This process not only consumes a lot of physical strength, but also has a limited number of items to be moved at a time. The frequent back-and-forth operations take a very long time, making it difficult to achieve efficient and continuous production. Summary of the Invention

[0004] The purpose of the present invention is to provide an oxidation electrophoresis production equipment and method for aluminum processing.

[0013] S1: Install the aluminum material on the fixed plate, and then push the fixed plate. At this time, the pulley will move on the support plate, and then it will slide into the second slide groove. After the pulley slides into the second slide groove, the limit plate will fall into the first slide groove, and then start the motor on the motor frame. At this time, as the motor rotates, the shaft will also rotate. When the shaft rotates, the sprocket will also rotate. Then the sprocket will run with the hinge. When the hinge moves, the fixed box will move with it, and then the triangle plate on the skateboard will contact the limit plate. After the limit plate contacts the triangle plate, the movement of the hinge will make the triangle plate move downward. At this time, the triangle plate will also move with the skateboard. When the skateboard moves, the spring will be squeezed downward. As the spring contracts, it can assist the triangle plate to pass through the limit plate, and then the limit plate The positioning plate will be stuck between the sliding rod and the triangular plate, and the operation of the hinge will lead the limit plate to move with it.

At this time, the fixed plate will lead the aluminum into the drying box, and the motor can be stopped at this time, thereby achieving the effect of complete feeding. After the drying is completed, the motor will be started again. At this time, the sliding rod will continue to lead the fixed plate and the aluminum out of the drying box. When the triangular plate reaches the end, it will contact the support plate again. After contact, the triangular plate will slide down with the slide again and be pressed down by the spring. Then the limit plate will be separated from the sliding rod and the triangular plate, thereby stopping the restriction on it, thereby achieving the effect of automatic loading and unloading.

During the circulation, it will pass through the heating rod, and the heating rod will heat the air. At the beginning of heating, the direction of the hot air can also be changed by adjusting the angle of the adjustable air regulating plate to reach the contact area between the hot air and the aluminum.

[0015] The present invention has the following beneficial effects:

[0016] When the cam is in contact with the support plate, the spring is pressed downward, and the contraction of the spring can assist the triangular plate to pass through the limiting plate, and then the limiting plate will be stuck between the slide bar and the triangular plate, and at the same time, the operation of the 211 hinge will bring The limit plate will move accordingly, and the limit plate will move along the first slide with the fixed plate, and the pulley will also move in the second slide. The fixed plate will bring the aluminum into the drying box, and the motor can be stopped at this time, thus achieving the effect of complete feeding. After the drying is completed, the motor will be started again. At this time, the slide bar will continue to slide the fixed plate and the aluminum out of the drying box. When the triangle plate reaches the end, it will contact the support plate again. After contact, the triangle plate will slide down with the slide plate again and be pressed down by the spring. Then the limit plate will be separated from the slide bar and the triangle plate, thereby stopping the restriction on it, thereby achieving the effect of automatic loading and unloading, so that during the production process, the aluminum can enter the drying box quickly and orderly without manual intervention to complete the processing, which greatly shortens the production cycle and effectively avoids the time loss and manpower waste caused by manual handling.

[0017] 2. The present invention sets a drying mechanism. After the aluminum material enters the drying box, the heating rod and the fan are started. After the fan is started, the air in the drying box will circulate in the circulation pipe. During the circulation, the air will pass through the heating rod, and the heating rod will heat the air. At the beginning of heating, the direction of the hot air can also be changed by adjusting the angle of the adjustable air regulating plate to reach the contact area between the hot air and the aluminum material, thereby ensuring that the electrophoretic coating is uniformly cured during the drying process, reducing coating defects caused by uneven temperature, such as local cracking, discoloration and other problems, and improving the product yield.

After the pulley 214 slides into the second slide groove 212, the limit plate 2117 will fall into the first slide groove 211, and then start the motor 219 on the motor frame 218. At this time, as the motor 219 rotates, the shaft 215 will also rotate. When the shaft 215 rotates, the sprocket 216 will also rotate. Then the sprocket 216 will bring the hinge 2 17 operates accordingly, and when the hinge 217 moves, the fixed box 2110 will move accordingly, and then the triangular plate 2113 on the slide 2111 will contact the limit plate 2117. After the limit plate 2117 contacts the triangular plate 2113, the movement of the hinge 217 will cause the triangular plate 2113 to move downward. At this time, the triangular plate 2113 will also move with the slide 2111. When the slide 2111 moves, the spring 2112 will be squeezed downward, and as the spring 2112 contracts, it can assist the triangular plate 2113 to pass through the limit The limiting plate 2117 is then stuck between the slide bar 2114 and the triangular plate 2113, and the limiting plate 2117 is moved along with it by the operation of the hinge 217 211. At this time, the limiting plate 2117 will move along the slide 1 211 with the fixed plate 213, and the pulley 214 will also move in the slide 212.
