Description

Technical Field

[0001] This utility model relates to the field of coating and pressing testing equipment, and more specifically, to an online pressing testing device for coating and substrate. Background Technology

[0002] Peel strength testing is a core method for evaluating the adhesion performance between the coated material and the substrate, used to determine the durability and reliability of the composite structure. This test simulates the separation forces experienced by the material during use, slowly peeling the coated layer from the substrate at a specific angle and measuring the force required throughout the process. The peeling process must be kept smooth and at a constant speed to ensure the test results accurately reflect the interfacial bonding strength. Stable and high peel force indicates good adhesion; easy peeling, localized delamination, or large fluctuations in force value indicate quality problems such as insufficient surface treatment, poor bonding, or poor material compatibility.

[0003] Peel strength testing of coated products mostly employs offline testing of finished products. Typically, samples are cut from the roll of material after production and sent to the laboratory for testing. This method has significant efficiency bottlenecks; it is not only time-consuming and labor-intensive but also has a long testing cycle, failing to reflect quality fluctuations during the production process in a timely manner. Due to the low sampling frequency and lag, once poor adhesion is detected, a large number of defective products have often already been produced, resulting in serious waste.

[0004] How to design an online lamination and testing device for coating and substrate to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides an online pressing and testing device for coating and substrate, which aims to improve the problems mentioned in the background.

Multiple sets of uprights are fixedly connected to the top of the base. A first roller group is rotatably connected to one set of uprights, and a second roller group is rotatably connected to another set of uprights. A coating substrate is disposed between the first and second roller groups. A motor is fixedly connected to the side wall of one of the uprights, and multiple sliding rods are fixedly connected to the side wall of the upright. A ball screw is rotatably connected to the side wall of the upright. A sampling component is disposed on one side of the ball screw. The sampling component includes a fixed seat. A screw nut and multiple sliding blocks are fixedly connected to the outer wall of the fixed seat. The sliding blocks are slidably connected to the sliding rods.

The upper pressure strip is arranged in a "U" shape, and the upper cutter is arranged on the inner side of the upper pressure strip.

[0009] Preferably, a lower pressure plate is slidably connected to the bottom of the sliding seat, and a lower cutting blade is fixedly connected to the top of the lower pressure plate. The lower cutting blade is perpendicular to the upper cutting blade.

Multiple slide rods 8 are fixedly connected to the side wall of the uprights 2. A ball screw 9 is rotatably connected to the side wall of the uprights 2. A sampling component is disposed on one side of the ball screw 9. The sampling component includes a fixed seat 11. A screw nut 12 and multiple slide seats 13 are fixedly connected to the outer side wall of the fixed seat 11. The slide seats 13 are slidably connected to the slide rods 8. The ball screw 9 is drivenly connected to the screw nut 12. The output shaft of the motor 5 is drivenly connected to the end of the ball screw 9 through a synchronous belt. The first roller group 3 and the second roller group 4 are used to convey the lamination substrate. The lamination substrate between the two roller groups maintains a constant linear speed. Both the output shaft of the motor 5 and the end of the ball screw 9 are fixedly equipped with synchronous pulleys. Synchronous belts are provided on the two synchronous pulleys. The motor 5 drives the ball screw 9 to rotate through the synchronous belts. When the ball screw 9 rotates, it drives the screw nut 12 to move axially. The slide block 13 is slidably connected to the slide rod 8 to ensure the stability of the axial movement of the screw nut 12.

[0019] A cylinder 16 and a sliding seat 17 are fixedly connected to the inner wall of the fixed seat 11. The cylinder 16 is located above the sliding seat 17. An upper pressure plate 18 is fixedly connected to the telescopic rod at the bottom of the cylinder 16. An upper cutter 19 is fixedly connected to the bottom of the upper pressure plate 18. The upper cutter 19 is tubular and has an annular cutting edge at its bottom. The end of the upper pressure plate 18 is slidably connected to the sliding seat 17. A reinforcing strip 20 is fixedly connected to the bottom of the upper pressure plate 18. Multiple first telescopic rods 21 are fixedly connected to the bottom of the reinforcing strip 20. Springs 22 are sleeved on the first telescopic rods 21. An upper pressure strip 23 is fixedly connected to the bottom of the multiple first telescopic rods 21. The upper pressure strip 23 is U-shaped. The upper cutter 19 is located inside the upper pressure strip 23. A lower pressure plate 26 is slidably connected to the bottom of the sliding seat 17. A lower cutter 27 is fixedly connected to the top of the lower pressure plate 26. The lower cutter 27 is perpendicular to the upper cutter 19. In the corresponding position, the cutting edge of the upper cutter 19 extends outward at the bottom, and the cutting edge of the lower cutter 27 extends inward at the top. Multiple second telescopic rods 28 are fixedly connected to the lower pressure plate 26, and a lower pressure bar 29 is fixedly connected to the top of the multiple second telescopic rods 28. A first rack 31 is fixedly connected to the bottom of the upper pressure plate 18. A gear 32 is rotatably connected to the side wall of the sliding seat 17. A second rack 33 is fixedly connected to the top of the lower pressure plate 26. The gear 32 is disposed between the first rack 31 and the second rack 33.

The bottom end of the third telescopic rod 30 is fixedly connected to the top of the lower pressure plate 26. By setting both ends of the third telescopic rod 30 to be connected to the upper pressure plate 18 and the lower pressure plate 26, the stability of the upper pressure plate 18 and the lower pressure plate 26 when they move towards each other is maintained.

[0020] Motor 5 drives the lead screw nut 12 to move on the ball screw 9, making the linear velocity of the lead screw nut 12 the same as the linear velocity of the coated substrate. Then, the telescopic rod at the bottom of the cylinder 16 extends downward, pushing the upper pressure plate 18 downward, causing the upper pressure plate 18 to slide on the fixed seat 11. The upper pressure plate 18 drives the gear 32 to rotate through the first rack 31 on it. The gear 32 drives the second rack 33 to move upward, causing the lower pressure plate 26 to move upward synchronously. When the upper pressure plate 18 and the lower pressure plate 26 approach each other, the spring 22 drives the upper pressure strip 23 and the lower pressure strip 29 to approach and clamp the coated substrate to prevent the shearing force during subsequent sampling from affecting the surface tension of the coated substrate. The telescopic rod of the cylinder 16 continues to extend, causing the upper cutter 19 to enter the inside of the lower cutter 27. The shearing force generated by the movement of the two cutters removes a sample of a specific size from the coated substrate. The sample falls into the collection box through the through hole below the lower pressure plate 26 for subsequent peel strength testing. After sampling is completed, the two cutters are reset by controlling the retraction of the telescopic rod of cylinder 16.

[0021] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
