[0015] The cylindrical battery sealing processing method comprises the following steps:

[0016] Step 1: During the sealing process of the cylindrical battery to be sealed, the cylinder to be sealed is inserted into the battery holder on the front side of the battery rotating disk in turn, and then the battery rotating disk is driven counterclockwise by the motor 1. When the battery holder with the cylindrical battery to be sealed is rotated to the position of the sealing processing mechanism, the sealing die is driven downward by the cylinder, and the top cover of the cylindrical battery to be sealed is stamped into its shell by stamping, so as to achieve the sealing of the cylindrical battery to be sealed;

[0017] Step 2: During the downward movement of the sealing mold, the two linkage rods located below the sealing mold are first moved upward by the reaction force of the cylindrical battery to be sealed. At the same time as the linkage rods move upward, the movable slider connected to the linkage rods slides upward on the outside of the sealing mold, and the upper end of the linkage arm connected to the outside of the movable slider moves upward, and its lower end together with the sealing edge clamp ring moves toward the sealing position of the top cover and the shell of the cylindrical battery to be sealed, thereby evenly applying pressure to the joint between the top cover and the shell;

[0018] Step 3: When the cylindrical battery to be sealed above the battery rotating disk rotates and is sealed by the sealing processing mechanism and then rotates to the position of the sealing processing testing mechanism, the eccentric wheel is driven to rotate by the second motor. While the eccentric wheel rotates, the transmission rod sleeved on the outer side of the eccentric wheel and the reciprocating ejector rod reciprocate back and forth, and the reciprocating ejector rod continuously hits the upper sealing position of the cylindrical battery to be sealed in a circular movement manner;

[0019] Step 4: If the battery is not tightly sealed after sealing, the top cover of the cylindrical battery to be sealed will be lifted up. While the top cover is lifted up, friction is generated between the top cover and the movable ball under the ink marking tube, causing the movable ball to rotate. The movable ball smears a small amount of ink in the ink marking tube on the surface of the top cover of the cylindrical battery to be sealed, forming a color mark, which makes it easier for processing personnel to judge whether the top cover of the cylindrical battery to be sealed is lifted up. Processing personnel can intuitively identify batteries with sealing problems.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, by setting up a sealing processing and testing mechanism, during the sealing processing of the cylindrical battery to be sealed, the battery rotating disk is driven to rotate by the first motor. When the cylindrical battery to be sealed above the battery rotating disk is rotated to the position of the sealing processing and testing mechanism after being sealed by the sealing processing mechanism, the eccentric wheel is driven to rotate by the second motor. While the eccentric wheel rotates, the transmission rod sleeved on the outer side of the eccentric wheel and the reciprocating ejector rod perform a back and forth reciprocating motion. The reciprocating ejector rod continuously hits the upper sealing position of the cylindrical battery to be sealed in a circular moving manner. If the sealing is seriously loose, The top cover of the cylindrical battery to be sealed is lifted up and separated from the shell. If the battery is not tightly sealed after the sealing process, the top cover of the cylindrical battery to be sealed is lifted up. While the top cover is lifted up, the top cover and the movable ball under the ink marking cylinder produce friction, causing the movable ball to rotate. The movable ball smears a small amount of ink in the ink marking cylinder on the surface of the top cover of the cylindrical battery to be sealed, forming a color mark, which is convenient for processing personnel to judge whether the top cover of the cylindrical battery to be sealed is lifted up. Processing personnel can intuitively identify batteries with problems in sealing processing and manufacturing, which is convenient for timely rework or removal;

[0022] 2. In the present invention, through the sealing processing mechanism, during the sealing process of the cylindrical battery to be sealed, the cylinder to be sealed is inserted into the battery holder on the front side of the battery rotating disk in sequence, and then the battery rotating disk is driven counterclockwise by the motor 1. When the battery holder with the cylindrical battery to be sealed is rotated to the position of the sealing processing mechanism, the sealing mold is driven by the cylinder to move down, and the top cover of the cylindrical battery to be sealed is punched into its shell by stamping to achieve the sealing of the cylindrical battery to be sealed. In addition, during the downward movement of the sealing mold, the two linkage rods located below the sealing mold are first moved upward by the reaction force of the cylindrical battery to be sealed. At the same time as the linkage rod moves upward, the movable slider connected to the linkage rod slides upward on the outside of the sealing mold, and the upper end of the linkage arm connected to the outside of the movable slider moves upward, and its lower end together with the sealing edge snap ring are close to the sealing position of the top cover and the shell of the cylindrical battery to be sealed, thereby evenly applying pressure to the junction of the top cover and the shell, ensuring the uniformity and sealing of the sealing process of the cylindrical battery to be sealed.

[0038] During the sealing process of the cylindrical battery 12 to be sealed, the cylindrical battery to be sealed is inserted into the battery holder 6 on the front side of the battery rotating disk 2 in sequence, and then the battery rotating disk 2 is driven counterclockwise by the motor 3. When the battery holder 6 with the cylindrical battery 12 to be sealed is inserted rotates to the position of the sealing processing mechanism 5, the sealing mold 503 is driven downward by the cylinder 502, and the top cover of the cylindrical battery 12 to be sealed is stamped onto its shell by stamping, so as to achieve the sealing of the cylindrical battery 12 to be sealed. In addition, during the downward movement of the sealing mold 503, the sealing mold 503 is located at the sealing mold 503. The two linkage rods 506 below 503 are first moved upward by the reaction force of the cylindrical battery 12 to be sealed.

[0039] The cylindrical battery sealing processing method comprises the following steps:

[0040] Step 1: During the sealing process of the cylindrical battery 12 to be sealed, the cylindrical battery to be sealed is inserted into the battery holder 6 on the front side of the battery rotating disk 2 in sequence, and then the battery rotating disk 2 is driven counterclockwise by the motor 13. When the battery holder 6 with the cylindrical battery 12 to be sealed is rotated to the position of the sealing processing mechanism 5, the sealing die 503 is driven downward by the cylinder 502, and the top cover of the cylindrical battery 12 to be sealed is stamped into its shell by stamping, so as to achieve the sealing of the cylindrical battery 12 to be sealed;

[0041] Step 2: During the downward movement of the sealing mold 503, the two linkage rods 506 located below the sealing mold 503 are first moved upward by the reaction force of the cylindrical battery 12 to be sealed. At the same time as the linkage rods 506 move upward, the movable slider 504 connected to the linkage rods 506 slides upward on the outside of the sealing mold 503, and the upper end of the linkage arm 505 connected to the outside of the movable slider 504 moves upward, and the lower end thereof together with the sealing edge clamp 508 moves toward the sealing position of the top cover and the shell of the cylindrical battery 12 to be sealed, thereby evenly applying pressure to the joint between the top cover and the shell;

[0042] Step 3: When the cylindrical battery 12 to be sealed above the battery rotating disk 2 rotates and is sealed by the sealing processing mechanism 5 and then rotates to the position of the sealing processing testing mechanism 4, the eccentric wheel 407 is driven to rotate by the second motor 406. While the eccentric wheel 407 rotates, the transmission rod 408 sleeved on the outer side of the eccentric wheel 407 and the reciprocating ejector rod 409 make a back-and-forth reciprocating motion, and the reciprocating ejector rod 409 continuously hits the upper sealing position of the cylindrical battery 12 to be sealed in a circular motion;

[0043] Step 4: If the battery is not tightly sealed after the sealing process, the top cover of the cylindrical battery 12 to be sealed will be lifted up. While the top cover is lifted up, friction is generated between the top cover and the movable ball 415 under the ink marking tube 414, causing the movable ball 415 to rotate. The movable ball 415 smears a small amount of ink in the ink marking tube 414 on the surface of the top cover of the cylindrical battery 12 to be sealed, forming a color mark, which makes it convenient for the processing personnel to judge whether the top cover of the cylindrical battery 12 to be sealed is lifted up, and the processing personnel can intuitively identify the battery with sealing problems.

The cylindrical battery sealing device according to claim 1, characterized in that: A battery storage cavity (9) is provided inside the sealing processing table (1), and three storage plates (11) are provided inside the battery storage cavity (9) from top to bottom, and both ends of the storage plates (11) are slidably connected to the inner sides of two slide rails (10), and the slide rails (10) are fixedly connected to the sealing processing table (1).

9. The cylindrical battery sealing device according to claim 1, characterized in that: A good product placement table (7) is fixedly connected to the front side above the sealing processing table (1), and a defective product placement table (8) is fixedly connected to the right side above the sealing processing table (1).

10. The cylindrical battery sealing processing device according to any one of claims 1 to 9, characterized in that: The processing method of the cylindrical battery sealing processing device comprises the following steps: Step 1: During the sealing process of the cylindrical battery (12) to be sealed, the cylindrical battery to be sealed is sequentially inserted into the battery holder (6) on the front side of the battery rotating disk (2), and then the battery rotating disk (2) is driven counterclockwise by the motor 1 (3). When the battery holder (6) with the cylindrical battery (12) to be sealed is inserted rotates to the position of the sealing processing mechanism (5), the cylinder (502) drives the sealing mold (503) to move downward, and the top cover of the cylindrical battery (12) to be sealed is stamped onto its shell by stamping, thereby sealing the cylindrical battery (12) to be sealed; Step 2: During the downward movement of the sealing mold (503), the two linkage rods (506) located below the sealing mold (503) are first moved upward by the reaction force of the cylindrical battery (12) to be sealed. At the same time as the linkage rods (506) move upward, the movable slider (504) connected to the linkage rods (506) slides upward on the outer side of the sealing mold (503). The upper end of the linkage arm (505) connected to the outer side of the movable slider (504) moves upward, and the lower end thereof together with the sealing edge clamp (508) moves toward the sealing position of the top cover and the shell of the cylindrical battery (12) to be sealed, thereby evenly applying pressure to the joint between the top cover and the shell; Step 3: When the cylindrical battery (12) to be sealed above the battery rotating disk (2) rotates and is sealed by the sealing processing mechanism (5) and then rotates to the position of the sealing processing testing mechanism (4), the eccentric wheel (407) is driven to rotate by the second motor (406). While the eccentric wheel (407) is rotating, the transmission rod (408) sleeved on the outer side of the eccentric wheel (407) together with the reciprocating ejector rod (409) perform a back-and-forth reciprocating motion, and the reciprocating ejector rod (409) continuously strikes the upper sealing position of the cylindrical battery (12) to be sealed in a circular motion; Step 4: If the battery is not tightly sealed after the sealing process, the top cover of the cylindrical battery (12) to be sealed is lifted up. When the top cover is lifted up, friction is generated between the top cover and the movable ball (415) below the ink marking tube (414), causing the movable ball (415) to rotate. The movable ball (415) smears a small amount of ink in the ink marking tube (414) on the surface of the top cover of the cylindrical battery (12) to be sealed, forming a color mark, which makes it easier for processing personnel to determine whether the top cover of the cylindrical battery (12) to be sealed is lifted up. The processing personnel can intuitively identify the battery with sealing problems.
