[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] like Figure 1-Figure 4As shown, an embodiment of the present application provides an automatic resetting assembly platform, including: a base 1, an active supporting mechanism, a driven supporting mechanism and a rotating driving mechanism; wherein the active supporting mechanism and the driven supporting mechanism rotate coaxially and are relatively installed on the base 1 to jointly support the parts to be assembled; the active supporting mechanism is driven and connected to the rotating driving mechanism to rotate vertically around its rotation axis; the center of gravity of the driven supporting mechanism is lower than its rotation axis so that it can rotate vertically under the action of its own gravity and automatically reset.

[0031] In this embodiment, the active supporting mechanism and the driven supporting mechanism are arranged relative to each other and are coaxially rotatably installed on the base 1 to jointly support the parts to be assembled, so that the parts to be assembled are mounted on the base 1 and will not interfere with the assembly platform; when the rotating drive mechanism drives the active supporting mechanism to rotate vertically, due to the connection effect of the parts to be assembled, the driven supporting mechanism will also follow to achieve synchronous vertical rotation, so that the parts to be assembled can be rotated at any angle and can be stopped and assembled at any time without the need for pins (columns) to fix; the parts to be assembled can be disassembled and assembled from this application at any angle, and the active supporting mechanism can be automatically reset under the drive of the rotating drive mechanism, and the driven supporting mechanism can also reset itself under the action of its own gravity; thereby realizing automatic adjustment and automatic reset of any angle of assembly, without the need for manpower to flip over, and without the need for pins (columns) to fix the adjustment angle, with powerful functions and high automation safety.

[0032] like Figure 1-Figure 4 As shown, in some embodiments, both the active support mechanism and the passive support mechanism include a support platform 2; which includes a support plate 21 and an eccentric bracket 22 for mounting the parts to be assembled; wherein the upper end of the eccentric bracket 22 is rotatably mounted on the base 1, and the support plate 21 is mounted on the lower end of the eccentric bracket 22 so that the center of gravity of the support platform 2 is located below its rotation axis. In this embodiment, the support platform 2 of the active support mechanism and the passive support mechanism has the same structure, which improves the structural symmetry and beauty of the present application and reduces the production cost. In actual applications, the installation of the support plate 21 and the assembly parts can be a fixed connection that can be detached (such as spot welding, gluing, etc.), or a detachable connection (such as a connecting component, structural matching, etc.).

[0033] It is worth noting that the center of gravity of the support platform 2 of the driven support mechanism of the present application needs to be located below its rotation axis, while the center of gravity of the support platform 2 of the active support mechanism may or may not be located below its rotation axis. Therefore, in other embodiments, the center of gravity of the active support mechanism may be on its rotation axis, that is, the support platform 2 of the active support mechanism includes a horizontal bracket and a horizontal support plate that are horizontally symmetrically arranged, and the position where the center of gravity of the support platform 2 is located is rotatably mounted on the base 1. Of course, the support platforms 2 of the active support mechanism and the driven support mechanism of the present application may be other structures, such as the integral molding of the support plate 21 and the eccentric bracket 22, but they should also fall within the scope of protection of the present application.

[0034] like Figure 2 As shown, in some embodiments, the eccentric bracket 22 includes: a vertical first link 221, a transverse link 222, a vertical second link 223, a connecting plate 224 and a transverse connecting plate 225; wherein, two transverse links 222 and two vertical second links 223 are assembled into a rectangular frame; the vertical first link 221 is centered and vertically protruded on the rectangular frame, and the upper end of the vertical first link 221 is rotatably mounted on the base 1; the transverse connecting plate 225 is horizontally symmetrically mounted on the lower end of the rectangular frame through the connecting plate 224, and the support plate 21 is horizontally symmetrically mounted on the transverse connecting plate 225. This embodiment realizes the horizontal symmetrical installation of the support plate 21 through a rectangular frame, and the structure is stable and firm with high mechanical strength. Of course, in other embodiments, the transverse connecting plate 225 can be directly installed on the rectangular frame. The support plate 21 can be one or more. In other embodiments, when there are multiple support plates 21, their structures can be the same or different. As Figure 2 As shown, the support plate 21 is an L-shaped plate, the vertical plate and the horizontal connecting plate 225 are arranged vertically parallel and connected by bolts and nuts, and the horizontal plate is used to install the parts to be assembled. In other embodiments, the support plate 21 can also be directly installed on the rectangular frame, and the rectangular frame can also be replaced by other structures such as rectangular plates. The specific adjustment is made according to the actual application, but it should fall within the protection scope of this application.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the driven support mechanism further includes: a driven concave wheel disc 4 and an elastic pin 5; wherein the support platform 2 is rotatably mounted on the base 1 through the driven concave wheel disc 4; the outer edge of the driven concave wheel disc 4 is concave to form a groove 41; the elastic pin 5 is concave-convexly matched with the groove 41 to position the support platform 2 when the support platform 2 is reset. In this embodiment, the fast and flexible positioning of the reset of the driven concave wheel disc 4 can be achieved through the concave-convex matching of the elastic pin 5 and the groove 41, which saves the time required for the automatic reset of the driven support mechanism and makes it easier to achieve the automatic reset without power, speeds up the assembly cycle, and improves the assembly efficiency of the present application. It should be understood that when the elastic pin 5 is not concave-convexly matched with the groove 41, the elastic pin 5 is in contact with the outer edge of the driven concave wheel disc 4 and does not affect the reset of the support platform 2 under its own gravity.

[0036] like Figure 1-Figure 4As shown, in some embodiments, the elastic pin 5 includes: a pin shaft, an elastic member and a guide member; wherein, one end of the pin shaft away from the driven concave wheel disc 4 is connected to the elastic member; the guide member constrains the pin shaft to make linear motion; the pin shaft is concave-convexly matched with the groove 41 under the elastic force of the elastic member. In this embodiment, when the elastic member is in a compressed state, the pin shaft and the outer edge of the driven concave wheel disc 4 slide and rub; when the elastic member is in an extended state, the pin shaft is concave-convexly matched with the groove 41 under the elastic force of the elastic member to achieve the positioning of the support platform 2 and quickly stop the swing. The guide member and the pin shaft can be concave-convexly matched or groove-rail matched to constrain the pin shaft to make linear motion. In actual application, the lower end of the elastic member is installed on the guide member, and the guide member is provided with a slide groove or sleeve corresponding to the pin shaft, the upper end of the elastic member is connected to the pin shaft, and the elastic member is pre-compressed and installed on the guide member so that the pin shaft abuts against the outer edge of the driven concave wheel disc 4. During the forward and reverse rotation of the dynamic support mechanism, when the groove 41 is directly opposite to the pin shaft, the pin shaft will extend into the groove 41 under the elastic force of the elastic member and clamp the driven concave wheel disc 4 to achieve its positioning. In order to reduce the difficulty of matching between the pin shaft and the driven concave wheel disc 4, the outer contour of the side of the pin shaft close to the driven concave wheel disc 4 is a smooth arc surface, the groove 41 is an arc groove and its inner side wall is a circular arc transition wall surface.

[0037] like Figure 1-Figure 4 As shown, in some embodiments, the elastic pin 5 also includes a roller 51; wherein the roller 51 is rotatably mounted on the other end of the pin shaft close to the driven concave wheel disc 4; when the elastic member is in a compressed state, the roller 51 rolls and rubs against the outer edge of the driven concave wheel disc 4; when the elastic member is in an extended state, the roller 51 is concave-convexly matched with the groove 41 under the elastic force of the elastic member. In this embodiment, the roller 51 rolls and rubs against the outer edge of the driven concave wheel disc 4, thereby reducing the difficulty of resetting the support platform 2, making the present application easier to implement. Similarly, in order to reduce the difficulty of matching between the roller 51 and the driven concave wheel disc 4, the outer contour of the roller 51 close to the driven concave wheel disc 4 is a smooth surface, the groove 41 is an arc-shaped groove and its inner side wall is a circular arc transition wall. Of course, in other embodiments, the roller 51 is meshedly connected with the driven concave wheel disc 4.

[0038] like Figure 3 As shown, in some embodiments, the driven concave wheel disc 4 is provided with a bearing oil filling hole 42. In this embodiment, oil is filled through the bearing oil filling hole 42 to ensure smooth rotation of the driven support mechanism on the base 1, thereby extending the service life of the active support mechanism.

[0039] like Figure 1-Figure 4As shown, in some embodiments, the active support mechanism further includes: a travel switch 6 and an active cam disc 7; wherein the travel switch 6 is connected to the rotary drive mechanism; the support platform 2 is rotatably mounted on the base 1 through the active cam disc 7; the outer edge of the active cam disc 7 protrudes outward to form a protrusion 71; when the support platform 2 is in the reset state, the protrusion 71 is directly opposite to the travel switch 6. In practical applications, when the protrusion 71 is directly opposite to the travel switch 6, it indicates that the active support mechanism is successfully reset, and the rotary drive mechanism can be stopped at this time. In practical applications, the cooperation mode of the protrusion 71 and the travel switch 6 can be mechanical positioning or signal positioning, such as when the protrusion 71 rotates to the top of the travel switch 6, the switch of the travel switch 6 is triggered, so that the travel switch 6 sends a signal, and then the rotary drive mechanism is controlled to stop rotating the active support mechanism in time, ensuring the timeliness and accuracy of the reset of the active support mechanism. Of course, in other embodiments, when the protrusion 71 rotates to the top of the travel switch 6, although it does not contact the travel switch 6, it triggers the travel switch 6 to send a signal to control the rotary drive mechanism to stop rotating the active support mechanism in time. Of course, the protrusion 71 and the travel switch 6 are not limited to the above-mentioned cooperation.

[0040] In other embodiments, the active support mechanism can also monitor its rotation angle by using an angle sensor instead of the travel switch 6 and the active cam plate 7, so that it can automatically rotate to the corresponding assembly angle and reset to the original position, which should also fall within the protection scope of the present application.

[0041] like Figure 1-Figure 4 As shown, in some embodiments, the base 1 includes: a U-shaped support frame and a mounting plate 11; wherein the active support mechanism is rotatably mounted on the inner side wall of the U-shaped support frame through the mounting plate 11; and the driven support mechanism is rotatably mounted on the inner side wall of the U-shaped support frame through the mounting plate 11. In this embodiment, both the active support mechanism and the driven support mechanism are mounted inside the U-shaped support frame, and the frame setting of the U-shaped support frame reduces its manufacturing cost and facilitates its placement on other equipment for transportation or handling. Of course, in other embodiments, the base 1 may also be a U-shaped support plate or a combination of a plate and a frame, and the present application does not limit its specific structure.

[0042] like Figure 1-Figure 4As shown, in some embodiments, the rotary drive mechanism is a worm gear reduction motor 3. In this embodiment, the worm gear reduction motor 3 can realize the stopping of the parts to be assembled at any angle, thereby meeting its assembly requirements, and the functionality and coordination are better. In practical applications, the worm gear reduction motor 3 is arranged on the outer wall of the U-shaped support frame. Of course, in other embodiments, the rotary drive mechanism can also be a rotary motor, a gear transmission assembly, a gear rack drive mechanism, etc. When the rotary drive mechanism is a rotary motor, the rotary motor and the active support mechanism are coaxially installed on the base 1. When the rotary drive mechanism is a gear transmission assembly, it includes a motor, a driving gear and a driven gear; wherein the motor is connected to the driving gear, the driving gear is meshed with the driven gear, and the driven gear is coaxially driven with the active support mechanism. When the rotary drive mechanism is a gear rack drive mechanism, it includes a linear drive assembly, a gear and a rack; the gear and the rack are meshed, the gear is coaxially driven with the active support mechanism, and the linear drive assembly drives the rack to perform linear reciprocating motion.

In order to avoid obscuring the concept of the present application, some details known in the art are not described.
