[0004] In the process of implementing this solution, the following problems in the prior art are found to have not been well solved:

[0005] 1. In the grinding of toroidal magnetic cores in the above prior art, only a single magnetic core can be ground at a time, resulting in a slow progress in the process of magnetic core grinding and processing, and low processing efficiency; 2. In addition, after the magnetic core grinding is completed, the ground magnetic core needs to be removed and then a magnetic core to be ground is reinstalled, which increases the workload of the operators and affects the processing efficiency at the same time.

[0017] A surface treatment process for the production of ferrite cores includes the following steps:

[0018] S1. First, through the loading and unloading mechanism, the two movable plates are simultaneously moved in opposite directions to release the positioning of the rotating cylinder, and then the two ends of the rotating cylinder are supported by the support mechanism. Then, the core after grinding at one end of the rotating cylinder is removed, and the annular core to be ground is sleeved into the rotating cylinder from the other end. After the core loading and unloading is completed, the two movable plates are brought closer together by the loading and unloading mechanism to complete the positioning of the rotating cylinder.

[0019] S2. After that, the core sleeved on the rotating cylinder is pushed into the adjacent annular grinding piece under the extrusion of the support mechanism. Then, the outer grinding mechanism rotates the annular grinding piece, and at the same time, the rotating mechanism rotates the spline sleeve, so that the spline sleeve drives the inner grinding plate on the surface of the rotating cylinder to rotate. Since the rotation torques of the annular grinding piece and the rotating cylinder are equal in magnitude and opposite in direction, the core in the annular grinding piece will remain stationary, and the rotation of the annular grinding piece and the inner grinding plate performs a two-way grinding operation on the inner and outer circles of the core.

[0020] S3. During the precision grinding operation of the core, under the cooperation of the feeding mechanism and the outer grinding mechanism, several arc-shaped push frames will push the corresponding positioning rings to achieve intermittent reciprocating movement, and intermittently convey the core being ground in the annular grinding piece. When the core is sequentially conveyed, through the cooperation between the end of the second movable rod and the transmission component, the inner grinding plate automatically releases the contact with the inner wall of the annular core, so as to facilitate the annular grinding piece to drive the internal core to be pushed. After the core is conveyed, the inner grinding plate can lean against the inner wall of the subsequent conveyed core again, so that the inner circle of the corresponding core can be ground again when the rotating cylinder rotates.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the present invention, through the settings of components such as the outer grinding mechanism, the inner grinding mechanism, and the rotating cylinder, while the rotating cylinder drives the inner grinding mechanism to rotate and grind the inner circles of multiple cores, several outer grinding mechanisms simultaneously grind the outer circles of multiple cores. Under the condition that the rotation torques of the annular grinding piece and the rotating cylinder are equal in magnitude and opposite in direction, the core will remain stationary, and the rotation of the annular grinding piece and the inner grinding plate performs a two-way grinding operation on the inner and outer circles of the core. In this way, multiple cores can be ground simultaneously, further improving the grinding efficiency.

[0023] In the present invention, through the settings of components such as the rotating cylinder, the outer grinding mechanism, and the feeding mechanism, the rotating cylinder can guide the conveyed core. Under the cooperation of the outer grinding mechanism and the feeding mechanism, the ground core can be intermittently conveyed. By this way of conveying and grinding the core, the grinding time limit of the core is extended, and the grinding effect is further improved.

[0024] In the present invention, through the arrangement of components such as a rotating drum, a support mechanism, and a movable plate, under the action of the rotating drum, multiple annular magnetic cores can be placed simultaneously for grinding operations. In addition, the ground magnetic cores can be stored at the end of the rotating drum, and the loading and unloading mechanism can move two movable plates relatively or in opposite directions simultaneously. The support mechanism can support and position the rotating drum, facilitating the disassembly and assembly of multiple ferrite magnetic cores on the rotating drum, further reducing the workload of operators and improving the processing efficiency.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a surface treatment device for ferrite core production, including a base 1, on the surface of the base 1, movable plates 2 are symmetrically and slidably installed, between the bottoms of the two movable plates 2, a loading and unloading mechanism 3 is provided, and between the upper ends of the two movable plates 2, a rotating cylinder 4 is movably installed;

[0040] It also includes an external grinding mechanism 6. There are several external grinding mechanisms 6, and several external grinding mechanisms 6 are equidistantly arranged on the surface of the rotating cylinder 4. It should be added here that a plurality of ball bearings are equidistantly installed on the surface of one end of the magnetic core to be ground sleeved on the rotating cylinder 4, which reduces the friction between the magnetic core and the rotating cylinder 4 during the movement of the magnetic core and facilitates the pushing of the magnetic core. A feeding mechanism 8 for conveying the ground magnetic core is arranged between the bottoms of several external grinding mechanisms 6. An internal grinding mechanism 7 for grinding the inner ring of the magnetic core is arranged inside the rotating cylinder 4, and a transmission component 9 is arranged between one side of the internal grinding mechanism 7 and the corresponding external grinding mechanism 6;

[0041] First spline grooves 401 are formed at both ends of the rotating cylinder 4. A spline sleeve 201 is rotatably installed inside the upper end of the movable plate 2. It should be added here that the outer wall of the spline sleeve 201 and the inside of the upper end of the movable plate 2 are rotatably installed through a bearing to improve the rotation stability of the spline sleeve 201. The spline sleeve 201 is matched with the adjacent first spline groove 401. A rotating mechanism 5 for rotating the rotating cylinder 4 is arranged on a set of movable plates 2.

[0042] In this embodiment, as Figures 1 to 12 shown, the loading and unloading mechanism 3 includes positioning sleeves 301. There are two positioning sleeves 301, and the two positioning sleeves 301 are symmetrically and fixedly installed at the bottom of the base 1. A lead screw 302 is rotatably installed between the two positioning sleeves 301. The bottoms of the two movable plates 2 penetrate through the bottom of the base 1 and are threadedly installed on the surface of the lead screw 302. A support mechanism 10 is arranged between one side of the two movable plates 2 and the surface of the base 1.

[0043] It should be added here that the thread directions at the left and right ends of the lead screw 302 are opposite. During the rotation of the lead screw 302, the two symmetrical movable plates 2 move relatively or in the opposite direction at the same time to position the rotating cylinder 4, and at the same time, it is convenient to disassemble and assemble multiple ferrite magnetic cores on the rotating cylinder 4, further reducing the workload of operators and improving the processing efficiency. A handwheel is fixedly installed at one end of the lead screw 302 to facilitate the rotation of the lead screw 302.

[0044] In this embodiment, as Figures 1 to 12As shown in the figure, the support mechanism 10 includes two sliding grooves 1001 symmetrically arranged on the surface of the base 1. A second guide rod 1002 is fixedly installed horizontally inside the sliding groove 1001, and a moving plate 1003 is slidably installed on the surface of the second guide rod 1002. One end of the second guide rod 1002 is sleeved with a fourth spring 1004, and both ends of the fourth spring 1004 are fixedly installed on the inner wall of the sliding groove 1001 and one side of the bottom of the moving plate 1003 respectively. A moving groove 1005 is formed in the middle of the moving plate 1003, and an L-shaped guide rod 1006 is rotatably installed on the moving groove 1005. The top of the L-shaped guide rod 1006 is fixedly installed with a U-shaped frame 1007, and the top of the U-shaped frame 1007 is fixedly connected with an arc-shaped support plate 10071. It should be noted here that the U-shaped frame 1007 is U-shaped, so that the connecting rod 904 can pass through the U-shaped frame 1007 without interference during the movement of the connecting rod 904. A positioning block 1008 is slidably installed on the upper surface of the upper end of the L-shaped guide rod 1006, and the bottom of the positioning block 1008 is fixedly installed on the surface of the base 1. One side of the lower end of the movable plate 2 is fixedly installed with a pressing block 1009, and the pressing block 1009 is placed on one end of the moving plate 1003. A feeding assembly 11 is arranged at the upper end of the other group of movable plates 2.

[0045] During the loading and unloading of the magnetic cores at both ends of the rotating cylinder 4, by rotating the lead screw 302, the two movable plates 2 move in opposite directions. At this time, the pressing block 1009 on one side of the movable plate 2 releases the extrusion of the corresponding moving plate 1003, so that the fourth spring 1004 is elastically reset, pushing the moving plate 1003 to move to the initial position. At the same time, the two movable plates 2 release the insertion of the rotating cylinder 4 at both ends by moving in opposite directions, and the rotating cylinder 4 descends, and its bottom contacts the arc-shaped support plate 10071. The two arc-shaped support plates 10071 play a supporting role on the bottom of the rotating cylinder 4. After the magnetic cores at both ends of the rotating cylinder 4 are loaded and unloaded, the lead screw 302 is rotated in the reverse direction again. At this time, the two movable plates 2 move relatively, so that the pressing block 1009 on one side of the movable plate 2 squeezes the moving plate 1003 to move. At this time, the L-shaped guide rod 1006 can move up and down in the moving groove 1005 on the surface of the moving plate 1003. When the L-shaped guide rod 1006 moves to the higher position of the moving groove 1005, at this time, the centers of the arc-shaped support plate 10071 and the rotating cylinder 4 are on the same horizontal line. At the same time, the spline sleeve 201 at the upper end of the movable plate 2 is just initially inserted into the first spline groove 401 at the end of the rotating cylinder 4. Through the continuous movement of the moving plate 1003, after the spline sleeve 201 is completely inserted into the first spline groove 401 at the end of the rotating cylinder 4, the L-shaped guide rod 1006 moves to the bottom of the moving groove 1005 again, so that the U-shaped frame 1007 drives the arc-shaped support plate 10071 to descend, releasing the contact with the bottom of the rotating cylinder 4, so that the rotating cylinder 4 is not interfered during rotation. It should be noted here that when loading and unloading the magnetic cores at both ends of the rotating cylinder 4, one end of the rotating cylinder 4 can be manually lifted to release the contact with the arc-shaped support plate 10071 for taking out or loading the magnetic cores.

[0046] In this embodiment, as Figures 1 to 12 shown, the material pushing assembly 11 includes fixing blocks 1101. There are two fixing blocks 1101, and the two fixing blocks 1101 are symmetrically and fixedly installed on one side of the upper end of the other group of movable plates 2. A second push rod 1102 is movably penetrated through the middle of the fixing block 1101, and a push plate 1103 is fixedly installed at one end of the second push rod 1102. A fifth spring 1104 is sleeved on the surface of one end of the second push rod 1102, and both ends of the fifth spring 1104 are fixedly installed between the surface of the fixing block 1101 and the surface of the push plate 1103.

[0047] After the positioning ring 601 drives the magnetic core inside the annular grinding member 602 to complete a certain distance of transportation, the fifth spring 1104 pushes the push plate 1103 to contact the side wall of the corresponding magnetic core, so that several magnetic cores to be ground at one end of the rotating cylinder 4 approach the nearest positioning ring 601, facilitating the automatic filling of the magnetic cores when the positioning ring 601 resets.

[0048] In this embodiment, as Figures 1 to 12 shown, the rotating mechanism 5 is composed of a first motor 501, a first gear 502 and a first toothed ring 503. The first motor 501 is fixedly installed on the top of a group of movable plates 2, the first gear 502 is fixedly installed at the output end of the first motor 501, the first toothed ring 503 is fixedly installed on the outer wall of one end of the adjacent spline sleeve 201, and the surface of the first toothed ring 503 meshes with the surface of the first gear 502.

[0049] It should be noted here that the second motor 604 and the first motor 501 are set by parameters to realize the same speed and opposite direction rotation of the annular grinding member 602 and the spline sleeve 201. When the rotation torques of the annular grinding member 602 and the rotating cylinder 4 are equal in magnitude and opposite in direction, the workpiece will remain stationary, and the magnetic core can be ground in both directions;

[0050] During the inner ring grinding of the magnetic core, by starting the first motor 501, the output end of the first motor 501 drives the first gear 502 to rotate, so that the first gear 502 meshes with the first toothed ring 503 fixed on the outer wall of the spline sleeve 201. Since the spline sleeve 201 is inserted into the first spline groove 401 at one end of the rotating cylinder 4, at this time, the spline sleeve 201 drives the rotating cylinder 4 to rotate, so that the inner grinding plate 703 on the rotating cylinder 4 grinds the inner wall of the annular magnetic core.

[0051] In this embodiment, as Figures 1 to 12As shown, the outer grinding mechanism 6 includes a positioning ring 601. The positioning ring 601 is sleeved on the outer wall of the rotating cylinder 4. An annular grinding piece 602 is rotatably installed on the inner ring of the positioning ring 601. It should be noted here that a bearing is rotatably installed between the outer ring of the annular grinding piece 602 and the inner ring of the positioning ring 601 to improve the rotation stability of the annular grinding piece 602. And an annular chamfer is provided on the side of the annular grinding piece 602 facing the magnetic core to be ground. When the annular grinding piece 602 moves back in place, due to the setting of the annular chamfer, it is convenient for the magnetic core to enter the inside of the annular grinding piece 602. And a second toothed ring 603 is fixedly installed on the outer wall of one end of the annular grinding piece 602. A second motor 604 is fixedly installed on the top of the positioning ring 601, and a second gear 605 is fixedly installed at the output end of the second motor 604. The second gear 605 meshes with the second toothed ring 603. The surface of the base 1 is symmetrically and fixedly installed with brackets 606, and a first movable rod 6061 is horizontally slidably installed inside the brackets 606. One side of the first movable rod 6061 is fixedly connected to the outer walls of a plurality of positioning rings 601. A first spring 6062 is sleeved on one end of the first movable rod 6061, and both ends of the first spring 6062 are respectively fixedly installed between the surface of one end of the first movable rod 6061 and the surface of one end of the bracket 606. One end of the transmission component 9 is arranged on the adjacent positioning ring 601.

[0052] During the grinding of the outer ring of the magnetic core, start the second motor 604. The output end of the second motor 604 drives the second gear 605 to mesh with the second toothed ring 603 fixed to one end of the annular grinding piece 602, so that the annular grinding piece 602 rotates inside the positioning ring 601. When the magnetic core is inside the annular grinding piece 602, the annular grinding piece 602 can grind the outer wall of the magnetic core. When the feeding mechanism 8 pushes a plurality of positioning rings 601 to move a certain distance to intermittently convey the magnetic core, after the arc-shaped push frame 806 releases the push on the positioning ring 601, the first spring 6062 is elastically reset under force, driving the first movable rod 6061 to move, so that the first movable rod 6061 drives a plurality of positioning rings 601 to move back in place. During the reset of the positioning ring 601, the annular grinding piece 602 rotatably installed in the positioning ring 601 performs a filling operation on the magnetic core at the corresponding position.

[0053] In this embodiment, as Figures 1 to 12As shown, the inner grinding mechanism 7 includes a second movable rod 701. The second movable rod 701 is slidably installed horizontally inside the rotating cylinder 4. A number of conical blocks 702 are fixedly connected to the surface of the second movable rod 701. It should be noted here that the number of conical blocks 702 corresponds one by one to the number of positioning rings 601. Four pressure rods 704 are equidistantly arranged along the circumference on the surface of the conical block 702. One end of the pressure rod 704 extends to the outside of the rotating cylinder 4. An inner grinding plate 703 is fixedly connected to the end of one end of the pressure rod 704. A second spring 705 is sleeved on the surface of the pressure rod 704, and both ends of the second spring 705 are fixedly installed on the surface of the other end of the pressure rod 704 and the inner wall of the rotating cylinder 4. A limit ring 706 is fixedly installed on the surface of one end of the second movable rod 701. A third spring 707 is sleeved on the surface of one end of the second movable rod 701, and both ends of the third spring 707 are fixedly installed on the surface of one side of the limit ring 706 and the inner wall of the rotating cylinder 4.

[0054] It should be added here that the other end of the pressure rod 704 is provided with an inclined surface that matches the conical surface of the conical block 702. When the second movable rod 701 is squeezed by the first push rod 901, the conical surface of the conical block 702 on the surface of the second movable rod 701 squeezes and pushes the inner grinding plate 703 fixed at the end of the corresponding pressure rod 704 to lean against the inner ring of the magnetic core, which is convenient for the grinding operation of the inner ring of the magnetic core. In addition, four grooves are equidistantly arranged along the circumference in the middle of the outer wall of the rotating cylinder 4. When the inner grinding plate 703 moves closer to the middle of the rotating cylinder 4, the inner grinding plate 703 will move into the grooves.

[0055] In this embodiment, as Figures 1 to 12As shown in the figure, the feeding mechanism 8 includes a mounting frame 801, which is fixedly installed on the surface of the base 1. A rectangular guide groove 8011 is formed on one side of the mounting frame 801. A third motor 802 is fixedly installed on the mounting frame 801. It should be noted that the third motor 802 is a low-speed motor that can drive the connecting plate 803 to rotate slowly. The output end of the third motor 802 is fixedly connected to the connecting plate 803. A guide roller 804 is rotatably installed inside one end of the connecting plate 803. It should be added here that a waist-shaped groove is formed at one end of the connecting plate 803, and the middle part of the guide roller 804 is movably installed in the waist-shaped groove at one end of the connecting plate 803. During the rotation of the connecting plate 803 driven by the third motor 802, the guide roller 804 at one end of the connecting plate 803 can have a certain amount of displacement space, so that the guide roller 804 can move along the track of the rectangular guide groove 8011. One end of the guide roller 804 is fixedly connected to a lifting plate 805, and the other end of the guide roller 804 is rotatably installed inside the rectangular guide groove 8011. A plurality of arc-shaped pushing frames 806 are fixedly installed at equal intervals on the top of the lifting plate 805, and the arc-shaped pushing frames 806 are located on one side of the lower end of the adjacent positioning ring 601. First guide rods 807 are symmetrically and movably penetrated through one side of the lifting plate 805, and the bottoms of the first guide rods 807 are slidably installed on the surface of the base 1. It should be noted that the first guide rods 807 can play a guiding role in the lifting of the lifting plate 805 and improve the stability of the lifting of the lifting plate 805.

[0056] During the intermittent feeding of the polished magnetic core, the output end of the third motor 802 drives the fixed connecting plate 803 to rotate slowly. At this time, the connecting plate 803 drives the guide roller 804 at one end to move along the track of the rectangular guide groove 8011. When the guide roller 804 moves to the upper end side of the rectangular guide groove 8011, the guide roller 804 drives the arc-shaped pushing frame 806 on the lifting plate 805 to rise, so that the arc-shaped pushing frame 806 abuts against one side of the positioning ring 601. During the continuous movement of the guide roller 804, at this time, the guide roller 804 moves horizontally along the upper end of the rectangular guide groove 8011, so that the arc-shaped pushing frame 806 abutting against the positioning ring 601 pushes the positioning ring 601 to move horizontally, thereby completing the feeding of the polished magnetic core by a certain distance, and transporting the magnetic core to the position of the next adjacent inner grinding plate 703 for subsequent re-grinding. By this way, the feeding and grinding of the magnetic core are carried out, so as to extend the grinding time limit of the magnetic core and further improve the grinding effect. When the guide roller 804 continues to move to the lower end side of the rectangular guide groove 8011, the guide roller 804 drives the arc-shaped pushing frame 806 on the lifting plate 805 to descend and releases the extrusion and pushing on the positioning ring 601, so that the positioning ring 601 is reset under the elastic reset of the first spring 6062, which is convenient for the feeding and grinding of the subsequent magnetic core.

[0057] In this embodiment, as Figures 1 to 12As shown in the figure, the transmission assembly 9 includes a first push rod 901. The first push rod 901 is rotatably installed horizontally in the middle of the adjacent spline sleeve 201. It should be noted that the first push rod 901 is rotatably installed in the middle of the adjacent spline sleeve 201 through a bearing. One end of the first push rod 901 is placed at the end of the second movable rod 701. The other end of the first push rod 901 is fixedly connected with a first mounting plate 902, and a spline 9021 is fixedly installed on the surface of the first mounting plate 902. A connecting rod 904 is movably penetrated through the upper ends of a group of movable plates 2, and one end of the connecting rod 904 is fixedly connected with the bottom of the adjacent positioning ring 601. The other end of the connecting rod 904 is fixedly connected with a second mounting plate 903, and a second spline groove 9031 is formed on the surface of one side of the second mounting plate 903. The second spline groove 9031 is matched with the spline 9021.

[0058] During the movement of the positioning ring 601 driven by the arc-shaped push frame 806, the positioning ring 601 drives the connecting rod 904 to move, so that the second mounting plate 903 at the end of the connecting rod 904 releases the extrusion on the first mounting plate 902. The second mounting plate 903 moves away from the movable plate 2, and the second spline groove 9031 releases the insertion of the spline 9021. At this time, the third spring 707 elastically resets, pushing the limit ring 706 on the second movable rod 701 to move, so that the tapered block 702 on the surface of the second movable rod 701 releases the extrusion on the inclined surface of the corresponding pressure rod 704. At the same time, the second spring 705 elastically resets, driving the inner grinding plate 703 to move closer to the second movable rod 701. The inner grinding plate 703 automatically releases the contact with the inner wall of the ring-shaped magnetic core, so as to facilitate the movement of the magnetic core inside the positioning ring 601 driven by the positioning ring 601. When the positioning ring 601 moves in place, the positioning ring 601 drives the connecting rod 904 to move in place again, so that the second mounting plate 903 pushes the first mounting plate 902 on the first push rod 901 to approach the movable plate 2, and the second spline groove 9031 is inserted on the spline 9021, so that the end of the first push rod 901 extrudes the second movable rod 701 to move, so that the tapered block 702 on the second movable rod 701 squeezes and pushes the inner grinding plate 703 to lean against the inner wall of the magnetic core again. After the positioning ring 601 is in place, the inner grinding plate 703 contacts the inner wall of the magnetic core again. During the rotation of the rotating cylinder 4, the inner grinding plate 703 grinds the corresponding inner wall of the magnetic core again, and at the same time, the annular grinding member 602 grinds the outer wall of the magnetic core;

[0059] The outer grinding mechanism 6 and the inner grinding mechanism 7 simultaneously perform grinding operations on multiple magnetic cores, further improving the grinding efficiency.

[0060] In this embodiment, as Figures 1 to 12 shown, a surface treatment process for the production of ferrite magnetic cores includes the following steps:

[0061] S1. First, the loading and unloading mechanism 3 moves two movable plates 2 in opposite directions simultaneously to release the positioning of the rotating cylinder 4. Then, the two ends of the rotating cylinder 4 are supported by the supporting mechanism 10. Next, the magnet core that has been polished at one end of the rotating cylinder 4 is removed, and the annular magnet core to be polished is sleeved in from the other end. After the loading and unloading of the magnet core is completed, the two movable plates 2 are brought closer together by the loading and unloading mechanism 3 to complete the positioning of the rotating cylinder 4.

[0062] S2. After that, the magnet core sleeved on the rotating cylinder 4 is pushed into the adjacent annular grinding piece 602 by the supporting mechanism 10. Then, the outer grinding mechanism 6 rotates the annular grinding piece 602, and at the same time, the rotating mechanism 5 rotates the spline sleeve 201, so that the spline sleeve 201 drives the inner grinding plate 703 on the surface of the rotating cylinder 4 to rotate. Since the rotation torques of the annular grinding piece 602 and the rotating cylinder 4 are equal in magnitude and opposite in direction, the magnet core in the annular grinding piece 602 will remain stationary, enabling the rotation of the annular grinding piece 602 and the inner grinding plate 703 to perform two-way grinding operations on the inner and outer circles of the magnet core.

[0063] S3. During the precision grinding operation of the magnet core, with the cooperation of the feeding mechanism 8 and the outer grinding mechanism 6, several arc-shaped push frames 806 will push the corresponding positioning rings 601 to achieve intermittent reciprocating movement, intermittently conveying the magnet core being ground in the annular grinding piece 602. When the magnet core is being conveyed in sequence, through the cooperation between the end of the second movable rod 701 and the transmission assembly 9, the inner grinding plate 703 automatically releases the contact with the inner wall of the annular magnet core, facilitating the annular grinding piece 602 to drive the internal magnet core for pushing. After the magnet core is conveyed, the inner grinding plate 703 can again lean against the inner wall of the magnet core to be conveyed subsequently, enabling the rotating cylinder 4 to grind the inner circle of the corresponding magnet core again when it rotates.
