[0052] Reference Figure 8-Figure 10 The heat shrink structure is arranged in the U-shaped frame 41, and the heat shrink structure is a heating wire arranged on the inner wall on both sides of the U-shaped frame 41, which is used to make the capacitor sleeve 17 set on the outer wall of the capacitor uniformly adhere to the outer wall of the capacitor. The heat shrink structure includes three resistance wire heating plates 42, and the three resistance wire heating plates 42 are respectively fixed on the top inner wall, the bottom inner wall and the inner wall on one side of the U-shaped frame 41. The function of the resistance wire heating plate 42 is to heat the capacitor sleeve 17 on the outer wall of the capacitor. The resistance wire heating plate 42 is electrically connected to the external power supply, and an L-shaped frame 38 is welded on the top of the base 1. A second motor 39 is fixed on the top of the L-shaped frame 38 through a frame. A rotating shaft 40 is rotated inside the L-shaped frame 38, and the top of this rotating shaft 40 is fixedly connected to the U-shaped frame 41. The output shaft of the second motor 39 is fixedly connected to the top of the rotating shaft 40 through a coupling. When the resistance wire heating plates 42 are started, they will heat the capacitor sleeve 17 on the outer wall of the capacitor. At the same time, the second motor 39 drives the U-shaped frame 41 to rotate. Such a design allows the outer wall of the capacitor sleeve 17 to be evenly heated, so that the capacitor sleeve 17 shrinks due to heat and fits on the outer wall of the capacitor to complete the packaging operation. This operation method is simple, does not require manual operation, has a high degree of automation, and can greatly improve the packaging efficiency.

[0053] Reference Figure 2 , Figure 3 and Fig. 9 The fixed structure is arranged at the top of the base 1, and is used to adsorb the capacitor on the placement convex plate 6 when the heat shrink structure is running. The fixed structure includes an arc-shaped guide plate 43 fixed on the top of the base 1, and the arc-shaped guide plate 43 is located below the L-shaped frame 38. At the top of multiple placement convex plates 6, adsorption grooves 8 are provided. These adsorption grooves 8 are used to adsorb capacitors to ensure that the capacitors will not shake during the packaging process. At the same time, the ends of multiple first vacuum cylinders 9 close to each other are fixedly connected with an L-shaped tube 14, and these L-shaped tubes 14 are fixedly connected with the corresponding adsorption grooves 8. In the first vacuum cylinder 9, a first piston plate 10 is sealed and slidably connected. A pull rod 11 is fixed on the side away from each other of these first piston plates 10. The end of the pull rod 11 away from the first piston plate 10 slides and extends to one side of the first vacuum cylinder 9, and a handle 13 is fixed. These handles 13 cooperate with the arc-shaped guide plate 43 to drive the first piston plate 10 to move outward. A first spring 12 is sleeved on the outer wall of the pull rod 11. One end of the first spring 12 is fixedly connected to a side of the first piston plate 10 away from the L-shaped tube 14 , and the other end is fixedly connected to an inner wall of one side of the first vacuum cylinder 9 .

[0054] Such a design enables the turntable 4 to drive the capacitor to move into the U-shaped frame 41, and when the turntable 4 rotates, the arc-shaped guide plate 43 will cooperate with the handle 13 to push the handle 13 to move outward. The movement of the handle 13 will drive the first piston plate 10 to pull outward, so that the adsorption groove 8 is in a negative pressure state, and the capacitor can be adsorbed on the top of the placement convex plate 6. In this way, the capacitor can be prevented from shaking when the capacitor sleeve 17 is heated and packaged later.

[0055] Reference Figure 3 Finally, a plurality of clearance holes 7 are provided in the placement boss 6. The function of these clearance holes 7 is to make way for the pins of the capacitor, thereby ensuring that the capacitor can be stably placed on the placement boss 6 without being disturbed by the pins.

[0056] Reference Fig. 9 and Fig.10 , the height of the capacitor sleeve 17 is set to be less than the distance between the top inner wall and the bottom inner wall of the U-shaped frame 41. This design enables the three resistance wire heating sheets 42 on the U-shaped frame 41 to effectively heat the capacitor sleeve 17 when the U-shaped frame 41 rotates, so that the capacitor sleeve 17 can be tightly and evenly attached to the top side wall and the bottom of the capacitor. This heating and attachment method ensures the close combination between the capacitor sleeve 17 and the capacitor, and improves the overall performance and stability of the capacitor.

[0057] Reference Figure 4 Next, we focus on the retaining frame 16 on the conveyor belt 15. The retaining frame 16 is fixed to the top of the conveyor belt 15 by bolts, and its main function is to limit the capacitor sleeve 17. When the capacitor sleeve 17 is transported to the specified position, the retaining frame 16 can ensure that the capacitor sleeve 17 is aligned with the placement tube 23 below. This design helps to improve the accuracy and efficiency of capacitor winding and packaging.

[0058] Example 2: Reference Fig.11 and Fig.12 , improved on the basis of Example 1: fixed seats 47 are fixed on both sides of the top of the retaining frame 16, and second tension springs 46 are fixed on the fixed seats 47. The other end of the second tension spring 46 is connected to the guide block 45, and the guide block 45 can slide on the top of the retaining frame 16. At the same time, a vertical rod 48 is fixed on the top of the guide block 45. On both sides of the mounting plate 21, we fixed two trapezoidal plates 44, which cooperate with the vertical rod 48 to drive the guide block 45 to move toward the middle.

[0059] When mounting plate 21 moves down to absorb capacitor sleeve 17, and is sleeved on capacitor outer wall, the trapezoidal plate 44 on mounting plate 21 both sides can contact with vertical rod 48, and promotes vertical rod 48 and guide block 45 to move to the middle.At this moment, second tension spring 46 is in tension state.Two guide blocks 45 can guide capacitor sleeve 17 to the middle position during movement.This design ensures that when placing tube 23 moves down to be sleeved on the outer wall of capacitor sleeve 17, placing tube 23 and capacitor sleeve 17 can accurately align, avoids the generation of misalignment phenomenon.

[0060] A method for using a high-precision power capacitor rolling and packaging integrated machine comprises the following steps:

[0061] S1, the capacitor is rolled by the capacitor winding machine 2, and the rolled capacitor is placed in the capacitor welding machine 3 under the grasping of the mechanical arm (existing equipment), and the welding of the pins is completed. Then the mechanical arm places the welded capacitor on the adjacent placement convex plate 6, and the pins just pass through the clearance hole 7;

[0062] S2. The motor drives the turntable 4 to rotate, and the turntable 4 transports the capacitor to the bottom of the mounting plate 21, and the conveyor belt 15 transports the capacitor sleeve 17 to be packaged to the bottom of the corresponding placement tube 23. The output shaft of the electric push rod 22 drives the mounting plate 21 and the placement tube 23 to move downward. When the placement tube 23 covers the top of the capacitor sleeve 17, the bottom end of the U-shaped rod 27 drives the second piston plate 26 to move upward and squeeze the second spring 28 under the action of the fixed stopper 29. At this time, the second piston plate 26 moves upward to generate negative pressure between the top inner wall of the placement tube 23 and the top of the capacitor sleeve 17, so that the capacitor sleeve 17 can be adsorbed into the placement tube 23. In the process of the mounting plate 21 moving downward, the pin hole 30 is aligned with the pin shaft 32, and the pin shaft 32 is inserted into the pin hole 30 under the pulling force of the first tension spring 33, which is used to brake the U-shaped rod 27, so that the placement tube 23 can be continuously The capacitor sleeve 17 is adsorbed, and then the mounting plate 21 is moved up and reset. Then the first motor 20 drives the rotating column 19 and the mounting plate 21 to reverse the direction. The capacitor sleeve 17 is located directly above the capacitor. The electric push rod 22 drives the mounting plate 21 to move down again until the capacitor sleeve 17 is sleeved on the capacitor. At this time, another placement tube 23 can adsorb the capacitor sleeve 17 again, and the pin shaft 32 on the corresponding U-shaped rod 27 just extends into the give way groove 36, and the cooperation of the baffle plate 34 and the guide inclined surface 37 drives the pin shaft 32 to move outward. The first tension spring 33 is in a stretched state, and the pin shaft 32 is disengaged from the pin hole 30, releasing the braking of the U-shaped rod 27, so that the U-shaped rod 27 can be reset under the elastic force of the second spring 28 in the later stage. At this time, the adsorption of the capacitor sleeve 17 by the placement tube 23 is released, so that the mounting plate 21 and the placement tube 23 can be moved up and reset in the later stage.

[0063] S3. After the capacitor sleeve 17 is installed on the capacitor, the turntable 4 drives the capacitor to move into the U-shaped frame 41, and when the turntable 4 rotates, the arc-shaped guide plate 43 cooperates with the handle 13 to push the handle 13 to move outward, and the handle 13 pulls the first piston plate 10 outward. The adsorption groove 8 is in a negative pressure state, and the capacitor can be adsorbed on the top of the placement convex plate 6 to avoid the capacitor from shaking when the capacitor sleeve 17 is heated and packaged later. Then the resistance wire heating plate 42 starts to heat the capacitor sleeve 17 on the outer wall of the capacitor, and the second motor 39 drives the U-shaped frame 41 to rotate, which can evenly heat the outer wall of the capacitor sleeve 17, so that the capacitor sleeve 17 shrinks and fits on the outer wall of the capacitor due to heat, and the packaging operation is completed. The operation is simple, no manual operation is required, the degree of automation is high, and the packaging efficiency is greatly improved;

[0064] S4. In addition, when the mounting plate 21 moves down to adsorb the capacitor sleeve 17 and sleeves the capacitor sleeve 17 on the outer wall of the capacitor, the mounting plate 21 pushes the corresponding vertical rod 48 and the guide block 45 to move toward the middle through the trapezoidal plates 44 on both sides. The second tension spring 46 is in a stretched state at this time, and the two guide blocks 45 can guide the capacitor sleeve 17 to the middle position, so that the placement tube 23 can be sleeved on the outer wall of the capacitor sleeve 17 when the mounting plate 21 moves down later, avoiding misalignment between the placement tube 23 and the capacitor sleeve 17.

[0065] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 22, the first motor 20, the resistance wire heating plate 42 and the second motor 39 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
