[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-2 This utility model provides a technical solution: an online cleaning device for plastic parts after assembly, comprising:

[0028] Turntable 1 is fixedly installed on the output shaft of the divider. Several positioning fixtures 11 are arranged circumferentially on the turntable 1. The parts to be cleaned are placed on the positioning fixtures 11. The turntable 1 is provided with through holes 12 corresponding to the positions of the positioning fixtures 11.

[0029] The dust collection module 2 includes a column 21, a sliding cylinder 22, a mounting bracket 23, a baffle 24, a dust collection hopper 25, an air pipe 26, a vacuum gun 27, and a static eliminator 28. The sliding cylinder 22 is fixedly mounted on the column 21, the mounting bracket 23 is fixedly mounted on the push plate 221 of the sliding cylinder 22, the baffle 24 is fixedly mounted on the mounting bracket 23, and the bottom of the baffle 24 has an opening. When the baffle 24 moves down and snaps onto the surface of the turntable 1, the positioning fixture 11 is covered inside the baffle 24. The dust collection hopper 25 is positioned below the baffle 24, and the top opening of the dust collection hopper 25 is located below the turntable 1. One end of the air pipe 26 is connected to the dust collection hopper 25, and the other end is connected to the vacuum gun 27. The static eliminator 28 is fixedly mounted on the column 21, and the static eliminator 28 faces the positioning fixture 11.

[0030] After the static electricity of the parts to be cleaned is eliminated by the static eliminator 28, the parts are then vacuumed online by the vacuum gun 27, which effectively improves the dust removal efficiency and ensures the surface cleanliness of the parts before they are unloaded.

[0031] The dust collection hopper 25 is fixedly installed on the support base 251, and the support base 251 is fixedly installed on the column 21, effectively ensuring that the dust collection hopper 25 and the baffle 24 are in the same position.

[0032] Working principle: The positioning fixture 11 positions the part to be cleaned by contour positioning. When the turntable 1 drives the part to be cleaned on the positioning fixture 11 to rotate to below the cover 24, the static eliminator 28 eliminates the static electricity generated by the assembly of the part to be cleaned. Then, the cover 24 moves down under the drive of the slide cylinder 22. The cover 24 moves down and locks onto the surface of the turntable 1, covering the positioning fixture 11 and the part to be cleaned on it. Then, the vacuum gun 27 is started, and negative pressure suction is generated in the air pipe 26, so that the dust on the surface of the part to be cleaned falls from the through hole 12 on the turntable 1 to the dust collection hopper 25, and is collected by the vacuum gun 27 through the air pipe 26.

[0033] Example 2

[0034] Based on the above embodiments, this embodiment further improves upon the following technical solution: the end of the air tube 26 is fixed to the bottom connector tube of the dust collection hopper 25 by a hose clamp, effectively preventing the end of the air tube 26 from detaching from the bottom connector tube of the dust collection hopper 25.

[0035] Example 3

[0036] Based on the above embodiments, this embodiment further improves upon the following technical solutions: a limit seat 222 is provided on the slide cylinder 22, a limit block 2211 with a position corresponding to the limit seat 222 is provided on the push plate 221, and a buffer 2221 is provided on the limit seat 222.

[0037] When the push plate 221 drives the mounting bracket 23 and the baffle 24 downward, the buffer 2221 on the limit seat 222 is squeezed by the limit block 2211. The buffer 2221 absorbs the impact energy of the mounting bracket 23 and the baffle 24 downward, and avoids the baffle 24 from colliding and being damaged with the turntable 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
