Description

Technical Field

[0001] This utility model belongs to the field of automotive painting technology, and specifically relates to an electrostatic adsorption device for paint mist in automotive painting robots. Background Technology

[0002] Automotive painting is a crucial process in automobile manufacturing, primarily used to protect the metal substrate of the car body, enhance its appearance, and provide weather resistance and corrosion protection. Modern automotive painting largely relies on painting robots, whose multi-dimensional operating structures drive the spraying mechanism to atomize and spray the paint. However, during this atomization process, not all paint mist adheres to the car's surface; some remains suspended in the air, polluting the workshop air, harming operator health, and violating environmental regulations. Therefore, adsorption devices are used to collect this paint mist. Since the mist contains paint particles that haven't adhered to the car body, adsorption allows for their recycling and reuse, reducing paint waste. This is particularly effective for metallic and specialty paints, significantly saving costs. Electrostatic adsorption of paint mist is a commonly used method for collecting paint mist. However, in existing technologies, most electrostatic adsorption devices for paint mist collect paint mist by using a single set of fixed plates. After prolonged use, the plates (dust collection plates) are easily covered by paint mist (adhered dried / semi-dried paint film), requiring frequent shutdowns for manual cleaning, which affects the continuity of production.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

The connecting pipe assembly includes a connecting pipe body, a reducing pipe, and a perforated plate. The reducing pipe is fixedly connected to the left side of the connecting pipe body.

[0013] In a preferred embodiment, the inner diameter of the connecting pipe body is larger than that of the reducing pipe, and a set of flanges is fixedly connected to the right end of the connecting pipe body and the left end of the adsorption inlet pipe.

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.

[0026] Please see Figures 1-3 As the first embodiment of this utility model:

[0027] An electrostatic adsorption device for paint mist in an automotive painting robot includes: an electrostatic adsorption component 100, which includes a central pipe seat 101, a switching shaft 107, a switching telescopic rod 108, an electrode plate 111, a cleaning motor 114, and a cleaning frame 115.

[0028] A set of switching shafts 107 for switching the left and right side plates 111 is rotatably connected to the center position of the inner side of the central pipe seat 101 in the front-back direction. A set of switching telescopic rods 108 are fixedly connected to both the left and right sides of the switching shafts 107. A plate seat 109 is fixedly connected to the end of the switching telescopic rods 108 away from the center of the central pipe seat 101.

[0033] An inner sealing ring 110 is fixedly connected to the side of the electrode plate seat 109 away from the center of the central pipe seat 101. The inner sealing ring 110 and the inner sealing ring groove 113 are mutually sealed and fitted. A switching motor is fixedly connected to the front side of the switching shaft 107 through a coupling. The switching motor drives the switching shaft 107 to complete the position exchange of the left and right switching telescopic rods 108, thereby realizing the position exchange of the electrode plates 111 on both sides, and causing the switching telescopic rods 108 to drive the electrode plate seat 109 to move left and right to assist in the position exchange.

[0034] The lower end of the inner side of the cleaning pipe 103 is provided with a receiving groove 116 located on the right side of the right end annular groove 112.

[0035] Specifically, the left electrode plate 111 is a component used for electrostatic adsorption of paint mist.

The reducing pipe 202 is fixedly connected to the left side of the connecting pipe body 201.

A set of flanges 105 are fixedly connected to the right end of the connecting pipe body 201 and the left end of the adsorption inlet pipe 102. A set of connecting sealing ring grooves 204 are opened on the opposite face of the two sets of flanges 105.

[0040] After the two sets of flanges 105 are spliced, the two ends of the sealing ring 106 are sealed and fitted with the connecting sealing ring groove 204. The inner side of the right side of the connecting pipe body 201 is also provided with an installation groove. A perforated plate 203 for reducing wind speed is installed in the installation groove. The connecting pipe assembly 200 is installed to the left side of the adsorption inlet pipe 102, so that the reducing pipe 202 first completes the adsorption guidance, the wind speed is reduced in the connecting pipe body 201, and the wind speed is reduced again by the perforated plate 203.

[0041] Based on the first embodiment described above, the connecting pipe assembly 200 is further installed on the left side of the adsorption inlet pipe 102 and connected via flange 105. During the connection, the sealing ring 106 and the connecting sealing ring groove 204 are fitted together to improve the connection sealing performance. This allows the variable diameter pipe 202 to complete the adsorption guidance first, and the wind speed is reduced within the connecting pipe body 201. The wind speed is further reduced by the perforated plate 203, which prolongs the time for the paint mist to pass through the electrode plate 111, thereby improving the paint mist treatment effect of the electrode plate 111.
