Abstract

The utility model aims to provide a detector for detecting an impeller positioning guide rod of a through-flow fan impeller ultrasonic bonding machine. The detector for detecting the impeller positioning guide rod of the through-flow fan impeller ultrasonic bonding machine is used for high-precision and quick detection of the verticality of the impeller positioning guide rod of the through-flow fan impeller ultrasonic bonding machine, thereby improving welding quality. The detector for detecting the impeller positioning guide rod of the through-flow fan impeller ultrasonic bonding machine in the utility model includes a detection box. The key is that the detection box is provided with a CCD sensor and a laser emitter. The CCD sensor and the laser emitter are arranged at a certain angle, thereby enabling light beams emit to the to-be-detected guide rod from the laser emitter to reflect onto the CCD sensor. The CCD sensor and the laser emitter both connect with an industrial personal computer. The industrial personal computer receives data of the CCD sensor and controls the work of the CCD sensor and the laser emitter.

Description

A kind of through-flow fan impeller ultrasonic bonding machine impeller location guide detector
Technical field
The utility model belongs to the Automatic Measurement Technique field, specially refers to a kind of through-flow fan impeller ultrasonic bonding machine impeller location guide detector.
Background technology
The depth of parallelism of the impeller location guide verticality of through-flow fan impeller ultrasonic bonding machine and ultrasonic horn and impeller cushion cap is an important performance indexes that guarantees the blast fan welding quality.Ultrasonic bonding machine is in normal use; Because of influenced by hyperacoustic high-frequency vibration, board distortion etc.; Guide rod and soldering tip can be subjected to displacement or be out of shape; This displacement or distortion have directly influenced the quality of the through-flow fan impeller that is welded by the more piece impeller, like the concentricity of each joint impeller, welding strong degree etc.Therefore, ultrasonic bonder need detect and adjust after work a period of time the verticality of guide rod and the depth of parallelism of soldering tip.
Be to adopt Mechanical Contact formula dial gauge that the verticality of guide rod is measured detection at present, often need in the impulse stroke scope of guide rod, repeatedly drag table just can measure the side-play amount of guide rod verticality, detection speed be slower.Analyze from measuring principle, adopt dial gauge to drag table to measure and have unsurmountable measuring error, cause the uncertainty when guide rod adjusted.Because the dial gauge measurement is the one-dimensional measurement of a contact; We can't know the direction of guide rod skew in advance; It is in full accord to that is to say when placing dial gauge that its direction of measurement can't guarantee with the change in displacement direction of guide rod verticality, thereby the Abbe error that causes measuring can't accurately draw the actual shifts direction and the displacement of guide rod.In addition; In actual production; Use dial gauge to detect and adjust about tens minutes consuming time an of guide rod (every machine will detect at every turn, adjust two guide rods at least) and higher to testing staff's experience dependency degree, these all are adverse factors concerning the quality of production efficiency and product.The depth of parallelism of soldering tip detects and also has similar problem.
The utility model content
The purpose of the utility model is to propose a kind of through-flow fan impeller ultrasonic bonding machine impeller location guide detector, the verticality of through-flow fan impeller ultrasonic bonding machine impeller location guide being carried out high precision, to detect fast, and then improves welding quality.
The through-flow fan impeller ultrasonic bonding machine impeller location guide detector of the utility model comprises detection case; Key is to be provided with in the said detection case ccd sensor and generating laser; Said ccd sensor and generating laser form an angle and are provided with so that generating laser is mapped to the light of guide rod to be measured can reflex on the ccd sensor; Said ccd sensor all links to each other with an industrial computer with generating laser, and said industrial computer receives the data of ccd sensor and controls the work of said ccd sensor and generating laser.
The detection principle of the through-flow fan impeller ultrasonic bonding machine impeller location guide detector of the utility model is as shown in Figure 1; The displacement of guide rod and deformation can be resolved into x and two components of y on measurement face, have only and measure the actual displacement situation that x and y just can recognize guide rod simultaneously.This project adopts the method for laser non-contact measuring, and its principle is that the suitable angle of the emitted laser Shu Yiyi of generating laser institute incides the guide rod surface, and the hot spot of guide rod surface reflection is imaged on the area array CCD.If guide rod is subjected to displacement variation, the facula position that images on the area array CCD also can change.Design suitable optical imaging system and cooperate the software algorithm of optimizing, can measure the yardstick of the variation precision of facula position, just in micron-sized level at sub-pix.Instrument prototype experiment to build in the laboratory at present obtains data, and measuring accuracy has been enough to satisfy requirements of actual production about 10 microns.
Further, said detection case is installed on the ultrasonic bonder impeller cushion cap to be measured.Detector need be installed on the board of ultrasonic bonder easily, also requires board that one metastable witness mark face is provided simultaneously.Detector is installed on the cushion cap of impeller and with the cushion cap plane as the reference surface of measuring, ultrasonic bonder lifting screw drives impeller cushion cap moves up and down the squareness measurement that can accomplish guide rod.In general; Lower end of the guide rod is a stiff end and need not adjusting; When cushion cap moved on to the lower end, detector is measured lower end of the guide rod x, y positional value and is worth with this was reference value (zero point), and the x that measures when cushion cap moves on to the guide rod upper end, y positional value be the changing value of guide rod verticality just.The on-the-spot fixed screw that can adjust guide rod according to this measured value so repeats once can accomplish the adjustment of guide rod.
Further, said detection case is adsorbed on the ultrasonic bonder impeller cushion cap to be measured through magnet base, and is easy for installation, fixed.
Certainly; The depth of parallelism that above-mentioned detector also can be applicable to soldering tip detects; Only need one of development can make the rotating turntable of 360 degree, require its jitter error in the revolution range of 360 degree within 10 microns, detector be installed on the turntable and with the cushion cap plane as the reference surface of measuring; Measure the height value of the several select locations in soldering tip bottom, the depth of parallelism between soldering tip and cushion cap can be adjusted easily according to measured value in the scene.
The through-flow fan impeller ultrasonic bonding machine impeller location guide detector of the utility model is simple in structure, cost is low, automaticity is high, be suitable for the robotization testing of through-flow fan impeller ultrasonic bonding machine impeller location guide and soldering tip, can improve the efficient and the accuracy of detection greatly.
