[0002] The grid of a lead-acid battery is a very important component of the battery. As the collector skeleton of the electrode, the grid is responsible for conducting and collecting current to ensure uniform current distribution. The grid also supports active materials and reduces the internal resistance of the battery. When processing lead-acid batteries, the incoming grid tape needs to be wound into a roll to facilitate the subsequent production of lead-acid batteries.

[0003] Since the speed of the front end of the battery grid belt fluctuates, the winding machine needs to adjust its speed accordingly. This may cause the outer circle of the wound grid belt to become loose and unable to be wound tightly during the speed reduction process, which makes the space of the winding disk not fully utilized.

[0025] It should be noted that, in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The head and tail and the front and back in this embodiment are based on the order of the flow of the medium, that is, the medium that flows first is the front and the first, which can be understood by those skilled in the art and will not be elaborated here.

[0026] As shown in the figure, the present invention discloses a pneumatic winding auxiliary device, including an auxiliary pressing and rolling component and a constant pressure air circuit system, the auxiliary pressing and rolling component includes a swing arm 1 and a driving cylinder 3, the end of the swing arm 1 is provided with a pressure plate 2, and the swing arm 1 can be driven by the driving cylinder 3 to swing with a single degree of freedom; the constant pressure air circuit system includes a solenoid valve 13 and a relief valve 11, the solenoid valve 13 and the relief valve 11 are respectively connected to the driving cylinder 3, the solenoid valve 13 is used to control the flow of gas entering the driving cylinder 3; the relief valve 11 is used to maintain the pressure in the driving cylinder 3 constant. In this embodiment, when the driving cylinder 3 is pushed out, the swing arm 1 will press the pressure plate 2 against the surface of the grid roll, and when the driving cylinder 3 is retracted, the pressure plate 2 will swing in the opposite direction away from the grid roll. The diameter of the grid roll gradually increases as the winding progresses, so the pressure plate 2 will swing in the direction of the original grid roll as the diameter increases, but the pressure on the pressure plate 2 is constant. Therefore, when the grid roll pushes the pressure plate 2 (that is, the swing arm 1) to swing, the driving cylinder 3 as the driving source of the swing arm 1 will also produce a certain retraction. At this time, the pressure in the cylinder will increase, and the overflow valve 11 will be pushed open when the pressure increases, and the gas will be discharged to balance the pressure, ensuring that the pressure in the cylinder is constant, and then ensuring that the pressure applied by the pressure plate 2 is constant. The pressure plate 2 in this embodiment has an outwardly protruding arc surface, and the arc surface of the pressure plate 2 is tangent to the surface of the grid belt. At the tangent point, the pressure plate 2 presses the grid belt with a constant force, so that the grid belt will not be wound loose. The pressure plate 2 of the present invention presses the grid belt with a constant force. The pressure plate 2 has a relatively stable pressure output, which prevents the outer circle of the wound grid belt from being loose, thereby effectively increasing the winding amount of the winding drum, thereby improving the utilization rate of the winding drum.

[0027] In this embodiment, a support assembly is also included, the support assembly includes a support seat 4 and a support rod 5 vertically mounted on the support seat 4, the head end of the swing arm 1 is hinged to the top of the support rod 5, and the driving cylinder 3 is mounted on the support rod 5. The support assembly also includes a mounting frame 7 and a cylinder mounting clamp 16, the mounting frame 7 is mounted on the top of the support rod 5, the head end of the swing arm 1 is hinged to the top surface of the mounting frame 7; the cylinder mounting clamp 16 is mounted on the mounting frame 7 and is located below the swing arm 1, the driving cylinder 3 has a driving end and a fixed end, the fixed end is hingedly mounted on the cylinder mounting clamp 16, and the driving end is hingedly connected to the bottom surface of the swing arm 1. As shown in the figure, the head end of the swing arm 1 of this embodiment is hinged to the top surface of the mounting frame 7 through a rotating bearing 8 to ensure that the swing arm 1 can swing smoothly. The head end and the end here are the two axial ends of the swing arm 1, wherein the end that outputs the force is the end, which is understandable to those skilled in the art and will not be repeated here. In this embodiment, the fixed end of the driving cylinder 3 refers to the cylinder body of the driving cylinder 3, and the driving end refers to the push rod of the driving cylinder 3. The push rod extends out of the cylinder body for pushing out, and the push rod retracts into the cylinder body for retracting. The cylinder body of the driving cylinder 3 is hinged on the cylinder mounting clamp 16, and the push rod is hinged on the bottom surface of the swing arm 1 as shown in the figure. The hinged ends ensure that the driving cylinder 3 can push and pull the swing arm 1 smoothly.

[0028] In this embodiment, the constant pressure gas circuit system also includes a flow control valve 10 and a pressure control valve 12. The solenoid valve 13 is provided with a first passage 15 and a second passage 14. The first passage 15 and the second passage 14 are both connected to the driving gas rod. The flow control valve 10 is installed in the second passage 14 to adjust the flow of the second passage 14. The overflow valve 11 is connected to the second passage 14 and is located between the flow control valve 10 and the driving cylinder 3. The pressure control valve 12 is arranged in front of the solenoid valve 13. In this embodiment, the pressure control valve 12 mainly controls the pressure of the gas source entering the constant pressure gas circuit system, and the flow regulating valve controls the flow of gas entering the cylinder through the second passage 14. In this embodiment, the driving cylinder 3 is a double-acting cylinder, that is, the pushing action and the retracting action of the driving cylinder 3 both need to be realized by air intake, but the air intake channels are different. The first passage and the second passage 14 can be opened alternately to achieve the pushing action. Taking the pushing action as an example, Figure 5As shown, the second passage 14 takes in air, so that the push rod is pushed out. In order to ensure the continuous action of the driving cylinder 3, after the push rod is pushed into place, the flow control valve 10 is adjusted to ensure that the driving cylinder 3 maintains the current state, and the excess gas entering the cylinder body will flow out through the first passage. As the diameter of the grid roll gradually increases with the winding process, the driving cylinder 3 will also passively produce a certain retraction. At this time, the pressure in the cylinder will increase, and the overflow valve 11 will be pushed open when the pressure increases, and the gas will be discharged to balance the pressure, ensuring that the pressure in the cylinder is constant, and then ensuring that the pressure applied by the pressure plate 2 is constant. When the work stops and the pressure plate 2 is retracted, the working process is relatively simple. The air is directly ventilated into the cylinder through the first passage, so that the push rod retracts, and then the swing arm 1 is pulled to make the pressure plate 2 move away. After the push rod retracts into place, the air supply can be stopped.

[0029] In this embodiment, the constant pressure gas circuit system further includes a mounting substrate 9, which is mounted on the mounting frame 7, and the solenoid valve 13, the flow control valve 10, the relief valve 11 and the pressure control valve 12 are all mounted on the mounting substrate 9. The mounting substrate 9 is arranged to avoid the cylinder mounting clamp 16. In this embodiment, the mounting substrate 9 and the cylinder mounting clamp 16 are respectively located on two side walls of the mounting frame 7.

[0030] In this embodiment, the base is further provided with three supporting feet 6 as shown in the figure, and the three supporting feet 6 are evenly distributed along the circumference of the supporting seat 4 to improve the placement stability of the device.
