Referring to fig. 8 to 10, in an embodiment of the present invention, the steel strip pulling device 30 includes a fixed base 32, a mounting frame 33, and a steel strip pulling mechanism 34. The fixed base 32 is disposed on the base 11, and the mounting bracket 33 is disposed on the fixed base 32 and can be controlled to move reciprocally along the first direction e relative to the fixed base 32. Steel strip pulling mechanism 34 is disposed on mounting frame 33 and is controlled to move reciprocally with respect to mounting frame 33 along second direction f, and steel strip pulling mechanism 34 can grab the first end or the second end of steel strip B bent in second direction f. In this way, after the first end and the second end of the steel strip B are bent in the second direction f, the steel strip pulling mechanisms 34 of the two steel strip pulling devices 30 move towards the first end and the second end of the steel strip B along the second direction f respectively until the first end and the second end of the steel strip B are grabbed, and then return along the second direction f to tighten the first end and the second end of the steel strip B. After the steel strip B is tensioned in place, the steel strip pulling mechanism 34 moves along the mounting frame 33 towards the pile A along the first direction e, so that the first end and the second end of the steel strip B are attached to the pile A, and the welding quality is ensured.
In the embodiment, the steel strip pulling device 30 further includes a third moving driving assembly 31, the third moving driving assembly 31 is disposed on the base 11, and the fixed base 32 is connected to the third moving driving assembly 31 in a transmission manner. The third movement driving assembly 31 can drive the fixed base 32 to move back and forth along the third direction, so as to drive the steel strip pulling mechanism 34 to enter or exit the third working position for pulling the first end or the second end of the steel strip B. When it is desired to pull steel strip B, third movement driving assembly 31 may drive fixed base 32 to move in a third direction, thereby driving steel strip pulling mechanism 34 into a third operating position in preparation for pulling the first end or the second end of steel strip B. When strip B is completed, third movable drive assembly 31 may drive fixed base back in a third direction, thereby moving strip pulling mechanism 34 out of the third working position to provide working space for other mechanisms (e.g., strip threading mechanism 21 and profiling mechanism 22).
Referring to fig. 12 and 13, in some embodiments, strip pulling mechanism 34 includes a movable base 341, a strip pulling base 342, and a drive assembly. The movable base 341 is disposed on the mounting frame 33 and is controlled to reciprocate along the second direction f relative to the mounting frame 33. Since the mounting frame 33 is reciprocally movable in the first direction e relative to the fixed base 32, the movable base 341 is controllably reciprocally movable in the first direction e and the second direction f relative to the fixed base 32. The steel strip B is locked or unlocked by the pulling strip seat 342 being reciprocatably coupled to the moving seat 341 in the first direction e and being reciprocatingly moved in the first direction e with respect to the moving seat 341. The driving assembly includes a lock driving member 343, a first link 344, and a second link 345. The lock actuator 343 includes a fixed end and a telescoping end that is extendable and retractable relative to the fixed end. The fixed end is hinged to the steel belt drawing seat 342, the telescopic end is hinged to one end of the first link 344 and one end of the second link 345, and the other end of the first link 344 and the other end of the second link 345 are hinged to the movable seat 341 and the steel belt drawing seat 342 respectively.
The telescopic end includes a locking position (see fig. 13) in the process of extending and retracting the fixed end, when the telescopic end is located at the locking position, the first link 344 and the second link 345 drive the steel pulling strip seat 342 to move to the first end or the second end of the steel locking strip B along the first direction e, and the first link 344 and the second link 345 are parallel to the first direction e and are in a self-locking state.
In this way, when the first end and the second end of the steel strip B are bent in the second direction f, the moving base 341 moves in the second direction f so that the steel strip pulling base 342 moves to the first end or the second end of the steel strip B. The telescopic end of the lock driving member 343 is extended with respect to the fixed end, thereby pushing the pull steel strip holder 342 to move in the first direction e until the first end or the second end of the lock steel strip B by the first link 344 and the second link 345. The movable base 341 is returned in the second direction f to tighten the steel strip B. When the steel band B is tightened in place, the moving seat 341 moves along the first direction e toward the stack a along with the mounting frame 33, so that the first end and the second end of the steel band B are closely attached to the stack a, thereby improving the welding quality. Then, the welding device 40 welds the first and second ends of the steel strip B to the cell stack a, respectively. After the welding is completed, the telescopic end of the locking driving member 343 is contracted with respect to the fixed end, thereby pulling the steel strip holder 342 to move in the first direction e through the first link 344 and the second link 345 until the first end and the second end of the steel strip B are released.
When the telescopic end is located at the locking position, the first link 344 and the second link 345 drive the steel pulling strip seat 342 to move to the first end or the second end of the steel locking strip B along the first direction e, and the first link 344 and the second link 345 are parallel to the first direction e and are in a self-locking state. Then, the movable base 341 moves along the mounting frame 33 toward the stack a along the first direction e, so that in the process that the first end or the second end of the steel strip B is tightly attached to the stack a, since the first link 344 and the second link 345 are parallel to the first direction e, the component force (i.e., the horizontal component force) of the tensile force on the steel strip B along the first direction e and the steel strip resilience force cannot push the first link 344 and the second link 345 to rotate, so that the first link 344 and the second link 345 always maintain a self-locking state. That is, by utilizing the self-locking of the first link 344 and the second link 345, the steel strip pulling seat 342 is prevented from being pushed to move along the first direction e under the action of the component force (i.e. horizontal component force) of the steel strip pulling force along the first direction e and the steel strip resilience force, so that a gap is generated between the steel strip B and the pile a, poor welding is caused, and the welding effect is prevented from being influenced.
In an embodiment, the telescopic end further includes a release position (see fig. 12) during the process of extending and retracting the opposite fixed end, when the telescopic end is located at the release position, the first link 344 and the second link 345 drive the steel pulling strip seat 342 to move along the first direction e to the first end or the second end of the steel strip B, and the first link 344 and the second link 345 are disposed at an angle, that is, they are not parallel to the first direction e.
Further, a steel belt latch 3421 is connected to a side of the steel belt drawing base 342 facing away from the driving assembly, and the steel belt latch 3421 can be inserted into or withdrawn from the latch hole C of the first end or the second end of the steel belt B during the reciprocating movement of the steel belt drawing base 342 along the first direction e. When the pull strap mount 342 is moved to the locking position in the first direction e, the strap latch 3421 is inserted into the latch hole C of the first or second end of the strap B, thereby locking the first or second end of the strap B. When the steel strip pulling seat 342 moves to the release position along the first direction e, the steel strip latch 3421 exits the latch hole C of the first end or the second end of the steel strip B, and the first end and the second end of the steel strip B are separated from the steel strip pulling seat 342.
Further, the steel strip pulling mechanism 34 further includes a steel strip backup plate 346 connected to the moving base 341. The steel belt backup plate 346 is disposed opposite to one side of the steel belt base 342 having the steel belt bolt 3421, and has a fitting hole 3461 through which the steel belt bolt 3421 passes.
In this way, after the first end and the second end of the steel strip B are bent in the second direction f, the movable base 341 moves in the second direction f to be close to the first end or the second end of the steel strip B, so that the first end or the second end of the steel strip B is inserted between the steel strip pulling base 342 and the steel strip backup plate 346. The telescopic end of the locking driving member 343 is extended with respect to the fixed end, so that the steel strip pulling seat 342 is pushed by the first link 344 and the second link 345 to move toward the steel strip backup plate 346 in the first direction e until the steel strip latch 3421 penetrates through the latch hole C of the first end or the second end of the steel strip B and is inserted into the fitting hole 3461 of the steel strip backup plate 346, thereby locking the first end or the second end of the steel strip B. The movable base 341 is returned in the second direction f to tighten the steel strip B. When the steel band B is tightened in place, the moving seat 341 moves along the first direction e toward the stack a along with the mounting frame 33, so that the first end and the second end of the steel band B are closely attached to the stack a, thereby improving the welding quality. Then, the welding device 40 welds the first and second ends of the steel strip B to the cell stack a, respectively. After welding, the telescopic end of the locking driving member 343 is contracted relative to the fixed end, so that the steel strip pulling seat 342 is pulled by the first link 344 and the second link 345 to move away from the steel strip backup plate 346 along the first direction e, so that the steel strip latch 3421 sequentially exits the fitting hole 3461 of the steel strip backup plate 346 and the latch hole C of the first end or the second end of the steel strip B, i.e. the first end or the second end of the steel strip B is released.
