Description

Technical Field

[0001] The present invention relates to the technical field of cloth processing equipment, and in particular to a processing device for overlapping and fixing cloth. Background Art

[0002] In modern manufacturing, the stacking and fixing of fabrics is an indispensable step in the production process of many products, especially in the fields of footwear, clothing and home textiles. For example, in footwear manufacturing, it is usually necessary to accurately overlap multiple layers of material sheets to facilitate the processing of the upper. Traditional methods of stacking and fixing fabrics mainly include stitching, hot pressing and gluing, and mechanical pressing. However, these methods have many shortcomings in practical applications, specifically: First, traditional stitching and hot pressing methods often require a long processing time, affecting the overall efficiency of the production line, especially in mass production, the efficiency bottleneck is more obvious. Secondly, in the process of stacking fabrics, the mechanical pressing method is prone to uneven distribution or position offset of fixed points, affecting the quality and consistency of the final product. Furthermore, many traditional fixing methods rely on manual operation, which makes it difficult to achieve high-precision and high-efficiency automated production, increasing labor costs and the risk of operational errors.

[0003] In recent years, ultrasonic welding technology has gradually been used in the field of textile and clothing manufacturing due to its advantages such as high efficiency, precision and low damage. Ultrasonic spot welding can generate local heat energy through high-frequency vibration to achieve rapid fixation of fabrics without the use of additional adhesives, which is environmentally friendly and cost-saving. However, there are still some technical challenges in the application of fabric stacking and fixing of existing ultrasonic spot welding equipment. Specifically, traditional ultrasonic welding equipment is difficult to achieve high-precision positioning in the process of fixing complex shapes or large-area fabrics, which affects the consistency and firmness of the welds; moreover, in actual production, the shapes and overlapping methods of fabrics are diverse, and traditional equipment is difficult to automatically adjust the welding path and welding point position according to actual conditions.

[0020] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0021] This embodiment discloses a processing device for fixing the stacked fabrics, such as fixing the stacked samples in the shoemaking process to facilitate the subsequent production of the upper. Figures 1 to 4 The processing device includes a machine platform 1, a curing head 2, a visual system and a controller 5.

[0022] The machine table 1 is provided with a working surface 10 for placing a sample to be processed, and the sample is at least two pieces of fabric stacked together.

[0023] The curing head 2 is arranged above the working surface 10 through the transfer device 3, and the transfer device 3 is used to drive the curing head 2 to move along three mutually perpendicular directions, that is, the transfer device 3 can drive the curing head 2 to move along the X-axis, Y-axis, and Z-axis in the three-dimensional space above the working surface 10.

[0024] The visual system includes a camera 40 and an image processor 41. The camera 40 is mounted above the work surface 10 and is used to obtain an image of the work surface 10. The image processor 41 is used to perform recognition processing on the image. When a sample is recognized on the work surface 10, a contour trajectory of the sample on the work surface 10 is generated based on calibration parameters, thereby obtaining the position range covered by the sample on the work surface 10. The recognition algorithm and contour trajectory generation algorithm of the image processor 41 belong to conventional technologies in the field of image processing and will not be described in detail here.

[0025] The controller 5 is connected to the image processor 41 and the transfer device 3. The controller 5 is used to generate a number of target coordinate points according to the contour trajectory, and control the movement of the transfer device 3 according to the target coordinate points, so that the curing head 2 applies curing points at different target positions of the sample, and the curing points are used to fix the superimposed fabrics at corresponding positions together.

[0026] When the processing device disclosed in this embodiment is used to stack and fix the fabric, first, two stacked samples are placed on the work surface 10. Then, after the camera 40 acquires the image of the work surface 10, the image processor 41 performs recognition processing on the image to identify the sample on the work surface 10, and generates a contour trajectory of the sample on the work surface 10 based on the calibration parameters obtained in the pre-calibration work. Then, the controller 5 processes the contour trajectory, extracts a number of position points from the contour trajectory as target coordinate points, and controls the movement of the transfer device 3 according to these target coordinate points, so as to bring the curing head 2 to the corresponding position of the sample, so that the curing head applies curing points at the positions corresponding to these target coordinate points, and fixes the stacked fabrics of the sample together through these curing points.

[0027] Thus, the sample contour trajectory is obtained through the visual system, and the controller 5 accurately generates the fixed point coordinates based on this, ensuring that the fixed points are evenly distributed and improving the fixing quality. Secondly, the transfer device 3 can move in three mutually perpendicular directions to achieve full coverage of complex-shaped fabrics and adapt to diversified production needs. In addition, the processing device integrates image processing and automatic control to reduce manual intervention, improve production efficiency, and reduce operating errors.

[0028] On the other hand, the curing head 2 includes an ultrasonic welder. Selecting an ultrasonic welder as the curing head 2 can achieve rapid curing, shorten the production cycle, and meet the requirements of mass production. In addition, there is no need to use adhesives, avoid high temperature damage to the fabric, maintain material properties, and meet environmental protection requirements.

[0029] On the other hand, the transfer device 3 includes a first guide rail 30 , a second guide rail 31 , and a third guide rail 32 .

[0030] The first guide rail 30 is arranged on both sides of the working surface 10. The second guide rail 31 is arranged horizontally above the working surface 10 and is slidably connected to the first guide rail 30 by means of a first mounting frame 33. The third guide rail 32 is arranged vertically above the working surface 10 and is slidably connected to the second guide rail 31 by means of a second mounting frame 34. The curing head 2 is slidably connected to the third guide rail 32 by means of a third mounting frame 35.

[0031] The transfer device 3 further includes a first driver 36, a second driver 37, and a third driver 38. The first driver 36 is connected to the first mounting frame 33, and is used to drive the first mounting frame 33 to slide along the first guide rail 30. The second driver 37 is connected to the second mounting frame 34, and is used to drive the second mounting frame 34 to slide along the second guide rail 31. The third driver 38 is connected to the third mounting frame 35, and is used to drive the third mounting frame 35 to slide along the third guide rail 32.

[0032] It should also be noted that for the specific types of the first driver 36, the second driver 37 and the third driver 38, a ball screw driver, a motor-driven belt driver and a motor-driven gear driver may be selected. Of course, other types of drivers may also be selected according to scene conditions.

[0033] On the other hand, Figure 5 At least two working areas Q are arranged on the working surface 10, and each working area Q is correspondingly provided with a camera 40 and a curing head 2. In this way, two samples can be placed at both ends of the working surface 10 at the same time, and the curing work of the fabric samples can be carried out at the same time to improve the work efficiency.

[0034] Specifically, a crossbeam 6 is disposed above the working surface 10 , and the camera 40 is disposed on the crossbeam 6 .

[0035] On the other hand, the working surface 10 is a light-transmitting surface, and a backlight 7 is further provided below the working surface 10. The backlight 7 provides brightness for the camera 40 above to enhance the image effect obtained.

[0036] In this regard, the working surface 10 in this embodiment is preferably a frosted glass surface. Since the frosted glass surface is diffusely reflective, the light transmitted is relatively soft, so that the image obtained by the camera 40 is clearer.

[0037] In this embodiment, the light source of the backlight 7 is preferably an LED lamp.

[0038] In addition, if Figure 4 and Figure 5The machine 1 is also provided with a light sensor 8, which is used to detect the ambient light brightness of the working surface 10, and the brightness of the backlight 7 changes dynamically with the detection value of the light sensor 8. Specifically, the light sensor 8 and the backlight 7 are both connected to the controller 5, and the controller 5 controls the power of the backlight 7 according to the detection value of the light sensor 8. Thus, the backlight 7 automatically adjusts the power of the backlight 7 based on the ambient light, achieving an energy-saving effect.

[0039] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
