[0002] Spot welding is commonly used in industries such as automotive, home appliances, and electronic equipment. Nuts, as connecting parts, require precise spot welding during manufacturing to ensure their strength and stability. Nut spot weld inspection is a quality inspection performed when nuts are connected to other metal parts using the spot welding process during manufacturing. This inspection removes defective products to ensure a high product pass rate.

[0003] Visual inspection is a common method that uses a vision camera in conjunction with an image processing system to examine defects, quality problems, or other features on the surface or structure of an object. Applied to the inspection of welded nuts, it primarily detects the weld morphology, location, and surface contaminants. Compared to manual inspection, it improves accuracy and efficiency while saving labor costs.

[0004] Because of the variety of workpiece types, specific tools are required to fix specific products during inspection, which makes workpiece positioning difficult. Inaccurate positioning often prevents the product from being accurately placed in the inspection area of ​​the vision inspection agency, resulting in unsatisfactory inspection results.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0025] like Figures 1-5 As shown, this utility model provides a nut spot welding inspection device, including a mounting platform 1, a vision inspection component and a universal base 4 disposed on the mounting platform 1, and a replaceable fixed template 5 disposed on the universal base 4. The vision inspection component includes a vision bracket 2 and a camera module mounted on the vision bracket 2, the camera module being located above the fixed template 5. The fixed template 5 is placed on the universal base 4 and snapped into place therewith. A limiting component is provided on the fixed template 5, and the limiting component is detachably connected to the universal base.

[0026] In the above scheme, the fixed template 5 is used to place and position the workpiece 19 to be inspected. Because the shape of the workpiece 19 is different, the fixed template 5 is replaceable, such as... Figure 3 As shown, two types of fixed templates 5 are displayed, corresponding to two types of workpieces 19. The bottom structure of the fixed template 5 remains unchanged. Only the positioning parts on it can be adjusted according to the shape of the workpiece 19 to ensure that the workpiece 19 is placed stably. After placement, the nut on it can be located below the camera module.

[0027] The camera module described in this solution includes several visual cameras 3 spaced apart, all of which face the fixed template 5. For example... Figure 1The embodiment uses six vision cameras 3 to capture images, and the processing module performs image processing to achieve defect detection. It is worth noting that the above image processing is a conventional method in existing technology. A screen bracket 17 is also provided on the mounting platform 1, and a display screen 18 for displaying the detection structure is mounted on the screen bracket. After detection, the detection results are displayed on the display screen 18, showing whether the nut welding on the workpiece 19 is qualified, whether there are contaminants, and whether the weld point position is offset, etc.

[0028] The mounting platform 1 is provided with two limiting guide rails 6, and the bottom of the universal base 4 is provided with a limiting slider 7 connected to the limiting guide rails 6. The universal base 4 can realize the installation of different fixing templates 5. When it is necessary to replace the fixing template 5, the universal base 4 can be pulled out by the push-pull handle 10 provided on the universal base 4, and then the fixing template 5 can be removed and replaced.

[0029] To ensure the accurate movement of the universal base 4, a first limiting block 8 and a second limiting block 9 are provided on the mounting platform 1 along the direction of movement of the universal base 4. The universal base 4 is located between the first limiting block 8 and the second limiting block 9. The setting of the first limiting block 8 and the second limiting block 9 can ensure that the universal base 4 moves accurately below the camera module, thereby ensuring that the workpiece 19 is located within the shooting area of ​​the camera module.

[0030] like Figures 4-5 As shown, the bottom of the fixed template 5 is provided with a plug-in block 11, and the universal base 4 is provided with a plug-in groove 12 corresponding to the plug-in block 11. The limiting component includes a movable rod 13 slidably connected to the plug-in block 11, a pressing plate 14 connected to the movable rod 13, and a spring structure 15 connected to the pressing plate. Two sets of movable rods 13 and pressing plates 14 are symmetrically arranged, and the spring structure 15 is located between the two pressing plates 14. A plug hole 16 is provided in the plug-in groove 12. In the natural state, the movable rod 13 extends out of the plug-in block 11 and is inserted into the plug hole 16.

[0031] In the above scheme, when the fixed template 5 is installed with the universal base 4, the plug-in block 11 on the fixed template 5 is inserted into the slot on the universal base 4, which achieves the initial positioning of the fixed template 5. Then, the pressing plate 14 is released. At this time, the spring pushes the two pressing plates 14 to move away from each other as it returns to its original length. This causes the two movable rods 13 to be inserted into the insertion holes 16 on both sides of the plug-in slot 12, thereby limiting the fixed template 5 and ensuring that the fixed template 5 will not fall off the universal base 4 due to accidental conditions. At the same time, when the fixed template 5 is replaced, the movable rod 13 can be removed from the insertion hole 16 to remove the fixed template 5. The operation is convenient and the replacement efficiency is high.

[0032] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
