Abstract

The application provides a film material processing device, a method and a dry coating machine. The film material processing device comprises a preheating assembly and a roller pressing assembly. The preheating assembly comprises a heat source for heating the film material. The preheating assembly and the roller pressing assembly are arranged in sequence on a conveying route of the film material. The roller pressing assembly comprises two pressing rollers arranged at intervals in a first direction, and a roller pressing channel for pressing the film material is formed between the pressing rollers. The preheating assembly preheats the film material, so that the film material can enter the roller pressing channel at a certain initial temperature. On the one hand, this allows the pressing rollers to heat the film material less or even not to heat the film material during the pressing process, thereby allowing the film material to pass through the pressing rollers at a higher speed and improving the production efficiency of the film material pressing. On the other hand, this also reduces the heat waste of the pressing rollers and reduces the operating energy consumption of the film material processing device.

Description

Technical Field

[0001] This application relates to the field of dry coating, and in particular to a film material processing device, method and dry coating machine. Background Technology

[0002] The dry coating process involves dropping the mixture, which has undergone fiberization treatment, through a hopper onto a roller press to form an electrode film with self-supporting properties. The electrode film is then laminated onto a foil and transported together to another roller press for further pressing to achieve lamination.

[0003] Whether it's the rolling process of the blend after the original fiberization treatment, or the rolling process of electrode films and foils, the rolling effect can be improved by increasing the temperature of the film to be rolled. Currently, heated rollers are often used to heat the film to be rolled. This method requires inputting high-temperature hot oil into the rollers. During the rolling process, heat is wasted on the surface of the rollers that are not in contact with the film. Components directly connected to the rollers either need to be made of high-temperature resistant materials or require heat dissipation structures.

[0004] Furthermore, the pressure roller and the film material are in near-line contact, resulting in a small contact area. The film material needs to pass through the pressure roller at a low speed to achieve sufficient heating, which reduces the production efficiency of the film material roller pressing. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a film material processing equipment, method, and dry coating machine, wherein the film material processing equipment can improve the production efficiency of film material rolling.

[0007] The film material processing equipment provided in this application has at least the following technical effects: the preheating component preheats the film material, enabling the film material to enter the roller pressing channel at a certain initial temperature. On the one hand, this avoids the problem of low film material production efficiency caused by reducing the speed of the film material passing through the rollers to ensure sufficient heating of the film material by the rollers. This increases the speed of the film material passing through the rollers and improves the production efficiency of film material roller pressing. On the other hand, this also reduces the heat waste of the rollers and reduces the operating energy consumption of the film material processing equipment.

[0050] Reference Figure 1 The film material processing equipment provided in this application includes a preheating assembly 100 and a rolling assembly 200. The preheating assembly 100 includes a heat source 110 for heating the film material 900. The preheating assembly 100 and the rolling assembly 200 are arranged sequentially on the conveying route of the film material 900. The rolling assembly 200 includes two pressure rollers 210 arranged at intervals in a first direction, and a rolling channel for rolling the film material 900 is formed between the pressure rollers 210.

[0051] Understandably, in Figure 1 In similar embodiments, the first direction refers to the up-down direction and the Z-direction; the second direction refers to the left-right direction and the Y-direction; and the third direction refers to the front-back direction and the X-direction. In other embodiments, the first, second, and third directions may use different designations. Figure 1 In one embodiment, a section of the conveying route is in the third direction, and the preheating assembly 100 and the rolling assembly 200 are arranged on this section of the conveying route, combined with Figure 4 The axis of the pressure roller 210 is along the second direction, which is also the width direction of the film material 900.

[0052] Combined with reference Figure 10 This application also provides a membrane material treatment method, which uses membrane material treatment equipment and includes the following steps:

[0053] Step S100: The film material 900 is conveyed along the conveying route so that the film material 900 passes through the preheating component 100 and the rolling component 200 in sequence;

[0054] Step S200: Preheating component 100 preheats film material 900;

[0055] Step S300: Roller pressing assembly 200 rolls film material 900.

[0056] According to the film material processing equipment provided in this application, the preheating component 100 preheats the film material 900, enabling the film material 900 to enter the roller pressing channel at a certain initial temperature. On the one hand, this allows the pressure roller 210 to heat the film material 900 less or not at all during the roller pressing process, thereby allowing the film material 900 to pass through the pressure roller at a higher speed, improving the production efficiency of film material roller pressing. On the other hand, this also reduces the heat waste of the pressure roller 210 and reduces the operating energy consumption of the film material processing equipment.

[0057] The membrane material processing method uses the membrane material processing equipment provided in this application. Therefore, the membrane material processing method has the beneficial effects brought about by the membrane material processing equipment of this application.

[0058] When the film material processing equipment and methods are applied to the dry coating process of lithium battery electrodes, the film material 900 can be either a mixture that has undergone original fiberization treatment and is to be rolled, or a foil material covered with an electrode film and to be rolled and laminated.

[0059] Reference Figure 1 In some embodiments, the preheating assembly 100 includes a preheating outlet, the size of which in a first direction is smaller than the center-to-center distance between the two pressure rollers 210. The phrase "the size of the preheating outlet in the first direction is smaller than the center-to-center distance between the two pressure rollers 210" means that the preheating outlet and the roller pressing channel are on the conveying path (i.e., Figure 1 The distance between the two pressure rollers 210 (in the third direction) can be less than the radius of the pressure roller, that is, the preheating outlet can extend between the two pressure rollers 210. In the first direction, the projection of the pressure roller 210 overlaps with the preheating outlet.

[0060] Understandably, when the film material 900 leaves the preheating outlet, it radiates heat to the environment, causing its temperature to drop. This increases heat waste in the film material processing equipment and also increases the initial temperature fluctuation of the film material when entering the rolling channel, thus reducing the quality stability of the film material rolling process. By using a preheating outlet with a smaller size in the first direction, the preheating outlet can be placed closer to the rolling channel, thereby reducing heat waste and temperature fluctuation.

[0061] Specifically, the preheating component 100 can be implemented in various different ways to ensure that the size of the preheating outlet meets the requirements. For example, in some embodiments, refer to Figure 1, Figure 4 and Figure 6 The preheating assembly 100 includes two cover plates 120 extending along the conveying path of the film material 900. The two cover plates 120 are spaced apart in a first direction, forming a preheating channel open at both ends through which the film material 900 passes. The maximum distance between the two cover plates 120 in the first direction is less than the center-to-center distance between the two pressure rollers 210. This "maximum distance" includes the thickness of the cover plate 120. The ends of the cover plates 120 form preheating outlets, the size of which in the first direction is necessarily less than or equal to the maximum distance, thus ensuring that the size of the preheating outlet meets the requirements. Figure 6 As shown, two cover plates 120 each have grooves formed on their surfaces. The grooves of the two cover plates 120 are arranged facing each other, and the two grooves combine to form a preheating channel. The preheating channel is closed in the second direction, thereby reducing heat waste during preheating. Of course, only one cover plate 120 can have a groove, with the groove facing the other cover plate 120 in the first direction. The other cover plate 120 covers the groove to form a preheating outlet.

[0062] In some embodiments, the heat source 110 includes heating elements arranged within a preheating channel. Two sets of heating elements are respectively arranged on two sets of cover plates 120. The heating elements are relatively thin, allowing the preheating assembly 100 to be further reduced in size in the first direction. This allows the preheating outlet to be closer to the rolling channel, reducing heat waste and temperature fluctuations. The two sets of heating elements heat the film material 900 from both sides, resulting in uniform heating of the film material 900. (Refer to...) Figure 2 The heating elements are evenly laid on the cover plate 120 to form a heating area. The heating area extends in the third direction, thereby extending the preheating time of the membrane material 900. The size of the heating area in the second direction is larger than the width of the membrane material 900 to avoid the edges of the membrane material 900 not being heated properly.

[0063] Of course, in other embodiments, the preheating component 100 can also be implemented in a tapered or segmented manner, or a combination of multiple implementation methods can be used, which can also ensure that the size of the preheating outlet meets the requirements. In the tapered manner, the size of the preheating component 100 gradually decreases along the conveying route in the first direction; in the segmented manner, the preheating outlet is located at the outlet section of the preheating component 100, and the maximum distance of the outlet section in the first direction is less than the center distance between the two pressure rollers 210. Other sections of the preheating component 100 can adopt other structural designs based on specific requirements. In other locations of the preheating component 100, if space permits, hot air or other methods can also be used to preheat the film material 900.

[0064] The preheating component 100 can control the initial temperature of the membrane material 900 by controlling the heating power of the heat source 110. To improve the accuracy of initial temperature control, in some embodiments, the membrane material processing equipment includes a temperature measuring component 300, with its detection end facing the conveying route. The temperature measuring component 300 measures the temperature of the membrane material 900, and the membrane material processing equipment adjusts the heat source 110 accordingly. The temperature measuring component 300 may include specific temperature measuring devices such as a temperature sensor or a thermal imager.

[0065] Along the first direction, a cover plate 120 on one side of the membrane material 900 is distributed between the membrane material 900 and the temperature measuring component 300.

[0066] Specifically, refer to Figure 1 and Figure 2 In some embodiments, the preheating assembly 100 is fixedly installed, and the temperature measuring assembly 300 is located on one side of the conveying route in the second direction, with the detection end of the temperature measuring assembly 300 facing the conveying route adjacent to the roller pressing channel. In this case, the temperature measuring assembly 300 can detect the temperature of the film material 900 about to enter the roller pressing channel, thereby enabling precise feedback adjustment. Arranging the temperature measuring assembly 300 on the side allows it to be as close as possible to the position to be measured, while avoiding interference with the preheating assembly 100 and the roller pressing assembly 200. Meanwhile, referring to... Figure 2 The film material processing equipment can also arrange temperature measuring components 300 on both sides of the conveying route to reduce errors by integrating the data measured by multiple temperature measuring components 300.

[0067] However, when the pressure roller 210 is hot, the heat radiated outward by the pressure roller 210 may interfere with the temperature measuring component 300, resulting in increased temperature detection error and reduced accuracy of feedback adjustment.

[0068] Therefore, referring to Figure 3 In other embodiments, the preheating component 100 can move along a third direction to switch between a preheating station and a temperature measuring station. The temperature measuring station is located on the side of the preheating station away from the roller pressing component 200. The temperature measuring component 300 is arranged at the temperature measuring station. When the preheating component 100 is at the temperature measuring station, the detection end of the temperature measuring component 300 faces the conveying path located at the output end of the temperature measuring station. When the film material 900 is conveyed along the conveying path, the temperature measuring component 300 measures the temperature of the film material 900. By moving the temperature measuring component 300 away from the roller pressing component 200, the influence of the heat from the pressure roller 210 on the temperature measurement can be reduced, improving the accuracy of feedback adjustment.

[0069] It is understandable that "the output end of the temperature measurement station" refers to the side of the temperature measurement station near the roller pressing assembly 200, and the conveying route can refer to either a sampling point at the output end or a sampling area.

[0070] In such an embodiment, the step of preheating the film material 900 by the preheating component 100 during the film material processing method includes:

[0071] Step S210: Turn on heat source 110;

[0072] Step S220: The preheating component 100 is moved to the temperature measurement station;

[0073] Step S230: Temperature measuring component 300 detects the temperature of the membrane material 900 leaving the preheating outlet;

[0074] Step S240: In response to the temperature detected by the temperature measuring component 300, adjust the output power of the preheating component 100 until the temperature detected by the temperature measuring component 300 reaches the set target;

[0075] Step S250: The preheating component 100 is moved to the preheating station.

[0076] In other words, before the formal preheating and rolling, the preheating component 100 first conducts a preheating experiment at the temperature measurement station, allowing the film material 900 to pass through the preheating component 100. The preheating component 100 preheats the film material 900, and uses the temperature of the film material 900 measured in the experiment to estimate the temperature of the film material 900 when it reaches the rolling channel when the preheating component 100 is in the preheating station. After the heating effect of the preheating component 100 reaches the set target, it then goes to the preheating station, allowing the film material 900 to enter the rolling channel for rolling after being preheated by the preheating component 100.

[0077] In some embodiments, the film material handling equipment includes a first guide rail slider mechanism 520, the first guide rail of which extends in a third direction, and the preheating assembly 100 is mounted via the first guide rail slider mechanism 520, thereby enabling smooth movement. Specifically, in Figure 3 and Figure 4 In one embodiment, the film material processing equipment includes a frame, the frame includes a first mounting base 511, a first guide rail is mounted on a cover plate 120, and a first slider of the first guide rail slider mechanism 520 is mounted on the first mounting base 511 of the film material processing equipment.

[0078] To improve the accuracy of the estimation, in some embodiments, when the preheating component 100 is located at the temperature measurement station, the distance between the detection end and the preheating outlet in a third-order direction is defined as L1, and the distance between the roller pressing channel and the preheating outlet in a third-order direction is defined as L2. The difference between L1 and L2 is less than or equal to a first preset value. "Detection end position" refers to the sampling position of the detection end on the conveying route during temperature measurement. When the sampling position is a single point, that point is the "detection end position." When the sampling position is a region, the points set within that region are the "detection end position," such as the center of the region, the highest temperature point, the lowest temperature point, etc. This allows the preheating experiment at the temperature measurement station to simulate the temperature drop of the film material 900 after leaving the preheating outlet, making the temperature detected by the temperature measurement component 300 closer to the actual temperature of the roller pressing channel. Normally, the first preset value is set to be less than or equal to 10 mm. Ideally, the first preset value is set to 0, that is, L1 equals L2, thereby obtaining better detection accuracy.

[0079] Reference Figure 3 In some embodiments, the detection end faces the conveying route along the first direction. In this case, the distance between the detection end and the preheating outlet in the third direction can be used as L2, eliminating the need to calculate the sampling position and making the membrane material processing equipment more convenient to use.

[0080] In some embodiments, the film material processing equipment includes a support assembly 400 located in a third direction between a temperature measuring station and a roller pressing channel. The support assembly 400 includes a support roller 410 extending in a second direction and capable of approaching or moving away from the conveying route in a first direction. In a corresponding film material processing method, when the preheating assembly 100 moves to the temperature measuring station (i.e., during or after step 220), the support roller 410 approaches the conveying route in the first direction to support the film material 900; when the preheating experiment is completed (i.e., during or before step 250), the support roller 410 moves away from the conveying route in the first direction to avoid the preheating assembly 100.

[0081] The support roller 410 moves toward the conveying path to support the film material 900, so as to prevent the film material 900 from wrinkling or sagging due to lack of support after the preheating component 100 moves away, which would cause the detection position at the detection end to change and thus increase the error of the detection result.

[0082] In some embodiments, the film material processing equipment includes a second guide rail slider mechanism 530, the second guide rail of which extends along a first direction, and the support assembly 400 is mounted via the second guide rail slider mechanism 530, thereby enabling smooth movement. Specifically, in Figure 4 and Figure 5In this embodiment, the second guide rail of the second guide rail slider mechanism 530 is mounted on the frame, the support assembly 400 includes a roller frame 420, the roller frame 420 is mounted on the second slider of the second guide rail slider mechanism 530, the two roller frames 420 are arranged at a distance in the second direction, and the support roller 410 is mounted between the two roller frames 420.

[0083] Further reference Figure 5 The film material processing equipment may also include a position detection element 516, which detects whether the support roller 410 has moved into place.

[0084] Back Figure 4 In some embodiments, the roll forming assembly 200 includes a rotary drive 220, which is drively connected to the pressure roller 210 and drives the pressure roller 210 to rotate for roll forming. (See also...) Figure 8 In some embodiments, the frame includes a second mounting base and a connecting plate 512. The pressure roller 210 is mounted between two second mounting bases, the connecting plate 512 is mounted on one of the second mounting bases, and a rotary drive 220 is mounted on the connecting plate 512. The rotary drive 220 is connected to the pressure roller 210 via a coupling 230. To balance the torque generated by the rotary drive 220, the second mounting base is also provided with a groove, and the connecting plate 512 is mounted in the groove.

[0085] In some embodiments, the second mounting base is further divided into a fixed base 513 and a sliding base 514, as shown in reference. Figure 9 The frame includes a third mounting base 515, a fixed base 513 is fixedly mounted on the third mounting base 515, and a sliding base 514 is mounted on the third mounting base 515 through a third guide rail slider mechanism 540. The third guide rail of the third guide rail slider mechanism 540 extends along the first direction, so that the two pressure rollers 210 can smoothly approach or move away from each other.

[0086] To ensure uniform quality of the film material 900 after roller pressing, it is necessary to control the pressure of the two pressure rollers 210 on the film material 900.

[0087] In some embodiments, the film processing equipment includes a barrier 551 disposed between two pressure rollers 210 to limit the minimum distance between the two pressure rollers 210, preventing the pressure rollers 210 from getting too close and causing the pressure to exceed the range. (Back) Figure 4In some embodiments, the barrier 551 includes a wedge block and a wedge seat, which are respectively mounted on two second mounting seats. The wedge block and the wedge seat have corresponding inclined surfaces. The film material processing equipment also includes a first drive 552, which is connected to the wedge block by a self-locking transmission method, such as threaded drive or screw drive. The first drive 552 pushes the wedge block to move in a third direction, thereby causing the wedge block to move closer to or further away from the wedge seat under the action of the inclined surface, thereby adjusting and limiting the minimum distance between the two second mounting seats.

[0088] In some embodiments, the film material processing equipment includes a pressure detection element 561 and a second drive element 562. The second drive element 562 is connected to a sliding seat 514 and is used to drive the sliding seat 514 to move along a first direction. The pressure detection element 561 is connected between the second drive element 562 and the sliding seat 514, and detects the reaction force generated by the sliding seat 514. See details... Figure 8 The pressure detection element 561 is a pressure sensor, which is mounted on the sliding seat 514. The second drive element 562 is a hydraulic cylinder, and the output shaft of the second drive element 562 abuts against the pressure detection element 561. When a part of the film material 900 is thinned or thickened, the reaction force will decrease or increase. The second drive element 562 can adjust the thrust on the sliding seat 514 according to the set scheme to compensate and keep the pressure within the preset range.

[0089] To compensate for errors, a certain degree of freedom of motion needs to be provided between the second driving component 562 and the sliding seat 514. Figure 8 In this embodiment, the film material processing equipment includes an adapter 517, which is mounted on a sliding seat 514. The adapter 517 has a T-slot extending in a second direction. The output shaft of the second drive member 562 is embedded in the T-slot, and the diameter of the output shaft is smaller than the width of the T-slot opening. This allows the second drive member 562 and the sliding seat 514 to maintain a certain degree of freedom of movement in the third, first, and second directions, and even if the output shaft is not coaxial with the third guide rail, it is not easy for the operation to jam.

[0090] The dry coating machine provided in this application includes the film material processing equipment provided in this application.

[0091] Dry coating machines include film material handling equipment; therefore, dry coating machines have the same benefits as film material handling equipment.

[0092] Film processing equipment can be used for mixing roll pressing and / or foil pressing in dry coating machines. Taking foil pressing as an example, refer to... Figure 9In some embodiments, the dry coating machine further includes an unwinding assembly, a thickness measuring assembly 620, and a winding assembly 630. The unwinding assembly, preheating assembly 100, rolling assembly 200, thickness measuring assembly 620, and winding assembly 630 are arranged sequentially along the conveying path of the film material 900.
