Description

Technical Field

[0001] This invention belongs to the field of automatic testing equipment technology, specifically relating to a detection angle adjustment device for automatic testing equipment and a transparent glass turntable used in conjunction with it. Background Technology

[0002] In the production of rubber rings, hidden cracks are a significant defect affecting product quality and require precise identification using fully automated testing equipment. The detection angle adjustment device, as a core component of fully automated rubber ring hidden crack detection equipment, directly determines the detection coverage and efficiency. Existing mainstream detection solutions suffer from the following serious shortcomings:

[0003] Firstly, its functionality is limited and it relies on auxiliary equipment. Existing image capture units are typically fixed in structure with non-adjustable angles, meaning a single shot can only capture a single perspective of the rubber ring (e.g., the top surface). To complete full-surface inspection of the product, it must work in conjunction with a flipping machine: first, one side is photographed, then the flipping machine rotates the product 180° to photograph the other side. This approach not only increases equipment complexity and floor space but also severely reduces inspection efficiency, becoming a bottleneck in the production line.

[0004] Secondly, it lacks dynamic detection capabilities. The fixed capture unit cannot continuously and multi-anglely scan and capture images of the side circumference of the rubber ring, making it easy to miss annular cracks or defects hidden in the sidewall. At the same time, the mechanical movement of the flipping machine has positioning errors and vibrations, affecting image clarity and detection accuracy.

[0005] Third, the cost is high and maintenance is complex. As a high-precision motion mechanism, the tilting machine itself has problems such as high purchase cost, many failure points, and complex maintenance, which increases the overall life cycle cost of the equipment.

[0006] Therefore, there is an urgent need for a new type of angle adjustment device that can replace the flipping machine and achieve omnidirectional inspection at a single station. This invention aims to enable a single image capture unit to independently complete 360° omnidirectional imaging of the upper, lower, and side surfaces of a rubber ring by working in conjunction with a transparent glass turntable. This completely eliminates the dependence on the flipping machine, thereby increasing inspection coverage while doubling efficiency and reducing costs. Summary of the Invention

[0007] The purpose of this invention is to provide a detection angle adjustment device for automatic detection equipment to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a detection angle adjustment device for an automatic detection equipment, comprising a mounting base, a linear drive assembly, a rotary drive assembly, a capture assembly, and a light source assembly;

[0009] The linear drive component is fixedly mounted on the mounting base, the rotary drive component is connected to the linear drive component through a connecting structure, the snapshot component is mounted on the output end of the linear drive component, and the light source component is set to correspond to the shooting area of ​​the snapshot component.

[0010] Preferably, the linear drive assembly includes a servo linear motor, a lead screw and slider, and a module base; the servo linear motor is fixedly mounted on the module base, the module base is connected to the rotary drive assembly, and the capture assembly is mounted on the lead screw and slider of the linear drive assembly. By driving the lead screw and slider to move precisely through the servo linear motor, the capture assembly can be stably adjusted in the vertical direction, avoiding the impact of positional deviation on imaging quality.

[0011] Preferably, the rotary drive assembly includes a servo rotary motor, a gear rotary module, and a rotary connecting plate; the output shaft of the servo rotary motor is connected to the rotary connecting plate via the gear rotary module, the module seat of the linear drive assembly is fixed on the rotary connecting plate, and the servo rotary motor drives the rotary connecting plate to rotate precisely via the gear rotary module, thereby causing the linear drive assembly and the capture assembly to rotate synchronously, which can flexibly adjust the capture angle and realize side shooting of the rubber ring, filling the gap that traditional fixed capture units cannot detect the side, and avoiding missed detection of hidden cracks in the side wall.

[0012] Preferably, the linear drive assembly further includes photoelectric limit switches, which are installed at both ends of the module base to limit the travel of the lead screw and slider. This effectively prevents the slider from overtraveling, which could lead to overload of the servo linear motor or mechanical collision damage to the lead screw or slider, ensuring safe operation of the device and reducing the risk of equipment failure. It also prevents the capture assembly from deviating from the reasonable shooting range due to excessive slider movement, ensuring that each adjustment is within the effective detection range, thus improving the stability and reliability of the device operation.

[0013] Preferably, the rotary drive assembly is slidably mounted on the mounting base via a slider, which can quickly adapt to the testing requirements of different product models according to the diameter, thickness and other size specifications of the rubber ring, without the need to replace the entire device, thus improving the equipment's versatility.

[0014] Preferably, the capture component includes a camera and a lens, the light source component is mounted on the module base via an L-shaped bracket, the light source component is located at the front end of the lens, and the illumination direction of the light source component is towards the shooting area of ​​the capture component.

[0015] Preferably, it also includes a dust cover, which covers the outside of the linear drive assembly and the rotary drive assembly, and can effectively isolate dust, oil and other impurities in the production environment.

[0016] Preferably, the linear drive component further includes a drive interface, which is electrically connected to the servo linear motor and used to receive external control signals. This enables automated control of the linear drive component without manual adjustment, adapting to the automated operation requirements of the production line and improving testing efficiency.

[0017] A transparent glass turntable includes a transparent glass disk, a belt drive wheel, a magnetic coupling, a servo motor, and a belt;

[0018] The transparent glass disk and the belt drive wheel are both horizontally mounted on the support plate via bearings and are connected by belt drive. The output shaft of the servo motor is connected to the belt drive wheel via a magnetic coupling to drive the transparent glass disk to rotate around its own central axis. The object placement area of ​​the transparent glass disk corresponds to the shooting area of ​​the capture component, and is used to place the rubber ring to be tested.

[0019] Preferably, a supplementary light source is provided on the outside of the support plate via a bracket.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. Achieve all-around inspection and eliminate blind spots: With the help of the vertical movement of the linear drive component and the angular flipping of the rotary drive component, combined with the transparent glass turntable, a single device can complete the imaging of the upper end, lower end and side of the rubber ring, covering the entire surface for inspection and avoiding missed detection of hidden cracks.

[0022] 2. Improve inspection efficiency: Eliminate the "shoot-flip-second shooting" process, shorten the inspection cycle of a single rubber ring, reduce equipment linkage failures, and improve the stability of continuous production line operation.

[0023] 3. Reduced costs and maintenance difficulty: Eliminating the purchase cost of the tilting machine reduces equipment procurement costs; the device has a simplified structure and fewer potential failure points, and the dust cover reduces component wear, extends maintenance cycles, and reduces operation and maintenance costs.

[0024] 4. Improve detection accuracy and ensure accurate identification: Avoid rubber ring position shift caused by flipping, and combine with stable illumination from the front-end light source to improve imaging clarity and image contrast, thereby increasing the accuracy of hidden crack identification and reducing the false judgment rate.

[0025] 5. The rotary drive assembly can be slidably adjusted to adapt to the detection of rubber rings of different sizes; the drive interface is easy to connect to the main control system, the modular design facilitates subsequent upgrades, adapts to changes in production lines and testing standards, photoelectric limit switches prevent overtravel failures of the lead screw and slider, and dust covers isolate impurities, reduce component wear, ensure safe operation of the device, and extend the overall service life.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 - Figure 4 This invention illustrates a specific embodiment of a detection angle adjustment device for an automatic detection equipment: it includes a mounting base 1, a linear drive assembly 2, a rotary drive assembly 3, a capture assembly 4, a light source assembly 5, and a dust cover 6. The specific connections and operation of each component are as follows:

[0033] Basic installation structure:

[0034] Mounting base 1 is made of high-strength aluminum alloy plate with rust-proof surface treatment. It serves as the support carrier for the entire device. The rotary drive component 3 slides and engages with the slide rail on the surface of mounting base 1 through the bottom slider 11. The position can be adjusted laterally along the slide rail to adapt to the detection requirements of rubber rings of different sizes.

[0035] Linear drive component 2:

[0036] Linear drive assembly 2 includes a servo linear motor 21, a lead screw slider 22, a module base 23, a photoelectric limit switch 24, and a drive interface 25. The module base 23 is bolted to the rotary connecting plate 33 of the rotary drive assembly 3. The servo linear motor 21 is horizontally mounted on one side of the module base 23, and its output lead screw is threadedly connected to the lead screw slider 22, which can slide vertically along the guide rail of the module base 23. The photoelectric limit switch 24 is fixed to the upper and lower ends of the module base 23 via brackets and is electrically connected to the controller of the servo linear motor 21. The drive interface 25 is welded to the side of the module base 23, with one end electrically connected to the servo linear motor 21 and the other end connectable to the main control system of the automatic detection equipment.

[0037] Rotary drive component 3:

[0038] The rotary drive assembly 3 consists of a servo rotary motor 31, a gear rotary module 32, and a rotary connecting plate 33. The servo rotary motor 31 is fixed to the housing of the rotary drive assembly 3 via a motor bracket, and its output shaft is connected to the driving gear of the gear rotary module 32 via a coupling. The driven gear of the gear rotary module 32 is welded and fixed to the center of the rotary connecting plate 33, which can drive the rotary connecting plate 33 to rotate within a range of ±90° around the horizontal axis. The side of the rotary connecting plate 33 away from the gear module is bolted to the module seat 23 of the linear drive assembly 2, realizing the linkage between the linear drive assembly and the rotary drive assembly.

[0039] Capture and Light Source Components:

[0040] The image capture assembly 4 includes an industrial camera 41 and a high-definition lens 42. The camera 41 is bolted to the side of the lead screw slider 22 via an L-shaped mounting bracket. The lens 42 is threaded to the shooting end of the camera 41, and the central axis of the lens is aligned with the product placement area of ​​the transparent glass turntable. The light source assembly 5 uses a ring-shaped LED light source, which is fixed to the module base 23 near the lens 42 via an L-shaped bracket 51. The center of the light source is coaxial with the center of the lens 42, and the illumination direction is perpendicular to the transparent glass turntable, providing uniform illumination to the shooting area.

[0041] Dustproof protective structure:

[0042] Dustproof cover: 6 is made of transparent acrylic material and is connected to the housing of mounting base 1 and rotary drive component 3 by buckle. It covers the non-shooting area of ​​linear drive component 2, rotary drive component 3 and snapshot component 4, isolating dust, oil and other impurities, while not affecting the shooting field of view and component adjustment.

[0043] The detection angle adjustment device of this automatic detection equipment needs to be used in conjunction with a transparent glass turntable; the transparent glass turntable includes a transparent glass disk 8, a belt drive wheel 9, a magnetic coupling 10, a servo motor 12, and a belt 13;

[0044] The transparent glass disk 8 and the belt drive wheel 9 are both horizontally mounted on the support plate 14 via bearings and are connected by a belt 13. The output shaft of the servo motor 12 is connected to the belt drive wheel 9 via a magnetic coupling 10 to drive the transparent glass disk 8 to rotate around its own central axis. The placement area of ​​the transparent glass disk 8 corresponds to the shooting area of ​​the capture component 4, and is used to place the rubber ring to be tested. A supplementary light source 15 is provided on the outside of the support plate 14 via a bracket. The brightness is independently adjustable and is used to supplement the shooting light on the side of the rubber ring and eliminate shadows.

[0045] Operating procedure of this device:

[0046] This device requires the use of a transparent glass turntable. The rubber ring to be tested is placed on the transparent glass turntable 7 via a feeding mechanism.

[0047] Rubber ring upper end detection: The main control system sends a signal to the servo linear motor 21 through the drive interface 25, driving the lead screw slider 22 to move upward along the module base 23, and moving the capture component 4 to a position 15-20cm above the transparent glass turntable. The position is adjusted according to the thickness of the rubber ring. The photoelectric limit switch 24 monitors the slider position and feeds back to the system to ensure accurate positioning. Then the light source component 5 is turned on, and the industrial camera 41 captures the image of the upper end of the rubber ring through the lens 42. The image data is transmitted to the defect recognition system in real time.

[0048] Rubber ring bottom inspection: After the top end is captured, the servo linear motor 21 drives the lead screw slider 22 to move downward, moving the capture component 4 to a position 10-15cm below the transparent glass turntable. The light source component 5 continuously illuminates the transparent glass, and the industrial camera 41 captures the image of the bottom end of the rubber ring, completing the front and back inspection.

[0049] Rubber ring side inspection: After the lower end is captured, the servo rotary motor 31 starts and drives the rotary connecting plate 33 to rotate through the gear rotary module 32, so that the linear drive component 2 and the capture component 4 are simultaneously flipped to a horizontal state with the lens facing the side of the rubber ring; at the same time, the rotary drive component 3 finely adjusts its position along the slide rail of the mounting base 1 through the slider 11 to ensure that the distance between the lens 42 and the side of the rubber ring is adapted; finally, the light source component 5 adjusts the brightness, and the industrial camera 41 captures the image of the side of the rubber ring. If 360° inspection is required, the transparent glass turntable servo motor 12 drives the glass disk to rotate at a constant speed, and the camera continuously captures multiple images to cover the 360° side.

[0050] After the inspection is completed, all components are reset: the rotary drive component flips back to the vertical position, the lead screw and slider return to their original positions, and the glass disk stops; based on the identification results, the feeding mechanism sends qualified rubber rings to the finished product box and unqualified products to the waste box, and the device enters the next inspection cycle.

[0051] The applicant further declares that while the above embodiments illustrate the implementation method and apparatus structure of the present invention, the present invention is not limited to the above-described embodiments, meaning that the present invention must rely on the above methods and structures to be implemented. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions for the selected implementation methods, additions to steps, and selections of specific methods all fall within the protection and disclosure scope of the present invention.
