This is particularly true during the production of composite current collectors, where the appearance of the membrane materials, including the original current collector membrane and the sputtered semi-finished membrane, is crucial. These materials are ultra-thin and highly sensitive to stress; even slight variations in stress can lead to inaccurate deformation measurements.

[0015] Preferably, a distance sensor is installed at the inner bottom of the limiting slide rail, and a counterweight groove is fixedly installed at the top of the clamping plate.

[0016] Preferably, the fixed block is fixedly connected to both sides of the fixed block, the sliding plate has a limit hole inside, the limit rod passes through the limit hole, the movable rod is fixedly connected to a linear slide bar at one end near the precision electric actuator, the output end of the precision electric actuator is fixedly connected to a linear slide rail, the end of the linear slide rail has a linear groove, and the linear slide bar cooperates with the linear groove.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0020] 1. The inner detection box has rounded corners on both sides, and the extrusion plate is made of PV (polyvinyl chloride) material to prevent scratches. The movable cavity keeps the detection position away from the entrance and exit. The outer light-blocking box is made of opaque material. The inner detection box, side baffles and inner wall of the outer light-blocking box are all frosted and coated with light-absorbing material to prevent reflection and prevent the interior from being interfered with by external light.

[0021] 2. After the clamping plate contacts the membrane material, the lifting lug gradually slides away from the top of the limit slide rail. The lifting lug has a certain amount of room to move inside the limit slider, so that the lifting lug will not press or lift the clamping plate. At this time, the clamping plate is no longer supported by the lifting lug, but is completely supported by the membrane material. Different weights of counterweights can be placed inside to provide a gradient for inspection and measurement, thereby changing the tension of the membrane material and recording the changes in the membrane material. Since the weight of the counterweight is constant, the state of passing under different tensions can be detected, which is convenient for detection and recording and for adjusting the tension. At this time, the tension of the membrane material can be recorded according to the weight of the clamping plate, and the appearance changes of the membrane material can be detected under this tension state.

[0022] 3. A precision motor drives a worm gear to rotate. The worm gear moves outside the turbine, thereby driving a rotating plate to move along the track of an arc-shaped groove, thus adjusting the incident angle of the lighting lamp. This facilitates recording the state of the membrane material under different incident angles. The lighting lamp uses an adjustable light source with an adjustment range of 500-2000 light intensity.

[0042] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0043] This utility model provides, for example Figure 1-11 The deformation inspection device for composite current collector membrane materials shown includes:

[0044] The detection bracket 001 is used for light isolation and includes an outer light-blocking box 101. The front and rear ends of the outer light-blocking box 101 are provided with inlets and outlets 102 for material to pass through.

[0045] The tension assembly 002 is located inside the outer light-blocking box 101, and clamping plate assemblies 003 are installed at both ends. The tension assembly 002 includes a movable rod 201 and a sliding plate 204 slidably connected to the movable rod 201. The clamping plate assembly 003 includes a clamping plate 301, and a pressing plate 308 is installed at the bottom of the clamping plate 301 for clamping the material.

[0046] Width adjustment component 004 is disposed between tension components 002 and includes two symmetrical transverse electric actuators 401. The ends of the transverse electric actuators 401 are connected to the sliding plate 204. The width adjustment component 004 is used to adjust the width of tension components 002.

[0047] like Figure 4 As shown, the arrow points to the adjustment direction of the width adjustment component 004;

[0048] The lighting assembly 005 is installed on the inner top of the outer light shield 101 and includes a lighting lamp 508.

[0049] In use, the user can feed the film material (such as polymer film or film with a metal coating on the surface) into the interior of the detection bracket 001 through the transport roller. The film material passes through the inlet 102 inside the outer light-blocking box 101 in the MD direction. In the initial state, the inner detection box 104 slightly lifts the film material. When detection is required, the inner detection box 104 is lowered and reset to the same plane as the transport roller. At this time, the film material is at zero tension. The inner detection box 104 has rounded corners on both sides to prevent scratches. At this time, the film material is detected by the lighting component 005 and the initial data is recorded.

[0050] A fixing block 103 is fixedly connected to the bottom of the outer light-blocking box 101. An electric push rod is installed above the fixing block 103. The output end of the electric push rod is connected to the inner detection box 104, which facilitates the adjustment of the height of the inner detection box 104. A camera is installed at the bottom of the cover plate to detect changes in the membrane material. The camera uploads the phenomena and size changes of the membrane material to the system in real time for staff to record. Side baffles 105 are provided on both sides of the inner detection box 104. The side baffles 105 are fixedly connected to the outer light-blocking box 101. An avoidance groove 106 is opened inside the side baffles 105. An active cavity 107 is provided inside the outer side of the side baffles 105. The active cavity 107 keeps the detection position away from the entrance 102 to prevent the interior from being interfered with by external light.

[0051] The 104 is equipped with a light detection component located below the membrane material, corresponding to the position of the lighting lamp 508. The light detection component can be configured as a transmittance tester to detect the transmittance of the membrane material. The light intensity absorbed by the lighting lamp 508 is the incident light intensity (I0), and the light intensity detected by the transmittance tester is the light intensity (I). The transmittance (T%) of the membrane material is measured, which is the percentage of the light intensity (I) transmitted through the membrane material to the incident light intensity (I0): T = (I / I0) × 100%, thereby obtaining the light intensity (I).

[0052] The top of the detection bracket 001 is hinged with a cover plate, which is easy to open by hand to replace the counterweight. The outer light-blocking box 101 is made of steel or aluminum and is opaque. The inner detection box 104, the side baffle 105, and the inner sidewall of the outer light-blocking box 101 are all frosted and coated with light-absorbing material to prevent reflection. The top of the outer light-blocking box 101 has a reserved interface for installing the lighting component 005, which is convenient for connecting to an external power source.

[0053] When the tension of the membrane material needs to be adjusted, the user can activate the tension assembly 002. A precision electric actuator 209 is installed on the outside of the outer light-blocking box 101. Two movable rods 201 are provided, located on both sides of the fixed block 103. A hinge rod 202 is hinged to both ends of the movable rod 201. A lifting rod 203 is hinged to the top of the hinge rod 202. A sliding plate 204 is located on the outside of the movable rod 201. A connecting post 205 is fixedly connected to the top of the sliding plate 204. A connecting ear 206 is sleeved on the outside of the connecting post 205. The connecting ear 206 is fixedly connected to the outside of the lifting rod 203. A limiting groove 207 is opened on the inner side of the sliding plate 204. A limiting block 208 is fixedly connected to the outside of the movable rod 201. The limiting block 208 is located inside the limiting groove 207 and is slidably connected to the limiting groove 207.

[0054] By activating the precision electric actuator 209, the precision electric actuator 209 pushes the linear slide bar 404 to move via the linear slide rail 405. The linear slide bar 404 drives the two movable rods 201 to move. The limiting block 208 on the outer side of the movable rod 201 slides inside the limiting groove 207, which facilitates the limiting of the movable rod 201. The movement of the movable rod 201 drives the hinge rod 202 to rotate, thereby driving the lifting rod 203 to descend. Since the connecting ear 206 on the outer side of the lifting rod 203 slides on the outer side of the connecting column 205, it is convenient to limit the lifting rod 203, so that the lifting rod 203 drives the clamping plate assembly 003 to descend and gradually contact the membrane material, thereby squeezing the membrane material so that the membrane material is tightly attached to and straightened by the inner detection box 104. In the original state, the tension is related to the overall weight of the clamping plate 301. When the lifting ear 304 moves away from the top of the fixed ear 302, that is, the clamping plate 301 is lifted by the membrane material, and then the change of the membrane material is detected and recorded again.

[0055] A fixing lug 302 is fixedly connected to the top of the clamping plate 301. A limiting slide rail 303 is provided inside the fixing lug 302. A lifting lug 304 is fixedly connected to the inner side of the lifting rod 203. A limiting slider 305 is fixedly connected to the end of the lifting lug 304. The limiting slider 305 is slidably connected to the limiting slide rail 303. When the clamping plate 301 contacts the membrane material, the lifting lug 304 gradually slides away from the top of the limiting slide rail 303 and approaches the distance sensor 306. The distance sensor 306 is connected to the PLC controller, detects the position of the lifting lug 304, and uploads the data. The C controller controls the precision electric actuator 209 according to the detected position, so that the lifting lug 304 will not press or lift the clamping plate 301. At this time, the clamping plate 301 is no longer supported by the lifting lug 304, but is completely supported by the membrane material. At this time, the tension of the membrane material can be recorded according to the weight of the clamping plate 301, and the appearance change of the membrane material can be detected under this tension state. The bottom of the clamping plate 301 is fixedly connected to the extrusion plate 308, which is made of PV material. The inner bottom of the limiting slide rail 303 is equipped with a distance sensor 306, and the top of the clamping plate 301 is fixedly installed with a counterweight groove 307.

[0056] The counterweight groove 307 of the clamping plate 301 can hold counterweights of different weights. The weights of the counterweights are divided into five groups of 5N / 10N / 20N / 40N / 100N to provide a gradient for inspection and measurement, thereby changing the tension of the membrane material and recording the changes in the membrane material. Since the weight of the counterweights is constant, the state of the membrane material under different tensions can be detected, which is convenient for detection and recording.

[0057] When replacing the counterweight, the user can first lift the clamping plate assembly 003, replace the counterweight, and then slowly lower the clamping plate assembly 003 to contact the membrane material to prevent the membrane material from being damaged due to excessive instantaneous tension changes.

[0058] Limiting rods 402 are fixedly connected to both sides of the fixed block 103. Limiting holes 403 are opened inside the sliding plate 204. The limiting rods 402 pass through the limiting holes 403. A linear slide bar 404 is fixedly connected to one end of the movable rod 201 near the precision electric push rod 209. A linear slide rail 405 is fixedly connected to the output end of the precision electric push rod 209. A linear slide groove 406 is opened at the end of the linear slide rail 405. The linear slide bar 404 cooperates with the linear slide groove 406. By activating the transverse electric push rod 401, the two sliding plates 204 can be pushed to move. The sliding plates 204 slide outside the limiting rods 402, which facilitates limiting and thus facilitates adjusting the distance between the two clamping plate assemblies 003, and facilitates adjusting the detection width as needed.

[0059] An installation plate 501 is installed at the reserved interface on the top of the outer light box 101. A scale plate 502 is fixedly connected to the bottom of the installation plate 501. A turbine 503 is fixedly connected to the bottom of the installation plate 501. A rotating plate 505 is slidably connected to the outer side of the scale plate 502. A precision motor 506 is installed on the side of the rotating plate 505. A worm gear 507 that cooperates with the turbine 503 is fixedly connected to the output end of the precision motor 506. An arc-shaped groove 504 is opened on the side of the scale plate 502. A protrusion is fixedly connected to the inner side of the rotating plate 505. The protrusion cooperates with the arc-shaped groove 504. A lighting lamp 508 is installed at the bottom of the rotating plate 505.

[0060] During testing, the user can start the precision motor 506, which drives the worm gear 507 to rotate. The worm gear 507 moves outside the turbine 503, thereby driving the rotating plate 505 to move along the track of the arc groove 504, thus adjusting the incident angle of the illumination lamp 508, which is convenient for recording the state of the membrane material under different incident angles. The illumination lamp 508 uses an adjustable light source with an adjustment range of 500-2000 light intensity.

[0061] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
