Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy vehicle manufacturing equipment technology, and in particular to a new energy vehicle battery assembly equipment. Background Technology
[0002] New energy vehicle batteries are one of the core components of new energy vehicles, providing power to the vehicles. Their main types include lithium-ion batteries, lithium iron phosphate batteries, and ternary lithium batteries.
[0003] During the manufacturing process, batteries need to undergo rigorous assembly, testing, and inspection, including cell sorting, stacking, welding, module packaging, thermal management system installation, performance testing, and safety testing.
[0004] In the assembly process of new energy vehicle batteries, traditional assembly equipment has many problems. On the one hand, the handling and positioning of battery modules mostly rely on manual labor or simple robotic arms, which is inefficient and difficult to guarantee positioning accuracy. This can easily lead to positional deviations during battery assembly, affecting the overall performance and safety of the battery. On the other hand, the appearance of the battery cannot be inspected after assembly. Appearance defects such as scratches, dents, cracks or contamination may not be detected in time. These defects can cause battery performance degradation or safety hazards in subsequent use. For example, cracks in the outer casing may cause moisture or short circuits inside the battery, increasing the risk of fire or explosion.
[0005] To address the above issues, we have launched a new energy vehicle battery assembly equipment. Utility Model Content
[0006] This utility model discloses a new energy vehicle battery assembly equipment, which aims to solve the technical problems in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A new energy vehicle battery assembly device includes an operating platform, a conveyor belt, and multiple individual battery cells. The conveyor belt is located on one side of the operating platform, and an assembly chassis is fixedly connected to the top of the operating platform. The multiple individual battery cells are arranged inside the assembly chassis, and connecting plates are provided between the positive and negative terminals of the multiple individual battery cells. Two multi-axis linkage robotic arms are arranged on one side of the operating platform, and an L-shaped plate is fixedly connected to one side of the top of the operating platform. The device also includes: a clamping mechanism located at the output end of one of the multi-axis linkage robotic arms for clamping and fixing the individual battery cells to ensure their stability during assembly; a welding mechanism located at the output end of the other multi-axis linkage robotic arm for welding the wires between the connecting plates of the individual battery cells together to form an electrical connection; and an appearance inspection mechanism located on the L-shaped plate for inspecting the appearance quality of the packaged individual battery cells to ensure that there are no bulges or defects.
[0009] In the new energy vehicle battery production workshop, the conveyor belt transports the individual battery cells to the workbench. A multi-axis linkage robotic arm drives the clamping mechanism to grab the individual battery cells and place them on the assembly chassis. Another robotic arm's welding mechanism welds the connecting pieces. After assembly, the appearance inspection mechanism inspects the batteries. Qualified products continue to circulate, while unqualified products are rejected.
[0010] In a preferred embodiment, the clamping mechanism includes a support frame, a clamping frame, two clamping plates, a clamping cylinder, a connecting block, and two connecting rods. The support frame is fixedly connected to the output end of one of the multi-axis linkage robotic arms. The clamping frame is fixedly connected to one side of the support frame. Both clamping plates are slidably connected inside the clamping frame. The clamping cylinder is fixedly connected inside the support frame, and its output end is fixedly connected to the connecting block. The two connecting rods are rotatably connected to both sides of the connecting block, and the ends away from the connecting block are rotatably connected to the corresponding clamping plates.
[0011] When the multi-axis linkage robotic arm moves above the single battery, the clamping cylinder pushes the connecting block, which in turn drives the two clamping plates to slide and clamp the battery within the clamping frame via the connecting rod. The robotic arm then precisely places the battery into the designated position on the assembly chassis, ensuring that the battery remains stable and does not shake during transport.
[0012] In a preferred embodiment, the welding mechanism includes a connector, a support plate, a welding head, and a connecting line. The connector is fixedly connected to the output end of another multi-axis linkage robotic arm. The support plate is fixedly connected to one end of the connector. The welding head is fixedly connected inside the support plate. The connecting line is fixedly connected to the input end of the welding head, and its other end is connected to an external welding machine.
[0013] After the individual battery cells are in place, another multi-axis linkage robotic arm drives the welding mechanism to move. The welding head is aligned with the connecting piece under the support of the support plate. The welding machine obtains power through the connecting line and quickly completes the welding of the connecting piece to the positive and negative terminals of the battery, forming the electrical path of the battery pack.
[0014] In a preferred embodiment, the appearance inspection mechanism includes a support rod, a first gear, a scanning plate, multiple appearance inspection probes, two limiting slide rails, a motor, and a second gear. The first gear is rotatably connected to the bottom of the L-shaped plate. The support rod is disposed inside the first gear and passes through the L-shaped plate. The scanning plate is fixedly connected to the bottom of the support rod. The multiple appearance inspection probes are evenly fixedly connected to the bottom and one side of the scanning plate. The two limiting slide rails are respectively fixedly connected to both sides of the support rod and are slidably connected to the first gear. The top of the L-shaped plate is fixedly connected to the motor. The output shaft of the motor passes through the L-shaped plate and is fixedly connected to the second gear, which meshes with the first gear.
[0015] After the battery is assembled, the motor drives the second gear to rotate, which in turn drives the first gear to rotate. Under the constraint of the limit slide rail, the support rod causes the appearance inspection probe on the scanning plate to scan the battery from all directions to detect whether there are defects such as bulges or scratches on the battery surface.
[0016] In a preferred embodiment, a lifting cylinder is fixedly connected to the top of the L-shaped plate, a connecting plate is fixedly connected to the output end of the lifting cylinder, and the support rod is rotatably connected to one end of the bottom of the connecting plate.
[0017] For batteries of different specifications, the lifting cylinder adjusts the height of the support rod through the connecting plate to keep the appearance inspection probe at a suitable detection distance from the battery, ensuring that appearance quality inspection can be accurately completed regardless of battery size.
[0018] In a preferred embodiment, baffles for use with individual batteries are fixedly connected to both sides of the top of the conveyor belt.
[0019] During the conveyor belt transport of individual batteries, baffles restrict the position of the batteries to prevent them from shifting or falling during transport, ensuring that the batteries are accurately transported to the workbench and providing stable material transport for subsequent clamping and assembly processes.
[0020] In a preferred embodiment, the conveyor belt, multi-axis linkage robotic arm, clamping cylinder, visual inspection probe, motor, and lifting cylinder are all electrically connected to external control equipment.
[0021] Throughout the battery assembly process, external control equipment coordinates the operation of various components according to preset programs, such as controlling the start, stop and speed of the conveyor belt, precisely controlling the motion path of the multi-axis linkage robotic arm, and monitoring the detection data of the appearance inspection probe in real time, so as to realize the automated and intelligent assembly production of the equipment.
[0022] The new energy vehicle battery assembly equipment provided by this utility model has the following advantages:
[0023] In this utility model:
[0024] 1. The cooperation between the multi-axis linkage robotic arm and the gripping mechanism enables the rapid and precise handling and positioning of individual batteries, which greatly improves assembly efficiency and accuracy, reduces manual intervention, and lowers errors;
[0025] 2. The multi-axis linkage robotic arm drives the welding mechanism, which can realize the movement of complex spatial trajectories, adapt to the welding needs of different positions and angles in the battery pack, and ensure the precise positioning and consistency of the welding points;
[0026] 3. The appearance inspection agency can quickly and accurately identify appearance defects of individual battery cells, such as scratches, dents, cracks, and contamination, through high-precision appearance inspection probes. This ensures that the appearance quality of the battery meets the standards and avoids affecting battery performance or causing safety hazards due to appearance problems. Compared with traditional devices, it greatly improves the quality of operation and efficiency of use. Attached Figure Description
