Description

Technical Field

[0001] The present invention relates to the technical field of electroplating coating testing, in particular to an electroplating coating protective performance testing machine. Background Art

[0002] Electroplating is a surface treatment technology widely used in industrial manufacturing. It deposits a metal film on the surface of a metal or non-metallic substrate through electrolysis to achieve the purpose of enhancing aesthetics, corrosion protection, wear resistance, conductivity or other specific functions. With the advancement of technology and the increase in industrial demand, the quality control of the electroplating layer has become particularly important, especially its protective performance, which is directly related to the service life and reliability of the product. Therefore, the protective performance testing of the electroplating coating has become an indispensable part of ensuring product quality.

[0003] Nowadays, when testing the protective performance of the coating on the surface of a product, it is usually performed as an adhesion test of the coating on the surface of the product. During the operation, a handheld knife is used to manually draw a set of parallel cuts on the coating, and then another set of parallel cuts is drawn, and the other set of cuts is made perpendicular to the upper set of cuts, so that the two sets of cuts form a uniform grid. Then, a transparent tape is used to stick to the grid-shaped coating surface, and then the tape is quickly torn off. Then, the shedding of the grid-shaped coating on the surface of the product is observed, thereby completing the adhesion test of the coating on the surface of the product and thus completing the protective performance test of the coating. However, when the above method is used for tubular products, since the coating on the surface of the tubular product is an arc surface, it is easy for the handheld knife to draw two sets of parallel cuts on the coating, and the handheld knife is easy to be accidentally injured by the knife when cutting, which has low safety. In addition, it is difficult to grasp the spacing of the arc surface, which makes it difficult to cut a uniform grid. Summary of the Invention

[0030] See Figure 2 and Figure 3 As shown, the rotating mechanism includes a servo motor I 12 and a gear 13; the servo motor I 12 is installed on the front side of the lower part of the base 1; the gear 13 is connected to the output shaft of the servo motor I 12, and the gear 13 is engaged with the gear ring 3, so that the servo motor I 12 can drive the gear ring 3 to rotate through the gear 13.

[0031] See Figure 2 and Figure 3 As shown, the stabilizing mechanism includes an electric push rod II 14 and a conveying member 15; four electric push rods II 14 are installed at annular intervals on the upper rear part of the base 1; the conveying member 15 is composed of a fixed frame, a roller and a conveyor belt, the fixed frame is connected to the telescopic rod of the electric push rod II 14, two rollers are installed on the fixed frame, and a conveyor belt is wound between the two rollers. The electric push rod II 14 drives the conveying member 15 to move toward the side close to each other, so that the conveyor belt on the conveying member 15 can clamp the tubular product, thereby stabilizing the tubular product.

[0032] See Figure 4-Figure 6As shown, the oil filling mechanism includes an oil storage tank 16, an oil pump I 17, an oil pipe I 18, an electric control valve I 19, an oil pump II 20 and an oil pipe II 21; the oil storage tank 16 is installed on the lower side of the base 1, and the oil storage tank 16 is used to store hydraulic oil; the oil pump I 17 is installed on the left side of the oil storage tank 16, and the oil inlet of the oil pump I 17 is connected to the oil storage tank 16; the oil pipe I 18 is connected between the oil inlets of the hydraulic cylinder 10, and the oil pipe I 18 is connected to the oil outlet of the oil pump I 17, so that the oil pump I 17 can pump the hydraulic oil in the oil storage tank 16 into the hydraulic cylinder 10 through the oil pipe I 18, thereby extending the telescopic rod of the hydraulic cylinder 10; the oil pipe Ⅰ18 is equipped with electric-controlled valves Ⅰ19, the same number as the hydraulic cylinders 10. The electric-controlled valves Ⅰ19 can be used to control the hydraulic oil in the oil pipe Ⅰ18 to enter the corresponding hydraulic cylinder 10, so that the telescopic rod of the corresponding hydraulic cylinder 10 can be extended; the oil pump Ⅱ20 is installed on the right side of the oil storage tank 16, and the oil inlet of the oil pump Ⅱ20 is connected to the oil storage tank 16; the oil pipe Ⅱ21 is connected between the oil outlets of the hydraulic cylinder 10, and the oil pipe Ⅱ21 is connected to the oil outlet of the oil pump Ⅱ20, so that the oil pump Ⅱ20 can draw the hydraulic oil in the oil storage tank 16 into the hydraulic cylinder 10 through the oil pipe Ⅱ21, thereby shortening the telescopic rod of the hydraulic cylinder 10.

[0033] In the initial state, the oil tank 16 is filled with hydraulic oil; when in use, the tubular product is passed backward through the middle of the rotating ring 2 until the tubular product is between the conveying members 15, and then the electric push rod I4 drives the friction block 5 to move toward the side close to each other until the friction block 5 clamps the tubular product. At the same time, the electric push rod II14 drives the conveying member 15 to move toward the side close to each other until the conveyor belt on the conveying member 15 clamps the tubular product, thereby stabilizing the tubular product; then the corresponding electric control valve I19 is controlled to open to adjust the interval of the required notch of the outer coating of the tubular product (if the interval of the notch is required to be larger, a small number of electric control valves I19 are controlled to open; if the interval of the notch is required to be smaller, a large number of electric control valves I1 are controlled to open). 9 is opened), and then the hydraulic oil in the oil storage tank 16 is pumped into the corresponding hydraulic cylinder 10 through the oil pipe Ⅰ18 and the corresponding electric control valve Ⅰ19 by the oil pump Ⅰ17, so that the telescopic rod of the corresponding hydraulic cylinder 10 is extended, so that the corresponding hydraulic cylinder 10 drives the carving knife 11 to move to the side close to the tubular product until the carving knife 11 contacts the coating on the surface of the tubular product (when the telescopic rod of the hydraulic cylinder 10 is extended, the hydraulic oil in the hydraulic cylinder 10 will be squeezed out, so that the hydraulic oil in the hydraulic cylinder 10 will flow back to the oil storage tank 16 through the oil pipe Ⅱ21 and the oil pump Ⅱ20), and then the reduction motor 7 drives the screw rod 8 to rotate, so that the movable frame 9, the hydraulic cylinder 10 and the carving knife 11 move forward, so that the carving knife 11 is cut on the coating on the surface of the tubular product. The cutting marks are made in a row, thereby leaving a set of parallel cutting marks on the coating; the hydraulic oil in the oil storage tank 16 is then pumped into the corresponding hydraulic cylinder 10 through the oil pipe Ⅱ 21 by using the oil pump Ⅱ 20, so that the telescopic rod of the corresponding hydraulic cylinder 10 is shortened, thereby causing the corresponding hydraulic cylinder 10 to drive the engraving knife 11 to move to the side away from the tubular product and reset, so that the engraving knife 11 is separated from the coating on the surface of the tubular product. (When the telescopic rod of the hydraulic cylinder 10 is shortened during this period, the hydraulic oil in the hydraulic cylinder 10 will be squeezed out, so that the hydraulic oil in the hydraulic cylinder 10 will flow back to the oil storage tank 16 through the oil pipe Ⅰ 18 and the corresponding electric control valve Ⅰ 19), and then the corresponding electric control valve Ⅰ 19 is controlled to be closed, and only the electric control valve Ⅰ 19 on the far left is left open, and the oil storage tank is again filled with the oil pump Ⅰ 17. The hydraulic oil in 16 is pumped into the corresponding hydraulic cylinder 10 through the oil pipe I 18 and the opened electric control valve I 19, so that the telescopic rod of the corresponding hydraulic cylinder 10 is extended, so that the corresponding hydraulic cylinder 10 drives the carving knife 11 to move to the side close to the tubular product until the carving knife 11 contacts the coating on the surface of the tubular product. Then, the servo motor I 12 drives the gear 13 to rotate, thereby driving the gear ring 3, the electric push rod I 4, the friction block 5 and the tubular product to rotate, so that the carving knife 11 cuts the coating on the surface of the tubular product, and makes this cut perpendicular to the previous set of parallel cuts. Then, the oil pump II 20 is used again to pump the hydraulic oil in the oil storage tank 16 into the corresponding hydraulic cylinder 10 through the oil pipe II 21, so that the telescopic rod of the corresponding hydraulic cylinder 10 is shortened.Thereby, the corresponding hydraulic cylinder 10 drives the carving knife 11 to move to the side away from the tubular product and reset, so that the carving knife 11 is separated from the coating on the surface of the tubular product, and then the reduction motor 7 drives the screw rod 8 to intermittently reverse. When the screw rod 8 reverses, the screw rod 8 drives the movable frame 9, the hydraulic cylinder 10 and the carving knife 11 to move backward a certain distance (the distance moved each time is the same) until the movable frame 9, the hydraulic cylinder 10 and the carving knife 11 move backward and reset. When the screw rod 8 stops reversing, the oil pump Ⅰ 17 can be used again to pump the hydraulic oil in the oil tank 16 into the oil pipe Ⅰ 18 and the opened electric control valve Ⅰ 19. In the corresponding hydraulic cylinder 10, the telescopic rod of the corresponding hydraulic cylinder 10 is extended, so that the corresponding hydraulic cylinder 10 drives the carving knife 11 to move to the side close to the tubular product until the carving knife 11 contacts the coating on the surface of the tubular product again, and then the servo motor Ⅰ 12 drives the gear 13 to rotate again, thereby driving the gear ring 3, the electric push rod Ⅰ 4, the friction block 5 and the tubular product to rotate, so that the carving knife 11 again cuts the coating on the surface of the tubular product, and makes this cut perpendicular to the previous set of parallel cuts. During this period, the rotation of the tubular product will drive the conveyor belt on the conveyor 15 to rotate. The hydraulic oil in the oil storage tank 16 is pumped into the corresponding hydraulic cylinder 10 through the oil pipe II 21 by the oil pump II 20 again, so that the telescopic rod of the corresponding hydraulic cylinder 10 is shortened, thereby causing the corresponding hydraulic cylinder 10 to drive the carving knife 11 to move to the side away from the tubular product and reset, so that the carving knife 11 is separated from the coating on the surface of the tubular product. After that, each time the screw rod 8 stops reversing, the above operation is repeated, so that the carving knife 1 can make cuts on the coating on the surface of the tubular product each time, leaving another set of parallel cuts on the coating, and making this set of parallel cuts perpendicular to the previous set of parallel cuts, thereby The two sets of parallel cuts form a grid pattern, automatically notching the coating on the surface of the tubular product. The leftmost electrically controlled valve I19 is then closed. The tubular product is then held. The electric push rod I4 drives the friction block 5 to move away from each other and reset, causing the friction block 5 to loosen the tubular product. Simultaneously, the electric push rod II14 drives the conveyor member 15 to move away from each other and reset, causing the conveyor belt on the conveyor member 15 to loosen the tubular product. The tubular product is then pulled out from the center of the rotating ring 2, and the subsequent coating adhesion test is then conducted using adhesive tape.

[0034] See Figure 7 and Figure 8As shown, it also includes a gluing mechanism, which includes a guide rail 22, a sliding frame 23, a cylinder 24, a servo motor II 25, an expansion shaft 26, an electric slide rail 27 and a roller 28; the two guide rails 22 are symmetrically arranged on the left and right sides of the lower part of the base 1; the sliding frame 23 is slidably arranged between the two guide rails 22; the cylinder 24 is installed at the lower rear part of the base 1, and the telescopic rod of the cylinder 24 is connected to the sliding frame 23; the two servo motors II 25 are symmetrically arranged on the left and right sides of the lower rear part of the sliding frame 23; the expansion shaft 26 is connected to the output of the servo motor II 25 The servo motor Ⅱ 25 is on the output shaft so that the expansion shaft 26 can be driven to rotate by the servo motor Ⅱ 25, and the reel with the tape is put on the expansion shaft 26. The expansion shaft 26 expands, so that the expansion shaft 26 can fix the reel with the tape, thereby loading the reel with the tape; the electric slide 27 is installed in the middle of the front side of the sliding frame 23; the roller 28 is rotatably connected to the slider of the electric slide 27, so that the electric slide 27 can drive the roller 28 to move, and the roller 28 rolls on the tape, so that the roller 28 can press the tape tightly onto the coating.

[0035] When in use, the reel with the tape wound around it is put on the expansion shaft 26 on the left, and the empty reel is put on the expansion shaft 26 on the right. Then, the expansion shaft 26 is expanded, so that the expansion shafts 26 on the left and right sides can fix the reel with the tape wound around it and the empty reel respectively. Then, the head end of the tape on the reel is pulled through the roller 28 and fixed on the empty reel (the adhesive side of the tape faces downward), and the roller 28 is brought into contact with the top surface of the tape. After that, after closing the electric control valve Ⅰ19 on the far left, the gear 13 can be driven to rotate by the servo motor Ⅰ12, thereby driving the gear ring 3, The electric push rod Ⅰ4, the friction block 5 and the tubular product rotate a quarter of a turn counterclockwise, and then the cylinder 24 drives the slide frame 23, the servo motor Ⅱ 25, the expansion shaft 26, the electric slide rail 27 and the roller 28 to move downward, thereby driving the tape downward, so that the tape is tightly attached to the coating on the surface of the tubular product with glue, and then the electric slide rail 27 drives the roller 28 to move back and forth, so that the roller 28 rolls on the top surface of the tape, so that the roller 28 presses the tape tightly on the cut of the coating, and then the servo motor Ⅱ 25 on the left drives the expansion shaft 26 on the left and the tape wound around it. The reel rotates, and the servo motor Ⅰ 12 drives the gear 13 to rotate in the opposite direction, thereby driving the gear ring 3, the electric push rod Ⅰ 4, the friction block 5 and the tubular product to rotate half a circle clockwise, so that the tubular product pulls the tape on the reel to unwind, and the grid-shaped coating on the surface of the tubular product is affixed with tape. Then, the servo motor Ⅱ 25 on the right drives the expansion shaft 26 on the right and the empty reel to rotate, so that the empty reel reels the tape on the surface of the tubular product, so that the tape leaves the coating on the surface of the tubular product, and then drives the sliding frame 23 and the servo motor Ⅱ 24 through the cylinder 24. 25, the expansion shaft 26, the electric slide rail 27 and the roller 28 move upward and reset, and then the servo motor Ⅰ 12 drives the gear 13 to rotate, thereby driving the gear ring 3, the electric push rod Ⅰ 4, the friction block 5 and the tubular product to rotate a quarter of a turn counterclockwise, so that the coating on the surface of the tubular product can be automatically glued and peeled off, thereby making it convenient for people to conduct adhesion tests on the coating on the surface of the tubular product; when it is necessary to remove the reel on the expansion shaft 26, it is only necessary to contract the expansion shaft 26 to loosen the reel of the expansion shaft 26, and then the reel on the expansion shaft 26 can be removed.

[0036] See Figure 9 and Figure 10As shown, it also includes a brushing mechanism, which includes a support frame 29, a storage tank 30, an electric push rod III 31, a connecting plate 32, a sponge block 33, a connecting pipe 34 and an electric control valve II 35; the support frame 29 is installed on the front of the lower side of the base 1; the storage tank 30 is installed on the upper side of the support frame 29, and the storage tank 30 is used to store pigments; two electric push rods III 31 are symmetrically arranged on the upper side of the support frame 29; the connecting plate 32 is connected between the telescopic rods of the two electric push rods III 31, so that the electric push rod III 31 can drive the connecting plate 32 to rise and fall; the sponge block 33 is connected to the bottom of the connecting plate 32, and the sponge block 33 is used to apply pigment on the coating; the two ends of the connecting pipe 34 are respectively connected to the connecting plate 32 and the storage tank 30, so that the pigment in the storage tank 30 can flow into the sponge block 33 through the connecting pipe 34; the electric control valve II 35 is installed on the connecting pipe 34.

[0037] During use, the pigment (the pigment can be applied to the product, but the pigment cannot be applied to the coating) is added to the storage tank 30 for storage. When the tubular product needs to be drawn out from the middle of the rotating ring 2, the electric push rod III 31 can be used to drive the connecting plate 32 and the sponge block 33 to move downward, so that the sponge block 33 contacts the grid-shaped coating on the surface of the tubular product. Then the electric control valve II 35 is opened to allow the pigment in the storage tank 30 to flow into the sponge block 33 through the connecting pipe 34. Then the tubular product can be drawn out from the middle of the rotating ring 2. During this period, the sponge block 33 will apply the pigment to the grid-shaped coating of the tubular product. After all of them are pulled out and separated from the sponge block 33, the electric control valve II 35 is closed, and then the connecting plate 32 and the sponge block 33 are driven by the electric push rod III 31 to move upward and reset. Then, the pigment condition on the grid-shaped coating of the tubular product is manually observed. If the coating is qualified and there is no shedding, the pigment cannot remain on the coating, resulting in a small amount of residual pigment. If the coating is unqualified and there is shedding, the pigment will remain on the surface of the product, resulting in a large amount of residual pigment. In this way, the manual inspection only needs to observe the residual amount of pigment on the coating of the tubular product to determine whether the coating adhesion test is qualified, thereby facilitating people to complete the protective performance test of the coating.

[0038] See Figure 11 As shown, it also includes an anti-sticking roller 36; two anti-sticking rollers 36 are rotatably provided on the connecting frame 6, and the anti-sticking rollers 36 are used to separate the tape from the connecting frame 6 to prevent the tape from sticking to the connecting frame 6.

[0039] By providing the anti-sticking roller 36, when the tape moves down to fit the coating of the tubular product, the tape can contact the anti-sticking roller 36. In this way, the anti-sticking roller 36 can be used to separate the tape from the connecting frame 6 to prevent the tape from sticking to the connecting frame 6.
