Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, in particular to a rotary disc type feeding mechanism. Background Art

[0002] In automated motor assembly lines, the feeding system plays a crucial role, ensuring the continuous and timely supply of motor components to assembly stations, preventing production line halts due to component shortages. The feeding system precisely positions motor components, ensuring their correct installation during the assembly process, thereby safeguarding the quality and performance of the final product.

[0003] During actual operation, the number of components that need to be fed is large, and the delivery time is long. Collisions between components, failures in the delivery system, and fluctuations in delivery speed often occur, making it impossible for parts to be accurately delivered to the designated location, causing congestion or stagnation in the production line, affecting the continuity and efficiency of assembly. Especially for irregularly shaped components, collisions and misalignments often occur during the feeding process, causing damage to the motor components, or failure to correctly place them in the predetermined position, or fluctuations in the delivery speed of the motor component feeding system, which cannot match the speed of the robotic arm and the assembly line, resulting in production blockages or shutdowns. In addition, due to the lack of a reasonable and effective storage method for motor components, it is impossible to ensure sufficient and timely supply of parts, resulting in frequent production line stagnation.

[0004] Therefore, it is of great significance to design a rotary disc feeding mechanism that can solve the above problems. Utility Model Content

[0005] In order to solve the problems existing in the background technology, the utility model provides a rotary disc feeding mechanism, which includes a movable feeding bracket and a rotating mechanism and a lifting mechanism installed on the movable feeding bracket, wherein:

[0006] The rotating mechanism includes a turntable and a motor installed below the turntable for driving the turntable to rotate;

[0007] The turntable is provided with a plurality of through holes at intervals, and a material storage rack is installed at each through hole position; the material storage rack includes a base and at least three first limiting rods installed on the base, and the materials are stacked inside the first limiting rods; the through hole is located at the center of the base;

[0008] The lifting mechanism includes a stand, a lifting seat screw and a lifting motor. A guide rail is provided on the stand in the vertical direction, and the lifting seat is slidably connected to the stand via the guide rail. A nut slider is provided inside the lifting seat, and the lifting motor is installed on the stand. The lifting motor is connected to the nut slider via a screw to drive the lifting seat to move up and down.

[0009] An ejection mechanism is installed on the lifting seat. The ejection mechanism includes a push rod, the lower end of the push rod is connected to the lifting seat, and the upper end is equipped with a top cap that can pass through the through hole of the turntable.

[0010] In a preferred solution, the storage rack is provided with three first limiting rods, and the three limiting rods are evenly arranged at intervals of 120°.

[0011] In a preferred solution, a second limiting rod is further provided inside the first limiting rod.

[0012] In a preferred solution, 18 through holes are evenly opened on the turntable at intervals of 20 degrees, and 18 storage racks are installed correspondingly.

[0013] In the preferred solution, a conveying mechanism is also installed on the mobile loading bracket, and the conveying mechanism includes a base connected to the mobile loading bracket, and the Y-axis conveying mechanism and the Z-axis conveying mechanism are installed on the base, and the Z-axis moving mechanism is connected to the Y-axis moving mechanism by sliding along the Y-axis direction, and the Z-axis moving mechanism is equipped with a connecting seat connected to the Z-axis moving mechanism by sliding along the Z-axis direction, and a manipulator is installed at the bottom of the connecting seat.

[0014] In a preferred solution, an assembly table is provided in front of the movable loading bracket and below the Z-axis moving mechanism.

[0015] In a preferred solution, sensors are installed at the top and bottom positions of the first limiting rod.

[0016] The beneficial effects achieved by the utility model are:

[0017] First, the invention has designed a turntable with an ejection mechanism installed under the turntable. The ejection mechanism is driven by the lifting mechanism to eject the materials quickly, so that the materials in the storage rack can always be kept at a high position, which is convenient for the robot to grab. When all the materials in a storage rack are taken out, the rotation of the turntable will rotate the next storage rack to the material taking station. Repeating the above actions can realize fast and orderly feeding, which significantly improves the feeding efficiency and reduces the waiting and searching time in the traditional feeding method.

[0018] Secondly, the design of the storage rack ensures the stability of materials during storage and ejection, effectively improving the accuracy of feeding and reducing the rate of material damage. The mechanism is also highly adaptable and can be adjusted according to the size and shape of different materials to meet various feeding needs.

[0019] Third, in conjunction with the conveying mechanism and the manipulator, the rotary disc feeding mechanism realizes the automatic grabbing, handling and assembly of materials, improves the automation level of the production line, and reduces manual intervention, thereby reducing labor costs and improving the economic benefits of the enterprise.

[0020] Fourth, through its rational layout and operational flow design, the present invention is able to closely coordinate with other production equipment, optimizing the entire production process and improving the overall efficiency and stability of the production line. The precise feeding and assembly process also reduces errors and defects caused by human factors, further improving product quality and consistency. It can continuously and stably supply materials, avoiding production line stagnation and interruptions due to material shortages, and enhancing the continuity and stability of the production line, making the present invention's rotary disc feeding mechanism play an important role in automated production lines.

[0034] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Reference Figures 1-11 The present invention provides a rotary disc feeding mechanism, which includes a mobile feeding bracket 2 and a rotating mechanism 1 and a lifting mechanism 7 mounted on the mobile feeding bracket 2. The rotating mechanism 1 includes a turntable 12 and a motor mounted below the turntable 12 for driving the turntable 12 to rotate. The turntable 12 is provided with a plurality of through holes at intervals, and a storage rack 3 is mounted at each through hole. The storage rack 3 includes a base 31 and at least three first limiting rods 32 mounted on the base 31, and the materials 4 are stacked inside the first limiting rods 32. The through holes are located at the center of the base 31. The storage rack 3 is preferably provided with three first limiting rods 32, and the three limiting rods are evenly spaced at 120° intervals. A second limiting rod 33 is also provided inside the first limiting rod 32. The number of second limiting rods 33 can be designed according to the shape of the materials 4 to ensure the stability of the stacked materials 4.

[0036] The lifting mechanism 7 includes a stand 73, a screw 71 for the lifting seat 72, and a lifting motor 74. A guide rail is provided on the stand 73 in the vertical direction, and the lifting seat 72 is slidably connected to the stand 73 via the guide rail. A nut slider 721 is provided in the lifting seat 72, and the lifting motor 74 is installed on the stand 73. The lifting motor 74 is connected to the nut slider 721 via the screw 71, and is used to drive the lifting seat 72 to move up and down.

[0037] The lifting seat 72 is provided with an ejection mechanism 6, which includes a push rod 61. The push rod 61 has a lower end connected to the lifting seat 72 and an upper end provided with a top cap 62 that can pass through the through hole of the turntable 12. The turntable 12 is preferably provided with 18 through holes evenly spaced at 20° intervals, corresponding to the 18 storage racks 3.

[0038] A conveying mechanism 8 is also mounted on the mobile loading bracket 2. The conveying mechanism 8 includes a base 81 connected to the mobile loading bracket 2. A Y-axis conveying mechanism 82 and a Z-axis conveying mechanism 83 are mounted on the base 81. The Z-axis moving mechanism is slidably connected to the Y-axis moving mechanism along the Y-axis direction. The Z-axis moving mechanism is mounted on a connecting base 84 that is slidably connected to the Z-axis moving mechanism along the Z-axis direction. A manipulator 85 is mounted at the bottom of the connecting base 84. An assembly table 9 is provided in front of the mobile loading bracket 2 and below the Z-axis moving mechanism.

[0039] Sensors 5 are mounted at the top and bottom of the first limit rod 32. These sensors can be either acoustic or laser sensors. These acoustic sensors detect the material level by measuring the reflection of sound waves between the material 4 and the sensor 5 and the duration of the radar echo. These sensors measure the time difference between the emission and reception of the sound wave to determine the distance between the material 4 and the sensor 5, and thus the presence of material 4 at that height. Laser sensors determine the height of the material 4 by measuring the reflection of the laser and the radar echo time. The laser sensor 5 emits a laser beam. When the laser beam reflects off the surface of the object being measured, the light returns and is received by a laser receiver. By recording the time difference between the emission and reception of the laser beam, the sensor 5 calculates the distance between the laser radar and the object being measured, thereby determining the presence of material 4 at that height. The use of these sensors and control systems allows for real-time monitoring of the location, quantity, and status of the material 4. Any faults or abnormalities can be promptly detected and addressed, reducing maintenance complexity and costs.

[0040] When the utility model is in operation, the following steps are performed:

[0041] Initial state:

[0042] The rotary disc feeding mechanism is in a standby state, the turntable 12 is stationary, the lifting mechanism 7 including the lifting seat 72 and the ejection mechanism 6 is at the lowest position, and the manipulator 85 is at the initial position.

[0043] The storage rack 3 has been installed at the various through-hole positions of the turntable 12, and the materials 4 are stacked on the inner sides of the first limit rod 32 and the second limit rod 33 of the storage rack 3. The materials 4 are stacked, and a space for the materials 4 is reserved from the highest position. The highest position is the position where the manipulator 85 can grasp and keep it stable.

[0044] Start feeding:

[0045] When the assembly table 9 needs to be fed, the control system starts the lifting motor 74 of the rotary disc feeding mechanism to start working. The lifting motor 74 drives the lifting seat 72 to rise vertically along the guide rail on the stand 73 by driving the screw 71 and cooperating with the nut slider 721.

[0046] The ejection mechanism 6 on the lifting seat 72 rises accordingly, and the top cap 62 at the upper end of the ejector rod 61 passes through the through hole of the turntable 12 and contacts the bottom of the material 4 in the storage rack 3.

[0047] Ejecting material 4:

[0048] The ejection mechanism 6 continues to rise, and pushes the material 4 in the storage rack 3 upward to a height of the material 4, making it easy for the manipulator 85 to grab it.

[0049] The material 4 remains stable during the ejection process, and due to the design of the storage rack 3 (such as the arrangement of the first limiting rod 32 and the second limiting rod 33), the material 4 will not tilt or fall.

[0050] Robot 85 grabs:

[0051] The robot arm 85 moves to the highest position through the cooperation of the Y-axis conveying mechanism 82 and the Z-axis conveying mechanism 83.

[0052] The robot 85 accurately grabs the high-position material 4 and moves to the assembly table 9 to release the material 4 , and the material 4 undergoes the next assembly action on the assembly table 9 .

[0053] Turntable 12 rotations:

[0054] When all the materials 4 in a storage rack 3 are taken away, the control system starts the rotating motor 11 below the turntable 12.

[0055] The rotating motor 11 drives the turntable 12 to rotate a certain angle (such as 20 degrees), and rotates the next storage rack 3 containing the material 4 to the top of the ejection mechanism 6.

[0056] Repeat the above process of ejection, grabbing and rotation to achieve continuous feeding.

[0057] Monitoring and Adjustment:

[0058] Sensors 5 are installed at the top and bottom of the storage rack 3 to monitor the position and quantity of the material 4 in real time.

[0059] When the amount of material 4 is insufficient or an abnormal situation occurs, the sensor 5 will send a signal to the control system, and the control system can adjust the feeding speed or perform fault processing in time.

[0060] End feeding:

[0061] When the production line no longer needs to feed materials, the control system stops all actions of the rotary disc feeding mechanism.

[0062] The lifting mechanism 7 returns to the lowest position, and the manipulator 85 returns to the initial position, waiting for the next start.

[0063] This rotary disc feeding mechanism realizes the rapid and orderly feeding of the material 4 through the coordinated cooperation of the rotation of the turntable 12, the ejection of the lifting mechanism 7 and the grabbing of the manipulator 85, thereby improving the automation level and feeding efficiency of the production line.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
