Description
Technical field
The utility model relates to a kind of high precision roller press of battery pole piece.
Background technique
Electrodes of lithium-ion batteries is the important component of battery, when manufacturing lithium ion battery, is needed to battery pole piece
Strip carry out roll-forming, the roll squeezer for being accordingly used in electrodes of lithium-ion batteries is an important machining equipment, In
In the existing roll squeezer for electrodes of lithium-ion batteries, traditional lithium battery is all to use carbon black as conductive agent, is mostly adopted
Roll squeezer is bi-motor brake.Lithium battery large-scale use carbon pipe conductive agent the most at present, the requirement to roll squeezer
It can be higher and higher.Use carbon pipe as after conductive agent, with the long-time service of roll squeezer, roll is gradually worn out, the mistake of work
Difference can become larger, so that low to repetitive positioning accuracy after roll-in, pole piece thickness difference is big, generallys use high abrasion thus
Material prepares roll-in, but with prolonged use, always has abrasion for machine roller, while motor is vacantly to hang over pressure roller
Right side is caused live-roller deviation center increasing, is caused the final precision of machine not high, roller due to the influence of gravity
Pole pressure piece thickness is not accurate.There are also the pole piece chilling roller press that one kind generally uses, hard using the permanent gap structure of short change, deep quenching
The technology of roll, Belt Driven by Double Motor, but due to the factor of bi-motor braking, the consistency of braking can inevitably be not achieved, slightly
The phenomenon that some braking retardations will result in pole piece roll-in uneven thickness, paint dislocation inside pole piece.
Utility model content
Pole piece thickness is controlled in roll-in in order to solve the above technical problems, can be improved the purpose of the utility model is to provide one kind
The high precision roller press of the battery pole piece of the precision of degree.
The utility model proposes a kind of battery pole piece high precision roller press, including motor mounting groove and roll installation
Slot, the roll mounting groove are arranged in the side of motor mounting groove, are provided with motor and transmission device in the motor mounting groove,
The inside bottom of motor mounting groove is arranged in the motor, and the side of the transmission device is connected to motor, the transmission device
The other side and the first universal shaft and the second universal axis connection, the top of the second universal shaft, institute is arranged in first universal shaft
It states the first universal shaft and first roll is housed on roll mounting groove, first universal shaft, second universal shaft, which runs through, to be rolled
Roller mounting groove is equipped with second roll on second universal shaft.
Further, the bottom of the motor mounting groove and roll mounting groove is provided with bottom plate.
Further, the center line of the center line of the motor and the second universal shaft is arranged in the same horizontal line.
Further, first universal shaft is parallel with the second universal shaft installs.
Further, rolling roll slot is provided between the first roll and second roll.
According to the above aspect of the present invention, the utility model at least has the following advantages: the high precision roller press design of the battery pole piece
Motor, the roll of the upper end are no longer connected to motor respectively, and which prevent the weight of motor to the active force of roll, guarantee
The precision of distance between roll, therefore the precision of pole piece thickness is improved, it ensure that the consistency of roll transmission speed, improve
The surface quality of pole piece.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the high precision roller press of battery pole piece of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Embodiment: a kind of high precision roller press of battery pole piece, including motor mounting groove 1 and roll mounting groove 3, it is described
The side of motor mounting groove 1 is arranged in roll mounting groove 3, and motor 4 and transmission device 5, institute are provided in the motor mounting groove 1
The inside bottom that motor mounting groove 1 is arranged in motor 4 is stated, the side of the transmission device 5 is connected to motor, the transmission device
5 other side is connect with the first universal shaft 6 and the second universal shaft 7, and the upper of the second universal shaft 7 is arranged in first universal shaft 6
Side, first universal shaft 6 run through roll mounting groove 3, and first roll 8 is housed on first universal shaft 6, and the described 20000th
Run through roll mounting groove to axis 7, second roll 9 is housed on second universal shaft 7.
The bottom of the motor mounting groove 1 and roll mounting groove 3 is provided with bottom plate 2.
The center line of the center line of the motor 4 and the second universal shaft 7 is arranged in the same horizontal line.
First universal shaft 6 installation parallel with the second universal shaft 7.
Rolling roll slot 10 is provided between the first roll 8 and second roll 9.
The high precision roller press mainly moves motor position, is that motor is placed on the ground the shadow hanging without gravity
It rings, so that motor drives universal roll shaft rotation, for internal roller shafts without because gravity torque caused by hanging motor causes
Damage, theoretically perfect pole piece roller compression machine, it is more accurate to cause to adjust roll gap, and the roll-in thickness of pole piece is enable to close always
In a certain range, fluctuation range is small for the control of reason, and the roll of the upper end is no longer connected to motor respectively, prevents motor weight
To the active force of roll, the accuracy of the distance between roll ensure that, therefore improve the precision of pole piece thickness, ensure that roll passes
The consistency of dynamic speed, improves the surface quality of pole piece.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
