Description

Winding pin head of network filter

Technical Field

The invention belongs to the technical field of inductance manufacturing equipment, and particularly relates to a winding pin head of a network filter.

Background

The function of the filter is to allow the signals of a certain part of frequencies to pass smoothly, while the signals of another part of frequencies are greatly suppressed, and the filter is essentially a frequency selection circuit. The frequency range in the filter through which a signal can pass is called a passband or passband; conversely, the frequency range in which the signal is greatly attenuated or completely suppressed is called the stop band; the dividing frequency between the pass band and the stop band is called the cut-off frequency; the voltage gain of the ideal filter in the pass band is constant, and the voltage gain in the stop band is zero; a transition band of a certain frequency range exists between the pass band and the stop band of the actual filter.

The network filter comprises a shell and a plurality of pins, wherein the pins are uniformly embedded at the upper end and the lower end of the shell, a magnetic ring is arranged in a groove of the shell, and the magnetic ring is connected with the pins through coil leads. When the filter is used for winding, besides the winding of the inner magnetic ring, the enameled wire is wound on the pin, and the redundant wire is cut off, wherein the winding is performed in the process of winding the pin.

The main bottleneck of improving the production efficiency of the network filter module is the welding of the enameled wire of the magnetic ring and the input/output pin, and the winding pin needs to be fixed before welding. Compared with the traditional method, the method comprises the steps of carefully winding the enameled wire on the pins by using tweezers through a large amount of manpower, cutting off redundant enameled wire ends after winding, then carrying out tin immersion welding, cleaning welding points after welding, and treating poor welding. The main advantage of the process is that the cost of the input equipment is low, but the process is typical labor-intensive operation, and the human uncertainty factor is large. The network filter/transformer is small in size, and different types of the network filter/transformer can have different numbers of pins; each pin is small in size, and the winding mode on each pin is different, so that the efficiency of the existing manual processing mode is low, the yield is low, and the cost is high.

In order to improve the current situation, some prior arts provide an automatic winding device and process, such as an automatic winding device and a winding method for network transformer production with patent number CN202110977457.8, wherein a winding needle structure is disclosed, which uses a structure of a wire hanging port to hook an enameled wire for winding. However, the size of the wire hanging opening structure is necessarily small because the wire hanging opening structure is required to stably hook the enameled wire for winding, and difficulty is high when the multi-part cooperative winding is carried out at the size and the enameled wire is successfully hooked. The off-hook condition is easy to occur in the actual operation, and the partial pins of the partial network filter after winding are not successfully wound, so that the reworking or the material scrapping is caused.

Simultaneously, this kind of mode of directly catching on the line then coiling on the pin leads to the enameled wire to appear scraping the condition of peeling and lead to product trouble because the comparatively sharp-pointed border of square pin in the coiling process most easily.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides the winding pin head of the network filter, and the equipment can reduce the cost by changing the winding mode under the condition of ensuring the yield as much as possible.

The technical scheme adopted by the invention is as follows:

the invention discloses a winding pin head of a network filter, which is used for guiding and winding an enameled wire into a coil in the pin winding of the network filter.

The invention adopts a clamping winding mode, and the wound coil is firstly attached to the guide head and then falls onto the corresponding pin from the guide head. The wire winding clamping mode has high stability during wire winding, the wound cable has certain width by adjusting the size of the guide head, and even if a certain amount of positioning error or movement error exists, the cable can smoothly fall on the pin.

The guide head can be used in a manual or mechanical automatic winding process, the existing cable is directly wound on the pin, the size of the existing cable is inevitably smaller no matter the cross section shape of the pin, and the situation that the paint skin falls off or is broken is easily caused by the excessively fast bending and the smaller bending radius. The core of the present invention is different in that the guiding head structure is provided and has a conical transition section, so that the winding forms a coil outside the pin and falls down, and the coil is pulled tightly after falling.

It should be noted that the term "tapered transition" means that the guide head has a rod-like structure at one end, and the outer side of the cross section of the guide head, which is taken transversely to the axis, has an angle with respect to the axis, which is not zero. And the toper is only used for referring to this part and has an inclined plane, and this inclined plane is polished comparatively smoothly for the leather-covered wire also can fall smoothly after contacting its surface. The inclined angle comprises different modes of fixed angle and multi-section angle change, and the multi-section angle change comprises two modes of step change and arc smooth transition.

Regardless of the angle change mode, the cross section of the steel plate is required to have a continuously reduced outer diameter after transversely cutting in the direction perpendicular to the axial line. The reduction means that the lead head is reduced toward the lead side during winding, and the sectional dimension is a section which is transversely crossed perpendicular to the axial direction, and the section can be regarded as monotonous size change in space.

Because the cross-sectional dimension grow obviously can't play the guide effect, the varnished wire of coiling can paste and can't fall on the guide head. The straight rod surface can not guide the paint leather line to fall, and the paint leather line can not fall due to friction. Only the guide head with the inclination angle can enable the enameled wire coil which is attached to the surface of the winding to normally fall down, and meanwhile, the winding speed can be adjusted to enable the enameled wire to fall down in a space spiral mode, and the situation of mutual friction between the enameled wires can be reduced.

In combination with the first aspect, the present invention provides a first embodiment of the first aspect, wherein the tapered transition section comprises a third tapered transition section, and the outer sidewall inclination angle of the third tapered transition section is 10 ° to 60 °.

It should be noted that the inclination angle of the outer sidewall is the inclination angle in the above description. In practice, even if a conical transition section with a continuously reduced cross section exists, the problem that the enameled wire coil cannot fall off smoothly or in the time meeting the process requirements and other conditions exists.

An excessively small inclination angle cannot provide a guide effect, and the falling speed is excessively slow. An excessive inclination angle may result in an excessive falling speed or an ineffective contact with the enamel wire to form a coil. This range of angles is considered to be the lowest condition that will enable sustainable production in the process.

In combination with the first embodiment of the first aspect, the present invention provides the second embodiment of the first aspect, and the inclination angle of the outer sidewall of the third conical transition section is further preferably 15 ° to 35 °.

In combination with the first embodiment of the first aspect, the present invention provides a third embodiment of the first aspect, wherein the inclination of the outer sidewall of the third conical transition section is still further preferably 25 ° -32 °

In combination with the first embodiment of the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the end of the guide head has an inward recessed slot, and the pin is inserted into the slot and abuts against the guide head.

It should be noted that the size of the slot is slightly larger than the size of the end of the pin. No matter it is manual or automatic wire winding processing, all can lean on the guide head on the pin for it is spacing that the pin can insert the joint that realizes certain degree in the slot.

With reference to the first or second or third or fourth embodiment of the first aspect, the invention provides a fifth embodiment of the first aspect, wherein the guide head comprises at least two sections with different inclination angles of the outer side wall, the third conical transition section is located at the outermost side, and the enamel wire is wound around the third conical transition section.

With reference to the fifth implementation manner of the first aspect, the invention provides the sixth implementation manner of the first aspect, and further includes a wire clamp which is matched with the guide head, and the wire clamp is a movable member and rotates with an axis of the guide head as a central axis.

With reference to the sixth implementation manner of the first aspect, the invention provides a seventh implementation manner of the first aspect, wherein the wire clamp is fixedly connected with the guide head and movably connected to an external structure, and the rotation of the wire clamp is controlled by a power mechanism.

With reference to the sixth implementation manner of the first aspect, the invention provides an eighth implementation manner of the first aspect, wherein the wire clamp is movably connected with the guide head, and the rotation of the wire clamp is controlled by an external power mechanism.

With reference to the sixth implementation form of the first aspect, the invention provides the ninth implementation form of the first aspect, further comprising a fixing sleeve, wherein the fixing sleeve and the wire clamp are relatively static along the axis of the guide head;

the guide head is movably connected with the fixed sleeve and can perform linear reciprocating motion relative to the fixed sleeve along the axial direction of the guide head.

The invention has the beneficial effects that:

(1) according to the invention, the enameled wire is wound on the guide head, and then the formed coil falls from the winding head to the pins to be formed, so that the high yield is achieved, and the cost is better controlled;

(2) the wire clamp is matched with the guide head, so that manual or automatic winding is realized;

(3) according to the invention, the inclination angle of the guide head is optimized, so that the varnished wire wound on the guide head can smoothly and stably fall, and the condition that an insulating layer of the varnished wire is invalid or broken can be reduced in the winding process.

Example (b):

the embodiment discloses a winding foot head of a network filter, which is mainly used on a manual or mechanical automatic production line, and after a plurality of network filters are fixed by an external jig, corresponding enameled wires are wound on the winding foot head, and a coil formed by the enameled wires can just fall on pins of the corresponding network filters under the influence of external force or the gravity of the enameled wires, so that the winding operation is completed.

First, the network filter of this embodiment has a housing, and a plurality of coil magnetic rings are disposed in the housing. The magnet ring of the embodiment is formed by winding the enameled wire through other winding processes, and only the enameled wire with a certain length at the end part is left.

The processing technology corresponding to the device of the embodiment is that wire arrangement processing is already carried out before the processing technology corresponding to the device, the end wire harness of the magnetic ring in the network filter is well arranged, and the end wire harness is fixed through a fixing groove on a jig. Therefore, the middle part of the jig is provided with a plurality of inverted network filters, pins on two sides of each inverted network filter are arranged upwards, a plurality of fixing grooves are formed in two sides of each inverted network filter to fix the end part wire harness, and a certain space is reserved between each fixing groove and each pin to facilitate external equipment to clamp or lift the part of the wire harness.

Specifically, the foot surrounding head of the present embodiment has at least one leading head 2 structure, and as shown in fig. 1, the leading head 2 has a rod-shaped structure with at least one conical transition section. Through with the enameled wire coiling on this toper changeover portion for the enameled wire can fall along the direction that toper changeover portion cross-section diameter reduces under the influence that receives external force or self gravity, thereby falls on the pin.

The lead into which the coil falls as defined in the present embodiment refers to an inner end portion of the lead which is a bent metal strip in which an outer portion has a bent end portion for connecting an external circuit. The inner part is also provided with an end part which is protruded in the same direction as the outer bending end part, and the connection with the pin is realized by winding the enameled wire of the inner coil magnetic ring on the end part.

Preferably, the tapered transition section is defined by the slope of the outer side of the cross section transverse to the axial direction, and at least has a transition section with a constant slope of the cross section, namely a standard tapered transition shape, and the inclination angle of the transition section ranges from 10 degrees to 60 degrees, wherein the inclination angle refers to the included angle of the outer side and the axial direction.

Or, the conical transition section is limited by the slope of the outer side of the section after transverse cutting along the axial direction, at least has the transition section of which the section slope is changed by a fixed multiple, and the external shape of the transition section is similar to a convex curved surface.

Or, the conical transition section is limited by the slope of the outer side of the section after transverse cutting along the axial direction, at least has the transition section with the section slope changing from large to small, and the external shape of the transition section is similar to a concave curved surface.

Preferably, in the embodiment with the same slope, the tapered transition section includes two transition sections with different slopes, namely, the third tapered transition section 2.4 and the second tapered transition section 2.3. The outer side edge of the third conical transition section 2.4 is inclined at an angle ranging from 15 to 35 degrees. While the slope of the second tapered transition section 2.3 is any value in the range of greater than the outboard edge angle of the third tapered transition section 2.4 but less than 60. And during winding, only the enameled wire is wound on the third conical transition section 2.4, and the third conical transition section 2.4 is also close to the tail end of the pin.

Preferably, the tapered transition section comprises three transition sections with different slopes, namely a third tapered transition section 2.4, a second tapered transition section 2.3 and a first tapered transition section 2.2 which extend outwards in sequence near one end of the pin. Wherein the transition sections are all connected smoothly and are subjected to surface polishing treatment.

Wherein the outer side edge of the third conical transition section 2.4 has an inclination in the range of 25-32. While the slope of the second tapered transition section 2.3 is greater than the outboard edge angle of the third tapered transition section 2.4 but less than any value within the range of 60 deg., and the slope of the first tapered transition section 2.2 is greater than the outboard edge angle of the second tapered transition section 2.3 but less than any value within the range of 60 deg..

Or the conical transition section comprises three transition sections which have different slopes and are connected end to end, namely a third conical transition section 2.4, a second conical transition section 2.3 and a first conical transition section 2.2 which extend outwards in sequence from one end of the pin.

Wherein the outer side edge of the third conical transition section 2.4 has an inclination angle in the range of 25-32 deg. While the slope of the second tapered transition section 2.3 is any value in the range of less than the outboard edge angle of the third tapered transition section 2.4 but greater than 10 deg., and the slope of the first tapered transition section 2.2 is any value in the range of greater than the outboard edge angle of the second tapered transition section 2.3 but less than 60 deg..

Preferably, since the first tapered transition section 2.2 and the second tapered transition section 2.3 are not in contact with the enamel wire (only the theoretical condition is set, but there may be a contact condition in the actual operation, the present embodiment mainly uses the third tapered transition section 2.4 as the guiding surface), and only serves as the transition cutting treatment process of the third tapered transition section 2.4. Since the entire guide head 2 is a solid, smooth-surfaced metal rod, it is necessary to machine it to form a tapered transition at the end. While the lead head 2 itself has a minimum diameter parameter, but its end cross-sectional dimensions should be close to the dimensional range of the individual pin ends. And the length of the whole conical transition section is limited to a certain extent, the overlarge slope cannot meet the winding requirement, and the undersize slope cannot reduce the section diameter of the transition section to the size of the end part of the pin. The end of the guide head 2 needs to maintain a certain cross-sectional diameter in order to maintain its structural strength, but in order to obtain a proper inclination angle, the cross-sectional diameter is reduced by two conical transition sections while ensuring the structural strength.

Wherein h1, h2 and h3 are shown in fig. 3 as length scales of the corresponding first conical transition section 2.2, second conical transition section 2.3 and third conical transition section 2.4. It can be seen that the optimum value of the angle of inclination of h3 is around 30 °, whereas h2 is only 20 ° and h1 is 24.5 °. And (h 3+ h 2): the height ratio of h1 is 8: about 7.

Preferably, an inwardly recessed slot 2.1 is further provided in the end surface of the lead 2, the width of the slot 2.1 being slightly larger than the end surface dimension of the pin, so that the pin can be inserted into the slot 2.1 and abut against the lead 2. Meanwhile, the third conical transition section 2.4 is arranged for processing, so that the edge of the slot 2.1 is sharp, and the condition that the pin directly abuts against the edge of the slot 2.1 and cannot enter the slot is reduced by reducing the area of the annular surface of the outer edge of the slot 2.1.

It is worth noting that for the third conical transition section 2.4, the preferred inclination angle is the most suitable range determined during engineering practice.

The effect of guide enameled wire whereabouts can't be played in the inclination of undersize because the enameled wire itself has one deck insulating layer, and guide head 2 is the metal material, though the surface is smooth, the enameled wire also can laminate at guide head 2 surfaces at the wire winding in-process. If the dip angle is not large or too small, the gravity of the enameled wire cannot overcome the friction force of the enameled wire, so that the enameled wire cannot fall smoothly.

And the too large inclination angle can not play the effect of guiding the enameled wire to wind, so that the enameled wire quickly falls down and does not form a coil.

In order to verify and obtain the optimal inclination angle range and the optimal angle, the guide head 2 is fixed on the upper part of any pin of the network filter, then the enameled wire clamp 4 with the same specification is wound by three circles by adopting the same clamp, and then the enameled wire clamp is tested in two modes of autonomous falling and guided falling respectively, and then the result and the yield are checked.

Wherein, only the inclination angle of the third conical transition section 2.4 and trial production of a plurality of samples are tested, the inclination angle of the tested sample of the guide head 2 comprises a straight rod control group without the inclination angle and 16 groups of experimental groups which are continuously increased to 80 degrees by an angle difference of 5 degrees, and each experimental group tests 200 windings.

And then judging the yield and the winding completion time of each experimental group. First, it was determined that the yield of the experimental groups below 5 ° and 65 ° and above was below 50%, especially with the autonomous drop process, more than 80% of the coils could not fall completely onto the pins in samples with an angle less than 5 °. Then, the preferred angle range is determined within the range of 5 to 65. Wherein, the yield of the experimental group within the range of 15-35 degrees is higher than 90 percent, and the autonomous falling rate is higher than 90 percent. Whereas the yield in the 25 ° and 30 ° experimental groups was higher than 98% and both were able to fall off by themselves. Then, an additional experiment is carried out for the upper limit of 30 degrees, and the optimal upper limit range is determined to be about 32 degrees.

Then, the average winding time of the experimental group of the guide heads 2 with the inclination angle of 10 ° or less is lower than the process requirement, and the minimum process standard can not be achieved. When the angle is less than 25 degrees, the self-dropping rate of the coil is below 95%, and the coil cannot automatically drop in the test sample. The optimal angle range is determined to be between 25 and 32 degrees in order to ensure the winding success rate of the coil as much as possible.

It should be noted that the yield includes the detection of both the wire winding condition and the product test, and even if the foot winding process is finished in the appearance inspection of some products, the enameled wire is damaged to affect the service performance, and cannot be calculated as a qualified product. It should be noted that, in the prior art, there is no guiding structure for winding the pin enameled wire of the network filter/transformer, and the above experimental data only reflects the correlation between the enameled wire and the inclination angle at the size, once the wire size or material is changed and the pin size is changed, the effect of the enameled wire falling cannot be expected, and other experiments or implementations cannot reflect the technical effect.

Preferably, as shown in fig. 7, the foot head further comprises a fixing sleeve 1. The end of the fixing sleeve 1 has a blind hole with a certain length, and the end of the guide head 2 which is not provided with the conical transition section can be inserted into the blind hole of the bushing 3 and linearly reciprocate along the axis of the blind hole.

Wherein, still be equipped with reset spring 8 in fixed cover 1, be equipped with logical groove on the fixed cover 1. And a group of fixing rods 7 are arranged on the outer side surface of the guide head 2. Wherein the fixing rod 7 is inserted into and penetrates through the through groove, and the guide head 2 is limited through the through groove, so that the fixing sleeve 1 can only perform linear motion with a certain length. And the spring 8 provided between the inner end of the blind hole and the end of the guide head 2 can always give the guide head 2 an outward elastic force.

Because this guide head 2 tip has slot 2.1, the pin tip inserts in slot 2.1 when the wire winding and realizes leaning on fixedly, then spring 8 can just contract in advance before the external force that exerts surpasss the biggest bearing capacity of pin and cause guide head 2 can inwards contract to avoid causing the destruction to the pin.

Preferably, the winding head is a winding structure having a clamp and applied to a robot, as shown in fig. 4-6. The wire clamp comprises a bushing 3, a wire clamp 4, a fixed shaft sleeve assembly 5 and a rotating wheel 6. First the guide head 2 is arranged in the fixing sleeve 1, while the fixing sleeve 1 is fixed in the bushing 3.

One end of the wire clamp 4 is fixedly connected with the bush 3 through a bolt, and the whole bush 3 is rotatably connected with an external fixed frame through a fixed shaft sleeve assembly 5. The upper end of the bush 3 is provided with a rotating wheel 6, and the rotating wheel 6 is in transmission connection with an external belt transmission mechanism.

The wire clamp 4 is of a pneumatic control structure, two clamping arms are arranged at the end part of the wire clamp, and the clamping arms are controlled to move to clamp through an air cylinder in an external cable controller.

Since the clip 4 is provided on one side of the bush 3 and is kept in relative movement with the bush 3 in the axial direction. And the guide head 2 can contract inwards, the guide head 2 can contract by applying a downward pressure on the whole bushing 3 during winding, and the position of the end of the wire clamp 4 continuously moves downwards.

Because the rotating wheel 6 is connected with an external belt transmission mechanism, power is provided by the belt transmission mechanism to control the rotation of the rotating wheel. The rotating wheel 6 is coaxially and fixedly connected with the bushing 3, and the bushing 3, the fixed sleeve 1 and the guide head 2 are also coaxially and fixedly connected. Then rotate with the axis of guide head 2 during the rotation, and fastener 4 makes it wind on guide head 2 through the enameled wire of cliping on the tool to fall into and accomplish when a winding operation on the corresponding pin after forming the coil.

Preferably, the plurality of foot winding heads of the present embodiment may be arranged side by side on the same fixed frame, as shown in fig. 8, and the fixed frame is further arranged on a moving frame moving on a plane, and the relative position relationship of the moving frame and the fixed jig on the table top is adjusted, so as to perform the automatic foot winding operation.

The equipment has four winding pin heads, the fixing frame has one fixing end face, and four winding modules are fixed on each fixing end face at equal intervals. The holder has a lateral space for placing a plurality of wheels 6. A pair of pinch rollers is respectively arranged at the gap of each adjacent rotating wheel 6 in the space, and the pinch rollers tension the belt sleeved outside the rotating wheels 6. The motor is arranged at one end of the fixed frame, and the rotating wheel 6 of the output shaft of the motor is kept on the same horizontal plane with other rotating wheels 6.

Furthermore, this mount still has the lead screw motion controller that two mutually perpendicular motion are connected, promotes the mount by two lead screw motion controllers and carries out vertical and horizontal migration in the space to compare and carry out relative position in single or a plurality of tool of fixing on the mesa and remove, thereby can lift up rapidly and remove behind a pin position and continue to carry out the wire winding operation to adjacent pin after four wire winding foot heads accomplish the wire winding operation of single pin.

Further, as shown in fig. 9, the automatic device with a plurality of winding pin heads is assembled on the table top and matched with the transmission device, so that an automatic winding assembly line can be formed.
