Description

Technical Field

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

[0002] The adhesion strength between the coating and the substrate directly affects the structural strength, durability, aesthetics and service life of the product. Therefore, it is necessary to test the adhesion of the coating. Among them, the cross-hatch method is a commonly used detection method. This method requires making multiple mutually perpendicular cutting lines on the sample surface to form a grid pattern. After cleaning the sample surface, stick tape on it. After ensuring that the tape is in full contact with the test area, quickly tear off the tape and observe the shedding of the coating to rate the coating adhesion.

[0003] A Chinese patent with publication number CN113340806A discloses an adhesion detection device and a detection method thereof. The solution includes an operating table, a mounting frame, a positioning assembly, a rotating frame, a cutting frame and a gluing assembly. The positioning assembly is slidably connected to the operating table, and the cutting frame includes a tool. The above solution uses the positioning assembly to fix the workpiece, and then rotates the cutting frame to the top of the workpiece and makes the cutting frame close to the workpiece. By moving the workpiece, the coating on the surface of the workpiece is cut.

[0004] According to the requirements of relevant testing standards, the spacing between cutting lines needs to be adjusted according to the thickness of the coating and the type of substrate. When the above solution is used, in order to adapt to coatings of different thicknesses, the tool needs to be replaced, additional tools need to be prepared, and the operation is relatively complicated. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A coating adhesion detection device comprises a base, a mounting seat, a cutting mechanism, a first adjustment component and a second adjustment component. A fixing mechanism is arranged on the top of the base, and the fixing mechanism is used to fix a sample. The mounting seat is annular and is rotatably arranged on the top of the base. Two sliding rods are symmetrically arranged on the top of the mounting seat, and a slider is slidably sleeved on the two sliding rods. The cutting mechanism comprises a mounting block and a blade. The mounting block is arranged below the slider, and the mounting block has an inner cavity. A first screw is rotatably inserted in the inner cavity. The blade is arranged in N numbers. A knife handle is fixedly arranged on the top of each blade. The knife handle is slidably sleeved on the first screw. A limiting block is provided at the front of the first screw. The limiting block and the top of each knife handle are slidably abutted against the top wall of the inner cavity. The bottom of the blade extends out of the bottom of the mounting block. The first adjustment component is arranged in the inner cavity and is located on the left side of the first screw. The first adjustment component comprises a first partition plate for separating two adjacent blades. The second adjustment component is arranged in the inner cavity and is located on the right side of the first screw. The second adjustment component comprises a second partition plate for separating two adjacent blades.

[0008] The principle and effect of this technical solution:

[0009] Place the sample on the top of the base and fix it by a fixing mechanism. According to the coating thickness and substrate type of the sample, place the first partition or the second partition between two adjacent tool handles to adjust the spacing between two adjacent blades. Rotate the first screw to make the limit block press against each tool handle, then lower the mounting block to make the blade contact with the sample, slide the slider along the slide bar to draw N cutting lines on the surface of the sample, then rotate the mounting seat 90°, slide the slider again, and slide out a grid on the surface of the sample.

[0010] Through the above arrangement, by using the first partition or the second partition to be clamped between two adjacent blades, the device can adjust the distance between the two adjacent blades according to the coating thickness and substrate type of the sample, thereby solving the problem of the above solution requiring additional preparation of cutting tools and more complicated operation.

[0011] In the utility model, the first adjustment component also includes a first U-shaped frame and a second screw, the second screw is threadedly penetrated through the left side wall of the inner cavity, the first U-shaped frame is slidably arranged in the inner cavity, and one end of the second screw extends into the inner cavity and is rotatably connected to the first U-shaped frame, a first cross bar is laterally arranged along the inner edge of the first U-shaped frame, the first partition is arranged as N-1, and are respectively slidably sleeved on the first cross bar, the front part of the first cross bar is sleeved with a first compression spring, the left end of the tool handle and the right end of the first partition are respectively provided with first guide push bevels that cooperate with each other, and the first guide push bevel at the left end of the tool handle and the first guide push bevel at the right end of the first partition are alternately arranged.

[0012] In the utility model, the second adjustment assembly also includes a second U-shaped frame and a third screw. The third screw is threadedly penetrated through the right side wall of the inner cavity. The second U-shaped frame is slidably arranged in the inner cavity, and one end of the third screw extends into the inner cavity and is rotatably connected to the second U-shaped frame. A second cross bar is laterally arranged along the inner edge of the second U-shaped frame. The second partition plates are arranged in N-1 numbers and are respectively slidably sleeved on the second cross bar. A second compression spring is sleeved on the front part of the second cross bar. The right end of the knife handle and the left end of the second partition plate are respectively provided with second guide push inclined surfaces that cooperate with each other.

[0013] In the present invention, the thickness of the handle is t1, the thickness of the first partition is t2, and the thickness of the second partition is t3, which is set to t1=t2=0.5×t3.

[0014] The principle and effect of this technical solution:

[0015] In the initial state, the limit block pushes the tool handles to abut against each other, the first guide bevels at the left end of the tool handle and the right end of the first partition plate fit together, and the spacing between the blades is t1, which is the use state one; the first screw is rotated in the opposite direction to make the limit block move away from the tool handle, and then the second screw is rotated to push the first U-shaped frame and each first partition plate close to the first screw. In this process, the first partition plate is displaced in the front and rear directions at the same time under the action of the first guide bevels, until the first guide bevels at the left end of the tool handle and the first guide bevels at the right end of the first partition plate are arranged alternately, and the limit block is driven again. The positioning block is pressed against the tool handle. At this time, the spacing between the blades is t1+t2=2×t1, and the second guide slopes at the right end of the tool handle and the left end of the second partition are arranged alternately. This is the second usage state; after the limiting block is moved away from the tool handle again, the third screw is rotated to push the second U-shaped frame and the second partitions close to the first screw. In this process, the second partitions are displaced along the front and rear directions at the same time under the action of the second guide slopes until the second partitions and the tool handles are arranged alternately. At this time, the spacing between the blades is t1+t3=3×t1. This is the third usage state.

[0016] Through the above arrangement, the purpose of clamping each first partition or each second partition between two adjacent tool handles is achieved. At the same time, by setting the first compression spring and the second compression spring, each first partition or each second partition can be easily reset after the detection is completed.

[0018] The principle and effect of this technical solution:

[0019] Since the sliding groove restricts the rotation of the connecting rod, the fourth screw rod is rotated so that the connecting rod moves downward along with the rotation of the fourth screw rod until the blade cuts the coating on the surface of the sample.

[0020] Through the above arrangement, the device can be applied to samples of various thicknesses, thereby improving the practicability of the utility model.

[0021] In the utility model, a groove is provided on the top of the base, and the fixing mechanism includes a bidirectional screw and a limiting protrusion. The bidirectional screw is rotatably arranged in the groove, and two limiting protrusions are provided, which are symmetrically fitted on the positive and negative thread sections of the bidirectional screw, and the limiting protrusions are slidably abutted against the side walls of the groove.

[0022] The principle and effect of this technical solution:

[0023] Place the sample on the top of the base and make it between the two limit bumps. Since the groove limits the rotation of the limit bump, rotate the bidirectional screw to make the two limit bumps move toward each other at the same time until the two limit bumps clamp the sample respectively.

[0024] Through the above arrangement, the purpose of enabling the fixing mechanism to fix the sample is achieved, thereby improving the practicality of the utility model.

[0025] In the utility model, two through holes are provided on the top of the base, a pin rod is slidably inserted into the through holes, a tension spring is sleeved outside the pin rod and below the base, the two ends of the tension spring are respectively connected to the bottom of the base and the bottom of the pin rod, the axis of the two through holes and the axis of the mounting seat are perpendicular to each other, a connecting plate is fixedly provided on the outer wall of the mounting seat, and a socket matching the pin rod is provided on the top of the connecting plate.

[0026] The principle and effect of this technical solution:

[0027] In the initial state, the socket is aligned with one of the through holes, and the top of the pin rod in the through hole is inserted into the socket. After sliding the slider along the slide bar, pull the pin rod downward until the upper edge of the pin rod is lower than the lower edge of the connecting plate, rotate the mounting seat, and then pull the other pin rod downward until the upper edge of the other pin rod is lower than the lower edge of the connecting plate. Continue to rotate the mounting seat until the socket is aligned with the other through hole, release the other pin rod, and the other pin rod moves upward under the action of the tension spring until the top of the other pin rod is inserted into the socket.

[0028] Through the above arrangement, on the one hand, it is possible to prevent the mounting base from rotating during the sliding of the slider, and on the other hand, it is possible to ensure that the rotation angle of the mounting base is 90°, thereby ensuring the accuracy of the detection result.

[0045] The specific implementation process is as follows:

[0046] Place the sample 70 on the top of the base 10 and fix it by a fixing mechanism. According to the coating thickness and substrate type of the sample 70, place the first partition 53 or the second partition 63 between two adjacent tool handles 421 to adjust the spacing between two adjacent blades 42. Rotate the first screw 412 to make the limit block 43 press against each tool handle 421. Then lower the mounting block 41 to make the blade 42 abut against the sample 70. Slide the slider 32 along the slide bar 31 to draw at least 6 cutting lines on the surface of the sample 70. Then rotate the mounting seat 30 90° and slide the slider 32 again to slide out a grid on the surface of the sample 70.

[0047] In the initial state, the limit block 43 pushes the tool handles 421 to abut against each other, the first guide bevels on the left end of the tool handle 421 and the right end of the first partition plate 53 fit together, and the spacing between the blades 42 is t1, which is the first use state; the first screw rod 412 is rotated in the opposite direction to move the limit block 43 away from the tool handle 421, and then the second screw rod 52 is rotated to push the first U-shaped frame 51 and each first partition plate 53 close to the first screw rod 412. In this process, the first partition plate 53 is displaced in the front-to-back direction at the same time under the action of the first guide bevels until each first partition plate 53 and each tool handle 421 are arranged alternately, and the limit block 43 is driven to press against the tool again. Handle 421, at this time, the spacing between each blade 42 is t1+t2=2×t1, and the second guide bevels at the right end of the handle 421 and the left end of the second partition 63 are arranged alternately, which is the second use state; after the limit block 43 is moved away from the handle 421 again, the third screw 62 is rotated to push the second U-shaped frame 61 and each second partition 63 close to the first screw 412.

At this time, the spacing between each blade 42 is t1+t3=3×t1, which is the third use state.

[0048] Since the sliding groove 321 limits the rotation of the connecting rod 413 , the fourth screw rod 33 is rotated, so that the connecting rod 413 moves downward along with the rotation of the fourth screw rod 33 until the blade 42 cuts the coating on the surface of the sample 70 .

[0049] The sample 70 is placed on the top of the base 10 and located between the two limiting protrusions 22. Since the groove 11 limits the rotation of the limiting protrusion 22, the bidirectional screw 21 is rotated to move the two limiting protrusions 22 toward each other at the same time until the two limiting protrusions 22 clamp the sample 70 respectively.

[0050] In the initial state, the socket 341 is aligned with one of the through holes 12, and the top of the pin rod 121 in the through hole 12 is inserted into the socket 341. After sliding the slider 32 along the slide bar 31, pull the pin rod 121 downward until the upper edge of the pin rod 121 is lower than the lower edge of the connecting plate 34, rotate the mounting seat 30, and then pull the other pin rod 121 downward until the upper edge of the other pin rod 121 is lower than the lower edge of the connecting plate 34, continue to rotate the mounting seat 30 until the socket 341 is aligned with the other through hole 12, release the other pin rod 121, and the other pin rod 121 moves upward under the action of the tension spring 122 until the top of the other pin rod 121 is inserted into the socket 341.
