An automated assembly apparatus for a perfume nozzle fitting

Abstract

This invention belongs to the field of nozzle connector assembly technology, specifically an automated assembly device for perfume nozzle connectors. It includes a workbench with a moving cavity. A rotating gear is rotatably connected within the moving cavity, and a one-way motor is externally connected to the rotating gear. A support base is fixedly connected to the center of the moving cavity, and a rotating sleeve is rotatably connected between the lower top surface of the support base and the moving cavity. This invention uses the opposing movement of clamping plates to clamp a straw that has deformed and blocked the insertion channel within a limiting block. Under the rotation of the rotating shaft, the rotating plate drives the clamping plates on it to rotate together, positioning the straw held by the clamping plates above a collection groove. This clears the straw blocking the insertion channel, keeping the insertion channel unobstructed. Simultaneously, when the clamping plates reset, the straws held on the clamping plates fall into the collection groove, thus collecting failed insertion straws and maintaining a clean working environment.

Description

Technical Field

[0001] This invention belongs to the field of nozzle connector assembly technology, specifically an automated assembly device for perfume nozzle connectors. Background Technology

[0002] The perfume nozzle connector automated assembly equipment is a device used for the automated production and assembly of perfume sprayer connectors. Its purpose is to improve the efficiency of perfume nozzle connector production, ensure the quality of the assembled perfume nozzle connectors, and reduce production costs.

[0003] In the existing technology, firstly, the spray core with the nozzle bottle mouth interface is connected to the sealing ring, so that the sealing ring is snapped into the nozzle bottle mouth interface. Then, it is placed in the limiting mold on the pressing plate by a mechanical gripper, and is pressed by a pressing device to make the sealing ring completely embedded in the top of the nozzle bottle mouth interface, thereby sealing the connection between the nozzle bottle mouth interface and the spray core. Next, the nozzle cap is placed on top of the spray core by a mechanical gripper and pressed to make the inside of the nozzle cap insert into the top of the spray core. Then, it is fixed on the limiting mold by a pressing device, and the straw is connected to the spray core by an insertion machine, while cutting off the excess straw. Finally, the assembled perfume nozzle connector is collected by a mechanical gripper.

[0004] Existing automated perfume nozzle connector assembly equipment still has some problems in practical application. In the straw insertion machine of existing automated perfume nozzle connector assembly equipment, during the straw insertion process, because the straws are rolled into a circular coil during storage, some straws will be slightly bent after long-term storage. As a result, when the straw insertion machine inserts the straw, the top of the straw cannot be fully aligned with the bottom end of the spray cartridge, resulting in insertion failure. The failed straws are deformed and stuck at the insertion interface of the straw insertion machine, so when the straw insertion machine continues to insert straws, even normal straws may not be able to be correctly inserted into the bottom end of the spray cartridge, thus affecting the assembly efficiency and quality of perfume nozzle connectors.

[0005] Therefore, the present invention provides an automated assembly device for perfume nozzle connectors. Summary of the Invention

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention cuts the straw by moving the cutting blocks in opposite directions, preventing the straw from bending due to unidirectional cutting during the cutting process. This reduces the bending of the straw after cutting, and further reduces the problem of straw end bending leading to insertion failure when the straw is inserted into the nozzle bottle mouth interface placed on the upper limiting mold of the displacement block, thus improving the product yield.

[0021] 2. This invention detects whether the limiting mold above the displacement block is in direct contact with the two contact blocks, and whether the nozzle core of the nozzle bottle mouth interface placed on it is successfully inserted into the straw. This avoids an increase in defective products caused by unsuccessful straw insertion, and further prevents the straw from blocking the subsequent insertion of the nozzle core of the nozzle bottle mouth interface, thus preventing the insertion failure.

[0022] 3. This invention uses the opposing movement of clamping plates to hold the straw that has deformed and blocked the insertion channel within the limiting block two. Under the action of the rotating shaft, the rotating plate drives the clamping plates on it to rotate together, so that the straw held by the clamping plates is above the collection groove. This clears the straw that has deformed and blocked the insertion channel within the limiting block two after failed insertion, keeping the insertion channel of the straw unobstructed. At the same time, when the clamping plates reset, the straw held on the clamping plates falls into the collection groove, thereby collecting the failed insertion straws and maintaining a clean working environment. Furthermore, the collected failed insertion straws can be recycled and reused, reducing production costs. Attached Figure Description

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] Example 1

[0046] like Figures 1 to 16As shown in the embodiment of the present invention, an automated assembly device for perfume nozzle connectors includes a workbench 1. A motion cavity 11 is formed on the workbench 1. A rotating gear 12 is rotatably connected inside the motion cavity 11. A unidirectional motor is externally connected to the rotating gear 12. A support base 13 is fixedly connected to the middle of the motion cavity 11. A rotating sleeve 14 is rotatably connected between the top lower surface of the support base 13 and the motion cavity 11. A transmission gear 15 is fixedly connected to the bottom surface of the rotating sleeve 14. The transmission gear 15 meshes with the rotating gear 12. The top surface of the rotating sleeve 14... A pressing plate 16 is fixedly connected to the surface of the workbench 1. Multiple limiting molds 17 are fixedly connected to the side wall of the pressing plate 16. Three support platforms 18 are fixedly connected to the top of the workbench 1. The three support platforms 18 are arranged in a circumferential array around the rotating sleeve 14. Mechanical grippers 19 are provided on each of the three support platforms 18. Multiple fixing plates 110 are provided at the top of the support base 13. Pressing devices 111 are symmetrically arranged on each of the multiple fixing plates 110. A suction tube insertion assembly is provided on the top of the side near the workbench 1. The suction tube insertion assembly is used to insert the suction tube into the bottom end of the spray core and cut the suction tube to a predetermined length.

[0047] Specifically, existing automated assembly equipment for perfume nozzle connectors still has some problems in practical application. Because straws are coiled into circular loops during storage, some straws may be slightly bent after long-term storage. This causes the top of the straw to not be fully aligned with the bottom of the spray cartridge when the straw is inserted by the straw insertion machine, resulting in insertion failure. The failed straw is deformed and stuck in the limiting block 243 of the straw insertion machine, making it impossible for a normal straw to be correctly inserted into the bottom of the spray cartridge when the straw insertion machine continues to insert straws, thus affecting the assembly efficiency and quality of perfume nozzle connectors.

[0048] Therefore, this invention solves this problem by setting a corresponding structure. First, the spray core with the nozzle bottle mouth interface is connected to the sealing ring, so that the sealing ring is inserted into the nozzle bottle mouth interface. Then, the mechanical gripper 19 places it in the limiting mold 17 on the pressing plate 16. At this time, the one-way motor connected to the rotating gear 12 is started. The rotation of the output shaft of the one-way motor drives the rotating gear 12 to rotate, which in turn drives the transmission gear 15 to rotate, thereby driving the rotating sleeve 14 to rotate. The pressing plate 16 rotates with the rotating sleeve 14, thereby driving the limiting mold 17 on the pressing plate 16 to rotate. The positioning molds 17 rotate synchronously with the pressing plate 16. Initially, the number of positioning molds 17 is the same as the number of teeth of the transmission gear 15. The pressing device 111 on the fixing plate 110 is located directly above one of the positioning molds 17, and the pressing device 111 and the positioning mold 17 are on the same vertical line. When the rotating gear 12 rotates one revolution, as mentioned above, the positioning molds 17 rotate. At this time, one of the positioning molds 17 is located below the pressing device 111. Then, the pressing device 111 is activated to squeeze, thereby making the sealing ring completely embedded in the nozzle bottle. The top of the nozzle bottle neck interface is sealed, thus sealing the connection between the nozzle bottle neck interface and the spray core. Then, the rotating gear 12 rotates one more revolution, causing the sealed nozzle bottle neck interface, after the sealing ring is assembled, to move together with the limiting mold 17. At this time, the mechanical gripper 19 places the nozzle cap above the spray core inside the nozzle bottle neck interface, located on the movement trajectory of the mechanical gripper 19, and the pressing device 111 presses it to insert the inside of the nozzle cap into the top of the spray core. Subsequently, the rotating gear 12 rotates one more revolution, causing the limiting mold 17 to shift, and the pressing device 111 presses the assembled nozzle bottle neck interface... Fixed on the limiting mold 17, the straw is connected to the spray core through the straw insertion assembly, and the excess straw is cut off, thus completing the assembly of the perfume nozzle connector. Then, the rotating gear 12 continues to rotate one revolution, causing the limiting mold 17 where the assembled perfume nozzle connector is located to continue to move, and the assembled perfume nozzle connector is collected by the mechanical gripper 19. As the rotating gear 12 moves, there are no more perfume nozzle connector parts to be assembled on the limiting mold 17 until the limiting mold 17 returns to the initial position, and then the assembly continues, and so on.

[0049] like Figure 1 and Figure 2 As shown, the rotating gear 12 in this embodiment is a two-tooth gear, the pressing device 111 is located above the limiting mold 17, and the limiting mold 17 is located on the movement trajectory of the mechanical gripper 19.

[0050] Specifically, the rotating gear 12 is a two-tooth gear. Initially, the number of limiting molds 17 is the same as the number of teeth of the transmission gear 15, so that when the rotating gear 12 rotates once, the transmission gear 15 rotates by the distance of two teeth, thereby controlling the displacement distance of the limiting molds 17 on it. The pressing device 111 is located above the limiting mold 17. Initially, the pressing device 111 and the limiting mold 17 are on the same vertical line, so that the pressing device 111 can accurately press down the perfume nozzle connector parts on the limiting mold 17. The limiting mold 17 is located on the movement trajectory of the mechanical gripper 19, so that the mechanical gripper 19 places the perfume nozzle connector parts to be assembled on the limiting mold 17.

[0051] like Figures 1 to 3 and Figures 5 to 10 As shown, in this embodiment, a limiting groove 21 is formed on one side of the top surface of the workbench 1. An electric telescopic rod 22 is fixedly connected in the limiting groove 21. A limiting block 23 is fixedly connected on the top surface of the workbench 1 near the rotating sleeve 14. The limiting block 23 is located between the limiting groove 21 and the rotating sleeve 14. A sliding groove 24 is formed in the limiting block 23. A contact plate 25 is fixedly connected on the bottom side of the limiting block 23 away from the rotating sleeve 14. The electric telescopic rod 22 passes through the contact plate 25. A displacement block 26 is slidably connected in the sliding groove 24. A limiting block 243 is fixedly connected to the top of the displacement block 26.

[0052] The displacement block 26 has symmetrically formed displacement grooves 27, and each of the two displacement grooves 27 is slidably connected to a contact rack 213. The displacement block 26 also has a displacement groove 245, and a transmission rack 214 is slidably connected to the displacement groove 245. The displacement groove 245 is connected to the two displacement grooves 27. A guide gear rod 28 is rotatably connected at the connection between the displacement groove 245 and the two displacement grooves 27. The guide gear rod 28 is composed of a guide gear and a rotating shaft. The guide gear on the guide gear rod 28 rotates between the inner walls of the displacement grooves 27. The transmission rack 214 meshes with the guide gears on the two guide gear rods 28. Each contact rack 213 meshes with a guide gear on one guide gear rod 28.

[0053] A rotating groove 224 is provided inside the displacement block 26, which is connected to the second displacement groove 245. The rotating shaft on the guide gear rod 28 at the top of the displacement block 26 rotates between the rotating groove 224 and the second displacement groove 245. A guide groove 29 is provided between the rotating shaft on the guide gear rod 28 at the top of the displacement block 26 and the guide gear, so that the rotating shaft on the guide gear rod 28 at the top of the displacement block 26 is no longer fixed to the guide gear. At the same time, a groove is formed between the rotating shaft and the guide gear. A fixing rod 210 is fixedly connected between the inner walls of the groove in the rotating shaft. A second abutment plate 211 is rotatably connected to the surface of the fixing rod 210. The second abutment plate 211 rotates in the guide groove 29. A return spring 212 is fixedly connected between the side of the second abutment plate 211 near the middle of the guide gear rod 28 and the inner wall of the guide groove 29.

[0054] Specifically, during the straw insertion process, the perfume nozzle assembly to be assembled with the straw on the limiting mold 17 is located above the displacement block 26. It is fixed to the limiting mold 17 by the pressing device 111. At this time, the electric telescopic rod 22 is activated, causing the displacement block 26 to move towards the limiting mold 17 within the sliding groove 24 until it contacts the limiting mold 17. Initially, the abutting rack 213 at the top of the displacement block 26 protrudes from the top of the displacement block 26. Then, the limiting block 243 is inserted into the limiting mold 17. During this process, the abutting rack 213 at the top of the displacement block 26 contacts the limiting mold 17, causing the abutting rack 213... Moving towards the bottom of displacement block 26, the guide gear rod 28 is composed of a guide gear and a rotating shaft. Under the action of the guide groove 29, the guide gear rod 28 located at the top of displacement block 26 is no longer fixed. At the same time, a groove is formed between the rotating shaft and the guide gear. Because the guide gear on the guide gear rod 28 rotates between the inner walls of the displacement groove 27, when the abutting rack 213 at the top of displacement block 26 is displaced, it drives the guide gear on the guide gear rod 28 located at the top of displacement block 26 to rotate, thereby driving the transmission rack 214 to move upward. The rotation of the guide gear on the guide gear rod 28 located at the bottom of displacement block 26 then drives the abutting rack 213 meshing with it to move downward.

[0055] During the clockwise rotation of the guide gear rod 28 at the top of the displacement block 26, the inner wall of the groove in the guide gear on the guide gear rod 28 abuts against the abutment plate 211, causing the abutment plate 211 to rotate around the fixed rod 210 and compress the return spring 212, so that the abutment plate 211 is retracted into the groove in the rotating shaft rod until the inner wall of the groove of the guide groove 29 in the guide gear passes through the abutment plate 211. At this time, the abutment plate 211 enters the groove of the guide groove 29 in the next guide gear. At this time, the return spring 212 is released elastically to reset the abutment plate 211. This process is repeated to keep the rotating shaft rod on the guide gear rod 28 stationary.

[0056] When the electric telescopic rod 22 retracts, the abutting rack 213 at the top of the displacement block 26 retracts into the displacement groove 27 when the top of the displacement block 26 abuts against the limiting mold 17. Under the action of the guide gear rod 28 and the transmission rack 214, the abutting rack 213 at the bottom of the displacement block 26 extends. During the downward movement of the displacement block 26, when the abutting rack 213 at the bottom of the displacement block 26 abuts against the abutting plate 25, the bottom abutting rack 213 moves upward and drives the bottom guide gear rod 28 to rotate, causing the transmission rack 214 to move downward, thereby driving the guide gear on the top guide gear rod 28 to rotate, and thus driving the top abutting plate 25 to rotate. As rack 213 moves upward and returns to its initial position, during the process of the guide gear on the top guide gear rod 28 driving the top abutting rack 213 to move, as mentioned above, the guide gear rotates in the opposite direction at this time. The inner wall of the groove in the guide gear abuts against the second abutting plate 211, causing the second abutting plate 211 to rotate around the fixed rod 210 as the axis and elastically stretch the first return spring 212. This causes the second abutting plate 211 to abut against the inner wall of the groove in the rotating shaft rod, preventing the inner wall of the groove in the guide gear from being stuck by the second abutting plate 211. This causes the guide gear to be relatively fixed to the rotating shaft rod, thereby driving the rotating shaft rod on the guide gear rod 28 located at the top of the displacement block 26 to rotate counterclockwise.

[0057] like Figures 7 to 11As shown, in this embodiment, a guide groove 215 is provided inside the displacement block 26. The guide groove 215 is connected to the limiting block 243 and the displacement groove 245. A displacement block 216 is fixedly connected to the side of the top of the transmission rack 214 away from the guide gear rod 28. The displacement block 216 slides in the guide groove 215. A motion groove 246 is provided inside the displacement block 216. A clamping block 217 is slidably connected inside the motion groove 246. The shape of the motion groove 246 matches the shape of the clamping block 217. Wedge blocks 218 are fixedly connected to the top and bottom surfaces of the clamping block 217. Wedge-shaped blocks 219 are fixedly connected to both the top and bottom surfaces of 215. The wedge-shaped blocks 219 are all on the movement trajectory of the wedge-shaped block 218. A clamping block 223 is slidably connected in the guide groove 215. The clamping block 223 is located on the side of the clamping block 217 away from the transmission rack 214. The clamping block 217 is inserted into the clamping block 223. A telescopic groove 220 is opened at the bottom of the guide groove 215. A moving rod 221 is slidably connected in the telescopic groove 220. The top end of the moving rod 221 is fixedly connected to the bottom end of the clamping block 223. A telescopic spring 222 is fixedly connected between the upper surface of the bottom end of the moving rod 221 and the inner wall of the top of the telescopic groove 220.

[0058] Specifically, during the upward movement of the transmission rack 214, it drives the displacement block 216 fixed to it to move together, causing the displacement block 216 to slide in the guide groove 215. At this time, the clamping block 217 and the clamping block 223 are inserted into each other. As the displacement block 216 moves, it drives the clamping block 217 sliding in it to move together, causing the clamping block 223 to move together with the clamping block 217. Through the fixation of the clamping block 223 and the moving rod 221, the movement of the clamping block 223 drives the moving rod 221 to move together, causing the moving rod 221 to slide in the telescopic groove 220 and elastically compress the telescopic spring 222, thereby driving the clamping block 217 and the moving rod 221 to move together. The straw held between clamping blocks 223 moves toward the limiting mold 17 until the wedge block 218 at the top of clamping block 217 abuts against the wedge block 219 at the top of the guide groove 215. At this time, the straw passes through the limiting block 243 and is inserted into the nozzle bottle mouth interface on the limiting mold 17 above it. At the same time, the abutment between wedge block 218 and wedge block 219 causes clamping block 217 to slide away from clamping block 223 in the movement groove 246. Then clamping block 217 and clamping block 223 no longer hold the straw, causing the telescopic spring 222 to release elastically, thereby causing the movement rod 221 and clamping block 223 to return to the initial position.

[0059] When the electric telescopic rod 22 retracts, the displacement block 26 moves downward, which in turn drives the clamping block 217 to move downward through the downward displacement of the transmission rack 214 until the displacement block 26 contacts the contact plate 25. At this point, the clamping block 217 returns to its initial position. During this process, the wedge block 218 at the bottom of the clamping block 217 contacts the wedge block 219 at the bottom of the guide groove 215, causing the clamping block 217 to move towards the clamping block 223 and engage with it. This allows the clamping block 217 and the clamping block 223 to clamp the straw between them, thus fixing the straw in place.

[0060] like Figure 5 , Figure 6 and Figure 12 As shown, in this embodiment, a rotating bevel gear 225 is fixedly connected to the surface of the rotating shaft 28 on the guide gear rod 224 located in the rotating groove 224. A transmission bevel gear rod 226 is rotatably connected in the rotating groove 224, and the transmission bevel gear rod 226 meshes with the rotating bevel gear 225. A rotating column 227 is fixedly connected to the surface of the transmission bevel gear rod 226. A guide groove 228 is formed on the surface of the rotating column 227. A displacement block 229 is slidably connected in the rotating groove 224. The displacement block 229 is located above the rotating column 227, and the side of the displacement block 229 closest to the guide gear rod 28 is between the displacement block 229 and the inner wall of the rotating groove 224. A return spring 230 is symmetrically fixedly connected. A guide rod 231 is fixedly connected to the bottom of the displacement block 229. The guide rod 231 slides in the guide groove 228. A cutting groove 244 is opened on the displacement block 26. The cutting groove 244 is connected to the guide groove 215 and the rotation groove 224. A displacement block 232 is slidably connected in the cutting groove 244. One side of the displacement block 232 is fixedly connected to the displacement block 229. A displacement plate 233 is fixedly connected to the side of the displacement block 232 near the limiting block 243. The displacement plate 233 slides in the communication between the cutting groove 244 and the guide groove 215.

[0061] Specifically, when the guide gear rod 28 at the top of displacement block 1 26 rotates, it drives the transmission bevel gear rod 226 to rotate as well, causing the rotating column 227 to rotate along with the transmission bevel gear rod 226. This causes the guide groove 3 228 to shift with the rotation of the rotating column 227, which in turn causes the guide rod 231 to move towards the guide gear rod 28 according to the shape of the guide groove 3 228. This, in turn, causes displacement block 3 229 to move along with the guide rod 231 and elastically compress the reset spring 230. The movement of displacement block 3 229 then causes displacement block 4 232 to shift towards the limit block 243 within the cutting groove 244. This, in turn, causes displacement plate 1 233 to move along with displacement block 4 232 until the rotating column 227 rotates one revolution. At this point, under the elastic release of the reset spring 230 and the guiding action of the guide groove 3 228, the guide rod 231 and displacement block 3 229 return to their initial positions, thereby causing displacement block 4 232 and the displacement plate 1 233 fixed on it to reset.

[0062] like Figures 12 to 14 As shown, in this embodiment, the displacement plate 233 is symmetrically provided with contraction grooves 234. A limiting plate 235 is slidably connected within the contraction groove 234. An anti-collision spring 236 is symmetrically fixedly connected between the limiting plate 235 and the contraction groove 234. A displacement rack 237 is fixedly connected to the side of the limiting plate 235 away from the anti-collision spring 236. The displacement rack 237 is slidably connected within the contraction groove 234. Two rotating rods 238 are rotatably connected to the middle of the displacement plate 233, and the surfaces of the two rotating rods 238 are symmetrical. The device has guide thread grooves 240, and two guide thread grooves 240 are threadedly connected to cutting blocks 241. The two ends of the rotating rod 238 away from the displacement plate 233 are fixedly connected to transmission gears 239. The transmission gears 239 mesh with the displacement rack 237. The surfaces of the two rotating rods 238 are fixedly connected to transmission wheels 247. The two transmission wheels 247 are connected by a transmission belt 242. The transmission belt 242 is symmetrically connected to the two ends of the two rotating rods 238. The structures inside the displacement block 26 are all symmetrically arranged.

[0063] Specifically, as the displacement plate 233 moves towards the limiting block 243 within the cutting groove 244, when the displacement rack 237 contacts the inner wall of the cutting groove 244, the displacement plate 233 continues to move, causing the displacement rack 237 to slide towards the displacement block 232 within the contraction groove 234. This, in turn, causes the limiting plate 235 to move along with it and elastically compress the contact spring 236. During this process, because the displacement rack 237 meshes with the transmission gear 239, it drives the movement away from the displacement block 232. Rotating rod 238 rotates, and through the transmission belt 242 on the transmission wheel 247 fixed on the surface of rotating rod 238, another rotating rod 238 rotates together. This causes the cutting block 241 to move closer to the middle of rotating rod 238 under the guidance of the guide thread groove 240, so that the two cutting blocks 241 move towards each other until the displacement rack 237 is completely retracted into the shrinkage groove 234. At this time, the two cutting blocks 241 collide, thereby cutting off the suction tube which is in the same vertical plane as the middle of rotating rod 238.

[0064] This invention cuts the straw by moving the cutting block 241 in opposite directions, preventing the straw from bending due to unidirectional cutting during the cutting process. This reduces the bending of the straw after cutting, and further reduces the problem of straw end bending leading to insertion failure when the straw is inserted into the nozzle bottle mouth interface placed on the limiting mold 17 above the displacement block 26, thus improving the product yield.

[0065] When displacement block 232 is reset, during this process, under the elastic release of the contact spring 236, limit plate 235 drives displacement rack 237 to move towards limit block 243, thereby causing transmission gear 239 to rotate in the opposite direction. Under the action of transmission belt 242, the two rotating rods 238 rotate in the opposite direction, causing cutting block 241 to move away from the middle of rotating rod 238 under the action of guide thread groove 240, thereby resetting cutting block 241.

[0066] like Figure 7 , Figure 8 and Figure 12 As shown, the shape formed by the clamping block 217 and the clamping block 223 after insertion in this embodiment matches the shape of the straw and is on the same axis as the limiting block 243.

[0067] Specifically, the shape formed by the insertion of clamping block 217 and clamping block 223 matches the shape of the straw and is on the same axis as limiting block 243, thereby clamping the straw and moving it to complete the assembly and feeding.

[0068] Example 2

[0069] like Figures 2 to 16 As shown, compared with Embodiment 1, another embodiment of the present invention is as follows:

[0070] like Figure 2 and Figure 4 As shown, in this embodiment, the top of both ends of the limiting block 23 is fixedly connected to a fixing plate 31. Two moving gear rods 32 are rotatably connected to the end of the fixing plate 31 away from the limiting block 23. The two moving gear rods 32 mesh with each other. A micro motor is externally connected to one of the moving gear rods 32. A clamping plate 33 is fixedly connected to the top of the moving gear rod 32. The clamping plates 33 on the two moving gear rods 32 are symmetrically arranged. A displacement groove 34 is opened at the end of the clamping plate 33 away from the moving gear rod 32. A limiting plate 35 is slidably connected in the displacement groove 34. A contact block 36 is fixedly connected to the side of the limiting plate 35 near the middle of the limiting block 23. A compression spring 37 is fixedly connected between the other side of the limiting plate 35 and the inner wall of the displacement groove 34.

[0071] Specifically, during the downward movement of displacement block 26, in the initial state, the two clamping plates 33 are set parallel to one end of the limiting block 23. At this time, a micro motor connected to a motion gear rod 32 is started, and its output end drives the motion gear rod 32 to rotate 90 degrees toward the direction closer to displacement block 26. Then, through the meshing between the two motion gear rods 32, they move relative to each other, thereby causing the clamping plate 33 to rotate together with the motion gear rod 32 it is on, so that the clamping plate 33 rotates 90 degrees around the motion gear rod 32 as the axis and moves toward the direction closer to the middle of displacement block 26.

[0072] When the nozzle core of the nozzle bottle mouth interface is inserted into the limiting mold 17 on the displacement block 26, due to the rotation of the moving gear rod 32, the two clamping plates 33 are attached to the middle of the displacement block 26, and the contact block 36 on them abuts against the suction tube, and the contact block 36 is moved towards the bottom of the displacement groove 34, thereby driving the limiting plate 2 35 to move together with the contact block 36 and elastically compress the compression spring 37. At this time, the two contact blocks 36 are not in direct contact, thus detecting that the suction tube is inserted into the nozzle core of the nozzle bottle mouth interface.

[0073] Then, the micro motor rotates in the opposite direction, thereby resetting the clamping plate 33. During this process, the contact block 36 no longer contacts the suction tube. Under the elastic release of the compression spring 37, the limiting plate 35 and its fixed contact block 36 are reset.

[0074] When the nozzle bottle mouth interface of the nozzle placed on the limiting mold 17 on the displacement block 26 is not connected to the suction tube, the suction tube, which fails to be connected due to bending, deforms at the limiting block 243 and gets stuck at the connection between the limiting block 243 and the guide groove 215. When the displacement block 26 abuts against the contact plate 25, the suction tube is cut off. At this time, after the clamping plate 33 rotates 90 degrees, the two clamping plates 33 are in contact. When the contact block 36 on them directly abuts, the rotating gear 12 stops rotating. After the electric telescopic rod 12 is fully retracted, the electric telescopic rod 12 stops moving, so that the assembly equipment is in a stopped state.

[0075] After the failed insertion of the straw is cleaned up, the motion gear rod 32 rotates in the opposite direction. The specific steps are the same as above, so that the clamping plate 33 is reset. The controller controls the extension and retraction of the electric telescopic rod 22 to insert the straw again. When the electric telescopic rod 22 retracts, the clamping plate 33 is closed again. At this time, the contact block 36 abuts against the straw. When the electric telescopic rod 22 is fully retracted, the rotating gear 12 is started again to make the assembly equipment run normally.

[0076] This invention detects whether the nozzle core of the nozzle bottle mouth interface placed on the limiting mold 17 above the displacement block 26 is successfully inserted into the straw by checking whether the two contact blocks 36 are in direct contact. This avoids an increase in defective products caused by unsuccessful straw insertion and further prevents the straw from blocking the subsequent insertion of the nozzle core into the nozzle bottle mouth interface, thus preventing insertion failure.

[0077] like Figure 15 and Figure 16 As shown, in this embodiment, a collection groove 411 is provided at the center of the top of the displacement block 26. A contraction groove 41 is provided on the top surface of the displacement block 26 near the limiting block 243. An electric telescopic rod 42 is fixedly connected inside the contraction groove 41. A displacement plate 43 is fixedly connected to the top of the electric telescopic rod 42. A fixing plate 44 is symmetrically fixedly connected to the top surface of the displacement plate 43 near the collection groove 411. A rotating shaft 45 is rotatably connected between the fixing plates 44. A micro motor is externally connected to one end of the rotating shaft 45. The surface of the rotating shaft 45 is fixedly... A rotating plate 46 is fixedly connected, and a displacement groove 47 is opened inside the rotating plate 46. A rotating gear 48 is rotatably connected to the middle of the displacement groove 47. A micro motor is externally connected to the rotating gear 48. A displacement rack 49 is symmetrically slidably connected inside the displacement groove 47. The two ends of the two displacement racks 49 away from the rotating gear 48 are fixedly connected to clamping plates 410. The shape of the end of the clamping plate 410 near the limiting block 243 matches the shape of the limiting block 243. The two shrinkage grooves 41 and their internal structures are symmetrically arranged about the collection groove 411.

[0078] Specifically, when the two contact blocks 36 are directly in contact, the controller stops the assembly equipment and controls the electric telescopic rod 42 to extend, causing the electric telescopic rod 42 to move the displacement plate 43 upward until the electric telescopic rod 42 extends to its maximum distance. At this time, the displacement plate 43 is at the top of the shrinkage groove 41 and in contact with the surface of the displacement block 26. At this time, the micro motor on the rotating gear 48 is driven, and the output end of the micro motor drives the rotating gear 48 to rotate, causing the displacement rack 49 to move towards the center of the rotating gear 48. This causes the clamping plate 410 fixed on the displacement rack 49 to move towards the center of the limiting block 243, thereby clamping the deformed and stuck suction tube inside the limiting block 243. Therefore, at this time, the displacement block 26 and the micro motor are in contact with the displacement plate 410. When the contact plate 25 contacts, the straw is cut off. At this time, the micro motor on the drive shaft 45 is driven, which causes the drive shaft 45 to rotate 180 degrees toward the collection tank 411. This causes the drive plate 46 to rotate with the drive shaft 45, so that the deformed straw held between the clamping plates 410 is above the collection tank 411. At this time, the drive gear 2 rotates, which resets the displacement rack 2 49, and resets the clamping plates 410. The clamping plates 410 move away from the center of the drive gear 2 48, causing the deformed straw held between the clamping plates 410 to fall into the collection tank 411. At this time, the drive shaft 45 is reversed and rotated 180 degrees to reset the drive shaft 45 and the drive plate 46. At this time, the control electric telescopic rod 2 42 is retracted, so that the device on the displacement plate 2 43 retracts into the retraction tank 2 41.

[0079] This invention uses the opposing movement of clamping plates 410 to clamp the straw that has deformed and blocked the insertion channel within the limiting block 243. Under the rotation of the rotating shaft 45, the rotating plate 46 drives the clamping plates 410 on it to rotate together, so that the straw held by the clamping plates 410 is above the collection groove 411. This clears the straw that has deformed and blocked the insertion channel within the limiting block 243 after failed insertion, keeping the insertion channel of the straw unobstructed. At the same time, when the clamping plates 410 reset, the straw held on the clamping plates 410 falls into the collection groove 411, thereby collecting the failed insertion straws, maintaining a clean working environment. Furthermore, the collected failed insertion straws can be recycled, reducing production costs.

[0080] like Figure 2 and Figure 3 As shown, in this embodiment, the top two ends of the limiting block 23 and the support platform 18 near the clamping plate 33 are provided with sliding grooves. When the clamping plate 410 is in contact, the contact surface is on the same axis as the limiting block 243. The collecting groove 411 is located within the movement trajectory of the rotating plate 46.

[0081] Specifically, grooves are provided at both ends of the top of the limiting block 23 and on the support platform 18 near the clamping plate 33, so that the clamping plate 33 will not be blocked by the limiting block 23 and the support platform 18 near the clamping plate 33 during movement; when the clamping plate 410 abuts, the contact surface is on the same axis as the limiting block 243, so that the clamping plate 410 can clamp the straw in the limiting block 243; the collection groove 411 is located within the movement trajectory of the rotating plate 46, so that when the rotating shaft 45 rotates 180 degrees, the deformed straw clamped between the collection grooves 411 in the rotating plate 46 can fall into the collection groove 411 and be collected by the collection groove 411.

[0082] Working principle:

[0083] First, the spray core with the nozzle bottle mouth interface is aligned with the sealing ring, allowing the sealing ring to snap into the nozzle bottle mouth interface. Then, the mechanical gripper 19 places it into the limiting mold 17 on the pressing plate 16. At this time, the unidirectional motor connected to the rotating gear 12 is started. The rotation of the output shaft of the unidirectional motor drives the rotating gear 12 to rotate, which in turn drives the transmission gear 15 to rotate, thereby driving the rotating sleeve 14 to rotate. The pressing plate 16 rotates with the rotating sleeve 14, which in turn drives the limiting mold 17 on the pressing plate 16 to rotate synchronously with the pressing plate 16. Initially, the number of limiting molds 17 is the same as the number of teeth of the transmission gear 15. The pressing device 111 on the fixing plate 110 is located directly above one of the limiting molds 17, and the pressing device 111 and the limiting mold 17 are on the same vertical line. When the rotating gear 12 rotates... As mentioned above, when the limiting mold 17 rotates, the one limiting mold 17 after rotation is located below the pressing device 111. At this time, the pressing device 111 is activated to press, thereby making the sealing ring completely embedded in the top of the nozzle bottle mouth interface, thus sealing the connection between the nozzle bottle mouth interface and the spray core. Then, the rotating gear 12 continues to rotate one revolution, so that the sealed nozzle bottle mouth interface after the sealing ring is assembled moves together with the limiting mold 17. At this time, the nozzle cover is placed above the spray core in the nozzle bottle mouth interface located on the movement trajectory of the mechanical gripper 19, and is pressed by the pressing device 111 to make the inside of the nozzle cover insert into the top of the spray core. Subsequently, the rotating gear 12 continues to rotate one revolution, so that the limiting mold 17 is displaced, and the assembled nozzle bottle mouth interface is fixed on the limiting mold 17 by the pressing device 111.

[0084] During the insertion of the straw, the perfume nozzle assembly to be assembled with the straw on the limiting mold 17 is located above the displacement block 26. It is fixed to the limiting mold 17 by the pressing device 111. Then, the electric telescopic rod 22 is activated, causing the displacement block 26 to move towards the limiting mold 17 within the sliding groove 24 until it contacts the limiting mold 17. Initially, the abutting rack 213 at the top of the displacement block 26 protrudes from the top of the displacement block 26. At this point, the limiting block 243 is inserted into the limiting mold 17. During this process, the abutting rack 213 at the top of the displacement block 26 contacts the limiting mold 17, causing the abutting rack 213 to move towards the limiting mold 17. The guide gear rod 28, which is composed of a guide gear and a rotating shaft, moves towards the bottom of the displacement block 26. Under the action of the guide groove 29, the guide gear rod 28 at the top of the displacement block 26 is no longer fixed. At the same time, a groove is formed between the rotating shaft and the guide gear. Because the guide gear on the guide gear rod 28 rotates between the inner walls of the displacement groove 27, the abutting rack 213 at the top of the displacement block 26 moves, causing the guide gear on the guide gear rod 28 at the top of the displacement block 26 to rotate. This, in turn, causes the transmission rack 214 to move upward. The rotation of the guide gear on the guide gear rod 28 at the bottom of the displacement block 26 then causes the abutting rack 213 meshing with it to move downward.

[0085] During the clockwise rotation of the guide gear rod 28 at the top of the displacement block 26, the inner wall of the groove in the guide gear on the guide gear rod 28 abuts against the abutment plate 211, causing the abutment plate 211 to rotate around the fixed rod 210 and compress the return spring 212, so that the abutment plate 211 is retracted into the groove in the rotating shaft rod until the inner wall of the groove of the guide groove 29 in the guide gear passes through the abutment plate 211. At this time, the abutment plate 211 enters the groove of the guide groove 29 in the next guide gear. At this time, the return spring 212 is released elastically to reset the abutment plate 211. This process is repeated to keep the rotating shaft rod on the guide gear rod 28 stationary.

[0086] When the electric telescopic rod 22 retracts, the abutting rack 213 at the top of the displacement block 26 retracts into the displacement groove 27 when the top of the displacement block 26 abuts against the limiting mold 17. Under the action of the guide gear rod 28 and the transmission rack 214, the abutting rack 213 at the bottom of the displacement block 26 extends. During the downward movement of the displacement block 26, when the abutting rack 213 at the bottom of the displacement block 26 abuts against the abutting plate 25, the bottom abutting rack 213 moves upward and drives the bottom guide gear rod 28 to rotate, causing the transmission rack 214 to move downward, thereby driving the guide gear on the top guide gear rod 28 to rotate, and thus driving the top abutting plate 25 to rotate. As rack 213 moves upward and returns to its initial position, during the process of the guide gear on the top guide gear rod 28 driving the top abutting rack 213 to move, as mentioned above, the guide gear rotates in the opposite direction at this time. The inner wall of the groove in the guide gear abuts against the second abutting plate 211, causing the second abutting plate 211 to rotate around the fixed rod 210 as the axis and elastically stretch the first return spring 212. This causes the second abutting plate 211 to abut against the inner wall of the groove in the rotating shaft rod, preventing the inner wall of the groove in the guide gear from being stuck by the second abutting plate 211. This causes the guide gear to be relatively fixed to the rotating shaft rod, thereby driving the rotating shaft rod on the guide gear rod 28 located at the top of the displacement block 26 to rotate counterclockwise.

[0087] During the upward movement of the transmission rack 214, it drives the displacement block 216 fixed to it to move together, causing the displacement block 216 to slide in the guide groove 215. At this time, the clamping block 217 and the clamping block 223 are inserted into each other. As the displacement block 216 moves, it drives the clamping block 217 sliding in it to move together, causing the clamping block 223 to move together with the clamping block 217. Through the fixation of the clamping block 223 and the moving rod 221, the movement of the clamping block 223 drives the moving rod 221 to move together, causing the moving rod 221 to slide in the telescopic groove 220 and elastically compress the telescopic spring 222, thereby driving the clamping block 217 and the clamping block 223 to move together. The straw held between blocks 223 moves toward the limiting mold 17 until the wedge block 218 at the top of the clamping block 217 abuts against the wedge block 219 at the top of the guide groove 215. At this time, the straw passes through the limiting block 243 and is inserted into the nozzle bottle mouth interface on the limiting mold 17 above it. At the same time, the abutment between the wedge block 218 and the wedge block 219 causes the clamping block 217 to slide away from the clamping block 223 in the movement groove 246. Then the clamping block 217 and the clamping block 223 no longer clamp the straw, causing the telescopic spring 222 to release elastically, thereby causing the movement rod 221 and the clamping block 223 to return to the initial position.

[0088] When the electric telescopic rod 22 retracts, the displacement block 26 moves downward, which in turn drives the clamping block 217 to move downward through the downward displacement of the transmission rack 214 until the displacement block 26 contacts the contact plate 25. At this point, the clamping block 217 returns to its initial position. During this process, the wedge block 218 at the bottom of the clamping block 217 contacts the wedge block 219 at the bottom of the guide groove 215, causing the clamping block 217 to move towards the clamping block 223 and engage with it. This allows the clamping block 217 and the clamping block 223 to clamp the straw between them, thus fixing the straw in place.

[0089] When the guide gear rod 28 at the top of displacement block 26 rotates, it drives the transmission bevel gear rod 226 to rotate as well. This causes the rotating column 227 to rotate along with the transmission bevel gear rod 226, and the guide groove 228 to shift with the rotation of the rotating column 227. Consequently, the guide rod 231 moves towards the guide gear rod 28 according to the shape of the guide groove 228. This causes displacement block 229 to move along with the guide rod 231 and elastically compress the reset spring 230. The movement of displacement block 229 then causes displacement block 232 to shift towards the limit block 243 within the cutting groove 244. This causes displacement plate 233 to move along with displacement block 232 until the rotating column 227 rotates one revolution. At this point, under the elastic release of the reset spring 230 and the guiding action of the guide groove 228, the guide rod 231 and displacement block 229 return to their initial positions, thereby resetting displacement block 232 and the displacement plate 233 fixed on it.

[0090] As the displacement plate 233 moves towards the limiting block 243 within the cutting groove 244, when the displacement rack 237 contacts the inner wall of the cutting groove 244, the displacement plate 233 continues to move, causing the displacement rack 237 to slide towards the displacement block 232 within the contraction groove 234. This, in turn, causes the limiting plate 235 to move along with it and elastically compress the contact spring 236. During this process, because the displacement rack 237 meshes with the transmission gear 239, it drives the rotation away from the displacement block 232. The rod 238 rotates, and through the transmission belt 242 on the transmission wheel 247 fixed on the surface of the rotating rod 238, the other rotating rod 238 rotates together. This causes the cutting block 241 to move closer to the middle of the rotating rod 238 under the guidance of the guide thread groove 240, so that the two cutting blocks 241 move towards each other until the displacement rack 237 is completely retracted into the shrinkage groove 234. At this time, the two cutting blocks 241 collide, thereby cutting off the suction tube which is in the same vertical plane as the middle of the rotating rod 238.

[0091] When displacement block 232 is reset, during this process, under the elastic release of the contact spring 236, limit plate 235 drives displacement rack 237 to move towards limit block 243, thereby causing transmission gear 239 to rotate in the opposite direction. Under the action of transmission belt 242, the two rotating rods 238 rotate in the opposite direction, causing cutting block 241 to move away from the middle of rotating rod 238 under the action of guide thread groove 240, thereby resetting cutting block 241.

[0092] During the downward movement of displacement block 26, in the initial state, the two clamping plates 33 are set parallel to one end of the limiting block 23. At this time, a micro motor connected to a motion gear rod 32 is started, and its output end drives the motion gear rod 32 to rotate 90 degrees toward the direction closer to displacement block 26. Then, through the meshing between the two motion gear rods 32, they move relative to each other, and the clamping plate 33 rotates together with the motion gear rod 32 it is on, so that the clamping plate 33 rotates 90 degrees around the motion gear rod 32 as the axis and moves toward the middle of displacement block 26.

[0093] When the nozzle core of the nozzle bottle mouth interface is inserted into the limiting mold 17 on the displacement block 26, due to the rotation of the moving gear rod 32, the two clamping plates 33 are attached to the middle of the displacement block 26, and the contact block 36 on them abuts against the suction tube, and the contact block 36 is moved towards the bottom of the displacement groove 34, thereby driving the limiting plate 2 35 to move together with the contact block 36 and elastically compress the compression spring 37. At this time, the two contact blocks 36 are not in direct contact, thus detecting that the suction tube is inserted into the nozzle core of the nozzle bottle mouth interface.

[0094] Then, the micro motor rotates in the opposite direction, thereby resetting the clamping plate 33. During this process, the contact block 36 no longer contacts the suction tube. Under the elastic release of the compression spring 37, the limiting plate 35 and its fixed contact block 36 are reset.

[0095] When the nozzle bottle mouth interface of the nozzle placed on the limiting mold 17 on the displacement block 26 is not connected to the suction tube, the suction tube, which fails to be connected due to bending, deforms at the limiting block 243 and gets stuck at the connection between the limiting block 243 and the guide groove 215. When the displacement block 26 abuts against the contact plate 25, the suction tube is cut off. At this time, after the clamping plate 33 rotates 90 degrees, the two clamping plates 33 are in contact. When the contact block 36 on them directly abuts, the rotating gear 12 stops rotating. After the electric telescopic rod 12 is fully retracted, the electric telescopic rod 12 stops moving, so that the assembly equipment is in a stopped state.

[0096] After the failed insertion of the straw is cleaned up, the motion gear rod 32 rotates in the opposite direction. The specific steps are the same as above, so that the clamping plate 33 is reset. The controller controls the extension and retraction of the electric telescopic rod 22 to insert the straw again. When the electric telescopic rod 22 retracts, the clamping plate 33 is closed again. At this time, the contact block 36 abuts against the straw. When the electric telescopic rod 22 is fully retracted, the rotating gear 12 is started again to make the assembly equipment run normally.

[0097] When the two contact blocks 36 are directly in contact, the controller stops the assembly equipment and controls the electric telescopic rod 42 to extend, causing the electric telescopic rod 42 to move the displacement plate 43 upward until the electric telescopic rod 42 extends to its maximum distance. At this point, the displacement plate 43 is at the top of the shrinkage groove 41 and in contact with the surface of the displacement block 26. At this time, the micro motor on the rotating gear 48 is driven, and the output end of the micro motor drives the rotating gear 48 to rotate, causing the displacement rack 49 to move towards the center of the rotating gear 48. This causes the clamping plate 410 fixed on the displacement rack 49 to move towards the center of the limiting block 243, thereby clamping the deformed and stuck suction tube inside the limiting block 243. Therefore, the displacement block 26 is in contact with the contact plate 46. When plate 25 comes into contact, the straw is cut off. At this time, the micro motor on the rotating shaft 45 is driven, causing the rotating shaft 45 to rotate 180 degrees toward the collection tank 411. This causes the rotating plate 46 to rotate with the rotating shaft 45, so that the deformed straw held between the clamping plates 410 is above the collection tank 411. At this time, the rotating gear 48 rotates in the same direction, causing the displacement rack 49 to reset, which in turn resets the clamping plate 410. The clamping plate 410 moves away from the center of the rotating gear 48, causing the deformed straw held between the clamping plates 410 to fall into the collection tank 411. At this time, the rotating shaft 45 is driven to rotate 180 degrees in the opposite direction to reset the rotating shaft 45 and reset the rotating plate 46. At this time, the electric telescopic rod 42 is controlled to retract, causing the device on the displacement plate 43 to retract into the retraction tank 41.

[0098] At this point, the assembly of the perfume nozzle connector is complete. Then, the rotating gear 12 rotates one more revolution, causing the limiting mold 17 where the assembled perfume nozzle connector is located to continue moving. The mechanical gripper 19 collects the assembled perfume nozzle connector. As the rotating gear 12 moves, there are no more perfume nozzle connector parts to be assembled on the limiting mold 17 until the limiting mold 17 returns to its initial position, and then the assembly continues. This process is repeated.
