Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a lithium battery manual handling device. Background Art

[0002] Lithium-ion batteries are flammable and explosive, especially when fully charged. If they experience a significant impact or are dropped during handling, causing a certain degree of deformation, they can easily experience thermal runaway, and in severe cases, they can even cause smoke and fire. During the lithium battery production process, manual handling is required to a certain extent. If handled purely manually, there is a risk of slipping or dropping the battery if the handler's hands are greasy or they are not paying attention, causing the battery to drop. For this application scenario, it is best to use a dedicated lithium battery manual handling device to assist in handling and avoid the risk of the battery dropping.

[0003] However, there is currently no good or universal device for manually transporting lithium batteries (cells) at production sites, especially for large lithium batteries such as 280AH or 350AH, so a design is needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the above-mentioned background technology and provide a device for manually transporting square aluminum shell lithium batteries (or other types of batteries) to avoid the risk of dropping the lithium batteries when manually transporting them. The device has good versatility and is easy to use.

[0005] In order to achieve the above-mentioned object, the utility model provides a lithium battery manual handling device, comprising a clamping claw and a handheld portion connected to the clamping claw;

[0006] The clamping jaws are provided in a pair and are relatively distributed;

[0007] The hand-held part includes a first connecting rod, a second connecting rod and a third connecting rod arranged opposite to each other, the first ends of the second connecting rod and the third connecting rod are provided with hinged ends and are connected to each other, the second ends of the second connecting rod and the third connecting rod are respectively fixedly connected to one of the clamping claws, the first connecting rod is provided with two hinged ends, and the non-end positions of the second connecting rod and the third connecting rod are also provided with hinged ends and are respectively hinged to the two hinged ends of the first connecting rod.

[0008] Furthermore, a clamping groove is provided on the inner side of the clamping jaw.

[0009] Furthermore, an anti-slip silica gel block is also provided in the clamping groove.

[0010] Furthermore, the hinged ends of the first connecting rod, the second connecting rod and the third connecting rod are all provided with hinge blocks, the hinge blocks are provided with hinge holes, a hinge shaft is inserted into the hinge hole, and the end of the hinge shaft is limited by a limiting nut.

[0011] Furthermore, when each hinge end is provided with at least two hinge blocks and two hinge holes, the hinge blocks are staggered and inserted when the two hinge ends are hinged.

[0012] Furthermore, the second connecting rod is hinged to the first end of the third connecting rod, and the size of the corresponding hinge shaft is smaller than the size of the hinge hole.

[0013] Furthermore, the first connecting rod, the second connecting rod, the third connecting rod, and the clamping claw are all made of stainless steel alloy.

[0014] Furthermore, outer surfaces of the first connecting rod, the second connecting rod, the third connecting rod, and the clamping jaw are provided with insulating grease, and the insulating grease is used for insulation protection.

[0015] The above solution of the utility model has the following beneficial effects:

[0016] The lithium battery manual handling device provided by the utility model can be conveniently operated by hand through the arrangement of the clamping claws and the first connecting rod, the second connecting rod, and the third connecting rod in the clamping part, so that the lithium battery is firmly clamped and lifted by the clamping claws, thereby avoiding the risk of slipping or falling out of the hands during manual handling, which may cause damage to the lithium battery. At the same time, it reduces safety hazards and improves the operating efficiency and reliability of the lithium battery production site.

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a locking connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a lithium battery manual handling device, comprising a clamping jaw 1 and a handheld portion connected to the clamping jaw 1. The clamping jaws 1 are provided in pair for clamping the lithium battery so that the lithium battery can be lifted and carried. As a preferred embodiment, a clamping groove 2 is provided on the inner side of the clamping jaw 1 in this embodiment. The clamping groove 2 matches the shape of the lithium battery, such as a square aluminum shell lithium battery, so that the lithium battery can better fit with the clamping jaw 1 when clamped, thereby improving the stability of the clamping.

[0026] It should be noted that the clamping jaw 1 in this embodiment is used to clamp the narrow surface of the lithium battery. Therefore, its width can be set to be relatively small to reduce its own weight and facilitate manual hand-held operation. As a preferred embodiment, the clamping groove 2 in this embodiment is also provided with an anti-slip silicone block 3. The anti-slip silicone block 3 has a higher coefficient of friction than other positions of the clamping jaw 1, so that the lithium battery is subjected to greater friction when clamped by the clamping jaw, further improving stability. Of course, the surface of the anti-slip silicone block 3 can also be further provided with anti-slip grooves to further increase the surface roughness and increase the friction coefficient.

[0027] At the same time Figure 2 As shown, the handheld portion includes a first connecting rod 4 and a second connecting rod 5 and a third connecting rod 6 arranged opposite to each other. The first ends of the second connecting rod 5 and the third connecting rod 6 are provided with hinged ends and are interconnected, and the second ends of the second connecting rod 5 and the third connecting rod 6 are respectively fixedly connected to one of the clamping jaws 1. The first connecting rod 4 is provided with two hinged ends, and the non-end positions of the second connecting rod 5 and the third connecting rod 6 are also provided with hinged ends, which are respectively hinged to the two hinged ends of the first connecting rod 4. Therefore, when the second connecting rod 5 and the third connecting rod 6 rotate around the hinged ends with the first connecting rod 4, the clamping jaws 1 can be moved closer or apart, thereby clamping or loosening the lithium battery.

[0028] Among them, the first connecting rod 4 is set to a "door" shape, including a horizontal cross bar and two vertical vertical rods, and the bottom end of the vertical rod is hinged to the second connecting rod 5 or the third connecting rod 6. During operation, it is necessary to move the first ends of the second connecting rod 5 and the third connecting rod 6 toward the cross bar. Based on this, in this embodiment, when the first ends of the second connecting rod 5 and the third connecting rod 6 are hinged, the size of the hinge shaft 7 is significantly smaller than the size of the hinge hole 8, so that the first ends of the second connecting rod 5 and the third connecting rod 6 can move toward the cross bar (with movable space not affected by the triangular structure), so that the second connecting rod 5 and the third connecting rod 6 rotate around the bottom end of the corresponding vertical rod. Considering that the clamping jaw 1 only needs to clamp or loosen the lithium battery without moving over a large range, this setting method can meet the requirements.

[0029] Therefore, during manual handling, the operator holds the crossbar and the second and third connecting rods 5 and 6, and lifts the second and third connecting rods 5 and 6 upwards, while the crossbar of the first connecting rod 4 remains stable under the restraint of the palm of the hand, so that the clamping jaws 1 clamp the lithium battery inward. When it is necessary to release the lithium battery, the operator first puts the lithium battery down, and then releases the second and third connecting rods 5 and 6.

[0030] As a preferred embodiment, in this embodiment, the hinged ends of the first connecting rod 4, the second connecting rod 5, and the third connecting rod 6 are all provided with hinge blocks 9, and hinge holes 8 are opened on the hinge blocks 9. At the same time, at least two hinge blocks 9 and hinge holes 8 are provided on one hinged end, so that when the two hinged ends are hinged, the hinge blocks 9 can be staggered and inserted, and then the hinge shaft 7 can be installed. Among them, limit nuts 10 can be provided at both ends of the hinge shaft 7 to limit the axial displacement of the hinge shaft 7 in the hinge hole 8 to a certain extent after installation, so that it will not fall out of the hinge hole 8.

[0031] As a preferred embodiment, the outer surfaces of the first connecting rod 4, the second connecting rod 5, the third connecting rod 6, and the clamping jaw 1 are further sprayed with insulating grease to prevent metal (stainless steel alloy is used in this embodiment) from contacting the positive and negative electrodes of the lithium battery and causing a short circuit when transporting the lithium battery. Of course, spraying the insulating grease also makes the connecting rods more convenient to hold and lift.

[0032] In other embodiments, the second connecting rod 5 or the third connecting rod 6 may be omitted, that is, only the second connecting rod 5 or the third connecting rod 6 is provided. In this case, one of the clamping jaws 1 is directly fixedly connected to the first connecting rod 4, and the first end of the second connecting rod 5 or the third connecting rod 6 is freely disposed. During operation, the second connecting rod 5 or the third connecting rod 6 is similarly moved closer to the crossbar, so that the movable clamping jaw 1 moves closer to the fixed clamping jaw 1 to clamp the lithium battery.

[0033] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
