[0042] As attached Figure 1 As shown, the peeling test device for a wearable flexible electronic device proposed in the utility model includes a main body, which includes a peeling mechanism 10, an adjusting mechanism 20, a first bearing mechanism 30, a second bearing mechanism 40 and a measuring mechanism 50. The adjusting mechanism 20 is connected to the first bearing mechanism 30, and the first bearing mechanism 30 is used to be detachably connected to the test piece. The second bearing mechanism 40 is located on one side of the first bearing mechanism 30, and the second bearing mechanism 40 is used to be fixedly connected to the test piece. The adjusting mechanism 20 is used to adjust the angle of the first bearing mechanism 30 relative to the second bearing mechanism 40 so that the test piece is at the peeling angle required for the test. The peeling mechanism 10 is used to adjust the relative position of the first bearing mechanism 30 or the second bearing mechanism 40 to change the distance between the first bearing mechanism 30 and the second bearing mechanism 40. During this process, the test piece is subjected to force until the test piece is separated from the first bearing mechanism 30. At this time, the peeling of the test piece is completed. The measuring mechanism 50 is used to measure the peeling force of the test piece.
[0043] The first carrying mechanism 30 cooperates with the second carrying mechanism 40 to place the test piece, wherein the first carrying mechanism 30 is detachably connected to the test piece so that the test piece can be separated from the first carrying mechanism 30 to realize the peeling of the test piece;
[0044] The adjustment mechanism 20 is connected to the first bearing mechanism 30 and is used to adjust the angle of the first bearing mechanism 30 relative to the second bearing mechanism 40, so as to adjust the peeling angle of the test piece according to the test requirements, so as to verify whether the interface adhesion of the test piece at different peeling angles meets the requirements;
[0045] The peeling mechanism 10 is used to change the relative position of the first bearing mechanism 30 and the second bearing mechanism 40 so that the test piece can be separated from the first bearing mechanism 30, thereby completing the peeling test; the peeling mechanism 10 cooperates with the adjustment mechanism 20 to test the peeling strength of the test piece at different angles according to actual needs, and the peeling force of the test piece can be measured by the measuring mechanism 50;

[0047] It can be understood that the fixed connection between the second supporting mechanism 40 and the test piece means that during the peeling test, the test piece will not be separated from the fixation of the second supporting mechanism 40, but will always maintain a "connected" and inseparable relationship, which does not mean that the test piece and the second supporting mechanism 40 cannot be separated once they are fixed.
[0048] In one embodiment of the present invention, Figure 1 and attached Figure 2 The peeling mechanism 10 includes a base 11 and a connecting seat 12.

The connecting seat 12 is configured to move in the up and down directions relative to the base 11 to adjust the position of the first supporting mechanism 30 relative to the second supporting mechanism 40. When the connecting seat 12 moves upward relative to the base 11, the distance between the first supporting mechanism 30 and the second supporting mechanism 40 increases. At this time, the test piece is subjected to the peeling force and can gradually fall off from the first supporting mechanism 30 to complete the peeling.
[0049] In another embodiment of the utility model, the connecting seat 12 is used to install the second supporting mechanism 40, and the connecting seat 12 is configured to be movable in the up and down directions relative to the base 11 to adjust the position of the second supporting mechanism 40 relative to the first supporting mechanism 30. When the connecting seat 12 moves upward relative to the base 11, the distance between the second supporting mechanism 40 and the first supporting mechanism 30 increases. At this time, the test piece is subjected to the peeling force and can gradually fall off from the first supporting mechanism 30 to complete the peeling.

The transmission seat 121 is movably connected to the screw rod 13 through the screw rod hole 122. When the screw rod 13 rotates around its own axis, the transmission seat 121 can move along the axial direction of the screw rod 13, that is, in the up and down directions, thereby realizing the movement of the connecting seat 12 and the first supporting mechanism 30 or the second supporting mechanism 40 installed thereon in the up and down directions.
[0051] In one example, as shown in the attached Figure 2 As shown, the transmission assembly also includes a driving member 14, which is connected to the screw rod 13 and is used to drive the screw rod 13 to rotate around its own axis. The setting of the driving member 14 can realize automatic control, which saves manpower and improves the accuracy of control compared to manual adjustment of the rotation of the screw rod 13, which is conducive to improving the stripping efficiency and avoiding the interference of human factors on the test results. Optionally, the driving member 14 adopts a stepping motor, and the output shaft of the stepping motor is connected to the screw rod 13.
[0052] In one example, as shown in the attached Figure 2 As shown, the transmission assembly also includes a speed reducer 15 and a coupling 16. The driving member 14 is connected to the screw rod 13 through the speed reducer 15 and the coupling 16. The speed reducer 15 is used to achieve high-efficiency and high-precision speed reduction, and can increase the output torque of the screw rod 13, which is beneficial to improving the transmission efficiency and accurately driving the connecting seat 12 to move in the up and down direction. Optionally, the speed reducer 15 adopts a planetary reducer.
[0053] In one example, in conjunction with the attached Figure 2 and attached Figure 3 The base 11 includes a housing chamber 111, a screw rod 13 is installed in the housing chamber 111, one end of the screw rod 13 is rotatably connected to the lower chamber wall of the housing chamber 111, and the other end passes through the upper chamber wall of the housing chamber 111 and is directly connected to the driving member 14, or is connected to the driving member 14 through a coupling 16 and a speed reducer 15. The screw rod 13 is rotatable relative to the upper chamber wall of the housing chamber 111, and the coupling 121 can make the connecting seat 12 move in the up and down direction through the cooperation between the screw rod 13 and the transmission seat 121. Optionally, the screw rod 13 is connected to the chamber wall of the housing chamber 111 through a bearing.
[0054] In one example, in conjunction with the attached Figure 2 and attached Figure 3A limiting groove 112 is provided on the base 11, and the limiting groove 112 is connected to the accommodating cavity 111. The limiting groove 112 is configured to penetrate the base 11 along the front-to-back direction to form a guide member 113 on the base 11. The upper and lower ends of the guide member 113 are connected to the base 11. The connecting seat 12 includes a mounting plate 123 connected to the transmission seat 121. The transmission seat 121 is located in the accommodating cavity 111 of the guide member 113 and the limiting groove 112. The mounting plate 123 is located on the side of the guide member 113 away from the limiting groove 112. The mounting plate 123 is used to install the adjustment mechanism 20 or the second supporting mechanism 40.
[0055] Optionally, the transmission seat 121 contacts one side of the guide member 113 close to the limiting groove 112, and the guide member 113 can guide the transmission seat 121, so that the transmission seat 121 can stably and efficiently change its position in the up and down directions, thereby ensuring the stability of the overall structure.
[0056] Optionally, the mounting plate 123 contacts the side of the guide member 113 away from the limiting groove 112, and the guide member 113 can guide the mounting plate 123, so that the mounting plate 123 and the adjustment mechanism 20 installed thereon can stably and efficiently produce position changes in the up and down directions, thereby ensuring the stability of the overall structure.
[0057] As attached Figure 2 As shown, a guide groove 124 is provided at the connection between the mounting plate 123 and the transmission seat 121. The guide groove 124 penetrates the connection between the mounting plate 123 and the transmission seat 121 in the up-down direction, and penetrates the front end or rear end of the connection between the mounting plate 123 and the transmission seat 121 in the front-to-back direction. The guide groove 124 cooperates with the guide member 113. When the transmission seat 121 is connected to the screw rod 13 through the screw rod hole 122, the guide member 113 is partially accommodated in the guide groove 124. When the screw rod 13 cooperates with the transmission seat 121 to move the connecting seat 12 in the up-down direction, the guide member 113 and the guide groove 124 are slidably matched, which is conducive to ensuring stability and efficiency in the stripping process and ensuring the accuracy of the test results.

The support member 21 is used to connect with the connecting seat 12. More specifically, the support member 21 is connected with the mounting plate 123. The movable member 22 is used to connect with the first bearing mechanism 30 to drive the first bearing mechanism 30 to rotate relative to the support member 21, so that the angle of the first bearing mechanism 30 relative to the second bearing mechanism 40 changes, thereby realizing the adjustment of the peeling angle of the test piece.
[0060] In one example, the support member 21 is configured as a circular plate, and the movable member 22 is configured as a circular plate, which can realize free adjustment of the peeling angle from 0° to 180°, and realize full-angle peeling test. Optionally, the support member 21 and the movable member 22 are made of aluminum alloy plates, which have a certain structural strength and are conducive to extending the service life.

[0063] In one example, the diameter of the movable part 22 is smaller than the diameter of the support part 21. The support part 21 is provided with a scale mark on a surface of one side close to the movable part 22. The scale mark is set at a position where the support part 21 is exposed from the movable part 22 to facilitate observation of the rotation angle of the movable part 22 relative to the support part 21.
[0064] In another example, the diameter of the movable part 22 is smaller than the diameter of the support part 21, and the adjustment mechanism 20 includes a dial 23, which is installed at one end of the support part 21 close to the movable part 22.

[0069] In one example, the adjustment mechanism 20 includes a fixed platform 24, which is connected to a side of the movable part 22 away from the support member 21, and the fixed platform 24 is used to install the first supporting mechanism 30. The dial 23 is provided with an avoidance groove 232, and the avoidance groove 232 is used to avoid the fixed platform 24 and the movable part 22.
[0070] Optionally, the fixed platform 24 and the movable member 22 are detachably connected to facilitate disassembly and assembly.

[0075] Optionally, the back plate 25 is configured as a circular plate, the diameter of which is configured as 110 mm, and the thickness of which is configured as 10 mm. Furthermore, the back plate 25 is configured as an aluminum alloy plate, which has a certain structural strength and is conducive to extending the service life.
[0076] In one embodiment of the present invention, as shown in the attached Figure 5 As shown, the first supporting mechanism 30 includes a support platform 31, which is connected to the movable part 22. When the adjusting mechanism 20 includes a fixed platform 24, the support platform 31 is connected to the fixed platform 24. A limiting member 32 is protruded from one end of the support platform 31 close to the adjusting mechanism 20. The limiting member 32 is arranged in cooperation with the support member 21 to limit the rotation of the movable part 22 and the fixed platform 24 so that the movable part 22 remains fixed after being adjusted to a desired angle. When the movable part 22 is adjusted to a desired test angle, the limiting member 32 is adjusted to fix the movable part 22 so that it cannot rotate relative to the support member 21, so that the first supporting mechanism 30 can maintain a constant peeling angle during the peeling process to ensure the accuracy of the test.
[0077] In one example, the support 31 is a flat plate, which is set to a rectangular plate. The length of the support 31 is set to 120 mm, the width is set to 100 mm, and the thickness is set to 10 mm. Of course, the support 31 can also be set to other sizes. Those skilled in the art can select the size of the support 31 according to actual testing requirements. The test piece is pasted on the support 31. In this example, the length range of the test piece that can be pasted on the support 31 is 0 to 120 mm, and the width range is 0 to 65 mm.
[0078] It is understandable that the wearable flexible electronic device itself has an adhesive structure, such as a patch with a gel area, etc. Therefore, no additional adhesive is required to detachably fix the test piece to the support 31. Of course, other medical reagents can also be added to the patch structure according to the actual use requirements of the wearable flexible electronic device.
[0079] In one example, a limiting hole 321 is provided on the limiting member 32, and the position of the limiting hole 321 corresponds to the position of the support member 21. The limiting hole 321 penetrates the limiting member 32 along the front-to-back direction. The limiting hole 321 is used to install a clamp. When the movable member 22 is rotated to a desired angle relative to the support member 21, the clamp is installed in the limiting hole 321 so that the end of the clamp contacts the support member 21 and exerts a force on the side of the support member 21, so that the rotation of the movable member 22 is blocked and cannot rotate around its own axis. Through the cooperation of the limiting member 32 and the clamp, the angle of the movable member 22 can be fixed so that the support platform 31 maintains a fixed angle, which is convenient for testing the peeling strength of the test piece at the set angle.
[0080] In another example, when the adjustment mechanism 20 includes a dial 23, the opening position of the limit hole 321 corresponds to the position of the dial 23 to reduce the size of the limit member 32. The limit hole 321 penetrates the limit member 32 in the front-to-back direction. The limit hole 321 is used to install a clamp. When the movable member 22 is rotated to a desired angle relative to the support member 21, the clamp is installed in the limit hole 321 so that the end of the clamp contacts the dial 23 and exerts a force on the side of the dial 23 to hinder the rotation of the movable member 22 and prevent it from rotating around its own axis. Through the cooperation of the limit member 32 and the clamp, the angle of the movable member 22 can be fixed so that the support 31 maintains a fixed angle, which is convenient for testing the peel strength of the test piece at the set angle.
[0081] Optionally, the limiting hole 321 is set as a screw hole, the clamping piece adopts a bolt, and the axial length dimension of the clamping piece is greater than the hole depth of the limiting hole 321. The end of the clamping piece can pass through the limiting hole 321 and contact the support piece 21 or the dial 23. Through the threaded cooperation between the clamping piece and the limiting hole 321, a locking force can be provided between the clamping piece and the support piece 21 or the dial 23 to fix the support 31 to the desired peeling angle.
[0082] Optionally, the limiting member 32 and the support platform 31 are integrally formed.
[0083] Optionally, two limit members 32 are provided and protrude from the front and rear ends of the support platform 31 close to the adjustment mechanism 20. The provision of two limit members 32 can improve the fixing quality and enable the support platform 31 to be maintained at a fixed angle, so that the peeling test result is accurate.
[0084] In one example, the first supporting mechanism 30 includes a connecting member 33, which is located at the lower end of the support platform 31 and connected to the support platform 31. A fixing hole 241 is provided at one end of the fixed platform 24 close to the support platform 31, and an opening that cooperates with the fixing hole 241 is provided at one end of the connecting member 33 close to the fixed platform 24. The fixing hole 241 cooperates with the opening to realize the connection between the fixed platform 24 and the support platform 31.
[0085] Optionally, the fixing hole 241 and the opening are both configured as screw holes, and the fixing platform 24 and the connecting member 33 are connected by screw connection, which is convenient for assembly and disassembly and for later maintenance and repair.
[0086] Optionally, a matching piece 34 corresponding to the connecting piece 33 is provided at the lower end of the support 31. The matching piece 34 and the connecting piece 33 are symmetrically arranged to keep the support 31 balanced and stable. When the support 31 fixes the test piece, the base material can be clamped by the cooperation of the connecting piece 33 and the matching piece 34. The base material can be set to pigskin leather, etc., to simulate the surface of human skin. The test piece is pasted on the base material. Compared with directly pasting it on the support 31, the accuracy and authenticity of the peeling test can be improved.
[0087] In one embodiment of the present invention, Figure 1 and attached Figure 6 The second supporting mechanism 40 includes a first clamping member 41 and a second clamping member 42. The first clamping member 41 and the second clamping member 42 are used to fix the end of the test piece that is not fixed by the first supporting mechanism 30. The first clamping member 41 can move relative to the second clamping member 42. Under the action of an external force, the first clamping member 41 can move closer to and / or away from the second clamping member 42 to change the distance between the first clamping member 41 and the second clamping member 42. When the first clamping member 41 approaches the second clamping member 42, the distance is reduced, and the test piece can be clamped and fixed. When the first clamping member 41 is away from the second clamping member 42, the test piece can be removed.
[0088] In one example, the first clamping member 41 and the second clamping member 42 are symmetrically arranged and fixed by bolts to prevent the test piece from being separated from the second supporting mechanism 40 .
[0089] In one example, the measuring mechanism 50 includes a force sensor located on the second supporting mechanism 40 , the force sensor is disposed on at least one of the first clamping member 41 and the second clamping member 42 , and the force sensor is used to measure the peeling force of the test piece.
[0090] In one example, as shown in the attached Figure 6As shown, the second supporting mechanism 40 also includes an adjusting component, which is used to adjust the positions of the first clamping member 41 and the second clamping member 42 relative to the first supporting mechanism 30. More specifically, the adjusting component is used to adjust the positions of the first clamping member 41 and the second clamping member 42 relative to the support platform 31. Since the specifications and sizes of the test pieces are different, and the peeling angles set during the test process of the test pieces of the same specifications and sizes are different, it is necessary to adjust the positions of the first clamping member 41 and the second clamping member 42 to ensure the fixing quality of the test pieces.
[0091] As attached Figure 6 As shown, the adjustment assembly includes a first adjustment seat 43 and a second adjustment seat 44. The first adjustment seat 43 is used to connect with the second clamping member 42. The first clamping member 41 and the first adjustment seat 43 may be connected or disconnected. The distance between the first clamping member 41 and the second clamping member 42 can be controlled by a bolt connecting the two. The first adjustment seat 43 and the second adjustment seat 44 are detachably connected. By adjusting the position of the first adjustment seat 43 relative to the second adjustment seat 44, the position of the first clamping member 41 and the second clamping member 42 relative to the support 31 can be adjusted to be suitable for peeling tests of test pieces with different specifications and sizes and different peeling angles.
[0092] Optionally, a plurality of adjustment holes 441 are provided on the second adjustment seat 44, and a mounting hole 431 is provided on the first adjustment seat 43, the number of the mounting holes 431 is less than the number of the adjustment holes 441, and the position of the first adjustment seat 43 relative to the second adjustment seat 44 can be adjusted by connecting the mounting holes 431 with different corresponding positions of the adjustment holes 441. Optionally, the adjustment holes 441 are distributed in an array on the second adjustment seat 44.
[0093] Optionally, the adjustment hole 441 is set as a waist-shaped hole, and the installation hole 431 is set as a circular hole. Through the cooperation between the adjustment hole 441 and the installation hole 431, the position of the first adjustment seat 43 relative to the second adjustment seat 44 can be fine-tuned to ensure the fixing quality of the test piece.
[0094] The above description is that the connecting seat 12 is connected to the adjustment mechanism 20 and the first supporting mechanism 30. In another embodiment of the utility model, the second clamping member 42 can also be connected to the mounting plate 123 of the connecting seat 12, and the first clamping member 41 and the second clamping member 42 are controlled by bolts to control the spacing, thereby achieving the fixing effect on the test piece. The adjustment mechanism 20 and the first supporting mechanism 30 are independently arranged on one side of the second supporting mechanism 40, and the adjustment mechanism 20 can be connected to the adjustment component to adjust the position of the first supporting mechanism 30 relative to the second supporting mechanism 40.
[0095] In one embodiment of the present invention, as shown in the attached Figure 1As shown, the measuring mechanism 50 also includes a displacement measuring member 51, which is used to measure the relative displacement between the first supporting mechanism 30 and the second supporting mechanism 40. More specifically, the displacement measuring member 51 is used to measure the distance that the connecting seat 12 moves upward when driven by the screw rod 13.
[0096] In one example, as shown in the attached Figure 1 As shown, the displacement measuring member 51 includes a base rail 511 and a slide 512 slidably mounted on the base rail 511. The slide 512 is connected to the mounting plate 123. When the mounting plate 123 moves along the up and down directions with the transmission base 121, the slide 512 moves synchronously with the mounting plate 123. By measuring the upward displacement of the slide 512, the peeling displacement of the test piece can be obtained. By recording the peeling force of the test piece through a force sensor, the peeling force of the test piece can be obtained.
[0097] Optionally, the displacement measuring element 51 may be a linear sensor.
[0098] In one embodiment of the present invention, as shown in the attached Figure 1 As shown, the main body also includes a base 60, and the peeling mechanism 10, the adjusting mechanism 20, the first carrying mechanism 30, the second carrying mechanism 40 and the measuring mechanism 50 are directly or indirectly installed on the base 60, so as to integrate the peeling mechanism 10, the adjusting mechanism 20, the first carrying mechanism 30, the second carrying mechanism 40 and the measuring mechanism 50 on the base 60, which is convenient for the transportation of the main body, with higher integration and concentrated functions.
[0099] In one example, as shown in the attached Figure 7 As shown, the base 60 includes a first support platform 61 and a second support platform 62. The first support platform 61 is used to install the peeling mechanism 10, the second supporting mechanism 40 and the displacement measuring device 51. The displacement measuring device 51 is located on one side of the peeling mechanism 10. The second support platform 62 is used to contact the peeling mechanism 10 and the displacement measuring device 51 to improve the stability and structural reliability of the peeling mechanism 10 and the measuring mechanism 50.
[0100] In one example, the first support platform 61 and the second support platform 62 are vertically connected. To ensure the connection strength of the first support platform 61 and the second support platform 62, the first support platform 61 and the second support platform 62 are connected by a reinforcement member 63. The reinforcement member 63 can be a wedge plate or a triangular plate.
[0101] In one example, the first support platform 61 and the second support platform 62 are vertically arranged and integrally formed.
[0102] In one example, a mounting seat 64 is provided on the first support platform 61 , and the base 11 of the stripping mechanism 10 is mounted on the mounting seat 64 so that an appropriate distance is maintained between the stripping mechanism 10 and the displacement measuring member 51 , thereby facilitating measurement of the displacement data of the connecting seat 12 by the displacement measuring member 51 .
[0103] In one example, a plurality of positioning holes 611 are provided on the first support platform 61, and the positioning holes 611 cooperate with the adjustment holes 441 on the second adjustment seat 44 to install the second adjustment seat 44 on the first support platform 61. Optionally, the positioning holes 611 are set as screw holes, and the second adjustment seat 44 is detachably installed on the first support platform 61 by screw connection, which is simple and convenient to install.
[0104] In one example, the bottom of the first support platform 61 is provided with a support foot 612, which is conducive to reducing the contact area between the first support platform 61 and the workbench for placing the main body, so as to facilitate transportation. Optionally, the support foot 612 is set to four or six to play a good supporting role, ensure the stability of the main body placement, and ensure the accuracy of the test.
[0105] In one embodiment of the present invention, as shown in the attached Figure 8 As shown, the peeling test device for a wearable flexible electronic device proposed in the utility model also includes a control unit 71 and an interaction unit 72. The interaction unit 72 is communicatively connected to the control unit 71, and the control unit 71 is communicatively connected to at least one of the peeling mechanism 10, the adjustment mechanism 20 and the measuring mechanism 50. The operator can input relevant test data, such as the peeling angle, through the interaction unit 72 to achieve automatic control through the control unit 71.
[0106] In one example, the control unit 71 is in communication connection with the driving member 14 of the peeling mechanism 10 , and the control unit 71 is used to send instructions to the driving member 14 to enable the driving member 14 to work and drive the screw rod 13 to rotate around its own axis.
[0107] In one example, the control unit 71 is communicatively connected to the driving source of the movable part 22 of the adjustment mechanism 20, and the control unit 71 is used to send instructions to the driving source of the movable part 22 to make the movable part 22 rotate around its own axis relative to the support part 21, so as to drive the first supporting mechanism 30 to rotate to the peeling angle.
[0108] In one embodiment of the present invention, the peeling test device for a wearable flexible electronic device proposed in the present invention also includes an acquisition unit 73 and a display unit 74 that are communicatively connected to a control unit 71. The control unit 71 is communicatively connected to a measuring mechanism 50 through the acquisition unit 73. More specifically, the control unit 71 is communicatively connected to a force sensor and a displacement measuring member 51 through an acquisition unit 72. The force sensor is used to measure the peeling force of the test piece and send the peeling force data to the acquisition unit 73. The displacement measuring member 51 is used to measure the relative displacement data between the first supporting mechanism 30 and the second supporting mechanism 40 and send the displacement data to the acquisition unit 73. The acquisition unit 73 sends the collected peeling force data and displacement data to the control unit 71 and displays the peeling force data curve and the displacement data curve through the display unit 74.
[0109] Attached Fig. 9 It is a curve diagram of the displacement data and the peeling force data of an embodiment of the utility model, wherein L1 is the displacement data and the peeling force data curve of the test piece when the peeling angle is 45°, L2 is the displacement data and the peeling force data curve of the test piece when the peeling angle is 90°, and L3 is the displacement data and the peeling force data curve of the test piece when the peeling angle is 135°.
[0110] As attached Fig. 9 As shown, in a single peeling test, the peeling force first increases rapidly, and after increasing to a certain extent, enters a plateau period with small changes and fluctuations. At this time, the test piece begins to be peeled off. After the plateau period ends, the peeling force gradually decreases until the test piece is completely peeled off.
[0111] Combined with the L1 curve, when the peeling angle is 45°, the peeling force data value in the plateau period is 8.2N, and the displacement data value is 36mm. Combined with the L2 curve, when the peeling angle is 90°, the peeling force data value in the plateau period is 3.7N, and the displacement data value is 36mm. Combined with the L3 curve, when the peeling angle is 135°, the peeling force data value in the plateau period is 2.5N, and the displacement data value is 36mm.
[0112] It can be concluded from the above data that when the peeling angle is 45°, the required peeling force is the largest. Therefore, when the peeling angle is 45°, the peeling strength of the test piece is the largest. After various tests, when the peeling angle is smaller, the peeling strength of the test piece is larger.
[0113] Based on the above-mentioned peeling test device for wearable flexible electronic devices, the present invention also proposes a peeling test method for wearable flexible electronic devices, which is applied to the above-mentioned peeling test device and specifically includes the following steps:
[0114] S1 . Connect the test piece to the first supporting mechanism 30 , and make the test piece have a free end that is not connected to the first supporting mechanism 30 .
[0115] More specifically, the part to be tested of the test piece is pasted on the support 31, or a first test piece is first pasted on the support 31, and then the part to be tested of the second test piece is pasted on the first test piece, so as to test the peel strength between the two test pieces, or a base material is first set on the support 31 to simulate the surface of human skin, and then the test piece is pasted on the base material. In the above three test situations, the test piece includes a free end that is not connected to the support 31, and the free end is used to be fixedly connected to the second supporting mechanism 40;
[0116] Furthermore, the test piece on the support platform 31 can be leveled by a roller so that the test piece and the support platform 31 are evenly fitted, thereby ensuring that the measurement result is accurate and reliable.
[0117] S2, setting a peeling angle, and adjusting the angle of the first supporting mechanism 30 relative to the second supporting mechanism 40 by means of the adjusting mechanism 20.
[0118] In one example, the operator manually rotates the movable part 22 so that the movable part 22 rotates relative to the support part 21 until the support platform 31 is rotated to the desired testing angle. The operator inserts a clamp into the limit hole 321 of the limit part 32 and abuts the end of the clamp against the side of the support part 21 or the dial 23 to fix the movable part 22. At this time, the angle adjustment is completed.
[0119] In one example, the operator inputs a preset peeling angle through the interactive unit 72, and the control unit 71 sends a command to the driving source controlling the movable part 22, so that the movable part 22 automatically rotates relative to the support part 21 until the support platform 31 is rotated to the preset peeling angle. The operator inserts a clamp into the limiting hole 321 of the limiting part 32, and abuts the end of the clamp against the side of the support part 21 or the dial 23 to fix the movable part 22. At this time, the angle adjustment is completed.
[0120] S3, adjusting the position of the second supporting mechanism 40 relative to the first supporting mechanism 30, and connecting the free end of the to-be-tested piece to the second supporting mechanism 40.
[0121] In one example, the position of the first adjustment seat 43 relative to the second adjustment seat 44 is adjusted so that the positions of the first clamp 41 and the second clamp 42 correspond to the position of the support platform 31 , so as to connect the test piece to the second supporting mechanism 40 .
[0122] The connecting bolts between the first clamping member 41 and the second clamping member 42 are adjusted to increase the distance between the first clamping member 41 and the second clamping member 42, and the free end of the test piece is clamped between the first clamping member 41 and the second clamping member 42. The bolts are then tightened to reduce the distance between the first clamping member 41 and the second clamping member 42 until the test piece does not fall out from between the first clamping member 41 and the second clamping member 42.
[0123] S4. The relative positions of the first carrying mechanism 30 and the second carrying mechanism 40 are adjusted by the peeling mechanism 10 to increase the distance between the first carrying mechanism 30 and the second carrying mechanism 40 until the test piece is separated from the first carrying mechanism 30 .
[0124] In one example, the control unit 71 sends a command to the driving member 14, and the driving member 14 drives the screw 13 to rotate, so that the connecting seat 12 moves upward, and the distance between the first bearing mechanism 30 and the second bearing mechanism 40 increases until the test piece is completely separated from the first bearing mechanism 30. The control unit 71 sends a command to the driving member 14, and the driving member 14 stops driving the screw 13. S5. The measuring mechanism 50 measures the peeling force value and displacement value of the test piece.
[0125] In one example, the measuring mechanism 50 sends the peeling force data measured by the force sensor and the displacement data measured by the displacement measuring member 51 to the acquisition unit 73, and sends the data to the control unit 71 through the acquisition unit 73, and generates the following display on the display unit 74: Fig. 9 The data graph shown is to facilitate the operator to analyze the relevant data and judge and study the peel strength of the test piece.
[0126] The above S1 to S5 are merely steps to illustrate a possible peeling test method, and do not mean that the above steps must be performed in the order of S1 to S5. Those skilled in the art may change the order of the relevant steps according to actual needs.
[0127] The peeling test method for wearable flexible electronic devices of the utility model has simple steps and is easy to operate. It can test the peeling force of test pieces of different specifications and sizes, and then test the peeling strength of the test pieces, and the test results are accurate.
[0128] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
