Description

Battery string gluing device and battery string production equipment Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production, and specifically to a cell string gluing device and cell string production equipment. Background Art

[0002] When stringing busbar-less cells, the lack of a busbar on the cells leads to poor bonding between the cells and the ribbons. This can easily lead to partial or complete detachment of the ribbons from the cells, impacting normal module production. To reinforce the bond between the cells and the ribbons, the industry has proposed applying glue to the post-weld cell strings, applying the glue to the ribbons, and then using the glue to adhere the ribbons to the cells.

[0003] After applying glue to the first surface of a battery string, current battery string gluing devices use a flipping mechanism to pick up the battery string and flip it 180°. The flipping mechanism then moves the battery string under the gluing device for gluing to the second surface (the side facing away from the first surface). This flipping mechanism typically uses a suction cup or plate to hold the battery string, while a linear module drives its translation. This makes it difficult to maintain a horizontal position while the suction cup or plate is lifting the battery string for gluing. Furthermore, the linear module's translation of the battery string can easily cause the battery string to wobble, affecting the accuracy and quality of gluing. Summary of the Invention

[0004] In order to solve the problems existing in the traditional battery string gluing device, this application provides a battery string gluing device, and its detailed technical solution is as follows:

[0005] A battery string gluing device includes a first conveying line, a first gluing mechanism, a transport mechanism, a second conveying line, and a second gluing mechanism, wherein:

[0006] The first conveyor line is configured to convey the battery strings to be glued to the first glue application station and the handling station in sequence along a first horizontal direction, wherein the length direction of the battery strings is parallel to the first horizontal direction;

[0007] The first glue applying mechanism is provided at the first glue applying station and is located above the first conveyor line, and the first glue applying mechanism is configured to apply glue to the first surface of the battery string;

[0008] The transport mechanism is provided at the transport station, and is configured to pick up the battery string on which the first surface gluing is completed and located at the transport station, flip the battery string, and then transport the battery string to the second conveyor line;

[0009] The second conveying line is configured to convey the battery string to the second gluing station;

[0010] The second glue applying mechanism is provided at the second glue applying station and is located above the second conveying line. The second glue applying mechanism is configured to apply glue to the second surface of the battery string.

[0011] The battery string gluing device of the present application is such that after the battery string completes the first surface gluing on the first conveyor line, the conveying mechanism flips the battery string and conveys the flipped battery string to the second conveyor line, and the second conveyor line conveys the flipped battery string to the second gluing station for second surface gluing; using the second conveyor line to carry and convey the battery string to implement the second surface gluing can ensure that the battery string remains in a horizontal state, avoids the battery string from shaking during the conveying process, and thus improves the second surface gluing effect.

[0012] In some embodiments, the second conveyor line includes a conveyor belt, a supporting base plate and an adsorption assembly, wherein: adsorption holes are provided on the conveyor belt; the supporting base plate is provided below the conveying surface of the conveyor belt, and the supporting base plate is configured to support the conveying surface of the conveyor belt; the adsorption assembly is installed on the supporting base plate, and the adsorption assembly is configured to adsorb the battery string through the adsorption holes.

[0013] By setting up the second conveyor line, the second conveyor line can suck the battery string tightly during the conveying and gluing process to prevent the battery string from deviating, and effectively support the battery string during the gluing process to ensure the gluing effect of the second surface of the battery cell.

[0014] In some embodiments, the first conveying line includes a first conveying section and a second conveying section located behind the first conveying section, wherein the first gluing station is located on the conveying path of the first conveying section, and the handling station is located on the conveying path of the second conveying section; the structure of the first conveying section is the same as that of the second conveying line.

[0015] The first conveyor section is configured to securely hold the battery string during conveying and gluing, preventing it from straying. It also effectively supports the string during gluing, ensuring gluing of the first surface of the cell. The second conveyor section is used only to transport the cell after gluing on the first surface to the handling station. No gluing is required during conveying. Therefore, the second conveyor section can use a standard conveyor belt, eliminating the need for a support base plate and suction components, thus saving costs on the first conveyor line.

[0016] In some embodiments, the battery string gluing device further includes a first aligning mechanism, which is disposed at a transport station and configured to perform position correction on the battery string transported to the transport station.

[0017] The first aligning mechanism aligns the battery strings before transporting, realizes the position correction of the battery strings, ensures that the transport mechanism can smoothly pick up and flip the battery strings, and accurately transport the battery strings to the second conveyor line.

[0018] In some embodiments, the first regularizing mechanism includes a first regularizing plate, a second regularizing plate, a first regularizing drive assembly and a second regularizing drive assembly, wherein: the first regularizing plate and the second regularizing plate are relatively arranged on both sides of the first conveyor line, and the length directions of the first regularizing plate and the second regularizing plate are parallel to the first horizontal direction; the first regularizing drive assembly and the second regularizing drive assembly are both fixed relative to the first conveyor line, the first regularizing plate is installed at the drive end of the first regularizing drive assembly, and the second regularizing plate is installed at the drive end of the second regularizing drive assembly, and the first regularizing drive assembly and the second regularizing drive assembly are configured to simultaneously drive the first regularizing plate and the second regularizing plate to move relative to each other along the second horizontal direction to push the side of the battery string conveyed to the handling station and perform position correction on the battery string, and the second horizontal direction is perpendicular to the first horizontal direction.

[0019] By setting up the first regularizing mechanism and the second regularizing mechanism, the first regularizing mechanism and the second regularizing mechanism push the battery string located at the handling station from both sides of the first conveyor line, thereby realizing the position correction of the battery string and ensuring that the length direction of the battery cell is parallel to the first horizontal direction.

[0020] In some embodiments, the transport mechanism includes a flipping part and a conveying part, wherein: the flipping part is configured to pick up the battery string that has completed the first surface gluing and is located at the transport station, and flip the battery string, and the flipping part is also configured to place the flipped battery string onto the conveying surface of the conveying part; the output end of the conveying part is connected to the input end of the second conveyor line, and the conveying part is configured to convey the battery string to the second conveyor line.

[0021] After the flipping unit completes flipping the battery string, it places the battery string on the conveying surface of the conveying unit, and the conveying unit directly conveys the battery string to the second conveyor line. After flipping, there is no need to pick up the battery string a second time, thereby reducing the risk of damage to the battery string.

[0022] In some embodiments, the battery string gluing device further includes a second aligning mechanism, which is disposed at the transport station and configured to correct the position of the battery string on the conveying portion.

[0023] The second regularizing mechanism corrects the position of the battery string before printing the glue on the second surface, so as to ensure the glue application effect of the second glue application mechanism on the second surface of the battery string.

[0024] In some embodiments, the conveying part and the second conveying line are located above the first conveying line, and the conveying direction of the conveying part and the second conveying line is opposite to the conveying direction of the first conveying line; the flipping part is configured to lift the picked-up battery string above the conveying surface of the conveying part, and drive the battery string down so that the battery string falls onto the conveying surface of the conveying part.

[0025] The conveying portion and the second conveying line are arranged above the first conveying line, and the conveying directions of the conveying portion and the second conveying line are set to be opposite to the conveying direction of the first conveying line, thereby reducing the overall size of the battery string gluing device of the present application.

[0026] In some embodiments, the flipping part includes a lifting drive unit, a lifting frame, a flipping frame, a flipping drive unit and a suction assembly, wherein: the lifting frame is connected to the driving end of the lifting drive unit, the flipping frame is rotatably connected to the lifting frame, and the flipping frame is transmission-connected to the flipping drive unit provided on the lifting frame; the suction assembly includes a plurality of suction cups spaced along a first horizontal direction on the flipping frame; the lifting drive unit is configured to drive the suction assembly to descend so that the suction assembly adsorbs the battery string from the handling station; the flipping drive unit is configured to drive the suction assembly to flip, so as to drive the battery string adsorbed on the suction assembly to flip, so that the second surface of the battery string faces upward; the lifting drive unit is also configured to drive the suction assembly to rise so as to lift the flipped battery string above the conveying surface of the conveying part, and drive the suction assembly to descend so that the battery string falls onto the conveying surface of the conveying part.

[0027] By setting the flipping part, the flipping part can absorb the battery string from the transporting station, flip the battery string so that the second surface faces upward, and then place the battery string on the conveying surface of the conveying part.

[0028] In some embodiments, the suction assembly further includes a support plate, which is mounted on the flip frame along a first horizontal direction, and a plurality of suction cups pass through the support plate; after the plurality of suction cups adsorb the battery string, the battery string rests on the support plate.

[0029] By providing a support plate, the battery string sucked by the suction cup is supported to prevent the battery cell and the welding ribbon from being pulled apart due to deformation of the suction cup.

[0030] In some embodiments, the suction component includes a first suction component and a second suction component, the suction surface of the first suction component and the suction surface of the second suction component are opposite to each other, and when the suction surface of the first suction component is flipped downward, the suction surface of the second suction component is flipped upward.

[0031] The first suction assembly and the second suction assembly alternately absorb the battery strings from the handling station, and alternately flip the battery strings to the second surface facing upward and then place them on the conveying surface of the conveying part, thereby improving the flipping and transportation efficiency of the battery strings and ensuring the gluing rhythm of the second gluing mechanism.

[0032] In some embodiments, the conveying part includes a fixed frame, an opening and closing mechanism, a first connecting frame, a second connecting frame, a first conveyor belt and a second conveyor belt, wherein: the opening and closing mechanism is arranged on the fixed frame; the first connecting frame and the second connecting frame are both slidably connected to the bottom of the fixed frame along the second horizontal direction, and are respectively transmission-connected to the opening and closing mechanism, the opening and closing mechanism is configured to drive the first connecting frame and the second connecting frame to slide apart to both sides or slide together to the middle along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the first conveyor belt is installed on the first connecting frame along the first horizontal direction, and the second conveyor belt is installed on the second connecting frame along the first horizontal direction, and a lifting space for the turning part to pass through is formed between the first conveyor belt and the second conveyor belt; when the opening and closing mechanism drives the first connecting frame and the second connecting frame to slide apart to both sides, a lifting space with a first width is formed between the first conveyor belt and the second conveyor belt, and the first width is greater than the width of the battery string, and the turning part lifts the flipped battery string to above the first conveyor belt and the second conveyor belt through the lifting space;

[0033] When the opening and closing mechanism drives the first connecting frame and the second connecting frame to slide toward the middle, a lifting space with a second width is formed between the first conveyor belt and the second conveyor belt. The second width is smaller than the width of the battery string. The flip part descends through the lifting space, causing the battery string to fall onto the first conveyor belt and the second conveyor belt.

[0034] The conveyor section is configured so that the flipping section can lift the flipped battery string above the conveyor surface. When the flipping section returns to its original position, the battery string on the flipping section automatically falls onto the conveyor surface. This eliminates the need for secondary pick-up of the battery string during transfer from the flipping section to the conveyor, thus preventing damage to the battery string.

[0035] In some embodiments, the battery string gluing device also includes a third regularizing plate, a fourth regularizing plate, a third regularizing drive assembly and a fourth regularizing drive assembly, wherein: the third regularizing plate and the fourth regularizing plate are relatively arranged on both sides of the conveying part, and the length direction of the third regularizing plate and the fourth regularizing plate is parallel to the first horizontal direction; the third regularizing drive assembly is installed on the first connecting frame and is driven and connected to the third regularizing plate, and the fourth regularizing drive assembly is installed on the second connecting frame and is driven and connected to the fourth regularizing plate; the third regularizing drive assembly and the fourth regularizing drive assembly are configured to drive the third regularizing plate and the fourth regularizing drive assembly to move relative to each other along the second horizontal direction after the conveying part conveys at least one battery cell in the carried battery string to the second conveyor line, so as to push the side of the battery string carried on the first conveyor belt and the second conveyor belt to correct the position of the battery string.

[0036] When the battery string transitions from the conveyor section to the second conveyor line, misalignment may occur between the battery cells within the battery string. When at least one battery cell in the battery string reaches the second conveyor line, the third and fourth straightening plates, driven in conjunction with the third and fourth straightening drive assemblies, correct the position of the battery string, ensuring that the remaining battery cells in the battery string are aligned with the battery cells on the second conveyor line, thereby eliminating misalignment between the battery cells and ultimately ensuring that the second gluing mechanism effectively applies glue to the second surface of the battery string.

[0037] In some embodiments, the third regular plate includes several elastic plates arranged side by side and spaced apart, and the fourth regular plate is a rigid plate; after the fourth regular drive component drives the fourth regular plate to push the battery string, the third regular drive component drives the third regular plate to push the battery string.

[0038] The rigid fourth regularization plate pushes the battery string first, and the elastic third regularization plate elastically presses against the battery string later; after completing the regularization of the battery string, the elastic third regularization plate retreats first, and the rigid fourth regularization plate retreats later, thus improving the regularization accuracy of the battery string.

[0107] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0108] As shown in FIG1 to FIG3, the battery string gluing device in the embodiment of the present application includes a first conveyor line 1, a first gluing mechanism 2, a transport mechanism 3, a second conveyor line 4 and a second gluing mechanism 5, wherein:

[0109] The first conveyor line 1 is configured to convey the battery strings to be glued to the first gluing station and the handling station in sequence along a first horizontal direction (such as the X-axis direction in FIG1 ), wherein the length direction of the battery strings is parallel to the first horizontal direction.

[0110] The first glue-applying mechanism 2 is disposed at the first glue-applying station and above the first conveyor line 1. The first glue-applying mechanism 2 is configured to apply glue to the first surface of the battery string. The transport mechanism 3 is disposed at the transport station. The transport mechanism 3 is configured to pick up the battery string at the transport station after the first surface glue is applied, flip the battery string, and transport the battery string to the second conveyor line 4.

[0111] The second conveying line 4 is configured to convey the battery string to the second gluing station.

[0112] The second glue applying mechanism 5 is provided at the second glue applying station and is located above the second conveying line 4 . The second glue applying mechanism 5 is configured to apply glue to the second surface of the battery string.

[0113] It can be seen that in the battery string gluing device in the embodiment of the present application, after the battery string completes the gluing of the first surface currently facing upward on the first conveyor line 1, the conveying mechanism 3 flips the battery string over to face the second surface upward, and transports the flipped battery string to the second conveyor line 4, and the second conveyor line 4 transports the battery string to the second gluing station for second surface gluing.

[0114] The second conveyor line 4 is used to carry and convey the flipped battery string to apply glue to the second surface of the battery string, which ensures that the battery string remains horizontal and prevents the battery string from shaking during transportation, thereby improving the gluing effect on the second surface.

[0115] Optionally, the second conveyor line 4 includes a conveyor belt, a support base and an adsorption assembly, wherein: the conveyor belt is provided with adsorption holes. The support base is arranged below the conveying surface of the conveyor belt, and the support base is configured to support the conveying surface of the conveyor belt. The adsorption assembly is mounted on the support base, and the adsorption assembly is configured to adsorb the battery string through the adsorption holes. By configuring the second conveyor line 4 in this way, the second conveyor line 4 can suck the battery string tightly during the conveying and gluing process to prevent the battery string from deviating, and effectively support the battery string during the gluing process, ultimately ensuring the gluing effect of the second gluing mechanism 5 on the second surface of the battery string.

[0116] The first conveyor line 1 needs to convey the battery string to the first gluing station, and needs to continue to convey the battery string that has completed the first surface gluing to the handling station. Therefore, the length of the first conveyor line 1 is much longer than the second conveyor line 4. In order to ensure the gluing effect on the first surface of the battery string and reduce the cost of the first conveyor line 1, optionally, as shown in Figures 1 and 2, the first conveyor line 1 includes a first conveying section 11 and a second conveying section 12 located behind the first conveying section 11, wherein the first gluing station is located on the conveying path of the first conveying section 11, and the handling station is located on the conveying path of the second conveying section 12.

[0117] The structure of the first conveying section 11 is the same as that of the second conveying line 4. In this way, it can ensure that the first conveying section 11 sucks the battery string tightly during the conveying and gluing process to prevent the battery string from deviating, and effectively supports the battery string during the gluing process, thereby ensuring the gluing effect of the first surface of the battery cell.

[0118] Since the second conveying section 12 is only used to convey the battery cells that have completed the first surface gluing to the handling station, no gluing is required during the conveying process. Therefore, the second conveying section 12 can use an ordinary conveyor belt without the need to set up a supporting bottom plate and adsorption components, thereby saving the cost of the first conveyor line 1.

[0119] Optionally, as shown in Figure 15, the battery string gluing device in the embodiment of the present application also includes a first regularizing mechanism 6, which is arranged at the transport station B. The first regularizing mechanism 6 is configured to correct the position of the battery string transported to the transport station B, thereby ensuring that the transport mechanism 3 can smoothly pick up and flip the battery string, and accurately place the flipped battery string on the second conveyor line 4.

[0120] As shown in FIG15 , optionally, the first regularization mechanism 6 includes a first regularization plate 61, a second regularization plate 62, a first regularization drive assembly 63, and a second regularization drive assembly 64, wherein: the first regularization plate 61 and the second regularization plate 62 are relatively arranged on both sides of the first conveyor line 1, and the length direction of the first regularization plate 61 and the second regularization plate 62 is parallel to the first horizontal direction. The first regularization drive assembly 63 and the second regularization drive assembly 64 are both fixedly arranged relative to the first conveyor line 1, the first regularization plate 61 is installed at the driving end of the first regularization drive assembly 63, and the second regularization plate 62 is installed at the driving end of the second regularization drive assembly 64. The first regularization drive assembly 63 and the second regularization drive assembly 64 are configured to simultaneously drive the first regularization plate 61 and the second regularization plate 62 to move relative to each other along the second horizontal direction (such as the Y-axis direction in FIG15 ) to push the side of the battery string conveyed to the handling station A and perform position correction on the battery string. The second horizontal direction is perpendicular to the first horizontal direction.

[0121] It can be seen that by setting up the first aligning mechanism 6, the first aligning mechanism 5 can simultaneously push the battery string located at the handling station from both sides of the first conveyor line 1, thereby ensuring that the length direction of the battery string is restored to be parallel to the first horizontal direction.

[0122] As shown in Figures 6 to 9, the transport mechanism 3 optionally includes a flipping unit 31 and a conveying unit 32, wherein the flipping unit 31 is configured to pick up the battery string that has completed the first surface glue application and flip the battery string at the transport station. The flipping unit 31 is also configured to place the flipped battery string onto the conveying surface of the conveying unit 32. The output end of the conveying unit 32 is connected to the input end of the second conveyor line 4, and the conveying unit 32 is configured to transport the battery string to the second conveyor line 4.

[0123] As can be seen, after flipping the battery string, the flipping unit 31 directly places the battery string onto the conveying surface of the conveying unit 32. The conveying unit 32 then directly transports the battery string to the second conveyor line 4 connected to it. In other words, the handling mechanism 3 only picks up and places the battery string once through the flipping unit 31. After flipping, there is no need to pick up the battery string a second time before transferring it to the second conveyor line 4, thus reducing the risk of damage to the battery string.

[0124] Because the battery string may be shifted during the flipping process, the battery string gluing device in the embodiment of the present application optionally further includes a second aligning mechanism, which is disposed at the transport station and configured to correct the position of the battery string on the conveyor portion 32. That is, by providing the second aligning mechanism, the position of the battery string is corrected before the glue is printed on the second surface of the battery string, thereby ensuring the glue application effect of the second gluing mechanism 5 on the second surface of the battery string.

[0125] Optionally, the conveyor unit 32 and the second conveyor line 4 are located above the first conveyor line 1, and the conveying direction of the conveyor unit 32 and the second conveyor line 4 is opposite to that of the first conveyor line. After the flipping unit 31 flips the picked-up battery string, it lifts the battery string above the conveying surface of the conveyor unit 32 and then drives the battery string down, causing the battery string to fall onto the conveying surface of the conveyor unit 32.

[0126] Positioning the conveyor unit 32 and the second conveyor line 4 above the first conveyor line 1, and setting the conveying direction of the conveyor unit 32 and the second conveyor line 4 opposite to that of the first conveyor line 1, reduces the overall size of the battery string gluing device in this embodiment of the application. The flipping unit 31 places the flipped battery cells onto the conveyor unit 32 by lifting and lowering them, reducing the risk of damage to the battery string.

[0127] As shown in Figures 7 to 10, the flipping portion 31 optionally includes a lifting drive unit 311, a lifting frame 312, a flipping frame 313, a flipping drive unit 314, and a suction assembly 315. The lifting frame 312 is connected to the driving end of the lifting drive unit 311, the flipping frame 313 is rotatably connected to the lifting frame 312, and the flipping frame 313 is in driving connection with the flipping drive unit 314 disposed on the lifting frame 312. The suction assembly 315 includes a plurality of suction cups spaced apart along a first horizontal direction on the flipping frame 313.

[0128] The working process of the turning part 31 is as follows:

[0129] When the first conveyor line 1 conveys the battery string with the first surface glue applied to the transport station, the lifting drive unit 311 drives the suction assembly 315 to descend, so that the suction assembly 315 absorbs and picks up the battery string from the transport station.

[0130] Subsequently, the flip driving unit 314 drives the suction component 315 to flip, thereby causing the battery string adsorbed on the suction component 315 to flip, so that the second surface of the battery string faces upward.

[0131] Next, the lifting drive unit 311 drives the suction assembly 315 to rise so as to lift the flipped battery string to above the conveying surface of the conveying portion 32 .

[0132] Finally, the lifting drive unit 311 drives the suction assembly 315 to descend and return to its original position, so that the battery string falls onto the conveying surface of the conveying portion 32 .

[0133] As shown in Figure 10, the suction assembly 315 optionally further includes a support plate 318, which is mounted on the flip frame 313 along a first horizontal direction, and a plurality of suction cups 317 pass through the support plate 318. After the plurality of suction cups 317 adsorb the battery string, the battery string rests on the support plate 318. By providing the support plate 318, support is provided for the battery string adsorbed by the suction cups 317, and the battery cell and the solder ribbon are prevented from being pulled apart due to deformation of the suction cups 317. In particular, for battery cells without main grids, the connection strength between them and the solder ribbon is relatively small. When the suction cups 317 adsorb the battery cell and deform, it is particularly easy for the battery cell and the solder ribbon to be pulled apart. However, by providing the support plate, the pulling-off phenomenon can be effectively avoided.

[0134] In the embodiment shown in Figure 10, the support plate 318 is a split structure, comprising multiple support plates spaced apart along the first horizontal direction. Each support plate corresponds to a cell in the battery string, and each support plate is provided with a suction cup 317. When the suction cups 317 adhere to the battery string, each cell in the string is supported on a corresponding support plate. Of course, the support plate 318 can also be a single strip extending along the first horizontal direction.

[0135] As shown in Figure 10, the suction assembly 315 is configured as two groups, namely a first suction assembly and a second suction assembly. The suction surface of the first suction assembly and the suction surface of the second suction assembly are opposite each other. When the suction surface of the first suction assembly is flipped downward, the suction surface of the second suction assembly is flipped upward. In this way, the first suction assembly and the second suction assembly can alternately absorb the battery string from the handling station and alternately flip the battery string to the second surface facing upward before placing it on the conveying surface of the conveyor 32, thereby improving the flipping and transportation efficiency of the battery string and ensuring the gluing rhythm of the second gluing mechanism 5.

[0136] As shown in Figures 7 to 9 and 11 to 13, the conveying portion 32 optionally includes a fixed frame 321, an opening and closing mechanism 322, a first connecting frame 323, a second connecting frame 324, a first conveyor belt 325, and a second conveyor belt 326. The opening and closing mechanism 322 is disposed on the fixed frame 321. The first connecting frame 323 and the second connecting frame 324 are both slidably connected to the bottom of the fixed frame 321 along a second horizontal direction and are respectively in transmission connection with the opening and closing mechanism 322. The opening and closing mechanism 322 is configured to drive the first connecting frame 323 and the second connecting frame 324 to slide apart or toward the center along a second horizontal direction (e.g., the Y-axis direction in the figures), the second horizontal direction being perpendicular to the first horizontal direction. The first conveyor belt 325 is mounted on the first connecting frame 323 along the first horizontal direction, and the second conveyor belt 326 is mounted on the second connecting frame 324 along the first horizontal direction. A lifting space is formed between the first conveyor belt 325 and the second conveyor belt 326 for the turning portion 31 to pass through. The upper surface of the first conveyor belt 325 and the upper surface of the second conveyor belt 326 constitute the conveying surface of the conveying portion 32 .

[0137] The cooperation process of the conveying part 32 and the turning part 31 is as follows:

[0138] The opening and closing mechanism 322 drives the first connecting frame 323 and the second connecting frame 324 to slide apart to both sides, thereby forming a lifting space with a first width between the first conveyor belt 325 and the second conveyor belt 326, and the first width is greater than the width of the battery string.

[0139] Subsequently, the flipping unit 31 lifts the flipped battery string through the lifting space to above the first conveyor belt 325 and the second conveyor belt 326. Since the width of the lifting space is larger than the width of the battery string, the battery string can pass through the lifting space and reach above the first conveyor belt 325 and the second conveyor belt 326.

[0140] Next, the opening and closing mechanism 322 drives the first connecting frame 323 and the second connecting frame 324 to slide toward the middle, thereby forming a lifting space with a second width between the first conveyor belt 325 and the second conveyor belt 326, and the second width is smaller than the width of the battery string.

[0141] Finally, the turning unit 31 descends back to its original position through the lifting space. Since the width of the lifting space is smaller than the width of the battery string, the two sides of the battery string are blocked by the first conveyor belt 325 and the second conveyor belt 326 respectively, and then fall onto the first conveyor belt 325 and the second conveyor belt 326.

[0142] It can be seen that, during the process of transferring the battery string from the flipping portion 31 to the conveying portion 32 , there is no need to pick up the battery string, thereby preventing damage to the battery string.

[0143] As shown in FIG16 , the battery string gluing device in the embodiment of the present application optionally further includes a third regularizing plate 7, a fourth regularizing plate 8, a third regularizing drive assembly 9, and a fourth regularizing drive assembly 10, wherein the third regularizing plate 7 and the fourth regularizing plate 8 are relatively arranged on both sides of the conveying portion 32, and the length directions of the third regularizing plate 7 and the fourth regularizing plate 8 are parallel to the first horizontal direction. The third regularizing drive assembly 9 is mounted on the first connecting frame 323 and connected to the third regularizing plate 7, and the fourth regularizing drive assembly 10 is mounted on the second connecting frame 324 and is drive-connected to the fourth regularizing plate 8. After the conveying portion 32 conveys at least one battery cell in the carried battery string to the second conveyor line 4, the third regularizing drive assembly 9 and the fourth regularizing drive assembly 10 are configured to drive the third regularizing plate 7 and the fourth regularizing plate 4 to move relative to each other along the second horizontal direction to push the side edges of the battery string carried on the first conveyor belt 325 and the second conveyor belt 326, thereby completing the position correction of the battery string.

[0144] During the transition of the battery string from the conveying portion 32 to the second conveyor line 4, the battery cells therein may be misaligned. When at least one battery cell in the battery string reaches the second conveyor line 4, the third and fourth aligning plates 7 and 8, driven in conjunction with the third and fourth aligning drive assemblies 9 and 10, correct the position of the battery string, ensuring that the other battery cells in the battery string are aligned with the battery cells on the second conveyor line 4, thereby eliminating misalignment between the battery cells and ultimately ensuring the effectiveness of the second glue application mechanism on the second surface of the battery string.

[0145] Optionally, the second conveyor line 4 and the conveying part 32 convey the battery string in a step-by-step manner, conveying one battery cell at a time. After the first battery cell in the battery string is conveyed to the second conveyor line 4, the third regularizing plate 7 and the fourth regularizing plate 8 are driven in cooperation with the third regularizing drive component 9 and the fourth regularizing drive component 10 to correct the position of the battery string. Then the second conveyor line 4 adsorbs the first battery cell and adsorbs the remaining battery cells in the battery string when they are conveyed to the second conveyor line 4 to ensure the subsequent gluing accuracy.

[0146] Optionally, the third regularization plate 7 includes a plurality of elastic sheets spaced side by side, and the fourth regularization plate 8 is a rigid plate. After the fourth regularization drive assembly 10 drives the fourth regularization plate 8 to push the battery string, the third regularization drive assembly 9 drives the third regularization plate 7 to push the battery string.

[0147] When at least one battery cell in the battery string reaches the second conveyor line 4, the rigid fourth regularization plate 8 first pushes the battery string, and the elastic third regularization plate 7 then elastically presses against the battery string; after completing the regularization of the battery string, the elastic third regularization plate 7 first retreats, and the rigid fourth regularization plate 8 then retreats, thereby improving the regularization accuracy of the battery string.

[0148] As shown in Figures 11 to 13, the first connecting frame 323 is optionally provided with at least one first inclined guide groove 327, forming an angle greater than 0° and less than 90° with the second horizontal direction. The second connecting frame 324 is provided with at least one second inclined guide groove 328 corresponding one-to-one with the first inclined guide groove 327, and the second inclined guide groove 328 and the corresponding first inclined guide groove 327 are symmetrical about the central axis L of the lifting space.

[0149] Correspondingly, the opening and closing mechanism 322 includes a translation drive assembly 329, a first connecting rod 330, and a second connecting rod 331. The translation drive assembly 329 is mounted on the fixed frame 321. The first connecting rod 330 is fixedly connected to the movable component of the translation drive assembly 329. The first connecting rod 330 is provided with a first bearing 332 corresponding to each of the first inclined guide slots 327. The first bearing 332 is inserted into and slidably engages with the corresponding first inclined guide slot 327. The second connecting rod 331 is fixedly connected to the movable component of the translation drive assembly 329. The second connecting rod 331 is provided with a second bearing 333 corresponding to each of the second inclined guide slots 328. The second bearing 333 is inserted into and slidably engages with the corresponding second inclined guide slot 328.

[0150] The translation drive assembly 329 is configured to drive the first connecting rod 330 and the second connecting rod 331 to translate back and forth along the first horizontal direction, thereby driving the first connecting frame 323 and the second connecting frame 324 to slide apart toward both sides or slide toward the middle along the second horizontal direction.

[0151] By configuring the first connecting frame 323, the second connecting frame 324 and the opening and closing mechanism 322, the opening and closing mechanism 322 can drive the first connecting frame 323 and the second connecting frame 324 to slide apart toward both sides or slide toward the middle along the second horizontal direction, and ensure that the movement amount of the first connecting frame 323 and the second connecting frame 324 is consistent, ultimately ensuring that the two sides of the battery string fall onto the first conveyor belt 325 and the second conveyor belt 326 respectively.

[0152] As shown in Figure 13, optionally, the translation drive assembly 329 includes a driving member 334 and a driving plate 335, wherein the driving member 334 is installed on the fixed frame 321, the driving plate 335 is connected to the driving end of the driving member 334, the first connecting rod 330 and the second connecting rod 331 are fixedly connected to the two ends of the driving plate 335, and the driving member 334 drives the driving plate 335 to translate back and forth along the first horizontal direction, thereby driving the first connecting rod 330 and the second connecting rod 331 to translate synchronously along the first horizontal direction.

[0153] In addition, the opening and closing mechanism 322 further includes a first limiter 336 and a second limiter 337 provided on the fixing frame 321 and located on both sides of the driving plate 335 . The driving member 334 drives the driving plate 335 to translate back and forth between the first limiter 336 and the second limiter 337 .

[0154] The first and second stoppers 336 and 337 are provided to limit the travel of the first and second connecting rods 330 and 331. This ensures that, after the first and second connecting frames 323 and 324 slide apart and into position, a lifting space of a first width is formed between the first and second conveyor belts 325 and 326. After the first and second connecting frames 323 and 324 slide together toward the center and into position, a lifting space of a second width is formed between the first and second conveyor belts 325 and 326.

[0155] For example, in the embodiment shown in FIG13 , when the driving member 334 drives the driving plate 335 to translate toward the second limiting member 337, the driving plate 335 eventually abuts against the second limiting member 337, thereby forming a lifting space of the second width between the first conveyor belt 325 and the second conveyor belt 326. When the driving member 334 drives the driving plate 335 to translate toward the first limiting member 336, the driving plate 335 eventually abuts against the first limiting member 336, thereby forming a lifting space of the first width between the first conveyor belt 325 and the second conveyor belt 326.

[0156] Continuing with FIG. 13 , optionally, two first inclined guide slots 327 are provided on the first connecting bracket 323. A first bearing 332 is provided at each end of the first connecting rod 330, and the two first bearings 332 are connected in a one-to-one correspondence within the two first inclined guide slots 327. Two second inclined guide slots 328 are provided on the second connecting bracket 324. A second bearing 333 is provided at each end of the second connecting rod 331, and the two second bearings 333 are connected in a one-to-one correspondence within the two second inclined guide slots 328. This arrangement ensures stable sliding of the first connecting rod 330 and the second connecting rod 331, preventing the first connecting rod 330 and the second connecting rod 331 from becoming stuck or deflecting during sliding.

[0157] Optionally, the first gluing mechanism 2 and the second gluing mechanism 5 have the same structure. As shown in Figure 14, taking the second gluing mechanism 5 as an example, it includes a moving part 51, a screen mounting frame 52 and a scraper assembly 53, wherein: the screen mounting frame 52 is connected to the movable part of the moving part 51, and the printing screen is mounted on the screen mounting frame 52. The moving part 51 is configured to drive the printing screen to translate and rotate so that the printing screen is aligned with the battery string. The scraper assembly 53 is located above the printing screen and can rest against the printing screen. The scraper assembly 52 is configured to move close to the printing screen so that the glue on the printing screen passes through the printing screen downward and is accurately printed to the target position on the battery string, for example, to the position where the solder strip is located.

[0158] Of course, the first glue applying mechanism 2 and the second glue applying mechanism 5 can also be glue dispensing mechanisms, glue spraying mechanisms, etc., which implement glue application operations on the battery string by glue dispensing, glue spraying, etc.

[0159] Optionally, the second gluing mechanism 5 also includes a positioning camera 54, which is used to obtain the position information of the battery cell before the battery cell to be glued is transported to the bottom of the printing screen. The moving part 51 adjusts the position of the printing screen based on the above position information, and then implements the gluing operation on the second surface of the battery cell to ensure the gluing effect.

[0160] Continuing to refer to Figures 1 to 4, optionally, a first curing station and a first inspection station located after the first gluing station are further provided on the conveying path of the first conveyor line 1. Correspondingly, the battery string gluing device in the embodiment of the present application further includes a first curing mechanism 110 and a first inspection mechanism 120, wherein: the first curing mechanism 110 is provided at the first curing station and is located above the first conveyor line 1, and is configured to cure the glue applied on the first surface of the battery string. The first inspection mechanism 120 is provided at the first inspection station and is located above the first conveyor line 1, and is configured to detect the gluing quality of the first surface of the battery string.

[0161] Similarly, optionally, a second curing station and a second inspection station are further provided on the conveying path of the second conveyor line 4, which are located after the second gluing station. Correspondingly, the battery string gluing device in the embodiment of the present application further includes a second curing mechanism 130 and a second inspection mechanism 140, wherein: the second curing mechanism 130 is provided at the second curing station and located above the second conveyor line 4, and is configured to cure the glue applied on the second surface of the battery string. The second inspection mechanism 140 is provided at the second inspection station and located above the second conveyor line 4, and is configured to inspect the gluing quality of the second surface of the battery string.

[0162] Depending on the process requirements, the adhesive applied to the cell string surface can be UV adhesive, hot melt adhesive, or other adhesives. When using UV adhesive, the first curing mechanism 110 and the second curing mechanism 130 are UV light boxes capable of emitting UV light. The UV adhesive on the cell is cured after exposure to the UV light boxes. When using hot melt adhesive, the first curing mechanism 110 and the second curing mechanism 130 can be infrared heating light boxes or hot air heaters.

[0163] Optionally, the first inspection mechanism 120 and the second inspection mechanism 140 include CCD cameras, which analyze and inspect the quality of the glue application by acquiring appearance pictures of the battery cell after glue application.

[0164] Optionally, a blanking station located after the second gluing station is further provided on the conveying path of the second conveyor line 4. Correspondingly, the battery string gluing device in the embodiment of the present application also includes a blanking and conveying mechanism 150 and an EL detection camera 160. Among them, the blanking and conveying mechanism 150 is configured to pick up the battery string that has completed gluing from the blanking station, energize the picked battery string, and convey the battery string in the energized state to the EL detection station. The EL detection camera 160 is set at the EL detection station and is configured to perform EL detection on the battery string. The blanking and conveying mechanism 150 is also configured to convey the battery string that has passed the inspection to the subsequent station, for example, to the qualified string blanking conveyor line 170. The blanking and conveying mechanism 150 is also configured to store the battery string that has failed the inspection in the NG material box 180.

[0165] It can be seen that through the cooperation of the unloading and conveying mechanism 150 and the EL inspection camera 160, the classified unloading of the battery strings after the gluing is completed is realized, wherein the battery strings that pass the inspection are conveyed to the downstream work station, and the battery strings that fail the inspection are stored in the NG material box 180. In this way, it can be ensured that the battery strings flowing into the downstream work station are qualified battery strings.

[0166] EL testing, or electroluminescence testing, involves a material handling mechanism 150 energizing the battery string via the solder ribbons at both ends. An EL inspection camera 160 captures an infrared image of the energized battery string. By analyzing the infrared image of the battery string, defective cells can be detected within the string, and this information can be used to classify the string as either acceptable or unacceptable.

[0167] As shown in Figure 4, the unloading and handling mechanism 150 optionally includes a unloading drive unit 151 and an unloading arm 152 connected to the driving end of the unloading drive unit 151. The unloading arm 152 is provided with conductive clamps electrically connected to a power source at each end. The unloading drive unit 151 is used to drive the unloading arm 152 to move horizontally and vertically, thereby driving the unloading arm 152 to pick up the glue-applied battery string from the unloading station and implement the transfer of the battery string. The conductive clamps at each end of the unloading arm 152 respectively clamp the solder ribbons at both ends of the battery string to implement power supply to the battery string. The unloading arm 152 can, for example, be composed of a plurality of suction cups arranged side by side and spaced apart.

[0168] Optionally, the unloading drive unit 151 can also flip the unloading hand 152 so that the battery string adsorbed on the unloading hand 152 can face the EL detection camera 160, thereby ensuring the detection effect of the EL detection camera 160.

[0169] The present application also provides a battery string production device, which includes the battery string gluing device provided in any of the above embodiments. Specifically, the battery string production device provided in the present application can apply glue to the battery string after the battery cells are connected in series to form a battery string, thereby ensuring the connection strength between the battery cells and the soldering ribbon and improving the quality of the battery string.

[0170] Optionally, a laying station, a stringing station and a tool unloading station located in front of the first gluing station are sequentially provided on the conveying path of the first conveyor line 1. Correspondingly, as shown in Figures 1 and 2, the battery string production equipment in the embodiment of the present application also includes a laying device (not shown in the figure), a stringing device (not shown in the figure) and a tool unloading device 190, wherein: the laying device is arranged at the laying station, and is configured to lay the battery cells and welding ribbons on the first conveyor line 1 according to a predetermined stringing rule, and to press the welding ribbon pressing tool onto the battery cells. The stringing device is arranged at the stringing station, and is configured to weld the laid battery cells and welding ribbons conveyed to the stringing station into a battery string. The tool unloading device 190 is configured to move the welding ribbon pressing tool conveyed to the tool unloading station away from the battery string.

[0171] Optionally, the battery string production equipment also includes a tooling return conveyor line 210, and the tooling unloading device 190 places the tooling moved from the tooling unloading station on the tooling return conveyor line 210, and the tooling return conveyor line 210 returns the tooling to the side of the laying station for next use.

[0172] As can be seen, through the coordination of the placement device, the stringing device, the tooling unloading device 190, and the first conveyor line 1, the battery string production equipment of the embodiment of the present application realizes the stringing of battery cells. In particular, after the battery cells are stringed together on the first conveyor line 1, the first surface glue coating is completed on the first conveyor line 1, thereby improving processing efficiency and reducing equipment size.

[0173] Optionally, the battery string production equipment in the embodiment of the present application further includes a string cutting device 200 disposed after the first gluing station. The string cutting device 200 is configured to separate the battery strings that have completed the first surface gluing. The first conveyor line 1 conveys the separated battery strings to the handling station. When the first conveyor line 1 is composed of a first conveyor section 11 and a second conveyor section 12, the string cutting device 200 can be disposed in the gap between the first conveyor section 11 and the second conveyor section 12.

[0174] The present application has been described above in sufficient detail with certain specificity. Those skilled in the art will understand that the descriptions in the examples are merely illustrative, and that all modifications made without departing from the true spirit and scope of the present application are intended to be within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the description in the examples.
