Description

Basket clamping device for battery pole plate handling {BASKET CLAMPING DEVICE FOR HANDLING CELL OF STORAGE BATTERY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket clamping device for handling battery pole plates, and in particular, picking up several pole plates constituting the pole plate assembly carried from the conveyor belt in the process of handling the pole plate assembly during the manufacturing process of the battery and transporting them to the next processing step. Or a basket clamping device for battery pole plate handling, which is also used to transfer the pole plate assembly to the next step.

In general, the battery plates are made of lead or lead oxide, so it is very dangerous for a worker to handle them by hand. Therefore, in manufacturing a storage battery, an automation system for handling the electrode plate is required. The basket clamping device for battery pole plate handling is one component of this automation system.

1-4 illustrate a series of general processes of assembling the pole plates from the pole plates constituting the battery and inserting them into the battery case. In FIG. 1, the electrode plate 1 is made of lead or lead oxide, has a rectangular shape, and a terminal connection part 2 is formed at one upper side thereof, for example, and two protrusions 3 are formed at the lower part thereof (see FIG. 1). a). This pole plate 1 is packaged in an envelope 4 in the form of a package in which the lower and both sides are closed. At this time, the pole plate 1 has its entire body completely inserted into the envelope 4, and only the terminal connecting portion 2 is exposed through the upper opening (b in FIG. 1). In this way, the pole plates 1 inserted into the envelope 4 are configured with several, for example, six poles so that each terminal connection portion 2 may be alternately arranged left and right, so as to constitute the pole plate cluster 5 (Fig. C) of 1. The pole plate concentrator 5 thus focused is inverted so that the terminal connection part 2 side faces downward, and is coupled to a mold (not shown), so that the first terminal 6 and the second terminal row are arranged on both sides of the terminal connection part 2, respectively. The second terminal 7 is welded to form one pole plate assembly 8 (d, 2 and 3 of FIG. 1). In the subsequent process, the electrode plate assembly 8 is inserted into each compartment 10 of the battery case 9 to complete the storage battery (FIG. 4).

As described above, the basket clamping device for battery pole plate handling is used in the exaggeration in which the pole plate, the pole plate assembly or the pole plate assembly is transported, focused or inverted. The main components of the basket clamping device for handling battery pole plates are a pair of clamping plates which interact, and a plurality of such pairs of clamping plates are used. The pair of clamping plates are held open against the opposing side and can be gripped to hold the pole plate assembly or pole plate assembly.

5 to 10 show a typical basket clamping device for battery pole plate handling in the prior art.

The basket clamping device for handling the battery plate of the prior art is composed of an elongated rectangular frame (11). The square frame 11 is constructed on the support 18, 20 extending from the base 16 by the shaft 12, 14 on both sides at the position of the longitudinal axis thereof, and on the shaft 12 on the one side, the square frame ( A gear 22 for transmitting a rotational force to 11 is installed. Although not shown, the base 16 may be part of a carrier which controls the device by recharging the basket clamping device for handling the battery pole plate.

In the rectangular frame 11, upper fixing guide bars 24 and lower movable guide bars 26 are installed on both sides along the longitudinal direction thereof. Several fixed clamping plates 28 are installed at regular intervals between the fixed guide rods 24 at both sides, and several movable clampings at regular intervals, similar to the fixed clamping 28, between the movable guide plates 26 at both sides. The board 30 is installed. Each of the fixed clamping plate 28 and the movable clamping plate 30 are arranged up and down so that they can be coupled to the upper fixed guide bar 24 and the lower movable guide bar 26, respectively.

On the other hand, the front end portions of both movable guide rods 26 are movable in the longitudinal direction by the operation plate 32, and the operation plate 32 of the hydraulic cylinder 34 mounted on one side of the square frame 11. It is coupled to the working rod 36.

Such a basket clamping device for handling a battery pole plate of the prior art operates as follows.

For example, as shown in FIG. 1, a plurality of pole plates 1 are transported in an upright position by a conveyor (not shown) and for example to focus these pole plates 1 on the pole plate concentrator 5. When six pole plates 1 are focused, a basket clamping device for battery pole plate handling is used to move the focused pole plate condenser 5 to the next step.

The pole plate concentrators 5 are transported at regular intervals, and a basket clamping device for handling the battery pole plates is disposed on the upper portion thereof, and the pole plate concentrators 5 are cooperated with the fixed clamping plate 28 and the movable clamping plate 30. ) Can be lifted by holding. Each pole plate assembly 5 is disposed between each pair of fixed clamping plate 28 and the movable clamping plate 30 and the movable guide rod 26 is extended when the operation rod 36 is extended by the operation of the hydraulic cylinder 34. 5 and 6, the movable clamping plate 30 is moved toward the fixed clamping plate 28 so that the pole plate concentrator 5 is held therebetween.

However, in such a basket clamping device for battery pole plate handling in the prior art, as illustrated in FIGS. 9 and 10, the movable clamping plate 30 is moved toward the fixed clamping plate 28 so that the center point " O " "Is moved. That is, when the total thickness of the electrode plate assembly 5 varies according to the thickness change of the electrode plate 1 and the envelope 4 into which the electrode plate 1 is inserted, this means that the position of the center point “O” is changed. When the position of the center point "O" is changed, the position of receiving the pole plate concentrator 5 in the next process step of the battery clamping basket clamping device is bound to be different. In this case, the following process step requires a means for correcting the position of the electrode plate focusing body (5).

In the present invention, the invention was conceived in view of such a conventional situation, and a pair of clamping plates holding the electrode plate assembly can be moved relative to each other with the same amount of movement so as to hold the electrode plate assembly, regardless of the movement of both clamping plates. The center point between the pair of clamping plates is to be fixed at a certain position so that the pole plate condenser gripped by the clamping plate can be supplied to the correct position of the next step.

To this end, in the present invention, an elongated rectangular frame composed of side walls on both sides and end walls on both sides is constructed on a support extending from the base, and guide bars are installed on both sides of the upper and lower sides along the longitudinal direction in the rectangular frame, and the upper sides on both sides. Between the guide rod and the upper guide rods on both sides, there is provided a basket clamping device for handling a battery pole plate, in which a clamping plate is installed in a transverse direction. According to the present invention, a rotary plate formed with a U-shaped roller inserting opening is formed on both ends of the side wall of the rectangular frame at the front end side of each guide rod, and across both sidewalls of the rectangular frame at the upper roller inserting openings at both rotating plates. Rollers installed on both sides of the extended upper connecting plate are inserted, and rollers installed on both sides of the lower connecting plate extending across both side walls of the rectangular frame are inserted into the lower roller inserts. The tip of the rod is coupled, the tip of the upper guide rod is coupled to the lower connecting plate, and the operating rod of the hydraulic cylinder mounted on the end wall is coupled to the center of the upper connecting plate.

The invention is illustrated in FIGS. 11-18.

The basket clamping device for battery pole plate handling of the present invention is composed of an elongated rectangular frame 41 composed of side walls 38 on both sides and end walls 40 on both sides. The rectangular frame 41 is arranged on the support 48 and 50 extending from the base 46 by the shafts 42 and 44 on both sides at the position of the longitudinal axis thereof, and on the one side axis 42 the square frame ( A gear 52 for transmitting rotational force to 41 is mounted. Although not shown, the base 46 may be part of a carrier which controls the device by recharging the basket clamping device for handling the battery pole plate.

In the rectangular frame 41, guide rods 54 and 56 are installed above and below both sides along the longitudinal direction thereof. These guide rods 54 and 56 are mounted so as to be movable in the longitudinal direction by the respective brackets 57a and 57b. And between the upper guide rods 54 on both sides and the upper guide rods 56 on both sides, clamping plates 58 and 60 are respectively installed in the transverse direction.

On the front end side of each of the guide rods 54 and 56, a rotating plate 62 is arranged on the inner side of both side walls 38 of the square frame 41 by the shaft 63. U-shaped roller inserting holes 64 and 66 are formed above and below the rotating plate 62. The rollers 70 mounted on both sides of the upper connecting plate 68 extending across both side walls 38 of the square frame 41 are inserted into the upper roller inserts 64 from both rotating plates 62 and the lower side. The roller insertion hole 66 is inserted into the roller 74 mounted on both sides of the lower connecting plate 72, which also extends across both side walls 38 of the rectangular frame 41.

And the tip of the upper guide bar 54 is fixedly coupled to the upper connecting plate 68, the tip of the upper guide bar 56 is fixedly coupled to the lower connecting plate (72). The hydraulic cylinder 76 is mounted on the end wall 40 in the direction of the tip side of these guide rods 54 and 56 and the operation rod 78 is coupled to the center of the upper connecting plate 68.

The operation of the basket clamping device for handling a battery pole plate of the present invention is as follows.

The basket clamping device for battery pole plate handling of the present invention focuses and holds and concentrates the pole plate (1) prior to focusing on the conveyor belt having a plurality of vertical plate, which is loosely erected between the vertical plate and conveyed. It is used to transfer to next process stage.

First, in preparation, the operating rod 78 of the hydraulic cylinder 76 is in a contracted state, and the upper connecting plate 68 coupled thereto is connected to the side wall of the square frame 41 through the rollers 70 at both sides thereof. The rotating plate 62, which is arranged in the shaft 63 at 38, is placed in a rotated state clockwise (as seen in FIGS. 12 and 14 of the drawing). At this time, since the tip of the guide rod 54 on which the clamping plate 58 is installed is connected to the upper connecting plate 68, the guide rod 54 is moved to the right side (in FIG. 12 of the drawing). The roller 70 of the upper connecting plate 68 is inserted into the upper roller insert 64 of the rotating plate 62 to allow the upper connecting plate 68 to be organically coupled to the rotating plate 62. At this time, the clamping plate 60 is installed by pushing the lower connecting plate 72 in which the rollers 74 on both sides are inserted into the lower roller insert 66 at the clockwise rotation of the rotating plate 62. The lower guide bar 56 is moved to the sin side (see FIG. 12). Therefore, the upper guide rod 54 and the lower guide rod 56 are moved in opposite directions, so that the clamping plate 58 and the clamping plate 60 mounted on each of them are moved in a direction away from each other so that there is a sufficient space between them. Allow the plate plates 1 to be focused to be introduced with space.

In this way, the two clamping plates 58 to be focused on the pole plate 1 to which the square frame 41 is transported in the state where the two clamping plates 58 and 60 are "opened" are the two clamping plates of the square frame 41 ( 58) (60). After the pole plate 1 to be focused is introduced between the two clamping plates 58 and 60 of each pair, the hydraulic cylinder 76 is operated to extend the operating rod 78 so that the rotating plate 62 rotates counterclockwise. Through the rollers 70 and 72, the upper and lower connecting plates 68 and 74 connected thereto are pushed and pulled, respectively. As a result, the guide rod 54 connected to the upper connecting plate 68 moves to the left side, and the guide rod 56 connected to the lower connecting plate 74 moves to the right side. As the upper and lower guide bars 54 and 56 move, the pair of clamping plates 58 and 60 mounted on them move toward the other side, and the amount of movement of these upper and lower guide bars 54 and 56 is increased. By the same, the amount of movement that each pair of clamping plates 58, 60 moves toward the opposite side is the same. Therefore, the center point "O" between the clamping plates 58 and 60 moving toward the other side does not change its position. This means that the center position of the pole plate concentrator 5 of the pole plate 1 focused between these clamping plates 58 and 60 is always kept constant. Therefore, the pole plate concentrator 5 gripped and conveyed by the clamping plates 58 and 60 can be supplied to the correct position of the next step.

As described above, the present invention allows a pair of clamping plates holding the plate assembly to move relative to each other with the same amount of movement so that the plate holders can be held at a constant position regardless of the movement of the two clamping plates. It is to be fixed so that the pole plate focusing body that is gripped by the clamping plate and transported can be supplied to the correct position of the next step.
