[0002] Wafer making is an important step in the battery stacking production process. Wafer making usually involves cutting continuous electrode strips into single electrode sheets. In the process of cutting the electrode strips, a large amount of dust will be generated. The dust will not only pollute the factory environment, but also adhere to the single electrode sheets and the electrode strips, thus affecting the processing quality of the single electrode sheets. In the prior art, a dust removal mechanism is usually set up to absorb the dust generated during the wafer making process. However, in order to ensure that all the dust generated during the mobile cutting process is completely absorbed, it is usually necessary for the dust removal mechanism to cover the entire path of the mobile cutting. The entire dust removal mechanism needs to be connected to the air pressure dust removal. When the ventilation pressure cannot be guaranteed, the dust removal effect of the dust removal mechanism cannot be guaranteed. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0028] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.
[0029] According to an embodiment of the utility model, on the one hand, a film-making device is provided, comprising a film-making table 1, a mobile cutting mechanism 2 and a dust removal mechanism 3. The film-making table 1 is suitable for carrying a pole piece strip, and the mobile cutting mechanism 2 is movably arranged above the film-making table 1, and the mobile cutting mechanism 2 is suitable for cutting the pole piece strip on the film-making table 1 into a pole piece during movement. At least part of the dust removal mechanism 3 and the mobile cutting mechanism 2 can be synchronously moved and arranged, so that the dust removal mechanism 3 and the cutting position of the mobile cutting mechanism 2 are arranged correspondingly.
[0030] At least part of the dust removal mechanism 3 is movably arranged so that at least part of the dust removal mechanism 3 can move synchronously with the mobile cutting mechanism 2, so that the dust removal mechanism 3 can always perform dust removal corresponding to the cutting position of the mobile cutting mechanism 2. The overall volume of the dust removal mechanism 3 is reduced, and the air pressure at various locations of the dust removal mechanism 3 is easy to ensure, thereby ensuring the dust removal effect of the dust removal mechanism 3.
[0031] It is worth noting that in the related art, the dust removal mechanism 3 is usually made to cover the entire path of mobile cutting. Compared with the dust removal mechanism 3 of this embodiment, if the two dust removal mechanisms 3 are to achieve the same dust removal effect, the dust removal mechanism 3 of the related art requires a greater ventilation pressure (positive pressure for blowing dust and / or negative pressure for suction dust), resulting in a waste of resources.
[0032] In one embodiment, Figures 1 to 4 As shown, the mobile cutting mechanism 2 includes a first driving structure 201 and a cutting structure 202 , and the first driving structure 201 is suitable for driving the cutting structure 202 to move along the film-making table 1 .
[0033] It is worth mentioning that please refer to Figure 2 , the first driving structure 201 can drive the cutting structure 202 to move back and forth in the left and right directions. Specifically, when the first driving structure 201 drives the cutting structure 202 to move to the right, the cutting structure 202 cuts the pole piece strip, and the dust removal mechanism 3 moves with the cutting structure 202, and the dust removal mechanism 3 is in an open state to achieve dust removal; when the cutting structure 202 moves to the right and is in place, the cutting is completed. The first driving structure 201 drives the cutting structure 202 to move to the left for a return journey, and can return at a medium speed or a fast speed during the return journey. The dust removal mechanism 3 follows the cutting structure 202 in the return journey, and the dust removal mechanism 3 can remain in an open state or be closed to save resources; or, the pole piece strip can continue to be cut and produced during the return journey, and the dust removal mechanism 3 remains in an open state during the return journey of the cutting structure 202 to continuously remove dust.
[0034] In one embodiment, Figures 1 to 4As shown, the film-making device further includes a fixed table 5, and the film-making table 1 is arranged on the fixed table 5. Further, the film-making device further includes a bracket 6, the lower end of the bracket 6 is connected to the fixed table 5, the upper end of the bracket 6 is arranged higher than the film-making table 1, the first driving structure 201 is arranged corresponding to the upper end of the bracket 6, the first driving structure 201 is transmission-connected with the cutting structure 202, and the cutting structure 202 extends out of the bracket 6 and corresponds to the upper surface of the film-making table 1.
[0035] In order to enable the dust removal mechanism 3 to move synchronously with the cutting structure 202, this embodiment provides the following two implementation methods.
[0036] In the first embodiment, the dust removal mechanism 3 is connected to the cutting structure 202. When the first driving structure 201 drives the cutting structure 202 to move and cut the electrode strip, the first driving structure 201 can simultaneously drive the dust removal mechanism 3 to move, ensuring that the cutting structure 202 and the dust removal mechanism 3 move synchronously, so that the dust removal mechanism 3 always corresponds to the cutting position of the cutting structure 202.
[0037] In a second embodiment, if Figure 2 As shown, the film-making device further includes a second driving structure 4, which is in driving connection with the dust removal mechanism 3, and the first driving structure 201 and the second driving structure 4 are suitable for driving the cutting structure 202 and the dust removal mechanism 3 to move synchronously. The cutting structure 202 and the dust removal mechanism 3 are driven by the first driving structure 201 and the second driving structure 4 respectively, so that the first driving structure 201 and the second driving structure 4 are driven synchronously, and the cutting structure 202 and the dust removal mechanism 3 can be moved synchronously.
[0038] It is worth noting that since the position accuracy requirement for the cutting structure 202 is high, but there is no high requirement for the position accuracy of the dust removal mechanism 3, in the second embodiment, the first driving structure 201 can adopt a high-precision driving structure, and the second driving structure 4 can adopt a medium-to-low-precision driving structure.
[0039] In a second embodiment, if Figure 2 As shown, the second driving structure 4 is disposed on the bracket 6 .
[0040] In one embodiment, Figures 1 to 5 As shown, the dust removal mechanism 3 includes a dust hood 301 and an air knife 302, which are arranged opposite to each other and are arranged on opposite sides of the film-making table 1, and are both suitable for synchronous movement with the mobile cutting mechanism 2. The dust hood 301 and the air knife 302 are arranged opposite to each other, and the dust hood 301 is connected to negative pressure for dust removal, and the air knife 302 is connected to positive pressure for dust blowing, so as to improve the dust removal effect.
[0041] It is worth mentioning that please refer to Figure 2 and Figure 3 The cutting structure 202 , the dust hood 301 and the wind knife 302 are suitable for synchronous movement along the length direction of the film-making table 1 , and the dust hood 301 and the wind knife 302 are relatively spaced apart along the width direction of the film-making table 1 .
[0042] It should be noted that the dust hood 301 is connected to a dust collector or a centralized dust removal system through a dust removal pipeline, and the dust collector or the centralized dust removal system provides negative pressure and dust suction flow. The wind knife 302 is connected to a positive pressure air pipe, and the positive pressure air pipe provides compressed air and the required flow, and the gas wind speed can be controlled and adjusted by the debugging valve of the wind knife 302.
[0043] In one embodiment, Figure 1 and Figure 5 As shown, the dust removal mechanism 3 also includes a connecting structure 303, which spans across the two opposite sides of the film-making table 1 and connects the dust hood 301 and the wind knife 302. The dust hood 301 and the wind knife 302 are connected through the connecting structure 303, so that the dust hood 301 and the wind knife 302 can move synchronously, thereby ensuring the coordination effect of the dust hood 301 and the wind knife 302.
[0044] It is worth mentioning that please refer to Figure 1 The connection structure 303 is a connection plate, which is extended along the width direction of the film-making table 1. Further, two connection structures 303 are provided, and the two connection structures 303 are spaced apart along the length direction of the film-making table 1 to connect the dust cover 301 and the wind knife 302 on both sides.
[0045] It should be noted that, in the present embodiment, the dust hood 301 and the wind knife 302 both move synchronously with the cutting structure 202, and therefore, the volume of the dust hood 301 and the number of wind knives 302 are reduced accordingly. The above-mentioned "at least part of the dust removal mechanism 3 and the mobile cutting mechanism 2 can be moved synchronously" means: the dust hood 301 is fixed and the wind knife 302 moves synchronously with the cutting structure 202. Specifically, the dust hood 301 is extended along the length direction of the production table 1 (one dust hood 301 corresponds to the entire length direction of the production table 1 or several dust hoods 301 are arranged in sequence along the length direction of the production table 1), thereby covering the entire cutting path, and the number of wind knives 302 is reduced, so that the wind knife 302 can blow dust at the corresponding cutting position; or, the wind knife 302 is fixed and the dust hood 301 moves synchronously with the cutting structure 202. Specifically, there are multiple wind knives 302, and the multiple wind knives 302 are arranged in sequence along the length direction of the production table 1, thereby covering the entire cutting path, and the volume of the dust hood 301 is reduced, so that the dust hood 301 can dust at the corresponding cutting position.
[0046] In one embodiment, Figure 2As shown, the production table 1 is provided with an adsorption hole 101, which is suitable for connecting to a negative pressure generating structure. During the cutting process of the electrode strip, the negative pressure generating structure generates negative pressure in the adsorption hole 101, thereby adsorbing and fixing the electrode strip; when the cut electrode single piece needs to be unloaded, the negative pressure generating structure stops providing negative pressure for the adsorption hole 101, so that the production table 1 breaks the vacuum, which is convenient for unloading the electrode single piece.
[0047] In one embodiment, the cutting structure 202 includes a laser cutter or a cutter, that is, the laser cutter or the cutter is used to cut and slice the pole piece strip.
[0048] It is worth noting that the first drive structure 201 and the second drive structure 4 can be a linear motor module (high-speed drive), or a motor and lead screw module (medium and low-speed drive).
[0049] When using the film-making device of this embodiment, first, the electrode material strip is loaded onto the film-making table 1, and the electrode material strip is adsorbed and fixed through the adsorption holes 101 on the film-making table 1; then, the cutting structure 202, the dust hood 301 and the wind knife 302 are synchronously driven by the first driving structure 201, or, the cutting structure 202 is driven to move by the first driving structure 201, and the dust hood 301 and the wind knife 302 are driven to move synchronously with the cutting structure 202 by the second driving structure 4; during the movement of the cutting structure 202, the electrode material strip is cut and filmed, and the dust generated by the cutting is blown into the dust hood 301 by the positive pressure of the wind knife 302 and sucked into the dust hood 301 by the negative pressure of the dust hood 301, and enters the dust collector or the centralized dust removal system through the dust removal pipeline for collection and treatment.
[0050] According to an embodiment of the present utility model, on the other hand, a lamination device is provided, comprising the above-mentioned lamination device.
[0051] According to an embodiment of the present utility model, on another aspect, a battery production line is provided, comprising the above-mentioned lamination equipment.
[0052] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
