Description

Technical Field

[0001] This utility model relates to the field of precision measuring instrument technology, and in particular to a coating thickness measuring device for electroplating. Background Technology

[0002] Electroplating is widely used in industries such as machinery manufacturing and electronics to improve the wear resistance, corrosion resistance, and aesthetics of parts. Coating thickness is a key indicator of electroplating quality; therefore, accurate measurement of coating thickness is crucial. Currently, commercially available portable coating thickness gauges typically use a handheld main unit with a single contact probe for measurement.

[0003] However, in actual electroplating processes, the shapes of workpieces to be measured vary widely, ranging from regular flat plates and cylinders to complex irregular curved surfaces. Existing thickness gauge probes are mostly flat-headed designs with a fixed shape. When facing cylindrical surfaces with large curvature or uneven, irregular surfaces, the probes struggle to maintain a perpendicular fit, leading to large fluctuations in measurement data and inconsistent accuracy. Furthermore, when performing long-term, multi-point measurements with existing handheld thickness gauges, operators often need to hold the workpiece in one hand and the probe in the other, leaving the main unit lying flat on a cluttered workbench or hanging on their person. This not only makes it difficult to adjust to the optimal reading angle but also increases the risk of the main unit falling and being damaged due to cable entanglement. While some high-end equipment comes with independent stands, these stands are inconvenient to carry and cumbersome to adjust, failing to meet the needs of rapid on-site operations.

[0004] Therefore, this utility model proposes a coating thickness measuring device for electroplating to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a coating thickness measuring device for electroplating processing, which aims to improve the existing technology of coating thickness measuring devices for electroplating processing, which have problems such as the single probe being difficult to adapt to complex-shaped workpieces, resulting in low measurement accuracy, and the lack of a portable and stable support and adjustment structure for the main unit, resulting in inconvenience in on-site reading and difficulty in storing accessories.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coating thickness measuring device for electroplating, comprising: a detection host, a transmission line, a detection handle, a support assembly, and an adaptation assembly; the transmission line connects the detection host and the detection handle;

[0007] The support assembly includes a friction block fixed to the outer wall of the detection host, a sliding support frame slidably sleeved on the outer wall of the friction block, and a retaining plate. The outer wall of the sliding support frame is provided with a fixing groove and a support groove. The retaining plate can pass through the fixing groove or the support groove and extend into the interior of the detection host to limit the sliding support frame.

[0008] Furthermore, the adaptation component includes an upper detection magnet disposed inside the detection handle, and a set of replaceable detection heads, the detection heads including a cylindrical detection head, an irregular detection head, and a planar detection head; each of the cylindrical detection head, the irregular detection head, and the planar detection head is provided with a lower detection magnet; when the detection handle is connected to any of the detection heads, the upper detection magnet and the lower detection magnet are magnetically attracted to each other;

[0009] Preferably, the sliding support frame and the friction block maintain a stable relative position through friction. When the card plate is inserted into the fixing slot and the inside of the detection host, the sliding support frame is fixed in the storage state. When the card plate is inserted into the support slot and the inside of the detection host, the sliding support frame is fixed in the support state. At this time, the sliding support frame contacts the ground to tilt and support the detection host. Through the cooperation of the card plate with different slots, the support angle of the host can be quickly switched.

[0010] Preferably, the outer wall of the detection host is fixed with a first support frame for storing the cylindrical detection head. By providing a dedicated support frame on the side of the host, the cylindrical detection head can be easily carried and accessed.

[0011] Preferably, the first support frame is provided with a support magnet inside. When the cylindrical detection head is inserted into the first support frame, the detection magnet inside the cylindrical detection head is magnetically attracted to the support magnet. By using the magnetic attraction principle, the stability of the cylindrical detection head during storage is ensured, and accidental drop is prevented.

[0012] Preferably, the outer wall of the detection host is fixed with a second support frame for storing the irregular detection head, providing dedicated storage space for the irregular detection head and further improving accessory management;

[0013] Preferably, the irregular detection head has multiple small cylindrical detectors slidably connected inside. This split internal structure design is the basis for achieving adaptive fitting.

[0014] Preferably, the plurality of small cylindrical detectors are configured to slide inside the irregular detection head when testing irregular objects to adapt to the surface of the irregular object. Through the independent sliding of each sub-probe, the complex contour of the object under test can be automatically fitted, significantly improving measurement accuracy.

[0015] Preferably, the fixing groove and the supporting groove are spaced apart along the sliding direction of the sliding support frame. This reasonable groove spacing design ensures that the support structure has sufficient lever arm and stability when deployed.

[0016] Preferably, the detection handle is fixedly connected to one end of the transmission line, and the other end of the transmission line is connected to the detection host. The surface of the detection host is used to display the detected coating thickness data, thus clarifying the signal transmission path and data display method, and constituting a complete measurement system.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of poor measurement fit and low accuracy caused by the single probe shape in existing coating thickness gauges when dealing with electroplated parts of various shapes, by setting up adaptive components and detachable and replaceable detection heads. Specifically, by using a magnetic connection method, operators can quickly change to planar detection heads, cylindrical detection heads, or irregular detection heads according to the shape of the object being measured. In particular, the V-shaped end face of the cylindrical detection head and the adaptive telescopic array design of the irregular detection head ensure a tight fit between the probe and the surface being measured, thereby achieving the technical effect of improving measurement accuracy and the applicability of the device.

[0019] 2. This utility model solves the problems of traditional handheld thickness gauges lacking stable support and having inconvenient data reading angles during on-site operations by setting a support assembly including a sliding support frame, friction blocks, and a locking plate on the outer wall of the detection host. Specifically, by pulling the locking plate to release the limit, sliding the sliding support frame out, and then using the locking plate to re-insert into the support slot to lock it, a stable inclined support structure can be quickly constructed on-site, achieving the technical effects of freeing the operator's hands, facilitating real-time observation of screen data, and improving the convenience of on-site operations.

[0020] 3. This utility model solves the problem of easy loss and disorganized storage of testing device accessories in industrial settings by integrating a first support frame and a second support frame with magnetic attraction function on the outer wall of the testing host. Specifically, by utilizing the magnetic attraction between the inherent detection magnet inside each testing head and the pre-set support magnet inside the support frame, idle testing heads can be firmly attracted and stored on the side of the host, achieving the technical effects of readily available accessories, neat and orderly storage, and prevention of accidental drop and loss.

[0028] 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.

[0029] Reference Figures 1-5 This utility model provides an embodiment of a coating thickness measuring device for electroplating, including a detection host 1 and a detection handle 3 that is connected to the detection host 1 via a transmission line 2 for data interaction. In order to achieve stable support and viewing angle adjustment of the device under different working environments, a support component 4 is provided on the outer wall of the detection host 1. In order to meet the requirements for accurate measurement of flat, curved and irregular surfaces, an adaptable component 5 that can be quickly disassembled and replaced is provided at the front end of the detection handle 3. The detection host 1 serves as the core control and display carrier, and a display screen is provided on its surface to display the coating thickness value in real time. One end of the transmission line 2 is fixedly connected to the tail of the detection handle 3, and the other end of the transmission line 2 is fixedly connected to the side port of the detection host 1. The stability and anti-interference ability of the detection data transmission are ensured by the wired connection.

[0030] The support component 4, as a key mechanism for adjusting the posture of the detection host 1, mainly consists of a friction block 402 fixedly connected to the outer wall of the detection host 1, a sliding support frame 401 slidably sleeved on the outer wall of the friction block 402, and a locking plate 404 for locking the position. The friction block 402 is tightly attached to the outer surface of the detection host 1 by bolts or strong adhesive, providing a stable installation base for the sliding support frame 401. The inner wall of the sliding support frame 401 is tightly attached to the outer wall of the friction block 402 and forms a sliding connection. There is a certain damping friction between the two, which makes it easy to adjust the position in the unlocked state and not easy to slip freely. The locking plate 404, as a limiting and locking component, is transversely inserted between the sliding support frame 401 and the detection host 1 to switch and lock the sliding support frame 401 between the storage state and the support state.

[0031] The adaptation component 5 endows the detection handle 3 with diverse detection capabilities. It includes an upper detection magnet 504 embedded in the front end of the detection handle 3, and a set of replaceable detection heads customized according to the shape of the workpiece. The set of detection heads specifically includes a flat detection head 506 for measuring conventional flat surfaces, a cylindrical detection head 501 for measuring pipes or shaft parts, and an irregular detection head 502 for measuring complex uneven surfaces. The connecting end faces of the flat detection head 506, the cylindrical detection head 501, and the irregular detection head 502 are all fixedly embedded with a lower detection magnet 505. When the operator brings the selected detection head close to the front end of the detection handle 3, the strong magnetic attraction between the upper detection magnet 504 and the lower detection magnet 505 can instantly attract and fix the detection head to the detection handle 3, realizing mechanical connection and docking positioning at the same time, ensuring that the measurement signal can be accurately transmitted to the detection host 1 for processing.

[0032] The friction block 402 serves as a connecting base, with one end firmly fixed to the central area of ​​the outer wall of the detection host 1. The outer surface of the friction block 402 is frosted or covered with a high friction coefficient material to provide suitable sliding damping. The sliding support frame 401 is fitted around the friction block 402, and the inner wall size of the sliding support frame 401 is precisely matched with the outer wall size of the friction block 402, so that the sliding support frame 401 can be reciprocated and adjusted along the length of the friction block 402.

[0033] To achieve precise locking of the sliding support frame 401 at different positions, two key limiting slots are spaced apart on the outer wall of the sliding support frame 401 along its sliding trajectory: a fixing slot 403 near the inner side and a support slot 405 near the outer side. Both slots penetrate the wall thickness of the sliding support frame 401. Furthermore, a positioning blind hole or slot structure is reserved on the side wall of the outer casing of the detection host 1 corresponding to the mounting area of ​​the friction block 402 for the insertion of the end of the locking plate 404. The locking plate 404, as a key component for performing the locking action, has its entire... The body is L-shaped to facilitate hand gripping and operation. The size of the insertion end of the card plate 404 matches the diameter of the hole in the fixing groove 403 and the support groove 405. In the storage state, the sliding support outer frame 401 is fully retracted and fits against the side of the detection host 1. At this time, the fixing groove 403 is aligned with the positioning hole on the detection host 1. The card plate 404 is passed through the fixing groove 403 in sequence and deeply inserted into the detection host 1. The mechanical blocking of the card plate 404 restricts the movement of the sliding support outer frame 401, thereby stably locking the sliding support outer frame 401 in the storage position.

[0034] When it is necessary to tilt the support of the detection host 1 to facilitate data observation, the operator must first pull the card plate 404 outward to disengage it from the inside of the detection host 1 and the fixing groove 403, thereby releasing the limiting lock on the sliding support outer frame 401. Then, pull the sliding support outer frame 401 outward to allow it to slide smoothly on the outer wall of the friction block 402. When the sliding support outer frame 401 moves to the outermost limit position, the support groove 405 moves to the position aligned with the positioning hole on the detection host 1. At this time, insert the card plate 404 into the support groove 405 again and push it deeper into the detection host 1 to firmly lock the sliding support outer frame 401 in the extended support state. With the bottom edge of the extended sliding support outer frame 401 contacting the ground or workbench, the stability of the support structure is maintained under the combined action of the limiting effect of the card plate 404 and the friction force between the friction block 402 and the sliding support outer frame 401, thus forming a stable triangular support structure, allowing the detection host 1 to present an easy-to-read tilt angle.

[0035] In addition, for the storage and management of multiple detection heads, the outer wall of the detection host 1 is also specially fixedly connected with a first support frame 503 for storing cylindrical detection heads 501 and a second support frame 507 for storing irregular detection heads 502. The bottom of the inner part of the first support frame 503 is pre-embedded or glued with a support magnet 508. When the cylindrical detection head 501 is idle and inserted into the first support frame 503, the detection magnet 505 inside the cylindrical detection head 501 will magnetically attract with the support magnet 508, thereby firmly attracting the cylindrical detection head 501 in the storage position and preventing it from being accidentally dropped or lost during transportation or movement. The inner cavity shape of the second support frame 507 is designed to conform to the outer contour of the irregular detection head 502, ensuring that the irregular detection head 502 can be tightly embedded in it for storage.

[0036] As a preferred implementation method for complex surface detection, the irregular detection head 502 adopts a split adaptive contact structure design. The irregular detection head 502 has several independent and parallel guide channels inside. Each guide channel is precisely slidably connected to a small cylindrical detector. The multiple small cylindrical detectors do not interfere with each other and can independently reciprocate along the axial direction of the guide channel. When the irregular detection head 502 is pressed on the uneven surface of the object to be measured, the small cylindrical detectors are squeezed by the difference in surface height and produce different degrees of axial displacement, so that the end contours of the multiple small cylindrical detectors automatically fit the surface shape of the object to be measured, realizing multi-point synchronous bonding and thickness data acquisition of irregular surfaces.

[0037] To ensure the stability and consistency of the detection signal when transmitted through the magnetic interface, the upper detection magnet 504 is embedded at the geometric center of the end face of the detection handle 3, and its outer surface is flush with the end face of the detection handle 3 to prevent mechanical interference. Correspondingly, the center of the connection end face of the cylindrical detection head 501, the irregular detection head 502 and the planar detection head 506 are all provided with mounting grooves that match the size of the upper detection magnet 504. The lower detection magnet 505 is interference-fitted and fixed inside the mounting groove. This center-aligned magnetic layout can guide the detection head and the detection handle 3 to automatically correct the axial deviation at the moment of connection, ensuring the coaxiality of the two after connection.

[0038] To address the stability requirements of the support component 4 under different conditions, the fixing groove 403 and the support groove 405 are arranged at intervals along the sliding trajectory of the sliding support frame 401, and the distance between them is calculated to meet the travel requirements of the detection host 1 from 0 degrees to the preset optimal observation tilt angle. The fixing groove 403 is located at one end close to the bottom of the detection host 1, and the support groove 405 is located at one end far from the bottom of the detection host 1. When the card plate 404 is inserted into the support groove 405, the length of the extended sliding support frame 401 can just form a stable triangular support structure with the bottom edge of the detection host 1.

[0039] Working principle: When using this coating thickness measuring device for electroplating, the operator contacts the surface of the object to be measured with their respective detection heads to detect the electroplated coating. The detection signal is transmitted from the detection device to the detection host 1 in real time through the transmission line 2. After the internal circuit of the detection host 1 processes the signal, the detected coating thickness value is clearly displayed on the surface screen of the detection host 1 for the operator to read.

[0040] During use, to facilitate convenient support of the detection host 1 for optimal data viewing, the operator uses the support component 4 to adjust the posture of the detection host 1. First, pull the clamping plate 404 outward, so that the clamping plate 404 is completely disengaged from the fixing groove 403 on the outer wall of the sliding support frame 401 and the positioning hole inside the detection host 1, thereby removing the mechanical limitation on the sliding support frame 401. Since one end of the friction block 402 is fixed to the outer wall of the detection host 1, after the limitation on the sliding support frame 401 is removed, the operator pulls the sliding support frame 401 outward, so that the sliding support frame 401 is outside the friction block 402. The sliding support frame 401 slides smoothly along the preset trajectory on the wall. When the sliding support frame 401 slides to the outermost limit position, the card plate 404 is aligned and inserted into the support groove 405 opened on the outer wall of the sliding support frame 401 and goes deep into the detection host 1. The sliding support frame 401 is locked and fixed in the support position. At this time, under the combined action of the pin limiting action of the card plate 404 and the friction force between the friction block 402 and the sliding support frame 401, the sliding support frame 401 is stably kept in the extended support position, so that the detection host 1 is placed in an inclined state, so that the bottom end of the sliding support frame 401 contacts the ground, and the detection host 1 is stably supported.

[0041] When measuring the coating thickness of objects of different shapes, the operator selects the appropriate detection head through the adaptation component 5 to ensure measurement accuracy. A detection handle 3 is fixedly connected to one end of the transmission line 2. A detection magnet 504 is set inside the detection handle 3. When the detection handle 3 is connected to each selected detection head, the detection magnet 504 inside the detection handle 3 and the detection magnet 505 inside each detection head are instantly magnetically attracted together, thereby firmly connecting the detection head and the detection handle 3 and realizing signal conduction. When measuring the coating thickness of a planar object, a planar detection head 506 is selected and installed on the detection handle 3 for detection. When measuring the coating thickness of a cylindrical object, a cylindrical detection head 501 is selected for detection. The end face shape of the cylindrical detection head 501 can fit the cylindrical surface, thus enabling accurate detection.

[0042] When the cylindrical detection head 501 is not in use, it is stored in the outer wall of the detection host 1 by the first support frame 503 fixed to the outer wall of the detection host 1. Since the first support frame 503 has a support magnet 508 and the cylindrical detection head 501 has a detection magnet 505, when the cylindrical detection head 501 is inserted into the first support frame 503 for storage, the detection magnet 505 and the support magnet 508 are magnetically attracted together, thus storing it stably and preventing it from falling. When measuring the coating thickness of irregular objects, the irregular detection head 502 is used for detection. Multiple small cylindrical detectors are slidably connected inside the irregular detection head 502. When detecting irregular objects, the multiple small cylindrical detectors slide independently inside the irregular detection head 502 under force, thus automatically adapting to the surface contour of the irregular object. When the irregular detection head 502 is not in use, it is inserted into the second support frame 507 fixed to the outer wall of the detection host 1 for storage.
