Description

Technical Field

[0001] This application relates to the field of coating performance testing technology, and more specifically, to a coating performance testing fixture. Background Technology

[0002] Paint is a material used to cover the surface of an object to provide protection, decoration, or other special functions. It is generally composed of the following basic components: Film-forming substance: This is the basic component of the paint and is responsible for forming a strong and continuous film on the surface of the object. Common film-forming substances include natural resins, synthetic resins, and oils. Pigments: Used to give the paint color and hiding power, and also to improve the durability and other properties of the coating. Pigments can be inorganic or organic. Solvent: Used to dissolve or dilute the film-forming substance to achieve a suitable viscosity for application. The solvent evaporates after the paint is applied. Depending on environmental protection requirements, the solvent can be organic solvents or water (for water-based paints). Additives are also used to improve the performance of the paint. Paints are widely used in many industries such as construction, automobiles, ships, furniture, and electronic equipment.

[0003] After the existing coatings are processed and produced, their performance needs to be tested to ensure that they are qualified for use when they leave the factory. The main performance tests include abrasion resistance test, heat resistance test, and corrosion resistance test. Currently, when abrasion resistance test is performed on the coating-coated test piece, a tool is used to scrape back and forth, and the abrasion resistance of the coating is determined by manually counting the number of scrapes. This testing method is slow and results in low efficiency in coating performance testing. Utility Model Content

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This application provides a coating performance testing fixture, including: a test fixture body 1, a test platform 101 inside the test fixture body 1, a test piece 102 mounted on the top of the test platform 101, a coating layer 103 coated on the top of the test piece 102, a test assembly disposed inside the test fixture body 1, the test assembly including: an equipment cavity 2, a test electric cylinder 201, a telescopic rod a202, a scraper 203, a photoelectric sensor 204, a counting display screen 205 and a control panel a206, and a lifting assembly disposed at the bottom of the test platform 101, the lifting assembly including: a lifting electric cylinder 3, a telescopic rod b301, a vertical slide rod 302, a support frame 303 and a sliding sleeve b304.

[0031] By using the electric cylinder 201, telescopic rod a202, scraper 203, photoelectric sensor 204, and counting display screen 205 in combination, the wear resistance of the coating layer 103 can be quickly measured.

It effectively improves the work efficiency of coating performance testing, achieving the goal of saving time and labor. The setting of vertical slide bar 302, support frame 303, and sliding sleeve b304 can ensure the stable operation of the test platform 101 and keep the test platform 101 stable.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] Example 1 of the coating performance testing fixture of this application

[0034] This application's coating performance testing fixture includes: a coating performance testing fixture, comprising: a testing fixture body 1, a testing platform 101 inside the testing fixture body 1, a test piece 102 mounted on the top of the testing platform 101, a coating layer 103 coated on the top of the test piece 102, a testing assembly disposed inside the testing fixture body 1, the testing assembly comprising: an equipment cavity 2, a testing electric cylinder 201, a telescopic rod a202, a scraper 203, a photoelectric sensor 204, a counting display screen 205, and a control panel a206, and a lifting assembly disposed at the bottom of the testing platform 101, the lifting assembly comprising: a lifting electric cylinder 3, a telescopic rod b301, a vertical slide rod 302, a support frame 303, and a sliding sleeve b304.

[0035] Among them, the test bench 101 has a fixing block 104 installed on both sides of the top. The outer side of the two fixing blocks 104 is provided with screw holes 105. The screw holes 105 are threadedly connected to the screw rod 106. The outer end of the screw rod 106 is equipped with a handwheel 107. The inner end of the screw rod 106 is rotatably connected to a movable clamping block 108 through a shaft.

[0036] During the coating performance test, the processed coating is first applied to the surface of the test piece 102. After the coating dries and solidifies on the surface of the test piece 102, a testable coating layer 103 is formed. Then, the test piece 102 is placed on the test table 101 with the coating layer 103 facing upwards. At this time, the test piece 102 is located between two movable clamping blocks 108. By grasping the handwheel 107 and rotating the screw 106 clockwise, the screw rotates inside the screw hole 105. That is, the screw 106 pushes the movable clamping block 108 toward the test piece 102, so that the movable clamping block 108 can clamp and fix the test piece 102 on the test table 101, preventing the test piece 102 from falling off the test table 101 during the wear resistance test of the coating layer 103.

[0037] Each movable clamp 108 is equipped with an anti-slip block 109 on its inner side. The anti-slip block 109 is made of rubber material. When the movable clamp 108 clamps the test piece 102, the anti-slip block 109 increases the friction between the movable clamp 108 and the test piece 102, increases the clamping tightness of the movable clamp 108 on the test piece 102, and prevents the movable clamp 108 from loosening with the test piece 102.

[0038] The test fixture body 1 is equipped with a lifting electric cylinder 3 inside. The top of the lifting electric cylinder 3 is equipped with a telescopic rod b301 that is connected to the test platform 101. Vertical slide rods 302 are installed on both sides of the bottom of the test platform 101. Support frames 303 are installed on both sides of the outer end of the lifting electric cylinder 3. Sliding sleeves b304 that are slidably connected to the vertical slide rods 302 are installed on both support frames 303.

[0039] After the test piece 102 is clamped and fixed on the test bench 101, since the lifting electric cylinder 3 is electrically connected to the control panel a206, the lifting electric cylinder 3 is activated via the control panel a206. The lifting electric cylinder 3 drives the telescopic rod b301 to move upward, causing the telescopic rod b301 to push the test bench 101 and the test piece 102 upward. When the test piece 102 moves upward, the coating layer 103 on the top of the test piece 102 will be in close contact with the bottom of the scraper 203 (e.g., Figure 2 As shown), at this time, the lifting electric cylinder 3 is turned off through the control panel a206. After adjusting and aligning the position of the coating layer 103 on the top of the test piece 102 with the scraper 203, the wear resistance test of the coating layer 103 can be performed by moving the scraper 203 back and forth.

[0040] When the telescopic rod b301 pushes the test bench 101 and the test piece 102 to move up and down, the test bench 101 is slidably connected to the sliding sleeve b304 on the support frame 303 through the vertical sliding rods 302 on both sides of the bottom. The arrangement of the vertical sliding rods 302, the support frame 303 and the sliding sleeve b304 can ensure that the test bench 101 runs stably up and down and keeps the test bench 101 stable.

[0041] Example 2

[0042] Based on Embodiment 1, a device cavity 2 is provided on one side of the test fixture body 1. A test electric cylinder 201 is installed inside the device cavity 2. A telescopic rod a202 is installed at one end of the test electric cylinder 201. A scraper 203 is installed at one end of the telescopic rod a202. A photoelectric sensor 204 is installed at the top inside the test fixture body 1. A counting display screen 205 electrically connected to the photoelectric sensor 204 is installed on the outside of the test fixture body 1. A control panel a206 is installed on the outside of the test fixture body 1. The control panel a206 is electrically connected to the test electric cylinder 201 and the photoelectric sensor 204 respectively.

[0043] After pushing the test piece 102 upwards to ensure the coating layer 103 is tightly attached to the bottom of the scraper 203, the test electric cylinder 201 and photoelectric sensor 204 are activated via the control panel a206. The test electric cylinder 201 drives the telescopic rod a202 to push the scraper 203 back and forth on the coating layer 103, performing abrasion resistance testing on the coating layer 103. During the back and forth movement of the scraper 203, the scraper 203 is positioned close to the photoelectric sensor 204. At this time, the photoelectric sensor 204 detects the scraper 203 using infrared light. When the scraper 203 passes the photoelectric sensor 204, the infrared light is blocked and reflected at the scraper 203, thus triggering a count. Each time the scraper 203 is illuminated by infrared light at the photoelectric sensor 204, it is counted once. After triggering the count, the photoelectric sensor 204 transmits the signal to the counting display screen 205 as an electrical signal. The count can be displayed on the counting display screen 205. The number of times the scraper 203 scrapes back and forth is displayed. When conducting abrasion resistance testing on the coating layer 103, the wear condition of the coating layer 103 can be observed through the observation window 501. When the coating layer 103 is completely worn away, the test electric cylinder 201 and photoelectric sensor 204 are turned off through the control panel a206. Then, the operator can use a mobile phone or laptop to record the number of scrapings displayed on the counting display screen 205, thereby quickly measuring the abrasion resistance of the coating layer 103. When the coating leaves the factory, the number of abrasion resistance tests can be recorded on the instruction manual or packaging bag. When the coating is put into the market, consumers or customers can clearly know the abrasion resistance of the coating. This solves the problem of low efficiency in the current method of manually scraping back and forth on the coated test piece with a tool and manually counting the number of scrapings to determine the abrasion resistance of the coating. It effectively improves the work efficiency of coating performance testing and achieves the purpose of saving time and labor.

[0044] The electrical power of the test fixture body 1 in this application is provided by an external power source, and the control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0045] The test fixture body 1 has two shielding doors 5 on its outer side, and each shielding door 5 is equipped with an observation window 501. The test fixture body 1 has two hidden grooves 502 on its inner sides that are used in conjunction with the two shielding doors 5. The bottom of each hidden groove 502 is equipped with a slide rail 503 that is slidably connected to the two shielding doors 5.

[0046] During the scratch abrasion test of the coating layer 103 inside the test fixture body 1, the two shielding doors 5 are pulled closer to each other to shield the inside of the test fixture body 1, preventing the debris generated by the scratching from flying out and preventing the flying debris from getting into the eyes of the staff. When replacing the test piece 102, the two shielding doors 5 are pulled open and moved into the hidden grooves 502 on both sides inside the test fixture body 1, so that the two shielding doors 5 are placed in the hidden grooves 502 without affecting the disassembly and replacement of the test piece 102.

[0047] Example 3

[0048] Based on Example 1, the test fixture body 1 is equipped with two transverse sliding rods 207 inside. The scraper block 203 is equipped with a sliding sleeve a208 that is slidably connected to the two transverse sliding rods 207 on the outside. When the telescopic rod a202 pushes the scraper block 203 to move back and forth on the coating layer 103, the scraper block 203 slides back and forth on the two transverse sliding rods 207 through the sliding sleeve a208 to ensure that the scraper block 203 runs stably from left to right and keeps the scraper block 203 stable.

[0049] Limiting blocks 4 are installed at the outer ends of the two horizontal slide bars 207 and the bottom ends of the two vertical slide bars 302. During use, the two horizontal slide bars 207 and the two vertical slide bars 302 are equipped with limiting blocks 4 at their outer and bottom ends. The limiting blocks 4 prevent the scraper block 203 from sliding off the horizontal slide bar 207 and prevent the vertical slide bar 302 from sliding off the support frame 303, ensuring that the horizontal slide bars 207 and the vertical slide bars 302 can be used normally.
