Description

Technical Field

[0001] The utility model relates to the technical field of material taking and feeding of laser cutting machines, in particular to a flipping type laser cutting material taking device. Background Art

[0002] After a workpiece is processed by a laser cutting machine, a material taking device is usually used to directly grab the workpiece. During the process of grabbing and feeding the workpiece, it is usually completed by one device. Therefore, the action stroke of the material taking device is large, and the time length for performing a single grab and feeding is also large. Therefore, currently, a material taking robotic arm is usually set to first remove the workpiece above the laser cutting machine, and then place it on a temporary storage platform, and then the material taking device grabs and feeds it. Although this solution can improve the feeding rate, however, since the robotic arm needs to position the workpiece on the laser cutting machine during the process of taking and placing the material, and needs to re-position the temporary storage platform during the process of placing the material, thus, in the actual use process, the material taking efficiency is also low, and a detection and positioning device needs to be set, resulting in a high production cost.

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, the descriptions such as "first" and "second" set in the embodiments of the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

[0036] The embodiment of the present utility model provides a flip-type laser cutting and material taking device. As Figures 1-4 shown, it includes a machine table 100 and a laser cutting machine 101. It is characterized in that a flipping device 200 and a material taking robot 300 are arranged on the machine table 100. After the flipping device 200 flips towards the laser cutting machine 101, it is used to suck the workpiece processed by laser cutting, and then after flipping in the opposite direction, the workpiece faces upward, which is convenient for the material taking robot 300 to suck the workpiece located on the flipping device 200. After the workpiece is transported by the flipping device 200, the workpiece can be temporarily stored in the flipping device 200 in advance, which is more convenient for the material taking robot 300 to load materials. The material taking method of the flipping device 200 is convenient and fast, and can make the flipping plate 220 dock with the working position of the laser cutting machine 101 during flipping, saving the step of repositioning and alignment and improving the loading efficiency.

[0037] As Figures 2-4 shown, the flipping device 200 is arranged corresponding to the laser cutting machine 101 for sucking the workpiece processed by the laser cutting machine 101. The flipping device 200 includes a frame 210, a flipping plate 220 rotatably connected to one end of the frame 210, and a first driving device 230 for driving the flipping plate 220 to flip along the pivot. An adsorption hole 221 communicated with an external air source is arranged on one side surface of the flipping plate 220; a suction head 310 for sucking the workpiece is arranged at the end of the material taking robot 300 for sucking the workpiece transported by the flipping device 200.

[0038] In this embodiment, the first driving device 230 can be a motor. The motor is connected to the rotating shaft 224 through a transmission device, so as to drive the turning plate 220 to turn. In other embodiments, the first driving device 230 can also be a rotary cylinder, and its output shaft is connected to the rotating shaft 224 through a transmission device, so as to drive the turning plate 220 to realize the turning action.

[0039] After the laser cutting machine 101 processes the workpiece, the turning plate 220 of the turning device 200 turns towards the direction of the laser cutting machine 101 under the drive of the first driving device 230, so that the turning plate 220 corresponds to the working position on the laser cutting machine 101. They can correspond precisely to each other, and it is convenient and fast to suck the workpiece processed by the laser cutting machine 101. It can be imagined that the turning plate 220 turns along the pivot under the drive of the first driving device 230, and the turning trajectory of the turning plate 220 is fixed. At the same time, the position of the laser cutting machine 101 and the position of the working position thereon are also fixed. Therefore, after the turning plate 220 is turned, it can be quickly aligned with the work of the laser cutting machine 101, avoiding the action of aligning again. It can quickly suck the workpiece processed by the laser cutting machine 101 and temporarily store it thereon, which is convenient for the picking robot 300 to suck and load. Thus, the positioning actions and processes can be reduced, the loading rate can be improved, and the production cost of the equipment can be reduced.

[0040] In this embodiment, as Figures 2-4 shown, the turning plate 220 includes a plate main body 222 and a connecting arm 223. The adsorption holes 221 are arranged on one side surface of the plate main body 222 and are arranged in a matrix. A pipeline for communicating the adsorption holes 221 with an external air source is arranged on the other side surface of the plate main body 222; one end of the connecting arm 223 is formed on the plate main body 222, and the other end extends towards the outside and is fixedly provided with a rotating shaft 224. The rotating shaft 224 is fixedly connected to the frame 210 and is in transmission connection with the first driving device 230.

[0041] By providing the connecting arm 223 on the plate main body 222, the turning radius of the plate main body 222 can be increased, and the distance between the turning device 200 and the laser cutting machine 101 can be increased, avoiding mutual interference during the working process.

[0042] Similarly, as Figures 2-4 shown, the frame 210 includes a support portion 211. The support portion 211 is fixedly installed on the machine table 100, and its upper end is formed with an extension portion 212 extending towards the direction of the laser cutting machine 101. The rotating shaft 224 is rotatably connected to the end of the extension portion 212.

[0043] The turnover plate 220 is rotatably connected to the extension 212 of the frame 210, which can prevent the length of the turnover plate 220 from being too long and affecting the stability of the turnover of the turnover plate 220 driven by the first driving device 230. At the same time, the distance between the turnover device 200 and the laser cutting machine 101 is ensured, and the safety performance of the work is guaranteed.

[0044] As Figure 4 shown, a support block 213 is formed on the side wall of the support portion 211. The support block 213 corresponds to the connecting arm 223 and is used to support the connecting arm 223 after the turnover plate 220 is turned over along the rotating shaft 224.

[0045] After the turnover plate 220 sucks the workpiece of the laser cutting machine 101 and turns over in the opposite direction, the support arm abuts against the support block 213 and is placed on the support block 213, and is supported by the support block 213, so as to ensure that the turnover plate 220 has strong stability and will not shake, which is convenient for the robot 300 to suck the workpiece located on the turnover plate 220.

[0046] When the first driving device 230 drives the turnover plate 220 to turn over along the rotating shaft 224, in order to prevent the turnover plate 220 from coming into hard contact with the working position of the laser cutting machine 101 or the support block 213 due to the inertia of turning over after reaching the final position, damaging the relevant components or causing inertial impact to the transmission mechanism, or the turnover plate 220 vibrating after the hard contact, therefore, a buffer structure is also provided on the turnover plate 220. As Figures 3-4 shown, the buffer structure includes a resisting member 214 and a buffer 216. One end of the resisting member 214 is fixedly connected to the rotating shaft 224, and the other end extends radially along the rotating shaft 224 to form a resisting end 215. The axis direction of the resisting member 214 is perpendicular to the axis direction of the turnover plate 220, so that when the turnover plate 220 is in a horizontal state, the resisting member 214 is in a vertical state; the buffer 216 includes two that are fixedly installed side by side on the frame 210 in the vertical direction, and the abutting end of the buffer 216 faces the direction of the resisting member 214. The two buffers 216 are respectively located on the upper and lower sides of the axis of the rotating shaft 224 and correspond to the abutting ends of the resisting member 214 facing upward or downward.

[0047] When the first driving device 230 flips the flip plate 220, when the flip plate 220 flips toward the direction of the laser cutting machine 101 and corresponds to the working position on the laser cutting machine 101, the flip plate 220 is in a horizontal state, the stopper 214 is in a vertical state, and the stopper end 215 faces downward. During the flipping process, when the flip plate 220 is about to reach a horizontal state (that is, when it is about to be aligned with the working position of the laser cutting machine 101), the stopper end 215 contacts the buffer 216 in advance, and the buffer 216 absorbs the rotational force of the flip plate 220, so that the flip plate 220 can slowly flip to the working position of the laser cutting machine 101, thereby avoiding hard contact, and making the flip plate 220 more stable and accurate when docking with the laser cutting machine 101.

[0048] In this embodiment, the suction head 310 driven by the robot arm 300 has the following structure: Figures 5-7 As shown, the suction head 310 includes a frame 311, a second driving device 312 and a suction cup assembly 313. The frame 311 is fixedly mounted at the end of the second robot arm 300, and the frame 311 includes at least one vertically arranged side plate 318; the second driving device 312 includes at least two arranged side by side, which are fixed on the side plate 318; the suction cup assembly 313 is transmission-connected to the first driving device 230, and is driven by the first driving device 230 to reciprocate in the vertical direction.

[0049] In this embodiment, two side panels 318 facing each other are arranged on the frame 311, and two second driving devices 312 arranged side by side and a suction cup assembly 313 driven by the second driving devices 312 are installed on each side panel 318. The suction cup assembly 313 moves downward under the drive of the second driving device 312 to flip the workpiece on the flip plate 220.

[0050] In this embodiment, the suction cup assembly 313 includes a fixed block 314, a rod 315 and an elastic member 317. The fixed block 314 is transmission-connected to the second driving device 312, and is provided with a through hole 319 along the vertical direction; the rod 315 is slidably connected in the hole along the vertical direction, and an air duct 3151 is provided inside the rod 315 for communication with an external air source, a suction nozzle 316 is fixedly installed on the lower end of the rod 315, and the suction nozzle 316 is connected to the air duct 3151; the elastic member 317 is mounted on the rod 315 to provide an elastic force downward to the rod 315.

[0051] During the process of adsorbing the workpiece on the turning plate 220, after the suction nozzle 316 at the lower end of the rod 315 comes into contact with the workpiece, through the buffering of the elastic member 317, the mutual contact force between the suction nozzle 316 and the workpiece is small, avoiding damage to the workpiece or the suction nozzle 316 and ensuring the feeding performance.

[0052] For those skilled in the art, various corresponding changes and deformations can be obtained according to the structure and principle disclosed by the present utility model, and all such changes and deformations fall within the protection scope of the present utility model.
