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 the variable aperture camera module, the FPC-Coil (circuit board with coil) needs to be installed in the slots on both sides of the stator. There are coils and Hall on the FPC. After the FPC is energized, the current drives the actuator 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, which needs to be bent to match the structural parts for installation. However, in the current context of miniaturization of camera modules, the structural gap reserved between the circuit board and the slot is small. Therefore, this special-shaped circuit board needs to be bent to the slot on the side of the stator, which is difficult to assemble. The existing bending device cannot bend the circuit board accurately and efficiently, and it is difficult to ensure the manufacturing yield of the motor, which in turn affects the manufacturing yield of the camera module.

DETAILED DESCRIPTION

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

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

[0062] like Figure 1 to Figure 2 As 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 the two sides of the circuit board 101 have coils, and the coils have Halls. Correspondingly, the two sides of the stator 102 have slots 1021, and the coils and Halls on the two sides of the circuit board 101 need to be bent so as to be installed in the slots 1021. In other words, the coils and the Halls thereon are the to-be-bent portions 1011.

[0063] like Figure 3 , Figures 11 to 14 As 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 portion 21, which is located on the side of the workbench 10 and can be raised and lowered, and is used to drive the portion to be bent 1011 of the circuit board 101 to be bent upward at a first preset angle. The limiting assembly 30 is located above the workbench 10 and can be raised and lowered, and is used to limit and fix the camera module motor 100 after the portion to be bent 1011 is bent at the first preset angle. The second bending assembly 40 includes a second bending portion 41, which is located on the side of the workbench 10 and can be horizontally movably arranged, and is used to drive the portion to be bent 1011 to continue to bend inward at a second preset angle.

[0064] By setting two bending components to bend the circuit board 101 in steps, the bending of the circuit board 101 can be more complete, and when the originally flat circuit board 101 is bent to a preset angle, the circuit board 101 will not fail to bend due to unexpected bending, thereby ensuring the effective bending of the circuit board 101. Furthermore, by setting a limit component 30 to limit and fix the camera module motor 100, deformation of the circuit board during the working process of the second bending component is avoided, thereby improving the manufacturing yield of the camera module motor, and then ensuring the manufacturing yield of the camera module.

[0065] It should be noted that Figure 1 and Figure 2The figure shows three positions of the portion to be bent 1011. The portion to be bent 1011 in a horizontal state is an initial unbent state; the portion to be bent 1011 in an inclined state is a state after being bent by the first bending assembly 20, and the angle between the portion to be bent 1011 and the horizontal plane is a first preset angle; the portion to be bent 1011 in a vertical or substantially vertical state is a state after being bent by the second bending assembly 40, and the portion to be bent 1011 is installed in the slot 1021.

[0066] In this embodiment, the sum of the first preset angle and the second preset angle is 90°. That is, the portion to be bent 1011 is in a vertical state after two bends. Specifically, the range of the first preset angle is 70° to 80°. Correspondingly, the range of the first preset angle is 10° to 20°. It can be understood that the two bends can be divided into coarse 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. Fig.11 Correspondingly, the up and down direction is the Z-axis direction.

[0068] In this embodiment, if Figures 11 to 13 , Fig.15 As shown, there are two first bending assemblies 20 , and the two first bending assemblies 20 are symmetrically arranged relative to the workbench 10 , so as to perform bending processing on the to-be-bent portions 1011 on both sides of the circuit board 101 respectively.

[0069] Specifically, Fig.14 and Fig.16 As shown, the first bending portion 21 includes a first main body and a first bending head 211. The first main body is a vertically arranged plate-like structure, and the first bending head 211 extends from the top of the first main body toward the direction close to the workbench 10. The first bending head 211 has a first avoidance gap 212 on the side close to the workbench 10 for avoiding the workbench 10. Furthermore, the first bending head 211 has a contact slope 213 on the side close to the workbench 10, and the contact slope 213 contacts the portion to be bent 1011. It can be understood that the inclination angle of the contact slope 213 is equal to the first preset angle.

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

[0071] Further, such as Figures 11 to 13 As shown, the first bending assembly 20 also includes a first driving mechanism 22, which is drivingly connected to the first bending portion 21, and is used to drive 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 rise and fall. In this embodiment, for a reasonable layout, the first driving mechanism 22 is placed on one side of the second bending assembly 40, that is, arranged in parallel with the second bending assembly 40. In this case, the first connecting plate 222 is placed along the Y-axis direction. Furthermore, in order to enable the first bending portion 21 to completely detach from the workbench 10 to avoid interference, the first driving mechanism 22 also includes a second driving member 223 and a base plate. The first driving mechanism 22 is arranged on the base plate, and the second driving member 223 is driven and connected to the base plate, thereby driving the first driving mechanism 22, the first connecting plate 222 and the first bending portion 21 as a whole to move along the X-axis direction.

[0072] During the operation of the first bending assembly 20, the first bending portion 21 is located outside the range of the workbench 10 in an initial state, and 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, and when it continues to move upward from 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, such as Fig.17 shown.

[0073] In this embodiment, the limiting assembly 30 has a first floating stroke along the height direction, so that the limiting assembly 30 can flexibly limit and fix the camera module motor 100. Figures 4 to 7 As 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 connected to the first fixing member 32 in a floating manner up and down, and the lower end surface of the first floating member 33 is a 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, and the first elastic member 34 provides an elastic supporting force to the first floating member 33 so that the first floating member 33 has a first floating stroke.

[0074] Further, such as Figure 4As shown, the lifting mechanism 31 includes a support frame 311, a third driving member 312 and a cover plate 313. The support frame 311 is located on the side of the workbench 10 along 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, and the cover plate 313 is used to be connected and fixed with the first fixing member 32, thereby driving the first fixing member 32 and the first floating member 33 to move up and down.

[0075] Further, such as Figures 5 to 7 , Fig. 9 As shown, the limiting assembly 30 also includes a connecting member 39, the first floating member 33 is provided with a through hole 335, 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 with the first fixing member 32, the through hole 335 is provided with a limiting step for limiting and stopping the connecting member 39, 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 tightly attached to each other, 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 has 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 abuts against the limiting step in the through hole 335. Under the action of the elastic support force of the first elastic member 34, the connecting member 39 can have a certain length of movable section 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 connecting 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 the floating stroke, thereby preventing the circuit board 101 from being damaged due to the hard interference of the cover plate 313.

[0078] In this embodiment, the connecting member 39 is adapted to the size of the through hole 335 , thereby playing a vertical guiding role and constraining the first floating member 33 and the first fixed member 32 to have a relatively straight floating stroke.

[0079] In this embodiment, the lower end surface of the first fixing member 32 and the upper end surface of the first floating member 33 are both provided with receiving holes, 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] like Figures 5 to 7 , Figures 9 and 10 as well as Figure 22 to Figure 24 As shown, the lower end surface of the first floating member 33 is provided with a positioning pin 334, and the workbench 10 is provided with a positioning hole 11 adapted to the positioning pin 334. When the positioning pin 334 descends, it extends into the positioning hole 11. Through the above arrangement, the first floating member 33 can be accurately aligned with the workbench 10, thereby realizing accurate limit fixation of the camera module motor 100.

[0081] like Figures 5 to 7 , Figures 9 and 10 As shown, the lower end surface of the first floating member 33 is provided with a middle recess 331 for avoiding the first bending portion 21. The middle recess 331 is provided with a limiting portion 336, 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 recess 331 is also used to avoid the camera module motor 100. When the limiting component 30 limits and fixes the camera module motor 100, the two ends of the middle recess 331 of the first floating member 33 fit with the workbench 10, and the middle recess 331 is the position for limiting and fixing the camera module motor 100.

[0082] Generally, magnetic materials are injected inside the camera module motor 100. Specifically, the magnetic materials can be paramagnetic materials, such as iron-nickel materials. Therefore, the limit assembly 30 can be provided with a magnetic component to magnetically fix the camera module motor 100, thereby achieving a better limit and fixation effect on the camera module motor 100.

[0083] In this embodiment, if Figure 5 , Figures 7 to 10 As shown, the limit assembly 30 also includes a magnetic member 35, and the upper end surface of the first floating member 33 is provided with a first receiving groove 332, the first receiving groove 332 is connected to the middle recess 331, and at least a part of the magnetic member 35 is received in the first receiving groove 332, which is used to magnetically fix the camera module motor 100. Through the above arrangement, the magnetic member 35 can be designed to be embedded to reduce possible collision interference problems. Specifically, the first receiving groove 332 is arranged corresponding to the camera module motor 100.

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

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

[0086] In this embodiment, there are multiple first elastic members 34, and the multiple first elastic members 34 are symmetrically arranged relative to the center of the first floating member 33 along the Y-axis direction. It can be understood that the first elastic members 34 are also symmetrically arranged relative to the limiting portion 336, so that the limiting portion 336 can be used as a point of central moment balance as much as possible, and the limiting end surface is supported by the symmetrically arranged first elastic members 34 to be relatively flat, so that the limiting effect of the limiting portion 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] Furthermore, there are multiple connecting members 39, and the multiple connecting members 39 are symmetrically arranged along the Y-axis direction relative to the center of the first floating member 33. Through the above arrangement, the first fixing member 32 and the first floating member 33 can be evenly connected, so that the limiting end surface is as flat as possible. Furthermore, the connecting member 39 and the first elastic member 34 are staggered along the Y-axis direction, so that the connection and support of the two are more uniform, and the flatness of the limiting end surface is further ensured.

[0088] Further, such as Figures 7 to 9 , Fig.17 As shown, the middle recess 331 is provided with a second receiving groove 333, and the first receiving groove 332 is connected to the second receiving groove 333, that is, the first receiving groove 332, the second receiving groove 333 and the middle recess 331 are connected in sequence from top to bottom. A buffer 36 is provided at the bottom of the magnetic suction member 35, and at least a part of the buffer 36 is accommodated in the second receiving groove 333 and the bottom end protrudes downward from the surface of the middle recess 331. In other words, the lower end surface of the buffer 36 is lower than the surface of the middle recess 331, so that when the first floating member 33 is in contact with the workbench 10, the buffer 36 can first contact with the camera module motor 100 to better support the camera module motor 100 and avoid damage to the camera module motor 100.

[0089] In this embodiment, the deformation amount of the buffer 36 is greater than the gap difference between the surface of the middle recess 331 and the lower end surface of the buffer 36. Through the above arrangement, the buffer 36 can have enough deformation space to provide enough abutment space.

[0090] Furthermore, there are two buffer members 36 , which are located at both ends of the bottom of the magnetic member 35 , thereby improving the contact uniformity and stability with the camera module motor 100 .

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

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

[0093] In this embodiment, in order to reasonably utilize space, the first force measuring module 37 is disposed above the magnetic attraction member 35. Figures 7 and 8 As shown, the limiting assembly 30 also includes a second elastic member 38, and the two ends of the second elastic member 38 are respectively connected to the first force measuring module 37 and the magnetic member 35, thereby providing elastic supporting force for the magnetic member 35, so that the magnetic member 35 is limited downward to fix the camera module motor 100.

[0094] Specifically, a receiving recess is provided in the middle of the lower end surface of the first fixing member 32, and the first force measuring module 37 includes a fixed end and a measuring element, wherein the fixed end is located in the receiving recess and connected and fixed 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 member 35 have receiving holes respectively, and the two ends of the second elastic member 38 are respectively received in the two receiving holes.

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

[0096] During the floating and pressing process of the first floating member 33, although the first elastic member 34 will undergo a certain degree of collapse, if the collapse stage exceeds the elastic deformation section of the first elastic member 34, the first elastic member 34 may be damaged, or because the first floating member 33 is actually interfered by an object, although a certain floating and pressing process is performed by the first elastic member 34, if it is still pressed down after the floating and pressing process, it may cause an accident. Therefore, in this embodiment, a first force measuring module 37 is set to measure the force received by the first floating member 33 during the pressing process. Specifically, the first force measuring module 37 is connected to the first fixed member 32 via a controller, and the measurement value of the first force measuring module 37 is read by the controller, and the controller is provided with a pre-pressure value, and the maximum value of the pre-pressure value is controlled to be the maximum elastic force section before the first elastic member 34 collapses. For example, if the elastic collapse section of the first elastic member 34 is 10mm, the maximum value of the pre-pressure value is 0.25 (kgf / mm)*10mm, thereby preventing the first floating member 33 from exceeding the elastic deformation section.

[0097] Of course, the floating stroke of the limit assembly 30 driven downward from the initial position is greater than the maximum elastic force segment of the first elastic member 34 before collapse, so that the limit assembly 30 can drive the first fixed member 32 and the first floating member 33 to move downward, and realize the process from non-contact to elastic contact, so as to better pre-press the camera module motor 100.

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

[0099] In this embodiment, the second bending assembly 40 has a second floating stroke in the horizontal direction, so that the second bending assembly 40 can flexibly bend the portion to be bent 1011. Figures 11 to 13 As shown, the second bending assembly 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 a side of the second fixing member 43 close to the workbench 10 and is horizontally movably connected to the second fixing member 43, and the second bending portion 41 is connected to an end of the second floating member 44 close to the workbench 10. The two 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 preload force to the second floating member 44 so that the second floating member 44 has a second floating stroke.

[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 assembly 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 pre-pressure effect on the circuit board 101.

[0102] In this embodiment, if Fig.18 As shown, the first bending portion 21 of the first bending component 20 first pushes the portion to be bent 1011 upward for one bend, and then the first floating member 33 of the limiting component 30 can realize the supporting effect on the upper end surface of the camera module motor 100, and then the second bending portion 41 of the second bending component 40 continues to push the portion to be bent 1011 horizontally inward for a second bend, and the second floating member 44 can provide a supporting effect on the side surface of the circuit board 101, thereby realizing a floating pre-pressure effect on the upper end surface and the side surface of the circuit board 101 at the same time, so that the limiting and fixing effect of the circuit board 101 is better, and it is prevented that the surface of the circuit board 101 is pressed on one side, such as pressing the side surface of the circuit board 101 on one side or pressing the upper end surface of the circuit board 101 on one side, resulting in excessive freedom of the circuit board 101 and deformation in other directions.

[0103] In this embodiment, if Fig.14 As shown, there are two second bending parts 41, and the two second bending parts 41 are symmetrically arranged on both sides of the first bending part 21. Specifically, the second bending part 41 includes a second main body and a second bending head 411, and the second bending head 411 is arranged on a side of the second main body close to the workbench 10. A limiting recess is provided on the side where the two second bending heads 411 are close to each other, respectively corresponding to the two ends of the part to be bent 1011. When the second bending head 411 contacts the part to be bent 1011, the two ends of the part to be bent 1011 extend into the two limiting recesses respectively, thereby ensuring that the part to be bent 1011 does not deviate during the bending process.

[0104] In this embodiment, if Fig.19 As 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 , thereby driving the second connecting plate 422 to move along the X-axis direction.

[0105] like Figures 11 to 13 , Fig.19 As shown, an elastic force adjusting member 46 is disposed 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 disposed horizontally and movably for adjusting the magnitude of the elastic preload force.

[0106] Specifically, Fig.19As shown, the second fixing member 43 includes a third connecting plate 431, the elastic adjustment member 46 is arranged on the side of the third connecting plate 431 away from the second floating member 44, and a slide rail along the X-axis direction is arranged 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, such as Fig.19 As shown, the second bending assembly 40 further includes a second force measuring module 48, which is disposed on the third connecting plate 431 and between the elastic force adjusting member 46 and the second floating member 44, and is used to measure the force exerted on the second floating member 44. One end of the third elastic member 45 is connected to the second force measuring module 48, that is, 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 a gear rack structure, which can convert rotational motion into linear motion. Of course, other structural forms such as cam top rod, crank rocker, worm gear, screw nut, etc. can also be adopted. By extending or retracting the abutment joint at one end of the elastic force adjusting member 46, the elastic preload force of the third elastic member 45 can be controlled.

[0109] Further, such as Fig.19 As shown, the second fixing member 43 further includes a Y-axis displacement mechanism 432 and a Y-axis adjustment 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 that it can move along the Y-axis relative to the second connecting plate 422. The Y-axis adjustment member 433 can also be a knob structure, so as to control the Y-axis displacement length of the third connecting plate 431.

[0110] Furthermore, the second fixing member 43 further includes a limiting member 434, which is disposed on a side of the third connecting plate 431 close to the workbench 10, and a limiting groove is correspondingly provided on the outer side of the second floating member 44 along the X-axis direction, and the limiting member 434 extends into the limiting groove, thereby limiting the left and right positions of the second floating member 44 in the X-axis direction. Through the above arrangement, 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 preload force.

[0111] In this embodiment, corresponding to the two second bending portions 41 , there are two second floating members 44 , two third elastic members 45 , two elastic force adjusting members 46 and two limiting members 434 , and the two members are spaced apart along the Y-axis direction.

[0112] In this embodiment, the connection between 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. In other words, the connection between 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 adjustment 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 adjustment member 46 and the third elastic member 45 in this embodiment are asymmetrically arranged with the second floating member 44, so the elastic preload provided to the second floating member 44 by the second floating member 44 and the third elastic member 45 is asymmetrical, and by applying different elastic preloads to the second floating member 44, under the influence of the torque, the position of the second floating member 44 can be affected, and then the position of the second bending portion 41 is affected, especially along the curvature of the contact point between the third elastic member 45 and the second floating member 44, so that 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, the circuit board 101 needs to be attached to the base after being bent, and no exposed part of the circuit board 101 is allowed. The 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 preload force provided to the second floating part 44 by the elastic adjustment part 46. Under the influence of the torque, the position state of the second bending part 41 can be ultimately 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 boards of different circuit boards 101 is inconsistent, local micro-settings are required. Micro-adjustments are made according to the actual size after bending. The camera module motor 100 is photographed after bending to confirm the gap between the circuit board 101 and the stator 102 after bending. After the camera module motor 100 is laid flat, photographs are taken from top to bottom for measurement. If there is a gap, adjustment is required.

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

[0117] like Fig. 20 As shown, the second bending assembly 40 further includes a heating assembly 47, which is disposed in the second bending portion 41 and is used to heat the portion to be bent 1011. Specifically, after the second bending portion 41 completes the secondary bending of the circuit board 101, the heating assembly 47 starts to work and heats and cures the circuit board 101.

[0118] Further, such as Fig. 20As shown by the dotted line, the heating assembly 47 includes a heating element 471 and a temperature measuring element 472. The heating element 471 is located on the 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 determine whether the heating temperature exceeds the standard value during the hot pressing process. By providing an embedded heating assembly 47, the circuit board 101 becomes softer and will not return to its original state after being bent and cooled to room temperature, thereby improving the yield of 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, such as Fig.19 As shown, the second bending assembly 40 further includes a heat insulation board 49 , and the second bending portion 41 and the second floating member 44 are connected via the heat insulation board 49 , thereby playing a role of heat insulation and heat preservation, thereby improving the heating efficiency of the heating assembly 47 .

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

[0121] like Figures 11 to 13 , Figure 22 to Figure 24 As shown, the bending device also includes an air suction component 50, the workbench 10 is provided with an air suction hole 12 and an internal air suction flow channel 13 connected to the air suction hole 12, the air suction hole 12 is arranged corresponding to the camera module motor 100, and the air suction component 50 is connected to the internal air suction flow channel 13, and is used to perform an air suction operation to adsorb and fix the camera module motor 100.

[0122] Specifically, Fig.21 As shown, the suction component 50 includes a suction connector 51 and a suction piece. The suction connector 51 is arranged at one end of the workbench 10 and is connected to the internal suction flow channel 13. The suction piece is connected to the suction connector 51 through an air pipe, thereby performing a suction operation to adsorb and fix the camera module motor 100.

[0123] In this embodiment, the air intake hole 12 is vertically arranged and the internal air intake flow channel 13 is horizontally arranged, that is, the air intake air path is a path that first goes downward and then outward. The above-mentioned air path arrangement can enable multiple air intake holes 12 to be arranged, thereby improving the adsorption and fixing effect.

[0124] Further, such as Figures 11 to 13 , Fig.21As shown, the bending device also includes a base 60, a third driving mechanism 70 and an air suction control assembly 80. The workbench 10 is arranged on the top of the base 60, and the workbench 10 is provided with a third accommodating groove 14 that runs through from top to bottom, and the third accommodating groove 14 is connected to the air suction hole 12. The air suction control assembly 80 is arranged on the base 60 and at least a part of it extends into the third accommodating groove 14. The third driving mechanism 70 is drivingly connected to the air suction control assembly 80, and the third driving mechanism 70 drives the air suction control assembly 80 to move relative to the workbench 10, so that the air suction control assembly 80 blocks or unblocks the connection between the third accommodating groove 14 and the air suction hole 12.

[0125] In an optional embodiment, the third accommodating groove 14 can also be connected to the internal intake air duct 13, or be connected to the intake hole 12 and the internal intake air duct 13 at the same time. At this time, the intake control component 80 blocks or unblocks the connection between the third accommodating groove 14 and the internal intake air duct 13, or the connection between the third accommodating groove 14 and both, which can be selected according to actual needs.

[0126] Specifically, Fig.21 As shown, a middle gap is formed on the top of the base 60 , and the suction control assembly 80 is arranged in the middle gap, that is, located below the workbench 10 .

[0127] like Fig.21 and 24 As shown, the air intake control assembly 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 receiving 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 connection between the third receiving groove 14 and the air intake hole 12 in the initial state, and the third driving mechanism 70 pushes the blocking member 81 to move, so that the blocking member 81 unblocks the connection between the third receiving groove 14 and the air intake hole 12.

[0128] Specifically, Fig.24 As shown, the blocking member 81 includes a third main body and a blocking portion 811. The blocking portion 811 is arranged at one end close to the fourth elastic member 83 and extends into the third accommodating groove 14 to play a blocking role. The third main body is horizontally movably connected to the slide rail structure 82. The third accommodating groove 14 and the fourth elastic member 83 are located on the same side of the camera module motor 100. Under the elastic force of the fourth elastic member 83, the blocking member 81 maintains a tendency to move closer to the camera module motor 100, so that the blocking portion 811 and the groove wall of the third accommodating groove 14 close to the camera module motor 100 are sealed, thereby blocking the connection between the third accommodating groove 14 and the air intake hole 12.

[0129] Further, such as Figures 11 to 13 , Fig.21As shown, the third driving mechanism 70 includes a fifth driving member 71 and a fourth connecting plate 72, and 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, thereby pushing the blocking portion 811 away from the camera module motor 100, thereby unblocking the connection between the third accommodating groove 14 and the air intake hole 12. At this time, since the third accommodating groove 14 is connected to the atmosphere, the negative pressure in the air intake hole 12 and the internal air intake channel 13 returns to normal pressure, and the adsorption and fixation of the camera module motor 100 are released.

[0130] like Figure 22 to Figure 24 As shown, there are multiple air intake holes 12, including at least one first air intake hole 121 and at least one second air intake hole 122 that are isolated from each other. The first air intake hole 121 is connected to the internal air intake flow channel 13, and the second air intake hole 122 is connected to the third accommodating groove 14 and is correspondingly arranged with the air intake control component 80.

[0131] Specifically, a sink 15 is formed on the lower end surface of the workbench 10, and the first air intake hole 121 is connected to the internal air intake channel 13 through the sink 15. The sink 15 and the third receiving groove 14 are spaced apart. Fig. 22 As shown, the third accommodating groove 14 has a step in it, and the second air intake hole 122 is downwardly connected 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 is in contact with the groove wall close to the camera module motor 100, the lower end surface of the step is sealed, thereby blocking the second air intake hole 122.

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

[0133] In this embodiment, the above-mentioned driving components may be servo motors, air cylinders or electric cylinders.

[0134] like Figure 3 As shown, the bending device also includes a frame 90 , and 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-mentioned embodiment of the present invention achieves the following technical effects: by setting two bending components to bend the circuit board 101 in steps, the bending of the circuit board 101 is made more complete, and the originally flat circuit board 101 will not fail to bend due to unexpected bending when it is bent to a preset angle, thereby ensuring the effective bending of the circuit board 101. Furthermore, by setting a limit component 30 to limit and fix the camera module motor 100, deformation of the circuit board during the working process of the second bending component is avoided, thereby improving the manufacturing yield of the camera module motor, and then ensuring the manufacturing yield of the camera module.
