Description
Technical field
The utility model is related to lithium battery coiling around technical field, particularly a kind of winding pole piece tape transport length measuring mechanism.
Background technology
At present, the lithium ion battery produced with winding process, positive/negative plate and diaphragm in the manufacturing process of rolling step
Roller can be passed through and be transferred to progress auto reeling action at rolling needle mechanism, be finally completed the making of battery core；To winding electricity in technique
The length of pond positive/negative plate is distinctly claimed, if wound, to carry out the positive/negative plate length of battery core be not a similary length
Fixed value, it will the consistency of battery capacity is influenced, so all can in equipment in order to meet requirement of the technique to regular length
Increase the long function of survey of a positive/negative plate tape transport.
The long function majority of survey on existing winding apparatus is realized using encoder, however is deposited in actual application
The problem of have：(1) encoder transmitted between roller with pole piece exist it is opposite slide, i.e., roller turnning circle with encoder
There are deviations for turnning circle, and so as to cause the length that encoder measures, with pole piece physical length, there are deviations；(2) pole piece is crossing roller
During upper transmission, occur it is opposite slide, i.e., pole piece it is practical walk strip length with " number of turns " for crossing roller rotation, there are deviations；Encoder at this time
True pole piece length value can not be obtained, equipment will be unable to ensure the accuracy that winding battery core pole piece walks strip length, can not meet
Requirement of the technique to fixed pole piece length.
Invention content
The utility model technical issues that need to address are to provide a kind of winding pole piece that can accurately measure pole piece length and walk
Band length measuring mechanism.
To solve the technical issues of above-mentioned, the winding pole piece tape transport length measuring mechanism of the utility model is set including opposite up and down
The pole piece pressure roller and pole piece put cross roller, and the pole piece crosses roller and crosses roller center axis by pole piece to be connect with motor drive, the pole piece
It crosses roller center axis by shaft coupling with encoder to be connected, the encoder passes through code device signal line and controller input terminal phase
Connection.
Further, the pole piece pressure roller is connected with pressure roller driving mechanism, and the pressure roller driving mechanism includes and pole piece
The pole piece pressure roller fixing bracket of pressure roller rotation connection, is provided with stent mounting hole, the pole piece on the pole piece pressure roller fixing bracket
Pressure roller fixing bracket is fixed on pressure roller driving cylinder lower end, and cylinder trachea road is connected on the pressure roller driving cylinder.
Further, the pole piece pressure roller and pole piece cross roller outer surface and are provided with rubber layer.
With the above structure, the rotary shaft that the one end for crossing roller center axis is passed through shaft coupling and encoder by the utility model
Fixed to one piece, it is ensured that the two will not occur to slide relatively, and high consistency can be kept in rotary course；Secondly, to understand
Certainly opposite the problem of sliding, occurs when being transmitted on crossing roller for pole piece, needs to design a press-roller device, i.e., firmly presses pole piece
On roller is crossed, while in order to ensure not damage pole piece, rubber material is made on the surface for crossing roller and pressure roller.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the side structure schematic view that the utility model winds pole piece tape transport length measuring mechanism.
Fig. 2 is the main structure diagram that the utility model winds pole piece tape transport length measuring mechanism.
In figure：1 is pole piece pressure roller, and 2 cross roller for pole piece, and 3 be pole piece pressure roller fixing bracket, and 4 be stent mounting hole, and 5 is compile
Code device, 6 be code device signal line, and 7 be shaft coupling, and 8 cross roller center axis for pole piece, and 9 be rubber layer, and 10 drive cylinder for pressure roller,
11 be cylinder trachea road
Specific embodiment
As shown in Figure 1, the winding pole piece tape transport length measuring mechanism of the utility model, including the pole piece pressure roller being oppositely arranged up and down
1 and pole piece cross roller 2, the pole piece crosses roller 2 and crosses roller center axis 8 by pole piece to be connect with motor drive, and the pole piece crosses roller center
Axis 8 is connected by shaft coupling 7 with encoder 5, and the encoder 5 is connected by code device signal line 6 with controller input terminal
It connects, controller is PLC controller in present embodiment.
Further, the pole piece pressure roller 1 is connected with pressure roller driving mechanism, and the pressure roller driving mechanism includes and pole piece
The pole piece pressure roller fixing bracket 3 that pressure roller 1 is rotatablely connected is provided with stent mounting hole 4 on the pole piece pressure roller fixing bracket 3, described
Pole piece pressure roller fixing bracket 3 is fixed on 10 lower end of pressure roller driving cylinder, and cylinder trachea road is connected on pressure roller driving cylinder 10
11。
Further, the pole piece pressure roller 1 and pole piece cross 2 outer surface of roller and are provided with rubber layer 9.
The operation principle of the utility model is as follows：As shown in Figure 1, when equipment starts normal tape transport, PLC output press rolls drive
The signal that cylinder 10 of taking offence pushes is held to solenoid valve, at this time battery valve by compressed air by 11 supply cylinder of cylinder trachea road
Row pressing action is crossed pole piece pressure roller 1 and pole piece together with roller 2 securely fixes, it can be ensured that the same pole piece of length of pole piece tape transport
Crossing " length " that roller 2 rotates, unanimously (special, pole piece pressure roller 1 and pole piece cross 2 surface of roller setting rubber layer 9, and pole piece will be caused
Damage be reduced in the range of technological requirement；Manual control button is provided with beside mechanism simultaneously, it, can be with when needing threading
Cylinder is lifted, does not interfere with the normal threading work of operating personnel).As shown in Fig. 2, the rotary shaft homopolarity by encoder 5
Piece crosses roller center axis 8 and is fixed together with shaft coupling 7, it is ensured that the rotating cycle of encoder 5 crosses roller center axis 8 with pole piece
Rotating cycle is consistent, then converts the signal that encoder 5 exports by the calculation formula inside PLC, you can obtain pole piece and walk
The real time length of band when there is tape transport deviation and alarm and prompts operation or technical staff's processing equipment abnormal problem,
Effectively avoid the bad problem of battery core Capacity uniformity caused by pole piece length deviation.
Although the foregoing describe specific embodiment of the present utility model, those skilled in the art should manage
