Description

Technical Field

[0001] The utility model belongs to the technical field of solar photovoltaic manufacturing, and more specifically, relates to a spliced carrier for carrying silicon wafers. Background Art

[0002] Solar photovoltaic technology is a new energy technology that converts solar energy into electrical energy. With the continuous development of the photovoltaic industry, diffusion, oxidation, annealing, CVD (Chemical Vapor Deposition), coating, etc. have become essential processes in the production of new energy batteries. In processes such as diffusion, oxidation, and annealing, carriers are usually used to carry, transport, and convey silicon wafers.

[0003] Existing carriers usually consist of two side end plates and intermediate slot bars. The two ends of the slot bars are respectively welded to the two side end plates. The slot bars are provided with card slots for placing silicon wafers at certain intervals along their length directions. Since the carrier is prone to deformation during welding, and there are deviations in the positions between the slot bars and between the slot bars and the end plates during welding, the card slots on the slot bars need to be processed as a whole after welding. Otherwise, the positions of the card slots on the slot bars are likely to deviate, resulting in the actual position of the silicon wafers being inconsistent with the design, increasing the difficulty of automatic wafer insertion and removal. Also, because the overall size of the carrier is large after welding, the equipment required for processing positions such as card slots is correspondingly large. Also, due to the need to ensure the corresponding positions of the card slots on each slot bar, the processing difficulty is high, and once there is a processing error, the whole needs to be scrapped, so the cost is high.

[0004] To reduce costs, for example, in the existing patent CN21848336U, it is proposed to set the slot bar to be detachably connected to the end plate. Specifically, hooks are provided on the inner sides of the end plates, and grooves are provided on the slot bars, and the grooves can be engaged with the corresponding hooks. By providing mutually engaged hooks and grooves, the disassembly or installation between the slot bar and the end plate can be facilitated. However, due to disadvantages such as relatively small contact area, weak load-bearing capacity, and easy fracture when the hooks are engaged with the grooves, the overall reliability of the carrier is reduced, and the service life is shortened.

[0005] Therefore, how to propose a more reliable spliced carrier is an urgent problem to be solved in the industry. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a spliced carrier, which can first process the card slots on the slot bars separately and then splice the slot bars and the end plates together, thereby reducing the processing difficulty and the manufacturing cost; and, card shafts are provided at both ends of the slot bars, and hole positions are provided on the end plates, and the card shafts are correspondingly engaged with the hole positions, so that the engagement connection between the slot bars and the end plates is more reliable, and the service life is extended.

[0007] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0008] The present utility model provides a spliced vehicle, including two end plates arranged oppositely, and a plurality of grooved rods. A plurality of card slots are arranged at intervals along the length direction of the grooved rod body of each grooved rod. Each end plate is provided with a plurality of holes. A card shaft is arranged at each end of each grooved rod, and the two ends of each grooved rod are respectively and correspondingly clamped with the holes of the two end plates through the card shafts.

[0009] Further, the two end plates are arranged vertically, the card shafts in each grooved rod are arranged horizontally, and the grooved rod body is arranged obliquely.

[0010] Further, the included angle between the axis of the card shaft and the axis of the grooved rod body in each grooved rod is 2° to 8°.

[0011] Further, a plurality of outer positioning planes are arranged on the outer side of each card shaft, and a plurality of inner positioning planes are arranged on the inner side of each hole. The outer positioning planes and the inner positioning planes are correspondingly attached to each other.

[0012] Further, the plurality of grooved rods include an upper grooved rod group and a lower grooved rod group, and the number of upper grooved rods in the upper grooved rod group is the same as or different from the number of lower grooved rods in the lower grooved rod group.

[0013] Further, the number of the upper grooved rods and the number of the lower grooved rods are both two.

[0014] Further, the opening directions of the card slots in each upper grooved rod are arranged oppositely to the opening directions of the card slots in the corresponding lower grooved rod.

[0015] Further, each end plate is provided with at least one lug for connecting with a boat support.

[0016] Further, the spliced vehicle is made of quartz material, silicon carbide or ceramic material.

[0017] Further, each end plate and each lug are made of silicon carbide material, and each grooved rod is made of quartz material.

[0018] Compared with the prior art, the spliced vehicle provided by the present utility model has at least the following beneficial effects:

[0019] 1. By providing clamping shafts at both ends of the slot bar and hole positions on the end plate, the connection between the slot bar and the end plate of the carrier is achieved by splicing. Moreover, compared with the existing technology of using a hook and a groove for clamping, the clamping shaft of the slot bar is clamped corresponding to the hole position on the end plate, and the clamping shaft and the hole position are in close contact, which has higher positioning accuracy, better connection reliability and higher bearing capacity, reducing the displacement or detachment of the slot bar due to loosening or vibration, and thus it is not easy for the slot position of the slot bar to shift. Therefore, it ensures that the slot bar with the processed slot and the end plate do not affect the automatic insertion and unloading of the sheet after splicing, better replacing the integrated carrier design of first welding as a whole and then processing the slot, thereby reducing the processing difficulty and manufacturing cost.

[0020] 2. By vertically arranging the end plate, horizontally arranging the clamping shaft and obliquely arranging the slot bar body, it is applicable to the setting of the silicon wafer perpendicular to the cross-section direction of the furnace mouth. Under the same aperture conditions, more silicon wafers can be placed, while meeting better processes and ensuring the connection reliability between the end plate and the slot bar.

[0021] 3. By providing an outer positioning plane on the clamping shaft and an inner positioning plane on the hole position, the outer positioning plane and the inner positioning plane are in close fit, preventing the slot bar from rotating relative to the end plate, and thus avoiding the shift of the slot position of the slot bar.

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0044] Currently, when manufacturing a vehicle, usually the two ends of the groove bar are respectively welded to the two side end plates, and then the card slots on the groove bar are processed. This integrated vehicle design has high processing difficulty, high manufacturing cost, and high maintenance cost. In addition, there are a few people in the industry who propose a solution to set the groove bar to be detachably connected to the end plate. By setting the hooks and grooves that are engaged with each other, it is convenient to disassemble or install the groove bar and the end plate, reducing the maintenance cost. However, due to the disadvantages such as relatively small contact area, weak bearing capacity, and easy fracture when the hook and the groove are engaged, the overall reliability of the vehicle is reduced, and the service life is shortened.

[0045] To solve the above problems, the present utility model proposes a spliced vehicle.

[0046] As Figure 1 shown, the spliced vehicle provided by the preferred embodiment of the present utility model includes: two end plates 1 arranged oppositely, and a plurality of groove bars 2. A plurality of card slots 4 are arranged at intervals along the length direction of the groove bar body 20 of each groove bar 2. Each end plate 1 is provided with a plurality of hole positions 6. Card shafts 5 are respectively arranged at both ends of each groove bar 2, and both ends of each groove bar 2 are respectively engaged with the hole positions 6 of the two end plates 1 through the card shafts 5.

[0047] By respectively providing the card shafts 5 at both ends of the groove bar 2 and the hole positions 6 on the end plate 1, the connection between the groove bar 2 of the vehicle and the end plate 1 is realized in a splicing manner; and, compared with the prior art in which the hook and the groove are engaged, through the corresponding engagement of the card shaft 5 of the groove bar 2 and the hole position 6 of the end plate 1, the card shaft 5 and the hole position 6 are in close contact, having higher positioning accuracy, better connection reliability, and higher bearing capacity, reducing the displacement or detachment of the groove bar 2 due to loosening or vibration, and it is not easy for the position of the card slot 4 of the groove bar 2 to shift, thereby ensuring that the groove bar 2 with the processed card slot 4 and the end plate 1 are spliced without affecting the automatic insertion and unloading of the chip, better replacing the integrated vehicle design of first welding as a whole and then processing the card slot 4, and thus reducing the processing difficulty and manufacturing cost.

[0048] In the preferred embodiment, as Figure 1 、 Figure 3 shown, the two end plates 1 are arranged vertically, the card shafts 5 in each groove bar 2 are arranged horizontally, and the groove bar body 20 is arranged obliquely.

[0049] In the process of manufacturing a photovoltaic cell, a carrier for holding the silicon wafer 3 is required in a processing furnace. By pushing the boat support, the carrier holding the silicon wafer 3 is driven to send the silicon wafer 3 into the processing furnace. In this preferred embodiment, the end plate 1 is vertically arranged, the clamping shaft 5 is horizontally arranged, and the groove bar body 20 is obliquely arranged, so that the silicon wafer 3 is vertically arranged in the direction perpendicular to the furnace mouth section and obliquely arranged on the carrier, while ensuring the connection reliability between the end plate 1 and the groove bar 2. Compared with the case where the silicon wafer 3 is arranged parallel to the furnace mouth section, under the same aperture condition, this preferred embodiment can place more silicon wafers 3 in the carrier, while meeting better processes, and has better practicability.

[0050] In the preferred embodiment, as Figure 5 , Figure 6 , Figure 8 and Figure 9 shown, the included angle between the axis of the clamping shaft 5 and the axis of the groove bar body 20 in each groove bar 2 is 2° to 8°.

[0051] The inclination angle of the groove bar body 20 is set to 2° to 8°. Through experimental verification, the inclination angle within this range can enable the silicon wafer 3 to have better process effects and meet the process optimization requirements when the silicon wafer 3 is placed obliquely.

[0052] In the preferred embodiment, the opening angle of the clamping groove 4 of each groove bar 2 to both sides is in a V shape.

[0053] By adopting the inclined arrangement of the groove bar body 20 and the V-shaped opening angle of the clamping groove 4 to both sides, the contact between the silicon wafer 3 and the clamping groove 4 is a line contact, with a small contact area, reducing the possibility of the silicon wafer 3 being contaminated and the pollution risk.

[0054] In the preferred embodiment, as Figure 1 , Figure 4 and Figure 7 shown, a plurality of outer positioning planes 7 are provided on the outer side of each clamping shaft 5, and a plurality of inner positioning planes (not marked in the figure) are provided on the inner side of each hole 6, and the outer positioning planes 7 and the inner positioning planes are in one-to-one correspondence and fit closely.

[0055] It should be understood that the number of outer positioning planes 7 in each clamping shaft 5 can be two or four, and correspondingly, the number of inner positioning planes in each hole 6 can be two or four.

[0056] By providing the outer positioning planes 7 on the clamping shaft 5 and the inner positioning planes on the hole 6, and the outer positioning planes 7 and the inner positioning planes fit closely, it is prevented that the groove bar 2 rotates relative to the end plate 1, and further the relative positions of the clamping grooves 4 between the plurality of groove bars 2 are prevented from shifting.

[0057] In a preferred embodiment, the plurality of groove rods 2 includes an upper groove rod group and a lower groove rod group, and the number of the upper groove rods 21 in the upper groove rod group may be the same as or different from the number of the lower groove rods 22 in the lower groove rod group.

[0058] It should be understood that the specific number of the upper groove rods 21 and the lower groove rods 22 can be reasonably set according to the size of the silicon wafer 3 in the actual application. In this preferred embodiment, the number of the upper groove rods 21 in the upper groove rod group is two or more, and the number of the lower groove rods 22 in the lower groove rod group is two or more.

[0059] For example, if the size of the silicon wafer 3 is relatively large, the upper groove rod group can be composed of four upper groove rods 21 arranged in parallel, and at the same time, the lower groove rod group can be composed of four lower groove rods 22 arranged in parallel.

[0060] For another example, if the size of the silicon wafer 3 is relatively small, the upper groove rod group can be composed of two upper groove rods 21 arranged in parallel, and at the same time, the lower groove rod group can be composed of two lower groove rods 22 arranged in parallel.

[0061] Of course, in other embodiments, two upper groove rods 21 can also be paired with one lower groove rod 22 to carry the silicon wafer 3.

[0062] In a preferred embodiment, if the number of the upper groove rods 21 in the upper groove rod group is the same as the number of the lower groove rods 22 in the lower groove rod group, that is, the upper groove rods 21 and the lower groove rods 22 are in one-to-one correspondence, the opening directions of the card slots 4 in each upper groove rod 21 can be set to be opposite to the opening directions of the card slots 4 in the corresponding lower groove rods 22, so as to form a space for accommodating the silicon wafer 3.

[0063] In a preferred embodiment, each end plate 1 is provided with at least one hanging ear 9 for connecting with the boat support, so that the carrier can be placed on the boat support through the hanging ears 9 provided on the two end plates 1.

[0064] It should be understood that the number of the hanging ears 9 in each end plate 1 can be one or two, but is not limited thereto. For example, each end plate 1 is provided with two hanging ears 9, and the two hanging ears 9 are arranged in parallel in the middle of the end plate 1.

[0065] In a preferred embodiment, the spliced carrier is made of quartz material, silicon carbide or ceramic material, and is more suitable for working in a high-temperature environment.

[0066] On this basis, in order to avoid deformation and facilitate cutting the card slots 4, each end plate 1 and each hanging ear 9 are made of silicon carbide material, and each groove rod 2 is made of quartz material.

[0067] To better understand the spliced carrier provided by the present invention, the following takes the spliced carrier having four groove rods 2 as an example for elaboration:

[0068] Please refer to Figures 1 to 10, the spliced vehicle provided by this preferred embodiment includes a left end plate 11, a right end plate 12, two upper groove rods 21 and two lower groove rods 22.

[0069] As Figure 2 shown, the left end plate 11 is vertically arranged. There are two left hanging ears 91 arranged in parallel in the middle of the left end plate 11, two first upper hole positions 61 arranged in parallel in the upper part of the left end plate 11, and two first lower hole positions 62 arranged in parallel in the lower part of the left end plate 11.

[0070] As Figure 3 shown, the right end plate 12 is vertically arranged. There are two right hanging ears 92 arranged in parallel in the middle of the right end plate 12, two second upper hole positions 63 arranged in parallel in the upper part of the right end plate 12, and two second lower hole positions 64 arranged in parallel in the lower part of the right end plate 12.

[0071] Among them, the first upper hole position 61 corresponds to the second upper hole position 63 one by one, and the first lower hole position 62 corresponds to the second lower hole position 64 one by one.

[0072] As Figure 4 , Figure 5 and Figure 6 shown, in each upper groove rod 21, a first upper clamping shaft 51 and a second upper clamping shaft 52 are respectively arranged at both ends of the upper groove rod 21. A plurality of upper groove slots 41 are arranged at intervals along the length direction of the upper groove rod body 201. The opening direction of the upper groove slot 41 is downward, and the upper groove slot 41 is in the shape of ︺.

[0073] As Figure 7 , Figure 8 and Figure 9 shown, in each lower groove rod 22, a first lower clamping shaft 53 and a second lower clamping shaft 54 are respectively arranged at both ends of the lower groove rod 22. A plurality of lower groove slots 42 are arranged at intervals along the length direction of the lower groove rod body 202. The opening direction of the lower groove slot 42 is upward, and the lower groove slot 42 is in the shape of ︺.

[0074] After splicing, the first upper clamping shafts 51 of the two upper groove rods 21 are correspondingly clamped with the two first upper hole positions 61 of the left end plate 11, and the second upper clamping shafts 52 of the two upper groove rods 21 are correspondingly clamped with the two second upper hole positions 63 of the left end plate 11; the first lower clamping shafts 53 of the two lower groove rods 22 are correspondingly clamped with the two first lower hole positions 62 of the left end plate 11, and the second lower clamping shafts 54 of the two lower groove rods 22 are correspondingly clamped with the two second lower hole positions 64 of the left end plate 11. At this time, the opening directions of the upper groove slots 41 of the two upper groove rods 21 are oppositely arranged with the opening directions of the lower groove slots 42 of the two lower groove rods 22, jointly forming a space for accommodating the silicon wafer 3.

[0075] As Figure 5 , Figure 6As shown, in each upper groove bar 21, the first upper clamping shaft 51 and the second upper clamping shaft 52 are horizontally arranged (i.e., horizontally), and the upper groove bar body 201 is inclined. Specifically, the included angle between the axis of the first upper clamping shaft 51 and the axis of the upper groove bar body 201 is θ1, and the included angle between the axis of the second upper clamping shaft 52 and the axis of the upper groove bar body 201 is θ2, where θ1 = θ2 = 2° - 8°.

[0076] As Figure 8 、 Figure 9 shown, in each lower groove bar 22, the first lower clamping shaft 53 and the second lower clamping shaft 54 are horizontally arranged (i.e., horizontally), and the lower groove bar body 202 is inclined. Specifically, the included angle between the axis of the first lower clamping shaft 53 and the axis of the lower groove bar body 202 is θ3, and the included angle between the axis of the second lower clamping shaft 54 and the axis of the lower groove bar body 202 is θ4, where θ3 = θ4 = 2° - 8°.

[0077] As Figure 10 shown, since the inclination angles of the upper groove bar body 201 and the lower groove bar body 202 are 2° - 8°, the included angle between the silicon wafer 3 clamped between the upper card slot 41 and the lower card slot 42 and the left end plate 11 or the right end plate 12 is θ5, where θ5 = 2° - 8°.

[0078] As Figure 5 、 Figure 6 shown, in each upper groove bar 21, there are two opposite first outer positioning planes 71 on the outside of the first upper clamping shaft 51, and two opposite second outer positioning planes 72 on the outside of the second upper clamping shaft 52. Correspondingly, there are two opposite first inner positioning planes on the inside of each first upper hole position 61 in the left end plate 11, and two opposite second inner positioning planes on the inside of each second upper hole position 63 in the right end plate 12. Among them, the first outer positioning plane 71 is in one-to-one fit with the first inner positioning plane, and the second outer positioning plane 72 is in one-to-one fit with the second inner positioning plane, preventing the first upper clamping shaft 51 and the second upper clamping shaft 52 of the upper groove bar 21 from rotating relative to the left end plate 11 and the right end plate 12 respectively.

[0079] As Figure 8 、 Figure 9As shown in the figure, in each lower slot bar 22, two opposite third outer positioning planes 73 are provided on the outer side of the first lower clamping shaft 53, and two opposite fourth outer positioning planes 74 are provided on the outer side of the second lower clamping shaft 54. Correspondingly, two opposite third inner positioning planes are provided on the inner side of each first lower hole position 62 in the left end plate 11, and two opposite fourth inner positioning planes are provided on the inner side of each second lower hole position 64 in the right end plate 12. Among them, the third outer positioning plane 73 is in one-to-one correspondence and fits with the third inner positioning plane, and the fourth outer positioning plane 74 is in one-to-one correspondence and fits with the fourth inner positioning plane, preventing the first lower clamping shaft 53 and the second lower clamping shaft 54 of the lower slot bar 22 from rotating relative to the left end plate 11 and the right end plate 12 respectively.

[0080] The left end plate 11, the right end plate 12, each left hanging ear 91 and each right hanging ear 92 are all made of silicon carbide material, and each upper slot bar 21 and each lower slot bar 22 are all made of quartz material.

[0081] Compared with the prior art, the spliced carrier provided by the present invention has at least the following beneficial effects:

[0082] 1. By providing clamping shafts at both ends of the slot bar and hole positions on the end plate, the connection between the slot bar and the end plate of the carrier is realized by splicing; and, compared with the prior art in which a hook is clamped with a groove, by clamping the clamping shaft of the slot bar with the hole position of the end plate, the clamping shaft and the hole position are in close contact, having higher positioning accuracy, better connection reliability and higher bearing capacity, reducing the displacement or falling off of the slot bar due to loosening or vibration, and it is not easy for the slot position of the slot bar to shift, so as to ensure that the slot bar with the processed slot does not affect the automatic insertion and unloading of the chip after being spliced with the end plate, better replacing the integrated carrier design of first overall welding and then processing the slot, and thus reducing the processing difficulty and production cost.

[0083] 2. By arranging the end plate vertically, the clamping shaft horizontally and the slot bar body obliquely, it is applicable to the setting of the silicon wafer perpendicular to the furnace mouth cross-section direction. Under the same aperture condition, more silicon wafers can be placed, while meeting better processes and ensuring the connection reliability between the end plate and the slot bar.

[0084] 3. By providing an outer positioning plane on the clamping shaft and an inner positioning plane on the hole position, the outer positioning plane and the inner positioning plane are in close contact, preventing the slot bar from rotating relative to the end plate, and thus avoiding the shift of the slot position of the slot bar.

[0085] The following is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
