Description

Technical Field

[0001] The present application relates to the field of battery voltage reduction, and in particular to an automatic voltage reduction device for lithium-manganese button batteries. Background Art

[0002] The lithium-manganese dioxide button cell, also known as the lithium-manganese dioxide button cell, has a nominal voltage of 3V and is a common button cell. It uses metallic lithium as the negative electrode and manganese dioxide as the positive electrode, offering advantages such as high energy density, long cycle life, and low self-discharge.

[0003] The main function of the lithium-manganese button battery voltage reduction device is to reduce the high voltage of the battery to a low voltage suitable for equipment use, while ensuring stable current output. This voltage reduction device is particularly important in lithium-manganese button batteries because lithium-manganese button batteries have high energy density and voltage output. Direct use may cause damage to the equipment. The voltage reduction device can safely and effectively regulate the battery voltage to the range required by the equipment, protecting the equipment from high voltage shocks.

[0004] Conventional lithium-manganese button battery voltage reduction devices typically include a base, support rods, a turntable, a groove, a placement slot, a first fixing plate, and a first probe. The turntable is movably connected to the base via the support rods and can rotate on the base. The turntable's surface is provided with a groove for the battery. To reduce the voltage, the battery is placed in the groove, and then the first probe is used to reduce the voltage.

[0005] However, in the above technology, the batteries need to be placed into the grooves one by one to reduce the voltage, and after the voltage reduction is completed, the batteries need to be taken out of the grooves one by one. This method will greatly reduce the voltage reduction efficiency of the batteries. Summary of the Invention

[0006] In order to improve the problems existing in the above-mentioned technology, the present application provides an automatic voltage reduction device for lithium-manganese button batteries.

[0020] By adopting the above technical solution, when reducing the pressure, the feed plate is pushed toward the support plate until the needle rod passes through between the two control plates, and as the diameter of the needle rod continues to increase, the control plate is retracted into the control groove, so that the control rod can push the moving part to operate, thereby driving the pressure reduction part to contact the positive and negative poles of the battery, thereby performing the pressure reduction operation.

[0021] Optionally, the moving part includes: a lower pressure plate, a moving rod and a return spring, the lower pressure plate is rotatably mounted on the support plate, the moving rod passes through the support plate, the return spring is sleeved on the moving rod and one end is fixed to the support plate and the other end is fixed to the moving rod, and the pressure reducing part is arranged between the two moving rods.

When unloading, the electric cylinder 33 is started to pull the feeding plate 31 to push the sealing plate 23 open, so that the battery can fall onto the receiving plate 41; then, since the end of the battery close to the sealing plate 23 is heavy, the receiving plate 41 drives the battery to flip downward, and the end of the battery close to the sealing plate 23 can flip to a vertical state along the falling groove 511 for the voltage reduction operation; in this way, the battery can be placed horizontally in the unloading channel 25 instead of being placed vertically in the unloading channel 25, thereby increasing the number of batteries placed to reduce the frequency of continuously putting in batteries.

[0041] See also Figure 4 The two limiting plates 52 are fixed on the bottom wall of the feeding plate 31, and the distance between the two limiting plates 52 is equal to the outer diameter of the battery. The two limiting plates 52 can limit the battery to prevent the battery from tilting.

[0042] See also Figure 5 The reset portion 6 includes a coil spring 61, a reset rod 62, and a reset rope 63.

[0043] See also Figure 5 One end of the reset rope 63 is wound around the reset rod 62, and the other end is fixed to the bottom wall of the receiving plate 41 near the reset rod 62. After the battery falls into the storage tank 11, the coil spring 61 recovers its deformation to drive the reset rod 62 to reel the reset rope 63, so that the reset rope 63 can pull the receiving plate 41 to a horizontal state to continue to receive the battery.

[0044] See also Figure 6 A support plate 12 is fixedly provided on the side wall of the step-down platform 1, and a step-down assembly is provided between the support plate 12 and the feeding plate 31, and the step-down assembly is used to perform a step-down operation on the battery; the step-down assembly includes: a step-down part 9, two control parts 7 and two moving parts 8, and the two control parts 7 correspond to the two moving parts 8 one by one.

[0045] See also Figure 3 and Figure 6The control unit 7 includes a needle rod 71, a control plate 72, a control rod 73, and a control spring 74. The needle rod 71 is fixed to the side of the feed plate 31 facing away from the electric cylinder 33, and the diameter of the needle rod 71 gradually decreases from close to the feed plate 31 to away from the feed plate 31.

The control spring 74 is used to push the control plate 72 into the through hole 121. One end of the control rod 73 is fixed to the control plate 72, and the other end extends outward through the support plate 12. When reducing the pressure, the feed plate 31 is pushed toward the support plate 12 until the needle rod 71 passes between the two control plates 72. As the diameter of the needle rod 71 continues to increase, the control plate 72 is retracted into the control slot 122, so that the control rod 73 can drive the moving part 8 to operate, driving the pressure reducing part 9 to contact the positive and negative poles of the battery, thereby performing the pressure reduction operation.

The pressure reducing portion 9 is arranged between the two movable rods 82. When the control plate 72 is retracted into the control groove 122, the control rod 73 pushes the lower pressing plate 81 to flip, so that the lower pressing plate 81 presses the movable rod 82, so that the movable rod 82 can drive the pressure reducing portion 9 to contact the positive and negative poles of the battery.

[0048] See also Figure 6 The return spring 83 is sleeved on the moving rod 82, and one end of the return spring 83 is fixed to the support plate 12 and the other end is fixed to the moving rod 82. After the pressure reduction is completed, the feed plate 31 is pulled away from the support plate 12 so that the control plate 72 can be re-extended into the through hole 121; at the same time, the return spring 83 can reset the moving rod 82.

[0049] See also Figure 3 and Figure 6The voltage reduction unit 9 includes: a first probe 91 and a second probe 92. The first probe 91 is installed on one end of one of the moving rods 82 away from the lower pressing plate 81, and the second probe 92 is installed on the other end of the moving rod 82 away from the lower pressing plate 81. When the lower pressing plate 81 presses the moving rod 82 to move, the first probe 91 and the second probe 92 continue to approach each other until they contact the positive and negative poles of the battery, thereby performing a voltage reduction operation.

[0050] The working principle of the automatic voltage reduction device for lithium-manganese button batteries of the present application when in use is as follows: when unloading, the electric cylinder 33 is started to pull the feeding plate 31 to push open the sealing plate 23, so that the battery can fall onto the receiving plate 41; then, since the end of the battery close to the sealing plate 23 has a large weight, the receiving plate 41 drives the battery to flip downward, and the end of the battery close to the sealing plate 23 can be flipped to a vertical state along the falling groove 511 for the voltage reduction operation; in this way, the battery can be placed horizontally in the unloading channel 25 instead of vertically in the unloading channel 25, thereby increasing the number of batteries placed to reduce the frequency of continuously adding batteries.
