Description

Technical Field

[0001] The present invention relates to the technical field of measuring the thickness of the body of a packaging bottle, and specifically to a device for measuring the thickness of the body of a packaging bottle based on laser detection. Background Art

[0002] During the process of measuring the thickness of the body of a packaging bottle, a spectral confocal sensor is used. This device is a high-precision non-contact measurement technology, suitable for thickness, distance, and high-precision position measurement in various industrial applications. It can measure different materials, including transparent and non-transparent materials, with high resolution and accuracy without the need to contact the object to be measured.

[0003] In order to avoid the deformation of the bottle body due to force during the detection process and the influence of the bottom supporting tool wrapping the outer wall of the bottle body on the laser scattering amplitude, resulting in distorted measurement data, some existing devices for measuring the thickness of the body of a packaging bottle by laser detection generally place the bottle body horizontally above the device base, so that the bottle body rests statically on the top of the base by its own gravity. However, due to the cylindrical shape of the bottle body and the relatively smooth outer wall, external vibrations and other factors can easily cause it to shake or even roll, which is rather inconvenient.

[0018] 1. When the present invention is in use, by setting a rotating column, a plurality of threads are symmetrically arranged inside the rotating column. A sliding seat is fixedly connected to the bottom of the rotating column, a transfer seat is fixedly connected to one side of the sliding seat, a displacement screw is rotatably connected to the inside of the transfer seat, a support plate is slidably connected to the inside of the sliding seat, a support frame is fixedly connected to the top of one side of the support plate, a transfer sleeve column is rotatably connected to the outside of the top of the support frame, and a bearing plate is fixedly connected to the top of the transfer sleeve column. According to the length of the bottle body to be measured, the second motor is turned on to drive the second screw to rotate, and in cooperation with the sliding of the moving plate on the outside of the second screw, the moving plate is translated to the required horizontal position. The fixing screw is rotated counterclockwise and loosened, and the sliding arm is lifted and lowered to the required height in cooperation with the U-shaped limiting hole.

According to the required height, the lifting screw is rotated inside the slider, and the spectral confocal sensor is moved to the required height by the sliding of the lifting block on the outside of the second sliding rod. The first motor is turned on to drive the first screw to rotate, so that the slider is translated in the direction of the top of the bottle body. Through the laser irradiation of the spectral confocal sensor, the thickness of the bottle body is measured. It can effectively ensure the stability of the position of the bottle body during the laser thickness detection process, reduce the influence of the cylindrical shape and relatively smooth outer wall of the bottle body, and prevent the situation of shaking or even rolling caused by external vibrations and other factors.

[0019] 2. By setting the limiting side pieces, with the moving plate fixedly connected to one side of each limiting side piece and the sliding arm slidably connected to the other side of each limiting side piece, the present invention can effectively ensure the stability of the position of the sliding arm during the lifting and use process and reduce its swinging amplitude.
