Description

Technical Field

[0001] This utility model relates to the technical field of dental nozzle assembly equipment, and more specifically to an automatic dental nozzle assembly equipment. Background Technology

[0002] A dental cleaning spray gun is a device specifically designed for oral cavity cleaning. Its basic principle is to use compressed air or other power sources to propel liquid (usually water or a disinfectant solution) at a certain pressure and speed from the nozzle, thereby cleaning oral tissues and tooth surfaces. Dental cleaning spray guns require both water and air sprays; therefore, the nozzle typically employs a dual-tube structure, consisting of an inner tube and an outer tube fitted together. The inner tube contains a water channel, while the inner and outer tubes form an air channel, as exemplified by the dental nozzle device with publication number CN115024844A.

[0003] In existing nozzle production processes, the inner and outer tubes are manually assembled, resulting in low production efficiency, high labor costs, and a high error rate and amount of defective products. Therefore, this invention provides an automated dental nozzle assembly device with high assembly efficiency. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an automatic dental nozzle assembly device. Through the cooperation of an inner tube arrangement plate and an inner tube storage box, an inner tube is automatically placed in the inner tube placement slot. Similarly, through the cooperation of an outer tube arrangement plate and an outer tube storage box, an outer tube is automatically placed in the outer tube placement slot. The outer and inner tubes are moved by a second pusher and a first pusher, respectively, while the nozzle placement slot provides limiting. This completes the automatic assembly of the outer and inner tubes, resulting in high assembly efficiency and low labor costs, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic dental nozzle assembly device, including an assembly table, a nozzle arrangement plate inside the assembly table, an inner tube conveying mechanism and an outer tube conveying mechanism on both sides of the nozzle arrangement plate, the inner tube conveying mechanism including an upper and lower fixed inner tube storage box and an inner tube arrangement plate, a plurality of inner tube placement slots opened on the top of the inner tube arrangement plate, a first pusher pin on the side of the inner tube arrangement plate away from the nozzle arrangement plate, the outer tube conveying mechanism including an upper and lower fixed outer tube storage box and an outer tube arrangement plate, a plurality of outer tube placement slots opened on the top of the outer tube arrangement plate, a second pusher pin on the side of the outer tube arrangement plate away from the nozzle arrangement plate, a plurality of nozzle placement slots opened on the top of the nozzle arrangement plate, and the nozzle placement slots, inner tube placement slots and outer tube placement slots correspond one-to-one.

[0006] In a preferred embodiment, the bottom of the inner tube arrangement plate and the bottom of the outer tube arrangement plate are both fixed to the inner wall of the assembly table via a linear module, and the bottom of the nozzle arrangement plate is fixed to the assembly table via an electric push rod, which can automatically adjust the height of the nozzle arrangement plate.

[0007] In a preferred embodiment, the bottom of the first pusher and the bottom of the second pusher are both fixed to the inner wall of the assembly table through the second linear module. The second linear module is located outside the first linear module, and the positions of the first pusher and the second pusher can be automatically adjusted by the second linear module.

[0008] In a preferred embodiment, the inner tube storage box and the outer tube storage box are each provided with a feeding port on the side away from each other. Both feeding ports are hinged with baffles. The two baffles are locked to the outer tube storage box and the inner tube storage box respectively by locks to improve the stability after the baffles are closed.

[0009] In a preferred embodiment, both the inner tube storage box and the outer tube storage box are equipped with pressure blocks. A column is fixed at the center of the top of each pressure block. The two columns pass through the top of the inner tube storage box and the top of the outer tube storage box, respectively. The columns can limit the pressure plate and keep it in a vertical position as it descends.

[0010] In a preferred embodiment, a transport track is provided between the inner tube arrangement plate and the nozzle arrangement plate, and multiple nozzle placement stations are provided on the transport track. Each nozzle placement station has a placement hole that corresponds one-to-one with the nozzle placement slot.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model uses an inner tube arrangement plate and an inner tube storage box to automatically place the inner tube in the inner tube placement slot, and an outer tube arrangement plate and an outer tube storage box to automatically place the outer tube in the outer tube placement slot. The outer tube and inner tube are moved by the second pusher and the first pusher respectively, and the nozzle placement slot is used for limiting. The outer tube and inner tube can be automatically assembled, which has high assembly efficiency and low labor cost.

[0013] 2. By installing flip-open baffles on both the inner and outer tube storage boxes, it is easier for workers to load materials quickly and avoid the problem of bending or tilting of the inner and outer tubes. At the same time, the pressure plates inside the inner and outer tube storage boxes limit the inner and outer tubes respectively, preventing them from tilting when unloading, thereby improving the loading efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides an automatic dental nozzle assembly device, including an assembly table 1. The assembly table 1 has a nozzle arrangement plate 2 inside. The nozzle arrangement plate 2 has an inner tube conveying mechanism 3 and an outer tube conveying mechanism 4 on both sides. The inner tube conveying mechanism 3 includes an inner tube storage box 31 and an inner tube arrangement plate 32 fixed at the top and bottom. The top of the inner tube arrangement plate 32 has a plurality of inner tube placement slots 33. The inner tube arrangement plate 32 has a first pusher 34 on the side away from the nozzle arrangement plate 2.

[0024] The outer tube conveying mechanism 4 includes an outer tube storage box 41 fixed at the top and bottom and an outer tube arrangement plate 42. The top of the outer tube arrangement plate 42 is provided with multiple outer tube placement slots 43. The outer tube arrangement plate 42 is provided with a second pusher 44 on the side away from the nozzle arrangement plate 2. The top of the nozzle arrangement plate 2 is provided with multiple nozzle placement slots 5, and the nozzle placement slots 5, inner tube placement slots 33 and outer tube placement slots 43 correspond one-to-one.

[0025] Furthermore, the bottom of the inner tube arrangement plate 32 and the bottom of the outer tube arrangement plate 42 are both fixed to the inner wall of the assembly table 1 via linear module 1 6. The bottom of the nozzle arrangement plate 2 is fixed to the assembly table 1 via electric push rod 7. The bottom of the first push needle 34 and the bottom of the second push needle 44 are both fixed to the inner wall of the assembly table 1 via linear module 2 8. The linear module 2 8 is located outside the linear module 1 6.

[0026] Furthermore, a transport track 13 is provided between the inner tube arrangement plate 32 and the nozzle arrangement plate 2. The transport track 13 is provided with multiple nozzle placement stations 14, and each nozzle placement station 14 is provided with a placement hole 15 that corresponds one-to-one with the nozzle placement slot 5.

[0027] In actual use, the nozzle arrangement plate 2 moves upward under the drive of the electric push rod 7 to the space between the inner tube arrangement plate 32 and the outer tube arrangement plate 42. Then, the inner tube arrangement plate 32 moves back and forth under the drive of the linear module 6, causing the inner tubes in the inner tube storage box 31 to fall into the inner tube placement slots 33. Each inner tube placement slot 33 contains one inner tube. Similarly, the outer tube arrangement plate 42 moves back and forth under the drive of the linear module 6 at its bottom, causing each outer tube placement slot 43 to contain one outer tube. Then, the second push pin 44, driven by the linear module 8 at its bottom, pushes the outer tubes in the outer tube placement slots 43 into the nozzle placement slots 5 and placement holes 15. Then, the first push pin 34, driven by the linear module 8 at its bottom, pushes the inner tubes in the inner tube placement slots 33 into the outer tubes, thus automatically completing the assembly of multiple nozzles. After that, the nozzle arrangement plate 2 moves downward, and the nozzle placement station 14 with multiple nozzles is transported to the next process by the transport rail 13.

[0028] Refer to the instruction manual appendix Figures 1-5 The inner tube storage box 31 and the outer tube storage box 41 are each provided with a feeding port 9 on the side away from each other. Each feeding port 9 is hinged with a baffle 10. The two baffles 10 are locked to the outer tube storage box 41 and the inner tube storage box 31 respectively by a lock.

[0029] Both the inner tube storage box 31 and the outer tube storage box 41 are equipped with pressure blocks 11. Each pressure block 11 has a column 12 fixed at the center of its top. The two columns 12 pass through the top of the inner tube storage box 31 and the top of the outer tube storage box 41, respectively.

[0030] When feeding the inner tubes, the workers first flip open the baffle 10, then stack a large number of inner tubes in the inner tube storage box 31, and then close the baffle 10. The feeding method for the outer tubes is the same as that for the inner tubes. The setting of the feeding port 9 can improve the feeding speed and also prevent the inner tubes from bending or tilting when placed, thereby improving the subsequent assembly efficiency. At the same time, the pressure plates in the inner tube storage box 31 and the outer tube storage box 41 press on the inner tubes and the outer tubes respectively, which can maintain the stability of the inner tubes and the outer tubes and prevent the inner tubes and the outer tubes from tilting when being fed.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
