Description

Technical Field

[0001] This utility model relates to the field of sample defect detection technology, and in particular to a sample defect detection device based on automated engineering. Background Technology

[0002] In the field of automated manufacturing, defect detection of samples (such as precision parts, electronic components, and optical lenses) is a crucial step in ensuring product quality. Current mainstream automated inspection equipment typically uses conveyor belts in conjunction with vision inspection systems to achieve rapid single-sided inspection. However, for samples requiring double-sided inspection, existing technologies have significant limitations: 1. In traditional testing processes, achieving double-sided sample testing typically requires two independent positioning operations. For example, the front of the sample is tested first, and then manually or with additional mechanical equipment, the sample needs to be flipped and repositioned at the testing station before the back side is tested. This process not only increases operational complexity and time costs, but more importantly, the secondary positioning easily introduces positioning errors, leading to shifts in the testing position, decreased repeatability, and severely impacting the reliability of the test results.

[0003] 2. Some automated inspection equipment achieves double-sided inspection by setting up multiple independent workstations or adding flipping mechanisms. However, such designs are often complex in structure and occupy a large area, making them difficult to integrate into compact production lines. For example, solutions using dual handling and transfer mechanisms or independent flipping modules require additional drive sources and control systems to work together, increasing equipment costs and maintenance difficulty, and making it difficult to meet the real-time inspection requirements of high-speed production lines. At the same time, the complex mechanical structure may also introduce vibration or motion instability factors, interfering with the accuracy of optical inspection. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the background art, this utility model provides a sample defect detection device for automated engineering.

[0005] The technical implementation scheme of this utility model is as follows: a sample defect detection device for automated engineering, comprising a base, a conveyor belt mechanism, a detection cavity, a support frame, an optical detection head, a lighting lamp, an electric slide rail, a slider, an electric push rod, a gear, a rack, a clamping arm, a floating clamp, and a buffer spring. The conveyor belt mechanism is mounted on the base, and the detection cavity is connected to the top right side of the base. Inlet and outlet ports are opened on both sides of the detection cavity. The support frame is connected to and extends through both sides of the detection cavity. An optical detection head is installed in the middle of the top of the detection cavity. Lighting lamps are installed on either side of the optical detection head at the top of the support frame. An electric slide rail is installed on the right side inside the detection cavity, and a slider is slidably connected to the electric slide rail. An electric push rod is rotatably connected to the slider. A clamping arm is connected to the end of the telescopic rod of the electric push rod, and a floating clamp is slidably connected to the clamping arm. Buffer springs are connected between the floating clamp and the clamping arm on both sides. A gear is connected to the outside of the electric push rod, and a rack is installed inside the support frame at a position corresponding to the gear. The conveyor belt mechanism, lighting lamp, electric slide rail, and electric push rod are all electrically connected to an external control system.

[0006] Furthermore, the contact surface of the floating clamping block is covered with a polyurethane buffer layer, and its clamping surface is processed with anti-slip texture with a texture depth of 0.3-0.5mm.

[0007] Furthermore, it also includes support blocks, anti-interference baffles, torsion springs, and control components. Support blocks are symmetrically fixedly connected to the inlet and outlet positions on both sides of the detection cavity. Anti-interference baffles are rotatably connected between the two support blocks on the corresponding sides. When the anti-interference baffles are in the closed state, they completely seal the inlet and outlet positions on both sides of the detection cavity. Torsion springs are connected between the front and rear sides of the anti-interference baffles and the corresponding support blocks. Control components are provided on the detection cavity.

[0008] Furthermore, the anti-interference baffle is made of lightweight aluminum alloy plate, and the edges of the anti-interference baffle are equipped with sealing rubber strips.

[0009] Furthermore, the control assembly includes a sliding frame and a reset spring. The sliding frame is slidably connected to the front and rear sides of the detection cavity near the support block. A reset spring is connected between the sliding frame and the detection cavity. The outer end of the sliding frame abuts against the anti-interference baffle on the corresponding side. The inner end of the sliding frame is machined with a guide slope and keeps in contact with the clamping arm.

[0010] Furthermore, the inner wall of the detection chamber is coated with a matte black light-absorbing coating, and an anti-static light-shielding film is attached to the inner side of the anti-interference baffle.

[0011] This utility model has the following advantages: 1. By utilizing the linkage design of electric slide rail driving lifting and gear-rack meshing, the vertical displacement and precise 180° flip of the sample can be realized simultaneously under the action of a single driving source (electric slide rail). The structure is compact and the movement is reliable, solving the problem of needing secondary positioning or additional flipping equipment for double-sided detection.

[0012] 2. Through the coordinated action of the conveyor belt mechanism, electric slide rail, electric push rod and control system, the sample transportation, precise positioning, flexible clamping, double-sided defect detection, posture reset and unloading cycle are completed automatically, which significantly improves the detection efficiency and reduces manual intervention.

[0013] 3. The clamping mechanism consisting of floating clamps and buffer springs can adaptively adjust the applied force after contacting the sample to avoid rigid impact damage to the sample. At the same time, it can automatically center the sample to ensure the consistency of the detection position and improve the detection accuracy and repeatability.

[0014] 4. The design of the anti-interference baffle and its linkage control components (sliding frame, return spring, torsion spring) automatically seals the inlet and outlet of the detection cavity during the detection phase through mechanical linkage with the movement of the clamping arm, effectively shielding external stray light interference; it automatically opens after detection to ensure smooth material flow. This design eliminates the need for an independent drive source, improving the stability and reliability of optical detection. Attached Figure Description

Detailed Implementation

[0020] Example: A sample defect detection device based on automated engineering, such as... Figures 1-2As shown, the device includes a base 1, a conveyor belt mechanism 2, a detection chamber 3, a support frame 4, an optical detection head 5, an illumination lamp 6, an electric slide rail 7, a slider 8, an electric push rod 9, a gear 10, a rack 11, a clamping arm 12, a floating clamp 13, and a buffer spring 14. The base 1 is equipped with a conveyor belt mechanism 2 for transporting samples. The detection chamber 3 is fixedly connected to the top right side of the base 1. The left and right side walls of the detection chamber 3 have inlets and outlets for sample passage. The inner wall of the detection chamber 3 is coated with a matte black light-absorbing coating (reflectivity ≤5%). The front and rear sides of the detection chamber 3 are fixedly connected to and penetrate the support frame 4. An optical detection head 5 for defect detection is bolted to the top center of the detection chamber 3. Illumination lamps 6 are bolted to the top of the support frame 4 at positions before and after the optical detection head 5 to provide stable and uniform detection illumination. A vertically arranged electric slide rail 7 is bolted to the right side of the inside of the detection chamber 3. A slider 8 is slidably connected to the electric slide rail 7. An electric push rod 9 is rotatably connected to the slider 8 via a bearing. A clamping arm 12 is connected to the telescopic end of the electric push rod 9. A floating clamping block 13 is slidably connected to the clamping arm 12. Buffer springs 14 are connected between the left and right sides of the floating clamping block 13 and the clamping arm 12, forming a floating clamping mechanism. The contact surface of the floating clamping block 13 is covered with a polyurethane buffer layer (thickness ≥ 2 mm). Its clamping surface is processed with anti-slip texture (texture depth 0.3-0.5 mm) to improve the stability when clamping the sample and avoid sample damage. A gear 10 is fixedly connected to the outside of the electric push rod 9. A rack 11 is bolted and installed inside the support frame 4 at the position corresponding to the gear 10. When the electric push rod 9 drives the gear 10 to move upward, the gear 10 will mesh with the rack 11 on the corresponding side. The conveyor belt mechanism 2, the lighting lamp 6, the electric slide rail 7, and the electric push rod 9 are all electrically connected to the external control system.

[0021] The working principle of sample defect detection is as follows: The transmission speed and positioning dwell time of the conveyor belt mechanism 2 are preset by the control system, and the optical detection head 5 and the illumination lamp 6 are started. The samples to be inspected are transported to the right sequentially by the conveyor belt mechanism 2. When the sample enters the detection area through the inlet and outlet of the detection cavity 3, the optical detection head 5 detects the sample signal. The control system then stops the operation of the conveyor belt mechanism 2 and starts the electric push rod 9. Its telescopic rod extends to drive the clamping arm 12 and the floating clamp 13 to move inward. After the floating clamp 13 contacts the sample, it achieves flexible clamping and automatic centering of the sample under the elastic action of the buffer spring 14. After the sample is fixed, the optical detection head 5 performs high-precision defect scanning detection on the top surface of the sample and records the data. After the front detection is completed, the electric slide rail 7 is started to drive the slider 8 to drive the electric push rod. 9. Gear 10, clamping arm 12, floating clamp 13, and the clamped sample move upward together. During the upward movement, gear 10 meshes with fixed rack 11. Under the constraint of rack 11, gear 10 drives electric push rod 9 and sample to rotate 180° around the axis and then stops. Optical inspection head 5 then performs defect detection on the back of the sample and records the data. After the back inspection is completed, electric slide rail 7 drives the assembly to move downward. During the downward movement, gear 10 and rack 11 mesh again to drive the sample to rotate 180° in the opposite direction to reset to the initial posture. After the sample falls back to conveyor belt mechanism 2, electric push rod 9 shortens and resets, driving clamping arm 12 and floating clamp 13 to move outward to release clamping. Buffer spring 14 resets and releases pre-pressure. Then conveyor belt mechanism 2 restarts, outputting the inspected sample to the station and sending the next sample to be inspected into the station, repeating the above inspection cycle.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes support blocks 17, anti-interference baffles 18, torsion springs 19, and control components. Support blocks 17 are symmetrically fixed to the left and right inlet and outlet positions of the detection cavity 3. Anti-interference baffles 18 are rotatably connected between the two support blocks 17 on the corresponding sides through a rotating shaft. When the anti-interference baffles 18 are in the closed state, they can completely seal the inlet and outlet on both sides of the detection cavity 3. The anti-interference baffles 18 are made of lightweight aluminum alloy plates, and their edges are provided with sealing rubber strips to improve the sealing performance when closed. In addition, an antistatic light-shielding film (light transmittance <0.1%) is attached to the inner side of the anti-interference baffles 18. Torsion springs 19 are connected between the front and rear sides of the anti-interference baffles 18 and the corresponding support blocks 17 to provide closing torque for the anti-interference baffles 18. The detection cavity 3 is provided with control components for linkage control of the opening and closing of the anti-interference baffles 18.

[0023] like Figure 3As shown, the control assembly includes a sliding frame 15 and a return spring 16. The sliding frame 15 is slidably connected to the front and rear sides of the detection cavity 3 near the support block 17. The return spring 16 is connected between the sliding frame 15 and the detection cavity 3. The outer end of the sliding frame 15 abuts against the anti-interference baffle 18 on the corresponding side, forcing it to remain in the open state. At this time, the torsion spring 19 is in the energy storage (deformation) state. The inner end of the sliding frame 15 is machined with a guide slope, which is in contact with the clamping arm 12. At this time, the return spring 16 is in the stretched state.

[0024] When the sample arrives at the workstation and the clamping arm 12 moves inward to clamp the sample, the clamping arm 12 disengages from the inclined surface of the sliding frame 15. The elastic restoring force of the reset spring 16 drives the sliding frame 15 to move radially outward along the detection cavity 3, releasing the constraint on the anti-interference baffle 18. The torsion spring 19 then releases its stored energy to drive the anti-interference baffle 18 to rotate downward and close the inlet and outlet, isolating external light interference. The detection cavity 3 is illuminated by the lighting lamp 6. When the sample detection is completed and the clamping arm 12 moves outward to reset, the clamping arm 12 contacts and presses the guide inclined surface of the sliding frame 15, pushing the sliding frame 15 to move radially inward and stretching the reset spring 16 to store energy. The outer end of the sliding frame 15 pushes the anti-interference baffle 18 to rotate upward and open the inlet and outlet. At the same time, the torsion spring 19 deforms again to store energy.
