Description

Technical Field

[0001] This utility model relates to the field of mechanical processing structure technology, and in particular to a welding device. Background Technology

[0002] Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, causing fusion between molecular layers. Ultrasonic welding is widely used in automotive processing, electronics manufacturing, and medical device manufacturing. Some products require welding the workpiece to a sheet metal plate to complete the product manufacturing process. When welding the workpiece to the sheet metal plate, the sheet metal plate must first be moved to the processing position, then the workpiece to be welded is placed on the welding position on the sheet metal plate, and finally, ultrasonic welding is used to weld the workpiece to the sheet metal plate. Currently, visual positioning systems are mainly used to position the workpiece to be welded, ensuring accurate placement on the welding position on the sheet metal plate. However, visual positioning requires a certain amount of time, and if positional deviations occur after positioning, the position of the workpiece needs to be adjusted, followed by re-positioning and detection, resulting in low positioning efficiency.

[0032] In this embodiment of the welding apparatus, a support plate 1 is used to support a plate. After the plate moves onto the support plate 1, a first lifting mechanism lowers a positioning member 25, causing the positioning member 25 to abut against the plate. Then, the workpiece to be welded is placed in the receiving space, where it abuts against the plate and the side wall of the receiving space. Next, a welding member 49 moves, causing its welding end to abut against the workpiece. Finally, ultrasonic welding begins on the welding member 49. The positioning member 25 allows the receiving space to position the workpiece, and positioning is completed as soon as the workpiece is placed in the receiving space. This results in fast positioning and improved efficiency. The lifting mechanism also prevents the positioning member from affecting the movement of the plate, and the abutment between the positioning member and the plate further prevents movement and improves positioning accuracy.

The third drive component 57 is connected to the output end of the third lifting mechanism, which can drive the third drive component 57 to move up and down. The third drive component 57 is a rotary drive component, and its output end is connected to the third mounting plate 58, enabling the third drive component 57 to rotate. The fourth drive component 59 is connected to the end of the third mounting plate 58 away from the third drive component 57, thus enabling the third drive component 57 to drive the fourth drive component 59 to move in a circular motion. At least two first clamping members 591 are connected to the output end of the fourth driving member 59. The fourth driving member 59 is a clamping driving member, which can drive the two first clamping members 591 to complete clamping or opening actions. Through the cooperation of the second driving module 52, the third lifting mechanism and the third driving member 57, the clamping end of the first clamping member 591 can move towards the receiving space. The first clamping member 591 can clamp the workpiece to be welded. Through the movement of the first clamping member 591, the workpiece to be welded can enter the receiving space. Specifically, the clamping end of the first clamping member 591 is provided with a protrusion 592 protruding towards the support plate 1. The side wall of the receiving space on the positioning member 25 is provided with a groove 27. The groove 27 is arranged in the vertical direction.

Through the movement of the first clamping member 591, the first clamping member 591 can clamp the workpiece to be welded located on the conveying component. Specifically, the protrusion 592 of the first clamping member 591 can extend between the two conveying components, thereby clamping the workpiece to be welded at the middle position, thus facilitating the placement of the workpiece to be welded by the first clamping member 591.

[0041] Reference Figure 11As shown, the welding device also includes a second feeding assembly 7, which includes a third drive module 71, a seventh drive member 72, an eighth drive member 73, and a second clamping member 74.

[0042] Reference Figure 11 and Figure 12As shown, the welding device also includes a material storage assembly 8, which includes a base 81, a fourth movable plate 811, a storage rack, a support 83, a movable seat 84, a ninth drive member 82, and a tenth drive member 85.

Each storage rack is correspondingly equipped with a movable seat 84. A second clamping member 74 extends into the storage space from the top. The second clamping member 74 can move the workpiece to be welded within the storage space to the limiting groove of the conveyor. When the position of the workpiece to be welded is lower than the moving path of the second clamping member 74, the tenth driving member 85 drives the movable seat 84 to rise, allowing the second clamping member 74 to clamp the workpiece to be welded. After all the workpieces to be welded in one storage rack are removed, the fourth movable plate 811 is moved by the ninth driving component 82, so that the second clamping component 74 can remove the workpieces to be welded in the other storage rack. At this time, the empty storage rack can be loaded with workpieces to be welded, so that the conveyor can always be in a loaded state, avoiding the welding component 49 from stopping work, thereby improving the welding efficiency.

[0043] In use, the second clamping member 74 moves the workpiece to be welded in the storage space to the limiting groove of the conveying member. The conveying member drives the workpiece to be welded in the limiting groove to move. When the workpiece to be welded moves to the picking position and the plate moves onto the support plate 1, the positioning member 25 descends until the positioning member 25 abuts against the plate. Then, the first clamping member 591 drives the workpiece to be welded in the picking position to move into the accommodating space of the positioning member 25. At this time, the workpiece to be welded abuts against the plate and the side wall of the accommodating space. Then, the welding member 49 moves so that the welding end of the welding member 49 abuts against the workpiece to be welded. Finally, the welding member 49 begins ultrasonic welding.

[0044] This utility model discloses a welding device. Through the setting of a positioning component 25, the accommodating space can be used to position the workpiece to be welded. Positioning is completed as soon as the workpiece is placed in the accommodating space, resulting in fast positioning speed and improved positioning efficiency. The positioning component 25 is raised and lowered by a first lifting mechanism, thus preventing it from affecting the movement of the plate material. Simultaneously, the positioning component abuts against the plate material, preventing plate movement and improving positioning accuracy. Through the cooperation of the first feeding component 5, the conveying component 6, and the second feeding component 7, automatic feeding of the workpiece to be welded can be completed.
