The material loading platform 110 may be provided with a trough 110a, and the capacitor is accommodated and fixed in the trough 110 a. In some embodiments, trough 110a is an open trough 110 a. For example, the trough 110a may be a groove disposed on the surface of the material loading platform 110, the shape of the groove is adapted to the shape of the non-pin portion of the capacitor, and when the capacitor is placed on the material loading platform 110, the non-pin portion of the capacitor is at least partially accommodated in the groove, so that the groove is used to limit the capacitor.

Referring to fig. 1 and 2, in another embodiment, the trough 110a is a closed trough 110a disposed in the material loading platform 110, the material loading platform 110 is provided with a channel 111, two ends of the channel 111 penetrate through the material loading platform 110, a pin slot 113 is disposed on a side wall of the channel 111, the channel 111 is connected to the outside through the pin slot 113, the capacitor enters the trough 110a through one end of the channel 111, and the pin penetrates through the pin slot 113 and is at least partially exposed out of the material loading platform 110.
