Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of laminated battery processing, in particular to a dust removal method for batch processing of die-cut polar sheets. BACKGROUND

[0002] In the production process of laminated batteries, a die-cutting machine is used to cut the roll-shaped material into single polar sheets of a size suitable for production. The single polar sheets are then sent to a material punching mechanism by a conveying belt, so that the material punching mechanism can punch multiple polar sheets into a magazine one by one, allowing the multiple polar sheets to be stacked in the magazine for subsequent rapid feeding of the laminated battery machine.

[0003] However, a large amount of dust is generated during the cutting process and the polar sheet clamping process, which causes the polar sheets to easily stick to dust and cause short circuits in the battery. Therefore, in order to solve the above problems, some scholars add a dust removal assembly to the die-cutting machine to achieve better dust removal effect on the polar sheets.

[0004] As disclosed in Chinese Patent No. CN 115534003 A, a die-cutting device and dust removal device and method are provided, which enable the front dust removal mechanism and the back dust removal mechanism to effectively remove dust from the polar sheets. However, since the front dust removal mechanism and the back dust removal mechanism use dust removal fans to remove dust from the front and back of the polar sheets, they cannot effectively remove dust from the side walls of the polar sheets, i.e., there is a problem of poor dust removal effect.

[0005] In order to improve the dust removal effect on the polar sheets, as disclosed in Chinese Patent No. CN 102489457 A, a laminated battery polar sheet dust removal device is provided, which adds a first lower brush below the conveying belt. Since the first brush has bristles on both sides, the bristles are in contact with the lower surface of the polar sheets on both sides of the conveying belt to achieve dust removal on both sides of the polar sheets. However, it cannot achieve dust removal on the other two side walls of the polar sheets, and there is still a problem of poor dust removal effect.

[0006] In addition, although the above-mentioned laminated battery polar sheet can create a local negative pressure environment, since the polar sheet is conveyed in a negative pressure environment, there is still a problem of easy crease deformation of the polar sheet due to the force of the conveying belt when the negative pressure is strong. Moreover, the conventional polar sheet dust removal device can only remove dust from the side walls of one polar sheet at a time, which has a problem of poor dust removal efficiency and cannot achieve mass dust removal effect, resulting in the inability to meet the demand for automatic rapid material feeding. SUMMARY

[0007] The purpose of the present disclosure is to overcome the deficiencies in the prior art, provide a dust removal method for batch processing die-cut polar pieces, which not only improves the efficiency of single dust removal of the dust removal equipment, but also facilitates the flexible entry and exit of the polar piece B into the blowing-suction-sweeping processing cavity, improves the adaptability to different specifications of the polar piece B, reduces the dust escape, secondary pollution of the polar piece B after dust removal, and wear of the polar piece B, and better ensures the dust removal effect of single polar piece A and the product quality of batch processing die-cut polar pieces.

[0008] The purpose of the present disclosure is achieved by the following technical solutions:

[0009] A dust removal method for batch processing die-cut polar pieces, comprising the following steps:

[0010] Stacking multiple die-cut polar pieces A on a carrier plate of a cartridge to form a certain thickness of polar pieces B on the carrier plate, wherein a containing cavity is formed in the cartridge, and the carrier plate is movably arranged in the containing cavity;

[0011] The polar pieces B and the cartridge are sent together to the jacking mechanism of the dust removal equipment;

[0012] The carrier plate is jacked up to a preset dust removal position by the jacking mechanism, so that the polar pieces B are tightly fixed between the pressing mechanism of the dust removal equipment and the jacking mechanism;

[0013] The first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism of the dust removal equipment are driven to move close to the polar pieces B, so that the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism wrap the polar pieces B in a relatively closed blowing-suction-sweeping processing cavity;

[0014] Then, the blowing-ion wind operation and the negative pressure vacuum operation are performed on the blowing-suction-sweeping processing cavity at the same time;

[0015] Then, soft hair brushes are used to clean the four peripheral side walls of the polar pieces B;

[0016] After the cleaning operation is completed, the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are driven to move away from the polar pieces B to open the blowing-suction-sweeping processing cavity;

[0017] The carrier plate is lowered back into the containing cavity of the cartridge by the jacking mechanism to complete the dust removal operation of the polar pieces B.

[0018] Compared with the prior art, the present disclosure has at least the following advantages:

[0019] 1) By stacking a plurality of pole pieces A on the carrier plate of the magazine, a certain thickness of pole pieces B can be obtained on the carrier plate, when the pole pieces B and the magazine are sent to the lifting mechanism of the dust removal equipment together, and then the carrier plate is lifted to the preset position by the lifting mechanism, so that the pole pieces B can be tightly fixed between the pressing mechanism and the lifting mechanism, so that the four side walls of the pole pieces B can be exposed, then the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are driven to move close to the pole pieces B, so that the pole pieces B are wrapped in a relatively closed blowing-suction-sweeping processing cavity, then the blowing ion wind operation and the negative pressure vacuum operation are carried out on the blowing-suction-sweeping processing cavity at the same time, so that the blowing ion wind operation can effectively blow off the dust on the four side walls of the pole pieces B, and under the negative pressure vacuum operation, the blowing-suction-sweeping processing cavity can be in a relatively negative pressure environment, effectively avoiding the dust blown off by the blowing ion wind operation from rising upward to cause secondary pollution of the dust to the pole pieces, and avoiding the accumulation of dust in the blowing-suction-sweeping processing cavity to affect the dust removal effect of the pole pieces B, then the soft brush is used to clean the four side walls of the pole pieces B, so that the soft brush can completely remove the dust adhered to the four side walls of the pole pieces B, effectively avoiding the phenomenon that the dust with strong adhesion cannot be completely removed, so that the blowing-suction-sweeping operation is completed on the pole pieces B in turn, not only realizing the overall dust removal effect on the four side walls of the pole pieces B and improving the dust removal effect of the pole pieces B, but also effectively avoiding the phenomenon that the dust removal effect of the soft brush on the pole pieces B is reduced due to the accumulation of dust on the soft brush caused by the soft brush cleaning.

[0020] 2) Since the pole pieces B do not need to be conveyed during the dust removal process, the effect of the conveying belt on the pole pieces B can be reduced, thereby effectively avoiding the problem that the pole pieces are easily deformed due to the effect of the conveying belt in a strong negative pressure environment, and further better ensuring the product quality of the single pole piece.

[0021] 3) Since the plurality of pole pieces A after die cutting are stacked into a certain thickness of pole pieces B, on the one hand, the pressing mechanism and the lifting mechanism are clamped and fixed to ensure that the pole pieces B do not easily fall off during the dust removal process, and on the other hand, since the thickness of the pole pieces B is relatively thick, the contact area of the pole pieces B and the soft brush is increased, not only improving the efficiency of single dust removal of the dust removal equipment, but also realizing the dust removal effect of batch processing of die-cut pole pieces, and better meeting the demand of automatic fast material feeding; and also can avoid the problem that the pole pieces B are easily deformed due to the large cleaning force of the soft brush, so as to better ensure the product quality of the single pole piece A.

[0022] 4) due to the cooperation of the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, on the one hand, it ensures that the blowing-suction-sweeping treatment cavity is in a relatively closed space, reduces the opening area of the blowing-suction-sweeping treatment cavity, that is, reduces the phenomenon of large-area dust escape, thereby effectively avoiding the problem of serious pollution of the cleanliness of the production workshop; on the other hand, it is beneficial to the entry and exit of the pole piece B into the blowing-suction-sweeping treatment cavity, so as to ensure that the pole piece B enters and exits the blowing-suction-sweeping treatment cavity more flexibly, and can well adapt to the treatment of pole pieces B of various specifications, that is, the adaptability to pole pieces B of different specifications is improved; on the other hand, it also reduces the contact and collision of the pole piece B with the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, effectively avoids the problem of secondary pollution of the pole piece B after dust removal, and well ensures the dust removal effect of the single pole piece A.

[0023] 5) due to the use of soft hair brushes, the four peripheral side walls of the pole piece B can be comprehensively cleaned, and the wear of the four peripheral side walls of the pole piece B can be reduced, so as to avoid damaging the four peripheral side walls of the pole piece B, and better ensure the product quality of the single pole piece A.

DETAILED DESCRIPTION

[0036] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thorough and comprehensive.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] It should be noted that most current electrode dust removal devices consist of brush cleaning + negative pressure vacuuming + conveyor belt, as mentioned in the background art Chinese patent number CN 102489457 A which discloses a dust removal device for stacked battery electrodes, and also in the stacked battery electrode cleaning device disclosed in Chinese patent number CN 102500580 A. However, the method of using brush cleaning + negative pressure vacuuming + conveyor belt is problematic. As mentioned in the background art, under strong negative pressure, the conveyed electrode B is prone to creases and deformation under the action of the conveyor belt, and it is impossible to achieve a comprehensive dust removal effect on the four sides of the electrode.

[0040] Therefore, to solve the above problems, a new type of dust removal device has emerged on the market. For example, Chinese Patent No. CN103170959B discloses a material box with a dust removal device, specifically disclosing a dust removal chamber, a vacuum cleaner, a brush, and a blower mechanism. It also discloses an electrode box, allowing multiple electrodes to be placed inside, and then placed in the dust removal chamber for blowing, sweeping, and suction operations to achieve dust removal from the electrodes. However, from the above-mentioned material box… Figure 3 It is known that because the dust removal chamber has openings at the top and bottom, dust can easily escape from the openings, causing serious pollution problems in the cleanliness of the production workshop. In addition, the dust removal chamber of the material box is fixed, which is not conducive to users loading or unloading, and has poor adaptability.

[0041] To solve the above technical problems, the present disclosure adopts the cooperation of the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, which on the one hand ensures that the blowing-suction-sweeping processing cavity is in a relatively closed space, reduces the opening area of the blowing-suction-sweeping processing cavity, that is, reduces the phenomenon of large-area dust escape, thereby effectively avoiding the problem of serious pollution of the cleanliness of the production workshop; on the other hand, it is beneficial to the entry and exit of the pole piece B into the blowing-suction-sweeping processing cavity, so as to ensure that the pole piece B enters and exits the blowing-suction-sweeping processing cavity more flexibly, and can well adapt to the processing of pole pieces B of various specifications, that is, the adaptability to pole pieces B of different specifications is improved; on the other hand, it also reduces the contact and collision of the pole piece B with the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, effectively avoids the problem of secondary pollution of the pole piece B after dust removal, and better ensures the dust removal effect of the single pole piece A.

[0042] Further, since the soft brush can comprehensively clean the four peripheral side walls of the pole piece B, it also reduces the wear of the four peripheral side walls of the pole piece B, so as to avoid damaging the four peripheral side walls of the pole piece B, and better ensure the product quality of the single pole piece A.

[0043] Please refer to Figure 1 In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments. The dust removal method of batch processing die-cut pole pieces of an embodiment includes part or all of the following steps:

[0044] S101, stack the plurality of die-cut pole pieces A on the carrier plate of the clip, so as to form a certain thickness of pole pieces B on the carrier plate, wherein the clip forms a receiving cavity, and the carrier plate is movably arranged in the receiving cavity.

[0045] It can be understood that the conventional die-cutting machine is used to cut the material roll, and the size of the pole piece B required for production can be obtained, and the die-cutting machine also includes a dust removal assembly to achieve the preliminary dust removal effect on the surface of the die-cut piece A. Then, the plurality of pole pieces are sequentially punched into the clip by using the material punching mechanism, so as to stack the plurality of die-cut pole pieces A on the carrier plate of the clip, thereby forming a certain thickness of pole pieces B on the carrier plate. Although the dust removal assembly of the die-cutting machine achieves the dust removal effect on the surface of the single pole piece A, when the single pole piece after dust removal is punched into the clip, on the one hand, the punched single pole piece A is prone to collision with the clip, causing secondary pollution of dust and affecting the dust removal effect of the single pole piece A; on the other hand, the dust removal assembly in the die-cutting machine cannot achieve comprehensive dust removal effect on the four peripheral side walls of the single pole piece A. Therefore, in the present disclosure, the plurality of die-cut pole pieces A are stacked on the carrier plate of the clip to form a certain thickness of pole pieces B on the carrier plate, so as to achieve comprehensive blowing-suction-sweeping dust removal operation on the four peripheral side walls of the pole piece B.

[0046] In the embodiment, the accommodating cavity is formed in the magazine, so that the plurality of die-cut polar pieces A can be neatly stacked in the magazine. The carrier plate is movably arranged in the accommodating cavity, so that the lifting mechanism can lift and lower the carrier plate. In other words, the lifting mechanism can lift or lower the carrier plate to push the polar piece B into the blowing-suction-sweeping processing cavity or send the polar piece B back to the magazine.

[0047] S102, the polar piece B and the magazine are sent to the lifting mechanism of the dust removal equipment. It can be understood that after the plurality of polar pieces A are stacked in the magazine, the magazine and the polar piece B can be placed on the lifting mechanism of the dust removal equipment by a mechanical hand or manually, so that the subsequent lifting mechanism can lift and lower the carrier plate.

[0048] In one of the embodiments, when the magazine is placed on the lifting mechanism, the ejector rod of the lifting mechanism is correspondingly arranged with the carrier plate, so that the lifting mechanism can push the polar piece placed on the carrier plate into the blowing-suction-sweeping processing cavity or send the polar piece B back to the magazine when lifting and lowering.

[0049] S103, the carrier plate is lifted to a preset dust removal position by the lifting mechanism, so that the polar piece B is tightly fixed between the polar piece mechanism and the lifting mechanism of the dust removal equipment.

[0050] It can be understood that the carrier plate is lifted by the ejector rod of the lifting mechanism to realize the lifting operation of the carrier plate, so as to drive the polar piece B to lift and lower, so that the polar piece B can be tightly fixed between the polar piece mechanism and the lifting mechanism, that is, the polar piece B is clamped and fixed, and at the same time, the four side walls of the polar piece B can be exposed, so that the subsequent blowing ion wind operation, negative pressure vacuum operation and cleaning operation can completely remove the dust on the four side walls of the polar piece B, so as to achieve good dust removal effect.

[0051] In the embodiment, the preset dust removal position refers to that when the polar piece B is tightly fixed between the polar piece mechanism and the lifting mechanism, the polar piece B can be located in the blowing-suction-sweeping processing cavity, and the position of the soft brush is correspondingly arranged, so that the soft brush can completely clean the four side walls of the polar piece B. At the same time, the ion inclined air knife of the blowing ion wind operation is located above the polar piece B, so as to completely blow off the dust on the four side walls of the polar piece B, and the exhaust pipe of the negative pressure vacuum operation is located below the polar piece B, so as to completely suck the dust in the blowing-suction-sweeping processing cavity by the exhaust pipe, so as to ensure the cleanliness of the blowing-suction-sweeping processing cavity, and effectively avoid the problem of secondary pollution caused by the dust adhering to the four side walls of the polar piece B again.

[0052] S104, drive the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism of the dust removal equipment to move close to the pole piece B, so that the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism wrap the pole piece B in a relatively closed blow-suction-sweep processing cavity, so that the pole piece B can be in a relatively sealed space during the subsequent dust removal process, so as to effectively and comprehensively remove the dust on the four peripheral side walls of the pole piece B.

[0053] It should be noted that, as disclosed in Chinese Patent No. CN103170959B, a material box with a dust removal device is disclosed, and specifically a dust removal cavity, a dust collector, a brush and a blowing mechanism are disclosed, and a pole piece box is also disclosed, so that multiple pole pieces can be placed in the pole piece box, and then the blowing and sweeping operation in the dust removal cavity is performed to achieve the dust removal effect of the pole pieces. However, from the above material box, Figure 3 It can be seen that, since the dust removal cavity has openings at the top and bottom, dust is easy to escape from the openings, causing serious pollution problems in the cleanliness of the production workshop, and the dust removal cavity of the material box is fixed, which is not convenient for the user to load or take out, and has poor adaptability.

[0054] In order to solve the above technical problems, in the present disclosure, the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are used in cooperation, on the one hand, to ensure that the blow-suction-sweep processing cavity is in a relatively closed space, reducing the opening area of the blow-suction-sweep processing cavity, that is, reducing the phenomenon of large-area dust escaping, thereby effectively avoiding the problem of serious pollution in the cleanliness of the production workshop; on the other hand, it is beneficial to the pole piece B to enter and exit the blow-suction-sweep processing cavity, so as to ensure that the pole piece B enters and exits the blow-suction-sweep processing cavity more flexibly, and can well adapt to the processing of pole pieces B of various specifications, that is, the adaptability to pole pieces B of different specifications is improved; on the other hand, it also reduces the contact and collision between the pole piece B and the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, effectively avoiding the problem of secondary pollution of the pole piece B after dust removal, so as to well ensure the dust removal effect of the single pole piece A.

[0055] S105, then simultaneously perform ion blowing operation and negative pressure vacuum operation on the blow-suction-sweep processing cavity, so that the blow-suction-sweep processing cavity can be in a relatively negative pressure environment, effectively avoiding the phenomenon that the dust blown off by the ion blowing operation is raised upward to cause secondary pollution of the pole piece by the dust, and avoiding the accumulation of dust in the blow-suction-sweep processing cavity to affect the dust removal effect of the pole piece B.

[0056] S106, then use a soft brush to sweep the four peripheral side walls of the pole piece B.

[0057] It can be understood that firstly, the blowing-ion wind operation and the negative pressure vacuum operation are simultaneously performed on the blowing-suction-sweeping processing cavity to better remove the dust with weak adhesion around the pole piece B and to loosen the dust with strong adhesion. Then, the soft brush is used to sweep the dust around the pole piece B, so that the dust around the pole piece B can be completely removed, and the phenomenon that the dust with strong adhesion cannot be completely removed is effectively avoided. In this way, under the premise that the soft brush can completely sweep the dust around the pole piece B, the abrasion of the pole piece B is reduced, the damage to the pole piece B is avoided, and the product quality of the single pole piece A is better ensured.

[0058] S107, after the sweeping operation is completed, the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are driven to move away from the pole piece B to open the blowing-suction-sweeping processing cavity, so that the pole piece B can be exposed above the clip to enable the lifting mechanism to lower the carrier plate back to the accommodating cavity of the clip.

[0059] S108, the carrier plate is lowered back to the accommodating cavity of the clip by the lifting mechanism, so that the pole piece B after dust removal can be sent back to the clip, thereby completing the blowing-suction-sweeping dust removal operation of the pole piece B, and effectively avoiding the problem that the pole piece B after dust removal is easily polluted by dust again.

[0060] It can be understood that, compared with the traditional material box with a dust removal device, since the dust removal cavity has openings at the top and bottom, dust is easy to escape from the openings, causing serious pollution problems in the production workshop. Therefore, the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are used in cooperation, on the one hand, to ensure that the blowing-suction-sweeping processing cavity is in a relatively closed space, reducing the opening area of the blowing-suction-sweeping processing cavity, i.e. reducing the phenomenon of large-area dust escape, thereby effectively avoiding the problem of serious pollution of the cleanliness of the production workshop; on the other hand, it is beneficial to the pole piece B to enter and exit the blowing-suction-sweeping processing cavity, so as to ensure that the pole piece B enters and exits the blowing-suction-sweeping processing cavity more flexibly, which can well adapt to the processing of pole pieces B of various specifications, i.e. improving the adaptability to pole pieces B of different specifications; on the other hand, it also reduces the contact and collision between the pole piece B and the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, effectively avoiding the problem of secondary pollution of the pole piece B after dust removal, and better ensuring the dust removal effect of the single pole piece A.

[0061] It can also be understood that first, a plurality of pole pieces A are stacked on the carrier plate of the magazine, a certain thickness of pole pieces B can be obtained on the carrier plate, then the pole pieces B and the magazine are sent to the jacking mechanism of the dust removal equipment together, then the carrier plate is jacked to a preset position by the jacking mechanism, so that the pole pieces B can be tightly fixed between the pressing mechanism and the jacking mechanism, so that the four side walls of the pole pieces B can be exposed, then the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are driven to move close to the pole pieces B, so that the pole pieces B are wrapped in the relatively closed blowing-suction-sweeping processing cavity, then the blowing ion wind operation and the negative pressure vacuum operation are performed on the blowing-suction-sweeping processing cavity at the same time, so that the blowing ion wind operation can effectively blow off the dust on the four side walls of the pole pieces B, and under the negative pressure vacuum operation, the blowing-suction-sweeping processing cavity can be in a relatively negative pressure environment, effectively avoiding the dust blown off by the blowing ion wind operation from rising upward to cause secondary pollution of the pole pieces, avoiding the accumulation of dust in the blowing-suction-sweeping processing cavity to affect the dust removal effect of the pole pieces B, then the soft brush is used to clean the four side walls of the pole pieces B, so that the soft brush can completely clean the dust adhered to the four side walls of the pole pieces B, effectively avoiding the phenomenon that the dust with strong adhesion cannot be completely removed, so as to sequentially complete the blowing-suction-sweeping operation of the pole pieces B, not only realizing the overall dust removal effect of the four side walls of the pole pieces B and improving the dust removal effect of the pole pieces B, but also effectively avoiding the phenomenon that the dust removal effect of the soft brush on the pole pieces B is reduced due to the accumulation of dust on the soft brush caused by the use of the soft brush for cleaning first.

[0062] It is worth mentioning that since the pole pieces B do not need to be conveyed during the dust removal process, the effect of the conveying belt on the pole pieces B can be reduced, thereby effectively avoiding the problem that the pole pieces are easily deformed due to the effect of the conveying belt in a strong negative pressure environment, and further better ensuring the product quality of the single pole piece.

[0063] Further, since the plurality of pole pieces A after die cutting are stacked into pole pieces B with a certain thickness, on the one hand, the pressing mechanism and the jacking mechanism are clamped and fixed to ensure that the pole pieces B do not easily fall off during the dust removal process, and on the other hand, since the thickness of the pole pieces B is relatively thick, the contact area of the pole pieces B and the soft brush is increased, not only improving the efficiency of single dust removal of the dust removal equipment, but also realizing the dust removal effect of batch processing of die-cut pole pieces, thereby better meeting the demand for automatic fast material feeding; and also avoiding the problem that the pole pieces B are easily deformed due to the large cleaning force of the soft brush, thereby better ensuring the product quality of the single pole piece A.

[0064] Further, since the soft brush can comprehensively clean the four side walls of the pole pieces B under the premise of being able to comprehensively clean the four side walls of the pole pieces B, the abrasion of the four side walls of the pole pieces B can be reduced, thereby avoiding damage to the four side walls of the pole pieces B, and better ensuring the product quality of the single pole piece A.

[0065] In one embodiment, when cleaning the four sides of electrode B with soft brushes, four soft brushes are used to clean the four sides of electrode B back and forth multiple times to achieve a comprehensive dust removal effect on the four sides of electrode B.

[0066] In one embodiment, four soft brushes are used to clean the four sides of electrode B back and forth 2 to 4 times. It is understood that if the number of cleanings is less than 2, a good dust removal effect cannot be achieved on the four sides of electrode B; if the number of cleanings is more than 4, damage to the four sides of electrode B is likely to occur. Therefore, in this disclosure, by controlling the number of back and forth cleanings of the four soft brushes on the four sides of electrode B to 2 to 4 times, a good dust removal effect is ensured while minimizing damage to the four sides of electrode B.

[0067] In one embodiment, a downward-sloping ionizing airflow is used to ionize electrode B. It is understood that since the sidewalls of electrode B formed by multiple electrode sheets A stacked together cannot be perfectly aligned, a vertical downward ionizing airflow would not effectively remove dust from the recessed sidewalls of electrode A. Therefore, a downward-sloping ionizing airflow is used to create an ionizing airflow with a certain angle around the sidewalls of electrode B, effectively blowing away dust from the recessed sidewalls of electrode A, thus achieving a more comprehensive dust removal effect on electrode B. Furthermore, the downward-sloping ionizing airflow effectively removes static electricity from electrode B, preventing dust from being easily stirred up after cleaning, ensuring that the swept dust is more thoroughly removed. It also loosens some of the more adhesive dust, ensuring that the soft brush can more easily remove the more adhesive dust later.

[0068] In one embodiment, the downward tilting angle of the ionizing air is 20° to 50°. In a preferred embodiment, the downward tilting angle of the ionizing air is 45°. Specifically, the fan parameters used in conjunction with the ionizing air operation are: pressure 1800 Pa to 2500 Pa, frequency 40 Hz to 60 Hz, flow rate 8 m³ / h to 15 m³ / h, and rotation speed 2000 r / min to 3200 r / min, to ensure that the downward tilting ionizing air can effectively blow away dust from the recessed areas around electrode B.

[0069] It can be understood that, due to the unevenness of the plurality of pole pieces A during the stacking process, when the downwardly inclined ion wind is blocked by a protruding pole piece A, part of the downwardly inclined ion wind will be dispersed around to weaken the dust removal effect of the downwardly inclined ion wind on the side wall of the blocked pole piece B, resulting in poor dust removal effect on the side wall of the pole piece B. Therefore, in one embodiment, when the soft brush cleans the side wall of the pole piece B, the projection of the bristles of the soft brush on the side wall of the pole piece B forms a preset shallow cleaning area, so that the bristles can extend a certain distance into the side wall of the pole piece B during cleaning, better cleaning the dust on the side wall of the recessed pole piece A, and effectively solving the problem of incomplete dust removal on the side wall of the pole piece B due to the blockage of the downwardly inclined ion wind by a protruding pole piece A. It is worth mentioning that the preset shallow cleaning area will not sweep away the active material of the pole piece A during cleaning.

[0070] In one embodiment, in order to achieve comprehensive and dead angle-free dust removal effect on the side wall of the pole piece B, four preset shallow cleaning areas are formed on the side wall of the pole piece B corresponding to the four soft brushes, so that the four soft brushes can better contact the side wall of the recessed pole piece A when cleaning the side wall of the pole piece B, achieving comprehensive and dead angle-free dust removal effect on the side wall of the pole piece B, and effectively solving the problem of incomplete dust removal on the side wall of the pole piece B due to the blockage of the downwardly inclined ion wind by a protruding pole piece A.

[0071] In a preferred embodiment, the range of the preset shallow cleaning area is 5mm-25mm, to ensure that the bristles of the four soft brushes are appropriately in the preset shallow cleaning area of the side wall of the pole piece B, to ensure that the soft brushes do not sweep away the active material of the pole piece A during cleaning, while ensuring comprehensive dust removal effect on the recessed part of the pole piece B, effectively avoiding the problem that the active material of the pole piece A is swept away due to the bristles of the soft brush being too long in the preset shallow cleaning area of the side wall of the pole piece B, and effectively avoiding the problem that the recessed part of the pole piece B cannot be fully cleaned due to the bristles of the soft brush being too short in the preset shallow cleaning area of the side wall of the pole piece B.

[0072] In one embodiment, the number of soft brushes is four, which are a first soft brush, a second soft brush, a third soft brush and a fourth soft brush, and the first soft brush, the second soft brush, the third soft brush and the fourth soft brush are respectively and one-to-one corresponding to the side wall of the pole piece B, to ensure comprehensive cleaning of the side wall of the pole piece B, while reducing the wear of the side wall of the pole piece B, to better ensure the product quality of the single pole piece A.

[0073] It can be understood that if only soft bristles are used to clean the four side walls of the pole piece B, the soft bristles will be deformed after long-term use, which will affect the dust removal of the pole piece B. If only hard bristles are used, the pole piece B will be damaged. Therefore, in one embodiment, the soft bristles include an elastic hard part and a soft bristle cleaning part connected to each other. The elastic hard part is connected to the cleaning arm. In this way, the elastic hard part is not easy to deform during long-term cleaning, and the elastic hard part will automatically recover its shape when it is not in contact with the pole piece B, so as to quickly enter the return stroke of cleaning, so that the soft bristle cleaning part quickly contacts the pole piece B, thereby better ensuring the back-and-forth cleaning effect of the soft bristles. It also ensures that the soft bristles can maintain a good structure for a long time, thereby ensuring the long-term cleaning and dust removal effect of the soft bristles.

[0074] In one embodiment, the length of the elastic hard part and the soft bristle cleaning part is 1:2, so as to ensure that the ratio of the elastic hard part and the soft bristle cleaning part is appropriate, so that the soft bristle cleaning part can be deformed better during cleaning, so as to reduce the friction between the soft bristle cleaning part and the four side walls of the pole piece B, and effectively avoid the phenomenon that the soft bristle cleaning part easily damages the pole piece B during cleaning.

[0075] In one embodiment, the elastic hard part is a silica gel strip, and the soft bristle cleaning part is a wool part, so as to realize the reset of the soft bristle cleaning part, the difficulty of deformation, and the difficulty of damaging the pole piece B.

[0076] In one embodiment, in the step of lowering the bearing plate into the accommodating cavity of the clamping jig by the jacking mechanism, the negative pressure vacuum operation is delayed for 3s-5s.

[0077] It can be understood that if the dusted pole piece B is directly lowered and sent back to the accommodating cavity of the magazine, the dust on the side wall of the accommodating cavity will cause secondary pollution to the pole piece B because the accommodating cavity is not subjected to a dust removal operation. Therefore, in the step of lowering and sending the carrying plate into the accommodating cavity of the magazine by the jacking mechanism, the negative pressure vacuum operation is delayed for 3s-5s, at this time, the pole piece B is exposed above the magazine, and the delayed negative pressure vacuum operation can effectively extract the dust in the magazine, the first frame of the first opening and closing dust removal mechanism, and the second frame of the second opening and closing dust removal mechanism, not only effectively avoiding the secondary pollution of the dust on the side wall of the accommodating cavity of the magazine to the pole piece B, but also effectively avoiding the problem that the dust adheres to the side wall of the first frame and the second frame, affecting the sealing performance of the next closing of the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism, so as to ensure that the dust removal equipment normally enters the next round of dust removal operation, thereby ensuring the continuous batch dust removal operation of the pole piece B, and better meeting the production demand of automation. It is worth mentioning that if the first opening and closing dust removal mechanism and the second opening and closing dust removal mechanism are not tightly closed, on the one hand, the negative pressure vacuum effect cannot be well ensured, resulting in that the pole piece B is easily subjected to secondary pollution of dust due to the accumulation of more dust in the blow-suction-sweep processing cavity, and on the other hand, the dust escapes during the dust removal process, affecting the cleanliness of the production workshop.

[0078] In one embodiment, the pressure of the negative pressure vacuum operation is 0.1MPa-0.5MPa, so as to ensure that the negative pressure of the blow-suction-sweep processing cavity is appropriate, the negative pressure vacuum operation can fully extract the dust in the blow-suction-sweep processing cavity, effectively avoiding the problem that the dust in the blow-suction-sweep processing cavity is accumulated in the blow-suction-sweep processing cavity to cause secondary pollution of the pole piece B, and also avoiding the problem that the negative pressure in the blow-suction-sweep processing cavity is too large to cause the bending deformation of part of the pole piece A, so as to better ensure the product quality of the single pole piece A.

[0079] In one embodiment, in the step of lifting the carrying plate to the preset dust removal position by the jacking mechanism, so that the pole piece B is tightly fixed between the pressing mechanism of the dust removal equipment and the jacking mechanism, the four side walls of the pole piece B are all exposed, so as to realize the overall dust removal effect on the four side walls of the pole piece B.

[0080] In one embodiment, the size of the carrying plate and the pressing plate of the pressing mechanism is smaller than the size of the pole piece B, so as to ensure that the four side walls of the pole piece B are all exposed.

[0081] In a preferred embodiment, the bearing plate and the pressing plate each account for 1 / 3-2 / 3 of the overall size of the pole piece, and under the premise of ensuring that the four peripheral sidewalls of the pole piece B are exposed, the bearing plate and the pressing plate also maximally ensure that the clamping area of the pole piece B is large, effectively reducing the problems of deformation or indentation of the pole piece B under the conditions of negative pressure, ion blowing wind and cleaning, so as to better ensure the product quality and dust removal effect of the single pole piece A.

[0082] In one of the embodiments, the driver of the pressing mechanism is a pneumatic cylinder, and the driver of the lifting mechanism is a servo motor. It can be understood that if the pressing mechanism and the lifting mechanism use servo motors at the same time, the clamping force of the bearing plate and the pressing plate on the pole piece B is relatively large, which causes the clamping part of the pole piece B to be prone to indentation. If the pressing mechanism and the lifting mechanism use pneumatic cylinders at the same time, it is easy to cause the clamping of the bearing plate and the pressing plate on the pole piece B to be unstable. Therefore, in the present disclosure, the driver of the pressing mechanism is a pneumatic cylinder, and the driver of the lifting mechanism is a servo motor, so as to ensure that the clamping force of the bearing plate and the pressing plate on the pole piece B is relatively appropriate. Under the premise of ensuring reliable clamping and fixation of the pole piece B, the problem of the clamping part of the pole piece B being prone to indentation is also improved.

[0083] In one of the embodiments, the air pressure of the pneumatic cylinder is 0.1-0.4 MPa, so as to ensure that the pneumatic cylinder can provide reliable and stable driving force for the pressing plate, so as to reliably clamp and fix the pole piece B under the condition of negative pressure. In a preferred embodiment, in actual application, the pneumatic cylinder is provided by Yadeke Company, especially in cooperation with the servo motor, so as to ensure that the pole piece B can be reliably clamped and fixed under the condition of unstable negative pressure.

[0084] In one of the embodiments, the thickness of the pole piece is not higher than the length of the soft hair, so as to ensure that the soft hair brush can achieve comprehensive cleaning and dust removal effect on the single side wall of the pole piece B.

[0085] It can be understood that, as shown in Figure 9 when the thickness of the pole piece is less than the length of the soft hair brush, the utilization rate of the soft hair brush is low. Therefore, in a preferred embodiment, the thickness of the pole piece is equal to the length of the soft hair brush, so as to sufficiently improve the utilization rate of the soft hair brush.

[0086] As shown in Figures 2-3As shown, in one embodiment, the dust removal device 10 comprises a rack 100, a workbench 200, a jacking mechanism 300, a tablet pressing mechanism 400, a first opening and closing dust removal mechanism 510, a second opening and closing dust removal mechanism 520, a first negative pressure extraction assembly 600, and a second negative pressure extraction assembly. The workbench 200 is arranged on the rack 100, the jacking mechanism 300 is arranged below the workbench 200 and connected to the rack 100, the tablet pressing mechanism 400 is arranged above the workbench 200 and opposite to the jacking mechanism 300, and the first opening and closing dust removal mechanism 510 and the second opening and closing dust removal mechanism 520 are movably arranged on the rack 100. When the first opening and closing dust removal mechanism 510 and the second opening and closing dust removal mechanism 520 abut each other, a relatively sealed blowing-suction-sweeping processing cavity 700 is formed, and when they are relatively far away, the blowing-suction-sweeping processing cavity 700 is opened. The first opening and closing dust removal mechanism 510 and the second opening and closing dust removal mechanism 520 wrap the pole piece B in the relatively sealed blowing-suction-sweeping processing cavity 700, and then perform ion blowing operation, negative pressure vacuum operation and cleaning operation, so as to achieve the effect of fully removing dust from the four side walls of the pole piece B.

[0087] As Figures 3-5As shown, in one of the embodiments, the first opening and closing dust removal mechanism 510 includes a first driver 511, a first frame 512, a first brush assembly 513, a second brush assembly 514, a third brush assembly 515, a first ion inclined air knife 516, a second ion inclined air knife 517, and a third ion inclined air knife 518. Since a first semi-open cavity 5121 is formed in the first frame 512, the first frame 512 is movably arranged on the rack 100 of the dust removal equipment 10 and connected with the driving end of the first driver 511. The first driver 511 is arranged on the rack 100, so that the first frame 512 can move back and forth along the rack 100 under the action of the first driver 511, so that the first frame 512 cooperates with the second frame 522 to form a relatively closed blowing-suction-sweeping processing cavity 700. The first brush assembly 513 is movably arranged on the first side wall of the first semi-open cavity 5121, the second brush assembly 514 is movably arranged on the second side wall of the second semi-open cavity 5221, and the third brush assembly 515 is movably arranged on the third side wall of the third semi-open cavity. The first brush assembly 513, the second brush assembly 514, and the third brush assembly 515 are arranged corresponding to the first side wall, the second side wall, and the third side wall of the pole piece B, so that the first brush assembly 513, the second brush assembly 514, and the third brush assembly 515 can sweep the first side wall, the second side wall, and the third side wall of the pole piece B back and forth, so as to effectively sweep off the dust with strong adhesion on the side wall of the pole piece B. In particular, the first ion inclined air knife 516 is arranged above the first brush assembly 513, the second ion inclined air knife 517 is arranged above the second brush assembly 514, and the third ion inclined air knife 518 is arranged above the third brush assembly 515, so that the first ion inclined air knife 516, the second ion inclined air knife 517, and the third ion inclined air knife 518 can better blow off the dust on the first side wall, the second side wall, and the third side wall of the pole piece B, as well as most of the dust on the first brush assembly 513, the second brush assembly 514, and the third brush assembly 515, thereby ensuring that the bristles of the first brush assembly 513, the second brush assembly 514, and the third brush assembly 515 still have good cleaning effect after a long time of use. Not only does this prolong the replacement cycle of the first brush assembly 513, the second brush assembly 514, and the third brush assembly 515, but also reduces the replacement frequency of the first brush assembly 513, the second brush assembly 514, and the third brush assembly 515, effectively reducing the dust removal cost of the pole piece B.

[0088] As Figure 3 and Figure 6As shown, in one of the embodiments, the second opening and closing dust removal mechanism 520 comprises a second driver 521, a second frame body 522, a fourth brush assembly 523 and a fourth ion inclined air knife 524; the second frame body 522 is arranged opposite to the first frame body 512, and the second frame body 522 is movably connected to the rack 100 of the dust removal equipment 10 and connected to the driving end of the second driver 521; the second driver 521 is arranged on the rack 100, so that the second frame body 522 can move back and forth along the rack 100 under the action of the second driver 521, thereby ensuring that the first frame body 512 and the second frame body 522 can be used in cooperation to close to form a relatively closed blowing-suction-sweeping processing cavity 700; the second frame body 522 forms a second half-open cavity 5221, the fourth brush assembly 523 is movably arranged on the first side wall of the second half-open cavity 5221, and the fourth brush assembly 523 is arranged corresponding to the fourth side wall of the pole piece B, so that the first brush assembly 513, the second brush assembly 514, the third brush assembly 515 and the fourth brush assembly 523 can be arranged one by one corresponding to the four side walls of the pole piece B, so as to realize the comprehensive cleaning and dust removal operation of the four side walls of the pole piece B, and also ensure that the first ion inclined air knife 516, the second ion inclined air knife 517, the third ion inclined air knife 518 and the fourth ion inclined air knife 524 can better blow off the dust on the four side walls of the pole piece B and the dust on the first brush assembly 513, the second brush assembly 514, the third brush assembly 515 and the fourth brush assembly 523, thereby reducing the replacement cycle and frequency of the first brush assembly 513, the second brush assembly 514, the third brush assembly 515 and the fourth brush assembly 523, and further reducing the dust removal cost of the pole piece B.

[0089] As shown in Figure 5 , Figure 6 and Figure 9 , in one of the embodiments, the first brush assembly 513 comprises a first soft brush 5131, a first cleaning arm 5132 and a third driver 5133; the first cleaning arm 5132 is movably arranged on the first side wall of the first half-open cavity 5121, and the first end of the first cleaning arm 5132 is connected to the driving end of the second driver 521; the second end of the first cleaning arm 5132 is connected to the first soft brush 5131, so that the first cleaning arm 5132 can drive the first soft brush 5131 to clean the side wall of the pole piece B back and forth under the action of the second driver 521, thereby realizing the movable cleaning arrangement of the first brush assembly 513.

[0090] In one of the embodiments, the first cleaning arm 5132 comprises a first horizontal sliding piece 5132a, a first vertical connecting piece 5132b and a first horizontal adjusting piece 5132c, the first horizontal sliding piece 5132a is movably arranged in the first frame body 512, and the first horizontal sliding piece 5132a is connected with the driving end of the third driver 5133, so that the third driver 5133 can drive the first horizontal sliding piece 5132a to move back and forth in the first frame body 512; since the first horizontal sliding piece 5132a is connected with the first horizontal adjusting piece 5132c through the first vertical connecting piece 5132b and is jointly connected to form a Z-shaped structure, the first horizontal adjusting piece 5132c is connected with the first soft brush 5131, when the third driver 5133 drives the first horizontal sliding piece 5132a, the first vertical connecting piece 5132b, the first horizontal adjusting piece 5132c and the first soft brush 5131 move together to realize the back and forth cleaning operation of the pole piece B. Further, since the first horizontal sliding piece 5132a is connected with the first horizontal adjusting piece 5132c through the first vertical connecting piece 5132b and is jointly connected to form a Z-shaped structure, the horizontal distribution of the first cleaning arm 5132 in the first frame body 512 is shortened, the compactness of the Z-shaped first cleaning arm 5132 connected in the first semi-open cavity 5121 is improved, thereby improving the utilization space of the first semi-open cavity 5121 to better adapt to the cleaning and dust removal needs of the pole piece B of larger specifications.

[0091] Further, the first horizontal adjusting piece 5132c facilitates the user to adjust the position of the first soft brush 5131, thereby improving the adaptability of the dust removal equipment 10 to pole pieces B of different specifications.

[0092] As shown in the drawings, Figure 9 In one of the embodiments, the first brush assembly 513 further comprises a first adjusting piece 5134 and a first limiting piece 5135, the first vertical connecting piece 5132b is slidably arranged in the first horizontal sliding piece 5132a, the first limiting piece 5135 is arranged at one end of the first horizontal sliding piece 5132a away from the driving end of the third driver 5133, and the first limiting piece 5135 is used to prevent the first vertical connecting piece 5132b from falling off; the first adjusting piece 5134 is movably arranged between the first limiting piece 5135 and the first vertical connecting piece 5132b, and the first adjusting piece 5134 is used to adjust the position of the first soft brush 5131 in the first horizontal sliding piece 5132a, thereby realizing the adjustment of the cleaning position of the pole piece B, and improving the adaptability of the dust removal equipment 10 to pole pieces B of different specifications; the first limiting piece 5135 can prevent the first vertical connecting piece 5132b from falling off easily during the cleaning process, thereby ensuring the reliability of the cleaning of the first soft brush 5131.

[0093] As shown in the drawings, Figure 5As shown, in one of the embodiments, the first horizontal adjusting piece 5132c is formed with a fine-tuning waist-shaped groove, and the extension direction of the fine-tuning waist-shaped groove is consistent with the horizontal direction of the first horizontal adjusting piece 5132c, so as to realize fine adjustment of the cleaning position of the pole piece B, thereby ensuring accurate positioning of the first soft brush 5131 and the cleaning position of the pole piece B, and further improving the adaptability of the dust removal equipment 10 to pole pieces B of different specifications.

[0094] As shown, Figure 9 As shown, in one of the embodiments, the first adjusting piece 5134 is an adjusting screw, the first limiting piece 5135 is provided with a first through hole, the first vertical connecting piece 5132b is provided with a first adjusting screw hole and a first sliding hole, and the first vertical connecting piece 5132b is slidingly arranged in the first horizontal sliding piece 5132a through the first sliding hole, so as to realize sliding arrangement of the first vertical connecting piece 5132b in the first horizontal sliding piece 5132a. The adjusting screw passes through the first through hole and the first adjusting screw hole in sequence and is screwed with the side wall of the first adjusting screw hole. When the user needs to adjust the cleaning position, the adjusting screw can be manually rotated, thereby driving the first vertical connecting piece 5132b to move, so as to realize adjustment of the cleaning position of the first soft brush 5131.

[0095] As shown, Figure 9 As shown, in one of the embodiments, the first brush assembly 513 further comprises a first nut fastener 5136 arranged at the end of the first adjusting piece 5134 away from the third driver 5133, so that the added first nut fastener 5136 can realize limiting and fixing of the first limiting piece 5135 and the first vertical connecting piece 5132b, thereby further improving the cleaning reliability of the first brush assembly 513.

[0096] In one of the embodiments, the first soft brush 5131 comprises a first mounting plate and a plurality of soft hairs. The first mounting plate is detachably connected with the first horizontal adjusting piece 5132c, and each soft hair is arranged on the side of the first mounting plate facing the pole piece B, so as to realize detachable arrangement of the first soft brush 5131 and the first horizontal adjusting piece 5132c, thereby facilitating the user to replace the first soft brush 5131, and further improving the adaptability of the first soft brush 5131. Specifically, the detachable connection between the first mounting plate and the first horizontal adjusting piece 5132c can be screw connection.

[0097] In one of the embodiments, each bristle comprises a connected elastic hard part and a bristle cleaning part, which on one hand ensures that the elastic hard part is not prone to deformation in long-time cleaning, and on the other hand ensures that the elastic hard part will automatically restore its shape when not in contact with the pole piece B, so as to enter the cleaning return stroke, so that the bristle cleaning part quickly contacts the pole piece B, thereby better ensuring the back-and-forth cleaning effect of the bristle, and also ensuring that the bristle can maintain a good structure form in long-time use, thereby ensuring the long-time cleaning and dust removal effect of the bristle.

[0098] It should be noted that the movable arrangement of the first horizontal sliding member 5132a and the first side wall of the first semi-open cavity 5121, the movable arrangement of the first frame body 512 and the second frame body 522 in the rack 100 of the dust removal equipment 10 belong to the prior art, and therefore, detailed description is not given in the present disclosure.

[0099] Similarly, the second brush assembly 514, the third brush assembly 515, and the fourth brush assembly 523 all have the same structure as the first brush assembly 513, so as to realize the movable cleaning arrangement of the second brush assembly 514, the third brush assembly 515, and the fourth brush assembly 523.

[0100] As shown in Figure 5 and Figure 8 In one of the embodiments, the side walls of the first semi-open cavity 5121 and / or the second semi-open cavity 5221 are formed with a lifting entry avoiding slot and a pressing piece extension avoiding slot, and the lifting entry avoiding slot and the pressing piece extension avoiding slot are oppositely arranged, so that the lifting entry avoiding slot can provide a containing space for the lifting rod 320, and the pressing piece extension avoiding slot can provide a containing space for the connecting rod, so as to ensure that when the first frame body 512 and the second frame body 522 are closed, the lifting rod 320 and the connecting rod can enter the blowing-sucking-cleaning processing cavity 700 from the lifting entry avoiding slot and the pressing piece extension avoiding slot respectively, so as to realize the clamping and fixing of the pole piece B.

[0101] As shown in Figure 6 and Figure 8As shown, in one of the embodiments, the first half-open cavity 5121 is formed with a first opening towards the second half-open cavity 5221, one side of the second half-open cavity 5221 is formed with a second opening towards the first half-open cavity 5121, the upper side wall of the first opening is recessed to form a first pressing piece extending half-open slot, the lower side wall of the first opening is correspondingly recessed to form a first jacking entering half-open slot 5121a, the upper side wall of the second opening is correspondingly recessed to form a second pressing piece extending half-open slot 5221a, and the lower side wall of the second opening is correspondingly recessed to form a second jacking entering half-open slot 5221b. When the first frame 512 and the second frame 522 are closed, the first pressing piece extending half-open slot and the second pressing piece extending half-open slot 5221a can be closed to form a pressing piece extending avoidance slot, and the first jacking entering half-open slot 5121a and the second jacking entering half-open slot 5221b can be closed to form a jacking entering avoidance slot. The jacking entering avoidance slot and the pressing piece extending avoidance slot can well accommodate the jacking rod 320 and the connecting rod, effectively reducing the collision probability of the jacking rod 320 and the connecting rod with the first frame 512 and the second frame 522 when closed, thereby improving the service life of the jacking rod 320 and the connecting rod.

[0102] In order to ensure that the first frame 512 and the second frame 522 can form a relatively sealed blowing-suction-sweeping treatment cavity 700 when closed, as shown, Figure 8 As shown, in one of the embodiments, the first frame 512 further comprises a first sealing member 910 arranged on the four surrounding side walls of the first opening, and the second frame 522 further comprises a second sealing member 920 arranged on the four surrounding side walls of the second opening. The added first sealing member 910 and second sealing member 920 can improve the sealing performance of the blowing-suction-sweeping treatment cavity 700, effectively avoiding the phenomenon of large-area dust escaping.

[0103] It should be noted that although the added first sealing member 910 and second sealing member 920 can well improve the sealing performance of the blowing-suction-sweeping treatment cavity 700, it leads to the problem that it is difficult to open the first frame 512 and the second frame 522 after dust removal. Therefore, in one of the embodiments, the first jacking entering half-open slot 5121a is not provided with the first sealing member 910, and the second jacking entering half-open slot 5221b is not provided with the second sealing member 920. In this way, the negative pressure of the blowing-suction-sweeping treatment cavity 700 after dust removal is reduced, effectively improving the problem that it is difficult to open the first frame 512 and the second frame 522 after dust removal.

[0104] It can be understood that although the first seal 910 and the second seal 920 are not arranged in the first lifting entry half-slot 5121a and the second lifting entry half-slot 5221b, the problem that the first frame 512 and the second frame 522 are difficult to open after dust removal is improved to a certain extent, but the effect is not very ideal. Therefore, in one of the embodiments, the first lifting entry half-slot 5121a is not arranged with the first seal 910 on the side wall of the side where the first opening is located, or the second lifting entry half-slot 5221b is not arranged with the second seal 920 on the side wall of the side where the second opening is located, please refer to Figure 8 , so as to ensure that the first frame 512 and the second frame 522 are more appropriate in sealing the blow-suction-sweep processing cavity 700 formed when closed, and facilitate the opening of the blow-suction-sweep processing cavity 700 after dust removal; also maximally reduce the problem of dust escaping; also ensure that the pole piece B will not be easily bent and deformed due to complete sealing during the dust removal process.

[0105] In one of the embodiments, the size of the lifting entry avoidance slot is greater than the size of the lifting rod 320, the area of the bearing plate is less than the area of the pole piece B, and the area of the pole piece B is greater than the area of the lifting entry avoidance slot. It can be understood that since the size of the lifting entry avoidance slot is greater than the size of the lifting rod 320, a certain gap is formed when the lifting rod 320 is located in the lifting entry avoidance slot, so as to solve the problem that the first frame 512 and the second frame 522 are difficult to open due to strong sealing of the blow-suction-sweep processing cavity 700; and since the area of the bearing plate is less than the area of the pole piece B, and the area of the pole piece B is greater than the area of the lifting entry avoidance slot, the pole piece B can fully shield the lifting entry avoidance slot, effectively reducing the problem of large-area dust escaping from the lifting entry avoidance slot, especially when the bearing plate and the pressing plate each occupy 1 / 3-2 / 3 of the overall size of the pole piece B, it also ensures that the four side walls of the pole piece B are completely exposed, so as to facilitate cleaning and dust removal; also maximally ensures the reliable clamping force of the bearing plate on the pole piece B, effectively avoids the problems that the pole piece B is easily deformed or indented under the conditions of negative pressure, blowing ion wind and cleaning, so as to better ensure the product quality and dust removal effect of the single pole piece A; also solves the problem that the first frame 512 and the second frame 522 are difficult to open after dust removal due to strong sealing of the blow-suction-sweep processing cavity 700; also effectively reduces the problem of large-area dust escaping from the lifting entry avoidance slot.

[0106] As shown in Figure 2 and Figure 10 , in one of the embodiments, the dust removal equipment 10 further comprises a protective cover 800, the protective cover 800 is arranged above the rack 100, and forms a relatively closed outer cavity 810 with the workbench 200, one side of the outer cavity 810 forms a material taking operation port 811, and the first frame 512 and the second frame 522 are relatively movably arranged in the outer cavity 810.

[0107] It can be understood that the gap between the blow-suck-sweep processing cavity 700 and the jacking rod 320 when closed will cause a small amount of dust to escape. Therefore, in the present disclosure, by relatively movably arranging the first frame 512 and the second frame 522 in the outer cavity 810, the blow-suck-sweep processing cavity 700 formed when the first frame 512 and the second frame 522 are closed is located in the relatively closed outer cavity 810, that is, a "cavity-in-cavity" structure is formed, which prolongs the path of dust escaping from the blow-suck-sweep processing cavity 700, effectively reducing the amount of dust escaping from the blow-suck-sweep processing cavity 700 to the workshop.

[0108] It can be understood that if the material taking operation port 811 and the first opening and the second opening are not properly arranged, the amount of dust escaping from the blow-suck-sweep processing cavity 700 to the workshop will increase, which will seriously affect the cleanliness of the workshop. Therefore, in one embodiment, the first opening of the first frame 512, the second opening of the second frame 522, and the material taking operation port 811 are arranged in a straight line, the first opening of the first frame 512 is arranged to face away from the material taking operation port 811, and the first opening and the second opening are arranged opposite to each other; or the second opening of the second frame 522 is arranged to face away from the material taking operation port 811, and the first opening and the second opening are arranged opposite to each other. In this way, when the first frame 512 and the second frame 522 are closed for dust removal, the dust jacked into the avoidance slot will first enter the outer cavity 810, and then escape from the material taking operation port 811 of the outer cavity 810. In this way, on the one hand, the amount of dust escaping is reduced, and on the other hand, a delay operation time is provided for the negative pressure vacuum operation, especially in combination with the 3s-5s delayed closing operation of the negative pressure vacuum operation, so that the delayed closing negative pressure vacuum operation can more comprehensively extract the dust in the magazine, the first frame 512, the second frame 522, and the outer cavity 810, to avoid the secondary pollution of the dust on the pole piece B after dust removal, and also ensure the sealing performance of the first frame 512 and the second frame 522 in the next closing, to ensure that the blow-suck-sweep processing cavity 700 can still maintain relative sealing performance when the first frame 512 and the second frame 522 are used for multiple cycles, and better ensure the dust removal effect of the dust removal equipment 10 after multiple cycles. It also effectively avoids the dust from escaping from the jacking into the avoidance slot to the outside, thereby better ensuring the cleanliness of the production workshop.

[0109] As Figure 5 and Figure 3As shown, in one embodiment, the first frame 512 is further formed with at least one first suction port 5122, each first suction port 5122 being arranged adjacent to a corner of the first frame 512; the second frame 522 is further formed with at least one second suction port, each second suction port being arranged adjacent to a corner of the second frame 522; the first tablet insertion half-slot and the first jacking half-slot 5121a are both recessed in the middle of the first opening; the second tablet insertion half-slot 5221a and the second jacking half-slot 5221b are both recessed in the middle of the second opening; so that when the first frame 512 and the second frame 522 are closed, the pole piece B can be located in the middle of the blowing-suction-sweeping treatment cavity 700, ensuring that the pole piece B is subjected to a relatively uniform force in the treatment cavity, effectively avoiding the problem that the pole piece B is easily deformed when the negative pressure is relatively strong; in combination with the first suction port 5122 being arranged adjacent to a corner of the first frame 512 and the second suction port being arranged adjacent to a corner of the first frame 512, the removed dust can flow well from the middle of the blowing-suction-sweeping treatment cavity 700 to the corners, not only effectively reducing the amount of dust escaping from the jacking half-slot, but also ensuring that the first negative pressure extraction assembly 600 and the second negative pressure extraction assembly can fully extract the dust in the blowing-suction-sweeping treatment cavity 700, thereby well ensuring the cleanliness of the blowing-suction-sweeping treatment cavity 700.

[0110] In one embodiment, the first frame 512 and the second frame 522 are both made of sheet metal.

[0111] In one embodiment, the dust removal equipment 10 further comprises a first negative pressure extraction assembly 600 and a second negative pressure extraction assembly, both of which are arranged below the rack 100; the first negative pressure extraction assembly 600 comprises a first air extractor, a first filter and a first collection bin, the first air extractor being in communication with the first collection bin through the first filter, and the hose of the first air extractor being in communication with the first suction port 5122; the second negative pressure extraction assembly comprises a second air extractor, a second filter and a second collection bin, the second air extractor being in communication with the second collection bin through the second filter, and the hose of the second air extractor being in communication with the second suction port, so as to realize the communication between the first negative pressure extraction assembly 600 and the first frame 512 and the communication between the second negative pressure extraction assembly and the second frame.

[0112] In a more preferred embodiment, the number of the first suction port 5122, the second suction port, the first negative pressure extraction assembly 600 and the second negative pressure extraction assembly is two.

[0113] In one of the embodiments, the second ion tilting air knife 517 and the fourth ion tilting air knife 524 are located above the first ion tilting air knife 516 and the third ion tilting air knife 518, so that the second ion tilting air knife 517 and the fourth ion tilting air knife 524 can form a group of ion air, and the first ion tilting air knife 516 and the third ion tilting air knife 518 can form another group of ion air, so as to form different levels of ion air in the blowing-suction-sweeping processing cavity 700, so as to better blow off the dust on the side walls of the pole piece B.

[0114] In one of the embodiments, the air outlet directions of the first ion tilting air knife 516, the second ion tilting air knife 517, the third ion tilting air knife 518 and the fourth ion tilting air knife 524 are all downwardly inclined, so as to ensure that the downwardly inclined ion air can better blow off the dust in the recessed parts around the pole piece B. Specifically, in one of the embodiments, the downwardly inclined angle is 20°-50°.

[0115] In one of the embodiments, by separately controlling the movement of the first soft brush 5131, the second soft brush, the third soft brush and the fourth soft brush, the cleaning strength and the cleaning range of each side wall of the pole piece B can be better controlled, so as to achieve a comprehensive cleaning and dust removal effect on the side walls of the pole piece B.

[0116] It should be noted that since the lengths of the side walls around the pole piece B are not equal, and one of the side walls of the pole piece B is provided with a tab part, i.e., the tab part is protrudingly arranged on one side of the pole piece B, if the end adjacent to the tab part is taken as the cleaning starting end of the soft brush, it is easy to cause the tab part to be broken or damaged due to the relatively large and unstable cleaning strength of the soft brush at the start. Therefore, in the present disclosure, when cleaning the side wall of the pole piece B provided with the tab part, the end away from the tab part is taken as the cleaning starting end of the soft brush, so that the path of the cleaning starting end of the soft brush is extended, so as to ensure that the cleaning strength of the soft brush when entering the tab part for cleaning is relatively stable, effectively avoiding the phenomenon that the tab part is easily broken or damaged, thereby better ensuring the dust removal effect and product quality of the single pole piece A.

Specifically, the fourth driver 310 is a servo motor.

[0119] In one embodiment, the tablet pressing mechanism 400 comprises a fifth driver, a connecting seat, a connecting rod and a pressing plate, the connecting seat is located above the movable slot and is connected to the rack 100, the connecting rod is movably arranged in the connecting seat, and the first end of the connecting rod towards the jacking rod 320 is connected with the pressing plate, the second end of the connecting rod is connected with the driving end of the fifth driver, and the fifth driver is arranged on the rack 100, so that the pressing plate can realize the lifting of the pressing plate under the action of the fifth driver, so as to ensure the clamping and fixing of the pole piece B. Specifically, the fifth driver is a Yadea brand cylinder.

[0120] In one embodiment, the dust removal device 10 further comprises a limiting piece, the limiting piece is arranged on the workbench 200, and the limiting piece is used for limiting and fixing the clip. The limiting piece and the connection between the limiting piece and the workbench 200 are both prior art, so they are not described in detail in the present disclosure.
