[0002] During the die-cutting process, it is often necessary to transfer the workpiece on the first film material to the second film material.

[0003] In the related art, when transferring, a puller is required to pull the first film material and the second film material synchronously through two composite rollers of a composite roller group. Under the composite action of the composite roller group, the workpiece on the first film material is transferred to the second film material.

[0004] However, since the first and second film materials need to drive the composite roller to rotate while the puller is pulling the first and second film materials, the first and second film materials themselves will also be deformed due to the large tension, thereby affecting the transfer accuracy of the workpiece.

[0044] Reference below Figures 1 to 4 The transfer process of the first aspect of the present invention is described in detail.

[0045] refer to Figure 1 According to the transfer process of the first embodiment of the present invention, the following steps are included but are not limited to:

[0046] Step S100, driving two composite rollers of the composite roller group 300 to move away from each other, wherein a transfer area is formed between the two composite rollers;

[0047] Step S200, driving the first film material 400 to move, so that the workpiece 410 on the first film material 400 moves to the transfer area;

[0048] Step S300, driving the second film material 500 to move so that the bonding area 510 on the second film material 500 moves to the transfer area;

[0049] Step S400, driving two composite rollers to approach each other to transfer the workpiece 410 on the first film material 400 to the laminating area 510 on the second film material 500;

[0050] Step S500 , repeat the above steps until all the workpieces 410 on the first film material 400 are transferred to the bonding area 510 on the second film material 500 .

[0051] It should be noted that after the composite roller group 300 compositely transfers the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500, it is necessary to drive the first film material 400 and the second film material 500 to move so that the next workpiece 410 on the first film material 400 and the next bonding area 510 on the second film material 500 move to the transfer area. However, during the movement of the first film material 400 and the second film material 500, due to the obstruction of the composite roller group 300, the first film material 400 and the second film material 500 will generate greater tension themselves, thereby causing deformation. Over time, greater cumulative errors will occur on the first film material 400 and the second film material 500, thereby affecting the transfer accuracy of the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500.

[0052] It can be understood that in the transfer process of the present invention, the two composite rollers of the composite roller group 300 are first driven away from each other, wherein a transfer area is formed between the two composite rollers, and then the first film material 400 is driven to move so that the workpiece 410 on the first film material 400 moves to the transfer area, and then the second film material 500 is driven to move so that the bonding area 510 on the second film material 500 moves to the transfer area, and then the two composite rollers are driven close to each other to transfer the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500, and then the above steps are repeated until all the workpieces 410 on the first film material 400 are transferred to the bonding area 510 on the second film material 500. After the composite roller group 300 compositely transfers one of the workpieces 410 on the first film material 400 to the bonding area 510 of the second film material 500, the two composite rollers of the composite roller group 300 can move away from each other to reduce the resistance encountered by the first film material 400 and the second film material 500 during the movement, thereby reducing the deformation of the first film material 400 and the second film material 500 during the movement, thereby improving the transfer accuracy of the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500.

[0053] In some embodiments of the present invention, step S100 includes but is not limited to the following steps:

[0054] Step S110, determine whether the previous workpiece 410 has left the transfer area, drive the two composite rollers away from each other, so that the composite roller group 300 switches from the composite state to the separated state. When the composite roller group 300 is in the composite state, the composite roller group 300 can compositely transfer the workpiece 410 in the transfer area to the bonding area 510.

[0055] It should be noted that when the composite roller group 300 is in a composite state, the two composite rollers of the composite roller group 300 are adjacent. At this time, when the first film material 400 and the second film material 500 pass through the transfer area, the two composite rollers of the composite roller group 300 cooperate to extrude the first film material 400 and the second film material 500, so that the workpiece 410 on the first film material 400 can be normally composited and transferred to the bonding area 510 of the second film material 500; when the composite roller group 300 is in a separated state, the two composite rollers of the composite roller group 300 are spaced a long distance apart. At this time, when the first film material 400 and the second film material 500 pass through the transfer area, the two composite rollers of the composite roller group 300 are difficult to cooperate to extrude the first film material 400 and the second film material 500, and the first film material 400 and the second film material 500 can pass through the transfer area normally.

[0056] It can be understood that, before the previous workpiece 410 leaves the transfer area and before the next workpiece 410 enters the transfer area, the composite roller group 300 does not need to perform a composite action. On the contrary, when the composite roller group 300 is in a composite state, it will affect the normal passage of the first film material 400 and the second film material 500 through the transfer area, thereby causing the first film material 400 and the second film material 500 to undergo a larger deformation. In the transfer process of this embodiment, after the previous workpiece 410 leaves the transfer area, the two composite rollers of the composite roller group 300 can move away from each other, so that the composite roller group 300 switches from a composite state to a separated state. In this case, the first film material 400 and the second film material 500 can pass through the transfer area smoothly, and the composite roller group 300 has less obstruction to the first film material 400 and the second film material 500 during their movement, so as to reduce the deformation of the first film material 400 and the second film material 500 during their movement.

[0057] In some embodiments of the present invention, reference Figure 2 In step S400, the following steps are included but not limited to:

[0058] Step S410, determining that the current workpiece 410 enters the transfer area, driving the two composite rollers to approach each other, so that the composite roller group 300 switches from the separation state to the composite state;

[0059] Step S420: Keep the composite roller set 300 in the composite state until the current workpiece 410 is completely transferred to the transfer area.

[0060] It can be understood that when the workpiece 410 enters the transfer area, the two composite rollers of the composite roller group 300 need to cooperate to squeeze the first film material 400 and the second film material 500 in the transfer area, so that the workpiece 410 on the first film material 400 is transferred to the bonding area 510 on the second film material 500; therefore, after the workpiece 410 enters the transfer area, the composite roller group 300 switches from a separated state to a composite state, and remains in the composite state until the workpiece 410 leaves the transfer area, so that the workpiece 410 on the first film material 400 can be smoothly transferred to the bonding area 510 of the second film material 500.

[0061] In some embodiments of the present invention, reference Figure 3 , the interval between any two adjacent workpieces 410 on the first film material 400 is l1, the moving speed of the first film material 400 is v1, and step S410 includes but is not limited to the following steps:

[0062] Step S411, start timing from when the last workpiece 410 leaves the transfer area, and after a preset time T has passed, determine that the current workpiece 410 enters the transfer area, wherein the preset time satisfies: T=l1 / v1.

[0063] It can be understood that after the preset time T, the head end of the current workpiece 410 on the first film material 400 can just enter the transfer area. At this time, the composite roller group 300 needs to switch from the separation state to the composite state to transfer the current workpiece 410 on the first film material 400 to the bonding area 510 of the second film material 500.

[0064] In some embodiments of the present invention, reference Figure 3 and Figure 4 , the workpieces 410 on the first film material 400 are arranged at intervals of l2 along the extension direction of the first film material 400, and the bonding areas 510 on the second film material 500 are arranged at intervals of l3 along the extension direction of the second film material 500. The moving speed of the second film material 500 is v2, and the moving speed of the first film material 400 and the moving speed of the second film material 500 satisfy: v1 / v2=l3 / l2.

[0065] It can be understood that since the moving speed of the first film material 400 and the moving speed of the second film material 500 satisfy: v1 / v2=l 32 Therefore, when the leading end of the workpiece 410 on the first film material 400 just enters the transfer area, the leading end of the bonding area 510 on the second film material 500 can also just enter the transfer area, thereby ensuring that the workpiece 410 on the first film material 400 can be accurately transferred to the bonding area 510 of the second film material 500.

[0066] Reference below Figure 5 The transfer device of the second embodiment of the present invention is described in detail.

[0067] The transfer device provided in accordance with the second aspect of the embodiment of the present invention is used to implement the transfer process provided in accordance with the first aspect of the embodiment of the present invention.

[0068] In some embodiments of the present invention, reference Figure 5 The transfer device includes a composite component 10, a first material pulling component and a second material pulling component. The composite component 10 includes a driving structure 100, a mounting frame 200 and a composite roller group 300. A transfer area is formed between two composite rollers of the composite roller group 300. The driving structure 100 is arranged on the mounting frame 200 and is connected to at least one of the composite rollers. The driving structure 100 is used to drive the composite roller to approach or move away from the transfer area. The first material pulling component is arranged on one side of the composite component 10 and is used to pull the first film material 400 through the transfer area. The second material pulling component is arranged on one side of the composite component 10 and is used to pull the second film material 500 through the transfer area.

[0069] For example, Figure 5 As shown, the composite component 10 includes a driving structure 100, a mounting frame 200 and a composite roller group 300. The composite roller group 300 includes two composite rollers distributed in a vertical direction, and both composite rollers are extended in the left-right direction to form a transfer area between the two composite rollers. The driving structure 100 is arranged on the mounting frame 200 and is connected to at least one composite roller.

[0070] It can be understood that, under the pulling of the first material pulling component, the first film material 400 can move from front to back to pass through the transfer area, and under the pulling of the second material pulling component, the second film material 500 can move from front to back to pass through the transfer area; when the workpiece 410 on the first film material 400 and the bonding area 510 on the second film material 500 both enter the transfer area, the driving structure 100 can drive the two composite rollers to approach each other, so that the composite roller group 300 switches from the separation state to the composite state. At this time, the composite roller group 300 can smoothly transfer the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500. 10 is compositely transferred to the bonding area 510 of the second film material 500. When the workpiece 410 on the first film material 400 and the bonding area 510 on the second film material 500 leave the transfer area, the driving structure 100 can drive the two composite rollers to move away from each other, so that the composite roller group 300 switches from the composite state to the separation state. At this time, the two composite rollers of the composite roller group 300 can move away from the first film material 400 and the second film material 500, so that the first film material 400 and the second film material 500 can move smoothly backwards under the pulling of the first pulling component and the second pulling component respectively.

[0071] In a further embodiment of the present invention, the two composite rollers are respectively a first composite roller 310 and a second composite roller 320. The second composite roller 320 is rotatably disposed on a mounting frame 200. A slider 210 is slidably disposed on the mounting frame 200 in a vertical direction. The first composite roller 310 is rotatably disposed on the slider 210. The driving structure 100 includes a driver 110 and a transmission structure 120. The driver 110 is connected to the slider 210 via the transmission structure 120. The driver 110 can drive the slider 210 to perform lifting movements via the transmission structure 120.

[0072] For example, Figure 5 As shown, two composite rollers are distributed in the vertical direction, wherein the composite roller located on the upper side is the first composite roller 310, and the composite roller located on the lower side is the second composite roller 320. The second composite roller 320 is rotatably disposed on the mounting frame 200. A slider 210 is disposed on the mounting frame 200. The slider 210 is slidably disposed in the vertical direction. The first composite roller 310 is rotatably disposed on the slider 210. The driving structure 100 includes a driver 110 and a transmission structure 120. The driver 110 is disposed on the mounting frame 200, and the output end of the driver 110 is transmission-connected to the slider 210 via the transmission structure 120.

[0073] It can be understood that, driven by the driver 110, the transmission structure 120 can drive the slider 210 to move up and down, so that the slider 210 can drive the first composite roller 310 to approach or move away from the second composite roller 320 in the vertical direction, thereby realizing the switching of the composite roller group 300 between the composite state and the separation state.

[0074] In some embodiments of the present invention, reference Figure 5 The transmission structure 120 includes a transmission plate 121 and a transmission rod 122. The transmission rod 122 is extended in the vertical direction. The transmission rod 122 is connected to the slider 210. The transmission rod 122 is slidably arranged in the transmission plate 121 in the vertical direction. The transmission rod 122 is provided with a first abutting protrusion 122a and a second abutting protrusion 122b. The first abutting protrusion 122a is used to abut against the upper plate surface of the transmission plate 121, and the second abutting protrusion 122b is used to abut against the lower plate surface of the transmission plate 121. The driver 110 is connected to the transmission plate 121 and is used to drive the transmission plate 121 to perform lifting movements.

[0075] It can be understood that when the driver 110 needs to drive the first composite roller 310 to rise, the driver 110 can drive the transmission plate 121 to move upward, so that the transmission plate 121 can abut against and push the first abutment protrusion 122a upward, so that the transmission plate 121 can drive the transmission rod 122 to move upward, and then the transmission rod 122 can drive the slider 210 and the first composite roller 310 to move upward, and the composite roller group 300 switches from the composite state to the separated state; when the driver 110 needs to drive the first composite roller 310 to descend, the driver 110 can drive the transmission plate 121 to move downward, so that the transmission plate 121 can abut against and push the second abutment protrusion 122b downward, so that the transmission plate 121 can drive the transmission rod 122 to move downward, and then the transmission rod 122 can drive the slider 210 and the first composite roller 310 to move downward, and the composite roller group 300 switches from the separated state to the composite state.

[0076] In a further embodiment of the present invention, reference Figure 5 The distance between the first abutment protrusion 122a and the second abutment protrusion 122b is greater than the thickness of the transmission plate 121 in the vertical direction; an elastic connecting member 220 is also provided on the mounting frame 200, and the elastic connecting member 220 is respectively connected to the slider 210 and the mounting frame 200, and the elastic connecting member 220 is used to provide an elastic force to keep the first composite roller 310 close to the second composite roller 320.

[0077] It can be understood that since the elastic connecting member 220 is respectively connected to the slider 210 and the mounting frame 200, and the elastic connecting member 220 is used to provide an elastic force to keep the first composite roller 310 close to the second composite roller 320, and then, when the composite roller group 300 is in a composite state, the elastic connecting member 220 can keep the first composite roller 310 close to the second composite roller 320, so that the composite roller group 300 can smoothly composite and transfer the workpiece 410 on the first film material 400 to the bonding area 510 of the second film material 500.

[0078] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
