Description

Technical Field

[0001] This disclosure relates to a feeding system, belonging to the field of automation equipment technology. Background Technology

[0002] With technological advancements, more and more factories are adopting automated equipment to manufacture products. This is especially true in the production of 3C products, where automated equipment has become widespread.

[0003] In the process of product manufacturing by automated equipment, the material loading and unloading structure is a crucial factor affecting the production line's cycle time. For example, when loading via pallets, there may be empty spaces in the pallets, which reduces the processing efficiency of the automated production line and may even cause subsequent equipment to malfunction.

[0004] In existing technologies, during pallet loading, the completeness of materials on the pallet is manually checked. If any materials are missing, they are manually replenished. However, manual operation carries a certain probability of error, which affects the processing efficiency of automated production lines.

[0005] Chinese utility model patent CN220879620U discloses a PCBA board insertion detection and replenishment device, but this structure is not suitable for replenishing materials in trays on the production line.

[0161] The present disclosure 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 for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0162] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0163] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0164] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0165] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0166] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0167] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0168] Figure 1 This is a schematic diagram of a feeding system according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the internal structure of a feeding system according to one embodiment of the present disclosure.

[0169] like Figure 1 and Figure 2As shown, the replenishment system disclosed herein can replenish missing materials in the pallet during use, so that the pallet is in a full state.

[0170] Specifically, the feeding system of this disclosure may include a frame structure, which may include a lower frame structure and an upper frame structure disposed on the lower frame structure. The conveying device 300, camera device 200, handling device 700, and feeding device 800, etc., described below, are all disposed within the frame structure. The frame structure of this disclosure includes a length direction and a width direction, wherein the length direction can be defined as a first direction, and the width direction can be defined as a second direction.

[0171] like Figure 1 and Figure 2 As shown, the feeding system disclosed herein may also include components such as a camera device 200, a conveying device 300, a handling device 700, and a feeding device 800.

[0172] The conveying device 300 of this disclosure is used to convey pallets containing materials; specifically, the materials loaded in the pallets are the same. In one specific embodiment, the replenishment system can be installed in an automated production line, in which case the conveying device 300 can be connected to the automated production line to receive pallets conveyed by the automated production line, and when the materials in the pallets are replenished, the conveying device 300 can convey the pallets to the automated production line, where the pallets will continue to flow on the automated production line.

[0173] Figure 3 This is a schematic diagram of the structure of a conveying device according to one embodiment of the present disclosure. Figure 4 This is a structural schematic diagram of a conveying device according to one embodiment of the present disclosure from another angle. Figure 5 This is a structural schematic diagram of a portion of the conveying device according to one embodiment of the present disclosure. Figure 6 This is a structural schematic diagram of a portion of the conveying device according to one embodiment of the present disclosure from another angle.

[0174] like Figures 3 to 6 As shown, the conveying device 300 of this disclosure includes components such as a conveying base plate 310, a first supporting side plate 320, a second supporting side plate 330, a first conveying assembly 340, a second conveying assembly 350, and a first driving assembly 360.

[0175] The conveying base plate 310 of this disclosure is generally square in shape, with its length direction being the second direction described above and its width direction being the first direction described above. That is, the conveying device 300 of this disclosure is capable of conveying pallets along the second direction. In a specific embodiment, the conveying base plate 310 of this disclosure is fixed to a frame structure.

[0176] Both the first support side plate 320 and the second support side plate 330 are slidably disposed on the conveying base plate 310. Specifically, the conveying base plate 310 is provided with two guide rails, which are arranged in parallel and both are arranged along a first direction.

[0177] One end of the first support side plate 320 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Similarly, one end of the second support side plate 330 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Thus, both the first support side plate 320 and the second support side plate 330 can slide on the guide rails, allowing them to approach or move away from each other in a first direction.

[0178] With the above structure, the length direction of the first support side plate 320 and the second support side plate 330 of this disclosure is parallel to the second direction.

[0179] In this disclosure, when the first support side plate 320 and the second support side plate 330 approach or move away from each other, one of the first support side plate 320 and the second support side plate 330 can remain stationary. In a preferred embodiment, the first support side plate 320 and the second support side plate 330 can move in opposite directions simultaneously, so that the first support side plate 320 and the second support side plate 330 can approach or move away from each other.

[0180] The first conveying assembly 340 is disposed on the first support side plate 320 and located inside the first support side plate 320; similarly, the second conveying assembly 350 is disposed on the second support side plate 330 and located inside the second support side plate 330. That is, the first conveying assembly 340 and the second conveying assembly 350 of this disclosure are located in the area between the first support side plate 320 and the second support side plate 330, thereby enabling the conveying of a pallet via the first conveying assembly 340 and the second conveying assembly 350. In other words, a pallet loaded with material can be placed on the first conveying assembly 340 and the second conveying assembly 350 and conveyed by them.

[0181] The first drive assembly 360 is used to drive the first support side plate 320 and / or the second support side plate 330 to move, so that the first support side plate 320 and the second support side plate 330 can approach or move away from each other. Thus, the conveying device of this disclosure can be adapted to pallets of different sizes. That is, the width between the first support side plate 320 and the second support side plate 330 of this disclosure can change with the size of the pallet, so that the conveying device 300 of this disclosure can convey pallets of different sizes, thereby achieving compatibility with pallets of different sizes.

[0182] The first drive assembly 360 of this disclosure can simultaneously drive the first support side plate 320 and the second support side plate 330, and cause the first support side plate 320 and the second support side plate 330 to have opposite directions of movement.

[0183] Specifically, the first drive assembly 360 of this disclosure may include a first drive motor and a first bidirectional spiral screw 361 driven to rotate by the first drive motor. The first bidirectional spiral screw 361 may be a trapezoidal screw with both positive and negative teeth. Specifically, the first drive motor is fixed to the conveying base plate 310; both ends of the first bidirectional spiral screw 361 are rotatably disposed on the conveying base plate 310 through bearing seats, and the axis of the first bidirectional spiral screw 361 is disposed along a first direction. At this time, the bearing seats can limit the axial position of the first bidirectional spiral screw 361.

[0184] A first nut is provided on the first support side plate 320, and a second nut is provided on the second support side plate 330. The first nut and the second nut have different helical directions, and both the first nut and the second nut cooperate with the first bidirectional helical screw 361. Thus, when the first bidirectional helical screw 361 rotates in one direction, the first support side plate 320 and the second support side plate 330 can approach each other, and when the first bidirectional helical screw 361 rotates in another direction, the first support side plate 320 and the second support side plate 330 can move away from each other.

[0185] Both the first conveying assembly 340 and the second conveying assembly 350 are synchronous belt conveying assemblies, thereby enabling the conveying of pallets disposed on the synchronous belt through the movement of the synchronous belt of the synchronous belt conveying assembly. In this disclosure, the first conveying assembly 340 includes a first driving pulley and at least one first driven pulley, which are connected by a first synchronous belt drive; similarly, the second conveying assembly 350 includes a second driving pulley and at least one second driven pulley, which are connected by a second synchronous belt drive.

[0186] The conveying device 300 disclosed herein further includes a second drive component 370, which is used to drive the first conveying component 340 and the second conveying component 350 to move; that is, the second drive component 370 of this disclosure is set to one, and the first conveying component 340 and the second conveying component 350 are synchronously driven through the second drive component 370.

[0187] The second drive assembly 370 includes a second drive motor and a conveying drive shaft 371 driven by the second drive motor. The cross-section of the conveying drive shaft 371 is non-circular, for example, hexagonal. Both the first drive wheel and the second drive wheel are slidably disposed on the conveying drive shaft 371 and are driven by the conveying drive shaft 371 to rotate.

[0188] Specifically, the two ends of the conveying drive shaft 371 disclosed herein are rotatably supported on the conveying base plate 310 by bearing seats, and the axial position of the conveying drive shaft 371 can be restricted by the bearing seats. That is to say, the axis of the conveying drive shaft 371 is set along the first direction and will not move along the first direction.

[0189] The first drive wheel is rotatably supported on the first support side plate 320 via a bearing, and the conveying drive shaft 371 can slide within the inner hole of the bearing, so that the conveying drive shaft 371 does not affect the movement of the first support side plate 320 in the first direction. Similarly, the second drive wheel is rotatably supported on the second support side plate 330 via a bearing, and the conveying drive shaft 371 can slide within the inner hole of the bearing, so that the conveying drive shaft 371 does not affect the movement of the second support side plate 330 in the first direction.

[0190] The conveying device 300 disclosed herein also includes a conveying lifting assembly 380, which drives a pad 390 between a first support side plate 320 and a second support side plate 330 to rise or fall, thereby causing the pallet carried on the pad 390 to rise or fall.

[0191] Specifically, the upper surface of the first synchronous belt of this disclosure can be formed into a discontinuous structure by means of a reversing wheel. Similarly, the upper surface of the second synchronous belt can also be formed into a discontinuous structure. Thus, at least a portion of the pad 390 can move through the gap between the upper surfaces of the first and second synchronous belts to below the upper surfaces of the first and second synchronous belts. At this position, the pad 390 will not affect the movement of the pallet on the conveyor 300.

[0192] The conveying device 300 disclosed herein may further include a blocking device, which may include a lifting cylinder and a blocking plate driven by the lifting cylinder. When the lifting cylinder is in the rising position, the blocking plate can block the pallets conveyed by the first conveying component 340 and the second conveying component 350. When the lifting cylinder is in the falling position, the blocking plate will not block the movement of the pallets.

[0193] Thus, the pallet can be blocked by the blocking device and positioned directly above the pad 390. Next, when the pad 390 rises, it allows the pallet to rise, and the risen pallet can be easily moved by the conveying device 700 described below.

[0194] In one embodiment, not all pallets are handled by the handling device; most pallets remain at the conveyor 300 and are replenished with materials.

[0195] like Figure 2 As shown, the camera device 200 of this disclosure is used to photograph the pallet. In a preferred embodiment, a reflector is mounted on the frame structure, and the camera device 200 captures an image of the pallet at the conveyor device 300 via the reflector, and determines whether there is a shortage of material in the pallet based on the image. When there is a shortage of material in the pallet, the specific location of the shortage can also be obtained based on the image of the pallet, so as to facilitate the replenishment of material by components such as the material handling system described below.

Figure 8 This is a structural schematic diagram of a conveying device 700 according to one embodiment of the present disclosure. Figure 9 and Figure 10 These are structural schematic diagrams of a conveying device 700 according to one embodiment of the present disclosure from different angles.

[0197] like Figures 8 to 10 As shown, when in use, the conveying device 700 of this disclosure is used to transport the pallet conveyed by the conveying device 300 to the buffer device 400. In addition, when the conveying device 700 of this disclosure includes a redundant support device 790, the conveying device 700 can also transport the pallet to the redundant support device 790.

[0198] Specifically, the conveying device 700 disclosed herein includes components such as a first support assembly 710, a second support assembly 720, a crossbeam 730, a first drive device 740, a Z-axis motion platform 750, a connecting plate 760, and a material picking plate 770.

[0199] The first support component 710 has a length direction, which can be horizontal, such as the first direction described above; the second support component 720 is arranged parallel to the first support component 710. That is, the conveying direction of the conveying device 700 of this disclosure is perpendicular to the conveying direction of the conveying device 300.

[0200] One end of the crossbeam 730 is slidably disposed on the first support assembly 710, and the other end of the crossbeam 730 is slidably disposed on the second support assembly 720; the first driving device 740 is used to drive the crossbeam 730 to slide relative to the first support assembly 710 and the second support assembly 720.

[0201] Specifically, the first support assembly 710 disclosed herein includes components such as a first support column 711, a first support beam 712, a first guide rail 713, a second guide rail 714, a first slider 715, and a second slider 716.

[0202] Multiple first support columns 711 are provided along the length of the first support assembly 710; specifically, three first support columns 711 are provided. The first support columns 711 are fixed to the frame structure, and the first support beam 712 is provided at the upper end of the first support columns 711; the length direction of the first support beam 712 is the same as the length direction of the first support assembly 710.

[0203] A first guide rail 713 is disposed on a first support beam 712, and the length direction of the first guide rail 713 is the same as the length direction of the first support beam 712. A second guide rail 714 is disposed on the first support beam 712, and the second guide rail 714 is disposed parallel to the first guide rail 713, with a predetermined distance between the first guide rail 713 and the second guide rail 714. In addition, a through hole is provided on the first support beam 712, which extends along the length direction of the first support beam 712 and is located directly below the gap between the first guide rail 713 and the second guide rail 714.

[0204] One end of the crossbeam 730 is provided with a first slider 715 and a second slider 716. The first slider 715 is slidably disposed on the first guide rail 713, and the second slider 716 is slidably disposed on the second guide rail 714.

[0205] Thus, by providing a first slider 715 and a second slider 716 at one end of the crossbeam 730, the crossbeam 730 can be guided by the first slider 715 and the second slider 716 and slide stably along the length direction of the first support beam 712.

[0206] In a preferred embodiment, two first sliders 715 and two second sliders 716 are provided, thereby the crossbeam 730 of this disclosure can be stably supported by the two first sliders 715 and the two second sliders 716.

[0207] like Figure 10 As shown, the first driving device 740 of this disclosure is a motor-driven lead screw and nut structure. Moreover, the first driving device 740 is located below the first support beam 712. The nut of the first driving device 740 passes through the first support beam 712 and is fixed to the crossbeam 730. That is to say, at least a portion of the nut of the first driving device 740 of this disclosure is located in the through hole of the first support beam 712 and can slide in the through hole. Thus, the crossbeam 730 of this disclosure can move stably without getting stuck.

[0208] Since the structure of the lead screw and nut driven by the motor is a common structure in the field, this disclosure will not describe this structure in detail.

[0209] See again Figure 8 and Figure 9 The second support assembly 720 disclosed herein includes components such as a second support column 721, a second support beam 722, a third guide rail 723, and a third slider 724.

[0210] Multiple second support columns 721 are provided along the length of the second support assembly 720; specifically, three second support columns 721 are provided, and these three second support columns 721 are provided along the length of the second support assembly 720. The second support columns 721 are fixed to the frame structure, and the second support beam 722 is provided at the upper end of the second support columns 721; the length direction of the second support beam 722 is the same as the length direction of the second support assembly 720.

[0211] The third guide rail 723 is disposed on the second support beam 722, and the length direction of the third guide rail 723 is the same as the length direction of the second support beam 722; the other end of the crossbeam 730 is provided with a third slider 724, which is slidably disposed on the third guide rail 723.

[0212] Therefore, the third slider 724 of this disclosure can support the crossbeam 730 without causing it to overturn. In a preferred embodiment, the number of the third slider 724 can also be set to two.

[0213] Figure 11 This is a schematic diagram of the material handling plate of a conveying device according to one embodiment of the present disclosure. Figure 12 This is a structural schematic diagram of the material handling plate of a conveying device according to one embodiment of the present disclosure from another angle.

[0214] like Figure 11 and Figure 12As shown, the Z-axis motion platform 750 of this disclosure is disposed on the crossbeam 730; the connecting plate 760 is disposed on the Z-axis motion platform 750 so as to drive the connecting plate 760 to rise and fall through the Z-axis motion platform 750; the picking plate 770 is fixed to the connecting plate 760, wherein the picking plate 770 is provided with a plurality of conveying suction cups 780.

[0215] In this disclosure, the Z-axis motion platform 750 can be a motor-driven lead screw and nut structure, and the Z-axis motion platform 750 is fixed at approximately the middle position of the crossbeam 730.

[0216] The material handling plate 770 has multiple elongated holes arranged in multiple rows and columns, with the length directions of the elongated holes in different columns parallel; the elongated holes in adjacent columns are staggered. Therefore, the conveying suction cup 780 of this disclosure can be installed in different elongated holes, or at different positions within a single elongated hole, making the position of the conveying suction cup 780 adjustable. Accordingly, the conveying device 700 of this disclosure can be adapted to pallets of different shapes and sizes.

[0217] Figure 13 This is a schematic diagram of the structure of a redundant support device of a conveying apparatus according to one embodiment of the present disclosure.

[0218] The handling device 700 of this disclosure also includes a redundant support device 790 for carrying pallets. Specifically, the handling device 700 is used to move pallets conveyed by the conveyor 300 to the redundant support device 790. For example, the handling suction cup 780 of the handling device 700 can pick up the pallet on the conveyor 300 and move the pallet to the redundant support device 790.

[0219] In other words, when the replenishment system of this disclosure is in use, the handling device 700 first moves one pallet loaded with material at the conveying device 300 to the redundant bearing device 790; then, it moves another pallet loaded with material at the conveying device 300 to the buffer device 400; thus, the replenishment system of this disclosure includes two pallets for replenishment. Accordingly, when a pallet at the conveying device 300 needs replenishment, material can be taken out from one pallet and replenished; when all the material in the pallet has been used for replenishment, the empty pallet will be unloaded; then material can be taken out from the other pallet and replenished.

[0220] Once the current material replenishment is completed, the handling device 700 can move the next pallet conveyed by the conveying device 300 to the buffer device 400 or the redundant support device 790, so that there is always a pallet loaded with materials on the buffer device 400 and the redundant support device 790.

[0221] In one specific embodiment, the redundant support device 790 includes structures such as a first upright plate 791, a second upright plate 792, a second drive device 793, and a second support platform 794.

[0222] The first upright plate 791 is fixed to the first support component 710; the second upright plate 792 is fixed to the second support component 720. Specifically, the first upright plate 791 and the second upright plate 792 of this disclosure are both formed as plate-shaped structures and are set approximately vertically. At this time, the first upright plate 791 and the second upright plate 792 can be parallel to each other.

[0223] The first upright plate 791 can be fixed to the first support column 711, and the second upright plate 792 can be fixed to the second support column 721. Moreover, the length direction of the first upright plate 791 and the length direction of the second upright plate 792 are both parallel to the length direction of the first support component 710.

[0224] The second drive device 793 is disposed on the first upright plate 791. In a specific embodiment, the second drive device 793 is also a motor-driven lead screw and nut structure, and the second drive device 793 is located on the side of the first upright plate 791. One end of the second support platform 794 is fixed to the second drive device 793, that is, one end of the second support platform 794 can be fixed to the nut of the second drive device 793, and the other end of the second support platform 794 is slidably disposed on the second upright plate 792.

[0225] In addition, a fourth guide rail 795 is provided on the second upright plate 792, and a fourth slider 796 is fixed at the other end of the second support platform 794. The fourth slider 796 is slidably disposed on the fourth guide rail 795, thereby enabling the second support platform 794 of this disclosure to move along the length direction of the first support component 710.

[0226] Thus, the second support platform 794 of this disclosure can be used to support a tray, and the second support platform 794 can move so that the second support platform 794 and the buffer device 400 can be in different positions.

[0227] Figure 14 This is a schematic diagram of the structure of a cache device according to one embodiment of the present disclosure.

[0228] like Figure 14 As shown, the buffer device 400 of this disclosure includes a drive module 410 and a first support platform 420 disposed on the drive module 410. The drive module 410 is directly or indirectly disposed on the frame structure and is used to drive the first support platform 420 to rise or fall. In a specific embodiment, the drive module 410 of this disclosure can be a cylinder or a lead screw motor, etc.

[0229] Therefore, the buffer device 400 of this disclosure can lower the pallet supported on the first support platform 420, thereby allowing the second support platform to move above the first support platform, so that the second support platform no longer obstructs the upper end of the hopper device 100. At this time, an empty pallet can be placed into the hopper, and the empty pallet can be unloaded.

[0230] Figure 15 This is a schematic diagram of the structure of a feeding device 800 according to one embodiment of the present disclosure.

[0231] The replenishing device 800 disclosed herein is used to replenish materials in a pallet at a buffer device 400 to a pallet at a conveying device 300. Furthermore, the replenishing device 800 is also used to replenish materials in a pallet carried by a redundant carrying device to a pallet at a conveying device 300.

[0232] The feeding device 800 disclosed herein may include components such as a motion platform 810, a pitch control device 820, and a feeding module 830.

[0233] The motion platform 810 is mounted on the crossbeam 730 and is configured to move along a second direction; wherein, the second direction can be horizontal, in which case the crossbeam 730 is also positioned along the second direction. In a specific embodiment, the motion platform 810 is a motor-driven lead screw and nut structure. Since the motor-driven lead screw and nut structure is a common structure in the art, its structure will not be described in detail here.

[0234] The pitch-changing device 820 is disposed on the motion platform 810, and the motion platform 810 drives the pitch-changing device 820 to reciprocate along the second direction; thus, when the feeding device 800 of this disclosure is used, it can not only change the distance between materials, but also make the materials move as a whole along the second direction.

[0235] In one specific embodiment, the pitch control device 820 is a motor-driven cam pitch control mechanism.

[0236] Figure 17 This is a schematic diagram of the motion platform and pitch device of a feeding device according to one embodiment of the present disclosure. Figure 18 This is a structural schematic diagram of the motion platform and pitch device of a feeding device according to one embodiment of the present disclosure from another angle.

[0237] like Figure 17 and Figure 18As shown, the pitch-changing device 820 of this disclosure includes a housing 821, on which a plurality of fifth guide rails 822 are provided, wherein the plurality of fifth guide rails 822 are all arranged along a second direction. Specifically, one surface of the housing 821 of this disclosure is arranged substantially vertically, and a through hole is formed on this surface, the through hole extending along the second direction. At the same time, the camshaft of the pitch-changing device 820 also extends along the second direction, and the camshaft corresponds to the through hole in the height direction.

[0238] The pitch control device 820 disclosed herein also includes a pitch block 823, wherein the pitch block 823 can be driven by a camshaft to change the distance in a second direction. That is, at least a portion of the pitch block 823 can be inserted into the interior of the housing 821 via a through hole, thereby allowing the portion of the pitch block 823 located within the housing 821 to slide within a cam groove on the camshaft, thus enabling the pitch block 823 to change position in the second direction.

[0239] See again Figure 15 The material replenishment module 830 of this disclosure is configured as a plurality of modules, wherein the pitch changer 820 is used to drive the plurality of material replenishment modules 830 to operate so that the distance between adjacent material replenishment modules 830 can be changed.

[0240] In other words, the number of pitch blocks 823 disclosed herein can be the same as the number of feeding modules 830 and they can be set one-to-one. Thus, when the pitch blocks 823 move in the second direction, the feeding modules 830 can move in the second direction.

[0241] The replenishment module 830 is provided with a slider 824; specifically, the replenishment module 830 of this disclosure is not directly connected to the slider 824, but is indirectly connected to the slider 824. For example, the replenishment module 830 can be connected to the pitch block 823 via the first connector 840, which is connected to the slider 824, wherein each pitch block 823 is provided with two sliders 824.

[0242] In this disclosure, the sliders 824 of adjacent replenishment modules 830 are slidably disposed on different fifth guide rails 822. The slider 824 of the replenishment module 830 refers to the slider 824 corresponding to that replenishment module 830.

[0243] Specifically, the fifth guide rail 822 includes a first fifth guide rail, a second fifth guide rail, a third fifth guide rail, and a fourth fifth guide rail; the first fifth guide rail, the second fifth guide rail, the third fifth guide rail, and the fourth fifth guide rail are arranged sequentially from top to bottom and distributed at equal intervals.

[0244] In this disclosure, each replenishment module 830 is provided with two sliders 824, that is, each replenishment module 830 corresponds to two sliders. Among them, along the second direction, the replenishment modules 830 located at odd-numbered positions (i.e., along the second direction) are... Figure 15 Two sliders 824 (from left to right) are slidably mounted on the first and fifth guide rails and the third and fifth guide rails, respectively; the feeding module 830 (located at an even-numbered position) Figure 15 The two sliders 824 (from left to right) are slidably set on the second and fifth guide rails and the fourth and fifth guide rails, respectively.

[0245] Therefore, the sliders 824 of two adjacent feeding modules 830 will not interfere with each other, and the two feeding modules 830 can be brought close together. At this time, the feeding device 800 can be used for closely arranged materials.

[0246] Figure 19 This is a schematic diagram of the structure of a feeding module of a feeding device according to one embodiment of the present disclosure. Figure 20 and Figure 21 This is a structural schematic diagram of the feeding module of a feeding device according to one embodiment of the present disclosure from another angle.

[0247] like Figures 19 to 21 As shown, in one embodiment, the first connector 840 corresponding to the even-numbered feeding module 830 is connected to the second connector 850, and the second connector 850 is guided by the guide rod 860.

[0248] Specifically, the second connector 850 of this disclosure has guide holes, through which the guide rod 860 passes, allowing the second connector 850 to slide along the guide rod 860. As a result, the feeding module 830 located at an even-numbered position of this disclosure has higher precision during movement.

[0249] The second connector 850 of this disclosure is formed in a generally L-shaped structure, that is, it includes a horizontal section and a vertical section that are vertically connected. The other end of the horizontal section is connected to the upper end of the first connector 840. The replenishing module 830 is fixed to the vertical section and is located in the space enclosed by the first connector and the second connector.

[0250] In a preferred embodiment, the feeding module 830 is fixedly connected to the second connector 850, thereby enabling the feeding module 830 of this disclosure to maintain a firm fixed relationship with the pitch block 823.

[0251] See again Figures 19 to 21The feeding module 830 of this disclosure includes an output shaft 831, which is capable of rotation and lifting relative to the first connector 840. In other words, the feeding module 830 of this disclosure can be formed as a ZR module (or referred to as a ZR shaft), and the rotational and lifting degrees of freedom of the feeding module 830 can be independent degrees of freedom.

[0252] A mounting plate 832 is fixed on the output shaft 831 of this disclosure. A feeding suction cup 833 and a positioning post 834 are fixed on the lower surface of the mounting plate 832. Thus, the feeding device 800 of this disclosure can pick up materials through the feeding suction cup 833 and limit the distance between the materials and the mounting plate 832 through the positioning post 834, thereby achieving material positioning.

[0253] In one embodiment, the housing 821 of the pitch converter 820 of this disclosure is disposed on the connecting plate 870, and the connecting plate 870 is fixedly connected to the nut of the motion platform 810. Since the motion platform 810 can drive the pitch converter 820 to move along a preset horizontal direction (second direction).

[0254] Figure 23 This is a structural schematic diagram of a silo device according to one embodiment of the present disclosure. Figures 24 to 28 These are structural schematic diagrams of a silo device according to one embodiment of the present disclosure from different angles.

[0255] like Figures 23 to 28 As shown, the hopper device 100 disclosed herein may include: a hopper bottom plate 110, a first support plate 120, a second support plate 130, a first hopper conveying assembly 140, a second hopper conveying assembly 150, and a first hopper drive assembly 160, etc.

[0256] The hopper bottom plate 110 disclosed herein is generally square in shape and is fixed to the frame structure; the first support plate 120 and the second support plate 130 are both slidably disposed on the hopper bottom plate 110. Specifically, the hopper bottom plate 110 is provided with two guide rails, which are arranged in parallel and both are arranged along a second direction.

[0257] One end of the first support plate 120 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Similarly, one end of the second support plate 130 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Thus, both the first support plate 120 and the second support plate 130 can slide on the guide rails, allowing them to approach or move away from each other in a second direction.

[0258] With the above structure, the length direction of the first support plate 120 and the second support plate 130 of this disclosure is parallel to the first direction.

[0259] In this disclosure, when the first support plate 120 and the second support plate 130 approach or move away from each other, one of the first support plate 120 and the second support plate 130 can remain stationary. In a preferred embodiment, the first support plate 120 and the second support plate 130 can move in opposite directions simultaneously, so that the first support plate 120 and the second support plate 130 can approach or move away from each other.

[0260] The first hopper conveying assembly 140 is disposed on the first support plate 120 and located inside the first support plate 120; similarly, the second hopper conveying assembly 150 is disposed on the second support plate 130 and located inside the second support plate 130. That is, the first hopper conveying assembly 140 and the second hopper conveying assembly 150 of this disclosure are located in the area between the first support plate 120 and the second support plate 130, thereby enabling the conveying of pallets (i.e., empty pallets) via the first hopper conveying assembly 140 and the second hopper conveying assembly 150. In other words, at this time, a stack of empty pallets (i.e., at least one stack of empty pallets) can be placed on the first hopper conveying assembly 140 and the second hopper conveying assembly 150 and conveyed outward by the first hopper conveying assembly 140 and the second hopper conveying assembly 150.

[0261] The first hopper drive assembly 160 is used to drive the first support plate 120 and / or the second support plate 130 to move, so that the first support plate 120 and the second support plate 130 can approach or move away from each other. Thus, the hopper device of this disclosure can adapt to pallets of different sizes. That is, the width between the first support plate 120 and the second support plate 130 of this disclosure can change with the size of the pallet, so that the hopper device 100 of this disclosure can transport pallets of different sizes, thereby achieving compatibility with pallets of different sizes.

[0262] Specifically, the first hopper drive assembly 160 of this disclosure can simultaneously drive the first support plate 120 and the second support plate 130, and make the first support plate 120 and the second support plate 130 have opposite directions of movement.

[0263] Specifically, the first hopper drive assembly 160 of this disclosure may include a first drive motor and a second bidirectional spiral screw 161 driven to rotate by the first drive motor. The second bidirectional spiral screw 161 may be a trapezoidal screw with both positive and negative threads. Specifically, the first drive motor is fixed to the hopper bottom plate 110; both ends of the second bidirectional spiral screw 161 are rotatably disposed on the hopper bottom plate 110 through bearing seats, and the axis of the second bidirectional spiral screw 161 is arranged along a second direction. At this time, the bearing seats can limit the axial position of the second bidirectional spiral screw 161.

[0264] A first nut is provided on the first support plate 120, and a second nut is provided on the second support plate 130. The first nut and the second nut have different helical directions, and both the first nut and the second nut cooperate with the second bidirectional helical screw. Thus, when the second bidirectional helical screw 161 rotates in one direction, the first support plate 120 and the second support plate 130 can approach each other, and when the second bidirectional helical screw 161 rotates in another direction, the first support plate 120 and the second support plate 130 can move away from each other.

[0265] Both the first hopper conveyor assembly 140 and the second hopper conveyor assembly 150 are synchronous belt conveyor assemblies, thereby enabling the conveying of pallets disposed on the synchronous belt through the movement of the synchronous belt of the synchronous belt conveyor assembly. In this disclosure, the first hopper conveyor assembly 140 includes a first driving pulley 141 and at least one first driven pulley, which are connected by a first synchronous belt drive. Similarly, the second hopper conveyor assembly 150 includes a second driving pulley 151 and at least one second driven pulley, which are connected by a second synchronous belt drive. Since synchronous belt conveyor assemblies are common structures in the art, their structure will not be described in detail in this disclosure.

[0266] The hopper device 100 disclosed herein further includes a second hopper drive assembly 170, which is used to drive the first hopper conveying assembly 140 and the second hopper conveying assembly 150 to move; that is, the second hopper drive assembly 170 of this disclosure is set to one, and the first hopper conveying assembly 140 and the second hopper conveying assembly 150 are synchronously driven through the second hopper drive assembly 170.

[0267] The second hopper drive assembly 170 includes a second drive motor and a drive shaft 171 driven by the second drive motor. The cross-section of the drive shaft 171 is non-circular, for example, hexagonal. The first drive wheel 141 and the second drive wheel 151 are both slidably disposed on the drive shaft 171 and driven by the drive shaft 171 to rotate.

[0268] Specifically, the two ends of the drive shaft 171 of this disclosure are rotatably supported on the bottom plate 110 of the hopper by bearing seats, and the axial position of the drive shaft 171 can be restricted by the bearing seats. That is to say, the axis of the drive shaft 171 is set along the second direction and will not move along the second direction.

[0269] The first drive wheel 141 is rotatably supported on the first support plate 120 via a bearing, and the drive shaft 171 is slidable within the inner bore of the bearing, so that the drive shaft 171 does not affect the movement of the first support plate 120 in the second direction. Similarly, the second drive wheel 151 is rotatably supported on the second support plate 130 via a bearing, and the drive shaft 171 is slidable within the inner bore of the bearing, so that the drive shaft 171 does not affect the movement of the second support plate 130 in the second direction.

[0270] The hopper device 100 disclosed herein also includes a lifting assembly 180, which is used to raise a pallet between a first support plate 120 and a second support plate 130 to a preset position, wherein the pallet is in a loading station at the preset position.

[0271] The lifting assembly 180 disclosed herein may include a lifting drive device 181 and a pallet support 182 driven by the lifting drive device 181 to generate lifting; specifically, the lifting drive device 181 disclosed herein may be fixed on a vertical plate 183, at which time the vertical plate 183 is set approximately vertically, and its lower end can be fixed to the bottom plate 110 of the silo.

[0272] The lifting drive device 181 can be a ball screw structure; alternatively, it can be a linear motion mechanism such as a cylinder or hydraulic cylinder. Two guide rails are provided on the upright plate 183, both vertically positioned, allowing the lifting drive device 181 to be located in the area between the two guide rails.

[0273] The pallet support 182 is slidably disposed on the upright plate 183. For example, the pallet support 182 is provided with a slider, which is slidably disposed on the guide rail provided on the upright plate 183, so that the pallet support 182 can move relative to the upright plate 183, that is, the pallet support 182 is driven and can generate vertical movement.

[0274] In one embodiment, the pallet support 182 is also fixed to the nut of the ball screw mechanism, so that the lifting drive device 181 can drive the pallet support 182 to produce lifting motion.

[0275] Therefore, when the replenishment system of this disclosure is in use, after all the material in the pallet on the buffer device 400 or the redundant bearing device 790 is removed, the conveying device 700 will move the empty pallet to the pallet support 182. The empty pallets will be stacked on the pallet support 182. Correspondingly, as more and more empty pallets are stacked, the pallet support 182 will gradually descend. When the number of stacked pallets reaches a preset threshold, the pallet support 182 will be lowered below the first hopper conveying assembly 140 and the second hopper conveying assembly 150. At this time, the stacked empty pallets will be output outward by the first hopper conveying assembly 140 and the second hopper conveying assembly 150.

[0276] Figure 29 and Figure 30 This is a structural schematic diagram of the first door panel base and the first door panel opening / closing part of a hopper device according to one embodiment of the present disclosure.

The first door panel switch part 125 is driven by the first door panel switch part driving device 127 and is in the state of opening the hopper device 100 or closing the hopper device 100.

[0278] Specifically, when the first door panel switch 125 is in the open state of the hopper device 100, the first door panel base 124 and the first door panel switch 125 are in approximately the same vertical plane; when the first door panel switch 125 is in the closed state of the hopper device 100, the first door panel base 124 and the first door panel switch 125 are perpendicular to each other, and the first door panel switch 125 is used to block the pallet inside the hopper device 100.

[0279] In this disclosure, the first door panel base 124 can be driven by the first door panel base driving device 126 so that the first door panel base 124 can slide along the first guide rod 123, thereby the hopper of this disclosure can adapt to pallets of different lengths.

[0280] In one specific embodiment, the first door panel base driving device 126 can be a ball screw structure; of course, it can also adopt other linear motion mechanisms. The ball screw mechanism can be implemented using existing technologies, which will not be elaborated upon here.

[0281] Furthermore, the first door panel switch 125 of this disclosure can be driven by the first door panel switch drive device 127, so that the first door panel switch 125 can rotate relative to the first door panel base 124 by a preset angle. Specifically, the first door panel base 124 can rotate 90° relative to the first door panel switch 125, thereby enabling the first door panel switch 125 to be in an open hopper device state or a closed hopper device state.

[0282] In one specific embodiment, the first door panel switch driving device 127 can be a cylinder, one end of which is hinged to the first door panel base 124, and the second end of which is hinged to the first seat component 128. The first seat component 128 is fixed to the first door panel switch 125, so that the rotation of the first door panel switch relative to the first door panel base 124 can be driven by the extension and retraction of the cylinder.

The second door panel switch part 135 is driven by the second door panel switch part driving device 137 and is in the state of opening the hopper device 100 or closing the hopper device 100.

[0285] Specifically, when the second door panel switch 135 is in the open state of the hopper device 100, the second door panel base 134 and the second door panel switch 135 are in approximately the same vertical plane; when the second door panel switch 135 is in the closed state of the hopper device 100, the second door panel base 134 and the second door panel switch 135 are perpendicular to each other, and the second door panel switch 135 is used to block the pallet inside the hopper device 100.

[0286] In this disclosure, the second door panel base 134 can be driven by the second door panel base driving device 136 so that the second door panel base 134 can slide along the second guide rod 133, thereby the hopper of this disclosure can adapt to pallets of different lengths.

[0287] In one specific embodiment, the second door panel base drive device 136 can be a ball screw structure; of course, it can also adopt other linear motion mechanisms. The ball screw mechanism can be implemented using existing technologies, which will not be elaborated upon here.

[0288] Furthermore, the second door panel switch 135 disclosed herein can be driven by the second door panel switch drive device 137, so that the second door panel switch 135 can rotate relative to the second door panel base 134 by a preset angle. Specifically, the second door panel base 134 can rotate 90° relative to the second door panel switch 135, thereby enabling the second door panel switch 135 to be in an open hopper device state or a closed hopper device state.

[0289] In one specific embodiment, the second door panel switch driving device 137 can be a cylinder, one end of which is hinged to the second door panel base 134, and the second end of which is hinged to the second seat component 138. The second seat component 138 is fixed to the second door panel switch 135, so that the rotation of the second door panel switch relative to the second door panel base 134 can be driven by the extension and retraction of the cylinder.

[0290] See again Figures 29 to 32 A second blocking part 139 is provided on the second rear upright plate. The second blocking part 139 is located above the end of the second hopper conveying assembly 150 near the lifting assembly 180, so that the pallet of the present disclosure can be accurately limited in the hopper.

[0291] In one embodiment of this disclosure, the hopper device 100 further includes a pallet detection device for detecting the presence signal of a pallet. That is, the pallet detection device can detect the presence or absence of a pallet. In a preferred embodiment, the pallet detection device can be a through-beam switch, a photoelectric sensor, or a diffuse reflection sensor, and multiple devices can be configured to detect pallets from multiple locations.

[0292] Based on the above structure, the space inside the hopper device of this disclosure can be changed according to the size of the pallet, so that the pallet can be accurately positioned and stably held in the hopper device. Its structure is stable, highly accurate, fast, and easy to assemble.

[0293] The material replenishment system disclosed herein can effectively detect the location of material shortages in the material tray and then automatically replenish the material, which greatly improves production efficiency compared to the manual replenishment in the prior art.
