[0002] Currently, in the manufacturing process of aerospace batteries, the coating and bonding of battery cells are usually completed manually or by semi-automated equipment. These operations have extremely high requirements for precision and consistency, especially in the alignment of battery strings and cover plates, uniformity of coating, and vacuum bonding. Traditional methods often cannot guarantee stable process quality. As a key step in the assembly of aerospace power systems, the quality of battery bonding directly affects the performance and reliability of the battery. Therefore, there is an urgent need for bonding equipment with higher precision and higher automation to meet the stringent quality requirements of the aerospace field.

[0003] However, existing technologies have several limitations: First, the alignment accuracy is insufficient, and reliance on manual adjustments easily leads to errors; second, the adhesive application process is not precisely controlled, resulting in poor consistency in adhesive quantity and position; third, the bonding process lacks efficient vacuum environment control and stable settling time, easily leading to air bubbles or weak bonding; and fourth, loading, unloading, and material turnover require extensive manual intervention, which is inefficient and prone to introducing contamination or damage risks. These shortcomings severely restrict the consistency and reliability of aerospace battery production.

[0004] Therefore, it is necessary to propose a flexible battery vacuum bonding device to solve the above problems. Utility Model Content

[0024] In use, the battery cells are stored on the rack 19 of one of the feeding and storage mechanisms 2, while the cover sheet is stored on the rack 19 of the other feeding and storage mechanism 2.

Two sets of linear guide rails 25 and two third linear slides 24 form a closed-loop structure, which can realize the cyclic transport of carrier circulation component 6.

Guided by the bottom of the guide ring 34, the anti-drip plate 33 drives the column 36 to move downward and stretch the spring 37. Initially, the anti-drip plate 33 is higher than the bottom of the dispensing head 12, but after the anti-drip plate 33 rotates, it is lower than the bottom of the dispensing head 12. After rotation, the groove 38 corresponds to the bottom of the dispensing head 12, thereby preventing the glue from dripping into the working area.
