Description

[0035] Use this device to polish the shell 0. First, place the shell 0 on the moving table 302, and cooperate with the limiting effect of each group of limit blocks 304 to accurately place the shell 0 on the moving table 302. Then, drive a301 to control the moving table 302 to move right to the middle of the installation table 101. At this time, the three shells 0 are located directly behind the three groups of fixed modules. Then, the mobile module controls the moving seat 201 to move forward and backward;

[0036] When the movable seat 201 moves backward, first, the movable seat 201 drives the guide frame 704 to contact with the top block 705, and squeezes the push plate 703 to move upward, and the spring b706 is compressed, so that the push plate 703 can pass over the fixed module; then, the top shaft 203 is inserted into the space of the shell 0, and the top ball 205 is squeezed and retracted into the mounting plate 204 by the extension part of the shell 0, and the spring a206 is compressed until the shell 0 contacts the transition section of the top shaft 203 and is fixed on the top shaft 203, and the spring a206 clamps the top ball 205 into the mounting hole 001, thereby further fixing the shell 0, and at the same time, the shell The reaction force of the body 0 acts on the limit block 304, so that the sensor 306 can sense the force change of the limit block 304, and the control unit controls the pneumatic pump 305 and drives a301 to move the limit block 304 downward and into the movable table 302, and the movable table 302 is quickly moved to the left and retracted on the mounting table 102 without contacting the movable table 302. Therefore, the shell 0 is transferred to be fixed on the fixed module, and is transported backward by the fixed module to move below the sanding belt 404. After the top block 705 is separated from the guide frame 704, the push plate 703 is moved downward and reset by the spring b706;

[0037] When the three shells 0 are moved to the bottom of the frosting belt 404, the moving seat 201 stops moving, and the driving b402 controls the moving frame 401 to move downward, so that the frosting belt 404 contacts the shell 0, and then the driving c405 starts to control the frosting belt 404 to rotate to polish the shell 0. At the same time, the driving e605 controls the reciprocating screw b604 to rotate, controls the rack 603 to move back and forth, and controls the top shaft 203 to drive the upper shell 0 to flip back and forth, so that the frosting belt 404 contacts the outer surface of the shell 0 evenly; and the pressure roller 406 enables the frosting belt 404 to contact better, prevents the frosting belt 404 from being squeezed and deformed upward by the shell 0, and prevents the polishing quality from being reduced due to incomplete contact between the shell 0 and the frosting belt 404.

[0038] After finishing the polishing work of the shell 0, the moving seat 201 moves the fixed module and its upper shell 0 forward, and the guide frame 704 moves the top block 705 and the push plate 703 upward again, so that the push plate 703 can first pass over the mounting shell 202, and then the push plate 703 is moved down and reset by the spring b706. At this time, the forks of the push plate 703 are located in front of the top shaft 203 and the shell 0. Therefore, in the process of the fixed module continuing to move forward, the push plate 703 will resist the shell 0, so that the relative position of the shell 0 and the top shaft 203 changes, and the top ball 205 is squeezed by the mounting plate 204 and detached from the mounting hole 001, releasing the fixation of the shell 0. Then, the shell 0 will be completely detached from the top shaft 203 and fall freely, and will be collected uniformly by the collection frame located under the mounting table 101;

[0039] In particular, after the movable table 302 is moved back to the mounting table 102, the shell 0 can be placed on the movable table 302, and after the fixed module passes through the push plate 703 and completes the unloading of the polished shell 0, the movable table 302 can be controlled to move right to perform the next round of polishing of the shell 0, and so on.

[0040] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
