Description

Technical Field

[0001] The present invention belongs to the technical field of wire dividing devices, and particularly relates to a method and system for casing and pressing wires of a network filter coil. 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 soldering, shielding, and encapsulation. The core usually uses a ferrite core. The coil can be wound in a single-layer or multi-layer manner. The insulating material is used to ensure electrical isolation between coils. The pins are made of copper or other conductive materials and are connected to the coils by soldering. To reduce electromagnetic interference, some network transformers are designed with a metal shield. The casing can be plastic or metal, which is used to protect the internal structure and provide mechanical support.

[0003] The manufacturing process of a network transformer includes core preparation, coil winding, pin soldering, insulation treatment, shielding and encapsulation, and testing and aging treatment. According to the design requirements, during production, primary and secondary coils need to be wound on the core. Currently, winding is usually done manually, and there are a small number of automated devices dedicated to winding network transformers. The wound coils are soldered to the pins to ensure the reliability of the connection and 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 wire harnesses, 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 inserting the coil into the case, the existing method is to manually align and insert the coil into the plastic case. This method of inserting into the case is not applicable to the automated process, and there is no device or method in the prior art to automatically place the coil and the separated winding wires into the plastic case. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a system and method for casing and pressing wires of a coil applicable to an automated device, which has higher stability and yield compared with the manual method.

[0006] The technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a system for housing and pressing the coils of a network filter. The coiled wires after wire separation are placed into the plastic housing of the network filter in a wire-separated state. The system includes a fixed position for holding the plastic housing, and a wire-separating transfer rack that moves relative to the fixed position and is used to lift the coils and the winding wires. The wire-separating transfer rack is provided with wire-separating clamps for individually clamping and limiting the winding wires on the same coil. The wire-separating transfer rack presses the coils into the plastic housing and maintains the wire-separated state of the winding wires of each coil entering the plastic housing.

[0007] It should be noted that the fixed position is a structural reference for placing the plastic housing, and is not limited to various forms of fixing structures. Generally, a special fixture is used. This structure needs to cooperate with subsequent processing technological processes. If re-transfer and movement are required, generally a general fixture is used for fixing, or a conveyor belt with a special setting position is used. That is, the plastic housing after the coils are pressed in will be conveyed by the conveyor belt to the next station for disposal, such as laser peeling or direct wire winding.

[0008] Among them, the wire-separating transfer rack is used to transfer the coiled wires that have been wire-separated in the previous processing process as a whole into the corresponding plastic housing at the fixed position, and maintain the wire-separated state of all the winding wires of the coil when the coil is pressed in. The so-called wire-separated state means that two bundles of multiple winding wires of the coil are in a state of being separated individually in the previous process, and maintain the state of individual separation for displacement, that is, it is realized through the wire-separating clamps for individually clamping and limiting the winding wires.

[0009] Combined with the first aspect, the present invention provides a first implementation manner of the first aspect. The wire-separating clamp includes a plurality of clamping arms, and a clamping groove for clamping the winding wires is formed between adjacent clamping arms.

[0010] Combined with the first implementation manner of the first aspect, the present invention provides a second implementation manner of the first aspect. The number of the clamping arms is an even number and they are grouped in pairs, and each group of clamping arms is controlled to open and close by an independent actuating component.

[0011] Combined with the first implementation manner of the first aspect, the present invention provides a third implementation manner of the first aspect. All the clamping arms are driven by the same actuating component and displace synchronously, and the clamping grooves between adjacent clamping arms open and close simultaneously.

[0012] Combined with several implementation manners of the first aspect, the present invention provides a fourth implementation manner of the first aspect. The wire-separating transfer rack includes a coil holder for fixing the coil in the middle, and wire-separating clamps symmetrically arranged on both sides of the coil holder.

[0013] Combined with the fourth implementation manner of the first aspect, the present invention provides a fifth implementation manner of the first aspect. The coil holder fixes the coil by magnetic attraction, and a push rod for pushing the coil away from the magnetic attraction point is provided on the wire-separating transfer rack.

[0014] Combined with several embodiments of the first aspect, the present invention provides a sixth embodiment of the first aspect. The fixing position is a plastic shell fixture, and the plastic shell fixture has a fixing position for placing a magnetic ring and a wire groove for restricting winding wires and maintaining a wire splitting state.

[0015] Combined with the sixth embodiment of the first aspect, the present invention provides a seventh embodiment of the first aspect, further including a wire inlet tooling arranged above the fixing position. The wire inlet tooling has a blanking gap corresponding to the lower plastic shell fixture, and the coil falls into the plastic shell of the plastic shell fixture from the blanking gap. An inlet wire guiding frame for guiding the winding wires into the wire groove is provided at the opening, and a plurality of wire inlet grooves corresponding to the wire grooves are provided on the inlet wire guiding frame.

[0016] Combined with the seventh embodiment of the first aspect, the present invention provides an eighth embodiment of the first aspect. The wire inlet tooling includes a shell inlet clamping table, and the shell inlet clamping table includes two relatively displaceable table frames, and a blanking gap is formed between the table frames. When the table frames are clamped, the plastic shell fixture is clamped and fixed between the table frames, and when the table frames are opened, the plastic shell fixture is released. It further includes a shell inlet slide rail. An inlet shell slide for supporting the plastic shell fixture is provided at the lower part of the shell inlet clamping table. The inlet shell slide is slidably matched with the shell inlet slide rail, and after the shell inlet clamping table releases the plastic shell fixture, the plastic shell fixture is driven by the inlet shell slide to be transferred along the shell inlet slide rail to the outside.

[0017] In a second aspect, the present invention provides a method for installing a coil in a shell and pressing the wire, using the above-mentioned network filter coil shell installation and wire pressing system, specifically as follows: First, the coil is transferred from the outside to above the plastic shell fixture by the wire splitting transfer frame while maintaining the wire splitting state of the winding wires, and is correspondingly placed on the plastic shell on the plastic shell fixture. When placing, the coil is placed in the plastic shell, the corresponding winding wires of the coil are respectively placed in independent wire grooves, and the coil and the winding wires in the plastic shell are pressed against the inner bottom of the plastic shell. Finally, the wire splitting transfer frame releases the coil and the winding wires simultaneously to complete the shell installation and wire pressing process.

[0018] The beneficial effects of the present invention are as follows: (1) Through the provided movable wire splitting transfer frame, the present invention can cooperate with the upper and lower technological processes, pick up the already wire-split coil from the position of the previous process for transfer, and directly install the coil through the wire splitting transfer frame. At the same time, the provided wire splitting fixture always fixes all the winding wires during the transfer and shell installation processes to keep them in a wire-split state, avoiding the displacement of the winding wires during the transfer and shell installation processes and affecting the subsequent wire winding process. (2)The automated transfer, casing insertion, and wire pressing equipment of the present invention cooperate to automate the entire process of casing insertion and wire pressing, improving efficiency and yield, reducing labor costs, and enhancing stability. (3)With the wire insertion tooling and the wire splitting transfer rack provided in the present invention, not only can a guiding effect be achieved, but also it is convenient for the winding wire to enter the corresponding wire grooves of the plastic shell fixture for fixation. At the same time, through the openable bench structure, the fixation and release of the plastic shell fixture are realized, facilitating the overall transfer of several plastic shells completed with casing insertion to the next process for disposal through the plastic shell fixture.

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 circumstances.

[0028] Embodiment 1: The present embodiment discloses a coil casing and wire crimping system for a network filter, wherein the coil is taken as the main processing object in the present embodiment, and only a single process in the network filter manufacturing process is involved. The coil is branched in the previous process flow, so that the coil has two winding wires in a symmetrical branched state on both sides. At this time, several coils need to be installed in the same plastic shell, and then the plastic shell is transferred to the next process flow for laser peeling or foot winding. The casing and wire crimping system in the present embodiment belongs to the intermediate link, and only a semi-finished product of the network filter is formed.

[0029] It should be noted that the coil treatment of the network filter is used for explanation in this embodiment. For those skilled in the art, it is not limited to the application scenario of the network filter. For example, the network transformer has the same coil shell installation process, which also falls within the scope covered by this embodiment.

[0030] Specifically, the coil shell crimping system in this embodiment includes a fixed table and a wire splitting transfer frame 9 movable relative to the fixed table, wherein a plastic shell with an opening facing upward is placed on the fixed table, and the wire splitting transfer frame 9 transfers the coil processed in the previous process flow into the plastic shell.

[0031] The wire splitting transfer frame 9 has an end portion for limiting the connection of the coil, and a wire splitting clamp 12 is provided on both sides of the end portion. The wire splitting transfer frame 9 lifts the coil by the end portion, clamps all the winding wires corresponding to the coil by the wire splitting clamp 12, and maintains the wire splitting state of the winding wires when the coil moves with the wire splitting transfer frame 9. After the coil is transferred to the fixed table by the wire splitting transfer frame 9, the coil and part of the winding wires are placed in the plastic shell at the same time, and the coil and the winding wires in the plastic shell are pressed together on the inner bottom of the plastic shell, wherein the winding wires in the plastic shell are pressed together as closely as possible to the inner wall of the plastic shell by the end portion of the coil connected by the wire splitting transfer frame 9, and the winding wires outside the plastic shell are kept in the wire splitting state through the wire grooves provided on the fixed table.

[0032] Specifically, as an implementation method, a columnar structure for limiting the connection of the coil is provided in the middle of the branch line transfer frame 9, and the wire is transmitted into the middle of the coil through the columnar structure to achieve socket connection. A push rod is provided on one side of the columnar structure, and the push rod pushes the coil to separate from the columnar structure and rest against the inner bottom of the plastic shell for release.

[0033] As an implementation method, a plurality of magnetic columns are provided in the middle of the branch line transfer frame 9, and the coil is attracted by the magnetic attraction of the ends of the magnetic columns, and a push rod is provided on the branch line transfer frame 9, and the push rod is movable. When the magnetic column brings the coil into the plastic shell and has a certain distance from the bottom of the plastic shell, the push rod holds the coil and moves it downward, causing the coil to separate from the magnetic column and fall on the inner bottom of the plastic shell. The thrust of the push rod can be maintained so that the coil can fit into the bottom of the plastic shell and remain stable, thereby completing the effects of transfer, shell loading and wire pressing.

[0034] Among them, the area of ​​the push rod end is larger than the area of ​​the coil, and the push rod end can cover most of the bottom of the plastic shell. When the push rod pushes the coil to the bottom of the plastic shell, the winding wires around the coil entering the plastic shell are all supported by the push rod end and fit against the inner wall of the plastic shell and continue to move downward until the coil and all the winding wires can be completely fit in the inner bottom of the plastic shell. Then, the push rod is lifted to complete the shell installation and wire pressing process.

[0035] It should be noted that the entire device is continuously controlled by a set automation program. When pressing the wire, the winding wire outside the plastic shell is driven by the wire splitter clamp 12 into the corresponding wire slot to achieve position limiting. The wire slot itself can provide a separation effect for adjacent winding wires, and can also limit each winding wire from leaving the wire slot through a certain binding force. When the winding wire enters the wire slot 6, the end of the magnetic column only brings the coil into the plastic shell, and the push rod does not push it. When the winding wire is released by the wire splitter clamp 12, the push rod pushes the coil and the winding wire in the plastic shell downward. Due to the loss of the restriction of the wire splitter clamp 12, each winding wire produces a limit displacement in the wire slot, that is, it moves a certain distance toward one side of the plastic shell. In order to avoid the situation where the wire is broken due to the tension of the winding wire when the push rod is pressing the wire, the above-mentioned linkage control mechanism requires the wire splitter clamp 12 to release all the winding wires before pressing the wire. In some embodiments, the winding wire is not limited to being confined in the corresponding wire slot. The winding wire can be released by adjusting the clamping force of the wire splitter clamp 12. At this time, the resistance received by the pressed winding wire is less than the force of breaking the wire, and the effect of directional release of the pressed wire can also be achieved.

[0036] Furthermore, the wire splitting clamp 12 is arranged on both sides of the wire splitting transfer frame 9 for fixing the ends of the coil. The wire splitting clamp 12 has a plurality of clamping arms, and the clamping arms have two control modes. One is that two clamping arms form a clamping structure, and a single clamping structure is driven by an independently arranged motor mechanism to control opening and closing. Each clamping structure forms a wire slot for binding and releasing the winding wire of the matching coil. This control mode is more precise and can accurately clamp each winding wire.

[0037] The other is that all the clamping arms are mounted on the same group of fixed shafts, the gaps between adjacent clamping arms are the wire grooves, and all the clamping arms are opened and closed by being pushed and controlled by the same group of motor mechanisms. In order to achieve simultaneous release and clamping of the clamping arms, especially to keep the gaps between the clamping arms the same after release, elastic parts with the same elastic force are provided between adjacent clamping arms, and a clamping force is applied on both sides of all the clamping arms in a pneumatic or electric manner. When clamping, all the clamping arms overcome the elastic parts to clamp, and when releasing, all the clamping arms expand by maintaining the same gap through the same elastic parts.

[0038] Reference Figure 7, the figure shows the way that the above-mentioned multiple sets of clamping arms are driven by a unified power mechanism to open and close. It can be seen that on the wire splitting transfer rack 9 in the figure, there are several sets of symmetrically arranged wire splitting clamps 12. Each wire splitting clamp 12 has four clamping arms, forming three wire grooves. Clamping is achieved by the displacement of the larger clamping arms on both sides towards the middle. Before wire clamping, the openings of all wire grooves are expanded first, and then the wire splitting clamp 12 is moved downward so that the winding wires of the coil in the wire splitting state can enter the corresponding wire grooves. When releasing, the winding wires in the wire grooves of the fixed table can also be released by releasing the clamping arms and restricted in the wire grooves of the fixed table.

[0039] Further, referring to Figures 5 - 7 , the coil casing and wire pressing system in this embodiment includes a fixed transfer carriage 10, and two transfer racks are slidably fitted on the transfer carriage 10, namely the whole wire transfer rack 8 and the wire splitting transfer rack 9.

[0040] Referring to Figure 6 , the middle part of the whole wire transfer rack 8 also has an end for limiting and connecting the coil, and several whole wire clamps 11 are symmetrically arranged on both sides of the end. Among them, the whole wire clamp 11 is a structure for clamping and transferring the winding wire harnesses on both sides of the non-wire-split coil as a whole. Through the whole wire transfer rack 8, the coil can be moved in the previous wire splitting process flow in this embodiment. By being co-mounted with the wire splitting transfer rack 9 for casing and wire pressing in this embodiment, the integrity is improved, the cost is reduced, and it is convenient for the continuous operation of the entire production line.

[0041] Further, referring to Figures 1 - 4 , the figure shows the structure arranged on the fixed table for cooperating with the wire splitting transfer rack 9 for coil casing and wire pressing, which is specifically as follows: The whole casing and wire pressing system further includes an incoming wire tooling 1, an incoming casing slide rail 3 and an incoming casing slide table that displaces along the incoming casing slide rail 3. Among them, the fixed table is a plastic shell fixture 7 arranged on the incoming casing slide table, and several plastic shells with openings facing upwards are placed on the plastic shell fixture 7. The incoming wire tooling 1 includes a set of incoming casing clamping tables 2 arranged on the incoming casing slide table. The incoming casing clamping table 2 includes two table frames, and the table frames are displaced relative to the incoming casing slide table in a pneumatic or electric manner, forming a blanking gap between the two table frames. Several coils lifted by the wire splitting transfer rack 9 will fall into the plastic shells in the plastic shell fixture 7 through the blanking gap.

[0042] There is a groove for placing the plastic shell in the middle of the plastic shell fixture 7, and wire grooves are symmetrically arranged on both sides of the groove. The wire groove in this embodiment is a spring structure, which is fixed and has several gaps. The winding wire can enter the independent gaps and achieve a certain degree of clamping and limiting through the converging effect of the spring structure.

[0043] Referring to Figure 4, fixture clamps 4 for fixing the fixture are provided on two benches, and wire inlet guiding frames 5 for guiding the winding wires to separately enter the wire grooves 6 are provided on both sides of the fixture clamp 4. For several plastic cases on the same plastic case fixture 7, several groups of wire inlet guiding frames 5 are correspondingly provided.

[0044] Each wire inlet guiding frame 5 has several inwardly inclined wire grooves 6. Each wire groove 6 has a wire inlet gap penetrating up and down. And in line with the characteristics of the coil expanding and dispersing to the external winding wires, the wire groove 6 has a structural feature of being tight inside and loose outside.

[0045] It should be noted that during the case loading process, the wire separating transfer frame 9 drives the coil downward from the upper part of the wire inlet tooling 1 and finally lands on the plastic case fixture 7. Among them, the coil falls into the plastic case from the middle blanking gap, and the blanking gap is communicated with each wire groove 6. Then the wire separating clamp 12 outside the bench clamps each winding wire and enters from the upper opening of the wire groove 6, and finally falls into the wire groove inside the lower side of the wire groove 6 to achieve positioning.

[0046] For the way that the plastic case fixture 7 detaches from the wire inlet tooling 1 and slides through the case loading slide rail 3, this embodiment provides two implementation manners.

[0047] As an implementation manner, after the wire inlet tooling 1 guides all the coils to fall into the plastic case, it opens the bench so that the width of the middle blanking gap exceeds the width of the plastic case fixture 7, and then an external device lifts the entire plastic case fixture 7 upward from the upper part of the blanking gap, so as to complete the transfer effect.

[0048] As an implementation manner, when the bench is clamped, the plastic case fixture 7 is clamped and fixed between the benches, and when the bench is opened, the plastic case fixture 7 is released. After the case loading clamping table 2 releases the plastic case fixture 7, the case loading slide table drives the plastic case fixture 7 to transfer to the outside along the case loading slide rail 3.

[0049] The present invention is not limited to the above optional implementation manners, and anyone can obtain other various forms of products under the inspiration of the present invention. The above specific implementation manners should not be construed as limiting the protection scope of the present invention. The protection scope of the present invention should be defined by the claims, and the description can be used to explain the claims.
