Description

Technical Field

[0001] The utility model relates to the technical field of grippers, in particular to a sponge gripper suitable for gripping a whole layer of new energy battery cells. Background Art

[0002] During the production of new energy battery modules, after the cells are assembled into modules, they need to be placed in boxes. Because the batteries are very heavy, mechanical handling is the only option. Traditional clamping fixtures use two arms to hold the modules, causing the cells in the middle to easily collapse and even fall, causing accidents. Furthermore, the dimensions of the box are roughly the same as the module dimensions, and the clamps must be removed after the cells are one-third of the way into the box. Because the cells are squeezed together, they rebound and open outward after the pressure is removed, resulting in an awkward drop. Therefore, improvements are needed, and a sponge gripper suitable for gripping entire layers of new energy cells has been proposed. Utility Model Content

[0024] In order to make the technical means for realizing the present invention, the creative features, the objectives and the effects thereof easier to understand, the present invention is further described below with reference to specific illustrations.

[0025] like Figures 1 to 4 As shown,

[0026] The present embodiment provides a sponge suction device suitable for grabbing a whole layer of new energy battery cells, including a suction cup 1 and a flange plate 2 installed on the upper end of the suction cup 1, so as to connect a robotic arm through the flange plate 2. The suction cup 1 includes a substrate 11 and an insulating plate 12 arranged in conjunction with the substrate 11, and a sponge plate 13 installed at the lower end of the insulating plate 12. The substrate 11 and the insulating plate 12 are fitted and sealed to form a plurality of groups of vacuum suction chambers 15 separated from each other. Each group of vacuum suction chambers 15 is externally connected to an exhaust component and an air inlet component to perform vacuuming and breaking operations. The sponge plate 13 is provided with negative pressure adsorption holes 14 corresponding to the battery cell modules. The negative pressure adsorption holes 14 are connected to the vacuum suction chamber 15 through the vents 19 on the insulating plate 12 to absorb the battery cells.

[0027] In this embodiment, a sealing gasket is provided between the substrate 11 and the insulating plate 12, and the substrate 11 and the insulating plate 12 are fixed and locked by bolts. A partition 16 is provided in the substrate 11 to separate the vacuum suction chamber 15, so that the vacuum suction chamber 15 has a U-shaped structure, and the negative pressure adsorption holes 14 are respectively opened on both sides of the partition 16.

[0028] In this embodiment, the vacuum element includes a vacuum tube 3 and a vacuum base 31 for mounting the vacuum tube 3 on the base plate 11. The bottom of the vacuum tube 3 is fixedly connected to the vacuum base 31, which is fixedly connected to the base plate 11 via screws. The base plate 11 is provided with a vacuum hole 32 that communicates with the vacuum tube 3. The outer end of the vacuum tube 3 is provided with a threaded joint for connecting to an outer pipe fitting and then to a vacuum pump. The vacuum element removes the air pressure from the vacuum chamber 15, creating a negative pressure in the vacuum chamber 15.

[0029] In this embodiment, the air inlet component is an air pipe connector 4 installed on the substrate 11. One side of the air pipe connector 4 is installed in the vacuum breaking hole 41 corresponding to the substrate 11 through a threaded joint, and the other end is connected to the air inlet pipe to break the negative pressure state of the vacuum suction chamber 15 and allow the product to be separated from the suction cup 1.

[0030] In this embodiment, a negative pressure gauge 5 for detecting the internal air pressure of the vacuum suction chamber 15 is further provided on one side of the substrate 11. One side of the negative pressure gauge 5 is inserted into a substantially corresponding detection hole through a pipe joint 51. The negative pressure gauge is electrically connected and controlled to monitor the internal air pressure of the vacuum suction chamber 15 in real time.

[0031] The upper end of the battery cell is equipped with a pole protruding from the surface of the battery cell, and the surface of the battery cell is also equipped with an explosion-proof valve. The pole and the explosion-proof valve cannot be squeezed or adsorbed, so damage to the pole and the explosion-proof valve must be avoided during the suction and transportation process.

[0032] In order to solve the above problem, in one embodiment, the sponge board 13 is provided with a pole avoidance hole 17 and an explosion-proof valve avoidance hole 18 corresponding to the pole and the explosion-proof valve at the outer end of the battery cell, respectively, to accommodate the pole and the explosion-proof valve, respectively.

[0033] In this embodiment, a sponge suction device suitable for grabbing a whole layer of new energy battery cells can also be used in conjunction with a traditional clamp. A vacuum sponge suction cup 1 is added in the middle of the traditional clamp to prevent the battery cells in the middle of the battery module from collapsing and to stably guide the battery cells into the battery box.

[0034] The working principle of this utility model is:

[0035] The exhaust pipe 3 is connected to the vacuum pump to suck the vacuum cavity. The vacuum cavity is connected to the negative pressure adsorption hole 14 through the vent hole, and the air in the negative pressure hole of the sponge is extracted in turn, thereby establishing a vacuum to absorb the battery cell.

[0036] Suction cup 1 is equipped with multiple negative pressure gauges to monitor the negative pressure within each vacuum chamber in real time. Suction cup 1 is designed for a negative pressure of at least -90 kPa, with a suction force designed to be four times the weight of the battery cell to ensure safe movement. Base plate 11 also features an air inlet. Once the battery cell is in place, a solenoid valve controls compressed air, rapidly breaking the vacuum within the chamber and allowing the cell to be quickly released. A sealing gasket is placed between base plate 11 and insulating plate 12 to prevent leakage of negative pressure within the chamber.

[0037] An insulating plate 12 is provided under the substrate 11 to prevent the battery core from contacting metal and improve safety; a sponge is provided under the insulating plate 12 for sealing to prevent vacuum leakage, and the sponge is provided with negative pressure adsorption holes 14 to provide suction.

[0038] This device improves on traditional gripping with a suction cup. When placing batteries into the box, the suction cup grips the top of the battery cells, effectively eliminating the problem of opening the cells without occupying surrounding space. The gripping speed is fast: after the sponge is attached, vacuum is established within 0.5 seconds for gripping. The suction cup acts on all cells, eliminating the problem of intermediate cells falling, and the gripping process does not damage the cells.
