Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, specifically relating to a welding equipment for conductive sheets of battery cells. Background Technology

[0002] In the production of some battery cells, conductive metal sheets need to be soldered between the cell electrodes and the circuit board located at the cell head to achieve electrical connection between the positive and negative electrodes of the cell and the circuit board. In some production scenarios, due to a certain height difference between the cell electrodes and the circuit board, the conductive metal sheets need to be bent to accommodate this height difference.

[0003] However, existing automated welding equipment does not have a bending mechanism for conductive metal sheets. The conductive metal sheets can only be bent by other bending equipment before being transported to the automated welding equipment for welding. During transportation, the bending angle of the conductive metal sheets is prone to change, which means that the bending angle of the conductive metal sheets cannot be perfectly matched with the height difference between the cell electrodes and the circuit board during the subsequent welding process. This will have an adverse effect on the welding quality. At the same time, the cross-equipment transportation of bent conductive metal sheets will also prolong the welding operation cycle, thereby reducing the cell production efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example 1 refer to Figures 1 to 7The battery cell conductive sheet welding equipment provided in this embodiment includes a battery cell conveying mechanism 1, a battery cell positioning mechanism 2, a welding mechanism 3, a first feeding mechanism 4, and a second feeding mechanism 5. The battery cell positioning mechanism 2 and the welding mechanism 3 are sequentially arranged above the battery cell conveying mechanism 1 along the conveying direction of the battery cell conveying mechanism 1, and the first feeding mechanism 4 and the second feeding mechanism 5 are sequentially arranged on one side of the battery cell conveying mechanism 1 along the conveying direction of the battery cell conveying mechanism 1.

[0021] Both the first feeding mechanism 4 and the second feeding mechanism 5 are used for feeding conductive sheets. In some embodiments, the first feeding mechanism 4 and the second feeding mechanism 5 can be used for feeding the same conductive sheet or for feeding different conductive sheets. In this embodiment, the first feeding mechanism 4 is used for feeding the positive electrode conductive sheet, and the second feeding mechanism 5 is used for feeding the negative electrode conductive sheet. The conductive sheet in this embodiment is a nickel sheet.

[0022] During the welding operation, the battery cell is transported by the battery cell conveying mechanism 1. The battery cell first arrives at the battery cell positioning mechanism 2 for positioning of the target welding position, including positioning of the positive electrode post, the negative electrode pad, and the corresponding positive and negative electrode welding points on the battery cell protection board. Then, the battery cell conveying mechanism 1 continues to transport the battery cell to the positive electrode conductive sheet welding station. The first feeding mechanism 4 feeds the positive electrode conductive sheet onto the battery cell, and the welding mechanism 3 welds the two ends of the positive electrode conductive sheet to the corresponding welding points on the positive electrode post and the battery cell protection board, respectively. Next, the battery cell conveying mechanism 1 transports the battery cell to the negative electrode conductive sheet welding station. The second feeding mechanism 5 feeds the negative electrode conductive sheet onto the battery cell, and the welding mechanism 3 welds the two ends of the negative electrode conductive sheet to the corresponding welding points on the negative electrode pad and the battery cell protection board, respectively, thus completing the welding operation. Finally, the battery cell conveying mechanism 1 can transport the welded battery cell back to the conveying starting point, where it can be picked up manually or by a robot and then re-fed.

[0023] The first feeding mechanism 4 includes a first feeding component 41, a first bending component 42, and a first vision positioning component 43. The first feeding component 41 operates between the first bending component 42 and the cell conveying mechanism 1. The first vision positioning component 43 is located below the operating path of the first feeding component 41. The first bending component 42 is used to bend the positive electrode conductive sheet. In this embodiment, the first feeding component 41 is a feeding robot, and the first vision positioning component 43 is a positioning CCD. The positive electrode conductive sheet bent by the first bending component 42 can be directly fed onto the cell conveying mechanism 1 through the first feeding component 41. During the feeding process of the first feeding component 41, the first vision positioning component 43 can also perform precise visual positioning of the bent positive electrode conductive sheet, which can improve both production efficiency and welding quality.

[0024] In one embodiment, the first bending assembly 42 includes a positioning seat 421, a positioning push block 422, a bending pressure block 423, a first driving member 424 for driving the positioning push block 422 to move horizontally, a second driving member 425 for driving the bending pressure block 423 to move vertically, and a third driving member 426 for driving the bending pressure block 423 and the second driving member 425 to move horizontally. The positioning push block 422 is located on one side of the positioning seat 421, and the bending pressure block 423 is located above the positioning seat 421. The first driving member 424, the second driving member 425, and the third driving member 426 can all be drive motors or drive cylinders.

[0025] Driven by the first driving member 424, the positioning push block 422 can push the positive electrode conductive sheet to abut against the positioning seat 421 in the horizontal direction, thereby restricting the movement of the positive electrode conductive sheet in the horizontal direction; driven by the third driving member 426, the bending pressure block 423 can approach the positioning seat 421 in the horizontal direction, and then driven by the second driving member 425, the bending pressure block 423 moves downward in the vertical direction and presses against the upper surface of the positive electrode conductive sheet, so that the lower surface of the positive electrode conductive sheet is tightly abutted against the positioning seat 421, thereby realizing the bending of the positive electrode conductive sheet. It should be noted that the bending block 423 is a contour bending block, and the shape of its end face that contacts the positive electrode conductive sheet matches the target bending shape of the positive electrode conductive sheet. Similarly, the shape of the inner wall of the positioning seat 421 that contacts the positive electrode conductive sheet also matches the target bending shape of the positive electrode conductive sheet. Thus, when the bending block 423 is pressed against the positioning seat 421, the positive electrode conductive sheet can be bent to form the target bending shape.

[0026] In some embodiments, the positioning base 421 includes a fixed support platform 4211, a floating support platform 4212, and a limiting barrier 4213. The floating support platform 4212 is disposed adjacent to and close to the fixed support platform 4211. The floating support platform 4212 can sink under the action of external force. When it sinks into place, the shape formed by the combination of the top surface of the floating support platform 4212 and the top surface of the fixed support platform 4211 matches the target bending shape of the positive electrode conductive sheet. The limiting barrier 4213 is disposed on the outer periphery of the fixed support platform 4211 and the floating support platform 4212. The positioning push block 422 is used to push the conductive sheet against the limiting barrier 4213, and the bending pressure block 423 is used to press the conductive sheet tightly against the fixed support platform 4211 and the floating support platform 4212.

[0027] It should be noted that the contour of the side wall of the limiting barrier 4213 that contacts the positive conductive sheet matches the side contour of the positive conductive sheet, and the contour of the end face of the positioning push block 422 that contacts the positive conductive sheet matches the side contour of the positive conductive sheet. When the positioning push block 422 is pushed into place, the positioning push block 422 and the limiting barrier 4213 can completely surround all the sides of the positive conductive sheet.

[0028] In this embodiment, the positive electrode conductive sheet 100 includes a first end 101 and a second end 102 connected to the first end 101. The bending point of the positive electrode conductive sheet 100 is located at the connection between the first end 101 and the second end 102. The top surface of the fixed support platform 4211 consists of a plane and an inclined plane, with the inclined plane located on the side of the fixed support platform 4211 closer to the floating support platform 4212. Before the bending operation, the positive electrode conductive sheet 100 is in a plane state. The plane portion of the top surface of the fixed support platform 4211 is flush with the top surface of the floating support platform 4212. The first end 101 is located on the plane portion of the top surface of the fixed support platform 4211, and the second end 102 is located on the top surface of the floating support platform 4212. When the bending pressure block 423 is pressed down into place, the floating support platform 4212 sinks, causing the connection between the first end 101 and the second end 102 to adhere to the inclined portion of the top surface of the fixed support platform 4211 and form a bending structure, thereby completing the bending operation. By setting up a floating support platform 4212, the positive electrode conductive sheet 100 can be supported more comprehensively before bending operations, and the bending of the positive electrode conductive sheet 100 can be achieved, which can further improve the quality of welding operations.

[0029] As one way to achieve the up-and-down floating of the floating support platform 4212, the floating support platform 4212 may include a mounting plate 4214, a spring 4215 and a support block 4216. The spring 4215 is vertically mounted on the mounting plate 4214, and the top of the spring 4215 is connected to the support block 4216. Under the action of external force, the support block 4216 can compress the spring 4215 to sink. When the external force is released, the spring 4215 can naturally extend upward to reset the support block 4216. As a further optimization, a limiting groove 4217 can be opened on one side wall of the support block 4216, and a single-control cylinder 4218 can be set outside the limiting groove 4217. When the support block 4216 sinks into place, the telescopic rod of the single-control cylinder 4218 can be controlled to extend and lock into the limiting groove 4217, thereby fixing the position of the support block 4216 until the bent positive conductive sheet is removed, and then the limiting of the support block 4216 is released. This can prevent the premature reset of the support block 4216 from affecting the bending effect of the positive conductive sheet.

[0030] In some embodiments, the first feeding mechanism 4 further includes a first conductive sheet supply component 44 and a first transfer component 45, with the first transfer component 45 operating between the first conductive sheet supply component 44 and the first bending component 42. The first conductive sheet supply component 44 can be a feeder, and the first transfer component 45 can be a robotic arm.

[0031] The second feeding mechanism 5 includes a second conductive sheet supply assembly 51, a second transfer assembly 52, a second bending assembly 53, a second feeding assembly 54, and a second visual positioning assembly 55. The second transfer assembly 52 operates between the second conductive sheet supply assembly 51 and the second bending assembly 53. The second feeding assembly 54 operates between the second bending assembly 53 and the cell conveying mechanism 1. The second visual positioning assembly 55 is located below the operating path of the second feeding assembly 54. It should be noted that the structure of the second feeding mechanism 5 is the same as that of the first feeding mechanism 4. The specific structure can be set with reference to the first feeding mechanism 4, and will not be described in detail here.

[0032] Example 2 As a further optimization of Example 1, in Figures 1 to 7 Based on, refer to Figures 8 to 9 The battery cell conductive sheet welding equipment also includes a barcode scanning mechanism 6 disposed above the battery cell conveying mechanism 1. The barcode scanning mechanism 6 can scan and bind the battery cells of the battery cell conveying mechanism 1. The battery cell positioning mechanism 2 includes a height positioning component 21 and a plane positioning component 22. The barcode scanning mechanism 6, the height positioning component 21, and the plane positioning component 22 are arranged sequentially along the conveying direction of the battery cell conveying mechanism 1.

[0033] The height positioning component 21 includes a first height positioning element and a second height positioning element. The first height positioning element can simultaneously detect the height of the positive terminal of the battery cell and the corresponding positive welding point on the circuit board, and the second height positioning element can simultaneously detect the height of the negative welding pad of the battery cell and the corresponding negative welding point on the circuit board. The first and second height positioning elements can operate simultaneously, thereby improving production efficiency. In this embodiment, both the first and second height positioning elements are laser displacement sensors.

[0034] The planar positioning component 22 includes a positioning CCD and a light source for supplementary lighting during imaging. The positioning CCD can acquire the planar coordinates of the positive electrode post, negative electrode pad, and corresponding positive and negative electrode welding points on the battery cell protection board through visual imaging, thereby achieving planar positioning of the battery cell. Precise positioning of the battery cell can be achieved through the cooperation of the height positioning component 21 and the planar positioning component 22.

Both the first drive assembly 32 and the second drive assembly 33 can be drive cylinders or drive motors. The laser welding assembly 31 can move back and forth between the positive electrode conductive sheet welding station and the negative electrode conductive sheet welding station.

[0036] In some embodiments, the battery cell conductive sheet welding equipment further includes a first welding fixing mechanism 7 and a second welding fixing mechanism 8 respectively disposed on opposite sides of the battery cell conveying mechanism 1. The second welding fixing mechanism 8 is located on the side of the battery cell conveying mechanism 1 close to the first feeding mechanism 4. The first welding fixing mechanism 7 is used to fix the position of the positive electrode post of the battery cell and the position of the negative electrode pad of the battery cell. The second welding fixing mechanism 8 is used to fix the corresponding positive and negative electrode welding points of the battery cell circuit board.

[0037] The first welding and fixing mechanism 7 includes a first clamping claw assembly 71, a second clamping claw assembly 72, and a third driving assembly 73. Both the first clamping claw assembly 71 and the second clamping claw assembly 72 are connected to the driving end of the third driving assembly 73. The third driving assembly 73 simultaneously drives the first clamping claw assembly 71 and the second clamping claw assembly 72 to move horizontally. The driving direction of the third driving assembly 73 is parallel to the conveying direction of the battery cell conveying mechanism 1. The first clamping claw assembly 71 is used for pressing and fixing the positive electrode post of the battery cell, and the second clamping claw assembly 72 is used for pressing and fixing the negative electrode pad of the battery cell.

[0038] The second welding and fixing mechanism 8 includes a third pressure claw assembly 81 and a fourth drive assembly 82. The third pressure claw assembly 81 is connected to the drive end of the fourth drive assembly 82. The fourth drive assembly 82 is used to drive the third pressure claw assembly 81 to move horizontally, and the drive direction of the fourth drive assembly 82 is parallel to the conveying direction of the cell conveying mechanism 1. The third pressure claw assembly 81 is used to press and fix the corresponding positive electrode welding point or the corresponding negative electrode welding point of the cell circuit board. The third pressure claw assembly 81 can move back and forth between the positive electrode conductive sheet welding station and the negative electrode conductive sheet welding station under the drive of the fourth drive assembly 82.

[0039] In some embodiments, the first welding fixing mechanism 7 further includes a first cleaning component 74, which is connected to the drive end of the third drive component 73 and is used for cleaning the third pressure claw assembly 81. The second welding fixing mechanism 8 further includes a second cleaning component 83 and a dust suction component 84. The second cleaning component 83 is connected to the drive end of the fourth drive component 82, and the dust suction component 84 is connected to one side of the third pressure claw assembly 81. The dust suction component 84 can remove welding slag and dust during the welding process, and the second cleaning component 83 is used for cleaning the first pressure claw assembly 71 and the second pressure claw assembly 72.

Both the fourth driving member 742 and the fifth driving member 832 can be driving cylinders.

[0041] When the welding operation is completed, the first cleaning brush 741 can move to the corresponding position of the third pressure claw assembly 81 under the drive of the third drive component 73, and then extend under the drive of the fourth drive component 742, so that the pressure head of the third pressure claw assembly 81 is located in the first cleaning brush 741. Afterwards, the first cleaning brush 741 moves back and forth under the drive of the third drive component 73, and fully rubs against the pressure head of the third pressure claw assembly 81, thereby cleaning the third pressure claw assembly 81. The cleaning process of the second cleaning brush 831 on the first pressure claw assembly 71 and the second pressure claw assembly 72 is the same as that of the first cleaning brush 741, and will not be described in detail here.
