Description

Technical Field

[0001] The utility model relates to the technical field of equipment part assembly, and particularly relates to a device for automatically feeding PIN pins of a stator coil of a brushless motor. Background Technique

[0002] The PIN pin of the stator coil of a brushless motor is a metal pin used to connect the stator coil and an external circuit. In a brushless motor, the stator coil usually needs to be connected to an external power supply or a control circuit to enable the normal operation of the motor. The role of the PIN pin is to provide a reliable electrical connection point to allow current to pass through the stator coil smoothly.

[0003] However, in the existing part assembly work process, when installing PIN pins on the stator coil of a brushless motor, the feeding method used is to complete it with the aid of a cylinder gripper mechanism. However, this mechanism can only grasp and feed 1 PIN pin each time, which means that the number of PIN pins that can be fed per unit time is very small, resulting in a slow progress of the entire feeding process, low work efficiency, and inability to meet production requirements. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a device for automatically feeding PIN pins of a stator coil of a brushless motor, which can solve the problem that in the existing part assembly work process, only 1 PIN pin can be grasped and fed each time through the cylinder gripper mechanism, resulting in a slow progress of the feeding process and low work efficiency. It can feed 3 PIN pins at a time, greatly increasing the number of pins fed per unit time, significantly improving production efficiency, and the entire process realizes high automation through the coordinated action of multiple components, thereby improving the assembly accuracy and quality.

[0006] Technical Solution

[0007] To achieve the above object, the utility model provides the following technical solution: A device for automatically feeding PIN pins of a stator coil of a brushless motor, including a base, on the upper surface of the base is provided a vibratory bowl feeder assembly for feeding materials. One side of the vibratory bowl feeder assembly is connected with a feeding track, on the upper surface of the feeding track is fixedly installed a sensor. One side of the vibratory bowl feeder assembly is provided with a cutting component for transferring materials, and one side of the cutting component is connected with a blowing component for pushing materials;

[0008] One side of the blowing component is provided with a feeding component for transporting materials to the pressing position, and one side of the feeding component is provided with a pressing component for pressing the materials.

[0009] Through the above technical solution, when installing the PIN pin body on the stator coil of the brushless motor, first, the feeding assembly of the vibrating disk is used for feeding. When the sensor detects the PIN pin body conveyed by the feeding assembly of the vibrating disk, it will send a signal to the control system. After receiving the signal, the control system controls the cutting assembly to start running. The cutting assembly pushes the PIN pin body to the blowing and conveying position. Immediately afterwards, the blowing assembly uses air flow to stably and accurately convey the PIN pin body to the designated position. Then, the feeding assembly runs to accurately align the stator coil with the PIN pin body. After the alignment is completed, the three PIN pin bodies are press-fitted with the stator coil through the press-fitting assembly.

[0013] Through the above technical solution, when the sensor detects the PIN pin body conveyed by the feeding track, it will send a signal to the control system. After receiving the signal, the control system controls the cutting cylinder to start running. The cutting cylinder controls the support seat to move to the end of the feeding track, so that the PIN pin body enters the inside of the storage groove, and then the PIN pin body is pushed to the blowing and conveying position through the support seat.

[0014] Furthermore, the blowing assembly includes a control cylinder, a clamping jaw is arranged on one side of the control cylinder, an air passage is opened inside the clamping jaw, the clamping jaws are symmetrically distributed about the longitudinal center line of the support seat, and a guide block is connected to one side of one of the clamping jaws.

The function of this blowing circuit is to use air flow to stably and accurately convey the PIN pin body to the designated position.

[0016] Furthermore, the feeding component includes a second guide rail. An upper feeding cylinder is fixedly installed at the upper end of the second guide rail. A sliding seat is connected to the lower end of the feeding cylinder. The sliding seat is slidably connected to the second guide rail. A feeding pipe is connected to the end of the sliding seat. A feeding port is opened at the upper end of the feeding pipe. A nozzle is connected to the lower end of the feeding pipe.

[0018] Furthermore, three feeding pipes are provided, and a blowing valve is installed on the outer surface of the feeding pipes.

[0019] Through the above technical solution, after the blowing valve is opened, a strong air flow blows the three PIN needle bodies along the blowing circuit inside the feeding pipe to the position where they are press-fitted with the stator coil, preparing for the subsequent press-fitting process.

[0020] Furthermore, the press-fitting component includes a guide seat. A press-fitting cylinder is fixedly installed on one side of the guide seat. A sliding table is connected to one end of the press-fitting cylinder. The sliding table is slidably connected to the guide seat. A clamping tooling is fixedly installed on the lower surface of the sliding table.

[0021] Through the above technical solution, the press-fitting cylinder drives the clamping tooling to move up and down, thereby adjusting the position of the clamping tooling.

[0022] Furthermore, a stator coil is connected to the lower end of the clamping tooling, and pins are arranged inside the stator coil.

[0023] Through the above technical solution, the clamping tooling can drive the stator coil to move to the press-fitting position, so that the three PIN needle bodies are respectively inserted into the pins arranged inside the stator coil.

[0024] Compared with the prior art, the present utility model provides a device for automatically feeding PIN needles for a brushless motor stator coil, having the following beneficial effects:

[0025] In the present utility model, the vibrating disk feeding assembly can continuously supply the PIN needle body. When the sensor detects the PIN needle body conveyed by the vibrating disk feeding assembly, it will send a signal to the control system. After receiving the signal, the control system controls the cutting component to start running. The cutting component pushes the PIN needle body to the blowing and conveying position. Immediately afterwards, the blowing component uses air flow to stably and accurately convey the PIN needle body to the designated position. Then the feeding component runs, enabling the stator coil to be precisely aligned with the PIN needle body. After the alignment is completed, three PIN needle bodies are press-fitted with the stator coil through the press-fitting component. By feeding 3 PIN needle bodies at one time, the number of parts fed per unit time is greatly increased, significantly improving the production efficiency. Moreover, the entire process realizes a high degree of automation through the coordinated operation of multiple components, thereby improving the assembly accuracy and quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1-7 , the present utility model provides a technical solution: a device for automatically feeding PIN pins of a brushless motor stator coil, including a base 1. A vibratory bowl feeder assembly is arranged on the upper surface of the base 1 for feeding. One side of the vibratory bowl feeder assembly is connected with a feeding track 5. A sensor 6 is fixedly installed on the upper surface of the feeding track 5. A cutting component is arranged on one side of the vibratory bowl feeder assembly for transferring materials. One side of the cutting component is connected with a blowing component for pushing the materials;

[0036] A feeding component is arranged on one side of the blowing component for transporting the materials to the pressing position. A pressing component is arranged on one side of the feeding component for pressing the materials.

[0037] It is worth mentioning that when it is necessary to install the PIN pin body 12 on the brushless motor stator coil 28, first, the vibratory bowl feeder assembly is used for feeding. When the sensor 6 detects the PIN pin body 12 conveyed by the vibratory bowl feeder assembly, it will send a signal to the control system. After receiving the signal, the control system controls the cutting component to start running. The cutting component pushes the PIN pin body 12 to the blowing and conveying position. Immediately afterwards, the blowing component uses air flow to stably and accurately convey the PIN pin body 12 to the designated position. Then the feeding component runs to make the stator coil 28 and the PIN pin body 12 accurately aligned. After the alignment is completed, the three PIN pin bodies 12 and the stator coil 28 are pressed by the pressing component.

[0038] Please refer to Figures 1-4 , the vibratory bowl feeder assembly includes a chassis 2. A vibrating seat 3 is connected to the upper surface of the chassis 2. A hopper 4 is connected to the upper end of the vibrating seat 3. The cutting component includes a cutting cylinder 7. One end of the cutting cylinder 7 is connected with a slider 8. A first guide rail 9 is fixedly connected to the upper surface of the cutting cylinder 7. The slider 8 is slidably connected to the first guide rail 9. A support seat 10 is fixedly connected to the upper surface of the slider 8. A storage groove 11 is opened inside the support seat 10. The PIN pin body 12 is placed inside the storage groove 11.

[0039] The principle of feeding and cutting the PIN pin body 12 is as follows: A large number of PIN pin bodies 12 are placed in the hopper 4. Through the vibration of the vibration base 3 and the specific track design of the hopper 4, the PIN pin bodies 12 will be arranged in a certain direction and order, and the PIN pin bodies 12 will be transported out one by one, so that the PIN pin bodies 12 are transported into the feeding track 5 one by one. When the sensor 6 detects the PIN pin body 12 transported out of the feeding track 5, it will send a signal to the control system. After receiving the signal, the control system controls the cutting cylinder 7 to start running. The cutting cylinder 7 controls the slider 8 to move, so that the slider 8 drives the support seat 10 to move to the end of the feeding track 5, and then the PIN pin body 12 enters the inside of the storage tank 11. During this process, the first guide rail 9 will guide the movement of the slider 8, and then the cutting cylinder 7 will push the slider 8 to move, so that the PIN pin body 12 inside the support seat 10 is pushed to the blowing and conveying position.

[0040] Please refer to Figures 1-4 , the blowing component includes a control cylinder 13. One side of the control cylinder 13 is provided with a clamping jaw 14.

One side of one of the clamping jaws 14 is connected with a guide block 16.

[0041] The principle of blowing is as follows: After receiving the instruction, the control cylinder 13 drives the two clamping jaws 14 to move, so that the two clamping jaws 14 are closed. The air passage 15 opened inside the clamping jaws 14 and the storage tank 11 opened inside the support seat 10 form a closed blowing circuit, and the guide block 16 can guide the movement of the PIN pin body 12. Then, the PIN pin body 12 can be stably and accurately transported to the designated position through the air flow.

The lower end of the feeding pipe 20 is connected with a nozzle 22. There are three feeding pipes 20, and a blowing valve 23 is installed on the outer surface of the feeding pipe 20.

[0043] The principle of feeding is as follows: After receiving the instruction, the feeding cylinder 17 starts to push the sliding seat 18 downward, and the second guide rail 19 guides the movement of the sliding seat 18. The sliding seat 18 drives the nozzle 22 at the lower end of the feeding pipe 20 to move synchronously, so that the nozzle 22 is accurately aligned with the stator coil 28 below, thereby ensuring the precise connection between the subsequent PIN needle body 12 and the stator coil 28. When the nozzle 22 moves to the designated position, the air blowing valve 23 is opened, and a strong air flow blows the 3 PIN needle bodies 12 along the air blowing circuit inside the feeding pipe 20 to the position where they are press-fitted with the stator coil 28, preparing for the subsequent press-fitting process.

[0044] Please refer to Figures 1-7 , the press-fitting assembly includes a guide seat 24. One side of the guide seat 24 is fixedly installed with a press-fitting cylinder 25. One end of the press-fitting cylinder 25 is connected with a sliding table 26. The connection mode between the sliding table 26 and the guide seat 24 is a sliding connection. The lower surface of the sliding table 26 is fixedly installed with a clamping tool 27. The lower end of the clamping tool 27 is connected with a stator coil 28. The inside of the stator coil 28 is provided with pins 29;

[0045] The principle of press-fitting the PIN needle body 12 and the stator coil 28 is as follows: The press-fitting cylinder 25 drives the sliding table 26 to rise, and the guide seat 24 guides the movement of the sliding table 26. The sliding table 26 drives the stator coil 28 to rise synchronously through the clamping tool 27, so that the 3 PIN needle bodies 12 are respectively inserted into the pins 29 arranged inside the stator coil 28, thereby completing the press-fitting work of the PIN needle body 12 and the stator coil 28.
