It is also the main component of the negative electrode of lithium batteries. During the production process of copper foil, it is necessary to test the peeling resistance of copper foil. The peeling force of copper foil is very important for the electronics industry and circuit board manufacturing because it directly affects the reliability and service life of the circuit board.

[0003] At present, when performing peeling test on copper foil, most of them adopt vertical peeling test method, that is, the peeling angle of copper foil is 90°. However, during the peeling process, the peeling angle between copper foil and substrate is prone to change, so that copper foil cannot always maintain a vertical state during the test, which affects the accuracy of the peeling test result of the entire test device.

[0019] Beneficial effects of the present invention:

[0020] The present invention provides an electrolytic copper foil peeling strength testing device. Through the provided positioning assembly, the third rack at the bottom of the substrate will mesh with the fifth gear in the cavity during the process of inserting the substrate into the assembly slot, so that the fifth gear rotates. During the rotation of the fifth gear, the third rotating column and the fourth gear can be driven to rotate together. The fourth gear can drive the sixth gear to rotate in the same direction through the transmission of the changing gear, so that the sixth gear rotates counterclockwise, and the sixth gear and the fourth rack mesh with each other.

[0021] The present invention provides an electrolytic copper foil peeling strength testing device. Through the provided clamping assembly, a staff member passes one end of a copper foil body around a positioning roller and a squeezing roller and rotates a rotating block. The rotating block can drive a second threaded screw to rotate. During the rotation of the second threaded screw, the squeezing roller and the clamping plate can be driven to move together. The copper foil body can be fixed once through the clamping plate and the rubber pad. At the same time, the copper foil body wrapped around the outer walls of the squeezing roller and the positioning roller will also be squeezed and locked by them to achieve secondary fixation. The copper foil body will deform and clamp into an arc groove during the squeezing process, thereby further improving the locking effect of the squeezing roller and the positioning roller on the copper foil body, and ensuring that the copper foil body will not fall off from the clamping box during subsequent peeling detection.

[0022] The present invention provides an electrolytic copper foil peeling strength testing device. Through the provided synchronization component, a staff starts a motor, drives a clamping component and a tension sensor to rise through a first threaded sleeve to perform peeling detection on a copper foil body. In the process of the first threaded sleeve and a fixed frame rising, the first rack can be driven to rise as a whole through a horizontal column, and the first gear can be driven to rotate in the process of the first rack rising. When the first gear rotates, the second bevel gear can be driven to rotate together, and the second bevel gear is meshed with the first bevel gear, so as to drive the second rotating column to rotate. In the process of the second rotating column rotating, the third gear can be driven to rotate, and the third gear is meshed with the fourth gear, so as to drive the second rack to move horizontally. The specifications of the third gear and the fourth gear, the first bevel gear and the second bevel gear are the same, so as to ensure that the vertical rising distance of the first threaded sleeve is the same as the horizontal moving distance of the fixed seat, that is, the peeling rising height of the copper foil body is the same as the length of the horizontal displacement, so that the pulled copper foil body and the copper foil body bonded to the substrate are always kept vertical, further improving the accuracy of the detection result, and avoiding the situation that the angle change of the copper foil body during the peeling process causes a large error in the result.

[0023] The present invention provides an electrolytic copper foil peeling strength testing device. When the copper foil body rises to a certain height during peeling detection, the extrusion block on one side of the movable plate will be squeezed with the U-shaped rod, so that the extrusion block can drive the movable plate to move in the direction close to the vertical plate until the movable plate presses the copper foil body against the outer wall of one side of the vertical plate. At this time, the auxiliary clamping of the movable plate expands the clamping area of ​​the copper foil body, which can effectively reduce the occurrence of the copper foil body being peeled off too long and breaking.

The specifications of the third gear 45 and the fourth gear 54, the first bevel gear 34 and the second bevel gear 35 are the same, thereby ensuring that the vertical rising distance of the first threaded sleeve 6 is the same as the horizontal moving distance of the fixing seat 10, that is, ensuring that the peeling and rising height of the copper foil body 11 is the same as the length of the horizontal displacement.The pulled copper foil body 11 is always kept perpendicular to the copper foil body 11 bonded to the substrate 12, which further improves the accuracy of the detection result and avoids the copper foil body 11 from changing its angle during the peeling process, which leads to a large error in the result. When the copper foil body 11 rises to a certain height, the extrusion block 30 on one side of the movable plate 25 will be squeezed with the U-shaped rod 9, so that the extrusion block 30 can drive the movable plate 25 to move toward the direction close to the vertical plate 24 until the movable plate 25 presses the copper foil body 11 against the outer wall of one side of the vertical plate 24. At this time, the auxiliary clamping of the movable plate 25 expands the clamping area of ​​the copper foil body 11, which can effectively reduce the occurrence of the copper foil body 11 being peeled too long and broken.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
