Referring to fig. 1 and 2, the suction nozzle mounting structure provided by the present utility model includes a mounting shaft 10, a nut seat 20, a suction nozzle 30 and a lock nut 40. The inside of the mounting shaft 10 is provided with a first air passage 11, and the inside of the suction nozzle 30 is provided with a second air passage 31. When in assembly, the nut seat 20 is arranged at the bottom end of the mounting shaft 10, the suction nozzle 30 is penetrated into the nut seat 20, the locking nut 40 is locked on the nut seat 20, and the suction nozzle 30 is clamped to prevent the suction nozzle 30 from falling out of the nut seat 20.
The utility model defines that one end of the suction nozzle 30 contacting the mounting shaft 10 is a top end, one end of the suction nozzle 30 contacting the product is a bottom end, and openings communicating with the second air passage 31 are arranged at the top end and the bottom end of the suction nozzle 30. When the air pressure of the second air passage 31 is negative pressure, the opening at the bottom end of the suction nozzle 30 contacts the product to adsorb the product.
The nut seat 20 and the lock nut 40 can mount the suction nozzle 30 on the mounting shaft 10 by screw-fitting. Specifically, a through hole is formed in the center of the nut seat 20, the top end of the suction nozzle 30 can extend into the through hole of the nut seat 20, so that the first air passage 11 is communicated with the second air passage 31, and then the locking nut 40 is screwed on the nut seat 20, and the suction nozzle 30 is fixed by the locking nut 40.
The mounting shaft 10 is used for supporting the whole suction nozzle mounting structure, and the utility model defines one end of the mounting shaft 10 contacting the suction nozzle 30 as a bottom end, and the mounting shaft 10 is provided with an opening communicating with the second air passage 31 at the bottom end. When the first air passage 11 is communicated with an external vacuum generator, the air pressure in the first air passage 11 is negative, and the second air passage 31 communicated with the first air passage 11 is also negative.
The installation shaft 10 can be installed at the driving end of the driving mechanism, and the driving mechanism drives the whole suction nozzle installation mechanism to move, so that the suction nozzle 30 is aligned with the product and adsorbs the product, and then the product is driven to move to a required position. And, the mounting shaft 10 may be selected as a rotation shaft, and may be rotated as needed after the suction nozzle 30 sucks the product, so as to adjust the angle of the product.
When the suction nozzle 30 needs to be replaced due to abrasion, the lock nut 40 can be screwed off the nut seat 20, the worn suction nozzle 30 is taken out of the nut seat 20, a new suction nozzle 30 is put in again, and the lock nut 40 is screwed on the nut seat 20 again, so that the top end of the new suction nozzle 30 is fixed by the lock nut 40, and the replacement process is completed. The whole process of replacing the suction nozzle 30 is simple and quick, and various tools and jigs are not required.
In some embodiments, the lock nut 40 abuts against the suction nozzle 30 in the direction of the mounting shaft 10, so that the top end of the suction nozzle 30 abuts against the bottom end of the mounting shaft 10, and the first air passage 11 communicates with the second air passage 31 at the abutting surface of the suction nozzle 30 and the mounting shaft 10.
The locking nut 40 provides a tight supporting force to enable the suction nozzle 30 and the installation shaft 10 to be tightly attached to each other, so that the air tightness of the communication part of the first air passage 11 and the second air passage 31 can be improved, and the suction force of the suction nozzle 30 is prevented from being influenced.
In some embodiments, the surfaces of the suction nozzle 30 and the mounting shaft 10 that are in contact are planar surfaces. The sealing structure formed by the two planes has good sealing performance, simple structure and difficult occurrence of air leakage. Of course, the mating surfaces of the suction nozzle 30 and the mounting shaft 10 may be provided in other shapes, such as convex and concave mating surfaces.
The first air passage 11 in the mounting shaft 10 and the second air passage 31 in the suction nozzle 30 may be provided with appropriate trajectories as needed. For example, the first air passage 11 extends through the entire mounting shaft 10 along the axis of the mounting shaft 10, and the second air passage 31 extends through the entire suction nozzle 30 along the axis of the suction nozzle 30.
During processing, the diameter of the first air passage 11 can be made larger than that of the second air passage 31, so that the first air passage 11 and the second air passage 31 are aligned with each other. Meanwhile, on the basis of not influencing the adsorption force of the suction nozzle 30, the processing difficulty of the first air passage 11 in the mounting shaft 10 can be reduced, and the processing cost is reduced.
In some embodiments, the nut seat 20 is provided with a first mounting hole 21 and a second mounting hole 22 which are mutually communicated, the nut seat 20 is sleeved on the mounting shaft 10 through the first mounting hole 21, and the top end of the suction nozzle 30 extends into the second mounting hole 22 and abuts against the bottom end of the mounting shaft 10.
The nut seat 20 is simultaneously installed in the installation shaft 10 and the suction nozzle 30 through the first installation hole 21 and the second installation hole 22, and positions of the installation shaft 10 and the suction nozzle 30 are limited, so that an opening at the bottom end of the installation shaft 10 can be aligned with an opening at the top end of the suction nozzle 30, and the first air passage 11 is ensured to be communicated with the second air passage 31.
The diameter of the first mounting hole 21 is the same as or about the same as the diameter of the mounting shaft 10, facilitating the fitting of the mounting shaft 10 within the first mounting hole 21. The diameter of the second mounting hole 22 is the same as or about the same as the diameter of the suction nozzle 30, facilitating the fitting of the suction nozzle 3 into the second mounting hole 22.
In general, the diameters of the mounting shaft 10 and the suction nozzle 30 are not the same, and thus the first mounting hole 21 and the second mounting hole 22 are also set to different diameters. When the mounting shaft 10 is installed in the first mounting hole 21, the junction of the two holes can limit the mounting shaft 10; when the suction nozzles 30 are installed in the second installation holes 22, the installation shaft 10 can limit the suction nozzles 30, so that the height of the suction nozzles 30 is consistent before and after replacement.
Further, the suction nozzle mounting structure further comprises one or more screws, fixing holes 23 which are circumferentially arranged and correspond to the screws in number are formed in the side of the nut seat 20, each fixing hole 23 is communicated with the first mounting hole 21, each screw is in threaded fit with the corresponding fixing hole 23, the screw can be screwed into the fixing hole 23 and abuts against the mounting shaft 10 in the first mounting hole 21 from the side, the mounting shaft 10 is clamped and fixed, and the nut seat 20 and the mounting shaft 10 are fixedly connected.
Also, the number of the screws and the fixing holes 23 may be two or more, and may be spaced apart from the outer periphery of the nut seat 20. For example, when the outer circumference of the nut seat 20 is a cylindrical surface, the fixing holes 23 are arranged along the outer circumference of the nut seat 20.
At this time, by adjusting the distance of screwing each screw into the fixing hole 23, the relative position of the nut seat 20 and the mounting shaft 10 can be adjusted, thereby ensuring that the axis of the suction nozzle 30 coincides with the axis of the mounting shaft 10 and improving the suction accuracy of the suction nozzle 30. For example, when the mounting shaft 10 is a rotation shaft, the center position of the product is less likely to be changed after the suction nozzle 30, which coincides with the axis of the mounting shaft 10, sucks the product and rotates to adjust the angle of the product.
Alternatively, the nut seat 20 and the mounting shaft 10 may be integrally formed, and a mounting hole is directly formed in the nut seat 20, so that the top end of the suction nozzle 30 may extend into the mounting hole and abut against the bottom end of the mounting shaft 10, thereby reducing the number of components of the suction nozzle mounting structure.
In some embodiments, referring to fig. 1-3, the lock nut 40 includes a threaded portion 41 and a clamping portion 42 that are connected to each other, the threaded portion 41 is provided with a threaded hole 411 and is screwed onto the nut seat 20, the clamping portion 42 is provided with a clamping hole 421 that communicates with the threaded hole 411, the suction nozzle 30 is disposed through the clamping hole 421 and the threaded hole 411, and the bottom end of the suction nozzle 30 is exposed out of the clamping hole 421. When the screw portion 41 is screwed to the nut seat 20, the holding portion 42 is used to apply a force to the suction nozzle 30 in the direction of the nut seat 20, so that the suction nozzle 30 abuts against the mounting shaft 10.
Specifically, the outer side of the suction nozzle 30 is provided with a first clamping surface 32, the wall of the clamping hole 421 of the clamping portion 42 is provided with a second clamping surface 422, and when the suction nozzle 30 is inserted into the clamping hole 421 and the threaded hole 411, the second clamping surface 422 abuts against the first clamping surface 32.
For example, the suction nozzle 30 is generally hollow cylindrical in structure, and the tip is provided in a tapered or stepped structure to reduce the volume of the tip portion of the suction nozzle 30 and to avoid interference with the product or other objects during the suction process. The shape of the inside of the holding portion 42 may correspond to the tip structure of the suction nozzle 30, and at this time, the second holding surface 422 and the first holding surface 32 that abut against each other are formed.
Alternatively, the clamping portion 42 may clamp the suction nozzle 30 by other means, such as fixing the suction nozzle 30 by screws after the clamping portion 42 is perforated, and other clamping means are used, which is not limited in the present utility model.
In some embodiments, the first clamping surface 32 and the second clamping surface 422 are tapered, and the taper of the first clamping surface 32 is greater than the taper of the second clamping surface 422.
At this time, the positions of the suction nozzles 30 can be adaptively adjusted by matching the first clamping surfaces 32 with the second clamping surfaces 422, so that the axes of the suction nozzles 30 are aligned with the axes of the mounting shafts 10, the consistency of the positions of the suction nozzles 30 before and after replacement is good, and the heights are kept consistent, so that tools and jigs are not required to be used for adjustment.
