Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a feeding device. Background Technology

[0002] To create permanent marks on the surface of a workpiece, laser marking is required. Before marking, a carrier holding multiple workpieces is placed inside a fixture. The fixture is then flipped and placed onto a positioning element in the marking machine. The marking machine marks the workpieces inside the fixture through holes in the fixture's base. The fixture's cover and base are engaged by a clamping handle; this handle needs to be opened or closed when changing the carrier within the fixture. Currently, the carrier and workpieces are manually changed before the fixture is placed on the positioning element, resulting in low work efficiency. Utility Model Content

[0003] In view of this, this application provides a feeding device to solve the problem of low material changing efficiency when marking workpieces.

[0004] This application provides a feeding device, the feeding device comprising: A machine base, on which a support is mounted; A flipping module is mounted on the bracket and carries a fixture. The fixture is used to mount a carrier holding a workpiece to be processed. The flipping module flips relative to the bracket and drives the fixture to flip together. A disassembly / assembly module is positioned vertically above the flip module and connected to the bracket; the disassembly / assembly module moves toward the flip module to assemble or disassemble the fixture on the flip module; The transfer module and the material changing module are located on opposite sides of the flipping module. The transfer module transfers the fixture after it has been flipped by the flipping module, and the material changing module places the carrier containing the workpiece to be processed onto the fixture on the flipping module. The flipping module includes a first rotating component and a carrier component. The first rotating component is rotatably mounted on the bracket, and the carrier component is mounted on the first rotating component. The carrier component carries the fixture and drives the fixture to rotate with the first rotating component. The carrier component and the first rotating component are eccentrically arranged. When the flipping module is in the initial state, the straight line of the central axis of the carrier component is located below the straight line of the rotation center of the first rotating component.

[0005] In one possible embodiment, the carrier includes a receiving hole and a limiting protrusion, the limiting protrusion protruding from the sidewall of the receiving hole, and the receiving hole having grooves on both sides; the flipping module includes two limiting components symmetrically arranged on both sides of the receiving hole along the extending direction of the carrier, the limiting component including a limiting block and a limiting cylinder, the limiting cylinder being mounted on the carrier, the limiting block being located in the groove and connected to the output end of the limiting cylinder, the limiting cylinder driving the limiting block to move towards or away from the receiving hole, the limiting block cooperating with the limiting protrusion to fix the fixture to the carrier; when the flipping module is in the initial state, the limiting protrusion is located on the side of the receiving hole away from the machine tool, and the limiting block is located on the side of the receiving hole closer to the machine tool.

[0006] In one possible embodiment, the transfer module is provided with transfer trays on both sides near and away from the flipping module. The transfer trays transfer the fixture after it has been flipped by the flipping module. The carrier includes a clearance opening that communicates with the receiving hole. When the flipping module is in the flipped state, the clearance opening is located on the side of the carrier near the transfer module, and the transfer tray passes through the receiving hole in a direction that is close to or away from the machine tool.

[0007] In one possible embodiment, the transfer module includes a first lifting cylinder and a second rotating component. The first lifting cylinder extends in a direction perpendicular to the machine base, and the transfer plate is mounted on the first lifting cylinder. The rotation axis of the second rotating component is perpendicular to the machine base, and the first lifting cylinder is mounted on the second rotating component.

[0008] In one possible embodiment, the flipping module includes two fastening components, which are correspondingly disposed with respect to the two limiting components. The two fastening components are located above the corresponding limiting components and connected to the carrier. The two fastening components are movable in a direction close to or away from the receiving hole to assemble the fixture on the carrier.

[0009] In one possible embodiment, the fastening assembly includes a first push block, a fastening cylinder, and a cylinder bracket. The fastening cylinder is located above the limiting cylinder and is mounted on the carrier via the cylinder bracket. The first push block is mounted on the output end of the fastening cylinder, and the fastening cylinder drives the first push block to move in a direction closer to or further away from the receiving hole.

[0010] In one possible embodiment, the disassembly module includes a disassembly assembly disposed above the carrier and moving towards or away from the fastening assembly. The disassembly assembly includes a disassembly cylinder and two second push blocks symmetrically mounted at the output end of the disassembly cylinder, and corresponding to the two fastening assemblies. Along an extension direction parallel to the carrier, the disassembly cylinder drives the second push blocks to move towards or away from the fastening assemblies in a direction parallel to the extension direction of the carrier, thereby disassembling the fixture on the carrier.

[0011] In one possible embodiment, the disassembly module includes a cover plate removal assembly, which includes a cover plate removal cylinder and at least two cover plate removal grippers. The cover plate removal cylinder and the disassembly cylinder are arranged in a cross shape. At least two of the cover plate removal grippers are mounted on the cover plate removal cylinder. The cover plate removal cylinder drives the at least two cover plate removal grippers to move closer to or further away from each other in a direction perpendicular to the extension direction of the carrier, so that the at least two cover plate removal grippers place the cover plate on the fixture on the carrier, or so that the at least two cover plate removal grippers grasp the cover plate on the fixture after it has been disassembled by the disassembly assembly.

[0012] In one possible embodiment, the disassembly module includes a second lifting cylinder mounted on the bracket and extending away from the flipping module. The disassembly assembly and the cover plate assembly are movably mounted on the second lifting cylinder, which drives the disassembly assembly and the cover plate assembly to move closer to or away from the flipping module.

[0013] In one possible embodiment, the feeding device includes a feeding tray, and the material changing module includes a pick-and-place component that moves between the feeding tray and the flipping module; the pick-and-place component includes a mounting plate, a feeding component, and a discharging component, with the feeding component and the discharging component spaced apart from each other on the mounting plate.

[0014] The material changing module can transfer unmarked workpieces to the flipping module. A disassembly / assembly module is located above the flipping module. The flipping module carries a fixture, which is used to mount a carrier containing the workpiece to be processed. The fixture is fixed to the flipping module, and then the flipping module rotates the fixture. The transfer module can transfer the flipped fixture from the flipping module to the positioning device of the marking machine. The flipping module includes a first rotating component and a carrier component. The first rotating component is rotatably mounted on a bracket, and the carrier component is mounted on the first rotating component, allowing the carrier component to rotate with the first rotating component. The first rotating component and the carrier component are eccentrically positioned. When the flipping module is in its initial state, the line containing the central axis of the carrier component is located below the line containing the rotation center of the first rotating component. This increases the distance between the flipping module and the disassembly / assembly module and reduces the distance between the carrier component and the material changing module, facilitating the material changing module to place the fixture onto the carrier component.

Detailed Implementation

[0018] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the marking machine 100 can form permanent marks on the surface of a workpiece using a laser. When marking the workpiece surface, the workpiece is first placed on the carrier 200, then the carrier 200 is fixed inside the fixture 300, then the fixture 300 is placed on the positioning device 101 inside the marking machine 100, and finally the marking device 102 located above the positioning device 101 marks the workpiece surface.

[0020] like Figure 1 As shown, the fixture 300 includes a base 301 and a cover plate 302, with the carrier 200 located between the base 301 and the cover plate 302. Handles 303 are provided on opposite sides of the base 301, and are rotatably mounted on the base 301. The cover plate 302 is detachably fastened to the side of the base plate where the handles 303 are located. A locking structure is provided on the side of the handle 303 away from the base 301, allowing the handle 303 to engage with the edge of the cover plate 302. After the cover plate 302 is placed on the base 301, the two handles 303 on the base 301 rotate towards each other, and the locking structure on the handles 303 engages with the edge of the cover plate 302, thus limiting the relative position of the cover plate 302 and the base 301 and reducing the possibility of the carrier 200 falling between the cover plate 302 and the base 301. When the two handles 303 on the base 301 are rotated in a direction away from each other, the engagement between the handles 303 and the edge of the cover plate 302 can be released, allowing the cover plate 302 to be detached from the base 301, so as to facilitate the replacement of the carrier 200 between the base 301 and the cover plate 302.

[0021] The base 301 is provided with a through hole 3011. The position on the workpiece that needs to be marked is aligned with the through hole 3011. Before placing the fixture 300 in front of the positioning device 101, the fixture 300 needs to be flipped so that the base 301 faces the marking device 102 so that the laser can irradiate the position on the workpiece that needs to be marked through the through hole 3011.

[0022] like Figure 2 and Figure 3As shown, this application embodiment provides a feeding device, including a machine base 1, a tilting module 2, a disassembly and assembly module 3, a transfer module 4, and a material changing module 5. A bracket 11 is installed on the machine base 1. The tilting module 2 and the disassembly and assembly module 3 are both installed on the bracket 11, and the disassembly and assembly module 3 is located above the tilting module 2. The transfer module 4 and the material changing module 5 are located on both sides of the tilting module 2.

[0023] A loading tray 6 is located on the side of the material changing module 5 away from the flipping module 2. Multiple carriers 200 are placed inside the loading tray 6, and multiple unmarked workpieces are placed inside each carrier 200. The material changing module 5 can transfer the carriers 200 containing the unmarked workpieces to the flipping module 2. A base 301 for a fixture 300 is placed inside the flipping module 2, and the carriers 200 are placed on the base 301. A disassembly / assembly module 3 is located on the side of the flipping module 2 away from the machine tool 1. After the carriers 200 are placed on the base 301, the disassembly / assembly module 3 can fasten the cover plate 302 onto the base 301. The flipping module 2 can then drive the handle 303 to engage with the cover plate 302, and then the flipping module 2 rotates the fixture 300 180°. The marking machine 100 is located on the side of the transfer module 4 away from the flipping module 2. The transfer module 4 can transfer the flipped fixture 300 from the flipping module 2 to the positioning device 101 of the marking machine 100.

[0024] like Figure 3 and Figure 4 As shown, the flipping module 2 includes a first rotating component 21 and a supporting component 22. The first rotating component 21 is rotatably mounted on the bracket 11, and the supporting component 22 is mounted on the first rotating component 21, allowing the supporting component 22 to rotate with the first rotating component 21. The first rotating component 21 and the supporting component 22 are eccentrically positioned, so that when the flipping module 2 is in its initial state, the line containing the central axis of the supporting component 22 is located below the line containing the rotation center of the first rotating component 21.

[0025] When the flipping module 2 is in its initial state, the material changing module 5 places the carrier 200 on the base 301 on the flipping module 2. At this time, the base 301 is located on the side of the flipping module 2 facing the disassembly module 3. The first rotating component 21 and the carrier component 22 are eccentrically positioned, which increases the distance between the flipping module 2 and the disassembly module 3 and reduces the distance between the carrier component 22 and the material changing module 5, making it easier for the material changing module 5 to place the carrier 200 on the base 301.

[0026] like Figure 4 and Figure 5As shown, in one possible embodiment, the support member 22 includes a base 301 of the fixture 300 placed within the receiving hole 221. The support member 22 also includes a limiting protrusion 222 protruding from the side wall of the receiving hole 221. Fixing blocks 304 are provided on both sides of the base 301, and when the base 301 is placed in the receiving hole 221, one side of the fixing block 304 abuts against the limiting protrusion 222. The flipping module 2 includes two limiting components 23 symmetrically arranged on both sides of the receiving hole 221 along the extension direction of the carrier 22. Each limiting component 23 includes a limiting block 231 and a limiting cylinder 232. The receiving hole 221 of the carrier 22 is provided with a sliding groove 233 on both sides. The limiting cylinder 232 is installed on the carrier 22. The limiting block 231 is slidably disposed in the sliding groove 233 and the limiting block 231 is connected to the output end of the limiting cylinder 232, so that the limiting cylinder 232 can push the limiting block 231 to move in a direction closer to or away from the receiving hole 221.

[0027] After the limiting block 231 moves toward the receiving hole 221, along the thickness direction of the base 301, the limiting block 231 and the limiting protrusion 222 are located on both sides of the fixing block 304, so that the base 301 is fixed to the carrier 22, which can reduce the possibility of the base 301 falling off when the carrier 22 is flipped.

[0028] like Figure 4 As shown, when the flipping module 2 is in the initial state, the limiting protrusion 222 is located on the side of the receiving hole 221 away from the machine tool 1, the limiting block 231 is located on the side of the receiving hole 221 close to the machine tool 1, and the limiting protrusion 222 and the limiting block 231 clamp the base 301.

[0029] After the carrier 22 rotates the fixture 300, the limiting block 231 is located on the side of the receiving hole 221 away from the machine tool 1. After rotation, the limiting cylinder 232 drives the limiting block 231 to move away from the receiving hole 221, releasing the contact between the limiting block 231 and the fixing block 304, allowing the fixture 300 to be removed and detached from the carrier 22. At this time, the transfer module 4 can lift the fixture 300, causing the fixture 300 to detach from the carrier 22.

[0030] like Figure 4 As shown, in one possible embodiment, the flipping module 2 includes two fastening components 24, which are correspondingly arranged with two limiting components 23 and are positioned above the corresponding limiting components 23. The two fastening components 24 can move in a direction close to or away from the receiving hole 221. When the two fastening components 24 move in a direction close to the receiving hole 221, they can push the handles 303 on both sides of the cover plate 302 to rotate in a direction close to each other, so that the handles 303 can engage with the edge of the cover plate 302 to fix the cover plate 302 to the base 301.

[0031] Each fastening assembly 24 includes a first push block 241, a fastening cylinder 242, and a cylinder bracket 243. The fastening cylinder 242 is located above the limiting cylinder 232 and is mounted on the carrier 22 via the cylinder bracket 243. The first push block 241 is mounted on the output end of the fastening cylinder 242, and the fastening cylinder 242 can push the first push block 241 to move closer to or further away from the receiving hole 221. The positions of the fastening cylinder 242 and the first push block 241 correspond to the positions of the handle 303 on the base 301. When the base 301 is placed in the receiving hole 221, the first push block 241 is located on the side of the handle 303 away from the base 301. When the first push block 241 moves toward the receiving hole 221, it can push the handles 303 on both sides of the cover plate 302 to rotate toward each other, so that the handles 303 can engage with the edge of the cover plate 302 to fix the cover plate 302 to the base 301. When the first push block 241 moves away from the receiving hole 221, there is a gap between the first push block 241 and the handles 303, so that the handles 303 on both sides of the cover plate 302 can move away from each other to release the engagement between the handles 303 and the cover plate 302.

[0032] like Figure 6 As shown, in one possible embodiment, the disassembly module 3 includes a disassembly component 31, which is located above the support member 22 and is capable of moving in a direction close to or away from the support member 22.

[0033] The disassembly assembly 31 includes two second push blocks 311 and a disassembly cylinder 312. The two second push blocks 311 are symmetrically mounted on the output end of the disassembly cylinder 312 and are correspondingly arranged with the two fastening assemblies 24, so that the disassembly cylinder 312 can push the two second push blocks 311 to move closer to or away from the corresponding fastening assembly 24 in a direction parallel to the extension direction of the carrier 22. When the first push block 241 of the two fastening assemblies 24 moves away from the receiving hole 221, the disassembly cylinder 312 pushes the two second push blocks 311 to move closer to the fastening assembly 24, so that the two second push blocks 311 abut against the corresponding handle 303, and pushes the handles 303 on both sides of the cover plate 302 to move away from each other, so that the handles 303 are disengaged from the cover plate 302. When the disassembly cylinder 312 drives the two second push blocks 311 to move away from the fastening assembly 24, the first push block 241 can move closer to the receiving hole 221, pushing the handle 303 to fasten with the cover plate 302.

[0034] like Figure 6 As shown, in one possible embodiment, the disassembly module 3 further includes a cover plate removal assembly 32, which is located above the support member 22 and can move in a direction close to or away from the support member 22.

[0035] The cover plate removal assembly 32 includes at least two cover plate removal jaws 321 and a cover plate removal cylinder 322. The at least two cover plate removal jaws 321 are connected to both ends of the cover plate removal cylinder 322. The cover plate removal cylinder 322 and the disassembly cylinder 312 are arranged in a cross shape, and the disassembly cylinder 312 is located between the at least two cover plate removal jaws 321. The cover plate removal cylinder 322 can drive the at least two cover plate removal jaws 321 to move closer to or further away from each other in a direction perpendicular to the extension direction of the carrier 22. The movement direction of the at least two cover plate removal jaws 321 is perpendicular to the movement direction of the two second push blocks 311.

[0036] When at least two cover plate grippers 321 move toward each other, they can clamp the cover plate 302; when at least two cover plate grippers 321 move away from each other, they can release the cover plate 302. After the second push block 311 pushes the handle 303 to disengage from the cover plate 302, the at least two cover plate grippers 321 move toward each other, clamping the cover plate 302 and removing it from the base 301, so as to facilitate the replacement of the carrier 200 and the workpiece in the fixture 300.

[0037] like Figure 6 As shown, in one possible embodiment, the disassembly module 3 includes a second lifting cylinder 33, which is located on the side of the flipping module 2 away from the machine base 1 and is mounted on the bracket 11.

[0038] The cover plate assembly 32 is connected to the second lifting cylinder 33. The second lifting cylinder 33 can drive the disassembly assembly 31 and the cover plate assembly 32 to move in the direction of approaching or moving away from the flipping module 2, so that the disassembly assembly 31 can release the handle 303 from the cover plate 302, the cover plate assembly 32 can clamp the cover plate 302, and can drive the cover plate 302 to move in the direction of approaching or moving away from the base 301.

[0039] like Figure 3 and Figure 7 As shown, in one possible embodiment, the transfer module 4 is located between the positioning device 101 and the flipping module 2. Transfer disks 41 are provided on both sides of the transfer module 4, near and away from the flipping module 2. A jig 300 on the carrier 22 holds multiple unprocessed workpieces. The transfer disk 41 on the side near the flipping module 2 can transfer the jig 300 on the carrier 22 to the positioning device 101, so that the marking device 102 can mark the workpiece surface. After marking, the workpiece is located in the jig 300 on the positioning device 101. The transfer disk 41 on the side near the positioning device 101 can transfer the carrier 200 on the positioning device 101 to the flipping module 2, so that the workpiece can be removed from the jig 300.

[0040] like Figure 7As shown, in one possible embodiment, the transfer module 4 includes a first lifting cylinder 42 that extends in a direction perpendicular to the machine tool 1, and a transfer plate 41 is mounted on the first lifting cylinder 42 so that the transfer plate 41 can move in a direction perpendicular to the machine tool 1.

[0041] When the transfer module 4 is in its initial state, the transfer disk 41 on the side closer to the flipping module 2 is located on the side of the carrier 22 closest to the machine platform 1, and the transfer disk 41 on the side closer to the positioning device 101 is located on the side of the positioning device 101 facing the machine platform 1. Driven by the first lifting cylinder 42, the transfer disk 41 moves away from the machine platform 1. The transfer disk 41 on the side closer to the flipping module 2 can lift the jig 300 on the carrier 22, causing the jig 300 to detach from the carrier 22, and the transfer disk 41 on the side closer to the positioning device 101 can lift the jig 300 on the positioning device 101, causing the jig 300 to detach from the positioning device 101. When the transfer plate 41 moves toward the machine platform 1 under the drive of the first lifting cylinder 42, the transfer plate 41 on the side closer to the flipping module 2 can place the jig 300 it is supporting into the receiving hole 221 of the carrier 22, and the transfer plate 41 on the side closer to the positioning device 101 can place the jig 300 it is supporting onto the positioning device 101.

[0042] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in one possible embodiment, the carrier 22 includes a clearance opening 223 that communicates with the receiving hole 221. When the flipping module 2 is in the flipped state, the clearance opening 223 is located on the side of the carrier 22 closer to the transfer module 4, so that the transfer disk 41 in the transfer module 4 can pass through the receiving hole 221.

[0043] When the transfer tray 41 moves away from the machine tool 1 to lift the fixture 300 in the receiving hole 221, or when the transfer tray 41 moves towards the machine tool 1 to place the fixture 300 in the receiving hole 221, the transfer tray 41 needs to pass through the receiving hole 221. The transfer tray 41 is mounted on the first lifting cylinder 42, and the first lifting cylinder 42 is located on the side of the flipping module 2 near the positioning device 101. An avoidance opening 223 is provided only on one side of the receiving hole 221, which can reduce the possibility of interference between the transfer tray 41 and the carrier 22, and at the same time improve the load-bearing capacity of the carrier 22.

[0044] like Figure 1 and Figure 8As shown, in one possible embodiment, the positioning device 101 includes a plurality of support columns 1011. When the transfer disk 41 moves towards the machine platform 1 under the drive of the first lifting cylinder 42, it can move between adjacent support columns 1011, so that the support columns 1011 support the fixture 300. The support column 1011 includes a recess 1012. When the transfer disk 41 moves between adjacent support columns 1011 under the drive of the first lifting cylinder 42, the fixture 300 is located in the recess 1012 to limit the relative position between the fixture 300 and the support column 1011. Positioning columns 1013 are provided between the plurality of support columns 1011. The cover plate 302 of the fixture 300 is provided with positioning holes 3021. When the fixture 300 is placed on the support column 1011, at least a portion of the positioning column 1013 extends into the positioning hole 3021, which can determine the position of the fixture 300 in the positioning device 101 and also play a foolproof role.

[0045] like Figure 7 As shown, in one possible embodiment, the transfer module 4 includes a second rotating member 43, and a first lifting cylinder 42 is mounted on the second rotating member 43. The rotation axis of the second rotating member 43 is perpendicular to the machine base 1, so that the transfer tray 41 can rotate between the flipping module 2 and the positioning device 101 with the first lifting cylinder 42.

[0046] Driven by the first lifting cylinder 42, the transfer tray 41 moves away from the machine base 1, lifting the fixture 300 on the carrier 22 and the positioning device 101. Then, the second rotating component 43 drives the first lifting cylinder 42 to rotate, causing the positions of the two transfer trays 41 to be exchanged. Then, driven by the first lifting cylinder 42, the transfer tray 41 moves closer to the machine base 1, placing the fixture 300 on the transfer tray 41 onto the carrier 22 and the positioning device 101 to replace the workpiece before and after marking.

[0047] like Figure 1 and Figure 7 As shown, in one possible embodiment, the cover plate 302 of the fixture 300 is provided with a positioning groove 3022 on its side, and the transfer plate 41 includes a positioning protrusion 411. After the transfer plate 41 supports the fixture 300, the positioning protrusion 411 is located in the positioning groove 3022, which restricts the relative position between the transfer plate 41 and the fixture 300, and can also reduce the possibility of the fixture 300 slipping off the transfer plate 41, thereby improving the stability of the transfer of the fixture 300.

[0048] like Figure 3 and Figure 9As shown, in one possible embodiment, the material changing module 5 includes a pick-and-place assembly 51 and a robotic arm 52. The robotic arm 52 is located between the loading tray 6 and the flipping module 2. The pick-and-place assembly 51 is mounted on the robotic arm 52, and the robotic arm 52 can drive the pick-and-place assembly 51 to move between the loading tray 6 and the flipping module 2. The pick-and-place assembly 51 includes a mounting plate 511, a loading component 512, and a unloading component 513. The mounting plate 511 is mounted on the robotic arm 52, and the loading component 512 and the unloading component 513 are spaced apart from each other on the mounting plate 511.

[0049] like Figure 10 As shown, the loading component 512 is used to place the carrier 200 in the loading tray 6 onto the flipping module 2. The loading component 512 includes two loading jaws 512a arranged opposite each other. The two loading jaws 512a are mounted on a cylinder, allowing them to move towards or away from each other. When the pick-and-place assembly 51 is above the loading tray 6, the loading jaws 512a are aligned with the carrier 200 in the loading tray 6, and the two loading jaws 512a move towards each other to grip the carrier 200 in the loading tray 6. When the pick-and-place assembly 51 is above the flipping module 2, the loading jaws 512a are aligned with the base 301 of the fixture 300 on the carrier 22, enabling the carrier 200 containing unprocessed workpieces to be placed on the base 301.

[0050] The unloading component 513 is used to remove the carrier 200 from the flipping module 2. The unloading component 513 includes two unloading jaws 513a arranged opposite each other. The two unloading jaws 513a are mounted on a cylinder, allowing the two unloading jaws 513a to move towards or away from each other. When the pick-and-place assembly 51 is located above the flipping module 2, the unloading component 513 aligns with the base 301 of the fixture 300 on the carrier 22 and clamps the carrier 200 in the base 301, causing the processed workpiece to detach from the base 301. Then, the loading component 512 is aligned with the base 301, and the carrier 200 containing the unprocessed workpiece is placed on the base 301.

[0051] like Figure 9 and Figure 10 As shown, in one possible embodiment, the material changing module 5 includes a connecting plate 514, which is fixed to one side of the mounting plate 511, allowing the mounting plate 511 to be connected to the robotic arm 52 via the connecting plate 514. A reinforcing rib 515 is provided at the connection between the connecting plate 514 and the mounting plate 511 to improve the connection strength between them and enhance the reliability of the material changing module 5.

[0052] The process of transferring unprocessed workpieces from the loading tray 6 to the marking machine 100 using the feeding device provided in this application embodiment is as follows: The loading component 512 clamps the carrier 200 containing the unprocessed workpieces on the loading tray 6, and the robotic arm 52 aligns the loading component 512 with the base 301 of the fixture 300 on the carrier component 22, and places the carrier 200 on the base 301 of the fixture 300; the disassembly component 31 and the cover plate removal component 32 in the disassembly and assembly module 3 move towards the flipping module 2 under the drive of the second lifting cylinder 33, so that the cover plate 302 is fastened to the base 301; the first push block 241 in the two fastening components 24 moves towards each other, so that the handle 303 on the base 301 engages with the edge of the cover plate 302; the cover plate removal component 32 in the disassembly and assembly module 3 moves towards the base 301 under the drive of the second lifting cylinder 33. The first rotating component 21 drives the carrier component 22 to rotate, causing the fixture 300 on the carrier component 22 to rotate 180°; the limiting block 231 moves away from the receiving hole 221 to release the limiting block 231 from limiting the fixture 300; the transfer plate 41 moves away from the machine platform 1 under the drive of the first lifting cylinder 42, so that the transfer plate 41 on the side closer to the flipping module 2 lifts the fixture 300 in the receiving hole 221, so that the fixture 300 is located between the flipping module 2 and the disassembly module 3; the second rotating component 43 drives the first lifting cylinder 42 to drive the transfer plate 41 to rotate, and transfers the fixture 300 to the position device 101; the transfer plate 41 moves towards the machine platform 1 under the drive of the first lifting cylinder 42, and places the fixture 300 in the position device 101.

[0053] The process of transferring the processed workpiece from the marking machine 100 to the loading tray 6 using the feeding equipment provided in this application embodiment is as follows: After the marking machine 100 completes marking, during the loading process, the transfer tray 41 moves away from the machine base 1 under the drive of the first lifting cylinder 42. The transfer tray 41 located on the side close to the positioning device 101 can lift the fixture 300 on the positioning device 101. During the loading process, the second rotating component 43 drives the first lifting cylinder 42 to rotate the transfer tray 41, which can transfer the fixture 300 loaded with the processed material to the top of the flipping module 2. During the loading process, the transfer tray 41 moves towards the machine base 1 under the drive of the first lifting cylinder 42, which can place the fixture 300 loaded with the processed material into the receiving hole 221 of the carrier component 22. The limiting block 231 moves towards the receiving hole 221, so that the limiting block 231 and the limiting protrusion 222 can limit the relative position between the fixture 300 and the carrier component 22. The first rotating component 21 drives the carrier component 22 to rotate, causing the fixture 300 on the carrier component 22 to rotate 180°; the disassembly assembly 31 and the cover plate removal assembly 32 move towards the carrier component 22 under the drive of the second lifting cylinder 33; the two second push blocks 311 in the disassembly assembly 31 and the first push blocks 241 in the two fastening assemblies 24 all move away from each other, so that the second push blocks 311 can push the handle 303 to move away from each other, so that the handle 303 and the cover plate... 302 Release the latch; the cover plate assembly 32 clamps the cover plate 302, and then moves away from the flipping module 2 under the drive of the second lifting cylinder 33, so that the cover plate 302 is separated from the base 301; before the loading part 512 is aligned with the base 301 of the fixture 300 on the carrier 22 by the robotic arm 52 during the above loading process, the unloading part 513 is aligned with the base 301 of the fixture 300 on the carrier 22, so that the unloading part 513 takes out the carrier 200 loaded with the processed workpiece.
