Description

Technical Field

[0001] The present invention relates to the technical field of machine tool cutting, in particular to a metal waste recycling and processing device. Background Art

[0002] Flexible printed circuits (FPCs) are printed circuit boards (PCBs) made from flexible substrates. They are bendable, foldable, and lightweight, making them widely used in modern electronic devices. When FPCs contain high-value areas, such as precious metal coatings or high-purity copper functional areas, recycling requires cutting these high-value areas to selectively enrich the precious metals and maximize the economic value of the scrapped FPCs.

[0003] A Chinese invention patent application, publication number CN119017461A, discloses a cutting machine for processing flexible circuit boards. The machine comprises a placement table and a lifting box. The flexible circuit board is placed on the placement table, and the lifting box is moved upward, driving a fixed tooth plate inside the lifting box to move. The fixed tooth plate engages with a rotating gear, causing the rotating gear to rotate on a rotating rod. The rotation of the rotating gear drives the movable tooth plate to slide within a sliding compartment, causing the pressing plate at the bottom of the movable tooth plate to fit the placement table, firmly fixing the flexible circuit board on the placement table. When the flexible circuit board on the placement table needs to be placed or removed, the driving assembly can be used to raise the cutting assembly to the top, making it easier for staff to place and remove the circuit board. When the above patent is used to cut flexible circuit boards to recover high-value components, after the high-value components are cut, they remain on the placement table, at the same level as the flexible circuit board. Since the placement table is fixed, the high-value components are not easy to remove from the placement table. Summary of the Invention

[0004] The present invention provides a metal waste recycling and processing device to solve the technical problem in the prior art that the cut high-value components and the workpiece to be cut are on the same horizontal plane, making it difficult to remove the high-value components.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A metal scrap recycling and processing equipment includes a frame and a cutting head. The frame is used to place a piece to be cut. The cutting head is slidably assembled on the frame so that the cutting head corresponds to a predetermined cutting position of the piece to be cut and passes vertically through the piece to be cut. It also includes a support plate. There are multiple support plates, and the multiple support plates are parallel to each other. The opposite surfaces of two adjacent support plates are perpendicular to the piece to be cut. The support plates are slidably assembled on the frame along a direction parallel to the piece to be cut so that a gap is generated between the support plates for avoiding the cutting head; when the cutting head cuts the piece to be cut, the support plate fits the piece to be cut to generate a supporting force opposite to the pressure of the cutting head on the piece to be cut; the support plate is slidably assembled on the frame along a direction perpendicular to the piece to be cut so that the support plate approaches or moves away from the piece to be cut, and the support plate is rotatably assembled on the frame, and the axis around which the support plate rotates is parallel to the piece to be cut.

[0007] The support plate provides support for the bottom surface of the workpiece to be cut, overcomes the collapse of the workpiece to be cut caused by the pressure of the cutting head on the workpiece to be cut, prevents the cutting path from being offset, and is less likely to produce burrs, brushing or delamination on the cutting edge; the support plate slides to adjust the position and size of the gap to avoid mechanical collision between the support plate and the tool, and protects the tool; after the high-value component is cut, the workpiece to be cut is fixed, and the support plate moves down, so that the support plate is away from the workpiece to be cut, and the cut high-value component moves down synchronously with the support plate to the bottom of the workpiece to be cut, so that the workpiece to be cut and the high-value component are separated in the vertical direction; then the support plate rotates so that the top surface of the support plate is an inclined surface, and the high-value component slides along the inclined surface, making it easy to remove the high-value component from the support plate; the support plate can be used to support the workpiece to be cut, and can also be used as a guide plate to guide the cut high-value component out, with diverse functions and high equipment integration.

[0008] Furthermore, a pressure plate is provided on the frame, and the pressure plate and the support plate are located on both sides of the workpiece to be cut. The pressure plate is slidably assembled on the frame in a direction perpendicular to the workpiece to be cut. A through hole is provided on the pressure plate for avoiding the cutting head. When the cutting head cuts the workpiece to be cut, the pressure plate fits against the workpiece to be cut to generate pressure in the same direction as the cutting direction of the cutting head.

[0009] The pressure plate generates pressure perpendicular to the top surface of the workpiece to be cut, reducing vibration during the cutting process, preventing the flexible workpiece from shifting or warping during the cutting process, evenly distributing the cutting pressure, reducing material deformation or fracture caused by local stress, and ensuring the integrity of the high-value components cut.

[0010] Furthermore, the support plate is slidably assembled on the mounting frame 1 in a direction perpendicular to the workpiece to be cut, and at least two linear actuators 8 are assembled on the frame. The driving direction of the linear actuator 8 is perpendicular to the workpiece to be cut, and the mounting frame 1 is provided with a rotating shaft 1 and a rotating shaft 2 which are parallel to each other. The rotating shaft 1 and the rotating shaft 2 are both parallel to the end surface of the support plate that is in contact with the workpiece to be cut. The rotating shaft 1 rotates around its own axis and is assembled at the output end of one of the linear actuators 8. The rotating shaft 2 rotates around its own axis and is assembled at the output end of the linear actuator 8. The rotating shaft 2 slides and is assembled at the output end of the linear actuator 8 in a direction that is parallel to the end surface of the support plate and perpendicular to the axis of the second rotating shaft, so that the mounting frame 1 rotates around the axis of the rotating shaft 1.

[0011] The linear actuator 8 can drive the support plate to move closer to or away from the workpiece to be cut, and can also drive the support plate to rotate. It has diverse functions and a high degree of device integration.

[0012] Furthermore, a push plate four is assembled on the pressure plate in a sliding manner perpendicular to the workpiece to be cut, and the push plate four is used to push the cut high-value components toward the direction where the support plate is located.

[0013] Furthermore, a pressure sensor is mounted on the push plate 4, and the pressure sensor is used to detect the pressure of the push plate 4 on the high-value component.

[0014] The push plate can push the high-value component away from the workpiece to be cut. The pressure sensor detects whether the high-value component is separated from the workpiece to be cut, ensuring the normal use of the tool and ensuring that the high-value component is separated from the workpiece to be cut.

[0015] Furthermore, a driving mechanism 1 is installed on the mounting frame 1, and the driving mechanism 1 includes a push plate 2 and a push plate 3. The push plate 2 and the push plate 3 are slidably installed on the mounting frame 1 in a direction perpendicular to the opposite surfaces of two adjacent support plates. The push plate 2 and the push plate 3 are used to drive the support plates to slide to change the position and width of the gap between the support plates.

[0016] The pushing mechanism can be set up in two or more groups so that the support plates on both sides of the gap avoiding the cutting head fit together, increasing the overall rigidity and stability of the support structure, reducing the displacement of the support plates caused by vibration or external force during the cutting process, and improving the cutting accuracy.

[0017] Furthermore, a movable frame is assembled by sliding on the frame in a direction perpendicular to the opposite surfaces of two adjacent support plates. A placement slot 1 is provided on the frame, and a placement slot 2 is provided on the movable frame. Both ends of the piece to be cut are placed between the placement slot 1 and the placement slot 2.

[0018] Furthermore, the frame and the movable frame are both equipped with a clamping plate that is slidably assembled in a direction perpendicular to the workpiece to be cut, and the rotating plate is rotatably assembled on the clamping plate. The axis around which the rotating plate rotates is parallel to the workpiece to be cut and the opposite surfaces of the two adjacent support plates. When the rotating plate rotates to be parallel to the workpiece to be cut, the frame, the rotating plate and the clamping plate form a placement slot 1, and the movable frame, the rotating plate and the clamping plate form a placement slot 2. The clamping plate moves in a direction close to the support plate, so that the placement slot 1 and the placement slot 2 clamp and fix the two ends of the workpiece to be cut.

[0019] The spacing between placement slot one and placement slot two can be changed, so that the present invention can cut workpieces of various sizes to be cut; the rotating plate can be rotated to be perpendicular to the cutting workpiece, making it convenient to place the workpiece to be cut between the two clamping plates; the clamping plate can move in a direction perpendicular to the workpiece to be cut, changing the size of placement slot one and placement slot two, so that the present invention can clamp workpieces of different thicknesses to be cut.

[0020] Furthermore, a push plate 1 is provided on the rotating plate, and the push plate 1 is slidably assembled on the rotating plate in a direction parallel to the workpiece to be cut and the opposite surfaces of the two adjacent support plates. When the rotating plate rotates to be parallel to the workpiece to be cut, the push plate 1 is located between the placement groove 1 and the placement groove 2, and the vertical distance between the push plate 1 and the support plate is not greater than the vertical distance between the end face of the placement groove 1 close to the support plate and the support plate.

[0021] Furthermore, the push plate 1 is slidably assembled on the rotating plate. When the rotating plate rotates to be parallel to the workpiece to be cut, the sliding direction of the push plate 1 is perpendicular to the workpiece to be cut.

[0022] When the rotating plate rotates to be parallel to the workpiece to be cut, the push plate 1 can slide in the direction away from the rotating plate under the push of the support plate, ensuring that the push plate 1 can contact the end face of the workpiece to be cut when sliding in the direction parallel to the workpiece to be cut and the opposite surfaces of the two adjacent support plates; the push plate 2, the two clamping plates and the two rotating plates are all in rigid contact with the workpiece to be cut, effectively preventing the workpiece to be cut from moving during the cutting process.

[0023] The beneficial effects of the present invention are:

[0024] When the cutting head cuts the circuit board, the support plate and the pressure plate provide double-sided support for the circuit board to prevent the circuit board from collapsing under the pressure of the cutting head, reduce the vibration generated during the cutting process, and ensure the integrity of the high-value components cut. The end face of the support plate can both support the cutting head and be converted into an inclined surface for high-value components to slide down. It has diverse functions and a high degree of device integration. The setting of the movable frame enables the equipment to clamp workpieces of various sizes to be cut. The push plate 2, two clamping plates and two rotating plates are all in rigid contact with the workpiece to be cut, effectively preventing the circuit board from moving during the cutting process.

The fixed end of the linear actuator 23 is fixedly assembled on the frame 1, and the output end of the linear actuator 23 is fixedly connected to the movable frame 21. The linear actuator 23 drives the movable frame 21 to move so that the L-shaped slot 1 24 and the L-shaped slot 2 25 are moved closer to or away from each other.

The expansion and contraction direction of the elastic member 214 is consistent with the sliding direction of the push plate 1 212. When the rotating plate 26 rotates to be parallel to the bottom surfaces of the L-shaped groove 1 24 and the L-shaped groove 25, the bottom surface of the push plate 1 212 is located below the bottom surfaces of the L-shaped groove 1 24 and the L-shaped groove 25 or is flush with the bottom surfaces of the L-shaped groove 1 24 and the L-shaped groove 25.

[0051] 1. Application in the circuit board installation process: After adjusting the position of the movable frame 21 until the distance between the L-shaped groove 1 24 and the L-shaped groove 25 is adapted to the circuit board to be cut, adjust the linear actuator 5 35 and the linear actuator 7 37 so that the push plate 2 39 and the push plate 3 310 enter the gap between the two adjacent protruding plates 34, adjust the linear actuator 6 36, and increase the distance between the push plate 2 39 and the push plate 310, so that a gap is generated between the support plates 32 for avoiding the movable frame 21, and the linear actuator 8 311 drives the mounting frame 1 31 to move upward, and the movable frame 21 is located in the gap. At this time, the top surface of the support plate 32 and the bottom surfaces of the L-shaped groove 1 24 and the L-shaped groove 25 are at the same horizontal plane.

[0052] 2. Application in the circuit board cutting process: Linear actuator seven 37 drives push plate two 39 and push plate three 310 to move downward, so that push plate two 39 and push plate three 310 are located below the protruding plate 34 in the vertical direction. The linear actuator five 35 is adjusted to drive push plate two 39 and push plate three 310 to move to a predetermined position. The linear actuator seven 37 drives one set of push plate two 39 and push plate three 310 to move upward to the gap between two adjacent protruding plates 34. The linear actuator five 35 and linear actuator six 36 are adjusted to move one set of push plate two 39 and push plate three 310 to the gap between two adjacent protruding plates 34. A predetermined distance is created between them; the other two groups of push plates 2 39 and push plates 3 310 on both sides of one group of push plates 2 39 and push plates 3 310 move, so that the support plates 32 on both sides of one group of push plates 2 39 and push plates 3 310 are tightly fitted, and the support plates 32 close to push plates 2 39 and push plates 3 310 are pressed tightly against push plates 2 39 and push plates 3 310, and a gap is created between two adjacent support plates 32 that fit one group of push plates 2 39 and push plates 310, and the gap is used for the cutting head 42 of the cutting module 4 to pass through in a direction perpendicular to the circuit board. After the high-value component is cut off, the linear actuator eight 311 drives the mounting frame one 31 to move downward, and the high-value component falls on the top surface of the support plate 32 and moves downward synchronously with the support plate 32. The linear actuator eight 311 close to the push plate one 212 drives one end of the mounting frame one 31 close to the push plate one 212 to move downward. The top surface of the support plate 32 is a slope, and the height of the slope gradually decreases from the height of the stop plate 215 to the height of the push plate one 212, and the high-value component slides down along the slope.

The cutting machine includes a cutting head 42 and a driving motor that drives the cutting head 42 to rotate around its own axis. The cutting head 42 is perpendicular to the top surface of the support plate 32 and parallel to the opposite surfaces of the two adjacent support plates 32. The driving mechanism 3 includes a linear actuator 9 43, a linear actuator 10 and a linear actuator 11. The driving direction of the linear actuator 9 43 is the up and down direction, the driving direction of the linear actuator 10 is the front and back direction, and the driving direction of the linear actuator 11 is the left and right direction. The linear actuator 9 43 is an electric push rod or a hydraulic rod, such as Figure 6 As shown, the fixed end of the linear actuator 9 43 is fixedly assembled on the mounting seat 44, and the output end of the linear actuator 9 43 is fixedly connected to the drive motor, as shown in FIG. Figure 7 As shown, linear actuator 10 includes linear motor 1 45 and guide rail 1. Linear motor 1 45 is fixedly mounted on mounting base 44, which in turn is fixedly mounted on mounting bracket 3 46. Linear actuator 11 includes linear motor 2 47 and guide rail 2. Linear motor 2 47 is fixedly mounted on mounting bracket 3 46, which in turn is fixedly mounted on mounting bracket 2 41. Drive mechanism 3 allows cutting head 42 to be positioned at different locations on the circuit board, allowing it to cut high-value components from different locations.

[0054] In order to prevent the flexible circuit board from warping or vibrating during cutting, the support module 3 further includes a pressing plate 48 and a linear actuator 12 49 for driving the pressing plate 48 to move up and down. Figure 6 The pressure plate 48 has a horizontal bottom surface and a through-hole for avoiding the cutting head 42. The pressure plate 48 is located above the frame 1. The linear actuator 12 is an electric push rod or hydraulic rod. The fixed end of the linear actuator 9 43 is fixedly assembled to the mounting plate 2 410. The fixed end of the linear actuator 12 49 is fixedly assembled to the mounting plate 2 410. The pressure plate 48 is fixedly connected to the output end of the linear actuator 12 49. The linear actuator 12 49 drives the pressure plate 48 downward, so that the bottom surface of the pressure plate 48 contacts the top surface of the circuit board and exerts a predetermined pressure on the circuit board. The linear actuator 12 49 contracts, and the linear actuator 9 43 extends. The cutting head 42 moves downward and enters the gap between the support plates 32 to cut the circuit board. During the cutting process, the pressure plate 48 and the support plates 32 clamp the two sides of the circuit board to be cut, offsetting deformation caused by thermal expansion or mechanical pulling during cutting, suppressing high-frequency vibration of the circuit board, and preventing kerf deviation or wavy cutting edges.

[0055] The pressing plate 48 is equipped with a pushing mechanism 5, which includes a pushing plate 4 51 and a linear actuator 13 52. There are two pushing plates 4 51, which are respectively located on both sides of the cutting head 42. Figure 8As shown, a mounting frame 454 is fixedly mounted on the pressure plate 48, a linear actuator 13 52 is an electric push rod or a hydraulic rod, the driving direction of the linear actuator 13 52 is up and down, the fixed end of the linear actuator 13 52 is fixedly mounted on the mounting frame 454, and the output end of the linear actuator 13 52 is connected to the push plate 451, as shown in FIG. Figure 8 As shown, a pressure sensor 53 is installed between the push plate 4 51 and the output end of the linear actuator 13 52. When the bottom surface of the pressure plate 48 is in contact with the top surface of the circuit board, the bottom surface of the push plate 4 51 is also in contact with the top surface of the circuit board.

[0056] The pushing mechanism 5 is used as follows: after the cutting head 42 completes cutting on all sides of the high-value component, the support plate 32 moves down to separate from the circuit board, and the linear actuator thirteen 52 is extended. When the linear actuator thirteen 52 is extended by a predetermined distance and the pressure value detected by the pressure sensor 53 is always zero, it proves that the high-value component has moved down to the bottom of the circuit board with the support plate 32; the linear actuator thirteen 52 is extended by a predetermined distance, but the pressure sensor 53 detects that the pressure value increases and then becomes zero, which proves that there is a slight connection between the high-value component and the circuit board; the pressure sensor 53 detects that the pressure value increases to a predetermined value and lasts for a predetermined time, which proves that the high-value component and the circuit board are still in a fixed connection state. At this time, the equipment needs to be stopped and repaired.

[0057] When using the present invention to cut flexible circuit boards:

[0058] 1. Adjust the linear actuator 1 23 to change the position of the movable frame 21 so that the distance between the L-shaped slot 1 24 and the L-shaped slot 2 25 matches the circuit board;

[0059] 2. Adjust linear actuators 5 35 , 6 36 , and 7 37 to create a gap between support plates 32 to allow for clearance of movable frame 21 . Linear actuator 8 311 drives mounting frame 1 31 upward, positioning movable frame 21 within the gap. The top surface of support plate 32 is flush with the bottom surfaces of L-shaped slots 1 24 and 25 .

[0060] 3. Place the circuit board between L-shaped slot 1 24 and L-shaped slot 2 25. Linear actuator 210 drives rotating plate 26 to rotate until it is parallel to the bottom surfaces of L-shaped slot 1 24 and L-shaped slot 25. The bottom surface of push plate 1 212 is in contact with the top surface of support plate 32. Linear actuator 4 211 drives push plate 1 212 to move toward stop plate 215. The front and rear sides of the circuit board are in contact with the side surfaces of stop plate 215 and push plate 1 212 respectively. Linear actuator 3 27 drives clamping plate 22 downward so that the bottom surface of rotating plate 26 is in contact with the top surface of the circuit board. The circuit board is fixedly mounted on frame 1 and movable frame 21.

[0061] 4. Adjust linear actuator five 35, linear actuator six 36, and linear actuator seven 37 so that push plates two 39 and push plates three 310 move between two adjacent protruding plates 34, creating a gap between support plates 32 corresponding to the circuit board cutting position. Adjust linear motor one 45 and linear motor two 47 so that the cutting head 42 moves to just above the circuit board cutting position. Linear actuator nine 43 drives the cutting head 42 and pressure plate 48 downward, so that the pressure plate 48 contacts the top surface of the circuit board. Adjust linear actuator nine 43 and linear actuator twelve 49 so that the cutting head 42 penetrates the circuit board downward and enters the gap. During the downward movement of the cutting head 42, the pressure plate 48 always maintains a predetermined pressure on the circuit board.

[0062] 5. Linear actuator nine 43 drives the cutting head 42 and pressure plate 48 upward to above the circuit board. Linear actuator five 35, linear actuator six 36, and linear actuator seven 37 are adjusted to create a gap between the support plate 32 corresponding to the next cutting position on the circuit board. Linear motor one 45 and linear motor two 47 are adjusted to move the cutting head 42 to just above the next cutting position on the circuit board. Linear actuator nine 43 and linear actuator twelve 49 are adjusted to allow the cutting head 42 to penetrate the circuit board downward and enter the gap. This process is repeated repeatedly to complete cutting at all cutting positions corresponding to the gap.

[0063] 6. Linear actuator 3 27 drives the clamping plate 22 upward, and linear actuator 4 211 drives push plate 1 212 to move away from the stop plate 215. Adjust linear actuator 210 so that the rotating plate 26 rotates to be perpendicular to the bottom surfaces of L-shaped slot 1 24 and L-shaped slot 2 25. Remove the circuit board and rotate it horizontally 90 degrees. Adjust linear actuator 1 23 so that the distance between L-shaped slot 1 24 and L-shaped slot 25 matches the rotated circuit board. Referring to step 3, fix the rotated circuit board to the frame 1 and the movable frame 21.

[0064] 7. Referring to steps 4 and 5, the rotated circuit board is cut. Each high-value component needs to be cut four times before it can be removed. After the high-value component is cut for the fourth time, the linear actuator 8 311 drives the mounting frame 1 31 to move downward. The high-value component falls on the top surface of the support plate 32 and moves downward synchronously with the support plate 32. The linear actuator 8 311 close to the push plate 1 212 drives one end of the mounting frame 1 31 close to the push plate 1 212 to move downward. The high-value component slides along the top surface of the support plate 32 and is collected by the staff. During the process of the high-value component moving downward and sliding, the linear motor 1 45, the linear motor 2 47, the linear actuator 5 35, the linear actuator 6 36 and the linear actuator 7 37 are adjusted synchronously so that the gap between the cutting head 42 and the support plate 32 corresponds to the next cutting position. After the high-value component slides down, the linear actuator 8 311 drives the support plate 32 to fit the bottom surface of the circuit board again for the next cutting until all the high-value components are cut off.
