, the cooling conveying device 5 includes: a conveying line body 4 51, a motor 4 53, a top plate 2 54, a fan 58 and an in-position sensor 56. The conveying line body 4 51 is fixedly installed on the machine 1. A pair of conveying belts 4 52 arranged at intervals and parallel to each other are rotatably installed on the conveying line body 4 51. The conveying belt 2 32 can transfer the tray 412 thereon to the conveying belt 4 52. The motor 4 53 is fixedly connected to the conveying line body 4 51 and is in transmission connection with the conveying belt 4 52. The conveying belt 4 52 is driven by the motor 4 53 to rotate the conveying tray 412. The top plate 2 54 is located between the pair of conveying belts 4 52. A lifting device 2 55 is connected to the bottom of the second 54, and the lifting device 2 55 is vertically fixed on the machine 1. When the tray 412 is transferred to the top of the top plate 2 54 by the conveyor belt 4 52, the lifting device 2 55 can push the top plate 2 54 to lift the tray 412 and separate it from the conveyor belt 4 52, so that the fan 58 can blow air to the tray 412 to cool down the IGBT side frame module 414 on the tray 412. After the IGBT side frame module 414 on the tray 412 has finished cooling down, the lifting device 2 55 is controlled to drive the tray 412 to descend and reset, and then the conveyor belt 4 52 is controlled to continue rotating to send the tray 412 away from the IGBT side frame module heating and riveting integration equipment of this embodiment.

[0067] In this embodiment, as shown in Figure 6, the fan 58 is provided above the conveyor line body four 51 and is fixedly connected to the machine 1 through the mounting bracket 57. The fan 58 is used to blow air onto the tray 412 after being lifted by the top plate two 54, so as to cool the IGBT side frame module 414 on the tray 412; the in-position sensor five 56 is provided on the conveyor line body four 51, and is used to detect whether the tray 412 has reached directly above the top plate two 54, so as to timely control the action of the lifting device two 55.

[0068] The working principle of the IGBT side frame module heating and riveting integrated equipment of this embodiment is that the tray 412 containing the IGBT side frame module 414 is sent to the conveyor belt 2 32 by the conveyor belt 1 22 of the loading device 2, and then the transmission belt 37 drives the conveyor belt 2 32 to move along the guide rail 39 to align with the conveyor belt 3 49 of each heating and riveting device 4, and then the conveyor belt 2 32 sends the tray 412 to the conveyor belt 3 49, and the heating and riveting device 4 heats and rivets the IGBT side frame module 414 on the tray 412 on the conveyor belt 3 49. After the heating and riveting are completed, the conveyor belt 3 49 sends the tray 412 back to the conveyor belt 2 32, and then the conveyor belt 2 32 sends the tray 412 to the conveyor belt 4 52, and the cooling conveying device 5 cools the IGBT side frame module 414. After the cooling is completed, the conveyor belt 4 52 sends the tray 412 away from the IGBT side frame module heating and riveting integrated equipment of this embodiment.

[0069] The structure of the heating riveting device 4 is described in detail below.

[0070] In this embodiment, as shown in Figures 4 and 5, the heating riveting device 4 includes: a hood, a heating plate 422 and a lifting device 47. The cross-section of the hood is inverted U-shaped. The hood includes a pair of vertically parallel side panels 44 and a top plate 45 horizontally fixedly installed on the upper ends of the two side panels 44.

The lower end of the column 42 is fixedly connected to the bottom plate 41. The bottom plate 41 is fixedly installed on the machine 1. This design, on the one hand, is convenient for installing and fixing the lifting device 47. The lifting device 47 is vertically fixed on the bottom plate 41. On the other hand, the ventilation and heat dissipation inside the hood are good, thereby preventing the high temperature of the heating plate 422 from affecting the safety of the hood and the lifting device 47.

The upper end of the second column 420 is fixedly connected to the third mounting plate 421. The third mounting plate 421 is a heat insulation plate, and a heating plate 422 is fixedly installed on it. The IGBT side frame module 414 is heated by the heating plate 422. The design of the heat insulation plate can prevent the heating plate 422 from transferring a large amount of heat downward to affect the safety of the lifting device 47.

[0072] In this embodiment, as shown in Figures 4 and 5, a pair of pulleys 48 are rotatably mounted on the two opposite inner side walls of the hood, and a pair of pulleys 48 are tightly sleeved on a conveyor belt 3 49. The two conveyor belts 3 49 are symmetrically arranged. A motor 5 427 is fixedly mounted on the hood, and the motor 5 427 is transmission-connected to the pulley 2 48 to drive the conveyor belt 3 49 to rotate. The conveyor belt 2 32 can transfer the tray 412 thereon to the conveyor belt 3 49, and the lower surface of the tray 412 on the conveyor belt 3 49 is in contact with the upper surface of the heating plate 422. Contact, thereby heating the tray 412 through the heating plate 422, and then heating the IGBT side frame module 414 in the tray 412, so as to achieve simultaneous heating of the rivet rings 415 of multiple IGBT side frame modules 414 on one tray 412, which significantly improves the heating efficiency of the IGBT side frame module 414. A thermocouple 423 and a heating rod 424 are provided on the heating plate 422. The heating rod 424 is used to heat the heating plate 422, and the thermocouple 423 is used to detect the temperature of the heating plate 422 to ensure heating accuracy.

[0073] In this embodiment, the lifting device 47 can lift the tray 412 through the heating plate 422, so that the buffer pressure head can press rivet the rivet ring 415 of the IGBT side frame module 414 on the tray 412. A plurality of acupoints 413 are provided on the tray 412, such as the three acupoints 413 shown in Figure 5, and each acupoint 413 is used to place an IGBT side frame module 414. With this design, multiple IGBT side frame modules 414 can be placed on a tray 412. As shown in Figures 4 and 5, multiple buffer pressure heads are vertically installed on the inner top surface of the hood, and the multiple buffer pressure heads correspond one-to-one to the rivet rings 415 of the multiple IGBT side frame modules 414. With this design, the rivet rings 415 of multiple IGBT side frame modules 414 on a tray 412 can be press-riveted at the same time, which significantly improves the press-riveting efficiency of the IGBT side frame modules 414.

[0074] It can be seen that the IGBT side frame module heating and riveting integrated equipment of this embodiment integrates the two functions of heating and riveting ring 415 riveting, and can automatically heat the IGBT side frame module 414 and rivet the rivet ring 415 without manual riveting, thereby reducing manual participation and greatly improving the speed, efficiency and accuracy of heating and riveting. The riveting quality is high, the riveting quality is stable, and the error rate is low.

[0075] In this embodiment, after the conveyor belt 2 32 transfers the tray 412 thereon to the conveyor belt 3 49, the conveyor belt 3 49 first drives the tray 412 to move to the heating position to be heated by the heating plate 422. After the heating is completed, the lifting device 47 lifts the tray 412 through the heating plate 422, so that the buffer pressure head rivets the rivet ring 415 of the IGBT side frame module 414 on the tray 412, thereby realizing automatic heating of the IGBT side frame module 414 and riveting of the rivet ring 415. After the riveting is completed, the tray 412 descends and resets, and then the conveyor belt 3 49 sends the tray 412 back to the conveyor belt 2 32, and the conveyor belt 2 32 sends the tray 412 into the cooling conveyor device 5.

[0076] Furthermore, in this embodiment, as shown in Figure 5, a plurality of positioning blocks 416 are evenly distributed next to each acupoint 413 on the tray 412, and the plurality of positioning blocks 416 correspond one-to-one to the rivet ring 415 of the IGBT side frame module 414 in the acupoint 413. This design facilitates the plurality of positioning blocks 416 to simultaneously position the buffer pressure head corresponding to the IGBT side frame module 414 to ensure the quality of riveting. Accordingly, a positioning hole 419 is provided on the positioning block 416, and the lower end of the buffer pressure head can be inserted into the positioning hole 419 for positioning. After positioning, the buffer pressure head rivets the rivet ring 415 of the IGBT side frame module 414 on the tray 412, thereby ensuring high quality of riveting, good quality, low error rate and high accuracy of riveting.

[0077] Specifically, after the conveyor belt 2 32 transfers the tray 412 thereon to the conveyor belt 3 49, the conveyor belt 3 49 first drives the tray 412 to move to the heating position to be heated by the heating plate 422. After heating, the lifting device 47 passes through the heating plate 422 to lift the tray 412 so that the positioning hole 419 positions the buffer pressure head. In this process, as shown in Figures 4 and 5, an in-place sensor 425 is vertically fixedly installed on the top plate 1 45. The in-place sensor 425 is used to detect the height difference between itself and the tray 412, that is, the lifting position of the tray 412. If the lower end of the buffer pressure head deviates and cannot be inserted into the positioning hole 419, the lifting height of the tray 412 does not meet the standard. Based on this, the heating riveting device 4 can be controlled to be shut down for maintenance. On the contrary, if the lower end of the buffer pressure head can be smoothly inserted into the positioning hole 419, the lifting height of the tray 412 meets the standard. The riveting operation can continue, that is, after the positioning hole 419 positions the buffer pressure head, the tray 412 descends and contacts the conveyor belt three 49, and the conveyor belt three 49 drives the tray 412 to continue moving until the rivet ring 415 on the tray 412 is located directly under the buffer pressure head, and then the lifting device 47 lifts the tray 412 again, and cooperates with the buffer pressure head to rivet the rivet ring 415 of the IGBT side frame module 414 on the tray 412. After the riveting is completed, the tray 412 descends and resets, and then the conveyor belt three 49 sends the tray 412 back to the conveyor belt two 32, and the conveyor belt two 32 sends the tray 412 to the cooling conveyor device 5. Before the buffer pressure head rivets the rivet ring 415 of the IGBT side frame module 414 on the tray 412, the positioning block 416 is first used to position the buffer pressure head to ensure the position accuracy of the buffer pressure head, ensure high riveting quality, stable riveting quality, and low error rate.

[0078] In this embodiment, as shown in Figure 5, the buffer pressure head includes: a pressure rod 417 and a spring 418. The pressure rod 417 is vertically arranged, and its upper end is fixedly connected to the top plate 45. The lower end of the pressure rod 417 can be inserted into the positioning hole 419 for positioning and inserted into the rivet ring 415 for riveting. The spring 418 is sleeved on the lower end of the pressure rod 417. When the lower end of the pressure rod 417 is inserted into the rivet ring 415 for riveting, the spring 418 is compressed by the rivet ring 415. With this design, the spring 418 can be used to compress and fix the rivet ring 415, thereby preventing the rivet ring 415 from shaking during the riveting process of the pressure rod 417, affecting the riveting accuracy and quality.

[0079] In this embodiment, as shown in Figures 4 and 5, support strips 411 fixedly connected to the side plates 44 are provided on both sides of the heating plate 422. The support strips 411 are arranged horizontally and do not contact the heating plate 422. The tray 412 presses down the conveyor belt three 49 and moves along the upper surface of the support strips 411. This design is conducive to the support strips 411 supporting the tray 412, so that the tray 412 is driven by the conveyor belt three 49 to move smoothly horizontally, avoiding the tray 412 pressing down the conveyor belt three 49 to cause the conveyor belt three 49 to deform, causing the tray 412 to tilt or shake and shift, affecting heating and riveting.

[0080] In this embodiment, as shown in Figures 4 and 5, the limiting strips 426 are fixedly installed on the side vertical plates 44. The limiting strips 426 on the two side vertical plates 44 limit the pallet 412 so that it can only move horizontally along the conveying direction of the conveyor belt three 49 under the drive of the conveyor belt three 49 without shaking, thereby ensuring the position accuracy of the pallet 412 and facilitating subsequent heating and riveting operations.

[0081] In this embodiment, as shown in Figures 4 and 5, a stopper 2 410 is provided at one end of the limiting strip 426, which blocks the pallet 412 from being further driven by the conveyor belt 3 49 through the limiting strip 426, thereby preventing the pallet 412 from falling from one end of the conveyor belt 3 49, thereby protecting the safety of the pallet 412.
