[0073] Specifically, the guide rail on the battery cell production equipment is long, and if the rail groove is arranged on the battery cell production equipment for flow, the entity forming the rail groove is long, resulting in an increase in the volume of the sliding rail 280, an increase in the occupied space, and an increase in the weight, and at the same time, the rail groove needs to be arranged open upward, which is easy to accumulate foreign matter and increase wear, and the bottom of the substrate 300 is provided with the rail groove, which can avoid the above problems.
[0074] In some specific embodiments of the utility model, the bottom of the substrate 300 can be provided with parts forming the rail groove to reduce manufacturing cost, facilitate maintenance through replacement, and reduce use cost.
