When the device is in use, the welding strip is located between the two correction rollers 11 in the correction module, and the correction roller 11 is in contact with the welding strip. When the correction module moves, the position of the welding strip can be changed to achieve correction of the welding strip position.

[0030] The present invention provides a welding strip clamping device for a battery cell string welding machine, which also includes a clamping structure.

When the electromagnet 1 25 is energized, the electromagnet 1 25 and the fixed sleeve 1 27 or the fixed sleeve 26 in contact therewith are magnetically attracted, and the telescopic direction of the hydraulic telescopic rod 5 29 is opposite to the telescopic direction of the hydraulic telescopic rod 6 23.

[0033] When the two electromagnets 25 on the movable frame 30 are in the energized state, the extension and retraction of the hydraulic telescopic rod 5 29 can change the position of the front rolling structure and the clamping assembly, and the front rolling structure and the clamping assembly can correct the welding strip and straighten the bent welding strip. When the two electromagnets 25 on the movable frame 24 are in the energized state, the extension and retraction of the hydraulic telescopic rod 6 23 can change the position of the clamping assembly and the rear rolling structure, and the rear rolling structure and the clamping assembly can correct the welding strip and straighten the bent welding strip.

[0034] The front rolling structure and the rear rolling structure have the same structure, and the front rolling structure and the rear rolling structure include a fixed plate 3 21, a fixed frame 2 31 connected to the fixed plate 3 21 through a hydraulic telescopic rod 4 22, and a roller 19 movably connected to the bottom end of the fixed frame 2 31. The roller 19 can straighten and press the welding strip.

[0035] The clamping assembly includes a support plate 33, a screw rod structure movably connected to the bottom of the support plate 33, a connecting rod 32 connected to the screw rod structure, and a clamping roller 28 movably sleeved with the outer ring of the bottom end of the connecting rod 32. The bottom of the connecting rod 32 is fixedly connected with an electromagnet 2. When the electromagnet 2 is powered on, the electromagnet 2 and the clamping roller 28 are magnetically attracted. The screw rod structure includes a double-headed ball screw 2 34 movably connected to the bottom of the support plate 33. Two adjacent double-headed ball screws 2 34 are in a fixed connection state.

The bottom of the support plate 33 is fixedly connected with a servo motor 3 16, and the end of the output shaft of the servo motor 3 16 is fixedly connected to the end of a double-headed ball screw 2 34 through a reducer. Through the setting of the clamping assembly, when the second electromagnet is in the power-on state, the clamping roller 28 and the connecting rod 32 are in a fixed connection state, and the clamping roller 28 can clamp and fix the welding strip, so that the device can drive the welding strip to move; when the second electromagnet is in the power-off state, the clamping roller 28 and the connecting rod 32 are in a movably connected state, and when the clamping roller 28 moves, the clamping roller 28 can straighten the welding strip.

[0036] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0037] To sum up: when the welding tape clamping device for the cell stringing machine is used, the clamping device is arranged at the input end of the photovoltaic cell conveyor line, the welding tape is located between the two correction rollers 11 in the correction module, and the servo motor 10 rotates. The rotation of the servo motor 10 changes the position of the correction roller 11 until the two correction rollers 11 in the correction module are in contact with the welding tape, and the end of the welding tape is located between the correction structure and the clamping structure. The visual sensor 12 detects the end of the welding tape located at the input end of the cell conveyor line. When the device needs to clamp the welding tape, the ball screw 13 rotates. The rotation of the ball screw 13 causes the clamping structure to move from the welding position of the cell to the input end of the cell conveyor line. The hydraulic telescopic rod 3 15 drives the clamping structure to move downward until the welding tape is located between the two clamping rollers 28 in the clamping assembly. The servo motor 3 16 works. The operation of the servo motor 3 16 causes the position of the two clamping rollers 28 in the clamping assembly to change until the clamping rollers 28 are tightly fitted to the welding tape.

[0038] When the visual sensor 12 detects that the end of the welding strip is bent, the hydraulic telescopic rod 3 works, and the operation of the hydraulic telescopic rod 3 causes the pressure roller 5 to press the welding strip to fix the position of the welding strip. The hydraulic telescopic rod 22 works, and the operation of the hydraulic telescopic rod 22 causes the roller 19 to be at the same height as the top of the welding strip. The two electromagnets 25 on the movable frame 30 are energized. The extension and retraction of the hydraulic telescopic rod 5 29 can change the position of the front rolling structure and the clamping assembly, and the front rolling structure and the clamping assembly can correct the welding strip. ; Straighten the bent welding strip, the two electromagnets 1 25 on the movable frame 24 are in a powered-on state, the extension and retraction of the hydraulic telescopic rod 6 23 can change the position of the clamping assembly and the rear rolling structure, the rear rolling structure and the clamping assembly can correct the welding strip, straighten the bent welding strip, and straighten the end of the welding strip. After the pressure of the pressure roller 5 on the welding strip is released or when the visual sensor 12 detects that the end of the welding strip is normal, the electromagnet 2 is in a powered-on state, the clamping roller 28 and the connecting rod 32 are in a fixedly connected state, and the welding strip is clamped and fixed by the clamping assembly.

[0039] The servo motor 18 drives the ball screw 13 to rotate. The rotation of the ball screw 13 makes the clamping structure move away from the correction structure. The clamping structure can drive the welding strip to move. During the movement of the welding strip, the correction roller 11 guides the welding strip. After the welding strip is pulled to a suitable length, the visual sensor 12 detects the position of the welding strip. When the welding strip position is offset, the pressure roller 5 presses the welding strip again. After the clamping roller 28 releases the clamping of the welding strip, the hydraulic telescopic rod 6 drives the correction roller 11 to move. The correction roller 11 can correct the position of the welding strip so that the welding strip and the main grid line of the battery cell are in a straight line to avoid the welding strip from being offset. After the welding strip position is corrected, the welding strip cutting structure in the prior art is used to cut the welding strip. After the welding strip is cut, the clamping structure can continue to clamp and pull the welding strip.
