Description

Technical Field

[0001] This utility model relates to the field of die-casting product testing technology, and in particular to a device for detecting surface defects in die-casting products. Background Technology

[0002] Die-cast products include die-cast parts made of various materials such as aluminum alloy, zinc alloy, and magnesium alloy. During the production process, due to various reasons, defects such as cracks, porosity, and inclusions may appear on the surface of these die-cast products. Therefore, it is necessary to inspect the surface defects of the die-cast products after production.

[0003] Chinese patent publication number CN223037824U discloses a "Surface Defect Detection Equipment for Aluminum Die Casting Production". The device first places several sets of plate-shaped aluminum die castings into several sets of transparent shell plates. Then, it activates a cylinder on the lower side of a fixed frame plate to retract a telescopic rod. This, in conjunction with two sets of limiting rods and two sets of limiting clamps, moves a lifting plate downwards, which in turn moves the upper detection camera downwards. Next, it activates a drive motor on a support base to rotate a rotating shaft. This, in conjunction with a limiting ring plate and a limiting rail, rotates a movable carrier plate. Finally, with the cooperation of a metal rod and a magnetic plate, the transparent shell plate is positioned between the lower and upper detection cameras. This enables batch inspection of several sets of aluminum die castings and allows simultaneous inspection of the upper and lower surfaces of the plate-shaped aluminum die castings, significantly improving inspection efficiency.

[0004] However, the aforementioned patent can only perform surface defect detection on a group of die-cast products at the same time, resulting in low efficiency in surface defect detection of die-cast products. Therefore, we propose a surface defect detection device for die-cast products to solve the aforementioned problems. Utility Model Content

This allows the first and second vision cameras to simultaneously detect surface defects in two sets of die-cast products, improving detection efficiency and saving labor costs. Furthermore, by incorporating a second hydraulic rod, the distance between the first and second vision cameras can be adjusted, making it suitable for die-cast products of different sizes and expanding the device's applicability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0019] Reference Figures 1-3 As shown, a surface defect detection device for die-cast products includes a workbench 1. A frame 2 is installed on the lower end surface of the workbench 1. A set of rotatable rotating disks 3 are installed on both sides above the upper end surface of the workbench 1. Multiple sets of perforations 4 are equally spaced on both sets of rotating disks 3. A set of transparent plates 5 is installed on the inner wall of each set of perforations 4. Rotating components for driving the two sets of rotating disks 3 to rotate are installed on the two sets of rotating disks 3. The rotating components include two sets of rotating rods 6. The two sets of rotating rods 6 are respectively installed on the lower end surface of the two sets of rotating disks 3. The lower ends of the two sets of rotating rods 6 are rotatably connected to both sides of the upper end surface of the workbench 1.

[0020] A first pulley 7 is fitted on the outer wall of a set of rotating rods 6. A connecting belt 8 is fitted on the outer side of the first pulley 7. A second pulley 9 is installed inside the other end of the connecting belt 8. The second pulley 9 is fitted on the outer wall of another set of rotating rods 6. The lower end of a set of rotating rods 6 is connected to the output end of a rotary motor 10. The rotary motor 10 is installed on the upper surface of the workbench 1. A tension wheel 11 is installed on one side of the connecting belt 8. A mounting block 12 is rotatably installed on the lower end face of the tension wheel 11. A first hydraulic rod 13 is installed on one side of the mounting block 12. The other end of the first hydraulic rod 13 is installed on the upper surface of a fixing block 14. The fixing block 14 is installed on one side wall of the workbench 1. Each of the two sets of rotating rods 6 has a set of support blocks 15 on one side. The lower end of each set of support blocks 15 is connected to the upper end of the worktable 1. Each of the two sets of support blocks 15 has a set of support plates 16 on the upper end of the two sets of support plates 16. Each of the two sets of support plates 16 has a set of first vision cameras 17 on the upper end of the two sets of first vision cameras 17. Each of the two sets of first vision cameras 17 has a set of second vision cameras 18 above it.

[0021] In this embodiment, the rotary motor 10 is started, which drives a set of rotating rods 6 to rotate. The rotating rods 6 drive the second pulley 9 to rotate, and the second pulley 9 drives the first pulley 7 to rotate via the connecting belt 8. The first pulley 7 drives another set of rotating rods 6 to rotate, so that the two sets of rotating disks 3 rotate synchronously. This allows the second vision camera 18 and the first vision camera 17 to sequentially perform surface defect detection on multiple sets of die-cast products, improving the efficiency of die-cast product inspection. By setting up the rotating component, the two sets of rotating disks 3 can be driven to rotate, thereby driving multiple sets of die-cast products to rotate. This allows the first vision camera 17 and the second vision camera 18 to simultaneously perform surface defect detection on two sets of die-cast products, improving inspection efficiency and saving labor costs.

[0022] Furthermore, each of the two sets of support plates 16 has a through groove 19 on its side wall, and each of the two sets of through grooves 19 has a sliding rod 20 on its inner wall. Each of the two sets of sliding rods 20 has a sliding sleeve 21 slidably fitted on its outer wall, and each of the two sets of sliding sleeves 21 has a lifting block 22 on one side wall. The two sets of second vision cameras 18 are respectively mounted on the lower end face of the two sets of lifting blocks 22. Each of the two sets of support plates 16 has a positioning block 23 mounted on one side wall, and each of the two sets of positioning blocks 23 has a second hydraulic rod 24 mounted on its upper end face. Each of the two sets of second hydraulic rods 24 has a moving block 25 mounted on its upper end face, and the two sets of moving blocks 25 are respectively connected to the two sets of sliding sleeves 21. Two sets of second hydraulic rods 24 are activated, which drive two sets of moving blocks 25 downwards. The moving blocks 25 drive two sets of sliding sleeves 21 downwards, which in turn drive two sets of lifting blocks 22 downwards. The lifting blocks 22 then drive two sets of second vision cameras 18 downwards, allowing the second vision cameras 18 and the first vision camera 17 to simultaneously inspect the upper and lower surfaces of the die-cast product. By setting the second hydraulic rods 24, the distance between the first vision camera 17 and the second vision camera 18 can be adjusted, thus making it suitable for die-cast products of different sizes and improving the applicability of the device. Example

[0023] Reference Figures 1-2 As shown, a slide rail 26 is provided on the upper surface of the workbench 1, and a slider 27 is slidably arranged on the inner wall of the slide rail 26. The upper surface of the slider 27 is connected to the lower surface of the mounting block 12. By setting the slide rail 26 and the slider 27, the mounting block 12 can be limited, thereby improving the stability of the movement of the mounting block 12.
