Abstract
The invention discloses a storage battery butt welding machine monitoring device, and relates to the technical field of metal welding device manufacturing. The storage battery butt welding machine monitoring device comprises a butt welding machine, a current sensor is arranged in a welding return circuit of the butt welding machine, an output end of the current sensor is connected with an input end of an alarm controller, and an input signal changing circuit, a voltage comparator and an alarm output unit are arranged in the alarm controller. The voltage comparator is a double-threshold voltage comparator, and the alarm output unit is an audible and visual alarm. Compared with the prior art, the storage battery butt welding machine monitoring device can solve the problems that low product percent of pass and high production cost are caused by the fact that a real-time monitoring device is not provided for welding currents in a butt welding machine.
Description
Technical field
The present invention relates to metal solder equipment manufacturing technology field, especially a kind of battery butt welding machine.
Background technology
Along with the tremendous influence that energy-conservation and cry environmental protection day by day improve and global financial crisis produces sale of automobile, hybrid electric vehicle will become the main product on automobile market.The market share of hybrid electric vehicle is increasing gradually.Hybrid electrically vehicle electric pond is the newly-increased great market of battery industry.Lead-acid accumulator is used for hybrid electric vehicle and pure electric vehicle has great advantage, its have cheap, monomer voltage stable, the security performance advantages of higher.Lead-acid accumulator has many production links, and butt welding operation wherein is to use butt welding machine that the series welding to welding column of several cells is connected into one reaching the operation of rated voltage, and this operation is very crucial operation together in lead-acid accumulator production process.At present the butt welding machine that uses of my company often occur welding current exceed setting range and damage cell to welding column, even jeopardize the phenomenon of product quality, because this equipment does not have the welding current real-time monitoring device, when the generation welding current exceeds the situation of setting range, the operator is difficult in time find, to such an extent as to often cause a series of defective work, have a strong impact on production cost.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can carry out to battery butt welding machine welding current the battery butt welding machine monitoring device of Real-Time Monitoring and overload alarm.
In order to address the above problem, the technical solution used in the present invention is: this battery butt welding machine monitoring device, include butt welding machine, be provided with current sensor in the welding circuit of described butt welding machine, the output of described current sensor is connected with the input of alarm controller, is provided with input signal translation circuit, voltage comparator and warning output unit in described alarm controller.
In above-mentioned battery butt welding machine monitoring device technical scheme, technical scheme can also be more specifically: described voltage comparator is the double threshold voltage comparator.
Further: described warning output unit is audible-visual annunciator.
Owing to having adopted such scheme, the present invention compared with prior art has following beneficial effect:
1, the variation that the present invention can the Real-Time Monitoring welding current is transfinited and alarm, effectively avoids unnecessary loss.
2, the present invention can improve product percent of pass.
Description of drawings
Fig. 1 is control principle block diagram of the present invention.
Fig. 2 is the circuit block diagram of the controller in Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
This battery butt welding machine monitoring device illustrated in figures 1 and 2, include butt welding machine 1, be provided with current sensor 2 in the welding circuit of described butt welding machine, the output of current sensor 2 is connected with the input of alarm controller 3, is provided with input signal translation circuit 31, voltage comparator 32 and warning output unit 33 in alarm controller 3.It is specifically worked like this:
Be sleeved on the current sensor 2 in the welding circuit of butt welding machine 1, welding current signal real-time Transmission during with butt welding machine 1 welding work pieces 4 is to alarm controller 3, alarm controller 3 is sampling resistor by its input signal translation circuit 31() this current signal is converted to voltage signal after, deliver to the input of voltage comparator 32, voltage comparator 32 is double threshold voltage comparators.Process through over-voltage comparator 32, when input signal was within two threshold voltages up and down of setting after treatment, voltage comparator 32 did not overturn, and its output keeps low level constant always; When input signal during higher than Upper threshold voltage or lower than next threshold voltage, 32 upsets of double threshold voltage comparator, its output becomes high level, the warning output unit 33 that drives the back is that audible-visual annunciator sends alarm signal, the alert welding current has surpassed setting range, should in time process, in order to avoid cause unnecessary loss.
Claims (3)
