Description

Technical Field

[0001] The invention relates to the technical field of edge trimming machines, and in particular to an edge trimming machine for an aluminum-based copper-clad laminate. Background Art

[0002] Aluminum-based copper-clad laminate is an aluminum-based plate. It is a plate-like material made of electronic glass fiber cloth or other reinforcing materials impregnated with resin, single resin, etc. as an insulating adhesive layer, covered with copper foil on one or both sides and hot-pressed. Generally, a single-sided board consists of a circuit layer (copper foil), an insulating layer, and a metal base layer. The double-sided board used for high-end has a structure of circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few multi-layer boards can be made by laminating ordinary multi-layer boards with insulating layers and aluminum bases.

[0003] During the processing of aluminum-based copper-clad laminates, the material plates need to be trimmed, and then the burrs on the material plates are cleaned or the material plates are cut into required sizes. However, during the processing of existing aluminum-based copper-clad laminates, two sets of trimming equipment are often required to be used in conjunction. First, one set of opposite edges of the material plate is trimmed, and then the material plate is transported to the next set of cutting equipment to complete the trimming of the other set of opposite edges of the material plate. The conversion between the two sets of cutting equipment increases the conveying distance of the material plates, which is time-consuming and inefficient. It also increases the floor space occupied by the equipment and has a high cost of use. Summary of the invention

The height of the pressing plate is lower than that of the cutting knife. A spring is fixedly installed between the pressing plate and the tool rest, and the spring is sleeved outside the vertical rod.

[0014] Preferably, the elastic resetting member includes an outer cylinder, an inner cylinder and a tension spring. The outer cylinder is fixedly installed on the side wall of the base. The inner cylinder is slidably assembled inside the outer cylinder, and one end of the inner cylinder far away from the base is fixedly installed on the installation frame.

Detailed implementation mode

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0031] As Figures 1 to 8 shown, the edge trimming machine for aluminum-based copper clad laminate of the present invention includes a frame 10, a cutting unit 20, an adsorption table 30, a flipping assembly 40, an elastic resetting member 50, a pushing mechanism 60 and an adjusting mechanism 70. The frame 10 is used for conveying the stock plate. The cutting unit 20 has two symmetrically distributed in the middle parts on both sides of the frame 10 and is used for trimming the opposite sides of the stock plate. The flipping assembly 40, the elastic resetting member 50 and the pushing mechanism 60 are all arranged between the two cutting units 20. The adsorption table 30 can drive the stock plate to rotate under the action of the flipping assembly 40 to change the orientation of the stock plate. The cutting unit 20 can move away from the frame 10 under the combined action of the flipping assembly 40 and the pushing mechanism 60, and can also approach the frame 10 under the action of the elastic resetting member 50.

[0032] Refer to Figure 1 and Figure 3 , a cavity 11 is opened in the middle of the frame 10. Two groups of conveyor belts 12 are symmetrically arranged inside the cavity 11, and the top surface of the conveyor belt 12 is higher than the top surface of the frame 10 for conveying the stock plate to move. Notches 13 are opened in the middle of the opposite sides of the frame 10.

[0033] Refer to Figure 1 , Figure 2 and Figure 4, the cutting unit 20 includes a mounting frame 21, a support table 22 and a cutting knife 23. The mounting frame 21 is arranged inside the notch 13 and can move relative to the machine frame 10 closer to or away from the machine frame 10. The support table 22 is arranged on the side of the mounting frame 21 close to the machine frame 10, and the top surface of the support table 22 is flush with the top surface of the conveyor belt 12, so that the edge of the stock plate can extend above the support table 22. The cutting knife 23 is arranged directly above the support table 22 and can move up and down relative to the support table 22 to cut the edge of the stock plate.

[0034] Inside the mounting frame 21, there is a tool rest 211 located above the support table 22. The cutting knife 23 is arranged on the tool rest 211. Inside the mounting frame 21, there is a hydraulic cylinder 212 for driving the tool rest 211 to move up and down, so that the tool rest 211 can drive the cutting knife 23 to move up and down for cutting the edge of the stock plate. Inside the tool rest 211, a vertical rod 213 is slidably assembled along its height direction. The bottom end of the vertical rod 213 is fixedly installed with a pressing plate 214, and the pressing plate 214 is located on the side of the cutting knife 23 close to the machine frame 10. The height of the pressing plate 214 is lower than that of the cutting knife 23. A spring 215 is fixedly installed between the pressing plate 214 and the tool rest 211, and the spring 215 is sleeved outside the vertical rod 213. When the tool rest 211 descends, the spring 215 can drive the pressing plate 214 to descend, contacting the stock plate one step ahead of the cutting knife 23 and pressing the stock plate tightly before cutting to improve the cutting effect.

[0035] An inclined part 216 is also arranged inside the mounting frame 21. The inclined part 216 is located on the side of the support table 22 far from the machine frame 10, and a collection box 217 is arranged at the bottom of the inclined part 216, so that the waste of the stock plate cut off can slide down along the inclined part 216 and be collected by the collection box 217. For the convenience of moving the mounting frame 21, rollers are also arranged at the bottom of the mounting frame 21.

[0036] Reference Figure 2 And Figure 3 The adsorption table 30 is arranged in the middle of the cavity 11 between the two mounting frames 21, and the top surface of the adsorption table 30 is flush with the top surface of the conveyor belt 12. Inside the adsorption table 30, there are vacuum suction cups 31. At the bottom of the adsorption table 30, there is an installation cylinder 32. Inside the installation cylinder 32, there is a vacuum pump connected to the vacuum suction cups 31, which can pump vacuum into the vacuum suction cups 31 and then grab and adsorb the stock plate.

[0037] Reference Figure 2, the flipping assembly 40 includes a base 41, a rotating table 42, and a motor 43. The base 41 is disposed below the frame 10. The rotating table 42 is rotatably assembled on the base 41, and the mounting cylinder 32 is coaxially disposed above the rotating table 42. The motor 43 is fixedly installed on the top of the base 41. A gear set located inside the base 41 is provided between the output end of the motor 43 and the rotating table 42, so that the motor 43 can drive the rotating table 42 to rotate through the gear set, and then the mounting cylinder 32 drives the adsorption table 30 and the adsorbed sheet material to rotate, so that the uncut two sides of the sheet material are rotated into the two cutting units 20 for edge trimming.

[0038] Reference Figure 2 , the elastic reset member 50 includes an outer cylinder 51, an inner cylinder 52, and a tension spring 53. The outer cylinder 51 is fixedly installed on the side wall of the base 41. The inner cylinder 52 is slidably assembled in the outer cylinder 51, and one end of the inner cylinder 52 away from the base 41 is fixedly installed on the mounting frame 21. The two ends of the tension spring 53 are respectively fixedly connected to the outer cylinder 51 and the inner cylinder 52, and the tension spring 53 is in a stretched state, and thus always applies a pulling force in the direction of the outer cylinder 51 to the inner cylinder 52. The tension spring 53 expands and contracts by the sliding of the inner cylinder 52 in the outer cylinder 51, so that the mounting frame 21 can move away from or close to the frame 10, so as to adjust the distance between the two mounting frames 21 and adjust the cutting length of the sheet material.

[0039] Reference Figure 2 And Figure 5 , the pushing mechanism 60 includes a support cylinder 61, a short push rod 62, a long push rod 63, and a convex platform 64. The support cylinder 61 is fixedly installed between the rotating table 42 and the mounting cylinder 32, and the support cylinder 61 is coaxially disposed with the rotating table 42. There are two short push rods 62 and two long push rods 63, and they are slidably assembled inside the support cylinder 61 along the radial direction of the support cylinder 61. The two short push rods 62 and the two long push rods 63 are symmetrically distributed in the support cylinder 61, and the short push rod 62 and the long push rod 63 are perpendicularly arranged. There are two convex platforms 64 respectively fixedly installed on the opposite sides of the two mounting frames 21. The short push rod 62 and the long push rod 63 can both abut against the convex platform 64 during rotation and push the convex platform 64 to make the two mounting frames 21 move away from each other;

[0040] In this solution, two short push rods 62 are respectively abutted against two bosses 64 at the initial position, supporting the two mounting brackets 21 at an appropriate cutting distance, so that the cutting knife 23 can cut the two long sides of the material plate. When the rotating table 42 rotates to make the suction table 30 rotate to adjust the direction of the material plate, the support cylinder 61 can rotate synchronously, so that the short push rod 62 gradually moves away from the boss 64 during rotation, while the long push rod 63 abuts against the boss 64 during rotation, pushing the boss 64 to make the two mounting brackets 21 move away from each other, supporting the two mounting brackets 21 to a farther position, so that the distance between the cutting knives 23 increases, and then the cutting knife 23 can cut the short side of the material plate. By making the short push rod 62 and the long push rod 63 slide in the support cylinder 61 and adjusting their extended lengths, the support distance between the two mounting brackets 21 can be adjusted, and then the distance between the two cutting knives 23 can be changed, and the cutting length can be adjusted to facilitate cutting of material plates of different sizes.

[0041] Reference Figures 5 to 8 , the adjusting mechanism 70 includes a column 71, a ring body 72, an upper frame body 73, a lower frame body 74 and a connecting shaft 75. The column 71 is coaxially fixed in the middle of the support cylinder 61. There are two ring bodies 72 respectively rotatably assembled at the upper and lower ends of the column 71. The upper frame body 73 and the lower frame body 74 are arc-shaped and there are two of each. The two upper frame bodies 73 are both arranged on the side wall of the upper ring body 72, and the two lower frame bodies 74 are both arranged on the side wall of the lower ring body 72. There are multiple connecting shafts 75 respectively arranged in the upper frame body 73 and the lower frame body 74. The end parts of the connecting shafts 75 in the two upper frame bodies 73 are respectively fixedly installed on the two short push rods 62, and the end parts of the connecting shafts 75 in the two lower frame bodies 74 are respectively fixedly installed on the two long push rods 63;

[0042] By rotating the ring body 72 outside the column 71, when driving the upper frame body 73 to rotate, it can push the connecting shaft 75 to drive the short push rod 62 to slide, adjust the extended length of the two short push rods 62 in the support cylinder 61, and adjust the cutting position of the cutting knife 23 on the long side of the material plate. When driving the lower frame body 74 to rotate, it can push the connecting shaft 75 to drive the long push rod 63 to slide, adjust the extended length of the two long push rods 63 in the support cylinder 61, and adjust the cutting position of the cutting knife 23 on the width side of the material plate.

[0043] On the side wall of the support cylinder 61, there are two symmetrically arranged arc-shaped grooves 611, one above the other. Inside both of the two arc-shaped grooves 611, there is a connecting rod 612 slidably assembled. One end of each of the two connecting rods 612 extends into the support cylinder 61 and is fixedly connected to the upper frame body 73 and the lower frame body 74 respectively. The other ends of the two connecting rods 612 are both fixedly installed with locking plates 613 located outside the support cylinder 61. Inside the locking plate 613, there is a locking bolt 614 threadedly connected. Along the circumferential direction of the side wall of the support cylinder 61, there are a plurality of bolt holes 615 adapted to the locking bolt 614, and the tail end of the locking bolt 614 is threadedly connected into one of the bolt holes 615. By pushing the locking plate 613 to drive the connecting rod 612 to slide in the arc-shaped groove 611, the upper frame body 73 or the lower frame body 74 can be driven to rotate the ring body 72, and then the protruding length of the short push rod 62 or the long push rod 63 in the support cylinder 61 can be adjusted to adjust the support distance between the two mounting brackets 21. Then, rotate the locking bolt 614 so that its tail end is screwed into the corresponding bolt hole 615, and the position of the upper frame body 73 or the lower frame body 74 can be locked, making it unable to rotate further, and then locking the protruding length of the short push rod 62 or the long push rod 63, so as to facilitate the equipment to cut workpieces of different sizes.

[0044] Working principle: According to the size of the required workpiece, adjust the short push rod 62 and the long push rod 63 to appropriate protruding lengths. The short push rod 62 supports the two mounting brackets 21 to an appropriate distance, and then the conveyor belt 12 conveys the workpiece between the two mounting brackets 21, so that the two long sides of the workpiece respectively enter the support platforms 22 inside the two mounting brackets 21. The vacuum pump and the vacuum suction cups 31 are used to adsorb the workpiece. Then, the hydraulic cylinder 212 pushes the tool holder 211 down. After the workpiece is pressed by the pressing plate 214, the cutting knife 23 cuts the long side of the workpiece, and the collection box 217 recycles the cut waste.

[0045] The tool holder 211 is lifted and reset. The motor 43 drives the rotating table 42 to rotate 90°, driving the adsorption table 30 and the workpiece to rotate synchronously. At the same time, the support cylinder 61 rotates with the rotating table 42, so that the short push rod 62 gradually moves away from the convex platform 64 during rotation, while the long push rod 63 contacts the convex platform 64 during rotation, pushing the convex platform 64 to make the two mounting brackets 21 move away from each other, increasing the distance between the two mounting brackets 21, so that the short side of the workpiece moves to the support platform 22 during rotation, and then the cutting knife 23 cuts it, completing the trimming of the four sides of the workpiece.

[0046] After the cutting is completed, the rotating table 42 rotates back to the original position. The long push rod 63 moves away from the convex platform 64. The two mounting brackets 21 approach each other under the action of the tension spring 53. Again, the short push rod 62 supports the convex platform 64. The vacuum pump is adjusted to release the adsorption of the vacuum suction cups 31 on the workpiece, so that the conveyor belt 12 outputs and unloads the cut workpiece, and conveys a new workpiece between the two mounting brackets 21 for a new round of trimming treatment.

[0047] In the present invention, through the mutual cooperation of the short push rod 62, the long push rod 63 and the boss 64, the distance between the two mounting brackets 21 is preferably adjusted, and the distance between the two cutting knives 23 can be quickly determined, ensuring that the length of the material plate reaches the required length after trimming. And after one set of opposite sides of the material plate is trimmed, by rotating the material plate and the short push rod 62 and the long push rod 63, the distance between the two cutting knives 23 can be quickly adjusted, so that the cutting knives 23 accurately move to the corresponding positions required for trimming the other set of opposite sides of the material plate, and the untrimmed opposite sides of the material plate are synchronously fed under the cutting knives 23, and then the trimming is quickly completed, trimming the material plate to the required size. Without the need for multiple sets of trimming equipment to cooperate, the trimming of the four sides of the material plate can be efficiently and accurately completed, reducing the trimming cost. At the same time, it can also reduce the floor area of the equipment, shorten the conveying process of the material plate, and reduce the risk of the material plate being scratched and damaged during conveying;

[0048] By adjusting the lengths of the short push rod 62 and the long push rod 63 extending in the support cylinder 61, the support distance between the short push rod 62 and the long push rod 63 for the two mounting brackets 21 can be adjusted, and then the trimming distance between the two cutting knives 23 can be adjusted, so as to facilitate the trimming process of material plates of different sizes, improve the versatility of the equipment, and increase the applicable range of the equipment.

[0049] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
