Abstract
Description
Technical Field
[0001] This application relates to the field of 3D printing consumables production technology, and in particular to an automatic filament winding mechanism and filament winding equipment. Background Technology
[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as a basis and employs bondable materials such as powdered metal or plastic to construct objects by printing layer by layer.
[0003] 3D printing filaments are typically produced using an extrusion process. After the filament is extruded, it needs to be wound onto a spool for easy transport and use.
[0004] Because the wire contains soft materials, a certain tension is applied to the wire during winding after extrusion to maintain a certain amount of stretch. However, if the tension is too high, the wire can easily be stretched and deformed, resulting in a smaller cross-sectional area and affecting its quality. As the wire is wound on the reel, the tension increases with the number of winding layers. When this tension reaches a certain level, the cross-sectional area may fall below the standard value required for the product, leading to defective products or even wire breakage. Summary of the Invention

[0066] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as a basis and employs bondable materials such as powdered metal or plastic to construct objects by printing layer by layer.
[0067] 3D printing is typically achieved using digital material printers. It is commonly used in mold making and industrial design to create models, and is increasingly being applied to the direct manufacturing of some products. This 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.
[0068] 3D printing is typically achieved using a 3D printer. Material-Extrusion Based 3D printing (ME-3DP) is one of the most mainstream forms of additive manufacturing technology for polymer materials. Within extrusion 3D printing, filament fabrication (FFF) is a key technique. Its principle involves melting polymer material at high temperatures using the 3D printer's nozzle, achieving melt flow, and then extruding the melt layer by layer through the nozzle in a metered manner to form the final shape.
[0069] Linear printing materials, as a type of 3D printing consumable, are diverse and complex, especially with the development of technology, the types of 3D printing filaments are becoming increasingly diversified. Filaments used for 3D printing are usually produced using extrusion production lines. For example, PLA (polylactic acid), ABS (acrylonitrile butadiene styrene copolymer), PP (polypropylene), PC (polycarbonate), TPU (thermoplastic urethane), and PVC (polyvinyl chloride) 3D printing filaments can be produced through extrusion production lines.
[0070] After the wire is extruded into shape on the extrusion production line, it needs to be wound onto a spool for transportation and use. For example... Figure 1 As shown, the winding process of 3D printing filaments generally involves the following steps:
[0071] S1, Install the unwound wire spool (hereinafter referred to as the empty wire spool) onto the automatic winding mechanism;
[0072] S2, fix the front end of the wire produced by the production line to the bottom hole of the empty wire reel on the automatic winding mechanism;
[0073] S3, start the automatic winding mechanism to drive the empty wire reel to rotate, so as to wind the wire onto the empty wire reel;
[0074] S4. After a spool is wound up, the wire is cut and the cut end of the wire is fixed to the spool.
[0075] S5, remove the coil with the wire (hereinafter referred to as the full coil) for weighing and sorting, and load a new empty coil into the automatic winding mechanism for the next round of winding.
[0076] Most current winding equipment requires manual intervention at each step of the winding process, resulting in low production efficiency and potential product quality issues due to human error.
[0077] In view of this, some embodiments of this application provide a filament winding device that can realize automated online winding of 3D printed filaments, thereby improving production efficiency, reducing manual intervention, and avoiding product quality problems caused by human error.
[0078] The present application will now be described in detail with reference to the accompanying drawings:
[0079] Figure 2 and Figure 3A wire winding device is shown, comprising an automatic loading and unloading mechanism 100, an automatic wire arrangement mechanism 200, an automatic winding mechanism 300, an automatic wire ending mechanism 400, and an automatic finished product weighing mechanism 500. The automatic loading and unloading mechanism 100 is used to transport empty and full wire reels, specifically for performing step S1, i.e., loading empty wire reels into the automatic winding mechanism 300. The automatic wire arrangement mechanism 200 and the automatic winding mechanism 300 cooperate to perform 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. Then, while the automatic winding mechanism 300 rotates the wire reel 800, the automatic wire arrangement mechanism 200 adjusts the winding position of the wire on the wire reel 800, so that the wire is wound onto the wire reel 800 according to a preset arrangement method. The aforementioned preset wire routing method can be selected according to actual conditions. For example, the wire can be routed from the left end of the coil to the right end, and then from the right end to the left end; or the wire can be routed from the right end of the coil to the left end, and then from the left end to the right end; or the wire can be routed from the middle of the coil, first 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 off the tail end of the wound wire and fix the tail end of the wire to the coil 800. The automatic finished product weighing mechanism 500 is used to perform step S5, that is, to remove the full coil and weigh it. The automatic loading and unloading mechanism 100 can also be used to perform the latter half of step S5, that is, to classify and stack the weighed full coils. All of the above steps can be completed automatically, thereby improving the production efficiency of wire, reducing manual intervention, and avoiding product quality problems caused by human error.
[0080] It should be noted that, in addition to the institutions mentioned above, such as Figure 3 As shown, the wire winding equipment may also include a turnover cart 600 for placing the wire reels 800, a frame 700 for supporting the entire equipment, etc. The turnover cart 600 can be used to stack empty and full wire reels. There are various options for material storage methods, such as... Figure 3 As shown, the turnover cart 600 can be equipped with 8 storage bins, each capable of holding 16 wire reels 800, which are stacked vertically within the bins. Of course, other storage methods can be selected according to production needs; for example, 3, 4, 5, 6, 7, 9, or 10 storage bins can be configured. Each storage bin can also hold 5, 8, 9, 10, 15, 18, or 20 wire reels 800.
[0081] One possible structure of the spool 800 is as follows: Figure 4As shown, the spool 800 may include a winding roller 801 and limiting baffles 802 disposed at both ends of the winding roller 801. The winding roller 801 is used to wind the wire, and the limiting baffles 802 are used to limit the wire wound on the winding roller 801 to prevent the wire from falling off from both ends of the winding roller 801. A central hole 803 is formed axially in the middle of the winding roller 801, and the central hole 803 penetrates the limiting baffles 802 at both ends of the winding roller 801. The central hole 803 can be used by the automatic loading and unloading mechanism 100 to clamp the spool 800, and can also be used by the automatic winding mechanism 300 to position the spool 800 during winding. A bottom hole 804 is formed on the side wall of the winding roller 801 and communicates with the central hole 803. The bottom hole 804 is used to fix the end of the wire to the spool 800 for preliminary positioning of the wire before winding.
[0082] The following provides a detailed explanation of each mechanism of the wire winding equipment in conjunction with the above winding process:
[0083] Before performing step S1, empty wire reels can be stacked vertically in the storage bin of the turnover cart 600. Then, the turnover cart 600 filled with empty wire reels is moved to the material handling station of the wire winding equipment, and the turnover cart 600 is limited to prevent it from moving during the material handling process.
[0084] After starting the wire winding equipment, the automatic loading and unloading mechanism 100 executes step S1, moving above the transfer cart 600, picking up the wire reel 800 vertically, and then moving to the automatic winding mechanism 300. For example... Figure 3 As shown, the automatic loading and unloading mechanism 100 includes a picking and placing device 110 and a moving device 120. The picking and placing device 110 is used to pick up or place the reel 800, and its picking and placing direction for the reel 800 can be vertical. The moving device 120 is connected to the picking and placing device 110, thereby driving the picking and placing device 110 to move in the horizontal plane to transport the reel 800.
[0085] In one application scenario, the spool 800 is placed horizontally in the turnover cart 600, while it is installed vertically on the automatic winding mechanism 300. Therefore, after the automatic loading and unloading mechanism 100 removes the spool 800 from the turnover cart 600, it needs to rotate the spool 800 by 90° to make it vertical before installing it onto the automatic winding mechanism 300. To achieve this process, as follows... Figure 5As shown, the pick-and-place device 110 includes a first clamping assembly 111, a rotating assembly 112, and a vertical moving assembly 113. The first clamping assembly 111 is used to clamp the spool 800, the rotating assembly 112 is used to drive the first clamping assembly 111 to rotate the spool 800 from a horizontal state to a vertical state, and the vertical axis moving assembly is configured to drive the first clamping assembly 111 to move in the vertical direction to lift or lower the spool 800, or to adjust the position of the spool 800 in the vertical direction when the spool 800 is installed on the automatic winding mechanism 300.
[0086] There are several ways to implement the first clamping component 111. For example, the wire spool 800 can be clamped by its outer circumference, by its central hole 803, or along its thickness. The clamping method can be selected based on the state of the wire spool 800 in the turnover cart 600. For instance, if the wire spool 800 is placed horizontally in the turnover cart 600, and multiple wire spools 800 are stacked vertically, clamping the wire spool 800 by its outer circumference or along its thickness is difficult. Therefore, clamping the wire spool 800 by its central hole 803 is a better option. Figure 5 As shown, the first clamping component 111 can extend into the center hole 803 of the coil 800 and is fixed relative to the inner wall of the center hole 803 of the coil 800 by means of outward expansion support, so as to clamp the coil 800.
[0087] Specifically, the first gripping component 111 can be implemented by using a cylinder to drive the gripper to expand outward. The rotating component 112 can be implemented by using a rotary motor. The moving device 120 can be implemented by using... Figure 5 The truss guide rail shown is used in conjunction with a linear transmission mechanism. For example, it can be achieved by using a motor to drive a gear and rack transmission, or by using a motor to drive a lead screw and nut transmission, or by using other linear drive methods such as linear cylinders and linear motors.
[0088] In certain specific application scenarios, the reel 800 needs to be distinguished by its front and back sides and installed in a preset posture on the automatic winding mechanism 300. Installing the reel 800 in a preset posture means that when installing the reel 800 onto the automatic winding mechanism 300, it is installed with its end face facing a pre-defined orientation. Assuming the front side of the reel 800 is pre-set to face the drive shaft 320 of the automatic winding mechanism 300, the front and back sides of the reel 800 need to be adjusted before installation. Then, the automatic loading / unloading mechanism 100 picks up the reel 800 and installs it with its front side facing the drive shaft 320. For example, when laying wire on the reel 800, in order to start laying wire from one end of the reel 800, the bottom hole 804 of the reel 800 is usually located near the first or second end face of the reel 800. Therefore, before each installation of the empty wire reel, in order to ensure that the bottom hole 804 of each empty wire reel is in the same position in the axial direction after installation, it is necessary to identify and adjust the front and back of the empty wire reel.
[0089] To automatically perform the above steps of distinguishing and adjusting the front and back of the spool 800, such as... Figure 5 , Figure 6 As shown, the automatic loading and unloading mechanism 100 also includes an identification device 130 and a flipping device 140. The identification device 130 is configured to identify or distinguish the front and back sides of the coil 800. The identification device 130 can be mounted on the pick-and-place device 110 and moves with the pick-and-place device 110. When the pick-and-place device 110 picks up the coil 800, the identification device 130 can identify the front and back sides of the coil 800, thus saving operation steps. After the identification device 130 completes the identification, the control system determines whether the coil 800 needs to be flipped based on the identification result. If it needs to be flipped, the coil 800 is transported to the flipping device 140 for flipping; if it does not need to be flipped, the coil 800 is directly transported to the automatic winding mechanism 300. The flipping device 140 can flip the coil 800 to a preset surface facing up, such as flipping it to face up or back up, based on the identification information of the identification device 130. It should be noted that the above-mentioned front and back sides are only two definitions given to distinguish the two end faces of the coil 800. The structures of the front and back sides can be the same or different, and no limitation is made here.
[0090] The aforementioned identification device 130 can be a camera, scanner, etc. Identification marks can be set on the front and / or back of the coil 800 so that the identification device 130 can identify the front and back of the coil 800 by photographing or scanning the identification marks. When the identification device 130 uses a camera, a CCD (charge coupled device) camera can be used.
[0091] like Figure 6As shown, the flipping device 140 includes a fixed bracket 141, a lifting bracket 142, a rotating bracket 143, and a second clamping assembly 144. The fixed bracket 141 is fixedly mounted, and the lifting bracket 142 is slidably mounted on the fixed bracket 141, allowing it to move vertically relative to the fixed bracket 141. The rotating bracket 143 is rotatably mounted on the lifting bracket 142, and the second clamping assembly 144 is mounted on the rotating bracket 143, allowing the rotating bracket 143 to rotate and flip the spool 800. A spool support 145 for placing the spool 800 can be provided next to the flipping device 140. After the first clamping assembly 111 places the spool 800 on the spool support 145, the second clamping assembly 144, driven by the lifting bracket 142, clamps the spool 800 and flips it 180° under the action of the rotating bracket 143, then returns it to the spool support 145, so that the predetermined surface of the spool 800 faces upwards. At this point, the first clamping component 111 clamps the coil 800 again and rotates it 90° before mounting the coil 800 onto the drive shaft 320 of the automatic winding mechanism 300.
[0092] After the empty spool is installed into the automatic winding mechanism 300, the automatic wire laying mechanism 200 and the automatic winding mechanism 300 cooperate to execute step S2. Specifically, the automatic wire laying mechanism 200 detects the bottom hole 804 of the spool 800 and automatically inserts the front end of the wire into the bottom hole 804. The automatic winding mechanism 300 then presses the wire inserted into the bottom hole 804 to prevent the end of the wire from coming out of the bottom hole 804 during the winding process.
[0093] like Figure 7 , Figure 8 As shown, the automatic wire winding mechanism 200 includes a wire feed nozzle 210, a support platform 220, and a support platform drive device. The wire feed nozzle 210 is disposed on the support platform 220 and is used to guide the feeding direction of the wire. The support platform drive device is connected to the support platform 220 and is used to drive the support platform 220 to move, thereby changing the position of the wire feed nozzle 210 relative to the automatic winding mechanism 300.
[0094] like Figure 7 As shown, the support platform 220 is also equipped with a bottom hole detection device 230, a control device (not shown in the figure), and an active wire feeding device 240. The bottom hole detection device 230 can automatically detect the position of the bottom hole 804 of the spool 800 on the automatic winding mechanism 300. When the bottom hole detection device 230 detects the position of the bottom hole 804, the control device can control the support platform 220 to move the wire feeding nozzle 210 so that the wire feeding direction of the wire feeding nozzle 210 is towards the bottom hole 804. The active wire feeding device 240 is used to provide active conveying force to the wire during threading to feed the front end of the wire into the bottom hole 804 of the spool 800.
[0095] There are several ways to implement the bottom hole detection device 230. For example, it can be implemented using a reflective photoelectric sensor. A reflective photoelectric sensor typically includes a transmitter and a receiver. Its working principle is to use the transmitter to emit detection light and the receiver to receive the detection light reflected by the object. By analyzing the state of the reflected detection light, the state of the object can be determined. Reflective photoelectric sensors are simple in structure, easy to use, and have high detection accuracy. Specifically, reflective photoelectric sensors can include infrared reflective photoelectric sensors, laser reflective photoelectric sensors, or ultrasonic reflective photoelectric sensors, etc.
[0096] When a reflective photoelectric sensor is used, its light emission direction can be directed towards the coil 800 on the automatic winding mechanism 300. When the reflective photoelectric sensor is activated, its emitter emits detection light towards the coil 800. As the coil 800 rotates, when the detection light hits the winding roller 801, it is reflected and received by the receiver in the reflective photoelectric sensor. If the receiver continuously receives the reflected light signal, the bottom hole has not been detected. When the detection light passes through the bottom hole 804, it exits, and the receiver in the reflective photoelectric sensor cannot receive the reflected light signal. At this point, the control device determines that the bottom hole detection device 230 has detected the position of the bottom hole 804. The control device then stops the automatic winding mechanism 300 from rotating, and the coil 800 stops at its current position. Since the relative positions of the wire feed nozzle 210 and the reflective photoelectric sensor can be preset, controlling the wire feed nozzle 210 to move to the position of the reflective photoelectric sensor will align the wire feeding direction of the wire feed nozzle 210 with the bottom hole 804.
[0097] like Figure 9As shown, the reflective photoelectric sensor can be set at a first preset position, and the wire feed nozzle 210 can be set at a second preset position, with the light emission direction of the detection light L of the reflective photoelectric sensor parallel to the wire feeding direction of the wire feed nozzle 210. Furthermore, since the automatic loading and unloading mechanism 100 mounts the wire spool 800 onto the automatic winding mechanism 300 in a preset posture, the position of the bottom hole 804 on each wire spool 800 along the axial direction of the wire spool 800 is fixed. Therefore, when setting the initial position (i.e., the first preset position) of the reflective photoelectric sensor, it can be set to correspond to the position of the bottom hole 804 along the axial direction of the wire spool 800, meaning that the position where the detection light illuminates the wire spool 800 is located on the trajectory of the bottom hole 804 as the wire spool 800 rotates. Therefore, when the detection light has not passed through the bottom hole 804, the control device controls the automatic winding mechanism 300 to continuously rotate the coil 800; 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 support platform 220 to move the wire feed nozzle 210 from the second preset position to the first preset position, so that the wire feeding direction of the wire feed nozzle 210 is towards the bottom hole 804. Since the light emission direction of the reflective photoelectric sensor is parallel to the wire feeding direction of the wire feed nozzle 210, the support platform 220 can simply move the wire feed nozzle 210 to the first preset position.
[0098] The hole detection device 230 and the wire feed nozzle 210 can be installed separately or together. When the hole detection device 230 and the wire feed nozzle 210 can be installed separately, they can be independently installed on the support platform 220. Alternatively, for a more compact structure, the hole detection device 230 and the wire feed nozzle 210 can be installed together, such as... Figure 8 As shown, the support platform 220 may be provided with a wire feed nozzle bracket 211 and a bottom hole detection device bracket 231. The wire feed nozzle 210 is disposed on the wire feed nozzle bracket 211; the bottom hole detection device bracket 231 is disposed on one side of the wire feed nozzle bracket 211, and the bottom hole detection device 230 is disposed on the bottom hole detection device bracket 231.
[0099] When the wire feeding nozzle 210 is aligned with the bottom hole 804 of the reel 800 of the automatic winding mechanism 300, the active wire feeding device 240 provides an active conveying force to the wire, thereby feeding the front end of the wire into the bottom hole 804 of the reel 800. Figure 10As shown, the active wire feeding device 240 includes an active wheel 241, a first pressing wheel 242, an active wheel drive 243, and a first pressing wheel 242 drive (not shown in the figure). The active wheel 241 is fixed relative to the support platform 220; the first pressing wheel 242 is arranged opposite to the active wheel 241 in the vertical direction and is movable relative to the active wheel 241 in the vertical direction; the active wheel drive 243 drives the active wheel 241 to rotate. The wire passes between the first pressing wheel 242 and the active wheel 241. The first pressing wheel 242 drive drives the first pressing wheel 242 downward to press the wire. The active wheel drive 243 drives the active wheel 241 to rotate, thereby using the friction between the first pressing wheel 242 and the active wheel 241 to feed the wire forward, so that the front end of the wire passes through the bottom hole 804. To increase the friction between the drive wheel 241 and the wire, the surface of the drive wheel 241 can be provided with anti-slip texture. The anti-slip texture can be a grid or line structure, which can make the conveying force provided by the drive wheel 241 to the wire more stable and prevent slippage during wire feeding.
[0100] When the aforementioned active wire feeding device 240 is installed on the support platform 220, it can be used as follows: Figure 10 The structure shown includes a drive wheel mounting bracket 244 on the support platform 220, with a bearing on the drive wheel mounting bracket 241. The rotation shaft of the drive wheel 241 is rotatably connected to the drive wheel mounting bracket 241 via the bearing, allowing the drive wheel 241 to rotate more smoothly and reducing friction during rotation. A drive component mounting bracket 245 is also provided on the support platform 220, with the drive wheel drive component 243 mounted on the drive component mounting bracket 245. The output shaft of the drive wheel drive component 243 is connected to the drive wheel 241. It should be noted that when the output shaft of the drive wheel drive component 243 and the rotation shaft of the drive wheel 241 have different dimensions, a coupling can be used to connect the output shaft and the rotation shaft.
[0101] The installation method of the first clamping roller 242 on the support platform 220 is as follows: Figure 10 As shown, a clamping wheel fixing frame 246 is provided on the support platform 220, and a slidable clamping wheel moving frame 247 is provided on the clamping wheel fixing frame 246. The first clamping wheel 242 is disposed on the clamping wheel moving frame 247 and is located above the driving wheel 241. The driving component of the first clamping wheel 242 is connected to the clamping wheel moving frame 247 to drive the clamping wheel moving frame 247 to move in the vertical direction.
[0102] The aforementioned drive wheel 243 can be implemented using an electric motor or other mechanisms capable of rotary drive. The aforementioned first clamping wheel 242 drive can be implemented using a cylinder, or other linear drive devices.
[0103] It should be noted that the above-mentioned active wire feeding device 240 only needs to provide active feeding force to the wire when the wire passes through the bottom hole 804 of the empty wire reel. After the wire enters the bottom hole 804 of the wire reel 800, the automatic winding mechanism 300 can drive the empty wire reel to rotate, thereby providing active feeding force to the wire through the automatic winding mechanism 300. At this time, the active wire feeding device 240 can be turned off.
[0104] After the front end of the wire is inserted into the bottom hole 804, to prevent the wire from coming out of the bottom hole 804, the automatic winding mechanism 300 can press the front end of the wire inserted into the bottom hole 804 tightly. For example... Figure 12 , Figure 13 As shown, the automatic winding mechanism 300 includes a fixed base 310, a drive shaft 320, a drive shaft drive component 330, and a wire pressing device. The fixed base 310 is fixedly mounted on the frame 700, the drive shaft 320 is mounted on the fixed base 310, and the drive shaft drive component 330 drives the drive shaft 320 to rotate. The wire pressing device is positioned opposite to the drive shaft 320. When the automatic loading / unloading mechanism 100 installs the wire spool 800 onto the automatic winding mechanism 300, it first places the first end of the center hole 803 of the wire spool 800 onto the drive shaft 320. Then, the automatic loading / unloading mechanism 100 releases the wire spool 800, and the wire pressing device extends from the second end of the center hole 803 into the wire spool 800 to press the wire passing through the bottom hole 804 of the wire spool 800.
[0105] like Figure 12 , Figure 15 As shown, the wire pressing device includes a movable base 340 disposed opposite to the fixed base 310. The movable base 340 is movable along the axial direction of the drive shaft 320. An auxiliary shaft 350 is provided on the movable base 340, and the auxiliary shaft 350 is coaxially disposed with the drive shaft 320. The auxiliary shaft 350 and the movable base 340 are connected by a bearing. The inner ring of the bearing is connected to the auxiliary shaft 350, and the outer ring of the bearing is connected to the bearing seat on the movable base 340. When the drive member drives the drive shaft 320 to rotate, the drive shaft 320 drives the auxiliary shaft 350 and the inner ring of the bearing to rotate through the friction between the drive shaft 320 and the wire reel 800, while the outer ring of the bearing and the bearing seat remain fixed. The auxiliary shaft 350 is connected to an auxiliary shaft moving assembly 360, which can drive the auxiliary shaft 350 to move along the axial direction of the drive shaft 320, so that the auxiliary shaft 350 extends into or moves out of the second end of the central hole 803. Figure 15 , Figure 16As shown, the auxiliary shaft 350 has an axial through hole, and the pressure shaft 370 passes through the axial through hole of the auxiliary shaft 350 and can slide axially relative to the auxiliary shaft 350. The pressure shaft 370 is connected to a pressure shaft drive assembly 380, which can drive the pressure shaft 370 to slide axially along the auxiliary shaft 350 to extend or retract from the auxiliary shaft 350. When the pressure shaft 370 extends out of the auxiliary shaft 350, it presses the wire inserted into the bottom hole 804. It should be noted that the pressure shaft 370 can press the wire onto the drive shaft 320 when pressing the wire.
[0106] There are several ways to implement the aforementioned auxiliary axis moving component 360, as long as it can drive the auxiliary axis 350 to move in a straight line. For example, as... Figure 15 As shown, the auxiliary shaft moving assembly 360 includes an auxiliary shaft guide rail 361 and a screw and nut assembly for driving the movable base 340 to slide along the auxiliary shaft guide rail 361. The auxiliary shaft guide rail 361 is arranged axially along the drive shaft 320, and the movable base 340 is slidably connected to the auxiliary shaft guide rail 361. The screw and nut assembly includes an auxiliary shaft screw 362, an auxiliary shaft nut 350 (not shown in the figure), and an auxiliary shaft motor 363. The auxiliary shaft screw 362 is arranged parallel to the auxiliary shaft guide rail 361. The auxiliary shaft nut 350 is fixed to the movable base 340 and threadedly engaged with the auxiliary shaft screw 362. The auxiliary shaft motor 363 is drively connected to the auxiliary shaft screw 362 to drive the auxiliary shaft screw 362 to rotate. It should be noted that the screw and 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 and rack assembly, a linear cylinder, a linear motor, or other structures. Furthermore, there are multiple ways to connect the auxiliary shaft motor 363 and the auxiliary shaft lead screw 362. For example, the auxiliary shaft motor 363 and the auxiliary shaft lead screw 362 can be directly connected, or they can be indirectly connected through other transmission components. The transmission components can adopt transmission methods such as gear transmission and chain transmission. Figure 15 The structure shown uses a belt drive system with pulleys and belts, and the output shaft of the motor is arranged parallel to the lead screw and arranged in the vertical direction, thus saving horizontal space.
[0107] There are several ways to implement the aforementioned pressure roller drive assembly 380, as long as it can drive the pressure roller 370 to extend and retract relative to the auxiliary shaft 350. In one implementation, such as... Figure 17 , Figure 18As shown, the wire pressing shaft drive assembly 380 includes a wire pressing cylinder 381. The piston rod of the wire pressing cylinder 381 is connected to the wire pressing shaft 370 to drive the wire pressing shaft 370 to slide axially along the auxiliary shaft 350. To keep the wire pressing shaft 370 in a retracted state when not pressing wires, a reset member 382 can also be provided. The reset member 382 is connected to the wire pressing shaft 370, thereby applying a reset force to the wire pressing shaft 370 to maintain it in the retracted state. Specifically, the reset member 382 can be implemented using elastic elements such as springs or sheet springs.
[0108] When the reset element 382 is a spring, the mounting structure of the reset element 382 is as follows: Figure 17 As shown, a spring receiving cavity is provided between the auxiliary shaft 350 and the pressure shaft 370. The outer wall of the pressure shaft 370 has a first positioning part 383, and the inner wall of the auxiliary shaft 350 has a second positioning part 384, located outside the first positioning part 383 (i.e., near the drive shaft 320). The spring receiving cavity is located between the first positioning part 383 and the second positioning part 384, and the spring is located within the spring receiving cavity. One end of the spring abuts against the first positioning part 383, and the other end abuts against the second positioning part 384. The spring is always kept in a compressed state, and the spring's restoring force keeps the pressure shaft 370 in a retracted state. This prevents the pressure shaft 370 from extending out of the auxiliary shaft 350 or falling out of the axial through hole of the auxiliary shaft 350 when not pressure work.
[0109] In order to guide the telescopic movement of the pressure spool 370, such as Figure 18 As shown, the spool drive assembly 380 further includes a spool guide rail 385 and a spool sliding bracket 386. The spool guide rail 385 is disposed on the movable base 340 and extends axially along the drive shaft 320. The spool sliding bracket 386 is slidably engaged with the spool guide rail 385 and connected to the piston rod of the spool cylinder 381. The spool 370 is disposed on the spool sliding bracket 386. Therefore, the spool 370 can be precisely guided by the spool guide rail 385 and the spool sliding bracket 386, resulting in smoother movement of the spool 370.
[0110] Because the wire is small, in order to increase the crimping area and prevent the wire ends from not being crimped, such as... Figure 17 As shown, a wire pressing block 371 can also be provided at the outer end of the wire pressing shaft 370. The outer diameter of the wire pressing block 371 is larger than the outer diameter of the wire pressing shaft 370, thereby increasing the wire pressing area and ensuring the success rate of wire pressing. In addition, the wire pressing block 371 can be made of an elastic material, such as rubber or nylon, to prevent damage to the wire during the wire pressing process.
[0111] Once the front end of the wire passes through the bottom hole 804 and is pressed by the wire pressing shaft 370, step S3 begins, where the wire reel 800 is rotated by the drive shaft 320 of the automatic winding mechanism 300 to wind up the wire.
[0112] There are various ways to implement the drive shaft drive component 330, as long as it can drive the drive shaft 320 to rotate. For example, the drive shaft drive component 330 may include a drive motor for the drive shaft 320 and a transmission assembly. The drive motor for the drive shaft 320 drives the drive shaft 320 to rotate through the transmission assembly. There are various ways to implement the transmission assembly, such as using a belt drive assembly, a chain drive assembly, or a gear drive assembly. The gear drive assembly can use a cylindrical gear set or a bevel gear set. Bevel gears are conical gears, specifically spur bevel gears or spiral bevel gears. Bevel gear sets can be used to transmit power between two intersecting shafts, thereby saving axial arrangement space. Figure 13 In the illustrated scheme, the drive motor of the drive shaft 320 is arranged vertically, and the output shaft of the drive motor 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 drive shaft 320, thereby realizing the power transmission between the output shaft and the drive shaft 320 and saving axial arrangement space.
[0113] There are several ways to make the spool 800 rotate with the drive shaft 320. For example, a key-like transmission structure can be provided between the spool 800 and the drive shaft 320, or between the spool 800 and the first clamping part 321, so that the spool 800 can rotate synchronously with the drive shaft 320. Alternatively, a method can be used... Figure 13 , Figure 15 The structure shown has a first clamping part 321 on the drive shaft 320 and a second clamping part 351 on the auxiliary shaft 350. When it is necessary to install the spool 800 on the drive shaft 320, the wire clamping device can be moved away from the drive shaft 320 to provide sufficient operating space for the spool 800. When the spool 800 is fitted onto the drive shaft 320, the first clamping part 321 abuts against the first end face of the spool 800. At this time, the auxiliary shaft moving assembly 360 can drive the auxiliary shaft 350 to move closer to the drive shaft 320, and the second clamping part 351 gradually approaches the first clamping part 321, eventually abutting against the second end face of the spool 800, thereby clamping the spool 800 along its axial direction. Then, the drive shaft drive 330 is activated to rotate the drive shaft 320 to wind the wire onto the spool 800. The first and second end faces of the aforementioned reel 800 are two end faces arranged along the axial direction of the reel 800, respectively. Figure 4The outer surface of the limiting baffles 802 at both ends of the center plate 800.
[0114] It should be noted that the bottom hole 804 of the coil 800 is positioned to avoid obstructing the drive shaft 320, thus preventing the wire from being blocked by the bottom hole 804 during threading. Since the wire is laid out starting from one end of the winding roller 801, the length of the drive shaft 320 can be set relatively short to avoid the bottom hole 804. However, when the first end of the center hole 803 of the coil 800 is fitted onto the drive shaft 320, the automatic loading and unloading mechanism 100 releases the coil 800. At this time, because the drive shaft 320 is relatively short, only part of the center hole 803 of the coil 800 is fitted onto the drive shaft 320, which may pose a risk of it falling off. To solve the above problem, a coil clamping assembly 390 can be provided on one side of the drive shaft 320. The coil clamping assembly 390 is configured to clamp the coil 800 fitted onto the drive shaft 320 onto the first pressing part 321. Therefore, the reel 800 can be temporarily fixed before the second clamping part 351 clamps it, preventing the reel 800 from falling off the drive shaft 320. When the first clamping part 321 and the second clamping part 351 clamp the reel simultaneously, the reel clamping assembly 390 releases the reel 800.
[0115] like Figure 13 As shown, the spool clamping assembly 390 includes a spool jaw 391 and a clamping cylinder 392. One end of the clamping cylinder 392, away from the spool jaw 391, is hinged to the fixed base 310. The spool jaw 391 is disposed on the fixed base 310 and located on one side of the first pressing part 321. The clamping cylinder 392 is connected to the spool jaw 391 and is configured to drive the spool jaw 391 to open and close to clamp or release the spool 800. Figure 13 As shown, the spool clamp 391 may include a first hinge portion 3911, a second hinge portion 3912, and a clamping portion 3913. The first hinge portion 3911 is hinged to the fixed base 310; the second hinge portion 3912 is hinged to the piston rod of the clamping cylinder 392; the clamping portion 3913 is used to contact the spool 800 to clamp the spool 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 toward the spool 800 to clamp the spool 800; when the piston rod of the clamping cylinder 392 retracts, the piston rod drives the clamping portion 3913 to rotate around the first hinge portion 3911 away from the spool 800 to release the spool 800.
[0116] During the winding process where the automatic winding mechanism 300 drives the spool 800 to rotate and rewind, the automatic wire laying mechanism 200 can be used to lay the wire. The main function of the automatic wire laying mechanism 200 is to guide the wire to change the winding position of the wire on the winding roller 801, thereby making the wire more evenly distributed on the winding roller 801 of the entire spool 800.
[0117] During the winding process, the automatic wire laying mechanism 200 drives the wire feeding nozzle 210 to move for wire laying. During wire laying, in order to make the wire evenly wound on the winding roller 801 of the wire spool 800, the wire can be laid along the axial direction of the winding roller 801. Therefore, one function of the support 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 spool 800 on the automatic winding mechanism 300) to achieve uniform axial laying of the wire on the winding roller 801.
[0118] Furthermore, because the wire contains soft materials, a certain tension is applied to the wire during winding after extrusion to maintain a certain amount of stretch. However, if the tension is too high, the wire can easily be stretched and deformed, resulting in a smaller cross-sectional area and affecting the quality of the wire. When the wire is wound on the reel 800, as the number of winding layers increases, the tension continuously increases because the relative position of the feed nozzle 210 and the reel 800 remains constant. When this tension increases to a certain extent, the cross-sectional area of the wire may fall below the standard value required for the product, and it may even cause the wire to break. To avoid these problems, the distance between the feed nozzle 210 and the reel 800 can be adjusted in real time according to the change in the number of winding layers on the reel 800, thus keeping the wire tension constant. Therefore, another function of the movable base 340 is to move the wire feed nozzle 210 along a second horizontal direction (a horizontal direction perpendicular to the axis of the wire reel 800) to adjust the distance between the wire feed nozzle 210 and the wire reel 800, and to move the wire feed nozzle 210 vertically to adjust the height of the wire feed nozzle 210 relative to the wire reel 800. This allows for adjustment of the relative position of the wire feed nozzle 210 and the wire reel 800 in two dimensions to accommodate changes in the number of wire layers wound on the wire reel 800, thus maintaining the wire tension within a preset range. For example, during winding, as the number of wire layers increases, the platform drive device moves the platform away from the wire reel, thereby keeping the wire length between the wire feed nozzle and the wire reel within a preset range. This prevents the wire tension from continuously increasing, ensuring that the wire tension remains within a preset range during winding.
[0119] It should be noted that the length of the wire between the wire feed nozzle and the wire reel refers to the length of the wire after the wire exit end of the wire feed nozzle and before it is wound onto the winding roller. The distance by which the support platform drive device moves the support platform away from the wire reel can be preset according to the number of layers of wire wound on the wire reel. For example, it can be preset that for each additional layer of winding, the support platform moves a certain distance away from the wire reel.
[0120] In addition to adjusting the distance between the wire feed nozzle and the spool, the tension of the wire can also be maintained by adjusting the vertical position of the wire feed nozzle. For example, if the point of tangency between the wire and the winding roller is located at the upper edge of the winding roller, moving the wire feed nozzle upward will increase the length of the wire between the wire feed nozzle and the spool, thereby reducing the tension of the wire. Conversely, if the point of tangency between the wire and the winding roller is located at the lower edge of the winding roller, moving the wire feed nozzle downward will increase the length of the wire between the wire feed nozzle and the spool, similarly reducing the tension of the wire.
[0121] To achieve the aforementioned movement of the support platform 220, such as Figure 7 , Figure 9 As shown, the carrier platform drive device includes an X-axis moving component 250, a Y-axis moving component 260, and a Z-axis moving component 270. The X-axis moving component 250 is configured to drive the carrier platform 220 to move along a first horizontal direction (i.e., the axial direction of the reel 800 on the automatic winding mechanism 300) to adjust the position of the wire feed nozzle 210 along the axial direction of the reel 800. For example, during the wire winding process, the X-axis moving component 250 drives the carrier platform 220 to reciprocate along the first horizontal direction, allowing the wire to be wound in multiple layers on the winding rollers of the reel. Furthermore, a limit sensor can be used to control the range of movement of the carrier platform 220 along the first horizontal direction, adapting this range to the length of the winding rollers on the reel. When the limit sensor has a counting function, it can also detect the number of times the carrier platform 220 reciprocates along the first horizontal direction, thereby calculating the number of winding layers of wire on the reel, in order to control the distance between the wire feed nozzle 210 and the reel.
[0122] The Y-axis moving component 260 is configured to move the support platform 220 along a second horizontal direction to adjust the distance between the wire feed nozzle 210 and the wire reel 800. This second horizontal direction is perpendicular to the first horizontal direction. This allows for real-time adjustment of the distance between the wire feed nozzle 210 and the wire reel, ensuring that the wire tension remains within a preset range during winding.
[0123] The Z-axis moving assembly 270 is configured to move the support platform 220 vertically to adjust the height of the wire feed nozzle 210 relative to the wire spool 800. Thus, the tension of the wire can be maintained by adjusting the position of the wire feed nozzle in the vertical direction.
[0124] It also has an X-axis moving component 250, a Y-axis moving component 260 and a Z-axis moving component 270, which can realize the movement of the wire feeding nozzle 210 in the X, Y and Z directions, thereby enabling the wire to be laid evenly in the radial direction on the winding roller 801 and maintaining the tension of the wire during the laying process.
[0125] When specifically setting the relative positions of the support platform 220, X-axis moving component 250, Y-axis moving component 260, and Z-axis moving component 270, the X-axis moving component 250 can be connected to the support platform 220 to move the support platform 220 along the first horizontal direction; the Z-axis moving component 270 can be connected to the X-axis moving component 250 to raise and lower the X-axis moving component 250 and the support platform 220; the Y-axis moving component 260 can be connected to the Z-axis moving component 270 to move the Z-axis moving component 270, the X-axis moving component 250, and the support platform 220 along the second horizontal direction. This allows the wire feed nozzle 210 to move in the X, Y, and Z directions. It should be noted that, in addition to the embodiments described above, the mutual driving relationships of the X-axis moving component 250, the Y-axis moving component 260, and the Z-axis moving component 270 can be arbitrarily arranged and combined. For example, the Y-axis moving component 260 can be directly connected to the support platform 220, the X-axis moving component 250 can be connected to the Y-axis moving component 260, and the Z-axis moving component 270 can be connected to the X-axis moving component 250. Alternatively, the Z-axis moving component 270 can be directly connected to the support platform 220, the X-axis moving component 250 can be connected to the Z-axis moving component 270, and the Y-axis moving component 260 can be connected to the X-axis moving component 250.
[0126] The X-axis moving component 250, Y-axis moving component 260, and Z-axis moving component 270 can be implemented in various ways, as long as linear drive can be achieved. For example, cylinder drive, linear motor drive, motor with rack and pinion transmission, motor with lead screw and nut transmission, and linear module drive can be used. The linear module, also called a linear slide, is an automation upgrade unit following linear guides, linear motion modules, and ball screw linear transmission mechanisms. Linear motion of the load can be achieved through the combination of various units, making automation of light loads more flexible and positioning more precise. Commonly used linear modules include synchronous belt type, ball screw type, and linear motor type.
[0127] Figure 9 In the scheme shown, the X-axis moving component 250, the Y-axis moving component 260, and the Z-axis moving component 270 all adopt a scheme of motor and lead screw and nut transmission to achieve linear drive.
[0128] like Figure 9 As shown, the Y-axis moving assembly 260 includes a Y-axis guide rail 261, a Y-axis moving platform 262, a Y-axis lead screw 263, a Y-axis nut (not shown), and a Y-axis motor 264. The Y-axis guide rail 261 is fixed to the frame 700, and the Y-axis moving platform 262 is slidably engaged with the Y-axis guide rail 261. The X-axis moving assembly 250 and the Z-axis moving assembly 270 are both mounted on the Y-axis moving platform 262. The Y-axis lead screw 263 is mounted on the frame 700 and extends along the second horizontal direction. The Y-axis nut is fixed to the Y-axis moving platform 262 and engages with the Y-axis lead screw 263. The Y-axis motor 264 is connected to the Y-axis lead screw 263 to drive the Y-axis lead screw 263 to rotate. When the Y-axis lead screw 263 rotates, it can drive the Y-axis moving platform 262 to move along the second horizontal direction through the Y-axis nut, thereby driving the X-axis moving assembly 250 and the Z-axis moving assembly 270 to move along the second horizontal direction, and further driving the wire feed nozzle 210 on the bearing platform 220 to move along the second horizontal direction.
[0129] like Figure 7 As shown, the Z-axis moving assembly 270 includes a lifting platform 271, a vertical guide 272, a Z-axis lead screw 273, a Z-axis nut (not shown), and a Z-axis motor 274. The X-axis moving assembly 250 is mounted on the lifting platform 271. The vertical guide 272 is mounted on the Y-axis moving platform 262 and slidably engages with the lifting platform 271 to guide the lifting platform 271 to move vertically. The Z-axis lead screw 273 is vertically aligned. The Z-axis nut is fixed to the lifting platform 271 and threadedly engages with the Z-axis lead screw 273. The Z-axis motor 274 is mounted on the Y-axis moving platform 262 and connected to the Z-axis lead screw 273 to drive the Z-axis lead screw 273 to rotate. When the Z-axis lead screw 273 rotates, it drives the Z-axis nut and the lifting platform 271 to move vertically, thereby driving the X-axis moving assembly 250 and the support platform 220 to move vertically.
[0130] like Figure 7 As shown, the X-axis moving assembly 250 includes an X-axis motor (not shown), an X-axis guide rail 251 extending along a first horizontal direction, and an X-axis lead screw (not shown). The X-axis guide rail 251 is mounted on the lifting platform 271. An X-axis nut and a guide are provided below the support platform 220. The X-axis nut and the X-axis lead screw are threaded together, and the guide and the X-axis guide rail 251 are slidably connected. The output shaft of the X-axis motor is connected to the X-axis lead screw to drive the X-axis lead screw to rotate. When the X-axis lead screw rotates, it drives the X-axis nut and the support platform 220 to move along the X-axis guide rail 251 through the thread.
[0131] In order to smoothly introduce the wire produced on the production line into the wire feed nozzle 210, a wire guide assembly 280 can be provided on the support platform 220. The wire guide assembly 280 can guide the wire into the wire feed nozzle 210 along the extension direction of the wire feed nozzle 210, thereby avoiding bending of the wire when entering the wire feed nozzle 210.
[0132] like Figure 9 As shown, the wire guiding assembly 280 may include a first guiding assembly 281 and a second guiding assembly 282 sequentially arranged along the second horizontal direction. The first guiding assembly 281 is configured to restrict the position of the wire in the first horizontal direction, aligning the wire with the wire feed nozzle 210 in the first horizontal direction. The second guiding assembly 282 is disposed downstream of the first guiding assembly 281 and is configured to restrict the position of the wire in the vertical direction, aligning the wire with the wire feed nozzle 210 in the vertical direction. Thus, the position of the wire can be restricted in both the first horizontal and vertical directions to align the wire's feeding direction with the inlet of the wire feed nozzle 210, preventing the wire from bending when entering the wire feed nozzle 210.
[0133] The specific structure of the first guiding component 281 can be as follows: Figure 9 As shown, the first guiding assembly 281 includes a first guide roller 2811 and a second guide roller 2812. Both the first guide roller 2811 and the second guide roller 2812 can be arranged along the vertical direction, and the first guide roller 2811 and the second guide roller 2812 are spaced apart along the first horizontal direction. The wire can 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 setting the first guide roller 2811 and the second guide roller 2812, the gap between the first guide roller 2811 and the second guide roller 2812 can be aligned with the inlet of the wire feed nozzle 210, thereby achieving alignment of the wire with the wire feed nozzle 210 in the first horizontal direction.
[0134] The specific structure of the second boot component 282 can be as follows: Figure 11As shown, the second guide assembly 282 includes an upper guide wheel group 2821 and a lower guide wheel group 2822. The upper guide wheel group 2821 includes a plurality of upper guide wheels arranged along the second horizontal direction. The lower guide wheel group 2822 is disposed below the upper guide wheel group 2821 and includes a plurality of lower guide wheels arranged along the second horizontal direction. The wire after passing through the first guide assembly 281 can be passed between the upper guide wheel group 2821 and the lower guide wheel group 2822, thereby restricting the position of the wire in the vertical direction. When setting the upper guide wheel group 2821 and the lower guide wheel group 2822, the gap between them can be aligned with the inlet of the wire feed nozzle 210, thereby achieving alignment of the wire with the wire feed nozzle 210 in the vertical direction.
[0135] When setting the relative positions of multiple upper and lower guide wheels, to ensure sufficient contact between the upper and lower guide wheels and the wire, the upper and lower guide wheels can be staggered vertically. That is, the upper and lower guide wheels are not aligned vertically, and the projection of an upper guide wheel onto the plane of a lower guide wheel lies between two adjacent lower guide wheels. Therefore, when the wire passes between the upper guide wheel group 2821 and the lower guide wheel group 2822, the wire has a larger contact area with both the upper and lower guide wheels, resulting in more uniform force distribution on the wire during transmission.
[0136] To accommodate wires of different diameters, one of the upper guide wheel assembly 2821 and the lower guide wheel assembly 2822 can be configured as a movable structure. For example, the lower guide wheel assembly 2822 can be fixed relative to the support platform 220, while the upper guide wheel assembly 2821 can be moved vertically relative to the support platform 220. Thus, during initial wire threading, the upper guide wheel assembly 2821 can be lifted upwards, and after the wire passes between the upper guide wheel assembly 2821 and the lower guide wheel assembly 2822, the upper guide wheel assembly 2821 can be lowered to hold the wire in place. This allows wires of different diameters to pass between the upper guide wheel assembly 2821 and the lower guide wheel assembly 2822, improving the equipment's versatility. Alternatively, the upper guide wheel assembly 2821 can be fixed relative to the support platform 220, while the lower guide wheel assembly 2822 can be moved vertically relative to the support platform 220. Alternatively, both the upper guide wheel assembly 2821 and the lower guide wheel assembly 2822 can be configured to move relative to the support platform 220 in the vertical direction.
[0137] like Figure 11As shown, a guide wheel fixing frame 2823 and a guide wheel moving frame 2824 can be provided on the support platform 220. The guide wheel fixing frame 2823 is fixed relative to the support platform 220, and the lower guide wheel assembly 2822 is fixedly mounted on the guide wheel fixing frame 2823. The guide wheel moving frame 2824 is movably mounted on the guide wheel fixing frame 2823 and located above the lower guide wheel assembly 2822. The guide wheel moving frame 2824 can move vertically relative to the guide wheel fixing frame 2823, and the upper guide wheel assembly 2821 is mounted on the guide wheel moving frame 2824. The guide wheel moving frame 2824 is also connected to a moving frame drive component, which drives the guide wheel moving frame 2824 to move vertically.
[0138] There are various implementation schemes for the moving frame drive components, such as cylinder drive, linear motor drive, motor combined with gear and rack transmission, motor combined with lead screw and nut transmission, etc. Figure 11 The illustrated solution employs a cylinder drive. The moving frame drive component includes a moving frame guide rail 2825 and a moving frame drive cylinder 2826. The moving frame guide rail 2825 is vertically mounted on the guide wheel fixing frame 2823 and slidably engages with the guide wheel moving frame 2824. The moving frame drive cylinder 2826 is connected to the guide wheel moving frame 2824 to drive the guide wheel moving frame 2824 to move vertically. The cylinder drive has fewer components, is easy to assemble, and saves space.
[0139] To precisely adjust the wire feeding direction, at least one lower guide wheel in the lower guide wheel assembly 2822 can be connected to the guide wheel fixing frame 2823 via an adjustable structure, thereby making the vertical position of the lower guide wheel adjustable. For example, the lower guide wheels at both ends of the lower guide wheel assembly 2822 can be connected to the guide wheel fixing frame 2823 via the adjustable structure. This allows for precise adjustment of the wire feeding direction. Specifically, the adjustable structure includes a guide groove on the guide wheel fixing frame 2823, a slider on the lower guide wheel, and a fastener. The slider slides into the guide groove, and the fastener can switch between a locked state and an unlocked state. When the fastener is in the locked state, it locks the lower guide wheel to the guide groove. When the fastener is in the unlocked state, the lower guide wheel can slide relative to the guide groove. Specifically, the fastener can be a screw, pin, or similar structure.
[0140] In order to accurately measure the winding length of the wire during the winding process, a metering component 290 can be set up. The metering component 290 can measure the length of the wire wound onto the wire reel 800, so as to facilitate accurate statistics on the wire produced on the production line.
[0141] like Figure 11 As shown, the metering component 290 may specifically include a metering roller 291, a second clamping roller 292, and a rotation detection element (not shown in the figure). The metering roller 291 is disposed on the transmission path of the wire. The second clamping roller 292 is disposed opposite to the metering roller 291 in the vertical direction and is movable relative to the metering roller 291 in the vertical direction. The rotation detection element is connected to the metering roller 291 to detect the number of rotations of the metering roller 291. The wire can pass between the metering roller 291 and the second clamping roller 292. When the metering roller 291 and the second clamping roller 292 clamp the wire, the frictional force of the wire conveying forward can drive the metering roller 291 to rotate. Since the metering roller 291 is connected to the rotation detection element, the length of the wire passing through the metering roller 291 can be calculated by the number of rotations of the metering roller 291 detected by the rotation detection element. The rotation detection element can be a rotary encoder or other detection instrument.
[0142] To achieve the vertical movement of the second pressure roller 292, a separate drive unit can be used to drive the second pressure roller 292, for example, a separate cylinder can be used to drive its vertical movement. Additionally, as... Figure 11 As shown, the second pressing wheel 292 and the upper guide wheel assembly 2821 can also be arranged together, for example, both on the guide wheel moving frame 2824, so that the second pressing wheel 292 and the upper guide wheel assembly 2821 are driven by the moving frame drive component, thereby reducing the number of drive components, saving equipment costs and reducing the space occupied. In a specific arrangement, the metering roller 291 can be arranged on the guide wheel fixing frame 2823 and along the second horizontal direction with the plurality of lower guide wheels, and the second pressing wheel 292 can be arranged on the guide wheel moving frame 2824 and along the second horizontal direction with the plurality of upper guide wheels.
[0143] After the wire is wound onto the reel 800, step S4 can be performed, which involves cutting the wire and securing it to the reel 800 to complete the tailing process. It should be noted that the term "tailing line" can be understood as the end of the wire wound on the reel 800. After the wire is wound, this end needs to be secured or knotted to the reel 800 to prevent the wire wound on the reel 800 from loosening. The term "tailing line" refers to knotting the tail line; the tailing process is the process of securing or knotting the end of the wire to the reel 800.
[0144] The above-mentioned finishing line process can be achieved by an automatic finishing line mechanism 400. For example... Figure 19 , Figure 20As shown, the automatic end-of-line mechanism 400 can be mounted on the automatic winding mechanism 300. The automatic end-of-line mechanism 400 includes a wire-cutting module 410 and a wire-threading module. The wire-cutting module 410 automatically cuts off the end of the wire that is not wound onto the spool 800 after the wire has been wound and coiled into the spool 800, forming the end of the wire. The wire-threading module automatically threades the end of the wire through the threading hole of the spool 800 and secures it.
[0145] It should be noted that the above-mentioned automatic end-of-line mechanism 400 being disposed on the automatic winding mechanism 300 includes both the automatic end-of-line mechanism 400 being directly installed on the automatic winding mechanism 300 and the automatic end-of-line mechanism 400 being located near the automatic winding mechanism 300 but not directly installed on the automatic winding mechanism 300.
[0146] The wire cutting module 410 may include automatic scissors and a scissor drive device. The automatic scissors can automatically open and close to cut the wire; while the scissor drive device can move the automatic scissors to the wire cutting position. Specifically, the automatic scissors may be pneumatic or electric scissors.
[0147] To more securely fix the end of the wire to the reel 800, the reel 800 typically has two through holes: a first through hole 805 and a second through hole 806. The wire end is then passed through the first through hole 805 and the second through hole 806 in sequence and pulled taut to complete the relative fixation between the wire and the reel 800. Figure 20 As shown, the first threading hole 805 and the second threading hole 806 can be located on the same side of the coil 800. When threading the wire, the tail end can first pass through the first threading hole 805, then be rotated before being threaded through the second threading hole 806, thus securing the wire relative to the coil 800. To achieve this process, the threading module includes a wire feeding module 420 and a wire guide mechanism 430. The wire feeding module 420 automatically threads the tail end of the wire into the first threading hole 805 of the coil 800. The wire guide mechanism 430 is configured to guide the tail end out of the second threading hole 806 after it has passed through the first threading hole 805.
[0148] The aforementioned automatic end-of-line mechanism 400 incorporates a wire guide mechanism 430. This mechanism guides the tail end through the first threading hole 805 and out through the second threading hole 806. Therefore, during threading, the wire feeding module 420 only needs to continuously feed the wire into the first threading hole 805. After entering the first threading hole 805, the wire changes direction under the action of the wire guide mechanism 430 and gradually exits the second threading hole 806 as the wire feeding module 420 continues to feed the wire. Thus, the wire feeding module 420 can secure the wire to the reel 800 without complex threading operations, making it more convenient to implement.
[0149] The wire guide mechanism 430 may include a wire guide groove assembly and a wire guide groove drive (not shown in the figure). Figure 20 As shown, the wire guide assembly includes a substrate 431 and a wire groove 432 disposed on a first surface of the substrate 431. The first end of the wire groove 432 faces the first through hole 805, and the second end of the wire groove 432 faces the second through hole 806. Thus, when the tail end of the wire passes through the first through hole 805, it can enter the wire groove 432 from the first end of the wire groove 432. The wire, relying on its own flexibility, can bend and turn under the guidance of the wire groove 432, gradually exiting from the second end of the wire groove 432 and passing through the second through hole 806.
[0150] It should be noted that the first end of the aforementioned wire groove 432 faces the first wire hole 805. This can be either a direct contact and connection between the first end of the wire groove 432 and the first wire hole 805, or a situation where the first end of the wire groove 432 is opposite to the first wire hole 805 with a certain gap. Similarly, the second end of the aforementioned wire groove 432 faces the second wire hole 806. This can be either a direct contact and connection between the second end of the wire groove 432 and the second wire hole 806, or a situation where the second end of the wire groove 432 is opposite to the second wire hole 806 with a certain gap.
[0151] The aforementioned wire groove drive is used to move the wire groove assembly towards or away from the spool 80011. Thus, when a finishing wire process is required, the wire groove drive can move the wire groove assembly towards the spool 800, connecting both ends of the wire groove assembly to the first threading hole 805 and the second threading hole 806, respectively. After the finishing wire process is completed, the wire groove drive can move the wire groove assembly away from the spool 800, disengaging the wire groove assembly from the wire, thereby facilitating the removal of the completed spool 800.
[0152] It should be noted that the aforementioned wire groove drive can be any device capable of linear drive, such as a cylinder, linear motor, or rotary motor combined with a linear transmission mechanism.
[0153] The main function of the wire feeding module 420 is to clamp the wire and feed it into the first threading hole 805. The wire feeding module 420 may include a wire clamping module and a wire clamping displacement module. The wire clamping module is used to clamp the portion of the wire near its tail end. The wire clamping displacement module can drive the wire clamping module to move closer to or away from the first threading hole 805, so as to pass the tail end of the wire into the first threading hole 805 of the wire reel 800.
[0154] like Figure 20As shown, the wire clamping module may include a first wire clamping module 421 and a second wire clamping module 422. The first wire clamping module 421 is used to clamp a first portion of the wire, and the second wire clamping module 422 is 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 can drive the first wire clamping module 421 and the second wire clamping module 422 to move as a whole to pass the tail end of the wire through the first threading hole 805. After 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 module 422 to move back and forth in the direction of approaching and moving away from the first threading hole 805 (during this process, the second wire clamping module 422 releases the wire when it is closest to the first threading hole 805, and clamps the wire again when it is furthest away from the first threading hole 805, that is, to perform the threading action). The tail end of the wire is passed through the wire guide mechanism 430 and out of the second wire hole 806.
[0155] The wire feeding module 420 may also include a wire clamping module lifting device, which is used to lift the first wire clamping module 421 and the second wire clamping module 422. This allows the wire clamping modules to be moved to a suitable position to clamp the wire when the wire finishing process is required. The wire clamping module lifting device can be implemented using a cylinder, linear motor, or rotary motor in conjunction with a linear transmission mechanism.
[0156] After the end of the wire passes through the first threading hole 805 and the second threading hole 806 in sequence, the end of the wire can be tightened to prevent it from coming off through the first threading hole 805 and the second threading hole 806. To automate the tightening process, such as... Figure 20 As shown, the threading module may also include a wire tensioning module 440, which can automatically tighten the tail end of the wire that has passed through the second threading hole 806.
[0157] The wire tensioning module 440 may include tensioning jaws and a tensioning drive. The tensioning jaws are positioned on the wire exit side of the second wire threading hole 806 to grip the tail end of the wire exiting the second wire threading hole 806. The tensioning drive can move the tensioning jaws closer to or further away from the second wire threading hole 806 to automatically tension the tail end of the wire. The tensioning drive can be a commonly used drive component such as a cylinder or motor, which will not be described in detail here.
[0158] It should be noted that the aforementioned front end of the wire refers to the front end of the wire output from the production line when the wire is not rewound; the tail end of the wire refers to the end formed on the rewound wire after it has been rewound on a wire spool 800 and the wire on the production line has been cut off.
[0159] Once the wire on a spool 800 is wound up, the spool 800 can be removed from the automatic winding mechanism 300 and weighed and sorted. The purpose is to separate unqualified full spools that do not meet the weight requirements from qualified full spools that do meet the weight requirements, thus ensuring product standardization. This process can be automated using an automatic finished product weighing mechanism 500. Figure 2 As shown, the automatic finished product weighing mechanism 500 may include a finished product picking device 510 and a weighing device 520. The finished product picking device 510 is used to remove the full spool of yarn from the automatic winding mechanism 300 and transport it to the weighing station. The weighing device 520 can move to the weighing station and can automatically receive the spool of yarn 800 transported by the finished product picking device 510, thereby automatically weighing the spool of yarn 800.
[0160] like Figure 21 As shown, the finished product handling device 510 includes a finished product gripper 511, a gripper rotation assembly 512, and a gripper movement assembly 513. The finished product gripper 511 grips the spool 800, and the gripper rotation assembly 512 rotates the gripper 511, thereby turning the vertically positioned spool 800 into a horizontal position. A horizontally positioned spool 800 is more stable and less prone to rolling when placed on the weighing device 520. The gripper movement assembly 513 moves the gripper rotation assembly 512 and the finished product gripper 511 to the weighing station, whereby the spool 800 is placed on the weighing device 520 for weighing. The gripper rotation assembly 512 can be implemented using a rotary cylinder or a motor; the gripper movement assembly 513 can be implemented using... Figure 21 The guide rail and lead screw nut structure shown can be used to achieve the same result, but other linear drive structures can also be used.
[0161] The structure of the weighing device 520 is as follows: Figure 22As shown, the weighing device 520 is located at the weighing station and is movable as a whole. After the finished product receiving device 510 transports the full reel to the weighing station, the weighing device 520 can move along the bottom guide rail 521 to a position below the finished product receiving device 510. Specifically, the weighing device 520 can be driven by linear drive devices such as linear cylinders, motors with lead screws and nuts, or motors with gears and racks. The weighing device 520 also includes a receiving platform 522, a receiving drive component 523, and a weighing platform 524. Among them, the weighing platform 524 is fixed relative to the frame 700; the receiving drive component 523 is used to drive the receiving platform 522 to move in the vertical direction. When the finished product receiving device 510 transports the full reel of wire to the weighing station, the receiving drive unit 523 drives the receiving platform 522 upward to move above the weighing platform 524. At this time, the finished product receiving device 510 places the full reel of wire on the receiving platform 522. Then, the receiving drive unit 523 drives the receiving platform 522 downward until the receiving platform 522 places the full reel of wire on the weighing platform 524. The weighing platform 524 is connected to a weighing sensor, so the full reel of wire can be automatically weighed.
[0162] After the coil 800 is weighed, the automatic loading and unloading mechanism 100 loads the coil 800 that has been wound up and has the correct weight into the turnover cart 600, and loads the coil 800 that has been wound up and has the incorrect weight into the defective product storage bin 701.
[0163] It should be noted that since the turnover cart itself contains empty wire reels, full wire reels cannot be placed into a storage bin until the reels in that bin are emptied. Therefore, a transfer bin 702 can be installed on the frame of the wire winding equipment to temporarily store full wire reels when the turnover cart cannot accommodate them. Alternatively, if space permits, two turnover carts can be installed, one for empty wire reels and the other for full wire reels.
