Description

Technical Field

[0001] The invention relates to the technical field of hot stamping of clothing patches, in particular to a hot stamping machine for clothing patches with high material placement accuracy. Background Art

[0002] In the process of jersey production, it is necessary to make numbers, team player name characters and badge LOGO on jersey cut pieces or finished jerseys. The production methods can be printing, embroidery, font hot stamping, etc. Among them, the font hot stamping method can use a variety of materials and processes such as lettering film, silicone, heat transfer, printing and embroidery composite craft badges to meet the needs of different usage scenarios. The font hot stamping method is generally that the back of the fonts of various materials has adhesive. After the fonts are arranged on the clothes, the fonts are bonded to the clothes through hot pressing on the pressing platform. At present, during the production of font hot stamping, the production staff will select the corresponding fonts and arrange them in a specific position on the clothes according to the design requirements, or first arrange the fonts on a transfer film and then place them on the clothes as a whole, and then place them on the pressing platform for hot pressing. After the hot pressing is completed, the auxiliary film is torn off, and the clothes are completed. Because the numbers and team player names of jerseys are generally personalized, in actual production, the production staff selects the corresponding designed characters from the numbers and letters, and the process of arranging these characters according to the design requirements requires complex manual processing. Therefore, we designed an automatic hot stamping machine for clothing patches. Through the cooperation of motion control modules, material bins and software, it can automatically extract the required characters from the material bin according to the layout design, automatically place them in specific positions on the clothes and complete the hot stamping, thus realizing the fully automated hot stamping production of personalized character patch jerseys. This production method can be applied to the batch automated production of patch hot stamping clothing in engineering projects, and can also be applied to offline personalized customized patch hot stamping clothing production in commercial environments such as shopping malls and football match sites. It can also cooperate with e-commerce sales systems to realize C2M production and sales of patch hot stamping clothing.

[0003] Existing hot stamping of character molds generally adopts manual material placement and manual pressing methods. For badge characters of single components, the production staff generally first lays the cut pieces or ready-made clothes (collectively referred to as garment pieces) on the pressing platen, uses laser lines, projections or paper pattern templates to position them on the garment pieces, and the production staff places the patches on the garment pieces according to the positioning marks and completes the pressing. For products with multiple characters (patch components), the patch components are generally arranged on a sticky transfer film to form a whole, and then the patch combination combined on the transfer film is placed on the clothes for pressing. When arranging the patches on the transfer film, in order to ensure the accurate relative position of the patches, it is necessary to map the patch outline onto the transparent transfer film by projection or backlighting, and the production staff places the patches according to the outline position to ensure the accurate position of the patches. The existing technology completely relies on manual material picking and placing, which has low production efficiency, and the accuracy of the material placement position is completely dependent on manual operation, with low positioning accuracy and poor product consistency. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a clothing patch hot stamping machine with high material placement accuracy. When hot stamping patches, any character in the material bin can be automatically grabbed by a mechanical arm. Since a plurality of suction cups are arranged at the grabbing position of the mechanical arm, the mechanical arm can grab materials of different sizes and shapes. A material picking and positioning camera is arranged on the suction cup to take photos of the patches in the material bin. The angle and position compensation when placing the patches to be grabbed can be determined by a visual processing algorithm. The visual positioning function of the material picking and positioning camera can reduce the requirements for adjusting the position of the material bin, and at the same time can compensate for the error of the position of the patches in the material bin, and enhance the adaptability to different patch products. At the same time, the material picking and positioning camera can detect and adjust the placement angle and position of the patches grabbed by the mechanical arm, which is controlled by a program. The robot arm automatically places the patch at the predetermined position, and the material positioning camera is set on the ironing table to shoot the garment pieces, marks and patches placed on the table. The material positioning camera can shoot the marks on the garment pieces to determine the placement of the patches. At the same time, after the patches are placed, it can ensure that the placement of the patches is accurate. The motion control module, material bin and software can be used to automate the grabbing and placement of patches, which improves production efficiency and improves the accuracy and consistency of patch placement. In particular, it can automatically arrange the 26 letters, 10 numbers and other LOGO badges according to the program, which solves the problem of personalized production of jersey numbers and names, and solves the problem of low production efficiency of manual material placement and material picking.
