[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0055] like Figure 1 As shown, the present invention includes a conveyor line 1, and a spray rail mechanism 2, a nozzle mechanism 3, a coil mechanism 4 and a snap ring mechanism 5 are sequentially arranged in the conveying direction of the conveyor line 1.

[0056] The spray rail mechanism 2 includes a first working platform 21, on which are mounted a first material tray 22, a rotating assembly 24, a first transfer assembly 23, an air inlet moving assembly 25, and a plug moving assembly 26. Spray rail bodies 81 to be assembled are arranged inside the first material tray 22. The first transfer assembly 23 includes a first slide rail 231 fixed to the first working platform 21, and a first slider 232 adapted to the first slide rail 231. A first ball screw pair 234, co-oriented with the first slide rail 231, is located near the first slide rail 231. The first slider 232 is fixed to a nut on the first ball screw pair 234. The ball screw is connected to a first driving member 233, which drives the ball screw to rotate in both directions, causing the first slider 232 to reciprocate along the first slide rail 231. The first slider 232 is provided with a second slide rail 235, and a second slider 236 is adapted on the second slide rail 235. The second slider 236 is connected to a second driving member 237. The second driving member 237 drives the second slider 236 to reciprocate along the second slide rail 235, realizing the reciprocating translation of the second slider 236 along the X-axis. The second slider 236 is provided with a third slide rail 238, and a third slider 239 is adapted on the third slide rail 238. The third slider 239 is connected to a third driving member 2310. The third driving member 2310 drives the third slider 239 to reciprocate along the third slide rail 238. The third slider 239 is provided with a first gripper 2312. The two grippers of the first gripper 2312 move relative to each other under the drive of the driving member to grip the spray rail body 81.

[0057] like Figure 2As shown, the rotating assembly 24 includes a bracket 241 fixed to the first working platform 21. A fourth slide rail 242 is provided on the top of the bracket 241. The fourth slide rail 242 is adapted to a first mounting plate 243. The first mounting plate 243 is connected to a fourth driving member 244. The fourth driving member 244 drives the first mounting plate 243 to reciprocate along the fourth slide rail 242. A fifth driving member 245 is provided on the first mounting plate 243. A second mounting plate 246 is provided at the output end of the fifth driving member 245. The fifth driving member 245 drives the second mounting plate 246 to move up and down along the first mounting plate 243. The second mounting plate 246 has three clamping parts arranged sequentially along the moving direction of the first mounting plate 243: a first clamping part 247, a second clamping part 248, and a third clamping part 249. Each clamping part includes two jaws. The two jaws move relative to each other under the drive of the corresponding driving member to clamp the spray rail body 81. The second clamping part 247... A rotatable rotating block 2410 is provided between the driving component and the second mounting plate 246. One end of the rotating block 2410 is connected to the second mounting plate 246, and the other end is connected to the second clamping part 248. A driving component is provided for the rotating block 2410. The driving component drives the rotating block 2410 to rotate, thereby driving the second clamping part 248 to rotate. This allows the second clamping part 248 to clamp and rotate at the same time, so as to change the horizontal placement angle of the spray rail body 81. Three sliding bases 2411 are provided below the first clamping part 247, the second clamping part 248, and the third clamping part 249. Each sliding base 2411 is provided with a guide rail 12. Two first clamping blocks 2412 are adapted on the guide rail 12. One of the clamping blocks is connected to the driving component. The driving component drives the first clamping block 2412 to move back and forth toward the other first clamping block 2412, so that the two first clamping blocks 2412 move back and forth relative to each other to clamp the spray rail body 81.

[0058] It should be noted that when the first clamping block 2412 clamps the spray rail body 81, a certain distance is left between the two first clamping blocks 2412 to avoid the clamping claws of the clamping part, so that the two clamping claws of the clamping part will not interfere with the clamping claws when clamping the spray rail body 81.

[0059] The first transfer component 23 picks up the spray rail body 81 from the first tray 22 and transfers it to the first sliding base 2411. The spray rail body 81 on the sliding base 2411 is fixed by the first clamping block 2412. The first clamping part 247 clamps the spray rail body 81 onto the sliding base 2411 corresponding to the second clamping part 248. The second clamping part 248 picks up the spray rail body 81 on the sliding base 2411 and rotates it horizontally by 90 degrees to adjust the spray rail body 81 to the optimal assembly position. Then, the third clamping part 249 picks up the spray rail body 81 onto the third sliding base 2411 and fixes it.

[0060] The air intake port moving assembly 25 and the plug moving assembly 26 are located on both sides of the third sliding base 2411, so as to install the air intake port 82 and the plug 83 at both ends of the spray rail body 81, as follows. Figure 3 As shown, the air intake interface moving assembly 25 includes a first base 251 fixed to the first working platform 21, a fifth slide rail 252 provided on the first base 251, a fourth slider 253 slidably connected on the fifth slide rail 252, a driving member provided on the fourth slider 253, and the output end of the driving member connected to the first sleeve 255.

[0061] A driving component is provided on the first base 251. A third mounting plate 257 is provided at the output end of the driving component. The driving component drives the third mounting plate 257 to perform lifting and lowering movements. A sixth driving component 258 is provided on the third mounting plate 257. A first positioning block 254 is provided at the output end of the sixth driving component 258. The sixth driving component 258 drives the first positioning block 254 to reciprocate toward the end of the spray rail body 81. A positioning groove 57 is opened in the first positioning block 254. An entrance communicating with the positioning groove 57 is opened at the top of the first positioning block 254. A guide channel is connected to the entrance of the first positioning block 254. A vibratory feeder is connected to the other end of the guide channel. The air inlet 82 in the vibratory feeder falls into the air through the guide channel. The first positioning block 254 is positioned in the positioning groove 57, which positions and fixes the air inlet 82. At this time, one end of the air inlet 82 is exposed outside the first positioning block 254. The first positioning block 254 moves under the drive of the sixth driving member 258 and approaches the end of the spray rail body 81. Then, the first sleeve 255 moves with the fourth slider 253 and is sleeved on the exposed end of the air inlet 82, pushing the air inlet 82 along the positioning groove 57 toward the end of the spray rail body 81 until the other end of the air inlet 82 is inserted into the through hole at the end of the spray rail body 81. Finally, the first sleeve 255 rotates under the drive of the driving member, thereby screwing the air inlet 82 onto the spray rail body 81.

[0062] like Figure 4 As shown, the plug moving assembly 26 includes a second base 261 fixed to the first working platform 21, a sixth slide rail 262 on the second base 261, a fifth slider 263 slidably connected on the sixth slide rail 262, a driving member on the fifth slider 263, and a second sleeve 265 connected to the output end of the driving member.

[0063] The second base 261 is equipped with a seventh driving component 266. The output end of the seventh driving component 266 is equipped with a fourth mounting plate 267. The seventh driving component 266 drives the fourth mounting plate 267 to perform lifting and lowering movements. The fourth mounting plate 267 is equipped with an eighth driving component 268. The output end of the eighth driving component 268 is equipped with a second positioning block 264. The eighth driving component 268 drives the second positioning block 264 to reciprocate toward the other end of the spray rail body 81. A positioning groove 57 is opened inside the second positioning block 264. An entrance communicating with the positioning groove 57 is opened at the top of the second positioning block 264. A guide channel is connected to the entrance of the second positioning block 264, and a vibrating plate is connected to the other end of the guide channel. The plug 83 falls into the positioning groove 57 of the second positioning block 264 through the guide channel. The positioning groove 57 positions and fixes the plug 83. At this time, one end of the plug 83 is exposed outside the second positioning block 264. The second positioning block 264 moves and approaches the end of the spray rail body 81 under the drive of the seventh driving member 266. Then, the second sleeve 265 moves with the fifth slider 263 and is sleeved on the exposed end of the plug 83, pushing the plug 83 along the positioning groove 57 toward the end of the spray rail body 81 until the other end of the plug 83 is inserted into the through hole at the end of the spray rail body 81. Finally, the second sleeve 265 rotates under the drive of the driving member, thereby screwing the plug 83 onto the spray rail body 81.

[0064] like Figure 5 and 6 As shown, the nozzle mechanism 3 includes a second working platform 31, on which a turntable 311 is provided. The turntable 311 is provided with a plurality of positioning seats 312 arranged in a ring. The positioning seats 312 are provided with positioning holes for positioning valve stem 86 and valve core 84.

[0065] The valve core moving assembly 34 includes a third base 341 fixed to the second working platform 31. A positioning groove 57 is formed on the third base 341. A sixth slider 342 is slidably connected to the third base 341. A driving component is connected to the sixth slider 342, driving it to reciprocate along the positioning groove 57. A guide channel is connected to the top of the positioning groove 57, and the other end of the guide channel is connected to a vibrating plate. The valve core 84 inside the vibrating plate falls directly into the positioning groove 57 through the guide channel. After the valve core 84 falls into the positioning groove 57, the sixth slider 342 pushes the valve core 84 a certain distance to avoid the guide channel. The valve core 84 is located near the second working platform 31. The third base 341 is provided with a first translation and lifting mechanism 32. The first translation and lifting mechanism 32 includes a base, a guide rail 12, a slider and a driving component. The guide rail 12 is located on the base, and the slider is fitted onto the guide rail 12. The driving component drives the slider to move back and forth, thereby realizing translation and lifting actions. The first translation and lifting mechanism 32 is provided with a second gripper 343. The second gripper 343 realizes translation and lifting actions through the first translation and lifting mechanism 32. The two grippers of the second gripper 343 move relative to each other under the drive of the driving component to grip the valve core 84 and grab the valve core 84 from the positioning groove 57 into the positioning hole of the positioning seat 312.

[0066] The spring moving assembly 35 includes a fourth base 351 fixed to the second working platform 31. A seventh slider 352 is slidably connected to the fourth base 351. The seventh slider 352 can move up and down along the fourth base 351 under the drive of the driving component. The seventh slider 352 is provided with a guide groove 52. One end of the guide groove 52 is connected to a guide channel, and the other end is connected to a guide sleeve. The other end of the guide channel is connected to a vibrating plate. The spring 85 in the vibrating plate falls directly into the guide groove 52 through the guide channel. The spring 85 falls directly from the top of the valve core 84 to the valve core 84 along the guide groove 52.

[0067] The valve stem moving assembly 36 includes a fifth base 361 fixed to the second working platform 31. A positioning groove 57 is formed on the fifth base 361. An eighth slider 362 is slidably connected to the fifth base 361. A driving component is connected to the eighth slider 362, driving it to reciprocate along the positioning groove 57. A guide channel is connected to the top of the positioning groove 57, and the other end of the guide channel is connected to a vibrating plate. The valve stem 86 in the vibrating plate falls directly into the positioning groove 57 through the guide channel. After the valve stem 86 falls into the positioning groove 57, the eighth slider 362 pushes the valve stem 86 a certain distance to avoid the guide channel. On the second working platform 31, near the fifth base 361, there is a second translation and lifting mechanism 364 with the valve core moving assembly 34. The second translation and lifting mechanism 364 can also perform translation and lifting actions. The second translation and lifting mechanism 364 is provided with a third gripper 363. The third gripper 363 realizes translation and lifting actions through the second translation and lifting mechanism 364. The two grippers of the third gripper 363 move relative to each other under the drive of the driving component to grip the valve stem 86, and grab the valve stem 86 from the positioning groove 57 to the positioning seat 312 which is equipped with the valve core 84 and the spring 85, so as to realize the assembly of the valve stem 86, the valve core 84 and the spring 85.

[0068] The O-ring moving assembly 37 includes a sixth base 371 fixed to the second working platform 31. The sixth base 371 has a positioning groove 57. A ninth slider 372 is slidably connected to the sixth base 371. A driving component is connected to the ninth slider 372, driving it to reciprocate along the positioning groove 57. A guide channel is connected to the top of the positioning groove 57, and the other end of the guide channel is connected to a vibratory feeder. An O-ring 88 in the vibratory feeder is transported to the positioning groove 57 through the guide channel. After the O-ring 88 falls into the positioning groove 57, the ninth slider 372 pushes the O-ring 88 to one end of the positioning groove 57 to position it. A third translation and lifting mechanism 375, connected to the valve core moving assembly 34 and the valve stem moving assembly 36, is located on the second working platform 31 near the sixth base 371. 5. The third translation and lifting mechanism 375 is equipped with a fourth gripper 373. The fourth gripper 373 is translated and lifted by the third translation and lifting mechanism 375. The gripper of the fourth gripper 373 moves relative to the third translation and lifting mechanism 375 to grip the O-ring 88. Then, the O-ring 88 is transferred to the valve stem 86 on the positioning seat 312 by the third translation and lifting mechanism 375 and sleeved on the valve stem 86. The second working platform 31 is equipped with a clamping mechanism 374 near the positioning seat 312. The clamping mechanism 374 includes a driving member. The driving member is equipped with two relatively movable grippers. The two grippers move relative to each other to clamp the valve stem 86 on the positioning seat 312, thereby fixing the valve stem 86 and preventing the valve stem 86 from moving when the O-ring 88 is sleeved.

[0069] The second translation and lifting mechanism 364 and the third translation and lifting mechanism 375 have the same structure and principle as the first translation and lifting mechanism 32, and will not be described in detail here.

[0070] Second photoelectric sensors 33 are installed on the second working platform 31 at the valve core moving assembly 34, spring moving assembly 35, and valve stem moving assembly 36 to monitor whether the valve core 84, spring 85, and valve stem 86 are properly assembled. The specific model, structure, and implementation principle of the second photoelectric sensor 33 are all conventional technologies available on the market and will not be described in detail here.

[0071] The second transfer component 38 is fixed on the second working platform 31. Its structure and working principle are the same as the first transfer component 23. The difference is that the second transfer component 38 grabs the assembled nozzle into the mounting hole at the top of the spray rail body 81.

[0072] The nozzle mechanism 3 also includes a screwing assembly 39, such as Figure 10 As shown, the screwing assembly 39 includes a first fixed base 391, which is located on the first working platform 21 and on one side of the conveyor line 1. A first lifting platform 392 is connected to the first fixed base 391. The first lifting platform 392 includes a first platform, a first guide rod, and a first lifting cylinder. The first platform moves up and down along the first guide rod under the drive of the first lifting cylinder, enabling the first lifting platform 392 to move up and down relative to the first fixed base 391. A driving component is provided on the first fixed base 391. A telescopic sleeve 394 is provided between the first fixed base 391 and the first lifting platform 392. The fixed end of the telescopic sleeve 394 is connected to the output end of the driving component through a first universal joint 393. The movable end of the telescopic sleeve 394 is connected to a second universal joint 395. The other end of the second universal joint 395 is connected to a screwing head 396. The screwing head 396 includes a sleeve 3961, a telescopic head 3962, and an elastic... Part 3963: A through hole is opened on the first lifting platform 392. The sleeve 3961 is sleeved in the through hole through a bearing, so that the sleeve 3961 can slide back and forth along the through hole. One end of the sleeve 3961 is connected to the second universal joint 395, and the other end is sleeved to the telescopic head 3962. The telescopic head 3962 can move back and forth along the sleeve 3961. The elastic element 3963 is sleeved on the outside of the telescopic head 3962, and one end of the elastic element 3963 abuts against the end of the telescopic head 3962. One end of the telescopic head 3962 is against the sleeve 3961, causing the telescopic head 3962 to reciprocate along the sleeve 3961. The top end of the telescopic head 3962 has a sleeve hole, which fits onto the top end of the valve stem 86. The telescopic sleeve 394 rotates and extends under the drive of the drive component, causing the sleeve 3961 to rotate and extend. The sleeve 3961 drives the telescopic head 3962 to rotate, and the telescopic head 3962 drives the valve stem 86 to rotate, thereby tightening the valve stem 86 onto the spray rail body 81.

[0073] It should be noted that there are four valve stems 86 installed on the main body 81 of the spray rail, and there are also four corresponding screw heads 396, which correspond one-to-one with the valve stems 86.

[0074] like Figure 9 As shown, the conveyor line 1 includes guide rails 11 distributed along the conveying direction. The guide rails 11 have grooves for placing and allowing the spray rail body 81 to slide. Below the guide rails 11, a guide slide rail 12 parallel to the guide rails 11 is provided. A first sliding block 13 is slidably connected to the guide slide rail 12. A second ball screw pair 16 is also provided on the guide slide rail 12. The first sliding block 13 is simultaneously fixed to the second ball screw pair 16, causing the first sliding block 13 to reciprocate along the guide slide rail 12 as the second ball screw pair 16 rotates. A second sliding block 14 is slidably connected to the first sliding block 13, and the first sliding block 13 and the second sliding block 14 are connected by a track and a slider. The sliding connection method achieves relative sliding. The second sliding block 14 is connected to a driving component to drive the second sliding block 14 to move toward the spray rail body 81 on the guide rail 11. The second sliding block 14 is provided with a locking component 15. One end of the locking component 15 is connected to the second sliding block 14, and the other end extends out to two clamping surfaces, which respectively abut against the two ends of the spray rail body 81 to limit the spray rail body 81. As the second sliding block 14 drives the locking component 15 to move along the guide rail 12, the locking component 15 drives the spray rail body 81 to move, so that the spray rail body 81 is conveyed along the conveyor line 1, realizing that the spray rail body 81 moves along the conveyor line 1 in sequence to each component for assembly.

[0075] The coil mechanism 4 includes a second feed tray 41, such as Figure 8 As shown, coils 89 are arranged on the second material tray 41. A third transfer component 42 is provided above the second material tray 41 to grab the coils 89 and put them onto the valve stem 86. The third transfer component 42 is fixed on the first working platform 21 and close to the conveyor line 1. Its structure and working principle are the same as the first transfer component 23. The difference is that the third transfer component 42 grabs the coils 89 on the second material tray 41 and puts them onto the valve stem 86. This will not be described in detail here.

[0076] Along the conveyor line 1, the first working platform 21 is also equipped with a first photoelectric sensor 43 for detecting the coil 89 in place. The specific model, structure and implementation principle of the first photoelectric sensor 43 are all conventional technologies on the market, and will not be described in detail here.

[0077] like Figures 11-14As shown, the snap ring mechanism 5 includes a guide seat 51 fixed to the first working platform 21. The guide seat 51 has a guide groove 52 for accommodating and positioning the snap ring 87. The guide seat 51 has a guide channel above the guide groove 52. One end of the guide channel is connected to a vibratory plate for providing the snap ring 87, and the other end extends directly above the guide groove 52. The snap ring 87 on the vibratory plate falls into the guide groove 52 along the guide channel. A limiting seat 53 is provided on one side of the guide seat 51 at the opening of the guide groove 52. The limiting seat 53 has a limiting groove 54 adapted to the snap ring 87. The limiting groove 54 is connected to the guide groove 52. A push rod 55 is provided on the guide seat 51. The push rod 55 can reciprocate along the guide groove 52 under the drive of the driving component. One end of the push rod 55 abuts against the guide groove. On one side of the retaining ring 87 inside 52, under the push of the push rod 55, the retaining ring 87 is pushed from the guide groove 52 into the limiting groove 54. The number of limiting grooves 54 is the same as the number of valve rods 86 on the spray rail body 81, so that the valve rods 86 on the spray rail body 81 can be assembled at one time. Therefore, the limiting seat 53 slides through the cooperation of the track and the slider, so that the limiting seat 53 can slide relative to the guide seat 51, so that the multiple limiting grooves 54 of the limiting seat 53 can be connected to the guide groove 52 in sequence, so that each limiting groove 54 has a corresponding retaining ring 87. The first platform is provided with a second lifting platform 56 that performs lifting action relative to the conveyor line 1. The second lifting platform 56 includes a second platform fixed to the first working platform 21, a second guide rod, and a second lifting cylinder. Driven by the second lifting cylinder, the platform moves up and down along the second guide rod, enabling the second lifting platform 56 to move up and down relative to the second fixed seat. A positioning groove 57 is provided at one end of the second lifting platform 56 near the conveyor line 1. One end of the positioning groove 57 is open, and the bottom surface of the other end is an arc surface, allowing the outer wall of the top of the valve stem 86 to abut against the arc surface for positioning. The number of positioning grooves 57 is the same as the number of limiting grooves 54, and they correspond one-to-one. A snap ring moving assembly 58 is provided on the first working platform 21. The snap ring moving assembly 58 includes a seventh base 581 fixed to the first working platform 21, a tenth slider 582 slidably connected to the seventh base 581, and an eleventh slider 583 slidably connected to the tenth slider 582. Block 583 moves up and down along the tenth slider 582. The eleventh slider 583 is provided with a sleeve 584 and a lifting column 585. The sleeve 584 is fixed on the eleventh slider 583, and the lifting column 585 is sleeved inside the sleeve 584. Driven by the driving component, the lifting column 585 can move up and down along the sleeve 584. The end of the lifting column 585 is cylindrical and its outer diameter is slightly larger than the inner diameter of the retaining spring 87, so that the end of the lifting column 585 can be inserted into the retaining spring 87 and open the retaining spring 87. The retaining spring 87 is locked at the end of the lifting column 585, realizing the gripping of the retaining spring 87. That is, the retaining spring 87 is moved to the limiting groove 54 of the limiting seat 53 through the retaining spring moving assembly 58, and the end of the lifting column 585 extends into the limiting groove 54, and the lifting column 585 opens the retaining spring 87 in the limiting groove 54.This allows the retaining spring 87 to engage with the lifting column 585, enabling it to be grasped and moved directly above the positioning groove 57 of the second lifting platform 56. As the lifting column 585 rises, the sleeve 584 prevents the retaining spring 87 from rising with it, thus detaching it from the column. The detached retaining spring 87 falls into the positioning groove 57. The second lifting platform 56 has a pushing member 586 near the positioning groove 57, including a pushing block located within the groove. This pushing block can slide along the groove. Under the push of the driving member, the sliding block reciprocates along the groove. Because the retaining spring 87 has an opening, the sliding block pushes the retaining spring 87 towards the valve stem 86 from one side. The opening of the retaining spring 87 engages with the top outer wall of the valve stem 86, thus connecting the retaining spring 87 to the valve stem 86.

[0078] It should be noted that a pressing component is provided directly above the limiting groove 54. The pressing component includes a driving component fixed on the guide seat 51. A pressing rod 59 is provided at the output end of the driving component. One end of the pressing rod 59 is connected to the output end of the driving component, and the other end extends vertically to directly above the retaining spring 87 in the limiting groove 54. Under the drive of the driving component, the end of the pressing rod 59 directly presses against the retaining spring 87, pressing the retaining spring 87 in the limiting groove 54 flat, and preventing the retaining spring 87 from being pushed into the limiting groove 54 by the push rod 55 to form an uneven placement.

[0079] It also includes a sorting mechanism 6, such as Figure 8 As shown, the sorting mechanism 6 includes a vision inspection component 61, a tray 62, and a fourth transfer component 63 in sequence along the conveying direction of the conveyor line 1. The vision inspection component 61 is used to inspect the appearance of the gas injection rail assembly 8 and to check whether it is assembled in place. In this embodiment, the specific model, structure, and implementation principle of the vision inspection component 61 are all conventional technologies on the market and will not be described in detail here. The sorting mechanism 6 also includes a tray 62, which is used to place qualified injection rail assemblies 8. The fourth transfer component 63 picks up the qualified injection rail assemblies 8 and puts them onto the tray 62. After being inspected by the vision inspection component 61, unqualified products are conveyed to the end of the conveyor line 1 for processing.

[0080] The fourth transfer component 63 is fixed on the first working platform 21 and close to the conveyor line 1. Its structure and working principle are the same as the first transfer component 23. The difference is that the fourth transfer component 63 is used to grip the qualified spray rail component 8. The gripper is designed to hold the spray rail component 8, so it is different from the gripper of the first transfer component 23. It should be noted that the grippers of the transfer components in this application can be any shape and structure with clamping function, which will not be described in detail here.

[0081] The first material tray 22 and the second material tray 41 are respectively equipped with material feeding conveyor lines 7, making material feeding from the first material tray 22 and the second material tray 41 more convenient and faster. Figure 7As shown, each feeding conveyor line 7 includes two parallel conveyor chains 73. A first bracket 71 and a second bracket 72 are provided between the two conveyor chains 73. Both the first bracket 71 and the second bracket 72 have lifting rods 75 at their bottoms, allowing them to lift. The first bracket 71 and the second bracket 72 are arranged sequentially along the conveying direction of the conveyor chains 73. A third lifting platform 76 is provided on both sides of the first bracket 71. A telescopic rod 77 is provided at the bottom of the third lifting platform 76, allowing it to lift. A second clamping block 78 is provided on both sides of the third lifting platform 76. In this embodiment, there are four second clamping blocks 78, located at the four corners of the third lifting platform 76. A driving member is provided on the third lifting platform 76 corresponding to each second clamping block 78. The moving part drives the clamping blocks on both sides to move relative to each other, that is, to move back and forth towards the bracket, thereby clamping the material tray on the first bracket 71. The second bracket 72 is provided with support blocks 79 on both sides. In this embodiment, there are four support blocks 79, which are located at the four corners of the second bracket 72 to support the material tray on the second bracket 72. The conveyor chain 73 is located in front of the second bracket 72 and has a loading position. A limiting block is provided on one side of the loading position. A driving part is provided on the limiting block. The driving part drives the limiting block to move towards the first material tray 22. A limiting hole is opened on one side of the first material tray 22. The limiting block is inserted into the limiting hole of the first material tray 22 under the drive of the driving part, thereby positioning the first material tray 22 at the loading position and preventing the first material tray 22 from shifting, so that the first transfer component 23 can accurately clamp the spray rail body 81.

[0082] It should be noted that the first material tray 22 and the second material tray 41 in this invention are both rectangular material trays. Therefore, the corresponding second clamping block 78 and support block 79 are distributed at the four corners of the material tray. When the first material tray 22 and the second material tray 41 are other shapes, the second clamping block 78 and support block 79 can appear in an adapted form.

[0083] The working principle of the material feeding conveyor line 7 is as follows: an empty first material tray 22 is placed on the first bracket 71. The first bracket 71 rises to drive the first material tray 22 to rise, and the spray rail body 81 is placed in the first material tray 22. Then the first bracket 71 descends until the first material tray 22 is placed on the conveyor chains 73 on both sides. The first material tray 22 is conveyed to the loading position through the conveyor chains 73. After the first material tray 22 on the loading position is empty, it is manually placed on the second bracket 72. The second bracket 72 rises, and the first material tray 22 rises along with the second bracket 72, so that the empty first material tray 22 is separated from the conveyor chain 73 without interfering with the continued conveying of the conveyor chain 73. After the first bracket 71 is empty, the empty first material tray 22 on the second bracket 72 is placed on the first bracket 71, and the spray rail body 81 is placed in the first material tray 22. This operation is repeated.

[0084] The principle and structure of the feeding conveyor line 7 on the second tray 41 used to place the coil 89 are the same, and will not be described in detail here.

[0085] The working principle of this invention is as follows: the first transfer component 23 picks up the spray rail body 81 in the first material tray 22 and places it onto the rotating component 24. The spray rail assembly 8 is positioned by the rotating component 24. Then, the air inlet moving component 25 and the plug moving component 26 provide and install the air inlet 82 and the plug 83 onto both ends of the spray rail body 81, respectively. Then, the valve core moving component 34, the spring moving component 35, the valve stem moving component 36, and the O-ring moving component 37 on the nozzle mechanism 3 assemble the valve core 84, the spring 85, the valve stem 86, and the O-ring 88 to form a complete nozzle. Then, the second transfer component 38 picks up the nozzle and inserts it into the spray rail body 81. Finally, the screwing component... 39. Tighten the nozzle to the spray rail body 81. Then, the conveyor line 1 transports the spray rail body 81 to the coil mechanism 4. The third transfer component 42 on the coil mechanism 4 grabs the coil 89 on the second tray 41 and inserts it into the valve stem 86. Then, the conveyor line 1 transports the spray rail body 81 to the snap ring mechanism 5. The snap ring mechanism 5 assembles the snap ring 87 between the coil 89 and the valve stem 86 to form a complete spray rail assembly 8. The spray rail assembly 8 is transported to the sorting mechanism 6 through the conveyor line 1. The sorting mechanism 6 performs visual inspection on the spray rail assembly 8 to determine whether it is qualified. Qualified spray rail assemblies 8 are grabbed by the fourth transfer component 63 and placed into the tray 62. Unqualified spray rail assemblies 8 are transported by the conveyor line 1 to be processed separately.

[0086] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
