Description

Technical Field

[0001] The present invention belongs to the technical field of wire dividing devices, and particularly relates to a device for dividing and housing long and short coils of network filters. Background Art

[0002] A network transformer, also known as a network isolation transformer or a pulse transformer, is an electronic component used for data transmission and signal isolation. It has wide applications in fields such as network communication, industrial control, and power systems. A network transformer includes a core material, a coil structure, an insulating material, pins and welding, shielding, and encapsulation. The core usually uses a ferrite core. The coil can be wound in a single layer or multiple layers. The insulating material is used to ensure electrical isolation between the coils. The pins are made of copper or other conductive materials and are connected to the coils by welding. To reduce electromagnetic interference, some network transformers are designed with a metal shield. The housing can be plastic or metal to protect the internal structure and provide mechanical support.

[0003] The manufacturing process of a network transformer includes core preparation, coil winding, pin welding, insulation treatment, shielding and encapsulation, and testing and aging treatment. According to the design requirements, the primary and secondary coils need to be wound on the core during manufacturing. The winding is usually done manually now, and there are a small number of automated devices dedicated to winding network transformers. The wound coils are welded to the pins to ensure the reliability of the connection and the electrical performance.

[0004] Before winding, it is necessary to comb the winding wires of the winding (the magnetic ring structure after winding on the core), that is, to straighten the corresponding number of winding wires to both sides to form two bundles of wires, and then put them into the plastic case of the network transformer through manual wire division for the process of winding the feet. In this process, during the process of putting the coil into the case, the existing method is to manually sort and divide the coil and then put it into the plastic case. This method of wire sorting, wire dividing, and case loading is not applicable to the automated process, and there is no device or method in the prior art that can sort and divide the coil wires and automatically place the separated winding wires in the plastic case. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a device for dividing and housing long and short coils of network filters, which solves the problems of low efficiency and poor yield of the existing manual wire dividing, wire sorting, and case loading through an automated method.

[0006] The technical solution adopted by the present invention is as follows: In a first aspect, the present invention discloses a device for dividing and housing long and short coils of network filters, which sorts and arranges the coils with winding wires extending outward and then installs them in a plastic case and fixes them to form a semi-finished product of a network filter before winding the feet, including being sequentially arranged in the direction of material transfer: The feeding component transfers the wound coil in the material box to the coil jig through an automatic feeding mechanism for fixation and then transfers it; The wire arranging component receives the coil jig transmitted by the feeding component and straightens the winding wires on the coil on the coil jig outward for wire arrangement; The wire separating component binds the winding wires straightened outside the coil transmitted by the wire arranging component and releases them in sequence from short to long, and separates the winding wires released each time through an air blowing mechanism provided to form a wire separating state; and The casing assembling component places the coil in the wire separating state transmitted by the wire separating component into the plastic shell of the network filter while maintaining the wire separating state.

[0007] Combined with the first aspect, the present invention provides the first implementation manner of the first aspect. The wire separating component includes a wire clamp and an air blowing mechanism. The wire clamp binds the winding wires on both sides of the incoming coil from the root to form a wire bundle and transfers the binding point outward. The air blowing mechanism sprays air flow on the wire bundle so that the winding wires separated from the binding are separated.

[0008] Combined with the first implementation manner of the first aspect, the present invention provides the second implementation manner of the first aspect. The wire clamp has an opening and closing end for clamping the winding wires. The unilateral winding wires are clamped and bound from the root of the winding wires at the coil by the opening and closing end and slide outward along the length direction of the winding wires for clamping.

[0009] Combined with the first implementation manner of the first aspect, the present invention provides the third implementation manner of the first aspect. The wire separating component further includes a wire separator movably arranged relative to the coil. The wire separator has a plurality of wire grooves. When the air blowing mechanism blows the winding wires off the wire bundle, the wire separator displaces to form empty wire grooves with the opening facing the air blowing direction.

[0010] Combined with the first aspect or several implementation manners of the first aspect, the present invention provides the fourth implementation manner of the first aspect. The wire arranging component includes several wire arrangers, and the wire arrangers have clamping ends for binding and straightening the winding wires outward.

[0011] Combined with the first aspect or several implementation manners of the first aspect, the present invention provides the fifth implementation manner of the first aspect. Between the feeding component and the wire arranging component, the coil jig with the coil is transmitted through a conveyor belt provided; Between the wire arranging component and the wire separating component, and between the wire separating component and the casing assembling component, the coil is transmitted through a transfer rack provided.

[0012] Combined with the fifth embodiment of the first aspect, the present invention provides a sixth embodiment of the first aspect. The transfer rack is provided with a whole-line transfer rack and a branch-line transfer rack. The whole-line transfer rack transfers the coils coming out of the wire arranging assembly to the branch-line assembly in a manner of clamping the coil winding wires on both sides as a whole. The branch-line transfer rack separates and clamps the winding wires of the coils in the branch-line state in the branch-line assembly through a plurality of clamping ends and transfers them to the casing assembly.

[0013] Combined with the sixth embodiment of the first aspect, the present invention provides a seventh embodiment of the first aspect. The casing assembly includes a fixing rack for placing the plastic shell fixture. The branch-line transfer rack places the coils in the plastic shells on the plastic shell fixture in a branch-line state for wire pressing and fixing.

[0014] Combined with the first aspect or several embodiments of the first aspect, the present invention provides an eighth embodiment of the first aspect. It further includes a wire stripping assembly arranged at the rear side of the material transfer direction of the casing assembly or the branch-line assembly. The wire stripping assembly has a fixture turning rack for placing the coils or coil fixtures. A laser is provided outside the fixture turning rack. The laser moves towards the surface of the winding wire for burning and wire stripping.

[0015] Combined with the first aspect or several embodiments of the first aspect, the present invention provides a ninth embodiment of the first aspect. It further includes an inspection and packaging assembly arranged at the end of the material transfer direction. The inspection and packaging assembly visually inspects the plastic shells containing the coils and then transfers them after casing.

[0016] The beneficial effects of the present invention are as follows: (1) After fixing the plastic shell of the network filter, the present invention clamps and binds the roots of the wire harnesses on both sides, and then continuously changes the binding position outwards, so that each winding wire of different lengths will be released in turn. During the release process, wire splitting is carried out through a wire splitter, thus achieving an automatic wire splitting effect. (2) By means of air blowing, the present invention can blow the released winding wires out of the wire harness position and change the orientation of their ends, thus achieving a wire splitting effect. Compared with the manual processing method, it has better wire splitting efficiency and less damage to the wire. (3) Through the cooperation of the equipment, the present invention is provided with a fixed wire groove or a wire splitter component in the form of an openable and closable clamping arm, which can guide the blown winding groups into the corresponding areas for limiting, and at the same time, each winding wire can enter an independent wire groove for storage through the displacement of the air blowing mechanism or the displacement of the wire splitter component relative to the air blowing mechanism, so that the position of each winding wire can be positioned for individual winding during subsequent winding. (4) Through the provided movable wire-splitting transfer rack, the present invention can cooperate with the upper and lower technological processes, pick up the already wire-split coils from the position of the previous process for transfer, and directly install the coils into the shell through the wire-splitting transfer rack. At the same time, through the provided wire-splitting fixture, all winding wires are always fixed during the transfer and shell installation processes, keeping them in a wire-split state, and avoiding the displacement of the winding wires during the transfer and shell installation processes, which may affect the subsequent wire-wrapping process. (5) The present invention realizes stable laser skin removal in both steps by two methods, namely, laser skin removal for the coils already installed in the plastic shell and for the winding wires of the coils not yet installed in the plastic shell, providing convenience for the subsequent wire-wrapping process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further explains the present invention in conjunction with the accompanying drawings and specific embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0026] Embodiment 1: This embodiment discloses a device for separating and housing long and short coils of a network filter. It should be noted that the network filter involved in this embodiment is a semi-finished product, and the final product only has a plastic housing. Inside the plastic housing, there are several windings, and each winding has at least two winding wire ends facing outward and with a relatively long length.

[0027] Meanwhile, in this embodiment, the specific use of the semi-finished product is not specifically limited. As long as the structure has such characteristics, the method provided in this embodiment can be used for the pre-wiring operation. For example, a network filter also has the same structural characteristics, but in this embodiment, the network filter is used for reference. It should be emphasized that this embodiment does not involve the specific form, size, and number of winding wires of the specific network filter and winding. In the wiring of the applicable network filter, at least two winding wires must exist on both sides simultaneously, and the length of each winding wire is different.

[0028] Specifically, the long and short wire coil wiring and casing device for the network filter is arranged in sequence along the material transfer direction with a feeding component 1, a wire arranging component 2, a wiring component 3, and a casing component 4. The feeding component 1 fixes the wound coil (with outwardly extending winding wires) to the coil fixture through an automatic feeding mechanism and transfers it to the wire arranging component 2 via a conveyor belt. The wire arranger 8 of the wire arranging component 2 restrains the winding wires at the clamping end and straightens them outward to form a pre-arranged state. The wire clamp 10 of the wiring component 3 clamps the winding wires on both sides from the root of the coil to form a wire bundle, releases the restraint point by moving the wire clamp 10 outward along the length direction of the winding wire, and simultaneously starts the air blowing mechanism to eject air flow, so that the released winding wires are separated in the order of length. The casing component 4 receives the coil in the wired state and presses it into the plastic shell in the plastic shell fixture 13 in the wired state for fixation to form a semi-finished product before winding the feet.

[0029] Among them, the core action chain: coil fixture transfer → wire arranging and straightening → wire clamping and restraint + air blowing for wiring → directional casing, realizing automatic sorting and casing of long and short wires. Among them, the coil fixture with the coil is transmitted between the feeding component 1 and the wire arranging component 2 through the conveyor belt; the coil is transmitted between the wire arranging component 2 and the wiring component 3, and between the wiring component 3 and the casing component 4 through the transfer rack 9.

[0030] Refer to Figures 1-5 , this embodiment optimizes and defines the long and short wire coil wiring and casing device for the network filter in the above implementation manner.

[0031] Among them, the wiring component 3 includes a wire clamp 10 and an air blowing mechanism. The wire clamp 10 binds the winding wires on both sides of the incoming coil from the root to form a wire bundle and transfers the restraint point outward. The air blowing mechanism sprays air flow on the wire bundle so that the released winding wires are separated. The wire clamp 10 has an opening and closing end for clamping the winding wire, and clamps and restrains the single-side winding wire from the root of the winding wire at the coil and slides and clamps it outward along the length direction of the winding wire.

[0032] The wiring component 3 further includes a wire divider movably arranged relative to the coil. The wire divider has a plurality of wire grooves, and when the air blowing mechanism blows the winding wire off the wire bundle, the wire divider displaces to form an empty wire groove with an opening facing the air blowing direction.

[0033] Reference Figure 4 A coil fixture with a vertical plate structure is provided in the middle of the branching assembly 3, and a plurality of grooves for placing the coils are provided on the top end surface of the coil fixture along the length direction.

[0034] Two groups of devices for clamping and dividing wires are symmetrically arranged on both sides of the coil jig. The wire divider is closer to the coil jig, while the wire clamp 10 is farther from the coil jig, wherein the wire divider is lower than the wire clamp 10.

[0035] Not shown in the figure is the air blowing mechanism for separating the wires arranged on the outside of the coil fixture. In this embodiment, it is only necessary to limit the air blowing direction of the air blowing mechanism to the surface of the wire harness. The range of air blowing has a variety of implementation methods, including horizontal line blowing, point blowing and group blowing, as long as the blown gas contacts the surface of the separated winding wire and can blow it open.

[0036] The specific line division method is as follows: First, in the previous process, several coils have been placed on the coil fixture after the wire arrangement, that is, the winding wires on both sides are straightened and placed toward both sides, and there are at least three winding wires on both sides, and they are close to each other. At this time, the equipment is started, and the clamps 10 on both sides that can be displaced relative to the coil fixture are first moved to the side of the plastic shell, and then programmed to move and position through visual inspection or a predetermined appearance position, and at this time, it is determined that the wire harness of the winding wire is in the middle of the clamping of the clamp 10.

[0037] Then, the roots of the winding wire bundles on both sides of the coil are clamped by the wire clamp 10 at the same time, and then the wire clamp 10 is slowly moved toward the outside of the coil.

[0038] During the movement, the shortest winding wires on both sides will break away from the clamp 10. Since the length of each winding wire entering the network filter is a determined parameter, the relative distance between the clamp 10 and the coil can be determined, or the clamp 10 can determine a distance threshold based on the displacement data when the clamp starts clamping. When the distance threshold is reached, it is determined that a winding wire is separated.

[0039] At this time, an external air blowing mechanism is set up to blow air once or multiple times at the center position of the wire harness (i.e., the middle value of the wire harness part containing all winding wires or the end position close to the separated shortest winding wire), and a wire splitter is set in the direction relative to the air blowing, and the air blowing mechanism blows the separated winding wires into the wire slots of the corresponding wire splitters, and after a single blowing, the wire slots are bound and fixed, so that the winding wires in the wire slots are limited, thereby completing a single wire splitting.

[0040] Then, as the wire clamp 10 continues to slide outward, the winding wires that are continuously detached will be blown toward the wire splitter by the air blowing mechanism, and each winding wire will be grabbed and fixed by the wire slot of the wire splitter until the last winding wire is released and blown into the wire slot to complete the wire splitting process.

[0041] It should be noted that the wire clamp 10 in this embodiment is a clamp structure. In order to avoid damage to the wire harness surface during the clamping and sliding process, a relatively smooth nylon material or a rollable pulley material is used to reduce the damage to the wire surface by reducing the sliding friction or changing to a rolling contact method.

[0042] As an implementation method, the blowing method in this embodiment is single-point blowing, and the blowing point moves along with the binding position of the winding wire harness. That is, the air blowing mechanism is movably arranged on a fixed table, or is arranged on the same movable mechanism as the clamp 10, has an initial fixed position, and can move with the clamp 10, so as to follow the separated winding wire for air blowing, and can blow more accurately toward the end of the separated winding wire.

[0043] As an implementation method, during air blowing separation, the winding wires that have been freed from the wiring harness are received at several different positions relative to the winding wire harness. After receiving a single winding wire at the other side of the wiring harness relative to the blowing direction, the blowing direction is changed to the next receiving position to blow air to separate the single winding wire again, until all the winding wires in the wiring harness are individually received and separated.

[0044] In this method, the air blowing mechanism is a mechanism that rotates around the wire harness, and a wire divider with a row of wire slots is set below the wire harness. By continuously changing the blowing angle of the air blowing mechanism, the winding wire is blown into wire slots at different positions. This method can adopt a fixed guide wire slot structure, and there is no need to set a movable wire slot structure for limiting each winding wire. The structure is relatively simple and the cost is low.

[0045] Further, refer to Figure 2 and Figure 3 The loading component 1 includes a material trough, a feeding rack 7 and a jig lifting rack. There are multiple coil jigs, all of which are placed in the material trough. The jig lifting rack, which is set on the feeding rack 7 and moves, lifts the coil jig from the material trough and moves it to the wire management component 2.

[0046] The wire management assembly 2 includes a plurality of wire managers 8. After the coil fixture enters the wire management assembly 2, the wire managers 8 arranged on both sides of the coil fixture bind the winding wire at the root of the coil and straighten it outward to form two symmetrical winding wires on both sides of the coil.

[0047] The steps for using the above-mentioned automated equipment for feeding and dividing the line are as follows: First, two sets of coil fixtures are selected and lifted from the material trough through the fixture lifting frame in the feeding component 1. Then, after the coil fixtures are lifted by the fixture lifting frame, they are transferred to the wire arranging component 2, and several coils in the material package are placed in the grooves of the coil fixtures through an automated transfer device on the coil fixtures taken out from the material trough, so that the coil fixtures entering the wire arranging component 2 already have coils.

[0048] Then, in the wire arranging component 2, there is a conveyor belt for placing the coil fixtures. Several sets of wire arrangers 8 are respectively arranged on both sides of the coil fixtures. The so-called wire arranger 8 is a pneumatic or electric clamp, which also clamps from the root of the coil and straightens it outwards to form two winding groups. The coil fixtures are transported to the wire splitting component 3 through the conveyor belt for wire splitting processing.

[0049] The wire splitting component 3 includes a coil fixture, a wire splitting groove and a wire clamping device 10. Several coils are placed on the coil fixture. Two organized winding wires are respectively arranged on both sides of the coil. The wire clamping device 10 binds and arranges outwards from the root of the winding wire. After binding the longest winding wire, the longest winding wire is placed in the independent wire groove of the wire splitting groove by the movement of the clamping device until all the winding wires on the coil are respectively placed in the independent wire grooves of the wire splitting groove to complete wire splitting.

[0050] Furthermore, the transfer rack 9 has a wire arranging transfer rack 9 and a wire splitting transfer rack 9. The wire arranging transfer rack 9 transfers the coils coming out of the wire arranging component 2 to the wire splitting component 3 in a way of clamping the winding wires on both sides as a whole. The wire splitting transfer rack 9 separates and clamps the winding wires of the coils in the wire splitting state in the wire splitting component 3 through several clamping ends and transfers them to the casing component 4.

[0051] The casing component 4 includes a fixing rack for placing the plastic shell fixture 13. The coil in the wire splitting state is placed into the plastic shell on the plastic shell fixture 13 by the wire splitting transfer rack 9 for wire pressing and fixing.

[0052] Furthermore, it also includes a peeling component 5 arranged at the rear side of the material transfer direction of the casing component 4 or the wire splitting component 3. The peeling component 5 has a fixture turning frame 12 for placing the coil or the coil fixture. A laser 11 is arranged outside the fixture turning frame 12. The laser 11 moves towards the surface of the winding wire to burn and peel off the insulation layer.

[0053] The existing step method is to remove the external insulation layer material by laser or other methods after the wire winding is completed. However, this method has unstable effects because the wound winding wires will be wound and stacked, and the external treatment cannot affect the internally blocked parts, which will cause some insulation layers to still exist on its surface and affect its conductivity.

[0054] In this embodiment, the method is to perform skin removal treatment by laser before winding around the foot, and then wind around the foot. Only the position needs to be determined in advance, and then the skin is removed by laser burning, which has little impact on the conductivity after winding around the foot.

[0055] Specifically, first fix the coil in the wire-splitting state obtained from the previous processing flow, and keep all the winding wires of the coil in a straightened state outward in the wire-splitting state. At this time, most of each winding wire is in a parallel state after departing from the coil.

[0056] Then determine the burning area of each winding wire, determine a distance value from the outer end of the winding wire or a distance value from the straight line passing through the center of the coil and perpendicular to all winding wires. According to the distance value, adjust the relative position relationship between the laser device and the winding wire, align the burning area and move the laser to irradiate and remove the skin. After skin removal, a vision or testing device is used to detect the skin removal. If it meets the standard, the skin removal process is completed. If it does not meet the standard, secondary burning is judged according to the integrity of the winding wire or it is recycled as waste.

[0057] Furthermore, when determining the burning area, it is judged according to the state of the coil.

[0058] If the coil is outside the plastic case of the network filter, in the state where the winding wire is straightened outward, calculate the length from the root of the winding wire at the coil, add the estimated length of sinking into the plastic case when installed in the plastic case, and then determine a length range of 2 - 10 mm as the burning area.

[0059] When the coil is pressed into the plastic case of the network filter, in the state where the winding wire is straightened outward, determine a length range of 2 - 10 mm between the pins of the plastic case and the external pins as the burning area. In this embodiment, a length range of 5 mm is used as the determined burning area for burning. The area covered by the beam of the laser 11 falling on the winding wire has a length of 5 mm, and a single irradiation for a fixed time can complete the formation of the burning area with a length of 5 mm.

[0060] Furthermore, when the laser device moves the laser to irradiate the burning area, first rotate and burn in the circumferential direction of the winding wire when the laser device irradiates, and then after rotating and burning at least 60 degrees, move the laser device to the next winding wire for circumferential rotation and burning.

[0061] The laser beam of the laser device covers the length of the winding wire within the length range of the burning area, and the laser device rotates circumferentially around the winding wire by at least 60 degrees to complete the burning of a single winding wire. When the length of the laser beam of the laser device covering the winding wire is less than the length range of the burning area, first move the laser device along the length direction of the winding wire to burn and form a peeling area with a length within the length range of the burning area, and then rotate the laser device circumferentially around the winding wire, and move linearly in the opposite direction of the previous displacement by the same length and then rotate. Repeat the linear displacement and rotational displacement processes until the burning area reaches the set length range and angle range.

[0062] Further, the laser beam of the laser device covers the length of the winding wire within the length range of the burning area, and the laser device rotates circumferentially around the winding wire by at least 60 degrees to complete the burning of a single winding wire.

[0063] Based on the above-mentioned method of the laser coverage area length of 5 mm, the width of the irradiated covered area is described as a percentage of the side length of the cross-section of the winding wire. The width value of the single laser beam fixedly irradiated on the winding wire is close to 50% each time, and then the burning angle of rotation is 60 degrees. The unilateral rotation can increase the coverage area in the width direction to about 80%. If the fixed-angle irradiation is used as a fixed value, the laser device 11 is moved and irradiated by swinging 160 degrees to the left and right respectively, and the burning area of the winding wire with a length of 5 mm can completely cover the curved surface of this section of the winding wire, so as to achieve a better peeling effect.

[0064] It should also be noted that the laser device 11 includes two schemes of single-beam laser and multi-beam parallel laser beams. The interval of the multi-beam parallel laser beams corresponds to adjacent winding wires or the same number of winding wires at intervals, and can perform moving irradiation on multiple winding wires simultaneously each time, improving the peeling efficiency.

[0065] Further, the laser burning and peeling method in this embodiment is based on an automated laser peeling system. Refer to Figure 5 , the figure shows the structural features of the laser peeling system, including: The laser device 11 is fixed on the operation tabletop through a fixing frame; The fixture is used to place several coils or the plastic cases containing coils; and The fixture fixing table is arranged on the operation tabletop to fix the fixture and direct the fixture towards the emitting end face of the laser device 11 for burning.

[0066] It further includes a laser translation frame arranged on the operation tabletop. The fixing frame is arranged on the laser translation frame and reciprocates linearly along the laser translation frame. There is also a lifting frame between the fixing frame and the laser translation frame, and the fixing frame reciprocates vertically relative to the fixture through the lifting frame.

[0067] It further includes a fixture moving frame disposed on the operation platform, and the fixture fixing table reciprocates along the length direction of the fixture moving frame on the fixture moving frame; a fixture frame is rotatably connected to the fixture fixing table, and the fixture frame is controlled by a rotating motor disposed on the fixture fixing table to rotate relative to the wire harness direction of the laser 11.

[0068] Further, it further includes an inspection and packaging assembly 6 disposed at the end of the material transfer direction, and the inspection and packaging assembly 6 visually inspects the plastic shell containing the coil and then transfers it after shelling.

[0069] The present invention is not limited to the above optional embodiments, and anyone can obtain other various forms of products under the inspiration of the present invention. The above specific embodiments should not be construed as limiting the protection scope of the present invention, and the protection scope of the present invention should be defined by the claims, and the specification can be used to interpret the claims.
