Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of line splitting equipment, and particularly relates to a network filter coil casing and line pressing method and system. BACKGROUND

[0002] Network transformers, also known as network isolation transformers or pulse transformers, are electronic components used for data transmission and signal isolation. They have wide applications in network communication, industrial control, power systems, etc. Network transformers include magnetic core material, coil structure, insulation material, pin and welding, shielding, and packaging. The magnetic core usually uses ferrite magnetic core, the coil can be wound in single layer or multi-layer, the insulation material is used to ensure the electrical isolation between coils, the pin is made of copper or other conductive materials and connected with the coil by welding. In order to reduce electromagnetic interference, some network transformers are designed with metal shielding. The shell can be plastic or metal, which protects the internal structure and provides mechanical support.

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

[0004] Before winding, the winding lines of the winding (magnetic ring structure after winding of the magnetic core) need to be combed, i.e. the corresponding number of winding lines are straightened to form two bundles of lines on both sides, and then placed in the rubber shell of the network transformer after manual separation for pinning process. In this process, the existing method is to manually align the coil and place it in the rubber shell during the coil insertion process. This insertion method is not suitable for automated processes, and there is no device or method in the prior art that can automatically place the coil and separated winding lines in the rubber shell. SUMMARY

[0005] In order to solve the problems existing in the prior art, the application provides a system and method suitable for automatic equipment for coil insertion and line pressing, which has higher stability and yield compared with manual methods.

[0006] The technical solution adopted by the application is:

[0007] In a first aspect, the present application provides a network filter coil housing and wire pressing system, which places the divided coil in the divided state into the rubber shell of the network filter, comprising a fixed position for bearing the rubber shell, and a divided transfer frame for lifting the coil and the winding wire, which moves relative to the fixed position, and the divided transfer frame has a wire dividing clamp for clamping and limiting the winding wire on the same coil, and the divided transfer frame presses the coil into the rubber shell and maintains the divided state of the winding wire of each coil entering the rubber shell.

[0008] It is worth noting that the fixed position is a structure for placing the rubber shell, which is not limited to various forms of fixed structures, and generally uses a special jig. The structure needs to cooperate with the subsequent processing process. If it needs to be moved again, a general jig is generally used for fixation, or a conveyor belt with a special setting position is used, that is, the rubber shell after the coil is pressed in is conveyed to the next station for processing, such as laser peeling or direct winding.

[0009] The divided transfer frame is used to transfer the coil with divided wires from the previous processing process to the corresponding rubber shell on the fixed position, and to maintain the divided state of all winding wires of the coil when the coil is pressed in. The so-called divided state refers to the state of two bundles of winding wires of the coil being separated single-rooted in the previous process, and being displaced in a single-rooted separated state, that is, realized by the wire dividing clamp for clamping and limiting the winding wire.

[0010] In combination with the first aspect, the present application provides a first embodiment of the first aspect, wherein the wire dividing clamp comprises a plurality of clamping arms, and a wire clamping groove for clamping the winding wire is formed between adjacent clamping arms.

[0015] In combination with the several implementation manners of the first aspect, the application provides a sixth implementation manner of the first aspect, wherein the fixing position is a glue shell jig, the glue shell jig is provided with a fixing position for placing the magnetic ring, and a wire slot for limiting the winding wire and maintaining the separated wire state.

[0016] In combination with the sixth implementation manner of the first aspect, the application provides a seventh implementation manner of the first aspect, further comprising a wire feeding tool arranged on the upper part of the fixing position, the wire feeding tool is provided with a material falling gap corresponding to the lower glue shell jig, and the coil falls into the glue shell of the glue shell jig from the material falling gap.

[0017] A wire feeding guide frame for guiding the winding wire to enter the wire slot is arranged at the opening, and the wire feeding guide frame is provided with a plurality of wire feeding slots corresponding to the wire slots.

[0018] In combination with the seventh implementation manner of the first aspect, the application provides an eighth implementation manner of the first aspect, wherein the wire feeding tool comprises an entering shell clamp table, the entering shell clamp table comprises two oppositely displaced table frames, and a material falling gap is formed between the table frames.

[0019] When the table frames are clamped, the glue shell jig is clamped and fixed between the table frames, and when the table frames are opened, the glue shell jig is released.

[0020] Further comprising an entering shell sliding rail, the lower part of the entering shell clamp table is provided with an entering shell sliding table for supporting the glue shell jig, the entering shell sliding table and the entering shell sliding rail are slidingly matched, and after the entering shell clamp table releases the glue shell jig, the entering shell sliding table drives the glue shell jig to shift to the outside along the entering shell sliding rail.

[0021] In the second aspect, the application provides a coil shell loading and wire pressing method, which adopts the network filter coil shell loading and wire pressing system, and the specific process is as follows.

[0022] Firstly, the coil is transferred from the outside to the upper part of the glue shell jig while maintaining the winding wire separated state through the separated wire transfer frame, and the coil is placed in the glue shell corresponding to the glue shell jig;

[0023] When the coil is placed in the glue shell, the winding wire corresponding to the coil is placed in the independent wire slot, and the coil and the winding wire in the glue shell are pressed and combined at the inner bottom of the glue shell.

[0024] Finally, the separated wire transfer frame releases the coil and the winding wire at the same time to complete the shell loading and wire pressing process.

[0025] The application has the following beneficial effects:

[0026] (1) The present invention, through the movable wire transfer frame, can cooperate with the upper and lower process flow, take the coil that has been wired from the position of the previous process for transfer, and directly put the coil into the shell through the wire transfer frame.

[0028] (3) The present invention, through the combination of the wire entry tooling and the wire transfer frame, can not only play a guiding role, but also facilitate the winding wire to enter the corresponding wire slot of the plastic housing fixture for fixing.

[0044] Embodiment 1:

[0045] The present embodiment discloses a coil housing and pressing system of a network filter, wherein the coil is the main object of treatment in the present embodiment, and only a single process in the network filter manufacturing process is involved. The coil is divided into two symmetrical strands of winding wires in the previous process, and then a plurality of coils are loaded into the same glue shell, and the glue shell is transferred to the next process for laser peeling or winding. The coil housing and pressing system in the present embodiment is an intermediate link, and only a semi-finished product of the network filter is formed.

[0046] It should be noted that the coil treatment of the network filter is described in the present embodiment, and for those skilled in the art, it is not limited to one application scenario of the network filter, for example, the network transformer has the same coil housing process, which also belongs to the scope covered by the present embodiment.

[0047] Specifically, the coil housing and pressing system in the present embodiment includes a fixed table and a dividing and transferring frame 9 movable relative to the fixed table, wherein the fixed table is provided with a glue shell with an opening upward, and the coil treated in the previous process is transferred to the glue shell by the dividing and transferring frame 9.

[0048] The dividing and transferring frame 9 has an end portion limiting the connection of the coil, and a dividing clamp 12 is arranged on both sides of the end portion. The dividing and transferring frame 9 lifts the coil by the end portion, holds all the winding wires corresponding to the coil by the dividing clamp 12, and maintains the divided state of the winding wires when the coil moves with the dividing and transferring frame 9. After the coil is transferred to the fixed table by the dividing and transferring frame 9, the coil and part of the winding wires are placed in the glue shell, and the coil and the winding wires in the glue shell are pressed and combined at the inner bottom of the glue shell. The winding wires in the glue shell are pressed and combined as much as possible on the inner wall of the glue shell through the end portion of the coil connected by the dividing and transferring frame 9, and the winding wires outside the glue shell maintain the divided state through the wire slot arranged on the fixed table.

[0049] Specifically, as an embodiment, the dividing and transferring frame 9 is provided with a columnar structure for limiting the connection coil, the middle part of the coil is connected through the columnar structure, a push rod is arranged on one side of the columnar structure, and the coil is separated from the columnar structure through the push rod and is released by abutting against the inner bottom of the rubber shell.

[0050] As an embodiment, the dividing and transferring frame 9 is provided with a plurality of magnetic columns, the coil is attracted by the end part of the magnetic column, and a push rod is arranged on the dividing and transferring frame 9, the push rod is movable, when the coil is brought into the rubber shell by the magnetic column and has a certain distance from the inner bottom of the rubber shell, the coil is abutted and moved downward by the push rod, so that the coil is separated from the magnetic column and falls on the inner bottom of the rubber shell, the push rod can keep the pushing force, so that the coil can be attached to the inner bottom of the rubber shell and kept stable, thereby completing the transferring, shell mounting and wire pressing effect.

[0051] The end part of the push rod has an area greater than that of the coil, and the end part of the push rod can cover most of the inner bottom of the rubber shell, when the coil is pushed to the inner bottom of the rubber shell by the push rod, the winding wire around the coil entering the rubber shell is abutted and attached to the inner wall of the rubber shell by the end part of the push rod in a way of continuously moving downward, until the coil and all the winding wires can be completely attached to the inner bottom of the rubber shell, the shell mounting and wire pressing process is completed by lifting the push rod.

[0052] It should be noted that the entire device is continuously controlled by a set of automatic programs, when the wire is pressed, the winding wire outside the rubber shell is limited by being brought into the corresponding wire slot by the dividing clamp 12. The wire slot itself can provide a separation effect for the adjacent winding wires, and can also limit each winding wire from leaving the wire slot by a certain binding force. When the winding wire enters the wire slot 6, the end part of the magnetic column only brings the coil into the rubber shell, and the push rod is not pushed, when the winding wire is released by the dividing clamp 12, the coil and the winding wire in the rubber shell are pushed downward by the push rod. Since the limiting displacement of each winding wire in the wire slot is generated due to the loss of the dividing clamp 12, i.e. moving a certain distance towards the rubber shell side. The above linkage control mechanism needs to release all the winding wires by the dividing clamp 12 before pressing the wire, in order to avoid the situation that the winding wire is broken due to being tightened when the push rod presses the wire. In some embodiments, the winding wire is not limited to being limited in the corresponding wire slot, but can be released by adjusting the clamping force of the dividing clamp 12, at this time, the resistance received by the winding wire during pressing is less than the breaking force, and the effect of directional release and pressing of the winding wire can also be achieved.

[0053] Further, the wire separation clamp 12 is arranged on the wire separation transfer frame 9 for fixing the two sides of the end of the coil, and the wire separation clamp 12 has a plurality of clamp arms, and the clamp arms have two control modes, one is that two clamp arms form a wire clamping structure, and a single set of wire clamping structures is driven and controlled to open and close by a separately arranged driving mechanism, and each wire clamping structure forms a wire slot for matching the binding and release of the winding wire of the coil. This control mode is more accurate and can accurately clamp each winding wire.

[0054] The other is that all the clamp arms are sleeved on the same set of fixed shafts, and the gap between adjacent clamp arms is a wire slot, and all the clamp arms are driven and controlled to open and close by the same set of driving mechanisms. In order to realize the simultaneous release and clamping of the clamp arms, especially to keep the same gap between the adjacent clamp arms after release, elastic members with the same elastic force are arranged between the adjacent clamp arms, and a clamping force is applied to the two sides of all the clamp arms in the form of pneumatic or electric, so that all the clamp arms are clamped by overcoming the elastic members when clamping, and all the clamp arms are expanded by the same elastic members to keep the same gap when releasing.

[0055] Referring to Figure 7 , the figure shows the above-mentioned mode of opening and closing of multiple sets of clamp arms driven by a unified driving mechanism. As can be seen from the figure, the wire separation transfer frame 9 is provided with a plurality of sets of symmetrically arranged wire separation clamps 12, each wire separation clamp 12 has four clamp arms, forming three wire slots, and the clamp arms are displaced from both sides to the middle to achieve clamping. Before clamping the wire, the openings of all the wire slots are expanded, and then the wire separation clamp 12 is moved downward so that the winding wire of the coil in the wire separation state can enter the corresponding wire slot. When releasing, the winding wire in the wire slot of the fixed table can be released and limited in the wire slot of the fixed table by releasing the clamp arms.

[0056] Further, referring to Figures 5-7 , the coil shell assembling and wire pressing system in the embodiment includes a fixedly arranged transfer slide 10, and the transfer slide 10 is slidably connected with two transfer frames, i.e. a whole wire transfer frame 8 and a wire separation transfer frame 9.

[0057] Referring to Figure 6 , the middle part of the whole wire transfer frame 8 also has a limiting connection for the end of the coil, and a plurality of whole wire clamps 11 are symmetrically arranged on both sides of the end. The whole wire clamp 11 is a structure for clamping and transferring the winding wire bundle on both sides of the coil before wire separation. The whole wire transfer frame 8 can move the coil in the last wire separation process in the embodiment, and the whole wire transfer frame 8 is arranged in the same frame as the wire separation transfer frame 9 for shell assembling and wire pressing in the embodiment to improve the integrity and reduce the cost, thereby facilitating the continuous operation of the whole assembly line.

[0058] Further, referring to Figures 1-4 , the figure shows the structure arranged on the fixed table for matching the wire separation transfer frame 9 to assemble the coil shell and press the wire, and the specific structure is as follows:

[0059] The whole shell filling and winding system further comprises a winding tool 1, a shell sliding rail 3 and a shell sliding table which moves along the shell sliding rail 3, wherein the fixed table is a shell jig 7 arranged on the shell sliding table, and a plurality of shell jigs with openings upward are arranged on the shell jig 7. The winding tool 1 comprises a set of shell clamping tables 2 arranged on the shell sliding table, the shell clamping tables 2 comprise two table frames which are relatively displaced relative to the shell sliding table by a pneumatic or electric mode, and a material falling gap is formed between the two table frames, and a plurality of coils lifted by the branch line transfer frame 9 will fall into the shell jigs 7 through the material falling gap.

[0060] The shell jig 7 has a groove for placing the shell in the middle, and wire grooves are symmetrically arranged on both sides of the groove. The wire groove in the embodiment is a spring structure, which is fixed and has a plurality of gaps, and the winding wire can enter the independent gaps and achieve a certain degree of clamping and limiting through the convergence effect of the spring structure.

[0061] Referring to Figure 4 A jig clamp 4 for fixing the jig is arranged on the two table frames, and a winding guide frame 5 for guiding the winding wire to separate and enter the wire groove 6 is arranged on both sides of the jig clamp 4, and a plurality of sets of winding guide frames 5 are arranged corresponding to a plurality of shell jigs 7 on the same shell jig 7.

[0062] Each winding guide frame 5 has a plurality of inwardly inclined winding grooves 6, each winding groove 6 has a downwardly extending winding gap, and the winding groove 6 has the structural feature of being tight inside and loose outside in combination with the characteristics of the coil to the external winding wire expansion and dispersion.

[0063] It should be noted that during the shell filling process, the coil is driven downward from the upper part of the winding tool 1 by the branch line transfer frame 9 and finally falls on the shell jig 7, wherein the coil falls into the shell from the middle material falling gap, and the material falling gap is in communication with each winding groove 6, so that the branch line clamp 12 outside the table frame clamps each winding wire to enter from the upper opening of the winding groove 6 and finally falls into the wire groove on the lower side of the winding groove 6 to realize the limiting.

[0064] Regarding the shell jig 7 which is separated from the winding tool 1 and slides through the shell sliding rail 3, the embodiment provides two implementation modes.

[0065] As one implementation mode, after guiding all the coils to fall into the shell, the winding tool 1 opens the table frame so that the width of the middle material falling gap exceeds the width of the shell jig 7, and then the whole shell jig 7 is lifted upward from the upper part of the material falling gap by an external device, thereby achieving the transfer effect.

[0066] As an embodiment, the glue shell jig 7 is clamped and fixed between the racks when the racks are clamped, and the glue shell jig 7 is released when the racks are opened. After the glue shell jig 7 is released by the shell entering clamp table 2, the glue shell jig 7 is driven by the shell entering sliding table to shift to the outside along the shell entering sliding rail 3.

[0067] The present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application. The above-mentioned specific embodiments should not be understood as limiting the protection scope of the present application, and the protection scope of the present application should be defined by the claims, and the specification can be used to explain the claims.
