Description

Technical Field

[0001] This invention relates to the field of dashboard quality testing technology, specifically a testing machine for automotive dashboard quality testing. Background Technology

[0002] In the production process of automotive instrument panels, illumination inspection is a crucial quality control step, used to detect display defects (such as dead pixels, uneven brightness, etc.). Currently, due to the immaturity of AOI (Automated Optical Inspection) technology, manual re-inspection is still necessary in actual testing. In AOI mode, because a camera is used for imaging, if the instrument panel and the polarizing plate are too close, the camera may misinterpret dust or foreign objects on the polarizing plate as panel defects; therefore, a larger distance must be maintained. However, in manual inspection mode, if the distance is too large, factors such as ambient light may interfere with the inspection accuracy, affecting the detection rate of defective products.

[0003] Existing automotive dashboard inspection devices, such as the defect detection device for automotive dashboard panels proposed in patent application number "CN118275459B", relate to the field of physical analysis technology. This invention, with its uniform distribution and elastic design of multiple mounting cylinders, ensures stable support for the panel, driving multiple winding rollers to wind up the wire and pull the moving seat within the assembly cylinder. During the initial movement of the moving seat, air is drawn from the assembly cylinder, creating a vacuum negative pressure on one side of the dashboard panel. Combined with the fixing components, this further stabilizes the dashboard panel. When the negative pressure exceeds the resistance of the reset components, the dashboard panel can be driven close to the polarizer for subsequent inspection. By controlling the distance between the dashboard panel and the polarizer, both AOI inspection and manual fixing inspection can be achieved, improving the system's flexibility and applicability. Simultaneously, the moving frame can quickly return to its original position after inspection, reducing the need for manual operation.

[0004] However, in actual use, this instrument panel testing device has a significant operational problem: the return spring continuously applies a restoring force to the rotating rod, causing the connecting arm to remain in its initial closed state. This design feature directly obstructs panel insertion, requiring operators to manually pull the connecting arm to insert the panel smoothly. This forced manual intervention not only increases the number of steps but also severely impacts overall testing efficiency. Summary of the Invention

[0017] The beneficial effects of this invention are:

[0018] 1. This invention involves stacking multiple instrument panel units horizontally inside a hopper. A camera module captures and inspects images of the instrument panel unit closest to the inspection port. A manually rotated drive mechanism moves a light-changing plate along the length of a push-out slide rod towards the inspection port. This shortens the distance between the light-changing plate and the instrument panel unit, facilitating manual observation of the instrument panel surface. After inspection, the force applied to the drive mechanism is released. Simultaneously, a transmission mechanism works to move the instrument panel unit closest to the inspection port to a discharge port. At the same time, a self-inspection mechanism reads the inspection data from the camera module and removes the inspected instrument panel unit through the discharge port from the hopper for the next process. The entire inspection process eliminates the need for manual fixing of the instrument panel units, effectively reducing manual intervention, automating the inspection process, and significantly improving inspection efficiency and operational convenience.

[0019] 2. This invention drives the adjusting gear to rotate by turning the adjusting handle around the hinge axis. Utilizing the meshing transmission and circumference difference between the adjusting gear and the speed-increasing gear, transmission efficiency is improved, thereby driving the ejector gear and ejector rack to rotate synchronously. During this process, the ejector gear drives the ejector slide rod to move linearly along the length of the feeding chute, causing the ejector slide rod to move the brightness-changing plate closer to one end of the detection port, shortening the distance between the brightness-changing plate and the instrument panel, facilitating manual observation of the instrument panel surface. This design, through optimizing the gear transmission structure, achieves efficient and stable distance adjustment, significantly improving the detection accuracy of the instrument panel, while reducing the complexity of manual operation and enhancing the overall performance of the device.

[0020] 3. In this invention, when the drive plate moves linearly along the length of the ejector slide, the reset baffle applies pressure to the reset spring, causing the reset spring to contract and store elastic potential energy. Then, when the manual operation of the drive mechanism stops applying force to the ejector slide, the spring's rebound characteristic pushes the reset baffle, which in turn pulls the ejector slide away from the instrument panel, completing the automatic reset. By utilizing the energy storage and rebound characteristics of the reset spring, this invention achieves precise linear movement and automatic reset of the beam shifter, reducing manual intervention, lowering operational complexity, significantly reducing the workload of operators, and improving the device's detection efficiency and ease of operation.

[0021] 4. This invention uses a manually rotated wrench to adjust the handle, which drives the adjusting gear to rotate the ratchet gear. This rotation causes the ratchet rack to compress the contact spring, resulting in deformation. The rebound force of the contact spring then pushes the ratchet rack out, re-engaging it with the ratchet gear. After releasing the pressure on the drive mechanism, the return spring rebounds, causing the ratchet gear to rotate and pushing the ratchet rack to move the L-shaped feeding slide along the feeding chute. This, in turn, pushes the feeding push plate and multiple instrument panel panels forward, moving the instrument panel closest to the detection port to the unloading port side. This achieves automatic feeding, simplifies the operation process, reduces manual intervention, and significantly improves detection efficiency and automation. Attached Figure Description

[0033] 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.

[0034] A quality inspection and testing machine for automotive dashboards is used for the automated detection of display defects (such as dead pixels, uneven brightness, etc.) on automotive dashboard panels. Figure 1 As shown, the dimming plate 10 integrates a camera module 11. The driving mechanism drives the dimming plate 10 to move linearly along the length of the ejector slide rod 9, shortening the distance between it and the instrument panel 12, which facilitates manual or AOI inspection. This belongs to the field of instrument panel inspection technology.

[0035] like Figures 1-5 As shown, it includes a feeding platform 1, a monitoring platform 2 fixedly connected to one end of the feeding platform 1, a hopper 3 opened on the top of the feeding platform 1, a detection port 4 communicating with the inside of the hopper 3 opened at one end of the feeding platform 1, a feeding chute 5 communicating with the inside of the monitoring platform 2 opened at the bottom of the hopper 3, an L-shaped feeding slide rod 6 slidably connected inside the feeding chute 5, a feeding push plate 7 fixedly connected to one end of the L-shaped feeding slide rod 6, and the feeding push plate 7 installed inside the hopper 3;

[0036] One end of the monitoring station 2 is provided with an adjustment sliding hole 8. An ejector slide rod 9 is slidably connected inside the adjustment sliding hole 8. One end of the ejector slide rod 9 is fixedly connected to a light-changing plate 10. The light-changing plate 10 integrates a camera module 11. The camera module 11 includes a set of Basler ace acA1 920-40gm cameras and an LED light that provides uniform illumination.

[0037] The hopper 3 is equipped with an instrument panel 12 that is compatible with the feeding push plate 7, and the hopper 3 has a discharge port 31 at the end near the detection port 4.

[0038] The monitoring station 2 is equipped with a drive mechanism for driving the light-changing plate 10 to move along the length of the ejector slide rod 9, and a transmission mechanism for driving the feeding push plate 7 to move along the length of the feeding chute 5 is installed at one end of the monitoring station 2. The feeding station 1 is equipped with a self-testing mechanism for cooperating with the camera module 11 to complete the surface inspection of the instrument panel 12.

[0039] In use, multiple instrument panel 12 are first stacked horizontally inside the hopper 3. Simultaneously, the camera module 11, with its built-in LED lights, provides uniform illumination to the instrument panel 12. The built-in Basler AceacA1 920-40gm camera captures and detects an instrument panel 12 near the detection port 4. Then, the drive mechanism is manually rotated to move the component dimming plate 10 along the length of the component ejection slide rod 9 towards the detection port 4, thereby shortening the distance between the dimming plate 10 and the instrument panel 12. The distance between the two ports facilitates manual observation of the instrument panel 12 surface. After the inspection is completed, the force applied to the drive mechanism is released. At the same time, the transmission mechanism works in coordination to push the instrument panel 12 closest to the inspection port 4 to the side discharge port 31. Meanwhile, the self-inspection mechanism reads the inspection data of the camera module 11 and moves the inspected instrument panel 12 out of the hopper 3 through the discharge port 31 to enter the next process. In this way, when inspecting the instrument panel 12, there is no need to manually fix the instrument panel 12, which effectively reduces manual intervention and improves the inspection efficiency of the device.

[0040] like Figures 3-6 As shown, the drive mechanism includes an ejection rack 13 fixedly connected to one end of the ejection slide rod 9, an ejection gear 14 that meshes with the ejection rack 13 is rotatably connected inside the monitoring platform 2, and a drive assembly is installed inside the monitoring platform 2.

[0041] The drive assembly includes a speed-increasing gear 15 fixedly connected to one end of the ejector gear 14, and an adjusting gear 16 that meshes with the speed-increasing gear 15 is rotatably connected inside the monitoring station 2. One end of the adjusting gear 16 extends to the outside of the monitoring station 2 and is fixedly connected to an adjusting handle 17.

[0042] In use, the adjusting handle 17 is first moved around the hinge axis, causing the adjusting handle 17 to drive the adjusting gear 16 to rotate. As the adjusting gear 16 rotates, it meshes with the speed-increasing gear 15, thereby causing the speed-increasing gear 15 and its fixedly connected ejector gear 14 to rotate synchronously. Simultaneously, the difference in circumference between the adjusting gear 16 and the speed-increasing gear 15 improves the transmission efficiency between the adjusting gear 16 and the ejector gear 14. Since the ejector gear 14 also meshes with the ejector rack 13, the rotation of the ejector gear 14 drives the ejector rack 13 and its connected ejector slide rod 9 to move linearly along the length of the feeding chute 5. At the same time, the ejector slide rod 9 drives the brightening plate 10 to move along the length of the feeding chute 5 towards one end of the detection port 4, shortening the distance between the brightening plate 10 and the instrument panel 12, facilitating manual observation of the instrument panel 12 surface, and effectively improving the detection accuracy of the instrument panel 12.

[0043] like Figures 2-4 , Figure 6 As shown, a guide slide rod 18 is fixedly connected to one end of the light-changing plate 10, and a guide slide hole 19 adapted to the guide slide rod 18 is opened at one end of the monitoring platform 2;

[0044] Among them, a reset baffle 24 is fixedly connected to one end of the ejector slide rod 9 and the guide slide rod 18, and a reset spring 25 is sleeved on one end of the ejector slide rod 9. The reset spring 25 is installed between the monitoring platform 2 and the reset baffle 24.

[0045] Furthermore, a T-shaped limiting collar 26 is fixedly connected to one end of both the monitoring station 2 and the reset baffle 24. The two T-shaped limiting collars 26 are arranged in parallel and opposite directions, and the reset spring 25 is fixedly sleeved around the two T-shaped limiting collars 26.

[0046] Furthermore, a positioning collar 30 is fixedly sleeved on one end of the guide slide rod 18.

[0047] In use, the drive mechanism is first manually operated to move the brightening plate 10 along the length of the ejector slide rod 9. At this time, the brightening plate 10 pulls one end of the guide slide rod 18 through the guide slide hole 19, and the guide slide rod 18 precisely controls the movement trajectory of the brightening plate 10, ensuring that the brightening plate 10 moves along the straight ejector slide rod 9 and preventing rotational deviation. Next, when the brightening plate 10 pulls the guide slide rod 18 to move a predetermined distance along the ejector slide rod 9, the guide slide rod 18 pushes the positioning collar 30 to contact the monitoring platform 2, limiting the range of movement of the brightening plate 10 along the ejector slide rod 9, ensuring that the distance the brightening plate 10 moves along the ejector slide rod 9 is consistent each time it is manually driven, thereby improving the accuracy of manual detection. Simultaneously, as the brightening plate 10 moves towards the instrument panel 12 along the length of the ejector slide rod 9 and moves in a straight line, it drives the reset baffle 24 to apply pressure to the reset spring 25, causing the reset spring 25 to contract and deform, storing elastic potential energy. Subsequently, when the manual drive mechanism ceases to apply thrust to the ejector slide 9, the rebound characteristic of the return spring 25 is activated, pushing the return baffle 24 to move the ejector slide 9 linearly along the length of the guide slide 18, and causing the dimming plate 10 to move away from the instrument panel 12 along the ejector slide 9, thus completing the automatic reset of the dimming plate 10. Furthermore, during the contraction or rebound extension of the return spring 25, the contact between the T-shaped limiting collar 26 and the inner wall of the return spring 25 reduces bending of the return spring 25 and avoids interference with the ejector rack 13. These measures further reduce manual intervention, alleviate the workload of workers, and improve the detection efficiency of the device.

[0048] like Figure 4 and Figure 5 , Figure 7 , Figure 8As shown, the transmission mechanism includes a receiving groove 20 opened at one end of the L-shaped feeding slide bar 6. A ratchet rack 21 is slidably connected inside the receiving groove 20. Multiple abutment springs 22 are evenly fixedly connected to the bottom of the ratchet rack 21. The abutment springs 22 are installed between the ratchet rack 21 and the receiving groove 20. A ratchet gear 23 is fixedly connected to one end of the adjusting gear 16. The ratchet gear 23 meshes with the ratchet rack 21. A self-locking component for positioning the L-shaped feeding slide bar 6 is installed inside the feeding groove 5.

[0049] The self-locking component includes an installation groove 27 at one end of the feeding chute 5. A triangular self-locking block 28 is hinged inside the installation groove 27. A self-locking spring 33 is symmetrically fixedly connected to one end of the triangular self-locking block 28. The self-locking spring 33 is fixedly connected to the inner wall of the installation groove 27. A self-locking groove 34 adapted to the triangular self-locking block 28 is provided on one side of the L-shaped feeding slide rod 6.

[0050] In use, first, manually rotate the wrench adjustment handle 17 to drive the adjustment gear 16 to rotate, which in turn causes the adjustment gear 16 to rotate the ratchet 23 synchronously, ensuring that the ratchet 23 meshes with the ratchet rack 21. Simultaneously, the ratchet 23 pushes the ratchet rack 21 to compress the abutment spring 22, causing it to contract and deform. One end of the ratchet rack 21 embeds into the receiving groove 20, and the ratchet 23 continues to rotate. When the ratchet 23 stops rotating, the rebound force of the abutment spring 22 pushes the ratchet rack 21 out and pushes it to re-mesh with the ratchet 23. Then, after manually releasing the pressure on the drive mechanism, the ratchet 23 begins to rotate, meshing with the ratchet rack 21 and pushing the ratchet rack 21 to move the L-shaped feeding slide rod 6 a short distance along the length of the feeding groove 5. Simultaneously, the L-shaped feeding slide bar 6 pushes the feeding push plate 7 along the inner wall of the hopper 3, moving multiple instrument panel 12 forward a short distance, so that the instrument panel 12 closest to the detection port 4 moves to the side of the discharge port 31. By operating the drive mechanism, the brightness plate 10 moves linearly back and forth along the ejection slide bar 9 towards the detection port 4, pushing multiple instrument panel 12 forward sequentially along the inner wall of the hopper 3, and moving the instrument panel 12 closest to the brightness plate 10 to the side of the discharge port 31, thus achieving automatic feeding of the instrument panel 12 and effectively improving the detection efficiency of the device.

[0051] Furthermore, while the ratchet 21 drives the L-shaped feeding slide 6 to move along the length of the feeding groove 5, one end of the L-shaped feeding slide 6 comes into contact with the triangular self-locking block 28, pushing the triangular self-locking block 28 to squeeze the self-locking spring 33 around the hinge axis. This causes the self-locking spring 33 to contract and deform, accumulating elastic potential energy. At the same time, it drives one end of the triangular self-locking block 28 into the mounting groove 27. Then, when the L-shaped feeding slide 6 moves a short distance along the length of the feeding groove 5 and stops moving, the elastic potential energy of the self-locking spring 33 is released. Simultaneously, it pushes out the triangular self-locking block 28 around the hinge axis, thereby causing one end of the triangular self-locking block 28 to embed into the self-locking groove 34, thus achieving a high lock on the L-shaped feeding slide 6 and improving the practicality of the device.

[0052] like Figure 1 and Figure 2 , Figure 9 As shown, the self-inspection mechanism includes a self-inspection panel 35 fixedly connected to one end of the loading platform 1, a manual switch 36 fixedly connected to one end of the adjustment handle 17, the self-inspection panel 35 being electrically connected to the camera module 11 and the manual switch 36, a conveyor belt 37 being provided on the top of the loading platform 1, and a transfer frame 38 being fixedly connected to one end of the loading platform 1, one end of the transfer frame 38 being installed above the conveyor belt 37 and extending to one side of the detection port 4, a transfer slide rail 39 being provided on the top of the transfer frame 38, a transfer slider 40 being slidably connected inside the transfer slide rail 39, an adjustment groove 41 being provided at one end of the transfer slider 40, a mounting frame 42 being slidably connected inside the adjustment groove 41, an automatic suction cup 43 being fixedly connected to the bottom of the mounting frame 42, and a feeding component being installed at one end of the transfer frame 38 for driving the mounting frame 42 to move along the length direction of the transfer slide rail 39;

[0053] The feeding assembly includes a transfer screw 44 rotatably connected inside the transfer slide rail 39, a transfer motor 45 fixedly connected to one end of the transfer frame 38, the output end of the transfer motor 45 fixedly connected to the transfer screw 44, a trapezoidal guide rod 46 fixedly connected to one end of the transfer frame 38, an abutting slide rod 47 rotatably connected to one end of the mounting frame 42 that abuts against the trapezoidal guide rod 46, and lifting springs 48 symmetrically fixedly connected inside the adjusting slide groove 41, with the top of the lifting springs 48 fixedly connected to the mounting frame 42.

[0054] In use, the camera module 11 first uses built-in LED lights to provide uniform illumination for the dashboard panel 12. At the same time, the built-in Basler ace acA1920-40gm camera collects and detects images of one dashboard panel 12 near the detection port 4. The detection data from the camera module 11 is then provided to the operator through the self-test panel 35. The operator compares the surface condition of the dashboard panel 12 observed by the operator with the data provided by the self-test panel 35. If the operator believes that the surface condition of the dashboard panel 12 is unqualified and differs from the detection result provided by the self-test panel 35, the operator can press the manual switch 36 to change the detection result provided by the self-test panel 35. Meanwhile, the self-test panel 35 has a built-in decision chip. After the dashboard panel 12 is detected, the transfer motor 45 is started, so that the output end of the transfer motor 45 drives the transfer screw 44 to rotate.

[0055] As the transfer screw 44 rotates, the transfer slider 40, which is threaded to it, slides along the length of the transfer slide rail 39. At this time, the contact slide bar 47 deflects under the guidance of the trapezoidal guide rod 46, thereby driving the mounting bracket 42 to slide along the inside of the adjusting slide groove 41. Simultaneously, the lifting spring 48 contracts and deforms, providing power for the mounting bracket 42 to reset. As the transfer slider 40 moves, the automatic suction cup 43 at the bottom of the mounting bracket 42 moves to one side of the detection port 4, and under the guidance of the trapezoidal guide rod 46, pushes the automatic suction cup 43 toward the instrument panel 12 and adheres to the surface of the instrument panel 12 after the detection is completed. Subsequently, the transfer motor 45 is started in reverse. The output end of the transfer motor 45 drives the transfer screw 44 to rotate in the opposite direction, causing the transfer slider 40 to move in the opposite direction along the length of the transfer slide rail 39. Then, when the automatic suction cup 43 drives the instrument panel 12 through the discharge port 31 and out of the inside of the hopper 3, the lifting spring 48 releases its elastic potential energy, pushing the mounting frame 42 to move in the opposite direction along the inside of the adjusting slide 41. This, in turn, drives the automatic suction cup 43 to move the inspected instrument panel 12 along the transfer frame 38 to the top of the conveyor belt 37. Then, the automatic suction cup 43 releases its suction force, causing the inspected instrument panel 12 to fall onto the surface of the conveyor belt 37 and be conveyed by the conveyor belt 37 to the next process. In this way, the automatic unloading of the inspected instrument panel 12 is realized, further reducing manual intervention and improving the inspection efficiency of the device.

[0056] The working principle of the automotive dashboard quality inspection and testing machine provided by this invention is as follows:

[0057] In use, multiple instrument panel 12 are first stacked horizontally and placed into the hopper 3. During the inspection phase, the instrument panel 12 closest to the inspection port 4 is image-captured and inspected by the camera module 11. The camera module 11 is embedded in the dimmer plate 10 and uses built-in LEDs to provide uniform illumination for the instrument panel 12. Simultaneously, the built-in Basler Aceac A1 920-40gm camera accurately inspects the surface of the instrument panel 12 and transmits the data to the self-test panel 35 for analysis. Then, by manually rotating the adjustment handle 17, the adjustment gear 16 is driven to rotate. The adjustment gear 16 meshes with the speed-increasing gear 15, driving the ejector gear 14 to rotate through the gear transmission mechanism, thereby causing the ejector rack 13 to move linearly along the length of the feeding chute 5. The ejector rack 13 and the ejector slide bar 9 are fixedly connected, which will push the brightening plate 10 to move towards the detection port 4, thereby shortening the distance between the brightening plate 10 and the instrument panel 12, making it easier for manual observation of the surface of the instrument panel 12.

[0058] After the test is completed, release the adjustment handle 17. The reset spring 25 releases its elastic potential energy, pushing the dimming plate 10 back to its original position away from the panel. At the same time, the ratchet 23 of the transmission mechanism meshes with the ratchet rack 21, driving the L-shaped feeding slide 6 to push the feeding push plate 7 to the unloading port 31. The self-locking component locks the position of the slide by cooperating with the triangular self-locking block 28 and the self-locking groove 34, ensuring stable pushing.

[0059] In the final unloading stage, the staff compares the observation results with the test data provided by the self-inspection panel 35, and modifies any discrepancies in the self-inspection panel results by pressing the manual switch 36. Then, the transfer motor 45 starts, driving the transfer screw 44 to move the transfer slider 40. The automatic suction cup 43 at the bottom of the mounting bracket 42 picks up the tested instrument panel 12 and transfers it along the transfer slide rail 39 to the conveyor belt 37. The lifting spring 48 and the trapezoidal guide rod 46 work together to adjust the height of the automatic suction cup 43, ensuring that the automatic suction cup 43 stably picks up the instrument panel 12 for transfer to the next process. The entire process, through the synergy of mechanical transmission, elastic reset, and automated control, achieves continuous feeding, accurate testing, and automatic unloading of instrument panels, significantly reducing manual intervention and improving testing efficiency and accuracy.
