Description

Technical Field

[0001] The utility model belongs to the technical field of battery pole piece production, and specifically relates to a blade universal pole piece coating device. Background Art

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

[0003] Existing laboratory coating machines usually need to be used in combination with a complete set of blades. Although they can also cooperate with blades of different specifications produced by other manufacturers, they cannot achieve stable coating like a complete set of blades. During the coating process, the friction and resistance received by the blade cannot be maintained evenly and stably, and it is easy to shift, directly affecting the coating efficiency and the quality of pole pieces. In addition, the shift of the blade will also cause abnormal wear of the coating equipment, and the blade may be more prone to shift due to the influence of wear marks.

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

[0005] The technical problem to be solved by the present utility model is to solve one of the above-mentioned problems in the prior art, and provide a blade universal pole piece coating device. By setting a fixing structure to fix the blade and connecting the blade to the push rod, the blade always moves synchronously with the push rod, avoiding the occurrence of blade shift. Therefore, blades of different sizes and specifications can all be smoothly coated on the pole piece coating device.

[0006] To achieve the above object, the present utility model provides a blade universal pole piece coating device, including a fixing device provided on the push rod, and a blade fixing clamp cooperating with the fixing device;

[0007] The blade fixing clamp is detachably connected to the fixing device, and is used for clamping the blade and cooperating with the fixing device to connect the blade to the push rod.

[0008] In the above solution, after the blade fixing clamp clamps the blade and is connected to the fixing device, the fixed connection between the blade and the push rod is realized, so that the blade always moves synchronously with the push rod during the movement of the push rod. Even if the blade does not match the pole piece coating device, it will not shift during the coating process, improving the versatility of the pole piece coating device and enabling smooth coating with blades of different sizes and specifications.

[0009] Further, the push rod is provided with a track arranged along the length direction, the fixing device is detachably arranged in the track, and is slidably arranged relative to the push rod along the track.

[0010] During coating, the doctor blade may be set at different positions according to actual usage requirements. In the above solution, the fixing device is set to be slidable along the length direction of the push rod, and the position of the doctor blade under different coating requirements can be adjusted by adjusting the position of the fixing device on the push rod.

[0011] Furthermore, the fixing device includes

[0012] an adjusting component, detachably arranged in the track of the push rod and slidable relative to the push rod along the track;

[0013] a fixing component, connected to the adjusting component and protruding from the surface of the push rod. The fixing device is detachably connected to the doctor blade fixture through the fixing component.

[0014] Furthermore, the adjusting component further includes

[0015] a first locking unit, telescopically arranged relative to the adjusting component and used to adjust the friction between the track and the adjusting component.

[0016] In the above solution, in order to prevent the fixing device from displacing in the track during the coating process, a first locking unit is provided on the adjusting component. When the fixing device and the push rod are relatively stationary, the first locking unit extends and abuts against the inner wall of the track and squeezes the inner wall of the track, increasing the friction between the adjusting component and the track, thereby achieving their relative static state; when the position of the fixing device needs to be adjusted, the first locking unit retracts, and the friction between the adjusting component and the inner wall of the track decreases. At this time, the fixing device can slide relatively easily along the track.

[0017] Furthermore, the doctor blade fixture includes

[0018] a clamping component, used to fix the doctor blade;

[0019] a connecting component, connected to the clamping component and used to cooperate with the fixing device to connect the doctor blade fixture and the push rod.

[0020] Furthermore, the connecting component is a rigid connecting rod with a certain length, and the fixing component on the push rod is correspondingly provided with a through hole for the connecting rod to pass through;

[0021] The fixing component is provided with a second locking unit, and the second locking unit is telescopically arranged into the through hole from the inner wall of the through hole.

[0022] In the above solution, the connecting component is set as a rigid connecting rod with a certain length, and through holes for the connecting rod to penetrate are correspondingly arranged on the fixing component. The two are locked by a second locking unit similar to the first locking unit, that is, the relative fixation of the two is achieved by increasing the friction between the inner peripheral wall of the through hole and the connecting component, making the disassembly between the fixing device and the scraper fixing fixture easier and improving the use experience of technicians.

[0023] Furthermore, the clamping component includes a first clamping plate and a second clamping plate that are spaced apart on the side of the connecting rod. The two are opposite in position, and the distance between them matches the width of the scraper.

[0024] In the above solution, the distance between the first clamping plate and the second clamping plate matches the width of the scraper, realizing the limitation of the scraper in the moving direction of the scraper during coating, and restricting the displacement of the scraper in the direction perpendicular to the moving direction of the scraper through the friction between the first clamping plate, the second clamping plate and the scraper, thereby realizing the full clamping and fixation of the scraper.

[0025] Alternatively, as an alternative to the above solution, the first clamping plate is located at the end of the connecting rod, the second clamping plate is slidably arranged relative to the connecting rod along the length direction of the connecting rod, and the second clamping plate always has a tendency to move closer to the first clamping plate.

[0026] In the above solution, the second clamping plate is slidably arranged relative to the connecting rod, and there is always a tendency for the two to move closer to each other. While limiting the scraper in the moving direction of the scraper through the first clamping plate and the second clamping plate, forces are also applied to the scraper from opposite sides, more stably realizing the clamping of the scraper and further improving the clamping stability of the scraper.

[0027] Furthermore, the inside of the connecting component has a cavity, and a linkage unit that is slidable along the length direction of the connecting component is arranged in the cavity. One end of the linkage unit penetrates the side wall of the connecting component and is connected to the second clamping plate, and the other end penetrates the side wall of the connecting component to form an operation unit protruding outward;

[0028] A spring is also arranged in the cavity. The spring is located at the end where the linkage unit is connected to the operation unit and is always in a compressed state.

[0029] In the above solution, the second clamping plate and the operation unit are linked through the linkage unit, enabling technicians to more conveniently control the second clamping plate to move away from the first clamping plate, simplifying the operation of releasing the clamping of the scraper fixing fixture and improving the use experience of technicians; moreover, the spring that provides the tendency for the second clamping plate and the first clamping plate to move towards each other and the linkage unit that realizes the linkage are both hidden inside the connecting component, improving the aesthetics of the scraper fixing fixture.

[0030] Furthermore, the scraper fixing fixtures are arranged in pairs and clamp the scraper from the opposite sides of the scraper respectively. The push rod is provided with fixing devices respectively cooperating with the two scraper fixing fixtures.

[0031] In the above solution, the paired scraper fixing fixtures can more stably clamp the scraper and ensure that the scraper and the push rod are in a stable synchronous movement state.

[0032] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art.

[0033] 1. The scraper is fixed on the scraper fixing fixture and connected to the push rod through the cooperation of the scraper fixing fixture and the fixing device, so that the scraper and the push rod are always in a synchronous movement state when connected. The scraper will not shift during the coating process due to mismatch with the pole piece coating equipment, improving the coating efficiency and coating quality; and the scraper fixing fixture and the fixing device are separately arranged, which is convenient for technicians to disassemble and install the scraper and reduces the operation difficulty.

[0034] 2. The fixing device is slidably arranged on the track extending along the length direction of the push rod and locked by the first locking unit when fixing is required, so that the position of the fixing device on the push rod can be freely adjusted according to actual use requirements. When setting two or more scraper fixing fixtures to fix the scraper, the position of the fixing device can be adjusted to match scrapers of different sizes, improving the versatility of the pole piece coating equipment.

[0035] 3. There is always a tendency for the first clamping plate and the second clamping plate on the scraper fixing fixture to move closer to each other, which can more firmly clamp the scraper. The operating unit and the second clamping plate are connected through a linkage unit in the connecting rod, and technicians do not need to pull the second clamping plate to control the distance between the first clamping plate and the second clamping plate, reducing the probability of deformation and damage of the second clamping plate and improving the clamping convenience and service life of the scraper fixing fixture.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0044] In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0045] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0046] In the description of the utility model, without special instructions, the term "A and / or B" is usually understood, and its meaning includes: only A, only B, and the situation where A and B exist simultaneously.

[0047] In the description of the utility model, without special instructions. The term "blade" refers to a fixed blade with an unadjustable coating thickness.

[0048] In the description of the present utility model, unless otherwise clearly defined and limited, the "pole piece coating equipment" refers to a small coating machine for laboratory pole piece coating. The small coating machine has a push rod movably arranged along the coating working surface. During coating, the scraper is pushed by the push rod to move for coating.

[0049] The present utility model provides a pole piece coating equipment with a universal scraper, as Figure 1 shown, which includes a fixing device 2 arranged on the push rod 1 and a scraper fixing clamp 3 cooperating with the fixing device 2; the scraper fixing clamp 3 is connected to the fixing device 2, used for clamping the scraper 4 and cooperating with the fixing device 2 to connect the scraper 4 with the push rod 1.

[0050] Before the coating starts, the technician first fixes the scraper 4 on the scraper fixing clamp 3, then places the scraper 4 and the scraper fixing clamp 3 together on the pole piece coating equipment, and then connects the scraper fixing clamp 3 with the fixing device 2 on the push rod 1, thus realizing the connection between the scraper 4 and the push rod 1. The connected scraper 4 and push rod 1 always move synchronously. Even if the scraper 4 and the pole piece coating equipment do not match, the scraper 4 will not shift during the coating process, improving the universality of the pole piece coating equipment. Whether the scraper 4 and the pole piece coating equipment match or not, the coating can be successfully completed without affecting the coating efficiency and coating quality due to the shift of the scraper 4.

[0051] Moreover, in the above solution, the fixing of the scraper 4 does not need to be completed on the pole piece coating equipment. During the fixing process of the scraper 4, it will not rub against the pole piece coating equipment to form scratches, effectively avoiding pole piece wrinkles or even breakage caused by scratches.

[0052] Next, in combination with Figures 1 to 6 specific embodiments are used to further illustrate the present utility model.

[0053] Embodiment 1

[0054] As an embodiment of the present utility model, this embodiment provides a pole piece coating equipment with a universal scraper, in which the fixing device 2 is slidably arranged on the push rod 1.

[0055] In this embodiment, as Figure 2 and Figure 3As shown, a track 101 extending along the length direction of the push rod 1 is provided on the push rod 1. The fixing device 2 includes an adjusting component 201 and a fixing component 202 connected to the adjusting component 201 for connecting the blade fixing fixture 3. The adjusting component 201 cooperates with the track 101 and is slidably arranged relative to the push rod 1 along the extending direction of the track 101. Technicians can adjust the position of the fixing device 2 according to actual needs, thereby controlling the coating position of the blade 4; both ends of the track 101 are open, and the adjusting component 201 can be removed from the track 101 through the opening, realizing the detachable connection between the fixing device 101 and the push rod 1, facilitating technicians to carry out maintenance and repair, and enabling the separate replacement of the push rod 1 or the fixing device 2, reducing the maintenance cost.

[0056] To prevent the fixing device 2 from falling off in the direction perpendicular to the track 101, the cross-section of the track 101 is set to a convex shape. The cross-sectional shape of the adjusting component 201 is the same as that of the track 101, and the width of the wider part of the cross-section of the adjusting component 201 is greater than the width of the narrower part of the cross-section of the track 101; at the same time, to balance the sliding flexibility of the fixing device 2 in the track 101 and the stability of the connection between the fixing device 2 and the push rod, the cross-section of the adjusting component 201 is set slightly smaller than the cross-section of the track 101. On the one hand, it enables the fixing device 2 to move smoothly in the track 101, and on the other hand, it will not cause unnecessary shaking of the fixing device 2 relative to the track 101 due to excessive size differences, maintaining the relative static state of the blade 4 and the push rod 1.

[0057] A threaded hole penetrating along the direction perpendicular to the bottom wall of the track 101 is provided on the adjusting component 201. The first locking unit 2011 is a screw passing through the adjusting component 201 through the threaded hole. The length of the screw is greater than the length of the threaded hole, so that the adjusting component 201 has a locked state in which it is relatively locked with the track 101 through the screw. In the locked state, the screw protrudes from the side of the adjusting component 201 close to the bottom wall of the track 101 and abuts against the bottom wall of the track 101. As the screw extends, the adjusting component 201 moves away from the bottom wall and abuts against the interface between the wider part and the narrower part of the convex track 101, realizing the locking of the fixing device 2 on the track 101 through friction.

[0058] The fixing device 2 also includes a fixing component 202 for connecting the blade fixing fixture 3. The fixing component 202 has a circular through-hole penetrating through it, as Figure 4 shown, the blade fixing fixture 3 includes a cylindrical connecting rod 301 made of a rigid material. The cross-sectional size of the connecting rod 301 is adapted to the size of the through-hole. When the fixing device 2 and the blade fixing fixture 3 are connected, the connecting rod 301 extends into the through-hole and contacts the inner wall of the through-hole, realizing a stable connection through the friction between the connecting rod 301 and the inner wall of the through-hole.

[0059] In other embodiments, the cross-sectional shape of the connecting component 301 and the shape of the through hole can be set to be oval, rectangular, triangular, etc. according to actual usage requirements or based on production convenience. Also, in order to improve the connection reliability and increase the friction between the connecting component 301 and the fixing component 202, the cross-section of the connecting component 301 can be set to other regular or irregular polygons.

[0060] To further improve the connection stability between the connecting rod and the fixing component 202, a second locking unit 2021 having the same structure as the first locking unit 2011 is also provided on the fixing component 202. Specifically, the fixing component 202 has a threaded hole penetrating the circumferential wall of the through hole, and the second locking unit 2021 is a screw that matches the threaded hole. The length of the screw is greater than the length of the threaded hole. By rotating the screw, the friction between the fixing component 202 and the blade fixing fixture 3 can be increased or decreased. Compared with relying only on the friction between the through hole and the connecting component 301, the stable connection between the blade fixing fixture 3 and the fixing device 2 can be realized more reliably, ensuring that the blade 4 and the push rod 1 always remain relatively stationary during the coating process.

[0061] In other embodiments, the first locking unit 2011 and the second locking unit 2021 can also be different, and the structures of the first locking unit 2011 and the second locking unit 2021 can be adjusted according to actual situations. For example, other conventional locking structures such as pin holes, buckles, mortise and tenon joints, etc. can be used as the first locking unit 2011 and the second locking unit 2021. Based on the known technical principles of the present invention, the conventional improvements and replacements made to the structures of the first locking unit 2011 and the second locking unit 2021 also fall within the protection scope of the present invention.

[0062] As Figure 4 shown, the blade fixing fixture 3 further includes a clamping component for clamping the blade 4. The clamping component is a first clamping plate 302 and a second clamping plate 303 that are spaced along the length direction of the connecting component 301. The gap between the first clamping plate 302 and the second clamping plate 303 matches the width of the blade 4, clamping the blade 4 from both sides of the blade 4, limiting the displacement of the blade 4 along the length direction of the connecting component 301, and at the same time fixing the blade 4 in the plane perpendicular to the connecting component 301 through the friction between the first clamping plate 302, the second clamping plate 303 and the blade 4. Thus, the blade 4 can move synchronously with the push rod 1 under the push of the push rod 5.

[0063] Embodiment 2

[0064] As another embodiment of the present invention, the following further improvements are made on the basis of Embodiment 1.

[0065] In this embodiment, the second clamping plate 303 is slidably arranged relative to the connecting component 301 along the length direction of the connecting component 301, and always has a tendency to move close to the first clamping plate 302. The movement tendency of the first clamping plate 302 and the second clamping plate 303 approaching each other further increases the friction between the scraper 4, which can better achieve the clamping of the scraper 4.

[0066] Specifically, Figure 5 and Figure 6 As shown, the first clamping plate 302 is located at one end of the connecting component 301, and the connecting component 301 has a cavity inside. The cavity has a linkage unit 304 that can be slidably arranged along the length direction of the connecting component 301, and a limiting opening that connects the cavity with the outside. The linkage unit 304 extends from the limiting opening and is connected to the second clamping plate 303. The sliding path of the second clamping plate 303 is limited by the limiting opening; a spring 306 is provided at one end of the linkage unit 304 away from the second clamping plate 303, and the spring 306 is always in a compressed state. The linkage unit 304 continuously presses the second clamping plate 303 to the first clamping plate 303. The second clamping plate 303 applies a force to slide toward the first clamping plate 302; when clamping the fixture, the technician grabs the second clamping plate 303, overcomes the rebound force of the spring 306 and controls the second clamping plate 303 to slide in the direction away from the first clamping plate 302. When the distance between the first clamping plate 302 and the second clamping plate 303 is sufficient to accommodate the scraper 4, the scraper 4 is placed between the two and the second clamping plate 303 is released. Under the action of the rebound force of the spring 306, the first clamping plate 302 and the second clamping plate 303 meet and approach from both sides of the scraper 4 to firmly clamp the scraper 4.

[0067] In the above scheme, in order to avoid a violent collision between the second clamping plate 303 and the scraper 4, the technician needs to grab the second clamping plate 303 and slowly remove the force controlling the second clamping plate 303 to move away from the first clamping plate 302. In this process, it is easy to clamp the hand between the scraper 4 and the second clamping plate 303 due to improper control; in order to avoid clamping the hand without control, the second clamping plate 303 collides with the scraper 4 under the action of the rebound force, which is easy to cause damage to the scraper 4, or cause the second clamping plate 303 to deform, which will significantly affect the clamping stability in the long run; in order to solve this problem, the outer side of the connecting component 301 also has an operating unit 305 that can be slidably arranged relative to the connecting component 301, the operating unit 305 is connected to the linkage unit 304, and the connecting component 301 is correspondingly provided with a limit opening matching the sliding path of the operating unit 305; the technician controls the sliding of the second clamping plate 303 through the operating unit 305, which is more convenient and safer.

[0068] In this embodiment, the second clamping plate 303 and the operating unit 305 are respectively located on both sides of the connecting component 301. Those skilled in the art can adjust the relative positions of the second clamping plate 303 and the operating unit 305 according to the actual operating conditions on the basis of knowing the technical principle of the present utility model. The solutions obtained by simply changing the relative positions of the two also fall within the protection scope of the present utility model.

[0069] In addition, the blade fixing jig 3 mentioned in this embodiment can also be combined with the second embodiment to obtain other embodiments, and the embodiments obtained by combining with the second embodiment also fall within the protection scope of the present utility model.

[0070] Embodiment Three

[0071] As another embodiment of the present utility model, the following further improvements are made on the basis of the second embodiment.

[0072] In this embodiment, there are two independent fixing devices 2 in the track 101, and the pole piece coating equipment correspondingly has two blade fixing jigs 3. The two blade fixing jigs 3 respectively clamp the blade 4 from both sides of the blade 4, further improving the clamping stability of the blade 4; the two blade fixing jigs 3 are respectively matched with the two fixing devices 2 through connecting parts. Since the two fixing devices 2 are independent of each other, the distance between the two fixing devices 2 can be correspondingly adjusted according to the width of the blade 4 to achieve sufficient clamping and fixing of blades 4 of different sizes.

[0073] Furthermore, since the two blade fixing jigs 3 are respectively matched with the two fixing devices 2, there may be a situation where the distances between the clamping components and the fixing component 202 are inconsistent, causing the blade 4 to be non-parallel to the push rod 1, thereby affecting the coating effect. For this reason, scale marks are also provided on the connecting component 301. The blade fixing jigs 3 that clamp the blade 4 from both sides of the blade 4 are connected to the fixing component 202 at the same scale, ensuring that the blade 4 and the push rod 1 are in a parallel state.

[0074] In this embodiment, the scale marks are sequentially arranged from the end of the connecting component 301 where the first clamping plate 302 is provided along the length direction of the connecting component 301 away from the first clamping plate 302. At this time, on multiple blade fixing jigs 3, the distances from the positions with the same scale to the first clamping plate 302 are the same, which is convenient for technicians to confirm whether the blade 4 and the push rod 1 are parallel to each other; in other embodiments, the setting method of the scale marks can also be adjusted according to the actual situation, for example, starting from the end far from the first clamping plate 302.

[0075] In addition, the blade fixing jig 3 mentioned in this embodiment can also be combined with the first embodiment and the second embodiment to obtain other embodiments, and the other embodiments obtained by combining with the first embodiment and the second embodiment also fall within the protection scope of the present utility model.

[0076] The above are only the preferred embodiments of the present invention, and there is no restriction on the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above to form equivalent embodiments of equivalent changes. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
