Description

Technical Field

[0002] Compact camera modules are commonly used electronic components in terminal electronic products such as mobile phones and computers. Due to their small size, it is difficult to continuously improve the manufacturing yield of compact camera modules. As an important component of the camera module, the assembly and manufacturing yield of the motor will affect the overall manufacturing yield of the camera module.

[0003] In a variable aperture camera module, it is necessary to install an FPC-Coil (flexible printed circuit board with a coil) into the card slots on both sides of the stator. There are coils and Hall elements on the FPC. After the FPC is powered on, the current drives the mover of the variable aperture, thereby controlling the contraction of the variable aperture blades. However, the above-mentioned circuit board is generally a special-shaped circuit board, and it is necessary to bend the circuit board to fit the structural components for installation. However, in the context of the miniaturization of current camera modules, the structural gap reserved between the circuit board and the card slot is small. Therefore, it is difficult to bend such a special-shaped circuit board to the card slot on the side of the stator during assembly. The existing bending devices cannot accurately and efficiently bend the circuit board, making it difficult to ensure the manufacturing yield of the motor, and further affecting the manufacturing yield of the camera module.

[0057] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0058] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0059] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contours of the components themselves, but the above orientation terms are not used to limit the present invention.

[0060] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] To solve the problem of low manufacturing yield of camera modules in the prior art, the present invention provides a bending device.

[0062] As Figures 1 to 2 shown, the camera module motor 100 includes a circuit board 101 and a stator 102. The circuit board 101 is sleeved on the stator 102, and both sides of the circuit board 101 are respectively provided with coils, and Hall elements are provided on the coils. Correspondingly, both sides of the stator 102 are provided with card slots 1021, and the coils and Hall elements on both sides of the circuit board 101 need to be bent to be installed into the card slots 1021. That is to say, the coils and the Hall elements thereon are the parts to be bent 1011.

[0063] As Figure 3 、 Figures 11 to 14 shown, the bending device is used to bend the circuit board 101 of the camera module motor 100, and includes a workbench 10, a first bending assembly 20, a limiting assembly 30 and a second bending assembly 40. The workbench 10 is used to place the camera module motor 100. The first bending assembly 20 includes a first bending part 21, and the first bending part 21 is located on the side of the workbench 10 and is arranged to be liftable, and is used to drive the part to be bent 1011 of the circuit board 101 to bend upward by a first preset angle. The limiting assembly 30 is located above the workbench 10 and is arranged to be liftable, and is used to limit and fix the camera module motor 100 after the part to be bent 1011 is bent by the first preset angle. The second bending assembly 40 includes a second bending part 41, and the second bending part 41 is located on the side of the workbench 10 and is arranged to be horizontally movable, and is used to drive the part to be bent 1011 to continue to bend inward by a second preset angle.

[0064] By setting two bending assemblies to perform step-by-step bending on the circuit board 101, the bending of the circuit board 101 is more sufficient, and when the originally flat circuit board 101 is bent to the preset angle, it will not cause the bending failure of the circuit board 101 due to unexpected bending, ensuring the effective bending of the circuit board 101. Further, by setting the limiting assembly 30 to limit and fix the camera module motor 100, it is avoided that the circuit board is deformed during the operation of the second bending assembly, thereby improving the manufacturing yield of the camera module motor, and further ensuring the manufacturing yield of the camera module.

[0065] It should be noted that Figure 1 and Figure 2Shows three position states of the portion 1011 to be bent. Among them, the portion 1011 to be bent in the horizontal state is the initial unbent state; the portion 1011 to be bent in the inclined state is the state after being bent by the first bending assembly 20. At this time, the included angle between the portion 1011 to be bent and the horizontal plane is the first preset angle; the portion 1011 to be bent in the vertical or substantially vertical state is the state after being bent by the second bending assembly 40. At this time, the portion 1011 to be bent is installed in the card slot 1021.

[0066] In this embodiment, the sum of the first preset angle and the second preset angle is 90°. That is, the portion 1011 to be bent after two bends is in the vertical state. Specifically, the range of the first preset angle is 70° to 80°. Correspondingly, the range of the second preset angle is 10° to 20°. It can be understood that the two bends can be divided into rough adjustment and fine adjustment. Therefore, the first preset angle needs to be a larger angle to complete most of the stroke, and the second preset angle is a smaller angle to complete the final fine adjustment stroke.

[0067] In this embodiment, the movement direction of the second bending assembly 40 is defined as the X-axis direction, and the length direction of the workbench 10 is the Y-axis direction, as Figure 11 shown. Correspondingly, the up and down direction is the Z-axis direction.

[0068] In this embodiment, as Figures 11 to 13 、 Figure 15 shown, there are two first bending assemblies 20. The two first bending assemblies 20 are symmetrically arranged with respect to the workbench 10, so as to bend the portions 1011 to be bent on both sides of the circuit board 101 respectively.

[0069] Specifically, as Figure 14 and Figure 16 shown, the first bending portion 21 includes a first main body portion and a first bending head 211. Among them, the first main body portion is a plate-like structure arranged vertically, and the first bending head 211 extends from the top of the first main body portion toward the direction close to the workbench 10. One side of the first bending head 211 close to the workbench 10 has a first avoidance notch 212 for avoiding the workbench 10. Further, one side of the first bending head 211 close to the workbench 10 has a contact inclined surface 213, and the contact inclined surface 213 is in contact with the portion 1011 to be bent. It can be understood that the inclination angle of the contact inclined surface 213 is equal to the first preset angle.

[0070] As Figures 22 to 24 shown, avoidance grooves 16 are provided on both sides of the workbench 10. The portion 1011 to be bent is located at the avoidance groove 16 in the initial state, and the first bending head 211 moves up and down along the avoidance groove 16 to bend the portion 1011 to be bent upward.

[0071] Further, as Figures 11 to 13 shown, the first bending assembly 20 further includes a first driving mechanism 22. The first driving mechanism 22 is drivingly connected to the first bending portion 21 for driving the first bending portion 21 to move. Specifically, the first driving mechanism 22 includes a first driving member 221 and a first connecting plate 222. The first connecting plate 222 is connected to the first bending portion 21, and the first driving member 221 is drivingly connected to the first connecting plate 222, thereby driving the first connecting plate 222 and then driving the first bending portion 21 to move up and down. In this embodiment, for reasonable layout, the first driving mechanism 22 is placed on one side of the second bending assembly 40, that is, arranged side by side with the second bending assembly 40. In this case, the first connecting plate 222 is placed along the Y-axis direction. Further, in order to enable the first bending portion 21 to completely separate from the workbench 10 and avoid interference, the first driving mechanism 22 further includes a second driving member 223 and a bottom plate. The first driving mechanism 22 is arranged on the bottom plate, and the second driving member 223 is drivingly connected to the bottom plate, thereby driving the whole of the first driving mechanism 22, the first connecting plate 222 and the first bending portion 21 to move along the X-axis direction.

[0072] During the working process of the first bending assembly 20, the first bending portion 21 is initially located outside the range of the workbench 10. The second driving member 223 first drives the first bending portion 21 to approach the workbench 10 along the X-axis direction and makes the first bending portion 21 correspond to the avoidance groove 16. Then the first driving member 221 drives the first bending portion 21 to move upward along the avoidance groove 16 to a preset height. When continuing to move upward after coming out of the avoidance groove 16, the contact inclined surface 213 of the first bending head 211 starts to contact the portion to be bent 1011 and pushes the portion to be bent 1011 to bend upward until it is bent to a first preset angle, as Figure 17 shown.

[0073] In this embodiment, the limiting assembly 30 has a first floating stroke in the height direction to perform flexible limiting and fixing on the camera module motor 100. Specifically, as Figures 4 to 7 shown, the limiting assembly 30 includes a lifting mechanism 31, a first fixing member 32, a first floating member 33 and a first elastic member 34. The lifting mechanism 31 is drivingly connected to the first fixing member 32. The first floating member 33 is located below the first fixing member 32 and is vertically and floatingly connected to the first fixing member 32. The lower end surface of the first floating member 33 is the limiting end surface. The two ends of the first elastic member 34 are respectively connected to the first fixing member 32 and the first floating member 33. The first elastic member 34 provides an elastic supporting force to the first floating member 33 to enable the first floating member 33 to have a first floating stroke.

[0074] Further, as Figure 4As shown in the figure, the lifting mechanism 31 includes a support frame 311, a third driving member 312, and a cover plate 313. Among them, the support frame 311 is located on the side of the workbench 10 in the Y-axis direction. The support frame 311 has a vertically arranged guide rail. The third driving member 312 is movably connected to the guide rail. The cover plate 313 is arranged on the third driving member 312 and is located above the workbench 10. The cover plate 313 is used to be fixedly connected to the first fixing member 32, so as to drive the first fixing member 32 and the first floating member 33 to move up and down.

[0075] Furthermore, as shown in Figures 5 to 7 , Figure 9 the figure, the limiting component 30 further includes a connecting member 39. The first floating member 33 is provided with a through hole 335, and the first fixing member 32 is provided with a mounting hole 321. The connecting member 39 passes through the through hole 335 and extends into the mounting hole 321 to be connected to the first fixing member 32. A limiting step for limiting and stopping the connecting member 39 is provided in the through hole 335, and the connecting member 39 has a movable section in the through hole 335.

[0076] Specifically, the connecting member 39 can be a screw, the mounting hole 321 is a threaded hole, and the length of the connecting member 39 is greater than the height difference between the through hole 335 and the mounting hole 321. If the first floating member 33 and the first fixing member 32 are closely attached up and down, after the connecting member 39 passes through the through hole 335 and is threadedly connected to the mounting hole 321, the nut of the connecting member 39 will not abut against the limiting step in the through hole 335, but there is a certain height difference. It can be understood that if there is no first elastic member 34 and no external force is applied to the first floating member 33, under the action of gravity, the nut of the connecting member 39 will abut against the limiting step in the through hole 335. Under the elastic supporting force of the first elastic member 34, the connecting member 39 can have a movable section of a certain length in the through hole 335 without abutting against the limiting step in the through hole 335, so that the first floating member 33 is in a floating state.

[0077] In this embodiment, under the connection action of the connecting member 39 and the elastic supporting force of the first elastic member 34, the first floating member 33 can have a floating stroke along the height direction, and the first floating member 33 can be supported by the elastic force of the first elastic member 34, so that the first elastic member 34 can return to the equilibrium position. When the cover plate 313 is pressed down, the circuit board 101 of the camera module motor 100 can be flexibly pressed with this floating stroke, so as to prevent the circuit board 101 from being damaged due to the hard interference of the cover plate 313.

[0078] In this embodiment, the size of the connecting member 39 is adapted to the through hole 335, so as to play a vertical guiding role and restrict the first floating member 33 and the first fixing member 32 to have a relatively collinear floating stroke.

[0079] In this embodiment, receiving holes are formed in the lower end surface of the first fixing member 32 and the upper end surface of the first floating member 33, and both ends of the first elastic member 34 are respectively received in the receiving holes to improve the connection stability of the first elastic member 34.

[0080] As Figures 5 to 7 , Figures 9 to 10 and Figures 22 to 24 shown, a positioning pin 334 is provided on the lower end surface of the first floating member 33, and a positioning hole 11 adapted to the positioning pin 334 is formed in the workbench 10. When the positioning pin 334 descends, it extends into the positioning hole 11. Through the above settings, the first floating member 33 can be accurately aligned with the workbench 10, so as to accurately limit and fix the camera module motor 100.

[0081] As Figures 5 to 7 , Figures 9 to 10 shown, a middle concave portion 331 for avoiding the first bent portion 21 is formed on the lower end surface of the first floating member 33. A limiting portion 336 is provided on the middle concave portion 331, and the limiting portion 336 is used to limit and fix the camera module motor 100. It can be understood that since the camera module motor 100 also has a certain height, the middle concave portion 331 is also for avoiding the camera module motor 100. When the limiting component 30 limits and fixes the camera module motor 100, the portions at both ends of the middle concave portion 331 of the first floating member 33 are in contact with the workbench 10, and the middle concave portion 331 is the position for limiting and fixing the camera module motor 100.

[0082] Generally, a magnetic attraction material is injection-molded inside the camera module motor 100. Specifically, the magnetic attraction material can be a paramagnetic material, such as iron-nickel and other materials. Therefore, the limiting component 30 can be provided with a magnetic attraction component to magnetically attract and fix the camera module motor 100, so as to achieve a better limiting and fixing effect on the camera module motor 100.

[0083] In this embodiment, as Figure 5 , Figures 7 to 10 shown, the limiting component 30 further includes a magnetic attraction member 35. A first receiving groove 332 is formed on the upper end surface of the first floating member 33. The first receiving groove 332 is communicated with the middle concave portion 331. At least a part of the magnetic attraction member 35 is received in the first receiving groove 332 and is used to magnetically attract and fix the camera module motor 100. Through the above settings, the magnetic attraction member 35 can achieve an in-buried design to reduce possible problems of collision interference. Specifically, the first receiving groove 332 is correspondingly arranged with respect to the camera module motor 100.

[0084] In this embodiment, the magnetic attraction member 35 can be a permanent magnet or an electromagnet.

[0085] In this embodiment, in order to abut against the camera module motor 100 more evenly, there are multiple limiting portions 336. The multiple limiting portions 336 are divided into multiple groups in pairs, and the two limiting portions 336 of each group are respectively located on both sides of the first accommodating groove 332, and the multiple groups of limiting portions 336 are symmetrically arranged in the middle concave portion 331. Further, on each side of the first accommodating groove 332, the multiple limiting portions 336 are symmetrically arranged with respect to the avoidance groove 16 or rather the first bending portion 21.

[0086] In this embodiment, there are multiple first elastic members 34, and the multiple first elastic members 34 are symmetrically arranged along the Y-axis direction with respect to the center of the first floating member 33. It can be understood that the first elastic members 34 are also symmetrically arranged with respect to the limiting portions 336, so as to make the limiting portions 336 the points of central moment balance as much as possible. The limiting end faces are supported by the symmetrically arranged first elastic members 34 to be relatively flat, so that the limiting effect of the limiting portions 336 can be better. It should be noted that the length direction of the first floating member 33 is also the Y-axis direction.

[0087] Further, there are also multiple connecting members 39, and the multiple connecting members 39 are symmetrically arranged along the Y-axis direction with respect to the center of the first floating member 33. Through the above settings, the uniform connection between the first fixing member 32 and the first floating member 33 can be realized, and the limiting end face can be made as flat as possible. Still further, the connecting members 39 and the first elastic members 34 are arranged in an alternating manner along the Y-axis direction, so that the connection and supporting effects of the two are more uniform, and the flatness of the limiting end face is further ensured.

[0088] Further, as Figures 7 to 9 、 Figure 17 shown, a second accommodating groove 333 is formed in the middle concave portion 331, and the first accommodating groove 332 is communicated with the second accommodating groove 333. That is to say, the first accommodating groove 332, the second accommodating groove 333 and the middle concave portion 331 are communicated with each other in sequence from top to bottom. A buffer member 36 is arranged at the bottom of the magnetic attraction member 35, and at least a part of the buffer member 36 is accommodated in the second accommodating groove 333 and the bottom end protrudes downward from the surface of the middle concave portion 331. That is to say, the lower end face of the buffer member 36 is lower than the surface of the middle concave portion 331, so that when the first floating member 33 is attached to the workbench 10, the buffer member 36 first contacts the camera module motor 100 to better support the camera module motor 100 and prevent the camera module motor 100 from being damaged.

[0089] In this embodiment, the deformation amount of the buffer member 36 is greater than the gap difference between the surface of the middle concave portion 331 and the lower end face of the buffer member 36. Through the above settings, the buffer member 36 can have sufficient deformation space to provide sufficient abutting space.

[0090] Further, there are two buffer members 36, and the two buffer members 36 are located at both ends of the bottom of the magnetic attraction member 35, so as to improve the contact uniformity and stability with the camera module motor 100.

[0091] In this embodiment, the buffer member 36 is made of silica gel. Of course, the buffer member 36 can also be other flexible materials such as rubber, which can be selected according to actual needs.

[0092] As Figures 6 to 8 shown, the limiting component 30 further includes a first force measuring module 37. The first force measuring module 37 is arranged between the first fixing member 32 and the first floating member 33 and is used to measure the force received by the first floating member 33.

[0093] In this embodiment, in order to make reasonable use of space, the first force measuring module 37 is arranged above the magnetic attraction member 35. As Figures 7 to 8 shown, the limiting component 30 further includes a second elastic member 38. The two ends of the second elastic member 38 are respectively connected to the first force measuring module 37 and the magnetic attraction member 35, so as to provide an elastic supporting force for the magnetic attraction member 35, so that the magnetic attraction member 35 limits and fixes the camera module motor 100 downward.

[0094] Specifically, a receiving recess is formed at the middle position of the lower end surface of the first fixing member 32. The first force measuring module 37 includes a fixed end and a measuring element. Among them, the fixed end is located in the receiving recess and is fixedly connected to the first fixing member 32, and the measuring element is connected to the second elastic member 38. Specifically, the measuring element and the magnetic attraction member 35 respectively have receiving holes, and the two ends of the second elastic member 38 are respectively received in the two receiving holes.

[0095] In this embodiment, both the first elastic member 34 and the second elastic member 38 are springs.

[0096] During the floating and pressing down process of the first floating member 33, although the first elastic member 34 will undergo a certain amount of collapse, if it exceeds the elastic deformation section of the first elastic member 34 during the collapse stage, it may cause damage to the first elastic member 34. Or, after the first floating member 33 is actually interfered by an object, although a certain floating pressing process is carried out via the first elastic member 34, if it continues to press down after the floating pressing process, it may cause an accident. Therefore, in this embodiment, the first force measuring module 37 is set to measure the force received by the first floating member 33 during the pressing down process. Specifically, the first force measuring module 37 is connected to the first fixing member 32 via a controller. The measured value of the first force measuring module 37 is read by the controller, and the controller is set with a pre-pressure value, and the maximum value of this pre-pressure value is controlled to be the maximum elastic force section before the collapse of the first elastic member 34. For example, if the elastic collapse section of the first elastic member 34 is 10 mm, then the maximum value of this pre-pressure value is 0.25 (kgf / mm) * 10 mm, thereby preventing the first floating member 33 from exceeding the elastic deformation section.

[0097] Of course, the floating travel of the limiting component 30 driven downward from the initial position is greater than the maximum elastic force section before the collapse of the first elastic member 34, so as to enable the limiting component 30 to drive the first fixing member 32 and the first floating member 33 to move downward, and to realize the process from non-contact to elastic contact, so as to better pre-press the camera module motor 100.

[0098] In this embodiment, as Figures 11 to 13 shown, there are two second bending components 40, and the two second bending components 40 are symmetrically arranged with respect to the workbench 10, so as to respectively perform bending processing on the to-be-bent parts 1011 on both sides of the circuit board 101.

[0099] In this embodiment, the second bending component 40 has a second floating travel in the horizontal direction, so that the second bending component 40 can perform flexible bending on the to-be-bent part 1011. Specifically, as Figures 11 to 13 shown, the second bending component 40 further includes a second driving mechanism 42, a second fixing member 43, a second floating member 44, and a third elastic member 45. The second driving mechanism 42 is drivingly connected to the second fixing member 43. The second floating member 44 is located on the side of the second fixing member 43 close to the workbench 10 and is horizontally movably connected to the second fixing member 43. The second bending part 41 is connected to one end of the second floating member 44 close to the workbench 10. Both ends of the third elastic member 45 are respectively connected to the second fixing member 43 and the second floating member 44, and the third elastic member 45 provides an elastic pre-tightening force to the second floating member 44, so that the second floating member 44 has a second floating travel.

[0100] In this embodiment, the third elastic member 45 is a spring.

[0101] It can be understood that, similar to the floating principle of the limit component 30, the second fixing member 43 and the second floating member 44 are also supported by a spring. When the second bending portion 41 contacts the circuit board 101, due to the elastic support of the third elastic member 45, the second floating member 44 has a floating preloading effect on the circuit board 101.

[0102] In this embodiment, as Figure 18 shown, the first bending portion 21 of the first bending assembly 20 first pushes the portion to be bent 1011 upward for the first bending, and then the first floating member 33 of the limit component 30 can achieve the supporting effect on the upper end surface of the camera module motor 100. Furthermore, the second bending portion 41 of the second bending assembly 40 horizontally pushes the portion to be bent 1011 inward for the second bending, and the second floating member 44 can provide the supporting effect on the side surface of the circuit board 101, so as to simultaneously achieve the floating preloading effect on the upper end surface and the side surface of the circuit board 101, making the limiting and fixing effect on the circuit board 101 better, and preventing the circuit board 101 from deforming in other directions due to excessive degrees of freedom of the circuit board 101 caused by pressing the surface of the circuit board 101 unilaterally, such as pressing the side surface of the circuit board 101 or pressing the upper end surface of the circuit board 101 unilaterally.

[0103] In this embodiment, as Figure 14 shown, there are two second bending portions 41, and the two second bending portions 41 are symmetrically arranged on both sides of the first bending portion 21. Specifically, the second bending portion 41 includes a second main body portion and a second bending head 411, and the second bending head 411 is arranged on the side of the second main body portion close to the workbench 10. Limiting recesses are formed on the sides of the two second bending heads 411 close to each other, corresponding to both ends of the portion to be bent 1011 respectively. When the second bending head 411 contacts the portion to be bent 1011, both ends of the portion to be bent 1011 respectively extend into the two limiting recesses, so as to ensure that the portion to be bent 1011 does not shift during the bending process.

[0104] In this embodiment, as Figure 19 shown, the second driving mechanism 42 includes a fourth driving member 421 and a second connecting plate 422. The fourth driving member 421 is drivingly connected to the second connecting plate 422, so as to drive the second connecting plate 422 to move along the X-axis direction.

[0105] As Figures 11 to 13 、 Figure 19 shown, an elastic force adjusting member 46 is arranged on the second fixing member 43. The elastic force adjusting member 46 is connected to one end of the third elastic member 45 and is horizontally movably arranged, and is used for adjusting the magnitude of the elastic pre-tightening force.

[0106] Specifically, as Figure 19As shown, the second fixing member 43 includes a third connecting plate 431. The elastic force adjusting member 46 is disposed on the side of the third connecting plate 431 away from the second floating member 44. A slide rail in the X-axis direction is provided on the side of the third connecting plate 431 close to the workbench 10, and the second floating member 44 is movably connected to the slide rail.

[0107] Further, as Figure 19 shown, the second bending assembly 40 further includes a second force measuring module 48. The second force measuring module 48 is disposed on the third connecting plate 431 and located between the elastic force adjusting member 46 and the second floating member 44, and is used to measure the force received by the second floating member 44. One end of the third elastic member 45 is connected to the second force measuring module 48. That is to say, the third elastic member 45 is connected to the elastic force adjusting member 46 through the second force measuring module 48.

[0108] In this embodiment, the elastic force adjusting member 46 is a knob structure. The knob structure can adopt the structure of a gear and a rack, and can convert the rotational motion into a linear motion. Of course, other structural forms such as a cam push rod, a crank rocker, a worm and a worm wheel, and a lead screw nut can also be adopted. By extending or contracting the abutting head at one end of the elastic force adjusting member 46, the elastic pre-tightening force of the third elastic member 45 is controlled.

[0109] Further, as Figure 19 shown, the second fixing member 43 further includes a Y-axis displacement mechanism 432 and a Y-axis adjusting member 433. The Y-axis displacement mechanism 432 is disposed on the second connecting plate 422, and the third connecting plate 431 is movably connected to the Y-axis displacement mechanism 432, so as to be able to move along the Y-axis relative to the second connecting plate 422. The Y-axis adjusting member 433 can also be a knob structure, so as to control the Y-axis displacement length of the third connecting plate 431.

[0110] Further, the second fixing member 43 further includes a limiting member 434. The limiting member 434 is disposed on the side of the third connecting plate 431 close to the workbench 10. A limiting groove is correspondingly formed on the outer side of the second floating member 44 in the X-axis direction, and the limiting member 434 extends into the limiting groove, so as to limit the second floating member 44 left and right in the X-axis direction. Through the above settings, the second floating member 44 is prevented from being pushed out of the slide rail by the third elastic member 45 and the third elastic member 45 has a preset elastic pre-tightening force.

[0111] In this embodiment, corresponding to the two second bending portions 41, the second floating members 44, the third elastic members 45, the elastic force adjusting members 46 and the limiting members 434 are also both two, and the above two components are arranged at intervals along the Y-axis direction.

[0112] In this embodiment, the connection point of the third elastic member 45 and the second floating member 44 deviates from the central axis of the second floating member 44 along the moving direction. That is to say, the connection point of the third elastic member 45 and the second floating member 44 deviates from the central axis of the second floating member 44 along the X-axis direction. Correspondingly, the elastic force adjusting member 46 also deviates from the central axis of the second floating member 44 along the X-axis direction.

[0113] That is to say, the elastic force adjusting member 46 and the third elastic member 45 in this embodiment are asymmetrically arranged with respect to the second floating member 44. Therefore, the elastic pre-tightening forces provided by the second floating member 44 and the third elastic member 45 to the second floating member 44 are asymmetric. By applying different elastic pre-tightening forces to the second floating member 44, under the influence of torque, the position of the second floating member 44 can be affected, and further the position of the second bending portion 41 can be affected, especially along the arc of the contact point between the third elastic member 45 and the second floating member 44. Thus, the position state of the second bending portion 41 can be adjusted, so as to better adapt to the situation of limiting the camera module motor 100.

[0114] In this embodiment, after the circuit board 101 is bent, it needs to be internally attached to the base, and no external exposed part of the circuit board 101 is allowed. The external exposed part may cause interference with other structural parts of the camera module or cause interference problems in the assembly of the camera module. The tightness of the bending and attachment of the circuit board 101 can be changed by adjusting the elastic pre-tightening force provided by the elastic force adjusting member 46 to the second floating member 44. Under the influence of torque, the position state of the second bending portion 41 can ultimately be affected, so that it can be conveniently adjusted according to the type of the camera module motor 100.

[0115] Specifically, because the flatness of the plates of different circuit boards 101 is inconsistent, local micro-settings need to be performed, and micro-adjustments are made according to the actual size after bending. The bent camera module motor 100 is photographed to confirm the gap between the circuit board 101 after bending and the stator 102. After the camera module motor 100 is placed flat, it is photographed from top to bottom for measurement. When there is a gap, adjustment is required.

[0116] In addition, since both sides of the workbench 10 in this embodiment are provided with the second bending assemblies 40, the position state of the second bending portion 41 can be adjusted more comprehensively.

[0117] As Figure 20 shown, the second bending assembly 40 further includes a heating assembly 47. The heating assembly 47 is disposed in the second bending portion 41 and is used to heat the portion 1011 to be bent. Specifically, when the second bending portion 41 completes the secondary bending of the circuit board 101, the heating assembly 47 starts to work to heat and cure the circuit board 101.

[0118] Furthermore, as Figure 20As shown by the dashed line in the figure, the heating assembly 47 includes a heating element 471 and a temperature measuring element 472. The heating element 471 is located on one side of the second bending portion 41 close to the second bending head 411. The temperature measuring element 472 is used to measure the heating temperature of the heating element 471, so as to judge whether the heating temperature exceeds the standard value during the hot pressing process. By setting the embedded heating assembly 47, the circuit board 101 becomes relatively flexible and will not return to its original state after being bent and cooled to room temperature, thereby improving the yield of the hot pressing of the circuit board 101. In this embodiment, the heating element 471 can be an electric heating element, and the temperature measuring element 472 can be a thermocouple sensor.

[0119] Further, as Figure 19 shown, the second bending assembly 40 further includes a heat insulation plate 49. The second bending portion 41 and the second floating member 44 are connected through the heat insulation plate 49, so as to play a role in heat insulation and heat preservation and improve the heating efficiency of the heating assembly 47.

[0120] In this embodiment, the workbench 10 has a positioning structure adapted to the shape of the camera module motor 100, such as a positioning groove and / or a positioning rib, etc., so as to position and fix the camera module motor 100 on the workbench 10.

[0121] As Figures 11 to 13 、 Figures 22 to 24 shown, the bending device further includes a suction assembly 50. The workbench 10 is provided with a suction hole 12 and an internal suction flow channel 13 communicated with the suction hole 12. The suction hole 12 is correspondingly arranged with the camera module motor 100. The suction assembly 50 is communicated with the internal suction flow channel 13 and is used to perform a suction operation to adsorb and fix the camera module motor 100.

[0122] Specifically, as Figure 21 shown, the suction assembly 50 includes a suction joint 51 and a suction member. The suction joint 51 is arranged at one end of the workbench 10 and is communicated with the internal suction flow channel 13. The suction member is communicated with the suction joint 51 through an air pipe, so as to perform a suction operation to adsorb and fix the camera module motor 100.

[0123] In this embodiment, the suction hole 12 is vertically arranged, and the internal suction flow channel 13 is horizontally arranged. That is to say, the suction air path is a path that first goes downward and then outward. By adopting the above air path arrangement, the suction hole 12 can be set to be multiple, so as to improve the adsorption and fixing effect.

[0124] Further, as Figures 11 to 13 、 Figure 21As shown, the bending device further includes a base 60, a third driving mechanism 70, and an air suction control component 80. The workbench 10 is arranged on the top of the base 60. The workbench 10 is provided with a third accommodation groove 14 penetrating up and down, and the third accommodation groove 14 communicates with the air suction hole 12. The air suction control component 80 is arranged on the base 60 and at least a part of it extends into the third accommodation groove 14. The third driving mechanism 70 is drivingly connected to the air suction control component 80. The third driving mechanism 70 drives the air suction control component 80 to move relative to the workbench 10, so that the air suction control component 80 blocks or releases the blockage of the communication between the third accommodation groove 14 and the air suction hole 12.

[0125] In an alternative embodiment, the third accommodation groove 14 can also communicate with the internal air suction flow channel 13, or communicate with both the air suction hole 12 and the internal air suction flow channel 13 at the same time. At this time, the air suction control component 80 blocks or releases the blockage of the communication between the third accommodation groove 14 and the internal air suction flow channel 13, or the communication between the third accommodation groove 14 and both of them, which can be selected according to actual needs.

[0126] Specifically, as Figure 21 shown, a middle notch is provided at the top of the base 60, and the air suction control component 80 is arranged in the middle notch, that is, below the workbench 10.

[0127] As Figure 21 and 24 shown, the air suction control component 80 includes a blocking member 81, a slide rail structure 82, and a fourth elastic member 83. The top end of the blocking member 81 extends into the third accommodation groove 14. The blocking member 81 is horizontally movably connected to the slide rail structure 82. The two ends of the fourth elastic member 83 are respectively connected to the blocking member 81 and the base 60, so that the blocking member 81 keeps blocking the communication between the third accommodation groove 14 and the air suction hole 12 in the initial state. The third driving mechanism 70 pushes the blocking member 81 to move, so that the blocking member 81 releases the blockage of the communication between the third accommodation groove 14 and the air suction hole 12.

[0128] Specifically, as Figure 24 shown, the blocking member 81 includes a third main body part and a blocking part 811. The blocking part 811 is arranged at one end close to the fourth elastic member 83 and extends into the third accommodation groove 14 to play a blocking role. The third main body part is horizontally movably connected to the slide rail structure 82. The third accommodation groove 14 and the fourth elastic member 83 are on the same side of the camera module motor 100. Under the elastic force of the fourth elastic member 83, the blocking member 81 keeps a tendency to move closer to the camera module motor 100, so that the blocking part 811 fits and seals with the groove wall of the third accommodation groove 14 close to the camera module motor 100, thereby blocking the communication between the third accommodation groove 14 and the air suction hole 12.

[0129] Furthermore, as Figures 11 to 13 、 Figure 21As shown in the figure, the third driving mechanism 70 includes a fifth driving member 71 and a fourth connecting plate 72. The fifth driving member 71 is drivingly connected to the fourth connecting plate 72 and is used to drive the fourth connecting plate 72 to move along the Y-axis. The third driving mechanism 70 is located at one end of the workbench 10 away from the fourth elastic member 83. One end of the fourth connecting plate 72 has a hook portion 721, which extends into the middle notch of the base 60. After the circuit board 101 is bent, the fifth driving member 71 drives the fourth connecting plate 72 to move in the direction close to the camera module motor 100, so as to push the blocking portion 811 away from the camera module motor 100, thereby releasing the blockage of the communication between the third accommodating groove 14 and the air suction hole 12. At this time, since the third accommodating groove 14 communicates with the atmosphere, the negative pressure in the air suction hole 12 and the internal air suction flow channel 13 returns to normal pressure, and the adsorption and fixation of the camera module motor 100 are released.

[0130] As Figures 22 to 24 shown, there are multiple air suction holes 12. The multiple air suction holes 12 include at least one first air suction hole 121 and at least one second air suction hole 122 that are separately arranged. The first air suction hole 121 communicates with the internal air suction flow channel 13, and the second air suction hole 122 communicates with the third accommodating groove 14 and is correspondingly arranged with the air suction control assembly 80.

[0131] Specifically, a sinking groove 15 is further formed on the lower end surface of the workbench 10. The first air suction hole 121 communicates with the internal air suction flow channel 13 through the sinking groove 15. The sinking groove 15 is arranged at an interval from the third accommodating groove 14. Further, as Figure 22 shown, there is a step in the third accommodating groove 14. The second air suction hole 122 communicates downward to the lower end surface of the step. Correspondingly, the upper part of the blocking portion 811 is L-shaped. When the blocking portion 811 fits with the groove wall close to the camera module motor 100, it just seals the lower end surface of the step, thereby blocking the second air suction hole 122.

[0132] In this embodiment, there are multiple first air suction holes 121 and one second air suction hole 122, and the first air suction holes 121 and the second air suction hole 122 are arranged at intervals along the circumferential direction of the camera module motor 100.

[0133] In this embodiment, the above-mentioned driving members can be servo motors, cylinders or electric cylinders.

[0134] As Figure 3 shown, the bending device further includes a frame 90. The workbench 10, the first bending assembly 20, the limiting assembly 30 and the second bending assembly 40 are all arranged on the frame 90.

[0135] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: by setting two bending components to bend the circuit board 101 step by step, the bending of the circuit board 101 is more sufficient, and when the originally flat circuit board 101 is bent to a preset angle, it will not cause the bending failure of the circuit board 101 due to unexpected bending, ensuring the effective bending of the circuit board 101. Further, by setting the limiting component 30 to limit and fix the camera module motor 100, it is avoided that the circuit board is deformed during the operation of the second bending component, thereby improving the manufacturing yield of the camera module motor, and further ensuring the manufacturing yield of the camera module.
