[0001] This utility model relates to the field of multi-station assembly machine technology, specifically a vision inspection mechanism for multi-station assembly machines. Background Technology

[0002] When assembling workpieces in a multi-station manner, a vision inspection mechanism is required to detect the position of the parts after each step of assembly. The vision inspection mechanism is integrated into the multi-station automatic assembly machine for real-time positioning, assembly quality inspection, error prevention and correction, ensuring assembly accuracy and yield.

[0003] The existing assembly equipment's inspection mechanism requires positional adjustments between processing stations to perform precision inspections on parts at different stations. However, during the inspection process, highly reflective metal surfaces (such as polished screws) may still produce specular reflections, leading to edge extraction errors. This can cause deviations in the inspection of the mating positions of the parts, affecting the accuracy of subsequent product processing and inspection. It may result in product damage or require rework and adjustment, impacting assembly efficiency. Therefore, optimization and improvement are needed. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 5 As shown, this application provides a multi-station assembly machine visual inspection mechanism, including: an assembly machine base 1, a processing turntable 2 connected to the middle of the top of the assembly machine base 1, a parts transfer frame 3 connected to the outer side of the top of the assembly machine base 1, and an inspection mounting frame 4 installed in front of the top of the assembly machine base 1.

[0026] The inner side of the inspection mounting frame 4 is provided with an inspection adjustment component, which includes a rotating pressure plate 6, and a sliding frame 8 is provided at the bottom of the rotating pressure plate 6. A slider 9 is provided inside the sliding frame 8, and an inspection head 11 is provided at the front end of the slider 9. The inspection adjustment component is used to adjust the inspection position of the part.

[0027] Specifically, such as Figure 2 As shown, the rear end of the testing mounting frame 4 is connected to a telescopic cylinder 5, and a rotating pressure plate 6 is connected to the top of the telescopic cylinder 5. The rotating pressure plate 6 and the testing mounting frame 4 are rotatably connected. When the telescopic cylinder 5 moves upward, the end of the rotating pressure plate 6 presses down, pushing the elastic connecting rod 10.

[0028] Specifically, such as Figure 2 As shown, a fixing block 7 is installed at the front end of the testing mounting bracket 4, and a sliding frame 8 is slidably connected to the inner side of the fixing block 7. The fixing block 7 can be adjusted to slide inside the sliding frame 8.

[0029] Specifically, such as Figure 3As shown, the top of the slider 9 is connected to an elastic connecting rod 10. The elastic connecting rod 10 is connected to the slider 9 and can control the up and down position of the detection head 11.

[0030] Specifically, such as Figure 3 As shown, a telescopic cylinder 12 is installed at the bottom of the sliding frame 8, and a buffer guide rod 13 is connected to the outside of the telescopic cylinder 12. The telescopic cylinder 12 drives the buffer guide rod 13 to move, which will cause the sliding frame 8 to slide, thus controlling the position of both ends of the detection head 11.

[0031] The top of the mounting bracket 4 is equipped with a light source adjustment component, which includes a top plate 14, a light shield 17 at the top of the top plate 14, and a ring light 21 at the bottom inner side of the top plate 14. The light source adjustment component is used to adjust the lighting position of the light source.

[0032] Specifically, such as Figure 4 As shown, the top plate 14 is connected to the top of the detection mounting frame 4, and rollers 15 are connected to both sides of the top plate 14. The rollers 15 are used to support the light shield 17 and reduce the friction of the light shield 17 during movement.

[0033] Specifically, such as Figure 4 As shown, a telescopic cylinder 16 is connected to the top of the top plate 14, and a light-shielding plate 17 is connected to the outside of the telescopic cylinder 16. The telescopic cylinder 16 controls the light-shielding plate 17 to extend outward, increasing the light-shielding area of ​​the top plate 14.

[0034] Specifically, such as Figure 5 As shown, a spherical connecting seat 18 is connected to the bottom inner side of the top plate 14, and an adjusting seat 19 is connected to the bottom of the spherical connecting seat 18. A rubber ball sleeve 20 is connected to the inner side of the adjusting seat 19. The ring light 21 is installed at the bottom of the adjusting seat 19. The spherical connecting seat 18 and the adjusting seat 19 are connected by rotation. The spherical setting can be adjusted arbitrarily within a certain range. The inner rubber ball sleeve 20 can increase the friction of rotation, improve the positioning effect after rotation, and control the angle of the ring light 21.

[0035] In this embodiment: by rotating the pressure plate 6 to control the position of the slider 9, the up and down position of the detection head 11 is adjusted. The buffer guide rod 13 inside the fixed block 7 controls the sliding frame 8 to move left and right. During the detection process, the range of the detection head 11 can be adjusted to avoid mirror reflection, which facilitates the smooth progress of the detection work. When external light sources are unavoidable, a combination of a top plate 14 and a light shield 17 is provided at the top to block the external light sources. The internal ring supplement light 21 can be adjusted in position by connecting the spherical connecting seat 18 and the adjusting seat 19 to achieve a suitable position.

[0036] Specifically, this solution involves the following: When processing on a five-station assembly machine, the parts transfer rack 3 is used to assemble and transfer parts on the processing turntable 2. During use, the assembly effect needs to be checked by the inspection head 11. Because the processed metal has a reflective effect, one end of the rotating pressure plate 6 can be moved by the telescopic cylinder 5, and then the other end squeezes the elastic connecting rod 10 and the slider 9. This allows the vertical position of the inspection head 11 to be adjustable. Then, the telescopic cylinder 2 controls the position of the buffer guide rod 13, and the position of the inspection head 11 is controlled by controlling the left and right position of the sliding frame 8, so that the inspection head 11 can avoid the reflection during inspection. When it is impossible to avoid the reflection, the telescopic cylinder 3 16 drives the light shield 17 to expand outward, so that the top plate 14 and the light shield 17 extend to block the external light source. The ring supplement light 21 at the bottom is used as a substitute. The ring supplement light 21 can be adjusted within a certain range under the spherical rotation connection of the spherical connecting seat 18 and the adjusting seat 19, which facilitates the accurate detection of the inspection head 11 and improves the product production quality.

[0038] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
