Description

Technical Field

[0001] This utility model relates to the technical field of pattern position detection devices, specifically a pattern position detection device for garment production processes. Background Technology

[0002] Before printing on clothing, a pattern position detection device is needed to ensure printing accuracy. The device moves an industrial camera by laying the clothing flat on a conveyor belt and using a three-axis slide table. The captured image is compared with a preset CAD template (using OpenCV's SIFT feature point matching algorithm). The offset is calculated, and the deviation between the actual and theoretical positions of the pattern is calculated using a coordinate transformation matrix. If a position offset is detected (e.g., +1.2mm in the X direction), the PLC controls the robotic arm to adjust the positioning coordinates of the printing machine in the next process to achieve dynamic compensation.

[0003] However, existing pattern position detection devices do not have auxiliary components to eliminate wrinkles in moving clothing. Once wrinkles appear on clothing, they will cause pattern deformation and misalignment geometric distortion. The uneven surface formed by wrinkles will cause uneven contact between the screen and the fabric during screen printing, differences in ink penetration depth (local offset can reach 1-3mm), and fluctuations in printhead height (±0.5mm) during digital direct printing, which will cause deviations in ink droplet flight trajectory and thus reduce printing quality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pattern position detection device for garment production processes. It solves the problem that existing pattern position detection devices lack auxiliary components for wrinkle removal on moving garments. Wrinkles on garments lead to pattern deformation and geometrical distortion, and the uneven surface created by wrinkles causes uneven contact between the screen and fabric during screen printing, resulting in differences in ink penetration depth (local deviations of 1-3mm) and printhead height fluctuations (±0.5mm) during digital direct printing, causing deviations in ink droplet flight trajectories and ultimately reducing printing quality.

[0010] A heating plate is fixedly installed inside the pressure plate;

[0011] Two guide rods are fixedly connected to the upper surface of the pressure plate, and the upper ends of the two guide rods slide through the upper surface of the second concave frame.

[0012] Preferably, the auxiliary component further includes four second cylinders, which are respectively fixedly mounted on the lower surfaces of the two fixed plates;

[0013] Each of the four second cylinders has an L-shaped connecting plate fixedly connected to its telescopic end, and two concave plates are provided on the opposite sides of the two fixed plates.

[0014] Preferably, the lower ends of the four L-shaped connecting plates are fixedly connected to the upper surfaces of the corresponding concave plates, and multiple auxiliary rollers are rotatably connected to the concave parts of the two concave plates.

[0015] Preferably, the auxiliary component further includes a first concave frame, which is fixedly connected to the upper surface of the two fixed plates;

[0024] 1. The pattern position detection device used in this garment production process has a lower surface of the pressure plate in contact with the upper surface of the garment.

[0025] 2. The pattern position detection device used in this garment production process uses two dust pumps to suck dust passing over the surface of the garment into the dust collection box through two connecting pipes and a dust collection box.

[0033] The telescopic end of the first cylinder 3 slides through the lower surface of the second concave frame 10, and a pressure plate 17 is fixedly connected to the telescopic end of the first cylinder 3. The interior of the pressure plate 17 is hollow.

[0034] A heating plate is fixedly installed inside the pressure plate 17;

[0035] Two guide rods 4 are fixedly connected to the upper surface of the pressure plate 17, and the upper ends of the two guide rods 4 slide through the upper surface of the second concave frame 10.

[0036] Furthermore, the auxiliary assembly also includes four second cylinders 9, which are respectively fixedly mounted on the lower surfaces of the two fixed plates 1;

[0037] Among them, the telescopic ends of the four second cylinders 9 are all fixedly connected with L-shaped connecting plates 8, and the opposite surfaces of the two fixed plates 1 are provided with two concave plates 7.

[0038] Furthermore, the lower ends of the four L-shaped connecting plates 8 are fixedly connected to the upper surfaces of the corresponding concave plates 7, and multiple auxiliary rollers 12 are rotatably connected to the concave parts of the two concave plates 7.

[0039] Furthermore, the auxiliary component also includes a first concave frame 6, which is fixedly connected to the upper surfaces of the two fixed plates 1;

[0042] Furthermore, two connecting plates 14 are fixedly connected to the concave part of the first concave frame 6, and a dust collection box 13 is fixedly connected to the opposite side of the two connecting plates 14.

[0045] Furthermore, a conveying mechanism 2 is fixedly installed on the opposite surfaces of the two fixed plates 1.

[0046] Furthermore, when using the pattern position detection device for garment production process, the garment is first placed under multiple auxiliary rollers 12, and then four second cylinders 9 are activated.

[0050] The lower surface of the pressure plate 17 contacts the upper surface of the garment. With the help of multiple auxiliary rollers 12, the texture of the pressure plate 17 conforms to the texture of the garment, thereby eliminating wrinkles and improving the quality of subsequent printing.

[0051] The process then involves activating an industrial camera and comparing the captured images with a preset CAD template (using OpenCV's SIFT feature point matching algorithm).

[0052] Offset calculation: The deviation between the actual position and the theoretical position of the pattern (X / Y direction offset and rotation angle) is calculated by using the coordinate transformation matrix.

[0054] If a positional offset is detected (e.g., +1.2mm in the X direction), the PLC controls the robotic arm to adjust the positioning coordinates of the printing machine in the next process to achieve dynamic compensation.
