Description

Technical Field

[0001] The invention relates to the field of plate and strip grinding, and in particular to a grinding brush disc forming device. Background Art

[0002] The plate and strip are usually made by hot rolling process. Before actual use, rust, oxide scale, etc. will appear on the surface of the plate and strip, and the surface of the plate and strip needs to be brushed by a brush roller. To facilitate disassembly and maintenance, an existing brush roller structure is configured to sleeve multiple grinding brush discs on the roller shaft, and the grinding brush disc includes a brush disc, and the inner side of the brush disc is provided with multiple wire holes evenly distributed along the circumferential direction. Wires made of resin material are passed through the wire holes to form two strands of wire located at both ends of the brush disc. The two strands of wire are folded in half along the radial direction away from the brush disc to form a wire bundle. The wire bundle fixes the two strands of wire by hot melt welding to facilitate grinding the surface of the plate and strip.

[0003] When this type of grinding brush disc is being formed, workers at different workstations need to manually perform multiple forming processes in sequence. The workers need to thread wires of predetermined lengths through the multiple wire holes of the brush disc one by one to form two strands of wire, and then fold the two strands of wire at each wire hole outward one by one to form multiple wire bundles exposed outside the brush disc, thus completing the wire planting process of the brush disc. After the wire planting is completed, the two strands of wire folded outward are elastic and therefore easily spread outward. At this time, the two strands of wire need to be pressed tightly against the end face of the brush disc, and then a hot melt welding machine is used to fix the multiple wire bundles one by one. This manual operation has low processing efficiency, and when grinding brush discs are mass-produced, the labor and time costs of production are high. Summary of the invention

[0004] The present invention provides a grinding brush disc forming device, which arranges a rotating mechanism for transferring brush discs between a wire planting mechanism and a hot-melt welding mechanism, and loads a plurality of brush discs that are not seeded with wires onto a wire pressing assembly of the rotating mechanism one by one, so that the brush discs that are not threaded with wires are sequentially subjected to wire planting processing and wire bundle welding processing by the rotating mechanism to become grinding brush discs with a grinding function, thereby improving the degree of automation in the processing of the grinding brush discs, reducing the time and cost of manual processing of the grinding brush discs, and improving the forming efficiency of the grinding brush discs.

[0019] Preferably, a plurality of radial guide grooves connected by radial slide grooves are evenly distributed along the circumferential direction on the end surface of the upper pressure plate facing away from the brush plate and the end surface of the lower pressure plate facing away from the brush plate, and the radial pressure rod is provided with a protrusion that exceeds the end surface of the upper pressure plate facing away from the brush plate or the end surface of the lower pressure plate facing away from the brush plate and is slidably connected to the radial guide groove; the upper push-pull assembly comprises an upper push-pull rod and an upper push-pull cylinder, the upper push-pull rod is located on the inner side of the protrusion of the upper pressure plate, and the lower push-pull assembly comprises a lower push-pull rod and a lower push-pull cylinder, and the lower push-pull rod is located on the inner side of the protrusion of the lower pressure plate; when the wire folding frame stacks the two strands of wire outward into a wire bundle, the upper push-pull cylinder and the lower push-pull cylinder respectively drive the upper push-pull rod and the lower push-pull rod to move in the direction away from the brush plate and act on the corresponding protrusions, so that the corresponding radial pressure rod extends out and presses the two strands of wire against the corresponding end surface of the brush plate; after the two strands of wire are stacked into a wire bundle, they remain fixed and do not spread outward, which is convenient for the next step of hot melt welding.

[0020] Preferably, a wire-drawing mechanism is provided on the wire-seeding mechanism, which includes a movable lever and a rotating shaft extending in the longitudinal direction, a wire-drawing driving member is connected to the rotating shaft, and the rotating shaft is connected to the movable lever by a linkage rod; when two strands of wire in one of the wire holes on the brush disc are superimposed into a wire bundle, the upper pressure plate and the lower pressure plate rotate and align the next wire hole of the brush disc with the prepared wire for re-threading, the wire-drawing driving member drives the rotating shaft to rotate, and links the movable lever to move between the adjacent wire holes that have been threaded and the wire holes that have not been threaded on the brush disc, so as to draw the wire bundle at the position of the threaded wire holes along the circumferential direction of the brush disc; so that the wire bundle at the threaded wire hole will not fork to the side of the wire hole that has not been threaded, to ensure that the wire bundle on the side of the threaded wire hole will not be drawn into the next wire bundle to be formed.

[0021] The beneficial effects of the present invention using the above technical solution are: The grinding brush disc forming device of the present invention automates and integrates the processing process of the grinding brush disc. A rotating mechanism for transferring the brush disc is arranged between the wire planting mechanism and the hot-melt welding mechanism, and multiple brush discs that have not been seeded with wire are fed one by one onto the wire pressing assembly of the rotating mechanism. The brush discs that have not been threaded with wire are sequentially processed by the rotating mechanism for wire planting and wire bundle welding to become grinding brush discs with grinding function. This reduces the time and cost of manual processing of the grinding brush discs and improves the forming efficiency of the grinding brush discs.

[0022] The grinding brush disc forming device of the present invention is provided with a grabbing mechanism, which can grab the brush disc that has not been threaded with wire for loading, grab the formed grinding brush disc for unloading, and also grab the upper pressing plate on the turntable to convert between the installation position and the semi-installation position on the turntable, and realize the cyclic loading of the brush disc and the cyclic unloading of the grinding brush disc. This design makes the wire pressing assembly on the turntable recyclable, saves the time of transporting materials at each workstation, and maximizes the processing efficiency of the grinding brush disc.

[0023] When threading the wire in the wire-seeding mechanism, the method of threading the wire first, then pulling and then cutting is adopted to pull the prepared wire into place in the wire hole of the brush disc at one time, and the wire cutting mechanism is used to form a predetermined length of cut wire in the wire hole. The whole wire-threading process is smooth and efficient, which improves the efficiency of threading the wire in the wire hole.

[0024] After the wire threading is completed, the stranded wires on both sides of the brush disc are folded outward into a wire bundle through the wire folding mechanism, and the upper push-pull assembly and the lower push-pull assembly act on the protrusions and drive the radial pressure rods to extend outward, thereby pressing the stranded wires against the end face of the brush disc, so that the stranded wires on the brush disc will not spread outward due to their own elasticity, ensuring that the next wire bundle welding process proceeds smoothly.

[0025] After the corresponding wire holes on the brush disc are seeded with wire, a wire bundle will be formed at the wire hole that has been threaded with wire. The wire bundle itself is elastic, so it is easy to fork to the side of the wire hole that has not been threaded with wire. The forked wire material is easy to be rolled into the next wire bundle to be formed by the wire folding frame when it is folded in the next wire hole. Therefore, the wire drawing mechanism in the present invention can drive the movable lever to move between the wire hole that has been threaded with wire and the wire hole that has not been threaded with wire through the wire drawing drive part, and pull the wire bundle on the side of the wire hole that has been threaded with wire together, ensuring that the next wire hole can be threaded and folded normally, thereby ensuring the seeding quality of the brush disc.

[0031] Further, if Figure 20-21As shown, in order to improve the feeding efficiency of the brush disc 9, three installation positions are provided on the turntable 62, and the installation positions are divided into full installation positions corresponding to the first processing station and the second processing station, and semi-installation positions corresponding to the material station. The full installation position is provided with an upper pressure plate 631 and a lower pressure plate 638 that are matched up and down; the semi-installation position is provided with a lower pressure plate 638; the grasping mechanism 5 first switches to the material grasping mode, and after grasping the brush disc 9 and feeding it to the lower pressure plate 638, the grasping mechanism 5 switches to the disc grasping mode, and grasps the upper pressure plate 631 of the previous full installation position to match it to the upper end of the lower pressure plate 638 of the semi-installation position, and converts the previous full installation position into a semi-installation position with only the lower pressure plate 638; then the turntable 62 rotates and makes the lower pressure plate 638 on the previous semi-installation position align with the material station; the cycle is repeated, so that multiple brush discs 9 are loaded one by one to each installation position on the turntable 62; the process of manually placing the brush disc 9 is eliminated, thereby improving the feeding efficiency.

[0032] Further, if Figure 22-23 As shown, the gripping mechanism 5 cooperates with the rotating mechanism 6 to improve the unloading efficiency of the brush disc. After the brush discs 9 are loaded on all the mounting positions on the turntable 62, the previous mounting position adjacent to the material station only has the lower pressure plate 638 and the formed brush disc loaded on the upper end of the lower pressure plate 638. Then the turntable 62 rotates and turns the formed brush disc back and aligns it with the material station, and then the formed brush disc is removed by the gripping mechanism 5. This cycle is repeated to unload all the brush discs on the turntable 62 one by one. The process of manually removing the brush disc is eliminated, thereby improving the unloading efficiency.

[0033] Furthermore, when the grabbing mechanism 5 is in the disc grabbing mode, the grabbing mechanism 5 can directly grab the upper pressure plate 631 on the installation position corresponding to the hot melt welding mechanism 4, and align the upper pressure plate 631 to the lower pressure plate 638 on the semi-installation position corresponding to the position of the material table 2. However, the grabbing mechanism 5 is easy to interfere with the hot melt welding mechanism 4 when moving. Therefore, in this embodiment, there is also a vacant waiting position between the material station and the second processing station, and the turntable 62 has a full installation position corresponding to the waiting position. When the brush disc 9 is loading or the grinding brush disc is unloading, the grabbing mechanism 5 grabs the upper pressure plate 631 from the full installation position corresponding to the waiting position and aligns it to the lower pressure plate 638 on the semi-installation position; the wire pressing assembly at the waiting position can increase the amount of brush disc 9 loading on the turntable 62, and at the same time, the grabbing mechanism 5 does not need to move to the full installation position corresponding to the hot melt welding mechanism 4, thereby avoiding interference between the grabbing mechanism 5 and the hot melt welding machine when grabbing the upper pressure plate 631.

[0034] Furthermore, although the above-mentioned cyclic loading and unloading methods can improve the processing efficiency of the brush disc 9, the gripping mechanism 5 needs to remove the formed grinding brush disc after loading multiple brush discs 9 to the corresponding installation positions. The process of removing the grinding brush disc takes some time. Therefore, in order to further improve the processing efficiency of the brush disc 9, in addition to cyclic loading and unloading, the present embodiment can also load and unload materials synchronously. That is, after all the installation positions on the turntable 62 are loaded with the brush disc 9, a formed grinding brush disc is taken out from the semi-installation position by the grabbing mechanism 5, and an unseeded brush disc 9 is placed on the same semi-installation position, and then the upper pressure plate 631 of the previous full installation position is grabbed and matched to the upper end of the lower pressure plate 638 of the semi-installation position, and the previous full installation position is converted into a semi-installation position with only the lower pressure plate 638 and the grinding brush disc loaded on the upper end of the lower pressure plate 638, and then the turntable 62 rotates to make the grinding brush disc on the previous semi-installation position rotate back to the position corresponding to the material position, and the brush disc 9 and the grinding brush disc are alternately reciprocated to realize Synchronous loading and unloading of grinding brush discs; according to different processing requirements, the operator can freely choose between the cyclic loading and unloading mode and the synchronous loading and unloading mode; when there are many unthreaded brush discs 9 on the material table 2, the operator can choose synchronous loading and unloading, so that the grabbing mechanism 5 can remove the formed grinding brush disc from the semi-installation position and load an unthreaded brush disc 9 to the semi-installation position at the same time, thereby improving the forming efficiency of the grinding brush disc; but when there are fewer unthreaded brush discs 9 on the material table 2 or the operator needs to unload all the formed grinding brush discs, the operator can choose synchronous loading and unloading to avoid leaving the formed grinding brush discs on the turntable 62.

[0035] Further, if Figure 3 As shown, the stepper drive is a first stepper motor 61 arranged at the lower end of the turntable 62. The first stepper motor 61 drives the turntable 62 to rotate step by step, so that the brush plate 9 passes through the first processing station and the second processing station in sequence from the material station to become a grinding brush plate returning to the material station.

[0036] Furthermore, in order to make the next wire hole 91 on the brush plate align with the wire seeding mechanism or the hot melt welding machine when the upper pressure plate 631 and the lower pressure plate 638 are gradually rotated, the wire pressing assembly 63 also includes a support shaft 636 that can rotate along its own axis direction, and the upper pressure plate 631 and the lower pressure plate 638 are arranged at the top of the support shaft 636 and are circumferentially fixed to the support shaft 636; a second stepper motor 64 is provided at the corresponding position of the first processing station and the second processing station on the machine platform 1, and the second stepper motor 64 is provided at the corresponding position of the first processing station and the second processing station. 4 is provided with an active seat 641, and a driven seat 637 is provided at the bottom end of the support shaft 636, and a clutch driving mechanism is formed between the active seat 641 and the driven seat 637; the clutch driving mechanism is an electromagnetic clutch, and when a wire hole 91 on the brush plate 9 completes the seed wire or wire bundle welding, the electromagnetic clutch is energized, and the second stepper motor 64 drives the active seat 641 to form a magnetic coupling force on the driven seat 637, so that the next wire hole 91 of the brush plate 9 rotates to a predetermined position and performs the seed wire or wire bundle welding.

[0037] Further, if Fig.24 As shown, the upper pressure plate 631 and the lower pressure plate 638 need to remain stable after being matched. When the grasping mechanism 5 grasps the upper pressure plate 631, the upper pressure plate 631 and the lower pressure plate 638 need to be separated from each other. Therefore, in order to meet this usage requirement, a center hole is provided on the upper pressure plate 631 and the lower pressure plate 638, and a support shaft 636 is concentrically installed at the center hole position. A control component for controlling the mutual locking and unlocking of the upper pressure plate 631 and the lower pressure plate 638 is provided at the center hole position. The control component includes a matching sleeve 66 concentrically connected to the center hole 63a position of the upper pressure plate 631, an accommodating hole is provided at the upper end portion of the support shaft 636, a through limiting hole 636a is provided on the inner wall of the accommodating hole, a movable limiting ball 68 is provided in the limiting hole 636a, and a limiting ball 68 corresponding to the position of the limiting ball 68 is provided on the matching sleeve 66 The movable shaft 67 is provided with a compression spring 661 at the lower end of the movable shaft 67, and the compression spring 661 provides elastic force for elastic expansion and contraction for the movable shaft 67; the movable shaft 67 includes a large diameter section 672 and a small diameter section 671; the large diameter section 672 of the movable shaft 67 resists and makes the limiting ball 68 stuck in the limiting groove 662, so that the upper pressure plate 631 and the lower pressure plate 638 remain locked; the grasping mechanism 5 includes a first grasping component and a retractable pressing member 52. When the grasping mechanism 5 grasps the upper pressure plate 631, the pressing member 52 acts on the movable shaft 67 to elastically expand and contract, so that the small diameter section 671 corresponds to the position of the limiting ball 68. At this time, the limiting ball 68 escapes from the limiting groove 662 and unlocks the upper pressure plate 631 and the lower pressure plate 638, so that the first grasping component can grasp the upper pressure plate 631.

[0038] Furthermore, the first grabbing assembly grabs the upper pressure plate 631 in the following manner: the mating sleeve 66 has a mating portion that extends upwardly beyond the end face of the upper pressure plate 631, and an inwardly concave annular slot 663 is provided on the outer wall of the mating portion. The first grabbing assembly includes two opposing grabbing cylinders, each of which has a telescopic rod 53. When the pressing member 52 acts on the movable shaft 67, the two telescopic rods 53 extend out and are inserted into the annular slot 663 to form a grabbing force on the upper pressure plate 631.

[0039] Further, if Figure 6 As shown, in order to ensure that the first wire hole 91 on the brush disc 9 to be threaded can be aligned with the material wire when the grabbing mechanism 5 grabs the brush disc 9 to load the material and thread the wire, an alignment mechanism is provided on the material station, and the alignment mechanism includes an alignment drive member 24 and a rotating seat 21 for carrying the brush disc 9. The alignment drive member 24 is a servo motor, and the servo motor is arranged in a mouth-shaped support seat; a positioning hole 92 is opened on the brush disc, and a detection element for detecting the positioning hole 92 is provided on the rotating seat 21. The detection element, the alignment drive member 24, and the rotation seat 21 are provided with a detection element for detecting the positioning hole 92. 4 are all electrically connected to a controller, and the alignment drive member 24 can drive the rotating seat and the brush plate 9 to rotate. When the detection element detects the positioning hole 92, the detection element sends a detection signal to the controller, and the controller controls the alignment drive member 24 to stop rotating according to the detection signal, so that each brush plate 9 is aligned to a predetermined position before loading, so as to avoid the first wire hole 91 of the brush plate 9 being misaligned with the prepared wire 7 when the brush plate 9 is threading the wire; so that each brush plate 9 can be orderly adjusted to a predetermined position before loading, so as to ensure smooth processing of the wire.

[0040] Furthermore, the detection element is an infrared sensor 25; the infrared sensor 25 has low cost and high sensitivity, and can accurately detect the positioning hole 91 on the end face of the brush disc 9; specifically, the infrared sensor 25 always emits a detection light beam that shines on the end face of the brush disc 9. When the rotating seat 21 drives the brush disc 9 to rotate until the positioning hole 91 corresponds to the detection light beam, the detection light beam can feed back a signal of detection positioning to the controller, so that the controller controls the driving component to stop working, so that the brush disc 9 stops at a predetermined position.

[0041] Furthermore, a positioning platform 22 is provided on the rotating seat 21 and protrudes upward and matches the inner hole of the brush plate 9 ; the positioning platform 22 can facilitate the setting of the brush plate 9 and prevent the brush plate 9 from lateral movement on the rotating seat 21 .

[0042] Furthermore, in order to place the brush disc 9 quickly and accurately on the rotating seat, a plurality of guide cones 23 are arranged along the circumferential direction on the upper end surface of the positioning platform 22 and close to the outer periphery; the guide cone 23 is a conical structure that is thin at the top and wide at the bottom. When the brush disc 9 is installed, it can guide the brush disc 9. Even if there is a slight error in the position of the inner hole of the brush disc 9 and the positioning platform 22, the guide cone 23 can guide the brush disc 9 into place through the conical surface, thereby quickly completing the installation and positioning.

[0043] Further, if Figure 3 As shown, after the wire bundle welding is completed, the radial pressure rod 633 of the upper pressure plate 631 and the radial pressure rod 633 of the lower pressure plate 638 are both in an extended state. If they are not reset, it is difficult to compact the stranded wire again when the wire pressing assembly 63 rotates back with the turntable 62 to correspond to the wire seeding mechanism 3. Therefore, in this embodiment, a through hole is set in the middle position of the turntable 62, and a push mechanism 65 independent of the turntable 62 is set in the through hole. The push mechanism 65 includes two extensions spaced up and down and corresponding to the upper pressure plate 631 and the lower pressure plate 638 on the installation position of the hot melt welding mechanism 4 in sequence. Retract the push rod 652; when all the wire bundles on the brush disc 9 are welded and formed, the two telescopic push rods 652 retract and push the corresponding radial pressure rods 633 on the upper pressure plate 631 and the corresponding radial pressure rods 633 on the lower pressure plate 638 to retract radially and return to their original positions. Then, the stepper motor 64 drives the brush disc 9 on the wire pressing assembly 63 to rotate step by step according to a predetermined angle so that the next corresponding radial pressure rod 633 is aligned with the corresponding telescopic push rod 652, alternating back and forth, so that all the radial pressure rods 633 on the upper pressure plate 631 and all the radial pressure rods 633 on the lower pressure plate 638 are all retracted radially and returned to their original positions.

[0044] Further, if Figure 8-14 , Fig.18 As shown, when the wire-seeding mechanism 3 is threading the wire, in order to ensure the threading efficiency, the method of cutting the wire first and then threading the wire is not adopted. Specifically, the support frame 3a is provided with a wire transporting mechanism 33 and a wire clamping mechanism 39 respectively located above and below the brush disc 9. The wire transporting mechanism 33 can transport the prepared wire 7 from top to bottom, and after the prepared wire 7 passes through one of the wire holes 91 of the brush disc 9, a traction section 71 exceeding the lower end surface of the brush disc 9 is formed; the wire clamping mechanism 39 includes a wire clamping driving member and a wire clamping assembly corresponding to the position of the traction section 71. After the wire clamping assembly clamps the traction section 71, the wire clamping driving member drives the wire clamping assembly to move downward to pull the prepared wire 7 downward into place; a wire cutting mechanism 36 is provided between the brush disc 9 and the wire transporting mechanism 33. After the wire clamping mechanism 39 pulls the prepared wire 7 downward into place, the wire cutting mechanism 36 can cut the prepared wire 7, so that the cut wire 8 of a predetermined length is threaded into the wire hole 91 and into place.

[0045] Furthermore, a guide wheel 3b is provided on the support frame 3a, and a plurality of annular guide grooves are provided on the outer circumference of the guide wheel 3b, and a plurality of material wires are located in the guide grooves; the wire transport mechanism 33 includes a wire transport assembly arranged on the support frame 3a, and the wire transport assembly includes a wire transport piece 313, and the wire transport piece 313 is provided with a wire inlet hole 316 which passes through from top to bottom and is used to accommodate the prepared material wire 7. After being guided by the guide groove, the lower end of the prepared material wire 7 passes through the wire inlet hole, and a clamping cylinder 314 is connected to the wire transport piece 313, and the clamping cylinder 314 has a telescopic pressure rod 315 which is inserted into the wire inlet hole 316 and is used to clamp or loosen the prepared material wire 7; there are two wire transport assemblies, including an upper wire transport assembly 31 and a lower wire transport assembly 32 which are sequentially arranged on the support frame 3a, and the upper wire transport assembly 31 is connected to an upper wire transport cylinder 311, and the wire transport piece 313 in the upper wire transport assembly 31 A wire guide rod 312 is connected to the upper part, and a support plate 3a for installing an upper wire cylinder 311 is provided on the top of the support frame 3a. The wire guide rod 312 is slidably connected to the guide hole set in the support plate 3a; and is driven by the upper wire cylinder 311 to move longitudinally along the lower part. When the telescopic pressure rod 315 in the upper wire transport assembly 31 is extended to compress and transport the prepared wire 7 downward, the telescopic pressure rod 315 in the lower wire transport assembly 32 is retracted; when the telescopic pressure rod 315 in the upper wire transport assembly 31 is retracted to loosen the prepared wire 7 and reset it upward, the telescopic pressure rod 315 in the lower wire transport assembly 32 is extended to compress the prepared wire 7, alternating back and forth until the lower end surface of the brush disc 9 forms the traction section 71; the wire transport mechanism 33 can stably transport the prepared wire 7 downward in an alternating manner to ensure that the lower end surface of the brush disc 9 forms the traction section 71.

[0046] The lower wire transport assembly 32 is driven by a lower wire transport cylinder 321 and moves longitudinally. Specifically, a hook plate 322 is provided on the support frame 3a for easy connection. The hook plate 321 is provided on a sliding plate 323. The sliding plate 323 is slidably connected to a longitudinal guide rail 325 provided on the support frame 3a. A hanging hole is provided on the hook plate 322. The piston rod of the lower wire pressing cylinder 321 is connected to the hanging hole. A guide tube 324 extending downward is connected to the wire transport part 313 in the lower wire transport assembly 32. The wire inlet hole 316 on the wire transport part 313 in the lower wire transport assembly 32 is provided on the guide tube 324. The upper wire transport cylinder 311 drives the lower wire transport assembly 32 to move in a longitudinal direction. Before the upper wire transport component 31 is actuated, the telescopic pressure rod 315 in the lower wire transport component 32 extends out and presses the prepared wire 7 in the guide tube 324, and the lower wire transport cylinder 321 drives the lower wire transport component 32 to move downward so that the lower end of the guide tube 324 is aligned with the corresponding wire hole 91 on the brush plate 9; while guiding the wire to pass through the wire hole, the guide tube 324 can limit the wire passing through the wire hole in the tube to prevent the wire passing through the wire hole from spreading outward, and at the same time, the lower wire transport cylinder 321 can drive the wire transport part 313 in the lower wire transport component 32 to move downward, so that the lower end of the prepared wire 7 is at the upper end of the wire hole 91, so as to be ready before the wire transport mechanism 33 starts to transport the wire.

[0047] Furthermore, the structure of the wire cutting mechanism 36 is as follows: the wire cutting mechanism 36 includes a fixed cutter 363 and a movable cutter 361 which are arranged on the support frame 3a and are horizontally opposite to each other. The movable cutter 361 is connected to a wire cutting cylinder 362. When the prepared wire 7 is pulled downward into place by the wire clamping mechanism 39, the wire cutting cylinder 362 drives the movable cutter 361 to approach the fixed cutter 363 to cut the prepared wire 7.

[0048] Furthermore, the structure of the wire clamping mechanism 39 is as follows: the wire clamping mechanism 39 includes a wire clamping seat 396 and a wire clamping assembly, and the driving member is a wire clamping cylinder 395 connected to the lower end of the wire clamping seat 396; the wire clamping assembly includes a first wire clamping member 391 and a second wire clamping member 392 arranged on the wire clamping seat 396, and at least one of the first wire clamping member 391 and the second wire clamping member 392 is connected to a clamping cylinder 393, and the clamping cylinder 393 drives the first wire clamping member 391 and / or the second wire clamping member 392 to move to clamp the traction section 71, and then the wire clamping cylinder 395 drives the wire clamping assembly to move downward to pull the prepared wire 7 downward into place.

[0049] Furthermore, in the present embodiment, one of the first wire clamping member 391 and the second wire clamping member 392 can be connected to the clamping driving member, or the clamping driving member can be connected to both the first wire clamping member 391 and the second wire clamping member, so that the corresponding clamping driving member can work and drive the first wire clamping member 391 and the second wire clamping member 391 to clamp or loosen the traction section 71. In the present embodiment, only one clamping driving member is provided for explanation. Specifically, the first wire clamping member 391 in the present embodiment is a wire clamping block, and the second wire clamping member 392 is a wire clamping rod. The wire clamping block and the wire clamping rod are arranged on a wire clamping seat 396. The clamping driving member is a clamping cylinder 393 connected to the wire clamping block and drives the wire clamping block away from or close to the wire clamping rod; the wire clamping driving member is a wire clamping cylinder 395 arranged at the bottom end of the wire clamping seat 396.

[0050] Furthermore, in order to prevent the traction segment 71 from being deformed and affecting the clamping effect when the wire clamping block and the wire clamping rod clamp the traction segment 71, the wire clamping block is provided with a wire clamping portion for cooperating with the wire clamping rod, and an extension portion spaced from the wire clamping portion, and a strip groove 393 extending longitudinally for accommodating the traction segment 71 is formed between the extension portion and the wire clamping portion; when the traction segment 71 is clamped by the wire clamping assembly, the traction segment 71 remains stable in the strip groove 393.

[0051] Furthermore, the screw rod and the extension part are arranged on the same side. In order to avoid interference between the screw rod and the extension part, a through groove matching the screw rod is provided on the extension part, and the screw rod is inserted in the through groove. When the piston rod of the clamping cylinder 393 is extended, the wire clamping block is away from the screw rod, and the head of the screw rod is retracted into the through groove, so that the traction section 71 enters the strip groove 393; when the piston rod of the clamping cylinder 393 is retracted, the wire clamping block is close to the screw rod, and the head of the screw rod is inserted into the limiting groove to clamp the traction section 71 in the strip groove 393; this design ensures that the wire clamping block can ensure that the screw rod does not interfere with the extension part while setting the extension part, and can cooperate normally with the wire clamping part.

[0052] Further, if Fig.15 , Fig.19 , Fig.25 As shown, after the cut wire 8 enters the wire hole 91, it is necessary to perform wire folding processing. Therefore, a wire folding mechanism corresponding to the brush plate 9 is provided on the support frame 3a. The wire folding mechanism includes a wire folding frame 371 and a driving component for driving the wire folding frame 371 to move horizontally. The head of the wire folding frame 371 is a wire folding end. The wire folding end has a strip groove 375 extending toward the inner side of the wire folding frame 371. The strip groove 375 divides the wire folding end into an upper wire folding portion 375a and a lower wire folding portion 375b. The wire folding frame 371 has a vertically extending groove 375 extending from top to bottom. folding wire cavity; the brush disc 9 is inserted into the strip groove 375, and the corresponding wire hole 91 on the brush disc 9 is in the wire folding cavity; when the cut wire 8 is inserted into the wire hole 91, the cut wire 8 is divided into two strands of wire located on both sides of the brush disc 9, and at this time, the wire clamping mechanism 39 releases the traction section 71, and the driving assembly drives the wire folding frame 371 to move away from the brush disc 9, so that the upper wire folding part 375a and the lower wire folding part 375b overlap the two strands of wire outward into a wire bundle; thereby improving the forming efficiency of the wire bundle.

[0053] Further, the upper push-pull assembly 34 and the lower push-pull assembly 35 extend the radial pressure rod 633 in the following manner: the end surface of the upper pressure plate 631 facing away from the brush plate 9 and the end surface of the lower pressure plate 638 facing away from the brush plate 9 are uniformly distributed along the circumferential direction with a plurality of radial guide grooves 632 connected by radial grooves 631b, and the radial pressure rod 633 is provided with a protrusion 634 that exceeds the end surface of the upper pressure plate 631 facing away from the brush plate 9 or the end surface of the lower pressure plate 638 facing away from the brush plate 9 and is slidably connected to the radial guide groove 632; the upper push-pull assembly includes an upper push-pull rod 341 and an upper push-pull cylinder 342, and the upper push-pull rod 341 is located at the protrusion 634 of the upper pressure plate 631 On the inside, the lower push-pull assembly includes a lower push-pull rod 351 and a lower push-pull cylinder 353, and the lower push-pull rod 351 is on the inner side of the protrusion 634 of the lower pressure plate 638; when the wire folding frame 371 stacks the two strands of wire outward into a wire bundle, the upper push-pull cylinder 342 and the lower push-pull cylinder 353 respectively drive the upper push-pull rod 341 and the lower push-pull rod 351 to move in the direction away from the brush plate 9 and act on the corresponding protrusion 634, so that the corresponding radial pressure rod 633 extends out and presses the two strands of wire against the corresponding end surface of the brush plate 9; after the two strands of wire are stacked into a wire bundle, they remain fixed and do not spread outward, which is convenient for the next step of hot melt welding.

[0054] Further, if Figure 8-9 As shown, a guide assembly is provided in the wire folding cavity, and the guide assembly includes two opposing guide plates 372, one of which is connected to a guide cylinder 374; when the wire transport mechanism 33 transports the prepared wire 7 downward, the piston rod of the guide cylinder 374 extends to bring the two guide plates 372 closer together to form a guide groove 373 for guiding the prepared wire 7 to penetrate into the wire hole 91; when the wire folding frame 371 moves in a direction away from the brush plate 9, the piston rod of the guide cylinder 374 retracts to move the two guide plates 372 away from each other to avoid the outwardly overlapped stranded wire; the guide assembly of this embodiment, while guiding the wire to penetrate into the wire hole, takes into account the problem of the guide plate avoiding the stranded wire when folding the wire, thereby controlling one of the guide plates 372 to move by the guide cylinder 374, effectively preventing the two stranded wires from interfering with the guide plate 372 when folded in half.

[0055] Furthermore, when the guide assembly is arranged in the wire folding cavity, the guide plate 372 is easy to interfere with the brush plate 9. Therefore, the two guide plates 372 in this embodiment are provided with avoidance grooves (not shown) corresponding to the strip grooves 375 and used to avoid the brush plate 9; the avoidance grooves divide the entire guide plate 372 into two guide support plates. The avoidance grooves can prevent the guide plate 372 from interfering with the brush plate inserted into the strip grooves 375, so that the wire folding can be carried out smoothly.

[0056] Further, if Fig.25As shown, the structure of the wire folding mechanism 37 is as follows: a linkage assembly is provided on the wire folding mechanism 37, and the linkage assembly includes a first support plate 374a and a second support plate 374b which are sequentially away from the wire folding frame 371, a first cross bar 377 is connected between the first support plate 374a and the second support plate 374b, and the wire folding frame 371 is arranged on the first support plate 374a; a driving assembly includes a first driving cylinder 376 and a second driving cylinder 379 which act on the second support plate 374b, the piston rod of the first driving cylinder 376 is retracted and drives the wire folding frame 371 to move in a radial direction away from the brush plate 9, so as to make room for the radial pressure rod 633 to extend radially; when the radial pressure rod 633 is extended and presses the divided wire, the piston rod of the second driving cylinder 379 is extended. The wire folding frame 371 is retracted and driven to continue moving in the direction away from the brush plate 9, so that the wire folding frame 371 is completely separated from the wire bundle; the first driving cylinder 376 and the second driving cylinder 379 can form a step-by-step drive for the second support plate 374b to compensate for the response time difference between the driving component and the upper push-pull cylinder 342 and the lower push-pull cylinder 353, so that when the piston rod of the first driving cylinder 376 is extended and retracted to make room for the corresponding radial pressure rod 633, the two strands of wire are still stuck in the strip groove 375 instead of spreading outwards. After the radial pressure rod 633 compresses the strands of wire, the piston rod of the second driving cylinder 376 is extended and retracted to completely separate from the formed wire bundle, ensuring that after the wire folding mechanism 37 folds the wire, the corresponding movable pressure rod 633 can smoothly compress the wire bundle.

[0057] Furthermore, since the wire hole 91 of the brush disc 9 is close to the outer peripheral edge of the brush disc 9, the two strands of wire can be folded in half to form a wire bundle that exceeds the outer periphery of the brush disc, and after the wire bundle is formed, the length of the stranded wire attached to the end surface of the brush disc 9 is smaller than the length of the stranded wire exceeding the brush disc 9. Therefore, to correspond to these two lengths, the telescopic stroke of the piston rod of the first drive cylinder 376 is smaller than the telescopic stroke of the piston rod of the second drive cylinder 379. Specifically, when the piston rod of the first drive cylinder 376 is telescoped and drives the wire folding frame 371 to move in a radial direction away from the brush disc 9 and make room for the movable pressure rod 633 to extend radially, the wire folding end only needs to just leave the end surface of the brush disc 9, so the movable range of the wire folding frame 371 is shorter at this time; afterwards, the wire folding frame 371 needs to be completely separated from the wire bundle, and the required movable range is longer, so the telescopic length of the piston rod of the second drive cylinder 379 is longer.

[0058] Furthermore, if the first driving cylinder 376 and the second driving cylinder 379 are arranged side by side to drive the wire folding frame 371 in steps, then when the first driving cylinder 376 or the second driving cylinder 379 is extended or retracted, the piston rod of the other cylinder will inevitably be driven to move, affecting the smoothness of the movement of the wire folding frame 371. Therefore, in order to meet the purpose of driving the wire folding frame 371 in steps, the first driving cylinder 376 is arranged on the first support plate 374a, and the second driving cylinder 379 is arranged on the first longitudinal plate 378 close to the side of the first support plate 374a, and the piston rod of the first driving cylinder 376 and the piston rod of the second driving cylinder 379 are opposite and connected together; specifically, there is a shaft sleeve between the piston rod of the first driving cylinder 376 and the piston rod of the second driving cylinder 379, and the piston rod of the first driving cylinder 376 and the piston rod of the second driving cylinder 379 are inserted into the shaft sleeve and locked by screws; thereby, while satisfying the step-by-step drive of the wire folding frame 374, the layout space of the driving component is saved.

[0059] Further, if Figure 16-17 As shown, at the outer peripheral position of the pressure plate, a limiting portion 631a is formed between every two adjacent radial grooves 631b, and the movable pressure rod 633 has two opposite side extensions 633a on both sides. When the movable pressure rod 633 is retracted, the two side extensions 633a are abutted against the corresponding limiting portions 631a to prevent the entire movable pressure rod 633a from being completely retracted into the radial groove 631b.

[0060] Furthermore, the bottom end of the movable pressure rod 633 has a limiting groove 635. After the movable pressure rod 633 is extended, the stranded wire is within the limitation of the limiting groove 635, thereby preventing the stranded wire from spreading to both sides.

[0061] Furthermore, a plurality of weight-reducing grooves 631 c are provided on the end surface of the pressure plate and are evenly distributed along the circumferential direction, so as to reduce the structure of the entire pressure plate 631 .

[0062] Further, if Figure 7 As shown, in order to prevent the brush plate 9 from moving circumferentially on the wire pressing assembly, the lower pressure plate 638 has a positioning protrusion 631d on the end face facing the upper pressure plate 631, and the brush plate 9 has a positioning notch 93 on the end face matching the positioning protrusion 631d, and the positioning protrusion 631d is stuck in the positioning notch 93.

[0063] Furthermore, in order to prevent the upper pressure plate 631 and the lower pressure plate 638 from moving relative to each other in the circumferential direction, a pin hole corresponding to the position of the positioning protrusion 631d is provided on the end surface of the upper pressure plate 631 facing the lower pressure plate 638, and the positioning protrusion 631d is inserted into the pin hole.

[0064] Furthermore, the specific structure of the upper push-pull assembly 34 is as follows: a horizontal plate 343 for installing the upper push-pull assembly 34 is provided on the frame 3, and a avoidance hole 344 for avoiding the guide tube 324 is provided on the horizontal plate 343. The upper push-pull assembly 34 includes a first vertical plate 346 arranged on the support frame 3, and the upper driving member is an upper push-pull cylinder 342 connected to the first vertical plate 346. The piston rod of the upper push-pull cylinder 342 is connected to the upper push-pull member 341; in order to ensure the smooth movement of the upper push-pull rod 341, a first vertical plate 346 is provided for installing A connecting plate 345 of the push-pull member 341 is installed, and a second guide assembly is provided between the connecting plate 345 and the first vertical plate 346. The second guide assembly includes a second cross bar 344. The connecting plate 345 is provided with a second guide hole matching the second cross bar 344. The second guide holes are symmetrically arranged on the connecting plate 345, and the number and position of the second cross bar 344 match those of the second guide holes. One end of the second cross bar 344 acts on the push-pull member 341, and the other end penetrates into the second guide hole, thereby providing a movable guide for lifting the push-pull member 341.

[0065] Further, if Fig.26 As shown, the specific structure of the lower push-pull component 35 is as follows: the lower push-pull component 35 includes two mounting plates 352 arranged at intervals on the support frame 3, and a third cross bar 355 is connected between the two mounting plates 352; the lower push-pull member 351 is installed on the mounting plate 352 on the side close to the wire folding frame 371, and the second driving member is a lower push-pull cylinder 353 acting on the mounting plate 352 on the side away from the wire folding frame 371; to ensure smooth movement of the lower push-pull rod 351, a second vertical plate 354 for mounting the lower push-pull cylinder 353 is provided on the support frame 3, and a third guide hole for sliding cooperation with the third cross bar 355 is provided on the second vertical plate 354; the third guide holes are symmetrically arranged on the second vertical plate 354, and the number and position of the third cross bar 355 match the third guide holes; to guide the lifting activity of the lower push-pull member 351.

[0066] Furthermore, the wire holes 91 on the brush plate 9 that have not been threaded with wire are divided into wire holes to be fed, and the wire holes 91 that have been threaded with wire are divided into wire holes that have been threaded with wire. After the corresponding wire holes 91 on the brush plate 9 are seeded with wire, a wire bundle will be formed at the wire holes 91 that have been threaded with wire. The wire bundle itself has elasticity, so it is easy to fork to the side of the wire hole 91 that has not been threaded with wire. When the forked wire is folded in the next wire hole 91, it is easy to be rolled into the next wire bundle to be formed by the wire folding frame 371. Therefore, the wire seeding mechanism 3 in this embodiment is provided with a wire drawing mechanism 38, such as Figure 27-30As shown, the wire drawing mechanism 38 includes a movable lever 381 and a rotating shaft 382 extending in the longitudinal direction, and a wire drawing driving member is connected to the rotating shaft 382, ​​and the rotating shaft 382 is connected to the movable lever 381 through a linkage rod 383; when the two strands of wire in one of the wire holes 91 on the brush plate 9 are superimposed into a wire bundle, the upper pressure plate 631 and the lower pressure plate 638 rotate and make the next wire hole 91 of the brush plate 9 align with the prepared wire 7 for re-threading, the wire drawing driving member drives the rotating shaft 382 to rotate, and links the movable lever 381 to move between the adjacent wire holes 91 that have been threaded and the wire holes 91 that have not been threaded on the brush plate 9, so as to draw the wire bundle at the position of the threaded wire hole 91 along the circumferential direction of the brush plate 9; so that the wire bundle at the threaded wire hole will not fork to the side of the wire hole that has not been threaded, to ensure that the wire bundle on the side of the threaded wire hole will not be rolled into the next wire bundle to be formed.

[0067] Furthermore, the specific structure of the wire drawing mechanism 38 is as follows: the wire drawing driving member can be directly connected to the rotating shaft 1 to drive the movable lever 381 to move, or the driving member can be indirectly connected to the rotating shaft 1 through a transmission assembly; in this embodiment, the rotating shaft 382 is arranged on a wire drawing seat 386, and the wire drawing seat 386 is provided with a transmission assembly, the transmission assembly includes a transmission rod 388 slidably connected to the wire drawing seat 386, and the transmission rod 388 is provided with a plurality of tooth grooves 389. A swinging tooth member 387 is fixedly connected to the shaft body of the rotating shaft 1, and the swinging tooth member 387 has a plurality of tooth portions 387a matching the tooth grooves 389. The driving member is a wire drawing cylinder 384, and the piston rod of the wire drawing cylinder 384 is indirectly connected to the transmission rod 388 through a transition connecting plate 385. The piston rod of the wire drawing cylinder 384 can be extended and retracted to drive the transmission rod 388 to slide on the wire drawing seat 386, so that the tooth grooves 389 cooperate with the tooth portions 387a to drive the rotating shaft 1 to rotate.

[0068] Furthermore, compared with providing a standard tooth-shaped groove on the rod body of the transmission rod 388, the transmission rod 388 in this embodiment has lower cost and is easier to process, that is, the transmission rod 388 is a screw rod, and the tooth groove 389 is a spiral groove arranged on the screw rod; compared with providing a standard tooth-shaped groove on the transmission rod 388, directly using a screw rod with a spiral groove has lower cost, and at the same time can also ensure the meshing effect of the tooth groove 389 and the tooth portion 387a.

[0069] Furthermore, the volume of the wire drawing mechanism 38 needs to be miniaturized, and the miniaturized wire drawing mechanism 38 is easier to install. Therefore, in this embodiment, a accommodating chamber 3861 is provided on the wire drawing seat 386, and the rotating shaft 1 has a matching portion penetrating the accommodating chamber 3861, and the swinging tooth 387 is fixedly connected to the matching portion. The side wall of the accommodating chamber 3861 is provided with a sliding guide hole 3862 connected to the outside, and the transmission rod 388 is slidably connected in the sliding guide hole 3862; the accommodating chamber 3861 can accommodate the transmission assembly in the wire drawing seat 386, reduce the space it occupies in the wire drawing mechanism, optimize the structural layout of the wire drawing mechanism, and facilitate the installation of the wire drawing mechanism to the corresponding position for wire drawing work.

[0070] Furthermore, the connection relationship between the transition connecting plate 385, the transmission rod 388, and the wire drawing cylinder 384 is as follows: the transition connecting plate 385 is provided with a connecting sleeve inserted into the sliding guide hole 3862, and the end of the transmission rod 388 is provided with a screw hole corresponding to the position of the connecting sleeve. The screw passes through the connecting sleeve and is screwed into the screw hole to connect the transmission rod 388 to the transition connecting plate 385; a threaded rod is connected to the piston rod of the wire drawing cylinder 384, and an internal threaded sleeve corresponding to the threaded rod is connected to the transition connecting plate 385. After the threaded rod and the internal threaded sleeve are matched, they are locked by a nut to connect the piston rod to the transition connecting plate 385.

[0071] Furthermore, when multiple wire holes for waiting material are threaded and folded one by one, it is only necessary to control the movable lever 381 to pull the wire bundles at the adjacent already threaded holes together. However, when the last wire hole for waiting material is threaded and folded, the wire holes on both sides of the last wire hole for waiting material have been threaded and formed into wire bundles, so another lever is required to cooperate with the movable lever 381; the wire pulling mechanism 38 in this embodiment also includes a fixed lever 38a adjacent to the movable lever 381; when the support shaft 636 rotates and the last wire hole for waiting material on the brush plate 9 is threaded, wire bundles are formed in the two already threaded holes adjacent to the wire hole for waiting material, and the wire pulling drive member drives the rotating shaft 382 to rotate, so that the movable lever 381 moves between one of the already threaded holes and the wire hole for waiting material, and pulls the wire bundle on one side of one of the already threaded holes together. At this time, the fixed lever 38a is between the other already threaded hole and the wire hole for waiting material, and pulls the wire bundle on the other side of the already threaded hole together.

[0072] Furthermore, when the fixed wire bundle is welded, since the wire bundle is composed of multiple separate elastic wires, the welding head 41 will exert a squeezing force on the wire bundle when it is lowered, which may easily cause the multiple wires to spread to both sides or bend upward, resulting in an unreliable welding. Figure 4-5As shown, the hot melt welding mechanism 4 in the present invention includes a welding auxiliary mechanism that cooperates with the welding head 41, and the welding auxiliary mechanism includes an auxiliary power component and a positioning component. The positioning component includes a pressing plate 424 and a positioning rod 421a arranged in sequence from top to bottom. The top of the positioning rod 421a has two opposite side portions 421b, and a constraint groove 421c for accommodating a wire bundle and corresponding to the position of the welding head 41 is formed between the two side portions 421b; the auxiliary power component includes a plurality of driving units that respectively drive the positioning rod 421a and the pressing plate 424 to move along the positioning rod 421a. A first driving member 421 and a second driving member 423 are longitudinally movable; the first driving member 421 drives the positioning rod 421a to move upward to approach the wire bundle, and the second driving member 423 drives the pressure plate 424 to move downward to press the wire bundle into the constraint groove 421c, so that the wire bundle can remain stable in the constraint groove 421c when the welding head 41 is welding; when the welding is completed, the first driving member 421 drives the positioning rod 421a to move downward, and the second driving member 423 drives the pressure plate 424 to move upward, so that the wire bundle can escape from the constraint groove 421c.

[0073] Furthermore, the installation layout of the positioning assembly and the power assembly is as follows: the wire welding auxiliary mechanism also includes a base, the first driving member 421 is a first cylinder installed on the base, the first cylinder has a first piston rod that is telescopic along the longitudinal direction and connected to the positioning rod 421a; the first cylinder is sensitive and fast in telescopic extension, and can drive the positioning rod 421a to quickly telescope; in order to avoid interference with the first cylinder, a horizontal plate 426 separated from the base is installed on the cylinder body of the first cylinder, and the second driving member 423 is installed on the horizontal plate 426 and connected to the first cylinder The second cylinder is staggered in position, and the second cylinder has a second piston rod that is telescopic in the longitudinal direction. An extension plate 424a is installed on the second piston rod. The extension plate 424a is connected to the pressure plate 424 so that the position of the pressure plate 424 corresponds to the top position of the positioning rod 421a; when welding the wire bundle, the pressure plate 424 needs to be close to the constraint groove 421c to facilitate pressing the wire bundle. The extension plate 424a can make up for the distance that the second cylinder is staggered from the first cylinder due to the spatial layout, so that the pressure plate 424 corresponds to the position of the constraint groove 421c, thereby stably pressing the wire bundle.

[0074] Furthermore, in order to stably compress the wire bundle when the welding head 41 is working, the pressing plate 424 will compress the upper surface of the wire bundle, but completely compressing the upper surface of the wire bundle will cause the welding head 41 to interfere with the pressing plate 424. Therefore, in this embodiment, the pressing plate 424 is provided with an avoidance opening 425 corresponding to the position of the constraint groove 421c and used to avoid the welding head; the avoidance opening 425 provides a welding avoidance space to avoid interference between the welding head 41 and the pressing plate 424, so that the welding head 41 can pass through the avoidance opening 425 to weld the wire bundle.

[0075] Furthermore, in order to ensure smooth up and down movement of the positioning rod 421a, a first guide assembly is installed on the transverse plate 426. The transverse plate 426 is a mounting carrier of the second cylinder and also a mounting carrier of the first guide assembly. The first guide assembly includes two support rods symmetrically arranged on the transverse plate 426. The top ends of the two support rods are connected to a first guide plate 422. The first guide plate 422 is provided with a guide groove corresponding to the position of the positioning rod 421a. The positioning rod 421a moves longitudinally in the guide groove 31, so that the wire welding auxiliary mechanism switches between a working state and a reset state; the guide groove on the first guide plate 422 can provide guidance for the positioning rod 421a; so that when the wire welding auxiliary mechanism is in a working state, the upper end of the positioning rod 421a exceeds the upper end of the first guide plate 422; when the wire welding auxiliary mechanism is in a reset state, the upper end of the positioning rod 421a will retract downward into the guide groove, which will not affect the movement of the next wire bundle on the brush plate to the corresponding welding position.

[0076] Furthermore, in order to enable the pressure plate 424 to move up and down without being displaced, a second guide assembly is installed on the cylinder body of the second cylinder, and the second guide assembly includes a second guide plate 424c installed on the cylinder body of the second cylinder, and guide holes are symmetrically opened on the second guide plate 424c, and a second guide rod 424b connected to the extension plate 424a is slidably connected in the guide hole; the second guide rod 424b cooperates with the guide hole to form a moving guide for the pressure plate 244 and the extension plate 424a.

[0077] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
