Description

Technical Field

[0001] This invention relates to the field of camera module manufacturing technology, and more specifically, to a dust removal module and a dust removal device. Background Technology

[0002] Compact camera modules are commonly used electronic components in mobile phones, computers, and other terminal electronic products. Due to their small size, it is difficult to continuously improve the manufacturing yield of compact camera modules. As a crucial component of the camera module, the assembly and manufacturing yield of the motor directly impacts the overall manufacturing yield of the camera module. During the transportation of motor products, since the motor's internal components are often assembled using injection-molded parts, surface burrs or collisions can generate tiny particles in these parts. Since camera modules are active electronic devices that require power to capture images, if these tiny particles contaminate the optical path of the camera module, it will degrade the image quality. These tiny particles may, after optical magnification, cause dark areas in the image. Furthermore, these tiny particles may also affect the motor's mechanical operation, thus affecting its normal operation.

[0003] As can be seen from the above, the existing technology suffers from a low manufacturing yield of camera modules. Summary of the Invention

Detailed Implementation

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0040] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0041] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0042] To address the low manufacturing yield of camera modules in existing technologies, this invention provides a dust removal module and a dust removal device. The dust removal device includes the dust removal module described below.

[0043] In existing technologies, such as Figures 4 to 5As shown, the motor 70 of the camera module is generally a coil-magnet driven type. The motor 70 includes a carrier 71, a base 72, and a magnet 73. The coil is fixed to the carrier 71, and the magnet 73 is fixed to the base 72. When energized, the relative force generated by the magnet 73 and the coil can drive the carrier 71 to move. However, this structure of moving and stationary parts inside the motor 70 may cause the moving parts to vibrate during movement, causing tiny particles originally attached to the surface of the carrier 71 to fall off. The carrier 71 and the base 72 are often molded by injection molding, and for strength requirements, the carrier 71 is generally made of LCP (liquid crystal polymer) material. Because liquid crystal polymers have short molecular chain structures, few cross-linked components, and high crystallinity, tiny particles are very likely to appear on the surface. These tiny particles can easily fall onto the optical path of the camera module during the movement of the motor 70, thus affecting the imaging of the camera module and possibly affecting the mechanical operation of the motor 70, thereby affecting the normal operation of the motor 70.

[0044] Therefore, such as Figures 1 to 2 As shown, this application provides a dust removal module for dust removal from the motor 70 of a camera module. The dust removal module includes a first drive member 11, a jet nozzle 12, and an air supply mechanism. The jet nozzle 12 has a jet port 121 on its peripheral sidewall. The air supply mechanism is connected to the jet nozzle 12 and provides dust removal gas. The first drive member 11 is driven to rotate the jet nozzle 12 within the motor 70 to perform dust removal operations on the motor 70.

[0045] Specifically, such as Figures 4 to 5 As shown, the carrier 71 has a central through hole, and the jet nozzle 121 is located at the bottom end of the jet head 12. The bottom end of the jet head 12 is cylindrical, and the bottom part of the jet head 12 extends into the central through hole of the carrier 71, so that the jet nozzle 121 is located inside the motor 70, thereby performing dust removal operation.

[0046] With the above settings, during the manufacturing process of the camera module, the motor 70 of the camera module will be subjected to rotary air jet dust removal by the jet head 12 that extends into it. This effectively removes the tiny particles inside the motor 70, thereby preventing the tiny particles from affecting the normal operation of the motor 70 or from adhering to the optical path of the camera module and causing a deterioration in the image quality of the camera module, thus greatly improving the manufacturing yield of the camera module.

[0047] Since this application uses a jet injection method that extends into the motor 70, the area of ​​the jet nozzle 121 relative to the motor 70 cannot be made large. By adopting a rotary jet injection method, it is possible to ensure that the airflow generates a large impact force inside the motor 70, thereby improving the dust removal effect.

[0048] In this embodiment, there are multiple jet nozzles 121, which are spaced apart circumferentially along the jet head 12. Furthermore, the multiple jet nozzles 121 are equally spaced circumferentially along the jet head 12. This arrangement allows for more uniform and thorough jetting into the motor 70, thereby expelling as many fine particles as possible and ensuring effective dust removal.

[0049] Furthermore, multiple jet nozzles 121 are symmetrically arranged along the central axis of the jet head 12. This arrangement increases the impact force on various parts of the motor 70 when the dust removal module sprays air. The symmetrical arrangement ensures that when the jet head 12 rotates, the impact-driven gas exerts a greater impact force on all parts of the motor 70, thus achieving more thorough dust removal from the motor 70.

[0050] In this embodiment, there are multiple jet nozzles 121, which are divided into multiple groups along the axial direction of the jet head 12, and the multiple groups of jet nozzles 121 are arranged at intervals. Each group contains one or more jet nozzles 121, and when there are multiple jet nozzles 121 in each group, the multiple jet nozzles 121 in each group are arranged at intervals along the circumference of the jet head 12. That is, the multiple jet nozzles 121 are arranged in multiple rows, one above the other. Through the above arrangement, the jetting area of ​​the jet head 12 can be increased, resulting in a greater impact force on various parts inside the motor 70, thereby achieving a better dust removal effect.

[0051] Furthermore, multiple sets of jet nozzles 121 are staggered along the circumference of the jet head 12, such as... Figure 2 As shown. It can be understood that the above staggered arrangement means that adjacent sets of jet nozzles 121 are not vertically overlapping but staggered. Through the above arrangement, the degree of impact of the dust-collecting gas inside the motor 70 is further improved, so that multiple sets of jet nozzles 121 can be superimposed to create a greater impact force inside the motor 70, thereby improving the dust collection effect.

[0052] In one specific embodiment, the jet head 12 is provided with two sets of jet nozzles 121, one above the other. Each set contains multiple jet nozzles 121, which are spaced apart circumferentially around the jet head 12, and the two sets of jet nozzles 121 are staggered circumferentially around the jet head 12. Furthermore, each jet nozzle 121 extends radially around the jet head 12, that is, it is horizontally positioned. Figure 4 A schematic diagram is shown of the dust removal module performing dust removal operation on the motor 70 in this case. When the jet nozzle 12 extends into the central through hole of the carrier 71 and rotates to spray air, the ejected airflow passes through the gaps in the internal components of the motor and flows out from the bottom of the motor 70, thereby carrying away the fine particles.

[0053] In another specific embodiment, the arrangement of the jet nozzle 121 is different, specifically, as follows: Figure 3 and Figure 5 As shown, the jet nozzle 121 includes a first jet nozzle 1211 and a second jet nozzle 1212. The first jet nozzle 1211 and the second jet nozzle 1212 are spaced apart along the axial direction of the jet head 12, and the second jet nozzle 1212 is closer to the bottom end of the jet head 12 than the first jet nozzle 1211. The second jet nozzle 1212 is inclined upward from the inside out, and the first jet nozzle 1211 extends radially along the jet head 12.

[0054] In other words, the first jet nozzle 1211 is designed to be horizontally through-hole, allowing it to spray air in a horizontal direction. The second jet nozzle 1212 is designed to be angled, allowing it to spray air upwards at an angle. Due to the characteristics of the motor structure, there is a risk of direct interference between the outer surface of the carrier 71 and the base 72 or outer shell in the structural relationship between the moving and stationary parts. Therefore, the outer surface of the carrier 71 is a surface with a higher probability of generating small particles. However, the inner surface of the carrier 71 has a lower risk of generating small particles because the motor 70 will be assembled with the lens and then assembled into a camera module. After the carrier 71 and lens are installed, the inner surface of the carrier 71 and the lens will be fixed with glue. Through the above arrangement, since the jet direction of the second jet nozzle 1212 is upward, it can intersect with the jet of the horizontal first jet nozzle 1211, thereby making the total gas between the second jet nozzle 1212 and the first jet nozzle 1211... Figure 5 The flow pattern shown allows the material to flow from top to bottom into the outer surface of the carrier 71 and other locations, thereby greatly improving the dust removal efficiency.

[0055] Furthermore, there are multiple first jet ports 1211, which are spaced apart circumferentially along the jet head 12. Correspondingly, there are also multiple second jet ports 1212, which are spaced apart circumferentially along the jet head 12.

[0056] like Figure 1 As shown, the dust removal module also includes a rotary joint 13, an upper joint 14, a lower joint 15, and a clamping block 16. The rotary joint 13 is used to connect to components of other modules. The upper joint 14 is connected to both the rotary joint 13 and the first drive member 11, and the lower joint 15 is connected to both the first drive member 11 and the jet head 12. The clamping block 16 is located between the upper joint 14 and the first drive member 11, and is used to tightly connect the first drive member 11.

[0057] In this embodiment, the air pipe of the air supply mechanism can be connected to the rotary joint 13. The rotary joint 13, the upper joint 14, the lower joint 15, the first driving member 11 and the clamping block 16 have an air supply channel that runs from top to bottom. The bottom end of the air supply channel is connected to the jet head 12. Alternatively, the air pipe of the air supply mechanism can pass through the rotary joint 13, the upper joint 14, the lower joint 15, the first driving member 11 and the clamping block 16 from top to bottom, thereby connecting to the jet head 12.

[0058] Furthermore, the first drive component 11 may integrate an air supply mechanism to provide air pressure to the jet head 12.

[0059] In this embodiment, the first driving component 11 is a rotary motor or a cylinder.

[0060] like Figures 6 to 7 As shown, this application also provides a dust removal device, including a frame 20, the aforementioned dust removal module 10, and a moving module 30. The dust removal module 10 is configured in a one-to-one correspondence with the motor 70. The moving module 30 is adjustable in height relative to the frame 20, and the dust removal module 10 is disposed on the moving module 30 to extend into or retract from the motor 70 as the moving module 30 moves up and down.

[0061] like Figure 8 and Figure 10 As shown, the moving module 30 includes a top plate 31, a fixed base 32, and a guide shaft 33. The top plate 31 is connected and fixed to the frame 20. The dust removal module 10 is disposed on the fixed base 32. The bottom end of the guide shaft 33 is connected to the fixed base 32. The top plate 31 is provided with a shaft fixing support 34. The top end of the guide shaft 33 passes through the shaft fixing support 34. The shaft fixing support 34 is used to lock the guide shaft 33 after it has moved a preset distance.

[0062] Specifically, the shaft fixing support 34 includes a base body and a locking fastener. The base body is embedded in the top plate 31 and has a vertical through hole and a horizontal locking hole. The guide shaft 33 passes through the vertical through hole, and the locking fastener extends into the locking hole and abuts against the guide shaft 33, thereby locking the guide shaft 33.

[0063] In this embodiment, there are multiple guide shafts 33, which are spaced apart circumferentially along the fixed base 32.

[0064] like Figure 8 As shown, the mounting base 32 includes a ring frame 321 and a fixing plate 322. The bottom end of the guide shaft 33 is connected to the ring frame 321. Both ends of the fixing plate 322 are connected to the frame of the ring frame 321. The fixing plate 322 has fixing holes adapted to the dust removal module 10. The dust removal module 10 is located in the hollow area of ​​the ring frame 321 and is fixed through the fixing holes. Specifically, the fixing holes are adapted to the first driving member 11, thereby fixing and limiting the first driving member 11.

[0065] Specifically, there are four guide shafts 33, which are connected to the four corners of the retractable frame 321 respectively.

[0066] like Figure 8 As shown, the moving module 30 also includes a barcode scanner assembly 35, which is tunably connected to the guide shaft 33 for scanning and identifying the motor 70 on the material tray 42 of the dust removal device. Specifically, one end of the barcode scanner assembly 35 is fitted onto a guide shaft 33, allowing it to move up and down along the guide shaft 33 for easy orientation adjustment.

[0067] like Figure 8 As shown, the moving module 30 also includes an ion bar assembly 36. The ion bar assembly 36 is disposed below the mounting base 32 and is used to remove ions from the air. This arrangement reduces electrostatic adsorption of dust particles, preventing tiny particles in the motor 70 from being attracted by ions in the air above and flowing downwards, facilitating centralized collection and preventing them from returning to the motor 70.

[0068] Furthermore, such as Figure 8 As shown, the moving module 30 also includes mounting plates 37. Specifically, there are two mounting plates 37, located on both sides of the dust removal module 10, with each end of the mounting plate 37 fitted onto two guide shafts 33. The mounting plates 37 have multiple mounting holes along their length, allowing for easy installation of other components.

[0069] like Figures 9 to 10 As shown, the dust removal device also includes a working position module 40. The working position module 40 includes a gripper assembly 41, a first fixing member 43, and a second driving member 44. The gripper assembly 41 is located below the dust removal module 10 and is provided with a tray 42 for placing the motor 70. The gripper assembly 41 is movably mounted on the first fixing member 43. The second driving member 44 is disposed at one end of the first fixing member 43 and is drivenly connected to the gripper assembly 41, for driving the gripper assembly 41 to move along the first fixing member 43 so that the motor 70 on the tray 42 is aligned with the dust removal module 10.

[0070] In this embodiment, the second driving component 44 is a lateral movement motor or cylinder.

[0071] In this embodiment, the material tray 42 has multiple placement positions, which can accommodate multiple motors 70. Correspondingly, there are also multiple dust removal modules 10, which can simultaneously remove dust from multiple motors 70 and improve work efficiency.

[0072] like Figures 9 to 10 As shown, the working position module 40 also includes a third driving member 46, which is drivenly connected to the first fixing member 43 and is used to drive the first fixing member 43 to rotate horizontally by a preset angle. Figure 9 Taking the perspective of the middle as an example, the first fixing member 43 is driven to flip inward or outward. Specifically, the third driving member 46 enables the gripper assembly 41 and the material tray 42 to rotate 180°, thereby facilitating loading and unloading.

[0073] In this embodiment, the third driving component 46 is a rotary motor or a cylinder.

[0074] Specifically, the first fixing member is an L-shaped plate, including a horizontal plate and a vertical plate. The gripper assembly 41 is movably disposed on the horizontal plate. The second driving member 44 is located at one end near the vertical plate, and the vertical plate is used for driving connection with the third driving member 46.

[0075] like Figures 9 to 10 As shown, the working module 40 also includes a vibration assembly 47. The vibration assembly 47 is located below the gripper assembly 41 and is used to drive the gripper assembly 41 to vibrate up and down. Specifically, the vibration assembly 47 includes a vibration motor and adjustable eccentric blocks. The adjustable eccentric blocks are installed at both ends of the rotor shaft of the vibration motor, and the excitation force is obtained by utilizing the centrifugal force generated by the high-speed rotation of the rotor shaft and the adjustable eccentric blocks. The vibration assembly 47 can provide vibration along the insertion direction of the dust removal module 10, thereby exciting the motor 70 vertically. During the vibration process, the tiny particles on the motor 70 are internally excited, causing them to detach from the surface of the structural components. Generally, if the tiny particles have static electricity, they may adhere to the surface of the structural components, resulting in a large adhesion force. By using vibration, the tiny particles can be significantly agitated by the airflow.

[0076] It is understandable that if the vibration component 47 vibrates in the horizontal direction, it may cause the vibration component 47 to excite the carrier 71 to vibrate in the XY direction. The carrier 71 may sway left and right, causing interference with the dust removal module 10. This will cause the carrier 71 to collide with the dust removal module and generate tiny particles, which will have a counterproductive effect.

[0077] like Figures 4 to 5 , Figures 9 to 10 As shown, the working station module 40 also includes a dust collection component 48. The dust collection component 48 is located below the first fixing member 43 and corresponds to the gripper component 41. The first fixing member 43 has a hollow area to allow the dust collection component 48 to perform dust collection operations on the motor 70 on the material tray 42. Through this arrangement, the blown-out fine particles can be captured and collected in a timely manner, improving the dust removal effect.

[0078] like Figure 7 and Figure 9As shown, the dust removal device also includes a fourth driving component 50, which is mounted on the frame 20 and drivenly connected to the working position module 40, for driving the working position module 40 to move up and down. This configuration allows for flexible adjustment of the position of the working position module 40 according to usage requirements, providing convenience and speed.

[0079] In this embodiment, the fourth driving component 50 is a vertical moving motor or cylinder.

[0080] like Figures 6 to 7 As shown, the dust removal device also includes a loading / unloading module 60. The loading / unloading module 60 is mounted on the frame 20 and located on one side of the moving module 30, and is used to load and unload the motor 70. In this embodiment, the loading / unloading module 60 is a material box mechanism capable of storing a material tray 42. The motor 70 is stored in the material tray 42, and the material tray 42 is placed within the material box mechanism.

[0081] Specifically, the frame 20 includes a base frame, a vertical beam structure, and a horizontal beam structure. The vertical beam structure is located at one end of the base frame, and one end of the horizontal beam structure is connected to the top of the vertical beam structure, meaning the horizontal beam structure is suspended above the base frame. The top plate 31 is connected and fixed to the horizontal beam structure. The working position module 40 is located in the middle of the base frame, thus placing the moving module 30 above the working position module 40. The fourth drive unit 50 is located on the base frame and on the side closer to the vertical beam structure. The loading / unloading module 60 is located at the end of the base frame away from the vertical beam structure, facilitating loading and unloading.

[0082] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: The dust removal module includes a first driving member 11, a jet head 12, and an air supply mechanism. A jet port 121 is provided on the peripheral sidewall of the jet head 12. The air supply mechanism is connected to the jet head 12 and is used to provide dust removal gas. The first driving member 11 is driven to the jet head 12 and is used to drive the jet head 12 to rotate within the motor 70 to perform dust removal on the motor 70. Thus, during the manufacturing process of the camera module, the interior of the motor 70 of the camera module is subjected to rotary jet dust removal by the jet head 12 extending into it, thereby effectively removing tiny particles inside the motor 70. This prevents tiny particles from affecting the normal operation of the motor 70 or from adhering to the optical path of the camera module, causing a deterioration in the image quality of the camera module, and greatly improves the manufacturing yield of the camera module.

[0083] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
