Description

Technical Field

[0001] This invention belongs to the field of battery welding technology, specifically relating to a terminal for automatic welding of small-diameter lead-acid batteries. Background Technology

[0002] Terminal welding is a crucial step in lead-acid battery assembly. Automated terminal welding offers significant advantages over manual welding. Automated welding produces terminals with far superior strength, consistency, and stability compared to manual welding. It also eliminates the need for solder wire and soldering irons, making the production process more environmentally friendly and healthier. Manual terminal welding suffers from inconsistent solder wire amounts and soldering iron wattage, leading to variations in weld size and affecting weld quality. Different operators also produce terminals with varying heights and weld areas. Furthermore, personnel changes require significant time and practice for new operators, further impacting weld quality. Automated terminal welding eliminates the need for solder wire and soldering irons, reducing production costs. Compared to manual welding, automated welding utilizes argon arc welding, achieving greater consistency in weld height and area, resulting in more stable weld quality. Finally, automated terminal welding is far more efficient than manual welding, significantly improving both efficiency and production capacity. Summary of the Invention

[0003] To achieve the above objectives, the technical solution of the present invention is as follows: The terminal structure used in traditional manual welding cannot meet the needs of automated equipment. By using this new type of terminal structure, the machine can automatically feed, pick up, place, and weld terminals, thus realizing the requirements of automated production. The terminal and the battery terminal groove fit more stably, avoiding terminal skewing during automatic terminal picking and placing. At the same time, a step is added to the bottom of the terminal to make the connection between the terminal and the positive and negative terminals of the battery more secure. A glue flow hole is added in the middle of the terminal so that the colored glue can flow into the glue tank completely, achieving complete sealing of the glue tank.

[0004] The technical solution of this utility model: This novel structural terminal is a new type of structural terminal suitable for automatic terminal welding equipment. Inward grooves are designed on both sides of the middle of the terminal to avoid interference with the glue tank when placing the terminal; a boss is designed at the bottom of the central hole of the terminal to ensure that the terminal is not skewed and to make the welding of the terminal post to the battery more secure and durable; small bosses are designed at the tail of the central hole of the terminal to ensure that the terminal is tightly and automatically positioned with the vibration table, realizing automatic terminal feeding, automatic gripping, automatic placement, and automatic welding, thus automating the terminal welding production process, improving the reliability and consistency of terminal welding quality, and increasing production efficiency; a glue flow hole is designed in the middle of the terminal to ensure that the colored glue completely fills the terminal and the glue tank when dripping colored glue, ensuring the sealing of the battery colored glue.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0006] 1) Using this new type of terminal structure can eliminate the terminal misalignment caused by interference between the old type of terminal and the glue tank, which prevents the automatic placement of terminals during production;

[0007] 2) The terminal hole of this new structure has a boss at the bottom center, which can ensure a more secure weld between the pole and the terminal during welding;

[0008] 3) Using this new type of terminal structure, the machine can automatically position and transport terminals, grasp terminals, place terminals, and weld terminals, eliminating manual operation for welding terminals and realizing the requirements for automated production of welded terminals;

[0009] 4) Using this new type of terminal structure can ensure the consistency of terminal welding area and welding height, as well as the stability and consistency of welding quality;

[0010] 5) Using this new type of terminal structure eliminates the need for solder wire and soldering iron, saving production costs and improving production efficiency;

[0011] 6) Using this new type of terminal structure can avoid the problem of color glue blockage, improve the flowability of color glue, and ensure the sealing of the color glue tank. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] Example: Figure 1 As shown, the terminal presents a "Z" shaped structure, consisting of a small rectangular block 103 at the tail of the terminal center hole of the positioning part connected to the vibration table slot, a terminal center hole boss 102 and a terminal center hole (104) connected to the battery pole, and a terminal top output end 105 connected to the robot arm.

[0020] Furthermore, grooves 101 are provided on both sides of the terminal.

[0021] Furthermore, the adhesive flow hole 106 is disposed in the middle of the terminal.

[0022] Furthermore, the small rectangular block 103 is located at the tail of the terminal center hole, which enables automatic terminal positioning and conveying.

[0023] Furthermore, the central hole boss 102 is disposed at the bottom of the terminal central hole.

[0024] Furthermore, the output terminal 105 is located at the front end of the terminal to facilitate the robotic arm to grasp and place the terminal.

[0025] Working Principle: When using this automatic terminal welding machine, the pre-prepared terminal is placed in a circular, multi-layered vibrating tray. The vibrating tray machine is started to automatically vibrate the terminal. The terminal slowly vibrates into the circular roller track of the vibrating tray. The small rectangular block 103 at the tail of the terminal's center hole and the front and rear sides of the circular vibrating table slot automatically limit and position the terminal, ensuring that the terminal is not skewed, overlapped, or disordered during the delivery process. The terminal is then automatically and orderly delivered. After the terminal is automatically delivered to its position, the robot arm automatically grabs the top output end 105 of the terminal and then automatically places it downwards along the terminal's center hole 104 at the position of the cylindrical battery terminal 107. This ensures that the bottom protrusion 102 of the terminal's center hole fits tightly with the battery terminal 107. When the machine automatically places the terminal, the grooves 101 on both sides of the terminal can effectively avoid interference with the battery glue tray steps, ensuring that the battery terminal is placed accurately and without skew. Then, the machine automatically welds the terminal. After the terminal is welded, the colored glue is automatically dripped. The colored glue can fill the battery glue tray through the glue flow hole 106 in the middle of the terminal, achieving a sealing effect for the colored glue tray.

[0026] It should be noted that the above content merely illustrates the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, various improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
