[0031] Known technologies, methods, and devices for those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0032] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] According to an embodiment of the present application, a welding and handling device is provided. As Figures 1 to 6As shown, the welding and handling device includes a mounting mechanism 1 that is capable of moving between a first position 6 and a second position 7; a picking mechanism 2 mounted on the mounting mechanism 1, where the picking mechanism 2 is adapted to adsorb the battery cell 5; and a pressing mechanism 3 mounted on the mounting mechanism 1, with the pressing mechanism 3 located on one side of the picking mechanism 2. The pressing mechanism 3 includes pressing members 31 distributed in an array, and the pressing members 31 are adapted to press the welding tape 51 against the battery cell 5 at the second position 7.

[0035] In this example, the welding and handling device of the present application includes a mounting mechanism 1, a picking mechanism 2, and a pressing mechanism 3. The mounting mechanism 1 is capable of moving between a first position 6 and a second position 7. The picking mechanism 2 is connected to the mounting mechanism 1, and the picking mechanism 2 is adapted to adsorb the battery cell 5, that is, the picking mechanism 2 can adsorb the battery cell 5 at the first position 6. Through the mounting mechanism 1, the picking mechanism can be driven to move to the second position 7, and then the battery cell 5 is placed at the second position 7, so as to transport the battery cell 5 from the first position 6 to the second position 7. The pressing mechanism 3 is connected to the mounting mechanism 1, and the pressing mechanism 3 is adapted to press the welding tape 51 against the surface of the battery cell 5 at the second position 7 to facilitate welding the welding tape 51 to the battery cell 5. The welding and handling device of the present application can not only transport the battery cell 5 but also press the welding tape 51 against the battery cell 5 at the second position 7 to facilitate subsequent welding operations, increasing the functionality of the welding and handling device.

[0036] Moreover, both the pressing mechanism 3 and the picking mechanism 2 are mounted on the mounting mechanism 1, eliminating the need to install the pressing mechanism 3 at the second position 7, which is beneficial for saving space.

[0037] In this example, the mounting mechanism 1 can move between the first position 6 and the second position 7, thereby driving the picking mechanism 2 to move between the first position 6 and the second position 7. When the picking mechanism 2 moves to the first position 6, the picking mechanism 2 can adsorb the battery cell 5 at the first position 6; then, the mounting mechanism 1 drives the picking mechanism 2 to move to the second position 7, and the picking mechanism 2 places the battery cell 5 at the second position 7; finally, the pressing mechanism 3 can press the welding tape 51 against the battery cell 5 to facilitate subsequent welding processing of the battery cell 5 and the welding tape 51.

[0038] In this example, the welding tape 51 is bonded to the surface of the battery cell 5 through screen printing and dispensing 52. The first position 6 can be a placement platform for placing the battery cell 5 bonded with the welding tape 51. The second position 7 can be a welding platform for welding the welding tape 51 to the battery cell 5, and welding the welding tape 51 to the battery cell 5. As Figure 2As shown in the figure, taking the picking mechanism 2 on the right side as an example for illustration, the picking mechanism 2 is located on the right side of the pressing mechanism 3. After the picking mechanism 2 adsorbs the battery cell 5 on the placing platform at the first position 6, the installation mechanism 1 moves to the left to drive the picking mechanism 2 to move to the second position 7. The picking mechanism 2 places the battery cell 5 and the welding tape 51 on the welding platform at the second position 7. Then the installation mechanism 1 moves to the right to drive the pressing mechanism 3 to correspond to the welding tape 51 on the welding platform. The pressing mechanism 3 can press the welding tape 51 so that the welding tape 51 can closely adhere to the surface of the battery cell 5, thereby facilitating the welding of the welding tape 51 to the surface of the battery cell 5. The movement process of the picking mechanism 2 on the left side is similar to the movement mode of the picking mechanism 2 on the right side.

[0039] Alternatively, in this example, it is also possible that the picking mechanism 2 transports the battery cell 5 at the first position 6 to the second position 7, then places the welding tape 51 on the surface of the battery cell 5, and then the pressing mechanism 3 presses the welding tape 51 against the surface of the battery cell 5.

[0040] As Figures 2 to 5 shown, the pressing mechanism 3 includes pressing members 31 distributed in an array, and the pressing members 31 are adapted to press the welding tape 51 against the battery cell 5.

[0041] As Figure 3 and Figure 5 shown, in this example, the pressing mechanism 3 includes pressing members 31 distributed in an array, and the shape of the pressing members 31 distributed in an array can match the shape of the battery cell, so as to facilitate pressing the entire battery cell. For example, if the surface of the battery cell facing the pressing members 31 is rectangular, then the pressing members 31 distributed in an array form a rectangular structure.

[0042] A plurality of the pressing members 31 are adapted to press the welding tape 51 against the surface of the battery cell 5 so that the welding tape 51 can closely adhere to the surface of the battery cell 5.

[0043] As Figure 6 shown, in this example, a plurality of welding tapes 51 are bonded to the surface of the battery cell 5 through screen printing and dotting 52, and the plurality of welding tapes 51 are arranged at intervals. That is, screen printing and dotting 52 are provided on the surface of the battery cell 5, and the welding tape 51 is bonded to the battery cell 5 by means of heat curing or light curing. Each welding tape 51 is bonded by a plurality of spaced screen printing and dotting 52. The part of the welding tape between two adjacent screen printing and dotting 52 is used for welding with the surface of the battery cell 5. The pressing members 31 are distributed in an array so that each welding tape 51 can correspond to a plurality of pressing members 31 for pressing, so that more parts of the welding tape 51 can be fitted to the surface of the battery cell 5 to improve the reliability of welding.

[0044] In this example, the pressing members 31 are arranged at intervals, that is, there is a gap between two adjacent pressing members 31. This gap can avoid the position of the screen printing and dispensing 52, and can prevent the screen printing and dispensing 52 from being damaged by pressing.

[0045] In one example, as Figures 1 to 3 shown, the pressing mechanism 3 further includes a mounting plate 313, and a plurality of the pressing members 31 are connected to the mounting plate 313.

[0046] As Figure 3 shown, in this example, the pressing mechanism 3 further includes a mounting plate 313, and a plurality of pressing members 31 are connected to the mounting plate 313. During assembly, the plurality of pressing members 31 can be sequentially and fixedly installed on the mounting plate 313 first, and then the mounting plate 313 can be connected to the mounting mechanism 1 to improve the convenience of assembling the pressing members 31.

[0047] In this example, the pressing member 31 can be connected to the mounting plate 313 by means of screwing, clamping or welding, etc. Also, the mounting plate 313 can also be connected to the mounting mechanism 1 by means of screwing, clamping or welding, etc. Those skilled in the art can determine according to the actual situation and are not specifically limited herein.

[0048] In one example, as Figure 2 and Figure 3 shown, the pressing member 31 includes a pressing head 311 and a pressing rod 312. The pressing rod 312 is connected to the mounting mechanism 1, and the pressing head 311 is elastically telescopically connected to the pressing rod 312. The pressing head 311 is suitable for pressing the welding tape 51.

[0049] As Figure 3 shown, in this example, the pressing member 31 includes a pressing head 311 and a pressing rod 312. Among them, the pressing rod 312 can be connected to the mounting mechanism 1 or screwed to the mounting plate 313. The pressing head 311 is elastically telescopically connected to the pressing rod 312. When the pressing head 311 does not abut against the welding tape 51, the pressing head 311 is in a fully extended state. When the pressing head 311 presses the welding tape 51, the pressing head 311 can be in a compressed state.

[0050] By setting the pressing head 311 of the pressing member 31 as an elastically telescopic structure, when the pressing mechanism 3 moves downward to press the welding tape 51 and the pressing head 311 abuts against the welding tape 51, the pressing head 311 can contract appropriately, so as to play a buffering role and prevent the battery cell 5 or the welding tape 51 from being damaged. And when the surface of the battery cell 5 is not horizontal, the pressing head 311 with an elastically telescopic structure can improve the reliability of pressing the welding tape 51, thereby improving the welding yield.

[0051] In this example, a spring can be arranged inside the pressing member 31, that is, the pressing head 311 and the pressing rod 312 are slidably connected, and a spring is arranged between the pressing head 311 and the pressing rod 312. The spring is in a compressed state and has a tendency to push the pressing head 311 to move downward. Among them, a structure such as an anti - detachment buckle is also arranged between the pressing head 311 and the pressing rod 312 to limit the pressing head 311 to prevent the pressing head 311 from detaching from the pressing rod 312.

[0052] In one example, as Figure 1 shown, the welding and handling device further includes a fixed seat 4, and the installation mechanism 1 is movably connected to the fixed seat 4.

[0053] As Figure 1 described, in this example, the welding and handling device further includes a fixed seat 4, and the installation mechanism 1 is movably installed on the fixed seat 4. For example, a first slide rail 41 is arranged on the fixed seat 4, and the length direction of the first slide rail 41 is the direction from the first position 6 to the second position 7. For example, the first slide rail 41 can be horizontally arranged. The installation mechanism 1 is slidably installed on the first slide rail 41 and can slide along the slide rail.

[0054] In this example, the installation mechanism 1 can be driven to move along the first slide rail 41 by a linear motor, or the installation mechanism 1 can also be driven to move along the first slide rail 41 by a rotation motor cooperating with a lead screw structure. Or it can also be driven by other linear drive structures, which can be determined by those skilled in the art according to the actual situation and will not be specifically limited here.

[0055] In one example, as Figure 1 and Figure 2 shown, the installation mechanism 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is movably connected to the fixed seat 4, the second bracket 12 is movably connected to the first bracket 11, and the picking mechanism 2 and / or the pressing mechanism 3 are connected to the second bracket 12.

[0056] As Figure 2 shown, in this example, the installation mechanism 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 can be slidably installed on the first slide rail 41. The second bracket 12 is movably installed on the first bracket 11, and the second bracket 12 can move in the up - and - down direction.

[0057] In this example, the pressing mechanism 3 is connected to the second bracket 12. The second bracket 12 can move in the up and down direction, thereby driving the pressing mechanism 3 to move up and down. When the pressing mechanism 3 needs to press the welding tape 51, the second bracket 12 moves downward, so as to drive the pressing mechanism 3 to move downward, so that the pressing member 31 can press the welding tape 51 more stably. After the battery cell 5 and the welding tape 51 are processed, for example, after welding is completed, the second bracket 12 moves upward to drive the pressing mechanism 3 to move upward, so that the pressing member 31 disengages from the welding tape 51, so that the pressing member 31 can avoid the welding tape 51. That is, when the pressing mechanism 3 moves left and right, it can avoid the pressing member 31 colliding with the battery cell 5 or the welding tape 51, resulting in the displacement of the battery cell 5.

[0058] In this example, the picking mechanism 2 can also be connected to the second bracket 12. The second bracket 12 can move in the up and down direction, thereby driving the picking mechanism 2 to move up and down. When the picking mechanism 2 needs to adsorb the battery cell 5, the second bracket 12 moves downward, so as to drive the picking mechanism 2 to move downward, facilitating the picking mechanism 2 to adsorb the battery cell 5. After the battery cell 5 is placed at the second position 7, the second bracket 12 moves upward to drive the picking mechanism 2 to move upward, so that the picking mechanism 2 disengages from the battery cell 5, so that the picking mechanism 2 can avoid the battery cell 5. That is, when the picking mechanism 2 moves left and right, it can avoid the picking mechanism 2 colliding with the battery cell 5, resulting in the displacement of the battery cell 5.

[0059] In one example, as Figure 1 shown, the mounting mechanism 1 further includes a first sliding member 13, the fixed seat 4 is provided with a first sliding rail 41, and the first sliding member 13 is slidably connected to the first sliding rail 41.

[0060] The mounting mechanism 1 further includes a first sliding member 13. The first bracket 11 can be fixedly connected to the first sliding member 13, and the first sliding member 13 is slidably connected to the first sliding rail 41. Among them, the first sliding member 13 can be a structure such as a sliding plate or a sliding block. A sliding block is slidably arranged on the first sliding rail 41, and the first sliding member 13 can be a sliding block fixedly screwed to the first sliding rail 41.

[0061] In one example, the mounting mechanism 1 further includes a first driving member, and the first driving member is adapted to drive the second bracket 12 to move in the vertical direction.

[0062] In this example, the first bracket 11 is provided with a slide rail in the vertical direction, that is, in the up and down direction. The second bracket 12 is slidably connected to the slide rail of the first bracket 11. Among them, the first driving member can be a linear motor provided on the first bracket 11 to move the second bracket 12 up and down through the linear motor. Or the second bracket 12 can also be driven to move up and down by means of a rotating motor cooperating with a lead screw structure. Or it can also be driven by other linear driving structures, which can be determined by those skilled in the art according to the actual situation and will not be specifically limited herein.

[0063] In one example, as Figure 1 、 Figure 2 and Figure 5 shown, the picking mechanism 2 includes a second driving member 22 and a plurality of suction cups 21. The plurality of suction cups 21 are adapted to suck a plurality of the battery cells 5. The second driving member 22 is connected to the mounting mechanism 1, and the second driving member 22 is adapted to drive the suction cups 21 to move.

[0064] As Figure 1 described, in this example, the picking mechanism 2 includes a plurality of suction cups 21, such as vacuum suction cups 21, and the suction cups are evacuated by a vacuum generator. The suction cups 21 can suck a plurality of battery cells 5 to improve the conveying efficiency. For example, 10, 18, 20 or 24 suction cups 21 can be set, etc., which can be determined by those skilled in the art according to the actual situation and will not be specifically limited herein. Every two suction cups 21 can be in a group, and the two suction cups 21 can be connected by a connecting piece. A group of suction cups 21 can suck one battery cell 5 to ensure the stability of suction.

[0065] The battery cells 5 at the first position 6 can be sucked by the suction cups 21 and then placed at the second position 7. By sucking the battery cells 5 with the suction cups 21, it is possible to avoid damaging the battery cells 5 when adsorbing the battery cells 5.

[0066] As Figure 1 shown, in this example, the second driving member 22 is installed on the second bracket 12, and the second driving member 22 can drive the suction cups 21 to move up and down. The second driving member 22 can increase the moving stroke of the suction cups 21 by cooperating with the second bracket 12. When the suction cups 21 need to suck the battery cells 5, the second driving member 22 drives the suction cups 21 to move downward so as to facilitate the suction cups 21 to suck the battery cells 5. After the battery cells 5 are placed at the second position 7, the second driving member 22 drives the suction cups 21 to move upward so that the suction nozzles of the suction cups 21 are separated from the battery cells 5, so that the suction cups 21 can avoid the battery cells 5, that is, when the picking mechanism 2 moves left and right, it can avoid the suction cups 21 colliding with the battery cells 5 and causing the battery cells 5 to shift.

[0067] As Figure 1 and Figure 2As shown, in this example, there are multiple suction cups 21. Every two suction cups 21 can form a group, and the two suction cups 21 can be connected by a connecting piece. The middle position of the connecting piece is connected to the mounting rod 23. The output end of the second driving member 22 is connected to the mounting rod 23, so that a plurality of suction cups 21 can be driven to move up and down simultaneously by one second driving member 22, thereby reducing the driving cost.

[0068] Among them, the second driving member 22 can be a cylinder, or the second driving member 22 can also be a linear motor installed on the second bracket 12 to move the suction cup 21 up and down through the linear motor. Or the suction cup 21 can also be driven to move up and down by rotating the motor in cooperation with the lead screw structure. Or it can also be driven by other linear driving structures. Those skilled in the art can determine according to the actual situation and will not be specifically limited here.

[0069] As Figure 4 shown, in this example, the second bracket 12 is provided with a second slide rail 121 in the up and down direction, and the mounting rod 23 is also provided with a second slider 24. The second slider 24 is slidably connected to the second slide rail 121 of the second bracket 12 to improve the stability of the up and down sliding of the mounting rod 23. For example, the output end of the second driving member 22 is connected to the middle position of the mounting rod 23, and the second bracket 12 is provided with two second slide rails 121, and the two second slide rails 121 are respectively located on both sides of the second driving member 22.

[0070] In one example, the picking mechanism 2 is located on one side of the pressing mechanism 3, or the picking mechanism 2 is embedded in the pressing mechanism 3.

[0071] As Figure 2 shown, the picking mechanism 2 can be on the right side of the pressing mechanism 3. Or, the picking mechanism 2 can also be located on the left side of the pressing mechanism 3. So that the welding handling device of the present application can drive the picking mechanism 2 to convey the battery cell 5 through the movement of the mounting mechanism 1, and can also enable the pressing mechanism 3 to press the welding tape 51.

[0072] In this example, the picking mechanism 2 can also be embedded in the pressing mechanism 3, that is, there is an avoidance position in the pressing mechanism 3, and the picking mechanism 2 can be installed in the avoidance position, so that the overall structure of the welding handling device can be more compact to save space. For example, an avoidance hole is provided on the mounting plate 313 of the pressing mechanism 3, and the suction cup 21 of the picking mechanism 2 can pass through the avoidance hole. The suction cup 21 is driven by the second driving member 22 to move downward, so that the suction nozzle of the suction cup 21 protrudes from the pressing head 311 to suck the battery cell 5. The suction cup 21 is driven by the second driving member 22 to move upward to avoid the pressing head 311, so that the pressing head 311 can stably press the welding tape 51.

[0073] In one example, as Figure 1 andFigure 2 There are multiple installation mechanisms 1, and each installation mechanism 1 is connected to a picking mechanism 2 and a pressing mechanism 3.

[0074] As Figure 2 shown, in this example, by setting multiple installation mechanisms 1, picking mechanisms 2, and pressing mechanisms 3, solar cell wafers 5 of multiple processes can be conveyed. For example, two sets of installation mechanisms 1, picking mechanisms 2, and pressing mechanisms 3 are set. The two installation mechanisms 1 are respectively slidably connected to the fixed seat 4, and each installation mechanism 1 corresponds to a set of first positions 6, 6' and second positions 7, 7'.

[0075] According to another embodiment of the present application, a solar cell string welding machine is provided. The solar cell string welding machine includes a welding platform and the welding handling device of the above embodiment.

[0076] In this example, the solar cell string welding machine further includes a feeding device suitable for picking materials from a bin, a printing and gluing device suitable for screen-printing and dispensing glue 52 on the surface of the solar cell wafer 5. A first transfer mechanism is further provided between the printing and gluing device and the feeding device, and the first transfer mechanism is suitable for transferring the solar cell wafer 5 of the feeding device to the printing and gluing device. A solder tape processing device is located on one side of the printing and gluing device, and the solder tape processing device can cover the solar cell wafer 5 with surface-dispensed glue with a solder tape, and the solder tape corresponds to the dispensing position so that the solder tape can be bonded to the solar cell wafer 5 for subsequent welding. The welding platform is located on one side of the solder tape processing device, and the welding device is suitable for welding the solder tape to the solar cell wafer 5, that is, the welding platform can be the second position 7 of the above embodiment. A detection device is suitable for detecting the welded solar cell wafer 5.

[0077] Among them, after the solder tape 51 is bonded to the surface of the solar cell wafer 5, it is transported to the placement platform at the first position 6. The welding device includes a welding platform at the second position 7. The welding handling device of the present application can convey the solar cell wafer 5 with the bonded solder tape on the placement platform to the welding platform, and can press the solder tape on the welding platform against the surface of the solar cell wafer 5 through the pressing mechanism 3 for welding. The welding handling device of the present application can not only convey the solar cell wafer 5 but also press the solder tape 51 for subsequent operations, increasing the functionality of the welding handling device and being beneficial to saving the installation space of the solar cell string welding machine.

[0078] In this example, the solar cell string welding machine of the present application can weld the solder tape to the solar cell wafer 5 and connect multiple solar cell wafers in series for preparing a photovoltaic panel.

[0079] In the above embodiments, the differences between the embodiments are mainly described. As long as the different optimized features between the embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, it will not be elaborated here.
