Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, in particular to a rolling device. Background Art

[0002] like Figure 1 and Figure 2 As shown, the rolling device in the related art usually includes a fixed roller 1a and a movable roller 1b. The ends of the fixed roller 1a and the movable roller 1b are both installed with a rotating bearing 1c, and the rotating bearing 1c is installed in the inner cavity of the bearing seat 1d. Among them, the bearing seat 1d of the fixed roller 1a is fixed to the supporting mechanism 1e of the rolling device and cannot move, while the bearing seat 1d of the movable roller 1b is slidably arranged on the guide rail 1j located on the supporting mechanism 1e through the slider 1f. Driven by the driving device 1h, the movable roller 1b can move on the guide rail 1j through the slider 1f, so as to adjust the roller gap and pressure between the fixed roller 1a and the movable roller 1b. However, this way of moving the movable roller 1b along the guide rail 1j will cause the movable roller 1b to move inflexibly, and there are problems such as large resistance to roller movement, unstable roller gap control and pressure control between rollers. Moreover, the moving roller 1b moves along the guide rail 1j by sliding friction or rolling friction. When driving devices 1h are provided at both ends of the moving roller 1b, due to the influence of processing and assembly, and there may be a power system at one end, it is difficult to make the resistance at both ends of the moving roller 1b consistent, which can easily cause the two bearing seats 1d to move inconsistently, resulting in the moving roller 1b not moving into place, resulting in poor repeatability and stability of the roller gap adjustment, and poor repeatability and stability of the pressure adjustment between the rollers.

[0035] like Figure 3 and Figure 4 As shown, a rolling device 10 provided by an embodiment of the utility model. The rolling device 10 includes a support mechanism 200, a first pressing roller mechanism 300 and a second pressing roller mechanism 400. The first pressing roller mechanism 300 includes a first mounting frame 310 provided on the support mechanism 200 and a first pressing roller 320 provided on the first mounting frame 310 and capable of rotating on the first mounting frame 310. The second pressing roller mechanism 400 includes a second mounting frame 410 provided on the support mechanism 200 and a second pressing roller 420 provided on the second mounting frame 410 and capable of rotating on the second mounting frame 410. The second pressing roller 420 is arranged in parallel with the first pressing roller 320 and a roller gap 10a is provided between the second pressing roller 420 and the first pressing roller 320. Among them, at least one of the first mounting frame 310 and the second mounting frame 410 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, so that at least one of the first pressing roller 320 and the second pressing roller 420 swings to adjust the size of the roller gap 10a.

[0036] When adjusting the size of the roller gap 10a, the above-mentioned rolling device 10 can control at least one of the first mounting frame 310 and the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, so that at least one of the first pressing roller 320 and the second pressing roller 420 swings to achieve the size adjustment of the roller gap 10a. That is, when the above-mentioned rolling device 10 adjusts the size of the roller gap 10a, the movement mode of the pressing roller changes from the traditional linear type to the swing type, which greatly reduces the movement resistance and improves the roller movement accuracy, so that the repeatability and stability of the roller gap 10a adjustment are greatly improved, and at the same time, the repeatability and stability of the pressure adjustment between the rollers are also greatly improved.

[0037] In this embodiment, the first pressing roller mechanism 300 further includes two first bearing members 330. The two first bearing members 330 are respectively arranged at both ends of the first pressing roller 320. The first bearing member 330 includes a first rotating bearing 332 and a first bearing seat 334. The first rotating bearing 332 is arranged on the first pressing roller 320. The first bearing seat 334 is sleeved outside the first rotating bearing 332 and is arranged on the first mounting frame 310. In this way, it is very convenient to realize that the first pressing roller 320 is arranged on the first mounting frame 310 and can rotate on the first mounting frame 310.

[0038] The second pressing roller mechanism 400 further includes two second bearing members 430. The two second bearing members 430 are respectively disposed at both ends of the second pressing roller 420. The second bearing member 430 includes a second rotating bearing 432 and a second bearing seat 434. The second rotating bearing 432 is disposed on the second pressing roller 420. The second bearing seat 434 is sleeved outside the second rotating bearing 432 and is disposed on the second mounting frame 410. In this way, it is very convenient to realize that the second pressing roller 420 is disposed on the second mounting frame 410 and can rotate on the second mounting frame 410.

[0039] In this embodiment, both the first mounting frame 310 and the second mounting frame 410 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a. In this way, the first mounting frame 310 and the second mounting frame 410 can simultaneously rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a. In this way, it is easier to adjust the size of the roll gap 10a.

[0040] In this embodiment, the support mechanism 200 is provided with a first rotating shaft 210 and a second rotating shaft 220. The first rotating shaft 210 and the second rotating shaft 220 both extend along the length direction of the roller gap 10a, and the first rotating shaft 210 and the second rotating shaft 220 are located on the same straight line. The first mounting frame 310 and the second mounting frame 410 are respectively provided on the first rotating shaft 210 and the second rotating shaft 220. The rotation center 10b includes the first rotating shaft 210 and the second rotating shaft 220. In this embodiment, the first rotating shaft 210 and the second rotating shaft 220 are disconnected and are two independent rotating shafts, so that it is more convenient to set the rotating shaft on the support mechanism 200. It can be understood that in other embodiments, the first rotating shaft 210 and the second rotating shaft 220 can also be the two ends of a rotating shaft.

[0041] In this embodiment, the rolling device further includes a driving mechanism 500. When the first mounting frame 310 or the second mounting frame 410 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, the driving mechanism 500 can drive the first mounting frame 310 or the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a. When both the first mounting frame 310 and the second mounting frame 410 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, the driving mechanism 500 can simultaneously drive the first mounting frame 310 and the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a. In this way, it is very convenient to automatically adjust the size of the roll gap 10a. It can be understood that in other embodiments, the driving mechanism 500 can also be omitted, and the size of the roll gap 10a can be adjusted manually.

[0042] In this embodiment, the driving mechanism 500 connects the first mounting frame 310 and the second mounting frame 410 . In this way, it is not only convenient to install the above-mentioned driving mechanism 500 and to simultaneously drive the first mounting frame 310 and the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, but also when the driving mechanism 500 drives the first mounting frame 310 (or the second mounting frame 410, or the first mounting frame 310 and the second mounting frame 410 simultaneously) to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, so that the first pressure roller 320 (or the second pressure roller 420, or the first pressure roller 320 and the second pressure roller 420 simultaneously) swings, the distance between the connection point of the driving mechanism 500 and the first mounting frame 310 (the first hinge mechanism 600) and the connection point of the driving mechanism 500 and the second mounting frame 410 (the second hinge mechanism 700) can be changed, so that the distance between the second pressure roller 420 and the first pressure roller 320 can be changed, that is, the size of the roller gap 10a can be changed. It can be understood that in other embodiments, the driving mechanism 500 can also be disposed on the supporting mechanism 200 .

[0043] In this embodiment, the driving mechanism 500 includes a driving body 510 and a telescopic member 520 connected to the driving body 510. The driving body 510 and the telescopic member 520 are respectively connected to the first mounting frame 310 and the second mounting frame 410. The driving body 510 can drive the telescopic member 520 to extend and retract. In this way, when the driving body 510 drives the telescopic member 520 to extend, the first mounting frame 310 (or the second mounting frame 410, or the first mounting frame 310 and the second mounting frame 410 at the same time) can be rotated on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, so that the first pressure roller 320 (or the second pressure roller 420, or the first pressure roller 320 and the second pressure roller 420 at the same time) swings, thereby increasing the distance between the connection point (first hinge mechanism 600) of the driving mechanism 500 and the first mounting frame 310 and the connection point (second hinge mechanism 700) of the driving mechanism 500 and the second mounting frame 410, thereby increasing the size of the roller gap 10a. When the driving body 510 drives the telescopic member 520 to contract, the first mounting frame 310 (or the second mounting frame 410, or the first mounting frame 310 and the second mounting frame 410 simultaneously) can be rotated on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a, so that the first pressure roller 320 (or the second pressure roller 420, or the first pressure roller 320 and the second pressure roller 420 simultaneously) swings, thereby reducing the distance between the connection point between the driving mechanism 500 and the first mounting frame 310 (the first hinge mechanism 600) and the connection point between the driving mechanism 500 and the second mounting frame 410 (the second hinge mechanism 700), thereby reducing the size of the roller gap 10a.

[0044] In this embodiment, the driving mechanism 500 may be an electric cylinder, a pneumatic cylinder or an oil cylinder.

[0045] In this embodiment, when the first mounting frame 310 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, the rolling device 10 further includes a first hinge mechanism 600. The driving mechanism 500 is connected to the first mounting frame 310 through the first hinge mechanism 600. In this way, it is possible to avoid the connection between the driving mechanism 500 and the first mounting frame 310 being a hard connection, so that when the driving mechanism 500 drives the first mounting frame 310 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, the first mounting frame 310 can be prevented from being damaged. It can be understood that in other embodiments, the first hinge mechanism 600 can also be omitted.

[0046] When the second mounting frame 410 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, the rolling device 10 further includes a second hinge mechanism 700, and the driving mechanism 500 is connected to the second mounting frame 410 through the second hinge mechanism 700. In this way, it is possible to avoid the connection between the driving mechanism 500 and the second mounting frame 410 being a hard connection, so that when the driving mechanism 500 drives the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a, it is possible to avoid damage to the second mounting frame 410. It is understood that in other embodiments, the second hinge mechanism 700 can also be omitted.

[0047] In this embodiment, the first mounting frame 310 includes a first bottom section 312 and a first top section 314. The first bottom section 312 and the first top section 314 are respectively located on both sides of the first pressing roller 320. The second mounting frame 410 includes a second bottom section 412 and a second top section 414. The second bottom section 412 and the second top section 414 are respectively located on both sides of the second pressing roller 420. The second bottom section 412 and the second top section 414 are respectively arranged corresponding to the first bottom section 312 and the first top section 314. At least one of the first bottom section 312 and the second bottom section 412 can rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roller gap 10a. The driving mechanism 500 connects the first top section 314 and the second top section 414. In this way, the driving mechanism 500 can be located on the side of the roller gap 10a away from the supporting mechanism 200d, so that there is a larger distance between the driving mechanism 500 and the rotation center 10b, and the first mounting frame 310 and / or the second mounting frame 410 can have a longer rotating arm, which makes it easier for the first mounting frame 310 and / or the second mounting frame 410 to rotate.

[0048] In some embodiments, Figure 5 As shown, the first pressing roller 320 is located at one end of the first mounting frame 310 away from the support mechanism 200. The second pressing roller 420 is located at one end of the second mounting frame 410 away from the support mechanism 200. The driving mechanism 500 is located between the roller gap 10a and the support mechanism 200. In this way, the driving mechanism 500 can have a smaller distance from the rotation center 10b, which makes it easier for the driving mechanism 500 to be stably arranged on the first mounting frame 310 and the second mounting frame 410.

[0049] In some embodiments, Figure 6 As shown, the driving mechanism 500 connects the first bearing seat 334 and the second bearing seat 434. In this way, the first mounting frame 310 and / or the second mounting frame 410 can have a longer rotating arm, which is more convenient for the first mounting frame 310 and / or the second mounting frame 410 to rotate, and the driving mechanism 500 can be stably arranged on the first mounting frame 310 and the second mounting frame 410.

[0050] In this embodiment, there are two drive mechanisms 500. The two drive mechanisms 500 are respectively located outside the two ends of the roll gap 10a. In this way, the forces on the two ends of the first mounting frame 310 and / or the second mounting frame 410 can be more uniform, the movement of the first mounting frame 310 and / or the second mounting frame 410 can be smoother, and the drive mechanism 500 can be prevented from interfering with the feeding and discharging of the roll gap 10a. It can be understood that in other embodiments, there can be only one drive mechanism 500.

[0051] In this embodiment, the rolling device 10 further includes a roll gap measuring mechanism and a control mechanism. The roll gap measuring mechanism can detect the actual size of the roll gap 10a. The control mechanism is respectively connected to the roll gap measuring mechanism and the drive mechanism 500 in communication. The control mechanism can store the preset size of the roll gap 10a and can compare the preset size of the roll gap 10a with the actual size of the roll gap 10a, and can control the drive mechanism 500 to drive at least one of the first mounting frame 310 and the second mounting frame 410 to rotate on the support mechanism 200 around the rotation center 10b parallel to the length direction of the roll gap 10a when the actual size is different from the preset size. In this way, the actual size of the roll gap 10a can be measured online, and then compared with the preset size of the roll gap 10a. If the actual size of the roll gap 10a is smaller, the drive mechanism 500 will be extended, thereby making the roll gap 10a larger. On the contrary, if the actual size of the roll gap 10a is larger than the preset size of the roll gap 10a, the drive mechanism 500 will be contracted, thereby making the roll gap 10a smaller. In this way, the roll gap measuring mechanism and the drive mechanism 500 form a closed loop, which can accurately control the size of the roll gap 10a.

[0052] In some embodiments, Figure 7 As shown, the number of at least one of the first pressing roller mechanism 300 and the second pressing roller mechanism 400 is greater than one, and the first pressing roller mechanism 300 and the second pressing roller mechanism 400 are arranged in an alternating manner. In this way, the above-mentioned rolling device 10 is a multi-roller rolling device, so that the above-mentioned rolling device 10 can have a wider range of application scenarios. Specifically, in this embodiment, there are two first pressing roller mechanisms 300 and one second pressing roller mechanism 400. It can be understood that in other embodiments, the number of both the first pressing roller mechanism 300 and the second pressing roller mechanism 400 can be greater than or equal to two.

[0053] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention.
