Description

Technical Field

[0001] This utility model relates to the field of AGM battery cover production technology, and in particular to an AGM battery cover pressing equipment. Background Technology

[0002] AGM batteries use pure sulfuric acid aqueous solution as electrolyte. Compared with batteries of the same specifications, although they are more expensive, they have advantages such as longer service life, higher capacity stability throughout the entire service life, more reliable low-temperature performance, lower environmental pollution risk, and simpler maintenance.

[0003] During the production process, AGM batteries need to be installed inside a battery case. The battery case serves to secure and seal the battery, preventing moisture and impurities from entering. The battery case cover typically integrates an explosion-proof diaphragm and a pressure relief valve. When the internal pressure of the battery rises to a certain value, the explosion-proof diaphragm opens to release pressure, reducing the risk of explosion. Therefore, the battery case is a crucial component of the battery.

[0004] Chinese utility model patent application CN202111033467.2 describes an automatic cap welding device for lithium battery assembly. This device uses a linkage mechanism to lower the welding head to weld the lithium battery directly below it. After welding, the turntable continues to rotate. During rotation, the linkage mechanism rises until the welded lithium battery reaches a designated station, where it is removed. Unwelded lithium batteries are then clamped at this clamping station. The clamping station facilitates centering and clamping of the lithium battery, saving fixing time. However, during operation, the spherical protrusion slides within a groove, and there is sliding friction between the spherical protrusion and the inner wall of the groove. Furthermore, the connecting shaft is movably inserted into the transmission disc. This results in significant friction on the spherical protrusion, easily causing the connecting shaft to shift. This intensifies friction between the connecting shaft and the transmission disc, leading to severe wear on the connecting shaft, transmission disc, and spherical protrusion, reducing the durability and service life of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide an AGM battery cover pressing device to solve the problem mentioned in the background art that the existing battery cover pressing devices suffer from severe wear during pressing, resulting in poor equipment durability and short service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an AGM battery cover pressing device, comprising a base plate, a top plate fixedly connected to the top of the base plate, a hydraulic cylinder fixedly connected to the top of the top plate, a pressure plate fixedly connected to the output end of the hydraulic cylinder, an installation box fixedly connected to the top of the base plate, a first motor fixedly connected to the inner bottom wall of the installation box, the output end of the first motor extending to the upper side of the installation box and fixedly connected to a turntable, and a clamping assembly provided on the top of the turntable;

[0007] The clamping assembly includes multiple pairs of clamping plates that are oscillating at equal angles in a ring on the top of the turntable. The clamping assembly also includes a drive mechanism located inside the mounting box. The drive mechanism includes a drive ring fixedly connected to the bottom wall of the mounting box. The top of the drive ring has a groove. The drive mechanism includes multiple first rollers that are respectively connected to the multiple pairs of clamping plates. The lifting and lowering of the first rollers can drive each pair of clamping plates to move closer or further away from each other. The bottom of the first rollers can press tightly against the top of the drive ring and the inner side wall of the groove. The groove is located directly below the pressure plate.

[0008] Preferably, the clamping assembly further includes multiple transmission mechanisms arranged in a ring at equal angles on the turntable, the multiple transmission mechanisms being connected to multiple pairs of clamping plates respectively, and the multiple first rollers being rotatably connected to the multiple transmission mechanisms respectively.

[0009] Preferably, the turntable has multiple through cavities at equal angles on its top. The transmission mechanism includes multiple mounting plates fixedly connected between the inner walls of the multiple through cavities. The top of each mounting plate has a pair of mounting cavities symmetrically formed. Two first rotating shafts are symmetrically fixedly connected between the inner walls of each pair of mounting cavities. Two rotating plates are symmetrically fixedly sleeved on the outer circumference of the two first rotating shafts. Each pair of clamping plates is symmetrically hinged to the top of the two rotating plates via a second rotating rod and a second torsion spring. Two first torsion springs are symmetrically fixedly connected between the two sides of the rotating plates and the inner walls of the mounting cavities. The transmission mechanism also includes a drive block connected to the mounting plate. The drive block is located in the middle of the two rotating plates and is tightly abutted against the two rotating plates. The side of the drive block that is tightly abutted against the two rotating plates is an inclined surface. The two inclined surfaces are respectively in the shape of an inverted V. The transmission mechanism also includes multiple lifting units connected to the bottom of the mounting plate. The multiple drive blocks are respectively connected to the multiple lifting units. The multiple first rollers are rotatably connected to the bottom of the multiple drive blocks.

[0010] Preferably, the lifting unit includes a rod fixedly connected to the bottom of the drive block, the drive block being movably inserted into the bottom end of the rod, a second elastic element being fixedly connected between the top of the drive block and the bottom of the mounting plate, a straight rod being fixedly connected to the bottom of the drive block, a connecting plate being fixedly connected to the bottom end of the straight rod, and the first roller being rotatably connected to the bottom of the connecting plate.

[0011] Preferably, the transmission mechanism further includes a swing arm rotatably connected to the bottom of the connecting plate via a third rotating rod and a third torsion spring. The first roller is rotatably connected to the bottom end of the swing arm. The advantage of this arrangement is that when friction is generated between the first roller and the top surface of the drive ring and the inner wall of the groove, the swing arm can swing slightly under the action of the third rotating rod and the third torsion spring. This avoids the force generated by friction being directly transmitted between the insertion rod and the top insertion hole of the drive block, and prevents the drive block from swinging when it moves up and down along the insertion rod, which would lead to increased wear between the two. This extends the service life of the drive block and the insertion rod, thereby effectively improving the durability of the capping device.

[0012] Preferably, the bottom of the drive block is symmetrically fixedly connected to two straight plates, which are symmetrically distributed on both sides of the swing arm. The bottom of the two straight plates is symmetrically rotatably connected to two second rollers, with the bottom of the two second rollers located above the first roller. The height difference between the bottom of the first roller and the bottom of the second roller is no more than one-third of the diameter of the first roller. The advantage of this arrangement is that, through the two second rollers located above the first roller, when the swing arm swings with a large amplitude, the second rollers will press tightly against the top surface of the drive ring and the inner wall of the groove, preventing the drive block from descending too much and causing the two clamping plates to clamp the covered battery box. This ensures that the covered battery box can be smoothly removed from the mounting plate, improving the reliability and practicality of the pressing equipment.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, by setting a first roller, a drive ring and a groove, the first roller is subjected to rolling friction when it rolls along the top surface of the drive ring and the inner sidewall of the groove. This reduces the friction force on the first roller when it rotates with the turntable, thereby avoiding excessive wear of the clamping assembly due to excessive friction, improving the durability of the pressing equipment and extending its service life.

[0015] 2. In this utility model, the lifting unit, drive block, and swing arm are designed so that when friction is generated between the top surface of the first roller and the drive ring and the inner wall of the groove, the swing arm can swing slightly under the action of the third rotating rod and the third torsion spring. This avoids the force generated by friction being directly transmitted to the insertion hole between the insertion rod and the top of the drive block, and avoids the drive block swinging when it moves up and down along the insertion rod, which would lead to increased wear between the two. This extends the service life of the drive block and the insertion rod, and thus effectively improves the durability of the capping device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 The AGM battery cover pressing equipment shown includes a base plate 1, a top plate 2 fixedly connected to the top of the base plate 1, a hydraulic cylinder 3 fixedly connected to the top of the top plate 2, a pressure plate 4 fixedly connected to the output end of the hydraulic cylinder 3, a mounting box 5 fixedly connected to the top of the base plate 1, a first motor 51 fixedly connected to the inner bottom wall of the mounting box 5, the output end of the first motor 51 extends to the upper side of the mounting box 5 and is fixedly connected to a turntable 52, and a clamping assembly 6 is provided on the top of the turntable 52.

[0026] The clamping assembly 6 includes multiple pairs of clamping plates 61 that are oscillating at equal angles in a ring on the top of the turntable 52. The clamping assembly 6 also includes a drive mechanism 63 located inside the mounting box 5. The drive mechanism 63 includes a drive ring 631 that is fixedly connected to the bottom wall of the mounting box 5. The top of the drive ring 631 has a groove 632. The drive mechanism 63 includes multiple first rollers 633 that are respectively connected to the multiple pairs of clamping plates 61. The lifting and lowering of the first rollers 633 can drive each pair of clamping plates 61 to move closer or further away from each other. The bottom of the first rollers 633 can press tightly against the top of the drive ring 631 and the inner side wall of the groove 632. The groove 632 is located directly below the pressure plate 4.

[0027] refer to Figures 1-5 The clamping assembly 6 also includes multiple transmission mechanisms 62 arranged in a ring at equal angles on the turntable 52. The multiple transmission mechanisms 62 are respectively connected to multiple pairs of clamping plates 61, and multiple first rollers 633 are respectively rotatably connected to the multiple transmission mechanisms 62.

[0028] refer to Figures 2-6 The turntable 52 has multiple through cavities at equal angles on its top. The transmission mechanism 62 includes multiple mounting plates 621 fixedly connected between the inner walls of the through cavities. A pair of mounting cavities 622 are symmetrically formed on the top of each mounting plate 621. Two first rotating shafts 623 are symmetrically fixedly connected between the inner walls of each pair of mounting cavities 622. Two rotating plates 624 are symmetrically fixedly sleeved on the outer circumference of each pair of first rotating shafts 623. Each pair of two clamping plates 61 are symmetrically hinged to the top of the two rotating plates 624 via a second rotating rod and a second torsion spring. The two sides of the rotating plates 624 and the inner walls of the mounting cavities 622 are symmetrically connected. Two first torsion springs 625 are fixedly connected. The transmission mechanism 62 also includes a drive block 626 connected to the mounting plate 621. The drive block 626 is located in the middle of the two rotating plates 624 and is tightly abutted against the two rotating plates 624 respectively. The side of the drive block 626 that is tightly abutted against the two rotating plates 624 is an inclined surface. The two inclined surfaces are inverted V-shapes respectively. The transmission mechanism 62 also includes multiple lifting units 627 connected to the bottom of the mounting plate 621. The multiple drive blocks 626 are respectively connected to the multiple lifting units 627. Multiple first rollers 633 are respectively rotatably connected to the bottom of the multiple drive blocks 626.

[0029] refer to Figures 4-6 The lifting unit 627 includes a rod 6271 fixedly connected to the bottom of the drive block 626. The drive block 626 is movably inserted into the bottom end of the rod 6271. A second elastic element 6272 is fixedly connected between the top of the drive block 626 and the bottom of the mounting plate 621. A straight rod 6273 is fixedly connected to the bottom of the drive block 626. A connecting plate 6274 is fixedly connected to the bottom end of the straight rod 6273. A first roller 633 is rotatably connected to the bottom of the connecting plate 6274.

[0030] refer to Figures 2-5 The transmission mechanism 62 also includes a rocker arm 6275 rotatably connected to the bottom of the connecting plate 6274 via a third rotating rod and a third torsion spring, and a first roller 633 rotatably connected to the bottom end of the rocker arm 6275.

[0031] Specifically, when friction is generated between the top surface of the first roller 633 and the drive ring 631 and the inner wall of the groove 632, the swing rod 6275 can swing slightly under the action of the third rotating rod and the third torsion spring. This avoids the force generated by friction being directly transmitted to the insertion rod 6271 and the top insertion hole of the drive block 626, and prevents the drive block 626 from swinging when it moves up and down along the insertion rod 6271, which would lead to increased wear between the two. This extends the service life of the drive block 626 and the insertion rod 6271, and thus effectively improves the durability of the capping device.

[0032] refer to Figure 4 and Figure 5 Two straight plates 628 are symmetrically fixedly connected to the bottom of the drive block 626. The two straight plates 628 are symmetrically distributed on both sides of the swing arm 6275. Two second rollers 629 are symmetrically rotatably connected to the bottom of the two straight plates 628. The bottom of the two second rollers 629 is located above the first roller 633. The height difference between the bottom of the first roller 633 and the bottom of the second roller 629 is no greater than one-third of the diameter of the first roller 633.

[0033] Specifically, by using two second rollers 629 located above the first roller 633, when the swing arm 6275 swings with a large amplitude, the second rollers 629 will press tightly against the top surface of the drive ring 631 and the inner wall of the groove 632, preventing the drive block 626 from descending too far and causing the two clamping plates 61 to clamp the covered battery box, ensuring that the covered battery box can be smoothly removed from the mounting plate 621, thus improving the reliability and practicality of the pressing equipment.

[0034] Two limiting plates 611 are symmetrically fixedly connected to the top of the mounting plate 621. The two limiting plates 611 can position and limit the battery box. Together with the two clamping plates 61, they can ensure the positional stability of the battery box during the pressing process. At the same time, they can ensure that the battery box and the battery cover are located directly below the pressure plate 4, ensuring that the battery cover is pressed smoothly and reliably onto the battery box.

[0035] Working principle: The battery box to be pressed is placed on top of the mounting plate 621, and the battery box is positioned between the two limiting plates 611. The battery cover is aligned and placed on top of the battery box. Then, the first motor 51 is started to drive the turntable 52 to rotate, and the turntable 52 drives multiple mounting plates 621 to rotate.

[0036] During the rotation of the mounting plate 621, multiple swing rods 6275 and multiple first rollers 633 will rotate. The first rollers 633 will roll along the top surface of the drive ring 631 and the inner wall of the groove 632. When the first rollers 633 roll to the inner wall of the groove 632, the first rollers 633 will move downward. At this time, the first rollers 633 will drive the drive block 626 downward through the swing rods 6275 and the second elastic element 6272. The two inclined surfaces of the drive block 626 will overcome the elastic force of the two first torsion springs 625 and push the bottom ends of the two rotating plates 624 in a direction away from each other. At this time, the top ends of the two rotating plates 624 will drive the two clamping plates 61 to swing in a direction close to each other until the battery box is clamped. The battery box will be clamped directly under the pressure plate 4. Then the first motor 51 will stop rotating and the hydraulic cylinder 3 will be started to push the pressure plate 4 downward until the battery cover is pressed onto the battery box. This completes the pressing process.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
