Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical device shell painting device. Background Art

[0002] Medical devices are in direct contact with the human body or the medical environment, and their casings must meet requirements such as biocompatibility, corrosion resistance, and resistance to chemical disinfectants. In addition, the casings of medical devices must strictly comply with hygiene requirements. Spray painting can improve the surface smoothness of the device through special coatings, reduce bacterial growth, and ensure the cleanliness and safety of the device. Spray painting not only helps to improve the appearance, but also provides certain protection functions to resist corrosion, oxidation and physical damage from the external environment, and increase the durability and reliability of the equipment.

[0003] In the prior art, when spraying the shell of a medical device, horizontal reciprocating spraying is often used for the moving shell of the medical device, and flowing water curtains are set on both sides to absorb the paint mist and fine particles generated by the spraying. The movement path of the horizontal reciprocating spraying is fixed. During the reciprocating process, the spraying may be repeated in some areas, while insufficient spraying in other areas may occur, resulting in uneven coating distribution. Especially when spraying the shell of a medical device with a complex shape, some curved or difficult-to-reach places are prone to leaving dead corners for spraying, and multiple back and forth passes are required to cover the entire surface, which can easily lead to a long production cycle and low production efficiency. In addition, it is impossible to effectively help guide the paint mist to the water curtain area for filtration, and the paint mist is easy to diffuse, resulting in poor purification effect. The paint mist is not effectively controlled and recovered, which will cause the uncured paint mist to float in the equipment and re-attach to the surface of the medical device that has been sprayed, resulting in uneven coating, surface defects or pollution.

[0018] The beneficial effects of the present invention are as follows: (1) The present invention adopts an adjustable swing paint spraying mechanism. When the paint spraying motor is running, under the action of the connecting rod, the two first bevel gears are driven to rotate simultaneously, so that the second bevel gear drives the first synchronous belt assembly to transmit, drives the driving rod to rotate, and causes the rotating plate to rotate. Then, the second synchronous belt assembly is driven by controlling and adjusting the operation of the motor, so that the threaded rod is lifted up and down, and the limit plate drives the limit member to move up and down, thereby changing the angular relationship between the driving rod and the rotating plate. When the rotating plate rotates synchronously with the driving rod, the rotating plate continues to rotate. Due to the rotation, the limit frame and the T-frame, the T-frame and the fixed frame simultaneously produce a cyclic reciprocating relative rotation, so that the spraying unit discharges the paint from the nozzle through the hose, and the nozzle follows the T-frame to perform a cyclic swinging motion to spray the medical device shell placed on the moving board. By controlling and changing the position relationship of the driving rod, the rotating plate can rotate at different angles and can be adjusted according to the shape of the medical device shell, so that the spraying can better adapt to shells of different shapes, especially curved, complex, and three-dimensional surfaces, and can avoid the situation of dead angles or uneven spraying of the horizontal reciprocating mechanism under these shapes; (2) The present invention adopts a counter-rotating horizontal airflow mechanism. When the paint spraying motor is running, under the action of the connecting rod, the two first bevel gears are driven to rotate simultaneously, thereby driving the second bevel gear to rotate, so that the two chain assemblies are driven to transmit in different directions. When the chain assembly is transmitting, the support rod moves synchronously with the chain in the chain assembly, so that the slider slides back and forth in the slide groove of the moving part, and the slider moves back and forth on the slide rod to adapt to the chain transmission trajectory in the chain assembly. At the same time, the pulley connected to one end of the support rod slides synchronously in the annular groove, and the fan moves along the arc-shaped blades of the fan while following the movement of the support rod. Under the action of the gear, it rotates, and with the cooperation of the secondary gear and the main gear, the two fans and the connecting plate can rotate around the support rod at the same time, and the two fans rotate in opposite directions, so that the fans on the two chain assemblies follow the chain assembly to make opposite circular movements, which can draw the paint mist and fine particles generated during spraying onto the water curtain plate, and form a strong airflow in the spraying area. This airflow movement can help guide the paint mist and particles generated in the spraying area from the central area to both sides, and can be effectively removed, preventing pollutants from returning to the shell surface or equipment, thereby ensuring the surface quality and precision of the product.

[0025] like Figure 6-Figure 12 As shown, the adjustable swing paint spraying mechanism 3 includes a fixing frame 312 fixedly connected to the housing 14, a driving rod 31 is slidably provided on one side of the fixing frame 312, and a fixed limiting member 35 is provided in the middle of the driving rod 31, a limiting plate 36 is engaged with one side of the limiting member 35, a spraying unit 37 is installed on the bottom surface of the limiting plate 36, and the spraying unit 37 is connected to the nozzle 39 through a hose 38, and a threaded rod 33 threadedly connected to the housing 14 is fixedly connected to the side of the limiting plate 36 away from the spraying unit 37, and a threaded rod 33 threadedly connected to the housing 14 is provided on the through end of the limiting plate 36 The second synchronous belt assembly 32, and the driving rod 31 located at the top of the limiter 35 is limited and slidably penetrated by a bearing 34 installed inside the shell 14, which can be adjusted according to the shape of the medical device shell, so that the spraying can better adapt to shells of different shapes, especially curved, complex, and three-dimensional surfaces, and can avoid dead corners or uneven spraying in these shapes when lateral reciprocating spraying.

By adjusting the swing amplitude, it can ensure that the spraying material is evenly and effectively applied to the surface.

[0027] like Figure 10-Figure 16 As shown, water curtain assemblies 4 are arranged on both sides of the regulating motor 313 to capture paint mist to avoid secondary pollution. The water curtain assembly 4 includes a water tank 41 that is connected to the inside of the housing 14 through slots 18 on both sides of the supporting platform 11. The water tank 41 is located at the bottom of the supporting platform 11 and is connected and fixed thereto. A plurality of fixing rods 43 are fixedly connected to the inner wall of the water tank 41. Two water curtain plates 44 located inside the slots 18 are fixedly arranged between the plurality of fixing rods 43. The water curtain plates 44 can effectively capture the paint mist and fine particles generated during the spraying process by forming a water film. These paint mist and particles may cause pollution to the environment and equipment.

The water pump 42 is fixedly connected to the through end of the water pipe 45.

[0028] The working principle of this embodiment is as follows: one end of the conveying frame 13 of the overall equipment is connected and installed with the dryer, and then the medical device housing together with the placement plate 17 is placed on the conveying frame 13, and the conveying motor 19 drives the conveyor belt assembly 16 to transmit, and then the medical device housing placed on the placement plate 17 is moved to the inside of the housing 14 and the support platform 11 to carry out the painting process.

[0029] When the medical device is being painted, the paint motor 21 is running, and under the action of the connecting rod 24, the two first bevel gears 22 are driven to rotate simultaneously, thereby driving the second bevel gear 23 to rotate, prompting the chain components 27 in the two grooves 26 to transmit in different directions, and when the chain component 27 is transmitting, the support rod 216 moves synchronously with the chain in the chain component 27, so that the slider 211 slides back and forth in the slide groove 210 of the moving part 29, and the slider 211 moves back and forth on the slide rod 28 to adapt to the chain transmission trajectory in the chain component 27, and the support rod 216 follows the chain. When the chain in the chain assembly 27 moves, the pulley 217 connected to one end of the support rod 216 slides synchronously in the annular groove 219, and the fan 215 rotates on its own under the action of its arc-shaped fan blades while following the movement of the support rod 216. With the cooperation of the secondary gear 214 and the main gear 213, the two fans 215 and the connecting plate 218 can rotate on their own and in opposite directions while revolving around the support rod 216, so that the fans 215 on the two chain assemblies 27 follow the chain assembly 27 to make opposite circular motions.

[0030] When the fans 215 on the two chain assemblies 27 follow the chain assemblies 27 to make opposite circular motions, the water pump 42 operates to cause the water pipe 45 to suck the water in the water tank 41 and flow out from the water outlet of the water pipe 45. Under the action of gravity, a circulating water flow is formed on the surface of the water curtain plate 44.

[0031] The second bevel gear 23 drives the first synchronous belt assembly 25 to transmit, drives the driving rod 31 to rotate, causes the limit piece 35 and the rotating plate 310 at the bottom of the driving rod 31 to rotate, and then drives the second synchronous belt assembly 32 to transmit by controlling the operation of the regulating motor 313, so that the threaded rod 33 moves up and down, so that the limit plate 36 drives the limit piece 35 to move up and down, and then the driving rod 31 moves synchronously, thereby changing the angular relationship between the driving rod 31 and the rotating plate 310. When the driving rod 31 rotates, the rotating plate 310 When the follower driving rod 31 rotates synchronously, the limit frame 311 and the T-frame 314 and the T-frame 314 and the fixed frame 312 simultaneously produce relative rotation, and because the rotating plate 310 continues to rotate, the limit frame 311 and the T-frame 314 and the T-frame 314 and the fixed frame 312 simultaneously produce reciprocating relative rotation, so that the spraying unit 37 discharges the paint from the nozzle 39 through the hose 38, and the nozzle 39 follows the T-frame 314 to perform a circular swinging motion to spray the medical device shell on the moving placement plate 17.

[0032] The paint mist and fine particles generated during the spraying process are drawn onto the water curtain plate 44 by the counter-revolving and rotating fan 215, which can increase the fluidity and rotational force of the air in multiple directions, making it easier for the paint mist and fine particles to be drawn into the water curtain area, thereby preventing the paint mist from flowing back and adhering to the equipment or product to cause secondary pollution, keeping the product surface clean, reducing pollution, and ensuring the quality and consistency of the spraying effect.

[0033] After the painting process, the conveyor belt assembly 16 moves the painted placement plate 17 and the medical device shell to the dryer for drying.
