Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment, specifically to an adsorption-type strip switching and feeding mechanism for laser welding. Background Technology

[0002] Laser welding is one of the commonly used welding methods. In the laser welding process, for laser welding of sheet-like workpieces, the assembled sheet-like workpieces need to be positioned and clamped before being sent to the laser welding machine for welding.

[0003] Traditional positioning and clamping mechanisms mostly use fixed clamps to position and hold sheet metal workpieces. Mechanical clamping can easily cause deformation of thin sheets, and after each sheet is processed, the machine needs to be stopped intermittently for loading and unloading. Therefore, there is a need for an adsorption-type sheet metal switching and unloading mechanism for laser welding to meet the requirements of efficient and high-quality laser welding. Utility Model Content

[0004] The purpose of this invention is to provide an adsorption-type strip switching and unloading mechanism for laser welding, which can automatically adsorb, fix and unload strips, avoid product deformation caused by mechanical clamping, and achieve uninterrupted loading, unloading and laser processing, thereby improving production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding adsorption-type strip switching and feeding mechanism, comprising a machine base, a rotating mechanism fixedly connected to the machine base, a central positioning column fixedly connected to the rotating platform of the rotating mechanism, a plurality of air extraction holes on the central positioning column, a strip loading assembly detachably connected to the central positioning column, the strip loading assembly comprising a mounting sleeve and a screw, a plurality of mounting surfaces on the mounting sleeve, a strip positioning plate detachably connected to each mounting surface, an adsorption hole on each strip positioning plate, an airflow channel on the mounting sleeve, and the air extraction holes and adsorption holes communicating with the airflow channel.

[0006] Furthermore, the rotating mechanism includes a servo motor and a transmission assembly, the output end of the servo motor is fixedly connected to the input end of the transmission assembly, and the output end of the transmission assembly is fixedly connected to the central positioning column.

[0007] Furthermore, the multiple slat positioning carriers are arranged in a circular array on the mounting sleeve, and each slat positioning carrier is provided with a positioning protrusion. The slat positioning carrier is detachably connected to the mounting sleeve.

[0008] Furthermore, the central positioning post is provided with an angle positioning block, and the mounting sleeve is provided with an alignment groove corresponding to the angle positioning block. The mounting sleeve is fixedly connected to the central positioning post by screws.

[0009] Furthermore, a discharge channel is fixedly connected to the side of the rotating mechanism on the machine platform. The discharge channel is inclined on the machine platform and located below the mounting sleeve.

[0010] Furthermore, each of the slat positioning carriers has multiple adsorption holes, and these multiple adsorption holes are evenly distributed on the slat positioning carriers.

[0011] The beneficial effects of this utility model are as follows: by using the rotating mechanism, the central positioning column and the slat positioning carrier plate in combination, the slats can be automatically adsorbed, fixed and unloaded, avoiding product deformation caused by mechanical clamping, while realizing uninterrupted loading and unloading and laser processing, thus improving production efficiency.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0018] Example:

[0019] refer to Figures 1-4The laser welding adsorption-type strip switching and feeding mechanism shown includes a machine base 1, a rotating mechanism 2 fixedly connected to the machine base 1, a central positioning column 3 fixedly connected to the rotating platform of the rotating mechanism 2, a plurality of air extraction holes 301 provided on the central positioning column 3, and a strip loading assembly detachably connected to the central positioning column 3. The strip loading assembly includes a mounting sleeve 401 and a screw 402. The mounting sleeve 401 is provided with a plurality of mounting surfaces, and a strip positioning carrier plate 5 is detachably connected to each mounting surface. Each strip positioning carrier plate 5 is provided with an adsorption hole 501. The mounting sleeve 401 is provided with an airflow channel. The air extraction holes 301 and the adsorption holes 501 are both connected to the airflow channel. By drawing a vacuum through the air extraction holes 301, the strip workpiece can be adsorbed onto the strip positioning carrier plate 5 through the adsorption holes 501.

[0020] The rotating mechanism 2 includes a servo motor 201 and a transmission assembly 202. The servo motor 201 and transmission assembly 202 drive the central positioning post 3 to rotate, thereby achieving the rotational switching action of the slat loading assembly. Multiple slat positioning plates 5 are arranged in a circular array on the mounting sleeve 401. Positioning protrusions 502 on the slat positioning plates 5 are used for positioning and placing the slat workpieces. The slat positioning plates 5 are detachably connected to the mounting sleeve 401, allowing for replacement of slats of different specifications and accommodating the positioning and placement of slats of different sizes. An angle positioning block 6 fixed to the central positioning post 3 is used to position the mounting sleeve 401 at a specified angle. The mounting sleeve 401 has an alignment groove corresponding to the angle positioning block 6. The mounting sleeve 401 is fixedly connected to the central positioning post 3 by screws. The entire mounting sleeve 401 can be disassembled and replaced on the central positioning post 3.

[0021] A discharge channel 7 is fixedly connected to the side of the rotating mechanism 2 on the machine base 1. The discharge channel 7 receives the slat products that have been guided and laser-welded. The discharge channel 7 is set at an angle on the machine base 1 and is located below the mounting sleeve 401.

[0022] Each slat positioning carrier plate 5 has multiple adsorption holes 501, and the multiple adsorption holes 501 are evenly distributed on the slat positioning carrier plate 5, which can further improve the adsorption effect of the adsorption holes 501 on the slat workpiece.

[0023] The working principle of this utility model is as follows: The strip is fed from the left or right side of the mounting sleeve 401. The pre-assembled strip workpiece is placed on the strip positioning carrier plate 5 along the positioning protrusion 502. The strip is then adsorbed and fixed through the adsorption hole 501. Next, the mounting sleeve 401 is driven to rotate by the rotating mechanism 2, causing the strip to be processed to be sequentially rotated to the laser welding station (the upper end face of the mounting sleeve 401 is the laser processing station). An external laser welder is then used to weld the parts of the strip workpiece that need to be welded. After the welding process is completed, the rotating mechanism 2 rotates the processed strip to the bottom of the mounting sleeve 401. At this time, the air extraction hole 301 corresponding to the strip positioning carrier 5 stops vacuuming (at this time, other strip positioning carriers 5 are normally adsorbed). After the strip positioning carrier 5 rotates again from the unloading station, it is reloaded. After each strip positioning carrier 5 on the mounting sleeve 401 has undergone laser processing, unloading and loading, the rotating mechanism 2 drives the mounting sleeve 401 to rotate back to the initial position and repeat the above processing.

[0024] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
