Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive air conditioning pipe manufacturing, and is a workpiece O-ring spraying equipment that combines an oil injection mechanism with an automated control system. Background Technology
[0002] In automotive air conditioning systems, the air conditioning piping is a crucial component connecting the entire thermal management cycle. To better control the operation of the thermal management system, numerous sensors are used in the air conditioning pipes or integrated modules. With the increasing prevalence of electric vehicles, the thermal management system's requirements for monitoring each loop in the air conditioning piping are rising, leading to an increase in the number of sensors. Sensors are sealed to the air conditioning pipes using O-rings. These O-rings require even application of lubricant for proper installation and to prevent leaks. The increased number of sensors means an increased risk of leaks. Leaks of refrigerant in the air conditioning pipes can lead to reduced efficiency and even failure of the thermal management system, and the leaked refrigerant can also pollute the ambient air. To reduce the instability caused by manual lubrication, an automated spraying device is needed to lubricate the O-rings. This not only ensures consistent lubrication but also reduces labor costs. Summary of the Invention
[0003] The purpose of this invention is to provide a workpiece O-ring spraying device that uses a simple structure to complete the O-ring spraying process, ensuring uniform and complete oil coating.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a workpiece O-ring spraying device, the device comprising an oil spraying cavity, an oil pump, and an oil tank, wherein the oil pump, oil tank, and oil spraying cavity are connected by an oil spraying circuit, and a control unit is provided on the oil spraying circuit for controlling the operation of the oil pump; characterized in that an oil spraying cavity cover is provided at the top of the oil spraying cavity, and a workpiece placement port is provided on the oil spraying cavity cover for placing the workpiece with the O-ring to be sprayed; oil spraying ports are provided on both sides of the spraying cavity, and a photoelectric sensor is also provided inside the spraying cavity for detecting whether the workpiece to be sprayed is in place; and an oil-saving seat is provided at the bottom of the oil spraying cavity for collecting the sprayed oil drippings.
[0005] Furthermore, an O-ring is provided between the fuel-saving seat and the lower inner side of the fuel injection cavity, and an O-ring is provided between the fuel injection cavity cover and the upper inner side of the fuel injection cavity.
[0006] Furthermore, the bottom of the fuel-saving seat is connected to the fuel tank via a pipeline, allowing excess fuel to flow back into the fuel tank.
[0007] Furthermore, the control unit includes a PLC. The first input terminal of the PLC is connected to a photoelectric sensor, and the output terminal of the PLC is connected to an oil pump. When the photoelectric sensor detects that the workpiece to be coated is in place, it sends a signal to the PLC. The PLC controls the oil pump to work and sprays oil from the spray nozzle to coat the O-ring surface on the workpiece.
[0008] Furthermore, the device also includes a fuel injection start switch, which is connected to the second input terminal of the PLC for manual control of fuel injection.
[0009] Furthermore, the fuel injection circuit is also equipped with a fuel quantity adjustment switch for adjusting the fuel quantity.
[0010] This invention relates to a workpiece O-ring spraying equipment. A control unit controls an oil pump to deliver oil from the tank to the spray nozzle, which then sprays oil onto the O-ring surface of the workpiece placed in the spraying cavity. The advantage of this invention is that it improves production speed while ensuring quality and safe production. Attached Figure Description

[0016] This utility model relates to a workpiece O-ring spraying equipment, which mainly includes an oil spraying cavity and an automated control system. The main focus of this utility model is the structure of its oil spraying cavity.
[0017] As shown in the figure, a workpiece O-ring spraying equipment includes an oil spraying cavity 1, an oil pump 11, and an oil tank (not shown in the figure). The oil pump 11, the oil tank, and the oil spraying cavity 1 are connected by an oil spraying circuit 2. The oil spraying circuit 2 is equipped with a control unit 4, which is used to control the operation of the oil pump 11. The feature is that the top of the spraying cavity 1 is provided with a spraying cavity cover 6, and the spraying cavity cover 6 is provided with a workpiece placement port for placing the workpiece 7 with the O-ring 10 to be sprayed; the spraying cavity 1 is provided with spraying ports 9 on both sides, and the positions of the spraying ports 9 correspond to the positions of the O-ring 10 to be sprayed on the workpiece 7, for high-pressure spraying of oil on the O-ring 10 to be sprayed; the spraying cavity 1 is also provided with a photoelectric sensor (not shown in the figure) corresponding to the workpiece 7, and the photoelectric sensor is matched with the position of the workpiece placement port to detect whether the workpiece 7 is in place; the bottom of the spraying cavity 1 is provided with a fuel-saving seat 5 for collecting the sprayed oil dripping, and the bottom of the fuel-saving seat is connected to the oil tank through a pipeline so that the excess oil flows back to the oil tank.
[0018] The control unit includes a PLC 12. The first input terminal of the PLC is connected to a photoelectric sensor, and the output terminal is connected to an oil pump 11. When the photoelectric sensor detects that the workpiece is in place, it sends a signal to the PLC, which then controls the oil pump to operate, spraying oil from the spray nozzle 9 onto the surface of the O-ring 10 to be coated on the workpiece. The device also includes an oil spray start switch 13, which is connected to the second input terminal of the PLC for manual control of the oil spraying. An oil volume adjustment switch 3 is also provided on the oil spraying circuit 2 to adjust the oil volume.
[0019] The workflow of this utility model is as follows:
[0020] The workpiece is placed into the spraying cavity 1. The photoelectric sensor in the spraying cavity 1 detects that the workpiece has been in place and inputs the workpiece arrival signal to the PLC. The PLC controls the oil pump to work and the spray nozzle starts spraying oil.
[0021] The oil pump pumps the oil in the oil tank through the oil injection circuit to the oil injection cavity, and the oil is evenly sprayed onto the surface of the O-ring to be coated on the workpiece through the oil injection nozzle;
[0022] The PLC program will stop the oil pump after the fixed oil injection time is reached, completing one work cycle. The workpiece will then be removed for the next process.
[0023] In manual control, the start button can be pressed manually, and the PLC will control the oil pump to start working.
