Among this battery spraying equipment, battery 40 horizontal installation is in fixing device 10, and fixing device 10 can restrict battery 40 except rotating other degrees of freedom around self axis, because battery 40 horizontal setting, can reduce the material and gather to battery 40's bottom under the action of gravity, is favorable to the evenly distributed of material.

The spraying device 20 is arranged at the side part of the battery 40, the spraying device 20 is fixed, during the rotation of the battery 40, the spraying device 20 continuously sprays the material on the surface of the battery 40, if the battery 40 rotates for one circle, the material covers the side surface of the battery 40 for one circle along the circumferential direction, the more the number of the rotation of the battery 40 is, the thicker the material sprayed on the surface of the battery 40 is, here, the material can be glue which has the function of bonding between the battery 40 and the bottom groove of the battery box, and can also be other materials, such as insulating materials. As an example, the spraying device 20 includes a nozzle 21 having a flat structure, and the nozzle 21 has a width such that the width direction of the nozzle 21 is parallel to the axial direction of the battery 40 when it is installed, so that the coverage of the material on the surface of the battery 40 can be increased.

The sliding of the clamp plate 133 is achieved by the driving of a power take-off mechanism, which may employ a pneumatic principle or a hydraulic principle to output power to the clamp plate 133.

In order to limit the stroke of the clamping plate 133, two sensors may be arranged on the surface of the connecting seat 132 and along the moving path of the clamping plate 133, when the two sensors are triggered, the power output mechanism stops outputting power to the clamping plate 133, one sensor is used for preventing the clamping plate 133 from continuously advancing during the process that the clamping plate 133 is close to the battery 40 so as to avoid the clamping plate 133 excessively pressing the battery 40 to deform the battery 40, and the other sensor is used for preventing the clamping plate 133 from continuously retreating during the process that the clamping plate 133 is far away from the battery 40 so as to avoid the clamping plate 133 from being separated from the connecting seat 132.

It is to be noted that, since the vacuum chuck 131 is in contact with the end face of the battery 40, when it is necessary to coat the circumferential surface of the battery 40 near the end face, it is possible to be free from the influence of the vacuum chuck 131.

The battery spraying equipment further comprises a coating device 30, wherein the coating device 30 is arranged on the side of the battery 40 and is used for coating the material sprayed on the surface of the battery 40, so as to enlarge the coverage area of the material and form a relatively uniform coating on the surface of the battery 40, the coating device 30 can coat the material on the surface of the battery 40 along with the rotation of the battery 40 in the spraying process, for example, the material can be coated by a scraper 31 which is relatively fixed and arranged at a gap with the battery 40, or the material can be coated on the surface of the battery 40 after the spraying is finished and the rotation of the battery 40 is stopped, for example, the surface of the battery 40 is pressed by a pressing plate with an arc-shaped surface, so that the material is coated on the surface of the battery 40, or the material can be coated in other ways, which are not listed herein.
