Description

Technical Field

[0001] This utility model relates to the field of automated production equipment for new energy batteries, and specifically to a battery cell clamping and handling platform. Background Technology

[0002] As a crucial component connecting battery chips and battery modules, the cell flange plays a vital role in the field of new energy vehicle batteries. The cell flange is the interface connecting the battery chip and the battery module, used to transmit electrical energy and data signals. Its functions include battery chip fixing, sealing, and conductive contact. Cell flanges are widely used in the new energy vehicle battery field, thus affecting the vehicle's range and safety performance. Regarding battery chip fixing, the cell flange protects the mechanical strength of the battery chip and prevents external forces such as vibration from affecting it; regarding battery chip sealing, the cell flange prevents leakage of the battery chip and electrolyte, thereby improving battery safety; regarding conductive contact, the cell flange ensures the reliability of the connection between the cells inside the battery module, thereby improving the battery's performance indicators.

[0003] In battery manufacturing, one process involves cell flange cutting. The purpose of cell flange cutting is to cut off the excess part of the cell flange to ensure the subsequent assembly of the cell. Based on the requirements of cell flange cutting, a platform for automatic clamping and transfer of cells needs to be designed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a battery cell clamping and handling platform that uses a movable lifting method to suspend and automatically unload the battery cells, thereby improving the battery cell handling efficiency while ensuring the flatness of the battery cell flange and improving the subsequent battery cell flange cutting accuracy.

The support plate is horizontally arranged on a linear module and has a U-shaped plate structure, with one side opening facing the clamping assembly. Vertical support plates are provided on both sides of the support plate. Two lifting cylinders are included, each located on the side of the vertical support plate with its output end facing upwards. The lifting slide is slidably connected to the vertical support plate in the vertical direction. The carrier plate is horizontally positioned above the lifting slide and fixedly connected to it. At least two through slots are formed on the carrier plate. At least two carriers are suspended within the two through slots and connected to the bottom of the carrier plate via connecting columns. A cell slot is formed on the carrier, penetrating the carrier vertically, with its walls extending downwards at an incline from the outside in. A cell is placed within the cell slot. At least two sets of pressing components are provided, each set corresponding to the edge of the cell slot.

[0006] Preferably, the pressing component includes a pressing cylinder and a pressing member, wherein the pressing cylinder is disposed at the bottom of the carrier and its output end is disposed towards the edge of the cell slot; the pressing member is connected to the output end of the pressing cylinder and is driven by the pressing cylinder to approach the cell slot so as to support the cell in the cell slot from below.

[0007] Preferably, the pressing component includes a connecting seat, a push block, and a rotating pressing plate, wherein the connecting seat is sleeved on the outside of the output end of the pressing cylinder and fixedly connected to the carrier; the connecting seat has a U-shaped push groove inside, the opening of the push groove faces outward, and a first sliding groove with a strip-shaped structure is formed on the inner side wall of the push groove.

[0008] Preferably, the push block is disposed in the push groove. The push block has a U-shaped block structure and is connected to the output end of the pressure holding cylinder. The U-shaped opening of the push block faces outward. A rotating shaft is inserted into the U-shaped opening of the push block. The two ends of the rotating shaft extend outward and are inserted into the first sliding groove, and move freely in the push groove.

[0009] Preferably, the rotating pressure plate is disposed within the U-shaped opening of the push block and is rotatably sleeved on the rotating shaft within the U-shaped opening of the push block; the rotating pressure plate has a second sliding groove with a strip-shaped structure, and the rotating shaft is slidably inserted into the second sliding groove, the two ends of the rotating shaft extending outward and rotatably inserted into the connecting seat; the outer end of the rotating pressure plate extends toward the cell slot and is used to press the cell in the cell slot.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a battery cell clamping and handling platform that uses a movable lifting method to suspend and automatically unload battery cells. This improves the efficiency of battery cell handling while ensuring the flatness of the battery cell flange and enhancing the subsequent precision of battery cell flange cutting.

[0012] This invention aims to provide a method for flange cutting of battery cells. Before flange cutting, the battery cell is received from the lifting arm and then transferred to a battery cell platform for flange cutting by a laser above the platform. Compared to traditional handling devices, to ensure the accuracy of subsequent flange cutting, this invention uses a suspended lifting method to support the battery cell and a nested collaborative side-support method to achieve the support and positioning of the battery cell. Specifically, this invention uses a horizontally arranged U-shaped support plate as the supporting structure. The opening of the U-shaped support plate faces the clamping assembly and is driven by the platform linear module to move back and forth linearly, so as to nest it above the battery cell platform during the feeding process. The two sides of the support plate are suspended by vertically arranged vertical support plates, and the two sides of the support plate are slidably connected to the vertical support plates in the vertical direction through lifting slides, and are driven by lifting cylinders to move up and down in the vertical direction for feeding and receiving. Multiple vertically penetrating openings are provided on the support plate. The device includes a through slot with a carrier suspended on its inner wall. A cell slot is correspondingly formed in the center of the carrier, and the wall of the cell slot is an inclined surface that gradually slopes downward from the outside to the inside. This inclined surface serves as a guide when the cell is picked up. Multiple sides of the carrier are equipped with holding components. The holding cylinders of the holding components drive the holding blocks to move closer to or away from the cell slot. When a cell needs to be picked up, the holding cylinders drive the holding blocks to extend from the outside into the cell slot to lift and position the cell, thus suspending it in the air. When a cell needs to be placed, the device moves and nests above the cell platform, and the holding cylinders drive the holding blocks to retract inward, placing the suspended cell into the clamping assembly.Furthermore, this utility model employs a method of converting single linear power into two actions: linear pushing and rotary lifting. This method of supporting the flange from below via rotary lifting, compared to direct pushing, avoids collisions with the suspended flange during lifting, which could cause bending of the flange surface, affecting its flatness and consequently impacting subsequent cutting accuracy. This effectively improves the precision of the flange cutting process and increases the cutting yield. Specifically, the holding cylinder is fixedly mounted on the side wall of the carrier via a connecting seat. The output end of the holding cylinder passes through the connecting seat and extends into the U-shaped push groove inside, driving the push block within the push groove to move back and forth linearly in the push groove. The push block is a U-shaped block structure with its U-shaped opening facing the battery cell slot and a rotating shaft inserted therein. Both ends of the rotating shaft extend into the first slide groove on the side wall of the first slide groove of the push block, to... When the rotating plate slides linearly within the pusher groove, it is guided and limited by a rotating shaft sliding within the first groove. Simultaneously, a rotating pressure plate is rotatably mounted on the rotating shaft, and a second groove is formed on the side wall of the rotating pressure plate. A rotating shaft is also inserted into the second groove, allowing it to slide freely within it. The outer side of the rotating pressure plate is an outward-extending pressure plate structure. When the holding cylinder drives the pusher block to move outwards, the pusher block, through its rotating shaft, drives the rotating pressure plate to move downwards towards the battery cell slot. Simultaneously, the rotating pressure plate slides towards the battery cell slot within the second groove, achieving synchronous linear and rotary motion. This motion method effectively supports and lifts the battery cell flange while avoiding collisions with the flange that could affect its flatness, and also effectively prevents motion interference caused by the linear motion of the pusher block.
