Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] like Figures 1 to 4 As shown, an automated ultrasonic welding robot has undergone a series of design improvements on the original structure, enabling it to move freely to weld components. The improved welding robot includes a welding robotic arm (an existing robotic arm structure), with an adjustable ultrasonic welding instrument 1 connected to its top. The bottom of the welding robotic arm is movable relative to the ground via a movable mechanism. The movable mechanism includes a movable base 2, with an electrically driven rotating platform 3 connected to its top. The welding robotic arm is rotatably connected to the movable base 2 via the electrically driven rotating platform 3. An electric guide rail is connected to the bottom of the movable base 2, which is movablely connected to a support platform 4 via the electric guide rail. The support platform 4 is used for fixed connection to the ground.
[0024] In this embodiment, the ultrasonic welding device 1 is mounted on a welding robotic arm structure, which in turn is mounted on an electric rotary table 3 of a movable mechanism. Furthermore, the movable base 2 is slidably mounted on a support base 4 as needed. Simultaneously, the electric rotary table 3 is movably connected to the movable base 2 via an electric guide rail. By controlling the electric guide rail to maximize the movement of the welding robotic arm structure within the welding workshop (assembly line), and by controlling the movement of the welding robotic arm structure, the ultrasonic welding device 1 is moved to a suitable position. Then, the ultrasonic welding device 1 is controlled to automatically weld the parts to be welded, thereby improving welding efficiency.
[0025] Example 2
[0026] Based on implementation 1, the bottom end of the movable base 2 is also connected to a limiting slide rail 21. A sliding limiting block is slidably fitted into the limiting slide rail 21, and the sliding limiting block is used to connect and fix to the top surface of the support platform 4. By installing a paired "limiting slide rail 21 and sliding limiting block" between the movable base 2 and the support platform 4, when the electric guide rail drives the welding robotic arm structure to move, the paired "limiting slide rail 21 and sliding limiting block" provide stable limiting, ensuring stable movement of the welding robotic arm structure, ensuring the accuracy of its position adjustment, and thus ensuring the quality of the welded parts.
[0027] Furthermore, although the welding robotic arm structure is existing technology, improvements have been made to it. This welding robotic arm structure includes a welding connecting seat 5 and a connecting arm 6. The bottom end of the welding connecting seat 5 is rotatably connected to the electric rotary table 3, and one end of the connecting arm 6 is movably connected to the welding connecting seat 5 via a movable shaft. A movable servo motor 61 is mounted on the movable shaft to drive its movement, and the movable servo motor 61 is mounted on the connecting arm 6. By using existing technology, the welding connecting seat 5 and the electric rotary table 3 can be movably connected, enabling control of the movement of the welding connecting seat 5.
[0028] Meanwhile, the welding robotic arm structure also includes a telescopic arm 7; one end of the connecting arm 7 away from the welding connecting seat 5 is movably connected to one end of the telescopic arm 7 via a movable connecting shaft, and a telescopic servo motor 71 for driving the telescopic arm 7 is installed on the movable connecting shaft. The telescopic servo motor 71 is installed and connected to one end of the telescopic arm 7; the telescopic arm 7 is telescopic, and the other end of the telescopic arm 7 is used to connect to the ultrasonic welding instrument 1.
[0029] The connecting arm 7 and the telescopic arm 7 of the welding robotic arm structure can be "movably" connected using existing technology, enabling control of the "movement" of the telescopic arm 7. Furthermore, the ultrasonic welding instrument 1 is also "movably" connected to one end of the telescopic arm 7, thus enabling control of the welding robotic arm structure's "multi-degree-of-freedom" movement. This facilitates the control of the ultrasonic welding instrument 1 to move to the required position for welding the parts, thereby saving welding time and improving welding efficiency.
[0030] Example 3
[0031] Furthermore, an electrically driven rotating platform 8, which can extend and retract with the telescopic arm 7, is installed and connected to the end of the telescopic arm 7 away from the connecting arm 6. The electrically driven rotating platform 8 is rotatably connected to the ultrasonic welding instrument 1. A mounting bracket 9 is rotatably connected to the electrically driven rotating platform 8. The mounting bracket 9 is movable, and the ultrasonic welding instrument 1 is detachably connected to the mounting bracket 9 by bolts.
[0032] In this embodiment, by controlling the extension and retraction of the telescopic arm 7, the ultrasonic welding instrument 1 can be moved, thereby increasing the welding range of the ultrasonic welding instrument 1. Furthermore, the electric rotating platform 8 is used to control the movement of the mounting connector 9 using existing technology, thereby moving the ultrasonic welding instrument 1 on the mounting connector 9 to achieve further accurate adjustment and control of the welding position. In this embodiment, different ultrasonic welding instruments 1 can also be replaced as needed to meet welding requirements.
