[0020] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 3 As shown, the utility model provides a self-circulating transmission line of a welding mechanism. In one embodiment, it includes a mounting base plate 1, a material discharge lifting mechanism 2 installed at one end of the mounting base plate 1, a material receiving lifting mechanism 3 installed at the other end of the mounting base plate 1, a loading transmission mechanism 4 installed at the top of the mounting base plate 1 and located between the material discharge lifting mechanism 2 and the material receiving lifting mechanism 3, and a reflux transmission mechanism 5 installed at the bottom of the mounting base plate 1 and located between the material discharge lifting mechanism 2 and the material receiving lifting mechanism 3; the loading transmission mechanism 4 includes two loading transmission frames arranged in parallel and spaced relation at the top of the mounting base plate 1, a loading conveyor belt module installed on the loading transmission frame, and a transmission motor assembly installed on the loading transmission frame and connected to the loading conveyor belt module; a lifting and positioning mechanism 6 is also installed on the top of the mounting base plate 1, and the lifting and positioning mechanism 6 is arranged between the two loading transmission frames; a first blocking mechanism 7 is also installed on one side of the lifting and positioning mechanism 6.

[0022] Continue to refer to Figure 1 As shown, in this embodiment, there are three lifting and positioning mechanisms 6, and the three lifting and positioning mechanisms 6 are arranged between the two loading and conveying racks at intervals in the length direction of the installation base plate 1 (that is, there are three welding stations, each welding station welds a welding point of the product, and each lifting and positioning mechanism 6 is arranged at a welding station), and a first blocking mechanism 7 is arranged on one side of each lifting and positioning mechanism 6; at the same time, three second blocking mechanisms 8 are also provided (the installation position of each second blocking mechanism 8 is a cache station), wherein one is arranged between each adjacent lifting and positioning mechanisms 6, and the other second blocking mechanism 8 is arranged on one side of the material receiving lifting mechanism 3; the first blocking mechanism 7 and the second blocking mechanism 8 both include a first blocking cylinder.

[0023] During operation, first, a manual or external robot places the product on the carrier, and then moves the carrier to the unloading lifting mechanism 2. The unloading lifting mechanism 2 transports the carrier to the loading conveying mechanism 4; the loading conveying mechanism 4 then transports the carrier to welding position No. 1 (for ease of description, Figure 1 From left to right in the figure, the positions of the three lifting and positioning mechanisms 6 are welding position No. 1, welding position No. 2 and welding position No. 3 respectively), and at the same time, the unloading lifting mechanism 2 descends to wait for the recovery of the carrier; then, the first blocking mechanism 7 at welding position No. 1 blocks the carrier, and the lifting and positioning mechanism 6 lifts the carrier to detach it from the feeding conveyor belt module; then, the welding mechanism at welding position No. 1 welds one of the points of the product, and after the welding is completed, the lifting and positioning mechanism 6 and the first blocking mechanism 7 descend, and the carrier follows the feeding conveyor mechanism 4 to flow to the first cache station for storage; if there is a carrier at welding position No. 2, the second blocking mechanism 8 located at the first cache station blocks the carrier, if there is no carrier at welding position No. 2, the second blocking mechanism 8 descends, and the carrier follows the feeding conveyor mechanism 4 to flow to welding position No. 2, and the first blocking mechanism 7 at welding position No. 2 blocks the carrier, and the lifting and positioning mechanism 6 lifts the carrier to wait for the welding mechanism to weld another welding point of the product, so as to realize the welding of 3 welding points in this cyclic operation.

[0024] After the welding mechanism at welding position No. 3 completes welding of the product, the carrier flows to the material receiving lifting mechanism 3, the material receiving lifting mechanism 3 descends, and transfers the carrier to the reflux transmission mechanism 5, and the reflux transmission mechanism 5 then transports the carrier to the material discharging lifting mechanism 2, the material discharging lifting mechanism 2 rises, and a manual or robotic arm takes away the welded product, and then puts in a new product, thereby realizing the cyclic operation of the carrier; in this embodiment, the structure and working mode of the reflux transmission mechanism 5 are similar to those of the feeding transmission mechanism 4, and are not repeated here. At the same time, two third blocking mechanisms 9 are also installed on one end of the reflux transmission mechanism 5 close to the material receiving lifting mechanism 3, and the third blocking mechanism 9 serves as a blocking cache to prevent the carrier from being transferred to the material receiving lifting mechanism 3 in advance.

[0025] In one embodiment, the lifting and positioning mechanism 6 includes a first bottom plate 61 installed on the top of the installation bottom plate 1, a first fixed plate 62 arranged above the first bottom plate 61, a lifting cylinder 63 installed between the first bottom plate 61 and the first fixed plate 62, a first connecting rod 64 connected to the output shaft of the lifting cylinder 63, and a first lifting plate 65 arranged above the first fixed plate 62 and connected to the first connecting rod 64. The carrier is arranged on the first lifting plate 65, and under the drive of the lifting cylinder 63, the first lifting plate 65 can be driven by the first connecting rod 64 to drive the carrier to rise, so as to weld the product. At the same time, a positioning pin 66 is also installed at each of the four corners of the top of the first lifting plate 65. Positioning holes are provided at the four corners of the bottom of the carrier corresponding to the positioning pins 66, so that the carrier can be quickly positioned when it is lifted. In addition, a linear bearing 67 is installed at each of the four corners of the first fixed plate 62, and a lifting guide rod 68 is installed on each linear bearing 67; the top of the lifting guide rod 68 is connected to the bottom of the first lifting plate 65. When the carrier is lifted, it can be guided by the lifting guide rod 68 to improve the stability of its movement. A first position sensor 69 is also installed on the top of the first fixed plate 62, and a first through hole is provided at the top of the first lifting plate 65 corresponding to the first position sensor 69. The first position sensor 69 can detect whether the carrier is in place.

[0026] In one embodiment, a second through hole is respectively provided at both ends of the top of the mounting base plate 1; the material discharge lifting mechanism 2 and the material collection lifting mechanism 3 both include a first mounting frame 21, a Z-axis lifting mechanism 22, and a transfer transmission mechanism 23; the upper part of the first mounting frame 21 is arranged through the second through hole, and a first connecting seat 24 connected to the top of the mounting base plate 1 is also installed on one side of the upper part of the first mounting frame 21; the Z-axis lifting mechanism 22 is installed on the other side of the first mounting frame 21, and the Z-axis lifting mechanism 22 is also driven and connected to a Z-axis lifting frame 25; the transfer transmission mechanism 23 is installed on the Z-axis lifting frame 25.

[0027] In this embodiment, the Z-axis lifting mechanism 22 adopts a linear module, and the transfer transmission mechanism 23 adopts a conventional conveyor belt assembly line, which is not limited. At the same time, a limit rod 26 is also installed at one end of the top of the transfer transmission mechanism 23; and a second position sensor 27 is also installed on the Z-axis lifting frame 25. The limit rod 26 can limit the carrier transported to the transfer transmission mechanism 23 to prevent it from falling from the transfer transmission mechanism 23. At the same time, the second position sensor 27 can detect whether the carrier is in place, so that the background control system can perform the next step of motion control.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
