[0002] With the development of science and technology, automated placement has replaced manual placement, and the manufacturing industry has transformed into intelligent manufacturing, which has led to the need for various electronic auxiliary materials and components to be designed to meet the conditions of automated equipment. Conductive foam needs to be changed from sheets to automated coils due to the influence of product length and product characteristics. Currently, the same industry uses manual placement or placement machines for placement. This method cannot improve speed and efficiency, and the production cost is high. Most importantly, it is easy to cause foam scratches during the process of manual placement or placement machines. In order to solve the above problems, the present application designs a device that die-cuts long foam strips into short foam strips and rolls them up based on a carrier film. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention discloses a conductive foam jump cutting device and a jump cutting process thereof.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] Example

[0033] In order to solve the problem that the foam is pasted manually or by a patch machine in the prior art and then rolled up by a carrier film, reference is made to Figure 1-Figure 3 As shown, the present application discloses a conductive foam jump cutting device, including an asynchronous feeding mechanism 10, a typesetting jig 20, a die-cutting mechanism 30, a first carrier film unloading mechanism 40, a second carrier film unloading mechanism 50, a waste material rewinding mechanism 60 and a finished product rewinding mechanism 70;

[0034] The first carrier film discharge mechanism 40 is used to release the first carrier film and hold a plurality of long foam strips to move through the typesetting jig 20 to the die-cutting mechanism 30;

[0035] The asynchronous feeding mechanism 10 is used to pull the first carrier film forward to the inside of the die-cutting mechanism 30 and / or to pull the first carrier film backward to move a set distance;

[0036] The waste material rewinding mechanism 60 rewinds the waste material of the carrier film released by the first carrier film unwinding mechanism 40 inside the die-cutting mechanism 30;

[0037] The second carrier film discharge mechanism 50 is used to release the second carrier film to pass through the die-cutting mechanism 30 to support a plurality of short foam strips after die-cutting;

[0038] The finished product rolling mechanism 70 is used for rolling up the second carrier film supporting a plurality of short foam strips.

[0039] In one of the specific embodiments, the typesetting jig 20 of the present application is provided with a hollow portion 21 for allowing a plurality of long foam strips and a first supporting film to pass through. A plurality of square grooves 22 are provided on one side of the starting end of the plate along its width direction to form a plurality of square teeth 23. The plurality of square teeth 23 correspond to the spacing formed by the plurality of long foam strips. When the first supporting film moves forward or backward, the plurality of long foam strips will be able to be positioned and moved, and have a better use effect.

[0040] In one specific embodiment, the die-cutting mechanism 30 of the present application includes an upper die base 31 and a lower die base 32. The upper die base 31 is driven to rise and fall by an external lifting drive source. The bottom of the upper die base 31 is provided with a die-cutting tool 33 for cutting a plurality of long foam strips. It should be noted here that the external lifting drive source of the present application is preferably a hydraulic cylinder (not shown in the present application). Driven by the lifting drive source, the lower die base 32 of the present application descends together with the die-cutting tool 33. In this way, the die-cutting tool 33 can die-cut a plurality of long foam strips.

[0041] In one specific embodiment, the asynchronous feeding mechanism 10 of the present application includes an upper round roller 11 driven by a forward and reverse motor 13, and rotating rollers 12 are respectively provided on both sides above the upper round roller 11, which press the first carrier film and cooperate with the upper round roller 11. When the forward and reverse motor 13 drives the upper round roller 11 to rotate forward, the two rotating rollers 12 will cooperate with the upper round roller 11 to move the first release film forward. Conversely, when the forward and reverse motor 13 drives the upper round roller 11 to reverse, the two rotating rollers 12 will cooperate with the upper round roller 11 to move the first release film in the reverse direction. It should be emphasized here that the first carrier film of the present application must move in the reverse direction after die-cutting the short strips of foam, so as to avoid scratching the rolled-up short strips of foam, thereby effectively protecting the foam.

[0042] In a preferred embodiment, the first carrier film unloading mechanism 40, the waste winding mechanism 60, the second carrier film unloading mechanism 50 and the finished product winding mechanism 70 of the present application are all magnetic powder brakes. This structure is a known technology and the present application will not elaborate on it here.

[0043] In order to guide the first carrier film, the present application provides a first guide roller 80 for guiding the first carrier film outside the die-cutting mechanism 30 .

[0044] In order to guide the waste of the first carrier film, the present application further provides a second guide roller 90 for guiding the waste of the first carrier film below the upper round roller 11 .

[0045] In addition to the above structure, the present application also claims to protect a conductive foam jump cutting process, and the working principle of the conductive foam jump cutting device claimed to be protected by the present application can also refer to the following steps, S100: the first carrier film discharge mechanism 40 releases the first carrier film to hold a number of long foam strips and pass through the hollow portion 21 of the typesetting fixture 20 and the upper round roller 11 and two rotating rollers 12 of the asynchronous feeding mechanism 10 to between the upper die seat 31 and the lower die seat 32 of the die-cutting mechanism 30, the waste winding mechanism 60 will pre-wind up part of the first carrier film waste released by the first carrier film discharge mechanism 40; the finished product winding mechanism 70 will pre-select and wind up part of the second carrier film released by the second carrier film discharge mechanism 50;

[0046] S200: the asynchronous feeding mechanism 10 pulls the first carrier film forward so that a plurality of long foam strips with a set length are located on the second carrier film. At the same time, the first carrier film waste winding mechanism 60 will wind up the generated carrier film;

[0047] S300: The lifting drive source drives the upper die holder 31 to descend so that the die-cutting tool 33 cooperates with the lower die holder 32 to die-cut short foam strips of a set length from a plurality of long foam strips onto the second carrier film;

[0048] S400: When the lifting drive source drives the upper die seat to rise to a set height, the asynchronous pulling mechanism pulls the first carrier film to move backward to a set length, and at the same time, the second carrier film unwinding mechanism 50 unwinds the second carrier film of a set length and synchronously rewinds it through the finished product rewinding mechanism 70;

[0049] S500: The asynchronous feeding mechanism 10 pulls the first carrier film forward by the length in S200 and adds the length pulled backward by the asynchronous pulling mechanism in S400 so that a plurality of long foam strips with a set length are again located on the second carrier film. At the same time, the first carrier film waste winding mechanism 60 will wind up the generated carrier film, and thereafter, it will run continuously according to the actions after S300.
