Abstract
Description
Technical Field
[0001] This invention relates to the field of magnetic core processing technology, and in particular to a high-frequency soft magnetic ferrite core injection molding blanking machine. Background Technology
[0002] After injection molding, the magnetic core remains connected to the spool (the excess portion remaining on the core body after molding), see... Figure 1 As shown, a product consists of four magnetic cores and a connected shank, the shank of which needs to be removed. Because the magnetic cores are brittle, ordinary stamping or vibration separation methods can cause damage or microcracks, resulting in defective products. Therefore, manual breaking and rearranging of the cores is necessary.
[0003] The current main solution is to manually break the material handle and place the material after the magnetic core has cooled down. This is inefficient and labor-intensive. In addition, repetitive manual labor can easily lead to fatigue. Furthermore, it is impossible for workers to record the production information of each product, making it difficult to trace the root cause when quality problems occur. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this invention proposes a high-frequency soft magnetic ferrite core injection molding blanking machine, which is more efficient, thereby increasing production capacity, reducing labor costs, and shearing simultaneously with the upper and lower blades to prevent uneven stress on the product, which could lead to breakage or hidden cracks, thus improving product quality.
[0005] The technical solution adopted in this invention is: A high-frequency soft magnetic ferrite core injection molding machine includes a frame, a material frame platform for placing material frames, several layers of receiving plates placed inside the material frames, and the outer side of the material frame platform capable of docking with a material cart. A material tray lifting mechanism for pulling out the receiving plates inside the material frame platform is installed on the inner side of the material frame platform. A material shank shearing mechanism is provided on one side of the material tray lifting mechanism. A three-axis conveying mechanism is provided on the frame to transport magnetic cores from the material shank shearing mechanism to the receiving plates. A robotic arm for gripping products from the injection molding machine and placing them onto the material shank shearing mechanism is provided on one side of the material shank shearing mechanism. The material shank shearing mechanism includes a base plate. An opposing motion module is installed on the top, on which an upper cutting tool and a lower cutting tool are installed, which drive the clamping or opening action of the cutting shank. A product seat is installed between the upper cutting tool and the lower cutting tool. A guide groove is provided on the bottom plate below the lower cutting tool. The upper cutting tool includes several upper blades, which are mounted on an upper blade holder rod via an upper blade holder. The upper blade holder rod is movably mounted on the opposing motion module. A pressure block that can press the magnetic core during cutting is installed on the upper blade holder rod. A stamping cylinder is provided on the upper blade holder rod to push the shank into the guide groove when the cutting is in place.
[0006] Furthermore, the product holder is mounted on the base plate via an adjustment seat.
[0007] Furthermore, the cutting tool includes a plurality of lower blades, which are mounted on a lower blade holder rod via a lower blade holder, and the lower blade holder rod is movably mounted on an opposing motion module.
[0008] Furthermore, a material stalk drop channel is provided in the middle of the lower cutting tool.
[0009] Furthermore, the material frame platform includes a welding platform, on which a rotary clamping cylinder for locking the material frame is installed. A proximity sensor is installed on the welding platform to sense when the material frame is in position and output an action signal to the rotary clamping cylinder. A buffer pad is provided on the proximity sensor.
[0010] Furthermore, the welding platform is provided with a guide plate on its side for docking with the material cart.
[0011] Furthermore, the material tray lifting mechanism includes a material tray base, which is mounted on a linear module that drives its longitudinal movement. The material tray base is provided with a material plate platform that can connect with each layer of the material frame and then move along the material plate. The material tray base is also equipped with a pull plate that can pull out the material plate from the material frame or push the material plate back into the material frame. The pull plate is connected to a pull plate cylinder, which is mounted on a nut of a pull plate screw. The pull plate screw is connected to a pull plate motor that drives its movement.
[0012] Furthermore, a material tray base is provided on the platform along a lifting guide rail.
[0013] Furthermore, the three-axis conveying mechanism includes an X-axis module mounted on a frame, a Y-axis module that can move along the X-axis mounted on the X-axis module, a Z-axis module that can move along the Y-axis mounted on the Y-axis module, and several flexible grippers that can move along the Z-axis mounted on the Z-axis module. The flexible grippers are in an open gripping manner.
[0014] Furthermore, the flexible gripper is mounted on a gripper holder bracket via a gripper seat, and the gripper holder bracket is movably mounted on the Z-axis module. The gripper holder bracket is equipped with a position sensor for identifying the magnetic core on the product seat.
[0015] The beneficial effects of this invention are: 1. Compared to manually breaking and placing materials, it is more efficient, thereby increasing production capacity and reducing labor costs.
[0016] 2. The upper and lower cutting blades cut simultaneously to prevent uneven stress on the product, which could lead to breakage or hidden cracks, thus improving product quality. Attached Figure Description

[0035] The present invention will be further described below with reference to specific embodiments, but the invention is not limited to these specific embodiments. Those skilled in the art should recognize that the present invention covers all alternatives, improvements, and equivalents that may be included within the scope of the claims.
[0036] Reference Figure 2 This embodiment provides a high-frequency soft magnetic ferrite core injection molding unloading machine, including a frame 1. The frame 1 is provided with a material frame platform 2 for placing a material frame 3. Several layers of receiving plates 31 are placed inside the material frame 3. The outer side of the material frame platform 2 can dock with a material cart 4. A material tray lifting mechanism 5 for pulling out the receiving plates 31 inside the material frame 3 is installed on the inner side of the material frame platform 2. A material handle shearing mechanism 6 is provided on one side of the material tray lifting mechanism 5. A three-axis conveying mechanism 7 is provided on the frame to transport the magnetic core on the material handle shearing mechanism 6 to the receiving plate 31. A robot arm 8 for clamping products from the injection molding machine 10 is provided on one side of the material handle shearing mechanism 6.
[0037] See Figure 3 In this embodiment, the material frame 3 is open at both the front and the back, and is separated internally by a partition 32. It can accommodate 28 layers of receiving plates 31. Rollers 33 are provided at the bottom, which can be pushed directly from the material cart 4 onto the material frame platform 2.
[0038] See Figures 4-6In this embodiment, the material frame platform 2 includes a welding platform 21. A rotary clamping cylinder 25 for locking the material frame 3 is installed on the welding platform 21. A proximity sensor 22 is installed on the welding platform 21 to sense when the material frame 3 is in position and outputs an action signal to the rotary clamping cylinder 25. A buffer pad 23 is provided on the proximity sensor 22. A guide plate 24 for docking with the material cart 4 is provided on the side of the welding platform 21. The material cart 4 is manually docked with the welding platform 21 via the guide plate 24, and then the material frame 3 on the material cart 4 is pushed into the welding platform 21. After the proximity sensor 22 detects this, the rotary clamping cylinder 25 locks the material frame 3 onto the welding platform 21 to prevent the material frame 3 from moving.
[0039] See Figure 7 , Figure 8 The material tray lifting mechanism 5 described in this embodiment includes a material tray base 57, which is mounted on a linear module 51 that drives its longitudinal movement. The material tray base 57 is provided with a material plate platform 58 that can connect with each layer of the material frame 3 and allow the receiving plate 31 to move along it. A pull plate 54 is mounted on the material tray base 57, which can pull the receiving plate 31 out of the material frame 3 or push the receiving plate 31 back into the material frame 3. The pull plate 54 is connected to a pull plate cylinder 56, which is mounted on a nut of a pull plate screw 53. The pull plate screw 53 is connected to a pull plate motor 55 that drives its movement. A guide rail 52 is provided on the frame 1 along which the material tray base 57 rises and falls. Specifically, a drawer plate 541 and a pusher plate 542 are spaced apart at the front end of the pull plate 54. The width of the pusher plate 542 is greater than the width of the drawer plate 541, and the drawer plate 541 is located in front of the pusher plate 542. Once the material frame 3 is in place, the linear module 51 rises to the 28th layer position of the material frame 3. The pull screw 53 moves forward, driving the pull plate 54 to the material frame 3. The pull cylinder 56 descends, the pull plate 541 engages the receiving plate 31, and the pull screw 53 retracts, thus pulling out the receiving plate 31. The linear module 51 then rises to the receiving position. After the receiving plate 31 is full, the linear module 51 descends to the 28th layer position of the material frame 3. The pull screw 53 moves forward, driving the pull plate 54 forward. The push plate 542 pushes the receiving plate 31 into the material frame 3. The pull plate 54 can continue to operate and remove the receiving plate 31 of the next layer until each receiving plate 31 is full of magnetic cores.
[0040] See Figures 9-11In this embodiment, the robotic arm 8, capable of X-axis, Y-axis, and Z-axis movement, is mounted on the injection molding machine 10. A 90° rotating pick-up fixture 81 is mounted on the lower end of the robotic arm 8. The pick-up fixture 81 clamps the material handle and picks up the part, thus preventing damage to the magnetic core. An L-shaped plate 83 is provided on the back of the pick-up fixture 81. One end of the L-shaped plate 83 is hinged to the robotic arm 8, and the other end is connected to the pick-up cylinder 82 that drives its rotation. The robotic arm 8 picks up the product 9 from the injection molding machine. The pick-up fixture 81 rotates 90 degrees under the action of the pick-up cylinder 82. After the robotic arm 8 moves to the material handle shearing mechanism 6, the pick-up fixture 81 releases, placing the product 9 onto the material handle shearing mechanism 6.
[0041] See Figures 12-14The material handle shearing mechanism 6 described in this embodiment includes a base plate 62. A counter-movement module 61 is mounted on the base plate 62. An upper cutting tool 64 and a lower cutting tool 68 are mounted on the counter-movement module 61, which drive the clamping or opening action of the material handle. A product seat 67 is mounted between the upper cutting tool 64 and the lower cutting tool 68. The product seat 67 is mounted on the base plate 62 via an adjusting seat 70. The product seat 67 is rotatably connected to the adjusting seat 70 relative to the adjusting seat 70. A positioning sensor 66 for sensing the positioning of the product 9 is mounted on the product seat 67. A guide groove 69 is provided on the base plate 62 below the lower cutting tool 68. A waste bin 60 is provided at the outlet of the guide groove 69. The upper cutting tool 64 includes several upper blades 641. The upper blades 641 are mounted on the upper blade holder rod 643 via an upper blade holder 642. The upper blades 641 are mounted on the upper blade holder 642 in an adjustable position. The upper blade holder 642 can rotate relative to the upper blade holder rod 643 to adjust its position. The upper blade holder rod 643 is mounted on the opposing motion module 61 in a longitudinally movable manner. A pressure block 65 is installed on the upper blade holder rod 643 to press the magnetic core during cutting. A stamping cylinder 63 is provided on the upper blade holder rod 643 to push the material handle into the guide groove 69 when the cutting is in place. Similarly, the lower cutting tool 68 includes a plurality of lower blades 681, which are mounted on the lower blade holder rod 683 via a lower blade holder 682. The lower blades 681 are mounted on the lower blade holder 682 in an adjustable position. The lower blade holder 682 can rotate relative to the lower blade holder rod 683 to adjust its position. The lower blade holder rod 683 is mounted on the opposing motion module 61 in a longitudinally movable manner. A material shank discharge channel 684 is provided in the middle of the lower cutting tool 68. Specifically, the opposing motion module 61 in this embodiment includes a bidirectional screw 611, with opposite threads on the upper and lower parts. The upper cutting tool 64 is mounted on the upper part of the bidirectional screw 611 via a slider, and the lower cutting tool 68 is mounted on the lower part of the bidirectional screw 611 via a slider. The bidirectional screw 611 is connected to a drive motor 612 that drives its rotation. Thus, when the drive motor 612 rotates, the upper cutting tool 64 and the lower cutting tool 68 move in opposite directions to clamp the cutting shank, or move in opposite directions to open. In this embodiment, the upper and lower blades are correspondingly arranged, matching the number of magnetic cores. The pressure block 65 is made of soft material, also matching the number of magnetic cores, and will not damage the magnetic cores.The robotic arm 8 removes the product 9 from the injection molding machine 10 and places it into the product holder 67. At this time, the upper cutting blade 64 and the lower cutting blade are in an open state. After the positioning sensor 66 detects that the product 9 has been placed in, the opposing motion module 61 drives the upper and lower cutting blades to perform a clamping action, separating the magnetic core of the product 9 from the material handle. The cutting process will generate cutting force, and the product may tilt to one side. At this time, the pressure block 65 will hold the magnetic core in place, keeping it in the product holder 67. After the cutting is in place, the stamping cylinder 63 extends, pushes the material handle downward and then retracts. The opposing motion module 61 drives the upper and lower cutting blades to perform an opening action, completing the separation of the magnetic core and the material handle. The material handle falls into the waste bin 60 along with the guide chute 69.
[0042] See Figure 15 , Figure 16 The three-axis handling mechanism 7 described in this embodiment includes two parallel X-axis modules 71 mounted on the frame 1. A Y-axis module 72, movable along the X-axis, is mounted on each X-axis module 71. A Z-axis module 73, movable along the Y-axis, is mounted on each Y-axis module 72. Several flexible grippers 74, movable along the Z-axis, are mounted on each Z-axis module 73. The flexible grippers 74 are designed for open-type gripping. Each flexible gripper 74 is mounted on a gripper holder bracket 76 via a gripper seat 75. The gripper seat 75 is rotatably connected to the gripper holder bracket 76 for adjusting the position of the flexible grippers 74. The gripper holder bracket 76 is movably mounted on the Z-axis module 73. A position sensor 77 is mounted on the gripper holder bracket 76 to identify the position of the magnetic core on the product holder 67. After the position sensor 77 identifies the position of the magnetic core, the flexible grippers 74 can adjust their position. The number of flexible grippers 74 is the same as the number of magnetic cores. Each module of the three-axis conveying mechanism 7 moves the flexible gripper 74 onto the material handle shearing mechanism 6. After the position sensor 77 detects the magnetic core, the flexible gripper 74 opens after being ventilated, fixing the magnetic core in the middle. Then, under the joint action of each module, the four magnetic cores are placed onto the receiving plate 31 in sequence.
[0043] See Figure 17 In use, the present invention involves manually docking the material cart 4 with the material frame platform 2, then pushing the material frame 3 on the material cart 4 into the material frame platform 2. Upon detection by the proximity sensor 22, the rotating clamping cylinder 25 locks the material frame 3 onto the material frame platform 2. The material tray lifting mechanism 5 rises to the material frame layer 28, extracts the receiving plate 31, and rises to the receiving position. The robotic arm 8 grips the product 9 onto the material handle shearing mechanism 6, shearing the product 9 to separate the material handle, which falls into the waste bin 60 along with the guide chute 69. The three-axis conveying mechanism 7 grips the magnetic core and places it on the receiving plate 31. Once the receiving plate 31 is full, it is returned to the material frame 3, and then another layer of receiving plates 31 is extracted. When the material frame 3 is full, it is pushed back to the material cart 4 and an empty material cart is replaced.
[0044] Compared to manual breaking and placing of materials, this invention is more efficient, thereby increasing production capacity and reducing labor costs. Simultaneous shearing by the upper and lower cutting blades prevents uneven stress on the product, which could lead to breakage or microcracks, thus improving product quality.
