[0024] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0025] The present application provides a device for detecting glue uniformity of cigarette paper, which moves a spectral confocal sensor on a gluing area on the cigarette paper to detect the glue thickness at each point in the gluing area, and determines the glue uniformity by statistics of thickness data, thereby avoiding the problems of low accuracy and low efficiency caused by relying on manual observation and hand feeling judgment.

[0026] like Figure 1 As shown, the cigarette paper glue uniformity detection device provided by the present application comprises a controller, a cigarette paper positioning component 10, a spectral confocal sensor 20 movably arranged above the cigarette paper positioning component, a data processor and a display 30, and the detection range of the spectral confocal sensor 20 covers the glued area on the cigarette paper positioned on the cigarette paper positioning component 10. The controller is respectively connected to the actuator signals of the cigarette paper positioning component 10, the spectral confocal sensor 20 and its movable driving component, the spectral confocal sensor 20 is connected to the data processor by signal, and the data processor is connected to the display 30 by signal.

[0027] The spectral confocal sensor 20 calculates the thickness information of the glue by obtaining the reflected light information of two opposite end surfaces in the gluing area of ​​the cigarette paper, and has the characteristics of non-contact, high precision, high speed, and suitable for transparent object detection.

[0028] When in use, the cigarette paper to be tested is positioned on the cigarette paper positioning component 10, and then the controller controls the moving driving component of the spectral confocal sensor 20 to drive the spectral confocal sensor 20 to move, so that the spectral confocal sensor 20 measures the glue thickness at each point on the cigarette paper, and transmits the thickness data to the data processor. The data processor determines the uniformity of the glue based on the glue distribution information reflected by the thickness data, and displays the glue uniformity test result on the display.

[0029] It should be noted that the above data processing method of the data processor is a commonly used uniformity analysis method, and this application does not make any improvements to the data processing part.

[0030] As an embodiment, the model of the data processor is an STM32 series chip (eg, STM32F107).

Before the detection, the vacuum generator is turned on by the controller so that the cigarette paper is evenly adsorbed on the top surface of the cigarette paper positioning component 10, so as to avoid inaccurate detection caused by uneven cigarette paper.

During positioning, two adjacent sides of the cigarette paper are respectively fitted with the two scales, so that the positioning of the cigarette paper remains consistent, and the moving range of the spectral confocal sensor 20 is deterministic, reducing the difficulty of operation.

After the Y-axis motor 60 is started, the sensor mounting seat 40 is driven to move along the Y-axis through the first screw rod 70, thereby driving the spectral confocal sensor 20 to move along the Y-axis.

[0035] Preferably, two first guide rods 51 are arranged symmetrically and parallel to the first screw rod 70 on the Y-axis support frame 50. The first guide rods 51 make the movement of the sensor mounting seat 40 on the Y-axis more stable.

A second screw thread connected to the second screw rod is provided on the first side surface of the Z-axis slider 90, and the spectral confocal sensor 20 is fixed on the second side surface (opposite to the first side surface) of the Z-axis slider 90.

[0037] Before detection, the controller controls the Z-axis motor 80 to rotate, thereby driving the Z-axis slider 90 to drive the spectral confocal sensor 20 to move along the Z-axis (i.e., move up and down), so that the spectral confocal sensor 20 moves to a height that matches the standard glue thickness of the cigarette paper, thereby improving the accuracy of detection.

[0038] On the basis of the above, preferably, an X-axis driving component is slidably provided below the cigarette paper positioning component 10, and the actuator of the X-axis driving component is connected to the controller signal.

[0039] Preferably, the glue uniformity detection device further comprises a base 100, the X-axis driving component is arranged on the top surface of the base 100, and the Y-axis support frame 50 is fixed above the side of the base 100 through a vertical bracket. The data processor is arranged in the inner cavity of the base 100.

[0040] As an embodiment, the display 30 is rotatably disposed on the outside of the base 100 through a bracket.
