Description

Technical Field

[0001] This utility model belongs to the technical field of visual inspection automation equipment, and in particular relates to a vertical inspection equipment for plate-shaped parts. Background Technology

[0002] With the rapid development of industrial automation technology, automated vision inspection equipment has become an indispensable tool in industrial manufacturing. Traditional manual inspection methods have many drawbacks in industrial parts production and quality inspection, such as being time-consuming, prone to errors due to fatigue, and easily missing minor defects and flaws, failing to meet the efficiency and quality requirements of modern industrial production. Therefore, automated vision inspection equipment has emerged. By simulating human visual function, it uses high-precision industrial cameras to capture product images and performs rapid and accurate analysis and processing through advanced image processing algorithms and deep learning technology, solving a series of problems in various stages of industrial parts production and quality inspection.

[0003] Chinese patent document CN213715090U discloses a PCB component inspection system. A detection box is screwed onto the top center of a bottom fixing plate. An inspection camera and an inspection lamp are installed inside the inspection box. A fixed support plate is welded to the top of the bottom fixing plate, with a transmission gear connected to one end of the support plate and a transmission chain connected to the other end. A fixed protective plate is rotatably connected to a transmission rod. L-shaped support plates are symmetrically welded at equal intervals to one end of the transmission chain. The inspection lamp and camera illuminate and photograph the PCB board for inspection, facilitating solder joint detection. The transmission chain and L-shaped support plates fix and move the PCB board, allowing it to be transported to the required position during inspection. This enables rapid inspection without manual placement, avoiding missed detections due to tilting and ensuring efficient and effective testing.

[0004] In the aforementioned patented solutions, when the PCB board is transported horizontally, the conveying device must support the edges of the PCB board. This results in the supported area not being fully imaged and detected by the inspection camera, creating a blind spot. Conversely, transporting the PCB board by supporting its side / narrow edge when it is tilted is inconvenient for automated feeding and also makes it difficult to accommodate PCB boards of different sizes and shapes. Utility Model Content

[0005] To overcome the technical problems in existing technologies where parallel-placed plate-shaped parts create blind spots that cannot be captured by the inspection camera, and where tilted-placed plate-shaped parts are inconvenient for automatic feeding and incompatible with plate-shaped parts of different sizes and shapes, this utility model aims to provide a vertical inspection device for plate-shaped parts. This device uses two adjustable clamping plates on a straight feeding module to hold a mounting strip with suction cups. The suction cups can be adjusted in multiple directions, allowing them to move various plate-shaped parts from the feeding pusher to the supporting strip. The sides of the plate-shaped parts are supported during transport, eliminating blind spots in visual inspection.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a vertical inspection device for plate-shaped parts, comprising a structural inclined plate, which is inclinedly disposed on a structural frame; a support strip, which is horizontally disposed on the lower front side of the structural inclined plate and is used to support the side of the plate-shaped parts; a pusher, which is disposed on the structural inclined plate and is used to push the plate-shaped parts to slide along the upper end of the support strip; a vision module, which is disposed in the middle of the support strip; and an inclined support plate, which is inclined...

[0010] Specifically, pressure plates are provided at both ends of the positioning plate; the two pressure plates abut against the first clamping plate and the second clamping plate respectively.

[0011] By sliding / rotating the positioning plate along the T-slot to adjust the spacing of the mounting strips, and then adjusting the height of the mounting strips, the arrangement of the suction cups can accommodate plate-shaped parts of different sizes, shapes, and thicknesses. The pressure plate ensures that the clamping force of the first and second clamping plates is evenly distributed on the mounting strips, making the fixing effect of the mounting strips more stable and ensuring the synchronicity of the movement of multiple suction cups.

[0012] Furthermore, a first conveyor belt is horizontally arranged at the end of the support strip away from the inclined plate; a roller is horizontally slidably connected to the back of the structural inclined plate; the roller is directly opposite the first conveyor belt; the rotation axis of the roller is parallel to the length direction of the support strip; the roller is used to push the plate-shaped components on the first conveyor belt onto the first conveyor belt.

[0014] The baffle can prevent the plate-shaped components on the support strip from moving excessively, and prevent damage to the plate-shaped components due to malfunction or accident during the movement of the U-shaped frame.

[0015] Specifically, a lifting platform is provided at the end of the support bar away from the inclined support plate; a second conveyor belt is provided on the lifting platform; and the first conveyor belt is located between the second conveyor belt and the support bar.

[0019] Furthermore, an outer shell is provided on the outside of the structural frame; a display screen is provided on the front of the outer shell; and a keyboard tray is rotatably connected to the front of the outer shell below the display screen.

[0020] Compared to existing technologies, the advantages of this invention are as follows: This invention eliminates blind spots in the visual inspection process by supporting the sides of inclined plate-shaped components, and is compatible with plate-shaped components of different sizes and specifications.

[0046] Working process: A stack of plate-shaped components (such as PCB boards) is placed on the feeding push plate 32. The material distribution linear module 41 drives the suction cup 42 to extend outward until it abuts against the topmost plate-shaped component. After the suction cup 42 adsorbs the plate-shaped component, the material distribution linear module 41 drives the suction cup 42 back to its original position. The plate-shaped component is attached to the structural inclined plate 2, and its lower side abuts against the upper end of the support strip 21. The feeding motor 33 drives the feeding push plate 32 to move upward a distance equal to the thickness of one plate-shaped component.

[0047] The transverse cylinder 63 drives the pusher block 641 to extend out of the structural inclined plate 2. The feeding linear module 61 drives the pusher block 641 to slide horizontally, causing the pusher block 641 to push the plate-shaped component to slide. The plate-shaped component completes the visual inspection process as it passes through the vision module 5. Subsequently, the plate-shaped component is pushed to the far right, directly opposite the roller 73. The transverse cylinder 63 drives the pusher block 641 to retract to the back of the structural inclined plate 2, and returns to its original position under the drive of the feeding linear module 61.

[0048] The discharge cylinder 71 drives the roller 73 to extend, pushing the plate-shaped parts on the support strip 21 onto the first conveyor belt 8. Under the conveying of the first conveyor belt 8, the plate-shaped parts move onto the second conveyor belt 92. After the plate-shaped parts enter the second conveyor belt 92, the lifting platform 91 slides down a distance equal to the thickness of one plate-shaped part. This process is repeated, and the plate-shaped parts on the second conveyor belt 92 gradually stack together.

[0049] Adjustment process: Based on the different sizes and shapes of the plate-shaped parts, the clamping cylinder 44 is extended. First, the spacing and position of the positioning plates 47 are adjusted, i.e., the suction cup 42 is adjusted horizontally. Then, the height of each mounting strip 45 is adjusted, and the suction cup 42 is adjusted vertically. Finally, the clamping cylinder 44 is retracted, causing the first clamping plate 43 and the second clamping plate 46 to clamp the pressure plate, thereby clamping the mounting strip 45.
