[0003] In automated manufacturing processes, material transfer between workstations in different directions is required. Currently, most material transfer tasks are accomplished using automated machinery such as robots. However, these robots and automated machinery have the following problems: complex structure: The complex design and structure of robots and other automated machinery increase the difficulty of manufacturing and maintenance.

[0004] Difficult to repair: Once damaged, it requires professional technicians to repair, which is costly and time-consuming.

[0005] High costs: As production lines increase, the number of automated machines such as robots also increases, leading to a significant rise in manufacturing costs. Summary of the Invention

[0011] As a preferred embodiment of the present invention, a fixed shaft is fixedly sleeved inside the rear side plate, and a second driven wheel is movably sleeved on the outer surface of the fixed shaft.

[0012] In a preferred embodiment of the present invention, the second driven wheel is connected to the second driving wheel via a second transmission belt, and a spacer is fixedly installed on the outer surface of the second transmission belt.

[0013] As a preferred embodiment of the present invention, a second pneumatic cylinder located on the right side of the coupling is fixedly installed at the top of the mounting plate, and a stop block located on the left side of the material conveyor belt is fixedly installed at the rear end of the second pneumatic cylinder.

[0014] As a preferred embodiment of the present invention, the material selected for the moving belt is one that minimizes the sum of friction loss and bending loss:

[0015] Collect the basic parameters of transmission belts made of different materials, and calculate the friction loss for each type of transmission belt:

[0016] Friction loss occurs at the contact surface between the transmission belt and the pulley, and can be expressed by the following formula:

[0017] P f =μF t v;

[0018] in:

[0019] P f It is the power loss due to friction;

[0020] μ is the coefficient of friction;

[0021] F t It is the tension of the drive belt;

[0022] v is the linear speed of the transmission belt;

[0023] Bending loss calculation:

[0024] Bending loss occurs due to the elastic deformation of the drive belt as it wraps around the pulley, and can be expressed by the following formula:

[0025]

[0026] in:

[0027] P b It is the power loss due to bending;

[0028] k b It is the bending loss coefficient;

[0029] R is the radius of the wheel;

[0030] F t It is the tension of the drive belt;

[0031] The material that minimizes the sum of friction loss and bending loss is selected as the material for the moving belt through calculation.

[0032] As a preferred embodiment of the present invention, the dynamic balance of the second transmission belt during high-speed operation is optimized by configuring the number of spacers and the mass and position of each spacer: the condition for dynamic balance is that the resultant force of the centrifugal forces generated by all spacers is zero, and the mathematical model is as follows:

[0033]

[0034] in:

[0035] m i It is the mass of the i-th partition;

[0036] r is the distance from the spacer to the center of the drive belt;

[0037] ω is the angular velocity of the transmission belt;

[0038] θ i It is the angle of the i-th partition relative to the reference point;

[0039] j is the imaginary unit;

[0040] Then, several schemes of "number of partitions and mass and position of each partition" are statistically analyzed, and the scheme that makes the resultant force of centrifugal force generated by all partitions zero is calculated and selected. Based on this, the vibration of the transmission belt is tested at different speeds, and the vibration amplitude and frequency are recorded. Then, a scheme of "number of partitions and mass and position of each partition" that meets the requirements of vibration amplitude and frequency is determined.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0076] like Figures 1 to 11 As shown, the present invention provides a rapid rotating material transfer structure, including a mounting plate 1. A material conveyor belt 2 is fixedly installed on the right side of the rear side of the top of the mounting plate 1. A drive motor 3 is fixedly installed at the bottom of the mounting plate 1. A drive shaft 4 is fixedly sleeved at the other end of the output shaft of the drive motor 3. The top end of the drive shaft 4 passes through the mounting plate 1 and extends to the top of the mounting plate 1 and is fixedly installed with a coupling 5. The bottom end of the coupling 5 is fixedly connected to the top end of the mounting plate 1. An upper rotating shaft 6 is fixedly installed at the top of the coupling 5. A special-shaped plate 7 is fixedly sleeved on the outer surface of the upper rotating shaft 6. The special-shaped plate 7 includes several mounting plates arranged around it. A first pneumatic cylinder 8 is fixedly installed on the side of the upper end of each mounting plate away from the upper rotating shaft 6. The bottom end of the first pneumatic cylinder 8 passes through the special-shaped plate 7 and extends to the bottom of the outer surface of the special-shaped plate 7 and is fixedly installed with a pad 9. A long plate 10 is fixedly installed at the bottom end of the pad 9. An electric suction cup 11 is fixedly sleeved inside the long plate 10.

[0077] When the first pneumatic cylinder 8 is activated, the pad 9, along with the long plate 10 and the electric suction cup 11, will move downwards until the bottom of the electric suction cup 11 contacts the outer surface of the material. At this point, the electric suction cup 11 will be activated to pick up and grip the material. Then, the first pneumatic cylinder 8 will be activated again, causing the material to return to its original position along with the long plate 10, thus lifting the material. Subsequently, the drive motor 3 will be activated, causing the drive shaft 4 to rotate through the coupling 5, thereby rotating the upper rotating shaft 6. This will cause the irregular plate 7, along with the first pneumatic cylinder 8, the pad 9, the long plate 10, and the electric suction cup 11, to rotate together, achieving rapid rotation and transfer of the material. This cycle is repeated, enabling rapid transfer of materials between different workstations in automated equipment and the aligning of disordered materials, thus replacing complex robots and reducing costs.

[0078] Among them, a side rotating shaft 12 is fixedly installed on the bottom right side of the outer surface of the coupling 5, and a first driving wheel 13 is fixedly sleeved on the outer surface of the side rotating shaft 12.

[0079] When the drive shaft 4 rotates, it will drive the upper rotating shaft 6 and the side rotating shaft 12 to rotate together through the coupling 5, thereby realizing the coupling rotation of the upper rotating shaft 6 and the side rotating shaft 12.

[0080] A bracket 14 is fixedly installed on the left side of the top of the mounting plate 1, a front side plate 15 is fixedly installed on the rear side of the outer surface of the bracket 14, and a rear side plate 16 is fixedly installed on the front side of the outer surface of the bracket 14.

[0081] The presence of bracket 14, front side plate 15 and rear side plate 16 will provide support.

[0082] The front side plate 15 of the bracket is movably sleeved with a connecting shaft 17. The right side of the outer surface of the connecting shaft 17 is fixedly sleeved with a first driven wheel 18. The first driven wheel 18 is connected to the first driving wheel 13 through a first transmission belt 19. The left side of the outer surface of the connecting shaft 17 is fixedly sleeved with a second driving wheel 20.

[0083] Since the first driven wheel 18 is connected to the first driving wheel 13 via the first transmission belt 19, when the first driving wheel 13 rotates, it will drive the first driven wheel 18 to rotate via the first transmission belt 19, thereby causing the first driven wheel 18 to drive the connecting shaft 17 and the second driving wheel 20 to rotate.

[0084] The rear side plate 16 is internally fixedly sleeved with a fixed shaft 21, and the outer surface of the fixed shaft 21 is movably sleeved with a second driven wheel 22.

[0085] The outer surface of the fixed shaft 21 and the inner surface of the second driven wheel 22 are both smooth, ensuring that the second driven wheel 22 will not get stuck when it rotates along the outer surface of the fixed shaft 21.

[0086] The second driven wheel 22 is connected to the second driving wheel 20 via the second transmission belt 23, and a spacer 24 is fixedly installed on the outer surface of the second transmission belt 23.

[0087] Since the second driven wheel 22 is connected to the second driving wheel 20 via the second drive belt 23, when the second driving wheel 20 rotates, the second drive belt 23 will rotate along with the spacer 24 under the combined action of the second driving wheel 20 and the second driven wheel 22.

[0088] The top of the mounting plate 1 is fixedly mounted with a second pneumatic cylinder 25 located on the right side of the coupling 5, and the rear end of the second pneumatic cylinder 25 is fixedly mounted with a stop block 26 located on the left side of the material conveyor belt 2.

[0089] When the second pneumatic cylinder 25 is activated, the stop block 26 will move, thereby blocking and intercepting the material conveyed by the material conveyor belt 2.

[0090] Working principle and usage process of this invention:

[0091] First, when the material is conveyed via the material conveyor belt 2, a vision detector located above the material conveyor belt 2 will detect the material. If the material is unqualified, the second pneumatic cylinder 25 will not be activated, and the unqualified material will be released. If the material is qualified, the second pneumatic cylinder 25 will be activated, causing the stop block 26 to move and block the material. Then, the first pneumatic cylinder 8 will be activated, causing the pad 9 to move down along the long plate 10 and the electric suction cup 11, which will then adsorb and grab the material. After the material is grabbed, the first pneumatic cylinder 8 will be activated again, lifting the material through the pad 9, long plate 10, and electric suction cup 11. Then, the drive motor 3 will be activated, causing the drive shaft 4 to rotate through the coupling 5, which in turn causes the upper rotating shaft 6 to rotate the irregular plate 7. When the material rotates to the top of the second transmission belt 23, the drive motor 3 will stop, and the first pneumatic cylinder 8 will be activated again, allowing the material to be lifted by the first pneumatic cylinder 8, the pad 9, the long plate 10, and the electric suction cup 11. The materials are placed between the partitions 24 on the second transmission belt 23 under the action of the suction cup 11. While the upper rotating shaft 6 rotates due to the drive motor 3 through the drive shaft 4 and the coupling 5, the side rotating shaft 12 will rotate the first driving wheel 13 under the action of the coupling 5. Since the first driving wheel 13 is connected to the first driven wheel 18 through the first transmission belt 19, the first driven wheel 18 will rotate the connecting shaft 17 and the second driving wheel 20 under the drive of the first transmission belt 19. Since the second driving wheel 20 is connected to the second driven wheel 22 through the second transmission belt 23, the second transmission belt 23 will rotate the partitions 24 under the combined action of the second driving wheel 20 and the second driven wheel 22, thereby ensuring that the materials are placed in an orderly manner. With the cooperation of various mechanisms, the problem of rapid transfer of materials between different workstations in automated equipment and the orderly arrangement of disordered materials is solved, thereby replacing the complex structure of the robot and reducing production costs.

[0092] Further implementation involves analyzing the energy loss of the transmission belt during power transmission through mathematical modeling, optimizing the transmission belt material, and reducing energy loss.

[0093] Collect basic parameters of transmission belts made of different materials:

[0094] Belt length L;

[0095] Drive belt width W;

[0096] Drive belt thickness t;

[0097] Drive belt density rho;

[0098] The linear speed v of the transmission belt;

[0099] Drive belt tension F t ;

[0100] The contact angle θ between the transmission belt and the wheel;

[0101] The coefficient of friction μ between the transmission belt and the wheel;

[0102] Sources of energy loss in transmission belts

[0103] Friction loss: Energy loss caused by friction between the transmission belt and the pulley.

[0104] Bending loss: Energy loss caused by the bending deformation of the drive belt as it passes over the wheel.

[0105] Friction loss calculation:

[0106] Friction loss occurs at the contact surface between the transmission belt and the pulley, and can be expressed by the following formula:

[0107] P f =μF t v;

[0108] in:

[0109] P f It is the power loss due to friction (W);

[0110] μ is the coefficient of friction;

[0111] F t It is the tension of the transmission belt (N);

[0112] v is the linear speed of the transmission belt (m / s);

[0113] Bending loss calculation:

[0114] Bending loss mainly occurs due to the elastic deformation of the drive belt as it passes over the pulley, and can be expressed by the following formula:

[0115]

[0116] in:

[0117] P b It is the bending power loss (W);

[0118] k b It is the bending loss coefficient;

[0119] R is the radius of the wheel (m);

[0120] F t It is the tension of the transmission belt (N);

[0121] The material selected for the moving belt should minimize the sum of friction loss and bending loss. For example, polyurethane (PU) can be chosen, which has a low coefficient of friction (0.3-0.5) and good wear resistance and tear resistance.

[0122] In further implementation, to optimize the dynamic balance of the second transmission belt during high-speed operation and reduce vibration and noise, the following specific details can be achieved: Establish a mathematical model where the second transmission belt has n partitions, each with a mass of m. i The position coordinates are x i (Along the length of the drive belt). We need to ensure the dynamic balance of these spacers during high-speed operation.

[0123] The condition for dynamic equilibrium is that the resultant force of the centrifugal forces generated by all the partitions is zero.

[0124]

[0125] in:

[0126] m i It is the mass of the i-th partition;

[0127] r is the distance from the spacer to the center of the drive belt;

[0128] ω is the angular velocity of the transmission belt;

[0129] θ i It is the angle of the i-th partition relative to the reference point;

[0130] j is the imaginary unit;

[0131] Configure the number of spacers and the mass and position of each spacer. Calculate to ensure that the resultant force of the centrifugal force generated by all spacers is zero. Based on this, test the vibration of the transmission belt at different speeds, record the vibration amplitude and frequency, and determine the number of spacers that meet the vibration amplitude and frequency requirements, as well as the mass and position of each spacer.

Based on this, the vibration of the transmission belt is tested at different speeds, and the vibration amplitude and frequency are recorded. Then, a scheme for the number of spacers and the mass and position of each spacer that meets the requirements of vibration amplitude and frequency is determined.
