[0033] Example 1

[0034] like Figures 1 to 4 As shown, a positive electrode seat for evaporation coating described in one embodiment of the utility model includes a seat body 1, the seat body 1 includes a base 101 and a seat head 102 arranged at the second end of the base 101, the outer periphery of the base 101 is sleeved with an insulating sleeve 2, the outer periphery of the seat head 102 is sleeved with a retaining ring 3, and an insulating tube 4 is arranged between the insulating sleeve 2 and the retaining ring 3.

[0035] In this embodiment, the positive electrode of the power supply and the evaporation boat 10 are connected through the pole seat body 1, the base 101 is connected to the positive electrode of the power supply, and the pole seat head 102 is connected to the evaporation boat 10, so the two have good conductivity. Usually, the base 101 and the pole seat head 102 are made of metal materials with good electrical conductivity, such as copper or aluminum. The insulating sleeve 2 and the insulating tube 4 are both made of materials with good insulation. On the one hand, the pole seat body 1 can be insulated and protected, and the pole seat body 1 and the evaporation tank 11 are isolated to prevent the short circuit between the evaporation tank 11 and the pole seat body 1. On the other hand, the evaporation material can be prevented from being deposited on the pole seat body 1, thereby preventing the short circuit between the evaporation tank 11 and the pole seat body 1. The retaining ring 3 is made of insulating material and is located on the inner side of the evaporation tank 11. The retaining ring 3 is sleeved on the outer periphery of the pole seat head 102 to prevent the evaporation material from falling to the connection between the pole seat body 1 and the evaporation tank 11 during the evaporation process, thereby preventing the short circuit between the evaporation tank 11 and the pole seat body 1.

[0036] In practical applications, the lengths and inner dimensions of the insulating tube 4 , the insulating sleeve 2 and the retaining ring 3 should be set according to the dimensions of the pole seat body 1 to ensure that they can effectively prevent a short circuit between the evaporation tank 11 and the pole seat body 1 .

[0037] like Figure 4 As shown, in a preferred embodiment, the second end of the pole seat head 102 is provided with an evaporation boat clamping platform 5 for supporting one side of the evaporation boat 10, and the evaporation boat clamping platform 5 is integrally formed with the pole seat head 102. In this embodiment, the evaporation boat clamping platform 5 and the pole seat head 102 are integrally formed, so that the structure of the entire pole seat is more stable. Compared with manufacturing and assembling the evaporation boat clamping platform 5 and the pole seat head 102 separately, the integrated design reduces the manufacturing steps, does not require installation and matching, avoids misalignment and improper matching during the installation process, and improves production efficiency.

[0038] In a preferred embodiment, the insulating sleeve 2 is a polytetrafluoroethylene tube. The polytetrafluoroethylene tube is a high-performance insulating material with excellent electrical properties and chemical stability. First, the polytetrafluoroethylene tube has good insulation properties. Its high insulation resistance and low dielectric loss factor can effectively prevent short circuits, and can prevent short circuits between the pole seat body 1 and the evaporation tank 11, thereby improving the efficiency and quality of the coating. Secondly, the polytetrafluoroethylene tube has excellent high temperature resistance. During the evaporation coating process, the temperature is usually very high, and the polytetrafluoroethylene tube can maintain stable performance under high temperature conditions, preventing material deformation and performance degradation caused by temperature increases. In addition, the polytetrafluoroethylene tube also has excellent chemical stability. During the evaporation coating process, various chemicals and corrosive gases may be exposed. The polytetrafluoroethylene tube has good resistance to most chemicals, can effectively prevent chemical corrosion, and maintain its original electrical and physical properties. Due to its excellent chemical stability and high temperature resistance, the polytetrafluoroethylene tube has a long life, can maintain stable performance during long-term evaporation coating, and reduces the frequency of replacement and maintenance costs. Finally, the polytetrafluoroethylene tube can be in the form of a straight tube or a curved tube, which can be directly sleeved on the outer periphery of the base 101, and is easy and quick to install.

[0039] In a preferred embodiment, the insulating tube 4 is a mica tube. In this embodiment, the insulating tube 4 is a mica tube, which can further enhance the stability and safety of the evaporation coating process. First, the mica tube has excellent high-temperature insulation performance. In the evaporation coating process, the operating temperature is usually very high. The mica tube has excellent high-temperature insulation performance, which can maintain stable electrical properties in a high-temperature environment and avoid material deformation and performance degradation caused by temperature increase. Secondly, the mica tube also has good thermal insulation performance. In the evaporation coating process, due to the need to heat and evaporate materials, the equipment usually needs to operate in a high-temperature environment. The mica tube has excellent thermal insulation performance, which can effectively prevent the transfer of heat and keep the temperature inside the equipment stable, thereby improving the efficiency and effect of evaporation coating. In addition, the mica tube also has excellent corrosion resistance. In the evaporation coating process, it may be exposed to various chemicals and corrosive gases. The mica tube has good resistance to most chemicals, which can effectively prevent chemical corrosion and maintain its original electrical and physical properties.

[0040] like Figure 4 As shown, in a preferred embodiment, a cooling water pipeline 111 is arranged inside the pole head 102 and the base 101, the water inlet and the water outlet of the cooling water pipeline 111 are arranged at the first end of the base 101, and the base 101 is respectively provided with cooling water pipe interfaces 112 at the water inlet and the water outlet.

[0041] In this embodiment, the heat inside the device can be effectively transferred to the cooling water system by the cooling water pipeline 111 disposed inside the pole seat head 102 and the base 101, thereby preventing the pole seat body 1, the insulating ring, the insulating tube 4 and the retaining ring 3 from being deformed, the performance is degraded or the equipment is damaged due to the excessive temperature inside the equipment, thereby maintaining the stability of the equipment and extending its service life. Secondly, the water inlet and the water outlet of the cooling water pipeline 111 are disposed at the first end of the base 101, so that the cooling water can enter and flow out of the device more conveniently. At the same time, the cooling water pipe interfaces 112 are respectively disposed at the water inlet and the water outlet of the base 101, which facilitate the connection of the cooling pipeline.

[0042] like Figure 4 As shown, in a preferred embodiment, the first end of the retaining ring 3 is provided with an annular groove 301, and the second end of the insulating tube 4 is arranged in the annular groove 301. This further prevents the evaporation material from falling onto the connection between the pole seat body 1 and the evaporation groove 11 during the evaporation process, and prevents a short circuit between the evaporation groove 11 and the pole seat body 1.

[0043] Example 2

[0044] like Figures 5 to 7 As shown, the difference from Example 1 is that the evaporation boat clamping platform 5 is detachably connected to the pole seat head 102. The evaporation boat clamping platform 5 is easy to disassemble and can be quickly replaced, thereby improving production efficiency.

[0045] A support seat 103 is provided at the second end of the pole seat head 102, and the support seat 103 includes a first contact surface 104 and a second contact surface 105 that are in contact with the evaporation boat clamping table 5, the first contact surface 104 is provided with a first threaded hole 106, the second contact surface 105 is provided with a first through hole 107, the evaporation boat clamping table 5 is provided with a second through hole 501 corresponding to the first threaded hole 106, and a second threaded hole 502 corresponding to the first through hole 107, the first through hole 107 is penetrated by a first fastener 6 threadedly connected to the second threaded hole 502, and the second through hole 501 is penetrated by a second fastener 7 threadedly connected to the first threaded hole 106.

[0046] In the existing evaporation method, the connection between the electrode and the evaporation boat 10 is always in a high temperature environment during the power-on process, which may cause cracking. Replacing a new electrode requires replacing the cooling water pipe, and disassembling the electrode is very cumbersome and inefficient.

[0047] In this embodiment, the first fastener 6 and the second fastener 7 are both screws, and can also be fasteners such as bolts and pins, that is, the evaporation boat clamping platform 5 is connected to the pole seat head 102 by screws, so that the connection between the evaporation boat clamping platform 5 and the pole seat head 102 is stable and reliable, and it is easy to disassemble and replace the evaporation boat clamping platform 5 without disassembling the entire positive pole seat. Due to the detachable design, the replacement and maintenance of the parts are faster and more convenient, so the maintenance and replacement time can be shortened, and the production efficiency can be improved.

[0048] Example 3

[0049] like Figure 8 and Fig. 9 As shown, the difference from Example 2 lies in that a clamping block 108 is provided at the second end of the pole seat head 102, a third threaded hole 109 is provided on the top surface of the clamping block 108, a fourth threaded hole 110 is provided on the end surface of the clamping block 108, a clamping groove 503 engaged with the clamping block 108, a third through hole 504 corresponding to the third threaded hole 109, a fourth through hole 505 corresponding to the fourth threaded hole 110 is provided on the evaporation boat clamping table 5, a third fastener 8 threadedly connected to the third threaded hole 109 is penetrated through the third through hole 504, and a fourth fastener 9 threadedly connected to the fourth threaded hole 110 is penetrated through the fourth through hole 505.

[0050] In this embodiment, when connecting the evaporation boat clamping platform 5 and the pole head 102, the clamping block 108 is engaged with the clamping slot 503, and the third fastener 8 and the fourth fastener 9 are both screws, and can also be fasteners such as bolts and pins. That is, the evaporation boat clamping platform 5 and the pole head 102 are connected by screws. The connection between the evaporation boat clamping platform 5 and the pole head 102 is stable and reliable, and is easy to install and disassemble.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
