Description

Technical Field

[0001] This utility model relates to the field of thickness gauge technology, specifically a self-correcting coating thickness gauge. Background Technology

[0002] In the production and quality inspection of stainless steel strips for automotive trim, coating thickness gauges play a crucial role. Appropriate coating thickness ensures uniform color and consistent gloss, enhancing the overall aesthetics of the vehicle. Therefore, it is essential to guarantee consistent coating thickness across all trim strips to achieve product standardization and normalization. However, a drawback is that the cables of the coating thickness gauge tend to become tangled during storage. This necessitates untangling the cables before using the gauge, impacting its efficiency. To address this issue, existing technology (Chinese patent application number: 202321064006.6, authorized on September 29, 2023) discloses a coating thickness gauge. When using the gauge, it can be activated via a button on the casing. Then, the cables and the detection probe are moved to bring the probe into contact with the object being measured. The coating thickness gauge is touched, and then the display screen on its surface shows the test results, allowing the operator to understand the thickness of the coating on the object's surface. When the coating thickness gauge is not in use, the cable can be wound around the storage rack on the surface of the placement plate. Then, by operating the block, the first bolt is rotated, causing it to rotate inside the fixed plate with the round tube. The first bolt then moves the moving plate closer to the storage rack with the cable. At this time, the slider sliding inside the groove on the surface of the placement plate restricts the movement trajectory of the moving plate, and then the moving plate squeezes and fixes the cable on the surface of the storage rack, thus completing the cable storage and fixation. By using the storage device to store and fix the cable, it is possible to avoid the cable easily getting tangled when storing the coating thickness gauge, which would require untangling the tangled cable before using the coating thickness gauge, thus affecting the efficiency of the coating thickness gauge and improving its performance.

[0003] Existing technology uses a rotating first thread to press and fix the cable on the surface of the storage rack by a moving plate, thus completing the cable storage and fixation. However, it lacks a structure for storing the probe, which means that the probe may be placed randomly when not in use, easily getting tangled with the cable. It may also collide and rub against other tools or objects, causing scratches and wear on the probe surface. Furthermore, it lacks a function to clean the probe, resulting in impurities on the probe surface that affect the accuracy of the measurement data. Therefore, we have proposed a self-correcting coating thickness gauge that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a self-correcting coating thickness gauge to solve the problems mentioned in the background art, such as the lack of a structure for storing the probe, which makes the probe prone to being placed randomly when not in use, easily getting tangled with cables, and colliding and rubbing with other tools or objects, resulting in scratches and wear on the probe surface, and the lack of a function to clean the probe, resulting in impurities on the probe surface that affect the accuracy of the measurement data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-correcting coating thickness gauge, comprising a coating thickness gauge body and a cable, wherein a socket is installed on the right side of the top of the coating thickness gauge body, a probe is fixed to one end of the cable, and a plug is fixed to the end of the cable away from the probe; further comprising: a take-up frame and a fixing frame are fixedly connected to the right side of the coating thickness gauge body, and clamping plates are connected at equal intervals inside the take-up frame and the fixing frame, a connecting rod is fixed to the side of the clamping plate, and a third spring is installed inside the take-up frame and the fixing frame at the end of the connecting rod away from the clamping plate, and a locking block is provided at the bottom inside the fixing frame, and a cleaning sponge is installed on the top of the locking block.

[0006] Preferably, the cable and the take-up frame are connected by a snap-fit ​​connection, the plug and the socket are connected by a plug-in connection, and the probe and the fixing frame are connected by a snap-fit ​​connection.

[0007] Preferably, the clamping plate is arranged in an arc shape, and the clamping plate forms an elastic telescopic structure with the take-up frame and the fixing frame through the connecting rod and the third spring, and the top of the cleaning sponge is in contact with the bottom of the probe.

[0008] Preferably, a movable block is hinged to the lower front of the fixed frame, and a fixing magnet is fixed between the side of one end of the movable block and the right side of the card block.

[0009] Preferably, the movable block is arranged in an "L" shape, and the magnetic poles of the fixed magnet on the movable block and the fixed magnet on the card block are opposite.

[0010] Preferably, the socket has limit holes on both the left and right sides of its inner wall, and a driving block is connected to the inner wall of the limit hole. A second spring is installed between the outer side of the driving block and the limit hole. The plug has receiving grooves on both the left and right sides of its interior, and a limit block is slidably connected inside the receiving groove. A first spring is installed between the end of the limit block and the inner wall of the receiving groove.

[0011] Preferably, the driving block is slidably disposed inside the limiting hole, and the position of the limiting block corresponds to that of the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This self-correcting coating thickness gauge adopts a novel structural design, the specific details of which are as follows:

[0013] (1) After the test is completed, insert the probe into the fixed frame and insert the cable into the take-up rack. At this time, the clamping plate will be squeezed and moved. The third spring will be used to clamp and fix the cable and probe, so that the cable and probe can be stored, avoiding the cable from getting tangled together and affecting the use. At the same time, it keeps things neat and orderly, and is easy to operate and carry. It can also protect the probe from collisions and friction with other tools or objects, which may cause scratches and wear.

[0014] (2) When the probe is inserted into the fixed frame, its bottom will come into contact with the cleaning sponge. The cleaning sponge can remove impurities from the probe surface, ensuring that the probe is in close and uniform contact with the surface of the object being measured, thereby obtaining accurate measurement data. Furthermore, when it is necessary to remove the cleaning sponge for cleaning, simply rotate the movable block outward to separate the two fixed magnets, release the limit on the block, and then pull the cleaning sponge outward to remove it for cleaning, thereby improving the subsequent cleaning effect.

[0015] (3) By pressing the drive blocks on both sides, the two drive blocks move relative to each other and squeeze the limiting blocks, causing the two limiting blocks to move relative to each other and separate from the limiting holes, thus releasing the plug from its fixation. Then, simply pull the plug upward to separate it from the socket on the coating thickness gauge body and replace it, so that the probe can be quickly replaced according to different measurement needs. Furthermore, insert the plug on the new probe into the socket on the coating thickness gauge body, causing the two limiting blocks to move relative to each other under the pressure, and as the plug extends into the socket, the two limiting blocks move in opposite directions under the elastic force of the first spring and insert into the corresponding limiting holes, thus fixing the plug.

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: a self-correcting coating thickness gauge;

[0025] Example 1: To address the shortcomings of existing technologies, such as the lack of a structure for storing the probe 4, which allows the probe 4 to be left lying around when not in use, easily becoming tangled with the cable 3, and colliding and rubbing against other tools or objects, resulting in scratches and wear on the probe 4 surface, and the lack of a cleaning function for the probe 4, leading to impurities on the probe 4 surface affecting the accuracy of measurement data, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 6 As shown, the device includes a coating thickness gauge body 1 and a cable 3. A socket 2 is installed on the top right side of the coating thickness gauge body 1. A probe 4 is fixed to one end of the cable 3, and a plug 7 is fixed to the end of the cable 3 away from the probe 4. The device also includes a take-up frame 5 and a fixing frame 6 fixedly connected to the right side of the coating thickness gauge body 1. The cable 3 and the take-up frame 5 are connected by a snap-fit ​​connection, the plug 7 and the socket 2 are connected by a plug-in connection, and the probe 4 and the fixing frame 6 are connected by a snap-fit ​​connection. Clamping plates 16 are connected at equal intervals inside the take-up frame 5 and the fixing frame 6. A connecting rod 17 is fixed to the side of the clamping plate 16, and a third spring 18 is installed inside the take-up frame 5 and the fixing frame 6 at the end of the connecting rod 17 away from the clamping plate 16. The clamping plate 16 is arc-shaped, and the clamping plate 16 forms an elastic telescopic structure with the take-up frame 5 and the fixing frame 6 through the connecting rod 17 and the third spring 18.

[0026] During use, the inspector holds the coating thickness gauge body 1 in one hand and the probe 4 in the other, placing the probe 4 perpendicular to the surface of the stainless steel strip of the automotive trim, ensuring that the probe 4 is in close contact with the surface being measured to obtain accurate measurement values. These data are then transmitted to the intelligent algorithm module, which automatically adjusts the measurement hardware and software parameters according to the correction scheme, and then re-measures until the measurement results meet the accuracy standards. After the inspection is completed, the inspector inserts the probe 4 into the fixing frame 6 and the cable 3 into the cable take-up rack 5. At this time, the clamping plate 16 will be squeezed and moved, and the elasticity of the third spring 18 will clamp and fix the cable 3 and the probe 4, thus storing the cable 3 and the probe 4, preventing the cable 3 from getting tangled and affecting use, keeping them neat and orderly, and facilitating operation and carrying. It also protects the probe 4 from collisions or friction with other tools or objects, preventing scratches and wear.

[0027] Example 2: Unlike Example 1, this example utilizes a cleaning sponge 13 to automatically clean the probe 4 each time it is picked up or put away, thereby ensuring that the probe 4 makes close and uniform contact with the surface of the object being measured, thus obtaining accurate measurement data. See details for further information. Figure 2 As shown, a locking block 12 is provided at the bottom inside the fixed frame 6, and a cleaning sponge 13 is installed on the top of the locking block 12. The top of the cleaning sponge 13 is in contact with the bottom of the probe 4. A movable block 14 is hinged to the lower front of the fixed frame 6, and a fixing magnet 15 is fixed between the side of one end of the movable block 14 and the right side of the locking block 12. The movable block 14 is arranged in an "L" shape, and the magnetic poles of the fixing magnet 15 on the movable block 14 and the fixing magnet 15 on the locking block 12 are opposite to each other.

[0028] When the probe 4 is inserted into or removed from the fixed frame 6, its bottom will come into contact with the cleaning sponge 13. The cleaning sponge 13 can remove impurities from the surface of the probe 4, ensuring that the probe 4 is in close and uniform contact with the surface of the object being measured, thereby obtaining accurate measurement data. When it is necessary to remove the cleaning sponge 13 for cleaning, simply rotate the movable block 14 outward to separate the two fixed magnets 15, release the restriction on the locking block 12, and then pull the cleaning sponge 13 outward to remove it for cleaning, thus improving the subsequent cleaning effect.

[0029] Example 3: Unlike Example 2, this example allows for quick replacement of the probe 4 according to different measurement requirements by pressing the drive block 10. See details below. Figure 1 , Figure 4 and Figure 6As shown, limit holes are provided on both the left and right sides of the inner wall of the socket 2, and a drive block 10 is connected to the inner wall of the limit hole. A second spring 11 is installed between the outer side of the drive block 10 and the limit hole. A receiving groove is provided on both the left and right sides of the inside of the plug 7, and a limit block 8 is slidably connected inside the receiving groove. A first spring 9 is installed between the end of the limit block 8 and the inner wall of the receiving groove. The drive block 10 is slidably disposed inside the limit hole, and the position of the limit block 8 corresponds to that of the limit hole.

[0030] The inspector manually presses the two drive blocks 10 on both sides, causing them to move relative to each other and press the limiting block 8, causing it to move out of the limiting hole and press the first spring 9, thus releasing the plug 7 from its fixation. Then, simply pull the plug 7 upward to separate it from the socket 2 on the coating thickness gauge body 1 and replace it. This allows for quick replacement of the probe 4 according to different measurement needs. Then, the plug 7 on the new probe 4 is inserted into the socket 2 on the coating thickness gauge body 1, causing the two limiting blocks 8 to move relative to each other under the pressure and extend into the socket 2 as the plug 7 extends. At this time, the two limiting blocks 8 move in opposite directions under the elastic force of the first spring 9 and insert into the corresponding limiting hole, thus fixing the plug 7.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
