DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a welding robot visual sensing device with automatic focus, comprising a robotic arm 1, a controller 2 fixed to the top of the robotic arm 1, an adjustment component 200 for adjustment installed at the bottom of the robotic arm 1, a moving component 300 for movement installed at the bottom of the robotic arm 1, and a stabilizing component 400 for making the adjustment more stable.

[0024] Through the coordinated use of the robotic arm 1, the controller 2, the adjustment component 200, the moving component 300 and the stabilizing component 400, the welding robot visual sensing device can achieve automatic focus during actual use, thereby eliminating the need for manual buttons or other mechanical switches to achieve focus alignment, saving labor costs, and effectively improving the work efficiency of the welding robot, thereby improving the practicality of the welding robot visual sensing device with automatic focus.

[0025] In this embodiment, the adjustment component 200 is a structure for performing adjustment.

[0026] like Figure 1 and 3 As shown, the adjustment component 200 includes a fixed block 201 fixed to the bottom of the robotic arm 1, a mounting hole 202 is provided on the left side of the fixed block 201, an adjustment cylinder 203 is fixed inside the mounting hole 202, the internal thread of the adjustment cylinder 203 is connected to a screw 204, two limit slots 205 are provided on the left side of the fixed block 201, the internal sliding connection of the limit slot 205 is connected to the limit block 206, and a motor 207 is fixed to the left end of the screw 204.

[0027] It should be noted that the two limiting blocks 206 are fixed on opposite sides to the top and bottom of the adjusting tube 203 respectively, to ensure that the limiting blocks 206 can effectively limit the adjusting tube 203 .

[0028] In addition, the adjustable distance of the screw 204 in the adjusting cylinder 203 is smaller than the adjustable distance of the limit block 206 in the limit groove 205, which effectively avoids the screw 204 and the adjusting cylinder 203 from falling off during the adjustment process. The right side of the motor 207 is fixed to the left side of the fixing block 201, making the installation of the motor 207 more stable.

[0029] In this embodiment, the moving component 300 is a structure for moving.

[0030] like Figure 1 、 Figure 2 and 3 As shown, the moving assembly 300 includes a fixed frame 301 fixed to the right end of the adjusting cylinder 203, the internal sliding connection of the fixed frame 301 is connected to the adjusting block 302, the internal sliding connection of the adjusting block 302 is connected to two limit rods 303, and the back of the adjusting block 302 is fixed to an electric push rod 304.

[0031] It should be noted that the end of the electric push rod 304 away from the adjustment block 302 is fixed to the fixed frame 301 to fix the electric push rod 304. The visual sensor 3 is fixed to the right side of the adjustment block 302 to ensure that the visual sensor 3 can be effectively adjusted through the adjustment block 302 to achieve focusing.

[0032] In addition, the limiting rod 303 is fixed inside the fixing frame 301 , ensuring that the adjusting block 302 can slide more stably in the fixing frame 301 through the limiting rod 303 .

[0033] In addition, the output end of the visual sensor 3 is connected to the input end signal of the controller 2 to ensure that the image collected by the visual sensor 3 can be transmitted to the display screen of the welding robot through the controller 2. The controller 2 is electrically connected to the motor 207 and the electric push rod 304 respectively to ensure that the controller 2 can control the motor 207 and the electric push rod 304 when needed during the focusing process, thereby realizing automatic adjustment of the visual sensor 3 and realizing automatic focusing.

[0034] In this embodiment, the stabilizing assembly 400 is a structure used to provide a more stable structure during adjustment.

[0035] like Figure 1 and 3 As shown, a fixing plate 401 is fixed to the bottom of the fixing frame 301 , a fixing rod 402 is fixed to the left side of the fixing plate 401 , a fixing ring 403 is fixed to the bottom of the fixing frame 301 , and a limiting plate 404 is fixed to the left end of the fixing rod 402 .

[0036] It should be noted that the inner diameter of the fixing ring 403 is equal to the diameter of the fixing rod 402, so that the fixing rod 402 can slide more stably in the fixing ring 403, and the diameter of the limiting plate 404 is larger than the inner diameter of the fixing ring 403, which effectively prevents the fixing ring 403 and the fixing rod 402 from falling off.

[0037] The working principle of the above embodiment is:

[0038] During use, the welding robot obtains an image through the visual sensor 3 during the actual process and transmits the image to the display screen of the welding robot. When the image is not clear and needs to be focused, the motor 207 is turned on by the controller 2 to drive the screw 204 to rotate, and the adjusting cylinder 203 is moved left and right on the outside of the screw 204 under the action of the internal thread rotation thrust and the limiting action of the limit block 206, thereby driving the visual sensor 3 to move left and right. When the visual sensor 3 needs to be adjusted forward and backward, the electric push rod 304 is turned on by the controller 2, and the visual sensor 3 is driven to move forward and backward by the electric push rod 304 and the adjustment block 302. It can ensure that the position of the visual sensor 3 is automatically adjusted according to the actual situation, thereby achieving automatic focusing, and under the action of the fixed rod 402, the fixed ring 403 and the fixed plate 401, the position of the visual sensor 3 is more stable when adjusted.

[0039] Compared with the existing technology, the automatic focusing welding robot visual sensing device, through the coordinated use of the mechanical arm 1, the controller 2, the visual sensor 3, the adjustment component 200, the moving component 300 and the stabilizing component 400, can enable the welding robot visual sensing device to achieve automatic focusing during actual use, thereby eliminating the need for manual buttons or other mechanical switches to achieve focal length alignment, saving labor costs, and effectively improving the working efficiency of the welding robot, improving the practicality of the automatic focusing welding robot visual sensing device, and solving the problem of low practicality of the existing welding robot visual sensing device.
