Compared with the traditional method of setting the heat source in the jig assembly 3, there will be more circuits at the bottom of the jig assembly 3. When there are more circuits, the wiring will be messy and complicated, which is inconvenient for maintenance. In addition, because the battery jig needs to be constantly taken in and out of the cavity, and the frequent movement will cause poor signal contact. In the battery heating fixture, the battery 4 is heated by the base assembly 2, the battery base 2 and the cavity assembly 1 are fixedly connected, and the battery base 2 and the fixture assembly 3 are detachably connected. Since the battery 4 is heated by the base assembly 2, there is no circuit on the fixture assembly 3, which avoids the occurrence of complex wiring, poor circuit contact, etc. In addition, the heat source on the base assembly 2 can be powered on in advance for heating, so as to achieve the purpose of preheating, reduce the battery baking time, and thus improve production capacity.

The heating pipe 22 is "S" shaped and is arranged between the heating plate 23 and the base body 21. The wire of the heating pipe 22 is fixed above the fixture base. The wire runs from the side of the fixture base to the bottom of the vacuum cavity 11, and then is connected to the outside of the cavity assembly 1 through an aviation plug, so that the heating pipe 22 is provided with electric energy through the wire, so that the heating pipe 22 provides a heat source for the heating battery 4. A buffer 24 is arranged on the surface of the heating plate 23 close to the fixture assembly 3, and the buffer 24 is used to prevent friction between the heating plate 23 and the fixture assembly 3. In this embodiment, the buffer 24 is a Teflon tape.

[0028] In some embodiments, the base assembly 2 further includes a micro switch 26 , which is disposed on two diagonal corners of the base body 21 , and the micro switch 26 is used to detect whether the battery fixture is placed in a specified position.

[0029] In some embodiments, the base assembly 2 further includes a guide stopper 25, the guide stopper 25 and the base body 21 are detachably connected, four guide stoppers 25 are provided, and the four guide stoppers 25 are provided at the four corners of the base body 21. Specifically, both ends of the base body 21 are provided with elongated grooves 211, the guide stopper 25 is connected to the elongated grooves 211 by screws 251, and the position of the guide stopper 25 and the base body 21 can be adjusted by adjusting the position of the screws 251 in the elongated grooves 211.

[0030] See attached Figure 2 and attached Figure 4 As shown, in some embodiments, the jig assembly 3 includes a connecting piece 31, and the guide limit piece 25 is connected to the base body 21. Specifically, the connecting piece 31 is an annular structure, and the connecting piece 31 is sleeved on the four guide limit pieces 25.

For example, when a cylindrical battery is to be heated, the groove is set to a cylindrical shape; when an aluminum shell battery is to be heated, the groove is set to a rectangular parallelepiped. Therefore, when heating batteries of different models, the battery guide 33 with grooves of different shapes can be replaced according to the battery model. Compared with the prior art, a battery heating jig can only produce batteries of fixed models or similar models. For example, an aluminum shell battery jig can only produce aluminum shell batteries, but not cylindrical batteries. After the heat source is placed on the base assembly 2, and the base assembly 2 serving as the heat source and the jig assembly 3 are detachably connected, the conversion of the aluminum shell and the cylindrical battery jig can be achieved by quickly replacing the battery guide 33, that is, according to the model of the battery to be heated, a battery guide 33 that is compatible with it can be selected. The battery heating jig is suitable for batteries of different models, thereby improving the compatibility of the product.
