Description

Technical Field

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

[0002] When performing typesetting of battery strings, a battery string typesetting loading device is required to provide battery strings for the typesetting picking mechanism. Figure 1 As shown, the traditional battery string typesetting and loading device includes a string connection part 101, a string cutting part 102, a first conveyor line 103, a battery string handling mechanism 104, a second conveyor line 105 and a loading conveyor line 106, wherein the first conveyor line 103 is located at the rear of the string connection part 101, the string cutting part 102 is arranged between the output end of the string connection part 101 and the first conveyor line 103, the second conveyor line 105 is arranged side by side with the first conveyor line 103, and the output end of the second conveyor line 105 is connected to the input end of the loading conveyor line 106.

[0003] After the cells and solder ribbons with their first side (e.g., front side) facing upward are welded together on the stringing unit 101, they are cut into strings of predetermined lengths by the stringing unit 102 and flow onto the first conveyor line 103. The string transport mechanism 104 picks up the string from the first conveyor line 103, flips it 180°, and positions the second side (e.g., back side) facing upward before transporting it to the second conveyor line 105. The second conveyor line 105 then transports the string to the loading conveyor line 106, where the layout pick-up mechanism picks up the string and lays out the layout.

[0004] The overall length of the traditional battery string layout and loading device is long and occupies a large space. Utility Model Content

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

[0006] A battery string layout feeding device includes a string connection mechanism, a string cutter, a conveyor line, a first conveying mechanism, a second conveying mechanism and a first material box driving mechanism, wherein:

[0007] The conveyor line is located after the stringing mechanism, and the string cutter is located between the stringing mechanism and the conveyor line. After the first-side-up battery cells are connected into strings on the stringing mechanism through the welding ribbon, they are cut into battery strings of predetermined length by the string cutter and flow into the conveyor line.

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

[0009] The first material box driving mechanism is disposed above the conveyor line, and is used for carrying the first material box and driving the first material box to translate along a second horizontal direction, so as to drive the first material box to switch between a first material receiving position and a material loading position, wherein the second horizontal direction is perpendicular to the first horizontal direction;

[0010] The first transport mechanism is disposed between the conveyor line and the first magazine driving mechanism, and is configured to pick up a battery string from the conveyor line and flip the picked battery string so that the second side faces upward;

[0011] The second conveying mechanism is located above the first material box driving mechanism, and is configured to pick up the second battery string facing upward from the first conveying mechanism and place the battery string into the first material box switched to the first material receiving position.

[0012] The battery string typesetting and loading device provided in the present application has a first material box driving mechanism and a conveyor line arranged in layers above and below. After the battery strings cut by the string cutter flow into the conveyor line, the conveyor line conveys them to the bottom of the first material box driving mechanism; then, the first conveying mechanism flips the battery string over to face the second side upward; then, the second conveying mechanism conveys the battery string with the second side facing upward on the first conveying mechanism to the first material box located on the first material box driving mechanism. During typesetting, the typesetting picking mechanism can pick up the battery string from the first material box nearby and implement typesetting of the battery string.

[0013] Since the first material box driving mechanism carrying the first material box and the conveyor line are arranged in layers above and below, the length and occupied space of the battery string layout and loading device of the present application are greatly reduced compared with the traditional battery string layout and loading device.

[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 the movable part of the first translation drive unit, the first flipping drive unit is connected to the movable part of the first lifting drive unit, and the first adsorption unit is connected to the movable part of the first flipping drive unit; the first translation drive unit is used to drive the first adsorption unit to translate along the 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.

[0015] Through the coordinated driving of the first translation drive unit, the first lifting drive unit and the first flipping drive unit, the first adsorption unit can pick up the battery string from the conveyor line, and flip the picked battery string to face the second side upward, and finally be transported to the first material box by the second transport mechanism.

[0016] In some embodiments, the second transport mechanism includes a second lifting drive unit and a second adsorption unit, wherein: the second adsorption unit is connected to the movable component of the second lifting drive unit, the second lifting drive unit is used to drive the second adsorption unit to rise and fall, and the second adsorption unit is used to adsorb the battery string.

[0017] The second adsorption part is driven to rise and fall by the second lifting drive part, so that the second conveying mechanism can pick up the second battery string facing upward from the first conveying mechanism and place the battery string into the first material box switched to the first material receiving position.

[0018] In some embodiments, the battery string layout and loading device further includes a detection mechanism, which is disposed below the second conveying mechanism; the detection mechanism is configured to perform quality inspection on the battery strings picked up by the second conveying mechanism, and the second conveying mechanism places the battery strings that pass the inspection into the first material box.

[0019] By providing an inspection mechanism, the second transport mechanism can transport the picked-up battery strings with the second side facing upward to the inspection mechanism, which then performs a quality inspection on the battery strings. The second transport mechanism only transports battery strings that pass the inspection into the first magazine, preventing battery strings with quality defects from flowing into the subsequent typesetting station.

[0020] In some embodiments, the inspection mechanism includes an EL inspection camera, and the second transport mechanism is provided with a power-on component, which is configured to energize the battery string picked up by the second transport mechanism; the EL inspection camera is configured to obtain an infrared image of the battery string in the energized state to implement quality inspection of the battery string.

[0021] The EL inspection camera and the energized assembly work together to inspect the quality of the battery strings, ensuring that only qualified strings enter the subsequent layout station. Furthermore, the energized assembly is located on the second transport mechanism, and the EL inspection camera is located at the inspection station. This allows the second transport mechanism to inspect the battery strings during transport, eliminating the need to transfer the battery strings to a dedicated inspection table. This improves inspection efficiency and avoids the extra handling and placement of battery strings required for inspection, helping to reduce cell fragmentation.

[0022] In some embodiments, the power-on component includes a first clamp and a second clamp, wherein: the first clamp is arranged at the first end of the second conveying mechanism, the first clamp is electrically connected to the positive pole of the power supply, and the first clamp is configured to clamp the extended welding strip at the first end of the battery string; the second clamp is arranged at the second end of the second conveying mechanism, the second clamp is electrically connected to the negative pole of the power supply, and the second clamp is configured to clamp the extended welding strip at the second end of the battery string.

[0023] A power supply component with a simple structure is provided. After the second transport mechanism picks up the battery string, the first clamping member and the second clamping member respectively clamp the long welding strips at both ends of the battery string, and the power supply can be used to power the battery string through the first clamping member and the second clamping member.

[0024] In some embodiments, the battery string typesetting and loading device also includes a second material box driving mechanism arranged below the first material box driving mechanism; the second material box driving mechanism is used to carry the second material box and drive the second material box to move horizontally along the second horizontal direction to drive the second material box to switch between a second material receiving position and an avoidance position, and the second material receiving position is located directly below the first material receiving position; the second conveying mechanism is also configured to place the battery strings that fail the inspection into the second material box that has switched to the second material receiving position.

[0025] By arranging the second material box driving mechanism below the first material box driving mechanism, the second material box driving mechanism drives the second material box to switch between the second material receiving position and the avoidance position, which not only realizes the recovery and caching of unqualified battery strings, but also does not hinder the normal transportation of the second conveying mechanism.

[0026] The present application also provides a typesetting device, which includes two battery string typesetting loading devices and typesetting picking mechanisms as described in any one of the above items, wherein: the two battery string typesetting loading devices are arranged side by side and spaced apart along the second horizontal direction and are arranged in a mirror image; the typesetting picking mechanism is arranged above the two first material box driving 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 and typeset from the first material box switched to the loading position on one of the first material box driving mechanisms, and the second picking part is used to pick up the battery string and typeset from the first material box switched to the loading position on the other first material box driving mechanism.

[0027] Two battery string layout and loading devices are spaced side by side and arranged in a mirrored manner along the second horizontal direction. Therefore, the first magazines of the two battery string loading devices can simultaneously supply battery strings. The layout picking mechanism uses the first and second picking parts to synchronously pick up battery strings from the first magazines of the two battery string layout and loading devices and perform layout, thereby improving layout efficiency.

[0028] In some embodiments, the typesetting picking mechanism also includes a second translation drive unit, a third translation drive unit, a third lifting drive unit and a fourth lifting drive unit, wherein the third translation drive unit is connected to the movable part of the second translation drive unit, the third lifting drive unit and the fourth lifting drive unit are connected side by side on the movable part of the third translation drive unit along the second horizontal direction, the first picking part is connected to the movable part of the third lifting drive unit, and the second picking part is connected to the movable part of the fourth lifting drive unit; the second translation drive unit is used to drive the first picking part and the second picking part to translate along the first horizontal direction, the third translation drive unit is used to drive the first picking part and the second picking part to translate along the second horizontal direction, the third lifting drive unit is used to drive the first picking part to lift and lower, and the fourth lifting drive unit is used to drive the second picking part to lift and lower; the first picking part and the second picking part are also respectively configured to drive the picked-up battery string to rotate along the horizontal direction.

[0029] It can be seen that by setting up the typesetting picking mechanism, the first picking part and the second picking part of the typesetting picking mechanism can realize the synchronous picking of the battery strings in the first material box of the two battery string typesetting loading devices, and implement typesetting on the two picked battery strings, thereby improving the typesetting efficiency.

[0051] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] like Figures 2 to 3 As shown, the battery string typesetting and loading device 10 in the embodiment of the present application includes a string connection mechanism (not shown in the figure), a string cutter 1, a conveyor line 2, a first conveying mechanism 3, a second conveying mechanism 4 and a first material box driving mechanism 5, wherein:

[0053] The conveyor line 2 is located at the rear of the stringing mechanism, and the string cutter 1 is located between the stringing mechanism and the conveyor line 2. After the battery cells with the first side (for example, the front side) facing upward are connected into a string on the stringing mechanism through the welding ribbon, they are cut into battery strings of a predetermined length by the string cutter 1 and flow into the conveyor line 2.

[0054] The conveyor line 2 is configured to convey the battery strings along a first horizontal direction (eg, X direction).

[0055] The first material box driving mechanism 5 is arranged above the conveyor line 2. The first material box driving mechanism 5 is used to carry the first material box 100 and drive the first material box 100 to translate along the second horizontal direction (for example, the Y direction) to drive the first material box 100 to switch between the first material receiving position and the material loading position, wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0056] The first transport mechanism 3 is disposed between the conveyor line 2 and the first magazine driving mechanism 5 . The first transport mechanism 3 is configured to pick up a battery string from the conveyor line 2 and flip the picked battery string to have the second side (eg, the back side) facing upward.

[0057] The second conveying mechanism 4 is located above the first magazine driving mechanism 5 and is configured to pick up the second upward-facing battery string from the first conveying mechanism 3 and place the battery string into the first magazine 100 switched to the first receiving position.

[0058] The loading process of the battery string layout loading device in the embodiment of the present application is as follows:

[0059] After the battery cells and welding ribbons are welded into strings on the string connection mechanism, they are cut into battery strings by the string cutter 1 and flow into the conveyor line 2.

[0060] The conveyor line 2 conveys the battery string to the bottom of the first magazine driving mechanism 5 .

[0061] Subsequently, the first transport mechanism 3 picks up the battery string from the conveyor line 2 and turns the battery string over so that the second side faces upward.

[0062] Next, the second conveying mechanism 4 picks up the second battery string facing upward from the first conveying mechanism 3 and places the battery string into the first material box 100 located at the first material receiving position.

[0063] During layout, the layout picking mechanism can pick up the battery string with the second side facing upward from the first material box 100 switched to the loading position, and perform layout on the battery string.

[0064] Since the first material box driving mechanism 5 carrying the first material box 100 and the conveyor line 2 are arranged in layers above and below, the length and occupied space of the battery string layout and loading device in the embodiment of the present application are greatly reduced compared with the traditional battery string layout and loading device.

[0065] Optionally, the first material box driving mechanism 5 can adopt various existing linear driving modules that can drive the first material box 100 to translate along the second horizontal direction. For example, the first material box driving mechanism 5 is a synchronous belt driving module composed of components such as a motor, a synchronous belt and a synchronous pulley. The first material box 100 is connected to one side of the synchronous belt, and the motor drives the synchronous belt to transport along the second horizontal direction through the synchronous pulley, thereby driving the first material box 100 to translate along the second horizontal direction.

[0066] like Figure 4 As shown, optionally, the first transport mechanism 3 includes a first translation drive unit 31, a first lifting drive unit 32, a first flipping drive unit 33, and a first adsorption unit 34, wherein: the first lifting drive unit 32 is connected to the movable component of the first translation drive unit 31, the first flipping drive unit 33 is connected to the movable component of the first lifting drive unit 32, and the first adsorption unit 34 is connected to the movable component of the first flipping drive unit 33. The first translation drive unit 31 is used to drive the first adsorption unit 34 to translate along the second horizontal direction, the first lifting drive unit 32 is used to drive the first adsorption unit 34 to rise and fall, the first flipping drive unit 33 is used to drive the first adsorption unit 34 to flip, and the first adsorption unit 34 is used to adsorb the battery string.

[0067] Through the coordinated driving of the first translation drive unit 31, the first lifting drive unit 32 and the first flipping drive unit 33, the first adsorption unit 34 can pick up the battery string from the conveyor line 2, and flip the picked battery string to face the second side upward, and finally be transported to the first material box 100 by the second conveying mechanism 4.

[0068] The first translation drive unit 31 and the first lifting drive unit 32 can both adopt various existing linear drive modules that can drive the first adsorption unit 34 to translate and lift, such as a cylinder drive module or a screw motor drive module.

[0069] The first flip driving portion 33 may adopt various existing flip driving modules capable of driving the first adsorption portion 34 to flip, such as a flip driving module composed of a rotation driving motor, a rotating shaft, and a flip plate.

[0070] Optionally, the first adsorption portion 34 includes a mounting bracket and a plurality of suction cups arranged on the mounting bracket along a first horizontal direction, and the plurality of suction cups cooperate to absorb the battery string from the conveyor line 2 .

[0071] like Figure 5As shown, optionally, the second transport mechanism 4 includes a second lifting drive unit 41 and a second adsorption unit 42, wherein: the second adsorption unit 42 is connected to the movable part of the second lifting drive unit 41, the second lifting drive unit 41 is used to drive the second adsorption unit 42 to rise and fall, and the second adsorption unit 42 is used to adsorb the battery string.

[0072] The second transport mechanism 4 transports the battery string as follows:

[0073] First, the first magazine driving mechanism 5 drives the first magazine 100 to the loading position so that the second adsorption portion 42 and the first conveying mechanism 3 are not blocked by the first magazine 100 .

[0074] When the first transport mechanism 3 flips the battery string to face the second side upward, the second lifting drive 41 drives the second adsorption portion 42 downward until the second adsorption portion 42 adsorbs the battery string. The second lifting drive 41 then drives the second adsorption portion 42 upward to return to its original position.

[0075] Next, the first material box driving mechanism 5 drives the first material box 100 to the first material receiving position. At this time, the first material box 100 is located between the first conveying mechanism 3 and the second adsorption portion 42 .

[0076] Finally, the second lifting drive unit 41 drives the second adsorption unit 42 to descend to a predetermined height and then releases the battery string, so that the battery string falls into the first material box 100 .

[0077] Optionally, the battery string layout and loading device in the embodiment of the present application further includes a detection mechanism, which is disposed below the second conveying mechanism 4. The detection mechanism is configured to perform quality inspection on the battery strings picked up by the second conveying mechanism 4, and the second conveying mechanism 4 places the battery strings that pass the inspection into the first material box 100.

[0078] By providing an inspection mechanism, the second transport mechanism 4 can transport the picked-up battery strings with the second side facing upward to the inspection mechanism, which then performs a quality inspection on the battery strings. The second transport mechanism 4 only transports battery strings that have passed the inspection into the first material box 100, preventing battery strings with quality defects from flowing into the subsequent typesetting station.

[0079] like Figure 2 and Figure 5 As shown, the inspection mechanism optionally includes an EL inspection camera 6. The second transport mechanism 4 is provided with a power-on component 7, which is configured to energize the battery string picked up by the second transport mechanism 4. The EL inspection camera 6 is configured to capture infrared images of the battery string in the energized state to perform quality inspection on the battery string.

[0080] The EL inspection camera 6 and the energizing assembly 7 work together to inspect the quality of the battery strings, ensuring that only qualified battery strings enter the subsequent typesetting station. Furthermore, the energizing assembly 7 is located on the second transport mechanism 4, and the EL inspection camera 6 is located at the inspection station. Therefore, the second transport mechanism 4 can complete the inspection of the battery strings during the transport process, eliminating the need to transfer the battery strings to a dedicated inspection table. This improves inspection efficiency and avoids the additional handling of the battery strings during inspection, helping to reduce the fragmentation rate of the battery cells.

[0081] Optionally, the power supply assembly 7 includes a first clamping member 71 and a second clamping member 72, wherein: the first clamping member 71 is disposed at the first end of the second transport mechanism 4, the first clamping member 71 is electrically connected to the positive pole of the power source, and the first clamping member 71 is configured to clamp the extended solder strip at the first end of the battery string. The second clamping member 72 is disposed at the second end of the second transport mechanism 4, the second clamping member 72 is electrically connected to the negative pole of the power source, and the second clamping member 72 is configured to clamp the extended solder strip at the second end of the battery string.

[0082] When the first clamping member 71 and the second clamping member 72 simultaneously clamp the extended welding strips at both ends of the battery string, the power supply can energize the battery string.

[0083] like Figure 3 As shown, the battery string typesetting and loading device in the embodiment of the present application optionally further includes a second magazine drive mechanism 8 disposed below the first magazine drive mechanism 5. The second magazine drive mechanism 8 is used to carry the second magazine 200 and drive the second magazine 200 to translate along a second horizontal direction, thereby driving the second magazine 200 to switch between a second receiving position and a avoidance position. The second receiving position is located directly below the first receiving position. The second transport mechanism 4 is further configured to place battery strings that fail inspection into the second magazine that has switched to the second receiving position.

[0084] Initially, the second magazine 200 remains in a safe position, preventing it from obstructing the normal handling of the second conveying mechanism 4. When the second conveying mechanism 4 picks up a second, face-up battery string that has failed inspection, the first magazine drive mechanism 5 drives the first magazine 100 to the loading position, while the second magazine drive mechanism 8 drives the second magazine 200 to the second receiving position. Subsequently, the second conveying mechanism 4 descends and releases the failed battery string into the second magazine 200. Finally, the second magazine drive mechanism 8 drives the second magazine 200 back to the safe position, awaiting the next failed battery string.

[0085] The second material box driving mechanism 8 can adopt various existing linear driving modules that can drive the second material box 200 to move horizontally along the second horizontal direction. For example, the second material box driving mechanism 8 is a synchronous belt driving module composed of components such as a motor, a synchronous belt and a synchronous pulley. The second material box 200 is connected to one side of the synchronous belt. The motor drives the synchronous belt to transport along the second horizontal direction through the synchronous pulley, thereby driving the second material box 200 to move horizontally along the second horizontal direction.

[0086] This application also provides a typesetting device, such as Figure 1 and Figure 6 As shown, the typesetting device includes two battery string typesetting and loading devices 10 and a typesetting picking mechanism 20, wherein: the two battery string typesetting and loading devices 10 are arranged side by side and spaced apart along the second horizontal direction (for example, the Y direction) and are arranged in a mirror image. The typesetting picking mechanism 20 is arranged above the two first magazine drive mechanisms 5. The typesetting picking mechanism 20 includes a first picking portion 210 and a second picking portion 220. The first picking portion 210 is used to pick up the battery string from the first magazine 100 switched to the loading position on one of the first magazine drive mechanisms 5 and typesetting, and the second picking portion 220 is used to pick up the battery string from the first magazine 100 switched to the loading position on the other first magazine drive mechanism 5 and typesetting.

[0087] Because the two battery string layout and loading devices 10 are spaced apart and arranged side by side in a mirrored arrangement along the second horizontal direction, the first magazines 100 of the two battery string layout and loading devices 10 can synchronously supply battery strings. The layout and picking mechanism 20, via the first picking portion 210 and the second picking portion 220, synchronously picks battery strings from the first magazines 100 of the two battery string layout and loading devices 10 and performs layout, thereby improving layout efficiency.

[0088] Continue to refer Figure 6 As shown, optionally, the typesetting picking mechanism 20 also includes a second translation drive unit 230, a third translation drive unit 240, a third lifting drive unit 250 and a fourth lifting drive unit, wherein the third translation 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 are connected side by side along the second horizontal direction to the movable part of the third translation drive unit 240, the first picking unit 210 is connected to the movable part of the third lifting drive unit 250, and the second picking unit 220 is connected to the movable part of the fourth lifting drive unit.

[0089] The second translation drive unit 230 is used to drive the first and second picking units 210, 220 to translate along a first horizontal direction. The third translation drive unit 240 is used to drive the first and second picking units 210, 220 to translate along a second horizontal direction. The third lifting drive unit 250 is used to lift the first picking unit 210, and the fourth lifting drive unit is used to lift the second picking unit 220. The first and second picking units 210, 220 are also each configured to rotate the picked-up battery string along a horizontal direction.

[0090] By setting up the typesetting picking mechanism 20, the first picking part 210 and the second picking part 220 of the typesetting picking mechanism can realize the synchronous picking of the battery strings in the first material box 100 of the two battery string typesetting loading devices 10, and implement typesetting on the two picked battery strings, thereby improving the typesetting efficiency.

[0091] The second translation drive unit 230 and the third translation drive unit 240 can both adopt various existing linear drive devices that can drive the first picking unit 210 and the second picking unit 220 to translate along the first horizontal direction and along the second horizontal direction, such as a chain drive device composed of components such as a motor, a chain, a sprocket and a guide rail, or a synchronous belt drive device composed of components such as a motor, a synchronous belt, a pulley and a guide rail.

[0092] The third lifting drive unit 250 and the fourth lifting drive unit can both adopt various existing linear drive modules that can drive the first picking unit 210 and the second picking unit 220 to move up and down, such as a cylinder module or a screw motor module.

[0093] Optionally, the first pickup unit 210 and the second pickup unit 220 have the same structure. For example, the first pickup unit 210 includes a rotation drive unit, a mounting bracket, and a plurality of suction cups. The rotation drive unit is connected to the drive end of the third lift drive unit 250, the mounting bracket is connected to the movable component of the rotation drive unit, and the plurality of suction cups are spaced along the length of the mounting bracket. The plurality of suction cups cooperate to attract the battery string, and the rotation drive unit drives the mounting bracket to rotate in a horizontal plane, thereby driving the synchronous rotation of the battery string.

[0094] Optionally, the typesetting device in the embodiment of the present application further includes a regular conveying mechanism, a welding picking mechanism and a welding mechanism, wherein: the typesetting picking mechanism 20 is configured to place the two picked-up battery strings onto the regular conveying mechanism according to the typesetting positive and negative requirements. The regular conveying mechanism is configured to receive and regularize the battery strings placed by the typesetting picking mechanism. The welding picking mechanism includes a picking-up string assembly arranged in a one-to-one correspondence with each battery string in the battery string array. The regular conveying mechanism is also configured to convey the regular battery strings to the picking-up string station according to the typesetting position requirements, and the welding picking mechanism moves to drive the picking-up string assembly corresponding to the battery string at the picking-up string station to move to the picking-up string station to pick up the battery string. The welding picking mechanism moves to drive the picking-up string assembly with the picked-up battery string to the welding station, and 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 and lay the battery strings picked up by each string picking assembly on the glass plate after the busbar welding of the battery strings picked up by each string picking assembly is completed.

[0095] The layout picking mechanism 20 places the two battery strings picked up from the battery string layout loading mechanism 10 onto the regular conveying mechanism according to the layout positive and negative pole requirements. The regular conveying mechanism then regularizes the battery strings according to the layout position requirements and conveys the regularized battery strings to the string picking station. The welding picking mechanism picks up the battery strings from the string picking station and conveys the battery strings to the welding station. The welding mechanism directly welds the busbars to the battery strings on the welding picking mechanism. After all the busbars are welded, the welding picking mechanism places all the battery strings on the glass plate. At this point, the layout and busbar welding of a battery string array are completed.

[0096] It can be seen that the typesetting equipment of the present application realizes automatic loading, automatic typesetting and automatic welding of bus bars of battery strings in sequence without human intervention throughout the process, thereby greatly improving the typesetting efficiency.
