Description

Technical field:

[0001] The utility model relates to the technical field of screen printing blanking devices, in particular to a screen printing blanking device for plastic sheets. Background technology:

[0002] In the screen printing production line, manual unloading of substrates such as plastic sheets after screen printing is adopted, which is not only labor-intensive but also inefficient. Therefore, it is necessary to set up a screen printing unloading device to automatically unload the substrates after screen printing.

[0003] Most of the existing plastic sheet screen printing blanking devices only include a lifting slide that is slidably connected to the top of the carrier plate located on the blanking station in the vertical direction, a lifting power mechanism for driving the lifting slide to slide, and four suction nozzles arranged at the four corners of the bottom of the lifting slide. In order to ensure the printing quality of the substrate, most of them need to provide an adhesive layer on the carrier plate for placing the substrate to prevent the substrate from shifting during printing. In order to ensure that the substrate can be firmly positioned on the carrier plate, the adhesive layer needs to have a high viscosity. Accordingly, the adhesive layer with a high viscosity will bring difficulties to the blanking of the substrate, especially the middle part of the substrate is not easy to separate from the adhesive layer, and the middle part of the substrate is not suitable for adsorption by setting a suction nozzle. That is, when the existing plastic sheet screen printing blanking device adsorbs and discharges the substrate, it is easy to fail to complete automatic blanking normally because the middle part of the substrate is firmly adhered to the adhesive layer. Not only does it often require manual intervention, but it also affects the overall screen printing efficiency and is extremely inconvenient to use. Utility model content:

[0004] The purpose of the utility model is to provide a plastic sheet screen printing unloading device to address the deficiencies in the prior art. The device can reliably and stably unload plastic sheets and other printing substrates automatically, avoid the situation in which manual intervention is often required in the past, ensure the overall screen printing efficiency, and be better suitable for automatic unloading of plastic sheets and other printing substrates.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a plastic sheet screen printing blanking device, including a transfer device, and also including a blanking rack arranged on the output end of the transfer device, a lifting module arranged on the blanking rack, and a horizontal shovel module arranged on the blanking rack. The lifting module includes a lifting slide connected to the blanking rack in a vertical direction, a lifting power mechanism for driving the lifting slide to slide, and a plurality of suction nozzles arranged on the bottom of the lifting slide. The horizontal shovel module includes a blade connected to the blanking rack in a horizontal direction, and a horizontal shovel power mechanism for driving the blade to slide.

[0006] A further improvement to the above solution is that the unloading rack includes a horizontal plate arranged on the output end of the transfer device and two vertical plates respectively arranged at both ends of the horizontal plate.

[0007] A further improvement to the above scheme is that the lifting power mechanism is arranged at the middle position of the horizontal plate of the unloading rack, and the output end of the lifting power mechanism is driven and connected to the middle position of the lifting slide.

[0008] A further improvement to the above solution is that the horizontal shovel power mechanism is arranged between the bottoms of the two vertical plates of the unloading rack, and the output end of the horizontal shovel power mechanism drives the connected shovel blade.

[0009] A further improvement to the above solution is that the cross-shovel power mechanism is a rodless cylinder.

[0010] A further improvement to the above solution is that there are four suction nozzles, which are respectively arranged at four corners of the bottom of the lifting slide.

[0011] A further improvement to the above scheme is that the transfer device includes a Z-axis running mechanism having a Z-axis running track, and the transfer device also includes an X-axis running mechanism having an X-axis running track and / or a Y-axis running mechanism having a Y-axis running track.

The nozzle 33 absorbs the substrate to be unloaded, and then drives the lifting slide 31 to slide upward through the lifting power mechanism 32 and drives each suction nozzle 33 to move upward, and then drives the scraper 41 to slide through the horizontal shovel power mechanism 42, and the scraper 41 shovels the bottom of the substrate to separate the substrate from the carrier, and finally the substrate adsorbed on the suction nozzle 33 after separation from the carrier is transferred to the unloading position through the transfer device 1, completing the unloading process of the entire substrate; the utility model can ensure that the substrate can be stably separated from the carrier every time, and there is no situation where the substrate cannot be adsorbed, and can reliably and stably unload substrates such as plastic sheets automatically, and can avoid the situation where manual intervention is often required in the past.

[0018] The lifting power mechanism 32 is arranged at the middle position of the horizontal plate 21 of the unloading rack 2, and the output end of the lifting power mechanism 32 is driven to connect to the middle position of the lifting slide 31, so that the whole lifting process is smoother, so that the printing material can be better adsorbed and unloaded; the horizontal shovel power mechanism 42 is arranged between the bottoms of the two vertical plates 22 of the unloading rack 2, and the output end of the horizontal shovel power mechanism 42 is driven to connect to the shovel 41. The horizontal shovel power mechanism 42 is a rodless cylinder, which not only has a larger stroke, but also has a more compact and reasonable overall structure.

[0019] There are four suction nozzles 33, and the four suction nozzles 33 are respectively arranged at the four corners of the bottom of the lifting slide 31; the four ends of the substrate to be unloaded are adsorbed by the four suction nozzles 33, and as the lifting power mechanism 32 drives the lifting slide 31 to slide upward, the four ends of the substrate to be unloaded are lifted upward, and then the horizontal shovel power mechanism 42 drives the scraper 41 to shovel the bottom of the substrate to be unloaded. Under the shoveling action of the scraper 41, the middle part of the substrate can be completely separated from the carrier plate, thereby facilitating the unloading of subsequent substrates.

[0020] The transfer device 1 includes a Z-axis running mechanism 11 having a Z-axis direction running track, and the transfer device 1 also includes an X-axis running mechanism 12 having an X-axis direction running track and / or a Y-axis running mechanism 13 having a Y-axis direction running track; the transfer device 1 in this embodiment includes a Z-axis running mechanism 11 having a Z-axis direction running track, an X-axis running mechanism 12 having an X-axis direction running track, and a Y-axis running mechanism 13 having a Y-axis direction running track, and can transfer the printing material in three directions of X, Y, and Z.
