Detailed Implementation

[0028] 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.

[0029] Example 1

[0030] like Figures 1 to 5 As shown, a six-axis robot workstation based on automatic welding of electrode mesh is provided. The workstation includes two sets of symmetrically arranged electrode frame assembly positioning and rotation mechanisms, and a displacement clamping mechanism and a welding mechanism are arranged between the two sets of symmetrically arranged electrode frame assembly positioning and rotation mechanisms.

[0031] The positioning and rotating mechanism of the electrode frame assembly includes a circular platform 12, which is rotatably mounted on a rotating steel frame 1. The circular platform 12 is used to place the limiting electrode mesh assembly. The top of the rotating steel frame 1 is rotatably connected to the circular platform 12 via a support bearing. The displacement and clamping mechanism includes a flipping arm 22, which is flipped and mounted on a flipping structural frame 2. A clamping bracket is mounted on the flipping arm 22, and two movable clamping plates 26 are mounted on both ends of the clamping bracket. The clamping plates 26 are used to clamp the electrode mesh assembly on the circular platform 12.

[0032] In this embodiment, the electrode mesh assembly to be processed is placed on the circular platform 12 of the workstation, and the circular platform 12 is used to limit and fix the electrode mesh assembly. Then, the circular platform 12 is rotated to a suitable angle, and the flipping arm 22 is controlled to flip and adjust. Then, the pressing plate 26 connected to the pressing bracket on the flipping arm 22 is adjusted to press the circular platform 12 to press the electrode mesh assembly. Finally, the welding mechanism is controlled to weld the electrode mesh assembly on the circular platform 12.

[0033] Example 2

[0034] Based on Embodiment 1, the support bearing of this configuration is connected to a rotating shaft, the top of which is connected to a circular platform 11; a large rotating gear 17 is connected to the rotating shaft, the large rotating gear 17 meshes with a small driving gear 16, and the small driving gear 16 is connected to the output end of a servo motor 18 through the rotating shaft, and the servo motor 18 is mounted on the rotating steel structure frame 1.

[0035] Meanwhile, a number of positioning blocks 13 are installed around the end face of the circular platform 12 away from the rotating steel structure frame 1 to limit the electrode grid assembly on the circular platform 12; a number of clamping cylinders 14 are also installed around the circular platform 12 to clamp and limit the electrode grid assembly on the circular platform 12.

[0036] In this embodiment, a servo motor 18 mounted on the rotating steel frame 1 drives a small drive gear 16 to rotate, which in turn drives a large rotating gear 17 that meshes with it to rotate. Simultaneously, the large rotating gear 17 is rotatably connected to the rotating steel frame 1 via a support bearing. The rotation of the large rotating gear 17 drives the rotating shaft connected to the support bearing to rotate, which in turn drives the circular platform 12 connected to the top of the rotating shaft to rotate to a suitable angle. This facilitates the pressure plate 26 to control and press the electrode mesh assembly on the circular platform 12, and the welding mechanism to weld the electrode mesh assembly on the circular platform 12.

[0037] Example 3

[0038] The rotating arm 22 is movably sleeved on the rotating shaft, and a spring is sleeved on the rotating shaft. One end of the spring is connected to the rotating shaft, and the other end of the spring is elastically connected to the rotating arm 22. Limit seats are respectively provided at both ends of the rotating shaft, and the limit seats are respectively connected to the rotating structure frame 2. The rotating shaft passes through the limit seats rotatably through bearings, and one end of the rotating shaft is connected to the output end of the rotating servo motor 24, which is mounted on the rotating structure frame 1.

[0039] Meanwhile, positioning cylinders 23 are respectively installed on both ends of the flipping shaft. The cylinder bodies of the positioning cylinders 23 are fixed to the flipping structure frame 2 by bolts. The output rods of the positioning cylinders 23 are respectively connected to positioning pins 25. Positioning holes are opened on both sides of the clamping bracket installed on the flipping arm 22. After the flipping arm 22 flips through the clamping bracket and reaches the position above the electrode mesh assembly on the circular platform 12, the positioning cylinders 23 extend to push the positioning pins 25 into the positioning holes opened in the side wall of the clamping bracket, thereby realizing the positioning adjustment of the clamping plate 26. The clamping plates 26 installed on both sides of the clamping bracket are telescopically connected to the clamping bracket through clamping telescopic cylinders 27.

[0040] In this embodiment, the flipping servo motor 24 drives the flipping shaft to rotate around the limiting seat set in the flipping structure frame 1, thereby driving the flipping arm 22 on the flipping shaft to rotate. This places the clamping plate 26 on the flipping arm 22, which is connected to the clamping bracket, above the circular platform 12 of one of the pole frame assembly positioning and rotating mechanisms. At this time, the pole mesh assembly for processing is positioned at the upper limit of the circular platform 12. Then, the positioning cylinders 23 at both ends on the same side of the flipping shaft are controlled to move. By extending the positioning cylinders 23, the positioning pins 25 are pushed into the positioning holes opened in the side wall of the clamping bracket. According to the position of the pole mesh assembly currently limited on the circular platform 12, the "extension and contraction" of the positioning cylinders 23 is used to adjust the flipping arm 22 to move along the flipping shaft, ultimately adjusting the clamping plate 26 to a suitable position above the circular platform 12. Then, by extending the clamping extension cylinder 27, the clamping plate 26 is moved towards the pole mesh assembly positioned at the upper limit of the circular platform 12, clamping the pole mesh assembly. Subsequently, the welding mechanism begins to perform welding operations.

[0041] Example 3

[0042] The welding mechanism of this setup is located at one end of the flipping arm 22; the welding mechanism includes a welding robot arm 32; the welding robot arm 32 is mounted and connected to the robot base 31, and is anchored to the ground through the robot base 31; the other end of the welding robot arm 32 is mounted and connected to a connecting seat 33 that can move together with the welding robot arm 32; welding equipment 35 and 3D vision system 34 are respectively mounted and connected on the connecting seat 33.

[0043] In this embodiment, the electrode mesh assembly on the circular platform 12 is fully welded by controlling the rotation of the circular platform 12 and by adjusting the welding mechanism during welding. The welding operation is performed by the welding equipment 35 connected to the welding robot arm 32 of the welding mechanism. The 3D vision system 34 (existing technology) is used to scan and track the electrode mesh assembly and the weld seam of the electrode mesh assembly. The electrode mesh assembly is fully welded by controlling and adjusting the welding robot arm 32.

[0044] In this system, after the electrode mesh assembly at the upper limit of the circular platform 12 on the electrode frame assembly positioning and rotating mechanism of one workstation is welded, the flipping arm 22 of the displacement and pressing mechanism is flipped. Adjusting the flipping arm 22 according to the above embodiments (Embodiments 1, 2, and 3) presses the electrode mesh assembly at the upper limit of the circular platform 12 on the electrode frame assembly positioning and rotating mechanism of the other workstation. The welding robot arm 32 of the welding mechanism, equipped with a connected welding device 35, welds the electrode mesh assembly at the upper limit of the circular platform 12 on the other workstation. The two workstations can perform pressing and welding operations without affecting each other, thus not impacting the production cycle. Furthermore, a safety fence 6 is installed in the entire workstation's working area to ensure production safety. The workstation control cabinet 4 is placed in the workstation's blind spot. The entire system's workstation control cabinet 4 and operating interface 5 are placed in a location easily accessible to control within the safety fence 6, facilitating manual operation.
