Description

Technical Field

[0001] The utility model generally relates to the technical field of lithium batteries, and more specifically relates to a lithium battery baking device. Background Art

[0002] Baking is an essential step in the production process of lithium batteries. Since the electrolyte of lithium batteries is an organic substance that does not contain water molecules, the presence of water is extremely harmful to the battery and can easily cause the battery to heat up and explode. Therefore, lithium batteries must be vacuum baked to remove moisture before pre-sealing.

[0003] The existing baking method involves placing lithium batteries on a battery tray and then placing the tray in a baking oven for baking. This method presents the following problems: First, the tray / clamp must be frequently taken back and forth from the baking oven using specialized tools such as a forklift and placed on a buffer platform for lithium battery placement. This process does not eliminate the need for a robot or module to place the lithium batteries into the tray / clamp. Second, each time the fixture / tray is taken in and out of the oven, the connecting wires between the fixture and the oven must be frequently connected and disconnected, resulting in limited operating space and low efficiency.

[0004] In view of this, there is an urgent need to provide a lithium battery baking device to solve the problem. Utility Model Content

[0010] Preferably, green fiberglass is provided on the inner side of the sliding groove, and the green fiberglass is used to isolate the sliding strip from the sliding groove to prevent direct contact between the two.

[0011] Preferably, the folding wire groove includes a first fixed seat, a second fixed seat, a movable seat, a first rotating member, and a second rotating member. The two ends of the first rotating member are respectively hinged to the first fixed seat and the first end of the movable seat, and the two ends of the second rotating member are respectively hinged to the second fixed seat and the second end of the movable seat. The first fixed seat is fixedly connected to the fixing frame, the second fixed seat is fixedly connected to the drawer - type tray, and the included angle between the first rotating member and the second rotating member is greater than 0 and not more than 180 degrees.

[0021] Embodiments will now be described with reference to the accompanying drawings. It should be understood that, for simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated in the drawings to indicate corresponding or similar elements. Additionally, the present utility model sets forth many specific details in order to provide a thorough understanding of the embodiments described herein. However, those of ordinary skill in the art will understand that the embodiments described herein may be practiced without these specific details. In other instances, well - known methods, procedures, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be regarded as limiting the scope of the embodiments described herein.

[0022] According to an embodiment of the present utility model, a lithium - battery baking device is provided, including: a baking box body, the baking box body having at least one chamber, at least two drawer - type trays 11 arranged vertically in the chamber, each drawer - type tray 11 being slidably connected to a fixed frame 12 provided in the chamber, each drawer - type tray 11 having a plurality of accommodation positions for placing lithium batteries, the bottom of each drawer - type tray 11 being a heating plate, and a folding wire groove being provided between one side of each drawer - type tray 11 close to the back of the chamber and the fixed frame 12, and wires for electrically connecting the heating plate being arranged in the folding wire groove.

[0023] The fixed frame 12 in the above - mentioned embodiment can be welded using profiles, and the heating plate can be an aluminum plate with a thickness of 7 cm.

[0024] A first limit block 21 for preventing its overturning is provided on one side of the fixed frame 12 close to the back of the chamber, and the fixed frame 12 is bolt - connected to the chamber on one side close to the chamber entrance. The bottom profile of the fixed frame 12 can extend slightly, and the extended part is placed directly below the first limit block 21 so that the upward displacement of the extended part is restricted by the first limit block 21.

[0025] In one embodiment, slide bars are provided on the left and right sides of the drawer tray 11, and chutes for the slide bars to slide are provided on the left and right sides of the fixed frame 12. A second limiting block 31 is further included, and the second limiting block 31 is used to limit the relative position of the drawer tray 11 and the fixed frame 12 in the horizontal direction to prevent the drawer tray 11 from disengaging from the chute. The second limiting block 31 can be set according to the actual situation as long as the accommodating position of the drawer tray 11 is fully extended out of the chamber. Correspondingly, a protrusion or a clamping block for being limited by the second limiting block 31 can be provided on the drawer tray 11.

[0026] To prevent the slide bars from directly contacting and rubbing against the chutes to generate metal debris, green fiberglass can be provided on the inner side of the chutes, and the green fiberglass is used to isolate the slide bars from the chutes to prevent direct contact between the two.

[0027] In one embodiment, the foldable wire trough can include a first fixed seat 51, a second fixed seat 52, a movable seat 53, a first rotating member 54, and a second rotating member 55. Two ends of the first rotating member 54 are respectively hinged to the first fixed seat 51 and the first end of the movable seat 53, and two ends of the second rotating member 55 are respectively hinged to the second fixed seat 52 and the second end of the movable seat 53. The first fixed seat 51 is fixedly connected to the fixed frame 12, the second fixed seat 52 is fixedly connected to the drawer tray 11, and the included angle between the first rotating member 54 and the second rotating member 55 is greater than 0 and does not exceed 180 degrees. When the drawer tray 11 moves relative to the fixed frame 12, the foldable wire trough is in a V-shaped state. During the process of its opening and retracting, the included angle between the first rotating member 54 and the second rotating member 55 continuously changes. During this process, the wire will not be pulled due to the opening and retracting of the foldable wire trough, and the wire can be protected from being broken.

[0028] In the above embodiment, two retaining pieces 61 are provided on the outer side of the movable seat 53, and the retaining pieces 61 are used to limit the rotation of the first rotating member 54 and the second rotating member 55 within a preset angle range. In fact, the included angle between the first rotating member 54 and the second rotating member 55 of the foldable wire trough can also be limited by controlling the relative position of the drawer tray 11 and the fixed frame 12. The retaining pieces 61 can play a further limiting role to prevent the included angle between the first rotating member 54 and the second rotating member 55 from reaching 180 degrees during the changing process.

[0029] In some other embodiments, a lock 71 is further included. When the drawer tray 11 is located in the chamber, the lock 71 is used to limit the displacement of the drawer tray 11 to prevent it from sliding out of the chamber. For example, after the drawer tray 11 is pushed into the chamber of the baking box body, the lock 71 is toggled to limit the displacement of the drawer tray 11 to prevent it from sliding out of the chamber.
