Description

Technical Field

[0001] This invention relates to the field of product appearance inspection technology, specifically a 360-degree rotating inspection mechanism for product appearance internal support positioning. Background Technology

[0002] When processing electronic products, it is usually necessary to inspect the appearance defects of the products. In order to improve the stability of the products during inspection, positioning mechanisms are often used to internally support and position the products to be inspected, thereby avoiding the clamping parts from affecting the product appearance inspection.

[0003] For example, the Chinese patent with announcement number CN220584038U, patent name: Product Appearance Inspection Machine, and announcement date: 2024-03-12 includes a machine base and a CCD camera. The CCD camera is mounted on the machine base and electrically connected to a PLC. The machine base is equipped with a lifting mechanism for raising and lowering the CCD camera. A light source is provided below the CCD camera. The machine base is equipped with a horizontal linear movement mechanism. The horizontal linear movement mechanism is equipped with a product swing mechanism that drives the product to swing in a vertical plane. The product swing mechanism is equipped with a product rotation mechanism that drives the product to rotate axially.

[0004] The existing technologies mentioned above have the following technical problems: When conducting appearance inspections on products, existing testing institutions use clamping components and rotating mechanisms to rotate the clamped product, thereby achieving all-round inspection. However, during positioning, it is not convenient to clean impurities attached to the product surface. When impurities are attached to the product surface, it is easy to cause misjudgments in appearance inspection. At the same time, some testing institutions set up separate cleaning stations to facilitate product cleaning. Although these stations can also clean the product surface, the integration is poor, and separate drive mechanisms, such as cylinders or motors, are required to provide power. For product processing lines, too many electrical devices and pipelines will occupy too much space, and separate cleaning stations will also reduce the efficiency of product inspection and processing.

[0005] Therefore, we proposed a 360-degree rotating detection mechanism for product appearance internal support positioning to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a 360-degree rotating inspection mechanism for product appearance internal support positioning, in order to solve the problems mentioned in the background art. Currently, existing inspection mechanisms on the market, when performing appearance inspections, use clamping components and rotating mechanisms to rotate the clamped product for omnidirectional inspection. However, during positioning, it is inconvenient to clean impurities adhering to the product surface. When impurities are attached to the product surface, it can easily lead to misjudgments in appearance inspection. Furthermore, some inspection mechanisms set up separate cleaning stations for easier product cleaning. While these stations can clean the product surface, their integration is poor, requiring separate drive mechanisms, such as cylinders or motors, to provide power. For product processing lines, excessive electrical equipment and pipelines occupy too much space, and separate cleaning stations also reduce product inspection and processing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a 360-degree rotating detection mechanism for product appearance internal support positioning, comprising a positioning seat and a servo motor mounted on the positioning seat, wherein the output end of the servo motor is connected to a coupling, a connecting slip ring is connected above the coupling, and a power cylinder is fixed at the upper end of the connecting slip ring, a support seat is connected to the fixed end of the power cylinder, a movable rod is connected to the telescopic end of the power cylinder, and a pressing block is connected to the end of the movable rod, guide sliders are provided on the left and right sides of the pressing block, and the guide sliders are mounted on a limiting rod fixed on the support seat, the guide sliders are connected to the support seat through an auxiliary spring, an inner support block is mounted on the guide slider, the inner support block is used for internal support positioning of the product to be tested, the pressing block and the movable rod are connected to each other through a built-in spring, and a lifting rod is fixed to the side of the movable rod, the lifting rod is used to push the cleaning component on the guide slider.

[0008] Preferably, the upper outer wall of the movable rod and the inner wall of the extrusion block are in contact with each other, and the stiffness coefficient of the built-in spring between the movable rod and the extrusion block is greater than the stiffness coefficient of the auxiliary spring.

[0009] By adopting the above technical solution, when the movable rod pushes the extrusion block to move, the extrusion block can first push the guide slider to move, thereby causing the auxiliary spring to deform first.

[0010] Preferably, the guide slider is provided with an inner groove that matches the slope of the extrusion block surface, and the longitudinal section of the extrusion block is set as an isosceles trapezoidal structure, and the guide slider can slide on the limiting rod.

[0011] By adopting the above technical solution, when the extrusion block moves upward, it can use the inclined surface to extrude the inner groove on the guide slider, thereby pushing the guide slider to move on the limit rod.

[0012] Preferably, the longitudinal section of the lifting rod is set to an "L" shape, and the lifting rod can slide on the guide slider.

[0013] By adopting the above technical solution, the upward movement of the lifting rod can push the cleaning component on the guide slider upward, thereby cleaning the impurities attached to the product surface by the movement of the cleaning component.

[0014] Preferably, the cleaning component includes a cleaning block embedded in the guide slider, and the cleaning block is connected to the guide slider by a reset spring. A cleaning pad is fixed to the end of the cleaning block facing the product, and a piston plate is inserted inside the cleaning block. The piston plate is connected to the end of the cleaning block away from the product by an adjusting spring, and an air vent is provided at the end of the cleaning block facing the product.

[0015] By adopting the above technical solution, the cleaning block can be reset and rebound after moving on the guide slider by setting the reset spring.

[0016] Preferably, the cleaning block and the guide slider are slidably connected, and the upper surface of the cleaning block and the upper surface of the guide slider are flush with each other.

[0017] By adopting the above technical solution, the upper surface of the cleaning block and the upper surface of the guide slider are flush with each other, thereby avoiding the cleaning block from obstructing part of the product.

[0018] Preferably, the end of the piston plate that extends into the cleaning block forms a seamless sliding connection structure with the cleaning block through a circumferentially wrapped sealing ring, and the interior of the cleaning block is set as a hollow structure.

[0019] By adopting the above technical solution, the sealing performance of the piston plate can be improved when it moves on the cleaning block through the circumferential sealing ring at the end of the piston plate.

[0020] Preferably, the cleaning block has multiple air vents evenly distributed at the end near the test product, and the air vents are located above the cleaning pad.

[0021] By adopting the above technical solution, air can be blown toward the surface of the product to be tested through the setting of the air outlet, thereby reducing the adhesion of impurities on the product surface.

[0022] Preferably, a supplementary light is installed at the end of the guide slider, and the longitudinal section of the supplementary light is set as an inverted isosceles trapezoidal structure, and the end of the piston plate near the supplementary light is set as an arc.

[0023] By adopting the above technical solution, the supplementary light can provide illumination around the product during appearance inspection, and the inclined surface of the supplementary light can be used to squeeze the arc-shaped end of the piston plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the product appearance internal support positioning 360-degree rotating detection mechanism, by integrating the cleaning mechanism on the clamping component, uses the cylinder to clamp while controlling the cleaning component to clean the surface of the product to be tested, integrating cleaning and clamping, avoiding the need to set up a separate cleaning station, saving processing line space, and improving detection and processing efficiency;

[0025] 1. It is equipped with an inner support block. The movement of the movable rod and the pressing block can push the guide slider to move outward towards the support base. After the guide slider moves, it can drive the inner support block to move synchronously. The movement of the inner support block can be used to internally support and position the product. At the same time, the servo motor can be used to control the rotation of the clamped product. The rotation of the product can achieve all-round inspection.

[0026] 2. A cleaning stop is provided. After the guide slider moves to the limit, the extrusion block can no longer be pushed. At this time, the movable rod moves on the extrusion block. After the movable rod moves, it can push the cleaning stop upward. After the cleaning stop moves, the impurities attached to the product surface can be cleaned. The clamping and cleaning components are combined by the integrated design, which saves the space of the processing production line, avoids the need to set up a separate cleaning station, and improves the overall processing and inspection efficiency.

[0027] 3. It is equipped with a supplementary light. The supplementary light can increase the brightness around the product during product appearance inspection. At the same time, after the cleaning block moves upward, the arc-shaped end of the piston plate is squeezed by the inclined surface of the supplementary light. After being pressed, the piston plate moves towards the inside of the cleaning block. After the piston plate moves, it can squeeze the airflow inside the cleaning block out through the air outlet. The squeezed airflow can reduce the adhesion of impurities on the product surface. Attached Figure Description

[0038] 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.

[0039] Example 1: Please refer to Figures 1-9Existing testing institutions use clamping and rotating mechanisms to rotate clamped products during appearance inspection, enabling omnidirectional testing. However, this method is inconvenient for cleaning impurities adhering to the product surface during positioning. Impurities on the product surface can easily lead to misjudgments in appearance inspection. Furthermore, some testing institutions set up separate cleaning stations for easier cleaning, which, while capable of cleaning the product surface, suffer from poor integration and require independent drive mechanisms, such as cylinders or motors. For product processing lines, excessive electrical equipment and wiring can consume significant resources. Excessive space usage and separate cleaning stations can reduce product inspection and processing efficiency. To address this technical problem, this embodiment discloses the following technical content: a 360-degree rotating inspection mechanism for product appearance internal support positioning, including a positioning base 1 and a servo motor 2 mounted on the positioning base 1. The output end of the servo motor 2 is connected to a coupling 3, and a connecting slip ring 4 is connected above the coupling 3. A power cylinder 5 is fixed to the upper end of the connecting slip ring 4. A support base 6 is connected to the fixed end of the power cylinder 5. A movable rod 7 is connected to the telescopic end of the power cylinder 5, and a pressing block 8 is connected to the end of the movable rod 7. Guides are provided on the left and right sides of the pressing block 8. The guide slider 9 is mounted on a limiting rod 10 fixed to a support base 6. The guide slider 9 is connected to the support base 6 via an auxiliary spring 11. An inner support block 12 is mounted on the guide slider 9 for internal support and positioning of the product to be tested. The squeezing block 8 and the movable rod 7 are connected to each other via a built-in spring 13. A lifting rod 14 is fixed to the side of the movable rod 7 for pushing the cleaning components on the guide slider 9. The upper outer wall of the movable rod 7 and the inner wall of the squeezing block 8 are in contact with each other. The stiffness coefficient of the built-in spring 13 between the movable rod 7 and the squeezing block 8 is greater than that of the auxiliary spring 11. The guide slider 9 is equipped with... The extrusion block 8 has an inner groove that matches the slope of its surface. The longitudinal section of the extrusion block 8 is set as an isosceles trapezoidal structure. The guide slider 9 can slide on the limiting rod 10. The longitudinal section of the lifting rod 14 is set as an "L" shape. The lifting rod 14 can slide on the guide slider 9. The cleaning component includes a cleaning stop 15 embedded in the guide slider 9. The cleaning stop 15 is connected to the guide slider 9 through a return spring 16. A cleaning pad 17 is fixed to the end of the cleaning stop 15 facing the product. The cleaning stop 15 and the guide slider 9 are slidably connected. The upper surface of the cleaning stop 15 is flush with the upper surface of the guide slider 9.

[0040] When a product needs to undergo visual inspection, a robotic arm places the product onto two inner support blocks 12. Then, the power cylinder 5 is activated, causing the movable rod 7 and the pressing block 8 to move upwards. Because the spring coefficient of the built-in spring 13 between the movable rod 7 and the pressing block 8 is greater than that of the auxiliary spring 11, the pressing block 8 first pushes the guide slider 9 to move. After the guide slider 9 moves outwards from the support base 6, it drives the inner support blocks 12 to move synchronously. The movement of the inner support blocks 12 provides internal support and positioning for the product. After the product is fixed, the power cylinder 5 continues to push the movable rod 7 and the pressing block 8 to move synchronously. Since the upward movement of the pressing block 8 can no longer push the guide slider 9, the movable rod 7 can move on the pressing block 8, causing the built-in spring... When spring 13 is elastically compressed, the movable rod 7 moves upward, which pushes the cleaning block 15 on the guide slider 9 to move upward synchronously. After the cleaning block 15 moves upward, the cleaning pad 17 on it can effectively wipe away the impurities attached to the product surface. After cleaning the product, the power cylinder 5 controls the movable rod 7 to retract. After the movable rod 7 returns to its original position, the lifting rod 14 releases the push on the cleaning block 15. The cleaning block 15 also returns to its original position under the action of the return spring 16, preventing the cleaning block 15 from obstructing the product during inspection. During the inspection process, the servo motor 2 is turned on. After the servo motor 2 is turned on, the power cylinder 5 can be rotated by the coupling 3 and the connecting slip ring 4. The rotation of the power cylinder 5 can drive the product fixed by the internal support to rotate synchronously, thereby realizing all-round inspection of the product surface appearance.

[0041] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figure 1 , Figure 6 , Figure 8 and Figure 9 As shown, a piston plate 18 is inserted inside the cleaning block 15. The piston plate 18 is connected to the end of the cleaning block 15 away from the product via an adjusting spring 19. An air vent 20 is provided at the end of the cleaning block 15 facing the product. The end of the piston plate 18 extending into the cleaning block 15 forms a seamless sliding connection structure with the cleaning block 15 through a circumferentially wrapped sealing ring. The interior of the cleaning block 15 is hollow. Multiple air vents 20 are evenly distributed at the end of the cleaning block 15 near the product being inspected. The air vents 20 are located above the cleaning pad 17. A supplementary light 21 is installed at the end of the guide slider 9. The longitudinal section of the supplementary light 21 is an inverted isosceles trapezoidal structure. The end of the piston plate 18 near the supplementary light 21 is arc-shaped.

[0042] When the lifting rod 14 moves upward, it can push the cleaning block 15 upward. After the cleaning block 15 moves upward, the piston plate 18 can move synchronously. When the piston plate 18 moves upward, its arc-shaped end can gradually come into contact with the inclined side of the supplementary light 21. At this time, the inclined side of the supplementary light 21 presses the arc-shaped end of the piston plate 18. After being pressed, the piston plate 18 can move on the cleaning block 15. Because the cleaning pad 17 on the cleaning block 15 is in contact with the product surface, the movement of the piston plate 18 will not drive the cleaning block 15 to move synchronously. After the piston plate 18 moves, the airflow inside the cleaning block 15 can be sprayed out towards the product surface through the air outlet 20. The sprayed airflow can be used to reduce the adhesion of impurities on the product surface, making it easier for the cleaning pad 17 on the cleaning block 15 to better scrape off the impurities. When inspecting the appearance of the product, the supplementary light 21 can also be turned on to provide light around the product during the appearance inspection.
