Description

Automatic winding displacement mechanism and wire winding equipment

Technical Field

The application relates to the technical field of 3D printing consumable production, in particular to an automatic wire arranging mechanism and wire winding equipment.

Background

3D printing is a rapid prototyping technology, also called additive manufacturing, which is a technology for constructing objects by using powdery metal or plastic and other bondable materials in a layer-by-layer printing mode based on digital model files.

The 3D printing wire is generally produced by an extrusion process, and after the wire is extruded and molded, the wire needs to be wound on a wire coil, so that the wire is convenient to transport and use.

Since the wire rod contains soft materials, certain tension is applied to the wire rod during winding after extrusion molding, so that the wire rod maintains a certain stretching amount, but if the tension is too large, the wire rod is easily subjected to stretching deformation, so that the sectional area of the wire rod is reduced, and the quality of the wire rod is affected. When the wire is wound on the wire coil, the tension of the wire is increased continuously along with the increasing of the number of winding layers of the wire. After the cross-sectional area of the wire rod is increased to a certain extent, the cross-sectional area of the wire rod is smaller than the standard value required by products, so that defective products appear and the wire rod is possibly broken.

3D printing is typically implemented using a digital technology material printer. Are often used in the field of mold manufacturing, industrial design, etc. to make models, and then gradually used for direct manufacture of some products. The technology has application in jewelry, footwear, industrial design, construction, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and other fields.

3D printing is typically implemented using a 3D printer. Extrusion 3D printing (me-3 DP) is one of the most dominant forms of polymer Material additive manufacturing technology. In extrusion 3D printing technology, wire melt fabrication (Fused Filament Fabrication, FFF) is one of the mainstream technical forms. The principle is that a printing nozzle of a 3D printer is used for melting a polymer material at high temperature, so that the polymer material obtains melt fluidity, and the polymer material is extruded by the printing nozzle in a certain metering mode and then stacked layer by layer for forming.

The linear printing material is used as 3D printing consumables, the variety is complex, and especially with the development of technology, the variety of 3D printing wires is more diversified. The wire for 3D printing may be generally produced using an extrusion line, and for example, 3D printing wires such as PLA (polylactic acid), ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene), PP (polypropylene), PC (Polycarbonate), TPU (Thermoplastic Urethane, thermoplastic polyurethane elastomer), PVC (Polyvinylchloride) and the like may be produced by the extrusion line.

After the wire rod is extruded and molded by the extrusion production line, the wire rod needs to be wound on a wire coil so as to be convenient for transportation and use of the wire rod. As shown in fig. 1, the winding process steps of the 3D printing wire are approximately as follows:

s1, mounting a wire coil (hereinafter referred to as an empty wire coil) which is not wound with wires on an automatic winding mechanism;

s2, fixing the front end of the wire rod produced by the production line with a bottom hole of an empty wire disc on the automatic winding mechanism;

s3, starting an automatic winding mechanism to drive the empty wire coil to rotate so as to wind the wire rod onto the empty wire coil;

s4, cutting the wire after the winding of one wire coil is completed, and fixing the tail end of the wire formed by cutting the wire with the wire coil;

S5, taking off a wire coil wound with wires (hereinafter referred to as a full coil) for weighing, classifying and stacking, and loading a new empty coil on an automatic winding mechanism for winding in the next round.

Most of the current winding devices need to participate in each step manually when the winding process is performed, so that the production efficiency is low, and the problem of product quality caused by manual misoperation is likely to occur.

In view of this, some embodiments of the present application provide a wire winding apparatus capable of implementing automatic online winding of 3D printed wires, thereby improving production efficiency, reducing human participation, and avoiding product quality problems caused by human misoperation.

The application is described in detail below with reference to the attached drawing figures:

fig. 2 and 3 show a wire winding apparatus including an automatic loading and unloading mechanism 100, an automatic wire arranging mechanism 200, an automatic wire winding mechanism 300, an automatic wire ending mechanism 400, and an automatic finished product taking weighing mechanism 500. The automatic feeding and discharging mechanism 100 is used for transporting empty wire reels and full wire reels, and specifically can be used for executing the step S1, namely, loading the empty wire reels into the automatic winding mechanism 300 through the automatic feeding and discharging mechanism 100. The automatic wire arranging mechanism 200 and the automatic wire winding mechanism 300 cooperate to execute the step S2 and the step S3, firstly, the front end of the wire rod automatically penetrates into the bottom hole 804 of the wire coil 800 and is fixed, then, the automatic wire winding mechanism 300 drives the wire coil 800 to rotate, and simultaneously, the automatic wire arranging mechanism 200 adjusts the winding position of the wire rod on the wire coil 800, so that the wire rod is wound on the wire coil 800 according to a preset wire arranging mode. The preset wire arranging mode can be selected according to practical conditions, for example, the left end of the wire coil is arranged to the right end, and then the right end is arranged to the left end; or firstly, arranging wires from the right end to the left end of the wire coil, and then arranging wires from the left end to the right end of the wire coil; it can also start from the middle of the wire coil, firstly lay wires to the left end and then to the right end, etc. The automatic tail wire winding mechanism 400 is used for executing step S4, namely cutting off the tail end of the wire after winding, and fixing the tail end of the wire with the wire coil 800. The automatic take-off weighing mechanism 500 is used to perform step S5, i.e. take off the full coil and weigh. The automatic feeding and discharging mechanism 100 may also be used for performing the second half of the step S5, i.e. sorting and stacking the weighed full reels. The steps can be automatically completed, so that the production efficiency of the wire rod can be improved, the manual participation is reduced, and the product quality problem caused by manual misoperation is avoided.

In addition to the above-described mechanisms, the wire winding apparatus may include a turnover vehicle 600 for placing the wire reels 800, a frame 700 for supporting the entire apparatus, and the like, as shown in fig. 3. The transfer cart 600 may be used to stack empty reels and full reels. The storage mode has various options, for example, as shown in fig. 3, the turnover vehicle 600 may be provided with 8 storage bins, each storage bin may store 16 wire reels 800, and the wire reels 800 are sequentially stacked in the storage bins along the vertical direction. Of course, other storage modes can be selected according to production requirements, for example, 3, 4, 5, 6, 7, 9, 10 storage bins can be arranged. Each storage bin can also be provided with 5, 8, 9, 10, 15, 18, 20 and the like coils 800.

One possible configuration of the wire coil 800 is shown in fig. 4. The wire coil 800 may include a wire winding roller 801 and limit stops 802 disposed at both ends of the wire winding roller 801. The winding roller 801 is used for winding wires, and the limiting baffle 802 is used for limiting the wires wound on the winding roller 801 so as to prevent the wires from falling off from two ends of the winding roller 801. The central hole 803 is formed in the middle of the winding roller 801 along the axial direction, the central hole 803 penetrates through the limit baffles 802 at two ends of the winding roller 801, and the central hole 803 can be used for the automatic feeding and discharging mechanism 100 to clamp the wire coil 800 and also can be used for the automatic winding mechanism 300 to position the wire coil 800 during winding. The bottom hole 804 of the wire coil 800 is formed on the side wall of the winding roller 801 and is communicated with the central hole 803, and the bottom hole 804 is used for being fixed with the end of the wire so as to preliminarily position the wire and the wire coil 800 before winding.

The following describes each mechanism of the wire winding device in detail by combining the winding process:

before executing step S1, empty wire coils can be stacked in a storage bin of the turnover vehicle 600 along a vertical direction, and then the turnover vehicle 600 filled with the empty wire coils is moved to a material taking station of the wire winding device, and the turnover vehicle 600 is limited, so that the turnover vehicle 600 is prevented from moving in a material taking and discharging process.

After the wire winding device is started, the automatic feeding and discharging mechanism 100 performs step S1, and the automatic feeding and discharging mechanism 100 moves to above the turnover vehicle 600, picks up the wire coil 800 in the vertical direction, and moves to the automatic winding mechanism 300. As shown in fig. 3, the automatic feeding and discharging mechanism 100 includes a pick-and-place device 110 and a moving device 120, where the pick-and-place device 110 is used for picking up or placing the wire coil 800, and the direction of picking up and placing the wire coil 800 may be a vertical direction. The moving device 120 is connected to the pick-and-place device 110, so as to drive the pick-and-place device 110 to move in a horizontal plane to transport the wire coil 800.

In one application scenario, the wire coil 800 is placed horizontally in the turnover vehicle 600, and the wire coil 800 is mounted vertically on the automatic winding mechanism 300. Therefore, the automatic feeding and discharging mechanism 100 is required to turn the wire coil 800 by 90 ° to turn the wire coil 800 into a vertical state and then mount the wire coil 800 on the automatic winding mechanism 300 after taking the wire coil 800 out of the turn-around vehicle 600. In order to achieve the above-mentioned process, as shown in fig. 5, the pick-and-place device 110 includes a first clamping assembly 111, a rotating assembly 112, and a vertical moving assembly 113, wherein the first clamping assembly 111 is used for clamping the wire coil 800, and the rotating assembly 112 is used for driving the first clamping assembly 111 to rotate so as to rotate the wire coil 800 from a horizontal state to a vertical state; the vertical axis moving assembly is configured to move the first clamping assembly 111 in a vertical direction to lift or lower the wire coil 800, or to adjust a position of the wire coil 800 in a vertical direction when the wire coil 800 is mounted on the automatic winding mechanism 300.

The first clamping assembly 111 may be implemented in various ways, for example, the wire coil 800 may be clamped by an outer circumference of the wire coil 800, the wire coil 800 may be clamped by a central hole 803 of the wire coil 800, and the wire coil 800 may be clamped in a thickness direction of the wire coil 800. The gripping mode may be specifically selected according to the state of the wire reels 800 in the turnover vehicle 600. For example, the wire coil 800 is horizontally placed in the transfer vehicle 600, and a plurality of wire coils 800 are stacked one on another in the vertical direction, in which case it is difficult to clamp the wire coil 800 by the outer circumference of the wire coil 800 or in the thickness direction of the wire coil 800. Thus, the wire coil 800 may be selectively clamped through the central aperture 803 of the wire coil 800. As shown in fig. 5, the first clamping assembly 111 may extend into the central hole 803 of the wire coil 800, and be fixed relative to the inner wall of the central hole 803 of the wire coil 800 in a manner of expanding and supporting, so as to clamp the wire coil 800.

Specifically, the first clamping assembly 111 may be implemented by adopting a mode that the air cylinder drives the clamping jaw to expand outwards. The rotating assembly 112 may be implemented using a rotating motor. The moving device 120 may be implemented by matching a truss guide rail with a linear transmission mechanism as shown in fig. 5, for example, a motor driving a gear rack to drive, a motor driving a screw nut to drive, or other linear driving modes such as a linear cylinder, a linear motor, etc.

In some specific use cases, the wire coil 800 needs to be separated from the front and the back, and is mounted on the automatic winding mechanism 300 in a predetermined posture. The above-mentioned mounting of the wire coil 800 in the predetermined posture means that the wire coil 800 is mounted to the automatic winding mechanism 300 in a predetermined end face orientation. Assuming that the front surface of the wire coil 800 is mounted toward the driving shaft 320 of the automatic winding mechanism 300, when the wire coil 800 is mounted, the front surface and the back surface of the wire coil 800 need to be adjusted, and then the wire coil 800 is picked up by the automatic feeding and discharging mechanism 100, so that the front surface of the wire coil 800 is mounted toward the driving shaft 320 of the automatic winding mechanism 300. For example, in order to enable the winding of a wire from one end of the wire coil 800 when the wire is wound on the wire coil 800, the bottom hole 804 of the wire coil 800 is typically disposed near the first end or the second end of the wire coil 800. Thus, before each empty coil is installed, in order to ensure that the bottom hole 804 of each empty coil is located at the same position in the axial direction after the installation is completed, the front and back sides of the empty coil need to be identified and adjusted.

In order to automatically implement the above steps of distinguishing and adjusting the front and back sides of the wire coil 800, as shown in fig. 5 and 6, the automatic feeding and discharging mechanism 100 further includes a recognition device 130 and a turning device 140, and the recognition device 130 is configured to recognize or distinguish the front and back sides of the wire coil 800. The identifying device 130 may be mounted on the pick-and-place device 110, and move with the pick-and-place device 110, and when the pick-and-place device 110 is picking up the wire coil 800, the identifying device 130 may identify the front and back sides of the wire coil 800. Thereby saving the operating steps. After the identification device 130 completes the identification, the control system judges whether the wire coil 800 needs to be turned over according to the identification result, if so, the wire coil 800 is conveyed to the turning device 140 for turning over, and if not, the wire coil 800 is directly conveyed to the automatic winding mechanism 300. The turning device 140 can turn the wire coil 800 to a predetermined surface up, such as to a right side up or a reverse side up, according to the identification information of the identification device 130. The front and back surfaces are just two definitions given for distinguishing the two end surfaces of the wire coil 800, and the structures of the front and back surfaces may be the same or different, which is not limited herein.

The identification device 130 may be a camera, a scanner, or the like, and the front and/or the back of the wire coil 800 may be provided with identification marks, so that the identification device 130 identifies the front and the back of the wire coil 800 by photographing or scanning the identification marks. When the recognition means 130 employs a camera, a CCD (charge coupled device ) camera may be employed.

As shown in fig. 6, the turning device 140 includes a fixed bracket 141, a lifting bracket 142, a rotating bracket 143, and a second clamping assembly 144, wherein the fixed bracket 141 is fixedly arranged, and the lifting bracket 142 is slidably arranged on the fixed bracket 141 so as to be capable of moving vertically relative to the fixed bracket 141. The rotating bracket 143 is rotatably disposed on the lifting bracket 142, and the second clamping assembly 144 is disposed on the rotating bracket 143, so that the rotating bracket 143 can drive the second clamping assembly 144 to rotate to turn over the wire coil 800. A wire coil support 145 for placing the wire coil 800 may be disposed beside the turning device 140, after the wire coil 800 is placed on the wire coil support 145 by the first clamping assembly 111, the wire coil 800 is clamped by the second clamping assembly 144 under the driving of the lifting support 142, turned 180 ° under the driving of the rotating support 143, and then discharged from the wire coil support 145, so that the preset surface of the wire coil 800 faces upward. At this time, the first clamping assembly 111 clamps up the wire coil 800 again and rotates it by 90 ° to mount the wire coil 800 on the driving shaft 320 of the automatic winding mechanism 300.

When the empty wire coil is mounted to the automatic wire winding mechanism 300, the automatic wire arranging mechanism 200 and the automatic wire winding mechanism 300 cooperate to perform step S2, wherein the automatic wire arranging mechanism 200 detects the bottom hole 804 of the wire coil 800 and automatically penetrates the front end of the wire into the bottom hole 804 of the wire coil 800, and the automatic wire winding mechanism 300 compresses the wire penetrating into the bottom hole 804 of the wire coil 800. To prevent the end of the wire from being pulled out of the bottom hole 804 during winding.

As shown in fig. 7 and 8, the automatic wire arranging mechanism 200 includes a wire feeder 210, a stage 220, and a stage driving device. The wire feeding nozzle 210 is disposed on the carrying table 220 for guiding the conveying direction of the wire. The carrying table driving device is connected to the carrying table 220, and is configured to drive the carrying table 220 to move, so as to change the position of the wire feeding nozzle 210 relative to the automatic winding mechanism 300.

As shown in fig. 7, the carrying platform 220 is further provided with a bottom hole detecting device 230, a control device (not shown in the figure), and an active wire feeding device 240. Wherein, the bottom hole detection device 230 can automatically detect the position of the bottom hole 804 of the wire coil 800 on the automatic winding mechanism 300; the control device can control the bearing platform 220 to drive the wire feeding nozzle 210 to move when the bottom hole detection device 230 detects the position of the bottom hole 804, so that the wire feeding direction of the wire feeding nozzle 210 faces the bottom hole 804; the active wire feeding device 240 is used to provide an active feeding force to the wire during threading to feed the front end of the wire into the bottom hole 804 of the wire spool 800.

The bottom hole detecting device 230 may be implemented in various ways, for example, a reflective photoelectric sensor generally includes a transmitter and a receiver, and the principle of operation of the reflective photoelectric sensor is to emit detection light by the transmitter and receive the detection light reflected by the object by the receiver, and analyze the state of the reflected detection light to determine the state of the object. The reflective photoelectric sensor has the advantages of simple structure, convenient use and high detection precision. Specifically, the reflective photoelectric sensor may include an infrared reflective photoelectric sensor, a laser reflective photoelectric sensor, an ultrasonic reflective photoelectric sensor, or the like.

When the reflective photoelectric sensor is adopted, the light emitting direction of the reflective photoelectric sensor can be set towards the wire coil 800 on the automatic wire winding mechanism 300, after the reflective photoelectric sensor is opened, the emitter in the reflective photoelectric sensor can emit detection light towards the wire coil 800, in the process of rotating the wire coil 800, when the detection light irradiates the wire winding roller 801 of the wire coil, the detection light is reflected by the wire winding roller 801, and is received by the receiver in the reflective photoelectric sensor, and if the receiver continuously receives a reflected light signal, the bottom hole is not detected. When the detection light passes through the bottom hole 804, the detection light is emitted from the bottom hole, the receiver in the reflective photoelectric sensor cannot receive the reflected light signal, and the control device determines that the bottom hole detection device 230 detects the position of the bottom hole 804. The control device may then control the automatic winding mechanism 300 to stop rotating, and the wire coil 800 is stopped at the current position. Since the relative positions of the wire feeding nozzle 210 and the reflective photoelectric sensor can be preset, the wire feeding nozzle 210 is controlled to move to the position of the reflective photoelectric sensor, so that the wire feeding direction of the wire feeding nozzle 210 can be aligned with the bottom hole 804.

As shown in fig. 9, the reflective photoelectric sensor may be disposed at a first preset position, the wire feeding nozzle 210 may be disposed at a second preset position, and the light emitting direction of the detection light L of the reflective photoelectric sensor may be parallel to the wire feeding direction of the wire feeding nozzle 210. In addition, since the automatic feeding and discharging mechanism 100 is configured to mount the wire coil 800 on the automatic winding mechanism 300 in a preset posture, the position of the bottom hole 804 on each wire coil 800 in the axial direction of the wire coil 800 is fixed, and when the initial position (i.e., the first preset position) of the reflective photoelectric sensor is set, the position of the bottom hole 804 in the axial direction of the wire coil 800 may be set to correspond to the position of the detection light irradiated on the wire coil 800, that is, the position of the bottom hole 804 on the track along with the rotation of the wire coil 800. Thus, when the detection light does not pass through the bottom hole 804, the control device controls the automatic winding mechanism 300 to drive the wire coil 800 to rotate continuously; until the detection light passes through the bottom hole 804, the control device controls the automatic winding mechanism 300 to stop rotating, and controls the carrying platform 220 to drive the wire feeding nozzle 210 to move from the second preset position to the first preset position, so that the wire feeding direction of the wire feeding nozzle 210 faces the bottom hole 804. Since the light emitting direction of the reflective photoelectric sensor is parallel to the wire feeding direction of the wire feeding nozzle 210, the carrying platform 220 drives the wire feeding nozzle 210 to translate to the first preset position.

The bottom hole detecting device 230 and the wire feeding nozzle 210 may be separately installed or may be installed together, and when the bottom hole detecting device 230 and the wire feeding nozzle 210 may be separately installed, the bottom hole detecting device 230 and the wire feeding nozzle 210 may be separately installed on the carrier 220, respectively.

After the wire feeder 210 is aligned with the bottom hole 804 of the wire coil 800 of the automatic winding mechanism 300, the active wire feeder 240 provides an active conveying force to the wire to feed the front end of the wire into the bottom hole 804 of the wire coil 800. As shown in fig. 10, the active wire feeding device 240 includes a driving wheel 241, a first pinch wheel 242, a driving wheel driving member 243, and a first pinch wheel 242 driving member (not shown in the drawings). Wherein the driving wheel 241 is fixed relative to the bearing table 220; the first compression wheel 242 is disposed opposite to the driving wheel 241 in the vertical direction, and is movable in the vertical direction relative to the driving wheel 241; the driving wheel driving member 243 is used for driving the driving wheel 241 to rotate. The wire rod passes through the space between the first pressing wheel 242 and the driving wheel 241, and the first pressing wheel 242 is driven by the driving piece of the first pressing wheel 242 to move downwards so as to press the wire rod. The driving wheel driving piece 243 drives the driving wheel 241 to rotate, so that the friction force between the first compressing wheel 242 and the driving wheel 241 can drive the wire to be conveyed forwards, and the front end of the wire can penetrate into the bottom hole 804. In order to increase the friction between the driving wheel 241 and the wire, the surface of the driving wheel 241 may be provided with anti-slip patterns, which may be in a grid or wire structure, so that the conveying force provided by the driving wheel 241 to the wire is more stable and the slipping during wire feeding is prevented.

When the output shaft of the driving wheel driving member 243 is different from the rotating shaft of the driving wheel 241 in size, the output shaft and the rotating shaft may be connected by a coupling.

The driving member of the first pressing wheel 242 may be implemented by an air cylinder, and of course, may be implemented by other linear driving devices.

It should be noted that, the active wire feeding device 240 only needs to provide an active conveying force for the wire when the wire penetrates into the bottom hole 804 of the empty wire coil, and when the wire enters into the bottom hole 804 of the wire coil 800, the automatic wire winding mechanism 300 may drive the empty wire coil to rotate, so that the active conveying force is provided for the wire by the automatic wire winding mechanism 300, and at this time, the active wire feeding device 240 may be turned off.

After the front end of the wire rod penetrates into the bottom hole 804, in order to prevent the wire rod from being pulled out of the bottom hole 804, the front end of the wire rod penetrating into the bottom hole 804 may be pressed by the automatic winding mechanism 300. As shown in fig. 12 and 13, the automatic winding mechanism 300 includes a fixed base 310, a driving shaft 320, a driving shaft driving member 330 and a wire pressing device, wherein the fixed base 310 is fixedly arranged on the stand 700, the driving shaft 320 is arranged on the fixed base 310, the driving shaft driving member 330 is used for driving the driving shaft 320 to rotate, and the wire pressing device is arranged opposite to the driving shaft 320. When the automatic feeding and discharging mechanism 100 installs the wire coil 800 on the automatic winding mechanism 300, the first end of the central hole 803 of the wire coil 800 is sleeved on the driving shaft 320, then the wire coil 800 is loosened by the automatic feeding and discharging mechanism 100, and the wire pressing device stretches into the wire coil 800 from the second end of the central hole 803 so as to press the wire rod penetrating into the bottom hole 804 of the wire coil 800.

As shown in fig. 12 and 15, the wire pressing device includes a moving base 340 disposed opposite to the fixed base 310, the moving base 340 is capable of moving along the axial direction of the driving shaft 320, an auxiliary shaft 350 is disposed on the moving base 340, and the auxiliary shaft 350 is disposed coaxially with the driving shaft 320.

The auxiliary shaft 350 is connected to an auxiliary shaft moving assembly 360, and the auxiliary shaft moving assembly 360 can drive the auxiliary shaft 350 to move along the axial direction of the driving shaft 320, so that the auxiliary shaft 350 extends into or out of the second end of the central hole 803. As shown in fig. 15 and 16, the auxiliary shaft 350 has an axial through hole, the wire pressing shaft 370 is inserted into the axial through hole of the auxiliary shaft 350 and can slide axially relative to the auxiliary shaft 350, the wire pressing shaft 370 is connected with a wire pressing shaft driving assembly 380, and the wire pressing shaft 370 can be driven to slide axially along the auxiliary shaft 350 by the wire pressing shaft driving assembly 380 so as to extend or retract the auxiliary shaft 350, and when the wire pressing shaft 370 extends out of the auxiliary shaft 350, the wire pressing shaft 370 compresses the wire penetrating into the bottom hole 804. The wire pressing shaft 370 may press the wire against the driving shaft 320 when pressing the wire.

The auxiliary shaft moving assembly 360 can be implemented in various ways, as long as it can drive the auxiliary shaft 350 to move along a straight line. For example, as shown in fig. 15, the auxiliary shaft moving assembly 360 includes an auxiliary shaft rail 361, and a screw nut assembly for driving the moving base 340 to slide along the auxiliary shaft rail 361. The auxiliary shaft guide rail 361 is disposed along an axial direction of the driving shaft 320, the moving base 340 is slidably connected with the auxiliary shaft guide rail 361, the screw nut assembly includes an auxiliary shaft screw 362, an auxiliary shaft 350 nut (not shown in the drawing) and an auxiliary shaft motor 363, the auxiliary shaft screw 362 is disposed parallel to the auxiliary shaft guide rail 361, the auxiliary shaft 350 nut is fixed on the moving base 340 and is in threaded engagement with the auxiliary shaft screw 362, and the auxiliary shaft motor 363 is in transmission connection with the auxiliary shaft screw 362 to drive the auxiliary shaft screw 362 to rotate. It should be noted that, the screw nut assembly is only one possible implementation manner of the auxiliary shaft moving assembly 360, and the auxiliary shaft moving assembly 360 may also be implemented by a rack and pinion assembly, a linear cylinder, a linear motor, or the like. In addition, the auxiliary shaft motor 363 and the auxiliary shaft screw 362 may be connected in a driving manner, for example, the auxiliary shaft motor 363 and the auxiliary shaft screw 362 may be directly connected, or may be indirectly connected through other driving components, the driving components may adopt a driving manner such as gear driving and chain driving, the structure shown in fig. 15 adopts a belt driving manner such as a belt pulley and a belt, and the output shaft of the motor is parallel to the screw and is arranged along the up-down direction, so that the transverse arrangement space may be saved.

The above-mentioned crimping shaft driving assembly 380 can be implemented in various ways, as long as the crimping shaft 370 can be driven to stretch and retract relative to the auxiliary shaft 350. In one implementation, as shown in fig. 17 and 18, the pressing shaft driving assembly 380 includes a pressing cylinder 381, and a piston rod of the pressing cylinder 381 is connected to the pressing shaft 370 to drive the pressing shaft 370 to slide along an axial direction of the auxiliary shaft 350. In order to maintain the crimp shaft 370 in the retracted state when the crimp shaft 370 is not crimped, a restoring member 382 may be further provided, the restoring member 382 being coupled to the crimp shaft 370 so as to apply a restoring force to the crimp shaft 370 maintained in the retracted state. Specifically, the reset element 382 may be implemented by using an elastic element such as a spring or a shrapnel.

When the reset member 382 adopts a spring, as shown in fig. 17, a spring accommodating cavity is disposed between the auxiliary shaft 350 and the wire pressing shaft 370, a first positioning portion 383 is disposed on the outer wall of the wire pressing shaft 370, a second positioning portion 384 is disposed on the inner wall of the auxiliary shaft 350, the second positioning portion 384 is disposed on the outer side of the first positioning portion 383 (i.e., on the side close to the driving shaft 320), the spring accommodating cavity is disposed between the first positioning portion 383 and the second positioning portion 384, the spring is disposed in the spring accommodating cavity, one end of the spring abuts against the first positioning portion 383, and the other end of the spring abuts against the second positioning portion 384. The spring is maintained in a compressed state all the time, and the return force of the spring maintains the spool 370 in a retracted state. So that the pressing bobbin 370 is prevented from being protruded out of the auxiliary shaft 350 or from falling out of the axial through hole of the auxiliary shaft 350 when the pressing is not performed.

To guide the telescopic movement of the pressing shaft 370, as shown in fig. 18, the pressing shaft driving assembly 380 further includes a pressing shaft guide 385 and a pressing shaft sliding support 386, wherein the pressing shaft guide 385 is disposed on the moving base 340 and extends along the axial direction of the driving shaft 320, and the pressing shaft sliding support 386 is slidably engaged with the pressing shaft guide 385 and connected with the piston rod of the pressing cylinder 381. The spool 370 is disposed on the spool sliding support 386. Thus, the spool 370 can be precisely guided by the spool guide rail 385 and the spool sliding bracket 386, thereby making the movement of the spool 370 smoother.

Because the wire rod volume is less, in order to increase the line ball area, prevent to press and not reach the end of a thread, as shown in fig. 17, still can set up line ball piece 371 in line ball axle 370's outer end, line ball piece 371's external diameter is greater than the external diameter of line ball axle 370, from this, can increase the line ball area, ensure the success rate of line ball. In addition, the material of the pressing block 371 may be an elastic material such as rubber, nylon, etc., to prevent damage to the wire during the pressing process.

When the front end of the wire rod penetrates into the bottom hole 804 and is pressed by the pressing shaft 370, step S3 is started, and the driving shaft 320 of the automatic winding mechanism 300 drives the wire coil 800 to rotate so as to wind the wire rod.

The driving shaft driving member 330 may be implemented in various ways as long as the driving shaft 320 can be driven to rotate, for example, the driving shaft driving member 330 may include a driving shaft 320 driving motor and a transmission assembly, and the driving shaft 320 driving motor drives the driving shaft 320 to rotate through the transmission assembly. The drive assembly may be implemented in a variety of ways, for example, belt drive assemblies, chain drive assemblies, gear drive assemblies, etc. may alternatively be employed. The gear transmission assembly can adopt a cylindrical gear set or a bevel gear set, and the bevel gear is a bevel gear, in particular a straight bevel gear or a spiral bevel gear. The bevel gear set can be used for transmitting power between two intersecting shafts, so that the axial arrangement space can be saved. In the solution shown in fig. 13, the driving shaft 320 is driven by a motor arranged in a vertical direction, and the output shaft of the driving shaft 320 is perpendicular to the driving shaft 320. The bevel gear set comprises a first bevel gear and a second bevel gear which are meshed with each other, the first bevel gear is fixedly connected with the output shaft, and the second bevel gear is fixedly connected with the driving shaft 320, so that power transmission between the output shaft and the driving shaft 320 is realized, and the axial arrangement space is saved.

There are various implementations of rotating the wire coil 800 with the driving shaft 320, for example, a transmission structure similar to a key transmission may be provided between the wire coil 800 and the driving shaft 320 or between the wire coil 800 and the first pressing portion 321, so that the wire coil 800 can rotate synchronously with the driving shaft 320. In addition, the structure shown in fig. 13 and 15 may be adopted, the driving shaft 320 is provided with a first pressing portion 321, the auxiliary shaft 350 is provided with a second pressing portion 351, and when the wire coil 800 needs to be mounted on the driving shaft 320, the wire pressing device may be moved in a direction away from the driving shaft 320, so as to reserve a sufficient operation space for mounting the wire coil 800. When the wire coil 800 is sleeved on the driving shaft 320, the first pressing portion 321 abuts against the first end face of the wire coil 800, and at this time, the auxiliary shaft 350 can be driven by the auxiliary shaft moving assembly 360 to move towards the direction close to the driving shaft 320, the second pressing portion 351 gradually approaches to the first pressing portion 321 and finally abuts against the second end face of the wire coil 800, so that the first pressing portion 321 and the second pressing portion 351 clamp the wire coil 800 along the axial direction of the wire coil 800. The driving shaft driving member 330 is then activated such that the driving shaft driving member 330 rotates the driving shaft 320 to wind the wire around the wire coil 800. The first end surface and the second end surface of the wire coil 800 are two end surfaces arranged along the axial direction of the wire coil 800, that is, the outer surfaces of the limit baffles 802 at the two ends of the wire coil 800 in fig. 4.

It should be noted that, the bottom hole 804 of the wire coil 800 may be located away from the driving shaft 320, so as to avoid the wire being blocked by the bottom hole 804 during threading. Since the winding is started from one end of the winding roller 801 at the time of winding, the length of the driving shaft 320 may be set short in order to avoid the bottom hole 804. However, when the first end of the central hole 803 of the wire coil 800 is sleeved on the driving shaft 320, the automatic feeding and discharging mechanism 100 loosens the wire coil 800, and at this time, since the driving shaft 320 is relatively short, only a part of the central hole 803 of the wire coil 800 is sleeved on the driving shaft 320, so that there is a risk of falling off. To solve the above problem, a wire coil clamping assembly 390 may be provided at one side of the driving shaft 320, and the wire coil clamping assembly 390 is configured to clamp the wire coil 800 fitted around the driving shaft 320 to the first compressing part 321. Accordingly, the wire coil 800 can be temporarily fixed before the second pressing portion 351 clamps the wire coil 800, thereby preventing the wire coil 800 from falling off the driving shaft 320. When the first compressing part 321 and the second compressing part 351 simultaneously compress the disc before the disc, the disc clamping assembly 390 releases the disc 800.

As shown in fig. 13, the wire coil clamping assembly 390 includes a wire coil clamping jaw 391 and a clamping cylinder 392, wherein one end of the clamping cylinder 392 away from the wire coil clamping jaw 391 is hinged with the fixed base 310, and the wire coil clamping jaw 391 is disposed on the fixed base 310 and located at one side of the first pressing part 321; a clamping cylinder 392 is coupled to the wire coil clamping jaw 391 and is configured to open and close the wire coil clamping jaw 391 to clamp or unclamp the wire coil 800. As shown in fig. 13, wire coil clamping jaw 391 may include a first hinge portion 3911, a second hinge portion 3912, and a clamp portion 3913. The first hinge part 3911 is hinged with the fixed base 310; the second hinge part 3912 is hinged with a piston rod of the clamping cylinder 392; the clamping portion 3913 is configured to contact the wire coil 800 to clamp the wire coil 800. When the piston rod of the clamping cylinder 392 extends, the piston rod drives the clamping portion 3913 to rotate around the first hinge portion 3911 in a direction approaching the wire coil 800 so as to clamp the wire coil 800; when the piston rod of the clamping cylinder 392 is retracted, the piston rod drives the clamping portion 3913 to rotate about the first hinge portion 3911 in a direction away from the wire coil 800 to unwind the wire coil 800.

In the process of the automatic winding mechanism 300 driving the wire coil 800 to rotate and wind, the automatic winding mechanism 200 can be used for winding. The main function of the automatic wire arranging mechanism 200 is to guide the wire to change the winding position of the wire on the winding roller 801, so that the wire is more uniformly arranged on the winding roller 801 of the whole wire coil 800.

In the winding process, the automatic wire arranging mechanism 200 drives the wire feeding nozzle 210 to move for wire arrangement. In order to uniformly wind the wire on the winding roller 801 of the wire coil 800 during wire arrangement, the wire can be arranged along the axial direction of the winding roller 801, so that one function of the carrying platform 220 is to drive the wire feeding nozzle 210 to move along the first horizontal direction (i.e. the axial direction of the wire coil 800 on the automatic winding mechanism 300), so as to realize uniform wire arrangement of the wire on the winding roller 801 along the axial direction.

In addition, since the wire rod includes a soft material, a certain tension is applied to the wire rod when the wire rod is wound after extrusion molding, so that the wire rod is maintained at a certain amount of tension, but if the tension is too large, the wire rod is easily subjected to tension deformation, so that the cross-sectional area of the wire rod is reduced, thereby affecting the quality of the wire rod. When the wire is wound on the wire coil 800, the tension of the wire is continuously increased as the number of winding layers of the wire is continuously increased because the relative position of the wire feeding nozzle 210 and the wire coil 800 is kept unchanged. When the cross-sectional area of the wire rod is smaller than the standard value required by products after the cross-sectional area is increased to a certain extent, the wire rod is possibly broken. In order to avoid the above problems, the distance between the wire feeding nozzle 210 and the wire coil 800 can be adjusted in real time according to the change of the number of winding layers of the wire on the wire coil 800, so that the tension of the wire is kept unchanged. Therefore, the other function of the moving base 340 is to drive the wire feeding nozzle 210 to move along the second horizontal direction (the horizontal direction perpendicular to the axial direction of the wire coil 800) so as to adjust the distance between the wire feeding nozzle 210 and the wire coil 800, and drive the wire feeding nozzle 210 to move along the vertical direction so as to adjust the height of the wire feeding nozzle 210 relative to the wire coil 800, so that the relative position of the wire feeding nozzle 210 and the wire coil 800 can be adjusted from two dimensions so as to adapt to the change of the winding layer number of the wire on the wire coil 800, and the tension of the wire is kept within the preset range. For example, in the winding process, along with the increase of the number of winding layers of the wire, the bearing table driving device drives the bearing table to move in the direction away from the wire coil, so that the length of the wire between the wire feeding nozzle and the wire coil can be kept within a preset range all the time, the tension of the wire can be prevented from being increased continuously, and the tension of the wire is kept within the preset range in the winding process.

The length of the wire between the wire feeding nozzle and the wire coil refers to the length of the wire after the wire outlet end of the wire feeding nozzle and before the wire is wound on the winding roller. The distance that the bearing table driving device drives the bearing table to move towards the direction away from the wire coil can be preset according to the number of winding layers of the wire rod on the wire coil, for example, if each layer of winding layers is increased, the bearing table correspondingly moves towards the direction away from the wire coil for a certain distance.

In addition, in addition to adjusting the distance between the wire feeding mouth and the wire coil, the tension of the wire can be maintained by adjusting the position of the wire feeding mouth in the vertical direction. For example, if the tangent point of the wire with the wire winding roller is located at the upper edge of the wire winding roller, moving the wire feeding nozzle upward can increase the length of the wire between the wire feeding nozzle and the wire coil, so that the tension of the wire can be reduced; conversely, if the tangent point of the wire and the winding roller is located at the lower edge of the winding roller, moving the wire feeding nozzle downward can increase the length of the wire between the wire feeding nozzle and the wire coil, and the tension of the wire can be reduced as well.

In order to achieve the above-described movement of the stage 220, as shown in fig. 7 and 9, the stage driving device includes an X-axis moving assembly 250, a Y-axis moving assembly 260, and a Z-axis moving assembly 270. The X-axis moving assembly 250 is configured to move the carrying table 220 along a first horizontal direction (i.e. an axial direction of the wire coil 800 on the automatic winding mechanism 300) so as to adjust a position of the wire feeding nozzle 210 along the axial direction of the wire coil 800. For example, in the wire arranging process, the X-axis moving assembly 250 drives the carrying platform 220 to reciprocate along the first horizontal direction, so that the wire can be wound and rewound in multiple layers on the winding roller of the wire coil. And the limit sensor can be further arranged to control the range of the X-axis moving assembly 250 to drive the bearing table 220 to move along the first horizontal direction, so that the range is adapted to the length of the winding roller of the wire coil. When the above-mentioned limit sensor has a counting function, the number of times that the carrying platform 220 reciprocates along the first horizontal direction can also be detected by the above-mentioned limit sensor, so as to calculate the number of winding layers of the wire on the wire coil, so as to control the distance between the wire feeding nozzle 210 and the wire coil.

The Y-axis moving assembly 260 is configured to drive the carrying platform 220 to move along a second horizontal direction, which is perpendicular to the first horizontal direction, to adjust the distance between the wire feeding nozzle 210 and the wire coil 800. Therefore, the distance between the wire feeding nozzle 210 and the wire coil can be adjusted in real time, so that the tension of the wire is kept within a preset range in the winding process.

The Z-axis moving assembly 270 is configured to move the carrying table 220 in a vertical direction to adjust the height of the wire feeder 210 with respect to the wire coil 800. Thereby, the tension of the wire can be maintained by adjusting the position of the wire mouth in the vertical direction.

Simultaneously, the X-axis moving assembly 250, the Y-axis moving assembly 260 and the Z-axis moving assembly 270 are arranged, so that the wire feeding nozzle 210 can move in the directions X, Y, Z, and the wire can be uniformly arranged on the winding roller 801 along the radial direction, and the tension of the wire is kept unchanged in the wire arranging process.

When the relative positional relationship of the bearing table 220, the X-axis moving assembly 250, the Y-axis moving assembly 260, and the Z-axis moving assembly 270 is specifically set, the X-axis moving assembly 250 may be connected to the bearing table 220, so as to drive the bearing table 220 to move along the first horizontal direction; connecting the Z-axis moving assembly 270 with the X-axis moving assembly 250 to drive the X-axis moving assembly 250 and the carrier 220 to lift; the Y-axis moving assembly 260 is connected to the Z-axis moving assembly 270 to drive the Z-axis moving assembly 270, the X-axis moving assembly 250, and the stage 220 to move along the second horizontal direction. Whereby the movement of the wire feeder 210 in the three directions X, Y, Z can be achieved. It should be noted that, in addition to the above embodiments, the driving relationships of the X-axis moving assembly 250, the Y-axis moving assembly 260, and the Z-axis moving assembly 270 may be arbitrarily arranged and combined, for example, the Y-axis moving assembly 260 may be directly connected to the carrier 220, the X-axis moving assembly 250 may be connected to the Y-axis moving assembly 260, and the Z-axis moving assembly 270 may be connected to the X-axis moving assembly 250. For another example, the Z-axis moving assembly 270 may be directly connected to the stage 220, the X-axis moving assembly 250 may be connected to the Z-axis moving assembly 270, and the Y-axis moving assembly 260 may be connected to the X-axis moving assembly 250.

The X-axis moving assembly 250, the Y-axis moving assembly 260, and the Z-axis moving assembly 270 may be implemented in various manners, as long as the linear driving can be implemented, for example, a cylinder driving, a linear motor driving, a motor-matching gear-rack driving, a motor-matching screw-nut driving, a linear module driving, and the like may be adopted. The linear module is also called a linear module, a linear sliding table and the like, and is an automatic upgrading unit for the linear guide rail, the linear motion module and the ball screw linear transmission mechanism.

In order to smoothly introduce the wire produced on the production line into the wire feeding nozzle 210, a wire guiding assembly 280 may be further disposed on the carrying platform 220, and the wire guiding assembly 280 may guide the wire into the wire feeding nozzle 210 along the extending direction of the wire feeding nozzle 210, so as to avoid bending when the wire enters the wire feeding nozzle 210.

As shown in fig. 9, the wire guide assembly 280 may include a first guide assembly 281 and a second guide assembly 282 sequentially disposed along the second horizontal direction. Wherein the first guide assembly 281 is configured to limit the position of the wire in the first horizontal direction so that the wire is aligned with the wire nozzle 210 in the first horizontal direction. A second guide assembly 282 is disposed downstream of the first guide assembly 281 and is configured to limit the position of the wire in the vertical direction so that the wire is aligned with the wire nozzle 210 in the vertical direction. Thereby, the position of the wire may be restricted in the first horizontal direction and the vertical direction to align the feeding direction of the wire with the inlet of the wire feeding nozzle 210, preventing the wire from being bent when entering the wire feeding nozzle 210.

Wherein, the specific structure of the first guide assembly 281 may be as shown in fig. 9, the first guide assembly 281 includes a first guide roller 2811 and a second guide roller 2812, the first guide roller 2811 and the second guide roller 2812 may be disposed along the vertical direction, and the first guide roller 2811 and the second guide roller 2812 may be arranged at intervals along the first horizontal direction, and a wire may pass between the first guide roller 2811 and the second guide roller 2812, thereby limiting the position of the wire in the first horizontal direction. When first guide roller 2811 and second guide roller 2812 are provided, the gap between first guide roller 2811 and second guide roller 2812 can be aligned with the entrance of wire feeder nozzle 210, thereby enabling alignment of the wire with wire feeder nozzle 210 in the first horizontal direction.

The specific structure of the second guide assembly 282 may be as shown in fig. 11, and the second guide assembly 282 includes an upper guide wheel set 2821 and a lower guide wheel set 2822, wherein the upper guide wheel set 2821 includes a plurality of upper guide wheels, and the plurality of upper guide wheels are arranged along the second horizontal direction. The lower guiding wheel set 2822 is disposed below the upper guiding wheel set 2821, the lower guiding wheel set 2822 includes a plurality of lower guiding wheels, and the plurality of lower guiding wheels are arranged along the second horizontal direction. The wire passing through the first guide assembly 281 may pass between the upper and lower guide wheel sets 2821 and 2822, so that the position of the wire in the vertical direction may be restricted. When the upper and lower guide wheel sets 2821 and 2822 are provided, a gap between the upper and lower guide wheel sets 2821 and 2822 may be aligned with an inlet of the wire feeding nozzle 210, so that alignment of the wire with the wire feeding nozzle 210 in the vertical direction may be achieved.

When the relative positions of the upper guide wheels and the lower guide wheels are set, the upper guide wheels and the lower guide wheels may be vertically staggered so that the upper guide wheels and the lower guide wheels can be in sufficient contact with the wire. Namely, the upper guide wheel and the lower guide wheel are not aligned in the vertical direction, and the projection of the upper guide wheel on the plane of the lower guide wheel is positioned between the two adjacent lower guide wheels. Therefore, when the wire rod passes through the space between the upper guide wheel set 2821 and the lower guide wheel set 2822, the wire rod, the upper guide wheel and the lower guide wheel can have larger contact area, so that the whole stress of the wire rod in the transmission process is more uniform.

To accommodate wires of different diameters, one of the upper and lower guide wheel sets 2821, 2822 may be provided in a movable structure. For example, the lower guide wheel set 2822 may be fixed relative to the carrier 220, and the upper guide wheel set 2821 may be movable in the vertical direction relative to the carrier 220. Therefore, when threading is initially performed, the upper guide wheel set 2821 can be lifted upwards, and after the wire rod passes through between the upper guide wheel set 2821 and the lower guide wheel set 2822, the upper guide wheel set 2821 is put down to press the wire rod. Thus, wires with different diameters can be allowed to pass through between the upper guide wheel set 2821 and the lower guide wheel set 2822, and the universality of the equipment is improved. In addition, the upper guide wheel set 2821 may be fixed relative to the carrying table 220, and the lower guide wheel set 2822 may be movable in the vertical direction relative to the carrying table 220. Or the upper guide wheel set 2821 and the lower guide wheel set 2822 are arranged to be movable in the vertical direction relative to the bearing table 220.

As shown in fig. 11, a guide wheel fixing frame 2823 and a guide wheel moving frame 2824 may be disposed on the bearing table 220, wherein the guide wheel fixing frame 2823 is fixed with respect to the bearing table 220, and the lower guide wheel set 2822 is fixedly disposed on the guide wheel fixing frame 2823; the guide wheel moving frame 2824 is movably disposed on the guide wheel fixing frame 2823 and located above the lower guide wheel set 2822, the guide wheel moving frame 2824 can move in a vertical direction relative to the guide wheel fixing frame 2823, and the upper guide wheel set 2821 is disposed on the guide wheel moving frame 2824. The guide wheel moving frame 2824 is also connected with a moving frame driving member, and the moving frame driving member is used for driving the guide wheel moving frame 2824 to move along the vertical direction.

The driving part of the movable frame has various implementation schemes, such as cylinder driving, linear motor driving, motor matched with gear rack driving, motor matched with screw nut driving and the like. In the solution shown in fig. 11, a cylinder driving is adopted, and the moving frame driving member includes a moving frame rail 2825 and a moving frame driving cylinder 2826, where the moving frame rail 2825 is disposed on the guide wheel fixing frame 2823 in a vertical direction and is in sliding fit with the guide wheel moving frame 2824; the moving frame driving cylinder 2826 is connected with the guide wheel moving frame 2824 to drive the guide wheel moving frame 2824 to move in the vertical direction. The number of components driven by the air cylinder is small, the assembly is easy, and the space is saved.

In order to precisely adjust the conveying direction of the wire, at least one lower guide wheel of the lower guide wheel set 2822 and the guide wheel fixing frame 2823 can be connected through an adjustable structure, so that the position of the lower guide wheel in the vertical direction can be adjusted. For example, the lower guide wheels of the lower guide wheel set 2822 at both ends may be connected to the guide wheel mount 2823 by the adjustable structure. Thus, the conveying direction of the wire can be accurately adjusted. Specifically, the adjustable structure include set up in guide way on the leading wheel mount 2823, set up in slider and the fastener on the lower leading wheel, wherein, slider and guide way sliding fit, the fastener can be in locking state and unlocking state between switch, when the fastener is in locking state, the fastener will lower leading wheel with the guide way locking is fixed, when the fastener is located unlocking state, lower leading wheel can be for the guide way slip. Specifically, the fastener may be implemented by a screw, a pin, or the like.

In order to be able to count the winding length of the wire during the winding process of the wire, a metering assembly 290 may be provided. The metering assembly 290 is capable of metering the length of wire wound onto the spool 800 to facilitate accurate statistics of wire produced by the production line.

As shown in fig. 11, the metering assembly 290 may specifically include a metering roller 291, a second pressing wheel 292, and a rotation detecting member (not shown), wherein the metering roller 291 is disposed on a conveying path of the wire; the second pressing wheel 292 is disposed opposite to the metering roller 291 in the vertical direction, and is movable along the vertical direction with respect to the metering roller 291, and the rotation detecting member is connected to the metering roller 291 to detect the number of rotations of the metering roller 291. The wire can be passed between the metering roller 291 and the second pressing roller 292, and when the metering roller 291 and the second pressing roller 292 press the wire, the forward-conveying friction force of the wire can drive the metering roller 291 to rotate, and the length of the wire passing through the metering roller 291 can be calculated by the number of turns of the metering roller 291 detected by the rotation detecting member because the metering roller 291 is connected with the rotation detecting member. Wherein, the rotation detecting piece can adopt a detecting instrument such as a rotary encoder.

To achieve the up and down movement of the second clamp wheel 292, a separate driving member may be used to drive the second clamp wheel 292, for example, a separate cylinder may be used to drive it up and down. In addition, as shown in fig. 11, the second pressing wheel 292 and the upper guide wheel set 2821 may be disposed together, for example, on the guide wheel moving frame 2824, so that the second pressing wheel 292 and the upper guide wheel set 2821 are driven by the moving frame driving member, thereby reducing the number of driving members, saving the equipment cost and reducing the occupied space. In a specific arrangement, the metering roller 291 may be disposed on the guide roller mount 2823 and aligned with the plurality of lower guide rollers along the second horizontal direction, and the second pressing roller 292 may be disposed on the guide roller moving mount 2824 and aligned with the plurality of upper guide rollers along the second horizontal direction.

After the winding of the wire on the wire coil 800 is completed, step S4 may be performed, i.e., the wire is cut and fixed to the wire coil 800, so as to complete the tail wire winding process. The term "tail" as used herein is understood to mean the tail end of the wire wound on the wire coil 800. After the winding of the wire is completed, the tail end of the wire needs to be fixed or knotted with the wire coil 800 to prevent the wire wound on the wire coil 800 from being loosened. The ending line means to tie the tail line, i.e. the process of fixing or tying the tail end of the wire to the wire coil 800.

The above-described wire bonding process may be implemented by an automatic wire bonding mechanism 400. As shown in fig. 19 and 20, the automatic tail-wire winding mechanism 400 may be disposed on the automatic wire winding mechanism 300, and the automatic tail-wire winding mechanism 400 includes a wire cutting module 410 and a wire threading module. The wire cutting module 410 is configured to automatically cut off an end of the wire that is not wound on the wire coil 800 after the wire is wound on the wire coil 800, so as to form a tail end of the wire. The threading module is used for automatically penetrating the tail end of the wire rod into the threading hole of the wire coil 800 and fixing the wire rod.

The automatic tail-wire winding mechanism 400 is disposed on the automatic winding mechanism 300, and includes the automatic tail-wire winding mechanism 400 being directly mounted on the automatic winding mechanism 300, and also includes the automatic tail-wire winding mechanism 400 being located near the automatic winding mechanism 300 but not directly mounted on the automatic winding mechanism 300.

The wire cutting module 410 may include automatic scissors and a scissors drive. Wherein, the automatic scissors can be automatically opened and closed to cut the wire; the scissors driving device can drive the automatic scissors to move to a wire cutting position. Specifically, the automatic scissors may be pneumatic scissors or electric scissors.

In order to fix the tail end of the wire with the wire coil 800 more firmly, two threading holes, namely a first threading hole 805 and a second threading hole 806, are generally arranged on the wire coil 800, and the tail end of the wire is sequentially threaded through the first threading hole 805 and the second threading hole 806 and is tensioned, so that the relative fixation of the wire and the wire coil 800 can be completed. As shown in fig. 20, the first threading hole 805 and the second threading hole 806 may be disposed on the same side of the wire coil 800, and at this time, the tail end of the wire may be threaded through the first threading hole 805 first, and then threaded through the second threading hole 806 after the tail end of the wire is turned to the direction, so as to fix the wire relative to the wire coil 800. To accomplish this, the threading module includes a thread feeding module 420 and a thread guide mechanism 430. The wire feeding module 420 may automatically penetrate the tail end of the wire into the first threading hole 805 of the wire coil 800. And the thread guide mechanism 430 is configured to guide the tail end to be passed out of the second thread hole 806 after the tail end is passed through the first thread hole 805.

The automatic tail wire winding mechanism 400 is provided with the wire guiding mechanism 430, and the wire guiding mechanism 430 can guide the tail end to be pulled out of the second threading hole 806 after the tail end passes through the first threading hole 805, so that the wire feeding module 420 only needs to continuously feed wire into the first threading hole 805 when threading, and the wire can finish turning in the direction under the action of the wire guiding mechanism 430 after entering the first threading hole 805, and gradually passes out of the second threading hole 806 along with continuous wire feeding of the wire feeding module 420. Therefore, the wire and the wire coil 800 can be fixed without the complicated threading operation of the wire feeding module 420, and the implementation is more convenient.

The wire guide mechanism 430 may include a wire guide assembly and a wire guide driver (not shown). As shown in fig. 20, the wire groove assembly includes a base plate 431 and a wire groove 432 disposed on a first surface of the base plate 431, wherein a first end of the wire groove 432 faces the first threading hole 805, and a second end of the wire groove 432 faces the second threading hole 806. Therefore, after the tail end of the wire rod passes through the first threading hole 805, the wire rod can enter the wire guide groove 432 from the first end of the wire guide groove 432, and the wire rod can bend and turn under the guidance of the wire guide groove 432 by virtue of the flexibility of the wire rod, and gradually passes out from the second end of the wire guide groove 432 and passes through the second threading hole 806.

It should be noted that, the first end of the wire groove 432 faces the first threading hole 805, and the first end of the wire groove 432 may be directly attached to and connected with the first threading hole 805, or the first end of the wire groove 432 may be opposite to the first threading hole 805 with a certain gap. Similarly, the second end of the wire groove 432 faces the second threading hole 806, which may be that the second end of the wire groove 432 is directly attached to and connected with the second threading hole 806, or that the second end of the wire groove 432 is opposite to the second threading hole 806 with a certain gap.

The above-mentioned wire groove driving member is used for driving the wire groove assembly to move towards the direction close to or far away from the wire coil 80011, therefore, when the wire winding process is required, the wire groove driving member can move the wire groove assembly towards the direction close to the wire coil 800, so that the two ends of the wire groove assembly are respectively communicated with the first threading hole 805 and the second threading hole 806. When the wire ending process is finished, the wire groove driving member can move the wire groove assembly away from the wire coil 800, so that the wire groove assembly is separated from the wire, and the wire coil 800 which is wound is taken down conveniently.

It should be noted that the wire slot driving element may be any device capable of implementing a linear driving, for example, may be implemented by using a cylinder, a linear motor, or a rotary motor in combination with a linear driving mechanism.

The primary function of wire feed module 420 is to grip and feed wire into first threading aperture 805. The wire feeding module 420 may include a wire clamping module and a wire clamping displacement module. The wire clamping module is used for clamping the part, close to the tail end, of the wire rod. The wire clamping displacement module can drive the wire clamping module to move towards a direction approaching to or away from the first threading hole 805 so as to penetrate the tail end of the wire into the first threading hole 805 of the wire coil 800.

As shown in fig. 20, the wire clamping module may include a first wire clamping module 421 and a second wire clamping module 422, wherein the first wire clamping module 421 may be used to clamp a first portion of the wire, and the second wire clamping module 422 may be used to clamp a second portion of the wire. The first portion is closer to the tail end of the wire than the second portion. The wire clamping displacement module may include a first wire clamping displacement device and a second wire clamping displacement device. The first wire clamping displacement device may drive the first wire clamping module 421 and the second wire clamping module 422 to integrally move, so as to pass the tail end of the wire through the first threading hole 805. When the tail end of the wire rod passes through the first threading hole 805, the first wire clamping displacement device stops moving, and the first wire clamping module 421 releases the wire rod, and at this time, the second wire clamping displacement device can drive the second wire clamping module 422 to reciprocate in a direction approaching to and separating from the first threading hole 805 (in this process, the second wire clamping module 422 releases the wire rod when being nearest to the first threading hole 805, and clamps the wire rod again when being farthest from the first threading hole 805, namely, performs the threading action). So that the tail end of the wire rod passes through the second threading hole 806 through the wire guide mechanism 430.

The wire feeding module 420 may further include a wire clamping module lifting device, where the wire clamping module lifting device is configured to drive the first wire clamping module 421 and the second wire clamping module 422 to lift. Therefore, when the tail wire bonding process is needed, the wire clamping module is driven to move to a proper position so as to clamp the wire. The wire clamping module lifting device can be realized by adopting a cylinder, a linear motor or a rotating motor matched with a linear transmission mechanism.

After the tail end of the wire rod sequentially passes through the first threading hole 805 and the second threading hole 806, the tail end of the wire rod can be tensioned to prevent the wire rod from falling off from the first threading hole 805 and the second threading hole 806. In order to implement the automatic tensioning process, as shown in fig. 20, the threading module may further include a wire tensioning module 440, and the wire tensioning module 440 may automatically tension the tail end of the wire passing through the second threading hole 806.

The wire tensioning module 440 may include a tensioning jaw and a tensioning driving member, wherein the tensioning jaw is disposed at the outlet side of the second threading hole 806 to clamp the tail end of the wire passing out of the second threading hole 806. The tensioning driving piece can drive the tensioning clamping jaw to move towards or away from the second threading hole 806 so as to automatically tension the tail end of the wire. The tensioning driving member may be a common driving member such as an air cylinder or a motor, and will not be described herein.

The front end of the wire is the front end of the wire output on the production line when the wire is not wound; the tail end of the wire is the end formed on the wound wire after the wound wire is cut off from the wire on the production line after the winding of the wire on one wire coil 800 is completed.

When the winding of the wire on one coil 800 is completed, the coil 800 can be removed from the automatic winding mechanism 300 and the coil 800 can be weighed and classified, so as to screen and distinguish the unqualified full coil which does not meet the weight requirement from the qualified full coil which meets the weight requirement. So as to unify the specifications of the products. This process may be accomplished automatically using the automated take product weighing mechanism 500. As shown in fig. 2, the self-automated take-off and weigh mechanism 500 may include a take-off device 510 and a weigh device 520, wherein the take-off device 510 is configured to take off a full coil from the automated winding mechanism 300 and transport it to a weigh station; the weighing device 520 can move to a weighing station and can automatically receive the wire coil 800 conveyed by the finished product taking device 510, so as to automatically weigh the wire coil 800.

As shown in fig. 21, the finished product taking device 510 includes a finished product taking clamping jaw 511, a clamping jaw rotating assembly 512 and a clamping jaw moving assembly 513, wherein the finished product taking clamping jaw 511 is used for clamping a wire coil 800, and the clamping jaw rotating assembly 512 is used for driving the finished product taking clamping jaw 511 to rotate, so that the wire coil 800 arranged vertically can be changed into a horizontal arrangement, and the wire coil 800 arranged horizontally is more stable and is not easy to roll when being placed on the weighing device 520. The clamping jaw moving assembly 513 is used for driving the clamping jaw rotating assembly 512 and the finished product clamping jaw 511 to move to a weighing station, so that the wire coil 800 is placed on the weighing device 520 for weighing. The jaw rotation assembly 512 may be implemented using a rotary cylinder or a motor; the jaw moving assembly 513 may be implemented by a guide rail-screw nut structure as shown in fig. 21, but may be implemented by other linear driving structures.

The structure of the weighing device 520 is as shown in fig. 22, the weighing device 520 is located at a weighing station and is movable as a whole, and when the finished product taking device 510 conveys a full coil to the weighing station, the weighing device 520 can move to a position below the finished product taking device 510 along a guide rail 521 at the bottom, and specifically, the weighing device 520 can be driven by a linear cylinder, a motor matched with a screw nut, a motor matched with a gear rack and other linear driving devices. The weighing device 520 further comprises a receiving platform 522, a receiving drive 523 and a weighing platform 524. Wherein the weigh platform 524 is fixed relative to the frame 700; the receiving driving piece 523 is used for driving the receiving platform 522 to move along the vertical direction. When the finished product taking device 510 conveys the full wire coil to the weighing station, the material receiving driving piece 523 drives the material receiving platform 522 to move upwards to the upper side of the weighing platform 524, at this time, the finished product taking device 510 places the full wire coil on the material receiving platform 522, and then the material receiving driving piece 523 drives the material receiving platform 522 to descend until the material receiving platform 522 places the full wire coil on the weighing platform 524. The weighing platform 524 is connected with a weighing sensor, so that the full wire coil can be automatically weighed.

When the wire coil 800 is weighed, the automatic feeding and discharging mechanism 100 loads the wire coil 800 which is finished in winding and qualified in weight into the turnover vehicle 600, and loads the wire coil 800 which is finished in winding and unqualified in weight into the defective product placing bin 701.

It should be noted that, because the empty wire coil is installed in the turnover vehicle, before the wire coil in one storage bin of the turnover vehicle is not moved, the full wire coil cannot be placed in the storage bin, and therefore, the turnover bin 702 can be arranged on the frame of the wire winding device, so that the full wire coil can be temporarily placed in the turnover bin 702 when the full wire coil cannot be placed in the turnover vehicle. In addition, under the condition that space allows, two turnover vehicles can also be arranged, wherein one turnover vehicle is used for placing empty wire coils, and the other turnover vehicle is used for placing full wire coils.
