Description

Technical Field

[0001] The invention relates to the field of nozzle assembly, in particular to a hidden nozzle automatic assembly device, in particular to a hidden nozzle automatic assembly method, and in particular to a hidden nozzle. Background Art

[0002] The pressing part of the nozzle is usually convex. In order to avoid the liquid being squeezed out and the nozzle being contaminated during storage, a cover is usually used for closed protection. However, after long-term use, the cover is not only easy to fall off, but also the card contact of the cover is worn and easy to fall off under the action of squeezing, which cannot play a stable protective role. For this reason, a retractable hidden nozzle is provided, and the nozzle is extended by pressing when in use. However, since the structure of the hidden nozzle is more complicated than that of the traditional nozzle, and it has certain requirements for installation accuracy, it is time-consuming and labor-intensive to assemble it manually, which seriously affects the processing progress.

[0003] To this end, Chinese patent CN217224460U discloses a device for assembling a drying bottle, which first places an external bottom plug on a positioning module, then stacks an external bottle body and an external connector in sequence, starts a driving module, and then presses down a pressing head, thereby combining the external bottom plug, the external bottle body and the external connector together to form a drying bottle. The device is simple and quick, can effectively improve the assembly efficiency of the drying bottle, and also reduces the burden on workers, without the need for workers to press hard.

[0004] The above equipment uses automatic pressing to replace manual pressing for processing. However, the hidden nozzle is different from the drying bottle and does not require a large downward pressure. It is affected by the structure and requires higher installation accuracy. Once there is a large docking deviation, the parts may be deformed and damaged under the action of the pressing force.

The position of the hidden nozzle 6 is corrected through two groups of push rods 32, and the hidden nozzle 6 is fixed to the processing position, and then stable and precise assembly work is carried out.

The push rod 32 moves under the elastic force of the nitrogen spring 411, and then moves toward the axial direction of the tray 21 through multiple push rods 32. The two parallel push rods 32 of the same group push the hidden nozzle 6 to the middle position, and the position of the hidden nozzle 6 is corrected through the cooperation of the two groups of push rods 32, so as to complete the position correction of the hidden nozzle 6, and then the hidden nozzle 6 is assembled as a whole.

[0039] The present invention realizes the function of limiting the movement of the push rod 32 through the fixed seat 421, the movable block 422, the second elastic member 423, the annular seat 424 and the buckle 425. When the tray 21 moves downward, the tray 21 drives the control component 43, and the control component 43 overcomes the elastic force of the second elastic member 423 to push the movable block 422 downward, so that the movable block 422 is separated from the buckle 425, and the movement of the movable block 422 and the fixed seat 421 is no longer limited by the buckle 425, and then the control component 43 releases the downward movement restriction of the limit component 42 on the push rod 32, and the push rod 32 moves under the elastic force of the nitrogen spring 411, and then moves toward the axis direction of the tray 21 through multiple push rods 32, and the two mutually parallel push rods 32 of the same group push the hidden nozzle 6 to the middle position, and the position of the hidden nozzle 6 is corrected by the cooperation of the two groups of push rods 32, and the position correction of the hidden nozzle 6 is completed, and then the hidden nozzle 6 is assembled as a whole.

The operator places the hidden nozzle 6 on the tray 21, and then overcomes the elastic force of the first elastic member 22 to press down the hidden nozzle 6. When the tray 21 moves downward, the tray 21 drives the second connecting rod 432 to move, and the second connecting rod 432 drives the push block 433 to move through the first connecting rod 431. After contacting the movable block 422, the push block 433 overcomes the elastic force of the second elastic member 423 to push the movable block 422.

After receiving the signal, the first linear driver 123 drives the cover plate 124 to move downward, and the cover plate 124 contacts the hidden nozzle 6 and pushes the hidden nozzle 6 to move downward, and then performs subsequent position correction work. After completing the position correction, the pressing part 6111 of the hidden nozzle 6 is pushed into the main body 61 of the hidden nozzle 6 through the pressing component 12 to assist in subsequent assembly work.

[0044] Reference Figure 4 and Figure 8: The frame 1 is provided with a buffer assembly 33 for controlling the movement of the push rod 32, and the buffer assembly 33 includes a cross bar 331 and a movable rod 332; the cross bar 331 is connected to the first support rod 111, and at least three blocks 3331 are provided on the cross bar 331, and multiple blocks 3331 are equidistantly distributed on the cross bar 331; the movable rod 332 is rotatably set on the first end seat 321, and the movable rod 332 is connected to the first end seat 321 through a torsion spring.

[0045] The present invention realizes the function of controlling the moving speed of the push rod 32 through the cross bar 331, the stopper 3331 and the movable rod 332. The operator places the hidden nozzle 6 on the tray 21, and then overcomes the elastic force of the first elastic member 22 to press down the hidden nozzle 6. When the tray 21 moves downward, the tray 21 drives the second connecting rod 432 to move, and the second connecting rod 432 drives the push block 433 to move through the first connecting rod 431. After the push block 433 contacts the movable block 422, it overcomes the elastic force of the second elastic member 423 to push the movable block 422. When the movable block 422 is separated from the buckle 425, the contact buckle 425 restricts the movement of the movable block 422 and the fixed seat 421. The push rod 32 moves under the elastic force of the nitrogen spring 411, and the push rod 3 2 drives the first end seat 321 and the movable rod 332 located on the first end seat 321 to move. After the movable rod 332 contacts the stopper 3331 on the cross bar 331, the movable rod 332 is affected by the resistance and overcomes the elastic force of the torsion spring to rotate, and the elastic force of the torsion spring hinders the movement of the push rod 32, thereby reducing the moving speed of the push rod 32. As the push rod 32 moves, when the movable rod 332 separates from the stopper 3331, the push rod 32 is accelerated again by the elastic force of the nitrogen spring 411 until the movable rod 332 contacts the next stopper 3331, thereby making the movement of the push rod 32 change periodically, so as to control the moving speed of the push rod 32 and prevent the push rod 32 from violently colliding with the hidden nozzle 6 due to excessive moving speed.
