[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0014] like Figure 1-3 A paint surface separation device for automobile sheet metal spraying is shown, including a mounting frame 1 and a marking component installed on the mounting frame 1, the marking component including a screw 5, a spline 8 and a marking pen 10, both ends of the mounting frame 1 are fixedly installed with a fixing plate 2, and bearings at both ends of the screw 5 are installed with sliders 11, the slider 11 is movably connected to the fixing plate 2, the screw 5 is adapted to be installed with the spline 8, and a marking pen 10 is installed at the bottom of the spline 8, and a motor 3 is fixedly installed on the outer wall of one of the sliders 11, and the screw 5 is driven by the output end of the motor 3.

[0015] The outer walls of the two fixed plates 2 are provided with a slide groove 4, and the two sliders 11 are embedded in the slide groove 4. The motor 3 is arranged outside one of the fixed plates 2, and the outer wall of the motor 3 is fixedly connected to the slider 11, and the output end of the motor 3 is fixedly connected to the end of the screw 5. Baffles 6 are symmetrically arranged on both sides of the screw 5, and the ends of the baffles 6 are fixedly connected to the outer walls of the slider 11. The outer walls of the two baffles 6 are installed with cylinders 7, and the cylinders 7 are fixedly installed on the mounting frame 1, and the output ends of the cylinders 7 are fixedly connected to the baffles 6.

[0016] A fixed tube 9 is fixedly installed at the bottom of the spline 8, and a marker pen 10 is slidably installed inside the fixed tube 9. The marker pen 10 is an oil-based pen, which is easy to wipe off after being applied on the sheet metal. A lifting block is fixedly installed at the top of the marker pen 10, and sliding rods are symmetrically fixedly installed on both sides of the lifting block. The outer wall of the fixed tube 9 is symmetrically provided with lifting grooves, and the sliding rods are embedded in the lifting grooves. A spring 12 is installed inside the fixed tube 9, and the end of the spring 12 is fixedly connected to the lifting block at the top of the marker pen 10.

[0017] Embodiment: The mounting frame 1 is mounted above the sheet metal spraying station. The operator inputs the data into the external control terminal according to the area of ​​the sheet metal to be sprayed. Then the marking component is started. In the initial state, the tip of the marker pen 10 is in contact with the outer wall of the sheet metal. Then, according to the area data, the motor 3 is started to drive the screw 5 to rotate. The rotation of the screw 5 drives the spline 8 to move forward and backward on the screw 5. The cylinder 7 on the side of the baffle 6 pushes the baffle 6. The baffle 6 drives the screw 5 to move horizontally. The slider 11 moves horizontally inside the slide groove 4 of the fixed plate 2. At this time, the marker pen 10 draws a dividing line on the sheet metal.

[0018] Since the shape of the sheet metal is irregular, the marker pen 10 uses the ductility of the spring 12 to adapt to the irregularity of the sheet metal. The lifting block above the marker pen 10 moves up and down inside the fixed tube 9, and the slide rod moves up and down inside the lifting groove to adapt to the curvature change of the surface of the sheet metal.

[0019] By marking the components and accurately drawing lines on the sheet metal, the operator can use the marking lines as a reference when separating the paint surfaces later. The isolation cloth can be pasted according to the position of the marking lines to prevent the paint from being sprayed out of bounds and requiring re-sanding and re-painting.

[0020] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0021] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
