Full-feedback cap screwing mechanism and cap screwing method thereof

Abstract

The invention discloses a full-feedback cap screwing mechanism, comprising a mechanism bracket as well as a drive mechanism, a displacement detection unit, a cap screwing friction plate and a transmission mechanism which are arranged on the mechanism bracket; wherein the displacement detection unit is connected with the cap screwing friction plate so as to detect the position of a screw thread; the drive mechanism is connected with the cap screwing friction plate through the transmission mechanism and drives the cap screwing friction plate to rotate forwards or backwards. The invention furtherdiscloses a cap screwing method based on the full-feedback cap screwing mechanism; the drive mechanism reverses firstly and drives the cap screwing friction plate to reverse, the displacement detection unit monitors the position of the screw thread in the whole process while the cap screwing friction plate reverses, and when the screw thread of a bottle cap and a bottle opening is detected to correspond, the drive mechanism rotates forwards, drives the cap screwing friction plate to rotate forwards, and then screws the bottle cap and the bottle opening. The full-feedback cap screwing mechanism and the cap screwing method provided by the invention solve the problem that the bottle opening and the bottle cap are not matched and damaged in the screwing process, and further ensure the cap screwing quality.

Description

technical field [0001] The invention relates to a full-feedback cap screwing mechanism and a cap screwing method. Background technique [0002] The traditional capping method is to manually match the internal thread of the bottle cap with the external thread of the bottle mouth and screw it to the bottle body. In this way, for the mass production of enterprises, it is not only labor-intensive, but also low in efficiency and poor in product consistency. . In the prior art, capping equipment has been used instead of labor, but most of the capping technologies in the prior art use a manipulator to grab the bottle cap, then move the cap to the position above the bottle mouth of the bottle, and then control the manipulator to move downward again. After rotating in one direction, it is tightened with the bottle mouth, but this technology has defects: once the robot grabs the bottle cap and tightens it with a position error on the bottle mouth, it is easy to damage the bottle cap ...

[0002] The traditional capping method is to manually match the internal thread of the bottle cap with the external thread of the bottle mouth and screw it to the bottle body. In this way, for the mass production of enterprises, it is not only labor-intensive, but also low in efficiency and poor in product consistency.

In the prior art, capping equipment has been used instead of labor, but most of the capping technologies in the prior art use a manipulator to grab the bottle cap, then move the cap to the position above the bottle mouth of the bottle, and then control the manipulator to move downward again. After rotating in one direction, it is tightened with the bottle mouth, but this technology has defects: once the robot grabs the bottle cap and tightens it with a position error on the bottle mouth, it is easy to damage the bottle cap and the bottle mouth, and the quality of the screw cap cannot be guaranteed.
