Description

Technical Field

[0001] This application relates to the technical field of laser welding, and in particular to a welding apparatus for decorative aluminum frames. Background Technology

[0002] With the rapid development of the modern construction and decoration industry, people's requirements for the aesthetics, quality, and personalization of building exteriors and interior decorations are increasing. Decorative aluminum frames, due to their numerous advantages such as light weight, high strength, corrosion resistance, ease of processing and forming, and excellent decorative properties, have been widely used in many fields, including building curtain walls, doors and windows, interior decorative partitions, and furniture frames.

[0003] Before the aluminum frame is used, the profiles need to be processed, such as welding. Most existing welding is done by laser welding machines. The profiles are clamped by fixtures, and the laser welding head melts the area to be welded. The molten metals fuse together to achieve a connection. The welding process is monitored by a CCD camera system to ensure the welding is stable.

[0004] Existing laser welding equipment generates welding fumes during the welding process due to the melting effect on the metal. Inhaling these fumes can cause irreversible damage to the human body. Currently, existing laser welding equipment typically does not treat these fumes. For example, the CHD-1000W / 1500W / 2000W-CW laser welding machine used by our company does not have a welding fume treatment device. Therefore, to ensure the health and safety of workers, a welding fume treatment device is added to this type of laser welding machine. This application provides a decorative aluminum frame welding device. Utility Model Content

[0005] To address the issue that existing laser welding machines are not equipped with fume treatment, this application provides a decorative aluminum frame welding device.

[0006] This application provides a decorative aluminum frame welding device, including a body. Above the body are three electric modules (Mod I, Mod II, and Mod III) for X, Y, and Z axis driving. A support arm is connected to Mod III via a transmission. A laser welding head is mounted at the front end of the support arm, and a matching CCD camera system is mounted on one side of the laser welding head. An absorption ring is located on the outer side of the bottom of the laser welding head, with its opening facing the welding position of the laser welding head. A support structure is located on one side of the absorption ring. The support structure includes a drive frame, and the drive frame is threadedly connected to a threaded rod in Mod III. The support structure also includes a purification mechanism connected to the absorption ring.

[0007] By setting an absorption ring on the outside of the laser welding head, the position of the absorption ring is independently supported by the bracket structure, which reduces the impact on the position of the laser welding head and does not affect the welding accuracy. At the same time, the bracket structure installed on the electric module three can also ensure that the position of the absorption ring and the laser welding head is synchronized. With the help of the purification mechanism, the welding fume can be effectively purified.

[0008] Preferably, the support structure further includes an intermediate plate attached to one side of the laser welding head, the absorption ring is fixed on the intermediate plate, the intermediate plate and the drive frame are fixedly connected by an air pipe, and the air pipe is connected to the input end of the purification mechanism.

[0009] Preferably, the absorber ring has an air groove inside, the air groove has a two-section structure, the width of its opening is smaller than the width of the inside, and the air groove and the air pipe are connected.

[0010] Preferably, the absorption ring and the laser welding head are arranged coaxially, and the height of the absorption ring is greater than the height of the end of the laser welding head.

[0011] Preferably, a steering motor is bolted to the intermediate plate, and a protective lens is fixedly connected to the output end of the steering motor.

[0012] Preferably, the plane on which the protective lens is located is below the CCD camera system.

[0013] Preferably, the machine body is provided with a clamping block to clamp the aluminum material.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By setting an absorption ring on the outside of the laser welding head, the position of the absorption ring is independently supported by the bracket structure, which reduces the impact on the position of the laser welding head and does not affect the welding accuracy. At the same time, the bracket structure installed on the electric module three can also ensure that the position of the absorption ring and the laser welding head is synchronized. With the help of the purification mechanism, the welding fume can be effectively purified.

[0016] By installing a steering motor on the middle plate to drive the position of the protective lens, the lens of the CCD camera system can be protected, thereby improving the durability and safety of the device. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0023] Example 1:

[0024] A decorative aluminum frame welding device, as shown in the reference Figure 1 - Figure 4 The machine body 1 is equipped with three electric modules: 2, 3, and 4, which drive the X, Y, and Z axes. A support arm 5 is connected to the support arm 4, and a laser welding head 6 is mounted at the front end of the support arm 5. A matching CCD camera system 7 is located on one side of the laser welding head 6. An absorption ring 9 is located on the outer side of the bottom of the laser welding head 6, with its opening facing the welding position of the laser welding head 6. A support structure is located on one side of the absorption ring 9, including a drive frame 14. The drive frame 14 and the threaded rod in the electric module 4 are threadedly connected. When the electric module 4 rotates, it drives the drive frame 4 and the support arm 5 to move up and down synchronously, ensuring structural uniformity while minimizing welding fume emissions. The modified structure does not increase the weight of the original laser welding head 6, thus effectively preventing the welding fume purification structure from affecting the precision of the laser welding head 6. The support structure also includes a purification mechanism 15 connected to the absorption ring 9. The purification mechanism 15 is equipped with a filter structure and an air pump. The air pump input end is connected to the air pipe 13. When the air pump is working, the external airflow passes through the air pipe 13 and finally enters the purification mechanism 15. In the purification mechanism 15, it passes through the filter structure and is purified and adsorbed by the filter structure. Then, it is output from the air pump output end and discharged to the outside from the top of the purification mechanism 15. The purification mechanism 15 adopts a detachable structure, and it can be cleaned and the internal filter structure replaced regularly to ensure the purification effect of welding fumes.

[0025] The support structure also includes an intermediate plate 10 attached to one side of the laser welding head 6. The absorption ring 9 is fixed on the intermediate plate 10. The intermediate plate 10 and the drive frame 14 are fixedly connected by an air pipe 13. The air pipe 13 is connected to the input end of the purification mechanism 15. The air pipe 13 is made of rigid material and is used to fix the position of the absorption ring 9 in front of the drive frame 14. It also provides a channel for welding fumes, ensuring that the welding fumes absorbed by the absorption ring 9 enter the purification mechanism 15. The absorption ring 9 has an air groove 91 inside. The air groove 91 has a two-section structure. The width of its opening is smaller than the width of its interior. The air groove 91 and the air pipe 13 are connected. The purpose of the two-section air groove 91 structure is that, due to the smaller width of the opening, the airflow has a higher velocity when passing through the opening. Therefore, under the same power conditions, it has a better absorption effect on welding fumes than a larger opening. The welding fumes after passing through the opening of the air groove 91 enter the interior of the air groove 91 and finally enter the purification mechanism 15 through the air pipe 13. The absorption ring 9 and the laser welding head 6 are arranged coaxially, and the height of the absorption ring 9 is greater than the height of the end of the laser welding head 6. The coaxial arrangement of the absorption ring 9 and the laser welding head 6 ensures that they do not come into contact with each other, while the height limitation of the absorption ring 9 ensures that the absorption ring 9 will not have an adverse effect on the welding position during the welding process.

[0026] A steering motor 12 is bolted to the intermediate plate 10, and a protective lens 11 is fixedly connected to the output end of the steering motor 12. The plane of the protective lens 11 is located below the CCD camera system 7. The rotation range of the steering motor 12 is 0-180°. At the 0° position, the protective lens 11 blocks the CCD camera system 7 from below, thereby protecting the lens of the CCD camera system 7. The protective lens can be an absorptive filter, a reflective protective lens 11, or a photochromic protective lens, etc., which can effectively filter the arc light generated during welding to avoid irreversible damage to the lens of the CCD camera. When the CCD camera is working, the steering motor can rotate to a 90° or 180° position for standby.
