Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to an electric button battery packaging machine. Background Art

[0002] During the manufacturing process of button cells, the cells need to be sealed, but manual sealing has a low production efficiency.

[0003] CN201820148830.2 discloses a button battery packaging machine. Under the control of its control module, the driving device drives the clamping assembly to automatically seal the battery, thereby improving production efficiency. However, it is found that the sensor is set inside the lower mold. When in use, force is directly applied to the lower mold to detect the pressing force at the sealing point, which can easily lead to excessive pressing force between the upper mold and the lower mold, causing deformation or damage to the button battery shell. In addition, the accuracy is not high and when the sensor is damaged, the lower mold base needs to be disassembled for replacement. Utility Model Content

[0010] By adopting the above technical scheme, guide columns and guide rods inserted in the guide columns are fixedly arranged on both sides of the sealing mechanism, and the guide rods are raised and lowered in the guide holes in the guide columns for guidance, thereby avoiding uneven sealing due to the inclination of the upper and lower molds, and effectively improving the sealing accuracy.

[0011] Furthermore, the sealing mechanism includes a lower mold assembly arranged on the top of the middle box and an upper mold fixedly arranged on the top of the guide rod for cooperating with the lower mold assembly to seal the button battery. The lower mold assembly includes a lower mold base and a top core arranged in the middle of the lower mold base. The bottom of the top core passes through the top of the middle box and abuts against the pressure sensor below.

[0015] Furthermore, the operating box is provided with a control panel for controlling the sealing pressure, and the high-torque motor and the pressure sensor are electrically connected to the control panel.

[0016] By adopting the above technical solution, the control panel can display the packaging pressing force in real time, which is convenient for workers to adjust the packaging machine in time to change the sealing pressure, and seal button batteries of different specifications through the control panel.

[0017] Furthermore, a protection component is also provided in the operation box, and the protection component includes a relay and a switch power supply electrically connected to the control panel.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0030] like Figures 1 to 3 As shown, a button battery packaging machine is applied to the packaging and unpacking process of button batteries; wherein this embodiment comprises an operating box 1 and a sealing mechanism 2 arranged on the operating box 1 for sealing the button batteries, a middle box 3 is also provided between the top of the operating box 1 and the sealing mechanism 2, and the sealing mechanism 2 is movably connected to the middle box 3, and a driving component 4, a push plate 5 and a pressure sensor 6 arranged on the top of the push plate 5 are arranged in the middle box 3 from bottom to top, and the pressure sensor 6 comprises a pressure-sensitive contact portion 61 abutting against the top wall of the middle box 3.

[0031] like Figure 2 As shown, in this embodiment, a middle box 3 is arranged under the sealing mechanism 2 and a detachable and replaceable pressure sensor 6 is arranged in the middle box 3. The pressure sensor 6 is supported by a driving component 4 for driving the sealing mechanism 2, and abuts against the sealing mechanism 2. It is located above the driving component 4 and connected to the sealing mechanism 2. The sealing pressure can be monitored in real time and high-precision monitoring can be maintained to prevent damage to the button battery. When the driving component 4 starts to push the sealing mechanism 2 to perform the sealing operation, the pressure sensor 6 will first withstand the pressure and feed back the pressure value to the control system. The control system will make a judgment based on the preset pressure range. If the pressure exceeds the set safety range, the control system will immediately take corresponding measures, such as stopping the sealing operation, to protect the button battery from damage.

[0032] like Figure 2 As shown, a mounting pad 12 is further provided between the pressure sensor 6 and the push plate 5 of this embodiment, and the pressure sensor 6 is fixedly mounted on the mounting pad 12. The mounting pad 12 can provide a stable support for the pressure sensor 6 to position it, ensuring that the position of the pressure sensor 6 is fixed during the packaging process and will not be displaced due to force; and when the sensor needs to be repaired, the pressure sensor 6 can be removed from the mounting pad 12 for repair.

[0033] Further, such as Figure 1As shown, the driving assembly 4 of this embodiment includes a high torque motor 41 and a push rod 42 connected to the output shaft of the high torque motor 41, and the other end of the push rod 42 is fixedly connected to the bottom of the push plate 5; the high torque motor 41 is a motor set in the operating box 1 and can provide a large sealing pressure of up to 1200kg. In order to ensure the connection stability, a coupling is fixedly provided on the motor output shaft, and a square cutout is provided on the coupling to fit the bottom rotating block of the push rod 42. When the motor is driven, the output shaft rotates through the coupling to make the push rod 42 spiral upward, thereby driving the sealing mechanism 2 to seal the battery. The large sealing pressure can ensure good sealing between the positive and negative electrodes of large-sized button batteries and the sealing of the battery shell.

[0034] like Figure 1 As shown, the sealing mechanism 2 of this embodiment includes a lower mold assembly arranged at the top of the middle box 3 and an upper mold 23 fixedly arranged at the top of the guide rod 7 for cooperating with the lower mold assembly to seal the button battery, and the lower mold assembly includes a lower mold base 21 and a top core 22 arranged in the middle of the lower mold base 21, and the bottom of this top core 22 is penetrated through the top of the middle box 3 and abuts against the pressure sensor 6 below. When in use, the battery is placed in the lower mold base 21 and raised by the lower driving assembly 4 for sealing, and the top core 22 can accurately bear the sealing pressure of the driving assembly 4 by abutting against the pressure sensor 6, thereby improving the sealing accuracy and the large torque motor 41 below can provide high sealing pressure to seal large-sized button batteries.

[0035] Considering the sealing accuracy, Figure 3 As shown, guide components are also provided on both sides of the push rod 42 of this embodiment, and the guide components include a guide column 8 fixed on the top of the middle box 3 and a guide rod 7 fixed on the top of the operating box 1, and a guide hole 81 adapted to the guide column 8 is provided in the guide column 8, and the guide rod 7 is inserted in the guide hole 81. By fixing the guide column 8 and the guide rod 7 inserted in the guide column 8 on both sides of the sealing mechanism 2, the guide rod 7 can be raised and lowered in the guide hole 81 in the guide column 8, playing a guiding role. When performing the sealing operation, the guide rod 7 can ensure the balance of the upper and lower molds, and avoid the problem of uneven sealing due to the tilting of the upper and lower molds. The setting of this guide component effectively improves the sealing accuracy. By ensuring the correct alignment between the upper and lower molds, the force distribution during the sealing process is more uniform, and the sealing result is more accurate and consistent. Avoid uneven sealing due to the tilting of the upper and lower molds, and effectively improve the sealing accuracy.

[0036] like Figure 1 and Figure 3As shown, the operating box 1 of this embodiment is provided with a control panel 9 for controlling the sealing pressure, and the high torque motor 41 and the pressure sensor 6 are electrically connected to the control panel 9. The control panel 9 is used to seal according to button batteries of different specifications; and a protection component is also provided in the operating box, which includes a relay 10 and a switch power supply 11 electrically connected to the control panel 9. When the sealing pressure is too large, the relay 10 and the switch power supply 11 can be powered off in time to protect the equipment. The control panel 9 can also perform precise control according to button batteries of different specifications, thereby ensuring the consistency and accuracy of the sealing quality.

[0037] The working principle of this embodiment is as follows: in this embodiment, by arranging a pressure sensor 6 below the sealing mechanism 2, a driving assembly 4 for driving the sealing mechanism 2 is mounted below the pressure sensor 6 and abuts against the sealing mechanism 2, the sealing pressure can be monitored in real time with high precision to prevent damage to the button battery. Then, by arranging the middle box 3, the pressure sensor 6 can be detachably replaced and installed in the middle box 3, which is beautiful and generous, and the pressure sensor 6 can be easily replaced when it is damaged.
