Description

Technical Field

[0001] The present invention relates to the technical field of wind chime processing equipment, in particular to an assembly machine for installing a retaining spring in a wind chime tube. Background Art

[0002] Wind chimes are objects that make sounds when the wind blows, and are often used as ornaments. The sound is produced by the collision of individual bells or other objects when the wind blows.

[0003] A wind chime is generally composed of several wind chime tubes suspended on a connector by a hanging rope. The surface of the wind chime tubes currently on the market is generally drilled with holes to insert pins for tying hanging ropes, or plastic air eyes are directly installed at the holes, and the hanging ropes are connected to the plastic air eyes. However, drilling holes will leave marks on the outer wall of the wind chime tube, destroying the overall appearance of the outer wall of the wind chime tube and affecting the aesthetics. Moreover, after drilling the holes, the edges of the holes need to be polished, which is time-consuming and labor-intensive. In a wind chime in the form of a pin, the hanging rope will be displaced on the pin, which will affect the tone of the wind chime, and the pin is easy to fall off during the shaking of the wind chime, posing a safety hazard. To solve the above problems, China's authorized patent number CN202120002567.8 discloses a new type of wind chime. In this technical solution, a retaining spring is matched and connected to the mounting groove on the inner wall of the wind chime tube. However, in the prior art, the steps of digging the mounting groove and installing the retaining spring in the wind chime tube corresponding to the mounting groove position need to be performed manually, and there are the following technical defects:

[0004] 1. Manual processing and assembly efficiency is extremely low, and labor costs are high;

[0005] 2. The size of the installation groove cannot meet the clamping standard of the standard circlip, which will cause the circlip to be not firmly connected;

[0006] 3. The retaining spring is elastic and has sharp edges. When the retaining spring is connected to the mounting slot, it is necessary to make the retaining spring elastically shrink. Whether it is done manually or with external equipment, there are certain safety hazards and it is easy to damage the structure of the retaining spring, resulting in the retaining spring being unable to connect well with the hanging rope or be matched and connected in the mounting slot. Summary of the Invention

[0007] In order to solve the above problems, the present invention proposes an assembly machine for installing a retaining spring in a wind chime tube.

[0008] The technical solution adopted by the present invention is: an assembly machine for installing a retaining spring in a wind chime tube, which is used to dig an inner groove in the wind chime tube and install the retaining spring in the inner groove;

[0009] The assembly machine includes a frame and a loading mechanism, a conveying mechanism, an inner groove digging mechanism, a spring mechanism and a discharging mechanism installed on the frame;

[0010] The feeding mechanism is installed at the initial end of the frame and is used for storing and feeding the wind chime tubes;

[0011] The conveying mechanism is used to receive the wind chime tube output from the feeding mechanism and convey the wind chime tube to the discharging mechanism. During the conveying process of the wind chime tube, it will pass through the inner groove digging mechanism and the spring loading mechanism in sequence;

[0012] The inner trench digging mechanism comprises:

[0013] The groove knife control pushing device is used to control the groove knife to extend into the wind chime tube and drive the groove knife to move back and forth along the radial direction of the wind chime tube so that the groove knife contacts and leaves the inner wall of the wind chime tube;

[0014] The car slot positioning device is used to locate the position of the wind chime tube;

[0015] A three-jaw chuck is used to drive the wind chime tube to rotate radially;

[0016] During the rotation of the wind chime tube, the groove cutter digs an inner groove in the inner wall of the wind chime tube;

[0017] The spring loading mechanism comprises:

[0018] Vibrating plate, used for storing and outputting circlips;

[0019] The circlip cylinder assembly comprises a circlip cylinder and a driving cylinder connected to each other, wherein a clamping structure is provided inside the circlip cylinder;

[0020] The clamping spring grabbing and pushing device is used to grab the clamping spring and push the clamping spring to one end of the clamping spring tube through the strong shrink sleeve. At this time, the clamping spring is radially compressed and clamped in the clamping structure;

[0021] The flip auxiliary device is used to flip the retaining spring barrel with the retaining spring inside to be coaxial with the wind chime tube; the driving device is used to transport the end of the retaining spring barrel installed with the retaining spring into the interior of the wind chime tube, at which time the retaining spring barrel and the inner wall of the wind chime tube do not contact each other, and the driving cylinder synchronously drives the retaining spring located in the retaining spring barrel to pop out, and the retaining spring recovers its deformation and is installed in the inner groove;

[0022] The discharging mechanism is used to output the wind chime tube with the assembled retaining spring.

[0023] It should be noted that the feeding mechanism, conveying mechanism, inner groove digging mechanism, spring loading mechanism and discharging mechanism involved in the present invention are all controlled by PLC, realizing fully automated wind chime tube transportation, inner groove digging and retaining spring installation, with a very high degree of automation.

[0024] Preferably, the feeding mechanism includes a bell tube unloading rack, a feeding device, a material dividing device and a tube moving auxiliary device;

[0025] The wind chime tube material rack is used to store wind chime tubes;

[0026] The feeding device includes a mounting frame, a plurality of movable push rods mounted on the mounting frame, which are staggered in the longitudinal direction and arranged side by side in the transverse direction, a first cylinder that drives all the movable push rods to move up and down synchronously, and an obliquely arranged guide plate for the wind chime tube to slide down.

[0027] The material distribution device is used to receive the wind chime tubes sent from the feeding device and output the wind chime tubes to the location of the tube moving auxiliary device at intervals;

[0028] The tube moving auxiliary device is used to move the wind chime tube onto the conveying mechanism.

[0029] Preferably, the mounting frame includes a fixed plate, the first cylinder is mounted on the lower end of the fixed plate, the upper end of the fixed plate is connected to a connecting plate, a plurality of movable top plates are fixedly provided on the upper end of the connecting plate, a plurality of movable top rods are all mounted above the movable top plates, and partitions are provided between the movable top rods, the upper end surfaces of the partitions and the movable top rods are both inclined and smoothly transition to each other, and the partitions are fixedly mounted on the mounting frame.

[0030] The first cylinder is fixed by a fixed plate and is used to drive the connecting plate to move up and down. When the connecting plate moves upward, it will drive the movable top plate to move upward, and then drive the movable top rod to move upward. Since the upper end surfaces of the partition and the movable top rod are inclined, the wind chime tube entering the upper end surface of the partition will roll to the upper end surface of the movable top rod. The partition serves as a limit, and when the movable top rod moves upward to connect to the upper end surface of the next partition, the wind chime tube will continue to move and roll to the upper end surface of the next partition, and so on. Eventually, the wind chime tube will be gradually transported close to the material distribution device.

[0031] Preferably, the material dividing device includes a material dividing plate, a pushing block and a second cylinder. The upper end of the material dividing plate is provided with a first material dividing slot and a second material dividing slot. The first material dividing slot and the second material dividing slot are both limited by a limiting block. The wind chime tube will be first clamped in the first material dividing slot after being guided by the guide plate. The second cylinder drives the pushing block to move upward, and then pushes the wind chime tube up. At this time, the wind chime tube will pass over the first material dividing slot and enter the second material dividing slot. When the wind chime tube enters the second material dividing slot, the tube moving auxiliary device will take away the wind chime tube here.

[0032] Preferably, the tube transfer assist device includes a guide rail mounting plate, a third cylinder, and a tube clamping assembly. The guide rail mounting plate is provided with an obliquely arranged guide rail. The tube clamping assembly includes a support frame, a fourth cylinder mounted above the support frame, and at least one fifth cylinder mounted in the support frame. The fifth cylinder has a clamping claw at its lower end, which is used to drive the clamping claw, while the fourth cylinder drives the support frame to move up and down. The third cylinder is mounted on the guide rail mounting plate and connected to the support frame, with one side of the support frame slidingly connected to the guide rail. The third cylinder drives the support frame to move on the guide rail, ultimately transporting the wind chime tube clamped by the clamping claw to the conveying mechanism.

[0033] It should be noted that the above-mentioned dividing plate and guide rail mounting plate and the corresponding structures are all installed symmetrically front to back to ensure that the wind chime tube can be smoothly displaced and transported.

[0034] Here, a discharge sensor is generally installed between the tube transfer auxiliary device and the conveying mechanism. When the discharge sensor does not detect that there is a wind chime tube placed on the conveying mechanism, it will automatically alarm. Generally, there is a problem in one of the processes of the loading mechanism, and the machine fault can be checked in time.

[0035] Preferably, the conveying mechanism includes at least two sprocket assemblies arranged along the conveying direction of the wind chime tube and running synchronously, a third motor for driving the sprocket assembly, and pipe seats evenly spaced apart on the chain of the sprocket assembly. The pipe seats located on different sprocket assemblies correspond to each other one by one along the axial direction of the wind chime tube, and are used together to support and place the wind chime tube.

[0036] Generally, the sprocket assembly includes a driving sprocket and multiple driven sprockets, wherein the driving sprocket is connected to a third motor, and the driving sprocket and the driven sprocket are connected by a transmission rod. The chain is generally provided with two groups, which are symmetrical with each other front and back. All sprockets on the chain except the above-mentioned driving sprocket are driven sprockets. When one of the driving sprockets is driven to rotate by the third motor, the transmission rod will drive the rotation of its corresponding driven sprocket. The driven sprocket on the same chain as the driving sprocket will also rotate, which will drive both chains to rotate. The rotation of the two chains is synchronous, and the pipe holders installed on the two chains will also be driven synchronously to ensure the smooth and directional transportation of the wind chime tube.

[0037] Preferably, the slotting cutter control and pushing device includes a first linear motor module, a second linear motor module, and a slotting cutter assembly. The slotting cutter assembly includes a base and an extension rod mounted on the base. The slotting cutter is mounted on one end of the extension rod. The second linear motor module is mounted on the first linear motor module. The base is mounted on the second linear motor module. When the slotting positioning device has positioned the wind chime tube, the extension rod and the wind chime tube are coaxial. The first linear motor module drives the extension rod and the slotting cutter to extend along the length of the wind chime tube into the interior of the wind chime tube by driving the linear motion of the second motor module. The second linear motor module is used to drive the slotting cutter to move back and forth linearly along the radial direction of the wind chime tube. The motor mounted on the first linear motor module is the first motor, and the motor mounted on the second linear motor module is the second motor.

[0038] Preferably, the vehicle slot positioning device includes a proximity sensor, an upper positioning groove wheel and a lower positioning groove wheel arranged in an upper and lower position, and a sixth cylinder for driving the lower positioning groove wheel to move up and down. There are two lower positioning groove wheels and they are arranged relatively spaced apart. When the proximity sensor detects that the wind chime tube reaches a predetermined position, the sixth cylinder drives the two lower positioning groove wheels to rise. At this time, the upper positioning groove wheel and the two lower positioning groove wheels jointly clamp the wind chime tube, and one of the free ends of the wind chime tube is clamped through the clamping port of the three-jaw chuck.

[0039] Here, when the proximity sensor senses that the wind chime tube has reached a predetermined position, the sixth cylinder drives the lower positioning groove wheel upward, and the wind chime tube is precisely clamped between the two lower positioning groove wheels until the upper positioning groove wheel and the two lower positioning groove wheels jointly clamp the wind chime tube. At this time, one free end of the wind chime tube is clamped by the clamping opening of the three-jaw chuck. The design of the groove positioning device ensures that the clamping opening and the wind chime tube are coaxially positioned. It also ensures that when the extension rod enters the wind chime tube, the extension rod and the wind chime tube are coaxial. Ensure that after the wind chime tube is driven to rotate by the three-jaw chuck, the groove cutter can evenly and smoothly cut the inner groove along the radial direction in the inner wall of the wind chime tube.

[0040] Preferably, the upper spring mechanism also includes a direct vibration conveying device, which is located between the vibration disk and the retaining spring grabbing and pushing device, and includes a bracket and a direct vibrator installed on the bracket. The upper end of the direct vibrator is provided with a conveying plate, and the conveying plate is provided with a first conveying trough for conveying the retaining spring, and the conveying plate is connected to the discharge end of the vibration disk.

[0041] Preferably, the retaining spring grabbing and pushing device includes an upper support plate, a seventh cylinder installed above the upper support plate, a sleeve connected to the seventh cylinder, and an eighth cylinder installed above the sleeve, the upper support plate is provided with a first through hole, a second through hole and a second conveying trough, the second conveying trough is connected to the first conveying trough, and the first through hole is installed in the second conveying trough at an end away from the first conveying trough; a ninth cylinder is provided on the upper support plate and corresponding to the position of the first through hole, the ninth cylinder is used to push the retaining spring delivered to the upper end of the first through hole, a grabbing sleeve is provided in the sleeve, the seventh cylinder is used to drive the sleeve seat to move above the first through hole, at this time the eighth cylinder drives the grabbing sleeve to grab the retaining spring, the seventh cylinder drives the sleeve seat to reset and make the grabbing sleeve correspond to the top of the second through hole, the strong shrinkage sleeve is provided in the second through hole, at this time the eighth cylinder drives the retaining spring in the grabbing sleeve to be compressed by the strong shrinkage sleeve and pushed to one end of the retaining spring tube.

[0042] Through the above technical solution, the vibrating disk outputs the retaining spring to the first conveying slot of the conveying plate, and the straight vibrator drives the retaining spring to be conveyed to the second conveying slot of the upper support plate. Finally, the retaining spring will enter the position of the first through hole. At this time, the ninth cylinder drives the ejecting block to push up and slightly push out the retaining spring, which is convenient for the subsequent grabbing sleeve to grab. The seventh cylinder drives the sleeve seat to move above the first through hole, and the eighth cylinder drives the grabbing sleeve in the displacement sleeve to press down and grab the retaining spring. A pressure block will be provided in the grabbing sleeve. After grabbing the retaining spring, the seventh cylinder drives the sleeve seat to reset to the top of the second through hole. At this time, the eighth cylinder drives the pressure block to press the retaining spring in the grabbing sleeve down into the strong shrinkage sleeve, and realizes the elastic shrinkage of the retaining spring through the strong shrinkage sleeve. Finally, the retaining spring will be pressed into the retaining spring tube.

[0043] Preferably, the driving cylinder is the tenth cylinder, the clamping structure is a fixed needle groove provided inside the retaining spring tube along the length direction, and the tenth cylinder is provided at one end of the retaining spring tube away from the retaining spring.

[0044] Preferably, the flipping auxiliary device includes a vertical plate, an adapter seat, a connecting seat, a rotating member and a cylinder pushing module. The vertical plate is provided with an obliquely arranged guide rail, the retaining spring tube assembly is connected to the rotating member, one end of the rotating member is provided with a roller, the roller rolls and slides in the guide rail, the rotating member is installed on the connecting seat through a bearing, the connecting seat is slidably installed above the cylinder pushing module, the vertical plate is fixedly installed on the cylinder pushing module, the cylinder pushing module is used to drive the connecting seat for linear displacement, at this time the retaining spring tube is synchronously flipped by the rotation of the rotating member until it is coaxial with the wind chime tube, the driving device is a third linear motor module, the cylinder pushing module is installed on the third linear motor module, and the third linear motor module is used to drive the cylinder pushing module for linear displacement.

[0045] Through the above technical solution design, the cylinder installed on the cylinder pushing module is the eleventh cylinder. When the retaining ring is clamped on one end of the fixed needle groove of the retaining ring tube, the cylinder pushing module drives the connecting seat to perform linear displacement. The linear displacement of the connecting seat will drive the rotating part and the adapter seat connected thereto to move synchronously. Since the roller on the rotating part moves on the guide track arranged in an oblique direction, the relative height of the bearing and the roller will change, and since the height of the bearing remains unchanged, the rotating part will rotate, thereby causing the retaining ring tube connected to the rotating part to rotate, and finally causing the retaining ring tube to rotate to be coaxial with the wind chime tube.

[0046] When the wind chime tube and the retaining spring barrel are coaxial, the third linear motor module located on the frame drives the cylinder pushing module to perform a linear displacement as a whole, so that the retaining spring barrel enters the wind chime tube. It should be noted that the retaining spring barrel and the inner wall of the wind chime tube do not contact each other throughout the entire process. When the retaining spring on the retaining spring barrel is displaced to the position of the inner groove, the tenth cylinder drives the fixed needle groove to push out the retaining spring and restore the deformation. At this time, the retaining spring will be matched and installed in the inner groove. After the above work is completed, the third linear motor module drives the cylinder pushing module to reset. Similarly, the retaining spring barrel will be flipped back to the vertical state with the assistance of the flip auxiliary device to meet the next retaining spring.

[0047] More preferably, the frame is further provided with an oil dripping device and an air-blowing chip removal device, the oil dripping device is used to drip oil into the inner groove, and the air-blowing chip removal device is used to recycle chips generated during the process of digging the inner groove.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] 1. High degree of automation, low labor cost and extremely high work efficiency;

[0050] 2. The inner groove is precisely dug and the retaining ring can be accurately placed in the inner groove. The redundant structure will not accidentally touch the inner wall of the wind chime tube, and the defective rate is low.

[0051] 3. It avoids the potential safety hazards caused by manual installation of the retaining spring, does not damage the retaining spring structure, saves time and effort, and is suitable for large-scale production and processing in modern industry. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end surfaces of the partition 226 and the movable top rod 225 are both inclined and smoothly transition to each other. The partition 226 is fixedly installed on the mounting frame 221.

[0099] The first cylinder 222 is fixed by the fixed plate 223 and is used to drive the connecting plate 227 to move up and down. When the connecting plate 227 moves upward, it will drive the movable top plate 224 to move upward, and then drive the movable top rod 225 to move upward. Since the upper end surfaces of the partition 226 and the movable top rod 225 are both inclined, the wind chime tube a entering the upper end surface of the partition 226 will roll to the upper end surface of the movable top rod 225. The partition 226 serves as a limit, and when the movable top rod 225 moves upward to connect to the upper end surface of the next partition 226, the wind chime tube a will continue to move and roll to the upper end surface of the next partition 226, and so on. Finally, the wind chime tube a will be gradually transported close to the material distribution device 230.

[0100] In addition, the material dividing device 230 includes a material dividing plate 231, a pushing block 233 and a second cylinder 232. The upper end of the material dividing plate 231 is provided with a first material dividing slot 2311 and a second material dividing slot 2312. The first material dividing slot 2311 and the second material dividing slot 2312 are both limited by a limiting block 2313. The wind chime tube a will be guided by the guide plate 228 and will first be clamped in the first material dividing slot 2311. The second cylinder 232 drives the pushing block 233 to move upward, and then push the wind chime tube a up. At this time, the wind chime tube a will pass over the first material dividing slot 2311 and enter the second material dividing slot 2312. When the wind chime tube a enters the second material dividing slot 2312, the tube moving auxiliary device 240 will take away the wind chime tube a here.

[0101] As a preferred implementation of this embodiment, the pipe moving auxiliary device 240 includes a guide rail mounting plate 242, a third cylinder 241 and a pipe clamping assembly 243. The guide rail mounting plate 242 is provided with an obliquely arranged guide rail 2421. The pipe clamping assembly 243 includes a support frame 2432. A fourth cylinder 2431 is installed above the support frame 2432. At least one fifth cylinder 2433 is installed in the support frame 2432. A clamping claw 2434 is provided at the lower end of the fifth cylinder 2433. The fifth cylinder 2433 is used to drive the clamping claw 2434 to work, and the fourth cylinder 2431 is used to drive the support frame 2432 to move up and down. The third cylinder 241 is installed on the guide rail mounting plate 242. The third cylinder 241 is connected to the support frame 2432, and one side of the support frame 2432 is slidably connected to the guide rail 2421. The third cylinder 241 drives the support frame 2432 to move on the guide rail 2421, and finally transports the wind chime tube a clamped by the clamp 2434 to the conveying mechanism 400.

[0102] It should be noted that the above-mentioned dividing plate 231 and the guide rail mounting plate 242 and the corresponding structures are all installed symmetrically in the front and back, ensuring that the wind chime tube a can be smoothly displaced and transported.

[0103] Here, a discharge sensor is generally provided between the tube moving auxiliary device 240 and the conveying mechanism 400. When the discharge sensor does not detect that there is a wind chime tube a placed on the conveying mechanism 400, it will automatically alarm. Generally, there is a problem in one of the processes of the loading mechanism 200, and the machine failure can be checked in time.

[0104] It should be noted that the discharging mechanism 600 includes a discharging pipe moving device 610, a discharging device 620 and a discharging output end 630. Here, the discharging pipe moving device 610 and the pipe moving auxiliary device 240 have basically the same structure, and the discharging device 620 and the feeding device 220 have basically the same structure, so they will not be elaborated on. They are mainly used to output the assembled wind chime tube a intact to the discharging output end 630, and then enter the next workstation.

[0105] Then, the conveying mechanism 400 includes at least two sprocket assemblies 430 arranged along the conveying direction of the wind chime tube a and running synchronously, a third motor 420 for driving the sprocket assembly 430 to work, and a pipe seat 440 evenly spaced apart and installed on the chain 434 of the sprocket assembly 430. The pipe seats 440 located on different sprocket assemblies 430 correspond to each other one by one along the axial direction of the wind chime tube a, and are jointly used to support and place the wind chime tube a.

[0106] Typically, the sprocket assembly 430 includes a driving sprocket 431 and multiple driven sprockets 433. The driving sprocket 431 is connected to the third motor 420, and the driving sprockets 431 and the driven sprockets 433 are connected via a transmission rod 432. The chains 434 are generally provided in two sets, symmetrically arranged front to back. All sprockets on the chains 434, except for the driving sprocket 431, are driven sprockets 433. When one of the driving sprockets 431 is driven to rotate by the third motor 420, the transmission rod 432 drives the corresponding driven sprocket 433 to rotate. The driven sprocket 433 on the same chain 434 as the driving sprocket 431 also rotates, thereby driving both chains 434 to rotate synchronously. Consequently, the pipe holders 440 mounted on the two chains 434 are also driven synchronously, ensuring smooth and directional transport of the wind chime pipe a.

[0107] In this embodiment, the sprocket assembly 430 is placed on a support plate 110 located above the rack 100 . A slide rail 120 is provided below the support plate 110 . The slide rail 120 is used to assist in adjusting the position of the sprocket assembly 430 .

[0108] As another preferred implementation of this embodiment, the groove cutter control pushing device 300 includes a first linear motor module 312, a second linear motor module 314 and a groove cutter assembly 315. The groove cutter assembly 315 includes a base and an extension rod 3151 installed on the base. The groove cutter 3152 is installed at one end of the extension rod 3151. The second linear motor module 314 is installed on the first linear motor module 312, and the base is installed on the second linear motor module 314. When the groove positioning device 320 completes positioning the wind chime tube a, the extension rod 3151 and the wind chime tube a are coaxial. The first linear motor module 312 drives the extension rod and the groove cutter 3152 to extend along the length of the wind chime tube a to the inside of the wind chime tube a by driving the linear motion of the second motor module 314. The second linear motor module 314 is used to drive the groove cutter 3152 to move back and forth in a radial direction of the wind chime tube a. The motor installed on the first linear motor module 312 is the first motor 311 , and the motor installed on the second linear motor module 314 is the second motor 313 .

[0109] Next, the vehicle slot positioning device 320 includes an upper positioning groove wheel 325 and a lower positioning groove wheel 323 arranged in an upper and lower position, a sixth cylinder 321 for driving the lower positioning groove wheel 323 to move up and down, and a proximity sensor 322. There are two lower positioning groove wheels 323 and they are arranged relatively spaced apart. When the proximity sensor 322 detects that the wind chime tube a reaches a predetermined position, the sixth cylinder 321 drives the two lower positioning groove wheels 323 to rise. At this time, the upper positioning groove wheel 325 and the two lower positioning groove wheels 323 jointly clamp the wind chime tube a, and one of the free ends of the wind chime tube a is clamped through the clamping port 331 of the three-jaw chuck 330.

[0110] Here, when the proximity sensor 322 senses that the wind chime tube a has reached a predetermined position, the sixth cylinder 321 drives the lower positioning groove wheel 323 upward, and the wind chime tube a is precisely clamped between the two lower positioning groove wheels 323 until the upper positioning groove wheel 325 and the two lower positioning groove wheels 323 jointly clamp the wind chime tube a. At this time, one free end of the wind chime tube a is clamped by the clamping opening 331 of the three-jaw chuck 330. The design of the groove positioning device 320 ensures that the clamping opening 331 and the wind chime tube a are coaxially positioned. It also ensures that when the extension rod 3151 subsequently enters the wind chime tube a, the extension rod 3151 and the wind chime tube a are coaxial, ensuring that after the wind chime tube a is driven to rotate by the three-jaw chuck 330, the groove cutter 3152 can evenly and smoothly cut the inner groove a1 in the inner wall of the wind chime tube a in the radial direction.

[0111] In this embodiment, the upper spring mechanism 500 also includes a direct vibration conveying device 520, which is located between the vibration disk 510 and the spring grabbing and pushing device 530, and includes a bracket 523 and a direct vibrator 521 installed on the bracket 523. The upper end of the direct vibrator 521 is provided with a conveying plate 522, and the conveying plate 522 is provided with a first conveying groove 5221 for conveying the spring b. The conveying plate 522 is connected to the discharge end of the vibration disk 510.

[0112] Then, the spring grabbing and pushing device 530 includes an upper supporting plate 531, a seventh cylinder 532 installed above the upper supporting plate 531, a sleeve 536 connected to the seventh cylinder 532, and an eighth cylinder 533 installed above the sleeve 536. The upper supporting plate 531 is provided with a first through hole 5312, a second through hole 5313 and a second conveying groove 5311. The second conveying groove 5311 is connected to the first conveying groove 5221. The first through hole 5312 is installed at an end of the second conveying groove 5311 away from the first conveying groove 5221. A ninth cylinder 533 is provided on the upper supporting plate 531 and corresponds to the position of the first through hole 5312. 4. The ninth cylinder 534 is used to push up the retaining spring b delivered to the upper end of the first through hole 5312. A grabbing sleeve 535 is provided in the sleeve 536. The seventh cylinder 532 is used to drive the sleeve 536 to move to the top of the first through hole 5312. At this time, the eighth cylinder 533 drives the grabbing sleeve 535 to grab the retaining spring b. The seventh cylinder 532 drives the sleeve 536 to reset and make the grabbing sleeve 535 correspond to the top of the second through hole 5313. The strong shrinkage sleeve 538 is provided in the second through hole 5313. At this time, the eighth cylinder 533 drives the retaining spring b located in the grabbing sleeve 535 to be compressed by the strong shrinkage sleeve 538 and then pushed to one end of the retaining spring tube 541.

[0113] In this embodiment, the vibrating plate 510 delivers the retaining spring b to the first conveying slot 5221 of the conveying plate 522. The linear vibrator 521 drives the retaining spring b to the second conveying slot 5311 of the upper support plate 531. Eventually, the retaining spring b enters the location of the first through-hole 5312. At this point, the ninth cylinder 534 drives the ejection block upward, slightly pushing out the retaining spring b, facilitating subsequent capture by the grabbing sleeve 535. The seventh cylinder 532 drives the sleeve 536 to move above the first through-hole 5312. The eighth cylinder 533 drives the grabbing sleeve 535 in the displacement sleeve 536 downward to capture the retaining spring b. A pressure block 537 will be provided in the grabbing sleeve 535. After grabbing the retaining spring b, the seventh cylinder 532 drives the sleeve seat 536 to reset to the top of the second through hole 5313. At this time, the eighth cylinder 533 drives the pressure block 537 to press the retaining spring b in the grabbing sleeve 535 down to the strong shrinkage sleeve 538, and the elastic shrinkage of the retaining spring b is realized through the strong shrinkage sleeve 538. Finally, the retaining spring b will be pressed into the retaining spring tube 541.

[0114] In this embodiment, the driving cylinder is the tenth cylinder 542, and the clamping structure is a fixed needle groove 5411 arranged inside the spring tube along the length direction. The tenth cylinder 542 is arranged at the end of the spring tube 541 away from the spring b.

[0115] The flip assist device 550 includes a vertical plate 551, an adapter seat 552, a connecting seat 553, a rotating member 554 and a cylinder pushing module 580. The vertical plate 551 is provided with an obliquely arranged guide rail 5511. The spring cylinder assembly 540 is connected to the rotating member 554. One end of the rotating member 554 is provided with a roller 5542. The roller 5542 rolls and slides in the guide rail 5511. The rotating member 554 is installed on the connecting seat 552 through a bearing 5541. The connecting seat 553 is slidably installed on the cylinder pushing module 5 80, the vertical plate 551 is fixedly mounted on the cylinder pushing module 580, and the cylinder pushing module 580 is used to drive the connecting seat 553 to perform linear displacement. At this time, the retaining spring tube 541 is synchronously flipped by the rotation of the rotating member 554 until it is coaxial with the wind chime tube a. A third linear motor module 560 (driving device) is provided on the frame 100, and the cylinder pushing module 580 is mounted on the third linear motor module 560. The third linear motor module 560 is used to drive the cylinder pushing module 580 to perform linear displacement.

[0116] In this embodiment, the cylinder installed on the cylinder pushing module 580 is the eleventh cylinder 590. When the retaining ring b is clamped on one end of the fixed needle groove 5411 of the retaining ring tube 541, the cylinder pushing module 580 drives the connecting seat 553 to perform linear displacement. The linear displacement of the connecting seat 553 will drive the rotating member 554 and the adapter seat 552 connected thereto to move synchronously. Since the roller 5542 on the rotating member 554 moves on the obliquely arranged guide track 5511, the relative height of the bearing 5541 and the roller 5542 will change, and since the height of the bearing 5541 remains unchanged, the rotating member 554 will rotate, thereby causing the retaining ring tube 541 connected to the rotating member 554 to rotate, and finally causing the retaining ring tube 541 to rotate to be coaxial with the wind chime tube a.

[0117] When the wind chime tube a and the retaining spring tube 541 are coaxial, the third linear motor module 560 located on the frame 100 drives the cylinder pushing module 580 to perform a linear displacement as a whole, so that the retaining spring tube 541 enters the wind chime tube a. It should be noted that the retaining spring tube 541 and the inner wall of the wind chime tube a do not contact each other throughout the entire process. When the retaining spring b on the retaining spring tube 541 is displaced to the position of the inner groove a1, the tenth cylinder 542 drives the fixed needle groove 5411 to push out the retaining spring b and restore the deformation. At this time, the retaining spring b will be matched and installed in the inner groove a1. After the above work is completed, the third linear motor module 560 drives the cylinder pushing module 580 to reset. Similarly, the retaining spring tube 541 will flip back to the vertical state with the assistance of the flipping auxiliary device 550 to meet the next retaining spring b.

[0118] More specifically, the frame 100 is further provided with an oil dripping device and an air blowing chip removal device. The oil dripping device is used to drip oil into the inner groove a1, and the air blowing chip removal device is used to recycle chips generated during the excavation of the inner groove a1.
