[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In the current lithium battery production process, the cell trays inevitably generate foreign matter such as dust, metal shavings, plastic particles, and electrolyte during use.

[0004] In existing technologies, high-pressure water guns or brushes are commonly used to clean the battery cells. After cleaning, the trays are left to air dry, and the drying effect depends entirely on the weather. In summer, when the temperature is high, the drying effect is good, but in winter, the low temperature environment leads to poor drying effect, which prolongs the drying time of the trays and thus seriously affects the turnover and utilization rate of the trays. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a rapid drying device for battery cell trays. A rotating tray platform and a tray positioning device are used to fix the trays on the platform. Centrifugal force from the rotation removes some of the moisture from the tray surface. A drying chamber is installed outside the tray platform, containing heating rods and an electric fan.

[0032] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a rapid drying device for battery cell trays, such as... Figure 1 , Figure 4 As shown, the system includes a pallet base 1, which is rotatably connected to a pallet platform 3. Specifically, one end of a connecting rod 2 is fixedly mounted at the center of the bottom of the pallet platform 3, and the other end of the connecting rod 2 is rotatably connected to the center of the pallet base 1. A pulley is fixedly mounted on the body of the connecting rod 2. A first drive motor 6 is mounted on one side of the pallet base 1, and a pulley is also mounted at the output end of the first drive motor 6. It can be understood that the pulley at the output end of the first drive motor 6 is connected to the pulley on the body of the connecting rod 2 via a transmission belt 5. Starting the first drive motor 6 can drive the connecting rod 2 and the pallet platform 3 to rotate relative to the pallet base 1. In this embodiment, the pallet base 1 and the pallet platform 3 are disc-shaped.

[0034] In some embodiments, a bearing mounting hole can be provided at the center of the tray base 1 to fix the outer ring of the bearing, and then the inner ring of the bearing can be fixed at the end of the connecting rod 2 away from the tray platform 3, so that the connecting rod 2 can rotate relative to the tray base 1. It can be understood that placing the tray on the tray platform 3 and starting the first drive motor 6 to make the tray platform 3 rotate with the tray can cause some of the water on the tray to be thrown out by the outward centrifugal force.

[0035] like Figure 4 , Figure 6 As shown, a pallet positioning device 4 is provided on the pallet platform 3 to fix the pallet and prevent the pallet from being thrown out by the rotational force when the pallet platform rotates. Figure 7 , Figure 8As shown, the pallet positioning device 4 includes four identical, hollow positioning iron boxes 4-2. One side wall of each positioning iron box 4-2 has a positioning pin through-hole, and the opposite side wall has a rope through-hole. A tapered positioning pin 4-1 passes through the positioning pin through-hole, with its tail end positioned inside the positioning iron box. The tail end of the tapered positioning pin 4-1 is fixedly connected to a rope 4-4, which passes through the rope through-hole and connects to the second drive motor 4-5.

[0036] like Figure 7 , Figure 8 As shown, a spring 4-3 is also provided inside the positioning iron box 4-2. One end of the spring 4-3 abuts against the side wall of the positioning iron box with a rope through hole, and the other end abuts against the tail end of the conical positioning pin 4-1. The rope 4-4 passes through the cylindrical hollow interior of the spring 4-3.

[0037] like Figure 7 As shown, several adjusting screw holes are provided on the top surface of the pallet platform 3. The adjusting screw holes are distributed in a cross shape with the center of the top surface of the pallet platform 3 as the midpoint, and there are four groups in total. Each group has several pairs of adjusting screw holes. The midline of the line connecting each pair of adjusting screw holes passes through the center of the top surface of the pallet platform 3, which is the radius line of the top surface of the pallet platform 3. The distance between each pair of adjusting screw holes and the adjacent pair of adjusting screw holes is equal.

[0038] like Figure 7 As shown, the four corners of the bottom of the positioning box 4-2 are fixed with connecting buckles. Align the four connecting buckles with two pairs of adjacent adjusting screw holes in the same group, and insert the fixing bolts to fix the positioning box 4-2 to the tray platform. It can be understood that the connecting buckles have bolt through holes of the same size as the adjusting screw holes.

[0039] like Figure 7 As shown, the second drive motor 4-5 is fixed at the center of the top surface of the pallet platform 3, and a drum is provided at the output end of the second drive motor 4-5; the rope 4-4 of each positioning iron box 4-2 is fixedly set on the drum. When the second drive motor rotates forward, it drives the drum to wind the rope 4-4. When the second drive motor rotates in reverse, it drives the drum to release the rope 4-4.

[0040] It is important to note that the four positioning iron boxes 4-2 should be fixed to the tray platform according to the inner wall dimensions of the tray to be dried. In this embodiment, the tray is a square open tray, with positioning holes provided on the center line of the inner wall of the tray near the opening. The tray must be placed with the opening facing the tray platform, i.e., facing downwards onto the tray platform. The four positioning iron boxes 4-2 are then fixed to the corresponding adjusting screw holes on the tray platform according to the inner wall dimensions of the tray. It is understood that placing the tray downwards onto the tray platform allows water to flow downwards under gravity.

[0041] The second drive motor 4-5 in the middle of the pallet platform 3 rotates forward, winding the four ropes around the drum, causing the ropes to move towards the positioning iron box 4-2 with the conical positioning pins. Then, the pallet is placed on the pallet platform 3 with the opening facing down, so that the inner wall of the pallet contacts the positioning iron box at the corresponding position. Then, the second drive motor 4-5 reverses to release the ropes. Under the action of the spring, the conical positioning pin is inserted into the positioning hole in the inner wall of the pallet by the spring force, fixing the pallet.

[0042] In this embodiment, one of the purposes of rotating the pallet is to shake off some of the surface moisture. Therefore, the rotation speed of the pallet platform should not be too fast, because too fast a rotation speed will also lead to a large centrifugal force, which will cause the pallet and the pallet positioning device to be subjected to excessive force, thereby damaging the pallet and the pallet positioning device. The rotation speed is set to 100-150 revolutions per minute.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, it also includes a drying chamber, which is located outside the pallet base 1 and the pallet platform 3, covering the pallet base 1 and the pallet platform 3. The first drive motor 6 is located outside the drying chamber. The drying chamber includes four corner columns, a top roof frame 11, and side wall insulation composite panels 7, a top plate 12, insulation composite door panels 13, and a rear wall insulation composite panel 14.

[0044] Specifically, the four corner columns and the top roof frame 11 adopt a steel pipe structure, and the top of the four corner columns are fixedly connected to the top roof frame 11; first, the rear wall insulation composite panel 14 is installed, and the rear wall insulation composite panel 14 is fixed between the two corner columns by rivets or other means, and then two side wall insulation composite panels 7 are installed, which are perpendicular to the rear wall insulation composite panel 14; on the side facing away from the rear wall insulation composite panel 14, there are two corner columns that are not connected to the rear wall insulation composite panel 14, one of which is equipped with a multi-link 15, and the other corner column is equipped with a locking buckle 16; the top plate 12 is fixedly installed on the top roof frame 11.

[0045] Understandably, hinge 15 connects to one end of the insulated composite door panel 13, and a latch 16 is also provided on the other end of the insulated composite door panel 13, into which a pin 17 can be inserted. By pulling out the pin 17, the insulated composite door panel 13 can be opened, allowing entry into the drying oven.

[0046] In this embodiment, the rear wall insulation composite panel 14 and the side wall insulation composite panel 7 of the drying oven need to be a certain distance from the ground, so that the bottom of the drying oven is higher than the top surface of the tray base 1 and lower than the bottom of the tray platform 3. This design allows air inside the drying oven to circulate with the outside air through the reserved space at the bottom. It is understood that the length and width dimensions of the tray base 1 and the tray platform 3 are smaller than the dimensions of the side wall insulation composite panel 7, the insulation composite door panel 13, and the rear wall insulation composite panel 14, so that the drying oven can completely enclose the tray base 1 and the tray platform 3.

[0047] like Figure 4 , Figure 5 , Figure 6 As shown, a top cross support 9 is installed at the bottom of the top roof frame 11. Inside the drying chamber, heating rods 8 are installed on both the top cross support 9 and the side walls of the drying chamber. An electric fan 10 is installed on the top roof frame 11. It is understood that placing the tray on the tray platform 3, closing the insulated composite door panel 13, and turning on the heating rods 8 generates a sufficiently high temperature inside the drying chamber, causing the remaining moisture on the tray surface to evaporate. Although there is ventilation space at the bottom of the drying chamber, the insulated side walls and door panel also provide good insulation, evaporating the moisture from the tray. Turning on the electric fan 10 circulates the air inside the drying chamber. Due to the ventilation space at the bottom of the drying chamber, hot air flows from top to bottom through the tray and then out of the drying chamber, further accelerating the evaporation of residual moisture on the tray surface. It is also understood that the tray rotates under the influence of the tray platform, ensuring that all surfaces are heated evenly and uniformly by the flowing hot air, causing moisture evaporation.

[0048] like Figure 5 As shown, the heating rods 8 are connected in series via cables 19; Figure 1 As shown, a control box 18 is installed outside the drying oven. The electric fan 10 and the heating rod 8 are both connected to the control box 18 via cables 19. Multiple switches are installed inside the control box 18, namely a first drive motor switch, a second drive motor switch, and an electric fan / heating rod switch. It can be understood that the second drive motor switch controls the second drive motor to rotate forward or reverse, or to turn it off; the electric fan / heating rod switch is used to turn the heating rod 8 and the electric fan 10 on or off.

[0049] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
