Abstract
The invention discloses a device and method for detecting the welding quality of a storage battery busbar. The device comprises a detection kiln, a conveyor belt and a thermal imager, wherein an ultrasonic generator located above the conveyor belt is arranged in the detection kiln and the thermal imager is fixed at the exterior of the back end of the detection kiln according to the conveying direction of the conveyor belt. The invention provides a detection device and method for detecting whether the welding of a polar plate and a polar lug on the storage battery busbar is qualified or not; and by means of the detection method and device, the detection speed is rapid and the accuracy is high, the original structure of the storage battery busbar needs not to be destroyed and mass detection can be carried out with veteran surveyor as before.
Description
Technical field:
The present invention relates to the lead accumulator technical field, relate to a kind of pick-up unit and detection method of checking accumulator bus-bar welding quality in particular.
Background technology:
Whether the welding of back pole plate of the bus-bar of lead-acid battery welding at present and lug is qualified, there are not effective detection means and method, generally all be that the checker rule of thumb judges, but the result of Pan Duaning is very inaccurate like this, rely on self experience of checker fully, and the limited amount that the checker can check in a day, wanting a large amount of production just needs the new checker of training, need long time and train new checker, also need a large amount of fund inputs.If think to know accurately whether the pole plate of accumulator bus-bar and the welding between the lug be qualified, the method that can only adopt the laboratory to detect, the laboratory determination check is undertaken by cutting this destructive test of bus-bar open, but such destructive test is not suitable for detecting on the production line, can only adopt under specific situation; Therefore on-line monitoring can only be to estimate by rule of thumb on production line.And the laboratory determination check is destructive can not the reparation, can only be indirect, unilateral detection to the quality at line products therefore.
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art part, whether qualified a kind of welding of accumulator bus-bar top crown and lug pick-up unit and detection method checked be provided, this detection method is fast with the device detection speed, accuracy rate is high, do not need to destroy the original structure of accumulator bus-bar yet, can also large batch of testing, do not need will use veteran checker like that in the past yet.
Technology solution of the present invention is as follows:
The device of check accumulator bus-bar welding quality, comprise and detect kiln and travelling belt, one ultrasonic generator that is positioned at described travelling belt top is arranged in the described detection kiln, also comprise a thermal imaging system, it looks up to be fixed on according to the travelling belt sender and detects outside, kiln rear end.
The device of described check accumulator bus-bar welding quality, described ultrasonic generator is the ultrasonic generator of frequency adjustable.
The device of described check accumulator bus-bar welding quality, described be installed in detect ultrasonic generator in the kiln be positioned at travelling belt directly over.
The method of check accumulator bus-bar welding quality,
(1) the semi-manufacture accumulator that will finish bus-bar welding is placed on the travelling belt that detects kiln;
(2) by travelling belt described semi-manufacture accumulator is carried in the past backward;
(3) ultrasonic generator has probe to stretch out the bus-bar of contact battery, sends ultrasound wave simultaneously, and the semi-manufacture accumulator is shaken;
(4) carry out imaging by thermal imaging system detecting the kiln rear end, carry out imaging according to the difference of thermal value after, can judge whether the quality of weld qualified.
Beneficial effect of the present invention is:
The pick-up unit of check accumulator bus-bar welding quality of the present invention, it is simple in structure, easy to operate, provides a kind of and can not destroy accumulator structure, testing result pick-up unit accurately for accumulator bus-bar lug and pole plate welding quality detect; Its detection method is to utilize ultrasonic generator and mistake thermal imaging system to detect in addition, has replaced the method that relies on manual detection, and this detection method is very simple, does not also destroy detected accumulator structure, and detection speed is very fast, the accuracy rate height.Compare detection mode in the past, utilize this pick-up unit or detection method, whether the structure that can not destroy product just can detect accurately qualified, so just saved and needed veteran overlooker in the past, only need the ordinary person to train a little and can be competent at, and once can detect a plurality of products, detection speed has the raising of matter.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Embodiment:
The following stated is preferred embodiment of the present invention only, is not that the scope of the invention is limited.
Embodiment sees accompanying drawing 1; The device of check accumulator bus-bar welding quality, comprise and detect kiln 1 and travelling belt 2, driving-belt 2 runs through whole detection kiln and is fixed on the detection kiln, and the both ends of detecting kiln are stretched out at two ends, detect kiln 1 and be " protruding " font, driving-belt can known raceway, travelling belt etc.; One ultrasonic generator 3 that is positioned at described travelling belt top is arranged in the described detection kiln 1, described ultrasonic generator is fixed on the top of detecting kiln, the teat that both was " protruding " font also comprises a thermal imaging system 4, and it looks up to be fixed on according to the travelling belt sender and detects outside, kiln 1 rear end.Ultrasonic generator has probe to stretch out the bus-bar of contact battery, sends ultrasound wave simultaneously to carrying the semi-finished product cell battery 5 of coming to vibrate from travelling belt.
Described ultrasonic generator is the ultrasonic generator of frequency adjustable.Power is from " 0 "～3000 watt adjustable power, and frequency is from the adjustable ultrasonic generator of 20HKZ～40KHZ.
Described be installed in detect ultrasonic generator in the kiln be positioned at travelling belt directly over.
When detecting, the semi-manufacture accumulator 5 of finishing the bus-bar welding is placed on the travelling belt 2 that detects kiln, by travelling belt 2 backward conveying in the past, can once place a plurality ofly in the time of placement, can accelerate detection speed like this, increase work efficiency; In the 5 process ultrasonic generators of the semi-manufacture accumulator on travelling belt, ultrasonic generator sends ultrasound wave, and the semi-manufacture accumulator is shaken; The bus-bar top crown of semi-manufacture accumulator and the weld of lug can generate heat because of vibrations, the part thermal value of failure welding will be higher than other positions, if welding is good, then thermal value can not be higher than other parts, like this by being arranged on when detecting the kiln rear end, by thermal imaging system it is carried out imaging, carry out imaging processing, can judge just according to thermal value whether the quality of weld is qualified according to the difference of thermal value.And thermal imaging system is arranged on the outside, observes very convenient.On the detection kiln, can also be provided with alarm in addition, thermal imaging system is connected with alarm, when detection is underproof, allow alarm send the sound/light of warning, remind the operator, so not needing always the someone to keep on the limit of pick-up unit stares at, can a workman be responsible for a plurality of pick-up units, increase work efficiency, reduce cost of labor.
