Cylindrical secondary battery handler}

The present invention relates to a secondary battery, and more particularly, to a cylindrical secondary battery handler having a cylindrical shape.

A secondary cell or a storage battery refers to a device that converts external electrical energy into chemical energy, stores it, and generates electricity when needed. The name "rechargeable battery" is also used to mean that it can be recharged multiple times. Commonly used secondary batteries include lead storage batteries, nickel-cadmium batteries (NiCd), nickel hydrogen storage batteries (NiMH), lithium ion batteries (Li-ion), and lithium ion polymer batteries (Li-ion polymer).

Meanwhile, with the development of wireless IT devices such as smartphones and IOTs as well as electric vehicles, the demand for secondary batteries, which is a power supply source, is rapidly increasing.

In addition, secondary batteries of various shapes are required according to the application range of secondary batteries, and secondary batteries are also used in IT devices such as wireless earphones called Apple's Airpods. The anterior shape also needs to be optimized.

In particular, in the case of wireless earphones called Apple's Airpods, the demand for cylindrical secondary batteries is expected to increase rapidly as cylindrical small secondary batteries are used.

When the tray 30 is fixed by the tray fixing part 800, the transfer targets are sequentially or a plurality of transfer targets are seated in the insertion groove 31 of the tray 30 by the transfer unit 300 to be described later.

On the other hand, when all the transfer targets are seated in all of the insertion grooves 31 of the tray 30, the tray 30 is released by the tray fixing unit 800, and the tray seating unit of the second tray support unit 420 ( 412 is moved to the lower side of the upper flange portion 33 of the tray 30 supported by the tray fixing portion 800.

When the movement of the tray seating part 421 of the second tray support part 420 is completed, the second tray lifting part 700 descends for transport of the tray 30 so that the upper flange part 33 of the tray 30 is The tray seating portion 421 of the second tray support portion 420 is supported by the tray seating portion 421 of the second tray support portion 420 and the tray unloading position 202 in a state in which the tray 30 is supported. Transfer the tray 30 to the furnace.

When the tray 30 is located at the tray unloading position 202, the second tray lifting part 700 rises to support the bottom of the tray 30, and from the tray seating part 421 of the second tray support part 420 It is lifted.

When the tray 30 is lifted from the tray seating portion 421 of the second tray support portion 420, the tray seating portion 421 of the second tray support portion 420 is placed in a place for transport of the next tray 30. Go to 202.

Meanwhile, it is preferable that the tray exchange between the first tray lifting part 500 and the first tray support part 410 and the tray exchange between the second tray support part 420 and the tray fixing part 800 be made simultaneously.

In addition, it is preferable that the tray exchange between the first tray support part 410 and the tray fixing part 800 and the tray exchange between the second tray support part 420 and the second tray lifting part 700 be made simultaneously.

The transfer unit 300 is a cylindrical electrode assembly in the insertion hole 31 of the tray 30 located in the loading unit 200 by picking up the cylindrical electrode assembly 10-the transfer object-located in the loading unit 100 (10) Various configurations are possible as a configuration in which the -transfer target- is placed vertically.

As an example, the transfer unit 300 may include at least one grip unit 310 for gripping a transfer object and a grip unit to insert the transfer object into each insertion groove 31 of the tray 30 at the place position 202 It may include an XY moving robot 320 for moving 310 in the XY direction.

The grip part 310 is a configuration for gripping a transfer target, and various configurations are possible according to a gripping method of the transfer target.

As an example, the grip part 310 is a pair of grip members 331 and a pair of grip members 331 that are linearly moved in a horizontal direction so that a cylindrical transfer object can be gripped therebetween, It may include a driving unit 332 to move.

As shown in FIGS. 13A and 13B, the grip member 331 may have a cylindrical transfer object in a cross-sectional shape and a concave surface facing the transfer object, as shown in FIGS. 13A and 13B.

The concave groove formed in the grip member 331 may have a V shape, a U shape, or the like.

On the other hand, the grip member 331 needs to be moved up and down for seating of the object to be transferred to the insertion groove 31, and the transfer unit 300 includes a grip unit 310, that is, a grip member 331. It may include a vertical drive unit 314 to move up and down.

The vertical drive unit 314 may individually move each grip unit 310 up and down, or may move all of the plurality of grip units 310 at once.
