[0002] In the lithium battery, photovoltaic, medical, FPCB and other industries, coil materials are needed. When the coil materials are die-cut, stamped and other operations are performed on them, dust will be generated at the cutting position, which will lead to foreign matter on the surface, edge or opening hole wall of the coil materials. If the dust is not effectively cleaned, the terminal products of the coil materials may have poor functional quality during application, resulting in an increase in the defective rate of the coil materials.
[0003] At present, some industries still use traditional rubber roller dust removal, which uses the adhesive force of the rubber roller to clean dust and other foreign matter on the roll material. The cleaning effect is poor for the edges of the roll material or positions with height differences. In addition, after a period of use, the rubber roller will age and the adhesive force will decay, and the cleaning rate of foreign matter is extremely low, resulting in a high defective rate of roll material products.

[0036] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:
[0037] Reference Figures 1 to 3 , is a multi-station dry web cleaning mechanism disclosed in the utility model, comprising an ultrasonic dust removal device 10, an air supply member 20, a first filter 30 and a second filter 40.
[0038] The ultrasonic dust removal device 10 includes an ultrasonic generator 2 and a dust removal body 1 in the shape of a rectangular shell. Two partitions 3 are provided in the dust removal body 1 to divide the internal chamber of the dust removal body 1 into three independent cavities, among which the cavity in the middle position is the first cavity 11, and the cavities on both sides are the second cavity 12. The ultrasonic generator 2 is arranged in the first cavity 11.
[0039] The air supply member 20 is a blower, and the blower includes an air supply end and an air suction end.
[0040] The first cavity 11 has a first inlet 111 and a first outlet 112. The first inlet 111 is used to connect to the air supply end of the blower to supply air to the first cavity 11. The second cavity 12 has a second inlet 121 and a second outlet 122. The second outlet 122 is used to connect to the air suction end of the blower to form a negative pressure in the second cavity 12.
[0041] One side of the dust removal body 1 is the dust removal side 13, which is arranged parallel to the surface of the roll to be cleaned, and the first outlet 112 and the second inlet 121 are both provided on the dust removal side 13; with the continuous conveyance of the roll to be cleaned, the multi-station dry roll cleaning mechanism can continuously remove dust from the roll.
[0042] Gas is supplied to the first cavity 11 through an air supply source, and the gas in the first cavity 11 generates ultrasonic oscillations under the action of the ultrasonic generator 2. The gas is ejected from the first outlet 112 and acts on the web to be cleaned, so that the dust particles adhered to the surface of the web to be cleaned produce at least one of the three movements of pulling, rolling and sliding, and then separate from the surface of the web; the dust particles separated from the surface of the web float above the surface of the web, and are sucked into the second cavity 12 under the action of the negative pressure of the second cavity 12, and are discharged outward from the second cavity 12, thereby realizing dust removal and cleaning of the surface of the web, so as to reduce the defective rate of the web products.
[0043] Compared with the method of using rubber roller bonding to remove dust in related technologies, the multi-station dry web cleaning mechanism uses a non-contact dry cleaning method to remove dust, which will not cause damage to the product. The ultrasonic vibration can be transmitted to the edge of the web and other positions along with the gas, and the dust removal is more thorough. At the same time, the ultrasonic generator 2 has a long service life and does not require frequent maintenance. It can clean the web for a long time and is more convenient to use.
[0044] Reference Figure 1 The air supply end of the blower is connected to one end of the first filter 30 through a pipe, and the air intake pipe 41 is connected to the other end of the first filter 30 through a pipe, thereby realizing the connection between the air intake pipe 41 and the air supply source, and the first filter 30 can filter the gas entering the air intake pipe 41.
[0045] The air intake end of the blower is connected to one end of the second filter 40 through a pipe, and the exhaust pipe 42 is connected to the other end of the second filter 40 through a pipe, thereby realizing the connection between the exhaust pipe 42 and the air intake source, and the gas discharged from the second cavity 12 is filtered through the second filter 40 and then enters the blower.
[0046] Thus, the dust removal system forms a closed-loop system, and the gas is filtered twice during each circulation process to ensure that the gas entering the first cavity 11 is clean air, thereby reducing the risk of secondary dust contamination of the coil during the dust removal process.
[0047] The dust removal system can be used in clean workshops. It uses the internally circulated clean air as the medium. The dust particles detached from the coils are filtered twice, which will not destroy the air balance of the clean space and thus will not cause secondary pollution.
[0048] Optionally, the first filter 30 is a medium-efficiency filter, and the second filter 40 is a high-efficiency filter. The filtering capacity of the second filter 40 is greater than that of the first filter 30, and the second filter 40 can filter most dust particles. The second filter 40 is connected to an exhaust pipe, through which the dust particles filtered out by the second filter 40 can be discharged outdoors.
[0049] Optionally, the wind pressure in the first cavity 11 is 6KPa-36KPa, for example, 8KPa, 10KPa, 14KPa, 16KPa, 20KPa, 25KPa, 30KPa, etc.; the distance between the first outlet 112 and the coil close to the first outlet 112 is 0.5mm-5mm, for example, 1mm, 1.5mm, 2mm, 3mm, 4mm, etc.
[0050] By making the above settings on the wind pressure in the first cavity 11 and the distance between the first outlet 112 and the coil, a better dust removal effect can be achieved. For dust particles of 3μm on the surface of the coil, a cleaning rate of 97% can be achieved, and for dust particles of 6μm, a cleaning rate of 98% can be achieved, and the dust removal effect is better.
[0051] Reference Figure 3 and Figure 4Since the two second cavities 12 are respectively arranged on both sides of the first cavity 11, the two second inlets 121 are also respectively arranged on both sides of the first outlet 112; the first outlet 112 and the second inlet 121 are both long strips, and the length direction of the first outlet 112 is parallel to the length direction of the second inlet 121, and the length of the second inlet 121 is greater than or equal to the length of the first outlet 112.
[0052] After the dust particles on the coil are separated from the surface of the coil, they are in a floating state under the action of the ultrasonic wave, and the dust particles will float in a certain range around the first outlet 112. Through the above arrangement, the negative pressure area formed by the two second inlets 121 can be increased, which is more conducive to sucking the floating dust particles into the second cavity 12, thereby improving the efficiency of cleaning and dust removal.
[0053] In other embodiments, according to design requirements, the number of the second cavities 12 may be more than two.
[0054] Reference Figure 3 and Figure 4 To facilitate the understanding of those skilled in the art, the two second cavities 12 are named as chamber one 123 and chamber two 124 respectively.
[0055] The dust removal body 1 is provided with an air inlet 14 for connecting to an air supply source and an exhaust port 15 for connecting to an air suction source. The first inlet 111 is connected to the air inlet 14 to realize the air supply to the first cavity 11. The second outlet 122 of chamber one 123 and the second outlet 122 of chamber two 124 are both connected to the exhaust port 15, so as to realize the air suction to the two second cavities 12 at the same time.
[0056] Specifically, an air inlet pipe 41 and an exhaust pipe 42 are connected to the dust removal body 1. The air inlet pipe 41 is connected to the air inlet port 14, and the exhaust pipe 42 is connected to the exhaust port 15, so that the connection between the dust removal body 1 and other components is more convenient.
[0057] Optionally, those skilled in the art may reasonably design the shapes of the air inlet pipe 41 and the exhaust pipe 42 according to the application scenario of the multi-station dry web cleaning mechanism, for example, designing them into a "U" shape, a "G" shape, etc., to improve the convenience of connecting the dust removal body 1 with other components.
[0058] Reference Figure 3 and Figure 4 The first cavity 11 is located between the two partitions 3 and is in the shape of a long strip. The ultrasonic generator 2 is installed in the first cavity 1. Those skilled in the art can adjust the shape and position of the partition 3 according to the installation position of the ultrasonic generator 2.
[0059] Reference Figure 3, the gas in the first cavity 11 flows from the first inlet 111 to the first outlet 112, in other words, the airflow in the first cavity 11 is directed from the first inlet 111 to the first outlet 112. The portion close to the first outlet 112 is the contraction zone 113, and the two ends of the width direction of the contraction zone 113 point to the two second cavities 12 respectively, that is, the width direction of the contraction zone 113 is perpendicular to the airflow direction; the contraction zone 113 is conical, and the width of the contraction zone 113 gradually decreases along the airflow direction, so that the gas flowing to the first outlet 112 can be accelerated to enhance the vibration of the ultrasonic wave, thereby improving the dust removal efficiency.
[0060] Reference Figure 2 and Figure 4 The dust removal body 1 is divided into two dust removal areas 16 along the length direction of the first outlet 112. The dust removal areas 16 correspond to the coils one by one. In other words, the two coils are arranged along the length direction of the dust removal body 1. The gas blown out of the first outlet 112 can act on the two coils at the same time to achieve dust removal and cleaning of the two coils at the same time, thereby realizing multi-station dust removal and improving dust removal efficiency.
[0061] The dust removal body 1 can be set to an appropriate length according to the width of the coils, specifically, the first outlet 112 can cover the edges of the two coils to simultaneously clean and dust the two coils, such as 1000mm, 2000mm, 3000mm, 4000mm, etc.
[0062] In other embodiments, the number of dust removal zones 16 may be set to more than two according to the dust removal requirements for the coiled material.
[0063] Reference Figure 4 The outer cover of the dust removal body 1 is provided with a protective cover 5, which is a sheet metal part and is simpler to produce and process; the protective cover 5 is fixedly connected to the dust removal body by bolts, and the protective cover 5 can protect the dust removal body 1 to ensure the normal use of the multi-station dry coil cleaning mechanism.
[0064] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
