[0046] It should be noted that the material conveying device provided in the embodiment of the present application is particularly suitable for assembly scenarios where only mechanical assembly can be used and visual positioning guidance cannot be used, such as scenarios where the material and the parts to be assembled are similar in color.

[0047] Please refer to Figure 1-Figure 4 , Figure 1 This is a structural diagram of a material conveying device provided in an embodiment of the present application. Figure 1The material conveying device in the invention comprises a fixed base 10, a storage bin 20, a material error platform 30 and a material suction member 40; the storage bin 20 is fixedly connected to the fixed base 10, the storage bin 20 is provided with a storage cavity 21, the storage bin 20 is provided with a material inlet and outlet 22 at one end close to the fixed base 10, the material inlet and outlet 22 is communicated with the storage cavity 21, and the storage cavity 21 can accommodate a plurality of target materials; the material error platform 30 is arranged between the storage bin 20 and the fixed base 10, the material error platform 30 is slidably connected to the fixed base 10, the material error platform 30 is provided with a loading port 31, and when the material error platform 30 slides relative to the fixed base 10 When it moves to the first position, the loading port 31 matches the position of the material inlet and outlet 22; the suction member 40 is arranged on the side of the material error platform 30 facing the storage bin 20, and the end of the suction member 40 close to the material error platform 30 is provided with a material adsorption end 41; the side of the material error platform 30 facing the storage bin 20 is provided with a material receiving position 32, and when the material error platform 30 slides to the second position relative to the fixed base 10, the material receiving position 32 matches the position of the material inlet and outlet 22, and when the material error platform 30 slides to the third position relative to the fixed base 10, the material receiving position 32 matches the position of the material adsorption end 41.

[0048] In some embodiments, the target material includes but is not limited to materials with small dimensions or irregular shapes. For example, the target material may be a rectangular magnet with a length, width and height of 3 mm*0.8 mm*0.6 mm.

[0049] In some embodiments, the storage bin 20 is disposed above the fixed base 10 . The storage bin 20 is a clip-type bin. The storage cavity 21 is used to accommodate multiple target materials. The material entrance and exit 22 is used to allow multiple target materials to enter or exit the storage cavity 21 .

[0050] In some embodiments, a plurality of target materials are stacked and arranged in the storage cavity 21. Specifically, the stacking and arrangement directions include but are not limited to the length direction, width direction, and height direction of the target materials.

[0051] For example, 25 mini rectangular parallelepiped magnets with a length, width and height of 3 mm*0.8 mm*0.6 mm are stacked and arranged in the storage cavity 21 along the height direction of the mini rectangular parallelepiped magnets.

[0052] Furthermore, one of the material error platform 30 and the fixed base 10 is provided with a first slide rail, and the other is provided with a first sliding part sliding in the first slide rail, so that a guided sliding connection is achieved between the material error platform 30 and the fixed base 10.

[0053] In some embodiments, a first slide rail is provided on the fixed base 10, and correspondingly, a first sliding portion sliding in the first slide rail is provided on the material error platform 30, thereby realizing a guided sliding connection between the material error platform 30 and the fixed base 10.

[0054] Please refer to Figure 4 In some embodiments, the material conveying device further includes a power adsorption device 160, the material adsorption member 40 is fixedly connected to the top of the fixed base 10, and the material adsorption member 40 is provided with a material adsorption end 41 and a suction end that are connected, and the suction end is connected to the power adsorption device 160. Under the first power action of the power adsorption device 160, the material adsorption end 41 is used to adsorb or release the target material.

[0055] In some embodiments, the loading port 31 passes through the material misalignment platform 30. When the material misalignment platform 30 slides to the first position, the position of the loading port 31 matches the position of the material inlet and outlet 22. Specifically, the loading port 31 can be located directly below the material inlet and outlet 22. In this way, the target material can be accurately transferred into the storage cavity 21 through the guidance of the loading port 31, which is conducive to improving the assembly accuracy of the target material. In addition, the placement of the loading port 31 on the material misalignment platform 30 can reduce the structural complexity of the material conveying device and reduce the volume of the material conveying device.

[0056] In some embodiments, before the target materials are loaded, the target materials can be pre-stacked and arranged by discharging the target materials through a vibrating plate, and then the pre-stacked target materials are loaded into the storage cavity 21 through the loading port 31. Loading refers to transferring the target materials into the storage cavity 21.

[0057] In some embodiments, the material conveying device further includes an air extraction device, which is provided with an air extraction end that is in communication with the material storage cavity 21. During the loading process of the plurality of pre-stacked target materials, the air extraction device is simultaneously activated. Under the action of the second power of the air extraction device, the air extraction end extracts gas from the material storage cavity 21, thereby better arranging the plurality of pre-stacked target materials within the material storage cavity 21, thereby ensuring smooth discharge of the target materials. When the loading of the plurality of pre-stacked target materials is completed, the air extraction device is closed. Here, discharge refers to the target materials falling from the material storage cavity 21.

[0058] In some embodiments, when the material misalignment platform 30 slides to the second position, the position of the material receiving position 32 matches the position of the material inlet and outlet 22. Specifically, the material receiving position 32 can be located directly below the material inlet and outlet 22. In this way, the target material falls through the material inlet and outlet 22 to the material receiving position 32.

[0059] In some embodiments, the material receiving position 32 is provided with a material receiving cavity capable of accommodating one target material. Specifically, during a unit material dropping process, only one target material drops into the material receiving cavity of the material receiving position 32 through the material inlet and outlet 22 .

[0060] In some embodiments, when the material handling platform 30 slides to the third position, the position of the material receiving position 32 matches the position of the material suction end 41. Specifically, the material receiving position 32 can be located directly below the material suction end 41. This allows the material suction end 41 to conveniently absorb the target material and remove the target material. Removal refers to the material suction end 41 sucking and removing the target material from the material receiving position 32.

[0061] The material conveying device of the present application includes a storage bin capable of accommodating multiple target materials, and a material error platform provided with a loading port and a material receiving position. The material error platform can reciprocate between the storage bin and the material suction part, which can significantly improve the assembly efficiency of the target materials, and the structure is simple and easy to debug.

[0062] In an embodiment of the present application, the material conveying device also includes a material blocking member 80, which is arranged on the side of the material inlet and outlet 22, and the material blocking member 80 is slidingly connected to the fixed base 10; the material blocking member 80 can slide relative to the fixed base 10 until the position of the material blocking member 80 matches the position of the material inlet and outlet 22.

[0063] Please refer to Figure 9 In some embodiments, a material stopping end 81 is provided at one end of the material stopping member 80 close to the material inlet and outlet 22. When multiple target materials are loaded, the material stopping member 80 slides relative to the fixed base 10 until the material stopping end 81 abuts against the target material arranged in the material storage cavity 21 closest to the material inlet and outlet 22 to prevent the target material from falling from the loading port 31.

[0064] Preferably, the moving direction of the material blocking end 81 is perpendicular to the moving direction of the target material. Specifically, the moving direction of the material blocking end 81 is perpendicular to the loading / dropping direction of the target material.

[0065] Preferably, the material blocking end 81 is inserted into the material storage cavity 21 , and a structural surface of the material blocking end 81 close to the material misalignment platform 30 is aligned with the material inlet and outlet 22 .

[0066] Preferably, the dimension of the blocking end 81 along the moving direction of the target material is consistent with the unit blanking height of the target material.

[0067] In some embodiments, the material conveying device further includes a sliding seat, which is disposed on a side of the material inlet and outlet 22 and is fixedly connected to the fixed base 10 .

[0068] Furthermore, one of the sliding seat and the material stopper 80 is provided with a second slide rail, and the other is provided with a second sliding portion sliding in the second slide rail, so that a sliding connection between the sliding seat and the material stopper 8 is achieved.

[0069] In some embodiments, a second slide rail is provided in the sliding seat, and correspondingly, a second sliding portion that slides in the second slide rail is provided on the material stopper 80, thereby realizing a guided sliding connection between the sliding seat and the material stopper 80.

[0070] Please refer to Figure 9 In some embodiments, the material conveying device also includes a material blocking member driving device 150, which is connected to the material blocking member by transmission. Under the drive of the material blocking member driving device 150, the material blocking member 80 can slide relative to the sliding seat until the material blocking end 81 matches the position of the material inlet and outlet 22, or is away from the material inlet and outlet 22.

[0071] In the embodiment of the present application, a transition position 33 is provided on the side of the material error platform 30 facing the storage bin 20, and the height of the transition position 33 is higher than the material receiving position 32; during the movement of the material error platform 30 between the second position and the third position, the transition position 33 abuts against the material entrance and exit 22.

[0072] Preferably, the height difference between the transition position 33 and the receiving position 32 is consistent with the unit blanking height of the target material. In this way, the blanking accuracy of the target material can be guaranteed, and thus the assembly accuracy of the target material can be guaranteed.

[0073] Please refer to Figure 4 and Figure 5 In some embodiments, the loading port 31 and the transition position 33 are disposed continuously in the sliding direction of the material misalignment platform 30 relative to the fixed base 10. When the material misalignment platform 30 moves from the first position to the second position and reciprocates between the second position and the third position, the transition position 33 abuts against the material inlet and outlet 22.

[0074] Specifically, when the material error platform 30 moves from the first position to the second position, the transition position 33 abuts against the material inlet and outlet 22. At this time, the material blocking member 80 slides relative to the fixed base 10 until the material blocking end 81 slides relative to the fixed base 10 away from the material inlet and outlet 22. As a result, the target material falls to the transition position 33.

[0075] Specifically, when the material misalignment platform 30 slides to the second position relative to the fixed base 10 , the material receiving position 32 matches the position of the material inlet and outlet 22 , and thus the target material falls to the material receiving position 32 .

[0076] Specifically, after the target material falls to the material receiving position 32, the material misalignment platform 30 slides relative to the fixed base 10 from the second position to the third position until the material receiving position 32 matches the position of the material suction end 41. During the sliding process of the material misalignment platform 30 relative to the fixed base 10 from the second position to the third position, the transition position 33 abuts against the material inlet and outlet 22.

[0077] In an embodiment of the present application, the material conveying device includes a pressing rod 50, which is slidingly connected to the storage bin 20; the pressing rod 50 is provided with a material pressing end 51, which is arranged in the storage cavity 21, and the pressing rod 50 can move toward or away from the material inlet and outlet 22.

[0078] Please refer to Figure 3 In some embodiments, the movement direction of the press rod 50 is consistent with the movement direction of the target material. Specifically, the movement direction of the press rod 50 is consistent with the loading / dropping direction of the target material.

[0079] In some embodiments, the material pressing end 51 is disposed at one end of the pressing rod 50 near the material inlet and outlet 22. The material pressing end 51 is inserted into the material storage cavity 21 and is configured to abut the target material in the material storage cavity 21. Thus, under the action of gravity of the pressing rod 50, the material pressing end 51 pushes the target material, causing the target material to fall from the material inlet and outlet 22 to the material stop end 81 / transition position 33 / receiving position 32.

[0080] Preferably, the material pressing end 51 is a material profiling end having a shape similar to that of the target material, so that the material pressing end 51 can better push the target material.

[0081] In some embodiments, a slideway adapted to the pressing rod 50 is provided in the storage bin 20 , the slideway is communicated with the storage cavity 21 , and the pressing rod 50 slides in the slideway to realize a sliding connection between the pressing rod 50 and the storage bin 20 .

[0082] In this embodiment of the present application, the material conveying device further includes a limiting pressure plate 60, which is disposed on the side of the material misalignment platform 30 facing the material storage bin 20. The limiting pressure plate 60 is fixedly connected to the fixed base 10, and a material limiting groove 61 is provided on the side of the limiting pressure plate 60 facing the material misalignment platform 30. This achieves limited guidance of the target material during conveying, improves the conveying accuracy of the target material, and further significantly improves the assembly accuracy of the target material.

[0083] In some embodiments, the limiting pressure plate 60 is arranged above the material error platform 30, and the material limiting groove 61 is arranged toward the material error platform 30, and an accommodating space capable of accommodating the target material is formed in the material limiting groove 61.

[0084] Please refer to Figure 7 and Figure 8In some embodiments, the limiting pressure plate 60 is a split structure. Perpendicular to the movement direction of the material error platform 30, the limiting pressure plate 60 includes a left limiting pressure plate 62 and a right limiting pressure plate 63 that are arranged in conjunction with each other. The left limiting pressure plate 62 is provided with a left material limiting structure 64 on the side facing the material error platform 30, and the right limiting pressure plate 63 is provided with a right material limiting structure 65 on the side facing the material error platform 30. A material limiting groove 61 is formed between the left material limiting structure 64 and the right material limiting structure 65.

[0085] In some embodiments, the material limiting groove 61 is a multi-step groove, which cooperates with the material error platform 30 and can accommodate the target material. In this way, in the process of the material error platform 30 coordinating the target material to move from the second position to the third position, the limiting guidance of the target material is realized.

[0086] In some embodiments, a first inclined guide portion is provided at one end of the material stop groove 61 near the material inlet and outlet 22. As the material misalignment platform 30 moves from the second position to the third position, the cross-sectional area of ​​the first inclined guide portion gradually decreases until it conforms to the target material. The first inclined guide portion accurately guides the target material into the material stop groove 61, allowing the material misalignment platform 30 and the target material to smoothly pass through the material stop groove 61 to the third position.

[0087] In the embodiment of the present application, the material conveying device further includes a stopper 70 , which is disposed on the end side of the material error platform 30 . The stopper 70 is fixedly connected to the fixed base 10 , and is disposed toward the material receiving position 32 .

[0088] Please refer to Figure 3 and Figure 11 In some embodiments, the stopper 70 is arranged on one side of the movement direction of the material error platform 30, and a material blocking end 71 is provided at one end of the stopper 70 close to the material error platform 30. The material blocking end 71 is used to stop the target material to prevent the target material from being unable to be accurately maintained on the receiving position 32 due to the action of inertia when the material error platform 30 cooperates with the target material to move to the third position.

[0089] In some embodiments, in the sliding direction of the material error platform 30 relative to the fixed base 10, the material level 32 and the transition position 33 are continuously arranged, and the end of the transition position 33 close to the stop block 70 is used to limit the target material.

[0090] In an embodiment of the present application, the material conveying device also includes a guide block 90, which is arranged below the material adsorption end 41, and the guide block 90 is fixedly connected to the fixed base 10; the guide block 90 is provided with a material posture adjustment part 91, and the material adsorption end 41 can cooperate with the target material to pass through the material posture adjustment part 91.

[0091] Please refer to Figure 10In some embodiments, the material posture adjustment portion 91 passes through the guide block 90 along the movement direction of the suction member 40, and the suction member 40 can cooperate with the target material to pass through the material posture adjustment portion 91, thereby achieving the adjustment of the target material posture, which is beneficial to improving the assembly accuracy of the target material.

[0092] In some embodiments, a second inclined guide portion is provided at one end of the material posture adjustment portion 91, near the material misalignment platform 30. As the suction element 40 and the target material move through the material posture adjustment portion 91, the cross-sectional area of ​​the second inclined guide portion gradually decreases until it conforms to the target material. This second inclined guide portion accurately guides the target material toward the material posture adjustment portion 91, allowing the material suction end 41 to smoothly pass through the material posture adjustment portion 91 in conjunction with the target material.

[0093] In some embodiments, the material to be assembled is located on a side of the fixed base 10 away from the material error platform 30, and the material adsorption end 41 cooperates with the target material to pass through the material posture adjustment part 91 to the position to be assembled, thereby realizing the assembly of the target material and the material to be assembled.

[0094] For example, in the production process of VR glasses including multiple rectangular magnets with a length, width and height of 3mm*0.8mm*0.6mm, the material adsorption end 41 cooperates with the first magnet to pass through the material posture adjustment part 91 to the first target position of the VR glasses mold. Afterwards, the material adsorption end 41 cooperates with the second magnet to pass through the material posture adjustment part 91 to the second target position of the VR glasses mold...., until a preset number of magnets are assembled into the VR glasses mold. Afterwards, the preset number of magnets are assembled as inserts in the VR glasses through injection molding. At this point, the assembly of the magnets in the VR glasses is completed.

[0095] Please refer to Figure 1 In an embodiment of the present application, the material conveying device also includes a loading positioning member 100, a first sensing device 110 and a controller, and the first sensing device 110 and the controller are electrically connected; the loading positioning member 100 is fixedly connected to the pressing rod 50, and when the pressing rod 50 moves toward the material inlet and outlet 22 to the extreme position, the loading positioning member 100 enters the position sensing area of ​​the first sensing device 110.

[0096] In some embodiments, the loading positioning member 100 moves in conjunction with the pressing rod 50 relative to the storage bin 20. When the number of target materials in the storage cavity 21 is at least one, the loading positioning member 100 moves away from the position sensing area of ​​the first sensing device 110. When the number of target materials in the storage cavity 21 is zero, the pressing rod 50 moves toward the material inlet and outlet 22 to its extreme position. At the same time, the loading positioning member 100 and the pressing rod 50 move in conjunction with each other to their extreme positions. At this time, the loading positioning member 100 enters the position sensing area of ​​the first sensing device 110, and the first sensing device 110 generates a sensing signal and transmits the sensing signal to the controller. The sensing signal indicates that the number of target materials in the storage cavity 21 is zero, which can be used as a loading prompt.

[0097] Specifically, the first sensing device 110 may be a position sensor.

[0098] In an embodiment of the present application, the material conveying device also includes a blanking positioning member 120 and a second sensing device 130, and the second sensing device 130 is electrically connected to the controller; the blanking positioning member 120 is fixedly connected to the pressing rod 50, and the second sensing device 130 is used to collect position change information of the blanking positioning member 120 and transmit the position change information to the controller, and the position change information indicates the change in the quantity of the target material in the storage bin 20.

[0099] Please refer to Figure 1 In some embodiments, the blanking positioning member 120 moves in coordination with the pressing rod 50 relative to the storage bin 20. During the process of the target material falling from the storage cavity 21 to the receiving position 32, the position of the pressing rod 50 relative to the storage bin 20 changes, and accordingly, the position of the blanking positioning member 120 that moves in coordination with the pressing rod 50 changes.

[0100] In some embodiments, the second sensing device 130 collects position change information of the blanking positioning member 120 and transmits the position change information to the controller. The controller receives the position change information of the blanking positioning member 120 and then controls the material misalignment platform 30 to move from the second position to the third position to achieve the conveyance of the target material from the material inlet and outlet 22 to the material suction end 41. In this way, the conveying efficiency of the target material is improved.

[0101] In some embodiments, the second sensing device 130 is fixed relative to the fixed base 10, and the second sensing device 130 can be a through-beam photoelectric sensor. The second sensing device 130 includes a transmitting end and a receiving end; the blanking positioning member 120 is arranged between the transmitting end and the receiving end, and the blanking positioning member 120 can be a light shielding sheet.

[0102] In some embodiments, the blanking positioning member 120 is provided with a plurality of light-transmitting holes, which are arranged equidistantly along the direction of motion of the push rod 50. The spacing between adjacent light-transmitting holes corresponds to the unit blanking height of the target material. Thus, the second sensing device 130 collects and outputs position change information for each unit blanking.

[0103] Specifically, the second sensing device 130 operates as follows: a transmitter emits red light or infrared light, which is received by a receiver. When the position of the blanking positioning member 120, which moves in conjunction with the press rod 50, changes, the blanking positioning member 120 cuts off the red light or infrared light emitted by the transmitter. At this point, the second sensing device 130 collects and outputs position change information about the blanking positioning member 120. This position change information indicates a change in the amount of target material within the storage bin 20, i.e., the target material has been dropped onto the receiving position 32.

[0104] In an embodiment of the present application, the material conveying device also includes a material error platform driving device 140, which is electrically connected to the controller; based on the driving signal generated by the controller, the material error platform driving device 140 can drive the material error platform 30 to move from the second position to the third position, and the driving signal is generated by the controller based on the position change information.

[0105] Please refer to Figure 1 In some embodiments, the controller receives the position change information transmitted by the second sensing device 130 and generates a driving signal based on the position change information; the material error platform driving device 140 drives the material error platform 30 from the second position to the third position based on the driving signal generated by the controller, so as to realize the transportation of the target material from the material inlet and outlet 22 to the material adsorption end 41.

[0106] In some embodiments, the working process of the material conveying device may include loading, dropping, transporting materials on the material transfer platform, retrieving materials, and transporting materials by the material suction part, as follows:

[0107] 1. Loading: Multiple target materials are pre-stacked and arranged, and then the pre-stacked multiple target materials are loaded into the storage cavity 21 through the loading port 31; after loading is completed, the blocking member 80 slides relative to the fixed base 10 until the blocking end 81 abuts against the target material arranged in the storage cavity 21 closest to the material inlet and outlet 22 to prevent the target material from falling from the loading port 31.

[0108] 2. Material dropping: When the material error platform 30 initially moves from the first position to the second position, the material blocking member 80 slides relative to the fixed base 10 until the material blocking end 81 slides relative to the fixed base 10 away from the material inlet and outlet 22, and the target material drops to the transition position 33; when the material error platform 30 slides to the second position relative to the fixed base 10, the target material drops to the receiving position 32.

[0109] 3. Material Misalignment Platform: When the second sensing device 130 detects position changes in the blanking positioning member 120, the controller controls the material misalignment platform drive device 140 to move the material misalignment platform 30 from the second position to the third position, in coordination with the target material. During this movement, the target material is limited and guided by the limiting pressure plate 60 and the stopper 70.

[0110] 5. Material removal: When the material misalignment platform 30 slides to the third position in coordination with the target material, the material adsorption end 41 adsorbs and removes the target material from the material receiving position 32 .

[0111] 6. Material transport by the suction member: The suction member 40 cooperates with the target material to pass through the material posture adjustment part 91 to the position to be assembled, so as to realize the assembly of the target material and the material to be assembled.

[0112] The material conveying device in the embodiment of the present application has the following beneficial effects:

[0113] 1. A storage bin that can accommodate multiple target materials is set up, and a material error platform with a loading port, a transition position and a material receiving position is set up. The material error platform can reciprocate between the storage bin and the material suction piece, which can significantly improve the conveying efficiency of the target materials and thus significantly improve the assembly efficiency of the target materials. The structure is simple and easy to debug.

[0114] 2. Setting the limit pressure plate, stop block and guide block to realize the limit guidance of the target material during the conveying process, which can improve the conveying accuracy of the target material and further improve the assembly accuracy of the target material.

[0115] 3. A loading positioning piece fixedly connected to the pressing rod and a first sensing device capable of sensing the movement of the loading positioning piece to the extreme position are provided, which can accurately determine the empty state of the storage cavity 21, and is conducive to realizing the automation of the target material loading.

[0116] 4. A blanking positioning piece fixedly connected to the pressing rod and a second sensing device capable of sensing the position change of the blanking positioning piece are provided, which can accurately judge the blanking situation of the target material, further improve the conveying efficiency of the target material, and thus improve the assembly efficiency of the target material.

[0117] The following describes specific embodiments of the present application based on the above technical solutions.

[0118] Example 1

[0119] See Figures 1 to 10, Example 1 provides a material conveying device, which includes a fixed base 10, a storage bin 20, a material error platform 30 and a material suction member 40; the storage bin 20 is fixedly connected to the fixed base 10, and the storage bin 20 is provided with a storage cavity 21, and the storage bin 20 is provided with a material inlet and outlet 22 at one end close to the fixed base 10, and the material inlet and outlet 22 is communicated with the storage cavity 21, and the storage cavity 21 can accommodate multiple target materials; the material error platform 30 is arranged between the storage bin 20 and the fixed base 10, and the material error platform 30 is slidably connected to the fixed base 10, and the material error platform 30 is provided with a loading port 31, when the material error platform 30 is relative to the fixed base When the fixed base 10 slides to the first position, the loading port 31 matches the position of the material inlet and outlet 22; the suction member 40 is arranged on the side of the material error platform 30 facing the storage bin 20, and the end of the suction member 40 close to the material error platform 30 is provided with a material adsorption end 41; the side of the material error platform 30 facing the storage bin 20 is provided with a material receiving position 32, and when the material error platform 30 slides to the second position relative to the fixed base 10, the material receiving position 32 matches the position of the material inlet and outlet 22, and when the material error platform 30 slides to the third position relative to the fixed base 10, the material receiving position 32 matches the position of the material adsorption end 41.

[0120] The storage bin 20 is disposed above the fixed base 10, and the storage cavity 21 is used to accommodate multiple target materials, and the material inlet and outlet 22 is used to allow multiple target materials to enter or exit the storage cavity 21. Specifically, the multiple target materials are stacked and arranged along the height direction of the target materials.

[0121] Before the target materials are loaded, they are pre-stacked and arranged by discharging them from the vibrating plate, and then loaded into the storage cavity 21 through the loading port 31. Loading refers to transferring the target materials into the storage cavity 21.

[0122] The loading port 31 extends through the material misalignment platform 30. When the material misalignment platform 30 is slid to its first position, the loading port 31 is located directly below the material inlet and outlet 22. Thus, the loading port 31 guides the target material into the material storage cavity 21, thereby improving the assembly accuracy of the target material. Furthermore, the placement of the loading port 31 on the material misalignment platform 30 reduces the structural complexity and size of the material conveying device.

[0123] The material conveying device also includes an air extraction device, which is provided with an air extraction end, which is connected to the material storage cavity 21. During the loading process of the multiple pre-stacked target materials, the air extraction device is simultaneously turned on. Under the action of the second power of the air extraction device, the air extraction end extracts air from the material storage cavity 21, so that the multiple pre-stacked target materials are better arranged in the material storage cavity 21, thereby ensuring smooth discharge of the target materials. When the loading of the multiple pre-stacked target materials is completed, the air extraction device is turned off. Here, discharge refers to the target materials falling from the material storage cavity 21.

[0124] The material conveying device includes a pressing rod 50, which is slidably connected to the storage bin 20; the pressing rod 50 is provided with a material pressing end 51, which is arranged in the storage cavity 21, and the pressing rod 50 can move toward or away from the material inlet and outlet 22.

[0125] The material pressing end 51 is provided at one end of the pressing rod 50 near the material inlet and outlet 22, and is inserted into the material storage cavity 21 for contacting the target material in the material storage cavity 21. Thus, under the action of the gravity of the pressing rod 50, the material pressing end 51 pushes the target material.

[0126] A slideway adapted to the pressing rod 50 is provided in the storage bin 20 , and the slideway is communicated with the storage cavity 21 . The pressing rod 50 slides in the slideway to achieve a sliding connection between the pressing rod 50 and the storage bin 20 .

[0127] The material conveying device also includes a material stopper 80, which is arranged on the side of the material inlet and outlet 22 and is slidably connected to the fixed base 10; the material stopper 80 can slide relative to the fixed base 10 until the position of the material stopper 80 matches the position of the material inlet and outlet 22.

[0128] A material stopping end 81 is provided at one end of the material stopping member 80 close to the material inlet and outlet 22. When multiple target materials are loaded, the material stopping member 80 slides relative to the fixed base 10 until the material stopping end 81 abuts against the target material arranged in the material storage cavity 21 closest to the material inlet and outlet 22 to prevent the target material from falling from the loading port 31.

[0129] The movement direction of the blocking end 81 is perpendicular to the movement direction of the target material; the blocking end 81 is inserted into the material storage cavity 21, and the structural surface of the blocking end 81 close to the material error platform 30 is aligned with the material inlet and outlet 22; the size of the blocking end 81 along the movement direction of the target material is consistent with the unit blanking height of the target material.

[0130] The material conveying device further includes a sliding seat, which is arranged on the side of the material inlet and outlet 22 and is fixedly connected to the fixed base 10 .

[0131] A second slide rail is provided in the sliding seat, and correspondingly, a second sliding portion that slides in the second slide rail is provided on the material blocking member 80, so that a guided sliding connection is achieved between the sliding seat and the material blocking member 80.

[0132] A first slide rail is provided on the fixed base 10 , and correspondingly, a first sliding portion that slides in the first slide rail is provided on the material error platform 30 , thereby realizing a guided sliding connection between the material error platform 30 and the fixed base 10 .

[0133] The material receiving position 32 is provided with a material receiving cavity capable of accommodating one target material. Specifically, during a unit material dropping process, only one target material drops into the material receiving cavity of the material receiving position 32 through the material inlet and outlet 22 .

[0134] When the material misalignment platform 30 slides to the second position, the material receiving position 32 can be located directly below the material inlet and outlet 22. In this way, the target material falls to the material receiving position 32 through the material inlet and outlet 22.

[0135] When the material handling platform 30 slides to the third position, the material receiving position 32 can be located directly below the material suction end 41. This allows the material suction end 41 to conveniently absorb the target material and remove the target material. Removal refers to the material suction end 41 sucking and removing the target material from the material receiving position 32.

[0136] A transition position 33 is provided on the side of the material misalignment platform 30 facing the material storage bin 20. The transition position 33 is higher than the material receiving position 32. The loading port 31 and the transition position 33 are arranged continuously in the sliding direction of the material misalignment platform 30 relative to the fixed base 10. The transition position 33 abuts the material inlet and outlet 22 during movement of the material misalignment platform 30 from the first position to the second position, and during reciprocating movement between the second and third positions.

[0137] When the material misalignment platform 30 slides to the second position relative to the fixed base 10 , the material receiving position 32 matches the position of the material inlet and outlet 22 , and thus the target material falls to the material receiving position 32 .

[0138] The height difference between the transition position 33 and the receiving position 32 is consistent with the unit blanking height of the target material. In this way, the blanking accuracy of the target material can be guaranteed, and then the assembly accuracy of the target material can be guaranteed.

[0139] The material conveying device also includes a blanking positioning member 120 and a second sensing device 130, and the second sensing device 130 is electrically connected to the controller; the blanking positioning member 120 is fixedly connected to the pressing rod 50, and the second sensing device 130 is used to collect the position change information of the blanking positioning member 120 and transmit the position change information to the controller. The position change information indicates the change in the quantity of the target material in the storage bin 20.

[0140] The second sensing device 130 is fixed relative to the fixed base 10. The second sensing device 130 is a through-beam photoelectric sensor. The second sensing device 130 includes a transmitting end and a receiving end. The blanking positioning member 120 is arranged between the transmitting end and the receiving end. The blanking positioning member 120 can be a light shielding sheet.

[0141] The blanking positioning member 120 is provided with multiple light-transmitting holes, which are arranged equidistantly along the direction of motion of the push rod 50. The spacing between adjacent light-transmitting holes corresponds to the unit blanking height of the target material. Thus, the second sensing device 130 collects and outputs position change information for each unit blanking.

[0142] The second sensing device 130 emits red light or infrared light at its transmitting end, and receives the red light or infrared light at its receiving end. When the position of the blanking positioning member 120, which moves in conjunction with the pressing rod 50, changes, the blanking positioning member 120 cuts off the red light or infrared light emitted by the transmitting end. At this time, the second sensing device 130 collects and outputs position change information of the blanking positioning member 120. The position change information indicates a change in the amount of target material in the storage bin 20, i.e., the target material has been dropped onto the receiving position 32.

[0143] The material conveying device also includes a material error platform driving device 140, which is electrically connected to the controller; based on the driving signal generated by the controller, the material error platform driving device 140 can drive the material error platform 30 to move from the second position to the third position, and the driving signal is generated by the controller based on the position change information.

[0144] The controller receives the position change information transmitted by the second sensing device 130 and generates a driving signal based on the position change information; the material error platform driving device 140 drives the material error platform 30 from the second position to the third position based on the driving signal generated by the controller, so as to realize the transportation of the target material from the material inlet and outlet 22 to the material adsorption end 41.

[0145] The material conveying device also includes a limiting pressure plate 60, which is arranged on the side of the material error platform 30 facing the storage bin 20; the limiting pressure plate 60 is fixedly connected to the fixed base 10, and a material limiting groove 61 is provided on the side of the limiting pressure plate 60 facing the material error platform 30.

[0146] The limiting pressure plate 60 is arranged above the material error platform 30, and the material limiting groove 61 is arranged toward the material error platform 30. An accommodating space capable of accommodating the target material is formed in the material limiting groove 61.

[0147] The limiting pressure plate 60 is a split structure, perpendicular to the movement direction of the material error platform 30, the limiting pressure plate 60 includes a left limiting pressure plate 62 and a right limiting pressure plate 63 that are arranged in conjunction with each other. The left limiting pressure plate 62 is provided with a left material limiting structure 64 on the side facing the material error platform 30, and the right limiting pressure plate 63 is provided with a right material limiting structure 65 on the side facing the material error platform 30. A material limiting groove 61 is formed between the left material limiting structure 64 and the right material limiting structure 65.

[0148] The material limiting groove 61 is a multi-step groove, which cooperates with the material error platform 30 and can accommodate the target material. In this way, in the process of the material error platform 30 coordinating the target material to move from the second position to the third position, the limiting guidance of the target material is realized.

[0149] A first inclined guide is provided at one end of the material stopper 61, near the material inlet and outlet 22. As the material misalignment platform 30 moves from the second position to the third position, the cross-sectional area of ​​the first inclined guide gradually decreases until it conforms to the target material. This first inclined guide accurately guides the target material into the material stopper 61, allowing the misalignment platform 30 and the target material to smoothly pass through the material stopper 61 to the third position.

[0150] The material conveying device further includes a stopper 70 , which is disposed on the end side of the material misalignment platform 30 . The stopper 70 is fixedly connected to the fixed base 10 , and is disposed toward the material receiving position 32 .

[0151] The stopper 70 is arranged on one side of the movement direction of the material error platform 30, and a material blocking end 71 is arranged at one end of the stopper 70 close to the material error platform 30. The material blocking end 71 is used to stop the target material to prevent the target material from being unable to be accurately maintained on the material receiving position 32 due to the action of inertia when the material error platform 30 cooperates with the target material to move to the third position.

[0152] The material conveying device also includes a power adsorption device 160. The material adsorption member 40 is fixedly connected to the top of the fixed base 10. The material adsorption member 40 is provided with a material adsorption end 41 and a suction end that are connected. The suction end is connected to the power adsorption device 160. Under the first power action of the power adsorption device 160, the material adsorption end 41 is used to adsorb or release the target material.

[0153] The material conveying device also includes a guide block 90, which is arranged below the material adsorption end 41 and is fixedly connected to the fixed base 10; the guide block 90 is provided with a material posture adjustment part 91, and the material adsorption end 41 can cooperate with the target material to pass through the material posture adjustment part 91.

[0154] Along the movement direction of the suction member 40, the material posture adjustment part 91 passes through the guide block 90, and the suction member 40 can cooperate with the target material to pass through the material posture adjustment part 91, thereby achieving the adjustment of the target material posture, which is beneficial to improving the assembly accuracy of the target material.

[0155] A second inclined guide is provided on the end of the material posture adjustment section 91 near the material misalignment platform 30. As the suction element 40 and the target material move through the material posture adjustment section 91, the cross-sectional area of ​​the second inclined guide gradually decreases until it conforms to the target material. This second inclined guide accurately guides the target material toward the material posture adjustment section 91, allowing the material suction end 41 to smoothly pass through the section 91.

[0156] The material to be assembled is located on the side of the fixed base 10 away from the material error platform 30. The material adsorption end 41 cooperates with the target material to pass through the material posture adjustment part 91 to the assembly position, thereby realizing the assembly of the target material and the material to be assembled.

[0157] The working process of the material conveying device in Example 1 may include loading, dropping, transporting on the material misalignment platform, taking out materials, and transporting materials by the material suction part, as follows:

Loading: Multiple target materials are pre-stacked and arranged, and then the pre-stacked multiple target materials are loaded into the storage cavity 21 through the loading port 31; after loading is completed, the blocking member 80 slides relative to the fixed base 10 until the blocking end 81 abuts against the target material arranged in the storage cavity 21 closest to the material inlet and outlet 22 to prevent the target material from falling from the loading port 31.

[0159] 2. Material dropping: When the material error platform 30 initially moves from the first position to the second position, the material blocking member 80 slides relative to the fixed base 10 until the material blocking end 81 slides relative to the fixed base 10 away from the material inlet and outlet 22, and the target material drops to the transition position 33; when the material error platform 30 slides to the second position relative to the fixed base 10, the target material drops to the receiving position 32.

[0160] 3. Material Misalignment Platform: When the second sensing device 130 detects position changes in the blanking positioning member 120, the controller controls the material misalignment platform drive device 140 to move the material misalignment platform 30 from the second position to the third position, in coordination with the target material. During this movement, the target material is limited and guided by the limiting pressure plate 60 and the stopper 70.

[0161] 5. Material removal: When the material misalignment platform 30 slides to the third position in coordination with the target material, the material adsorption end 41 adsorbs and removes the target material from the material receiving position 32 .

[0162] 6. Material transport by the suction member: The suction member 40 cooperates with the target material to pass through the material posture adjustment part 91 to the position to be assembled.

[0163] The material conveying device in Example 1 has the following beneficial effects:

[0164] 1. A storage bin that can accommodate multiple target materials is set up, and a material error platform with a loading port, a transition position and a material receiving position is set up. The material error platform can reciprocate between the storage bin and the material suction piece, which can significantly improve the conveying efficiency of the target materials and thus significantly improve the assembly efficiency of the target materials. The structure is simple and easy to debug.

[0165] 2. Setting the limit pressure plate, stop block and guide block to realize the limit guidance of the target material during the conveying process, which can improve the conveying accuracy of the target material and further improve the assembly accuracy of the target material.

[0166] 3.

[0167] Example 2

[0168] See Figures 1 to 10 The difference between Example 2 and Example 1 lies in the arrangement of the loading positioning member, the first sensing device and the limiting pressure plate 60. The similarities between Example 2 and Example 1 will not be repeated here, and only the differences between Example 2 and Example 1 will be described.

[0169] The material conveying device also includes a loading positioning member 100, a first sensing device 110 and a controller, and the first sensing device 110 and the controller are electrically connected; the loading positioning member 100 is fixedly connected to the pressing rod 50, and when the pressing rod 50 moves toward the material inlet and outlet 22 to the extreme position, the loading positioning member 100 enters the position sensing area of ​​the first sensing device 110.

[0170] The loading positioning member 100 moves in conjunction with the pressing rod 50 relative to the storage bin 20. When the number of target materials in the storage cavity 21 is at least one, the loading positioning member 100 moves away from the position sensing area of ​​the first sensing device 110. When the number of target materials in the storage cavity 21 is zero, the pressing rod 50 moves toward the material inlet and outlet 22 to its extreme position. At the same time, the loading positioning member 100 and the pressing rod 50 move in conjunction with each other to their extreme positions. At this time, the loading positioning member 100 enters the position sensing area of ​​the first sensing device 110, and the first sensing device 110 generates a sensing signal and transmits the sensing signal to the controller. The sensing signal indicates that the number of target materials in the storage cavity 21 is zero, which can be used as a feeding prompt.
