Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a polishing device and a coating system. Background Technology

[0002] Vacuum coating technologies are mainly divided into two categories: Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). PVD technology includes vacuum evaporation, sputtering, and ion plating, while CVD technology is a method of forming a thin film on the surface of a substrate through a chemical reaction.

[0003] Among them, the vacuum coating machine using PVD technology uses filamentous materials such as copper wire or aluminum wire as evaporation raw materials. After the filamentous material is wound on the wire spool, the wire spool is placed on the wire spool rack in the evaporation chamber and fed into the evaporation boat through the wire feeding mechanism to facilitate the evaporation coating operation on the substrate.

[0004] However, during storage, a metal oxide film forms on the surface of the filamentous material, which also accumulates dust and other impurities. When the filamentous material is heated and melted inside the evaporation boat, the temperature inside the boat is the melting point of the filamentous material. Since the melting point of the metal oxide film is higher than that of the filamentous material, the metal oxide film remains solid. As the liquid filamentous material boils violently, metal droplets penetrate the metal oxide film and sputter. If the sputtered molten metal lands on the substrate inside the vacuum coating machine, it will form defects such as protrusions, particles, and pinholes, affecting the quality of the vapor deposition process. During this process, dust will affect the uniformity of the surface tension of the metal droplets, also causing metal droplet sputtering, further degrading the quality of the vapor deposition process. Utility Model Content

[0005] In view of this, the present invention provides a grinding device and a coating system to solve the problem that during the storage of filamentous materials, a metal oxide film forms on its surface, which is also covered with dust and other impurities. When the filamentous material enters the evaporation boat for heating and melting, the temperature inside the evaporation boat is the melting point of the filamentous material. However, since the melting point of the metal oxide film is higher than that of the filamentous material, the metal oxide film remains solid. As the liquid filamentous material boils violently, metal droplets pass through the metal oxide film and sputter. If the sputtered liquid metal falls onto the substrate in the vacuum coating machine, it will form defects such as protrusions, particles, and pinholes, affecting the quality of the vapor deposition process. During this process, dust will affect the uniformity of the surface tension of the metal droplets, also causing metal droplet sputtering, further leading to a decrease in the quality of the vapor deposition process.

[0006] In a first aspect, this utility model provides a polishing device, comprising:

[0007] The grinding unit includes an installation structure and a grinding structure. The installation structure has an installation channel for setting the grinding structure. The grinding structure is spiral-shaped and has a grinding channel for passing through the workpiece to be ground. The hardness of the grinding structure is greater than the hardness of the workpiece to be ground. Along the radial direction of the grinding channel, the size of the grinding channel is not greater than the size of the workpiece to be ground, so that when the workpiece to be ground passes through the grinding channel, the grinding structure is used to grind the surface of the workpiece to be ground.

[0008] Beneficial Effects: By setting up a grinding unit, which includes a mounting structure and a grinding structure, the grinding unit supports the grinding structure to fix its position. The grinding structure has a grinding channel, and its hardness is greater than that of the workpiece to be ground. The radial dimension of the grinding channel is not greater than that of the workpiece to be ground. Based on this, when the workpiece passes through the grinding channel, the grinding structure can grind the surface of the workpiece to remove oxide film and dust. This avoids sputtering of the workpiece during vapor deposition, which affects the treatment effect on the substrate, thus improving the purity of the workpiece and ultimately enhancing the reliability of the substrate coating.

[0018] The fixing unit and the grinding unit are detachably connected. Based on this, after grinding the workpiece for a period of time, the grinding unit can be replaced to ensure the grinding effect of the workpiece, thereby improving the completeness of the grinding and achieving the technical effect of reliable use of the grinding device.

[0019] By defining the axial direction along the grinding channel, the size of the grinding unit is equal to the size of the first receiving cavity.

[0025] Beneficial effects: By setting up a scraper unit, the scraper unit can scrape off the powder formed after grinding on the workpiece, improve the metal purity of the workpiece, and prevent the powder on the surface of the workpiece from affecting the vapor deposition effect.

[0026] By setting up a collection unit, the grinding powder can be collected, preventing a large amount of grinding powder from falling into the external environment and avoiding the need for users to collect and process the grinding powder. This achieves the technical effect of improving the ease of use of the grinding device.

[0027] In one optional embodiment, the scraper unit is detachably connected to the fixing unit;

[0028] And / or, the scraper unit is a scraper unit made of rubber.

[0029] Beneficial effects: By limiting the detachable connection between the scraper unit and the fixed unit, the scraper unit can be replaced when it becomes worn, thereby improving the reliability of the grinding device.

[0030] By defining the scraper unit as a scraper unit made of rubber, the friction between the scraper unit and the workpiece to be polished can be increased, thereby improving the reliability of powder removal from the surface of the workpiece.

[0032] And / or, the polishing apparatus includes:

[0034] Beneficial effects: After the workpiece passes through the grinding channel, it can be placed directly in the second and third channels, and the grinding unit can be directly located in the first receiving cavity, reducing installation difficulty. Based on this, grinding efficiency can be improved, thereby enhancing the ease of use of the grinding device.

[0035] By setting a base, the angle of the fixing unit relative to the base can be adjusted according to actual needs. That is, the position of the inlet and outlet can be adjusted according to the actual tilt angle of the workpiece to be ground, so that the axial extension direction of the workpiece to be ground is parallel to the line connecting the inlet and outlet, thereby achieving the technical effect of improving the ease of use of the grinding device.

The radial dimension of the fixing member is greater than the radial dimension of the connector and the radial dimension of the fixing member is greater than the radial dimension of the fifth threaded hole. When the connector passes through the arc groove and is threadedly connected to the fifth threaded hole, the rotation angle of the fixing unit is fixed by the cooperation between the fixing member and the base.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0061] According to an embodiment of the present invention, a polishing device is provided, comprising:

[0062] The grinding unit 1 includes an installation structure and a grinding structure. The installation structure has an installation channel for setting the grinding structure. The grinding structure is spiral-shaped and has a grinding channel for passing through the workpiece 2 to be ground. The hardness of the grinding structure is greater than the hardness of the workpiece 2 to be ground. Along the radial direction of the grinding channel, the size of the grinding channel is not greater than the size of the workpiece 2 to be ground, so that when the workpiece 2 to be ground passes through the grinding channel, the grinding structure is used to grind the surface of the workpiece 2 to be ground.

[0063] In the polishing apparatus of this embodiment, a polishing unit 1 is provided, which includes a mounting structure and a polishing structure. The mounting structure supports the polishing structure to fix its position. The polishing structure has a polishing channel, and the hardness of the polishing structure is greater than that of the workpiece 2 to be polished. The radial dimension of the polishing channel is not greater than the radial dimension of the workpiece 2 to be polished. Based on this, when the workpiece 2 to be polished passes through the polishing channel, the polishing structure can polish the surface of the workpiece 2 to remove the oxide film and dust from its surface. This avoids sputtering of the workpiece 2 during the vapor deposition process, which would affect the treatment effect on the substrate, as is done in related technologies. This improves the purity of the workpiece 2 and ultimately enhances the reliability of the substrate coating.

[0064] Furthermore, the polishing device has a simple structure and can complete the cleaning process during the transmission process of the workpiece 2 itself without the need for other drive structures, thereby reducing the manufacturing difficulty of the polishing device and achieving the technical effect of improving the ease of use of the polishing device.

[0065] In other embodiments, the grinding structure is defined as annular, depending on the design of the grinding device. Compared to other embodiments, in this embodiment, by defining the grinding structure as spiral, all positions of the workpiece 2 to be ground can contact the grinding structure when it passes through the grinding channel. This allows for complete grinding of the workpiece 2 while saving the raw materials required to manufacture the grinding unit 1, thereby achieving the technical effect of reducing the manufacturing cost of the grinding device.

[0066] Furthermore, the shape of the grinding structure is not limited. It can be brush-shaped, or it can be a spiral formed by winding filaments with the hollow spiral structure serving as a grinding channel, or it can be any other shape. As long as it can achieve the grinding of the workpiece 2, it is within the protection scope of this utility model.

[0067] Furthermore, the grinding structure can be compressed radially. In this case, the radial dimension of the grinding channel can be smaller than the radial dimension of the workpiece 2 to be ground, thereby increasing the pressure of the grinding structure on the workpiece 2 and improving the grinding effect. Alternatively, the grinding structure can be rigid and cannot be compressed radially. In this case, the radial dimension of the grinding channel can be equal to the radial dimension of the workpiece 2 to be ground.

[0068] Preferably, the mounting structure is spiral-shaped. Of course, in other embodiments, the shape of the mounting structure may be adjusted according to the design of the grinding device; for example, the mounting structure may be cylindrical, all of which are within the scope of protection of this utility model. Compared to other embodiments, this embodiment, by limiting the mounting structure to a spiral shape, can reduce the raw materials required to manufacture the mounting structure, thereby achieving the technical effect of reducing the manufacturing cost of the grinding device.

[0069] Furthermore, in this embodiment, the part to be polished 2 is the part to be vapor-deposited, that is, the polishing device in this embodiment is set on a vacuum coating machine to perform polishing operations on the part to be vapor-deposited. At this time, the part to be polished 2 is aluminum wire, and the polishing structure is made of diamond material. As an alternative implementation, the material of the polishing structure can be adapted to different materials of the part to be polished 2. As long as the material of the polishing structure can be polished by the polishing structure, it is within the protection scope of this utility model.

[0070] Of course, in other embodiments, the polishing device can also be mounted on other devices, in which case the type of workpiece 2 to be polished can be adjusted.

[0071] In addition, combined Figure 1 As shown, in this embodiment, the polishing device includes:

[0072] The fixing unit 3 is provided with a first receiving cavity for accommodating the grinding unit 1. The fixing unit 3 is connected to the grinding unit 1. The first end face 301 of the fixing unit 3 is provided with an inlet, and the second end face 302 of the fixing unit 3 is provided with an outlet 3021. Both the inlet and the outlet 3021 are connected to the first receiving cavity so that the workpiece 2 to be ground can be inserted into the grinding channel through the inlet and exited through the outlet 3021.

[0073] By setting the fixing unit 3, the grinding unit 1 can be supported, thereby achieving the technical effect of improving the positional stability of the grinding unit 1.

[0074] The fixing unit 3 is a shell. As an alternative implementation, the fixing unit 3 can also be a frame or other shapes.

[0075] Furthermore, along the axial direction of the grinding unit 1, the inlet is located below the outlet 3021. In this embodiment, the axial direction of the grinding unit 1 is... Figure 1 The Z-axis direction is shown. Of course, in other embodiments, the axial direction of the grinding unit 1 may be adjusted depending on the design of the grinding device.

[0076] By limiting the inlet to below the outlet 3021, the powder after grinding can fall under the action of gravity, reducing the amount of powder on the surface of the workpiece 2 to be ground, and avoiding the powder from affecting the vapor deposition effect of the workpiece 2 to be ground, thereby achieving the technical effect of improving the reliability of the grinding device.

[0077] Of course, in other embodiments, depending on the design of the grinding device, the inlet may be located above the outlet 3021, or the relative positions between the inlet and outlet 3021 may be adjusted according to actual needs. Simultaneously, the positions of the scraper unit 5 and the collecting unit 6 may be adjusted accordingly.

[0078] As an alternative implementation, the grinding device may not include the fixing unit 3, or the workpiece 2 to be ground may not move, and the grinding device may be manually driven to move on the workpiece 2 to perform the grinding operation.

[0079] Meanwhile, in other embodiments, the first end face 301 and the second end face 302 of the fixing unit 3 can be the same face, both of which are within the protection scope of this utility model.

[0080] Furthermore, in this embodiment, the fixing unit 3 and the polishing unit 1 are detachably connected. Therefore, after polishing the workpiece 2 for a period of time, the polishing unit 1 can be replaced to ensure the polishing effect of the workpiece 2, thereby improving the completeness of the polishing and achieving the technical effect of reliable use of the polishing device.

[0081] Among them, combined Figure 1 As shown, along the axial direction of the grinding channel, the size of the grinding unit 1 is equal to the size of the first receiving cavity. Based on this, the grinding unit 1 is positioned such that along the axial direction of the grinding channel... Figure 1 The Z-axis dimension is made as long as possible, which increases the number of contact points between the grinding unit 1 and the workpiece 2 to be ground, thereby improving the technical effect of grinding the workpiece 2 completely.

[0082] Furthermore, grinding unit 1 along Figure 1 The dimensions of the X and Y axes shown are respectively equal to the dimensions along the first receiving cavity. Figure 1 The dimensions of the X and Y axes shown indicate that the length and width of the polishing unit 1 are equal to the length and width of the first receiving cavity, respectively. Based on this, the first receiving cavity can define the position of the polishing unit 1, improving the stability of its position.

[0083] Specifically, along the axial direction of the grinding channel, the grinding unit 1 abuts against the inner wall of the first receiving cavity, so that the grinding unit 1 is detachably connected to the fixing unit 3.

[0084] The detachable connection between the grinding unit 1 and the fixed unit 3 is achieved by abutting each other, without the need for an additional structure. This improves the ease of detachable connection between the grinding unit 1 and the fixed unit 3, thereby achieving the technical effect of improving the ease of manufacturing the grinding device.

[0085] Of course, in other embodiments, the detachable connection method between the fixing unit 3 and the grinding unit 1 can be adjusted according to the different designs of the grinding device. For example, the grinding unit 1 can be connected along... Figure 1 The dimensions of the X, Y, and Z axes shown are smaller than those along the first receiving cavity. Figure 1 The dimensions of the X, Y, and Z axes are shown. The grinding unit 1 has a first threaded hole, and the fixing unit 3 has a second threaded hole that mates with the first threaded hole. Threaded connectors such as bolts or screws can be used to thread the first threaded hole and its corresponding second threaded hole. Alternatively, the fixing unit 3 and the grinding unit 1 can be fixedly connected or integrated, both of which are within the protection scope of this utility model.

[0086] As an alternative implementation, it is also possible to define the structure along the axial direction of the grinding unit 1, with the inlet located below the outlet 3021, the fixing unit 3 detachably connected to the grinding unit 1, and the size of the grinding unit 1 along the axis of the grinding channel being equal to the size of the first receiving cavity, or any combination of two structures, all of which are within the protection scope of this utility model.

[0087] In addition, combined Figure 1As shown, in this embodiment, the first side 303 of the fixing unit 3 is provided with a first opening communicating with the first receiving cavity. The inlet is connected to the first side 303 of the fixing unit 3 through the second channel 304, and the outlet 3021 is connected to the first side 303 of the fixing unit 3 through the third channel 305. After the workpiece 2 to be polished is inserted into the polishing channel, the workpiece 2 to be polished is placed in the inlet through the second channel 304 and in the outlet 3021 through the third channel 305, so that the polishing unit 1 is placed in the first receiving cavity through the first opening.

[0088] Furthermore, combined Figure 1 As shown, in this embodiment, the polishing device includes:

[0089] A limiting unit 4 is disposed on the first side 303 of the fixing unit 3 and is detachably connected to the first side 303 of the fixing unit 3. The limiting unit 4 is used to limit the position of the grinding unit 1. Based on this, the technical effect of improving the positional reliability of the grinding unit 1 can be achieved.

[0090] Among them, combined Figure 1 As shown, in this embodiment, the limiting unit 4 along... Figure 1 The directional dimension of the Y-axis shown is equal to that along the first opening. Figure 1 The Y-axis dimension shown is along the limiting unit 4. Figure 1 The dimension along the Z-axis shown is smaller than that along the first opening. Figure 1 The Z-axis directional dimension is shown.

[0091] Specifically, the limiting unit 4 is a plate-like structure, and the limiting unit 4 is parallel to... Figure 1 The two ends of the Y-axis shown are respectively connected to the fixed unit 3 by threads. That is, the limiting unit 4 is provided with a third thread, and the first side 303 of the fixed unit 3 is provided with a fourth thread at the corresponding position. The fixed unit 3 and the limiting unit 4 are connected by bolts or screws to both the third thread and the fourth thread to achieve a detachable connection between the fixed unit 3 and the limiting unit 4.

[0092] As an alternative implementation, the limiting unit 4 can also be a block structure. Alternatively, the method of detachable connection between the limiting unit 4 and the fixing unit 3 can be adjusted; for example, the limiting unit 4 can be positioned along... Figure 1 One side of the limiting unit 4 is hinged to the fixing unit 3 along the Y-axis, and the other side is detachably connected to the fixing unit 3. Alternatively, both the limiting unit 4 and the fixing unit 3 may have through holes, and a pin may pass through the through holes of the limiting unit 4 and the fixing unit 3 to achieve a detachable connection between the limiting unit 4 and the fixing unit 3.

[0093] Of course, in other embodiments, depending on the design of the grinding device, the limiting unit 4 and the fixing unit 3 may be fixedly connected or integrated, all of which are within the protection scope of this utility model.

[0094] Alternatively, the grinding device may not include the limiting unit 4.

[0095] In other embodiments, depending on the design of the grinding device, the size of the limiting unit 4 and the size of the first opening are adjusted, for example, by combining... Figure 2 As shown, the width and height dimensions of the limiting unit 4 are not less than the width and height dimensions of the first opening, and are both within the protection scope of this utility model.

[0096] As an alternative implementation, the fixed unit 3 does not have a second channel 304 and a third channel 305, and the grinding unit 1 is already located in the first receiving cavity. In this case, the workpiece 2 to be ground passes through the inlet and grinding channel to the outlet 3021, so that the grinding unit 1 can perform the grinding operation on the workpiece 2. Compared to other embodiments, this embodiment eliminates the need for a passing-through operation, avoiding the situation where, during the passing-through process, after the workpiece 2 enters the grinding channel through the inlet, the user cannot clearly see the situation inside the grinding channel, which could easily cause the workpiece 2 to be misaligned with the outlet 3021 for a short period, reducing grinding efficiency. In this embodiment, after the workpiece 2 passes through the grinding channel, it is directly placed in the second channel 304 and the third channel 305, and the grinding unit 1 is directly located in the first receiving cavity, reducing installation difficulty. Based on this, grinding efficiency can be improved, thereby achieving the technical effect of improving the ease of use of the grinding device.

[0097] In addition, combined Figure 1 As shown, in this embodiment, the polishing device includes:

[0098] The scraper unit 5 is disposed on the second end face 302 of the fixed unit 3. The scraper unit 5 includes a first channel for setting the workpiece 2 to be polished, so that when the workpiece 2 to be polished slides in the first channel, the scraper unit 5 can scrape off the powder formed after the workpiece 2 to be polished.

[0099] Among them, by setting scraper unit 5, scraper unit 5 can scrape off the powder formed after grinding on the workpiece 2, improve the metal purity of the workpiece 2, and avoid the powder on the surface of the workpiece 2 from affecting the vapor deposition effect.

[0100] Preferably, the scraper unit 5 is a scraper unit made of rubber. Based on this, the friction between the scraper unit 5 and the workpiece 2 to be polished can be increased, thereby achieving the technical effect of improving the reliability of removing powder from the surface of the workpiece 2.

[0101] Furthermore, the scraper unit 5 is connected to the fixing unit 3 through an intermediate structure. Based on this, the connection points between the scraper unit 5 and the fixing unit 3 can be increased, thereby improving the technical effect of enhancing the connection reliability between the scraper unit 5 and the fixing unit 3. As an alternative implementation, the scraper unit 5 can also be directly connected to the fixing unit 3.

[0102] The intermediate structure is a plate-like structure. As an alternative implementation, the intermediate structure can also be a block-like structure.

[0103] As an alternative implementation, the scraper unit 5 can also be a scraper unit made of cotton. Alternatively, it can be made of other materials capable of removing powder from the surface of the workpiece 2 to be polished.

[0104] Of course, in other embodiments, the grinding device may not include the scraper unit 5, and the workpiece 2 to be ground may be scraped directly through the outlet 3021.

[0105] Preferably, the scraper unit 5 is detachably connected to the fixing unit 3. Therefore, when the scraper unit 5 becomes worn, it can be replaced, thereby improving the reliability of the grinding device.

[0106] Among them, the scraper unit 5 and the fixing unit 3 are detachably connected by threads. That is, the scraper unit 5 is connected to the fixing unit 3 by threads through the intermediate structure. The detachable threaded connection is a mature technology and will not be elaborated on here.

[0107] Of course, in other embodiments, the detachable connection between the scraper unit 5 and the fixing unit 3 can be adjusted depending on the design of the grinding device. Alternatively, the connection between the scraper unit 5 and the fixing unit 3 can be fixed, all of which are within the protection scope of this utility model.

[0108] In other embodiments, depending on the design of the grinding device, the scraper unit 5 is limited to being detachably connected to the fixing unit 3, or the scraper unit 5 is limited to being a scraper unit made of rubber.

[0109] In addition, combined Figure 1 As shown, in this embodiment, the polishing device includes:

[0110] The collecting unit 6 is disposed on the first end face 301 of the fixing unit 3. The collecting unit 6 includes a second receiving cavity with a second opening. The second opening communicates with the first receiving cavity through an inlet and a second channel 304, and is used to collect fallen grinding powder. That is, the collecting unit 6 is a collecting box. By setting the collecting unit 6, the grinding powder can be collected, avoiding a large amount of grinding powder falling into the external environment and requiring the user to collect and process the grinding powder separately, thereby achieving the technical effect of improving the ease of use of the grinding device.

[0111] Furthermore, on the side of the intermediate structure, on the extension surface of the first side 303 of the fixing unit 3, a fourth channel is provided. The workpiece 2 to be polished is placed directly into the fourth channel after passing through the scraper unit 5, thus defining the position of the workpiece 2 and allowing it to pass through to the first channel. On the side of the collecting unit 6, on the extension surface of the first side 303 of the fixing unit 3, a fifth channel is provided, communicating with the first and second receiving cavities. The fifth channel allows for the insertion and connection of the workpiece 2 to the collecting unit 6, thereby improving the ease of installation of the workpiece 2.

[0112] As an alternative implementation, the scraper unit 5 may not have a fourth channel on its side, the collection unit 6 may not have a fifth channel on its side, and the bottom surface of the collection unit 6 may have a positioning hole that communicates with the second receiving cavity. The workpiece 2 to be polished may pass through the positioning hole, the inlet, the polishing channel, the outlet 3021 and the first channel to the outside in sequence.

[0113] Of course, in other embodiments, the shape of the collecting unit 6 may be adjusted depending on the design of the polishing device.

[0114] Alternatively, the grinding device may not include the collection unit 6.

[0115] In other embodiments, depending on the design of the polishing device, the polishing device is limited to include a scraper unit 5, or the polishing device is limited to include a collection unit 6.

[0116] In addition, combined Figure 1 As shown, in this embodiment, the polishing device includes:

[0117] The base 7 is detachably connected to the fixing unit 3 and is used to adjust the rotation angle of the fixing unit 3 relative to the base 7.

[0118] Based on this, the angle of the fixing unit 3 relative to the base 7 can be adjusted according to actual needs. That is, the positions of the inlet and outlet 3021 can be adjusted according to the actual tilt angle of the workpiece 2 to be polished, so that the axial extension direction of the workpiece 2 to be polished is parallel to the line connecting the inlet and outlet 3021, thereby achieving the technical effect of improving the ease of use of the polishing device.

[0119] In this embodiment, the second side 306 of the fixing unit 3 is provided with an arc-shaped groove 307, and the base 7 is provided with a fifth threaded hole corresponding to the arc-shaped groove 307. The grinding device includes:

[0120] The first connecting structure 8 includes a connector and a fixing member. The surface of the connector is provided with a first thread corresponding to the fifth threaded hole. The radial dimension of the fixing member is greater than the radial dimension of the connector, and the radial dimension of the fixing member is greater than the radial dimension of the fifth threaded hole. When the connector passes through the arc groove 307 and is threadedly connected to the fifth threaded hole, the rotation angle of the fixing unit 3 is fixed by the cooperation between the fixing member and the base 7. That is, the fixing unit 3 is clamped by the pressure between the fixing member and the base 7 to fix the position of the fixing unit 3.

[0121] In this design, the first connecting structure 8 is a bolt, the connecting part is a threaded rod, and the fixing part is a head. This reduces the difficulty of obtaining the first connecting structure 8, thereby improving the ease of manufacturing the grinding device.

[0122] Specifically, when it is necessary to change the angle of the fixing unit 3 relative to the base 7, the first connecting structure 8 is loosened so that the connector is disengaged from the fifth threaded hole and placed in the arc groove 307. The fixing unit 3 can rotate relative to the base 7. After the position of the fixing unit 3 is determined, the first connecting structure 8 moves to the position of the arc groove 307 corresponding to the fifth threaded hole and is threadedly connected to the fifth threaded hole until the fixing member tightly presses the fixing unit 3 onto the base 7, thereby fixing the rotation angle position of the fixing unit 3 and achieving the technical effect of improving the positional stability of the fixing unit 3.

[0123] Preferably, the polishing device includes:

[0124] The second connecting structure 9 is located on the side of the first connecting structure 8 near the inlet, or on the side of the first connecting structure 8 near the outlet 3021. The second connecting structure 9 is detachably connected to the fixing unit 3 and the base 7, so that the fixing unit 3 and the base 7 are detachably connected.

[0125] By setting the second connection structure 9, the number of connection points between the fixing unit 3 and the base 7 can be increased, thereby achieving the technical effect of improving the reliability of the rotation angle fixing of the fixing unit 3.

[0126] In this embodiment, the second connecting unit is located on the side of the first connecting structure 8 near the inlet. Alternatively, the second connecting unit may be located on the side of the first connecting structure 8 near the outlet 3021. Of course, in other embodiments, the number of second connecting structures 9 may be adjusted depending on the design of the grinding device.

[0127] Specifically, the surface of the second connecting structure 9 is provided with a second thread, and both the fixing unit 3 and the base 7 are provided with a sixth threaded hole that mates with the second thread. The threaded connection between the second connecting structure 9 and the fixing unit 3, and between the second connecting structure 9 and the base 7, improves the ease of detachable connection between the second connecting structure 9 and the fixing unit 3 and the base 7, thereby enhancing the ease of manufacturing the grinding device. Specifically, the fixing unit 3 and the base 7 can be connected first via the second connecting structure 9, but not directly tightened. Then, the rotation angle of the fixing unit 3 around the second connecting structure 9 is adjusted. Finally, the fixing unit 3 and the base 7 are connected via the first connecting structure 8, while simultaneously tightening the second connecting structure 9 with the sixth threaded hole to fix the rotation angle of the fixing unit 3.

[0128] As an alternative implementation, the two sixth threaded holes can be aligned first, then the rotation angle of the fixing unit 3 can be adjusted, then the fixing unit 3 can be connected to the base 7 through the first connecting structure 8, and finally the fixing unit 3 can be connected to the base 7 through the second connecting structure 9.

[0129] In other embodiments, depending on the design of the grinding device, only the base 7 may have a sixth threaded hole, the fixing unit 3 may have a through hole, and the second connecting structure 9 may pass through the through hole of the fixing unit 3 and connect to the sixth threaded hole. All of these are within the protection scope of this utility model.

[0130] Of course, in other embodiments, the detachable method between the fixing unit 3 and the base 7 can be adjusted. For example, multiple through holes are provided on the fixing unit 3, and an arc is formed between the multiple through holes. When the fixing unit 3 is rotated to the required angle, the first connecting structure 8 passes through the through hole corresponding to the fifth threaded hole and is threadedly connected to the fifth threaded hole, which can also achieve the fixing of the rotation angle position of the fixing unit 3.

[0131] As an alternative implementation, the grinding device may not include the base 7, and the fixing unit 3 may be detachably connected to other fixed structures, such as a wall.

[0132] Of course, in other embodiments, depending on the design of the polishing device, it may be limited to the fixing unit 3 having a second channel 304 and a third channel 305, or it may be limited to the polishing device including a base 7, all of which are within the protection scope of this utility model.

[0133] In other embodiments, depending on the design of the polishing device, the polishing device may be limited to including the limiting unit 4, or the polishing device may be limited to including the first connecting structure 8, or the polishing device may be limited to including the second connecting structure 9.

[0134] Alternatively, the grinding device may not include the second connecting structure 9.

[0135] According to an embodiment of the present invention, another aspect provides a coating system, comprising:

[0136] A wire spool is connected to one end of the workpiece 2 to be polished, and the workpiece 2 to be polished is wound on the wire spool.

[0137] The wire feeding unit is located on one side of the wire spool frame and is connected to the other end of the workpiece 2 to be polished, so as to drive the movement of the workpiece 2 to be polished through the wire feeding unit.

[0138] In this embodiment, the polishing device is located between the wire spool frame and the wire feeding unit. The other end of the workpiece 2 to be polished enters the wire feeding unit through the polishing device.

[0139] Among them, the wire spool holder and the wire feeding unit are mature technologies of the coating system, and will not be elaborated on here.

[0140] In the coating system of this embodiment, the wire feeding unit drives the workpiece 2 to be polished to detach from the wire spool holder one turn at a time. The workpiece 2 is then passed to the wire feeding unit via a polishing device. The polishing device can remove oxide film, dust, and other impurities from the surface of the workpiece 2, thereby improving the purity of the workpiece 2 and preventing sputtering, thus improving the accuracy and safety of the vapor deposition process. Simultaneously, the tilt direction of the workpiece 2 depends on the position between the wire spool holder and the wire feeding unit. The polishing device in this embodiment can adapt to workpieces 2 at various tilt angles, thereby improving the ease of use and reliability of the coating system.

[0141] Of course, in other embodiments, depending on the design of the grinding device, the grinding device may be driven by an external force to move along the length of the workpiece 2 to be ground.

[0142] In this embodiment, the wire spool is positioned below the wire feeding unit. Of course, in other embodiments, the relative positions of the wire spool and the wire feeding unit may be adjusted depending on the design of the polishing device.

[0143] In this embodiment, the coating system employs vacuum coating technology. Of course, in other embodiments, the coating technology of the coating system may be adjusted according to different application scenarios.

[0144] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
