Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a correction device and welding equipment. Background Art

[0002] The shingling technology is a technology that slices the cells and then welds them into strings with a special conductive adhesive material. The cells are connected by stacking them front and back, with no metal grid lines on the surface and no gaps between the cells. This fully utilizes the available area on the surface of the module and reduces the line loss of traditional metal grid lines, thus greatly improving the conversion efficiency of the module.

[0047] The utility model discloses a correction device and welding equipment. A driving component can simultaneously drive a first correction component, a second correction component and a third correction component to perform operations. The correction device has a simple structure, is easy to debug, and has a high correction efficiency.

[0048] Embodiment 1

[0049] Please also read Figures 1 to 3, is a structural schematic diagram of a correction device 100 provided in Embodiment 1 of the utility model, the correction device 100 comprises 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 second direction y is slidably arranged on the substrate 10, the driving component 50 is arranged on the substrate 10, the driving component 50 is connected to the first return component 20, the second return component 30 and the third return component 40, the driving component 50 is used to drive the first return component 20 and the second return component 30 to slide along the first direction x to approach each other and push the battery cell a, and the third return component 40 to slide along the second direction y to push the battery cell a, the driving component 50 is also used to drive the first return component 20 and the second return component 30 to slide along the first direction x to move away from each other, and the third return component 40 to slide along the second direction y away from the battery cell a.

[0050] 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 direction of the battery cell a when placed on the substrate 10 can be reversed. The horizontal plane refers to a surface perpendicular to the thickness direction of the substrate 10.

[0051] In this embodiment, the battery cell a is placed on the substrate 10, and the first correction component 20, the second correction component 30 and the third correction component 40 are slidably arranged by the substrate 10, and the first correction component 20 and the second correction component 30 can slide along the first direction x to approach or move away from each other, and the third correction component 40 can slide along the second direction y. At the same time, the driving component 50 is arranged on the substrate 10, and the driving component 50 is connected with the first correction component 20, the second correction component 30 and the third correction component 40, so that the driving component 50 can simultaneously drive the first correction component 20, the second correction component 30 and the third correction component 40 to slide relative to the substrate 10. Based on this, the driving component 50 drives the first correction component 20 and the second correction component 30 to slide along the first direction x to approach each other and push the battery cell a, and the third correction component 40 slides along the second direction y to push the battery cell a, so that the battery cell a can be corrected. Furthermore, the driving 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 a high correction efficiency.

[0052] Alternatively, if Figure 1As shown, the substrate 10 is provided with an adsorption hole 10a, and the correction device 100 further includes a vacuum generating assembly (not shown), which is connected to the adsorption hole 10a, and the vacuum generating assembly is used to provide an adsorption force to adsorb the battery cell a to the substrate 10. In this way, the vacuum generating assembly is used to provide an adsorption force, and the adsorption force can act on the battery cell a through the adsorption hole 10a, so that the battery cell a is adsorbed to the substrate 10, and the battery cell a and the substrate 10 are fixed.

[0053] Furthermore, the magnitude of the adsorption force provided by the vacuum generating assembly can be adjusted. For example, when the cell a needs to be corrected under the movement of the correcting assembly, the adsorption force provided by the vacuum generating assembly can be relatively small, which is only used to prevent the cell a from falling off from the substrate 10 without completely fixing it. When the cell a is corrected under the movement of the correcting assembly, the adsorption force provided by the vacuum generating assembly can be relatively large, which is mainly used to completely fix the cell a relative to the substrate 10, to prevent the cell a from shifting after correction and affecting the subsequent process (for example, affecting the welding accuracy).

[0054] In some embodiments, Figure 3 and Figure 4 As shown, the driving component 50 includes a motor (not shown), a driving wheel 52, a plurality of driven wheels (not marked) and a transmission belt 54. The motor is arranged on the substrate 10, the driving wheel 52 is connected to the motor, the plurality of driven wheels are arranged on the substrate 10, the transmission belt 54 is transmission-connected to the driving wheel 52 and the plurality of driven wheels, the transmission belt 54 has at least a first section 54a, a second section 54b and a third section 54c, the first section 54a and the second section 54b are extended along the first direction x, and the first section 54a and the second section 54b are spaced apart along the second direction y, the first section 54a and the second section 54b are respectively connected to the first alignment component 20 and the second alignment component 30, the third section 54c is extended along the second direction y, and the third section 54c is connected to the third alignment component 40. In this way, the driving wheel 52 is driven by the motor to rotate, and the driving wheel 52 drives the transmission belt 54 and the driven wheel to rotate, so that the first return component 20, the second return component 30 and the third return component 40 connected to the transmission belt 54 can slide relative to the substrate 10 with the movement of the transmission belt 54. At the same time, the first return component 20 and the second return component 30 are respectively connected to the first section 54a and the second section 54b. Since the first section 54a and the second section 54b extend along the first direction x and are arranged at intervals along the second direction y, the first return component 20 and the second return component 30 both slide along the first direction x, and the sliding directions are opposite, and they can approach or move away from each other according to the forward and reverse rotation of the motor. The third return component 40 is connected to the third section 54c. Since the third section 54c extends along the second direction y, the third return component 40 slides along the second direction y, and can slide close to and push the battery cell a or move away from the battery cell a according to the forward and reverse rotation of the motor.

[0055] Optionally, the plurality of driven wheels include a first driven wheel 53a, a second driven wheel 53b, a third driven wheel 53c and a fourth driven wheel 53d, and the lines connecting 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, the transmission belt 54 between the first driven wheel 53a and the second driven wheel 53b is the first section 54a, the transmission belt 54 between the third driven wheel 53c and the fourth driven wheel 53d is the second section 54b, and the transmission belt 54 between the second driven wheel 53b and the third driven wheel 53c is the third section 54c. In this way, by connecting the transmission belt 54 to the first driven wheel 53a, the second driven wheel 53b, the third driven wheel 53c and the fourth driven wheel 53d, the transmission belt 54 can be divided into multiple sections with two adjacent driven wheels as the boundary. Furthermore, by utilizing the sequential connecting lines of the first driven wheel 53a, the second driven wheel 53b, the third driven wheel 53c and the fourth driven wheel 53d to form a rectangular distribution, the first section 54a and the second section 54b can extend along the first direction x, and the first section 54a and the second section 54b are spaced apart along the second direction y, and the third section 54c can extend along the second direction y.

[0056] In some embodiments, the motor is movably arranged relative to the substrate 10 along the first direction x, and the correction device 100 further includes an adjustment mechanism 60, which is arranged on the substrate 10 and connected to the motor, and is used to drive the motor to move relative to the substrate 10 along the first direction x. In this way, the motor is driven to move relative to the substrate 10 along the first direction x by the adjustment mechanism 60, and when the motor moves closer to the driven wheel along the first direction x, the transmission belt 54 becomes loose. When the motor moves away from the driven wheel along the first direction x, the transmission belt 54 becomes tight. In this way, the adjustment mechanism 60 can adjust the tightness of the transmission belt 54 by adjusting the position of the motor and the driving wheel 52 relative to the substrate 10.

[0057] Exemplarily, the adjustment mechanism 60 includes a base 61 and a movable member 62, wherein the base 61 is disposed on the substrate 10, and the movable member 62 is movably disposed on the base 61 along the first direction x, and the movable member 62 is connected to the motor. Thus, by pushing the motor to move closer to 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 transmission belt 54 becomes tighter. By pushing the motor to move away from the motor along the first direction x, the motor is pulled by the movable member 62 and moves closer to the driven wheel along the first direction x, and the transmission belt 54 becomes looser.

[0058] Optionally, the movable member 62 may be a screw or a bolt, and the base 61 is provided with a threaded hole. By the threaded portion of the movable member 62 cooperating with the threaded hole, the movable member 62 can move relative to the base 61 along the first direction when rotating relative to the base 61.

[0059] In some embodiments, such as Figure 5 As shown, the first return assembly 20 includes a first connection member 21 and a first pressing member 22, the first pressing member 22 is connected to the first connection member 21, and the first section 54a is pressed between the first pressing member 22 and the first connection member 21. In this way, by connecting the first pressing member 22 to the first connection member 21, the first pressing member 22 can press the first section 54a to the first connection member 21, thereby realizing the connection between the first section 54a and the first return assembly 20, and the difficulty of disassembly and assembly is relatively low.

[0060] Exemplarily, the first correction component 20 includes a first sliding member 23, a first fixing member 24 and a first pushing member 25. The first sliding member 23 is slidably disposed on the substrate 10 along the first direction x, the first fixing member 24 is disposed on the first sliding member 23, one end of the first pushing member 25 is disposed on the first fixing member 24, and the other end of the first pushing member 25 is extended from the first fixing member 24 along the second direction y. In this way, the first sliding member 23 is slidably disposed on the substrate 10, and the first sliding member 23 can slide relative to the substrate 10 under the drive of the driving component 50. At this time, the first sliding member 23 can drive the first fixing member 24 and the first pushing member 25 to slide close to or away from the second correction component 30, so as to cooperate with the second correction component 30 to jointly push and correct the battery cell a. In addition, the first pushing member 25 is extended along the second direction y, and the length extension direction of the first pushing member 25 matches the length direction of the battery cell a, thereby increasing the contact area when the first pushing member 25 pushes the battery cell a, and the correction action of the battery cell a is more stable and reliable.

[0061] In some embodiments, such as Figure 6 As shown, the second return assembly 30 includes a second connection member 31 and a second pressing member 32, the second pressing member 32 is connected to the second connection member 31, and the second section 54b is pressed between the second pressing member 32 and the second connection member 31. In this way, by connecting the second pressing member 32 to the second connection member 31, the second pressing member 32 can press the second section 54b to the second connection member 31, thereby realizing the connection between the second section 54b and the second return assembly 30, and the difficulty of disassembly and assembly is relatively low.

[0062] Exemplarily, the second correction component 30 includes a second sliding member 33, a second fixing member 34 and a second pushing member 35. The second sliding member 33 is slidably disposed on the substrate 10 along the second direction y, the second fixing member 34 is disposed on the second sliding member 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 is extended from the second fixing member 34 along the second direction y. In this way, the second sliding member 33 is slidably disposed on the substrate 10, and the second sliding member 33 can slide relative to the substrate 10 under the drive of the driving component 50. At this time, the second sliding member 33 can drive the second fixing member 34 and the second pushing member 35 to slide close to or away from the first correction component 20, thereby cooperating with the first correction component 20 to jointly push and correct the battery cell a. In addition, the second pushing member 35 is extended 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, and the correction action of the battery cell a is more stable and reliable.

[0063] Optionally, combined Figure 1 As shown, there are multiple first fixing members 24 and multiple first pushing members 25, multiple first fixing members 24 are arranged on the first sliding member 23 at intervals along the first direction x, and multiple first pushing members 25 are arranged on the first fixing member 24 one by one. There are multiple second fixing members 34 and multiple second pushing members 35, multiple second fixing members 34 are arranged on the second sliding member 33 at intervals along the first direction x, and multiple second pushing members 35 are arranged on the second fixing member 34 one by one. The multiple first pushing members 25 and the multiple second pushing members 35 are alternately distributed along the first direction x. In this way, the first fixing member 24, the first pushing member 25, the second fixing member 34 and the second pushing member 35 are all arranged in plural, so that the multiple first pushing members 25 and the multiple second pushing members 35 are alternately distributed one by one along the first direction x, and an adjacent first pushing member 25 and a second pushing member 35 form a group, and 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, so that when each group of first pushing members 25 and second pushing members 35 approach each other, they can push the battery cell a to move and achieve correction.

[0064] That is to say, the first alignment component 20 and the second alignment component 30 of the present embodiment can cooperate to achieve alignment of multiple battery cells a at the same time, and the alignment efficiency is relatively high.

In this way, by connecting the third pressing member 42 to the third connection member 41, the third pressing member 42 can press the third section 54c to the third connection member 41, thereby realizing the connection between the third section 54c and the third return assembly 40, and the difficulty of disassembly and assembly is relatively low.

In addition, the third pushing member 44 is extended along the third direction, and the length extension direction of the third pushing member 44 matches the width direction of the battery cell a, so that the third pushing member 44 can simultaneously push multiple battery cells a arranged along the first direction x for correction, and the correction efficiency is high.

[0067] Optionally, the third pusher 44 can be detachably mounted on the third slide 43 to adjust the relative position of the third pusher 44 and the third slide 43 along the second direction y. In this way, by adjusting the relative position of the third pusher 44 and the third slide 43 along the second direction y, the battery cells a of different lengths can be matched. In addition, when the sliding stroke of the third alignment component 40 is limited, the relative position of the third pusher 44 and the third slide 43 along the second direction y can be adjusted according to the different alignment positions of the battery cells a along the second direction y.

[0068] Exemplarily, the third pusher 44 is provided with an air outlet 44a, and the air outlet 44a is used to discharge air toward the battery cell a.
