[0002] Flexible Printed Circuit (FPC) has the characteristics of high wiring density, light weight, thin thickness, good bendability, etc. It is widely used in electronic components. During its production process, the flexible circuit board needs to be coated to protect the flexible circuit board from damage.

[0003] During the production of flexible circuit boards, multiple layers of copper tapes need to be bonded together to form different conductive layers. During the production of existing multi-layer copper tapes, a layer such as Figure 6 As shown, there are multiple adhesive film sheets, and a protective film is reserved on the surface of the adhesive film sheet. When pasting the surface copper tape, the protective film on the adhesive film sheet needs to be torn off first. At present, it is difficult to realize continuous film peeling in the continuous production process of multi-layer copper tapes, resulting in low production efficiency.

[0004] Therefore, we need to design a roll-to-roll double-sided copper machine tape mechanism to solve these problems. Summary of the invention

[0045] The pasting mechanism includes a mounting plate 18, on which a material rack 19, a rolling and pasting assembly, a shearing assembly and a detection sensor 28 are arranged;

[0046] The rolling assembly includes a swing arm 20, a swing arm cylinder 24, a suction belt disc 36, and a rolling wheel 25. One end of the swing arm 20 is hinged to the mounting plate 18.

[0048] The detection sensor 28 is arranged on the mounting plate 18 on one side of the press-shear cylinder 27 .

[0049] like Figure 2As shown, the driving mechanism includes a driving motor 2, a slide rail 16, a slider 17, a ball screw 14 and a screw nut seat 15. A driving wheel 3 is fixedly provided at the output end of the driving motor 2. There are two slide rails 16 and two ball screws 14, which are respectively fixedly provided on the main frame 1 on both sides of the bracket 21. The slider 17 is slidably provided on the slide rail 16. The screw nut seat 15 is sleeved on the ball screw 14. The mounting plate 18 is fixedly connected to the slider 17 and the screw nut seat 15. A synchronous wheel 5 is fixedly provided at one end of the ball screw 14. The two synchronous wheels 5 are sleevedly connected by a synchronous belt 6, and one of the synchronous wheels 5 is sleevedly connected to the driving wheel 3 by a driving belt 4. In this arrangement, the slider 17 and the slide rail 16 can be used to support the mounting plate 18 and guide the sliding direction. The movement of the mounting plate 18 can be controlled by the screw nut seat 15, the ball screw 14 and the driving motor 2.

[0050] Specifically, a connecting base plate 8 and a pressing base plate 9 are fixedly provided on the main frame 1 on one side of the bracket 21, a clamping plate 10 is provided between the pressing base plate 9 and the connecting base plate 8, a clamping cylinder 11 is fixedly provided on the connecting base plate 8, and the output end of the clamping cylinder 11 is fixedly connected to the clamping plate 10. Such a configuration can fix the copper tape 41 when the tape 40 is pasted.

[0051] Specifically, a limit switch 33 is fixedly provided on the main frame 1, and a trigger piece 42 is fixedly provided on the mounting plate 18. The trigger piece 42 matches the output end of the limit switch 33. Such a setting can limit the moving position of the mounting frame to avoid collision.

[0052] Specifically, a tensioning wheel 7 is rotatably provided on the main frame 1 , and a side wall of the tensioning wheel 7 is in contact with the synchronous belt 6 . Such a setting can adjust the tension of the synchronous belt 6 .

[0053] like Figure 1 and Figure 4 As shown, there are two groups of pasting mechanisms, and the two groups of pasting mechanisms are symmetrically distributed along the bracket 21. Such an arrangement can process both sides of the copper strip 41 at the same time.

[0054] Specifically, a pressing and shearing wheel 26 is rotatably provided at the output end of the pressing and shearing cylinder 27 . Such a configuration can make the adhesive tape 40 tensioned when cutting the adhesive tape 40 , thereby facilitating the cutting operation of the scissors 31 .

[0055] Specifically, an idler wheel 38 and a material blocking rod 39 are rotatably mounted on the swing arm 20 , and a support block 37 is provided at the output end of the suction belt disk 36 , so that the adhesive belt 40 can be fixed.

[0056] Specifically, a reset spring 23 is also provided on the mounting plate 18, and the free end of the reset spring 23 is connected to the swing arm 20. The reset spring 23 is arranged in this way to ensure that the rolling wheel 25 on the swing arm 20 can be separated from the copper tape 41 without sticking the tape 40.

[0057] like Figure 3 As shown, a transverse slide 32 is fixedly provided at the output end of the transverse cylinder 29, and the shearing cylinder 30 is fixedly provided on the transverse slide 32. A mounting seat 34 is also fixedly provided on the transverse slide 32. The scissors 31 are detachably mounted on the mounting seat 34. The output end of the shearing cylinder 30 is connected to the scissors 31 through an elastic pressure head 35. Such an arrangement enables the scissors 31 and the shearing cylinder 30 to be installed and fixed using the transverse slide 32.

[0058] The working process of this embodiment is as follows: during operation, the adhesive tape 40 is first installed on the material rack 19, and then the end of the adhesive tape 40 is passed between the idle wheel 38 and the material blocking rod 39, and then the end of the adhesive tape 40 is passed between the suction disk 36 and the support block 37. In this process, the uncoated side of the adhesive tape 40 is brought into contact with the idle wheel 38 and the suction disk 36, and finally the uncoated side of the adhesive tape 40 is attached to the rolling wheel 25 again.

[0059] At this time, the telescopic rod of the clamping cylinder 11 is in a retracted state, driving the clamping rod close to the pressing bottom plate 9, and the telescopic rod of the swing arm cylinder 24 is also in a retracted state, driving the free end of the swing arm 20 to move upward. At the same time, the suction force generated by the suction disk 36 will adsorb the tape 40 to the inner wall of the suction disk 36, and the transverse cylinder 29, the shearing cylinder 30 and the pressing and shearing cylinder 27 are all in a retracted state.

[0060] When the copper tape 41 is pasted, the unwound middle copper tape 41 passes between the connecting bottom plate 8 and the clamping rod on the main frame 1, and then passes the middle copper tape 41 through the bracket 21. When the protective films on the surfaces of two adjacent adhesive films on the middle copper tape 41 need to be connected by the adhesive tape 40, when the joint of the two adhesive films moves to the bottom of the swing arm 20, the clamping cylinder 11 will output, so that the telescopic rod pushes the clamping plate 10 upward, so that the clamping plate 10 is close to the connecting bottom plate 8, the middle copper tape 41 is fixed, and then the swing arm cylinder 24 pushes the swing arm 20 to the bracket 21. The frame 21 approaches, pushing the adhesive surface of the tape 40 on the swing arm 20 that is in contact with the rolling wheel 25 to contact the protective film on the copper belt 41, and then the driving motor 2 will drive the driving wheel 3 to rotate, and the synchronous wheel 5 connected to the driving wheel 3 through the driving belt 4 will start to rotate, and the other synchronous wheel 5 will also rotate driven by the synchronous belt 6, so that the two ball screws 14 rotate synchronously, and the mounting plate 18 is driven to move through the screw nut seat 15. When the mounting plate 18 moves, the tape 40 will be adhered to the protective film joints on two adjacent adhesive film pieces on the copper belt 41 through the rolling wheel 25 on the swing arm 20.

[0061] When the adhesive tape 40 is pasted, the driving motor 2 will stop rotating, and then the shearing cylinder 27 will drive the extension, so that the shearing wheel 26 contacts the pasted adhesive tape 40, and then the swing arm cylinder 24 will shorten and drive the swing arm 20 to move upward, and when the swing arm 20 moves upward, the push block will drive the adhesive tape 40 to move upward, so that the adhesive tape 40 is in a tilted and tight state between the rolling wheel 25 and the shearing wheel 26, and then the transverse cylinder 29 will output, drive the transverse slide 32 to move, and push the scissors 31 out through the mounting seat 34 on the transverse slide 32, and after the scissors 31 are pushed out, the adhesive tape 40 between the rolling wheel 25 and the shearing wheel 26 is in the blade of the scissors 31, and then the shearing cylinder 30 will output, push the blade of the scissors 31 to close and cut the adhesive tape 40, and then the shearing cylinder 30 will shorten, so that the blade of the scissors 31 is opened, and then the transverse cylinder 29 will retract, and drive the scissors 31 to reset through the transverse slide 32.

[0062] Then the pressing and shearing cylinder 27 will retract to drive the pressing and shearing wheel 26 to separate from the adhesive tape 40, and then the driving motor 2 will rotate in the opposite direction, causing the ball screw 14 to rotate in the opposite direction, driving the pasting mechanism to move in the opposite direction and reset, so as to facilitate the pasting of the adhesive tape 40 again.

[0063] During the pasting process of the tape 40, the detection sensor 28 will detect the pasting status of the tape 40. The detection sensor 28 is a color sensor. Therefore, in order to facilitate the detection of the status of the tape 40, the color of the tape 40 is different from the color of the film sheet. Therefore, if there is a leak during the pasting process, the detection sensor 28 will detect the lack of color of the tape 40 and then issue a warning. At the same time, if the tape 40 is used up, it will also issue a warning to facilitate the staff to replace the tape 40.

[0064] In this embodiment, an oil collecting plate 13 is installed at the bottom of the ball screw 14 above the copper belt 41, which can collect the lubricating oil dripping on the ball screw 14 to prevent the lubricating oil from dripping onto the copper belt 41 and causing contamination of the copper belt 41, thereby affecting the production quality of the copper belt 41; and a dust cover 22 is also installed on the outside of the driving belt 4 and the synchronous belt 6; and the air pipe connected to the cylinder on the mounting plate 18 and some wires are stored by the drag chain 12, which can prevent the air pipe or wire from being squeezed and broken when the mounting plate 18 moves, thereby protecting the air pipe and wires.

[0065] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
