Description

A correction device and welding equipment Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a correction device and welding equipment. Background Technology

[0002] Shingled solar cells are a technology that involves slicing solar cells and then welding them into strings using a special conductive adhesive. The cells are connected in a stacked manner, with no metal grid lines on the surface and no gaps between cells. This fully utilizes the usable surface area of ​​the module, reduces line losses associated with traditional metal grid lines, and thus significantly improves the module's conversion efficiency.

[0003] Existing shingled cell welding machines use a straightening mechanism to straighten the long and short sides of the solar cells separately, and then use a welding mechanism to weld the solar cells. However, when straightening the solar cells, the existing straightening mechanism operates on the long and short sides separately, requiring multiple drive mechanisms to work together. This results in a complex structure, difficulty in debugging, and low straightening efficiency.

[0052] This application discloses a straightening device and welding equipment. The driving component can simultaneously drive the first straightening component, the second straightening component, and the third straightening component to perform operations. The straightening device has a relatively simple structure, is easy to debug, and has high straightening efficiency.

[0053] Example 1

[0054] Please refer to Figures 1 to 3, which are schematic diagrams of a correction device 100 provided in Embodiment 1 of this application. The correction device 100 includes a substrate 10, a first correction component 20, a second correction component 30, a third correction component 40, and a driving component 50. The substrate 10 is used to place the battery cell a. The substrate 10 has a first direction x and a second direction y in a horizontal plane, and the first direction x and the second direction y are different directions. The first correction component 20 is slidably disposed on the substrate 10 along the first direction x, the second correction component 30 is slidably disposed on the substrate 10 along the first direction x, and the third correction component 40 is slidably disposed on the substrate 10 along the first direction x. The second direction y is slidably disposed on the substrate 10. The driving component 50 is disposed on the substrate 10 and connected to the first correction component 20, the second correction component 30 and the third correction component 40. The driving component 50 is used to drive the first correction component 20 and the second correction component 30 to slide closer to each other along the first direction x and push the battery cell a, and the third correction component 40 to slide along the second direction y and push the battery cell a. The driving component 50 is also used to drive the first correction component 20 and the second correction component 30 to slide further away from each other along the first direction x and the third correction component 40 to slide further away from the battery cell a along the second direction y.

[0055] In this embodiment, when the battery cell a is placed on the substrate 10, the length direction of the battery cell a is the same as the second direction y, and the width direction of the battery cell a is the same as the first direction x. In some other embodiments, the orientation of the battery cell a when placed on the substrate 10 can be reversed. The horizontal plane refers to the surface perpendicular to the thickness direction of the substrate 10.

[0056] In this embodiment, a battery cell a is placed on a substrate 10. A first alignment component 20, a second alignment component 30, and a third alignment component 40 are slidably disposed on the substrate 10. The first and second alignment components 20 and 30 can slide closer to or further apart along a first direction x, while the third alignment component 40 can slide along a second direction y. Simultaneously, a driving component 50 is disposed on the substrate 10 and connected to the first, second, and third alignment components 20, 30, and 40, allowing the driving component 50 to simultaneously drive the first, second, and third alignment components 20 and 30 to slide relative to the substrate 10. Therefore, by driving the first and second alignment components 20 and 30 to slide closer together along the first direction x and push the battery cell a, while the third alignment component 40 slides along the second direction y to push the battery cell a, alignment of the battery cell a can be achieved. Furthermore, the drive component 50 can simultaneously drive the first correction component 20, the second correction component 30, and the third correction component 40 to perform operations. The correction device 100 has a relatively simple structure, is easy to debug, and has high correction efficiency.

[0057] Optionally, as shown in FIG1, the substrate 10 is provided with adsorption holes 10a, and the alignment device 100 further includes a vacuum generating component (not shown), which is connected to the adsorption holes 10a. The vacuum generating component is used to provide adsorption force to adsorb the battery cell a onto the substrate 10. In this way, the adsorption force provided by the vacuum generating component can act on the battery cell a through the adsorption holes 10a, thereby adsorbing the battery cell a onto the substrate 10 and fixing the battery cell a to the substrate 10.

[0058] Furthermore, the adsorption force provided by the vacuum generating component is adjustable. For example, when the solar cell a needs to be aligned by the movement of the alignment component, the adsorption force provided by the vacuum generating component can be relatively small, only used to prevent the solar cell a from falling off the substrate 10 without completely fixing it. However, after the solar cell a has been aligned by the movement of the alignment component, the adsorption force provided by the vacuum generating component can be relatively large, mainly used to completely fix the solar cell a relative to the substrate 10, preventing displacement after alignment that would affect subsequent processes (e.g., affecting welding accuracy).

[0059] In some embodiments, as shown in Figures 3 and 4, the drive assembly 50 includes a motor (not shown), a drive pulley 52, a plurality of driven pulleys (not shown), and a transmission belt 54. The motor is mounted on the base plate 10, the drive pulley 52 is connected to the motor, the plurality of driven pulleys are mounted on the base plate 10, and the transmission belt 54 is drivingly connected to the drive pulley 52 and the plurality of driven pulleys. The transmission belt 54 has at least a first segment 54a, a second segment 54b, and a third segment 54c. The first segment 54a and the second segment 54b extend along a first direction x and are spaced apart along a second direction y. The first segment 54a and the second segment 54b are respectively connected to a first correction assembly 20 and a second correction assembly 30. The third segment 54c extends along the second direction y and is connected to a third correction assembly 40. Thus, by driving the drive wheel 52 to rotate via the motor, the drive wheel 52 drives the transmission belt 54 and the driven wheel to rotate. The first alignment component 20, the second alignment component 30, and the third alignment component 40 connected to the transmission belt 54 can slide relative to the substrate 10 as the transmission belt 54 moves. Simultaneously, the first alignment component 20 and the second alignment component 30 are respectively connected to the first segment 54a and the second segment 54b. Since the first segment 54a and the second segment 54b extend along the first direction x and are spaced apart along the second direction y, both the first alignment component 20 and the second alignment component 30 slide along the first direction x in opposite directions, allowing them to move closer to or further away from each other depending on the direction of the motor's rotation. The third alignment component 40 is connected to the third segment 54c. Since the third segment 54c extends along the second direction y, the third alignment component 40 slides along the second direction y, and can move closer to or away from the battery cell a depending on the direction of the motor's rotation.

[0060] Optionally, the multiple driven pulleys include a first driven pulley 53a, a second driven pulley 53b, a third driven pulley 53c, and a fourth driven pulley 53d. The lines connecting the first driven pulley 53a, the second driven pulley 53b, the third driven pulley 53c, and the fourth driven pulley 53d form a rectangular distribution. The transmission belt 54 located between the first driven pulley 53a and the second driven pulley 53b is the first segment 54a, the transmission belt 54 located between the third driven pulley 53c and the fourth driven pulley 53d is the second segment 54b, and the transmission belt 54 located between the second driven pulley 53b and the third driven pulley 53c is the third segment 54c. In this way, by connecting the transmission belt 54 to the first driven pulley 53a, the second driven pulley 53b, the third driven pulley 53c, and the fourth driven pulley 53d, and using two adjacent driven pulleys as boundaries, the transmission belt 54 can be divided into multiple segments. Furthermore, the first driven wheel 53a, the second driven wheel 53b, the third driven wheel 53c and the fourth driven wheel 53d are arranged in a rectangular shape by connecting them in sequence. The first segment 54a and the second segment 54b can extend along the first direction x, and the first segment 54a and the second segment 54b are spaced apart along the second direction y, while the third segment 54c can extend along the second direction y.

[0061] In some embodiments, the motor is movably mounted relative to the base plate 10 along a first direction x. The alignment device 100 further includes an adjustment mechanism 60, which is disposed on the base plate 10 and connected to the motor. The adjustment mechanism 60 is used to drive the motor to move relative to the base plate 10 along the first direction x. Thus, by driving the motor to move relative to the base plate 10 along the first direction x via the adjustment mechanism 60, when the motor moves closer to the driven pulley along the first direction x, the transmission belt 54 loosens. When the motor moves away from the driven pulley along the first direction x, the transmission belt 54 tightens. In this way, the adjustment mechanism 60 can adjust the tension of the transmission belt 54 by adjusting the positions of the motor and the drive pulley 52 relative to the base plate 10.

[0062] For example, the adjustment mechanism 60 includes a base 61 and a movable member 62. The base 61 is disposed on the base plate 10, and the movable member 62 is movably disposed on the base 61 along a first direction x. The movable member 62 is connected to a motor. Thus, by pushing the movable member 62 towards the motor along the first direction x, the motor is pushed by the movable member 62 and moves away from the driven wheel along the first direction x, and the drive belt 54 becomes tighter. Conversely, by pushing the movable member 62 away from the motor along the first direction x, the motor is pulled by the movable member 62 and moves towards the driven wheel along the first direction x, and the drive belt 54 becomes looser.

[0063] Optionally, the movable member 62 can be a screw or bolt, and the base 61 is provided with a threaded hole. By engaging the threaded portion of the movable member 62 with the threaded hole, the movable member 62 can move relative to the base 61 in a first direction when rotating relative to the base 61.

[0064] In some embodiments, as shown in FIG5, the first alignment component 20 includes a first connector 21 and a first clamping member 22. The first clamping member 22 is connected to the first connector 21, and the first segment 54a is clamped between the first clamping member 22 and the first connector 21. In this way, by connecting the first clamping member 22 to the first connector 21, the first clamping member 22 can clamp the first segment 54a to the first connector 21, thereby achieving the connection between the first segment 54a and the first alignment component 20, which is relatively easy to assemble and disassemble.

[0065] For example, the first alignment component 20 includes a first slider 23, a first fixing member 24, and a first pusher 25. The first slider 23 is slidably disposed on the substrate 10 along a first direction x. The first fixing member 24 is disposed on the first slider 23. One end of the first pusher 25 is disposed on the first fixing member 24, and the other end of the first pusher 25 extends from the first fixing member 24 along a second direction y. Thus, by being slidably disposed on the substrate 10, the first slider 23 can slide relative to the substrate 10 under the drive of the driving component 50. At this time, the first slider 23 can drive the first fixing member 24 and the first pusher 25 to slide closer to or away from the second alignment component 30, thereby cooperating with the second alignment component 30 to push the aligned battery cell a. Furthermore, the first pusher 25 extends along the second direction y, and the length extension direction of the first pusher 25 matches the length direction of the battery cell a, thereby increasing the contact area when the first pusher 25 pushes the battery cell a, making the alignment action of the battery cell a more stable and reliable.

[0066] In some embodiments, as shown in FIG6, the second alignment component 30 includes a second connector 31 and a second clamping member 32. The second clamping member 32 is connected to the second connector 31, and the second segment 54b is clamped between the second clamping member 32 and the second connector 31. In this way, by connecting the second clamping member 32 to the second connector 31, the second clamping member 32 can clamp the second segment 54b to the second connector 31, thereby achieving the connection between the second segment 54b and the second alignment component 30, which is relatively easy to assemble and disassemble.

[0067] For example, the second alignment component 30 includes a second slider 33, a second fixing member 34, and a second pushing member 35. The second slider 33 is slidably disposed on the substrate 10 along the first direction x. The second fixing member 34 is disposed on the second slider 33. One end of the second pushing member 35 is disposed on the second fixing member 34, and the other end of the second pushing member 35 extends from the second fixing member 34 along the second direction y. Thus, by being slidably disposed on the substrate 10, the second slider 33 can slide relative to the substrate 10 under the drive of the driving component 50. At this time, the second slider 33 can drive the second fixing member 34 and the second pushing member 35 to slide closer to or away from the first alignment component 20, thereby cooperating with the first alignment component 20 to push the aligned battery cell a. Furthermore, the second pushing member 35 extends along the second direction y, and the length extension direction of the second pushing member 35 matches the length direction of the battery cell a, thereby increasing the contact area when the second pushing member 35 pushes the battery cell a, making the alignment action of the battery cell a more stable and reliable.

[0068] Optionally, as shown in Figure 1, there are multiple first fixing members 24 and multiple first pushing members 25. Multiple first fixing members 24 are spaced apart along the first direction x on the first sliding member 23. Multiple first pushing members 25 are respectively disposed one-to-one on the first fixing members 24. There are multiple second fixing members 34 and multiple second pushing members 35. Multiple second fixing members 34 are spaced apart along the first direction x on the second sliding member 33. Multiple second pushing members 35 are respectively disposed one-to-one on the second fixing members 34. Multiple first pushing members 25 and multiple second pushing members 35 are alternately distributed along the first direction x. In this way, by setting multiple first fixing members 24, first pushing members 25, second fixing members 34 and second pushing members 35, the multiple first pushing members 25 and multiple second pushing members 35 are alternately distributed along the first direction x. An adjacent first pushing member 25 and a second pushing member 35 form a group. A battery cell a can be placed at the position of the substrate 10 between each group of first pushing members 25 and second pushing members 35. Thus, when each group of first pushing members 25 and second pushing members 35 approaches each other, it can push the battery cell a to move and achieve alignment.

[0069] In other words, the first correction component 20 and the second correction component 30 in this embodiment can work together to simultaneously correct multiple battery cells a, resulting in high correction efficiency.

[0070] In some embodiments, as shown in FIG7, the third alignment component 40 includes a third connector 41 and a third clamping member 42. The third clamping member 42 is connected to the third connector 41, and the third segment 54c is clamped between the third clamping member 42 and the third connector 41. In this way, by connecting the third clamping member 42 to the third connector 41, the third clamping member 42 can clamp the third segment 54c to the third connector 41, thereby achieving the connection between the third segment 54c and the third alignment component 40, which is relatively easy to assemble and disassemble.

[0071] Optionally, the third alignment component 40 includes a third slider 43 and a third pusher 44. The third slider 43 is slidably disposed on the substrate 10 along the second direction y, and the third pusher 44 is disposed on the third slider 43, extending along the first direction x. Thus, by slidably disposing of the third slider 43 on the substrate 10, the third slider 43 can slide relative to the substrate 10 under the drive of the driving component 50. At this time, the third slider 43 can drive the third pusher 44 to slide closer to or away from the battery cell a, thereby pushing the aligned battery cell a when it approaches. Furthermore, the third pusher 44 extends along the first direction x, and the length extension direction of the third pusher 44 matches the width direction of the battery cell a, enabling the third pusher 44 to simultaneously push multiple battery cells a arranged along the first direction x for alignment, resulting in high alignment efficiency.

[0072] Optionally, the third pusher 44 is detachably disposed on the third slider 43 to adjust the relative position of the third pusher 44 and the third slider 43 along the second direction y. In this way, by adjusting the relative position of the third pusher 44 and the third slider 43 along the second direction y, battery cells a of different lengths can be matched. Furthermore, even when the sliding stroke of the third alignment component 40 is limited, the relative position of the third pusher 44 and the third slider 43 along the second direction y can be adjusted according to the different alignment positions of the battery cell a along the second direction y.

[0073] For example, the third pusher 44 is provided with an air outlet 44a, which is used to discharge air toward the battery cell a. In this way, the air discharged toward the battery cell a through the air outlet 44a acts on the battery cell a, causing dust and other impurities on the surface of the battery cell a to fall off, thereby cleaning the battery cell a and preventing impurities from being pressed between the alignment component and the battery cell a during the alignment operation, which could lead to damage to the battery cell a.

[0074] In some embodiments, referring again to FIG4, the correction device 100 further includes a first sliding mechanism 71, which is disposed on the substrate 10. The first correction component 20 is connected to the first sliding mechanism 71 and is slidably disposed relative to the substrate 10 along a first direction x. In this way, the first correction component 20 is connected to the substrate 10 through the first sliding mechanism 71, the first correction component 20 can slide relative to the substrate 10 along the first direction x, and the first sliding mechanism 71 can provide guidance and support for the sliding of the first correction component 20.

[0075] For example, the first sliding mechanism 71 includes a first slide rail 71a and a first slider 71b. The first slide rail 71a is disposed on the substrate 10 and extends along a first direction x. The first slider 71b is slidably connected to the first slide rail 71a, and the first alignment component 20 is connected to the first slider 71b. In this way, because the first slide rail 71a extends along the first direction x, the first slider 71b, which is slidably connected to the first slide rail 71a, can slide along the first direction x, thereby driving the first alignment component 20 to slide relative to the substrate 10 along the first direction x.

[0076] In some embodiments, the correction device 100 further includes a second sliding mechanism 72, which is disposed on the substrate 10. The second correction component 30 is connected to the second sliding mechanism 72 and is slidably disposed relative to the substrate 10 along a first direction x. In this way, the second correction component 30 is connected to the substrate 10 through the second sliding mechanism 72, the second correction component 30 can slide relative to the substrate 10 along the first direction x, and the second sliding mechanism 72 can provide guidance and support for the sliding of the second correction component 30.

[0077] For example, the second sliding mechanism 72 includes a second slide rail 72a and a second slider 72b. The second slide rail 72a is disposed on the substrate 10 and extends along a first direction x. The second slider 72b is slidably connected to the second slide rail 72a, and the second alignment component 30 is connected to the second slider 72b. Thus, by extending the second slide rail 72a along the first direction x, the second slider 72b, which is slidably connected to the second slide rail 72a, can slide along the first direction x, thereby driving the second alignment component 30 to slide relative to the substrate 10 along the second direction y.

[0078] In some embodiments, the correction device 100 further includes a third sliding mechanism 73, which is disposed on the substrate 10. The third correction component 40 is connected to the third sliding mechanism 73 and is slidably disposed relative to the substrate 10 along the second direction y. In this way, the third correction component 40 is connected to the substrate 10 through the third sliding mechanism 73, the third correction component 40 can slide relative to the substrate 10 along the second direction y, and the third sliding mechanism 73 can provide guidance and support for the sliding of the third correction component 40.

[0079] For example, the third sliding mechanism 73 includes a third slide rail 73a and a third slider 73b. The third slide rail 73a is disposed on the substrate 10 and extends along the second direction y. The third slider 73b is slidably connected to the third slide rail 73a, and the third alignment component 40 is connected to the third slider 73b. In this way, because the third slide rail 73a extends along the second direction y, the third slider 73b, which is slidably connected to the third slide rail 73a, can slide along the second direction y, thereby driving the third alignment component 40 to slide relative to the substrate 10 along the second direction y.

[0080] Embodiment 1 of this application provides a correction device 100. A battery cell a is placed on a substrate 10. A first correction component 20, a second correction component 30, and a third correction component 40 are slidably disposed on the substrate 10. The first and second correction components 20 and 30 can slide towards or away from each other along a first direction x, while the third correction component 40 can slide along a second direction y. Simultaneously, a driving component 50 is disposed on the substrate 10 and connected to the first, second, and third correction components 20, 30, and 40, allowing the driving component 50 to simultaneously drive the first, second, and third correction components 20 and 30 to slide relative to the substrate 10. Based on this, by driving the first and second correction components 20 and 30 to slide towards each other along the first direction x and push the battery cell a, while the third correction component 40 slides along the second direction y to push the battery cell a, the battery cell a can be corrected. Furthermore, the drive component 50 can simultaneously drive the first correction component 20, the second correction component 30, and the third correction component 40 to perform operations. The correction device 100 has a relatively simple structure, is easy to debug, and has high correction efficiency.
