Description

Technical Field

[0001] The present application relates to the technical field of conductive foam production equipment, and in particular to an asynchronous laminator. Background Art

[0002] Conductive foam is a special material. By covering a flame-retardant sponge with conductive cloth and through treatment, it is given excellent surface conductivity. Conductive foam can be easily fixed on electronic components that require electromagnetic shielding with tape and can achieve a good shielding effect. Therefore, it is widely used in communication equipment (cabinet), computers, medical equipment, satellite communication, and the aerospace field.

[0003] Currently, conductive foam is mainly produced by a molding machine in an automatic production line. After automatic fixed-length die-cutting, it becomes a finished product. However, for the convenience of using conductive foam, most customers require the conductive foam after fixed-length die-cutting to be arranged on a blank tape and shipped in rolls. Currently, mainly the conductive foam with a blue film attached to its surface is integrally adhered to the blank tape, and then the conductive foam is subjected to fixed-length die-cutting, so that the conductive foam after fixed-length die-cutting is neatly arranged on the blank tape for the convenience of customers.

[0004] In the above process, there is usually a certain distance between the conductive foams arranged on the blank tape for the convenience of customers. However, since the conductive foam is integrally adhered to the blank tape and then die-cut, there will be a certain distance between two adjacent die-cut positions on the conductive foam, resulting in a large amount of waste generated after die-cutting of the conductive foam, thereby reducing the utilization rate of the conductive foam and causing waste of the conductive foam. Summary of the Utility Model

[0005] In order to improve the utilization rate of conductive foam in the production process and thus reduce the waste of conductive foam, the present application provides an asynchronous laminator.

The elevating cylinder helps to drive the movement of the upper die, thereby driving the cutting die to perform die-cutting on the conductive foam, which helps to laminate the die-cut conductive foam onto the blank tape. And by using the fact that the feeding directions of the first feeding component and the second feeding component are opposite and the feeding speeds are different, it helps to make the feeding length of the blank tape greater than the feeding length of the conductive foam within the same time, and further helps to reduce the die-cutting interval of the conductive foam while ensuring the arrangement interval of the die-cut conductive foam on the blank tape, which helps to improve the utilization rate of the conductive foam and reduce the waste of the conductive foam.

[0014] By adopting the above technical solution, the second winding motor is used to drive the second winding roller to wind up the rolled blank material strip placed on the second unwinding roller, thereby helping to drive the blank material strip to pass between the upper mold and the lower mold and make the blank material strip abut against the lower mold, thereby facilitating the die-cut conductive foam to be bonded to the blank material strip.

[0016] By adopting the above technical solution, the feeding mechanism is used to help guide the blank material strip to enter between the upper die and the lower die, thereby helping to improve the accuracy of the position of the blank material strip entering between the upper die and the lower die, and further helping to improve the accuracy of the position where the conductive foam after die cutting is attached to the blank material strip. The traction mechanism is used to help traction the blank material strip, thereby helping to improve the movement accuracy of the blank material strip relative to the conductive foam, and further helping to improve the bonding effect of the conductive foam after die cutting on the blank material strip.

[0017] In a specific feasible implementation scheme, a fixed frame is provided on the frame, and a film removal assembly and a film sticking assembly are jointly provided on the frame and the fixed frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] An embodiment of the present application discloses an asynchronous laminating machine. Referring to Figure 1 and Figure 2 , it includes a frame 1. A die-cutting mechanism 2 is provided on the frame 1. The die-cutting mechanism 2 includes a lower die 21 which is fixedly installed on the top surface of the frame 1. A plurality of lifting cylinders 22 are also fixedly installed on the top surface of the frame 1. The plurality of lifting cylinders 22 are located on the outer periphery of the lower die 21. The output ends of the plurality of lifting cylinders 22 are commonly installed with an upper die 23. The upper die 23 is located above the lower die 21 and a cutting die 24 is fixedly installed on the surface of the upper die 23 facing the lower die 21.

[0032] Referring to Figure 1 and Figure 3, an installation frame 3 is fixedly installed on the side wall of the upper die 23. A first feeding component 4 is arranged on the installation frame 3. The first feeding component 4 includes a first unwinding roller 41, a first winding roller 42 and a first winding motor 43. The first unwinding roller 41 and the first winding roller 42 are both rotatably installed on the installation frame 3. The first winding motor 43 is fixedly installed on the installation frame 3 and is in transmission connection with the first winding roller 42. A first guiding roller 6 and a second guiding roller 7 are fixedly installed on the installation frame 3, and the first guiding roller 6 and the second guiding roller 7 are respectively located on both sides of the upper die 23.

[0033] Referring to Figure 2 and Figure 3 , an operator places the rolled conductive foam on the first unwinding roller 41. The first winding motor 43 operates to drive the first winding roller 42 to rotate, thereby winding the conductive foam on the first unwinding roller 41, so that the conductive foam passes between the upper die 23 and the lower die 21 and abuts against the upper die 23 during the winding process. When the first winding roller 42 winds the conductive foam, the first guiding roller 6 and the second guiding roller 7 help to guide the feeding path of the conductive foam and at the same time help to adjust the tension of the conductive foam.

[0034] Referring to Figure 1 and Figure 3 , a second feeding component 5 is arranged on the frame 1. The second feeding component 5 includes a feeding frame 51, a second unwinding roller 52, a winding frame 53, a second winding roller 54 and a second winding motor 55. The feeding frame 51 is fixedly installed on one side wall of the frame 1. The second unwinding roller 52 is rotatably installed on the feeding frame 51. The winding frame 53 is fixedly installed on the side wall of the frame 1 opposite to the feeding frame 51. The second winding roller 54 is rotatably installed on the winding frame 53. The second winding motor 55 is fixedly installed on the winding frame 53 and is in transmission connection with the second winding roller 54. An inlet mechanism 8 is arranged at the position between the second unwinding roller 52 and the die-cutting mechanism 2 on the frame 1. A traction mechanism 9 is arranged at the position between the second winding roller 54 and the die-cutting mechanism 2 on the frame 1.

[0035] Referring to Figure 2 and Figure 3 , an operator places the rolled blank tape on the second unwinding roller 52. The second winding motor 55 operates to drive the second winding roller 54 to rotate, thereby winding the blank tape on the second unwinding roller 52, so that the blank tape passes between the upper die 23 and the lower die 21 and abuts against the lower die 21 during the winding process.

[0036] Referring to Figure 2 and Figure 3, when both the conductive foam and the blank tape pass through between the upper die 23 and the lower die 21, the output ends of the multiple lifting cylinders 22 contract, driving the upper die 23 and the cutting die 24 to move downward, thereby using the cutting die 24 to die-cut the conductive foam, and at the same time helping to drive the die-cut conductive foam to adhere to the blank tape. Since the moving speed of the conductive foam is greater than that of the blank tape, the feeding length of the blank tape within the same time is greater than that of the conductive foam, which helps to reduce the die-cut interval of the conductive foam while ensuring the arrangement interval of the die-cut conductive foam on the blank tape, helps to improve the utilization rate of the conductive foam, and reduces the waste of the conductive foam.

[0037] Refer to Figure 2 and Figure 3 , before the blank tape enters between the upper die 23 and the lower die 21, the feeding mechanism 8 helps to guide the blank tape to the position between the upper die 23 and the lower die 21, which helps to improve the accuracy of the blank tape entering the position between the upper die 23 and the lower die 21, and further helps to improve the accuracy of the position where the die-cut conductive foam adheres to the blank tape. After the die-cut conductive foam adheres to the blank tape, the traction mechanism 9 helps to traction the blank tape, which helps to improve the moving accuracy of the blank tape relative to the conductive foam, and further helps to improve the adhesion effect of the die-cut conductive foam on the blank tape.

[0038] Refer to Figure 3 , a fixing frame 10 is fixedly installed on the frame 1. The fixing frame 10 is located between the die-cutting mechanism 2 and the second winding roller 54. A film removing assembly 11 is jointly provided on the frame 1 and the fixing frame 10. The film removing assembly 11 includes a third unwinding roller 111, a third winding roller 112, a third winding motor 113 and a pressure roller 114. The third unwinding roller 111 and the third winding roller 112 are both rotatably installed on the fixing frame 10. The third winding motor 113 is fixedly installed on the fixing frame 10 and is in transmission connection with the third winding roller 112. The pressure roller 114 is rotatably installed on the top surface of the frame 1.

[0039] Refer to Figure 3 , the operator places the tape on the third unwinding roller 111. When the blank tape with the conductive foam adhered passes under the pressure roller 114, the third winding motor 113 operates to wind the tape placed on the third unwinding roller 111, so that the tape is wound and passes under the pressure roller 114 together with the blank tape during the winding process, and the tape is separated from the blank tape after passing through the pressure roller 114, which helps to remove the blue film on the surface of the conductive foam on the blank tape.

[0040] Refer to Figure 3, a film pasting assembly 12 is jointly arranged on the frame 1 and the fixing frame 10. The film pasting assembly 12 includes a fourth unwinding roller 121 and a laminating roller 122. The fourth unwinding roller 121 is rotatably installed on the fixing frame 10, and the laminating roller 122 is rotatably installed on the top surface of the frame 1. An operator places the protective film on the fourth unwinding roller 121. After the blue film on the surface of the conductive foam on the blank tape is removed, the operator pastes the protective film on the surface of the blank tape and the conductive foam, and as the blank tape moves, the blank tape and the protective film jointly pass through the laminating roller 122, so that the protective film adheres to the surface of the blank tape and the conductive foam, playing a protective role for the conductive foam.

[0041] The implementation principle of the embodiment of the present application is as follows: An operator places the rolled conductive foam on the first unwinding roller 41, and the first winding motor 43 operates to drive the first winding roller 42 to rotate, thereby winding the conductive foam on the first unwinding roller 41, so that the conductive foam passes between the upper die 23 and the lower die 21 and abuts against the upper die 23 during the winding process. When the first winding roller 42 winds the conductive foam, the first guide roller 6 and the second guide roller 7 help to guide the feeding path of the conductive foam and at the same time help to adjust the tension of the conductive foam.

[0042] An operator places the rolled blank tape on the second unwinding roller 52, and the second winding motor 55 operates to drive the second winding roller 54 to rotate, thereby winding the blank tape on the second unwinding roller 52, so that the blank tape passes between the upper die 23 and the lower die 21 and abuts against the lower die 21 during the winding process.

[0043] When both the conductive foam and the blank tape pass between the upper die 23 and the lower die 21, the output ends of the plurality of lifting cylinders 22 contract, driving the upper die 23 and the cutting die 24 to move downward, thereby using the cutting die 24 to die-cut the conductive foam and at the same time helping to drive the die-cut conductive foam to adhere to the blank tape. Since the moving speed of the conductive foam is greater than the moving speed of the blank tape, the feeding length of the blank tape in the same time is greater than the feeding length of the conductive foam, which helps to reduce the die-cut interval of the conductive foam while ensuring the arrangement interval of the die-cut conductive foam on the blank tape, helps to improve the utilization rate of the conductive foam, and reduces the waste of the conductive foam.

[0044] An operator places the tape on the third unwinding roller 111. When the blank tape with the conductive foam adhered passes under the pressure roller 114, the third winding motor 113 operates to wind the tape placed on the third unwinding roller 111, so that the tape passes under the pressure roller 114 together with the blank tape during the winding process, and the tape separates from the blank tape after passing through the pressure roller 114, which helps to remove the blue film on the surface of the conductive foam on the blank tape.

[0045] The operator places the protective film on the fourth unwinding roller 121. After the blue film on the surface of the conductive foam on the blank tape is removed, the operator attaches the protective film to the surfaces of the blank tape and the conductive foam, and as the blank tape moves, the blank tape and the protective film jointly pass through the laminating roller 122, so that the protective film adheres to the surfaces of the blank tape and the conductive foam, playing a protective role for the conductive foam.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
