Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment supporting components, in particular to a heat treatment crucible palletizing production line. Background Technique

[0002] Vacuum heat treatment is a new heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in vacuum heat treatment refers to an atmosphere environment below one atmosphere, including low vacuum, medium vacuum, high vacuum, and ultra-high vacuum. Vacuum heat treatment means that all or part of the heat treatment process is carried out in a vacuum state, greatly improving the heat treatment quality. Compared with conventional heat treatment, during vacuum heat treatment, oxidation-free, decarburization-free, and carburization-free can be achieved, the phosphorus chips on the surface of the workpiece can be removed, and degreasing and degassing can be carried out, etc., so as to achieve the effect of surface brightening and purification. Therefore, it is widely used. During heat treatment, materials are generally contained in crucibles.

[0003] The following drawbacks exist in the existing vacuum heat treatment operation process: The existing vacuum heat treatment process is generally manual. First, the crucible is placed on the conveyor belt, and after loading the materials, it is manually palletized. After palletizing, the forklift is controlled to send it into the vacuum heat treatment furnace. After the treatment is completed, it is taken out for manual depalletizing and material dumping. It is time-consuming and laborious, with a large labor intensity. At the same time, the dust generated during material pouring is also likely to affect the health of operators. For this reason, we propose a heat treatment crucible palletizing production line. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a heat treatment crucible palletizing production line. Through the robot component set on the surface of the conveyor belt and the special fixture, and using programming design for processing, automatic palletizing and depalletizing operations can be realized, effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The heat treatment crucible palletizing production line is sequentially provided with a vacuum furnace, an electric forklift, a material distributor, a bracket, a six-axis robot, a workbench, and a control console from the head end to the tail end. The vacuum furnace, the electric forklift, the material distributor, the bracket, the six-axis robot, and the workbench directly convey the crucible through a conveyor belt. The feeding end of the conveyor belt is provided with a vacuum furnace, and the discharging end of the conveyor belt is provided with a workbench. A clamp seat is installed at the power output end of the six-axis robot. The control console is communicatively connected to the six-axis robot and the electric forklift for controlling the actions of the six-axis robot and the electric forklift.

[0007] The heat treatment crucible palletizing production line further includes a partition frame, and the partition frame is located on one side close to the six-axis robot and the workbench.

[0008] Further, one end of the bottom of the clamping seat is fixedly connected with a fixed clamping plate. A guide rail is installed on the bottom surface of the clamping seat. The bottom of the clamping seat is movably connected with a movable clamping plate through the guide rail. Claw jaws are arranged at the bottoms of the fixed clamping plate and the movable clamping plate. When the six-axis robot operates, the power end drives the movement of the clamping seat. When the clamping seat clamps the crucible, it first moves to a position close to the crucible and descends to both sides of the crucible. Subsequently, the claw jaw on one side of the fixed clamping plate fits the surface of the crucible. The cylinder operates to drive the movable clamping plate to move along the guide rail until the claw jaws on the other side also clamp on the surface of the crucible, and then the clamping of the crucible can be completed, which is convenient for palletizing and depalletizing.

[0009] Further, a cylinder is installed on the lower surface of the clamping seat, and the cylinder is located between the fixed clamping plate and the guide rail. The power output end of the cylinder is connected to the surface of the movable clamping plate. The operation of the cylinder controls the movement of the movable clamping plate to clamp the crucible.

[0010] Further, limit plates for restricting the position of the crucible are integrally formed at the tops of the claw jaws. The limit plate structure can restrict the position of the clamping seat during the process of grasping the crucible and better fix the crucible at the same time.

[0011] Compared with the prior art, the utility model has the following beneficial effects: By controlling the operation console to preset the operation programs of the six-axis robot, electric forklift, conveyor belt and feeder, during the operation, the crucibles on the conveyor belt are filled with materials through the feeder, and then are conveyed to the position where they are automatically centered by the automatic centering module. The six-axis robot automatically grabs the crucibles and automatically stacks the crucibles on the top of the tray. The partition frame is filled with partitions. After stacking one layer of crucibles, the six-axis robot moves the partition to the first layer of the tray and continues to stack the crucibles to the preset height. After the stacking operation is completed, the electric forklift automatically forks the tray to the vacuum furnace. The vacuum furnace automatically opens, the electric forklift places the materials in the vacuum furnace, the electric forklift automatically exits, the vacuum furnace automatically closes and starts heating. After the heating is completed, the electric forklift moves the crucible to the workbench. The six-axis robot automatically un-stacks the crucibles stacked on the tray and grabs the crucibles above the workbench, turns over the crucibles and pours the materials onto the workbench to realize automatic discharging, reducing the amount of manual intervention, saving time and effort, and avoiding the harm of dust to the human body during the discharging operation; When the six-axis robot operates, the power end drives the movement of the clamping seat. When the clamping seat clamps the crucible, it first moves to a position close to the crucible and descends to both sides of the crucible. Subsequently, the claw jaw on one side of the fixed clamping plate fits the surface of the crucible. The cylinder operates to drive the movable clamping plate to move along the guide rail until the claw jaws on the other side also clamp on the surface of the crucible, and then the clamping of the crucible can be completed, which is convenient for palletizing and depalletizing.

The bottom of the clamping seat 11 is movably connected with a movable clamping plate 14 through the guide rail 13. Claw jaws 16 are arranged at the bottoms of the fixed clamping plate 12 and the movable clamping plate 14. When the six-axis robot 7 operates, the power end drives the movement of the clamping seat 11. When the clamping seat 11 clamps the crucible 10, it first moves to a position close to the crucible 10 and descends to both sides of the crucible 10. Subsequently, the claw jaw 16 on one side of the fixed clamping plate 12 fits the surface of the crucible 10. The cylinder 15 operates to drive the movable clamping plate 14 to move along the guide rail 13 until the claw jaw 16 on the other side also clamps on the surface of the crucible 10, and then the clamping of the crucible 10 can be completed, which is convenient for palletizing and depalletizing processing.
