Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a multi-process automatic processing, assembly and inspection system. Background Technology

[0002] With increasing mechanization and specialization, a product often requires multiple steps in industrial processing and manufacturing to complete. These steps often involve low levels of automation, high manual labor intensity, and numerous transport and transfer links between different processes. To improve product quality and production efficiency, researchers have been dedicated to developing stable and efficient automated processing, assembly, and testing systems.

[0003] The existing assembly process for end cap products is as follows: the required parts are transported to the assembly site; the oil injection holes of the end caps are manually inspected using a high-pressure air gun; the sliding bearings are manually pressed into place using a press; the oil seals and large-end bearings are manually hammered into place using a hammer; the locating pin holes for the large-end bearings are manually drilled using a drilling machine; the elastic locating pins for the large-end bearings are manually hammered into place; the locating pin holes for the self-lubricating bearings are manually drilled using a drilling machine; and the elastic locating pins for the self-lubricating bearings are manually hammered into place. The grease fittings are also manually installed. All of the above processes are completed manually in combination with presses and drilling machines. The conditions are rudimentary, the process is complex, errors are prone to occur, production efficiency is low, product quality is difficult to guarantee, and the labor intensity of the workers is high.

[0004] For example, a Chinese utility model patent with publication number CN209773892U discloses an automated oil pump end cap pin assembly device, which includes a frame, an end cap feeding mechanism, a pin feeding mechanism, and a pin pressing mechanism. It integrates the end cap feeding mechanism, the pin feeding mechanism, the pin pressing mechanism, multiple processing stations set on the frame, and an end cap station transfer mechanism, enabling automated pin pressing of the oil pump end cap. However, this technical solution only automates the pin pressing of the end cap; processes such as inspection, drilling, lubrication, and deburring still require separate operations, affecting assembly efficiency. Summary of the Invention

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0055] In this embodiment, the multi-process automated machining, assembly, and inspection system is more specifically an automated machining, assembly, and inspection line for end caps, such as motor end caps. It should be noted that the multi-process automated machining, assembly, and inspection system can also be an automated machining, assembly, and inspection line for other products. Any multi-process automated machining, assembly, and inspection involving operations such as press-fitting, inspection, drilling, drill bit lubrication, installation of elastic locating pins, deburring, and product lubrication is applicable to the automated machining, assembly, and inspection system described in this application and is considered to be within the scope of protection of this application.

[0056] This embodiment uses the processing, assembly, and inspection system for end cap products as an example.

[0057] like Figure 1 The diagram shows an overall schematic of a multi-process automated machining, assembly, and inspection system, including a loop-type speed-multiplying chain 1, a bearing feeding system 2, a six-axis loading robot 3, an oil seal feeding system 4, a vibratory feeder 5, a fully automatic press-fitting station 6, a fully automatic drilling and oil nozzle tightening station 7, a fully automatic press-fitting elastic positioning pin station 8, and a fully automatic deburring, lubrication, and press-fitting side-end elastic positioning pin station 9.

[0058] The bearing feeding system 2, the six-axis loading robot 3, the oil seal feeding system 4, and the vibratory feeder 5 are arranged sequentially along the conveying direction of the loop-type speed chain 1 on one side of the loop-type speed chain 1.

[0060] The processing includes various specifications of bearings, oil seals, grease fittings, and pins. The tray and unassembled end caps are placed on a loop-type double-speed chain 1. Bearings and oil seals are stored in bearing feeding system 2 and oil seal feeding system 4, respectively. A six-axis loading robot 3 picks up bearings and oil seals from bearing feeding system 2 and oil seal feeding system 4 and delivers them to the assembly position. A vibratory feeder 5 is used for loading grease fittings and pins. Fully automatic pressing stations 6, 7, 8, and 9 sequentially perform pressing of the end caps, grease fitting, pressing of elastic locating pins, deburring and lubrication, and pressing of side-end elastic locating pins during the end cap conveying process, thus completing the fully automatic processing of the end caps.

[0061] Specifically, such as Figure 2 As shown, the spiral-shaped double-speed chain 1 includes a chain body 12 and a double-speed chain lateral movement mechanism 11. The chain body 12 consists of two parallel double-speed chains. The chain body 12 is driven by the double-speed chain lateral movement mechanism 11 to enable the chain body 12 to move laterally to convey materials. The double-speed chain lateral movement mechanism 11 includes a lateral sliding module 111 and a sliding module driver 112. The sliding module driver 112 drives and connects to the lateral sliding module 111, and the lateral sliding module 111 is driven by the sliding module driver 112 to drive the chain body 12 to achieve conveying.

[0062] During processing, the pallet and the unassembled end cap are first placed on the chain body 12, and the chain body 12 is driven forward by the double-speed chain traverse mechanism 11.

[0063] Next, the six-axis loading robot 3 picks up the bearings and oil seals from the bearing feeding system 2 and the oil seal feeding system 4 respectively and places them in the designated installation positions.

It also includes a dispensing module 23, which is used to dispense the bearings. The output end of the pushing cylinder 22 faces the dispensing module 23 and the feeding bracket, and is used to push the various bearings to the feeding position after dispensing. The bearing dispensing module is existing technology and will not be described in detail here.

[0065] like Figure 4As shown, the six-axis loading robot 3 includes a six-axis robot body 31 and grippers 32. The six-axis robot body 31 is connected to the grippers 32 via a robotic arm transmission. The grippers 32 include an electric cylinder 321 and fingertips 322. The electric cylinder 321 is connected to the fingertips 322 via a transmission connection. Electricity is used to drive the reciprocating motion of the fingertips 322 to achieve material gripping. The fingertips 322 are used to grip various types of bearings and oil seals. It should be noted that the robot, as a workpiece gripping mechanism, can adopt existing technology, and its working principle will not be elaborated here.

[0066] like Figure 5 As shown, the oil seal feeding system 4 includes a first frame 41, a feeding mechanism 42, and a drive mechanism 43. The feeding mechanism 42 and the drive mechanism 43 are mounted on the first frame 41. The drive mechanism 43 is connected to the feeding mechanism 42 in a transmission manner. The feeding mechanism 42 is used for feeding oil seals and contains a push rod that can move up and down.

[0067] like Figure 6 As shown, the vibratory feeder 5 includes several sets of vibratory feeder bodies and screening mechanisms 52. The screening mechanism 52 is located beside the vibratory feeder body and is used for screening and feeding materials. It should be noted that both the vibratory feeder body and the screening mechanism 52 are prior art and will not be described in detail here.

The lifting and positioning mechanism 64 is used to lift and position the pallet before pressing, and the oil passage detection mechanism 65 is used to detect the oil passage of the end cap.

The upper drilling mechanism 72, the lower drilling mechanism 73, and the side drilling mechanism 74 simultaneously drill holes in the end cap, and the oil nozzle tightening mechanism 75 tightens the oil nozzles at the same time as drilling.

[0073] Specifically, the upper drilling mechanism 72 is driven by a motor-screw structure and is used for drilling holes in the bearing at the upper end of the end cap. It includes an upper multi-spindle drill 721, an upper multi-spindle drill longitudinal movement drive 722, and an upper multi-spindle drill dust extraction module 723. The upper multi-spindle drill longitudinal movement drive 722 is connected to the upper multi-spindle drill 721, driving the upper multi-spindle drill 721 to move longitudinally and drill. The upper multi-spindle drill dust extraction module 723 is positioned beside a preset drilling position for dust extraction during the drilling process. The lower drilling mechanism 73 is driven by a motor-screw structure and is used for drilling holes in the bearing at the lower end of the end cap. It includes a lower multi-spindle drill 731 and a lower multi-spindle drill longitudinal movement drive 732.

The oil nozzle tightening up and down drive 751 is connected to the oil nozzle tightening gun 752. It should be noted that each drive is existing technology and can be a motor, electric cylinder, etc., which will not be described in detail here.

[0074] The fully automatic drilling and oil nozzle tightening station 7 also includes an automatic lubrication system 76 installed on the third frame 71. The fully automatic lubrication system 76 includes an automatic lubrication rotating mechanism 761 and a lubrication oil pan 762. The automatic lubrication rotating mechanism 761 is driven and connected to the lubrication oil pan 762. The automatic lubrication rotating mechanism 761 is used to rotate the lubrication oil pan 762, which is used for lubricating the drill bits for upper drilling, lower drilling, and side drilling. It should be noted that the automatic lubrication rotating mechanism 761 and the lubrication oil pan 762 are existing technologies and will not be described in detail here.

[0075] In addition, the pallet is also lifted and positioned by the lifting and positioning mechanism 64 before drilling.

[0076] Next, the loop-type double-speed chain 1 will transport the end cap with the drilled hole and screwed on the oil nozzle to the fully automatic press-fitting elastic positioning pin station 8 for the pressing operation.

[0077] like Figure 9 As shown, the fully automatic press-fitting elastic locating pin station 8 includes a fourth frame 81 and a pressing mechanism 82 and a flipping mechanism 83 mounted on the fourth frame 81. The pressing mechanism 82 is used to press the elastic locating pins on the upper and lower surfaces of the end cap, and the flipping mechanism 83 is used to flip the end cap. The end cap with holes drilled and oil nozzles screwed on is conveyed to the fully automatic press-fitting elastic locating pin station 8, where the pressing mechanism 82 performs the pressing operation, and then the flipping mechanism 83 flips the end cap, and the pressing mechanism 82 performs the reverse pressing operation.
