Problems solved by technology

[0003] At present, many production fields need to monitor and measure the height of their products. For example, the pharmaceutical production line is used to monitor the height of the drug particles, and the electronic manufacturing field is used to monitor the solder paste and components during the processing of circuit boards (PCBA). Height measurement and monitoring. In the field of machining, it is used to measure the size of the workpiece. Due to the tiny precision devices, the height measurement accuracy is difficult to guarantee; therefore, it is very important to design and manufacture a monitoring device that can monitor the thickness of the product in real time.

Embodiment 1

[0028] In the electronics manufacturing industry, in the early stage of circuit board assembly, the height of the solder paste is measured from the solder paste coating process to realize early monitoring of the process quality:

[0029] An online thickness monitor, comprising a CCD industrial camera 1, a laser 2, a microprocessor 3 and an interface cable, the CCD industrial camera 1 and the laser 2 are respectively connected to the microprocessor 3 through an interface cable, and connected to the microprocessor device 3 for information interaction;

[0030] Described microprocessor 3 is also connected with driving motor 7, is used for controlling the rotating speed of driving motor 7;

[0031] The laser 2 and the CCD industrial camera 1 are respectively installed at an angle of 45° to the reference plane 4, the laser 2 emits a laser beam, the CCD industrial camera 1 captures the reflected beam, and the laser beam emitted by the laser 2 is reflected by the reference plane 4, ...

Embodiment 2

[0041] On the pharmaceutical production line, the height of the pills is monitored:

[0042] An online thickness monitor, comprising a CCD industrial camera 1, a laser 2, a microprocessor 3 and an interface cable, the CCD industrial camera 1 and the laser 2 are respectively connected to the microprocessor 3 through an interface cable, and connected to the microprocessor device 3 for information interaction;

[0043] Described microprocessor 3 is also connected with driving motor 7, is used for controlling the rotating speed of driving motor 7;

[0044] The CCD industrial camera 1 and the laser 2 are located on opposite sides;

[0045] Since the height of the pills is very small, adjust the inclined installation angles of the CCD industrial camera 1 and the laser 2 relative to the reference plane 4 to make it less than 45 degrees;

[0046] Transforming formula 1 to get:

[0047] l=h / cosθ (Formula 2)

[0048] Among them: h—the height of the medicine grain; l—the magnificatio...

Abstract

The invention discloses an online thickness monitor and an online thickness monitoring method. The online thickness monitor comprises a CCD industrial camera, laser, a microprocessor and an interface cable, wherein the CCD industrial camera and the laser are connected with the microprocessor through the interface cable and carry out information interaction with the microprocessor through the interface cable; the laser and the CCD industrial camera are installed on a reference plane at a certain inclined angle, the laser transmits a laser beam, the CCD industrial camera captures a reflected beam, the laser beam transmitted by the laser is reflected by the reference plane, and the reflected beam falls at the center of a view field of the CCD industrial camera; and the reference plane is a horizontal table used for placing a measured object. The online thickness monitor disclosed by the invention can carry out high-precision monitoring and measurement on the thickness of products, thereby being convenient for operators to master the thickness of the measured object visually and conveniently.

Description

technical field [0001] The invention relates to a monitoring instrument and a monitoring method, in particular to an online thickness monitoring instrument and an online thickness monitoring method. Background technique [0002] With the rapid development of the manufacturing industry, the requirements for manufacturing efficiency are also constantly increasing. In particular, modern manufacturing models such as intelligent manufacturing and flexible manufacturing require the industry to develop towards the goal of automation and intelligence. For large-scale mass production, not only maintain high requirements on the quality of end products, but also pay more attention to process quality, because early detection of product failure will reduce the cost of rework and repair, so the significance of early product quality control is even greater. [0003] At present, many production fields need to monitor and measure the height of their products. For example, the pharmaceutical ...
