New description: [New technology field] = Creative department is related to the use of lenses and other implanted core tube placement devices, especially for the help of guides and barrels. Two-stage buffer placement device with relative position. [Previous Technology] Many consumer electronic products commonly used today, such as mobile PDAs, digital cameras, and computer specials, can have photography or camera functions: that is, optical mirrors should be more and more widely used. The demand for the ground is also increasing. 'Therefore, an automated lens assembly device has been developed, which includes a placement device to place and fix components such as the mirror #, the pad 4, and the spacer in a lens barrel. The conventional device for assembling a lens mainly includes a lifting unit and a receiving unit, and the lifting unit can drive the receiving unit to move toward a lens barrel to place an advance on the lens barrel. Or the component adsorbed to the lower end of the receiving unit is press fit into the lens barrel tightly. In the foregoing pressing process, in order to avoid the relative position of the element and the lens barrel being inaccurate, many placement devices further include a buffer unit; some of the buffer units of the placement device are used to press the element under pressure. Shortly staying on the upper opening of the lens barrel to produce an automatic alignment effect with the lead angle of the upper opening; in addition, some of the buffering units of the placement device are used to slow the device to press the component into the lens barrel The speed to increase the stability of the unit and to adjust the position of the element more precisely. However, the alignment effect of the above two buffer units, M418199, is still limited and needs to be improved. [New content] In view of the above-mentioned counties, the main purpose of the above-mentioned counties is to provide a two-ample buffering device that can accurately place four pieces (such as lenses) into another component (4) such as (4). Increase its assembly accuracy and reduce the rate of non-performing. In order to achieve the above object, the two-stage buffering device provided by the present invention comprises: a base, a first buffer unit, a second buffer unit, and a mating unit, the first buffer unit having a connection The base is fixed. And a moving portion movable relative to the fixed portion of the 5H, the second buffer unit having an [end] connected to the moving portion of the first buffer unit, and a second end movable relative to the first end, and the The damping of the second buffer unit is different from the damping of the 帛-_ unit, and the material is connected to the second end of the second buffer unit. Thereby, the two-stage buffering can be used to place and fix an lens in the lens barrel. The method is such that the positioning device gradually approaches the lens barrel, and one end of the lens abuts the mirror. When the upper end of the cylinder is open and the other end is pushed by the receiving unit of the placing device that is continuously adjacent to the lens barrel, the reaction force first compresses the less damped unit of the two buffering units, and the receiving unit and the The lens moves relative to the base and the buffer unit and remains relatively stationary relative to the lens barrel until the buffer unit cannot be recompressed, and the other buffer unit that is more damped begins to compress, and the receiving unit and the receiving unit The lens will move relative to the base, and the speed of the moving unit will be less than that of the M418199. ΐ 'Therefore the object unit will slowly push against the lens opening, = mei for 5's the lens will briefly stay on the lens barrel above the ft phase of the two needles to reduce the 'domain' - Lai The relative position of the mirror 4 is adjusted by the _ segment type, and the accuracy is improved to reduce the defect rate. The detailed structure of the two-stage buffer placement device provided by this creation

A three-dimensional combination view of the buffering device; and a second to fifth drawing are cross-sectional views of the two-stage buffering device provided by the preferred embodiment of the present invention, showing the actuation process. Please refer to the first and second figures. The two-stage arranging device ω provided by the preferred embodiment includes a pedestal 2G, a plurality of first buffer S 30, a plurality of splicing units 4G, and a majority The second buffer unit 50. The number of the first and second buffer units 3〇, 50 and the receiving unit 40 is the same 'and the number is not limited'. There may also be only one set of the first and second slow 5 M418199 punching units 30, 50 and the receiving unit. 4〇. Each of the first buffer unit 30 has a fixing portion 32 connected to the base 20 and a moving portion % movable relative to the fixing portion 32. In this embodiment, the fixing portion of each of the first buffer units 30 32 is a gas pressure cylinder, and the moving portion 34 includes a piston rod 342 disposed on the fixing portion 32, a coupling member 344 connected to the end of the piston rod 342, and one end connected to the other end of the coupling member 344. An extension member 346 is movably disposed through the base 2 , and the extension member 346 is coaxially opposed to the piston rod 342 . The connector unit 40 has a connecting member 42 and a pressing member 44. The connecting member 42 is movably sleeved on the guiding post 22 of the base 2 and an extension of the first buffer unit 30. The member 346 is fixedly disposed on the connecting member 42 and is offset from the extending member 346. Further, the pressing member 44 is movably disposed through the base member 2b. In this embodiment, the pressing member 44 is a tubular body, and one end thereof is provided with a suction nozzle 46, and the other end is connected to a pneumatic source (not shown), so that the suction nozzle has 46 can be used to pick up an element to be mounted; however, the pressing member 44 can also be only a rod that can protrude from the base 2〇. Each of the second buffer units 50 is a compression spring that is sleeved on an extension 346 of the first buffer unit 30 and has a first end 51 and a second end 52. The first end 51 is The second end 52 is abutted against the connecting member 42 of the receiving unit 40. Further, the two-stage buffering device further includes a pneumatic control unit 60 for regulating the pneumatic cylinder of the first buffer unit 20. 6 It can be known from the foregoing that each of the third and fourth cymbals 50 can expand and contract the first buffer unit in the same direction, and the machine D that is not the extension of the present embodiment can also be a rotary cylinder' or each The first-slow=fixed portion 5... is the same as the axon, or the same as the air pressure: ☆:, τ is not r, the buffering element 3G, 5G need to have different damping and two different damping forces, in this implementation, The first large damping system is larger than the second buffer unit 5 by π 3 〇. Along the first and second buffering units 3:,: extension: the delivery unit and the second buffering unit::: Τ:: is parallel and deviates from the first and the first overall length than the i I axis' Placement device 10 Two buffer units =, 'However' the pressure piece 44 can also be associated with the first and second units 50. 5G is the same as _pair' or directly connected to the second buffer, 4=:2=: the segment buffer is placed in the 10th system for use in +not shown), and is not fixed. The component (the figure will be the same as the lens assembly) - the method is first, 7 pieces are adsorbed to the nozzle 46, and the first component is located directly above the 70, or, first Placing the first component on the second second-upper opening, and placing the pressing member 44 in the positive step of the first component = gradually bringing the skirt 10 closer to the second component, which ruins the base 2G is moved in a feeding direction, which is parallel to the moving direction of the moving portion % of the first buffer unit 3〇 and the direction of the second end 52 of the second buffer unit 5G relative to the first end Μ moving M418199 'meaning that the first and second buffer units 3G, 5G are in the direction of expansion and contraction; or, this step can also be achieved by moving the second element in the opposite direction of the feeding direction. 10, in the process of approaching the second component, when one end of the first component abuts against the opening of the second component, and the other end receives the connection When the unit 40 is pushed, the reaction force can cause the receiving unit 40 to push the second end 52 of the second buffer unit 50 toward the first end 51, that is, compress the second buffer unit 5〇, and the connection The object unit 4 is moved relative to the squat base 2〇 and the first buffer unit 3〇, and the object unit 4〇_ and the base 20 are moved in opposite directions at almost the same rate, therefore, the connection The object unit 40 and the first element are almost stationary relative to the second element. Until the second end 52 of the second buffer unit 5〇 can no longer move toward the first end 51 (as shown in the third figure), The receiving unit 4〇 starts to push the moving portion 34 toward the fixing portion 32 of the first buffer unit 3〇, and compresses the first buffer unit 3〇, at which time the damping force of the first buffer unit 30 is compared. Large, the rate at which the receiving unit 4 移动 moves relative to the pedestal 2 〇 φ is slowed down, so that the receiving unit 40 moves in the same direction as the pedestal 20 at a slower speed, and thus the first The component is pushed into the first element of the δ 玄. When the first buffer unit 3 〇 can no longer be compressed (such as As shown, the first component can be pushed to the position where it is to be installed. After that, the second buffer unit 5 will be restored to its original state as long as the first component is separated from the connector unit 40. The length (as shown in the fifth figure) 'The first buffer unit 3〇 will also be restored to return the placement device 10 to the state as shown in the second figure. 8 M418199 The user adjusts the fixation The air pressure in the portion 32 can change the damping of the first buffer unit 30, thereby adjusting the speed at which the receiving unit 40 pushes different first components, so that different first components can be pushed into the second component. More importantly, each of the first components will briefly stay above the opening of the second component and then slowly press into the second component, such that the first component and the second component The relative position of the two will be adjusted in two steps, which not only improves the assembly accuracy, but also reduces the rate of non-performing. Finally, it must be explained again that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Alternatives or variations of other equivalent elements should also be the scope of the patent application of the present application. Covered.
