Description

Technical Field

[0001] This utility model relates to the field of detection technology, and more specifically, to an electroplating photoelectric detection device. Background Technology

[0002] In the production process of electroplated products, the inspection of the quality of the electroplated layer on the sidewalls is a crucial step after the product is finished. Currently, among the many electroplating inspection techniques, the most common is to directly use a laser emitter to inspect the sidewalls of the electroplated product. Since electroplated products typically have multiple sides, and the quality of the electroplated layer on each side has a significant impact on the overall performance and appearance of the product, theoretically, each side of the product needs to be inspected and analyzed individually to ensure a comprehensive and accurate assessment of the electroplated layer quality.

[0003] However, existing electroplating photoelectric detection devices have the following problems when in use:

[0004] In actual testing operations, traditional testing methods have revealed significant limitations. Because testing devices are often equipped with only a single laser emitter and a fixed detection angle, when inspecting electroplated products with complex, multi-faceted structures, the angle of the product needs to be manually adjusted multiple times after each side is inspected to ensure the next side to be inspected falls within the effective detection range of the laser emitter. This frequent angle adjustment is not only cumbersome, but also requires additional time for repositioning and calibrating the testing equipment each time to ensure accuracy. These intermediate steps inevitably lead to a significant increase in the overall time cost of the testing process, severely reducing testing efficiency.

[0005] This invention enables the product's sidewall to pass through the detector's detection area in a fixed position in a comprehensive and orderly manner by using a motor to drive the turntable to rotate and an electric telescopic rod to control the sliding of the slider on the slide rail. This eliminates the need for multiple complex angle adjustments, greatly shortening the detection cycle and improving detection efficiency. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide an electroplating photoelectric detection device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electroplating photoelectric detection device, comprising: a housing, a turntable rotatably mounted inside the housing, a slider slidably connected to the upper end of the turntable, detectors fixedly mounted at both the left and right ends inside the housing, a base fixedly mounted at the bottom inside the housing, a rotating groove formed at the upper end of the base, the turntable disposed inside the rotating groove, slide rails fixedly mounted on both the left and right sides of the upper end of the turntable, the slider slidably connected to the slide rails, and a limiting plate fixedly connected between the two slide rails, the limiting plate being disposed on the front and rear sides between the slide rails.

[0008] A further preferred embodiment: the front of the enclosure is provided with a protective door, and the front of the protective door is provided with a handle.

[0009] A further preferred embodiment: a motor is fixedly installed at the bottom of the turntable, a mounting base is fixedly installed at the bottom of the motor, and the output end of the motor is fixedly connected to the bottom of the turntable.

[0010] A further preferred embodiment: the slider has grooves on both the left and right sides of its bottom, the grooves are slidably connected to the slide rail, the upper end of the slider is fixedly mounted with a fixing plate, and the upper end of the fixing plate is surrounded by baffles.

[0011] A further preferred embodiment: The rear end of the slider is provided with an electric telescopic rod, the base end of the electric telescopic rod is fixedly installed on the housing, and the output end of the electric telescopic rod is movably connected to the rear end of the slider.

[0012] A further preferred embodiment: a transmitter is fixedly installed on the bottom inner side of the detector, and a receiver is fixedly installed above the transmitter.

[0013] Beneficial effects:

[0014] 1. By setting up a slider, slide rail and limit block, the slider slides smoothly on the slide rail, allowing the electroplating sample to be tested placed on the slider to be accurately displaced in the horizontal direction. When testing a longer sample, the electric telescopic rod drives the slider to move along the slide rail, which can gradually scan different parts of the sample to ensure that the entire surface is covered by the detector light and avoid omissions. The limit block plays a crucial role in protection and positioning. It limits the sliding range of the slider and prevents the slider from falling off the slide rail due to excessive movement, thus ensuring the stability of the detection process and the safety of the equipment.

[0015] 2. By incorporating baffles, when placing the electroplating sample to be tested, the baffles surround the upper part of the fixed plate, effectively fixing and positioning the sample. Since the turntable rotates and the slider may slide on the slide rail during the testing process, there is a certain amount of movement. The baffles can prevent the sample from shifting due to these movements, ensuring that the sample is always in a suitable testing position. This ensures that the light emitted by the detector can accurately illuminate the preset testing area of ​​the sample, thereby guaranteeing the accuracy and reliability of the testing data. Secondly, the baffles can protect the sample to a certain extent, preventing it from accidentally sliding into other parts of the chamber during the testing process and preventing it from colliding with moving parts inside the device (such as the turntable, slide rail, etc.), reducing the risk of sample surface damage and potential damage to the equipment caused by collisions.

[0016] 3. In summary, this electroplating photoelectric detection device, with its structure including a turntable, slide rail, slider, and detector, allows the turntable to rotate at a constant speed driven by a motor, enabling a comprehensive circumferential scan of the sample placed on the slider. The rotating groove design at the bottom ensures the stability and accuracy of the rotation process. The combination of the slide rail and slider provides linear movement of the sample in the horizontal direction. Especially for long samples or situations requiring precise detection of different parts, the electric telescopic rod controls the slider's movement on the slide rail, ensuring that each area of ​​the sample passes through the detector's detection area sequentially, greatly expanding the detection range and flexibility. The detector, as the core detection component, uses photoelectric conversion principles to accurately capture the light signal reflected from the sample surface. The signal processing unit then converts the light signal into an analyzable electrical signal, meeting diverse detection needs for electroplated products and improving detection efficiency.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-4 In this embodiment of the present invention, an electroplating photoelectric detection device includes: a housing 1, a turntable 2 rotatably mounted inside the housing 1, a slider 3 slidably connected to the upper end of the turntable 2, detectors 4 fixedly mounted at both the left and right ends inside the housing 1, a base 103 fixedly mounted at the bottom inside the housing 1, a rotating groove 104 formed at the upper end of the base 103, the turntable 2 disposed inside the rotating groove 104, slide rails 203 fixedly mounted on both the left and right sides of the upper end of the turntable 2, the slider 3 slidably connected to the slide rails 203, and a limit plate 204 fixedly connected between the two slide rails 203. Limiting plates 204 are positioned on the front and rear sides between slide rails 203. A protective door 101 is located on the front of the housing 1, with a handle 102 on its front. In use, the protective door 101 is opened using the handle 102, and the item to be tested is placed on the slider 3 connected to the turntable 2. The protective door 101 is then closed, the detector 4 is turned on, and the turntable 2 is rotated. The turntable 2 begins to rotate slowly and uniformly within the rotating groove 104. As the turntable 2 rotates, the sample on the slider 3 passes sequentially through the detection areas of the two detectors 4. The detectors 4 emit detection light that illuminates the surface of the electroplated sample, then receive the reflected light and convert the light signal into an electrical signal. The electrical signal converted by the detectors 4 is transmitted to the connected signal processing unit. The signal processing unit amplifies, filters, and performs analog-to-digital conversion on the electrical signal to extract feature information related to the electroplating sample, such as signal features corresponding to parameters like coating thickness, coating uniformity, and surface roughness. If the object to be detected is too long, the slider 3 slides on the slide rail 203 to ensure that the object is fully detected. During the sliding process, the limiting plate 204 restricts the bottom of the slider 3 to prevent it from sliding excessively. Then, the protective door 101 is opened to flip the object over, allowing the remaining undetected surfaces to be detected.

[0024] In this embodiment of the utility model, a motor 201 is fixedly installed at the bottom of the turntable 2, and a fixed base 202 is fixedly installed at the bottom of the motor 201. The output end of the motor 201 is fixedly connected to the bottom of the turntable 2. When the turntable 2 is rotated, the output end of the motor 201 drives the turntable 2 to rotate slowly and uniformly in the rotating groove 104, so that the objects to be detected on the turntable 2 can be fully detected.

[0025] In this embodiment of the utility model, slide grooves 301 are provided on both the left and right sides of the bottom of the slider 3. The slide grooves 301 are slidably connected to the slide rail 203. A fixing plate 302 is fixedly installed on the upper end of the slider 3. Baffles 303 are fixedly installed around the upper end of the fixing plate 302. An electric telescopic rod 304 is provided at the rear end of the slider 3. The base end of the electric telescopic rod 304 is fixedly installed on the housing 1. The output end of the electric telescopic rod 304 is movably connected to the rear end of the slider 3. When it is necessary to use the slide rail 203 to push the slider 3 to slide and detect within the housing 1, the slider 3 is first... Move to the innermost side of housing 1, then close the protective door 101. After that, the electric telescopic rod 304 pushes the slider 3 to slide on the slide rail 203. When the slider 3 reaches the outermost side of the slide rail 203, the bottom of the slider 3 is restricted by the limit plate 204 to prevent the slider 3 from sliding excessively. At this time, retract the output end of the electric telescopic rod 304 and rotate the turntable 2. As the turntable 2 rotates, the slide rail 203 also rotates, causing the slider 3 to return to the innermost side of housing 1. Then the electric telescopic rod 304 outputs again to push the slider 3 out for testing again.

[0026] In this embodiment of the invention, a transmitter 401 is fixedly installed on the bottom inner side of the detector 4, and a receiver 402 is fixedly installed above the transmitter 401. When detection begins, the transmitter 401, located at the bottom inner side of the detector 4, continuously emits light of a specific wavelength (selected according to the electroplating material and detection purpose, such as the visible or near-infrared light band commonly used for detecting metal plating) and intensity to irradiate the surface of the electroplated sample. The light is reflected on the sample surface, and a portion of the reflected light is received by the receiver 402 located above the transmitter 401. The receiver 402 converts the received optical signal into an electrical signal and transmits it in real time to the connected signal processing unit.

[0027] Working principle: Open the protective door 101, and move the slider 3 to the outermost starting position inside the housing 1 by operating the control button of the electric telescopic rod 304. This position should facilitate the operator in placing the electroplating sample and ensure that the sample will not collide or interfere with other components during placement. Carefully place the electroplating sample to be tested on the fixing plate 302 at the top of the slider 3. Use the baffles 303 around the fixing plate 302 to initially fix and position the sample to prevent displacement or shaking during subsequent testing. After placement, according to the shape and size of the sample and the requirements of the testing area, adjust the slider 3 to the innermost side of the housing 1 using the turntable 2. Then, fine-tune the electric telescopic rod 304 to precisely adjust the position of the slider 3 so that the sample is accurately within the detection optical path range of the two detectors 4, that is, ensure that the light emitted by the transmitter 401 can completely illuminate the sample surface and that the reflected light can be effectively received by the receiver 402. After adjustment, close the protective door 101 and start the motor 201. The motor 201 drives the turntable 2 to rotate at a constant speed within the rotating groove 104. The transmitter 401, located at the bottom of the inner side of the detector 4, continuously emits light of a specific wavelength (selected according to the electroplating material and detection purpose, such as the visible or near-infrared light band commonly used for detecting metal plating) and intensity onto the surface of the electroplated sample. The light is reflected on the sample surface, and the reflected light is received by the receiver 402 located above the transmitter 401. The receiver 402 converts the received light signal into an electrical signal and transmits it to the connected signal processing unit in real time. The signal processing unit performs a series of complex processing operations on the received electrical signal. If sliding detection is required, retract the output end of the electric telescopic rod 304 and move the slider 3 to the innermost side of the housing 1. Then, start the electric telescopic rod 304 to push the slider 3 to slide outward along the slide rail 203. During the sliding process, when the slider 3 reaches the outermost side of the slide rail 203, the bottom of the slider 3 is restricted by the limiting plate 204 to prevent the slider 3 from sliding excessively. At this point, retract the output end of the electric telescopic rod 304, stopping the slider 3 at its outermost position. Restart the motor 201 to rotate the turntable 2. As the turntable 2 rotates, the slide rail 203 also rotates, causing the slider 3 to return to the innermost side of the housing 1. Then, the electric telescopic rod 304 outputs again, pushing the slider 3 out for another test. This cycle continues until all areas of the sample along the slide rail direction have been tested. During each slide of the slider 3, the detector 4 continuously detects and transmits signals to the signal processing unit for data processing and analysis, obtaining relevant coating characteristic information of the sample at different locations. If multiple sides of the sample need to be tested, after completing the above testing process, open the protective door 101, carefully remove the electroplated sample with one side already tested, flip it over, and then place it back on the fixing plate 302 on the slider 3. Following the sample placement and positioning steps, readjust the sample position and close the protective door 101.Repeat the steps of turntable rotation detection and slide rail sliding detection (if necessary) to conduct a comprehensive inspection of the other side of the sample, and then determine and process the inspection results.
