Description

A kind of pruning tool

Technical field

The utility model relates to battery module mounting technology fields, and in particular to a kind of pruning tool.

Background technique

Kernel component of the battery pack as new-energy automobile, the quality of internal battery module assembling quality, direct shadow The overall performance of power-supply system is rung, and the assembly of battery pole ear is the key link in battery module assembling process, tab Extension consistency and planarization directly affect the assembling quality of tab, and then influence the performance of battery.

In the assembling process of tab, it sometimes appear that leading to the battery after assembly since tab this body length is unqualified The inconsistent problem of module tab length, when encountering such case, field worker generally will use scissors and trim to tab, Guarantee the consistency of battery pole ear length, but trimming position will lead to by scissors trimming tab and fold or bending occur, this When worker just need that fold or bending are calmed down and (such as tapped tab pad by wooden mallet on one piece of backing plate by other means Tab is so that it calms down), but need in addition to prepare special tool and station in this way, it is very troublesome.

Utility model content

The purpose of this utility model is to provide a kind of pruning tools, to solve in battery module assembling process because of trimming The unqualified tab of length and cause tab occur fold or bending phenomenon after calm down cumbersome problem.

To achieve the above object, pruning tool described in the utility model uses following technical scheme.

Pruning tool described in the utility model includes scissors, and scissors includes two hinged hilted broadswords, each hilted broadsword packet The blade of one end and the handle of the other end are included, roll rolling, the rotation axis of roll rolling are rotatably equipped on the handle of two hilted broadswords Line is parallel with the hinge axes of two hilted broadswords, the hinge axes of two handle upper rotary shaft lines to two hilted broadswords it is equidistant Two roll rollings constitute a pair of of rolling group, and pairs of rolling group can clamp sheet body and the sheet body flattening-out by out-of-flatness.

The beneficial effects of the utility model are: when discovery tab length is inconsistent, can pass through in tab assembling process Two mutually matched hilted broadswords of the pruning tool trim tab, if fold or bending occurs in tab after trimming, can lead to The rolling group crossed on pruning tool handle clamps fold or bending part, pruning tool or tab is then moved, by grinding in rolling group The effect of rolling of nip drum, which is realized, calms down tab.It is directly sharp after having trimmed the underproof tab of length using the pruning tool Fold or bending part are calmed down with the rolling group on pruning tool, do not need other preparation tool and station, it is very convenient.

Further, the quantity of the rolling group is one group.

Beneficial effect improved in this way is: general tab length is all shorter, so a section is respectively arranged on two handles The perimeter roll rolling composition rolling group roughly equal with tab length can meet requirement, and setting in this way can make the trimming work Lamps structure is simple, convenient processing and manufacture.

Further, the roll rolling for forming rolling group is mounted on the end of separate blade on each handle.

Beneficial effect improved in this way is: increasing the arm of force of the grinding pressure of roll rolling, improves the effect for calming down fold or bending Rate reduces the active force that worker applies, reduces the working strength of worker.

Further, the material of the roll rolling is hard nylon.

Beneficial effect improved in this way is: not damaging using hard nylon light weight, intensity height, abrasion performance and mating material Characteristic, not only make the pruning tool quality light and handy, moreover it is possible to guarantee that the pruning tool is durable enough, and avoid the pruning tool Damage to tab.

Further, the end of the separate blade of handle offers the stone roller that two sidewalls are oppositely arranged in the thickness direction of handle Nip drum holding tank, roll rolling are rotatably installed in the roll rolling holding tank.

Beneficial effect improved in this way is: roll rolling is enclosed in inside roll rolling holding tank, can provide one to roll rolling Kind protection, in addition, the structural strength that can be improved roll rolling installation site is arranged in this way.

Further, handle is D-shaped, and the straightway of D-shaped handle is back side, and two handles are installed back-to-back, two handles On roll rolling holding tank be provided with the segmental arc of D-shaped handle and position that straightway intersects, and the roll rolling on two handles The slot bottom of holding tank is obliquely installed, and the groove bottom of the roll rolling holding tank on two handles is in splayed together.

Beneficial effect improved in this way is: making that the handle arrangement is compact, intensity is high, and convenient for production.

In attached drawing: 1- hilted broadsword, the first fixed pin of 2-, 3- handle, 4- roll rolling, the second fixed pin of 5-, 6- roll rolling accommodate Slot, 7- groove bottom, 8- tab.

Specific embodiment

The embodiments of the present invention is described further with reference to the accompanying drawing.

The embodiment 1 of pruning tool described in the utility model includes scissors, and scissors includes being hinged on by the first fixed pin 2 Two hilted broadswords 1 together, each hilted broadsword 1 include the blade of one end and the handle 3 of the other end, and handle 3 is D-shaped, the straight line of handle 3 Section is back side, and two handles 3 are installed back-to-back, and one end end of the blade on two handles 3 far from hilted broadsword 1 is respectively provided with a stone roller The straightway of two handles 3 and the position of segmental arc intersection, and two are arranged in nip drum holding tank 6, two roll rolling holding tanks 6 The groove bottom 7 of roll rolling holding tank 6 is obliquely installed, and the groove bottom 7 of the roll rolling holding tank 6 on two handles 3 is in eight together Font, setting not only makes the handle 3 compact-sized in this way, but also improves the intensity of 3 end of handle, two roll rolling holding tanks A roll rolling 4 is respectively rotatably equipped with by the second fixed pin 5 in 6, the material of roll rolling 4 is hard nylon, and roll rolling 4 turns Shaft line is parallel with the hinge axes of two hilted broadswords 1, and two roll rollings 4 constitute a pair of of rolling group, and pairs of rolling group can clamp pole Ear 8 and by 8 flattening-out of the tab of out-of-flatness.

Above-mentioned roll rolling be also possible to other will not to the material that tab damages, such as soft metal, rigid plastics, Soft metal can be copper, calms down the fold of tab or bending by rolling for rolling group as long as can satisfy and will not injure pole The requirement of ear.

Rolling group on above-mentioned pruning tool is also possible to multiple groups, and multiple groups rolling group is arranged side by side, for the pleat on flattening-out tab Wrinkle or bending.

The groove bottom of above-mentioned roll rolling holding tank, which may not be, to be obliquely installed, and inclined groove bottom can be changed to two Orthogonal groove bottom, straightway of one of groove bottom perpendicular to handle.

The handle of above-mentioned pruning tool may not be D-shaped handle, such as can be cylindrical handle, separate blade on handle One end have enough spaces open up roll rolling holding tank be used to roll rolling is installed；It is also possible to be parallel to each other by two, cuts Face is the opposite handle for connecting composition of the flat strip plate of D-shaped, roll rolling be mounted on each handle two strip plates it Between, and it is mounted in the end far from blade.

In battery pole ear assembling process, when worker has found that tab length is inconsistent, the pruning tool pair can be passed through Tab is trimmed, and guarantees the consistency of all tab length, can if fold or bending phenomenon occurs in the tab after trimming To clamp tab using the rolling group of the pruning tool handle end, rolling effect and calm down tab using the roll rolling in rolling group On bending or fold.
