[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments are not intended to limit the present invention.

[0028] Reference Figure 1-Figure 5 As shown, the present invention is based on a variable-distance multi-station gluing visual inspection mechanism,

[0029] include:

[0030] A mounting plate 1, with a first gluing mechanism 2 and a second gluing mechanism 3 respectively disposed on both sides of the mounting plate 1;

[0031] A driving member 5, at least one glue coating mechanism is connected to the output end of the driving member 5, and the driving member 5 can drive the first glue coating mechanism 2 and / or the second glue coating mechanism 3 to move along the first direction;

[0032] The glue coating mechanism includes a support frame 21, which is movably connected to a visual camera 25 along the second direction. The support frame 21 is provided with a glue gun 22, which is drivably connected to a glue coating head 29 along the second direction. The first direction and the second direction are perpendicular to the plane.

[0033] The present invention discloses a visual inspection mechanism based on variable-distance multi-station gluing. An external manipulator is connected to the mounting plate 1, and two gluing stations are arranged on the mounting plate 1. The driving member 5 is used to drive the first gluing mechanism 2 and / or the second gluing mechanism 3 to move along a first direction (left and right direction in the present embodiment), and the distance between the two groups of gluing mechanisms is adjusted. The glue gun 22 is used to evenly apply the glue to the surface of the workpiece through the gluing head 29. The manipulator is used to control the entire gluing mechanism to move back and forth to apply glue on the product. During gluing, the visual camera 25 is used to detect the quality of the glue, such as the thickness and uniformity of the glue layer, and whether there is glue leakage. The visual camera 25 is movably arranged on the support frame 21 along the up and down directions (up and down directions in the present embodiment). The functions of multi-station gluing and variable-distance gluing enable the mechanism to adapt to the gluing needs of objects of different shapes and sizes. Through visual inspection while gluing, problems occurring during the gluing process can be discovered and solved in a timely manner, thereby improving the efficiency and quality of gluing, reducing the work cycle time, and improving work efficiency.

[0034] Reference Figure 3 As shown, the support frame 21 is provided with a second support body 26 and a second telescopic driving member 27 along the second direction, and the visual camera 25 is slidably connected to the second support body 26 and connected to the power output end of the second telescopic driving member 27. The visual camera 25 is driven by the second telescopic driving member 27 to slide along the second direction on the second support body 26, thereby maintaining a suitable distance from the product to be inspected, so that the inspection camera and the area to be inspected remain in focus.

[0035] Reference Figure 5 As shown, light sources 28 are provided on both sides of the visual camera 25, and supplementary light is provided to the visual camera 25 through power supply to adapt to the insufficient lighting environment or the situation where the lighting in the inner recess is weak due to the structural characteristics of the product.

[0036] Reference Figure 4 As shown, a glue connecting component 4 is movably provided on one side of the glue coating head 29, and the glue connecting component 4 can be moved to the bottom of the glue coating head 29. After the gluing of a group of products is completed, when the gluing mechanism needs to be moved to another product by a robot, the glue connecting component 4 is moved to the bottom of the glue coating head 29 to collect the fallen glue to prevent glue dripping from contaminating the product or the production environment.

[0037] Continue to refer to Figure 4As shown, the support frame 21 is respectively provided with a first support body 23 and a first telescopic driving member 24 along the second direction, and the glue joining component 4 is slidably connected to the first support body 23 and connected to the output end of the first telescopic driving member 24. The glue joining component 4 is driven to move along the second direction by the first telescopic driving member 24, and the distance between the glue joining component 4 and the glue joining cup 44 in the height direction can be increased to adapt to glue joining heads of different lengths and shapes.

[0038] The first support body 23 is provided with a third telescopic driving member 41 along the third direction, and the support seat 42 is provided with a third support body 43. The support seat 42 is slidably connected to the first support body 23 through the third support body 43. The support seat 42 is connected to the output end of the third telescopic driving member 41, and the glue connecting cup 44 is driven by the third telescopic driving member 41 to avoid or connect with the glue coating head 29 in the third direction (the front and back direction in this embodiment).

[0039] Reference Figure 4 As shown, the glue connecting component 4 includes: a support seat 42 movably connected to the output end of the first telescopic driving member 24 along a third direction, and a glue connecting cup 44 arranged on the support seat 42. The support seat 42 is driven to move along the third direction by the first telescopic driving member 24, and drives the glue connecting cup 44 to move accordingly.

[0040] The glue receiving cup 44 is detachably disposed on the support seat 42 , so as to facilitate replacement of glue receiving cups 44 of different sizes and removal of the glue receiving cup 44 for emptying.

[0041] In this embodiment, the first support body 23, the second support body 26 and the third support body 43 are all composed of limiting slide rails and sliders, so that the structure fixed at the end of the slider can only move along the direction of the corresponding slide rail. Correspondingly, the first telescopic drive member 24, the second telescopic drive member 27 and the third telescopic drive member 41 are one or more of driving cylinders, linear motors, and hydraulic cylinders. In this embodiment, cylinders are preferred, which have fast response speeds, low weight, and low requirements on the structural strength and load-bearing burden of the manipulator.

[0042] A bottom plate 7 is provided at the end of the support seat 42, and a cover plate 8 is rotatably connected to the bottom plate 7. The free end of the cover plate 8 is clamped on the bottom plate 7. A ring body extends outward from the mouth of the glue cup 44, and the ring body is crimped between the cover plate 8 and the bottom plate 7. When the glue cup 44 needs to be removed, the cover plate 8 is opened to release the lock of the glue cup 44. When the glue cup 44 needs to be placed, the ring body is placed on the opening of the bottom plate 7, and the cover plate 8 is pressed down so that the ring body of the glue cup 44 is crimped under the cover plate 8.

[0043] The mounting plate 1 is provided with a mounting flange 6, and the mounting plate 1 is connected to the manipulator to be connected via the mounting flange 6. The manipulator drives the entire gluing visual inspection mechanism to move to a designated working position by connecting to the mounting flange 6 on the mounting plate 1. During the working process, the manipulator controls the position and posture of the gluing visual inspection mechanism according to the preset program and trajectory, so that it can accurately perform gluing operations on the object to be glued.

[0044] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
