Description

Technical Field

[0001] The present invention relates to a mechanism for clamping an outer shell, and in particular to a cylindrical power battery steel shell sealing machine. Background Art

[0002] As we all know, cylindrical batteries (especially 4680 cylindrical batteries) are batteries with high capacity, long cycle life and wide operating temperature range. They are widely used in various occasions. For example, they can be used as power batteries for new energy vehicles, electric bicycles and electric motorcycles.

[0003] The production and processing of cylindrical batteries requires grooving the outer wall of the battery steel shell and sealing the grooved shell. Sealing the shell requires a sealing machine.

[0004] At present, for the sealing of 4680 cylindrical batteries, since its steel shell has a diameter of 48 mm and a height of 80 mm, the hardness of the steel shell of the 4860 cylindrical battery is much greater than that of the commonly used 18650 cylindrical battery. Therefore, for the sealing of the steel shell of the 4680 cylindrical battery, the existing sealing machine needs to use multiple sealing mechanisms to seal the steel shell conveyed by the horizontal turntable in sequence, so as to achieve the purpose of sealing the grooved steel shell.

[0005] However, since the existing sealing machine adopts multiple sealing mechanisms arranged in sequence and at equal intervals around the horizontal turntable along the rotation direction of the horizontal turntable, and considering the loading and unloading positions, the size of the horizontal turntable needs to be made larger to ensure that the sealing mechanism, the loading and unloading positions are aligned with the corresponding clamping mechanisms on the horizontal turntable every time the horizontal turntable steps forward; this will cause the size of the horizontal turntable to be too large, resulting in a large volume of the entire machine, and will also cause the sealing mechanism that seals last to be too close to the adjacent sealing mechanism.

[0006] Therefore, there is an urgent need for a cylindrical power battery steel shell sealing machine that can avoid the horizontal turntable being too large and too close to each other to overcome the above-mentioned defects. Summary of the Invention

[0034] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0035] See also Figure 1 and Figure 15a The cylindrical power battery steel shell sealing machine 100 of the present invention is suitable for sealing the grooved steel shell 200, so that the state of the steel shell 200 after treatment is shown. Figure 15d As shown, the state of the steel shell 200 after the groove is rolled is shown Figure 15a As shown, the cylindrical steel shell 200 has an annular groove 210 on its port side wall.

[0036] Combined with Figure 2 and Figure 5The cylindrical power battery steel shell sealing machine 100 of the present invention includes a frame 10, a horizontal turntable 20, five clamping mechanisms 30, a turntable driving mechanism 40, a first sealing mechanism 50a, a second sealing mechanism 50b, a third sealing mechanism 50c, a fourth sealing mechanism 50d, a middle turntable 60a, a mounting plate 60b, a support stand 60c and a transfer mechanism 70. The horizontal turntable 20 can be horizontally rotatably assembled on the frame 10, and the frame 10 provides a support function and an assembly place for the horizontal turntable 20. Preferably, the horizontal turntable 20 is located directly above the frame 10 to facilitate the installation operation of the first sealing mechanism 50a, the second sealing mechanism 50b, the third sealing mechanism 50c, the fourth sealing mechanism 50d, the mounting plate 60b and the support stand 60c on the frame 10; all the clamping mechanisms 30 are on the horizontal turntable 20 along the rotation direction of the horizontal turntable 20 (for example Figure 1 or Figure 3 The steel shell 200 is clamped by the clamping mechanism 30 and the steel shell 200 is clamped by the clamping mechanism 30. The horizontal turntable 20 rotates to drive the clamping mechanism 30 on the horizontal turntable 20 and the steel shell 200 clamped by the clamping mechanism 30 to rotate together, thereby meeting the need of the horizontal turntable 20 to transport the steel shell 200 forward; preferably, all the clamping mechanisms 30 are arranged in a circle with equal central angles on the horizontal turntable 20, that is, the central angle between any two adjacent clamping mechanisms 30 is the same, and the central angle is equal to 360 degrees divided by the clamping mechanism 30. Since the number of clamping mechanisms 30 described above is 5, correspondingly, the center angle between any two adjacent clamping mechanisms 30 is 62 degrees. Of course, according to actual needs, the clamping mechanisms 30 can also be selected as two, three, four or six. In addition, in order to realize that each clamping mechanism 30 is transported step by step, the center angle of each advancement of the horizontal turntable 20 is related to the number of the clamping mechanisms 30, and the center angle is obtained by dividing 360 degrees by the number of the clamping mechanisms 30.

[0037] At the same time, the turntable drive mechanism 40 is assembled on the frame 10, and the frame provides support and assembly space for the turntable drive mechanism 40. Preferably, the turntable drive mechanism 40 is located directly below the horizontal turntable 20 and is hidden by the frame 10, so that the arrangement of the turntable drive mechanism 40 on the frame 10 is simpler. Of course, according to actual needs, the arrangement of the turntable drive mechanism 40 on the frame 10 can also be other, so it is not limited to this; the turntable drive mechanism 40 is used to drive the horizontal turntable 20 to rotate to meet the power requirement of the horizontal turntable 20 for horizontal rotation; for example, the turntable drive mechanism 40 is composed of a motor, a reduction gearbox and an angle divider. Of course, according to actual needs, the turntable drive mechanism 40 can also be other mechanisms, so it is not limited to this.

[0038] Furthermore, the first to fourth sealing mechanisms 50d are used to complete the sealing process of the steel shell 200 clamped by the clamping mechanism 300 and conveyed by the horizontal turntable 20. For example, the state of the steel shell 200 after being sealed by the first sealing mechanism 50a is shown in FIG. Figure 15b As shown, the state of the steel shell 200 after being sealed by the second sealing mechanism 50b is shown in FIG. Figure 15c As shown, the state of the steel shell 200 obtained after passing through the third sealing mechanism 50c and the fourth sealing mechanism 50d is shown in FIG. Figure 15d As shown, four sealing steps are adopted to effectively avoid the defects of serious deformation, burr formation and flattening of the steel shell 200 due to the instantaneous large force; and the first to third sealing mechanisms 50c are sequentially spaced along the rotation direction of the horizontal turntable 20 and arranged around the horizontal turntable 20 to be assembled on the frame 10, and the first to third sealing mechanisms 50c are aligned with the steel shell 200 clamped by the clamping mechanism 30 and conveyed by the horizontal turntable 20 along the vertical direction of the frame 10. Preferably, the first sealing mechanism The central angle between 50a and the second sealing mechanism 50b is the same as the central angle between the second sealing mechanism 50b and the third sealing mechanism 50c. The central angle is a multiple of the angle obtained by dividing 360 degrees by the number of clamping mechanisms 30, and the optimal value is 1. This ensures that the first sealing mechanism 50a, the second sealing mechanism 50b and the third sealing mechanism 50c are each aligned with a clamping mechanism 30 on the horizontal turntable 20 each time the horizontal turntable 20 steps forward, thereby improving work efficiency.

[0039] Then, the middle turntable 60a is located in front of the third sealing mechanism 50c at a distance along the rotation direction of the horizontal turntable 20, one side of the middle turntable 60a is located directly above the horizontal turntable 20, and the other side opposite to the middle turntable 60a protrudes from the horizontal turntable 20 along the radial direction of the horizontal turntable 20, so that the middle turntable 60a partially overlaps with the horizontal turntable 20 along the up and down direction of the frame 10; the middle turntable 60a is horizontally rotatably assembled on the mounting plate 60b, and the mounting plate 60b provides a bearing function for the middle turntable 60a. The middle turntable 60a is also connected to the horizontal turntable 20 in a transmission manner to ensure that the two rotate synchronously; the middle turntable 60a is provided with three rotating parts along the rotation direction of the middle turntable 60a (see Figure 5 Preferably, all the clamping structures 61 are arranged in a circle with equal central angles on the middle turntable 60a, so that the central angle between any two adjacent clamping structures 61 is 120 degrees, that is, 360 degrees is divided by the number of clamping structures 61, to ensure that the middle turntable 60a follows the horizontal turntable 20 every time it steps, so that the clamping mechanism 30 and the fourth sealing mechanism 50d on the horizontal turntable 20 are each aligned with a clamping structure 61 up and down, thereby effectively improving work efficiency.

[0040] Finally, the fourth sealing mechanism 50d is assembled on the frame 10, and the frame 10 provides support and assembly space for the fourth sealing mechanism 50d. The fourth sealing mechanism 50d is also aligned with the position 62 where the middle turntable 60a protrudes from the horizontal turntable 20. During the rotation of the middle turntable 60a, any clamping structure 61 selectively rotates to a position aligned with the fourth sealing mechanism 50d in the vertical direction of the frame 10. The state is shown in FIG. Figure 1 As shown, or aligned with the clamping mechanism 30, the state is shown Figure 5 As shown, it is to ensure that the same clamping structure 61 can be rotated to a position aligned with the fourth sealing mechanism 50d, or aligned with the clamping mechanism 30 during the rotation of the middle turntable 60a, so as to meet the needs of the steel shell 200 clamped by the clamping mechanism 30 being transferred to the clamping structure 61, and the steel shell 200 at the clamping structure 61 being sealed by the fourth sealing mechanism 50d; the mounting plate 60b is located directly above the middle turntable 60a and protrudes radially from the middle turntable 60a along the horizontal turntable 20, so that the middle turntable 60a is suspended directly below the mounting plate 60b, avoiding the mounting plate 60b from interfering with the rotation of the middle turntable 60a; the supporting stand 60c is assembled on the frame 10, so that The support stand 60c is fixed to the frame 10 and is also assembled and connected to the position of the mounting plate 60b protruding from the center turntable 60a to prevent the support stand 60c from interfering with the rotation of the center turntable 60a and making the structure of the mounting plate 60b, the support stand 60c and the center turntable 60a more compact. The transfer mechanism 70 is assembled on the frame 10, and the frame 10 provides support and assembly space for the transfer mechanism 70. The transfer mechanism 70 is used to transfer the steel shell 200 on the clamping mechanism 30 to the clamping structure 61, ensuring the reliability of the transfer of the steel shell 200 on each clamping mechanism 30 transported by the horizontal turntable 20 to the clamping structure 61. More specifically, as follows:

[0041] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the cylindrical power battery steel shell sealing machine 100 of the present invention further includes a lower ejector drive 80a, a material unloading and delivery line 80b, a material loading and delivery line 80c and a material loading mechanism 80d. The lower top drive 80a and the unloading material delivery line 80b are both located in front of the fourth sealing mechanism 50d along the rotation direction of the middle turntable 60a, and the loading conveyor line 80c is located between the fourth sealing mechanism 50d and the first sealing mechanism 50a along the rotation direction of the horizontal turntable 20. Preferably, the loading conveyor line 80c is also located between the unloading material delivery line 80b and the first sealing mechanism 80a along the rotation direction of the horizontal turntable 20; the lower top drive 80a is assembled on the mounting plate 60b, and preferably, the lower top drive 80a is assembled on the mounting plate 60b from above the mounting plate 60b, and the mounting plate 60b provides support for the lower top drive 80a, and the output end 81 of the lower top drive 80a is arranged downward and is equipped with a lower top head 82, which is opposite to the steel shell 200 clamped by the clamped structure 61 transported by the middle turntable 60a. The lower ejector head 82 is driven by the lower ejector driver 80a to push the aligned steel shells 200 downwards. The unloading and delivery line 80b is located directly below the lower ejector head 82. The unloading and delivery line 80b is used to receive the steel shells 200 pushed down by the lower ejector head 82 and deliver the steel shells 200 outwards, so as to facilitate the automatic unloading and delivery of the steel shells 200. The loading conveyor line 80c is assembled on the frame 10 and is located beside the horizontal turntable 20. The loading mechanism 80d is assembled on the mounting plate 60b. Preferably, the loading mechanism 80d is assembled on the mounting plate 60b from above the mounting plate 60b. The loading mechanism 80d is located above both the loading conveyor line 80c and the horizontal turntable 20. The loading mechanism 80d is used to transfer the steel shells 200 delivered by the loading conveyor line 80c to the clamping mechanism 30 on the horizontal turntable 20 to achieve the purpose of automatic loading. Specifically, combined with Figure 14The material feeding line 80b includes a linear trough 83, a straight push block 84 and a straight push driver 85; the linear trough 83 is mounted on the frame 10 and extends horizontally, the first end of the linear channel 831 of the linear trough 83 is located directly below the lower head 82, the second end of the linear channel 831 of the linear trough 83 is away from the horizontal turntable 20, and the straight push block 84 is placed in the first end of the linear channel 831; the straight push driver 85 is mounted on the linear trough 83 and is located outside the linear channel 831, and the straight push driver 85 is also connected to the straight push block 84. The assembly connection is achieved by driving the direct-push ejector block 84, which pushes the steel shell 200, which has been pushed down by the lower ejector head 82 into the first end of the linear channel 831, toward the second end of the linear channel 831 under the drive of the direct-push actuator 85. This simplifies the structure of the unloading and feeding line 80b while achieving automatic unloading. For example, the direct-push actuator 85 and the lower ejector head 80a are each pneumatic cylinders, but hydraulic cylinders can be used as needed. In addition, the loading mechanism 80d is a vertical rotation mechanism, and the loading conveyor line 80c is a belt conveyor line, but this is not limited to this. It should be noted that, depending on actual needs, the loading conveyor line 80c and the loading mechanism 80d can be deleted, or the unloading and feeding line 80b, the lower ejector head 80a, and the lower ejector head 82 can be deleted, or the loading conveyor line 80c, the loading mechanism 80d, the unloading and feeding line 80b, the lower ejector head 80a, and the lower ejector head 82 can be deleted.

[0042] like Figure 2 and Figure 5 As shown, the optimal way to achieve the transmission connection between the horizontal turntable 20 and the middle turntable 60a is that a driving wheel 21 is coaxially fixed directly above the horizontal turntable 20, that is, the horizontal turntable 20 and the driving wheel 21 are fixed together with the same axis to ensure that the driving wheel 21 rotates synchronously with the horizontal turntable 20; a driven wheel 22 is coaxially fixed directly above the middle turntable 60a, that is, the middle turntable 60a and the driven wheel 22 are fixed together with the same axis to ensure that the driven wheel 22 rotates synchronously with the middle turntable 60a; the driving wheel 21 and the driven wheel 22 are horizontally aligned. Preferably, the driving wheel 21 and the driven wheel 22 are located directly above the mounting plate 60b, so as to avoid the driving wheel 21 and the driven wheel 22 being located directly below the mounting plate 60b, which causes the distance between the middle turntable 60a and the mounting plate 60b to be too large; the driving wheel 21 and the driven wheel 22 are tightly covered with a winding transmission member 23. For example, the driving wheel 21 and the driven wheel 22 are pulleys, and the transmission member 23 is a belt, so as to achieve the purpose of the horizontal turntable 20 driving the middle turntable 60a to rotate smoothly over a long distance. Of course, according to actual needs, the driving wheel 21 and the driven wheel 22 are each a sprocket, and correspondingly, the transmission member 23 is a chain, but it is not limited to this.

[0043] like Figure 5As shown, the clamping structure 61 includes a through hole 611 that passes through the middle turntable 60a from top to bottom and for the steel shell 200 to pass through, and a magnet 612 assembled on the middle turntable 60a. The magnet 612 magnetically attracts the steel shell 200 in the through hole 611 to keep the steel shell 200 in the through hole 611 in a penetrated state. In this way, the steel shell 200 clamped by the clamping mechanism 30 can be transferred to the clamping structure 61 more conveniently and quickly, and the clamping operation of the steel shell 200 by the clamping structure 61 is facilitated.

[0044] like Figures 2 to 5 As shown, the transfer mechanism 70 includes a cam plate 71 mounted on the frame 10 and located beside the horizontal turntable 20, an upper ejector 72 mounted on the frame 10 with its output end 721 facing upward, and an upper ejector head 73 mounted on the output end 721. The upper ejector head 73 is aligned with the steel shell 200 on the clamping mechanism 30 conveyed from the horizontal turntable 20; the cam plate 71 has an arc-shaped ejector structure 711 with its arc center located on the center line 24 of the horizontal turntable 20. One end of the arc-shaped ejector structure 711 extends to the feeding conveyor line 80c, and the other end of the arc-shaped ejector structure 711 extends to the fourth sealing mechanism 50d. The arc-shaped ejector structure 711 is used to eject the steel shell 200 on the horizontal turntable 20 that is rotated to the first sealing mechanism 50a. The clamping mechanism 30 between the first sealing mechanism 50d and the fourth sealing mechanism 50d is pushed, causing the clamping mechanism 30 to release its grip on the steel shell 200, thereby facilitating the loading mechanism 80d to place the steel shell 200 delivered by the loading conveyor line 80c into the clamping mechanism 30 adjacent to the first sealing mechanism 50a, and facilitating the upper ejector 73 to eject the steel shell 200 at the clamping mechanism 30 adjacent to the fourth sealing mechanism 50d into the aligned clamping structure 61 under the drive of the upper ejector driver 71. For example, the upper ejector driver 72 is a pneumatic cylinder, but may alternatively be a hydraulic cylinder depending on practical needs, but is not limited thereto. Simultaneously, the two ends of the arc-shaped ejector structure 711 extend obliquely away from the centerline 24 to form a linear avoidance structure 712. With the aid of the linear avoidance structure 712, the ejection wheel 34, described below, can more smoothly enter or exit the position of being pushed by the arc-shaped ejector structure 711 as it rotates with the horizontal turntable 20. In addition, regarding the specific structure of the clamping mechanism 30, see the following description.

[0045] like Figures 6 to 8As shown, the clamping mechanism 30 includes a base 31, a rotating ring 32 and three clamping blocks 33 arranged together along the rotation direction of the rotating ring 32 and capable of opening and closing and sliding along the radial direction of the rotating ring 32. The base 31 is assembled on the horizontal turntable 20 from above, so that the horizontal turntable 20 and the base 31 are fixed together; the rotating ring 32 is mounted on the base 31 so as to be horizontally rotatable from above the base 31, and the base 31 provides support for the rotation of the rotating ring 32; the rotating ring 32 is provided with a top wheel 34 located beside the outer side of the rotating ring 32, and the center line of the top wheel 34 is arranged along the up and down direction of the base 31. The top wheel 34 drives the rotating ring 32 to rotate relative to the base 31 under the push of the arc push structure 711, thereby avoiding the need for driving. The rotating ring 32 rotates and is independently powered; all the clamping blocks 33 are located in the space 321 surrounded by the rotating ring 32, so that the gap between the clamping blocks 33 and the rotating ring 32 is smaller, and each clamping block 33 is slidably mounted on the base 31 along the radial direction of the rotating ring 32 to ensure that the clamping blocks 33 slide stably on the base 31; the rotating ring 32 is provided with the same number of linked long holes 324 as the clamping blocks 33 and extending in an arc shape from the rotation center line 322 of the rotating ring 31 to the periphery 323 of the rotating ring 32, and each clamping block 33 is provided with a plurality of linked long holes 324 along the radial direction of the rotating ring 32. The base 31 is placed in the linkage long hole 324 in the up-down direction and the linkage boss 331 can slide along the linkage long hole 324; therefore, when the rotating ring 32 is driven to rotate by the top wheel 34, the rotating ring 32 drives all the clamping blocks 33 to open and slide through the cooperation of the linkage long hole 324 and the linkage boss 331, so as to correspondingly loosen the steel shell 200 clamped in the space 332 surrounded by all the clamping blocks 33, thereby facilitating the upper driving driver 72 to drive the upper ejector 73 upward to lift the clamping mechanism 30 adjacent to the fourth sealing mechanism 50d. The steel shell 200 is pushed into the through hole 611 of the middle turntable 60a, and the magnet 612 magnetically attracts the steel shell 200 pushed into the through hole 611. This also facilitates the feeding mechanism 80d to transfer the steel shell 200 to be sealed, which is delivered by the feeding conveyor line 80c, to the clamping mechanism 30 adjacent to the first sealing mechanism 50d. In addition, the rotating ring 32 drives all the clamping blocks 33 to open and close and slide, effectively ensuring that the position of the steel shell 200 after being clamped is the same each time, thereby ensuring the smooth transfer of the steel shell 200 to the clamping structure 61. Specifically, Figures 6 to 8In the embodiment, the clamping mechanism 30 further includes a spring 35, and the rotating ring 32 is provided with an arc guide hole 325 whose arc center is located on the rotation center line 322 of the rotating ring 32 and an assembly structure 326 located next to the arc guide hole 325. Preferably, the assembly structure 326 is a cylindrical structure to facilitate assembly operation with the spring 40. Of course, according to actual needs, the assembly structure 326 can also be other structures, so it is not limited to this; the base 31 is provided with a mounting post 311 that passes through the arc guide hole 325 upward along the up and down direction of the base 31 and can slide along the arc guide hole 325. Preferably, the mounting post 311 is a bolt post, so that the mounting post 311 passes through the arc guide hole 325 from the top of the rotating ring 32 downward during assembly and is then threadedly connected to the base 31, and the mounting post 311 also blocks the rotation The ring 32 slides upward relative to the base 31, effectively ensuring the reliability of the rotation of the rotating ring 32 relative to the base 31, and preventing the rotating ring 32 from moving relative to the base 31 along the up and down directions of the base 31 during the rotation process; the spring 35 is located above the rotating ring 32, one end of the spring 32 is assembled to the assembly structure 326, and the other end of the spring 35 is assembled to the mounting post 311. The spring 35 always has the tendency to rotate the rotating ring 32 to the initial position relative to the base 31. All the clamping blocks 33 are in a state of clamping the steel shell 200 when the rotating ring 32 switches to the initial position, so that the clamping force of the clamping blocks 33 on the steel shell 200 depends on the elastic force of the spring 35; in addition, the cooperation of the arc guide hole 325 and the mounting post 311 can also improve the smoothness and stability of the rotation of the rotating ring 32 relative to the base 31. More specifically, in Figures 6 to 9 In the embodiment, there are three arc guide holes 325 and they are arranged alternately with the linkage long holes 324 along the rotation direction of the rotating ring 32. Each arc guide hole 325 corresponds to a mounting post 311, an assembly structure 326 and a spring 35, so as to increase the clamping force of all clamping blocks 33 on the steel shell 200 and improve the smoothness of the rotating ring 32 automatically switching to the initial position. For example, in Figure 9 In the embodiment, the linkage slots 324 are arc-shaped slots that protrude away from the rotation centerline 322 of the rotating ring 32. This results in a greater linkage stroke than if the linkage slots 324 were protruded downwards and closer to the rotation centerline 322 of the rotating ring 32. Furthermore, the inner contours of all linkage slots 324 are tangent to the same inner circle 37, and the outer contours of all linkage slots 324 are tangent to the same outer circle 38. This design ensures that all linkage slots 324 have the same starting and ending positions along the radial direction of the rotating ring 32, thereby effectively utilizing the spatial position of the rotating ring 32. The more specific structure of the base 31 is described below.

[0046] like Figure 6 and Figure 7As shown, the base 31 includes an upper base 31a and a lower base 31b. The upper base 31a is provided with an escape space 312 that runs through it from top to bottom. The upper base 31a is also provided with a convex ring 313 that protrudes upward from the upper base 31a and is arranged around the escape space 312. The rotating ring 32 is fitted onto the outer surface of the convex ring 313 and is rotatably connected to the convex ring 313, thereby increasing the stability and smoothness of the rotational connection between the rotating ring 32 and the upper base 31a. The lower base 31b is assembled and connected to the upper base 31a, and the clamping block 33 is also located in the escape space 312, so that The design makes the distance between the clamping block 33 and the base 31 smaller; at the same time, the clamping mechanism 30 also includes sliders 36 clamped between the upper base 31a and the lower base 31b, and the number of the sliders 36 is the same as the clamping block 33. Each slider 36 is fixedly connected to a corresponding clamping block 33, so that the clamping block 33 can slide more steadily and smoothly on the base 31 with the help of the sliders 36; correspondingly, the linkage boss 331 is located on the slider 36, so that the rotating ring 32 is indirectly driven to slide. For example, in Figures 6 to 8 In the figure, the upper base 31a and the lower base 31b are each a rotating body, so that the cross-sectional profiles of the upper base 31a and the lower base 31b are circular, so as to facilitate the manufacturing and processing of the upper base 31a and the lower base 31b. Of course, according to actual needs, the upper base 31a and the lower base 31b can also be of other shapes, so this is not limited to it; all the clamping blocks 33 together form a complete rotating body after closing. This design makes it possible for the clamping blocks 33 located in the space 321 enclosed by the rotating ring 32 to have a smaller spacing from the rotating ring 32 while maintaining the same sliding stroke. Of course, according to actual needs, all the clamping blocks 33 together can form a structure of their shape after closing, so this is not limited to it.

[0047] like Figure 1 and Figure 10 As shown, the first sealing mechanism 50a includes a C-shaped mold frame 50a1, an electric push rod 50a2 and a sealing head 50a3. The C-shaped mold frame 50a1 is fixed to the frame 10 from above, and the frame 10 provides support for the C-shaped mold frame 50a1; the electric push rod 50a2 is installed on the C-shaped mold frame 50a1, and the output end 50a5 of the electric push rod 50a2 is arranged downward, and the sealing head 50a3 is installed on the output end 50a5 of the electric push rod 50a2.

Specifically, Figure 10In the figure, a leveling mechanism 90 is provided on opposite sides of the C-shaped mold frame 50a1. The leveling mechanism 90 includes a leveling bracket 91 fixed on the side wall of the C-shaped mold frame 50a1 and a leveling roller 92 assembled on the leveling bracket 91. The leveling roller 92 supports the horizontal turntable 20 from below and rolls along the rotation direction of the horizontal turntable 20. With the help of the cooperation between the leveling roller 92 and the leveling bracket 91, the horizontality of the horizontal turntable 20 is adjusted, thereby effectively ensuring the reliability of the first sealing mechanism 50a in sealing the steel shell 200.

[0048] like Figure 1 and Figure 11 As shown, the second sealing mechanism 50b includes a C-shaped mold frame 50b1, an electric push rod 50b2 and a sealing head 50b3. The C-shaped mold frame 50b1 is fixed to the frame 10 from above, and the frame 10 provides support for the C-shaped mold frame 50b1; the electric push rod 50b2 is installed on the C-shaped mold frame 50b1, and the output end 50b5 of the electric push rod 50b2 is arranged downward, and the sealing head 50b3 is installed on the output end 50b5 of the electric push rod 50b2. The C-shaped mold frame 50b1 is provided with a sealing structure 50b4 located directly below the sealing head 50b3; with the help of the electric push rod 50b2, parameter control and program control can be performed, so the sealing force is accurate and reliable. Specifically, Figure 11 In the figure, a leveling mechanism 90 is provided on opposite sides of the C-shaped mold frame 50b1. The leveling mechanism 90 includes a leveling bracket 91 fixed on the side wall of the C-shaped mold frame 50b1 and a leveling roller 92 assembled on the leveling bracket 91. The leveling roller 92 supports the horizontal turntable 20 from below and rolls along the rotation direction of the horizontal turntable 20. With the help of the cooperation between the leveling roller 92 and the leveling bracket 91, it is used to adjust the horizontality of the horizontal turntable 20, thereby effectively ensuring the reliability of the second sealing mechanism 50b in sealing the steel shell 200.

[0049] like Figure 1 and Figure 12 As shown, the third sealing mechanism 50c includes a C-shaped mold frame 50c1, an electric push rod 50c2 and a sealing head 50c3. The C-shaped mold frame 50c1 is fixed to the frame 10 from above, and the frame 10 provides support for the C-shaped mold frame 50c1; the electric push rod 50c2 is installed on the C-shaped mold frame 50c1, and the output end 50c5 of the electric push rod 50c2 is arranged downward, and the sealing head 50c3 is installed on the output end 50c5 of the electric push rod 50c2. The C-shaped mold frame 50c1 is provided with a sealing structure 50c4 located directly below the sealing head 50c3; with the help of the electric push rod 50c2, parameter control and program control can be performed, so the sealing force is accurate and reliable. Specifically, Figure 12Leveling mechanisms 90 are installed on opposite sides of the C-shaped mold frame 50c1. These mechanisms include leveling brackets 91 fixed to the side walls of the C-shaped mold frame 50b1 and leveling rollers 92 mounted on the brackets. The leveling rollers 92 support the horizontal turntable 20 from below and roll along the direction of rotation of the turntable 20. The leveling rollers 92 and the brackets 91 work together to adjust the horizontal turntable 20's levelness, effectively ensuring the reliability of the third sealing mechanism 50c in sealing the steel shell 200. More specifically, a pressure sensor is installed between the output end 50c5 of the electric push rod 50c2 of the third sealing mechanism 50c and the sealing head 50c3 to more accurately control the sealing force.

[0050] like Figure 1 and Figure 13 As shown, the fourth sealing mechanism 50d comprises a C-shaped mold frame 50d1, an electric push rod 50d2, and a sealing head 50d3. The C-shaped mold frame 50d1 is fixed to the frame 10 from above, with the frame 10 providing support for the C-shaped mold frame 50d1.

The electric push rod 50d2 enables parameter control and program control, ensuring precise and reliable sealing force. It should be noted that the sealing force of the electric push rods 50a2 (50b2, 50d2) of the first, second and fourth sealing mechanisms 50d is smaller than the sealing force of the electric push rod 50c2 of the third sealing mechanism 50c, but the present invention is not limited thereto.

[0051] In conjunction with the accompanying drawings, the working principle of the cylindrical power battery steel shell sealing machine 100 of the present invention is described as follows: the turntable driving mechanism 40 drives the horizontal turntable 20 along the Figure 1During the clockwise stepping rotation, any clamping mechanism 30 on the horizontal turntable 20 follows the horizontal turntable 20 to perform a rotational motion, and after each step of the horizontal turntable 20, the first sealing mechanism 50a, the second sealing mechanism 50b, the third sealing mechanism 50c, the upper ejector head 73 and the feeding mechanism 80d are aligned with a clamping mechanism 30 that rotates with the horizontal turntable 20, and the first sealing mechanism 50a performs the first sealing process on the steel shell 200, the second sealing mechanism 50b performs the second sealing process on the steel shell 200, and the third sealing mechanism 50c performs the third sealing process on the steel shell 200, and the upper ejector head 73 is driven by the upper ejector driver 72 to release the clamped steel shell 200. The shell 200 is pushed into the aligned clamping structure 61, and the loading mechanism 80d transfers the steel shell 200 transported by the loading conveyor line 80c into the corresponding clamping mechanism 30; wherein, when the steel shell 200 in the clamping structure 61 follows the turntable 60a to be transported to a position aligned with the fourth sealing mechanism 50d, the fourth sealing mechanism 50d seals the steel shell 200 for the fourth time, thereby completing the sealing process of the steel shell 200; when the steel shell 200 completes the sealing process and follows the turntable 60a to be transported to the bottom of the lower head 82, the lower head 82 is driven by the lower top driver 80a to push the steel shell 200 down to the unloading delivery line 80b, and then the unloading delivery line 80b transports the steel shell 200 outward. It should be noted that due to the setting of the arc pushing structure 711 of the cam plate 71, the clamping mechanism 30 opposite to the feeding mechanism 80d and the clamping mechanism 30 opposite to the upper head 73 are each pushed by the arc pushing structure 711, so that they are in a state of loosening the clamping steel shell 200.

[0052] Compared with the prior art, since the cylindrical power battery steel shell sealing machine 100 of the present invention also includes a central turntable 60a, a mounting plate 60b, a supporting stand 60c and a transfer mechanism 70, the central turntable 60a is located in front of the third sealing mechanism 50c along the rotation direction of the horizontal turntable 20, one side of the central turntable 60a is located directly above the horizontal turntable 20, and the other side opposite to the central turntable 60a protrudes from the horizontal turntable 20 along the radial direction of the horizontal turntable 20. The fourth sealing mechanism 50d is assembled on the frame 10 and is aligned with the position 62 where the central turntable 60a protrudes from the horizontal turntable 20, so that the fourth sealing mechanism 50d does not need to be arranged around the horizontal turntable 20 like the first to third sealing mechanisms 50c, so that the fourth sealing mechanism 50d can be away from the horizontal turntable 20 and maintain a larger distance from the third sealing mechanism 50c, thereby avoiding the fourth sealing mechanism 50d and the third sealing mechanism 50c from being too close to facilitate discharging. ; At the same time, since the middle turntable 60a is horizontally rotatably assembled on the mounting plate 60b and is transmission-connected to the horizontal turntable 20, the middle turntable 60a is provided with a plurality of clamping structures 61 for clamping the steel shell 200, which are arranged spaced apart along the rotation direction of the middle turntable 60a. Any clamping structure 61 selectively rotates to a position aligned with the fourth sealing mechanism 50d or the clamping mechanism 30 along the up and down direction of the frame 10 during the rotation of the middle turntable 60a, so as to ensure the reliability of the transfer mechanism 70 in transferring the steel shell 200 clamped by the clamping mechanism 30 on the horizontal turntable 20 to the clamping structure 61 of the middle turntable 60a; furthermore, with the help of the mounting plate 60b being located directly above the middle turntable 60a, the support stand 60c is assembled on the frame 10 and assembled and connected with the position where the middle turntable 60a protrudes from the horizontal turntable 20, thereby ensuring that the middle turntable 60a is reliably suspended on the horizontal turntable 20 and the fourth sealing mechanism 50d.

[0053] It is worth noting that the direction indicated by the arrow A in the accompanying drawings is the direction from top to bottom of the base 10, which is also the direction from top to bottom of the rack 10; in addition, although the accompanying drawings show three clamping blocks 33, of course, it can also be two, four or five blocks according to actual needs.

[0054] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are within the scope of the present invention.
