TECHNICAL FIELD

[0001] The present application relates to the technical field of thickness detection, and particularly relates to a coating thickness detection device. BACKGROUND

[0002] When rubber counterweight blocks are prepared, a layer of DLC (diamond-like carbon) coating needs to be coated on the surface of the rubber counterweight block mold. The DLC coating can improve the wear resistance of the surface of the rubber counterweight block mold and increase the service life of the rubber counterweight block mold. Therefore, the thickness of the DLC coating of the rubber counterweight block mold needs to be detected regularly to ensure the uniformity and integrity of the DLC coating.

[0003] The existing coating thickness detection device, such as the coating thickness detection device disclosed in Chinese patent application CN110567415A, detects the thickness of a coating at one collection point each time.

[0012] As a further scheme of the present application: a fixed oil lever is fixedly connected to the inside of the power transmission box, a sliding oil lever is connected to the bottom end of the fixed oil lever through a hose, and a sliding limiting rod is connected to one side of the sliding oil lever.

[0013] As a further scheme of the present application: a return spring is fixedly connected to the top end of the detection probe, a pulling rod is fixedly connected to the position corresponding to the inner side of the return spring at the top end of the detection probe, a pushing piston is fixedly connected to the top end of the pulling rod, and the pushing piston is matched with the inner cavity of the sliding oil lever.

[0018] In the present application, the movement of the power transmission box is continuous, so when the bottom end of the detection probe contacts the coating on the top surface of the sample to be measured, the detection probe will stay on the top surface of the sample to be measured due to friction, and the power transmission box will continue to move. When the detection probe collects the thickness of the coating on the top surface of the sample to be measured, the detection probe will automatically rise and be separated from the top surface of the sample to be measured. At this time, the buffer seat is automatically restored to the initial position on the buffer slide rail under the action of the elastic connecting rod. This can ensure that the detection probe can stay long enough when detecting the thickness of the coating on the top surface of the sample to be measured. On the one hand, it ensures the accuracy of the detection probe collecting the thickness of the coating, and on the other hand, it prevents the detection probe from moving on the surface of the coating due to friction, which can cause damage to the coating. Furthermore, the present application can directly use the multi-point thickness data to objectively quantify and evaluate the uniformity of the coating in the process quality control of the thickness measurement link, thereby improving the inspection consistency and reducing the re-inspection rate.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] As one embodiment of the present application, as shown in Figures 1-14 The coating thickness detection device includes a device base 1, a control panel 2 is installed on one side of the top surface of the device base 1, and the control panel 2 can be integrated with control buttons, a display screen, and an eddy current thickness gauge. The specific arrangement position of the control buttons, the display screen, and the eddy current thickness gauge is adaptively adjusted by a person skilled in the art according to the size of the control panel 2. Since the eddy current thickness gauge already contains buttons and a display screen, the control panel 2 can also be replaced by the eddy current thickness gauge. A clamping mechanism 3 is arranged on the other side of the top surface of the device base 1, and a thickness detection mechanism 4 is arranged at the middle position of the top surface of the device base 1. The thickness detection mechanism 4 moves on the surface of a sample 5 to be detected, as shown in Figure 1 Generally, the detection surface of the sample 5 to be detected faces the thickness detection mechanism 4, and the thickness detection mechanism 4 moves along the detection surface. That is, when the thickness detection mechanism 4 moves along the surface of the sample 5 to be detected, the array point thickness is automatically collected. The array point thickness refers to the coating thickness at different positions on the surface of the sample 5 to be detected. The average thickness of the surface of the sample 5 to be detected is generated based on the array point thickness. The coating thickness of the sample 5 to be detected calculated based on the array point thickness is more accurate. When detecting the coating of a rubber counterweight block mold, the rubber counterweight block mold can be fixed on the device base 1 by the clamping mechanism 3. The coating of the rubber counterweight block mold generally adopts a DLC coating (diamond-like carbon film). The thickness detection mechanism 4 can detect the thickness of the DLC coating on the rubber counterweight block mold, so as to ensure the uniformity and surface integrity of the DLC coating on the rubber counterweight block mold and avoid the exposure of the base material of the rubber counterweight block mold to accelerate the corrosion of the rubber counterweight block mold. The thickness detection mechanism 4 collects the thickness of the DLC coating on the rubber counterweight block mold by eddy current. Specifically, an electromagnetic field is generated in the measuring head coil by a high-frequency alternating current signal. When the measuring head is close to the rubber counterweight block mold, an eddy current is formed in the rubber counterweight block mold. The closer the measuring head is to the conductive base, the larger the eddy current and the reflection impedance. This feedback effect represents the distance between the measuring head and the rubber counterweight block mold, that is, the thickness of the non-conductive coating (DLC coating) on the rubber counterweight block mold.

[0037] It should be noted that the clamping mechanism 3 comprises a clamping support plate 31, a screw rod 32 is installed at the inner center position of the clamping support plate 31 through a rotating shaft, a clamping limiting plate 33 is installed on the outer side of the screw rod 32, a nut matched with the screw rod 32 is installed at the inner position close to the screw rod 32 of the clamping limiting plate 33, and the movement of the clamping limiting plate 33 on the top surface of the clamping support plate 31 can be realized by rotating the screw rod 32 and matching the nut installed in the inner part of the clamping limiting plate 33. After the sample to be measured 5 is placed on the top surface of the clamping support plate 31, the screw rod 32 can be rotated, and the rotation of the screw rod 32 can be in an electric mode or a manual mode, which is selected by the person skilled in the art according to the clamping force of the sample to be measured 5. After the sample to be measured 5 is fixed on the top surface of the clamping support plate 31 by the clamping limiting plate 33, the thickness of the coating on the sample to be measured 5 can be collected by the thickness detection mechanism 4;

[0038] Specifically, the thickness detection mechanism 4 moves on the sample to be measured 5 to collect the thickness of the coating. During the movement, the thickness detection mechanism 4 automatically collects the array point thickness on the sample to be measured 5. It should be noted that the array point thickness refers to the thickness of a plurality of detection points collected at equal intervals on the sample to be measured 5. Since the thickness detection mechanism 4 automatically collects, the efficiency of collecting the thickness of the coating on the sample to be measured 5 is greatly improved by the thickness detection mechanism 4. Then, the average thickness of the surface of the sample to be measured 5 can be generated based on the array point thickness. Specifically, the variance of the array point thickness is calculated, and the uniformity of the thickness of the coating on the sample to be measured 5 is determined according to the variance. If the variance of the array point thickness is too large, it indicates that the thickness of the coating on the sample to be measured 5 is not uniform enough. The person skilled in the art can polish or re-coat the coating on the sample to be measured 5 to ensure the uniformity of the coating on the sample to be measured 5.

[0039] A plane rectangular coordinate system can also be established based on the array point positions collected by the thickness detection mechanism 4 on the sample to be measured 5. Then, a thickness threshold of the coating is preset. If the thickness of a certain collection point in the array point thickness is less than the thickness threshold, the collection point can be marked, which facilitates accurate maintenance of the coating on the sample to be measured 5 and improves the maintenance efficiency of the coating on the sample to be measured 5.

[0051] As an embodiment of the present application, as shown in Figure 9 and Figure 12 As shown, the inner top surface of the power transmission box 441 is installed with a driving motor 4414, the output shaft of the driving motor 4414 is installed with a driving worm 4415, one side of the driving worm 4415 is engaged with a driving worm wheel 4416, the top surface of the driving worm wheel 4416 is fixedly connected with the bottom surface of the longitudinal sliding block 442 through the power transmission box 441, and it should be noted that when the driving motor 4414 is turned on, the output shaft of the driving motor 4414 drives the driving worm 4415, since one side of the driving worm 4415 is engaged with the driving worm wheel 4416, the rotating driving worm 4415 drives the driving worm wheel 4416 to rotate, and the top surface of the driving worm wheel 4416 is fixedly connected with the bottom surface of the longitudinal sliding block 442 through the power transmission box 441, so that the power transmission box 441 can freely rotate along the horizontal direction on the bottom surface of the longitudinal sliding block 442, and the driving worm 4415 and the driving worm wheel 4416 have a self-locking effect, so that the angle of the power transmission box 441 in the horizontal direction on the bottom surface of the longitudinal sliding block 442 can be freely adjusted.

[0052] As one of the embodiments of the present application, the bottom surface of the power transmission box 441 is fixedly connected with a buffer frame 446, the inner side of the buffer frame 446 is provided with a slidable buffer seat 447, the detection probe 45 is arranged inside the buffer seat 447 and slides synchronously with the buffer seat 447, and it needs to be noted that the buffer frame 446 is fixed to the bottom surface of the power transmission box 441, so when the power transmission box 441 moves, the buffer frame 446 will move synchronously with the power transmission box 441, and the buffer seat 447 is provided with a buffer sliding groove 4472 on both sides, and the inner side of the buffer frame 446 is fixedly connected with a buffer sliding rail 4462, so that the buffer sliding groove 4472 is matched with the buffer sliding rail 4462, and thus the buffer seat 447 can slide freely along the direction of the buffer sliding rail 4462 through the cooperation of the buffer sliding groove 4472 and the buffer sliding rail 4462;

[0053] The inner side of the buffer frame 446 is also fixedly connected with an elastic connecting rod 4461, and the buffer seat 447 is provided with a buffer circular hole 4471 matched with the elastic connecting rod 4461 near the position of one side of the buffer seat 447, and the elastic connecting rod 4461 is fixedly connected with the inner side end of the buffer circular hole 4471, and the elastic connecting rod 4461 can be a spring or a mechanism providing elastic force, since the movement of the power transmission box 441 is continuous, when the bottom end of the detection probe 45 contacts the coating on the top surface of the sample 5 to be detected, the detection probe 45 will stay on the top surface of the sample 5 to be detected due to friction, and the power transmission box 441 will continue to move, when the detection probe 45 collects the thickness of the coating on the top surface of the sample 5 to be detected, the detection probe 45 will automatically rise and separate from the top surface of the sample 5 to be detected, at this time, the buffer seat 447 automatically returns to the initial position on the buffer sliding rail 4462 under the action of the elastic connecting rod 4461, so that the detection probe 45 can stay for a sufficient time when detecting the thickness of the coating on the top surface of the sample 5 to be detected, on the one hand, to ensure the accuracy of the detection probe 45 in collecting the thickness of the coating, and on the other hand, to prevent the detection probe 45 from moving on the surface of the coating due to friction and causing damage to the coating;

[0054] In addition, it needs to be noted that one side of the sliding oil rod 4412 is connected with a sliding limiting rod 4413, the sliding limiting rod 4413 is composed of two limiting rods which are sleeved with each other, one limiting rod is fixedly connected with the side surface of the sliding oil rod 4412, and the other limiting rod is fixedly connected with the inner side surface of the power transmission box 441, when the buffer seat 447 moves relative to the power transmission box 441, the sliding limiting rod 4413 will not affect the position of the sliding oil rod 4412 in the horizontal direction, but will limit the position of the sliding oil rod 4412 in the vertical direction, so as to ensure that the sliding oil rod 4412 can drive the detection probe 45 by pulling the pushing piston 453 and the pulling rod 452 to control the detection probe 45 to move up and down;

[0055] When the thickness detecting mechanism 4 collects the array point thickness of the top surface coating of the sample 5 to be detected by moving, the orientation of the buffer holder 446 and the buffer seat 447 needs to be controlled to ensure that the orientation of the buffer holder 446 and the buffer seat 447 is consistent with the moving collection direction of the thickness detecting mechanism 4, and the orientation of the buffer holder 446 and the buffer seat 447 is adjusted by the driving worm 4415 and the driving worm wheel 4416, which is not described herein.
