Description

Technical Field

[0001] The present invention relates to a valve production device, and more specifically, it relates to a PRV valve cover pressing device. Background Art

[0002] PRV valves are widely used in mechanical equipment. A PRV valve is assembled from a valve body and other valve fittings such as a valve cover. The current PRV valve assembly process is that the valve body and valve fittings are produced separately, and then a dedicated assembly line is set up for assembly. The process flow is long, the number of material transfers is large, and the floor space occupied is large, resulting in a long production cycle and low production efficiency. For this reason, some manufacturers have developed PRV valve assembly equipment to improve the assembly efficiency. For example, the utility model patent with the publication number CN211889808U discloses a PRV valve assembly machine for an automatic production line of a high-pressure airless spray gun pump body, including a fixed seat. A support disk is installed on the fixed seat. A PRV valve seat loading rack, an O-ring loading rack, a core chip loading rack, a detector, a gasket loading rack, and an unloading rack are installed on the fixed seat outside the support disk, and the PRV valve seat loading rack, the O-ring loading rack, the core chip loading rack, the detector, the gasket loading rack, and the unloading rack are annularly distributed. The beneficial effects of this utility model are as follows: The automatic assembly of the PRV valve is realized, the labor intensity is reduced, continuous operation can be carried out, and the work efficiency is improved; the setting of the alarm lamp is convenient for dispatching staff to repair and maintain the tooling in time when the tooling fails. However, this utility model adopts an annular layout to arrange the loading mechanisms of different components, which has certain requirements for the floor area. Summary of the Invention

[0003] The current PRV valve assembly process has a long process flow, a large number of material transfers, and a large floor space occupied, resulting in a long production cycle and low production efficiency. To overcome these defects, the present invention provides a PRV valve cover pressing device with high automation degree, which can shorten the production cycle and improve the production efficiency.

[0004] The technical solution of the present invention is: a PRV valve cover pressing device, which includes a valve cover feeding mechanism, a valve cover feeding track, a valve body feeding track, a valve cover picking manipulator, a valve cover detection mechanism, a pressing mechanism, a valve body feeding mechanism and a valve body cleaning mechanism. The valve cover feeding track and the valve body feeding track are located between the valve cover feeding mechanism and the valve body feeding mechanism, and the ends of the valve cover feeding track and the valve body feeding track overlap. The valve cover picking manipulator, the valve cover detection mechanism and the pressing mechanism are sequentially arranged along the material conveying path formed by the feeding track and the valve body feeding track. This PRV valve cover pressing device is divided into a valve body loading area, a detection area, a pressing area and a blanking area. The material conveying path formed by the valve cover feeding track and the valve body feeding track connects these areas in series. The valve cover picking manipulator transfers the valve covers on the valve cover feeding mechanism to the valve cover feeding track one by one, and conveys them to the detection area through the valve cover feeding track for detection at the valve cover detection mechanism. The qualified valve covers are continuously conveyed to the pressing area. At the same time, the valve body feeding mechanism inputs the valve bodies at the other end, which are first sent to the valve body cleaning mechanism through the valve body feeding track for internal cleaning, and then sent to the pressing area. The valve body and the valve cover are overlapped in position, and the assembly is completed through the pressing mechanism to form a combined body, and then the combined body is output through other manipulators. Through this PRV valve cover pressing device, the detection process of the valve cover and the assembly process of the valve cover and the valve body can be integrated on the same device, which can reduce the number of component turnovers, reduce the storage, facilities and labor requirements generated by material flow, shorten the assembly process of the PRV valve, thereby shortening the production cycle and improving production efficiency.

The screw driver provides power for the valve cover tray to move on the feeding guide rail. The valve cover tray receives the valve cover positioning plate transferred from the outside at one end of the feeding guide rail. The valve covers to be installed are neatly placed on the valve cover positioning plate. After the valve cover tray moves to the other end of the feeding guide rail, the valve cover picking manipulator starts to load the valve covers.

[0030] The working method of this PRV valve cover pressing equipment is as follows:

[0031] Step 1. Neatly place the valve cover 33 composed of a cover body, a cover plate, and a spring to be installed on the valve cover positioning plate. The valve cover 33 corresponds to the valve cover positioning grooves 8 one by one. Under the control of the PLC, the screw driver 9 drives the valve cover tray 6 to the starting end of the feeding guide rail 4, and transfers the valve cover positioning plate 7 to the valve cover tray 6 and positions it; at the same time, the servo transplanting module drives the valve body slide 26 to the starting end of the valve body feeding track 25, and the valve body 34 is placed on the valve body positioning mold on the valve body slide 26 manually or by a manipulator.

[0032] Step 2. Under the control of the PLC, the valve cover tray 6 moves to the terminal of the feeding guide rail 4, and the valve cover picking manipulator 3 starts to load the valve cover 33; at the same time, the valve body slide 26 carries the valve body 34 to the valve body cleaning mechanism and stops. The piston rod of the intake pipe lifting cylinder 36 extends and descends, and the connecting plate at the end of the piston rod of the intake pipe lifting cylinder 36 presses the valve body 34. At the same time, it also drives the intake pipe pushing cylinder 37 and the intake plug 38 to descend in place. The exhaust pipe lifting cylinder 40 drives the exhaust pipe 39 to rise, and the exhaust plug passes through the through hole on the valve body positioning plate 35 and inserts into the valve cover hole position of the valve body 34. Subsequently, the air pipe pushing cylinder 37 starts to push the intake plug 38 to feed and insert into the input port of the valve body 34. In this way, the intake plug 38 and the exhaust plug seal the main air flow holes on the valve body 34, establishing an air flow channel for the internal cavity of the valve body 34; then, the flexible intake pipe is introduced with compressed air and discharged from the exhaust pipe 39, so as to clean the internal cavity of the valve body 34 with air flow to ensure the internal cleanliness after the valve cover 33 and the valve body 34 are assembled.

[0033] Step 3. Under the control of the PLC, the valve cover slide drives the screw 15 to drive the valve cover slide 14 to move along the valve cover feeding track 2 to below the detection lens 18. The valve cover picking manipulator 3 places the valve cover 33 grabbed from the valve cover tray 6 on the valve cover slide 14 and positions it. The valve cover 33 is photographed by the detection lens 18, and then a signal is generated and transmitted to the PLC. According to the detection result, the good products and defective products are judged. The good products are continuously conveyed by the valve cover slide 14, while the defective products are picked out by the defective product picking gripper. The picked defective products are released by the defective product clamping jaws, fall onto the outflow slide 23, and then slide down to the conveyor belt 24 for fixed-point collection.

[0034] Step 4. Under the control of the PLC, the intake pipe pushing cylinder 37, the intake pipe lifting cylinder 36, and the exhaust pipe lifting cylinder 40 are reset in sequence. Then, the valve cover slide 14 and the valve body slide 26 respectively carry the valve cover 33 and the valve body 34 to meet at the press-fitting mechanism. At this time, the valve cover slide 14 is located between the valve body slide 26 and the valve body positioning plate 35, and the valve cover hole position of the valve body 34 overlaps with the position of the valve cover 33.

[0035] Step 5. Under the control of the PLC, the press-fitting cylinder 16 drives the pressure plate 17 to apply downward force and pressurize the valve body 34. After the valve body 34 and the valve body positioning plate 35 are pressurized, they overcome the elastic force of the compression spring 42 and descend. The position of the valve body 34 is lowered until the valve cover 33 passes through the through hole on the valve body positioning plate 35 and is aligned and pressed against the valve cover hole position of the valve body 34, completing the assembly of the valve cover 33 on the valve body 34.

[0036] Step 6. Under the control of the PLC, the combined body jaw 31 descends to the position of the valve cover and valve body combined body under the drive of the combined body lifting cylinder 30, clamps the valve cover and valve body combined body, and then the rotating cylinder 32 is started to turn over the valve cover and valve body combined body, which is grabbed by the blanking manipulator.
