Description

Technical Field

[0001] The present application relates to the technical field of film detection, and in particular to a film peeling force detection device. Background Art

[0002] When producing the current collector, a metal layer is usually deposited on the polymer base film by evaporation, magnetron sputtering or water electroplating, and the metal layer is bonded to the polymer base film.

[0003] When the current collector is in use, its conductivity and other properties will be affected by the bonding force between the metal layer and the polymer base film. If the bonding force between the two is low, the metal layer and the polymer base film will separate and peel off during the subsequent current collector processing, resulting in current collector failure. Therefore, the bonding force test between the base film and the metal layer is very important.

[0004] At present, there are two main methods for testing the adhesion between the base film and the metal layer: one is to manually stick the tape to the surface of the metal layer, then tear off the tape, and observe the adhesion with the naked eye, but this method has a large human subjective factor, which can easily lead to inaccurate adhesion test; the other is to use a tensile testing machine to stick the tape to the surface of the metal layer, and then use the tensile testing machine to tear the tape. When the metal layer is separated from the base film surface, the value displayed by the tensile testing machine is the adhesion between the base film and the metal layer. However, during the tearing process, the arc of the metal layer is large when it is separated, and creases are easily formed on the metal layer, which affects the test results of the tensile testing machine. In addition, the operation is difficult and inconvenient. Utility Model Content

[0005] The main purpose of the present application is to provide a film peeling force detection device to solve the problems in the prior art that the test method for the adhesion between the base film and the metal layer is inaccurate, difficult to operate, and inconvenient.

[0035] See also Figures 1 to 4 As shown, the present application provides a film peeling force detection device, hereinafter referred to as a detection device, which includes a housing 10, a rotating mechanism 30 and a fixed separation mechanism 40.

[0036] Among them, the shell 10 has a accommodating cavity 101, and the inner surface of the shell 10 is provided with a sensing part 20 along the circumference of the shell 10; the rotating mechanism 30 is rotatably arranged in the accommodating cavity 101, and the rotating mechanism 30 rotates along the circumferential direction of the first circle; the fixed separation mechanism 40 is arranged on the rotating mechanism 30, and the fixed separation mechanism 40 includes a fixing component 41 and a separation component 42 arranged in sequence along the radial direction of the first circle, the fixing component 41 is connected to the rotating mechanism 30, and there is an accommodating gap 401 for placing the film 80 between the fixing component 41 and the separation component 42, and a connecting part 50 is provided on the side of the fixing component 41 close to the accommodating gap 401 and the side of the separation component 42 close to the accommodating gap 401, and the connecting part 50 is at least used to be fixedly connected with the film 80, and the separation component 42 has a first position that is subjected to the centrifugal force applied when the rotating mechanism 30 rotates so as to be separated from the fixing component 41 and contact with the sensing part 20.

[0037] In this embodiment, when the detection device is actually used, there is an accommodating gap 401 for placing the film 80 between the fixing component 41 and the separating component 42, and the fixing component 41 is close to the accommodating gap 401. The side of the accommodating gap 401 and the side of the separating component 42 are close to the accommodating gap 401 are both provided with a connecting portion 50, and the film 80 includes a base film 81 and a metal layer 82 deposited on one surface of the base film 81 (see Figure 3As shown in the figure, when the bonding force between the base film 81 and the metal layer 82 needs to be tested, the film 80 only needs to be placed in the accommodation gap 401, and then the surface of the base film 81 away from the metal layer 82 is connected to the fixed component 41 through the connecting portion 50, and the surface of the metal layer 82 away from the base film 81 is connected to the separation component 42. After the film 80 is placed, the fixed separation mechanism 40 with the film 80 is installed on the rotating mechanism 30. At this time, the fixed component 41 is connected to the rotating mechanism 30. Then the rotating mechanism 30 is turned on. Since the rotating mechanism 30 can rotate along the circumferential direction of the first circle, it can drive the fixed separation mechanism 40 to rotate along the circumferential direction of the first circle. In this process, the separation component 42 is affected by the centrifugal force and has a tendency to move toward the housing 10. However, since the fixing component 41 and the separation component 42 are connected to the film 80 via the connection portion 50, when the centrifugal force exerted on the separation component 42 is smaller than the bonding force between the base film 81 and the metal layer 82, the separation component 42 is always connected to the film 80 and will not be thrown out due to the centrifugal force. At this time, it is necessary to gradually increase the rotation speed of the rotating mechanism 30 to increase the centrifugal force exerted on the separation component 42; when the centrifugal force exerted on the separation component 42 is greater than the bonding force between the base film 81 and the metal layer 82, the separation component 42 will be thrown out with the metal layer 82, so that the metal layer 82 is separated from the base film 81. Since the outer shell 10 is provided with a sensing part 20 along its circumferential inner surface, the separation component 42 will come into contact with the sensing part 20 after being thrown out, and the sensing part 20 will record the signal generated by the impact. At this time, the centrifugal force when the separation component 42 is thrown out is the bonding force between the base film 81 and the metal layer 82, and the bonding force between the base film 81 and the metal layer 82 can be calculated by detecting the rotation speed of the rotating mechanism 30 at this time.

[0038] That is to say, compared with the detection device of the bonding force between the base film 81 and the metal layer 82 in the prior art, the present application controls the rotation speed of the rotating mechanism 30 to apply corresponding centrifugal force to the separation component 42, and uses the centrifugal force when the separation component 42 is thrown out as the bonding force between the base film 81 and the metal layer 82, and the magnitude of the bonding force can be calculated by detecting the rotation speed of the rotating mechanism 30. With such a configuration, the bonding force between the base film 81 and the metal layer 82 can be quickly detected, the operation is convenient and fast, and there is no need for manual judgment by the naked eye, which reduces labor costs and improves the accuracy of the bonding force detection method to a certain extent. At the same time, after the separation component 42 of the present application is thrown out, the metal layer 82 can be peeled off on the entire surface, and there is no problem of bending curvature, which effectively avoids the measurement error caused by the peeling bending curvature in the prior art, thereby making the measurement more accurate.

[0039] Specifically, the film 80 in the present application may also be a base film 81 and a metal layer 82 deposited on both surfaces of the base film 81 (see Figure 4As shown), wherein the fixing component 41 is connected to the metal layer 82 on one side of the two surfaces through the connecting portion 50, and the separating component 42 is connected to the metal layer 82 on the other side of the two surfaces through the connecting portion 50.

[0040] It should be noted that, in the present application, when the film 80 includes a base film 81 and a metal layer 82 deposited on both surfaces of the base film 81, the bonding force between the fixed component 41 and the metal layer 82, and the bonding force between the separation component 42 and the metal layer 82 are greater than the bonding force between each metal layer 82 and the base film 81; when the film 80 includes a base film 81 and a metal layer 82 deposited on one surface of the base film 81, the bonding force between the fixed component 41 and the base film 81, and the bonding force between the separation component 42 and the metal layer 82 are greater than the bonding force between the base film 81 and the metal layer 82. In this way, it can be ensured that when the separation component 42 is thrown out by the centrifugal force, the separation component 42 will not separate from the metal layer 82, and the film 80 will not separate from the fixed component 41, thereby ensuring the accuracy of the detection result.

[0041] It should be noted that the present application defines the first rotation path of the rotating mechanism 30 when it starts to rotate as a “first circle”; the “first position” in the present application is any position where the separation component 42 falls on the sensing part 20 .

[0042] Further, see Figures 2 to 4 As shown, the fixed assembly 41 in this embodiment includes a fixed block 411 and a support block 412. The fixed block 411 is fixedly connected to the rotating mechanism 30, and a connecting portion 50 is provided on one side of the fixed block 411 close to the accommodating gap 401; the support block 412 is provided on the fixed block 411 and extends in a direction close to the separation assembly 42. Specifically, in this embodiment, the fixed block 411 is fixedly connected to the rotating mechanism 30, which can prevent the fixed block 411 from being separated from the rotating mechanism 30 during the rotation of the rotating mechanism 30, thereby ensuring that when the separation assembly 42 is thrown out by centrifugal force, the base film 81 is still connected to the fixed block 411, thereby ensuring the stability of the operation of the detection device; and the existence of the support block 412 can support the separation assembly 42, avoiding the separation assembly 42 from falling due to gravity before starting to work, resulting in the separation of the metal layer 82 and the base film 81, ensuring that the separation assembly 42 is only thrown out by the centrifugal force, thereby improving the accuracy of the detection result.

[0043] Further, see Figure 2As shown, the separation component 42 in this embodiment includes a separation block 421, which is arranged on the support block 412, and a connecting portion 50 is arranged on one side of the separation block 421 close to the accommodating gap 401. The separation block 421 of this embodiment is connected to the metal layer 82 of the film 80 through the connecting portion 50. When the rotating mechanism 30 starts to rotate, the separation block 421 is subjected to the centrifugal force and has a tendency to move toward the direction of the housing 10. When the centrifugal force on the separation block 421 is greater than the bonding force between the base film 81 and the metal layer 82, the separation block 421 is thrown out with the metal layer 82 and thrown to the first position, so that the metal layer 82 is separated from the base film 81, and the whole process is simple and convenient. It can be understood that the separation block 421 has a predetermined mass, which facilitates the separation of the separation block 421 from the fixed block 411. Among them, the predetermined mass is not specifically limited in this application and can be designed according to actual processing requirements.

[0044] Furthermore, the connecting portion 50 in this embodiment includes an adhesive layer. That is, in this embodiment, the metal layer 82 can be bonded to the separation block 421 and the base film 81 can be bonded to the fixed block 411 through the adhesive layer, so as to ensure that there is high adhesion between the separation block 421 and the metal layer 82, and between the fixed block 411 and the base film 81, to prevent the metal layer 82 from being separated from the base film 81 when the rotating mechanism 30 rotates, and only the separation block 421 is thrown out, or to prevent the base film 81 from detaching from the fixed block 411 and causing the entire film 80 to be thrown out with the separation block 421.

[0045] Optionally, the adhesive layer may be glue or double-sided tape, as long as it can ensure that the bonding force between the separation block 421 and the metal layer 82, and between the fixing block 411 and the base film 81 is greater than the bonding force between the base film 81 and the metal layer 82. This application does not make any specific limitations, and any other deformation methods based on the concept of this application are within the protection scope of this application.

[0046] Further, see Figure 1As shown, in this embodiment, a mounting seat 60 is provided in the housing 10, and the rotating mechanism 30 includes a driving motor 31, a first rotating shaft 32, and a second rotating shaft 33. The driving motor 31 is provided on the mounting seat 60; the first rotating shaft 32 extends along the axial direction of the first circle and is drivingly connected to the driving motor 31, so as to rotate along the circumferential direction of the first circle under the drive of the driving motor 31; the second rotating shaft 33 is fixedly provided on the first rotating shaft 32 and extends along the radial direction of the first circle, and the first end 331 of the second rotating shaft 33 is provided with a fixing and separating mechanism 40. The first rotating shaft 32 can support the second rotating shaft 33, and when the driving motor 31 is working, the first rotating shaft 32 itself rotates and drives the second rotating shaft 33 to rotate synchronously, thereby improving the response speed of the rotation transmission; and the second rotating shaft 33 can support the fixing and separating mechanism 40. In this embodiment, the first rotating shaft 32 is driven to rotate by the driving motor 31, thereby driving the second rotating shaft 33 to rotate, so that the fixed separation mechanism 40 is subjected to centrifugal force, and the separation component 42 is thrown out with the metal layer 82 under the action of the centrifugal force. The entire separation process does not require manual participation, which reduces labor costs and time costs. In addition, in this embodiment, the first rotating shaft 32 and the second rotating shaft 33 can be rotated by a driving motor 31, which is easy to operate, and the number of driving motors 31 set is reduced to a certain extent, making the detection device as a whole more lightweight and reducing costs.

[0047] Further, see Figures 1 to 4 As shown, the film peeling force detection device in this embodiment further includes a balancing block 70, which is disposed at the second end 332 of the second rotating shaft 33 opposite to the first end 331. In this way, during the rotation of the second rotating shaft 33, the first end 331 and the second end 332 thereof can maintain balance, thereby preventing the second rotating shaft 33 from shaking, reducing the wear of the connection between the second rotating shaft 33 and the first rotating shaft 32, and extending the service life of the entire driving mechanism to a certain extent.

[0048] Furthermore, the housing 10 in this embodiment is an annular housing (see Figure 1 As shown in the figure, a shell cover is provided on the annular shell (the shell cover is not shown in the figure), and the shell cover is connected to the annular shell to seal the accommodating chamber 101. In this embodiment, the shell 10 is set as an annular shell, which can ensure that the distance between the separation component 42 and the inner surface of the shell 10 is always equal during the rotation process. In this process, no matter when the separation component 42 is thrown out, it can quickly contact the sensing part 20, which improves the accuracy of the detection device to a certain extent; and the existence of the shell cover can prevent the separation component 42 from flying out of the accommodating chamber 101 when it is thrown out by centrifugal force.

[0049] Furthermore, the inner surface of the shell cover and the inner surface of the annular shell in this embodiment are both provided with a sensing portion 20. In this way, no matter where the separation component 42 with the metal layer 82 falls when being thrown out by centrifugal force, it can contact the sensing portion 20, effectively ensuring the normal operation of the detection device.

[0050] Furthermore, the sensing part 20 in this embodiment includes a strain gauge sensor. Specifically, the strain gauge sensor includes a resistive strain gauge sensor, which reflects the degree of physical force or deformation through a changing resistance value, thereby realizing the measurement of force. The strain gauge sensor has the advantages of high precision, high sensitivity, and fast response speed. When the separation component 42 contacts the sensing part 20, the strain gauge sensor can respond quickly, thereby improving the accuracy of the detection result.

[0051] Furthermore, the film peeling force detection device in this embodiment also includes a controller and a data processor (neither the controller nor the data processor is shown in the drawings), the controller is in communication connection with the drive motor 31 and the sensing part 20, the controller controls the rotation speed of the drive motor 31 according to the signal transmitted by the sensing part 20, and the data processor is in communication connection with the controller to process the signal transmitted by the controller. That is to say, in this embodiment, the controller controls the opening and closing of the drive motor 31 and the rotation speed of the drive motor 31; the sensing part 20 senses the first position where the separation component 42 contacts the sensing part 20; and the data processor processes the signal transmitted by the controller and calculates the magnitude of the centrifugal force.

[0052] Specifically, the working principle of the film peeling force detection device of the present application is as follows:

[0053] First, the fixing block 411 is connected to the base film 81 of the film 80 through the connecting portion 50, and the separating block 421 is connected to the metal layer 82 of the film 80. At this time, the separating block 421 is located on the supporting block 412. Then, the fixing block 411 is fixedly connected to the first end 331 of the second rotating shaft 33, and the balancing block 70 is fixedly connected to the second end 332 of the second rotating shaft 33, so that the second rotating shaft 33 is kept balanced.

[0054] Secondly, the driving motor 31 is turned on by the controller to drive the first rotating shaft 32 to rotate along the circumferential direction of the first circle, thereby driving the second rotating shaft 33 to rotate along the circumferential direction of the first circle, so that the separation block 421 is subjected to the centrifugal force applied by the rotating mechanism 30 when rotating, so that it has a tendency to move toward the direction of the shell 10; when the centrifugal force exerted on the separation block 421 is less than the bonding force between the base film 81 and the metal layer 82, the separation block 421 is always connected to the film 80 and will not be thrown out due to the centrifugal force. At this time, the speed of the driving motor 31 is gradually increased by the controller, thereby increasing the centrifugal force exerted on the separation block 421; when the centrifugal force exerted on the separation block 421 is greater than the bonding force between the base film 81 and the metal layer 82, the separation block 421 will be thrown out with the metal layer 82 detached from the base film 81, and the metal layer 82 is separated from the base film 81;

[0055] Then, the thrown-out separation block 421 contacts the sensing part 20, and the sensing part 20 transmits the sensed signal to the controller. The controller automatically records the rotation speed of the driving motor 31 according to the signal transmitted by the sensing part 20, and transmits the rotation speed to the data processor; the data processor processes the detection result to calculate the centrifugal force when the separation block 421 is thrown out, and the centrifugal force is the bonding force between the base film 81 and the metal layer 82.

[0056] On the other hand, the embodiment of the present application also provides a detection method of a film peeling force detection device, hereinafter referred to as the detection method, the detection method includes the above-mentioned film peeling force detection device, and therefore, the detection method includes all the technical effects of the above-mentioned film peeling force detection device. Since the technical effects of the film peeling force detection device have been described in detail above, they will not be repeated here.

[0057] Furthermore, the detection method of the film peeling force detection device in this embodiment includes:

[0058] Step S1: measuring the mass M1 of the fixed block 411, the mass M2 of the separation block 421, and the mass M3 of the film 80, bonding the film 80 to the fixed block 411 and the separation block 421, and preparing a balancing block 70 with a mass M4, wherein M4=M1+M2+M3;

[0059] Step S2: fixedly connecting the fixed separation mechanism 40 having the film 80 to the first end 331 of the second rotating shaft 33, fixedly connecting the balancing block 70 to the second end 332 of the second rotating shaft 33, and measuring the distance R between the center of mass of the separation block 421 and the center of mass of the connection between the second rotating shaft 33 and the first rotating shaft 32;

[0060] Step S3: The driving motor 31 is turned on by the controller, and the speed of the driving motor 31 is slowly increased from small to large. The fixed separation mechanism 40 performs a circular motion, and the separation block 421 is subjected to the centrifugal force. When the centrifugal force is greater than the bonding force between the base film 81 and the metal layer 82, the separation block 421 will be thrown out; the thrown separation block 421 falls onto the inner surface of the housing 10 having the sensing part 20, and the sensing part 20 senses that an object has fallen. The controller automatically records the rotation speed W of the driving motor 31 and transmits the detection result to the data processor;

[0061] Step S4: Calculate the bonding force F between the base film 81 and the metal layer 82 by a data processor, where F = M1 × W 2 ×R.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0063] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0064] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
