Description

Technical Field

[0001] The utility model belongs to the technical field of battery pole piece production, and in particular relates to a universal scraper fixing fixture for pole piece coating equipment and the pole piece coating equipment. Background Art

[0002] With the development of secondary battery technology, people have put forward higher requirements for battery capacity, volume and safety. How to improve the precision and controllability of electrode production is the key issue to achieve the above requirements. Coating, as one of the key steps in electrode production, directly affects the electrode coating efficiency and quality.

[0003] Existing laboratory coating machines usually need to be used with a set of scrapers. If a scraper that is not a set with the coating machine is used, the friction and resistance of the scraper cannot be maintained uniform and stable during the coating process due to the different sizes of the scrapers and the inability to cooperate well with the coating machine. It is easy to deviate, which significantly affects the coating efficiency and electrode quality. In addition, the deviation of the scraper will also cause abnormal wear of the coating equipment. On the one hand, the scraper may be more likely to deviate due to the influence of wear marks. On the other hand, the direction of the scraper deviation is not controllable, thus forming a large number of messy wear marks, which can easily directly scratch the electrode.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to solve one of the problems in the above-mentioned prior art, and to provide a universal scraper fixing fixture for electrode coating equipment. The fixing fixture can fix scrapers of different sizes and cooperate with the guide structure on the electrode coating equipment. Under the guidance of the guide structure, the stable coating is ensured, so that scrapers of different sizes and specifications can be smoothly coated on the electrode coating equipment.

[0006] On the other hand, the utility model also provides a pole piece coating device.

[0007] In order to achieve the above-mentioned purpose, the first aspect of the present invention provides a universal scraper fixing fixture for a pole piece coating device, wherein the pole piece coating device has a guiding structure for guiding the scraper to move along the coating direction, and the scraper fixing fixture includes:

[0008] The fixture body includes two guide parts set at intervals and a connecting part connecting the two guide parts. A scraper fixing area is formed between the two guide parts, which is used to drive the scraper to move along the coating direction through the cooperation between the guide parts and the guide structure.

[0009] The fixing component is connected to the clamp body and is movably arranged in the scraper fixing area for fixing the scraper.

[0010] In the above scheme, the scraper fixing fixture can cooperate with the guide structure on the electrode coating equipment and fix the scraper through the fixing component, thereby realizing the synchronous movement of the scraper and the fixing fixture during the coating process. Since the scraper fixing fixture is guided by the guide structure and can move along the coating direction, it effectively avoids the problem of mismatch between the scraper and the electrode coating equipment and the offset during the coating process, and at the same time reduces the wear between the scraper and the coating working surface to a certain extent.

[0011] Furthermore, a mirror plane is provided between the two guide portions, and the fixing component is movably arranged along a direction perpendicular to the mirror plane.

[0012] In the above scheme, the fixing component fixes the scraper in a direction perpendicular to the mirror plane, which can better fix the scraper and make it easier to disassemble and install the scraper, thereby improving the user experience; if the scraper is fixed in a direction parallel to the mirror plane, in order to ensure the stability of the scraper, multiple sets of fixing components need to be arranged in parallel, and if the fixing component is too long, it may affect the smooth progress of coating, and if it is too short, the scraper may not be sufficiently fixed, affecting the coating effect.

[0013] Furthermore, the fixing assembly includes:

[0014] a movable unit connected to the fixture body, at least a portion of which is movable relative to the fixture body in a direction perpendicular to the mirror plane;

[0015] The clamping unit is connected to the movable unit and is used to fix the scraper.

[0016] Furthermore, a threaded hole is provided on the guide portion, and the movable unit is provided as a threaded column which passes through the threaded hole and penetrates the guide portion, and is movably connected to the guide portion through the threaded hole;

[0017] The clamping unit is fixed to one end of the threaded column facing the scraper fixing area.

[0018] In the above solution, the distance between the clamping unit and the guide portion is changed by rotating the movable unit, thereby achieving fixation of the scraper, which is convenient for technicians to operate and can adjust the clamping tightness of the scraper according to actual usage.

[0019] Alternatively, as an alternative to the above solution, a through hole is provided on the guide portion, the movable unit passes through the guide portion through the through hole, and the clamping unit is fixed to one end of the threaded column facing the scraper fixing area;

[0020] The movable unit also includes a spring sleeved on the outside, with both ends of the spring respectively abutting against the guide portion and the clamping unit, and fixing the scraper in the scraper fixing area by squeezing the scraper through elastic force.

[0021] Furthermore, a limiting protrusion is provided on the movable unit, and the guiding portion is located between the limiting protrusion and the clamping unit.

[0022] In the above scheme, the spring can be compressed to place the scraper in the scraper fixing area only by pulling the movable unit from the side of the guide part away from the clamping area. After releasing the movable unit, the clamping unit automatically approaches the scraper and fixes the scraper under the action of the spring, making the operation more convenient. A limiting protrusion is provided on the movable unit, which can prevent the movable unit from falling out of the through hole even when the scraper is not clamped.

[0023] In order to facilitate disassembly, the limiting protrusion can be set to be detachably connected to the movable unit. In this way, when disassembly is required, it is only necessary to separate the limiting protrusion and the movable unit first to achieve disassembly of the fixed component.

[0024] Furthermore, the guide portion has a first end face in contact with the electrode coating device, and the connecting portion is connected to the two guide portions from a second end face of the guide portion connected to the first end face or a side close to the second end face;

[0025] The second end face is an end face adjacent to the first end face, and abuts against the connecting portion when the scraper is fixed in place.

[0026] In the above scheme, the connecting part connects the two guide parts on the one hand, thereby improving the stability of the scraper fixing fixture; on the other hand, it can also limit the scraper when fixing the scraper, further simplifying the scraper fixing operation. The technician does not need to actively align the scraper, but only needs to place the scraper against the connecting part to ensure that the scraper is fixed in place; for this reason, the connecting part is preferably arranged perpendicular to the mirror plane between the two guide parts.

[0027] Furthermore, the scraper fixing area has two fixing components that can move toward each other.

[0028] In the above solution, the two fixing components that can move toward each other can cooperate to fix the scraper from both sides of the scraper, and the fixed position of the scraper can be adjusted by adjusting the fixing components on both sides. Compared with the situation where the fixing component is set on only one side, the use flexibility is higher.

[0029] The second aspect of the present invention provides a pole piece coating device, which adopts the universal scraper fixing fixture of the above-mentioned solution, and has guide grooves parallel to each other on both sides of the coating panel of the pole piece coating device for guiding the scraper to move along the coating direction;

[0030] The two guide portions are parallel to each other, and the first end surface extends into the guide groove and abuts against the bottom of the guide groove.

[0031] Furthermore, the guide portion is further provided with a rotatable roller at least partially protruding from the first end surface, and the guide portion abuts against the bottom surface of the guide groove through the roller; or,

[0032] The guide groove is also provided with a rotatable roller that at least partially protrudes from the bottom surface, and the first end surface abuts the roller in the guide groove. In the above solution, the first end surface of the guide portion abuts the bottom of the guide groove, allowing the scraper fixing fixture to generate relative displacement along the direction of the guide groove during the coating process without falling out during movement. By providing the roller on the first end surface, the sliding displacement between the first end surface and the bottom of the guide groove during the coating process is converted into rolling displacement between the roller and the bottom of the guide groove, reducing the friction between the two. On the one hand, this ensures smooth coating, and on the other hand, it reduces or even avoids mutual wear between the first end surface and the bottom of the guide groove.

[0033] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art.

[0034] 1. The scraper fixing fixture can cooperate with the guide structure on the electrode coating equipment, and then drive the scraper to move along the direction guided by the guide structure during coating, avoiding the deviation of the scraper and affecting the quality of the electrode, and reducing the wear between the scraper and the coating working surface; it realizes the use of scrapers of different sizes and specifications with the same electrode coating equipment.

[0035] 2. When the scraper is fixed in place, the fixed component and the connecting part are used to limit the position, which prevents the scraper from falling off and moving during the coating process and improves the coating stability. The scraper can be fixed by the fixed component and the guide part / connecting part, or by the fixed components arranged in pairs, so that the appropriate scraper fixing method can be selected according to actual needs.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0047] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0048] In the description of the present invention, unless otherwise specified, the term "A and / or B" is generally understood, and its meaning includes three situations: only A, only B, and the presence of A and B at the same time.

[0049] In the description of the present invention, unless otherwise specified, the term "scraper" refers to a fixed scraper whose coating thickness cannot be adjusted.

[0050] In the description of this utility model, unless otherwise clearly specified and limited, "electrode coating equipment" refers to a small coating machine used for laboratory electrode coating. The small coating machine has a push rod movably arranged along the coating working surface. During coating, the push rod pushes the scraper to move to achieve coating.

[0051] The utility model provides a universal scraper fixing fixture for electrode coating equipment, wherein the electrode coating equipment has a guide structure for guiding the scraper to move along the coating direction, and the scraper fixing fixture includes a fixture body, the fixture body has two guide parts arranged at intervals and a connecting part connecting the two guide parts. During coating, the guide part cooperates with the guide structure so that the scraper fixing fixture can move along the coating direction under the guidance of the guide structure.

[0052] A scraper fixing area for fixing the scraper is formed between the two guide parts, and a fixing component is provided in the scraper fixing area, which is connected to the fixture body and is movably arranged in the scraper fixing area. When fixing the scraper, the scraper is first placed in the scraper fixing area, and then the fixing component is controlled to be close to and squeeze the scraper to fix the scraper in the scraper fixing area; the squeezing of the scraper can be achieved only by the fixing components arranged in pairs, or it can also be achieved by the cooperation of the fixing components and the relative guide parts; after the scraper is fixed, it moves synchronously along the coating direction under the drive of the scraper fixing fixture to complete the coating, thereby avoiding the mismatch between the scraper and the electrode coating equipment and the offset during the coating process, which affects the quality of the electrode; and the fixation of the scraper by the scraper fixing fixture reduces the mutual wear between the scraper and the electrode coating equipment to a certain extent; and compared with the adjustable scraper with adjustable gap, the present embodiment can replace the fixed scraper with different gaps as needed, which is simpler to operate and has higher accuracy and reliability.

[0053] Next, combine Figures 1 to 8 The present invention is further described with reference to specific embodiments.

[0054] Example 1

[0055] As an embodiment of the present invention, this embodiment provides a universal scraper fixing fixture for a pole piece coating device, comprising a fixture body 1 and a fixing assembly 2 movably arranged on the fixture body 1 .

[0056] In this embodiment, if Figure 1As shown, the clamp body 1 includes two guide parts 101 arranged at intervals, and a connecting part 102 connecting the two guide parts 101. The two guide parts 101 are parallel to each other, and have a first end face 1011 facing the coater during the coating process, and a second end face 1012 connected to the first end face 1011. The connecting part 102 is connected to the two guide parts 101 from the second end face 1012. At this time, the connecting part 102 not only connects and fixes the two guide parts 101, but is also used to limit the scraper 3. When fixing the scraper 3, the technician does not need to manually straighten the scraper 3 or adjust the posture of the scraper 3. The scraper 3 can be directly pressed against the connecting part 102, which further simplifies the operating steps of fixing the scraper 3 and improves the user experience of the technician.

[0057] Furthermore, there are two fixing components 2 arranged in pairs in the scraper fixing area between the two guide parts 101. The two fixing components 2 are positioned opposite to each other, are respectively connected to the two guide parts 101, and are movably arranged relative to the guide parts 101 in a direction perpendicular to the guide parts 101. When fixing the scraper 3, the two fixing components 2 approach each other and clamp the scraper 3 from both sides along the direction perpendicular to the guide parts 101.

[0058] In this embodiment, both guide parts 101 have through holes, and the opening direction of the through holes is perpendicular to the plane where the guide parts 101 are located. The fixing component 2 is movably connected to the guide parts 101 through the through holes. Specifically, in order to achieve the movable connection with the guide parts 101, the fixing component 2 includes a movable unit 201, a clamping unit 202 and a spring 204. The clamping unit 202 is arranged at the end of the movable unit 201. Driven by the movable unit 201, the clamping unit 202 contacts and squeezes the scraper 3, and the scraper 3 is fixed by friction. The movable unit 201 passes through the through hole, and the spring 204 is sleeved on the movable unit 201. The outer side of the unit 201 is located between the guide part 101 and the clamping unit 202, and is used to provide the clamping unit 202 with a force to squeeze the scraper 3; when clamping the scraper 3, the technician first pulls the movable unit 201 from both sides of the clamp body 1 so that the two clamping units 202 move away from each other, so that the scraper 3 can be accommodated between the two clamping units 202, and then places the scraper 3 between the two clamping units 202, releases the movable unit 201, and at this time the clamping units 202 approach each other under the action of the restoring force of the spring 204, clamping the scraper 3 from both sides, thereby fixing the scraper 3.

[0059] In other embodiments, the two guide portions 101 may also be arranged to be mirror-symmetrical, the symmetry plane bisects the connecting portion 102, and the two bisected parts are also mirror-symmetrical about the symmetry plane. At this time, the through holes on the guide portions 101 are also mirror-symmetrical about the symmetry plane, and the opening direction is perpendicular to the symmetry plane. In addition, in other embodiments, the fixing component 2 may also clamp the scraper 3 along the plane where the symmetry plane is located. For example, with the moving direction of the scraper 3 during the coating process as the first direction, the fixing component 2 clamps the scraper 3 from both sides along the first direction.

[0060] Example 2

[0061] As another embodiment of the present invention, this embodiment differs from the first embodiment in that only one fixing assembly 2 is provided.

[0062] In this embodiment, if Figure 2 As shown, when the scraper 3 needs to be fixed, the technician pulls out the part of the movable unit 201 located on the outside of the clamp body 1, so that the clamping unit 202 moves in the withdrawal direction, and then places the scraper 3 on the scraper 3 fixing area, and then releases the movable unit 201. At this time, the clamping unit 202 approaches the scraper 3 under the action of the rebound force of the spring 204 and applies a force to the scraper 3, so that the scraper 3 moves in the direction of the guide part 101 on the other side and abuts against the guide part 101, and finally the scraper 3 is fixed by the cooperation of the guide part 101 and the clamping unit 202.

[0063] In other embodiments, the guide portion 101 on the other side may also be provided with a protrusion protruding inward, which abuts against the scraper 3 through the protrusion, thereby reducing the stroke of the movable unit 201 when clamping the scraper 3, shortening the length of the movable unit 201, and avoiding the problem that the movable unit 201 is too long and difficult to operate.

[0064] Example 3

[0065] As another embodiment of the present invention, this embodiment further makes the following improvements based on the first embodiment: In this embodiment, the fixing assembly 2 further includes a limiting protrusion 2011, which prevents the fixing assembly 2 from being separated from the through hole.

[0066] Since one end of the movable unit 201 is provided with a clamping unit 202, when the scraper 3 is not fixed, the movable unit 201 may be separated from the through hole under the rebound force of the spring 204, which may easily lead to the loss of the fixing component 2 in the long run. Figure 3As shown, an additional limiting protrusion 2011 is provided on the movable unit 201, and the limiting protrusion 2011 is spaced apart from the clamping unit 202 so that the guide portion 101 is located between the clamping unit 202 and the limiting protrusion 2011. Under the action of the rebound force of the spring 204, the limiting protrusion 2011 abuts against the guide portion 101, effectively preventing the movable unit 201 from falling out.

[0067] Furthermore, considering the maintenance and replacement requirements of each part in the fixed component 2, in this embodiment, the limiting protrusion 2011 is set to be detachable from the movable unit 201, and then when the fixed component 2 needs to be replaced and maintained, the limiting protrusion 2011 on the fixed component 2 can be removed; in this embodiment, the limiting protrusion 2011 can be set to be connected to the movable unit 201 through the threaded holes on the circumference of the movable unit 201.

[0068] In other embodiments, the limiting protrusion 2011 can also be integrally provided with the movable unit 201, and the clamping unit 202 can be provided to be detachably connected to the fixed component 2, or the movable unit 201 can be provided in two detachable sections; the detachable manner can be achieved through a threaded connection, or through a mortise and tenon connection, a pin hole connection, or other conventional methods in the field, which will not be elaborated here.

[0069] Example 4

[0070] As another embodiment of the present invention, this embodiment provides a universal scraper fixing fixture for electrode coating equipment, which differs from the first embodiment in that the structure of the fixing component 2 is different.

[0071] In this embodiment, if Figure 5 As shown, the through holes symmetrically arranged on the two guide parts 101 are threaded holes, and the movable unit 201 is a threaded column with external threads. The external threads of the movable unit 201 cooperate with the internal threads of the threaded holes to achieve a movable connection with the guide parts 101. The scraper fixing fixture in the scraper clamping state is as shown in FIG. Figure 4 As shown; the clamping unit 202 is fixed at one end of the movable unit 201 facing the scraper fixing area. When the scraper 3 needs to be clamped, the technician first rotates the movable unit 201 so that the clamping units 202 on the two guide parts 101 are away from each other, and then places the scraper 3 in the clamping area, and rotates the movable unit 201 in the opposite direction so that the two clamping units 202 are close to each other and squeeze the scraper 3, and the scraper 3 is fixed by friction.

[0072] In order to facilitate the operation of technicians, a rotating handle 203 is provided at the end of the movable unit 201 away from the scraper clamping area. In this embodiment, the handle 203 is set to a long handle type and is detachably connected to the movable unit 201. The detachable connection method can be a mortise and tenon connection or a pin hole connection; in other embodiments, the handle 203 can also be set to a gear type or other common handle 203 forms, which will not be repeated here.

[0073] Example 5

[0074] As another embodiment of the present invention, this embodiment provides a universal scraper fixing fixture for electrode coating equipment, which differs from the third embodiment in that the structure of the fixture body 1 is different.

[0075] In this embodiment, if Figure 6 As shown, the guide portion 101 also has a third end face 1013 opposite to the first end face 1011, and the connecting portion 102 is connected to the two guide portions 101 from the third end face 1013 and is perpendicular to the two guide portions 101. In this solution, the connecting portion 102 is no longer used to limit the scraper 3, but serves as a gripping structure of the scraper fixing fixture. The technician can grip the scraper fixing fixture through the connecting portion 102, which improves the convenience of using the scraper fixing fixture; in order to facilitate the technician to grip, the connecting portion 102 is set to be cylindrical as a whole, and the fixing component 2 is set close to the first end face 1011, which improves the convenience of the user to grip the connecting portion 102 and avoids being scratched by the scraper 3 during the gripping process.

[0076] The present utility model also provides a pole piece coating device, which adopts the universal scraper fixing fixture described in the above embodiment, and is specifically as follows.

[0077] Example 6

[0078] As an embodiment of the present invention, this embodiment provides a pole piece coating device, which adopts the universal scraper fixing fixture as described in the first embodiment.

[0079] Specifically, the electrode coating equipment includes a coating working surface 4, and a push rod 5 with a gap between it and the coating working surface 4, which can be translated along a plane parallel to the coating working surface 4. When the coater is working, the current collector is spread on the coating working surface 4, and liquid active material is poured on the surface. The push rod 5 is placed on the coating working surface 4, and the scraper 3 is driven to move by pushing the scraper fixing fixture. During the movement of the scraper 3, the liquid active material is spread and flattened on the upper layer of the current collector to obtain a pole piece.

[0080] In this embodiment, if Figure 7 or Figure 8As shown, there are guide grooves 401 parallel to each other on both sides of the coating working surface 4, and the guide grooves 401 are used to guide the scraper 3 to move along the coating direction. The interval between the two guide parts 101 in the scraper fixing fixture is the same as the interval between the guide grooves 401, so that when the scraper fixing fixture is placed on the coating working surface 4, the first end face 1011 abuts against the bottom of the guide groove 401, and then under the push of the push rod 5, the scraper 3 fixed in the scraper fixing fixture can move stably under the guidance of the guide groove 401, even if the scraper 3 and the electrode coating equipment do not match, coating can be carried out smoothly.

[0081] It should be understood by those skilled in the art that the solution described in this embodiment may also adopt the general scraper fixing fixture described in Examples 2 to 5, and the solution obtained by combining this embodiment with Examples 2 to 5 also falls within the scope of protection of the present utility model.

[0082] In particular, when combined with Example 5, the setting method of the scraper fixing clamp is different from that of other embodiments. In other embodiments, the connecting portion 102 is located on the side of the scraper fixing clamp close to the push rod 5, and the push rod 5 can push the scraper fixing clamp to move by contacting the connecting portion 102 or by contacting the second end face 1012; when combined with Example 5, the connecting portion 102 is located at the top of the scraper fixing clamp, which is convenient for technicians to directly grab it. At this time, the push rod 5 can only push the scraper fixing clamp to move by contacting the second end face 1012.

[0083] Example 7

[0084] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the sixth embodiment.

[0085] In this embodiment, a roller is further provided at the bottom of the guide groove 401. The surface of the roller protrudes from the bottom of the guide groove 401 and is rotatable relative to the bottom of the guide groove 401. The rotation axis is parallel to the bottom of the guide groove 401. When the scraper fixing fixture is placed on the electrode coating device, the first end face 1011 extends into the guide groove 401 and abuts against the surface of the roller. When the push rod 5 pushes the scraper fixing fixture, the roller converts the original sliding displacement between the first end face 1011 and the bottom surface of the guide groove 401 into a rolling displacement, thereby reducing the movement resistance and further improving the stability of the electrode preparation.

[0086] In other embodiments, the roller can also be set on the first end surface 1011 of the guide part 101, so that the roller surface protrudes from the first end surface 1011. The guide part 101 abuts against the bottom of the guide groove 401 through the roller, and can also convert the sliding displacement into rolling displacement, thereby reducing the movement resistance between the two.

[0087] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
