Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

An embodiment of the present invention provides a sealing structure 1, as shown in fig. 1 to 5, the sealing structure 1 includes a rotating shaft 11, a mounting seat 12, and two sealing rings 13. One end of the rotating shaft 11 is used for connecting the manipulator assembly 21 of the plug-in head mechanism 2, an air channel 111 is formed at one end of the rotating shaft 11 along the axial direction of the rotating shaft 11, and a first air inlet 112 penetrating through the air channel 111 is further formed in the peripheral surface of the rotating shaft 11. The mounting base 12 is provided with a mounting through hole 121 and a second air inlet hole 122, the mounting through hole 121 is provided with an air inlet section 1211, the rotating shaft 11 rotatably penetrates through the mounting through hole 121, the first air inlet hole 112 is located in the air inlet section 1211, the second air inlet hole 122 penetrates through the surface of the mounting base 12 and the section wall of the air inlet section 1211, and one end of the second air inlet hole 122 away from the air inlet section 1211 is used for connecting an external air supply mechanism (not shown in the figure). Two sealing rings 13 are respectively arranged on two sides of the air inlet section 1211 along the axial direction of the mounting through hole 121, the rotating shaft 11 penetrates through the two sealing rings 13, each sealing ring 13 comprises an outer periphery 131 and an inner periphery 132, grooves 133 are formed in the outer periphery 131 and the inner periphery 132 along the circumferential direction of the sealing ring 13 so as to form outer periphery sealing bulges 134 on two sides of the outer periphery 131, inner periphery sealing bulges 135 are formed on two sides of the inner periphery 132, the outer periphery sealing bulges 134 are in compression joint with the hole wall of the mounting through hole 121, and the inner periphery sealing bulges 135 are in compression joint with the rotating shaft 11.

Specifically, in order to make the card head mechanism 2 capable of coping with various card insertion situations such as irregular electronic components and jack offset, the robot assembly 21 of the card head mechanism 2 is required to be horizontally rotatable. In order to enable the robot assembly 21 to rotate, in the present embodiment, the mounting base 12 is provided with a mounting through hole 121, the rotating shaft 11 is rotatably disposed through the mounting through hole 121, and since one end of the rotating shaft 11 is used for connecting the robot assembly 21, the rotating shaft 11 is driven to rotate to drive the robot assembly 21 to rotate horizontally.

The power source of the robot assembly 21 is an external air supply mechanism, when the external air supply mechanism supplies air to the second air inlet 122, the air first flows into the air inlet 1211 through the second air inlet 122, then flows into the first air inlet 112 through the air inlet 1211, then flows into the air channel 111 through the first air inlet 112, and finally flows to the robot assembly 21 of the plug-in head mechanism 2 through the air channel 111, so that the robot assembly 21 obtains power for transporting external electronic components (not shown). Since the rotating shaft 11 is disposed through the mounting hole 121 of the mounting seat 12, when the air flows from the air inlet 1211 to the first air inlet 112, a part of the air leaks out through two ends of the mounting hole 121, and this air leakage may result in insufficient power of the robot assembly 21, and when the air leakage is serious, the robot assembly 21 may not pick up an external electronic component, which may seriously delay the production process.

Through the embodiment, the sealing rings 13 are arranged on the two sides of the air inlet section 1211 along the axial direction of the mounting through hole 121, when air leaks from the air inlet section 1211, the air will flow through the sealing ring 13 first, and as long as the outlet is blocked by the sealing ring 13, the air leakage phenomenon can be avoided, and in order to improve the sealing capability of the sealing ring 13, the path of the air leakage is completely closed by the sealing ring 13, in the embodiment, the grooves 133 are arranged on the outer periphery 131 and the inner periphery 132 of the sealing ring 13 along the circumferential direction of the sealing ring 13, so that the outer periphery sealing bulges 134 are formed on the two sides of the outer periphery 131, the inner periphery sealing bulges 135 are formed on the two sides of the inner periphery 132, the outer periphery sealing bulges 134 are in pressure joint with the hole wall of the mounting through hole 121, the inner periphery sealing bulges 135 are in pressure joint with the rotating shaft 11, when the air is about to break through the blocking of the sealing ring 13, the outer periphery sealing bulges 134 on the two sides of the outer periphery 131 or the inner periphery sealing bulges 135 are broken through the inner periphery 132 in sequence, the outer sealing bulge 134 and the inner sealing bulge 135 realize double sealing, the air tightness is very good, the air leakage phenomenon is further avoided, the normal operation of the mechanical arm assembly 21 is ensured, and the production process is not delayed. In addition, in the seal ring 13 of the present embodiment, only the inner peripheral sealing protrusion 135 of the inner periphery 132 contacts with the rotating shaft 11, and only the outer peripheral sealing protrusion 134 of the outer periphery 131 contacts with the hole wall of the installation through hole 121, so the contact area is small, the friction force is relatively low, the resistance caused by the seal ring 13 when the rotating shaft 11 rotates is greatly reduced, meanwhile, the abrasion of the seal ring 13 can be reduced, and the seal ring 13 is durable. When the outer peripheral sealing protrusion 134 or the inner peripheral sealing protrusion 135 is slightly worn, the sealing ring 13 is subjected to stress due to the pressure applied to the sealing ring 13 by the rotating shaft 11 and the hole wall of the installation through hole 121, and the stress can drive the sealing ring 13 to compensate for a certain degree, so that the sealing ring 13 cannot lose sealing capability due to slight wear.

In an embodiment, as shown in fig. 3 to 4, the mounting through hole 121 further includes two narrowing sections 1212 respectively disposed at two sides of the air inlet section 1211 along a radial direction of the mounting through hole 121 and located between the two sealing rings 13, and an aperture of the narrowing section 1212 is smaller than an aperture of the air inlet section 1211.

Specifically, since the aperture of the narrowing section 1212 is smaller than the aperture of the air inlet section 1211, the air in the air inlet section 1211 cannot naturally pass through the narrowing section 1212, and the narrowing section 1212 generates resistance to prevent the air from flowing to the sealing ring 13, thereby further preventing air leakage, ensuring normal operation of the robot assembly 21, and not delaying the production process.

In an embodiment, as shown in fig. 4, the mounting through hole 121 further includes two sealing ring mounting sections 1213, the sealing ring mounting sections 1213 are respectively adjacent to the two narrowing sections 1212 away from the air inlet section 1211, the aperture of the sealing ring mounting section 1213 is larger than that of the narrowing section 1212, and the sealing ring 13 is mounted in the sealing ring mounting section 1213.

Specifically, when the sealing ring 13 is installed in the sealing ring installation section 1213, since the aperture of the sealing ring installation section 1213 is greater than the aperture of the narrowing section 1212, the narrowing section 1212 can limit the sealing ring 13, and no matter how the sealing ring 13 is displaced, the sealing ring 13 cannot slide into the air inlet section 1211, thereby avoiding the occurrence of air leakage.

In an embodiment, the sealing structure 1 further includes two bearings 14, the two bearings 14 are respectively disposed on the sides of the two sealing rings 13 away from the air inlet 1211, and the rotating shaft 11 is disposed through the two bearings 14, so that the rotating shaft 11 is rotatably connected to the mounting seat 12.

Specifically, the bearing 14 can reduce the friction coefficient during the rotation of the rotating shaft 11, and improve the rotation accuracy of the rotating shaft 11.

In an embodiment, as shown in fig. 4, the sealing structure 1 further includes two gaskets 15, the gaskets 15 are respectively disposed on a side of the two sealing rings 13 away from the air inlet section 1211, and a side of the two bearings 14 close to the air inlet section, and the rotating shaft 11 is disposed through the two gaskets 15.

Specifically, the gasket 15 can prevent the bearing 14 from directly contacting the seal ring 13, so that the seal ring 13 is prevented from being rubbed when the bearing 14 rotates, and the service life of the seal ring 13 is prolonged. During assembly, due to the existence of the gasket 15, the bearing 14 can be prevented from excessively penetrating into the mounting through hole 121, and the bearing 14 can be conveniently mounted. When the bearing 14 is too deep into the seal ring 13, the seal ring 13 is excessively pressed, and resistance when the rotating shaft 11 rotates becomes large, so that accuracy of rotation of the rotating shaft 11 becomes low.

In one embodiment, as shown in fig. 4-5, the outer peripheral surface of the bearing 14 is provided with a rib 141, the rib 141 is disposed around the outer peripheral surface of the bearing 14, the rib 141 is located at one side of the outer peripheral surface of the bearing 14, and the rib 141 is configured to abut against the surface of the mounting seat 12.

Specifically, the ribs 141 facilitate the installation of the bearing 14, and when the bearing 14 is installed, the bearing 14 can be installed only when the ribs 141 abut against the surface of the mounting seat 12.

In one embodiment, as shown in FIGS. 4-5, the groove 133 is "︶" shaped.

Specifically, because the rotating shaft 11 and the hole wall of the mounting through hole 121 apply pressure to the sealing ring 13, stress is generated inside the sealing ring 13, and the ︶ -shaped groove 133 enables the stress inside the sealing ring 13 to be distributed more evenly, so that the airtightness is better, the occurrence of air leakage is further avoided, the normal operation of the manipulator assembly 21 is ensured, and the production process is not delayed. When the sealing ring 13 is worn, the wear-resistant sealing ring can be compensated better, and the service life of the sealing ring 13 is further prolonged.

Of course, it is understood that the groove 133 may also take a "+", "U", "︺", "V", etc., which can be adaptively adjusted by those skilled in the art.

Preferably, the sealing ring 13 is made of rubber. The sealing ring 13 made of rubber has excellent sealing effect and small movement friction resistance, so that the sealing ring is suitable for dynamic sealing and mechanical equipment with high precision requirement.

Of course, it is understood that the sealing ring 13 may be made of silicon rubber, fluorine rubber, or other materials.

The embodiment of the present invention shows a sealing structure 1, as shown in fig. 1-5, by arranging sealing rings 13 at two sides of an air inlet section 1211 along an axial direction of an installation through hole 121, when air leaks from the air inlet section 1211, the air will flow through the sealing rings 13 first, as long as an outlet path is blocked by the sealing rings 13, the occurrence of air leakage can be avoided, in order to improve the sealing capability of the sealing rings 13, so that the sealing rings 13 completely seal the path of air leakage, in this embodiment, grooves 133 are arranged on an outer periphery 131 and an inner periphery 132 of the sealing rings 13 along a circumferential direction of the sealing rings 13, so that outer periphery sealing protrusions 134 are formed at two sides of the outer periphery 131, inner periphery sealing protrusions 135 are formed at two sides of the inner periphery 132, the outer periphery sealing protrusions 134 are in pressure connection with a hole wall of the installation through hole 121, the inner periphery sealing protrusions 135 are in pressure connection with a rotating shaft 11, when air is to break through the blocking of the sealing rings 13, the outer periphery sealing protrusions 134 need to be broken through in sequence, or the inner circumference sealing bulges 135 on both sides of the inner circumference 132, namely the outer circumference sealing bulge 134 and the inner circumference sealing bulge 135 realize double sealing, the air tightness is very good, the air leakage phenomenon is further avoided, the normal operation of the mechanical arm assembly 21 is ensured, and the production process is not delayed. In addition, in the seal ring 13 of the present embodiment, only the inner peripheral sealing protrusion 135 of the inner periphery 132 contacts with the rotating shaft 11, and only the outer peripheral sealing protrusion 134 of the outer periphery 131 contacts with the hole wall of the installation through hole 121, so the contact area is small, the friction force is relatively low, the resistance caused by the seal ring 13 when the rotating shaft 11 rotates is greatly reduced, meanwhile, the abrasion of the seal ring 13 can be reduced, and the seal ring 13 is durable. When the outer peripheral sealing protrusion 134 or the inner peripheral sealing protrusion 135 is slightly worn, the sealing ring 13 is subjected to stress due to the pressure applied to the sealing ring 13 by the rotating shaft 11 and the hole wall of the installation through hole 121, and the stress can drive the sealing ring 13 to compensate for a certain degree, so that the sealing ring 13 cannot lose sealing capability due to slight wear.

The embodiment of the invention also provides a plug-in head mechanism 2, as shown in fig. 3-4, the plug-in head mechanism 2 comprises a sealing structure 1, a manipulator assembly 21, a mounting frame 22, a rotating assembly 23 and a lifting assembly 24. The rotating assembly 23 and the lifting assembly 24 are mounted on the mounting frame 22. The sealing structure 1 is the sealing structure 1 of the above embodiment, the mounting base 12 is connected with the lifting assembly 24, and the rotating shaft 11 is connected with the rotating assembly 23. The manipulator assembly 21 is connected with the rotating shaft 11 and communicated with the air channel 111, the manipulator assembly 21 is used for carrying external electronic components, the rotating assembly 23 is used for driving the rotating shaft 11 to rotate so as to drive the manipulator assembly 21 to rotate, and the lifting assembly 24 is used for driving the mounting base 12 to lift so as to drive the manipulator assembly 21 to lift.

In particular, since the electronic component may be irregular, the size and shape of the pins of the irregular electronic component are diversified, and there are large dimensional tolerance and form and position tolerance, so that the pins of the picked-up electronic component are not necessarily aligned with the jacks (not shown in the figure) located in the external plug-in area. The manipulator assembly 21 of the plug-in head mechanism 2 of the present embodiment can be driven by the rotating assembly 23 to horizontally rotate, so that the pins of the electronic component can be aligned to the insertion holes (not shown in the figure) located in the external plug-in area.

The rotating assembly 23 may be pre-driven or real-time driven. The pre-driving is to calculate the angle of the rotation component 23 to be rotated in advance, write the angle into the execution program, and the rotation component 23 drives the rotation shaft 11 to rotate according to the program written in the execution program. The real-time driving is to install the shooting component 25 on the mounting frame 22, and the shooting component 25 is used for shooting the jacks.
