[0015] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] See Figures 1-6 As shown in the figure, this application discloses an automatic plastic ball valve assembly device, including a valve stem feeding mechanism 1, a bracket 2, a valve stem assembly mechanism 3, and a pressing mechanism 4; the valve stem assembly mechanism 3 and the pressing mechanism 4 are both connected to the bracket 2. The pressing mechanism 4 is used to press the valve body 6 located on the turntable 5, and the valve stem assembly mechanism 3 is used to grab the valve stem 7 located at the discharge end of the valve stem feeding mechanism 1 and assemble the valve stem 7 into the valve body 6 located on the turntable 5.

[0017] The valve stem assembly mechanism 3 includes a support base 31, a sliding seat 32, a drive assembly, a rotating shaft 33, and a pneumatic gripper 34. The support base 31 is fixed on the bracket 2, the drive assembly is fixed on the support base 31, and the sliding seat 32 is horizontally slidably connected to the support base 31. The sliding seat 32 is connected to the drive end of the drive assembly, which drives the sliding seat 32 to slide horizontally relative to the support base 31 so that the sliding seat 32 moves closer to or away from the turntable 5. The rotating shaft 33 is axially inserted into the sliding seat 32 and rotatably connected to it. A guide structure is provided between the end of the rotating shaft 33 facing the support base 31 and the support base 31. The pneumatic gripper 34 is fixed on the side wall of the end of the rotating shaft 33 away from the support base 31. The pneumatic gripper 34 is used to grip the valve stem 7 located at the discharge end of the valve stem feeding mechanism 1. When the drive assembly drives the sliding seat 32 to move closer to the turntable 5, the guide structure drives the rotating shaft 33 to rotate so that the sliding seat 32 moves closer to or away from the turntable 5. The valve stem 7 on the pneumatic gripper 34 rotates to a horizontal position and is finally inserted into the valve body 6 in a horizontal direction. With the valve stem assembly mechanism described above, when the drive assembly drives the sliding seat to move away from the turntable and reset, the rotating shaft and the pneumatic gripper can rotate relative to the sliding seat and reset under the action of the guide structure. At this time, the pneumatic gripper can clamp the valve stem in a vertical position at the discharge end of the valve stem feeding mechanism. When the drive assembly drives the sliding seat to move closer to the turntable, the guide structure can drive the rotating shaft and the pneumatic gripper to rotate so that the valve stem on the pneumatic gripper rotates to a horizontal position and is finally inserted into the valve body in a horizontal direction. After the valve stem on the pneumatic gripper is inserted into the valve body, the pneumatic gripper can release the valve stem. In addition, after the valve stem is assembled on the valve body on the turntable, the turntable can rotate and rotate the valve body to be installed with the next valve stem to the valve stem assembly mechanism.

[0018] The guiding structure includes a transmission block 35; the transmission block 35 is fixed on one end of the rotating shaft 33 facing the support base 31, and a roller 36 is rotatably connected to the transmission block 35. The roller 36 is eccentrically positioned with respect to the rotating shaft 33. A guide groove 311 is provided on the support base 31, and the roller 36 is slidably engaged in the guide groove 311. The guide groove 311 includes an arc-shaped section 3111 and a horizontal section 3112. One end of the horizontal section 3112 communicates with the upper end of the guide groove 311, and the other end of the horizontal section 3112 extends horizontally towards the side closer to the turntable 5. By adopting this guiding structure, in the drive assembly... When the component drives the sliding seat to move towards the side closer to the turntable, the roller and guide groove work together to allow the roller to slide along the arc section. During this process, the transmission block, rotating shaft, and pneumatic gripper can rotate, allowing the valve stem on the pneumatic gripper to rotate from a vertical state to a horizontal state. Subsequently, the roller can slide along the horizontal section. During this process, the valve stem on the pneumatic gripper can be horizontally inserted into the valve body on the turntable to assemble the valve stem and valve body. After the valve stem on the pneumatic gripper is inserted into the valve body, the pneumatic gripper can release the valve stem.

[0019] The drive assembly includes a first cylinder 37; the first cylinder 37 is fixed on the support base 31, and the sliding seat 32 is fixed to the piston rod of the first cylinder 37. The first cylinder 37 is used to drive the sliding seat 32 to slide horizontally relative to the support base 31 so that the sliding seat 32 moves closer to or away from the turntable 5. By adopting this drive assembly, the first cylinder can reliably drive the sliding seat to move horizontally relative to the support base, and only a single cylinder is needed to drive the valve stem assembly mechanism to complete the assembly of the valve stem and valve body. It has the advantages of simple drive structure and low cost.

[0020] The valve stem feeding mechanism 1 includes a vibrating feed plate 11, a conveying track 12, and a baffle assembly. The feed end of the conveying track 12 is connected to the discharge end of the vibrating feed plate 11, and the discharge end of the conveying track 12 extends to the valve stem assembly mechanism 3. The baffle assembly is fixed to one side of the conveying track 12. When a valve stem 7 from the vibrating feed plate 11 reaches the discharge end of the conveying track 12, the baffle assembly prevents the next valve stem 7 from continuously moving towards the discharge end of the conveying track 12. By adopting this valve stem feeding mechanism, the vibrating feed plate can continuously feed valve stems into the conveying track, and the valve stems entering the conveying track can move along the conveying track towards the discharge end of the conveying track. The discharge end moves, and a sensor is installed at the discharge end of the conveyor track. When the valve stem reaches the discharge end of the conveyor track, the valve stem can trigger the sensor. At this time, the baffle assembly can prevent the next valve stem from continuously moving towards the discharge end of the conveyor track. When the valve stem located at the discharge end of the conveyor track is removed by the valve stem assembly mechanism, the baffle assembly can release the obstruction of the valve stem, so that the next valve stem can move to the discharge end of the conveyor track. After the next valve stem reaches the discharge end of the conveyor track, the valve stem can trigger the sensor. At this time, the baffle assembly can prevent the next valve stem from continuously moving towards the discharge end of the conveyor track, thus realizing the sequential feeding of valve stems.

[0021] The material blocking assembly includes a second cylinder 13 and a clamping frame 14. The second cylinder 13 is fixed to one side of the conveying track 12. One end of the clamping frame 14 is fixed to the piston rod of the second cylinder 13, and the other end of the clamping frame 14 forms a clamping end and, driven by the second cylinder 13, clamps the next valve rod 7 onto the conveying track 12. By using this material blocking assembly, when the piston rod of the second cylinder drives the clamping frame to move downward, the other end of the clamping frame can clamp the next valve rod onto the conveying track, thereby blocking the next valve rod. When the piston rod of the second cylinder drives the clamping frame to move upward, the clamping frame can release the clamping of the valve rod, allowing the next valve rod to move to the discharge end of the conveying track.

[0022] The clamping mechanism 4 includes a third cylinder 41 and a pressure block 42. The third cylinder 41 is fixed on the bracket 2, and the pressure block 42 is fixed on the piston rod of the third cylinder 41. The third cylinder 41 is used to drive the pressure block 42 to move and press the valve body 6 onto the turntable 5. With the clamping mechanism, when the valve stem and valve body are assembled, the clamping mechanism can press the valve body located on the turntable, thus preventing the valve body from moving and facilitating the assembly of the valve stem and valve body. Furthermore, by adopting the above-mentioned clamping mechanism, when the third cylinder drives the pressure block to move downward, the pressure block can press the valve body onto the turntable. When the third cylinder drives the pressure block to move upward, the pressure block can release the clamping state on the valve body. This clamping mechanism has the advantages of simple structure and low cost.

[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
