Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a battery electrode group inlet guide device. Background Technology

[0002] Lead-acid batteries are widely used in numerous fields due to their favorable operating environment, high safety performance, ease of maintenance, and ability to be stored and used in any orientation. Whether in transportation, communication, power, military, or maritime sectors, lead-acid batteries play an indispensable role. In the manufacturing process of lead-acid batteries, the first step is to fabricate electrode plates. Separators between several positive and negative electrode plates are then strung together according to capacity to form an electrode group. From the assembly of the electrode plates to the final placement into the battery box before casting and welding, processing is primarily carried out on a unit basis: the electrode group.

[0003] Most batteries have six cells, and each cell needs to hold a group of electrodes. When the electrodes are inserted into the slot, the slot is narrow, and if there is a slight misalignment, the electrodes cannot be accurately inserted into the slot cavity. Therefore, a guide device is needed to ensure that the electrodes are inserted smoothly into the slot.

[0004] Patent document CN204179173U discloses an automatic battery terminal insertion mold, comprising a mold body with several terminal insertion slots. The cross-sectional area of ​​each terminal insertion slot gradually decreases from top to bottom. A groove is provided at the lower end of each terminal insertion slot, and the groove matches the dimensions of the battery cell for positioning. However, this automatic insertion mold requires machining terminal insertion slots corresponding to the battery cells, resulting in high machining costs. Furthermore, the mold must be scrapped after wear, leading to high operating costs.

[0005] Patent document CN208889797U discloses an introductory device for battery electrode group insertion into a battery casing. The device guides the electrode group into the battery casing. The introductory device includes a hollow jacket with openings at the top and bottom and a partition plate disposed within the jacket. The partition plate is inserted into the jacket along the height direction, dividing the hollow interior of the jacket into multiple independent limiting cavities. Each limiting cavity includes at least a first cavity unit and a second cavity unit arranged at intervals. When multiple electrode groups are inserted into the battery casing, the electrode groups are divided into at least two groups and sequentially inserted into the first cavity unit and the second cavity unit. This invention divides the jacket into multiple independent limiting cavities, and then assembles the grouped electrode groups into the battery compartment in at least two separate steps. This makes it possible to directly insert a group of electrodes into the battery casing after gripping it, eliminating the need for intermediate clamps. The jacket is divided into multiple smaller limiting cavities, and rigid partitions ensure that adjacent limiting cavities do not interfere with each other. That is, after a group of electrodes is inserted into the first cavity unit, the multiple limiting cavities of the second cavity unit will not be squeezed or deformed, thus not affecting the assembly of the second group of electrodes, making assembly more labor-saving. The partitions of this device can be replaced after wear. However, this device lacks a partition to guide the opposite sides of the electrode groups at both ends, lacks positioning for the battery casing, and if the lower end of the partition is misaligned with the partition inside the battery casing, the electrode groups are easily scratched during insertion. Utility Model Content

[0006] The main purpose of this utility model is to provide a battery electrode group insertion guide device that can effectively position the battery casing, prevent the electrode group from being scratched when entering the slot, and ensure the accuracy of electrode group insertion.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A battery electrode group inlet guide device includes an annular plate. Grooves corresponding to the partition plate inside the battery casing and the left and right sidewalls of the battery casing are formed on the front and rear sides of the upper end of the annular plate. An insert plate is T-shaped, with its front and rear ends respectively inserted into the grooves on the front and rear sides. The upper part of the insert plate is detachably fixed to the annular plate. Upper guide slopes are machined on both the left and right sides of the upper end of the insert plate, and these upper guide slopes are arc-shaped transitions to the end faces of the insert plate below them. The length of the upper guide slope is greater than the length of the lower part of the insert plate. A slot is formed at the lower end of the insert plate. Lower guide slopes are machined on both the left and right sides of the lower end of the insert plate, with opposite inclinations. The distance between the upper ends of the two lower guide slopes of the insert plate is greater than the distance between the lower ends. Inner guide slopes are formed at the lower ends of the left and right walls of the slot. The inclination directions of the two inner guide slopes of the insert plate are opposite, and the distance between the upper ends of the two inner guide slopes of the insert plate is less than the distance between the lower ends. The partition plate inside the battery casing is inserted into the slot of the upper insert plate, and the left and right sidewalls of the battery casing are respectively inserted into the slots of the left and right end insert plates.

[0009] Specifically, the two upper guide slopes at the upper end of the insert plate are inclined in opposite directions, and the distance between the upper ends of the two upper guide slopes of the insert plate is less than the distance between the lower ends.

[0010] Specifically, the front and rear ends of the upper part of the insert plate are fixedly connected to the ring plate by screws.

[0011] Specifically, the surface of the insert plate that contacts the electrode group is polished.

[0012] Specifically, guide plates are fixed around the lower end of the ring plate. The guide plates are elastic, with the upper end of the guide plate inclined outward from the ring plate. The upper end of the guide plate is fixedly connected to the lower end of the ring plate. The lower end of the guide plate is machined with a guide portion that bends outward from the ring plate. The guide plate contacts the outer edge of the battery case.

[0013] Specifically, ear plates are fixed at both ends of the ring plate, and a vertical first telescopic rod is fixed at the lower end of the ear plate. The ring plate can be driven to move upward through the first telescopic rod. A mounting plate is fixed at the end of the first telescopic rod facing the battery case. The mounting plate is fixed on the slotting machine. A horizontal second telescopic rod is fixed on the side of the mounting plate facing the battery case. A pressure plate is fixed at the telescopic end of the second telescopic rod. The pressure plate can be driven to squeeze the battery case through the second telescopic rod.

[0014] Specifically, the lower ends of adjacent lower guide ramps and inner guide ramps are connected by an arc-shaped transition.

[0015] Specifically, the upper end of the lower guide slope is connected to the upper end face of the insert plate on one side in an arc transition.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting an upper guide ramp, a progressive guide channel is formed between two adjacent insertion plates, which automatically corrects the offset when the electrode group enters the slot, avoiding jamming due to slight misalignment. The cooperation between the inner guide ramp and the slot ensures that the battery case's partition and side wall are accurately inserted into the slot, realizing rapid positioning of the battery case and the guide device, reducing the need for manual adjustment.

[0018] 2. The polished contact surface of the plug significantly reduces friction between the electrode group and the device, preventing damage to the electrode group surface. The arc-shaped transition connection design eliminates sharp edges, preventing scratches to the electrode group or battery casing after slight deformation of the plug, thus extending the device's service life.

[0019] 3. The insert plate and ring plate are detachably connected by screws, allowing for individual replacement of worn parts, reducing maintenance costs and avoiding overall scrapping.

[0020] 4. The flexible guide plate design achieves flexible positioning of the battery case while reducing damage to the equipment or battery case caused by rigid contact, and adapts to slight deviations in battery cases of different sizes. The flexible guide plate adapts to the outer edge of the battery case as the ring plate descends, ensuring precise alignment between the insertion plate and the battery case and simplifying the operation process.

[0021] 5. The first and second telescopic rods work together to drive the ring plate to rise and fall and the pressure plate to clamp, so as to realize the automatic disengagement of the guide device and the fixation of the battery case, reduce manual intervention and improve production efficiency.

[0022] 6. Compared with traditional one-piece molds, this device uses a split insert plate to guide the electrode group, which reduces manufacturing costs. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1: Refer to Figures 1-6 As shown, a battery electrode group inlet guide device includes an annular plate 1, and grooves 11 corresponding to the partition plate 9 inside the battery case 8 and the left and right side walls of the battery case 8 are provided on the front and rear sides of the upper end of the annular plate 1.

[0032] The insert plate 10 is T-shaped, with its front and rear ends inserted into the grooves 11 on the front and rear sides, respectively. The upper part of the insert plate 10 is detachably and fixedly connected to the ring plate 1. Specifically, the front and rear ends of the upper part of the insert plate 10 are fixedly connected to the ring plate 1 by screws 12.

[0033] If the plug-in board 10 is damaged, the damaged plug-in board 10 can be replaced directly without replacing the whole board, resulting in low maintenance costs during use.

[0034] The upper end of the insert plate 10 has upper guide slopes 13 machined on both the left and right sides. The two upper guide slopes 13 at the upper end of the insert plate 10 have opposite inclination directions, and the distance between the upper ends of the two upper guide slopes 13 is less than the distance between their lower ends. The length of the upper guide slope 13 is greater than the length of the lower part of the insert plate 10.

[0035] By setting the upper guide slope 13, a progressive guide channel is formed between two adjacent insertion plates 10, which automatically corrects the offset when the electrode group enters the slot, avoiding jamming due to slight misalignment. Since the length of the upper guide slope 13 is greater than the length of the lower part of the insertion plate 10, it can prevent the electrode group from being scratched at the transition connection between the upper guide slope 13 and the end face of the insertion plate 10.

[0036] The lower end of the insert plate 10 has a slot.

[0037] Polishing the surface of the insert plate 10 that contacts the electrode group can reduce the friction between the electrode group and the insert plate 10 when the electrode group is inserted into the groove.

[0038] The lower end of the insert plate 10 has lower guide slopes 14 machined on both the left and right sides. The two lower guide slopes 14 are inclined in opposite directions, and the distance between the upper ends of the two lower guide slopes 14 of the insert plate 10 is greater than the distance between the lower ends.

[0039] The lower ends of the left and right slot walls of the slot are provided with inner guide slopes 15. The two inner guide slopes 15 of the insert plate 10 are inclined in opposite directions, and the distance between the upper ends of the two inner guide slopes 15 of the insert plate 10 is less than the distance between the lower ends.

[0040] The upper end of the lower guide slope 14 is connected to the end face of the insert plate 10 above it with an arc transition. The upper guide slope 13 is connected to the end face of the insert plate 10 below it with an arc transition. The arc transition connection design eliminates the sharp edges of the insert plate 10 and avoids scratching when the electrode group is inserted into the slot.

[0041] The lower ends of the adjacent lower guide slope 14 and inner guide slope 15 are connected by an arc-shaped transition, which can prevent the lower ends of the insert plates 10 on the left and right sides of the slot from forming sharp points. This prevents the lower ends of the insert plates 10 from squeezing the partition 9 inside the battery case 8 or the left and right side walls of the battery case 8 after the battery case 8 fails to be positioned, thus avoiding damage to the battery case 8.

[0042] The partition 9 inside the battery casing 8 is inserted into the slot of the upper insertion plate 10. The left and right side walls of the battery casing 8 are respectively inserted into the slots of the left and right end insertion plates 10.

[0043] When the electrode group is inserted into the slot, the ring plate 1 is positioned above the battery case 8, and the space between two adjacent insert plates 10 corresponds vertically to the cell of the battery case 8, and the upper end of the partition plate 9 and the upper ends of the left and right side walls of the battery case 8 are respectively inserted into the slots at the lower end of the insert plate 10.

[0044] By setting the inner guide slope 15, the upper end of the partition 9 and the upper ends of the left and right side walls of the battery case 8 can be smoothly inserted into the slot at the lower end of the insert plate 10, which facilitates the positioning of the battery case 8.

[0045] The robotic arm holding the electrode group moves between two adjacent insert plates 10. The robotic arm drives the electrode group downward. Under the guidance of the upper guide slope 13, the electrode group can pass through the space between the two adjacent insert plates 10 and enter the cell of the battery casing 8.

[0046] By setting the lower guide slope 14, the electrode group can be prevented from being scratched when it enters the slot after slight deformation of the lower end of the insert plate 10, thus improving the durability of the insert plate 10.

[0047] Example 2: Based on Example 1, referring to... Figure 1 , Figure 3 and Figure 5 As shown, guide plates 7 are fixed around the lower end of the ring plate 1. The guide plates 7 are elastic. The upper end of the guide plate 7 is inclined to the outside of the ring plate 1. The upper end of the guide plate 7 is fixedly connected to the lower end of the ring plate 1. The lower end of the guide plate 7 is processed with a guide portion that bends to the outside of the ring plate 1. The guide plate 7 is in contact with the outer edge of the battery case 8.

[0048] When the ring plate 1 moves downwards and approaches the upper end of the battery case 8, under the guidance of the guide part, the guide plate 7 can elastically deform in the direction of the outer side of the battery case 8. Multiple guide plates 7 can position the battery case 8, which can ensure that the insert plate 10 is accurately inserted into the separator 9 and the left and right side walls of the battery case 8, thus improving the accuracy of the electrode group entering the slot.

[0049] Example 3: Based on Example 1, referring to... Figure 1 As shown, ear plates 2 are fixed to both the left and right ends of the ring plate 1. A vertical first telescopic rod 3 is fixed to the lower end of the ear plate 2, which drives the ring plate 1 to move upward. A mounting plate 4 is fixed to the end of the first telescopic rod 3 facing the battery case 8, and the mounting plate 4 is fixed to the slotting machine. A horizontal second telescopic rod 5 is fixed to the side of the mounting plate 4 facing the battery case 8. A pressure plate 6 is fixed to the telescopic end of the second telescopic rod 5, which drives the pressure plate 6 to squeeze the battery case 8.

[0050] The first telescopic rod 3 can drive the ring plate 1 to move up and down, and the second telescopic rod 5 can drive the pressure plate 6 away from or towards the battery. After the electrode group is inserted into the slot, the second telescopic rod 5 causes the pressure plate 6 to clamp the battery, and the first telescopic rod 3 drives the ring plate 1 and the insertion plate 10 to move upward, thereby separating the ring plate 1 and the insertion plate 10 from the battery casing 8. This device facilitates the separation of the ring plate 1 and the insertion plate 10 from the battery casing 8.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
