[0022] The first connection area is a specific area on lens A used for connection with circuit board B, and it has screw holes and a protective film. The second connection area is a specific area on circuit board B used for connection with lens A, and it has screw holes and a protective film.

[0023] The main function of the fixture flow line 21 is to support the fixture C and drive it to pass sequentially through the first assembly loading station 211, the second assembly loading station 212, and the assembly station 213 along a predetermined path to complete the step-by-step assembly process of lens A and circuit board B. The fixture lifting mechanism 22 is used to lift the fixture C at the designated first assembly loading station 211, second assembly loading station 212, and assembly station 213, so that it is separated from the fixture flow line, achieving precise positioning of the fixture and facilitating subsequent loading, assembly, and other operations.

[0024] Lens feeding unit 3 corresponds to lens A and its function is to transport lens A in an orderly manner to the corresponding picking station, providing lens A for subsequent transfer operations. First gripping and transfer unit 4 is responsible for transferring lens A. Lens translation unit 5 and first tape tearing unit 6 work together to remove the protective film on the first connection area of ​​lens A; Circuit board feeding unit 7 corresponds to circuit board B and its function is to orderly transport circuit board B to the corresponding picking station, providing circuit board B for subsequent transfer operations. The second gripping and transferring unit 8 is responsible for transferring circuit board B and, in conjunction with the second tape peeling unit 9, removes the protective film from the second connection area of ​​circuit board B.

[0026] The working process of the camera assembly equipment of the present invention is described below, including the lens transfer process, the circuit board transfer process, and the screw tightening process: The lens transfer process includes the following steps: S11, the fixture streamline 21 drives the fixture C to the first assembly loading station 211, and the fixture lifting mechanism 22 lifts and positions the fixture C. S12, the lens feeding unit 3 transports the lens A to the first picking station. At this time, the first connecting area of ​​the lens A faces upward. The first gripping and transferring unit 4 grips the lens A and transfers it to the lens translation unit 5. At this time, the first connecting area of ​​the lens A faces upward. The lens translation unit 5 drives the lens A to translate to the area below the first film peeling station. At this time, the first connecting area of ​​the lens A faces upward. The first tape peeling unit 6 picks up the protective film of the lens A at the first film peeling station. S13. The first gripping and transfer unit 4 transfers the lens A after the film is peeled off to the fixture C of the first assembly and loading station 211 for positioning. At this time, the first connection area of ​​the lens A faces upward. S14, the jig lifting mechanism 22 descends, and the jig streamline 21 drives the jig C equipped with lens A to the second assembly loading station 212. At this time, the first connection area of ​​lens A faces upward.

[0027] The circuit board transfer process includes the following steps: S21, the fixture streamline 21 drives the fixture C equipped with lens A to the second assembly loading station 212, and the fixture lifting mechanism 22 lifts and positions the fixture C. S22. The circuit board feeding unit 7 transports the circuit board B to the second picking station. At this time, the second connection area of ​​the circuit board B is facing down. The second gripping and transfer unit 8 grips the circuit board B and transfers it to the second tape peeling unit 9. At this time, the second connection area of ​​the circuit board B is facing down. The second tape peeling unit 9 removes the protective film from the second connection area of ​​the circuit board B. The second gripping and transfer unit 8 transfers the peeled circuit board B to the circuit board positioning unit 10. At this time, the second connection area of ​​the circuit board B is facing down. The non-woven cloth wiping unit 11 cleans and wipes the second connection area of ​​the circuit board B. S23. The second gripping and transfer unit 8 transfers the wiped circuit board B to the fixture C of the second assembly and loading station 212. At this time, the second connection area of ​​the circuit board B faces downward and completes the initial loading with the already positioned lens A (without screws tightened). S24, the fixture lifting mechanism 22 descends, and the fixture streamline 21 drives the fixture C, which is equipped with lens A and circuit board B, to the assembly station 213.

[0028] The process of tightening screws includes the following steps: S31, the fixture flow line 21 drives the fixture C to the assembly station 213, and the fixture lifting mechanism 22 lifts and positions the fixture C. S32, the screw feeding unit 12 conveys the screws to the third picking station in an orderly manner; S33, the screw-tightening unit 13 picks up the screw, aligns it with the screw holes of lens A and circuit board B, and completes the screw-tightening operation to achieve mechanical fixation between lens A and circuit board B; S34, the fixture lifting mechanism 22 descends, and the fixture streamline 21 drives the assembled camera out.

[0029] The various steps can be performed simultaneously or sequentially as needed, as long as they do not affect the overall process flow.

[0030] Through the above technical solutions, firstly, the camera assembly equipment of the present invention integrates fully automated units for feeding, film removal, wiping, transfer, and screw tightening, eliminating the need for manual intervention in core assembly processes and significantly improving production efficiency. Secondly, the camera assembly equipment of the present invention effectively removes protective film and impurities from the connection area through dedicated film removal and wiping units, avoiding poor connections caused by foreign objects; mechanical screw tightening ensures consistent screw tightening force and improves product yield. Thirdly, the camera assembly equipment of the present invention adopts an assembly line design: a jig flow line drives the jig through three workstations sequentially, realizing step-by-step operations of lens loading, circuit board loading, and screw tightening, with each unit working in parallel, improving the overall utilization rate of the equipment.

[0031] In this embodiment, both the lens feeding unit 3 and the circuit board feeding unit 7 include a tray translation mechanism 31, a first tray lifting mechanism 32, a first suction cup mechanism 33, a second tray lifting mechanism 34, and a second suction cup mechanism 35. The aforementioned tray translation mechanism 31 includes a tray support plate 311 and a tray translation drive device 312. The tray support plate 311 is used to support the tray D. The tray translation drive device 312 is connected to the tray support plate 311 and is used to drive the tray support plate 311 to move between the first support plate station and the second support plate station. The first material tray lifting mechanism 32 is located below the first support plate station and is used to support the multi-layer material trays D and drive the uppermost material tray D to a first preset height. The first suction cup mechanism 33 is located above the first support plate station and is used to pick up the uppermost material tray on the first material tray lifting mechanism 32 and drive the material tray to fall onto the material tray support plate 311 of the first support plate station. The second material tray lifting mechanism 34 is located below the second support plate station and is used to support the multi-layer material trays and drive the uppermost material tray to a first preset height. The second suction cup mechanism 35 is located above the second support plate station and is used to pick up the material tray on the material tray support plate 311 of the second support plate station and drive the material tray to fall onto the second material tray lifting mechanism 34.

[0032] The first support plate station and the second support plate station are two preset stations of the tray translation mechanism 31. The first support plate station corresponds vertically to the first tray lifting mechanism 32 and the first suction cup mechanism 33, and is the transfer station for the tray D to be transferred from the storage area to the tray translation mechanism 31. The second support plate station corresponds vertically to the second tray lifting mechanism 34 and the second suction cup mechanism 35, and is the transfer station for the tray D to be transferred from the tray translation mechanism 31 to another storage area. The first preset height is the preset positioning height of the tray handling unit, which is the height to which the uppermost tray D is driven by the first tray lifting mechanism 32 and the second tray lifting mechanism 34. This height matches the suction height of the first suction cup mechanism 33 and the second suction cup mechanism 35, ensuring that the first suction cup mechanism 33 and the second suction cup mechanism 35 can accurately and stably suck up the tray D.

[0033] The tray support plate 311 is a load-bearing component used to directly support the tray D, providing a stable load-bearing foundation for the translational movement of the tray D. The tray translation drive device 312 is a power component used to drive the tray support plate 311 to move between two preset support plate positions, controlling the transfer path and position of the tray.

[0034] The first tray lifting mechanism 32 and the second tray lifting mechanism 34 are layered storage and height positioning components for the tray D. They can support multiple trays D and lift the uppermost tray D to a first preset height, so that the first suction cup mechanism 33 and the second suction cup mechanism 35 can accurately pick it up.

[0035] The first suction cup mechanism 33 and the second suction cup mechanism 35 are vertical transfer execution components for the material tray D. They pick up the material tray D through negative pressure adsorption, thereby realizing the vertical transfer of the material tray D between the first material tray lifting mechanism 32, the material tray support plate 311, and the second material tray lifting mechanism 34.

[0036] The following describes the process of handling the material tray, including the following steps: S41, the material tray support plate 311 leaves the first support plate station, the first suction cup mechanism 33 descends, and sucks up the uppermost full material tray D on the first material tray lifting mechanism 32; S42, the first suction cup mechanism 33 rises and moves, raising the full material tray D to a height higher than the material tray support plate 311. The first material tray lifting mechanism 32 drives the remaining material tray to rise, repositioning the new uppermost material tray to the first preset height, waiting for the next suction. S43, the tray support plate 311 returns to the first support plate station; S44, The first suction cup mechanism 33 places the full material tray D it has picked up onto the material tray support plate 311; S45, After the material in the tray on the tray support plate 311 is removed; S46, the material tray support plate 311 drives the perforated material tray D to the second support plate station; S47. The first suction cup mechanism 33 descends to suck up the empty material tray D on the material tray support plate 311; S48. The first suction cup mechanism 33 rises and moves, raising the empty material tray D to a height higher than the material tray support plate 311. S49, the tray support plate 311 leaves the second support plate station; S49. The second suction cup mechanism 35 places the sucked empty material tray D on the second material tray lifting mechanism 34. The second material tray lifting mechanism 34 drives all material trays to descend, repositioning the new uppermost material tray to the first preset height, waiting for the next material tray to be received, thus completing the handling of one material tray.

[0037] Through the above technical solution, firstly, the two sets of material tray lifting mechanisms enable layered storage of full material trays and layered recycling of empty material trays, eliminating the need for frequent manual loading and unloading and significantly improving the continuous operation capability of the equipment; secondly, the material tray translation mechanism, in conjunction with the suction cup mechanism, enables horizontal and vertical coordinated transfer of material trays between two workstations, with high positioning accuracy and stable transfer efficiency; thirdly, the loading of full material trays and the recycling of empty material trays are completed through independent lifting and suction cup mechanisms, enabling parallel operation, avoiding process waiting, and improving the overall efficiency of material tray handling.

[0038] In this embodiment, the lens feeding unit 3 further includes a tray separating mechanism 36, which is used to insert into the bottom of the tray located at the first preset height.

[0039] The core function of the tray separating mechanism 36 is to insert into the bottom of the tray D located at the first preset height, thereby physically separating the top tray from the stacked trays below. This prevents the lower trays from being lifted up by the suction cup mechanism when it picks up the top tray due to the adsorption force or frictional resistance between the trays, ensuring the accuracy and stability of tray picking.

[0040] In step S41, before the first suction cup mechanism 33 descends to pick up the uppermost full material tray D, the tray separating mechanism 36 first inserts between the uppermost material tray D and the next uppermost material tray D, and then the first suction cup mechanism 33 picks up the material tray D.

[0041] The above technical solution eliminates the adsorption and friction between the material trays through physical separation, completely solving the problem of multiple material trays being lifted together when stacked, ensuring that the suction cup mechanism picks up only one material tray at a time, and avoiding material feeding chaos and material damage caused by the simultaneous transfer of multiple material trays.

[0042] In this embodiment, the first gripping and transfer unit 4 includes a lens gripper 41, a wire gripper 42, and a first robotic arm 43. The lens gripper 41 is used to hold the base of the lens, the wire gripper 42 is used to hold the wire of the lens, and the first robotic arm 43 connects the lens gripper 41 and the wire gripper 42 to drive the lens gripper 41 and the wire gripper 42 to perform spatial movement.

[0043] Among them, the first gripping and transfer unit 4 achieves stable gripping and transfer of the lens through the coordinated operation of the two grippers.

[0044] The lens gripper 41 is the main gripping component of the first gripping and transfer unit 4. It is specifically designed to grip the base of the lens A, providing a stable and rigid gripping force to ensure that the lens body does not shift or shake during transport.

[0045] The wire clamp 42 is an auxiliary clamping component of the first gripping and transfer unit 4. It is specifically used to clamp the wire of lens A, which can prevent the wire from being damaged by pulling or tangling during transportation and ensure the integrity of the electrical connection of the lens.

[0046] The first robotic arm 43 is the power and motion execution component of the first gripping and transfer unit 4. It connects the lens gripper 41 and the wire gripper 42 and is used to drive the two grippers to perform multi-degree-of-freedom spatial motion, so as to realize the precise transfer of the lens between different work positions and different heights.

[0047] The lens-grabbing process of the first transfer unit includes the following steps: S51, Initial state of the grippers: Both the lens gripper 41 and the wire gripper 42 are in the open state. The first robotic arm 43 drives the two grippers to move to the material picking position above the material tray. S52, the first robotic arm 43 adjusts its posture so that the lens gripper 41 is aligned with the base of the lens A in the tray and the wire gripper 42 is aligned with the wire of the lens. S53, the lens clamp 41 closes to hold the base of lens A; simultaneously, the wire clamp 42 closes to hold the wire of lens A, completing the dual-clamp coordinated clamping.

[0048] S54, the first robotic arm 43 drives the double grippers and lens A to rise, detach from the material tray, and complete the material picking.

[0049] S55, the first robotic arm 43 drives the double grippers and lens A to move above the lens positioning plate 511 at the film-tearing and loading station, aligning with the idle elastic clamping structure 513.

[0050] S56, the lens clamp 41 and the wire clamp 42 open simultaneously, placing the new lens A in the idle clamping structure to complete the lens loading.

[0051] S57, the first robotic arm 43 adjusts its posture and moves the double grippers to the top of another elastic clamping structure 513 of the lens positioning plate 511 (equipped with a lens with the film already peeled off).

[0052] S58, the lens clamp 41 closes to hold the base of the lens with the coating removed; the wire clamp 42 closes to hold the wire of the lens with the coating removed, thus completing the clamping of the lens with the coating removed.

[0054] S510, the first robotic arm 43 drives the double grippers and the peeled lens to move to the fixture C above the first assembly and loading station, and aligns it with the lens positioning position inside the fixture.

[0056] S512, the first robotic arm 43 drives the double grippers to reset.

[0057] The above technical solution, through the dual fixing method of lens clamp holding the base and wire clamp holding the wire, completely avoids the positional displacement of the lens due to shaking and rotation during spatial transportation, while preventing the wire from separating from the lens body and ensuring the structural integrity of the lens.

[0058] In this embodiment, the lens translation unit 5 includes: The lens translation mechanism 51 includes a lens positioning plate 511 and a lens translation drive device 512. The lens positioning plate 511 is provided with two elastic clamping structures 513 for positioning the lens. The two elastic clamping structures 513 can simultaneously position two lenses. The lens translation drive device 512 is used to drive the lens positioning plate 511 to translate between the film-tearing and feeding station and the first film-tearing station. The side-pushing mechanism 52 is located on the side of the above-mentioned film-tearing and feeding station and is used to push the above-mentioned elastic clamping structure 513 to open.

[0059] The film-peeling and loading station is the work position where the first gripping and transferring unit 4 places lens A onto the lens positioning plate. The film-peeling station is the core position where the first tape-peeling unit 6 performs the film-peeling operation. The lens positioning plate 511 is a bearing and positioning component, equipped with a clamping structure that matches the shape of lens A. It is used to receive lens A from the first gripping and transferring unit 4 at the film-peeling and loading station and to ensure the positional accuracy of the lens during translation and film-peeling processes. The lens translation drive device 512 is a power component used to drive the lens positioning plate 511 to make linear reciprocating motion between the film-peeling and loading station and the film-peeling station, controlling the switching of the lens's work position.

[0060] The shape and size of each elastic clamping structure 513 are matched with the shape of the lens A, and are used to precisely limit and fix the individual lens A to ensure that the lens does not shift position during translation and film peeling.

[0061] Through the above technical solution, the two clamping structures on the lens positioning plate, one for placing and the other for taking off, reduce the waiting time for the lens coating to be removed and improve the efficiency of lens loading.

[0062] In this embodiment, the first tape tearing unit 6 includes: The first tape conveying mechanism 61 is used to unwind and rewind the tape and guide the tape above the first film-tearing station. The first tape ejection mechanism 62 is used to eject the tape above the first film-tearing station downwards.

[0063] The first tape peeling unit 6 achieves precise peeling of the protective film by using tape adhesion.

[0064] The first tape conveying mechanism 61 is a tape supply and recycling component, used to unwind and rewind the tape E, and guide the tape E to pass stably above the film peeling station through the guiding structure, providing a carrier for the adhesive peeling protective film.

[0065] The first tape ejection mechanism 62 is the core execution component of the first tape tearing unit 6. It is used to push the tape E that has passed above the tearing station downwards so that the tape can come into close contact with and adhere to the protective film surface of the first connection area of ​​the lens A.

[0066] The lens coating removal process includes the following steps: S61, the lens positioning plate 511 is in the film-tearing and feeding station, the adhesive surface of the tape E located in the film-tearing station on the first tape conveying mechanism 61 is facing down and no protective film is attached, the first tape ejection mechanism 62 is in the retracted state, the first gripping and transfer unit 4 transfers the lens A from the material tray to the lens positioning plate 511 in the film-tearing and feeding station, the first connecting area (with protective film) of the lens A is placed facing up and the positioning is completed. S62, the lens translation drive device 512 is started, driving the lens positioning plate 511 and lens A to translate from the film-peeling loading station to the film-peeling station. At this time, the protective film of lens A is directly below the tape E. After the first gripping and transfer unit 4 transfers lens A from the material tray to one of the elastic clamping structures 513 of the lens positioning plate 511 at the film-peeling loading station, the first gripping and transfer unit 4 transfers the film-peeled lens in the other elastic clamping structure 513 of the lens positioning plate 511 to the fixture C at the first assembly loading station. S63, the first tape ejection mechanism 62 is activated, pressing the tape E that has passed above the film tearing station downwards, so that the adhesive side of the tape is in close contact with and adheres to the protective film surface of the first connection area of ​​the lens A. S64, the first tape conveying mechanism 61 winds up the tape E, driving the tape segment with the protective film attached to it to move in the winding direction, while the lens translation mechanism remains stationary, and the protective film is completely peeled off from the first connection area of ​​the lens A by the pulling force of the tape movement. S65, the first tape ejection mechanism 62 retracts, releasing the pressure on tape E; S66, The lens translation drive device 512 is started, which drives the lens positioning plate 511 and the lens A after film peeling back from the film peeling station to the film peeling and loading station. S67. The first gripping and transferring unit 4 picks up the lens A with the film already peeled off from the lens positioning plate 511 and transfers it to the fixture C at the first assembly loading station, completing the material flow of the film peeling process. The lens positioning plate 511 remains at the film peeling loading station, waiting to receive the next lens A.

[0067] Through the above technical solution, firstly, the precise positioning of the lens positioning plate and the uniform speed movement of the tape conveyor mechanism achieve smooth peeling of the protective film, avoiding problems such as scratches on the lens connection area and protective film residue caused by manual tearing or direct mechanical tearing; secondly, the tape conveyor mechanism adopts an unwinding-rewinding cycle mode, which, together with the station switching of the lens translation mechanism, enables continuous loading, tearing, and unloading of lenses without waiting for tape replacement, thus improving the efficiency of the tearing process; thirdly, the peeled protective film is wound up together with the tape, facilitating subsequent centralized processing and preventing protective film fragments from scattering and causing equipment jamming or material contamination.

[0068] In this embodiment, the second gripping and transfer unit 8 includes a circuit board gripper 81 and a second robotic arm 82. The circuit board gripper 81 is used to grip the circuit board B, and the second robotic arm 82 is connected to the circuit board gripper 81 and is used to drive the circuit board gripper 81 to perform spatial movement.

[0069] Among them, the circuit board gripper 81 is a clamping component, which is specifically used to clamp the circuit board B. Its gripper structure matches the shape and thickness of the circuit board, and can provide a stable and gentle clamping force to avoid damaging the electronic components on the circuit board.

[0070] The second robotic arm 82 is a power and motion execution component, connected to the circuit board gripper, used to drive the circuit board gripper to perform multi-degree-of-freedom spatial motion, so as to realize the precise transfer and attitude adjustment of the circuit board between different work positions, different heights and different postures.

[0071] The circuit board gripping process of the second gripping and transfer unit includes the following steps: S71. In the initial state, the circuit board gripper 81 is in the open state. The second robotic arm 82 drives the gripper to move to the material tray D of the circuit board loading station and aligns it with the circuit board B in the material tray. S72, the second robotic arm 82 adjusts its posture so that the circuit board gripper 81 is aligned with the non-component area of ​​the circuit board B in the tray (to avoid damaging the components). S73, the circuit board gripper 81 closes, clamping circuit board B, completing the material removal; S74, the second robotic arm 82 drives the gripper and circuit board B to rise, detach from the tray, adjust the posture of the circuit board so that the second connection area (with protective film) faces down, and move to the second film-removing station. S75, the second robotic arm 82 drives the circuit board B to hover above the second film-tearing station, so that the second connection area is aligned with the tape E below; S76. Keep the circuit board clamping claw 81 in a clamping state, and cooperate with the second film peeling unit to complete the adhesive and peeling operation of the protective film (tape ejection, peeling mechanism assistance, tape rewinding). S77. After the film is peeled off, the second robotic arm 82 lifts the peeled circuit board B, removes it from the second film peeling station, adjusts its posture, and moves it above the circuit board support mechanism 101 of the wiping unit. S78, the second robotic arm 82 lowers the circuit board B and places it on the circuit board support mechanism 101 of the wiping unit, ensuring that the second connection area at the bottom of the circuit board is fully exposed; S79, the circuit board gripper 81 opens and releases the gripper, and the second robotic arm 82 drives the gripper to a safe area to wait for the wiping operation to be completed; S710 After the wiping unit completes the cleaning operation, the second robotic arm 82 drives the gripper back above the circuit board support mechanism 101, the circuit board gripper 81 closes, and re-grips the cleaned circuit board B. S711, the second robotic arm 82 drives the circuit board B to rise, detach from the wiping unit, and move to above the fixture C of the second assembly and loading station; S712, the second robotic arm 82 adjusts the posture of the circuit board so that the circuit board B is precisely aligned with the clamping structure on the fixture C, while ensuring that the circuit board corresponds to the connection area of ​​the lens A that has been placed on the fixture. S713, the circuit board gripper 81 opens, and the cleaned circuit board B is placed on the fixture C, completing the initial loading with the lens A; S714, the second robotic arm 82 drives the gripper to reset and return to the top of the material tray at the circuit board loading station, waiting for the next material picking and transfer operation.

[0072] Through the above technical solution, the circuit board can be continuously transferred between four different workstations by using the multi-degree-of-freedom spatial movement of the second robotic arm. The operation cycle is compact and can be seamlessly connected with the operation process of the second film-peeling unit and the wiping unit, thereby improving the overall assembly efficiency.

[0073] In this embodiment, the second tape tearing unit 9 includes: The second tape conveying mechanism 91 is used to unwind and rewind the tape and guide the tape below the second film-tearing station. The second tape ejection mechanism 92 is used to eject the tape below the second film tearing station upwards; The peeling rod mechanism 93 is used to translate above the second film-tearing station.

[0074] The second tape peeling unit 9 achieves precise peeling of the circuit board protective film through a combination of tape adhesion and mechanically assisted peeling. The second peeling station is the core position where the second tape peeling unit 9 performs the peeling operation. It precisely corresponds to the movement positions of the second tape conveying mechanism 91, the second tape ejection mechanism 92, and the peeling rod mechanism 93, and is the working area for peeling the circuit board protective film.

[0075] The second tape conveying mechanism 91 is a tape supply and recycling component, used to unwind and rewind the tape E, and guide the tape below the second film-tearing station with the adhesive side facing up, providing a carrier for bonding the circuit board protective film.

[0076] The second tape ejection mechanism 92 is an adhesive actuation component used to eject the tape E below the second film-tearing station upwards, so that the adhesive side of the tape comes into close contact with and adheres to the protective film of the second connection area of ​​the circuit board B.

[0077] The peeling rod mechanism 93 is a mechanically assisted peeling component used to move horizontally above the second film peeling station. Through pushing or scraping actions, the auxiliary tape E completely peels the protective film from the second connection area of ​​the circuit board B, solving the problem of the protective film sticking too tightly to the circuit board.

[0078] The circuit board film removal process includes the following steps: S81. The adhesive side of the tape E that has passed through the second film-tearing station is facing up and there is no adhesive protective film. The second tape ejection mechanism 92 is in the retracted state, the peeling bar mechanism 93 is in the initial translation position above the second film-tearing station, and the second gripping and transfer unit 8 transfers the circuit board B from the tray to the second film-tearing station and makes the second connection area (with protective film) of the circuit board face down, aligned with the tape E below. S82, the second tape ejection mechanism 92 is activated, ejecting tape E upwards, so that the adhesive side of the tape is in close contact with and adheres to the protective film of the second connection area of ​​the circuit board B, ensuring that the adhesive force between the protective film and the tape is greater than the adhesion force between the protective film and the circuit board. S83, the second tape ejection mechanism 92 resets. The tape descends, creating an opening between the second connection area of ​​circuit board B and the protective film. The peeling rod mechanism 93 is activated simultaneously, entering between the second connection area of ​​circuit board B and the protective film through the opening, assisting the tape in completing the peeling of the protective film. S84. The peeled protective film is wound up and recycled together with the tape by the second tape conveyor mechanism 91.

[0079] The above technical solution, through the structural design of the tape being placed at the bottom and pushed upward, is adapted to the working posture of the circuit board protective film facing downward, avoiding collisions or scratches between other electronic components and equipment parts on the circuit board. The mechanically assisted translational action of the peeling rod mechanism can effectively solve the problem of incomplete peeling of the circuit board protective film caused by excessive adhesion or excessive adhesion to the circuit board, ensuring complete peeling of the protective film without residue.

[0080] In this embodiment, the circuit board positioning unit 10 includes: The circuit board support mechanism 101 is located above the wiping station and is used to support the circuit board, expose the second connection area at the bottom of the circuit board, and drive the second connection area of ​​the circuit board to move closer to and away from the wiping station in the vertical direction. The circuit board pressing mechanism 102 is located above the wiping station and is used to press the circuit board on the circuit board support mechanism.

[0081] The circuit board support mechanism 101 is a circuit board bearing and positioning component, located above the wiping station. It supports the circuit board B, exposes the second connection area at its bottom, and drives the circuit board B to move closer to / away from the wiping station in the vertical direction, controlling the contact and separation between the wiping strip and the connection area.

[0082] The circuit board clamping mechanism 102 is a circuit board fixing component used to clamp the circuit board B on the circuit board support mechanism 101 to prevent the circuit board B from shifting or shaking during the wiping process and to ensure wiping accuracy.

[0083] In this embodiment, the nonwoven fabric wiping unit 11 includes: The wiping belt conveyor 111 is used to unwind and rewind the wiping belt, guide the wiping belt through the above-mentioned wiping station, and drive the wiping belt to reciprocate along its length. The spraying mechanism 113 is used to spray cleaning fluid onto the wiping belt that passes through the wiping station.

[0084] The non-woven fabric wiping unit 11 achieves high-precision cleaning of the circuit board connection area through "cleaning liquid spraying + reciprocating wiping with a wiping belt". Wiping station: The core position for the wiping unit to perform cleaning operations is the coordinated action area of ​​the wiping belt F, the positioning mechanism, and the liquid spraying mechanism. The second connection area of ​​the circuit board is cleaned here.

[0085] The wiping belt conveyor 111 is a cleaning carrier supply and recycling component, used to unwind and rewind the wiping belt F, and guide the wiping belt to pass stably through the wiping station, providing a clean wiping medium for cleaning operations.

[0086] The wiping belt translation mechanism 112 is a wiping trajectory driving component, which drives the wiping belt conveyor 111 to reciprocate along the length direction of the wiping belt F, so that the wiping belt and the circuit board connection area generate relative movement to achieve full wiping.

[0087] The spraying mechanism 113 is a cleaning fluid supply component, used to spray cleaning fluid onto the wiping belt F passing through the wiping station, thereby improving the cleaning effect on impurities in the connection area through the dissolving effect of the cleaning fluid.

[0088] The circuit board wiping process includes the following steps: S91, the wiping belt conveyor 111 is started, driving the wiping belt F to circulate at low speed. New wiping belt segments continuously enter the wiping station. The wiping belt translation mechanism 112 drives the wiping belt conveyor 111 to the initial position of reciprocating motion. The circuit board support mechanism 101 is in a high position (the circuit board is separated from the wiping belt). The circuit board pressing mechanism 102 is in a loose state. The spraying mechanism 113 is started, continuously spraying cleaning liquid onto the wiping belt F passing through the wiping station to keep the wiping belt moist. S92, the second gripping and transfer unit 8 transfers the circuit board B after the film is peeled off to the circuit board support mechanism 101 above the wiping station. The second connection area at the bottom of the circuit board B is set downwards. The circuit board support mechanism 101 accurately supports the circuit board B and exposes the second connection area. S93, the circuit board clamping mechanism 102 is activated, pressing down on the circuit board B on the circuit board support mechanism 101 to complete the fixing of the circuit board; S94. The circuit board support mechanism 101 drives the fixed circuit board B to descend vertically, so that the second connection area at the bottom of the circuit board B approaches and adheres to the wet wiping strip F on the wiping station.

[0089] S95, the wiping belt translation mechanism 112 is started, driving the wiping belt conveyor mechanism 111 to reciprocate along the length of the wiping belt F, so as to achieve a comprehensive and thorough wiping of the second connection area of ​​the circuit board B; S96. After completing the preset number of wiping cycles, the wiping belt translation mechanism 112 drives the wiping belt conveyor mechanism 111 back to the initial position, and the circuit board support mechanism 101 drives the circuit board B to rise in the vertical direction, so that the second connection area is away from the wiping belt F and returns to the high position. S97. The circuit board clamping mechanism 102 is released, thus releasing the fixation of the circuit board B. S98, the second gripping and transfer unit 8 picks up the cleaned circuit board B from the positioning mechanism and transfers it to the fixture C at the second assembly and loading station, completing the material flow of the wiping process.

[0090] The wiping belt conveyor 111 rewinds the used wiping belt, and a new wiping belt segment enters the wiping station, waiting for the next circuit board cleaning operation.

[0091] Through the above technical solution, on the one hand, the composite cleaning method of "cleaning liquid spraying + wiping belt circulation + translational reciprocating motion" can more efficiently dissolve and remove dust, adhesive residue and other impurities in the circuit board connection area compared with a single wiping method, ensuring the reliability of subsequent screw connections; on the other hand, the circulating winding design of the wiping belt conveyor mechanism ensures that the used dirty wiping belt is recycled in time, and new wiping belt segments continuously enter the wiping station, avoiding secondary contamination of the circuit board connection area by impurities.

[0092] In this embodiment, the screw-tightening unit 13 includes: The elastic pressure plate mechanism 131 is used to elastically press the upper surface of the circuit board in the fixture at the assembly station; The screw-tightening mechanism 132 is used to screw the screws into the screw holes of the lens and the circuit board in sequence. NG gripper 133 is used to remove circuit boards and lenses that cannot be screwed on. The three-axis motion mechanism 134 connects the aforementioned elastic pressure plate mechanism, screw tightening mechanism, and NG product gripper, driving the aforementioned elastic pressure plate mechanism, screw tightening mechanism, and NG product gripper to perform spatial movement.

[0093] Among them, the screw-tightening unit 13 integrates the full-process functions of "pressing and positioning - screw-tightening and fixing - NG product sorting", realizing the automation of assembly and yield control.

[0094] The elastic pressure plate mechanism 131 is a positioning auxiliary component used to elastically press the upper surface of the circuit board B in the assembly station fixture C. It ensures that the connection area between the lens A and the circuit board B is tightly fitted and the screw holes are accurately aligned through flexible pressure, while avoiding damage to the circuit board components by rigid pressing.

[0095] The screw-tightening mechanism 132 is an actuator used to screw the screws into the screw holes of the lens and the circuit board in sequence to complete the mechanical fixation of the two. It usually integrates functions such as screw picking, alignment, and tightening torque control.

[0096] The NG (Not Good) gripper 133 is a defective product sorting component in the screw-tightening unit. It is used to transfer circuit boards and lenses that failed to be screwed on (such as stripped screws, loose screws, misalignment, etc.) away from the fixture, thus achieving automatic separation of good and defective products. NG products refer to assemblies that did not meet quality requirements during the screw-tightening process, including products with loose screws, stripped screws, misalignment, or poor lens-circuit board fit.

[0097] The three-axis motion mechanism 134 is a power and positioning component, connecting the elastic pressure plate mechanism 131, the screw tightening mechanism 132, and the NG product gripper 133. It is used to drive the three components to perform X / Y / Z three-axis spatial motion, so as to realize the precise alignment and action switching of each component above the fixture.

[0098] The process of connecting the lens to the circuit board by screwing in the following steps: S101, Fixture C drives the combined lens A and circuit board B to the assembly station 213. Fixture lifting mechanism 22 lifts the fixture and positions it precisely. Screw feeding unit 12 transports screws to screw loading station in an orderly manner, waiting for screw tightening mechanism to pick them up. Three-axis motion mechanism 134 drives elastic pressure plate mechanism 131, screw tightening mechanism 132, and NG product gripper 133 to a safe waiting position.

[0099] S102, the three-axis motion mechanism drives the screw tightening mechanism 132 to move to the screw feeding station and pick up the screw to be tightened; S103, the three-axis motion mechanism 134 drives the elastic pressure plate mechanism 131 to move above the fixture, aligning it with the non-component area on the upper surface of the circuit board B. The elastic pressure plate mechanism moves downward through its own drive mechanism, so that it elastically presses against the upper surface of the circuit board, ensuring that the lens and the screw holes of the circuit board are completely aligned and fit tightly without gaps.

[0100] S104, the three-axis motion mechanism 134 drives the screw-tightening mechanism 132, which holds the screw, to move downward, align the screw with the screw hole and perform the tightening action, and screw in all the screws in sequence. At the same time, the torque control ensures that the screw tightening force meets the requirements.

[0101] After all screws are tightened, the equipment inspection unit (preset) inspects the quality of the screw tightening (e.g., whether the torque meets the standard, whether the screw is in place). If the inspection is qualified, the three-axis motion mechanism 134 drives the elastic pressure plate mechanism 131 to reset upwards, releasing the pressure on the circuit board; the fixture lifting mechanism 22 descends, and the fixture streamline 21 carries the assembled good camera components out of the assembly station. If the inspection is unqualified (e.g., screws are stripped or not tightened), the three-axis motion mechanism 134 first drives the elastic pressure plate mechanism 131 to reset, and then drives the NG product gripper 133 to move above the fixture, clamping the circuit board and lens that were not tightened successfully. The three-axis motion mechanism drives the NG product gripper and defective products to the preset NG product placement area, releasing the defective products to complete the sorting; then drives the NG product gripper to reset, waiting for the next group of products to be processed. The reset cycle is repeated as the three-axis motion mechanism 134 drives all components back to the safe waiting position, waiting for the next fixture to arrive at the assembly station, and repeats the above process.

[0102] Through the above technical solutions, on the one hand, the flexible clamping design of the elastic pressure plate mechanism ensures the precise alignment of the lens and the screw holes of the circuit board, while avoiding damage to the circuit board components by rigid pressure, and ensuring the tight fit of the two after assembly. On the other hand, the screw tightening mechanism integrates torque control function, which can ensure that the tightening force of each screw is consistent, avoid product failure caused by being too loose or too tight, and improve the stability of assembly quality.

[0103] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
