Description

Technical Field

[0001] This application relates to the field of automation equipment, and more particularly to an automatic feeding device. Background Technology

[0002] In the SMT production process, manual unloading is currently used. The cover plate on top of the carrier is removed, and the circuit boards inside are manually removed after cutting and placed into a tray. The cover plate is then replaced with the carrier. During this process, operators are prone to damaging the circuit boards, resulting in product scrap. Furthermore, manual circuit board handling is inefficient and cannot meet the needs of mass production. Utility Model Content

[0056] Please refer to Figures 1 to 26This application discloses an automatic unloading device 100 for transporting a plurality of components 400 carried in a carrier 200 to a pallet. In this embodiment, the component 400 is a circuit board. Multiple circuit boards are integrated onto a large substrate in an optimized layout. This large substrate is then placed in an SMT (Surface Mount Technology) machine for soldering electronic components. A precision cutting device then cuts the substrate into individual, fully functional circuit boards. The cut substrates are placed in the carrier 200. The automatic unloading device 100 disclosed in this application automatically transports the cut individual, fully functional circuit boards to the pallet. Compared to the traditional manual handling of circuit boards, this method not only improves handling efficiency but also reduces the losses caused by manually separating circuit boards.

[0057] Please refer to Figures 1 to 3 The automatic feeding device 100 includes a conveying mechanism 1 and a handling mechanism 2. The conveying mechanism 1 is configured such that the conveying carrier 200 moves along the conveying direction of the conveying mechanism 1, and the handling mechanism 2 is disposed above the conveying mechanism 1. For ease of explanation, the following definitions are provided. Figure 1 As shown, the conveying mechanism 1 extends along a first direction D1-D1, the pallet is located on one side of the conveying mechanism 1 in a second direction D2-D2, and the handling mechanism 2 is positioned above the conveying mechanism 1 along a third direction D3-D3. The conveying mechanism 1 moves the carrier 200 along the first direction D1-D1 to below the handling mechanism 2, and the handling mechanism 2 handles the material 400 in the carrier 200 to the pallet along the second direction D2-D2. The first direction D1-D1, the second direction D2-D2, and the third direction D3-D3 are all perpendicular to each other. In other embodiments, the pallet can be located at any position of the handling mechanism 2 as needed, which is not limited here.

[0058] Please refer to Figures 1 to 3 as well as Figures 10 to 11The automatic unloading device 100 also includes a mounting plate 8, on which the conveying mechanism 1 and the handling mechanism 2 are fixedly mounted. The conveying mechanism 1 includes two tracks 11 extending along a first direction D1-D1, which are respectively disposed on the top of the mounting plate 8 along the first direction D1-D1 and spaced apart along a second direction D2-D2. Each track 11 has a first position 101 spaced apart in the first direction D1-D1 and a second position 102 located downstream of the first position 101. In the embodiment of this application, the handling mechanism 2 is located at the first position 101. Each of the two tracks 11 is provided with a plurality of motors 12 and a conveyor belt 13 connected to the motors 12. When the carrier 200 is placed on the two tracks 11, the motors 12 drive the carrier 200 to move along the first direction D1-D1 from the first position 101 to the second position 102 via the conveyor belt 13. The handling mechanism 2 includes a first moving module 21 and a first suction module 22 disposed at the drive end of the first moving module 21. The first moving module 21 drives the first suction module 22 to move along the second direction D2-D2. The first suction module 22 includes multiple first driving members 221 and multiple first suction components 222, which are connected one-to-one. The first driving members 221 are configured to drive the corresponding first suction component 222 to move up and down along the third direction D3-D3. The multiple first suction components 222 are configured to suction the material 400 and selectively release the material 400. For example, the first suction component 222 can selectively release the material 400 based on whether the material 400 is qualified, its color, appearance, or its different uses, thereby distinguishing the material 400. This not only improves the handling efficiency of the material 400 but also reduces damage to the material 400 caused by manual operation. In the embodiments of this application, the first driving member 221 can be a structure capable of linear motion, such as a cylinder, hydraulic cylinder, or electric cylinder.

[0059] Please refer to Figure 3Specifically, the conveying mechanism 2 also includes two first support columns 24, which are spaced apart on the mounting plate 8 along the second direction D2-D2, and two tracks 11 are disposed between the two first support columns 24. A first moving module 21 is disposed on top of the two first support columns 24. The first moving module 21 includes a horizontal moving mechanism 211 and a vertical moving mechanism 212. The horizontal moving mechanism 211 is disposed on top of the two first support columns 24, the vertical moving mechanism 212 is disposed at the drive end of the horizontal moving mechanism 211, and the first suction module 22 is disposed at the drive end of the vertical moving mechanism 212. The horizontal moving mechanism 211 drives the first suction module 22 to move along the second direction D2-D2, and the vertical moving mechanism 212 drives the first suction module 22 to move up and down along the third direction D3-D3. This allows the position of the first suction module 22 to be adjusted so that the first suction module 22 can accurately pick up the material 400 on the carrier 200, thereby improving the handling efficiency of the material 400.

[0060] Please refer to Figures 4 to 9 The conveying mechanism 2 further includes a second suction module 23, which is disposed at the drive end of the first moving module 21. In the embodiments of this application, the drive end of the vertical moving mechanism 212 is provided with a first connecting block 213 and a second connecting block 214 vertically disposed on the first connecting block 213. The first suction module 22 and the second suction module 23 are respectively disposed on both sides of the second connecting block 214 in the second direction D2-D2. The second suction module 23 is configured to adsorb the cover plate 300 on the top of the carrier 200, so as to facilitate the first suction module 22 to pick up the material 400 in the carrier 200.

[0061] Please refer to Figures 5 to 7The first suction module 22 further includes a first fixing frame 223 and two second fixing frames 224. The first fixing frame 223 and the two second fixing frames 224 are respectively connected to the second connecting block 214. The two second fixing frames 224 are respectively located on both sides of the first fixing frame 223 along the first direction D1-D1. The first fixing frame 223 has a plurality of mounting slots 201 spaced apart along the first direction D1-D1, and a plurality of first driving members 221 are correspondingly arranged with the plurality of mounting slots 201. The first suction assembly 222 includes a plurality of first air passage members 2221 and a plurality of first suction members 2222 disposed on the first air passage members 2221. The driving end of each first driving member 221 is fixedly connected to the top of the first air passage member 2221, and the first suction member 2222 is disposed at the bottom of the first air passage member 2221. The first air passage member 2221 has an air passage, and the first suction member 2222 communicates with the air passage. In this application, the first air duct 2221 extends along a first direction D1-D1, and several first air ducts 2221 are arranged at intervals along a second direction D2-D2 to match the arrangement order of the materials 400 within the carrier 200. The first drive unit 221 can independently control the lifting and lowering movement of each first air duct 2221, thereby enabling selective release of the materials 400 to ensure that the materials 400 transported to the pallet meet requirements.

[0062] Each second fixing frame 224 includes a first fixing part 2241 and a second fixing part 2242. The first fixing part 2241 is fixedly connected to the second connecting block 214. The second fixing part 2242 is located at the bottom of the first fixing part 2241 and has several through holes. The position of each through hole corresponds vertically to the position of the first air passage component 2221. The air pipe of the external air source passes through the through hole and communicates with the air passage of the first air passage component 2221. The first fixing part 2241 is provided with two first connecting posts 225, which can move vertically. A pressure plate 227 is provided below the several first air passage components 2221. The pressure plate 227 is rectangular, and its outer contour is adapted to the carrier 200. The second end of each first connecting post 225 is fixedly connected to the top corner of the pressure plate 227. Two first connecting posts 225 are provided with first connecting rods 226 at their first ends to restrict the two first connecting posts 225 from moving out of the first fixing part 2241, thereby causing the pressure plate 227 to disengage from the first fixing part 2241. The pressure plate 227 has a plurality of through slots 202, the shape of which is adapted to the shape of the material 400. Each through slot 202 is arranged at intervals along the second direction D2-D2. Each first air passage 2221 is vertically opposite to each through slot 202. The first suction member 2222 on each first air passage 2221 can move up and down within the through slot 202 under the drive of the first driving member 221. Each first connecting post 225 is also fitted with a spring 228. One end of the spring 228 elastically abuts against the bottom of the first fixing part 2241, and the other end of the spring 228 elastically abuts against the pressure plate 227. In the embodiments of this application, the first suction member 2222 is a suction cup. First, the first driving component 221 drives the first air passage component 2221 to rise, making the first suction component 2222 higher than the pressure plate 227. The horizontal moving mechanism 211 of the first moving module 21 drives the first suction module 22 to move along the second direction D2-D2 to the top of the carrier 200, and the vertical moving mechanism 212 drives the first suction module 22 to move downward along the third direction D3-D3 and approach the carrier 200. At this time, the pressure plate 227 abuts against the top of the carrier 200, so that the carrier 200 exerts a certain reaction force on the pressure plate 227. The pressure plate 227 moves towards the second fixing part 2242 under the reaction force, and the spring 228 is stressed to store energy. Because the pressure plate 227 has a certain pressing effect on the carrier 200, it can reduce the risk of the first suction component 2222 sucking up the carrier 200 along with the material 400 during the suction process. When the vertical moving mechanism 212 drives the pressure plate 227 away from the carrier 200, the spring 228 releases its elastic force to push the pressure plate 227 downward, thereby restoring the pressure plate 227 to its initial position. Subsequently, the first driving member 221 drives the first air passage member 2221 to move downward along the third direction D3-D3, activating the external air source, and the first suction member 2222 opens to draw the material 400 inside the carrier 200 under negative pressure.Finally, the vertical moving mechanism 212, through the first connecting block 213 and the second connecting block 214, drives the first suction module 22 to rise upwards as a whole, while the horizontal moving mechanism 211 drives the first suction module 22 to move along the second direction D2-D2 above the tray. The external air source is then shut off, allowing the material 400 adsorbed by the first suction member 2222 to fall into the designated position on the tray. This configuration improves the handling efficiency of the material 400 and reduces its loss.

[0063] Please refer to Figures 8 to 9 The second suction module 23 includes a second drive member 231 and a second suction member 232 connected to the second drive member 231. To prevent the material 400 inside the carrier 200 from shifting or falling outside the carrier 200 before entering the automatic unloading device 100, a cover plate 300 is placed on top of the material 400 to keep it stably positioned inside the carrier 200. The second suction member 232 is configured to suction the cover plate 300 on top of the carrier 200 so that the first suction module 22 can suction the material 400.

[0064] Specifically, the second suction module 23 further includes a first fixing plate 233 and a second fixing plate 234. The second fixing plate 234 is located below the first fixing plate 233 in the third direction D3-D3. The first fixing plate 233 extends horizontally along the second direction D2-D2 and is perpendicularly connected to the second connecting block 214. A second driving member 231 is disposed on the top of the first fixing plate 233, and the driving end of the second driving member 231 passes through the first fixing plate 233 and connects to the second fixing plate 234 to drive the second fixing plate 234 to move up and down along the third direction D3-D3. The second suction module 23 also includes a first adsorption plate 235, which is disposed at the bottom of the second fixing plate 234. A plurality of second adsorption elements 232 are evenly disposed through the second fixing plate 234 and the first adsorption plate 235, and an external air source is connected to the plurality of second adsorption elements 232. When the second suction module 23 is positioned above the carrier 200, the second drive member 231 drives the first adsorption plate 235 to move downwards synchronously via the second fixed plate 234, causing the first adsorption plate 235 to adhere to the cover plate 300. The external air source is activated, and the second adsorption member 232 opens and maintains the negative pressure adsorption cover plate 300. After the first adsorption member 2222 adsorbs the material 400 within the carrier 200, the horizontal moving mechanism 211 again drives the second suction module 23 to move to the top of the carrier 200. The external air source is then turned off, and the second adsorption member 232 within the first adsorption plate 235 loses its suction force, causing the cover plate 300 located below the first adsorption plate 235 to fall back to the top of the carrier 200 under gravity. In this application, the second drive member 231 can be one of the structures capable of linear motion, such as a cylinder, hydraulic cylinder, or electric cylinder.

[0065] The second suction module 23 also includes four second connecting posts 236. The second driving member 231 has two second connecting posts 236 on each side of the first direction D1-D1. The first ends of the two second connecting posts 236 on one side are provided with second connecting rods 237. The second ends of the two second connecting posts 236 pass through the first fixing plate 233 and connect to the second fixing plate 234. When the second driving member 231 drives the second fixing plate 234 to move up and down, the second connecting posts 236 provide a certain guiding effect on the second fixing plate 234, ensuring that the second fixing plate 234 always moves along the third direction D3-D3, thus improving the accuracy of the second suction member 232 in suctioning the cover plate 300.

[0066] Please refer to Figures 10 to 11 The conveying mechanism 2 also includes a third suction module, which is mounted on the mounting plate 8 and positioned below the conveying mechanism 1. The third suction module includes a third driving member and a third adsorption member connected to the third driving member. The third driving member drives the third adsorption member upward to adsorb the bottom of the carrier 200. The third adsorption member is connected to an external air source. When the second adsorption member 232 adsorbs the cover plate 300 on top of the carrier 200, the third driving member drives the third adsorption member upward to bring it into contact with the bottom of the carrier 200. At this time, the external air source is turned on, and the third adsorption member adsorbs the bottom of the carrier 200 under negative pressure. This arrangement prevents displacement of the carrier 200 when the second adsorption member 232 adsorbs the cover plate 300. When the first adsorption member 2222 adsorbs the material 400 inside the carrier 200, the external air source is turned off, the third adsorption member loses its adsorption force, and the third driving member drives the third adsorption member downward to avoid interfering with the material 400 that the first adsorption member 2222 can selectively adsorb. In this application, the third driving component can be one of the structures capable of linear motion, such as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0067] Please refer to Figure 1 as well as Figure 10The automatic feeding device 100 also includes a detection mechanism 6, which is located at the conveying end of the conveying mechanism 1. The detection mechanism 6 detects the carrier 200 and the material 400 to identify their information. Specifically, the detection mechanism 6 includes a bracket 61 and a barcode scanner 62 mounted on the bracket 61. The bracket 61 is mounted on the mounting plate 8 and includes two first support rods 611 and a second support rod 612. The two first support rods 611 are respectively located on both sides of the two tracks 11 in the second direction D2-D2. The second support rod 612 spans the two tracks 11, and both ends of the second support rod 612 are connected to the two first support rods 611. The barcode scanner 62 is mounted on the second support rod 612. When the carrier 200 carrying the material 400 enters the input end of the track 11, the barcode scanner 62 located above the track 11 can identify the codes on the carrier 200 and the material 400 carried in the carrier 200 respectively, and upload the code information to the host computer. The host computer locates the material 400 in the carrier 200 according to the code information, in preparation for the next step of the first suction module 22 to selectively release the material 400.

[0068] Please refer to Figures 10 to 11 The automatic feeding device 100 also includes a blocking mechanism 7, which is located at the input end of the conveying mechanism 1. When the carrier 200 is being detected by the detection mechanism 6, the blocking mechanism 7 abuts against the carrier 200 to restrict the carrier 200 from continuing to move. Specifically, the blocking mechanism 7 includes a fourth driving member 71 and a blocking block 72. The fourth driving member 71 is mounted on a mounting plate 8 and is positioned between two tracks 11. When the carrier 200 moves on the track 11 below the barcode scanner 62, the fourth driving member 71 drives the blocking block 72 to rise. The blocking block 72 abuts against the front end of the carrier 200 to prevent the carrier 200 from continuing to move along the track 11, thus ensuring that the barcode scanner 62 can smoothly scan the codes on the carrier 200 and the material 400.

[0069] Please refer to Figures 1 to 3 as well as Figure 14 The automatic feeding device 100 also includes a transfer mechanism 3 and a robotic arm mechanism 4, which are disposed between the conveying mechanism 1 and the pallet. The first suction assembly 222 transports the suctioned material 400 to the transfer mechanism 3, which is configured to adjust the spacing between several material pieces 400. The robotic arm mechanism 4 is configured to transport the material pieces 400 from the transfer mechanism 3 to the pallet. Through the cooperation of the transfer mechanism 3 and the robotic arm mechanism 4, the spacing between the multiple material pieces 400 is adapted to the pallet, further improving the material handling efficiency.

[0070] Please refer to Figures 1 to 3 as well as Figure 14The transfer mechanism 3 includes a body 31, a pitch-changing drive component 32, a cam pitch-changing roller 33, and several positioning components 34. The cam pitch-changing roller 33 is rotatably disposed within the body 31. The pitch-changing drive component 32 is connected to one end of the cam pitch-changing roller 33. Several spiral guide grooves 301 are provided on the peripheral wall of the cam pitch-changing roller 33. The spiral guide grooves 301 are arranged in a mirror image along the center of the cam pitch-changing roller 33. The positioning components 34 are slidably connected to the spiral guide grooves 301. The pitch-changing drive component 32 drives the positioning components 34 to disperse or converge through the cam pitch-changing roller 33. Specifically, the spiral guide grooves 301 are annular, and the spiral guide grooves 301 at both ends of the cam pitch-changing roller 33 have a longer guide stroke than the spiral guide groove 301 in the middle. The top of the body 31 has an opening 302, and slide rails 35 are provided on both sides of the opening 302. A positioning bracket 36 is also provided between the positioning component 34 and the cam pitch-changing roller 33. The positioning bracket 36 is approximately Y-shaped and includes a first positioning part 361 and a second positioning part 362 perpendicular to one end of the first positioning part 361. The first positioning part 361 passes through the opening 302 and is slidably connected to the spiral guide groove 301. The bottom of the second positioning part 362 is slidably connected to the slide rail 35, and the positioning element 34 is fixed to the top of the second positioning part 362. The variable pitch drive 32 drives the plurality of positioning elements 34 to disperse or converge by rotating the cam variable pitch roller 33 in the forward or reverse direction. This allows adjustment of the spacing between the plurality of positioning elements 34 so that the spacing of the material 400 within the positioning elements 34 is adapted to the tray, facilitating the placement of the material 400 into the cavity of the tray.

[0071] Please refer to Figures 16 to 17 In the embodiments of this application, the transfer mechanism 3 further includes a sensor 37, and each positioning member 34 is provided with a sensor 37, so as to detect whether a material 400 is placed in the positioning member 34. The sensor 37 transmits the detection information to the host computer and records it to facilitate the verification of the quantity and model of the material 400 in each tray.

[0072] Please refer to Figure 3 as well as Figures 20 to 23The robotic arm mechanism 4 includes a robotic arm 41 and a fourth suction module 42 disposed at the end of the robotic arm 41. Specifically, the fourth suction module 42 includes a second suction plate 421 and several sets of fourth suction elements 422 disposed on the second suction plate 421. The fourth suction elements 422 are connected to an external air source, and each set of fourth suction elements 422 can suction one material 400. In the embodiment of this application, eight material 400s are placed on the carrier 200, and ten acupoints are provided in the tray. There are ten sets of fourth suction elements 422, and ten positioning elements 34 are provided on the body 31 of the transfer mechanism 3. The sensor 37 detects whether there is a material 400 in the positioning element 34. If the sensor 37 detects that there is no material 400 in the positioning element 34, then the first suction element 2222 is used to replenish the empty positioning element 34, thereby ensuring that all ten positioning elements 34 of the transfer mechanism 3 are filled with qualified material 400s. Then, the robotic arm 41 simultaneously picks up ten qualified parts 400 and places them into the cavity of the tray through the fourth adsorption element 422, thereby ensuring that each tray has a specified number of parts 400 for the next process.

[0073] Please refer to Figures 1 to 3 as well as Figures 20 to 26 The automatic unloading device 100 also includes a pallet mechanism 5, which is located on the side of the robotic arm mechanism 4 facing away from the conveying mechanism 1. The pallet mechanism 5 is configured to carry several pallets to further improve the handling efficiency of the material 400.

[0074] Pallet mechanism 5 is mounted on mounting plate 8, and is located on one side of transfer mechanism 3 along the second direction D2-D2. Pallet mechanism 5 includes a first pallet station 51, a second pallet station 52, and a third pallet station 53. (See attached diagram.) Figure 3 As shown, the first pallet station 51 and the second pallet station 52 are arranged adjacent to each other along the first direction D1-D1. The third pallet station 53 is located between the first pallet station 51 and the transfer mechanism 3. The third pallet station 53 reciprocates between the first pallet station 51 and the second pallet station 52. The first pallet station 51 is configured to transport empty pallets to the third pallet station 53 to be able to carry the material 400 adsorbed by the robotic arm mechanism 4, and the second pallet station 52 is configured to carry the pallet of the fully loaded material 400 transported by the third pallet station 53. (See attached diagram) Figure 3As shown, the first pallet station 51 and the second pallet station 52 are arranged side by side on the mounting plate 8 along the first direction D1-D1, with the first pallet station 51 and the second pallet station 52 arranged in the same row. The third pallet station 53 is movably mounted on the mounting plate 8, with the first pallet station 51 and the second pallet station 52 on both sides of the third pallet station 53. The first pallet station 51 includes a first pallet frame 511, a first lifting drive 512, a pallet separating component 513, and a first conveying component 514. The first pallet frame 511 has a hollow rectangular frame structure. The first lifting drive 512 is disposed inside the first pallet frame 511, the pallet separating component 513 is disposed on the first pallet frame 511, and the first conveying component 514 is disposed on the inner side of the first pallet frame 511. Multiple empty pallets are placed inside the first pallet frame 511. The pallet separating component 513 is inserted into the gap between the last two pallets to lift the second to last pallet. The first lifting drive 512 descends to separate the bottommost pallet. The separated pallets are moved to the third pallet station 53 via the first conveyor 514. The third pallet station 53 includes a third pallet station drive 531, a moving track 532, a third pallet frame 533, and a third conveyor 534. The moving track 532 is disposed on the mounting plate 8 along the first direction D1-D1, and the third pallet frame 533 is disposed on the moving track 532. The third pallet station drive 531 is connected to the third pallet frame 533 to drive the third pallet frame 533 to move on the moving track 532. When the third pallet station drive 531 drives the third pallet frame 533 to dock with the first pallet frame 511, the first conveyor 514 and the third conveyor 534 transport synchronously, so that the empty pallet is transported from the first pallet frame 511 to the third pallet frame 533 via the first conveyor 514, thereby receiving the material 400 adsorbed by the fourth suction module 42 on the robotic arm 41. The second pallet station 52 includes a second pallet frame 521, a second lifting drive 522, a buckle 523, an optical fiber detector 524, and a second conveyor 525. The second pallet frame 521 has a hollow rectangular frame structure and is located beside the first pallet frame 511. The second lifting drive 522 is located inside the second pallet frame 521, the buckle 523 is located on the second pallet frame 521, the second conveyor 525 is located inside the second pallet frame 521, and the optical fiber detector 524 is located on the top of the second pallet frame 521. After the fourth suction module 42 of the robotic arm 41 places the suctioned material 400 onto a pallet located in the third pallet rack 533, the third pallet station drive 531 drives the third pallet rack 533 to move along the moving track 532 to the second pallet rack 521 and dock. The third conveyor 534 and the second conveyor 525 are activated to transport the pallet filled with material 400 from the third pallet rack 533 to the second pallet rack 521. At this time, the second lifting drive 522 drives the pallet to rise and engage unidirectionally with the latch 523 on the second pallet rack 521, so that the second pallet rack 521 can receive the next pallet.The fiber optic detector 524 at the top of the second pallet rack 521 detects the number of pallets stacked within the second pallet rack 521 to ensure the stability of the pallet stacking. In this embodiment, the number of pallets stacked within the first pallet rack 511 and the second pallet rack 521 does not exceed a certain number.

[0075] In the embodiments of this application, the conveying mechanism 1 includes two sets, which are arranged side by side along a first direction D1-D1. The handling mechanism 2 includes two sets, with one set located at a second position 102 of the conveying mechanism 1. The two sets of handling mechanisms 2 are arranged facing each other to pick up and selectively release the material 400 within the carrier 200 on the other set of conveying mechanisms 1. The transfer mechanism 3 includes two sets, each arranged along a first direction D1-D1 on one side of the conveying mechanism 1. The other set of transfer mechanisms 3 is configured to adjust the spacing between the material 400 within the carrier 200 at the second position 102. The pallet mechanism 5 includes two sets, which are arranged adjacent to each other. The robotic arm mechanism 4 is located between the two sets of pallet mechanisms 5 and rotates between them to simultaneously transport the material 400 from the two sets of transfer mechanisms 3 to the corresponding pallet mechanism 5. This arrangement significantly improves the working efficiency of the automatic unloading device 100.

[0076] The automatic feeding device 100 also includes a recycling mechanism 9, which is located at the second position 102. The recycling mechanism 9 is positioned opposite to the conveying mechanism 2 at the second position 102. The recycling mechanism 9 includes a recycling moving module 91 and a fifth adsorption module 92 and a sixth adsorption module 93 disposed on the recycling moving module 91. The fifth adsorption module 92 is configured to absorb the cover plate 300 on the carrier 200, and the sixth adsorption module 93 is configured to absorb waste material inside the carrier 200. The structure of the recycling moving module 91 is the same as that of the first moving module 21, and the structures of the fifth adsorption module 92 and the sixth adsorption module 93 are the same as those of the second adsorption module 23, which will not be described in detail here. After the conveying mechanism 2 selectively absorbs the material 400 and transports the material 400 to the corresponding transfer mechanism 3, the two sets of conveying mechanisms 1 continue to transport the carrier 200 to below the recycling mechanism 9. The recycling moving module 91 drives the fifth adsorption module 92 to move to the top of the carrier 200. The fifth adsorption module 92 picks up the cover plate 300. The recycling moving module 91 then drives the sixth adsorption module 93 to move to the top of the carrier 200, where the sixth adsorption module 93 picks up the waste inside the carrier 200. The recycling moving module 91 drives the fifth adsorption module 92 to move above the carrier 200 and release the cover plate 300, allowing it to be placed back on top of the carrier 200 for later use, thus improving the recycling efficiency of the carrier 200.

[0077] Please refer to Figure 3In this embodiment, the mounting plate 8 is provided with a first collection port 801, a second collection port 802, and a third collection port 803. The first collection port 801 is located at the first position 101 of the conveying mechanism 1, and corresponds vertically to the second suction module 23 at the first position 101, used to collect unselected material 400 adsorbed by the second suction module 23 at the first position 101. The second collection port 802 is located at the second position 102 of the conveying mechanism 1, and corresponds vertically to the second suction module 23 at the second position 102, used to collect unselected material 400 adsorbed by the second suction module 23 at the second position 102. The third collection port 803 is located at the second position 102 of the conveying mechanism 1, and corresponds vertically to the sixth suction module 93 at the second position 102, used to collect waste adsorbed by the sixth suction module 93. This arrangement facilitates the collection of material 400 and waste, maintaining a safe and clean environment for the device.

[0078] In summary, this application discloses an automatic feeding device 100, which includes a conveying mechanism 1 and a handling mechanism 2. The conveying mechanism 1 transports a carrier 200 along a first direction D1-D1. The handling mechanism 2 includes a first moving module 21 and a first suction module 22 disposed at the drive end of the first moving module 21. The first suction module 22 includes multiple first driving members 221 and multiple first suction components 222. By connecting each first driving member 221 to a corresponding first suction component 222, the first driving member 221 drives the corresponding first suction component 222 to move up and down, thereby enabling the suction of a material 400 and the selective release of the material 400. This not only improves the handling efficiency of the material 400 but also reduces the loss of the material 400.
