| SN | Description | Remark |
| 1. | Manual feeding, taking the sealing surface of the electric core as the benchmark, lift up from the bottom of the electric core to ensure the consistency of the upper benchmark; The long side cylinder is locked, the short side cylinder is locked, the upper reference cylinder is unlocked, and the lower end of the fixture adopts a spring positioning mechanism. The spring is elastically deformed to ensure that the cell shell is not scratched during precise positioning; | |
| 2. | Pre weld the cover plate and shell first, and then fully weld after fixing the position. | |
| 3. | The clamping part is not in overall contact with the cell, and the middle is hollowed out to prevent excessive extrusion pressure on the cell; Manual blanking: when the battery moves to blanking, the battery cylinder unlocks, the battery cell pops up, and the material is taken manually. The short side is clamped by a rotating cylinder, and the electric core is placed and taken from the side, which is convenient to operate. |
| SN | Description | Remark |
| 1. | The laser output head is driven by a three-axis high-precision mechanical module to ensure the accuracy of the hardware; Using high-precision algorithm and controller, accurate laser excitation power and path; Press the assembly mechanism up before welding, and then fully weld the top cover to ensure the product qualification rate; The exhaust pipe and filter shall be made of fire-retardant materials, and the connecting parts shall be connected with steel rings. |
| SN | Description | Remark |
| The upper cover of the equipment is composed of sheet metal and Tan acrylic panels, and safety gratings are installed to ensure the safety of operators. The human-machine interface of the equipment is designed according to the existing structure of the company, and the welding parameters are visual and traceable. |
| SN | Item | Index | Remark |
| 1. | Time efficiency = Actual operation time: load time - planned downtime (failure, material switching) Load time: production hours - planned downtime Production hours: normal working hours Planned downtime: morning and evening, rest, spot check, cleaning, etc |
≥99.00% | |
| 2. | Performance improvement= Theoretical tempo: theoretical production time of a single product |
100% | |
| 3. | Product qualification rate= Fixed loss: tape splicing, coil changing, etc |
≥99.50% | |
| 4. | CMK Equipment capacity index CMK index only considers short-term dispersion and emphasizes the influence of equipment factors on product quality. Test requirements: the extracted data is continuous; It is assumed that the operator, measuring tools and raw materials are not affected; Only consider the influence of a single factor of the equipment. (that is, the operator must be skilled and competent; the measuring tools must meet the requirements and have been calibrated; the same batch of materials; and the inspectors meet the requirements.) Generally, 10 groups of 100 samples are sampled for measurement within about one hour after the production of the machine is stable. |
