[0040] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model. Therefore, one feature mentioned in the specification is used to explain one feature of one embodiment of the utility model, and it is not implied that each embodiment of the utility model must have the explained feature. In addition, it should be noted that the specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise stated, the described combination is not intended to be limiting.

[0041] The principles and structures of the utility model will be described in detail below in combination with the drawings and examples.

[0042] As an example, refer to the accompanying drawings Figures 1-5 The utility model provides a kind of net chain type furnace zone, it include: net chain body 1 and several top pins 2, every two top pins 2 are oppositely arranged to form a group, for jointly supporting battery piece.

[0043] Each of the said thimbles 2 comprises a support 3 connected with the said chain body 1 and a thimble body 4; the said thimble body 4 is detachably connected with the said support 3.

[0044] In the embodiment, the thimble body 4 is detachably connected with the support 3, so that the user can replace the thimble body 4 at any time. Therefore, when the chain type furnace belt is used for a long time, the thimble body 4 will be worn due to the contact with the battery piece. When the wear reaches a certain degree, the user needs to detach the worn thimble body 4 from the support 3 and replace it with a new thimble body 4 in time. In this way, the production cost of the user is low, and the subsequent processing steps of the battery piece will not be affected.

[0045] The thimble body 4 does not need to be replaced together with the chain body 1 when the chain body 1 needs to be replaced, and the replacement time does not need to be waited for too long. In this way, the worn thimble body 4 can be prevented from being unable to stably support the battery piece, and even the battery piece can be prevented from falling on the chain body 1. In addition, the contact mode of the worn thimble body 4 and the corresponding battery piece can be prevented from changing from point contact to surface contact. The increase of the contact area can cause the sintering of the edge of the battery piece to become worse. When the thimble body 4 is severely worn and the chain body 1 is slightly worn, only the new thimble body 4 needs to be replaced, and the chain body 1 does not need to be replaced together, thereby reducing the production cost.

In this way, each group of thimbles 2 can better and more stably support the battery piece, and the chain body 1 can simultaneously transmit the same number of battery pieces as the number of columns of thimbles 2, thereby improving the transmission efficiency of the chain body 1. In the embodiment, four columns of thimbles 2 are provided on the chain body 1.

[0049] The support 3 is made of Cr20Ni80. Of course, the material of the support 3 also includes but is not limited to any one of aluminum alloy, tungsten steel alloy, iron, copper and titanium alloy, thereby prolonging the service life of the support 3.
