The swing arm 410 is provided with a hinge base 411 hinged to the holding clip 620, and the holding clip 620 is rotatable around a position where it is hinged to the hinge base 411. Before clamping the soft package battery core 20, the holding clamp 620 is rotated to separate the fastening block 630 from the base 610, so that the positioning groove 611 on the base 610 is exposed, and the soft package battery core 20 to be packaged is placed in the positioning groove 611; in the reverse rotation of the retaining clip 620, the fastening block 630 is attached to the base 610 again, so that the soft package battery cell 20 is pressed in the positioning groove 611, and the soft package battery cell 20 is conveniently taken and placed.
It will be understood that referring to fig. 5 and 6, the area of the positioning groove 611 on the single base 610 is limited, that is, the number of positioning grooves 611 on each base 610 is limited by the size of the base 610, when the standard of the packaged battery 20 required to be produced by the same automatic packaging machine 10 is greater than the number of positioning grooves 611 on the single base 610, the base 610 needs to be replaced to meet the production requirement, the carrier clamp 13 further includes a magnetic block 710 and an insert 720, the magnetic block 710 is disposed on the swing arm 410, a limiting hole 612 is formed at the center of the base 610, the insert 720 is embedded in the limiting hole 612, the thickness of the insert 720 is smaller than the depth of the limiting hole 612, the end of the insert 720 is spaced from the opening position of the limiting hole 612, the magnetic block 710 extends into the space and is attached to the insert 720, and the insert 720 is made of an iron alloy or other metal material with magnetic absorption capability, and the magnetic block 710 is used for absorbing the insert 720. The base 610 is fixed on the swing arm 410 by the magnetic force provided by the magnetic block 710, and when the base 610 is replaced, only the force is needed to overcome the magnetic force of the magnetic block 710, and other tools are not needed. Preferably, the magnet 710 is a samarium cobalt magnet having heat resistance.
When the base 610 is pulled out, the applied pulling force should be greater than the adsorption force provided by the magnetic block 710, and when the base 610 is separated from the swing arm 410, the reaction force acts on the swing arm 410, which can cause the swing arm 410 to shake obviously, and the manner of pulling out the base 610 directly is unfavorable for the force application of the operator. The material loading clamp 13 is convenient to replace, the swing arm 410 is provided with the boss 412, the boss 412 is located on the end face of the swing arm 410, which is in contact with the base 610, the boss 412 is arc-shaped, the boss 412 takes the magnetic block 710 as the center of a circle, the thickness of the boss 412 increases gradually from the starting end 412a to the ending end 412b, the boss 412 is at least provided with 2, each boss 412 takes the magnetic block 710 as the center and is distributed in a circumferential array, the base 610 is provided with a profiling groove matched with the boss 412, and the boss 412 is attached to the inner wall of the profiling groove, as shown in fig. 8.
Referring to fig. 8 and 9, when the base 610 needs to be replaced, a maintainer holds the outer wall of the base 610 with one hand, rotates the base 610 to rotate the profiling groove relative to the boss 412, and the direction of rotation is from the start end 412a to the end 412b of the boss 412, as shown by the arrow 1 in fig. 7, since the thickness of the boss 412 increases from the start end 412a to the end 412b, when the base 610 rotates in this direction, the base 610 is lifted by the boss 412, so that the magnet 710 is separated from the insert 720, as shown in fig. 9, and finally the base 610 is directly removed from the boss 412. The process of separating the magnetic block 710 from the insert 720 is prolonged through the boss 412, the impulsive force generated during the separation of the magnetic block 710 and the insert 720 is reduced, the problem of shaking during the replacement of the base 610 can be effectively avoided, the problem that the swing arm 410 and parts connected with the swing arm 410 are deformed under stress or the fixed position is deviated due to the repeated replacement of the base 610 is further avoided, and the service life of the equipment is prolonged.
