DETAILED DESCRIPTION

[0028] In the embodiment, when in use, the flexible film on the resistance discharging mechanism naturally sags at the gap between the resistance discharging mechanism and the first inclined carrier plate 1, and the self weight of the flexible film between the resistance discharging mechanism and the first inclined carrier plate 1 provides a natural tension force, and the effect of straightening the flexible film by the self gravity is better than that by external force, and the flexible film is not damaged and the product is not prone to peeling and deviation. The vacuum generator arranged on the end of the workbench 3 provides additional vacuum suction, so that the flexible film is laid flat on the workbench 3. After being pulled by the servo material feeding channel, when the flexible film is sensed by the in-place detection mechanism to have the product thereon during movement, the servo material feeding channel stops working. Then the vacuum generator is turned on to adsorb the flexible film on the workbench, so that the flexible film is not affected by the gravity of the naturally sagging section and moves.

[0029] There are many products on the flexible film, and the sizes of the products are small. After the in-place detection mechanism detects that the product is in place, the product is ink-jetted by the ink-jet printer.

[0030] The application can keep the flexible film on the workbench in a flat state, and solves the problems of how to prevent the flexible film from being deformed during being pulled by the servo material feeding channel and how to prevent the product on the flexible film from deviating.

[0031] As a preferred mode, the resistance discharging mechanism comprises a discharging roller 4 and a discharging motor 5, the first mounting frame 6 is arranged with the discharging motor 5, the output shaft of the discharging motor 5 is coaxially fixedly connected with the discharging roller 4, and the discharging roller 4 is parallel to the upper surface of the workbench 3 and perpendicular to the connecting line segment between the resistance discharging mechanism and the damping material collecting mechanism.

[0032] After the arrangement, the discharging roller 4 is controlled to rotate by the discharging motor 5 to feed and discharge the flexible film, and the function of resistance discharging is realized. Preferably, the upper and lower portions of the flexible film discharged on the discharging roller 4 are each provided with a sensor 28 on the first mounting frame 6, the sensor 28 on the first mounting frame 6 is located between the discharging roller 4 and the left end of the first inclined carrier plate 1, and the two sensors 28 on the first mounting frame 6 are both located below and to the right of the discharging roller 4, and the two sensors 28 on the first mounting frame 6 are both signal connected with the discharging motor 5, so that when the sensor 28 above the flexible film on the first mounting frame 6 senses the flexible film, it indicates that the flexible film is tight and more discharging (flexible film) is needed, at this time, the sensor 28 above the flexible film on the first mounting frame 6 transmits a signal to the discharging motor 5, so that the discharging motor 5 drives the discharging roller 4 to rotate to discharge, thereby protecting the flexible film from being damaged and providing sufficient tension. When the sensor 28 below the flexible film on the first mounting frame 6 senses the flexible film, it indicates that the flexible film is loose and less discharging (flexible film) is needed, at this time, the sensor 28 below the flexible film on the first mounting frame 6 transmits a signal to the discharging motor 5, so that the discharging motor 5 drives the discharging roller 4 to rotate to collect.

After the detection camera A 13 detects the product on the flexible film, the detection camera A 13 sends a signal to the servo material pulling flow channel and the inkjet printer, so that the servo material pulling flow channel stops working, and the inkjet printer starts working.

[0039] After such arrangement, since the size of the product on the flexible film is small, the detection camera B 19 can shoot three rows (the queue of the rows is perpendicular to the connecting line segment between the left and right ends of the workbench 3) at a time, so that the detection camera B 19 transmits information to the mechanical arm after shooting the product, the mechanical arm drives the inkjet printer body 20 to move, and realizes inkjet printing on each row of products.
