[0020] 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.

[0021] Please see Figures 1 to 3 The online detection device for coating defects of automotive parts in this embodiment includes a base 1, a bracket 2 fixedly connected to the top of the base 1, and a detection camera 3 fixedly connected to the inner top wall of the bracket 2. The top of the base 1 is provided with an adjustment component for adjusting the position of the part to be inspected.

[0022] Please see Figure 1 In this embodiment, the adjustment component includes a first frame 4 fixedly connected to the top of the base 1. A first motor 5 is fixedly connected to the right side of the first frame 4. A first threaded rod 6 is fixedly connected to the output shaft of the first motor 5. A first threaded block 7 is threadedly connected to the outer side of the first threaded rod 6. A slider 8 is fixedly connected to the top of the first threaded block 7. A fixing plate 9 is fixedly connected to the top of the slider 8. A second frame 10 is fixedly connected to both the left and right sides of the top of the fixing plate 9. A second motor 11 is fixedly connected to the front of the left second frame 10. A second threaded rod 12 is fixedly connected to the output shaft of the second motor 11. A second threaded block 13 is threadedly connected to the outer side of the second threaded rod 12. A guide rod 14 is fixedly connected between the inner front and rear side walls of the right second frame 10. A guide block 15 is slidably connected to the outer side of the guide rod 14. A connecting block 16 is fixedly connected to the opposite side of the second threaded block 13 and the guide block 15. A placement component for placing the component to be tested is provided between the opposite sides of the left and right connecting blocks 16.

[0023] Specifically, the placement component includes a fixing block 17 fixedly connected between opposite sides of the left and right connecting blocks 16. A mounting plate 18 is fixedly connected to the top of the fixing block 17. A first electric push rod 19 is fixedly connected to the top of the mounting plate 18. A placement plate 20 is fixedly connected to one end of the movable rod of the first electric push rod 19. A second electric push rod 21 is fixedly connected to both the left and right sides of the top of the placement plate 20. A clamping plate 22 is fixedly connected to one end of the movable rod of the second electric push rod 21.

[0024] Specifically, rubber pads are fixedly connected to opposite sides of the left and right clamping plates 22, and the size of the rubber pads is equal to the size of the clamping plates 22.

[0025] It should be noted that the high coefficient of friction of the rubber pad effectively increases the friction with the surface of the component to be inspected, preventing the component from sliding or rotating during clamping or adjustment, and ensuring positioning stability. Secondly, the soft texture of the rubber prevents the hard metal clamp 22 from directly contacting the surface of the component, preventing scratches or damage to the delicate coating layer of the component during clamping.

[0026] Specifically, the top of the inner side of the first frame 4 is provided with left and right sliding openings that are adapted to the slider 8.

[0027] It should be noted that the left and right sliding ports provide precise linear guidance constraints for the slider 8 and the entire motion module connected above it, restricting its motion freedom to the strict left and right directions.

[0028] Specifically, the inner sides of the left and right second frames 10 are provided with front and rear movable openings that are adapted to the connecting block 16, and the front and rear movable opening on the left side is arranged on the right side of the left second frame 10, and the front and rear movable opening on the right side is arranged on the left side of the right second frame 10.

[0029] It should be noted that the front and rear movable openings are designed to allow the connecting block 16 to drive the fixed block 17 and the placement components on it to move back and forth.

[0030] Specifically, the left end of the first threaded rod 6 passes through the right side wall of the first frame 4 and the threaded groove of the first threaded block 7 in sequence, and is rotatably connected to the inner left side wall of the first frame 4.

[0031] Specifically, one end of the front of the second threaded rod 12 passes through the front of the left second frame 10 and the threaded groove of the second threaded block 13 in sequence, and is rotatably connected to the inner rear side wall of the left second frame 10.

[0032] The working principle of the above embodiments is as follows:

[0033] The operator places the automotive parts to be inspected on the placement plate 20. The second electric push rods 21 on the left and right sides are activated, and their movable rods extend, pushing the clamping plates 22 to move towards each other, clamping the parts to be inspected through the rubber pads on the clamping plates 22;

[0034] The first electric push rod 19 is activated, and through the extension and retraction of its movable rod, the placement plate 20 and the clamped component are driven to move up and down as a whole. This action is used to significantly adjust the height of the component so that the surface to be measured is roughly within the depth of field of the inspection camera 3, in preparation for subsequent fine focusing;

[0035] The first motor 5 is started, driving the first threaded rod 6 to rotate. The first threaded block 7, which is threaded with the first threaded rod 6, converts the rotational motion into linear motion. The first threaded block 7 drives the slider 8 to move precisely left and right along the left and right sliding openings at the top of the first frame 4. This motion is transmitted through the fixing plate 9 to the entire upper second frame 10, the placement components and the clamped parts, realizing the horizontal position adjustment of the parts and moving the measured area horizontally to below the detection camera 3.

[0036] The second motor 11 is started, driving the second threaded rod 12 to rotate. The second threaded block 13, which is threaded with the second threaded rod 12, converts the rotational motion into linear motion, driving the left connecting block 16 to move back and forth. At the same time, the right connecting block 16 slides on the guide rod 14 to provide auxiliary support. The connecting blocks 16 on both sides synchronously drive the fixed block 17 and the entire placement assembly and components on it to move back and forth along the front and rear movable openings, realizing the position adjustment of the components in the front and rear directions, and finally aligning the area to be measured with the center of the field of view of the detection camera 3.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
