Description

Line pressing mechanism of network filter

Technical Field

The application relates to the technical field of network filter production, in particular to a network filter wire pressing mechanism.

Background

The network filter mainly has two functions, namely, the transmission data is that differential signals sent by the PHY are filtered by using a coil coupling of differential mode coupling to strengthen the signals, and the signals are coupled to the other ends of connecting network wires with different levels through the conversion of electromagnetic fields; and secondly, different levels among different network devices connected by the network cable are isolated so as to prevent the devices from being damaged by different voltages transmitted by the network cable. The structure of the network filter comprises a plurality of coils placed in the rubber shell, the free ends of the conductive wires in each coil are wound on the pins of the filter, in the current filter production process, in order to avoid the defect that the filter is poor due to the fact that one section of the conductive wires between the coils and the pins is too tight, manual wire pressing is needed to enable the conductive wires to be tightly attached to the inner wall of the rubber shell, the number of the coils in the filter is large, the production efficiency of the filter is low, and the yield is difficult to improve.

In the prior art, a tool for pressing wires is combined with a jig for loading a plurality of network filter semi-finished products, for example, an invention patent with application number 2023109739408. The structure disclosed by the patent can always line all network filter semi-finished products on the jig on the whole production assembly line. However, this wire pressing mode needs to improve conventional jig, results in forming the suppression effect to network filter semi-manufactured goods all the time on the tool, and network filter all single row is placed on current tool, in order to make things convenient for follow-up processing flow to carry out whole row to transfer with a plurality of network filter semi-manufactured goods on the tool, if this kind of fixed wire pressing mechanism then can not directly release the network filter on the tool, but need first manual work or automatic equipment take off the instrument of line pressing just can operate it, then increase process and corresponding equipment relatively, need transport simultaneously and to the arrangement of a plurality of line pressing instrument. Meanwhile, the conventional manufacturing process finds that the wire pressing flow is single-time application molding, and the wire rod does not have good internal stress, so that the wire rod can be kept stable after being pressed and deformed, and long-time pressing is not needed. And the pressing force of the pressing process realized by adopting the clamping or magnetic adsorption structure cannot be accurately regulated, if a longer pressing tool is adopted, relative errors are generated due to the self assembly precision, so that the lower pressures of wires in different network filters on the same jig are different, the redundant length formed on the network filters cannot meet winding requirements, and the yield in the winding process is reduced.

Disclosure of Invention

In order to solve the problem that the production efficiency is low caused by manual wire pressing of the network filter in the prior art, the application provides a wire pressing process and a wire pressing mechanism of the network filter, and meanwhile, the problem that the wire pressing effect of the conventional normal wire pressing structure combined with a jig is poor is solved.

In order to achieve the above purpose, the technical scheme adopted in the application is as follows:

a network filter wire pressing mechanism, comprising: the wire pressing unit is used for applying pressure to the wire in the direction close to the inner wall of the rubber shell of the network filter through the wire pressing part which can be elastically deformed after being pressed; the driving unit drives the line pressing unit to reciprocate linearly; and the fixed tooling is fixedly provided with the driving unit and slidably provided with the line pressing unit.

It should be noted that the problem solved by the wire pressing structure in the winding process of the network filter is briefly described in the winding process of the whole network filter, namely: in the early winding stage in the production process of the network filter, the coil before winding is placed in a rubber shell of the network filter, and the rubber shell is only a part of the whole shell structure of the network filter, so that the top of the rubber shell is open for winding conveniently. The coil is formed by winding a conductive wire on the annular magnet, two ends of the conductive wire are far away from the annular magnet and extend out of the rubber shell, and a part of the conductive wire outside the annular magnet has a certain length and remains a margin.

At this time, the conductive wires on different coils and the conductive wires with different colors are placed in disorder, and all the conductive wires need to be wound on the winding feet at the top of the rubber shell after being straightened. Before winding, the well-arranged conductive wires outside the rubber shell are equidistantly arranged on two sides, the conductive wires are in a straightened state, and the wires in the rubber shell are completely pulled out. The direct winding in the state can lead to the fact that the straightened wire rod is subjected to outward tension, and if the wire rod is not provided with certain pullout length redundancy, the situation that the wire rod in the rubber shell is broken easily occurs.

In the existing winding process, a worker needs to press the coil with a flat glue rod to enable the coil to be in contact with the bottom surface of the glue shell and keep fixed after wire arrangement, then the top of the glue rod needs to press the conductive wire to the inner wall of the glue shell, then forceps are used for clamping the tail end of the conductive wire, the length of the conductive wire is adjusted through the glue rod, the conductive wires outside the coil and inside the glue shell are enabled to be close to the inner wall of the glue shell, and therefore a U-shaped bent wire is formed on two sides of each coil in the glue shell, and then winding is conducted.

The U-shaped bending part is called a buffer arc in the field, and the effect of the buffer arc is to avoid the influence of the wire connection over-tightening on the winding process. Specifically, in the manual operation, the glue stick is controlled to slide along the surface of the conductive wire to be tightly attached to the inner wall of the glue shell, meanwhile, the pressure applied by the glue stick to the conductive wire is controlled to form a buffer arc, and the process of setting the buffer arc is a main difficulty in realizing the wire pressing flow by using automatic production equipment, so that the network filter is difficult to improve the production efficiency by using a full-automatic production line.

The conductive wire is pressed with the line ball portion that can elastic deformation to this scheme, and drive unit makes line ball portion follow specific direction motion, makes to put neat conductive wire in advance and press close to the rubber shell inner wall. The deformation of the wire pressing part can limit the pressure applied by the wire pressing part to the conductive wire within a certain range, so that the damage to the paint on the surface of the conductive wire is avoided, and the operation of manually controlling the pressure in manual wire pressing is replaced; on the other hand, deformation generated by continuous movement after the wire pressing part is contacted with the conductive wire can form a buffer arc on the premise of ensuring that the wire pressing cloth is contacted with the conductive wire, so that the operation of forming the buffer arc by moving a rubber rod in manual wire pressing is replaced.

Further, the line pressing part is in a triangular prism shape, and the position closest to the conducting line along the moving direction is an edge. The triangular prism-shaped line pressing part is pressed to start deformation after being contacted with the conductive line, and as the initial contact part is one edge of the line pressing part, the contact area between the line pressing part and the conductive line is obviously increased during deformation, and the conductive line is more favorable for being fixed on the surface of the rubber shell according to production standards.

Further, the moving direction of the wire pressing unit and the surface of the wire pressing part form an acute angle with the horizontal surface of the coil. In the scheme, the arrangement direction and the movement direction of the wire pressing unit are inclined relative to the coil, so that the bottom surface of the wire pressing unit is gradually close to the surface of the coil when the wire pressing unit is gradually close to the conductive wire and presses the conductive wire, and the coil can be pressed simultaneously, so that the coil is kept in a fixed state relative to the rubber shell.

Further, the line pressing unit comprises an installation panel, and one end of the installation panel is embedded into the line pressing part and is fixedly connected with the line pressing part.

Furthermore, a plurality of mounting teeth which are distributed at intervals are arranged at the matching position of the mounting panel and the wire pressing part in parallel, and the wire pressing part corresponds to the mounting teeth one by one.

Further, the fixed frock includes the base, and with the mount pad of being connected can be dismantled to the base, the mount pad surface is equipped with the slide rail and passes through slide rail and mount pad sliding fit's slide, slide surface and mounting panel and drive unit's power take off end fixed connection.

Further, the mounting seat is matched with the base through screws, and waist-shaped grooves are formed in the positions, matched with the screws, of the mounting seat.

Furthermore, the line pressing part adopts silica gel or silicone rubber with the hardness of 50-70 degrees.

The beneficial effects of this application are: the utility model provides a but elastic deformation's line ball portion presses the part of fixed conductor line in the rubber shell when automatic production equipment twines the wave filter conductor on around the foot, keeps the stability of conductor line, and the deformation of line ball portion when pressing can be in a certain limit with the pressure restriction that line ball portion applyed the conductor line on the one hand, avoids causing the damage to the lacquer coating on conductor line surface, and on the other hand line ball portion and conductor line contact back continue the deformation that the motion produced can form the buffer arc under the prerequisite of guaranteeing line ball cloth and conductor line contact.

Meanwhile, the wire pressing device is different from the existing wire pressing mode of always pressing the wire pressing tool on the jig, has better yield, and meanwhile, only needs to additionally add an automatic device in the process to press the wire, so that the degree of freedom of the network filter on the jig is not limited, and the network filter on the single jig can be conveniently and outwards transferred in the subsequent process.

Example 1:

referring to fig. 1 and 2, the present embodiment provides a wire pressing mechanism for a network filter, which is arranged on two sides of a wire winding and water conveying belt of the network filter, and is used for pressing wires stretched between coils in a plurality of network filters and inner walls of a rubber shell from two sides together or sequentially in a symmetrical manner, so that the wires are pressed and attached to the inner walls of the rubber shell to form a U-shaped buffer arc.

Specifically, the mechanism comprises a wire pressing unit 1, wherein a wire pressing part 102 which can be elastically deformed after being pressed is used for applying pressure to a conductive wire 6 in a direction close to the inner wall of a rubber shell 5 of a network filter; a driving unit 2 for driving the line pressing unit 1 to reciprocate linearly; and the fixture 3 is fixedly provided with the driving unit 2 and is slidably provided with the line pressing unit 1.

The network filter in this embodiment is a semi-finished product, that is, a rectangular glue shell 5 with an opening at one side is provided, a plurality of coils are placed along a central line in the glue shell 5, at least two conductive wires 6 on each coil extend outwards, the coils are placed on a jig after manual wire arrangement, an external transmission belt transmits the jig in an oriented manner, and at the moment, the opening of the glue shell 5 is placed upwards.

The working principle is as follows:

the wire pressing mechanism in this embodiment is used in a winding process in the early stage of the production of the network filter, the wire pressing mechanism is used for fixing the conductive wire 6 while winding, the wire pressing part 102 in the wire pressing unit 1 is a part directly contacted with the conductive wire 6, the driving unit 2 drives the wire pressing unit 1 to do linear motion, so that the wire pressing part 102 is used for pressing the conductive wire 6 against the inner wall of the rubber shell 5 of the filter and keeps fixed, and the fixing work is used for fixing the driving unit 2 at a proper position and enabling the wire pressing unit 1 to move within a fixed range.

Before working, the coil 4 is placed in the rubber shell 5, the coil 4 is formed by winding a conductive wire 6 on a ring-shaped magnet, two ends of the conductive wire 6 extend outside the ring-shaped magnet to form a free section to be fixed, and for convenience of understanding, the conductive wire 6 is actually a free section of the conductive wire 6 outside the coil 4 in the working process of describing the wire pressing mechanism. The rubber housing 5 is a part of the network filter housing, and the top of the rubber housing is open. Before the winding process goes on, need put wire 6 neatly, because the line ball mechanism in this application is part in the full-automatic production line, in order to guarantee that line ball portion 102 presses wire 6, wire 6 is according to the direction rectilinear movement that is close to the inner wall of gluey shell 5 and take place not squinting, and wire 6 is in the outer tip of gluey shell 5 and need use the fixed knot who suits to fix for wire 6 is in coil 4 outside and fixed knot construct between partial length suitable in order to keep certain rate of tension and have the surplus that can supply the line ball to adjust. When the wire pressing mechanism works, the driving unit 2 drives the wire pressing unit 1 to move unidirectionally along a linear track, the wire pressing part 102 gradually approaches the conductive wire 6 until the wire pressing part contacts the conductive wire 6, then the conductive wire 6 is continuously driven to gradually approach the inner wall of the rubber shell 5 until the wire pressing part contacts the inner wall of the rubber shell 5, at the moment, the driving unit 2 continuously drives the wire pressing unit 1 to move forwards, at the moment, the front side of the wire pressing part 102 is limited by the inner wall of the rubber shell 5 and the conductive wire 6, and the rear side is driven by the driving unit 2 to start to deform. On the one hand, the deformation of the wire pressing part can absorb the pressure caused by the driving unit 2, so that the damage to the paint skin caused by the overlarge pressure applied to the conductive wire 6 by the wire pressing part 102 is avoided, on the other hand, the contact area between the wire pressing part 102 and the conductive wire 6 is gradually increased when the wire pressing part is deformed, the limitation on the conductive wire 6 is increased, so that the conductive wire is tightly adhered to the inner wall of the rubber shell 5 according to the standard, and most importantly, the conductive wire 6 forms a buffer arc at the position, which is close to the junction between the bottom surface and the side surface of the rubber shell 5, of the contact part between the wire pressing part 102 and the conductive wire 6, so that the production requirement of a network filter is met.

Example 2:

this embodiment is further optimized and defined on the basis of embodiment 1.

As shown in fig. 5, the pressing portion 102 has a triangular prism shape, and is an edge at the closest distance from the conductive wire 6 along the moving direction. The line drawing is carried out along the movement direction of the line pressing part 102, the edge of the triangular prism-shaped line pressing part 102 is nearest to the conductive line 6, and when the line pressing part 102 is pressed to start to deform after being contacted with the conductive line 6, the contact area between the line pressing part 102 and the conductive line 6 is remarkably increased, and the conductive line 6 is more favorable to be fixed on the inner surface of the rubber shell 5 according to production standards.

In this embodiment, as shown in fig. 7 and 8, the moving direction of the wire pressing unit 1 and the surface of the wire pressing portion 102 form an acute angle with the horizontal plane of the coil 4. With the arrangement direction of the coil 4 as a reference, as shown in fig. 1, which is a schematic structural diagram of the front view direction of the application, the normal line of the surface of the wire pressing part 102 forms an acute angle with the coordinate line in the vertical direction, that is, the wire pressing part 102 is arranged obliquely upwards relative to the coil 4, the movement direction of the wire pressing unit 1 is equal to the movement direction of the wire pressing part 102, the movement direction is adapted to the arrangement direction of the wire pressing part 102, and the inclined downward movement track is formed. Then, after the wire pressing portion 102 gradually approaches the conductive wire 6, the edge at the front end of the wire pressing portion 102 contacts the conductive wire 6 first, and continues to move to make most of the conductive wire 6 contact the inner wall of the rubber case 5, as shown in fig. 7, if the remaining amount of the conductive wire 6 in the rubber case 5 is insufficient, the coil 4 may be pulled up, so that the coil 4 originally placed on the bottom surface of the rubber case 5 is suspended, and since the wire pressing unit 1 is inclined in this embodiment, when the distance between the wire pressing unit 1 and the coil 4 is appropriate, as the wire pressing unit 1 gradually approaches the conductive wire 6, as shown in fig. 8, the bottom surface contacts the surface of the coil 4, and the coil 4 may be pressed and fixed on the bottom surface of the rubber case 5.

In this embodiment, as shown in fig. 3, 5 and 6, the pressing unit 1 includes a mounting panel 101, and one end of the mounting panel 101 is embedded in and fixedly connected to the pressing portion 102. In this embodiment, the installation panel 101 is used to fix the wire pressing portion 102, and the rigid installation panel 101 is used to connect the fixing tool 3 and cooperate with the driving unit 2, and provide the flexible wire pressing portion 102 with the installation medium, so that the pressing of the coil 4 by the wire pressing unit 1 is actually realized in a form that the bottom surface of the installation panel 101 contacts with the surface of the coil 4.

In addition, in order to adapt to the processing technology of arranging a plurality of network filters in parallel and winding wires simultaneously in a full-automatic production line, as shown in fig. 5, a plurality of mounting teeth which are distributed at intervals are arranged in parallel at the matching position of the mounting panel 101 and the wire pressing part 102, and the wire pressing part 102 corresponds to the mounting teeth one by one. The width of each mounting tooth corresponds to the distribution width of a plurality of conductive wires 6 in one network filter, and then the wire pressing part 102 on one mounting tooth is used for pressing the conductive wires 6 on one side in one network filter, and the number of the mounting teeth corresponds to the number of the network filters wound at one time in the production line.

Example 3:

the structure of the fixing tool 3 is further optimized and limited based on the above embodiments.

As shown in fig. 3 and 4, the fixing tool 3 includes a base 301, and an installation seat 302 detachably connected with the base 301, a sliding rail 3022 and a sliding seat 303 slidably matched with the installation seat 302 through the sliding rail 3022 are disposed on the surface of the installation seat 302, and the surface of the sliding seat 303 is fixedly connected with the power output ends of the installation panel 101 and the driving unit 2. In this embodiment, the base 301 is a component of a fixed part such as a bracket and other structural connection in the production line, the detachable connection between the mounting base 302 and the base 301 is convenient for adjusting the inclination angle of the mounting base 302 in the installation stage of the device, the surface of the mounting base 302 is in sliding fit with the sliding base 303 through the sliding rail 3022, and the sliding base 303 is fixedly connected with the power output ends of the wire pressing unit 1 and the driving unit 2, so that when the driving unit 2 provides power, the sliding base 303 is pushed to move, and the sliding base 303 drives the wire pressing unit 1 to synchronously move. It should be noted that the specific implementation of the drive unit 2 includes, but is not limited to, a telescopic cylinder as shown.

In this embodiment, an example is provided for the way of matching between the mounting base 302 and the base 301, as shown in fig. 4, the mounting base 302 is matched with the base 301 by a screw, and a waist-shaped groove 3021 is provided on the mounting base 302 at the position where the mounting base 302 is matched with the screw. In this embodiment, when the mount 302 rotates relative to the base 301 to adjust the inclination angle of the wire pressing unit 1, the center of rotation thereof is not coincident with the connection between the mount 302 and the base 301, and therefore, the waist-shaped groove 3021 is provided on the mount 302 to increase the range of angles in which the mount 302 can rotate relative to the base 301.

Example 4:

in this embodiment, the material and hardness of the pressing line portion 102 are further limited in addition to the above embodiments. The wire pressing part 102 is made of silicone rubber with the hardness of 50-70 degrees. The characteristic of elastic deformation of the wire pressing portion 102 is that after the wire pressing winding is completed in production, the wire pressing portion 102 can quickly recover the shape when the driving unit 2 drives the wire pressing unit 1 to recover to a position far away from the conductive wire 6. Meanwhile, since the main function of the wire pressing portion 102 in the present application is to press the conductive wire 6, the hardness thereof is too low, which does not affect the formation of the buffer arc, but easily causes the deflection of the conductive wire 6, and the selection of the hardness higher than that of the conventional silicone is beneficial to control the deformation amount of the wire pressing portion 102.

The flow of crimping by using the crimping tool will be further described based on the preferable material and hardness of the crimping portion 102 provided in the present embodiment. The wire pressing mechanisms on two sides move along the movement track with the plane of the inner bottom surface of the jig or the rubber shell 5 as a reference at an acute angle, referring to fig. 7 and 8, the coil 4 is fixed at the inner bottom of the rubber shell 5, the inner walls on two sides of the rubber shell 5 are higher, and the conductive wire 6 itself is always stressed at two ends of the conductive wire 6 by adopting a vertical pressing mode in a stretching state. Since the conductive wire 6 is generally an enameled wire or a rubber wire and is made of a polymer material such as silica gel, the wire pressing portion 102 deforms when contacting the conductive wire 6 and forms a large static friction force with the surface of the conductive wire 6 in the contact portion. Because of the large static friction force, the two ends of the wire are stressed, and as can be seen in fig. 7, the gap between the coil 4 and the inner wall of the rubber shell 5 is small, and if the wire pressing part 102 is directly inserted downwards, the end of the wire pressing part can only contact with the part of the conductive wire 6 close to the coil 4, so that the conductive wire 6 at the position of the coil 4 which is installed by bottoming is easily broken.

In this embodiment, the wire pressing portion 102 inserted into the rubber housing 5 at an acute angle can be abutted against the conductive wire 6 near the inner wall of the rubber housing 5, and the conductive wire 6 is continuously bent downward after contacting to form the downward pulling of the wire pressing portion 102 in fig. 8, at this time, the portion of the conductive wire 6 at the coil 4 is not stressed or stressed less, but the conductive wire 6 located outside the rubber housing 5 is pulled into the rubber housing 5 to form a buffer arc.

Further, through setting up to sharp angle contact deformation's line ball portion 102 structure, cooperate its hardness index, can continue to support it on the inner wall of the gluey shell 5 with it after contacting conductive wire 6, be downlinked by self crooked, the line ball portion 102 of other hardness or material is too soft to lead to its use for a period unable elastic recovery needs to change, and the life-span is shorter, or is too hard to lead to conductive wire 6 to be directly pulled apart on the inner wall of gluey shell 5. In this embodiment, the materials are preferable to meet the long-term use requirement.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
