Lead-acid battery grabbing device

technical field

The utility model relates to the field of automation equipment, in particular to a device for automatically grabbing four batteries into trays twice after acid filling of lead-acid batteries.

Background technique

Electric vehicle batteries will generate heat after acid filling, and need to be cooled in a water tank immediately, and then sent to the formation area after initial cooling. The weight of electric vehicle batteries after acid filling is relatively heavy. For the convenience of logistics during subsequent formation, each battery four It is only loaded into the pallet and then transported. At present, battery manufacturers use the method of manually moving the battery into the pallet, which is labor-intensive, low in efficiency, and unsafe.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a grabbing device for lead-acid batteries, which includes a vertical frame, a horizontal frame passing through the vertical frame, and a The rotary deceleration motor at the end, the chuck shaft connected with the rotary deceleration motor, the chuck mechanism connected with the chuck shaft, the lifting ball screw installed in the vertical frame, the lifting servo motor connected with the lifting ball screw, and the horizontal frame A horizontal ball screw is installed inside, a horizontal servo motor connected with the horizontal ball screw, the chuck mechanism includes a chuck bracket connected with the chuck shaft, a static splint arranged at one end of the chuck bracket, and a chuck moving connected with the static splint The air cylinder, the limit block arranged on the chuck support against the moving cylinder of the chuck, the limit splint arranged at the other end of the chuck support, the clamping cylinder against the limit splint, the clamping cylinder connected with the clamping cylinder and slidingly arranged on the clamp One side of the moving splint rotating geared motor on the head bracket is provided with a forward rotation 90° proximity switch, the other side is provided with a reversed 90° proximity switch, and the front of the rotary geared motor is provided with a neutral proximity switch.

The advantages are: due to the setting of the chuck mechanism to grab the battery, it avoids direct contact between the workers and the battery that is heated after acid filling, and the safety is improved; the lifting ball screw and the horizontal ball screw are set, which can control the lifting and lowering of the chuck mechanism. Horizontal movement avoids scratching batteries and other items during work. A rotary deceleration motor and a 90° clockwise proximity switch and a 90° reverse proximity switch are installed so that the batteries can be put into the tray in the specified direction and order, neat and orderly.

Further, the movable splint is set in two pieces.

Furthermore, rubber plates are arranged inside the static splint and the movable splint.

The advantage is: the rubber plate is arranged on the movable splint and the static splint. Since the rubber plate has great elasticity, after the movable splint is clamped, the deformation of the surface in contact with the battery and the rubber plate can be prevented, and the battery can be clamped firmly.

The advantages of this device: using the lead-acid battery grabbing device, you only need to manually place the empty tray on the tray automatic conveyor belt, grab the battery, put the battery on the tray, and other actions are automatically completed without manual intervention; fully automatic battery grabbing The tray loading machine avoids direct contact between workers and the heated batteries after acid filling, and the batteries placed on the tray are neat and consistent, avoiding problems such as manual misplacement, skewed placement, etc., which cause difficulty in formation and connection, and low connection efficiency.

detailed description

The lead-acid battery grabbing device, as shown in Figure 1-2, includes a vertical frame 1, a horizontal frame 2 passing through the vertical frame 1, and a rotating gear motor arranged at the bottom of the vertical frame 1 3. The chuck rotating shaft 4 connected with the rotary reduction motor 3, the chuck mechanism 5 connected with the chuck rotating shaft 4,

A lifting ball screw 6 is arranged in the vertical frame 1, a lifting servo motor 7 connected with the lifting ball screw, a horizontal ball screw 8 is arranged in the horizontal frame 2, and a horizontal servo motor 7 connected with the horizontal ball screw 8 motor 9,

Collet mechanism 5 comprises the collet support 10 that links to each other with collet rotating shaft 4, is arranged on the static splint 11 of collet support 10 one ends, the collet moving cylinder 12 that links to each other with static splint 11, offsets with collet moving cylinder 12 and is arranged on The limiting block 13 on the chuck bracket, the limiting splint 14 arranged at the other end of the chuck bracket 10, the clamping cylinder 15 that is offset against the limiting splint 14, and the clamping cylinder 15 are connected and slidably arranged on the chuck bracket 10 The movable splint 16,
