[0002] In the coating process of double-sided tape, the thickness is measured as a whole after coating and drying, which cannot effectively measure the thickness of individual parts. This affects the stability of the double-sided tape's subsequent performance.

[0005] A double-sided coating online thickness detection device, characterized in that it includes first, second, and third spectral sensor probe groups and first and second temperature control chambers. The first and second temperature control chambers are respectively located after the first and second adhesive layer drying ovens. The first spectral sensor probe group is positioned after the first temperature control chamber, perpendicular to the first adhesive layer. The second and third spectral sensor probe groups are positioned after the second adhesive layer temperature control chamber, perpendicular to the second and first adhesive layers of the double-sided tape, respectively. The first and third spectral sensor probe groups are connected via a controller to an electric heater inside the first adhesive layer drying oven and a support cylinder supporting the first adhesive layer coating roller. The second spectral sensor probe group is connected via a controller to an electric heater inside the second adhesive layer drying oven and a support cylinder supporting the second adhesive layer coating roller. The first adhesive layer drying oven has an electric cylinder for supporting the coating roller; the electric heater in the first adhesive layer drying oven is located on one side corresponding to the first adhesive layer, and the electric heater in the second adhesive layer drying oven is located on one side corresponding to the first and second adhesive layers respectively, with the temperature of the electric heater on the side corresponding to the second adhesive layer being higher than the temperature of the electric heater on the side corresponding to the first adhesive layer; the first, second, and third spectral sensor probe groups each include three probes (left, center, and right) perpendicular to the coating feed direction; the electric heaters in the first and second adhesive layer drying ovens each include multiple sets of heater groups arranged along the coating feed direction, with each set of heaters having three sections (left, center, and right) perpendicular to the coating feed direction; the first and second temperature control boxes are either air-cooled or water-cooled.

[0006] The third spectral sensor probe group is connected to the support electric cylinder of the reversing roller between the first adhesive layer oven and the second adhesive layer coating roller via a controller.

[0007] The sampling frequency of the probes in the first, second, and third spectral sensor probe groups is 1000Hz.

[0008] The first and third spectral sensor probe groups are connected to the lifting cylinder of the scraper support frame corresponding to the first adhesive layer coating roller via the controller, and the second spectral sensor probe group is connected to the lifting cylinder of the scraper support frame corresponding to the second adhesive layer coating roller via the controller.

[0012] 1. Thickness is detected by sampling with a spectral sensor probe group, allowing for online detection without downtime and providing high detection accuracy.

[0013] 2. After the first adhesive layer is coated and pre-dried in the first adhesive layer oven, the pre-dried thickness of the first adhesive layer is detected by the first spectral sensor probe group. After the second adhesive layer is coated and pre-dried in the second adhesive layer oven, the final dried thickness of the first and second adhesive layers is detected by the second and third spectral sensor probe groups. The detection data is used to adjust the pre-drying temperature of the first adhesive layer, adjust the adhesion between the first adhesive layer coating roller and the base fabric by adjusting the support electric cylinder, adjust the gap between the scraper and the coating roller on the scraper support frame by adjusting the scraper electric cylinder, adjust the tension of the base fabric conveyed by the reversing roller support frame by adjusting the support electric cylinder, adjust the temperature of the electric heaters in the first and second adhesive layer ovens, and adjust the temperature control temperature of the first and second temperature control boxes to meet the adjustment requirements of the designed dry adhesive thickness of the first and second adhesive layers, while having a good and stable online detection function.

[0014] 3. The spectral sensor probe group uses three probes (left, center, and right), and the heater group used with the electric heater uses three sections (left, center, and right). This allows for fine-tuning of the drying performance in the width direction of the coated base fabric. Furthermore, the uniformity of the coating thickness in the width direction can be adjusted by adjusting the lifting cylinder on either side of the coating roller or the doctor blade support frame, thereby further ensuring online control of the coating thickness.
