Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a multi-station manipulator for a workshop production line. Background Art

[0002] Metal spraying has many important uses in product design. For example, spraying zinc and aluminum onto steel surfaces can obtain a protective coating to obtain corrosion resistance. Because metal spraying can spray metal onto almost any metal or non-metal surface, it provides a simple way to coat a conductive surface on a poor conductor or non-conductor surface.

[0003] The actual spraying structure of mechanical spraying is relatively fixed. The robot can only spray parts at one workstation and cannot process multiple groups of parts at the same time. During operation, the robot cannot conveniently adjust the spraying effect according to different objects. Both manual spraying and mechanical spraying are accustomed to performing trajectory spraying according to a specific method or procedure. Mechanical spraying has the problem of uneven spraying when spraying objects with different structures, resulting in poor actual spraying effect. Summary of the invention

The shifting mechanism shifts two groups of manipulators of different types according to processing requirements to meet the spraying and drying requirements of the workpiece. A corner structure is arranged inside the processing shell to switch the angles of the two groups of manipulators to repeatedly spray irregular workpieces and reduce dead angles in spraying.

[0006] Preferably, the shifting mechanism includes a control box, a driving motor, a plane gear, a spur gear, a cantilever and a guide slide rod. The guide slide rod is symmetrically arranged inside the control box. The outside of the guide slide rod is connected with a cantilever extending through it.

[0023] In this embodiment, the shifting mechanism 6 includes a control box 4, a driving motor 5, a plane gear 7, a spur gear 8, a cantilever 9 and a guide slide 10. The guide slide 10 is symmetrically arranged inside the control box 4. The cantilever 9 is connected to the outside of the guide slide 10. One side of the two groups of cantilevers 9 is connected to the spur gear 8. One side of the two groups of spur gears 8 is meshed with the plane gear 7.

[0029] Step 1: The operator first connects the primary robot arm 13 and the secondary robot arm 14 by bearings, and respectively connects the bottom end of the secondary robot arm 14 with the nozzle and the air injection pipe. During use, the workpiece is first placed directly on the top of the conveying base 3, and then multiple groups of workpieces are directly moved to the bottom of one group of secondary robot arms 14. Then, the surface of the workpiece is sprayed with a paint spray gun, and the two sides of the processing shell 1 are shielded with a shielding curtain 2 to prevent the sprayed paint or material mist from drifting out;

[0030] Step 2: The operator can stop the conveying base 3, use the driving motor 5 to drive the flat gear 7 to rotate, use the flat gear 7 to drive the spur gears 8 set on the left and right sides to move left and right, and use the guide slide bar 10 set on the outside to perform lateral guidance. The spur gear 8 drives the bottom end of the bearing base 11 to move laterally, and the first-level mechanical arm 13 and the second-level mechanical arm 14 are moved laterally through the bearing base 11, so as to control the spraying distance;
