Description

Technical Field

[0001] The utility model relates to the technical field of button batteries, in particular to a sealing mould for button batteries. Background Art

[0002] Button batteries are a commonly used high-energy battery. They have become the main power source for various portable electronic products due to their advantages such as high operating voltage, high energy density, long cycle life, and no memory effect. In the production process of button batteries, the outer shell cover and inner shell cover of the button battery need to be initially combined and sealed using a sealing mold.

[0003] Patent No. CN214099833U proposes a reliable sealing mold for button batteries, in which a lower heating element is provided on the outside of the sealing groove. When the inner cover and the outer cover of the button battery are placed in the sealing groove, the heat of the lower heating element is transferred to the outer cover of the button battery. After the outer cover of the button battery is heated, the outer cover is more easily deformed and closed during sealing, so that the opening of the outer cover of the button battery fits tightly on the inner cover, thereby ensuring the reliability of the sealing of the button battery.

[0004] However, since the sizes of the lower mold core and the upper mold core match the size of the button battery, when the button battery is sealed, the gap between the button battery and the lower mold core is small, which is inconvenient for taking and unloading the button battery, reducing the unloading efficiency of the button battery.

[0025] like Figure 1 to Figure 3 As shown, an embodiment of the utility model proposes a button battery sealing mold, including: a lower mold 1 and an upper mold 2, the inner walls of the lower mold 1 and the upper mold 2 are fixed with a heating element 3, a pad 4 is slidably provided in the lower mold 1, the pad 4 is connected to the lower mold 1 through a sliding assembly 5, a support plate 6 is fixed to the bottom end of the inner wall of the lower mold 1, a groove 7 is opened at the top of the support plate 6, and the groove 7 is fixedly connected to the pad 4 through a first spring 8.

[0026] In this embodiment, the inner cover and the outer cover of the button battery are covered on the button battery, and then placed into the lower mold 1 together. When the upper mold 2 is closed downward, the button battery can be sealed with the cooperation of the heating element 3. When the sealing is completed, the upper mold 2 is removed, and the pad 4 is driven upward by the elastic action of the first spring 8. The pad 4 drives the button battery upward to push the button battery out, which facilitates the rapid demolding of the button battery and improves the feeding efficiency of the button battery.

[0027] In a further embodiment, Figure 2 As shown, the sliding assembly 5 includes sliders 51 fixedly arranged on both sides of the pad 4, and both sides of the inner wall of the lower mold 1 are provided with sliding grooves 52 for the sliders 51 to slide. A protective pad 9 that contacts the pad 4 is fixed on the top of the support plate 6.

[0028] First, place the button battery on the pad 4 in the lower mold 1, and then when the upper mold 2 moves downward to close the mold, the button battery and the pad 4 are driven downward by the extrusion of the upper mold 2. At the same time, with the cooperation of the slider 51 and the slide groove 52, the movement of the pad 4 is kept stable. When the pad 4 moves downward, it squeezes the first spring 8. When the pad 4 moves to contact the protective pad 9 on the support plate 6, it stops moving to seal the button battery. When the sealing is completed, the upper mold 2 is removed. At this time, the pad 4 is driven upward by the elastic action of the first spring 8 to eject the button battery and demold it.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, a bottom plate 10 is fixed to one side of the lower mold 1, a receiving plate 11 is fixed to the top of the bottom plate 10, a receiving groove 12 for placing button batteries is opened at the top of the receiving plate 11, a blowing component 13 is arranged in the receiving groove 12, and a control component 14 is arranged at the bottom end of the inner wall of the receiving groove 12.

[0030] After the button battery is taken out from the lower mold 1, the button battery is placed in the receiving groove 12. The control component 14 is squeezed under the action of the gravity of the button battery. The control component 14 can control the blowing component 13 to blow air, so as to cool the button battery by blowing air, thereby facilitating the rapid cooling of the button battery and improving the cooling efficiency of the button battery.

[0031] In a further embodiment, Figure 3 As shown, the blowing component 13 includes an annular groove 131 provided on the inner wall of the receiving groove 12, an annular tube 132 is fixed in the annular groove 131, the inner wall of the annular tube 132 is connected to a plurality of nozzles 133, a fan 134 connected to the annular tube 132 is fixed on one side of the receiving plate 11, and the control component 14 includes a bottom groove 141 provided on the bottom end of the inner wall of the receiving groove 12, a pressure plate 142 which contacts the button battery is inserted and connected in the bottom groove 141, the pressure plate 142 is fixedly connected to the bottom groove 141 through a second spring 143, a self-resetting switch 144 which contacts the pressure plate 142 is fixed at the bottom end of the inner wall of the bottom groove 141, and the self-resetting switch 144 is electrically connected to the fan 134.

[0032] When the button battery is placed in the receiving slot 12, the pressure plate 142 moves downward under the action of the gravity of the button battery, so that the pressure plate 142 squeezes the self-resetting switch 144, and the self-resetting switch 144 can turn on the fan 134. The fan 134 blows air to the annular tube 132 and then blows it out through the nozzle 133, so as to cool the button battery by blowing air, which is convenient for the rapid cooling of the button battery. When the button battery is cooled, the button battery is taken out of the receiving slot 12. At this time, the elastic action of the second spring 143 drives the pressure plate 142 to reset, so that the pressure plate 142 stops squeezing the self-resetting switch 144, thereby turning off the fan 134 and stopping blowing air.

[0033] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
