Technical Field

[0001] This utility model relates to the field of copper clad laminate production technology, specifically to a continuous cutting machine for copper clad laminate production with an anti-adhesion structure. Background Technology

[0002] Copper-clad laminate (CCL) is a sheet-like material produced by hot pressing and is used as a basic material in circuit board manufacturing. During the production process, a continuous cutting machine is needed to punch and cut the CCL into different shapes. However, the continuous cutting machines currently on the market for CCL production still have the following problems:

[0003] When copper-clad laminates need to be stamped and cut into shapes of different diameters, continuous stamping and cutting can easily cause the round copper-clad laminates to stick to the inside of the cutting tool, thus affecting subsequent continuous processing and reducing the processing efficiency of the copper-clad laminate production process.

[0004] To address the aforementioned issues, an innovative design was implemented based on the existing continuous cutting machine used for copper clad laminate production. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous cutting machine for copper clad laminate production with an anti-adhesion structure, so as to solve the problem mentioned in the background art that the continuous cutting machines for copper clad laminate production commonly found on the market, when needing to punch and cut copper clad laminates into shapes of different diameters, perform continuous punching and cutting work as a whole, which easily causes the processed circular copper clad laminates to stick to the inside of the cutting tool, thereby affecting subsequent continuous processing and reducing the processing efficiency in the copper clad laminate production process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous cutting machine for copper-clad laminate production with an anti-adhesion structure, comprising a stamping base and a hydraulic lifting rod.

[0008] Preferably, the lifting square frame and the combined straight plate are integrated into a single structure, and the combined straight plates are evenly distributed on the lifting square frame. The lifting square frame is connected to the connecting frame by welding.

[0009] Preferably, the stamping and cutting tool and the combination joint are integrated into one structure, and the combination joint and the combination hole are connected by a threaded connection, and the combination holes are evenly distributed on the combination plate.

[0012] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a continuous cutting machine for copper-clad laminate production with an anti-adhesion structure, including a stamping base 1 and a hydraulic lifting rod 6. The top surface of the stamping base 1 has a positioning hole 2, and a limit strip 3 is installed above the stamping base 1. A positioning connector 4 is provided at the bottom end of the limit strip 3, and the positioning connector 4 is located inside the positioning hole 2. A support frame 5 is welded and fixedly installed on the rear side of the middle section of the stamping base 1, and a hydraulic lifting rod 6 is fixedly installed at the front end of the top of the support frame 5. The bottom end of the hydraulic lifting rod 6 is inlaid with... A connecting frame 7 is fixedly installed, and a lifting square frame 8 is installed at the bottom of the connecting frame 7. A combined straight plate 9 is provided inside the lifting square frame 8, and a combination hole 10 is opened on the combined straight plate 9. A stamping and cutting tool 11 is installed below the combined straight plate 9, and a combination joint 12 is provided at the center of the top surface of the stamping and cutting tool 11. The combination joint 12 is connected to the combination hole 10. A return spring 13 and a pusher ball 14 are installed inside the stamping and cutting tool 11, and the pusher ball 14 is located below the return spring 13.

[0023] The positioning holes 2 are symmetrically distributed at equal intervals on the stamping base 1, and the positioning holes 2 are connected to the positioning connector 4 by a snap-fit ​​connection. The positioning connector 4 and the limiting strip 3 are integrated into one structure. The limiting strip 3 can be installed in different positions by the distribution of the positioning holes 2 on the stamping base 1 and the snap-fit ​​between the positioning connector 4 and the positioning holes 2, and can be flexibly adjusted according to the copper clad laminate of different widths.

[0024] The lifting square frame 8 and the combined straight plate 9 are integrated into one structure, and the combined straight plate 9 are evenly distributed on the lifting square frame 8. The lifting square frame 8 and the connecting frame 7 are connected by welding. The connecting frame 7 can drive the lifting square frame 8 and the combined straight plate 9 to perform synchronous lifting and lowering work, thereby driving the subsequent assembled stamping and cutting tool 11 to perform lifting and stamping.

[0025] The stamping sleeve cutting tool 11 and the combination joint 12 are integrated into one structure. The combination joint 12 is connected to the combination hole 10 by a threaded connection. The combination holes 10 are evenly distributed on the combination straight plate 9. The stamping sleeve cutting tool 11 can be fixedly installed under the combination straight plate 9 by connecting the combination joint 12 to the combination hole 10 by a threaded connection. According to the processing hole diameter and quantity, the number of stamping sleeve cutting tools 11 installed and the corresponding inner diameter of the stamping sleeve cutting tool 11 can be matched.

[0026] The return spring 13 is fixed to the inner top surface of the stamping sleeve cutting tool 11 and the outer surface of the push ball 14 by spot welding. The diameter of the push ball 14 is smaller than the inner diameter of the stamping sleeve cutting tool 11, and the bottom surface of the push ball 14 is lower than the bottom cutting edge of the stamping sleeve cutting tool 11.

Then, according to the required hole diameter and quantity of the copper-clad laminate workpiece, the corresponding inner diameter stamping and cutting tool 11 and the corresponding number of stamping and cutting tools 11 are matched. The stamping and cutting tools 11 can be threaded and fixed to the combination holes 10 on the combination straight plate 9 through the combination joint 12. After the stamping and cutting tools 11 are installed in sequence, the hydraulic lifting rod 6 on the support frame 5 can be activated. The hydraulic lifting rod 6 can drive the combination straight plate 9 and the stamping and cutting tools 11 to descend through the connecting frame 7 and the lifting square frame 8, so that the copper-clad laminate can be moved to the stamping base 1 in advance. Above and between the limiting strip 3, the stamping and cutting tool 11 performs stamping and cutting work on the copper-clad laminate. The processed circular copper-clad laminate is pressed into the stamping and cutting tool 11, squeezing the pusher ball 14. The pusher ball 14 pushes the return spring 13 to retract. Subsequently, the hydraulic lifting rod 6 drives the stamping and cutting tool 11 to rise, releasing the pressure. The pusher ball 14 can be pushed by the elastic force of the return spring 13 to automatically push out the workpiece pressed into the stamping and cutting tool 11, avoiding adhesion. The copper-clad laminate can be continuously and quickly stamped and cut. The hydraulic lifting rod 6 is a known and existing technology in the market, and will not be described in detail here. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
