Description

Technical Field

[0001] This utility model relates to the technical field of rotor production equipment, and in particular to protective sleeve insertion equipment. Background Technology

[0002] In the field of micro-motor manufacturing, rotors, as core components, are widely used in devices such as electric toothbrushes and high-speed hair dryers. A rotor typically consists of a shaft and a permanent magnet mounted on the shaft, its structure resembling a flat-head screw. The permanent magnet is a hollow cylinder with an outer diameter larger than the outer diameter of the shaft and is fixedly connected to it. During rotor production, to meet the plating requirements of specific locations, a protective sleeve is usually fitted onto the shaft to cover areas that do not require plating. However, after the plating process is completed, the protective sleeve needs to be removed from the shaft for subsequent processing or use. Due to the large production batches of rotors, the traditional method of manually inserting protective sleeves is inefficient and time-consuming, making it difficult to meet the needs of large-scale production. Therefore, there is an urgent need for equipment capable of automating the insertion of protective sleeves in large quantities.

[0003] While some automated equipment exists for assembling small parts, it is often complex in structure and expensive. Furthermore, when handling specially shaped and precisely sized components such as rotors and protective sleeves, it is prone to problems like inaccurate positioning and unstable insertion. In addition, protective sleeves tend to stack during transport due to high friction, making it impossible to transport and insert them smoothly, further increasing the difficulty of automated production. These problems not only affect production efficiency but may also lead to inconsistent product quality, thus limiting the widespread application of related technologies in actual production.

[0004] Therefore, developing an automated device capable of efficiently and accurately completing the rotor protective sleeve insertion process, reducing manual intervention and improving production efficiency, has become a pressing technical challenge in the field of micro-motor manufacturing. This invention aims to overcome the shortcomings of existing technologies and provide a device capable of independently completing large-scale rotor protective sleeve insertion, thereby meeting the high efficiency and high quality requirements of modern industrial production. Utility Model Content

[0005] The purpose of this invention is to provide a protective sleeve insertion device to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective sleeve insertion device includes a machine base, a vibratory feeder, a vibrating plate, an assembly mechanism, and a discharge conveyor belt, wherein:

[0008] The machine base is equipped with a pair of symmetrically arranged linear modules, each with a vibratory feeder at its output end. The linear modules drive the vibratory feeders to move back and forth along the module via screw transmission, evenly distributing the rotor or protective sleeve into the receiving slots on the vibratory feeder. The vibratory feeders are used to transport the rotor and the protective sleeve respectively, with one side of the vibratory feeder responsible for transporting the rotor and the other side responsible for transporting the protective sleeve.

[0009] Furthermore, the vibrating plate is positioned below the vibrating disk and is driven by a vibrator for vibration conveying. The vibrating plate has staggered receiving slots, and a through hole is provided at the output rear end of each receiving slot near the assembly mechanism. The width of the through hole is smaller than the diameter of the top end of the protective sleeve and the diameter of the permanent magnet, ensuring that one end of the rotor or protective sleeve can extend vertically downwards through the through hole, while preventing the rotor or protective sleeve from falling off during vibration. The vibration frequency of the vibrating plate is adjusted by the vibrator to accommodate the feeding requirements of rotors and protective sleeves of different sizes.

[0010] Specifically, the assembly mechanism is located in the middle of the machine base and is used to insert the rotor and protective sleeve. The assembly mechanism's specific structure includes a frame, a first guide rail assembly, a crossbar, a lifting positioning frame, and a finger cylinder. The frame is fixed to the machine base as a support frame, the first guide rail assembly is mounted on the frame, and the crossbar is slidably connected to the frame via the first guide rail assembly. A horizontal drive motor controls the crossbar's forward and backward movement via a screw and threaded seat, achieving precise horizontal positioning of the assembly mechanism. A pair of mounting plates are provided at the bottom of the crossbar, and a second guide rail assembly is mounted on the inner wall of the mounting plates. The lifting positioning frame is slidably connected to the mounting plates via the second guide rail assembly. The lifting drive motor controls the lifting positioning frame's up and down movement via a screw and threaded seat, thereby completing the vertical positioning of the assembly mechanism.

[0011] Furthermore, the lifting and positioning frame is staggered with multiple finger cylinders at its front and rear. These finger cylinders are located at the bottom of the lifting and positioning frame and are used to clamp the rotor and insert it into the protective sleeve. Adjacent finger cylinders are arranged on the front and back of the lifting and positioning frame to reduce spacing and improve space utilization. The clamping action of the finger cylinders is achieved through a pneumatic control system, and the clamping force can be adjusted according to the material characteristics of the rotor and the protective sleeve to avoid damaging the workpiece surface.

[0012] Specifically, a pair of sheet metal parts are fixedly installed at the vibrating plate for transferring the protective sleeves, and a blocking line is fixedly installed between the sheet metal parts. The height and position of the blocking line are designed according to the size of the protective sleeves to control the falling of the stacked protective sleeves and ensure that each protective sleeve can lie independently on the placement slot. The combination of the vibration frequency of the vibrating plate and the design of the blocking line effectively solves the problem of the protective sleeves stacking during vibration and improves the stability of equipment operation.

[0013] Furthermore, the discharge conveyor belt is positioned below the assembly mechanism to transport the assembled rotors. The assembly mechanism uses finger cylinders to grip the rotors, which are fitted with protective sleeves, moves them above the discharge conveyor belt, and then releases the grip to complete the finished product discharge. The operating speed of the discharge conveyor belt is matched with the working rhythm of the assembly mechanism to ensure continuous delivery of finished products and efficient production.

[0014] S1. During the material conveying stage, the linear module controls the vibratory plate to move back and forth, evenly distributing the rotor and protective sleeve to the receiving slots of the vibratory plates on both sides. The vibratory plates are driven by vibrators to vibrate, gradually bringing the rotor and protective sleeve closer to the central assembly mechanism.

[0015] S2. During the insertion operation, the finger cylinder in the assembly mechanism clamps the rotor from one side of the vibrating plate, moves it to the other side of the vibrating plate, and inserts the rotor into the protective sleeve that is vertically clamped on the vibrating plate. After insertion, the finger cylinder holds the rotor with the protective sleeve, moves it above the discharge conveyor belt, and releases the clamp to complete the finished product conveying.

[0016] S3. In the anti-stacking function stage, the design of sheet metal parts and blocking lines effectively prevents the protective sleeves from stacking during vibration, ensuring that each protective sleeve can lie independently on the placement slot, thereby ensuring the smooth progress of the insertion operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The technical advantages of this invention are reflected in several aspects. First, through the coordinated operation of the linear module, vibratory feeder, vibratory plate, and assembly mechanism, automated insertion of the rotor and protective sleeve is achieved, significantly reducing manual intervention. Second, the equipment can process multiple rotors and protective sleeves simultaneously, meeting the needs of mass production. Third, the precise clamping and movement of the finger cylinders ensures the insertion quality of the rotor and protective sleeve, avoiding errors caused by human operation. Finally, the design of the sheet metal parts and blocking lines effectively solves the problem of protective sleeve stacking, improving the stability of equipment operation. In addition, the staggered arrangement of the finger cylinders reduces the spacing between components, improves the compactness of the overall structure, and enables the equipment to achieve efficient production operations within a limited space.

[0019] In summary, this utility model, through innovative structural design and automated control technology, achieves efficient connection between the rotor and the protective sleeve, significantly improving production efficiency and product quality, and has broad application prospects.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0030] A protective sleeve insertion device is disclosed, which automates the efficient insertion of the rotor and protective sleeve, and is suitable for the field of micro-motor manufacturing. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the overall structure of the protective sleeve insertion device includes a machine base, a vibratory feeder 1, a vibrating plate 2, an assembly mechanism 3, and a discharge conveyor belt 15. A pair of symmetrically arranged linear modules 4 are installed on the machine base, with a vibratory feeder 1 mounted at the output end of each linear module 4. The linear modules 4 drive the vibratory feeder 1 to move in the back-and-forth direction via a screw drive, evenly distributing the rotor or protective sleeve onto the vibrating plates 2 on both sides. One side of the vibratory feeder 1 is responsible for conveying the rotor, while the other side is responsible for conveying the protective sleeve. The design of the vibratory feeder 1 ensures stable material conveying during vibration, preventing material scattering or damage due to excessive vibration amplitude.

[0032] Vibrating plate 2 is positioned below vibrating disk 1 and is driven by a vibrator for vibration conveying. Vibrating plate 2 has multiple staggered accommodating slots to accommodate rotors or protective sleeves. A through-hole is located at the rear end of each accommodating slot near assembly mechanism 3. The width of the through-hole is smaller than the diameter of the top end of the protective sleeve and the diameter of the permanent magnet, ensuring that one end of the rotor or protective sleeve can pass through the through-hole and extend vertically downwards, while preventing the workpiece from falling off during vibration. The vibration frequency of vibrating plate 2 is adjusted by the vibrator to accommodate the feeding requirements of rotors and protective sleeves of different sizes. The vibration action of vibrating plate 2 allows the rotor and protective sleeve to gradually move towards the central assembly mechanism 3 in a horizontal position until they reach the through-hole and transition to a vertical position.

[0033] Assembly mechanism 3 is located in the middle of the machine base and is used to perform the insertion operation between the rotor and the protective sleeve. For example... Figure 2 and Figure 3 As shown, the assembly mechanism 3 includes a frame 5, a first guide rail assembly 6, a crossbar 8, a lifting and positioning frame 14, and a finger cylinder 12. The frame 5 is fixed to the machine base as a support frame. The first guide rail assembly 6 is installed on the frame 5, and the crossbar 8 is slidably connected to the frame 5 through the first guide rail assembly 6. The horizontal drive motor 10 controls the crossbar 8 to move back and forth through a screw and a threaded seat, thereby achieving precise positioning of the assembly mechanism 3 in the horizontal direction. A pair of mounting plates 7 are provided at the bottom of the crossbar 8. A second guide rail assembly 11 is installed on the inner side wall of the mounting plate 7, and the lifting and positioning frame 14 is slidably connected to the mounting plate 7 through the second guide rail assembly 11. The lifting drive motor 9 controls the lifting and positioning frame 14 to move up and down through a screw and a threaded seat, thereby completing the positioning of the assembly mechanism 3 in the vertical direction.

[0034] Multiple finger cylinders 12 are staggered at the front and back of the lifting and positioning frame 14. The finger cylinders 12 are located at the bottom of the lifting and positioning frame 14 and are used to clamp the rotor and insert it into the protective sleeve. Adjacent finger cylinders 12 are arranged on the front and back of the lifting and positioning frame 14 to reduce spacing and improve space utilization. The clamping action of the finger cylinders 12 is achieved through a pneumatic control system, and the clamping force can be adjusted according to the material characteristics of the rotor and the protective sleeve to avoid damaging the workpiece surface. The design of the finger cylinders 12 can meet the needs of simultaneous insertion at multiple workstations, further improving production efficiency.

[0035] A pair of sheet metal parts 16 are fixedly installed at the vibrating plate 2 for transferring the protective sleeves, and a blocking line 17 is fixedly installed between the sheet metal parts 16. The height and position of the blocking line 17 are designed according to the size of the protective sleeves to control the falling of the stacked protective sleeves and ensure that each protective sleeve can lie independently on the placement slot. Figure 4 As shown, the vibration frequency of the vibrating plate 2, combined with the design of the blocking line 17, effectively solves the problem of protective sleeves stacking during vibration, thus improving the stability of equipment operation. When protective sleeves stack during vibration, the blocking line 17 restricts the movement of the stacked parts, causing the stacked protective sleeves to gradually separate and lie flat on the placement groove.

[0036] The discharge conveyor belt 15 is positioned below the assembly mechanism 3 to transport the assembled rotors. The assembly mechanism 3 uses finger cylinders 12 to grip the rotors, which are fitted with protective sleeves, and moves them above the discharge conveyor belt 15 before releasing the grip, thus completing the finished product transport. The operating speed of the discharge conveyor belt 15 is matched to the working rhythm of the assembly mechanism 3 to ensure continuous transport and efficient production of finished products. The design of the discharge conveyor belt 15 takes into account the weight and size of the finished products and is made of non-slip material to prevent the finished products from sliding or tipping over during transport.

[0037] S1. In the material conveying stage, the linear module 4 controls the vibratory plate 1 to move back and forth, evenly distributing the rotor and protective sleeve to the receiving slots of the vibratory plates 2 on both sides. The vibratory plates 2 are driven by vibrators to vibrate, gradually bringing the rotor and protective sleeve closer to the central assembly mechanism 3. During this process, the vibration frequency of the vibratory plates 2 is precisely adjusted to ensure that the rotor and protective sleeve can be fed smoothly in the receiving slots until they reach the through hole position and turn into a vertical state.

[0038] S2. During the insertion operation, the finger cylinder 12 in the assembly mechanism 3 clamps the rotor from one side of the vibrating plate 2, moves it to the other side of the vibrating plate 2, and inserts the rotor into the protective sleeve vertically clamped on the vibrating plate 2. After insertion, the finger cylinder 12, holding the rotor with the protective sleeve, moves it above the discharge conveyor belt 15 and releases the clamp, completing the finished product conveying. The movement of the finger cylinder 12 is precisely controlled by the pneumatic control system to ensure the accuracy and stability of each insertion operation.

[0039] S3. In the anti-stacking function stage, the design of sheet metal part 16 and blocking line 17 effectively prevents the protective sleeves from stacking during vibration, ensuring that each protective sleeve can lie independently on the placement slot, thereby ensuring the smooth progress of the insertion operation. The vibration frequency of the vibrating plate 2 combined with the height design of the blocking line 17 ensures that the protective sleeves always maintain a single-layer arrangement during vibration, avoiding insertion failure or equipment failure caused by stacking.

[0040] The technical advantages of this invention are reflected in several aspects. First, through the coordinated operation of the linear module 4, vibratory plate 1, vibratory plate 2, and assembly mechanism 3, automated insertion of the rotor and protective sleeve is achieved, significantly reducing manual intervention. Second, the equipment can process multiple rotors and protective sleeves simultaneously, meeting the needs of mass production. Third, the precise clamping and movement of the finger cylinders 12 ensures the insertion quality of the rotor and protective sleeve, avoiding errors caused by human operation. Finally, the design of the sheet metal parts 16 and the blocking lines 17 effectively solves the problem of protective sleeve stacking, improving the stability of equipment operation. In addition, the staggered arrangement of the finger cylinders 12 reduces the spacing between components, improves the compactness of the overall structure, and enables the equipment to achieve efficient production operations within a limited space.

[0041] In summary, this utility model, through innovative structural design and automated control technology, achieves efficient insertion of the rotor and protective sleeve, significantly improving production efficiency and product quality, and has broad application prospects. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
