Description

Technical Field

[0001] This application relates to the field of solar photovoltaic cell production, specifically a press, a handling mechanism, and a cell stringing device. Background Technology

[0002] A battery string typically consists of battery cells and solder ribbons, with the ribbons connecting adjacent cells. During battery cell stringing, to prevent the solder ribbons from shifting on the cells, a pressure fixture is usually used to position them. A typical pressure fixture includes a frame and multiple rows of pressure pins mounted below the frame. Each row of pressure pins contains multiple spaced-apart pressure pins that press the solder ribbons one-to-one onto the battery cells, thus positioning the solder ribbons.

[0003] In the prior art, there is also a type of battery string with an adhesive film. This type of battery string has an adhesive film attached to the outside of the solder strip, which covers and bonds the solder strip to the surface of the battery cells. When using a conventional press with pins for positioning this type of battery string with an adhesive film, the press cannot fully press the film in place because the pins in the pin row are spaced apart and the contact area between the pins and the adhesive film is small, thus affecting the adhesion of the adhesive film to the solder strip. Utility Model Content

[0004] This application addresses the problem of poor film application effect of existing presses by providing a press, a handling mechanism, and a battery stringing device with better application effect.

[0005] The technical solution of this application is as follows:

[0006] In a first aspect, this application provides a clamping fixture for use in a battery stringing device for connecting battery cells in series. The clamping fixture includes a frame, an elastic component, and at least two first floating components; wherein:

[0007] The first floating assembly includes a first floating pressure plate and a first flexible layer. The first flexible layer covers the bottom surface of the first floating pressure plate. Each first floating pressure plate extends along a first horizontal direction and is spaced apart along a second horizontal direction.

[0008] Each first floating pressure plate is connected to the bottom of the frame by means of an elastic component that can float up and down.

[0009] In use, the press in this application presses the adhesive film and the solder strip onto the battery cell by aligning the first floating pressure plate with the solder strip extending along the first horizontal direction. The first floating pressure plate and the adhesive film are in surface contact, which can fully contact the adhesive film and enhance the pressing effect of the press on the adhesive film. The elastic component allows each first floating pressure plate to float up and down, thereby ensuring that each first floating pressure plate can effectively press the adhesive film and solder strip below when pressing down, ensuring the final bonding effect of the adhesive film to the solder strip.

[0010] Optionally, the frame is provided with light-transmitting gaps at least at positions corresponding to the positions between two adjacent first floating pressure plates.

[0011] By setting light-transmitting gaps in the frame, light can pass through the gaps to heat the solar cells. When the solar cells are heated, they heat the adhesive film, causing the adhesive film to release its stickiness and adhere to the solar cells.

[0012] Optionally, a first guide groove is provided on the bottom surface of the frame for each first floating pressure plate, and the first floating pressure plate slides in cooperation with the first guide groove when it floats.

[0013] By opening a first guide groove on the bottom surface of the frame, the first guide groove guides the first floating pressure plate as it floats up and down, thus preventing the first floating pressure plate from swaying during floating.

[0014] Optionally, the press further includes two second floating components, each of which includes a second floating pressure plate and a second flexible layer, the second flexible layer covering the bottom surface of the second floating pressure plate;

[0015] The second floating pressure plate extends along the second horizontal direction, and the two second floating pressure plates are located on both sides of each first floating pressure plate in the first horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction.

[0016] Each second floating pressure plate is mounted vertically below the frame via an elastic component.

[0017] By setting two second floating components at both ends of each first floating component below the frame, the two sides of the adhesive film can be flattened, preventing the adhesive film between two adjacent first floating pressure plates from arching, thus making the adhesive film flatter.

[0018] Optionally, a second guide groove is provided on the bottom surface of the frame for each second floating pressure plate, and the second floating pressure plate slides in cooperation with the second guide groove when it floats.

[0019] By opening a second guide groove on the bottom surface of the frame, the second guide groove guides the second floating pressure plate as it floats up and down, thus preventing the second floating pressure plate from swaying during floating.

[0020] Optionally, in its natural state, the second flexible layer is higher than the first flexible layer of the elastic component.

[0021] When placing the pressure tool of this application onto the solder strip and adhesive film, the leading end of the solder strip is still held by the clamp of the solder strip laying mechanism. The solder strip laying mechanism can only release the leading end of the solder strip after the pressure tool has pressed down on it to avoid misalignment of the solder strip. By setting the height of the second flexible layer to be higher than that of the first flexible layer, during the pressing process, by controlling the descent height of the pressure tool, it can be ensured that the first flexible layer is pressed onto the adhesive film and solder strip first, while the second flexible layer is higher than the leading end of the solder strip. This achieves both pressing and positioning of the adhesive film and solder strip, and prevents the leading end of the solder strip, which is in a raised state, from being deformed. When the solder strip laying mechanism releases the leading end of the solder strip, the pressure tool is controlled to continue descending, so that the second flexible layer finally presses onto the leading end of the adhesive film and solder strip, thereby effectively preventing the solder strip from lifting up.

[0022] Optionally, the elastic component includes guide posts and elastic elements. The frame and the first floating pressure plate or the frame and the second floating pressure plate are respectively movably connected through guide posts. The elastic element is sleeved on the guide posts. The first end of the elastic element abuts against the frame, and the second end of the elastic element abuts against the first floating pressure plate or the second floating pressure plate. The elastic element causes the first floating pressure plate or the second floating pressure plate to move away from the frame.

[0023] A specific configuration of the elastic component is provided, which can easily realize the up-and-down floating of the first floating pressure plate and the second floating pressure plate, ensuring that the first floating pressure plate and the second floating pressure plate can better press the adhesive film and the welding strip onto the battery cell.

[0024] Optionally, guide holes are provided at the positions corresponding to the frame and each elastic component, and the guide holes are used to install guide posts and elastic components.

[0025] By creating guide holes in the frame, the guide holes can serve as guides and positions when the guide posts and elastic elements are installed inside them.

[0026] Optionally, the first flexible layer is provided with a weld strip clearance groove extending along the first horizontal direction.

[0027] By setting a solder strip clearance groove on the first flexible layer, the solder strip can be accommodated in the clearance groove when the first flexible layer is pressed against the adhesive film, so that the adhesive film can better adhere to the battery cell.

[0028] Optionally, the first flexible layer and the second flexible layer are anti-stick layers, or the working surfaces of the first flexible layer and the second flexible layer are coated with an anti-stick coating.

[0029] The first flexible layer and the second flexible layer are made of anti-stick or have an anti-stick coating to prevent the first flexible layer and the second flexible layer from sticking to the adhesive film.

[0030] Secondly, this application provides a handling mechanism, including a first picking component, a second picking component and a third picking component, wherein the first picking component and the third picking component are arranged side by side at intervals, and the second picking component is arranged inside the first picking component;

[0031] The first pickup component is configured to pick up and release the frame of the first aspect of the clamp;

[0032] The second pickup assembly is configured to pick up and release the adhesive film located below the presser;

[0033] The third pickup component is configured to pick up and release the battery cells.

[0034] By setting three picking components in the handling mechanism to pick up the press, adhesive film and battery cell respectively, the press, adhesive film and battery cell can be transported and laid synchronously, improving the efficiency of laying battery strings with adhesive film; while the press adopts the first floating pressure plate to contact the adhesive film, which expands the contact area between the press and the adhesive film and enhances the pressing effect of the press on the adhesive film.

[0035] Thirdly, this application provides a battery stringing device, including a conveying mechanism, a ribbon laying mechanism, and a handling mechanism as described in the second aspect; wherein:

[0036] The handling mechanism is mounted above the conveying mechanism and is configured to place battery cells at the input end of the conveying mechanism;

[0037] The ribbon laying mechanism is configured to lay ribbon onto the solar cells;

[0038] The handling mechanism is also configured to simultaneously pick up the press and the adhesive film, lay the adhesive film on the welding strip, and place the press on the adhesive film so that the press positions the adhesive film and the welding strip on the battery cell, wherein the first floating pressure plate presses each welding strip one by one.

[0039] The battery cells are transported by a conveying mechanism, the welding strip is laid by a welding strip laying mechanism, and the adhesive film is laid on the welding strip by a handling mechanism and the press is placed on the adhesive film. This completes the positioning of the adhesive film and welding strip before the battery strings with adhesive film are strung together, preparing for the stringing of the battery strings. The press uses a first floating pressure plate to contact the adhesive film, which expands the contact area between the press and the adhesive film and enhances the pressing effect of the press on the adhesive film.

[0053] The conveying mechanism 2 includes a first picking component 201, a second picking component 202, and a third picking component 203. Detailed Implementation

[0054] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] like Figures 1-5 As shown, this application provides a press 1, which is applied in a battery stringing device for connecting battery cells in series, and is used to press the adhesive film and the solder strip 103 in the battery string with adhesive film onto the battery cells at the same time.

[0056] The press 1 includes a frame 10, an elastic component 20, and at least two first floating components 30.

[0057] The first floating component 30 includes a first floating pressure plate 31 and a first flexible layer 32. The first flexible layer 32 covers the bottom surface of the first floating pressure plate 31. Each first floating pressure plate 31 extends along a first horizontal direction 101 and is spaced apart along a second horizontal direction 102. The second horizontal direction 102 is perpendicular to the first horizontal direction 101. Each first floating pressure plate 31 is vertically and buoyantly connected to the bottom of the frame 10 via an elastic component 20.

[0058] The number of first floating pressure plates 31 can be set one-to-one according to the number of solder strips 103 on the surface of each battery cell in the battery string, so that each first floating pressure plate 31 presses down one solder strip 103 in one-to-one correspondence.

[0059] In use, the pressure fixture 1 of this application has a first floating pressure plate 31 corresponding to each welding strip 103. By aligning the first floating pressure plate 31 with the welding strip 103 extending along the first horizontal direction 101 and pressing it down, the adhesive film and welding strip 103 can be pressed onto the battery cell. The first floating pressure plate 31 and the adhesive film have a surface contact area, which is large and can fully contact the adhesive film, thus enhancing the pressing effect of the pressure fixture 1 on the adhesive film. The elastic component 20 allows each first floating pressure plate 31 to float up and down, thereby ensuring that each first floating pressure plate 31 can effectively press the adhesive film and welding strip 103 below when pressing down, ensuring the final adhesion effect of the adhesive film to the welding strip 103. The first flexible layer 32 on the bottom surface of the first floating pressure plate 31 ensures that the adhesive film along the entire welding strip 103 is fully pressed onto the battery cell, while also reducing the force of the first floating pressure plate 31 on the battery cell and avoiding microcracks in the battery cell.

[0060] Optionally, the frame 10 is a cuboid, with its length direction being the second horizontal direction 102 and its width direction being the first horizontal direction 101.

[0061] In one embodiment, optionally, a light-transmitting gap 11 is provided on the frame 10 at least at a position corresponding to the position between two adjacent first floating pressure plates 31. A light-transmitting gap 11 may also be provided on the outer side of the outermost first floating pressure plate 31. The light-transmitting gap 11 allows light from one side of the frame 10 to pass through and reach the other side of the frame 10.

[0062] By setting a light-transmitting gap 11 on the frame 10, light can pass through the light-transmitting gap 11 to heat the battery cell. After the battery cell is heated, it heats the entire adhesive film, causing the adhesive film to release its stickiness and adhere to the battery cell.

[0063] In another embodiment therein, such as Figure 5 As shown, optionally, a first guide groove 12 is provided on the bottom surface of the frame 10 corresponding to each first floating pressure plate 31, and the first floating pressure plate 31 slides in cooperation with the first guide groove 12 when it floats.

[0064] By opening a first guide groove 12 on the bottom surface of the frame 10, the first guide groove 12 guides the first floating pressure plate 31 when it floats up and down, which can prevent the first floating pressure plate 31 from swaying when it floats.

[0065] As an optional implementation, the press 1 also includes two second floating components 40, each of which includes a second floating pressure plate 41 and a second flexible layer 42, the second flexible layer 42 covering the bottom surface of the second floating pressure plate 41;

[0066] The second floating pressure plate 41 extends along the second horizontal direction 102, and the two second floating pressure plates 41 are located on both sides of each first floating pressure plate 31 in the first horizontal direction 101.

[0067] Each second floating pressure plate 41 is mounted below the frame 10 by means of an elastic component 20, which can float up and down.

[0068] By setting two second floating components 40 at both ends of each first floating component 30 below the frame 10, the two sides of the adhesive film can be flattened, preventing the adhesive film between two adjacent first floating pressure plates 31 from arching, thus making the adhesive film flatter.

[0069] In one embodiment, optionally, a second guide groove is provided on the bottom surface of the frame 10 corresponding to each second floating pressure plate 41, and the second floating pressure plate 41 slides in cooperation with the second guide groove when it floats.

[0070] By opening a second guide groove on the bottom surface of the frame 10, the second guide groove guides the second floating pressure plate 41 when it floats up and down, which can prevent the second floating pressure plate 41 from swaying when it floats.

[0071] In this embodiment, optionally, in its natural state, the second flexible layer 42 of the elastic component 20 is higher than the first flexible layer 32.

[0072] When the pressure tool 1 of this application is placed on the solder ribbon 103 and the adhesive film, the leading end of the solder ribbon 103 is still held by the clamp of the solder ribbon laying mechanism. The solder ribbon laying mechanism can only release the leading end of the solder ribbon 103 after the pressure tool 1 presses down on the solder ribbon 103 to avoid misalignment of the solder ribbon 103. By setting the height of the second flexible layer 42 to be higher than that of the first flexible layer 32, during the pressing process of the pressure tool 1, by controlling the descent height of the pressure tool 1, it can be ensured that the first flexible layer 32 is pressed onto the adhesive film and the solder ribbon 103 first, while the second flexible layer 42 is higher than the leading end of the solder ribbon 103. This achieves both pressing and positioning of the adhesive film and the solder ribbon 103 and prevents the leading end of the solder ribbon 103, which is in a raised state, from being deformed. When the solder ribbon laying mechanism releases the leading end of the solder ribbon 103, the pressure tool 1 is controlled to continue to descend, so that the second flexible layer 42 finally presses onto the adhesive film and the leading end of the solder ribbon 103, thereby effectively preventing the solder ribbon 103 from lifting up.

[0073] As an optional implementation, the elastic component 20 includes guide posts and an elastic element. The frame 10 and the first floating pressure plate 31, or the frame 10 and the second floating pressure plate 41, are respectively movably connected via guide posts. The elastic element is sleeved on the guide posts, with its first end abutting against the frame 10 and its second end abutting against the first floating pressure plate 31 or the second floating pressure plate 41. The elastic element causes the first floating pressure plate 31 or the second floating pressure plate 41 to move away from the frame 10. Optionally, the elastic element is a spring. Optionally, the first floating pressure plate 31 and the second floating pressure plate 41 are respectively mounted on the frame 10 via at least two sets of springs and guide posts.

[0074] This embodiment provides a specific configuration of the elastic component 20, which can easily realize the up-and-down floating of the first floating pressure plate 31 and the second floating pressure plate 41, ensuring that the first floating pressure plate 31 and the second floating pressure plate 41 better press the adhesive film and the welding strip 103 onto the battery cell.

[0075] In one embodiment, optionally, guide holes (not shown in the figure) are provided at the positions corresponding to the frame 10 and each elastic component 20, and the guide holes are used to install guide posts and elastic components.

[0076] By opening guide holes in the frame 10, the guide holes can play a guiding and positioning role when the guide post and elastic element are installed in the guide holes.

[0077] As an optional implementation, the first flexible layer 32 is provided with a weld strip clearance groove extending along the first horizontal direction 101.

[0078] By providing a solder ribbon clearance groove on the first flexible layer 32, when the first flexible layer 32 presses against the adhesive film, the solder ribbon 103 can be accommodated in the solder ribbon clearance groove, so that the adhesive film can better adhere to the battery cell.

[0079] In one embodiment, optionally, the first flexible layer 32 and the second flexible layer 42 are anti-stick layers, or the working surfaces of the first flexible layer 32 and the second flexible layer 42 are coated with an anti-stick coating.

[0080] When the first flexible layer 32 and the second flexible layer 42 are made of anti-stick layers, they have their own anti-stick function; or the working surfaces of the first flexible layer 32 and the second flexible layer 42 have an anti-stick coating (e.g., grease layer) to prevent the first flexible layer 32 and the second flexible layer 42 from sticking to the adhesive film.

[0081] Optionally, the first flexible layer 32 and the second flexible layer 42 can be made of materials such as silicone or rubber.

[0082] like Figure 6 As shown, this application also provides a handling mechanism 2 for handling the components and tooling required for stringing battery strings with adhesive film, namely, solder strip 103, adhesive film, battery cells and press 1.

[0083] The handling mechanism 2 includes a first picking component 201, a second picking component 202 and a third picking component 203. The first picking component 201 and the third picking component 203 are arranged side by side with intervals, and the second picking component 202 is arranged inside the first picking component 201.

[0084] The first pickup component 201 is configured to pick up and release the frame 10 in the aforementioned pressure fixture 1 embodiment;

[0085] The second pickup assembly 202 is configured to pick up and release the adhesive film located below the pressure fixture 1;

[0086] The third pickup component 203 is configured to pick up and release the battery cell.

[0087] Optionally, the first pickup component 201 is a magnetic suction component, with magnets provided at both ends of the frame 10. The magnetic suction component attracts the magnets, thereby attracting the pressure fixture 1. The second pickup component 202 and the third pickup component 203 can be suction cups, which respectively attract the adhesive film and the battery cell.

[0088] By setting three picking components in the handling mechanism 2 to pick up the press 1, the adhesive film and the battery cell respectively, the press 1, the adhesive film and the battery cell can be transported and laid synchronously, which improves the efficiency of laying the battery string with the adhesive film; while the press 1 uses the first floating pressure plate 31 to contact the adhesive film, which expands the contact area between the press 1 and the adhesive film and enhances the pressing effect of the press 1 on the adhesive film.

[0089] This application also provides a battery stringing device, including a conveying mechanism, a ribbon laying mechanism, and the aforementioned handling mechanism 2.

[0090] Wherein: the handling mechanism 2 is installed above the conveying mechanism and is configured to place the battery cell at the input end of the conveying mechanism;

[0091] The ribbon laying mechanism is configured to lay ribbon 103 onto the solar cell;

[0092] The handling mechanism 2 is also configured to simultaneously pick up the presser 1 and the adhesive film, lay the adhesive film on the welding strip 103, and place the presser 1 on the adhesive film so that the presser 1 positions the adhesive film and the welding strip 103 on the battery cell, wherein the first floating pressure plate presses each welding strip 103 one by one.

[0093] The conveying mechanism and the welding strip laying mechanism can adopt any available structure in the prior art.

[0094] The battery cells are transported by a conveying mechanism, the welding ribbon 103 is laid by a welding ribbon laying mechanism, and the adhesive film is laid on the welding ribbon 103 by a handling mechanism and the press 1 is placed on the adhesive film. This completes the positioning of the adhesive film and the welding ribbon 103 before the battery string with adhesive film is strung together, preparing for the stringing of the battery string. The press 1 uses a first floating pressure plate to contact the adhesive film, which expands the contact area between the press 1 and the adhesive film and enhances the pressing effect of the press 1 on the adhesive film.

[0095] The foregoing has provided a sufficiently detailed and specific description of this application. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application.
