Description

Technical Field

[0001] The present invention relates to the technical field of automatic visual detection, in particular to motor shaft size detection equipment. Background Art

[0002] Linear motors and stepper motors enable mobile phones to achieve more complex camera functions, such as optical zoom. The vibration motor is the core component of the phone's tactile feedback function. Without it, users will lose many intuitive feedbacks on operation. The motor shaft needs to withstand the vibration and pressure in daily use, so its design must ensure durability and reliability. High-quality motor shafts can reduce the failure rate and improve the long-term stability of mobile phones.

[0003] Common motor shaft materials include stainless steel, aluminum alloy, copper, titanium alloy, etc. However, conventional metal motor shafts have relatively poor wear resistance, poor corrosion resistance, and will produce certain magnetic field interference and other disadvantages. Ceramic motor shafts are often used in high-end mobile phones because ceramic materials have excellent wear resistance, corrosion resistance, non-magnetic, good insulation, high dimensional thermal stability and other advantages. Therefore, the application of ceramic motor shafts in mobile phones improves the performance and durability of the motor, especially in devices that pursue high-end design and excellent user experience.

[0004] Ceramic motor shafts have high-precision dimensional requirements. For example, a diameter specification of Ф1±0.002mm requires fully automatic dimensional inspection in actual mass production, and the production capacity UPH needs to reach more than 4000. Due to the very high precision requirements, the common AOI turntable inspection machine can meet the production capacity requirements, but because the turntable inspection machine is a multi-station inspection, each station on the turntable rotates to the inspection camera position. There will be a height difference, which changes the working distance of the camera, thereby affecting the measurement results. Therefore, the turntable structure has defects in ultra-high precision inspection.

[0005] Based on this, a motor shaft dimension detection device is now provided, which can eliminate the disadvantages of the existing device. Summary of the invention

[0035] This detection equipment has a simple structure. Compared with traditional disc-type detection equipment, it reduces a set of material unloading and loading modules. At the same time, it adopts PPU loading and unloading, with high loading and unloading efficiency. The UPH can reach 4000. At the same time, compared with the turntable structure, the detection carrier is fixed and has better stability. Compared with traditional disc-type detection equipment, it does not need to rotate each workstation to the detection camera position, avoiding the height difference and achieving higher detection accuracy.

[0036] In one embodiment, the loading assembly 6 includes a circular vibration disk 11, a first base 12, a linear vibrator 13, and a detection optical fiber 14. The first base 12 is fixedly connected to the upper surface of the side frame 3, and the circular vibration disk 11 and the linear vibrator 13 are arranged on the upper surface of the first base 12. The circular vibration disk 11 and the linear vibrator 13 are connected, and the end of the linear vibrator 13 away from the circular vibration disk 11 is fixedly connected to a receiving plate 39, and two symmetrical detection optical fibers 14 are arranged on the side wall of the receiving plate 39, and the detection optical fibers 14 are telecommunication-connected to the controller.

[0037] Pour the motor shaft material into the circular vibration disk 11. To prevent the material from being scratched, Teflon is sprayed on the surface of the circular vibration disk 11. The material moves forward through the circular vibration disk 11 and the linear vibrator 13. The linear vibrator 13 has a double-channel structure and can flow 2 pieces of material to the receiving plate 39 at a time. The two detection optical fibers 14 on the receiving plate 39 can detect the presence or absence of material.

[0038] In one embodiment, the transfer assembly 7 includes a PPU manipulator 22 and a hand gripper 23. The PPU manipulator 22 is fixedly connected to the upper surface of the lower frame 1. Two symmetrical hand grippers 23 are arranged at the output end of the PPU manipulator 22. The hand gripper 23 includes a hand gripper block 24 and a suction nozzle 26.

A suction nozzle 26 is arranged at the bottom of the ventilation plate 25. A spring is fixedly connected between the ventilation plate 25 and the hand gripper block 24. The suction nozzle 26 is connected to an external vacuum generator.

[0039] The detection optical fiber 14 receives the signal command and transmits the signal to the controller. The controller starts the PPU robot 22, and the PPU robot 22 drives the gripper 23 to move. One of the grippers 23 can suck up 2 pieces of materials on the front end receiving plate 39 of the linear vibrator 13, and the other gripper 23 is used to suck up the 2 pieces of materials after the visual inspection.

[0040] In one embodiment, the material classification component 8 includes an electric push rod 29, a second base 30, a sliding plate 31, and a tray plate 34. The second base 30 and the tray plate 34 are fixedly connected to the upper surface of the lower frame 1. A material box groove is opened on the upper surface of the tray plate 34, and six material boxes 33 are placed in the material box groove. A linear guide rail 32 is arranged on the upper surface of the second base 30, and a sliding plate 31 is slidingly arranged in the linear guide rail 32. The side wall of the second base 30 is provided with an electric push rod 29, and the output end of the electric push rod 29 is connected to the sliding plate 31. The sliding plate 31 is provided with six material dividing holes 40 opposite to each other. The material at the front end of the linear vibrator 13 is transferred to the positioning and fixing component 10 below the telecentric lens 37 through the PPU manipulator 22, and the material that has been detected on the positioning and fixing component 10 is simultaneously transferred to the top of the material dividing hole 40, and then the suction nozzle 26 cuts off the air and blows air to complete the unloading and transfer.

[0041] There is a compression spring between the ventilation plate 25 and the gripping block 24 to ensure that the suction nozzle 26 and the motor shaft product are in elastic contact, thereby avoiding damage to the product surface. The suction nozzle is made of PEEK or ceramic.

[0042] In one embodiment, the positioning and fixing assembly 10 includes a positioning frame 15, a backlight source 16, and a backlight source mounting plate 17. The positioning frame 15 is fixedly connected to the upper surface of the lower frame 1. A positioning plate 18 is detachably provided on the upper surface of the positioning frame 15. Two symmetrical support plate grooves 21 are provided on the upper surface of the positioning plate 18. A V-shaped support plate 19 is detachably provided on the inner side wall of the support plate groove 21. The V-shaped support plate 19 is provided with a placement groove 20 corresponding to the shape of the motor shaft.

[0043] The positioning and fixing component 10 is used to place the motor shaft product, and is positioned by two sets of V-shaped support plates 19. The V-shaped support plates 19 are partially hollowed out for lighting by the backlight source 16. A surface light source or a coaxial light source can be used as the backlight.

[0044] In one embodiment, a keyboard placement plate 5 is disposed on the upper surface of the lower frame 1 , and universal wheels and wheel locks are disposed on the lower surface of the lower frame 1 .

[0045] The above embodiment discloses a motor shaft size detection device, and its specific working principle and process are as follows: Pour the motor shaft material into the circular vibration disk 11. To prevent the material from being scratched, Teflon is sprayed on the surface of the circular vibration disk 11. The material moves forward through the circular vibration disk 11 and the linear vibrator 13. The linear vibrator 13 has a double-channel structure and can flow 2 pieces of material to the receiving plate 39 at a time. The two detection optical fibers 14 on the receiving plate 39 can detect the presence or absence of material.

[0046] The detection optical fiber 14 receives the signal command and transmits the signal to the controller. The controller starts the PPU manipulator 22, and the PPU manipulator 22 drives the hand gripper 23 to move. One of the hand grippers 23 can suck up 2 pieces of materials on the front receiving plate 39 of the linear vibrator 13, and the other hand gripper 23 is used to suck up 2 pieces of materials after the visual inspection. The material at the front end of the linear vibrator 13 is transferred to the positioning and fixing component 10 below the telecentric lens 37 through the PPU robot 22, and at the same time, the material that has been inspected on the positioning and fixing component 10 is transferred to the top of the dividing hole 40, and then the suction nozzle 26 is cut off and blown to complete the unloading and transfer.

[0047] There is a compression spring between the ventilation plate 25 and the gripping block 24 to ensure that the suction nozzle 26 and the motor shaft product are in elastic contact, thereby avoiding damage to the product surface. The suction nozzle is made of PEEK or ceramic.

[0048] The positioning and fixing component 10 is used to place the motor shaft product, and is positioned by two sets of V-shaped support plates 19. The V-shaped support plates 19 are partially hollowed out for lighting by the backlight source 16. A surface light source or a coaxial light source can be used as the backlight.

[0049] The hand gripper 23 moves the inspected material to the top of the dividing hole 40, and classifies the material into normal size, larger size and smaller size according to the inspection data of the camera 36. The electric push rod 29 moves, so that the dividing hole 40 can move to the top of the corresponding material box 33. The three dividing holes 40 respectively correspond to the three material boxes 33 below. When the hand gripper 23 disconnects the vacuum blowing, the material is blown into the corresponding dividing hole 40, and enters the corresponding material box 33 below through the dividing hole 40, thereby realizing the classification of the inspected material.

[0050] This device can be applied to the detection of short bars of other materials. It is only necessary to change the gripper 23, the loading assembly 6, and the positioning and fixing assembly 10 according to the size of the bar, and select the camera 36 and the telecentric lens 37 according to the detection accuracy. Since it is a backlight detection, the light source can be universal, and the lighting effect of different materials is relatively consistent.

[0051] This detection equipment has a simple structure. Compared with the traditional disc-type detection equipment, it reduces a set of material transfer modules. At the same time, it adopts PPU transfer, which has high transfer efficiency and UPH can reach 4000. At the same time, compared with the turntable structure, the detection carrier is fixed and has better stability. Compared with the traditional disc-type detection equipment, it does not need to rotate each station to the detection camera position, avoiding the height difference that will occur, and the detection accuracy is higher; The inspected motor shafts can be unloaded and sorted at the same time as loading, which shortens the time interval between unloading and loading, greatly reduces the workload of the staff, and effectively improves production efficiency.

[0052] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
