Description

Technical Field

[0001] This application relates to the field of photovoltaic module production equipment, specifically a battery string feeding device and a layout device. Background Technology

[0002] When laying out battery strings, a battery string feeding device is needed to supply battery strings to the layout and picking mechanism. For example... Figure 1 As shown, a conventional battery string feeding device includes a stringing section 1, a string cutter 2, a first conveyor line 3, a battery string handling mechanism 104, a second conveyor line 105, and a feeding conveyor line 106. The first conveyor line 3 is located after the stringing section 1. The string cutter 2 is disposed between the output end of the stringing section 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 connected to the input end of the feeding conveyor line 106.

[0003] After the front-facing battery cells and solder strips are welded together on the stringing section 1, they are cut into battery strings of predetermined lengths by the string cutter 2 and then flow into the first conveyor line 3. The battery string transport mechanism 104 picks up the battery string from the first conveyor line 3, flips the battery string 180° so that the back of the battery string is facing up, and then transports the battery string to the second conveyor line 105. The second conveyor line 105 transports the battery string to the loading conveyor line 106, where the layout and picking mechanism picks up the battery string from the loading conveyor line 106 and arranges it.

[0004] Traditional battery string feeding devices are relatively long and take up a lot of space. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a battery string feeding device and a sorting equipment, which adopts the following technical solution:

[0006] A battery string feeding device includes a stringing section, a string cutter, a first conveyor line, a first conveying mechanism, a second conveying mechanism, and a feeding transition section, wherein:

[0007] The first conveyor line is located after the stringing section. The string cutter is located between the stringing section and the first conveyor line. The front-facing battery cells are welded into strings on the stringing section by welding strips, and then cut into battery strings of predetermined length by the string cutter and flow into the first conveyor line.

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

[0009] The feeding transition section is located above the first conveyor line, and the first handling mechanism is located between the first conveyor line and the feeding transition section.

[0010] The first conveying mechanism is configured to pick up a battery string from the first conveyor line and flip the picked-up battery string to face down; or, the battery string feeding device further includes a gluing mechanism, the first conveying mechanism is configured to convey the picked-up battery string to the gluing mechanism, the gluing mechanism is configured to apply glue to the front of the battery string, and after flipping the battery string to face down after the front gluing is completed, apply glue to the back of the battery string.

[0011] The second transport mechanism is configured to pick up the battery strings with the back facing up from the first transport mechanism or from the glue application mechanism, and to transport the battery strings to the loading transition section.

[0012] The battery string feeding device of this application has a feeding transition section and a first conveyor line arranged in layers, one above the other. After the battery strings are cut by the string cutter, they flow into the first conveyor line and are then conveyed to the area below the feeding transition section. Subsequently, a first conveying mechanism flips the battery strings so that their backs face up, or conveys the battery strings to a gluing mechanism, which flips the battery strings during the gluing process so that their backs face up. Then, a second conveying mechanism conveys the battery strings with their backs facing up from the first conveying mechanism or the gluing mechanism to the feeding transition section. During the layout process, the layout picking mechanism can pick up the battery strings from the feeding transition section and perform layout of the battery strings.

[0013] Because the feeding transition section and the first conveyor line are arranged in layers, the length and space occupied by the battery string feeding device of this application are significantly reduced compared to traditional battery string feeding devices. In addition, when a glue application mechanism is included, the battery string feeding device of this application can also be compatible with the layout and feeding of OBB (no main grid) battery strings that require glue application.

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

[0015] For battery strings that do not require adhesive application, the first adsorption unit picks up the battery string from the first conveyor line and flips it so that the back side faces upward, driven by the coordinated operation of the first translation drive unit, the first lifting drive unit, and the first flipping drive unit. Finally, the second transport mechanism moves the battery string to the loading transition unit. For gridless battery strings that require adhesive application, the first adsorption unit picks up the battery string from the first conveyor line and transports it to the adhesive application mechanism. During the adhesive application process, the adhesive application mechanism flips the battery string so that the back side faces upward, and the second transport mechanism moves it to the loading transition unit.

[0016] In some embodiments, the second conveying mechanism includes a second lifting drive unit, a rotary drive unit, a rotating shaft, a second adsorption unit, and two swing arms, wherein: the rotary drive unit is connected to a movable component of the second lifting drive unit, the rotating shaft is connected to the movable component of the rotary drive unit, and extends along a first horizontal direction; the upper ends of the two swing arms are fixedly connected to the rotating shaft, the second adsorption unit is disposed between the two swing arms along the first horizontal direction, and the lower ends of the two swing arms are rotatably connected to the two ends of the second adsorption unit respectively; the rotary drive unit is configured to drive the two swing arms to swing via the rotating shaft, so as to move the second adsorption unit between the first conveying mechanism and the feeding transition section; or the rotary drive unit is configured to drive the two swing arms to swing via the rotating shaft, so as to move the second adsorption unit between the feeding transition section and the adhesive application mechanism; the second lifting drive unit is configured to drive the second adsorption unit to lift and lower.

[0017] Driven by the combined lifting and rotating drives, the second suction unit, connected to the lower end of the swing arm, moves and moves between the first conveying mechanism and the loading transition section, thereby picking up the flipped battery strings from the first conveying mechanism and transporting them to the loading transition section. Alternatively, it moves and moves between the loading transition section and the gluing mechanism, thereby picking up the glued and flipped battery strings from the gluing mechanism and transporting them to the loading transition section. Compared to conventional translational conveying mechanisms, the second conveying mechanism, which uses a swinging motion, has the advantages of simple structure and small space occupation.

[0018] In some embodiments, the second conveying mechanism further includes a horizontal limiting component, which includes a fixed frame, a connector, and a connecting rod, wherein: the fixed frame is disposed on the movable part of the second lifting drive unit, and the upper end of the connector is hinged to the fixed frame; the first end of the connecting rod is hinged to the lower end of the connector, and the second end of the connecting rod is fixedly connected to the end of the second adsorption unit; the distance between the upper hinge point of the connector 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 connector and the rotation center of the second adsorption unit in the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0019] Because the two ends of the second adsorption unit are rotatably connected to the lower ends of the two swing arms, the horizontal limiting component achieves horizontal limiting of the second adsorption unit during the swinging process of the rotary drive unit driving the two swing arms, so that the second adsorption unit always remains in a horizontal state during the swinging process. This ensures that after the second adsorption unit moves into place, it can stably pick up the battery strings on the first conveying mechanism or the gluing mechanism in a horizontal state, and smoothly place the picked-up battery strings onto the loading transition part in a horizontal state.

[0020] In some embodiments, the connector is a cylinder, the cylinder body is hinged to the fixed frame, and the extension rod of the cylinder is hinged to the first end of the connecting rod; after the second adsorption part moves into 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 a connecting component, the extension length of the cylinder's telescopic rod remains constant during the swinging process of the second adsorption unit, thus ensuring that the second adsorption unit remains horizontal throughout the swinging process. When the second adsorption unit swings to a predetermined position, such as a predetermined manual inspection station, the cylinder can control the extension and retraction of the telescopic rod, thereby causing the second adsorption unit to flip outward from a horizontal state to a vertical state, facilitating the inspection of the battery strings adsorbed on the second adsorption unit.

[0022] In some embodiments, the feeding transition section is a conveyor belt for conveying battery strings along a second horizontal direction, which is perpendicular to the first horizontal direction; the width of the conveying surface of the feeding transition section along the first horizontal direction is at least equal to the length of one battery string, and the conveying surface of the feeding transition section along the second horizontal direction can support at least two battery strings; or, the feeding transition section is a support platform for supporting one battery string.

[0023] A conveyor belt is used as the loading transition section, which can carry at least two battery strings along the second horizontal direction. This buffers the battery strings, ensuring that the subsequent layout and picking mechanism can promptly retrieve them from the loading transition section and prevent supply delays. Using a support platform as the loading transition section reduces the installation space it occupies. This allows for the installation of storage boxes on the side of the loading transition section without interfering with the handling by the second transport section.

[0024] In some embodiments, the battery string feeding device further includes a detection mechanism disposed on the movement path of the second conveying mechanism; the second conveying mechanism is further configured to convey picked-up battery strings with their backs facing up to the detection mechanism, the detection mechanism is configured to perform quality inspection on the battery strings, and the second conveying mechanism conveys qualified battery strings to the feeding transition section.

[0025] By setting up an inspection mechanism, the second transport mechanism can transport the picked-up battery strings with their backs facing up to the inspection mechanism, where the inspection mechanism performs quality inspection on the battery strings. The second transport mechanism only transports the qualified battery strings to the loading transition section to prevent 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 a power-on component is provided on the second transport mechanism, the power-on component being configured to power the battery string on the second transport mechanism; the EL detection camera is configured to acquire infrared images of the battery string in the powered state to perform quality detection on the battery string.

[0027] By combining an EL inspection camera and a power-on component, quality inspection of battery strings is achieved, ensuring that only qualified battery strings proceed to the subsequent layout stage. Furthermore, the power-on component is located in the second transport mechanism, while the EL inspection camera is positioned at the inspection station. Therefore, the second transport mechanism can complete the inspection of battery strings during transport, eliminating the need to transfer them to a dedicated inspection table. This improves inspection efficiency and avoids the additional handling of battery strings during inspection, thus reducing the breakage rate of the battery cells.

[0028] In some embodiments, the power-conducting assembly includes a first clamping member and a second clamping member, wherein: the first clamping member is disposed at a first end of the second transport mechanism, the first clamping member is electrically connected to the positive terminal of the power supply, and the first clamping member is configured to clamp the extended solder strip at the first end of the battery string; the second clamping member is disposed at a second end of the second transport mechanism, the second clamping member is electrically connected to the negative terminal of the power supply, and the second clamping member is configured to clamp the extended solder strip at the second end of the battery string.

[0029] A simple power-conducting assembly is provided. After the second transport mechanism picks up the battery string, the first clamp and the second clamp respectively clamp the long solder strips at both ends of the battery string, and the power supply can be implemented to the battery string through the first clamp and the second clamp.

[0030] In some embodiments, the battery string feeding device further includes a telescopic drive mechanism; the telescopic drive mechanism is disposed below the feeding transition section, and the telescopic drive mechanism is used to carry the NG material box and drive the NG material box to translate along a second horizontal direction, so as to drive the NG material box to switch between a receiving position located outside the feeding transition section and an avoidance position located below the feeding transition section, wherein the second horizontal direction is perpendicular to the first horizontal direction; or, the battery string feeding device further includes at least one storage box fixedly disposed on the side of the feeding transition section.

[0031] When the loading transition section occupies a large installation space, such as when the loading transition section uses a conveyor belt capable of buffering battery strings, placing the NG (non-conforming) material box on the side of the loading transition section will inevitably interfere with the handling of the second handling mechanism. By placing the telescopic drive mechanism below the loading transition section, the telescopic drive mechanism can switch the NG material box between a receiving position outside the loading transition section and a clearance position below the loading transition section. This not only achieves the recycling and buffering of non-conforming battery strings, but also does not obstruct the normal handling of the second handling mechanism. When the loading transition section occupies a small installation space, such as when the loading transition section uses a support platform that only carries one battery string, there is sufficient installation space on the side of the loading transition section. Therefore, placing a storage box on the side of the loading transition section can effectively implement the recycling and buffering of non-conforming battery strings.

[0032] In some embodiments, the adhesive application mechanism includes a first adhesive application conveyor line, a first adhesive application section, a flipping conveyor section, a second adhesive application conveyor line, and a second adhesive application section, wherein: the first adhesive application conveyor line is configured to receive battery strings transported by a first handling mechanism and to sequentially transport the battery strings to a first adhesive application station and a transfer station along a first horizontal direction; the first adhesive application section is disposed at the first adhesive application station and located above the first adhesive application conveyor line, and is configured to apply adhesive to the front side of the battery strings; the flipping conveyor section is disposed at the transfer station and is configured to pick up the battery strings located at the transfer station that have completed front-side adhesive application, and after flipping the battery strings to face-up, transport the battery strings to the second adhesive application conveyor line; the second adhesive application conveyor line is configured to sequentially transport the battery strings to a second adhesive application station and a unloading station along a first horizontal direction, and the second adhesive application section is disposed at the second adhesive application station and located above the second adhesive application conveyor line, and is configured to apply adhesive to the back side of the battery strings; the second handling mechanism picks up the battery strings with face-up adhesive application from the unloading station.

[0033] After the battery string completes front-side adhesive application on the first adhesive conveyor line, the flipping conveyor flips the battery string and transports it to the second adhesive conveyor line. The second adhesive conveyor line then transports the flipped battery string to the second adhesive station for back-side adhesive application. The second adhesive conveyor line carries and transports the battery string to perform back-side adhesive application. In other words, through the cooperation of the first adhesive conveyor line, the first adhesive application unit, the flipping conveyor line, the second adhesive conveyor line, and the second adhesive application unit, the adhesive application mechanism achieves continuous adhesive application to both surfaces of the battery string, and flips the battery string during the adhesive application process so that the back side of the battery string faces upwards.

[0034] In some embodiments, the flipping conveyor includes a flipping section and a conveying section, wherein: the conveying section and the second adhesive conveying line are both located above the first adhesive conveying line, and the conveying directions of the conveying section and the second adhesive conveying line are opposite to the conveying direction of the first adhesive conveying line; the output end of the conveying section is connected to the input end of the second adhesive conveying line; the flipping section is configured to pick up the battery string that has completed front-side adhesive application at the transfer station, and to flip the battery string so that the back side faces upward; the flipping section is also configured to transport the flipped battery string to the conveying surface of the conveying section; the conveying section is configured to convey the battery string to the second adhesive conveying line.

[0035] After the flipping unit flips the battery string, it places the battery string on the conveying surface of the conveying unit, which then directly conveys the battery string to the second adhesive conveying 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.

[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 assembly, wherein: the lifting frame is connected to a movable part of the lifting drive unit, the flipping frame is rotatably connected to the lifting frame, the flipping frame is drively connected to the flipping drive unit disposed on the lifting frame, and the suction assembly is mounted 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 transfer station; the flipping drive unit is configured to drive the suction assembly to flip, so that the battery string adsorbed on the suction assembly flips, so that the back of the battery string faces upward; the lifting drive unit is also configured to drive the suction assembly to rise, so that the flipped battery string is placed on the conveying surface of the conveying unit.

[0037] By configuring the flipping part, the flipping part can pick up the battery string from the transfer station, flip the battery string so that the back is facing up, and then place the battery string on the conveying surface of the conveying part.

[0038] In some embodiments, the conveying unit 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 disposed 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 a second horizontal direction and are respectively drivenly connected to the opening and closing unit, the opening and closing unit being 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 mounted on the first connecting frame along the first horizontal direction, and the second conveyor belt is mounted on the second connecting frame along the first horizontal direction. Above, a lifting space is formed between the first conveyor belt and the second conveyor belt for the flipping part to pass through; when the opening and closing unit 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. The first width is greater than the width of the battery string. 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 closer to 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 less than the width of the battery string. 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] By configuring the conveyor section, the flipping section can lift the flipped battery string above the conveyor surface of the conveyor section, and when the flipping section descends to its original position, the battery string on the flipping section automatically falls onto the conveyor surface of the conveyor section. In other words, during the process of switching the battery string from the flipping section to the conveyor section, there is no need to pick up the battery string a second time, thereby preventing damage to the battery string.

[0040] This application also provides a typesetting device, which includes two battery string feeding devices as described in any one of the above claims and a typesetting picking mechanism, wherein: the two battery string feeding devices are arranged side by side at intervals along a second horizontal direction and are arranged in a mirror image, the second horizontal direction being perpendicular to the first horizontal direction; the typesetting picking mechanism is disposed above the two feeding transition sections and located between the two second conveying mechanisms, the typesetting picking mechanism including a first picking part and a second picking part, the first picking part being used to pick up battery strings from one of the feeding transition sections and type them, and the second picking part being used to pick up battery strings from the other feeding transition section and type them.

[0041] Two battery string feeding devices are arranged side-by-side at intervals along a second horizontal direction and in a mirror configuration, so that the feeding transition sections of the two battery string feeding devices can supply battery strings synchronously. The layout picking mechanism picks up battery strings from the feeding transition sections of the two battery string feeding devices simultaneously through the first picking section and the second picking section, and performs layout, thereby improving layout efficiency.

[0042] In some embodiments, the typesetting pickup mechanism further includes a second translation drive unit, a spacing drive unit, a third lifting drive unit, and a fourth lifting drive unit, wherein: the spacing drive unit is connected to a movable component of the second translation drive unit, the third lifting drive unit and the fourth lifting drive unit are connected to the movable component of the spacing drive unit, the first pickup unit is connected to the movable component of the third lifting drive unit, and the second pickup unit is connected to a movable component of the fourth lifting drive unit; the second translation drive unit is used to drive the first pickup unit and the second pickup unit to translate synchronously along a first horizontal direction; the third lifting drive unit is used to drive the first pickup unit to lift and lower, and the fourth lifting drive unit is used to drive the second pickup unit to lift and lower; the spacing drive unit is used to drive the first pickup unit and the second pickup unit to translate in opposite directions along a second horizontal direction when they are at different heights, so that the first pickup unit and the second pickup unit move closer to the center or separate to both sides; wherein, the second horizontal direction is perpendicular to the first horizontal direction; the first pickup unit and the second pickup unit are also respectively configured to drive the picked-up battery string to rotate along the horizontal direction.

[0043] As can be seen, by configuring the layout and picking mechanism, it achieves simultaneous picking of two battery strings from the two feeding transition sections and layout of the picked-up battery strings, thereby improving layout efficiency. Furthermore, since the first and second picking parts of the layout and picking mechanism can move closer together and partially overlap, even with a smaller distance between the two second conveying mechanisms, it can still be ensured that the first and second picking parts of the layout and picking mechanism can smoothly pass between the two second conveying mechanisms, thereby reducing the size of the battery string feeding device in this embodiment and saving installation space.

[0044] In some embodiments, the pitch drive unit includes a timing belt drive assembly and a timing belt, wherein: the timing belt drive assembly is disposed on the movable part of the second translation drive unit, the timing belt is mounted on the timing belt drive assembly along the second horizontal direction, the fixing part of the third lifting drive unit is fixedly connected to the first side of the timing belt, and the fixing part of the fourth lifting drive unit is fixedly connected to the second side of the timing belt; the timing belt drive assembly is used to drive the timing belt to rotate, so as to drive the first pickup unit and the second pickup unit to move closer to the middle or to separate to both sides.

[0045] A simple and stable pitch drive unit is provided, which drives the synchronous belt to rotate through a synchronous belt drive assembly, thereby causing the first pickup part and the second pickup part, which are 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 separate to both sides.

[0046] In some embodiments, the layout equipment further includes a aligning conveyor, a welding pickup mechanism, and a welding mechanism, wherein: the layout pickup mechanism is configured to pick up two battery strings from the output end of the feeding transition section and place them onto the aligning conveyor according to the layout positive and negative polarity requirements; the aligning conveyor is configured to receive and align the battery strings placed by the layout pickup mechanism; the welding pickup mechanism includes picking components arranged one-to-one with each battery string in the battery string array; the aligning conveyor is further configured to place the battery strings according to the layout position requirements. The complete battery string is transported to the picking station. The welding picking mechanism moves to move the picking assembly corresponding to the battery string at the picking station to the picking station to pick up the battery string. The welding picking mechanism moves to move the picking assembly with the picked-up battery string to the welding station. The welding mechanism welds the busbar to the extended welding strip at the end of the battery string located at the welding station. The welding picking mechanism is also used to move after the busbar welding of the battery strings picked up by each picking assembly is completed, so as to lay the battery strings picked up by each picking assembly on the glass plate.

[0047] The layout and pickup mechanism picks up two battery strings from the feeding transition section and places them onto the alignment conveyor according to the positive and negative polarity requirements. The alignment conveyor then aligns the battery strings according to the layout position requirements and conveys the aligned battery strings to the pickup station. The welding pickup mechanism picks up the battery strings from the pickup station and conveys them to the welding station. The welding mechanism directly welds the busbars to the battery strings on the welding pickup mechanism. After all the busbars are welded, the welding pickup mechanism lays all the battery strings on the glass plate, thus completing the layout and busbar welding of a battery string array.

[0048] As can be seen, the layout equipment of this application realizes automatic feeding, automatic layout and automatic welding of battery strings in sequence, without manual intervention, thereby greatly improving layout efficiency. Attached Figure Description

[0079] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0080] like Figures 2 to 5 As shown, the battery string feeding device in this embodiment includes a stringing section 1, a string cutter 2, a first conveyor line 3, a first conveying mechanism 4, a second conveying mechanism 5, and a feeding transition section 6, wherein:

[0081] The first conveyor line 3 is located after the stringing section 1. The string cutter 2 is located between the stringing section 1 and the first conveyor line 3. After the battery strings with the front facing up are welded into a string on the stringing section 1 by welding strips, they are cut into battery strings of a predetermined length by the string cutter 2 and flow into the first conveyor line 3.

[0082] The first conveyor line 3 is configured to convey battery strings along a first horizontal direction (such as the X-axis direction).

[0083] The feeding transition section 6 is located above the first conveyor line 3, and the first handling mechanism 4 is located between the first conveyor line 3 and the feeding transition section 6.

[0084] The first conveying mechanism 4 is configured to pick up a battery string from the first conveyor line 3 and flip the picked-up battery string so that its back side faces up.

[0085] The second conveying mechanism 5 is configured to pick up the battery string with its back facing up from the first conveying mechanism 4 and to convey the battery string to the loading transition section 6.

[0086] The feeding process of the battery string feeding device in this embodiment is as follows:

[0087] After the battery cells and solder strips are welded into a string on the stringing section 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 transports the battery strings to the area below the loading transition section 6.

[0089] Subsequently, the first conveying mechanism 4 picks up the battery string from the first conveyor line 3 and flips the battery string so that its back faces up.

[0090] Next, the second conveying mechanism 5 picks up the battery string with the back facing up from the first conveying mechanism 4 and transports the battery string to the loading transition section 6.

[0091] Thus, during the layout process, the layout picking mechanism can pick up the battery strings with the back facing up from the feeding transition section 6 and perform layout of the battery strings.

[0092] Since the feeding transition section 6 and the first conveyor line 3 are arranged in layers, the length and space occupied by the battery string feeding device in this embodiment are greatly reduced compared to the traditional battery string feeding device.

[0093] As is known to those skilled in the art, after OBB (no grid) solar cells are welded into strings, the connection between the solder ribbon and the solar cell is relatively weak. Therefore, before the layout is implemented, it is necessary to apply adhesive to the front and back of the solar cell string to further bond the solder ribbon to the solar cell and improve the connection between the solder ribbon and the solar cell.

[0094] To ensure compatibility with the layout and feeding of 0BB (no grid) battery strings that require adhesive application, such as... Figures 2 to 3 As shown, optionally, the battery string feeding device in this embodiment of the application further includes a glue application mechanism 7.

[0095] When it is necessary to feed the OBB battery string, the first conveying mechanism 4 picks up the battery string from the first conveyor line 3 and does not flip the battery string. Instead, it directly transports the battery string to the gluing mechanism 7 with the front side facing up.

[0096] The adhesive application mechanism 7 completes the adhesive application to the front of the battery string, and after flipping the battery string with the back side facing up, it applies adhesive to the back side of the battery string.

[0097] Subsequently, the second transport mechanism 5 picks up the glued battery strings with their backs facing up from the glue application mechanism 7 and transports them to the loading transition section 6. In this way, during layout, the layout picking mechanism can pick up the glued battery strings with their backs facing up from the loading transition section 6 and perform layout of the battery strings.

[0098] As can be seen, by setting up the gluing mechanism 7, on the one hand, continuous gluing is achieved on both surfaces of the battery string, making the battery string feeding device of this application compatible with the layout and feeding of gridless battery strings that require gluing. On the other hand, the battery string is flipped so that the battery string is placed on the feeding transition part 6 with its back facing up, which meets the layout requirements.

[0099] Optionally, the first conveying mechanism 4 includes a first translation drive unit, a first lifting drive unit, a first flipping drive unit, and a first adsorption unit, wherein: the first lifting drive unit is connected to a movable component of the first translation drive unit, the first flipping drive unit is connected to a movable component of the first lifting drive unit, and the first adsorption unit is connected to a movable component of the first flipping drive unit. The first translation drive unit is used to drive the first adsorption unit to translate along a second horizontal direction (such as the Y-axis direction), the first lifting drive unit is used to drive the first adsorption unit to rise and fall, the first flipping drive unit is used to drive the first adsorption unit to flip, and the first adsorption unit 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 adhesive application, the first adsorption unit can pick up the battery string from the first conveyor line 3 through the coordinated drive of the first translation drive unit, the first lifting drive unit and the first flipping drive unit, and flip the picked-up battery string to face up. The battery string flipped to face up is finally transported to the loading transition unit 6 by the second conveying mechanism 5.

[0101] For gridless battery strings that require adhesive application, the first adsorption unit picks up the battery string from the first conveyor line 3 through the cooperation of the first translation drive unit and the first lifting drive unit, and then transports the picked-up battery string to the adhesive application mechanism 7. The adhesive application mechanism 7 flips the battery string during the adhesive application process so that the back of the battery string faces up. The battery string with the back facing up after adhesive application is finally transported to the feeding transition unit 6 by the second conveying mechanism 5.

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

[0103] The first flipping drive unit can be any existing flipping drive module capable of driving the first adsorption unit to flip, such as a flipping drive module consisting of a rotary drive motor, a rotating shaft and a flipping plate.

[0104] Optionally, the first adsorption unit includes a mounting bracket and a plurality of suction cups arranged along a first horizontal direction on the mounting bracket, the plurality of suction cups working together to pick up battery strings from the first conveyor line 3.

[0105] like Figures 5 to 7As shown, optionally, the second conveying mechanism 5 includes a second lifting drive unit 51, a rotary drive unit 52, a rotating shaft 53, a second suction unit 54, and two swing arms 55. The rotary drive unit 52 is connected to the movable part of the second lifting drive unit 51, and the rotating shaft 53 is connected to the movable part of the rotary drive unit 52 and extends along a first horizontal direction. The upper ends of both swing arms 55 are fixedly connected to the rotating shaft 53. The second suction unit 54 is disposed between the two swing arms 55 along the first horizontal direction, and the lower ends of the two swing arms 55 are rotatably connected to both ends of the second suction unit 54.

[0106] The rotary drive unit 51 is configured to drive two swing arms 55 to swing via a rotating shaft 53, thereby moving the second adsorption unit 54 between the first conveying mechanism 4 and the loading transition unit 6. Alternatively, the rotary drive unit 51 is configured to drive two swing arms 55 to swing via a rotating shaft 53, thereby moving the second adsorption unit 54 between the loading transition unit 6 and the adhesive application mechanism 7. The second lifting drive unit 51 is configured to drive the second adsorption unit 54 to lift.

[0107] For battery strings that do not require adhesive application, the second conveying mechanism 5 needs to pick up the flipped battery strings from the first conveying mechanism 4, and then transport the picked-up battery strings to the loading transition section 6. The specific process is as follows:

[0108] First, the rotary 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 conveying mechanism 4.

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

[0110] Next, 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 unit 6.

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

[0112] For gridless battery strings that require adhesive application, the second conveying mechanism 5 needs to pick up the flipped battery strings from the adhesive application mechanism 7, and then transport the picked-up battery strings to the loading transition section 6. The specific process is as follows:

[0113] First, the rotary 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 glue application mechanism 7.

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

[0115] Next, 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 unit 6.

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

[0117] To improve the stability of the lifting and lowering of the second adsorption section 54, optionally, such as Figure 6 As shown, the second lifting drive unit 51 includes two lifting drive modules spaced apart along a first horizontal direction. A rotary drive unit 52 is mounted on a movable component of one of the lifting drive modules. The first end of a rotating shaft 53 is drive-connected to the movable component of the rotary drive unit 52, and the second end of the rotating shaft 53 is rotatably connected to the movable component of the other lifting drive module. The rotary drive unit 52 can employ various existing rotary drive modules capable of driving the rotating shaft 53 to rotate, such as a rotary motor.

[0118] Optionally, the second adsorption unit 54 includes a mounting beam 541 and a plurality of suction cup assemblies 542, wherein the two ends of the mounting beam 541 are rotatably connected to the lower end of one of the swing arms 55, and the plurality of suction cup assemblies 542 are spaced apart on the mounting beam 541 along the length direction (i.e., the first horizontal direction).

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

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

[0121] In this way, it can be ensured that after the second adsorption unit 54 moves into place, it can stably pick up the battery string on the first conveying mechanism 4 or the glue application mechanism 7 in a horizontal state, and that the second adsorption unit 54 can smoothly place the picked-up battery string onto the loading transition unit 6 in a horizontal state.

[0122] Optionally, connector 562 is a cylinder. For example... Figure 7 As shown, the cylinder body is hinged to the fixed frame 561, and the cylinder's telescopic rod is hinged to the first end of the connecting rod 563. By using a cylinder as a connecting member 562, the extension length of the cylinder's telescopic rod remains unchanged during the swinging process of the second adsorption part 54, thereby ensuring that the second adsorption part 54 always remains horizontal during the swinging process.

[0123] When the second adsorption part 54 swings to a predetermined position, such as when it swings to a predetermined manual inspection station, the cylinder can control the extension and retraction of the telescopic rod, thereby driving the second adsorption part 54 to flip outward from a horizontal state to a vertical state, so as to facilitate the inspection of the battery string adsorbed on the second adsorption part 54.

[0124] Of course, if it is not necessary to implement the flipping drive of the second adsorption part 54, an ordinary connecting rod can be used as the connector 562.

[0125] like Figure 4 As shown, in one optional embodiment, a conveyor belt is used as the loading transition section 6. The conveyor belt is used to transport battery strings along a second horizontal direction, which is perpendicular to the first horizontal direction. The width of the conveying surface of the loading transition section 6 along the first horizontal direction (e.g., the X-axis direction) is at least equal to the length of one battery string, and the conveying surface of the loading transition section 6 along the second horizontal direction (e.g., the Y-axis direction) can carry at least two battery strings. When the second conveying mechanism 5 transports the battery strings to the loading end of the loading transition section 6, the loading transition section 6 transports the battery strings along the second horizontal direction to the unloading end, and the subsequent layout and picking mechanism picks up the battery strings from the unloading end of the loading transition section 6.

[0126] A conveyor belt is used as the feeding transition section 6, which can carry at least two battery strings along the second horizontal direction, thus buffering the battery strings and enabling the subsequent layout and picking mechanism to promptly retrieve battery strings from the feeding transition section 6, preventing feeding delays. Furthermore, the layout and picking mechanism picks up battery strings from the unloading end of the feeding transition section 6 each time, simplifying the movement control strategy of the layout and picking mechanism.

[0127] Of course, if the feeding transition section 6 is not required to buffer the battery strings, a support platform can be used as the feeding transition section 6. Using a support platform as the feeding transition section 6 can reduce the installation space occupied by the feeding transition section 6. Thus, a storage box can be set on the side of the feeding transition section 6 to facilitate the recycling of defective battery strings into the storage box, or to buffer battery strings that the layout and picking mechanism cannot pick up in time into the storage box.

[0128] Optionally, the battery string feeding device in this embodiment further includes a detection mechanism, which is disposed on the moving path of the second conveying mechanism 5. The second conveying mechanism 5 is further configured to transport the picked-up battery strings with their backs facing up to the detection mechanism, which is configured to perform quality inspection on the battery strings. The second conveying mechanism 5 then transports the qualified battery strings to the loading transition section 6.

[0129] By setting up an inspection mechanism, before the battery strings are transported to the loading transition section 6, the second transport mechanism 5 first transports the picked-up battery strings with their backs facing up to the inspection mechanism, where the inspection mechanism performs quality inspection on the battery strings. The second transport mechanism 5 only transports the qualified battery strings to the loading transition section 6 to prevent unqualified battery strings with quality defects from flowing into the subsequent layout station.

[0130] Optionally, the second handling mechanism 5 places the defective battery strings at the recycling location.

[0131] When the loading transition section 6 occupies a large installation space, for example, when the loading transition section 6 uses a conveyor belt capable of buffering battery strings, if a fixed-position NG (Not From Good) material box is installed on the side of the loading transition section 6, the NG material box will inevitably interfere with the handling of the second conveying mechanism 5. To solve this problem, optionally, the battery string feeding device in this embodiment of the application further includes a telescopic drive mechanism. Figure 4 As shown, the telescopic drive mechanism is located below the feeding transition section 6. The telescopic drive 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) so as to drive the NG material box 110 to switch between the receiving position located outside the feeding transition section 6 and the avoidance position located below the feeding transition section 6.

[0132] Specifically, when the battery string on the second conveying mechanism 5 is determined to be a defective battery string after inspection, the telescopic drive mechanism drives the NG material box 110 to switch to the receiving position located outside the loading transition section 6. The second conveying mechanism 5 places the defective battery string into the NG material box 110 to implement the recycling and buffering of the defective battery string. After receiving the defective battery string, the telescopic drive mechanism drives the NG material box 110 to retract back to the avoidance position below the loading transition section 6.

[0133] As can be seen, by setting a telescopic drive mechanism below the feeding transition section 6 and placing the NG material box 110 on the moving part of the telescopic drive mechanism, the recycling of unqualified battery strings is achieved without interfering with the normal handling of the second handling mechanism 5.

[0134] When the loading transition section 6 occupies a small installation space, for example, when the loading transition section 6 uses a support platform that can only hold one battery string, there is sufficient installation space on the side of the loading transition section 6. Therefore, a storage box can be directly installed on the side of the loading transition section 6 to avoid the transport path of the second transport mechanism 5. The second transport mechanism 5 can place defective battery strings into the storage box. In addition, when the support platform already holds qualified battery strings, the second transport mechanism 5 can also buffer the qualified battery strings in the storage box.

[0135] like Figure 4 and Figure 6 As shown, optionally, the inspection mechanism includes an EL inspection camera 8, and a power-on component 9 is provided on the second transport mechanism 5. The power-on component 9 is configured to power the battery string on the second transport mechanism 5. The EL inspection camera 8 is configured to acquire infrared images of the battery string in the powered state to perform quality inspection of the battery string.

[0136] The EL inspection camera 8 and the power-on component 9 work together to perform quality inspection on the battery strings, ensuring that only qualified battery strings proceed to the subsequent layout stage. Furthermore, the power-on component 9 is mounted on the second transport mechanism 5, while the EL inspection camera 8 is located at the inspection station. Therefore, the second transport mechanism 5 can complete the inspection of the battery strings during transport, eliminating the need to transfer them to an additional inspection table. This improves inspection efficiency and avoids the additional handling of the battery strings during inspection, thus reducing the breakage rate of the battery cells.

[0137] Optionally, the power-conducting assembly 9 includes a first clamping member 91 and a second clamping member 92, wherein: the first clamping member 91 is disposed at the first end of the second conveying mechanism 5, the first clamping member 91 is electrically connected to the positive terminal of the power supply, and the first clamping member 91 is configured to clamp the extended solder strip at the first end of the battery string. The second clamping member 92 is disposed at the second end of the second conveying mechanism 5, the second clamping member 92 is electrically connected to the negative terminal of the power supply, and the second clamping member 92 is configured to clamp the extended solder strip at the second end of the battery string.

[0138] When the first clamping member 91 and the second clamping member 92 simultaneously clamp the extended solder strips at both ends of the battery string, the power supply can energize the battery string.

[0139] like Figure 4As shown, optionally, the adhesive application mechanism 7 includes a first adhesive application conveyor line 71, a first adhesive application section 72, a flipping conveyor section, a second adhesive application conveyor line 73, and a second adhesive application section 74. The first adhesive application conveyor line 71 is configured to receive battery strings transported by the first conveying mechanism 4 and sequentially convey the battery strings to a first adhesive application station A and a transfer station B along a first horizontal direction. The first adhesive application section 72 is located at the first adhesive application station A and above the first adhesive application conveyor line 71, and is configured to apply adhesive to the front side of the battery strings. The flipping conveyor section is located at the transfer station B, and is configured to pick up the battery strings at the transfer station B that have completed front-side adhesive application, flip the battery strings to their back-side up, and then convey the battery strings to the second adhesive application conveyor line 73. The second adhesive application conveyor line 73 is configured to sequentially convey battery strings to the second adhesive application station C and the unloading station D along the first horizontal direction. A second adhesive application unit 74 is located at the second adhesive application station C and above the second adhesive application conveyor line 73. The second adhesive application unit 74 is configured to apply adhesive to the back of the battery strings. The second conveying mechanism 5 picks up the adhesive-coated, back-side-up battery strings from the unloading station D of the second adhesive application conveyor line 73 and transports the picked-up, back-side-up battery strings to the loading transition unit 6.

[0140] As can be seen, after the first conveying mechanism 4 transports the battery string with its front side facing up to the first adhesive conveying line 71, the battery string completes front adhesive application on the first adhesive conveying line 71. The flipping conveyor flips the battery string and transports the flipped battery string to the second adhesive conveying line 73, which then transports the flipped battery string to the second adhesive station for back adhesive application.

[0141] Through the cooperation of the first glue application conveyor line 71, the first glue application section 72, the flipping conveyor section, the second glue application conveyor line 73, and the second glue application section 74, the glue application mechanism 7 realizes continuous glue application to both surfaces of the battery string, and flips the battery string during the glue application process so that the back of the battery string faces upwards to meet the layout requirements of the subsequent process.

[0142] The first adhesive application section 72 and the second adhesive application section 74 can be equipped with a screen printing device, which can accurately print the adhesive onto the solder ribbon, reducing the amount of adhesive used while ensuring the bonding effect on the solder ribbon. The first adhesive application section 72 and the second adhesive application section 74 can also be equipped with a dispensing device or an applicator.

[0143] like Figure 4As shown, optionally, the flipping conveyor includes a flipping section 75 and a conveying section 76, wherein: the conveying section 76 and the second adhesive application conveyor line 73 are both located above the first adhesive application conveyor line 71, and the conveying directions of the conveying section 76 and the second adhesive application conveyor line 73 are opposite to the conveying direction of the first adhesive application conveyor line 71; the output end of the conveying section 76 is connected to the input end of the second adhesive application conveyor line 73. The flipping section 75 is configured to pick up the battery string that has completed front-side adhesive application at the transfer station B, and flip the battery string so that its back side faces upwards. The flipping section 75 is also configured to transport the flipped battery string onto the conveying surface of the conveying section 76. The conveying section 76 is configured to convey the battery string onto the second adhesive application conveyor line 73.

[0144] As can be seen, after completing the flipping operation of the battery string, the flipping unit 75 directly places the battery string onto the conveying surface of the conveying unit 76. The conveying unit 76 then conveys the battery string to the second adhesive conveying line 73, which is connected to it. That is, during the process of transferring the flipped battery string from the first adhesive conveying line 71 to the second adhesive conveying line 73, there is no need to pick up the battery string, thereby reducing the risk of damage to the battery string.

[0145] In addition, the conveying section 76 and the second glue application conveying line 73 are arranged above the first glue application conveying line 71, and the conveying direction of the conveying section 76 and the second glue application conveying line 73 is set to be opposite to the conveying direction of the first glue application conveying line 71, thereby reducing the overall size of the glue application mechanism 7.

[0146] like Figures 9 to 11 As 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 assembly 755. The lifting frame 752 is connected to a movable part of the lifting drive unit 751. The flipping frame 753 is rotatably connected to the lifting frame 752 and is drively connected to the flipping drive unit 754 mounted on the lifting frame 752. The suction assembly 755 is mounted on the flipping frame 753. The lifting drive unit 751 is configured to drive the suction assembly 755 to descend, causing the suction assembly 755 to pick up battery strings from the transfer station B. The flipping drive unit 754 is configured to drive the suction assembly 755 to flip, causing the battery strings picked up on the suction assembly 755 to flip so that the back of the battery strings faces upwards. The lifting drive unit 751 is also configured to drive the suction assembly 755 to rise, placing the flipped battery strings onto the conveying surface of the conveying unit 76.

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

[0148] When the first adhesive conveyor line 71 transports the battery string that has completed front adhesive application to the transfer station B, the lifting drive unit 751 drives the suction component 755 to descend, so that the suction component 755 can absorb and pick up the battery string from the transfer station B.

[0149] Subsequently, the flipping drive unit 754 drives the suction component 755 to flip, thereby causing 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 above the conveying surface of the conveying section 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 section 76.

[0152] Optionally, the suction assembly 755 includes a plurality of suction cups spaced apart on the flipping frame 753 along a first horizontal direction, the plurality of suction cups being used to adsorb the battery string at the transfer station B.

[0153] Optionally, the suction components 755 are configured in two sets, namely a first suction component and a second suction component. The adsorption surfaces of the first and second suction components are opposite to each other. When the adsorption surface of the first suction component is flipped downwards, the adsorption surface of the second suction component is flipped upwards. In this way, the first and second suction components can alternately suction battery strings from the transfer station B and alternately flip the battery strings so that their backs are facing upwards before placing them on the conveying surface of the conveying section 76, thereby improving the efficiency of flipping and transferring the battery strings and ensuring the application cycle time of the second adhesive application section 74.

[0154] Continue to refer to Figures 9 to 11 As shown, optionally, the conveying unit 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 disposed 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 a second horizontal direction (such as the Y-axis direction), and are respectively drivenly connected to the opening and closing unit 762. 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 closer 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 mounted on the first connecting frame 763 along the first horizontal direction, and the second conveyor belt 766 is mounted 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 surfaces of the first conveyor belt 765 and the upper surfaces of the second conveyor belt 766 constitute the conveying surface of the conveying part 76.

[0156] The working process of the conveying unit 75 and the tilting unit 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, forming a lifting space with a first width between the first conveyor belt 765 and the second conveyor belt 766. 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 at this time, the battery string can pass upward through the lifting space and reach above the first conveyor belt 765 and the second conveyor belt 766.

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

[0160] Finally, the flipping section 75 descends through the lifting space. Since the width of the lifting space is smaller than the width of the battery string at this time, the two sides of the battery string are blocked by the first conveyor belt 765 and the second conveyor belt 766 respectively, and thus fall onto the first conveyor belt 765 and the second conveyor belt 766.

[0161] As can be seen, during the process of transferring the battery string from the flipping section 75 to the conveying section 76, there is no need to pick up the battery string, thereby preventing damage to the battery string.

[0162] The opening / closing unit 762 can employ various existing drive devices capable of driving the first connecting frame 763 and the second connecting frame 764 to slide towards the center or to the sides along the second horizontal direction. For example, the opening / closing unit 762 includes two linear drive modules with opposite driving directions mounted on the fixed frame 761. The two linear drive modules are respectively connected to the first connecting frame 763 and the second connecting frame 764. The two linear drive 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 drive modules can be, for example, cylinders, lead screw motors, etc.

[0163] This application also provides a typesetting device, such as Figure 2 and Figure 8 As shown, the typesetting device in this embodiment includes the battery string feeding device 10 and the typesetting picking mechanism 20 as described 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 in a mirror arrangement. The layout and picking mechanism 20 is located above the two feeding transition sections 6 and between the two second conveying mechanisms 5.

[0165] The layout 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 battery strings from one of the feeding transition parts 6 and arrange them, and the second picking part 220 is used to pick up battery strings from the other feeding transition part 6 and arrange them.

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

[0167] Continue to refer to Figure 8 As shown, optionally, the typesetting pickup mechanism 20 further includes a second translation drive unit 230, a spacing drive unit 240, a third lifting drive unit 250, and a fourth lifting drive unit 260, wherein: the spacing drive unit 240 is connected to the movable part of the second translation drive unit 230, the third lifting drive unit 250 and the fourth lifting drive unit 260 are connected to the movable part of the spacing drive unit 240, the first pickup unit 210 is connected to the movable part of the third lifting drive unit 250, and the second pickup unit 220 is connected to the movable part of the fourth lifting drive unit 260. The second translation drive unit 230 is used to drive the first pickup unit 210 and the second pickup unit 220 to translate synchronously along a first horizontal direction. The third lifting drive unit 250 is used to drive the first pickup unit 210 to lift, and the fourth lifting drive unit 260 is used to drive the second pickup unit 220 to lift. The separation drive unit 240 is used to drive the first pickup unit 210 and the second pickup unit 220 to translate in opposite directions along a second horizontal direction when they are at different heights, so that the first pickup unit 210 and the second pickup unit 220 move closer to the center or separate to both sides. The first pickup unit 210 and the second pickup unit 220 are also configured to drive the picked-up battery string to rotate in 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 sections 6, the third lifting drive section 250 and the fourth lifting drive section 260 first drive the first picking section 210 and the second picking section 220 to different heights. Subsequently, the splitting drive section 240 drives the first picking section 210 and the second picking section 220 to slide towards the middle along the second horizontal direction, so that the first picking section 210 and the second picking section 220 partially intersect.

[0170] Next, the second translation drive unit 230 drives the first pickup unit 210 and the second pickup unit 220 to move along the first horizontal direction toward the two loading transition units 6 until they reach above the two loading transition units 6. Since the first pickup unit 210 and the second pickup unit 220 partially intersect in the second horizontal direction, the first pickup unit 210 and the second pickup unit 220 will not come into contact with or interfere with the two second transport mechanisms 5 when they pass between them.

[0171] After the first pickup section 210 and the second pickup section 220 move into place toward the two feeding transition sections 6, the first pickup section 210 and the second pickup section 220 rotate synchronously to extend along the first horizontal direction, and the first pickup section 210 and the second pickup section 220 are respectively located above one of the feeding transition sections 6.

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

[0173] Next, the second translation drive unit 230 drives the first pickup unit 210 and the second pickup unit 220 to move away from the two loading transition units 6 along the first horizontal direction. After the first pickup unit 210 and the second pickup unit 220 pass between the two second conveying mechanisms 5, the first pickup unit 210 and the second pickup unit 220 rotate synchronously to extend along the second horizontal direction. Subsequently, the split drive unit 240 drives the first pickup unit 210 and the second pickup unit 220 to slide apart to both sides along the second horizontal direction, so that the two battery strings picked up by the first pickup unit 210 and the second pickup unit 220 are arranged at intervals along the second horizontal direction.

[0174] As can be seen, by configuring the layout and picking mechanism 20, it achieves simultaneous picking of two battery strings from the two feeding transition sections 6 and layout of the picked-up battery strings, thereby improving layout efficiency. Furthermore, since the first picking section 210 and the second picking section 220 of the layout and picking mechanism 20 can move closer together and partially overlap, even when the distance between the two second conveying mechanisms 5 is set to a small value, it can still be ensured that the first picking section 210 and the second picking section 220 of the layout and picking mechanism 20 can smoothly pass between the two second conveying mechanisms 5, thereby reducing the size and installation space of the battery string feeding device in this embodiment.

[0175] The second translation drive unit 230 can be any existing linear drive device capable of driving the pitch drive unit 240 to translate in the first horizontal direction. For example, the second translation drive unit 230 includes two synchronous belt drive modules spaced apart along the second horizontal direction. One end of the fixing component of the pitch drive unit 240 is connected to the drive end of one synchronous belt drive module, and the other end of the fixing component of the pitch drive unit 240 is connected to the drive end of another synchronous belt drive module. The two synchronous belt drive modules synchronously drive the pitch drive unit 240 to translate along the first horizontal direction.

[0176] Both the third lifting drive unit 250 and the fourth lifting drive unit 260 can adopt various existing linear drive modules that can drive the first pickup unit 210 and the second pickup unit 220 to lift, such as cylinder modules or lead screw motor modules.

[0177] Optionally, the first pickup unit 210 and the second pickup unit 220 have the same structure. Taking the first pickup unit 210 as an example, it includes a mounting bracket and a plurality of suction cups. The mounting bracket is connected to the drive end of the third lifting drive unit 250, and the plurality of suction cups are spaced apart on the mounting bracket along the length direction of the mounting bracket.

[0178] Optionally, the pitch drive unit 240 includes a timing belt drive assembly and a timing belt, wherein: the timing belt drive assembly is disposed on the movable part of the second translation drive unit 230, the timing belt is mounted on the timing belt drive assembly along the second horizontal direction, the fixing part of the third lifting drive unit 250 is fixedly connected to the first side of the timing belt, and the fixing part of the fourth lifting drive unit 260 is fixedly connected to the second side of the timing belt. The timing belt drive assembly is used to drive the timing belt to rotate, thereby causing the first pickup unit 210 and the second pickup unit 220 to move closer to the center or separate to both sides.

[0179] like Figures 2 to 4As shown, optionally, the layout device in this embodiment further includes a aligning conveyor mechanism 30, a welding pickup mechanism 40, and a welding mechanism 50, wherein: the layout pickup mechanism 20 is configured to pick up two battery strings from the output end of the feeding transition section 6 and place them onto the aligning conveyor mechanism 30 according to the layout positive and negative polarity requirements. The aligning conveyor mechanism 30 is configured to receive and align the battery strings placed by the layout pickup mechanism 20. The welding pickup mechanism 40 includes pickup components arranged one-to-one with each battery string in the battery string array. The aligning conveyor mechanism 30 is also configured to convey the aligned battery strings to the pickup station according to the layout position requirements. The welding pickup mechanism 40 moves to move the pickup component corresponding to the battery string at the pickup station to the pickup station to pick up the battery string. The welding pickup mechanism 40 moves to move the pickup component with the picked-up battery string to the welding station. The welding mechanism 50 welds a busbar onto the extended welding strip at the end of the battery string located at the welding station. The welding pickup mechanism 40 is also used to move after the busbar welding of the battery strings picked up by each pickup assembly is completed, so as to lay the battery strings picked up by each pickup assembly on the glass plate.

[0180] The layout and picking mechanism 20 picks up two battery strings from the feeding transition section 6 and places them onto the alignment and conveying mechanism 30 according to the positive and negative polarity requirements. The alignment and conveying mechanism 30 then aligns the battery strings according to the layout position requirements and conveys the aligned battery strings to the picking station. The welding picking mechanism 40 picks up the battery strings from the picking station and conveys them to the welding station. The welding mechanism 50 directly welds the busbars to the battery strings on the welding picking mechanism 40. After all the busbars are welded, the welding picking mechanism lays all the battery strings on the glass plate, thus completing the layout and busbar welding of a battery string array.

[0181] As can be seen, the layout equipment in this embodiment realizes automatic feeding, automatic layout and automatic welding of battery strings in sequence, without manual intervention, thereby greatly improving layout efficiency.

[0182] Optional, such as Figure 2 and Figure 3 As shown, the gluing mechanism 7 extends along the first horizontal direction and is located on both sides of the regularization conveying mechanism 30, the welding pick-up mechanism 40 and the welding mechanism 50, and will not increase the length of the typesetting equipment along the first horizontal direction in this embodiment of the application.

[0183] Optionally, the aligning and conveying mechanism 30 includes a first aligning and conveying section and a second aligning and conveying section with identical structures, arranged side by side along a second horizontal direction. The first aligning and conveying section and the second aligning and conveying section are respectively used to carry at least one battery string, for example, the first aligning and conveying section is used to carry the battery string released by the first pickup section 210, and the second aligning and conveying section is used to carry the battery string released by the second pickup section 220.

[0184] The first alignment and conveying section includes a translation drive and at least one alignment platform connected to the moving end of the translation drive. Each alignment platform is used to carry and align a string of batteries. The translation drive is used to drive the alignment platform to translate along a first horizontal direction to convey the battery strings on the alignment platform to a string picking station. Furthermore, the alignment platform is configured to rotate, thereby allowing for angle adjustment of the battery strings carried thereon.
