Description

Technical Field

[0001] This utility model belongs to the technical field of lead-acid battery production equipment, specifically relating to a separator unwinding machine used in the lead-acid battery encapsulation process. Background Technology

[0002] In the production process of lead-acid batteries, the encapsulation process is a crucial step. Existing encapsulation machines complete the electrode group encapsulation by wrapping separators around the plates and stacking the positive and negative plates according to the designed quantity. The separators are initially supplied in rolls, and the unwinding machine unwinds them before feeding them into the encapsulation machine for wrapping. However, due to the limited operating height for manual separator replacement, the separator unwinding machine, which is currently widely used, operates with the separator only about 10cm above the ground. This height limitation easily leads to the following problems: First, the unwinding machine is prone to accidental contact by personnel, causing danger; second, the hanging part of the separator after unwinding is easily exposed to ground contaminants, affecting battery performance; third, after the separator hangs down and touches the ground, the light sensor's sensing distance becomes inaccurate, causing a mismatch between the operating speeds of the unwinding machine and the encapsulation machine, thus affecting encapsulation quality and production cycle time.

[0003] Furthermore, existing diaphragm unwinding machines present operational inconveniences when replacing diaphragms. Due to limitations in manual operating height, the operational safety and stability of diaphragm unwinding machines need improvement.

[0004] Therefore, there is an urgent need for a new type of separator unwinding machine design to solve the above problems, improve the efficiency and safety of the encapsulation process, and provide strong support for the automated production of lead-acid batteries. Utility Model Content

[0005] To address the problems of insufficient operating height and lack of flexible height adjustment function in the aforementioned separator unwinding machines, which lead to poor operational safety and poor encapsulation quality, this utility model provides a separator unwinding machine for the lead-acid battery encapsulation process, which has a height adjustment function.

[0006] The technical solution of this utility model is: a separator unwinding machine for the lead-acid battery encapsulation process, comprising a base, a frame, an unwinding wheel, a disc, a photosensitive system, and a control system. The frame is mounted on the base, the unwinding wheel is mounted on the disc, and the photosensitive system is electrically connected to the control system. The machine is characterized by further including a pneumatic rod device. The frame consists of a vertical rod and a diagonal rod with one end hinged to the vertical rod. The photosensitive system is mounted on the top of the vertical rod. The other end of the diagonal rod is connected to the disc. The diagonal rod is hinged to the telescopic end of the pneumatic rod device.

[0007] In the technical solution of this utility model, the gas spring device is hinged to the base.

[0008] The pneumatic rod device in the technical solution of this utility model includes a cylinder and a cylinder bracket; the piston rod of the cylinder is hinged to the inclined rod via the cylinder bracket on the inclined rod; the cylinder is hinged to the base via the cylinder bracket on the base.

[0009] In the technical solution of this utility model, one end of the inclined straight rod is hinged to the vertical rod via a rotating shaft.

[0010] The photosensitive system described in the technical solution of this utility model includes a light emitter and a light receiver, which are mounted on the top of a vertical rod via a connecting rod and are located above the discharge end.

[0011] In the technical solution of this utility model, the connecting rod is a horizontal straight rod.

[0012] The base described in the technical solution of this utility model is a plate-shaped base.

[0013] The base described in the technical solution of this utility model is a rectangular plate or a circular plate.

[0014] In the technical solution of this utility model, the vertical rod is a square rod or a round rod; the bottom of the base is provided with a fixed support foot for fixing the vertical rod; the inclined rod is a flat rod or a round rod.

[0016] Compared with the prior art, the present invention provides a separator unwinding machine for the lead-acid battery packaging process, which has the following advantages:

[0017] 1. By adding a pneumatic rod device to the existing unwinding machine, the operating height of the unwinding machine is effectively increased, so that the height of the partition plate above the ground reaches more than 120cm when the unwinding machine is running. This avoids the danger of personnel accidentally touching the unwinding machine when it is rotating and unwinding, and significantly improves the safety of operation.

[0018] 2. This height design also ensures that the hanging part of the partition after unwinding will not come into contact with ground contaminants, while ensuring the accuracy of the photosensitive distance. It also achieves precise matching of the running speed of the unwinding machine and the sealing machine, effectively improving the sealing quality and production cycle time.

[0019] 3. When replacing the partition, the height of the unwinding machine can be lowered, which facilitates manual operation, solves the problem of inconvenience of manual operation in the existing technology, and improves the efficiency and accuracy of partition replacement;

[0020] 4. After replacement, the height can be increased, which improves the operational stability of the unwinding machine, avoids accidental displacement or tipping of the partition during the sealing process, and ensures the smooth progress of the sealing process;

[0021] 5. By using a photosensitive interlock to control the unwinding speed of the unwinding machine, precise control of the unwinding speed is achieved, effectively preventing the problem of unwinding speed being too fast or too slow, and further improving the packaging quality and production efficiency.

[0022] This invention features adjustable separator running height, improved operational safety, and effective improvement in encapsulation quality and production cycle time. It is mainly used in the encapsulation process of lead-acid batteries. Attached Figure Description

[0025] To more clearly illustrate the technical solution of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This utility model discloses an embodiment of a separator unwinding machine for lead-acid battery encapsulation process, comprising a base 1, a frame 2, an unwinding wheel 3, a disc 4, a pneumatic rod device 5, a photosensitive sensor system 6, and a control system 7. The base 1, unwinding wheel 3, disc 4, photosensitive sensor system 6, and control system 7 are the same as those in existing separator unwinding machines and are used in conjunction with an encapsulation machine 9.

[0027] The base 1 is a rectangular plate-shaped base, or it can be a circular plate-shaped base. The bottom of the base 1 is provided with fixed support feet for fixing the vertical rod.

[0028] The frame 2 consists of a vertical rod and a diagonal rod hinged at one end to the vertical rod. The vertical rod can be square or round. The lower end of the vertical rod is fixed to a fixed support foot at the bottom of the base 1. The diagonal rod can be flat or round. One end of the diagonal rod is hinged to the lower middle part of the vertical rod via a pivot, allowing the diagonal rod to rotate clockwise and counterclockwise around the vertical rod.

[0029] The unwinding roller 3 is mounted on a disc 4, which supports the partition. The disc 4 is fixed to the other end of the inclined straight rod. The unwinding roller 3 has a split structure, which can be opened and closed. When the unwinding roller is closed, its diameter is smaller than the inner diameter of the partition, making it easier to remove the partition. When the unwinding roller is opened, its diameter is slightly larger than the inner diameter of the partition, supporting the inner circle of the partition and ensuring that the partition 8 and the unwinding roller do not move relative to each other. When the unwinding roller 3 rotates, it unwinds and conveys the partition 8 to the sealing machine 9.

[0030] The photosensitive system 6 includes a light emitter and a light receiver, mounted on the top of the vertical rod via a connecting rod and located above the discharge end. It is used to detect the sag height of the partition 8 and feed the signal back to the control system 7. The connecting rod is a horizontal straight rod. The photosensitive system 6 is electrically connected to the control system 7.

[0031] The pneumatic rod device 5 includes a cylinder and a cylinder support. The piston rod of the cylinder is hinged to the inclined rod via the cylinder support on the inclined rod, and the cylinder is hinged to the base 1 via the cylinder support on the base 1, allowing it to rotate. This allows the disc 4 to rotate clockwise and counterclockwise around the vertical rod, achieving height adjustment during the operation of the partition 8. The air inlet and outlet of the cylinder are respectively connected to a pressure regulating valve and an air filter. When the cylinder is inflated, the piston rod supports the inclined rod to rise; when the cylinder is deflated, the inclined rod lowers.

[0032] The control system 7 includes a controller and an operating interface. The controller automatically adjusts the rotation speed of the unwinding reel 3 based on the signal fed back by the photosensitive system 6. The operating interface is equipped with a safety start switch, a speed adjustment knob, an unwinding reel opening / retracting knob, and a height adjustment knob. The height adjustment knob controls the height of the unwinding machine via the pneumatic rod device 5.
