Description

Technical Field

[0001] The present application relates to the field of electronic product manufacturing, and in particular to a feeding device used for lens assembly. Background Art

[0002] During the assembly of electronic products with cameras, such as mobile phones, the camera module requires a base plate. The base plate consists of a high-temperature base film and a frame. The high-temperature base film is located at the bottom of the frame and is adhesive. The FPC module, to which the camera is soldered, is then adhered to the base plate. The voice coil motor, a key component for adjusting the camera's focal length, requires pre-applying glue to the FPC module. The voice coil motor is then glued and fixed to the FPC module, and the camera cover is placed inside, ultimately completing the camera module.

[0003] In the related technology, a camera module installation device is disclosed. The device includes a first assembly line and a second assembly line. During the assembly production process, the first assembly line transports the substrate carrying the FPC, and the second assembly line transports the voice coil motor, chip and other materials that need to be added to the FPC module. The first assembly line needs to go through processes such as gluing and welding. Finally, the materials on the first and second assembly lines are transported to the same side and assembled.

[0004] Regarding the above-mentioned related technologies, there are the following defects: there are differences in the transmission time of the FPC module and the voice coil motor on different assembly lines, resulting in low efficiency when installing the camera module. Summary of the Invention

[0005] In order to improve the installation efficiency of the camera module, the present application provides a feeding device for lens assembly.

[0006] The present application provides a feeding device for lens assembly using the following technical solutions:

[0007] A feeding device for lens assembly includes a frame, the frame being provided with a first feeding mechanism, a second feeding mechanism, a gluing mechanism, a transfer mechanism, and a gripping mechanism. The transfer mechanism is disposed between the first feeding mechanism and the second feeding mechanism. The first feeding mechanism is used to convey a voice coil motor, the second feeding mechanism is used to convey a substrate with an FPC module adhered thereto, and the gluing mechanism is connected to the second feeding mechanism and is used to gluing the FPC module.

[0008] The grabbing mechanism includes a first grabbing mechanism and a second grabbing mechanism. The first grabbing mechanism is installed between the first feeding mechanism and the transfer mechanism, and is used to grab the voice coil motor and transfer it to the transfer mechanism. The second grabbing mechanism is installed between the second feeding mechanism and the transfer mechanism, and is used to grab the voice coil motor and bond it to the FPC module on the second feeding mechanism.

[0009] By adopting the above technical solution, the voice coil motor and the FPC module are respectively conveyed to the position close to the transfer mechanism by the first feeding mechanism and the second feeding mechanism, and the voice coil motor is transferred to the transfer mechanism by the first grasping mechanism. The transfer mechanism transfers the voice coil motor to the side close to the second feeding mechanism, and the voice coil motor on the transfer mechanism is transferred to the top of the FPC module by the second grasping mechanism, and the voice coil motor is positioned and installed.

[0010] By installing a transfer mechanism between the first and second feeding mechanisms, the time difference between the first and second feeding mechanisms in transporting their respective materials is reduced, improving material transfer efficiency. With the transfer mechanism in place, the transfer mechanism, the first gripping mechanism, and the second gripping mechanism can operate simultaneously during the same time period, achieving simultaneous gripping, transfer, and installation, greatly improving camera module installation efficiency.

[0011] Optionally, the first feeding mechanism includes a first guide rail, a feed tray and a first drive assembly, the first guide rail is installed on the frame along the feeding direction, the feed tray is used to place the voice coil motor, the feed tray is slidably connected to the first guide rail, and the sliding direction is consistent with the installation direction of the first guide rail. The first drive assembly is arranged on the frame to drive the feed tray to slide.

[0012] By adopting the above technical solution, the voice coil motor to be installed is placed in the feed tray, and the first guide rail can provide the feed tray with a support for the voice coil motor. Driven by the first drive component, the feed tray moves on the first guide rail and approaches the transfer mechanism to realize the feeding function of the voice coil motor.

[0013] Optionally, the second feeding mechanism includes a second guide rail, a flow tray and a second drive assembly, the second guide rail is installed on the frame, the flow tray is slidably installed on the second guide rail for placing the substrate, and the second drive assembly is arranged on the frame for driving the flow tray to slide.

[0014] By adopting the above technical solution, the flow tray with the substrate bonded with the FPC module is placed on the second guide rail. The second guide rail can carry the flow tray. Under the drive of the second drive component, the flow tray moves on the second guide rail and approaches the transfer mechanism to realize the feeding function of the FPC module.

[0015] Optionally, the second feeding mechanism also includes a pressing frame, which is connected to the second guide rail and can press and fix the flow tray; the gluing mechanism includes a gluing gun and a movable control component, which is installed on the frame and can control the gluing gun to glue on the FPC module.

[0016] By employing this technical solution, when gluing the FPC module or installing the voice coil motor, the press frame can press and secure the flow tray to the second guide rail, minimizing the impact of minor movement of the flow tray on gluing or installation accuracy. The glue gun, controlled by the motion control assembly, can be moved in space. When the flow tray with the FPC module installed moves under the glue mechanism, the glue gun can accurately apply glue to each FPC module, preparing for the voice coil motor attachment.

[0017] Optionally, the transfer mechanism includes a turntable, a carrying plate and a third driving member, the carrying plate is fixedly set on the frame, the turntable is rotatably connected to the carrying plate, the third driving member is set on the frame, and is used to drive the turntable to rotate, and the turntable is provided with a placement groove for accommodating the voice coil motor.

[0018] By adopting this technical solution, the carrier plate supports the turntable to improve its stability. The third drive element drives the turntable to rotate. The placement grooves on the turntable limit the voice coil motor, effectively preventing it from being thrown off the turntable due to centrifugal force during rotation. Rotating the turntable rotates the voice coil motor from one side of the first feeding mechanism to the second feeding mechanism. The use of the turntable reduces the transport distance required by the first and second gripping mechanisms, thereby improving the transport and installation efficiency of the voice coil motor.

[0019] Optionally, the transfer mechanism also includes a fixed component, which includes a No. 1 rack, a No. 2 rack, a driving gear and a driving rack. The No. 1 rack and the No. 2 rack are both slidably connected in the turntable, and the sliding directions are opposite. The driving gear is meshed with the No. 1 rack and the No. 2 rack to drive the No. 1 rack and the No. 2 rack to slide. When the No. 1 rack and the No. 2 rack slide toward each other, they can be used to clamp the voice coil motor; the driving rack is meshed with the driving gear to drive the driving gear to rotate; the driving rack is slidably connected to the turntable, and the sliding direction is the direction of approaching or moving away from the turntable. A fourth driving member is provided on the carrier plate, and the fourth driving member is used to make the driving rack slide.

[0020] With this technical solution, the voice coil motor is placed in the slot. Due to the gap between the voice coil motor and the slot, the moment the turntable begins to rotate, the inertia of the delicate internal structure of the voice coil motor can cause it to slide and collide with the sidewalls of the slot, potentially damaging the motor. Therefore, the voice coil motor must be secured with a fixing assembly before it can rotate.

[0021] The fourth driving member drives the driving rack to move, and the driving rack drives the driving gear to rotate. After the driving gear rotates, it can drive the No. 1 rack and the No. 2 rack to move simultaneously towards the direction close to or away from the voice coil motor, and finally realize the clamping and release of the voice coil motor. When the turntable rotates, the voice coil motor is in a clamped state, and when the voice coil motor needs to be grasped, the fixing component is in a released state. The use of the fixing component can effectively reduce the risk of the voice coil motor being damaged by impact in the placement slot.

[0022] Optionally, a weighted ball is rotatably mounted on the driving rack, and the weighted ball can abut against the fourth driving member. The supporting plate is provided with an arc-shaped groove along the circumference of the turntable, and the weighted ball can roll in the groove. When the fourth driving member drives the weighted ball to approach the turntable, the weighted ball disengages from the groove and rolls on the surface of the supporting plate as the turntable rotates, and the voice coil motor is in a clamped state.

[0023] By adopting the above technical solution, when the weighted ball is in the sink, the weighted ball pulls the drive rack down to the lowest point. At this time, the fixing assembly is in an unfixed state. After the fourth drive assembly lifts the weighted ball, the drive rack is pushed to the highest point by the weighted ball. At this time, the fixing assembly fixes the voice coil motor. After the turntable starts to rotate, the weighted ball rolls to the upper surface of the carrier plate and away from the sink. During the entire process of the weighted ball rolling on the carrier plate, the voice coil motor is always fixed by the fixing assembly. When the weighted ball rotates to the sink position, the weighted ball falls into the sink due to gravity and drives the drive rack to move to release the lock of the fixed assembly on the voice coil motor. In this way, the voice coil motor is in a fixed state during transportation and is unfixed when it needs to be grabbed and transferred.

[0024] Optionally, both the No. 1 rack and the No. 2 rack are slidably connected with abutment rods, and the sliding direction is the direction of approaching or moving away from the voice coil motor. Buffer springs are installed between the abutment rod and the No. 1 rack, and between the abutment rod and the No. 2 rack.

[0025] With this technical solution, when clamping the voice coil motor, racks 1 and 2 approach the motor, causing the abutment rod to first contact the motor. As racks 1 and 2 continue to move, the abutment rod slides under force, compressing the spring to better grip the motor. During clamping, the abutment rod and spring work together to gradually increase the force applied to the motor, effectively protecting it from damage during the clamping process.

[0026] Optionally, the first grabbing mechanism includes a first movable control component and a material picking head, the first movable control component is slidably installed on the frame, and the sliding direction is the direction of approaching or moving away from the first feeding mechanism, and the frame is provided with a fifth drive component for driving the first movable control component to slide; the material picking head is connected to the first movable control component, and the first movable control component is used to control the material picking head to grab the transfer voice coil motor to the middle turntable.

[0027] By adopting this technical solution, the fifth drive assembly controls the first motion control assembly to move on the frame, positioned between the central turntable and the first feeding mechanism. Under the control of the first motion control assembly, the pick-up head moves above the first feeding mechanism, grabs the voice coil motor, transfers it, and places it on the central turntable. This ultimately achieves the function of transferring the voice coil motor to the central turntable.

[0028] Optionally, the second grabbing mechanism includes a second movable control component and a mounting head, the second movable control component is slidably mounted on the frame, and the sliding direction is the direction of approaching or moving away from the second feeding mechanism, and the frame is provided with a sixth drive component for driving the second movable control component to slide; the mounting head is connected to the second movable control component, and the second movable control component is used to control the mounting head to grab the voice coil motor from the turntable and transfer and paste it to the FPC module.

[0029] By employing this technical solution, the sixth drive assembly controls the second motion control assembly to move on the frame, positioned between the central turntable and the second feed mechanism. Under the control of the second motion control assembly, the mounting head moves above the central turntable, grabs the voice coil motor, transfers it, and attaches it to the FPC module, ultimately completing the voice coil motor installation and attachment process.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a feeding device for lens assembly. Figure 1 A feeding device for lens assembly includes a frame 1, a first feeding mechanism 11, a second feeding mechanism 12, a gluing mechanism 2, a transfer mechanism 3, and a gripping mechanism 4. The first feeding mechanism 11 and the second feeding mechanism 12 are mounted parallel to the frame 1. The transfer mechanism 3 is mounted on the frame 1 and located between the first feeding mechanism 11 and the second feeding mechanism 12. The voice coil motor 6 is transferred from one end of the first feeding mechanism 11 to one end of the transfer mechanism 3. The gluing mechanism 2 is mounted on the second feeding mechanism 12. The FPC module 5 is transferred by the second feeding mechanism 12 to the position below the gluing mechanism 2 for gluing. After gluing is completed, the FPC module 5 is transferred by the second feeding mechanism 12 to the transfer mechanism 3.

[0038] The gripping mechanism 4 is mounted on the frame 1 and located above the transfer mechanism 3. It comprises a first gripping mechanism 41 and a second gripping mechanism 42, both mounted on the frame 1. The first gripping mechanism 41 grabs the voice coil motor 6 and transfers it to the transfer mechanism 3. The transfer mechanism 3 rotates, transferring the voice coil motor 6 from the side near the first feeding mechanism 11 to the side near the second feeding mechanism 12. The second gripping mechanism 42 then grabs the voice coil motor 6, transfers it to the second feeding mechanism 12, and affixes it to the FPC module 5, ultimately completing the installation of the voice coil motor 6.

[0039] By providing the first gripping mechanism 41, the second gripping mechanism 42, and the transfer mechanism 3, the installation process of the voice coil motor 6 is split. By using the transfer mechanism 3 to transfer the voice coil motor 6, the travel distance of the first gripping mechanism 41 and the second gripping mechanism 42 is shortened, allowing transfer and installation to be performed simultaneously. This method improves the installation efficiency of the voice coil motor 6. Furthermore, the provision of the transfer mechanism 3 reduces the time difference between the first and second feeding mechanisms when delivering their respective materials.

[0040] Reference Figure 1 The first feeding mechanism 11 includes a first guide rail 111, bolted to the frame 1. The first guide rail 111 extends along the feeding direction to one side of the transfer mechanism 3. A feed tray 112 is slidably mounted on the first guide rail 111 via a pulley (not shown). The voice coil motors 6 are arranged and placed within the feed tray 112. A first drive assembly (not shown) is also mounted on the mounting platform. In this embodiment, the first drive assembly comprises a servo motor, a lead screw, and a push plate. The servo motor is bolted to the frame 1 and connected to the lead screw, driving its rotation. The push plate has a threaded hole through which it is rotatably connected to the lead screw. Rotation of the lead screw drives the push plate to slide on the first guide rail 111, which in turn pushes the feed tray 112. Driven by the first drive assembly, the feed tray 112 moves to the transfer mechanism 3, ultimately enabling the voice coil motor 6 to load the material.

[0041] The second feeding mechanism 12 includes a second guide rail 121, which is bolted to the frame 1 and extends along the feed direction to one side of the transfer mechanism 3. A gluing mechanism 2 is also mounted on the mounting platform. The gluing mechanism 2 includes a gluing gun 21 and a motion control assembly 22. In this embodiment, the motion control assembly 22 is a robotic arm (not shown). The gluing gun 21 is bolted to the robotic arm and, under the control of the robotic arm, can move in the X-axis, Y-axis, and Z-axis directions (the X-axis, Y-axis, and Z-axis are mutually perpendicular). The robotic arm controls the gluing gun 21 to apply glue to each FPC module 5.

[0042] The second feeding mechanism 12 also includes a flow tray 122 and a second drive assembly (not shown). The second drive assembly (not shown) includes a servo motor, a lead screw, and a push plate. The servo motor is bolted to the frame 1 and connected to the lead screw, driving the lead screw to rotate. The push plate has a threaded hole through which it is rotatably connected to the lead screw. When the lead screw rotates, the push plate slides on the second guide rail 121, pushing the flow tray 122. The substrate with the FPC module 5 attached is placed on the flow tray 122. Driven by the second drive assembly, the FPC module 5 moves to the bottom of the glue applying mechanism 2. A cylinder (not shown) is also bolted to the second guide rail 121. A pressure frame 123 is bolted to the cylinder. The cylinder controls the pressure frame 123 to press downward to secure the substrate and flow tray 122. After the substrate and flow tray 122 are secured, the glue gun 21 glues the FPC modules 5 one by one. After the gluing is completed, the cylinder controls the pressing frame 123 to move upward to release the fixation of the substrate and the flow plate 122, and the second driving assembly continues to push the flow plate 122 to the position of the transfer mechanism 3 for the subsequent installation of the voice coil motor 6.

[0043] Refer to 1 and Figure 2 The transfer mechanism 3 includes a turntable 31, a carrier plate 32, a third driver (not shown), and a fixing assembly 33. The turntable 31 is coaxially connected to the carrier plate 32, which is bolted between the first feed mechanism 11 and the second feed mechanism 12. In this embodiment, the third driver is a servo motor, bolted to the frame 1. The servo motor is connected to the turntable 31 and controls the rotation of the turntable 31. The top surface of the turntable 31 has multiple placement slots 311, in which the voice coil motor 6 is placed. Clockwise rotation of the turntable 31 transfers the voice coil motor 6 from the first feed mechanism 11 to the second feed mechanism 12. In this embodiment, the turntable 31 has four placement slots 311, with the angle between adjacent placement slots 311 being 90°. Each rotation of the turntable also involves a 90° angle. The first grabbing mechanism 41 places the voice coil motor 6 in the placement groove 311 close to the first feeding mechanism 11, and the second grabbing mechanism 42 grabs the voice coil motor 6 in the placement groove 311 close to the second feeding mechanism 12 and sticks it to the FPC module 5.

[0044] Due to the gap between the voice coil motor 6 and the placement groove 311, when the turntable 31 starts to rotate from a stationary state, the voice coil motor 6 slides and hits the side wall of the placement groove 311 due to inertia and centrifugal force. After rotating 90°, the turntable 31 returns from a rotating state to a stationary state, and the voice coil motor 6 slides and hits the side wall on the opposite side of the placement groove 311 for the second time, causing a secondary impact. The repeated impacts increase the risk of damage to the voice coil motor 6.

[0045] Reference Figure 1 and Figure 2 To reduce the risk of damage to the voice coil motor 6 caused by the sidewalls of the placement slots 311 striking the voice coil motor 6 during rotation, a securing assembly 33 is installed in each placement slot 311. Before the turntable 31 rotates, the securing assembly 33 secures the voice coil motor 6 within the placement slot 311, preventing it from striking the sidewalls during rotation. When the voice coil motor 6 rotates to the side of the second feeding mechanism 12, the securing assembly 33 releases the securing assembly, allowing the second gripping mechanism 42 to smoothly grip and install the voice coil motor 6.

[0046] The fixing assembly 33 includes a first rack 331, a second rack 332, a drive gear 333, and a drive rack 334. The first rack 331 and the second rack 332 are slidably mounted on the turntable 31. The first rack 331 and the second rack 332 are mounted opposite each other on opposite sides of the placement slot 311. The first rack 331 and the second rack 332 slide into the placement slot 311, relatively close to each other, and clamp the voice coil motor 6 in the placement slot 311. The No. 1 rack 331 and the No. 2 rack 332 are provided with gear teeth, and the driving gear 333 is rotatably installed on the turntable 31. The No. 1 rack 331 and the No. 2 rack 332 are simultaneously engaged with the driving gear 333 through the gear teeth. The driving gear 333 is located between the No. 1 rack 331 and the No. 2 rack 332. When the driving gear 333 rotates, the No. 1 rack 331 and the No. 2 rack 332 slide simultaneously due to the mutual engagement of the gear teeth, thereby clamping and fixing the voice coil motor 6.

[0047] Reference Figure 2 and Figure 3 Abutment rods 336 and springs 337 are mounted on both the first and second racks 331, 332. The abutment rod 336 is coaxially mounted within the first rack 331 and can slide relative to it. A spring 337 is mounted within the first rack 331, with one end of the spring 337 contacting the abutment rod 336 and the other end contacting the first rack 331. A similar abutment rod 336 and spring 337 are also mounted within the second rack 332. During the clamping and securing process of the voice coil motor 6, the first and second racks 331, 332, approach each other. The abutment rods 336 on either side first contact the voice coil motor 6. After contact, the thrust of the abutment rods 336 compresses the springs 337, eventually stopping compression and securing the voice coil motor 6. When the voice coil motor 6 is clamped using the above solution, the force applied to the voice coil motor 6 gradually increases, and the abutment rod 336 pushes the spring 337 for compression buffering, thereby reducing the risk of deformation of the voice coil motor 6 during clamping.

[0048] Reference Figure 4The drive rack 334 is also equipped with gear teeth and is vertically mounted on the turntable 31 and meshes with the drive gear 333. When the drive rack 334 is moved upward, it drives the drive gear 333 to rotate, thereby controlling the first and second racks 331, 332 to clamp the voice coil motor 6. A groove 322 is provided on the carrier plate 32. A weighted ball 335 is rotatably mounted on the drive rack 334 near one end of the carrier plate 32. The weighted ball 335 pulls the drive rack 334 downward to its lowest point under gravity. During this downward movement, it rotates the drive gear 333, moving the first and second racks 331, 332 away from the voice coil motor 6, thereby unlocking the voice coil motor 6.

[0049] Reference Figure 4 and Figure 5 The sink 322 is semicircular in shape. Its terminal end is located directly below the placement slot 311 on the side closest to the second feeding mechanism 12, while its initial end is located directly below the placement slot 311 on the side closest to the first feeding mechanism 11. The path from the terminal end along the placement slot 311 to the initial end is the opening position of the sink 322. The fourth drive member 321 of this embodiment is a cylinder, mounted on the carrier plate 32 via bolts and located at the initial end of the sink 322.

[0050] Initially, the voice coil motor 6 is placed from the feed tray 112 into the placement slot 311. The weighted ball 335 below the placement slot 311 is located at the starting point within the sink 322. The fourth drive member 321 lifts the weighted ball 335 away from the sink 322. When the weighted ball 335 reaches the upper surface of the carrier tray 32, the fourth drive member 321 stops. As the weighted ball 335 rises, it pushes the drive rack 334 upward. The drive rack 334 rotates the drive gear 333, causing the first and second racks 331 and 332 to approach the voice coil motor 6, securing it within the placement slot 311.

[0051] The turntable 31 then begins to rotate, and the weighted ball 335 rotates with it. It rolls away from the fourth drive member 321 and onto the upper surface of the carrier plate 32, where it continues to roll. As the voice coil motor 6 rotates toward the second feed mechanism 12, the weighted ball 335 continues to roll on the upper surface of the carrier plate 32, keeping the voice coil motor 6 clamped and secured. After the weighted ball 335 leaves the fourth drive member 321, the fourth drive member 321 descends and returns to its initial position. When the voice coil motor 6 reaches the second feed mechanism 12, the turntable 31 stops rotating. The weighted ball 335 then falls under gravity into the terminal end of the trough 322. The drive rack 334 descends, driving the drive gear 333 in the opposite direction. The first and second racks 331, 332 slide away from the voice coil motor 6, effectively unlocking the voice coil motor 6.

[0052] After the voice coil motor 6 is grasped and mounted by the second grasping mechanism 42, the intermediate turntable 31 continues to rotate. During this process, the weighted ball 335 remains within the groove 322, rolling and rotating toward the starting position of the groove 322. The fixing assembly 33 remains unlocked, ready to clamp the next voice coil motor 6. This ensures that the voice coil motor 6 remains fixed throughout the entire transportation process, thereby reducing the possibility of impact damage to the voice coil motor 6.

[0053] Reference Figure 2 The first grasping mechanism 41 includes a first motion control assembly 411, a fifth drive assembly (not shown), and a pick-up head 412. The pick-up head 412 is mounted on the first motion control assembly 411. In this embodiment, the pick-up head 412 is made of rubber. When it contacts the voice coil motor 6, it deforms and effectively adheres to the voice coil motor 6. In this embodiment, the first motion control assembly 411 is a robotic arm that controls the movement of the pick-up head 412 in the X, Y, and Z axes (the X, Y, and Z axes are perpendicular to each other). The first motion control assembly 411 controls the pick-up head 412 to grasp the voice coil motor 6 and transfer it to the placement slot 311. The fifth drive assembly comprises a servo motor and a lead screw. The servo motor is mounted within the frame 1 and connected to the lead screw. The servo motor drives the lead screw to rotate. The lead screw is connected to the robotic arm, and its rotation controls the movement of the robotic arm. Under the control of the first movement control component 411 and the fifth driving component, the material taking head 412 moves between the transfer mechanism 3 and the first feeding mechanism 11 .

[0054] An air pump (not shown) is connected to the material picking head 412 through a pipeline. The air pump is installed in the frame 1. The air pump generates negative pressure on the material picking head 412. The negative pressure sucks the voice coil motor 6 onto the material picking head 412. The air pump is used to grab the voice coil motor 6, and finally the voice coil motor 6 is transferred from the feed tray 112 to the transfer tray 31.

[0055] The second gripping mechanism 42 includes a second motion control assembly 421, a sixth drive assembly, and a mounting head 422. The second motion control assembly 421 is mounted on the frame 1, and the mounting head 422 is mounted on the second motion control assembly 421. In this embodiment, the second motion control assembly 421 is a robotic arm that controls the movement of the mounting head 422 in the X, Y, and Z directions (the X, Y, and Z axes are perpendicular to each other). The second motion control assembly 421 controls the mounting head 422 to grasp the voice coil motor 6 on the transfer mechanism 3 and mount it on the FPC module 5. The sixth drive assembly comprises a servo motor and a lead screw. The servo motor is mounted in the frame 1 and connected to the lead screw. The servo motor drives the lead screw to rotate, which is connected to the robotic arm and controls the movement of the robotic arm between the transfer mechanism 3 and the FPC module 5. Controlled by the second motion control assembly 421 and the sixth drive assembly, the mounting head 422 moves between the transfer mechanism 3 and the second feeding mechanism 12.

[0056] In this embodiment, the mounting head 422 is made of rubber and is connected to an air pump (not shown) via a pipe. The air pump is installed within the frame 1. The air pump generates negative pressure on the mounting head 422, which draws the voice coil motor 6 onto the mounting head 422, thereby grasping the voice coil motor 6. The sixth drive assembly drives the second motion control assembly 421 to move along the transfer mechanism 3 and the second feeding mechanism 12. The mounting head 422 secures the voice coil motor 6 through suction, ultimately affixing the voice coil motor 6 to the FPC module 5.

[0057] The feeding device for lens assembly according to an embodiment of the present application operates as follows: A first feeding mechanism 11 and a second feeding mechanism 12 respectively transfer a voice coil motor 6 and an FPC module 5 to a transfer mechanism 3. This transfer improves material transfer efficiency. After the voice coil motor 6 is transferred to one side of a transfer tray 31, a first gripping mechanism 41 grips the voice coil motor 6 onto the transfer tray 31. A fixing assembly 33 on the transfer tray 31 grips and secures the voice coil motor 6, minimizing the risk of the voice coil motor 6 striking the sidewalls of the placement slot 311 during initial rotation, potentially causing material damage.

[0058] The voice coil motor 6 begins rotating on the turntable 31, with the fixing assembly 33 always in place. When the voice coil motor 6 reaches the side of the FPC module 5, the turntable 31 pauses, releasing the fixing assembly 33 from its position. The second gripping mechanism 42 then grabs the voice coil motor 6 and installs it on the FPC module 5. The turntable 31 eliminates the need to transport the first and second gripping mechanisms 41, 42, and allows for simultaneous transport and installation, improving the efficiency of voice coil motor 6 installation.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
