The present invention relates to an automatic spray structure capable of preventing scratches and irregularities and preventing post-work contamination by automatically spraying soapy water onto an automobile body.

Conventionally, a work process of applying the body BODY, which is moved as a preliminary step for attaching the body side lamp to the vehicle, in a vehicle assembly process of the body BODY with soapy water through FIGS. 1 to 4. As you can see, soap and water before work is prepared (Fig. 1). After the car body is moved to the working position, bring the prepared soap and brush and apply to the car body (Fig. 2). Then, after applying soapy water to the car body cleans up soapy water and brushes and bring to the side lamp to be mounted on the car body (Fig. 3 and 4).

As such, in the related art, a process of applying soap on a car body has been manually performed.

Therefore, in the related art, a worker takes a lot of working time, there is a problem that the work efficiency is lowered, and there is a problem that the fatigue of the worker is also accumulated.

An object of the present invention is to improve the problems in the prior art as described above, to provide a new type of automatic spray structure that can improve the work efficiency by automatically performing the soap water coating operation proceeded by the conventional manual work Is in.

According to a preferred embodiment of the present invention for achieving the object as described above, the fixed body is installed on one side of the frame structure of the rectangular shape, the injection liquid is stored and stored on the vehicle body is moved through the injection nozzle An injection liquid reservoir equipped with a lever for injecting injection liquid into the; First and second limit switches including contact ends; A 5 / 2-way valve connected to the first and second limit switches through an air supply hose; An air cylinder connected to the 5 / 2-way valve through an air supply hose and provided with a rod that is moved back and forth by the pressure of the air supplied by the action of the 5 / 2-way valve; One side is coupled to both sides of the lever and the other side is coupled to the link device coupled to the rod of the air cylinder; including, wherein the first and second limit switch is moved to the vehicle body moving cart setting bracket An automatic spray structure is provided which is exposed so as to be able to sequentially contact.

Preferably, the injection liquid reservoir is characterized in that the cold water is installed in communication with the external cold water supply container and the hose is installed on one side of the rectangular frame structure.

Hereinafter, the automatic spray structure according to the present invention will be described in detail with reference to the accompanying drawings.

5 is a view schematically showing a pneumatic circuit diagram of an automatic spray structure according to the present invention.

Referring to FIG. 5, in the automatic spray structure according to the present invention, the pneumatic circuit portion includes first and second limit switches 62 and 64 and two 5 / 2-way valves including two contact terminal portions 62a and 64a. And an air cylinder 40.

Reference numerals L12, L13, L16, and L17 denote air supply hoses.

Referring to the operation of the pneumatic circuit diagram, first, when the contact terminal 62a of the first limit switch 62 is operated in contact with the setting bracket (see FIG. 13) of the bogie of the vehicle body to which the first limit switch 62 is moved, air is operated in the 5/2 way. Ascending to the valve 60, the raised air changes the valve chamber of the 5 / 2-way valve 60, the rod 42 of the air cylinder 40 is reversed.

Then, when the contact terminal 64a of the second limit switch 64 is operated in contact with the setting bracket (see FIG. 13) of the bogie of the vehicle body which is continuously moved, air is raised to the 5 / 2-way valve 60. As the air flows up, the rod 42 of the air cylinder 40 is advanced by changing the valve chamber of the 5 / 2-way valve 60. This results in one cycle stroke.
