Since the battery cell is the key part of the entire battery, its internal environment should be ensured during the installation process to avoid the presence of debris inside the steel shell, which will affect the service life of the battery. In the current battery production process, since the incoming steel shell is shipped in a paper box, it is inevitable that some debris from the outer packaging will remain in the steel shell, and the battery cell needs to be shipped in a plastic box. In the process of converting to a plastic box, the packaging paper scraps and floating dust and other debris remaining inside the steel shell, the vacuum device of the equipment cannot effectively eliminate the foreign matter inside the steel shell; at the same time, some floating dust and foreign matter will remain inside the cylindrical steel shell during the box turning process. In the existing equipment, the steel shell mouth is adsorbed by an open vacuum surface during the box turning, and the effect is not ideal. Paper scraps and floating dust and foreign matter left over during the transportation process are often left inside the steel shell, which will affect the subsequent battery cell entry and cause the battery cell to be contaminated.

It can simultaneously act on multiple steel shells 101 for positive pressure blowing and negative pressure suction.

[0042] A sleeve 225 corresponding to the position of the air blowing pipe 2111 is provided in the negative pressure fixing plate 22, and the top end of the air blowing pipe 2111 passes through the sleeve 225 and exceeds the top of the negative pressure fixing plate 22, so that the air blowing pipe 2111 can extend into the steel shell 101 for blowing.

[0043] In order to ensure that the air nozzles at the top of the multiple air blowing tubes 2111 on the positive pressure movable plate 21 have sufficient pressure, the bottom end of the air blowing tube 2111 is inserted into 1 / 3 to 1 / 2 of the tube diameter of the positive pressure air blowing flow channel 212.

[0044] A vacuum adsorption working plate 224 is provided on the top of the negative pressure fixing plate 22 , and the air blowing pipe 2111 and the vacuum adsorption pipeline 223 penetrate the vacuum adsorption working plate 224 upward.

[0045] The diameter of the air blowing pipe 2111 is 6 mm, and the diameter of the positive pressure air blowing channel 212 is 10 mm.

[0046] A cleaning device for battery cell shelling equipment includes a top cover 1, a paper box 3, a plastic box 4, and the above-mentioned mechanism body 2, wherein the top cover 1 is located above the mechanism body 2, and a plurality of steel shells 101 with openings facing downward are arranged in the top cover 1, and the mechanism body 2, the paper box 3, and the plastic box 4 are arranged in sequence according to the processing flow of the steel shell 101.

Since the negative pressure fixing plate 22 is in a normally open adsorption state, part of the debris lifted downward is adsorbed by the vacuum adsorption pipe 223, and the other part is attached to the vacuum adsorption working plate 224, so as to clean the dust and debris and paper scraps inside the steel shell 101, thereby preventing the battery cell from being contaminated after entering the shell. Example 1

[0048] The other structures are the same as those in Example 1, except that an air blowing mechanism is used to replace the air blowing pipe 2111 in Example 1.

[0049] like Figure 6-Figure 9As shown, the blowing mechanism includes an air blowing pipe 2111, a movable air outlet sleeve 2112, a support frame 2113, and a sliding rod 2114. The air blowing pipe 2111 is provided with the movable air outlet sleeve 2112 and the support frame 2113, wherein the support frame 2113 is slidably connected to the air blowing pipe 2111, the movable air outlet sleeve 2112 is fixedly connected to the air blowing pipe 2111, and the support frame 2113 is located below the movable air outlet sleeve 2112. One end of the slide rod 2114 is connected to the support frame 2113, and the other end of the slide rod 2114 passes through the top of the movable air outlet sleeve 2112. A penetrating circular hole is provided in the support frame 2113. The slide rod 2114 is a hollow tube and is connected to the circular hole in the support frame 2113, thereby forming an air flow channel. The movable air outlet sleeve 2112 is an internal hollow structure, and the top end is an arc-shaped end face, and a strip-shaped air outlet hole 2119 communicating with the interior is provided on the arc surface.

[0050] A connecting tube 2115 is sleeved on the middle part of the sliding rod 2114, and the bottom end of the connecting tube 2115 is fixedly connected to the top of the movable air outlet sleeve 2112. A sealing plate 2116 is provided on the top of the connecting tube 2115. A stopper 2118 is sleeved on the top of the sliding rod 2114, and is located between the sealing plate 2116 and the stopper 2118. A spring 2117 is also sleeved on the sliding rod 2114, and the two ends of the spring 2117 are respectively in contact with the stopper 2118 and the sealing plate 2116, and the sealing plate 2116 can move up and down along the sliding rod 2114.

[0051] A cleaning device for battery cell shelling equipment includes a top cover 1, a paper box 3, a plastic box 4, and the above-mentioned mechanism body 2, wherein the top cover 1 is located above the mechanism body 2, and a plurality of steel shells 101 with openings facing downward are arranged in the top cover 1, and the mechanism body 2, the paper box 3, and the plastic box 4 are arranged in sequence according to the processing flow of the steel shell 101. The outer diameter of the air blowing pipe 2111 is smaller than the inner diameter of the steel shell 101, and the stopper 2118 can extend to the middle of the steel shell 101.

[0052] The working principle of a cleaning device for battery cell shelling equipment: Figure 1-Figure 11As shown, the steel shell 101 needs to convert the paper box 3 packaging into the plastic box 4 packaging during the transportation process. First, the mouth of the steel shell 101 is facing downward and the bottom is facing upward, and the bottom end of the steel shell 101 is stuck in the top cover 1. When the conveying mechanism is sent to the fixed position and paused, the positive pressure movable plate 21 rises a certain distance along the positioning guide rod 221, so that the blowing mechanism 211 extends into the steel shell 101 about 20 mm when working. Through the cylinder and the air valve connected to the outside, after the air valve is opened for 1 second, the cylinder conveys gas to the positive pressure blowing flow channel 212, and the positive pressure blowing flow channel 212 is connected to the blowing pipe 2111 in the blowing mechanism, so that the gas in the blowing pipe 2111 pushes the support frame 2113 upward, so that the gas in the movable air outlet sleeve 2112 is compressed. , and then blown out from the strip air outlet 2119, thereby impacting the inner wall of the steel shell; a small amount of gas will enter the bottom end of the steel shell 101 along the circular hole on the support frame 2113 and the inner wall of the sliding rod 2114, and use the explosiveness and the single-sided opening structure of the steel shell 101 to blow out the floating dust and debris inside the steel shell 101, and then close the air valve, and the support frame 2113 moves downward due to the loss of upward thrust; the negative pressure fixed plate 22 is connected to the external suction equipment. Since the negative pressure fixed plate 22 is in a normally open adsorption state, part of the debris lifted downward is adsorbed by the vacuum adsorption pipe 223, and the other part is attached to the vacuum adsorption working plate 224, so as to clean the floating dust, debris and paper scraps inside the steel shell 101, thereby preventing the battery cell from being contaminated after entering the shell.

[0053] When the gas is blown out from the strip-shaped air outlet 2119 , it will also push the sealing plate 2116 upward to prevent paper scraps and floating dust blown down from the top of the sliding rod 2114 from entering the interior of the blowing mechanism 211 through the strip-shaped air outlet 2119 and causing pollution to the internal environment of the blowing mechanism 211 .

[0054] In the second embodiment, the blowing mechanism is used to replace the blowing pipe 2111 in the first embodiment, so that the effect of cleaning the floating dust, debris and paper scraps inside the steel shell 101 is more obvious and less prone to clogging.
