[0030] In view of the technical problems described in the background art, such as Figure 1-11As shown, a vision-based automatic feeding machine for injection-molded fan blade shafts is provided, comprising: a frame 1 for mounting and supporting mechanical components; a vibratory feeder 2 mounted on the frame 1 for holding the shaft; a support frame 3 mounted on the frame 1 and positioned in front of the discharge port of the vibratory feeder 2; and a receiving block 4 mounted on the support frame 3, the receiving block 4 having one or more first receiving positions 5 for accommodating the shaft. The first receiving position 5 is provided with a channel 6 that connects to the discharge port of the vibratory feeder 2; a detection element 7 is provided at the end of the channel 6 away from the vibratory feeder 2, the detection element 7 being used to detect the shaft core's arrival; a material distribution block 8 is disposed on one side of the receiving block 4, and the material distribution block 8 has one or more second receiving positions 9 for accommodating the shaft core; a Y-axis moving module 10 is mounted on the support frame 3 and positioned above the receiving block 4 and the material distribution block 8, the Y-axis moving module... Group 10 is used to move the Z-axis drive module 11 along the Y-axis. The Z-axis drive module 11 is mounted on the Y-axis moving module 10. The Z-axis drive module 11 includes a Z-axis cylinder 12, a rotary cylinder 13 connected to the Z-axis cylinder 12, and a suction nozzle 14 disposed on the rotary cylinder 13. The suction nozzle 14 is used to pick up the shaft core. A vision device 15 is mounted on one side of the receiving block 4 and is used to identify the front and back of the shaft core on the suction nozzle 14. The system includes: a feeding device 16, which is mounted on the material distribution block 8 and is used to feed the shaft core of the material distribution block 8; a discharging device 17, which is mounted on the frame 1 and includes a discharging frame 18 and a discharging head 19 disposed on the discharging frame 18; there is one or more discharging heads 19, which are connected to the material distribution block 8 through pipes; and a control system 20, which is used to receive and output signals.

[0031] The frame 1, serving as the basic support structure of the entire feeding machine, is constructed from high-strength metal materials (such as aluminum alloy profiles) through welding or bolting, providing sufficient stability and rigidity. Adjustable feet are installed at its bottom to adjust the levelness of the frame 1, ensuring the stability of the entire equipment during operation. Multiple mounting holes and slots are pre-drilled on the frame 1 to facilitate the installation and securing of other mechanical components.

[0032] The vibratory feeder 2 is installed at a specific position on the frame 1 and is tightly connected to the frame 1 by bolts. The vibratory feeder 2 has an internal spiral track for placing the shaft cores to be fed. The vibratory feeder 2 vibrates via a vibratory motor, causing the shaft cores to move upwards in an orderly manner along the spiral track, eventually reaching the discharge port of the vibratory feeder 2. The vibration frequency and amplitude of the vibratory feeder 2 can be adjusted via a control panel to accommodate the feeding requirements of shaft cores of different specifications and shapes. Details not related to this invention will not be elaborated further.

[0033] The support frame 3 is also made of metal and is fixed to the frame 1 with bolts, located in front of the discharge port of the vibratory feeder 2. The support frame 3 has a reasonable structural design and sufficient strength to support other components such as the receiving block 4, the distributing block 8, and the Y-axis moving module.

[0034] The receiving block 4 is mounted on the support frame 3, and has one or more first receiving positions 5 for accommodating the shaft core. Preferably, there is only one first receiving position 5, which is connected to the discharge pipe of the vibratory feeder 2. The first receiving position 5 is provided with a channel 6, which is tightly connected to the discharge port of the vibratory feeder 2 to ensure that the shaft core can smoothly enter the channel 6 of the receiving block 4 from the vibratory feeder 2. When the vibratory feeder 2 conveys the shaft core to the discharge port, the shaft core enters the first receiving position 5 along the channel 6. A detection element 7 is provided at the end of the channel 6 away from the vibratory feeder 2. When the shaft core reaches this position, the detection element 7 will detect that the shaft core is in place and feed the signal back to the control system 20.

[0035] The material distribution block 8 is located on one side of the receiving block 4, and has one or more second receiving positions 9 for accommodating the shaft cores. Preferably, there are 8 second receiving positions 9, which can support the production of 1 to 8 cavities in one mold. The function of the material distribution block 8 is to temporarily store and distribute the shaft cores transferred from the receiving block 4 for subsequent loading operations.

[0036] The Y-axis moving module is mounted on the support frame 3 and positioned above the receiving block 4 and the distributing block 8. The Y-axis moving module 10 is used to drive the Z-axis drive module 11 to move the shaft core between the receiving block 4 and the distributing block 8.

[0037] The Z-axis drive module is mounted on the Y-axis slide of the Y-axis moving module. It includes a Z-axis cylinder, a rotary cylinder 13 connected to the Z-axis cylinder, and a suction nozzle 14 mounted on the rotary cylinder 13. When the Y-axis moving module moves the Z-axis drive module to the appropriate position, the Z-axis cylinder activates, pushing the rotary cylinder 13 and the suction nozzle 14 downwards, bringing the suction nozzle 14 closer to the shaft core. The suction nozzle 14 is connected to an external vacuum device, and it sucks up the shaft core through vacuum adsorption. Then, the Z-axis cylinder drives the suction nozzle 14 and the shaft core upwards. If it is necessary to adjust the front and back of the shaft core, the rotary cylinder 13 can rotate the suction nozzle 14 and the shaft core to meet subsequent feeding requirements.

[0038] The function of the vision device 15 is as follows: after the suction nozzle 14 picks up the shaft core, the vision device 15 takes a picture of the shaft core on the suction nozzle 14 and feeds the captured image information back to the control system 20. The control system 20 analyzes and processes the image to identify the front and back of the shaft core, and controls the rotary cylinder 13 of the Z-axis drive module to adjust the shaft core according to the identification result.

[0039] The pushing device 16 pushes the shaft core on the second receiving position 9 to the discharging device 17. The discharging device 17 is mounted on the frame 1 and includes a discharging rack 18 and one or more discharging heads 19 disposed on the discharging rack 18. The discharging heads 19 can be configured according to the number of mold cavities, for example, 1 to 8. The discharging heads 19 are connected to the material distribution block 8 through pipes. After the pushing device 16 pushes the shaft core to the pipe on the discharging head 19, the shaft core is transported along the pipe to the subsequent processing equipment, completing the entire feeding process. Under the action of an external robotic arm, the shaft core on the discharging device 17 is transferred into the injection mold cavity.

[0040] The control system 20 uses a programmable logic controller (PLC) as its core control unit. It receives signals from components such as the detection element 7 and the industrial camera 27, analyzes and processes these signals according to a preset program, and then outputs control signals to actuators such as the Y-axis motor, Z-axis cylinder, rotary cylinder 13, and pusher cylinder 29 to achieve automated control of the entire loading machine. Simultaneously, the control system 20 is also equipped with a human-machine interface (HMI), allowing operators to set and adjust the equipment's operating parameters and monitor its operational status.

[0041] The specific working process is as follows: The vibratory feeder 2 is started, and the shaft core is placed inside. The vibratory feeder 2 vibrates, causing the shaft core to move upwards along a spiral track, eventually reaching the discharge port and entering the channel 6 of the receiving block 4. After the detection component 7 detects the shaft core's position, it sends a signal back to the control system 20. The control system 20 controls the Y-axis moving module to move the Z-axis drive module to the corresponding position above the receiving block 4. The Z-axis cylinder pushes the suction nozzle 14 downwards to pick up the shaft core, and then upwards. The industrial camera 27 takes a picture of the shaft core on the suction nozzle 14 and sends the image information back to the control system 20, which identifies the front and back of the shaft core. If the front and back of the shaft core do not meet the requirements, the control system 20 controls the rotary cylinder 13 to rotate and adjust the shaft core. If mixed materials occur, they are collected at the defective product placement position under the movement of the Y-axis moving module 10. The Y-axis moving module moves the Z-axis drive module above the distribution block 8, and the suction nozzle 14 places the shaft core in the second receiving position 9 of the distribution block 8. When feeding is required, the pusher cylinder 29 pushes the pusher tube 31 to push the shaft core on the material distribution block 8 to the pipe on the discharge head 19 to complete the feeding operation.

[0042] The vibratory feeder 2 automatically sorts and feeds materials, and works with the Y / Z axis module, rotary cylinder 13 and suction nozzle 14 to achieve automatic picking and placing. Combined with visual recognition and pneumatic pushing, it completely replaces manual operation and improves production efficiency, especially suitable for high-cycle production needs of multi-cavity molds (1-8 pieces). Precise anti-misplacement: The industrial camera 27 identifies the front and back of the shaft core in real time. The control system 20 is linked with the rotary cylinder 13 to ensure that the shaft core is placed in the correct orientation at the material distribution position, solving the technical pain point of easy reverse placement by manual placement.

[0043] like Figure 8-9 As shown, the channel 6 of the receiving block 4 is provided with a cover plate 21. The upper and lower end faces of the cover plate 21 are respectively provided with through grooves 22, which are used to accommodate shaft cores of different thicknesses. The channel 6 is provided with a cover plate 21, and the upper and lower end faces of the cover plate 21 are respectively provided with through grooves 22. These through grooves 22 are designed with different dimensions to accommodate shaft cores of different thicknesses, improving the versatility of the equipment. Different groove depths of through grooves 22 are selected according to the different shaft core thicknesses to meet the requirements of multiple mold specifications.

[0044] like Figure 10 As shown, the Y-axis moving module 10 includes a Y-axis motor 23, a Y-axis lead screw 24 connected to the output end of the Y-axis motor 23, a Y-axis guide rail 25 arranged parallel to the Y-axis lead screw 24, and a Y-axis slide block 26 cooperating with the Y-axis guide rail 25; the Y-axis slide block 26 is sleeved on the Y-axis lead screw 24 through a lead screw nut; wherein, the Y-axis motor 23 drives the Y-axis slide block 26 to move along the Y-axis guide rail.

[0045] The driving process is as follows: After the Y-axis motor starts, it drives the Y-axis lead screw to rotate through the output shaft. Since the Y-axis slide is connected to the Y-axis lead screw through the lead screw nut and cooperates with the Y-axis guide rail, the Y-axis slide will move linearly along the Y-axis guide rail under the rotation of the Y-axis lead screw, thereby realizing the movement function in the Y-axis direction and driving the Z-axis drive module 11 to move along the Y-axis.

[0046] refer to Figure 4 As shown, the vision device 15 includes an industrial camera 27 mounted on the left side of the receiving block 4 and a light source 28 mounted on the right side of the distributing block 8; the industrial camera 27 is used to take pictures of the shaft core sucked by the suction nozzle 14 and feed them back to the control system 20; the light source 28 is used to provide light to the industrial camera 27.

[0047] The industrial camera 27 takes pictures of the shaft core on the nozzle 14 and feeds the captured image information back to the control system 20. The light source 28 provides sufficient light for the industrial camera 27 to ensure that the captured image is clear and accurate. The control system 20 analyzes and processes the image to identify the front and back of the shaft core, and controls the rotary cylinder 13 of the Z-axis drive module to adjust the shaft core according to the identification result.

[0048] Reference Figure 11 As shown, the pushing device 16 includes a pushing cylinder 29 mounted on the support frame 3, a pushing block 30 mounted on the telescopic end of the pushing cylinder 29, and a pushing pipe 31 mounted on the pushing block 30; the pushing pipe 31 is externally connected to a compressed air source, and the pushing cylinder 29 drives the pushing pipe 31 to push the shaft core on the material distribution block 8 to the pipe on the discharge head 19.

[0049] The pushing device 16 includes a pushing cylinder 29, a pushing block 30, and a pushing pipe 31. The pushing pipe 31 is connected to an external compressed air source.

[0050] Operating mode: When a shaft core needs to be fed onto the material distribution block 8, the pusher cylinder 29 is activated, pushing the pusher block 30 and the pusher pipe 31 to move. Under the action of the compressed air source, the pusher pipe 31 generates a certain airflow, which sends the shaft core on the material distribution block 8 to the pipe on the discharge head 19, realizing the feeding operation of the shaft core.

[0051] The discharge head 19 is connected to the discharge frame 18 via a mounting block. The mounting block is provided with an adjustment groove, which is adjustable to the discharge frame 18 via screws, allowing for easy adjustment of the position of the discharge head 19 according to actual needs.

[0052] Preferably, the detection element 7 is a photoelectric sensor or a vacuum sensor.

[0053] The photoelectric sensor can be a through-beam photoelectric sensor. Its principle is as follows: when an object moves onto the optical axis between the transmitter and receiver, the axis blocks the light beam, causing a sharp decrease in the light intensity received by the receiver. The internal circuitry of the receiver detects this change in light intensity and converts it into a change in electrical signal (e.g., from a high level to a low level). This changing electrical signal is transmitted to the control system 20, which determines that the object has reached its position based on the change in the electrical signal.

[0054] The working principle of the vacuum sensor is as follows: When the shaft moves to the position of the detection element 7, during the adsorption process, the capacitance value inside the sensor changes accordingly with the increase of vacuum. The sensor converts the capacitance change into an electrical signal output, and the control system 20 determines whether the object is in position based on the change of the electrical signal. When the object is completely adsorbed, the capacitance value will stabilize at a specific value, and the electrical signal will also stabilize accordingly. The control system 20 confirms that the object is in position based on this.

[0055] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
