The first magnetic block 140 and the second magnetic block 150 are respectively fixed on two sides of the plurality of metal rods 131, that is, the surfaces of the first magnetic block 140 and the second magnetic block 150 opposite to each other are parallel to the axial direction of the metal rods 131. When the plurality of metal rods 131 rotate, the plurality of metal rods 131 each cut the magnetic field 160, i.e., the magnetic induction wire cutting mechanism 130 may cut the magnetic induction wire in the magnetic field 160 to generate an induced current. It should be noted that, one of the first magnetic block 140 and the second magnetic block 150 may be directly fixed on the plurality of metal rods 131, as shown in fig. 1, but it is necessary to ensure that the magnetic induction wire cutting mechanism 130 can rotate in the magnetic field 160 to cut the magnetic field 160, so as to generate an induced current; the first magnetic block 140 and the second magnetic block 150 may also be fixed on two sides of the magnetic induction wire cutting mechanism 130 through a bracket, and the specific fixing manner of the first magnetic block 140 and the second magnetic block 150 is not limited in the present invention.
The dust removing device 100 is used in combination with a film plating device, wherein the first magnetic block 140 and the second magnetic block 150 are arranged opposite to each other at intervals, the first magnetic block 140 is opposite to the second magnetic block 150 in opposite poles, a stable magnetic field 160 can be formed between the first magnetic block 140 and the second magnetic block 150, the magnetic induction wire cutting mechanism 130 is provided with a plurality of metal rods 131, when the plurality of metal rods 131 cut the magnetic field 160, magnetic induction wires can be cut in the magnetic field 160 to generate magnetic induction current, as the plurality of metal rods 131 are connected into a whole through the insulated conducting wire 132, one end of the insulated conducting wire 132 is connected with the metal sheet 110, the other end of the insulated conducting wire 132 is connected with the film plating device, so that the generated induction current can flow in the metal sheet 110, at the moment, the dust adhering pad 120 attached to the metal sheet 110 can adsorb dust particles with negative charges, and the dust removing treatment can be automatically performed on the film plating device, and the labor intensity of the film plating device in the maintenance process is remarkably reduced.
In order to improve the dust removing effect of the dust removing device 100, as shown in fig. 1 and 2, the insulated wire 132 is located outside the first magnetic block 140 and/or the second magnetic block 150. In one embodiment, the insulated wires 132 are all located outside the first magnetic block 140. In another embodiment, the insulated wires 132 are all located outside the second magnetic block 150. In yet another embodiment, a portion of the insulated wire 132 is located outside the first magnetic block 140 and another portion of the insulated wire 132 is located outside the second magnetic block 150. The dust removing device 100 prevents the plurality of metal rods 131 from participating in the cutting magnetic field 160 during the process of cutting the magnetic field 160, and the insulated wires 132 can increase the induced current generated by the plurality of metal rods 131 during the process of cutting the magnetic field 160, thereby increasing the induced current passing through the metal sheet 110 and improving the dust removing effect of the dust removing device 100.
In order to realize that the plurality of metal rods 131 can cut the magnetic field 160, as shown in fig. 1 and 2, the dust removing device 100 further includes a driving member (not shown) that can drive the plurality of metal rods 131 to rotate, so as to realize that the plurality of metal rods 131 can cut the magnetic field 160, that is, the magnetic induction wire cutting mechanism 130 can cut the magnetic field 160, so as to generate an induction current, so as to ensure that the generated induction current can flow in the metal sheet 110, and at this time, the dust adhesion pad 120 attached to the metal sheet 110 can adsorb dust particles with negative charges, and the dust removing treatment is automatically performed on the film plating device.
The driving member may be a motor or a cylinder, etc. to drive the plurality of metal rods 131 to rotate, but the driving member may also be a member that manually drives the plurality of metal rods 131 to rotate, and the present invention is not limited to the specific form of the driving member.
The type of the dust-sticking pad 120 is various, and in a preferred embodiment, as shown in fig. 1 and 2, the dust-sticking pad 120 includes a substrate 121 and an adhesive layer 122, the adhesive layer 122 is coated on the surface of the substrate 121, and the substrate 121 is attached to the side surface of the metal sheet 110 by using an adhesive, so that the dust-sticking pad 120 and the metal sheet 110 are fixedly connected, and dust particles with negative charges in a working area can be adsorbed by the adhesive layer 122, so that dust removal treatment is performed on the working area.
Of course, in other embodiments, the adhesive layer 122 may be directly coated on the surface of the metal sheet 110, and when the induced current flows in the metal sheet 110, dust particles with negative charges in the working area may be adsorbed by the adhesive layer 122, so as to perform dust removal treatment on the working area.
In addition, as shown in fig. 3 and fig. 4, the present invention further provides a film plating machine 200, where the film plating machine 200 includes a cavity 210, a drum 220, a radio frequency ion source 230, and the dust removing device 100 according to any one of the above claims, the radio frequency ion source 230 is embedded on the cavity 210, the radio frequency ion source 230 can generate plasma in a nearby area, and dust particles in the plasma are negatively charged.
The roller 220 is disposed inside the chamber 210, and the roller 220 is rotatable inside the chamber 210, and a gap is provided between the roller 220 and the chamber 210 to form a coating region 240, and the workpiece is placed in the coating region 240 for coating. It should be noted that the size of the gap between the roller 220 and the cavity 210 can be specifically set according to the requirement, and the present invention is not limited thereto.
The dust removing device 100 is located between the cavity 210 and the drum 220, i.e. the dust removing device 100 is located in the coating region 240 to perform dust removing treatment on the coating region 240. Specifically, as shown in fig. 3, the metal sheet 110 is fixed to a side wall of the roller 220 by screwing, embedding, or the like, the first magnetic block 140 is fixed to a top wall of the cavity 210 by magnetic attraction, and the second magnetic block 150 is fixed to a top wall of the roller 220 by magnetic attraction, so as to realize the fixed connection among the dust removing device 100, the cavity 210, and the roller 220. When the drum 220 rotates, the second magnetic block 150 rotates along with the drum 220, when the second magnetic block 150 rotates to a position opposite to the first magnetic block 140, a stable magnetic field 160 can be generated between the first magnetic block 140 and the second magnetic block 150, when the magnetic induction wire cutting mechanism 130 rotates to cut in the magnetic field 160, induced current can be generated, so that the metal sheet 110 has positive charges, and the dust-sticking pad 120 can adsorb dust particles with negative charges in the coating region 240 to perform dust removal treatment on the coating region 240.
In other embodiments, the metal sheet 110 is fixed to the side wall of the roller 220 by screwing, embedding, or the like, the first magnetic block 140 is fixed to the bottom wall of the cavity 210 by magnetic attraction, and the second magnetic block 150 is fixed to the bottom wall of the roller 220 by magnetic attraction, so as to realize the fixed connection among the dust collector 100, the cavity 210, and the roller 220. The specific positions of the first magnetic block 140 and the second magnetic block 150 are not limited in the present invention, and it is only required that the first magnetic block 140 can be rotated to a position opposite to the second magnetic block 150 or the second magnetic block 150 can be rotated to a position opposite to the first magnetic block 140 in the rotation process, and a stable magnetic field 160 can be generated between the first magnetic block 140 and the second magnetic block 150.
In addition, it should be noted that, since one end of the insulated wire 132 is connected to the metal sheet 110 and the other end of the insulated wire 132 is connected to the coating machine 200, according to the right-hand rule, when the rotation direction of the magnetic induction wire cutting mechanism 130 is set, it is necessary to ensure that the metal sheet 110 is charged positively, and the dust-sticking pad 120 can adsorb the dust particles with negative charges in the coating region 240, so as to perform dust removal treatment on the coating region 240.
In the film plating machine 200, the roller 220 and the cavity 210 have a gap to form a film plating area 240, the dust removing device 100 is located between the cavity 210 and the roller 220, the metal sheet 110 is fixed on the side wall of the roller 220, the first magnetic block 140 is fixed on the top wall of the cavity 210, the second magnetic block 150 is fixed on the top wall of the roller 220, so as to realize the installation and fixation of the dust removing device 100, and the roller 220 is rotatably arranged inside the cavity 210, so as to realize the rotary sputtering film plating on the surface of a workpiece; when the rf ion source 230 works to generate plasma, dust in the plasma is negatively charged, and the dust-sticking pad 120 attached to the metal sheet 110 can adsorb the negatively charged dust impurities, so that the dust removal treatment is automatically performed on the coating machine 200, and the labor intensity of the coating machine 200 in the maintenance process is remarkably reduced.
To further increase the utilization of the induced current, in a preferred embodiment, as shown in fig. 3 and 4, the first magnetic block 140 is located near one end of the rf ion source 230. Because the dust in the area near the rf ion source 230 is negatively charged, when the second magnetic block 150 rotates to a position near one end of the rf ion source 230, a stable magnetic field 160 can be formed between the first magnetic block 140 and the second magnetic block 150, and at this time, the dust-binding pad 120 can adsorb the dust particles with negative charges in the area near the rf ion source 230, so as to improve the utilization ratio of the induced current.
In addition, the length of the first magnetic block 140 in the extending direction of the metal rod 131 is greater than the length of the rf ion source 230 in the rotating direction of the drum 220; or, the length of the second magnetic block 150 in the extending direction of the metal rod 131 is greater than the length of the rf ion source 230 in the rotating direction of the drum 220; alternatively, the lengths of the first magnetic block 140 and the second magnetic block 150 in the extending direction of the metal rod 131 are larger than the length of the rf ion source 230 in the rotating direction of the drum 220. Through the above arrangement, it can be ensured that the second magnetic block 150 has opposite regions with the first magnetic block 140 and the second magnetic block 150 when the second magnetic block 150 rotates to the vicinity of the rf ion source 230 in the rotation process of the drum 220, a stable magnetic field 160 can be generated in the vicinity of the rf ion source 230, the flow of induced current in the metal sheet 110 is ensured, and the dust particles with negative charges in the vicinity of the rf ion source 230 are effectively adsorbed.
In order to effectively perform the dust removal treatment on the coating area 240, as shown in fig. 3, in a preferred embodiment, the magnetic induction wire cutting mechanism 130 is fixed on the second magnetic block 150 by means of magnetic attraction, and a gap exists between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140. In the rotation process of the drum 220, since the magnetic induction wire cutting mechanism 130 and the second magnetic block 150 are fixed together, the drum 220 can be used as a driving member to drive the magnetic induction wire cutting mechanism 130 to cut the magnetic field 160, so as to generate induced current, so that the metal sheet 110 has positive charges, and the dust-sticking pad 120 can adsorb dust particles with negative charges in the coating region 240, so as to perform dust removal treatment on the coating region 240.
In addition, since the first magnetic block 140 is fixed on the top wall of the cavity 210 by means of magnetic attraction, a gap needs to be provided between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 to ensure that the drum 220 can rotate inside the cavity 210, and the magnetic induction wire cutting mechanism 130 can cut the magnetic field 160 to generate induced current, so that the metal sheet 110 has positive charges, and the dust-binding pad 120 can adsorb dust particles with negative charges in the coating region 240 to perform dust removal treatment on the coating region 240.
The gap between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 is 2mm-20mm. When the distance between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 is smaller than 2mm, the first magnetic block 140 is easy to interfere with the rotation of the roller 220, so that the magnetic induction wire cutting mechanism 130 cannot cut the magnetic field 160, and the dust removing device 100 cannot remove dust from the coating region 240. When the distance between the magnetic induction wire cutting mechanism 130 and the second magnetic block 150 is greater than 20mm, the distance between the first magnetic block 140 and the second magnetic block 150 is too large, the magnetic field 160 generated between the first magnetic block 140 and the second magnetic block 150 is weak, so that the induced current generated by the magnetic induction wire cutting mechanism 130 in the process of cutting the magnetic field 160 is small, the dust adsorption capacity of the dust adhesion pad 120 on the dust particles with negative charges in the film coating area 240 is weak, and the dust removing effect of the dust removing device 100 is seriously affected.
Specifically, the distance between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 may be one of 2mm, 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm. Of course, the distance between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 is not limited to the above range of values, but may be other values in the range of 2mm to 20mm. It should be noted that, in the case where the dust removing effect of the dust removing device 100 is not required, the distance between the magnetic induction wire cutting mechanism 130 and the first magnetic block 140 is not limited to the distance setting range, and may be specifically set according to the process requirement, which is not limited in the present invention.
In order to achieve the rotation of the drum 220 inside the cavity 210, as shown in fig. 3 and 4, the coating machine 200 further includes a driving mechanism 250, where the driving mechanism 250 is disposed on the drum 220 by screwing, welding, etc., and the driving mechanism 250 is used to drive the drum 220 to rotate around its axis.
Specifically, as shown in fig. 3, the driving mechanism 250 is a motor 251, and the motor 251 has an output shaft 252, and the output shaft 252 is connected to the drum 220. In the above-mentioned coating machine 200, the motor 251 outputs power to the output shaft 252, and the output shaft 252 can drive the drum 220 to rotate. Of course, the rotation of the drum 220 is not limited to the above-provided motor 251 driving method, but may be a cylinder driving method or other driving method capable of driving the drum 220 to rotate.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
