[0002] Laser processing workstations are used for workpiece cutting or welding. A rotary table is located below the side wall of the workstation and is equipped with fixtures for holding the workpieces. The rotary table rotates to switch the fixtures between the outside and inside of the workstation. Workpieces are loaded and unloaded at a station outside the workstation, and then the rotary table rotates into the workstation for automated cutting or welding, repeating the cycle.

[0003] Existing laser processing workstations typically place their material racks on the outside of the workstation, with a certain distance between the materials and the clamps. This not only occupies floor space, hindering movement and posing safety hazards, but also makes loading and unloading workpieces more time-consuming, impacting processing efficiency. Therefore, there is an urgent need for a laser processing workstation with movable material racks to solve these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In the accompanying drawings, the dimensions and relative dimensions of certain parts may be enlarged for clarity.

They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, in the description of this utility model, the terms "first" and "second" are used merely for descriptive distinction and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] As per the instruction manual Figure 1 and 2 As shown, this utility model provides a laser processing workstation with a movable material rack, including a protective room 1, a laser processing equipment, and a rotary worktable 2. The laser processing equipment is located inside the protective room 1, and the protective room 1 has a window 11. The rotary worktable 2 is located at the window 11. It also includes a material rack 3, which is installed on the outside of the protective room 1 and above the rotary worktable 2. The material rack 3 includes a material box assembly and a material picking drive unit 33. The material picking drive unit 33 is connected to the protective room 1. One side of the material box assembly is hinged to the protective room 1, and the other side is hinged to the output end of the material picking drive unit 33, thereby having a material picking position close to the workstation's external work position and a standby position far from the workstation's external work position.

[0026] Specifically, the protective room 1 has a working space inside, referred to as the workstation body, for laser cutting or laser welding. The laser processing equipment is located inside the protective room 1. The laser processing equipment (not shown in the figure) is either laser welding equipment or laser cutting equipment, both of which are existing equipment and will not be described in detail here. The outside of the protective room 1 is referred to as the workstation body. The protective room 1 has a window 11, and a rotating worktable 2 is located at the window 11. The rotating worktable 2 can rotate under the action of a rotating drive unit, thus switching between the workstation body and the workstation body. The rotating worktable 2 is equipped with a fixture, and the workpiece to be processed is clamped in the fixture. The rotating worktable 2 rotates 180° each time. When the fixture is located at the workstation body position outside the workstation, the workpiece to be processed is clamped in the fixture. The rotating worktable 2 rotates 180°, and the fixture holding the workpiece to be processed moves into the workstation body for laser processing. After processing is completed, the rotating worktable 2 continues to rotate 180°, and the processed workpiece is removed from the fixture. The above operation is repeated for the processing of the next workpiece. Two sets of fixtures can be installed on the rotary worktable 2. The two sets of fixtures are set opposite to each other. One set of fixtures is inside the protective room 1 and the other set is outside the protective room 1. This ensures that the fixtures outside the protective room 1 can load and unload materials during workpiece processing, saving processing time and improving processing efficiency.

[0027] To achieve suitable distance and height between loading and unloading parts, the material box assembly is hinged to the side wall of the protective chamber 1. Under the action of the material handling drive unit 33, the material box assembly switches between a material handling position and a standby position. In the standby position, the material box assembly is horizontally positioned, higher than the rotary table 2, to prevent the rotary table 2 from colliding with the material rack 3 during rotation. In the material handling position, the material box assembly is tilted, and the connection node between the material box assembly and the material handling drive unit 33 is lower than the connection node between the material box assembly and the protective chamber, facilitating the removal of workpieces from the material box assembly. Specifically, the side of the material box assembly closest to the side wall of the protective chamber 1 is hinged to the side wall of the protective chamber 1, and the material handling drive unit 33 is hinged to the side wall of the protective chamber 1. The side of the material box assembly furthest from the side wall of the protective chamber 1 is hinged to the output end of the material handling drive unit 33, thus providing a material handling position close to the rotary table 2 and a standby position furthest from the rotary table 2. In the standby position, the material box assembly is positioned above the rotary table 2, avoiding interference with the rotation of the rotary table 2.

[0028] In an optimized implementation, to prevent the rotating worktable 2 from colliding with the material rack 3, the material picking drive unit 33 is equipped with a first limit switch 34, and / or the material box assembly is equipped with a second limit switch 35. Specifically, the material picking drive unit 33 is equipped with a first limit switch 34 to detect whether the material picking drive unit 33 has moved to the correct position; the second limit switch 35 is located on the side wall of the protective chamber 1 and corresponds to the material box assembly, and is used to detect whether the material box assembly has moved to the correct position. In this embodiment, both the first limit switch 34 and the second limit switch 35 are provided, providing dual signals and dual protection to avoid the risk of the rotating worktable colliding with the material rack.

[0029] Specifically, the first limit switch 34 is preferably a position sensor, and two such sensors are provided. The second limit switch 35 is preferably an end-position switch. The laser processing workstation is equipped with a PLC control unit. The first limit switch 34, the second limit switch 35, the material handling drive unit 33, and the rotary drive unit are all connected to the PLC control unit. The first limit switch 34 and the second limit switch 35 are respectively interlocked with the rotary drive unit of the rotary worktable 2.

[0030] In an optimized implementation, the material handling drive unit 33 is a cylinder. A start button 36 is provided on the side of the material box assembly away from the protective chamber 1. The start button 36 is electrically connected to the material handling drive unit 33 and can control the opening of the material handling drive unit 33.

[0031] As per the instruction manual Figure 3As shown, the specific control process is as follows: when the rotary table 2 is in position, the cylinder extends and the material box assembly moves to the lower limit state, that is, to the material picking position, which facilitates the picking of materials from the material box assembly and the operation of the fixture loading and unloading. After the fixture loading and unloading operation is completed, the start button 36 is pressed, the cylinder retracts, and the material box assembly begins to rise. When it reaches the upper limit state, that is, to the standby position, the first limit switch 34 and the second limit switch 35 signals will be triggered. After the PLC control unit binds these two signals, the rotary table 2 can rotate. The dual-layer signal logic avoids the rotary table from hitting the material rack.

[0032] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 2 As shown, the material box assembly includes a material box frame 31 and a plurality of material boxes 32. Each of the material boxes 32 is arranged side by side in the material box frame 31. Each of the material boxes 32 has a material dispensing port on its top. The side of the material box frame 31 closest to the side wall of the protective room 1 is hinged to the side wall of the protective room 1, and the side of the material box frame 31 furthest from the side wall of the protective room 1 is hinged to the output end of the material dispensing drive unit 33.

[0033] Specifically, the material box frame 31 is square, and multiple material boxes 32 are arranged side by side within the material box frame 31, with the height of the material boxes 32 exceeding the height of the material box frame 31. During use, the material boxes 32 can be numbered for easy and quick identification of the workpieces within them.

[0034] In an optimized implementation, a drive mounting base 37 is also provided on the side wall of the protective room 1. The material picking drive unit 33 is hinged to the drive mounting base 37, and the drive mounting base 37 is located above the connection node between the material box frame 31 and the protective room 1.

[0035] Specifically, see the instruction manual. Figure 3 As shown, the drive mounting base 37 is quadrilateral and has two vertical rods. The length of the vertical rods is parallel to the vertical direction. The two vertical rods are of different lengths and their bottoms are flush. A horizontal rod is connected between the bottoms of the two vertical rods, and a diagonal rod is connected between the tops of the two vertical rods. The longer vertical rod is fixedly connected to the side wall of the protective room. A hinge seat is provided at the bottom of the horizontal rod, and the material picking drive unit is connected to the hinge seat.

[0036] As one specific implementation, the material box frame 31 has ear-shaped connectors 311 at both ends near the protective chamber 1. Two ear-shaped supports 38 are provided on the side wall of the protective chamber 1, with each ear-shaped support 38 corresponding to one of the ear-shaped connectors 311. The ear-shaped connectors 311 are hinged to the ear-shaped supports 38, each ear-shaped support 38 having a pin hole. The ear-shaped connectors 311 have pins that fit with the pin holes. The material box frame 31 can rotate around the ear-shaped supports 38 under the drive of a cylinder. A second limit switch 35 is provided corresponding to one of the ear-shaped connectors 311 to monitor whether the ear-shaped connector 311 has moved to the correct position and determine whether the material box assembly has moved to the standby position. The material box frame 31 has fixed plates 312 at both ends away from the protective chamber 1. Each fixed plate 312 has a hinge plate with a hinge hole. The output end of the cylinder also has a hinge hole, and the two hinge holes are connected by a pin. The cylinder and the fixed plate can rotate around the pin. The protective enclosure 1 is equipped with two sets of drive mounting seats 37, which are set one-to-one with the fixed plates. Each drive mounting seat 37 is connected to the corresponding fixed plate through a cylinder. The two ends of the material box frame 31 are respectively provided with hinge nodes and material picking drive units 33, which can make the two ends of the material box frame 31 evenly stressed and rotate more smoothly.
