Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a floating pressure roller automatic plate feeding and photographing mechanism. Background Technology

[0002] In industries such as electronics manufacturing, metal processing, and printing and packaging, the automated production process for sheet metal products (such as PCB circuit boards and thin metal sheets) encompasses multiple stages, including material feeding, processing, and quality inspection. Among these, board feeding and visual inspection are crucial steps in ensuring product quality and production efficiency: Production efficiency requirements: Traditional manual board feeding and visual inspection are insufficient to meet the demands of large-scale, high-speed production, necessitating automated equipment for continuous and efficient operation; Quality control upgrades: As products become more refined and complex, high-precision visual inspection is needed to replace manual sampling, reducing the defect rate.

[0003] Traditional board feeding and imaging mechanisms have the following limitations: Unstable board feeding: When conveying boards of different thicknesses and surface properties, the fixed pressure rollers are prone to slippage, deviation, or indentation, affecting the accuracy of subsequent imaging; Poor adaptability: It is impossible to quickly switch the conveying parameters of different specifications of boards, resulting in long changeover and adjustment times and restricting flexible production capabilities; Imaging issues: Positioning deviation leads to image distortion: Positioning deviation during board feeding causes the imaging area to deviate from the preset range, affecting the accuracy of detection; Insufficient lighting and angle control: The fixed settings of the light source and camera in traditional mechanisms are difficult to adapt to the reflective characteristics of different board materials, easily producing shadows or reflective interference.

[0023] In this embodiment, the frame 1 includes a fixed base plate 27, multiple support columns 28, and a support plate 29. The frame 1 provides installation conditions for the adjustment mechanism and the plate feeding mechanism. The adjustment mechanism can control the position adjustment of the camera body 30, and the camera body 30 can take pictures of the plate. When it is necessary to take pictures of the plate, the plate is placed at the inlet, and the drive assembly is activated. The drive assembly drives the transmission assembly one to rotate, and the transmission assembly one drives the lower roller assembly and the transmission assembly two to rotate. The transmission assembly two drives the upper roller assembly to rotate. At this time, the upper roller assembly, in conjunction with the lower roller assembly, transports the plate to below the camera and then stops working. At the same time, the light source assembly works to provide supplementary lighting for the camera. After the camera body 30 takes pictures of the plate, the plate is sent out, thereby solving the problem of unstable conveying affecting the imaging accuracy of the existing plate feeding and imaging mechanism.

[0024] Furthermore, the drive assembly includes a connecting plate 3, a motor 4, and a main sprocket 5. The connecting plate 3 is fixedly connected to the frame 1 and located on one side of the frame 1. The motor 4 is fixedly connected to the connecting plate 3 and located on the connecting plate 3. The main sprocket 5 is fixedly connected to the output end of the motor 4.

[0025] In this embodiment, the connecting plate 3 provides the installation conditions for the motor 4, and the operation of the motor 4 can drive the main sprocket 5 to rotate.

[0026] Furthermore, the transmission assembly includes a sprocket 6 and a chain 7. The sprocket 6 is rotatably connected to the frame 1 and is located on the frame 1. The chain 7 is sleeved on the sprocket 6 and the main sprocket 5.

[0027] In this embodiment, the rotation of the main sprocket 5, in conjunction with the chain 7, drives the sprocket 6 to rotate. The rotation of the sprocket 6 can drive the main gear 10 to rotate, and at the same time, it can cooperate with the chain 15 to drive the sprocket 14 to rotate.

[0028] Furthermore, the lower roller assembly includes a main gear 10, multiple transmission gears 11, multiple driven gears 12, and multiple lower rollers 13. The main gear 10 is fixedly connected to the sprocket 6 and meshes with the adjacent transmission gear 11. The multiple transmission gears 11 are rotatably connected to the frame 1 and are all located on the frame 1. The multiple driven gears 12 are rotatably connected to the frame 1 and mesh with the adjacent transmission gears 11. The multiple lower rollers 13 are fixedly connected to the multiple driven gears 12 and rotatably connected to the frame 1.

[0029] In this embodiment, the rotation of the main gear 10 can drive the adjacent transmission gear 11 to rotate.

[0030] Furthermore, the transmission assembly two includes multiple guide shafts 8, two elastic pin plates 9, a second sprocket 14, a second chain 15, a third sprocket 16, and a third chain 17. The multiple guide shafts 8 are all mounted on the frame 1. The two elastic pin plates 9 are respectively mounted on the multiple guide shafts 8.

The third chain 17 is sleeved on the third sprocket 16 and the second sprocket 14.

[0031] In this embodiment, the multiple guide shafts 8 provide installation conditions for the two elastic pin plates 9. When the plate enters between the upper roller 21 and the lower roller 13, the two elastic pin plates 9 move upward along the guide shafts 8, thereby driving the multiple upper rollers 21 to move upward. When conveying different plates, the upper rollers 21 are floated and adjusted, and the downward pressure is automatically adjusted according to the plate thickness to ensure stable conveying while avoiding damage to the plate surface. The second chain 15, in conjunction with the first sprocket 6, can drive the second sprocket 14 to rotate. The rotation of the second sprocket 14 can drive the second main gear 18 to rotate. At the same time, it can also work with the third chain 17 to drive the third sprocket 16 to rotate. The rotation of the third sprocket 16 can drive the support roller 25 to rotate.

[0032] Furthermore, the upper roller assembly includes a main gear 18, multiple transmission gears 19, multiple driven gears 20, and multiple upper rollers 21.

The multiple upper rollers 21 are rotatably connected to the elastic pin plate 9 and fixedly connected to the multiple driven gears 20.

[0033] In this embodiment, the rotation of the main gear 18 can drive the two adjacent driven gears 20 to rotate. The two driven gears 20, together with the multiple transmission gears 19, drive the driven gears 20 to rotate. In turn, the multiple driven gears 20 drive the multiple upper rollers 21 to rotate counterclockwise, thereby realizing the conveying of the plate.

[0034] Furthermore, the light source assembly includes two fixing plates 22, two cylinders 31, a mounting plate 32, and a line scan light source 23. The two fixing plates 22 are respectively fixedly connected to the frame 1 and are both located on the frame 1. The two cylinders 31 are respectively fixedly connected to the two fixing plates 22 and are respectively located on the two fixing plates 22. The mounting plate 32 is fixedly connected to the output ends of the two cylinders 31. The line scan light source 23 is mounted on the mounting plate 32.

[0035] In this embodiment, the two fixing plates 22 provide installation conditions for the two cylinders 31. The operation of the two cylinders 31 can drive the line scan light source 23 on the mounting plate 32 to move. The mounting plate 32 provides installation conditions for the line scan light source 23. The line scan light source 23 can provide supplementary lighting for the board and prevent shadows or reflection interference.

[0036] Furthermore, the feeding mechanism also includes a feed roller 24 and a support roller 25. The feed roller 24 is mounted on the frame 1, and the support roller 25 is fixedly connected to the sprocket 16 and rotatably connected to the frame 1.
