The present invention relates to a monitoring and data storage system of the brake fluid injection equipment, and more particularly, having a monitoring and data storage system connected to the PLC side and the communication line in the brake fluid injection equipment, vehicle type, vacuum degree, injection pressure, By inputting and saving the status information of equipment such as injection time and injection volume, and monitoring the injection process and output status of equipment, various statistical analysis functions and working status of the vehicle can be checked. The present invention relates to a monitoring and data storage system for brake fluid injection equipment, which makes it possible to utilize the initial setting information of a vehicle stored in the system.

In general, the brake fluid injection device is a device that is disposed on the assembly line of the vehicle to inject oil after vacuum into the brake and clutch system of the vehicle.

The brake fluid injection equipment is composed of a base unit including a PLC, a console for measuring and setting various vacuum degrees, an injection gun for injection of brake fluid into a vehicle, and the like, as shown in FIG.

The base unit is composed of a main tank for storing the oil supplied from the drum, an auxiliary tank for supplying oil to the injection cylinder, a metering cylinder for metering brake fluid and a device for supplying dry air.

The console is composed of a vacuum pump for brakes, a TOP-OFF tank, and the like, and sensors for measuring vacuum pressure and injection pressure, etc. are installed. It is attached to the synchronous driving device which has a structure so that it may synchronize with a conveyor.

One injection gun is mounted on the console for each brake / clutch, and each injection gun can be operated independently and has an automatic clamp function.

Therefore, in the brake fluid injection device as described above, the injection cylinder is composed of one set, and the input / output pressure ratio is set to 1: 2.

The injection pressure at this time is set to about 5 kg / cm 2, the adjustment of the injection pressure can be set by adjusting the primary air pressure supplied to the cylinder.

That is, when the primary air pressure is 5 kg / cm 2, an injection pressure of about 10 kg / cm 2 can be obtained.

Brake fluid is injected into the brake fluid from the auxiliary tank when the cylinder is retracted, injected through the adapter when the cylinder is moved forward, and oil is transferred from the storage tank to the auxiliary tank when the cylinder is advanced.

When the brake fluid is used in a water-containing state, the performance of the brake system is degraded. Therefore, the pneumatic pressure supplied at the time of supplying the drum to the drum and at the top off after the injection of the brake oil to the reservoir is generally included. The supply of air is not necessary.

To this end, the brake fluid injection device is provided with a dry air supply device can supply dry air that does not contain moisture at the time of oil supply from the drum and the leveling of the reservoir.

The pneumatic pressure supplied at the leveling is to adjust the pressure at each console, and the pressure supplied to the drum is provided with a pressure reducing valve installed at the base unit to supply a pressure of 1 kg / cm 2 or less.

The control cabinet, which is integrated with the base unit, consists of a PLC and other electrical components, and displays the respective work processes in automatic and manual mode, and also displays the operation status and abnormality of each device installed in the equipment.

In addition, a switch is provided to perform each process in a manual state.

Therefore, after forming and checking at least two vacuum states, oil is injected, and the function of each brake fluid injection device will be described below.

1) Primary vacuum

The primary vacuum is a process of vacuuming the brake system, that is, the simulation line, through the adapter including the gun for a set time, and then removing the air therein.

2) Large leak check

The process proceeds to the same process as the primary vacuum and checks whether the vacuum degree set within the primary vacuum time is reached.

The set vacuum level at this time is about 4 Torr, and the set value can be changed by adjusting the ST1 value of the vacuum gauge controller installed at the front of the console.

When the set degree of vacuum is reached during the first vacuum time, the vacuum becomes OK and proceeds to the next step. When the set degree of vacuum is not reached, the large leakage lamp is turned on and an abnormal alarm signal is generated.

According to the setting of the leak bypass switch installed in the base unit, it is possible to determine the progress or abnormal termination of the next process according to the result of large leakage.

3) Small leak check

After the first vacuum, the process closes the vacuum valve of the console and checks whether the brake or clutch system is minutely leaked for a predetermined time.

The small leak check time is set to about 5 seconds and the limit vacuum is 3 Torr, which is set to ST2 of the vacuum gauge controller.

When the vacuum degree of the system falls below the vacuum degree set within the set time, it is determined as small leak.

In the above case, as in the case of large leak check, the subsequent process may be different when the small leak occurs according to the selection of the bypass switch.

In the small leak check process, a slight (typically in the 1 Torr range) vacuum drop is detected by the vacuum gauge controller to keep the vacuum level in the conduit and system even without leaking the system.

4) secondary vacuum

Secondary vacuum is a process of restoring the degree of vacuum lowered in the small leak check process. The second vacuum is a process of vacuuming the system by reopening the vacuum valve closed in the small leak check process for a predetermined time.

The secondary vacuum time is initially set to 30 seconds for the brake system without ABS and 20 seconds for the brake system without ABS. It is possible to modify this by modifying the PLC program.

5) injection

A process of injecting brake fluid into the system through an adapter for a predetermined time using an injection cylinder in a vacuum brake or clutch system.

When the set injection pressure is reached within the set limit injection time, it is pressurized for a predetermined time and the injection cylinder is retracted.

Pressurization time is set by ABS and CBS.

When the liquid is injected, the brake fluid flows from the main tank into the auxiliary tank, and after completion of the injection, the oil flows from the auxiliary tank into the injection cylinder when the injection cylinder is retracted.

When the injection pressure reaches the injection pressure set during injection, when the injection volume falls below the injection counter's set value, the lamp is turned on.

Each console is equipped with a switch that determines the injection pressure so that if the switch does not operate within the injection limit time, the lamp above the injection pressure will light.

The injection pressure switch is set at about 4.5 kg / cm 2 and can be changed.

After the injection cylinder is in place, the top off process is performed.

The top off process time is set to about 5 seconds, and the start of the top off proceeds to the injection completion stage.

The oil level in the reservoir tank at the top off can be varied by adjusting the nozzle length and the purge pressure of the adapter.

In the brake fluid injection equipment as described above, after setting and adjusting the vehicle type, vacuum degree, injection pressure, injection time, injection amount, etc. through the console, and performs the oil injection operation for the vehicle using the injection gun.

The state of the oil filling operation is performed while the operator checks the various gauges, sensors, lamps, etc. in the console.

However, when the vehicle is inspected or repaired after driving in the field, the initial setting information of the vehicle, for example, the brake system does not know the vacuum degree, injection pressure, injection time, injection amount, etc. When backtracking is performed to analyze the cause of the presence or absence, there is a problem that the work cannot be performed smoothly. Therefore, when checking and repairing a faulty vehicle, the state is returned to the optimal state as the initial state. There is a problem that cannot be restored.

Therefore, the present invention has been made in view of the above, and is connected to the communication line from the base unit PLC side of the brake fluid injection equipment to input the initial setting information of the vehicle such as vehicle type, vacuum degree, injection pressure, injection time, injection amount, etc. By providing a monitoring and data storage system that can be stored and used after receiving it, it is possible to monitor the injection process and output state of the brake fluid injection equipment, and accordingly, various statistical analysis functions and working status of the vehicle's condition can be monitored.
