Description

Technical Field

[0001] The present invention relates to grid forming technology, and in particular to a method for forming a grid of a lead-acid battery. Background Art

[0002] Lead-acid batteries have been accepted by the majority of consumers in the past decade, mainly in aspects such as electric bicycles, automotive starting, and energy storage of solar and wind energy. Therefore, manufacturers have racked their brains to improve production efficiency, reduce grid costs, and improve product quality. When gravity casting, the grid molds are all vertically placed, so the cast grids are all vertically placed. This requires that the just-cast grid must be converted from a vertical state to a horizontal state. Currently, the common practice is to let the grid freely fall onto an arc-shaped slide plate and slide from a vertical state to a horizontal state. The impact on the grid during the whole process is relatively large. Coupled with the fact that the material of the grid is lead and the just-cast grid is very soft, it is easy for the grid to deform during the whole process, affecting the subsequent processes and the quality of the finished battery.

[0003] When producing traditional grids, a grid roll-casting mold is used, which directly casts with a molten lead furnace. However, in actual production, it is not easy to control the discharge of lead water and difficult to control the flow rate of lead water. When using a lead pipe to transport lead water, after a certain amount of lead water is transported, it is not easy to timely control the stop of lead water, resulting in the loss of lead water, a large amount of lead water waste, and the slowdown of the processing progress, leading to a reduction in the overall production efficiency. Summary of the Invention

[0004] In order to solve the defects existing in the above-mentioned prior art, the present invention proposes a method for forming a grid of a lead-acid battery.

Step 4: Push the gear member on the rotating shaft to rotate through the first teeth on the pusher, so that the driving member on the rotating shaft rotates. Step Five: The driving member rotates 90°, pushing the sealing member upward to keep the space between the sealing member and the holding member separated. The lead water flows down between the sealing member and the holding member. Meanwhile, the driving member closes the blocking opening on the blocking member. Step Six: After the second forming roller continues to rotate, the pushing member moves downward, keeping the first tooth driving the gear member to rotate in the reverse direction, so that the rotating shaft also rotates in the reverse direction, keeping the driving member rotating 90° in the reverse direction.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] As Figures 1 to 14 shown, the grid forming method of this lead-acid battery of the present invention includes the following steps: Step 1: Pour the molten lead into the liquid storage tank 2 in the liquid storage mechanism 1, and heat the lead through the electric heating rod inside the liquid storage tank 2 to keep the temperature of the lead within the set temperature range. The electric heating rod can be arranged in the liquid storage area 27 to ensure that the temperature of the lead is in a constant state.

[0019] Step 2: Start the first forming roller 14 and the second forming roller 15. The rotation directions of the first forming roller 14 and the second forming roller 15 are opposite and rotate towards each other. A motor can be arranged on the first rotating shaft in the middle of the first forming roller 14, and then gears are arranged on the first rotating shaft 66 and the second rotating shaft 17. The gears are meshed with each other to keep the rotation between the gears in the reverse direction, so that both the first forming roller 14 and the second forming roller 15 rotate towards the middle. At the same time, the second forming roller 15 drives the driven disk 18 to rotate, so as to drive the pushing member 7 to rotate around the second rotating shaft 17, and keep the rotating shaft 11 capable of rotating clockwise and counterclockwise by 90°.

[0020] Step 3: Through the rotation of the second forming roller 15, drive the pushing member 7 hinged on the second forming roller 15 to rotate around the central axis of the second forming roller 15, so that the upper end of the pushing member 7 is in an active state. When the second forming roller 15 rotates, it can drive the hinge shaft 19 to rotate around the second rotating shaft 17. Before the hinge shaft 19 reaches the highest point, the pushing member 7 keeps moving upward. After the hinge shaft 19 passes the highest point, it is to keep the pushing member 7 moving downward, so that the first tooth 65 and the second tooth 13 are in contact and cooperate, and keep the rotating shaft 11 capable of rotating clockwise and counterclockwise. And the number of the first teeth 65 can only drive the gear member 12 to rotate by 90°. When the pushing member 7 continues to move upward or downward, the lower end surface of the pushing member 7 will slide on the surface of the gear member 12 at this time, so that the pushing member 7 cannot continue to drive the gear member 12 to rotate, and keep the rotating shaft 11 only capable of rotating 90° clockwise and counterclockwise and then stopping.

[0021] Step 4: Drive the gear member 12 on the rotating shaft 11 to rotate through the first tooth 65 on the pushing member 7, so that the driving member 5 on the rotating shaft 11 rotates. The gear member 12 is provided with a second tooth 13, and the first tooth 65 and the second tooth 13 are in meshing contact.

[0022] Step Five: The driving member 5 rotates 90°, pushing the sealing member 6 upward to keep a separation between the sealing member 6 and the holding member 4. The lead water flows down between the sealing member 6 and the holding member 4, and at the same time, the driving member 5 closes the blocking port 64 on the blocking member 8. Since the driving member 5 is in a long strip shape, when the driving member 5 rotates to the vertical state, the driving member 5 at this time will push the sealing member 6 and close the blocking port 64 on the blocking member 8. When the driving member 5 rotates to the horizontal state, the driving member 5 will not contact the blocking member 8 and the sealing member 6 at this time, so the blocking port 64 will be opened at this time, and the lead water in the active area 28 will flow down from the blocking port 64.

[0023] Step Six: After the second forming roller 15 continues to rotate, the pushing member 7 moves downward, keeping the first tooth driving the gear member 12 to rotate in the reverse direction, so that the rotating shaft 11 also rotates in the reverse direction, keeping the driving member 5 rotating 90° in the reverse direction. After the sealing member 6 loses the external force of the driving member 5, it resets, and the driving member 5 no longer closes the blocking port 64, and the lead water flows down from the blocking port 64 to reach between the first forming roller 14 and the second forming roller 15. When the second forming roller 15 rotates continuously, the driving member 5 will rotate clockwise and counterclockwise continuously, and the rotation angle is 90°. Keep the sealing member 6 and the holding member 4 open and closed at intervals for a certain time, so that the lead water discharges a certain mass within a certain time, ensuring that the quality of each grid is consistent and the lead water is not wasted. At the same time, the channel for the lead water to flow down is automatically opened and closed.
