Description

Technical Field

[0001] The present invention relates to the technical field of consumable tray loading, and in particular to a consumable tray loading and threading mechanism and a consumable tray loading and threading method. Background Art

[0002] FDM 3D printers use linear consumables for 3D printing. In the prior art, most manufacturers configure winding machines to neatly wind the consumables and load them onto reels. Conventional winding and loading machines are semi-automatic. Specifically, the initial end of the consumables needs to be manually inserted into the reel jack by the operator to fix the initial section of the consumables on the reel. In addition, after the winding is completed, the operator needs to manually insert the end of the wire into the two threading holes of the reel in a back-and-forth manner to fix the end of the consumables on the reel. Therefore, the winding and loading efficiency is not high enough. Among them, the applicant retrieved application number 2021230 Patent No. 143315 discloses a mechanism for automatically threading the end of a 3D printed wire reel. It attempts to disclose a device that can simply and effectively thread the wire through two wire reel holes in a limited space after the wire is wound, and then tighten the wire. The device mechanism has a short operation cycle, which can effectively save production time. The operation is simple and convenient. However, the patent document does not clearly describe how to thread the wire through the two reel holes to simulate manual threading. The applicant believes that it has the intention to solve the problem of threading and fixing, but has not yet completed a complete technical solution. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a consumables reeling and threading mechanism, which can mechanize the fixation of the thread ends during the winding and reeling process, thereby greatly improving the efficiency of the reel winding and reeling.

[0004] The technical solution adopted by the present invention is as follows: one aspect of the present invention is to provide a consumables reel loading and threading mechanism, which includes a reel rotating and winding mechanism, a consumables thread head threading mechanism and a consumables thread tail threading mechanism;

[0005] The bobbin rotating winding mechanism includes a chuck, a barrel disposed in the middle of the chuck and used to mount the bobbin, a rotation driver for driving the chuck to rotate, a linear guide rail, a slide seat sliding on the linear guide rail, and a slide seat driver for driving the slide seat to slide on the linear guide rail, wherein the rotation driver is mounted on the slide seat;

[0006] The wire reel includes a central tube and baffles located on both sides of the central tube. The central tube is provided with a wire head through-hole, and the baffles are provided with two wire tail through-holes. The length of the clamping tube is shorter than that of the central tube.

[0007] The consumable thread threading mechanism includes an outlet head for outputting consumables and a pre-pressed plug body assembly arranged in front of the cartridge, the outlet head is located on the upper side of the cartridge, and the thread head perforation of the wire reel can be connected with the consumables output by the outlet head; the pre-pressed plug body assembly includes a first mounting seat and a pushing rod arranged on the first mounting seat, the end of the pushing rod is provided with a docking plug body for relative rotation, or the end of the pushing rod is provided with a rotating connector for relative rotation and the rotating connector is fixedly connected to the docking plug body, the docking plug body is adapted to the interior of the center tube and is positively opposite to the cartridge;

[0008] The consumable wire tail threading mechanism includes an air shear located in front of the wire outlet head, a first rotating chuck located in front of the air shear and a second rotating chuck located on one side of the first rotating chuck. The first rotating chuck and the second rotating chuck are respectively located on both sides of the chuck. A transversely movable wire pulling chuck cylinder is spaced apart on the side of the second rotating chuck away from the first rotating chuck. The consumable can be cut by the air shear and form a consumable end. The first rotating chuck and the second rotating chuck can clamp and rotate in steps to allow the consumable end to pass through the two wire tail perforations in sequence.

[0009] In the above scheme, the chuck can be used to install an unloaded wire reel. Since the chuck is shorter than the center tube, when the wire reel is installed on the chuck, a part of the inside of the center tube is not covered by the chuck, and the wire end perforation is located on the uncovered part of the center tube, that is, the wire end perforation is located on the center tube close to the baffle. On the other hand, when the wire reel is loaded into the cartridge, the wire outlet and the wire end perforation can be corresponding, that is, after the consumable is conveyed out from the wire outlet, it can be inserted into the wire end perforation; the wire end of the consumable, that is, the initial end, can be fixed by the pre-pressed plug assembly after being inserted into the wire end perforation, specifically: the push rod can insert the docking plug into the inner cavity of the center tube, and the docking plug can rotate relative to the push rod, wherein the rotating connecting part is a ball bearing connection structure; the part of the consumable inserted into the wire end perforation will enter the interior of the center tube and can be squeezed and stuck by the docking plug after being inserted into the center tube. When the end of the consumable is stuck, it is clamped between the docking plug and the inner wall of the center tube, so that the starting end of the consumable can be fixed on the wire reel.On the other hand, the chuck and the cartridge can be driven to rotate by the rotary driver, and the chuck and the cartridge can be moved linearly synchronously with the slide seat driven by the slide seat driver, so the cartridge can drive the wire reel to rotate and move laterally, so when combined with the outlet head that can convey consumables, the consumables can be neatly wound and loaded onto the wire reel; on the other hand, after the winding and loading are completed, the consumables need to be cut off, so the present invention is equipped with a consumable wire tail threading mechanism, and the air shear cuts the consumable wire body and threads the consumable end connected to the wire reel. The purpose is to fix the consumables on the reel in the form of a wire to prevent the consumables on the reel from becoming loose; the end of the consumable is fixed on the reel in the form of a back and forth threading, specifically, the first rotating chuck can clamp the consumables, and then the air shear can cut the consumables coming out of the wire outlet, so that the consumables wound on the reel form a consumable end and the consumable end is clamped by the first rotating chuck, and then the first rotating chuck rotates toward the direction of the second rotating chuck, so that the end of the consumable end can be passed toward a wire tail hole on the baffle, wherein the chuck The outer diameter is smaller than that of the baffle, so the wire end perforation is exposed outside the chuck. In addition, the sliding seat can be used to move the wire reel so that the end of the consumable can be inserted into the wire end perforation on the wire reel that is coming over. At this time, the end of the consumable passes through between the two baffles to the outside of one baffle. At this time, the wire pulling chuck cylinder can clamp and pull the end of the consumable to make the end of the consumable straight and make the end of the consumable extend as far as possible to the outside of the baffle. Then, the second rotating chuck can clamp the end of the consumable and rotate it to make it The filament end is forced toward the other end of the thread through the hole, while the pneumatic cylinder of the wire chuck releases the filament. During this process, the chuck is driven to rotate the spool to an angle, positioning the filament end directly opposite the thread hole. The sled then moves, similarly to the sled, allowing the filament end to fit neatly into the second thread hole on the approaching spool. The filament end has now been threaded back and forth between the two thread holes and secured to the spool, mimicking the manual threading process. The sled, after moving back and forth with the first and second rotating chucks, returns to its initial position, a clever design. This threading mechanism mechanically replicates the manual threading process, replacing manual labor and improving efficiency. Once threaded, the filament end is securely fastened to the spool, preventing it from loosening. This allows for automated threading during the winding and loading process, significantly improving efficiency.

[0010] In one embodiment, it includes a wire reel angle adjustment mechanism and a loading robot for picking up and placing the wire reel;

[0011] The reel angle adjustment mechanism includes a limited rotating clamp, an optical fiber sensor, and an optical fiber sensor mounting base for mounting the optical fiber sensor. The optical fiber sensor mounting base is provided with a positioning slide using a screw drive, and the optical fiber sensor is mounted on the positioning slide. The outer side surface of the baffle of the reel is provided with a calibration position, and the optical fiber sensor cooperates with the calibration position.

[0012] The loading robot includes a material picking and placing clamping claw, and the material picking and placing clamping claw is adapted to the central tube of the wire drum;

[0013] The unloaded wire drum is transferred by the loading robot and mounted on the cartridge after the placement angle is adjusted by the wire drum angle adjustment mechanism.

[0014] In the above scheme, the reel angle adjustment mechanism positions the reel at a preset angle. An empty reel can be transferred by the loading robot to the reel rotating and winding mechanism and mounted on the chuck. Because the reel's angle is preset, the outlet and the perforation are aligned when the reel is loaded into the chuck. This means that consumables can be directly inserted into the perforation after being fed from the outlet. Furthermore, the limited rotary gripper is a combination of an SMC MHS3 air gripper and a rotary cylinder. The limited rotary gripper clamps the reel's center tube from bottom to top. The fiber optic sensor includes a PRS-410 fiber amplifier line probe. When the reel angle adjustment mechanism is in use, the limited rotary gripper rotates the reel it holds. During rotation, the reel's calibration position aligns with the fiber optic sensor, causing the limited rotary gripper to stop, thereby positioning the reel at the preset angle and facilitating subsequent winding. The distance between the calibration notch and the position-limiting rotating gripper varies for reels of different sizes. Therefore, to accommodate different reels, the position of the fiber optic sensor is adjustable via a positioning slide. Furthermore, the pick-and-place gripper is a Japanese SMC MHS3 air gripper with a finger cylinder.

[0015] In one embodiment, the calibration position is a calibration notch provided on the outer edge of the baffle, and the chuck is provided with a positioning protrusion adapted to the calibration notch at the connection between the chuck and the chuck.

[0016] In the above solution, the calibration notch and the positioning protrusion cooperate to realize the limited installation of the wire reel on the cartridge, which is convenient for threading the consumables.

[0017] In one embodiment, a push drive assembly is provided on the first mounting seat, and the push drive assembly includes a push drive for driving the push rod to move;

[0018] The first mounting seat is slidably engaged with the linear guide rail, and the slide seat is provided with a sliding driver for connecting and driving the first mounting seat to slide on the linear guide rail. The pre-pressed plug body assembly includes a rotating kit rotatably arranged on the first mounting seat, and a pressure plate is provided on the side of the rotating kit close to the chuck, and the pressure plate is opposite to the chuck. A central through hole is provided in the center of the pressure plate for the docking plug body to pass through.

[0019] In the above scheme, the push rod is connected to the output end of the push drive through the mounting connection block, and the docking plug body can rotate relative to the push rod; on the other hand, the sliding drive is located in the lower area of ​​the linear guide rail; the rotating kit can be used as a sleeve and is rotatably mounted on the first mounting seat; the pressure plate can move synchronously toward the chuck along with the first mounting seat driven by the sliding drive, and the pressure plate is used in conjunction with the chuck to clamp the two baffles to clamp the wire reel. Since the pressure plate can rotate freely on the first mounting seat, the clamped wire reel can still rotate with the chuck, which is convenient for subsequent winding operations. In addition, the pressure plate and the docking plug body are independent, and the two processes of the pressure plate pressing the wire reel and the docking plug body extending into the center tube and clamping the consumables located in the center tube are independent; on the other hand, after the consumables are loaded on the reel, the driving push rod can be used to drive the docking plug body to further squeeze the part of the consumables located inside the center tube, so that the part of the consumables is cut off, so that the consumables reel after loading no longer has the defect of a "tail" remaining in the center tube. Furthermore, the outer ring of the front portion of the docking plug is provided with a tapered ring. This design makes the front portion of the docking plug narrower, facilitating docking with the center tube and providing space for the end of the consumable to be squeezed between the docking plug and the inner wall of the center tube. Furthermore, in other technical solutions, the front portion of the docking plug can be designed with a tapered shape, which also achieves the effect of narrowing the front portion of the docking plug.

[0020] In one embodiment, it includes a consumable material feeding mechanism, which includes a mounting plate and a wire clamping and conveying assembly. A slide rail is obliquely arranged on the mounting plate, and a mounting slider is slidably arranged on the slide rail. The wire outlet head and the wire clamping and conveying assembly are both installed on the mounting slider. The wire clamping and conveying assembly includes a double-rod slide cylinder, and a clamping cylinder is arranged on the double-rod slide cylinder. The clamping cylinder is provided with a tightenable clamp, and the clamp cooperates with the consumable material, and the clamp is located behind the wire outlet head.

[0021] In the above scheme, the consumable feeding mechanism can supply consumables, and the double-rod slide cylinder is the AirTac STWA32X50S double-rod slide cylinder, which can make the clamp cylinder slide in a straight line; after a reel is wound and loaded, an air shear will be used to cut the consumables to insert the wire into the reel to prevent the consumables from loosening; and after the air shear cuts the consumables, in order to allow the consumables to be transported again after the interruption so as to carry out the winding and loading operation of the next reel, a wire clamping and conveying assembly is designed, in which the clamp can clamp the consumables, and the double-rod slide cylinder is used to make the clamp cylinder perform reciprocating motion. In this way, by adjusting the clamp cylinder to adopt a clamping and loosening form in a reciprocating stroke, the purpose of clamping the consumables and pulling the consumables for transportation can be achieved, and ultimately the consumables can be continuously transported. Among them, since the material roll formed by the consumables becomes thicker and thicker when the reel is empty and fully loaded, it is necessary to design and install a slider so that the outlet head can move up and down to adapt the consumables coming out of the outlet head to be evenly distributed and neatly arranged during the reel winding and loading process.

[0022] In one embodiment, the consumable line tail threading mechanism includes a second mounting seat and an oblique driver for driving the second mounting seat to move obliquely up and down, and the second mounting seat is respectively provided with lifting cylinders for driving the gas shear, the first rotating chuck, the second rotating chuck and the wire pulling chuck cylinder to lift and lower. The gas shear is arranged on the output end of the corresponding lifting cylinder through an inclined mounting plate, and the first rotating chuck and the second rotating chuck are respectively arranged on the output end of the corresponding lifting cylinder through a rotary cylinder; the wire pulling chuck cylinder is arranged on the second mounting seat through a transverse driving cylinder.

[0023] In the above scheme, the rotary cylinder is an AirTac HRQ20 rotary cylinder, and the first and second rotary chucks are both AirTac FHZ pneumatic finger cylinders. The air shear, the first and second rotary chucks can all be raised and lowered as a whole through the oblique upward and downward movement of the second mounting seat. The consumable wire tail threading mechanism is used to cut the consumable wire body and perform the purpose of threading and fixing the consumable end after the winding is completed. Therefore, it is only used when the consumables are about to be wound and need to be cut. Therefore, the second mounting seat is designed to be liftable. At other times, the second mounting seat is raised to prevent the consumable wire tail threading mechanism from interfering with the operation of other components. On the other hand, the wire pulling chuck cylinder can achieve a lateral movement, that is, a pulling effect, by driving the cylinder laterally.

[0024] In one embodiment, it includes a wire reel feeding mechanism, the wire reel feeding mechanism includes a wire reel feeding station, a reel taking assembly arranged above the wire reel feeding station, a lifting assembly arranged below the wire reel feeding station and a rotating hopper arranged between the wire reel feeding station and the lifting assembly, the rotating hopper includes a mounting plate, a plurality of wire reel positioning rods arranged in a circumferential array on the mounting plate and a rotating drive for driving the mounting plate to rotate, the mounting plate is provided with a notch on the side of the wire reel positioning rod, the lifting assembly includes a lifting block and a lifting drive for driving the lifting block to rise and fall, the lifting block is adapted to the notch, the reel taking assembly includes a reel taking clamp for transferring the wire reel to the wire reel angle adjustment mechanism at the wire reel feeding station;

[0025] The disc taking assembly includes a horizontally arranged linear module and a disc taking lifting cylinder installed on the slide of the linear module, and the disc taking claw is installed on the output end of the disc taking lifting cylinder;

[0026] The lifting drive includes a vertically arranged screw transmission module, and the lifting block is installed on the screw nut of the screw transmission module;

[0027] The wire drum feeding mechanism includes an empty load detection sensor;

[0028] A wire drum labeling assembly is provided between the wire drum rotation winding mechanism and the wire drum angle adjustment mechanism. The wire drum labeling assembly includes a labeling machine. The labeling machine is a tape labeling machine. A labeling area is provided on the outer side of the baffle of the wire drum. The labeling machine labels the labeling area.

[0029] In the above scheme, the wire reel feeding mechanism can transport empty wire reels, the wire reel positioning rod is arranged vertically and can be used to set multiple empty wire reels, and the rotating hopper can rotate to make each wire reel positioning rod come to the bottom of the wire reel feeding station in turn; when it is below the wire reel feeding station, since the rotating hopper is provided with a gap, the lifting block can be used to lift the wire reel on the wire reel positioning rod as a whole from the gap. When the lifting block lifts the wire reel on the same wire reel positioning rod upward as a whole, the wire reel on the top layer will come to the wire reel feeding station, and then it can be grasped by the reel picking claw of the reel picking assembly and transferred to the wire reel angle adjustment mechanism. The reel picking claw is a Japanese SMC air gripper MHS3 finger cylinder. Among them, the wire reel on the top layer coming to the wire reel feeding station means that the center tube of the wire reel on the top layer is in a position where at least a part or even completely extends out of the top of the corresponding wire reel positioning rod. In addition, the lifting drive includes a vertically arranged screw transmission module, and the lifting block is installed on the screw nut of the screw transmission module. The reel assembly is provided with a material reel position detection sensor at the corresponding position of the reel loading station. The material reel position detection sensor is used to detect whether there is a reel at the reel loading station, and it is linked to the reel assembly. In addition, the no-load detection sensor is located below the path through which the gap passes. When one of the reel positioning rods is at the reel loading station, the position below the gap at the adjacent reel positioning rod in the reverse direction of the rotation direction of the installation disk is the installation position of the no-load detection sensor. The no-load detection sensor is used to detect whether there is a reel on the reel positioning rod that is about to enter the reel loading station. Under normal circumstances, if no reel is detected, an alarm can be triggered to prompt the operator to refill the rotating silo.

[0030] In one embodiment, a weighing mechanism is included, wherein the weighing mechanism includes an electronic scale provided on one side of the wire reel rotating winding mechanism, the wire reel is placed flat on the electronic scale for weighing, or a material unwinding rack for vertically placing the wire reel is provided on the upper portion of the electronic scale, and the wire reel is placed vertically on the material unwinding rack for weighing; a good product conveyor belt and a bad product conveyor belt are provided behind the weighing mechanism;

[0031] An air blowing and dust removal mechanism is provided in front of the weighing mechanism, and the air blowing and dust removal mechanism includes an air blowing cylinder for blowing air to the consumables loaded on the wire reel.

[0032] In the above scheme, an air cylinder is used to blow air into the consumables to remove dust. A loading robot grabs and removes the wound and mounted reels. The reels are then blown through the air and dust removal mechanism to remove dust. The weighing mechanism then weighs the reels. Unqualified reels are transferred to the defective conveyor belt by the loading robot, while qualified reels are transferred to the qualified conveyor belt by the loading robot.

[0033] In one embodiment, the loading robot includes a hinge side posture group cylinder, a connecting plate arranged at the rotating head of the hinge side posture group cylinder, and two left and right material picking and placing claws arranged on the connecting plate.

[0034] In this solution, the hinged side-position cylinder is the HC-3240L's 90-degree tilting cylinder. This cylinder drives the connecting plate to rotate 90 degrees, enabling the loading robot to grasp a flat reel at the reel angle adjustment mechanism, then tilt it 90 degrees vertically, allowing it to be easily installed on the chuck and cartridge. Designing two pick-and-place grippers is more convenient for maneuvering and coordinating with other components than a single one.

[0035] Another aspect of the present invention is to provide a consumables loading and threading method using a consumables loading and threading mechanism, characterized in that it includes the following steps:

[0036] Step 1: Use the reel removal component to grab the empty reel and place it on the reel angle adjustment mechanism to adjust the angle until the reel angle meets the preset angle;

[0037] Step 2: Use a labeling machine to label the reel;

[0038] Step 3: The loading robot takes the wire reel and installs it on the barrel;

[0039] Step 4: The consumable material is delivered from the outlet and can be inserted into the thread end perforation of the wire reel on the barrel. The part of the consumable material inserted into the thread end perforation has a certain length, and this part of the consumable material enters the interior of the central barrel;

[0040] Step 5: Drive the pressure plate and the docking plug to move toward the wire drum, so that the pressure plate can press the wire drum tightly, and the docking plug can be inserted into the center tube and squeeze the part of the filament that extends into the center tube. In this way, the wire drum is restrained and fixed, and the filament is fixed on the wire drum;

[0041] Step 6: The rotary drive can be used to rotate the cartridge, which can also drive the reel to rotate. The slide can be used to move the cartridge laterally along its axis, which can also drive the reel to move laterally. Therefore, the reel can rotate and move laterally. In addition, the outlet head itself can be moved up and down diagonally by installing a slider. Therefore, the consumables output by the outlet head can be neatly arranged and wound on the reel until the winding is completed.

[0042] In step 7, the clamping cylinder of the wire conveying assembly clamps and fixes the consumables located behind the outlet head, the second mounting seat descends and drives the air shear, the first rotating chuck and the second rotating chuck to descend, then the first rotating chuck can clamp the consumables, and then the air shear can cut the consumables in front of the outlet head, so that the consumables wound on the wire drum form a consumable end and the consumable end is clamped by the first rotating chuck, then the first rotating chuck rotates toward the direction of the second rotating chuck, so that the end of the consumable end can face a wire tail perforation on the baffle, and then the sliding seat is used to move the wire drum to move, so that the consumable end can be inserted into the wire tail perforation on the wire drum that is coming over. After the consumable end passes through a wire tail perforation, the wire pulling chuck cylinder can be used to clamp and pull the consumable. The end portion makes the end portion of the consumable straight and makes the end portion of the consumable extend as far as possible to the outside of the baffle. Then, the second rotating chuck clamps the end portion of the consumable and rotates it so that the end portion of the consumable faces the other wire tail through-hole. At the same time, the wire pulling chuck cylinder releases the consumable. During the process, the cartridge can be driven to rotate the wire reel by an angle so that the end portion of the consumable is just facing the wire tail through-hole. Then, the sliding seat can also be used to move the wire reel so that the end portion of the consumable can be inserted into the second wire tail through-hole on the wire reel that is coming over. At this point, the end portion of the consumable has been inserted back and forth through the two wire tail through-holes and can be fixed on the wire reel, thereby simulating the action of manual threading by humans. Then, the second mounting seat rises and resets and drives the air shear, the first rotating chuck and the second rotating chuck to rise away from the consumable.

[0043] Step 8: Drive the push rod to drive the docking plug to further squeeze the portion of the consumable material inside the central tube so that the portion of the consumable material can be cut off. Steps 7 and 8 are performed in no particular order.

[0044] Step 9: The loading robot comes over to grab the wire reel that has been wound and loaded, and then performs air blowing and dust removal at the air blowing and dust removal mechanism, and then weighs it at the weighing mechanism. If the weight is unqualified, the loading robot will transfer it to the defective product conveyor belt for loading and unloading. If the weight is qualified, the loading robot will transfer it to the good product conveyor belt for loading and unloading.

[0045] The cam is adapted to hold the wire end of the wire in the drawer and to allow the wire end of the wire to be threaded onto the drawer, thereby allowing the cam to be loaded onto the drawer and the wire end of the wire to be loaded onto the drawer. The consumable coming out of the head forms a consumable end portion of the consumable wound on the wire drum and the consumable end portion is clamped by the first rotating chuck. Then, the first rotating chuck rotates toward the second rotating chuck, so that the end portion of the consumable end portion can be directed toward a wire tail perforation on the baffle. The outer diameter of the chuck is smaller than the outer diameter of the baffle, so the wire tail perforation is exposed outside the chuck. In addition, after the consumable end portion passes through the first wire tail perforation, the consumable end portion can be clamped by the second rotating chuck. Then, the second rotating chuck drives the consumable end portion to rotate, and the chuck also rotates, so that the end portion of the consumable end portion clamped and rotated by the second rotating chuck can be directed toward the second wire tail perforation on the baffle, and the consumable end portion can pass through the second wire tail perforation. The consumable end portion can be fixed on the wire drum after passing through the two wire tail perforations in the form of a back and forth interlacing. The threading step of this consumable wire tail threading mechanism is a mechanized reproduction of the manual threading step, which automatically replaces manual labor and improves efficiency. After the threading of the consumable end is completed, the consumable will be fixed on the reel and will not be loose. Then, the reel loaded with consumables is transferred by the loading robot to the weighing mechanism for weighing to screen out fully loaded reels with qualified and unqualified weights. The unqualified fully loaded reels are taken away by the loading robot and unloaded from the defective product conveyor belt, and the qualified fully loaded reels are taken away by the loading robot and transferred to the good product conveyor belt for unloading and shipment. In summary, the present invention can mechanizedly complete the winding and loading of consumables, as well as the detection and screening, packaging, output and unloading steps step by step from the empty reel, greatly improving the efficiency of consumables from reel loading to packaging and shipment.

[0046] In one embodiment, in step 4, the consumables are conveyed out from the outlet, and in step 7, after the consumables are cut by the air shear, the consumables need to continue to be conveyed out from the outlet when executing the next round of consumable loading and threading. This is achieved by the reciprocating driving of the consumables by the clamping cylinder of the wire clamping and conveying assembly. Specifically, the clamp can clamp the consumables, and the double-rod slide cylinder is used to make the clamping cylinder reciprocate. In this way, the clamping cylinder is adjusted to adopt a clamping and loosening form in a reciprocating stroke, which can achieve the purpose of clamping the consumables and pulling the consumables for conveying, and ultimately the consumables can be continuously conveyed.

[0047] In the above scheme, the wire clamping and conveying assembly performs the action of conveying the consumables only when the initial end or the end of the consumables extends toward the thread head perforation of the wire reel and extends into the thread head perforation. In the process of the wire reel following the rotation of the clamping cylinder, the consumable winding is directly driven by the rotating driver to pull the consumables out from the thread outlet. Therefore, this process does not require the wire clamping and conveying assembly to perform the conveying action. BRIEF DESCRIPTION OF THE DRAWINGS

The consumable 5 can be cut by the air shear 31 and form a consumable end 35. The first rotating chuck 32 and the second rotating chuck 33 can be clamped and rotated in steps to allow the consumable end 35 to pass through the two wire tail through-holes 44 in sequence.

[0059] In the above scheme, the chuck 11 can be used to install an unloaded wire drum 4. Since the chuck 12 is shorter than the center tube 41, when the wire drum 4 is installed on the chuck 12, a part of the inside of the center tube 41 is not covered by the chuck 12, and the wire end through-hole 43 is located on the uncovered part of the center tube 41, that is, the wire end through-hole 43 is located on the center tube 41 near the baffle 42. On the other hand, when the wire reel 4 is loaded into the cartridge 12, the wire outlet head 21 and the wire end through-hole 43 can correspond to each other, that is, after the consumable 5 is conveyed out from the wire outlet head 21, it can be inserted into the wire end through-hole 43; the wire end of the consumable 5, that is, the initial end, can be fixed by the pre-pressed plug assembly 22 after being inserted into the wire end through-hole 43, specifically: the pushing rod 222 can insert the docking plug body 223 into the inner cavity of the center tube 41, and the docking plug body 223 can rotate relative to the pushing rod 222, wherein the rotating connecting member 224 is a ball bearing connection structure; the part of the consumable inserted into the wire end through-hole 43 will enter the interior of the center tube 41, and can be squeezed and stuck by the docking plug body 223 after being inserted into the center tube 41. When the end of the consumable 5 is stuck, it is clamped between the docking plug body 223 and the inner wall of the center tube 41, so that the starting end of the consumable 5 can be fixed on the wire reel 4.On the other hand, the chuck 11 and the cartridge 12 can be driven to rotate by the rotary driver 13, and the chuck 11 and the cartridge 12 can be moved linearly synchronously with the slide 15 driven by the slide driver 16, so the cartridge 12 can drive the wire drum 4 to rotate and move laterally, so together with the outlet head 21 that can convey the consumables 5, the consumables 5 can be neatly wound and loaded onto the wire drum 4; on the other hand, after the winding and loading is completed, the consumables 5 need to be cut off, so the present invention is equipped with a consumable wire tail threading mechanism 3, and the air shear 31 cuts the consumable 5 wire body and the consumable end 35 connected to the wire drum 4 is threaded The consumable end 35 is fixed to the reel 4 in the form of preventing the consumables 5 on the reel 4 from becoming loose; the consumable end 35 is fixed to the reel in the form of threading back and forth, specifically, the first rotating chuck 32 can clamp the consumable 5, and then the air shear 31 can cut the consumable 5 coming out of the outlet head 21, so that the consumable 5 wound on the reel 4 forms a consumable end 35 and the consumable end 35 is clamped by the first rotating chuck 32, then, the first rotating chuck 32 rotates toward the direction of the second rotating chuck 33, so that the end of the consumable end 35 can be toward a wire tail through-hole 44 on the baffle 42, wherein the chuck 11 The outer diameter is smaller than that of the baffle 42, so the wire end through-hole 44 is exposed outside the chuck 11. In addition, the sliding seat 15 can be used to move the wire drum 4 to move, so that the consumable end 35 can be inserted into the wire end through-hole 44 on the wire drum 4 that is coming over. At this time, the consumable end 35 passes through between the two baffles 42 to the outside of one baffle 42. At this time, the wire pulling chuck cylinder 34 can clamp and pull the consumable end 35 to make the consumable end 35 straight, and make the consumable end 35 extend as much as possible to the outside of the baffle 42. Then, the second rotating chuck 33 can clamp and rotate the consumable end 35 Then the consumable end 35 is directed toward the other end-of-line perforation 44, and at the same time the wire pulling chuck cylinder 34 releases the consumable 5. During the process, the cartridge 12 can be driven to rotate the wire drum 4 by an angle, so that the consumable end 35 is exactly opposite the end-of-line perforation 44. Then, the sliding seat 15 can also be used to move the wire drum 4, so that the consumable end 35 can be inserted into the second end-of-line perforation 44 on the wire drum 4 that is coming over. At this point, the consumable end 35 has been inserted back and forth through the two end-of-line perforations 44 and can be fixed on the wire drum 4, thereby simulating the action of manually threading the consumable 5 to fix it on the wire drum 4. After cooperating with the first rotating chuck 32 and the second rotating chuck 33 to move back and forth, the sliding seat 15 returns to the initial origin, which is a clever design. The threading step of the consumable end-of-line threading mechanism 3 is a mechanized reproduction of the manual threading step, which automatically replaces manual labor and improves efficiency. After the consumable end 35 is threaded, the consumable 5 will be fixed on the reel 4 without loosening, and the fixation of the thread head and tail can be mechanized during the winding and loading process, thereby greatly improving the efficiency of the reel winding and loading.

[0060] In one embodiment, it includes a wire reel angle adjustment mechanism 6 and a loading robot 7 for taking and placing the wire reel 4;

[0061] The reel angle adjustment mechanism 6 includes a limited rotating clamp 61, an optical fiber sensor 62, and an optical fiber sensor mounting seat 63 for mounting the optical fiber sensor 62. The optical fiber sensor mounting seat 63 is provided with a positioning slide 64 driven by a screw rod. The optical fiber sensor 62 is mounted on the positioning slide 64. The outer side surface of the baffle 42 of the reel 4 is provided with a calibration position 65. The optical fiber sensor 62 cooperates with the calibration position 65.

[0062] The loading robot 7 includes a material taking and placing clamping claw 71, and the material taking and placing clamping claw 71 is adapted to the central tube 41 of the wire drum 4;

[0063] The unloaded wire drum 4 is adjusted in placement angle by the wire drum angle adjustment mechanism 6 , and then transferred by the loading robot 7 and mounted on the cartridge 12 .

[0064] In the above scheme, the reel angle adjustment mechanism 6 can place the reel 4 at a preset placement angle; the unloaded reel 4 can be transferred to the reel rotation winding mechanism 1 by the loading robot 7 and installed on the chuck 11. Since the placement angle of the reel 4 is preset, when the reel 4 is loaded into the cartridge 12, the outlet head 21 and the end hole 43 can correspond to each other, that is, after the consumables 5 are conveyed from the outlet head 21, they can be directly inserted into the end hole 43. On the other hand, the position-limiting rotary clamp 61 is a combination of a Japanese SMC air gripper MHS3 finger cylinder and a rotary cylinder. The position-limiting rotary clamp 61 is used to clamp and fix the center tube 41 of the reel 4 from bottom to top; the optical fiber sensor 62 includes a PRS-410 optical fiber amplifier line probe. When the reel angle adjustment mechanism 6 is in use, the limited rotating clamp 61 can drive the clamped reel 4 to rotate. During the rotation of the reel 4, the calibration position 65 of the reel 4 matches the optical fiber sensor 62, and the limited rotating clamp 61 stops, so that the reel 4 is placed at a preset angle, which is convenient for subsequent reel winding. Among them, the calibration notch distance from the limited rotating clamp 61 is different for reels 4 of different sizes. Therefore, in order to adapt to different reels 4, the position of the optical fiber sensor 62 is made adjustable by designing a positioning slide 64. On the other hand, the material taking and discharging clamp 71 is a Japanese SMC air gripper MHS3 finger cylinder.

[0065] In one embodiment, the calibration position 65 is a calibration notch provided on the outer edge of the baffle 42 , and the cartridge 12 is provided with a positioning protrusion 17 adapted to the calibration notch at the connection with the chuck 11 .

[0066] In the above solution, the calibration notch and the positioning protrusion 17 cooperate to achieve the limited installation of the wire reel 4 on the cartridge 12, making it convenient to thread the consumables 5.

[0067] In one embodiment, a push drive assembly 23 is provided on the first mounting seat 221, and the push drive assembly 23 includes a push driver 24 for driving the push rod 222 to move;

[0068] The first mounting seat 221 is in sliding cooperation with the linear guide rail 14, and the slide seat 15 is provided with a sliding driver 25 for connecting and driving the first mounting seat 221 to slide on the linear guide rail 14. The pre-pressed plug body assembly 22 includes a rotating kit 225 rotatably set on the first mounting seat 221, and a pressure plate 226 is provided on the side of the rotating kit 225 close to the chuck 12. The pressure plate 226 is opposite to the chuck 11, and a central through hole is provided in the center of the pressure plate 226 for the docking plug body 223 to pass through.

[0069] In the above scheme, the push rod 222 is connected to the output end of the push driver 24 through the installation connecting block, and the docking plug body 223 can rotate relative to the push rod 222; on the other hand, the sliding driver 25 is located in the lower area of ​​the linear guide rail 14; the rotating kit 225 can be used as a sleeve and rotatably installed on the first mounting seat 221; the pressure plate 226 can move toward the direction of the chuck 11 synchronously with the first mounting seat 221 driven by the sliding driver 25, and the pressure plate 226 is used to cooperate with the chuck 11 to clamp the two baffles 42 to clamp the wire drum 4. Since the pressure plate 226 can rotate freely on the first mounting seat 221, the clamped wire drum 4 can still rotate with the chuck 11, which is convenient for subsequent winding operations. In addition, the pressure plate 226 and the docking plug body 223 are independent, and the two processes of the pressure plate 226 pressing the wire drum 4 and the docking plug body 223 extending into the center tube 41 and clamping the consumables located in the center tube 41 are independent; on the other hand, after the consumables 5 are loaded onto the disk, the driving push rod 222 can be used to drive the docking plug body 223 to further squeeze the part of the consumables 5 located inside the center tube 41, so that this part of the consumables 5 can be cut off, so that the loaded consumable wire drum no longer has the defect of a "tail" remaining in the center tube 41. On the other hand, the outer ring of the front part of the docking plug body 223 is provided with a shrinking ring 227. The design of the shrinking ring 227 makes the front part of the docking plug body 223 thinner, so that it can be conveniently connected to the interior of the center tube 41, and can provide space for the end of the consumables 5 to be squeezed between the docking plug body 223 and the inner wall of the center tube 41. In addition, in other technical solutions, the front portion of the docking plug body 223 can be designed to be conical, which can also have the effect of making the front portion of the docking plug body 223 thinner and narrower.

[0070] In one embodiment, it includes a consumable material feeding mechanism 8, which includes a mounting plate 81 and a wire clamping and conveying assembly 82. A slide rail 83 is obliquely provided on the mounting plate 81, and a mounting slider 84 is slidably provided on the slide rail 83. The wire outlet head 21 and the wire clamping and conveying assembly 82 are both installed on the mounting slider 84. The wire clamping and conveying assembly 82 includes a double-rod slide cylinder 85, and a clamping cylinder 86 is provided on the double-rod slide cylinder 85. The clamping cylinder 86 is provided with a retractable clamp 87, and the clamp 87 cooperates with the consumable material 5. The clamp 87 is located behind the wire outlet head 21.

[0071] In the above scheme, the consumable feeding mechanism 8 can supply consumables 5, and the double-rod slide cylinder 85 is the AirTac STWA32X50S double-rod slide cylinder. The double-rod slide cylinder 85 can make the clamp cylinder 86 slide in a straight line; after a wire reel 4 is wound and loaded, the air shear 31 will be used to cut the consumables to insert the wire reel 4 to prevent the consumables 5 from loosening; and after the air shear cuts the consumables, in order to allow the consumables 5 to continue to be transported after the interruption and thus carry out the winding and loading operation of the next wire reel 4, a wire clamping and conveying assembly 82 is designed, and the clamp 87 can clamp the consumables 5, and the double-rod slide cylinder 85 is used to make the clamp cylinder 86 perform reciprocating motion. In this way, by adjusting the clamp cylinder 86 to adopt a clamping and loosening form in a reciprocating stroke, the purpose of clamping the consumables and pulling the consumables for transportation can be achieved, and finally the consumables 5 can be continuously transported. Among them, since the material roll formed by the consumable material 5 becomes thicker and thicker when the reel 4 is empty and fully loaded when the consumable material 5 is wound and loaded, it is necessary to design and install a slider 84 so that the outlet head 21 can move up and down to adapt the consumable material coming out of the outlet head 21 to be evenly distributed and neatly arranged during the winding and loading process of the reel 4.

[0072] In one embodiment, the consumable line tail threading mechanism 3 includes a second mounting seat 36 and an oblique driver 37 for driving the second mounting seat 36 to move obliquely up and down, and the second mounting seat 36 is respectively provided with a lifting cylinder 38 for driving the gas shear 31, the first rotating chuck 32, the second rotating chuck 33 and the wire pulling chuck cylinder 34 to move up and down. The gas shear 31 is arranged on the output end of the corresponding lifting cylinder 38 through an inclined mounting piece 39, and the first rotating chuck 32 and the second rotating chuck 33 are respectively arranged on the output end of the corresponding lifting cylinder through a rotary cylinder 310; the wire pulling chuck cylinder 34 is arranged on the second mounting seat 36 through a transverse driving cylinder 311.

[0073] In the above scheme, the rotary cylinder 310 is an AirTac HRQ20 rotary cylinder, and the first rotating chuck 32 and the second rotating chuck 33 are both AirTac FHZ pneumatic finger cylinders. The air shear 31, the first rotating chuck 32, and the second rotating chuck 33 can all be raised and lowered as a whole through the oblique upward and downward movement of the second mounting seat 36. The consumable wire threading mechanism 3 is used to cut the consumable wire 5 after winding is completed and to thread and fix the consumable end 35. Therefore, it is only used when the consumable 5 is about to be wound and needs to be cut. Therefore, the second mounting seat 36 is designed to be liftable. At other times, the second mounting seat 36 is raised to prevent the consumable wire threading mechanism 3 from interfering with the operation of other components. On the other hand, the wire pulling chuck cylinder 34 can achieve a lateral movement, that is, a pulling effect, by driving the cylinder 311 laterally.

[0074] In one embodiment, the wire drum loading mechanism 9 includes a wire drum loading station 91, a disk-taking assembly 92 arranged above the wire drum loading station 91, a lifting assembly 93 arranged below the wire drum loading station 91, and a rotating silo 94 arranged between the wire drum loading station 91 and the lifting assembly 93. The rotating silo 94 includes a mounting plate 941, a plurality of wire drum positioning rods 942 arranged in a circumferential array on the mounting plate 941, and a plurality of wire drum positioning rods 942 arranged in a circumferential array on the mounting plate 941. A rotary driver 943 is provided for driving the mounting plate 941 to rotate. The mounting plate 941 is provided with a notch 944 on the side of the wire reel positioning rod 942. The lifting assembly 93 includes a lifting block 931 and a lifting driver 932 for driving the lifting block 931 to move up and down. The lifting block 931 is adapted to the notch 944. The reel removal assembly 92 includes a reel removal clamp 933 for transferring the wire reel 4 to the wire reel angle adjustment mechanism 6 at the wire reel loading station 91.

[0075] The disc removal assembly 92 includes a horizontally arranged linear module 921 and a disc removal lifting cylinder 922 mounted on a slide of the linear module 921. The disc removal clamp 933 is mounted on the output end of the disc removal lifting cylinder 922.

[0076] The lifting drive 932 includes a vertically arranged screw transmission module 934, and the lifting block 931 is installed on the screw nut of the screw transmission module 934;

[0077] The wire drum feeding mechanism 9 includes an empty load detection sensor 95;

[0078] A wire drum labeling assembly is provided between the wire drum rotating winding mechanism 1 and the wire drum angle adjustment mechanism 6. The wire drum labeling assembly includes a labeling machine, which is a tape labeling machine. A labeling area 45 is provided on the outer surface of the baffle 42 of the wire drum 4, and the labeling machine labels the labeling area 45.

[0079] In the above scheme, the wire reel loading mechanism 9 can transport empty wire reels 4. The wire reel positioning rods 942 are arranged vertically and can be used to set multiple empty wire reels 4. The rotating hopper 94 rotates to allow each wire reel positioning rod 942 to sequentially move below the wire reel loading station 91. When below the wire reel loading station 91, because the rotating hopper 94 is provided with a notch 944, the lifting block 931 can be used to lift the wire reel 4 on the wire reel positioning rod 942 as a whole through the notch 944. When the lifting block 931 lifts the wire reel 4 on the same wire reel positioning rod 942 upward as a whole, the wire reel 4 on the top layer will move to the wire reel loading station 91. It can then be grasped by the reel retrieval claw 933 of the reel retrieval assembly 92 and transferred to the reel angle adjustment mechanism 6. The reel retrieval claw 933 is a Japanese SMC air gripper MHS3 finger cylinder. The arrival of the wire reel 4 at the top layer at the wire reel loading station 91 means that the central tube 41 of the wire reel 4 at the top layer is at least partially or completely extended beyond the top of the corresponding wire reel positioning rod 942. In addition, the lifting drive 932 includes a vertically arranged screw transmission module 934, and the lifting block 931 is installed on the screw nut of the screw transmission module 934. The reel removal assembly 92 is provided with a material reel position detection sensor at the corresponding position of the reel loading station 91. The material reel position detection sensor is used to detect whether there is a wire reel 4 at the reel loading station 91, and it is linked to the reel removal assembly 92. In addition, the empty-load detection sensor 95 is located below the path through which the gap 944 passes. When one of the wire reel positioning rods 942 is at the wire reel loading station 91, the installation position of the empty-load detection sensor 95 is below the position of the gap 944 at the adjacent wire reel positioning rod 942 in the reverse direction of the rotation direction of the mounting plate 941. The empty-load detection sensor 95 is used to detect whether there is a wire reel 4 on the wire reel positioning rod 942 that is about to enter the wire reel loading station 91. Generally, if no wire reel 4 is detected, an alarm can be triggered to prompt the operator to refill the rotating hopper 94.

[0080] In one embodiment, it includes a weighing mechanism 55, which includes an electronic scale arranged on one side of the wire reel rotating winding mechanism 1, and the wire reel 4 is placed flat on the electronic scale for weighing, or a discharge rack for vertically placing the wire reel 4 is provided on the upper part of the electronic scale and the wire reel is placed vertically on the discharge rack for weighing; a good product conveyor belt 56 and a bad product conveyor belt 57 are provided behind the weighing mechanism 55.

[0081] An air blowing and dust removal mechanism is provided in front of the weighing mechanism 55 , and the air blowing and dust removal mechanism includes an air cylinder for blowing air to the consumables 5 loaded on the wire reel 4 .

[0082] In the above scheme, the air cylinder is used to blow air into the consumables 5 to remove dust. The loading robot 7 grabs and removes the wound and mounted wire reels 4, then blows air and removes dust at the air blowing and dust removal mechanism, and then weighs it at the weighing mechanism 55. If the weight is unqualified, the loading robot 7 transfers it to the defective product conveyor belt 57 for loading and unloading. If the weight is qualified, the loading robot 7 transfers it to the qualified product conveyor belt 56 for loading and unloading.

[0083] In one embodiment, the loading robot 7 includes a hinge side posture group cylinder 72, a connecting plate 73 arranged at the rotating head of the hinge side posture group cylinder 72, and the left and right material picking and placing claws 71 arranged on the connecting plate 73.

[0084] In the above solution, the hinged side posture group cylinder 72 is a 90-degree tilting cylinder of HC-3240L. The hinged side posture group cylinder 72 can drive the connecting plate 73 to rotate 90 degrees, so that the loading robot 7 can grasp the flat wire reel 4 from the wire reel angle adjustment mechanism 6, and then turn the wire reel 4 to a 90-degree vertical position. Then, the upright wire reel 4 can be easily installed on the chuck 11 and the barrel 12. Designing two material picking and placing clamping jaws 71 is more convenient for mobilization and coordination with other components than one.

[0085] In one embodiment, the rotation drive 13, the oblique drive 37, the rotary drive 943 and the slide drive 16 are all motors, and the pushing drive 24 and the sliding drive 25 are all cylinders.

[0086] Another aspect of the present invention is to provide a consumables loading and threading method using a consumables loading and threading mechanism, characterized in that it includes the following steps:

[0087] Step 1: Use the reel assembly 92 to grab the empty wire reel 4 and place it on the wire reel angle adjustment mechanism 6 to adjust the placement angle until the placement angle of the wire reel 4 meets the preset angle;

[0088] Step 2: label the reel 4 using a labeling machine;

[0089] Step 3: The loading robot 7 takes the wire reel 4 and installs the wire reel 4 on the cartridge 12;

[0090] In step 4, the consumable material 5 is delivered from the outlet 21 and inserted into the thread end through-hole 43 of the reel 4 on the cartridge 12. The portion of the consumable material 5 inserted into the thread end through-hole 43 has a certain length, and this portion of the consumable material enters the interior of the central cartridge 41.

[0091] Step 5: Drive the pressure plate 226 and the docking plug 223 toward the wire drum 4, so that the pressure plate 226 can press the wire drum 4, and the docking plug 223 can be inserted into the center tube 41 and squeeze the part of the consumable 5 that extends into the center tube 41, thereby restraining and fixing the wire drum 4 and the consumable 5.

[0092] In step 6, the rotary driver 13 is used to rotate the cartridge 12 and drive the reel 4 to rotate. The slide 15 is used to move the cartridge 12 laterally along its axis and drive the reel 4 laterally. Therefore, the reel 4 can rotate and move laterally. In addition, the outlet head 21 itself can be moved up and down in an oblique direction by installing the slider 84. Therefore, the consumables 5 output by the outlet head 21 can be neatly arranged and wound on the reel 4 until the winding is completed.

[0093] In step 7, the clamping cylinder 86 of the wire clamping conveying assembly 82 clamps and fixes the consumables located behind the wire outlet head 21, and the second mounting seat 36 descends and drives the gas shear 31, the first rotating chuck 32 and the second rotating chuck 33 to descend. Then, the first rotating chuck 32 can clamp the consumables 5, and then the gas shear 31 can cut the consumables 5 in front of the wire outlet head 21, so that the consumables 5 wound on the wire drum 4 form a consumable end 35 and the consumable end 35 is clamped by the first rotating chuck 32. Then, the first rotating chuck 32 rotates toward the direction of the second rotating chuck 33, so that the end of the consumable end 35 can face a wire tail through-hole 44 on the baffle 42, and then the sliding seat 15 is used to move to drive the wire drum 4 to move, so that the consumable end 35 can be inserted into the wire tail through-hole 44 on the wire drum 4 that is coming over. After the consumable end 35 passes through a wire tail through-hole 44, it can be clamped and pulled by the wire pulling chuck cylinder 34. The second mounting base 36 then moves upwards and resets, driving the air shear 31, the first rotating chuck 32 and the second rotating chuck 33 to move away from the consumable 5.

[0094] Step 8: Drive the push rod 222 to drive the docking plug 223 to further squeeze the portion of the consumable material 5 located inside the central tube 41, so that the portion of the consumable material 5 can be cut off. Steps 7 and 8 are not performed in any particular order.

[0095] Step 9, the loading robot 7 comes over to grab and take away the wire reel 4 that has been wound and loaded, and then blows and removes dust at the air blowing and dust removal mechanism, and then weighs it at the weighing mechanism 55. If the weight is unqualified, the loading robot 7 transfers it to the defective product conveyor belt 57 for loading and unloading. If the weight is qualified, the loading robot 7 transfers it to the good product conveyor belt 56 for loading and unloading.

[0096] In the above scheme, the wire drum feeding mechanism 9 can convey the empty wire drum 4, wherein the wire drum angle adjustment mechanism 6 can place the wire drum 4 according to the preset placement angle; the consumable material feeding mechanism 8 can convey the consumable material 5, and the empty wire drum 4 can be transferred to the wire drum rotating winding mechanism 1 by the feeding robot 7 and installed on the chuck 11. Since the placement angle of the wire drum 4 is preset, when the wire drum 4 is loaded into the cartridge 12, the wire outlet 21 and the wire head perforation 43 can be corresponding, that is, after the consumable material 5 is conveyed out from the wire outlet 21, it can be inserted into the wire head perforation 43, so that The thread end of the consumable material 5 is fixed, and then the rotary driver 13 drives the chuck 11 and the cartridge 12 to rotate, which can cooperate with the consumable material feeding mechanism 8 to realize the operation of winding the consumable material 5 and loading it onto the reel 4; the consumable material threading mechanism 3 is used to cut the consumable material 5 wire body after the winding is completed and fix the consumable end 35 connected to the reel 4 on the reel 4 in the form of threading, so as to prevent the consumable material 5 on the reel 4 from being loose; after the winding and loading of the reel 4 is completed, the first rotating chuck 32 can clamp the consumable material 5, and then the air shear 31 can cut the consumable material coming out of the outlet head 21 The consumable material 5 is wound on the reel 4 to form a consumable material end 35 and the consumable material end 35 is clamped by the first rotating chuck 32. Then, the first rotating chuck 32 rotates toward the second rotating chuck 33, so that the end of the consumable material end 35 can be directed toward a wire tail through-hole 44 on the baffle 42. The outer diameter of the chuck 11 is smaller than the outer diameter of the baffle 42, so the wire tail through-hole 44 is exposed outside the chuck 11. In addition, after the consumable material end 35 passes through the first wire tail through-hole 44, the consumable material end 35 can be clamped by the second rotating chuck 33. After clamping, the second rotating chuck 33 drives the consumable end 35 to rotate, and the chuck 11 also rotates, so that the end of the consumable end 35 clamped and rotated by the second rotating chuck 33 can face the second wire tail perforation 44 on the baffle 42, and the consumable end 35 can pass through the second wire tail perforation 44. The consumable end 35 can be fixed on the wire drum 4 after passing through the two wire tail perforations 44 in the form of a back and forth insertion. The threading step of the consumable wire tail threading mechanism 3 this time is a mechanized reproduction of the manual threading step, which automatically replaces manual labor and improves efficiency. After the consumable end 35 is threaded, the consumable 5 will be fixed on the reel 4 without loosening. Then, the reel 4 loaded with the consumable 5 is transferred by the feeding robot 7 to the weighing mechanism 55 for weighing to screen the fully loaded reels 4 with qualified and unqualified weights. The unqualified fully loaded reels 4 are taken away by the feeding robot 7 and unloaded from the defective product conveyor belt 57. The qualified fully loaded reels 4 are taken away by the feeding robot 7 and transferred to the good product conveyor belt 56 for unloading and shipment. In summary, the present invention can mechanizedly complete the winding and loading of consumables, as well as the detection and screening, packaging, and output and unloading steps step by step from the empty reel 4, greatly improving the efficiency of consumables from reel loading to packaging and shipment.

[0097] In one embodiment, in step 4, the consumable 5 is conveyed out from the outlet head 21, and in step 7, after the consumable 5 is cut by the air shear 31, the consumable 5 needs to continue to be conveyed out from the outlet head 21 when executing the next round of consumable loading and threading. This is achieved by the reciprocating drive of the consumable 5 by the clamping cylinder 86 of the clamping and conveying assembly 82. Specifically, the clamp 87 can clamp the consumable 5, and the double-rod slide cylinder 85 is used to make the clamping cylinder 86 reciprocate. In this way, by adjusting the clamping cylinder 86 to adopt a clamping and loosening form in a reciprocating stroke, the purpose of clamping the consumable and pulling the consumable for conveying can be achieved, and finally the consumable 5 can be continuously conveyed.

[0098] In the above scheme, the wire clamping and conveying assembly 82 performs the action of conveying the consumable 5 only when the initial end or the end portion 35 of the consumable 5 extends toward the thread end perforation 43 of the wire reel 4 and extends into the thread end perforation 43. In the process that the wire reel 4 rotates following the chuck 12, the winding of the consumable 5 is directly driven by the rotating driver 13 to pull the consumable 5 out from the thread outlet 21. Therefore, this process does not require the wire clamping and conveying assembly 82 to perform the conveying action.
