Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to detection equipment used in an electroplating production line. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on certain metal surfaces. It is a process that uses electrolysis to make a layer of metal film adhere to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] In order to ensure the quality of workpieces in the electroplating production line, the workpieces will be inspected after electroplating to check whether the appearance of the workpiece is damaged after electroplating and to detect the thickness of the film layer on the surface of the workpiece (judged by the color difference of the workpiece surface) to ensure that the electroplating quality of the workpiece meets the requirements.

[0004] Among many inspection methods, visual inspection is a more commonly used inspection method. Visual inspection refers to converting the captured target into an image signal through a machine vision device, transmitting it to a dedicated image processing system, and converting it into a digital signal based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then determines whether the electroplating quality of the workpiece meets the requirements.

[0005] Chinese patent CN111054657A discloses an electroplating parts inspection device, including an inspection box, a detection cavity is arranged in the inspection box, a No. 1 image processing device is fixedly arranged on the upper side wall of the inspection cavity, a No. 1 camera is fixedly arranged at the lower end of the No. 1 image processing device, a No. 2 image processing device is fixedly arranged on the lower side wall of the inspection cavity, and a No. 2 camera is fixedly arranged at the upper end of the No. 2 image processing device; the application is provided with an automatic loading and unloading mechanism, which can realize automatic loading and unloading of material trays, and uses an image processing system to inspect parts. The inspection has high accuracy and fast speed, and defective parts can be automatically removed. The application has a high degree of automation and simple operation, and is suitable for installation and use on a continuous electroplating production line.

[0006] When visual inspection is used to inspect workpieces, the workpieces need to remain relatively stable. However, in the electroplating production line, the workpieces move at a certain speed in the production line. Therefore, the workpieces may fluctuate to a certain extent when passing through the inspection equipment, resulting in inaccurate inspection results, which in turn affects the inspection equipment's judgment of the quality of the electroplated workpieces. At the same time, the distance between the visual inspection and the workpiece will also affect the inspection results. When the distance between the visual inspection and the workpiece is too far, the image processing system has a large processing capacity, takes a long time, and has low result accuracy. When the distance between the visual inspection and the workpiece is too close, the visual inspection range is limited. Summary of the invention

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figures 1 to 5As shown, the detection equipment for electroplating production line described in the utility model includes a detection terminal 1, specifically, the detection terminal 1 is used to detect the image signal of the detected workpiece; further, it includes a display terminal 2, the display terminal 2 is electrically connected to the detection terminal 1, specifically, the display terminal 2 displays the detection parameters and whether it is finally qualified, if qualified, it displays: qualified, if unqualified, it displays: unqualified. Further, it includes a control terminal, the control terminal is electrically connected to the detection terminal 1 and the display terminal 2, specifically, the control terminal reads all the detection data from the detection terminal 1, and determines whether the detection result is qualified according to the standard range value in the system setting, and outputs the detection data and the detection result in the display device. Furthermore, the detection terminal 1 includes a feed position 1a, a detection position 1b, a discharge position 1c and a limit mechanism 1d. The workpiece enters the detection terminal 1 through the feed position 1a. The detection position 1b is arranged between the feed position 1a and the discharge position 1c. The workpiece entering the detection terminal 1 enters the discharge position 1c through the detection position 1b. The detection position 1b is provided with a detection component 1b1. The detection component 1b1 is used to collect image signals of the detected workpiece. After collection, the workpiece leaves the detection terminal 1 through the discharge position 1c and enters the next process flow. The limit mechanism 1d is arranged between the feed position 1a and the discharge position 1c. Specifically, the limit mechanism 1d is used to limit the moving trajectory of the workpiece in the detection terminal 1, improve the stability of the workpiece in the moving process in the detection terminal 1, thereby reducing the fluctuation of the workpiece when passing through the detection equipment without affecting the quality of the workpiece, thereby ensuring the accuracy of the detection result, and then ensuring that the detection equipment accurately judges the quality of the electroplated workpiece.

[0032] refer to Figure 3 As shown, the detection component 1b1 includes a backlight panel 1b11 and a camera 1b12. The backlight panel 1b11 is arranged parallel to the moving direction of the workpiece in the detection terminal 1 and is located on one side of the workpiece; the camera 1b12 is arranged opposite to the backlight panel 1b11 and is located on the other side of the workpiece; the position between the backlight panel 1b11 and the camera 1b12 constitutes the above-mentioned detection position 1b, and when the workpiece passes through the detection position 1b, the camera 1b12 collects the image signal of the workpiece.

[0033] refer to Figure 3As shown, in order to improve the detection speed and detection accuracy and reduce the pixel points within the detection range of a single camera 1b12, the detection component 1b1 also includes a movable bracket 1b13, the movable bracket 1b13 is arranged opposite to the backlight plate 1b11, and the camera 1b12 is arranged on the movable bracket 1b13. The camera 1b12 approaches the backlight plate 1b11 through the movable bracket 1b13, thereby shortening the distance between the camera 1b12 and the workpiece, thereby reducing the pixel points within the detection range of the camera 1b12. The pixel points within the detection range can also be reduced to a certain extent by adjusting the focal length of the camera 1b12. Since the detection range of the camera 1b12 is reduced, in order not to affect the detection of the entire workpiece by the detection terminal 1, one or more cameras 1b12 can be set on the movable bracket 1b13 according to the size of the workpiece. When only the specified position of the workpiece needs to be detected, the specified position of the workpiece can be detected by adjusting the position of the camera 1b12 on the movable bracket 1b13.

[0034] refer to Figure 3 As shown, in order to improve the automatic control of the start and stop of the camera 1b12, the detection component 1b1 also includes a sensing switch 1b14. The sensing switch 1b14 is arranged between the feeding position 1a and the detection position 1b. The sensing switch 1b14 is electrically connected to the camera 1b12. When the sensing switch 1b14 detects and determines that a workpiece enters the detection position 1b, the sensing switch 1b14 starts the camera 1b12; when the sensing switch 1b14 detects and determines that no workpiece enters the detection position 1b, the sensing switch 1b14 turns off the camera 1b12.

[0035] refer to Figure 4 As shown, in order to limit the moving trajectory of the workpiece in the detection terminal 1 and improve the stability of the workpiece moving process in the detection terminal 1, the limiting mechanism 1d includes a rod seat 1d1 and a limiting rod 1d2. The two rod seats 1d1 are symmetrically arranged along the moving trajectory of the workpiece in the detection terminal 1 with the detection position 1b as the center, and the two limiting rods 1d2 are symmetrically arranged on the rod seat 1d1. The workpiece passes through the interval between the two limiting rods 1d2, and the limiting rod 1d2 contacts the workpiece, thereby limiting the moving trajectory of the workpiece in the detection terminal 1 and improving the stability of the workpiece moving process in the detection terminal 1. Therefore, the fluctuation of the workpiece when passing through the detection equipment is reduced without affecting the quality of the workpiece, thereby ensuring the accuracy of the detection result, and further ensuring that the detection equipment can accurately judge the quality of the electroplated workpiece.

[0036] When inspecting different workpieces, in order to make the limiting rod 1d2 contact with the workpiece without affecting the movement of the workpiece, the interval between the two limiting rods 1d2 needs to be adjusted.

[0037] Furthermore, the rod seat 1d1 is provided with a plurality of adjustment holes evenly distributed around the circumference, and the limit rod 1d2 can be installed in a suitable adjustment hole according to the thickness of different workpieces, so as to adjust the interval between the two limit rods 1d2. Furthermore, when the gap between the two limit rods 1d2 and the workpiece cannot be adjusted through the adjustment hole, the rod seat 1d1 can be rotated so that the limit rod 1d2 contacts the workpiece without affecting the movement of the workpiece, thereby limiting the movement trajectory of the workpiece in the detection terminal 1, improving the stability of the workpiece moving process in the detection terminal 1, thereby reducing the fluctuation of the workpiece when passing through the detection equipment without affecting the quality of the workpiece, thereby ensuring the accuracy of the detection result, and further ensuring the accuracy of the detection equipment in judging the quality of the electroplated workpiece.

[0038] refer to Figure 4 As shown, in order to solve the problem of up and down fluctuation of the workpiece, the limiting mechanism 1d also includes a chuck frame 1d3, a lower chuck wheel 1d4 and an upper chuck wheel 1d5. The two chuck frames 1d3 are symmetrically arranged along the moving trajectory of the workpiece in the detection terminal 1 with the detection position 1b as the center. The lower chuck wheel 1d4 is rotatably arranged on the chuck frame 1d3 and is located below the workpiece. The upper chuck wheel 1d5 is rotatably arranged on the chuck frame 1d3 and is located above the workpiece. The sides of the lower chuck wheel 1d4 and the upper chuck wheel 1d5 are provided with grooves. The workpiece passes through the gap between the lower chuck wheel 1d4 and the upper chuck wheel 1d5 through the grooves. The grooves contact the workpiece, thereby further limiting the moving trajectory of the workpiece in the detection terminal 1, improving the stability of the workpiece in the moving process in the detection terminal 1, thereby reducing the fluctuation of the workpiece when passing through the detection equipment without affecting the quality of the workpiece, thereby ensuring the accuracy of the detection result, and further ensuring that the detection equipment can accurately judge the quality of the electroplated workpiece.

[0039] When inspecting different workpieces, in order to make the lower clamping wheel 1d4 and the upper clamping wheel 1d5 contact with the workpiece without affecting the movement of the workpiece, it is necessary to adjust the interval between the lower clamping wheel 1d4 and the upper clamping wheel 1d5.

[0040] refer to Figure 4As shown, a slide groove is provided on the wheel frame 1d3, and the lower wheel 1d4 and the upper wheel 1d5 are slidably arranged in the slide groove. The positions of the lower wheel 1d4 and the upper wheel 1d5 in the slide groove can be adjusted according to the width of different workpieces, thereby adjusting the interval between the lower wheel 1d4 and the upper wheel 1d5. Further, the limiting mechanism 1d also includes a first adjustment rod 1d6, which is arranged in the slide groove. The first adjustment rod 1d6 is used to adjust the positions of the lower wheel 1d4 and the upper wheel 1d5 in the slide groove, so that the lower wheel 1d4 and the upper wheel 1d5 contact with the workpiece without affecting the movement of the workpiece, thereby limiting the moving track of the workpiece in the detection terminal 1, improving the stability of the workpiece moving process in the detection terminal 1, thereby reducing the fluctuation of the workpiece when passing through the detection equipment without affecting the quality of the workpiece, thereby ensuring the accuracy of the detection result, and then ensuring the accuracy of the detection equipment in judging the quality of the electroplated workpiece.

[0041] The moving direction of the workpiece before entering the detection terminal 1 is somewhat different from the moving direction of the workpiece after entering the detection terminal 1. Therefore, in order to make the moving direction of the workpiece before and after entering the detection terminal 1 the same, a guide rod 1d7 and a guide seat 1d8 are provided at the feeding position 1a. The guide seat 1d8 is arranged along the moving trajectory of the workpiece in the detection terminal 1. The two guide rods 1d7 are symmetrically arranged on the guide seat 1d8. The workpiece passes through the gap between the two guide rods 1d7 and enters the detection terminal 1. The guide rod 1d7 contacts the workpiece, thereby changing the moving direction of the workpiece, and then making the moving direction of the workpiece the same before and after entering the detection terminal 1.

[0042] When the moving trajectory of the workpiece after leaving the detection terminal 1 is somewhat different from the moving trajectory of the workpiece in the detection terminal 1, in order to prevent the workpiece from affecting its movement in the detection terminal 1 after leaving the detection terminal 1, a first pressing wheel 1d9 and a second pressing wheel 1d10 are provided at the discharge position 1c. The first pressing wheel 1d9 and the second pressing wheel 1d10 are arranged on both sides of the moving trajectory of the workpiece in the detection terminal 1. When the workpiece passes through the interval between the first pressing wheel 1d9 and the second pressing wheel 1d10, the first pressing wheel 1d9 and the second pressing wheel 1d10 contact and squeeze the workpiece, thereby further restricting the movement of the workpiece in the detection terminal 1 and preventing the moving trajectory of the workpiece after leaving the detection terminal 1 from affecting the moving trajectory of the workpiece in the detection terminal 1.

[0043] When there is a special structure on the surface of the workpiece, in order to prevent it from being crushed by the first pressing wheel 1d9 and the second pressing wheel 1d10, an avoidance groove is provided on the side of the pressing wheel. When the pressing wheel squeezes the workpiece, its special structure passes through the avoidance groove to avoid being crushed.

[0044] refer to Figure 5As shown, when inspecting different workpieces, the thickness of different workpieces is also different. In order to make the first pressing wheel 1d9 and the second pressing wheel 1d10 contact with the workpiece without affecting the movement of the workpiece, it is necessary to adjust the interval between the first pressing wheel 1d9 and the second pressing wheel 1d10. A fixed wheel frame and a movable wheel frame are provided at the discharge position 1c. The fixed wheel frame is arranged opposite to the first pressing wheel 1d9. The movable wheel frame can be movably arranged in the fixed wheel frame. The second pressing wheel 1d10 is fixedly arranged in the movable wheel frame. By adjusting the position of the movable wheel frame in the fixed wheel frame, the interval between the first pressing wheel 1d9 and the second pressing wheel 1d10 is adjusted. Furthermore, in order to better adjust the position of the movable wheel frame in the fixed wheel frame, a second adjustment rod is provided between the fixed wheel frame and the movable wheel frame.

[0045] refer to Figure 1 As shown, in order to prevent the external environment from affecting the detection of the workpiece by the detection terminal 1, the detection equipment also includes a light shielding hood 3, which is arranged on the outside of the detection terminal 1, and an opening is provided on the side of the light shielding hood 3 near the feed position 1a and the discharge position 1c to facilitate the entry and exit of the workpiece, and an openable and closable cover door is provided on the side of the light shielding hood 3 facing the detection position 1b to facilitate the staff to adjust the detection terminal 1.

[0046] Specifically, the detection equipment also includes a frame 4, the detection terminal 1 and the display terminal 2 are arranged on the frame 4, and the control terminal is arranged in the frame 4. Due to the complex factory environment, when the detection equipment is placed in an uneven place, in order to avoid the detection of the workpiece by the detection terminal 1, the detection equipment also includes a leveling rod 5, and the leveling rod 5 is arranged between the detection terminal 1 and the frame 4. The leveling rod 5 can keep the detection terminal 1 in a horizontal state.
