As Figure 1 shown, a conventional battery string feeding device includes a string connection part 1, a string cutting knife 2, a first conveyor line 3, a battery string handling mechanism 104, a second conveyor line 105, and a feeding conveyor line 106. Among them, the first conveyor line 3 is located behind the string connection part 1, the string cutting knife 2 is arranged between the output end of the string connection part 1 and the first conveyor line 3, the second conveyor line 105 is arranged side by side with the first conveyor line 3, and the output end of the second conveyor line 105 is docked with the input end of the feeding conveyor line 106.

[0003] After the battery wafers with the front side facing up and the solder tapes are welded into strings on the string connection part 1, they are cut into battery strings of a predetermined length by the string cutting knife 2 and then flow onto the first conveyor line 3. The battery string handling mechanism 104 picks up the battery string from the first conveyor line 3, flips the battery string by 180°, so that the back side of the battery string faces up, and then transports the battery string to the second conveyor line 105. The second conveyor line 105 transports the battery string to the feeding conveyor line 106, and the typesetting picking mechanism picks up the battery string from the feeding conveyor line 106 and performs typesetting.

[0004] The overall length of the conventional battery string feeding device is relatively long, occupying a large space. Summary of the Utility Model

[0005] In order to solve the above technical problems, the present application provides a battery string feeding device and a typesetting device, which adopt the following technical solutions:

[0006] A battery string feeding device includes a string connection part, a string cutting knife, a first conveyor line, a first handling mechanism, a second handling mechanism, and a feeding transition part, wherein:

[0007] The first conveyor line is located behind the string connection part, the string cutting knife is located between the string connection part and the first conveyor line. After the battery wafers with the front side facing up are welded into strings on the string connection part with solder tapes, they are cut into battery strings of a predetermined length by the string cutting knife and flow onto the first conveyor line;

[0008] The first conveyor line is configured to convey the battery string along a first horizontal direction;

[0009] The feeding transition part is arranged above the first conveyor line, and the first handling mechanism is arranged between the first conveyor line and the feeding transition part;

[0010] The first handling mechanism is configured to pick up the battery string from the first conveyor line and turn the picked-up battery string over so that its back side faces up; alternatively, the battery string feeding device further includes a gluing mechanism, the first handling mechanism is configured to transport the picked-up battery string to the gluing mechanism, the gluing mechanism is configured to apply glue to the front side of the battery string, and after turning the battery string with the front side glued over so that its back side faces up, apply glue to the back side of the battery string;

[0011] The second handling mechanism is configured to pick up the battery string with its back side facing up from the first handling mechanism or from the gluing mechanism and transport the battery string to the loading transition part.

[0012] In the battery string feeding device of the present application, the loading transition part and the first conveyor line are arranged in a layered and vertical manner. After the battery string cut by the string cutter flows into the first conveyor line, the first conveyor line transports it to the lower part of the loading transition part; subsequently, the first handling mechanism turns the battery string over so that its back side faces up, or transports the battery string to the gluing mechanism, and the gluing mechanism completes the turning of the battery string during the gluing process so that the back side of the battery string faces up; subsequently, the second handling mechanism transports the battery string with its back side facing up on the first handling mechanism or the gluing mechanism to the loading transition part. During typesetting, the typesetting picking mechanism can pick up the battery string from the loading transition part and perform typesetting on the battery string.

[0013] Since the loading transition part and the first conveyor line are arranged in a layered and vertical manner, compared with the traditional battery string feeding device, the length and occupied space of the battery string feeding device of the present application are greatly reduced. In addition, when including a gluing mechanism, the battery string feeding device of the present application can also be compatible with the typesetting and feeding of 0BB (no main grid) battery strings that need to be glued.

[0014] In some embodiments, the first handling mechanism includes a first translation driving part, a first lifting driving part, a first flipping driving part and a first adsorption part, wherein: the first lifting driving part is connected to the moving part of the first translation driving part, the first flipping driving part is connected to the moving part of the first lifting driving part, and the first adsorption part is connected to the moving part of the first flipping driving part; the first translation driving part is used to drive the first adsorption part to translate along the second horizontal direction, the first lifting driving part is used to drive the first adsorption part to lift, the first flipping driving part is used to drive the first adsorption part to flip, and the first adsorption part is used to adsorb the battery string, and the second horizontal direction is perpendicular to the first horizontal direction.

[0015] For the battery string that does not require sizing, through the coordinated driving of the first translation driving part, the first lifting driving part and the first flipping driving part, the first adsorption part can pick up the battery string from the first conveyor line, and flip the picked-up battery string to face upwards on the back, and finally be transported to the loading transition part by the second handling mechanism. For the main-gridless battery string that requires sizing, through the coordinated driving of the first translation driving part and the first lifting driving part, the first adsorption part can pick up the battery string from the first conveyor line, and transport the picked-up battery string to the sizing mechanism. The sizing mechanism flips the battery string during the sizing process, making the back of the battery string face upwards, and finally be transported to the loading transition part by the second handling mechanism.

[0016] In some embodiments, the second handling mechanism includes a second lifting driving part, a rotation driving part, a rotating shaft, a second adsorption part and two swing arms, wherein: the rotation driving part is connected to the movable part of the second lifting driving part, the rotating shaft is connected to the movable part of the rotation driving part and extends along the first horizontal direction; the upper ends of the two swing arms are fixedly connected to the rotating shaft, the second adsorption part is arranged between the two swing arms along the first horizontal direction, and the lower ends of the two swing arms are respectively rotatably connected to both ends of the second adsorption part; the rotation driving part is configured to drive the two swing arms to swing through the rotating shaft, so as to drive the second adsorption part to move between the first handling mechanism and the loading transition part; or the rotation driving part is configured to drive the two swing arms to swing through the rotating shaft, so as to drive the second adsorption part to move between the loading transition part and the sizing mechanism; the second lifting driving part is configured to drive the second adsorption part to lift and lower.

[0017] Under the coordinated driving of the second lifting driving part and the rotation driving part, the second adsorption part connected to the lower end of the swing arm moves, switches and lifts and lowers between the first handling mechanism and the loading transition part, so as to suck the flipped battery string from the first handling mechanism and transport the sucked battery string to the loading transition part, or moves, switches and lifts and lowers between the loading transition part and the sizing mechanism, so as to suck the sized and flipped battery string from the sizing mechanism and transport the sucked battery string to the loading transition part. Compared with the conventional translational handling mechanism, the second handling mechanism that implements handling in a swinging manner has the advantages of simple structure and small occupied space.

[0018] In some embodiments, the second handling mechanism further includes a horizontal limiting component, and the horizontal limiting component includes a fixed frame, a connecting piece and a connecting rod, wherein: the fixed frame is arranged on the movable part of the second lifting driving part, and the upper end of the connecting piece is hinged to the fixed frame; the first end of the connecting rod is hinged to the lower end of the connecting piece, and the second end of the connecting rod is fixedly connected to the end of the second adsorption part; the distance between the upper hinge point of the connecting piece and the central axis of the rotating shaft in the second horizontal direction is equal to the distance between the lower hinge point of the connecting piece and the rotation center of the second adsorption part in the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0019] Since both ends of the second adsorption part are rotatably connected to the lower ends of the two swing arms, during the process of the rotation driving part driving the two swing arms to swing, the horizontal limiting component realizes the horizontal limitation of the second adsorption part, so that the second adsorption part always maintains a horizontal state during the swinging process. Thereby, it is ensured that after the second adsorption part moves in place, it can stably suck the battery string on the first handling mechanism or the glue application mechanism in a horizontal state, and place the sucked battery string on the feeding transition part smoothly in a horizontal state.

[0020] In some embodiments, the connecting piece is a cylinder. The cylinder block of the cylinder is hinged to the fixed frame, and the telescopic rod of the cylinder is hinged to the first end of the connecting rod; after the second adsorption part moves in place, the cylinder is configured to drive the second adsorption part to flip relative to the lower end of the swing arm.

[0021] Using a cylinder as the connecting piece, during the swinging process of the second adsorption part, the extending length of the telescopic rod of the cylinder is ensured to remain unchanged, so as to ensure that the second adsorption part always maintains a horizontal state during the swinging process. When the second adsorption part swings to a predetermined position, for example, when it swings to a predetermined manual inspection station, the cylinder can control the telescopic rod to extend and retract, so as to drive the second adsorption part to flip outwards from the horizontal state to the vertical state, so as to facilitate the inspection of the battery string adsorbed on the second adsorption part.

[0022] In some embodiments, the feeding transition part is a conveyor belt for conveying the battery string along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the width of the conveying surface of the feeding transition part along the first horizontal direction is at least equal to the length of one string of battery strings, and at least two strings of battery strings can be carried on the conveying surface of the feeding transition part along the second horizontal direction; alternatively, the feeding transition part is a carrying platform for carrying one string of battery strings.

[0023] Using a conveyor belt as the feeding transition part, the feeding transition part can carry at least two strings of battery strings along the second horizontal direction, thereby realizing the buffering of the battery strings, ensuring that the subsequent typesetting picking mechanism can obtain the battery strings from the feeding transition part in time, and preventing the occurrence of feeding waiting. Using a carrying platform as the feeding transition part reduces the installation space occupied by the feeding transition part. In this way, a storage box can be arranged on the side of the feeding transition part, and the storage box will not interfere with the handling of the second handling part.

[0024] In some embodiments, the battery string feeding device further includes a detection mechanism arranged on the moving path of the second handling mechanism; the second handling mechanism is further configured to carry the battery string with the back facing up picked up to the detection mechanism, and the detection mechanism is configured to perform quality inspection on the battery string, and the second handling mechanism carries the battery string with qualified inspection to the feeding transition part.

[0025] By setting up a detection mechanism, the second handling mechanism can transport the battery string picked up with the back facing up to the detection mechanism, and the detection mechanism performs quality inspection on the battery string. The second handling mechanism only transports the battery strings that pass the inspection to the loading transition section, preventing the battery strings with quality defects from flowing into the subsequent layout station.

[0026] In some embodiments, the detection mechanism includes an EL detection camera, and an energizing component is arranged on the second handling mechanism. The energizing component is configured to energize the battery string on the second handling mechanism; the EL detection camera is configured to acquire an infrared image of the energized battery string to perform quality inspection on the battery string.

[0027] Through the cooperation of the EL detection camera and the energizing component, the quality inspection of the battery string is realized, so as to ensure that only the battery strings that pass the inspection enter the subsequent layout station. In addition, the energizing component is arranged on the second handling mechanism, and the EL detection camera is arranged at the detection station. Therefore, the second handling mechanism can complete the inspection of the battery string during the process of transporting the battery string, without having to transfer the battery string to a dedicated inspection table, thus improving the inspection efficiency and avoiding the additional grasping and placing of the battery string, which is beneficial to reducing the fragmentation rate of the battery chips.

[0028] In some embodiments, the energizing component includes a first clamping member and a second clamping member, where: the first clamping member is arranged at the first end of the second handling mechanism, the first clamping member is electrically connected to the positive electrode of the power supply, and the first clamping member is configured to clamp the extended welding tape at the first end of the battery string; the second clamping member is arranged at the second end of the second handling mechanism, the second clamping member is electrically connected to the negative electrode of the power supply, and the second clamping member is configured to clamp the extended welding tape at the second end of the battery string.

[0029] An energizing component with a simple structure is provided. After the second handling mechanism picks up the battery string, the first clamping member and the second clamping member respectively clamp the extended welding tapes at both ends of the battery string, and the power supply can energize the battery string through the first clamping member and the second clamping member.

[0030] In some embodiments, the battery string feeding device further includes a telescopic driving mechanism; the telescopic driving mechanism is arranged below the loading transition section. The telescopic driving mechanism is used to carry the NG material box and drive the NG material box to translate along the second horizontal direction to drive the NG material box to switch between the receiving position outside the loading transition section and the avoiding position below the loading transition section, where the second horizontal direction is perpendicular to the first horizontal direction; alternatively, the battery string feeding device further includes at least one storage box fixedly arranged on the side of the loading transition section.

[0031] When the installation space occupied by the loading transition part is large, for example, when the loading transition part adopts a conveyor belt capable of caching battery strings, placing the NG material box beside the loading transition part will inevitably interfere with the handling of the second handling mechanism. By arranging the telescopic driving mechanism below the loading transition part, the telescopic driving mechanism drives the NG material box to switch between the material receiving position outside the loading transition part and the avoidance position below the loading transition part. It not only realizes the recycling and caching of unqualified battery strings, but also does not hinder the normal handling of the second handling mechanism. When the installation space occupied by the loading transition part is small, for example, when the loading transition part adopts a carrying platform that only carries one string of battery strings, there is enough installation space beside the loading transition part. Therefore, by setting a storage box beside the loading transition part, the recycling and caching of unqualified battery strings can be implemented.

[0032] In some embodiments, the gluing mechanism includes a first gluing conveyor line, a first gluing part, a flipping conveyor part, a second gluing conveyor line and a second gluing part, where: the first gluing conveyor line is configured to receive the battery strings carried by the first handling mechanism and convey the battery strings to the first gluing station and the transfer station in sequence along the first horizontal direction; the first gluing part is arranged at the first gluing station and above the first gluing conveyor line, and the first gluing part is configured to glue the front surface of the battery strings; the flipping conveyor part is arranged at the transfer station, and the flipping conveyor part is configured to pick up the battery strings that have completed front surface gluing at the transfer station, and after flipping the battery strings so that the back surface faces up, convey the battery strings to the second gluing conveyor line; the second gluing conveyor line is configured to convey the battery strings to the second gluing station and the unloading station in sequence along the first horizontal direction, the second gluing part is arranged at the second gluing station and above the second gluing conveyor line, and the second gluing part is configured to glue the back surface of the battery strings; the second handling mechanism picks up the battery strings with the back surface facing up that have completed gluing from the unloading station.

[0033] After the front surface of the battery strings is glued on the first gluing conveyor line, the flipping conveyor part flips the battery strings and conveys the flipped battery strings to the second gluing conveyor line. The second gluing conveyor line conveys the flipped battery strings to the second gluing station for back surface gluing; the second gluing conveyor line is used to carry and convey the battery strings to implement back surface gluing. That is, through the cooperation of the first gluing conveyor line, the first gluing part, the flipping conveyor part, the second gluing conveyor line and the second gluing part, the gluing mechanism realizes continuous gluing of the two surfaces of the battery strings, and realizes the flipping of the battery strings during the gluing process, so that the back surface of the battery strings faces up.

[0034] In some embodiments, the flipping and conveying unit includes a flipping unit and a conveying unit, where: both the conveying unit and the second sizing and conveying line are located above the first sizing and conveying line, and the conveying directions of the conveying unit and the second sizing and conveying line are opposite to the conveying direction of the first sizing and conveying line. The output end of the conveying unit is docked with the input end of the second sizing and conveying line; the flipping unit is configured to pick up the battery string that has completed front-side sizing at the transfer station, and flip the battery string so that its back side faces up. The flipping unit is also configured to transport the flipped battery string to the conveying surface of the conveying unit; the conveying unit is configured to convey the battery string to the second sizing and conveying line.

[0035] After the flipping unit finishes flipping the battery string, it places the battery string on the conveying surface of the conveying unit. The conveying unit directly conveys the battery string to the second sizing and conveying line. There is no need to perform secondary picking of the battery string after flipping, thus reducing the risk of damage to the battery string.

[0036] In some embodiments, the flipping unit includes a lifting drive unit, a lifting frame, a flipping frame, a flipping drive unit, and a suction component, where: the lifting frame is connected to the movable part of the lifting drive unit, the flipping frame is rotatably connected to the lifting frame, the flipping frame is in transmission connection with the flipping drive unit provided on the lifting frame, and the suction component is installed on the flipping frame; the lifting drive unit is configured to drive the suction component to descend so that the suction component adsorbs the battery string from the transfer station; the flipping drive unit is configured to drive the suction component to flip, so as to drive the battery string adsorbed on the suction component to flip, making the back side of the battery string face up; the lifting drive unit is also configured to drive the suction component to ascend to place the flipped battery string on the conveying surface of the conveying unit.

[0037] By arranging the flipping unit, the flipping unit can adsorb the battery string from the transfer station, flip the battery string so that its back side faces up, and then place the battery string on the conveying surface of the conveying unit.

[0038] In some embodiments, the conveying part includes a fixed frame, an opening and closing unit, a first connecting frame, a second connecting frame, a first conveyor belt and a second conveyor belt, wherein: the opening and closing unit 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 connected to the opening and closing unit in a transmission manner, and the opening and closing unit 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, wherein 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 A lifting space for the flipping part to pass through is formed between the first conveyor belt and the second conveyor belt; when the opening and closing unit drives the first connecting frame and the second connecting frame to slide apart on 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 flipping part drives the flipped battery string to pass upward through the lifting space; when the opening and closing unit drives the first connecting frame and the second connecting frame to slide together toward the middle, a lifting space with a second width is formed between the first conveyor belt and the second conveyor belt, and the second width is less than the width of the battery string, and the flipping part descends through the lifting space, so that the battery string falls onto the first conveyor belt and the second conveyor belt.

[0039] The conveying part is configured so that the flipping part can lift the flipped battery string above the conveying surface of the conveying part, and when the flipping part is lowered back to its original position, the battery string on the flipping part automatically falls onto the conveying surface of the conveying part. In other words, when the battery string is switched from the flipping part to the conveying part, there is no need to pick up the battery string a second time, thereby preventing damage to the battery string.

[0040] The present application also provides a typesetting device, which includes two battery string feeding devices and typesetting picking mechanisms as described in any of the above items, wherein: the two battery string feeding devices are arranged side by side and spaced apart in a mirror image along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the typesetting picking mechanism is arranged above the two feeding transition parts and between the two second conveying mechanisms, and the typesetting picking mechanism includes a first picking part and a second picking part, the first picking part is used to pick up the battery string from one of the feeding transition parts and typesetting, and the second picking part is used to pick up the battery string from the other feeding transition part and typesetting.

[0041] The two battery string feeding devices are arranged side by side and spaced apart in a mirror image along the second horizontal direction, so that the feeding transition parts of the two battery string feeding devices can synchronously supply the battery string. The layout picking mechanism synchronously picks up the battery string from the feeding transition parts of the two battery string feeding devices through the first picking part and the second picking part, and performs layout, thereby improving the layout efficiency.

[0042] In some embodiments, the typesetting picking mechanism further includes a second translation driving part, a distance separating driving part, a third lifting driving part, and a fourth lifting driving part, wherein: the distance separating driving part is connected to the moving part of the second translation driving part, the third lifting driving part and the fourth lifting driving part are connected to the moving part of the distance separating driving part, the first picking part is connected to the moving part of the third lifting driving part, and the second picking part is connected to the moving part of the fourth lifting driving part; the second translation driving part is configured to drive the first picking part and the second picking part to synchronously translate along a first horizontal direction; the third lifting driving part is configured to drive the first picking part to lift, and the fourth lifting driving part is configured to drive the second picking part to lift; the distance separating driving part is configured to drive the first picking part and the second picking part to translate in opposite directions along a second horizontal direction when the first picking part and the second picking part are at different heights, so that the first picking part and the second picking part move closer to the middle or move apart from each other; wherein, the second horizontal direction is perpendicular to the first horizontal direction; the first picking part and the second picking part are further respectively configured to be able to drive the picked battery strings to rotate along the horizontal direction.

[0043] It can be seen that by setting the typesetting picking mechanism, the typesetting picking mechanism realizes the synchronous picking of two battery strings on two feeding transition parts and the typesetting of the two picked battery strings, thereby improving the typesetting efficiency. In addition, since the first picking part and the second picking part of the typesetting picking mechanism can move closer to the middle and produce partial intersection, when the distance between the two second handling mechanisms is set to be small, it can also ensure that the first picking part and the second picking part of the typesetting picking mechanism can smoothly pass between the two second handling mechanisms, thereby reducing the size of the battery string feeding device in the embodiments of the present application and saving the installation space.

[0044] In some embodiments, the distance separating driving part includes a synchronous belt driving component and a synchronous belt, wherein: the synchronous belt driving component is arranged on the moving part of the second translation driving part, the synchronous belt is installed on the synchronous belt driving component along the second horizontal direction, the fixed part of the third lifting driving part is fixedly connected to the first side belt body of the synchronous belt, and the fixed part of the fourth lifting driving part is fixedly connected to the second side belt body of the synchronous belt; the synchronous belt driving component is configured to drive the synchronous belt to rotate to drive the first picking part and the second picking part to move closer to the middle or move apart from each other.

[0045] A distance separating driving part with a simple structure and stable driving is provided, which drives the synchronous belt to rotate through the synchronous belt driving component to drive the first picking part and the second picking part respectively connected to the first side belt body and the second side belt body of the synchronous belt to move closer to the middle or move apart from each other.

[0046] In some embodiments, the typesetting device further includes a regular conveying mechanism, a welding picking mechanism, and a welding mechanism, where: the typesetting picking mechanism is configured to place two battery strings picked from the output end of the feeding transition part onto the regular conveying mechanism respectively according to the requirements of the typesetting positive and negative polarities; the regular conveying mechanism is configured to receive and regularize the battery strings placed by the typesetting picking mechanism; the welding picking mechanism includes string picking components arranged in one-to-one correspondence with each battery string in the battery string array; the regular conveying mechanism is further configured to convey the regularized battery strings to the string picking station according to the requirements of the typesetting position, and the welding picking mechanism moves to drive the string picking component corresponding to the battery string at the string picking station to move to the string picking station to pick up the battery string; the welding picking mechanism moves to drive the string picking component picking up the battery string to the welding station, and the welding mechanism welds the bus bar to the extended welding strip at the end of the battery string located at the welding station; the welding picking mechanism is further configured to, after the bus bars of the battery strings picked up by each string picking component are all welded, move to lay the battery strings picked up by each string picking component on the glass plate.

[0047] After the typesetting picking mechanism places two battery strings picked from the feeding transition part onto the regular conveying mechanism respectively according to the requirements of the typesetting positive and negative polarities, the regular conveying mechanism then regularizes the battery strings according to the requirements of the typesetting position and conveys the regularized battery strings to the string picking station. After the welding picking mechanism picks up the battery strings from the string picking station, it conveys the battery strings to the welding station, and the welding mechanism directly welds the bus bar to the battery strings on the welding picking mechanism. After all the bus bars are welded, the welding picking mechanism then lays all the battery strings on the glass plate. Thus, the typesetting and bus bar welding of a battery string array are completed.

[0048] It can be seen that the typesetting device of the present application realizes the automatic feeding, automatic typesetting, and automatic welding of the bus bar for the battery strings in sequence, without manual interference throughout the process, thereby greatly improving the typesetting efficiency.

[0087] After the solar cells and the welding tapes are welded into a string on the series connection part 1, they are cut into battery strings by the string cutter 2 and flow into the first conveyor line 3.

[0088] The first conveyor line 3 conveys the battery strings to the lower part of the loading transition part 6.

[0089] Subsequently, the first handling mechanism 4 picks up the battery strings from the first conveyor line 3 and flips the battery strings so that their backs face up.

[0090] Then, the second handling mechanism 5 picks up the battery strings with their backs facing up from the first handling mechanism 4 and transports the battery strings to the loading transition part 6.

[0091] In this way, during typesetting, the typesetting picking mechanism can pick up the battery strings with their backs facing up from the loading transition part 6 and perform typesetting on the battery strings.

[0092] Since the loading transition part 6 and the first conveyor line 3 are arranged in a layered manner, up and down, compared with the traditional battery string feeding device, the length and occupied space of the battery string feeding device in the embodiment of the present application are greatly reduced.

[0093] As is known to those skilled in the art, after the 0BB (no main grid) solar cells are welded into a string, the connection firmness between the welding tapes and the solar cells is relatively low. Therefore, before typesetting, it is necessary to apply glue to the front and back of the battery strings to further glue the welding tapes to the solar cells and improve the connection firmness between the welding tapes and the solar cells.

[0094] In order to be compatible with the typesetting and feeding of 0BB (no main grid) battery strings that need to be glued, as Figures 2 to 3 shown, optionally, the battery string feeding device in the embodiment of the present application further includes a gluing mechanism 7.

[0095] When feeding the 0BB battery strings needs to be implemented, after the first handling mechanism 4 picks up the battery strings from the first conveyor line 3, it does not flip the battery strings, but directly transports the battery strings in the state of facing up to the gluing mechanism 7.

[0096] The gluing mechanism 7 completes the front gluing of the battery strings, and after flipping the battery strings with the front glued to face their backs up, glues the backs of the battery strings.

[0097] Subsequently, the second handling mechanism 5 picks up the battery strings that have been glued and have their backs facing up from the gluing mechanism 7 and transports the battery strings to the loading transition part 6. In this way, during typesetting, the typesetting picking mechanism can pick up the battery strings that have been glued and have their backs facing up from the loading transition part 6 and perform typesetting on the battery strings.

[0098] It can be seen that by setting the sizing mechanism 7, on the one hand, continuous sizing of the two surfaces of the battery string is achieved, enabling the battery string feeding device of the present application to be compatible with the typesetting and feeding of main-gridless battery strings that require sizing. On the other hand, flipping of the battery string is achieved, such that the battery string is placed on the loading transition part 6 with its back facing up, meeting the typesetting requirements.

[0099] Optionally, the first handling mechanism 4 includes a first translation driving part, a first lifting driving part, a first flipping driving part, and a first adsorption part, where: the first lifting driving part is connected to the moving part of the first translation driving part, the first flipping driving part is connected to the moving part of the first lifting driving part, and the first adsorption part is connected to the moving part of the first flipping driving part. The first translation driving part is used to drive the first adsorption part to translate along the second horizontal direction (such as the Y-axis direction), the first lifting driving part is used to drive the first adsorption part to lift, the first flipping driving part is used to drive the first adsorption part to flip, and the first adsorption part is used to adsorb the battery string. The second horizontal direction is perpendicular to the first horizontal direction.

[0100] For battery strings that do not require sizing, through the coordinated driving of the first translation driving part, the first lifting driving part, and the first flipping driving part, the first adsorption part can pick up the battery string from the first conveyor line 3, and flip the picked-up battery string so that its back faces up. The battery string with its back facing up is finally transported to the loading transition part 6 by the second handling mechanism 5.

[0101] For main-gridless battery strings that require sizing, after the first adsorption part picks up the battery string from the first conveyor line 3 through the coordinated driving of the first translation driving part and the first lifting driving part, it transports the picked-up battery string to the sizing mechanism 7. During the sizing process, the sizing mechanism 7 flips the battery string so that its back faces up. The battery string with its back facing up after sizing is finally transported to the loading transition part 6 by the second handling mechanism 5.

[0102] Both the first translation driving part and the first lifting driving part can adopt various existing linear driving modules or robots that can drive the first adsorption part to translate and lift, such as cylinder driving modules or screw motor driving modules, etc.

[0103] The first flipping driving part can adopt various existing flipping driving modules that can drive the first adsorption part to flip, such as a flipping driving module composed of a rotary driving motor, a rotating shaft, and a flipping plate.

[0104] Optionally, the first adsorption part includes a mounting bracket and several suction cups arranged on the mounting bracket along the first horizontal direction. The several suction cups cooperate to suck the battery string from the first conveyor line 3.

[0105] Such as Figures 5 to 7As shown, optionally, the second handling mechanism 5 includes a second lifting drive unit 51, a rotation drive unit 52, a rotating shaft 53, a second adsorption unit 54, and two swing arms 55, where: The rotation drive unit 52 is connected to the movable part of the second lifting drive unit 51, the rotating shaft 53 is connected to the movable part of the rotation drive unit 52, and extends along the first horizontal direction. The upper ends of the two swing arms 55 are fixedly connected to the rotating shaft 53, the second adsorption unit 54 is arranged between the two swing arms 55 along the first horizontal direction, and the lower ends of the two swing arms 55 are respectively rotatably connected to both ends of the second adsorption unit 54.

[0106] The rotation drive unit 51 is configured to drive the two swing arms 55 to swing via the rotating shaft 53, so as to drive the second adsorption unit 54 to move between the first handling mechanism 4 and the feeding transition part 6. Or the rotation drive unit 51 is configured to drive the two swing arms 55 to swing via the rotating shaft 53, so as to drive the second adsorption unit 54 to move between the feeding transition part 6 and the sizing mechanism 7. The second lifting drive unit 51 is configured to drive the second adsorption unit 54 to lift and lower.

[0107] For the battery string that does not require sizing, the second handling mechanism 5 needs to suck the battery string that has been flipped from the first handling mechanism 4, and then transport the sucked battery string to the feeding transition part 6. The specific process is as follows:

[0108] First, the rotation drive unit 52 drives the two swing arms 55 to swing via the rotating shaft 53, so that the second adsorption unit 54 moves above the first handling mechanism 4.

[0109] Subsequently, the second lifting drive unit 51 drives the second adsorption unit 54 to descend towards the first handling mechanism 4, so that the second adsorption unit 54 approaches and adsorbs the battery string with the back facing up that has been flipped on the first handling mechanism 4.

[0110] Then, the second lifting drive unit 51 drives the second adsorption unit 54 to rise and return to its original position, and the rotation drive unit 52 drives the two swing arms 55 to swing via the rotating shaft 53, so that the second adsorption unit 54 moves above the feeding transition part 6.

[0111] Finally, the second lifting drive unit 51 drives the second adsorption unit 54 to descend towards the feeding transition part 6, and the second adsorption unit 54 releases the battery string to the feeding transition part 6.

[0112] For the main-gridless battery string that requires sizing, the second handling mechanism 5 needs to suck the battery string that has been flipped from the sizing mechanism 7, and then transport the sucked battery string to the feeding transition part 6. The specific process is as follows:

[0113] First, the rotation drive unit 52 drives the two swing arms 55 to swing via the rotating shaft 53, so that the second adsorption unit 54 moves above the sizing mechanism 7.

[0114] Subsequently, the second lifting drive unit 51 drives the second adsorption unit 54 to descend towards the sizing mechanism 7, so that the second adsorption unit 54 approaches and adsorbs the battery string that has been sized and flipped on the sizing mechanism 7.

[0115] Next, the second lifting drive unit 51 drives the second adsorption unit 54 to rise and return to its original position. The rotation drive unit 52 drives the two swing arms 55 to swing via the rotating shaft 53, so that the second adsorption unit 54 moves above the loading transition section 6.

[0116] Finally, the second lifting drive unit 51 drives the second adsorption unit 54 to descend towards the loading transition section 6, and the second adsorption unit 54 releases the battery string onto the loading transition section 6.

[0117] To improve the lifting stability of the second adsorption unit 54, optionally, as Figure 6 shown, the second lifting drive unit 51 includes two lifting drive modules arranged at intervals along the first horizontal direction. The rotation drive unit 52 is arranged on the moving part of one of the lifting drive modules. The first end of the rotating shaft 53 is in transmission connection with the moving part of the rotation drive unit 52, and the second end of the rotating shaft 53 is rotatably connected to the moving part of the other lifting drive module. The rotation drive unit 52 can adopt various existing rotation drive modules capable of driving the rotating shaft 53 to rotate, such as a rotation motor.

[0118] Optionally, the second adsorption unit 54 includes a mounting cross beam 541 and a plurality of suction cup groups 542. Among them, both ends of the mounting cross beam 541 are rotatably connected to the lower ends of one of the swing arms 55, and the plurality of suction cup groups 542 are arranged at intervals along the length direction of the mounting cross beam 541 (i.e., the first horizontal direction) on the mounting cross beam 541.

[0119] As Figures 6 to 7 shown, optionally, the second handling mechanism 5 further includes a horizontal limiting component 56. The horizontal limiting component 56 includes a fixing frame 561, a connecting piece 562, and a connecting rod 563, where: the fixing frame 561 is arranged on the moving part of the second lifting drive unit 51, the upper end of the connecting piece 562 is hinged to the fixing frame 561, the lower end of the connecting piece 562 is hinged to the first end of the connecting rod 563, and the second end of the connecting rod 563 is fixedly connected to the end of the second adsorption unit 54. As Figure 7 shown, the distance between the hinge point of the upper end of the connecting piece 562 and the central axis of the rotating shaft 53 in the second horizontal direction is a, and the distance between the hinge point of the lower end of the connecting piece 562 and the rotation center of the second adsorption unit 54 in the second horizontal direction is b, where a = b.

[0120] Since both ends of the second adsorption part 54 are rotatably connected to the lower ends of the two swing arms 55, during the process of the rotation driving part 52 driving the two swing arms 55 to swing, the horizontal limit assembly 56 realizes the horizontal limit of the second adsorption part 54, so that the second adsorption part 54 always maintains a horizontal state during the swinging process.

[0121] In this way, it can be ensured that after the second adsorption part 54 moves in place, it can stably suck the battery string on the first handling mechanism 4 or the glue application mechanism 7 in a horizontal state, and ensure that the second adsorption part 54 smoothly places the sucked battery string on the feeding transition part 6 in a horizontal state.

[0122] Optionally, the connecting piece 562 is a cylinder. As Figure 7 shown, the cylinder block of the cylinder is hinged on the fixed frame 561, and the telescopic rod of the cylinder is hinged to the first end of the connecting rod 563. Using the cylinder as the connecting piece 562, during the swinging process of the second adsorption part 54, the extending length of the telescopic rod of the cylinder remains unchanged, so as to ensure that the second adsorption part 54 always maintains a horizontal state during the swinging process.

[0123] When the second adsorption part 54 swings to a predetermined position, for example, swings to a predetermined manual inspection station, the cylinder can control the telescopic rod to expand and contract, so as to drive the second adsorption part 54 to turn outwards from the horizontal state to the vertical state, so as to facilitate the inspection of the battery string adsorbed on the second adsorption part 54.

[0124] Of course, if the flipping drive of the second adsorption part 54 does not need to be implemented, an ordinary connecting rod can also be used as the connecting piece 562.

[0125] As Figure 4 shown, in an alternative embodiment, a conveyor belt is used as the feeding transition part 6. The conveyor belt is used to convey the battery string along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction. The width of the conveying surface of the feeding transition part 6 along the first horizontal direction (such as the X-axis direction) is at least equal to the length of a string of battery strings, and at least two strings of battery strings can be carried on the conveying surface of the feeding transition part 6 along the second horizontal direction (such as the Y-axis direction). When the second handling mechanism 5 conveys the battery string to the feeding end of the feeding transition part 6, the feeding transition part 6 conveys the battery string along the second horizontal direction to the discharging end, and the subsequent typesetting picking mechanism picks up the battery string from the discharging end of the feeding transition part 6.

[0126] Using the conveyor belt as the feeding transition part 6, the feeding transition part 6 can carry at least two strings of battery strings along the second horizontal direction, so as to realize the buffering of the battery string, so that the subsequent typesetting picking mechanism can timely obtain the battery string from the feeding transition part 6, and prevent the occurrence of feeding waiting. In addition, the typesetting picking mechanism picks up the battery string from the discharging end of the feeding transition part 6 each time, thus simplifying the movement control strategy of the typesetting picking mechanism.

[0127] Of course, if it is not necessary for the loading transition part 6 to implement the feeding and buffering of the battery string, a carrying platform can also be used as the loading transition part 6. By using the carrying platform as the loading transition part 6, the installation space occupied by the loading transition part 6 can be reduced. In this way, a storage box can be arranged on the side of the loading transition part 6 to facilitate the recycling of unqualified battery strings into the storage box, or buffering the battery strings that the typesetting picking mechanism fails to pick up into the storage box.

[0128] Optionally, the battery string feeding device in the embodiment of the present application further includes a detection mechanism, and the detection mechanism is arranged on the moving path of the second handling mechanism 5. The second handling mechanism 5 is further configured to carry the battery string with the back facing up picked up to the detection mechanism, and the detection mechanism is configured to perform quality detection on the battery string, and the second handling mechanism 5 carries the battery string with qualified detection to the loading transition part 6.

[0129] By setting the detection mechanism, before carrying the battery string to the loading transition part 6, the second handling mechanism 5 first carries the battery string with the back facing up picked up to the detection mechanism, and the detection mechanism performs quality detection on the battery string. The second handling mechanism 5 only carries the battery string with qualified detection to the loading transition part 6, preventing unqualified battery strings with quality defects from flowing into the subsequent typesetting station.

[0130] Optionally, the second handling mechanism 5 places the battery string with unqualified detection at the recycling position.

[0131] When the installation space occupied by the loading transition part 6 is relatively large, for example, when the loading transition part 6 adopts a conveyor belt capable of buffering battery strings, if an NG material box with a fixed position is arranged on the side of the loading transition part 6, the NG material box will inevitably interfere with the handling of the second handling mechanism 5. To solve this problem, optionally, the battery string feeding device in the embodiment of the present application further includes a telescopic driving mechanism. As Figure 4 shown, the telescopic driving mechanism is arranged below the loading transition part 6, and the telescopic driving mechanism is used to carry the NG material box 110 and drive the NG material box 110 to translate along the second horizontal direction (such as the Y-axis direction) to drive the NG material box 110 to switch between the material receiving position outside the loading transition part 6 and the avoiding position below the loading transition part 6.

[0132] Specifically, when the battery string on the second handling mechanism 5 is determined to be an unqualified battery string after detection, the telescopic driving mechanism drives the NG material box 110 to switch to the material receiving position outside the loading transition part 6, and the second handling mechanism 5 places the unqualified battery string into the NG material box 110 to implement the recycling and buffering of the unqualified battery string. After receiving the unqualified battery string, the telescopic driving mechanism drives the NG material box 110 to retract to the avoiding position below the loading transition part 6 again.

[0133] It can be seen that by arranging a telescopic driving mechanism below the loading transition part 6 and setting the NG material box 110 on the moving part of the telescopic driving mechanism, the recycling of unqualified battery strings is realized, and the normal handling of the second handling mechanism 5 will not be interfered with.

[0134] When the installation space occupied by the loading transition part 6 is small, for example, when the loading transition part 6 adopts a carrying platform that can only carry one string of battery strings, there is a large enough installation space on the side of the loading transition part 6. Therefore, a storage box that avoids the handling path of the second handling mechanism 5 can be directly arranged on the side of the loading transition part 6. The second handling mechanism 5 can place the unqualified battery strings into the storage box. In addition, when the carrying platform already carries qualified battery strings, the second handling mechanism 5 can also cache the qualified battery strings in the storage box.

[0135] As Figure 4 and Figure 6 shown, optionally, the detection mechanism includes an EL detection camera 8, and a power-on component 9 is arranged on the second handling mechanism 5. The power-on component 9 is configured to power on the battery strings on the second handling mechanism 5. The EL detection camera 8 is configured to obtain an infrared image of the battery strings in the powered-on state to implement quality detection of the battery strings.

[0136] Through the cooperation of the EL detection camera 8 and the power-on component 9, the quality detection of the battery strings is realized, so as to ensure that only the battery strings that pass the detection enter the subsequent typesetting station. In addition, the power-on component 9 is arranged on the second handling mechanism 5, and the EL detection camera 8 is arranged at the detection station. Therefore, the second handling mechanism 5 can complete the detection of the battery strings during the handling process of the battery strings, without having to transfer the battery strings to an additional detection table, thereby improving the detection efficiency and avoiding the additional grasping and placing of the battery strings, which is beneficial to reducing the fragmentation rate of the battery wafers.

[0137] Optionally, the power-on component 9 includes a first clamping member 91 and a second clamping member 92, wherein: the first clamping member 91 is arranged at the first end of the second handling mechanism 5, the first clamping member 91 is electrically connected to the positive pole of the power supply, and the first clamping member 91 is configured to clamp the extended welding tape at the first end of the battery string. The second clamping member 92 is arranged at the second end of the second handling mechanism 5, the second clamping member 92 is electrically connected to the negative pole of the power supply, and the second clamping member 92 is configured to clamp the extended welding tape at the second end of the battery string.

[0138] When the first clamping member 91 and the second clamping member 92 clamp the extended welding tapes at both ends of the battery string at the same time, the power supply can power on the battery string.

[0139] As Figure 4As shown, optionally, the sizing mechanism 7 includes a first sizing conveyor line 71, a first sizing unit 72, a turning conveyor unit, a second sizing conveyor line 73, and a second sizing unit 74, where: The first sizing conveyor line 71 is configured to receive the battery string carried by the first handling mechanism 4 and sequentially convey the battery string along the first horizontal direction to the first sizing station A and the transfer station B. The first sizing unit 72 is arranged at the first sizing station A and above the first sizing conveyor line 71, and the first sizing unit 72 is configured to size the front side of the battery string. The turning conveyor unit is arranged at the transfer station B, and the turning conveyor unit is configured to pick up the battery string that has been sized on the front side at the transfer station B, and after turning the battery string so that its back side is facing up, convey the battery string onto the second sizing conveyor line 73. The second sizing conveyor line 73 is configured to sequentially convey the battery string along the first horizontal direction to the second sizing station C and the blanking station D. The second sizing unit 74 is arranged at the second sizing station C and above the second sizing conveyor line 73, and the second sizing unit 74 is configured to size the back side of the battery string. The second handling mechanism 5 picks up the sized battery string with its back side facing up from the blanking station D of the second sizing conveyor line 73 and conveys the picked-up battery string with its back side facing up onto the loading transition section 6.

[0140] It can be seen that after the first handling mechanism 4 conveys the battery string with its front side facing up onto the first sizing conveyor line 71, the front side of the battery string is sized on the first sizing conveyor line 71. The turning conveyor unit turns the battery string and conveys the turned battery string onto the second sizing conveyor line 73, and the second sizing conveyor line 73 conveys the turned battery string to the second sizing station for sizing the back side.

[0141] Through the cooperation of the first sizing conveyor line 71, the first sizing unit 72, the turning conveyor unit, the second sizing conveyor line 73, and the second sizing unit 74, the sizing mechanism 7 realizes continuous sizing of both surfaces of the battery string, and realizes turning of the battery string during the sizing process, so that the back side of the battery string is facing up to meet the requirements of the subsequent layout.

[0142] The first sizing unit 72 and the second sizing unit 74 can adopt screen printing devices, which can accurately print the adhesive material onto the solder tape, reducing the amount of adhesive material used on the premise of ensuring the bonding effect on the solder tape. The first sizing unit 72 and the second sizing unit 74 can also adopt dispensing devices or coating devices.

[0143] Such as Figure 4As shown, optionally, the flipping and conveying unit includes a flipping unit 75 and a conveying unit 76, where: both the conveying unit 76 and the second sizing and conveying line 73 are located above the first sizing and conveying line 71, and the conveying directions of the conveying unit 76 and the second sizing and conveying line 73 are opposite to the conveying direction of the first sizing and conveying line 71. The output end of the conveying unit 76 is docked with the input end of the second sizing and conveying line 73. The flipping unit 75 is configured to pick up the battery string that has completed front-side sizing at the transfer station B, and flip the battery string so that the back side is facing up. The flipping unit 75 is also configured to transport the flipped battery string to the conveying surface of the conveying unit 76. The conveying unit 76 is configured to convey the battery string onto the second sizing and conveying line 73.

[0144] It can be seen that after the flipping unit 75 completes the flipping operation on the battery string, it directly places the battery string on the conveying surface of the conveying unit 76. The conveying unit 76 then conveys the battery string onto the second sizing and conveying line 73 that is docked with it. That is, during the process of transferring the flipped battery string from the first sizing and conveying line 71 to the second sizing and conveying line 73, there is no need to pick up the battery string, thus reducing the risk of damage to the battery string.

[0145] In addition, the conveying unit 76 and the second sizing and conveying line 73 are arranged above the first sizing and conveying line 71, and the conveying directions of the conveying unit 76 and the second sizing and conveying line 73 are set to be opposite to the conveying direction of the first sizing and conveying line 71, reducing the overall size of the sizing mechanism 7.

[0146] As Figures 9 to 11 shown, optionally, the flipping unit 75 includes a lifting drive unit 751, a lifting frame 752, a flipping frame 753, a flipping drive unit 754, and a suction component 755, where: the lifting frame 752 is connected to the moving part of the lifting drive unit 751, the flipping frame 753 is rotatably connected to the lifting frame 752, the flipping frame 753 is in transmission connection with the flipping drive unit 754 arranged on the lifting frame 752, and the suction component 755 is installed on the flipping frame 753. The lifting drive unit 751 is configured to drive the suction component 755 to descend, so that the suction component 755 adsorbs the battery string from the transfer station B. The flipping drive unit 754 is configured to drive the suction component 755 to flip, so as to drive the battery string adsorbed on the suction component 755 to flip, making the back side of the battery string face up. The lifting drive unit 751 is also configured to drive the suction component 755 to rise to place the flipped battery string on the conveying surface of the conveying unit 76.

[0147] The working process of the flipping unit 75 is as follows:

[0148] When the first sizing and conveying line 71 conveys the battery string that has completed front-side sizing to the transfer station B, the lifting drive unit 751 drives the suction component 755 to descend, so that the suction component 755 adsorbs and picks up the battery string from the transfer station B.

[0149] Subsequently, the flip driving unit 754 drives the suction component 755 to flip, so as to cause the battery string adsorbed on the suction component 755 to flip, so that the back of the battery string faces upward.

[0150] Next, the lifting drive unit 751 drives the suction assembly 755 to rise so as to lift the flipped battery string to above the conveying surface of the conveying portion 76 .

[0151] Finally, the lifting drive unit 751 drives the suction assembly 755 to descend and return to its original position, so that the battery string falls onto the conveying surface of the conveying portion 76 .

[0152] Optionally, the suction assembly 755 includes a plurality of suction cups spaced apart along the first horizontal direction on the flip frame 753 , and the plurality of suction cups cooperate to absorb the battery string of the transfer station B.

[0153] Optionally, the suction assembly 755 is provided in 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 to each other. When the suction surface of the first suction assembly is flipped to face downward, the suction surface of the second suction assembly is flipped to face upward. In this way, the first suction assembly and the second suction assembly can alternately adsorb the battery string from the transfer station B, and alternately flip the battery string to face upward and place it on the conveying surface of the conveying part 76, thereby improving the flipping and transfer efficiency of the battery string and ensuring the gluing rhythm of the second gluing part 74.

[0154] Continue to refer Figures 9 to 11 As shown, optionally, the conveying part 76 includes a fixed frame 761, an opening and closing unit 762, a first connecting frame 763, a second connecting frame 764, a first conveyor belt 765 and a second conveyor belt 766, wherein the opening and closing unit 762 is arranged on the fixed frame 761. The first connecting frame 763 and the second connecting frame 764 are both slidably connected to the bottom of the fixed frame 761 along the second horizontal direction (such as the Y-axis direction), and are respectively connected to the opening and closing unit 762 in a transmission manner. The opening and closing unit 762 is configured to drive the first connecting frame 763 and the second connecting frame 764 to slide apart to both sides or slide close to the middle along the second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction (such as the X-axis direction).

[0155] The first conveyor belt 765 is installed on the first connecting frame 763 along the first horizontal direction, and the second conveyor belt 766 is installed on the second connecting frame 764 along the first horizontal direction. A lifting space is formed between the first conveyor belt 765 and the second conveyor belt 766 for the turning part 75 to pass through. The upper surface of the first conveyor belt 765 and the upper surface of the second conveyor belt 766 constitute the conveying surface of the conveying part 76.

[0156] The cooperation process of the conveying part 75 and the turning part 76 is as follows:

[0157] The opening and closing unit 762 drives the first connecting frame 763 and the second connecting frame 764 to slide apart to both sides, and a lifting space with a first width is formed between the first conveyor belt 765 and the second conveyor belt 766, and the first width is greater than the width of the battery string.

[0158] Subsequently, the flipping unit 75 lifts the flipped battery string through the lifting space to above the first conveyor belt 765 and the second conveyor belt 766. Since the width of the lifting space is greater than the width of the battery string, the battery string can pass through the lifting space upward and reach above the first conveyor belt 765 and the second conveyor belt 766.

[0159] Next, the opening and closing unit 763 drives the first connecting frame 763 and the second connecting frame 764 to slide toward the middle, so that a lifting space with a second width is formed between the first conveyor belt 765 and the second conveyor belt 766, and the second width is smaller than the width of the battery string.

[0160] Finally, the turning part 75 descends 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 765 and the second conveyor belt 766 respectively, and then fall onto the first conveyor belt 765 and the second conveyor belt 766.

[0161] It can be seen that when the battery string is transferred from the flipping portion 75 to the conveying portion 76 , there is no need to pick up the battery string, thereby preventing damage to the battery string.

[0162] The opening and closing unit 762 can adopt various existing driving devices that can drive the first connecting frame 763 and the second connecting frame 764 to slide toward the middle or slide toward both sides and separate along the second horizontal direction. For example, the opening and closing unit 762 includes two linear driving modules with opposite driving directions arranged on the fixed frame 761. The two linear driving modules are respectively connected to the first connecting frame 763 and the second connecting frame 764 in a transmission manner. The two linear driving modules synchronously drive the first connecting frame 763 and the second connecting frame 764 to slide in opposite directions along the second horizontal direction, thereby adjusting the width of the lifting space between the first conveyor belt 765 and the second conveyor belt 766. The linear driving module can be, for example, a cylinder, a screw motor, etc.

[0163] The present application also provides a typesetting device, such as Figure 2 and Figure 8 As shown, the typesetting device in the embodiment of the present application includes the battery string feeding device 10 and the typesetting picking mechanism 20 in any of the above embodiments. Wherein:

[0164] Two battery string feeding devices 10 are arranged side by side at intervals along the second horizontal direction (such as the Y-axis direction) and are arranged in a mirror image. The typesetting picking mechanism 20 is arranged above the two feeding transition parts 6 and is located between the two second handling mechanisms 5.

[0165] The typesetting picking mechanism 20 includes a first picking part 210 and a second picking part 220. The first picking part 210 is used to pick up and typeset the battery string from one of the feeding transition parts 6, and the second picking part 220 is used to pick up and typeset the battery string from the other feeding transition part 6.

[0166] Since the two battery string feeding devices 10 are arranged side by side at intervals along the second horizontal direction and are arranged in a mirror image, the feeding transition parts 6 of the two battery string feeding devices 10 can supply the battery strings synchronously. The typesetting picking mechanism 20 can synchronously pick up the battery strings from the feeding transition parts 6 of the two battery string feeding devices 10 through the first picking part 210 and the second picking part 220, and perform typesetting, thereby improving the typesetting efficiency.

[0167] Continue to refer to Figure 8 As shown, optionally, the typesetting picking mechanism 20 further includes a second translation driving part 230, a distance separating driving part 240, a third lifting driving part 250, and a fourth lifting driving part 260, where: the distance separating driving part 240 is connected to the moving part of the second translation driving part 230, the third lifting driving part 250 and the fourth lifting driving part 260 are connected to the moving part of the distance separating driving part 240, the first picking part 210 is connected to the moving part of the third lifting driving part 250, and the second picking part 220 is connected to the moving part of the fourth lifting driving part 260. The second translation driving part 230 is used to drive the first picking part 210 and the second picking part 220 to translate synchronously along the first horizontal direction. The third lifting driving part 250 is used to drive the first picking part 210 to lift, and the fourth lifting driving part 260 is used to drive the second picking part 220 to lift. The distance separating driving part 240 is used to drive the first picking part 210 and the second picking part 220 to translate in opposite directions along the second horizontal direction when the first picking part 210 and the second picking part 220 are at different heights, so that the first picking part 210 and the second picking part 220 move closer to the middle or separate from each other. The first picking part 210 and the second picking part 220 are also respectively configured to drive the picked battery strings to rotate along the horizontal direction.

[0168] The optional working process of the typesetting picking mechanism 20 is as follows:

[0169] When it is necessary to pick up and transport the battery strings on the two loading transition parts 6, the third lifting drive part 250 and the fourth lifting drive part 260 first drive the first picking part 210 and the second picking part 220 to different heights. Subsequently, the spacing drive part 240 drives the first picking part 210 and the second picking part 220 to slide closer to the middle along the second horizontal direction, so that the first picking part 210 and the second picking part 220 are partially staggered.

[0170] Then, the second translation drive part 230 drives the first picking part 210 and the second picking part 220 to move along the first horizontal direction towards the two loading transition parts 6 until they reach above the two loading transition parts 6. Since the first picking part 210 and the second picking part 220 are partially staggered in the second horizontal direction, when the first picking part 210 and the second picking part 220 pass between the two second handling mechanisms 5, they will not interfere with the two second handling mechanisms 5.

[0171] After the first picking part 210 and the second picking part 220 move to place above the two loading transition parts 6, the first picking part 210 and the second picking part 220 synchronously rotate to extend along the first horizontal direction, and the first picking part 210 and the second picking part 220 are respectively located above one of the loading transition parts 6.

[0172] Subsequently, the third lifting drive part 250 and the fourth lifting drive part 260 respectively drive the first picking part 210 and the second picking part 220 to descend towards the corresponding loading transition part 6, so that the first picking part 210 and the second picking part 220 respectively pick up the battery strings from the corresponding loading transition part 6.

[0173] Then, the second translation drive part 230 drives the first picking part 210 and the second picking part 220 to move away from the two loading transition parts 6 along the first horizontal direction. After the first picking part 210 and the second picking part 220 pass between the two second handling mechanisms 5, the first picking part 210 and the second picking part 220 synchronously rotate to extend along the second horizontal direction. Subsequently, the spacing drive part 240 drives the first picking part 210 and the second picking part 220 to slide apart along the second horizontal direction, so that the two battery strings picked up by the first picking part 210 and the second picking part 220 are arranged at intervals along the second horizontal direction.

[0174] It can be seen that by setting the typesetting picking mechanism 20, the typesetting picking mechanism 20 realizes the synchronous picking of two battery strings on the two feeding transition parts 6 and the typesetting of the two picked battery strings, thereby improving the typesetting efficiency. In addition, since the first picking part 210 and the second picking part 220 of the typesetting picking mechanism 20 can move closer to the middle and partially intersect, when the distance between the two second handling mechanisms 5 is set to be small, it can also ensure that the first picking part 210 and the second picking part 220 of the typesetting picking mechanism 20 can smoothly pass between the two second handling mechanisms 5, thereby reducing the size installation space of the battery string feeding device in the embodiment of the present application.

[0175] The second translation driving part 230 can adopt various existing linear driving devices that can drive the distance dividing driving part 240 to translate in the first horizontal direction. For example, the second translation driving part 230 includes two synchronous belt driving modules arranged at intervals in the second horizontal direction. One end of the fixed part of the distance dividing driving part 240 is connected to the driving end of one synchronous belt driving module, and the other end of the fixed part of the distance dividing driving part 240 is connected to the driving end of the other synchronous belt driving module. The two synchronous belt driving modules synchronously drive the distance dividing driving part 240 to translate in the first horizontal direction.

[0176] The third lifting driving part 250 and the fourth lifting driving part 260 can both adopt various existing linear driving modules that can drive the first picking part 210 and the second picking part 220 to lift, such as a cylinder module or a screw motor module, etc.

[0177] Optionally, the structures of the first picking part 210 and the second picking part 220 are the same. Taking the first picking part 210 as an example, it includes a mounting bracket and a plurality of suction cups. Among them, the mounting bracket is connected to the driving end of the third lifting driving part 250, and the plurality of suction cups are arranged at intervals along the length direction of the mounting bracket on the mounting bracket.

[0178] Optionally, the distance dividing driving part 240 includes a synchronous belt driving component and a synchronous belt, wherein: the synchronous belt driving component is arranged on the movable part of the second translation driving part 230, the synchronous belt is installed on the synchronous belt driving component along the second horizontal direction, the fixed part of the third lifting driving part 250 is fixedly connected to the first side belt body of the synchronous belt, and the fixed part of the fourth lifting driving part 260 is fixedly connected to the second side belt body of the synchronous belt. The synchronous belt driving component is used to drive the synchronous belt to rotate to drive the first picking part 210 and the second picking part 220 to move closer to the middle or separate from each other.

[0179] Such as Figures 2 to 4As shown, optionally, the typesetting device in the embodiments of the present application further includes a regular conveying mechanism 30, a welding picking mechanism 40, and a welding mechanism 50, where: The typesetting picking mechanism 20 is configured to place two battery strings picked from the output end of the feeding transition part 6 on the regular conveying mechanism 30 respectively according to the requirements of the typesetting positive and negative polarities. The regular conveying mechanism 30 is configured to receive and regularize the battery strings placed by the typesetting picking mechanism 20. The welding picking mechanism 40 includes string picking components arranged in one-to-one correspondence with each battery string in the battery string array. The regular conveying mechanism 30 is further configured to convey the regularized battery strings to the string picking station according to the requirements of the typesetting position. The welding picking mechanism 40 moves to drive the string picking component corresponding to the battery string at the string picking station to move to the string picking station to pick up the battery string. The welding picking mechanism 40 moves to drive the string picking component picking up the battery string to the welding station, and the welding mechanism 50 welds the bus bar to the extended welding strip at the end of the battery string located at the welding station. The welding picking mechanism 40 is further configured to, after the bus bars of the battery strings picked up by each string picking component are all welded, move to lay the battery strings picked up by each string picking component on the glass plate.

[0180] After the typesetting picking mechanism 20 places two battery strings picked from the feeding transition part 6 on the regular conveying mechanism 30 respectively according to the requirements of the typesetting positive and negative polarities, the regular conveying mechanism part 30 regularizes the battery strings according to the requirements of the typesetting position and conveys the regularized battery strings to the string picking station. After the welding picking mechanism 40 picks up the battery string from the string picking station, it conveys the battery string to the welding station. The welding mechanism 50 directly welds the bus bar to the battery string on the welding picking mechanism 40. After all the bus bars are welded, the welding picking mechanism lays all the battery strings on the glass plate. Thus, the typesetting and bus bar welding of a battery string array are completed.

[0181] It can be seen that the typesetting device in the embodiments of the present application realizes the automatic feeding, automatic typesetting, and automatic welding of the bus bar of the battery string in sequence, without manual interference throughout the process, thereby greatly improving the typesetting efficiency.

[0182] Optionally, as Figure 2 and Figure 3 shown, the sizing mechanism 7 extends along the first horizontal direction and is located on both sides of the regular conveying mechanism 30, the welding picking mechanism 40, and the welding mechanism 50, without increasing the length of the typesetting device in the embodiments of the present application along the first horizontal direction.

[0183] Optionally, the regular conveying mechanism 30 includes a first regular conveying part and a second regular conveying part with the same structure, and the first regular conveying part and the second regular conveying part are arranged side by side along the second horizontal direction.

In addition, the regular platform is further configured to be rotatable so as to adjust the angle of the battery strings carried thereon.
