A regulator intelligent assembly and processing equipment

Abstract

This invention discloses an intelligent assembly and processing equipment for pressure regulators, belonging to the field of regulator assembly technology. It includes an assembly table and a positioning seat for placing the pressure regulator. A control ring is rotatably connected to the top of the assembly table. Through the planetary assembly assembly, this invention utilizes the rotation of multiple rotating gears to drive the rotation of multiple spiral covers, synchronously tightening multiple fastening sealing screws axially. This avoids minor misalignment between the upper and lower assembly shells of the pressure regulator. Simultaneously, the inclusion of a calibration assembly and through-beam photoelectric sensors allows the convergence and expansion of multiple calibration plates to synchronously move multiple through-beam photoelectric sensors, controlling and adjusting the diameter of the resulting ring. This facilitates the verticality monitoring and calibration of different components during assembly, preventing misalignment that could obstruct the vertical adjustment of components such as the valve core and compression spring, thus ensuring the adjustment accuracy of the pressure regulator.

Description

Technical Field

[0001] This invention relates to the field of regulator assembly technology, and more particularly to a smart regulator assembly and processing equipment. Background Technology

[0002] A pressure regulator is a device used to regulate the pressure of gas or liquid. It mainly consists of valves, springs, and pressure regulators. Pressure regulators are widely used in engineering fields, especially in industrial process control, such as pharmaceuticals and food production, where strict requirements for gas pressure and flow rate are required.

[0003] During the assembly and production of pressure regulators, the inlet and outlet pipes, valve core, diaphragm, compression spring, and adjustment knob are usually assembled sequentially. However, current assembly methods typically use pre-set axes to assemble the components, lacking vertical correction and alignment during assembly. If components such as the valve core and compression spring are misaligned during assembly, or if some assembled components are not perpendicular, the vertical adjustment movement of the valve core and compression spring will encounter frictional resistance during subsequent use, thus affecting the adjustment accuracy of the pressure regulator. Furthermore, each component of the pressure regulator needs to be vertically tightened and sealed individually during assembly, resulting in low efficiency throughout the assembly process. Therefore, an intelligent assembly and processing equipment for regulators is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the current technology, the assembly of each component is usually carried out by using a pre-set axis, which lacks the correction and adjustment of the perpendicularity of each component during assembly. If the valve core and compression spring and other components are misaligned during assembly, the vertical adjustment movement of the valve core and compression spring will be subject to frictional resistance during subsequent use of the pressure regulator, thus affecting the adjustment accuracy of the pressure regulator. Therefore, an intelligent assembly and processing equipment for regulator is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A regulator intelligent assembly and processing equipment includes an assembly table and a positioning seat for placing a pressure regulator. A control ring is rotatably connected to the top of the assembly table. The top of the control ring is connected to a transition ring through two arc-shaped fixed plates. The top of the transition ring is connected to a planetary assembly assembly through multiple electric push rods. The planetary assembly assembly is connected to a fixing platform. A screw cover for synchronously tightening assembly screws is provided above the fixing platform.

[0007] An annular electrically controlled guide rail is provided above the planetary assembly component. An outer rotating ring is connected to the inner wall of the annular electrically controlled guide rail. An inner fixed ring is provided inside the outer rotating ring. Multiple correction components are provided inside the inner fixed ring. A through-beam photoelectric sensor is connected below the correction components.

[0008] Preferably, the top of the assembly platform is fixedly connected to the bottom of the positioning seat, the top of the positioning seat is provided with a positioning groove that matches the bottom of the pressure regulator, and assembly robotic arms are fixedly connected to the upper surfaces of the left and right sides of the assembly platform.

[0009] Preferably, the planetary assembly consists of a revolution gear ring and multiple rotating gears. The top end of the control ring is fixedly connected to the bottom end of the adapter ring via two arc-shaped fixed plates, and the top end of the adapter ring is fixedly connected to the bottom end of the revolution gear ring via multiple electric push rods.

[0010] Preferably, the orbital gear ring meshes with multiple rotating gears, the bottom end of the positioning platform is fixedly connected to the top end of the positioning seat via a support rod, and the top end of the positioning platform is rotatably connected to the bottom end of the rotating gear via a rotating shaft.

[0011] Preferably, a drive wheel is fixedly connected to the outer wall of the rotating shaft, and a driven wheel is driven by the drive wheel through a transmission chain. The driven wheel has a sliding hole adapted to the spiral cover, and the inner wall of the sliding hole is slidably connected to the outer wall of the spiral cover. An anti-detachment plate is fixedly connected to the top of the spiral cover, and a through hole for the spiral cover to pass through is provided on the fixing platform.

[0012] Preferably, the top end of the orbital gear ring is fixedly connected to the outer wall of the annular electrically controlled guide rail via multiple supporting plates, and the inner wall of the annular electrically controlled guide rail is rotatably connected to the outer rotating ring.

[0013] Preferably, the correction assembly consists of an arc-shaped correction rod and a correction base plate. The inner sidewall of the outer rotating ring is provided with a receiving groove. The inner sidewall of the receiving groove is rotatably connected to one end of the arc-shaped correction rod, and the other end of the arc-shaped correction rod is rotatably connected to the end face of the correction base plate.

[0014] Preferably, the end face of the calibration base plate is rotatably connected to the end face of the inner fixed ring via a pin, the inner fixed ring is fixedly connected to the inner sidewall of the outer rotating ring receiving groove, and the through-beam photoelectric sensor is fixedly connected to the bottom end of the calibration base plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This solution, through the setting of planetary assembly components and spiral covers, can use the rotation of multiple self-rotating gears to drive the rotation of multiple spiral covers, and simultaneously tighten multiple fastening sealing screws axially. This avoids the problem of slight misalignment between the upper and lower assembly shells of the pressure regulator during the tightening process, and also makes the assembly efficiency of the pressure regulator higher.

[0017] 2. This solution, through the setting of calibration components and through-beam photoelectric sensors, can utilize the convergence and unfolding of multiple calibration base plates to drive multiple through-beam photoelectric sensors to move synchronously, controlling and adjusting the annular diameter formed by multiple through-beam photoelectric sensors. This facilitates the calibration and monitoring of the verticality of different components during the assembly of the pressure regulator, avoiding misalignment during the assembly of various components of the pressure regulator, which could cause obstruction during the vertical adjustment movement of the valve core and compression spring in the core components of the pressure regulator, thus ensuring the adjustment accuracy of the pressure regulator.

[0030] Example, refer to Figures 1 to 8 A regulator intelligent assembly and processing equipment includes an assembly table 1 and a positioning seat 2 for placing a pressure regulator 3. A control rotating ring 23 is rotatably connected to the top of the assembly table 1. The top of the control rotating ring 23 is connected to a transition ring 5 through two arc-shaped fixed plates. The top of the transition ring 5 is connected to a planetary assembly assembly through multiple electric push rods 6. The planetary assembly assembly is connected to a fixed platform 9. A screw cover 13 for synchronously tightening assembly screws is provided above the fixed platform 9.

[0031] Furthermore, the top of the assembly platform 1 is fixedly connected to the bottom of the positioning seat 2. The top of the positioning seat 2 has a positioning groove that matches the bottom of the pressure regulator 3. Assembly robotic arms 4 are fixedly connected to the upper surfaces of both sides of the assembly platform 1. The planetary assembly assembly consists of a planetary gear ring 7 and multiple rotating gears 8. The top of the control ring 23 is fixedly connected to the bottom of the adapter ring 5 through two arc-shaped fixed plates. The top of the adapter ring 5 is fixedly connected to the bottom of the planetary gear ring 7 through multiple electric push rods 6. The planetary gear ring 7 meshes with multiple rotating gears 8 respectively. The bottom end of the positioning platform 9 is fixedly connected to the top end of the positioning seat 2 via a support rod 24. The top end of the positioning platform 9 is rotatably connected to the bottom end of the self-rotating gear 8 via a rotating shaft. A drive wheel 10 is fixedly connected to the outer wall of the rotating shaft. A driven wheel 12 is driven by a transmission chain 11. A sliding hole adapted to the spiral cover 13 is opened on the driven wheel 12. The inner wall of the sliding hole is slidably connected to the outer wall of the spiral cover 13. An anti-detachment plate 14 is fixedly connected to the top end of the spiral cover 13. A through hole for the spiral cover 13 to pass through is opened on the positioning platform 9.

[0032] It should be noted that: the bottom inlet / outlet pipe housing of the pressure regulator 3 to be assembled is fitted and installed on the positioning groove of the positioning seat 2. Then, the assembly robotic arms 4 on both sides sequentially grasp the valve core, diaphragm, compression spring, and adjustment knob of the pressure regulator 3 for axial assembly. The assembly of the robotic arms 4 is performed according to the program-set values ​​for positioning and assembly. This is existing technology and will not be elaborated on here. When assembling the vertical housing used to assemble the compression spring in the pressure sensor 3 with the bottom inlet / outlet pipe housing, the assembly robotic arms 4 fix the vertical housing to be assembled in position. Then, the screw cover 13 is put on the screw to be tightened, and the control ring 23 on the assembly table 1 is slowly rotated. The rotation of the control ring 23 will drive the adapter ring 5 to rotate. The rotation of ring 5 will drive the rotation of the orbital gear ring 7 through multiple electric push rods 6. The rotation of the orbital gear ring 7 will drive the rotation of multiple rotating gears 8 on the inner side (the fixed platform 9 where the rotating gears 8 are located remains stationary under the fixed support of the support rod 24, and the fixed fixed platform 9 will not obstruct the light of the photoelectric sensor 22). The rotation of the rotating gears 8 will drive the drive wheel 10 to rotate through the rotating shaft, and then the drive wheel 10 will drive the driven wheel 12 to rotate through the transmission chain 11. The rotation of the driven wheel 12 will drive the screw cover 13 to rotate slowly together, so that the screw cover 13 can drive the screw to be tightened to rotate. During the process of the screw cover 13 driving the screw to tighten continuously, the screw cover 13 will slide in the sliding hole on the driven wheel 12 to prevent the screw cover 13 from detaching from the screw surface during the tightening process.

[0033] The advantages mentioned above are as follows: the rotation of multiple self-rotating gears 8 can drive the rotation of multiple screw covers 13 to tighten multiple fastening and sealing screws axially and synchronously, avoiding the problem of slight misalignment between the upper and lower assembly shells of the pressure regulator 3 during the tightening process, and also making the assembly efficiency of the pressure regulator 3 higher.

[0034] A ring-shaped electrically controlled guide rail 16 is provided above the planetary assembly component. An outer rotating ring 17 is connected to the inner wall of the ring-shaped electrically controlled guide rail 16. An inner fixed ring 20 is provided inside the outer rotating ring 17. Multiple correction components are provided inside the inner fixed ring 20. A photoelectric sensor 22 is connected below the correction components.

[0035] Furthermore, the top of the orbital gear ring 7 is fixedly connected to the outer wall of the annular electronically controlled guide rail 16 through multiple supporting plates 15. The inner wall of the annular electronically controlled guide rail 16 is rotatably connected to the outer rotating ring 17. The correction assembly consists of an arc-shaped correction rod 18 and a correction seat plate 21. The inner wall of the outer rotating ring 17 is provided with a receiving groove. The inner wall of the receiving groove is rotatably connected to one end of the arc-shaped correction rod 18. The other end of the arc-shaped correction rod 18 is rotatably connected to the end face of the correction seat plate 21. The end face of the correction seat plate 21 is rotatably connected to the end face of the inner fixed ring 20 through a pin 19. The inner fixed ring 20 is fixedly connected to the inner wall of the receiving groove of the outer rotating ring 17. The photoelectric sensor 22 is fixedly connected to the bottom end of the correction seat plate 21.

[0036] It should be noted that during assembly, multiple through-beam photoelectric sensors 22 are kept in the open state. The rotation of the orbital gear ring 7 will drive the annular electronically controlled guide rail 16 to rotate via the support plate 15, thereby causing the multiple through-beam photoelectric sensors 22 to rotate. This allows the multiple rotating through-beam photoelectric sensors 22 to form an annular monitoring surface, monitoring the inner or outer annular surfaces of each component to be assembled in the pressure regulator 3. If a component experiences vertical displacement, it will obstruct the beam of the through-beam photoelectric sensor 22, thus achieving the monitoring effect and facilitating the correction of displacement during assembly. When assembling different components, it is necessary to adjust the shape of the multiple through-beam photoelectric sensors 22. When the diameter of the calibration monitoring ring is determined, the annular electronically controlled guide rail 16 is activated to drive the outer rotating ring 17 to rotate. The rotation of the outer rotating ring 17 will cause multiple arc-shaped calibration rods 18 to rotate as well. The change in the rotation angle of the arc-shaped calibration rods 18 will cause the calibration seat plate 21 to rotate on the pin shaft 19, thereby controlling the mutual convergence and expansion of multiple calibration seat plates 21, which in turn drives the mutual convergence and expansion of multiple through-beam photoelectric sensors 22, adjusting the annular diameter formed by multiple through-beam photoelectric sensors 22. This facilitates the correction and monitoring of the verticality of different components during the assembly process, avoiding component offset and non-perpendicularity of the components themselves during assembly.

[0037] The advantages mentioned above are as follows: the convergence and unfolding of multiple correction plates 21 can drive multiple through-beam photoelectric sensors 22 to move synchronously, and control and adjust the annular diameter formed by multiple through-beam photoelectric sensors 22. This facilitates the correction and monitoring of the verticality of different components during the assembly of the pressure regulator 3, and avoids the offset of each component of the pressure regulator 3 during the assembly process. This would prevent the valve core and compression spring in the core component of the pressure regulator 3 from being obstructed during vertical adjustment, thus ensuring the adjustment accuracy of the pressure regulator.

[0038] In use, the bottom inlet / outlet pipe housing of the pressure regulator 3 to be assembled is fitted and installed on the positioning groove of the positioning seat 2. Then, the assembly robotic arms 4 on both sides sequentially grasp and axially assemble the valve core, diaphragm, compression spring, and adjustment knob of the pressure regulator 3. The assembly robotic arms 4 perform positioning and assembly according to the program-set values. This is existing technology and will not be described in detail here. When assembling the vertical housing used to assemble the compression spring in the pressure sensor 3 with the bottom inlet / outlet pipe housing, the assembly robotic arms 4 fix the vertical housing to be assembled in position. Then, the screw cover 13 is put on the screw to be tightened, and the control ring 23 on the assembly table 1 is slowly rotated. The rotation of the control ring 23 will drive the adapter ring 5 to rotate. The rotation of the adapter ring 5 will drive the planetary gear ring 7 to rotate through multiple electric push rods 6. The rotation of the planetary gear ring 7 will drive the multiple rotating gears 8 on the inner side to rotate (rotation). The fixed platform 9 where gear 8 is located remains stationary under the fixed support of support rod 24 (and the fixed fixed platform 9 does not obstruct the light of the photoelectric sensor 22). The rotation of the self-rotating gear 8 will drive the drive wheel 10 to rotate through the rotating shaft, and then drive the driven wheel 12 to rotate through the transmission chain 11. The rotation of the driven wheel 12 will drive the screw cover 13 to rotate slowly together, so that the screw cover 13 can drive the screw to be tightened to rotate. During the process of the screw cover 13 driving the screw to tighten continuously, the screw cover 13 will slide in the sliding hole on the driven wheel 12 to prevent the screw cover 13 from detaching from the screw surface during the tightening process. In this way, the rotation of multiple self-rotating gears 8 can drive multiple screw covers 13 to rotate, and multiple fastening and sealing screws can be tightened axially and synchronously. This avoids the problem of slight misalignment between the upper and lower assembly shells of the pressure regulator 3 during the tightening process, and also makes the assembly efficiency of the pressure regulator 3 higher.

[0039] During assembly, multiple through-beam photoelectric sensors 22 are kept in the open state. The rotation of the revolving gear ring 7 drives the annular electronically controlled guide rail 16 to rotate via the support plate 15, which in turn drives the multiple through-beam photoelectric sensors 22 to rotate. This allows the multiple rotating through-beam photoelectric sensors 22 to form an annular monitoring surface, monitoring the inner or outer annular surfaces of each component to be assembled in the pressure regulator 3. If a component has a vertical offset, it will obstruct the beam of the through-beam photoelectric sensor 22, thus achieving the monitoring effect and facilitating the correction of offset during assembly. When assembling different components, it is necessary to adjust the diameter of the correction monitoring ring formed by the multiple through-beam photoelectric sensors 22. In this case, the annular electronically controlled guide rail 16 is activated to drive the outer rotating ring 17 to rotate. The rotation of the outer rotating ring 17 will cause multiple arc-shaped correction rods 18 to rotate as well. The change in the rotation angle of the arc-shaped correction rods 18 will cause the correction seat plate 21 to rotate on the pin 19. This controls the mutual convergence and expansion of multiple correction plates 21, which in turn drives the mutual convergence and expansion of multiple through-beam photoelectric sensors 22. Adjusting the annular diameter formed by the multiple through-beam photoelectric sensors 22 facilitates the correction and monitoring of the verticality of different components during assembly, preventing component misalignment and non-perpendicularity issues during assembly. The convergence and expansion of multiple correction plates 21 drive the synchronous movement of multiple through-beam photoelectric sensors 22, controlling and adjusting the annular diameter formed by the multiple through-beam photoelectric sensors 22. This facilitates the correction and monitoring of the verticality of different components during the assembly of the pressure regulator 3, preventing misalignment during the assembly of the pressure regulator 3 components. This avoids obstruction of the vertical adjustment movement of the valve core and compression spring in the core components of the pressure regulator 3, ensuring the adjustment accuracy of the pressure regulator.
