Description

Technical Field

[0001] This invention relates to the field of material feeding technology, and in particular to a feeding device for sheet materials. Background Technology

[0002] like Figure 1 and Figure 2 As shown, in the prior art, a material tray for holding sheet materials generally consists of a three-layer structure. Specifically, the material tray includes a carrier plate 110, a bottom plate 120, and a cover plate 130. The carrier plate 110, bottom plate 120, and cover plate 130 are respectively provided with a first hole 111, a second hole 121, and a third hole 131. The sheet material is adhered to a material strip, which in turn is adhered to the bottom plate 120. The sheet material is also attached to the second hole 121 on the bottom plate 120. 1. The base plate 120 is placed above the carrier plate 110, and the second hole 121 is directly opposite the first hole 111. The cover plate 130 covers the base plate 120, and the third hole 131 is directly opposite the second hole 121. The base plate 120 can be clamped and confined between the carrier plate 110 and the cover plate 130, and the material strip can be clamped and confined between the cover plate 130 and the base plate 120, thereby preventing the sheet material from shifting during the transfer of the material tray.

[0003] When the material tray is transferred to the material processing equipment, the sheet material is removed from the tray through a loading operation and conveyed to the processing unit of the material processing equipment. In the prior art, the loading operation of the sheet material is usually done manually. Specifically, the operator passes one hand through the first hole 111 on the carrier plate 110 to push the sheet material out through the third hole 131 on the cover plate 130. At the same time, the operator's other hand picks up the sheet material pushed out through the third hole 131 on the cover plate 130, thereby peeling the sheet material off the conveyor belt. Afterwards, the operator feeds the removed sheet material to the processing unit of the material processing equipment. However, manual loading is inefficient, resulting in low production efficiency of the material processing equipment.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0041] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0044] Based on the content mentioned above, such as Figure 1 and Figure 2 As shown, in the prior art, the tray for holding sheet materials generally consists of a three-layer structure. Specifically, the tray includes a carrier plate 110, a bottom plate 120, and a cover plate 130. The bottom plate 120 is provided with a plurality of second holes 121, that is, a plurality of sheet materials are placed on the bottom plate 120. Correspondingly, the carrier plate 110 is provided with a plurality of first holes 111, and the cover plate 130 is provided with a plurality of third holes 131. The carrier plate 110 and the cover plate 130 can clamp and limit the strip of material with sheet materials attached, thereby preventing the sheet materials from shifting during the transfer of the tray.

[0045] In existing technology, the feeding of sheet materials is usually done manually. Specifically, the worker inserts one hand through the first hole 111 on the carrier plate 110 to push the sheet material out through the third hole 131 on the cover plate 130. At the same time, the worker's other hand picks up the sheet material pushed out through the third hole 131 on the cover plate 130, thus peeling the sheet material off the conveyor belt. Afterward, the worker feeds the removed sheet material to the processing device of the material processing equipment. However, manual feeding is inefficient, resulting in low production efficiency of the material processing equipment.

[0046] To resolve the above issues, please refer to [link / reference]. Figures 3 to 11This embodiment provides a feeding device for sheet materials. The feeding device includes a platform 210 and a feeding mechanism 220. The platform 210 is provided with two or more bearing positions 211, which are evenly arranged around a first axis 1. A material tray is placed at each bearing position 211. The feeding mechanism 220 includes two or more push rods 221, which are evenly arranged around a second axis 2 and correspond one-to-one with the two or more bearing positions 211. The second axis 2 is parallel to the first axis 1. The center of the push rod 221 is... The distance between the line and the second axis 2 is equal to the distance between the center of the bearing position 211 and the first axis 1. The top rod 221 can rise and fall in the vertical direction. The material handling mechanism 230 includes two or more suction nozzles 231. The two or more suction nozzles 231 are evenly arranged around the third axis 3 and correspond one-to-one with the two or more bearing positions 211. The third axis 3 is parallel to the first axis 1. The distance between the center line of the suction hole of the suction nozzle 231 and the second axis 2 is equal to the distance between the center of the bearing position 211 and the first axis 1. All suction nozzles 231 can move synchronously in the vertical direction.

[0047] For example, the platform 210 is provided with four bearing positions 211. Correspondingly, the feeding mechanism 220 includes four push rods 221, and the picking mechanism 230 includes four suction nozzles 231. Of course, in other optional embodiments, the platform 210 may also be provided with two, three, five or other numbers of bearing positions 211. Correspondingly, the feeding mechanism 220 may also be provided with two, three, five or other numbers of push rods 221, and the picking mechanism 230 may also be provided with two, three, five or other numbers of suction nozzles 231. This embodiment does not impose specific limitations on this.

[0048] In addition to the platform 210 and the feeding mechanism 220, the feeding device for sheet materials in this embodiment also includes a first driving module 240 and a second driving module. The first driving module 240 can drive two or more push rods 221 to move synchronously in the horizontal direction, while the second driving module can drive two or more suction nozzles 231 to move synchronously in the horizontal direction and can drive two or more suction nozzles 231 to rotate around the third axis 3.

[0049] In this embodiment, a material tray is placed on the platform 210. The push rod 221 can move horizontally and rise vertically to lift the sheet material in the tray one by one. The suction nozzle 231 can move horizontally so that it aligns with the sheet material after the push rod 221 lifts it. The suction nozzle 231 can also descend vertically to suck up the lifted sheet material, thereby peeling the sheet material off the conveyor belt.

[0050] Since the distance between the center line of the push rod 221 and the second axis 2 is equal to the distance between the center of the bearing position 211 and the first axis 1, after two or more push rods 221 move synchronously in the horizontal direction, they can be aligned with the sheet material located at the same position in two or more material trays at the same time. In addition, since the distance between the center line of the suction hole of the suction nozzle 231 and the second axis 2 is equal to the distance between the center of the bearing position 211 and the first axis 1, after two or more suction nozzles 231 move synchronously in the horizontal direction, they can be aligned with the sheet material that has been pushed up in two or more material trays at the same time. After that, two or more suction nozzles 231 can simultaneously suck up the sheet material.

[0051] After two or more push rods 221 eject sheet-like materials located at the same position in two or more trays, and two or more suction nozzles 231 peel off the sheet-like materials located at the same position in two or more trays, the two or more suction nozzles 231 can move synchronously in the horizontal direction, thereby supplying the peeled sheet-like materials to the processing device of the material processing equipment, thus completing one loading operation. Afterwards, the two or more suction nozzles 231 move synchronously in the horizontal direction, thereby synchronously returning to their positions above the platform 210 for the next loading operation. In this embodiment, the second drive module can drive the two or more suction nozzles 231 to rotate around the third axis 3, thereby correcting the position of the two or more suction nozzles 231 after they synchronously return to their positions above the platform 210, ensuring that the two or more suction nozzles 231 maintain the same posture as the two or more push rods 221, and thus ensuring that the two or more suction nozzles 231 can accurately align with the sheet-like materials ejected in the two or more trays after continuing to move synchronously in the horizontal direction.

[0052] Based on the above, in this embodiment, the sheet materials in the material trays are ejected one by one by the push rods 221, and the ejected sheet materials are sucked up by the suction nozzles 231, thereby peeling the sheet materials off the conveyor belt one by one. Furthermore, after two or more push rods 221 move synchronously in the horizontal direction, they can simultaneously align with the sheet materials located at the same position in two or more material trays, and after two or more suction nozzles 231 move synchronously in the horizontal direction, they can simultaneously align with the ejected sheet materials in two or more material trays, thus enabling the simultaneous peeling of sheet materials located at the same position in two or more material trays in one operation. After the two or more suction nozzles 231 have peeled the sheet materials located at the same position in two or more material trays, the two or more suction nozzles 231 can move synchronously in the horizontal direction, thereby supplying the peeled sheet materials to the processing device of the material processing equipment. Compared with manual feeding, the sheet material feeding device in this embodiment has high working efficiency, thereby improving the production efficiency of the material processing equipment.

[0053] Preferably, the second drive module in this embodiment includes a first drive component 251. A rotating shaft 234 is mounted on the movable end of the first drive component 251. The axis of the rotating shaft 234 is the third axis 3 mentioned above. All suction nozzles 231 are mounted on a first mounting plate 233. The first mounting plate 233 is fixedly connected to the rotating shaft 234. The first drive component 251 is configured to drive the rotating shaft 234 to rotate around its axis, thereby driving two or more suction nozzles 231 to rotate around the third axis 3.

[0054] It is understood that the first driving component 251 can be selected as a stepper motor or a servo motor or other driving structure, and this embodiment does not impose specific restrictions on it.

[0055] Furthermore, the feeding device for sheet materials also includes a photoelectric sensor 270, which is configured to detect the rotation angle of the rotating shaft 234. This allows for precise correction of the position of the two or more suction nozzles 231 after they have returned synchronously to the top of the platform 210. This ensures that the two or more suction nozzles 231 maintain the same posture as the two or more push rods 221, and further ensures that the two or more suction nozzles 231 can accurately align with the sheet materials being pushed up in the two or more material trays after they continue to move synchronously in the horizontal direction.

[0056] It should be noted that since the photoelectric sensor 270 is a conventional structure composed of a light-shielding plate and a slotted photoelectric switch, it will not be described in detail in this embodiment.

[0057] In addition, the second drive module also includes a first X-axis movement module (not shown in the figure), a first Y-axis movement module (not shown in the figure), and a Z-axis movement module (not shown in the figure). The Z-axis movement module is used to drive the rotating shaft 234 and the first mounting plate 233 to move along the Z-axis direction, which is the vertical direction. The first X-axis movement module can drive the rotating shaft 234 and the first mounting plate 233 to move along the X-axis direction. The first Y-axis movement module can drive the rotating shaft 234 and the first mounting plate 233 to move along the Y-axis direction. The X-axis, Y-axis, and Z-axis are perpendicular to each other, that is, the first X-axis movement module and the first Y-axis movement module can enable two or more suction nozzles 231 to move synchronously in the horizontal direction.

[0058] It is understood that the first X-axis moving module, the first Y-axis moving module, and the Z-axis moving module can all be selected as linear drive structures such as KK modules or cylinders, and no specific restrictions are imposed on this in this embodiment.

[0059] Furthermore, in this embodiment, the rotating shaft 234 includes a first shaft portion 2341 and a second shaft portion 2342. All suction nozzles 231 are mounted on the first shaft portion 2341, and the second shaft portion 2342 is slidably connected to the first shaft portion 2341 in the vertical direction. A buffer spring 2343 is connected between the first shaft portion 2341 and the second shaft portion 2342. The buffer spring 2343 extends in the vertical direction so that the suction nozzles 231 can flexibly contact the sheet material, thereby avoiding damage to the sheet material.

[0060] All the push rods 221 are mounted on the second mounting plate 222. The first drive module 240 includes a second X-axis moving module 241 and a second Y-axis moving module 242. The second X-axis moving module 241 can drive the second mounting plate 222 to move along the X-axis direction, and the second Y-axis moving module 242 can drive the second mounting plate 222 to move along the Y-axis direction, so that two or more push rods 221 move synchronously in the horizontal direction.

[0061] It is understood that the second X-axis moving module 241 and the second Y-axis moving module 242 can both be selected as linear drive structures such as KK modules or cylinders, and no specific restrictions are made in this embodiment.

[0062] Preferably, a mounting base 223 is fixedly connected to the second mounting plate 222, and a second driving member 224 is fixedly connected to the mounting base 223. The push rod 221 is installed on the movable end of the second driving member 224. That is, in this embodiment, each push rod 221 is correspondingly provided with a second driving member 224. The second driving member 224 is configured to drive the push rod 221 to rise and fall in the vertical direction, thereby lifting the sheet material in the tray.

[0063] It is understood that the second driving component 224 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and no specific restrictions are made on this in this embodiment.

[0064] Furthermore, a pin 225 is installed on the movable end of the second driving member 224. The pin 225 extends vertically, and the push rod 221 is fixedly connected to the top of the pin 225. The second driving member 224 is configured to drive the pin 225 to rise and fall vertically. The mounting base 223 is sleeved on the outer periphery of the pin 225 through a pin sleeve 226. The pin sleeve 226 can provide guidance for the vertical movement of the push rod 221, thereby ensuring that the push rod 221 can accurately lift the sheet material in the tray.

[0065] In addition, the top of the push rod 221 is covered with a silicone layer to allow the push rod 221 to make flexible contact with the sheet material, thereby further avoiding damage to the sheet material.

[0066] Preferably, the feeding device for sheet materials further includes a clamping module. All bearing positions 211 are equipped with clamping modules. The clamping modules are configured to clamp the material tray, thereby positioning the material tray to further ensure that the top rod 221 can accurately lift the sheet material in the material tray and ensure that the suction nozzle 231 can accurately peel the sheet material from the conveyor belt.

[0067] like Figure 1 and Figure 2 As shown, the material tray has a first inclined surface 140 and a second inclined surface 150 on both sides, respectively. Please refer to [link / reference]. Figures 9 to 11 The clamping module preferably includes a first clamping component 261 and a second clamping component 262, which are located on both sides of the bearing position 211. The first clamping component 261 includes a first pressure plate 2611 and a first roller 2612, with the first roller 2612 located below the first pressure plate 2611. The second clamping component 262 includes a second pressure plate 2621 and a second roller 2622, with the second roller 2622 located below the second pressure plate 2621. The first roller 2612 and the second roller 2622 are flush, as are the first pressure plate 2611 and the second pressure plate 2621. The first clamping component 261 and the second clamping component 262 are capable of relative movement to allow material to move. One side of the tray can extend between the first roller 2612 and the first pressure plate 2611, and the other side of the tray can extend between the second roller 2622 and the second pressure plate 2621. The first roller 2612 can push against the first inclined surface 140, and the second roller 2622 can push against the second inclined surface 150, so that the tray rises vertically and clamps the tray between the first roller 2612 and the first pressure plate 2611, as well as between the second roller 2622 and the second pressure plate 2621, to ensure that the tray is placed horizontally. This ensures that all suction nozzles 231 can pick up sheet materials in the same horizontal plane, that is, to ensure that two or more suction nozzles 231 can simultaneously peel sheet materials in the same position in two or more trays at one time.

[0068] It is understood that both the first clamping component 261 and the second clamping component 262 are driven by the driving cylinder 263, so that they can move relative to each other. The model of the driving cylinder 263 corresponding to any first clamping component 261 and any second clamping component 262 can be selected according to actual needs. In this embodiment, no specific restrictions are imposed on this.

[0069] In addition, the material handling mechanism 230 in this embodiment also includes a leveling module. The leveling module is configured to ensure that all suction nozzles 231 are located in the same horizontal plane, thereby further ensuring that two or more suction nozzles 231 can simultaneously peel off sheet-like materials located in the same position in two or more material trays at one time.

[0070] like Figure 6As shown, the leveling module includes a rotating ball 2321 and leveling bolts 2322. The suction nozzle 231 and the first mounting plate 233 are together sleeved on the outer periphery of the rotating ball 2321. The suction nozzle 231 and the first mounting plate 233 are fixedly connected by the leveling bolts 2322. Multiple leveling bolts 2322 are provided on the outer periphery of the rotating ball 2321. The multiple leveling bolts 2322 are evenly arranged around the rotating ball 2321. In this embodiment, the suction nozzle 231 can be rotated in any direction around the rotating ball 2321 by turning the leveling bolts 2322 on the outer periphery of the suction nozzle 231, thereby adjusting the levelness of the suction nozzle 231 and making all suction nozzles 231 in the same horizontal plane.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
