The electrode layer attaching station 1 is used to automatically attach the first electrode layer 02 and the second electrode layer 03 to the two ends of the lower lining cloth 01; the lower adhesive film attaching station 2 is used to automatically attach the lower adhesive film 04 on the lower lining cloth 01 between the first electrode layer 02 and the second electrode layer 03; the silver paste coating station 3 ... The conductive areas of the first electrode layer 02 and the second electrode layer 03 are automatically coated with silver paste 05; the carbon film attaching station 4 is used to automatically attach the carbon film 06 between the conductive areas of the first electrode layer 02 and the second electrode layer 03; the upper adhesive film attaching station 5 is used to automatically attach the adhesive film 08 on the carbon film 06, the first electrode layer 02 and the second electrode layer 03; the upper lining cloth attaching station 6 is used to align and attach the upper lining cloth 07 to the lower lining cloth 01; the hot pressing molding station 7 is used to perform hot pressing molding on the semi-finished products after bonding; the detection station 8 is used to measure the resistance and spray the resistance code on the formed electric heating cloth, and sense the temperature of the red hot area; Among them, a lower lining cloth conveying assembly 9 is arranged across each workstation, which is used to convey the cut lower lining cloths 01 to each workstation through the base cloth; the lower lining cloth conveying assembly 9 includes a unwinding roller and a winding roller for driving the base cloth to be conveyed, and a plurality of feeding platforms 91 arranged in the processing area of ​​each workstation to support the base cloth.

[0025] In the present invention, a base cloth is wound on the unwinding shaft, and a plurality of cut lower lining cloths 01 are distributed on the base cloth. One end of the base cloth is pulled and wound by the winding shaft, so that the base cloth between the two spans across a plurality of material feeding platforms 91 of each station, and the electrode layer attaching station 1, the lower adhesive film attaching station 2, the silver paste coating station 3, the carbon film attaching station 4, the upper adhesive film attaching station 5, the upper lining cloth attaching station 6, the hot pressing molding station 7 and the inspection station 8 are independently arranged, and are accurately executed by the equipment during the operation, and each station is arranged in an assembly line, and the lower lining cloth 01 conveyed on the base cloth is processed one by one, and finally a finished electric heating cloth is obtained.

[0026] In the present invention, each workstation is automatically completed by the equipment, which reduces the errors caused by manual operation and effectively ensures the consistency of product quality. In addition, each workstation adopts an assembly line design and can complete specific processes in sequence, effectively avoiding process omissions or errors and reducing the scrap rate. The continuous transmission of the base cloth is achieved through the unwinding roller and the winding roller, and the preparation of the electric heating cloth can be completed uninterruptedly, which greatly improves production efficiency and meets large-scale production needs.

[0027] In the present invention, each workstation is independently arranged and can be adjusted or expanded according to production needs to adapt to the production of electric heating cloths with different specifications or functions; by adjusting the equipment parameters of each workstation, it is possible to quickly switch to produce different types of products, thereby improving production flexibility.

[0028] In the preferred embodiment of the present invention, a plurality of regularly distributed through hole groups 91a are provided at both end areas of the feeding platform 91, and a negative pressure area 91b is provided below the plurality of through hole groups 91a. Through the action of negative pressure, the plurality of through hole groups 91a can adsorb and position a section of base cloth conveyed to the work station.

[0029] Adsorption positioning can ensure that the base fabric remains flat and fixed in position during the conveying process, avoiding errors in subsequent processes caused by deviation or wrinkles of the base fabric. This positioning method ensures that the base fabric always maintains a consistent position and state during the processing of each station, thereby improving the stability of the production process and the consistency of product quality.

[0030] In the present invention, each workstation is independently arranged, and the upper surface of the feeding platform 91 on each workstation is located at the same horizontal plane. The distance between two adjacent workstations may cause the base cloth to lose its supporting force and sag slightly. In order to ensure that the base cloth smoothly enters the next workstation, arc-shaped guide plates 92 are provided at the ends of two adjacent feeding platforms 91.

[0031] The horizontally arranged feeding platform 91 can effectively prevent the base cloth from wrinkling or twisting due to height difference during the conveying process, ensuring that the base cloth always remains flat; and the arranged arc-shaped guide plate 92 can guide the sagging base cloth to smoothly enter the feeding platform 91, avoiding friction or jamming between the sagging base cloth and the edge of the platform. In addition, the arrangement of the arc-shaped guide plate 92 can disperse the tension of the base cloth, reduce the stretching or wear of the base cloth caused by sudden changes in direction, and extend the service life of the base cloth.

[0032] The feeding platform 91 of the present invention is arranged on one side of each workstation, and the other side is a material preparation area. The handling assembly located between the feeding platform 91 and the material preparation area transfers the parts to the lower lining cloth 01. However, during the conveying process, the base cloth is prone to deviation in the direction perpendicular to the conveying direction, resulting in the lower lining cloth 01 being unable to accurately reach the specified position, making it difficult to control the product quality. In order to solve this problem, both ends of the feeding platform 91 along the conveying direction are provided with a centering adjustment assembly 10, and the centering adjustment assembly 10 includes a bridge plate 101 arranged flush with the feeding platform 91, and a first limiter 102 and a second limiter 103 arranged on the bridge plate 101, and a driving assembly 104 for driving the first limiter 102 and the second limiter 103 to move closer to or away from each other along the direction perpendicular to the conveying direction.

[0033] By adjusting the distance between the first limit member 102 and the second limit member 103 through the driving component 104, it is possible to adapt to slight fluctuations of the base cloth during the transmission process. This dynamic adjustment mechanism can correct the position deviation of the base cloth in the direction perpendicular to the transmission direction in real time, ensuring the precise centering of the base cloth on the feeding platform 91; furthermore, the components can be accurately placed at the specified position of the lower lining cloth 01, avoiding installation errors caused by base cloth deviation, and significantly improving the consistency of product quality.

[0034] The equipment spacing between each workstation will cause the base fabric to lose support and sag slightly. When the base fabric is pulled and moved again, the equipment needs to pull and straighten the drooping base fabric first, and then the base fabric on the feeding platform 91 can be pulled and moved normally. This will cause a delay in the movement of the base fabric at each workstation, affecting the processing efficiency, and it is difficult to ensure the positioning accuracy of the lining fabric to be processed at each workstation. To solve this problem, as a preferred solution, an auxiliary traction assembly 11 is provided at the discharge end of the feeding platform 91, including an active roller 111, a driven roller 112, a rotating drive member 113 and a linear drive member 114; the linear drive member 114 drives the driven roller 112 to move along the vertical direction toward the active roller 111, so that the rubber wheels at both ends of the driven roller 112 and the active roller 111 clamp the edge of the base fabric, and the rotating drive member 113 drives the active roller 111 to rotate, so as to assist in traction of the base fabric.

[0035] Specifically, a support frame is provided at the discharge end of the feeding platform 91, an active roller 111 is provided in the support frame, and the upper surface of the active roller 111 is provided flush with the feeding platform 91, and a suspension is provided directly above the active roller 111, a driven roller 112 is provided in the suspension, a linear drive member 114 is provided above the support frame and the driving end is connected to the suspension, the driven roller 112 includes an intermediate roller and rubber rollers provided at both ends of the intermediate roller, the two ends of the intermediate roller are rotatably connected to the suspension through bearings, and the two rubber rollers are fixed to the intermediate roller, and when the current lower lining cloth 01 completes the processing of this station, the auxiliary traction assembly 11 is used to traction the base cloth, so that the next lower lining cloth 01 moves to the processing area of ​​this station to continue the processing operation. Preferably, the rotating drive member 113 adopts a motor, and the linear drive member 114 adopts a cylinder, but is not limited to the above drive forms.

[0036] In the present invention, the base fabric can be directly pulled by the clamping action of the active roller 111 and the driven roller 112, without the need for waiting time for transmission, which significantly improves the transmission efficiency of the base fabric between various workstations, and the cooperation of the linear drive member 114 and the rotary drive member 113 can accurately control the position and movement of the driven roller 112 and the active roller 111, thereby accurately controlling the moving position of the lower lining fabric 01, effectively ensuring the accuracy of the positioning of the lower lining fabric 01. In addition, the linear drive member 114 can adjust the gap between the driven roller 112 and the active roller 111, so that it can adapt to base fabrics of different thicknesses, thereby enhancing the versatility and flexibility of the equipment.

[0037] As a preferred embodiment of the above embodiment, a distance sensor is set between two adjacent feeding platforms 91, and the distance sensor is used to detect the sagging distance of the base fabric in real time, and the auxiliary traction component 11 can dynamically adjust the traction speed according to the sagging distance detected by the distance sensor at the feeding end of the feeding platform 91. In this way, the auxiliary traction component 11 can ensure that the base fabric always maintains appropriate tension during the transmission process, avoiding problems caused by sagging or excessive stretching. At the same time, adjusting the traction speed in real time according to the actual state of the base fabric can effectively avoid transmission delays or jamming, thereby significantly improving the overall production efficiency. In the specific adjustment process of the traction speed, the sagging distance detected by the sensor is input into the PID controller as a feedback signal. The PID controller calculates the adjustment amount of the traction speed according to the set target value, which is the ideal tension state of the base fabric, and sends the adjustment instruction to the driver of the traction motor, thereby achieving high-precision dynamic adjustment to ensure that the base fabric always maintains appropriate tension during the transmission process.

[0038] As a preferred solution, in the present invention, an auxiliary traction component 11 is provided at each workstation between the unwinding roller and the winding roller to realize segmented traction, so that the base cloth can be processed sequentially starting from the first workstation without pulling the base cloth directly to the winding roller, thereby reducing the waste of the base cloth end caused by the traction of the winding roller and ensuring the maximum utilization of the base cloth.

[0039] In the present invention, the electrode layer attaching station 1 is provided with a first attaching tool 1a and a second attaching tool 1b in sequence along the conveying direction of the base cloth; the first attaching tool 1a is used to attach the first electrode layer 02 to one end of the lower lining cloth 01; the second attaching tool 1b is used to attach the second electrode layer 03 to the other end of the lower lining cloth 01; wherein the first electrode layer 02 or the second electrode layer 03 adopts a single flexible electrode sheet or a combination of two flexible electrode sheets or a combination of multiple flexible electrode sheets.

[0040] By dividing the electrode layer attaching station 1 into a first attaching tool 1a and a second attaching tool 1b, the first electrode layer 02 and the second electrode layer 03 can be accurately attached respectively, ensuring that the position of the electrode layer on the lower lining cloth 01 is more accurate, thereby improving the consistency of product quality; and the electrode layer composed of multiple flexible electrode sheets is attached to the lower lining cloth 01 in an assembled form to meet the needs of different products.

[0041] In the preferred embodiment, a preheating and pressing plate 93 is provided on the feeding platform 91 of the upper lining cloth attaching station 6 for preheating the upper adhesive film 08 and the lower adhesive film 04 on the lower lining cloth 01 before the upper lining cloth 07 is attached.

[0042] Preheating can make the upper glue film 08 and the lower glue film 04 on the lower lining cloth 01 reach a more suitable temperature, so that when the upper lining cloth 07 is attached, the upper glue film 08 can better adhere to the upper lining cloth 07, reduce the generation of bubbles and wrinkles, and improve the flatness and firmness of the attachment; in addition, preheating can make the upper glue film 08 and the lower glue film 04 reach the partial curing temperature in advance, reduce the heating time in the subsequent hot pressing process, and thus improve production efficiency.

[0043] In a preferred embodiment of the present invention, a coding mechanism 12 is provided before the electrode layer attachment station 1, which is used to perform coding positioning on a plurality of lower lining cloths 01 on the base cloth; a barcode scanner is provided at each station, and the position of the lower lining cloth 01 to be processed is determined by scanning the barcode. The coding mechanism 12 pre-prints the barcode before processing the lower lining cloth 01 on the base cloth, and the barcode scanner quickly reads the barcode information at each station, thereby achieving accurate positioning and rapid identification of the lower lining cloth 01. This automated information processing method significantly reduces manual operation time and improves production efficiency. By recording the position and processing status of each lower lining cloth 01 with a barcode scanner, a complete product production history can be constructed, which is convenient for tracing back quality problems in the later stage. This data recording method provides strong support for transparency and quality control of the production process.

[0044] The forming device of the present invention further includes a material receiving station 13, which includes a stripping plate arranged at the material discharging end of the detection station 8, and a material receiving box for conveying and storing the finished electrically heated fabric after being stripped from the base fabric.
