Abstract
The utility model relates to the technical field of vehicle battery production, in particular to an improved short circuit testing machine which is used in a battery testing process. The improved short circuit testing machine comprises a machine body and a testing probe which is arranged on the machine body and is used for being connected to an external electrode group to be tested, the machine body is also provided with a ground wire connecting terminal, and the ground wire connecting terminal is provided with a ground wire which is connected to a total inlet wire ground wire. By arranging the special ground wire, a stable ground wire connecting system can be supplied, the testing failure rate can be effectively reduced, and unqualified short-circuit current flowing to the next working procedure is reduced.
Description
Technical field
The utility model relates to the car battery production technical field, is specifically related to the used improved short-circuit test machine of a kind of accumulator testing process.
Background technology
Current global automobile market, along with energy-conservation and cry environmental protection day by day improve and the influence of global financial crisis all has an immense impact on to sale of automobile, the hybrid power vehicle has become the main product on the automobile market gradually.The market of hybrid electric vehicle is estimated 2010 increasing gradually, and the global marketing automobile reaches 6,500 ten thousand, and hybrid electric vehicle will be above 2,000,000, and the occuping market share reaches 3%.What the purchase hybrid vehicle that Chinese Government proposes exempted from that this policy of purchase tax of 10% also will influence the consumer purchases the car idea, estimates 2012, and Chinese hybrid electric vehicle market will occupy 10% the market share.
The hybrid electrically Vehicular battery is the newly-increased great market of battery industry.Lead-acid accumulator is used for hybrid electric vehicle and electric motor car has great advantage, and it is cheap, monomer voltage is stable, security performance is high, and promptly makes the basis well.Great gap is compared or existed to domestic present production technology with external similar industry, still is that product quality all is still waiting to improve from production efficiency.The backwardness of production equipment and design defect also are to cause product quality and performances and even product percent of pass main reasons for decrease.
Adopt short circuit detector that utmost point crowd is carried out the short circuit Non-Destructive Testing; Improved the qualification rate of product greatly, made in process of production, can fulfillment process control; Thereby can avoid underproof semi-manufacture in becoming the product process, just to be excluded, can not flow into down production link one.Existing car battery production line short-circuit test machine does not have special-purpose ground wire; Ground wire is connected on the machine casing; Rely on 2 screw fixation test machines to serve as ground wire; Often generation does not detect the problem of negative high voltage value fault, thereby causes underproof short circuit battery to enter into next process, so that produces underproof battery product.
Summary of the invention
The technical matters that the utility model solves is the deficiency that overcomes prior art, provides a kind of effective reduction to detect mortality and the improved short-circuit test machine that reduces underproof short circuit battery inflow subsequent processing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
A kind of improved short-circuit test machine comprises body and is located at the detection probe that is used to be connected to outside utmost point crowd to be measured on the body that also be provided with the ground wire splicing ear on the said body, said ground wire connection terminal is provided with ground wire and is connected on the total input-wire ground wire.Be connected on the total input-wire ground wire through special ground wire is set, form the electrical grounding of standard criterion, stop the detection failure that causes owing to ground connection is bad; The phenomenon that prevents the failure of short-circuit test machine testing so effectively takes place; Prevented that effectively underproof short circuit battery from entering into subsequent processing, so greatly practiced thrift the production starting material, also improved the qualification rate of product; That is to say, improved product quality and reduced production cost.
Said body comprises shell and the transformer and the current sensing means that place in the shell, and transformer is connected with current sensing means, and transformer is provided with power supply wiring, and current sensing means is connected with detection probe.
Compared with prior art; The beneficial effect of the utility model technical scheme is: the utility model is through avoiding on the ground wire that short-circuit grounding wire is transferred to main line owing to the bad sum of errors error-detecting of bringing for the equipment testing process of the contact of ground wire; Reduce effectively and detect mortality and reduce underproof short circuit battery inflow subsequent processing, reduce defect rate, that is to say; Improve product quality, also reduced production cost simultaneously.
Description of drawings
Fig. 1 is the utility model short-circuit test machine structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is done further explanation.
Embodiment 1
As shown in Figure 1; Short-circuit test machine structural representation for the utility model; Comprise body and be located at the detection probe 1 and ground wire splicing ear that is used to be connected to outside utmost point crowd to be measured on the body, said ground wire connection terminal is provided with ground wire 2 and is connected on the total input-wire ground wire.Said body comprises shell 3 and the transformer 4 and current sensing means 5 that place in the shell, and transformer 4 is connected with current sensing means 5, and transformer is provided with power supply wiring, and current sensing means 5 is connected with detection probe 1.During use, the electric wire wiring at transformer place is connected to external power source, ground wire 2 is connected with the total input-wire ground wire, and detection probe 1 is connected 6 with utmost point crowd to be detected, can accomplish test process.
