Abstract
The utility model discloses a diaphragm micropore short circuit testing arrangement, including cylindrical copper billet, square copper billet, the examination diaphragm paper that awaits measuring, short circuit tester, black pen-shape metre and red pen-shape metre, short circuit tester right side below is provided with black pen-shape metre and red pen-shape metre respectively, and black pen-shape metre with red pen-shape metre be connected through the electric wire with cylindrical copper billet and square copper billet respectively, settle between cylindrical copper billet and the square copper billet have the examination diaphragm paper that awaits measuring. This diaphragm micropore short circuit testing arrangement provides one kind and judges whether there is the micropore bad phenomenon of diaphragm with the sound that the short circuit tester sent, and the effectual diaphragm that will have the micropore bad is chosen and is not flowed into the production line, effectively avoids leading to electric core after the electric core preparation finished product to discharge from great partially because of the diaphragm micropore, can lead to electric core flatulence or explosion bad phenomenon such as catching fire when serious.
Description
Technical Field
The utility model relates to a battery diaphragm detects technical field, specifically is a diaphragm micropore short circuit testing arrangement.
Background
With the rapid development of the electronic industry, the requirements of consumers on batteries are continuously improved, the interface structure of the batteries and the self-discharge performance of the batteries are determined by the performance of a diaphragm inside a lithium battery, and the attention of the lithium ion battery industry on the micropore short circuit of the diaphragm is continuously improved.
When the traditional diaphragm micropore detection method is used for detecting the diaphragm micropore, strong lamplight or a microscope is used for visual observation to see whether the diaphragm surface has the micropore, the method easily causes eye fatigue to cause misjudgment when the diaphragm micropore is visually detected, bad diaphragms flow into a production line, the self-discharge of a battery cell is large after the battery cell is manufactured into a finished product, and the battery cell expands or explodes to cause fire in serious cases.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a diaphragm micropore short circuit testing arrangement, whether to cause the tired erroneous judgement that leads to of eye easily when solving visual inspection diaphragm outward appearance and exist the micropore, lead to bad diaphragm to flow into the production line, electric core self discharge is bigger than normal after electric core preparation finished product, can lead to the problem of electric core flatulence or explosion phenomenon of starting a fire when serious.
In order to realize the above-mentioned purpose, the utility model provides a following technical scheme diaphragm micropore short circuit testing arrangement, including cylindrical copper billet, square copper billet, the examination diaphragm paper that awaits measuring, short circuit tester, black pen-shape metre and red pen-shape metre, the below is provided with black pen-shape metre and red pen-shape metre respectively about the short circuit tester right side, and black pen-shape metre with red pen-shape metre respectively with cylindrical copper billet and square copper billet be connected through the electric wire, settle between cylindrical copper billet and the square copper billet have the examination diaphragm paper that awaits measuring.
Preferably, the cylindrical copper block is disposed above a square copper block.
Preferably, the cylindrical copper block, the square copper block and the diaphragm paper to be tested are all horizontally placed, and the cylindrical copper block, the square copper block and the diaphragm paper to be tested are located on different horizontal lines.
Preferably, the cylindrical copper block and the square copper block are respectively attached to the upper surface and the lower surface of the diaphragm paper to be tested.
Compared with the prior art, the beneficial effects of the utility model are that: this diaphragm micropore short circuit testing arrangement provides one kind and judges whether there is the micropore bad phenomenon of diaphragm with the sound that the short circuit tester sent, and the effectual diaphragm that will have the micropore bad is chosen and is not flowed into the production line, effectively avoids leading to electric core after the electric core preparation finished product to discharge from great partially because of the diaphragm micropore, can lead to electric core flatulence or explosion bad phenomenon such as catching fire when serious.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. cylindrical copper block, 2, square copper block, 3, the diaphragm paper of awaiting measuring, 4, short circuit tester, 5, black pen, 6, red pen.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a diaphragm micropore short circuit testing device comprises a cylindrical copper block 1, a square copper block 2, diaphragm paper 3 to be tested, a short circuit tester 4, a black meter pen 5 and a red meter pen 6, wherein the black meter pen 5 and the red meter pen 6 are respectively arranged above and below the right side of the short circuit tester 4, the black meter pen 5 and the red meter pen 6 are respectively connected with the cylindrical copper block 1 and the square copper block 2 through electric wires, and the diaphragm paper 3 to be tested is arranged between the cylindrical copper block 1 and the square copper block 2;
the cylindrical copper block 1 is arranged above the square copper block 2; the cylindrical copper block 1, the square copper block 2 and the diaphragm paper 3 to be tested are all horizontally placed, and the cylindrical copper block 1, the square copper block 2 and the diaphragm paper 3 to be tested are located on different horizontal lines; the cylindrical copper block 1 and the square copper block 2 are respectively attached to the upper surface and the lower surface of the diaphragm paper 3 to be tested.
The working principle is as follows: before using this diaphragm micropore short circuit testing arrangement, need carry out simple structure to whole battery positive plate and know, adopt short circuit tester 4, short circuit tester 4's positive negative test table pen, black table pen 5 and red table pen 6 are connected to cylindrical copper billet 1 and square copper billet 2 respectively, square copper billet 2 is in the below, cylindrical copper billet 1 is above, during the detection with await measuring diaphragm paper 3 keep flat in the middle of square copper billet 2 and cylindrical copper billet 1, it has the micropore to slowly move cylindrical copper billet 1 and detect the diaphragm surface, square copper billet 2 and cylindrical copper billet 1 will produce the short circuit when having the micropore on the diaphragm paper 3 of awaiting measuring, short circuit tester 4 can send the warning sound simultaneously voluntarily, otherwise, if the diaphragm paper 3 of awaiting measuring does not have the micropore, short circuit tester 4 belongs to the state.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
