DETAILED DESCRIPTION

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment: A copper substrate processing cutting machine, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a frame 1, a cutting knife 2, a guide plate 21, a knife mounting plate 3, a first cylinder 4 and a conveying assembly. The frame 1 is a "n"-shaped structure. The front of the frame 1 is open. The cutting knives 2 are installed on the inner walls on the left and right sides of the frame 1. The blades of the cutting knives 2 are in contact with each other. The right cutting knife 2 is fixed to the right inner wall of the frame 1. The left cutting knife 2 passes through the frame 1 and its back is connected to the knife mounting plate 3 slidably arranged in the inner cavity of the frame 1. The knife mounting plate 3 is connected to the piston rod of the first cylinder 4 arranged on the frame 1. The end of the tool mounting plate 3 is connected, and the other end of the tool mounting plate 3 is slidably connected to the inner cavity of the frame 1. Guide plates 21 are installed on the inner walls on the left and right sides of the front of the frame 1. The guide plates 21 are in contact with the cutting knife 2 and are flush with it. The setting of the guide plates 21 facilitates the copper substrate to slide between the two cutting knives 2. The frame 1 is provided with a conveying component for conveying the copper substrate to between the two cutting knives 2 for cutting operation. The conveying component moves horizontally to convey the copper substrate to between the two cutting knives 2. The first cylinder 4 drives the cutting knife 2 to reciprocate to cut the copper substrate equidistantly.

[0030] like Figure 4 and Figure 5 As shown, the conveying assembly includes a moving frame 5, a support plate 51, a placement frame 52 and a second cylinder 53. The second cylinder 53 is arranged in the inner cavity on both sides of the frame 1, and the moving frame 5 is slidably arranged on the top and bottom of the outer walls on the left and right sides of the frame 1. The end of the piston rod of the second cylinder 53 passes through the frame 1 and is connected with the longitudinal part of the moving frame 5. The second cylinder 53 is arranged in the inner cavity of the frame. The upper and lower parts of the moving frame 5 are respectively provided with a placement frame 52 for placing the copper substrate and a support plate 51 for supporting the copper substrate to be cut by the cutting knife 2. The support plate 51 and the placement frame 52 are correspondingly arranged directly above and directly below the cutting knife 2. The rod-shaped member of the contact part of the placement frame 52 with the copper substrate is rotatably arranged on the placement frame 52, and the rotational arrangement is helpful to protect the copper substrate.

[0031] like Figure 6 and Figure 7 As shown, it also includes a connecting seat 6, an L-shaped vertical rod 7, a cross bar 8, a first elastic member 9, a roller 10, a lifting plate 11, a first limiting guide rod 1101 and a lifting guide block 12. An arc-shaped connecting seat 6 is installed at the upper corner of the front part of the frame 1. The L-shaped vertical rod 7 is slidably installed on the connecting seat 6 through a rod-shaped connecting member. The first elastic member 9 is wound around the rod-shaped connecting member. The first elastic member 9 is a compression spring. The cross bars 8 are symmetrically slidably installed on the opposite sides of the two L-shaped vertical rods 7. The ends of the cross bars 8 are spherical structures. The cross bars 8 are arranged on the upper part of the L-shaped vertical rods 7. The connection between the cross bars 8 and the L-shaped vertical rods 7 is provided with a resistance The damping setting can realize that the cross bar 8 is kept at a certain height position of the L-shaped vertical pole 7. The roller 10 is installed at the lower end of the L-shaped vertical pole 7. The lifting plate 11 is movably installed on the support plate 51 through the first limiting guide rod 1101. Lifting guide blocks 12 are installed on both sides of the bottom of the lifting plate 11 with the support plate 51 as the center. The distance between the bottom end of the lifting guide block 12 and the lifting plate 11 is the width value of the copper substrate frame. When the roller 10 rolls along the lifting guide block 12, the lifting plate 11 performs a lifting movement. The copper substrate lifting function is realized by the rising movement of the lifting plate 11, which provides convenience for the cutting of the cutting knife 2.

[0032] like Figure 8 As shown, it also includes a second limiting guide rod 13, a limiting rod 14 and an adjusting screw 141. The second limiting guide rod 13 and an adjusting screw 141 parallel to the placing frame 52 are arranged on the transverse connecting plate between the placing frame 52 and the movable frame 5. The adjusting screw 141 is threadedly connected with a limiting rod 14 that extends into the placing frame 52 to limit the copper substrate. The limiting rod 14 can be used to limit the copper substrates of different specifications of the placing frame 52. The limiting rod 14 is slidably connected to the second limiting guide rod 13.

[0033] like Fig. 9 As shown, it also includes a 7-shaped connecting rod 15, a connecting plate 16, a pulley 17 and a second elastic member 18. The inner walls on the left and right sides of the front of the frame 1 are all equipped with a 7-shaped connecting rod 15. The 7-shaped connecting rod 15 is arranged below the cutting knife 2, but above the supporting plate 51. The end of the 7-shaped connecting rod 15 is rotatably installed with a connecting plate 16, and the connecting plate 16 can only rotate in one direction from front to back. The connection between the connecting plate 16 and the 7-shaped connecting rod 15 is wound with a second elastic member 18. The two ends of the second elastic member 18 are respectively connected to the connecting rod 15 and the connecting plate 16. The second elastic member 18 is preferably a torsion spring. The opposite ends of the two connecting plates 16 are connected with pulleys 17. The setting of the pulley 17 facilitates the copper substrate to pass through between the pulleys on both sides, thereby reducing the movement resistance of the copper substrate. Through the cooperation of the connecting rod 15, the connecting plate 16 and the second elastic member 18, it can be avoided that the copper substrate that has been cut is driven to the front of the frame 1 when the movable frame 5 moves forward.

[0034] like Figure 1 As shown, it also includes a collecting frame 19, which is installed at the lower part of the frame 1 and is arranged below the cutting knife 2. The collecting frame 19 can collect the cut copper substrate in real time.

[0035] like Fig.10 As shown, a cleaning member 20 is also included. The rear part of the placement frame 52 is provided with a cleaning member 20 for cleaning debris on the cutting blade 2. The cleaning member 20 cleans the upper part of the cutting blade to keep the cutting blade 2 clean.

[0036] When the plate cutting machine is used to cut the copper substrate, the piston rod of the second cylinder 53 is extended forward, thereby driving the moving frame 5, the support plate 51 and the placement frame 52 to move synchronously toward the front of the frame 1. At this time, the copper substrate to be cut is placed in the placement frame 52, and the limit rod 14 is adjusted by rotating the adjustment screw 141, thereby effectively limiting the copper substrate in the placement frame 52 to prevent it from tilting; at the same time, according to the height of the copper substrate in the placement frame 52, the cross bar 8 is slid upward or downward to make the cross bars 8 on both sides flush with the top frame of the copper substrate placed in the placement frame 52; then, the piston rod of the second cylinder 53 is retracted, and the moving frame 5, the support plate 51 and the placement frame 52 move synchronously toward the rear of the frame 1. When the copper substrate moves to the two cross bars 8, the copper substrate exerts an extrusion effect on the cross bars 8 on both sides. After being extruded by the copper substrate, the cross bars 8 drive the L-shaped vertical rods 7 on both sides to move in opposite directions, so that the roller 10 and the lifting guide block 12 are in the same straight line. On the line, with the contraction movement of the piston rod of the second cylinder 53, the roller 10 rolls along the outer wall of the lifting guide block 12. Since the roller 10 is fixed, the lifting guide block 12 drives the lifting plate 11 to lift upward under the extrusion of the roller 10, thereby lifting the copper substrate upward, and the lifting distance is consistent with the distance of the frame that needs to be cut off at the bottom of the copper substrate. Then, the first cylinder 4 drives the tool mounting plate 3 connected to its piston rod and the cutting knife 2 installed on the tool mounting plate 3 to move horizontally, thereby completing the cutting of the copper substrate frame part; after the copper substrate frame part is cut, when the copper substrate is driven to reciprocate back and forth by the telescopic movement of the second cylinder 53, the upper part of the copper substrate will no longer squeeze the cross bar 8, and the roller 10 will no longer move along the lifting guide block 12. The distance between the lifting plate 11 and the cutting knife 2 is the distance that the copper substrate needs to cut, and the cutting knife 2 is driven by the telescopic movement of the first cylinder 4 to cut the copper substrate equidistantly, thereby realizing efficient and equidistant cutting operation of the copper substrate.

[0037] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
