A system and method for automatically assembling a water pump assembly

Abstract

The invention discloses a system and method for automatically assembling a water pump assembly. The system comprises a tool frame, an annular automatic belt conveying line, conveying trays, a control mechanism, a qualified product channel and a disqualified product channel. The conveying trays are arranged on the annular automatic belt conveying line. The qualified product channel and the disqualified product channel are arranged at the discharging end of the annular automatic belt conveying line. The annular automatic belt conveying line is arranged in the tool frame. The control mechanism is arranged outside the tool frame. A manual feeding station, an image detection station, an automatic gluing station, an automatic bearing pressing station, an automatic blank cap pressing station, an automatic water seal assembly pressing station, an automatic water seal assembly detection station, an automatic flange pressing station, an automatic impeller pressing station, an automatic dynamic verification station, an automatic laser marking station and a wiping and package detection station are sequentially arranged along the outer edge of the annular automatic belt conveying line. The system is simple in structure, low in production cost, high in work efficiency and small in worker workload.

Description

technical field [0001] The invention relates to the technical field of water pump assembly assembly, in particular to a system and method for automatically assembling a water pump assembly. Background technique [0002] like figure 1 As shown, the water pump assembly is mainly composed of pump body 1, shaft-connected bearing 2, flange 3, water seal assembly 4, impeller 5 and plug cover 6. 1. Flange 3 and shaft-connected bearing 2, moving ring of water seal assembly 4 and shaft-connected bearing 2, static ring of water seal assembly 4 and inner hole of pump body 1, plugging cover 6 and inner hole of pump body 1 The holes are all interference fits, so the assembly of the water pump assembly is press-fitted. [0003] like figure 2 As shown, the most commonly used common press assembly production line for water pump assembly is arranged in a U-shaped assembly line, and its process flow is as follows: [0004] Laser marking station OP10: put the pump body 1 on the positionin...

AI Technical Summary

Problems solved by technology

[0015] 1. Each station adopts manual loading and unloading, and manually operates the equipment. Therefore, the side of each equipment needs to be equipped with a feeding rack 7 for the parts of the corresponding station, and the feeding is relatively scattered;

[0016] 2. If image 3 As shown, the workpiece placement of each process needs to be changed according to the different press-fitting parts. The pump body of the pressurized water seal assembly and impeller process faces upward, and the pump body of other processes faces downward. Whether the workpiece is placed correctly depends entirely on the Manual control is prone to missing or wrong installation problems;

[0018] 4. The two-dimensional code engraved by the laser marking machine is used to trace the press-fit data of the water pump assembly (press bearing, press water seal assembly, press flange, press impeller) and dynamic calibration data, but The production line itself cannot automatically trace the data of each station. It can only be traced through a separate traceability system and a scanning gun. After the pump body 1 is engraved with a QR code, it needs to scan the engraved content with a scanning gun and upload it to the traceability system. And each process that needs to be traced needs to use a scanning gun to scan the QR code of the pump body 1 and the outer packaging box of other parts, and the assembly efficiency will be reduced by about 20%;

[0019] 5. The production line needs 5 operators in total according to the production beat, one operator is responsible for OP10, OP20, OP30 stations, another operator is responsible for OP40 and OP60 stations, and the third operator is responsible for OP60 and OP70 stations The fourth operator is in charge of OP80 and OP80 stations, the fifth operator is in charge of OP80100 and OP80110 stations, the labor cost is high;
