Description

Technical Field

[0001] The invention relates to the field of intelligent processing, and in particular to a grinding and polishing production line for automobile decorative strips. Background Art

[0002] With the gradual popularization of automobiles and people's in-depth understanding of automobiles, the practice of improving the grade of automobiles is increasingly recognized by automobile manufacturers and consumers. In order to achieve a good aesthetic effect, automobile decorative strips made of aluminum and its alloy materials are generally installed on the doors and windows of automobiles, thereby increasing the beauty of the side of the car body, highly consistent with the curvature of the car body, and durable and non-deformed. At the same time, it provides effective protection for the car body paint that is easily bumped when the door is opened and closed, and it needs to be polished with certain tools before installation before use.

[0003] The existing grinding and polishing process of automobile decorative strips adopts intelligent processing. Its production line includes industrial robots, unloading tables, sanding machines and polishing machines. The industrial robot clamps the automobile decorative strips to be polished on the unloading table through the clamping tooling, and then polishes them with the sanding machine in turn, and then polishes them with the polishing machine to complete the grinding and polishing process of the decorative strips. The loading and unloading of decorative strips are all through the unloading table. However, the existing production line has the following disadvantages during the processing:

[0004] The placement structure of the existing unloading tables is fixed, and can only place decorative strips of the same model or with similar curvatures. When processing decorative strips of different models, different types of unloading tables need to be replaced, which makes it inconvenient to replace the unloading tables and cannot be adapted to a variety of models. In addition, the existing unloading tables cannot re-inspect the decorative strips to see if they are qualified.

[0005] The existing polishing machine can only use a cloth wheel or a hemp wheel to polish the decorative strips. When fine polishing is required, it is necessary to replace the cloth wheel or the hemp wheel of another specification, resulting in insufficient polishing accuracy and low efficiency of the decorative strips. At the same time, when the existing polishing machine is polishing the decorative strips, the cloth wheel is in hard contact with the decorative strips, which may easily over-polish the decorative strips and cause damage to the decorative strips.

[0006] The existing belt sander can only use one belt to sand the decorative strips, and the belt needs to be replaced when fine sanding is required, resulting in insufficient sanding precision and low efficiency of the decorative strips. At the same time, the existing belt sander is prone to over-sanding the decorative strips due to the hard contact between the sanding belt and the decorative strips when sanding the decorative strips, causing damage to the decorative strips. In addition, the sanding belt breaks due to overheating or temperature imbalance of the sanding belt during long-term sanding. In order to protect the sanding belt and extend the service life of the sanding belt, some manufacturers apply soap on the sanding belt to extend the life of the sanding belt when sanding zinc alloy decorative strips. The reason is that zinc alloy itself has no sand holes, so soap will not affect the sanding belt sanding, and the sanding belt coated with soap can cool the sanding belt and disperse the concentrated heat of the sanding belt, thereby avoiding the sanding belt from breaking. However, this method can only be done by manually applying soap, which is time-consuming, labor-intensive and unsafe. Summary of the invention

[0007] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0008] The invention provides a production line for grinding and polishing automobile decorative strips. The rotary unloading table of the production line is adapted to decorative strips of different models and thicknesses by means of a movable unloading plate and a groove of adjustable width. The working area of ​​the unloading table is separated from the unloading area by arranging a rotating mechanism, so that workers do not need to enter the working area of ​​the industrial robot when loading and unloading materials, thereby ensuring the production safety of workers and improving production efficiency. At the same time, a re-inspection mechanism is arranged on the unloading table to remove decorative strips that do not meet the specifications. The polishing machine of the production line finely polishes the decorative strips by means of multiple groups of polishing mechanisms, avoids over-polishing of the decorative strips by means of a floating polishing component, conveniently adjusts the gap between the solid wax and the cloth wheel by means of a clamping hand wheel and a lateral adjustment component, the sanding belt machine automatically applies soap with the sanding belt by means of a sanding belt coating mechanism, thereby improving the service life of the sanding belt, finely polishes the decorative strips by means of multiple groups of sanding belt mechanisms, corrects the deviation of the sanding belt by means of a tensioning component, prevents over-polishing of the decorative strips by means of a floating polishing component, and avoids the influence of flying chips on the health of the operator by means of a flying chip collection component.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a production line for grinding and polishing automobile decorative strips, comprising a rotating unloading table for placing decorative strips, an industrial robot for clamping the decorative strips through a grinding and polishing fixture, a polishing machine for grinding the decorative strips, and a polishing machine for polishing the decorative strips, characterized in that: the rotating unloading table comprises a unloading rack and a unloading adjustment mechanism arranged on the unloading rack, the unloading adjustment mechanism comprises adjustment plates arranged at both ends of the unloading rack and at least two unloading plates mounted on the adjustment plate, the adjustment plate is provided with an adjustment slide, one end of the unloading plate corresponding to the adjustment slide is provided with a connecting piece movably connected to the adjustment slide, the unloading plate is freely movable in the adjustment slide through the connecting piece, a plurality of longitudinally equidistantly distributed adjustment clamps are provided on the unloading plate, and the adjustment clamp is provided with a groove for placing the decorative strips.

Adjustment plates are arranged at the upper and lower ends of the unloading rack, and adjustment slides are arranged on the adjustment plates, so that the unloading plate can move forward and backward in the adjustment slides through the connecting parts, so as to adapt to decorative strips with different curvatures. By arranging multiple adjustment clamps on the unloading plate , the adjusting fixture is provided with a groove for placing the decorative strips, so that the decorative strips can be stably fixed by the adjusting fixtures on each feed board. Specifically, when it is necessary to load the decorative strips of a certain model, it is only necessary to place the middle section of the decorative strip on the middle feed board, fix the mounting parts in the groove, and then push the feed board to move on the adjusting slide groove, thereby fixing the two ends of the decorative strip. When the feed board is fixed, it is only necessary to tighten the connecting parts to fix the feed board.
