Description

The diaphragm paper pick-up unit

Technical field

The utility model relates to the battery manufacture field, is a kind of diaphragm paper pick-up unit specifically.

Background technology

Diaphragm paper is the vitals in the battery manufacture, and the effect of diaphragm paper mainly is that the both positive and negative polarity of battery is separated, and prevents short circuit, adsorbs simultaneously the electrolytic solution in the battery, guarantees higher ionic conductivity.The performance of diaphragm paper has determined interfacial structure, internal resistance and the electrolytical retentivity of battery.Owing to having a large amount of tortuous micropores that connect in the barrier film, ionophore in the electrolytic solution can freely pass through in micropore, migration forms the inside battery galvanic circle between both positive and negative polarity, and electronics then moves between both positive and negative polarity by the external circuit and forms electric current, and electricity supply and use equipment uses.Diaphragm paper needs through coil paper, scalds the processing procedures such as the end, insertion battery in use.To spool and after the diaphragm paper at the boiling hot end inserts battery, need to detect it, detection comprises three parts, be that foreign matter detects, crosses high detection and crosses low the detection, whether foreign matter detects the main battery inner bottom part that detects foreign matter, too high and to cross low detection mainly be whether detect the specification that diaphragm paper puts into behind the battery up to standard.Most important for the detection that diaphragm paper inserts in the battery, directly affect the quality of battery finished product.In the prior art, mainly be detection before inserting battery to the detection of diaphragm paper, be detection method and the device of 200710076009.0 patent of invention battery diaphragm paper sand hole such as the disclosed number of patent application of State Intellectual Property Office, can't realize the detection after diaphragm paper inserts battery.

The utility model content

The technical problems to be solved in the utility model is, provides a kind of diaphragm paper of realizing to insert the diaphragm paper pick-up unit that the foreign matter behind the battery detects, and realizes simultaneously the detection that diaphragm paper is too high and excessively low.

Technical solution of the present utility model is, a kind of diaphragm paper pick-up unit of following structure is provided, and comprises detection components and approach switch that depression bar is housed, is fixed with iron block on the described depression bar.

Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, first battery is fixed, diaphragm paper is inserted in the battery again, depression bar is vertically inserted in the battery again, the position of detecting iron block by approach switch reflects whether foreign matter is arranged in the battery, soon whether there will be foreign matter to be converted into the displacement of iron block on the depression bar, if the residing position of iron block is higher than under normal circumstances, thereby is detected by approach switch, and then by other equipment substandard product is rejected; This product has realized that effectively foreign matter detects in the battery, can select substandard product after diaphragm paper inserts, thereby improve qualification rate and the performance of product.

As improvement, described detection components is provided with spring, described spring housing is located on the depression bar, this decision design has two advantages, at first can ensure the active homing of depression bar, moreover, owing to being provided with spring, depression bar inserts the buffering that can be subject to spring in the battery, unlikely on the battery impulsive force excessive and affect battery fixingly reach follow-up detection.

As improvement, described diaphragm paper pick-up unit also comprises diaphragm paper height detection inductor, and diaphragm paper height detection inductor comprises a pair of for detection of diaphragm paper too high the first fiber sensor whether, the mutual correlation of described a pair of the first fiber sensor; This design can detect the too high phenomenon of diaphragm paper, thereby substandard product is rejected.

As improvement, described diaphragm paper height detection inductor also comprises for detection of diaphragm paper the second fiber sensor on the low side whether, described the second fiber sensor tilts to be installed in the side top of battery, detect the height of diaphragm paper by the refraction of optical fiber, accurately judge that whether diaphragm paper is on the low side in battery, further improved properties of product.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, diaphragm paper pick-up unit of the present utility model comprises detection components 4 and approach switch 2 that depression bar 1 is housed, is fixed with iron block 3 on the described depression bar 1; 2 one kinds of described approach switchs are to there being element---the displacement transducer of " perception " ability near its object, utilize approach switch the sensitivity characteristic near object to be reached the purpose of gauge tap on-off, thereby realize the detection to object, the approach switch in the present embodiment adopts the Hall-type approach switch.

Described detection components 4 is provided with spring 5, and described spring 5 is sheathed on the depression bar 1; One end of depression bar 1 is loaded in the detection components 4, and the other end is vacant, is used for inserting in the battery; Spring 5 also is positioned at detection components.

As shown in Figure 2, described diaphragm paper pick-up unit also comprises diaphragm paper height detection inductor, diaphragm paper height detection inductor comprises a pair of for detection of diaphragm paper too high the first fiber sensor 6 whether, described a pair of the first fiber sensor 6 mutual correlation are installed in battery top two side positions.

As shown in Figure 3, described diaphragm paper height detection inductor comprises that also described the second fiber sensor 7 tilts to be installed in the side top of battery 8 for detection of diaphragm paper the second fiber sensor 7 on the low side whether.

With Fig. 2 and 3 and Fig. 1 accompanying drawing and to describe be in order to reflect more intuitively the structure of this product respectively, because light sensor and approach switch all are arranged on side on the battery, therefore adopt different accompanying drawings to present.

Principle of work of the present utility model is as follows: adopt the utility model structure, first battery 8 is fixed, again diaphragm paper 9 is inserted in the battery 8, vertically insert depression bar 1 in the battery 8 again, because the buffer action of spring 5, the power of depression bar 1 can not affect the position of battery 8, reflect by the position that approach switch 2 detects iron block whether foreign matter is arranged in the battery, soon whether there will be foreign matter to be converted into the displacement of iron block on the depression bar 1, if the residing position of iron block is higher than under normal circumstances, thereby detected by approach switch, and then by other equipment substandard product is rejected; Whether too high by the first fiber sensor detection diaphragm paper of two mutual correlation simultaneously, whether the second fiber sensor 7 detects diaphragm papers on the low side; As long as three test sections have one detect defective just with it as bad part eject, can adopt pneumatic equipment that it is rejected; Arrange simultaneously that foreign matter detects and diaphragm paper cross high detection be because diaphragm paper too high might be that foreign matter causes also might be the dimensional problem of diaphragm paper own, therefore, need simultaneously detection could effectively guarantee product percent of pass.

Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.In a word, all various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
