Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly to a feeding device. Background Art

[0002] In industrial production, for the production of workpieces with relatively large weights, it is difficult to achieve feeding manually, and feeding equipment needs to be used to implement the feeding process of workpieces. Existing feeding equipment usually uses an adsorption device to adsorb and connect with a blank, so as to implement the feeding process of workpieces. However, when connecting with a workpiece by adsorption, the requirement for the placement posture of the blank is very high, and it needs to be completely attached to the adsorption device. Taking laser-cut parts as an example, they are usually formed by using a laser cutting machine to cut on a large-sized plate. When the plate is initially supplied, it is usually placed in bundles. Before preparing for feeding, a hoisting device such as a crane can be used to place the bundled plates into a material frame. After the plates are unbundled, they are usually not neatly arranged, and there may be situations of skewing and toppling. For skewed and toppled plates, during the process of the adsorption device adsorbing and connecting with the plates, if it cannot be completely attached to the plates, there may be situations where the adsorption connection cannot be achieved or the connection is not firm, thereby affecting the feeding speed and production safety. Therefore, there is an urgent need for a feeding device that can improve the stability and firmness of the adsorption connection with workpieces and enhance the feeding speed and production safety. Summary of the Invention

[0003] In view of this, the main purpose of the present invention is to provide a feeding device that can improve the stability and firmness of the adsorption connection with workpieces and enhance the feeding speed and production safety.

[0004] The present application provides a feeding device, including a displacement device and a suction device. The displacement device has a mounting frame, and the displacement device can drive the mounting frame to move. A plurality of suction devices are provided and are arranged on the mounting frame. The suction device includes: a connecting rod, one end of the connecting rod is arranged on the mounting frame and is slidably connected to the mounting frame; a first elastic member, one end of the first elastic member is connected to the mounting frame, and the other end is connected to the connecting rod; a suction head, the suction head is arranged at the other end of the connecting rod and can be adsorbed and connected with a workpiece.

[0005] As described above, by slidably connecting one end of the connecting rod to the mounting bracket, when the suction head located at the other end of the connecting rod adsorbs the workpiece, the suction heads on different suction devices can absorb the height difference generated by the inclination of the workpiece through the sliding of the connecting rod on the mounting bracket. Thus, when the workpiece is inclined, the suction heads of different suction devices can be attached to the workpiece, thereby improving the stability and firmness of the adsorption connection with the workpiece and enhancing the feeding speed and production safety. In addition, by providing a first elastic member between the connecting rod and the mounting bracket, the suction head can be driven to return to its original position after being separated from the workpiece, so that the suction head can more easily adsorb the next workpiece, thereby increasing the feeding speed.

[0006] In some embodiments, the other end of the connecting rod is hinged to the suction head.

[0007] As described above, by hinging the other end of the connecting rod to the suction head, the suction head can be rotated on the connecting rod. Thus, when the workpiece is inclined, by rotating the suction head accordingly, the attachment effect between the suction head and the workpiece can be improved, and further the stability and firmness of the adsorption connection between the suction head and the workpiece can be enhanced.

[0008] In some embodiments, two connecting rods are provided, the two connecting rods are vertically arranged, respectively located on both sides of the suction head, and the other ends of the two connecting rods are hinged to the suction head on the first axis.

[0009] As described above, by providing two connecting rods on both sides of the suction head, the stability of the suction head can be improved.

[0010] In some embodiments, the suction device further includes: a second elastic member, the second elastic member is arranged between the suction head and the connecting rod, and after the suction head rotates on the connecting rod, the suction head is driven to return to the position before rotation.

[0011] As described above, by providing the second elastic member, after the suction head is separated from the workpiece, the suction head can be driven to return to the position before rotation, so that the suction head can more easily adsorb the next workpiece, thereby increasing the feeding speed.

[0012] In some embodiments, the second elastic member is a torsion spring, the torsion spring is arranged on the suction head, and two end portions of the torsion spring extend towards the connecting rod to form two toggle levers, and the connecting rod is located between the two toggle levers.

[0013] As described above, by arranging the connecting rod between the two toggle levers of the torsion spring, no matter which side the suction head rotates towards, it can be driven by the toggle levers to return to its original position, so that the suction head can more easily adsorb the next workpiece, thereby increasing the feeding speed.

[0014] In some embodiments, a mounting post and a positioning post are provided at the top end of the suction head. The torsion spring is sleeved on the mounting post, and the positioning post is located between the two lever arms.

[0015] As described above, a specific mounting structure of the torsion spring is provided. By providing the positioning post, the torsion spring can be prevented from rotating on the mounting post.

[0016] In some embodiments, the first elastic member is a spring, and the spring is sleeved on the connecting rod.

[0017] In some embodiments, a protection device is further included. The protection device is arranged on the mounting frame and includes: a swing arm arranged on one side of a plurality of the suction devices; a support plate arranged on the swing arm and located below the suction head; a first motor drivingly connected to the support plate to drive the support plate to rotate on a horizontal plane.

[0018] As described above, by providing the support plate below the suction cup, when the suction head completes adsorption with the workpiece and moves under the drive of the displacement device, the support plate can rotate to the lower part of the workpiece under the drive of the first motor to provide protection for the workpiece. Thus, during the process of feeding the workpiece, if the workpiece is separated from the suction head, the support plate can hold up the workpiece to avoid the danger of the workpiece falling.

[0019] In some embodiments, one end of the swing arm is hinged to the mounting frame, and the support plate is arranged at the other end of the swing arm; the protection device further includes: a driving cylinder arranged on the mounting frame and drivingly connected to the swing arm to drive the swing arm to rotate.

[0020] As described above, when the support plate is not required to provide protection for the workpiece, the driving cylinder can be used to drive the swing arm to rotate, so that the swing arm and the support plate rotate to other positions to avoid affecting the feeding equipment.

[0021] In some embodiments, a plurality of the protection devices are arranged along the mounting frame.

[0022] As described above, by providing a plurality of protection devices, the stability of the workpiece can be improved after the workpiece falls onto the support plate, thereby avoiding the danger of the workpiece falling.

Thus, the phrases "in an embodiment" or "in embodiments" that appear throughout this specification do not necessarily all refer to the same embodiment, but may. Additionally, in one or more embodiments, the various specific features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those of ordinary skill in the art from this disclosure.

[0034] Next, with reference to the views, the specific structure of the loading device 10 in the embodiments of the present application will be described in detail.

[0035] Figure 1 is a schematic perspective view of the loading device 10 in the embodiments of the present application. As Figure 1 shown, the loading device 10 in the embodiments of the present application includes a displacement device 100, a suction device 200, and a protection device 300. Among them, the displacement device 100 has a mounting frame 110. The displacement device 100 can drive the mounting frame 110 to move in the horizontal and vertical directions and can also drive the mounting frame 110 to rotate. A plurality of suction devices 200 are provided and are mounted on the mounting frame 110 and arranged along the extending direction of the mounting frame 110. A plurality of protection devices 300 are provided and are mounted on the mounting frame 110 and arranged along the extending direction of the mounting frame 110. Specifically, the suction devices 200 and the protection devices 300 can be arranged uniformly in a straight line as Figure 1 shown.

[0036] Figure 2 is Figure 1 a partial enlarged view of the area of the suction device 200 in. As Figure 2 shown, the suction device 200 includes a connecting rod 210, a first elastic member 220, and a suction head 230. Among them, the connecting rod 210 is vertically provided on the mounting frame 110. One end of the connecting rod 210 is slidably connected to the mounting frame 110. One end of the first elastic member 220 is connected to the mounting frame 110, and the other end is connected to the connecting rod 210. The first elastic member 220 can drive the connecting rod 210 to move downward through elastic force after the connecting rod 210 slides upward. The suction head 230 is provided at the other end of the connecting rod 210 and can be adsorbed and connected to the workpiece 20.

[0037] Specifically, the first elastic member 220 can be, for example, Figure 2 the spring 221 shown in the figure. The spring 221 is sleeved on the connecting rod 210. The spring 221 can be located Figure 2 below the mounting bracket 110 as shown in the figure. The upper end of the spring 221 abuts against the mounting bracket 110, and the lower end of the spring 221 abuts against the connecting rod 210. After the connecting rod 210 slides upward, the spring 221 is in a compressed state, driving the connecting rod 210 to move downward. Alternatively, the spring 221 can also be located above the mounting bracket 110. The lower end of the spring 221 abuts against the mounting bracket 110, and the upper end of the spring 221 abuts against the connecting rod 210. After the connecting rod 210 slides upward, the spring 221 is in a stretched state, driving the connecting rod 210 to move downward. In some embodiments, the first elastic member 220 can also be a spring leaf 221, a rubber band, or other elastic components, and there is no limitation thereto.

[0038] The suction head 230 can adsorb the workpiece 20 by the magnetism generated by electromagnetism or permanent magnetism, or can also adsorb the workpiece 20 by the vacuum generated by the suction cup, and there is no limitation thereto.

[0039] Thus, by slidably connecting one end of the connecting rod 210 to the mounting bracket 110, when the suction head 230 at the other end of the connecting rod 210 adsorbs the workpiece 20, the suction heads 230 on different suction devices 200 can absorb the height difference generated by the inclination of the workpiece 20 through the sliding of the connecting rod 210 on the mounting bracket 110. Therefore, when the workpiece 20 is inclined, the suction heads 230 of different suction devices 200 can all be attached to the workpiece 20, thereby improving the stability and firmness of the adsorption connection with the workpiece 20, and enhancing the loading speed and production safety. In addition, by providing the first elastic member 220 between the connecting rod 210 and the mounting bracket 110, the suction head 230 can be driven to return to its original position after being separated from the workpiece 20, so that the suction head 230 can more easily adsorb the next workpiece 20, thereby improving the loading speed.

[0040] As Figure 2 shown in the figure, the other end of the connecting rod 210 is hinged to the suction head 230. Thus, the suction head 230 can rotate on the connecting rod 210. Therefore, when the workpiece 20 is inclined, by correspondingly rotating the suction head 230, the attachment effect between the suction head 230 and the workpiece 20 can be improved, and further the stability and firmness of the adsorption connection between the suction head 230 and the workpiece 20 are improved.

[0041] As Figure 2 shown in the figure, two connecting rods 210 can be provided. The two connecting rods 210 are vertically arranged on both sides of the suction head 230 respectively. The other ends of the two connecting rods 210 are hinged to the suction head 230 on the first axis. Thus, the stability of the suction head 230 can be improved.

[0042] As shown Figure 2 in FIG. 2, the suction device 200 further includes a second elastic member 240. The second elastic member 240 is disposed between the suction head 230 and the connecting rod 210. After the suction head 230 rotates on the connecting rod 210, the second elastic member 240 drives the suction head 230 to return to the position before rotation. Thus, by providing the second elastic member 240, after the suction head 230 is separated from the workpiece 20, the second elastic member 240 can drive the suction head 230 to return to the position before rotation, so that the suction head 230 can more easily adsorb the next workpiece 20, thereby improving the loading speed.

[0043] As shown Figure 2 in FIG. 3, the second elastic member 240 is a torsion spring 241. The torsion spring 241 is disposed on the suction head 230. Two ends of the torsion spring 241 extend toward the connecting rod 210 to form two lever arms 242. The connecting rod 210 is located between the two lever arms 242. An installation post 231 and a positioning post 232 are provided at the top end of the suction head 230. The torsion spring 241 is sleeved on the installation post 231. The positioning post 232 is located between the two lever arms 242. Thus, by providing the positioning post 232, the torsion spring 241 can be prevented from rotating on the installation post 231. By disposing the connecting rod 210 between the two lever arms 242 of the torsion spring 241, no matter which side the suction head 230 rotates toward, the suction head 230 can be driven by the lever arms 242 to return to the original position, so that the suction head 230 can more easily adsorb the next workpiece 20, thereby improving the loading speed.

[0044] Furthermore, the second elastic member 240 may also be an elastic component such as a spring leaf 221 or a rubber band, and is not limited thereto.

[0045] Figure 3 FIG. 4 Figure 1 is a partial enlarged view of the area of the protection device 300. As shown Figure 3 in FIG. 4, the protection device 300 is disposed on the mounting bracket 110 and includes a swing arm 310, a support plate 320, and a first motor 330. Among them, the swing arm 310 is disposed on one side of a plurality of suction devices 200. The support plate 320 is disposed on the swing arm 310 and is located below the suction head 230. The first motor 330 is in transmission connection with the support plate 320 and drives the support plate 320 to rotate on a horizontal plane.

[0046] Specifically, as shown Figure 3 in FIG. 4, the upper end of the swing arm 310 is connected to the mounting bracket 110. The first motor 330 is disposed at the lower end of the swing arm 310. A driving shaft of the first motor 330 extends downward. The support plate 320 is fixed to the driving shaft of the first motor 330, and the first motor 330 directly drives the support plate 320 to rotate. Alternatively, the support plate 320 may also be directly hinged to the swing arm 310, and the first motor 330 drives the support plate 320 to rotate on the swing arm 310, and is not limited thereto.

[0047] As described above, by providing a supporting plate 320 below the suction cup, when the suction head 230 completes the adsorption of the workpiece 20 and moves under the drive of the displacement device 100, the supporting plate 320 can rotate under the drive of the first motor 330 to the lower part of the workpiece 20 to provide protection for the workpiece 20. Thus, during the process of loading the workpiece 20, if the workpiece 20 is separated from the suction head 230, the supporting plate 320 can lift the workpiece 20 to avoid the danger of the workpiece 20 falling.

[0048] As Figure 3 shown, one end of the swing arm 310 is hinged to the mounting frame 110, and the supporting plate 320 is arranged at the other end of the swing arm 310. The protection device 300 further includes a first driving cylinder 340, which is arranged on the mounting frame 110 and is in transmission connection with the swing arm 310 to drive the swing arm 310 to rotate. Specifically, the rear end of the first driving cylinder 340 is hinged to the mounting frame 110, and the driving rod of the first driving cylinder 340 is hinged to the swing arm 310. The first driving cylinder 340 can drive the swing arm 310 to rotate by driving the driving rod to extend or retract. Thus, when the supporting plate 320 does not need to provide protection for the workpiece 20, the swing arm 310 can be driven to rotate by the driving cylinder, so that the swing arm 310 and the supporting plate 320 rotate to other positions to avoid affecting the loading device 10.

[0049] As Figure 1 shown, a plurality of protection devices 300 are arranged along the mounting frame 110. Thus, after the workpiece 20 falls onto the supporting plate 320, the stability of the workpiece 20 can be improved, thereby avoiding the danger of the workpiece 20 falling.

[0050] Figure 4 For Figure 1 the partial enlarged view of the displacement device 100 area in Figure 1 、 Figure 4 shown, the displacement device 100 includes a mounting frame 110, a cross beam 120, a first moving frame 130, a second moving frame 140, a second motor 150, a third motor 160 and a second driving cylinder 170. Among them, the mounting frame 110 is horizontally arranged at the lower end position of the first moving frame 130 and is hinged to the first moving frame 130. The second motor 150 is arranged on the first moving frame 130 and can be in transmission connection with the mounting frame 110 by means of gears, chains or belts. When the second motor 150 rotates, it can drive the mounting frame 110 to rotate, so that the suction head 230 on the mounting frame 110 can be aligned with the workpiece 20.

[0051] The first moving frame 130 is disposed on the second moving frame 140 and is slidably connected to the second moving frame 140 in the vertical direction. The second driving cylinder 170 is disposed on the second moving frame 140 and is drivingly connected to the first moving frame 130, and can drive the first moving frame 130 to move up and down on the second moving frame 140. The second driving cylinder 170 can be an electric cylinder, a hydraulic cylinder or a pneumatic cylinder, and there is no limitation thereto. Thus, by driving the first moving frame 130 to move downward, the suction head 230 on the mounting frame 110 can be moved downward so that the suction head 230 can adhere to the workpiece 20 to adsorb the workpiece 20. After the adsorption is completed, by driving the first moving frame 130 to move upward, the workpiece 20 can be lifted by the suction head 230.

[0052] The second moving frame 140 is disposed on the cross beam 120 and is slidably connected to the cross beam 120 in the horizontal direction. The third motor 160 is disposed on the second moving frame 140, and the second moving frame 140 is driven to slide on the cross beam 120 by the third motor 160. Specifically, a rack can be disposed along the cross beam 120, a gear can be disposed on the drive shaft of the third motor 160, and the gear meshes with the rack, so that when the third motor 160 rotates, the second moving frame 140 can be driven to move on the cross beam 120. Thus, the second moving frame 140 can be driven to drive the mounting frame 110 and the suction head 230 on the mounting frame 110 to move above the workpiece 20 for adsorbing the workpiece 20. After the adsorption is completed, the second moving frame 140 can also be driven to drive the workpiece 20 to move to a position such as a conveying roller or a workbench, so as to place the workpiece 20 at a predetermined position.

[0053] In summary, when using the feeding device 10 in the present application to feed the workpiece 20, the second moving frame 140 can be driven to move on the cross beam 120 by the third motor 160, so that the mounting frame 110 moves to the position where the workpiece 20 is stacked. The second motor 150 drives the mounting frame 110 to rotate on the first moving frame 130, so that the mounting frame 110 and the workpiece 20 are in the same vertical plane. The second driving cylinder 170 drives the first moving frame 130 to move downward, so that the suction head 230 on the mounting frame 110 adheres to the upper surface of the workpiece 20. After the suction head 230 is adsorbed and connected to the workpiece 20, the second driving cylinder 170 drives the first moving frame 130 to move upward, thereby lifting the workpiece 20. The first driving cylinder 340 drives the swing arm 310 to rotate, so that the height of the support plate 320 is lower than that of the workpiece 20. The first motor 330 rotates to drive the support plate 320 to rotate to a position below the workpiece 20 to provide protection for the workpiece 20.

[0054] The third motor 160 drives the second moving frame 140 to move on the cross beam 120, so that the workpiece 20 can be moved above a predetermined position such as a conveying roller or a workbench. The second motor 150 drives the mounting frame 110 to rotate on the first moving frame 130, so as to drive the workpiece 20 to rotate to a predetermined angle. The first motor 330 rotates to drive the support plate 320 to rotate, so that the support plate 320 is moved out from below the workpiece 20 to avoid affecting the placement of the workpiece 20. The first driving cylinder 340 drives the swing arm 310 to rotate, and rotates the support plate 320 to a higher position, so as to further avoid affecting the placement of the workpiece 20. The second driving cylinder 170 drives the first moving frame 130 to move downward, so as to place the workpiece 20 at a predetermined position. After the suction head 230 finishes the adsorption connection with the workpiece 20, the second driving cylinder 170 drives the first moving frame 130 to move upward, so that the suction head 230 is separated from the workpiece 20. Thus, the loading of the workpiece 20 is completed.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
