Description

Technical Field

[0001] The present application relates to the field of vacuum coating technology, and in particular to a swing frame structure and vacuum coating equipment. Background Art

[0002] Vacuum coating is a very important technology in modern manufacturing and surface treatment industries. At present, vacuum coating technology is widely used in high-tech fields such as electronic products, optical components, sensors, etc. Vacuum coating technology is mainly divided into evaporation coating and sputtering coating. Among them, evaporation coating is widely used because of its ability to quickly and conveniently deposit thin films of various materials and relatively low cost. Evaporation coating technology is to sublimate or evaporate raw materials into high-temperature steam through various methods such as resistance heating, induction heating, laser heating, plasma heating or electron beam bombardment, and then cool and deposit them on substrates of various materials such as plastics, metals, ceramics and glass to form a conductive film with certain functions.

[0003] Conductive film is a polymer material with metal plated on the surface. It is widely used in lithium-ion batteries, mainly as a battery current collector in lithium-ion batteries.

[0004] When producing conductive films, the coating process is generally completed through the evaporation coating process. The coating process is in a vacuum environment. Due to the high temperature in the vacuum chamber, the coating layer of the conductive film after coating has a weak bonding ability with the base film, which can easily cause the coating layer to separate from the base film during the winding process. At the same time, some metal dust with poor adhesion will appear on the surface of the conductive film after coating, which will affect the quality of the conductive film during winding, making the coating of the conductive film uneven and even scratching the conductive film.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0040] As described in the background technology, the coating process of the conductive film is in a vacuum environment. Due to the high temperature in the vacuum chamber, when the coating is coated on the base film, the adhesion between the coating and the base film is poor. When the conductive film is rolled up, the coating and the base film are easily separated. At the same time, metal dust with poor adhesion will appear on the surface of the conductive film. During the winding process of the conductive film, the metal dust will affect the quality of the conductive film, making the coating of the conductive film uneven and even scratching the conductive film. Therefore, in order to prevent the metal powder from affecting the production quality of the conductive film and improve the adhesion between the coating and the base film, the inventor of the present application has designed a new swing frame structure, and the swing frame structure of the present application will be described in detail in conjunction with the accompanying drawings.

[0041] It should be noted that the first direction in the present application is a direction parallel to the axis of the winding roller, and the second direction is a direction parallel to the axis of the winding roller. Figure 3 The direction indicated by the letter X in the middle, the third direction is the Figure 5 The direction indicated by the letter Y.

[0042] See also Figures 1 to 5 As shown, the present application provides a swing frame structure, which is at least used for a coating device, in which a winding roller 40 is arranged. The swing frame structure includes a swing frame assembly 10, a roller assembly 20 and a purge assembly 30.

[0043] Among them, the swing frame assembly 10 is at least installed on the outer peripheral side of the winding roller 40 and moves in the direction close to or away from the winding roller 40; the over-roller assembly 20 is arranged on the swing frame assembly 10 to at least be used to transfer the film 50 to the winding roller 40; the purge assembly 30 is arranged on the swing frame assembly 10, and the purge assembly 30 is at least used to purge the powder on the surface of the film 50 between the winding roller 40 and the over-roller assembly 20.

[0044] When the swing frame structure of this embodiment is working, the film 50 has completed the coating process. The film 50 is transferred to the winding roller 40 via the roller assembly 20 on the swing frame assembly 10 and is wound by the winding roller 40. During this process, the purge assembly 30 is turned on to blow the surface of the film 50 between the winding roller 40 and the roller assembly 20 and the surface of the wound film 50 on the winding roller 40. This can not only blow away the loosely bonded powder on the surface of the film 50, so that the powder leaves the film 50, thereby preventing the powder from affecting the quality of the film 50 and scratching the film 50, but also cool the surface of the film 50, thereby improving the bonding strength between the coating and the base film of the film 50, effectively preventing the coating from falling off from the base film during the winding process of the film 50, and extending the service life of the film 50. At the same time, when using the winding roller 40 for winding, as the coil increases, the swing frame assembly 10 has a follow-up movement function, and the swing frame assembly 10 can move in the direction away from the winding roller 40, so that the swing frame assembly 10 maintains a certain distance from the outermost layer of the film 50 on the winding roller 40, thereby ensuring the flatness of the film surface of the film 50 during the winding process; when the coil on the winding roller 40 decreases, the swing frame can gradually move in the direction close to the winding roller 40. Similarly, the swing frame assembly 10 always maintains a certain distance from the outermost layer of the film 50 on the winding roller 40, thereby ensuring the flatness of the film surface of the film 50 during the unwinding process.

[0045] That is to say, compared with the winding method of the coated film 50 in the prior art, the present embodiment adds a purge assembly 30 to the swing frame assembly 10, and the purge assembly 30 can cool the surface of the film 50, thereby improving the bonding force between the coating layer and the base film. At the same time, the purge assembly 30 can also blow off the powder that is not firmly bonded, effectively avoiding the powder from affecting the production quality of the film 50, and avoiding the powder from damaging the film 50, thereby extending the service life of the film 50 to a certain extent. In addition, the swing frame assembly 10 can also move in the direction away from or close to the winding roller 40 as the coil on the winding roller 40 increases or decreases, thereby ensuring the flatness of the film surface of the film 50.

[0046] Specifically, the swing frame structure of the present application is not limited to being used for winding up the film 50 after the evaporation coating process, but is also applicable to winding up the film 50 after the magnetron sputtering process and the film 50 after other different deposition principles.

[0047] Further, see Figure 1As shown, in one embodiment of the present application, the swing frame assembly 10 includes a swing frame body 11, a rotating shaft 12, a transmission component 13 and a driving component 14. Among them, the swing frame body 11 has a roller assembly 20; the rotating shaft 12 is rotatably mounted on a predetermined structure, and the swing frame body 11 is fixedly connected to the rotating shaft 12; the transmission component 13 is mounted on the predetermined structure and is drivingly connected to the swing frame body 11; the driving component 14 is mounted on the predetermined structure, and the driving component 14 is drivingly connected to the transmission component 13, so as to drive the transmission component 13 to drive the swing frame body 11 to rotate with the rotating shaft 12 to move toward or away from the winding roller 40.

[0048] That is, when the film 50 is transferred to the winding roller 40 via the roller assembly 20 and wound by the winding roller 40, when the coil on the winding roller 40 gradually increases, the driving component 14 drives the swing frame body 11 to rotate along with the rotating shaft 12 through the transmission component 13 and moves in a direction away from the winding roller 40, so that the swing frame body 11 maintains a certain distance from the outermost layer of the coil on the winding roller 40, ensuring the flatness of the film surface of the film 50 during the winding process; when the coil on the winding roller 40 gradually decreases, the driving component 14 drives the swing frame body 11 to rotate along with the rotating shaft 12 through the transmission component 13 and moves in a direction close to the winding roller 40, so that the swing frame body 11 maintains a certain distance from the outermost layer of the coil on the winding roller 40, ensuring the flatness of the film surface of the film 50 during the winding process. Among them, the swing frame body 11 never contacts the outermost layer of the coil on the winding roller 40. The present invention can realize the swinging of the swing frame body 11 by utilizing the cooperation of the driving component 14 and the transmission component 13, and has a simple structure and convenient operation. In addition, the rotating shaft 12 provided in the present invention can play a role of rotational support for the swing frame body 11.

[0049] Further, see Figure 1 As shown, in another embodiment of the present application, a roller assembly 20 is provided on the swing frame body 11; the rotating shaft 12 is fixedly connected to the predetermined structure, and the swing frame body 11 is rotatably mounted on the rotating shaft 12; the transmission component 13 is mounted on the predetermined structure and is transmission-connected to the swing frame body 11; the driving component 14 is mounted on the predetermined structure, and the driving component 14 is drivingly connected to the transmission component 13, so as to drive the transmission component 13 to drive the swing frame body 11 to rotate around the rotating shaft 12 to move toward or away from the winding roller 40.

[0050] Specifically, the predetermined structure in the present application is a vacuum chamber plate in a coating device.

[0051] Specifically, see Figure 1As shown, the driving component 14 in this embodiment includes a fixed seat 141 and an electric push rod 142. Among them, the fixed seat 141 is fixedly connected to the predetermined structure; the electric push rod 142 is rotatably connected to the fixed seat 141. Since the electric push rod 142 is small in size, high in precision, and has low maintenance cost, this embodiment uses the electric push rod 142 as the driving component 14, which can reduce the footprint of the swing frame structure in the coating equipment, thereby improving the space utilization rate of the coating equipment, and at the same time, it can better control the transmission component 13 to drive the swing frame body 11 to swing with higher accuracy. In addition, in this embodiment, the electric push rod 142 is rotatably connected to the fixed seat 141, so that the electric push rod 142 can drive the transmission component 13 from different directions and angles, thereby driving the swing frame body 11 to swing.

[0052] Further, see Figure 1 As shown, the transmission component 13 in this embodiment includes a support shaft 131, a connecting sleeve 132 and a connecting rod 135. Specifically, the transmission component 13 can not only drive the swing frame body 11 to swing under the drive of the driving component 14, but also play a supporting role for the swing frame body 11.

[0053] Among them, the support shaft 131 is installed on a predetermined structure; the connecting sleeve 132 is rotatably sleeved on the support shaft 131, and the outer periphery of the connecting sleeve 132 is provided with a first connecting section 133 and a second connecting section 134 at intervals, and the first connecting section 133 and the second connecting section 134 both extend along the radial direction of the support shaft 131, and the end of the first connecting section 133 away from the connecting sleeve 132 is hinged to the electric push rod 142; one end of the connecting rod 135 is connected to the swing frame body 11, and the other end of the connecting rod 135 is hinged to the end of the second connecting section 134 away from the connecting sleeve 132. Specifically, the support shaft 131 can provide a rotation support point for the connecting sleeve 132, and the first connecting section 133 can transmit the driving force of the electric push rod 142 to the connecting sleeve 132, thereby transmitting it to the second connecting section 134, and then to the connecting rod 135, thereby driving the swing frame body 11 to swing, and the structure is simple and easy to operate. That is, when the electric push rod 142 is extended, the first connecting section 133 can drive the connecting sleeve 132 to move clockwise, so that the second connecting section 134 can move clockwise, and then the swing frame body 11 can be driven to move in a direction away from the winding roller 40 through the connecting rod 135; when the electric push rod 142 is shortened, the first connecting section 133 can drive the connecting sleeve 132 to move counterclockwise, so that the second connecting section 134 can move counterclockwise, and then the swing frame body 11 can be driven to move in a direction close to the winding roller 40 through the connecting rod 135. In addition, in this embodiment, the first connecting section 133 is hinged to the electric push rod 142, and the second connecting section 134 is hinged to the connecting rod 135, which can improve the overall flexibility of the transmission component 13, prevent the transmission component 13 from breaking during the transmission process, and improve the production efficiency of the film 50.

[0054] Further, see Figure 1 As shown, the roller assembly 20 in this embodiment includes at least three rollers 21, and at least three of the three rollers 21 are arranged in a triangle. In this way, the stability of the film 50 in transmission on the roller assembly 20 can be guaranteed. The existence of the roller assembly 20 can transport the film 50 smoothly and prevent the film 50 from wrinkling during the transmission process. In other words, no matter how many rollers 21 the roller assembly 20 includes, it is sufficient to ensure that three of the rollers 21 are arranged in a triangle. Specifically, the roller assembly 20 may include three, four, five, six or more rollers 21, and the present application does not make specific limitations, as long as the film 50 can be transported and the film 50 can be smoothly wound. The appendix of this embodiment Figure 1 The case where the roller assembly 20 includes three rollers 21 is shown.

[0055] Further, see Figures 2 to 5 As shown, the purge assembly 30 in this embodiment includes an air knife 31, and the air knife 31 has a ventilation cavity 311 and an air outlet 312. The air outlet 312 extends from the outer surface of the air knife 31 toward the inside of the air knife 31 and is connected to the ventilation cavity 311. Specifically, an air supply system is also provided in the coating equipment, and the air supply system can supply gas of a certain pressure to the air knife 31. After the gas enters the ventilation cavity 311, it is blown out through the air outlet 312. The air knife 31 has the advantages of light weight, stable air outlet performance, and large air volume. When the air knife 31 is set on the swing frame body 11, the surface of the film 50 between the roller assembly 20 and the winding roller 40 can be quickly cooled, and the bonding force between the coating and the base film can be enhanced. At the same time, the powder that is not firmly bonded to the surface of the film 50 can be blown off to avoid the damage of the film 50 by these powders, thereby improving the production quality of the film 50.

[0056] Specifically, the gas blown out by the wind knife 31 in this embodiment can be nitrogen. With such a configuration, when the wind knife 31 blows on the surface of the film 50, the blown nitrogen can enter between the adjacent layers of the film 50 after it is rolled up, and to a certain extent, avoid the film 50 being moved out of the vacuum chamber and exposed to the air for a short time, and the air entering between the layers of the film 50 and causing the film 50 to be oxidized. The nitrogen can protect the film 50. Of course, the gas blown out by the wind knife 31 in this application can also be other inert gases such as helium, neon, argon, etc., and any other deformation methods under the conception of this application are within the protection scope of this application.

[0057] Further, see Figures 2 to 4As shown, the wind knife 31 in this embodiment extends along the first direction, and the air outlet holes 312 include a plurality of air outlet holes 312, which are arranged at intervals along the first direction. In this way, not only can the cooling process of the film 50 be accelerated, the bonding force between the coating layer and the base film be quickly improved, and the stability of the overall structure of the film 50 be ensured, but also the surface of the film 50 can be fully purged, and the loosely bonded powder can be completely blown off from the surface of the film 50, effectively ensuring the production quality of the film 50 and extending the service life of the film 50.

[0058] Further, see Figure 3 to Figure 4 As shown, the air outlet holes 312 in this embodiment include multiple rows, and the multiple rows of air outlet holes 312 are spaced apart along the second direction, and each air outlet hole 312 includes at least one air outlet hole 312. That is to say, the air outlet holes 312 in this application may include one row, two rows, three rows or more than three rows, and each air outlet hole 312 may include one air outlet hole 312, two air outlet holes 312, three air outlet holes 312 or more than three air outlet holes 312. This application does not make specific restrictions and can be designed according to actual processing requirements. In this way, not only can the cooling process of the film 50 be accelerated, the bonding force between the coating and the base film can be quickly improved, and the stability of the overall structure of the film 50 can be ensured, but also the surface of the film 50 can be fully purged, and the loosely bonded powder can be completely blown off from the surface of the film 50, effectively ensuring the production quality of the film 50 and extending the service life of the film 50.

[0059] Specifically, see Figure 4 As shown, the air outlet holes 312 in this embodiment are preferably arranged in two rows of air outlet holes 312, and the two rows of air outlet holes 312 are arranged at intervals and diagonally in the second direction, and along the third direction, the distances between the two rows of air outlet holes 312 and the mid-vertical plane 3121 gradually increase. In this way, when the wind knife 31 starts to blow air, the gases blown out of the two rows of air outlet holes 312 will not affect each other, and the two rows of air outlet holes 312 will respectively blow out the loosely adhered dust from the opposite sides of the film 50 (the opposite sides are the opposite sides along the width direction of the film 50), thereby improving the blowing efficiency of the wind knife 31.

[0060] Further, see Figure 5As shown, the wind knife 31 in this embodiment has a mid-vertical surface 3121, and the wind knife 31 also has a first section 3122 located on the first side of the mid-vertical surface 3121 and a second section 3123 located on the second side of the mid-vertical surface 3121. At least one air outlet 312 is provided on each of the first section 3122 and the second section 3123. Along the third direction, the distance between the air outlet 312 located in the first section 3122 and the mid-vertical surface 3121, and the distance between the air outlet 312 located in the second section 3123 and the mid-vertical surface 3121 are gradually increased. In this way, the air outlet 312 located in the first section 3122 can blow out the loosely bonded dust from the right side of the surface of the film 50, and the air outlet 312 located in the second section 3123 can blow out the loosely bonded dust from the left side of the surface of the film 50, thereby improving the blowing efficiency of the wind knife 31. It can be understood that the left side of the surface of the film 50 is one side along the width direction of the film 50 , and the right side of the surface of the film 50 is the other side along the width direction of the film 50 .

[0061] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: Compared with the film winding method in the prior art, the purge assembly added to the swing frame assembly of the present application makes up for the weak bonding between the coating and the base film, and the presence of loosely bonded dust on the surface of the film will affect the quality of the film. The purge assembly can quickly cool the film, thereby improving the bonding between the coating and the base film. At the same time, it can also purge loosely bonded powder, thereby preventing the powder from damaging the film. In addition, the swing frame assembly of the present application can also maintain a certain distance from the outermost layer of the coil on the winding roller to ensure the flatness of the film surface during the winding process.

[0062] On the other hand, the embodiment of the present application further provides a vacuum coating device, which includes the above-mentioned swing frame structure, and thus the vacuum coating device includes all the technical effects of the above-mentioned swing frame structure. Since the technical effects of the swing frame structure have been described in detail above, they will not be repeated here.

[0063] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0064] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0065] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
