[0002] In the modern electronic manufacturing industry, magnetic rings, as key electronic components, are widely used in transformers, inductors and filters, etc., and their performance directly affects the quality and stability of electronic products. With the progress of science and technology, electronic products tend to be smaller and more powerful, and the requirements for magnetic ring assembly precision and quality are becoming increasingly stringent. Under this background, to meet the specific electromagnetic performance requirements, some magnetic rings use brittle materials, such as ferrite magnetic rings, which have advantages such as high magnetic permeability and low hysteresis loss, but due to their brittleness, they are easily damaged during assembly.

[0003] However, the magnetic ring assembly machines on the market today aim to improve assembly efficiency and automation, but they cannot effectively detect brittle magnetic rings when assembling them. Due to the lack of detection means, it is difficult to determine whether brittle magnetic rings have been damaged during transportation, feeding and assembly operations. If these brittle magnetic rings with hidden damage are assembled, even if the assembly is completed, the product cannot meet the expected electromagnetic performance indicators. At the same time, the product may gradually expand due to the influence of current, temperature changes or mechanical vibration during the use of the electronic product, eventually causing the performance of the magnetic ring to deteriorate or even fail, seriously threatening the reliability and service life of the electronic product.

[0058] As shown in the figure, Figures 4-6 The weighing detection assembly 43 includes an electronic scale 432 and a weighing platform 436, the inside top of the detection frame 41 is fixedly connected with a support 431, two groups of air cylinders 433 and four groups of limiting columns 435, the two groups of air cylinders 433 are located at the center of the four groups of limiting columns 435, the support 431 is located between the two groups of air cylinders 433, and the electronic scale 432 is fixed at the top of the support 431;

[0060] In actual operation, when the cylinder one 433 is in the contraction state, the bottom of the lifting platform 434 is lower than the top of the electronic scale 432, that is, the electronic scale 432 is located in the weighing groove 437, at this time the electronic scale 432 is in contact with the weighing platform 436 and the weighing platform 436 is separated from the weighing groove 437, so that the electronic scale 432 can weigh the components on the weighing platform 436, and this state is called the weighing detection state of the weighing detection assembly 43; when the cylinder one 433 is elongated, the cylinder one 433 lifts the lifting platform 434, so that the electronic scale 432 is separated from the weighing groove 437 on the lifting platform 434, at this time the weighing platform 436 is in contact with the lifting platform 434 under the action of gravity, that is, the weighing platform 436 is located in the weighing groove 437, and this state is called the non-weighing detection state of the weighing detection assembly 43.

[0061] As shown in Figure 4 、 Figure 5 and Figure 7 , the rotation detection assembly 44 comprises a motor one 442, a rotating table 443, a connecting seat 444, a plurality of springs 445, a pressing block 446 and a pressure sensor 447, the top of the weighing platform 436 is fixedly connected with a support two 441, the motor one 442 is fixed between the support two 441 and the weighing platform 436;

[0062] The output end of the motor one 442 is fixedly connected with the rotating table 443 through the weighing platform 436, the connecting seat 444 is fixed on the top of the rotating table 443, a plurality of through grooves are formed in the connecting seat 444, the center of the connecting seat 444 is fixedly connected with the springs 445, the other end of the springs 445 is fixedly connected with the pressing block 446, the pressing block 446 is arranged in the through groove, and the pressing block 446 is in sliding connection with the connecting seat 444;

[0063] The pressing block 446 is provided with a groove on the periphery, the pressure sensor 447 is arranged in the groove, one side of the pressure sensor 447 is fixedly connected with the pressing block 446, and the other side of the pressure sensor 447 is fixedly connected with an elastic pad 448; the pressure sensor 447 is used for detecting the pressure data when the elastic pad 448 contacts the magnetic ring in the rotating state and the pressure data is transmitted to the collection and analysis module, and the collection and analysis module analyzes whether the magnetic ring has internal defects according to the pressure data;

[0065] In actual operation, when the weighing detection component 43 is in a non-weighing detection state, and the magnetic ring is fitted onto the connecting seat 444, the motor 442 starts rotating, causing the rotary table 443 and the connecting seat 444 on the rotary table 443 to rotate together. The clamping block 446 is thrown out under centrifugal force, causing the elastic pad 448 to contact and press against the inside of the magnetic ring, causing the magnetic ring to rotate together. The pressure sensor 447 detects the pressure of the magnetic ring during rotation. This state is called the rotation detection state of the rotation detection component 44. When the motor 442 is not started, it is the standby state of the rotation detection component 44. When the weight distribution on the magnetic ring is uneven, such as... Figure 12 As shown, the centrifugal force on the circumference of the magnetic ring deviates when it rotates. For example, if one side of the magnetic ring is heavier than the other, the magnetic ring will tend to tilt towards the heavier side during rotation. Specifically, on the side with the heavier magnetic ring, even if the elastic pad 448 on the pressing block 446 contacts and adheres to the inside of the magnetic ring, or even if it does not contact the inside of the magnetic ring, and the spring 445 is in a significantly stretched state, the pressure value detected by the pressure sensor 447 is small. On the opposite side with the heavier magnetic ring, the elastic pad 448 contacts and adheres to the inside of the magnetic ring, the spring 445 is not significantly stretched, or even in a non-stretched state, and the elastic pad 448 is subjected to the centrifugal force of the magnetic ring, resulting in a large pressure value detected by the pressure sensor 447.

[0066] Specifically, such as Figure 3 As shown, the transfer mechanism 5 includes a gripping component, a defective product recycling transfer component, and a qualified product transfer component. A defective product recycling area is provided on the side of the workbench 11 away from the lifting mechanism 3. The defective product recycling area includes a robot arm and a recycling frame.

The qualified product transfer component is used to transfer the qualified magnetic ring to the assembly mechanism 6, where it is assembled.

[0067] Furthermore, such as Figure 3 As shown, the clamping assembly includes a mobile carrier 51 and a material picking part 52. The material picking part 52 is fixed to the output end of the mobile carrier 51. The mobile carrier 51 is a two-dimensional mobile carrier used to drive the material picking part 52 to move up and down and left and right. It can be driven by a cylinder. The material picking part 52 is a material picking device driven by a motor.

[0068] The defective product recycling and transfer assembly includes a second mobile carrier 53, which is equipped with a first limit bracket 54. The second mobile carrier 53 is a linear moving carrier.

[0069] The qualified product transfer and transport assembly includes a limiting support two 55, a conveying belt 56, and a gripper two 58. The limiting support two 55 is fixed to the top of the workbench 11. The limiting support two 55 is provided with the conveying belt 56 away from the detection mechanism 4. The conveying belt 56 is fixed to the side of the moving carrier one 51. The conveying belt 56 is fixedly connected with the moving carrier three 57. The gripper two 58 is fixed to the output end of the moving carrier three 57. The moving carrier three 57 is a two-dimensional moving carrier, which is used to drive the gripper two 58 to move up and down and move forward and backward;

[0070] In actual operation, when the magnetic ring detected by the detection mechanism 4 is a defective product, the moving carrier one 51 drives the material taking part one 52 to move above the detection mechanism 4. The defective product magnetic ring is clamped by the material taking part one 52. Then the material taking part one 52 is driven by the moving carrier one 51 to move above the limiting support one 54. The defective product magnetic ring is placed on the limiting support one 54 by the material taking part one 52. Then the limiting support one 54 is driven by the moving carrier two 53 to move to the defective product recovery area. The defective product magnetic ring is transferred to the recovery area by the mechanical arm of the defective product recovery area.

[0071] Specifically, as shown in Figure 9 and Figure 10 The assembly mechanism 6 includes an assembly table 61, two sets of material taking parts two 63, and two sets of cylinders two 65. The assembly table 61 is arranged outside the frame 1. The top of the assembly table 61 is fixedly connected with a moving carrier four 62, a support frame 64, and a press-fitting seat 67. The moving carrier four 62 is a double-output moving carrier. Two sets of material taking parts two 63 are respectively fixedly connected with the two output ends of the moving carrier four 62. Two sets of cylinders two 65 are respectively fixed to the top of the support frame 64 and the bottom of the assembly table 61. The output end of the cylinder two 65 arranged on the top of the support frame 64 is fixedly connected with a press-fitting head 66. The output end of the cylinder two 65 arranged on the bottom of the assembly table 61 is fixedly connected with the inside of the press-fitting seat 67. The material taking part two 63 close to one side of the support frame 64 is used to clamp the parts of the magnetic ring to be assembled. The material taking part two 63 away from one side of the support frame 64 is used to clamp the magnetic ring on the conveying belt 56.

[0072] In actual operation, the material taking part two 63 close to one side of the support frame 64 clamps the parts of the magnetic ring to be assembled and places them on the press-fitting seat 67. The material taking part two 63 away from one side of the support frame 64 clamps the magnetic ring on the conveying belt 56 and places it on the press-fitting seat 67. Then two sets of cylinders two 65 are started to elongate. The magnetic ring is assembled to the parts of the magnetic ring to be assembled. The assembly of the magnetic ring is completed. Then the assembled magnetic ring can be taken down by the staff or mechanically.

[0073] The assembly method of the intelligent magnetic ring assembly machine:

[0074] Step one: The lifting part 31 starts to lift the storage tray 33 to a set height. The magnetic ring on the storage tray 33 is clamped by the mechanical arm 2 to the detection mechanism 4.

[0075] Step 2: The inspection mechanism 4 inspects the concentricity, weight, and defects of the magnetic rings, and the transfer mechanism 5 classifies the inspected magnetic rings.

[0076] Step 2-1: The visual inspection component 42 detects the concentricity of the magnetic rings and removes magnetic rings with large concentricity deviations;

[0077] Specifically, such as Figure 11 As shown, camera 423 captures an image of the upper surface of the magnetic ring. After the acquisition and analysis module obtains and identifies the maximum thickness 8 and minimum thickness 9 of the magnetic ring, it calculates the actual thickness difference of the magnetic ring. The maximum thickness 8 is denoted as D. max The minimum thickness of 9 is denoted as D. min The actual thickness difference is denoted as ΔD, which is the difference between the maximum thickness of 8 and the minimum thickness of 9, i.e., ΔD = D. max -D min .

[0078] The acquisition and analysis module has a threshold for thickness difference, denoted as A. When the actual thickness difference is greater than the threshold, it indicates that the thickness deviation of the magnetic ring is large. This can easily cause significant pressure fluctuations during subsequent rotation detection and will also affect the normal assembly quality. The acquisition and analysis module determines that the magnetic ring is a defective product.

[0079] When ΔD≤A, the thickness of the magnetic ring is uniform and the concentricity is high. When ΔD=0, it is an ideal state. Further testing and judgment will be carried out.

[0080] When ΔD>A, the magnetic ring has a large thickness deviation and low concentricity, indicating poor production quality. The acquisition and analysis module judges it as a defective product, and the defective product recycling and transfer component of the transfer mechanism 5 performs defective product recycling processing.

[0081] Step 2-2: Weighing and detection component 43 detects the weight of the magnetic ring and removes magnetic rings with abnormal weight;

[0082] Specifically, the weighing detection component 43 is controlled to be in the weighing detection state, the electronic scale 432 weighs the components on the weighing platform 436, and the acquisition and analysis module obtains the actual weight of the magnetic ring, which is recorded as g.

[0083] The data acquisition and analysis module has a magnetic ring weight range set within it. The magnetic ring weight range is [G1, G2], where G1 is the minimum weight of a standard magnetic ring and G2 is the maximum weight of a standard magnetic ring. When the actual weight of the magnetic ring is not within this range, the data acquisition and analysis module determines that the magnetic ring is defective.

[0084] When g∈[G1, G2], the weight of the magnetic ring is within the standard weight range, and subsequent detection and judgment can continue.

[0085] When g does not belong to the interval [G1, G2], the weight deviation of the magnetic ring is large, when g>G2, there is a large adherent on the magnetic ring; when gG1, the magnetic ring has defects or bubbles or uneven density inside, and the collection and analysis module judges it as a defective product, which is recycled by the defective product recycling and transferring assembly of the transferring mechanism 5.

[0086] It should be noted that since the weighing platform 436 is provided with the rotation detection assembly 44, and the structure and weight of the rotation detection assembly 44 are certain, the weight obtained by the electronic scale 432 is the weight of the magnetic ring after removing the weight of the weighing platform 436 and the rotation detection assembly 44; the electronic scale 432 is a high-precision weighing device.

[0087] Steps two to three: the rotation detection assembly 44 detects the dynamic pressure of the magnetic ring, and removes the magnetic ring with internal defects;

[0088] Specifically, the rotation detection assembly 44 is in a rotation detection state, and the pressure values of the magnetic ring during rotation are detected by the plurality of pressure sensors 447, and the actual pressure detected by the plurality of pressure sensors 447 and the maximum deviation of the actual pressure are obtained by the collection and analysis module, the actual pressure is denoted as f i , the maximum deviation of the actual pressure is denoted as Δf, i is the serial number of the pressure sensor 447, i∈[1, n], n is the total number of the pressure sensor 447, that is, the number of the through slots formed on the connecting seat 444, and also the number of the abutting blocks 446, the maximum deviation of the actual pressure is the maximum difference of the pressure values detected by the plurality of pressure sensors 447, so , i[1, n].

[0089] The collection and analysis module is provided with a pressure deviation value, denoted as ΔF, which is used to reflect whether the rotation detection pressure deviation is obvious. If the pressure deviation is large, the weight distribution of the magnetic ring is uneven, the properties of the magnetic ring are poor, and the normal assembly after use is easy to be affected, and the collection and analysis module judges that the magnetic ring is a defective product.

[0090] When Δf<ΔF, , the pressure deviation is small, the weight distribution of the magnetic ring is uniform, there is no internal bubble or uneven density, and when Δf=0, it is an ideal state, which can be normally assembled subsequently, and the magnetic ring is clamped to the qualified product transfer and assembly assembly by the clamping assembly of the transferring mechanism 5, and then transferred to the assembly mechanism 6 by the qualified product transfer and assembly assembly;

[0091] When Δf>ΔF, , the pressure deviation is large, the weight distribution of the magnetic ring is uneven, and there may be bubbles, uneven density, etc. inside the magnetic ring, and the collection and analysis module judges it as a defective product, which is recycled by the defective product recycling and transferring assembly of the transferring mechanism 5.

[0092] Step three: the assembly mechanism 6 assembles the qualified magnetic ring to the part to be assembled.

[0093] Through the above steps, the visual inspection, weighing and dynamic pressure detection are combined to realize multi-dimensional detection mode, reduce the missed detection rate in the magnetic ring assembly process, and avoid the assembly of magnetic rings with quality defects, thereby improving the reliability and service life of electronic products.
