DETAILED DESCRIPTION

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0040] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0041] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] In order to solve the problem of low manufacturing yield of camera modules in the prior art, the present invention provides a dust removal module and a dust removal device. The dust removal device includes the dust removal module.

[0043] In the prior art, Figures 4 to 5As shown, the motor 70 of the camera module is generally in the form of coil magnet drive, and 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 the power is turned on, the relative force generated by the magnet 73 and the coil can drive the carrier 71 to move. However, the structural form of the moving parts and the fixed parts inside the motor 70 may cause the moving parts to shake when the motor 70 moves, causing the tiny particles originally attached to the surface of the carrier 71 to fall off. The carrier 71 and the base 72 are often formed by injection molding, and for the purpose of strength, the carrier 71 is generally formed by LCP (liquid crystal polymer) material. Since the liquid crystal polymer has a short molecular chain structure, less cross-linking components, and high crystallinity, tiny particles are very likely to appear on the surface. Such tiny particles are easy to fall onto the optical path of the camera module during the power-on movement of the motor 70, thereby affecting the imaging of the camera module, and may also affect the mechanical actuation process of the motor 70, thereby affecting the normal operation of the motor 70.

[0044] For this reason, Figure 1 to Figure 2 As shown, the present application provides a dust removal module for removing dust from the motor 70 of the camera module. The dust removal module includes a first driving member 11, a nozzle 12 and an air supply mechanism. A nozzle 121 is provided on the peripheral side wall of the nozzle 12. The air supply mechanism is connected to the nozzle 12 for providing dust removal gas. The first driving member 11 is drivingly connected to the nozzle 12 for driving the nozzle 12 to rotate in the motor 70 to perform dust removal operation on the motor 70.

[0045] Specifically, Figures 4 to 5 As shown, the carrier 71 has a middle through hole, and the jet port 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 end portion of the jet head 12 extends into the middle through hole of the carrier 71, so that the jet port 121 is located in the motor 70, thereby performing a dust removal operation.

[0046] Through the above-mentioned arrangement, during the manufacturing process of the camera module, the motor 70 of the camera module will be extended with the nozzle 12 therein to perform rotary jet dust removal, thereby effectively removing tiny particles inside the motor 70, thereby preventing the tiny particles from affecting the normal operation of the motor 70 or the tiny particles from being contaminated on the optical path of the camera module and causing the camera quality of the camera module to deteriorate, thereby greatly improving the manufacturing yield of the camera module.

[0047] Since the present application adopts the method of extending into the interior of the motor 70 to spray air, the area of ​​the air jet port 121 relative to the motor 70 cannot be made larger. By adopting the method of rotary jet, it can ensure that the airflow generates a greater impact force inside the motor 70, thereby improving the dust removal effect.

[0048] In this embodiment, there are multiple jet ports 121, and the multiple jet ports 121 are arranged at intervals along the circumference of the jet head 12. Further, the multiple jet ports 121 are arranged at equal intervals along the circumference of the jet head 12. Through the above arrangement, the inside of the motor 70 can be sprayed more evenly and fully, so as to blow out the tiny particles as much as possible and ensure the dust removal effect.

[0049] Furthermore, a plurality of air jets 121 are symmetrically arranged along the central axis of the air jet head 12. Through the above arrangement, when the dust removal module sprays air, the impact force on various positions inside the motor 70 can be increased, and the symmetrical arrangement can make the gas with impact force cause a greater impact force on various places inside the motor 70 when the air jet head 12 rotates, thereby more fully removing dust from the motor 70.

[0050] In this embodiment, there are multiple jet ports 121, and the multiple jet ports 121 are divided into multiple groups along the axial direction of the jet head 12, and the multiple groups of jet ports 121 are arranged at intervals. There are one or more jet ports 121 in each group, and when there are multiple jet ports 121 in each group, the multiple jet ports 121 in each group are arranged at intervals along the circumference of the jet head 12. In other words, the multiple jet ports 121 are arranged in multiple rows up and down. Through the above arrangement, the jet area of ​​the jet head 12 can be increased, causing greater impact force on various places inside the motor 70, thereby having a better dust removal effect.

[0051] Furthermore, the plurality of groups of jet ports 121 are staggered along the circumference of the jet head 12, such as Figure 2 As shown. It can be understood that the above-mentioned staggered arrangement is such that two adjacent groups of jet ports 121 do not overlap but are staggered. Through the above-mentioned arrangement, the degree of dust removal gas impacting the inside of the motor 70 is further improved, so that multiple groups of jet ports 121 can be superimposed to cause greater impact force on the inside of the motor 70, thereby improving the dust removal effect.

[0052] In a specific embodiment, the nozzle head 12 is provided with two groups of nozzles 121, one group of nozzles 121 is multiple, the multiple nozzles 121 are arranged at intervals along the circumference of the nozzle head 12, and the two groups of nozzles 121 are staggered along the circumference of the nozzle head 12. Further, each nozzle 121 extends along the radial direction of the nozzle head 12, that is, it is arranged horizontally. Figure 4 The schematic diagram shows the dust removal module in this case performing dust removal operation on the motor 70. When the nozzle 12 extends into the middle through hole of the carrier 71 and performs rotational jetting, the jetted air flows through the gaps between the internal components of the motor and flows out from the bottom of the motor 70, thereby carrying away tiny particles.

[0053] In another specific embodiment, the arrangement of the air jet 121 is different, for example Figure 3 and Figure 5 As shown, the jet port 121 includes a first jet port 1211 and a second jet port 1212. The first jet port 1211 and the second jet port 1212 are spaced apart along the axial direction of the jet head 12, and the second jet port 1212 is closer to the bottom end of the jet head 12 relative to the first jet port 1211. The second jet port 1212 is tilted upward from the inside to the outside, and the first jet port 1211 extends along the radial direction of the jet head 12.

[0054] That is to say, the first jet port 1211 is set to a horizontal through-type design, so that the first jet port 1211 can spray air in the horizontal direction, and the second jet port 1212 is set to an oblique design, so that the jet of the second jet port 1212 can blow air obliquely upward. Due to the characteristics of the motor structure, in the structural relationship between the moving parts and the stationary parts, there is a risk of direct interference between the outer side of the carrier 71 and the base 72 or the outer shell, so the outer surface of the carrier 71 is a surface with a greater possibility of producing tiny particles, and the inner surface of the carrier 71 is less likely to produce tiny particles because the motor 70 will be assembled into a camera module after the lens is assembled, and after the carrier 71 and the lens are installed, the inner surface of the carrier 71 and the lens will be fixed with glue. Through the above-mentioned setting, since the jet direction of the second jet port 1212 is upward, it can intersect with the jet of the horizontal first jet port 1211, so that the total gas between the second jet port 1212 and the first jet port 1211 is Figure 5 The dust flows in the manner shown, flowing from top to bottom and fully into the outer surface of the carrier 71 and other positions, thereby greatly improving the dust removal efficiency.

[0055] Further, there are a plurality of first jet ports 1211 , which are spaced apart along the circumference of the jet head 12 . Correspondingly, there are also a plurality of second jet ports 1212 , which are spaced apart along the circumference of 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 with components of other modules. The upper joint 14 is connected to the rotary joint 13 and the first driving member 11 respectively, and the lower joint 15 is connected to the first driving member 11 and the nozzle 12 respectively. The clamping block 16 is located between the upper joint 14 and the first driving member 11, and is used to tightly connect the first driving member 11.

[0057] In this embodiment, the air pipe of the air supply mechanism can be connected to the rotary joint 13, and 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, and the bottom end of the air supply channel is connected to the nozzle 12, or the air pipe of the air supply mechanism passes 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 in sequence, thereby connecting to the nozzle 12.

[0058] Furthermore, the first driving member 11 may be integrated with an air supply mechanism to provide air pressure for the spray head 12 .

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

[0060] like Figure 6 to Figure 7 As shown, the present application also provides a dust removal device, including a frame 20, the dust removal module 10 and a moving module 30. The dust removal module 10 is arranged in a one-to-one correspondence with the motor 70. The moving module 30 is arranged to be adjustable in the up and down position relative to the frame 20, and the dust removal module 10 is arranged on the moving module 30 to follow the up and down movement of the moving module 30 and extend into the motor 70 or withdraw from the motor 70.

[0061] like Figure 8 and Fig.10 As shown, the moving module 30 includes a top plate 31, a fixing seat 32 and a guide shaft 33. The top plate 31 is connected and fixed to the frame 20. The dust removal module 10 is arranged on the fixing seat 32. The bottom end of the guide shaft 33 is connected to the fixing seat 32, and the top plate 31 is provided with a shaft fixing support 34, and the top end of the guide shaft 33 is penetrated by the shaft fixing support 34, and the shaft fixing support 34 is used to lock the guide shaft 33 after the guide shaft 33 moves a preset distance.

[0062] Specifically, the shaft fixing support 34 includes a seat body and a locking piece. The seat body is embedded in the top plate 31 and is provided with a vertical through hole and a horizontal locking hole. The guide shaft 33 is passed through the vertical through hole. The locking piece 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 , and the multiple guide shafts 33 are arranged at intervals along the circumference of the fixing seat 32 .

[0064] like Figure 8 As shown, the fixing seat 32 includes a circular frame 321 and a fixing plate 322. The bottom end of the guide shaft 33 is connected to the circular frame 321. Both ends of the fixing plate 322 are connected to the frame of the circular frame 321. The fixing plate 322 is provided with a fixing hole adapted to the dust removal module 10. The dust removal module 10 is located in the hollow area of ​​the circular frame 321 and is fixed to the fixing hole. Specifically, the fixing hole is adapted to the first driving member 11, so as to fix the first driving member 11 in a limited position.

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

[0066] like Figure 8 As shown, the mobile module 30 also includes a barcode scanner component 35, which is adjustably connected to the guide shaft 33 and is used to scan the code to identify the motor 70 on the material tray 42 of the dust removal device. Specifically, one end of the barcode scanner component 35 is sleeved on a guide shaft 33, so that it can move up and down along the guide shaft 33, which is convenient for adjusting the orientation.

[0067] like Figure 8 As shown, the mobile module 30 also includes an ion rod assembly 36. The ion rod assembly 36 is arranged below the fixed base 32 and is used to remove ions in the air. Through the above arrangement, it is possible to reduce electrostatic adsorption of dust particles, so that the tiny particles in the motor 70 will not be attracted by the ions in the air above and flow downward, which is convenient for centralized collection and avoids returning to the motor 70 again.

[0068] Further, such as Figure 8 As shown, the mobile module 30 also includes a mounting plate 37. Specifically, there are two mounting plates 37, which are respectively located on both sides of the dust removal module 10, and the two ends of each mounting plate 37 are respectively sleeved on the two guide shafts 33. Among them, the mounting plate 37 is provided with a plurality of mounting holes in the length direction, so that the mounting plate 37 can be conveniently installed with other devices.

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

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

[0071] In this embodiment, the material tray 42 has multiple placement positions, so that multiple motors 70 can be placed. Correspondingly, there are also multiple dust removal modules 10, so that dust can be removed from multiple motors 70 at the same time, thereby improving work efficiency.

[0072] like Figures 9 and 10 As shown, the working position module 40 further includes a third driving member 46, which is drivingly connected to the first fixing member 43 and is used to drive the first fixing member 43 to rotate horizontally by a preset angle. Fig. 9 For example, the first fixing member 43 is driven to flip inward or outward. Specifically, the third driving member 46 can rotate the clamping jaw assembly 41 and the material tray 42 by 180 degrees, so as to facilitate loading and unloading.

[0073] In this embodiment, the third driving member 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 clamping jaw assembly 41 is movably arranged on the horizontal plate. The second driving member 44 is located at one end close to the vertical plate, and the vertical plate is used for driving connection with the third driving member 46.

[0075] like Figures 9 and 10 As shown, the working position module 40 also includes a vibration component 47. The vibration component 47 is arranged below the clamping jaw component 41, and is used to drive the clamping jaw component 41 to vibrate up and down. Specifically, the vibration component 47 includes a vibration motor and an adjustable eccentric block, and the adjustable eccentric block is installed at both ends of the rotor shaft of the vibration motor, and the centrifugal force generated by the high-speed rotation of the rotor shaft and the adjustable eccentric block is used to obtain the exciting force. The vibration component 47 can provide vibration along the extension direction of the dust removal module 10, thereby exciting the motor 70 in the vertical direction, so that the tiny particles on the motor 70 will be internally excited during the vibration process, and the tiny particles can fall off the surface of the structural member. Generally speaking, if there is static electricity in the tiny particles, it may cause the tiny particles to be adsorbed on the surface of the structural member, which will make the adsorption force between the tiny particles and the surface of the structural member larger. By using vibration, the tiny particles can be greatly blown by the airflow.

[0076] It is understandable that if the vibration component 47 vibrates in the horizontal direction, the vibration component 47 may excite the carrier 71 to vibrate in the XY direction, and the carrier 71 may swing left and right to interfere with the dust removal module 10, thereby causing the carrier 71 to collide with the dust removal module to produce tiny particles, which has a counter-effect.

[0077] like Figures 4 to 5 , Figures 9 and 10 As shown, the working position module 40 also includes a dust collecting assembly 48. The dust collecting assembly 48 is located below the first fixing member 43 and is arranged corresponding to the clamping claw assembly 41. The first fixing member 43 has a hollow area so that the dust collecting assembly 48 can perform dust collecting operation on the motor 70 on the material tray 42. Through the above arrangement, the blown-out tiny particles can be captured and collected in time to improve the dust removal effect.

[0078] like Figure 7 and Fig. 9As shown, the dust removal device also includes a fourth driving member 50, which is arranged on the frame 20 and is drivingly connected to the working position module 40, and is used to drive the working position module 40 to move up and down. Through the above arrangement, the position of the working position module 40 can be flexibly adjusted according to the use requirements, which is convenient and fast.

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

[0080] like Figure 6 to Figure 7 As shown, the dust removal device further includes a loading and unloading module 60. The loading and unloading module 60 is disposed on the frame 20 and located on one side of the moving module 30, and is used to perform loading and unloading operations on the motor 70. In this embodiment, the loading and 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 in the material box mechanism.

[0081] Specifically, the frame 20 includes a base frame, a vertical beam structure and a cross beam structure. The vertical beam structure is arranged at one end of the base frame, and one end of the cross beam structure is connected to the top of the vertical beam structure, that is, the cross beam structure is suspended above the base frame, and the top plate 31 is connected and fixed to the cross beam structure.
