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

[0003] In related technologies, during the transfer process, a puller needs to pull the first and second film materials simultaneously between the two composite rollers of the composite roller group. Under the combined action of the composite roller group, the workpiece on the first film material is transferred to the second film material.

[0004] However, as the puller moves the first and second film materials, the first and second film materials need to drive the composite roller to rotate.

[0044] The following refers to Figures 1 to 4 The transfer process of the first aspect of the present application is described in detail.

[0045] Reference Figure 1 According to the transfer process of the first aspect of the present application, the following

[0046] Step:

[0047] Step S100, drive the two composite rollers of the composite roller group 300 away from each other, wherein the two composite rollers form a transfer area between them;

[0048] Step S200, drive the first film material 400 to move, so that the workpiece 410 on the first film material 400 moves to the transfer area;

[0049] Step S300, drive the second film material 500 to move, so that the bonding area 510 on the second film material 500 moves to the transfer area;

[0050] Step S400, drive the two composite rollers to approach each other, so as to transfer the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500;

[0051] Step S500, repeat the above steps until the workpiece 410 on the first film material 400 is transferred to the bonding area 510 on the second film material 500.

[0052] It should be noted that after the composite roller group 300 composites and transfers the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500, the first film material 400 and the second film material 500 need to be driven 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, but in the process of moving the first film material 400 and the second film material 500, the first film material 400 and the second film material 500 will generate a large tension due to the blocking effect of the composite roller group 300, thereby deforming, and over time, a large cumulative error will be generated on the first film material 400 and the second film material 500, thereby affecting the transfer precision of the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500.

[0053] It can be understood that in the transfer process of the present application, the two composite rollers of the composite roller group 300 are first driven to move away from each other, wherein the transfer area is formed between the two composite rollers, 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, 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, then the two composite rollers are driven to move close to each other, so as 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 the workpiece 410 on the first film material 400 is transferred to the bonding area 510 on the second film material 500. After the composite roller group 300 composites and transfers one of the workpieces 410 on the first film material 400 to the bonding area 510 on 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 of the first film material 400 and the second film material 500 during movement, thereby reducing the deformation of the first film material 400 and the second film material 500 during movement, and further improving the transfer precision of the workpiece 410 on the first film material 400 to the bonding area 510 on the second film material 500.

[0054] In some embodiments of the present application, step S100 includes but is not limited to the following steps:

[0055] Step S110, judge that the last workpiece 410 is separated from the transfer area, drive the two composite rollers to move away from each other, so that the composite roller group 300 is switched 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 composite and transfer the workpiece 410 in the transfer area to the bonding area 510.

[0056] It should be noted that when the composite roller group 300 is in the 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 transferred and attached to the attachment area 510 of the second film material 500; when the composite roller group 300 is in the separated state, the two composite rollers of the composite roller group 300 are spaced apart by a long distance, 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 normally pass through the transfer area.

[0057] It can be understood that before the last workpiece 410 is separated from the transfer area and the next workpiece 410 enters the transfer area, the composite roller group 300 does not need to perform the composite action, but when the composite roller group 300 is in the composite state, it will affect the normal passing 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 produce a large deformation; in the transfer process of the embodiment, when the last workpiece 410 is separated from 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 is switched from the composite state to the separated state, in this case, the first film material 400 and the second film material 500 can smoothly pass through the transfer area, and the composite roller group 300 is less hindered to the first film material 400 and the second film material 500 during movement, so as to reduce the deformation of the first film material 400 and the second film material 500 during movement.

[0058] In some embodiments of the present application, with reference to Figure 2 , in step S400, the following steps are included but not limited to:

[0059] Step S410, when the current workpiece 410 enters the transfer area, the two composite rollers are driven to move close to each other, so that the composite roller group 300 is switched from the separated state to the composite state;

[0060] Step S420, keeping the composite roller group 300 in the composite state until the current workpiece 410 is completely transferred and attached to the transfer area.

[0061] 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 extrude 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 is switched from the separation state to the 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 on the second film material 500.

[0062] In some embodiments of the present application, with reference to Figure 3 , the interval L1 between any two adjacent workpieces 410 on the first film material 400, the moving speed V1 of the first film material 400, and the following steps in step S410, but not limited to:

[0063] Step S411, timing starts from the time when the previous workpiece 410 leaves the transfer area, and when the preset time T is reached, it is determined that the current workpiece 410 enters the transfer area, wherein the preset time satisfies: T = L1 / V1.

[0064] It can be understood that after the preset time T, the leading 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 be switched 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 on the second film material 500.

[0065] In some embodiments of the present application, with reference to Figure 3 and Figure 4 , each workpiece 410 on the first film material 400 is arranged with an interval L2 along the extension direction of the first film material 400, each bonding area 510 on the second film material 500 is arranged with an interval L3 along the extension direction of the second film material 500, and the moving speed V2 of the second film material 500, the moving speed of the first film material 400 and the moving speed of the second film material 500 satisfy: V1 / V2 = L2 / L3.

[0066] 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 = L2 / L3, 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, so that the workpiece 410 on the first film material 400 can be accurately transferred to the bonding area 510 on the second film material 500.

[0067] Next, with reference to Figure 5 the transfer device of the second aspect of the present application is described in detail.

[0068] According to the second aspect of the present application, the transfer device is used to implement the transfer process of the first aspect of the present application.

[0069] In some embodiments of the present application, referring to Figure 5 , the transfer device comprises a composite assembly 10, a first pulling assembly and a second pulling assembly. The composite assembly 10 comprises a driving structure 100, a mounting frame 200 and a composite roller set 300. The composite roller set 300 forms a transfer area between two composite rollers. The driving structure 100 is arranged on the mounting frame 200 and connected to at least one of the composite rollers. The driving structure 100 is used to drive the composite rollers to move closer to or away from the transfer area. The first pulling assembly is arranged on one side of the composite assembly 10 and used to pull the first film material 400 through the transfer area. The second pulling assembly is arranged on one side of the composite assembly 10 and used to pull the second film material 500 through the transfer area.

[0070] For example, as shown in Figure 5 , the composite assembly 10 comprises a driving structure 100, a mounting frame 200 and a composite roller set 300. The composite roller set 300 comprises two composite rollers arranged in a vertical direction and extending in a left-right direction. The transfer area is formed between the two composite rollers. The driving structure 100 is arranged on the mounting frame 200 and connected to at least one of the composite rollers.

[0071] It can be understood that under the pulling of the first pulling assembly, the first film material 400 can move from front to back to pass through the transfer area. Under the pulling of the second pulling assembly, 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 transfer area 510 on the second film material 500 both enter the transfer area, the driving structure 100 can drive the two composite rollers to move closer to each other, so that the composite roller set 300 switches from the separation state to the composite state. At this time, the composite roller set 300 can successfully composite and transfer the workpiece 410 on the first film material 400 to the transfer area 510 on the second film material 500. When the workpiece 410 on the first film material 400 and the transfer area 510 on the second film material 500 both 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 set 300 switches from the composite state to the separation state. At this time, the two composite rollers of the composite roller set 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 backward under the pulling of the first pulling assembly and the second pulling assembly, respectively.

[0072] In further embodiments of the present application, the two composite rollers are a first composite roller 310 and a second composite roller 320, the second composite roller 320 is rotatably arranged on the mounting frame 200, a sliding block 210 is slidably arranged on the mounting frame 200 in the vertical direction, the first composite roller 310 is rotatably arranged on the sliding block 210, and the driving structure 100 comprises a driver 110 and a transmission structure 120, the driver 110 is connected with the sliding block 210 through the transmission structure 120, and the driver 110 can drive the sliding block 210 to move up and down through the transmission structure 120.

[0073] For example, as shown in Figure 5 , the two composite rollers are distributed in the vertical direction, wherein the composite roller on the upper side is the first composite roller 310, and the composite roller on the lower side is the second composite roller 320, the second composite roller 320 is rotatably arranged on the mounting frame 200, the mounting frame 200 is provided with the sliding block 210, the sliding block 210 is slidably arranged in the vertical direction, the first composite roller 310 is rotatably arranged on the sliding block 210, and the driving structure 100 comprises a driver 110 and a transmission structure 120, the driver 110 is arranged on the mounting frame 200, and the output end of the driver 110 is in transmission connection with the sliding block 210 through the transmission structure 120.

[0074] It can be understood that under the driving of the driver 110, the transmission structure 120 can drive the sliding block 210 to move up and down, so that the sliding block 210 can drive the first composite roller 310 to move closer to or 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 separated state.

[0075] In some embodiments of the present application, referring to Figure 5 , the transmission structure 120 comprises a transmission plate 121 and a transmission rod 122, the transmission rod 122 is arranged in extension in the vertical direction, the transmission rod 122 is connected with the sliding block 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 for abutting with the upper plate surface of the transmission plate 121, the second abutting protrusion 122b is used for abutting with the lower plate surface of the transmission plate 121, the driver 110 is connected with the transmission plate 121, and is used for driving the transmission plate 121 to move up and down.

[0076] 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 and push the first abutting 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 sliding block 210 and the first composite roller 310 to move upward, and the composite roller set 300 is switched 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 and push the second abutting 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 sliding block 210 and the first composite roller 310 to move downward, and the composite roller set 300 is switched from the separated state to the composite state.

[0077] In further embodiments of the present application, with reference to Figure 5 , the distance between the first abutting protrusion 122a and the second abutting protrusion 122b is greater than the thickness of the transmission plate 121 in the vertical direction; the mounting frame 200 is further provided with an elastic connecting piece 220, the elastic connecting piece 220 is connected with the sliding block 210 and the mounting frame 200 respectively, and the elastic connecting piece 220 is used to provide an elastic force for keeping the first composite roller 310 close to the second composite roller 320.

[0078] It can be understood that since the elastic connecting piece 220 is connected with the sliding block 210 and the mounting frame 200 respectively, and the elastic connecting piece 220 is used to provide an elastic force for keeping the first composite roller 310 close to the second composite roller 320, and then when the composite roller set 300 is in the composite state, the elastic connecting piece 220 can keep the first composite roller 310 close to the second composite roller 320, so that the composite roller set 300 can smoothly composite and transfer the workpiece 410 on the first film material 400 into the bonding area 510 of the second film material 500.

[0079] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
