[0029] After the first photoelectric sensor 113 senses that the airbag bag to be covered with ink is in place, a start signal is sent to the intelligent single-chip controller, and the intelligent controller outputs a signal to the motion control card module. The motion control card module outputs a pulse signal to control the movement of the X-axis servo motor 102 and the Y-axis servo motor, and also gives a printing signal to the printing component 106, so that the printing component 106 sprays out the desired effect graphics; secondly, a laser displacement ranging sensor 112 is set to identify the thickness of the airbag bag placed on the tray 109 material transport component, so that the Z-axis displacement component can adjust the inkjet height of the printing component 106 according to the identified thickness.

[0030] Furthermore, the UV inkjet device also includes:

[0031] Suction cup 202 area 2, the suction cup 202 area 2 is located at the rear end of the inkjet area 1, the suction cup 202 area 2 includes a suction cup 202, a laser sensor 203, a second photoelectric sensor 204 and a plasma wind rod 201, the laser sensor 203 is used to detect the thickness of the airbag sucked up by the suction cup 202, the second photoelectric sensor 204 is used to sense whether the suction cup 202 and the airbag are tightly sucked, the plasma wind rod 201 is installed on the left and right sides of the suction cup 202 area 2, and the plasma wind rod 201 is used to eliminate static electricity for the airbag transported from the inkjet area 1 to the suction cup 202 area 2.

[0032] By setting a laser sensor 203 in area 2 of the suction cup 202, it is ensured that the suction cup 202 does not adsorb too much or too little airbag. Secondly, by setting a second photoelectric sensor 204, the stability between the suction cup 202 and the adsorbed airbag is ensured. Finally, by setting a plasma wind rod 201, when the pallet 109 material transport component moves to area 2 of the suction cup 202, the static electricity of the airbag on the pallet 109 material transport component can be eliminated, thereby avoiding the situation where the suction cup 202 adsorbs too much airbag due to static electricity.

[0033] Furthermore, the tray 109 material transport assembly includes a material transport track 110, a tray 109 and a clamping slider 111. The material transport track 110 is arranged on the left and right sides of the inkjet area 1 and the suction cup 202 area 2.

[0035] Furthermore, the X-axis displacement assembly includes an X-axis guide rail 101 and an X-axis servo motor 102. The X-axis guide rail 101 is provided with two groups, and the two groups of X-axis guide rails 101 are respectively located on the left and right sides of the inkjet area 1.

[0036] Furthermore, the Y-axis displacement assembly includes a Y-axis guide rail 104, a Y-axis servo motor and a Y-axis guide seat 105, the two ends of the Y-axis guide rail 104 are respectively fixed on the two groups of X-axis guide seats 103, the Y-axis guide seat 105 is installed on the Y-axis guide rail 104, and the Y-axis servo motor is used to drive the Y-axis guide seat 105 to move along the Y-axis guide rail 104.

[0039] Furthermore, UV lamps and air cooling components are also provided on both sides of the inkjet printer head of the printing component 106.

[0040] By setting up a UV curing lamp, the ultraviolet light emitted by the UV curing lamp is used to cure the ink. The air-cooling component uses suction cooling and uses air as the cooling medium. The high-speed flowing air directly takes away the heat of the high-temperature UV curing lamp, avoiding the UV curing lamp from overheating and affecting the airbag.

[0041] Furthermore, the UV inkjet device further comprises: a display screen and a distribution box, the display screen is an industrial computer touch screen 4, and the display screen can set operation operations and related data;

[0042] The distribution box is used to provide power to the entire UV inkjet device. A control component is arranged in the distribution box. The control component includes an intelligent single-chip microcomputer controller and a motion card module. The intelligent single-chip microcomputer controller is wirelessly connected to the motion card module. The motion card module is wirelessly connected to the tray 109 material transport component, the X-axis displacement component, the Y-axis displacement component and the Z-axis displacement component.

[0043] In this embodiment, the printing component 106 includes an inkjet printer and a negative pressure box. The working trigger signal of the print head inkjet is controlled by the inkjet printer and the negative pressure box, and the inkjet printer and the negative pressure box are electrically connected to the control component. The trajectory of the print head inkjet operation will be displayed on the industrial touch screen 4 through the control component; secondly, in this embodiment, the UV inkjet device is also provided with a three-color warning light 3, and the three-color warning lights 3 are red, yellow and green, respectively, wherein the red light represents abnormal operation of the equipment, the yellow light represents that the equipment is in standby state, and the green light represents that the equipment is in normal operation.

[0044] By displaying the running track of the nozzle on the industrial touch screen 4 and giving a signal to the warning light according to the running path result, it is more intuitive to help the operator to spray the ink dots normally, so as to speed up the production rhythm and improve the production quality.

[0045] Working principle of the present invention:

[0046] First, select the corresponding product mode on the touch screen 4 and set the parameters, then stack the airbag bags to be covered with ink or drawn with thick solid lines on the pallet 109 material transport component. After the first photoelectric sensor 113 senses that the airbag bag is in place, it sends a signal to the single-chip controller, and the single-chip controller gives a start trigger signal to the motion control card to move the laser displacement ranging sensor 112 to the position of the airbag bag for thickness detection. Then the laser displacement ranging sensor 112 generates a signal to the single-chip controller, and the single-chip controller sends a signal to the motion control card to make the Z-axis servo motor 108 automatically drop to an appropriate height according to the result of the laser displacement ranging sensor 112. Then the motion control card gives a pulse signal to the X-axis servo motor 102 and the Y-axis servo motor respectively, prompting them to move to the appropriate position. At the same time, the pulse signal given by the motion control card to the X-axis servo motor 102 and the Y-axis servo motor will also indirectly give the printing component 1 06 a pulse signal, prompting the printing component 106 to spray ink. When the printing component 106 is spraying ink, the printing device will also give a pulse signal to the UV lamp and the air cooling component to light up the UV lamp to irradiate and cure the inkjet pattern. When the X-axis servo motor 102 and the Y-axis servo motor complete the path, it is equivalent to the printing component 106 spraying the pattern. Then the Z-axis servo motor 108 will automatically rise, and the tray 109 material transport component will be pushed to the suction cup 202 area 2 for sucking the sheet. When the tray 109 material transport component is transported to the suction cup 202 area 2, the plasma wind rod 201 starts to work, and then the inkjet image of the airbag bag is further cured. Then the suction cup 202 adsorbs the airbag bag on the tray 109 material transport component. During the adsorption process, the laser sensor 203 will sense and detect whether the airbag bag is sucked up too much, and the second photoelectric sensor 204 will sense and detect whether the airbag and the suction cup 202 are firmly adsorbed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
