1. Precise positioning of lithium battery components

Suitable positioning technology and experience are required, as well as the ability to realize efficient processing and calibration systems according to the requirements of mechanical positioning and image processing. In order to maintain accuracy in the long term, control of the camera or positioning table needs to be realized, as well as precise positioning, including mounting design.

2. Vacuum processing of battery components

There are not only simple vacuum chambers and furnaces, but also the mechanism of vacuum chamber operation process and liquid application equipment. Extensive knowledge of special vacuum equipment and parts such as vacuum pumps, piping and valves is required.

3. Laser welding of lithium battery components

If possible, depending on individual needs, knowledge and results of various lasers such as CO2, YAG, LED, fiber, etc. For example, laser welding of thin battery foil, welding of throttle housing and cover, welding of resin instead of metal, etc. The most suitable welding method is suggested according to the specification and selection of the welding machine.

4. Pressing of lithium battery components

Skills and experience in handling various presses, such as pneumatic, hydraulic and servo, are required. We have achieved a wide range of achievements, from testing production levels of robotic arm presses to machine platforms that use servo motors to produce products and torque at controlled speeds with high precision and quality.

5. Dimensional measurement of lithium battery components

We use laser displacement gauges, image processing equipment, and contact and non-contact sensors to measure dimensions in a variety of ways. In the production machine, it is impossible to measure the correct size by measuring equipment alone. Therefore, it is necessary to maintain full accuracy, including mounting vibration, etc.

6.Resistance welding of lithium battery components

The quality and correctness of resistance welding associated with production machinery has a great impact on loading work. For this case, we select the most suitable welding method according to the specification and the recommended welding material.

7. Image processing

Experience with image processing is required, such as positioning, missing parts, scratches, etc. It responds to the shape, accuracy and agility of the object and to advanced image processing by combining the most appropriate camera, lighting and processing equipment. It then needs to respond to continuous image processing of long objects using licensor cameras.

8. Improve assembly accuracy

The machine is always processing, since it becomes an object to improve the accuracy. Therefore, in addition to processing machines, there are technologies for assembling machines with improved accuracy, such as assembling machines for processing machines. These machines with improved assembly accuracy can maintain accuracy for a long time.

9.Lithium battery assembly wiring technology

Consider the visual effect and long-term stable use. The focus should be on minimizing the stress during operation and selecting the most suitable wiring material.

10.Static electricity protection of lithium battery components

Static electricity has a destructive effect on work and disturbs the stability of electrostatic film transport. Therefore, it is necessary to eliminate the generated static electricity by using technologies that prevent it from being generated. Static electricity generated by machines is almost always caused by stripping charges or frictional charges. Every effort is made to avoid these charges and to prevent static electricity by constructing effective neutralization methods through various structures and neutralization devices.

11. Drying room

The manufacture of moisture-prone items, such as lithium-ion batteries, requires an ultra-low humidity environment. Lubricants will not produce the same effect when using ordinary actuators in this environment, so special care should be taken. Due to the low humidity of the environment, it is necessary to take appropriate measures to prevent static electricity. Appropriate measures are available and can be used according to the desired humidity level.

12. Explosion-proof measures for lithium battery packs

Machines that use solvents may require explosion-proof measures. There are various explosion-proof technologies and experiences, such as safer explosion-proof and pressure-resistant explosion-proof.

13. In response, keep the battery installation clean

13. In response, keep the battery installation clean

The use of ordinary clean room can prevent 0.5m contamination. Cell manufacturing has different levels of contamination. If cleanliness levels are set at the same level as semiconductor installations, cell manufacturing levels are inadequate and costs may increase unnecessarily. Appropriate knowledge, skill and experience are required to keep cell manufacturing equipment clean, remove it from contamination, and set the facility to the desired level of cleanliness.
