DETAILED DESCRIPTION

[0020] An automatic wax removal device for a vehicle body bottom panel, such as Figure 1-Figure 2 As shown, it includes an equipment body and an equipment pneumatic control system. The equipment body includes an aluminum profile frame 1.1, a nozzle mounting bracket 1.3, a nozzle 1.4, and a composite nozzle mounting bracket 1.5. The nozzle mounting bracket 1.3 and the composite nozzle mounting bracket 1.5 are arranged on the aluminum profile frame 1.1, and the nozzle 1.4 is arranged on the nozzle mounting bracket 1.3 and the composite nozzle mounting bracket 1.5. The nozzle 1.4 of the equipment body is connected to the equipment pneumatic control system.

[0021] The upper surface of the aluminum profile frame 1.1 is covered with a stainless steel cover plate 1.2.

[0022] The pneumatic control system of the equipment includes a first ball valve 2.1, a first pressure reducing valve 2.4, a first solenoid valve 2.5, a pressure switch 2.6, a second pressure reducing valve 2.7, and a second solenoid valve 2.8. The air source pipeline is connected to the nozzle 1.4 through the first ball valve 2.1, the first pressure reducing valve 2.4, the first solenoid valve 2.5, and the pressure switch 2.6 in sequence, and the second pressure reducing valve 2.7 and the second solenoid valve 2.8 are connected in parallel with the first pressure reducing valve 2.4 and the first solenoid valve 2.5.

[0023] Wherein, a filter 2.2 is arranged on the gas source pipeline.

[0024] Wherein, a flow meter 2.3 is arranged on the gas source pipeline.

[0025] The second ball valve 2.9 is connected in parallel with the first pressure reducing valve 2.4 and the first solenoid valve 2.5.

[0026] When the car body comes from the waxing room, the closed door of the waxing room opens, the car body stops at the waiting position, and the closed door of the waxing room closes.

[0027] If there is no car body at the chassis blowing station, the car body waiting for the station will be transported to the chassis blowing station. Figure 3 The pneumatic control system opens the second pressure reducing valve 2.7 and the second solenoid valve 2.8 to perform low-pressure air blowing, so that the nozzle 1.4 is kept in a blowing state to prevent the liquid wax dripping from the vehicle chassis from clogging the nozzle.

[0028] When the car body arrives at the chassis blowing station, the arrival signal is triggered. Figure 3 The pneumatic control system switches to the first pressure reducing valve 2.4 and the first solenoid valve 2.5 to open, the second pressure reducing valve 2.7 and the second solenoid valve 2.8 to close, and the gas pressure of the purge gas path is converted from low pressure gas to high pressure gas. Figure 1 The 1.4 nozzles in the middle blow the corresponding points on the car body. During the blowing process, Figure 1 The purging time of the nozzle in 1.4 is set and controlled by the control box. Figure 3 The second ball valve 2.9 is for debugging only.

[0029] After the purge is completed, Figure 3 The pneumatic control system switches to the second pressure reducing valve 2.7 and the second solenoid valve 2.8 to open, the first pressure reducing valve 2.4 and the first solenoid valve 2.5 to close, and the gas pressure of the purge gas path is converted from high pressure gas to low pressure gas. Figure 3 The second ball valve 2.9 is used for equipment commissioning.

[0030] The conveying system receives the signal and transports the car body to the end station.

[0031] After reaching the end station, Figure 3 The pneumatic control system shuts off the low-pressure gas, and a purge cycle ends.

[0032] The aluminum profile frame 1.1 is used to install the nozzle mounting bracket 1.3 and the composite nozzle mounting bracket 1.5, and the pneumatic nozzle 1.4 assembly is arranged on the nozzle mounting bracket 1.3 and the composite nozzle mounting bracket 1.5. In the case of not interfering with various types of nozzles, the upper surface of the aluminum profile frame is covered with a stainless steel cover plate 1.2, which also meets the requirements of convenient disassembly and maintenance and cleaning of residual wax liquid.

[0033] Among them, Figure 4 As shown, the nozzle mounting bracket 1.3 is a nozzle X\Y direction adjustment mounting plate 1.3.1 installed on the horizontal slide rail 1, and the nozzle 1.4 is arranged on the nozzle X\Y direction adjustment mounting plate 1.3.1.

[0034] Among them, Figure 5 As shown, the blowing nozzle X\Z direction adjustment mounting plate 1.3.2 is installed on the vertical slide rail 2, and the nozzle 1.4 is arranged on the blowing nozzle X\Z direction adjustment mounting plate 1.3.2.

[0035] Among them, Figure 6 As shown, the composite nozzle mounting bracket 1.5 is an X\Y direction rotating composite adjustment mounting plate 1.3.3 mounted on a horizontal slide rail.

[0036] The pneumatic nozzle assembly includes two structural forms: spatial angle nozzle and two-dimensional vertical nozzle. The installation results are shown in Figure 4 , Figure 5 , Figure 6 The nozzle position is fixed by a frame that is adjustable in the X / Y / Z directions so that the position can be adjusted according to production and quality conditions.

[0037] like Figure 3 As shown, the pneumatic control system is composed of the first ball valve 2.1, filter 2.2, flow meter 2.3, first pressure reducing valve 2.4, pneumatic solenoid valve 2.5, pressure switch 2.6, etc. The pneumatic plate is required to be a quick-detachable structure, and each nozzle is equipped with an independent speed regulating valve to individually control the purge flow at each point.

[0038] The filter 2.2 is installed in the main pipeline to remove oil, water and dust in the compressed air. The first pressure reducing valve 2.4 controls the pressure of the system. The pressure switch 2.6 is an air source pressure monitoring device to monitor the system pressure. It can alarm when the system pressure is insufficient. The flow meter 2.3 records the consumption of compressed air.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
