Description

An automatic cable arrangement mechanism and wire winding equipment

Technical field

This application relates to the technical field of 3D printing consumable production, and in particular to an automatic wire arrangement mechanism and wire rewinding equipment.

Background technique

3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that is based on digital model files and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. .

3D printing filaments are usually produced using an extrusion process. After the filaments are extruded, the filaments need to be wound onto a spool to facilitate transportation and use of the filaments.

Since the wire contains soft materials, a certain tension will be applied to the wire during winding after extrusion molding, so that the wire can maintain a certain amount of stretch. However, if the tension is too high, the wire will easily be stretched and deformed. This causes the cross-sectional area of the wire to become smaller, thus affecting the quality of the wire. When the wire is wound on the reel, as the number of winding layers of the wire continues to increase, the tension of the wire will continue to increase. When it increases to a certain extent, the cross-sectional area of the wire will be smaller than the standard value required by the product, resulting in defective products and even the possibility of the wire breaking.

3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that is based on digital model files and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. .

3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design and other fields, and is gradually used in the direct manufacturing of some products. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering and other fields.

3D printing is usually achieved using a 3D printer. Extrusion 3D printing (Material-ExtrusionBased 3D printing, ME-3DP) is one of the most mainstream forms of polymer material additive manufacturing technology. In extrusion 3D printing technology, Fused Filament Fabrication (FFF) is one of the mainstream technical forms. The principle is to melt the polymer material at high temperature through the printing nozzle of the 3D printer, so that the polymer material obtains melt fluidity, and is extruded from the printing nozzle in a certain metering manner and then accumulated layer by layer.

As a type of 3D printing consumables, linear printing materials come in various types. Especially with the development of technology, the types of 3D printing filaments are becoming increasingly diverse. Filaments used for 3D printing can usually be produced using extrusion production lines. For example, PLA (polylactic acid, polylactic acid), ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer), and PP can be produced through extrusion production lines. (polypropylene, polypropylene), PC (Polycarbonate, polycarbonate), TPU (Thermoplastic Urethane, thermoplastic polyurethane elastomer), PVC (Polyvinylchloride, polyvinyl chloride) and other 3D printing filaments.

After the wire is extruded in the extrusion production line, the wire needs to be wound onto a reel to facilitate transportation and use of the wire. As shown in Figure 1, the rolling process steps of 3D printing filament are roughly as follows:

S1, install the unwound wire reel (hereinafter referred to as the empty reel) on the automatic winding mechanism;

S2, fix the front end of the wire produced by the production line with the bottom hole of the empty reel on the automatic winding mechanism;

S3, start the automatic winding mechanism to drive the empty wire reel to rotate to wind the wire onto the empty wire reel;

S4, when a wire reel is rolled up, cut the wire, and fix the wire end formed by cutting the wire to the wire reel;

S5, remove the wire reel wrapped with wire (hereinafter referred to as the full reel) for weighing, classification and stacking, and install a new empty reel on the automatic winding mechanism for the next round of winding.

When most current winding equipment performs the above-mentioned winding process, each step requires manual participation, so the production efficiency is low, and product quality problems caused by manual misoperation may occur.

In view of this, some embodiments of the present application provide a wire winding device that can realize automated online winding of 3D printing wire, thereby improving production efficiency, reducing manual participation, and avoiding product quality problems caused by manual misoperation. question.

This application will be described in detail below with reference to the accompanying drawings:

Figures 2 and 3 show a wire winding equipment. The wire winding equipment includes an automatic loading and unloading mechanism 100, an automatic wire arrangement mechanism 200, an automatic winding mechanism 300, an automatic ending wire mechanism 400, and automatic finished product weighing. Agency 500. Among them, the automatic loading and unloading mechanism 100 is used to transport empty wire reels and full wire reels, and can be specifically used to perform the above step S1, that is, loading the empty wire reels into the automatic winding mechanism 300 through the automatic loading and unloading mechanism 100. The automatic wire arrangement mechanism 200 and the automatic wire winding mechanism 300 cooperate to execute steps S2 and S3. First, the front end of the wire is automatically inserted into the bottom hole 804 of the wire reel 800 and fixed, and then the automatic wire winding mechanism 300 drives the wire reel 800 to rotate. At the same time, the automatic wire arrangement mechanism 200 adjusts the winding position of the wire on the wire reel 800 so that the wire is wound on the wire reel 800 according to a preset wire arrangement method. The above-mentioned preset cable arrangement method can be selected according to the actual situation, such as arranging the cable from the left end to the right end of the cable drum, and then arranging the cable from the right end to the left end; you can also arrange the cable from the right end of the cable drum to the left end, and then arrange the cable from Arrange the cable from the left end to the right end; you can also start from the middle of the cable reel, first arrange the cable to the left end and then to the right end, etc. The automatic wire ending mechanism 400 is used to perform step S4, that is, to cut the tail end of the coiled wire, and to fix the tail end of the wire to the wire reel 800. The automatic finished product weighing mechanism 500 is used to perform step S5, that is, remove the full wire reel and weigh it. The automatic loading and unloading mechanism 100 can also be used to perform the second half of step S5, that is, to classify and stack the weighed full reels. The above steps can be completed automatically, which can improve wire production efficiency, reduce manual participation, and avoid product quality problems caused by manual misoperation.

It should be noted that, in addition to the above-mentioned mechanisms, as shown in Figure 3, the wire winding equipment may also include a turnover vehicle 600 for placing the wire reel 800, a frame 700 for supporting the entire equipment, etc. Among them, the turnover car 600 can be used to stack empty wire reels and full wire reels. There are many options for storage methods. For example, as shown in Figure 3, the turnover vehicle 600 can be equipped with 8 storage bins. Each storage bin can store 16 wire reels 800. The wire reels 800 are stacked in sequence in the vertical direction. in the storage bin. Of course, you can also choose other storage methods according to production needs. For example, you can also set up 3, 4, 5, 6, 7, 9, 10, etc. storage silos. Each storage bin can also be equipped with 5, 8, 9, 10, 15, 18, 20 and other wire reels 800.

A possible structure of the wire reel 800 is shown in FIG. 4 . The wire reel 800 may include a winding roller 801 and limiting baffles 802 provided at both ends of the winding roller 801 . The winding roller 801 is used to wind the wire, and the limiting baffle 802 is used to limit the wire wound on the winding roller 801 to prevent the wire from falling off both ends of the winding roller 801 . Among them, a central hole 803 is formed along the axial direction in the middle of the winding roller 801. The central hole 803 penetrates the limit baffles 802 at both ends of the winding roller 801. The central hole 803 can be used for the automatic loading and unloading mechanism 100 to clamp the wire reel 800, and also It can be used for the automatic winding mechanism 300 to position the wire reel 800 during winding. The bottom hole 804 of the wire reel 800 is opened on the side wall of the winding roller 801 and is connected with the center hole 803. The bottom hole 804 is used to fix the end of the wire to initially position the wire and the wire reel 800 before winding. .

The above-mentioned mechanisms of the wire winding equipment are described in detail below in combination with the above-mentioned winding process:

Before performing step S1, the empty wire reels can be stacked in the storage bin of the turnover vehicle 600 in the vertical direction, and then the turnover vehicle 600 filled with empty wire reels can be moved to the retrieval station of the wire winding equipment, and Limit the turnover vehicle 600 to prevent the turnover vehicle 600 from moving during the process of picking up and placing materials.

After starting the wire winding equipment, the automatic loading and unloading mechanism 100 executes step S1. The automatic loading and unloading mechanism 100 moves above the turnover vehicle 600, picks up the wire reel 800 in the vertical direction, and then moves to the automatic winding mechanism 300. As shown in Figure 3, the automatic loading and unloading mechanism 100 includes a pick-and-place device 110 and a moving device 120. The pick-and-place device 110 is used to pick up or place the wire reel 800, and the direction of picking and placing the wire reel 800 may be a vertical direction. The moving device 120 is connected to the pick-and-place device 110 to drive the pick-and-place device 110 to move in a horizontal plane to transport the wire reel 800 .

In one application scenario, the wire reel 800 is placed horizontally in the turnover vehicle 600 , and the wire reel 800 is installed vertically on the automatic winding mechanism 300 . Therefore, after the automatic loading and unloading mechanism 100 takes out the wire reel 800 from the turnover car 600, it needs to turn the wire reel 800 over 90° to make the wire reel 800 vertical and then install it on the automatic winding mechanism 300. In order to realize the above process, as shown in FIG. 5 , the picking and placing device 110 includes a first clamping component 111 , a rotating component 112 and a vertical moving component 113 , wherein the first clamping component 111 is used to clamp the wire reel 800 , the rotating component 112 is used to drive the first clamping component 111 to rotate to rotate the wire reel 800 from a horizontal state to a vertical state; and the vertical axis moving component is configured to drive the first clamping component 111 Move in the vertical direction to lift or lower the reel 800, or adjust the position of the reel 800 in the vertical direction when installing the reel 800 on the automatic winding mechanism 300.

The first clamping component 111 can be implemented in various ways. For example, the wire reel 800 can be clamped through the outer circumference of the wire reel 800 , the wire reel 800 can be clamped through the central hole 803 of the wire reel 800 , or the wire reel 800 can be clamped along the outer circumference of the wire reel 800 . The wire reel 800 is clamped in the thickness direction. Specifically, the clamping method can be selected according to the state of the wire reel 800 in the turnover car 600 . For example, the wire reel 800 is placed horizontally in the turnover car 600, and multiple wire reels 800 are stacked one after another in the vertical direction. At this time, if the wire reel 800 is clamped by the outer circumference of the wire reel 800 or along the thickness direction of the wire reel 800, it will be relatively small. Difficult to achieve. Therefore, there is an option to clamp the wire reel 800 through the central hole 803 of the wire reel 800. As shown in Figure 5, the first clamping component 111 can be extended into the central hole 803 of the wire reel 800, and is relatively fixed with the inner wall of the central hole 803 of the wire reel 800 by means of outward expansion support, so as to clamp the wire reel. 800.

Specifically, the first clamping component 111 can be implemented by using a cylinder to drive the clamping jaws to expand outward. The rotating component 112 can be implemented using a rotating motor. The moving device 120 can be implemented by using the truss guide rail shown in Figure 5 in conjunction with a linear transmission mechanism. For example, it can be implemented by a motor driving a rack and pinion transmission, or a motor driving a screw nut, or a linear cylinder. , linear motor and other linear drive methods.

In some specific usage scenarios, the front and back sides of the wire reel 800 need to be distinguished and installed on the automatic winding mechanism 300 in a preset posture. The above-mentioned installation of the wire reel 800 in the preset posture means that when the wire reel 800 is installed on the automatic winding mechanism 300, it is installed according to the preset end face orientation. Assuming that the front side of the reel 800 is preset to be installed toward the driving shaft 320 of the automatic winding mechanism 300, when installing the reel 800, the front and back sides of the reel 800 need to be adjusted first, and then the reel is picked up by the automatic loading and unloading mechanism 100. 800, install the front side of the reel 800 toward the driving shaft 320 of the automatic winding mechanism 300. For example, when arranging wires on the wire drum 800, in order to start arranging the wires from one end of the wire drum 800, the bottom hole 804 of the wire drum 800 is usually disposed close to the first end surface or the second end surface of the wire drum 800. Therefore, before each empty line reel is installed, in order to ensure that the bottom hole 804 of each empty line reel is at the same position in the axial direction after the installation is completed, the front and back sides of the empty line reel need to be identified and adjusted.

In order to automatically realize the above-mentioned steps of distinguishing and adjusting the front and back of the wire reel 800, as shown in Figures 5 and 6, the automatic loading and unloading mechanism 100 also includes an identification device 130 and a turning device 140. The identification device 130 is configured to identify or distinguish the The front and back sides of the reel 800. The identification device 130 can be installed on the pick-and-place device 110 and move with the pick-and-place device 110. When the pick-and-place device 110 picks up the wire reel 800, the recognition device 130 can identify the front and back of the wire reel 800. This saves operating steps. After the recognition by the identification device 130 is completed, the control system determines whether the wire reel 800 needs to be turned over based on the recognition result. If it needs to be flipped, the wire reel 800 will be transported to the flipping device 140 for flipping. If it does not need to be flipped, the wire reel 800 will be directly transported to the automatic winding machine. Line mechanism 300. The flipping device 140 can flip the wire reel 800 to a preset surface facing upward, such as front side up or back side up, according to the identification information of the identification device 130 . It should be noted that the above-mentioned front side and back side are just two definitions given to distinguish the two end surfaces of the wire reel 800. The structures of the front side and the back side may be the same or different, and are not limited here.

The above-mentioned identification device 130 can be a camera, a scanner, etc., and identification marks can be provided on the front and/or back sides of the wire reel 800 so that the identification device 130 can identify the front and back sides of the wire reel 800 by photographing or scanning the identification marks. When the identification device 130 uses a camera, a CCD (charge coupled device, charge coupled device) camera may be used.

As shown in Figure 6, the above-mentioned flipping device 140 includes a fixed bracket 141, a lifting bracket 142, a rotating bracket 143 and a second clamping component 144. The fixed bracket 141 is fixedly installed, and the lifting bracket 142 is slidably installed on the fixed bracket 141, so that It can move vertically relative to the fixed bracket 141 . The rotating bracket 143 is rotatably arranged on the lifting bracket 142 , and the second clamping component 144 is arranged on the rotating bracket 143 , so that the rotating bracket 143 can drive the second clamping component 144 to rotate to flip the wire reel 800 . A reel bracket 145 for placing the reel 800 can be provided next to the turning device 140. After the first clamping component 111 places the reel 800 on the reel bracket 145, the second clamping component 144 is driven by the lifting bracket 142. Clamp the wire reel 800 and turn it over 180° driven by the rotating bracket 143, and then put it back into the wire reel bracket 145 so that the preset surface of the wire reel 800 faces upward. At this time, the first clamping component 111 clamps the wire reel 800 again and rotates it 90°, and then installs the wire reel 800 on the driving shaft 320 of the automatic winding mechanism 300.

After the empty wire reel is installed in the automatic winding mechanism 300, the automatic wire arrangement mechanism 200 and the automatic wire winding mechanism 300 cooperate to perform step S2, in which the automatic wire arrangement mechanism 200 detects the bottom hole 804 of the wire reel 800 and automatically The wire inserted into the bottom hole 804 of the wire reel 800 is pressed tightly by the automatic winding mechanism 300 . This is to prevent the end of the wire from coming out of the bottom hole 804 during the winding process.

As shown in Figures 7 and 8, the automatic cable arrangement mechanism 200 includes a wire feeding nozzle 210, a carrying platform 220, and a carrying platform driving device. The wire feeding nozzle 210 is disposed on the carrying platform 220 and is used to guide the conveying direction of the wire. The carrying platform driving device is connected to the carrying platform 220 and is used to drive the carrying platform 220 to move to change the position of the wire feeding nozzle 210 relative to the automatic winding mechanism 300 .

As shown in Figure 7, the bearing platform 220 is also provided with a bottom hole detection device 230, a control device (not shown in the figure) and an active wire feeding device 240. Among them, the bottom hole detection device 230 can automatically detect the position of the bottom hole 804 of the reel 800 on the automatic winding mechanism 300; the control device can detect the position of the bottom hole 804 when the bottom hole detection device 230 detects the position of the bottom hole 804. The carrying platform 220 is controlled to drive the wire feeding nozzle 210 to move, so that the wire feeding direction of the wire feeding nozzle 210 is toward the bottom hole 804; the active wire feeding device 240 is used to provide an active transporting force to the wire during threading, so as to transfer all the wires. The front end of the wire is fed into the bottom hole 804 of the wire reel 800.

There are many ways to implement the bottom hole detection device 230. For example, it can be implemented by using a reflective photoelectric sensor. The reflective photoelectric sensor usually includes a transmitter and a receiver. Its working principle is to use the transmitter to emit detection light and pass it through the receiver. It receives the detection light reflected by the object and analyzes the state of the reflected detection light to determine the state of the object. The reflective photoelectric sensor has a simple structure, is easy to use and has high detection accuracy. Specifically, the reflective photoelectric sensor may include an infrared reflective photoelectric sensor, a laser reflective photoelectric sensor or an ultrasonic reflective photoelectric sensor.

When a reflective photoelectric sensor is used, the light emitting direction of the reflective photoelectric sensor can be set toward the wire reel 800 on the automatic winding mechanism 300. After the reflective photoelectric sensor is turned on, the emitter in the reflective photoelectric sensor can be directed toward the desired direction. The wire reel 800 emits detection light. During the rotation of the wire reel 800, when the detection light irradiates the winding roller 801 of the wire reel, the detection light is reflected by the winding roller 801 and is thus reflected by the reflective photoelectric system. The receiver in the sensor receives, and if the receiver continues to receive the 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, and the receiver in the reflective photoelectric sensor cannot receive the reflected light signal. At this time, the control device determines that the bottom hole detection device 230 has detected the bottom hole. The location of hole 804. Afterwards, the control device can control the automatic winding mechanism 300 to stop rotating, and the reel 800 stops at the current position. Since the relative position of the wire feeding nozzle 210 and the reflective photoelectric sensor can be preset, at this time, 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 desired position. Describe the bottom hole 804.

As shown in FIG. 9 , the reflective photoelectric sensor can be set at the first preset position, the wire feeding nozzle 210 can be set at the second preset position, and the direction of the detection light L of the reflective photoelectric sensor can be aligned with the feeding direction. The thread feeding direction of the thread nozzle 210 is parallel. In addition, since the automatic loading and unloading mechanism 100 installs the wire reel 800 on the automatic winding mechanism 300 in a preset posture, the bottom hole 804 on each wire reel 800 is fixed in the axial direction of the wire reel 800 , when setting the initial position of the reflective photoelectric sensor (i.e., the first preset position), it can be set to correspond to the position of the bottom hole 804 in the axial direction of the wire disk 800, that is, the detection light is illuminated on the wire disk 800 The position is located on the trajectory along which the bottom hole 804 rotates with the wire reel 800. Therefore, when the detection light does not pass through the bottom hole 804, the control device controls the automatic winding mechanism 300 to drive the reel 800 to continue rotating; until the detection light passes through the bottom hole 804, the control device controls The automatic winding mechanism 300 stops 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 nozzle 210 The wire feeding direction is toward 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 only needs to drive the wire feeding nozzle 210 to translate to the first preset position.

The bottom hole detection device 230 and the wire feeding nozzle 210 can be installed separately or together. When the bottom hole detection device 230 and the wire feeding nozzle 210 can be installed separately, the bottom hole detection device 230 and the wire feeding nozzle 210 can be installed independently. on the carrying platform 220. In addition, in order to make the structure more compact, the bottom hole detection device 230 and the wire feeding nozzle 210 can also be installed together. As shown in Figure 8, the carrying platform 220 can be provided with a wire feeding nozzle bracket 211 and a bottom hole detection device bracket 231. , the wire feeding nozzle 210 is arranged on the wire feeding nozzle bracket 211; the bottom hole detection device bracket 231 is arranged on one side of the wire feeding nozzle bracket 211, and the bottom hole detection device 230 is arranged on the bottom hole detection device bracket 231 superior.

When the wire feeding nozzle 210 is aligned with the bottom hole 804 of the wire reel 800 on the automatic winding mechanism 300, the active wire feeding device 240 provides an active conveying force to the wire to feed the front end of the wire into the bottom hole of the wire reel 800. 804. As shown in FIG. 10 , the active wire feeding device 240 includes a driving wheel 241 , a first pressing wheel 242 , a driving wheel driving member 243 and a driving member of the first pressing wheel 242 (not shown in the figure). Among them, the driving wheel 241 is fixed relative to the carrying platform 220; the first pressing wheel 242 and the driving wheel 241 are arranged oppositely in the vertical direction, and can move in the vertical direction relative to the driving wheel 241. ; The driving wheel driving member 243 is used to drive the driving wheel 241 to rotate. The wire passes between the first compression wheel 242 and the driving wheel 241, and the driving member of the first compression wheel 242 drives the first compression wheel 242 to move downward to compress the wire. The driving wheel driving member 243 drives the driving wheel 241 to rotate, so that the friction between the first pressing wheel 242 and the driving wheel 241 can drive the wire to be transported forward, so that the front end of the wire can be inserted 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 can be provided with anti-skid patterns. The anti-skid patterns can be in the form of a grid or a line structure, so that the driving wheel 241 can provide better transportation to the wire. The force is more stable and prevents slipping when feeding the wire.

The above-mentioned active wire feeding device 240 can adopt the structure shown in Figure 10 when installed on the bearing platform 220. The bearing platform 220 is provided with a driving wheel fixed frame 244. The driving wheel 241 fixed frame is provided with a bearing, and the rotating shaft of the driving wheel 241 is provided with a bearing.

The driving wheel driving component 243 is disposed on the driving component fixing bracket 245, and the output shaft of the driving wheel driving component 243 is connected to the driving wheel 241. It should be noted that when the output shaft of the driving wheel driving member 243 and the rotation shaft of the driving wheel 241 are different in size, the output shaft and the rotation shaft can be connected through a coupling.

The installation method of the first pressing wheel 242 on the bearing platform 220 is shown in Figure 10. The bearing platform 220 is provided with a pressing wheel fixing frame 246, and the pressing wheel fixing frame 246 is provided with a sliding pressing wheel moving frame. 247. The first pressing wheel 242 is arranged on the pressing wheel moving frame 247 and is located above the driving wheel 241. The driving member of the first pressing wheel 242 is connected with the pressing wheel moving frame 247 to drive the pressing wheel moving frame 247 to move in the vertical direction.

The above-mentioned driving wheel driving member 243 can be implemented by a motor or other mechanism capable of realizing rotational driving. The above-mentioned driving member of the first pressing wheel 242 can be implemented by a cylinder, and of course it can also be implemented by other linear driving devices.

It should be noted that the above-mentioned active wire feeding device 240 only needs to provide active conveying force to the wire when the wire penetrates into the bottom hole 804 of the empty wire reel. When the wire enters the bottom hole 804 of the wire reel 800, the automatic winding mechanism 300 The empty wire reel can be driven to rotate, thereby providing active conveying force to the wire through the automatic winding mechanism 300. At this time, the active wire feeding device 240 can be closed.

When the front end of the wire penetrates into the bottom hole 804, in order to prevent the wire from coming out of the bottom hole 804, the automatic winding mechanism 300 can be used to tighten the front end of the wire that has penetrated into the bottom hole 804. As shown in Figures 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 crimping device. The fixed base 310 is fixedly installed on the frame 700, and the driving shaft 320 is arranged on the fixed base 310. The driving shaft driving member 330 is used to drive the driving shaft 320 to rotate. The crimping device is arranged opposite to the driving shaft 320. When the automatic loading and unloading mechanism 100 installs the wire reel 800 on the automatic winding mechanism 300, first the first end of the central hole 803 of the wire reel 800 is sleeved on the driving shaft 320, and then the automatic loading and unloading mechanism 100 releases the wire reel 800. , the wire pressing device extends into the wire drum 800 from the second end of the central hole 803 to compress the wire penetrating into the bottom hole 804 of the wire drum 800 .

As shown in Figures 12 and 15, the crimping device includes a moving base 340 arranged opposite to the fixed base 310. The moving base 340 can move along the axial direction of the driving shaft 320. The moving base 340 is provided with an auxiliary The shaft 350 and the auxiliary shaft 350 are coaxially arranged with the driving shaft 320 . The auxiliary shaft 350 and the mobile base 340 can be connected through bearing support. The inner ring of the bearing is cooperatively connected with the auxiliary shaft 350. The outer ring of the bearing is cooperatively connected with the bearing seat on the mobile base 340. The driving member drives the driving shaft 320 to rotate. At this time, the driving shaft 320 drives the auxiliary shaft 350 and the inner ring of the bearing to rotate through the friction between the driving shaft 320 and the wire disk 800, while the outer ring of the bearing and the bearing seat are fixed and do not rotate. The auxiliary shaft 350 is connected to an auxiliary shaft moving assembly 360. 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 moves out of the central hole 803. the second end. As shown in Figures 15 and 16, the auxiliary shaft 350 has an axial through hole, and the crimping shaft 370 is inserted into the axial through hole of the auxiliary shaft 350 and can slide in the axial direction relative to the auxiliary shaft 350. The crimping shaft 370 is connected to a crimping shaft driving assembly 380. The crimping shaft driving assembly 380 can drive the crimping shaft 370 to slide along the axial direction of the auxiliary shaft 350 to extend or retract the auxiliary shaft 350. When the When the wire pressing shaft 370 extends out of the auxiliary shaft 350, the wire pressing shaft 370 will compress the wire penetrating into the bottom hole 804. It should be noted that the above-mentioned pressing shaft 370 can press the wire on the driving shaft 320 when compressing the wire.

There are many ways to implement the above-mentioned auxiliary shaft moving assembly 360, as long as it can drive the auxiliary shaft 350 to move in a straight line. For example, as shown in FIG. 15 , the auxiliary shaft moving assembly 360 includes an auxiliary shaft guide rail 361 and a screw nut assembly for driving the moving base 340 to slide along the auxiliary shaft guide rail 361 . Among them, the auxiliary shaft guide rail 361 is arranged along the axial direction of the driving shaft 320, and the moving base 340 is slidingly connected with the auxiliary shaft guide rail 361. The screw nut assembly includes the auxiliary shaft screw 362 and the auxiliary shaft 350 nut (not shown in the figure). ) and the auxiliary shaft motor 363. The auxiliary shaft screw 362 is arranged in parallel with the auxiliary shaft guide rail 361. The auxiliary shaft 350 nut is fixed on the moving base 340 and is threaded with the auxiliary shaft screw 362. The auxiliary shaft motor 363 and the auxiliary shaft The screw 362 is connected in transmission to drive the auxiliary shaft screw 362 to rotate. It should be noted that the screw nut assembly is only one possible implementation of the auxiliary shaft moving assembly 360. The auxiliary shaft moving assembly 360 can also be implemented using a gear rack assembly, a linear cylinder, a linear motor, and other structures. In addition, there are many ways of transmission connection between the above-mentioned auxiliary shaft motor 363 and the auxiliary shaft screw 362. For example, the auxiliary shaft motor 363 and the auxiliary shaft screw 362 can be directly connected, or indirectly connected through other transmission components. The transmission components can be Gear transmission, chain transmission and other transmission methods, the structure shown in Figure 15 adopts the belt transmission method of pulleys and belts, and the output shaft of the motor is set parallel to the screw and arranged in the up and down direction, so it can save Horizontal arrangement of space.

There are many ways to implement the above-mentioned crimping shaft driving assembly 380, as long as it can drive the crimping shaft 370 to expand and contract relative to the auxiliary shaft 350. In one implementation, as shown in Figures 17 and 18, the crimping shaft driving assembly 380 includes a crimping cylinder 381, and the piston rod of the crimping cylinder 381 is connected to the crimping shaft 370 to drive the crimping shaft 370 along the auxiliary axis. 350 axial sliding. In order to keep the crimping shaft 370 in the retracted state when the wire is not being crimped, a reset member 382 may also be provided. The reset member 382 is connected to the crimping shaft 370 to apply a reset force to the crimping shaft 370 to maintain the retracted state. Specifically, the reset member 382 may be implemented by elastic members such as springs and elastic pieces.

When the return member 382 adopts a spring, the installation structure of the return member 382 is as shown in Figure 17. A spring receiving cavity is provided between the auxiliary shaft 350 and the line pressing shaft 370, and a first positioning cavity is provided on the outer wall of the line pressing shaft 370. part 383, the inner wall of the auxiliary shaft 350 is provided with a second positioning part 384, and the second positioning part 384 is located outside the first positioning part 383 (that is, on the side close to the driving shaft 320), and the spring The accommodation cavity is located between the first positioning part 383 and the second positioning part 384. The spring is located in the spring accommodation cavity. One end of the spring is in contact with the first positioning part 383. The other end of the spring is in contact with the second positioning portion 384 . The spring is always kept in a compressed state, and the restoring force of the spring keeps the spool 370 in a retracted state. This can prevent the crimping shaft 370 from protruding from the auxiliary shaft 350 or falling out of the axial through hole of the auxiliary shaft 350 when crimping is not being performed.

In order to guide the telescopic movement of the crimping shaft 370, as shown in Figure 18, the crimping shaft driving assembly 380 also includes a crimping shaft guide rail 385 and a crimping shaft sliding bracket 386. The crimping shaft guide rail 385 is disposed on the mobile base 340. , and extends along the axial direction of the driving shaft 320 . The crimping shaft sliding bracket 386 is in sliding fit with the crimping shaft guide rail 385 and is connected to the piston rod of the crimping cylinder 381 . The crimping shaft 370 is disposed on the crimping shaft sliding bracket 386 . Therefore, the crimping shaft 370 can be accurately guided through the crimping spool guide rail 385 and the spooling sliding bracket 386, thereby making the crimping spool 370 move more smoothly.

Due to the small size of the wire, in order to increase the crimping area and prevent the wire end from being pressed, as shown in Figure 17, a crimping block 371 can also be provided at the outer end of the crimping shaft 370. The outer diameter of the crimping block 371 is larger than The outer diameter of the crimping shaft 370 can thereby increase the crimping area and ensure the success rate of crimping. In addition, the material of the crimping block 371 can be elastic material, such as rubber, nylon, etc., to prevent damage to the wire during the crimping process.

When the front end of the wire penetrates into the bottom hole 804 and is pressed tightly by the spool 370, step S3 is started, and the driving shaft 320 of the automatic winding mechanism 300 drives the wire reel 800 to rotate to wind up the wire.

There are many ways to implement the driving shaft driving member 330, as long as it can drive the driving shaft 320 to rotate. For example, the driving shaft driving member 330 may include a driving motor of the driving shaft 320 and a transmission assembly. The driving motor of the driving shaft 320 drives the driving shaft 320 through the transmission assembly. Shaft 320 rotates. There are many ways to implement transmission components. For example, you can choose to use belt transmission components, chain transmission components, gear transmission components, etc. Among them, the gear transmission component can use a cylindrical gear set or a bevel gear set, and the bevel gear is a bevel gear. Specifically, a straight bevel gear or a spiral bevel gear can be used. The bevel gear set can be used to transmit power between two intersecting shafts, thereby saving axial layout space. In the solution shown in FIG. 13 , the drive motor of the drive shaft 320 is arranged in the vertical direction, and the output shaft of the drive motor of the drive shaft 320 is perpendicular to the drive shaft 320 . The bevel gear set includes a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is fixedly connected to the output shaft, and the second bevel gear is fixedly connected to the driving shaft 320 , thereby realizing the coupling between the output shaft and the driving shaft 320 . power transmission and saves axial layout space.

There are many ways to realize the rotation of the wire reel 800 with the driving shaft 320. For example, a transmission structure similar to a key transmission can be provided between the wire reel 800 and the driving shaft 320, or between the wire reel 800 and the first pressing part 321, so that The wire reel 800 can rotate synchronously with the driving shaft 320 . In addition, the structure shown in Figures 13 and 15 can also be used. The driving shaft 320 is provided with a first pressing part 321, and the auxiliary shaft 350 is provided with a second pressing part 351. When it is necessary to install a wire on the driving shaft 320 When the wire reel 800 is installed, the wire crimping device can be moved in a direction away from the driving shaft 320 to reserve sufficient operating space for installing the wire reel 800. When the wire reel 800 is sleeved on the driving shaft 320, the first pressing portion 321 abuts against the first end surface of the wire reel 800. At this time, the auxiliary shaft 350 can be driven closer to the position through the auxiliary shaft moving assembly 360. As the driving shaft 320 moves, the second pressing part 351 gradually approaches the first pressing part 321, and finally abuts against the second end surface of the wire reel 800, so that the first pressing part 321 and the second pressing part The portion 351 clamps the wire drum 800 along the axial direction of the wire drum 800 . Then the driving shaft driving part 330 is started, so that the driving shaft driving part 330 drives the driving shaft 320 to rotate to wind the wire onto the wire reel 800 . The first end surface and the second end surface of the above-mentioned wire drum 800 are respectively two end surfaces arranged along the axial direction of the wire drum 800, that is, the outer surfaces of the limiting baffles 802 at both ends of the wire drum 800 in Figure 4.

It should be noted that the bottom hole 804 of the wire reel 800 can be positioned away from the driving shaft 320, thereby preventing the wire from being blocked by the bottom hole 804 when threading. Since the wires are arranged from one end of the winding roller 801, in order to avoid the bottom hole 804, the length of the driving shaft 320 can be set shorter. However, when the first end of the central hole 803 of the wire reel 800 is sleeved on the driving shaft 320, the automatic loading and unloading mechanism 100 releases the wire reel 800. At this time, because the driving shaft 320 is short, the central hole 803 of the wire reel 800 Only part of the sleeve is mounted on the driving shaft 320, so there may be a risk of falling off. In order to solve the above problem, a wire reel clamping assembly 390 can be provided on one side of the driving shaft 320. The wire reel clamping assembly 390 is configured to clamp the wire reel 800 sleeved on the driving shaft 320 to the third On a pressing part 321. Thereby, the wire reel 800 can be temporarily fixed before the second pressing part 351 clamps the wire reel 800 to prevent the wire reel 800 from falling off from the driving shaft 320 . When the first pressing part 321 and the second pressing part 351 press the first reel at the same time, the reel clamping assembly 390 releases the reel 800 .

As shown in Figure 13, the wire reel clamping assembly 390 includes a wire reel clamp 391 and a clamping cylinder 392. One end of the clamping cylinder 392 away from the wire reel clamp 391 is hingedly connected to the fixed base 310. The wire reel clamp The claw 391 is provided on the fixed base 310 and is located on one side of the first pressing part 321; the clamping cylinder 392 is connected to the reel clamp 391 and is configured to drive the reel clamp 391 opens and closes to clamp or loosen the reel 800. As shown in FIG. 13 , the reel clamping claw 391 may include a first hinge part 3911 , a second hinge part 3912 and a clamping part 3913 . The first hinge part 3911 is hinged with the fixed base 310; the second hinge part 3912 is hinged with the piston rod of the clamping cylinder 392; the clamping part 3913 is used to contact the wire reel 800 to clamp the wire reel 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 close to the wire reel 800 to clamp the wire reel 800 ; When the piston rod of the clamping cylinder 392 is retracted, the piston rod drives the clamping portion 3913 to rotate around the first hinge portion 3911 in a direction away from the wire reel 800 to loosen the wire reel 800 .

In the process of the automatic winding mechanism 300 driving the wire reel 800 to rotate and wind up, the automatic wire arrangement mechanism 200 can be used to arrange the wire. The main function of the automatic wire arrangement 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 arranged more evenly on the winding roller 801 of the entire wire reel 800.

During the winding process, the automatic wire arrangement mechanism 200 drives the wire feeding nozzle 210 to move for wire arrangement. When arranging the wire, in order to make the wire evenly wound on the winding roller 801 of the wire reel 800, the wire can be arranged along the axial direction of the winding roller 801. Therefore, one function of the carrying platform 220 is to drive the wire feeding nozzle. 210 moves along the first horizontal direction (that is, the axial direction of the wire reel 800 on the automatic winding mechanism 300) to achieve uniform axial arrangement of the wire on the winding roller 801.

In addition, since the wire contains soft materials, after the wire is extruded, a certain tension will be applied to the wire during winding to maintain a certain stretch of the wire. However, if the tension is too high, the wire will easily be stretched. Deformation causes the cross-sectional area of the wire to become smaller, thus affecting the quality of the wire. When the wire is wound on the wire reel 800, as the number of wire winding layers continues to increase, since the relative position of the wire feeding nozzle 210 and the wire reel 800 remains unchanged, the tension of the wire will continue to increase. When it increases to a certain extent, the cross-sectional area of the wire will be smaller than the standard value required by the product, and the wire may even break. In order to avoid the above problem, the distance between the wire feeding nozzle 210 and the wire reel 800 can be adjusted in real time according to changes in the number of winding layers of the wire on the wire reel 800, so that the tension of the wire remains unchanged. Therefore, another 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 reel 800) to adjust the wire feeding nozzle 210 and the wire reel. 800, and drive the wire feeding nozzle 210 to move in the vertical direction to adjust the height of the wire feeding nozzle 210 relative to the wire reel 800, so that the wire feeding nozzle 210 and the wire can be adjusted in two dimensions. The relative position of the disc 800 is adapted to changes in the number of winding layers of the wire on the wire disc 800, so that the tension of the wire is maintained within a preset range. For example, during the winding process, as the number of wire winding layers increases, the carrying platform driving device drives the carrying platform to move away from the wire reel, thereby maintaining the wire between the wire feeding nozzle and the wire reel. The length is always maintained within the preset range, thereby preventing the wire tension from continuously increasing and keeping the wire tension within the preset range during the winding process.

It should be noted that the length of the wire between the wire feeding nozzle and the wire reel refers to the length of the wire located behind the wire outlet end of the wire feeding nozzle and before being wound onto the winding roller. The distance that the bearing platform driving device drives the bearing platform to move in the direction away from the wire reel can be preset according to the number of winding layers of the wire on the wire reel. For example, it can be preset that each additional layer of the winding layer number increases the load-carrying distance. The table moves a certain distance away from the wire reel.

In addition, in addition to adjusting the distance between the wire feeding nozzle and the wire reel, the tension of the wire can also be maintained by adjusting the position of the wire feeding nozzle in the vertical direction. For example, if the tangent point between the wire and the winding roller is located at the upper edge of the winding roller, moving the wire feeding nozzle upward can increase the length of the wire between the wire feeding nozzle and the wire reel, thereby reducing the tension of the wire; Conversely, if the tangent point between 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 reel, and can also reduce the length of the wire. tension.

In order to realize the above-mentioned movement of the carrying platform 220, as shown in Figures 7 and 9, the carrying platform driving device includes an X-axis moving component 250, a Y-axis moving component 260 and a Z-axis moving component 270. wherein, the 800 axial position. For example, during the wire arrangement process, the X-axis moving component 250 drives the carrying platform 220 to reciprocate along the first horizontal direction, so that the wire can be wound and taken up in multiple layers on the winding roller of the wire reel. Moreover, a limit sensor can also be provided to control the range in which the X-axis moving assembly 250 drives the carrying platform 220 to move along the first horizontal direction, so that the range is adapted to the length of the winding roller of the reel.

Upper staggered setting. That is, 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 located between two adjacent lower guide wheels. Therefore, when the wire passes between the upper guide wheel set 2821 and the lower guide wheel set 2822, the wire can have a larger contact area with the upper guide wheel and the lower guide wheel, so that the wire as a whole is affected during the transmission process.

After the wire is wound up on the wire reel 800, step S4 can be performed, that is, the wire is cut and fixed with the wire reel 800 to complete the finishing wire process. It should be noted that the above-mentioned tail wire can be understood as the tail end of the wire wound on the wire reel 800 . After the wire winding is completed, the tail end of the wire needs to be fixed or knotted with the wire reel 800 to prevent the wire wound on the wire reel 800 from loosening. The ending thread means to tie the tail thread, and the ending thread process is a process of fixing or knotting the tail end of the wire with the wire reel 800 .

The above-mentioned finishing line process can be realized by the automatic finishing line mechanism 400. As shown in Figures 19 and 20, the automatic thread ending mechanism 400 can be provided on the automatic thread winding mechanism 300. The automatic thread ending mechanism 400 includes a thread cutting module 410 and a threading module. The wire trimming module 410 is used to automatically cut off the end of the wire that is not wound on the wire reel 800 to form the tail end of the wire after the wire is wound and wound on the wire reel 800 . The threading module is used to automatically thread the tail end of the wire into the threading hole of the wire drum 800 and fix it.

Pass the tail end of the wire through the first threading hole in sequence. The threading hole 805 and the second threading hole 806 are tightened to complete the relative fixation of the wire and the wire reel 800 . As shown in Figure 20, the first threading hole 805 and the second threading hole 806 can be disposed on the same side of the wire drum 800. At this time, when threading, the tail end of the wire can be passed through the first threading hole 805 first, and then the The tail end of the wire is reversed and then inserted into the second threading hole 806 to complete the fixation of the wire relative to the wire drum 800 . In order to realize the above process, the threading module includes a wire feeding module 420 and a wire guide mechanism 430 . The wire feeding module 420 can automatically thread the tail end of the wire into the first threading hole 805 of the wire reel 800 . The wire guide mechanism 430 is configured to guide the tail end to pass through the second wiring hole 806 after the tail end passes through the first wiring hole 805 .

The above-mentioned automatic wire ending mechanism 400 is provided with a wire guide mechanism 430, and the wire guide mechanism 430 can guide the tail end to pass through the second wire threading hole 806 after the tail end passes through the first wire threading hole 805, so the wire feeding module When threading 420, you only need to continuously feed the wire into the first threading hole 805. After the wire enters the first threading hole 805, the direction will be reversed under the action of the wire conductor mechanism 430, and as the wire feeding module 420 continues to The feeding wire gradually passes through the second threading hole 806. Therefore, there is no need for the wire feeding module 420 to perform complicated threading operations to complete the fixing of the wire and the wire reel 800, which is more convenient to implement.

The wire guide mechanism 430 may include a wire trough assembly and a wire trough driver (not shown). As shown in Figure 20, the wire trough assembly includes a base plate 431 and a wire groove 432 provided on the first surface of the base plate 431. The first end of the wire groove 432 faces the first wiring hole 805, so The second end of the wire groove 432 faces the second wire hole 806 . Therefore, when the tail end of the wire passes through the first wire hole 805, it can enter the wire groove 432 from the first end of the wire groove 432, and the wire can bend and turn under the guidance of the wire groove 432 by relying on its own flexibility. , gradually passes out from the second end of the wire groove 432 and passes through the second wire hole 806 .

It should be noted that the first end of the above-mentioned wire groove 432 faces the first wire hole 805. The first end of the wire groove 432 may be directly connected to and connected with the first wire hole 805, or it may be a wire recess. The first end of the slot 432 is opposite to the first threading hole 805 and has a certain gap. Similarly, the second end of the above-mentioned wire groove 432 faces the second threading hole 806. The second end of the wire groove 432 and the second threading hole 806 may be directly attached to and connected to each other, or the second end of the wire groove 432 may be directly connected to the second threading hole 806. The second end is opposite to the second threading hole 806 and has a certain gap.

The above-mentioned wire trough driving member is used to drive the wire trough assembly to move closer to or away from the wire drum 80011. Therefore, when the finishing line process is required, the wire trough driving member can move the wire trough assembly closer to the wire drum. Move in the direction of 800 so that the two ends of the wire trough assembly are connected to the first threading hole 805 and the second threading hole 806 respectively. After the wire-ending process is completed, the wire trough driver can move the wire trough assembly away from the wire reel 800 to separate the wire trough assembly from the wire, thereby making it easier to remove the wound wire reel 800 .

It should be noted that the above-mentioned wire trough driving member can be any device that can realize linear driving. For example, it can be realized by using a cylinder, a linear motor or a rotary motor in conjunction with a linear transmission mechanism.

The first part is closer to the tail end of the wire than the second part. The clamping displacement module may include a first clamping displacement device and a second clamping displacement device. The first wire clamping displacement device can drive the first wire clamping module 421 and the second wire clamping module 422 to move as a whole, so as to pass the tail end of the wire through the first threading hole 805 . When the tail end of the wire 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. At this time, the second wire clamping displacement device can drive the second wire clamping displacement device. The wire clamping module 422 reciprocates in the direction closer to and away from the first wire threading hole 805 (during this process, the second wire clamping module 422 releases the wire when it is closest to the first wire threading hole 805, and when it is furthest away from the first wire threading hole 805, it releases the wire. At 805, clamp the wire again and perform threading action). The tail end of the wire passes through the wire guide mechanism 430 and passes through the second wire hole 806 .

The wire feeding module 420 may also include a wire clamping module lifting device. The wire clamping module lifting device is used to drive the first wire clamping module 421 and the second wire clamping module 422 to lift. Therefore, when the finishing wire process is required, the wire clamping module is driven to move to a suitable position to facilitate clamping of the wire. The lifting device of the clamping module can be realized by using a cylinder, a linear motor or a rotary motor combined with a linear transmission mechanism.

After the tail end of the wire passes through the first threading hole 805 and the second threading hole 806 in sequence, the tail end of the wire can be tightened to prevent the wire from falling off from the first threading hole 805 and the second threading hole 806 .

The tensioning driver can drive the tensioning clamp to move closer to or away from the second threading hole 806 to automatically tighten the tail end of the wire. The above-mentioned tightening driving parts can use common driving parts such as cylinders and motors, which will not be described in detail here.

It should be noted that the front end of the above-mentioned wire refers to the front end of the wire output from the production line when the wire is not coiled; the tail end of the wire refers to the coiled wire after the wire is wound on a wire reel 800. The end formed on the coiled wire after the wire is cut off from the wire on the production line.

After the wire on a reel 800 is wound up, the reel 800 can be removed from the automatic winding mechanism 300 and weighed and classified. The purpose is to classify the unqualified products that do not meet the weight requirements. Screening and differentiation of wire reels and qualified full wire reels that meet weight requirements.

The finished product clamp 511 is used to clamp the wire reel 800, and the clamp rotating assembly 512 is used to pick up the wire reel 800. The clamping jaw 511 for taking out the finished product is driven to rotate, so that the vertically arranged wire reel 800 can be turned into a horizontal arrangement. When the horizontally arranged wire reel 800 is placed on the weighing device 520, it is more stable and less likely to roll. The clamping jaw moving assembly 513 is used to drive the clamping jaw rotating assembly 512 and the finished product clamping jaw 511 to move to the weighing station, and then place the wire reel 800 on the weighing device 520 for weighing. The above-mentioned clamping jaw rotating assembly 512 can be implemented by a rotating cylinder or a motor; the above-mentioned clamping jaw moving assembly 513 can be implemented by using the structure of a guide rail and a screw nut as shown in Figure 21.
