Description

Technical Field

[0001] The utility model relates to the technical field of film thickness gauges, in particular to an automatic film thickness measuring instrument. Background Art

[0002] The thickness of a film often affects various properties of the film, specifically optical properties, electrical properties, mechanical properties, thermal properties, etc. Therefore, it is necessary to measure the thickness of the film to ensure that the film used can maintain high performance. However, when measuring the thickness of a film, the film is generally transported in the direction of thickness measurement by rolling, and rolling will generate friction, causing the film to generate static electricity. Static electricity will cause uneven charge distribution on the surface of the film, ultimately affecting the thickness measurement results.

[0003] In the prior art, a utility model patent (CN210513084U) discloses a convenient-to-use film thickness gauge, which relates to the technical field of thickness gauges, including a workbench, a measuring rod arranged on the workbench, a rotating rod rotatably arranged on the workbench, a clamping mechanism arranged on the workbench, and the clamping mechanism includes a fixed seat arranged on the workbench, a clamping disc slidably arranged on the fixed seat, and a driving device arranged on the fixed seat. The casing thickness gauge cannot remove static electricity from the film.

[0004] Based on this, the technical problem to be solved in this case is: how to provide an automatic thickness measuring instrument for removing static electricity. Utility Model Content

[0008] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0009] The utility model can prevent the measurement accuracy from decreasing due to static electricity generated when the driving mechanism drives the film to move when measuring the film thickness by using the static electricity removing device.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Example 1

[0015] See also Figures 1 to 3 A film automatic thickness measuring instrument comprises a frame 1 and a thickness measuring device 2. The frame 1 is provided with a workbench 11, the thickness measuring device 2 is connected to the workbench 11, the thickness measuring device 2 is provided with a driving mechanism 3 for driving the film to move along the length direction of the workbench 11, the frame 1 is also provided with a static electricity removal device 4, and the static electricity removal device 4 is located on one side of the film input end of the workbench 11.

[0016] In actual use, the staff places the film on the workbench 11 and drives the film from one side of the workbench 11 to the other side through the driving mechanism 3. Specifically, the starting point of the moving direction is the film input end, and the end point of the moving direction is the film input end. The film will pass through one side of the static electricity removal device 4 at the film input end. At this time, the static electricity removal device 4 will remove the static electricity of the film on the film input end until the static electricity is removed and then pass under the thickness measuring device 2 to measure the thickness. This can prevent the existence of static electricity on the film during thickness measurement, which will not only affect the measurement accuracy of the thickness measuring device 2, but also cause the aggregation or adhesion of tiny particles on the surface of the film, that is, it will affect the accuracy of the film thickness measurement. Therefore, the static electricity can be removed by the static electricity removal device 4 before the film thickness is measured, so as to improve the accuracy of the film thickness measurement.

[0017] Furthermore, the static electricity removal device 4 includes a fixed bracket 41 and an ion fan 42 connected to the fixed bracket 41 . The fixed bracket 41 is located at one side of the film input end of the workbench 11 .

[0018] In the above design, the fixed bracket 41 can fix the position of the ion fan 42 and provide support, so that the ion fan 42 remains stable during the process of removing static electricity, and can continuously remove static electricity on the film, thereby improving measurement accuracy.

[0019] Preferably, a rotating member 43 is disposed on the fixed bracket 41 , and the rotating member 43 is connected to the ion fan 42 . The angle of the ion fan 42 can be adjusted by the rotating member 43 .

[0020] Through the above design, the ion fan 42 can rotate to adjust the angle, and then the wind direction of the ion fan 42 can be adjusted, thereby improving the efficiency and effect of static electricity removal.

[0021] More preferably, the driving mechanism 3 includes a rotating roller 31 located above the workbench 11, the rotating roller 31 is rotatably connected to the thickness measuring device 2, and the thickness measuring device 2 is provided with a rotating driving module 311 for driving the rotating roller 31 to rotate, and the rotating roller 31 is used to press the film onto the workbench 11 and drive the film to move along the length direction of the workbench 11.

[0022] In this embodiment, the film can be driven to move from the film input end to the film output end by rotating the roller 31, and the film can be pressed against the workbench 11. In this way, the film can be moved on the workbench 11. On the one hand, it can ensure that the film can pass under the thickness measuring device 2, that is, to ensure the thickness measurement of the film. On the other hand, it can ensure the moving direction of the film, and it is not easy to deviate, thereby ensuring the thickness measurement effect.

[0023] More preferably, it further includes an auxiliary roller 32, the rotating roller 31 is located on one side of the film output end of the workbench 11, and the top of the rotating roller 31 and the top of the workbench 11 are located on the same horizontal line, the auxiliary roller 32 is located above the rotating roller 31, and a first gap 33 is provided between the auxiliary roller 32 and the rotating roller 31, and the first gap 33 is used for allowing the film to pass through, and the thickness measuring device 2 is also provided with a lifting unit 321 for driving the auxiliary roller 32 to move upward or downward relative to the rotating roller 31, the rotating roller 31 is used to drive the film to move along the length direction of the workbench 11, and the auxiliary roller 32 is used to press the film against the rotating roller 31.

[0024] In this embodiment, the film can be moved along the length direction of the workbench 11 by the auxiliary roller 32 and the rotating roller 31. Specifically, the film passes through the first gap 33 to ensure that the film does not deviate, thereby ensuring that the measured thickness of the film is along the same direction of the film. In this way, it can be ensured that the sampling points for measuring the thickness of the film are in the same direction of the film, which is more convenient for comparison, so as to detect the uniformity of the film thickness. On the other hand, the auxiliary roller 32 can be raised and lowered, which can not only adjust the size of the first gap 33, but also the auxiliary roller 32 can go up after the film thickness measurement is completed, which makes it convenient to place the film in the first gap 33 when performing the next thickness measurement. At this time, the auxiliary roller 32 goes down and cooperates with the rotating roller 31 to drive the film to move along the length direction of the workbench 11, which is convenient for the normal progress of subsequent thickness measurement.

[0025] Furthermore, it also includes a feeding unit 5, which includes a guide wheel bracket 51 and a film feeding guide wheel 52 connected to the guide wheel bracket 51. The guide wheel bracket 51 is located on one side of the fixed bracket 41 and is connected to the film input end of the workbench 11.

[0026] Through the above design, the film can be guided by the feeding unit 5 so that the film can move horizontally along the length direction of the workbench 11, and the film feed guide wheel 52 can reduce friction to prevent the shape of the film from being deformed by friction and causing thickness measurement distortion.

[0027] Furthermore, a limiting mechanism 6 is provided on the workbench 11, and the limiting mechanism 6 includes a horizontally arranged support rod 61 and two vertically arranged limiting rods 62. The support rod 61 is connected to one end of the workbench 11 close to the guide wheel bracket 51, and the two limiting rods 62 are both slidably connected to the support rod 61, and a second gap is provided between the two limiting rods 62 for the film to pass through.

[0028] In this embodiment, the limiting mechanism 6 can further prevent the film from detaching from the workbench 11. Specifically, the limiting rod 62 can limit the film from passing through the second gap between the limiting rods 62, thereby preventing the film from detaching from the workbench 11, thereby ensuring that the thickness measurement of the film can be carried out normally. Specifically, the size of the second gap can be adjusted by moving the two limiting rods 62.

[0029] Preferably, the thickness measuring device 2 includes a support base 21 connected to the workbench 11, and a detection component 22 connected to the support base 21, the detection component 22 is provided with a liftable probe 221, the probe 221 is located above the workbench 11, and the driving mechanism 3 is connected to the support base 21.

[0030] In the above design, by raising and lowering the probe 221, the thickness can be measured downward after the film moves a certain distance. In particular, the staff can set the distance so that the staff can set the distance according to the specific situation and adjust it according to the actual situation to improve controllability.

[0031] More preferably, the detection component 22 includes a pneumatic telescopic rod 222 connected to the support seat 21, a sensor connected to the pneumatic telescopic rod 222, and the measuring head 221 is connected to the power output end of the pneumatic telescopic rod 222. The measuring head 221 can move up or down relative to the workbench 11 under the drive of the pneumatic telescopic rod 222.

[0032] Through the above design, the probe 221 can move up or down relative to the workbench 11 through the pneumatic telescopic rod 222, and the probe 221 will only move down after the sensor detects that there is a film under the probe 221, so as to measure the thickness of the film. This can prevent the probe 221 from continuing to move when the end of the film is no longer under the probe 221, thereby obtaining an erroneous data, resulting in data distortion. It should be noted that the sensor is not shown in the figure.

[0033] More preferably, a plurality of foot pads 12 are provided at the bottom of the rack 1 , and a plurality of indicator lights 13 are provided on the rack 1 .

[0034] In this embodiment, the foot pad 12 can improve the overall stability, and the indicator light 13 can allow the staff to visually observe which process the thickness measuring instrument is working at, so as to know when the thickness measurement work is completed.
