DETAILED DESCRIPTION

[0038] In order to deepen the understanding of the utility model, the utility model will be further described in detail below with reference to implementation cases and drawings. The utility model can be implemented in the following ways:

[0039] Example 1

[0040] Reference Figure 1-5 The automated welding and polishing production line comprises a welding mechanism 1, a polishing mechanism 2 and a feeding device 3. The feeding device 3 is connected between the welding mechanism 1 and the polishing mechanism 2 and is used to transport the welded workpiece 4 to the polishing mechanism 2.

[0041] Wherein, the welding mechanism 1 includes a welding rotary table 11 and a welding manipulator 12 arranged on the side of the welding rotary table. The welding rotary table 11 includes a horizontal tooling plate 111, a horizontal base 112 and a rotary drive assembly 113. The horizontal tooling plate 111 is provided with a plurality of welding fixtures 114 for fixing the workpiece 4, and the welding fixtures 114 include a product bottom plate 115, and the product bottom plate 115 is provided with a plurality of quick clamps 116 and a fixed bracket 117 for fixing the workpiece 4. The principle of fixing the workpiece 4 by using the quick clamps 116 and the fixed bracket 117 when the workpiece is fixed by manual or cylinder opening and closing is a conventional technical means in the art, which will not be elaborated here. In this embodiment, two welding fixtures 114 are provided, and each welding fixture 114 can fix two workpieces 4. A light shielding plate 118 is provided between the two welding fixtures 114, which can effectively prevent the tin from splashing onto other workpieces 4 of another welding fixture 114 during the welding process. The horizontal base 112 is arranged below the horizontal tooling disk 111; the rotation drive assembly 113 is located between the horizontal tooling disk 111 and the horizontal base 112, and is used to drive the horizontal tooling disk 111 to rotate above the horizontal base 112. The rotation drive assembly 113 includes an inner tooth, an outer ring, and a driving source for driving the inner tooth to rotate. The driving source can be a motor, and the driving source drives the inner tooth and the outer ring to rotate, thereby driving the horizontal tooling disk 111 to rotate.

[0042] The welding robot 12 includes a robot arm 121, a welding gun 122 and a wire feeder assembly 123. The welding gun 122 is arranged at the end of the robot arm 121; the wire feeder assembly 123 is arranged on the robot arm 121. The robot arm 121 includes a waist 1211, an upper arm 1212, an elbow 1213, a small arm assembly 1214 and a wrist assembly 1215 which are movably connected in sequence. A fixed base 124 is arranged at the bottom of the robot arm 121, and the waist 1211 of the robot arm 121 is connected to the fixed base 124. Specifically, the welding gun 122 shown is connected to the wrist assembly 1215, and the wire feeder assembly 123 is arranged behind the elbow 1213. The wire feeder assembly 123 delivers the welding wire on the wire reel assembly 125 to the welding gun 122, and the robot arm 121 controls the welding gun 122 to weld the workpiece 4.

[0043] A safety net 13 is arranged around the welding mechanism 1. Since welding is dangerous, the design of the safety net 13 defines a safe area for welding operations, greatly improving the safety performance of the production line.

[0044] The grinding mechanism 2 includes a grinding rotating table 21 and a grinding manipulator 22 located on a frame. The grinding rotating table 21 includes a grinding turntable 211. The grinding turntable 211 is provided with a plurality of grinding fixtures 212. A dust baffle 213 is provided in the radial direction of the grinding turntable 211. The bottom of the grinding turntable 211 is provided with a grinding rotation driving source (not shown in the figure) for driving the grinding turntable 211 to rotate. The grinding rotation driving source can be a motor. In this embodiment, four grinding fixtures 212 are provided, and two are provided on each side of the dust baffle 213. When the workpiece 4 on one side of the dust baffle 213 is polished, the grinding rotation driving source will drive the grinding turntable 211 to rotate 180°, so that the unpolished workpiece 4 rotates to the side close to the grinding manipulator 22. A strong grinder 23 is arranged above the grinding rotary workbench 21 , and a driving source for driving a grinding head to move up and down to grind the workpiece 4 is arranged on the strong grinder 23 , and the driving source may be a motor.

[0045] The grinding mechanism 2 is provided with a dustproof enclosure 24 on the periphery, forming a relatively closed grinding area, which can effectively prevent dust from polluting the working environment outside the grinding area. A warning light 25 is provided on the top of the dustproof enclosure 24. The warning light 25 used in this embodiment is a three-color warning light. When the processing equipment inside the grinding mechanism 2 fails or exceeds the set safety parameters, the warning light 25 can flash, change color, etc. to remind the staff to take corresponding measures in time to avoid accidents.

[0046] The feeding device 3 includes a manipulator 31 and an adjustable clamp 32 arranged at the end of the manipulator 31. The manipulator 31 clamps the welded workpiece 4 on the welding rotary table 11 with the adjustable clamp 32, and transports the welded workpiece 4 to the grinding rotary table 21 of the grinding mechanism 2 for grinding.

[0047] Example 2

[0048] The welding mechanism 1 and the grinding mechanism 2 of the present embodiment 2 are the same as those of the embodiment 1, except that the feeding device 3 comprises a conveyor belt 33, a manipulator 31 disposed at both ends of the conveyor belt 33, and an adjustable clamp 32 disposed at the end of the manipulator 31. The manipulator 31 close to the welding mechanism 1 clamps the welded workpiece 4 on the welding rotary table 11 with the adjustable clamp 32, and puts the welded workpiece 4 on the conveyor belt 33. When the workpiece 4 on the conveyor belt 33 runs to the grinding mechanism 2, the manipulator 31 close to the grinding mechanism 2 clamps the workpiece 4 with the adjustable clamp 32 and conveys it to the grinding rotary table 21 of the grinding mechanism 2 for grinding.

[0049] Working principle of the utility model: the workpiece 4 to be welded is placed on the horizontal tooling disk 111 of the welding rotary table 11 by a feeding device or manually, and the workpiece 4 is fixed by a welding fixture 114. The wire feeder assembly 123 on the welding manipulator 12 delivers the welding wire to the welding gun 122, and the robot arm 121 controls the welding gun 122 to weld the workpiece 4 according to a pre-set program. After the workpiece 4 on the side close to the welding manipulator 12 is welded, the quick clamp 116 releases the workpiece, and the driving source of the rotary drive assembly 113 drives the inner teeth and the outer ring to rotate, thereby driving the horizontal tooling disk 111 to rotate, so that the workpiece 4 to be welded on the other side is rotated to the side close to the welding manipulator 12 for welding. At the same time, the feeding device 3 delivers the previously welded workpiece 4 to the grinding mechanism 2. The grinding rotary drive source rotates the unpolished workpiece 4 on the grinding turntable 211 to the side close to the grinding manipulator 22 for grinding. When the grinding manipulator 22 and the strong grinder 23 finish grinding the workpiece 4, the grinding rotary drive source drives the grinding turntable 211 to rotate 180°, so that the unpolished workpiece 4 rotates to the side close to the grinding manipulator 22 for grinding. At the same time, the workpiece 4 that has completed the grinding process is unloaded by the unloading device or manually for stacking or transfer to the next station.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
