Description

Technical Field

[0001] The utility model relates to the field of battery production, and particularly to a drying device and a battery sheet drying equipment. Background Art

[0002] During the battery production process, it is usually necessary to divide large-sized battery sheets into small-sized battery sheet segments. Currently, laser scribing is generally used to divide the battery sheets. During the scribing process, a coolant is required. After the scribing is completed, the coolant remains on the battery sheets, and the battery sheets need to be dried.

[0003] The existing drying device includes a heating chamber. An indirect air flow channel is provided inside the heating chamber. A plurality of air outlet holes are provided at the bottom of the heating chamber. The air outlet holes are communicated with the air outlet end of the air flow channel, and the air inlet end of the air flow channel is communicated with an external air source. The air source supplies air into the air flow channel and blows it out through the air outlet holes. A heating rod is inserted into the outer wall of the heating chamber. The outer wall of the entire heating chamber is heated by the heating rod, and the heat is then conducted to the gas inside the air flow channel, making the gas hot. The hot gas blows out from the air outlet holes and blows towards the battery sheets to dry the battery sheets.

[0004] In the existing drying device, the outer wall of the heating chamber is relatively thick, and more heat dissipated by the heating rod is lost in the outer wall of the heating chamber, that is, the heat utilization rate is relatively low, and the drying effect is poor. Summary of the Utility Model

[0005] In view of the above technical problems, the utility model provides a drying device, and its detailed technical solution is as follows:

[0006] A drying device includes a box body, at least one electric heating tube and at least one fan. The fan is installed on the first side wall of the box body. A plurality of air outlet holes are opened on the second side wall of the box body. The electric heating tube extends into the inner chamber of the box body. The fan is configured to suck outside air into the inner chamber of the box body and blow it out through the air outlet holes. The electric heating tube is configured to heat the air flowing through the inner chamber of the box body.

[0007] In this application, the electric heating tube directly heats the air flowing through the inside of the box body. The heated air blows towards the battery sheets through the air outlet holes to dry the battery sheets. The heat of the electric heating tube is directly transferred to the air inside the box body, without heat loss, and the heat utilization rate is relatively high, and the drying effect is better.

[0008] In some embodiments, the electric heating tube includes a heating tube body and a plurality of fins sleeved on the heating tube body. The plurality of fins are arranged at intervals along the length direction of the heating tube body.

[0009] In use, the heating tube body is powered on, and the heating tube body dissipates heat and transfers it to the fins. The use of the fins increases the surface area of the heating tube, enabling more heat to be transferred to the surrounding air through the fins, thereby improving the heat exchange efficiency to quickly and fully heat the air flowing through the interior of the box body.

[0010] In some embodiments, there are two electric heating tubes, and the two electric heating tubes share each fin.

[0011] By using two electric heating tubes, the air flowing through the interior of the box body can be heated more quickly and fully.

[0012] In some embodiments, the first side wall of the box body and the second side wall of the box body are arranged opposite to each other. The air outlet end of the fan faces the air outlet hole. The heating tube body is fixed on the third side wall of the box body, and the fins are vertically arranged between the first side wall and the second side wall of the box body.

[0013] By arranging the air outlet end of the fan to face the air outlet hole, the air blown out by the fan blows out from the air outlet hole at a relatively high flow rate and blows towards the battery cells to ensure the drying effect. In addition, the fins are vertically arranged between the first side wall and the second side wall of the box body, enabling the fins to fully heat the air blown out by the fan. In addition, the fins are usually relatively thin and basically do not interfere with the air flow rate.

[0014] In some embodiments, a plurality of air outlet holes are evenly opened in the area of the second side wall of the box body opposite to the electric heating tube.

[0015] By arranging the air outlet holes in the area of the second side wall of the box body opposite to the electric heating tube, the air heated by the electric heating tube can be blown out from the air outlet holes in a timely manner.

[0016] In some embodiments, there are two fans, and the two fans are arranged at intervals along the length direction of the electric heating tube.

[0017] By setting two fans, the air circulation volume is increased, the drying effect is enhanced, and the two fans are arranged along the length direction of the electric heating tube, enabling the air blown out by the fans to fully contact the electric heating tube and fully heat the air, resulting in a better drying effect.

[0018] In some embodiments, a heat insulation layer is filled in the four peripheral side walls of the box body.

[0019] By setting the heat insulation layer, the temperature inside the box body is prevented from being dissipated to the outside through the side walls of the box body, heat loss is avoided, and the drying effect is further ensured. It also has a heat insulation effect to prevent the outer wall of the box body from overheating and causing potential safety hazards.

[0020] In some embodiments, a through hole matching the size of the fan is opened on the first side wall of the box body. The fan is installed around the through hole through a mounting member, and the fan faces the inner chamber of the box body through the through hole.

[0021] The present application also provides a drying device for solar cells, including a drying apparatus and a conveyor line. The conveyor line is configured to convey solar cells in a first direction. A drying station is arranged on the conveying path of the conveyor line, and at least one drying apparatus is arranged above the conveyor line at the drying station.

[0022] The conveyor line is used to convey solar cells, so that the solar cells are successively moved to the lower part of the drying apparatus for drying, realizing an automated drying operation with relatively high efficiency.

[0023] In some embodiments, there are two drying apparatuses, and the two drying apparatuses are arranged at intervals along the first direction.

[0024] The two drying apparatuses are used to dry the solar cells to ensure that the solar cells are fully dried. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0031] As Figures 1-3 shown, the present application provides a drying apparatus, including a box body 10, at least one electric heating tube 20 and at least one fan 30. The fan 30 is installed on the first side wall 11 of the box body 10. A plurality of air outlet holes 13 are formed in the second side wall 12 of the box body 10. The electric heating tube 20 extends into the inner cavity of the box body 10. The fan 30 is configured to suck outside air into the inner cavity of the box body 10 and blow it out through the air outlet holes 13. The electric heating tube 20 is configured to heat the air flowing through the inner cavity of the box body 10.

[0032] In this application, a fan 30 is used to draw external air into the interior of the box body 10, and an electric heating tube 20 is used to directly heat the air flowing through the interior of the box body 10. The heated air is blown towards the battery cells through the air outlet holes 13 to dry the battery cells. The heat of the electric heating tube 20 is directly transferred to the air inside the box body 10, without heat loss, and the heat utilization rate is relatively high, and the drying effect is relatively good. The wind speed of the fan 30 is adjustable, and the wind speed of the fan 30 can be adjusted according to needs to meet the requirements of different scenarios.

[0033] In some embodiments, as Figure 3 shown, the electric heating tube 20 includes a heating tube body 21 and a plurality of fins 22 sleeved on the heating tube body 21, and the plurality of fins 22 are arranged at intervals along the length direction of the heating tube body 21.

[0034] In use, the heating tube body 21 is connected to an external power supply, and the heating tube body 21 dissipates heat and transfers it to the fins 22. The use of the fins 22 increases the surface area of the electric heating tube 20, so that more heat can be transferred to the surrounding air through the fins 22, thereby improving the heat exchange efficiency to quickly and fully heat the air flowing through the interior of the box body 10.

[0035] In some embodiments, as Figure 3 shown, there are two electric heating tubes 20, and the two electric heating tubes 20 share each fin 22.

[0036] By using two electric heating tubes 20, the air flowing through the interior of the box body 10 can be heated more quickly and fully.

By arranging the air outlet end of the fan 30 towards the air outlet holes 13, the air blown out by the fan 30 blows out from the air outlet holes 13 at a relatively high flow rate and blows towards the battery cells to ensure the drying effect. In addition, the fins 22 are vertically arranged between the first side wall 11 and the second side wall 12 of the box body, so that the fins can fully heat the air blown out by the fan 30. In addition, the fins 22 are usually relatively thin and basically do not interfere with the air flow rate.

[0039] In some embodiments, a plurality of air outlet holes 13 are evenly opened in the area of the second side wall 12 of the box body 10 opposite to the electric heating tube 20.

[0040] By arranging the air outlet 13 in the area of the second side wall 12 of the box body 10 opposite to the electric heating tube 20, the air heated by the electric heating tube 20 can be blown out from the air outlet 13 in time.

[0041] In some embodiments, there are two fans 30, and the two fans 30 are arranged at intervals along the length direction of the electric heating tube 20.

[0042] By setting the fans 30 to be two, the air circulation volume is increased, the drying effect is enhanced, and the two fans 30 are arranged along the length direction of the electric heating tube 20, so that the air blown out by the fans 30 can fully contact the electric heating tube 20, heat the air sufficiently, and the drying effect is better.

[0043] In some embodiments, heat insulation layers are filled in the four surrounding side walls of the box body 10.

It also has the effect of heat insulation, avoiding potential safety hazards caused by overheating of the outer wall of the box body 10.

[0045] In some embodiments, through holes matching the size of the fans 30 are formed on the first side wall 11 of the box body 10, and the fans 30 are installed around the through holes through mounting parts, and the fans 30 face the inner cavity of the box body 10 through the through holes. That is, openings are formed on the first side wall 11 of the box body 10 for the installation of the fans 30, providing a relatively simple installation method.
