Description

Technical Field

[0001] The utility model relates to the technical field of paint surface repair, and particularly relates to an automatic paint filling device which is convenient for positioning. Background Art

[0002] With the rapid development of modern manufacturing industry, especially in the fields of automobiles, aerospace, construction, and furniture, the demand for paint surface repair technology is increasing day by day. Paint surface repair not only concerns the appearance quality of products, but also directly affects the durability and service life of products. However, the traditional paint surface repair process often relies on manual operation, which is not only inefficient, but also has problems such as inaccurate positioning and uneven repair effects. In order to overcome the above challenges, automatic paint filling devices have emerged. This kind of device combines modern robot technology, precise control system and intelligent software to achieve efficient, uniform and precise painting operations. The automatic paint filling device not only improves production efficiency, but also significantly improves the repair quality and safety.

[0003] When the existing automatic paint filling device is in use, it lacks an automatic detection mechanism and cannot automatically adjust the position of the paint filling mechanism according to the actual situation of the paint surface defect.

[0004] For example, an automatic paint filling machine disclosed in the patent with the publication number CN203899837U. When the automatic paint filling machine of this patent is in use, the air cylinder acts to drive the ejector rod to advance forward. During the forward advancement of the ejector rod, on the one hand, through the cooperation of its curved surface protrusion and the slide rail pulley, the slide rail is made to approach the valve, and the end of the slide rail meshing with the valve core can drive the valve core to rotate and open the valve, so that the paint in the paint can enters the paint box and reaches the brush head through the paint pipe, realizing automatic paint filling; on the other hand, the ejector rod simultaneously drives the connecting piece, that is, each guide rod, to advance forward, so that the brush head reaches the paint surface to be repaired of the part for automatic smearing work. When the work is completed, the air cylinder retracts, and the return spring drives the slide rail to return to its position, closing the valve, so that the paint can cannot supply paint to the paint box, which can effectively avoid paint waste and paint solidification.

[0005] Although the above automatic paint filling machine realizes efficient paint supply and painting functions in design, there are still some deficiencies in the detection and positioning of paint surface defects. Due to the lack of an automatic detection mechanism, the paint filling machine cannot automatically adjust the position of the paint filling head according to the actual situation of the paint surface defect to achieve the best paint filling effect, which requires the operator to accurately mark the area to be painted in advance, or continuously manually adjust the position of the paint filling head during the paint filling process, increasing the complexity and time cost of the operation.

[0006] Therefore, it is necessary to invent an automatic paint filling device which is convenient for positioning to solve the above problems. Summary of the Utility Model

[0036] Working principle of the present utility model:

[0037] Refer to the attached Figures 1-5 drawing. When using the present utility model, first open the operation door 15, place the workpiece to be repainted at a predetermined position on the top of the workbench 1, and then close the operation door 15 to isolate the operation space from the external environment;

[0038] Start the entire paint replenishment system through the control panel 13, including the longitudinal linear module 3, the transverse linear module 5, the electric push rod 6, the DD direct drive motor 8, the 3D deflection camera 10, and the electric paint spray gun 12.

[0041] After all the touch-up painting operations are completed, start the air purifier 17 through the control panel 13, extract the air inside the isolation hood 14 through the air duct 18 and purify it to reduce the residue of harmful substances. After the air purification is completed, open the operation door 15 and safely remove the workpiece after touch-up painting from the workbench 1.
