[0002] In the production process of the assembled inflatable structure, the TPU cloth needs to be heat sealed into a specific cylindrical shape to make inflatable modules. At present, the cloth heat sealing work in this field mainly relies on manual operation. Manual heat sealing not only has low efficiency and cannot meet the demand of batch production, but also has the problem of poor heat sealing precision. When manually operating, it is difficult to ensure the uniformity of the cloth gap, which may cause wrinkles and cloth strip deviation in the heat sealed cloth, resulting in uneven product quality and high scrap rate.

Traditional cloth heat sealing equipment is mostly integrated and fixed structure, which cannot be adjusted according to the characteristics of TPU cloth, and is inconvenient to disassemble and assemble. When a local fault occurs, the whole machine needs to be stopped for maintenance, which further affects the production efficiency. In addition, when operating the heat sealing equipment manually, the operator directly contacts the heat source, which may cause burns and other safety risks. Therefore, there is an urgent need for an automatic, high-precision and easy-to-maintain TPU cloth heat sealing device to solve the defects of the prior art. SUMMARY

[0024] like Figs. 1-3 As shown, this embodiment of the invention discloses an automatic heat-sealing fabric device based on visual recognition, comprising: The main body of the device integrates a pressing structure, a guiding structure, a heat source structure, and a visual recognition component, which are used to thermally shape the flat TPU fabric 2 into a cylindrical shape. The pressing structure is installed at the feeding end of the main body of the device, including a drive motor and two stainless steel wheels arranged opposite each other. The drive motor is connected to the stainless steel wheels and is used to drive the stainless steel wheels to rotate, so as to realize the pressing and uniform conveying of the fabric. The guide structure, located at the discharge end of the pressing structure, includes two stepper motors 5 and two correspondingly arranged rubber omnidirectional wheels. The stepper motors are connected to the rubber omnidirectional wheels and are used to adjust the size of the gap in the fabric. The heat source structure includes a hot air gun 1 and a heat source sensor. The hot air gun is used to provide the heat source required for heat sealing of the fabric, and the heat source sensor is used to monitor the temperature of the heat-sealed part. The visual recognition component is electrically connected to the stepper motor of the guide structure. It is used to collect image information of the fabric position and gap, and control the stepper motor to adjust the position of the rubber omnidirectional wheel 3.

[0025] Furthermore, the visual recognition component includes an industrial camera 4 and an image processor. The industrial camera is positioned facing the heat-sealed seam area of ​​the fabric. The image processor is electrically connected to the industrial camera and the stepper motor, respectively, and is used to process image information and output adjustment signals.

[0026] Further, the air outlet of the hot air gun is directed towards the heat sealing position of the fabric, and the distance from the surface of the fabric is 5-10 cm.

[0027] In the specific use process, the TPU fabric to be heat sealed is sent in from the left feeding end, is adhered and guided by the feeding guide roller formed by the stainless steel wheel of the pressing structure, and is stably sent between the two groups of rubber omnidirectional wheels of the guide structure. At this time, the gap of the fabric to be heat sealed is in a preliminary alignment state. In the embodiment, each group of rubber omnidirectional wheels is one or more.

[0028] The industrial camera of the visual recognition assembly is started, and the gap area of the fabric to be heat sealed is photographed in real time. The image is transmitted to the image processor, the processor analyzes the width and uniformity of the gap, and if the gap does not meet the heat sealing requirements, an adjustment signal is output to the two groups of stepping motors of the guide structure to control the rubber omnidirectional wheels on both sides to translate inward / outward synchronously, so as to adjust the fabric gap to a uniform preset range.

[0029] The fabric with the adjusted gap continues to be conveyed forward, and when it reaches the heat source structure area, the hot air gun is started and blows hot air at a preset temperature to heat seal the fabric gap. At the same time, the heat source sensor monitors the temperature of the heat sealing position in real time to ensure that the heat sealing temperature is within the preset range.

[0030] The fabric that has completed heat sealing enters between the two stainless steel wheels of the pressing structure, the driving motor drives the stainless steel wheels to rotate reversely synchronously, and at the same time, the fabric is conveyed, so as to compact the heat sealing position and enhance the heat sealing firmness of the TPU fabric. Finally, the fabric heat sealed into a cylindrical shape is sent out from the right finished product output end, and the automatic heat sealing process is completed.

[0031] If batch production is required, the TPU fabric can be continuously sent to the feeding end, and the device will repeat the above process to realize continuous automatic heat sealing.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
