Description

Technical Field

[0001] This utility model relates to the field of visual inspection, and in particular to a material feeding workstation for visual inspection. Background Technology

[0002] Industrial vision inspection acquires stable, high-quality images using industrial-grade hardware (such as cameras, light sources, and lenses). After preprocessing to eliminate interference and enhance features, key parameters are extracted through dimensional measurement, defect identification, and assembly verification algorithms. Finally, the images are compared with standards to determine their conformity and are linked to the production line to perform sorting or alarm operations. Data is also recorded for traceability. This is the mainstream technology direction in current industrial inspection.

[0003] Existing visual inspection loading methods mostly employ a sequential process of picking, positioning, conveying, and inspection to load workpieces. Specifically, during picking, a robotic arm uses a clamp or vacuum suction cup to grab a single part from a tray or hopper according to a preset path. The robotic arm then conveys the part to the inspection station, precisely placing it on the inspection table. Finally, the visual inspection equipment performs the inspection operation on the workpiece. However, in this loading method, loading, inspection, and unloading must be completed sequentially at the same station. The next material cannot enter the inspection stage until the entire process of the previous material is completed, directly limiting the overall efficiency of the production line. To solve the above problems, this application provides a visual inspection loading workstation. Utility Model Content

[0004] To address the aforementioned issues, this application provides a material loading workstation for visual inspection.

[0005] To achieve the above objectives, this application provides the following technical solution: a loading workstation for visual inspection, comprising a circular tray and a base fixed below the tray. A visual detector is connected to the center of the tray via an inclined arm, and a rotatable linkage bracket is provided on the tray. The linkage bracket has a ring structure, and multiple supports are fixed on the linkage bracket and arranged equidistantly along a circumferential trajectory. Each support is provided with a first feeding plate and a second feeding plate for placing workpieces. The first feeding plate and the second feeding plate can move synchronously toward the distribution direction of the supports. As the linkage bracket rotates, the multiple supports rotate sequentially to below the visual detector. When the first feeding plate and the second feeding plate move synchronously, the workpieces located inside the first feeding plate and the second feeding plate are sequentially subjected to visual inspection operations.

[0006] Furthermore, a guide toothed ring is fixed to the outside of the linkage bracket and is coaxially distributed therewith. An electric gear one that meshes with the guide toothed ring is installed on the tray. When the electric gear one rotates, the guide toothed ring, the linkage bracket and multiple brackets rotate synchronously.

[0007] Furthermore, an annular guide rail is fixed on the tray, and the linkage bracket is rotatably mounted to the annular guide rail.

[0008] Furthermore, each of the support bases is detachably mounted with a parallel material platform. The first and second material feeding plates are both located above the material platform. As the linkage bracket and multiple support bases rotate synchronously, the multiple material platforms rotate sequentially to below the vision detector.

[0009] Furthermore, the bottom ends of the first and second feeding plates are connected by a connecting frame. Each of the multiple connecting frames has a drive rack fixed on one side, which is distributed along a straight path. Each of the feeding platforms is equipped with an electric gear two that meshes with the drive rack. When the electric gear two rotates, the drive rack, the connecting frame, the first feeding plate, and the second feeding plate move synchronously.

[0010] Furthermore, a guide rail is fixed on the material platform, and the connecting frame is slidably connected to the guide rail. When the connecting frame moves, the first feeding plate and the second feeding plate move along the distribution direction of the guide rail.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] This invention allows the vision detector to continuously perform visual inspection operations on workpieces inside multiple sets of first and second feeding plates. The visual inspection operation and the workpiece replacement operation inside each set of first and second feeding plates can be performed simultaneously, reducing the time spent on material replacement after a single inspection and improving the efficiency of the visual inspection operation. Furthermore, this invention, through a dual-station moving mode, can quickly perform visual inspection operations on two parts, further saving time and improving the efficiency of visual inspection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Reference Figure 1-4 The illustrated visual inspection loading workstation includes a circular tray 1 and a base 2 fixed below the tray 1. A visual detector 11 is connected to the center of the tray 1 via an inclined arm. The visual detector 11 is linked to a PLC system via an encoder. When the object being inspected reaches a designated position, the PLC system sends a trigger signal to the camera in the visual detector 11 to ensure that the camera takes a picture when the object is stationary.

[0021] In this invention, a rotatable linkage bracket 4 is provided on the tray 1. The linkage bracket 4 has a ring structure, and multiple support plates 5 are fixed on the linkage bracket 4 and arranged equidistantly along a circumferential trajectory. Each support plate 5 has a first feeding plate 61 and a second feeding plate 62 above it for placing workpieces. The first feeding plate 61 and the second feeding plate 62 can move synchronously toward the distribution direction of the support plates 5. As the linkage bracket 4 rotates, the multiple support plates 5 rotate sequentially to below the vision detector 11, allowing the vision detector 11 to successively perform visual inspection operations on the workpieces inside the first feeding plate 61 and the second feeding plate 62 above the multiple support plates 5.

[0022] When the vision detector 11 performs vision inspection operation above the same support 5, after the workpiece inside the first feeding plate 61 is inspected, the first feeding plate 61 and the second feeding plate 62 move synchronously, so as to achieve the purpose of allowing the workpieces inside the first feeding plate 61 and the second feeding plate 62 located above the same support 5 to be subjected to vision inspection operation in sequence.

[0023] After the workpieces inside the first feeding plate 61 and the second feeding plate 62 located on the same support 5 are visually inspected, with the rotation of the linkage bracket 4, the support 5 carrying the first feeding plate 61, the second feeding plate 62 and the inspected workpieces can rotate away from the vision detector 11. The operator can then perform a material replacement operation on the workpieces inside the first feeding plate 61 and the second feeding plate 62, and add the workpieces to be inspected. The workpieces to be inspected can be moved back under the vision detector 11 with the rotation of the linkage bracket 4, the support 5, the first feeding plate 61 and the second feeding plate 62 for visual inspection.

[0024] During this process, as the linkage bracket 4 rotates continuously, multiple support blocks 5 can rotate sequentially to below the vision detector 11. This allows the vision detector 11 to perform continuous visual inspection operations on the workpieces inside multiple sets of first feeding plates 61 and second feeding plates 62. The visual inspection operation and the replacement operation of the workpieces inside each set of first feeding plates 61 and second feeding plates 62 after the inspection can be carried out simultaneously. Therefore, the normal implementation of the visual inspection operation is not affected during the material replacement process, reducing the time spent on material replacement operations after a single inspection and improving the efficiency of the visual inspection operation.

[0025] Furthermore, during the material change operation of the workpieces inside the same set of first feeding plates 61 and second feeding plates 62, as the first feeding plates 61 and second feeding plates 62 move, a dual-station movement mode is formed, which can quickly perform visual inspection operations on two parts. Compared with the mode of gradually inspecting and changing a single workpiece, it saves time and improves the efficiency of visual inspection.

[0026] like Figure 2 , Figure 3 As shown, a guide toothed ring 3 is fixed to the outside of the linkage bracket 4 and is coaxially distributed therewith. An electric gear 31 that meshes with the guide toothed ring 3 is installed on the tray 1. The electric gear 31 is controlled by the PLC system. When the electric gear 31 rotates, the guide toothed ring 3, the linkage bracket 4 and multiple support blocks 5 rotate synchronously to drive multiple sets of first feeding plates 61 and second feeding plates 62 to rotate successively.

[0027] Furthermore, in order to maintain the continuity of rotation of the linkage bracket 4 and the guide gear ring 3, such as Figure 3 As shown, the present invention has an annular guide rail 12 fixed on the tray 1, and the linkage bracket 4 is rotatably installed with the annular guide rail 12.

[0028] like Figure 4As shown, each support 5 has a detachable, parallel material platform 6 mounted on top of it, with the first feeding plate 61 and the second feeding plate 62 located above the material platform 6. Therefore, with the synchronous rotation of the linkage bracket 4 and the multiple supports 5, the multiple material platforms 6 can be rotated sequentially to below the vision detector 11. Since the material platform 6 is a detachable structure, it is convenient for workers to disassemble the material platform 6 to perform maintenance and replacement operations on the first feeding plate 61 and the second feeding plate 62.

[0029] like Figure 4 As shown, the bottom ends of the first feeding plate 61 and the second feeding plate 62 are connected by a connecting frame 63. Each of the multiple connecting frames 63 has a drive rack 631 fixed on one side, distributed along a straight path. Each material platform 6 is equipped with an electric gear 632 that meshes with the drive rack 631. The electric gear 632 is controlled by a PLC system. When the electric gear 632 rotates, the drive rack 631, the connecting frame 63, the first feeding plate 61, and the second feeding plate 62 move synchronously. This achieves the purpose of moving the workpiece inside the first feeding plate 61 away from the vision detector 11 after visual inspection, and moving the workpiece inside the second feeding plate 62 below the vision detector 11 to undergo visual inspection.

[0030] To maintain the stability of the connecting frame 63 during its movement, such as Figure 4 As shown, the material platform 6 of this utility model is fixed with a guide rail 64, and the connecting frame 63 is slidably connected to the guide rail 64. When the connecting frame 63 moves, the first feeding plate 61 and the second feeding plate 62 move along the distribution direction of the guide rail 64.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
