Description

Technical Field

[0001] This invention relates to the field of passivated solar cell feeding, and more particularly to a method and equipment for stacking solar cells. Background Technology

[0002] In the cross-sectional passivation process of battery cell slabs, multiple battery cell slabs need to be stacked in the material box and their cross-sections should face one side and be exposed to facilitate uniform passivation and improve passivation efficiency.

[0003] In related technologies, a new patent with application number 2024202979148 discloses a sheet carrier and a passivation device. The sheet carrier includes a supporting body and a cavity. During the feeding process using the sheet carrier, the sheet carrier operator stacks multiple battery cells one by one in the supporting body. The supporting body then extends into the cavity through the first opening and forms a gap with the first opening, which facilitates the passivation gas to pass through the gap to coat the multiple stacked battery cells. However, during the movement of the sheet carrier, it is impossible to avoid at least one of the multiple stacked battery cells from shifting or tilting. This can lead to the cross-section passivation of the battery cell cells being prone to circumferential coating, thus reducing the light-receiving area of ​​the battery cell cells. Summary of the Invention

[0004] The purpose of this invention is to provide a method and equipment for stacking battery cells to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for passivated solar cells, comprising a feeding box, a feeding platform, a cell transfer mechanism, and a transfer mechanism. The feeding box includes a feeding box body and a pressing component. The pressing component is movably disposed on the feeding box body, and one end of the pressing component extends into the bearing space of the feeding box body. The feeding platform is used to carry multiple stacked solar cells to form a solar cell group. When the cell transfer mechanism moves the solar cell group to the bearing space, the pressing component moves away from the solar cell group. When the transfer mechanism moves the feeding box carrying the solar cell group, one end of the pressing component presses the solar cell group into the feeding box body.

[0010] Preferably, the pressing assembly further includes multiple guide rods and multiple springs. The multiple guide rods are slidably engaged with the material box body. One end of each guide rod passes through the material box body and is connected to the pressing plate. The multiple springs are correspondingly sleeved on the multiple guide rods and elastically contact the material box body and the pressing plate.

[0011] Preferably, the lifting transmission component slides in conjunction with the guide hole of the material box body, and one of the pressing plate and the material box body is provided with a buckle, while the other is provided with a buckle groove. When one end of the pressing component presses the battery pack into the bearing space, the buckle engages with the buckle groove.

[0012] Preferably, it further includes a locking member and a first lifting drive member. The first lifting drive member is disposed on the transfer mechanism or the cell transfer mechanism. The locking member is disposed on the driving end of the first lifting drive member. When the transfer mechanism grabs the material box carrying the battery cell group, the first lifting drive member drives the locking member to move to engage with the lifting transmission member. The lifting transmission member drives the pressing plate to press the battery cell group in the material box body.

[0013] Preferably, one of the material box body and the transfer mechanism is provided with a limiting hole, and the other is provided with a limiting rod.

The telescopic drive and the second lifting drive allow at least a portion of the transport fork to move within the clearance grooves.

[0015] This application also discloses a method of use, applicable to the above-mentioned feeding equipment for passivated solar cells, the method of use including:

[0020] The technical solution adopted in this application can achieve the following beneficial effects:

[0021] On the one hand, in the passivation cell feeding equipment disclosed in this application, the material box includes a material box body and a pressing component. The pressing component is movably disposed on the material box body, and one end of the pressing component extends into the bearing space of the material box body. The material loading platform is used to carry multiple stacked cells to form a cell group. When the cell group is transported to the bearing space by the cell transfer mechanism, the pressing component moves away from the cell group. When the material box carrying the cell group is transported by the transfer mechanism, one end of the pressing component presses the cell group into the material box body.

[0022] During the use of the passivation cell loading equipment, the loading platform can carry multiple cells stacked sequentially to form a cell group. The cell transfer mechanism moves the cell group from the loading platform to the carrying space of the cell box body. At this time, the pressing component is away from the cell group, thus leaving space to avoid interference with the moving mechanism's movement. When the transfer mechanism grabs the cell box, one end of the pressing component extends into the carrying space and presses the cell group to ensure that the cell group is fixed relative to the cell box.

[0023] The passivation cell loading equipment completes the loading work by carrying and transporting the cell boxes and cell groups through a loading platform, a cell handling mechanism, and a transfer mechanism. During the loading process, the pressing component cooperates with the cell box body to prevent relative displacement of the cell segments after loading, ensuring the neatness of the stacked cell segments. This, in turn, prevents excessive plating of the cell segments in the subsequent passivation process, thus ensuring that the light-illuminated area of ​​the cell segments is not reduced.

[0024] On the other hand, this application also discloses a method of use applicable to the above-mentioned feeding equipment for passivated solar cells, the disclosed method of use including:

[0025] Multiple solar cells are stacked on a loading platform to form a solar cell group. A cell transfer mechanism moves the solar cell group to a carrying space and presses the component away from the solar cell group.

[0026] In this step, the loading platform can carry multiple cell packs, which can be arranged in an array or in a circle, and this application does not impose any restrictions on this. Moreover, when the cell transfer mechanism moves the cell packs into the carrying space, the pressing component moves away from the cell packs, providing sufficient clearance for the cell transfer mechanism.

[0027] One end of the pressing component presses the battery cell pack into the carrying space, and the transfer mechanism transports the material box and battery cell pack to the loading station.

[0028] In this step, the pressing component presses the battery cell group to fix it relative to the material box, preventing relative displacement and skew of at least one of the battery cells in the group, thereby ensuring that the illumination area of ​​the battery cell group will not be reduced. The feeding station can be a passivation station, a passivation waiting station, etc., and this application does not impose any restrictions on it. Attached Figure Description

Detailed Implementation

[0038] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0039] It should be noted that when a component is said to be "set on" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] like Figures 1 to 7 As shown, this application discloses a feeding device for solar cells to be passivated. The disclosed feeding device for solar cells to be passivated includes a material box 100, a material carrier 200, a cell transfer mechanism 300, and a transfer mechanism 400.

[0042] Specifically, the material box 100 includes a material box body 110 and a pressing component 120. The pressing component 120 is movably disposed on the material box body 110, and one end of the pressing component 120 extends into the carrying space of the material box body 110. The material carrier platform 200 is used to carry multiple stacked battery cells to form a battery cell group. When the cell transfer mechanism 300 moves the battery cell group to the carrying space, the pressing component 120 moves away from the battery cell group. When the transfer mechanism 400 moves the material box 100 carrying the battery cell group, one end of the pressing component 120 presses the battery cell group into the material box body 110.

[0043] During the use of the passivation cell loading equipment, the loading platform 200 can carry multiple cell stacks to form a cell group. The cell transfer mechanism 300 moves the cell group from the loading platform 200 to the carrying space of the cell box body 110. At this time, the pressing component 120 is away from the cell group, thus leaving clearance space so that the moving mechanism 300 can move without interference. When the transfer mechanism 400 grabs the cell box 100, one end of the pressing component 120 extends into the carrying space and presses the cell group to ensure that the cell group is fixed relative to the cell box 100.

[0044] The passivation cell loading equipment completes the loading work by carrying and transporting the cell box 100 and the cell group through the loading platform 200, the cell handling mechanism 300 and the transfer mechanism 400. During the loading process, the pressing component 120 cooperates with the cell box body 110 to ensure that the cell segments do not have relative displacement after loading, thus ensuring the neatness of the stacking of multiple cell segments. This ensures that the cell segments do not have excessive plating in the subsequent passivation process, thereby ensuring that the light-illuminated area of ​​the cell segments does not decrease.

[0045] In this embodiment, the pressing assembly 120 may include a lifting transmission component and a pressing plate 122. Specifically, the lifting transmission component is movably mounted on the material box body 110, and the pressing plate 122 is located in the bearing space. The transmission end of the lifting transmission component extends into the bearing space and is connected to the pressing plate 122. The lifting transmission component can be driven by a drive motor, cylinder, electric cylinder, or manually, so that the pressing plate 122 can press the battery pack into the material box body 110 when the transfer mechanism 400 is transporting the material box 100 carrying the battery pack. The structure is simple and easy to install.

[0046] In a first optional embodiment, the lifting transmission component may include a screw 121, a connecting plate 123, and a guide post assembly 124. Specifically, the connecting plate 123 is threadedly engaged with one end of the screw 121, and the other end of the screw 121 is rotatably connected to the material box body 110. One end of the guide post assembly 124 is connected to the connecting plate 123, and the guide post assembly 124 is slidably engaged with the material box body 110. The other end of the guide post assembly 124 is connected to the pressing plate 122, and a plurality of guide posts in the guide post assembly 124 are arranged around the screw 121.

[0047] During the use of the pressing assembly 120, the connecting plate 123 moves up and down with the rotation of the screw 121. When the connecting plate 123 is raised, the guide column assembly 124 is raised and moved with the connecting plate 123, and the pressing plate 122 is raised and moved with the guide column assembly 124, so that the pressing plate 122 can avoid the handling action of the cell transfer mechanism 300 without interference. When the connecting plate 123 is lowered, the guide column assembly 124 is lowered and moved with the connecting plate 123, and the pressing plate 122 is lowered and moved with the guide column assembly 124 to press the battery cell assembly into the bearing space.

[0048] In a further technical solution, the guide post assembly 124 can slide with the connecting plate 123. One end of the guide post assembly 124 can be limited and engaged with the connecting plate 123 along its sliding direction. The other end of the guide post assembly 124 can be floatingly connected to the pressing plate 122. The pressing assembly 120 can also include multiple support rods 126, multiple guide rod sleeves 125, and multiple springs. Specifically, one end of the multiple support rods 126 is connected to the connecting plate 123, the multiple guide rod sleeves 125 are disposed on the material box body 110, the other end of the multiple support rods 126 corresponds to the multiple guide rod sleeves 125 and extends into the bearing space to be floatingly connected to the pressing plate 122, and the multiple springs are correspondingly sleeved on one end of the multiple support rods 126, and the two ends of the springs elastically contact the limiting platform of the guide rod sleeve 125 and the pressing plate 122, respectively.

[0049] During the use of the pressing assembly 120, the connecting plate 123 moves up and down with the rotation of the screw 121. When the connecting plate 123 is raised, the guide post assembly 124 is limited to the connecting plate 123 along its sliding direction. The guide post assembly 124 moves up with the connecting plate 123, and the pressing plate 122 moves up with the guide post assembly 124, so that the pressing plate 122 can avoid the handling action of the cell transfer mechanism 300 without interference. When the connecting plate 123 is lowered, the multiple support rods 126 move down with it. The guide post assembly 124 slides with the connecting plate 123, thereby providing guidance in the pressing direction. At the same time, the pressing plate 122 is driven to move down by the spring force, so that the pressing plate 122 can move a floating allowance distance to press further, pressing the battery cell pack in the bearing space, thereby improving the pressing effect.

[0050] In the second alternative, the lifting transmission component can be a screw 121. Specifically, a pressing plate 122 is connected to a bearing at one end of the screw 121, and the screw 121 is threaded into the material box body 110. The pressing plate 122 extends into the material box body 110. Rotation of the screw 121 drives the pressing plate 122 to move, thereby achieving the action of the pressing plate 122 moving away from or pressing the battery cell assembly. Of course, the pressing plate 122 is connected to a rotating bearing at one end of the screw 121 so that the pressing plate 122 moves only with the rotation of the screw 121, avoiding interference between the pressing plate 122 and other components.

[0051] In a further technical solution, the pressing assembly 120 may also include multiple guide rods and multiple springs. Specifically, the multiple guide rods are slidably engaged with the material box body 110, with one end of each guide rod passing through the material box body 110 and connected to the pressing plate 122. Multiple springs are correspondingly sleeved on the multiple guide rods and elastically contact the material box body 110 and the pressing plate 122. The guide rods guide the movement accuracy of the pressing plate 122, and the springs can provide elastic force to the contact area of ​​the pressing plate 122 through their own elastic potential energy, thereby further increasing the pressing force of the pressing component and ensuring the neatness of the stacked battery cells.

[0052] Of course, the spring can also be sleeved on the guide rod and elastically contact the limiting platform between the material box body 110 and the guide rod, so that the contact between the pressing plate 122 and the battery pack is always surface contact. The spring can use its own elastic potential energy to provide buffer for the pressing force of the pressing plate 122 to achieve the effect of flexible pressing, thereby ensuring the pressing effect of the pressing component on the battery pack and avoiding the battery pack from breaking.

[0053] In the third alternative, the lifting transmission component can slide and engage with the guide hole of the material box body 110. One of the pressing plate 122 and the material box body 110 can be equipped with a buckle, and the other can have a buckle slot. When one end of the pressing component 120 presses the battery pack into the bearing space, the buckle engages with the buckle slot. This buckle-slot engagement directly limits and relatively fixes the pressing plate 122 in pressing the battery pack, and unlocking the buckle engagement is also relatively convenient.

[0054] In the embodiments of this application, the disclosed passivation cell loading equipment may further include a locking member 500 and a first lifting drive member. Specifically, the first lifting drive member is disposed on the transfer mechanism 400 or the cell handling mechanism 300, and the locking member 500 is disposed on the driving end of the first lifting drive member. When the transfer mechanism 400 grabs the material box 100 carrying the cell pack, the first lifting drive member drives the locking member 500 to move to cooperate with the lifting transmission member. The lifting transmission member drives the pressing plate 122 to press the cell pack in the material box body 110.

[0055] The above structure uses locking component 500 and first lifting drive component to enable pressing plate 122 to automatically press the battery cell pack when the material box 100 carries the battery cell pack, thereby realizing the automated design of the battery cell loading equipment to be passivated.

[0056] In addition, the locking component 500 can be an electric clamp, an electric screwdriver, a lifting cylinder, or an electric cylinder, etc., and this application does not impose any restrictions on it; the first lifting drive component can be a cylinder, an electric cylinder, a servo motor, etc., and this application does not impose any restrictions on it.

[0057] In this embodiment, one of the material box body 110 and the transfer mechanism 400 may have a limiting hole A, and the other may have a limiting rod 600. Specifically, when the transfer mechanism 400 is transporting the material box 100 carrying the battery cell pack, one end of the limiting rod 600 extends into the limiting hole A and is limited and engaged, thereby facilitating the transfer mechanism 400 to transport the material box 100.

[0058] Of course, the transfer mechanism 400 can also be a specific structure combined with a transport gripper, such as a transmission gantry or a multi-axis robot, and this application does not impose any restrictions on this.

[0059] In this embodiment, the sheet handling mechanism 300 may include a telescopic drive member 310, a transport fork 320, and a second lifting drive member 330. Specifically, the second lifting drive member 330 is located at the drive end of the telescopic drive member 310, and the transport fork 320 is located at the drive end of the second lifting drive member 330. Both the bearing end of the loading platform 200 and the bearing end of the material box body 110 are provided with clearance grooves. The telescopic drive member 310 and the second lifting drive member 330 allow at least a portion of the transport fork 320 to move within the clearance grooves. The second lifting drive member 330 may be a cylinder, an electric cylinder, a servo motor, etc., and this application does not impose any limitations on this.

[0060] During the use of the passivation cell loading equipment, the telescopic drive 310 drives the second lifting drive 330 and the transport fork 320 to approach the loading platform 200. At least part of the transport fork 320 can pass through the hollow part of the material box body 110 or move directly to the loading platform 200. At least part of the transport fork 320 extends into the clearance groove. The second lifting drive 330 drives the transport fork 320 to lift the battery cell group carried by the bearing end of the loading platform 200. The telescopic drive 310 then drives the second lifting drive 330 and the transport fork 320 to approach the material box 100 and transport the battery cell group. At least part of the transport fork 320 falls into the clearance groove, so that the bearing end of the material box body 110 carries the battery cell group.

[0061] Of course, in an alternative embodiment, the cell transfer mechanism 300 may include a telescopic drive 310, a transport component, and a second lifting drive 330. The transport component may be a gripper that can grip both sides of the cell pack for transport.

[0062] This application also discloses a method of use, applicable to the above-mentioned feeding equipment for passivated solar cells, the disclosed method of use including:

[0063] Multiple solar cells are stacked on the loading platform 200 to form a solar cell group. The cell transfer mechanism 300 transports the solar cell group to the carrying space and presses the component 120 away from the solar cell group.

[0064] In this step, the loading platform 200 can carry multiple battery cell packs, which can be arranged in an array or in a circle. This application does not impose any restrictions on this. Moreover, when the cell transfer mechanism 300 moves the battery cell packs to the carrying space, the pressing component 120 moves away from the battery cell packs to provide sufficient clearance for the cell transfer mechanism 300.

[0065] One end of the pressing component 120 presses the battery cell pack into the carrying space, and the transfer mechanism 400 transports the material box 100 and the battery cell pack to the loading station.

[0066] In this step, the pressing component 120 presses the battery cell group to fix it relative to the material box 100, so as to prevent relative displacement and skew of at least one of the battery cell groups, thereby ensuring that the illumination area of ​​the battery cell group will not be reduced. The material loading station can be a passivation station, a passivation waiting station, etc., and this application does not impose any restrictions on it.

[0067] In a further technical solution, the step of pressing one end of the pressing component 120 into the bearing space to press the battery cell pack includes:

[0068] The first lifting drive component drives the locking component 500 to move to engage with the lifting transmission component, and the lifting transmission component drives the pressing plate 122 to press the battery pack into the bearing space.
