In an embodiment, the tab rewinding device further includes a substrate 40, and the first unwinding assembly 11, the second unwinding assembly 12 and the first fixing and clamping assembly 24 are all mounted on the substrate 40. The transfer plate 21 of the reel change mechanism is movably connected to the base plate 40 in a first direction. Therefore, all parts of the tab coil changing device are integrated on the substrate 40, which is beneficial to improving the structure compactness and reducing the space occupied by the tab coil changing device.
Further, the reel changing mechanism further comprises a reel changing driving member 27, wherein the reel changing driving member 27 is disposed on the substrate 40 and is in transmission connection with the transfer plate 21 to drive the transfer plate 21 to move back and forth along the first direction relative to the substrate 40. Alternatively, the reel change drive 27 may be a pneumatic cylinder.
Further, a slider is fixedly connected to the transfer plate 21, and a slide rail 42 extending lengthwise in the first direction is fixedly connected to the base plate 40. The slider is slidably connected to the slide rail 42, so that the carrying plate 21 is movable in a first direction relative to the base plate 40.
Further, the substrate 40 has a back surface and a front surface opposite to the back surface, and the transfer plate 21 and the reel changer 27 are both located on the back surface of the substrate 40. The substrate 40 is formed with a through hole 41 penetrating the back and front surfaces to expose a portion of the transfer plate 21. The cutting mechanism 30, the first floating clamping assembly 22 and the second floating clamping assembly 23 are all located at the portion of the transfer plate 21 exposed by the through hole 41, so that the layout is more reasonable, the structure is more compact, and the maintenance is convenient.
In an embodiment, the moving plate 21 includes a first position and a second position during the process of moving back and forth along the first direction.
When the transfer plate 21 moves to the first position, the first floating clamping assembly 22 aligns with the first fixed clamping assembly 24, the tape splicing mechanism 70 is used for connecting the tab material tape a clamped by the first floating clamping assembly 22 and the tab material tape a clamped by the first fixed clamping assembly 24, and the cutting mechanism 30 is used for cutting off the tab material tape a clamped by the first floating clamping assembly 22 and the first fixed clamping assembly 24 together. It should be noted that, the actions of the tape splicing mechanism 70 and the cutting mechanism 30 should be understood here that, after the transfer plate 21 moves to the first position during the next roll changing process, the tab material tape a clamped by the first floating clamping assembly 22 and the tab material tape a clamped by the first fixed clamping assembly 24 are connected by the tape splicing mechanism 70, so that the tab material tape a unreeled and output by the first unreeling assembly 11 is transported downstream through the first floating clamping assembly 22 and the first fixed clamping assembly 24 (i.e. at this time, the roll changing is completed, and the material tape output by the first unreeling assembly 11 is taken as the working material tape). When the unwinding of the first unwinding assembly 11 is completed and the reel needs to be changed again, the cutting mechanism 30 cuts off the tab material strip a clamped by the first floating clamping assembly 22 and the first fixed clamping assembly 24 together, so as to perform the subsequent reel changing operation. That is, when the transfer plate 21 moves to the first position, the tape splicing mechanism 70 connects the tab tape a clamped by the first floating clamping assembly 22 and the tab tape a clamped by the first fixed clamping assembly 24 to complete the current reel changing operation. However, the cutting mechanism 30 cuts the tab material strip a clamped by the first floating clamping assembly 22 and the first fixed clamping assembly 24 together in order to complete the next roll change operation.
When the transfer plate 21 moves to the second position (see fig. 1), the second floating clamping assembly 23 is aligned with the first fixed clamping assembly 24, the belt receiving mechanism 70 is configured to connect the tab material belt a clamped by the second floating clamping assembly 23 and the tab material belt a clamped by the first fixed clamping assembly 24, and the cutting mechanism 30 is configured to cut off the tab material belt a clamped by the second floating clamping assembly 23 and the first fixed clamping assembly 24 together. It should be noted that, the actions of the tape splicing mechanism 70 and the cutting mechanism 30 should be understood here that, after the transfer plate 21 moves to the second position during the next roll changing process, the tab material tape a clamped by the second floating clamping assembly 23 is connected with the tab material tape a clamped by the first fixed clamping assembly 24 by the tape splicing mechanism 70, so that the tab material tape a unreeled and output by the second unreeling assembly 12 is transported downstream through the second floating clamping assembly 23 and the first fixed clamping assembly 24 (i.e. at this time, the roll changing is completed, and the material tape output by the second unreeling assembly 12 is used as the working material tape). When the unwinding of the second unwinding assembly 12 is completed and the reel needs to be changed again, the cutting mechanism 30 cuts off the tab material strip a clamped by the second floating clamping assembly 23 and the first fixed clamping assembly 24 together, so as to perform the subsequent reel changing operation. That is, when the transfer plate 21 moves to the second position, the tape splicing mechanism 70 connects the tab tape a clamped by the second floating clamping assembly 23 and the tab tape a clamped by the first fixed clamping assembly 24 to complete the current reel changing operation. However, the cutting mechanism 30 cuts the tab material strip a clamped by the second floating clamping assembly 23 and the first fixed clamping assembly 24 together in order to complete the next roll change operation.
Further, the reel changing mechanism further comprises a second fixed clamping component 25 and a third fixed clamping component 26, and the second fixed clamping component 25 and the third fixed clamping component 26 are respectively arranged on two sides of the first fixed clamping component 24 in the first direction. More specifically, the second and third fixed clamp assemblies 25 and 26 are mounted on the base plate 40.
When the transfer plate 21 moves to the first position, the second floating clamping assembly 23 aligns with the third fixed clamping assembly 26, the third fixed clamping assembly 26 is used for clamping the tab material strip a passing through the second floating clamping assembly 23, and the cutting mechanism 30 is further used for cutting off the tab material strip a clamped by the second floating clamping assembly 23 and the third fixed clamping assembly 26 together. When the transfer plate 21 moves to the second position, the first floating clamping assembly 22 is aligned with the second fixed clamping assembly 25, the second fixed clamping assembly 25 is used for clamping the tab material strip a passing through the first floating clamping assembly 22, and the cutting mechanism 30 is further used for cutting off the tab material strip a clamped by the first floating clamping assembly 22 and the second fixed clamping assembly 25 together.
Taking the tab material belt a unreeled and output by the first unreeling assembly 11 as a working material belt, and the tab material belt a unreeled and output by the second unreeling assembly 12 as a standby material belt (i.e. the transfer plate 21 is located at the first position), a reel changing process is described as follows:
initially, the transfer plate 21 is located at a first position, and the tab material strip a unwound and outputted by the first unwinding assembly 11 passes through the first floating clamping assembly 22 and the first fixed clamping assembly 24 in sequence and is conveyed downstream. The end of the tab material belt a unreeled and output by the second unreeling assembly 12 is clamped by the second floating clamping assembly 23 and the third fixed clamping assembly 26.
When the tab material roll on the first unwinding assembly 11 runs out and needs to be changed, first, the first floating clamping assembly 22 and the first fixed clamping assembly 24 clamp the tab material strip a which is unwound and output by the first unwinding assembly 11. The cutting mechanism 30 cuts off the tab material strip a clamped by the first floating clamping assembly 22 and the first fixed clamping assembly 24 together (i.e. the tab material strip a unreeled and output by the first unreeling mechanism), and cuts off the tab material strip a clamped by the second floating clamping assembly 23 and the third fixed clamping assembly 26 together (i.e. the tab material strip a unreeled and output by the second unreeling mechanism). Work material area and reserve material area all are cut off promptly to be favorable to controlling the length that the second floated centre gripping subassembly 23 was worn out to reserve material area, and then the second floats centre gripping subassembly 23 and aligns with first fixed centre gripping subassembly 24 the end that cuts off of reserve material area and the end that cuts off in work material area can be better the matching, the end that cuts off that is convenient for follow-up tape splicing mechanism 70 to connect this reserve material area and the end that cuts off in work material area.
