[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Figure 1 , Figure 2 and Figure 3 The visual inspection device shown is applied to standard hardware parts, including a bottom adjustment base 1, an upper adjustment base 2 movably mounted on the upper end of the bottom adjustment base 1, a detachable transparent support plate 3 fixedly mounted on the upper end of the upper adjustment base 2, a top side guide cover 4 fixedly mounted on the outer side of the bottom adjustment base 1 by a lateral bracket, an electrically controlled adjustment cover 5 movably mounted on the outer side of the bottom adjustment base 1, a top lifting plate 6 mounted on the outer side of the electrically controlled adjustment cover 5 by an external control bracket, a flip-type inspection arm 7 movably mounted on the lower end of the top lifting plate 6, and an optical visual inspection probe 8 mounted on the inner wall of the flip-type inspection arm 7.

[0024] To facilitate active control, a main control motor 9 is installed inside the bottom adjustment seat 1, and a bottom mounting shaft 21 with a downward protrusion is located at the lower end of the upper adjustment seat 2. Both the outer side of the bottom mounting shaft 21 and the control shaft at the lower end of the main control motor 9 are equipped with meshing main control gears 22.

[0025] The main control motor 9 drives the bottom assembly shaft 21 to rotate, thereby adjusting the upper adjustment seat 2 and the detachable transparent support plate 3 to rotate, thereby driving the hardware on the detachable transparent support plate 3 to rotate circumferentially, guiding the hardware onto the detachable transparent support plate 3 from one end, and then exporting the hardware from the other end.

[0026] To accommodate height adjustment and fit different hardware specifications, a strip-shaped opening is provided inside the side bracket, and the top guide cover 4 is fixedly installed on the side bracket through the mounting bolts inside the strip-shaped opening.

[0027] To facilitate the external adjustment control, an annular mounting groove for installing the electric adjustment cover 5 is provided on the outer side of the bottom adjustment seat 1. The electric adjustment cover 5 includes an external adjustment cover 51 fitted on the annular mounting groove, an inner adjustment motor 52 installed inside the annular mounting groove, and an inner adjustment gear 53 controlled by the inner adjustment motor 52.

[0028] The inner adjusting motor 52 drives the outer adjusting cover 51 to rotate along the annular assembly groove through the inner adjusting gear 53.

[0029] To accommodate the bottom movable assembly, the lower end of the top lifting plate 6 has a downwardly protruding bottom assembly shaft cylinder 61.

[0030] To accommodate the top rotation adjustment, the flip-type detection arm 7 includes a bottom rotating cover 71 movably mounted on the bottom mounting cylinder 61, a top adjustment motor 72 mounted on the top lifting plate 6, and longitudinal adjustment arms 73 fixed on both sides of the lower end of the bottom rotating cover 71.

[0031] The top adjustment motor 72 drives the bottom rotating cover 71 to rotate along the bottom mounting shaft tube 61, thereby controlling the vertical adjustment arms 73 on both sides of the lower end to rotate around the hardware parts.

[0032] To facilitate lateral assembly, an arc-shaped assembly cover 74 is fixedly installed on the lower inner side of the longitudinally placed adjusting arm 73.

[0033] To facilitate lateral visual inspection and provide supplementary lighting, the optical visual inspection probe 8 is fixedly installed in the middle of the inner side of the arc-shaped assembly cover 74. LED flat panel lights 10 that cooperate with the optical visual inspection probe 8 are installed on both sides of the inner side of the arc-shaped assembly cover 74.

[0034] By providing supplemental lighting from both sides, the impact of shadows on the surface of hardware parts on visual inspection can be greatly reduced.

[0035] To facilitate optical positioning of the lower hardware components, an optical positioning probe 11 is fixedly mounted on the lower end of the bottom mounting cylinder 61.

[0036] The optical positioning probe 11 performs downward optical scanning and uses visual inspection technology for positioning, thereby controlling the top hanging plate 6 to move with the hardware on the upper surface of the detachable transparent support plate 3, ensuring the relative position during the inspection process.

[0037] To facilitate high-pressure air separation and to easily blow away unqualified products from the sieve, the lower surface of the bottom adjusting seat 1 is provided with a bottom opening. The bottom limiting seat 11 is fixed to the lower end of the bottom opening with bolts. The upper end of the bottom limiting seat 11 is fixedly equipped with a top air guide pipe 12 that is connected to the external air supply pipe. A side electrically controlled air valve 13 is axially mounted on the top air guide pipe 12 above the detachable transparent support plate 3.

[0038] When the optical vision inspection probe 8 detects a faulty hardware component, the side electric control air valve 13 is activated, controlling the high-pressure air introduced by the external air supply pipe to enter along the top air guide pipe 12, and then sprayed out by the side exhaust nozzle of the side electric air valve 13.

[0039] Equipment working principle The equipment is designed around the core logic of "precise follow-up detection + automated conveying and separation". The various systems work together to achieve efficient detection of standardized hardware parts. The specific principle is broken down as follows: Power transmission and conveying principle: The equipment uses the main control motor 9 as the core power source. After the main control motor 9 starts, its lower control shaft drives the main control gear 22 on the surface to rotate. Because the main control gear 22 meshes with the gear on the outer side of the bottom mounting shaft 21, the power is transmitted to the bottom mounting shaft 21 through gear transmission, which in turn drives the upper adjusting seat 2, which is fixedly connected to the bottom mounting shaft 21, to rotate synchronously. The detachable transparent support plate 3 at the upper end of the upper adjusting seat 2 moves in a uniform circular motion with the upper adjusting seat 2, forming a continuous "introduction-detection-export" conveying path, ensuring that the hardware parts (such as screws and nuts) maintain a stable movement rhythm during the detection process, and avoiding the impact of conveying interruption on detection efficiency.

[0040] Positioning and Follow-up Adjustment Principle: The optical positioning probe 11 at the lower end of the bottom mounting shaft 61 scans the hardware on the detachable transparent support plate 3 in real time. It captures the center coordinates, movement speed, and posture (such as whether the screws are tilted) of the hardware through visual recognition technology and transmits the positioning signal to the equipment control system. The control system regulates two key adjustment structures according to the signal: one is the inner adjustment motor 52 of the electric control adjustment cover 5, which drives the inner adjustment gear 53 to rotate. Because the inner adjustment gear 53 meshes with the tooth groove on the inner side of the outer adjustment cover 51, it drives the outer adjustment cover 51 to rotate along the annular mounting groove on the outer side of the bottom adjustment seat 1, thereby realizing the circumferential position adjustment of the top hanging plate 6; the other is the top adjustment motor 72 of the flip-type detection arm 7, which drives the bottom rotating cover 71 to rotate along the bottom mounting shaft 61, thereby causing the longitudinal adjustment arm 73 at the lower end of the bottom rotating cover 71 to rotate synchronously. The two adjustment actions work together to ensure that the optical vision inspection probe 8 in the arc-shaped assembly cover 74 inside the vertical adjustment arm 73 always remains relatively stationary with respect to the hardware, thus solving the problem of "image blurring due to movement" in traditional vision inspection and improving inspection accuracy.

[0041] Lighting and visual inspection principle: The LED flat panel lights 10 on both sides of the inner side of the arc-shaped assembly cover 74 and the optical visual inspection probe 8 form a "symmetrical supplementary lighting-centered inspection" structure. The brightness of the LED flat panel lights 10 can be adjusted according to the material of the hardware (such as stainless steel, carbon steel) (range 100-500 lux), avoiding blind spots caused by reflections or shadows on the metal surface. The optical visual inspection probe 8 uses a high-resolution industrial camera (pixels ≥ 2 million) to perform 360° surround image acquisition of the hardware during the tracking process. The acquisition frequency is matched with the movement speed of the hardware (such as 15-25 frames per second). The images are transmitted to the background algorithm system in real time. By comparing the dimensional parameters (such as diameter, length, thread pitch), surface defects (such as scratches, burrs, cracks), and shape integrity of the standard hardware, the system can quickly determine whether the product is qualified.

[0042] Defective Product Separation Principle: When the background algorithm determines that a certain hardware part is defective, it immediately sends a trigger signal to the side-controlled air valve 13 below the bottom adjustment seat 1. After receiving the signal, the side-controlled air valve 13 opens instantly (response time ≤ 0.3 seconds). High-pressure gas (pressure 0.5-0.8MPa) delivered by the external air supply pipe enters the side-controlled air valve 13 through the top air guide pipe 12, and then is directionally ejected from the side exhaust nozzle of the side-controlled air valve 13. The airflow precisely acts on the defective hardware part on the detachable transparent support plate 3, blowing it away from the conveying path and causing it to fall into the preset defective product collection box; qualified hardware parts are unaffected and continue to move with the detachable transparent support plate 3 to the outlet end.

[0043] Structural Adaptation and Maintenance Principle: The equipment adopts a multi-set detachable structural design. For example, the detachable transparent support plate 3 is fixed to the upper adjustment seat 2 by bolts. Support plates with different hole diameters or bearing areas can be replaced according to the size of the hardware (such as M3-M12 screws). The top side guide cover 4 is fixed by the strip opening of the side bracket and the mounting bolts. The height can be adjusted up and down by loosening the bolts (adjustment range 50-150mm) to accommodate the introduction of hardware of different heights. The bottom limit seat 14 is connected to the bottom opening of the bottom adjustment seat 1 by bolts. After disassembly, the top air guide pipe 12 or the side electric control air valve 13 can be inspected and repaired, reducing the difficulty and cost of later maintenance.

[0044] Equipment working process The equipment operation process involves seven core stages: pre-processing, conveyor start-up, positioning and follow-up, lighting detection, separation of defective products, export of qualified products, and shutdown maintenance. The specific operations and component coordination of each stage are as follows: Phase 1: Pre-processing (Preparation before testing) According to the specifications of the standard hardware to be tested (such as the outer diameter of the nut and the length of the bolt), adjust the height of the top side guide cover 4: loosen the mounting bolts in the strip opening of the side bracket, move the top side guide cover 4 up and down to the appropriate position (ensure that the hardware can pass through smoothly without jamming), and then tighten the mounting bolts to fix it.

[0045] Replace the detachable transparent support plate 3: If the hole diameter or surface anti-slip structure of the existing support plate does not match the current hardware, unscrew the bolts connecting the support plate and the upper adjustment seat 2, replace with a suitable support plate and then fix it again.

[0046] Check the air and electrical circuits: confirm that the top air duct 12 is sealed to the external air supply pipe and that the side electric air valve 13 is closed; check that the power cords of the main control motor 9, the inner adjustment motor 52, and the top adjustment motor 72 are connected normally, that the lenses of the optical vision detection probe 8 and the optical positioning probe 11 are not covered by dust, and that the LED flat panel light 10 can be lit normally.

[0047] Set the detection parameters: Input the standard parameters of the hardware to be inspected (such as dimensional tolerance ±0.05mm, surface defect judgment threshold) through the equipment control system, and calibrate the image acquisition range and comparison benchmark of the optical vision inspection probe 8.

[0048] Phase 2: Start Conveying (Hardware Component Import and Movement) Start the main control motor 9. The main control motor 9 drives the main control gear 22 on the lower control shaft to rotate. The main control gear 22 meshes with the gear on the outer side of the bottom mounting shaft 21, driving the bottom mounting shaft 21 and the upper adjustment seat 2 to rotate at a preset speed (5-10 r / min). The detachable transparent support plate 3 at the upper end of the upper adjustment seat 2 rotates synchronously.

[0049] The standard hardware parts (such as screws) to be tested are poured in batches into the feed port of the top side guide cover 4. The inclined structure of the top side guide cover 4 guides the hardware parts to be evenly dispersed and fall one by one into the preset bearing position (such as the groove or positioning hole on the surface of the support plate) of the detachable transparent support plate 3, so as to avoid the hardware parts from stacking or deviating from the conveying path.

[0050] Phase 3: Positioning and Follow-up Adjustment (Ensure the detection probe and hardware are relatively stationary) The optical positioning probe 11 at the lower end of the bottom mounting shaft cylinder 61 is activated, scanning the hardware on the detachable transparent support plate 3 downwards at a frequency of 10-15 times per second, collecting the position coordinates (X / Y axis), movement speed and attitude data of the hardware in real time, and transmitting the data to the control system.

[0051] The control system analyzes the positioning data. If it detects a positional shift or speed change of a certain hardware component, it immediately sends a command to the inner adjustment motor 52 of the electric adjustment cover 5. The inner adjustment motor 52 drives the inner adjustment gear 53 to rotate, which in turn drives the outer adjustment cover 51 to rotate along the annular assembly groove of the bottom adjustment seat 1. This causes the top lifting plate 6 on the outer adjustment cover 51 to move synchronously and adjust the circumferential position of the flip-type detection arm 7.

[0052] At the same time, the control system sends a command to the top adjustment motor 72 of the flip-type detection arm 7: the top adjustment motor 72 drives the bottom rotating cover 71 to rotate along the bottom mounting cylinder 61, and the vertical adjustment arm 73 at the lower end of the bottom rotating cover 71 rotates with it, so that the arc-shaped mounting cover 74 inside the vertical adjustment arm 73 is aligned with the hardware.

[0053] The above adjustment process continues until the relative positional error between the optical vision inspection probe 8 and the hardware is ≤0.1mm, ensuring that the probe can stably acquire clear images of the hardware during subsequent inspections.

[0054] Phase 4: Illumination and Surround Inspection (Image Acquisition and Acceptance Determination) When the optical vision inspection probe 8 and the hardware part reach a relatively stationary state, the control system triggers the LED flat panel light 10 inside the arc-shaped assembly cover 74 to turn on, and adjusts the brightness according to the material of the hardware part (e.g., when inspecting stainless steel screws, the brightness is adjusted to 400 lux to avoid reflection; when inspecting carbon steel nuts, it is adjusted to 300 lux to enhance contrast) to ensure that there are no obvious shadows on the surface of the hardware part.

[0055] The optical vision inspection probe 8 starts image acquisition and performs 360° surround shooting of the hardware part at a frequency of 20-25 frames per second: the vertical adjustment arm 73 slowly rotates with the bottom rotating cover 71 (rotation speed 1-2r / min), driving the optical vision inspection probe 8 to acquire images from multiple angles such as the top, side and bottom of the hardware part, covering the entire surface of the hardware part (including key parts such as threads, end faces and chamfers).

[0056] The acquired images are transmitted to the backend algorithm system in real time, and the system compares the images with preset standard hardware parameters: Dimensional comparison: Check whether the outer diameter, length, thread pitch, and other dimensions of the hardware parts are within the tolerance range; Surface defect comparison: Identify the presence of defects such as scratches (depth > 0.02 mm), burrs (height > 0.03 mm), cracks, and missing corners; External integrity comparison: Check whether the hardware parts are deformed, have missing threads, or have hole diameter deviations.

[0057] The algorithm system completes the single-item judgment within 0.5 seconds, generates a "qualified" or "unqualified" result, and synchronizes the result to the equipment control system.

[0058] Phase 5: Separation of Non-conforming Products (Precise Removal of Non-conforming Products) If the judgment result is "unqualified", the control system records the position of the hardware on the detachable transparent support plate 3 and calculates the time it takes to reach the side electric control valve 13 (calculated based on the rotation speed and distance of the support plate).

[0059] When the defective hardware moves to the side electric control valve 13, the control system sends an "open" signal to the side electric control valve 13. The side electric control valve 13 opens instantly, and the high-pressure gas from the external air supply pipe enters the valve through the top air guide pipe 12 and is then sprayed out directionally from the side exhaust nozzle. The airflow precisely acts on the side or bottom of the defective hardware, blowing it away from the bearing position of the detachable transparent support plate 3 and causing it to fall into the defective product collection box below.

[0060] After separation is completed, the lateral electronically controlled air valve 13 immediately closes, waiting for the next defective product trigger signal to avoid continuous air jetting that would waste energy or interfere with qualified hardware.

[0061] Phase 6: Export of qualified products (completion of testing and collection) The hardware parts that are deemed "qualified" continue to move in a circular motion along with the detachable transparent support plate 3. When they move to the outlet end of the equipment (the side opposite to the top guide cover 4), due to the rotational inertia of the support plate and the tilting guide structure of the outlet end, the qualified hardware parts automatically slide off the support plate and enter the preset qualified product storage box.

[0062] If the hardware parts are too light or have a smooth surface to slide off automatically, a small conveyor belt or air blowing auxiliary device (sharing the air circuit with the side electric control air valve 13) can be added to the outlet end to ensure that qualified hardware parts are smoothly discharged and avoid accumulating on the support plate.

[0063] Phase 7: Shutdown Maintenance (Post-Inspection Cleanup) After all the hardware parts to be inspected have been transported and inspected, the main control motor 9 is turned off, the detachable transparent support plate 3 gradually stops rotating, and then the power supply to components such as the LED flat panel light 10, the optical vision inspection probe 8, and the optical positioning probe 11 is turned off.

[0064] Remove the detachable transparent support plate 3, use compressed air to blow away dust and debris from the surface of the support plate, and if there is oil, wipe it with a neutral detergent and let it dry before reinstalling it back into the upper adjustment seat 2.

[0065] Check the lenses of the optical vision inspection probe 8 and the optical positioning probe 11. Gently wipe the surface dirt with lens paper to ensure clear images for the next inspection. Check the top air duct 12 for blockage. If there is a blockage, remove it and blow it out with high-pressure air. Check the operating noise of each motor (main control motor 9, inner adjustment motor 52, top adjustment motor 72). If the noise is abnormal, check whether the bearings or gears are worn.

[0066] Clean the non-conforming product collection box and the conforming product storage box, count the number of tests, the number of conforming products, and the number of non-conforming products, generate a test report, and complete the entire workflow.

[0067] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
