Technical Field

The utility model relates to the technical field of battery pole piece production, in particular to a moving structure of a battery pole piece in a rolling process.

Background

The battery pole piece is one of the main components of the battery, and the production process of the battery has high requirements on the surface smoothness and precision of the main roller when the battery pole piece is rolled. The battery pole piece rolling mill is key equipment for producing batteries, mainly comprises a frame and a pair of rolling rolls arranged on the frame through bearings, and ensures the precision of the rolled battery pole piece by a main roll and is also a key function of the battery pole piece rolling mill.

The battery grade piece continuously runs at the same position of the rolling roller, so that the abrasion of a certain position of the rolling roller is easily caused, and the same main roller cannot be used after the battery pole piece model is replaced.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a moving structure of a battery pole piece in a rolling process. This structure has reduced the wearing and tearing of motor pole piece to rolling roller same position, guarantees the usability of battery pole piece same rolling roller under the change width condition.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a moving structure of a battery pole piece in a rolling process comprises an air expansion shaft, a trimming assembly, a dust removal assembly, a swing roller assembly, an unreeling rack and an unreeling bottom plate; the air expansion shaft, the trimming assembly, the dust removal assembly and the swing roller assembly are all fixed on the unreeling rack; the unreeling machine frame can move along the direction of the central axis of the battery pole piece rolling roller on the unreeling bottom plate.

Further, a linear guide rail parallel to the electrode plate rolling roller is arranged on the unreeling base plate, and a sliding groove corresponding to the sliding rail is arranged on the unreeling rack; the unreeling base plate is fixedly provided with a driving device for driving the unreeling rack to move, and the moving end of the driving device is fixedly connected with the unreeling rack.

The device further comprises two sensors and a control unit, wherein the two sensors are respectively positioned at two ends of the rolling roller of the battery pole piece and used for detecting the limit position of the battery pole piece on the rolling roller; the two sensors, the control unit and the drive device as an actuator constitute an electronic control system.

The utility model adopts the technical scheme to produce the beneficial effects that:

the driving device drives the unreeling support to move to drive the pole piece to move, the working position of the pole piece on the rolling roller is continuously changed, the battery pole piece can be effectively prevented from continuously running at the same position of the rolling roller, irreversible abrasion of a certain position of the rolling roller is caused, the service life of the rolling roller is prolonged, and time and cost are saved.

In the figure, the device comprises an unreeling support 1, an air expansion shaft 2, a trimming assembly 3, a dust removal assembly 4, a swing roller assembly 5, a driving device 6, a linear guide rail 7, an unreeling base plate 8, a sensor support 9, a sensor 10, a sensor 11, a fixing plate 12 and a connecting plate.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

The following is a more specific example:

referring to fig. 1 to 3, the present embodiment includes an unreeling bracket overall structure, an unreeling base plate, a driving assembly, and a detecting assembly; the key points are as follows: the structure drives the unreeling support 1 to move to drive the pole piece to move, so that the position of the pole piece on the main roller continuously and actively moves.

The unreeling bracket 1 is of an integrally moved structure and comprises an unreeling air expansion shaft 2, a trimming assembly 3, a swing roller assembly 5, a dust removal assembly 4 and the like; the air expansion shaft 2, the trimming assembly 3, the swing roller assembly 5 and the dust removal assembly 4 are all arranged on the unreeling support to form an integral unreeling support structure; unreel bottom plate 8 and place on the factory building ground, through the bolt fastening.

The driving assembly comprises a linear guide rail 7 and a driving device 6; the linear guide rail 7 is arranged on the unreeling base plate 8, and the unreeling support 1 is arranged on the linear guide rail 7; the fixed end of the driving device 6 is arranged on the unreeling base plate 8, and the movable end of the driving device is connected with the unreeling bracket 1 through a connecting plate 12; the driving assembly drives the unreeling support 1 to move on the linear guide rail 7 through the driving device 6, and drives the pole piece to move.

The detection assembly comprises a sensor for detection and a sensor bracket; the sensor 9 for detection is arranged on the feeding side of the main machine through a sensor 10 bracket; the sensor 9 is used for detecting the position of the pole piece and preventing the pole piece from moving out of the effective application range of the roll surface.

The air expansion shaft, the trimming assembly, the dust removal assembly and the swing roller assembly are arranged on the unreeling bracket to form an integral structure, and the pole piece penetrates through the assemblies through the rolling roller; linear guide installs on unreeling the bottom plate, and drive arrangement stiff end installation is fixed on unreeling the bottom plate, removes the end and passes through the connecting plate and unreel leg joint, and drive arrangement drive unreels the support and removes about the drive pole piece to make the pole piece last reciprocating motion in the position on rolling the roller.

And controlling the left and right movement speed of the unwinding device according to the movement speed of the set driving device, thereby controlling the reciprocating speed of the pole piece on the rolling roller.
