Description

Technical Field

[0001] The present invention relates to the technical field of hundred-grid detection, and in particular to a hundred-grid detection device. Background Art

[0002] In the coating adhesion test, the grid test is a commonly used test method for evaluating the bonding strength between the coating and the substrate. The traditional grid test relies on manually using a grid knife to scratch the coating surface, and then sticking tape on it for tearing test. However, there are some problems with this test method. First, it is difficult to ensure the uniformity and accuracy of the scribing by manual scribing, because the operator's strength and angle may be inconsistent, thus affecting the accuracy of the test results. Secondly, the traditional grid knife needs to apply force manually during operation, and it is difficult to control the depth and consistency of the scribing, which may also cause deviations in the test results. In addition, for coatings with large areas or complex shapes, the operating efficiency of the traditional grid knife is low, and uneven force is prone to occur during the tearing of the tape, resulting in uneven paint surface under peeling. These problems limit the wide application of the traditional grid knife in coating adhesion testing. Therefore, the present invention aims to provide a grid detection device that can automatically and accurately scribble, is easy to operate, and has high efficiency, so as to solve the inconvenience of the traditional grid knife in use.

[0003] For example, the specification of "A 100-grid testing device" disclosed in Chinese invention patent CN113281255A discloses: According to Japanese industrial standards, it is divided into 1 to 5 levels. The higher the level, the stricter the requirements. When the customer specification requires level 5, it means that there must be no shedding. Most of the existing 100-grid tests still use manual scratching. Manual scratching has problems such as inaccurate scratching position and inconsistent scratching force, which leads to inconsistent scratch position and depth. Therefore, a new 100-grid testing device is urgently needed to solve the above problems; the above patent can prove the defects of the existing technology.

[0004] Therefore, we make improvements to this problem and propose a hundred-grid detection device. Summary of the invention

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] As described in the background art, the traditional grid knife needs to apply force manually during operation, and it is difficult to control the depth and consistency of the marking, which may also lead to deviations in the test results.

A guide ring 816 for guiding waste chips to the expansion plate 807 is fixedly connected to the bottom outer wall of a single action circle 815, and two grooves 817 are provided on the inner wall of the single action circle 815, and a driving rod 818 is hinged in the groove 817, and an arc edge plate 819 is hinged between the two driving rods 818. An annular groove 820 is provided on the action circle 815, and two grid knives 821 are fixedly connected to the outer wall of the action circle 815, and a capsule 822 is connected in the annular groove 820. It should be supplemented that the inner ring of the capsule 822 is a non-elastic structure and is fixed to the bearing in the annular groove 820.

[0048] The present invention provides a grid detection device, which uses a grid knife 821 that moves in the horizontal and vertical directions, so that dragging and marking in the horizontal and vertical directions are completed under the action of two drag chains, so that the plate on the adsorption plate 906 can generate small grid marks on the paint surface on the plate surface under the stable grid knife 821, providing an observable area generation for the subsequent detection process. It should be added that the air pressure filled in the two capsules 822 is different, the air pressure in one of the capsules 822 is smaller and can be squeezed by the test tape 813, while the air pressure in the other capsule 822 is smaller and cannot be squeezed by the test tape 813;

[0049] The driving rod 818 is used to change the angle of the two arc-shaped plates 819, so that the arc-shaped plates 819 and the inner wall of the action circle 815 present different angles, so that negative pressures in different directions are generated during the rotation process.

[0050] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A hundred-grid detection device, the testing device 8 also includes an electric push rod 801 fixedly connected to the sliding table 7 and extending through the groove 6 to the bottom of the sliding plate 5. The electric push rod 801 extends to the sliding plate 5 and one end is fixedly connected to an adsorption tube 802 for cleaning waste chips. A fixed rod 803 is fixedly connected to the electric push rod 801, and the end of the fixed rod 803 is fixedly connected to a first drive motor 804.

[0054] The driving structure through the through slot 6 is adopted so that the electric push rod 801 can be stable during the movement in the through slot 6, so that the engraving effect can be clearly divided, resulting in the grid division of the engraving surface on the plate being clear and observable.

[0055] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 A hundred-grid detection device, the test device 8 also includes a main console 805 fixedly connected to the output end of the first drive motor 804 through a coupling, the main console 805 is fixedly connected to the second drive motor 806, the output end of the second drive motor 806 is fixedly connected to the expansion plate 807, the expansion plate 807 and the main console 805 are connected to the internal space of the adsorption tube 802, and a storage tube 808 is fixedly connected to the top outer wall of the sliding plate 5, and the storage tube 808 is connected to the adsorption tube 802.

[0056] By using two independent and interconnected driving motors, the expansion plate 807 connected thereto can realize two actions: rotation and flipping, thereby enabling the rectangular frame 810 above it to have different orientations.

[0057] The testing device 8 also includes a circular frame 809 fixedly connected to the outer wall at the bottom of the expansion plate 807, a rectangular frame 810 fixedly connected to the circular frame 809, a cross rod 814 fixedly connected to the rectangular frame 810, a plurality of winding rollers 811 for winding up the tape are arranged on the circular frame 809, a plurality of brake blocks 812 are fixedly connected to the circular frame 809, a test tape 813 is arranged on the winding roller 811, and a test tape 813 is arranged between the two winding rollers 811.

[0058] The testing device 8 also includes a sliding groove 8111 opened on the rectangular frame 810, in which a sliding rod 8112 is slidably connected, one end of the sliding rod 8112 is fixedly connected to a buffer spring 8113, the buffer spring 8113 is fixedly connected to the rectangular frame 810, and the other end of the sliding rod 8112 is rotatably connected to the winding roller 811.

[0059] A sliding rod 8112 that can slide on the rectangular frame 810 is used, so that it can play a certain buffering role in the process of contacting the plate. At the same time, there is a certain time in the buffering process to ensure that the action circle 815 contacts the test tape 813 and fits the plate.

[0060] Example 2 further optimizes the grid detection device provided in Example 1. Specifically, Figure 7 , Figure 8 and Fig. 9 As shown, the buffer spring 8113 is disposed in the sliding groove 8111 of the rectangular frame 810 , and the single test tape 813 is wound on the two winding rollers 811 in opposite directions.

[0061] There are two guide rings 816 , each of which is a funnel-shaped structure with a rectangular opening on one side and a circular opening on the other side.

[0062] Example 3 further optimizes a grid detection device provided in Example 1 or 2. Specifically, Fig.11 As shown, the fixing device 9 includes a conveyor belt 901 arranged on the base 1 , a moving groove 902 is opened on the base 1 , an air pump 903 is slidably connected in the moving groove 902 , and a fixing plate 904 is fixedly connected to the conveyor belt 901 .

[0063] The conveyor belt 901 structure is adopted to allow different distances and angles to appear between the engraved plate and the grid knife 821. Under the condition that only the grid knife 821 of the same size is used, the angle between the plate and the grid knife 821 can be changed by changing the angle, and the engraving depth can be changed by changing whether the plate is in contact with the flat surface or the tip of the grid knife 821.

[0064] Further, such as Fig.11As shown, the fixing device 9 also includes a plurality of L-shaped rods 905 fixedly connected to the fixing plate 904, an adsorption plate 906 is fixedly connected to the top outer wall of the fixing plate 904, two air pipes 907 are arranged on one side of the adsorption plate 906, and the air pump 903 is fixedly connected to the air pipe 907 and is connected thereto.

[0065] The air pump 903 has two functions. It applies negative pressure to the bottom of the plate so that the plate can be better adsorbed on the adsorption plate 906. At the same time, the bottom of the L-shaped rod 905 is connected to the output end of the air pump 903. When the air pump 903 is evacuated, negative pressure is generated at the bottom of the L-shaped rod 905, which then descends to produce an extrusion force on the plate, so that the plate is stably set on the adsorption plate 906 under the two conditions.

[0066] Further, such as Fig.11 As shown, there are three L-shaped rods 905 , which are respectively arranged on three sides of the adsorption plate 906 .

[0067] The use process of a hundred-grid detection device provided by the present invention is as follows:

[0068] 1. Place the plate on the adsorption plate 906, and start the air pump 903 to make the air pump 903 start working and make the fine holes on the adsorption plate 906 have adsorption force through the air pipe 907. At this time, negative pressure is generated between the adsorption plate 906 and the plate, and the plate is adsorbed. At this time, the L-shaped rod 905 starts to descend and clamps the plate, and the fixed plate 904 is transported to the processing position below the test device 8 through the conveyor belt 901. At this time, the air pump 903 is pulled to the same position as the fixed plate 904 with the assistance of the moving groove 902 and the conveyor belt 901;

[0069] 2. As mentioned above, the air pressure in the two capsules 822 is different, and it should be added that the rectangular frame 810 and the circular frame 809 have two sides close to the test tape 813 with slots connected to the outside. At this time, the capsule 822 with lower air pressure needs to be directed toward one of the slots under the action of the drive shaft 8141 and the action circle 815. At this time, the slot needs to face the plate to be engraved. When the engraving angle is adjusted by the first drive motor 804 and the second drive motor 806, the electric push The rod 801 makes the rectangular frame 810 gradually approach the plate. When the reel 811 contacts the fixed plate 904, it is gradually squeezed by the sliding rod 8112 and the buffer spring 8113 and gradually becomes flush with the rectangular frame 810. At this time, the reel 811 at both ends begins to reel and straighten the test tape 813. The reeling action is provided by the internal drive motor. The component is an existing structure and is not disclosed. At this time, the test tape 813 is not sticky on the side close to the capsule 822. At this time, the straightened test tape 8 13 The low-pressure capsule 822 is squeezed. After being squeezed by the test tape 813, the low-pressure capsule 822 will expose the grating knives 821 on both sides of the action circle 815, so that the grating knives 821 can be more easily contacted with the plate. At the same time, since one side of the capsule 822 is squeezed, the gas will gather on the other side of the capsule 822, so that the side of the capsule 822 close to the drive shaft 8141 will expand and squeeze the drive shaft 8141, so that the action circle 815 sliding thereon moves in a direction away from the drive shaft 8141, that is, the plate side. This causes a relative movement between the action circle 815 and the drive shaft 8141, so that the action circle 815 completely protrudes from the enclosed structure, preventing the structure from being too short and causing the grid knife 821 to be unable to contact the plate. The sliding action rebounds through the spring. When the rebound effect does not take effect, it will be captured by the brake block 812 on the inner wall of the circular frame 809 to limit its rotation. Under the action of the first drag chain 3 and the second drag chain 10 of the two drag chains, the grid knife completes the vertical and horizontal dragging on the plane to complete the division of the grid;

[0070] 3. After the engraving is completed, a considerable amount of residue will remain on the plate. At this time, the rectangular surface of the arc edge plate 819 is directed toward the plate by the action of the motor. Figure 6In the state shown, the plate is facing, and the two action circles 815 are rotated by the driving shaft 8141. At this time, air pressure is generated due to the angle between the arc edge plate 819 and the action circle 815, and the angle between the arc edge plate 819 and the action circle 815 is changed to a positive angle or a negative angle by the driving rod 818, thereby generating airflows in different directions, that is, changing the direction of the fan blades changes the direction of the wind force, so that the residue is guided to the expansion plate 807 by the guide circle 816 while being adsorbed, and is collected in the storage tube 808. At this time, the direction of the arc edge plate 819 is constantly changed to generate a changing airflow, and through the tearing effect of the wind force, a part of the residue interfering with the test is separated from the measured area under the pulling effect of the wind force, thereby preventing the accuracy of the interference test;

[0071] 4. After completing the above process, a laminating operation is required, that is, the test tape 813 is in contact with the plate, and the adhesion between the paint surface and the plate is tested by the paint surface peeled off thereon. The rectangular frame 810 is restored to the state in step 2, that is, the slot on the rectangular frame 810 is facing the plate. At this time, the capsule 822 with a larger air pressure is facing the plate, and the test tape 813 on the winding roller 811 is loosened. At the same time, the plate is approached so that the capsule 822 pushes the test tape 813 to contact the plate and complete the fitting. Finally, the test tape 813 is separated from the plate through the action of the electric push rod 801, so that the entire hundred-grid test completes all steps and completes data collection through observation and measurement.
