[0054] See also Figures 1 to 5 An embodiment of the utility model provides a loading device, which includes a base 100, a robot arm 200 and a magnetic suction mechanism 300. The robot arm 200 is movably connected to the base 100; the magnetic suction mechanism 300 is connected to one end of the robot arm 200, and the magnetic suction mechanism 300 is configured to have magnetism after power is turned on, and the magnetism disappears after power is turned off; wherein, the robot arm 200 drives the magnetic suction mechanism 300 to move vertically along the base 100 until it contacts the workpiece, the magnetic suction mechanism 300 is powered on to absorb the workpiece, the robot arm 200 drives the magnetic suction mechanism 300 and the workpiece to rise, and moves to the loading rack along the horizontal direction of the base 100, after the magnetic suction mechanism 300 is powered off, the workpiece is separated from the magnetic suction mechanism 300 and falls onto the loading rack.

[0055] The technical solution provides a loading device, in which the base 100 is used to connect and support the robot arm 200, and the robot arm 200 is used to drive the magnetic suction mechanism 300 to move along the horizontal and vertical directions of the base 100, so as to realize the transfer of the workpiece. By connecting the magnetic suction mechanism 300 to the robot arm 200, the workpiece is grasped and released by electromagnetic suction, so as to realize the loading of the workpiece. Through the above structural form, it is possible to realize fully automatic loading of the workpiece, solve the problem of long-term manual removal of bar-type workpieces from the material frame 800 and placing them on the automatic loading mechanism, and does not affect the transfer of the workpiece to the next workstation. The loading device provided in this embodiment does not need to touch the bar material from beginning to end, thereby reducing the labor intensity of personnel, saving labor costs, improving processing efficiency, and reducing the cost of bar material production.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the base 100 includes a frame 110 fixed to the bottom surface and a horizontal guide rail 120 arranged on the top of the frame 110, and the frame 110 is arranged beside the machine tool 900. The robot arm 200 includes a connecting seat 210, and the connecting seat 210 is guided and matched with the horizontal guide rail 120. The feeding device also includes a first motor 400 and a synchronous belt 500. The first motor 400 is arranged at the end of the horizontal guide rail 120; the synchronous belt 500 is fixedly connected to the connecting seat 210, and the synchronous belt 500 is drivingly connected to the output shaft of the first motor 400 to drive the connecting seat 210 to move along the extension direction of the horizontal guide rail 120.

[0057] By arranging the first motor 400 on the horizontal guide rail 120, the synchronous belt 500 is fixedly connected to the connecting seat 210, the synchronous belt 500 is driven to move by the first motor 400, and the connecting seat 210 is driven to move relative to the base 100 by the synchronous belt 500, so as to realize the horizontal movement of the robot arm 200 along the base 100. Specifically, a linear gear is fixedly connected to the output shaft of the first motor 400, the tooth groove on the synchronous belt 500 is meshed with the linear gear, the linear gear is driven to rotate by the first motor 400, and the synchronous belt 500 is driven to move by the linear gear. More specifically, two horizontal guide rails 120 are fixedly connected to the top of the frame 110, and the two horizontal guide rails 120 are arranged at intervals. Two spaced guide slides are arranged on the connecting seat 210, and the two guide slides are guided and matched with the two horizontal guide rails 120. In this way, the horizontal movement of the connecting seat 210 relative to the frame 110 is guided, and the stability of the horizontal movement of the connecting seat 210 is improved.

[0058] like Figure 2 , Figure 3 and Figure 4 As shown, further, the robot arm 200 also includes an arm body 220, on which a transmission rack 221 is arranged; the loading device also includes a second motor 600, which is connected to the connecting base 210, and a driving gear is fixedly connected to the output shaft of the second motor 600, and the driving gear is meshed with the transmission rack 221 to drive the arm body 220 to move in the vertical direction of the base 100.

[0059] It is understandable that the arm body 220 is used to connect with the magnetic attraction mechanism 300. The second motor 600 drives the driving gear to rotate, and the driving gear is engaged with the transmission rack 221 on the arm body 220 to realize the movement of the arm body 220 relative to the connecting seat 210, thereby realizing the vertical movement of the arm body 220 along the frame 110. Specifically, the arm body 220 is a long strip structure, and a mounting groove is provided on the arm body 220, and the extension direction of the mounting groove is consistent with the extension direction of the arm body 220, and the transmission rack 221 is fixedly connected to the side groove wall of the mounting groove.

[0060] For the magnetic attraction mechanism 300, in the embodiment of the present utility model, as Figures 3 to 5 As shown, the following structure is adopted:

[0061] In some of the embodiments, the magnetic attraction mechanism 300 includes a floating plate 310, a magnetic attraction component 320 and an elastic member 330. The floating plate 310 is fixedly connected to one end of the robotic arm 200. The magnetic attraction component 320 is movably connected to the floating plate 310, and the magnetic attraction component 320 is used to adsorb the workpiece. A plurality of elastic members 330 are disposed between the floating plate 310 and the magnetic attraction component 320, and the elastic members 330 are used to buffer the impact received by the magnetic attraction component 320.

[0062] By arranging a plurality of elastic members 330 spaced apart between the magnetic assembly 320 and the floating plate 310, the robot arm 200 drives the magnetic mechanism 300 to move downward. When the magnetic assembly 320 contacts the workpiece, the robot arm 200 continues to move downward. At this time, the elastic member 330 is conducive to absorbing the kinetic energy of the magnetic assembly 320, thereby preventing the magnetic assembly 320 from colliding with the floating plate 310, so as to protect the magnetic assembly 320 and thereby improve the life of the magnetic assembly 320. It is understandable that in this embodiment, the elastic member 330 is a spring or a rubber sleeve that has elasticity. The workpiece can be a bar or an object of other shapes that needs to be automatically loaded and unloaded.

[0063] like Figures 3 to 5 As shown, specifically, the magnetic attraction mechanism 300 further includes a linear bearing 340, two linear bearings 340 are respectively arranged at opposite ends of the floating plate 310; the housing of the linear bearing 340 is fixedly connected to one of the floating plate 310 and the magnetic attraction assembly 320; the guide shaft of the linear bearing 340 is fixedly connected to the other of the floating plate 310 and the magnetic attraction assembly 320; the guide shaft and the housing are in guiding cooperation. Such an arrangement can guide the movement of the magnetic attraction assembly 320 relative to the floating plate 310, so that the movement of the magnetic attraction assembly 320 relative to the floating plate 310 is more stable and reliable.

[0064] like Figures 3 to 5As shown, in some embodiments, the magnetic attraction assembly 320 includes a mounting seat 321 and two electromagnets 322, wherein the mounting seat 321 is movably connected to the floating plate 310; the two electromagnets 322 are spaced apart and connected to the mounting seat 321; wherein the distance between the two electromagnets 322 is adjustable. By movably connecting the mounting seat 321 to the floating plate 310, the mounting seat 321 can move up and down relative to the floating plate 310. By setting the two electromagnets 322 in a form in which the distance between the two is adjustable, the magnetic attraction assembly 320 can be applied to workpieces of different sizes, thereby improving the application range of the feeding device.

[0065] Specifically, a limited slot is constructed on the mounting seat 321; the electromagnet 322 includes a base 3221, and a limited protrusion is constructed on the base 3221. The limited protrusion is clamped in the limited slot, and the position of the limited protrusion in the limited slot is adjustable. Specifically, the structure of the limited slot is a dovetail slot, and the shape of the limited protrusion is adapted to the dovetail slot. By setting the limited protrusion in the limited slot in an adjustable position, the relative position of the electromagnet 322 on the mounting seat 321 can be adjusted.

[0066] like Figures 3 to 5 As shown, further, the mounting seat 321 includes a limit adjustment block 3211 and a clamping block 3212, and the limit adjustment block 3211 is provided with a first limit groove; the limit adjustment block 3211 is also provided with a plurality of threaded holes arranged at intervals; the clamping block 3212 is provided with a second limit groove, and the clamping block 3212 is provided with a plurality of mounting holes arranged at intervals, and the mounting holes and the threaded holes correspond one to one; the first limit groove and the second limit groove jointly define a limit slide groove, and the fastener passes through the mounting hole and is threadedly connected with the threaded hole to clamp the limit protrusion between the limit adjustment block 3211 and the clamping block 3212.

[0067] The mounting seat 321 is configured to be fixed by the limit adjustment block 3211 and the clamping block 3212 through fasteners, and the limit slide groove is configured to be formed by the first limit groove on the limit adjustment block 3211 and the second limit groove on the clamping block 3212. When the limit adjustment block 3211 and the tightening block are fixed by fasteners, the clamping block 3212 and the limit adjustment block 3211 can jointly apply a force to the limit protrusion on the base 3221, so that the base 3221 after the position adjustment can be fixed to the mounting seat 321, thereby improving the reliability of the operation of the magnetic suction assembly 320 during loading.

[0068] like Figures 3 to 5As shown, in some embodiments, the magnetic attraction component 320 also includes a detection member 350, and the detection member 350 is connected to the floating plate 310. When the detection member 350 detects that the magnetic attraction component 320 moves to a preset position relative to the floating plate 310, the magnetic attraction component 320 is energized. Specifically, the detection member 350 is a proximity switch, and two proximity switches are arranged on the floating plate 310. The magnetic attraction component 320 moves downward under the action of the robot 200. When the electromagnet 322 touches the bar material, the robot 200 continues to move downward. When the spring between the limit adjustment block 3211 and the floating plate 310 is compressed, when the proximity switch on the floating plate 310 contacts the limit adjustment block 3211, the robot 200 stops moving downward. After the electromagnet 322 is energized to absorb the bar material, the robot 200 starts to move upward to lift the bar material. When the robot arm 200 rises to a certain position, the robot arm 200 moves in the horizontal direction under the drive of the first motor 400. When it moves above the loading rack of the processing equipment, the power is cut off to demagnetize the electromagnet 322, so that the sucked rods fall into the loading rack.

[0069] like Figure 1 and Figure 2 As shown, the utility model also provides a feeding system, which includes the feeding device as above, and the base 100 is constructed with a material frame 800 bin; the feeding system includes a limiting component, and the limiting component includes: two limiting plates 700 arranged at intervals, the limiting plate 700 includes a first plate body 710 and a second plate body 720, the first plate body 710 and the second plate body 720 are arranged at an angle, the first plate body 710 and the second plate body 720 are enclosed and define a limiting groove, and the limiting grooves on the two limiting plates 700 are arranged oppositely; a tension spring, the two ends of which are respectively connected to the limiting plate 700 and the base 100; wherein the limiting plate 700 is rotatably connected to the bottom of the base 100 and is located in the material frame 800 bin, when the material frame 800 falls, the material frame 800 presses on the first plate body 710 to drive the limiting plate 700 to rotate, and a limiting space for limiting the material frame 800 is defined between the two second plates 720.

[0070] Specifically, the frame 110 is provided with the above-mentioned material frame 800 bin, and the material frame 800 bin is used to accommodate the material bin. By setting the above-mentioned limiting plate 700 in the material frame 800 bin, the falling position of the material frame 800 is limited, so that the falling position of the material frame 800 is at the same position each time, thereby improving the reliability of the loading device when loading materials.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
