In order to reduce the heat loss, the applicant considers that the heat is introduced into the heating space from the bottom to the top, so that the temperature of the position close to the battery cover is higher, and through searching, the applicant finds that the related patent, such as application number CN201721301803.6, the utility model named as "heating system of storage battery resin drying kiln" adopts the structure, but the patent technology has the following problems: 1. in the scheme, the heating part adopts a steam heating pipe, hot air needs to be introduced from the outside through the steam heating pipe, and a part of heat is lost in the transmission process of the hot air from the outside to the drying kiln, so that the problem of low heat utilization rate still exists. 2. Because the moisture that carries in the steam is high, leads to humidity too big in the whole drying kiln, can lead to the battery to be in a humid state for a long time, can lead to the baffle paper to wet even when serious, and the performance also receives the influence, and when the battery removed from the drying kiln in, the water vapor on the battery meets cold and condenses into the water droplet at once, and whole drying kiln also needs special structure to drain away the heating in-process simultaneously and produces moisture. 3. Because the steam pipe needs to be connected with an external air source, if a steam pipeline is paved below a wider conveying chain plate, if a mode that a plurality of steam pipelines are simultaneously connected with the external air source is adopted, the pipelines are various; if the mode that single steam pipeline extends the laying back and forth is adopted, then the crooked position of pipeline is very much, and whole heating part can the uneven temperature. Both of these methods result in a complex structure and inconvenient maintenance.

Therefore, a simple and efficient heating system for heating the battery after the glue is applied to the cover is still needed.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example one

As shown in fig. 1, a local heating system after dispensing and cover closing of a storage battery includes a frame 1, in this embodiment, the whole frame 1 is a rectangular parallelepiped structure, a conveying plate 2 is disposed on an upper surface of the rectangular parallelepiped structure, and a battery 3 after dispensing and cover closing moves from one end of the conveying plate 2 to the other end of the conveying plate 2. As shown in fig. 2, a heat source 6 is disposed below the conveying plate 2, in this embodiment, the heat source 6 is a plurality of electric heating tubes disposed along the width direction of the conveying plate 2, and is laid under the conveying plate 2 at equal intervals and is distributed over the entire surface of the conveying plate 2 under the battery 3 to be baked, so as to ensure that the entire row of batteries 3 entering the baking area are uniformly heated at the same time, and the setting time of the glue in the battery cover is substantially the same. The machine frame 1 is provided with fixing rods 7 at the lower part of the conveying plate 2, the fixing rods 7 are provided with fixing plates 71, the electric heating tubes of the heat source 6 are fixed on the fixing plates 71 through connecting rods 72, each electric heating tube is fixed through two connecting rods 72 arranged at two ends, the fixing plates 71 are fixed on the machine frame (only one is shown in figure 2) through the two fixing rods 7, one end of each fixing rod 7 far away from the heat source 6 is provided with a power component (not shown in the figure), the power component can be of a cylinder, an oil cylinder, a screw rod and the like, the fixing plates 71 are driven to move up and down along the fixing rods 7 through the movement of the power component, and the heat source 6 is driven to be far away from or close to the battery. Preferably, the distance of the heat source from the battery is 80-150 mm.

As shown in fig. 1, the local heating system further includes a motor 4 disposed at a lower portion of the frame 1, and the motor 4 provides power to drive the conveying plate 2 to move so as to drive the battery 3 to advance.
