Background technology
Perfect along with the widespread use of lithium-ion electric pool technology and production technology, the market share of lithium ion is also more and more higher, and enterprise must control the qualification rate of product well for the cost that meets the demand in market and reduce product.The bad phenomenon of the potential positive and negative electrode short circuit of some flexible packing lithium ion batteries or negative pole and aluminum plastic film short circuit, if positive and negative electrode or negative pole and aluminum plastic film are short-circuited, after battery perfusion electrolytic solution, can cruelly leak electrolytic solution a very long time, battery also can short circuit be smoldered or corrode simultaneously.Therefore before shipment, need lithium battery to shelve for a long time, whether qualifiedly so just can detect lithium battery, but can have a strong impact on like this shipment cycle, and the open-assembly time of the negative pole of some defective products and the short circuit phenomenon of aluminum plastic film is very long, is difficult to guarantee shipment quality.Also have at present some detection methods, measure exactly with test pencil, the precision of this metering system is low, also there will be the situation of error in judgement in production run, causes a lot of complaints.Therefore, production technology and pick-up unit etc. support the use the qualification rate that can directly have influence on lithium battery.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, accurate positioning, can continued operation and the battery short circuit that can enhance productivity detect fixture.
The technical scheme that the utility model adopts is: the utility model comprises pedestal, be arranged on several battery core locating devices on described pedestal and be positioned at the back up pad of described several battery core locating devices tops, on described pedestal, be also provided with and suitable some to measuring the lug utmost point of battery core both positive and negative polarity, on described several battery core locating devices, be equipped with bayonet slot, in described back up pad, be provided with cylinder, the output terminal of described cylinder be provided with the lug compact heap extremely suitable with described measurement lug and with the suitable bayonet of described bayonet slot.
The output terminal of described cylinder is also provided with web joint, and described lug compact heap and described bayonet are all arranged on described web joint.
On described web joint, be provided with several guide pillars, described several guide pillars are all slidably connected with described back up pad.
The two ends of described back up pad are all fixedly installed side plate, and described back up pad is fixedly installed on described pedestal by described side plate.
The beneficial effects of the utility model are: because the utility model comprises pedestal, be arranged on several battery core locating devices on described pedestal and be positioned at the back up pad of described several battery core locating devices tops, on described pedestal, be also provided with and suitable some to measuring the lug utmost point of battery core both positive and negative polarity, on described several battery core locating devices, be equipped with bayonet slot, in described back up pad, be provided with cylinder, the output terminal of described cylinder be provided with the lug compact heap extremely suitable with described measurement lug and with the suitable bayonet of described bayonet slot, when battery core detects, first the described measurement lug utmost point and described bayonet are electrically connected with measuring instrument, again battery core is placed on described battery core locating device, control described cylinder, described lug compact heap and bayonet are down moved, when being all pressed in described measurement lug by described lug compact heap, extremely goes up the positive and negative lug of battery core, and when described bayonet inserts described bayonet slot, described measuring instrument can judge that whether battery core is qualified, so, the utility model is simple in structure, easy to use, battery core accurate positioning can make the result of measurement also more accurate, can continued operation in the process detecting, the speed detecting is fast, can greatly enhance productivity.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises pedestal 1, be arranged on several battery core locating devices 2 on described pedestal 1 and be positioned at the back up pad 3 of described several battery core locating device 2 tops, on described pedestal 1, be also provided with and suitable some to measuring the lug utmost point 4 of battery core both positive and negative polarity, on described several battery core locating devices 2, be equipped with bayonet slot 5, in described back up pad 3, be provided with cylinder 6, the output terminal of described cylinder 6 be provided with the lug compact heap 7 suitable with the described measurement lug utmost point 4 and with the suitable bayonet 8 of described bayonet slot 5, in the present embodiment, described battery core locating device 2 is battery core locating piece, its quantity has two, described battery core locating piece is made of metal, the described measurement lug utmost point 4 has two pairs, described bayonet 8 has two, described lug compact heap 7 has two.
The output terminal of described cylinder 6 is also provided with web joint 9, and described lug compact heap 7 and described bayonet 8 are all arranged on described web joint 9, can make like this manufacture of the present utility model and installation become more simple and convenient.
On described web joint 9, be provided with several guide pillars 10, described several guide pillars 10 are all slidably connected with described back up pad 3, and in the present embodiment, described guide pillar 10 has two, one end of described guide pillar 10 is fixedly connected with described web joint 9, and the other end and described back up pad 3 are slidably connected.
