Description

TECHNICAL FIELD

[0001] The application relates to the technical field of inductors, and in particular to an inductor production process. BACKGROUND

[0002] The integrally-formed inductor has the advantages of convenient preparation, miniaturization, strong anti-electromagnetic interference performance, low noise and high frequency, and has been widely applied.

[0003] At present, a Chinese patent with the publication number CN120089496A discloses a preparation method of an inductor, which comprises the following steps: S1, preparing a conductor, the conductor having electrically connected first and second pins; S2, preparing a first magnet, the first magnet being provided with a protruding column and a containing groove arranged around the outer periphery of the protruding column; S3, placing the first magnet in a hot-pressing mold, and then placing the conductor in the hot-pressing mold to assemble the conductor with the first magnet to obtain an assembly; S4, preparing a second magnet, and placing the second magnet in the hot-pressing mold to hot-press the assembly together; S5, removing the hot-pressing mold to obtain an initial inductor; wherein the conductor is located in the containing groove, and the first and second pins are exposed outside the initial inductor; S6, performing roll-spraying treatment on the surface of the initial inductor to prepare an insulating layer; S7, stripping the insulating layer at the first and second pins to expose the first and second pins; S8, performing electroplating treatment at the first and second pins to prepare an electroplating layer, and obtaining the inductor.

[0004] Because the inductor is manufactured in batches during processing, the stripping time is determined when the insulating layer is stripped; therefore, when the initial inductor is subjected to roll-spraying treatment and the prepared insulating layer has a relatively large thickness, the subsequent stripping effect is poor, and the first or second pin still has the insulating layer, which causes poor electroplating effect during subsequent electroplating, and the prepared inductor product is unqualified, and the unqualified product can only be discarded, but the resources used during electroplating and stripping are wasted. SUMMARY

[0005] In order to save resources, the application provides an inductor production process.

[0006] The inductor production process provided by the application adopts the following technical scheme:

[0007] The inductor production process comprises the following steps: S1: cold pressing to form a T-CORE and a U-CORE; S2: winding an enameled wire on the T-CORE to form a first semi-finished product; S3: assembling the first semi-finished product and the U-CORE together by hot pressing to form a second semi-finished product; S4: performing roll spraying treatment on the surface of the second semi-finished product, so that the surface of the second semi-finished product is formed with an insulating layer, and the second semi-finished product with the insulating layer is a third semi-finished product; S5: detecting the thickness of the insulating layer of the third semi-finished product, and removing the third semi-finished product with the insulating layer thickness not meeting the standard, and the third semi-finished product with the insulating layer thickness meeting the standard is a fourth semi-finished product; S6: performing paint stripping treatment on the fourth semi-finished product, so that the pins in the fourth semi-finished product are exposed, and the fourth semi-finished product with the exposed pins is a fifth semi-finished product; S7: detecting the fifth semi-finished product, removing the fifth semi-finished product with poor paint stripping effect, and leaving the fifth semi-finished product with good paint stripping effect; S8: performing electroplating treatment on the fifth semi-finished product with good paint stripping effect to form an inductor final product; and S9: testing the inductor final product, and packaging the inductor final product meeting the test.

[0008] By adopting the above technical scheme, after roll spraying, detection is performed, so that only the semi-finished product with the insulating layer thickness meeting the standard can be subjected to paint stripping treatment, thereby reducing the phenomenon of paint stripping operation on the semi-finished product with the insulating layer thickness not meeting the standard, and the semi-finished product without paint stripping treatment does not need to be subjected to electroplating treatment, so that the waste of paint stripping resources and electroplating resources can be reduced; and after paint stripping, detection is performed again, so that the fifth semi-finished product with poor paint stripping effect does not need to be subjected to electroplating treatment, and the waste of electroplating resources can be reduced; therefore, the inductor production process provided by the application can reduce the waste of resources, and achieve the effect of saving resources.

[0009] Optionally, the step S5 comprises: S51, taking any one pair of opposite side walls of the three pairs of opposite side walls of the third semi-finished product as a first target side wall, detecting the thickness of the insulating layer of the first target side wall of the third semi-finished product by using the first detection and rejection device, and rejecting the third semi-finished product with the insulating layer thickness greater than the standard thickness and the third semi-finished product with the insulating layer thickness less than the standard thickness by using the first detection and rejection device, and the third semi-finished product with the insulating layer thickness meeting the standard thickness after the detection is a first intermediate product; S52, taking any one pair of opposite side walls of the two pairs of opposite side walls of the first intermediate product which have not been detected as a second target side wall, detecting the thickness of the insulating layer of the second target side wall of the first intermediate product by using the second detection and rejection device, and rejecting the first intermediate product with the insulating layer thickness greater than the standard thickness and the first intermediate product with the insulating layer thickness less than the standard thickness by using the second detection and rejection device, and the first intermediate product with the insulating layer thickness meeting the standard thickness after the detection is a second intermediate product; S53, taking the pair of opposite side walls of the second intermediate product which have not been detected as a third target side wall, detecting the thickness of the insulating layer of the third target side wall of the second intermediate product by using the third detection and rejection device, and rejecting the second intermediate product with the insulating layer thickness greater than the standard thickness and the second intermediate product with the insulating layer thickness less than the standard thickness by using the third detection and rejection device, and the second intermediate product with the insulating layer thickness meeting the standard thickness after the detection is a fourth semi-finished product.

[0010] By adopting the above technical scheme, although the insulating layer of the pin side wall will affect the subsequent paint stripping, the insulating layer thickness of the side walls at other positions will cause the specifications to be inconsistent, and the inductance exceeding the specifications will affect the later installation and use; moreover, when the insulating layer thickness at other positions is inconsistent, the subsequent paint stripping position will deviate, and the pins cannot be exposed; therefore, the three pairs of side walls are detected, the insulating layer thickness of all the side walls meets the required specifications, and then the paint stripping operation is performed, so as to reduce the phenomenon of paint stripping resource waste.

[0011] Optionally, the step S51 comprises: S511, taking any one pair of opposite side walls of the three pairs of opposite side walls of the third semi-finished product as a first target side wall; S512, detecting the thickness of the insulating layer of the first target side wall of the third semi-finished product by using the first detection and rejection device, and rejecting the third semi-finished product with the insulating layer thickness greater than the standard thickness, and the third semi-finished product with the insulating layer thickness not greater than the standard thickness is a re-inspection product; S513, detecting the thickness of the insulating layer of the first target side wall of the re-inspection product by using the first detection and rejection device, and rejecting the re-inspection product with the insulating layer thickness less than the standard thickness; and the re-inspection product with the insulating layer thickness meeting the standard thickness is a first intermediate product.

[0012] By adopting the above technical scheme, the screening method of thick first and thin later is convenient to operate, and the separate rejection manner can screen out the insulating layer with thick thickness for thinning treatment, and the insulating layer with thin thickness can be subjected to the roll spraying treatment again.

[0013] Optionally, the first detection and removal device comprises a first conveying frame, a first conveying belt, a thick edge detection and removal mechanism and a thin edge detection and removal mechanism, the first conveying belt is arranged on the first conveying frame; the thick edge detection and removal mechanism and the thin edge detection and removal mechanism are both arranged on the first conveying frame; the thick edge detection and removal mechanism is provided in plurality, and at least one of the thick edge detection and removal mechanisms detects one side wall of the first target side wall, and the other thick edge detection and removal mechanisms detect the other side wall of the first target side wall; the thin edge detection and removal mechanism is provided in plurality, and at least one of the thin edge detection and removal mechanisms detects one side wall of the first target side wall, and the other thin edge detection and removal mechanisms detect the other side wall of the first target side wall.

[0014] By adopting the above technical scheme, the third semi-finished product is placed on the first conveying belt of the first conveying frame, and the first conveying belt drives the third semi-finished product to move; then the thick edge detection and removal mechanisms detect the first target side wall of the third semi-finished product, and after the detection is completed, the third semi-finished product with an insulation layer thickness greater than the standard thickness is removed, the third semi-finished product remaining on the first conveying belt is a re-inspection product, and then the thin edge detection and removal mechanism is used to detect the re-inspection product, and the re-inspection product with an insulation layer thickness less than the standard thickness is removed, so that the re-inspection product remaining on the first conveying belt is a first intermediate product, and then the second detection and removal device is used to detect and remove the unqualified first intermediate product; when the thick edge detection and removal mechanism and the thin edge detection and removal mechanism detect and screen the third semi-finished product, the first conveying belt is always moving, and the first conveying belt does not need to be stopped, so that the continuity of detection of the same batch of third semi-finished products can be ensured; and the thick edge detection and removal mechanism and the thin edge detection and removal mechanism can classify unqualified products, reduce subsequent classification time, and thus facilitate the trimming of different types of unqualified products; at present, there are mainly two ways to detect the insulation layer, one is to directly touch the surface to be tested by using a thickness gauge, and this way has large testing workload and low efficiency, and the other is to use an image taking method, but when one side wall of the first target side wall is thin and the other side wall is thick, the image picture taken is the same as that of the normal thickness, so it is also judged as qualified, and therefore the screening accuracy is relatively low, so the first detection and removal device provided in the application has relatively high detection efficiency and high detection accuracy compared with the prior art.

[0015] Optionally, the thick edge detection and removal mechanism comprises a moving block, a first supporting block, an adjusting block, a thick edge detection plate, an adjusting assembly and a first removal assembly, the moving block is slidably arranged on the first conveying frame, the first supporting block is arranged on the moving block, the adjusting block is slidably arranged on the first supporting block, and the thick edge detection plate is arranged on the adjusting block; the adjusting block and the thick edge detection plate are located above the first conveying belt; the moving block, the first conveying frame, the adjusting block and the thick edge detection plate are connected with the adjusting assembly; and the first removal assembly is arranged on the first conveying frame.

[0016] By adopting the above technical scheme, when the thickness of the insulation layer is not less than the standard thickness, the third semi-finished product will not abut against the side wall of the thick edge detection plate close to the feeding end of the first conveying frame; when the thickness of the insulation layer is greater than the standard thickness, the insulation layer on the third semi-finished product will abut against the side wall of the thick edge detection plate close to the feeding end of the first conveying frame, the adjusting assembly drives the moving block to move on the first conveying frame, the first supporting block on the moving block drives the adjusting block to move, the adjusting block will drive the thick edge detection plate to move, so that the thick edge detection plate and the third semi-finished product move synchronously; and when the moving block moves, the adjusting block will move on the first supporting block away from the first conveying belt under the action of the adjusting assembly, and the thick edge detection plate will move on the adjusting block away from the third semi-finished product, so that the thick edge detection plate no longer abuts against the third semi-finished product; then the first removal assembly is started, and the first removal assembly will remove the third semi-finished product with the insulation layer thickness greater than the standard thickness from the first conveying belt.

[0017] Optionally, the first removal assembly comprises a second supporting block, a cylinder and a pushing block, the second supporting block is arranged on the first conveying frame and located on one side of the first conveying belt, the cylinder body is arranged on the second supporting block, and the pushing block is arranged on the piston rod of the cylinder; and a discharging hole is formed in the first conveying frame away from the second supporting block.

[0018] By adopting the above technical scheme, the cylinder is started, the piston rod of the cylinder drives the pushing block to move, the pushing block will push the third semi-finished product on the first conveying belt towards the discharging hole, and the third semi-finished product will fall from the discharging hole.

[0019] Optionally, the thin edge detection and removal mechanism comprises a third supporting block, a thin edge detection plate and a second removal assembly, the third supporting block is arranged on the first conveying frame, and the thin edge detection plate is arranged on the third supporting block and located above the first conveying belt; and the second removal assembly is arranged on the first conveying frame.

[0021] Optionally, the step S7 specifically comprises: detecting the fifth semi-finished product by a fourth detection removing device, and the fourth detection removing device removes the fifth semi-finished product with poor paint stripping effect and leaves the fifth semi-finished product with good paint stripping effect.

[0022] The present application has the following beneficial technical effects:

S52: taking any one pair of opposite side walls of two pairs of opposite side walls that have not been detected in the first intermediate product as a second target side wall, using a second detection and removal device 2 to detect the insulating layer thickness of the second target side wall in the first intermediate product, and using the second detection and removal device 2 to remove the first intermediate product with the insulating layer thickness greater than the standard thickness and the first intermediate product with the insulating layer thickness less than the standard thickness, and the first intermediate product with the insulating layer thickness meeting the standard thickness after detection is a second intermediate product. S53: taking one pair of opposite side walls that have not been detected in the second intermediate product as a third target side wall, using a third detection and removal device 3 to detect the insulating layer thickness of the third target side wall in the second intermediate product, and using the third detection and removal device 3 to remove the second intermediate product with the insulating layer thickness greater than the standard thickness and the second intermediate product with the insulating layer thickness less than the standard thickness, and the second intermediate product with the insulating layer thickness meeting the standard thickness after detection is a fourth semi-product.

[0037] S6: using a laser paint stripping machine to perform paint stripping treatment on the fourth semi-product, so that a pin in the fourth semi-product is exposed, and the fourth semi-product with the exposed pin is a fifth semi-product.

[0038] S7: detecting the fifth semi-finished product by using the fourth detection and rejection device 8, and the fourth detection and rejection device 8 rejects the fifth semi-finished product with poor paint stripping effect and leaves the fifth semi-finished product with good paint stripping effect.

[0039] S8: performing electroplating treatment on the fifth semi-finished product with good paint stripping effect to form an inductor final product.

[0040] S9: testing the inductor final product under the condition of power-on, and packaging the inductor final product that passes the test.

[0041] Reference Figure 1 and Figure 2 , wherein the first detection and rejection device 1 comprises a first conveying frame 4, the first conveying frame 4 is provided with a first conveying belt 5, and a plurality of thick edge detection and rejection mechanisms 6 and a plurality of thin edge detection and rejection mechanisms 7 are sequentially arranged along the movement direction of the first conveying belt 5.

[0042] Reference Figure 2 The thick edge detection and rejection mechanisms 6 are four in the embodiment, and the four thick edge detection and rejection mechanisms 6 are sequentially a first thick edge detection and rejection mechanism 6, a second thick edge detection and rejection mechanism 6, a third thick edge detection and rejection mechanism 6 and a fourth thick edge detection and rejection mechanism 6 along the movement direction of the first conveying belt 5; the first thick edge detection and rejection mechanism 6 and the second thick edge detection and rejection mechanism 6 are both located on one side of the first conveying belt 5, and the third thick edge detection and rejection mechanism 6 and the fourth thick edge detection and rejection mechanism 6 are both located on the other side of the first conveying belt 5.

[0043] The thin edge detection and rejection mechanisms 7 are also four, and the four thin edge detection and rejection mechanisms 7 are sequentially a first thin edge detection and rejection mechanism 7, a second thin edge detection and rejection mechanism 7, a third thin edge detection and rejection mechanism 7 and a fourth thin edge detection and rejection mechanism 7 along the movement direction of the first conveying belt 5; the first thin edge detection and rejection mechanism 7 and the second thin edge detection and rejection mechanism 7 are both located on one side of the first conveying belt 5, and the third thin edge detection and rejection mechanism 7 and the fourth thin edge detection and rejection mechanism 7 are both located on the other side of the first conveying belt 5.

[0044] Therefore, the second semi-finished product is a cuboid, so when the thickness of the insulation layer reaches the standard, the third semi-finished product is also cuboid-shaped. When the third semi-finished product is transferred to the first conveying belt 5 by the mechanical hand, the third semi-finished product is placed at the same position of the first conveying frame 4, so when the third semi-finished product is located on the first conveying belt 5, if the insulation layer on the third semi-finished product meets the standard, the axis of the third semi-finished product located on the first conveying belt 5 along the conveying direction of the first conveying belt 5 will coincide.

[0045] The first thick edge detection and rejection mechanism 6, the second thick edge detection and rejection mechanism 6, the first thin edge detection and rejection mechanism 7 and the second thin edge detection and rejection mechanism 7 detect one side wall of the first target side wall in the third semi-finished product, and the third thick edge detection and rejection mechanism 6, the fourth thick edge detection and rejection mechanism 6, the third thin edge detection and rejection mechanism 7 and the fourth thin edge detection and rejection mechanism 7 detect the other side wall of the first target side wall in the third semi-finished product.

[0046] With reference to Figure 2 and Figure 3 Each thick edge detection and rejection mechanism 6 comprises a moving block 61 slidably connected to the first conveying frame 4, a first supporting block 62 fixedly connected to the moving block 61, a first sliding groove formed in the first supporting block 62 in the vertical direction of the first supporting block 62, an adjusting block 63 slidably connected in the first sliding groove, a second sliding groove formed in the adjusting block 63, and a thick edge detection plate 64 slidably connected in the second sliding groove. The adjusting block 63 and the thick edge detection plate 64 are located above the first conveying belt 5.

[0047] With reference to Figure 3 and Figure 4 Each moving block 61 is provided with an adjusting assembly 65, which comprises a first rack 651 fixedly connected to the first conveying frame 4, an adjusting motor 652 fixedly connected to the moving block 61, a first gear 653 keyed on the output shaft of the adjusting motor 652 and engaged with the first rack 651, a first screw rod 654 rotatably connected in the first sliding groove of the first supporting block 62, the first screw rod 654 penetrating through the adjusting block 63 and being threadedly connected with the adjusting block 63, one end of the first screw rod 654 located in the moving block 61, a second gear 655 keyed on the first screw rod 654 located in the moving block 61 and engaged with the first rack 651, a second screw rod 656 rotatably connected in the second sliding groove of the adjusting block 63, the second screw rod 656 penetrating through the thick edge detection plate 64 and being threadedly connected with the thick edge detection plate 64, a third gear 657 keyed on one end of the second screw rod 656, and a second rack 658 fixedly connected to the first supporting block 62 and engaged with the third gear 657.

[0048] When the thickness of the insulating layer on one side wall of the first target side wall in the third semi-finished product is not greater than the standard thickness, the side wall of the first target side wall in the third semi-finished product does not abut against the side wall of the thick edge detection plate 64 close to the feeding end of the first conveying frame 4.

[0049] When the thickness of the insulating layer on one side wall of the first target side wall in the third semi-finished product is thicker than the standard thickness, the side wall of the first target side wall in the third semi-finished product will abut against the side wall of the thick edge detection plate 64 close to the feeding end of the first conveying frame 4. The adjusting motor 652 is started, and the output shaft of the adjusting motor 652 drives the first gear 653 to rotate. Since the first gear 653 is engaged with the fixed first rack 651, when the first gear 653 rotates, the moving block 61 will move on the first conveying frame 4 and the moving direction is the same as the direction of the first conveying belt 5. The first supporting block 62 on the moving block 61 drives the adjusting block 63 to move, and the adjusting block 63 drives the thick edge detection plate 64 to move, so that the thick edge detection plate 64 moves together with the third semi-finished product. When the moving block 61 moves relative to the first conveying frame 4, the fixed first rack 651 drives the second gear 655 to rotate, the second gear 655 drives the first lead screw 654 to rotate, and the first lead screw 654 drives the adjusting block 63 to slide in the sliding groove of the first supporting block 62. When the adjusting block 63 moves relative to the first supporting block 62, the fixed second rack 658 drives the third gear 657 to rotate, the third gear 657 drives the second lead screw 656 to rotate, and the second lead screw 656 drives the thick edge detection plate 64 to move. In this way, when the thickness of the insulating layer is thicker than the standard thickness, the moving block 61 moves together with the third semi-finished product, and the thick edge detection plate 64 moves, so that the thick edge detection plate 64 no longer abuts against the third semi-finished product.

[0050] Reference Figure 2 and Figure 3 The moving block 61 and the first rejection assembly 66 are sequentially arranged on the first conveying frame 4 in the moving direction of the first conveying belt 5.

[0051] The first rejection assembly 66 comprises a second supporting block 661 fixedly connected to the first conveying frame 4, and a pneumatic cylinder 662 arranged on the second supporting block 661. The cylinder body of the pneumatic cylinder 662 is fixed to the second supporting block 661, and a push block 663 is connected to the piston rod of the pneumatic cylinder 662. The push block 663 has an L-shaped cross section.

[0052] When the thickness of the insulating layer on the first target side wall in the third semi-finished product is thicker than the standard thickness, the pneumatic cylinder 662 is started, and the piston rod of the pneumatic cylinder 662 drives the push block 663 to move. The push block 663 not only blocks the third semi-finished product, but also pushes the third semi-finished product from the first conveying belt 5 to the discharging hole 41 of the first conveying frame 4 and drops from the discharging hole 41. In this way, the third semi-finished product after passing through the four thick edge detection and rejection mechanisms 6 is the re-inspection product.

[0053] When the moving block 61 in the first thick edge detection and rejection mechanism 6 resets, the thick edge detection plate 64 in the second thick edge detection and rejection mechanism 6 can detect the third product behind it. Similarly, when the moving block 61 in the third thick edge detection and rejection mechanism 6 resets, the thick edge detection plate 64 in the fourth thick edge detection and rejection mechanism 6 can detect the third product behind it. Therefore, the phenomenon of reducing the third product missing detection occurs when the first conveying belt 5 is always moving. Or the first thick edge detection and rejection mechanism 6 and the second thick edge detection and rejection mechanism 6 repeatedly detect the same side wall to ensure the accuracy of detection.

[0054] With reference to Figure 2 and Figure 3 The thin edge detection and rejection mechanism 7 includes a third supporting block 71 fixedly connected to the first conveying frame 4, the third supporting block 71 is L-shaped, and a thin edge detection plate 72 is fixedly connected to the third supporting block 71, and the thin edge detection plate 72 is located above the first conveying belt 5. The first conveying frame 4 is provided with a second rejection assembly 73, and the structure of the second rejection assembly 73 is the same as that of the first rejection assembly 66, and the second supporting block 661 in the second rejection assembly 73 is also fixedly connected to the first conveying frame 4. The thin edge detection plate 72 can be provided with a distance sensor to detect the distance between the insulation layer of the re-inspected product and the thin edge detection plate 72.

[0055] The first conveying belt 5 drives the re-inspected product to move, and when the insulation layer thickness of one side wall of the first target side wall in the re-inspected product is less than the standard thickness, the side wall of the first target side wall in the re-inspected product will directly pass through the thin edge detection plate 72 and exist a distance with the thin edge detection plate 72; and then the pushing block 663 in the second rejection assembly 73 pushes the re-inspected product to the discharging hole 41.

[0056] When the insulation layer thickness of one side wall of the first target side wall in the re-inspected product is the standard thickness, the pushing block 663 in the second rejection assembly 73 will not push the re-inspected product to move. The re-inspected product after passing through the four thin edge detection and rejection mechanisms 7 is the first intermediate product.

[0057] With reference to Figure 2The structures of the second detection and removal device 2 and the third detection and removal device 3 are the same as that of the first detection and removal device 1. The first conveying frame 4 in the second detection and removal device 2 can be coaxial with the first conveying frame 4 in the first detection and removal device 1 or have a certain angle with the first conveying frame 4 in the first detection and removal device 1. When the first conveying frame 4 in the second detection and removal device 2 is coaxial with the first conveying frame 4 in the first detection and removal device 1, the first intermediate product is directly transferred from the first conveying frame 4 in the first detection and removal device 1 to the first conveying frame 4 in the second detection and removal device 2. When the first conveying frame 4 in the second detection and removal device 2 has a certain angle with the first conveying frame 4 in the first detection and removal device 1, the first intermediate product is transferred from the first conveying frame 4 in the first detection and removal device 1 to the first conveying frame 4 in the second detection and removal device 2 by the mechanical hand. The first conveying frame 4 in the third detection and removal device 3 and the first conveying frame 4 in the second detection and removal device 2 have the same setting relationship as that of the first conveying frame 4 in the second detection and removal device 2 and the first conveying frame 4 in the first detection and removal device 1.

[0058] The fourth semi-finished product finally output on the first conveying belt 5 in the third detection and removal device 3 is subjected to paint stripping treatment by a subsequent laser paint stripping machine.
