Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a UV curing coating adhesion detection device. Background Art

[0002] As is well known, UV-curable coatings are rapidly cured by ultraviolet (UV) light and contain a photosensitizer and reactive resin. Once applied to a substrate and exposed to UV light, the photosensitizer triggers a chemical reaction, causing the resin to crosslink and harden rapidly into a durable coating within seconds. These coatings are widely used in the automotive, electronics, printing, and packaging industries due to their fast curing speed, excellent wear resistance, and environmental friendliness. However, the adhesion of UV-cured samples typically requires testing using a test device to measure the adhesion between the coating and the sample.

[0003] However, traditional UV-curing coating adhesion testing equipment is usually designed for samples of standard size, such as standard test pieces or substrates of specified size. For samples of non-standard size or shape, specific fixtures or adjustment devices may be required, which increases the complexity of operation. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and propose a UV curing coating adhesion detection device. When the UV curing coating adhesion detection device is used, the sample is placed above the pressure sensor, and the servo motor is started to drive the bidirectional threaded rod to rotate and the threaded sleeve to move in the opposite direction. The movement of the threaded sleeve drives the upper clamping pad to move together, and then continuously approaches the sample surface to clamp it. By adjusting the position and movement mode of the clamping pad, non-standard size samples can be easily processed without replacing the fixture or making complicated adjustments.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The UV curing coating adhesion testing device includes a mounting base, a positioning mechanism, and a testing mechanism. The positioning mechanism includes a storage slot located in the middle of the bottom surface of the mounting base. Both sides of the inner wall of the storage slot are rotatably connected to a bidirectional threaded rod. Both sides of the bidirectional threaded rod are sleeved with threaded sleeves. The upper ends of the threaded sleeves are fixedly connected to clamping pads.

[0007] The detection mechanism includes a mounting block, the upper end of the mounting block is fixedly connected to the middle of the top surface of the mounting seat, a mounting groove is opened in the middle of the lower surface of the mounting block, the inner walls of the front and rear ends of the mounting groove are rotatably connected with a threaded rod, the middle part of the threaded rod body is sleeved with a moving block, the lower end of the moving block is fixedly connected to a positioning block, the lower end of the positioning block is fixedly connected to an electric telescopic rod, and the lower end of the electric telescopic rod is fixedly connected to a scratching knife.

[0008] By using the above technical solution, compared with the existing UV curing coating adhesion detection device, when the UV curing coating adhesion detection device is used, the servo motor 2 is started to drive the threaded rod to rotate and the movable block is driven to move at the same time, and can be moved to the top of the sample as required. By setting the pressure sensor threshold according to the required sample specifications, the electric telescopic rod is started to drive the scratch knife to press down continuously. At this time, the pressure sensor value continues to increase. When the required threshold is reached, an electrical signal is sent to the electric telescopic rod to retract. At this time, the depth, width and length of the scratch are checked. Deeper or wider scratches usually indicate poor adhesion and higher practical performance.

[0009] Furthermore, a PLC control panel is provided on one side of the lower portion of the outer wall of the front end of the mounting base;

[0010] Through the above technical solution, the servo motor 1, servo motor 2, electric telescopic rod and pressure sensor are electrically connected through the PLC control panel, which facilitates the control of their switches.

[0011] Furthermore, a sample is placed in the middle of the bottom surface of the mounting seat, and pressure sensors are embedded in the front and rear ends of the bottom surface of the mounting seat near the middle.

[0012] Through the above technical solution, the uniformity and accuracy of the force applied to the sample can be easily monitored in real time through the pressure sensor.

[0013] Furthermore, the lower end of the sample is tightly fitted with the lower end of the pressure sensor;

[0014] Through the above technical solution, the lower end of the sample is tightly fitted with the lower end of the pressure sensor, ensuring that there is no gap between the sample and the pressure sensor, so that the force applied to the sample can be accurately transmitted, reducing errors and improving measurement accuracy.

[0015] Furthermore, a protective shell 1 is fixedly connected to the middle of the outer wall on the other side of the mounting base, a servo motor 1 is fixedly connected to the middle of the inner wall on the other side of the protective shell 1, and an output end of the servo motor 1 passes through the protective shell 1 to the interior of the storage tank and is fixedly connected to the outer wall on the other side of the bidirectional threaded rod;

[0016] Through the above technical solution, the bidirectional threaded rod is driven to rotate by the servo motor.

[0017] Furthermore, the threaded sleeves are all slidably connected inside the storage groove;

[0018] According to the above technical solution, the threaded sleeves are all slidably connected inside the storage groove, which makes it easy to limit the threaded sleeves and allow them to move horizontally.

[0019] Furthermore, a second protective shell is fixedly connected to the upper portion of one side of the rear end outer wall of the mounting seat, a second servo motor is fixedly connected to the rear end of the inner wall of the second protective shell, and an output end of the second servo motor passes through the second protective shell to the interior of the mounting slot and is fixedly connected to the outer wall of the rear end of the threaded rod;

[0020] Through the above technical solution, the threaded rod is easily driven to rotate by the servo motor 2.

[0021] Furthermore, the moving block is slidably connected inside the mounting groove;

[0022] With the above technical solution, the movable block is slidably connected inside the installation groove to facilitate limiting the movable block so that it can move longitudinally.

[0023] The utility model has the following beneficial effects:
