Problems solved by technology

This detection method has the following defects: the sampling inspection method has low sampling inspection rate, low accuracy of large-scale inspection, unqualified boards cannot be detected, and poor real-time performance; due to the huge number of batches of boards, the full inspection method has detection work The amount of labor is huge, the labor is very heavy, and it is difficult to match the large-scale overall automated production; whether it is random inspection or full inspection, manual inspection is greatly affected by experience and subjective factors, and there is an inevitable problem of detection errors, and manual The caliper used for detection can only detect the edge data of the board, but cannot detect the central area. There are inherent defects in the measurement principle, and it is easy to cause problems such as scratches on the surface of the board.

Embodiment 1

[0050] This embodiment is a method for detecting the warping deformation of the board, which is to transmit the board at a constant speed; during the uniform speed transmission of the board, the top detection component located above the board detects the distance between the board and the board in the height direction Change to get the degree of warpage of the plate; according to the degree of warpage to determine whether the warpage of the plate is qualified.

[0051] The method of the present invention can realize automatic detection of warpage and deformation of plates, save a lot of labor costs and improve detection efficiency, can effectively avoid the situation of subjective errors in manual detection, and improve detection accuracy; it can realize automatic full inspection of large batches of plates, It avoids the missed inspection of unqualified boards caused by random inspection, strengthens the processing consistency of subsequent processes and improves product qualit...

Embodiment 2

[0077] This embodiment is a device for detecting the warping deformation of boards. The difference from Embodiment 1 is that the top detection component includes a moving top distance measuring sensor module and a fixed top distance measuring sensor module, or only includes a movable top distance measuring sensor module. The moving top ranging sensing module does not include the stationary top ranging sensing module.

[0078] The movable top ranging sensing module is connected with the beam through the horizontal moving device, so as to realize the horizontal movement of the movable top ranging sensing module perpendicular to the conveying direction. The horizontal moving device can adopt existing technology, such as lead screw and nut mechanism, electric slide table and so on.

[0079] The control device is also used to set the width detection component before the top detection component according to the size of the board (the size of the board can be the size of the board ob...

Abstract

The invention provides a method for detecting plate piece warping deformation and equipment for realizing the method. The method comprises the steps that a plate piece is conveyed at a constant speed; In the constant-speed conveying process of the plate piece, a top detection assembly located above the plate piece obtains the plate piece warping deformation degree by detecting the distance change between the top detection assembly and the plate piece in the height direction; and whether the plate piece warping deformation is qualified or not is judged according to the warping deformation degree. By means of the method for detecting the plate piece warping deformation, warping deformation automatic detection on the plate piece can be realized, the labor cost is saved, the detection efficiency is improved, the detection precision is improved, the automatic full-detection work of large-batch plate pieces can be realized, the machining consistency and the product quality are improved, and the universality is high.

Description

technical field [0001] The invention relates to the technical field of customized furniture panel processing, and more specifically, relates to a method for detecting warping deformation of a panel and equipment for realizing the method. Background technique [0002] Under the general trend of "Industry 4.0", custom furniture manufacturers gradually eliminate inefficient manual production lines, and establish automatic panel production lines with CNC cutting processing centers, edge banding machines, and CNC drilling processing centers as core equipment. However, in Quality control still uses manual inspection, which does not match the highly automated production process. [0003] Various MDF parts commonly used in custom furniture, improper quenching and tempering or improper storage during the production process will cause uneven internal stress of the board. Warping and deformation of this kind of board after cutting is a common problem; warping and deformation are also ...
