Description

Technical Field

[0001] This invention relates to watch assembly technology, specifically to the assembly of O-ring seals. Background Technology

[0002] O-rings are commonly used sealing components with a wide range of applications, including electronic products. For example, O-rings are used in watch challengers. To automate product manufacturing, the O-ring assembly process includes automatic O-ring feeding, automatic O-ring unloading, automatic O-ring assembly, and automatic O-ring unloading. Summary of the Invention

[0003] The technical problem solved by this invention is to provide an automatic feeding mechanism for O-ring seals.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an O-ring feeding mechanism, comprising a feeding box and a long strip feeding module, the feeding module having a feeding channel, one end of the feeding module being mounted on the top side wall of the feeding box, the feeding channel communicating with the inner cavity of the feeding box, the top of the feeding box being sealed with a feeding cover, the bottom of the feeding box having several lower air inlets, the diameter of any lower air inlet being smaller than the outer diameter of the O-ring; the top side wall of the feeding box having a main blowing hole, the main blowing hole being arranged opposite to the inlet of the feeding channel.

[0005] According to the above technical solution, gas blows the O-ring seal in the feeding box through the lower air inlet. Since the top of the feeding box is sealed with a feeding cover, the airflow flows upward into the feeding channel, and the O-ring seal flows upward into the feeding channel with the airflow. External gas is blown into the feeding channel inlet through the main blowing hole, blowing the O-ring seal into the feeding channel.

[0006] In this invention, the batch of O-rings in the feeding box are blown one by one into the feeding channel by the gas from the lower air inlet and the gas from the main blowing hole, and then conveyed outward along the feeding channel.

[0007] This invention utilizes airflow to achieve automatic feeding of O-ring seals.

[0008] A blowing auxiliary hole is provided on the top side wall of the feeding box, located beside the main blowing hole and the feed inlet of the feeding channel. The blowing auxiliary hole can blow the floating O-ring towards the space between the main blowing hole and the feed inlet of the feeding channel, so that the gas from the main blowing hole can accurately blow the O-ring into the feed inlet of the feeding channel.

[0009] The main blowing orifice includes a central main blowing orifice, a first main blowing orifice located on both sides of the central main blowing orifice, and a second main blowing orifice. The auxiliary blowing orifice includes a first auxiliary blowing orifice near the first main blowing orifice and a second auxiliary blowing orifice near the second main blowing orifice. The blowing direction of the central main blowing orifice is parallel to the blowing direction of the first and second main blowing orifices. The blowing direction of the first auxiliary blowing orifice is perpendicular to the blowing direction of the first main blowing orifice. The blowing direction of the second auxiliary blowing orifice is perpendicular to the blowing direction of the second main blowing orifice.

[0010] Let the line connecting the central main blowing orifice and the feed inlet of the feeding channel be the centerline. The resultant force of the gas from the first auxiliary blowing orifice and the gas from the first main blowing orifice forms an angle of 45 degrees with the direction of the gas from the first auxiliary blowing orifice, an angle of 45 degrees with the direction of the gas from the first main blowing orifice, and an angle of 45 degrees with the centerline. The resultant force of the gas from the second auxiliary blowing orifice and the gas from the second main blowing orifice also forms an angle of 45 degrees with the direction of the gas from the second auxiliary blowing orifice, an angle of 45 degrees with the direction of the gas from the second main blowing orifice, and an angle of 45 degrees with the centerline. The resultant force of the gas from the first auxiliary blowing orifice and the gas from the first main blowing orifice is perpendicular to the resultant force of the gas from the second auxiliary blowing orifice and the gas from the second main blowing orifice. The direction of the total resultant force formed by the resultant forces of the gas from the first auxiliary blowing orifice and the gas from the first main blowing orifice coincides with the direction of the gas from the central main blowing orifice. Thus, with the cooperation of the first auxiliary blowing hole and the second auxiliary blowing hole, the central main blowing hole, the first main blowing hole, and the second main blowing hole can gather the O-rings on the side of the center line to the center line and blow them into the feed inlet of the feeding channel.

[0011] The auxiliary blowing holes include a third and a fourth auxiliary blowing hole located on either side of the feed inlet of the feeding channel. The third and fourth auxiliary blowing holes are positioned opposite each other, and their blowing direction is perpendicular to the blowing direction of the central main blowing hole. The gas from the third and fourth auxiliary blowing holes can blow the O-rings on either side of the feed inlet of the feeding channel into the feed inlet, facilitating the smooth entry of the O-rings into the feed inlet.

[0012] The feeding module consists of an upper plate and a lower plate. The lower plate has a feeding channel, and the upper plate covers the lower plate. One end of the upper plate extends into the inner cavity of the feeding box, while one end of the lower plate is flush with the inner wall of the feeding box. The portion of the upper plate extending into the inner cavity of the feeding box guides the O-ring seal into the feeding channel inlet. Under the action of upward airflow, the O-ring seal is flat against the bottom surface of the upper plate. Under the action of horizontal airflow, the O-ring seal moves along the bottom surface of the upper plate and enters the feeding channel inlet.

[0013] The feeding module has a feeding platform at its outlet, equipped with a limiting plate and a limiting groove. The O-ring from the feeding module's outlet arrives at the feeding platform and stops in the limiting groove. Below the feeding module is a lifting cylinder, whose piston is connected to a positioning pin. The positioning pin passes through the feeding platform from bottom to top and inserts into the O-ring on the platform. Under airflow, the O-ring enters the feeding channel and moves along it, exiting through the channel and onto the feeding platform. Due to the limiting groove, the O-ring stops at the feeding platform, thus positioning it within the limiting groove. Then, driven by the lifting cylinder, the positioning pin rises, inserts into the O-ring, and protrudes upwards from the clearance notch on the limiting plate. Thus, the O-ring is positioned on the positioning pin.

[0014] The limiting plate is connected to the horizontal cylinder. One end of the feeding module is mounted on the support plate. The support plate is equipped with a horizontal guide rail. The slider on the horizontal guide rail is connected to the limiting plate. The horizontal cylinder is installed at the bottom of the support plate.

[0015] When the material handling mechanism picks up material, the horizontal cylinder operates, driving the limiting plate to move horizontally, exposing the O-ring seal positioned on the locating pin. Then, the material handling mechanism removes the O-ring seal from the locating pin. For example, the material handling head descends and abuts against the top of the locating pin; the locating pin descends while the material handling head remains abutting against it and descends accordingly, causing the O-ring seal to disengage from the locating pin and transfer to the material handling head.

[0032] like Figure 1 , Figures 7 to 10 An O-ring feeding mechanism includes a feeding box 10 and a long strip feeding module 20. The feeding module is provided with a feeding channel 21. One end of the feeding module is mounted on the top side wall of the feeding box. The feeding channel is connected to the inner cavity of the feeding box. The top of the feeding box is sealed with a feeding cover 30. The bottom of the feeding box is provided with several lower air inlets 11. The diameter of any lower air inlet is smaller than the outer diameter of the O-ring. The top side wall of the feeding box is provided with a main blowing hole, which is opposite to the inlet of the feeding channel.

[0033] Gas blows the O-ring seal in the feeding box 10 through the lower air inlet 11. Since the top of the feeding box 10 is sealed with a feeding cover 30, the airflow flows to the feeding channel 21, and the O-ring seal flows to the feeding channel 21 with the airflow. External gas is blown to the feeding channel inlet 210 through the main blowing hole, blowing the O-ring seal into the feeding channel 21.

[0034] A blowing auxiliary hole is provided on the top side wall of the feeding box 10. The blowing auxiliary hole is located beside the main blowing hole and the feeding channel inlet 210. The blowing auxiliary hole can blow the floating O-ring seals into the space between the main blowing hole and the feeding channel inlet 210. In this way, the gas from the main blowing hole can accurately blow the O-ring seals into the feeding channel inlet.

[0035] like Figure 9 , Figure 10 The main blowing hole includes a central main blowing hole 12, a first main blowing hole 13 located on both sides of the central main blowing hole, and a second main blowing hole 14. The auxiliary blowing hole includes a first auxiliary blowing hole 15 near the first main blowing hole and a second auxiliary blowing hole 16 near the second main blowing hole. The blowing direction of the central main blowing hole is parallel to the blowing direction of the first and second main blowing holes. The blowing direction of the first auxiliary blowing hole is perpendicular to the blowing direction of the first main blowing hole, and the blowing direction of the second auxiliary blowing hole is perpendicular to the blowing direction of the second main blowing hole.

[0036] Let the line connecting the central main blowing hole 12 and the feed inlet 210 of the feeding channel be the centerline. The resultant force direction of the gas from the first auxiliary blowing hole 15 and the gas from the first main blowing hole 13 forms an angle of 45 degrees with the direction of the gas from the first auxiliary blowing hole 15, an angle of 45 degrees with the direction of the gas from the first main blowing hole 13, and an angle of 45 degrees with the centerline. The resultant force direction of the gas from the second auxiliary blowing hole 16 and the gas from the second main blowing hole 14 forms an angle of 45 degrees with the direction of the gas from the second auxiliary blowing hole 16, an angle of 45 degrees with the direction of the gas from the second main blowing hole 14, and an angle of 45 degrees with the centerline. The resultant force direction of the gas from the first auxiliary blowing hole 15 and the gas from the first main blowing hole 13 is perpendicular to the resultant force direction of the gas from the second auxiliary blowing hole 16 and the gas from the second main blowing hole 14. The combined force of the gas from the first auxiliary blowing hole 15 and the gas from the first main blowing hole 13, together with the combined force of the gas from the second auxiliary blowing hole 16 and the gas from the second main blowing hole 14, forms a total force whose direction coincides with the direction of the gas from the central main blowing hole 12. Thus, with the cooperation of the first auxiliary blowing hole 15 and the second auxiliary blowing hole 16, the central main blowing hole 12, the first main blowing hole 13, and the second main blowing hole 14 can gather the O-rings beside the centerline to the centerline and blow them into the feed inlet 210 of the feeding channel.

[0037] The auxiliary blowing holes include a third auxiliary blowing hole 17 and a fourth auxiliary blowing hole 18 located on both sides of the feed inlet 210 of the feeding channel. The third and fourth auxiliary blowing holes are arranged opposite each other, and their blowing direction is perpendicular to the blowing direction of the central main blowing hole 12. The gas from the third auxiliary blowing hole 17 and the fourth auxiliary blowing hole 18 can blow the O-rings on the sides of the feed inlet 210 of the feeding channel to the feed inlet of the feeding channel, which facilitates the smooth entry of the O-rings into the feed inlet of the feeding channel.

[0038] like Figure 8 The feeding module 20 includes an upper plate 22 and a lower plate 23. The lower plate has a feeding channel 21, and the upper plate covers the lower plate. One end of the upper plate extends into the inner cavity of the feeding box 10, and one end of the lower plate is flush with the inner wall of the feeding box. The portion of the upper plate 22 extending into the inner cavity of the feeding box 10 guides the O-ring seal into the feeding channel inlet 210. Under the action of upward airflow, the O-ring seal is flat against the bottom surface of the upper plate 22. Under the action of horizontal airflow, the O-ring seal moves along the bottom surface of the upper plate 22 and enters the feeding channel inlet 210.

[0039] The feeding module 20 has a feeding platform 24 at its outlet. The feeding platform is equipped with a limiting plate 25. The limiting plate has a limiting groove 251. The O-ring seal from the outlet of the feeding module comes to the feeding platform and stops at the limiting groove. The feeding module has a lifting cylinder 261 at its bottom. The piston of the lifting cylinder is connected to a positioning pin 26. The positioning pin passes through the feeding platform 24 from bottom to top and can be inserted into the O-ring seal on the feeding platform.

[0040] Under the influence of airflow, the O-ring enters the feeding channel 21 and moves along it, exiting through the channel and reaching the feeding platform 24. Due to the presence of the limiting groove 251, the O-ring stops at the feeding platform 24, thus positioning it on the platform and within the limiting groove 251. Then, driven by the lifting cylinder 261, the positioning pin 26 rises, inserts into the O-ring, and protrudes upwards from the clearance notch 253 on the limiting plate 25. In this way, the O-ring is positioned on the positioning pin 26.

[0041] like Figure 1 , Figure 7 The lifting cylinder 261 is mounted on the lifting cylinder mounting plate 262, which is mounted on the support plate 27. The piston of the lifting cylinder 261 is connected to the positioning pin 26 through the connecting plate 263.

[0042] refer to Figures 1 to 5The limiting plate 25 is connected to the horizontal cylinder 252. One end of the feeding module 20 is mounted on the support plate 27, which has a horizontal guide rail 271. The slider on the horizontal guide rail is connected to the limiting plate, and the horizontal cylinder is installed at the bottom of the support plate. When the material handling mechanism picks up material, the horizontal cylinder 252 operates, driving the limiting plate 25 to move horizontally, exposing the O-ring seal positioned on the positioning pin 26. Then, the material handling mechanism removes the O-ring seal from the positioning pin 26. For example, the material handling head descends and abuts against the top of the positioning pin 26. The positioning pin 26 descends while the material handling head remains abutting against it and descends accordingly, causing the O-ring seal to disengage from the positioning pin 26 and transfer to the material handling head.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
