Description

Technical Field

[0001] This invention relates to a battery baking fixture, and more particularly to a battery baking fixture suitable for baking batteries of different heights. Background Technology

[0002] With the development of new energy technologies, lithium batteries have been applied to various aspects of life. The manufacturing process of lithium batteries generally includes baking, electrolyte injection, and formation. Among these, baking is a crucial step in ensuring the quality and improving the electrical performance of lithium batteries. Currently, an oven is typically used to dry lithium batteries. Specifically, the lithium battery is placed on a battery baking fixture, which clamps it securely. A heating plate is installed on the clamping plate of the battery baking fixture. Then, the entire battery baking fixture is placed into a sealed oven, a vacuum is created inside the oven, and the heating plate heats the lithium battery to achieve the drying purpose.

[0003] However, existing battery baking fixtures have fixed heating plate areas or sizes, meaning one type of fixture is only suitable for one size of lithium battery, resulting in poor compatibility. When a lithium battery production line needs to change its design, for example, to bake short batteries, it is necessary to replace the fixture with one that is compatible with the new one, or add pads to the bottom of the fixture to raise the height of the short batteries, or replace the heating plate / clamp with one that is the right size. This increases the production cost of changing the design and is also more complicated to operate, which is not conducive to production. Summary of the Invention

[0004] The purpose of this invention is to provide a battery baking fixture that is suitable for baking batteries of different heights, is easy to operate, and has low production costs.

[0005] Another object of the present invention is to provide an oven suitable for baking batteries of different heights with low production costs.

[0006] To achieve the above objectives, the battery baking fixture provided by the present invention includes a support frame, a lifting drive mechanism, a lifting beam, and several heating plates; the heating plates are arranged laterally on the support frame to form a receiving area for accommodating batteries between two adjacent heating plates; the lower side of each heating plate is provided with a receiving groove that extends vertically and penetrates the lower edge of the heating plate; the lifting beam is arranged laterally and located below the heating plates; the lifting drive mechanism is disposed on the support frame and its output end is connected to the lifting beam to drive the lifting beam to move in the direction of entering or exiting the receiving groove.

[0007] Compared with the prior art, the present invention provides a lifting beam on the lower side of the heating plate and a receiving groove penetrating the heating plate on the lower side of the heating plate. When the battery is placed in the receiving area, the lifting beam is driven to rise or fall by a lifting drive mechanism, thereby driving the battery to rise or fall relative to the heating plate, thus achieving the purpose of adjusting the position of the battery within the receiving area. Therefore, for batteries of different heights, the lifting drive mechanism can be operated to adapt them to each other, making operation very convenient. It is also suitable for baking different types of batteries without replacing the entire fixture or the heating plate, improving machine adjustment efficiency and reducing production costs.

[0008] Preferably, the heating plate is slidably mounted on the support frame. By making the heating plate slidable, the gap size of the receiving area can be adjusted, thereby making it suitable for batteries of different thicknesses, further improving applicability and reducing production costs.

[0009] Specifically, the support frame has horizontally arranged sliding guide rails on opposite sides, and sliders are connected to opposite sides of the heating plate. The sliders are slidably mounted on the sliding guide rails, and positioning elements are provided between the sliders and the sliding guide rails to fix them relatively. By utilizing the sliding cooperation between the sliders and the sliding guide rails, the heating plate can be adjusted smoothly and stably. Furthermore, the positioning elements ensure that the heating plate is stably positioned on the sliding guide rails after adjustment, guaranteeing accurate gaps between adjacent heating plates. This makes it suitable for batteries of different thicknesses, further improving applicability and reducing production costs.

[0010] Specifically, the support frame is provided with a horizontally arranged support rail, and the heating plate is slidably supported on the support rail. This allows the heating plate to be supported even while sliding, ensuring its lateral stability.

[0011] Preferably, the lifting drive mechanism includes a pair of lead screws, a pair of nuts, a pair of lifting frames, and a connecting rod. The two lead screws are vertically pivotally connected to both ends of the support frame. The nuts are threadedly connected to the lead screws. The lifting frames are vertically slidably mounted on the support frame and fixedly connected to the nuts. Both ends of the connecting rod are connected to the lead screws via helical gear transmission pairs to transmit power. Both ends of the lifting beam are connected to the two lifting frames. Using the lead screws and nuts to drive the lifting frames up or down ensures smooth lifting and stepless adjustment of the lifting position, allowing for more precise adjustment. Furthermore, by setting a connecting rod between the two lead screws, the two lifting frames are driven synchronously by the connecting rod, ensuring that both ends of the lifting beam can rise and fall synchronously, thereby guaranteeing that the horizontal height of each battery is consistent.

[0012] Specifically, the lifting drive mechanism further includes a rotary handle or a drive motor connected to one of the lead screws.

[0013] Specifically, the lifting drive mechanism further includes a guide rod, which is disposed on the support frame and the lifting frame is slidably disposed on the guide rod. By setting the guide rod, the sliding of the lifting frame is made more stable and smooth, and at the same time, it is ensured that the opposite sides of the lifting frame can maintain the same horizontal height during lifting.

[0014] Preferably, the upper side of the heating plate is provided with a recessed groove to facilitate the placement and removal of the battery. The recessed groove allows the upper edge of the battery to protrude when placed within the receiving area, thus facilitating easy placement and removal.

[0015] An oven includes an oven body, an oven door, and a battery baking fixture. The oven body has an outwardly open receiving cavity. The battery baking fixture is slidably received in the receiving cavity and can extend out of the receiving cavity in a cantilevered state. The oven door is disposed in the oven body to open or close the receiving cavity.

[0016] Preferably, one side of the furnace door is hinged to one side of the furnace body to form a side-opening door structure. Attached Figure Description

[0024] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] like Figure 1As shown, the oven 100 of the present invention includes a battery baking clamp 1, an oven body 2, and an oven door 3. The oven body 2 has an outwardly open receiving cavity 21. The battery baking clamp 1 is arranged vertically and slidably housed within the receiving cavity 21, extending cantilevered out of the receiving cavity 21. The oven door 3 is located on the front side of the oven body 2, and one side of the oven door 3 is connected to the side of the oven body 2 via a hinge 22 to form a side-opening door structure for opening or closing the receiving cavity 21. A sealing ring 31 is provided on the inner side of the oven door 3. When the oven door 3 is closed, the sealing ring 31 elastically abuts against the perimeter of the front side of the oven body 2. A foldable connecting rod 4 is provided between the rear end of the battery baking clamp 1 and the oven body 2. The connecting rod 4 prevents the battery baking clamp 1 from excessively sliding out, ensuring safety during use.

[0026] Please see Figures 2 to 5 As shown, the battery baking fixture 1 includes a support frame 11, a lifting drive mechanism 12, a lifting beam 13, and several heating plates 14; the support frame 11 is a square frame. The heating plates 14 are arranged laterally on the support frame 11 to form a receiving area 141 for accommodating batteries between two adjacent heating plates 14. Specifically, two horizontally arranged sliding guide rails 111 are provided on opposite sides of the support frame 11, and the number of sliding guide rails 111 is two, arranged in parallel. The heating plates 14 are slidably mounted on the support frame 11 via the sliding guide rails 111. More specifically, sliders 142 are connected to opposite sides of the heating plates 14, and the sliders 142 are slidably mounted on the sliding guide rails 111. The sliding guide rails 111 are provided with a horizontal scale to facilitate adjustment of the sliding distance of the sliders 142. A positioning element (not shown in the figure) is provided between the slider 142 and the sliding guide rail 111 to fix them relatively. The positioning element is a positioning screw. By making the heating plate 14 slidably arranged, the gap size of the receiving area 141 can be adjusted, thereby making it suitable for batteries of different thicknesses, further improving applicability and reducing production costs. Furthermore, by utilizing the sliding engagement between the slider 142 and the sliding guide rail 111, the heating plate 14 can be smoothly and stably adjusted. The positioning element ensures that the heating plate 14 is stably positioned on the sliding guide rail 111 after adjustment, guaranteeing the accurate gap between adjacent heating plates 14, thus making it suitable for batteries of different thicknesses, further improving applicability and reducing production costs. The support frame 11 is provided with a horizontally arranged support guide rail 112, on which the heating plate 14 is slidably supported. This allows the heating plate 14 to be supported even while sliding, ensuring its lateral stability.

[0027] like Figure 2 , Figure 5, Figure 6 and Figure 7 As shown, the heating plate 14 has a vertically extending receiving groove 143 on its lower side, with its lower end penetrating the lower edge of the heating plate 14; the receiving groove 143 has an inverted U-shaped structure. When multiple heating plates 14 are arranged in a row, the receiving grooves 143 on each heating plate 14 are combined to form an elongated groove. The lifting beam 13 is arranged laterally and located on the lower side of the heating plate 14, corresponding to the elongated grooves one by one. The lifting drive mechanism 12 is disposed on the support frame 11 and its output end is connected to the lifting beam 13 to drive the lifting beam 13 to move in the direction of entering or exiting the receiving groove 143. Specifically, the lifting drive mechanism 12 includes a pair of lead screws 121, a pair of nuts 122, a pair of lifting frames 123, and a connecting rod 124. The two lead screws 121 are respectively vertically pivotally connected to the mounting seats at the middle of both ends of the support frame 11. The nut 122 is threadedly connected to the lead screw 121. The two lifting frames 123 are vertically slidably disposed at both ends of the horizontal axis inside the support frame 11 and are fixedly connected to the nut 122. The two ends of the connecting rod 124 are respectively connected to the lead screw 121 through a helical gear transmission pair 125 to transmit power. The two ends of the lifting beam 13 are respectively connected to the two lifting frames 123. There are two lifting beams 13, located inside the support frame 11 and on opposite sides of the connecting rod 124. By using the lead screw 121 and the nut 122 to drive the lifting frames 123 to rise or fall, the lifting can be made smooth and the lifting position can be infinitely adjusted for more precise adjustment. Moreover, by setting the connecting rod 124 between the two lead screws 121, the two lifting frames 123 are driven synchronously by the connecting rod 124, so that both ends of the lifting beam 13 can rise and fall synchronously, thereby ensuring that the horizontal height of each battery is consistent.

[0028] Please see again Figure 5 and Figure 7 The lifting drive mechanism 12 further includes a rotating handle 126 or a drive motor connected to one of the lead screws 121. In this embodiment, the lifting drive mechanism 12 drives the lead screw 121 to rotate by rotating the handle 126.

[0029] Please see again Figure 7The lifting drive mechanism 12 further includes a guide rod 127, which is mounted on the support frame 11. The lifting frame 123 is provided with a guide sleeve 1231, the side of which slides with the guide rod 127 is made of Teflon material to reduce frictional resistance. The lifting frame 123 is slidably fitted onto the guide rod 127 via the guide sleeve 1231. By providing the guide rod 127, the lifting frame 123 slides more stably and smoothly, while ensuring that the opposite sides of the lifting frame 123 maintain the same horizontal height during lifting. Additionally, the lifting drive mechanism 12 is also equipped with a height gauge to adjust the lifting height of the lifting frame 123.

[0030] For example Figure 2 and Figure 5 As shown, the upper side of the heating plate 14 is provided with a recessed groove 144 to facilitate the placement and removal of the battery. The recessed groove 144 allows the upper edge of the battery to protrude when it is placed in the receiving area 141, thus facilitating its placement and removal.

[0031] like Figure 1 In addition, the oven body 2 is also equipped with a vacuum device 23, but it is not the focus of this application. Moreover, the vacuum device 23 is a well-known technology in the field of baking technology and is well known to those skilled in the art. Therefore, it will not be described in detail here.

[0032] In summary, the working principle of the oven 100 of the present invention will be described in detail below:

[0033] During baking, the battery baking fixture 1 is first pulled out of the oven body 2. Then, according to the battery model or size, the slider 142 is moved to adjust the gap between the heating plates 14, and the slider 142 is repositioned using a positioning component. Additionally, rotating the handle 126 rotates the lead screw 121 on this side, causing the lead screw 121 to move the nut 122, which in turn moves the lifting frame 123. Simultaneously, the lead screw 121 drives the connecting rod 124 via the helical gear transmission pair 125. The connecting rod 124 drives the lead screw 121 on the other side to rotate synchronously, causing both lifting frames 123 to rise and fall synchronously. As the two lifting frames 123 rise and fall, they also raise and lower the lifting beam 13, thereby adjusting the height of the lifting beam 13 so that the battery, supported by the lifting beam 13, is positioned in the middle of the receiving area 141. This allows the battery baking fixture 1 to extend in a cantilevered state. Finally, the battery is placed in the receiving area 141. At this point, the battery baking fixture 1, filled with batteries, can be pushed into the oven body 2, and then the oven door 3 can be closed. Afterwards, the vacuum device evacuates the oven body 2, while the heating plate 14 heats the batteries to achieve baking.

[0034] Compared with the prior art, the present invention provides a lifting beam 13 on the lower side of the heating plate 14 and a receiving groove 143 penetrating the heating plate 14 on the lower side of the heating plate 14. When the battery is placed in the receiving area 141, the lifting beam 13 is driven to rise or fall by the lifting drive mechanism 12, thereby driving the battery to rise or fall relative to the heating plate 14, thus achieving the purpose of adjusting the position of the battery within the receiving area. Therefore, for batteries of different heights, the lifting drive mechanism 12 can be operated to adapt them to each other. Thus, it is very convenient to operate and suitable for baking different types of batteries without replacing the entire fixture or the heating plate 14, improving the efficiency of machine adjustment and reducing production costs.

[0035] The structure of the heating plate 14 involved in the battery baking fixture 1 of the present invention is well known to those skilled in the art, and will not be described in detail here.

[0036] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
