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 As shown, the multi-roller side-by-side rolling system usually includes at least one fixed roller (roller position is fixed) 1a and at least one movable roller 1b (mounted on a guide rail). Rotating bearings are installed at the ends of the fixed roller 1a and the movable roller 1b, and the rotating bearings are installed in the inner cavity of the bearing seat 1c. There is a roller gap adjustment device 1d between the bearing seats 1c to control the spacing between two adjacent rollers. The roller gap adjustment device 1d is generally a wedge block, or other types of fine-tuning spacing devices. Two driving devices 1e are installed on the left side of the multi-roller side-by-side rolling system. When the driving device 1e is working, it pushes the bearing seat 1c of the movable roller 1b to press against the roller gap adjustment device 1d. In this structure, the gap between the rollers can be controlled by the roller gap adjustment device 1d between the two rollers, but the pressure between the roller gaps in this structure cannot be accurately controlled.

[0003] When the above multi-roller side-by-side rolling system is working, the material enters the roller gap 1f, the force applied by the driving device 1e on the left is F, the pressure on the bearing seat 1c of the second roller (the roller in the middle) is F1, the pressure on the bearing seat 1c of the third roller (the roller on the far right) is F2, the pressure between the first roller (the roller on the far left) and the second roller is f1 (force transmitted through the material in the roller gap), and the pressure between the second roller and the third roller is f2. According to the principle of interaction force, the following formula is established: 2F = 2F1 + f1 = 2F2 + f2. That is, when the total pressure 2F of the multi-roller side-by-side rolling system is transmitted to the roller gap, it is divided into two parts, one part is transmitted to the bearing seat 1c as 2F1, 2F2, and the other part is the roller pressure f1, f2 we need. Roller pressures f1 and f2 cannot be directly set and controlled on the multi-roller side-by-side rolling system. Utility Model Content

[0019] The driving mechanism can also enable one of the two roller mechanisms to move toward the other roller mechanism to adjust the roller gap between two adjacent rollers.

At the same time, when designing the frame, it is not necessary to consider whether the strength of the frame can withstand the force applied by the driving mechanism.

[0032] like Figure 2 As shown, a rolling device 10 provided by an embodiment of the utility model. The rolling device 10 includes a rolling mechanism 200 and a driving mechanism 300. The rolling mechanism 200 includes a rotatable rolling roller 210. There are multiple rolling mechanisms 200. The multiple rolling mechanisms 200 are arranged in parallel, and there is a roller gap 210a between two adjacent rolling rollers 210. The driving mechanism 300 connects two adjacent rolling mechanisms 200. The driving mechanism 300 can make one of the two rolling mechanisms 200 apply force to the other rolling mechanism 200 and make the applied force the roller pressure between the two adjacent rolling rollers 210.

[0033] In the above rolling device 10, the driving mechanism 300 connects two adjacent roller mechanisms 200, and the driving mechanism 300 can make one of the two roller mechanisms 200 apply force to the other roller mechanism 200 and make the applied force the roller pressure between the two adjacent rollers 210, so that the roller pressure between the rollers 210 of the two adjacent roller mechanisms 200 connected by the driving mechanism 300 can be directly obtained. Figure 1 The driving device 1e shown is an external force transmission method that transmits force through the roller gap adjustment device 1d between two adjacent roller mechanisms (only a part of the force applied by the driving device 1e is converted into the roller pressure between the rollers of the two adjacent roller mechanisms, and the roller pressure cannot be directly obtained). The above-mentioned rolling device 10 connects the two adjacent roller mechanisms 200 through the driving mechanism 300, so that the force applied by one roller mechanism 200 of the two roller mechanisms 200 to the other roller mechanism 200 is an internal force. The force applied by the driving mechanism 300 to the other roller mechanism 200 through one roller mechanism 200 is the roller pressure between the rollers 210 of the two adjacent roller mechanisms 200 connected by the driving mechanism 300, and the roller pressure between the rollers 210 of the two adjacent roller mechanisms 200 connected by the driving mechanism 300 can be directly obtained.

[0034] Moreover, in the above-mentioned rolling device 10, the force applied by one of the two rolling mechanisms 200 to the other rolling mechanism 200 is an internal force, and the force applied by the driving mechanism 300 will not be transmitted to the surrounding rolling mechanisms 200, nor will it be transmitted to the frame 400 (such as the frame 400) of the rolling device 10 for mounting the rolling mechanisms 200. Figure 3 and Figure 4As shown), the roller pressure between the rollers 210 of two adjacent roller mechanisms 200 can be set separately. At the same time, when designing the frame 400, it is not necessary to consider whether the strength of the frame 400 can withstand the force applied by the driving mechanism 300. The strength of the frame 400 only needs to meet the installation requirements of the roller mechanism 200. Therefore, a frame 400 with lower strength can be used, thereby reducing the cost of the frame 400.

[0035] In this embodiment, the driving mechanism 300 includes a driving unit 300a. The driving unit 300a is located between the ends of two adjacent roller mechanisms 200 and outside the ends of the roller gaps 210a corresponding to the two roller mechanisms 200. The driving unit 300a connects the two adjacent roller mechanisms 200, and the driving unit 300a can enable one of the two roller mechanisms 200 to apply force to the other roller mechanism 200 and make the applied force at least part of the roller pressure between the two adjacent rollers 210. When the driving mechanism 300 includes only one driving unit 300a, the driving unit 300a can enable one of the two roller mechanisms 200 to apply force to the other roller mechanism 200 and make the applied force the entire roller pressure between the two adjacent rollers 210. When the driving mechanism 300 includes a plurality of driving units 300a, each driving unit 300a can make one of the two roller mechanisms 200 apply force to the other roller mechanism 200 and make the applied force be a partial roller pressure between two adjacent rollers 210, and the sum of the plurality of partial roller pressures is the total roller pressure. The driving mechanism 300 applies force through the driving unit 300a, and the driving unit 300a is located between the ends of the two adjacent roller mechanisms 200 and outside the ends of the roller gap 210a corresponding to the two roller mechanisms 200, which is very convenient to realize that one of the two roller mechanisms 200 applies force to the other roller mechanism 200 and makes the applied force be the roller pressure between the two adjacent rollers 210. It can be understood that in other embodiments, the driving unit 300a can also be located at the ends of the roller gap 210a and connect the two adjacent rollers 210.

[0036] In this embodiment, the driving mechanism 300 includes two driving units 300a. In the roller gap 210a corresponding to the driving mechanism 300, the two driving units 300a are respectively located outside the two ends of the roller gap 210a. In this way, one of the two roller mechanisms 200 can apply force to the two ends of the other roller mechanism 200 through the two driving units 300a, so that the roller pressure between the two adjacent rollers 210 is more uniform. Moreover, the arrangement of two driving units 300a can simplify the structure of the driving mechanism 300 relative to the arrangement of more driving units 300a. It can be understood that in other embodiments, only one driving unit 300a can be arranged. In this case, in order to make the roller pressure between the two adjacent rollers 210 more uniform, the driving unit 300a can be arranged in the middle of the two adjacent rollers 210. It can be understood that in other embodiments, four, six or more driving units 300a can also be arranged.

[0037] In this embodiment, if Figure 2-Figure 4 As shown, the roller mechanism 200 also includes two bearing members 220. Both ends of the roller 210 have a rotating shaft portion 212. The two bearing members 220 are respectively arranged on the two rotating shaft portions 212 of the roller 210. Among them, the bearing member 220 includes a rotating bearing 222 and a bearing seat 224. The rotating bearing 222 is arranged on the rotating shaft portion 212. The bearing seat 224 is sleeved outside the rotating bearing 222. In this way, it is very convenient to realize that the roller mechanism 200 includes a rotatable roller 210. The driving unit 300a is located between two adjacent bearing seats 224 and connected to the two adjacent bearing seats 224. In this way, it is very convenient to install the driving unit 300a.

[0038] In this embodiment, at least one of the two roller mechanisms 200 connected by the driving mechanism 300 is a mobile roller mechanism 200a. The mobile roller mechanism 200a can move in the direction in which the multiple roller mechanisms 200 are arranged in parallel. The driving mechanism 300 can also make one of the two roller mechanisms 200 move toward the other roller mechanism 200 to adjust the roller gap 210a between two adjacent rollers 210. In this way, the working mode of the above-mentioned rolling device 10 can include both a force control mode and a displacement control mode.

[0039] In the force control mode, when the above-mentioned rolling device 10 is working, the telescopic member 320 can be controlled to be telescopic through the driving body 310 first, so that the width of the roller gap 210a is at a preset width, and then the roller mechanism 200 connected to the driving body 310 applies a constant force to the roller mechanism 200 connected to the telescopic member 320 through the driving body 310 and the telescopic member 320. When the amount of material passing through the roller gap 210a is different, the thickness of the obtained product will be different. The more the amount of material passing through the roller gap 210a, the greater the thickness of the product, and the less the amount of material passing through the roller gap 210a, the smaller the thickness of the product, but the force per unit volume of the material is the same and the density is consistent.

[0040] In the displacement control mode, when the roller pressing device 10 is working, the telescopic member 320 is controlled to be telescopic by the driving body 310 so that the width of the roller gap 210a is at a preset width. When the amount of material passing through the roller gap 210a is different, the density of the obtained product will be different. The more the amount of material passing through the roller gap 210a, the greater the density of the product. The less the amount of material passing through the roller gap 210a, the smaller the density of the product, but the thickness of the product will be consistent.

[0041] In this embodiment, the driving unit 300a includes a driving body 310 and a telescopic member 320 connected to the driving body 310. The driving body 310 and the telescopic member 320 are respectively connected to two adjacent bearing seats 224. The driving body 310 can apply force through the telescopic member 320 and can drive the telescopic member 320 to extend and retract. In this way, it is very convenient to realize that the working mode of the above-mentioned rolling device 10 has both a force control mode and a displacement control mode.

[0042] In this embodiment, the driving unit 300a is a servo oil cylinder or a servo electric cylinder. It is understood that in other embodiments, the driving unit 300a can also be other mechanisms that can enable one of the two roller mechanisms 200 to apply force to the other roller mechanism 200.

[0043] In this embodiment, the number of the driving mechanisms 300 is the same as the number of the roller gaps 210a and they are arranged one to one. In this way, the roller pressure between any two adjacent rollers 210 can be controlled separately. It is understood that in other embodiments, the number of the driving mechanisms 300 can also be less than the number of the roller gaps 210a.

[0044] In this embodiment, in the direction in which the plurality of roller mechanisms 200 are arranged in parallel, one of the two roller mechanisms 200 located at the outermost sides is a fixed roller mechanism 200b, and the other roller mechanisms 200 are all mobile roller mechanisms 200a. The mobile roller mechanism 200a can move in the direction in which the plurality of roller mechanisms 200 are arranged in parallel. In this way, the roller gap 210a between any two adjacent rollers 210 can be controlled separately. It can be understood that in other embodiments, any one of the roller mechanisms 200 can be a fixed roller mechanism 200b, and the other roller mechanisms 200 can move away from or close to the fixed roller mechanism 200b.

[0045] In this embodiment, the rolling device 10 includes three roller mechanisms 200. The three roller mechanisms 200 include two movable roller mechanisms 200a and one fixed roller mechanism 200b. It can be understood that in other embodiments, the rolling device 10 may also include two roller mechanisms 200 or four or more roller mechanisms 200.

[0046] In this embodiment, between two adjacent bearing seats 224, the driving body 310 is connected to the bearing seat 224 close to the fixed roller mechanism 200b, and the telescopic member 320 is connected to the bearing seat 224 far from the fixed roller mechanism 200b. In this way, the driving unit 300a can apply a pulling force toward the fixed roller mechanism 200b when applying force, so that the rolling device 10 is a contraction type rolling device.

[0047] like Figure 2 As shown, in this embodiment, the driving mechanism 300 includes two driving units 300a. When the driving unit 300a between the two movable roller mechanisms 200a sets the tension to F1, the roller pressure f1 between the two adjacent rollers 210 is equal to 2F1. When the driving unit 300a between the movable roller mechanism 200a and the fixed roller mechanism 200b sets the tension to F2, the roller pressure f2 between the two adjacent rollers 210 is equal to 2F2. Therefore, the driving mechanism 300 can make one of the two roller mechanisms 200 apply force to the other roller mechanism 200 and make the applied force the roller pressure between the two adjacent rollers 210.

[0048] In this embodiment, the rolling device 10 further includes a frame 400. A guide rail 500 is provided on the frame 400. A slider 600 is provided on the bearing seat 224 of the movable roller mechanism 200a. The movable roller mechanism 200a is provided on the frame 400 through the guide rail 500 and the slider 600. The bearing seat 224 of the fixed roller mechanism 200b is provided on the frame 400.

[0049] In this embodiment, the rolling device 10 further includes a switching mechanism. The switching mechanism can control the driving mechanism 300 to switch between a force control mode and a displacement control mode. In the force control mode, the driving mechanism 300 causes one of the two roller mechanisms 200 to apply force to the other roller mechanism 200 and causes the applied force to be a roller pressure between two adjacent rollers 210. In the displacement control mode, the driving mechanism 300 causes one of the two roller mechanisms 200 to move toward the other roller mechanism 200 to adjust the roller gap 210a between the two adjacent rollers 210.

[0050] The utility model also provides a coating machine. The coating machine includes the above-mentioned roller pressing device 10. That is, the above-mentioned roller pressing device 10 is applied to the coating machine for producing electrode sheets. It can be understood that in other embodiments, the above-mentioned roller pressing device 10 can also be applied to other technical fields.

[0051] like Figure 5 As shown, the utility model also provides a rolling method, comprising the following steps:

[0052] Step S710, providing the above-mentioned rolling device.

[0053] Step S720, rolling the material passing through the roller gap between two adjacent roller mechanisms through the force control mode of the driving mechanism, wherein the force control mode of the driving mechanism is that the driving mechanism causes one of the two roller mechanisms to apply force to the other roller mechanism and causes the applied force to be the roller pressure between the two adjacent rollers.

[0054] The roller compaction method described above can be used to produce a product with a consistent density.

[0055] In this embodiment, before performing step S720, a step of adjusting the roller gap between two adjacent roller mechanisms by a driving mechanism is also included.

[0056] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
