Description

Technical Field

[0001] The present invention relates to the technical field of parts assembly, in particular to a floating assembly mechanism. Background Art

[0002] Currently, the assembly of special-shaped lenses typically involves using a suction head to generate negative pressure to draw the lens from a material tray, then moving the suction head to engage the lens with the lens barrel to complete the assembly process. In existing technology, the suction head generates negative pressure to draw the lens, resulting in a random angle of the lens being drawn by the suction head. However, some high-end lens products have strict requirements for lens assembly angles. Traditional lens assembly machines are only capable of grasping and assembling lenses, and cannot meet the high-precision adjustment requirements of lenses. With a clearance of only 0.02mm between the lens and the inner wall of the assembled lens, inaccurate assembly can cause the lens to collide with the edge, resulting in damage during the assembly process and reduced lens assembly efficiency.

[0003] Therefore, it is necessary to design a floating assembly mechanism to solve the above problems. Summary of the Invention

[0006] Furthermore, the lifting module 2 is connected to the lifting module 1 through a support, and the lifting module 1 can drive the lifting module 2 to move up and down. The support is movably connected to the frame through guide rail 1, and a floating head is also provided on the support. The clamping mechanism is located at the bottom of the support, and the suction assembly includes a vacuum suction head.

[0007] Furthermore, the clamping mechanism includes clamping jaws symmetrically arranged along the height direction of the suction component. The symmetrically arranged clamping jaws can not only perform circular positioning on the lens but also eliminate errors in height positioning when the lens is assembled with the lens barrel.

[0008] Furthermore, the clamping mechanism also includes a driving cylinder adapted to the clamping jaws, and the opposing surfaces of the two clamping jaws are arc-shaped, so that the clamping jaws fit the lens more closely when positioning the lens, and the positioning is more precise.

[0009] Furthermore, a transverse slide rail is provided on the frame along its width direction, and the displacement cylinder drives the mobile placement platform to move along the transverse slide rail to the bottom of the suction assembly.

When the When the movable placement platform 43 moves to the bottom of the suction component 24, the lens can be placed and subsequently positioned; the lens barrel positioning tool 6 includes a positioning frame 61 corresponding to the position of the suction component 24, and the frame 1 is also provided with a limiting mechanism 5 that cooperates with the clamping mechanism 3. The lens barrel is placed in the positioning frame 61, and the telescopic cylinder 63 pushes the support block close to the side wall of the positioning frame 61 to support the lens barrel. The pressing cylinder 64 drives the pressing block 65 to press the lens barrel against the side wall of the positioning frame 61, thereby avoiding the phenomenon of lens barrel position deviation during the subsequent assembly process and improving the assembly efficiency.

[0022] See attached Figure 1 The lifting module 22 is connected to the lifting module 1 21 through the support 25. The lifting module 1 21 can drive the lifting module 22 to move up and down. The support 25 is movably connected to the frame 1 through the guide rail 1 23, and a floating head 33 is also provided on the support 25. The clamping mechanism 3 is located at the bottom of the support 25, and the suction component 24 includes a vacuum suction head.

[0023] See attached Figure 4The clamping mechanism 3 includes clamping jaws 31 symmetrically arranged along the height direction of the suction component 24. The symmetrically arranged clamping jaws 31 can not only perform circular positioning of the lens but also eliminate the error in height positioning when the lens is assembled with the lens barrel.

[0024] The clamping mechanism 3 further includes a driving cylinder 32 adapted to the clamping jaws 31 . The opposing surfaces of the two clamping jaws 31 are arc-shaped, so that the clamping jaws 31 fit the lens better when positioning the lens, and the positioning is more accurate.

[0025] See attached Figure 1 A transverse slide rail 41 is provided on the frame 1 along its width direction. The displacement cylinder 42 drives the mobile placement platform 43 to move along the transverse slide rail 41 to the bottom of the suction component 24. For the precise positioning of the special-shaped lens, it can be placed on the mobile placement platform 43 for adjustment.

[0026] See attached Figure 5 The limiting mechanism 5 includes a limiting bracket 51, and a displacement module 55 is provided on the limiting bracket 51. The displacement module 55 drives the limiting cylinder 54 to move back and forth along the guide rail 2 52, and a limiting clamp 56 is provided at the top end of the piston rod of the limiting cylinder 54. The limiting cylinder 54 is connected to the displacement module 55 through a sliding seat 53.

[0027] See attached Figure 2 The lens barrel positioning tool also includes a telescopic cylinder 63 located at the bottom of the positioning frame 61. The piston rod of the telescopic cylinder 63 extends to drive the supporting block 62 to move toward the inner wall of the positioning frame 61, thereby supporting the lens barrel. A pressing cylinder 64 is provided above the telescopic cylinder 63. The pressing cylinder 64 drives the pressing block 65 to press and position the lens barrel. The straight line in the length direction of the piston rod of the telescopic cylinder 63 is parallel to the straight line in the length direction of the piston rod of the pressing cylinder 64. The limiting mechanism 5 starts to work, and the displacement module 55 drives the limiting cylinder 54 to approach the lens. When the limiting cylinder 54 approaches the lens, the piston rod of the limiting cylinder 54 extends to drive the limiting clamping block 56 to move forward. A through groove is left on the limiting clamping block 56 to make way for the clamping jaw 31. The limiting clamping jaw 31 passes through the clamping jaw 31 and performs circumferential positioning on the lens.

[0028] Working principle: First, the lens barrel is placed in the lens barrel positioning fixture 6, and the telescopic cylinder 63 pushes the support block close to the side wall of the positioning frame 61 to support the lens barrel. The pressing cylinder 64 drives the pressing block 65 to press the lens barrel against the side wall of the positioning frame 61, and then a lens that needs to be assembled with the lens barrel is vacuum-adsorbed on the suction component 24, and the displacement cylinder 42 starts to work, driving the movable placement platform 43 to move along the transverse slide rail 41 to the bottom of the lens, and the lifting module 22 drives the suction component 24 to move downward so that the lens is located on the movable placement platform 43. At this time, the suction component 24 is de-energized and reset, and then the limiting mechanism 5 starts to work, and the displacement module 55 drives the limiting cylinder 54 to approach the lens. When the limiting cylinder 54 approaches the lens, the piston rod of the limiting cylinder 54 extends to drive the limiting clamp 56 to move forward, and the limiting clamp 56 is on A through groove is left for making way for the clamping jaws 31. The limiting clamping jaws 31 pass through the clamping jaws 31 and circumferentially position the lens. After the circumferential positioning is completed, the limiting mechanism 5 and the lens placement mechanism 4 are reset, and the lifting module 1 21 drives the clamping mechanism 3 to move downward close to the movable placement platform 43. The clamping jaws 31 on both sides work simultaneously to clamp the lens and perform circular positioning of the lens. After the two positionings are completed, the suction component 24 moves downward to suck the lens. Finally, the lifting module 1 21 continues to drive the clamping mechanism 3 to move downward, and the clamping mechanism 3 clamping jaws 31 are in a closed state at this time, until the closed clamping jaws 31 enter the lens barrel, and then open, and the position of the lens barrel is positioned by the outer circle of the clamping jaws 31. After the lens barrel position positioning is completed, the lifting module 2 22 drives the positioned lens to move downward into the lens barrel, thereby realizing the assembly of the lens barrel and the lens.
