Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically an automatic feeding machine for oil-slinging caps. Background Technology

[0002] In existing technologies, the oil slinger caps on the rotor are basically installed manually or automatically by a feeding device. When installing manually, although the installation position of the oil slinger cap is precise and controllable, the manual efficiency is low, the labor demand is large, and the assembly cost is high. When installing with existing feeding devices, the positioning of the oil slinger cap requires manual intervention due to the use of a single robotic arm, which is not only inefficient but also prone to deviation, resulting in a decrease in product qualification rate. Therefore, an automatic feeding machine for oil slinger caps is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic feeding machine for oil-slinging caps in order to solve the above problems.

[0004] To achieve the above objectives, the following technical solution is provided: an automatic feeding machine for oil-slinging caps, comprising a frame and a stepper motor disposed at the bottom of the frame, characterized in that: it further comprises a rotating disk disposed on the frame and driven to rotate by the stepper motor, a plurality of uprights disposed on the rotating disk for stacking oil-slinging caps, a lifting device disposed at the bottom of one of the uprights for driving the oil-slinging caps on the uprights to be lifted step by step, a turnover frame disposed on the frame, a first robotic arm disposed at the top of the frame for grabbing the oil-slinging caps at the top of the uprights, a second robotic arm disposed at the top of the frame for grabbing the oil-slinging caps on the turnover frame and installing them onto the rotor and moving synchronously with the first robotic arm, and a controller for coordinating the action sequence of the rotating disk, the lifting device, the first robotic arm, and the second robotic arm; the turnover frame is further provided with a positioning groove for temporarily storing oil-slinging caps and a correction device rotatably connected to the positioning groove for correcting the position of the oil-slinging caps and also electrically connected to the controller.

[0005] Preferably, the upright is fitted with a support plate for supporting the oil-slinging cap.

[0006] Preferably, the lifting device is a step-by-step lifting structure, with each lifting height equal to the height of a single oil slinger cap. It includes a driver located at the bottom of the frame and a lever connected to the piston rod of the driver for actuating the lifting of the pallet.

[0007] Preferably, the correction device includes a position sensor mounted on a turnover rack for detecting the offset state of the oil slinger cap and a servo motor connected to the positioning slot and driving the oil slinger cap to rotate horizontally to a preset angle according to the position sensor signal.

[0008] Preferably, the turnover rack is located between the first robotic arm and the second robotic arm, serving as a buffer positioning area for the oil-slinging cap.

[0009] Preferably, the first and second robotic arms are provided with protective covers.

[0010] The beneficial effects of this utility model are as follows: By setting up a rotary table and driving the indexing rotation with a stepper motor, multiple upright workstations can be switched cyclically, avoiding downtime for material replacement during single-upright feeding and ensuring continuous drying. The lifting device allows for step-by-step elevation, ensuring the top oil-slinging cap is always in the gripping position. The overlapping action times of the first and second robotic arms reduce cycle time and improve production efficiency. The turnover rack acts as a temporary buffer, balancing the difference in working rhythm between the two robotic arms. Furthermore, the correction device uses position sensors to detect the oil-slinging cap's offset in real time and a servo motor for precise correction, ensuring a high success rate in assembling the oil-slinging cap to the rotor and improving product qualification rate. This achieves full-process automation, reducing manual intervention, lowering labor requirements and production costs, and improving enterprise economic benefits. Attached Figure Description

[0019] Participation Figure 1-4As shown, this embodiment of an automatic feeding machine for oil-slinging caps includes a frame 1 and a stepper motor 2 disposed at the bottom of the frame 1. It is characterized by further including: a rotating disk 3 disposed on the frame 1 and driven by the stepper motor 2 to rotate in increments; several uprights 4 disposed on the rotating disk 3 for stacking oil-slinging caps; a lifting device 5 disposed at the bottom of one of the uprights 4 for driving the oil-slinging caps on the uprights 4 to lift them step by step; a turnover frame 6 disposed on the frame 1; a first robotic arm 7 disposed at the top of the frame 1 for gripping the oil-slinging caps on the top of the uprights 4; a second robotic arm 8 disposed at the top of the frame 1 for gripping the oil-slinging caps on the turnover frame 6 and installing them onto the rotor, and moving synchronously with the first robotic arm 7; and a coordinating rotating disk 3. The lifting device 5, the first robotic arm 7, and the second robotic arm 8 are controlled by a controller 9. The turnover frame 6 is also equipped with a positioning groove 61 for temporarily storing oil-slinging caps and a correction device 62 rotatably connected to the positioning groove 61 for correcting the position of the oil-slinging caps and electrically connected to the controller 9. During operation, the controller 9 controls the stepper motor 2 to work according to a preset degree. The stepper motor 2 drives the rotating disk 3 to rotate in increments. The uprights 4 are evenly distributed along the circumference of the rotating disk 3. When the rotating disk 3 rotates, multiple uprights 4 are cyclically switched to the feeding position to achieve continuous feeding. The uprights 4 in the feeding position are driven by the driver 51 on the lifting device 5 to drive the lever 52. The lever 52 pushes the pallet 41 on the upright 4 to move. The pallet 41 is raised by one oil-slinger cap height each time, ensuring that the top oil-slinger cap is always in a position that is easy to grasp. The first robotic arm 7 grabs the oil-slinger cap from the top of the upright 4 and moves it to the positioning slot 61 on the turnover rack 6; the second robotic arm 8 simultaneously grabs the oil-slinger cap from the turnover rack 6 and installs it onto the rotor. The actions of the two robotic arms overlap, reducing the interval between cycles. After the oil-slinger cap is placed in the positioning slot 61, the position sensor 621 detects the cap's offset state. The servo motor 622, based on the signal from the position sensor 621, is instructed by the controller 9 to drive the positioning slot 61 to rotate horizontally with the oil-slinger cap to a preset angle, ensuring the installation accuracy of the oil-slinger cap installed on the rotor; through the setting of the rotating disk 3, the stepping... Motor 2 drives the indexing rotation, enabling cyclical switching between multiple upright positions 4, avoiding downtime for material changes when feeding a single upright 4, and ensuring continuous drying. The lifting device 5 raises the machine step-by-step, ensuring the top oil-slinging cap is always in the gripping position. The first robotic arm 7 and the second robotic arm 8 overlap their actions, reducing cycle time and improving production efficiency. The turnover rack 6 acts as a temporary buffer, balancing the difference in working rhythm between the two robotic arms. The correction device 62, with position sensor 621 detecting the oil-slinging cap's offset in real time and servo motor 622 performing precise correction, ensures successful assembly of the oil-slinging cap and rotor, improving product qualification rate. This achieves full-process automation, reducing manual intervention, lowering labor requirements and production costs, and improving enterprise economic benefits.

[0020] In one embodiment, the upright 4 is fitted with a support plate 41 for supporting the oil-slinging caps; the support plate 41 can slide up and down on the upright 4 to support the stacked oil-slinging caps, and its height can be adjusted under the action of the lifting device 5. At the same time, the support plate 41 can be made of rubber to avoid damage to the surface of the oil-slinging caps caused by the impact between the surface of the oil-slinging caps and the bottom of the upright 4 when the oil-slinging caps are stacked manually.

[0021] In one embodiment, the lifting device 5 is a step-by-step lifting structure, with each lifting height equal to the height of a single oil slinger cap. It includes a driver 51 located at the bottom of the frame 1 and a lever 52 connected to the piston rod of the driver 51 for lifting the pallet 41. The driver 51 can be a cylinder, a hydraulic cylinder, or an electric actuator. When the piston rod of the driver 51 extends, it drives the lever 52 to move upward. The lever 52 pushes the pallet 41 upward by the height of an oil slinger cap, thereby ensuring that the topmost oil slinger cap on the pallet 41 is always in a suitable gripping position.

[0022] In one embodiment, the correction device 62 includes a position sensor 621 mounted on the turnover frame 6 for detecting the offset state of the oil slinger cap, and a servo motor 622 connected to the positioning groove 61 and driving the oil slinger cap to rotate horizontally to a preset angle according to the signal from the position sensor 621. The position sensor 621 is a photoelectric sensor or a vision sensor, which can detect the position and angular offset of the oil slinger cap placed on the positioning groove 61 in real time. The oil slinger cap is provided with a plurality of positioning holes. When the position sensor 621 does not sense the positioning holes on the oil slinger cap, it sends a signal to the controller 9. The controller 9 sends a rotation command to the servo motor 622, which drives the positioning groove 61 to rotate. When the position sensor 621 senses the positioning holes on the oil slinger cap, the servo motor 622 stops rotating, thereby correcting the position of the oil slinger cap.

[0023] In one embodiment, the turnover frame 6 is located between the first robotic arm 7 and the second robotic arm 8, serving as a buffer positioning area for the oil-slinging cap 5.

[0024] In one embodiment, the first robotic arm 7 and the second robotic arm 8 are provided with a protective cover 10 to prevent debris from falling in and interfering with the operation of the first robotic arm 7 and the second robotic arm 8.

[0025] The first robotic arm 7 and the second robotic arm 8 can be pneumatic grippers or electric grippers, which can synchronously and horizontally transfer the oil slinger cap to the turnover frame 6 or the rotor, or move up and down to accurately grab the oil slinger cap.

[0026] The controller 9 can be a PLC or an industrial control computer, which precisely controls or coordinates the actions of each component through a preset program.

[0027] In use of this utility model, firstly, the operator pre-stacks multiple oil-slinging caps on the upright 4. After the equipment is started, the stepper motor 2 drives the rotary table 3 to rotate, switching the upright 4, which is fully loaded with oil-slinging caps, to the loading station. When the upright 4 moves to the oil-slinging cap loading position, the first robotic arm 7 moves to grab an oil-slinging cap from the top of the upright 4 and place it in the positioning slot 61 of the turnover rack 6. At the same time, the second robotic arm 8 simultaneously grabs the oil-slinging cap that has completed the position correction from the turnover rack 6 and installs it on the rotor.

[0028] Once the oil slinger cap is placed in the positioning slot 61, the position sensor 621 immediately detects its position offset and transmits the signal to the controller 9. The controller 9 controls the servo motor 622 to work according to the signal. The servo motor 622 drives the positioning slot 61 to rotate horizontally with the oil slinger cap to a preset angle, thus completing the position correction.

[0029] Each time the first robotic arm 7 grabs an oil slinger cap, the driver 51 of the lifting device 5 pushes the lever 52 through the piston rod, causing the support plate 41 to lift the oil slinger cap sleeved on the upright 4 to the height of one oil slinger cap, ensuring that the next oil slinger cap is at the top and easy to grab.

[0030] Once all the oil-slinging caps on a pole 4 have been grabbed, the piston rod of the driver 51 of the lifting device 5 retracts, driving the pull rod 52 to reset, thus resetting the support plate 41 on the original pole 4. The stepper motor 2 drives the rotary table 3 to rotate, switching the next pole 4 fully loaded with oil-slinging caps to the feeding station. The operator then reloads the original pole 4 with oil-slinging caps, achieving continuous feeding.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
