Description

Technical Field

[0001] The present invention belongs to the technical field of composite plate detection and peeling, and particularly relates to a peeling test device for detecting copper alloy composite plates. Background Art

[0002] The main functions of the protective film on the outer surface of copper alloy composite plates include the following points: Anti-corrosion protection: The protective film can prevent the surface of the copper alloy plate from coming into 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 block the attachment of pollutants such as dust, oil stains, and fingerprints on the surface of the copper alloy plate, keeping the plate surface clean and beautiful; Anti-scratching: During transportation, storage, and installation, the protective film can prevent the surface of the copper alloy plate from being mechanically damaged or scratched, protecting its surface finish and integrity; Maintaining luster: The protective film helps to maintain the original luster and color of the copper alloy plate, preventing its surface from losing luster due to oxidation or other reasons; Extending service life: By providing comprehensive protection, the protective film helps to extend the service life of copper alloy composite plates and reduce the frequency of maintenance and replacement; In short, the protective film on the outer surface of copper alloy composite plates is an indispensable part during their production, transportation, storage, and use, and plays a crucial role in maintaining the quality and performance of the products; Therefore, after the production of copper alloy composite plates 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 protection quality of the protective film for copper alloy composite plates.

[0003] Currently, when detecting the peeling performance of the protective film on the outer surface of copper alloy composite plates, it is necessary to perform peeling test operations on the protective films at various positions on the outer surface of the copper alloy composite plates, and divide corresponding test areas. In addition, it is also necessary to manually perform the edge-lifting operation of the protective film at the bottom of each test area of the copper alloy composite plate, and manually clamp the edge-lifted protective film on the peeling fixture before the peeling detection operation can be carried out. In addition, since the front and rear positions of the peeling fixture of the existing peeling testing machine cannot be adjusted, when detecting the protective films at various positions on the outer surface of the copper alloy composite plate, it is necessary to frequently change the position of the copper alloy composite plate on the fixture, which increases the labor burden and affects the detection efficiency. Based on this, a peeling test device for detecting copper alloy composite plates is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a reasonably designed peeling test device for detecting copper alloy composite plates to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A peeling test device for detecting copper alloy composite plates, including a testing machine, a column, a folding curtain, a displacement plate, a connecting plate, and a lifting screw, further includes:

[0007] A pinching mechanism fixedly connected to the displacement plate for pinching the protective film. The pinching mechanism includes a pinching slider.

[0014] As a further optimized solution of the present invention, the distance between the two clamping frames is greater than the width of the pinching slider and the distance between the two cutting knives.

[0015] As a further optimized solution of the present invention, the edge-lifting mechanism further includes a displacement seat slidably connected to the top of the testing machine. A chute is provided in the displacement seat. A sliding column is hermetically slidably connected in the chute. The sliding column is fixedly connected to the bottom of the lifting plate. A guiding groove communicating with the side wall of the edge-lifting knife is provided on the top of the lifting plate.

[0016] As a further optimized solution of the present invention, the lifting mechanism includes a hydraulic chamber fixedly connected to the top of the displacement seat. A hydraulic plate is hermetically and slidably connected inside the hydraulic chamber. A connecting column is fixedly connected to the top of the hydraulic plate. A communication groove communicating with the inside of the hydraulic chamber is formed in the displacement seat.

[0017] As a further optimized solution of the present invention, the communication groove communicates with the inside of the sliding groove. The top of the connecting column has magnetism, the bottom of the push-pull column has magnetism, and the magnetism of the push-pull column is opposite to that of the connecting column.

[0018] As a further optimized solution of the present invention, the transmission mechanism includes a first worm wheel rotatably connected inside the fixed frame. One end of the first screw rod away from the servo motor is in the form of a worm. The part of the first worm wheel and the first screw rod in the form of a worm are meshed.

The bottom end of the lifting screw rod is rotatably connected to the testing machine.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. Through the combined use of the pinching mechanism, the edge-lifting mechanism and the lifting mechanism of the present invention, when the pinching mechanism moves downward to pinch the edge position of the protective film in the detection area, when the pinching mechanism moves downward and contacts the lifting mechanism, the continuous downward movement of the pinching mechanism will cause the edge-lifting mechanism to work upward to perform an edge-lifting operation on the edge part of the protective film in the detection area. And the edge-lifted protective film will be guided upward at the edge part of the edge-lifted protective film under the action of the guiding groove and the inclined protrusions until the pinching mechanism contacts the edge-lifting mechanism. At this time, the edge-lifted protective film will enter between the pinching slider and the clamping block, which is convenient for the pinching mechanism to pinch the protective film, eliminating the need for manual edge-lifting and improving the detection efficiency.

[0022] 2. By the combined use of the pinching mechanism, the transmission mechanism, and the edge-lifting mechanism, when performing peeling detection at different positions on the protective film on the outer surface of the copper alloy composite plate, the pinching mechanism is activated to change the positions of the pinching slider and the pinch block, and then the position of the edge-lifting mechanism is changed through the transmission mechanism, so that the positions of the pinching mechanism and the edge-lifting mechanism always correspond. Thus, it is convenient to perform peeling detection operations at different positions on the protective film on the outer surface of the copper alloy composite plate. Without frequently changing the position of the copper alloy composite plate, the peeling detection operation of the protective film at different positions can be carried out, reducing the test burden and improving the detection efficiency.

[0023] 3. By the up-and-down movement of the pinching mechanism on the protective film of the copper alloy composite plate, the scribing operation of the peeling detection area is realized, and at the same time, scratches can be left on the protective film of the copper alloy composite plate, which is convenient for the peeling of the protective film in the detection area during peeling detection. It avoids the situation that due to the excessive lateral adhesion force between the protective films, a greater pulling force is required 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 persuasive.

Detailed implementation manners

[0038] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further explain the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application based on the above application content.

[0039] Example: As shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 13As shown in the figure, a peeling test device for detecting copper alloy composite plates includes a testing machine 1, a column 4, a folding curtain 5, a displacement plate 6, a connecting plate 7, and a lifting screw 8. An emergency stop button 2 and a lifting switch 3 are installed on the testing machine 1. The column 4 is fixedly connected to the top of the testing machine 1. A data line jack is installed on the side wall of the testing machine 1 for connecting to a computer through a data line. The data detected by the testing machine 1 is sent to the computer through the data line, and the computer analyzes the data and generates a corresponding line graph. The folding curtain 5 is installed inside the column 4. The displacement plate 6 is slidably connected to the column 4. The folding curtain 5 is used to prevent dust from entering the column 4 through the part where the displacement plate 6 is slidably connected to the column 4. A scale 14 is provided on one side of the column 4 where the displacement plate 6 is located, facilitating reading of the peeling distance. The connecting plate 7 is fixedly connected to the displacement plate 6. The lifting screw 8 passes through the connecting plate 7 and is threadedly connected to the connecting plate 7. The top end of the lifting screw 8 is rotatably connected to the column 4, and the bottom end of the lifting screw 8 is rotatably connected to the testing machine 1. A lifting motor is installed inside the testing machine 1, and the output end of the lifting motor is fixedly connected to the lifting screw 8 (the lifting motor is installed inside the testing machine 1 and is a prior art, not shown in the figure and not described in detail). It further includes: a clamping mechanism 10 fixedly connected to the top of the testing machine 1 for fixing the copper alloy composite plate. The clamping mechanism 10 includes a fixed seat 1001 fixedly connected to the top of the testing machine 1. A clamping plate 1002 is attached to the top of the fixed seat 1001. A clamping screw 1003 is rotatably connected to the side of the clamping plate 1002 away from the clamping surface. The clamping screw 1003 passes through the fixed seat 1001 and is threadedly connected to the fixed seat 1001. Two clamping brackets 1004 are fixedly connected to the outer surface of the fixed seat 1001. It further includes: a pinching mechanism 9 fixedly connected to the displacement plate 6 for pinching the protective film.

[0040] During use, first place the middle position at the bottom of the copper alloy composite plate to be detected on the top of the fixed seat 1001. At this time, the copper alloy composite plate is located between the clamping plate 1002 and the clamping brackets 1004, as Figure 13 shown (a in the figure is the copper alloy composite plate with a protective film pasted on it). Then, the clamping screw 1003 can be rotated to make the clamping plate 1002 move towards the clamping brackets 1004, and the copper alloy composite plate is clamped and fixed by the clamping plate 1002 and the clamping brackets 1004. Then, the lifting motor can be started to make the lifting screw 8 rotate, and then the displacement plate 6 is moved downward through the connecting plate 7, further driving the pinching mechanism 9 to move downward, so that the pinching mechanism 9 draws a line in the detection area of the copper alloy composite plate and pinches the edge part of the protective film in the detection area of the copper alloy composite plate. Then, the lifting motor is started to make the lifting screw 8 rotate, driving the displacement plate 6 to move upward through the connecting plate 7, and then the protective film on the outer surface of the copper alloy composite plate is pinched and peeled off by 180 degrees through the pinching mechanism 9.

[0041] As Figure 1 、 Figure 3 、Figure 4 , Figure 8 , Figure 9 , Figure 10 and Figure 13 As shown in Figure 4 , Figure 8 , Figure 9 , Figure 10 and Figure 13 , the pinching mechanism 9 includes a pinching slider 904. A cutter 905 is fixedly connected to the surface of the pinching slider 904 that contacts the protective film. There are two cutters 905, and the two cutters 905 are arranged at the edge of the surface of the pinching slider 904 that contacts the protective film. A telescopic electric rod 906 is fixedly connected to the surface of the pinching slider 904 away from the cutter 905. The end of the telescopic electric rod 906 is fixedly connected to a clamping block 907. The pinching slider 904 is arranged in an inverted "L" shape. The vertical side and the horizontal side of the inverted "L" shaped pinching slider 904 are of split design, and the vertical side and the horizontal side of the pinching slider 904 are connected by a tension sensor 909. The tension sensor 909 is electrically connected to the testing machine 1. The cutter 905 is only fixedly connected to the vertical side of the pinching slider 904. The bottoms of the adjacent surfaces of the clamping block 907 and the vertical side of the pinching slider 904 are both inclined. The adjacent surfaces of the clamping block 907 and the vertical side of the pinching slider 904 are both provided with anti-slip lines. The pinching mechanism 9 further includes a fixed frame 901 fixedly connected to the displacement plate 6. The pinching slider 904 fits with the fixed frame 901. A servo motor 902 is installed at the end of the fixed frame 901. The output end of the servo motor 902 is fixedly connected to a first screw rod 903. The first screw rod 903 passes through the pinching slider 904 and is threadedly connected to the pinching slider 904. The end of the first screw rod 903 is rotatably connected to the displacement plate 6. A push-pull column 908 is fixedly connected to the bottom of the clamping block 907.

[0042] During use, adjust the positions of the pinch slider 904 and the clamping block 907 according to the position where the peeling detection is required. At this time, start the servo motor 902 to rotate the first screw rod 903, so that the pinch slider 904 slides along the outer surface of the fixed frame 901, achieving the purpose of adjusting the positions of the pinch slider 904 and the clamping block 907. Then, start the lifting motor to rotate the lifting screw rod 8, and then drive the displacement plate 6 to move downward through the connecting plate 7 until the pinch slider 904 and the clamping block 907 reach the edge of the protective film peeling detection area, and the edge of the protective film within the peeling detection area is located between the pinch slider 904 and the clamping block 907. At this time, start the electric telescopic rod 906 to make the clamping block 907 move towards the pinch slider 904, and pinch the edge of the protective film within the detection area through the pinch slider 904 and the clamping block 907. At this time, start the lifting motor to rotate the lifting screw rod 8, and then drive the displacement plate 6 to move upward through the connecting plate 7, so as to peel the protective film 180 degrees upward through the pinch slider 904 and the clamping block 907. The pulling force generated by peeling the protective film is detected by the tensile force sensor 909, and the detected data is sent to the testing machine 1. And during this process, the cutting knife 905 will leave a scratch 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 within the detection area during peeling detection, and avoiding the need for a greater pulling force to peel the protective film within the detection area due to excessive lateral adhesion force between the protective films, which affects the accuracy of the 180-degree peeling detection of the protective film on the outer surface of the copper alloy composite plate, thus making the detected data more persuasive. And during the peeling process, the testing 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. The data detected by the testing machine 1 is sent to the computer through the data cable, and the computer analyzes the detected data to judge the performance of the protective film.

[0043] Such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown in the figure, the peeling test device further includes: a film edge lifting mechanism 12 connected to the clamping mechanism 9 through a transmission mechanism 11. The transmission mechanism 11 includes a first worm gear 1101 rotatably connected within a fixed frame 901. One end of a first screw rod 903 away from a servo motor 902 is configured in the form of a worm. The part of the first screw rod 903 configured in the form of a worm meshes with the first worm gear 1101. A transmission shaft 1102 is slidably connected within the first worm gear 1101. The outer surface of the transmission shaft 1102 and the inner surface of the first worm gear 1101 are both configured in a hexahedral shape and are in contact with each other. In addition to the function of transmitting power, the transmission shaft 1102 also has the function of limiting the position of the displacement plate 6 to ensure the stable up and down movement of the displacement plate 6. The top of the transmission shaft 1102 is rotatably connected to a column 4. The bottom of the transmission shaft 1102 is fixedly connected to a first worm 1103. The bottom of the first worm 1103 is rotatably connected to the top of a testing machine 1. A second screw rod 1105 is rotatably connected to the top of the testing machine 1. One end of the second screw rod 1105 is fixedly connected to a second worm gear 1104. The second worm gear 1104 meshes with the first worm 1103. The film edge lifting mechanism 12 includes a lifting plate 1204 disposed below a clamping slider 904. On both sides of the surface of the lifting plate 1204 in contact with the protective film, cutting knives 1205 are fixedly connected. The parts of the cutting knives 1205 in contact with the protective film and the tops thereof are both provided with cutting edges to facilitate cutting the protective film. The distance between two clamping frames 1004 is greater than the width of the clamping slider 904 and the distance between the two cutting knives 1205. A film edge lifting knife 1206 is fixedly connected between the cutting knives 1205. The film edge lifting mechanism 12 further includes a displacement seat 1201 slidably connected to the top of the testing machine 1. The second screw rod 1105 passes through the displacement seat 1201 and is threadedly connected to the displacement seat 1201. The thread pitch of the first screw rod 903 is the same as that of the second screw rod 1105. Therefore, when the clamping slider 904 moves, the displacement seat 1201 moves synchronously, at the same speed, and in the same direction as the clamping slider 904, so that the displacement seat 1201 is always directly below the clamping slider 904. A chute 1202 is formed within the displacement seat 1201. A sliding column 1203 is hermetically slidably connected within the chute 1202. The sliding column 1203 is fixedly connected to the bottom of the lifting plate 1204. A guiding groove 1207 communicating with the side wall of the film edge lifting knife 1206 is formed at the top of the lifting plate 1204. An inclined protrusion is fixedly connected to the lifting plate 1204 at a position on the side of the guiding groove 1207 away from the film edge lifting knife 1206 to facilitate the clamping slider 904 and the clamping block 907 to clamp the protective film lifted by the film edge lifting knife 1206. It should be noted that when the lifting plate 1204 lands on the top of the displacement seat 1201, at this time, both the cutting knives 1205 and the film edge lifting knife 1206 are located below the clamping frames 1004, and the cutting knives 1205 are located on both sides of the clamping slider 904.

[0044] During the process of changing the positions of the pinch slider 904 and the clamping block 907, the rotation of the first screw 903 will drive the rotation of the first worm gear 1101. Then, through the transmission shaft 1102, it will drive the rotation of the first worm 1103, causing the second worm gear 1104 to drive the rotation of the second screw 1105. The rotation of the second screw 1105 will cause the displacement seat 1201 to slide along the top of the testing machine 1. As a result, the positions of the pinch slider 904 and the clamping block 907 always correspond to the position of the displacement seat 1201. This facilitates the peeling detection operation of the protective film on the outer surface of the copper alloy composite plate at different positions. Without frequently changing the position of the copper alloy composite plate, the peeling detection operation of the protective film at different positions can be carried out, reducing the test burden and improving the detection efficiency. Then, the pinch slider 904 and the clamping block 907 will continue to move downward until the pinch slider 904 and the clamping block 907 reach the edge part of the protective film peeling detection area and simultaneously contact the top of the lifting plate 1204. At this time, the cutting knife 1205 is located on both sides of the pinch slider 904 and fits with both sides of the pinch slider 904, and the edge part of the protective film within the peeling detection area is located between the pinch slider 904 and the clamping block 907. In addition, when the pinch 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.

[0045] As Figure 5 , Figure 7 and Figure 12 shown, the peeling test device further includes a lifting mechanism 13 fixedly connected to the edge-lifting mechanism 12 for lifting the lifting plate 1204. The lifting mechanism 13 includes a hydraulic chamber 1301 fixedly connected to the top of the displacement seat 1201. A hydraulic plate 1302 is hermetically and slidably connected within the hydraulic chamber 1301. A connecting column 1303 is fixedly connected to the top of the hydraulic plate 1302. The connecting column 1303 penetrates through the hydraulic chamber 1301 and extends to the top of the hydraulic chamber 1301. The top of the connecting column 1303 has magnetism, and the bottom of the push-pull column 908 has magnetism. The magnetism of the push-pull column 908 is opposite to that of the connecting column 1303. The connecting column 1303 is arranged facing the push-pull column 908. A communication groove 1304 communicating with the inside of the hydraulic chamber 1301 is formed within the displacement seat 1201. The communication groove 1304 communicates with the inside of the sliding groove 1202. The hydraulic chamber 1301, the communication groove 1304, and the sliding groove 1202 are all filled with liquid.

[0046] After clamping the copper alloy composite plate within the clamping mechanism 10, at this time the edge-lifting knife 1206 is exactly opposite to the pasted part of the copper alloy composite plate and the protective film. When the pinching slider 904 and the clamping block 907 slide downward to contact and attract the connecting column 1303, the continuous downward sliding of the pinching slider 904 and the clamping block 907 will push the hydraulic plate 1302 to slide downward along the inner surface of the hydraulic chamber 1301 through the connecting column 1303, so that the liquid in the hydraulic chamber 1301 enters the chute 1202 through the communication groove 1304, and the sliding column 1203 pushes the lifting plate 1204 to move upward under the extrusion of the liquid, and then the edge-lifting knife 1206 enters the pasted part of the copper alloy composite plate and the protective film to perform an edge-lifting operation on the protective film pasted on the outer surface of the copper alloy composite plate. When the edge-lifting knife 1206 performs an edge-lifting operation on the protective film pasted on the outer surface of the copper alloy composite plate, the cutting knife 1205 will cut off the protective film in the area to be peeled and the protective film outside the test area within the detection area, so as to avoid all the protective films pasted on the outer surface of the copper alloy composite plate being edge-lifted by the edge-lifting knife 1206. The protective film on which the edge-lifting knife 1206 and the cutting knife 1205 perform edge-lifting will enter the guiding groove 1207, and will rotate and move upward under the guiding of the guiding groove 1207 and the guiding of the protrusion, so that the edge-lifted protective film can enter the pinching slider 904 and the clamping block 907 through the inclined part of the pinching slider 904 and the clamping block 907, thus facilitating the pinching slider 904 and the clamping block 907 to pinch the protective film;

[0047] When the pinching slider 904 and the clamping block 907 pinch the edge-lifted part of the protective film and perform a peeling detection test upward, the upward movement of the clamping block 907 will cause the push-pull column 908 to move upward, pull the connecting column 1303 to move upward by magnetic force, and then drive the hydraulic plate 1302 to move upward, so that the liquid in the chute 1202 flows back to the hydraulic chamber 1301 through the communication groove 1304, and then the lifting plate 1204 falls back on the top of the displacement seat 1201 again.

[0048] The specific working principle of the present invention is as follows:

[0049] When in use, first place the middle position at the bottom of the copper alloy composite plate to be detected on the top of the fixed seat 1001. At this time, the copper alloy composite plate is located between the clamping plate 1002 and the clamping frame 1004. Then, the clamping screw 1003 can be rotated to make the clamping plate 1002 move towards the clamping frame 1004, and the copper alloy composite plate is clamped and fixed by the clamping plate 1002 and the clamping frame 1004. At this time, the edge-lifting knife 1206 is exactly opposite to the pasted part of the copper alloy composite plate and the protective film;

[0050] Adjust the positions of the pinch slider 904 and the clamping block 907 according to the position where the peeling detection is required. At this time, start the servo motor 902 to rotate the first screw rod 903, so that the pinch slider 904 slides along the outer surface of the fixed frame 901, achieving the purpose of adjusting the positions of the pinch slider 904 and the clamping block 907. During the process of changing the positions of the pinch slider 904 and the clamping block 907, the rotation of the first screw rod 903 will drive the first worm gear 1101 to rotate, and then drive the first worm 1103 to rotate through the transmission shaft 1102, so that the second worm gear 1104 drives the second screw rod 1105 to rotate. The rotation of the second screw rod 1105 will cause the displacement seat 1201 to slide along the top of the testing machine 1, so that the positions of the pinch slider 904 and the clamping block 907 always correspond to the position of the displacement seat 1201. The peeling detection operation of the protective film at different positions can be carried out without frequently changing the position of the copper alloy composite plate, reducing the test burden and improving the detection efficiency. Then, start the lifting motor to rotate the lifting screw rod 8, and then drive the displacement plate 6 to move downward through the connecting plate 7. The downward movement of the displacement plate 6 will drive the pinch slider 904 and the clamping block 907 to slide downward through the fixed frame 901. When the pinch slider 904 contacts the protective film of the copper alloy composite plate, at this time, the cutting knife 905 will leave a scratch on the protective film of the copper alloy composite plate and will not contact the copper alloy composite plate;

[0051] When the clamping slider 904 and the clamping block 907 slide downward and come into contact with and attract the connecting column 1303, if the clamping slider 904 and the clamping block 907 continue to slide downward, they will push the hydraulic plate 1302 to slide downward along the inner surface of the hydraulic chamber 1301 through the connecting column 1303, causing the liquid in the hydraulic chamber 1301 to enter the chute 1202 through the communication groove 1304. Then, under the extrusion of the liquid, the sliding column 1203 will push the lifting plate 1204 upward, and further cause the edge lifting knife 1206 to enter the pasting part of the copper alloy composite plate and the protective film, performing an edge lifting operation on the protective film pasted on the outer surface of the copper alloy composite plate. When the edge lifting knife 1206 performs the edge lifting operation on the protective film pasted on the outer surface of the copper alloy composite plate, the cutting knife 1205 will cut off the protective film in the area to be subjected to the peeling test and the protective film outside the test area in the detection area, preventing all the protective film pasted on the outer surface of the copper alloy composite plate from being edge lifted by the edge lifting knife 1206 during the edge lifting operation. The protective film on which the edge lifting knife 1206 and the cutting knife 1205 perform the edge lifting will enter the guiding groove 1207, and rotate and move upward under the guiding of the guiding groove 1207 and the guiding of the protrusion, so that the edge lifted protective film can enter the clamping slider 904 and the clamping block 907 through the inclined part of the clamping slider 904 and the clamping block 907, facilitating the clamping slider 904 and the clamping block 907 to clamp the protective film, and thus facilitating the peeling detection operation of the protective film at different positions on the outer surface of the copper alloy composite plate. The peeling detection operation of the protective film at different positions can be carried out without frequently changing the position of the copper alloy composite plate, reducing the test burden and improving the detection efficiency;

[0052] Then 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 part of the protective film peeling detection area and simultaneously contact the top of the lifting plate 1204. At this time, the cutting knife 1205 is located on both sides of the clamping slider 904 and fits with both sides of the clamping slider 904, and the edge part of the protective film in the peeling detection area is located between the clamping slider 904 and the clamping block 907;

[0053] At this time, the electric telescopic rod 906 can be activated to move the clamping block 907 towards the clamping slider 904, and the edge part of the protective film within the detection area is clamped by the clamping slider 904 and the clamping block 907. At this time, the lifting motor is activated to rotate the lifting screw rod 8, and then the displacement plate 6 is driven upward by the connecting plate 7, so as to strip the protective film upward by 180 degrees through the clamping slider 904 and the clamping block 907 (it should be noted that at the beginning of stripping, since the cutting knife 1205 is located on both sides of the clamping slider 904 and is in contact with both sides of the clamping slider 904, it can avoid the protective film outside the stripping test area from being stripped along with the stripping of the protective film within the test area). The pulling force generated by stripping the protective film is detected by the pulling force sensor 909, and the detected data is sent to the testing machine 1. Moreover, during the up and down movement of the clamping slider 904 and the clamping block 907, the scoring knife 905 will leave scratches on the protective film of the copper alloy composite plate, realizing the scoring operation of the stripping detection area, facilitating the stripping of the protective film within the detection area during stripping detection, and avoiding the need for a greater pulling force to strip the protective film within the detection area due to excessive lateral adhesion force between the protective films, which affects the accuracy of the 180-degree stripping detection of the protective film on the outer surface of the copper alloy composite plate, thereby making the detected data more persuasive. And during the stripping process, the testing machine 1 records the stripping length through the scale 14 provided on the outer surface of the column 4 and the height of the displacement plate 6 on the column 4. The data detected by the testing machine 1 is sent to the computer through the data cable, and the computer analyzes the detection data to judge the performance of the protective film;

[0054] When the starting edge part of the protective film is clamped by the clamping slider 904 and the clamping block 907 and the upward stripping detection test is carried out, the upward movement of the clamping block 907 will cause the push-pull column 908 to move upward, and the magnetic connection column 1303 is pulled upward by the magnetic force, and then the hydraulic plate 1302 is driven upward, so that the liquid in the chute 1202 flows back into the hydraulic chamber 1301 through the communication groove 1304, and then the lifting plate 1204 falls back on the top of the displacement seat 1201 again, facilitating the next stripping test operation.

[0055] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
