AI Technical Summary
When existing automatic welding equipment is used to weld doors and windows with larger structures, the mechanical cantilever has low stability to move on the Z axis, resulting in easy collision of the welding gun head and damage to the welding gun head and materials.
A welding device with an anti-collision structure is designed, including a control module, a welding gun and an anti-collision structure. The anti-collision structure consists of a connector, a slipperable striker and an emergency stop sensor. The second end of the striker protrudes the first preset length of the tip of the welding gun. The emergency stop sensor sends an emergency stop signal on the extension line of the striker. To prevent welding gun collision.
By introducing an anti-collision structure into the welding device, an emergency stop signal can be issued before the welding gun hits the workpiece, and the welding gun stops moving, thereby avoiding damage to the welding gun, and improving the stability and safety of the welding process.

Description
Technical Field
[0001] The utility model relates to the field of welding devices, in particular to a welding device with an anti-collision structure. Background Art
[0002] At present, there are automatic welding equipment in the field of welding devices that can automatically locate the welding position and weld the welded parts. In the existing automatic welding equipment, the welding gun head is usually installed on the machine head, and the machine head is driven by a mechanical cantilever so that it can move freely on the X-axis, Y-axis and Z-axis. However, when welding products with large structures such as doors and windows, the machine head of the automatic welding equipment is heavy, resulting in low stability of the mechanical cantilever moving on the Z-axis; at the same time, when welding different materials, different welding material heights must be calculated. Once the welding material height is not calculated or calculated incorrectly, the welding gun head will move too much, which will cause the welding gun head to collide with the material or workbench, damaging the welding gun head and the material.
[0003] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention
[0004] In order to improve or solve the technical problem of easy collision of welding gun heads in the prior art, the utility model provides a welding device with an anti-collision structure. The welding device includes: a control module for controlling the action of the welding equipment; a welding gun connected to the control module; an anti-collision structure, including a connecting piece fixedly connected to the welding gun, and a striker arranged side by side with the welding gun and slidably arranged in the connecting piece; the striker slides along the length direction of the welding gun and has a first end and a second end opposite to each other, the second end protruding a first preset length of the gun head of the welding gun; an emergency stop sensor is arranged on the connecting piece, the emergency stop sensor is arranged on the extension line of the striker and is spaced from the first end by a second preset length, the second preset length is less than the first preset length, and the emergency stop sensor is configured to send an emergency stop signal to the control module when hit by the striker.
[0005] In the welding device with anti-collision structure of the utility model, a control module, a welding gun and an anti-collision structure are included. Among them, the control module is used to control the operation of the welding equipment, such as the movement and working state of the welding gun. The welding gun is used to emit a high-energy laser beam as a heat source to weld the workpiece. The anti-collision structure includes a striker and a connecting piece, and the second end of the striker protrudes from the gun head of the welding gun by a first preset distance, so the striker will hit the workpiece before the welding gun; at the same time, an emergency stop sensor is arranged in the connecting piece, and the emergency stop sensor is arranged on the extension line of the striker and is spaced from the first end by a second preset length, and the second preset length is less than the first preset length, so that the striker hits the emergency stop sensor, and when the control module stops in an emergency, the welding gun still does not collide with the workpiece, thereby protecting the welding gun. Through the above-mentioned setting, the welding device with anti-collision structure of the utility model can send an emergency stop signal before the welding gun hits the workpiece, and control the welding gun to stop moving, thereby avoiding damage to the welding gun.
