Description

Technical Field

[0001] The utility model belongs to the technical field of battery processing, and in particular relates to a crane clamp structure, a clamping device and battery formation processing equipment. Background Art

[0002] The battery formation process is a crucial step in battery production and a major factor influencing battery quality. Battery formation involves the initial low-current charging of newly manufactured batteries, which forms a SEI film on the negative electrode surface. This SEI film significantly impacts battery performance. During formation, the battery cells are held in place by clips on the formation tray. These clips are electrically connected to the PCB, and require repeated tightening and loosening.

[0003] However, some existing overhead crane clamping structures clamp the battery cell in the middle of the airbag. The battery cell inevitably generates gas during the formation process, especially when producing cells longer than 100mm, causing the airbag to deform and collapse. This collapse is mostly concentrated in the middle of the airbag, which means the overhead crane clamps the battery cell only at the very top of the airbag. This results in poor clamping stability, causing the cell to tilt and fall, potentially causing the cell to fall or become crushed and catch fire, significantly reducing safety.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or multiple situations exist.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0028] The following is combined with Figures 1 to 4 The present invention is further described in detail, but is not intended to limit the present invention.

[0029] like Figure 1 As shown, in one embodiment of the present invention, the overhead crane clamp structure includes a connecting portion 3, a supporting portion 1 and at least two clamping portions 2; the connecting portion 3 is connected to one side end of the supporting portion 1; all the clamping portions 2 are connected side by side to the other side end of the supporting portion 1; and an air avoidance groove 4 is provided between adjacent clamping portions 2 and the supporting portion 1.

[0030] The technical solution of the utility model adopts a design with an air avoidance groove in the middle and clamping parts on both sides, which can avoid clamping the middle position of the air bag in the battery cell during the clamping process, and through the stable clamping effect of the clamping parts on both sides, the clamping stability of the battery cell can be further improved, avoiding the battery cell from falling and being damaged; thereby improving the stability and safety of use.

[0031] Specifically, in some embodiments, Figure 1 and 2 As shown, the clamping portion 2 includes a guide segment 21 and a clamping segment 22, which are arranged sequentially from the clamping portion 2 toward the support portion 1. This structure prevents the clamping portion from excessively impacting the side surface of the airbag by the sliding guidance of the guide segment at one end, thereby ensuring smooth clamping. The clamping action of the central clamping segment further enhances the stability of the airbag clamping.

[0032] Specifically, in some embodiments, Figure 2 As shown, one side surface of the clamping section 22 is provided with a clamping straight surface 221; one side surface of the guide section 21 is provided with a guiding inclined surface 211; and one end of the guiding inclined surface 211 is connected to one end of the clamping straight surface 221. In other words, the inclined guiding effect of the outer end guiding inclined surface 211 and the clamping effect of the connected clamping straight surface 221 can improve the smoothness of the airbag's movement and enhance its efficiency.

[0033] Specifically, in some embodiments, Figure 2 As shown, the thickness of the guide section 21 on the side closest to the clamping section 22 is greater than the thickness of the guide section 21 on the side away from the clamping section 22. In other words, the thickness of the guide section 21 gradually increases from the outside toward the clamping section 22, effectively saving material investment. At the same time, it can also gradually improve the clamping stability of the airbag during the process of guiding from the outside to the inside, thereby improving safety and stability in use.

[0034] Specifically, in some embodiments, Figure 2 As shown, the angle β between the guide slope 211 and the horizontal plane is β; β satisfies the following: 3°≤β≤7°. That is, β can be 3°, 3.5°, 4°, 4.5°, 5°, etc. It is preferably 4.5°. This structure, with a relatively small angle within an appropriate range, can prevent the airbag from tilting and ensure the orderly guidance of the airbag.

[0035] Specifically, in some embodiments, Figure 2 As shown, the relationship between the thickness h1 at each location on the guide slope 211 and the thickness h2 at each location on the clamping straight surface 221 satisfies: h2 ≥ h1. This structure, by maintaining an appropriate thickness range, can prevent the airbag from warping, while also ensuring orderly airbag guidance and stable clamping.

[0036] Specifically, in some embodiments, Figure 1 and 2 As shown, a limiting slope 11 is provided on one side surface of the support portion 1; the limiting slope 11 is connected to the clamping straight surface 221; the limiting slope 11 is inclined outward from the surface of the support portion 1; and a limiting groove 24 is provided between the limiting slope 11 and the clamping straight surface 221. In other words, the outward-tilted and inclined limiting slope 11 can prevent the airbag from continuing to move toward the connecting block 3 or the support block 1, thereby improving the limiting efficiency; and the limiting groove 24 with the function of limiting space can further improve the limiting effect on the topmost airbag, ensure the clamping position, and avoid damage caused by collision between the clamping portion 2 and the battery cell body. Among them, the support portion 1 uses a support block with a right-angled trapezoidal cross-section.

[0037] Specifically, in some embodiments, Figure 2As shown, the angle α between the limiting inclined surface 11 and the horizontal plane is α; α satisfies the following: 8° ≤ α ≤ 18°. That is, α can be 9°, 9.5°, 10°, 11°, 15°, etc., with 15° being the preferred angle. This structure, with its relatively small angle and appropriate range, avoids excessive abutment and limiting of the airbag, while also ensuring stable clamping and placement of the airbag and extending its service life.

[0038] Specifically, in some embodiments, Figure 2 As shown, the relationship between the thickness h3 at each location on the limiting inclined surface 11 and the thickness h2 at each location on the clamping straight surface 221 satisfies: h3 ≥ h2. This structure, through the appropriate thickness range, further avoids excessive abutment and limiting of the airbag, while also ensuring the stability of the airbag's clamping and placement, extending its service life.

[0039] Wherein, in some embodiments, Figure 1 and 2 As shown, the side surface of the connecting portion 3 is provided with at least one mounting hole 31. The connecting portion 3 can be a square connecting block or an irregularly shaped connecting block; the mounting hole 31 is used for connecting the swing drive motor or cylinder.

[0040] The present invention also provides a clamping device, such as Figure 3 and 4 As shown, the clamping device includes at least two side-by-side overhead crane clamp bodies; a clamping cavity 26 and a guide cavity 27 are provided between two adjacent overhead crane clamp bodies; the guide cavity 27 and the clamping cavity 26 are arranged sequentially from the clamping portion 2 toward the support portion 1; and the clamping cavity 26 is used to receive the air bag 51 in the battery cell body 5. The specific structure of the overhead crane clamp structure is similar to that of the above-mentioned embodiments. Since this clamping device utilizes all the technical solutions of all of the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be further elaborated here.

[0041] Among them, such as Figure 2 and 3 As shown, the clamping cavity 26 is formed between the two limiting grooves 24 in the two adjacent overhead crane clamp structures; the guide cavity 27 is formed between the two guiding inclined surfaces 211 in the two adjacent overhead crane clamp structures; and the width of the guide cavity 27 is greater than the width of the clamping cavity 26; to ensure the convenience of the air bag entering the clamping cavity 26 and to ensure the stability of the air bag 51 when assembled to the clamping cavity 26.

[0042] The present utility model also proposes a battery formation processing equipment, which includes a clamping device. The specific structure of the clamping device refers to the above embodiment.
