Description

Technical Field

[0001] This application relates to the field of conveying technology, and in particular to conveying mechanisms and material handling devices. Background Technology

[0002] In industries with high cleanliness requirements, such as electronics manufacturing, food processing, and medical devices, the transfer of materials between workshops has long relied on manual handling. For example, when materials are transferred from a Class 100 elevated workshop to a Class 1000 workshop, because there is usually a step difference of more than 1.5 meters between the two workshops, operators still need to manually move the materials from the high-level transfer port to the low-level work station.

[0003] This process requires at least two workers to work together to move the materials, and the moving efficiency is low. Moreover, the high step difference makes it very easy for materials to fall during the handling process, which not only causes product scrap but may also cause work-related injuries due to materials hitting personnel.

[0004] Therefore, existing transportation methods suffer from poor transportation efficiency and reliability. Utility Model Content

[0005] Therefore, it is necessary to provide a conveying mechanism and material turnover device to address the problems of poor conveying efficiency and reliability of existing conveying methods.

[0007] A transfer box, the transfer box having a conveyor line inside; the conveyor line includes a mounting frame, a conveyor drive, and multiple conveyor rollers rotatably connected to the mounting frame; the conveyor drive is connected to the conveyor rollers to drive the multiple conveyor rollers to rotate;

[0008] An angle adjustment unit is provided, which is connected to the mounting frame. The angle adjustment unit is used to drive the mounting frame to move, so as to adjust the tilt angle of the conveyor line. The tilt angle of the conveyor line is the angle between the conveying surface of the conveyor line and the horizontal plane.

[0009] In one embodiment, the tilt adjustment unit includes an adjustment drive and an adjustment output connected to the adjustment drive, the adjustment output being connected to the mounting bracket;

[0014] The controller can control the damper to generate damping force based on the trigger signal of the arrival detection device and the speed data of the speed measuring device, so as to reduce the material conveying speed.

[0015] In one embodiment, the conveying mechanism further includes a hinge, through which the mounting bracket is rotatably connected to the transfer box.

[0016] In one embodiment, the transfer box is provided with at least two layers of conveyor lines distributed along the direction of gravity; at least one layer of conveyor lines is used to carry materials weighing less than 10 kg; and at least one layer of conveyor lines is used to carry materials weighing greater than or equal to 10 kg.

[0017] In one embodiment, the inlet side of the transfer box is further provided with a pressure detection element and a guide diversion unit, the guide diversion unit being communicatively connected to the pressure detection element; the guide diversion unit can guide the material into one layer of the conveyor line according to the material weight detected by the pressure detection element.

[0018] In one embodiment, the guiding and diverting unit includes a diverting drive and a guide plate connected to the diverting drive;

[0019] The diversion drive is communicatively connected to the pressure detection element. The diversion drive can drive the guide plate to rotate according to the material weight detected by the pressure detection element, so that the guide plate is connected to one of the conveyor lines.

[0020] A material handling device includes a conveying mechanism as described above and a receiving trolley disposed on the outlet side of the conveying mechanism.

[0021] In one embodiment, the receiving cart includes a lifting drive and a receiving tray connected to the lifting drive. The lifting drive is used to drive the receiving tray to rise or fall so that the material conveyed by the conveying mechanism can be transferred to the receiving tray.

[0022] The aforementioned conveying mechanism and material turnover device drive the conveyor rollers to rotate via the conveying drive component, which can actively drive the material movement without manual pushing, thus realizing the turnover and conveying of materials. At the same time, the tilt angle of the conveyor line can be adjusted by the tilt angle adjustment unit, so that the material can be driven and conveyed along the inclined surface of the conveyor rollers, realizing the automated transfer of materials from the high-bay workshop to the Class 1000 workshop, replacing manual handling, improving the transfer efficiency of materials from the Class 100 workshop to the Class 1000 workshop, and reducing the risk of product scrapping or material impact on workers caused by material falling during manual handling, thereby improving conveying efficiency and reliability.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] In industries with high cleanliness requirements, such as electronics manufacturing, food processing, and medical devices, material handling between workshops has long relied on manual labor. For example, when materials (such as semiconductor chips or optical products) are transferred from a Class 100 elevated workshop (Class 100 means no more than 3,520 dust particles with a diameter greater than or equal to 0.5 micrometers per cubic meter of air, and elevated means the workshop uses an elevated structural design) to a Class 1000 workshop (Class 1000 means no more than 35,200 dust particles with a diameter greater than or equal to 0.5 micrometers per cubic meter of air), due to the typically greater than 1.5-meter height difference between the two workshops, operators still need to manually move the materials from the higher transfer port to the lower work station. This method suffers from poor handling efficiency and reliability.

[0037] Based on this, an embodiment of this application provides a conveying mechanism that can solve the above-mentioned technical problems. The conveying mechanism provided by an embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0038] See Figures 1 to 4As shown, an embodiment of this application provides a conveying mechanism including a transfer box 100 and an angle adjustment unit 200. The transfer box 100 is provided with a conveying line. The conveying line includes a mounting frame 110, a conveying drive 120, and a plurality of conveying rollers 130 rotatably connected to the mounting frame 110. The conveying drive 120 is connected to the conveying rollers 130 to drive the plurality of conveying rollers 130 to rotate. The angle adjustment unit 200 is connected to the mounting frame 110. The angle adjustment unit 200 is used to drive the mounting frame 110 to move in order to adjust the inclination angle of the conveying line. The inclination angle of the conveying line is the angle between the conveying surface of the conveying line and the horizontal plane.

[0039] The conveyor drive 120 drives the conveyor rollers 130 to rotate, actively moving materials without manual pushing, thus achieving material turnover and conveying. Simultaneously, the tilt angle of the conveyor line can be adjusted by the tilt adjustment unit 200, allowing materials to be driven and conveyed along the inclined surface of the conveyor rollers 130. This achieves automated material transfer from the high-bay workshop to the Class 1000 workshop, replacing manual handling and improving the efficiency of material transfer from the Class 100 to the Class 1000 workshop. It also reduces the risk of product scrapping due to material falling or material impacting workers during manual handling, improving conveying efficiency and reliability. The synchronous rotation of multiple conveyor rollers 130 ensures even force distribution on the bottom of the material, avoiding tilting or jamming caused by single-point force.

[0040] See Figures 1 to 4 As shown, in one embodiment, the tilt adjustment unit 200 includes an adjustment drive 210 and an adjustment output 220 connected to the adjustment drive 210. The adjustment output 220 is connected to the mounting bracket 110. The adjustment drive 210 drives the adjustment output 220 to move, thereby adjusting the tilt angle of the mounting bracket 110. Changing the tilt angle of the mounting bracket 110 by moving the adjustment output 220 via the adjustment drive 210 makes angle adjustment more flexible. The movement of the adjustment drive 210 can be precisely controlled according to actual needs, thereby achieving tilt angle adjustment of the mounting bracket 110 to different degrees and directions.

[0041] In some embodiments, the bottom of the mounting frame 110 is provided with rotation fulcrums, such as rotating shafts or hinge shafts, on both sides along the conveying direction. The rotation fulcrums are fixed to the inner wall of the transfer box 100, allowing the mounting frame 110 to rotate around the fulcrums. The adjustment drive 210 can be installed on the side wall or bottom wall of the transfer box 100, and can be a linear motor or cylinder. The output drive can be a connecting rod connected to the adjustment drive 210. The adjustment output 220 pushes or pulls one side of the mounting frame 110 through the connecting rod, causing the mounting frame 110 to tilt around the fulcrum, thereby changing the tilt angle of the conveyor line.

[0042] In one embodiment, the tilt adjustment unit 200 further includes a controller and a distance detection element communicatively connected to the controller. The controller is communicatively connected to the adjustment drive element 210. The controller can control the adjustment drive element 210 to adjust the tilt angle of the conveyor line based on the step difference detected by the distance detection element. Understandably, the step difference is the height difference between the receiving plane (inlet) and the discharge plane (outlet). For example, when the conveyor mechanism is used to transfer materials from a Class 100 high-bay workshop to a Class 1000 workshop, the step difference is the height difference between the receiving ports of the two workshops. When used in conjunction with a receiving trolley to transfer materials, the discharge plane can be the height of the receiving tray of the receiving trolley. Understandably, the communication connection methods include wired communication and wireless communication. Wired communication connections include serial communication, Ethernet communication, etc., while wireless communication includes Bluetooth communication, WiFi communication, RFID communication, etc.

[0043] The step difference is detected in real time by a distance sensor, and the relevant data is fed back to the controller. Based on this accurate data, the controller controls the adjustment drive 210 to precisely adjust the tilt angle of the conveyor line. Compared to manual adjustment based on experience or rough estimation, this method achieves more precise angle settings and better meets the specific tilt angle requirements of different production stages and material conveying. The entire process requires no continuous manual intervention; the controller automatically directs the adjustment drive 210 based on the detection data, achieving automated angle adjustment. This significantly saves labor costs and adjustment time, allowing the conveyor line tilt angle adjustment to quickly respond to changes in production needs, improving overall work efficiency, and ensuring efficient, smooth, and continuous operation of the material conveying process.

[0044] By precisely adjusting the tilt angle, materials can be conveyed at the appropriate angle on the conveyor line, preventing abnormal situations such as slippage, accumulation, and collisions caused by improper angles, thus maintaining the stability of the material conveying process. Simultaneously, it reduces potential safety hazards caused by unstable material conveying, such as material spillage injuring surrounding equipment or personnel, thereby improving the safety of production operations. In some embodiments, the distance detection element can be a laser rangefinder sensor.

[0045] See Figures 1 to 4As shown, in one embodiment, a damper, a position detection element 140, and a speed measuring element 150 are provided at the end of the conveyor line. All three elements are communicatively connected to a controller. The controller can control the damper to generate damping force based on the trigger signal from the position detection element 140 and the speed data from the speed measuring element 150, thereby reducing the material conveying speed. When the material reaches the end of the conveyor line, if it is not properly decelerated, it may violently collide with the receiving cart at the end due to inertia, resulting in surface scratches, deformation, or even damage to the material. This design allows the damper to function appropriately, smoothly decelerating the material and effectively reducing the impact force between the material and the end structure, thus maximizing the protection of the material's integrity.

[0046] Based on the real-time speed data acquired by the speed measuring device 150, the controller clearly understands the current conveying speed of the material. Combined with the trigger signal from the positioning detection device 140, it can accurately determine whether the material is approaching the end of the conveyor line and its current speed. Based on this accurate information, the damper can be precisely controlled to generate the corresponding damping force, achieving fine-tuning of the material conveying speed. This ensures that the material is conveyed in an orderly and stable manner, avoiding problems such as material accumulation and jamming caused by sudden speed changes. This allows the entire conveying process to proceed smoothly and continuously, improving the continuity and efficiency of production operations and reducing production downtime caused by conveying failures.

[0047] In some embodiments, the arrival detection element 140 can be a photoelectric sensor. This type of sensor is highly sensitive and accurate, and its non-contact nature does not interfere with the material, making it easy to install and use. The damper can be a hydraulic damper, which utilizes the resistance generated when hydraulic oil flows within structures such as piston cylinders to achieve a damping effect. When the controller issues a command, it adjusts parameters such as the flow rate and pressure of the hydraulic oil to change the magnitude of the damping force, thereby slowing down the material at the end of the conveyor line.

[0048] In one embodiment, the conveying mechanism further includes hinges, and the mounting frame 110 is rotatably connected to the transfer box 100 via the hinges. To ensure that the mounting frame 110 can rotate smoothly relative to the transfer box 100, multiple hinges can be symmetrically distributed. For example, when the mounting frame 110 is rectangular, two hinges can be installed on each of the two long sides of the mounting frame 110 to ensure even force distribution during rotation and avoid jamming or skewness caused by uneven force distribution. The hinges rotatably connect the mounting frame 110 to the transfer box 100, allowing the mounting frame 110 to rotate flexibly relative to the transfer box 100, facilitating easy adjustment of the tilt angle or orientation of the mounting frame 110 according to actual needs. During the conveying process, some impact forces are unavoidable, such as the inertial force generated when materials start and stop on the conveyor line, and vibrations that may occur at the connection points of different components. The hinges have a certain amount of flexibility and buffering capacity, which can absorb and buffer these impact forces to a certain extent, reducing damage to the mounting frame 110 and the overall structure of the transfer box 100. Furthermore, when the mounting frame 110 or the transfer box 100 undergoes slight deformation due to long-term stress, temperature changes, or other factors, the hinge can still maintain the effectiveness of the relative connection between the two through its own rotational adaptability, thus maintaining the normal operation of the conveying mechanism.

[0049] In some embodiments, the hinge includes a hinge shaft and at least two hinge plates. The at least two hinge plates are respectively connected to the mounting frame 110 and the transfer box 100. The hinge shaft passes through a connecting hole in one of the hinge plates, allowing the hinge plates to rotate around the hinge shaft, thereby achieving a rotatable connection between the mounting frame 110 and the transfer box 100. In some embodiments, a bushing is also provided between the hinge shaft and the hinge plates. The bushing is typically made of a wear-resistant, self-lubricating material, such as copper alloy or oil-impregnated nylon. The bushing further reduces friction between the hinge shaft and the hinge plates, lowering the wear rate. It also provides some support and positioning for the hinge shaft, making rotation smoother and more stable.

[0050] In one embodiment, the transfer box 100 has at least two layers of conveyor lines distributed along the direction of gravity; at least one conveyor line is used to carry materials weighing less than 10 kg; and at least one conveyor line is used to carry materials weighing 10 kg or more. Separating materials weighing less than 10 kg and materials weighing 10 kg or more onto different conveyor lines allows for a more reasonable load distribution on the conveyor lines. For conveyor lines carrying lighter materials, excessive loads prevent accelerated wear or damage; for conveyor lines carrying heavier materials, their design and selection better adapt to the heavier loads, reducing the possibility of equipment failure due to overload, extending equipment lifespan, and lowering equipment wear and maintenance costs. Because materials of different weights are conveyed on suitable conveyor lines, the conveying state of the materials can be better maintained, avoiding problems such as poor material sliding, tilting, or even falling due to mismatch between material weight and conveyor line, ensuring the stability of the conveying process, and improving the safety and reliability of material turnover. Understandably, each layer of conveyor rollers 130 is controlled by an independent conveyor drive unit 120, which can automatically match the rotation speed according to the weight of the material, ensuring that materials of different weights are conveyed smoothly at similar linear speeds.

[0051] In one embodiment, the inlet side of the transfer box 100 is further provided with a pressure detection element and a guiding and diverting unit, which is communicatively connected to the pressure detection element. The guiding and diverting unit can guide the material into one layer of the conveyor line based on the weight detected by the pressure detection element. The pressure detection element can detect the material weight in real time, and the guiding and diverting unit automatically guides the material into the corresponding conveyor line based on the detection result, without manual intervention. This achieves automated classification and conveying of materials, reduces manual operation, improves the automation and intelligence level of production, and also reduces labor costs and errors caused by human factors. In some embodiments, the pressure detection element can be a pressure sensor.

[0052] In one embodiment, the guiding and diverting unit includes a diverting drive and a guide plate connected to the diverting drive; the diverting drive is communicatively connected to a pressure detection element, and the diverting drive can drive the guide plate to rotate according to the material weight detected by the pressure detection element, so that the guide plate is connected to one of the conveyor lines.

[0053] Taking a three-layer conveyor line as an example, the upper conveyor roller 130 can be a polyurethane conveyor roller 130 with a diameter of 50 mm to 60 mm, used to carry lightweight materials weighing ≤10 kg; the middle conveyor roller 130 can be a metal conveyor roller 130 with a diameter of 80 mm to 90 mm, with an anti-slip rubber coating, suitable for carrying materials weighing 10 kg to 30 kg; the lower conveyor roller 130 can be a heavy-duty conveyor roller 130 with a diameter of 100 mm to 110 mm, made of high-strength alloy material, capable of bearing materials weighing over 30 kg. This layered design can automatically adapt to the weight of the material, avoiding conveying jams caused by uneven load in traditional single-layer conveyor roller 130 lines. When material enters the transfer window, the pressure detection element determines the weight and triggers the guide plate. If the weight is ≤10kg, the guide plate tilts downwards at 0 to 15 degrees, allowing it to connect with the upper conveyor roller 130 and guide the material into it. If the weight is between 10kg and 30kg, the guide plate tilts downwards at 15 to 30 degrees, connecting with the middle conveyor roller 130, allowing the material to enter. If the weight is greater than 30kg, the guide plate tilts downwards at 30 to 45 degrees, connecting with the lower conveyor roller 130, allowing the material to slide into it. The guide plate is telescopic; when it connects with a conveyor roller 130 of a certain layer, it can extend adaptively to connect with the guide plate of the corresponding layer.

[0054] In some embodiments, bearing seats may be symmetrically arranged on both sides of the mounting frame 110 for mounting the conveyor roller 130. The conveyor roller 130 may be made of seamless steel pipe with a polyurethane anti-slip layer on its surface to increase friction and prevent material slippage. Deep groove ball bearings may be installed at both ends of the conveyor roller 130, with the outer ring of the deep groove ball bearing embedded in the bearing seat of the mounting frame 110, allowing the conveyor roller 130 to rotate freely.

[0055] In some embodiments, the conveying drive 120 can use a motor as a power source. The motor output shaft can be connected to the active conveying roller 130 via a coupling, and the driven conveying rollers 130 can be driven together via a synchronous belt or chain. For example, the active conveying roller 130 drives the adjacent driven conveying roller 130 via a chain, and then the driven conveying roller 130 drives the subsequent conveying roller 130 via a synchronous belt, so as to realize the synchronous rotation of multiple conveying rollers 130.

[0056] See Figures 1 to 4 As shown, in one embodiment, the conveyor line includes a transmission unit 160 connected between the conveyor drive 120 and the conveyor rollers 130, so as to transmit the power of the conveyor drive 120 to each conveyor roller 130 through the transmission unit 160, so that each conveyor roller 130 can rotate around its own axis, thereby increasing the conveying speed of the conveying mechanism.

[0057] In one specific embodiment, the transmission unit includes a plurality of first transmission wheels; each first transmission wheel is connected to a conveying roller 130 in a one-to-one correspondence, and one of the first transmission wheels is connected to the conveying drive 120 to transmit the power of the conveying drive 120 to the conveying roller 130. Specifically, the conveying drive 120 is used to drive one of the first transmission wheels to rotate. Through the cooperation between the plurality of first transmission wheels, the power of the conveying drive 120 is simultaneously transmitted to each of the conveying rollers 130, thereby realizing the conveying of materials.

[0058] The first drive wheel and the conveyor roller 130 are detachably connected, facilitating the cleaning and replacement of the conveyor roller 130. In one embodiment, the first drive wheel and the conveyor roller 130 can be connected and fixed by a coupling or by a flange.

[0059] In one embodiment, the transmission unit further includes an annular transmission belt that wraps around the outer circumference of each first transmission wheel and is drivingly connected to each first transmission wheel. Thus, when one of the first transmission wheels rotates under the drive of the conveying drive 120, the other first transmission wheels will rotate synchronously due to the action of the transmission belt, thereby causing the multiple conveying rollers 130 to rotate synchronously, thereby realizing the conveying of materials. Specifically, the transmission belt and the first transmission wheels can be a belt-driven friction fit or a chain-driven meshing fit.

[0060] In one embodiment, each conveying roller 130 includes at least two segments, which are arranged at an axial distance from each other. Preferably, the conveying roller 130 includes two segments, and the axial extensions of the two segments are on the same straight line. This arrangement places the two conveying roller segments on opposite sides of the material, meaning that the two segments contact both ends of the material, while the middle of the material is suspended at the interval between the two segments. This ensures that only the ends of the material contact the conveying rollers 130, thereby reducing the contact area between the material and the conveying rollers 130 and preventing contamination or scratches from the conveying rollers 130.

[0061] like Figure 4As shown, in one embodiment, the transmission unit 160 includes a plurality of first bevel gears 161, a transmission shaft 163, and a plurality of second bevel gears 162 sleeved on the transmission shaft 163; each first bevel gear 161 is connected to a conveying roller 130 in a one-to-one correspondence, and each second bevel gear 162 meshes with a first bevel gear 161 in a one-to-one correspondence; the transmission shaft 163 is connected to the conveying drive member 120. Thus, the conveying drive member 120 drives each second bevel gear 162 to rotate through the transmission shaft 163, thereby causing the first bevel gears 161 meshing with the second bevel gears 162 to rotate, and thus causing the conveying rollers 130 connected to the first bevel gears 161 to rotate synchronously, thereby realizing the conveying of materials.

[0062] like Figure 5 As shown, in another embodiment, the transmission unit includes a plurality of first transmission gears 164 and a plurality of second transmission gears 165. The first transmission gears 164 and second transmission gears 165 are alternately arranged along the conveying direction and mesh with each other for transmission. One first transmission gear 164 or second transmission gear 165 is connected to the conveying drive member 120. Thus, when one of the first transmission gears 164 or second transmission gears 165 rotates under the drive of the conveying drive member 120, since two adjacent first transmission gears 164 and second transmission gears 165 mesh, the first transmission gears 164 and second transmission gears 165 at other positions will rotate synchronously, thereby causing the conveying roller 130 connected to the first transmission gear 164 to rotate synchronously, thereby realizing the conveying of materials.

[0063] like Figure 4 As shown, in one embodiment, the conveying roller 130 is provided with a limiting member 131 for contacting the material. The limiting member 131 is used to restrict the material from moving axially along the conveying roller 130. Since the material may deviate axially along the conveying roller 130 during the conveying process, the limiting member 131 can be provided at the end of the conveying roller 130 or other positions to prevent the material from deviating during the conveying process. Specifically, the limiting member 131 can be a limiting baffle provided at one axial end of the conveying roller 130, which limits the material contact.

[0064] Furthermore, such as Figure 1 As shown, one embodiment of this application also provides a material turnover device, including the conveying mechanism as described above and a receiving cart 300 disposed on the outlet side of the conveying mechanism. The material turnover device can be installed between two workshops, for example, between an elevated workshop and a Class 1000 cleanroom. The receiving cart 300 receives materials at the outlet side of the conveying mechanism, allowing materials to be quickly transferred from the conveying mechanism to the Class 1000 cleanroom, greatly reducing the labor intensity of manual handling and minimizing potential errors and safety hazards caused by manual handling.

[0065] In one embodiment, the receiving cart includes a lifting drive and a receiving tray connected to the lifting drive. The lifting drive is used to raise or lower the receiving tray so that the material conveyed by the conveying mechanism can be transferred to the receiving tray. By raising or lowering the receiving tray through the lifting drive, the height of the receiving tray can be flexibly adjusted to match the outlet of the conveying mechanism at different heights. This ensures that the material can be smoothly transferred from the conveying mechanism to the receiving tray, avoiding situations where the material falls and is damaged or cannot be transferred normally due to height differences. This enhances the adaptability of the entire material turnover device to different working conditions.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
