Description

Device for simultaneously detecting flatness of two sides of frame for rectangular frame corner connector automatic assembly machine
Technical Field
The utility model belongs to the field of nonstandard automatic machinery, and relates to an automatic detection device for rectangular frame corner code assembly, in particular to a simultaneous detection device for the flatness of two sides of a frame for an automatic rectangular frame corner code assembly machine.
Background
With the gradual disappearance of "population bonus", the trend of replacing manual work with non-standard automated machinery is becoming remarkable. Among them, in the assembly of various rectangular frames such as doors and windows, solar panel trays, billboards, etc., various customized non-standard automated assembly machines are presented. In these rectangular rims, the connection between the rims is achieved by connecting the corner brackets. In the automated assembly of rectangular frames, the use of cylinders to press the connecting corner brackets into the two ends of the rectangular frame is an indispensable process, but most of such frames are elongated bars (fig. 1), and the two ends of the frame are easily deformed by compression during the installation of the corner brackets. Whether the frame is straight or not will directly affect the quality of the whole rectangular frame.
Methods for detecting flatness generally fall into two categories, contact and non-contact. The utility model patent with application number 201510936126.4 discloses a plate flatness detector, wherein a detection device main body of the detector is a detection wheel, the detector rolls on a detected plane by virtue of the detection wheel, and the up-and-down fluctuation of the detected plane detected in the rolling process is converted into analog quantity by a sensor and then displayed on a display screen. The utility model patent with application number 201720300794.2 discloses an automatic production system of aluminum alloy frames, wherein a frame detection device mainly comprises a laser scanning sensor and control equipment, the laser scanning sensor can scan a detection surface, and acquired information is transmitted to the control equipment for analysis and processing.

In fact, for a rectangular frame assembled with corner codes, the integral bending deformation caused by the compression of two ends is a main cause of unqualified products, and the sensor can judge whether the frame is deformed or not only by detecting sampling points at fixed positions at partial positions of the frame. Meanwhile, the rectangular frame after the corner connector is assembled needs to detect the flatness in at least two directions, and at present, whether contact type or non-contact type is adopted in multiple steps, namely, one surface is detected, and the other surface is detected after the detection is finished. In view of the fact that the rectangular frame is extremely large in use amount, step detection is low in productivity and labor intensity of workers is extremely high.
