Description

Visual system uniform velocity automatic feeding device is swept to line
Technical Field
The invention relates to the field of industrial automatic production and detection, such as the industries of electronic manufacturing, automobile manufacturing, packaging, printing, processing machinery and the like, in particular to a constant-speed automatic feeding device of a linear scanning vision system.
Background
Machine vision has been used in various industries for manufacturing and quality inspection for many years, and the machine vision can improve inspection accuracy or accelerate production speed, so that the technology has gradually become a necessary ring for many production inspection devices. At present, most of image detection systems in the market adopt an Area-scan (Area-scan) method, but as the size of products (such as LCD panels) increases, the requirements for improving productivity and precision continuously increase, and the resolution and image capturing speed of the Area scan camera cannot meet the requirements. In order to solve these problems, a Line-scan camera (Line-scan) has been developed, and is a preferred solution for detecting workpieces with high speed, high precision and large size. Whether checking the corners of the image or evaluating surface degradation, a line scan camera is an excellent choice for surface quality detection. However, the line scan inspection system is very suitable for inspecting a continuous material, but it must use the moving speed to acquire an image, which is completely different from the principle that the plane scan inspection system can acquire an image by only a simple exposure. Therefore, for the line scanning system, the obtained high quality image is not only related to the visual sense device, but also requires a uniform and stable moving speed.
In current automated manufacturing lines, conveyor belts or rollers are the most common way to convey workpieces. The transmission mode adopts open-loop control, the transmission mechanism is easy to assemble, the structure is simple, the price is low, and the application is the most extensive. But the outstanding limitation is that the speed is difficult to control when the transmission is used for conveying. Particularly, when two or more conveyor belts are conveyed together, the belt slips and slacks. If the conveyor belt is directly used as a feeding system of the line scanning camera, the speed fluctuation phenomenon exists. Since the linear scanning imaging is closely related to the transmission speed of the workpiece, the speed disturbance can cause the size of the image to be short and long, and the uniform imaging effect is difficult to form. If the feeding mechanism is controlled by a closed-loop servo completely, the conveying range of the feeding mechanism is far lower than that of the conveying belt, and the cost price is very high. Therefore, how to realize a stable and reliable uniform-speed automatic feeding device suitable for a linear scanning vision system is very important for improving the imaging quality and the measurement precision of the linear scanning vision system and further improving the automation degree of the whole system.

In this embodiment, the pushing block 32 is a wedge shape with a narrow front end and a wide rear end.
The present embodiment further includes a third infrared sensor 5, where the third infrared sensor 5 is disposed at a tail end of the pushing mechanism to control the opening of the next detection process.
The present embodiment is described in more detail below:
the invention adopts a two-stage transmission scheme of half opening and half closing, and is divided into two strokes of an open-loop transmission stage and a closed-loop pushing stage. In the conveying stage of feeding, the open-loop conveying belt is adopted for conveying, the integration with the existing conveying belt mechanism is facilitated, the system is convenient to transplant, and in the pushing stage of feeding, the closed-loop servo motor is adopted for controlling, so that the constant speed stability of the conveying speed of the workpiece is ensured. And a clamping mechanism carrying a driving wheel and an auxiliary wheel is adopted for transition between the two conveying modes, so that the smooth transition of the two movements is ensured.
In order to ensure that the fed workpiece is tightly combined with the closed-loop transmission mechanism and the workpiece is smoothly transited from the conveyor belt 1 to the servo pushing mechanism, a pneumatic mechanism is adopted to clamp the workpiece, and the auxiliary rubber wheels (a driving wheel, a driven wheel and a guide wheel) are used for driving the workpiece to the pushing mechanism. The pneumatic mechanism is composed of a cylinder perpendicular to the moving direction of the workpiece, auxiliary wheels are made of hard rubber, and the action of the driving wheel is controlled by a motor.
Two driven wheels 24 are arranged at the positions 1cm away from the two sides of the driving wheel 23, the driving wheel 23 is about 1mm higher than the driven wheels 24, and when the PLC sends an air cylinder clamping action instruction, the pneumatic mechanism carries the driving wheel and the driven wheels to clamp a workpiece, so that the workpiece is horizontal to the pushing guide rail. Because the driving wheel and the driven wheel are both made of rubber materials and have certain elasticity, when the clamping action is finished, the driving wheel and the driven wheel can be tightly attached to a workpiece, and the driving wheel is slightly higher than the driven wheel, so that the driving wheel can be more tightly attached. When the clamping action occurs, the driving wheel motor starts to rotate, and the workpiece is driven to be separated from the conveying belt by friction and enters a candidate position of the servo pushing mechanism. The driving wheel is used for guiding the workpiece to move from the belt mechanism to the position to be pushed of the servo pushing mechanism in a flexible mode, and the auxiliary wheel is used for ensuring that the workpiece cannot incline when the driving wheel drives the workpiece to move and keeping the workpiece and the pushing mechanism horizontal.
The transmission of the feeding mechanism has various transition modes, and the feeding mechanism can incline in the processes of feeding, pushing and the like, so that the embodiment is provided with a guide and correction mechanism for aligning the feeding mechanism.
1) Two groups of steel spring pieces 11 are respectively added at the side of the open-loop conveyor belt 1 to serve as guiding devices, so that the workpiece is prevented from being separated from the conveyor belt 1, and after the conveyor belt 1 conveys the workpiece to be separated from the conveyor belt 1 to be static, the workpiece is pushed by a cylinder 21 of a transition mechanism to be clamped close to the inner side, so that the workpiece is kept to be in a horizontal position with the inner side of a pushing mechanism.
2) The correcting device is mainly used for preventing the workpiece 100 from being pushed and deflected by the pushing mechanism in the closed-loop servo process. Considering that when the pushing mechanism pushes the workpiece at a constant speed, the inner side of the pushing mechanism is close to the inner wall 4, and the inner side of the pushing mechanism is always deviated to the outer side when deviating from the track, a plurality of iron guide strips 34 are added at a plurality of positions in the pushing process as correction devices, and the iron guide strips are placed at an angle of 30 degrees with the moving direction of the workpiece. The number of the guide bars 34 is related to the length of the servo track and the size and length of the end face of the workpiece, and can be added at any time according to needs.
3) Before entering the vision system, namely the tail end position of the pushing mechanism, a spring correcting mechanism, namely a fluctuation correcting bullet 35 is added to ensure that the final direction of the workpiece is vertical to the linear scanning direction and the workpiece enters the linear scanning system at a constant speed.
The material of the pushing block at the front end of the pushing mechanism of the embodiment is black rubber, and the shape of the pushing block is wedge-shaped. The rubber material is used for weakening the vibration and impact between the front end of the pushing mechanism and a workpiece in the pushing process, so that the front end of the pushing mechanism is tightly attached to the workpiece, the black color is used for ensuring that the pushing mechanism is easy to pull out by using an image processing method after entering a linear scanning vision system, and the wedge-shaped shape (the front end is shorter and the rear end is wider) is convenient to be matched with a feeding correction mechanism of the device and is used for gradually guiding the workpiece to linear scanning detection.
In the embodiment, the digital infrared sensor is selected as a device for transmission switching and workpiece position sensing. The PLC controller is selected as a core device for planning the action of the mechanism, the signal processing of all sensors, the action of the air cylinder and the servo control of the motor are completed by the PLC control, and the whole system does not need other embedded controllers or a PC industrial personal computer and only needs the PLC.
1) Arrangement of sensors
In order to facilitate the device to change actions and switch transmission at a designated station, sensors need to be arranged at reasonable positions and combined with control instructions of a PLC (programmable logic controller) to realize the coordination and consistency of the actions. According to the design of the transmission mode of the feeding mechanism, the layout of the sensors is as follows:
a first infrared sensor 12 is arranged at the initial position of the material conveying conveyor belt 1 and used for judging whether feeding is carried out or not, and the arrangement mode is that the sensor is perpendicular to the conveying direction of workpieces. And a second infrared sensor 13 is arranged at the tail end of the material conveying conveyor belt 1 and used for judging whether the conveying is finished or not. The placement is such that the sensor is at a 45 degree angle to the workpiece transport direction.
And a third infrared sensor 5 is arranged at the tail end of the pushing mechanism and used for judging whether pushing is finished or not and starting the linear scanning visual detection system. The placement is such that the sensor is perpendicular to the workpiece transport direction.

A. whether work piece supplied materials is judged at fortune material conveyer belt initial position to first infrared sensor 12, and PLC judges whether there is the work piece to get into according to digital signal high-low level, and when judging that there is the work piece to get into, PLC sends the motion instruction for conveyer belt, carries the work piece motion.
B. When the workpiece 100 is conveyed from the conveyor belt 1 to the second infrared sensor 13 at the end position of the conveyor belt under the guidance of the guide mechanism, it is determined whether the conveyance of the incoming material is completed. And when the incoming material is determined to be conveyed, the PLC stops the movement of the conveyor belt, and opens the air cylinder of the pneumatic abutting and flexible transition mechanism to clamp the workpiece.
C. After the transition mechanism clamps the workpiece, the PLC drives a motor of a driving wheel 23 in the pneumatic mechanism to drive the workpiece to be separated from the conveying belt, the workpiece is guided to a position to be pushed of the servo mechanism by a driven wheel, and after the workpiece reaches a target place, the motor of the driving wheel stops rotating, and the transition mechanism resets.
D. When the workpiece is positioned at the position to be pushed by the pushing mechanism, the PLC controls the pushing servo motor to drive the pushing block 32 to contact with the workpiece, the workpiece is kept pushed along the pushing plane at a constant speed under the guidance of the correcting mechanism, when the third infrared sensor 5 at the tail end of the pushing mechanism detects that the workpiece is pushed to the visual detection position, visual system equipment such as a light source and a camera is started, and the pushing mechanism is reset to the initial state to prepare for next pushing.
The invention has the following remarkable characteristics:
1. the semi-open and semi-closed two-stage transmission scheme is used for automatic feeding of a line scanning vision system, the defect of unstable transmission speed of a traditional belt is overcome, and a hardware basis is provided for reliable line scanning imaging.
