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 passivation cassette. Background Technology

[0002] In the processing and production of solar cells, the cut edges of the diced cells need to be passivated. Before passivation, they need to be placed in a passivation box. Existing passivation boxes in the industry typically include at least a base plate, a top cover plate, and two side plates. A stack of cells to be passivated is placed within the space formed by the base plate, top cover plate, and two side plates. During passivation, a gap exists between the surface of the topmost cell and the top cover plate, leading to contamination from process gas spray during the passivation process. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a passivated material box, which can prevent adjacent battery cells from sticking together due to photoresist formation, and ensure smooth and orderly sliding.

[0004] To solve the above problems, the technical solution adopted in this application is as follows:

[0005] A passivation box includes a base plate, two first side plates, and a top cover assembly. The two first side plates are respectively mounted on two opposite short sides of the base plate along a first horizontal direction. The top cover assembly includes at least one guide pin and an upper plate and a lower plate arranged vertically. The two ends of the upper plate are respectively mounted on the upper ends of the two first side plates. The lower end of the guide pin is fixedly mounted on the lower plate. The upper plate is provided with at least one through hole corresponding to the position of the guide pin. The upper end of the guide pin movably passes through the through hole. The two edges of the lower plate parallel to a second horizontal direction abut against the inner surfaces of the two first side plates. The second horizontal direction is perpendicular to the first horizontal direction.

[0006] The passivation box provided in this application has a cover assembly that includes a vertically movable lower plate. When the cover assembly is fastened to the top of the passivation box, the lower plate can descend vertically and cover the upper surface of the first cell, preventing the cell surface from being contaminated by the sprayed process gas during passivation.

[0007] Optionally, the passivation box further includes at least one first spring, each first spring being sleeved on a corresponding guide pin, with the first end of the first spring abutting against the lower surface of the upper plate and the second end of the first spring abutting against the upper surface of the lower plate.

[0008] By setting a first spring to move the lower plate away from the upper plate, the lower surface of the lower plate is pressed against the upper surface of the uppermost solar cell, further reducing the gap between the two.

[0009] Optionally, the passivation box also includes an assembly component, with at least one assembly component provided on the upper end of the outer side surface of each first side plate. The assembly component is used to fix the edge of the upper plate so that the edge of the upper plate abuts against the upper end of the corresponding first side plate.

[0010] By setting up the assembly components, the top cover assembly can be stably fixed to the top of the two first side plates during process handling or transportation, preventing the top cover assembly from losing contact with the two first side plates.

[0011] Optionally, the assembly includes a fixing block, a rotating shaft, and a hook plate. The fixing block is disposed on the outer wall of the first side plate and has a receiving groove. The hook plate is rotatably disposed in the receiving groove via the rotating shaft. The rotation axis of the hook plate is parallel to the second horizontal direction. The upper end of the hook plate extends toward the upper plate to form a hooking part, which is used to snap onto the edge of the upper plate when it is close to the upper plate.

[0012] By setting a fixed block, a rotating shaft, and a hook plate, the hook plate can fasten or loosen the edge of the upper plate after rotation. The structure is simple, easy to maintain, and has a low cost.

[0013] Optionally, the lower end of the hook plate forms a limiting protrusion in the direction away from the first side plate. The assembly also includes a second spring, the upper end of which abuts against the limiting protrusion and the lower end of which abuts against the fixing block. The second spring is used to push the limiting protrusion to rotate the hook plate, thereby causing the hook part to be pressed against the edge of the upper plate.

[0014] By setting a second spring that causes the hook plate to rotate, the hook part is driven to move toward the edge of the upper cover plate and finally snaps onto the edge of the upper cover plate.

[0015] Optionally, the fixing block is provided with a limiting member located above the limiting protrusion, the limiting member being used to limit the upward travel of the limiting protrusion.

[0016] By setting a limiting component to intercept the limiting protrusion, the travel limit of the limiting protrusion is restricted, thus preventing the hook plate from rotating excessively under the action of the spring.

[0017] Optionally, the hook part is made of magnetic material, and a magnet is provided at the position corresponding to the hook part on the edge of the upper plate. The magnet is used to attract the hook part.

[0018] By incorporating magnets, the magnetic material hooks can be easily attached to the edge of the upper panel under magnetic force.

[0019] Optionally, the passivation box also includes a wear-resistant block corresponding to the position of the hook part. The wear-resistant block is fixedly embedded in the upper surface edge of the upper plate by screws, and the hook part is pressed onto the wear-resistant block at the edge of the upper plate.

[0020] By setting wear-resistant blocks on the edge of the upper plate to contact the hook part, the fastening effect of the assembly components is prevented from being reduced after long-term contact wear. On the other hand, the wear-resistant blocks can be quickly replaced after they are worn, without having to replace the entire upper plate, thus saving costs.

[0021] Optionally, the passivation box also includes at least one positioning pin fixedly disposed on the upper surface of the upper plate, and the lower surface of the base plate is provided with positioning holes for accommodating positioning pins of other passivation boxes and blind holes for accommodating guide pins of other passivation boxes.

[0022] By setting positioning pins on the upper plate and positioning holes and blind holes on the lower plate, the passivation boxes can be positioned to each other when multiple passivation boxes are stacked vertically, preventing the boxes from tipping over and damaging the battery cells.

[0023] Optionally, the upper surface of the upper plate includes a first plane, a second plane, and a third plane in sequence along a first horizontal direction. The hook portion is used to press against the first plane or the third plane. The second plane is higher than the hook portion pressed against the first plane or the third plane. The through hole, the positioning pin, and the guide pin are located on the second plane.

[0024] By setting the second plane in the middle of the upper plate to be higher than the first or third plane on both sides, the second plane can contact the bottom plate of the passivation box above. The contact surface is large, and static friction is used to limit the relative displacement between the passivation boxes, reducing the probability of tipping accidents caused by the movement between the passivation boxes.

[0025] Optionally, the passivation box further includes a pad located on the base plate for supporting the battery cells, the pad being provided with at least one tooth groove for receiving a transport fork tooth, the tooth groove extending along a second horizontal direction; and / or,

[0026] The passivation box also includes two load-bearing pins respectively disposed on the outer surfaces of the two first side plates, the load-bearing pins extending along the first horizontal direction or in the opposite direction of the first horizontal direction.

[0027] A pad with fork-shaped grooves is provided to facilitate the handling mechanism in removing a stack of battery cells from the passivation box; a load-bearing pin is provided to facilitate the handling mechanism in gripping the entire box during movement.

[0028] Optionally, the base plate has a first guide groove extending along the second horizontal direction at both short sides. The bottom of the first guide groove is also provided with at least one first waist hole extending along the first horizontal direction. The lower end of the first side plate matches the shape of the first guide groove. The lower end of the first side plate is adjustablely fixed to the first waist hole by at least screws.

[0029] By setting a first guide groove on the base plate, the first side plate is at least guided and fixed to prevent the first side plate from deflecting; the base plate is also provided with a first waist hole, so that the first side plate can be set at different positions along the first waist hole to adapt to various battery cell sizes.

[0030] Optionally, the passivation box also includes a second side plate, which is disposed at the edge of the base plate, and the two vertical sides of the second side plate respectively contact the two first side plates.

[0031] By setting a second side plate, the edge of one side of the cell can be blocked according to the actual passivation requirements, thus preventing the side plate of the cell that does not need to be passivated from being contaminated by process gases.

[0032] Optionally, the base plate has a second guide groove at the long side of the second side plate. The second guide groove extends along the first horizontal direction. The bottom of the second guide groove is also provided with at least one second waist hole extending along the second horizontal direction. The lower end of the second side plate matches the shape of the second guide groove. The lower end of the second side plate is adjustablely fixed to the second waist hole by at least screws.

[0033] By setting a second guide groove on the base plate, the second side plate is at least guided and fixed to prevent the second side plate from deflecting; the base plate is also provided with a second waist hole, so that the second side plate can be set in different positions along the second waist hole to accommodate various battery cell sizes.

[0034] Optionally, the upper surface of the second side plate is provided with a clearance groove, which extends from the upper surface of the second side plate to the outer side surface of the second side plate, and the middle of the edge of the lower surface of the upper plate away from the second side plate is provided with a mating groove, which extends from the lower surface of the upper plate to the side surface of the upper plate.

[0035] By setting clearance grooves and docking grooves, it is easier for the clamping mechanism to grab the upper plate, thereby making it easier to clamp the entire upper cover assembly.

[0036] Optionally, the upper end of the guide pin is fixedly provided with a limiting part for limiting the downward travel of the guide pin. The limiting part is any one of an outer retaining ring, a retaining ring, a screw, or a protrusion structure formed by the upper end of the guide pin extending radially.

[0037] By setting a limiting part at the upper end of the guide pin, the downward movement of the guide pin is restricted, preventing the guide pin from moving too downward and slipping out of the through hole. Attached Figure Description

[0052] 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.

[0053] Existing passivation boxes in the industry typically include at least a base plate, a top cover plate, and two side plates. A stack of solar cells to be passivated is placed within the space formed by the base plate, top cover plate, and two side plates, with the cut surfaces to be passivated located on the same side or both sides. During passivation, a gap exists between the surface of the topmost solar cell and the top cover plate, leading to contamination from process gas spray during the passivation process.

[0054] To solve this problem, such as Figure 1-2 As shown, this application discloses a passivation box, which includes a base plate 2, two first side plates 3, and a top cover assembly 1. The two first side plates 3 are respectively disposed on two opposite short sides of the base plate 2 along a first horizontal direction. The top cover assembly 1 includes at least one guide pin 11 and an upper plate 12 and a lower plate 13 arranged vertically. The two ends of the upper plate 12 are respectively assembled to the upper ends of the two first side plates 3. The lower end of the guide pin 11 is fixedly installed on the lower plate 13. The upper plate 12 is provided with at least one through hole 125 corresponding to the position of the guide pin 11. The upper end of the guide pin 11 movably passes through the through hole 125. The two edges of the lower plate 13 parallel to the second horizontal direction abut against the inner surfaces of the two first side plates 3, and the second horizontal direction is perpendicular to the first horizontal direction. Wherein, the first horizontal direction is as follows: Figure 1 In the X direction, the second horizontal direction is as follows Figure 1 In the Y direction, both are located in the horizontal plane and are perpendicular to each other. The passivation cartridge of this application will be positioned as follows: Figure 1 The illustration is placed on a horizontal plane.

[0055] The top cover assembly 1 includes an upper plate 12, a lower plate 13, and a guide pin 11. The lower plate 13 is vertically slidable below the upper plate 12 under the guidance of the guide pin 11. When the top cover assembly 1 is placed over the upper ends of the two first side plates 3, the lower plate 13 can slide vertically downwards under at least the force of gravity, until the lower surface of the lower plate 13 finally contacts the surface of the highest-positioned solar cell, thus covering the solar cell surface. During passivation treatment, the sprayed process gases will be less likely to contaminate the surface of the solar cell.

[0056] As the lower shelf 13 decreases in height, the upper end of the guide pin 11 may disengage from the through hole 125. To avoid this, a limiting part is fixedly provided at the upper end of the guide pin 11 to restrict the downward travel of the guide pin. The limiting part can be any one of an outer retaining spring, a retaining ring, a screw, or a protrusion structure formed radially from the upper end of the guide pin 11. The outer retaining spring or retaining ring can be fitted onto the upper end of the guide pin 11. To improve installation stability, the guide pin 11 can be further machined with a mounting groove on its outer surface in the circumferential direction to accommodate the outer retaining spring or retaining ring; or a screw can be used, which can be screwed horizontally into the screw hole of the guide pin 11, or screwed vertically into the screw hole on the upper end face of the guide pin 11. The outer diameter of the nut is larger than the outer diameter of the guide pin 11, so that it abuts against the through hole 125 to achieve limiting; or more conveniently, the guide pin 11 can be machined with a radial protrusion structure during the production stage, which also achieves limiting.

[0057] The guide pin 11 slides along the through hole 125, which may generate significant friction. After prolonged use, this can cause the guide pin to lose its ability to move precisely in the vertical direction, potentially leading to friction and jamming between the side plate of the lower plate 13 and the first side plate 3. To avoid this, a bushing can be installed in the through hole 125. The outer diameter of the guide pin 11 is approximately equal to the inner diameter of the bushing, providing precise guidance while reducing friction and increasing durability. Even if wear occurs, maintenance can be performed by replacing the bushing, without replacing the entire upper plate 12. With the bushing installed in the through hole 125, the limiting part at the upper end of the guide pin 11, as mentioned above, will abut against the bushing to achieve limitation, instead of abutting against the through hole 125.

[0058] To ensure stable contact between the lower plate 13 and the surface of the solar cells, further, as follows... Figure 1 As shown, a first spring 5 is also wound around the pin body of the guide pin 11. The first end of the first spring 5 abuts against the lower surface of the upper plate 12, and the second end of the first spring 5 abuts against the upper surface of the lower plate 13, so that the lower plate 13 is as far away from the upper plate 12 as possible under the elastic force of the first spring 5, which means that the lower plate 13 is stably pressed against the surface of the battery cell, further reducing the possibility of a gap between the surface of the battery cell and the lower surface of the lower plate 13.

[0059] During handling and processing, it is necessary to ensure that the top cover assembly 1 remains continuously positioned over the tops of the two first side panels 3. For example... Figure 3-4 As shown, two assembly components 6 are also provided on the upper end of the outer side of each first side plate 3. Each assembly component 6 is used to fix the edge of the upper plate 12 to the upper end of the corresponding first side plate 3.

[0060] Specifically, assembly component 6 includes a fixing block 61, a rotating shaft 62, and a hook plate 63. The fixing block 61 can be fixedly mounted on the upper outer surface of the first side plate 3 by screws. The fixing block 61 is provided with a receiving groove 64, which extends through the upper surface and side surface of the fixing block 61. The hook plate 63 is rotatably mounted in the receiving groove 64 via the rotating shaft 62. The rotation axis of the hook plate 63 is parallel to the second horizontal direction. The upper end of the hook plate 63 extends toward the upper plate 12 to form a hooking part 631. The style of the hooking part 631 can refer to various hook structures used for fixing, so that after the hook plate 63 rotates and the hooking part 631 moves toward the edge of the upper plate 12, it finally snaps onto the edge of the upper plate 12, preventing the upper cover assembly 1 from falling off. The structures of the fixing block 61, rotating shaft 62, and hook plate 63 are relatively simple, easy to manufacture and maintain, and have low cost.

[0061] Since the hook plate 63 is rotatably mounted on the rotating shaft 62, the hooking part 631 may be close to or far from the edge of the upper plate 12. To ensure that the hooking part 631 is as close as possible to the edge of the upper plate 12, refer to... Figure 3-4 As shown, the lower end of the hook plate 63 forms a limiting protrusion 632 facing away from the first side plate 3. The assembly assembly 6 also includes a second spring 65, which is also provided inside the receiving groove 64. The second spring 65 can be arranged vertically, with its upper end abutting against the limiting protrusion 632 and its lower end abutting against the fixing block 61. The second spring 65 is used to push the limiting protrusion 632 upward, causing the hook plate 63 to rotate around the pivot 62, ultimately bringing the hook part 631 close to and pressing it against the edge of the upper plate 12. This arrangement prevents the hook part 631 from detaching from the top of the first side plate 3 due to other unforeseen reasons after it has engaged with the edge of the upper plate 12, significantly reducing the probability of the battery cell falling and being damaged.

[0062] In addition, to further facilitate the hook part 631 to approach the edge of the upper plate 12, the hook part can be provided with a magnetic material, and a magnet can be provided at the edge of the upper plate 12 and at the position corresponding to the hook part 631. The hook part 631 with magnetic material can approach and fasten to the edge of the upper plate 12 under the action of magnetic force.

[0063] Continue to refer to Figure 4 As shown, the fixing block is also provided with a limiting member 611 located above the limiting protrusion 632. The limiting member 611 is used to limit the upward travel limit of the limiting protrusion 632 and prevent the limiting protrusion 632 from moving excessively under the elastic force of the second spring 65.

[0064] It is foreseeable that, during long-term use, due to different process requirements, the hook part 631 will frequently press against or move away from the edge of the upper plate 12, which may easily cause wear on the pressed-on position of the upper plate 12 edge and reduce the fastening effect. (Reference) Figure 3-5The passivation box also includes a wear-resistant block 7, which is fixed to the edge of the upper surface of the upper plate 12 by screws, and the wear-resistant block 7 corresponds to the hook part 631. This arrangement allows the hook part 631 to contact the wear-resistant block 7 during long-term use. If the wear-resistant block 7 wears and forms a shallow pit, the wear-resistant block 7 can be easily replaced without replacing the entire upper plate 12, thus saving production costs.

[0065] During passivation, multiple passivation cartridges are typically arranged in an array and / or stack within the process chamber. To ensure placement stability during stacking and prevent movement or dropping during infeeding or venting, such as... Figure 1-3 , Figure 5 As shown, the passivation box also includes at least one positioning pin 8 fixedly disposed on the upper surface of the upper plate 12. The positioning pin 8 can be a pointed positioning pin 8; meanwhile, referring to Figure 6-7 The lower surface of the base plate 2 is provided with positioning holes 21 for accommodating positioning pins 8 for accommodating other passivation boxes (passivation boxes located below) and blind holes 22 for accommodating guide pins 11 for accommodating other passivation boxes. When multiple passivation boxes are stacked, adjacent passivation boxes can form a fixed effect on each other, reducing the possibility of movement and thus reducing the risk of accidents.

[0066] To further improve the mutual fixation effect between adjacent boxes during stacking, refer to Figure 5 The upper surface of the upper plate 12 includes at least a first plane 121, a second plane 122, and a third plane 123 sequentially along a first horizontal direction. A hook portion 631 is used to press and fasten the wear-resistant block 7 located on the first plane 121 or the third plane 123. The second plane 122 is higher than the hook portion 631 pressing on the first plane 121 or the third plane 123. The through hole 125, the positioning pin 8, and the guide pin 11 are all located on the second plane 122. Therefore, when multiple passivation boxes are stacked, adjacent passivation boxes will contact each other using the second plane 122 as the contact surface. The second plane 122 has a large area, resulting in greater static friction between adjacent passivation boxes, further improving the fixing effect and thus further reducing the probability of accidents.

[0067] As an optional embodiment, to facilitate the rapid placement or removal of a stack of solar cells to be passivated into or from the passivation cassette, such as... Figure 3 As shown, the passivation box also includes a pad 9 located on the base plate 2 for supporting the battery cells. The pad 9 is provided with at least one tooth groove 91 for accommodating the transport fork teeth. The tooth groove 91 extends along the second horizontal direction. When transport is required, a transport mechanism with transport fork teeth (not shown in the figure, but refer to the fork teeth of a forklift) can extend the transport fork teeth into the tooth groove 91 of the pad 9 and use the pad 9 to lift a stack of battery cells.

[0068] In automated passivation processes, it is sometimes necessary to move the entire passivation cartridge, such as... Figure 1-3 As shown, a load-bearing pin 10 is provided on the outer surface of the first side plate 3. The load-bearing pin 10 extends along the first horizontal direction, so that the mechanism for moving the entire passivation box can hook the load-bearing pin 10 and move it.

[0069] Considering that the cell located in the passivation box may only have one side of its fracture surface requiring passivation treatment, optionally, such as Figure 1-2 As shown, the passivation box also includes a second side plate 4, which is disposed on the edge of the bottom plate 2. The two vertical sides of the second side plate 4 are in contact with the two first side plates 3 respectively. When the top cover assembly 1 is fastened to the top of the first side plate 3, the top of the second side plate 4 is also in contact with the upper plate 12. The second side plate 4 shields the edge of the battery cell that does not need to be passivated, preventing it from being contaminated by process gases.

[0070] At certain predetermined times, the passivation cartridge will be removed from the cover assembly 1, while referring to... Figure 2 and Figure 5 The upper surface of the second side plate 4 is provided with a clearance groove 41, which extends from the upper surface of the second side plate 4 to the outer side surface of the second side plate 4; the lower surface of the upper plate 12 is provided with a docking groove 124 at the middle of the edge away from the second side plate 4, which extends from the lower surface of the upper plate 12 to the side surface of the upper plate 12. The clearance groove 41 and the docking groove 124 facilitate the opening mechanism (not shown in the figure) to contact and clamp and raise the upper plate 12, thereby raising the upper cover assembly 1 away from the upper end of the first side plate 3, which facilitates the insertion and removal of the entire stack of battery cells.

[0071] Considering that the solar cells to be processed may include different sizes, such as Figure 8-10 The base plate 2 has a first guide groove 23 extending along the second horizontal direction at both short sides. The base plate also has at least one first waist hole 24 extending along the first horizontal direction. The bottom end of the first side plate 3 is shaped to fit the first guide groove 23. The lower end of the first side plate is fixed in the first waist hole 24 by at least screws.

[0072] For the same reason, refer to Figure 10-11 The base plate 2 has a second guide groove 25 on the long side of the second side plate 4. The second guide groove 25 extends along a first horizontal direction, and at least one second waist hole 26 extending along a second horizontal direction is provided at the bottom of the second guide groove 25. The lower end of the second side plate 4 is shaped to fit the second guide groove 25, and the lower end of the second side plate 4 is adjustablely fixed to the second waist hole 26 by at least screws. This arrangement allows the second side plate 4 to be guided and adjustablely fixed at the edge of the base plate 2, accommodating various battery cell sizes, while also preventing the second side plate 4 from deflecting.
