Detailed Description
Referring to fig. 1-4, a thickness measuring device capable of preventing a capacitor film from being damaged due to tension according to an embodiment of the invention comprises a frame 1, a film material roller 2, a winding roller 3, a thickness measuring guide roller 4 and a thickness measuring probe 5. The film material roller 2, the thickness measuring guide roller 4 and the winding roller 3 are arranged on the frame 1 through the shaft seat 101, and the film material roller 2, the thickness measuring guide roller 4 and the winding roller 3 are parallel to each other. The film material roller 2 is sleeved with a film 6 coiled material, and one end of the film 6 coiled material bypasses the thickness measuring guide roller 4 and is connected with the winding roller 3. The thickness measuring probe 5 is fixedly arranged on the frame 1, the thickness measuring probe 5 is used for measuring the thickness of the film 6, the thickness measuring probe 5 preferably adopts a reflective laser thickness measuring sensor, the thickness measuring probe 5 is arranged right above the thickness measuring guide roller 4, and the thickness measuring probes 5 are axially distributed at equal intervals along the thickness measuring guide roller 4.
During operation, the film 6 bypasses the thickness measuring guide roller 4 and is attached to the surface of the thickness measuring guide roller 4, the nearest distance between the film 6 and the thickness measuring guide roller 4 can be measured by the thickness measuring probe 5 in advance, and the nearest distance is taken as a thickness measuring zero point, so that when the film 6 is measured, the thickness measuring probe 5 emits laser to irradiate the surface of the film 6, and then the reflected light is received by the CCD and then is calculated by the processor to obtain a measurement result, so that the thickness of the film 6 can be measured.
In this embodiment, one end of the film material roller 2 is connected with a first power roller 7, one end of the winding roller 3 is connected with a second power roller 8, one end of the thickness measuring guide roller 4 is connected with a guide roller 9, the diameters of the thickness measuring guide roller 4 and the guide roller 9 are the same, the first power roller 7 and the second power roller 8 are in coiled material transmission connection through a transmission belt 10, the transmission belt 10 coiled material bypasses the guide roller 9, the coiled material of the transmission belt 10 is different from the coiled material of the film 6, and the coiled material of the transmission belt 10 is preferably made of rubber. One end of the first power roller 7 is connected with a first driving motor 11 through a clutch, one end of the second power roller 8 is connected with a second driving motor 12 through a clutch, and both the first driving motor 11 and the second driving motor 12 are arranged on the frame 1.
When the film winding device works, the first driving motor 11 and the second driving motor 12 can be used for driving the driving belt 10 to wind, and when the driving belt 10 winds, the first power roller 7 and the second power roller 8 can be driven to synchronously rotate, and then the film material roller 2 and the winding roller 3 can be driven to synchronously rotate to convey the film 6 coiled material. It should be noted that, when the belt 10 is wound, the first driving motor 11 and the second driving motor 12 cannot be simultaneously in the working state, that is, when one of them is working, the other is not working. For example, when the first drive motor 11 is required as the power source device, the output shaft of the first drive motor 11 may be connected to the first power roller 7 through a clutch to drive, and the output shaft of the second drive motor 12 may be disconnected from the second power roller 8 through a clutch, or vice versa. Therefore, the coiled material of the driving belt 10 can be wound back and forth between the first power roller 7 and the second power roller 8 through the first driving motor 11 and the second driving motor 12, so that after the thickness measuring work of the coiled material of the film 6 is completed, the driving belt 10 can be wound back on the first power roller 7 before the next thickness measuring work, and the thickness measuring work of the subsequent film 6 can be more conveniently carried out.
According to the thickness measuring device of the present embodiment, when the film 6 is to be measured, the film 6 coil can be first installed on the device, so that the diameter and the winding number of the film 6 coil on the film material roller 2 are the same as those of the driving belt 10 coil on the first power roller 7, and the diameter and the winding number of the film 6 coil on the winding roller 3 are the same as those of the driving belt 10 coil on the second power roller 8, so that when the first driving motor 11 or the second driving motor 12 is started to work, the winding speed of the film 6 coil is kept the same as that of the driving belt 10 coil. When the film 6 coiled material is installed, the film 6 is only straightened between the film material roller 2 and the winding roller but is not tensioned, and the driving belt 10 coiled material plays a driving role, so that the driving belt 10 can bear driving tension when being wound, the film 6 coiled material is wound at the same winding speed and can not bear the driving tension, thereby preventing the film 6 from deforming and improving the thickness measuring precision of the film 6.
Referring to fig. 3, in a further embodiment, a compacting spindle head 201 is screwed to an end of the film roll 2 away from the first power roll 7, and the compacting spindle head 201 is used for compacting and fixing the film 6 coiled material on the film roll 2. When the film 6 coiled material is installed, the compression shaft head 201 can be detached firstly, and after the film 6 coiled material is installed, the compression shaft head 201 can be screwed on the film material roller 2, so that the film 6 coiled material is compressed and fixed, and the film 6 coiled material can be conveniently installed and taken down through the compression shaft head 201.
To further facilitate the mounting and dismounting of the film 6 coil, the pinch roller head 201 is rotatably mounted on the slide shaft seat 102, the slide shaft seat 102 is mounted on the frame 1 by means of the slide rail 103, and the slide shaft seat 102 is fixedly connected with the frame 1 by means of bolts. Although the film 6 coiled material can be installed on the film material roller 2 by opening the upper part of the shaft seat 101, the shaft installation precision can be influenced by frequent disassembly and assembly, the sliding shaft seat 102 can be conveniently disassembled or installed by moving along the sliding rail 103, and the sliding shaft seat 102 can be conveniently matched with the compression shaft head 201 by moving along the axial direction of the film material roller 2, so that the installation precision of the sliding shaft seat 102 and the compression shaft head 201 is good, and the film 6 coiled material can be conveniently installed.
As shown in fig. 4, in a further embodiment, the winding roller 3 is formed by splicing a roller main body 301 and a binder 302, the peripheral surface of the roller main body 301 is provided with a notch groove 303, the notch groove 303 penetrates through both ends of the roller main body 301 along the axial direction of the roller main body 301, the binder 302 is engaged with the notch groove 303, and the binder 302 is mounted on the roller main body 301 by bolts, and the binder 302 is used for clamping and fixing the film 6 on the roller main body 301. According to the winding roller 3, when the film 6 is connected to the winding roller 3, one end of the film 6 may be sandwiched between the edge pressing portion 302 and the winding roller body 301, and then the bolts may be tightened.
