[0041] This application provides a conveying device 1 for conveying thin metal sheet workpieces.

[0042] The conveying device 1 includes a frame 11, a transverse conveying device 12, a magnetic suction device 14, and a clamping device 15. The transverse conveying device 12 is mounted on the frame 11 and can move laterally relative to the frame 11. The magnetic suction device 14 and the clamping device 15 are both located on the transverse conveying device 12 and can move laterally with the transverse conveying device 12. The top surface of the magnetic suction device 14 has a supporting plane 1412, which can be used to place the workpiece after loading. The magnetic suction device 14 is configured to attract the workpiece located on the supporting plane 1412 under magnetic attraction. The clamping device 15 includes a power member 151 and a clamping member 152. The power member 151 is configured to drive the clamping member 152 downward toward the supporting plane 1412 to clamp the workpiece located on the supporting plane 1412, or drive the clamping member 152 upward away from the supporting plane 1412 to release the workpiece located on the supporting plane 1412. When the clamping device 15 clamps the workpiece located on the supporting plane 1412, the transverse conveying device 12 can move laterally to convey the workpiece.

[0043] During the feeding process of the conveying equipment 1 in this application, the thin metal sheet workpiece is first placed on the supporting plane 1412, so that the magnetic suction device 14 adsorbs and positions the workpiece on the supporting plane 1412. Then, the power component 151 of the clamping device 15 drives the clamping component 152 to press down on the workpiece on the supporting plane 1412, thus clamping and fixing the workpiece. After the workpiece is fixed on the supporting plane 1412, the transverse conveying device 12 can move laterally relative to the frame 11 to convey the workpiece. Under the magnetic positioning of the magnetic suction device 14 and the clamping and fixing of the clamping device 15, the workpiece can reduce the shaking and slippage during the conveying process, overcome the problem that the thin metal sheet workpiece is difficult to clamp due to its poor rigidity and easy deformation and instability under stress, and improve the stability of the workpiece conveying process.

[0044] Figure 1 A schematic diagram of the conveying device 1 is shown. Figure 2 A partial structural diagram of the conveying device 1 is shown.

[0045] Reference Figure 1 and Figure 2 The conveying equipment 1 includes a frame 11 and a transverse conveying device 12. In fact, the frame 11 has a feeding side 111 and a discharging side 112 spaced apart in the transverse direction.

[0046] For ease of description, the width direction of the rack 11 is defined as the horizontal direction, and the length direction is defined as the vertical direction.

[0047] The transverse conveying device 12 is mounted on the frame 11 and can reciprocate transversely between the loading side 111 and the unloading side 112 relative to the frame 11, thereby driving the workpiece to move transversely under the positioning of the magnetic suction device 14 and the clamping device 15.

[0048] The transverse conveying device 12 includes a transverse drive component 121 and a transverse moving frame 122. The transverse drive component 121 is disposed on the frame 11, and the transverse moving frame 122 is slidably connected to the frame 11 in a transverse direction. The transverse drive component 121 drives the two transverse moving frames 122 to move transversely relative to the frame 11. A magnetic suction device 14 and a pressing device 15 are located on the transverse moving frame 122, so that the magnetic suction device 14 and the pressing device 15 can move transversely relative to the frame 11 with the transverse moving frame 122.

[0049] Specifically, the lateral drive component 121 may include a motor and a lateral lead screw 1211. The lateral lead screw 1211 extends laterally and is fixed to the frame 11. The lateral moving frame 122 is connected to the lateral lead screw 1211 via a lead screw nut. The motor can drive the lateral lead screw 1211 to rotate, thereby causing the lateral moving frame 122 to slide laterally relative to the frame 11. The frame 11 shown in the figure has two spaced-apart lateral slide rails 123, which extend laterally. The lateral moving frame 122 has sliders that slide in cooperation with the lateral slide rails 123, improving the smoothness of movement of the lateral moving frame 122. In this embodiment, the two lateral slide rails 123 are located on both sides of the lateral lead screw 1211, further improving the smoothness of movement of the lateral moving frame 122.

[0050] In other embodiments, the lateral drive 121 may also be an actuator such as a cylinder or hydraulic cylinder, or a transmission mechanism such as a gear, chain / belt may be used to achieve lateral linear drive of the lateral moving frame 122.

[0051] The transverse conveying device 12 of this embodiment includes two transverse moving frames 122 arranged longitudinally at intervals. Specifically, both the longitudinal and transverse directions extend horizontally and are perpendicular to each other. By distributing the two transverse moving frames 122 on opposite sides of the longitudinal interval, and each transverse moving frame 122 having a magnetic suction device 14 and a clamping device 15, the conveying device 1 can simultaneously clamp and convey the workpiece on both sides of the longitudinal direction, further improving the stability of workpiece conveying. The transverse drive component 121 can be configured as two sets of motors to drive the two transverse drive frames laterally, or the two transverse moving frames 122 can be fixedly connected by a structure, in which case a combination of a motor, pulley, and synchronous belt can be used to simultaneously drive the two transverse drive frames laterally.

[0052] Furthermore, the conveying device 1 also includes a vertical conveying device 13. The vertical conveying device 13 is disposed on the horizontal conveying device 12 and can move vertically relative to the horizontal conveying device 12. The magnetic suction device 14 and the pressing device 15 are disposed on the vertical conveying device 13 and can move vertically with the vertical conveying device 13. Herein, vertical refers to the up and down direction shown in the figure.

[0053] The vertical conveying device 13 is mounted on the horizontal conveying device 12, and the magnetic suction device 14 and the pressing device 15 are mounted on the vertical conveying device 13. The magnetic suction device 14 and the pressing device 15 can move horizontally and vertically relative to the frame 11, which facilitates the loading of workpieces and can simultaneously drive the workpieces to be conveyed horizontally and vertically, thereby facilitating the unloading of workpieces and reducing interference with other components.

[0054] In this embodiment, the vertical conveying device 13 includes a vertical drive member 131 and a vertical moving frame 132. The vertical drive member 131 is disposed on the horizontal conveying device 12, and the vertical moving frame 132 is slidably connected to the horizontal conveying device 12 in a vertical direction. The vertical drive member 131 drives the vertical moving frame 132 to move vertically relative to the horizontal conveying device 12.

[0055] Specifically, the vertical drive component 131 may include a motor and a vertical lead screw. The vertical lead screw extends vertically and is fixed to the horizontal moving frame 122. The vertical moving frame 132 is connected to the vertical lead screw via a lead screw nut. The motor can drive the vertical lead screw to rotate, thereby causing the vertical moving frame 132 to slide vertically relative to the horizontal moving frame 122. The illustrated horizontal moving frame 122 is provided with two spaced vertical slide rails 133, which extend vertically. The vertical moving frame 132 is provided with a slider that slides with the vertical slide rails 133, improving the smoothness of movement of the vertical moving frame 132. In this embodiment, the two vertical slide rails 133 are located on both sides of the vertical lead screw, further improving the smoothness of movement of the vertical moving frame 132. Furthermore, the vertical drive component 131 may also be an actuator such as a cylinder, or a transmission mechanism such as a motor, gears, or belts may be used to achieve vertical linear drive of the vertical moving frame 132.

[0056] In a specific embodiment, the vertical conveying device 13 includes two vertical moving frames 132, which are respectively disposed on two horizontal moving frames 122, and the two vertical moving frames 132 move synchronously.

[0057] Figure 3 and Figure 4 A partial schematic diagram of the conveying device 1 is shown.

[0058] Reference Figures 1 to 4 Furthermore, the conveying device 1 also includes a magnetic suction device 14, which is located on the transverse conveying device 12 and can move laterally with it. A supporting plane 1412 is formed on the top surface of the magnetic suction device 14, which is configured to attract workpieces located on the supporting plane 1412 under magnetic attraction. The workpiece can be positioned by the magnetic attraction of the magnetic suction device 14, overcoming the problem of difficulty in clamping the workpiece due to its poor rigidity and tendency to deform and become unstable under stress, thus improving the stability of workpiece conveying.

[0059] In this embodiment, the magnetic suction device 14 includes two magnetic suction groups 141 arranged longitudinally at intervals. The two magnetic suction groups 141 are used to attract the longitudinally opposite sides of the workpiece. Each magnetic suction group 141 includes at least one magnetic suction element 1411. The top surfaces of all magnetic suction elements 1411 are located on the same plane and form a supporting plane 1412.

[0060] Two longitudinally spaced magnetic traction groups 141 can attract the workpiece from opposite sides along its longitudinal direction, improving the stability of the workpiece support and increasing the number of magnetic attraction points, thus reducing the occurrence of workpiece slippage and misalignment. Each magnetic traction group 141 includes at least one magnetic element 1411, and the top surfaces of all magnetic elements 1411 are on the same plane, forming a support plane 1412. The support plane 1412 can be considered as a complete plane enclosed by the top surfaces of multiple magnetic elements 1411, and the support plane 1412 extends horizontally, so that the top surfaces of multiple magnetic elements 1411 can both support the workpiece and achieve the attraction and positioning of the workpiece.

[0061] In this embodiment, a magnetic suction group 141 is located on a transverse moving frame 122. Specifically, each transverse moving frame 122 has a magnetic suction group 141, and the two magnetic suction groups 141 are driven to move by the two transverse moving frames 122 respectively, so as to realize the synchronous movement of the two magnetic suction groups 141.

[0062] In fact, the magnetic suction component 1411 is set on the vertical conveying device 13, specifically on the vertical moving frame 132. The two magnetic suction groups 141 are respectively set on the two vertical moving frames 132, so that multiple magnetic suction components 1411 can move up and down synchronously with the two vertical moving frames 132.

[0063] Furthermore, a magnetic suction group 141 includes at least two magnetic suction elements 1411 arranged laterally at intervals. The at least two magnetic suction elements 1411 on each magnetic suction group 141 can be arranged at intervals along the lateral edge extension direction of the workpiece, which can increase the magnetic suction positioning area between the magnetic suction elements 1411 and the workpiece, further improve the support and magnetic suction positioning effect of the workpiece, and reduce the possibility of the workpiece being misaligned and slipping during the clamping and conveying process.

[0064] In this embodiment, the magnetic suction element 1411 is cylindrical with a top flat surface, which can be used to attract and support workpieces. A magnetic suction group 141 may include multiple magnetic suction elements 1411. Among the multiple magnetic suction elements 1411, all of them can be arranged at intervals along the lateral direction to adhere to the lateral edge of the workpiece for attraction and support, or at least two magnetic suction elements 1411 can be arranged at intervals along the longitudinal direction to improve the support and attraction effect on the workpiece.

[0065] In some other embodiments, a magnetic assemblies 141 may include only one magnetic element 1411. Furthermore, the magnetic device 14 may include a support bracket, with the magnetic element 1411 and the support bracket offset from each other. The top surface of the magnetic element 1411 and the top surface of the support bracket together form a support plane 1412. Additionally, a single magnetic element 1411 may be elongated, rectangular, or similar, increasing the contact area between the magnetic element 1411 and the workpiece, thereby enhancing the adsorption and support effect on the workpiece.

[0066] In this embodiment, the magnetic suction element 1411 is an electromagnet. When the workpiece is loaded onto the supporting surface 1412, the power to the magnetic suction element 1411 is turned on. At this time, the magnetic suction element 1411 has a magnetic attraction effect, which can attract the workpiece, improve the stability of the workpiece after loading, and reduce workpiece misalignment. When the workpiece needs to be unloaded from the supporting surface 1412, the power to the magnetic suction element 1411 is turned off. At this time, the magnetic suction element 1411 releases its magnetic attraction to the workpiece, making it easier for the workpiece to detach from the supporting surface 1412 and facilitating workpiece unloading. In some other embodiments, the magnetic suction element 1411 can also be a magnet.

[0067] Furthermore, the conveying device 1 also includes a clamping device 15, which is located on the transverse conveying device 12 and can move laterally with the transverse conveying device 12. The clamping device 15 includes a power component 151 and a clamping component 152.

[0068] The power unit 151 can be configured to drive the clamping member 152 downward toward the supporting plane 1412 to clamp the workpiece located on the supporting plane 1412. For example... Figure 3 As shown, at this time, the clamping member 152 is in the state of pressing the workpiece on the supporting plane 1412 downward.

[0069] Alternatively, the power unit 151 can be configured to drive the clamping member 152 upward away from the supporting plane 1412 to release the workpiece located on the supporting plane 1412. For example... Figure 4 As shown, the clamping member 152 is in a state of moving upward away from the supporting plane 1412 at this time.

[0070] Furthermore, the clamping member 152 includes a pressure block 1521, which is positioned directly above at least one magnetic member 1411, as the clamping member 152 presses the workpiece on the supporting plane 1412 with the pressure block 1521.

[0071] The clamping member 152 contacts and clamps the workpiece through the clamping block 1521. When clamping the workpiece, the clamping block 1521 can face at least one magnetic suction member 1411, so that the upper and lower sides of the workpiece can be clamped by the clamping block 1521 and the magnetic suction member 1411 at the same time, achieving the clamping effect of the workpiece and further improving the positioning stability of the workpiece.

[0072] In other embodiments, when the pressure block 1521 presses the workpiece, the pressure block 1521 and the magnetic suction member 1411 may be vertically offset, as long as the position of the pressure block 1521 is within the supporting plane 1412 formed by the top surfaces of the multiple magnetic suction members 1411. Specifically, the pressure block 1521 may be located between two longitudinally adjacent magnetic suction members 1411, or between two laterally adjacent magnetic suction members 1411.

[0073] The pressure block 1521 in this embodiment can be made of materials such as plastic or rubber to avoid scratching the surface of the workpiece.

[0074] Furthermore, the clamping member 152 includes an adjusting arm 1522 spaced apart on one side of the support plane 1412, a pressure block 1521 connected to the adjusting arm 1522, and a power member 151 connected to the adjusting arm 1522. The power member 151 drives the adjusting arm 1522 to move, thereby causing the pressure block 1521 to press down on the workpiece or move upward away from the workpiece.

[0075] Specifically, the power component 151 rotates to drive one axial end of the adjusting arm 1522, and the pressure block 1521 is disposed at the other axial end of the adjusting arm 1522. The power component 151 can drive the end of the adjusting arm 1522 with the pressure block 1521 to rotate downward relative to the supporting plane 1412, so that the pressure block 1521 presses against the supporting plane 1412; or the power component 151 can drive the end of the adjusting arm 1522 with the pressure block 1521 to rotate upward relative to the supporting plane 1412, so that the pressure block 1521 moves away from the supporting plane 1412, and after the adjusting arm 1522 rotates upward, the adjusting arm 1522 can rotate so that the pressure block 1521 is spaced apart on one side of the supporting plane 1412. By driving the adjusting arm 1522 to rotate by the power component 151, it can be moved above the supporting plane 1412 when the workpiece is being loaded, making it easier for the workpiece to be loaded onto the supporting plane 1412 of the magnetic suction device 14. In addition, the power component 151 can be an electric motor or a rotary cylinder, etc.

[0076] In fact, the power component 151 is set on the vertical moving frame 132, and the clamping component 152 is positioned on the vertical moving frame 132 through the power component 151, so that the clamping device 15 can move up and down relative to the horizontal moving frame 122 with the vertical moving frame 132.

[0077] In some other embodiments, the power component 151 may also be a linear drive component, used to directly drive the clamping component 152 to move up and down, thereby moving upward away from or downward towards the supporting plane 1412.

[0078] In a specific embodiment, the clamping device 15 and the magnetic suction device 14 move synchronously. The clamping device 15 is located on the side of the magnetic suction device 14 that is close to the feeding side 111 in the lateral direction, so that the clamping block 1521 of the clamping device 15 can cooperate with the magnetic suction component 1411 to clamp the workpiece on the lateral side of the feeding side 111, thereby achieving lateral clamping of the workpiece. Meanwhile, the lateral side of the workpiece that is close to the unloading side 112 is suspended, which makes it easier to place the workpiece on the subsequent molding equipment 3 and prevents interference.

[0079] Furthermore, the conveying equipment 1 also includes a transfer support 16 and a transfer device 17.

[0080] like Figure 1As shown, the transfer bracket 16 is mounted on the frame 11, and its top has a support surface for supporting the workpiece. The transverse conveying device 12 moves laterally relative to the frame 11 between the loading side 111 and the unloading side 112, with the transfer bracket 16 located on the transverse side of the loading side 111 away from the unloading side 112. The support surface of the transfer bracket 16 can temporarily hold the workpiece, facilitating its transfer.

[0081] The support surface is located above the supporting surface, which facilitates the flipping of the workpiece. That is, the workpiece is transferred to the support surface by the transfer device 17, and then the workpiece is flipped and placed on the supporting surface by the action of the transfer device 17.

[0082] Preferably, the support surface is inclined from top to bottom towards the loading side. This inclined surface facilitates the flipping of the workpiece. In this embodiment, the support surface forms an upward angle. The transfer device 17 has a clamping end for holding the workpiece. Specifically, the transfer device 17 can be a robotic arm, which facilitates the gripping of the workpiece in a limited space. The clamping end can be a suction cup for gripping the workpiece. Furthermore, the transfer device 17 can be mounted on the frame 11 or set independently relative to the frame 11.

[0083] During operation, the transfer device 17 is configured to clamp the workpiece, after being bent by the molding equipment 3, onto the support surface of the transfer bracket 16 via the clamping end. Then, the workpiece on the support surface is clamped, flipped, and placed onto the supporting plane 1412 located on the loading side 111. Specifically, the transfer device 17 can flip the workpiece on the transfer bracket 16 180° via the clamping end, facilitating bending and other processing on the other side of the workpiece, thus satisfying various workpiece processing needs.

[0084] Reference Figure 5 This application also provides a bending machine, which includes a feeding device 2, a molding device 3 and the aforementioned conveying device 1.

[0085] The feeding device 2, the molding device 3, and the conveying device 1 are arranged sequentially along the transverse direction. The feeding device 2 is located on one side of the molding device 3 and is configured to feed the workpiece onto the molding device 3. The molding device 3 is configured to bend the workpiece.

[0086] Specifically, the feeding device 2 can feed a single sheet metal workpiece onto the molding device 3 through the individual operation or cooperation of devices such as conveyor belts and pushers. The molding device 3 has a bottom mold 31 and a top pressing component 32 that is positioned downwards and directly opposite the bottom mold 31. After the sheet metal workpiece enters between the bottom mold 31 and the top pressing component 32, it is pressed down by the top pressing component 32 to achieve the bending process of the sheet metal workpiece.

[0087] The conveying device 1 is located on the other side of the molding equipment 3. The magnetic suction device 14 is configured to attract the bent workpiece and convey the bent workpiece laterally to the molding equipment 3 for re-bending via the transverse conveying device 12.

[0088] Specifically, the side of the frame 11 furthest from the molding equipment 3 is the loading side 111, and the side of the frame 11 closest to the molding equipment 3 is the unloading side 112. After the thin sheet workpiece entering from the feeding device 2 is bent on the molding equipment 3, it is picked up by the transfer device 17 and placed on the opening of the transfer bracket 16. Then, the transfer device 17 flips the workpiece and places it on the supporting plane 1412 of the magnetic suction device 14 for magnetic positioning, and the clamping member 152 of the clamping device 15 clamps and fixes the workpiece. Next, the horizontal conveying device 12 horizontally moves the fixed workpiece from the loading side 111 to the unloading side 112, while the vertical conveying device 13 adjusts the vertical position of the workpiece to facilitate its entry into the molding equipment 3 for further bending. After the horizontal conveyor 12 and the vertical conveyor 13 work together to convey the workpiece to the molding equipment 3, it returns to the loading side 111 of the frame 11, waiting for the transfer device 17 to place the next bent workpiece from the transfer bracket 16 onto the supporting plane 1412 of the magnetic suction device 14. This allows the conveyor 1 in this embodiment to serve as a transfer and reloading device for bent workpieces, facilitating the transfer and repositioning of workpieces, and making it easier to reload and bend workpieces again.
