Description

Technical Field

[0001] The utility model relates to the technical field of evaporation boats, in particular to a trapezoidal ceramic conductive evaporation boat. Background Art

[0002] Evaporation boat is a general term for all evaporation vessels. Its composition formula varies depending on the purpose of use. The materials involved include boron nitride, titanium diboride, aluminum nitride, aluminum oxide, zirconium oxide, silicon carbide, silicon nitride and other metal and non-metal compounds. The trapezoidal ceramic conductive evaporation boat is shaped like a trapezoid and is made of ceramic material. It is widely used in vacuum coating of various metals, compounds and other materials, such as in optical lenses, decorative coating and other fields.

[0003] The prior art includes a utility model with publication number CN202347084U. The utility model relates to an evaporation boat, specifically a trapezoidal conductive ceramic evaporation boat, including a boat body, a material groove is provided on the upper part of the boat body, and the characteristic is that the lower part of the boat body is a trapezoidal body which is wide at the top and narrow at the bottom. The utility model has a simple structure and is easy to manufacture. The unique trapezoidal design makes the evaporation boat dissipate heat more evenly, thereby ensuring the effective extension of the service life, and solves the problem that a part of the boat body of the existing evaporation boat evaporates and leaves holes during use, so that the molten aluminum to be evaporated will penetrate into these holes, reducing the resistivity of the material, causing local uneven heat dissipation, causing material sputtering and loss during the evaporation process, making the coating uneven and reducing the service life.

[0004] In daily work, it is found that the existing trapezoidal ceramic conductive evaporation boat has a single structure as a whole. However, after the trapezoidal ceramic conductive evaporation boat has been in contact with the electrode for a long time, the two ends of the trapezoidal ceramic conductive evaporation boat are very likely to be worn, damaged or have poor contact, resulting in the trapezoidal ceramic conductive evaporation boat being unable to be used normally. It is necessary to replace it as a whole, which increases the cost. As a result, once the contact end of the existing trapezoidal ceramic conductive evaporation boat with the electrode is damaged, it is necessary to replace the entire boat. Utility Model Content

[0005] The utility model aims to solve the defect in the prior art that once the contact end of the trapezoidal ceramic conductive evaporation boat and the electrode is damaged, the whole needs to be replaced, and the trapezoidal ceramic conductive evaporation boat is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a trapezoidal ceramic conductive evaporation boat, comprising a boat body and a replacement device, the upper part of the boat body is rectangular, and the lower part is trapezoidal, a material discharge groove is arranged on the surface of the boat body, and the replacement device is arranged on the surface of the boat body, and the replacement device comprises a replacement block, and there are two replacement blocks, and the two replacement blocks are respectively arranged on both sides of the boat body, and plug blocks are fixedly connected to the two side surfaces of the replacement block, and a mounting groove is opened on the side surface of the boat body close to the replacement block, and the plug block is arranged in a T shape, and the mounting groove matches the shape of the plug block to accommodate the plug block, and a positioning component is arranged on the surface of the boat body, through the above-mentioned components, the replacement block and the plug block are made of the same material as the boat body, and the replacement block is used to contact the electrode. When the replacement block is damaged, there is no need to replace the entire boat body, and only the replacement block needs to be pushed, and the T-shaped plug block is removed from the mounting groove, and the damaged replacement block can be replaced separately and can continue to be used, saving costs.

[0007] Preferably, two gaskets are fixedly connected to the surface of the plug block, and the two gaskets are arranged in an L shape. Through the above components, after the plug block is inserted into the installation groove, the plug block will cooperate with the gasket to squeeze into the installation groove on the surface of the boat body, making its installation more stable and not shaking.

[0008] Preferably, the two gaskets are made of graphite material. Through the above components, the gaskets made of graphite material can better resist high temperatures and conduct electricity.

[0009] Preferably, the positioning assembly includes a block, four slide grooves are provided on the surface of the boat body, and there are four blocks. The four blocks are respectively slidably connected to the inner walls of the slide grooves, and a slot is provided on the surface of the plug block. The block is plugged into the inner wall of the slot. Through the above components, the block can be slid in the slide groove so that the block is inserted into the slot on the surface of the plug block, thereby improving the overall stability after installation.

[0010] Preferably, a protective device is provided on the surface of the boat body, and the protective device includes a protective plate, which is arranged above the boat body, and the surface of the protective plate is provided with two sliding holes, the inner walls of the sliding holes are slidably connected with a clamping plate, and the side of the clamping plate corresponding to the inner wall of the sliding hole is fixedly connected with a spring. Through the above components, when protection is needed, the elastic force of the spring can be used to control the clamping of the clamping plate and the inner wall of the material discharge trough on the surface of the boat body, so as to limit the position of the protective plate. The protective plate can protect the boat body and the material discharge trough when not in use, and can reduce the entry of impurities, which causes additional cleaning during use.

[0011] Preferably, a push block is fixedly connected to the surface of the splint, and the size of the push block is larger than the size of the sliding hole, so the sliding hole can be blocked. By setting the push block, the push block can drive the splint to move, thereby facilitating operation. At the same time, the size of the push block is similar to the size of the sliding hole, which can have the effect of blocking the sliding hole.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] In the utility model, by providing a replacement device, the replacement head can be used to continue to contact the electrode, so as to heat the boat body. When the replacement head is damaged due to long-term contact with the electrode, the plug on the surface of the replacement head can be removed from the installation groove for replacement. By providing a replacement device, when the trapezoidal ceramic conductive evaporation boat contacts the electrode, when the contact part is worn, damaged or has poor contact due to long-term use, this local part can be easily replaced without replacing the entire evaporation boat, thereby reducing costs.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: a trapezoidal ceramic conductive evaporation boat, comprising a boat body 1 and a replacement device 3, the upper part of the boat body 1 is rectangular, the lower part is trapezoidal, a discharge trough 2 is arranged on the surface of the boat body 1, the replacement device 3 is arranged on the surface of the boat body 1, and a protective device 4 is arranged on the surface of the boat body 1.

[0023] The specific settings and functions of the replacement device 3 and the protective device 4 are described in detail below.

[0024] Specifically, the replacement device 3 includes a replacement block 31. There are two replacement blocks 31, which are respectively arranged on both sides of the boat body 1. The two side surfaces of the replacement block 31 are fixedly connected with plug blocks 32. A mounting groove 35 is provided on the side surface of the boat body 1 close to the replacement block 31. The plug block 32 is arranged in a T shape. The mounting groove 35 matches the shape of the plug block 32 so as to accommodate the plug block 32. A positioning component 33 is provided on the surface of the boat body 1.

[0025] In this embodiment, the replacement block 31 and the plug block 32 are made of the same material as the boat body 1. The replacement block 31 is used to contact the electrode. When the replacement block 31 is damaged, there is no need to replace the entire boat body 1. Only the replacement block 31 needs to be pushed and the T-shaped plug block 32 needs to be removed from the installation groove 35. The damaged replacement block 31 can be replaced alone and the boat body 1 can continue to be used, which saves costs.

[0026] Specifically, two gaskets 34 are fixedly connected to the surface of the insert block 32 , and the two gaskets 34 are arranged in an L shape.

[0027] In this embodiment, after the insert block 32 is inserted into the installation groove 35, the insert block 32 cooperates with the gasket 34 to be squeezed into the installation groove 35 on the surface of the boat body 1, so that the installation is more stable and does not shake.

[0028] Specifically, the two gaskets 34 are made of graphite material. The gaskets 34 made of graphite material can better withstand high temperatures and conduct electricity.

[0029] Specifically, the positioning assembly 33 includes a block 331, four slide grooves 332 are provided on the surface of the boat body 1, and there are four block 331. The four block 331 are respectively slidably connected to the inner walls of the slide groove 332. A slot 333 is provided on the surface of the plug block 32. The block 331 is plugged into the inner wall of the slot 333. The block 331 can be slid in the slide groove 332 so that the block 331 is inserted into the slot 333 on the surface of the plug block 32, thereby improving the overall stability after installation.

[0030] Specifically, the protective device 4 includes a protective plate 41, which is arranged above the boat body 1. Two sliding holes 45 are opened on the surface of the protective plate 41. The inner wall of the sliding hole 45 is slidably connected with a clamping plate 43. The side of the clamping plate 43 corresponding to the inner wall of the sliding hole 45 is fixedly connected with a spring 44.

[0031] In this embodiment: when protection is needed, the elastic force of the spring 44 can be used to control the clamping of the clamping plate 43 and the inner wall of the discharge trough 2 on the surface of the boat body 1, so as to limit the position of the protective plate 41. The protective plate 41 can protect the boat body 1 and the discharge trough 2 when not in use, and can reduce the entry of impurities, which requires additional cleaning during use.

[0032] Specifically, a push block 42 is fixedly connected to the surface of the clamping plate 43 . The size of the push block 42 is larger than the size of the sliding hole 45 , and the sliding hole 45 can be covered.

[0033] In this embodiment, the push block 42 can drive the clamping plate 43 to move, thereby facilitating the operation. At the same time, the size of the push block 42 and the size of the sliding hole 45 can have the effect of shielding the sliding hole 45.

[0034] Working principle: By setting up the replacement device 3, the replacement head can be used to continue to contact the electrode, so as to heat the boat body 1. When the replacement head is damaged or has poor contact due to long-term contact with the electrode, the replacement head can be removed for replacement. When replacing, first push the block 331 in the positioning component 33 to move the block 331 out of the slot 333 on the surface of the plug block 32. After the block 331 is completely moved into the slide groove 332, push the replacement head upward to move the plug block 32 on the surface of the replacement head out of the mounting groove 35, and the replacement can be achieved. By setting up the replacement device 3, when the trapezoidal ceramic conductive evaporation boat is in contact with the electrode, if the contact part is worn, damaged or has poor contact due to long-term use, this local component can be easily replaced without replacing the entire evaporation boat, thereby reducing costs.

[0035] By setting the protective device 4, when protection is needed, the push block 42 and the clamping plate 43 are pushed, the spring 44 is stressed, and then the protective plate 41 is covered on the boat body 1, the push block 42 is loosened, the spring 44 releases the elastic force, and the elastic force of the spring 44 cooperates with the clamping plate 43 to clamp the clamping plate 43 in the inner wall of the discharge trough 2 to achieve the positioning of the protective plate 41. The protective plate 41 can protect the boat body 1 and the discharge trough 2, thereby blocking the entry of impurities and reducing the need for additional cleaning during use.
