[0003] In the prior art, the patent document with authorization announcement number CN224074979U discloses a frame bending device, including a worktable, a pressing structure, a guide rod, a cylinder and a placement platform; the worktable has an installation cavity, in which a cooling pipe is fixedly installed; an installation block is fixedly installed on the side wall of the worktable, and a conveying pipe is fixedly installed on the installation block; the installation block has a connecting groove, and the two ends of the connecting groove are respectively connected to the water inlet end of the cooling pipe and the conveying pipe; the installation block has a scale inhibition device, which can prevent the formation of scale on the water cooling pipe.

[0004] The existing frame bending equipment requires shutdown to replenish the sheet metal after it runs out, leading to production interruptions, low equipment utilization, and unsuitability for large-scale continuous production. Therefore, it is necessary to improve this structure to overcome the above-mentioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a bending device and method for mirror frame panels, which solves the problem that existing mirror frame bending devices must stop to replenish panels after the panels are used up, resulting in production interruption and low equipment utilization.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A bending device for picture frame panels, comprising:

[0008] Placement unit, used to place the frame material plates to be processed;

[0009] A material support unit is located at one end of the placement unit and is used to support the frame material plate of the placement unit;

[0010] The material handling unit is located at one end opposite to the placement unit and the material support unit. It is used to grab the picture frame material plate from the placement unit and transport it.

[0011] The receiving unit is located on the side of the placement unit near the picking unit and is used to receive the frame material plate;

[0012] The bending unit is located on the side of the placement unit close to the material taking unit and above the receiving unit, and is used to bend the frame material of the receiving unit.

[0013] The conveying unit, located in the bending unit, is used to remove the bent frame material from the receiving unit.

[0014] A further configuration of the present invention is that the placement unit includes:

[0015] Place a support bracket to provide support;

[0016] A shaping base, the upper end face of which is provided with a shaping mold groove;

[0017] The material rack is set on the placement support, and its two ends are respectively provided with receiving cavities for stacking mirror frame material plates.

[0018] A further configuration of the present invention is that the material support unit includes:

[0019] A material support plate is positioned between the placement bracket and the material rack, and the lower surface of the material support plate slides in conjunction with the placement bracket via a material support slide rail.

[0020] The material-supporting cylinder is installed on the placement bracket and connected to one end of the material-supporting plate. It is used to drive the material-supporting plate to move axially along the material-supporting slide rail and can selectively support one or both of the receiving cavities at both ends.

[0025] The material-grabbing clamps are arranged symmetrically and connected to the two output ends of the material-grabbing cylinder respectively. The material-grabbing clamps have limit notches. When the material-grabbing cylinder drives the two material-grabbing clamps to move towards each other until they contact, the limit notches form a limit groove for accommodating the frame material plate.

[0026] The material handling drive assembly has its drive end connected to the material handling slider, which is used to drive the material handling slider to move along the material handling guide rail and drive the material handling clamp to move.

[0027] A further feature of the present invention is that the placement unit further includes a rotating component, which is disposed on the placement bracket and connected to the material rack, for driving the material rack to rotate so as to realize the interchange of the positions of the receiving cavities at both ends of the material rack;

[0028] The rotating assembly includes: a lower shaft plate, located above the placement bracket, with a rotating shaft rotatably connected to the placement bracket on its lower end face;

[0029] The upper shaft plate is located above the lower shaft plate and is fixedly connected to the lower shaft plate via a connecting plate;

[0030] The rotary cylinder has its rotary output end connected to the upper shaft plate for transmission. The lower end of the material rack is fixedly connected to the lower shaft plate, and the upper end of the material rack is fixedly connected to the upper shaft plate. The rotary cylinder drives the upper shaft plate to rotate, which in turn drives the connecting plate and the lower shaft plate to rotate together, thereby driving the material rack to rotate and causing the positions of the receiving cavities at both ends of the material rack to be interchanged.

[0031] A further configuration of the present invention is that the receiving unit includes:

[0032] Guiding components are used to provide movement paths;

[0033] The receiving seat, located on the guide assembly, has a bending groove for accommodating the frame material plate;

[0034] The receiving drive assembly has its drive end connected to the receiving seat and is used to drive the receiving seat to move along the guide assembly.

[0035] A further configuration of the present invention is that the bending unit comprises:

[0036] Bending supports are used to provide support.

[0037] A shaping component is disposed on a bending bracket and located above a shaping seat on which the bracket is placed. The shaping component includes a shaping cylinder connected to a shaping plate. The shaping cylinder is used to drive the shaping plate to move and perform surface shaping on the frame material plate on the shaping seat.

[0038] A pre-compression assembly is set on a bending support. The pre-compression assembly includes a pre-compression cylinder, which is connected to a pre-compression block. The pre-compression cylinder is used to drive the pre-compression block to move and pre-compress the mirror frame plate on the material seat.

[0039] A bending assembly is mounted on a bending bracket. The bending assembly includes a bending cylinder connected to a bending block. The bending cylinder is used to drive the bending block to move and perform bending treatment on the mirror frame plate on the material holder.

[0040] The material feeding assembly includes a material feeding cylinder, which is mounted on the receiving seat. The material feeding cylinder is connected to one end of the material feeding rod, and the other end of the material feeding rod passes through the receiving seat and extends to the lower end face of the bending groove.

[0041] A further configuration of the present invention is that the conveying unit includes:

[0042] Transport stand, used to provide support;

[0043] Two movable guide rails are symmetrically arranged on the transport bracket, and the movable base slides with the movable guide rails;

[0044] A drive assembly, the drive end of which is connected to the movable base, is used to drive the movable base to move along the movable guide rail;

[0045] The lifting component is located on the movable base and can move synchronously with the movable base;

[0046] The clamping component is connected to the lifting end of the lifting component and can move up and down with the lifting end. It is used to clamp the frame material after bending.

[0047] A method of using a bending device for picture frame panels includes the following steps:

[0048] Material handling steps: Control the material support cylinder so that the material support plate only supports the receiving cavity on one side of the material rack, and the bottom frame material plate in the receiving cavity on the other side is placed into the limiting groove of the material handling clamp under the action of gravity;

[0049] Shaping Step: The material handling drive unit drives the material handling unit to transport the clamped frame material to the shaping seat. The material handling clamp releases the frame material, and the shaping component performs shaping processing on the frame material on the shaping seat.

[0050] Material receiving steps: The material receiving drive unit drives the material receiving seat to move below the pre-pressing component. The material picking clamp re-clamps the shaped mirror frame material plate. The material picking drive unit conveys it to the bending groove of the material receiving seat and releases it, so that the mirror frame material is placed into the bending groove.

[0051] Bending steps: The pre-pressing unit pre-presses the mirror frame material, the receiving drive drives the receiving seat to move below the bending assembly, and the bending unit performs the final bending of the mirror frame material.

[0052] Material lifting step: After bending is completed, the material lifting cylinder drives the material lifting rod to rise, lifting the finished mirror frame material plate in the bending groove upward, so that part of the mirror frame material plate is removed from the bending groove, making it easier for the handling unit to grab it;

[0053] Handling steps: After bending is completed, the receiving drive unit drives the receiving seat to move to the bottom of the handling unit, and the clamping component grabs the bent mirror frame material and moves it outward.

[0054] It also includes a rotation step:

[0055] Once all the picture frame plates in the receiving cavity near the material picking unit on one side of the material rack have been picked up, the rotating component drives the material rack to rotate, moving the receiving cavity on the other side above the material picking unit to achieve continuous material picking.

[0056] In summary, the present invention has the following beneficial effects:

[0057] Continuous material feeding is achieved through a rotating dual-station material rack. The orderly picking of frame panels is achieved through the coordinated action of the material support unit and the material picking unit. The frame panels are then shaped, pre-bent, and press-bent, realizing fully automated processing. Attached Figure Description

Detailed Implementation

[0068] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to the figures and specific embodiments.

[0069] like Figure 1 As shown, the present invention proposes a bending device for mirror frame panels, comprising: a worktable 100 for providing a supporting plane; a placement unit 200 disposed at one end of the worktable 100 for placing the mirror frame panel 101 to be processed; a material support unit 300 disposed at the placement unit 200 for supporting the mirror frame panel; a material pick-up unit 400 disposed at the placement unit 200 for conveying the mirror frame panel; a material receiving unit 500 disposed at the other end of the worktable 100 for receiving the mirror frame panel; a bending unit 600 disposed above the worktable 100 for bending the mirror frame; and a conveying unit 700 disposed above the bending unit 600 for conveying the bent mirror frame panel.

[0070] like Figure 2 As shown, specifically, the placement unit 200 includes a placement bracket 201, on which a material rack 202 for placing frame panels is provided. Each end of the material rack 202 has a receiving cavity 203, and each receiving cavity 203 is used to stack multiple frame panels. One end of the placement bracket 201 has a shaping seat 204, and the upper surface of the shaping seat 204 has a shaping mold groove.

[0071] like Figure 2 and Figure 3 As shown, the placement unit 200 also includes a rotating component, which is mounted on the placement bracket 201. The material rack 202 is connected to the rotating component and can rotate with the rotating component. When all the mirror frame plates on one side of the material rack 202 have been picked up by the material picking unit 400, the rotating component is started, driving the material rack 202 to rotate and move the mirror frame plates on the other end above the material picking unit 400, thereby realizing cyclic material picking.

[0072] Specifically, the rotating assembly includes a lower shaft plate 205, an upper shaft plate 207, and a rotary cylinder 209. The lower shaft plate 205 is located above the placement bracket 201, and a rotating shaft 206 is fixedly mounted on its bottom surface. The rotating shaft 206 passes downward through the placement bracket 201 and is rotatably connected to the placement bracket 201 via bearings. The upper shaft plate 207 is located above the lower shaft plate 205, and the upper shaft plate 207 and lower shaft plate 205 are fixedly connected via a connecting plate 208. The rotation output end of the rotary cylinder 209 is drively connected to the upper shaft plate 207. The lower end of the material rack 202 is fixedly connected to the lower shaft plate 205, and the upper end of the material rack 202 is fixedly connected to the upper shaft plate 207, thereby enabling the material rack 202 to rotate with the rotating assembly.

[0073] like Figure 4and Figure 5 As shown, specifically, the material support unit 300 includes a material support plate 301 and a material support cylinder 302. The material support plate 301 is disposed between the placement bracket 201 and the material rack 202. The upper surface of the material support plate 301 is used to support the frame material plate and prevent the material from falling when not being picked up. The lower surface of the material support plate 301 is slidably engaged with the placement bracket 201 through a material support slide rail 303. The material support cylinder 302 is installed on the placement bracket 201, and the piston rod of the material support cylinder 302 is connected to one end of the material support plate 301. The material support cylinder 302 can drive the material support plate 301 to move axially along the material support slide rail 303.

[0074] When the piston rod of the material-supporting cylinder 302 extends to its limit position, the material-supporting plate 301 is located only below one receiving cavity 203 of the material rack 202, supporting the frame panels inside that cavity 203. The other receiving cavity 203, located near the picking unit 400, is unsupported by the material-supporting plate 301, and the bottommost frame panel in that cavity enters the picking unit 400 below under gravity. When the piston rod of the material-supporting cylinder 302 retracts, the material-supporting plate 301 simultaneously moves to the bottom of both receiving cavities 203, supporting the frame panels in both cavities and preventing them from falling. This material-supporting assembly ensures that only one frame panel from one receiving cavity 203 is released at a time, guaranteeing orderly material handling.

[0075] like Figure 5 As shown, specifically, the material handling unit 400 includes a material handling guide rail 401, a material handling slider 402, a material handling cylinder 403, a material handling clamping plate 404, and a material handling drive assembly. Two material handling guide rails 401 are fixed parallel and symmetrically on the worktable 100, and the material handling slider 402 slides in cooperation with the material handling guide rails 401. In this embodiment, the material handling cylinder 403 is preferably a double-outlet cylinder, fixedly mounted on the material handling slider 402. Two material handling clamping plates 404 are symmetrically arranged and connected to the two output ends of the material handling cylinder 403 respectively. A limit notch 405 is provided at one end of each material handling clamping plate 404.

[0076] When the picking cylinder 403 drives the two picking clamps 404 to move towards each other until they contact, the two limiting notches 405 together form a limiting groove that matches the shape of the frame material plate, used to accommodate and position a single frame material plate. When the picking cylinder 403 drives the two picking clamps 404 to move in opposite directions, the limiting groove opens, releasing the frame material plate.

[0077] Specifically, the material picking drive assembly includes a material picking drive 406. In this embodiment, the material picking drive 406 is preferably an electric slide table. The drive end of the material picking drive 406 is fixedly connected to the material picking slider 402. The material picking drive 406 can drive the material picking slider 402 to move axially along the material picking guide rail 401, thereby driving the material picking clamp 404 and the picture frame material plate on it to move from below the material rack 202 to the shaping seat 204 of the placement bracket 201, and placing the picture frame material plate in the shaping seat 204.

[0078] In the initial state, the receiving seat 501 is located directly below the pre-compression assembly, the piston rod of the material-supporting cylinder 302 extends, and the material-supporting plate 301 only supports the mirror frame material plate in the other side receiving cavity 203. The material-taking clamping plate 404 is located directly below the receiving cavity 203 on the side of the material rack 202 closest to the material-taking unit 400. The lowest mirror frame material plate in this side receiving cavity 203 is placed into the limiting groove between the two material-taking clamping plates 404 under the action of gravity. Then, the material-taking drive unit 406 is activated, driving the material-taking slider 402 to move and transport the mirror frame material plate to the shaping seat 204. After it is in place, the material-taking cylinder 403 drives the two material-taking clamping plates 404 to separate, and the mirror frame material plate detaches from the material-taking clamping plates 404 and falls onto the shaping seat 204. The shaping assembly works with the shaping seat 204 to perform shaping processing on the mirror frame material plate. Next, the two pick-up clamps 404 re-clamp the frame plate and move it above the receiving seat 501, placing the frame plate into the receiving seat 501. Then, the pick-up drive 406 reverses its direction, causing the pick-up slider 402 and the pick-up clamps 404 to return to their original positions. The two pick-up clamps 404 move towards each other and close, re-forming the limiting groove, ready for the next pick-up.

[0079] Simultaneously or slightly earlier as the material handling unit 400 moves, the piston rod of the material supporting cylinder 302 begins to retract, driving the material supporting plate 301 to move towards the material handling unit 400. When the material handling clamp 404 has completely left the area below the material rack 202, the piston rod of the material supporting cylinder 302 has retracted into position, and the material supporting plate 301 moves back to below the two receiving cavities 203, simultaneously supporting the mirror frame material plates on both sides.

[0080] When the picking unit 400 moves toward the area below the material rack 202, the piston rod of the material support cylinder 302 begins to extend, driving the material support plate 301 to move away from the picking unit 400. When the picking unit 400 is located directly below the receiving cavity 203 on one side of the material rack 202, when the piston rod extends to its limit position, the material support plate 301 only supports the frame material plate of the receiving cavity 203 on the other side.

[0081] The receiving unit 500 is located at the end of the workbench 100 opposite to the picking unit 400, such as... Figure 6 As shown, the receiving unit includes a receiving base 501, a receiving drive assembly, and a guide assembly.

[0082] Specifically, the upper surface of the receiving base 501 is provided with a bending groove 502 for accommodating the frame material plate, the shape of which matches the final bending shape of the frame material plate. The lower end of the receiving base 501 is connected to the guide assembly.

[0083] Specifically, the guiding assembly includes guide rails 503 and guide sliders 504. The two guide rails 503 are fixed parallel and symmetrically on the worktable 100. One end of the guide slider 504 is slidably engaged with the guide rails 503, and the other end is fixedly connected to the receiving seat 501.

[0084] Specifically, the receiving drive assembly includes a receiving drive component 505. In this embodiment, the receiving drive component 505 is preferably an electric slide. The drive end of the receiving drive component 505 is fixedly connected to the receiving seat 501, and the receiving drive component 505 can drive the receiving seat 501 to move axially along the guide rail 503.

[0085] In use, the frame material is placed into the bending groove 502 for positioning. Then, the receiving drive 505 drives the receiving seat 501 to move directly below the bending unit 600, awaiting bending processing. After processing is completed, the receiving drive 505 moves the receiving seat 501 to the transport position so that the transport unit 700 can take away the finished product.

[0086] The bending unit 600 is located at the end of the workbench 100 opposite to the material handling unit 400, such as... Figure 7 and Figure 8 As shown, the bending unit includes a bending support 601, a shaping component, a pre-compression component, a bending component, and an ejector component.

[0087] Specifically, the bending bracket 601 spans across the receiving unit 500 and is installed on the upper surface of the workbench 100.

[0088] Specifically, the shaping assembly is located at one end of the bending bracket 601 near the material receiving unit 400 and above the shaping seat 204. It includes a shaping cylinder 602, a connecting block 603, and a shaping plate 604. The piston rod of the shaping cylinder 602 is connected to the upper end face of the shaping plate 604 via the connecting block 603. The shaping cylinder 602 drives the shaping plate 604 to reciprocate vertically, performing surface shaping treatment before the frame material enters the receiving unit 500. In use, the lower surface of the shaping plate 604 and the upper surface of the shaping seat 204 together apply uniform pressure to the frame material sandwiched therebetween. This eliminates local warping or irregularity of the frame material caused by transportation or stacking, ensuring subsequent bending accuracy.

[0089] Specifically, a pre-compression assembly is located at one end of the bending support 601 near the material receiving unit 400. It includes a pre-compression cylinder 605 and a pre-compression block 606. The piston rod of the pre-compression cylinder 605 is connected to the upper end face of the pre-compression block 606. The pre-compression cylinder 605 drives the pre-compression block 606 to reciprocate vertically. The lower end face of the pre-compression block 606 has an arc-shaped pre-compression section. The pre-compression section cooperates with the bending groove 502 of the receiving seat 501 to pre-compress the mirror frame material.

[0090] Specifically, the material-ejecting assembly includes an ejector cylinder 609 and an ejector rod 610. The ejector cylinder 609 is mounted on the receiving seat 501. The ejector rod 610 is arranged vertically, with its lower end connected to the piston rod of the ejector cylinder 609, and its upper end passing through the bottom of the receiving seat 501 and extending to the bottom area of ​​the bending groove 502. When the ejector rod 610 is in the retracted state, the upper end surface of the ejector rod 610 is flush with or slightly lower than the bottom surface of the bending groove 502 to avoid interfering with the bending and positioning of the frame material.

[0091] In use, the receiving seat 501 moves directly below the pre-pressing component, and the bending groove 502 of the receiving seat 501 is vertically aligned with the arc-shaped pre-pressing part at the lower end of the pre-pressing block 606. At this time, the receiving drive component temporarily stops driving to wait for the pre-pressing process to be completed. The pre-pressing cylinder 605 starts, pushing the pre-pressing block 606 downward. The pre-pressing part of the pre-pressing block 606 first contacts the mirror frame material plate. As the cylinder stroke advances, it gradually presses the mirror frame material plate into the bending groove 502, causing the mirror frame material plate to undergo an initial arc-shaped bend. After the pre-pressing is in place, the pre-pressing cylinder 605 resets, and the pre-pressing block 606 is lifted.

[0092] Specifically, the bending assembly is disposed on the bending bracket 601, which includes a bending cylinder 607 and a bending block 608. The piston rod of the bending cylinder 607 is connected to the upper end face of the bending block 608, and the bending cylinder 607 is used to drive the bending block 608 to reciprocate in the vertical direction. The lower end face of the bending block 608 has an arc-shaped bending portion, the curvature of which is greater than that of the pre-pressing block 606. The bending portion is used to cooperate with the bending groove 502 of the receiving seat 501 to perform bending treatment on the mirror frame material.

[0093] In use, the receiving seat 501 moves directly below the bending assembly, and the bending groove 502 of the receiving seat 501 is precisely aligned vertically with the arc-shaped bending part at the lower end of the bending block 608. At this time, the receiving drive assembly temporarily stops driving to wait for the bending process to be completed. The bending cylinder 607 drives the bending block 608 downward, and the bending part completely presses the pre-pressed frame material plate against the bottom of the bending groove 502. At this time, the convex arc surface of the bending part is completely in contact with the concave arc surface of the bending groove 502, and the frame material plate is clamped and forced to deform to the final preset bending shape.

[0094] After the frame material is bent by the pre-pressing and bending components, the piston rod of the ejector cylinder 609 extends upward, driving the ejector rod 610 to rise. This lifts the finished frame material in the bending groove 502, causing part of the frame material to disengage from the bending groove 502, making it easier for the handling unit 700 to grab and remove the finished product from above. After ejection is complete, the piston rod of the ejector cylinder 609 retracts, and the ejector rod 610 resets, ready for the next ejection cycle.

[0095] The conveying unit 700 is used to remove the bent frame material from the receiving seat 501 and transfer it to the storage position. It includes a conveying bracket 701, a moving component, a driving component, a lifting component, a clamping component, and a storage box 707.

[0096] Specifically, the transport bracket 701 is located at the end of the bending bracket 601 away from the pre-compression component and above the receiving unit 500.

[0097] like Figure 9 As shown, specifically, the moving component includes a moving guide rail 702 and a moving seat 703. The two moving guide rails 702 are symmetrically arranged on one side of the transport bracket 701. A moving slider is slidably arranged on the moving guide rail 702. The moving seat 703 is slidably engaged with the two moving guide rails 702 through the moving slider. The moving seat 703 can move along the axial direction of the moving guide rail 702.

[0098] Specifically, the drive assembly includes a drive cylinder 704, which is located on one side of the transport bracket 701. Its piston rod is connected to the movable seat 703. When the piston rod of the drive cylinder 704 extends or retracts, it can drive the movable seat 703 to reciprocate linearly along the axial direction of the movable guide rail 702.

[0099] Specifically, the lifting assembly includes a lifting cylinder 705, which is located on one side of the movable seat 703 and can move synchronously with the movable seat 703. The piston rod of the lifting cylinder 705 is connected to the clamping assembly through a mounting plate and is used to drive the clamping assembly to lift.

[0100] Specifically, the clamping assembly includes a gripper cylinder 706, the upper end face of which is fixedly connected to the lower surface of the mounting plate. The gripper cylinder 706 is used to clamp and transport the frame material plate in the bending groove 502.

[0101] Specifically, the storage box 707 is a container with its opening facing upwards. The storage box 707 is located at one end of the workbench 100 near the conveying unit 700 and is used to store the frame material that has been bent.

[0102] After the bending process is completed, the receiving seat 501 moves directly below the conveying unit 700. The lifting cylinder 705 is activated, causing the gripper cylinder 706 to descend until its gripper ends are flush with the edges of the frame material in the bending groove 502. The gripper cylinder 706 then activates, closing the two grippers to clamp the edges of the frame material, thus gripping it. Next, the piston rod of the lifting cylinder 705 retracts upward, lifting the frame material and completely disengaging it from the bending groove 502 of the receiving seat 501. The drive cylinder 704 is activated, pushing the moving seat 703 along the moving guide rail 702 towards the storage box 707. When the moving seat 703 is directly above the storage box 707, the drive cylinder 704 stops. The lifting cylinder 705 restarts, causing the frame material plate to descend. Then, the grippers of the clamping cylinder 706 open, sending the frame material plate into the storage box 707. After the material is unloaded, the lifting cylinder 705 resets, the drive cylinder 704 resets, and the moving seat 703 and clamping assembly return to their original positions, awaiting the start of the next handling cycle.

[0103] The method of using this invention specifically includes the following steps:

[0104] Material handling steps: Control the material support cylinder 302 so that the material support plate 301 only supports the receiving cavity 203 on one side of the material rack 202, and the bottom frame material plate in the receiving cavity 203 on the other side is placed into the limiting groove of the material handling clamp 404 under the action of gravity.

[0105] Shaping step: The material picking drive 406 drives the material picking unit 400 to transport the clamped frame material plate to the shaping seat 204. The material picking clamp 404 releases the frame material plate, and the shaping component performs shaping processing on the frame material plate on the shaping seat 204.

[0106] Material receiving steps: The material receiving drive unit 505 drives the material receiving seat 501 to move below the pre-compression component, the material picking clamp 404 re-clamps the shaped mirror frame material plate, and the material picking drive unit 406 conveys it to the bending groove 502 above the material receiving seat 501 and releases it, so that the mirror frame material is placed into the bending groove 502.

[0107] Bending steps: The pre-pressing unit pre-presses the frame material, the receiving drive 505 drives the receiving seat 501 to move below the bending assembly, and the bending unit 600 performs the final bending of the frame material.

[0108] Material lifting step: After bending is completed, the material lifting cylinder 609 drives the material lifting rod 610 to rise, lifting the finished mirror frame material plate in the bending groove 502 upward, so that part of the mirror frame material plate is removed from the bending groove 502, making it easier for the handling unit 700 to grab it.

[0109] Handling steps: After the top material is completed, the receiving drive 505 drives the receiving seat 501 to move below the handling unit 700, and the clamping component grabs the bent mirror frame material and transfers it to the storage box 707.

[0110] During the receiving step, when the material taking unit 400 returns to its original position, the piston rod of the material supporting cylinder 302 retracts, driving the material supporting plate 301 to move below the two receiving cavities 203; when the material taking unit 400 moves again below the material rack 202, the material supporting cylinder 302 drives the material supporting plate 301 to move away from the material taking unit 400 in order to release the next frame material plate.

[0111] It also includes a rotating material changing step: after all the mirror frame plates in the receiving cavity 203 on one side of the material rack 202 have been taken out, the rotating component drives the material rack 202 to rotate, and rotates the receiving cavity 203 on the other side to above the material taking unit 400 to achieve continuous material taking.

[0112] During the shaping process, the shaping component drives the shaping plate 604 downward through the shaping cylinder 602, and together with the upper surface of the shaping seat 204, applies uniform pressure to the frame material to eliminate warping or irregularity.

[0113] In the bending step, the pre-pressing block 606 of the pre-pressing component first presses the frame material into the bending groove 502 to form an arc-shaped bend, and then the bending block 608 of the bending component completely presses the frame material into the final preset bending shape.

[0114] During the handling process, the clamping component drives the gripper cylinder 706 to descend via the lifting cylinder 705. The grippers of the gripper cylinder 706 close and grab the two sides of the frame material plate. After being lifted, it is moved above the storage box 707 by the drive cylinder 704 and released.

[0115] In summary, this invention realizes an automated processing flow for the picking, bending, and handling of eyeglass frame panels, which is suitable for the mass production needs of the eyewear manufacturing industry.
