[0002] Pad printing uses a steel gravure and a curved pad printing head made of silicone rubber material. The ink on the gravure is dipped into the surface of the pad printing head, and then pressed against the surface of the required object to print text, patterns, etc. Pad printing technology has many advantages. For example, it can adapt to objects of various shapes or sizes, including irregular and special-shaped products. The process is simple and efficient and suitable for a variety of materials.

[0037] The present invention will be further described below in conjunction with the accompanying drawings:

[0038] like Figures 1-8 As shown, the multi-angle intelligent pad printing device with self-checking function of the present invention is composed of a pad printing frame 100 and an intelligent pad printing component installed in the pad printing frame 100;

[0039] The intelligent pad printing assembly consists of a three-axis moving mechanism 200, a calibration pad printing rubber head mechanism 300, a pad printing ink cartridge mechanism 400, a material unloading platform mechanism 500, a multi-angle material carrying mechanism 600, a double-station unloading mechanism 700, and a visual inspection mechanism 800. The calibration pad printing rubber head mechanism 300 and the visual inspection mechanism 800 are both installed on the three-axis moving mechanism 200 and are used to detect the materials transported by the multi-angle material carrying mechanism 600 and perform multi-angle intelligent pad printing. The calibration pad printing rubber head mechanism 300 has a calibration function, and the origin calibration is performed before each use to improve the accuracy of each pad printing.

[0040] The multi-angle material carrying mechanism 600 consists of a carrying rail frame 601 and a multi-angle carrying platform 605 slidably mounted on the carrying rail frame 601. The multi-angle carrying platform 605 realizes material transportation by sliding under the double-station unloading structure 700 and the calibration pad printing rubber head mechanism 300, and is used to carry materials for multi-angle transformation to realize multi-angle pad printing.

[0041] like Figures 1-8 As shown, the present invention also discloses the following multiple more optimized specific structures:

[0042] The three-axis moving mechanism 200 is composed of a horizontal rail 202, a vertical rail 203 slidably mounted on the horizontal rail 202, a mobile frame 208 slidably mounted on the vertical rail 203, and a vertical rail 204 slidably mounted on the side of the mobile frame 208. The visual inspection mechanism 800 is mounted on the side of the vertical rail 204, and the calibration pad printing rubber head mechanism 300 is mounted on the bottom of the vertical rail 204. The visual inspection mechanism 800 can automatically inspect the products after pad printing and provide real-time feedback on the quality of the products. In this way, poor pad printing or deviation can be quickly discovered, and pad printing parameters can be adjusted in time to ensure stable product quality. The parameters can be adjusted intelligently. According to the self-inspection results, the equipment can intelligently adjust parameters such as pad printing force and ink concentration to adapt to different products and printing requirements, thereby improving pad printing efficiency and quality consistency. The visual inspection mechanism 800 adopts the SC3000 series visual sensor, which integrates imaging, processing, and communication. It is a more commonly used intelligent detection mechanism at present, and its structure will not be further described here.

The stable pressing frame 610 mainly presses the product on the product seat to avoid the product being unstable during the multi-angle adjustment and rotation process. When the angle adjustment is completed, the pressing cylinder 611 can be controlled to lift and the pressing frame rotating body 609 can be rotated to remove the stable pressing frame 610 from the product to facilitate pad printing.

The material is placed on the unloading platform mechanism 500 at the feed end through the material conveying trolley and the loading mechanism, and is placed on the material placement module 504 close to the outside. Then the platform bracket 503 is rotated to the inside, and the material picking fixture of the double-station unloading mechanism 700 is moved to the top of the material under the drive of the track, and the material is clamped and moved to the multi-angle material carrying mechanism 600 through the lifting and lowering of the material picking cylinder 704, and the material is placed on the product seat. At this time, the product seat is flat, and the shell is checked for flatness through the detection function of the product seat.
