Description

Technical Field

[0001] The utility model discloses a welding device for a side guard plate of an automobile, belongs to the technical field of welding robots, and specifically relates to a welding device capable of quickly replacing a welding gun. Background Art

[0002] Ultrasonic welding equipment is mainly used to weld, join or fix materials, and its functions include but are not limited to the following aspects:

[0003] Welding and joining: The most common use is to connect two or more workpieces together in an instant through thermoforming materials. This connection can be permanent and is usually made between materials such as plastics, metals, electronic components, etc.

[0004] Sealing: Ultrasonic welding can achieve good sealing effect while joining materials, and is suitable for the manufacture of products with high requirements such as waterproofness and airtightness, such as electronic equipment, medical equipment, etc.

[0005] Fast and efficient: Compared with traditional welding or bonding methods, ultrasonic welding can complete high-strength welding in a shorter time, improving production efficiency and product quality.

[0006] No additional materials are required: Ultrasonic welding usually does not require additional adhesives or additives. The material is welded only by the heat generated by high-frequency vibration, avoiding the problems that may be caused by material contamination or additives.

[0007] Easy operation and automation: The equipment operation is relatively simple, suitable for application on automated production lines, and can achieve efficient production through program control.

[0045] Working principle: When this utility model works, it is divided into the following processes:

[0046] Welding process:

[0047] The welding robot 4 performs the welding work by adjusting the position and angle of the six-axis robot arm 8 and cooperating with the welding gun 11. The welding image is collected and uploaded by the industrial camera 9.

[0048] Quick tool change process:

[0049] The welding robot 4 cooperates with the welding gun quick-change tool platform mechanism 5 to execute the operation. The welding robot 4 moves to the welding gun quick-change tool platform mechanism 5, and at the same time, the first cylinder 14 works to drive the locking plate 16 to move out. At this time, the welding gun 11 is in an unlocked state. At this time, the telescopic cylinder 10 works to place the welding gun 11 of the welding robot 4 in the tool groove on the tool plate 13, and replaces the new welding gun 11. After the replacement is completed, the work continues. At the same time, the first cylinder 14 works to drive the locking plate 16 to cooperate with the guide plate 15 to lock the welding gun 11;

[0050] Tooling rotation process:

[0051] When the tooling needs to be rotated, the first motor 30 in the tooling rotating mechanism 3 works, driving the rotating frame 31 to rotate through the turntable 29, thereby driving the mold mounting plate 32 and the tooling table 35 to rotate; at the same time, the detector 36 detects whether the rotation position is correct. During the rotation, the third cylinder 22 is in a retracted state;

[0052] Tool height adjustment process:

[0053] When the height needs to be adjusted, the second cylinder 21 is used to drive the linkage plate 19 to move through the first guide rail 17 and the first slider 18, thereby driving the bevel plate 20 to contact the pulley 27, and following the slope of the bevel plate 20, thereby driving the lifting rod 26 to move up and down through the second slider 25 and the second guide rail 28, thereby achieving the height adjustment of the tooling;

[0054] In addition, the tooling height adjustment drives the template lifting mechanism 33 to work through the push rod 23 to achieve the fixation of the mold mounting plate 32.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
