Description

Technical Field

[0001] This utility model relates to the field of battery cell production technology, and in particular to a battery cell module loading device. Background Technology

[0002] The battery module is the most important component of a battery pack, serving as an intermediate energy storage unit between the individual battery cells and the battery itself. The battery module needs to be installed into a housing. In existing technology, the housing is transferred to the loading station under external force, with the opening facing upwards. Existing battery module loading equipment includes a positioning mechanism and a clamping mechanism, with the clamping mechanism positioned above the positioning mechanism. The battery module is moved by the conveyor line. When the battery module reaches the positioning station, it is positioned by the positioning mechanism, and the clamping mechanism clamps it, transferring it into the housing. However, the battery module is placed into the housing from top to bottom. During this clamping process, the battery module is suspended in mid-air, with its bottom unsupported, making it prone to falling from the clamping mechanism. This results in insufficient safety of the battery module during use with existing battery module loading equipment. Therefore, this invention proposes a battery module loading device. Utility Model Content

A stop bar is connected between the horizontal portions of the two fourth connecting plates located on the same side.

[0007] The adsorption assembly includes a horizontally arranged fifth connecting plate, with vertical connecting rods arranged around its perimeter. The connecting rods are vertically slidably connected to the side of the crossbeam. A bracket is connected to the lower end of the fifth connecting plate, and a silicone rubber buffer pad is connected to the bottom of the bracket. Multiple clearance grooves are distributed on the lower end of the silicone rubber buffer pad. A third cylinder for driving the fifth connecting plate to rise and fall is connected to the Z-axis moving module.

[0008] The Z-axis moving module is connected to the mounting plate via a rotatable base. The rotatable base has a through hole in the middle, and the Z-axis moving module is connected through the inner side of the rotatable base. The outer periphery of the rotatable base is provided with a gear ring.

The adsorption component is vertically mounted below the clamping component and can be used to press the battery cell module into the housing. The adsorption component includes a silicone rubber buffer pad with multiple clearance grooves distributed on its lower end face. When gripping the battery cell module, the adsorption component presses down, and the silicone rubber buffer pad presses against the upper end face of the battery cell module. The air in the clearance grooves is squeezed out, forming a negative pressure, thus eliminating the need for additional negative pressure equipment and saving equipment costs. The terminal of the battery cell module extends into the clearance grooves, and the silicone rubber buffer pad is relatively soft to prevent damage to the terminal. Attached Figure Description

After the material arrives at station 1, the first cylinder 2233 drives the third connecting plate 2232 to slide inward, thereby driving the stop bar 2236 to move directly below the cell module 4. The second cylinder 2235 drives the fourth connecting plate 2234 upward, thereby driving the stop bar 2236 upward to support the bottom of the cell module 4 and prevent it from falling. The XY axis moving module 211 drives the gripper assembly 22 to transport the cell module 4 to above the box-in station 3. The second cylinder 2235 drives the fourth connecting plate 2234 to reset, and the first cylinder 2233... The third connecting plate 2232 is driven to reset, the Z-axis moving module 213 drives the gripper assembly 22 downward, and the bottom end of the battery cell module 4 enters the battery cell mounting slot 51 on the housing 5. The first servo motor 22106 drives the first gripper finger 22102 to release, the second servo motor 22112 drives the second gripper finger 22108 to release, and the third cylinder 2225 drives the fifth connecting plate 2221 to move the bracket 2223 and the silicone rubber buffer pad 2224 downward, thereby pressing the battery cell module 4 into the battery cell mounting slot 51.
