Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to a base plate for a lead-acid battery assembly inverted adhesive sealing tool. Background Technology

[0002] In the production process of lead-acid batteries, the sealing of the battery case and cover is a crucial step in ensuring battery performance and lifespan. Traditional inverted sealing methods have several problems. Due to unavoidable dimensional deviations and flatness errors during the manufacturing process of the battery case and cover, the sealing area cannot be kept level during inverted sealing, resulting in uneven glue distribution and leading to incomplete sealing and leakage, severely impacting battery quality. Furthermore, the protruding terminals on the battery surface prevent the semi-finished battery from tightly adhering to the tooling base plate during inverted sealing, increasing operational difficulty and making it prone to terminal damage due to uneven stress, reducing production efficiency and increasing production costs. Therefore, a tooling base plate that can solve the above problems is needed to improve the quality and efficiency of inverted sealing of lead-acid batteries. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a base plate for a lead-acid battery assembly inverted sealing fixture, comprising a base plate body, a placement groove on the base plate body, a level mounted on the base plate body, terminal position holes in the placement groove, and an adjustable support structure mounted on the base plate body.

[0004] The upper part of the base plate body is provided with a battery cover, and the lower part of the battery cover is provided with a terminal protrusion. The inner diameter of the hole at the terminal position is larger than the outer diameter of the terminal protrusion.

[0005] The battery cover is provided with an adhesive groove, and the upper part of the battery cover is provided with a first terminal hole and a second terminal hole.

[0006] The battery cover has several reinforcing frames inside, and the reinforcing frames have semi-circular grooves.

[0007] A limiting block is fixedly connected to the side wall of the battery cover, and the reinforcing frame is located on the lower side of the limiting block.

[0008] The adjustable support structure includes a bolt, which is threadedly connected to a nut, and a support foot is fixedly connected to the lower part of the bolt.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: The inverted sealing fixture base plate for lead-acid batteries of this utility model can improve the sealing quality. Through the cooperation of a level and an adjustable support structure, the levelness of the base plate can be precisely adjusted, ensuring that the battery case cover seal is horizontal and that the added sealant is flat. This effectively solves problems such as poor sealing and leakage caused by uneven sealing, greatly improving the sealing quality and reliability of lead-acid batteries. Furthermore, the design of the hollowed-out terminal positions provides space for the protruding parts of the battery surface terminals, preventing the terminals from being squeezed and damaged during the inverted sealing process. This ensures that the electrical performance of the battery is not affected and improves the product qualification rate.

[0010] The tooling base plate of this utility model has a reasonable design, simple structure, and is easy to operate. It does not require complex equipment and technology, and is easy to promote and apply on the production line. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] like Figure 1-4 The illustrated base plate for a lead-acid battery assembly inverted sealing tool effectively solves the problems of uneven battery case cover sealing and inconvenient inverted sealing caused by protruding surface terminals through innovative structural design, thereby improving the quality and efficiency of lead-acid battery assembly inverted sealing and reducing production costs.

[0019] The device includes a base plate body 1, on which a placement groove 2 is provided that precisely matches the size of the battery cover 6. The shape and size of the placement groove 2 are perfectly matched with the battery cover 6, which can ensure that the battery cover 6 is placed stably and avoid displacement during the sealing process.

[0020] A high-precision level 3 is installed on the base plate body 1. The level 3 is used to observe the horizontal state of the base plate body 1. After the battery cover 6 is placed in the placement area, the adjustable support structure 5 set below the base plate body 1 can be adjusted according to the display of the level 3 to make the base plate body 1 reach a horizontal state, thereby ensuring that the battery cover seal is in a horizontal position, laying the foundation for subsequent application of slot cover adhesive and achieving a good sealing effect.

[0021] A terminal position hole 4 is provided in the groove 2 corresponding to the position of the terminal protrusion on the battery surface. The size of the terminal position hole 4 is larger than the size of the terminal protrusion. This ensures that when the battery semi-finished product 8 is inverted, the terminal protrusion can be smoothly inserted into the hole, avoiding interference between the terminal and the base plate body 1, effectively protecting the terminal from damage. At the same time, it allows the battery semi-finished product 8 to fit tightly against the base plate body 1, facilitating the glue sealing operation.

[0022] The battery cover 6 is an important component of the lead-acid battery, and its design directly affects the battery's sealing performance and electrical connection stability. The terminal protrusions are located at the bottom of the battery cover 6 and are used for electrical connection with the battery's internal terminals. The design of the terminal protrusions needs to meet certain dimensional accuracy requirements to ensure they can be smoothly inserted into the corresponding terminal holes during assembly, while avoiding damage caused by uneven force. To further protect the terminal protrusions, terminal position holes 4 are specially provided in the placement groove 2 of the base plate body 1, providing sufficient space for the terminal protrusions and preventing them from being squeezed or deformed during the inverted sealing process.

[0023] The glue tank 7 is a key structure on the battery cover 6, used to hold the glue for the cover during assembly. By pouring an appropriate amount of glue into the glue tank 7, a seal between the battery cover 6 and the battery compartment can be ensured. The design of the glue tank 7 must fully consider the flowability of the glue and its strength after curing to ensure that the battery's sealing performance reaches its optimal state after gluing.

[0024] The first terminal hole 11 and the second terminal hole 12 correspond to the first terminal post 9 and the second terminal post 10 inside the battery, respectively, and are used to realize the electrical connection between the positive and negative terminals of the battery. The size and position of the terminal holes must be precisely matched to ensure that the terminal posts can be accurately inserted and form good contact. In addition, the area around the terminal holes is usually reinforced to withstand the pressure during the reverse operation and prevent cracking or deformation.

[0025] The battery cover 6 has several reinforcing frames 13 inside, and the reinforcing frames 13 have semi-circular grooves 14.

[0026] The reinforcing frame 13 is a structural reinforcement design inside the battery cover 6, mainly used to improve the overall rigidity and pressure resistance of the cover. Since the battery may be affected by external impacts or internal pressure changes during use, the presence of the reinforcing frame 13 can effectively reduce the risk of deformation of the battery cover 6, thereby improving the reliability and service life of the battery.

[0027] A limiting block 15 is fixedly connected to the side wall of the battery cover 6, and a reinforcing frame 13 is set on the lower side of the limiting block 15.

[0028] The adjustable support structure 5 includes a bolt 52, which is connected to a nut 51 by a thread, and a support foot 53 is fixedly connected to the lower part of the bolt 52.

[0029] The adjustable support structure 5 is one of the core components of the tooling base plate. Its main function is to ensure that the battery slot cover is in an ideal horizontal state by adjusting the level of the base plate body 1. The bolt 52 and nut 51 are connected by threads, which allows the user to flexibly adjust the extension length of the bolt 52 according to actual needs, thereby changing the height and angle of the base plate body 1. The base plate body 1 has mounting holes for the bolt 52 to pass through, and the nut 51 is welded to the base plate body 1.

[0030] The support foot 53 is located below the bolt 52 and its function is to provide stable support for the entire tooling base plate. The support foot 53 is usually made of wear-resistant material and has an anti-slip design to ensure that it does not slip or tilt on the workbench.

[0031] Working principle: Place the lead-acid battery assembly inverted sealing fixture base plate on a stable workbench. Check the base plate body 1 for damage. Calibrate the level 3 to ensure it accurately displays the horizontal state of the base plate body 1. Adjust the adjustable support structure 5 to bring the base plate body 1 to an initial horizontal state. Carefully place the battery cover 6 to be sealed into the placement groove 2, ensuring that the battery cover 6 fits tightly and is accurately positioned. At this time, the sealing opening of the battery cover 6 faces upward, and the protruding part of the battery cover 6 corresponds to the terminal hole 4. Pour an appropriate amount of glue into the glue tank 7 of the battery cover 6. The amount of glue is determined according to the process requirements. Carefully invert the welded battery semi-finished product 8 onto the battery cover 6 placed in the groove 2. Accurately align the first terminal post 9 and the second terminal post 10 of the battery semi-finished product 8 with the first terminal hole 11 and the second terminal hole 12 of the battery cover 6, ensuring accurate insertion into the terminal position hole 4. At the same time, ensure that the battery semi-finished product 8 and the battery cover 6 are tightly fitted. Observe the display status of the level instrument 3. If the base plate 1 is not level, adjust the adjustable support structure 5 to make the level instrument 3 show that the base plate 1 is in a level state, ensuring that the seal of the battery cover 6 is also in a level position. Place the battery with the inverted glue seal in the specified environment for glue curing. After the glue is completely cured, remove the battery from the tooling base plate to complete the assembly and inverted glue sealing process of the lead-acid battery.

[0032] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
