Description

Technical Field

[0001] This utility model relates to the technical field of lens assembly, specifically to a lens assembly device and a lens assembly production line. Background Technology

[0002] Lens assembly involves assembling multiple lens elements and spacers within the lens barrel. A Chinese utility model patent application (CN119820307A) discloses a lens assembly method and equipment. This method involves pre-placing multiple lens elements and spacers in a single tray, then assembling them sequentially into the lens barrel. While this method allows assembly of all components on a single machine, it requires precise pre-positioning of all components within the tray, placing high demands on the operator's accuracy and increasing the risk of misalignment leading to poor lens assembly. Furthermore, this method of placing all components in a single tray results in rapid component consumption, necessitating frequent tray replacements. Additionally, the method relies solely on placement slots for positioning the lens barrel and lens elements during assembly, resulting in low assembly precision. Utility Model Content

[0003] The purpose of this utility model is to provide a lens assembly device, including a base plate. The base plate is equipped with a lens feeding mechanism, a lens barrel transport mechanism, a lens barrel transfer mechanism, a lens barrel positioning mechanism, a lens assembly mechanism, and a lens barrel cutting mechanism. The lens feeding mechanism carries a tray for storing lenses. The lens barrel transport mechanism transfers the lens barrels cut from the previous machine to the lens barrel transfer mechanism. The lens barrel positioning mechanism obtains the coordinate position of the lens barrel on the lens barrel transfer mechanism. The lens assembly mechanism picks up the lenses from the tray and assembles the lenses into the lens barrel according to the obtained lens barrel coordinate position. The lens barrel transport mechanism also transfers the lens barrel after lens assembly to the lens barrel cutting mechanism, which cuts the lens barrel to the next machine.

[0004] In one specific embodiment, two sets of the lens feeding mechanism, lens barrel transfer mechanism, and lens assembly mechanism are provided. The lens barrel transport mechanism alternately docks with the two lens barrel transfer mechanisms, and the lens barrel positioning mechanism alternately docks with the two lens barrel transfer mechanisms.

[0010] In one specific implementation, the second X-axis linear module and the third X-axis linear module are both set at the same horizontal height, or the second X-axis linear module is higher than the third X-axis linear module.

[0011] In one specific embodiment, the lens barrel cutting mechanism includes a fourth X-axis linear module disposed on the edge of the equipment base plate, and a carrier for carrying the lens barrel is disposed on the drive slider of the fourth X-axis linear module.

[0012] In one specific embodiment, a lens Y-axis alignment gripper and a lens detection camera are also provided between the Y-axis linear module for picking up and placing the lens and the lens barrel transfer mechanism. After the suction pen picks up the lens from the tray, it is first aligned by the lens Y-axis alignment gripper, and then the lens coordinate position relative to the center of the suction pen is obtained by the lens detection camera. Finally, the lens is assembled into the lens barrel on the lens barrel transfer mechanism.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] Please see Figures 1-3 This utility model provides a lens assembly device 100, including a base plate 1. The base plate 1 is equipped with a lens feeding mechanism 2, a lens barrel transport mechanism 3, a lens barrel transfer mechanism 4, a lens barrel positioning mechanism 5, a lens assembly mechanism 6, and a lens barrel cutting mechanism 7. The lens feeding mechanism 2 carries a tray 8 for storing lenses. The lens barrel transport mechanism 3 transfers lens barrels cut from the previous machine to the lens barrel transfer mechanism 4. The lens barrel positioning mechanism 5 obtains the coordinate position of the lens barrel on the lens barrel transfer mechanism 4. The lens assembly mechanism 6 picks up the lenses from the tray 8 and assembles them into the lens barrel according to the obtained lens barrel coordinate position. The lens barrel transport mechanism 3 also transfers the assembled lens barrel to the lens barrel cutting mechanism 7, which cuts the lens barrel to the next machine.

[0034] Two sets of lens feeding mechanism 2, lens barrel transfer mechanism 4, and lens assembly mechanism 6 are provided. Lens barrel transport mechanism 3 alternately engages with the two sets of lens barrel transfer mechanisms 4, and lens barrel positioning mechanism 5 alternately engages with the two sets of lens barrel transfer mechanisms 4, thereby improving assembly efficiency. Of course, in other embodiments, depending on market demand, only one set of lens feeding mechanism 2, lens barrel transfer mechanism 4, and lens assembly mechanism 6 may be provided.

[0035] Please see Figures 4-5 The lens feeding mechanism 2 includes a square tube hopper body 21, a hopper lifting screw 22, and a Y-axis linear module 23 for picking up and placing lenses. The hopper lifting screw 22 is connected to the equipment base plate 1, and its drive end is connected to the square tube hopper body 21 to drive the hopper body 21 to perform lifting and lowering actions. Multiple layers of trays 8 are placed inside the square tube hopper body 21, and the trays 8 are placed on a pair of ribs 211, which are integrally formed and fixed to the inner wall of the square tube hopper body 21. The Y-axis linear module 23 for picking up and placing lenses is mounted on the equipment base plate 1, and a picking plate 231 for supporting the trays 8 is connected to the drive slider of the Y-axis linear module 23. During operation, multiple trays 8 containing arranged lenses are first placed into the square tube hopper 21. The Y-axis linear module 23 drives the pick-up plate 231 into the square tube hopper 21, positioning it below the designated layer of trays 8. The lifting screw 22 then drives the square tube hopper 21 to descend, causing the trays 8 to fall onto the pick-up plate 231. A pressing cylinder is installed on the pick-up plate 231, which fixes the trays 8 onto it. The Y-axis linear module 23 then transfers the trays 8 out of the square tube hopper 21 and moves them below the lens assembly mechanism 6, allowing the lens assembly mechanism 6 to pick up the lenses.

[0036] Please see Figure 3 A gantry frame 11 is provided on the base plate 1 of the equipment. The lens barrel transport mechanism 3 includes a first X-axis linear module 31 provided on the first side of the gantry frame 11. A first Z-axis linear module 32 is provided on the drive slider of the first X-axis linear module 31. A cylinder gripper 33 for gripping the lens barrel is connected to the drive slider of the first Z-axis linear module 32. The cylinder gripper 33 is used to transfer the lens barrel cut out by the previous machine to the lens barrel transfer mechanism 4, and to transfer the lens barrel with the lens assembled on the lens barrel transfer mechanism 4 to the lens barrel cutting mechanism 7.

[0037] Please see Figure 6 The lens barrel transfer mechanism 4 includes a Y-axis linear module 41 mounted on the equipment base plate 1. A heating plate 42 for placing the lens barrel is mounted on the drive slider of the Y-axis linear module 41. A cylinder gripper 33 transfers the lens barrel cut from the previous machine to the heating plate 42 for heating, causing the inner diameter of the lens barrel to expand due to heat, making it easier to assemble the lens into the lens barrel. Of course, in other embodiments, for lens barrels that are not sensitive to thermal expansion, the heating function of the heating plate 42 may not be activated; the heating plate 42 may only be used to support the lens barrel, or the heating plate 42 may be directly replaced with a support plate without heating function.

[0038] Please see Figure 7The lens barrel positioning mechanism 5 includes a second X-axis linear module disposed on the second side of the gantry 11. A second Z-axis linear module 52 is disposed on the drive slider of the second X-axis linear module. A lens barrel detection camera 53 is disposed on the drive slider of the second Z-axis linear module 52. The lens barrel detection camera 53 is used to obtain the accurate coordinate position of the lens barrel that has been heated in the heating plate 42, so as to facilitate more precise assembly of the lens into the lens barrel.

[0039] The lens assembly mechanism 6 includes a third X-axis linear module disposed on the second side of the gantry 11. A third Z-axis linear module 62 is disposed on the drive slider of the third X-axis linear module. A suction pen and a lens detection camera 63 are disposed on the drive slider of the third Z-axis linear module 62. A suction pen head 64 is inserted into and magnetically fixed to the suction pen. The lens detection camera 63 detects the appearance and orientation of the lens in the tray 8 on the Y-axis linear module 23 and obtains its coordinate position. The suction pen head 64 then picks up the lens according to the qualified lens coordinate position, under the cooperative action of the third X-axis linear module and the third Z-axis linear module 62, and assembles it into the lens barrel. Of course, in other embodiments, the suction pen and the suction pen head 64 can also adopt a direct insertion or direct magnetic connection structure.

[0040] The second X-axis linear module and the two third X-axis linear modules are coaxially positioned at the same horizontal level. (For further information, please refer to...) Figure 8 In other embodiments, the second X-axis linear module is independently positioned above the two coaxial third X-axis linear modules. By placing both the lens detection camera 63 and the lens barrel detection camera 53 on the linear module, it is possible to move directly above the object being detected, resulting in higher detection accuracy and higher coordinate acquisition accuracy.

[0041] Please see Figure 1 and Figure 9 The lens barrel cutting mechanism 7 includes a fourth X-axis linear module 71 set on the edge of the equipment base plate. The drive slider of the fourth X-axis linear module 71 is provided with a carrier 72 for carrying the lens barrel. The fourth X-axis linear module 71 can drive the carrier 72 to move to the next machine space, thereby realizing the cutting of the lens barrel to the next machine.

[0042] Please see Figure 1 and Figure 10 Between the Y-axis linear module 23 and the lens barrel transfer mechanism 4, there is also a lens Y-axis alignment gripper 12 and a lens detection camera 13. After the suction pen head 64 picks up the lens from the material tray 8, it first passes through the lens Y-axis alignment gripper 12 for alignment, and then passes through the lens detection camera 13 to obtain the coordinate position of the lens relative to the center of the suction pen. Then the lens is assembled into the lens barrel on the lens barrel transfer mechanism 4 to achieve more precise assembly of the lens into the lens barrel.

[0043] Please see Figure 1 and Figure 5 The equipment base plate 1 also includes a pen suction magazine 14, located on the side of the lens feeding mechanism 2 away from the lens barrel transfer mechanism 4. The pen suction magazine 14 further includes a base plate 141, which is fixed to the drive slider of the Y-axis linear module 23. The base plate 141 has a carrier plate 142 for accommodating multiple pen suction heads 64. A clamping cylinder is mounted on the carrier plate 142, and a clamping plate 143 is mounted on the drive end of the clamping cylinder. The clamping plate 143 extends above the carrier plate 142 to constrain the pen suction heads 64 onto the carrier plate 142. By providing the pen suction magazine 14, different pen suction heads 64 can be switched between depending on the assembled components, thanks to the coordinated action of the third X-axis linear module, the third Z-axis linear module 62, the Y-axis linear module 23, and the clamping cylinder. Alternatively, in other embodiments, a separate linear module can be provided to drive the base plate 141 to slide.

[0044] Please see Figure 1 and Figure 11 An electrostatic eliminator 15 is also installed on the equipment base plate 1. The electrostatic eliminator 15 spans above the lens barrel transfer mechanism 4 and is fixed to the equipment base plate 1 by a column 151. By installing the electrostatic eliminator 15, static electricity on various components during the assembly process is removed, reducing the accumulation of dust and other contaminants.

[0045] Please see Figures 12-14 This utility model also provides a lens assembly production line, including a lens barrel feeding device 200 and a finished product receiving device 300. Multiple lens assembly devices 100 are sequentially connected between the lens barrel feeding device 200 and the finished product receiving device 300. The lens barrel feeding device 200 is also equipped with a lens barrel cutting mechanism 7. The lens barrel feeding device 200 includes a lens barrel feeding mechanism, a lens barrel conveying mechanism 3, and a lens barrel cutting mechanism 7 connected in sequence. The finished product receiving device 300 includes a lens barrel conveying mechanism 3 and a finished product receiving mechanism. The lens barrel feeding mechanism and the finished product receiving mechanism have the same structure as the lens feeding mechanism 2, except that the operation flow of the finished product receiving mechanism is reversed compared to the lens feeding mechanism 2. The lens barrels are transferred between the machines through the lens barrel cutting mechanism 7.

[0046] Of course, in other embodiments, the lens barrel feeding device 200 and the finished product receiving device 300 can also be feeding and receiving devices that can be docked with the lens barrel cutting mechanism 7 of this utility model in the prior art.

[0047] It should be noted that the various linear modules used in the embodiments of this utility model can be selected from various existing technologies that can achieve linear drive, such as lead screw linear modules, synchronous belt linear modules, and cylinder linear modules, as needed.

[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
