Description

Technical Field

[0001] This utility model belongs to the field of copper clad laminate cutting technology, and specifically relates to a copper clad laminate cutting device. Background Technology

[0002] Copper clad laminate, also known as substrate, is a plate-shaped material made by impregnating reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing it. It is the basic material for making PCBs.

[0003] Copper-clad laminates need to be cut to the required size during processing. However, the cutting blade needs to press against the copper-clad laminate during the cutting process, which causes the cut edge to warp to one side. The presence of warp makes the copper-clad laminate uneven and affects its use. It is difficult to effectively avoid the occurrence of warp during cutting.

[0004] Therefore, a copper-clad laminate cutting device is proposed. Summary of the Invention

[0005] This invention provides a copper-clad laminate cutting device, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a copper clad laminate (CCL) cutting device, including a base and two CCL conveying frames disposed on its top, with the first CCL conveying frame located on one side of the second CCL conveying frame; baffles symmetrically disposed on the top of the first and second CCL conveying frames; and a cutting moving assembly disposed on the base. The cutting moving assembly includes: a motor disposed on the outer wall of one side of the base; a ball screw fixed to the output end of the motor; a support platform disposed on the ball screw; a support plate disposed on the top of the support platform; a cutting groove formed on one side of the top of the support plate; and a cutting component disposed on the support plate. The cutting component includes: a bracket disposed on the top of the support plate; an electric push rod disposed on the top of the bracket; a cutting machine fixed to the output end of the electric push rod; and a CCL warping and flattening assembly disposed on the support plate and the bracket.

[0007] Furthermore, the copper clad laminate warping and flattening assembly includes: a second electric push rod disposed on the top of the bracket; an upper pressure plate fixed to the output end of the second electric push rod; a pressure roller frame disposed at the bottom of the support plate near the cutting groove side; a lower pressure roller rotating on the inner wall of the pressure roller frame; a pressing platform disposed at the bottom of the support plate near the inner side of the pressure roller frame; and an inclined surface formed at the intersection of the three outer walls of the pressing platform.

[0008] Furthermore, both the copper clad laminate conveyor frame one and the copper clad laminate conveyor frame two are slidably connected to the pallet, and the tops of the copper clad laminate conveyor frame one, the copper clad laminate conveyor frame two and the pallet are all on the same horizontal plane.

[0009] By adopting the above technical solution, the stability of the pallet's horizontal movement between the copper clad laminate conveyor frame one and the copper clad laminate conveyor frame two is ensured through the sliding connection, and the copper clad laminate above it is placed flat by utilizing the fact that the top is on the same horizontal plane, avoiding unevenness.

[0010] Furthermore, the cutting blade on the cutting machine is located directly above the cutting groove;

[0011] By adopting the above technical solution, the cutting machine can pass through the cutting groove to cut the copper-clad laminate.

[0012] Furthermore, the uppermost end of the outer side wall of the lower pressure roller and the top of the support plate are on the same horizontal plane;

[0013] By adopting the above technical solution, the lower pressure roller can contact the bottom of the copper-clad laminate, thereby flattening the downward curling edge at the cut and ensuring a smooth cut.

[0014] Furthermore, the angle of inclination from one end of the inclined surface to the other end gradually decreases.

[0015] By adopting the above technical solution, the downward curling edge at the cut can be gradually flattened, reducing the angle of the curling edge.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes the cooperation of an upper pressure plate, a lower pressure roller, and a pressing table. By using the inclined surface of the pressing table to contact the warped edge at the cut of the copper-clad laminate before the edge is cut, and by changing the angle of the inclined surface, the downward warped edge at the cut can be gradually flattened, reducing the angle of the warped edge. The upper pressure plate and the lower pressure roller also use the upper pressure plate and the lower pressure roller to press the warped edge at the cut of the copper-clad laminate into a horizontal state, ensuring that the cut is flat and avoiding the impact of uneven copper-clad laminate on its use.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model embodiment proposes a copper clad laminate cutting device, including a base 1. The top of the base 1 is provided with a copper clad laminate conveying frame 1 2 and a copper clad laminate conveying frame 2 3. The copper clad laminate conveying frame 1 2 is located on one side of the copper clad laminate conveying frame 2 3 and there is a gap between them. The top of the copper clad laminate conveying frame 1 2 and the copper clad laminate conveying frame 2 3 are symmetrically provided with two baffles 4.

[0027] A motor 51 of the cutting moving assembly 5 is fixedly connected to one side of the outer wall of the base 1 by bolts. A ball screw 52 is fixedly connected to the output end of the motor 51. A support platform 53 is fixedly connected to the screw nut seat on the ball screw 52 by screws. A support plate 54 is provided on the top of the support platform 53 near the gap. Copper clad laminate conveying frame 1 2 and copper clad laminate conveying frame 2 3 are slidably connected to the support plate 54. The tops of copper clad laminate conveying frame 1 2, copper clad laminate conveying frame 2 3 and support plate 54 are all on the same horizontal plane. The sliding connection ensures the stability of the support plate 54 in horizontal movement between copper clad laminate conveying frame 1 2 and copper clad laminate conveying frame 2 3. The fact that the tops are on the same horizontal plane ensures that the copper clad laminate above it is placed flat and avoids unevenness. A cutting groove 55 is provided at the center of one side of the top of the support plate 54.

[0028] The top of the tray 54 is provided with a bracket 61 in the cutting assembly 6 on the other side. The top of the bracket 61 is provided with an electric push rod 62. The electric push rod 62 is fixedly connected to the cutting machine 63 through its output end on one side. The cutting blade on the cutting machine 63 is located directly above the cutting groove 55, which allows the cutting machine 63 to pass through the cutting groove 55 to cut the copper-clad laminate.

[0029] The top of the bracket 61 is located near the electric push rod 62, where the electric push rod 71 of the copper clad laminate warping and flattening assembly 7 is located. The electric push rod 71 is fixedly connected to the upper pressure plate 72 through its output end. The bottom of the support plate 54 is located near one side, where the pressure roller frame 73 is located. The inner side wall of the pressure roller frame 73 is rotatably connected to the lower pressure roller 74. The uppermost end of the outer side wall of the lower pressure roller 74 is on the same horizontal plane as the top of the support plate 54, so that the lower pressure roller 74 can contact the bottom of the copper clad laminate, thereby pressing the downward warping edge of the cut into a horizontal state and ensuring that the cut is flat. The bottom of the support plate 54 is symmetrically located near the bottom of the cutting groove 55, where two pressure tables 75 are symmetrically arranged. The outer side walls of the two pressure tables 75 facing each other are provided with inclined surfaces 76. The inclination angle from one end of the inclined surface 76 to the other end gradually decreases, which can gradually flatten the downward warping edge of the cut and reduce the inclination angle of the warping edge.

[0030] The specific implementation method is as follows: When cutting the copper-clad laminate, under the limitation of the baffle 4, the copper-clad laminate is pushed and moved on the copper-clad laminate conveyor frame 1 2 and the copper-clad laminate conveyor frame 2 3, so that the cutting point is located directly below the cutting machine 63, and the copper-clad laminate is clamped and fixed by external clamps.

[0031] At this time, the height of the upper pressure plate 72 is adjusted according to the height of the copper-clad laminate. Specifically, the electric push rod 71 is controlled to drive the upper pressure plate 72 to move downward through its output end on one side, so that the bottom of the upper pressure plate 72 is in contact with the top of the copper-clad laminate, thereby limiting the copper-clad laminate in the vertical direction. The electric push rod 62 is controlled to drive the cutting machine 63 to move downward through its output end on one side. After the cutting machine 63 contacts the copper-clad laminate, it cuts it. The cut part of the copper-clad laminate produces a downward curling edge under the pressure. Then, the motor 51 is controlled to drive the ball screw 52 to rotate through its output end on one side. The support platform 53 on the ball screw 52 moves linearly on the base 1. The support plate 54 and the cutting machine 63 move horizontally and linearly at the same time. The cutting machine 63 cuts the copper-clad laminate linearly until it is cut off.

[0032] As the pallet 54 moves, the upper pressure plate 72, the lower pressure roller 74, and the pressure table 75 move horizontally and linearly in sync. The inclined surface 76 on the pressure table 75 contacts the warped edge at the cut of the copper-clad laminate first. Under the pressure of the pressure table 75, the downward warped edge at the cut can be gradually flattened by the change in the inclination angle of the inclined surface 76, reducing the inclination angle of the warped edge. The upper pressure plate 72 and the lower pressure roller 74 make the warped edge at the cut of the copper-clad laminate flattened, ensuring that the cut is flat and avoiding unevenness of the copper-clad laminate from affecting its use.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
