Description

Technical Field

[0001] The utility model relates to the field of volatilization drying devices, in particular to a volatilization drying device for producing lithium battery foil coating adhesives. Background Art

[0002] Lithium battery foil coating adhesive is a special material used in the manufacturing process of lithium batteries. Its main function is to firmly adhere electrode materials (such as active substances, conductive agents, etc.) to electrode foil (usually copper foil or aluminum foil) to form a complete electrode sheet. This adhesive is essential to ensure the stability of the electrode structure and the overall performance of the battery. Lithium battery foil coating adhesive is usually composed of polymer compounds. These compounds have excellent adhesion, electrolyte corrosion resistance and certain mechanical strength. They can maintain stable performance during battery charging and discharging, and prevent electrode materials from falling off or stratification. In the production process of lithium battery foil coating adhesive, the adhesive coated on the electrode foil needs to be volatilized and dried. The main purpose is to promote the rapid volatilization of the solvent in the adhesive through heating and hot air control, thereby obtaining a dry and solidified adhesive coating.

[0003] During the volatilization drying process, most existing adhesives are dried using hot air circulation. Due to the one-way hot air duct, the hot air distribution may be uneven. The hot air speed in some areas is faster, causing the adhesive in these areas to dry quickly, while the hot air speed in other areas is slower, resulting in a relatively slow drying speed. This uneven drying will affect the final quality and performance of the coating and may cause problems such as cracks, warping or falling off on the coating surface. At the same time, uneven drying will prolong the drying time, which will reduce production efficiency and increase production costs.

[0004] Therefore, in view of the fact that most of the existing adhesives mentioned above adopt hot air circulation for drying during the volatilization drying process, since the one-way hot air duct may cause uneven hot air distribution, which may lead to inconsistent drying speed on the adhesive coating surface, a volatilization drying device for the production of lithium battery foil coating adhesive can be designed, which adopts multiple adjustable hot air outlets to ensure uniform hot air and consistency of drying speed. Utility Model Content

[0005] In order to overcome the problem of volatilization and drying of existing adhesives, most of them adopt hot air circulation for drying. However, the one-way hot air pipe may cause uneven hot air distribution, which may lead to inconsistent drying speed on the adhesive coating surface.

[0006] The technical solution of the utility model is as follows: a volatilization drying device for producing lithium battery foil adhesive, comprising a drying box, a rotating cover and a heating box; a rotating cover which can be rotatably used to seal the drying box and can drive external airflow into the drying box is provided above the drying box, a heating box for burning fuel to generate heat energy and uniformly introduce it into the drying box is provided on one side of the drying box, a guide pipe is installed on the heating box near the drying box, a plug-in pipe is provided inside the end of the guide pipe away from the heating box, a connecting main pipe is installed on the side of the plug-in pipe away from the outlet pipe, five groups of square clamping sleeves are horizontally installed on the side of the connecting main pipe away from the plug-in pipe, a square clamping pipe is provided inside the square clamping sleeve, a connecting branch pipe is installed on the side of the square clamping pipe away from the square clamping sleeve, four groups of connecting rotating shafts are horizontally installed on the lower end of the connecting branch pipe, a nozzle is provided below the connecting rotating shaft, and the nozzle is rotatably connected to the connecting branch pipe through the connecting rotating shaft.

[0007] Preferably, by opening the rotating cover, the lithium battery foil coated with the adhesive is placed in the drying box in turn, and then the heating box is started to burn the fuel to generate heat energy, and then the hot air is evenly discharged through the connecting main pipe and the connecting branch pipe to volatilize and dry the adhesive on the lithium battery foil. The uniform distribution of the hot air means that the heat and air flow can evenly cover the surface of the lithium battery foil coated with the adhesive, thereby ensuring that the solvent in the adhesive can be quickly and evenly evaporated and dried, which greatly improves the drying efficiency and shortens the production cycle. At the same time, the uniform hot air distribution can avoid the problem of uneven drying caused by local overheating or overcooling. In this way, the adhesive coated on the lithium battery foil can maintain a consistent drying speed and temperature during the drying process, thereby ensuring the stability and consistency of the drying quality.

[0008] Preferably, a display panel is installed on the outside of the drying box, and a humidity sensor is provided on one side of the display panel and extends through the drying box into the interior thereof. A thermometer is provided on the side of the display panel away from the humidity sensor and extends through the drying box into the interior thereof. Rectangular arrays of ventilation holes for ventilation and heat dissipation are provided on the lower sides of the drying box, and five groups of rectangular snap-in slots are provided laterally on the upper side of one side of the inner wall of the drying box. A rotating column is installed on one side of the upper end of the drying box, and a hole placement plate is provided on the inner side of the drying box. Support columns are installed at the corners of the lower end of the hole placement plate. First, pick up the hole placement plate and place it inside the drying box until the support columns touch the bottom of the inner side of the drying box. Then, the lithium battery foil coated with adhesive is placed on the hole placement plate in turn, and then the rotating cover is closed. During the drying process, the value is reflected on the display panel through the detection of the thermometer to avoid excessive heat or excessive low heat. At the same time, the humidity condition inside the drying box is detected by the humidity sensor. If there is too much heat energy, it may gather to form fog. The humidity value can be timely understood and the heating box can be adjusted through the operation panel.

By pulling the handle, the rotary cover is rotated open with the drying box through the rotary column. After the lithium battery foil is placed, the rotary cover is closed by pushing the handle. During the drying process, the motor drives the rotating shaft to drive the fan blades to rotate along the rotating ring to generate wind force, thereby driving the external air flow through the circular hole on the rotary cover into the drying box, then through the holes on the hole placement plate, reaches the bottom of the drying box, and then flows out from the ventilation hole, so that air circulation is formed inside the drying box, avoiding the accumulation of hot air to form fog, which causes the humidity inside the drying box to increase. At the same time, it can ensure that the heat flow distribution inside the drying box is more uniform, avoiding the phenomenon of local overheating or overhumidification in the drying box.

[0010] Preferably, a rectangular sealing cover is provided above the heating box, an inlet pipe is installed on the upper end of the rectangular sealing cover, a telescopic valve is provided on the outside of the connection between the inlet pipe and the rectangular sealing cover, and an electromagnetic control valve is installed on the outside of the telescopic valve.

Then, the telescopic valve is opened through the control of the operation panel and the electromagnetic control valve, so that external air can enter the heating box through the inlet pipe.

[0011] Preferably, a burner is provided inside the heating box, columns are installed at the corners of the lower end of the heating box, and an operation panel is installed on one side of the outside of the heating box. When a certain amount of air enters the heating box, the telescopic valve is closed through the control of the operation panel, and then the burner is started to burn the fuel and convert it into heat energy. The heat energy then enters the connecting main pipe through the outlet pipe and reaches the connecting branch pipe, and then is ejected through the nozzle.

[0012] Preferably, an oxygen sensor is provided on one side of the operating panel, which passes through the heating box and extends deep into the interior thereof. The oxygen sensor measures the oxygen content during the combustion process.

The square clamping block drives the connecting branch pipe to be positioned and connected to the drying box along the rectangular clamping groove. A driver is installed on one side of the connecting shaft. After the lithium battery foil is placed, an appropriate number of connecting branch pipes are selected according to the needs of drying. The plug-in pipe first drives the connecting main pipe to be positioned and connected to the outlet pipe. Then, the square clamping block drives the connecting branch pipe to be positioned and connected to the drying box along the rectangular clamping groove. Then, the square clamping pipe drives the connecting branch pipe to be positioned and connected to the connecting main pipe through the square clamping sleeve. In this process, the nozzle is driven by the driver to rotate and connect to the connecting branch pipe through the connecting shaft, thereby expanding the hot air ejection area.

[0014] Beneficial effects of the utility model:

[0015] 1. Open the rotating cover and place the adhesive-coated lithium battery foil in the drying oven. Then start the heating oven to burn the fuel to generate heat energy. Then, the hot air is evenly discharged through the connecting main pipe and the connecting branch pipe to volatilize and dry the adhesive on the lithium battery foil. The uniform distribution of the hot air means that the heat and air flow can evenly cover the surface of the lithium battery foil coated with adhesive, thereby ensuring that the solvent in the adhesive can be quickly and evenly evaporated and dried. This greatly improves the drying efficiency and shortens the production cycle. At the same time, the uniform hot air distribution can avoid the problem of uneven drying caused by local overheating or overcooling. In this way, the lithium battery foil adhesive can maintain a consistent drying speed and temperature during the drying process, thereby ensuring the stability and consistency of the drying quality.

[0016] 2. Pull the handle to rotate the cover through the rotating column and the drying box to open. After placing the lithium battery foil, push the handle to close the cover. During the drying process, the motor drives the rotating shaft to drive the fan blades along the rotating ring to generate wind force, thereby driving the external airflow into the drying box through the circular holes on the rotating cover, and then through the holes on the hole placement plate to reach the bottom of the drying box and then flow out from the ventilation holes, so that air circulation is formed inside the drying box, avoiding the accumulation of hot air to form fog, which leads to an increase in humidity inside the drying box. At the same time, it can ensure that the heat flow inside the drying box is more evenly distributed, avoiding the phenomenon of local overheating or overhumidity in the drying box.

[0017] 3. When a certain amount of air enters the heating box, the telescopic valve is closed through the control of the operation panel, and then the burner is started to burn the fuel and convert it into heat energy. The heat energy then enters the connecting main pipe through the outlet pipe and reaches the connecting branch pipe, and then is ejected through the nozzle. In this process, the nozzle is driven by the driver to rotate and connect with the connecting branch pipe through the connecting shaft to expand the hot air ejection area. At the same time, the oxygen content in the combustion process is measured through the action of the oxygen sensor. When the oxygen content is too low, the telescopic valve is opened through the control of the operation panel to introduce external air again. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the square clamping block 316 drives the connecting branch pipe 313 to be positioned and connected to the drying oven 1 along the rectangular clamping groove 105. Then, the square clamping pipe 312 drives the connecting branch pipe 313 to be positioned and connected to the connecting main pipe 310 through the square clamping sleeve 311.

[0029] During operation, by pulling the handle 201, the rotary cover 2 is rotated and opened with the rotating column 106 and the drying box 1, and then the hole placement plate 107 is picked up and placed inside the drying box 1 until the support column 108 touches the bottom inside the drying box 1, and then the lithium battery foil coated with adhesive is placed on the hole placement plate 107 in sequence.

[0030] After all the installation is completed, the rectangular sealing cover 301 is opened and the fuel is placed in the heating box 3. Then, the telescopic valve 303 is opened by the control of the operation panel 307 and the electromagnetic control valve 304, so that the outside air can enter the heating box 3 through the inlet pipe 302. When a certain amount of air enters the heating box 3, the telescopic valve 303 is closed by the control of the operation panel 307, and the burner is started to burn the fuel and convert it into heat energy. The heat energy then enters the connecting main pipe 310 through the outlet pipe 308 and reaches the connecting branch pipe 313, and is then ejected through the nozzle 315. During this process, the nozzle 315 is driven by the driver to rotate and connect with the connecting branch pipe 313 through the connecting shaft 314, thereby expanding the hot air ejection area. At the same time, the oxygen content in the combustion process is measured by the oxygen sensor 306.

The uniform distribution of the hot air means that the heat and air flow can evenly cover the surface of the lithium battery foil coated with the adhesive, thereby ensuring that the solvent in the adhesive can be quickly and evenly volatilized and dried, which greatly improves the drying efficiency and shortens the production cycle. At the same time, the uniform hot air distribution can avoid the problem of uneven drying caused by local overheating or overcooling. In this way, the lithium battery foil coated adhesive can maintain a consistent drying speed and temperature during the drying process, thereby ensuring the stability and consistency of the drying quality, so as to solve the problem that most existing adhesives are dried by hot air circulation during the volatilization drying process. Since the one-way hot air pipe may cause uneven hot air distribution, the drying speed of the adhesive coating surface may be inconsistent.
