DETAILED DESCRIPTION
[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0023] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.
[0024] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.
[0025] like Figure 1As shown, the dust removal device according to the embodiment of the present application includes a fixed seat, a dust suction component 20 and a blowing component 30. The fixed seat is provided with a placement position 11, and the placement position 11 is used to place the items to be cleaned. The dust suction component 20 and the blowing component 30 are respectively arranged on opposite sides of the placement position 11 along the first direction. The dust suction component 20 includes an air suction machine, and the air suction machine includes a dust suction port 21. The blowing component 30 includes an air blower, and the air blower includes a blowing port 31. The dust suction port 21 and the blowing port 31 are arranged relative to each other.
[0026] Specifically, the placement position 11 is used to place the items to be cleaned. The dust collection assembly 20 and the air blowing assembly 30 are respectively arranged on opposite sides of the placement position 11 along the first direction. The air blowing assembly 30 can spray an airflow toward the items to be cleaned. The airflow will blow away the dust attached to the items to be cleaned, and the dust collection assembly 20 will absorb the airflow with dust, reducing the possibility of dust re-attachment, thereby utilizing the negative pressure formed to clean the dust on the items to be cleaned. The suction machine provides power for the suction airflow, and the air blower provides power for the blowout airflow. The dust collection port 21 and the air blowing port 31 are arranged relative to each other. The air blowing port 31 is conducive to blowing away the dust. There is a pressure difference between the dust collection port 21 and the area of the items to be cleaned, which is conducive to forming a negative pressure environment around the items to be cleaned, driving the dust into the dust collection port 21 and sucking the dust cleanly. In this way, the dust removal effect can be enhanced, the items to be cleaned can be prevented from being scratched or damaged, and the risk of dust re-attachment can be eliminated.
[0027] In addition, the first direction may be the length direction of the object to be cleaned, or the width direction of the object to be cleaned, and the size of the placement position 11 may be set as needed to match the size of the object to be cleaned.
[0028] It should be noted that the number of the dust suction ports 21 is one or more, and the number of the air blowing ports 31 is one or more, which can be set as needed.
[0029] In a specific embodiment, the part to be cleaned is the pole piece 2 .
[0030] In addition, the gas source can be air or nitrogen. When the gas source is nitrogen, it can reduce the overall cost of the dust collection component 20 and the blowing component 30, increase the negative pressure extraction capacity of the dust collection component 20 to above -95kpa, enhance the first dust collection effect of the parts to be cleaned, and shorten the process cycle.
[0031] According to the dust removal device of the embodiment of the present application, the dust suction component 20 and the blowing component 30 are used to form airflow negative pressure dust suction. After the blowing component 30 blows up the dust, it is mixed in the airflow and sucked away together by the dust suction component 20, thereby achieving the dust removal effect on the cleaning parts and avoiding the risk of powder and material falling off caused by scratches on the cleaning parts.
[0032] like Figure 1As shown, according to the dust removal device of an embodiment of the present application, an air guide groove 12 is provided at the bottom of the placement position 11, and the air guide groove 12 extends along the first direction.
[0033] In detail, an air guide groove 12 is provided at the bottom of the placement position 11. When the part to be cleaned is located in the placement position 11, the air guide groove 12 is located below the part to be cleaned, and the air flow blown out by the blowing component 30 can pass under the part to be cleaned to clean and remove dust on the lower side. After one side of the part to be cleaned is cleaned, the other side of the part to be cleaned can be cleaned by negative pressure blowing. The added air guide groove 12 is used to increase the time for dust removal on one side of the part to be cleaned. For example, when the single-sided cleaning time requires 15S, the lower side is cleaned for 15S when the upper side is cleaned. After turning over, both the upper and lower sides are cleaned for 15S. Compared with the single-sided cleaning of 15S without the air guide groove 12, the single-sided cleaning time is extended to 30S after the air guide groove 12 is added. In this way, the single-sided cleaning time can be adjusted according to different parts to be cleaned while ensuring the cleaning degree, thereby improving the cleaning efficiency of the dust removal device and the cleaning effect of the dust removal device.
[0034] In some embodiments, a plurality of limiting members are provided on the fixing seat, and the plurality of limiting members are spaced apart along the circumferential direction of the fixing seat, and the plurality of limiting members jointly define a placement position 11 .
[0035] In detail, the fixing seat is provided with a plurality of limiting members (such as Figure 1 As shown, the limiting members are divided into a first limiting member 13 and a second limiting member 14) and a plurality of limiting members jointly define a placement position 11, and the limiting members are used to limit the position of the parts to be cleaned, thereby limiting the degree of freedom of the parts to be cleaned, so that the parts to be cleaned can maintain their original position without shifting when dust is blown by a strong airflow, thereby avoiding affecting the dust removal effect.
[0036] Among them, the number of limiting parts can be set as needed, for example, three, four, five, six or seven, etc. Multiple limiting parts are set at intervals, which can reduce the contact area with the parts to be cleaned, facilitate the airflow to flow out from the intervals between the limiting parts, and facilitate the dust to be separated from the parts to be cleaned with the airflow.
[0037] In some embodiments, there are multiple air guide grooves 12, and the multiple air guide grooves 12 are arranged at intervals along the second direction. Two adjacent limiting members define a spacing position, and the portion of the air guide groove 12 opposite to the spacing position extends to pass through the spacing position, and the portion of the air guide groove 12 opposite to the limiting member is spaced from the limiting member, wherein the second direction is perpendicular to the first direction.
[0038] To elaborate, there are multiple air guide grooves 12, and the multiple air guide grooves 12 are arranged at intervals along the second direction. Two adjacent limiting members define a spacing position to facilitate the passage of airflow, thereby improving the dust removal effect of the parts to be cleaned and avoiding blocking the airflow. The part of the air guide groove 12 opposite to the spacing position extends to penetrate the spacing position, which is beneficial to the flow of airflow and improves the cleaning effect of the parts to be cleaned. The part of the air guide groove 12 opposite to the limiting member is spaced from the limiting member. In this way, the connection strength between the limiting member and the fixing seat can be guaranteed, thereby improving the service life of the dust blowing device.
[0039] Among them, the second direction is perpendicular to the first direction, which can simplify the structural setting so that the air guide groove 12 can extend along the width direction or length direction of the part to be cleaned. When the length of the part to be cleaned is greater than the width, it is preferred to set the second direction to extend along the length direction of the part to be cleaned.
[0040] like Figure 1 As shown, in some embodiments, multiple limiting members are divided into a first limiting member 13 and a second limiting member 14, the number of the first limiting members 13 is four, and the four first limiting members 13 are respectively arranged at the four corner ends of the placement position 11, and the first limiting member 13 includes a first sub-limiting portion 131 and a second sub-limiting portion 132 that are interconnected, the first sub-limiting portion 131 is used to abut against one side edge of the front cleaning member, and the second sub-limiting portion 132 is used to abut against the other side edge of the front cleaning member, and the second limiting member 14 is located between two adjacent first limiting members 13.
[0041] Specifically, the multiple limiting members are divided into a first limiting member 13 and a second limiting member 14. The number of the first limiting members 13 is four, and the four first limiting members 13 are respectively arranged at the four corner ends of the placement position 11. Therefore, when the part to be cleaned is placed at the placement position 11, the four first limiting members 13 are used to limit and fix the four corner ends of the part to be cleaned, thereby limiting the degree of freedom of the part to be cleaned, improving the positioning accuracy of the part to be cleaned, and reducing the difficulty of positioning.
[0042] Secondly, the first sub-limiting portion 131 is used to abut against one side edge of the cleaning part, and the second sub-limiting portion 132 is used to abut against the other side edge of the cleaning part, thereby improving the limiting accuracy of the cleaning part, avoiding displacement and misplacement of the cleaning part, and simplifying the difficulty of placing the cleaning part in the correct position.
[0043] In addition, the second limiting member 14 is arranged between adjacent first limiting members 13, which can play an auxiliary limiting and positioning role for the cleaning member. Since the cleaning member is relatively thin, it can avoid damage to the cleaning member when it is larger in size and is restricted by the first limiting member 13 alone.
[0044] In some embodiments, the second limiting member 14 is in the shape of a flat plate.
[0045] In detail, the second limiting member 14 is in the shape of a flat plate, which can simplify the shape and structure of the second limiting member 14, thereby facilitating processing and reducing the overall cost of the dust removal device.
[0046] like Figure 1 As shown, according to the dust removal device of the embodiment of the present application, a sunken picking groove 15 is provided on the fixing seat, and part of the picking groove 15 is located in the placement position 11.
[0047] Specifically, a sunken picking groove 15 is provided on the fixing seat, and part of the picking groove 15 is located in the placement position 11. This setting is to avoid the operator's hands, making it convenient for the operator to extend his hands below to take out the parts to be cleaned, turn them over, or directly transfer them to the next workstation.
[0048] It should be noted that the area and depth of the picking slot 15 can be set as needed to facilitate users of different body shapes and sizes to reach in.
[0049] like Figure 1 As shown, in some embodiments, the area of the portion of the picking slot 15 located inside the placement position 11 is smaller than the area of the portion located outside the placement position 11 .
[0050] In detail, the area of the part of the picking groove 15 located inside the placement position 11 is smaller than the area of the part located outside the placement position 11. On the basis of facilitating picking up, it can reduce the accumulation of dust in the picking groove 15 and avoid the dust accumulated in the picking groove 15 from being adsorbed onto the part to be cleaned for the second time.
[0051] According to the dust removal device of the embodiment of the present application, a filter 22 is provided at the dust suction port 21. The filter 22 seals the dust suction port 21 and is provided with a plurality of arrays of ventilation holes. Thus, the filter 22 can filter out large foreign matter that is attracted, preventing it from being sucked in and damaging the machine. For example, the foreign matter could be a piece of pole piece 2 or something else that has been dragged along.
[0052] like Figure 1 As shown, according to the dust removal device of the embodiment of the present application, the number of the dust suction port 21 is one, the number of the air blowing ports 31 is multiple, and the multiple air blowing ports 31 are arranged at intervals and are all arranged opposite to the dust suction port 21.
[0053] It can be understood that setting up multiple blowing ports 31 can help to gather the airflow and enhance the cleaning force on the parts to be cleaned, while the number of suction ports 21 is only one, which can retract most of the airflow as much as possible, thereby absorbing most of the dust and preventing it from falling back onto the parts to be cleaned for a second time.
[0054] In a specific embodiment, the part to be cleaned is the electrode 2, and the use of pulsed compressed airflow (0.5kPa) can enhance the dust removal effect of the electrode 2, avoid damage to the electrode 2, and eliminate the risk of dust re-attachment to the electrode 2. (Wherein, pulsed compressed airflow dust cleaning is to enhance the dust removal effect of the electrode 2 in stages by using compressed air).
[0055] Among them, one treatment process is: the air blowing port 31 sprays 5 times, the air blowing positive pressure is 0.5Kpa, the dust suction port 21 negative pressure is -70kpa, and the total dust removal time is 15s.
[0056] Specifically:
[0057] Before dust removal, clean the workbench and use alcohol to clean the air guide groove 12 and the first limiter 13, which are areas prone to dirt accumulation. Open the dust suction port 21 and start the air blowing port 31 to test whether the pulse blowing can be normal for 5 times.
[0058] Prepare the pole piece 2 and place the pole piece 2 in the fixed frame;
[0059] Pole piece 2 dust removal, the air outlet 31 pulses out a 0.5kPa airflow, which lifts the dust particles on the surface of the pole piece 2 and transfers them to the -70kPa dust suction port 21 along with the airflow. Due to the pressure difference between the inside of the dust suction port 21 and the pole piece 2 area, the dust particles are driven to flow into the dust suction port 21;
[0060] Dust removal cycle: according to the dust cleanliness of the pole piece 2, the picking tank 15 turns the pole piece 2 over, blows air to remove dust again, and the positive and negative pressure cycles once;
[0061] Stop dust removal and blowing to pick up the electrode 2.
[0062] In comparison with the principle of traditional brush cleaning dust, in this embodiment, the staged pulse positive pressure airflow is used to enhance the ability of removing dust attached to the electrode 2, and the time taken by the ordinary brush to clean the electrode 2 is optimized from 50 seconds to 15 seconds, the injection time is shortened by 35 seconds, and the dust removal efficiency is improved by 70%.
[0063] The dust removal device of the embodiment of the present application is suitable for most small soft-pack battery cells, high group margin (more than 90%), flat battery cells, and small-sized pole pieces 2, etc.
[0064] like Figure 1 As shown, in a specific embodiment, the inner dimensions of the placement position 11 are both 88 mm in length in the first direction and 88 mm in width in the second direction, which can accommodate a 78.0±2 mm (L) * 81.0±2 mm (W) positive electrode sheet and a 82.0±2 mm (L) * 85.0±2 mm (W) negative electrode sheet.
