Description

Technical Field

[0001] This invention relates to an automatic assembly machine, and more particularly to a fully automatic assembly machine for an integrated vehicle lens, applicable to the field of assembly machine technology. Background Technology

[0002] Automotive cameras are indispensable "visual" components for modern intelligent vehicles to perceive their external and internal environments. They are technologically advanced, have stringent requirements, and are used in a wide range of scenarios. Furthermore, with the increasing intelligence of automobiles, their performance, quantity, and role are all growing rapidly. They are one of the key foundations for achieving a safer, more convenient, and smarter driving experience. The assembly process for automotive cameras is becoming increasingly demanding, requiring precise assembly of lens components such as lenses, spacers, and seals.

[0003] Chinese patent CN219189274U discloses an automatic assembly equipment for vehicle-mounted lens modules. This automatic assembly equipment realizes automated feeding, assembly, and screw fastening of workpieces, improving production efficiency and processing quality while reducing manual input. Through the combination of vision camera and assembly parts, precise positioning and assembly fastening can be achieved, improving assembly accuracy. Chinese patent CN218874333U discloses a composite assembly machine for vehicle-mounted lenses, which is also equipped with a correction unit, a lower camera imaging unit, and an upper camera imaging unit. The correction unit includes two sets, which are respectively installed on one side of the two sets of discharge positioning units. The correction unit is used to mechanically correct the lens parts picked up by the double-moving assembly gantry unit.

[0004] In the current assembly process of automotive lenses, visual monitoring is used to calibrate each component to improve the assembly accuracy. However, when a component shifts, it needs to be corrected. The traditional correction method is clamping correction, which uses a clamp with the same external shape as the component. However, this method requires the component to be stopped, and each component requires a different correction clamp, thus affecting the assembly efficiency of the automotive lens. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the clamping and correction method requires the vehicle-mounted lens component to be stopped, and each type of vehicle-mounted lens component requires a different correction fixture, which affects the assembly efficiency of the vehicle-mounted lens.

[0006] To address the aforementioned issues, this invention provides a fully automatic vehicle-mounted lens assembly machine, comprising a machine body. Two feeding modules and two assembly modules are fixedly connected to the upper end of the machine body. The two feeding modules are located on opposite sides of the two assembly modules. A gantry frame is fixedly connected to the top of the machine body. Motion assembly modules are slidably connected to both ends of the middle section of the gantry frame. The motion assembly modules move between the feeding modules and the assembly modules. A motion photography positioning module is fixedly connected between the feeding modules and the assembly modules, with the camera end of the motion photography positioning module facing the bottom of the motion assembly module.

[0007] The bottom of the motion assembly module is fixedly connected to a rotating module. The output end of the rotating module is movably connected to a part suction pen. The bottom of the part suction pen is connected to a suction pen head. The bottom of the suction pen head is attached to a vehicle-mounted lens component, and the outer diameter of the suction pen head is the same as the outer diameter of the vehicle-mounted lens component.

[0008] The motion photography positioning module is externally fixedly connected to a calibration mechanism module, which includes an adjustment slide. One end of the adjustment slide is fixedly connected to a calibration cylinder, and the output end of the calibration cylinder is fixedly connected to a limiting guide bar that moves in opposite directions. The outside of the pen tip rolls in contact with the outer surface of the limiting guide bar.

[0009] In the aforementioned fully automatic assembly machine for vehicle-mounted lenses, the motion photography and positioning module performs image detection on the vehicle-mounted lens components extracted by the motion assembly module, and uses the correction mechanism module to correct the positional deviation of the vehicle-mounted lens components, effectively improving the assembly effect of the vehicle-mounted lenses.

[0010] As a further improvement of this application, a material feeding and photography positioning module is slidably connected to both ends of the top of the gantry, and an assembly photography positioning module is slidably connected to the middle of the gantry. The camera ends of the material feeding and photography positioning modules and the assembly photography positioning module are respectively facing the material feeding module and the assembly module. The material feeding and photography positioning modules are used to monitor the material feeding module and the assembly module, which effectively improves the accuracy of the vehicle-mounted lens assembly process.

[0011] As a further improvement of this application, the feeding photo positioning module, the assembly photo positioning module, and the motion photo positioning module are all composed of a photo moving module, a camera, a lens, and a light source. The camera, lens, and light source are fixedly installed on the outside of the photo moving module in sequence. The adjusting slide is fixedly connected to one end of the photo moving module. The camera, lens, and light source are arranged in a straight line in sequence to realize the center coordinate detection of the vehicle lens component, which facilitates the offset calibration of the vehicle lens component.

[0012] As a further improvement of this application, the two limiting guides are arranged in parallel to each other, and the limiting guides are made of stainless steel, which effectively improves the structural strength of the limiting guides. In addition, the surface of the limiting guides made of stainless steel is smooth, which effectively reduces the friction between the vehicle lens component and the limiting guides.

[0013] As a further improvement of this application, a component groove is formed on the bottom surface of the limiting guide strip. The component groove is lower than the bottom end of the suction pen tip, and the inner part of the component groove is fixedly connected with abutment protrusions at equal intervals. The outer end of the abutment protrusion is flush with the outer surface of the limiting guide strip, and the outer end of the abutment protrusion makes rolling contact with the outer ring of the vehicle lens component. When the suction pen tip rolls on the limiting guide strip with the vehicle lens component, the outer ring of the vehicle lens component is provided with correction support by the abutment protrusion. Furthermore, the contact area between the vehicle lens component and the limiting guide strip is effectively reduced by the abutment protrusion, which further effectively reduces the friction between the vehicle lens component and the limiting guide strip.

[0014] As a further improvement of this application, guide wheels are rotatably connected to both ends of the limiting guide strip, and a rotating belt is rotatably connected between the two guide wheels. The outer surface of the rotating belt makes rolling contact with the pen tip. By having the pen tip make rolling contact with the rotating belt, the friction between the vehicle lens component and the limiting guide strip is effectively reduced.

[0015] As a further improvement of this application, a shaping ring is fixedly connected to the middle of the rotating belt ring. The shaping ring is made of high-density polyethylene material, and the rotating belt ring is made of high molecular weight polyethylene material. The shaping ring effectively improves the structural strength of the rotating belt ring, facilitates the rotational movement of the rotating belt ring, and the rotating belt ring made of high molecular weight polyethylene material has excellent wear resistance, effectively improving the service life of the rotating belt ring.

[0016] As a further improvement of this application, a linkage toothed ring is fixedly connected to the outside of the shaping ring, and a linkage toothed groove is opened on the outside of the suction head. The linkage toothed ring and the linkage toothed groove are meshed and connected. By using the meshing transmission between the linkage toothed ring and the linkage toothed groove, the rotating belt ring can automatically follow the rotation of the suction head, effectively improving the self-rotation capability of the rotating belt ring.

[0017] In summary, this invention uses a motion-based imaging and positioning module to monitor the status of the vehicle-mounted lens components sucked up by the negative pressure of the motion assembly module. This effectively improves the assembly accuracy of the vehicle-mounted lens components. When a deviation in the status of the vehicle-mounted lens components is detected, a correction mechanism module is used to adjust the status of the vehicle-mounted lens components. The correction cylinder drives two limiting guides to close towards each other, so that the distance between the two limiting guides corresponds to the outer diameter of the suction pen head and the vehicle-mounted lens components. The limiting guides restrict the lateral movement of the suction pen head and the vehicle-mounted lens components. Then, the rotating module drives the component suction pen to rotate. The vehicle-mounted lens components that have deviated from the suction pen head are pushed back by the limiting guides, achieving centerline alignment between the vehicle-mounted lens components and the suction pen head. Compared with the traditional clamping correction method, the motion assembly module also maintains the movement state from the feeding module to the assembly module, effectively reducing the pause time for vehicle-mounted lens component deviation correction, thereby effectively improving the assembly efficiency of the vehicle-mounted lens components.

[0033] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] First implementation method:

[0035] Figure 1 and Figure 2The diagram illustrates a fully automatic assembly machine for an integrated vehicle-mounted lens, comprising a body 1. Two feeding modules 101 and two assembly modules 102 are fixedly connected to the upper end of the body 1. The feeding modules 101 are located on opposite sides of the assembly modules 102. The feeding modules 101 provide the components required for the vehicle-mounted lens, with each component placed in a different feeding tray according to its type. The feeding modules 101 provide the corresponding components according to the assembly stage of the vehicle-mounted lens. The assembly modules 102 provide an assembly platform for the vehicle-mounted lens, enabling the sequential assembly of different components. A gantry frame 103 is fixedly connected to the top of the body 1. Both ends of the middle part of 03 are slidably connected to motion assembly modules 2. The motion assembly modules 2 are movable between the feeding module 101 and the assembly module 102. The motion assembly modules 2 are used to transfer the parts on the feeding module 101 to the assembly module 102 and assemble the parts by pressing. A motion photography positioning module 104 is fixedly connected between the feeding module 101 and the assembly module 102. The camera end of the motion photography positioning module 104 faces the bottom of the motion assembly module 2. The motion photography positioning module 104 monitors the part transfer process of the motion assembly module 2, effectively improving the accuracy of the vehicle lens assembly process.

[0036] During the assembly process of the vehicle-mounted lens, the feeding module 101 places the components into the corresponding feeding trays according to their different types. During the assembly stage of the vehicle-mounted lens, the motion assembly module 2 uses the corresponding feeding trays to transfer the components provided by the feeding module 101 to the assembly module 102. Various components are pressed and assembled sequentially on the assembly module 102. During the assembly process, the motion imaging and positioning module 104 monitors the component transfer process of the motion assembly module 2, effectively improving the accuracy of the vehicle-mounted lens assembly process.

[0037] Figures 2 to 6As shown, a feeding camera positioning module 105 is slidably connected to both ends of the top of the gantry 103, and an assembly camera positioning module 106 is slidably connected to the middle of the gantry 103. The camera ends of the feeding camera positioning module 105 and the assembly camera positioning module 106 are respectively oriented towards the feeding module 101 and the assembly module 102. The feeding camera positioning module 105 and the assembly camera positioning module 106 are used to monitor the images of the feeding module 101 and the assembly module 102, effectively improving the accuracy of the vehicle-mounted lens assembly process. 05. The assembled photo positioning module 106 and motion photo positioning module 104 are both composed of a photo moving module 107, a camera 108, a lens 109 and a light source 110. The camera 108, lens 109 and light source 110 are fixedly set on the outside of the photo moving module 107 in sequence. The adjusting slide 301 is fixedly connected to one end of the photo moving module 107. The camera 108, lens 109 and light source 110 are arranged in a straight line in sequence to realize the center coordinate detection of the vehicle lens component 204, which facilitates the offset calibration of the vehicle lens component 204.

[0038] When the feeding module 101 and the assembly module 102 are working, the feeding photo positioning module 105 and the assembly photo positioning module 106 respectively take photos of the feeding module 101 and the assembly module 102, which further improves the accurate positioning of the components on the feeding module 101 and the assembly module 102, facilitates the precise motion control of the motion assembly module 2, further improves the accurate assembly of the vehicle lens, and effectively improves the assembly efficiency of the vehicle lens.

[0039] Figures 6 to 8 As shown, a rotating module 201 is fixedly connected to the bottom of the motion assembly module 2. The rotating module 201 is configured as a servo motor, capable of adjusting its direction and speed. A component suction pen 202 is movably inserted into the output end of the rotating module 201. A suction pen head 203 is inserted into the bottom of the component suction pen 202. A vehicle-mounted lens component 204 is adsorbed onto the bottom of the suction pen head 203. The vehicle-mounted lens component 204 includes a lens, a gasket, a sealing ring, and other components. The lens barrel is generally placed directly on the material tray of the assembly module 102, and the outer diameter of the suction pen head 203 is the same as the outer diameter of the vehicle-mounted lens component 204. The motion photography positioning module 104... The external fixed connection is a calibration mechanism module 3, which includes an adjustment slide 301. One end of the adjustment slide 301 is fixedly connected to a calibration cylinder 302. The output end of the calibration cylinder 302 is fixedly connected to a limiting guide bar 303 that moves in opposite directions. The outside of the pen tip 203 rolls in contact with the outer surface of the limiting guide bar 303. The two limiting guide bars 303 are arranged parallel to each other and are made of stainless steel, which effectively improves the structural strength of the limiting guide bar 303. In addition, the surface of the limiting guide bar 303 made of stainless steel is smooth, which effectively reduces the friction between the vehicle lens component 204 and the limiting guide bar 303.

[0040] The motion assembly module 2 uses a component suction pen 202 to perform negative pressure suction of the vehicle-mounted lens component 204. Different types of vehicle-mounted lens components 204 have corresponding suction pen heads 203. During the process of the motion assembly module 2 moving the vehicle-mounted lens component 204 from the feeding module 101 to the assembly module 102, the motion assembly module 2 passes above the motion imaging and positioning module 104 to monitor the status of the negative pressure suctioned vehicle-mounted lens component 204. When there is a deviation in the status of the vehicle-mounted lens component 204, the correction mechanism module 3 is used to correct the status of the vehicle-mounted lens component 204. The correction cylinder 302 drives the two limiting guide strips 303 to move closer together, so that the distance between the two limiting guide strips 303 and the suction pen head 203 is adjusted. Corresponding to the diameter, two limiting guides 303 restrict the state of the suction pen head 203 and the vehicle lens component 204. Then, the rotating module 201 drives the component suction pen 202 to rotate, so that the center line of the vehicle lens component 204 and the suction pen head 203 is aligned, thereby realizing the state correction of the vehicle lens component 204 and facilitating the precise assembly of the vehicle lens component 204. During the offset correction process of the vehicle lens component 204, the motion assembly module 2 with the vehicle lens component 204 maintains the state of moving from the feeding module 101 to the assembly module 102. Compared with the traditional clamping correction structure, the correction method of the present invention effectively reduces the stagnation effect of the motion assembly module 2 and effectively improves the assembly efficiency of the vehicle lens.

[0041] Figures 8 to 10 As shown, a component groove 304 is formed on the bottom surface of the limiting guide strip 303. The component groove 304 is lower than the bottom end of the suction tip 203, and the inner part of the component groove 304 is fixedly connected with abutment protrusions 305 at equal intervals. The outer end of the abutment protrusions 305 is flush with the outer surface of the limiting guide strip 303, and the outer end of the abutment protrusions 305 makes rolling contact with the outer ring of the vehicle lens component 204. When the suction tip 203 carries the vehicle lens component 204 and rolls on the limiting guide strip 303, the outer ring of the vehicle lens component 204 is provided with correction support by the abutment protrusions 305. Furthermore, the contact area between the vehicle lens component 204 and the limiting guide strip 303 is effectively reduced by the abutment protrusions 305, thereby further reducing the friction between the vehicle lens component 204 and the limiting guide strip 303.

[0042] When the two limiting guides 303 restrict the state of the pen tip 203 that has picked up the vehicle lens component 204, the component groove 304 portion of the limiting guide 303 is aligned with the vehicle lens component 204, and then only the abutting protrusion 305 is used to abut and support the vehicle lens component 204, effectively reducing the contact area between the vehicle lens component 204 and the limiting guide 303, thereby effectively reducing the friction between the vehicle lens component 204 and the limiting guide 303, and effectively reducing the frictional impact on the vehicle lens component 204.

[0043] Second implementation method:

[0044] Compared to the first embodiment, the main addition is a rotating belt ring 401, the specific addition structure is as follows, and the rest of the structure is the same as the first embodiment.

[0045] Figures 11 to 13 As shown, guide wheels 4 are rotatably connected to both ends of the limiting guide bar 303, and a rotating belt ring 401 is rotatably connected between the two guide wheels 4. The outer surface of the rotating belt ring 401 makes rolling contact with the pen suction head 203. By making rolling contact between the pen suction head 203 and the rotating belt ring 401, the friction between the vehicle lens component 204 and the limiting guide bar 303 is effectively reduced. A shaping ring 402 is fixedly connected to the middle of the rotating belt ring 401. The shaping ring 402 is made of high-density polyethylene material, and the rotating belt ring 401 is made of high molecular weight polyethylene material. The shaping ring 402 effectively improves the rotation of the belt ring. The structural strength of 401 facilitates the rotation of the rotating belt 401, and the high molecular weight polyethylene material of the rotating belt 401 has excellent wear resistance, effectively improving the service life of the rotating belt 401. The external of the shaping ring 402 is fixedly connected with a linkage tooth ring 403, and the external of the suction head 203 is provided with a linkage tooth groove 404. The linkage tooth ring 403 and the linkage tooth groove 404 are meshed and connected. By utilizing the meshing of the linkage tooth ring 403 and the linkage tooth groove 404, the rotating belt 401 can automatically follow the rotation of the suction head 203, effectively improving the self-rotation capability of the rotating belt 401.

[0046] When the two limiting guides 303 restrict the state of the suction head 203 that is picking up the vehicle lens component 204, the linkage groove 404 on the outside of the suction head 203 meshes with the linkage ring 403 on the outside of the shaping ring 402. During the rotation of the suction head 203, the linkage ring 403 and the linkage groove 404 mesh and transmit, and the rotating belt ring 401 automatically follows the rotation of the suction head 203, thereby realizing the rolling contact between the suction head 203 and the vehicle lens component 204 picked up by negative pressure and the rotating belt ring 401, effectively reducing the sliding friction force on the vehicle lens component 204 and effectively improving the state adjustment effect of the vehicle lens component 204.

[0047] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
