Description

Technical Field

[0001] This utility model relates to the field of vacuum evaporation technology, specifically to an evaporation boat for reducing surface deposits. Background Technology

[0002] In vacuum evaporation deposition of functional current collectors, metal wires are placed on an evaporation boat. These wires are heated to melt and vaporize into metal vapor, which then adheres to the substrate to form the functional current collector. Over prolonged use, the evaporation boat used for vacuum evaporation deposition of functional current collectors will accumulate a large amount of deposits. These deposits gradually build up from the outermost edge of the evaporation boat, forming a large deposit area. This results in a decreasing evaporation area for the molten metal, and the mixing of deposits and molten metal splashes affects the quality of both the evaporation boat and the functional current collector. Deposits have a significant impact on the quality of high-quality functional current collector products; therefore, the evaporation boat needs to be replaced when deposits accumulate to a certain level, reducing its lifespan.

[0003] Currently, the main method for cleaning evaporation boat sediments is manual cleaning, which involves scraping the sediments off the evaporation boat directly with iron sheets or other materials. This manual cleaning method is difficult, can easily damage the evaporation boat, has poor cleaning results, and is time-consuming, labor-intensive, and increases costs. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing an evaporation boat that reduces surface deposits.

[0005] The technical solution provided by this utility model is:

[0006] An evaporation boat for reducing surface deposits includes an evaporation boat body, the evaporation boat body being formed by interlocking a first interlocking structure and a second interlocking structure;

[0007] The first insertion structure includes an evaporation platform, an evaporation base, and one side of an evaporation boat. The evaporation platform is disposed on the evaporation base, and the sides of the evaporation platform and the evaporation base are connected to one side of the evaporation boat.

[0008] The second interlocking structure includes a deposition platform and the other side of the evaporation boat, wherein the deposition platform is connected to the side of the other side of the evaporation boat.

[0009] The evaporation base protrudes from the evaporation platform to form a step. When the first and second interlocking structures are interlocked, the deposition platform can be installed on the step, and the height of the installed deposition platform is lower than that of the evaporation platform, so that a deposition groove is formed between the evaporation platform and the edge of the deposition platform.

[0010] To optimize the above technical solution, the specific measures also include:

[0011] The evaporation platform is located in the middle of the evaporation base, and the evaporation base protrudes symmetrically from the evaporation platform, forming front and rear steps respectively; two deposition platforms are symmetrically arranged on the other side of the evaporation boat, corresponding to the front and rear steps respectively.

[0012] Furthermore, the second insertion structure also includes a deposition stage baffle, which is located next to the deposition stage and is higher than the deposition stage.

[0013] Furthermore, the evaporation platform and the deposition tank are adjacent to each other in an arc shape.

[0014] As a preferred embodiment, the evaporation platform and the deposition tank are provided with spaced-apart drainage ports.

[0015] Furthermore, the surface of the deposition stage is provided with a protective layer.

[0016] As a preferred embodiment, the protective layer is a ceramic layer.

[0017] Furthermore, one side of the evaporation boat and the other side of the evaporation boat have a symmetrical structure.

[0018] Furthermore, one side and the other side of the evaporation boat are higher than the edge of the deposition platform.

[0019] As a preferred embodiment, the first mating structure is an integral structure; the second mating structure is an integral structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The evaporation boat of this invention reduces surface deposits by using a deposition tank set on the outside of the evaporation platform. This allows impurities and deposits continuously formed during the metal wire evaporation process to flow into the deposition tanks on both sides by gravity, thus preventing deposits from remaining in the evaporation area and affecting the metal liquid spreading area, which in turn affects evaporation stability and evaporation efficiency. The removal of deposits also avoids the impact of the mixture of deposits and metal liquid splashing during the evaporation process on the quality of the evaporation boat and the functional current collector.

[0022] This invention, by setting up a first interlocking structure and a second interlocking structure that can be combined to form an evaporation boat, makes the cleaning of sediments more convenient and thorough, and the cleaning process does not affect the quality of the evaporation area of ​​the evaporation boat.

[0023] This invention can significantly extend the service life of the evaporation boat. Attached Figure Description

When the first insertion structure 1 and the second insertion structure 2 are inserted, the deposition platform 6 can be installed on the step 8. After installation, the height of the deposition platform 6 is lower than that of the evaporation platform 3, so that a deposition groove 13 is formed between the evaporation platform 3 and the edge 9 of the deposition platform.

[0038] In some embodiments, the evaporation platform 3 is located in the middle of the evaporation base 4, and the evaporation base 4 protrudes symmetrically from the evaporation platform 3, forming front and rear steps 8 respectively; two deposition platforms 6 are symmetrically provided on the other side 7 of the evaporation boat, corresponding to the front and rear steps 8 respectively.

[0044] In some embodiments, the first mating structure 1 and the second mating structure 2 are integral structures, which facilitates overall use.

[0045] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the following:

[0046] Example 1

[0047] like Figure 1-4As shown, an evaporation boat is formed by interlocking a first interlocking structure 1 and a second interlocking structure 2. The evaporation platform 3 of the first interlocking structure 1 is located on the evaporation base 4, and the sides of the evaporation platform 3 and the evaporation base 4 are connected to one side 5 of the evaporation boat. The deposition platform 6 of the second interlocking structure 2 is connected to the side of the other side 7 of the evaporation boat. The evaporation base 4 protrudes from the evaporation platform 3 to form a step 8. When the first interlocking structure 1 and the second interlocking structure 2 are interlocked, the deposition platform 6 is fitted and installed on the step 8, and the height of the installed deposition platform 6 is lower than that of the evaporation platform 3, so that a deposition groove 13 is formed between the evaporation platform 3 and the edge 9 of the deposition platform. In this embodiment, the evaporation base 4 has two steps 8 protruding from the evaporation platform 3 at the front and back, respectively. Two deposition platforms 6 are provided on the other side 7 of the evaporation boat.

The metal wire to be heated and melted is placed on the evaporation platform 3. The heated and molten metal is deposited onto the upper base film through evaporation. During this process, impurities and deposits continuously formed flow into the deposition tanks 13 on both sides by gravity, preventing deposits from remaining in the evaporation area and affecting the metal liquid spreading area. After evaporation, the first insertion structure 1 and the second insertion structure 2 are separated, and the deposits on the deposition platforms 6 are cleaned, thus avoiding any adverse effects on the evaporation platform 3. A protective layer 12, such as a high-temperature resistant ceramic layer, is provided on the surface of the deposition platforms 6, making cleaning easier and more thorough.

[0048] Example 2
