Description

Technical Field

[0001] This utility model relates to the technical field of electroplating coating detection equipment, specifically a coating thickness detection device. Background Technology

[0002] The thickness of the electroplated layer directly affects its functionality. An excessively thin layer cannot effectively isolate the substrate from corrosive media, easily leading to substrate corrosion and failure. Insufficient thickness of the hard plating layer will cause rapid wear, exposing the substrate and shortening the component's lifespan. An excessively thick plating layer wastes precious metals (such as gold and palladium), significantly increasing production costs. Furthermore, an overly thick plating layer may cause cracks or peeling due to increased internal stress, thus reducing reliability. Therefore, it is necessary to test the thickness of the electroplated layer.

[0003] Existing technologies utilize X-ray fluorescence, magnetic methods, eddy current methods, optical interferometry, or beta-ray backscattering to perform non-destructive testing of coating thickness. However, these technologies lack a correction structure for the test piece. When testing tilted or irregularly shaped test pieces, these non-destructive testing methods are prone to errors, thus reducing the accuracy of coating thickness detection. Therefore, we propose a coating thickness detection device. Utility Model Content

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] A coating thickness detection device, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, it includes a base 1; a calibration mechanism 2 is connected to the base 1. The calibration mechanism 2 can calibrate the workpiece to be tested, so that the testing area is calibrated to a horizontal state, thereby reducing the testing error caused by the tilt of the workpiece to be tested.

[0028] Specifically, the calibration mechanism 2 includes a support base 201 connected to the middle of the base 1. The support base 201 supports the workpiece to be tested, thus ensuring its stability during the coating inspection process. A support rod 202 is connected to the bottom of the support base 201, and the structure of the support rod 202 supports the support base 201. A piston rod 203 is fixedly connected to the bottom of the support rod 202, and a piston cylinder 204 is sleeved on the outside of the piston rod 203. The piston rod 203 and the piston cylinder 204 cooperate with each other, and the piston rod 203 is driven by the pressure of the gas inside the piston cylinder 204, thereby driving the piston rod 203 to move up and down. There are four support rods 202, four piston rods 203, and four piston cylinders 204, and the four sets of support rods 202, four piston rods 203, and four piston cylinders 204 are respectively set at the four corners of the bottom of the support base 201. The four piston cylinders 204 are interconnected, and the angle of the support base 201 can be automatically corrected by the gas pressure inside the piston cylinder 204.

[0029] It is worth noting that a positioning groove 205 is provided at the top of the support rod 202, and a support ball 206 is connected inside the positioning groove 205. The support ball 206 is fixedly connected to the bottom of the support base 201. The structure of the positioning groove 205 corresponds to the structure of the support ball 206. The positioning groove 205 can accommodate the support ball 206, and the support ball 206 allows the support rod 202 to rotate in any direction at the bottom of the support base 201. This facilitates the angle adjustment of the support base 201 and the part to be tested on the support base 201.

[0030] Furthermore, a clamping spring 208 is fixedly connected to the top of the support base 201, and a clamping block 209 is fixedly connected to the end of the clamping spring 208. The clamping block 209 has a wedge-shaped structure. The clamping spring 208 can drive the clamping block 209 through its own elasticity, causing the clamping block 209 to move towards the workpiece to be tested, and the inclined surface of the wedge-shaped clamping block 209 provides a downward driving force for the workpiece to be tested. An anti-slip pad 210 is fixedly connected to the top of the support base 201. The anti-slip pad 210 can limit the movement of the workpiece to be tested.

[0031] Based on this, an air pump 207 is fixedly connected to the bottom of the base 1. The output end of the air pump 207 is connected to the piston cylinder 204 through a pipe. The air pump 207 can pump air into the piston cylinder 204, so that the piston cylinder 204 is filled with enough gas and the gas pressure pushes the piston rod 203.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on Embodiment 1, a detection mechanism 3 is connected to the base 1, and the detection mechanism 3 can perform coating thickness detection operation on the workpiece to be tested.

[0034] In this embodiment, the testing mechanism 3 includes a support 301 connected to one side of the base 1. A testing head 302 is connected to the inner side of the support 301. The support 301 supports the entire testing mechanism 3, and the testing head 302 on the inner side of the support 301 can test the coating of the workpiece. A positioning frame 303 is sleeved on the outer side of the testing head 302. The positioning frame 303 is fixedly connected to the support 301, and the positioning frame 303 corresponds to the support base 201. The positioning frame 303 can position the workpiece with irregular structure, thereby keeping the testing area of ​​the workpiece horizontal and improving the accuracy of coating testing.

[0035] In addition, a screw 304 is rotatably connected to the base 1, passing through the bracket 301. The screw 304 meshes with the bracket 301, driving the bracket 301 to adjust its height. A guide rod 305 is fixedly connected to the base 1, passing through the bracket 301 and guiding the bracket 301 to ensure smoother movement.

[0036] Based on this, an adjustment knob 306 is rotatably connected to the side of the base 1. A meshing linkage gear 307 is fixedly connected to the inner side of the adjustment knob 306 and the bottom end of the screw 304. The linkage gear 307 is a bevel gear. The adjustment knob 306 can drive the screw 304, and the linkage gear 307 can convert the horizontal driving force into the vertical driving force.

[0037] In use, the coating thickness detection device of this utility model first places the workpiece to be tested on the support base 201 and adjusts the clamping block 209 to clamp and fix the workpiece. Then, the adjustment knob 306 is rotated, which drives the screw 304 to rotate through the linkage gear 307. When the screw 304 rotates, it drives the bracket 301 to adjust its height until the bracket 301 is adjusted to the set position. Then, the air pump 207 is started and air is pumped into the piston cylinder 204. The gas pressure inside the piston cylinder 204 increases accordingly, and the air pressure pushes the piston rod 203 upward.

[0038] When inspecting a workpiece with a standard structure, the clamping spring 208 positions the workpiece at the center of the support 201 via the clamping block 209, and the center of gravity of the standard workpiece is at the center. Therefore, when the piston rod 203 pushes the support 201 upward, the four corners of the support 201 rise and fall at the same speed because the gas pressure inside the piston cylinder 204 is the same, keeping the support 201 and the workpiece in a horizontal state.

[0039] When inspecting workpieces with irregular structures, the clamping spring 208 positions the workpiece in the middle of the support base 201 via the clamping block 209, ensuring that the workpiece and the positioning frame 303 correspond to each other. Subsequently, driven by the gas pressure inside the piston cylinder 204, the support base 201 and the workpiece continue to rise. When one end of the workpiece contacts the bottom of the positioning frame 303, the movement of one side of the workpiece is restricted. At this time, the other side of the workpiece continues to rise under the drive of the piston cylinder 204, thereby rotating the workpiece and bringing the workpiece inspection area to a horizontal state, thus facilitating the inspection operation.

[0040] After the testing operation is completed, the air pump 207 extracts the gas inside the piston cylinder 204 and lowers the support 201 and the workpiece, making it easier to remove the workpiece.
