Description

Technical Field

[0001] The invention relates to the field of metal coating, in particular to a coating device for lightweight metal plates. Background Art

[0002] Lightweight metal plates include zinc plates and other materials. Lightweight metal plate coating refers to a surface treatment process in which a thin film is coated on the metal surface. A protective film can be formed on the metal surface to isolate the metal from external corrosive media such as oxygen, moisture, acid and alkali solutions, thereby preventing metal corrosion and extending service life. It is widely used in various industrial fields.

[0003] The metal plate is coated by evaporation. The metal plate needs to be placed in a vacuum chamber, and the coating material is evaporated by heating, and then condensed into a film on the surface of the substrate. The existing Chinese public patent document: CN217378010U discloses a vacuum coating device with uniform coating. Steam boxes are respectively arranged on both sides of the coating bin. The coating steam in the steam box will enter the two sides of the coating bin respectively through two connecting pipes. Since the metal plate is placed vertically, both sides of the metal plate will be completely wrapped by the coating steam to ensure the yield of the coated product. Although the side of the metal plate can be uniformly coated, the surface of the metal plate needs to be fixed by multiple clamping plates. The clamping plates will block the surface of the metal plate, so that after the metal plate is coated, the contact surface between the clamping plate and the metal plate cannot be coated, and it is difficult to achieve a uniform coating effect.

The mounting plate 3 is fixedly installed on the outer side of the mounting block 12. The mounting block 12 can drive the two mounting plates 3 to replace their positions by driving the motor 11. A mounting column 13 is provided on the side of the U-shaped clamp 8 close to the metal plate body 4. A ball 14 that contacts the outer side of the metal plate body 4 is rotatably installed on the outer side of the mounting column 13. The metal plate body 4 is supported by the ball 14. A fixing cylinder 15 is slidably installed on the outer side of the mounting column 13. The fixing cylinder 15 is fixedly installed on the inner side of the U-shaped clamp 8. A spring 2 16 is fixedly installed between the inner side of the fixing cylinder 15 and the end of the mounting column 13 away from the ball 14. The elasticity of the spring 2 16 is used to clamp the ball 14 on the mounting column 13 to position the metal plate body 4.

[0032] The staff can insert the two metal plate bodies 4 into the four U-shaped clips 8 corresponding to the outer sides of the two mounting plates 3 respectively, and use the elasticity of the spring 2 16 to make the ball 14 on the mounting column 13 press against the top and bottom of the metal plate body 4 to achieve the clamping and positioning of the metal plate body 4, and the contact area between the ball 14 and the metal plate body 4 is small, so that the plating material in the crucible 2 evaporates and coats the bottom of the metal plate body 4, and after the bottom of the metal plate body 4 is coated, the driving motor 11 can drive the mounting plate 3 to rotate through the mounting block 12, so that the positions of the two mounting plates 3 are replaced, and during the rotation of the mounting plate 3, the metal plate body 4 can be turned over, and the other side of the metal plate body 4 can be coated, thereby achieving a uniform coating effect.

[0033] The fixed plate mechanism includes a support rod 17 fixedly mounted on the inner wall of the top of the device housing 1, a support tube 18 is fixedly mounted on the outer side of the support rod 17, the support tube 18 is located between the two mounting frames 6, the output end of the drive motor 11 is rotatably mounted on the inner side of the support tube 18, so as to improve the stability of the rotation of the output end of the drive motor 11, a slide column 19 is fixedly mounted on the outer side of the U-shaped clamp 8, a long groove is provided on the outer side of the mounting frame 6 for the slide column 19 to limit the sliding, a push column 20 is fixedly mounted on the end of the slide column 19 away from the U-shaped clamp 8, a stop plate 21 is fixedly mounted on the right side inside the device housing 1, a stop plate 22 is fixedly mounted on the side of the support tube 18 close to the stop plate 21, and the widths of the stop plates 21 and 22 are both The distance between the two adjacent sliding columns 19 is greater than that between the two adjacent sliding columns 19, so that the sliding column 19 can push the sliding column 19 to move when it contacts the abutment plate 1 21 or the abutment plate 22. The abutment plate 1 21, the abutment plate 22 and the outer side of the sliding column 19 are all corresponding arc-shaped structures, which facilitates the abutment plate 1 21 and the abutment plate 22 to push the sliding column 19 to move. The inner side of the U-shaped clip 8 is fixedly installed with a sleeve 23 located between the two mounting columns 13, and the inner side of the sleeve 23 is slidably installed with a prismatic rod 24. A spring 3 25 is fixedly installed between the prismatic rod 24 and the inner side of the sleeve 23. The end of the prismatic rod 24 away from the spring 3 25 is fixedly installed with a clamping column 26 in contact with the outer side of the metal plate body 4, providing positioning for the side of the metal plate body 4.

[0034] When the mounting block 12 drives the mounting plate 3 to rotate and move, the mounting plate 3 drives the mounting frame 6 to move synchronously, so that the two mounting frames 6 drive the corresponding push columns 20 to contact the abutment plate 1 21 and the abutment plate 2 22 respectively, and the push columns 20 drive the sliding column 19 to move along the long groove on the mounting frame 6, and the sliding column 19 drives the U-shaped clamp 8 to move synchronously, so that the U-shaped clamp 8 drives the sleeve seat 9 to move along the outer side of the slide rod 7, and the U-shaped clamp 8 can respectively drive the ball 14 on the mounting column 13 and the clamping column 26 on the prismatic rod 24 to move along the surface of the metal plate body 4 through the fixed tube 15 and the sleeve 23, so as to adjust the position of the clamping point of the metal plate body 4, so as to facilitate the plating material to coat the previous clamping point, thereby achieving the effect of comprehensive coating.

[0035] Working principle: First, the staff opens the device housing 1, and inserts the two metal plate bodies 4 into the four U-shaped clips 8 corresponding to the outer sides of the two mounting plates 3. The outer sides of the metal plate bodies 4 contact the outer sides of the ball bearings 14, so that the ball bearings 14 push the mounting posts 13 to move along the inner side of the fixing tube 15. The ball bearings 14 are pressed against the top and bottom of the metal plate bodies 4 by the elasticity of the springs 16. The four ball bearings 14 can clamp and position the top and bottom of the metal plate bodies 4. In addition, the outer sides of the clamping posts 26 contact the sides of the metal plate bodies 4. The springs 16 are used to push the mounting posts 13 along the inner side of the fixing tube 15. The elasticity of the spring 16 enables the clamping column 26 to provide clamping and positioning for the side of the metal plate body 4. Subsequently, the staff puts the plating material into the crucible 2, closes the device housing 1, and extracts the air in the device housing 1 through the exhaust valve 5. The plating material in the crucible 2 evaporates and coats the bottom of the metal plate body 4. When the bottom coating of the metal plate body 4 is completed, the staff starts the driving motor 11. The driving motor 11 drives the two mounting plates 3 to rotate and move through the mounting block 12, so that the positions of the two mounting plates 3 are replaced. At the same time, the mounting plate 3 drives the push column 20 and the mounting frame 6 to rotate. The metal plate body 4 moves synchronously, and the mounting frame 6 drives the push column 20 to contact the abutment plate 1 21 or the abutment plate 22, so that the push column 20 moves along the arc surface on the abutment plate 1 21 or the abutment plate 22 to the side surface on the abutment plate 1 21 or the abutment plate 22. At the same time, the push column 20 drives the slide column 19 to move along the long groove on the mounting frame 6, so that the slide column 19 drives the U-shaped clip 8 to move synchronously, and the U-shaped clip 8 drives the sleeve seat 9 to move along the outer side of the slide rod 7, so that the U-shaped clip 8 drives the fixed cylinder 15 and the sleeve 23 to move synchronously, and the fixed cylinder 15 and the sleeve 23 respectively drive the rollers on the mounting column 13 The bead 14 and the clamping column 26 on the prismatic rod 24 move along the surface of the metal plate body 4 to adjust the position of the clamping point of the metal plate body 4, which is convenient for the plating material to be plated on the previous clamping point, and during the rotation of the mounting plate 3, the metal plate body 4 can be turned over synchronously to coat the other side of the metal plate body 4. Finally, the driving motor 11 drives the mounting block 12 to rotate repeatedly to complete the comprehensive coating of the metal plate body 4, thereby achieving a comprehensive and uniform coating effect, and two metal plate bodies 4 can be plated at the same time to improve the coating efficiency.

[0036] Example 2: Please refer to Figure 4-Figure 8, this embodiment further explains the first embodiment. The material blocking mechanism shown in the figure includes two blocks 27, both of which are arranged between the mounting plate 3 and the metal plate body 4. The side of the block 27 close to the metal plate body 4 is an arc-shaped structure. The block 27 contacts the outer side of the metal plate body 4 to provide auxiliary support for the outer side of the metal plate body 4. A movable rod 28 is fixedly installed on the side of the block 27 away from the metal plate body 4. A sliding cavity for limiting the sliding of the movable rod 28 is opened on the outer side of the mounting plate 3. A sliding penetrating The guide rod 29 of the movable rod 28 provides guidance for the movement of the movable rod 28. An arc groove 1 30 for limiting the sliding of the movable rod 28 is provided on the inner side of the device housing 1. An arc groove 2 31 for limiting the sliding of the movable rod 28 is provided on the inner side of the device housing 1. The two ends of the arc groove 1 30 are connected to the two ends of the arc groove 2 31. The center of the arc groove 1 30 is located between the two mounting plates 3. The center of the arc groove 2 31 deviates from the center of the arc groove 1 30, so that the movable rod 28 can move along the sliding cavity on the mounting plate 3 when entering the arc groove 2 31.

[0037] In this embodiment: when the staff installs the metal plate body 4, the metal plate body 4 can contact the two blocks 27 on the mounting plate 3, which is convenient for quickly installing the metal plate body 4. When the driving motor 11 drives the mounting block 12 to rotate, the mounting block 12 drives the movable rod 28 to move synchronously through the mounting plate 3, so that the movable rod 28 moves along the inner side of the arc groove 1 30. When the movable rod 28 moves to the inner side of the arc groove 2 31, as the movable rod 28 moves along the arc groove 2 31, the movable rod 28 moves along the guide rod 29 and the sliding cavity on the mounting plate 3. The movable rod 28 can drive the block 27 to move along the outer side of the metal plate body 4 to prevent the block 27 from blocking the side of the metal plate body 4, so as to facilitate the comprehensive coating of the side of the metal plate body 4, thereby achieving the effect of facilitating the rapid installation of the metal plate body 4 and the side coating.

[0038] Example 3: Please refer to Figure 1-Figure 8The present embodiment further illustrates other embodiments. A guide ring 32 is fixedly installed on the inner side of the device housing 1 in the figure. The outer side of the guide ring 32 contacts with the side of the mounting frame 6 away from the mounting plate 3, thereby improving the stability of the movement of the mounting frame 6. A rack plate 33 is fixedly installed on the outer side of the sliding column 19. A cavity for the rack plate 33 to limit the sliding movement is provided inside the mounting frame 6. The two rack plates 33 are symmetrically distributed in the center. A gear 34 that cooperates with the two rack plates 33 is rotatably installed in the cavity of the mounting frame 6 to ensure that the two sliding columns 19 move synchronously. Two telescopic rods 35 symmetrically distributed on the outer side of the sleeve 23 are fixedly installed between the inner side of the U-shaped clamp 8 and the outer side of the clamp column 26 to ensure that the clamp column 26 is in a vertical state with the metal plate body 4. Two symmetrically distributed ball bearings 36 are rotatably installed on the side of the stopper 27 close to the mounting plate 3. A sliding groove for the ball bearings 36 to limit the sliding movement is provided on the outer side of the mounting plate 3 to improve the smoothness of the movement of the stopper 27.

[0039] In this embodiment: when the mounting frame 6 moves, it can move along the outer side of the guide ring 32 to provide support for the side of the mounting frame 6 away from the mounting plate 3 to prevent the mounting frame 6 from being skewed. When the sliding column 19 moves, it can drive the rack plate 33 to move along the cavity of the mounting frame 6, and drive the other rack plate 33 to move synchronously through the gear 34, so that the two rack plates 33 move synchronously, ensuring that the two sliding columns 19 drive the corresponding U-shaped clamps 8 to move synchronously, thereby improving the synchronization of the position adjustment of the ball 14. The telescopic rod 35 can provide auxiliary support for the clamp column 26 to prevent the clamp column 26 from being skewed when the metal plate body 4 pushes the clamp column 26 to move. When the stop block 27 moves, it can drive the ball 2 36 to move along the slide groove on the mounting plate 3. The ball 2 36 can provide auxiliary support for the stop block 27 and improve the smoothness of the movement of the stop block 27.
