Description

Technical Field

[0001] This invention relates to the field of piano linkage processing technology, and in particular to a felt perforation device. Background Technology

[0002] The piano is a keyboard instrument, available in upright and grand styles. It possesses a unique full-range and has always been a favorite of composers. Playing a vital role in almost all genres of music, including pop, rock, jazz, and classical, it is hailed as the "King of Instruments." The piano boasts the most complex structure of any musical instrument, composed of over 8,000 parts. Its main raw materials include wood, metal, felt, plastics, and chemical materials (coatings, adhesives). Felt is particularly important in the piano's action mechanism, used in components such as hammers, tuning pegs, keys, dampers, linkages, action mechanisms, and adjusters. Its primary function is to strike the strings to produce sound and to cushion and eliminate unwanted noise. Therefore, felt is an indispensable material in the piano and a crucial component placed in a key location.

[0003] In the piano linkage, the linkage rod and the top pin are connected by a pin shaft to achieve a rotational connection between the linkage rod and the top pin. In actual use, in order to improve the service life of the linkage and avoid damage to the linkage rod due to long-term rotational friction between the linkage rod and the pin shaft, a felt should be inserted into the connection hole between the linkage rod and the top pin before the pin shaft is installed into the linkage rod and the top pin. This reduces the friction between the pin shaft and the linkage rod and eliminates the noise caused by the friction between the linkage rod and the pin shaft.

[0004] Traditional methods of threading felt into the linkage rod holes are mostly semi-automated. The felt is placed manually on the linkage rod, then pressed in by an external mechanical structure, and finally glue is applied to the felt insertion point on the linkage rod. Because the linkage rod requires double-sided threading and glue application, each threading step requires two manual operations and two glue applications. Furthermore, since the felt is a relatively thin layer of fabric, threading is prone to failure or even tearing, preventing the felt from being fully inserted into the linkage rod. This necessitates re-threading, causing significant inconvenience, resulting in low efficiency, a low yield rate, increased production costs, and high labor intensity.

[0005] Based on this, a felt perforation device is proposed, providing a new solution to the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0056] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0057] Please refer to Figure 1-19 A felt perforation device, comprising a workbench 100;

[0058] The linkage rod feeding module 200 is used to feed the linkage rod. It includes a linkage rod vibrating feeding plate 201 installed at one end of the workbench 100. A cutting component is installed at the output end of the linkage rod vibrating feeding plate 201.

[0059] The conveying module 300 is used to convey the linkage rod, and includes a conveying component installed on one side of the output end of the vibration loading tray 201 of the linkage rod and a material picking and placing component installed on the conveying component;

[0060] The felt perforation module 400 is used to insert felt into the linkage rod. It includes a felt perforation assembly installed on the top of the workbench 100 and located on one side below the conveying assembly, and a felt feeding assembly located on the side of the felt perforation assembly away from the conveying assembly.

[0061] The dispensing module 500 is used to dispense adhesive to the felt-through part of the linkage rod. It includes a dispensing and cutting assembly located on the top of the workbench 100 and at the end of the felt-through assembly away from the vibrating feeding plate 201 of the linkage rod, and a dispensing assembly located on the dispensing and cutting side.

[0062] The conveying module 600 is used to convey and collect the linkage rods after dispensing.

[0063] Specifically, the conveying module 300 transports the linkage rods, the felt perforation module 400 feeds the felt and inserts it into the inside of the linkage rods, the glue dispensing module 500 dispenses glue and dries it onto the linkage rods, and the conveying module 600 conveys and collects the linkage rods. This achieves automated felting, greatly improving production efficiency, reducing manual labor, and facilitating mass production. The equipment integrates feeding, handling, felting, glue dispensing, and unloading into one unit, with a high degree of automation. The overall structure is compact and simple, reducing space occupation and production costs.

[0064] Please refer to Figure 1-3A first support frame 202 is fixed below the output end of the linkage rod vibrating feeding plate 201. The first support frame 202 is fixed on the top of the workbench 100. The cutting assembly includes a cutting cylinder 203 installed on the top of the first support frame 202 and located on one side of the output end of the linkage rod vibrating feeding plate 201. A cutting plate 204 is fixed at the output end of the cutting cylinder 203. The cutting plate 204 is set at the outlet of the output end of the linkage rod vibrating feeding plate 201. A material picking groove 205 is opened on the inner side of the cutting plate 204. Specifically, the linkage rod is fed by the linkage rod vibrating feeding plate 201, and the linkage rod is blocked and cut by the cutting plate 204. The material picking groove 205 provides space for the picking fingers to move. When it is necessary to pick up the linkage rod, the picking fingers first insert into the inside of the picking groove 205, and then the cutting cylinder 203 is started to drive the cutting plate 204 to move downward, so that the linkage rod can be taken out.

[0065] A first mounting bracket 206 is fixed to the side of the first support frame 202 away from the cutting cylinder 203. A first clamping cylinder 207 is mounted on the top of the first mounting bracket 206. A first pressure plate 208 is connected to the output end of the first clamping cylinder 207. The first pressure plate 208 is slidably connected to the first mounting bracket 206. A first clamping head 209 is fixed to the bottom of the first pressure plate 208. The first clamping head 209 is located above the output end of the linkage rod vibrating feeding plate 201. In use, the output end of the linkage rod vibrating feeding plate 201 is... Before the linkage rod is removed, the first clamping cylinder 207 will start, driving the first pressure plate 208 and the first clamping head 209 to move downward, so that the first clamping head 209 presses down on the linkage rod behind, preventing it from continuing to feed material. When the linkage rod at the end of the linkage rod vibrating feeding plate 201 is removed, the first clamping cylinder 207 will start again, causing the first clamping head 209 to release the linkage rod behind. At this time, the linkage rod continues to move forward to the material picking position under the action of the linkage rod vibrating feeding plate 201 and is blocked by the cutting plate 204.

[0066] Please refer to Figure 4-6The conveying assembly includes several second mounting brackets 301 fixed to the top of the workbench 100 and located on the side of the cutting cylinder 203 away from the first mounting bracket 206. A linear motion module backplate 302 is fixed to the top of each of the second mounting brackets 301. First pulleys 304 are rotatably connected to both ends of the inner side of the linear motion module backplate 302. A first transmission belt 305 is connected to the outer sides of the two first pulleys 304. A conveying drive motor 303 is mounted on one side of the top of the linear motion module backplate 302. The output of the conveying drive motor 303... The first drive belt 305 has a fixed connection to the back plate 302 of the linear motion module and is fixedly connected to the first pulley 304 located at the same end. The first drive belt 305 has a fixed connection to the transport and installation slider 306. The transport and installation slider 306 is slidably connected to the back plate 302 of the linear motion module. When in use, the transport drive motor 303 is started, which drives the first drive belt 305 to move through the first pulley 304, thereby driving the transport and installation slider 306 to perform displacement movement. In this embodiment, the transport drive motor 303 is a servo motor to improve the transport accuracy.

[0067] Please refer to Figure 4-6 The material handling assembly includes a first mounting plate 307 fixed to the side of the transport mounting slider 306 near the first support frame 202. Transport lifting cylinders 308 are fixedly mounted at both ends of the first mounting plate 307 away from the transport mounting slider 306. Material handling cylinders 309 are fixedly mounted at the output ends of the transport lifting cylinders 308. The material handling cylinders 309 at both ends are perpendicular to each other. The material handling cylinder 309 near the vibrating feeding plate 201 of the linkage rod is installed vertically, while the material handling cylinder 309 away from the vibrating feeding plate 201 of the linkage rod is installed horizontally. Grippers 310 are fixedly connected to the output ends of the material handling cylinders 309. A material-picking finger is provided on one side. Specifically, the material-picking and unpicking component at the end near the vibrating feeding plate 201 of the linkage rod is used to pick up and carry the linkage rod from the output end of the vibrating feeding plate 201 of the linkage rod. The material-picking and unpicking component at the end away from the vibrating feeding plate 201 of the linkage rod is used to pick up and carry the linkage rod after it has been threaded into the inner side of the felt perforation module 400. When picking up material, the material-picking and unpicking cylinder 309 is activated to drive the two grippers 310 to move towards each other to grip the linkage rod. When unloading material, the material-picking and unpicking cylinder 309 moves away from each other and lowers the linkage rod. At the same time, when it is necessary to adjust the lifting and lowering of the material-picking and unpicking cylinder 309, the lifting and moving cylinder 308 can be activated.

[0068] Please refer to Figure 4-6Since the linkage rod is always gripped by the gripping fingers on the gripper 310 when picking up or putting down materials, and the gripping fingers are located on one side of the picking and putting cylinder 309, after a long period of use, the force imbalance at both ends of the gripper 310 may lead to a decrease in its gripping accuracy and reduce the service life of the picking and putting cylinder 309. Therefore, in this embodiment, a balancing mounting strip 311 is fixed to the end of the gripper 310 away from the gripping fingers. A force balance adjusting screw 312 is provided on the inner side of the balancing mounting strip 311. The force balance adjusting screw 312 is used to balance the force on the gripper 310 when picking up materials. The force balance adjusting screw 312 moves with the movement of the gripper 310. When the gripping fingers grip the linkage rod, the two force balance adjusting screws 312 also abut against each other, thereby balancing the force at both ends of the gripper 310 and improving the service life of the picking and putting cylinder 309.

[0069] It should be noted that, in this embodiment, the force balance adjusting screw 312 is detachably mounted on the balance mounting strip 311, and the length of the force balance adjusting screw 312 extending out of the balance mounting strip 311 is adjustable. The force balance adjusting screw 312 includes a bolt post and a nut. The bolt post is threadedly connected to the balance mounting strip 311, so that the position of the force balance adjusting screw 312 can be adjusted by rotating the bolt post. The nut cooperates with the bolt post to prevent the force balance adjusting screw 312 from loosening.

[0070] Please refer to Figure 7-15 The felt perforation assembly includes a second mounting plate 401 fixed on the top of the workbench 100 and located below the end of the first mounting plate 307 away from the vibrating feeding tray 201 of the linkage rod. A third mounting plate 402 is fixed in the middle of the side of the second mounting plate 401 away from the conveying module 300. A second pressing cylinder 413 is installed on the top of the third mounting plate 402 near the second mounting plate 401. A second pressing head 414 is fixed at the output end of the second pressing cylinder 413. In actual use, the second pressing cylinder 413 can drive the second pressing head 414 to move up and down when it is started.

[0071] First threading vertical plates 403 are fixed at both ends of the bottom side of the third mounting plate 402 near the second mounting plate 401. The first threading vertical plates 403 are fixedly connected to the top of the second mounting plate 401. A second threading vertical plate 404 is fixed at one end of the two first threading vertical plates 403 that are close to each other. A perforation and feeding fixture 405 is slidably connected between the two second threading vertical plates 404. Several guide rods 406 are fixed at the bottom of the perforation and feeding fixture 405. A return spring 407 is sleeved on the bottom of the outer side of the guide rod 406 and the top of the inner side of the worktable 100. The two ends of the return spring 407 are respectively connected to the guide rod 406 and the worktable 100. The perforation and feeding fixture 405 is used to carry the linkage rod that needs to be threaded. When the conveying module 300 moves the linkage rod on the inner side of the vibration loading plate 201 to above the perforation and feeding fixture 405, the conveying lifting cylinder 308 is activated to lift the linkage rod. The linkage rod is placed on the perforation and feeding fixture 405 and then retracted. Subsequently, the second pressing cylinder 413 is activated, driving the second pressing head 414 to move downwards, pressing the linkage rod on the perforation and feeding fixture 405 and causing the perforation and feeding fixture 405 to descend to the bottom of the felting position, thus preparing for felting. When the perforation and feeding fixture 405 descends, the return spring 407 will be stretched. After the felting is completed, the second pressing cylinder 413 is activated, driving the second pressing head 414 to rise, releasing the linkage rod. At this time, the perforation and feeding fixture 405 and the linkage rod are reset under the action of the return spring 407, and the perforation and feeding fixture 405 and the linkage rod are driven to rise to the appropriate position for the next process of picking up and feeding materials. The setting of the second felting vertical plate 404, the first felting vertical plate 403, and the perforation and feeding fixture 405 makes the position of the linkage rod during felting more stable, improving the stability of felting.

[0072] It should be noted that the perforation and feeding fixture 405, as a fixture for threading the linkage rod, has a threading receiving groove and a feeding groove on its top. The receiving groove is used to receive the protruding part of the linkage rod that needs to be threaded. In actual use, a reinforcing plate can be set inside the receiving groove so that after the linkage rod is placed on the perforation and feeding fixture 405, the protruding part that needs to be threaded is precisely engaged with the outside of the reinforcing plate. This protects the threading part of the linkage rod and prevents the threading protruding part from breaking due to the force of the threading needle 410 during the threading process, which would lead to threading failure and defective products. The function of the feeding groove is to provide space for the picking fingers to move, making it easier for the picking fingers to enter and exit, so that the picking fingers can place the linkage rod on the perforation and feeding fixture 405 and exit smoothly.

[0073] On the other hand, the first threading vertical plate 403 has a groove corresponding to the picking finger, which makes it easy for the picking finger to fall directly into the corresponding groove and thus lower the linkage rod. At the same time, the cooperation between the groove and the picking finger plays a role in positioning the linkage rod, making the positioning of the linkage rod more accurate, thereby improving the threading accuracy and the yield rate.

[0074] The inner side of the first fabric threading vertical plate 403 is provided with a fabric threading guide block 411, and the inner side of the second fabric threading vertical plate 404 is provided with a fabric threading extrusion forming block 412. Both the fabric threading guide block 411 and the fabric threading extrusion forming block 412 are fixedly connected to the second mounting plate 401. The inner side of the fabric threading guide block 411 is provided with a needle hole. Fabric threading cylinders 408 are installed at both ends of the top of the second mounting plate 401. The output end of the fabric threading cylinder 408 is fixedly connected to a fabric threading connecting rod 409. The fabric threading connecting rod 409 is slidably connected to the second mounting plate 401. A needle 410 is fixed at one end of the fabric threading connecting rod 409 near the fabric threading guide block 411. The needle 410 and the central axis of the needle hole are connected... The threads are collinear, and the needle 410 passes through the needle hole and is slidably connected to it. Specifically, the threading guide block 411 serves as a guide block for the needle 410, enabling it to thread smoothly. In use, the fabric is compressed inside the threading extrusion forming block 412, forming it into a cylindrical shape. Then, the compressed fabric is threaded into the inside of the linkage rod through the needle 410. Specifically, when the second pressing head 414 presses the linkage rod and the piercing and feeding fixture 405 into the bottom of the second threading vertical plate 404, the hole to be threaded on the linkage rod, the needle hole inside the threading guide block 411, and the central axis of the needle 410 are all on the same straight line to facilitate threading.

[0075] In this embodiment, the design of the felt perforation assembly enables simultaneous felting of both sides of the linkage rod, greatly improving the felting efficiency.

[0076] Please refer to Figure 7-15 The felt feeding assembly includes a fourth mounting plate 415 fixed to the top of the workbench 100 and located on the side of the second mounting plate 401 away from the transport module 300. A first felt feeding cylinder 416 is mounted on the top of the fourth mounting plate 415 away from the third mounting plate 402. A felt feeding block 417 is fixedly connected to the output end of the first felt feeding cylinder 416. A felt feeding guide block 418 is fixed to the top of the fourth mounting plate 415. The felt feeding block 417 is slidably connected to the inner side of the felt feeding guide block 418. A fifth mounting plate 419 is fixed to the top of the felt feeding guide block 418 near the third mounting plate 402. A cutting cylinder 420 is fixed, and cutting blades 421 are fixed at the output end of the cutting cylinder 420 and on both sides of the feeding block 417. The feeding guide block 418 is provided with a felt feeding mechanism on both sides. When in use, after the felt enters the inner side of the end of the feeding block 417, the cutting cylinder 420 is started to drive the cutting blades 421 to move downward, and the felt is cut by the cutting blades 421. The first feeding cylinder 416 is started to drive the feeding block 417 to move horizontally, so that it feeds the felt into the inner side of the extrusion forming block 412. The feeding block 417 and the extrusion forming block 412 approach each other to squeeze the felt, thereby completing the felt feeding work.

[0077] Please refer to Figure 7-15 The felt feeding mechanism includes a third felt feeding frame 422 fixed on both sides of the felt feeding guide block 418. A felt bending block 424 is fixed at one end of the third felt feeding frame 422 near the third mounting plate 402. A felt conveying groove is opened on the inner side of the felt bending block 424. A second felt feeding roller 423 is rotatably connected to the inner side of the end of the third felt feeding frame 422 away from the felt feeding guide block 418. A second felt feeding frame 429 is fixed at the top of the workbench 100 and on one side of the third felt feeding frame 422. A first felt feeding roller 430 is rotatably connected to the second felt feeding frame 429. A first felt feeding frame 428 is fixed at the top of the inner side of the workbench 100 and below the third felt feeding frame 422.

[0078] The fourth mounting plate 415 is topped and located on both sides of the cutting cylinder 420. The output end of the second feeding cylinder 425 is fixedly mounted with a third feeding cylinder 426. The output end of the third feeding cylinder 426 is fixedly mounted with a feeding head 427. The feeding head 427 is provided with multiple feeding teeth at one end near the fabric bending block 424. The feeding head 427 is located on one side of the corresponding felt conveying groove.

[0079] In use, the rolled felt is installed on the first feeding frame 428, and the free end of the felt is sequentially wrapped around the first feeding roller 430 and the second feeding roller 423. Then, it passes through the felt conveying groove of the felt bending block 424 and enters the inner side of the feeding block 417. The felt is in a straight state before entering the felt conveying groove of the felt bending block 424. After entering the felt conveying groove of the felt bending block 424, the upper and lower ends of the felt are rolled towards the middle to prepare for the compression of the felt. At the same time, the friction between the rolled felt and the felt bending block 424 increases, which is conducive to the smooth feeding of the felt. When the felt between the felt bending block 424 and the feeding block 417 is cut by the cutting blade 421, the first feeding cylinder 416 is activated to send the felt into the threading part for threading. Then, the first feeding cylinder 416 resets, and the end of the feeding block 417 returns to the vicinity of the cut felt. After that, the third feeding cylinder 426 starts, driving the feeding head 427 to move and press the felt inside the bending block 424. Then, the second feeding cylinder 425 starts, driving the third feeding cylinder 426 and the feeding head 427 to move towards the feeding block 417. At the same time, the felt inside the bending block 424 moves with the feeding head 427, thus conveying the felt inside the bending block 424 back to the inside of the feeding block 417. After the cutting blade 421 cuts the felt, the second feeding cylinder 425 and the feeding head 427 reset, and the feeding block 417 conveys the cut felt, thus completing one feeding cycle.

[0080] Please refer to Figure 15The felt feeding block 417 has felt feeding protrusions 431 on both sides near the third mounting plate 402. The felt feeding protrusions 431 and the felt extrusion forming block 412 located on the same side are in the same vertical plane. The felt extrusion forming block 412 has a felt groove 433 adapted to the felt feeding protrusion 431 on the side near the felt feeding protrusion 431. The end of the felt feeding protrusion 431 has a felt feeding groove 432. The felt extrusion forming block 412 has a felt forming protrusion 434 adapted to the felt feeding groove 432 on the inside of the felt feeding groove 433. The inside of the felt forming protrusion 434 has a felt forming groove 435. The felt forming groove 435 is collinear with the central axis of the needle hole. Specifically, the felt cut by the felt cutting blade 421 is located inside the felt feeding groove 432. When the first felt feeding cylinder 416 is started, it drives the felt feeding block 417 and the felt feeding groove. The felt inside 432 moves together, causing the felt in the feeding groove 432 at the end of the feeding protrusion 431 to be inserted into the feeding groove 433 of the feeding extrusion forming block 412. At the same time, the feeding groove 432 is sleeved on the outside of the fabric forming protrusion 434. Then the feeding block 417 continues to move towards the feeding extrusion forming block 412. The upper and lower ends of the fabric forming protrusion 434 press the felt inside the feeding groove 432, compressing it to the inside of the fabric forming groove 435 and the feeding groove 432, thereby increasing the thickness of the felt during the feeding process. Then the feeding cylinder 408 is activated, and the felt inside the fabric forming groove 435 and the feeding groove 432 is inserted into the inside of the linkage rod through the feeding connecting rod 409 and the needle 410, completing the perforation of the felt. Then the conveying module 300 transports the fed linkage rod to the dispensing module 500.

[0081] Please refer to Figure 16-18 The dispensing and cutting assembly includes a fifth mounting frame 506 fixed on the top of the workbench 100 and located at the end of the second mounting plate 401 away from the vibrating feeding tray 201 of the linkage rod. The top of the fifth mounting frame 506 is fixed with a first feeding track 507 and a second feeding track 508. The ends of the first feeding track 507 and the second feeding track 508 away from the second mounting plate 401 are set as inclined table surfaces. The end of the second feeding track 508 near the second mounting plate 401 is provided with a feeding tab 1 509 and a feeding tab 2 512.

[0082] A fourth mounting bracket 504 is provided on the side of the first feeding track 507 away from the second feeding track 508. The fourth mounting bracket 504 is fixedly connected to the worktable 100. A lifting cylinder 514 is installed at the bottom of the fourth mounting bracket 504 near the first feeding track 507. A lifting frame 513 is fixedly connected to the output end of the lifting cylinder 514. Several support rods are provided on the top of the lifting frame 513. The support rods are distributed between the first feeding track 507 and the second feeding track 508 and on the side of the second feeding protrusion 512 away from the first feeding protrusion 509. A paddle drive cylinder 511 is installed on the top of the worktable 100 and below the second feeding track 508. A transport paddle 510 is fixed to the output end of the paddle drive cylinder 511. The transport paddle 510 is located on the outside of the first feeding protrusion 509 and the first feeding track 507.

[0083] A fan 505 is provided on the top of the fourth mounting bracket 504, and the fan 505 is located above the landing gear 513;

[0084] The dispensing assembly includes a third mounting bracket 501 fixed to the top of the workbench 100 and located on both sides of the fourth mounting bracket 504. A dispensing delivery cylinder 502 is mounted on the top of the third mounting bracket 501, and a dispensing head 503 is mounted on the top of the output end of the dispensing delivery cylinder 502.

[0085] After the linkage rod is threaded through the felt, the first transmission belt 305, through the conveying assembly and the material handling assembly, places the linkage rod on top of the landing gear 513 at the end of the first unloading track 507 and the second unloading track 508, near the fourth mounting bracket 504. Then, the lifting cylinder 514 is activated, moving the landing gear 513 upwards to the appropriate position. Subsequently, the glue dispensing cylinders 502 on both sides of the landing gear 513 are activated, moving the glue dispensing head 503 towards the landing gear 513 and dispensing glue onto the threaded part of the linkage rod. Simultaneously, the fan 505 remains on. After glue dispensing... It can quickly dry the glued area, thereby improving the glued effect; then the lifting cylinder 514 is activated, which drives the landing gear 513 and the linkage rod after glued on the top of the landing gear 513 to descend, so that the linkage rod is placed on the top of the first unloading track 507 and the second unloading track 508. Then the paddle drive cylinder 511 is activated, which drives the transport paddle 510 to move a short distance closer to the conveying module 600, and pushes the linkage rod after glued on the landing gear 513 forward a distance, pushing it out of the glued area. Through the continuous pushing effect, the linkage rod behind pushes the linkage rod in front to move forward.

[0086] It should be noted that the dispensing delivery cylinder 502 is mounted on the top of the third mounting bracket 501 in a rotatable and adjustable manner to accommodate different dispensing needs.

[0087] Please refer to Figure 19 The conveying module 600 includes a sixth mounting frame 601 fixed on the workbench 100 and located at the end of the second unloading track 508 away from the fourth mounting frame 504. Conveying rollers are rotatably connected to both ends of the inner top of the sixth mounting frame 601, and conveyor belts 602 are connected to the outer sides of the conveying rollers at both ends. A conveyor drive motor 603 is mounted on the workbench 100 and below the sixth mounting frame 601. A second transmission pulley 604 is fixed to the output end of the conveyor drive motor 603 and one of the conveying rollers. Second transmission belts 604 are connected to the outer sides of the two second transmission pulleys 604. A collection box 606 is provided at the end of the belt 605 and the sixth mounting bracket 601 away from the second feeding track 508 and located below the conveyor belt 602. After the dispensing is completed, the linkage rod falls through the inclined platform of the first feeding track 507 and the second feeding track 508 and lands on the top of the conveyor belt 602. At the same time, the conveyor drive motor 603 starts and drives the conveyor belt 602 to move through the second transmission pulley 604 and the second transmission belt 605, thereby transporting the linkage rod on the top of the conveyor belt 602 and collecting the linkage rod in a unified manner through the collection box 606.

[0088] The process of using the felt perforation device provided by this invention is as follows:

[0089] When using this equipment, the piano linkage rod is first fed onto the vibrating feeding plate 201 via the linkage rod vibration feeding plate. Then, the conveying module 300 picks up and places the linkage rod and moves it. The process is as follows: the conveying lifting cylinder 308 near the vibrating feeding plate 201 is activated, causing the corresponding picking and placing cylinder 309 to descend, so that it is at the same height as the linkage rod at the output end of the vibrating feeding plate 201. At this time, the picking fingers are positioned above and below the linkage rod. Then, the conveying drive motor 303 is activated, driving the conveying mounting slider 306 to move via the first transmission belt 305 and the first pulley 304. This, in turn, causes the first mounting plate 307 to move, causing it to move closer to the vibrating feeding plate 201. 1. The transport lifting cylinder 308 at one end moves to the output end of the linkage rod vibration loading plate 201 and causes the corresponding picking finger to be inserted into the inside of the picking slot 205. Then, at the same time, the first pressing cylinder 207 starts and drives the first pressing plate 208 and the first pressing head 209 to descend and press the linkage rod of the rear loading. Then, the picking and unloading cylinder 309 starts and causes the picking finger to clamp the linkage rod located at the end of the linkage rod vibration loading plate 201. Then, the cutting cylinder 203 starts and drives the cutting plate 204 to descend. Then, the transport drive motor 303 starts again and drives the linkage rod clamped by the picking finger to move to the top of the perforation and unloading fixture 405. Then, the transport lifting cylinder 308 and the picking and unloading cylinder 309 start and place the linkage rod on the top of the perforation and unloading fixture 405.

[0090] Then, the second pressing cylinder 413 is activated, driving the second pressing head 414 downwards, pressing the connecting rod and the perforating and feeding fixture 405 into the bottom of the second threading vertical plate 404. Then, the third feeding cylinder 426 is activated, driving the feeding head 427 to move and press against the fabric inside the fabric bending block 424. Then, the second feeding cylinder 425 is activated, driving the third feeding cylinder 426 and the feeding head 427 towards the feeding block 417, feeding the fabric into the feeding groove 432 inside the feeding rib 431. Then, the cutting cylinder 420 is activated, driving the cutting blade 421 downwards to cut the fabric on both sides. The cut fabric is located inside the feeding groove 432. Then, the... When the feeding cylinder 416 is activated, it drives the feeding block 417 and the fabric inside the feeding groove 432 to move towards the piercing and feeding fixture 405 simultaneously. This causes the feeding block 417 to insert into the inside of the fabric extrusion forming block 412, and the fabric forming protrusion 434 to insert into the inside of the feeding groove 432. The fabric forming protrusion 434 compresses the fabric inside the feeding groove 432, making it compressed inside the fabric forming groove 435 and the feeding groove 432. Then, the threading cylinder 408 is activated, driving the threading connecting rod 409 and the threading needle 410 to move towards the piercing and feeding fixture 405. The threading needle 410 then inserts the compressed fabric inside the fabric forming groove 435 and the feeding groove 432 into the inside of the linkage rod to complete the threading process.

[0091] After the weaving is completed, the weaving cylinder 408 and the second pressing cylinder 413 reset, the second pressing head 414 moves away from the linkage rod, and the linkage rod rises to the top of the second weaving vertical plate 404 under the action of the reset spring 407. Then, the transport lifting cylinder 308 at the end away from the vibrating feeding tray 201 of the linkage rod starts and drives the corresponding picking and unloading cylinder 309 to descend. At the same time, the corresponding picking and unloading cylinder 309 starts to clamp the weaving linkage rod and raise it to the appropriate position through the transport lifting cylinder 308. Then, the transport drive motor 303 starts to drive the clamped linkage rod to move above the landing gear 513. Then, the corresponding transport lifting cylinder 308 and picking and unloading cylinder 309 start to place the linkage rod on the top of the landing gear 513. After that, the lifting and lowering cylinder 514 starts to drive the landing gear 513 to move upward to the appropriate position. Then, the glue dispensing conveying cylinders 5 on both sides of the landing gear 513... 02. The dispensing head 503 is moved towards the landing gear 513 and dispensing glue to the threaded position of the linkage rod through the dispensing head 503. At the same time, the fan 505 is always on, which can quickly dry the glued area after dispensing, thereby improving the dispensing effect. Then, the lifting cylinder 514 is activated to lower the landing gear 513 and the linkage rod after the glue is applied to the top of the landing gear 513, so that the linkage rod is placed on the top of the first unloading track 507 and the second unloading track 508. Then, the paddle drive cylinder 511 is activated, which drives the transport paddle 510 to move a short distance towards the conveying module 600, and pushes the linkage rod after the glue is applied to the landing gear 513 forward a distance, pushing it out of the glued area. Through the continuous pushing effect, the linkage rod behind pushes the linkage rod in front to move forward to complete the glued work.

[0092] After the dispensing is completed, the linkage rod falls through the inclined platform of the first feeding track 507 and the second feeding track 508 and lands on the top of the conveyor belt 602. At the same time, the conveyor drive motor 603 starts and drives the conveyor belt 602 to move through the second transmission pulley 604 and the second transmission belt 605, thereby transporting the linkage rod on the top of the conveyor belt 602 and collecting the linkage rod in a unified manner through the collection box 606.
