[0029] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0030] Embodiment, referring to the attached Figure 1 ~Attached Figure 2 , The present invention provides a rotary metal mesh cover production line, which is used to produce a finished metal mesh cover 700 with the following structure: as shown in the attached Figure 4 As shown, the finished metal mesh cover 700 includes a plurality of metal rings 710 arranged in parallel in sequence from the inside to the outside and several metal connecting rods 720. The metal connecting rods 720 are fixedly connected to the metal rings 710. The metal connecting rods 720 are used to fix a plurality of metal rings 710 together. The two ends of the metal connecting rods 720 are provided with mesh cover mounting holes, and the mesh cover mounting holes are used to mount the finished metal mesh cover 700. The rotary metal mesh cover production line in this embodiment includes a rotary assembly line 100. The rotary assembly line 100 includes a rotating turntable 110 and a turntable driving device 120 for driving the rotating turntable 110 to rotate. The turntable driving device 120 generally adopts a structure of a motor cooperating with a reducer and can realize the uniform rotation of the rotating turntable 110. A plurality of assembly positioning fixtures 130 are arranged in a circular array on the rotating turntable 110. As shown in the attached Figure 3As shown in the figure, the assembly positioning fixture 130 includes a positioning base plate 131. On the upper end surface of the positioning base plate 131, there is a circular ring positioning groove 132 adapted to the aforementioned several metal rings 710. The positioning base plate 131 is also fixedly provided with a mounting hole positioning shaft 133 adapted to the mesh cover mounting holes of several metal connecting rods 720. Along the rotation direction of the rotary turntable 110, a first circular ring feeding device 200a, a second circular ring feeding device 200b, a connecting rod feeding device 200c, a welding machine 500, and a connecting rod bending device 600 are sequentially arranged on the outer side of the rotary turntable 110. The assembly positioning fixture 130 can sequentially pass through the first circular ring feeding device 200a, the second circular ring feeding device 200b, the connecting rod feeding device 200c, the welding machine 500, and the connecting rod bending device 600 driven by the rotary turntable 110;

[0031] The first circular ring feeding device 200a and the second circular ring feeding device 200b are used to place several metal rings 710 into the assembly positioning fixture 130 in two times. The structures of the first circular ring feeding device 200a and the second circular ring feeding device 200b are similar, and both include a multi-axis manipulator 210. Circular ring suction cups 220 are arranged at the action ends of the multi-axis manipulator 210. As shown in the attached Figure 7 figure, several circular ring adsorption blocks 221 are arranged in a circular array on the circular ring suction cup 220. Several circular ring adsorption positioning grooves 222 are arranged in parallel on the circular ring adsorption blocks 221. Adsorption holes 223 are arranged at the bottoms of the circular ring adsorption positioning grooves 222. The circular ring adsorption blocks 221 are connected to a negative pressure air source and can generate a negative pressure adsorption force through the adsorption holes 223. In this way, the workpieces in the circular ring adsorption positioning grooves 222 can be adsorbed by the negative pressure adsorption force of the adsorption holes 223. The difference is that the circular ring adsorption positioning grooves 222 of the first circular ring feeding device 200a are adapted to half of the metal rings 710 in the finished metal mesh cover 700, while the circular ring adsorption positioning grooves 222 of the second circular ring feeding device 200b are adapted to the remaining half of the metal rings 710 in the finished metal mesh cover 700. A first circular ring storage device 300a is arranged on one side of the first circular ring feeding device 200a, and a second circular ring storage device 300b is arranged on one side of the second circular ring feeding device 200b. The first circular ring storage device 300a and the second circular ring storage device 300b have similar structures as well. As shown in the attached Figure 5As shown in the figure, all of them include a circular ring storage bin 310. The circular ring storage bin 310 is provided with several circular ring storage grooves 320. Similar to the differences between the first circular ring feeding device 200a and the second circular ring feeding device 200b, the circular ring storage grooves 320 of the first circular ring storage device 300a are correspondingly adapted to half of the metal rings 710 in the finished metal mesh cover 700, while the circular ring storage grooves 320 of the second circular ring storage device 300b are correspondingly adapted to the remaining half of the metal rings 710. At the same time, the circular ring storage bin 310 is also provided with a circular ring pallet groove 330. A circular ring feeding pallet 340 is arranged in the pallet groove. A pallet driving device 350 is arranged on one side of the circular ring storage bin 310. The pallet driving device 350 is drivingly connected to the circular ring feeding pallet 340 and is used to drive the circular ring feeding pallet 340 to move along the circular ring pallet groove 330. Generally, a servo motor is used as the power source for the pallet driving device 350, and the power output by the servo motor is converted into a linear driving force through a precision lead screw. In this way, the circular ring feeding pallet 340 can be driven to achieve a step. Through software settings, the metal rings 710 required for each finished metal mesh cover 700 can be ejected each time, and then the first circular ring feeding device 200a and the second circular ring feeding device 200b are used for suction and discharging, so that all the metal rings 710 can be fed. The reason for feeding in two times is that the gap between the metal rings 710 is small. When feeding in one time, the distance between the circular ring adsorption positioning grooves 222 is too small, so there will be insufficient layout space for the negative pressure suction mechanism. At the same time, too many metal rings 710 at one time are also likely to cause insufficient negative pressure adsorption force and result in parts dropping off;

[0032] The connecting rod feeding device 200c also includes a multi-axis manipulator 210. However, different from the circular ring feeding device, several automatic clamps 230 are arranged at the action end of the multi-axis manipulator 210 of the connecting rod feeding device 200c. The automatic clamps 230 are used to clamp the metal connecting rods 720. A connecting rod storage device 400 is arranged on one side of the connecting rod feeding device 200c. As shown in the appendix Figure 6As shown in the figure, the connecting rod storage device 400 includes a connecting rod storage box 410. The connecting rod storage box 410 is provided with a connecting rod storage groove 420. The connecting rod storage box 410 is also provided with a connecting rod support plate groove 430. A connecting rod loading support plate 440 is arranged in the connecting rod support plate groove 430. A support plate driving device 350 is arranged on one side of the connecting rod storage box 410. The support plate driving device 350 is drivingly connected to the connecting rod loading support plate 440 and is used to drive the connecting rod loading support plate 440 to move along the connecting rod support plate groove 430. Similar to the principle of the ring loading device, the connecting rod loading support plate 440 can also eject the metal connecting rods 720 required for each finished metal mesh cover 700 under the drive of the support plate driving device 350, so as to facilitate the clamping and transfer of the above-mentioned connecting rod loading device 200c to the assembly positioning fixture 130. The mesh cover mounting holes of the metal connecting rods 720 are aligned and inserted into the mounting hole positioning shafts 133 of the assembly positioning fixture 130 to realize the positioning of the metal connecting rods 720;

[0033] The welding machine 500 is a prior art. The contact points between the metal connecting rods 720 and the metal rings 710 are welded together by spot welding to form semi-finished products;

[0034] As shown in the attached Figure 8 figure, the connecting rod bending device 600 includes a bending cylinder 610 and a bending positioning fixture 630. A bending block 620 is fixedly connected to the actuating end of the bending cylinder 610. The bending cylinder 610 is used to drive the bending block 620 to press against the bending positioning fixture 63,0. A semi-finished product transfer device 200d is arranged on one side of the connecting rod bending device 600. The semi-finished product transfer device 200d has the same structure as the connecting rod loading device 200c. The semi-finished product transfer device 200d also includes a multi-axis manipulator 210. Several automatic clamps 230 are arranged at the action end of the multi-axis manipulator 210. The semi-finished product transfer device 200d clamps the metal connecting rods 720 of the semi-finished products welded on the assembly positioning fixture 130 through the automatic clamps 230 and then clamps and places the semi-finished products on the bending positioning fixture 630. Then, the metal connecting rods 720 are bent at the specified positions by pressing down the bending block 620, and thus the processing of the finished metal mesh cover 700 is finally completed.

[0035] In this solution, the loading device of the workpiece is combined with the storage device to automatically complete the loading process in the production process of the finished metal mesh cover 700 without manual labor. Compared with the manual loading method, the speed is faster, and at the same time, the problem of missing single-piece placement will not occur, the cost is reduced, and the defective rate can also be reduced, which has good economic benefits.

[0036] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description.

Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution.
