[0003] At present, the ADB projection module realizes the functions of high and low beams, ADB, AFS, and DBL of the automotive headlight through the imaging method of a 4-lens combination. Among them, the 4 lenses are designed and assembled in the form of a barrel, which greatly reduces the influence of assembly tolerance on the imaging quality. First, the glass middle lens is assembled on the barrel bracket by the staff, and then the plastic middle lens is fixed on the barrel bracket by 3 screws. The glass middle lens is clamped by the plastic middle lens and the barrel bracket in a sandwich structure to complete the first barrel bracket assembly; the shielding frame is assembled on the first barrel bracket assembly, and the top lens is fixed on the first barrel bracket assembly by 3 screws to complete the production of the barrel assembly. However, the whole process of production and manufacturing requires manual operation, with low automation, which reduces work efficiency and increases the fatigue intensity of workers.

[0046] Please refer to Figures 1-13 , the present invention provides a technical solution: a lens barrel assembly of an ADB projection module and a device for producing the lens barrel, including a transportation component 3, a first lens assembly component 1, a second lens assembly component 2, a feeding component, a first fastening component 4, a second fastening component 7, and a combined assembly component 5; where:

[0047] The transportation component 3 includes a transportation track 301, and the transportation component 3 is used to carry the lens barrel bracket 6 and transport it along the transportation track 301

[0048] The first lens assembly component 1 is used to assemble the glass intermediate lens 601 into the lens barrel bracket 6

[0049] The feeding component is arranged above the first lens assembly component 1, and the feeding component is used to continuously convey the glass intermediate lens 601 into the first lens assembly component 1

[0050] The second lens assembly component 2 is used to assemble the plastic intermediate lens 602 into the lens barrel bracket 6 and cover the glass intermediate lens 601;

[0051] The fastening assembly 1 4 is used to absorb a plurality of screws and fasten the plastic intermediate lens 602 to the lens barrel bracket 6 to form the lens barrel bracket assembly 1 603;

[0052] The structure of the combined assembly component 5 is similar to that of the lens assembly component 2. The combined assembly component 5 is used to sequentially assemble the shielding frame 605 and the top lens 606 onto the lens barrel support component 1 603.

[0053] The structure of the fastening component 2 7 is similar to that of the fastening component 1 4 . The fastening component 2 7 is used to simultaneously fasten the shielding frame 605 and the top lens 606 to the lens barrel support component 1 603 to form the lens barrel support component 2 604 .

[0054] Specifically, the staff first places several lens barrel brackets 6 to be processed on the transport component 3 for transportation, and processes the lens barrel bracket 6 according to the assembly order. First, the glass intermediate lens 601 is assembled into the lens barrel bracket 6 through the lens assembly component 1, and a loading component is also provided to continuously replenish the glass intermediate lens 601 to the lens assembly component 1, thereby avoiding manual loading by workers and reducing the fatigue intensity of workers. Then, the lens assembly component 2 2 is used to assemble the plastic intermediate lens 602 on the lens barrel bracket 6 and cover it on the glass intermediate lens 601. Then, a number of screws are adsorbed by the fastening component 4 and tightened on the lens barrel bracket 6, thereby fixing the plastic intermediate lens 602. The intermediate lens 602 is fixed in the lens barrel bracket 6, and at the same time the glass intermediate lens 601 is pressed and fixed between the two, thereby forming a lens barrel bracket component 1 603. Afterwards, through the combined assembly component 5 which is arranged in the same structure as the lens assembly component 2 2, the shielding lining frame 605 and the top lens 606 are successively assembled to the lens barrel bracket component 1 603, and then the top lens 606 is screwed to the lens barrel bracket component 1 603 through the fastening component 2 7, and the shielding lining frame 605 is pressed between the two, thereby forming a lens barrel bracket component 2 604, that is, completing the integrated automatic assembly of the lens barrel bracket assembly, greatly improving work efficiency and high degree of automation.

[0055] The lens assembly component 1 includes a pair of oppositely arranged arc-shaped wedge bars 101. The centers of the arc-shaped wedge bars 101 are on the same axis as the center of the lens barrel bracket 6. A semi-circular plate 102 is fixedly connected to the upper end of the arc-shaped wedge bar 101. The semi-circular plates 102 are connected by a first telescopic rod 103. A first spring is arranged outside the first telescopic rod 103. The two ends of the first spring are respectively connected to the two semi-circular plates 102. A pair of arc-shaped clamping plates 104 are fixedly connected to the inner side of the semi-circular plate 102. The arc-shaped clamping plates 104 are used to clamp a number of glass intermediate lenses 601. The lower end of the arc-shaped clamping plate 104 extends beyond the lower end face of the arc-shaped wedge bar 101. A number of second telescopic rods 105 are arranged at the upper side ends of the arc-shaped clamping plate 104. A fixed outer cylinder 106 is arranged outside the second telescopic rod 105. A conveyor belt 107 is fixedly connected to the upper end of the fixed outer cylinder 106. Support columns are fixedly connected to the four corners of the conveyor belt 107. The lower ends of the support columns are fixedly connected to the transport track 301. A cylinder 9 is arranged below the transport track 301. The cylinder 9 is used to push the lens barrel bracket 6 up and down. The position of the cylinder 9 is arranged opposite to the arc-shaped wedge bar 101.

[0056] Specifically, a number of glass intermediate lenses 601 to be assembled are stacked in the arc-shaped clamping plates 104. And due to the elastic force of the first spring, the glass intermediate lenses 601 are clamped in the middle to prevent them from falling. When the lens barrel bracket 6 moves on the transport track 301 and moves to the middle position between the cylinder 9 and the arc-shaped wedge bar 101, the cylinder 9 is used to push the lens barrel bracket 6 upward, so that the upper end face of the lens barrel bracket 6 contacts the arc-shaped wedge bar 101. Along the inclined surface of the arc-shaped wedge bar 101, the two arc-shaped wedge bars 101 are pushed outward, and the semi-circular plates 102 and the arc-shaped clamping plates 104 are driven to separate to both sides. The first telescopic rod 103 and the second telescopic rod 105 are used for guiding. The first spring is stretched. At this time, the lower end of the arc-shaped clamping plate 104 extends into the inner side of the lens barrel bracket 6 and aligns with the groove inside for placing the glass intermediate lens 601. Since the arc-shaped clamping plates 104 separate to both sides, a number of glass intermediate lenses 601 clamped in the middle fall downward. The lowermost glass intermediate lens 601 falls into the groove, completing the assembly of the glass intermediate lens 601. And the upper glass intermediate lenses 601 contact the upper end face of the glass intermediate lens 601 in the groove and are still within the clamping range of the two arc-shaped clamping plates 104. After that, when the cylinder 9 drives the lens barrel bracket 6 to descend, under the reset action of the first spring, the arc-shaped clamping plates 104 return to their original positions, clamping a number of glass intermediate lenses 601 again, realizing the automatic separation and assembly of a single glass intermediate lens 601. The degree of automation is high. Only by setting a single cylinder 9 can the separation and assembly work be realized, saving costs.

[0057] The feeding component includes a fixed inner cylinder 108 which is arranged inside the fixed outer cylinder 106. The lower end of the fixed inner cylinder 108 is in contact with the arc-shaped clamping plate 104. The fixed inner cylinder 108 and the arc-shaped clamping plate 104 are on the same axis. The upper end surfaces of the fixed inner cylinder 108 and the fixed outer cylinder 106 are flush. A transmission channel is provided on the upper side of the conveyor belt 107, and the transmission channel is used to continuously transmit the glass intermediate lens 601 into the fixed inner cylinder 108.

[0058] Specifically, through the transmission channel in the conveyor belt 107, the glass intermediate lens 601 (not fully drawn in the figure) is continuously transmitted. Since the conveyor belt 107 is a prior art, it will not be elaborated here. The transmitted glass intermediate lens 601 enters the fixed inner cylinder 108, and with the opening and closing of the arc-shaped clamping plate 104, it orderly enters the middle of the clamping plates, realizing the automatic feeding and replenishment of the glass intermediate lens 601, without the need for manual feeding by workers, which is simple and convenient.

[0059] A number of moving disks 302 are arranged on the upper side of the transport channel 301. The number of moving disks 302 are in contact end to end. A material clamping disk 303 is arranged at the upper end of the moving disk 302. A mold groove opposite to the shape of the lower end of the lens barrel bracket 6 is provided on the upper side of the material clamping disk 303. Through holes are provided on the upper side of the moving disk 302. A number of telescopic columns 304 are arranged between the moving disk 302 and the material clamping disk 303. A piston rod is arranged on the upper side of the air cylinder 9, and the piston rod passes through the through hole to push the material clamping disk 303 to move up and down.

[0060] Specifically, when the staff installs the lens barrel bracket 6, they clamp it on the material clamping disk 303 and transport it through the movement of the moving disk 302. When it moves to the upper side of the air cylinder 9, the air cylinder 9 drives the piston rod to pass through the through hole on the moving disk 302 and jack up the material clamping disk 303 and the lens barrel bracket 6. The telescopic columns 304 are used for guiding and supporting, so as to start the assembly work of the glass intermediate lens 601.

[0061] The lens assembly component two 2 includes a support frame 201. One side of the support frame 201 is fixed to the upper end of the transport channel 301. A storage mechanism is arranged on the other side of the support frame 201. A number of fixed rods 202 are fixedly connected to the inner side of the upper side of the support frame 201. A translation plate 203 is arranged on the fixed rods 202. The translation plate 203 is driven by a linear drive mechanism. The fixed rods 202 penetrate through the translation plate 203 and are slidably matched with it. An air cylinder part is fixedly connected to the upper end of the translation plate 203. A number of telescopic rods three 204 are arranged at the lower end of the translation plate 203. A suction cover 205 is arranged at the lower end of the telescopic rods three 204. The air cylinder part is used to push the suction cover 205 to move up and down. The inner wall shape of the suction cover 205 is opposite to the shape of the plastic intermediate lens 602. A suction nozzle 206 is fixedly connected to the center of the suction cover 205. The suction nozzle 206 is connected to an air extraction pump. The suction nozzle 206 is used to adsorb the plastic intermediate lens 602 in the storage mechanism and send it into the lens barrel bracket 6.

[0062] Specifically, when the lens barrel bracket 6 assembled with the glass intermediate lens 601 moves to the lower side of the lens assembly component two 2, the translation plate 203 drives the cylinder part and the suction cap 205 to move to the upper side of the storage mechanism, and the fixed rod 202 is set as the guiding for the movement. Then, the cylinder part pushes the suction cap 205 to move downward. The suction cap 205 clamps the plastic intermediate lens 602 in the storage mechanism inside, adsorbs the plastic intermediate lens 602 through the inner suction nozzle 206. After that, it is brought back to the upper side of the lens barrel bracket 6 and placed into the lens barrel bracket 6 to complete the assembly.

[0063] The storage mechanism includes a bottom plate 207. One end of the bottom plate 207 is fixedly connected to the support frame 201, and the other end of the bottom plate 207 is fixedly connected to the transport path 301. A number of telescopic long rods 208 are arranged at the upper ends of the four corners of the bottom plate 207. The upper ends of the telescopic long rods 208 are provided with a lifting plate 209. A second spring is arranged outside the telescopic long rods 208, and the two ends of the second spring are respectively connected to the lifting plate 209 and the bottom plate 207. A storage cylinder 210 is fixedly connected to the middle side of the lifting plate 209. A number of vertical grooves are opened on the storage cylinder 210, and the vertical grooves extend to the lower end surface of the storage cylinder 210. Corresponding special-shaped holes are opened on the bottom plate 207. The storage cylinder 210 passes through the special-shaped holes and is in sliding fit with them. A number of plastic intermediate lenses 602 are stacked inside the storage cylinder 210. The inner wall size and shape of the storage cylinder 210 are the same as those of the suction cap 205.

[0064] Specifically, the staff pre-places a number of stacked plastic intermediate lenses 602 in the storage cylinder 210. The storage cylinder 210 sorts, limits and stacks the plastic intermediate lenses 602, and the bottom plate 207 is arranged at the lower side to support a number of lenses. Since a number of special-shaped holes are arranged on the bottom plate 207 and the storage cylinder 210 is provided with corresponding vertical grooves, the storage cylinder 210 can be inserted into the special-shaped holes for sliding. When the suction cap 205 descends for suction, the lifting plate 209 and the storage cylinder 210 are pressed down, and the telescopic long rods 208 and the second spring are compressed. At this time, the positions of a number of plastic intermediate lenses 602 remain unchanged, so that the suction cap 205 can adsorb the uppermost plastic intermediate lens 602. When the suction cap 205 leaves, under the reset action of the second spring, the storage cylinder 210 and the lifting plate 209 return to their original positions. Such a setting can ensure that the position of the plastic intermediate lens 602 is accurate and does not shift. From the storage cylinder 210 to the suction cap 205, and then to the lens barrel bracket 6, the position of the plastic intermediate lens 602 can be ensured not to shift, ensuring the installation accuracy.

[0065] The first fastening assembly 4 includes a screw vibrating plate 401 and a sorting track 402. The screw vibrating plate 401 is used to sort a number of screw parts and sequentially transfer them onto the sorting track 402. A lifting mechanism is provided on the translation plate 203. A rotating disk 404 is provided on the lower side of the lifting mechanism. Three sprockets 405 are rotatably connected to the lower end of the rotating disk 404. A chain is meshed and connected to the outer sides of the three sprockets 405. The sprockets 405 are driven to rotate by a motor assembly. A magnetic screwdriver bit 406 is fixedly connected to the lower end of the sprocket 405. The magnetic screwdriver bit 406 is used to adsorb the screw parts on the sorting track 402 and fasten the plastic intermediate lens 602 to the lens barrel bracket 6. A guide tube 407 is provided on the outer side of the magnetic screwdriver bit 406. The magnetic screwdriver bit 406 is slidably matched with the guide tube 407. A connecting piece 408 is fixedly connected to one side of the guide tube 407. A fourth telescopic rod 409 is provided at the upper middle side of the connecting piece 408. The upper end of the fourth telescopic rod 409 is connected to the rotating disk 404. A fourth spring is provided on the outer side of the fourth telescopic rod 409. The two ends of the fourth spring are respectively connected to the rotating disk 404 and the connecting piece 408. The lower end of the guide tube 407 extends beyond the lower end face of the magnetic screwdriver bit 406.

[0066] Specifically, the screw vibrating plate 401 is a prior art. It sorts a number of screw parts and sequentially feeds them into the sorting track 402. Similarly, the translation plate 203 drives the lifting mechanism to translate, and then the lifting mechanism controls the up and down movement of the rotating disk 404, the sprockets 405, the magnetic screwdriver bit 406 and the guide tube 407. The guide tube 407 first contacts the screw part, so that the screw part is caught inside the guide tube 407 for positioning. Then the magnetic screwdriver bit 406 moves downward along the inside of the guide tube 407, and the fourth spring is compressed. The bit adsorbs the screw part on the sorting track 402 and lifts it up. The fourth spring resets, so that the screw part is restricted inside the guide tube 407. Then, by rotating the rotating disk 404, the magnetic screwdriver bit 406 is driven to rotate, so that the remaining two magnetic screwdriver bits 406 sequentially adsorb the screw parts. Then, it moves to the upper side of the lens barrel bracket 6 with two lenses already assembled through the translation plate 203. The lifting mechanism drives the three magnetic screwdriver bits 406 and the guide tube 407 to descend. Similarly, the guide tube 407 first correspondingly contacts the threaded hole of the upper plastic intermediate lens 602 and presses it to fit tightly with the lens barrel bracket 6. As the magnetic screwdriver bit 406 drives the adsorbed screw part and descends along the guide tube 407, the screw part is inserted into the threaded hole. Then, one of the sprockets 405 is driven to rotate by the motor assembly, and through chain drive, the other two magnetic screwdriver bits 406 are simultaneously driven to rotate, and the screw part is screwed tightly into the threaded hole to realize the fastening of the plastic intermediate lens 602, forming the first lens barrel bracket assembly 603. There is no need for manual screwing, which greatly reduces the fatigue strength of the staff. And the fastening assembly and the assembly component are all arranged on the translation plate 203 to displace and pick up materials, reducing the processing cost.

[0067] The lifting mechanism includes a gear column 403 which passes through the translation plate 203 and is in sliding fit with it. The lower end of the gear column 403 is fixedly connected to a rotating disk 404. The upper end of the gear column 403 is rotatably connected to a cover plate 410. One side of the cover plate 410 is provided with a threaded rod 411 which passes through the cover plate 410 and has a clearance fit with it. The upper end of the cover plate 410 is rotatably connected to an electromagnet ring 412. The threaded rod 411 passes through the electromagnet ring 412 and is threadedly connected to it. The cover plate 410 is made of magnetic metal. The lower end of the threaded rod 411 is fixedly connected to a rotating shaft 902. The lower end of the rotating shaft 902 is provided with a motor 901 which is fixedly connected to the translation plate 203. One side of the rotating shaft 902 is rotatably connected to a spur gear 413 which is meshed with the gear column 403. The upper end of the spur gear 413 is fixedly connected to an electromagnet ring 414. The rotating shaft 902 passes through the electromagnet ring 414 and is magnetically connected to it. The rotating shaft 902 is made of magnetic metal.

[0068] Specifically, when it is necessary to control the lifting mechanism to lift, start the motor 901 to drive the rotating shaft 902 and the threaded rod 411 to rotate. At this time, the electromagnet ring 414 is powered off and the electromagnet ring 412 is powered on, so that the electromagnet ring 412 adsorbs to the cover plate 410. When the threaded rod 411 rotates, the threaded rod 411 is threadedly connected to the electromagnet ring 412. Since the electromagnet ring 412 and the cover plate 410 are integrated, and since the gear column 403 is in sliding fit with the translation plate 203, the cover plate 410 drives the gear column 403 to move up and down, that is, the rotating disk 404 is moved, and the lifting of the magnetic screwdriver head 406 can be realized. And since the electromagnet ring 414 is in a powered-off state, that is, separated from the rotating shaft 902, when the rotating shaft 902 rotates, it will not drive the electromagnet ring 414 and the spur gear 413 to rotate together, nor will it be meshed with the gear column 403 to drive it to rotate. When it is necessary to rotate the rotating disk 404, at this time the electromagnet ring 414 is powered on and the electromagnet ring 412 is powered off, so that the rotating shaft 902 drives the spur gear 413 to rotate, and the spur gear 413 drives the gear column 403 to rotate, and the rotation of the screwdriver head can be realized. And at this time the electromagnet ring 412 is separated from the cover plate 410, so that the electromagnet ring 412 will only rotate self-driven under the drive of the threaded rod 411, and will not drive the cover plate 410 to move up and down. By controlling the power-on and power-off of the electromagnet ring, with one motor 901, the two functions of lifting and rotation can be realized, saving the processing cost.
