The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

An unwinding device 100 according to an embodiment of the present application is described below with reference to fig. 1 to 3.

As shown in fig. 1, according to an unwinding device 100 of an embodiment of the first aspect of the present application, the unwinding device 100 is used for unwinding a tape 200, and the unwinding device 100 includes: a frame (not shown), a winding roller 10 and a moving device 20; the winding roller 10 is rotatably arranged on the frame to unwind the belt material 200; the mobile device 20 includes: the horizontal moving mechanism 21 is connected with the frame and is movable relative to the winding roller 10, and the swinging mechanism 22 is movable relative to the horizontal moving mechanism 21 so as to absorb the retraction of the belt material 200 during the movement of the horizontal moving mechanism 21.

Referring to fig. 1, specifically, a driving motor and a linear motor are arranged on the frame, the driving motor is adapted to drive the winding roller 10 to rotate so as to enable the strip 200 to enter the moving device 20, and the linear motor is adapted to control the strip 200 extending out of the winding roller 10; the horizontal moving mechanism 21 can drive the belt material 200 to move in the horizontal direction, the swinging mechanism 22 is installed on the horizontal moving mechanism 21, and then in the unwinding process, the swinging mechanism 22 can absorb the retraction of the belt material 200 or make the retracted part of the belt material 200 extend again through the swinging of the swinging mechanism 22 according to the unwinding requirement of the belt material 200.

It is understood that fig. 1 is a schematic view of the moving device 20 disposed on the left side of the lamination station 300 according to an embodiment of the present application. Fig. 2 is a schematic diagram of the moving device 20 disposed on the right side of the lamination station 300 according to an embodiment of the present application. Fig. 3 is a schematic diagram of the moving device 20 disposed directly above the lamination station 300 according to an embodiment of the present application.

It should be noted that the linear motor is adapted to control the strip 200 extending out of the winding roller 10, which means that the linear motor is adapted to adjust the overall tension of the strip 200 and the length of the strip 200 extending out of the winding roller 10 after the strip 200 wound around the winding roller 10 moves out of the winding roller 10.

According to the unwinding device 100 of the embodiment of the present application, by providing the swing mechanism 22, the retraction of the belt material 200 can be effectively absorbed or the portion of the belt material 200 retracted by the swing mechanism 22 can be extended again. Thus, on one hand, the degree of alignment of the unreeled tape 200 can be made higher; on the other hand, the swing mechanism 22 can reduce the tension of the strip 200 and effectively reduce the acceleration of the linear motor during commutation, thereby preventing the strip 200 from being separated from the roller and improving the working stability of the unwinding device 100.

Certainly, the unwinding device 100 in the embodiment of the present application has the beneficial technical effects that the unwinding device is not limited thereto, and it can be understood that the acceleration of the linear motor during the reversing is reduced, so that the linear motor reacts more sensitively to the steering, and the requirement on the following performance of the linear motor can be reduced; meanwhile, the alignment degree of the unwinding device 100 is higher, so that the rotating speeds of the linear motor and the driving motor can be set faster, and the cycle time (cycle time) of the unwinding device 100 can be shortened, and the production efficiency can be improved.

As shown in fig. 2 or 3, the horizontal movement mechanism 21 includes: a first mounting plate 211, a first pair of rollers 212 and a second pair of rollers 213; the first mounting plate 211 is movably connected with the frame; the first pair of rollers 212 is provided on the first mounting plate 211; the second pair of rollers 213 is arranged on the first mounting plate 211 and spaced from the first pair of rollers 212; wherein, the first pair of rollers 212 and the second pair of rollers 213 are arranged on the conveying path of the belt material 200 in sequence; the swing mechanism 22 is provided between the first pair of rollers 212 and the second pair of rollers 213.

Specifically, the first pair of rollers 212 and the second pair of rollers 213 are disposed opposite to each other on the first mounting plate 211, and the web 200 passes through the first pair of rollers 212, the swing mechanism 22 between the first pair of rollers 212 and the second pair of rollers 213, and the second pair of rollers 213 in this order. In this way, the swing mechanism 22 is disposed between the first pair of rollers 212 and the second pair of rollers 213, and during the unwinding of the tape 200, whether the swing mechanism 22 swings or not, the tape 200 can smoothly pass through the conveying path of the tape 200, and the swing mechanism 22 does not interfere with surrounding components during the swing, so that the operation stability of the unwinding device 100 can be further improved.

In the particular embodiment shown in FIG. 3, the first pair of rollers 212 includes a first clamping roller 212a and a second clamping roller 212b adapted to clamp the web 200, the first clamping roller 212a being rotatably mounted to the first mounting plate 211, the second clamping roller 212b being rotatably mounted to the first mounting plate 211; the second pair of rollers 213 includes a third clamping roller 213a and a fourth clamping roller 213b adapted to clamp the belt 200, the third clamping roller 213a is rotatably disposed on the first mounting plate 211, and the fourth clamping roller 213b is rotatably disposed on the first mounting plate 211.

In other words, when the first nip roller 212a rotates clockwise, the second nip roller 212b disposed opposite thereto rotates counterclockwise, so that the web 200 passing therebetween can be smoothly transferred to the next node (i.e., the position where the second pair of rollers 213 are located); similarly, the third nip roller 213a and the fourth nip roller 213b can smoothly transport the strip 200 to the next node. Therefore, the transportation smoothness of the belt 200 can be further improved, and the excessive tension of the belt 200 or the breakage of the belt 200 can be effectively avoided.

It is understood that the movement locus of the horizontal movement mechanism 21 is an arc or a straight line. That is, in some embodiments, the horizontal movement mechanism 21 performs an arc motion, and in other embodiments, the horizontal movement mechanism 21 performs a linear motion.

As shown in fig. 1 to 3, the swinging mechanism 22 includes a first end and a second end opposite to each other, the first end is rotatably connected to the horizontal moving mechanism 21, and the second end is swingable about the first end. Therefore, on the premise that the swinging mechanism 22 swings relative to the horizontal moving mechanism 21, the connection structure between the swinging mechanism 22 and the horizontal moving mechanism is simpler, so that the swinging mechanism 22 can swing more simply and easily, and the production cost of the unwinding device 100 is reduced.

As shown in fig. 3, the swing mechanism 22 includes: a second mounting plate 221 and a third pair of rollers 222, wherein the second mounting plate 221 is connected with the horizontal moving mechanism 21, the second mounting plate 221 comprises a third end and a fourth end which are oppositely arranged, and the third end is close to the first end; the third pair of rollers 222 is connected to the second mounting plate 221, and the third pair of rollers 222 is provided at the fourth end.

Specifically, the third pair of rollers 222 includes a fifth clamping roller 222a and a sixth clamping roller 222b adapted to clamp the belt 200, the fifth clamping roller 222a is rotatably disposed on the second mounting plate 221, and the sixth clamping roller 222b is rotatably disposed on the second mounting plate 221. Thus, the belt 200 sequentially passes through the first pair of rollers 212, the third pair of rollers 222, and the second pair of rollers 213, and the fifth nip roller 222a and the sixth nip roller 222b of the third pair of rollers 222 are rotated, so that the belt 200 is prevented from being stuck when the swing mechanism 22 swings.

As shown in fig. 1 to 3, it can be understood that the unwinding device 100 further includes: and the guide roller 30, the guide roller 30 is rotatably arranged on the frame, the guide roller 30 is suitable for supporting the belt material 200, and the guide roller 30 is positioned at the upstream of the moving device 20 on the unwinding path of the belt material 200. Specifically, the guide roller 30 is pivotally connected to the frame to provide a guide for the movement of the tape 200, so as to further improve the unwinding effect of the unwinding device 100.

Further, the unwinding device 100 further includes: and a moving roller 40, the moving roller 40 being provided on the frame, the moving roller 40 being adapted to support the strip 200, the moving roller 40 being located upstream of the moving device 20 on an unwinding path of the strip 200, the moving roller 40 being movable relative to the horizontal moving mechanism 21 to absorb a retraction of the strip 200 during movement of the horizontal moving mechanism 21.

In other words, the moving roller 40 can be driven by the linear motor to move linearly, so as to absorb the retraction of the belt 200 or extend the retracted portion of the belt 200 again, and act on the belt 200 synchronously with the swing mechanism 22, so that the retraction effect of the recovered belt 200 is better, and the unwinding effect of the unwinding device 100 can be further improved.

The lamination device 1000 according to an embodiment of the second aspect of the present application includes: an unwinding device 100 and a lamination station 300; the unwinding device 100 is the unwinding device 100 in the above embodiment; the laminating table 300 is arranged at a distance from the unwinding device 100, the unwinding device 100 is adapted to convey the strip 200 to the laminating table 300, the laminating table 300 is stationary relative to the winding roller 10, and the moving device 20 moves relative to the laminating table 300 to laminate the strip 200.

According to the lamination device 1000 of the embodiment of the application, by adopting the unwinding device 100, on one hand, the unwinding device 100 has a better unwinding effect, and the alignment degree of the strip 200 is higher, so that the requirement on the installation accuracy of the components of the whole mechanical device (namely, the lamination device 1000) can be reduced, and the installation cost of the lamination device 1000 is lower; on the other hand, the production efficiency of the lamination device 1000 can be effectively improved.

The operation of the lamination device 1000 using the novel embodiment will be described in detail below.

The lamination device 1000 includes: unwinding device 100, tape 200, and lamination station 300.

Wherein, unwinding device 100 includes: the winding roller 10, the moving device 20, the guide roller 30 and the moving roller 40; the moving device 20 includes a horizontal moving mechanism 21 and a swinging mechanism 22.

As shown in fig. 2 and 3, when the web 200 moves from left to right, in the first half of the left-to-right movement, the length of the web 200 between the guide roller 30 and the moving device 20 is reduced, and the length of the web 200 between the moving device 20 and the lamination stage 300 is also reduced simultaneously, and the reduced web 200 absorbs the retraction of the web 200 by the swing of the swing mechanism 22.

At this time, the moving roller 40 is not moved, and further, when the amount of retraction of the strip 200 starts to decrease, the swing mechanism 22 swings in reverse, the retracted strip 200 is released, and when the length of the retracted strip 200 released by the swing mechanism 22 cannot satisfy the stacking of the stacking table 300, the moving roller 40 moves to supply the strip 200 to the moving means, and after the moving means 20 completes the left-to-right moving process, one-time stacking of the strip 200 is completed.

It will be appreciated that after the moving device 20 moves to the right side of the lamination station 300, the movement is further reversed (i.e., right-to-left) to complete the "Z" shaped stacking of the tape 200 of the present embodiment.
