Description

Technical Field

[0001] The utility model relates to the technical field of PCB production, in particular to a PCB plate cutting machine. Background Art

[0002] PCBs use copper plates as raw materials due to their excellent electrical and thermal conductivity. As an excellent conductive material, copper's electrical conductivity is second only to silver, ranking second among all metals. Copper is also easy to process and can be formed into the required circuit patterns through processes such as etching and drilling. This easy processability enables copper plates to meet the design and manufacturing needs of various complex circuit boards.

[0003] The basic function of the cutting machine is to cut the original copper plate into a size suitable for further processing on the production line. This step is crucial to improving material utilization and reducing costs. By precisely controlling the cutting size, the raw materials can be maximized and waste can be reduced. At the same time, the correct cutting size also helps the subsequent typesetting and manufacturing processes, improving overall production efficiency.

[0004] When cutting a copper plate, when the cutting blade descends to cut the copper plate, in the absence of a positioning function for the copper plate, the cut portion of the copper plate is prone to bending. Therefore, a PCB plate cutting machine is proposed, which can position the cut portion of the copper plate. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] A PCB sheet material cutting machine includes a support 1, a bracket 2 is installed on the outer end of the support 1, a cutting knife 21 is installed on the inner side of the bracket 2, two hydraulic rods 22 fixed to the bracket 2 are installed on the upper side of the cutting knife 21, and a mounting plate 23 is fixed to the output end of the two hydraulic rods 22, which is connected to the cutting knife 21. The mounting plate 23 and the cutting knife 21 are connected in a detachable manner. The cutting knife 21 is driven to rise and fall by the lifting of the hydraulic rod 22, so that the copper plate raw material can be cut by the cutting knife 21.

[0027] In this embodiment, Figure 1-5 , several first support rollers 3 and several second support rollers 31 are installed on the inner side of the support 1, and the copper plate can be transported by the rotation of the first support rollers 3 and the second support rollers 31. At the same time, two third support rollers 7 are installed between the adjacent first support rollers 3 and the second support rollers 31. The third support rollers 7 are rotatably connected to the support 1 through support shafts, and the third support rollers 7 are located on both sides of the lower end of the cutting knife 21, so that the third support rollers 7 can support the two sides of the copper plate that needs to be cut. A pressing plate 4 is installed on the lower side of the cutting knife 21, and the copper plate can be pressed by the pressing plate 4 to keep the copper plate stable during cutting and reduce bending at the cutting part of the copper plate.

[0028] Among them, the first support roller 3 and the second support roller 31 are both rotatably connected to the support 1 through a support shaft, and a pulley is installed on one side of the support shaft located inside the support 1, and belts are installed on the outer sides of the pulleys corresponding to the first support roller 3 and the second support roller 31, and the rotation of the first support roller 3 and the second support roller 31 is transmitted by the belt. A driving motor 11 is installed on one side of the outer end of the support 1, and the output shaft of the driving motor 11 is connected to the support shaft of a first support roller 3. The specific connection method can adopt the existing technology. When the driving motor 11 is started to drive a first support roller 3 to rotate, the transmission action of the belt can make all the first support rollers 3 and the second support rollers 31 rotate, so as to facilitate the transportation of the copper plate raw material.

[0029] Specifically, a cavity 41 is provided in the middle of the pressing plate 4, which facilitates the cutting knife 21 to pass through the pressing plate 4 to cut the copper plate. A rubber pad 42 is pasted on the lower end surface of the pressing plate 4, so that the pressing plate 4 contacts the surface of the copper plate through the rubber pad 42, thereby improving the anti-slip effect. At the same time, a double-output shaft motor 8 is installed at the bottom of the inner end of the bracket 2, and the outer ends of the double-output shaft motor 8 are respectively connected to the driving rod 81 on both sides. The specific connection method can adopt the existing technology, and the inner sides of the two ends of the bracket 2 are respectively rotatably connected with the adjusting rod 82, and the driving rod 81 is meshed with the adjusting rod 82 at one end away from the double-output shaft motor 8. The meshing connection between the driving rod 81 and the adjusting rod 82 facilitates the rotation of the driving rod 81 to be transmitted to the adjusting rod 82, driving the adjusting rod 82 to rotate, and the adjusting rod 82 is threadedly connected to the pressing plate 4, and when the two adjusting rods 82 rotate at the same time, the pressing plate 4 can be driven to rise and fall.

[0030] In a further embodiment, Figure 2 、 Figure 4 and Figure 5 Two first slides 5 are slidably connected inside the pressing plate 4. The first slides 5 are located on both sides of the inner end of the cavity 41. A brush 51 is installed on the lower surface of one end of the first slide 5 located inside the cavity 41. After the brush 51 is driven by the first slide 5 to move horizontally, the brush 51 cleans the debris left on the copper plate after cutting.

[0031] Furthermore, two mounting brackets 6 are installed on the upper side of the pressure plate 4, and the mounting brackets 6 are fixed to the bracket 2. Electric push rods 61 are fixed on the opposite sides of the two mounting brackets 6, and a connecting plate 62 is fixed to the output end of the electric push rod 61. A limiting plate 52 is fixed to the upper end of the first slide 5, and the connecting plate 62 is slidably connected to the inside of the limiting plate 52, so that when the pressure plate 4 is raised or lowered, the limiting plate 52 can be raised or lowered on the outside of the connecting plate 62, so that the raising and lowering of the pressure plate 4 and the translation of the first slide 5 do not interfere with each other, and through the extension and retraction of the electric push rod 61, the connecting plate 62 can be used to drive the limiting plate 52 to translate, thereby causing the first slide 5 to translate.

[0032] Working principle: Place the copper plate that needs to be cut on the first support roller 3, and transport the copper plate through the first support roller 3 and the second support roller 31. When the copper plate needs to be cut, start the double-axis motor 8 to drive the two drive rods 81 to rotate, and then make the two adjustment rods 82 rotate at the same time. At this time, the pressing plate 4 drops as a whole to press the copper plate down. The pressing plate 4 contacts the surface of the copper plate through the rubber pad 42. At the same time, the third support roller 7 supports the copper plate. At this time, the two sides of the copper plate to be cut are positioned by the pressing plate 4 and the third support roller 7 to reduce the bending of the copper plate during cutting.

[0033] After the copper plate is cut, debris is likely to remain near the cutting area. At this time, the electric push rod 61 is started to push the connecting plate 62 to move horizontally, thereby causing the limit plate 52 and the first slide 5 to move horizontally. At this time, the brush 51 cleans the debris remaining at the cutting area of the copper plate.
