Field of the Invention The present invention relates to a battery transfer device, and more particularly, to a battery transfer device capable of automatically loading a battery transferred to a conveyor from a conveyor onto a pallet to improve productivity and automate battery manufacturing.

In general, in manufacturing batteries, a process of testing a state of a manufactured battery is performed. Recently, since it is difficult to test each of the batteries individually, the battery pack includes a pallet that can accommodate a plurality of batteries. Various tests are carried out after loading batteries on pallets. In addition, the pallet can be usefully used in the process of natural discharge by storing the relatively small size of the battery in a small space efficiently.

The end of the battery conveyor 10 is connected to a fixed table 20 that forms a predetermined space by a side wall 22 that is placed in a circular shape.

Inside the fixed table 20, a rotary table 30 that rotates about the center of the fixed table 20 is provided. The periphery of the rotary table 30 is formed in a circular shape so as to form a predetermined interval with the side wall 22 of the stationary table 20, and several transfer grooves 32 are formed on the periphery at regular intervals.

The transfer groove 32 is formed in a vertical direction as a semi-circular groove that can accommodate approximately half of the battery in the longitudinal direction, the upper and lower ends thereof are open. When the battery 12 is inserted into the conveying groove 32, the peripheral edge of the battery does not interfere with the inner circumferential surface of the side wall 22 of the fixed table 20 so that the battery is transferred to the conveying groove 32 when the rotating table is rotated. It should be able to achieve smooth rotation by

Then, immediately before the end of the battery conveyor 10, that is, a connection part (hereinafter abbreviated to an insertion position) connected to the fixed table 20, the battery 12 on the battery conveyor 10 is moved to the rotary table 30. A stopper 14 for controlling the feeding into the transfer groove 32 is provided.

Meanwhile, as shown in FIG. 2, a driving motor 40 is installed inside the fixed table 20, and coupled to the center of the rotary table 30 of the shaft 42 of the driving motor 40. It is configured to drive the rotary table 30. The drive motor 40 uses a servo motor or the like capable of rotating the angle as much as the feed groove 32 divides the circumference in the first drive signal. For example, when eight transfer grooves 32 are formed as shown in the drawing, the rotation angle of the driving motor in one operation will be 45 °.

A drop groove 24 penetrating downward is formed at a predetermined position on the lower surface of the rotary table, more specifically, at a point (falling position) on the trajectory drawn by the center of the transfer groove 32 when the rotary table rotates. The drop groove 24 should have a size that allows the battery to free fall.

In addition, at least one of the transfer grooves 32 should match the input position, and at least one of the transfer grooves 32 should be in the drop position.

On the side wall 22 near the feeding position of the fixed table 20, an input detecting sensor 26 for checking the presence or absence of a battery in the conveying groove 32 at the feeding position is installed, and On the adjacent side wall, a drop detection sensor 28 for checking the presence or absence of a battery in the transfer groove 32 reaching the drop position is provided.

At this time, the supply of the battery 12 is confirmed by the input detection sensor 26 (140), when the input of the battery is confirmed, the insertion groove which is supposed to be the first input of the XY table 50 is moved to the dropping position (150). . At this time, the position of the insertion groove 62 on the pallet 60 is preferably programmed in advance as described above to achieve the most efficient transfer operation. As described above, after the insertion groove 62 into which the first battery is inserted is located at the lower end of the drop position, the rotary table 30 rotates 160 by driving the motor. At this time, the rotation angle of the rotary table 30 is rotated by an angle (pitch angle) formed by the transfer groove and the transfer groove 32 adjacent thereto. Accordingly, the battery in the transfer groove 32 reaching the drop position is freely dropped through the drop groove 24 formed on the fixed table 20 and the insertion groove 62 of the pallet 60 located at the bottom thereof. Will enter. Then, the drop sensor 28 provided to the root of the drop position detects whether the drop of the battery is completed (170), the control unit determines whether the insertion groove 62 of the pallet 60 is the last 180, if not the last time, the battery operation is continuously performed by repeating the operation, and when the battery insertion is completed in the last insertion groove 62, the stopper 14 descends to completely block the battery 190. . The present invention has a structure for supporting the support structure of the fixed table 20 from the top of the XY table 50 in consideration of the interference between the pallet and the fixed table according to the movement of the XY table 50, or at least XY Interference with the transport within the coordinate range of the table shall not occur.

Subsequently, the pallet discharge conveyor 74 is operated to discharge 200 the pallet 60 which has been stacked. The X-Y table 50 returns 210 to its original position, receives a new pallet, repeats the operation, and achieves automatic battery loading.

According to the present invention, the number of the transfer grooves 32 on the rotary table can be added or subtracted as needed. The driving of the XY table is already widely known as a technique by a conventional coordinate control system, and a detailed description thereof has been omitted. .
