Abstract
Description
Technical Field
[0001] The embodiments of this application relate to the field of photovoltaic cell production equipment technology, and more specifically, this application relates to a boat support and bearing device. Background Technology
[0002] Vapor phase deposition (CVD) is a technology that utilizes physical and chemical processes occurring in the gas phase to alter the surface composition of a workpiece, forming a metal or compound coating with specific properties. Chemical vapor deposition (CVD) is a process that uses gaseous or vaporous substances to undergo chemical reactions on the surface of a silicon wafer, generating a solid deposit. The TOPCon cell process mainly involves three thin film deposition routes: LPCVD, PECVD, and ALD. LPCVD is currently the primary technology for TOPCon thin film deposition, possessing excellent step coverage, high film quality, controllable film composition and structure, low gas consumption, and reliance on heating equipment as a heat source to maintain the reaction, thus reducing particulate contamination sources.
[0003] In LPCVD (Liquid Crystallization) processes, solar cells requiring specific processing are placed in boats, with one cell positioned in each slot of the boat. These slots are typically vertically oriented. To prevent damage from collisions with the slot openings during placement, the width of the slot must be greater than the thickness of the cell. This results in inconsistent tilt angles of the cells in different slots, leading to poor consistency in the surface film formation between the cells. Utility Model Content
[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, the present invention provides a boat support and bearing device to ensure that, without the need for a separately designed complex boat structure for longitudinally placing the battery cells, the problem of poor film formation consistency caused by the battery cells tilting in different directions is avoided.
[0005] To solve the above problems, the technical solution adopted in this application is as follows:
[0006] On one hand, this application discloses a boat support for supporting a small boat. The boat support includes a first side plate and a second side plate arranged opposite to each other. The upper surfaces of the first side plate and the second side plate are respectively provided with a plurality of pairs of support grooves along the length direction. Each pair of support grooves includes a first support groove on the first side plate and a second support groove on the second side plate. The first support groove and the second support groove respectively have a support surface for supporting the boat ears of the small boat. The support surfaces of the first support groove and the second support groove have a height difference, which makes the boat body tilted, thereby causing the battery cells inside the small boat to tilt towards the same side.
[0007] The first and second support grooves, arranged in pairs with a height difference, via the first and second side plates, tilt the supporting boat, causing the solar cells inside the boat to tilt towards the same side, ensuring the consistency of solar cell deposition during the vapor deposition process. This design can accommodate both vertical and horizontal solar cell insertion processes, balancing loading and unloading efficiency without requiring a complex boat structure specifically designed for vertical solar cell insertion.
[0008] In one embodiment, both bearing surfaces are at a preset angle to the horizontal plane, with the preset angle being 3° to 15°.
[0009] The tilt angle of the boat is controlled by a preset angle between the bearing surface and the horizontal plane, ensuring the effectiveness of the vapor deposition process while the battery cells inside the boat tilt to the same side.
[0010] In one embodiment, the bearing surface of the first side plate is parallel to the bearing surface of the second side plate.
[0011] By using two parallel bearing surfaces, both sides can have the same tilt angle, ensuring that the boat ears on both sides can fully contact the bearing surfaces and ensuring that the boat is set up stably.
[0012] In one embodiment, the bearing surface of the first side plate is coplanar with the bearing surface of the second side plate.
[0013] The coplanar bearing surfaces ensure that the boat's lugs fully contact and abut with the two bearing surfaces, allowing it to be placed stably in the first and second bearing grooves, thus improving the overall stability of the boat.
[0014] In one embodiment, the boat support also includes:
[0015] End plate, the end plate connects the ends of the first side plate and the second side plate located on the same side;
[0016] A connecting plate is connected to the middle of both the first and second side plates.
[0017] The end plates and connecting plates form a stable structure between the first side plate and the second side plate, preventing relative displacement between them.
[0018] In one embodiment, the first side plate, the second side plate, the end plate, and the connecting plate are provided with hollowed-out areas.
[0019] By setting hollow areas in the end plates, connecting plates, first side plates, and second side plates, the overall weight of the boat support is reduced.
[0020] In one embodiment, the boat support also includes:
[0021] A baffle is attached to the end plate and extends outward.
[0022] The baffle design on the end plate of the boat carrier facilitates the boat carrier being grasped by the handling robot or supported by the carrier platform.
[0023] On the other hand, this application also discloses a supporting device, which includes a boat support for supporting a small boat. The small boat includes a hull and a pair of boat lugs. The hull includes:
[0024] First base plate;
[0025] Second base plate;
[0026] Multiple grooved bars, with their two ends connected to the first base plate and the second base plate, respectively;
[0027] A pair of boat ears are respectively connected to the first base plate and the second base plate, or a pair of boat ears are respectively connected to the groove bars located on two opposite sides;
[0028] A pair of boat ears rest on the bearing surfaces of the first bearing groove and the second bearing groove, respectively.
[0029] The support groove and the lugs work together to tilt the supporting boat, causing the solar cells inside the boat to tilt towards the same side. Furthermore, the boat can be adapted to both vertical and horizontal solar cell insertion processes simply by adjusting the position of the lugs, eliminating the need for two different boat structures.
[0030] In one embodiment, the hull further includes:
[0031] A limiting protrusion is connected to the outer side of the first base plate and / or the second base plate, and abuts against the first side plate and / or the second side plate respectively.
[0032] The limiting protrusions support the boat body on the inner side of the first and second side plates, thereby keeping the tilted boat body stable and preventing it from wobbling.
[0033] In one embodiment, the surfaces of the grooved bars arranged opposite to each other are provided with a plurality of placement grooves;
[0034] Multiple placement slots are distributed along the length of the slotted bar, and the positions of the placement slots on different slotted bars correspond one-to-one.
[0035] The placement slots of different grooved bars are arranged one-to-one with each other, so that when the boat is placed normally on the plane, the solar cells it carries are in a vertical and horizontal state, which facilitates the loading and unloading of solar cells.

[0046] 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, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0047] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a boat support 2 for supporting small boats 1. The boat support 2 includes a first side plate 21 and a second side plate 22 arranged opposite to each other, and an end plate 23. The end plate 23 connects the ends of the first side plate 21 and the second side plate 22 located on the same side, thereby fixing the first side plate 21 and the second side plate 22. The upper surfaces of the first side plate 21 and the second side plate 22 are respectively provided with multiple pairs of bearing grooves along the length direction. Each small boat 1 can be placed in one pair of bearing grooves. The boat support 2 can hold multiple small boats 1 at the same time. The specific number of bearing grooves can be designed according to actual process requirements.
[0048] In this embodiment, each pair of support grooves includes a first support groove 211 on the first side plate 21 and a second support groove 221 on the second side plate 22. The first support groove 211 and the second support groove 221 each have a support surface 200 for supporting the boat ear 12 of the small boat 1. There is a height difference between the support surfaces 200 of the first support groove 211 and the second support groove 221, which causes the small boat 1 to tilt, thereby causing the battery cells inside the small boat 1 to tilt towards the same side, ensuring the consistency of the deposition effect of each battery cell in the vapor deposition process.
[0049] Furthermore, to ensure that the solar cells inside the boat tilt towards the same side while also considering the effectiveness of the vapor deposition process, the tilt angle of the boat 1 can be arbitrarily selected from the range of 3° to 15°, for example, 4°, 6.7°, 10°, 14°, and 15°. Corresponding to the structure of the first support groove 211 and the second support groove 221, the support surface 200 is used to support the boat lugs 12 of the boat 1, and both support surfaces form an angle of 3° to 15° with the horizontal plane. Specifically, the support surface 200 of the first side plate 21 and the support surface 200 of the second side plate 22 are parallel to each other, ensuring that their tilt angles are the same. To ensure sufficient contact area for the boat lugs 12 of the boat 1 when placed on the support surface 200, the support surfaces 200 of the first side plate 21 and the second side plate 22 are coplanar, improving the stability of the boat 1 when placed as a whole.
[0050] In other embodiments, the boat support 2 also includes a connecting plate 24, which is connected to the middle of the first side plate 21 and the second side plate 22, thereby strengthening the fixation of the first side plate 21 and the second side plate 22 and preventing relative displacement between them, which would cause the boat support 2 to deform.
[0051] In other embodiments, the boat carrier 2 also includes a baffle 25, which is connected to the end plate 24 and extends outward to facilitate the boat carrier 2 being grasped by a handling robot or carried by a support platform.
[0052] Furthermore, in order to reduce the overall weight of the boat support 2, the first side plate 21, the second side plate 22, the end plate 23, and the connecting plate 24 are all provided with hollow areas.
[0053] like Figure 3 , Figure 4 and Figure 5As shown, based on the boat support 2 in the above embodiment, this embodiment also provides a supporting device, which includes a boat support 2 for supporting a small boat 1. The small boat 1 includes a boat body 11 and a pair of boat ears 12. The boat body 11 includes a first base plate 111, a second base plate 112, and a plurality of slotted rods 113. In this embodiment, there are four slotted rods 113, but this utility model is not limited thereto. The two ends of the slotted rods 113 are respectively connected to the first base plate 111 and the second base plate 112, serving to connect and fix the first base plate 111 and the second base plate 112. At the same time, the surfaces of the slotted rods 113 that are arranged opposite to each other are provided with a plurality of placement slots 1131 along the length direction. The positions of the placement slots 1131 of different slotted rods correspond one-to-one, so that when the boat body is placed normally on a plane, the battery cells it carries are in a vertical and horizontal state, thereby allowing the battery cells to be placed normally in the placement slots 1131 in a horizontal and vertical direction, reducing the difficulty of picking up and placing the battery cells and improving efficiency.
[0054] A pair of boat lugs 12 are respectively connected to the first base plate 111 and the second base plate 112. Thus, when the boat lugs 12 are placed on the support surface 200, the solar cells are in a vertical position. At this time, due to the height difference between the two support surfaces 200, all solar cells are tilted to the same side. When it is necessary to place the solar cells horizontally, simply connect the pair of boat lugs 12 to the slot bars 113 located on the two opposite sides. At this time, the solar cells are pressed against the lower side of the placement slots 1131 on both sides under their own weight. Therefore, the posture of all solar cells is still the same, and there is no need to design a complex boat structure specifically for the vertical and horizontal insertion process of solar cells.
[0055] like Figure 5 As shown, in other embodiments, since the boat 1 is placed at an angle on two supporting surfaces, in order to prevent the boat 1 from swaying or shifting, the boat body 11 in this embodiment also includes a limiting protrusion 114. The limiting protrusion 114 is connected to the outer side of the first bottom plate 111 and / or the second bottom plate 112, and abuts against the inner side of the first side plate 21 and / or the second side plate 22 respectively, so as to keep the tilted boat body stable and avoid relative sliding.
