End effector of taking and placing mechanical arm for heat-forming box type furnace

Abstract

The invention discloses an end effector of a taking and placing mechanical arm for heat-forming box type furnace. The end effector comprises an end effector frame, side-by-side rods which are assembled in the frame, material sheet clamping assemblies which are assembled on the side-by-side rods and clamping assembly movement driving mechanisms which are assembled on the frame, wherein each clamping assembly comprises a support, an upper clamping jaw fixed on the corresponding support, a lower clamping jaw hinged to the corresponding support, a lower clamping jaw return spring, a pull wire pinconnected with a corresponding pull wire and the corresponding lower clamping jaw, and each clamping assembly movement driving mechanism comprises an air cylinder fixed on the frame and a pull wire connected with the corresponding air cylinder and the corresponding clamping assembly. The end effector has the positive effects that compared with the prior art, the operation is flexible, material sheets are clamped firmly, the throwing positions and the picking positions of the material sheets are accurate and rapid, the material sheets are grabbed from the positions above the material sheets, the height of a furnace chamber of the heating furnace can be reduced, the distance between an electric heating wire and a plate blank can be reduced, the heat dissipation utilization rate of an electric heating element is high, and electric energy is saved; the material sheet transferring speed is increased, the material sheet heat loss is small, the temperature of the material sheets between the heating furnace and a mold are easy to control, and product forming is facilitated.

Description

technical field [0001] The invention belongs to the field of operating machinery and equipment, and in particular relates to a pick-and-place manipulator. Background technique [0002] In the prior art, the end picker of the thermoforming box furnace generally adopts a fence-type bracket in the process of robot operation. The end picker is installed at the end of the mechanical arm, and there is no mechanical linkage mechanism in the end picker. During the discharging operation, the manipulator extends the end picker into the thermoforming box furnace, and inserts the front gate of the end picker into the gap between the furnace bricks of the box furnace until a certain depth is reached. Put it on the hearth brick. The manipulator is pulled out from the gap of the furnace brick under the sheet. During the reclaiming operation, the manipulator passes through the gap between the furnace bricks under the sheet and reaches the fixed position under the blank, then the manipula...

AI Technical Summary

Problems solved by technology

[0003] 1. When designing the heating furnace, the height of the furnace brick should be considered to cooperate with the manipulator end picker, so the height is often designed relatively high, resulting in too large distance between the sheet material and the heating resistance wire, too long heating time, and high energy consumption

[0004] 2. After the manipulator picks up the material, it needs to be transferred to another feeding manipulator. The transfer time + feeding time is relatively long, and the temperature loss of the material sheet is large, which has an impact on hot stamping.

[0005] 3. Inaccurate loading and unloading positions will lead to different clamping positions of the loading manipulator each time, and then different positions in the hot stamping mold, which will affect the hot stamping forming effect and easily produce defective products
