Description

Technical Field

[0001] This invention relates to the field of lead-acid battery production equipment technology, and in particular to a lead-acid battery terminal anti-acid oil coating device and coating method. Background Technology

[0002] Lead-acid batteries (VRLA) are rechargeable batteries whose electrodes are primarily made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.

[0003] When adding sulfuric acid to lead-acid batteries, there is a risk of sulfuric acid solution splashing onto the terminals. This splashed sulfuric acid solution can corrode the terminals, affecting not only their appearance but also their conductivity. Therefore, before adding sulfuric acid solution, the terminals of lead-acid batteries need to be protected by applying an acid-resistant oil.

[0004] In existing technologies, the application of anti-acid oil relies solely on manual labor, which is not only time-consuming and labor-intensive, reducing work efficiency, but also results in uneven application, affecting the anti-acid effect. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-acid oil coating device and method for lead-acid battery terminals, which replaces the traditional manual application of anti-acid oil with a machine, saving considerable time and labor, greatly improving work efficiency, and ensuring uniform coating to guarantee the anti-acid effect, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An anti-acid oil coating device for lead-acid battery terminals includes a conveying mechanism, a limiting mechanism, a blocking mechanism, a lifting mechanism, and a coating mechanism. The limiting mechanism is connected to the conveying mechanism, the blocking mechanism is connected to one end of the conveying mechanism, and a gantry is connected to the conveying mechanism. The lifting mechanism is connected to the gantry, and the coating mechanism is connected to the lifting mechanism. The coating mechanism includes a base, an oil cavity is provided in the base, and a through hole is provided at the bottom of the base, which communicates with the oil cavity. Two soft oil-absorbing blocks are connected in the through hole, and the lifting mechanism drives the oil-absorbing blocks to approach or move away from the conveying mechanism.

[0007] A further improvement of the present invention is that the conveying mechanism is a belt conveyor; the limiting mechanism includes two sets of columns, which are symmetrically connected to the frame on both sides of the belt conveyor, and a limiting rod is connected to each set of columns. The limiting rod is located above the conveyor belt of the belt conveyor; the inlet end of the limiting rod is bent toward both sides of the belt conveyor to form an flared shape, and the outlet ends of the two limiting rods are parallel to each other.

[0008] A further improvement of the present invention is that the blocking mechanism includes two first cylinders, which are symmetrically connected to the frames on both sides of the belt conveyor, and the power output end of the first cylinder is connected to a stop block.

[0009] A further improvement of the present invention is that the lifting mechanism includes a back plate, which is connected to the gantry frame. A vertically arranged second cylinder is connected to the top of the back plate, and the power output end of the second cylinder is connected to a lifting plate. The lifting plate is connected to the back plate via a linear slide rail.

[0010] A further improvement of the present invention is that the base is connected to the back plate, and the top of the oil cavity is provided with an oil injection hole, which is connected to the oil supply device.

[0011] A further improvement of the present invention is that the soft oil-absorbing block is a sponge, the sponge is adhered to the through hole, and the bottom end of the sponge protrudes from the base.

[0012] A further improvement of the present invention is that the oil supply device includes an oil tank, an oil pump connected to the oil tank, a connector connected to the oil filling hole, and the oil pump connected to the connector through a pipeline.

[0013] A further improvement of the present invention is that the bottom of the oil cavity between the through holes is a raised cone shape.

[0014] A method for applying anti-acid oil to lead-acid battery terminals, using the aforementioned anti-acid oil application device for lead-acid battery terminals, includes the following steps: Step 1: This device is used with a PLC controller and proximity switches. The operator manually or by using a robotic arm, places the lead-acid battery on the belt conveyor. The length of the lead-acid battery is along the running direction of the belt conveyor. Under the conveyor belt, the lead-acid battery enters between the two limit bars. S2. When one end of the lead-acid battery passes through the space between the limit rods, the first cylinder extends and the baffle blocks the lead-acid battery. The two baffles and the two limit rods restrict the lead-acid battery. At this time, the two terminals on the lead-acid battery correspond to the two sponges. S3. When the oil pump is working, a small amount of acid-resistant oil enters the oil chamber from the oil tank and is absorbed and stored in the sponge. S4. The second cylinder extends, the base moves downward, the sponge is slightly squeezed, and the anti-acid oil is applied to the wiring terminals. S5. After the coating is completed, the first and second cylinders retract, and the belt conveyor continues to work, transporting the lead-acid batteries coated with anti-acid oil to the next acid injection process.

[0015] The beneficial effects of this invention are: The anti-acid oil coating device and coating method for lead-acid battery terminals of the present invention replaces the traditional manual application of anti-acid oil with a machine, which saves a lot of time and labor, greatly improves work efficiency, and ensures uniform coating and anti-acid effect.

[0016] The present invention relates to an anti-acid oil application device and method for lead-acid battery terminals. When applying anti-acid oil, two baffles and two limiting rods restrict the lead-acid battery, ensuring that the sponge and the terminal are aligned vertically, thus making the application more accurate.

[0017] The anti-acid oil coating device and coating method for lead-acid battery terminals of the present invention have a raised cone-shaped bottom in the oil cavity between the through holes to ensure that the anti-acid oil can flow smoothly onto the sponge. Attached Figure Description
