Problems solved by technology

The main defect of the current sewing method is that the shape of the collar will be deformed before sewing due to the deformation of the fabric and the quality of the workers.
There will be two serious problems: 1) the stitches are sewn outside the collar
2) The sewing path is not parallel to the edge of the collar, which seriously affects the appearance

Embodiment 1

[0086] Embodiment 1, with reference to attached Figure 5-8 , 11.

[0087] This embodiment provides an intelligent sewing device based on machine vision, including:

[0088] 1. The sewing machine control device is used to control the sewing action and sewing path of the sewing machine; the control device is not shown in the figure, and the control device only needs to receive the control signal and issue a control command according to the control signal. The control device can be purchased from existing The control chip or CPU or other processors.

[0089] 2. The sewing machine is connected to the sewing machine control device through wired or wireless data, and can perform sewing operations under the control of the sewing machine control device. The improvement point of the present invention is that the sewing machine with industrial control has similar products in the prior art. Therefore, the present invention can be realized by using the sewing machine in the prior art. ...

Embodiment 2

[0149] Embodiment 2, with reference to attached Figure 14-16 .

[0150] The collar sewing device of the present invention includes a workbench 1 with a smooth surface. The workbench 1 is made of stainless steel and has a smooth surface, which facilitates the movement of the collar and does not scratch the cloth, especially the cloth to be processed.

[0151] There is a storage area and a sewing area on the workbench 1. The storage area and the sewing area are two different work areas. This division is mainly because the acquisition of images and the specific execution of sewing operations need to be in two different places, so this division, In fact, the storage area and the sewing area are connected and integrated, and there is no need to have a clear boundary to distinguish them, as long as the collection field of view above the storage area is not blocked.

[0152] Since the collar is a very light object, a slight disturbance is likely to cause it to shift or fold over, e...

Abstract

The invention provides an intelligent sewing device based on machine vision. The intelligent sewing device comprises a sewing machine control device, a sewing machine, a first moving device, a secondmoving device, an image acquisition device, a light source and a processing device. The invention further provides an intelligent sewing method based on machine vision. A collar sewing system based onmachine vision is introduced, and a more stable system is achieved. According to the device, frequent and complicated collar path planning is omitted, and a simple calibration method is introduced. The method is more intelligent and accurate, a sewing path parallel to a collar can be automatically planned, and sewing cannot be affected after the collar is deformed. An intelligent needle adjustingalgorithm is introduced, the distance between the needles is automatically adjusted, sewing points fall on intersection points of the sewing path, and the sewn beautiful appearance of the collar is ensured. According to the device and the method, and dependence of the system on skilled operators is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent sewing based on machine vision. Background technique [0002] The stitch path for the collar should be parallel to the edge of the collar, e.g. figure 1 shown. There is currently no collar sewing equipment based on machine vision on the market. At present, according to the collar template, the sewing path of the sewing needle is planned, and then the collar is sewed according to the planned path. The main defect of current sewing method is: due to problems such as cloth deformation, worker's quality, the shape of the collar before sewing has certain deformation. Such as figure 2 , 3 As shown, there is some deformation of the collar before sewing. At this point, if you use the same path template to sew. Then there will be two serious problems: 1) the stitches are sewn outside the collar. 2) The sewing path is not parallel to the edge of the collar, which seriously affects the appearanc...
