Abstract
Description
Technical Field
[0001] The utility model relates to the field of film bubble thickness gauges, in particular to an annular film bubble thickness gauge. Background Art
[0002] A film bubble thickness gauge is a device used to measure the thickness of a film. It usually consists of a sensor, a measuring circuit, and a display. The sensor is responsible for contact or non-contact measurement of the film and converts the measurement result into an electrical signal. The measuring circuit processes the electrical signal to obtain the thickness value of the film. The display part displays the thickness value in the form of numbers or graphs.
[0003] However, when using a traditional film bubble thickness gauge, it is difficult to control the distance between the thickness measuring device and the film bubble in a timely manner, the dynamic detection effect is poor, and the thickness of the film bubble cannot be measured continuously and accurately. For example: when using the thickness measuring device to actually measure the thickness, the size of the film bubble to be measured varies, and the thickness measuring device needs to be close to the film bubble to measure the thickness stably and accurately. As the size of the film bubble changes, it is difficult to maintain the dynamic proximity between the thickness measuring device and the film bubble. Utility Model Content
[0004] The utility model discloses an annular film bubble thickness gauge, which aims to solve the technical problems that when a traditional film bubble thickness gauge is used, the distance between a thickness measuring device and the film bubble is difficult to control in time, the dynamic detection effect is poor, and the thickness of the film bubble cannot be measured continuously and accurately.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A ring-shaped film bubble thickness gauge comprises a ring frame and a mounting seat arranged on the top of the ring frame, and also comprises: a linkage mechanism: the linkage mechanism is arranged at the connection between the mounting seat and the ring frame; a proximity thickness measuring mechanism: the proximity thickness measuring mechanism comprises a first rotating joint arranged on the top outer wall of the mounting seat, a swing arm is connected to the first rotating joint, a second rotating joint is arranged on the top outer wall of the swing arm away from the first rotating joint, a capacitive thickness measuring component is installed on the second rotating joint, a distance sensor and a capacitive probe are respectively arranged on the capacitive thickness measuring component, and a mechanical arm control component is arranged on one side of the bottom outer wall of the mounting seat.
[0007] In this solution, by setting up a proximity thickness measurement mechanism, the swing arm and the capacitive thickness measurement component can be dynamically controlled to approach membrane bubbles of different sizes. The rotation of the first rotary joint can make the swing arm approach the membrane bubble to be measured, and the rotation of the second rotary joint can adjust the capacitive probe on the capacitive thickness measurement component to always be facing close to the membrane bubble to be measured. This not only maintains the stability of the thickness measurement between membrane bubbles of different sizes, but also ensures the accuracy of the thickness measurement.
[0008] In a preferred solution, the linkage mechanism includes mounting column feet arranged at the four corners of the outer wall at the bottom of the mounting seat, and two groups of mounting column feet located on both sides of the bottom of the mounting seat are provided with inclined grooves at relative positions, a fixed inclined plate is provided on one side of the inclined groove, and rollers are connected to the opposite sides of the fixed inclined plate and the inclined groove through bearings, a gear ring is fixedly connected to the circumferential outer wall of the ring frame near the top, and an outer convex inclined surface is provided on the circumferential outer wall of the ring frame near the bottom, and the outer convex inclined surface is matched with the rollers located on the mounting column feet, and a motor is provided on one side of the outer wall at the top of the mounting seat, and one end of the motor output shaft is connected to a driving gear, and the driving gear is matched with the gear ring.
[0009] The rotation of the active gear driven by the motor can cooperate with the gear ring fixedly installed on the ring frame, so as to utilize the reverse meshing force to drive the mounting seat to move and adjust along the ring frame. During the adjustment process, the roller arranged on the mounting column foot can not only cooperate with the rolling, but also form a clamping cooperation with the arranged convex inclined surface, so as to drive the mounting seat to stably slide and connect to the ring frame to avoid falling off, thereby ensuring the stability of the thickness measurement process.
[0010] As can be seen from the above, an annular film bubble thickness gauge includes a ring frame and a mounting seat arranged on the top of the ring frame, and also includes: a linkage mechanism: the linkage mechanism is arranged at the connection between the mounting seat and the ring frame; a proximity thickness measuring mechanism: the proximity thickness measuring mechanism includes a first rotating joint arranged on the top outer wall of the mounting seat, a swing arm is connected to the first rotating joint, a second rotating joint is arranged on the top outer wall of the swing arm away from the first rotating joint, a capacitive thickness measuring component is installed on the second rotating joint, a distance sensor and a capacitive probe are respectively arranged on the capacitive thickness measuring component, and a mechanical arm control component is arranged on one side of the bottom outer wall of the mounting seat.

[0019] Among them, the length of the swing arm 7 is greater than the distance between the mounting seat 3 and the membrane bubble; in this way, the adjustment of the swing arm 7 can be maintained to adapt to a wider range of membrane bubble positions, and the thickness measurement process is more stable.
[0020] Among them, the robot arm control component is used to control the rotation of the first rotary joint 13 and the second rotary joint 14, and the robot arm control component is electrically connected to the distance sensor; through the control of the robot arm control component, the deflection of the swing arm 7 and the deflection of the capacitive thickness measuring component 8 can be closely coordinated to ensure the accuracy of the thickness measurement process.
[0021] During actual use, through the proximity thickness measuring mechanism, the swing arm 7 and the capacitive thickness measuring component 8 can be dynamically controlled to approach membrane bubbles of different sizes. The rotation of the first rotary joint 13 can make the swing arm 7 approach the membrane bubble to be measured, and the rotation of the second rotary joint 14 can adjust the capacitive probe on the capacitive thickness measuring component 8 to always be facing close to the membrane bubble to be measured.
[0022] Reference Figure 2 and Figure 3 In a preferred embodiment, the linkage mechanism includes mounting column feet 4 arranged at the four corners of the outer wall at the bottom of the mounting seat 3, and two groups of mounting column feet 4 located on both sides of the bottom of the mounting seat 3 are provided with inclined grooves at relative positions, and a fixed inclined plate 11 is provided on one side of the inclined groove, and a roller 12 is connected to the opposite side of the fixed inclined plate 11 and the inclined groove through a bearing.

[0024] It should be noted that during the adjustment process, the roller 12 provided on the mounting column foot 4 can not only cooperate in rolling, but also form a clamping fit with the provided convex inclined surface 9, thereby driving the mounting seat 3 to slide stably and connect to the ring frame 1 to avoid falling off.
[0025] Reference Figure 1 In a preferred embodiment, two groups of supporting legs 2 are symmetrically provided on the bottom outer wall of the ring frame 1, and the number of supporting legs 2 in each group is two.
