Description

Technical Field

[0001] The invention relates to the technical field of metal processing spraying, and more specifically to an automatic spraying equipment for metal processing. Background Art

[0002] Metal spraying is a material protection technology that uses a high-speed particle flow of molten metal to spray onto the surface of a substrate to produce a coating. The most commonly used metal materials are zinc, aluminum and aluminum-zinc alloys, which are mainly used to protect large steel structures. The characteristics of metal processing spraying are: there is no upper limit on the size of the workpiece, the substrate is generally heated no more than 200°C, the adhesion between the coating and the substrate can be as high as 7 MPa, and the surface roughness after spraying can be reduced to Ra1.25 microns, and after processing it can be reduced to Ra0.16~0.04 microns.

[0003] Metal spraying can be used for mechanical repair, such as arc spraying of medium carbon steel wire or spring steel wire to repair worn crankshafts and transmission shafts of machine tools, and to improve the wear resistance of mechanical parts. Plasma spray welding of high chromium cast iron on ordinary steel plates can extend its service life. It can also be used for mechanical parts resistant to strong chemical media, such as arc or plasma spraying of titanium or titanium-tantalum layers in a protective atmosphere to prevent the inner surface of the pump housing and the agitator from being corroded by oxidizing acids containing chloride ions. When metal is sprayed, such as when a metal plate needs to be sprayed, after one side is sprayed, the sprayed part needs to be taken out, turned over, and then sprayed on the other side. Therefore, when spraying a traditional metal plate, two processes are required, so the spraying process takes a long time and the processing efficiency is low; During the spraying process, since both sides of the plate need to be sprayed, after turning over, if the first side after spraying is not in a dry state, after turning over, the sprayed side will contact with its clamping device, which will cause damage to the sprayed surface, thereby making the quality of the metal after spraying poor and affecting its performance.

[0013] Technical effects and advantages of the present invention: 1.

The present invention can rotate the rotating drum by rotating the anti-skid ribs on the rotating drum. When the rotating drum rotates, the threaded rod inside it moves in the rotating drum. When the threaded rod moves, the second limit block is driven to move through the fixed block, and the distance between the first limit block and the second limit block is adjusted to adapt to different metals to be sprayed. The circular electromagnet in the connecting component can be reversely energized.

When the servo motor drives the conveyor belt through the output shaft to run, the output shaft synchronously drives the synchronous belt to rotate, thereby causing the rotating blade to rotate.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The automatic spraying equipment for metal processing involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0026] Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 8The present invention provides an automated spraying device for metal processing, comprising a conveyor belt 1, a collecting pool 12 is fixedly connected to the bottom end of the conveyor belt 1, a shielding shell 2 is fixedly connected to the top of the collecting pool 12, the conveyor belt 1 is located inside the shielding shell 2, both sides of the conveyor belt 1 are fixedly connected to a turning mechanism 7, the side of the turning mechanism 7 is fixedly connected to an adjusting mechanism 8, the inside of the turning mechanism 7 is movably connected to a metal 10 to be sprayed, a second placement plate 13 is provided on the side of the turning mechanism 7 away from the adjusting mechanism 8, a rack mechanism 11 is fixedly connected to the top of the collecting pool 12, the rack mechanism 11 is located on the movement track of the turning mechanism 7, a drying mechanism 9 is fixedly connected to the side of the shielding shell 2 away from the conveyor belt 1, and the top of the shielding shell 2 is away from the drying mechanism A first spray head 3 is fixedly connected to one side of 9, a second spray head 4 is fixedly connected to the middle of the top inside the shielding shell 2, a first intelligent camera 5 is provided on the side of the first spray head 3 close to the second spray head 4, a second intelligent camera 6 is provided on the side of the second spray head 4 close to the first spray head 3, the tops of the first intelligent camera 5 and the second intelligent camera 6 are fixedly connected to the top inside the shielding shell 2, an output shaft 102 is fixedly connected to the side of the conveyor belt 1 away from the metal 10 to be sprayed, a servo motor 101 is fixedly connected to the side of the output shaft 102, the side of the servo motor 101 close to the output shaft 102 is fixedly connected to the outside of the shielding shell 2, and the side of the output shaft 102 away from the servo motor 101 is fixedly connected to the side of the drying mechanism 9.

[0027] In the embodiment of the present application, when the metal 10 to be sprayed is being sprayed, when the metal 10 to be sprayed is sent to the inside of the shielding shell 2, it will first be sprayed under the first spray head 3, and after spraying, it will be detected by the first intelligent camera 5. When the first intelligent camera 5 detects that its sprayed surface is qualified, the first intelligent camera 5 controls the second spray head 4 not to start, and when the first intelligent camera 5 detects that the surface of the metal 10 to be sprayed is unqualified, the first intelligent camera 5 controls the second spray head 4 to start, and after the metal 10 to be sprayed is turned over, when spraying, the metal 10 to be sprayed moves from the inside of the shielding shell 2 to the outside, so the metal 10 to be sprayed is first sprayed under the second spray head 4, and at this time it is detected by the second intelligent camera 6. Therefore, when the spraying is qualified, the first spray head 3 is not started. Therefore, the present application can be carried out according to the actual spraying situation. Choosing to perform one spraying or two sprayings can save spraying raw materials. In addition, it should be noted that the first smart camera 5 and the second smart camera 6 can detect the spraying surface, which is a conventional technical means in this field. This application does not limit it in detail. When the metal 10 to be sprayed is flipped, it is in the process of sending the metal 10 to be sprayed to the inside of the conveyor belt 1. At this time, the output shaft 102 rotates forward, and the drying mechanism 9 blows air outward. The flipping process is located on the side of the drying mechanism 9. After flipping, the metal 10 to be sprayed moves outward, and the drying mechanism 9 will inhale air. However, the spraying position of the metal 10 to be sprayed is far away from the drying mechanism 9, so it will not affect the drying mechanism 9, and there is enough distance between the drying mechanism 9 and the second spray head 4 to prevent the drying mechanism 9 from being affected by the paint molecules sprayed from the second spray head 4.

[0028] Reference Figure 4 , Figure 4 , Figure 6 as well as Figure 7The flip mechanism 7 includes a rotating gear 701 that can provide power, a rotating shaft 702 is fixedly connected to the inner side of the rotating gear 701, and first limit blocks 703 are fixedly connected to both ends of the rotating shaft 702. The two first limit blocks 703 are fixedly connected to the second limit blocks 704 through the adjustment mechanism 8. The bottom end of the first limit block 703 is movably connected to a connecting plate 705, and the bottom end of the second limit block 704 is movably connected to a first placement plate 708. The sides of the connecting plate 705 and the first placement plate 708 are fixedly connected to the sides of the conveyor belt 1. The side of the connecting plate 705 on one side away from the conveyor belt 1 is fixedly connected to a fixed plate 706, and the side of the connecting plate 705 on the other side away from the conveyor belt 1 is connected to the connecting component through the fixed plate 706. 707 is fixedly connected. After the second limit block 704 rotates around the rotating shaft 702, the second limit block 704 is located at the top of the second placement plate 13, and the bottom end of the root circle of the rotating gear 701 is located below the bottom end of the fixed plate 706. The connecting component 707 includes a connecting cylinder 7071 fixedly connected to the fixed plate 706. A circular electromagnet 7072 is fixedly connected to the side of the connecting cylinder 7071 away from the rotating shaft 702. A magnetic rod 7073 is movably connected to the side of the circular electromagnet 7072 close to the rotating shaft 702. A support spring 7074 is movably connected to the side of the magnetic rod 7073 away from the circular electromagnet 7072. A avoidance hole adapted to the support spring 7074 is provided inside the circular electromagnet 7072.

[0029] In the embodiment of the present application, when the rotating gear 701 is moving, it will contact the rack mechanism 11. After contacting the rack mechanism 11, the rotating gear 701 will rotate. When the rotating gear 701 rotates, it will drive the rotating shaft 702, the first limit block 703 and the second limit block 704 to rotate, so that the metal 10 to be sprayed is turned over, and the second limit block 704 will fall on the second placement plate 13 after turning over, so that it will also be supported after turning over to ensure its stability, and connecting components 707 are provided on both sides of the rotating shaft 702, and the circular inner part of the connecting component 707 is provided. When the circular electromagnet 7072 is energized in the forward direction, the magnetic repulsion between the circular electromagnet 7072 and the magnetic rod 7073 is converted into magnetic attraction. At this time, the magnetic rod 7073 is moved away from the two ends of the rotating shaft 702. At this time, the rotating shaft 702 is separated from the connecting plate 705. At this time, the rotating shaft 702 is moved away, and the first limit block 703 and the second limit block 704 are both removed and can be cleaned. Therefore, the present application can freely choose whether to fix the rotating shaft 702. When the rotating shaft 702 is fixed, its flipping stability is guaranteed. When the rotating shaft 702 is loosened, it can be removed for cleaning.

[0030] Reference Figure 4 as well as Figure 6The adjustment mechanism 8 includes a connecting block 801 fixedly connected to the first limit block 703, a side of the connecting block 801 away from the first limit block 703 is provided with a avoiding groove adapted to the limit rod 802, the side of the limit rod 802 away from the connecting block 801 is fixedly connected with a rotating cylinder 803, the side of the rotating cylinder 803 away from the first limit block 703 is provided with a threaded hole adapted to the threaded rod 804, the side of the threaded rod 804 away from the rotating cylinder 803 is fixedly connected with a fixing block 805, the side of the fixing block 805 away from the threaded rod 804 is fixedly connected to the side of the second limit block 704, and the fixing block 805 is fixedly connected with a shielding plate 806 near the top of the threaded rod 804.

[0031] In the embodiment of the present application, when the rotating cylinder 803 rotates, the threaded rod 804 moves inside the rotating cylinder 803. When the threaded rod 804 moves, the second limit block 704 is driven to move through the fixed block 805, thereby adjusting the distance between the first limit block 703 and the second limit block 704 to make it adapt to the metal 10 to be sprayed. Therefore, the present application can be adjusted according to the size of the metal 10 to be sprayed to meet the processing requirements of different metals 10 to be sprayed.

[0032] Reference Figure 2 and Fig.10 The rack mechanism 11 includes a connecting rack 1103 that can cooperate with the rotating gear 701, the bottom end of the connecting rack 1103 is fixedly connected to a square magnetic plate 1102, the side of the square magnetic plate 1102 is movably connected to a fixed box 1101, the bottom end of the fixed box 1101 is fixedly connected to the top of the collecting pool 12, the bottom end of the inside of the fixed box 1101 is fixedly connected to an electromagnet 1104, and the connecting rack 1103 can allow the rotating gear 701 to rotate one hundred and eighty degrees.

[0033] In the embodiment of the present application, when the metal 10 to be sprayed is flipped, there is a magnetic repulsion force between the square magnetic plate 1102 and the electromagnet 1104, so the connecting rack 1103 cooperates with the rotating gear 701 to rotate the rotating gear 701. After flipping, the magnetic repulsion force between the electromagnet 1104 and the square magnetic plate 1102 changes to a magnetic attraction force, and the connecting rack 1103 will move downward. Therefore, when the servo motor 101 controls the conveyor belt 1 to move in the opposite direction, the rotating gear 701 will not contact the connecting rack 1103, thereby ensuring the overall smooth operation.

[0034] Reference Figure 2 , Figure 8 and Fig. 9The drying mechanism 9 includes a synchronous belt 901 that rotates synchronously with the output shaft 102, a connecting shaft 902 is fixedly connected to the side of the synchronous belt 901, a first bevel gear 903 is fixedly connected to the side of the connecting shaft 902 away from the synchronous belt 901, the bottom end of the first bevel gear 903 is meshed with a second bevel gear 904, the bottom end of the second bevel gear 904 is fixedly connected to a fan shaft 905, the bottom end of the fan shaft 905 is fixedly connected to a rotating blade 906, the rotating blade 906 is located in a gas box 907, the top of the gas box 907 is fixedly connected to the top of the inside of the conveyor belt 1, the inside of the gas box 907 is fixedly connected to a heating plate 908, and the side and bottom of the gas box 907 are provided with exhaust holes.

[0035] In the embodiment of the present application, the rotating blades 906 blow air outward when rotating, and the heating plate 908 makes the gas box 907 filled with hot air. Therefore, the gas blown out by the rotating blades 906 is dry and has a high temperature. When it is blown onto the flipped metal 10 to be sprayed, the sprayed surface is dried to avoid damage to the sprayed coating when it is flipped. Exhaust holes are provided on the side and bottom of the gas box 907. When the metal 10 to be sprayed is flipped ninety degrees, the sprayed surface is located on the side of the gas box 907. Therefore, exhaust holes are provided on the side and bottom, rather than only on the bottom, to improve the drying effect.

[0036] The working principle of the present invention is as follows: during spraying, the rotating cylinder 803 is rotated according to the size of the metal 10 to be sprayed, and when the rotating cylinder 803 rotates, the threaded rod 804 moves in the rotating cylinder 803, and when the threaded rod 804 moves, the second limit block 704 is driven to move through the fixed block 805, thereby adjusting the distance between the first limit block 703 and the second limit block 704 to make it adapt to the metal 10 to be sprayed; The metal 10 to be sprayed is placed between the first limit block 703 and the second limit block 704, the servo motor 101 is started and drives the conveyor belt 1 to run through the output shaft 102, and the metal 10 to be sprayed is sent to the bottom of the first spray head 3 for spraying. After spraying, it is detected by the first intelligent camera 5. When the first intelligent camera 5 detects that the sprayed surface is qualified, the first intelligent camera 5 controls the second spray head 4 not to start. When the first intelligent camera 5 detects that the surface of the metal 10 to be sprayed is unqualified, the first intelligent camera 5 controls the second spray head 4 to start, and the upper surface of the metal 10 to be sprayed is sprayed twice to ensure its spraying quality; After the upper surface of the metal 10 to be sprayed is sprayed, the flipping mechanism 7 moves synchronously with the conveyor belt 1, and the rotating gear 701 in the flipping mechanism 7 contacts the connecting rack 1103 in the rack mechanism 11. At this time, the rotating gear 701 rotates around the rotating shaft 702. When the rotating gear 701 rotates, it drives the first limit block 703 to rotate. The first limit block 703 drives the second limit block 704 to rotate through the adjustment mechanism 8. At this time, the metal 10 to be sprayed between the first limit block 703 and the second limit block 704 rotates synchronously, so the metal 10 to be sprayed will be flipped, and the original upper surface of the metal 10 to be sprayed will turn to the bottom. After the metal 10 to be sprayed is flipped, the second limit block 704 falls from the top of the first placement plate 708 to the top of the second placement plate 13; When the metal 10 to be sprayed is flipped, the electromagnet 1104 changes from being energized in the forward direction to being energized in the reverse direction, so the magnetic repulsion between the electromagnet 1104 and the square magnetic plate 1102 changes to being energized in the magnetic attraction direction, and the connecting rack 1103 moves downward. Therefore, when the servo motor 101 controls the conveyor belt 1 to move in the reverse direction, the rotating gear 701 does not contact the connecting rack 1103, and the metal 10 to be sprayed moves outward at this time. When moving outward, the metal 10 to be sprayed turns to the upper surface and is first located below the second spray head 4 for spraying. When the second intelligent camera 6 detects that the second spray head 4 has sprayed correctly, the second intelligent camera 6 controls the first spray head 3 not to start, and directly transports the metal 10 to be sprayed out. When the second intelligent camera 6 detects that there is a problem with the second spray head 4, the second intelligent camera 6 controls the first spray head 3 to start, and the metal 10 to be sprayed is sent out after spraying again to ensure the spraying effect on both sides. After sending it out, the metal 10 to be sprayed can be removed, and the rotating shaft 702 is reset; When the metal 10 to be sprayed is turned over, the output shaft 102 is in a rotating state. When the output shaft 102 rotates, the connecting shaft 902 is driven to rotate through the synchronous belt 901. When the connecting shaft 902 rotates, the fan shaft 905 is driven to rotate through the first bevel gear 903 and the second bevel gear 904, thereby rotating the rotating blade 906. When the rotating blade 906 rotates, it blows air outward. The heating plate 908 makes the gas box 907 filled with hot air. Therefore, the gas blown out by the rotating blade 906 is dry and has a high temperature. When it blows onto the turned metal 10 to be sprayed, it will dry the sprayed surface to avoid damage to the sprayed coating when it is turned over. After a certain period of spraying, the circular electromagnet 7072 in the connecting component 707 changes from being energized in the forward direction to being energized in the reverse direction. At this time, the magnetic repulsion between the circular electromagnet 7072 and the magnetic rod 7073 is converted into a magnetic attraction. At this time, the magnetic rod 7073 is removed from both ends of the rotating shaft 702. The rotating shaft 702, the first limit block 703 and the second limit block 704 can be removed and cleaned, and a new rotating shaft 702 can be replaced. At this time, the rotating shaft 702 is aligned with the magnetic rod 7073, and the circular electromagnet 7072 becomes energized in the forward direction, so that the magnetic rod 7073 can be pushed into the rotating shaft 702 to fix the rotating shaft 702.

[0037] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
