[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] Example 1:

[0024] A tin anti-scratch spraying device for copper plate surface includes a support frame 1, a fixing frame 2, a spraying assembly 3, a spray gun 4, and a rotating assembly 5. A conveyor belt 6 is installed inside the support frame 1. Two contact belts 7 are symmetrically arranged on the outer circumference of the conveyor belt 6. A groove 8 is formed at the top of each contact belt 7, and an air bladder 9 is installed within the groove 8. An air inlet pipe 10 is connected to one side of each air bladder 9, and one end of the air inlet pipe 10 extends through the contact belt 7. The fixing frame 2 is located at the top of the support frame 1, and the spraying assembly 3 is located inside the fixing frame 2. Spray guns 4 are connected to both sides of the coating component 3. The rotating component 5 is located outside the coating component 3 and is used to rotate the spray guns 4. Air pumps 12 and electric push rods 15 are provided on both sides of the fixed frame 2. The output end of the air pump 12 passes through the fixed frame 2 and is connected to the air supply hose 13 and the air supply connector 14 in sequence. The output shaft of the electric push rod 15 passes through the fixed frame 2 and is connected to the push rod 16 and the push plate 17 in sequence. The push plate 17 is fixedly sleeved on the outside of the air supply connector 14. The air supply connector 14 is adapted to the air inlet pipe 10.

[0025] In this embodiment, the bottom of the airbag 9 is bonded to the inner wall of the groove 8 to prevent the airbag 9 from detaching from the groove 8 when the area of ​​the groove 8 on the contact belt 7 moves to the bend of the conveyor belt 6 or below it. When it is not necessary to spray the side of the copper plate, the spray gun 4 can be rotated upward by the rotating component 5 to avoid the copper plate being too wide and occupying the internal space of the fixed frame 2. The inner surface of the air supply connector 14 can be tightly fitted and slid against the outer surface of the air inlet pipe 10. The air pump 12 is started to supply air into the air inlet pipe 10 through the air supply hose 13 and the air supply connector 14 so that all the gas output by the air pump 12 can flow into the air inlet pipe 10.

[0026] The spraying assembly 3 includes a feed pump 31, a storage tank 32, an output pipe 33, a spraying main pipe 34, and a nozzle 35. The input end of the feed pump 31 is connected to the storage tank 32, and the output end of the feed pump 31 is connected to the output pipe 33. The output pipe 33 passes through the fixed frame 2 and is connected to the spraying main pipe 34 and the nozzle 35 in sequence. There are three nozzles 35 evenly distributed at the bottom of the spraying main pipe 34.

[0027] In this embodiment, the paint is added into the storage tank 32, the feed pump 31 is started, the paint in the storage tank 32 is extracted, and then passes through the output pipe 33 and the spraying main pipe 34 in sequence, and finally sprays the paint downward through the nozzle 35, thereby spraying the upper surface of the copper plate.

[0028] Connecting rods 19 are provided on both sides of the top of the spraying main pipe 34, and the top of the connecting rods 19 are connected to the fixed frame 2.

[0029] In this embodiment, the connecting rods 19 on both sides are used to ensure the stability of the spraying main pipe 34.

[0030] A material supply hose 18 is connected between the spray gun 4 and the spraying main pipe 34.

[0031] The rotating assembly 5 includes a hinge base 51, a rotating rod 52, a motor 53, and a connecting arm 54. The rotating rod 52 is rotatably mounted inside the hinge base 51. The motor 53 is located outside the hinge base 51, and the output shaft of the motor 53 is connected to the rotating rod 52. One end of the connecting arm 54 is fixedly sleeved on the outside of the rotating rod 52, and the other end of the connecting arm 54 is connected to the spray gun 4.

[0032] In this embodiment, the starter motor 53 drives the rotating rod 52 to rotate, which in turn drives the spray gun 4 to flip through the connecting arm 54.

[0033] The top of the airbag 9 has several evenly distributed rubber protrusions 11.

[0034] In this embodiment, a number of evenly distributed rubber protrusions 11 are used to ensure the stability of the copper plate when it is placed horizontally above the airbag 9. The rubber protrusions 11 can also increase the distance the copper plate moves upward to a certain extent when the airbag 9 is inflated.

[0035] The top surface of the rubber protrusion 11 and the top surface of the contact strip 7 are on the same horizontal plane.

[0036] Working principle:

[0037] When it is necessary to spray the upper surface of the copper plate, the copper plate is placed on the two contact belts 7 on both sides, so that the copper plate is above the airbag 9. The conveyor belt 6 is started for transportation, which drives the contact belt 7 on the outer ring of the conveyor belt 6 to move accordingly. When the copper plate at the top of the contact belt 7 moves into the fixed frame 2, the upper surface of the copper plate is sprayed by the spraying assembly 3. Specifically, the paint is added into the storage tank 32, the feed pump 31 is started to extract the paint in the storage tank 32, and then passes through the output pipe 33 and the spraying main pipe 34 in sequence, and finally sprays the paint downward through the nozzle 35, thereby spraying the upper surface of the copper plate. There are three nozzles 35 evenly distributed at the bottom of the spraying main pipe 34 to ensure the uniformity of the spraying on the upper surface of the copper plate.

[0038] When it is necessary to spray the side surface of the copper plate, the contact belt 7 continues to move via the conveyor belt 6. When the airbag 9 is transported into the fixed frame 2, aligning the air inlet pipe 10 with the air delivery connector 14, the electric push rod 15 is activated to extend its output shaft. This, through the push rod 16 and push plate 17, moves the air delivery connector 14 toward the air inlet pipe 10 until the air delivery connector 14 is completely fitted onto the outside of the air inlet pipe 10, establishing a connection between the air delivery connector 14 and the air inlet pipe 10. The air pump 12 is then activated to deliver air into the air inlet pipe 10 through the air delivery hose 13 and the air delivery connector 14. This causes the airbags 9 in the groove 8 to expand, and the airbags 9 on both sides expand upward, thus lifting the copper plate above the airbags 9 to a certain height so that the subsequent spray gun 4 can spray the side of the copper plate as much as possible. The rotating component 5 drives the spray gun 4 to rotate, so that the spray gun 4 flips downward so that it faces the side of the lifted copper plate. The feed pump 31 is started to extract the paint in the storage tank 32 and output the paint to the feed hoses 18 on both sides through the output pipe 33 and the spraying main pipe 34 in sequence. The paint is then sprayed onto the side of the copper plate through the spray guns 4 on both sides, thus completing the spraying work on the side surface of the copper plate.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
