Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery repair, and particularly to a device for removing faults of returned lead-acid batteries. Background Art

[0002] A lead-acid battery is formed by connecting several single cells in series; in addition to physical damage (such as swelling of the outer shell, severe damage, battery leakage, deformation of the terminal post and electrode plate, etc.), the reasons for the failure of lead-acid batteries are also due to sulfation and water shortage caused by the structure of the lead-acid battery itself, too high operating environment temperature, improper charge and discharge current, etc.

[0003] (1) Corrosion of the negative bus bar

[0004] Corrosion of the negative bus bar is a failure mode caused by the inherent structure of valve-regulated lead-acid batteries. Since the electrolyte of valve-regulated lead-acid batteries can only wet the bottom of the ear, it is difficult to reach the upper part of the ear and the bus bar. The bus bar and the connection part of the terminal post above the separator are in an oxygen atmosphere and are prone to corrosion. When the corrosion is severe, the bus bar will be pulverized, resulting in a decrease in its mechanical strength and fracture under stress, causing battery open-circuit failure.

[0005] (2) Sulfation of the electrode plate

[0006] Valve-regulated lead-acid batteries must avoid over-discharge, especially deep discharge. If the lead-acid battery is undercharged for a long time or stored in a semi-discharged state for a long time, hard and large PbSO4 crystals will be formed on the positive and negative electrode plates. The long-term existence of PbSO4 will lead to a decrease in the battery discharge capacity. With the accumulation of PbSO4, the porosity of the electrode plate gradually decreases, which in turn causes an increase in the internal resistance of the battery, a decrease in the electrode reaction rate, and a gradual reduction in the service life of the battery.

[0007] (3) Water loss and corrosion of the positive electrode plate

[0008] During the charging process of lead-acid batteries, water decomposition occurs at the positive electrode. Under normal conditions, due to the oxygen absorption technology of the negative electrode of lead-acid batteries, water is not lost inside the battery. However, overcharging of the battery will accelerate the water decomposition reaction, a large amount of O2 is released at the positive electrode, and a large amount of H2 is released at the negative electrode. The continuously generated gas causes an increase in the internal pressure of the lead-acid battery, and it needs to be exhausted through the exhaust valve, which will lead to a reduction in the water content in the electrolyte, resulting in an increase in the sulfuric acid concentration in the electrolyte, and further promoting the corrosion of the positive electrode plate. Relevant data shows that when the water loss reaches 3.5 mL / Ah, the capacity of the lead-acid battery drops below 75%; when the water loss reaches 25%, the battery will completely fail.

[0009] Currently, for the removal of defective lead-acid batteries in return shipments, the positive and negative electrodes are manually removed from the cell. The positive and negative electrodes together are called the electrode assembly. Using manual labor is labor-intensive, and there are relatively dangerous corrosive gases inside, which endanger the physical health of personnel and result in low work efficiency. Summary of the Invention

[0010] The purpose of the present invention is to provide a device for removing defects in returned lead-acid batteries to solve the problems raised in the above-mentioned background technology.

[0011] To solve the above technical problems, the present invention provides the following technical solution: A device for removing defects in returned lead-acid batteries includes a mounting plate fixed on a lifter. A driving member is vertically fixed in the middle of the bottom end of the mounting plate, and connecting rods are vertically fixed at the four corners of the bottom end of the mounting plate. A bottom rod is cross-connected between the connecting rods. A boss is fixed at the output end of the driving member, and the boss slides up and down between the connecting rods. A cutting and cleaning assembly is provided between the outer side of the bottom rod and the boss.

[0012] Among them, the lifter drives the device to move downward. Then, the driving member expands and contracts to drive the boss to move downward. The downward movement of the boss triggers the cutting and cleaning assembly to move downward to cut off the defective electrode assembly and clean the inside.

A telescopic member II is connected between the middle of the length abutting plate and the bottom end of the top plate. The outer sides of the length abutting plate and the width abutting plate are in contact with the cutting and cleaning assembly.

[0014] Further, the cutting and cleaning assembly includes a cross fixed on the bottom rod. Rotating rods are rotatably connected to the ends of the cross. The top ends of the rotating rods are in contact with the outer sides of the length abutting plate and the width abutting plate. Width plates and length plates are vertically fixed at the bottom ends of the rotating rods corresponding to the positions of the width abutting plate and the length abutting plate respectively.

[0015] Further, rollers that are in contact with the outer sides of the width abutting plate and the length abutting plate are rotatably connected to the top of the rotating rod.

[0016] Further, chamfers are provided on one side of the bottom of the width plate and the length plate. Storage grooves are provided above the chamfers on one side of the bottom of the width plate and the length plate.

[0017] Further, a push plate is slidably connected inside the storage groove. Trigger plates are rotatably connected to the other side of the bottom of the width plate and the length plate. A driving structure is connected between the trigger plate and the push plate.

[0018] Furthermore, the driving structure includes a hinge connecting rod I rotatably connected to the push plate and a hinge connecting rod II rotatably connected to the trigger plate. The lower parts of the hinge connecting rod I and the hinge connecting rod II are connected to the inner sides of the bottoms of the width plate and the length plate through a rotating shaft, and a return spring is connected between the ends of the hinge connecting rod I and the hinge connecting rod II.

[0019] Furthermore, a sliding groove for the sliding of the rotating shaft is formed in the middle of the hinge connecting rod I.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: By using the cutting and cleaning assembly, it can replace manual labor to cut off the faulty electrode assembly, reduce the labor intensity of workers, and can perform timely cleaning to improve work efficiency.

[0037] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present invention provides a technical solution: A device for removing faults of returned lead-acid batteries includes a mounting plate 100 fixed on a lifter. The lifter is a structure that can move up and down, such as a lift, and is used to drive the entire device to move up and down. A driving member 200 is vertically fixed in the middle of the bottom end of the mounting plate 100. The driving member 200 uses an additional cylinder, and the specific model is determined according to actual use. Connecting rods 300 are vertically fixed at the four corners of the bottom end of the mounting plate 100. A bottom rod 400 is cross-connected between the connecting rods 300. A boss 500 is fixed at the output end of the driving member 200. The boss 500 slides up and down between the connecting rods 300. A removal and cleaning assembly 600 is provided between the outer side of the bottom rod 400 and the boss 500;

[0039] Among them, the lifter drives the device to move downward, and then the driving member 200 expands and contracts to drive the boss 500 to move downward. The downward movement of the boss 500 triggers the removal and cleaning assembly 600 to move downward to remove the faulty electrode assembly and clean the inside.

[0040] During use, the lifter drives the entire device to move downward. When the cutting and cleaning component 600 contacts the top of the faulty electrode component, the driving member 200 expands and contracts at this time. The expansion and contraction of the driving member 200 drives the boss 500 to move downward. The downward movement of the boss 500 triggers the cutting and cleaning component 600 to move downward to cut off the faulty electrode component and clean the interior. After that, the lifter operates to move the entire device upward, and the work can be completed.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the boss 500 includes a top plate 501 fixed to the output end of the driving member 200. A width contact plate 502 is rotatably connected to the top plate 501 along the width direction. A telescopic member I 503 is connected between the middle of the width contact plate 502 and the bottom end of the top plate 501. The telescopic member I 503 uses a hydraulic cylinder (it is recommended to use a telescopic member with strong power). A length contact plate 504 is rotatably connected to the top plate 501 along the length direction. A telescopic member II 505 is connected between the middle of the length contact plate 504 and the bottom end of the top plate 501. The telescopic member II 505 also uses a hydraulic cylinder, which belongs to the prior art and will not be elaborated here. The outer sides of the length contact plate 504 and the width contact plate 502 contact the cutting and cleaning component 600.

[0042] During use, the inclination positions of the width contact plate 502 and the length contact plate 504 on the top plate 501 can be changed by the expansion or retraction of the telescopic member I 503 and the telescopic member II 505, so as to better clamp the electrode component or perform relevant cleaning work.

[0043] Please refer to Figure 1 and Figure 6 , the cutting and cleaning component 600 includes a cross 601 fixed to the bottom rod 400. Rotating rods 602 are rotatably connected to the ends of the cross 601. The top ends of the rotating rods 602 contact the outer sides of the length contact plate 504 and the width contact plate 502. Vertically fixed width plates 603 and length plates 604 are respectively provided at the bottom ends of the rotating rods 602 corresponding to the positions of the width contact plate 502 and the length contact plate 504.

[0044] During use, after the width plate 603 and the length plate 604 are inserted into the electrode component groove, the driving member 200 drives the length contact plate 504 and the width contact plate 502 to move downward. The length contact plate 504 and the width contact plate 502 contact the top ends of the rotating rods 602, causing the upper parts of the rotating rods 602 to rotate outward and the bottom parts of the rotating rods 602 to rotate downward at the same time, thereby clamping the electrode component. After that, as the lifter moves upward, the task of cutting off the electrode component can be completed.

[0045] Please refer to Figure 6 and Figure 7, a roller 605 which is rotatably connected to the top of the rotating rod 602 and contacts the outer sides of the width abutting plate 502 and the length abutting plate 504 is provided.

[0046] During use, by using the roller 605, the friction when the top end of the rotating rod 602 contacts the outer sides of the length abutting plate 504 and the width abutting plate 502 can be conveniently reduced.

[0047] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 , chamfers are provided on one side of the bottom of the width plate 603 and the length plate 604, and a material storage groove 611 is provided at a position above the chamfer on one side of the bottom of the width plate 603 and the length plate 604.

[0048] During use, by using the chamfers, the width plate 603 and the length plate 604 can be conveniently inserted into the corresponding electrode assembly grooves, and by using the material storage groove 611, the residual materials in the electrode assembly grooves can be conveniently cleaned and stored.

[0049] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 , a push plate 612 is slidably connected to the inside of the material storage groove 611, a trigger plate 614 is rotatably connected to the other side of the bottom of the width plate 603 and the length plate 604, and a driving structure is connected between the trigger plate 614 and the push plate 612.

[0050] During use, when the trigger plate 614 contacts the electrode assembly, the trigger plate 614 rotates upward, and the upward rotation of the trigger plate 614 drives the push plate 612 to slide into the inside of the material storage groove 611 through the driving structure. The sliding of the push plate 612 inside the material storage groove 611 can be realized by a structure combining a slider and a chute, which belongs to the prior art and will not be elaborated here. When the electrode assembly is lowered, the trigger plate 614 rotates downward and drives the push plate 612 to move outward from the material storage groove 611 through the driving structure, so as to complete the cleaning of the inside of the material storage groove 611.

[0051] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 , the driving structure includes a hinge connecting rod I 613 rotatably connected to the push plate 612 and a hinge connecting rod II 615 rotatably connected to the trigger plate 614. The lower parts of the hinge connecting rod I 613 and the hinge connecting rod II 615 are connected to the inner sides of the bottoms of the width plate 603 and the length plate 604 through a rotating shaft, and a return spring 617 is connected between the ends of the hinge connecting rod I 613 and the hinge connecting rod II 615.

[0052] During use, the trigger plate 614 rotates upward to drive the hinge connecting rod II 615 to rotate around the rotating shaft. The end drives the hinge connecting rod I 613 to rotate towards the trigger plate 614 through the return spring 617. The rotation of the hinge connecting rod I 613 drives the push plate 612 to slide into the storage tank 611. When the trigger plate 614 is attached to the width plate 603 and the length plate 604, the space inside the storage tank 611 is vacated. When the width plate 603 and the length plate 604 move upward, the inner side of the electrode assembly groove can be scraped and enter the storage tank 611. The residues on the inner side of the electrode assembly groove initially move along with the bottom of the width plate 603 and the length plate 604. When the residues continue to move upward, they come into contact with the storage tank 611. Since the storage tank 611 has a receiving space, they enter the storage tank 611. When the electrode assembly is lowered, the trigger plate 614 returns to its original position, and the push plate 612 clears the residual materials in the storage tank 611. The trigger plate 614 can act as barbs during the process of clamping the electrode assembly to prevent the electrode assembly from slipping.

[0053] Please refer to Figure 8 , a sliding groove 616 for the sliding of the rotating shaft is provided in the middle of the hinge connecting rod I 613. By using the sliding groove 616, the push plate 612 can slide horizontally when sliding.

[0054] Note: By controlling the expansion and contraction of the telescopic member I 503 or the telescopic member II 505, the bottom ends of the width plate 603 or the length plate 604 can be brought into contact, and thus the residual materials at the bottom of the electrode assembly can be removed.

[0055] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
