[0037] The vacuum coating equipment is a device that vacuum coats materials through magnetron sputtering, ion etching, electron beam evaporation and other technologies. The vacuum coating equipment is provided with an electrode introduction assembly, which is used to introduce the current from the atmosphere side into the working parts in the vacuum chamber of the vacuum coating equipment. The electrode introduction assembly includes a mounting seat and a plurality of conductive electrodes. The mounting seat is generally a flange, and the plurality of electrodes are inserted into the mounting seat. After the mounting seat is installed on the vacuum coating equipment, one end of the electrode extends into the vacuum chamber of the vacuum coating equipment and is connected to the parts in the vacuum chamber, and the other end of the electrode is located outside the vacuum chamber and is connected to an external power line. The power line introduces the current of the power supply through the electrode into the working parts in the vacuum chamber, such as the electric heating wire.

[0038] The existing electrode introduction assembly has the following disadvantages: since the spacing between adjacent electrodes is very close, resulting in a very small electrical gap, when the electrodes are energized, arcs are easily generated between the connection points of each electrode and the power line, which can easily cause a short circuit and damage the equipment, resulting in poor safety.

[0039] To this end, the utility model proposes an electrode introduction component and a vacuum coating device, which can effectively solve the above problems.

[0040] Reference below Figures 1 to 4An electrode introduction assembly and a vacuum coating device according to an embodiment of the utility model are described.

[0041] The electrode introduction assembly according to the first embodiment of the utility model is applied to vacuum coating equipment, such as Figures 1 to 4 As shown, the vacuum coating device includes a mounting seat 100 , a plurality of electrodes 200 and a plurality of insulating sleeves 300 .

[0042] Among them, the mounting base 100 can be set as a flange structure to facilitate connection with the casing of the vacuum coating equipment. The mounting base 100 is provided with multiple through holes for the electrodes 200 to pass through. For example, when there are 6 electrodes 200, the mounting base 100 can be correspondingly provided with 6 through holes.

[0043] The number of electrodes 200 can be 5, 6, 7 or other suitable numbers, for example, 6 electrodes 200 are made of conductive materials such as brass to be able to conduct electricity. Multiple electrodes 200 are inserted into the mounting base 100, and one end of the electrode 200 forms a terminal 201. When the mounting base 100 is installed on the vacuum coating equipment, the terminal 201 can be located outside the vacuum chamber of the vacuum coating equipment. The terminal 201 is used to connect the power cord 202. For example, the terminal 201 and the power cord 202 can be welded.

[0044] The number of insulating sleeves 300 can be the same as the number of electrodes 200 and correspond one to one. For example, when there are 6 electrodes 200, 6 insulating sleeves 300 can be provided accordingly. The insulating sleeves 300 are made of electrically insulating material, for example, they can be made of ceramics. Multiple insulating sleeves 300 are respectively sleeved on the outside of multiple electrodes 200, and the terminal 201 is located in the insulating sleeve 300. In this way, the connection position of the terminal 201 and the power cord 202 is also located in the insulating sleeve 300, so that the insulating sleeve 300 can separate the connection positions of the terminal 201 of the multiple electrodes 200 from the power cord 202.

[0045] In the present invention, after the mounting base 100 is installed on the vacuum coating equipment, the terminal 201 of the electrode 200 is located outside the vacuum chamber of the vacuum coating equipment, and the terminal 201 is used to connect with the external power line 202. The end of the electrode 200 away from the terminal 201 extends into the vacuum chamber to be connected with the working parts in the vacuum chamber. According to the electrode introduction assembly of the embodiment of the present invention, since the outer side of each electrode 200 is provided with an insulating sleeve 300, and the terminal 201 of the electrode 200 is located in the insulating sleeve 300, the insulating sleeve 300 can separate the connection position of the terminal 201 of each electrode 200 from the power line 202, which greatly increases the electrical gap, thereby reducing the generation of arcs and effectively improving the safety performance of the vacuum coating equipment. In addition, the insulating sleeve 300 can prevent the connection position between the terminal 201 of each electrode 200 and the power line 202 from being exposed, thereby not only reducing the rust and corrosion of the connection position between the terminal 201 of the electrode 200 and the power line 202, but also extending the service life and making it neater and more beautiful.

[0046] refer to Figures 1 to 4 As shown, in some embodiments of the present invention, the electrode introduction assembly further includes a protective sleeve 400, one end of which is connected to the mounting seat 100, and all the insulating sleeves 300 are located in the protective sleeve 400. For example, a first annular flange 401 may be provided at one end of the protective sleeve 400 close to the mounting seat 100, and the first annular flange 401 may extend along the circumference of the protective sleeve 400, and a plurality of fasteners may be provided between the first annular flange 401 and the mounting seat 100.

[0047] In this embodiment, the protective cover 400 is provided to protect all the insulating covers 300 and the electrodes 200, reduce the damage to the insulating covers 300 and the electrodes 200, and extend the service life of the insulating covers 300 and the electrodes 200. Secondly, the protective cover 400 can be made of an electrically insulating material, which can further reduce leakage and short circuit, and improve safety. In addition, the insulating cover 300 is not exposed to the outside, and is also more neat and beautiful.

[0048] refer to Figures 1 to 4As shown, in some embodiments of the present invention, the electrode introduction assembly further includes a cover body 500, which is connected to the end of the protective sleeve 400 away from the mounting seat 100 to cover the protective sleeve 400, and the cover body 500 is provided with a clearance hole 501 for the power cord 202 to pass through. For example, the end of the protective sleeve 400 away from the mounting seat 100 may be provided with a second annular flange 402, the second annular flange 402 may extend along the circumference of the protective sleeve 400, and a plurality of fasteners may be provided between the second annular flange 402 and the cover body 500. The number of the clearance holes 501 on the cover body 500 may be the same as the number of the electrodes 200 and correspond one to one, and the power cord 202 is passed through the corresponding clearance holes 501.

[0049] In this embodiment, the cover 500 is provided to further protect all the insulating sleeves 300 and the electrodes 200, further reduce the damage to the insulating sleeves 300 and the electrodes 200, and extend the service life of the insulating sleeves 300 and the electrodes 200. Secondly, it can also reduce the entry of external rainwater and dust into the protective sleeve 400. In addition, the cover 500 can also be made of an electrically insulating material, which can further reduce leakage and short circuit, and improve safety.

[0050] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the cover 500 and the mounting seat 100 respectively abut against the two ends of the axial direction of the insulating sleeve 300. Such a configuration can prevent the insulating sleeve 300 from moving randomly along its own axial direction, thereby making the insulating sleeve 300 have a better protective effect on the connection position between the terminal 201 of the electrode 200 and the power line 202.

[0051] refer to Figures 2 to 4 As shown, in some embodiments of the present invention, the mounting base 100 includes a flange 101 and an insulating column 102, the flange 101 is sleeved on the outside of the insulating column 102, and a plurality of electrodes 200 are inserted through the insulating column 102. For example, the flange 101 may be a KF flange, the flange 101 is used to connect with the flange structure on the casing of the vacuum coating equipment, the flange 101 is provided with a sleeve hole and sleeved on the outside of the insulating column 102 through the sleeve hole, the insulating column 102 may be connected to the flange 101 by bonding, welding, threading or other suitable methods, the insulating column 102 is made of an electrical insulating material, the insulating column 102 is provided with a plurality of through holes, and the electrodes 200 are inserted through the corresponding through holes.

[0052] In this embodiment, the mounting base 100 includes a flange 101 and an insulating column 102. The flange 101 is convenient for connection with the housing of the vacuum coating equipment, and the insulating column 102 is convenient for the electrode 200 to be inserted and has electrical insulation, which can reduce leakage and short circuit phenomena and improve safety.

[0053] refer to Figures 1 to 4As shown, in some embodiments of the present invention, the flange 101 is provided with an annular groove 103 surrounding the insulating column 102, the protective sleeve 400 abuts against the bottom surface of the annular groove 103, and is connected to the flange 101 by fasteners, and the inner side wall of the protective sleeve 400 fits the outer side wall of the insulating column 102. For example, the end of the protective sleeve 400 close to the mounting seat 100 may be provided with a first annular flange 401, the first annular flange 401 may extend along the circumference of the protective sleeve 400, the first annular flange 401 abuts against the bottom surface of the annular groove 103, and is connected to the flange 101 by fasteners, the outer side wall of the first annular flange 401 may fit with the side wall of the annular groove 103, and the inner side wall of the protective sleeve 400 fits with the outer side wall of the insulating column 102. In this embodiment, such a configuration not only makes the connection of the protective sleeve 400 more stable, but also makes the sealing better, reducing the leakage of the vacuum chamber of the vacuum coating equipment.

[0054] refer to Figures 1 to 4 As shown, in some embodiments of the present invention, the side wall of the annular groove 103 is provided with an annular depression 104 surrounding the protective sleeve 400, and the electrode introduction assembly further includes a seal 600, and the seal 600 includes a center ring 601 and a sealing ring 602, the center ring 601 abuts against the side wall of the annular groove 103, and the sealing ring 602 is sleeved on the outside of the center ring 601 and located in the annular depression 104. For example, an axial end of the outer wall of the center ring 601 can abut against the side wall of the annular groove 103, and an annular limiting portion can be provided at the middle position of the outer wall of the center ring 601, and the annular limiting portion can be located in the annular depression 104, and the outer wall of the annular limiting portion can be provided with an annular recess, and the sealing ring 602 is sleeved on the outside of the annular limiting portion and partially embedded in the annular recess.

[0055] In this embodiment, a sealing ring 602 is arranged in the annular sink 104, so that when the flange 101 is connected to other flange structures on the vacuum coating equipment, a sealing effect can be achieved to reduce air leakage in the vacuum chamber of the vacuum coating equipment. A center ring 601 is arranged, the center ring 601 abuts against the side wall of the annular groove 103, and the sealing ring 602 is sleeved on the outside of the center ring 601, so that the sealing ring 602 can be positioned to prevent the sealing ring 602 from moving at will, thereby achieving a better sealing effect.

[0056] In some embodiments of the present invention, the insulating sleeve 300 is made of ceramic. The insulating sleeve 300 is made of ceramic, which not only has good electrical insulation effect, but also has good fireproof, moisture-proof and corrosion-proof effects. In addition, it has high structural strength, good anti-aging performance and long service life.

[0057] It should be noted that the insulating column 102 may also be made of ceramics. In addition, the insulating sleeve 300 and the insulating column 102 may also be made of other electrically insulating materials, such as electrically insulating rubber, which will not be described in detail here.

[0058] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the terminal 201 is located in the middle of the length direction of the insulating sleeve 300. In this way, the connection position of the terminal 201 of the electrode 200 and the power line 202 is approximately in the middle of the length direction of the insulating sleeve 300, thereby further improving the separation effect of the insulating sleeve 300 and further increasing the electrical gap, thereby further reducing the generation of arcs and further improving the safety performance of the vacuum coating equipment.

[0059] refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, there is a gap between the insulating sleeve 300 and the electrode 200, and there is a gap between the insulating sleeve 300 and the power line 202. Such a configuration is not only convenient for installing the insulating sleeve 300, but also convenient for removing the insulating sleeve 300 when the insulating sleeve 300, the electrode 200, or the power line 202 needs to be repaired or replaced.
