Description

Technical Field

[0001] This invention relates to the field of gripping equipment technology, specifically to a multi-configuration magnetic suction-gripper composite device. Background Technology

[0002] Grippers are used in the electric vehicle industry for handling cylindrical batteries. Traditional pneumatic grippers can cause battery damage when gripping cylindrical car batteries, and they require a large assembly space, which significantly reduces the number of batteries that can be gripped. While electric grippers do not damage cylindrical batteries, they are expensive and also require a large assembly space. Magnetic gripper devices completely avoid these risks, and are more efficient, more stable, and less expensive. The existing magnetic grippers still have shortcomings. Specifically, the existing magnetic grippers rely only on end-face adsorption. During high-speed handling, emergency stops, inversions, and 90° rotations, the battery cells are prone to being thrown off or shifting, resulting in low safety. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-configuration magnetic suction-gripper composite device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A multi-configuration magnetic suction-gripper composite device includes a cylinder, the outer wall of which is provided with a clamping mechanism for composite clamping of a cylindrical battery, and a rear cover is fixedly installed on the outer wall of the cylinder on the side away from the clamping mechanism. An upper air inlet and a lower air inlet are provided on both sides of the center of the front of the cylinder for gas inflow.

[0005] In a preferred embodiment of the present invention, the clamping mechanism includes a gripper housing fixedly connected to the outer wall of the cylinder. A wedge block is slidably connected inside the gripper housing. A connecting rod is fixedly connected to the center of the wedge block. A piston plate is fixedly connected to the outer wall of the connecting rod inside the cylinder. Base claws are slidably connected to the outer wall of the wedge block above, below, on the front, and on the back of the connecting rod. A gripping finger is fixedly connected to the outer wall of the base claw outside the gripper housing. A magnet is slidably connected to the inside of the gripper housing near the wedge block. A lower cover is fixedly connected to the outer wall of the gripper housing on the side away from the cylinder. A spacer is fixedly connected to the inside of the gripper housing near the magnet. A suction block is fixedly connected to the outer wall of the connecting rod inside the gripper housing.

[0006] As a preferred embodiment of the present invention, both the cylinder and the rear cover are made of aluminum alloy. The cylinder has a hollow cylindrical structure design, and the rear cover is a thin disc-shaped flange with a central annular stop.

[0007] As a preferred embodiment of the present invention, the gripper housing, wedge, connecting rod, base claw, gripping finger, and lower cover are all made of aluminum alloy. The gripper housing has a hollow cylindrical structure design. The connecting rod passes through the gripper housing and extends into the cylinder. The piston plate is connected to the cylinder, the connecting rod is connected to the gripper housing, and the base claw is connected to the gripper housing by sliding connection.

[0008] As a preferred embodiment of the present invention, the piston plate is composed of multiple concentric cylindrical steps and is generally disc-shaped. Multiple sets of sealing rubber rings are fixedly connected to the outer wall of the piston plate, and four sets of clamping fingers and base claws are provided.

[0009] Through the above technical solution, the sealing rubber ring can improve the sealing performance of the piston plate and prevent compressed air leakage.

[0010] As a preferred embodiment of the present invention, the clamping finger is a slender rod, and the upper and lower ends of the clamping finger are ear-shaped structures with holes. The suction block is designed as a flat disc, and the base claw extends through and out of the claw housing.

[0011] As a preferred embodiment of the present invention, the magnets are provided in two sets, the magnets are designed with a semi-cylindrical structure, and the magnets are connected to the connecting rods in a fixed manner.

[0012] In a preferred embodiment of the present invention, an anti-slip rubber pad is fixedly connected to the outer wall of the finger clamping device, the suction block is designed as a flat disc-shaped structure, and the spacer is designed as a short and thick cylindrical structure. Through the above technical solutions, the anti-slip rubber pad can increase the surface friction of the fingers and improve the gripping stability.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a multi-configuration magnetic suction-gripper composite device is designed. The clamping mechanism within this device grips a cylindrical battery. The cylinder and gripper housing are moved onto the cylindrical battery, with the lower cover pressing against the top of the battery. Compressed air is injected into the upper air inlet, flowing into the cylinder and pushing the piston plate forward. The piston plate, via a connecting rod, drives the wedge and magnet forward. The magnet approaches and attracts the battery cell. As the wedge moves forward, it simultaneously pushes the base claw inward. The inward-moving base claw then moves the gripping fingers closer to and clamps the cylindrical battery. The claw housing and cylinder drive the battery to move, and then compressed air is injected into the lower air inlet. The compressed air in the lower air inlet pushes the piston plate to move in the opposite direction. The piston plate drives the wedge and rack to move in the opposite direction to the starting position through the connecting rod. The magnet moves away from the cylindrical battery, and the cylindrical battery falls off. It is first attracted by magnetic contact, without squeezing, indenting, or damaging the housing. The claw only performs light clamping / auxiliary positioning to completely avoid deformation and denting. This solves the problem that existing magnetic claws only rely on end face adsorption, which makes the battery cells easy to fly off and shift when transporting at high speed, stopping suddenly, hanging upside down, or flipping 90°, resulting in low safety.

[0020] Furthermore, the gripper housing 201, wedge 202, connecting rod 203, base claw 205, gripping finger 206, and lower cover 208 are all made of aluminum alloy.

[0021] Furthermore, the piston plate 204 is composed of multiple concentric cylindrical steps and is in the shape of a disc.
