[0002] like Figure 1 As shown, the metal mesh basket 1 of the present invention comprises a mesh container 11 and a reinforcement frame 12 welded to the top opening of the mesh container 11. The mesh container 11 is formed by bending and pressing the bottom mesh and the side mesh connected to the bottom mesh (the mesh structure is not shown in the figure). A docking area formed by overlapping two adjacent side meshes is formed at the four corners of the mesh container 11. This docking area needs to be welded to form a mesh container 11 with a firm structure. The reinforcement frame 12 is a square frame formed by bending a metal profile. The reinforcement frame 12 is formed with a clamping groove that matches the opening edge of the mesh container 11, so that the opening edge of the mesh container 11 is pressed into the clamping groove of the reinforcement frame 12, so as to fix the mesh container 11 and the reinforcement frame 12. The reinforcement frame 12 has a pair of seams that need to be welded, and burrs need to be removed after welding to form a qualified product. At present, each processing link of the metal mesh basket 1 is produced independently, and it also relies too much on manual operation, resulting in poor production continuity, which seriously affects production efficiency. Therefore, it is urgent to design a metal mesh basket production line to complete at least several consecutive processing steps among the above-mentioned multiple processing steps.

The conveyor line 21 is used to convey the metal mesh basket. The two side limit assemblies 22 are relatively mounted on the two sides of the conveyor line 21. The limiting width of the two side limit assemblies 22 is adapted to the width of the metal mesh basket, so that the metal mesh basket can move along the conveyor line 21 under the limiting action of the two side limit assemblies 22. The end limit piece 23 is arranged at the output end of the conveyor line 21 to block the metal mesh basket. The pushing assembly 24 is mounted on one side of the conveyor line 21 to push the metal mesh basket adjacent to the metal mesh basket blocked by the end limit piece 23, so that the two adjacent metal mesh baskets are separated by a specified distance to avoid hooking the adjacent metal mesh basket when taking out the metal mesh basket.

[0034] In the present embodiment, the conveyor line 21 adopts a roller conveyor line, which includes a conveyor frame, a plurality of rollers rotatably mounted on the conveyor frame, and a driving device for driving each roller to rotate.

[0039] In this embodiment, three groups of pushing components 24 are arranged along the conveying direction of the conveying line 21 to separate metal mesh baskets of different sizes.

[0040] The workpiece input positioning device 2 also includes a spacing adjustment mechanism 25 arranged below the top frame of the conveyor line 21. The conveyor line 21 adopts a roller conveyor line, so that the first limit member 221 passes through the roller interval through the support 223 and is fixed on the sliding end of the spacing adjustment mechanism 25, thereby adjusting the spacing between the first limit member 221 and the second limit member 222.

[0042] The workpiece input positioning device 2 is provided with two side limit assemblies 22, end limit pieces 23 and a pushing assembly 24 on the conveying line 21. The metal mesh basket is conveyed to the end limit pieces 23 under the limiting action of the two side limit assemblies 22 and stops moving, and two adjacent metal mesh baskets are separated by the pushing assembly 24. This makes it easier for the first manipulator 5 to grab the metal mesh basket parked at the end limit pieces 23, and avoids the metal mesh basket hooking the adjacent metal mesh basket when taking away to cause a malfunction.

[0043] The first welding machine 3 includes a welding electrode that can be raised and lowered and translated, and the butt joint of the reinforced frame 12 of the metal mesh basket is welded by controlling the movement of the welding electrode.

In this way, the front positioning member 43 and the rear positioning member 44 respectively clamp the two sides of the metal mesh basket for positioning.

[0046] The clamping assembly 45 includes a clamping cylinder and a clamping block. The clamping cylinder is fixed on the carrying platform 42 and close to one end of the first welding machine 3.

[0056] See also Fig.12 The third manipulator 9 is similar to the first manipulator 5, but the two gripping methods are different. The first manipulator 5 clamps the reinforcement frame 12 of the metal mesh basket from the top downward, while the third manipulator 9 extends from one end of the metal mesh basket and clamps the reinforcement frame 12 of the metal mesh basket. The two clamping arms 91 of the third manipulator 9 are relatively long, and the clamping grooves 90 on the clamping arms 91 are provided along the extension direction of the clamping arms 91.

[0057] See also Fig.13The shaping machine 10 includes a support base 101 and four telescopic driving members 102 respectively tilted above the four corners of the support base 101, and a shaping mold 103 is fixed to the telescopic end of the telescopic driving member 102. The fourth manipulator 13 grabs the metal mesh basket and covers it on the support base 101 with the opening facing downward. The shaping mold 103 is driven by the four telescopic driving members 102 to tilt down and punch the four bottom corners of the metal mesh basket, thereby shaping the bottom corners into rounded corners.

[0058] The fourth manipulator 13 and the fifth manipulator 15 both adopt magnetic grippers, which transfer by adsorbing the bottom surface of the metal basket.

[0059] In this embodiment, the workpiece output device 14 adopts a roller conveyor line.

[0060] The metal mesh basket production line of the present invention uses the first manipulator 5 to grab the metal mesh basket on the workpiece input positioning device 2 and transfer it to the welding positioning device 4. After the metal mesh basket is pressed and positioned by the welding positioning device 4, the first welding machine 3 welds the butt joint of the reinforcement frame 12 of the metal mesh basket. After welding is completed, the welding positioning device 4 releases the metal mesh basket so that the second manipulator 7 can transfer the metal mesh basket to the deburring punch 6. The deburring punch 6 removes the burrs generated by the welding of the first welding machine 3. The third manipulator 9 transfers the deburred metal mesh basket to the second welding machine 8. The second welding machine 8 welds the overlapping butt joint areas of the mesh at the four corners of the mesh container 11 of the metal mesh basket. The fourth manipulator 13 transfers the welded metal mesh basket to the shaping machine 10, and the shaping machine 10 shapes the bottom sharp corners of the metal mesh basket into rounded corners. The fifth manipulator 15 transfers the shaped metal mesh basket to the workpiece output device 14 for transportation to the next station for processing. In this way, multiple processing steps of the metal mesh basket can be carried out continuously, reducing manual operations and improving production efficiency.
