Description

Technical Field

[0001] This application relates to the technical field of material placement, and in particular to a material placement device and method. Background Technology

[0002] The main function of material sorting equipment is to arrange and arrange materials according to certain rules and requirements. It is widely used in many industries and can improve material sorting efficiency and save manpower.

[0003] In existing technologies, material handling equipment mainly uses clamping mechanisms (such as gripper cylinders) to grasp materials and transfer them, enabling them to be arranged in a regular pattern according to set requirements. However, when handling plate-shaped materials, the thinness of these materials results in a small clamping surface, leading to unsatisfactory gripping effects and the possibility of accidental detachment during material transfer, resulting in poor stability. Furthermore, for structurally fragile materials, the gripping method can easily damage the sidewalls. Therefore, there is an urgent need for a material handling equipment suitable for grasping plate-shaped materials to improve the stability of the material handling and reduce the possibility of accidental detachment during transfer. Summary of the Invention

[0004] To improve the stability of material placement, this application provides a material placement device and a placement method.

[0005] Firstly, the material placement device provided in this application adopts the following technical solution:

[0006] A material handling device includes a mounting frame, a transfer seat, a transfer mechanism, and a gripping mechanism. The bottom of the mounting frame is provided with a storage platform and a conveyor belt. The transfer seat is slidably mounted on the mounting frame, and the transfer mechanism is disposed on the mounting frame to drive the transfer seat to reciprocate between the storage platform and the conveyor belt. The gripping mechanism includes an adsorption head and a support component for supporting materials. The adsorption head is slidably mounted on the transfer seat to be able to lift and lower.

[0007] By adopting the above technical solution, when arranging materials, the transfer mechanism slides the transfer seat above the storage platform, then drives the adsorption head downwards, enabling it to apply negative pressure to the materials on the storage platform to grasp them. This allows the materials to be transferred and placed on the conveyor belt for output. After the adsorption head applies negative pressure to the materials, during the transfer process, the supporting components support the lower surface of the materials, improving the stability of the material gripping and reducing the possibility of accidental material detachment during transfer, thereby improving the stability of the material arrangement process.

[0008] Optionally, a lifting block is slidably installed on the side wall of the transfer seat, and the adsorption head is located at the bottom of the lifting block; the transfer seat is provided with a lifting cylinder, the cylinder body of the lifting cylinder is connected to the transfer seat, and the piston rod of the lifting cylinder is connected to the lifting block.

[0009] By adopting the above technical solution, the lifting and lowering of the adsorption head is achieved by controlling the extension and retraction of the piston rod of the lifting cylinder, so that the adsorption head can adsorb and grasp the material.

[0010] Optionally, the supporting assembly includes two swing arms symmetrically distributed on both sides of the lifting block, each swing arm being hinged to the side wall of the transfer seat; the lower end of each swing arm is connected to a supporting block, and the first spring is disposed between the two swing arms. Under normal conditions, the first spring forces the supporting blocks of the two swing arms to move away from each other; the side wall of each swing arm is rotatably connected to a guide wheel, and the side wall of the lifting block has a guide surface for the guide wheel to abut against. When the lifting block is raised, the lifting block forces the supporting blocks of the two swing arms to move closer to each other through the guide surface to support the lower surface of the material.

[0011] By adopting the above technical solution, after the adsorption head is moved above the storage platform, the lifting block is driven to move downward by the lifting cylinder. During the downward movement of the lifting block, the upper ends of the two swing arms move closer together under the action of the first spring, thereby causing the support blocks of the two swing arms to move away from each other to avoid the adsorption head, allowing the adsorption head to move downward and adsorb the upper surface of the material. After the adsorption head adsorbs the material, it drives the lifting block to rise. During the rising process, the guide surface forces the lower ends of the two swing arms to move closer together, so that the support blocks can support the lower surface of the material, improving the stability of the material gripping.

[0012] Optionally, the mounting frame is slidably mounted with a sliding block, and the transfer mechanism includes a fixed rack, a movable gear, a movable rack, and a driving component. The fixed rack is disposed on the side wall of the mounting frame, the movable gear is rotatably connected to the sliding block, and the movable rack is slidably mounted on the side wall of the mounting frame and connected to the transfer seat. The fixed rack and the movable gear, as well as the movable rack and the movable gear, are meshed and drive each other. The driving component is disposed on the mounting frame to drive the sliding block to reciprocate along the length direction of the fixed rack.

[0013] By adopting the above technical solution, the sliding block is driven to reciprocate through a driving component, causing meshing transmission between the fixed rack and the movable gear, and between the movable rack and the movable gear. This drives the transfer seat to reciprocate between the storage platform and the conveyor belt. Combined with the lifting and lowering of the suction head, materials on the storage platform are transferred one by one and placed on the conveyor belt, improving the overall operational convenience of the structure. The combination of the fixed rack, movable gear, and movable rack provides a "range extension" effect, enabling the transfer seat to reciprocate between the storage platform and the conveyor belt.

[0014] Optionally, a rotating shaft is rotatably mounted on the side wall of the mounting frame. The driving component includes a first connecting rod, a second connecting rod, and a drive motor. One end of the first connecting rod is connected to the rotating shaft, and one end of the second connecting rod is hinged to the end of the first connecting rod away from the rotating shaft, while the other end is hinged to a sliding block. The drive motor is mounted on the mounting frame to drive the rotating shaft to rotate.

[0015] By adopting the above technical solution, the rotating shaft is driven to rotate by the drive motor. Under the action of the first link and the second link, the sliding block can slide back and forth along the length direction of the fixed rack, thereby realizing that the transfer seat can slide back and forth between the storage platform and the conveyor belt.

[0016] Optionally, the mounting frame has a first section and a second section, the storage platform is located below the first section, and the conveyor belt is located below the second section; a translation seat is slidably mounted on the transfer seat, the sliding direction of the translation seat is the same as that of the transfer seat, and the suction head is disposed on the translation seat; a second spring is provided between the translation seat and the transfer seat, and when the transfer seat slides to the first section, the second spring forces the translation seat to face the storage platform; a limiting seat for the translation seat to abut is slidably mounted in the second section, and the mounting frame is provided with an adjusting component for adjusting the distance between the limiting seat and the translation seat.

[0017] By adopting the above technical solution, the distance between the limiting seat and the translation seat can be adjusted by adjusting the component, thereby controlling the maximum sliding amount of the translation seat when it slides from the first interval to the second interval. In other words, the position of the translation seat when it moves into the second interval each time can be controlled, thereby adjusting the specific position of the adsorption head in the second interval so that the position of the adsorption head when it moves into the second interval can be different each time. This allows multiple materials to be arranged sequentially along the width direction of the conveyor belt according to the design requirements.

[0018] Optionally, a rotating shaft is rotatably mounted on the side wall of the mounting frame, and a rotating rod is rotatably mounted on the side wall of the mounting frame, with circumferential linkage between the rotating rod and the rotating shaft; the adjusting assembly includes a rotating lead screw and a linkage component, the rotating lead screw is rotatably connected to the side wall of the mounting frame, both ends of the rotating lead screw extend along the sliding direction of the transfer seat, the rotating lead screw passes through the limiting seat and is threadedly connected to the limiting seat; the linkage component is disposed between the rotating rod and the rotating lead screw to drive the rotating rod and the rotating lead screw to rotate synchronously.

[0019] By adopting the above technical solution, the rotating rod and the rotating shaft are circumferentially linked, so that when the transfer seat slides, the rotating shaft can drive the rotating rod to rotate synchronously. Under the action of the linkage, the rotating screw is driven to rotate synchronously, thereby allowing the limiting seat to move closer to or further away from the translation seat, thus changing the maximum sliding amount of the translation seat when it slides from the first section to the second section. This allows the position of the adsorption head in the second section to be different each time, realizing the arrangement of multiple materials along the width direction of the conveyor belt according to design requirements, and improving the operational convenience of the overall structure.

[0020] Optionally, the side wall of the mounting frame is provided with a switching seat, in which a first gear and a second gear are rotatably mounted respectively. The first gear and the second gear mesh and drive each other. The first gear is sleeved on the outer peripheral wall of the rotating shaft, and the second gear is sleeved on the outer peripheral wall of the rotating rod.

[0021] By adopting the above technical solution, the meshing transmission of the first gear and the second gear realizes the circumferential linkage between the rotating shaft and the rotating rod, that is, when the rotating shaft rotates, it can drive the rotating rod to rotate synchronously.

[0022] Optionally, the switching seat is slidably mounted on the mounting frame so as to slide along the axial direction of the rotating shaft; multiple first gears are arranged along the axial direction of the rotating shaft, and the outer diameter of each first gear is set differently; multiple second gears are arranged along the axial direction of the rotating rod, and the outer diameter of each second gear is set differently; multiple first gears and multiple second gears are correspondingly arranged, and each first gear and its corresponding second gear are meshed and driven; the inner peripheral walls of the first gears and the second gears are provided with mating strips, and the end faces of the rotating shaft and the rotating rod are provided with mating joints, the mating joints having mating grooves for the mating strips to be embedded in.

[0023] By adopting the above technical solution, multiple first and second gears are correspondingly set. In actual operation, the position of the switching seat can be controlled to allow the first gear and the corresponding second gear to be embedded in the installation position (the installation position refers to: the mating strip of the first gear being embedded in the mating groove of the rotating shaft's connector, and the mating strip of the corresponding second gear being embedded in the mating groove of the rotating rod's connector), thereby achieving circumferential linkage between the rotating shaft and the rotating rod. By connecting different sets of first and second gears to the connector, the rotation ratio between the rotating shaft and the rotating rod can be changed, thereby controlling the rotation amount of the rotating screw, i.e., controlling the sliding amount of the limit seat. This allows the spacing between two adjacent materials in the width direction of the conveyor belt to be changed according to actual needs, improving the flexibility of the overall structure.

[0024] Secondly, the material placement method provided in this application adopts the following technical solution:

[0025] A material placement method includes the following steps: S1, feeding: stacking a certain amount of materials on a storage platform; S2, placement: placing the materials on a conveyor belt according to set requirements; S3, discharging.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the configuration of the adsorption head and supporting components, when materials are arranged, the transfer mechanism slides the transfer seat above the storage platform, then drives the adsorption head downwards, enabling it to apply negative pressure to the materials on the storage platform to grasp them. This allows the materials to be transferred and placed on the conveyor belt for output. After the adsorption head applies negative pressure to the materials, the supporting components support the lower surface of the materials during the transfer process, improving the stability of the material grasp and reducing the possibility of accidental material detachment during transfer, thereby improving the stability of the material arrangement process.

[0028] 2. By using a fixed rack and a movable rack, a driving component drives a sliding block to reciprocate, creating meshing transmission between the fixed rack and the movable gear, and between the movable rack and the movable gear. This causes the transfer seat to reciprocate between the storage platform and the conveyor belt. Combined with the lifting and lowering of the suction head, materials on the storage platform are transferred one by one and placed on the conveyor belt, improving the overall ease of operation. The combination of the fixed rack, movable gear, and movable rack provides a "range extension" effect, enabling the transfer seat to reciprocate between the storage platform and the conveyor belt.

[0029] 3. By adjusting the settings of the components, the distance between the limiting seat and the translation seat can be adjusted, thereby controlling the maximum sliding amount of the translation seat when it slides from the first interval to the second interval. This allows control over the position of the translation seat when it moves into the second interval each time, thereby adjusting the specific position of the adsorption head in the second interval. This ensures that the position of the adsorption head when it moves into the second interval is different each time, thus enabling multiple materials to be arranged sequentially along the width of the conveyor belt according to design requirements.

[0038] The following combination Figures 1-7 This application will be described in further detail.

[0039] Example 1: This application discloses a material placement device.

[0040] Reference Figure 1 , Figure 2 A material handling device includes a mounting frame 1, a transfer seat 2, a transfer mechanism 3, and a gripping mechanism 4. The mounting frame 1 is elongated, and a first section 13 and a second section 14 are formed sequentially along its length. A storage platform 5 and a conveyor belt 6 are respectively installed at the bottom of the mounting frame 1. The storage platform 5 is located below the first section 13 for stacking materials, and the conveyor belt 6 is located below the second section 14 for receiving materials.

[0041] The first slide rail 17 is fixedly installed on the side wall of the mounting frame 1. The two ends of the first slide rail 17 extend along the length of the mounting frame 1. The transfer seat 2 is slidably installed on the first slide rail 17 of the mounting frame 1. The transfer mechanism 3 is provided on the mounting frame 1 to drive the transfer seat 2 to reciprocate between the first section 13 and the second section 14 (i.e., between the storage platform 5 and the conveyor belt 6).

[0042] Reference Figure 1 , Figure 3The mounting frame 1 has a sliding groove 18 on its side wall, with both ends of the sliding groove 18 extending along the length of the mounting frame 1. A sliding block 11 is slidably installed in the sliding groove 18. The transfer mechanism 3 includes a fixed rack 31, a movable gear 32, a movable rack 33, and a driving component. The length directions of the fixed rack 31 and the movable rack 33 are both consistent with the length direction of the mounting frame 1. The fixed rack 31 is fixedly installed on the side wall of the mounting frame 1, and the movable gear 32 is rotatably connected to the sliding block 11. The movable rack 33 is slidably installed on the side wall of the mounting frame 1, and a connecting strip 331 is installed between the movable rack 33 and the transfer seat 2. The movable rack 33 and the transfer seat 2 are connected by the connecting strip 331. The fixed rack 31 and the movable gear 32, as well as the movable rack 33 and the movable gear 32, engage in transmission.

[0043] A driving component is mounted on the mounting frame 1 to drive the sliding block 11 to reciprocate along the length of the fixed rack 31. A rotating shaft 12 is rotatably mounted on the side wall of the mounting frame 1. The driving component includes a first connecting rod 34, a second connecting rod 35, and a driving motor 36. One end of the first connecting rod 34 is fixedly connected to the rotating shaft 12, and one end of the second connecting rod 35 is hinged to the end of the first connecting rod 34 away from the rotating shaft 12, and the other end is hinged to the sliding block 11. The driving motor 36 is fixedly mounted on the mounting frame 1. In this embodiment, the output shaft of the driving motor 36 is coaxially connected to the rotating shaft 12.

[0044] Reference Figure 1 , Figure 2 A gripping mechanism 4 is installed on the transfer seat 2 for gripping materials. The gripping mechanism 4 includes an adsorption head 41 and a support assembly for supporting the materials. A lifting block 21 is slidably installed on the side wall of the transfer seat 2. The adsorption head 41 is fixedly installed on the bottom of the lifting block 21. The adsorption head 41 is slidably installed on the transfer seat 2 via the lifting block 21 so that it can be raised and lowered. The adsorption head 41 is connected to an adsorption tube for extracting air (not shown in the figure). A lifting cylinder 22 is installed on the transfer seat 2. The cylinder body of the lifting cylinder 22 is fixedly connected to the transfer seat 2. The piston rod of the lifting cylinder 22 is connected to the lifting block 21. When the piston rod of the lifting cylinder 22 extends outward, the lifting block 21 moves downward.

[0045] Reference Figure 1 , Figure 2In this embodiment, the lifting block 21 includes a guide portion 212 and a connecting portion 213. The adsorption head 41 is installed at the bottom of the connecting portion 213, and the piston rod of the lifting cylinder 22 is connected to the guide portion 212. A lifting rod 214 is fixedly installed on the top wall of the connecting portion 213, and a lifting groove 215 through which a sliding rod passes is opened on the bottom wall of the guide portion 212. The connecting portion 213 is slidably installed on the guide portion 212 through the lifting rod 214. A third spring 216 is installed in the lifting groove 215. One end of the third spring 216 is fixedly connected to the lifting rod 214, and the other end is fixedly connected to the inner wall of the lifting groove 215.

[0046] The support assembly includes two swing arms 42 and a first spring 43. Two swing arms 42 are symmetrically distributed on both sides of the lifting block 21, and each swing arm 42 is hinged to the side wall of the transfer seat 2. A support block 421, made of rubber, is fixedly installed at the lower end of each swing arm 42. The two ends of the first spring 43 are fixedly installed at the upper ends of the two swing arms 42. Under normal conditions, the first spring 43 forces the upper ends of the two swing arms 42 closer together (i.e., forces the support blocks 421 of the two swing arms 42 to move away from each other).

[0047] Each swing arm 42 has a guide wheel 422 rotatably connected to its side wall. The guide portion 212 has guide surfaces 211 on both sides, with the two guide surfaces 211 corresponding to the guide wheels 422 of the two swing arms 42. The first spring 43 forces the outer peripheral walls of the guide wheels 422 of the two swing arms 42 to abut against the corresponding guide surfaces 211 of the guide portion 212. When the lifting block 21 is raised, the guide portion 212 forces the support blocks 421 of the two swing arms 42 to move closer together via the guide surfaces 211, thus supporting the lower surface of the material.

[0048] Reference Figure 1 , Figure 2 A first blocking block 217 is fixedly installed on the side wall of the connecting part 213, and a second blocking block 24 is fixedly installed on the side wall of the transfer seat 2. When the guide part 212 is raised and the guide surface 211 of the guide part 212 abuts against the guide wheel 422 of the swing rod 42, the second blocking block 24 abuts against the first blocking block 217 to block the connecting part 213. When the guide part 212 is driven to rise further, the support block 421 of the swing rod 42 supports the lower surface of the material.

[0049] The implementation principle of Embodiment 1 of this application is as follows: When arranging materials, the rotating shaft 12 is driven to rotate. Under the action of the first connecting rod 34, the second connecting rod 35, the fixed rack 31, the movable gear 32 and the movable rack 33, the transfer seat 2 can reciprocate between the first interval 13 and the second interval 14.

[0050] When the transfer seat 2 slides above the storage platform 5, it drives the adsorption head 41 to move downward, enabling the adsorption head 41 to apply negative pressure to the material on the storage platform 5 to grasp the material. After the adsorption head 41 grasps the material, it drives the lifting block 21 to rise. During the lifting process, the guide part 212 of the lifting block 21 forces the lower ends of the two swing rods 42 to move closer to each other through the guide surface 211, so that the support block 421 can support the lower surface of the material, improving the stability of the grasp of the material, reducing the possibility of the material accidentally falling off during the transfer process, and thus improving the stability of the material placement process.

[0051] Example 2: This application discloses a material placement device.

[0052] The difference between the material placement device disclosed in this application and Embodiment 1 is that:

[0053] Reference Figure 4 In this embodiment, the transfer seat 2 is elongated, and the length direction of the transfer seat 2 is consistent with the length direction of the mounting frame 1. A second slide rail 25 is fixedly installed on the side wall of the transfer seat 2. The two ends of the second slide rail 25 extend along the length direction of the transfer seat 2. A translation seat 23 is slidably installed on the second slide rail 25. In this embodiment, the adsorption head 41 is installed on the translation seat 23 (that is, the lifting cylinder 22, the lifting block 21, and the swing rod 42 and other related structures are all installed on the translation seat 23).

[0054] A second spring 231 is installed between the translation seat 23 and the transfer seat 2. One end of the second spring 231 is fixedly connected to the translation seat 23, and the other end is fixedly connected to the transfer seat 2. When the transfer seat 2 slides to the first interval 13, the second spring 231 forces the suction head 41 of the translation seat 23 to face the storage table 5. A limiting seat 15 for the translation seat 23 to abut is slidably installed in the second interval 14. The mounting frame 1 is provided with an adjusting component 7 for adjusting the distance between the limiting seat 15 and the translation seat 23.

[0055] Reference Figure 4 A rotating rod 16 is rotatably mounted on the side wall of the mounting frame 1. The rotating rod 16 is located below the rotating shaft 12 (the rotating shaft 12 is not shown in the figure of this embodiment). The rotating rod 16 and the rotating shaft 12 can be connected in series by a belt (not shown in the figure) so that the rotating rod 16 and the rotating shaft 12 are circumferentially linked (that is, when the rotating shaft 12 rotates, it can drive the rotating rod 16 to rotate synchronously).

[0056] The adjustment assembly 7 includes a rotating lead screw 71 and a linkage component. The side wall of the mounting frame 1 is provided with a mounting groove 19. Both ends of the mounting groove 19 extend along the length direction of the mounting frame 1. The rotating lead screw 71 is rotatably installed in the mounting groove 19 of the mounting frame 1. The length direction of the rotating lead screw 71 is consistent with the length direction of the mounting frame 1. The rotating lead screw 71 passes through the limiting seat 15 and is threadedly connected to the limiting seat 15 (the thread of the rotating lead screw 71 is not shown in the figure).

[0057] One end of the rotating rod 16 extends into the mounting groove 19. A linkage is disposed between the rotating rod 16 and the rotating lead screw 71 to drive the rotating rod 16 and the rotating lead screw 71 to rotate synchronously. The linkage includes a first bevel gear 72 and a second bevel gear 73. The first bevel gear 72 is coaxially fixed to one end of the rotating rod 16, and the second bevel gear 73 is coaxially fixed to one end of the rotating lead screw 71. The first bevel gear 72 and the second bevel gear 73 mesh with each other. It should be noted that in this embodiment, the drive motor 36 is a servo motor (i.e., the rotating shaft 12 can rotate in both forward and reverse directions).

[0058] The implementation principle of Embodiment 2 of this application is as follows: During the process of rotating the rotating shaft 12 and driving the transfer seat 2 to transfer between the storage platform 5 and the conveyor belt 6, the rotating screw 71 can rotate synchronously under the action of the rotating rod 16, so as to drive the limiting seat 15 to slide. Every time the rotating shaft 12 rotates once (that is, the transfer seat 2 completes one material placement), the limiting seat 15 can slide a certain distance along the length direction of the mounting frame 1, thereby controlling the sliding position of the translation seat 23 to the position of the second interval 14, so that the position of the translation seat 23 moving into the second interval 14 can be different each time, thereby enabling multiple materials to be placed sequentially along the width direction of the conveyor belt 6 as required.

[0059] When the limiting seat 15 gradually moves from above one side of the width direction of the conveyor belt 6 to above the other side of the width direction of the conveyor belt 6, the rotating shaft 12 is driven to rotate in the opposite direction, so that the sliding direction of the limiting seat 15 can be adjusted. In coordination with the conveyor belt 6, multiple materials can be evenly placed on the surface of the conveyor belt 6, which greatly improves the operational convenience of the overall structure.

[0060] Example 3: This application discloses a material placement device.

[0061] The difference between the material placement device disclosed in this application and Embodiment 2 is that:

[0062] Reference Figure 5 , Figure 6 , Figure 7In this embodiment, a switching seat 8 is installed on the side wall of the mounting frame 1. The switching seat 8 has a mounting cavity 85. A first gear 81 and a second gear 82 are rotatably installed in the mounting cavity 85. The first gear 81 and the second gear 82 mesh and drive each other. The first gear 81 is sleeved on the outer peripheral wall of the rotating shaft 12, and the second gear 82 is sleeved on the outer peripheral wall of the rotating rod 16. The rotating shaft 12 and the rotating rod 16 achieve circumferential linkage through the meshing of the first gear 81 and the second gear 82. The side wall of the switching seat 8 has a through hole 87 for the rotating shaft 12 and the rotating rod 16 to pass through.

[0063] Mounting rod 9 is mounted on the side wall of mounting frame 1. The axial direction of mounting rod 9 is consistent with the axial direction of rotating shaft 12. Mounting lug 86 is fixedly mounted on the side wall of switching seat 8. Mounting rod 9 passes through mounting lug 86. Locking nut 91 is threaded on the outer peripheral wall of mounting rod 9 (the thread of mounting rod 9 is not shown in the figure). There are two locking nuts 91 on the outer peripheral wall of mounting rod 9. The two locking nuts 91 are clamped together in the mounting lug 86 of switching seat 8. Switching seat 8 can be detachably mounted to mounting frame 1 through mounting rod 9 and locking nuts 91 so that its position can be adjusted along the length direction of mounting rod 9.

[0064] Reference Figure 7 In this embodiment, multiple first gears 81 are arranged along the axial direction of the rotating shaft 12, and the outer diameter of each first gear 81 is different. Multiple second gears 82 are arranged along the axial direction of the rotating rod 16, and the outer diameter of each second gear 82 is different. Multiple first gears 81 and multiple second gears 82 are arranged correspondingly, and each first gear 81 and its corresponding second gear 82 are meshed and driven.

[0065] Each first gear 81 and each second gear 82 has a mating cylinder 83 fixedly installed on its inner peripheral wall. A mating strip 831 is fixedly installed on the inner wall of the mating cylinder 83. A mating joint 84 is fixedly installed on the end face of the rotating shaft 12 and the rotating rod 16. The outer diameter of the rotating shaft 12 and the outer diameter of the rotating rod 16 are matched. The outer diameter of the mating joint 84 is larger than the outer diameter of the rotating shaft 12. The mating joint 84 and the rotating shaft 12, and the mating joint 84 and the rotating rod 16 can be connected by bolts (the bolt connection is not shown in the figure). The mating joint 84 has a mating groove 841 for the mating strip 831 to be inserted.

[0066] It should be noted that in this embodiment, the drive motor 36 is mounted on the side wall of the mounting frame 1. The output shaft of the drive motor 36 and the rotating shaft 12 can be connected in series by a belt (not shown in the figure) so that when the output shaft of the drive motor 36 rotates, it drives the rotating shaft 12 to rotate synchronously.

[0067] The implementation principle of Embodiment 3 of this application is as follows: Multiple first gears 81 and second gears 82 are set accordingly. In actual operation, the position of the switching seat 8 can be controlled so that the first gear 81 and the corresponding second gear 82 are embedded in the installation position (the installation position refers to: the mating strip 831 of the first gear 81 is embedded in the mating groove 841 of the mating joint 84 of the rotating shaft 12, and the mating strip 831 of the corresponding second gear 82 is embedded in the mating groove 841 of the mating joint 84 of the rotating rod 16), thereby realizing the circumferential linkage between the rotating shaft 12 and the rotating rod 16.

[0068] By switching between the first gear 81 and the second gear 82 with different transmission ratios between the rotating shaft 12 and the rotating rod 16, the rotation ratio between the rotating shaft 12 and the rotating rod 16 can be changed, thereby controlling the amount of sliding of the limit seat 15 for each rotation of the rotating shaft 12. This allows the spacing between two adjacent materials in the width direction of the conveyor belt 6 to be changed according to actual needs, improving the flexibility of the overall structure.

[0069] Example 4: This application also discloses a method for arranging materials.

[0070] A method for arranging materials specifically includes the following steps:

[0071] S1. Loading: Stack a certain amount of materials on storage platform 5.

[0072] S2, Display: According to the set requirements, the adsorption head 41 grabs the material on the storage platform 5 and places it on the conveyor belt 6 in sequence.

[0073] S3. Discharge: The neatly arranged materials are output via conveyor belt 6 to facilitate the next processing step.

[0074] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
