Description

Technical Field

[0001] This disclosure relates to the fields of photovoltaic and semiconductor technology, and specifically to a boat structure. Background Technology

[0002] The manufacturing of photovoltaic or semiconductor products involves processes such as texturing, diffusion, laser scanning, etching, coating, printing, sintering, and testing. Some of these processes require transporting the products to a reactor for processing at high temperatures. Currently, the industry typically uses a boat structure to support the products, with a thermal field set up on the reactor to heat both the boat structure and the products.

[0003] Typically, after the boat structure carrying the product is transported into the reactor, the thermal field is energized and generates heat. This heat is transferred to the boat structure and the product, heating them to the required process temperature. However, because the thermal field of the reactor is relatively far from the boat structure, a significant amount of heat is lost during the transfer process, resulting in low heat utilization and low heating efficiency of the thermal field on the boat structure and product. Furthermore, due to the large size of the boat structure, the area closer to the thermal field has a higher heat distribution than the area farther away, leading to poor heat uniformity around the boat structure and consequently, uneven heating of the boat structure and product by the thermal field. Utility Model Content

[0004] In view of this, the present disclosure provides a boat structure that solves the problem that the utilization rate of heat around the boat structure is low and the distribution uniformity is poor, resulting in low heating efficiency and poor uniformity of the product.

[0009] In some embodiments, the sheet placement area includes a quadrilateral area, and a plurality of the sub-supports are respectively disposed on three sides of the sheet placement area, so that the other side of the sheet placement area forms a sheet inlet / outlet, and the sheet enters and exits the sheet placement area through the sheet inlet / outlet.

[0010] In some embodiments, the first connection component includes: a first connector, which is insulated from the support member; and a conductive member, which is insulated from the first connector and electrically connects the end of the heating wire to the positive or negative terminal of the first power supply.

[0012] In some embodiments, the boat piece has a plurality of third connecting holes, and the support member has a plurality of fourth connecting holes, with the plurality of third connecting holes and the plurality of fourth connecting holes being arranged in a one-to-one correspondence; wherein, the boat structure further includes: a plurality of third connecting members, arranged in a one-to-one correspondence with the plurality of third connecting holes and the plurality of fourth connecting holes, the third connecting members passing through the corresponding third connecting holes and fourth connecting holes, wherein the material of the third connecting members is an insulating material; a plurality of limiting sleeves, disposed between the support member and the boat piece, and fitted onto the third connecting members, wherein the two sides of the limiting sleeves respectively contact the support member and the boat piece to limit the position of the heating component and the boat piece, wherein the material of the limiting sleeves is an insulating material; a plurality of second locking members, respectively arranged corresponding to the plurality of third connecting members, wherein every two second locking members are threadedly connected to the two ends of the corresponding third connecting member, the second locking members being configured to lock the boat piece and the third connecting member, or the heating component and the third connecting member.

Detailed Implementation

[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0029] Figure 1 The diagram shown is a schematic representation of an application scenario of the boat structure provided in an embodiment of this disclosure. Figure 1As shown, the boat structure 10 is configured to carry and heat the sheet 2. The boat structure 10 includes at least one boat piece 100, at least one heating assembly 200, and at least two first connecting assemblies 300. The boat piece 100 has at least one sheet placement area 1001 configured to accommodate the sheet 2. The heating assembly 200 is disposed around the periphery of the sheet placement area 1001 and is insulated from the boat piece 100, and is configured to heat the sheet 2. One first connecting assembly 300 is electrically connected to one end of the heating assembly 200 to the positive terminal of the first power supply 3, and the other first connecting assembly 300 is electrically connected to the other end of the heating assembly 200 to the negative terminal of the first power supply 3, so that the heating assembly 200 can be energized and generate heat.

[0030] The boat structure 10 provided in this embodiment uses a heating component 200 to heat the boat sheet 100 and the sheet 2 supported by the boat sheet 100. Since the heating component 200 is very close to the boat sheet 100, the heat generated by the heating component 200 can be fully utilized, reducing heat loss, improving heat utilization, and increasing the heating efficiency of the heating component 200 on the boat sheet 100 and the sheet 2. Furthermore, since the heating component 200 is arranged around the periphery of the sheet placement area 1001, the uniformity of heat distribution around the sheet placement area 1001 is improved, thereby improving the heating uniformity of the sheet 2 by the heating component 200.

[0031] Furthermore, in related technologies, the thermal field of the reactor is typically located on the outside of the cavity, and the heat provided by the thermal field is transferred to the boat structure and product inside the reactor through the cavity. To improve the heat transfer performance of the cavity, quartz is typically used as the cavity material; however, quartz cavities are expensive, leading to high reactor manufacturing costs. The boat structure 10 provided in this embodiment has a built-in heating assembly 200, thus eliminating the need for a thermal field in the reactor and saving on manufacturing costs. Additionally, when the reactor does not have a thermal field, the cavity material can be other than quartz to further reduce manufacturing costs.

[0032] In addition, quartz material cavities are prone to breakage at high temperatures and have a short service life. Using materials other than quartz that are not easily broken under high temperatures to make cavities can not only improve the service life of the cavities, but also avoid the problem of residues remaining on the hot zone due to cavity breakage that are difficult to clean, or even cause damage to the hot zone and render it unusable.

[0033] For example, such as Figure 1 As shown, the boat structure 10 includes a boat sheet 100, a heating assembly 200 and two first connecting assemblies 300, and the boat sheet 100 has a sheet placement area 1001.

[0034] For example, the heating component 200 may be a heating rod, a heating plate, etc.

[0035] Figure 2 The diagram shown is a structural schematic of the boat structure and sheet provided in an embodiment of this disclosure. Figure 3 As shown Figure 2 The diagram shows a magnified view of the boat structure and sheet material in area A. Figure 4 The diagram shown is a structural schematic of a heating assembly provided in an embodiment of this disclosure. Figure 5 As shown Figure 4 The image shows a magnified view of the heating component in region B. Figure 6 The diagram shown is a structural schematic of a heating assembly, a first connecting assembly, and a first power supply provided in an embodiment of this disclosure. Figures 2 to 6 As shown, the heating assembly 200 includes a support member 210 and a heating wire 220. The support member 210 is disposed around the periphery of the sheet placement area 1001 and is connected to the boat sheet 100 and the first connecting assembly 300 respectively. The material of the support member 210 is an insulating material. The heating wire 220 is wound around the support member 210. One first connecting assembly 300 is electrically connected to one end of the heating wire 220 and the positive terminal of the first power supply 3, and the other first connecting assembly 300 is electrically connected to the other end of the heating wire 220 and the negative terminal of the first power supply 3.

[0036] The heating component 200 has a simple structure and provides good heating uniformity for the sheet 2.

[0037] For example, the material of the support member 210 may be ceramic, plastic, etc.

[0038] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the sheet placement area 1001 includes a polygonal region, and the support member 210 includes multiple sub-support members 2110. The multiple sub-support members 2110 are respectively disposed on multiple sides of the sheet placement area 1001, and adjacent sub-support members 2110 are interconnected. The sub-support member 2110 has a long strip-shaped structure, and in the width direction of the sub-support member 2110, each of its two opposite sides has multiple first limiting grooves 2111. The multiple first limiting grooves 2111 located on the same side are arranged at intervals along the length direction of the sub-support member 2110. The first limiting grooves 2111 penetrate the sub-support member 2110 along its thickness direction. The first limiting grooves 2111 are configured to limit the heating wire 220.

[0039] The first limiting groove 2111 facilitates the winding of the heating wire 220 around the sub-support member 2110 or the removal of the heating wire 220 from the sub-support member 2110. In addition, by using the first limiting groove 2111 to limit the heating wire 220, it is possible to prevent the heating wire 220 from shifting on the sub-support member 2110 or falling off the sub-support member 2110.

[0040] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the thickness direction of the sub-support 2110 is perpendicular to the boat 100. The opening of the first limiting groove 2111 near the sheet placement area 1001 faces the sheet placement area 1001, and the opening of the first limiting groove 2111 away from the sheet placement area 1001 faces away from the sheet placement area 1001. The heating wire 220 can enter and exit the first limiting groove 2111 through the opening.

[0041] In some embodiments, such as Figure 2 As shown, the sheet placement area 1001 includes a quadrilateral area, and multiple sub-support members 2110 are respectively disposed on three sides of the sheet placement area 1001, so that the other side of the sheet placement area 1001 forms a sheet inlet / outlet 1002, through which the sheet 2 enters and exits the sheet placement area 1001.

[0042] By setting up the sheet material inlet and outlet 1002, the sub-support member 2110 avoids interference with the sheet material 2 when it enters or leaves the sheet material placement area 1001, thus making it easier to place the sheet material 2 in the sheet material placement area 1001.

[0043] For example, such as Figure 2 As shown, the boat structure 10 includes multiple locking points 700, all of which are connected to the boat sheet 100. The area enclosed by the multiple locking points 700 is the sheet placement area 1001. The locking points 700 cooperate with the boat sheet 100 to clamp the edge of the sheet 2, so that the sheet 2 is placed in the sheet placement area 1001 and does not fall off.

[0044] In some embodiments, such as Figure 6 and Figure 7 As shown, the first connection assembly 300 includes a first connector 310 and a conductive element 320. The first connector 310 is insulated from the support member 210, and the conductive element 320 is insulated from the first connector 310 and electrically connects the end of the heating wire 220 to the positive or negative terminal of the first power supply 3.

[0045] The first connecting component 300 described above has a simple structure and a simple and reliable connection method.

[0046] For example, the material of the first connector 310 is an insulating material. For example, the material of the first connector 310 may be ceramic, plastic, etc.

[0047] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the first connector 310 includes at least two limiting portions 3101 and connecting portions 3102 arranged sequentially at intervals along a first direction X1, which is perpendicular to the boat piece 100. The connecting portions 3102 connect at least two limiting portions 3101, such that each pair of adjacent limiting portions 3101 and connecting portions 3102 form a second limiting groove 3112. The second limiting groove 3112 engages with the end of the support member 210, and the conductive member 320 is insulated from the connecting portion 3102. The limiting portion 3101 has a first connecting hole 3111 penetrating the limiting portion 3101 along the first direction X1, and the end of the support member 210 has a second connecting hole 2101 penetrating the support member 210 along the first direction X1. The first connecting assembly 300 also includes a second connector 330 and two first locking members 340. The second connector 330 passes through the first connecting hole 3111 and the second connecting hole 2101. The two first locking members 340 are threadedly connected to both ends of the second connector 330 respectively. The first locking members 340 are configured to lock the support member 210 and the first connector 310.

[0048] The above configuration enables the support member 210 and the first connecting member 310 to be detachably connected, so as to facilitate the replacement and maintenance of the heating component 200 and the first connecting component 300.

[0049] In some embodiments, such as Figures 8 to 10 As shown, the boat piece 100 has multiple third connecting holes 1003, and the support member 210 has multiple fourth connecting holes 2102, with each of the multiple third connecting holes 1003 and the multiple fourth connecting holes 2102 corresponding to one another. The boat structure 10 also includes multiple third connecting members 400, multiple limiting sleeves 500, and multiple second locking members 600. Each of the multiple third connecting members 400 corresponds to each of the multiple third connecting holes 1003 and the multiple fourth connecting holes 2102, and the third connecting members 400 pass through the corresponding third connecting holes 1003 and fourth connecting holes 2102. The material of the third connecting members 400 is an insulating material.

[0050] A limiting sleeve 500 is disposed between the support member 210 and the boat piece 100, and is fitted onto the third connecting member 400. The two sides of the limiting sleeve 500 contact the support member 210 and the boat piece 100 respectively, to limit the position of the heating assembly 200 and the boat piece 100. The limiting sleeve 500 is made of insulating material. Multiple second locking members 600 are respectively disposed corresponding to multiple third connecting members 400. Every two second locking members 600 are threadedly connected to both ends of the corresponding third connecting member 400. The second locking members 600 are configured to lock the boat piece 100 and the third connecting member 400, or the heating assembly 200 and the third connecting member 400.

[0051] The connection between the heating assembly 200 and the boat 100 is simple and reliable. Furthermore, this design allows for a detachable connection between the heating assembly 200 and the boat 100, facilitating replacement and maintenance of both components.

[0052] For example, such as Figure 4 , Figure 8 and Figure 9 As shown, each sub-support member 2110 has a fourth connecting hole 2102 at its end. The multiple third connecting holes 1003 and multiple fourth connecting holes 2102 of the boat piece 100 are arranged in a one-to-one correspondence. Multiple third connectors 400 pass through their respective third connecting holes 1003 and fourth connecting holes 2102 to achieve a stable connection between the heating assembly 200 and the boat piece 100.

[0053] For example, the material of the third connector 400 may be ceramic, plastic, etc. For example, the material of the limiting sleeve 500 may be ceramic, plastic, etc.

[0054] In some embodiments, such as Figure 2 As shown, the boat sheet 100 extends along the second direction X2. The boat sheet 100 has a plurality of sheet placement areas 1001 arranged at intervals along the second direction X2. A heating component 200 is provided around each sheet placement area 1001. The plurality of heating components 200 are connected in sequence. The second direction X2 is parallel to the boat sheet 100.

[0055] By providing multiple sheet placement areas 1001 on the boat 100 to accommodate the sheet 2, the load-bearing capacity of the boat 100 is further increased. Furthermore, by providing heating components 200 around each sheet placement area 1001, the uniformity of heat distribution around each sheet placement area 1001 is improved, thereby enhancing the heating efficiency and uniformity of the heating components 200 on each sheet 2.

[0056] For example, such as Figure 2As shown, the boat 100 has two sheet placement areas 1001 arranged at intervals along a second direction X2. There are two heating components 200, which are respectively disposed around the periphery of the two sheet placement areas 1001 and connected to each other. The two heating components 200 form an integral structure, so that both heating components 200 can be simultaneously loaded and unloaded from the boat 100.

[0057] In some embodiments, such as Figure 6 and Figure 10 As shown, there are multiple boat pieces 100, heating components 200, and first connecting components 300. Multiple boat pieces 100 and multiple heating components 200 are arranged in multiple rows at intervals along a first direction X1, and the multiple rows of boat pieces 100 and multiple rows of heating components 200 are arranged alternately. Multiple first connecting components 300 are arranged in multiple rows along the first direction X1 and in two columns along a second direction X2. For two first connecting components 300 in the same row, one first connecting component 300 is electrically connected to one end of the corresponding row's heating component 200 and to the positive terminal of the first power supply 3, and the other first connecting component 300 is electrically connected to the other end of the corresponding row's heating component 200 and to the negative terminal of the first power supply 3. Multiple first connecting components 300 in the same column are insulated from each other, with the first direction X1 perpendicular to the second direction X2.

[0058] The boat structure 10 utilizes multiple boat pieces 100 to support multiple sheets 2, further increasing the load-bearing capacity of the boat structure 10.

[0059] In addition, the multiple rows of boat sheets 100 and the multiple rows of heating components 200 are arranged alternately to improve the uniformity of heat distribution around each boat sheet 100, thereby improving the heating uniformity of the heating components 200 on the sheet 2 carried by each boat sheet 100.

[0060] In addition, by individually energizing each heating component 200, each heating component 200 can individually heat the adjacent boat piece 100 and the sheet 2 carried by the boat piece 100, thereby realizing the zoned heating of the boat structure 10.

[0061] For example, such as Figures 8 to 10 As shown, the third connector 400 passes through the multiple rows of boat pieces 100 and the multiple rows of heating components 200 in sequence, and a limiting sleeve 500 is provided between each adjacent boat piece 100 and heating component 200. Two second locking pieces 600, which are provided corresponding to the third connector 400, are threadedly connected to both ends of the third connector 400.

[0062] For example, such as Figure 8As shown, the boat sheets 100 located in the (2N-1)th row are electrically connected to each other and to the positive terminal of the second power supply. The boat sheets 100 located in the 2Nth row are electrically connected to each other and to the negative terminal of the second power supply, so that adjacent rows of boat sheets 100 are respectively electrically connected to the positive and negative terminals of the second power supply, where N is an integer equal to or greater than 1. This arrangement creates a potential difference between adjacent rows of boat sheets 100, facilitating the ionization of the process gas between adjacent rows of boat sheets 100 for coating the sheet 2, while also improving the coating uniformity of the sheet 2 carried by each row of boat sheets 100.

[0063] Exemplarily, the boat structure 10 further includes an electrode feeder 800, which electrically connects the boat piece 100 located in the 2N-1th row to the positive terminal of the second power supply, or the boat piece 100 located in the 2Nth row to the negative terminal of the second power supply. Exemplarily, the electrode feeder 800 has an electrode connection hole 801, so that when the boat structure 10 is placed in the reactor, the electrode in the reactor is inserted into the electrode connection hole 801, thereby realizing the electrical connection of the electrode feeder 800 to the positive or negative terminal of the second power supply through the electrode.

[0064] For example, the material of the boat 100 can be a conductive material such as graphite or silicon carbide.

[0065] In the embodiments of this disclosure, unless otherwise specified, the connection can be a detachable connection using bolts, nuts, screws, clips, magnets, etc. In some connections where there is no particular requirement for a detachable fit, a non-detachable connection can be achieved through welding, bonding, etc.
