DETAILED DESCRIPTION

[0015] In order to facilitate the understanding of those skilled in the art, the following will be combined with the embodiments and the drawings of the utility model Figure 1-3 Further description of the utility model, the content mentioned in the implementation manner is not the limitation of the utility model.

[0016] See Figure 1-3An online plasma cleaning device includes a rotary disk printing machine 1, which includes a rotary disk 11, a plurality of carrier mechanisms 12 for placing glass in a circular array on the rotary disk 11, a dust removal mechanism 13 for removing dust from the glass on the carrier mechanism 12, a printing mechanism 14 for printing on the glass on the carrier mechanism 12, and a loading and unloading mechanism 15 for placing glass into or removing glass from the carrier mechanism 12. A plasma cleaning mechanism 16 for cleaning the glass on the carrier mechanism 12 is installed on the dust removal mechanism 13, and the plasma cleaning mechanism 16 includes a plasma generator 161 and a plasma spray gun 162 connected to the plasma generator 161. The rotary disk printing machine 1 also includes a PLC controller 17, which is electrically connected to the plasma generator 161, the dust removal mechanism 13, the printing mechanism 14, and the loading and unloading mechanism 15 respectively.

[0017] The online plasma cleaning device of the present invention installs a plasma cleaning mechanism 16 for cleaning glass on the dust removal mechanism 13 of the existing rotary printing press 1. In conjunction with the PLC controller 17 of the rotary printing press 1, the plasma cleaning treatment is performed on the glass after dust removal, thereby enhancing the surface adhesion of the glass IR hole and the surrounding area. At the same time, the plasma cleaning mechanism 16 adopts an embedded design, which does not affect the printing press cycle, does not increase the equipment space, and does not increase additional labor costs.

[0018] In this embodiment, the carrier mechanism 12 includes vacuum adsorption holes 121 formed on the rotating disk 11. The vacuum adsorption holes 121 are used to adsorb and fix the glass.

[0019] In this embodiment, the carrier mechanism 12 further includes a plurality of strip-shaped fixing holes 122 formed around the vacuum suction hole 121. Each strip-shaped fixing hole 122 includes movable fixing claws 123. The eight-claw fixing mechanism, comprised of the multiple fixing claws 123, is used to clamp the glass from all sides after loading and release it for unloading.

[0020] In this embodiment, the dust removal mechanism 13 includes a sticky roller 131 for removing dust from the glass on the carrier mechanism 12, and a transverse movement bracket 132 for driving the sticky roller 131 to move laterally. The plasma spray gun 162 is mounted on the transverse movement bracket 132. As the dust removal mechanism 13 operates, the plasma generator 161 automatically activates, and the plasma spray gun 162 emits flames and performs transverse cleaning. Upon completion, the plasma generator 161 automatically shuts down, and the flame of the plasma spray gun 162 automatically extinguishes. This cycle repeats, automatically completing the plasma cleaning process for each piece of glass.

[0021] In this embodiment, the loading and unloading mechanism 15 is a multi-axis manipulator.

[0022] In this embodiment, the rotary printing press 1 further includes a platform 10 and a positioning mechanism 18 disposed on the platform 10 for positioning the glass on the carrier mechanism 12. The positioning mechanism 18 is electrically connected to the PLC controller 17. The loading and unloading mechanism 15, the positioning mechanism 18, the plasma cleaning mechanism 16, and the printing mechanism 14 are sequentially arranged around the rotating disk 11 in a clockwise or counterclockwise direction. The positioning mechanism 18 uses a camera to capture images and calculates the coordinates of the glass to be placed. The printing mechanism 14 automatically compensates for the position based on the coordinates calculated by the positioning mechanism 18 before printing. The loading and unloading mechanism 15 uses a multi-axis robot to place the glass to be printed on the carrier mechanism 12. The glass is then sequentially cleaned using a plasma spray gun 162 in a clockwise or counterclockwise direction, positioned by the positioning mechanism 18, and printed by the printing mechanism 14. The printed glass is then removed from the carrier mechanism 12. The dust removal mechanism 13, printing mechanism 14, loading and unloading mechanism 15 and positioning mechanism 18 adopted in the present invention are all conventional technologies in the field and will not be described in detail here.

[0023] The working principle of the online plasma cleaning device of the utility model is:

[0024] 1) Select the required plasma specifications according to the plasma cleaning effect and site conditions;

[0025] 2) Design the corresponding plate reinforcement required to fix the plasma spray gun 162 according to the dust removal mechanism 13 inside the rotary printing press 1;

[0026] 3) Install the plasma generator 161 and the plasma spray gun 162, and connect the PLC signal corresponding to the printing mechanism 14 to the plasma generator 161 to control its start and stop actions.

[0027] 4) The printing press is started normally, the plasma spray gun 162 moves back and forth accompanied by the dust removal action, and the plasma generator 161 is started or stopped according to the PLC signal, completing the plasma cleaning of each piece of glass.

[0028] The online plasma cleaning device of the utility model only needs to perform normal printing startup and machine adjustment actions, and will not increase the work intensity due to the addition of plasma cleaning actions.

[0029] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
