Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell processing, and in particular to a heating fixture and heating equipment. Background Art

[0002] In the existing application scenario of bonding two workpieces (such as the end plate and side plate of a split boat support) with a thermosetting adhesive, the thermosetting adhesive is usually poured between the two workpieces, and then placed in a thermal furnace for heating to allow the thermosetting adhesive to solidify and bond the two workpieces. However, in the case of bonding large-sized workpieces, the existing thermal furnace has a small capacity and is difficult to meet the demand. Moreover, the existing thermal furnace has a limited heating rate, and it takes a certain amount of time to cool down, which makes the bonding process of the two workpieces time-consuming and inefficient. Utility Model Content

The heating portion is used to at least partially cover a thermosetting adhesive located between two workpieces, and is used to generate heat by electromagnetic induction heating to cure the thermosetting adhesive, thereby bonding the two workpieces.

[0004] The heating jig of the embodiment of the present application can generate an induced current and heat in the heating part in the alternating magnetic field, thereby heating the heating jig. After the heating jig is heated, the heat can be transferred to the thermosetting adhesive between the two workpieces to cure the thermosetting adhesive, thereby bonding the two workpieces. Compared with the method of thermally curing thermosetting adhesives in a thermal furnace, the heating jig of the embodiment of the present application has no limit on the size of the workpieces to be bonded. Moreover, the heating jig of the embodiment of the present application adopts electromagnetic induction heating, with a fast heating rate, and during the cooling process, the two workpieces after bonding can be directly cooled by watering, which is beneficial to reduce the time consumption of the curing process and improve production efficiency. However, in the method of thermally curing thermosetting adhesives in a thermal furnace, since the operator cannot cool the two workpieces after bonding by watering, the workpieces in the thermal furnace can only be cooled naturally, which is time-consuming.

Thermosetting adhesive is filled in the first through hole, in the second through hole and between the recess and the protrusion. The heating portion is configured to be provided at least at the connection between the inner wall of the corresponding recess and the protrusion.

[0012] In some embodiments, each end plate includes two protrusions arranged at intervals, a recess is formed between the two protrusions, and the first through hole passes through the two protrusions.

DETAILED DESCRIPTION

[0024] The solar cell manufacturing process uses coating equipment, such as low-pressure chemical vapor deposition (LPCVD) coating equipment, diffusion furnaces, oxidation furnaces, plasma enhanced chemical vapor deposition (PECVD) coating equipment, etc.

[0025] At present, these coating equipments are all tube-type equipments, and the boat support is a universal carrier in most coating equipments that is responsible for automatically transporting silicon wafers into the coating process. Conventional boat supports are integrated, and their cost is higher than that of split boat supports. Moreover, when the integrated boat support is damaged, it needs to be replaced as a whole, which increases the cost of object consumption.

[0026] At present, the split boat support is bonded with thermosetting adhesives (such as inorganic high-temperature glue) and cured by low-temperature and high-temperature sintering. However, as the size of the coating equipment changes, the size of the boat support also increases accordingly, which places requirements on the size of the thermal furnace. In addition, the heating rate of the existing thermal furnace is limited (usually 10°C / min), and cooling also takes a certain amount of time. Therefore, the existing thermal furnace curing process is time-consuming and low-yield.

[0027] In this regard, the embodiment of the present application provides a heating fixture that can be used in the preparation process of the split boat support to solve the problem of small capacity and low efficiency of existing thermal furnaces. It can be understood that the heating fixture of the embodiment of the present application can also be applied to other application scenarios where two workpieces need to be bonded by a thermosetting adhesive.

[0028] Figure 1 The schematic diagram of each step of bonding two workpieces by a thermosetting adhesive is shown in FIG. Specifically, each step of bonding two workpieces includes providing two workpieces to be bonded, forming a thermosetting adhesive between the two workpieces, and a curing process to cure the thermosetting adhesive and bond the two workpieces.

[0029] like Figure 1 As shown in FIG. 1 (a), the workpieces P1 and P2 to be bonded are both in the shape of long strips. In other embodiments, the shapes of the workpieces P1 and P2 are not limited to Figure 1 shown.

[0030] like Figure 1 As shown in FIG. 2( b ), a thermosetting adhesive 20 is provided between the workpieces P1 and P2 by, for example, glue potting.

[0031] like Figure 1 As shown in Figure (c), the conventional curing process is to put workpieces P1 and P2 into a thermal furnace for curing. However, the heating rate of the thermal furnace in this method is limited (usually 10°C / min), and the bonding capacity for large workpieces is small and inefficient. In the embodiment of the present application, the curing of the thermosetting adhesive is achieved by electromagnetic induction heating through a heating fixture, thereby bonding the two workpieces.

[0032] Specifically, the heating fixture of the embodiment of the present application includes a heating portion, which is made of an electromagnetic induction material. The heating portion is used to at least partially cover the thermosetting adhesive between the two workpieces and to generate heat by electromagnetic induction heating to cure the thermosetting adhesive, thereby bonding the two workpieces.

[0033] It should be noted that in the embodiments of the present application, "electromagnetic induction material" refers to a material that can be heated by electromagnetic induction. Electromagnetic induction materials include but are not limited to the following existing materials: carbon materials (graphite, etc.), metal materials (such as copper, tungsten alloy, etc.), ceramic materials (such as silicon carbide), indium tin oxide (Indium Tin Oxide, ITO), aluminum zinc oxide (Aluminum-doped Zinc Oxide, AZO), etc.

[0034] Specifically, the heating jig can be placed in an alternating magnetic field so that the electromagnetic induction material generates an induced current and heat therein, thereby heating the heating jig. The heating jig can transfer the heat to the thermosetting adhesive to complete the thermosetting adhesive curing and sintering process.

[0035] In addition, the corresponding electromagnetic induction material can be selected according to the desired heating rate, service temperature, material loss, etc.

[0036] In some embodiments, the heating fixture can be Figure 1 The heating jig 10a shown in Figure (d) is made of a material that can be heated by electromagnetic induction. That is, the heating jig 10a is used as a heating part 11. Moreover, the heating jig 10a completely covers the thermosetting adhesive 20. The heating jig 10a is cylindrical, and the heating jig 10a covers all sides of the workpiece P1, all sides of the workpiece P2, and all sides of the thermosetting adhesive 20 between the workpiece P1 and the workpiece P2.

[0037] The heating fixture 10 a further includes a temperature detection hole H, which is used to expose the thermosetting adhesive 20 , or a position close to the thermosetting adhesive 20 , so as to detect the temperature by an infrared temperature measuring device.

[0038] In some embodiments, the heating fixture can be Figure 1 The heating jig 10b shown in Figure (d) is substantially the same as the heating jig 10a in structure. That is, the above description of the heating jig 10a can basically be applied to the heating jig 10b. The heating jig 10b is also made of a material that can be heated by electromagnetic induction. That is, the heating jig 10b is used as a heating part 11 as a whole, and the heating jig 10b is also provided with a temperature detection hole H. Unlike the heating jig 10a, the heating jig 10b is partially covered with a thermosetting adhesive 20.

[0039] Specifically, the heating jig 10b wraps part of the side surface of the workpiece P1, part of the side surface of the workpiece P2, and part of the side surface of the thermosetting adhesive 20 between the workpiece P1 and the workpiece P2. More specifically, the heating jig 10b is generally in a "concave" shape and wraps three side surfaces of the workpiece P1, three side surfaces of the workpiece P2, and three side surfaces of the thermosetting adhesive 20 between the workpiece P1 and the workpiece P2.

[0040] In some embodiments, the heating fixture can be Figure 1 The heating jig 10c shown in Figure (d) is different from the heating jigs 10a and 10b in that only a part of the heating jig 10c is made of a material that can be heated by electromagnetic induction, that is, a part of the heating jig 10c is used as the heating portion 11. Specifically, the heating jig 10c also includes a support portion 12. The support portion 12 is connected to the heating portion 11, and the support portion 12 is used to cover at least a portion of the workpiece P1 adjacent to the thermosetting adhesive 20 and to cover at least a portion of the workpiece P2 adjacent to the thermosetting adhesive 20. The support portion 12 is made of a non-electromagnetic induction material.

[0041] It should be noted that in the embodiments of the present application, "non-electromagnetic induction material" refers to a material that cannot be heated by electromagnetic induction. Non-electromagnetic induction materials include but are not limited to existing insulating materials. Specifically, the non-electromagnetic induction material can be an insulating composite ceramic, more specifically, the insulating composite ceramic can be a nitride, an oxide, or a carbide, and the melting point of the insulating composite ceramic is much lower than the operating temperature of the heating fixture.

[0042] In some embodiments, the support portion 12 is not only used to cover the portion of the workpiece P1 adjacent to the thermosetting adhesive 20 and the portion of the workpiece P2 adjacent to the thermosetting adhesive 20, but also used to cover the thermosetting adhesive 20. That is, the support portion 12 is not only provided in the area corresponding to the workpiece P1 adjacent to the thermosetting adhesive 20 and the area corresponding to the workpiece P2 adjacent to the thermosetting adhesive 20, but also provided at the location corresponding to the thermosetting adhesive 20. In this case, the heating portion 11 can be provided on the surface of the support portion 12 for covering the thermosetting adhesive 20, and can also be provided on the surface of the support portion 12 away from the surface of the support portion 12 for covering the thermosetting adhesive 20.

[0043] In other embodiments, the support portion 12 is only used to cover the portion of the workpiece P1 and the workpiece P2 adjacent to the thermosetting adhesive and is not used to cover the thermosetting adhesive 20. In this case, the heating portion 11 is sandwiched between the two support portions 12. The temperature probe hole H can be provided on the support portion 12, but is not limited thereto.

[0044] Figure 1In the three different heating jig structures shown in Figure (d), the sintering temperatures of the thermosetting adhesive 20 used are different. Specifically, the sintering temperatures of the thermosetting adhesive 20 used by the heating jig 10a, the heating jig 10b, and the heating jig 10c decrease in sequence.

[0045] Figure 1 In the three different heating jig structures shown in Figure (d), the temperatures used in the final product consisting of the workpieces P1 and P2 bonded by the thermosetting adhesive 20 are different. Specifically, the temperatures used in the final product obtained by the heating jig 10a, the heating jig 10b, and the heating jig 10c are successively lower.

[0046] Table 1

[0047]

[0048] Table 1 is a comparison of the total time and three-point bending strength of heating by a common thermal furnace and heating by electromagnetic induction using a heating fixture of an embodiment of the present application in the curing process.

[0049] It can be seen from Table 1 that compared with the traditional thermal furnace heating for curing process, using the heating fixture of the embodiment of the present application for curing process is beneficial to reducing the total time consumption of the curing process, thereby helping to improve production efficiency.

[0050] It should be noted that, due to the traditional thermal furnace heating method, the operator cannot directly cool the two workpieces after bonding in the thermal furnace by pouring water, so it takes a long time. However, when using the heating fixture of the embodiment of the present application for the curing process, the operator can directly cool the two workpieces after bonding by pouring water, which is beneficial to reduce the total time of the curing process.

[0051] It can also be seen from Table 1 above that the three-point bending strength of the specimens using the heating fixture of the embodiment of the present application for the curing process and the traditional thermal furnace heating for the curing process are roughly the same.

[0052] The heating fixture of the embodiment of the present application can locally heat the two workpieces to be bonded without being limited by the size of the workpieces.

[0053] The following heating fixture is used for Figure 2 and Figure 3 Taking the preparation process of the split boat support shown in as an example, the structure of the heating jig of different embodiments of the present application is specifically described.

[0054] like Figure 2 As shown, the split boat support 30 includes two end plates 31 , two side plates 32 and a plurality of connecting members 33 .

[0055] The two end plates 31 are arranged opposite to each other along the first direction D1. The two side plates 32 are arranged opposite to each other along the second direction D2. Each end plate 31 is connected to a side plate 32 on two opposite sides along the second direction D2. Each side plate 32 is connected to an end plate 31 on two opposite sides along the first direction D1. The two end plates 31 and the two side plates 31 enclose an inner cavity R of the split boat support 30. The depth direction of the inner cavity R, or the height direction of the split boat support 30 is defined as a third direction D3. The first direction D1, the second direction D2 and the third direction D3 intersect each other. In this embodiment, the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0056] Each end plate 31 includes two protrusions 311 spaced apart along the third direction D3 on opposite sides along the second direction D2. A recess 312 is formed between the two protrusions 311. Each end plate 31 is also provided with a first through hole 31h. The first through hole 31h passes through the two protrusions 311 and is connected to the recess 312. Each side plate 32 includes a protrusion 321 on opposite sides along the first direction D1, and the size and shape of the protrusion 321 and the recess 312 are adapted. Each protrusion 321 is also provided with a second through hole 32h corresponding to the first through hole 31h.

[0057] Please refer to Figure 2 and Figure 3 Each connecting member 33 is provided with a first through hole 31h and a corresponding second through hole 32h to connect an end plate 31 and a corresponding side plate 32. In this embodiment, the connecting member 33 is a pin, but is not limited thereto.

[0058] In order to enhance the connection strength between the end plate 31 and the corresponding side plate 32, a thermosetting adhesive 20 is filled in the first through hole 31h, the second through hole 32h, and between the recess 312 and the protrusion 321 to bond the end plate 31 and the side plate 32. That is, the two workpieces to be bonded described above can be an end plate 31 in the split boat support 30 and a side plate 32 correspondingly connected to the end plate 31. In the split boat support 30, the materials of the end plate 31 and the side plate 32 can be ceramic materials such as silicon carbide, aluminum nitride, silicon nitride, etc., but are not limited thereto.

[0059] like Figure 4 As shown, the heating fixture 10 d of the first embodiment includes a top plate 130 , a first connecting plate 131 and a second connecting plate 132 .

[0060] Please refer to Figure 3 and Figure 4 The top plate 310 is used to be hung on the end plate 31 and the side plate 32 connected to the end plate 31 .

[0061] The first connecting plate 131 is connected to the top plate 310 and is disposed corresponding to the end plate 31. The first connecting plate 131 is configured to cover the side of the two protrusions 311 away from the inner cavity R and the side of the protrusion 321 away from the inner cavity R along the first direction D1. The second connecting plate 132 is connected to the top plate 310 and is disposed corresponding to the side plate 32. The second connecting plate 132 is configured to cover the side of the two protrusions 311 away from the inner cavity R and the side of the protrusion 321 away from the inner cavity R along the second direction D2.

[0062] It should be noted that the first connecting plate 131 is arranged corresponding to the end plate 31, which means that the first connecting plate 131 and the end plate 31 are substantially coplanar, or the first connecting plate 131 is substantially perpendicular to the side plate 32. The second connecting plate 132 is arranged corresponding to the side plate 32, which means that the second connecting plate 132 and the side plate 32 are substantially coplanar, or the second connecting plate 132 is substantially perpendicular to the end plate 31.

[0063] In this embodiment, the outer contour of the top plate 310 is roughly a right triangle. The first connecting plate 131 and the second connecting plate 132 are respectively connected to the two right angles of the right triangle in the contour of the top plate 310, and the first connecting plate 131 and the second connecting plate 132 are connected and cover the surface of the corner formed by the connection of the end plate 31 and the side plate 32 away from the inner cavity R.

[0064] In this embodiment, the entire heating fixture 10d is made of electromagnetic induction material. That is, the entire heating fixture 10d is used as the heating part 11. In other words, in the heating fixture 10d, the top plate 310, the first connecting plate 131 and the second connecting plate 132 respectively constitute components of the heating part 11.

[0065] The temperature detection hole H may be formed on the first connecting plate 131 and / or the second connecting plate 132. Specifically, the temperature detection hole H may be disposed at the connection between the protrusion 311 and the protrusion 321, for example, the temperature detection hole H may expose the thermosetting adhesive 20, or the temperature detection hole H may be disposed adjacent to the location where the thermosetting adhesive 20 is located. The number of the temperature detection hole H may be, but is not limited to, one.

[0066] In the heating fixture 10d, the top plate 130, the first connecting plate 131 and the second connecting plate 132 are integrally formed. In other embodiments, the top plate 130, the first connecting plate 131 and the second connecting plate 132 may be connected by fasteners.

[0067] like Figure 5As shown, the structure of the heating jig 10e of the second embodiment is roughly the same as that of the heating jig 10d of the first embodiment, and the main difference between the two is that the heating jig 10e also includes a third connecting plate 133. Specifically, the third connecting plate 133 is connected to the top plate 130, and is configured to cover the surface of the inner cavity R formed at the corner formed by the connection of the end plate 31 and the side plate 32. Further, the third connecting plate 133 is configured to at least cover one side of the two protrusions 311 forming the inner cavity R and one side of the protrusion forming the inner cavity R. The heating jig 10e is made of electromagnetic induction material as a whole. That is, the heating jig 10e is used as the heating part 11 as a whole. In other words, in the heating jig 10e, the top plate 310, the first connecting plate 131, the second connecting plate 132 and the third connecting plate 133 respectively constitute components of the heating part 11.

[0068] In the heating fixture 10e, the top plate 130, the first connecting plate 131, the second connecting plate 132 and the third connecting plate 133 are integrally formed. In other embodiments, the top plate 130, the first connecting plate 131, the second connecting plate 132 and the third connecting plate 133 can be connected by fasteners.

[0069] like Figure 6 As shown, the main difference between the heating jig 10f of the third embodiment and the heating jig 10d of the first embodiment is that the heating jig 10f includes a heating portion 11 made of an electromagnetic induction material and also includes a supporting portion 12 made of a non-electromagnetic induction material. Specifically, in the heating jig 10f, the top plate 130 is made of a non-electromagnetic induction material, and the first connecting plate 131 and the second connecting plate 132 each include a plurality of heating portions 11 and a plurality of supporting portions 12.

[0070] Please refer to Figure 2 , Figure 3 and Figure 6 In the heating fixture 10 f , the heating portion 11 included in the first connecting plate 131 and the heating portion 11 included in the second connecting plate 132 are both arranged to correspond to the connection between the inner wall of the recess 312 and the protrusion 321 .

[0071] In some embodiments, the support portion 12 is made of insulating composite ceramics, but is not limited thereto. The insulating composite ceramics may be nitrides, oxides, or carbides, and the melting point of the insulating composite ceramics is much lower than the operating temperature of the heating fixture 10f.

[0072] The heating jig 10d of the first embodiment has a smaller wrapping area than the heating jig 10f of the second embodiment, but is more convenient to install.

[0073] The heating jig 10f of the second embodiment has a larger wrapping surface than the heating jig 10d of the first embodiment. Therefore, when the thermosetting adhesive is heated during the curing process, the temperature is more uniform and the consistency is better.

[0074] The heating jig 10f of the third embodiment is only provided with a heating portion 11 corresponding to the connection between the inner wall of the recess 312 and the protrusion 321, while a supporting portion 12 made of insulating composite ceramic is provided at other positions, which is beneficial to reducing the heat storage problem of the assembly composed of the heating jig 10f and the split boat support 30, reducing the thermal shock of the assembly composed of the heating jig 10f and the split boat support 30, and reducing the thermal stress of the assembly composed of the heating jig 10f and the split boat support 30.

[0075] In some embodiments, the thermosetting adhesive 20 is an inorganic high temperature adhesive that can withstand a temperature of 1100° C. for a long time and can withstand acid and alkali washing, but is not limited thereto.

[0076] In summary, the heating jig of the embodiment of the present application can be used to bond large-sized workpieces, and is beneficial to reducing the time consumption of the thermosetting adhesive curing process and improving production efficiency.

[0077] The embodiment of the present application also provides a heating device. The heating device includes an electromagnetic heating component and a heating fixture in any of the above embodiments. The electromagnetic heating component is used to generate an alternating magnetic field when powered on, so that the heating fixture in the alternating magnetic field generates heat. Specifically, the electromagnetic heating component includes, for example, an electromagnetic coil and a circuit electrically connected to the electromagnetic coil, etc.

[0078] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
