Description

Technical Field

[0001] This utility model relates to the field of graphite boat technology, specifically to a combined graphite boat locking point. Background Technology

[0002] With the rapid development of the photovoltaic industry, silicon wafer coating technology plays a crucial role in the manufacturing of solar cells. During silicon wafer coating, the graphite boat serves as a key tool for supporting the silicon wafer, and the graphite boat anchor points are important components within the graphite boat used to fix the position of the silicon wafer. Their design and materials have a decisive impact on the stability of the silicon wafer and the coating effect.

[0003] Because the material of the traditional graphite boat clamps is the same as the graphite boat material—graphite—and the hardness of graphite is much lower than that of the silicon wafer, wear grooves are prone to appear during long-term use, especially at the contact points with the bottom of the silicon wafer. These grooves not only affect the stability of the silicon wafer but also cause problems such as jamming, severely impacting the coating quality. Furthermore, due to severe wear, the graphite boat clamps have a short service life and require frequent replacement, which increases production downtime and incurs significant production costs.

[0004] Therefore, there is an urgent need for a new type of graphite boat locking structure that can maintain the excellent properties of graphite materials, solve the wear problem, extend service life, and reduce production costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a combined graphite boat clamping point, which solves the technical problem of high production costs caused by frequent replacement of existing graphite boat clamping points due to wear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a combined graphite boat locking point, including a connector, a positioning component, a first fixing component, and a second fixing component. The positioning component is detachably sleeved on the connector, and the first and second fixing components are detachably covered at both ends of the connector, with the positioning component located between the first and second fixing components. The connector, the positioning component, and the first fixing component form a first positioning groove, and the connector, the positioning component, and the second fixing component form a second positioning groove. The positioning component, the first fixing component, and the second fixing component are all made of graphite material, and the connector is made of a wear-resistant material.

[0008] In one possible implementation, the connector includes a connector body and positioning posts respectively disposed at both ends of the connector body, wherein both the first fixing member and the second fixing member are provided with positioning through holes;

[0009] The first fixing member and the second fixing member are detachably connected to the connecting member by means of the positioning pin being inserted into the positioning through hole.

[0010] In one possible implementation, both the first fixing member and the second fixing member are provided with positioning grooves, and the two ends of the connector are respectively engaged with the positioning grooves.

[0011] In one possible implementation, the first fastener and the second fastener are arranged symmetrically.

[0012] In one possible implementation, the area where the connector contacts the silicon wafer is an arc surface.

[0013] In one possible implementation, the first or second fastener includes a fastener body and an engaging portion connected to each other, the engaging portion being located on the outer ring of the fastener body.

[0014] In one possible implementation, the first fixing member, the second fixing member, and the positioning member are all chamfered.

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses a modular design for the graphite boat locking point. The positioning component is detachably fitted onto the connector, and the first and second fixing components are detachably mounted on both ends of the connector. This design allows operators to replace only the damaged parts rather than the entire graphite boat locking point, thereby increasing the replaceability of vulnerable points. While maintaining the graphite material of the positioning component, the first fixing component, and the second fixing component, the material of the connector is replaced with a wear-resistant material. This makes the connector, which is in direct contact with the silicon wafer, less prone to wear and has a longer service life. This improves the overall lifespan of the graphite boat locking point and reduces the number of times the graphite boat locking point needs to be replaced throughout its lifespan, thus reducing production costs. This solves the technical problem of high production costs caused by frequent replacements of existing graphite boat locking points due to wear. Furthermore, replacing only the material of the connector reduces the risk of abnormal coating caused by changes in the electric field due to the new material, thereby minimizing the impact on the performance of the graphite boat and even the silicon wafer coating process.

[0023] like Figure 1As shown, this utility model provides a combined graphite boat locking point 1, including a connector 11, a positioning member 12, a first fixing member 13, and a second fixing member 14. The positioning member 12 is detachably sleeved on the connector 11. The first fixing member 13 and the second fixing member 14 are detachably covered at both ends of the connector 11, with the positioning member 12 located between the first fixing member 13 and the second fixing member 14. The connector 11, the positioning member 12, and the first fixing member 13 form a first positioning groove 15, and the connector 11, the positioning member 12, and the second fixing member 14 form a second positioning groove 16. The first positioning groove 15 and the second positioning groove 16 are used to position the silicon wafer, fixing its position within the graphite boat. The positioning member 12, the first fixing member 13, and the second fixing member 14 are all made of graphite, and the connector 11 is made of a wear-resistant material.

[0024] This invention utilizes a modular design for the graphite boat locking point. Positioning element 12 is detachably mounted on connector 11, while first fixing element 13 and second fixing element 14 are detachably mounted on both ends of connector 11. This design allows operators to replace only damaged components, rather than the entire graphite boat locking point, increasing the replaceability of vulnerable points. While maintaining the graphite material of positioning element 12, first fixing element 13, and second fixing element 14, the material of connector 11 is replaced with a wear-resistant material. This makes connector 11, which directly contacts the silicon wafer, less prone to wear and has a longer service life. This improves the overall lifespan of the graphite boat locking point and reduces the number of replacements throughout the graphite boat's lifespan, thereby reducing production costs and solving the technical problem of high production costs caused by frequent replacements due to wear in existing graphite boat locking points. Furthermore, replacing only the material of connector 11 reduces the risk of coating abnormalities caused by changes in the electric field due to the new material, thus minimizing the impact on the performance of the graphite boat and even the silicon wafer coating process.

[0025] Specifically, the material of connector 11 is wear-resistant material, such as silicon carbide, silicon nitride, alumina and other ceramic materials, or tungsten steel, titanium alloy and other metal materials. It has excellent high temperature resistance and wear resistance, and can be used for a long time in high temperature environment without deformation or damage.

[0026] Furthermore, the connector 11 includes a main body and positioning posts 112 respectively disposed at both ends of the main body. The first fixing member 13 and the second fixing member 14 are both provided with positioning through holes 17. The first fixing member 13 and the second fixing member 14 are detachably connected to the connector 11 by means of the positioning posts 112 being inserted into the positioning through holes 17.

[0027] The matching method of positioning post 112 and positioning through hole 17, while realizing the detachable connection function, facilitates the installation and positioning accuracy between the first fixing part 13 and the connecting part 11 and between the second fixing part 14 and the connecting part 11, thereby improving the assembly and maintenance of the connecting part 11, the first fixing part 13 and the second fixing part 14, and thus improving the production efficiency of graphite boat clamping points and reducing production and processing costs.

[0028] Specifically, both the first fixing member 13 and the second fixing member 14 are disc-shaped. The smooth disc shape can reduce the risk of damage to the first fixing member 13 and the second fixing member 14 during use, thereby reducing the replacement frequency and usage cost of the graphite boat jamming point.

[0029] Furthermore, both the first fixing member 13 and the second fixing member 14 are provided with positioning grooves 18, and both ends of the connector 11 are respectively engaged with the positioning grooves 18. The positioning grooves 18 facilitate positioning and installation, further reduce the assembly difficulty of the graphite boat locking points, and improve the connection strength between the connector 11 and the first fixing member 13, as well as between the connector 11 and the second fixing member 14.

[0030] Furthermore, the first fixing member 13 and the second fixing member 14 are symmetrically arranged, making the entire combined graphite boat locking point 1 structure symmetrical, thus improving stability and balance.

[0031] In one alternative embodiment, the area where the connector 11 contacts the silicon wafer is curved. The curved surface design reduces the impact force when the connector 11 contacts the silicon wafer, making the contact between the connector 11 and the silicon wafer more stable and reducing damage to the silicon wafer.

[0032] In one alternative embodiment, the first fastener 13 or the second fastener 14 includes a fastener body 191 and an engaging portion 192 connected to each other, with the engaging portion 192 located on the outer ring of the fastener body 191.

[0033] Specifically, the locking part 192 has an arc surface that guides the first positioning groove 15 or the second positioning groove 16, which can guide the silicon wafer to slide into the first positioning groove 15 or the second positioning groove 16, reduce the impact force during the silicon wafer contact process and the wear of the graphite boat locking point caused by the impact force, thereby reducing the replacement frequency of the first locking part and the second locking part and extending the service life of the graphite boat locking point.

[0034] In one alternative embodiment, the first fixing member 13, the second fixing member 14, and the positioning member 12 are all chamfered. The chamfered design can reduce sharp edges, reduce stress concentration, and improve the service life of the components.

[0035] In use, firstly, the positioning element 12 is fitted onto the main body of the connector 11. Then, the first fixing element 13 and the second fixing element 14 are respectively placed over both ends of the connector 11, so that the positioning pin 112 is inserted into the positioning through hole 17, and the end of the main body of the connector 11 is engaged in the positioning groove 18. In this way, the connector 11, the positioning element 12, the first fixing element 13, and the second fixing element 14 are combined to form a complete graphite boat locking point. The assembled graphite boat locking point is installed on the graphite boat, so that the engaging part 192 engages with the locking groove of the graphite boat to fix the locking point. Then, the silicon wafer is placed into the first positioning groove 15 and the second positioning groove 16 to fix the position of the silicon wafer.

[0036] Since the positioning component 12, the first fixing component 13, and the second fixing component 14 are all made of graphite, they have good thermal conductivity and high-temperature resistance, allowing them to be used for extended periods in high-temperature environments without deformation or damage. The connector 11 is made of wear-resistant material, exhibiting excellent wear resistance and reducing damage to the silicon wafer during contact. Furthermore, the area where the connector 11 contacts the silicon wafer is curved, further minimizing damage.

[0037] All components of the modular graphite boat jamming point 1 are detachable, facilitating replacement and maintenance. When a component fails, only that component needs to be replaced, rather than the entire jamming point, reducing maintenance costs. Simultaneously, the modular structure facilitates cleaning and maintenance, extending its service life.

[0038] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
