Description

Technical Field

[0001] The invention belongs to the technical field of nozzle joint assembly, in particular to an automatic assembly device for a perfume nozzle joint. Background Art

[0002] The automatic assembly equipment for perfume nozzle joints is a kind of equipment used for automatic production and assembly of perfume sprayer joints. Its function is to improve the efficiency of producing perfume nozzle joints, ensure the quality of perfume nozzle joints after assembly, and reduce production costs.

[0003] In the prior art, first, the spray core with the spray bottle mouth interface is connected to the sealing ring so that the sealing ring is stuck in the spray bottle mouth interface, then, it is placed in the limiting mold on the crimping plate by a mechanical clamp, and a crimping device is used to extrude it so that the sealing ring is completely embedded in the top of the spray bottle mouth interface, thereby sealing the connection between the spray bottle mouth interface and the spray core, then, the nozzle cover is placed on the spray core by a mechanical clamp, and extruded so that the inside of the nozzle cover is plugged into the top of the spray core, then, it is fixed on the limiting mold by a crimping device, and the straw is connected to the spray core by a plug-in machine, and the excess straw is cut off at the same time, and finally, the assembled perfume nozzle joint is collected by a mechanical clamp.

[0004] There are still some problems in the actual use of the existing automatic assembly equipment for perfume nozzle joints. During the process of inserting straws, the straw plugging machine in the existing automatic assembly equipment for perfume nozzle joints will roll the straws into round coils when stored. Some straws will be slightly bent after long-term storage, resulting in the top of the straw being unable to fully dock with the bottom interface of the spray core when the straw plugging machine inserts the straws, resulting in plugging failure. The straws that fail to plug are deformed and stuck at the plugging interface of the straw plugging machine, so that when the straw plugging machine continues to insert the straws, normal straws may not be correctly plugged with the bottom of the spray core, thereby affecting the assembly efficiency and quality of the perfume nozzle joint.

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0045] Embodiment 1

[0046] like Figures 1 to 16As shown, an automatic assembly device for a perfume nozzle joint according to an embodiment of the present invention comprises a workbench 1, a movement cavity 11 is provided on the workbench 1, a rotating gear 12 is rotatably connected in the movement cavity 11, a unidirectional motor is externally connected to the rotating gear 12, a support seat 13 is fixedly connected to the middle of the movement cavity 11, a rotating sleeve 14 is rotatably connected between the top lower surface of the support seat 13 and the movement cavity 11, a transmission gear 15 is fixedly connected to the bottom surface of the rotating sleeve 14, the transmission gear 15 is meshed with the rotating gear 12, and the top surface of the rotating sleeve 14 is fixedly connected to the bottom surface of the rotating sleeve 14. A crimping plate 16 is fixedly connected to the surface, and a plurality of limiting molds 17 are fixedly connected to the side walls of the crimping 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 circular array around the rotating sleeve 14. Mechanical clamps 19 are provided on the three support platforms 18. A plurality of fixed plates 110 are provided on the top of the support seat 13, and crimping devices 111 are symmetrically provided on the plurality of fixed plates 110. A plug-in straw assembly is provided on the top near one side of the workbench 1, and the straw plug-in assembly is used to plug the straw into the bottom end of the spray core and cut the straw of a predetermined length.

[0047] Specifically, there are still some problems in the actual use of the existing automatic assembly equipment for perfume nozzle joints. Since the straws will be rolled into round coils when stored, some straws will be slightly bent after long-term storage, resulting in the top of the straw and the bottom interface of the spray core being unable to be fully docked when the straw plug-in machine plugs the straws, resulting in plug-in failure. The straws that fail to plug in are deformed in the limit block 243 of the straw plug-in machine and get stuck in the plug-in interface in the limit block 243, so that when the straw plug-in machine continues to plug in the straws, the normal straws may not be correctly plugged with the bottom of the spray core, thereby affecting the assembly efficiency and quality of the perfume nozzle joint.

[0048] Therefore, the present 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 stuck in the nozzle bottle mouth interface. Then, it is placed in the limiting mold 17 on the crimping disk 16 through the mechanical clamp 19. At this time, the external unidirectional motor on the rotating gear 12 is started, and the rotating gear 12 is driven to rotate by the rotation of the output shaft of the unidirectional motor, so that the rotating gear 12 drives the transmission gear 15 to rotate, and then drives the rotating sleeve 14 to rotate, so that the crimping disk 16 rotates with the rotating sleeve 14, and then drives the limiting mold 17 on the crimping disk 16. The position mold 17 rotates synchronously with the crimping plate 16. Initially, the number of the limit molds 17 set is the same as the number of teeth of the transmission gear 15. The crimping device 111 on the fixed plate 110 is located directly above a limit mold 17, and the crimping device 111 and the limit mold 17 are on the same vertical line. When the rotating gear 12 rotates one circle, it can be seen from the above that the limit mold 17 rotates. At this time, a limit mold 17 after rotation is located below the crimping device 111. At this time, the crimping device 111 is started to squeeze the crimping device 111, so that the sealing ring is completely embedded in the spray bottle. The top of the nozzle interface is moved to seal the connection between the nozzle bottle interface and the spray core, and then the gear 12 is rotated for one more circle to move the sealed nozzle bottle interface after the sealing ring is assembled together with the limiting mold 17. At this time, the nozzle cover is placed on the spray core in the nozzle bottle interface located on the movement track of the mechanical clamp 19 through the mechanical clamp 19, and is squeezed through the crimping device 111 to make the inside of the nozzle cover plugged with the top of the spray core, and then the gear 12 is rotated for one more circle to displace the limiting mold 17, and the assembled nozzle bottle interface is crimped through the crimping device 111. The stopper 17 is fixed on the limit mold 17. At this time, the straw is connected to the spray core through the straw plug-in assembly, and the excess straw is cut off, thereby completing the assembly of the perfume nozzle joint. At this time, the rotating gear 12 continues to rotate one circle, so that the limit mold 17 where the assembled perfume nozzle joint is located continues to move, and the assembled perfume nozzle joint is collected by the mechanical clamp 19. With the movement of the rotating gear 12, the parts of the perfume nozzle joint that need to be assembled are no longer placed on the limit mold 17 until the limit mold 17 returns to the initial position, and then continues to assemble, and so on.

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

[0050] Specifically, the shape of the rotating gear 12 is a two-tooth gear. Initially, the number of the limiting molds 17 set is the same as the number of teeth of the transmission gear 15, so that when the rotating gear 12 rotates one circle, the transmission gear 15 rotates a distance of two teeth, thereby controlling the displacement distance of the limiting mold 17 thereon; the crimping device 111 is located above the limiting mold 17. Initially, the crimping device 111 and the limiting mold 17 are in the same vertical line, so that the crimping device 111 can accurately press down the parts of the perfume nozzle connector on the limiting mold 17; the limiting mold 17 is located on the motion trajectory of the mechanical clamp 19, so that the mechanical clamp 19 places the parts of the perfume nozzle connector to be assembled on the limiting mold 17.

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

[0052] The displacement block 1 26 is symmetrically provided with a displacement groove 1 27, and the two displacement grooves 1 27 are both slidably connected with a conflicting rack 213. The displacement block 1 26 is provided with a displacement groove 245, and the displacement groove 245 is slidably connected with a transmission rack 214. The displacement groove 245 is connected with the two displacement grooves 1 27, and the connection between the displacement groove 245 and the two displacement grooves 1 27 is rotatably connected with a guide gear rod 28, and the guide gear rod 28 is composed of a guide gear and a rotating shaft rod. The guide gear on the guide gear rod 28 rotates between the inner walls of the displacement groove 1 27, and the transmission rack 214 is meshed with the guide gears on the two guide gear rods 28, and each conflicting rack 213 is meshed with a guide gear on a guide gear rod 28;

[0053] A rotation groove 224 is provided in the displacement block 1 26, and the rotation groove 224 is connected with the displacement groove 245. The rotating shaft rod on the guide gear rod 28 located at the top of the displacement block 1 26 rotates between the rotation groove 224 and the displacement groove 245, and a guide groove 29 is provided between the rotating shaft rod on the guide gear rod 28 located at the top of the displacement block 1 26 and the guide gear, so that the rotating shaft rod on the guide gear rod 28 located at the top of the displacement block 1 26 and the guide gear are no longer fixed, and a groove is formed between the rotating shaft rod and the guide gear, and a fixing rod 210 is fixedly connected between the inner walls of the groove in the rotating shaft rod, and a contact plate 211 is rotatably connected to the surface of the fixing rod 210, and the contact plate 211 rotates in the guide groove 1 29, and a return spring 212 is fixedly connected between the side of the contact plate 211 close to the middle of the guide gear rod 28 and the inner wall of the guide groove 1 29.

[0054] Specifically, during the process of inserting the straw, the perfume spray head assembly on the limiting mold 17 that needs to be assembled with the straw is located above the displacement block 26, and is fixed to the limiting mold 17 by the crimping device 111. At this time, the electric telescopic rod 22 is started, and the displacement block 26 is driven to move in the sliding groove 24 toward the direction close to the limiting mold 17 through the extension of the electric telescopic rod 22, until the displacement block 26 conflicts with the limiting mold 17. In the initial state, the part of the conflicting rack 213 at the top of the displacement block 26 is exposed from the top of the displacement block 26. At this time, the limiting block 243 is inserted into the limiting mold 17. During this process, the conflicting rack 213 at the top of the displacement block 26 conflicts with the limiting mold 17, so that the conflicting rack 213 Move toward the direction close to the bottom of the displacement block 26, the guide gear rod 28 is composed of a guide gear and a rotating shaft rod, and the guide gear rod 28 located at the top of the displacement block 26 is no longer fixed under the action of the guide groove 29, and a groove is formed between the rotating shaft rod 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 guide gear on the guide gear rod 28 located at the top of the displacement block 26 is driven to rotate when the interference rack 213 at the top of the displacement block 26 is displaced, thereby driving the transmission rack 214 to move upward, so that the guide gear on the guide gear rod 28 located at the bottom of the displacement block 26 rotates, thereby driving the interference rack 213 meshed with it to move downward;

[0055] During the clockwise rotation of the guide gear rod 28 at the top of the displacement block 1 26, the inner wall of the groove in the guide gear on the guide gear rod 28 abuts against the second abutment plate 211, and the second abutment plate 211 rotates around the fixed rod 210 and compresses the return spring 1 212, so that the second abutment plate 211 is retracted into the groove in the shaft rod until the inner wall of the groove of the guide groove 1 29 in the guide gear passes through the return spring 1 211, and the return spring 1 212 is elastically released to reset the second abutment plate 211, and this is repeated to make the shaft rod on the guide gear rod 28 stationary;

[0056] When the electric telescopic rod 22 is retracted, the top of the displacement block 26 contacts the limiting mold 17, and the contact rack 213 at the top of the displacement block 26 is retracted into the displacement groove 27. Under the action of the guide gear rod 28 and the transmission rack 214, the contact rack 213 at the bottom of the displacement block 26 extends. In the process of the displacement block 26 moving downward, when the contact rack 213 at the bottom of the displacement block 26 contacts the contact plate 25, in this process, the bottom contact rack 213 moves upward and drives the bottom guide gear rod 28 to rotate, so that the transmission rack 214 moves downward, thereby driving the guide gear on the top guide gear rod 28 to rotate, thereby driving the top contact rack 214 to rotate. The rack 213 moves upward to return to its initial position. In the process of the guide gear on the top guide gear rod 28 driving the top interference rack 213 to move, it can be seen from the above that the guide gear rotates in the opposite direction at this time, and the inner wall of the groove in the guide gear contacts the interference plate 211, so that the interference plate 211 rotates around the fixed rod 210 as the axis and elastically stretches the return spring 1 212, thereby causing the interference plate 211 to contact the inner wall of the groove in the shaft rod, so that the inner wall of the groove in the guide gear cannot be stuck by the interference plate 211, thereby fixing the guide gear and the shaft rod relatively, thereby driving the shaft rod on the guide gear rod 28 located at the top of the displacement block 1 26 to rotate counterclockwise.

[0057] like Figures 7 to 11As shown, in this embodiment, the displacement block 1 26 is provided with a guide groove 215, and the guide groove 215 is connected to the limit block 243, and the guide groove 215 is connected to the displacement groove 245. The top of the transmission rack 214 is fixedly connected with a displacement block 216 on the side away from the guide gear rod 28, and the displacement block 216 slides in the guide groove 215. The displacement block 216 is provided with a motion groove 246, and the motion groove 246 is slidably connected with a clamping block 217. The shape of the motion groove 246 matches the shape of the clamping block 217. The top surface and the bottom surface of the clamping block 217 are fixedly connected with a wedge block 218. The guide groove 2 The top and bottom surfaces of 215 are fixedly connected with wedge blocks 219, and the wedge blocks 219 are on the movement trajectory of wedge blocks 1 218. A clamping block 223 is slidably connected in the guide groove 215, and the clamping block 223 is located on the side of the clamping block 217 away from the transmission rack 214. The clamping block 1 217 is inserted into the clamping block 223. A telescopic groove 220 is provided at the bottom of the guide groove 215, and 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, and a telescopic spring 222 is fixedly connected between the upper surface of the bottom end of the moving rod 221 and the top inner wall of the telescopic groove 220.

[0058] Specifically, during the upward movement of the transmission rack 214, the displacement block 216 fixed thereto is driven to move together, so that the displacement block 216 slides in the guide groove 215. At this time, the clamping block 1 217 is plugged with the clamping block 223, and then during the displacement of the displacement block 216, the clamping block 1 217 sliding therein is driven to move together, so that the clamping block 223 moves together with the clamping block 1 217. By fixing the clamping block 223 and the moving rod 221, the moving rod 221 is driven to move together during the movement of the clamping block 223, so that the moving rod 221 slides in the telescopic groove 220 and elastically compresses the telescopic spring 222, thereby driving the clamping block 1 217 and the moving rod 221. The straw clamped between the clamping blocks 223 moves toward the direction close to the limiting mold 17 until the wedge block 218 at the top of the clamping block 217 contacts 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 plugged into the spray core of the nozzle bottle mouth interface on the limiting mold 17 above it. At the same time, the contact between the wedge block 218 and the wedge block 219 causes the clamping block 217 to slide in the moving groove 246 in the direction away from the clamping block 223, so that the clamping block 217 and the clamping block 223 no longer clamp the straw, so that the telescopic spring 222 is elastically released, and the moving rod 221 and the clamping block 223 return to the initial position.

[0059] When the electric telescopic rod 22 contracts, the displacement block 26 moves downward, and the downward displacement of the transmission rack 214 drives the clamping block 217 to move downward until the displacement block 26 contacts the contact plate 25, and the clamping block 217 returns to the 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, so that the clamping block 217 moves toward the direction close to the clamping block 223 and plugs into the clamping block 223, so that the clamping block 217 and the clamping block 223 clamp the straw therebetween, so that the straw is fixed.

[0060] like Figure 5 , Figure 6 and Fig.12 As shown, in this embodiment, a rotating bevel gear 225 is fixedly connected to the surface of the rotating shaft rod on the guide gear rod 28 in the rotating groove 224, a transmission bevel gear rod 226 is rotatably connected in the rotating groove 224, the transmission bevel gear rod 226 is meshed 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 3 228 is provided on the surface of the rotating column 227, a displacement block 3 229 is slidably connected in the rotating groove 224, the displacement block 3 229 is located above the rotating column 227, and a side of the displacement block 3 229 close to the guide gear rod 28 is between 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 3 229, and the guide rod 231 slides in the guide groove 3 228. A cutting groove 244 is opened on the displacement block 1 26, and the cutting groove 244 is connected with the guide groove 215 and the rotating groove 224. A displacement block 4 232 is slidably connected in the cutting groove 244, and one side of the displacement block 4 232 is fixedly connected to the displacement block 3 229, and a displacement plate 1 233 is fixedly connected to the side of the displacement block 4 232 close to the limit block 243, and the displacement plate 1 233 slides in the connection between the cutting groove 244 and the guide groove 2 215.

[0061] Specifically, when the guide gear rod 28 at the top of the displacement block 1 26 rotates, it drives the transmission bevel gear rod 226 to rotate together, so that the rotating column 227 rotates together with the transmission bevel gear rod 226, and the guide groove three 228 is displaced along with the rotation of the rotating column 227, so that the guide rod 231 moves in the direction close to the guide gear rod 28 along with the shape of the guide groove three 228, thereby driving the displacement block three 229 to move together with the guide rod 231 and elastically compress the return spring two 230, and then through the movement of the displacement block three 229, the displacement block four 232 is driven to move in the cutting groove 244 in the direction close to the limit block two 243, and then the displacement plate one 233 is driven to move together with the displacement block four 232 until the rotating column 227 rotates one circle. At this time, under the elastic release of the return spring two 230 and the guiding action of the guide groove three 228, the guide rod 231 and the displacement block three 229 return to the initial position, thereby driving the displacement block four 232 and the displacement plate one 233 fixed thereon to reset.

[0062] like Figure 12 to Figure 14 As shown, in this embodiment, the displacement plate 233 described in the present embodiment is symmetrically provided with a contraction groove 234, and a limit plate 235 is slidably connected in the contraction groove 234. A contact spring 236 is symmetrically fixedly connected between the limit plate 235 and the contraction groove 234. A displacement rack 237 is fixedly connected to the side of the limit plate 235 away from the contact spring 236. The displacement rack 237 is slidably connected in the contraction groove 234. Two rotating rods 238 are rotatably connected to the middle part of the displacement plate 233, and the surfaces of the two rotating rods 238 are symmetrical. A guide thread groove 240 is provided, and cutting blocks 241 are threadedly connected to the surfaces of the two guide thread grooves 240. Transmission gears 239 are fixedly connected to the two ends of the rotating rod 238 away from the displacement plate 233. The transmission gears 239 are meshed with the displacement rack 237. Transmission wheels 247 are fixedly connected to the surfaces of the two rotating rods 238. A transmission belt 242 is connected between the two transmission wheels 247. The transmission belt 242 is symmetrically connected to the two ends of the two rotating rods 238. The structures in the displacement block 26 are symmetrically arranged.

[0063] Specifically, during the process of displacement plate 1 233 moving in the cutting groove 244 in the direction close to limit block 243, when displacement rack 1 237 contacts the inner wall of cutting groove 244, displacement plate 1 233 continues to move, causing displacement rack 1 237 to slide in the contraction groove 1 234 in the direction close to displacement block 4 232, thereby driving limit plate 1 235 to move along with it and elastically compress contact spring 236. In this process, displacement rack 1 237 meshes with transmission gear 2 239, thereby driving the displacement block 4 232 to move away from the displacement block 4 232. The rotating rod 238 rotates, and the transmission belt 242 on the transmission wheel 247 fixed on the surface of the rotating rod 238 drives the other rotating rod 238 to rotate together, so that the cutting block 241 is driven by the guide thread groove 240 to approach the middle of the rotating rod 238, so that the two cutting blocks 241 move toward each other until the displacement rack 1 237 is completely retracted into the retracting groove 1 234. At this time, the two cutting blocks 241 collide with each other, and then the straws in the same vertical plane as the middle of the rotating rod 238 are cut off;

[0064] The present invention cuts the straws by the opposite movement of the cutting blocks 241, thereby preventing the cut straws from bending due to the influence of unidirectional cutting during the cutting process, reducing the problem of bending of the cut straws during the cutting process, and further reducing the problem of failed insertion due to bending of the straw ends when the straws are plugged into the spray core of the nozzle bottle mouth interface placed on the limiting mold 17 above the displacement block 26, thereby improving the yield rate of the product.

[0065] When the displacement block four 232 is reset, during this process, under the action of the elastic release of the resistance spring 236, the limit plate 1 235 drives the displacement rack 1 237 to move towards the direction close to the limit block two 243, thereby causing the transmission gear two 239 to rotate in the opposite direction, and under the action of the transmission belt 242, the two rotating rods 238 rotate in the opposite direction, causing the cutting block 241 to be displaced in the direction away from the middle of the rotating rod 238 under the action of the guide thread groove 240, thereby resetting the cutting block 241.

[0066] like Figure 7 , Figure 8 and Fig.12 As shown, the shape formed by the connection between the clamping block 1 217 and the clamping block 223 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 connection between the clamping block 1 217 and the clamping block 223 matches the shape of the straw and is coaxial with the limiting block 243, thereby clamping the straw and driving its displacement, thereby completing assembly and feeding.

[0068] Embodiment 2

[0069] like Figures 2 to 16 As shown, compared with Example 1, another implementation of the present invention is:

[0070] like Figure 2 and Figure 4 As shown, in this embodiment, a fixing plate 21 is fixedly connected to the top of both ends of the limit block 23, and the end of the fixing plate 21 away from the limit block 23 is rotatably connected to two moving gear rods 32, the two moving gear rods 32 are meshed with each other, and a micro motor is externally connected to one moving gear rod 32, and a clamping plate 33 is fixedly connected to the top of the moving gear rod 32, and the clamping plates 33 on the two moving gear rods 32 are symmetrically arranged, and a displacement groove 34 is provided at one end of the clamping plate 33 away from the moving gear rod 32, and a limiting plate 21 is slidably connected in the displacement groove 34, and a contact block 36 is fixedly connected to one side of the limit plate 21 close to the middle of the limit block 23, and a compression spring 37 is fixedly connected between the other side of the limit plate 21 and the inner wall of the displacement groove 34.

[0071] Specifically, in the process of the displacement block 26 moving downward, in the initial state, the two clamping plates 33 are arranged parallel to one end of the limit block 23, and at this time, a micro motor externally connected to a moving gear rod 32 is started, and the moving gear rod 32 is driven to rotate 90 degrees in the direction close to the displacement block 26 through its output end, and then the two moving gear rods 32 are meshed to make them move relative to each other, so that the clamping plate 33 rotates together with the moving gear rod 32 on which it is located, so that the clamping plate 33 rotates 90 degrees with the moving gear rod 32 as the axis, and moves in the direction close to the middle of the displacement block 26;

[0072] When the spray core of the nozzle bottle mouth interface placed on the limiting mold 17 on the displacement block 1 26 is plugged with a straw, at this time, due to the rotation of the moving gear rod 32, the two clamping plates 33 fit in the direction close to the middle of the displacement block 1 26, and the contact block 36 thereon contacts with the straw, and causes the contact block 36 to move in the direction close to the bottom of the displacement groove 3 34, thereby driving the limiting plate 2 35 to move 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, thereby detecting that the straw is plugged into the spray 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 straw, and the second limit plate 35 and the contact block 36 fixed thereto are reset under the elastic release of the compression spring 37.

[0074] When the spray core of the nozzle bottle mouth interface placed on the limiting mold 17 on the displacement block 1 26 is not connected with a straw, the straw that fails to be connected due to the bending of the straw is deformed at the limiting block 243 and stuck at the connection between the limiting block 243 and the guide groove 215, and the displacement block 1 26 conflicts with the contact plate 1 25, and the straw is cut off. At this time, after the clamping plate 33 rotates 90 degrees, the two clamping plates 33 fit together, and when the contact blocks 36 thereon directly conflict, the rotating gear 12 stops rotating, and after the electric telescopic rod 1 22 is fully retracted, the electric telescopic rod 1 22 stops moving, so that the assembly equipment is in a shutdown state;

[0075] After the failed straws are cleaned, the moving gear rod 32 rotates in the opposite direction, and the specific steps are the same as above, so that the clamping plate 33 is reset, and the electric telescopic rod 22 is controlled by the controller to retract, and the straws are inserted again, and the clamping plate 33 is again fitted when the electric telescopic rod 22 is retracted. At this time, the contact block 36 is in conflict with the straw, and when the electric telescopic rod 22 is completely retracted, the rotating gear 12 is started again to make the assembly equipment operate normally;

[0076] The present invention detects whether the limiting mold 17 above the displacement block 26 and the spray core of the nozzle bottle mouth interface placed thereon are successfully plugged with the straw by whether the two contact blocks 36 are in direct contact, thereby avoiding an increase in defective products caused by unsuccessful insertion of the straw, and further preventing continued insertion from causing the unsuccessful insertion of the straw to block the subsequent insertion of the straw and the spray core of the nozzle bottle mouth interface, resulting in a plugging failure.

[0077] like Fig.15 and Fig.16 As shown, in this embodiment, a collecting groove 411 is provided at the middle of the top of the displacement block 1 26, and a contraction groove 21 is provided on the top surface of the displacement block 1 26 near the limit block 243. An electric telescopic rod 21 is fixedly connected in the contraction groove 21, and a displacement plate 21 is fixedly connected to the top of the electric telescopic rod 21. A fixed plate 31 is symmetrically fixedly connected to the top surface of the displacement plate 21 near the collecting groove 411, and a rotating shaft 45 is rotatably connected between the fixed plates 31. A micro motor is externally connected to one end of the rotating shaft 41, and a surface of the rotating shaft 41 is fixedly connected to the electric telescopic rod 21. A rotating plate 46 is fixedly connected, a displacement groove four 47 is opened inside the rotating plate 46, a rotating gear two 48 is rotatably connected to the middle of the displacement groove four 47, a micro motor is externally connected to the rotating gear two 48, a displacement rack two 49 is symmetrically slidably connected in the displacement groove four 47, two displacement racks two 49 are fixedly connected with a clamping plate 410 at both ends away from the rotating gear two 48, the shape of one end of the clamping plate 410 close to the limit block two 243 matches the shape of the limit block two 243, and the two contraction grooves two 41 and the internal structure thereof are symmetrically arranged about the collecting groove 411.

[0078] Specifically, when the two contact blocks 36 are directly in contact with each other, the controller is used to stop the assembly equipment, and the controller controls the electric telescopic rod 242 to extend, so that the electric telescopic rod 242 drives the displacement plate 243 to move upward until the electric telescopic rod 242 is extended to the maximum distance. At this time, the displacement plate 243 is at the top of the contraction groove 241 and in contact with the surface of the displacement block 1 26. At this time, the micro motor on the rotating gear 248 is driven, and the rotating gear 248 is driven to rotate through the output end of the micro motor, so that the displacement rack 249 moves toward the direction close to the middle of the rotating gear 248, and then drives the clamping plate 410 fixed on the displacement rack 249 to move toward the direction close to the middle of the limit block 243, so as to clamp the deformed and stuck straw in the limit block 243. The abutment plate 25 abuts against the straw, so that the straw is cut off. At this time, the micro-motor on the rotating shaft 45 is driven, so that the rotating shaft 45 rotates 180 degrees in the direction close to the collecting groove 411, and the rotating plate 46 rotates together with the rotating shaft 45, so that the deformed straw clamped between the clamping plates 410 is above the collecting groove 411. At this time, the rotating gear 48 rotates in the direction to reset the displacement rack 49, and then the clamping plate 410 is reset, and the clamping plate 410 moves in the direction away from the middle of the rotating gear 48, so that the deformed straw clamped between the clamping plates 410 falls into the collecting groove 411. At this time, the rotating shaft 45 is driven in the reverse direction to rotate 180 degrees to reset the rotating shaft 45 and the rotating plate 46. At this time, the electric telescopic rod 42 is controlled to shrink, so that the device on the displacement plate 43 shrinks into the shrinkage groove 41;

[0079] The present invention clamps the straws that are deformed and block the plug-in channel in the limit block 243 through the opposite movement of the clamping plates 410, and the rotating plate 46 drives the clamping plate 410 thereon to rotate together under the rotation of the rotating shaft 45, so that the straws clamped by the clamping plates 410 are located above the collecting groove 411, thereby cleaning up the straws that are deformed and block the plug-in channel in the limit block 243 after the plug-in fails, so that the channel for plugging the straws remains unobstructed, and at the same time, when the clamping plates 410 are reset, the straws clamped on the clamping plates 410 fall into the collecting groove 411, thereby collecting the straws that have failed to be plugged in, thereby keeping the working environment clean, and further, the collected straws that have failed to be plugged in can be recycled, thereby reducing the production cost.

[0080] like Figure 2 and Figure 3 As shown, in this embodiment, both ends of the top of the limit block 23 and the support platform 18 close to the clamping plate 33 are provided with sliding grooves, and when the clamping plate 410 is in contact, the contact surface and the limit block 2 243 are on the same axis, and the collecting groove 411 is located within the motion trajectory of the rotating plate 46.

[0081] Specifically, sliding grooves are provided on both ends of the top of the limit block 23 and the support platform 18 close to the clamping plate 33, so that the clamping plate 33 will not be blocked by the limit block 23 and the support platform 18 close to the clamping plate 33 during movement; when the clamping plate 410 contacts, the contact surface is on the same axis as the limit block 243, so that the clamping plate 410 can clamp the straw in the limit block 243; the collecting groove 411 is located in the movement trajectory of the rotating plate 46, so that when the rotating shaft 45 rotates one hundred and eighty degrees, the deformed straw clamped between the collecting grooves 411 in the rotating plate 46 can fall into the collecting groove 411 and then be collected by the collecting groove 411.

[0082] Working principle:

[0083] First, dock the spray core with the nozzle bottle mouth interface with the sealing ring, so that the sealing ring is stuck in the nozzle bottle mouth interface, and then place it in the limiting mold 17 on the crimping disk 16 through the mechanical clamp 19, and then start the external unidirectional motor on the rotating gear 12, and the rotation of the output shaft of the unidirectional motor drives the rotating gear 12 to rotate, so that the rotating gear 12 drives the transmission gear 15 to rotate, and then drives the rotating sleeve 14 to rotate, so that the crimping disk 16 rotates with the rotating sleeve 14, and then drives the limiting mold 17 on the crimping disk 16 to rotate synchronously with the crimping disk 16. Initially, the number of limiting molds 17 set is the same as the number of teeth of the transmission gear 15, and the crimping device 111 on the fixed plate 110 is located directly above a limiting mold 17, and the crimping device 111 and the limiting mold 17 are on the same vertical line. When the rotating gear 12 rotates one When the limit mold 17 is rotated, it can be known from the above that the limit mold 17 rotates. At this time, the rotated limit mold 17 is located under the crimping device 111. At this time, the crimping device 111 is started to squeeze the crimping device 111, so that the sealing ring is 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. Then, the rotating gear 12 continues to rotate one circle, so that the sealed nozzle bottle mouth interface after the sealing ring is assembled moves with the limit 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 clamp 19 here through the mechanical clamp 19, and squeezed through the crimping device 111 to make the inside of the nozzle cover plugged with the top of the spray core. Then, the rotating gear 12 continues to rotate one circle to displace the limit mold 17, and the assembled nozzle bottle mouth interface is fixed on the limit mold 17 through the crimping device 111;

[0084] During the process of inserting the straw, the perfume spray head assembly on the limiting mold 17 that needs to be assembled with the straw is located above the displacement block 26, and is fixed to the limiting mold 17 by the crimping device 111. At this time, the electric telescopic rod 22 is started, and the displacement block 26 is driven to move in the sliding groove 24 toward the direction close to the limiting mold 17 through the extension of the electric telescopic rod 22, until the displacement block 26 conflicts with the limiting mold 17. In the initial state, the part of the conflicting rack 213 at the top of the displacement block 26 is exposed from the top of the displacement block 26. At this time, the limiting block 243 is inserted into the limiting mold 17. During this process, the conflicting rack 213 at the top of the displacement block 26 conflicts with the limiting mold 17, causing the conflicting rack 213 to move toward the limiting mold 17. The guide gear rod 28 is composed of a guide gear and a rotating shaft rod, and the guide gear rod 28 located at the top of the displacement block 26 is no longer fixed under the action of the guide groove 29, and a groove is formed between the rotating shaft rod 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 guide gear on the guide gear rod 28 at the top of the displacement block 26 is driven to rotate when the interference rack 213 at the top of the displacement block 26 is displaced, thereby driving the transmission rack 214 to move upward, so that the guide gear on the guide gear rod 28 at the bottom of the displacement block 26 rotates, thereby driving the interference 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 1 26, the inner wall of the groove in the guide gear on the guide gear rod 28 abuts against the second abutment plate 211, and the second abutment plate 211 rotates around the fixed rod 210 and compresses the return spring 1 212, so that the second abutment plate 211 is retracted into the groove in the shaft rod until the inner wall of the groove of the guide groove 1 29 in the guide gear passes through the return spring 1 211, and the return spring 1 212 is elastically released to reset the second abutment plate 211, and this is repeated to make the shaft rod on the guide gear rod 28 stationary;

[0086] When the electric telescopic rod 22 is retracted, the top of the displacement block 26 contacts the limiting mold 17, and the contact rack 213 at the top of the displacement block 26 is retracted into the displacement groove 27. Under the action of the guide gear rod 28 and the transmission rack 214, the contact rack 213 at the bottom of the displacement block 26 extends. In the process of the displacement block 26 moving downward, when the contact rack 213 at the bottom of the displacement block 26 contacts the contact plate 25, in this process, the bottom contact rack 213 moves upward and drives the bottom guide gear rod 28 to rotate, so that the transmission rack 214 moves downward, thereby driving the guide gear on the top guide gear rod 28 to rotate, thereby driving the top contact rack 214 to rotate. The rack 213 moves upward to return to its initial position. In the process of the guide gear on the top guide gear rod 28 driving the top interference rack 213 to move, it can be seen from the above that the guide gear rotates in the opposite direction at this time, and the inner wall of the groove in the guide gear contacts the interference plate 211, so that the interference plate 211 rotates around the fixed rod 210 as the axis and elastically stretches the return spring 1 212, thereby causing the interference plate 211 to contact the inner wall of the groove in the shaft rod, so that the inner wall of the groove in the guide gear cannot be stuck by the interference plate 211, thereby fixing the guide gear and the shaft rod relatively, thereby driving the shaft rod on the guide gear rod 28 located at the top of the displacement block 1 26 to rotate counterclockwise.

[0087] During the upward movement of the transmission rack 214, the displacement block 216 fixed thereto is driven to move together, so that the displacement block 216 slides in the guide groove 215. At this time, the clamping block 1 217 is plugged with the clamping block 223, and then during the displacement of the displacement block 216, the clamping block 1 217 sliding therein is driven to move together, so that the clamping block 223 moves together with the clamping block 1 217. Through the fixation of the clamping block 223 and the moving rod 221, the moving rod 221 is driven to move together during the movement of the clamping block 223, so that the moving rod 221 slides in the telescopic groove 220 and elastically compresses the telescopic spring 222, thereby driving the clamping block 1 217 and the clamping block 223 to move together. The straw clamped between the two blocks 223 moves toward the direction close to the limiting mold 17 until the wedge block 1 218 at the top of the clamping block 1 217 contacts 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 plugged into the spray core of the nozzle bottle mouth interface on the limiting mold 17 above it. At the same time, the contact between the wedge block 1 218 and the wedge block 219 causes the clamping block 1 217 to slide in the moving groove 246 in the direction away from the clamping block 223, and then the clamping block 1 217 and the clamping block 223 no longer clamp the straw, so that the telescopic spring 222 is elastically released, and then the moving rod 221 and the clamping block 223 return to the initial position.

[0088] When the electric telescopic rod 22 contracts, the displacement block 26 moves downward, and the downward displacement of the transmission rack 214 drives the clamping block 217 to move downward until the displacement block 26 contacts the contact plate 25, and the clamping block 217 returns to the 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, so that the clamping block 217 moves toward the direction close to the clamping block 223 and plugs into the clamping block 223, so that the clamping block 217 and the clamping block 223 clamp the straw therebetween, so that the straw is fixed.

[0089] When the guide gear rod 28 at the top of the displacement block 1 26 rotates, it drives the transmission bevel gear rod 226 to rotate together, so that the rotating column 227 rotates together with the transmission bevel gear rod 226, and the guide groove three 228 is displaced along with the rotation of the rotating column 227, so that the guide rod 231 moves in the direction close to the guide gear rod 28 along with the shape of the guide groove three 228, thereby driving the displacement block three 229 to move together with the guide rod 231 and elastically compress the return spring two 230, and then through the movement of the displacement block three 229, the displacement block four 232 is driven to move in the cutting groove 244 in the direction close to the limit block two 243, and then the displacement plate one 233 is driven to move together with the displacement block four 232 until the rotating column 227 rotates one circle. At this time, under the elastic release of the return spring two 230 and the guiding action of the guide groove three 228, the guide rod 231 and the displacement block three 229 return to the initial position, thereby driving the displacement block four 232 and the displacement plate one 233 fixed thereon to reset.

[0090] In the process of displacement plate 1 233 moving in the cutting groove 244 in the direction close to limit block 243, when displacement rack 1 237 contacts the inner wall of cutting groove 244, displacement plate 1 233 continues to move, so that displacement rack 1 237 slides in the contraction groove 1 234 in the direction close to displacement block 4 232, thereby driving limit plate 1 235 to move with it and elastically compress the contact spring 236. In this process, displacement rack 1 237 meshes with transmission gear 2 239, thereby driving the rotation away from displacement block 4 232. The rod 238 rotates, and the transmission belt 242 on the transmission wheel 247 fixed on the surface of the rotating rod 238 drives the other rotating rod 238 to rotate together, so that the cutting block 241 is driven by the guide thread groove 240 to approach the middle of the rotating rod 238, so that the two cutting blocks 241 move toward each other until the displacement rack 1 237 is completely retracted into the retracting groove 1 234. At this time, the two cutting blocks 241 collide with each other, and then the straws in the same vertical plane as the middle of the rotating rod 238 are cut off;

[0091] When the displacement block four 232 is reset, during this process, under the action of the elastic release of the resistance spring 236, the limit plate 1 235 drives the displacement rack 1 237 to move towards the direction close to the limit block two 243, thereby causing the transmission gear two 239 to rotate in the opposite direction, and under the action of the transmission belt 242, the two rotating rods 238 rotate in the opposite direction, causing the cutting block 241 to be displaced in the direction away from the middle of the rotating rod 238 under the action of the guide thread groove 240, thereby resetting the cutting block 241.

[0092] During the downward movement of the displacement block 26, in the initial state, the two clamping plates 33 are arranged parallel to one end of the limit block 23, and at this time, a micro motor externally connected to a moving gear rod 32 is started, and the moving gear rod 32 is driven to rotate ninety degrees toward the direction close to the displacement block 26 through its output end, and then the two moving gear rods 32 are meshed to make them move relative to each other, so that the clamping plate 33 rotates together with the moving gear rod 32 on which it is located, so that the clamping plate 33 rotates ninety degrees with the moving gear rod 32 as the axis, and moves toward the direction close to the middle of the displacement block 26;

[0093] When the spray core of the nozzle bottle mouth interface placed on the limiting mold 17 on the displacement block 1 26 is plugged with a straw, at this time, due to the rotation of the moving gear rod 32, the two clamping plates 33 fit in the direction close to the middle of the displacement block 1 26, and the contact block 36 thereon contacts with the straw, and causes the contact block 36 to move in the direction close to the bottom of the displacement groove 3 34, thereby driving the limiting plate 2 35 to move 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, thereby detecting that the straw is plugged into the spray 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 straw, and the second limit plate 35 and the contact block 36 fixed thereto are reset under the elastic release of the compression spring 37.

[0095] When the spray core of the nozzle bottle mouth interface placed on the limiting mold 17 on the displacement block 1 26 is not connected with a straw, the straw that fails to be connected due to the bending of the straw is deformed at the limiting block 243 and stuck at the connection between the limiting block 243 and the guide groove 215, and the displacement block 1 26 conflicts with the contact plate 1 25, and the straw is cut off. At this time, after the clamping plate 33 rotates 90 degrees, the two clamping plates 33 fit together, and when the contact blocks 36 thereon directly conflict, the rotating gear 12 stops rotating, and after the electric telescopic rod 1 22 is fully retracted, the electric telescopic rod 1 22 stops moving, so that the assembly equipment is in a shutdown state;

[0096] After the failed straws are cleaned, the moving gear rod 32 rotates in the opposite direction, and the specific steps are the same as above, so that the clamping plate 33 is reset, and the electric telescopic rod 22 is controlled by the controller to retract, and the straws are inserted again, and the clamping plate 33 is again fitted when the electric telescopic rod 22 is retracted. At this time, the contact block 36 is in conflict with the straw, and when the electric telescopic rod 22 is completely retracted, the rotating gear 12 is started again to make the assembly equipment operate normally;

[0097] When the two contact blocks 36 are directly in contact with each other, the controller is used to stop the assembly equipment, and the controller controls the electric telescopic rod 242 to extend, so that the electric telescopic rod 242 drives the displacement plate 243 to move upward until the electric telescopic rod 242 is extended to the maximum distance. At this time, the displacement plate 243 is at the top of the contraction groove 241 and in contact with the surface of the displacement block 1 26. At this time, the micro motor on the rotating gear 248 is driven, and the rotating gear 248 is driven to rotate through the output end of the micro motor, so that the displacement rack 249 moves toward the direction close to the middle of the rotating gear 248, and then drives the clamping plate 410 fixed on the displacement rack 249 to move toward the direction close to the middle of the limit block 243, so as to clamp the deformed and stuck straw in the limit block 243. The plate 1 25 is in conflict, so that the straw is cut off, and at this time the micro motor on the rotating shaft 45 is driven, so that the rotating shaft 45 is rotated 180 degrees in the direction close to the collecting groove 411, and the rotating plate 46 is rotated together with the rotating shaft 45, so that the deformed straw clamped between the clamping plates 410 is above the collecting groove 411, and at this time the rotating gear 2 48 is rotated in the direction to reset the displacement rack 2 49, and then the clamping plate 410 is reset, and the clamping plate 410 is moved in the direction away from the middle of the rotating gear 2 48, so that the deformed straw clamped between the clamping plates 410 falls into the collecting groove 411, and at this time the rotating shaft 45 is driven in the reverse direction to rotate 180 degrees to reset the rotating shaft 45 and the rotating plate 46, and at this time the electric telescopic rod 2 42 is controlled to shrink, so that the device on the displacement plate 2 43 shrinks into the shrinkage groove 2 41;

[0098] At this time, the assembly of the perfume nozzle joint is completed, and the rotating gear 12 continues to rotate one circle, so that the limiting mold 17 where the assembled perfume nozzle joint is located continues to move, and the assembled perfume nozzle joint is collected by the mechanical clamp 19. With the movement of the rotating gear 12, there are no more parts of the perfume nozzle joint that need to be assembled on the limiting mold 17 at this time, until the limiting mold 17 returns to the initial position, and then the assembly continues, and so on.
