Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, specifically an automatic dust removal inspection device. Background Technology

[0002] Silicone rubber seals have excellent heat resistance, sealing performance and insulation properties, and are widely used in electronics, home appliances, automobiles, medical and other fields. They are key components to ensure product assembly accuracy and reliability. In the automated production process of silicone rubber seals, appearance, size and surface defect detection are important links in quality control. At present, the industry mostly uses vision inspection devices to complete automated quality inspection.

[0003] However, during the molding, cutting, and transportation processes, silicone rubber seals are prone to adsorbing dust and debris on their surface. Furthermore, silicone rubber itself has a certain degree of stickiness and electrostatic adsorption properties, making it difficult for tiny impurities to fall off naturally. If these impurities are directly introduced into the visual inspection process, they will seriously interfere with the accuracy of image acquisition and defect identification. Currently, the quality inspection devices used for silicone rubber seals generally suffer from problems such as poor dust removal, unstable conveying posture, and insufficient versatility, which cannot meet the requirements for high-precision quality inspection. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to improve the dust removal effect and efficiency of silicone rubber sealing rings, and to this end, an automatic dust removal quality inspection device is provided.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic dust-removing quality inspection device, comprising a machine body, a feeding unit, a hopper, a discharging unit, and a dust removal mechanism. A turntable is installed inside the machine body, and a conveyor belt and a vision inspection system are installed outside the turntable. The feed end of the conveyor belt is aligned with the discharge end of the feeding unit, and the workpiece falls smoothly from the feeding unit onto the conveyor belt. A groove is provided on the conveyor belt, and a first support frame and a second support frame are arranged opposite each other at both ends of the groove. The dust removal mechanism includes a mounting base, a second exhaust element, and several guide rollers. The guide rollers are horizontally mounted between the first and second support frames to guide and support the workpiece when it moves into the dust removal mechanism. The second exhaust element... The component is set in a groove, and the mounting base is set on the side of several guide rollers away from the second exhaust element. Inside the mounting base, near one end of several guide rollers, there is a limiting seat and a first exhaust element. The limiting seat is aligned with the second exhaust element. In this invention, the air outlet of the first exhaust element faces downward and the air outlet of the second exhaust element faces upward. At the same time, there is a gap between several guide rollers. When the workpiece moves above several guide rollers, the bottom surface of the workpiece is dusted by the second exhaust element, and the top surface of the workpiece is dusted by the first exhaust element. The workpiece surface is swept by airflow in two directions, and the dust is removed under the action of airflow, thereby realizing the automatic dust removal function. Compared with the current single-sided dust removal, this invention greatly improves the work efficiency.

[0006] Furthermore, a second linear drive is provided at one end of the mounting base near the limiting seat. The working end of the second linear drive is connected to the limiting seat. The second linear drive controls the distance between the limiting seat and the guide roller. That is, when dusting the bottom surface of the workpiece, the second linear drive drives the limiting seat to move closer to the guide roller until the distance between the limiting seat and the guide roller is slightly greater than the thickness of the workpiece (the specific value is set by the operator according to the airflow size of the second exhaust element and the weight of the workpiece). The limiting seat provides vertical restriction for the workpiece, preventing it from being blown away, while ensuring that the workpiece can move smoothly on several guide rollers. The first support frame is located on the side of the conveyor belt near the turntable. A spacing adjustment component is provided at the end of the limiting seat away from the first support frame. The spacing adjustment component and the first support frame work together to limit the horizontal direction of the workpiece, preventing it from deviating, thereby improving the versatility and conveying stability of the present invention.

[0007] Furthermore, the spacing adjustment component includes several storage slots, each of which is equipped with a movable contact. A second electromagnet is provided on the side of each movable contact away from the guide roller. A magnetic block is embedded at the end of the movable contact near the second electromagnet. In this invention, the spacing between each movable contact and the first support frame is different. According to the diameter of the workpiece, the operator can activate the corresponding second electromagnet to drive the corresponding movable contact to extend out of the storage slot, thereby adjusting the limiting width of the workpiece and thus achieving adaptive guidance for workpieces of different specifications.

[0008] Furthermore, the movable contact is connected to the receiving groove via an induction spring. A piezoelectric plate is provided at the end of the movable contact near the induction spring. When the second electromagnet drives the movable contact to extend out of the receiving groove, the induction spring is compressed and acts on the piezoelectric plate. The piezoelectric plate generates a voltage signal under pressure. By monitoring this voltage signal, the operator can promptly know the extension length of the movable contact and avoid the movable contact damaging the guide roller. Finally, the present invention provides an electrostatic generating device in both the first and second exhaust elements so that the air ejected by the first and second exhaust elements carries positive and negative ions. When the airflow blows onto the workpiece surface, the positive and negative ions neutralize the static electricity on the workpiece surface, making it easier for dust to be blown away by the airflow.

[0009] Furthermore, a driving component is provided inside the second support frame. The driving component is connected to several guide rollers, and all guide rollers are driven to rotate in the same direction by the driving component, which plays an auxiliary role in conveying the workpiece.

[0010] Furthermore, the present invention arranges multiple functional modules sequentially along the workpiece's forward direction. Specifically, a flattening mechanism is provided on the side of the conveyor belt near the feeding unit, a guiding mechanism is provided on the side of the conveyor belt near the turntable, and a sorting mechanism is provided between the flattening mechanism and the dust removal mechanism. The flattening mechanism flattens the workpieces that may overlap or tilt as they fall from the feeding unit, the sorting mechanism organizes the scattered workpieces into a single column with uniform spacing, and the guiding mechanism precisely guides the cleaned workpieces to the corresponding workstations on the turntable, where they await visual inspection by the visual inspection system to take pictures and inspect them.

[0011] Furthermore, the leveling mechanism includes a fixed frame and a lifting seat. The fixed frame and the lifting seat are connected by a first linear drive component. A first leveling roller and a second leveling roller are provided on the side of the lifting seat closer to the conveyor belt, and a first rotary drive component and a second rotary drive component are provided on the side of the lifting seat away from the conveyor belt. The first rotary drive component is connected to the first leveling roller via a first coupling and a first rotating shaft, and the second rotary drive component is connected to the second leveling roller via a second coupling and a second rotating shaft. Before operation, the lifting seat is adjusted by the first linear drive component to adjust the distance between the first and second leveling rollers and the conveyor belt. During operation, the first and second rotary drive components drive the first and second leveling rollers to rotate actively to roll and level the workpieces on the conveyor belt.

[0012] Furthermore, the first leveling roller is located at the end of the lifting seat near the feeding unit, and the second leveling roller is located at the end of the lifting seat away from the feeding unit. The distance between the first leveling roller and the conveyor belt is greater than the distance between the second leveling roller and the conveyor belt. Through the above technical solution, the present invention achieves the purpose of staged leveling. On the one hand, it significantly improves the leveling quality, and on the other hand, it extends the leveling operation time, enabling the system to adapt to higher conveyor belt speeds, avoiding accumulation, and preventing some workpieces from entering the next station before being fully leveled due to insufficient processing time.

[0013] Furthermore, a first drive wheel is provided on the first rotating shaft, and a second drive wheel is provided on the second rotating shaft. A linkage assembly is provided inside the lifting seat. The linkage assembly includes a linkage shaft and two support seats. The linkage shaft is located between the two support seats. A first driven wheel and a second driven wheel are provided on the linkage shaft. A first electromagnet (fixedly connected to the linkage shaft) is provided between the first driven wheel and the second driven wheel. The first driven wheel is connected to the first drive wheel, and the second driven wheel is connected to the second drive wheel. When the leveling mechanism is working normally, the first electromagnet is in a non-working state, and the first and second driven wheels are slidably mounted on the linkage shaft. When the first or second rotary drive component fails, the first electromagnet will activate and magnetically attract the first and second driven wheels. At this time, the first and second driven wheels, together with the linkage shaft, will become a whole, thereby realizing the synchronous rotation of the first and second leveling rollers. Through the above technical solution, the first and second rotary drive components will serve as backups for each other, thereby significantly improving the fault tolerance and operational stability of the equipment.

[0014] Furthermore, a limiting element is provided inside the support base. The limiting element is connected to the first rotary drive and the second rotary drive. The limiting element can be an electronic limiting element with self-locking and automatic unlocking functions. When the leveling mechanism is working normally, the limiting element locks the linkage shaft to prevent the linkage shaft from rotating when the first and second leveling rollers rotate, thus affecting the leveling effect. When the first or second rotary drive fails, the limiting element releases the lock on the linkage shaft to allow the first or second rotary drive that is not malfunctioning to drive the first and second leveling rollers to rotate synchronously.

[0015] Compared with existing technologies, the advantages of this invention are as follows: Compared with current automatic dust removal inspection devices, this invention adopts a bidirectional air blowing structure with a first exhaust element and a second exhaust element, combined with the gap of the guide rollers to achieve simultaneous blowing of the upper and lower surfaces of the workpiece. Compared with traditional single-sided dust removal, dust removal is more thorough and efficient. In addition, to address the problem that airflow blowing may cause thin workpieces to shift, this invention is equipped with a movable limiting seat and a spacing adjustment component. Through the cooperation of the limiting seat and the spacing adjustment component, it is ensured that the workpiece is not blown away by the airflow and that the workpiece can move smoothly forward. At the same time, this invention can also accommodate different types of workpieces from thin sheets to thick blocks, significantly improving the applicability of the equipment. Finally, The invention also features a leveling mechanism with a front-high and rear-low dual working units, achieving progressive leveling and effectively preventing material stacking. This creates favorable conditions for subsequent sorting and inspection. Furthermore, the first and second rotary drive components in the leveling mechanism are connected by a linkage assembly. During normal operation, they operate independently. When either the first or second rotary drive component malfunctions, the control system activates the first electromagnet. At this time, the first or second rotary drive component that is not malfunctioning can simultaneously drive the two leveling rollers to rotate. This backup design ensures that the production line does not need to be stopped before maintenance personnel arrive, greatly improving the continuous operation capability and operational stability of the equipment.

Detailed Implementation

[0018] 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.

[0019] Example: Figures 1-9As shown, the present invention provides a technical solution: an automatic dust-removing quality inspection device, comprising a machine body 1, a feeding unit 2, a hopper 3, a discharging unit 4, and a dust removal mechanism 9. A turntable 11 is installed inside the machine body 1, and a conveyor belt 5 and a vision inspection system 12 are installed on the outer side of the turntable 11. The feed end of the conveyor belt 5 is aligned with the discharge end of the feeding unit 2. Workpieces fall smoothly from the feeding unit 2 onto the conveyor belt 5. A groove is provided on the conveyor belt 5, and a first support frame 51 and a second support frame 52 are arranged opposite each other at both ends of the groove. The dust removal mechanism 9 includes a mounting base 91, a second exhaust element 92, and several guide rollers 93. The guide rollers 93 are horizontally mounted between the first support frame 51 and the second support frame 52 to guide and support the workpiece when it moves into the dust removal mechanism 9. The second exhaust element 92 is located in the groove. Inside, the mounting base 91 is located on the side of several guide rollers 93 away from the second exhaust element 92. Inside the mounting base 91, near one end of the several guide rollers 93, there is a limiting seat 912 and a first exhaust element 913. The limiting seat 912 is aligned with the second exhaust element 92. In this invention, the air outlet of the first exhaust element 913 faces downward and the air outlet of the second exhaust element 92 faces upward. At the same time, there is a gap between the several guide rollers 93. When the workpiece moves above the several guide rollers 93, the bottom surface of the workpiece is dusted by the second exhaust element 92, and the top surface of the workpiece is dusted by the first exhaust element 913. The workpiece surface is swept by airflow in two directions, and the dust is removed under the action of airflow, thereby realizing the automatic dust removal function. Compared with the current single-sided dust removal, this invention greatly improves the work efficiency.

[0020] like Figures 4-6 As shown, a second linear drive member 911 is provided at one end of the mounting base 91 near the limiting seat 912. The working end of the second linear drive member 911 is connected to the limiting seat 912. The second linear drive member 911 controls the distance between the limiting seat 912 and the guide roller 93. That is, when dusting the bottom surface of the workpiece, the second linear drive member 911 drives the limiting seat 912 to move closer to the guide roller 93 until the distance between the limiting seat 912 and the guide roller 93 is slightly greater than the thickness of the workpiece (the specific value is determined by the operator based on the exhaust from the second exhaust element 92). The airflow size and workpiece weight are set, and the workpiece is vertically limited by the limiting seat 912 to prevent it from being blown away. At the same time, it ensures that the workpiece can move smoothly on several guide rollers 93. The first support frame 51 is set on the side of the conveyor belt 5 near the turntable 11. The end of the limiting seat 912 away from the first support frame 51 is provided with a spacing adjustment component. The workpiece is horizontally limited by the cooperation of the spacing adjustment component and the first support frame 51 to prevent it from deviating, thereby improving the versatility and conveying stability of the present invention.

[0021] like Figure 6As shown, the spacing adjustment component includes several storage slots 9121, each of which is equipped with a movable contact 9123. A second electromagnet 9122 is provided on the side of each movable contact 9123 away from the guide roller 93. A magnetic block is embedded in the end of the movable contact 9123 near the second electromagnet 9122. In this invention, the spacing between each movable contact 9123 and the first support frame 51 is different. According to the diameter of the workpiece, the operator can activate the corresponding second electromagnet 9122 to drive the corresponding movable contact 9123 to extend out of the storage slot 9121, thereby adjusting the limiting width of the workpiece and realizing adaptive guidance for workpieces of different specifications.

[0022] like Figures 4-6 As shown, the movable contact 9123 is connected to the receiving groove 9121 by an induction spring. A piezoelectric sheet is provided at the end of the movable contact 9123 near the induction spring. When the second electromagnet 9122 drives the movable contact 9123 to extend out of the receiving groove 9121, the induction spring will be squeezed and act on the piezoelectric sheet. The piezoelectric sheet generates a voltage signal under pressure. By monitoring this voltage signal, the operator can know the extension length of the movable contact 9123 in a timely manner, so as to avoid the movable contact 9123 damaging the guide roller 93. Finally, the present invention provides an electrostatic generating device in both the first exhaust element 913 and the second exhaust element 92, so that the air ejected by the first exhaust element 913 and the second exhaust element 92 carries positive and negative ions. When the airflow blows onto the surface of the workpiece, the positive and negative ions will neutralize the static electricity on the surface of the workpiece, making it easier for dust to be blown away by the airflow.

[0023] like Figures 4-6 As shown, a driving component is installed inside the second support frame 52. The driving component is connected to several guide rollers 93. The driving component drives all the guide rollers 93 to rotate in the same direction, which plays an auxiliary role in conveying the workpiece.

[0024] like Figures 2-3 As shown, the present invention has multiple functional modules arranged sequentially along the workpiece's forward direction. Specifically, a flattening mechanism 6 is provided on the side of the conveyor belt 5 near the feeding unit 2, and a guiding mechanism 8 is provided on the side of the conveyor belt 5 near the turntable 11. A sorting mechanism 7 is provided between the flattening mechanism 6 and the dust removal mechanism 9. The flattening mechanism 6 flattens the workpieces that may overlap or tilt as they fall from the feeding unit 2. The sorting mechanism 7 organizes the scattered workpieces into a single column with uniform spacing. The guiding mechanism 8 precisely guides the cleaned workpieces to the corresponding workstation on the turntable 11, where they await the visual inspection system 12 to take pictures and inspect them.

[0025] like Figures 7-8As shown, the leveling mechanism 6 includes a fixed frame 61 and a lifting seat 62. The fixed frame 61 and the lifting seat 62 are connected by a first linear drive member 63. A first leveling roller 64 and a second leveling roller 65 are provided on the side of the lifting seat 62 closest to the conveyor belt 5. A first rotary drive member 66 and a second rotary drive member 67 are provided on the side of the lifting seat 62 furthest from the conveyor belt 5. The first rotary drive member 66 is connected to the first leveling roller 64 via a first coupling 643 and a first rotating shaft 641. The second rotary drive member 67 is connected to the second leveling roller 65 via a second coupling 653 and a second rotating shaft 651. Before operation, the lifting seat 62 is adjusted by the first linear drive member 63 to adjust the distance between the first leveling roller 64 and the second leveling roller 65 and the conveyor belt 5. During operation, the first rotary drive member 66 and the second rotary drive member 67 drive the first leveling roller 64 and the second leveling roller 65 to rotate actively, so as to roll and level the workpiece on the conveyor belt 5.

[0026] like Figure 7 As shown, the first leveling roller 64 is located at the end of the lifting seat 62 near the feeding unit 2, and the second leveling roller 65 is located at the end of the lifting seat 62 away from the feeding unit 2. The distance between the first leveling roller 64 and the conveyor belt 5 is greater than the distance between the second leveling roller 65 and the conveyor belt 5. Through the above technical solution, the present invention achieves the purpose of staged leveling. On the one hand, it significantly improves the leveling quality, and on the other hand, it extends the leveling operation time, enabling the system to adapt to higher conveyor belt speeds, avoiding accumulation, and preventing some workpieces from entering the next station before being fully leveled due to insufficient processing time.

[0027] like Figures 8-9As shown, a first driving wheel 642 is mounted on a first rotating shaft 641, and a second driving wheel 652 is mounted on a second rotating shaft 651. A linkage assembly is installed inside the lifting seat 62. The linkage assembly includes a linkage shaft 621 and two support seats 6214. The linkage shaft 621 is positioned between the two support seats 6214. A first driven wheel 6211 and a second driven wheel 6212 are mounted on the linkage shaft 621. A first electromagnet 6213 (fixedly connected to the linkage shaft 621) is positioned between the first driven wheel 6211 and the second driven wheel 6212. The first driven wheel 6211 is connected to the first driving wheel 642, and the second driven wheel 6212 is connected to the second driving wheel 652. The leveling mechanism 6... During normal operation, the first electromagnet 6213 is in a non-working state, and the first driven wheel 6211 and the second driven wheel 6212 are slidably mounted on the linkage shaft 621. When the first rotary drive component 66 or the second rotary drive component 67 fails, the first electromagnet 6213 will start and magnetically attract the first driven wheel 6211 and the second driven wheel 6212. At this time, the first driven wheel 6211 and the second driven wheel 6212, together with the linkage shaft 621, will become a whole, thereby realizing the synchronous rotation of the first flattening roller 64 and the second flattening roller 65. Through the above technical solution, the first rotary drive component 66 and the second rotary drive component 67 will serve as backups for each other, thereby significantly improving the fault tolerance and operational stability of the equipment.

[0028] like Figure 9 As shown, a limiting element is provided in the support base 6214. The limiting element is connected to the first rotary drive 66 and the second rotary drive 67. The limiting element can be an electronic limiting element with self-locking and automatic unlocking functions. When the leveling mechanism 6 is working normally, the limiting element locks the linkage shaft 621 to prevent the linkage shaft 621 from rotating when the first leveling roller 64 and the second leveling roller 65 rotate, thereby affecting the leveling effect. When the first rotary drive 66 or the second rotary drive 67 fails, the limiting element releases the lock of the linkage shaft 621 to facilitate the first rotary drive 66 or the second rotary drive 67, which has not failed, to drive the first leveling roller 64 and the second leveling roller 65 to rotate synchronously.

[0029] The working principle of this invention is as follows: During operation, the workpiece is smoothly dropped into the conveyor belt 5 by the feeding unit 2. Then, the workpiece first passes through the flattening mechanism 6. The first flattening roller 64 and the second flattening roller 65 in the flattening mechanism 6 flatten the overlapping or inclined workpieces on the conveyor belt 5. After the workpiece is flattened, it moves to the side of the sorting mechanism 7. The sorting mechanism 7 organizes the scattered workpieces into a single row with uniform spacing. Then, the workpiece moves on several guide rollers 93. The bottom surface of the workpiece is dusted by the second exhaust element 92, and the top surface of the workpiece is dusted by the first exhaust element 913. The workpiece surface is swept by airflow in two directions. The dust is removed under the action of airflow, thereby realizing the automatic dust removal function. After the dust removal is completed, the cleaned workpiece is accurately guided to the corresponding station on the turntable 11 by the guiding mechanism 8. Finally, the workpiece is moved to the working position of the vision inspection system 12 by the turntable 11. The vision inspection system 12 takes pictures of the workpiece for inspection. After the workpiece inspection is completed, the inspected workpiece is transported to the hopper 3 by the unloading unit 4.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
