Detailed Description

The present invention will be further explained with reference to the following detailed description and accompanying drawings:

Example 1

Referring to fig. 1, the device for guiding a roll of an aluminum-case battery into a case comprises: a rectangular frame 1 and four guide pieces 2, 3, 4, 5.

the inner dimension of the rectangular frame 1 is larger than the opening dimension of the aluminum case 6.

The four guide pieces 2, 3, 4 and 5 are respectively fixed on the inner sides of the middles of the four sides of the rectangular frame body 1 correspondingly, the guide pieces 2 and 4 are the same long guide pieces and are correspondingly connected to the long sides of the rectangular frame body 1, and the guide pieces 3 and 5 are the same short-side guide pieces and are correspondingly connected to the short sides of the rectangular frame body 1.

The specific connection mode is determined by the materials of the rectangular frame body 1 and the guide sheet, and the skilled person can choose the welding, bonding or integral forming mode to manufacture the rectangular frame body and the guide sheet.

the guide piece and the rectangular frame body 1 are preferably made of smooth and wear-resistant materials, such as steel, hard alloy and the like.

The width of each guiding piece is less than the width of the side of the rectangular frame 1 where the guiding piece is located, and is preferably 5mm, so as to ensure that the guiding piece can smoothly extend into the aluminum shell 6.

The guide piece has the contained angle rather than 1 limit of rectangle framework at place, and each contained angle is the same, preferably 30, each guide piece syntropy stretches out outside the rectangle framework 1, 2 by four guide pieces like this, 3, 4, 5 constitute a rectangle passageway that from top to bottom narrows gradually jointly, the guide piece stretches into just automatic assembly clearance of reserving out roll core 7 and aluminum hull 6 behind the aluminum hull 6, roll core 7 is through four guide pieces 2, 3, 4, 5 the guide directly falls into in the aluminum hull 6 (the length that the guide piece stretches out rectangle framework 1 is decided by the roll core 7 size of waiting to go into the shell, the rectangle passageway size that constitutes below four guide pieces equals or slightly is greater than roll core 7 size promptly), and can not collide with 6 perisporium of aluminum hull and cause the roll core damage.

The operation process of this embodiment is as follows:

referring to fig. 1, after the aluminum shell 6 is positioned, the rectangular frame 1 is positioned right above the aluminum shell 6, and the center of the rectangular frame 1 and the center of the aluminum shell 6 are on the same vertical axis; referring to fig. 2, rectangle framework 1 descends, and four guide pieces 2, 3, 4, 5 stretch into the opening of aluminum hull 6 thereupon, then transfer roll core 7 to rectangle framework 1 top, put down with vertical angle after the lower extreme that will roll core 7 contacts with the guide piece, roll core 7 and drop into aluminum hull 6 after the guide piece guide and accomplish the assembly in, rectangle framework 1 rises afterwards and breaks away from with aluminum hull 6, can transfer the aluminum hull after rolling up the core income shell to follow-up production station.

As for the lifting driving manner of the rectangular frame 1, those skilled in the art can freely design according to the prior art, and this specification gives an embodiment in the following example 2, but is not limited to this embodiment.

Example 2

The structure of the rectangular frame 1 and the guide pieces 2, 3, 4 and 5 in this embodiment is basically the same as that in embodiment 1, except that a vertical lifting mechanism is further included.

This vertical elevating system includes: the base 8 is used as a bearing part of the whole mechanism, and a positioning station of the aluminum shell 6 is located in the actual roll core shell entering production line; in order to position the aluminum shell 6 conveniently, a clamping groove 12 is formed in the surface of the base 8 and used for placing the aluminum shell 6 for positioning.

two guide posts 9 are symmetrically connected with two ends of the clamping groove 12 in a penetrating manner on the base 8, the guide posts 9 are perpendicular to the base and can be installed through sliding sleeves or directly connected in a penetrating manner, the upper ends of the two guide posts 9 are respectively perpendicular to two ends of the rectangular frame body 1 (the rectangular frame body 1 of the embodiment is used for matching the connection of the guide posts 9, the width of short edges of two ends is increased compared with that of the embodiment 1), and the lower ends of the two guide posts 9 are commonly and perpendicularly connected with a connecting plate 11; a cylinder 10 is fixed below the base 8 through a support, the piston rod end of the cylinder 10 points to the base and is vertically fixed with the connecting plate 11, and the rectangular frame 1 can be driven to ascend or descend through the cylinder 10.

The specific operation process is as follows:

The aluminum shell 6 is transferred to a clamping groove 12 of a base 8 by a manipulator equipped in a production line, the aluminum shell 6 is positioned, the center of the positioned aluminum shell 6 and the center of an upper rectangular frame 1 are on the same vertical axis, then a piston rod of an air cylinder 10 contracts to drive a guide post 9 to descend, and further the rectangular frame 1 descends, then a guide sheet on the rectangular frame 1 extends into an opening of the aluminum shell 6, then a mechanical clamping jaw 13 equipped in the production line clamps a winding core 7 to move right above the rectangular frame 1 (the specific structure of the mechanical clamping jaw 13 drives the mechanical clamping jaw 13 to move to a positioning mode of a specified position, which belongs to the prior equipment technology, the detailed description is omitted in the embodiment), the mechanical clamping jaw 13 descends, the winding core 7 is put down at a vertical angle after the lower end of the winding core 7 is contacted with the guide sheet, the winding core 7 falls into the aluminum shell 6 after being guided by the guide sheet to complete assembly, the aluminum shell 6 with the roll core inserted into the shell can be transferred to a subsequent production station.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
