Description

Technical Field

[0001] The utility model relates to the technical field of copper clad plate production, in particular to a pressing machine for aluminum-based copper clad plates. Background Art

[0002] Copper clad laminate is a plate-like material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing. It is referred to as copper clad laminate. Copper clad laminate is mainly used in the manufacture of printed circuit boards and is widely used in mobile phones, computers, televisions and other fields. Aluminum-based copper clad laminate is used as the substrate material in the manufacture of printed circuit boards. Aluminum-based copper clad laminate has the characteristics of ultra-thinness and good flexibility. It is suitable for interconnection, conduction, insulation and support of printed circuit boards, and affects the transmission speed, energy loss and characteristic impedance of signals in the circuit.

[0003] In the later stages of the preparation of copper clad laminates, hot pressing operations are required to allow the prepreg, adhesive layer, copper foil and other multi-layer structures to finally bond and solidify together. When the existing equipment is performing hot pressing operations, the glue will overflow onto the hot pressing table, thereby affecting the subsequent hot pressing of the copper clad laminates. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pressing machine for aluminum-based copper-clad laminates, which is convenient for ensuring the quality of hot pressing.

[0005] The technical solution of the present utility model is: a pressing machine for aluminum-based copper-clad laminates, comprising a laminating and forming mechanism and feeding modules respectively arranged at the ends of the laminating and forming mechanism, the laminating and forming mechanism comprising a machine base, a hot pressing seat, a lifting assembly arranged on the hot pressing seat, a lower pressing plate arranged at the output end of the lifting assembly and a heating plate arranged on the machine base, the heating plate is correspondingly arranged below the lower pressing plate, the heating plate and the lower pressing plate are both provided with heating units, the machine base is provided with degumming grooves around the heating plate, and a degumming assembly is provided on the outer periphery of the lower pressing plate.

[0006] It can be seen from the above scheme that the lifting assembly is used to drive the lower pressure plate to press down, and the lower pressure plate performs hot pressing on the copper clad laminate. The corresponding heating plate and the lower pressure plate help to fully hot press the copper clad laminate. The degumming assembly is used to remove the glue around the copper clad laminate, and the degumming groove is used to collect the removed residual glue.

[0007] The lifting assembly includes a hydraulic cylinder and a mounting plate. The hydraulic cylinder is connected to the hot pressing seat. The lower pressing plate is connected to the output end of the hydraulic cylinder via the mounting plate. The lower pressing plate is arranged at the bottom of the mounting plate. The mounting plate is slidably mounted on the hot pressing seat via a guide assembly. It can be seen that the hydraulic cylinder is used to drive the mounting plate to descend, thereby driving the lower pressing plate to press downward for hot pressing. The guide assembly is used to guide the lower pressing plate during its up and down movement.

[0008] The guide assembly includes guide posts disposed at the four corners of the base, the mounting plate being slidably connected to the guide posts via guide sleeves, the guide sleeves being provided with through holes adapted to fit the guide posts, and the guide posts being disposed on the outside of the heating plate. Thus, the guide posts pass through the through holes of the guide sleeves, and the guide sleeves are slidably connected to the guide posts to guide the lower plate on the outside of the heating plate.

[0009] The heating unit is an electric heating wire, and a thermal insulation layer is provided between the lower pressing plate and the mounting plate, as well as between the heating plate and the machine base. Therefore, the electric heating wires on both the heating plate and the lower pressing plate are used to provide a heat source on both the upper and lower sides of the copper-clad laminate, ensuring stable and consistent hot pressing and improving the hot pressing quality of the copper-clad laminate.

[0010] The feeding module includes a feeding seat and a plurality of feeding rollers arranged on the feeding seat. It can be seen that the feeding rollers rotate on the feeding seat to realize the conveying and feeding of the copper clad laminate.

[0011] The degumming assembly includes a degumming motor, a degumming mount, and a degumming knife mounted on the degumming mount. The degumming mount is connected to the output end of the degumming motor via a mounting slot. The degumming motor is mounted on the bottom of the mounting plate. A locking member is provided on the side of the degumming mount, and a guide ramp is provided on the outer side of the degumming knife. The degumming knife is detachably connected to the degumming mount via the locking member. The guide ramp facilitates the retention of excess glue after it is cut off, preventing excess glue from accumulating on the blade of the degumming knife and affecting the next degumming operation.

[0012] The scraper is provided in the glue removal tank, and the scraper is provided with a scraping surface adapted to the guide bevel. It can be seen that the scraper is used to cooperate with the glue removal knife to scrape, and the overflow glue attached to the guide bevel on the glue removal knife is centrally cleaned by the scraper to the overflow glue in the glue removal tank.

In this embodiment, the hot pressing seat 2 and the lower pressing plate 4 are adapted to the size of the copper-clad laminate, the degumming assembly 7 is arranged corresponding to the degumming groove 6, and the machine base 1 is provided with a cleaning port 10 connected to the degumming groove 6.

[0018] The lifting assembly 3 includes a hydraulic cylinder 31 and a mounting plate 32. The hydraulic cylinder 31 is connected to the hot pressing seat 2. The lower pressure plate 4 is connected to the output end of the hydraulic cylinder 31 through the mounting plate 32. The lower pressure plate 4 is arranged at the bottom of the mounting plate 32. The mounting plate 32 is slidably arranged on the hot pressing seat 2 through a guide assembly.

[0019] The guide assembly includes guide columns 33 arranged at the four corners of the machine base 1, and the mounting plate 32 is slidably connected to the guide columns 33 through guide sleeves 34. The guide sleeves 34 are provided with through holes 341 adapted to the guide columns 33, and the guide columns 33 are arranged on the outside of the heating plate 5.

It is convenient to scrape off the overflowing glue remaining on the guide bevel 721. As the degumming knife 72 moves downward and cuts, most of the overflowing glue is cut into the degumming tank 6, and a small part remains on the guide bevel 721. The degumming knife 72 continues to move downward and scrapes it off with the adapted scraping surface on the scraper. The detachable scraper can be removed during cleaning to clean the surface of the heating plate 5, maintain its surface flatness, and remove residual glue that may adhere to the four sides.

[0022] The glue removal component 7 includes a glue removal motor, a glue removal mounting seat 71 and a glue removal knife 72 arranged on the glue removal mounting seat 71. The glue removal mounting seat 71 is connected to the output end of the glue removal motor. The glue removal motor is arranged at the bottom of the mounting plate 32. A locking member 73 is arranged on the side of the glue removal mounting seat 71.

[0023] The working process of the present invention is as follows: after bonding, the copper clad laminate is fed onto the heating plate through the feed roller 12, the hydraulic cylinder 31 drives the mounting plate 32 to press down, and the guide sleeve 34 slides along the guide column 33 to achieve guidance, and the lower pressing plate 4 at the bottom of the mounting plate 32 presses down toward the copper clad laminate on the heating plate 5, and the lower pressing plate 4 and the heating plate 5 are heated by turning on the power.
