Description

Technical Field

[0001] The present application belongs to the field of battery processing technology, and more specifically, relates to a rolling device and a rolling machine. Background Art

[0002] During the power battery manufacturing process, lasers are used to seal the battery case and cover after the battery cell is placed in the shell. The varying sizes of the molten pool produced by laser welding create uneven welds, making them prone to puncturing the film during subsequent encapsulation.

[0003] To address this issue, a rolling device is currently used to flatten the battery welds. Because the welds of different battery sizes vary in size and shape, a rolling roller is typically configured with an adjustable angle to adjust the orientation of the rolling surface, ensuring it consistently aligns with the weld. However, the conventional rolling device is difficult to adjust, increasing commissioning time. Utility Model Content

[0041] See also Figure 2 and Figure 3 An embodiment of the present application provides a rolling device 100 , including a mounting base 10 , a pressure wheel assembly 20 , a driving assembly 30 and a connecting rod assembly 40 .

[0042] The pressing wheel assembly 20 can be rotatably mounted on the mounting base 10. The pressing wheel assembly 20 includes a roller for pressing the Figure 1 3. The rolled surface 21 of the weld 310 of the workpiece 300 is shown in FIG. The driving assembly 30 is in transmission connection with one end of the connecting rod assembly 40 to drive the one end of the connecting rod assembly 40 to move linearly in a first direction. The other end of the connecting rod assembly 40 is rotatably connected to the pressure wheel assembly 20 to drive the pressure wheel assembly 20 to rotate to adjust the direction of the rolled surface 21.

[0043] Here, "adjusting the orientation of the rolling surface 21" refers to adjusting the direction of pressure applied by the rolling surface 21 to the weld 310. By adjusting the orientation of the rolling surface 21, the rolling surface 21 can be kept in constant contact with the weld 310, thus accommodating welds 310 of varying sizes and shapes. It is understood that the workpiece 300 can be a battery casing, and after the battery casing and the cover plate are welded, the pressure roller assembly 20 can be used to roll the weld 310.

[0044] Among them, see Figure 2 , the “first direction” can be represented by the X-axis.

[0045] The working principle of the rolling device 100 of the embodiment of the present application is as follows:

[0046] When the direction of the rolling surface 21 needs to be adjusted, the driving assembly 30 first drives one end of the connecting rod assembly 40 to move linearly along the first direction, and the other end of the connecting rod assembly 40 drives the pressure wheel assembly 20 to rotate, thereby achieving the direction adjustment of the rolling surface 21.

[0047] The rolling device 100 provided in the embodiment of the present application is achieved by rotatably mounting the pressure wheel assembly 20 on the mounting base 10, and utilizing the driving assembly 30 to drive one end of the connecting rod assembly 40 to perform linear motion along a first direction. Since the other end of the connecting rod assembly 40 is rotatably connected to the pressure wheel assembly 20, the pressure wheel assembly 20 can be driven to rotate, thereby adjusting the orientation of the rolling surface 21. The adjustment is simple and convenient, which can effectively reduce the debugging time. In addition, the setting of the connecting rod assembly 40 makes the overall structure more stable and reliable, and the adjustment accuracy is higher, thereby improving the rolling yield.

[0048] See also Figure 6 The connecting rod assembly 40 may include a slider 41 and a connecting rod 42. The slider 41 is movably mounted on the mounting base 10 in a first direction. The driving assembly 30 is in transmission connection with the slider 41, thereby driving the slider 41 to move in the first direction. One end of the connecting rod 42 is rotatably connected to the slider 41, and the other end of the connecting rod 42 is rotatably connected to the pressure roller assembly 20. The provision of the connecting rod 42 converts the linear motion of the slider 41 into the rotational motion of the pressure roller assembly 20, thereby driving the pressure roller assembly 20 to rotate and adjust the orientation of the rolling surface 21. The coordination between the slider 41 and the connecting rod 42 makes the overall structure more stable and reliable.

[0049] See also Figure 4 and Figure 5 The mounting seat 10 may be provided with a chute 11 extending along the first direction. The slider 41 is slidably mounted in the chute 11. By providing the chute 11, the slider 41 moves along the chute 11, and its movement accuracy is higher.

[0050] See also Figure 5 and Figure 6The drive assembly 30 may include an adjustment screw rotatably mounted on the mounting base 10, and the slider 41 is threadedly connected to the adjustment screw. By rotating the adjustment screw, the slider 41 slides along the slide groove 11, thereby rotating the connecting rod 42, which makes adjustment very simple and convenient. Of course, the configuration of the drive assembly 30 is not limited to this. For example, in other embodiments of the present application, the drive assembly 30 may also be a linear motor or a linear cylinder, or a rotary motor or a rotary cylinder in combination with a transmission module that can convert the rotational driving force of the rotary motor or rotary cylinder into the linear motion of the slider 41.

[0051] The driving assembly 30 may further include a locking member (not shown). After the adjusting screw is adjusted, the locking member is connected and fixed to the adjusting screw, thereby locking the adjusting screw so that the orientation of the rolling surface 21 is maintained at a specified angle.

[0052] See also Figure 6 The rolling device 100 may further include a first locking member 50 and a second locking member 60. After the adjustment screw is adjusted, the first locking member 50 and the second locking member 60 are respectively threadedly connected to the adjustment screw, with the first locking member 50 abutting one side of the slider 41, and the second locking member 60 abutting the other side of the slider 41. The provision of the first locking member 50 and the second locking member 60 prevents the slider 41 from loosening, thereby improving the stability of the slider 41. Specifically, the first locking member 50 and the second locking member 60 may be lock nuts.

[0053] See also Figure 2 and Figure 3 The rolling device 100 may further include a base 70 and a drive mechanism 80. The drive mechanism 80 is disposed on the base 70. The drive mechanism 80 is in transmission connection with the mounting base 10 to drive the mounting base 10 to move in a first direction so that the rolling surface 21 approaches or moves away from the weld 310 of the workpiece 300.

[0054] When the weld 310 of the workpiece 300 needs to be rolled, the drive mechanism 80 can first drive the mounting base 10 to move in a first direction, thereby driving the rolling surface 21 of the pressure wheel assembly 20 to approach the weld 310 of the workpiece 300. Then, the workpiece 300 is driven to move, and the weld 310 of the workpiece 300 just abuts the rolling surface 21, thereby shaping the weld 310 of the workpiece 300. Specifically, the drive mechanism 80 can be a linear motor or linear motor, or a rotary motor or rotary cylinder, and can be equipped with a transmission module that can convert the rotational driving force of the rotary motor or rotary cylinder into the linear motion of the slider 41.

[0055] See also Figure 2 and Figure 3The rolling device 100 may further include a guide rail 90 and a movable block 91. The guide rail 90 is disposed on the base 70. The movable block 91 is connected to the mounting seat 10. The cooperation between the movable block 91 and the guide rail 90 can improve the accuracy of the movement of the mounting seat 10 along the first direction.

[0056] See also Figure 2 and Figure 3 The rolling device 100 may also include a dust removal pipe 92 and a dust removal brush 93. The dust removal pipe 92 is mounted on the mounting base 10, with the dust suction port of the dust removal pipe 92 facing the rolling surface 21. The dust removal brush 93 is positioned within the dust suction port of the dust removal pipe 92 and in contact with the rolling surface 21. The dust removal brush 93 removes dust from the rolling surface 21 and absorbs it through the dust removal pipe 92, thereby ensuring the cleanliness of the rolling surface 21 and improving the rolling effect.

[0057] See also Figure 4 and Figure 5 The rolling device 100 may further include a rotating shaft 94 and an angle encoder 95. The rotating shaft 94 is rotatably mounted on the mounting base 10, with one end of the rotating shaft 94 connected to the pressing wheel assembly 20, and the other end of the rotating shaft 94 connected to the angle encoder 95. By providing the angle encoder 95, the rotation angle of the pressing wheel assembly 20 can be detected in real time to ensure the rolling effect.

[0058] See also Figure 6 The rolling device 100 may further include an angle pointer 96. The angle pointer 96 is provided on the pressure roller assembly 20, and the mounting base 10 is provided with an angle scale line (not shown in the figure). Through the cooperation of the angle pointer 96 and the angle scale line, the rotation angle of the pressure roller assembly 20 can be conveniently and intuitively observed.

[0059] See also Figure 6 The pressure roller assembly 20 may include a support base 22 and a pressure roller 23. The support base 22 is rotatably mounted on the mounting base 10 and is rotatably connected to the other end of the connecting rod assembly 40. The pressure roller 23 is rotatably mounted on the support base 22. When the driving assembly 30 drives one end of the connecting rod assembly 40 to move in the first direction, the connecting rod assembly 40 simultaneously drives the support base 22 to rotate, thereby adjusting the direction of the rolling surface 21.

[0060] See also Figure 1 An embodiment of the present application also provides a roller press, comprising a support frame 200, and two roller pressing devices 100 spaced apart along a first direction on the support frame 200, at least one of the two roller pressing devices 100 is the roller pressing device 100 in any of the above embodiments.

[0061] The working principle of the roller press in the embodiment of the present application is as follows:

[0062] First, the distance between the two rolling devices 100 is adjusted so that the distance between the two rolling devices 100 is slightly smaller than the size of the workpiece 300 along the first direction;

[0063] Next, the workpiece 300 passes between the two rolling devices 100 . At this time, the rolling surface 21 of the pressing wheel assembly 20 squeezes the weld 310 of the workpiece 300 , thereby shaping the weld 310 .

[0064] Since the roller press of the embodiment of the present application includes the roller pressing device 100 in any of the above embodiments, it has the beneficial effects brought by the roller pressing device 100 in any of the above embodiments, which will not be described in detail here.

[0065] See also Figure 1 and Figure 3 The roller press can further include a connecting member (not shown). At least one roller press device 100 is provided with a through hole 71. The support frame 200 is provided with a plurality of connecting holes 210 spaced apart along the first direction. The connecting member passes through the through hole 71 and connects to any of the connecting holes 210. The arrangement of the connecting member and the connecting holes 210 allows the position of the roller press device 100 to be adjusted along the first direction, thereby accommodating the roller press of workpieces 300 of varying sizes. Specifically, the connecting member can be an adjustment screw, and the connecting hole 210 can be a threaded hole.
