Floating gripping mechanism

Abstract

The invention discloses a floating gripping mechanism. The floating gripping mechanism comprises a mounting plate, air grippers are arranged at two side edges of the mounting plate respectively, one of the air grippers is fixedly mounted at one side edge of the mounting plate, a floating device is arranged at the opposite side edge of the mounting plate and comprises linear guide rails fixedly mounted on the side edge portion of the mounting plate, an air gripper connecting plate is slidably arranged on the linear guide rails and is fixedly connected with the same-side air gripper, and limiting plates are vertically fixedly connected with the two ends of the air gripper connecting plate respectively. An elastic part is arranged between the limiting plates, a fixed sleeve fixedly mounted on the mounting plate sleeves the elastic part, press blocks sliding in a cavity are arranged at two ends of the elastic part in a butting manner, a contact rod extending out of a cover plate is fixedly arranged on each press block and butts against the corresponding limiting plate, or a contact part butts against each press block is arranged on the corresponding limiting plate. The floating gripping mechanism makes the distance between bodies of the air grippers adjustable in a floating manner.

Description

technical field [0001] The invention relates to the technical field of grabbing tooling, in particular to a floating grabbing mechanism. Background technique [0002] At present, when using SMT (Surface Mount Technology) automation equipment for surface mount operation of electronic products, after the SMT semi-finished product is tested, it is necessary to put the SMT semi-finished product into an anti-static turnover box, and automatically grab it through the grabbing mechanism. Turnaround use. Due to the high anti-static requirements of the SMT industry, in order to avoid the breakdown and damage of the components of the product due to the static electricity generated during the turnover process, the turnover boxes for SMT products are basically made manually to ensure the anti-static effect, but manual It is difficult to guarantee the consistency of the size of the turnover boxes produced, and there are more than one suppliers of the turnover boxes used in the same work...

AI Technical Summary

Problems solved by technology

[0003] a. The distance between the two jaws on both sides of the grasping mechanism on the existing SMT automation equipment is fixed, and cannot be adjusted in real time according to the length and size of the turnover box to be grasped;

[0004] b. Since the distance between the two jaws on both sides of the grasping mechanism on the existing SMT automation equipment is fixed, when grasping the turnover box with a large or small length, it depends on the turnover box If it is grasped by its own deformation, the failure rate of grasping is high, which frequently causes equipment alarms, requires manual processing, and affects the production capacity requirements of the workshop;

[0005] c. Refer to figure 1 , when grabbing the turnover box 3, there is a high probability that the jaws on both sides cannot be closed, and the magnetic switch on the jaw cylinder has no signal alarms frequently, which frequently causes equipment alarms and requires manual processing, which affects the production capacity of the workshop.
