It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Lithium ion batteries are widely used in various fields such as mobile phones, computers, electric vehicles and the like at present due to the advantages of high voltage, large specific energy, wide working temperature range, large specific power, stable discharge, long storage time and the like. The diaphragm is used as one of the key materials of the lithium ion battery, and has the functions of isolating the positive electrode and the negative electrode, preventing short circuit and allowing lithium ions to freely pass through in electrolyte. The current commercialized membranes are polyolefin membranes, including high density polyethylene membranes and polypropylene membranes, and the melting points of the two membranes are respectively 130 ℃ and 165 ℃, and the two membranes are easy to melt and shrink under the condition that a battery is overheated, so that the anode and the cathode are in short circuit, and serious safety accidents of explosion and fire of the battery are caused.

Therefore, in order to prevent fire, the thermal stability of the separator needs to be improved by avoiding melting of the separator, and the thermal stability of the separator is generally improved by applying an organic powder coating on the surface of the separator, and then performing thermal radiation crosslinking on the membrane surface through an ultraviolet lamp to enhance the mechanical strength of the separator.

In the prior art, the heat radiation crosslinking mode is as follows: the membrane surface of the diaphragm is subjected to heat radiation by an ultraviolet lamp, and a device used for a heat radiation crosslinking process in the prior art is a lithium battery diaphragm ultraviolet crosslinking device, wherein in the heat radiation crosslinking process, the diaphragm needs to be cooled; specifically, the lithium battery diaphragm ultraviolet crosslinking device in the prior art comprises an ultraviolet lamp, wherein an air inlet device is arranged at one end of a lamp box of the ultraviolet lamp, an air outlet device is arranged at the other end of the lamp box of the ultraviolet lamp, and the air outlet quantity is larger than the air inlet quantity; the air inlet device and the air outlet device are both connected with the lamp box, so that the inner cavity of the lamp box is cooled; the inlet guide roller and the outlet guide roller are respectively arranged on two sides of the bottom end of the lamp box; the diaphragm passes through the lamp box through the inlet guide roller and is led out through the outlet guide roller, the diaphragm is suspended in the ultraviolet lamp box, and further the diaphragm at the bottom of the lamp box is also cooled.

The air cooling principle in the prior art mainly utilizes the fact that the air exhaust volume is larger than the air inlet volume, one end of a lamp box exhausts air, the other end of the lamp box enters air, and when the air exhaust volume is larger than the air inlet volume, fresh air is continuously supplied into the lamp box, so that the cooling of an inner cavity of the lamp box and a diaphragm is realized.

Although air cooling in the prior art has a certain cooling effect, the temperature of the inner cavity of the lamp box is higher under the high-temperature heat radiation of an ultraviolet lamp in the continuous production process, and the diaphragm can be ignited due to insufficient cooling only by virtue of air cooling; and the diaphragm in the suspended state is easy to have the problems of folds, unstable shaking state and the like under the influence of air supplementing flow. If the production line is shut down accidentally, air intake and air exhaust stop, which causes the temperature of the inner cavity and the diaphragm of the lamp box to be too high, even the potential safety hazard of ignition can occur, and adverse effects are brought to production.

In view of the above, in order to avoid the diaphragm from being overheated and catching fire and improve the quality of the diaphragm in the diaphragm ultraviolet crosslinking process, through research and continuous experiments, the applicant improves the lithium battery diaphragm ultraviolet crosslinking device in the prior art, introduces a cooling roller to improve the suspension state of the diaphragm in the heat radiation process, and solves the problem of insufficient cooling of the diaphragm by air cooling.
