[0002] The main functions of the protective film on the outer surface of the copper alloy composite plate include the following: Anti-corrosion protection: The protective film can prevent the surface of the copper alloy plate from direct contact with external corrosive substances, thereby avoiding or slowing down the corrosion process of the copper alloy plate; Anti-pollution: The protective film can prevent dust, oil, fingerprints and other pollutants from adhering to the surface of the copper alloy plate, keeping the plate clean and beautiful; Anti-scratch: During transportation, storage and installation, the protective film can prevent the surface of the copper alloy plate from mechanical damage or scratches, and protect its surface finish and integrity; Maintain gloss: The protective film helps to maintain the original gloss and color of the copper alloy plate, and prevents its surface from losing gloss due to oxidation or other reasons; Extend service life: By providing comprehensive protection, the protective film helps to extend the service life of the copper alloy composite plate and reduce the frequency of maintenance and replacement; In short, the protective film on the outer surface of the copper alloy composite plate is an indispensable part of its production, transportation, storage and use, and plays a vital role in maintaining the quality and performance of the product; Therefore, after the production of the copper alloy composite plate is completed, it is necessary to conduct a peeling test on the protective film adhered to its outer surface to ensure the performance of the protective film, and then determine the protective quality of the protective film on the copper alloy composite plate.

The peeling detection operation of the protective film at different positions can be performed without frequently changing the position of the copper alloy composite plate, thereby reducing the test burden and improving the detection efficiency.

[0017] 3. The present invention realizes the scribing operation of the peeling detection area by moving the clamping mechanism up and down on the protective film of the copper alloy composite plate, and can leave scratches on the protective film of the copper alloy composite plate, so as to facilitate the peeling of the protective film in the detection area during the peeling detection, and avoid the excessive lateral adhesion force between the protective films, which leads to the need for a larger pulling force to peel the protective film in the detection area, affecting the accuracy of the 180-degree peeling detection of the protective film on the outer surface of the copper alloy composite plate, thereby making the data obtained from the detection more convincing.

Two scratching knives 905 are provided, and the two scratching knives 905 are arranged at the edge of the side of the clamping slider 904 that contacts the protective film. An electric telescopic rod 906 is fixedly connected to the side of the clamping slider 904 away from the scratching knife 905, and a clamping block 907 is fixedly connected to the end of the electric telescopic rod 906. The clamping slider 904 is set to an inverted "L" shape, and the vertical side and the horizontal side of the inverted "L"-shaped clamping slider 904 are split-type designs, and the vertical side and the horizontal side of the clamping slider 904 are connected through a tension sensor 909, and the tension sensor 909 is electrically connected to the testing machine 1.

[0024] When in use, the position of the clamping slider 904 and the clamping block 907 is adjusted according to the position for peeling detection as needed. At this time, the servo motor 902 is started to rotate the first screw 903, and then the clamping slider 904 slides along the outer surface of the fixed frame 901 to achieve the purpose of adjusting the position of the clamping slider 904 and the clamping block 907.

At this time, the electric telescopic rod 906 can be started to move the clamping block 907 toward the clamping slider 904, and the edge of the protective film in the detection area is clamped by the clamping slider 904 and the clamping block 907. At this time, the lifting motor is started to rotate the lifting screw 8, and then the displacement plate 6 is driven to move upward through the connecting plate 7.

The tension generated by peeling the protective film is detected by the tension sensor 909, and the detected data is sent to the testing machine 1. In this process, the scratcher 905 will leave scratches on the protective film of the copper alloy composite plate, realizing the scribing operation of the peeling detection area, which is convenient for peeling the protective film in the detection area during the peeling detection, and avoids the need for a larger tension to peel the protective film in the detection area due to excessive lateral adhesion between the protective films, thereby affecting the accuracy of the 180-degree peeling test of the protective film on the outer surface of the copper alloy composite plate, thereby making the test data more convincing.

An edge starting knife 1206 is fixedly connected between the cutters 1205. The edge starting mechanism 12 also includes a displacement seat 1201 slidably connected to the top of the testing machine 1. The second screw 1105 penetrates the displacement seat 1201 and is connected to the displacement seat 1201 by a thread. The thread spacing of the first screw 903 and the second screw 1105 is the same. Therefore, when the clamping slider 904 moves, the displacement seat 1201 and the clamping slider 904 move synchronously, at the same speed and in the same direction, so that the displacement seat 1201 is always directly below the clamping slider 904.

[0026] In the process of changing the position of the clamping slider 904 and the clamping block 907, the rotation of the first screw 903 will drive the first worm gear 1101 to rotate, and then drive the first worm gear 1103 to rotate through the transmission shaft 1102, so that the second worm gear 1104 drives the second screw 1105 to rotate, and the rotation of the second screw 1105 will cause the displacement seat 1201 to slide along the top of the testing machine 1, so that the position of the clamping slider 904 and the clamping block 907 always corresponds to the position of the displacement seat 1201, so as to facilitate the peeling detection operation of the protective film on the outer surface of the copper alloy composite plate at different positions, and different positions of the copper alloy composite plate can be performed without frequently changing the position of the copper alloy composite plate. The peeling detection operation of the protective film in the position reduces the test burden and improves the detection efficiency, and the clamping slider 904 and the clamping block 907 will continue to move downward until the clamping slider 904 and the clamping block 907 reach the edge of the protective film peeling detection area and contact with the top of the lifting plate 1204. At this time, the cutter 1205 is located on both sides of the clamping slider 904 and fits with both sides of the clamping slider 904, and the edge of the protective film in the peeling detection area is located between the clamping slider 904 and the clamping block 907. In addition, when the clamping slider 904 and the clamping block 907 move up and down, the first worm gear 1101 will move up and down along the outer surface of the transmission shaft 1102.

[0028] After the copper alloy composite plate is clamped in the clamping mechanism 10, the edge knife 1206 is now facing the bonding position of the copper alloy composite plate and the protective film, and when the pinching slider 904 and the clamping block 907 slide downward and contact and attract each other with the connecting column 1303, the pinching slider 904 and the clamping block 907 continue to slide downward, which will push the hydraulic plate 1302 to slide downward along the inner surface of the hydraulic warehouse 1301 through the connecting column 1303, so that the liquid in the hydraulic warehouse 1301 enters the slide groove 1202 through the connecting groove 1304, so that the slide column 1203 pushes the lifting plate 1204 to move upward under the squeezing effect of the liquid, and then the edge knife 1206 enters the bonding position of the copper alloy composite plate and the protective film, and performs edge cutting on the protective film pasted on the outer surface of the copper alloy composite plate. When the edge raising knife 1206 raises the edge of the protective film attached to the outer surface of the copper alloy composite plate, the cutter 1205 will cut off the protective film in the test area that needs to be peeled off and the protective film outside the test area in the detection area, so as to avoid that the protective film attached to the outer surface of the copper alloy composite plate is raised by the edge raising knife 1206 during the edge raising operation, and the protective film raised by the edge raising knife 1206 and the cutter 1205 will enter the guide groove 1207, and rotate and move upward under the guidance of the guide groove 1207 and the guidance of the protrusion, so as to facilitate the raised protective film to enter the clamping slider 904 and the clamping block 907 through the inclined parts of the clamping slider 904 and the clamping block 907, so as to facilitate the clamping slider 904 and the clamping block 907 to clamp the protective film; When the clamping slider 904 and the clamping block 907 clamp the edge of the protective film upward to perform a peeling detection test, the upward movement of the clamping block 907 will cause the push-pull column 908 to move upward, and the connecting column 1303 will be pulled upward by the magnetic force, thereby driving the hydraulic plate 1302 to move upward, so that the liquid in the slide groove 1202 flows back to the hydraulic warehouse 1301 through the connecting groove 1304, and then the lifting plate 1204 falls on the top of the displacement seat 1201 again.

[0029] The specific working principle of the present invention is as follows: When in use, first place the bottom middle of the copper alloy composite plate to be tested on the top of the fixing seat 1001. At this time, the copper alloy composite plate is located between the clamping plate 1002 and the clamping frame 1004. At this time, the clamping screw 1003 can be rotated to move the clamping plate 1002 toward the clamping frame 1004. The copper alloy composite plate is clamped and fixed by the clamping plate 1002 and the clamping frame 1004. At this time, the edge cutter 1206 is facing the bonding position of the copper alloy composite plate and the protective film; The positions of the clamping slider 904 and the clamping block 907 are adjusted according to the position for peeling detection as needed. At this time, the servo motor 902 is started to rotate the first screw 903, and then the clamping slider 904 slides along the outer surface of the fixed frame 901, so as to achieve the purpose of adjusting the positions of the clamping slider 904 and the clamping block 907. In the process of changing the positions of the clamping slider 904 and the clamping block 907, the rotation of the first screw 903 will drive the first worm gear 1101 to rotate, and then drive the first worm gear 1103 to rotate through the transmission shaft 1102, so that the second worm gear 1104 drives the second screw 1105 to rotate, and the rotation of the second screw 1105 will cause the displacement seat 1201 to move along the top of the testing machine 1 The parts slide, so that the positions of the pinching slider 904 and the clamping block 907 always correspond to the position of the displacement seat 1201, and the peeling detection operation of the protective film at different positions can be performed without frequently changing the position of the copper alloy composite plate, which reduces the test burden and improves the detection efficiency. Then, the lifting motor can be started to rotate the lifting screw 8, and then the displacement plate 6 is driven to move downward through the connecting plate 7. The downward movement of the displacement plate 6 will drive the pinching slider 904 and the clamping block 907 to slide downward through the fixing frame 901. When the pinching slider 904 contacts the protective film of the copper alloy composite plate, the scratching knife 905 will leave scratches on the protective film of the copper alloy composite plate without contacting the copper alloy composite plate. When the clamping slider 904 and the clamping block 907 slide downward and contact and attract the connecting column 1303, the clamping slider 904 and the clamping block 907 continue to slide downward, and will push the hydraulic plate 1302 to slide downward along the inner surface of the hydraulic warehouse 1301 through the connecting column 1303, so that the liquid in the hydraulic warehouse 1301 enters the slide groove 1202 through the connecting groove 1304, so that the slide column 1203 pushes the lifting plate 1204 to move upward under the squeezing effect of the liquid, and then the edge knife 1206 enters the bonding position between the copper alloy composite plate and the protective film, and performs the edge operation on the protective film pasted on the outer surface of the copper alloy composite plate. When the edge knife 1206 performs the edge operation on the protective film pasted on the outer surface of the copper alloy composite plate, the cutter 1205 will cut off the protective film in the detection area that needs to be peeled off. The protective film and the protective film outside the test area are prevented from being edged during the edge raising operation. The protective film pasted on the outer surface of the copper alloy composite plate is edged by the edge raising knife 1206, and the protective film edged by the edge raising knife 1206 and the cutting knife 1205 will enter the guide groove 1207, and rotate and move upward under the guidance of the guide groove 1207 and the guidance of the protrusion, so that the edged protective film is convenient to enter the clamping slider 904 and the clamping block 907 through the inclined part of the clamping slider 904 and the clamping block 907, so that the clamping slider 904 and the clamping block 907 can clamp the protective film, so as to facilitate the peeling detection operation of the protective film on the outer surface of the copper alloy composite plate at different positions, and the peeling detection operation of the protective film at different positions can be performed without frequently changing the position of the copper alloy composite plate, which reduces the test burden and improves the detection efficiency; The clamping slider 904 and the clamping block 907 will continue to move downward until they reach the edge of the protective film peeling detection area and contact the top of the lifting plate 1204. At this time, the cutter 1205 is located on both sides of the clamping slider 904 and fits with both sides of the clamping slider 904, and the edge of the protective film in the peeling detection area is located between the clamping slider 904 and the clamping block 907. At this time, the electric telescopic rod 906 can be started to make the clamping block 907 move toward the clamping slider 904, and the edge of the protective film in the detection area can be clamped by the clamping slider 904 and the clamping block 907. At this time, the lifting motor is started to rotate the lifting screw 8, and then the displacement plate 6 is driven to move upward through the connecting plate 7, so that the protective film is peeled off 180 degrees upward by the clamping slider 904 and the clamping block 907 (it should be noted that when peeling starts, the cutter 1205 is located on both sides of the clamping slider 904 and fits with both sides of the clamping slider 904, so that the protective film outside the peeling test area can be prevented from being peeled off as the protective film in the test area is peeled off). The tension generated by peeling the protective film is detected by the tension sensor 909, and the detected data is sent to the testing machine 1 , and in the process of the clamping slider 904 and the clamping block 907 moving up and down, the scratching knife 905 will leave scratches on the protective film of the copper alloy composite plate, realizing the scribing operation of the peeling detection area, facilitating the peeling of the protective film in the detection area during the peeling detection, avoiding the need for a larger pulling force to peel the protective film in the detection area due to excessive lateral adhesion between the protective films, affecting the accuracy of the 180-degree peeling detection of the protective film on the outer surface of the copper alloy composite plate, thereby making the data obtained by the detection more convincing, and in the process of peeling, the test machine 1 records the peeling length through the scale 14 set on the outer surface of the column 4 and the height of the displacement plate 6 on the column 4, and the data detected by the test machine 1 is sent to the computer through the data line, and the computer analyzes the detection data to determine the performance of the protective film; When the clamping slider 904 and the clamping block 907 clamp the edge of the protective film upward to perform a peeling test, the upward movement of the clamping block 907 will cause the push-pull column 908 to move upward, and the connecting column 1303 will be pulled upward by the magnetic force, thereby driving the hydraulic plate 1302 to move upward, so that the liquid in the slide groove 1202 flows back to the hydraulic warehouse 1301 through the connecting groove 1304, and then the lifting plate 1204 falls back on the top of the displacement seat 1201, so as to facilitate the next peeling test operation.
