Description

Technical Field

[0001] The present invention relates to the technical field of reducer assembly, and in particular to an intelligent assembly system for a rotating rack assembly of an Internet of Things smart gas meter. Background Art

[0002] The reducer is an important component in the gas meter. At present, when installing the rotating frame assembly in the reducer, the long end of the rotating shaft on the rotating frame assembly needs to be inserted into the reducer housing. Most of the existing methods are assembled manually or by machine. The manual assembly method cannot guarantee that the rotating shaft on the rotating frame assembly can be inserted to the required depth for assembly, which may easily lead to improper assembly of the rotating frame assembly and affect product quality. At the same time, the manual assembly method is time-consuming and labor-intensive. When the rotating frame assembly is assembled by a machine, since the traditional machine cannot ensure that the rotating shaft on the rotating frame assembly is aligned with the assembly hole when grabbing the rotating frame assembly in the feeding device, it is usually necessary to manually install the rotating frame assembly one by one on the assembly machine, which reduces the assembly efficiency of the rotating frame assembly. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, and the purpose is to provide an intelligent assembly system for a rotating frame assembly of an IoT smart gas meter, which can be used to transmit the rotating frame assembly to ensure that the rotating frame assembly can be assembled in an orderly and one-by-one manner, thereby realizing the automatic loading of the rotating frame assembly and improving the assembly efficiency of the rotating frame assembly.

[0004] The present invention is achieved through the following technical solutions:

[0005] The invention discloses an intelligent assembly system of a rotating frame assembly of an IoT smart gas meter, comprising a feeding mechanism and an assembly mechanism, wherein the feeding mechanism comprises a track, and the track can limit the orientation of a rotating shaft on the rotating frame assembly and transport the rotating frame assembly to the assembly mechanism one by one; the assembly mechanism comprises a grabbing assembly and an installation assembly, wherein the grabbing assembly is used to grab the gear of the rotating frame assembly on the output end of the feeding mechanism, and the installation assembly is used to transfer the grabbed rotating frame assembly to an assembly line and can push the rotating shaft of the rotating frame assembly into an assembly hole.

[0006] In view of the prior art, when installing the rotating frame assembly into the sealing ring assembly of the reducer housing, the rotating frame assembly is usually assembled into the mounting hole manually. However, the above manual installation method is not only inefficient, but also prone to the occurrence of the rotating shaft on the rotating frame assembly not being properly installed when installing the rotating frame assembly, resulting in the product quality not meeting the requirements. Therefore, the technical solution uses the feeding mechanism to automatically feed the rotating frame assembly to be assembled, and the rotating frame assembly in the vibrating plate can be automatically and effectively transferred to the vicinity of the assembly line through the feeding mechanism, waiting for the assembly mechanism to feed the rotating frame assembly on the feeding mechanism. The rotating frame assembly can be taken out, and the feeding mechanism provided in the technical solution can arrange the rotating frame assembly coming out of the vibration plate in an orderly manner on the feeding mechanism according to a certain direction, so as to facilitate the subsequent rapid assembly of the rotating frame assembly and improve the assembly efficiency of the rotating frame assembly; and the provided assembly mechanism mainly includes two functions, wherein the function of the grabbing assembly is to grab the rotating frame assembly arranged on the feeding mechanism, and the function of the installation assembly is to transfer the grabbed rotating frame assembly from the feeding mechanism to the assembly line, and can also install the rotating frame assembly on the grabbing assembly into the assembly hole of the rotating frame assembly, so as to realize the automatic assembly of the rotating frame assembly.

[0007] Furthermore, the feeding mechanism includes a track and a height-adjustable mounting seat, a linear vibrator is also provided on the top of the mounting seat, a connecting block is provided on the top of the linear vibrator, and the bottom of the track is connected to the top of the connecting block; the track includes a slide rail for carrying a rotating frame assembly and a limit plate located on the top of the slide rail, the bottom of the slide rail is connected to the top of the connecting block, a strip opening is provided on the top of the limit plate, the strip opening is distributed along the direction of the track and is connected to the slide rail, and one end of the rotating shaft of the rotating frame assembly can be inserted into the strip opening; both sides of the inner wall of the strip opening of the limit plate are provided with bosses protruding toward the center, the bosses are distributed along the transmission direction of the slide rail, and the distance between the two bosses is greater than or equal to the outer diameter of the rotating shaft of the rotating frame assembly.

[0008] The track provided in the technical solution can automatically load the rotating frame assembly to be installed. The input end of the track is connected to the vibration plate on the reducer assembly line. When the vibration plate is working, the rotating frame assembly placed in the vibration plate is transferred to the track, and then the track transfers the rotating frame assembly to the output end of the track, waiting for the assembly mechanism on the assembly line to grab the rotating frame assembly on the track; the provided mounting seat is used to fix the linear vibrator on the assembly area of ​​the rotating frame assembly. The provided linear vibrator is an existing structure. When working, it can vibrate the rotating frame assembly located in the track, forcing the rotating frame assembly in the track to move toward the output end, thereby achieving the purpose of automatic loading of the rotating frame assembly.

[0009] Furthermore, the mounting seat includes an adjusting plate and a support seat with an inverted "T" structure, the side wall of the adjusting plate is provided with strip holes distributed in the vertical direction, the side wall of the support seat is provided with a limiting bolt, and the limiting bolt is located in the strip hole of the adjusting plate, and a nut is provided on the limiting bolt.

[0010] In order to facilitate on-site installation and debugging and ensure that the track can be suitable for use requirements of different heights, the height of the mounting seat is set to be adjustable. When the height of the mounting seat needs to be adjusted, loosen the nut on the bolt, adjust the height of the adjustment plate on the side wall of the support seat, tighten the nut, and fix the adjustment plate on the side wall of the support seat, thereby realizing rapid adjustment of the height of the mounting seat.

[0011] The length of the set slide rail is consistent with the length of the limit plate, and the width of the two is also consistent. The set slide rail is used to carry the rotating frame assembly coming out of the vibrating plate, so that it can move in the slide rail and smoothly transport the rotating frame assembly to the exit end of the slide rail; and the strip opening on the set limit plate is used to constrain the rotating shaft of the rotating frame assembly. On the one hand, it can ensure that the rotating frame assembly can move stably in the slide rail, and avoid the automatic deflection of the rotating frame assembly during the movement, which makes the subsequent grasping mechanism unable to effectively pick up the deflected rotating frame assembly. At the same time, because the upper end of the rotating shaft of the rotating frame assembly extends into the strip opening, the subsequent assembly of the rotating frame assembly is convenient.

[0012] On the one hand, the provided boss can limit the width of the strip opening of the limit plate to ensure that the width of the strip opening matches the diameter of the rotating shaft of the rotating frame assembly, thereby stably constraining the rotating shaft of the rotating frame assembly on the limit plate. On the other hand, since there is a certain distance between the provided boss and the slide rail, the distance forms a space for accommodating the upper end of the clamping plate of the rotating frame assembly. Therefore, the space formed by the boss and the slide rail can place the upper end part of the clamping plate of the rotating frame assembly, ensuring that the provided track can stably constrain the rotating frame assembly.

[0013] Furthermore, the upper surface of the slide rail is provided with a first slide groove for accommodating the gear of the rotating frame assembly, the first slide groove is distributed along the transmission direction of the slide rail and passes through both ends of the slide rail; the first slide groove of the slide rail is also provided with a second slide groove for accommodating the clamping plate of the rotating frame assembly, the second slide groove is also distributed along the transmission direction of the slide rail and passes through both ends of the slide rail; the second slide groove of the slide rail is also provided with a third slide groove for accommodating the other end of the rotating shaft of the rotating frame assembly, the third slide groove is distributed in the same manner as the second slide groove, and is also connected to both ends of the slide rail.

[0014] The gear train of the second transmission gear is a gear train that is mounted on the second end of the gear train and is located adjacent to the gear train when the gear train is in the first gear train.

[0015] Furthermore, a first fixed block is provided on the top of the limit plate, and a movable rod is provided on the side wall of the first fixed block, and the movable rod is located on the strip-shaped opening; a swing block for blocking the rotating frame assembly is provided on the output end of the track, and the swing block can swing in a vertical plane, and the swing block is sleeved on the movable rod, and the swing block can swing around the axis of the movable rod.

[0016] The present invention provides a method for preventing the lifting of the lifting device from being lost, so that the lifting device can be easily retracted and the lifting mechanism can be easily retracted, so that the lifting device can be easily retracted and the lifting mechanism can be easily retracted.

[0017] In order to ensure that the swing block can limit the rotating frame assembly on the track and prevent the rotating frame assembly from falling from the track, and at the same time ensure that the swing block can swing freely on the output end of the track, a first fixed block and a movable rod are set. In the initial state, the swing block can limit the upper end of the rotating shaft of the rotating frame assembly on the track under the action of its own gravity and block it in the track. When the material picking mechanism on the assembly line takes the rotating frame assembly in the track, a horizontal force is applied to the swing block, forcing the swing block to rotate upward around the axis of the movable rod. After the rotating frame assembly is taken away, the swing block rotates downward under the action of gravity, and then gradually swings back to the initial position to continue to limit the next rotating frame assembly.

[0018] Furthermore, the swing block is an "L"-shaped structure, one end of the swing block is sleeved on the movable rod, and the other end is located directly above the strip opening. When the rotating frame assembly is transmitted in the track, the rotating frame assembly located in the strip opening can push the swing block to rotate around the axis of the movable rod.

[0019] Preferably, the swing block is an "L"-shaped structure, wherein one end of the swing block is connected to the movable rod so that the swing block can rotate on the movable rod, and the other end is located above the strip opening of the track and can block the rotating shaft of the rotating frame assembly in the strip opening.

[0020] Furthermore, a horizontal plate is provided on the top of the first fixed block, and a counterweight is provided on the horizontal plate. The counterweight includes a counterweight shaft and a counterweight head. The counterweight shaft vertically moves through the horizontal plate and is connected to the counterweight head, and the counterweight head is in contact with a swinging stopper. When the swinging stopper swings upward, the swinging stopper can push the counterweight to move upward on the horizontal plate.

[0021] The counterweight is provided on the one hand to ensure that the swing block can effectively block the rotating frame assembly, thereby preventing the rotating frame assembly in the track from pushing the swing block to rotate, resulting in the inability to stably constrain the rotating frame assembly in the track; on the other hand, after taking out the rotating frame assembly in the track, the counterweight can be used to force the swing block rotating upward to quickly return to its initial state, thereby continuously blocking the rotating frame assembly in the track.

[0022] Furthermore, the installation assembly includes a transfer unit for transferring the rotating frame assembly from the output end of the track to the assembly line, and the transfer unit includes a horizontal moving cylinder and a first slide, and the output end of the horizontal moving cylinder is connected to the first slide.

[0023] When the set transfer unit is working, the horizontal moving cylinder can drive the first slide to reciprocate in the horizontal direction, thereby realizing the adjustment of the horizontal position of the assembly mechanism on the transfer mechanism, ensuring that the installation component can transfer the rotating frame assembly on the output end of the track to the assembly line.

[0024] Furthermore, the transplanting unit also includes a vertical plate, an up and down moving cylinder and a second slide, the vertical plate is located on the top of the first slide, the up and down moving cylinder is located on the side wall of the vertical plate, the output end of the up and down moving cylinder is connected to the second slide, and the top unit is located on the side wall of the second slide.

[0025] The vertical plate is used to be vertically connected to the first slide. When the first slide is driven to move by the horizontal moving cylinder, the vertical plate on the first slide will move synchronously, thereby ensuring that the grabbing assembly can maintain synchronous movement with the first slide in the horizontal direction; when the horizontal moving cylinder moves the assembly mechanism to the assembly line, the up and down moving cylinder can be used to drive the grabbing assembly to move upward in the vertical direction, forcing the rotating frame assembly to move toward the assembly hole, and pre-install the rotating frame assembly into the dynamic sealing assembly of the reducer, thereby realizing the preliminary assembly of the rotating frame assembly.

[0026] Furthermore, a reinforcing rib with an L-shaped structure is provided on the side wall of the vertical plate, and the reinforcing rib is connected to the top of the first slide.

[0027] Since the vertical plate is fixed upright on the top of the first slide, in order to ensure a stable connection between the vertical plate and the first slide, reinforcing ribs are provided, and the two sides of the reinforcing ribs are respectively connected to the first slide and the vertical plate, thereby improving the connection strength between the first slide and the vertical plate and ensuring the stability of the device during operation.

[0028] Furthermore, the mounting assembly also includes an upper lifting unit, which includes a fixed platform, an upper lifting cylinder and a lifting rod. The fixed platform is located on the side wall of the second slide, and the upper lifting cylinder is connected to the fixed platform. A protrusion is provided on the side wall of the fixed platform, and the protrusion is located above the upper lifting cylinder. An L-shaped movable plate is provided on the output end of the upper lifting cylinder, one end of the movable plate vertically passes through the protrusion and is connected to the upper lifting cylinder, and the other end is connected to the lifting rod, and the lifting rod is located in the grabbing assembly.

[0029] The upper lifting unit provided in the present technical solution is used to lift the rotating frame assembly in the grasping assembly upward, thereby forcing the rotating shaft on the rotating frame assembly to be pressed into the mounting hole of the rotating frame assembly to realize the assembly of the rotating frame assembly. When the cylinder moves up and down to pre-install the rotating frame assembly into the dynamic sealing ring assembly, the upper lifting cylinder drives the movable plate to move in the vertical direction in the protrusion, thereby driving the push rod on the movable plate to move upward in the vertical direction, and pressing the rotating shaft of the rotating frame assembly located in the grasping assembly to a specified depth in the dynamic sealing ring assembly.

[0030] Furthermore, the grabbing assembly includes a clamping cylinder, a third slide and two clamping units, the clamping cylinder is located on the raised side wall, the third slide is located on the clamping cylinder, the clamping unit is located in the third slide, and the push rod is located between the two clamping units, the clamping cylinder can adjust the distance between the two clamping units, the end surface of the slide rail facing the assembly mechanism is also provided with a clamping opening, the clamping opening is connected to the lower surface of the limit plate, and the clamping end of the clamping arm can extend into the clamping opening to clamp the rotating frame assembly in the slide rail.

[0031] When the grabbing assembly is used to clamp the rotating frame assembly in the track, the set clamping cylinder is used to drive the two clamping units to move toward the center, forcing the clamping unit to extend into the clamping opening on the track to clamp the rotating frame assembly at the swing block. At this time, the horizontal moving cylinder is used to drive the first slide to move toward the assembly line, forcing the grabbing assembly to move synchronously together, so that the rotating frame assembly clamped by the clamping unit moves horizontally, and applies a force to the swing block, forcing the swing block to rotate around the movable rod, so that the clamped rotating frame assembly can be smoothly moved out of the track and transferred to the assembly line; and when the horizontal moving cylinder transfers the rotating frame assembly to the bottom of the assembly hole, the up and down moving cylinder can be used to drive the rotating shaft on the clamped rotating frame assembly to be pre-loaded into the dynamic sealing ring assembly, and then the clamping unit on the clamping cylinder releases the clamping force on the rotating frame assembly, and the upper push cylinder is used to drive the push rod to move upward, so that the rotating shaft on the rotating frame assembly is pushed into the assembly hole, thereby realizing the automatic assembly of the rotating frame assembly.

[0032] Furthermore, the third slide is also provided with a slide groove, in which two sliders are respectively connected to the clamping unit, and the output end of the clamping cylinder is respectively connected to the two sliders; the clamping unit includes a second fixed block and an L-shaped clamping arm, the second fixed block is connected to the slider, the push rod is located between the two second fixed blocks, one end of the two clamping arms is connected to the second fixed block, and the other ends are respectively facing each other, and the surfaces of the clamping arms facing each other serve as clamping surfaces, and an arc-shaped groove is provided on the clamping surface, and the radius of the arc-shaped groove is the same as the radius of the tooth top circle of the gear on the rotating frame assembly.

[0033] When the grabbing assembly is used to clamp the rotating frame assembly, the clamping cylinder can drive the two sliders located in the slide groove to move toward the center, and the slider then drives the second fixed block to move together, thereby realizing the adjustment of the position between the two clamping arms, and then realizing the clamping of the rotating frame assembly, wherein the cross-sectional dimension of the second fixed block in the vertical direction is larger than the cross-sectional dimension of the clamping arm in the vertical direction, and the second fixed block can be used to improve the overall strength of the clamping unit.

[0034] The clamping unit provided in the present technical solution is used to clamp the gear on the rotating frame assembly. However, in order to prevent the clamping arm from causing damage to the gear during clamping, an arc-shaped groove is further provided on the clamping end face of the clamping arm, and the radius of the arc-shaped groove is the same as the radius of the tooth top circle of the gear on the rotating frame assembly, so that the arc-shaped groove on the clamping arm matches the gear of the rotating frame assembly. In this way, when the clamping arm clamps the gear on the rotating frame assembly, the arc-shaped groove can increase the contact area with the gear, effectively avoiding the situation where the clamping force generated by the clamping arm is concentrated on a certain tooth and causes tooth damage.

[0035] Furthermore, the grabbing assembly also includes a positioning unit for positioning the rotating frame assembly, the positioning unit includes a positioning head and a fixed head, one end of the fixed head is connected to the positioning head, and the other end is provided with a notch, the connecting section of the movable plate and the top rod is located in the notch, and the top of the positioning head is provided with a positioning groove with a width the same as the width of the clamping plate of the rotating frame assembly.

[0036] In order to ensure that the grabbing assembly is in a preset position when clamping the rotating frame assembly in the track, in order to ensure the accuracy of subsequent assembly, and at the same time ensure that the grabbing assembly can effectively grasp the rotating frame assembly, a positioning unit is provided. The provided positioning unit can roughly clamp the rotation direction of the clamping plate of the rotating frame assembly to roughly position the rotating frame assembly. The working process is as follows: when the transplanting unit drives the grabbing assembly to grab the rotating frame assembly on the track, the positioning unit on the grabbing unit moves to the end of the track and forces the clamping plate on the rotating frame assembly to enter the positioning groove on the positioning head, and the positioning groove is used to limit the turning direction of the rotating frame assembly to achieve rough positioning of the rotating frame assembly, and then the clamping unit is used to clamp the gear on the rotating frame assembly, thereby completing the clamping process of the rotating frame assembly.

[0037] Furthermore, a transverse plate is provided on the end of the movable plate facing the upper cylinder, a threaded rod is provided on the transverse plate, the threaded rod penetrates the transverse plate and is connected to the upper cylinder, a nut is provided on the threaded rod, and the nut is located above the transverse plate.

[0038] When the cam is in a state of being moved upward, the cam is moved to a position where the nut is fixed to the top of the lever and the lever is moved to a position where the cam is moved to a position where the lever ...

[0064] The feeding mechanism includes a track 5 and a height-adjustable mounting seat, a linear vibrator 3 is also provided on the top of the mounting seat, a connecting block 4 is provided on the top of the linear vibrator 3, and the bottom of the track 5 is connected to the top of the connecting block 4; the track 5 includes a slide rail 12 for carrying the rotating frame assembly 8 and a limit plate 13 located on the top of the slide rail 12, the bottom of the slide rail 12 is connected to the top of the connecting block 4, and the top of the limit plate 13 is provided with a strip opening 14, the strip opening 14 is distributed along the direction of the track 5 and is connected to the slide rail 12, and one end of the rotating shaft of the rotating frame assembly 8 can be inserted into the strip opening 14; both sides of the inner wall of the strip opening 14 of the limiting plate 13 are provided with bosses 7 protruding toward the center, the bosses 7 are distributed along the transmission direction of the slide rail 12, and the spacing between the two bosses 7 is greater than or equal to the outer diameter of the rotating shaft 20 on the rotating frame assembly 8.

[0065] The track 5 provided in the present technical solution can automatically load the rotating frame assembly 8 to be installed. The input end of the track 5 is connected to the vibration plate on the reducer assembly line. When the vibration plate is working, the rotating frame assembly 8 placed in the vibration plate is transferred to the track 5, and then the track 5 transfers the rotating frame assembly 8 to the output end of the track 5, waiting for the assembly mechanism on the assembly line to grab the rotating frame assembly 8 on the track 5; the provided mounting seat is used to fix the linear vibrator 3 on the assembly area of ​​the rotating frame assembly 8. The provided linear vibrator 3 is an existing structure. When working, it can vibrate the rotating frame assembly 8 located in the track 5, forcing the rotating frame assembly 8 in the track 5 to move toward the output end, thereby achieving the purpose of automatic loading of the rotating frame assembly 8.

[0066] The mounting base includes an adjusting plate 2 and a supporting base 1 with an inverted "T" structure.

On the one hand, it can ensure that the rotating frame assembly 8 can move stably in the slide rail 12 to avoid the automatic deflection of the rotating frame assembly 8 during the movement, resulting in the subsequent grasping mechanism being unable to effectively pick up the deflected rotating frame assembly 8. At the same time, since the upper end of the rotating shaft 20 of the rotating frame assembly 8 extends into the strip opening 14, the subsequent assembly of the rotating frame assembly 8 is convenient.

[0069] On the one hand, the provided boss can limit the width of the strip opening 14 of the limiting plate 13, ensuring that the width of the strip opening 14 matches the diameter of the rotating shaft 20 of the rotating frame assembly 8, thereby stably constraining the rotating shaft 20 of the rotating frame assembly 8 on the limiting plate 13. On the other hand, since there is a certain distance between the provided boss 7 and the slide rail 12, the distance forms a space for accommodating the upper end of the clamping plate 22 on the rotating frame assembly 8. Therefore, the space formed by the boss 7 and the slide rail 12 can accommodate the upper end part of the clamping plate 22 on the rotating frame assembly 8, ensuring that the provided track 5 can stably constrain the rotating frame assembly 8.

[0070] The upper surface of the slide rail 12 is provided with a first slide groove 9 for accommodating the gear of the rotating frame assembly. The first slide groove 9 is distributed along the transmission direction of the slide rail 12 and passes through both ends of the slide rail 12; the first slide groove 9 of the slide rail 12 is also provided with a second slide groove 10 for accommodating the clamping plate of the rotating frame assembly 8. The second slide groove 10 is also distributed along the transmission direction of the slide rail 12 and passes through both ends of the slide rail 12; the second slide groove 10 of the slide rail 12 is also provided with a third slide groove 11 for accommodating the other end of the rotating shaft of the rotating frame assembly 8. The third slide groove 11 is distributed in the same manner as the second slide groove 10 and is also connected to both ends of the slide rail 12.

[0071] Since the rotating frame assembly 8 to be assembled in the present technical solution includes a rotating shaft 20, a clamping plate 22 and a gear 21, in order to ensure that the slide rail 12 can stably carry the rotating frame assembly 8, a first slide groove 9, a second slide groove 10 and a third slide groove 11 are sequentially arranged on the slide rail 12 from top to bottom, wherein the first slide groove 9 is arranged to accommodate the gear 21 of the rotating frame assembly 8, so that when the rotating frame assembly 8 moves in the slide rail 12, the gear 21 of the rotating frame assembly 8 is located in the first slide groove 9, and the second slide groove 10 is arranged to accommodate the rotating frame assembly 8 located at the lower clamping plate, It is ensured that the groove bottom surface of the second slide groove 10 can support the clamping plate of the rotating frame assembly 8 so that it can move in the second slide groove 10, and the third slide groove 11 is used to accommodate the lower end of the rotating shaft 20 of the rotating frame assembly 8, ensuring that the rotating frame assembly 8 moves in the slide rail 12. The rotating shaft 20 at the lower end of the rotating frame assembly 8 can move in the third slide groove 11. Therefore, the first slide groove 9, the second slide groove 10 and the third slide groove 11 can stably constrain the rotating frame assembly 8, ensuring that the rotating frame assembly 8 can stably move in the slide rail 12.

[0072] A first fixed block 6 is also provided on the top of the limit plate 13, and a movable rod 17 is provided on the side wall of the first fixed block 6, and the movable rod 17 is located on the strip-shaped opening 14; a swing block 18 for blocking the rotating frame assembly 8 is provided on the output end of the track 5, and the swing block 18 can swing in a vertical plane, and the swing block 18 is sleeved on the movable rod 17, and the swing block 18 can swing around the axis of the movable rod 17.

[0073] In order to ensure that the rotating frame assembly 8 on the track 5 can be assembled in an orderly and one-by-one manner, the present technical solution is also provided with a swing stopper 18 for temporarily blocking the rotating frame assembly 8 at the process end of the track 5. When the rotating frame assembly 8 in the track 5 moves to the swing stopper 18, the swing stopper 18 blocks it and makes it temporarily stop in the track 5, waiting for the assembly mechanism on the assembly line of the rotating frame assembly 8 to grab it, thereby avoiding the grabbing mechanism on the assembly line of the rotating frame assembly 8 being located on the track 5 when taking the previous rotating frame assembly 8 to the assembly line. The situation that the rotating frame assembly 8 on the track 5 falls off occurs, and when the grasping mechanism takes the rotating frame assembly 8, the rotating frame assembly 8 is forced to apply a horizontal thrust to the swing block 18, so that the swing block 18 can rotate in the vertical plane, removing the restraining force on the rotating frame assembly 8, thereby ensuring that the grasping mechanism can quickly take the rotating frame assembly 8, and when the grasping mechanism on the assembly line grabs the rotating frame assembly 8, the swing block 18 is forced to swing downward under the action of gravity, restores the initial state, and continues to limit the next rotating frame assembly 8.

[0074] In order to ensure that the swing block 18 can limit the rotating frame assembly 8 on the track 5 and prevent the rotating frame assembly 8 from falling from the track 5, and at the same time ensure that the swing block 18 can swing freely on the output end of the track 5, a first fixed block 6 and a movable rod 17 are set. In the initial state, the swing block 18 can limit the upper end of the rotating shaft 20 of the rotating frame assembly 8 on the track 5 under the action of its own gravity, and block it in the track 5. When the material picking mechanism on the assembly line takes the rotating frame assembly 8 in the track 5, a horizontal force is applied to the swing block 18, forcing the swing block 18 to rotate upward around the axis of the movable rod 17. When the rotating frame assembly 8 is taken away, the swing block 18 rotates downward under the action of gravity, and then gradually swings back to the initial position to continue to limit the next rotating frame assembly 8.

[0075] The swing block 18 is an "L"-shaped structure, with one end of the swing block 18 sleeved on the movable rod 17 and the other end located directly above the strip-shaped opening 14. When the rotating frame assembly 8 is transmitted in the track 5, the rotating frame assembly 8 located in the strip-shaped opening 14 can push the swing block 18 to rotate around the axis of the movable rod 17. The swing block 18 is also provided with an inclined surface. When the swing block 18 blocks the rotating shaft 20 on the rotating frame assembly 8, the rotating shaft 20 contacts the inclined surface.

[0076] Preferably, the swing block 18 is an "L"-shaped structure, wherein one end of the swing block 18 is connected to the movable rod 17, so that the swing block 18 can rotate on the movable rod 17, and the other end is located above the strip-shaped opening 14 of the track 5, and can block the rotating shaft 20 of the rotating frame assembly 8 in the strip-shaped opening 14; at the same time, in order to ensure that the rotating frame assembly 8 can smoothly push the swing block 18 to rotate on the movable rod 17, an inclined surface is also provided on the swing block 18, and the inclined surface acts as a guiding surface. When the rotating frame assembly 8 moves in the track 5, the rotating shaft 20 on the rotating frame assembly 8 acts on the inclined surface on the swing block 18, forcing the swing block 18 to rotate around the rotating shaft 20.

[0077] The track 5 is also provided with a sensing control platform, which is connected to the management platform. The sensing control platform is a detection optical fiber, and its working principle is the existing technology, which can detect the rotating frame assembly 8 located at the swing stopper 18 in the track 5.

[0078] A transverse plate 19 is also provided on the top of the first fixed block 6, and a counterweight is provided on the transverse plate 19. The counterweight includes a counterweight shaft 15 and a counterweight head 16. The counterweight shaft 15 vertically moves through the transverse plate 19 and is connected to the counterweight head 16, and the counterweight head 16 is in contact with the swinging stopper 18. When the swinging stopper 18 swings upward, the swinging stopper 18 can push the counterweight to move upward on the transverse plate 19.

[0079] The counterweight is provided on the one hand to ensure that the swing block 18 can effectively block the rotating frame assembly 8, thereby preventing the rotating frame assembly 8 in the track 5 from pushing the swing block 18 to rotate, resulting in the inability to stably constrain the rotating frame assembly 8 in the track 5; on the other hand, after taking out the rotating frame assembly 8 in the track 5, the counterweight can be used to force the swing block 18 rotating upward to quickly return to its initial state, thereby continuously blocking the rotating frame assembly 8 in the track 5.

[0080] The installation assembly includes a transfer unit for transferring the rotating frame assembly 8 from the output end of the track 5 to the assembly line, and the transfer unit includes a horizontal moving cylinder 23 and a first slide 24. The output end of the horizontal moving cylinder 23 is connected to the first slide 24 and to the management platform.

[0081] When the transplanting unit is working, the horizontal moving cylinder 23 can drive the first slide 24 to reciprocate in the horizontal direction, thereby adjusting the horizontal position of the assembly mechanism on the transplanting mechanism, ensuring that the installation component can transfer the rotating frame assembly 8 on the output end of the track 5 to the assembly line.

[0082] The transplanting unit also includes a vertical plate 30, an up and down moving cylinder 26 and a second slide 31. The vertical plate 30 is located at the top of the first slide 24. The up and down moving cylinder 26 is located on the side wall of the vertical plate 30 and connected to the management platform. The output end of the up and down moving cylinder 26 is connected to the second slide 31. The top unit is located on the side wall of the second slide 31.

[0083] The vertical plate 30 is used to be vertically connected to the first slide 24. When the horizontal moving cylinder 23 is used to drive the first slide 24 to move, the vertical plate 30 located on the first slide 24 will move synchronously, thereby ensuring that the grabbing assembly can maintain synchronous movement with the first slide 24 in the horizontal direction; when the horizontal moving cylinder 23 moves the assembly mechanism to the assembly line, the up and down moving cylinder 26 can be used to drive the grabbing assembly to move upward in the vertical direction, forcing the rotating frame assembly 8 to move toward the assembly hole, and pre-install the rotating frame assembly 8 into the dynamic sealing assembly of the reducer, thereby realizing the preliminary assembly of the rotating frame assembly 8.

[0084] The side wall of the vertical plate 30 is further provided with an L-shaped reinforcing rib 29 , and the reinforcing rib 29 is connected to the top of the first slide 24 .

[0085] Since the vertical plate 30 is upright and fixed on the top of the first slide 24, in order to ensure that the vertical plate 30 and the first slide 24 are stably connected, a reinforcing rib 29 is provided. The two sides of the reinforcing rib 29 are respectively connected to the first slide 24 and the vertical plate 30, thereby improving the connection strength between the first slide 24 and the vertical plate 30 and ensuring the stability of the device during operation.

[0086] The mounting assembly also includes an upper lifting unit, which includes a fixed platform 32, an upper lifting cylinder 25 and a push rod 41. The fixed platform 32 is located on the side wall of the second slide 31. The upper lifting cylinder 25 is connected to the fixed platform 32 and to the management platform. A protrusion 43 is provided on the side wall of the fixed platform 32. The protrusion 43 is located above the upper lifting cylinder 25. An L-shaped movable plate 40 is provided on the output end of the upper lifting cylinder 25. One end of the movable plate 40 vertically passes through the protrusion 43 and is connected to the upper lifting cylinder 25, and the other end is connected to the push rod 41. The push rod 41 is located in the grabbing assembly.

[0087] The upper lifting unit provided in the present technical solution is used to lift the rotating frame assembly 8 in the grabbing assembly upward, thereby forcing the rotating shaft on the rotating frame assembly 8 to be pressed into the mounting hole of the rotating frame assembly 8, thereby realizing the assembly of the rotating frame assembly 8. When the upper and lower moving cylinders 26 pre-install the rotating frame assembly 8 into the dynamic sealing ring assembly, the upper lifting cylinder 25 drives the movable plate 40 to move in the vertical direction in the protrusion 43, thereby driving the push rod 41 on the movable plate 40 to move upward in the vertical direction, and pressing the rotating shaft 20 of the rotating frame assembly 8 located in the grabbing assembly to a specified depth in the dynamic sealing ring assembly.

[0088] The grabbing assembly includes a clamping cylinder 27, a third slide 34 and two clamping units 28. The clamping cylinder 27 is located on the side wall of the protrusion 43 and is connected to the management platform. The third slide 34 is located on the clamping cylinder 27. The clamping unit 28 is located in the third slide 34, and the push rod 41 is located between the two clamping units 28. The clamping cylinder 27 can adjust the distance between the two clamping units 28. The end surface of the slide rail 12 facing the assembly mechanism is also provided with a clamping opening, which is connected to the lower surface of the limit plate 13. The clamping end of the clamping arm 37 can extend into the clamping opening to clamp the rotating frame assembly 8 in the slide rail 12.

[0089] When the grabbing assembly is used to clamp the rotating frame assembly 8 in the track 5, the clamping cylinder 27 is used to drive the two clamping units 28 to move toward the center, forcing the clamping unit 28 to extend into the clamping opening on the slide rail 12, and clamping the rotating frame assembly 8 located at the swing block 18. At this time, the horizontal moving cylinder 23 is used to drive the first slide 24 to move toward the assembly line, forcing the grabbing assembly to move synchronously with it, so that the rotating frame assembly 8 clamped by the clamping unit 28 moves horizontally, and exerts a force on the swing block 18, forcing the swing block 18 to move around. The movable rod 17 rotates, so that the clamped rotating frame assembly 8 can be smoothly moved out of the track 5 and transferred to the assembly line; and when the horizontal moving cylinder 23 transfers the rotating frame assembly 8 to the bottom of the assembly hole, the up-and-down moving cylinder 26 can be used to drive the rotating shaft on the clamped rotating frame assembly 8 to be pre-installed into the dynamic sealing ring assembly, and then the clamping unit 28 on the clamping cylinder 27 releases the clamping force on the rotating frame assembly 8, and the upper push cylinder 25 drives the push rod 41 to move upward, so that the rotating shaft on the rotating frame assembly 8 is pushed into the assembly hole, thereby realizing the automated assembly of the rotating frame assembly 8.

[0090] The third slide 34 is also provided with a slide groove, in which two sliders 35 are respectively connected to the clamping unit 28, and the output ends of the clamping cylinder 27 are respectively connected to the two sliders 35; the clamping unit 28 includes a second fixed block 36 and an L-shaped clamping arm 37, the second fixed block 36 is connected to the slider 35, the push rod 41 is located between the two second fixed blocks 36, one end of the two clamping arms 37 is connected to the second fixed block 36, and the other ends are respectively facing each other, and the surfaces of the clamping arms 37 facing each other serve as clamping surfaces, and an arc-shaped groove is provided on the clamping surface, and the radius of the arc-shaped groove is the same as the radius of the tooth top circle of the gear on the rotating frame assembly 8.

[0091] When the grabbing assembly is used to clamp the rotating frame assembly 8, the clamping cylinder 27 can drive the two sliders 35 located in the slide groove to move toward the center, and the slider 35 then drives the second fixed block 36 to move together, thereby realizing the adjustment of the position between the two clamping arms 37, and then realizing the clamping of the rotating frame assembly 8, wherein the cross-sectional dimension of the second fixed block 36 in the vertical direction is larger than the cross-sectional dimension of the clamping arm 37 in the vertical direction, and the second fixed block 36 can be used to improve the overall strength of the clamping unit 28.

[0092] The clamping unit 28 provided in the present technical solution is used to clamp the gear 21 on the rotating frame assembly 8. However, in order to prevent the clamping arm 37 from causing damage to the gear 21 when clamping, an arc-shaped groove is further provided on the clamping end face of the clamping arm 37, and the radius of the arc-shaped groove is the same as the radius of the tooth top circle of the gear 21 on the rotating frame assembly 8, so that the arc-shaped groove on the clamping arm 37 matches the gear 21 of the rotating frame assembly 8. In this way, when the clamping arm 37 clamps the gear 21 on the rotating frame assembly 8, the arc-shaped groove can increase the contact area with the gear 21, effectively avoiding the situation where the clamping force generated by the clamping arm 37 is concentrated on a certain tooth and causes tooth damage.

[0093] The grabbing assembly also includes a positioning unit 39 for positioning the rotating frame assembly 8, and the positioning unit 39 includes a positioning head 45 and a fixed head 42. One end of the fixed head 42 is connected to the positioning head 45, and the other end is provided with a notch. The connecting section of the movable plate 40 and the top rod 41 is located in the notch. The top of the positioning head 45 is provided with a positioning groove with a width the same as the width of the clamping plate of the rotating frame assembly 8.

[0094] In order to ensure that the grasping assembly is in a preset position when clamping the rotating frame assembly 8 in the track 5, in order to ensure that the orientation of the rotating frame assembly 8 is in a preset position, thereby ensuring the accuracy of subsequent assembly and ensuring that the grasping assembly can effectively grasp the rotating frame assembly 8, a positioning unit 39 is provided. The provided positioning unit 39 can roughly clamp the rotation direction of the clamping plate of the rotating frame assembly 8 to roughly position the rotating frame assembly 8. The working process is as follows: when the transplanting unit drives the grasping assembly to grasp the rotating frame assembly 8 on the track 5, the positioning unit 39 on the grasping unit moves to the end of the track 5, and forces the clamping plate on the rotating frame assembly 8 to enter the positioning groove on the positioning head 45, and utilizes the positioning groove to limit the steering of the rotating frame assembly 8 to achieve rough positioning of the rotating frame assembly 8, and then utilizes the clamping unit to clamp the gear 21 on the rotating frame assembly 8, thereby completing the clamping process of the rotating frame assembly 8.

[0095] A transverse plate 44 is also provided on the end of the movable plate 40 facing the upper cylinder 25 , and a threaded rod 33 is provided on the transverse plate 44 . The threaded rod 33 penetrates the transverse plate 44 and is connected to the upper cylinder 25 . A nut is also provided on the threaded rod 33 , and the nut is located above the transverse plate 44 .

[0096] In order to control the rotating shaft 20 on the rotating frame assembly 8 not to be pressed into a deeper length during the process of the push rod 41 pushing the rotating frame assembly 8 upward, a stroke adjustment assembly is provided, which includes a cross plate 44, a threaded rod 33 and a nut. When it is necessary to adjust the maximum upward stroke of the movable plate 40, the height of the nut on the threaded rod 33 is changed by rotating the nut on the threaded rod 33. Since the height of the nut on the threaded rod 33 is fixed, when the upper cylinder 25 works, its output end drives the movable plate 40 to move upward in the protrusion 43, and the movable plate 40 moves upward in the protrusion 43. During the upward movement, the cross plate 44 mounted on the threaded rod 33 can be driven to move together. When the cross plate 44 moves to the nut fixed on the threaded rod 33, the set nut is used to limit the cross plate 44 on the threaded rod 33 from continuing to move upward, thereby controlling the stroke of the movable plate 40 and limiting the maximum displacement of the movable plate 40 driving the push rod 41 to move upward, thereby controlling the displacement of the push rod 41 to push the rotating shaft 20 on the rotating frame assembly 8 into the mounting hole, thereby avoiding the push rod 41 pushing the rotating shaft 20 to over-assemble, resulting in product scrapping.

[0097] Example 2

[0098] The intelligent assembly method of the rotating bracket assembly of the Internet of Things smart gas meter includes the following steps:

[0099] 1) The rotating frame assembly 8 enters the track 5 through the vibration plate, and the track 5 is used to move the rotating frame assemblies one by one toward the output port;

[0100] 2) When the rotating frame assembly located in the track 5 moves to the swing block 18, the swing block 18 blocks the rotating frame assembly;

[0101] 3) The installation assembly drives the grabbing assembly to move to the track 5, and uses the positioning unit 39 to clamp the rotation direction of the rotating frame assembly. After roughly positioning the rotating frame assembly, the clamping unit 28 clamps the rotating frame assembly;

[0102] 4) The horizontal moving cylinder 23 drives the grabbing assembly to move in the horizontal direction. When the clamping unit 28 moves while clamping the rotating frame unit, the rotating frame assembly applies force to the swing block 18, forcing the rotating frame assembly to tilt upward, thereby completing the material removal of the rotating frame assembly in the track 5;

[0103] 5) When the horizontal moving cylinder 23 moves the rotating frame assembly to below the assembly hole on the assembly line, the vertical moving cylinder 26 drives the clamped rotating frame assembly to be installed into the installation hole, the clamping unit 28 releases the clamping of the rotating frame assembly, and the upper push cylinder 25 drives the push rod 41 to move upward to insert the rotating frame assembly into the assembly hole, thereby completing the assembly of the rotating frame assembly.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
