Description

Technical Field

[0001] The present application relates to the technical field of automobile sign production and processing, and in particular to an automobile sign polishing device. Background Art

[0002] As people's living standards continue to improve, the use of cars is becoming increasingly popular. Car signs are an important symbol of the car and have a significant impact on the car brand. Car signs undergo multiple processing steps during production. In the existing production process, after the car sign is initially formed, burrs will remain on the surface of the car sign. These burrs need to be polished using a grinding device to ensure the flatness and smoothness of the car sign surface, thereby ensuring the production quality of the car sign.

[0003] An existing grinding device includes a box body, a supporting foot welded to the bottom of the box body, four fixing rods welded to one side of the top of the box body, a supporting platform fixedly installed on the top of the four fixing rods, a rubber pad fixedly installed on the top of the support platform, a driving motor box fixedly installed on the rubber pad, a driving motor fixedly installed in the driving motor box, and the output shaft of the driving motor is axially connected to one end of the rotating rod, and the other end of the rotating rod is adapted to be installed with a grinding sheet, a supporting rod is welded near the side of the top of the box body, a grinding platform is adjustably connected to the supporting rod, and a positioning mechanism for fixing the car sign is provided on the grinding platform.

[0004] When the above-mentioned grinding device is used to grind the car sign, after the grinding sheet has finished grinding one side of the car sign, it is necessary to release the positioning of the car sign by the positioning mechanism, and the operator manually turns the car sign over, and then uses the positioning mechanism to reposition the car sign, and then grinds the other side of the car sign. As a result, the operation steps for grinding the car sign are relatively cumbersome, which easily affects the grinding efficiency of the car sign. Utility Model Content

[0043] Reference Figure 3 and Figure 4After the positioning of the car sign is completed, the drive motor 41 is started, driving the connecting shaft 42 to rotate synchronously, thereby driving the grinding disc 43 to rotate. At the same time, the horizontal module 10 is started, so that the movable end of the horizontal module 10 drives the mounting box 11 to slide toward the grinding table 2, thereby driving the grinding disc 43 to move above the car sign; the lifting cylinder 8 is started, and the piston rod of the lifting cylinder 8 contracts, driving the mounting plate 9 and the mounting box 11 to move downward, thereby driving the grinding disc 43 to move downward, so that the rotating grinding disc 43 is close to the surface of the car sign and grinds the surface of the car sign.

[0047] Reference Figure 2 and Figure 5When one side of the car sign is polished, the vacuum pump 33 stops running, the lifting cylinder 51 starts, and the piston rod of the lifting cylinder 51 extends upward, driving the grid plate 52 and the multiple lifting rods 53 to move upward. The multiple lifting rods 53 below the clamping groove 321 will lift the car sign placed in the clamping groove 321 after passing through the adsorption holes 311. The multiple lifting rods 53 not below the clamping groove 321 will abut against the positioning plate 32 after passing through the adsorption holes 311, so that under the action of the plug-in portion 532 and the elastic member 534, the lifting rods 53 gradually contract, which helps to ensure the lifting effect of the multiple lifting rods 53 below the clamping groove 321 on the car sign.

[0048] Reference Figure 1 and Figure 6 The flipping mechanism further includes a moving assembly 6 and a flipping assembly 7. The moving assembly 6 includes a linear module 61, a connecting frame 62, an electric push rod 63, and a mounting frame 64. The linear module 61 is vertically fixedly mounted on the polishing table 2. The connecting frame 62 is fixedly connected to the movable end of the linear module 61. The electric push rod 63 is fixedly mounted in the connecting frame 62. The mounting frame 64 is movably placed in the connecting frame 62 and is fixedly connected to the output end of the electric push rod 63. The flipping assembly 7 includes a rotary motor 71 and a pneumatic clamp 72. The rotary motor 71 is fixedly placed in the mounting frame 64. The output end of the rotary motor 71 passes through the side walls of the mounting frame 64 and the connecting frame 62. The pneumatic clamp 72 is fixedly mounted at the output end of the rotary motor 71 and is located outside the connecting frame 62.

[0049] Reference Figure 1 and Figure 6 During the lifting process of the car sign, the linear module 61 is activated, driving the connecting frame 62 and the mounting frame 64 to move vertically, thereby facilitating the vertical adjustment of the pneumatic clamp 72. When the pneumatic clamp 72 reaches the same height as the lifted car sign, the electric push rod 63 is activated, driving the mounting frame 64 toward the lifted car sign, thereby driving the pneumatic clamp 72 to a clamping position for the car sign. Once the pneumatic clamp 72 reaches the clamping position, it is activated to clamp the car sign. The rotary motor 71 is then activated, driving the pneumatic clamp 72 and the car sign to rotate, thereby flipping the car sign.

[0050] Reference Figure 2 and Figure 6After the car sign is flipped over, the flipped car sign is placed on multiple lifting rods 53 through the cooperation of the linear module 61 and the electric push rod 63, and then the lifting rods 53 and the car sign are driven downward by the lifting cylinder 51, so that the flipped car sign is snapped into the snap-on groove 321, which helps to polish the flipped car sign. Compared with manually flipping the car sign, it helps to improve the convenience of the operating steps when polishing the car sign, thereby helping to improve the polishing efficiency of the car sign.

[0051] The implementation principle of the embodiment of the present application is as follows: before polishing the car sign, the operator clamps the car sign and places it in the clamping groove 321, starts the vacuum pump 33, and the vacuum pump 33 vacuums the interior of the positioning box 31 through the connecting pipe 34, thereby generating a negative pressure inside the positioning box 31, and then generating suction in the multiple adsorption holes 311, which adsorbs and positions the car sign, helps to fix the position of the car sign, thereby helping to improve the stability of the car sign during the subsequent polishing process, and thus helps to improve the polishing effect of the polishing device on the car sign.

[0052] After the car sign is positioned, the drive motor 41 is started, driving the connecting shaft 42 to rotate synchronously, thereby driving the grinding disc 43 to rotate. At the same time, the horizontal module 10 is started, so that the movable end of the horizontal module 10 drives the mounting box 11 to slide toward the grinding table 2, thereby driving the grinding disc 43 to move above the car sign. The lifting cylinder 8 is started, and the piston rod of the lifting cylinder 8 contracts, driving the mounting plate 9 and the mounting box 11 to move downward, thereby driving the grinding disc 43 to move downward, so that the rotating grinding disc 43 is close to the surface of the car sign and grinds the surface of the car sign. The motor 121 is operated, driving the screw 122 to rotate. Under the combined action of the screw and guide rod 123, the connecting seat 124 slides within the mounting box 11, thereby helping to drive the grinding disc 43 to slide in the horizontal direction, thereby helping to enable the grinding disc 43 to grind different positions on the surface of the car sign.

[0053] When one side of the car sign is polished, the vacuum pump 33 stops running, the lifting cylinder 51 starts, and the piston rod of the lifting cylinder 51 extends upward, driving the grid plate 52 and the multiple lifting rods 53 to move upward. The multiple lifting rods 53 below the clamping groove 321 will lift the car sign placed in the clamping groove 321 after passing through the adsorption holes 311. The multiple lifting rods 53 not below the clamping groove 321 will abut against the positioning plate 32 after passing through the adsorption holes 311, so that under the action of the plug-in part 532 and the elastic member 534, the lifting rods 53 gradually shrink, which helps to ensure the lifting effect of the multiple lifting rods 53 below the clamping groove 321 on the car sign.

[0054] During the lifting process of the vehicle sign, the linear module 61 is activated, driving the connecting frame 62 and the mounting frame 64 to move vertically, thereby facilitating the vertical adjustment of the pneumatic clamp 72. When the pneumatic clamp 72 reaches the same height as the lifted vehicle sign, the electric push rod 63 is activated, driving the mounting frame 64 toward the lifted vehicle sign, thereby driving the pneumatic clamp 72 to a position to grip the vehicle sign. Once the pneumatic clamp 72 reaches the gripping position, it is activated to grip the vehicle sign. The rotary motor 71 is then activated, driving the pneumatic clamp 72 and the vehicle sign to rotate, thereby flipping the vehicle sign.

[0055] After the car sign is flipped over, the flipped car sign is placed on multiple lifting rods 53 through the cooperation of the linear module 61 and the electric push rod 63, and then the lifting rods 53 and the car sign are driven downward by the lifting cylinder 51, so that the flipped car sign is snapped into the snap-in groove 321, which helps to polish the flipped car sign. Compared with manually flipping the car sign, it helps to improve the convenience of the operating steps when polishing the car sign, thereby helping to improve the polishing efficiency of the car sign.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
