Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a tooling for a battery casing lower part. Background Technology

[0002] During the process of unloading car battery cases, it is necessary to manually hang the chain of an electric hoist into the battery case lifting port, then lift the electric hoist to move the battery case out of the production line material frame and move it to the top of the material rack. After manually flipping the battery case over, it is placed into the material rack. The whole process wastes a lot of manpower and takes a long time. Utility Model Content

[0003] This application provides a battery casing unloading tooling, which is simple and convenient to operate, and can achieve rapid unloading, saving manpower and reducing operation time.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides a battery casing lowering fixture, including a fixed base, a crossbeam, and a suction cup. The crossbeam is rotatably mounted on the fixed base. The suction cup includes a body portion and a flexible portion. The body portion has a negative pressure chamber. Along the thickness direction of the body portion, the body portion has a first side and a second side disposed opposite to each other. The first side is connected to the crossbeam. The second side has a first through hole communicating with the negative pressure chamber. The flexible portion is disposed on the second side. The flexible portion is adapted to flexibly fit against the battery casing when a negative pressure is generated in the negative pressure chamber.

[0006] The battery casing unloading fixture proposed in this application uses a negative pressure chamber in the main body to press a flexible part against the surface of the battery casing when negative pressure is generated. The flexible part can fill the grooves on the surface of the battery casing, better encapsulating and adsorbing the battery casing, increasing the contact area between the suction cup and the battery casing, and thus improving the stability of the suction cup adsorbing the battery casing. The suction cup adsorbs the battery casing for unloading, and then the crossbeam is rotated to adjust the angle of the battery casing, placing it on the material rack. The entire operation is simple and convenient, reducing manpower and operation time.

[0007] Optionally, the flexible part has a through hole that communicates with the first through hole.

[0008] In the above scheme, the negative pressure chamber of the main body is connected to the through hole through the first through hole, so that the gas between the battery case and the main body can be extracted through the through hole and the first through hole, thereby making the suction cup stick to the battery case.

[0009] Optionally, there are multiple through holes and the first via hole, and each through hole is disposed opposite to the corresponding first via hole along the thickness direction of the body portion.

[0010] In the above scheme, multiple through holes and multiple first through holes are set one-to-one, which can generate negative pressure more quickly and shorten the operation time.

[0011] Optionally, there are multiple suction cups, which are spaced apart along the length of the crossbeam.

[0012] In the above scheme, multiple suction cups are spaced apart along the length of the crossbeam. When the multiple suction cups adsorb the battery case, the forces acting on the battery case are balanced, which improves the stability of the lower part of the battery case.

[0013] Optionally, the plurality of suction cups includes a first suction cup and a second suction cup, wherein the length direction of the first suction cup and the length direction of the second suction cup both intersect the length direction of the crossbeam.

[0014] The above solution allows for balanced force distribution along both the length and width of the battery casing, thereby improving the stability of the lower component of the battery casing.

[0015] Optionally, the plurality of suction cups may further include a third suction cup, which is disposed between the first suction cup and the second suction cup along the length direction of the crossbeam, and the angle between the length direction of the third suction cup and the length direction of the crossbeam is adjustable.

[0016] In the above scheme, the angle between the length direction of the third suction cup and the length direction of the crossbeam is adjustable so that the third suction cup can be adapted to battery cases of different models or structures.

[0017] Optionally, the third suction cup is rotatably disposed on the crossbeam, and the pivot axis of the third suction cup is parallel to the thickness direction of the third suction cup.

[0018] In the above scheme, the third suction cup is rotatably mounted on the crossbeam, thereby making the angle between the length direction of the third suction cup and the length direction of the crossbeam adjustable to suit different models and structures of battery cases.

[0019] Optionally, the flexible part is foam.

[0020] In the above solution, because foam has good flexibility, it can completely fill the uneven surface of the battery case and effectively wrap and adsorb the battery case, thereby increasing the contact area between the suction cup and the battery case and thus improving the stability of the suction cup adsorbing the battery case.

[0021] Optionally, the battery casing lower part tooling also includes a flipping mechanism, which includes a flipping cylinder and a linkage. Along the length of the crossbeam, one side of the linkage is fixedly connected to the crossbeam, and the other side is rotatably connected to the fixed seat. The fixed end of the flipping cylinder is connected to the fixed seat, and the driving end of the flipping cylinder is connected to the linkage to drive the linkage to rotate the crossbeam relative to the fixed seat.

[0022] In the above scheme, the flipping cylinder drives the linkage to rotate relative to the fixed base. The rotation of the linkage drives the crossbeam to rotate, and the crossbeam rotates with the suction cup, thereby realizing the flipping of the battery case.

[0023] Optionally, the linkage part is provided with a first limiting part, and the fixed base is provided with a second limiting part. When the linkage part rotates to a preset angle, the first limiting part and the second limiting part abut against each other to restrict the linkage part from continuing to rotate.

[0024] In the above scheme, the flipping cylinder drives the linkage to rotate relative to the fixed seat. The rotation of the linkage drives the crossbeam to rotate. When the linkage rotates to a predetermined angle, the first limiting part and the second limiting part abut against each other, restricting the linkage to continue rotating, thereby limiting the rotation angle of the crossbeam.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0046] During the process of unloading car battery casings, it is necessary to manually hang the chain of an electric hoist onto the battery casing hoisting port, then lift the electric hoist to move the battery casing out of the production line material frame and move it to the top of the material rack. After manually flipping the battery casing over, multiple workers work together to lift the battery casing and place it into the material rack. The whole process wastes a lot of manpower and takes a long time.

[0047] Therefore, this application requires a battery casing unloading tooling that is simple to operate and saves manpower and operation time.

[0048] This application provides a tooling for a lower part of a battery casing, as shown in the following embodiments. Figures 1 to 3 The fixture for lowering the battery casing 6 includes a fixed base 1, a crossbeam 2, and a suction cup 3. The crossbeam 2 is rotatably mounted on the fixed base 1. The suction cup 3 includes a body portion 31 and a flexible portion 32. The body portion 31 has a negative pressure chamber. Along the thickness direction of the body portion 31, the body portion 31 has a first side 311 and a second side 312 arranged opposite to each other. The first side 311 is connected to the crossbeam 2. The second side 312 has a first through hole 313 communicating with the negative pressure chamber. The flexible portion 32 is disposed on the second side 312. The flexible portion 32 is adapted to flexibly adhere to the battery casing 6 when a negative pressure is generated in the negative pressure chamber. The flexible portion 32 flexibly adhering to the battery casing 6 means that the flexible portion 32 can be squeezed and deformed to fill the grooves on the surface of the battery casing 6, thus better wrapping and adsorbing the battery casing 6. In other words, even if the surface of the battery casing 6 has an uneven structure, the suction cup 3 with the flexible portion 32 can still adsorb the battery casing 6, thereby realizing the lowering of the battery casing 6.

[0049] The battery casing 6 lowering fixture proposed in this embodiment has a flexible part 32 adapted to contact the battery casing 6. When the battery casing 6 needs to be lowered, the crossbeam 2 is rotated until the flexible part 32 of the suction cup 3 is in contact with the battery casing 6. The negative pressure chamber of the main body 31 generates a negative pressure, pressing the flexible part 32 against the battery casing 6. At this time, the suction cup 3 adsorbs the battery casing 6, and the battery casing 6 is lowered. Then, the angle of the battery casing 6 is adjusted by rotating the crossbeam 2, and the battery casing 6 is placed on the material rack. The first through hole 313 is used to connect the negative pressure chamber to the outside. When the gas between the battery casing 6 and the main body 31 is extracted, the negative pressure chamber generates a negative pressure, and the flexible part 32 is squeezed onto the battery casing 6, and the suction cup 3 adsorbs the battery casing 6. When the negative pressure chamber of the main body 31 generates negative pressure, it presses the flexible part 32 onto the surface of the battery shell 6. The flexible part 32 can fill the groove on the surface of the battery shell 6, which can better wrap and adsorb the battery shell 6, increase the contact area between the suction cup 3 and the battery shell 6, thereby improving the stability of the suction cup 3 adsorbing the battery shell 6. Moreover, the whole operation process is simple and reduces manpower and operation time.

[0050] For example, the flexible portion 32 may be arranged around the edge of the second side 312 or may cover the entire plane of the second side 312.

[0051] Optionally, refer to Figure 3 and Figure 4 The flexible part 32 has a through hole 321, which is connected to the first through hole 313. The negative pressure chamber of the main body 31 is connected to the through hole 321 through the first through hole 313, so that the gas between the battery case 6 and the main body 31 can be extracted through the through hole 321 and the first through hole 313. When the negative pressure chamber generates negative pressure, the flexible part 32 is squeezed and adhered to the uneven surface of the battery case 6.

[0052] Optionally, refer to Figure 3 and Figure 4 There are multiple through holes 321 and multiple first through holes 313, arranged along the thickness direction of the body 31, with each through hole 321 opposite to the corresponding first through hole 313. The one-to-one correspondence between multiple through holes 321 and multiple first through holes 321 can generate negative pressure more quickly, shorten the operation time, and maximize the adsorption force of the suction cup 3 on the battery case 6.

[0053] Optionally, refer to Figure 1 and Figure 2 Multiple suction cups 3 are arranged at intervals along the length X of the crossbeam 2. When the multiple suction cups 3 are arranged at intervals along the length X of the crossbeam 2, the forces acting on the battery case 6 are balanced, which improves the stability of the battery case 6 and reduces damage to the battery case 6 or the extension of operation time due to the instability of the battery case 6.

[0054] Optionally, refer to Figure 1 The multiple suction cups 3 include a first suction cup 33 and a second suction cup 34. The length direction Y of the first suction cup 33 and the length direction of the second suction cup 34 both intersect the length direction X of the crossbeam 2, so that the battery case 6 is subjected to balanced force in the length and width directions, thereby improving the stability of the lower part of the battery case 6.

[0055] Optionally, refer to Figure 1 The multiple suction cups 3 also include a third suction cup 35, which is positioned between the first suction cup 33 and the second suction cup 34 along the length X of the crossbeam 2. The angle between the length direction of the third suction cup 35 and the length direction X of the crossbeam 2 is adjustable. This adjustable angle allows the third suction cup 35 to adapt to battery cases 6 of different models or structures. If the surface of the battery case 6 has holes or other obstacles that affect the adsorption of the third suction cup 35, the angle of the length direction of the third suction cup 35 relative to the length direction X of the crossbeam 2 can be adjusted to change the position of the third suction cup 35 adsorbing the battery case 6. This further ensures the stability of the suction force adsorbing the battery case 6, thereby improving the stability of the battery case 6.

[0056] Optionally, the third suction cup 35 is rotatably mounted on the crossbeam 2, and the pivot axis Z of the third suction cup 35 is parallel to the thickness direction of the third suction cup 35. The third suction cup 35 is rotatably mounted on the crossbeam 2, thereby making the angle between the length direction of the third suction cup 35 and the length direction X of the crossbeam 2 adjustable to suit different models and structures of battery cases 6.

[0057] Optionally, the flexible part 32 is foam, such as sponge made of ethylene-propylene copolymer (EPDM) or cross-linked polyethylene (XPE) foam. Because foam has good flexibility, it can completely fill the uneven surface of the battery case 6, effectively wrapping and adsorbing the battery case 6, thereby increasing the contact area between the suction cup and the battery case 6, and thus improving the stability of the suction cup adsorbing the battery case 6.

[0058] Optionally, refer to Figure 5 and Figure 6 The lower fixture for the battery casing 6 also includes a flipping mechanism 4. The flipping mechanism 4 includes a flipping cylinder 41 and a linkage 42. Along the length X of the crossbeam 2, one side of the linkage 42 is fixedly connected to the crossbeam 2, and the other side is rotatably connected to the fixed base 1. The fixed end of the flipping cylinder 41 is connected to the fixed base 1, and the driving end of the flipping cylinder 41 is connected to the linkage 42 to drive the linkage 42 to rotate the crossbeam 2 relative to the fixed base 1. The flipping cylinder 41 drives the linkage 42 to rotate relative to the fixed base 1, and the rotation of the linkage 42 simultaneously drives the crossbeam 2 to rotate. The crossbeam 2 rotates with the suction cup, thereby achieving the flipping of the battery casing 6.

[0059] Optionally, refer to Figure 5 and Figure 6 The linkage part 42 is provided with a first limiting part 421, and the fixed base 1 is provided with a second limiting part 11. When the linkage part 42 rotates to a preset angle, the first limiting part 421 and the second limiting part 11 abut against each other to limit the linkage part 42 from continuing to rotate. The tilting cylinder 41 drives the linkage part 42 to rotate relative to the fixed base 1. The rotation of the linkage part 42 simultaneously drives the crossbeam 2 to rotate. When the linkage part 42 rotates to a predetermined angle, the first limiting part 421 and the second limiting part 11 abut against each other to limit the linkage part 42 from continuing to rotate, thereby limiting the rotation angle of the crossbeam 2.

[0060] For example, the crossbeam 2 is provided with a handle, as shown in the reference. Figure 5 After pulling the handle to attach the suction cup 3 to the battery case 6, the electric hoist moves the battery case 6 to the location of the material rack. The control unit 5 controls the drive end of the flipping cylinder 41 to push one end of the linkage part 42 downward, causing the linkage part 42 to rotate relative to the fixed base 1. The linkage part 42 drives the crossbeam 2 to rotate, flipping the direction of the battery case 6, so that the battery case 6 is flipped to a predetermined angle and placed on the material rack.
