Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens processing equipment, and in particular to a rotary pressing mechanism for lenses. Background Technology
[0002] In the processing of optical filters, a layer of ink is typically applied to the lens to achieve the desired filtering effect. With increasing automation, lenses are now fed, unloaded, and coated with ink via a rotary table, effectively improving processing efficiency.
[0003] The turntable has multiple circumferentially distributed slots to position the lens. However, the area of the slot is generally larger than that of the lens to facilitate its placement. However, due to the influence of clamping and displacement accuracy, there is usually a gap between the lens and the wall of the slot. Therefore, when the screen printing equipment closes, problems such as lens bending may easily occur, resulting in uneven ink distribution or damage.
[0004] The current method uses vacuum adhesion to achieve lens bonding. However, due to ink printing, ink overflow is inevitable, which can affect the adsorption channels. Therefore, regular cleaning is required, making production quite troublesome. Utility Model Content
[0005] The main purpose of this invention is to propose a rotary pressing mechanism for lenses, which aims to improve existing lens bonding methods, reduce damage to lenses, and improve processing stability.
[0006] To achieve the above objectives, this utility model proposes a rotary pressing mechanism for lenses, comprising: The frame includes a rotatable turntable with circumferentially distributed grooves to accommodate lenses. The frame is equipped with a first drive device to drive the turntable to rotate in a specific direction; The elevation frame is equipped with a linear drive device along the horizontal direction, and the linear drive device is equipped with a telescopic device. The telescopic device is equipped with a base. The base is provided with a slidingly mounted adjusting seat, and an elastic device is provided between the base and the adjusting seat; The bottom wall of the adjusting seat is provided with four rectangularly distributed elastic pressure seats. The elastic pressure seats are made of flexible material and have hollow channels, which are connected to the air blowing device.
[0007] In actual processing, after the lens is placed in the groove, a predetermined air pressure is applied to the lens through an air blowing device to achieve preliminary correction. Then, the lens is adhered to the upper wall of the lens by an elastic pressure seat to achieve a good fit between the lens and the groove wall. At the same time, the double elastic stroke effectively reduces wear on the lens and improves the stability of the pressing. Attached Figure Description

[0013] like Figures 1 to 3 As shown, a rotating disk 11 pressing mechanism for lenses includes: The frame 1 is equipped with a rotatable turntable 11, which has circumferentially distributed grooves to accommodate lenses. The frame 1 is equipped with a first drive device 12 to drive the turntable 11 to rotate in a specific direction; The elevation frame 2 is equipped with a linear drive device 21 along the horizontal direction, and the linear drive device 21 is equipped with a telescopic device 22. The telescopic device 22 is provided with a base 31. The base 31 is provided with a slidingly mounted adjustment seat 32, and an elastic device is provided between the base 31 and the adjustment seat 32; The bottom wall of the adjusting seat 32 is provided with four rectangularly distributed elastic pressure seats 5. The elastic pressure seats 5 are made of flexible material and have hollow channels, which are connected to the air blowing device.
[0014] In actual processing, after the lens is placed in the groove, a predetermined air pressure is applied to the lens through an air blowing device to achieve preliminary correction. Then, the elastic pressure seat 5 is attached to the upper wall of the lens to achieve a good fit between the lens and the groove wall. At the same time, the double elastic stroke effectively reduces wear on the lens and improves the stability of the pressing.
[0015] Specifically, the elastic device is a spring assembly, which enables secondary elastic pressing and reduces damage to the lens from the flexible pressure seat.
[0016] In this embodiment of the utility model, the middle part of the adjusting seat 32 is provided with a guide sleeve 61, and the middle part of the base 31 is provided with a guide rod 62 that cooperates with the guide sleeve 61, thereby ensuring the relative sliding between the two.
[0017] Specifically, the first driving device 12 is a rotary motor and a reducer that cooperates with the rotary motor, thereby enabling the turntable 11 to rotate at a predetermined angle.
[0018] In this embodiment of the utility model, the linear drive device 21 includes a linear guide rod disposed on the lifting frame 2, a linear slider slidably mounted on the linear guide rod, and a linear lead screw pair for driving the linear slider to move. The telescopic device 22 is disposed on the linear slider, and the linear lead screw pair can also be a telescopic motor.
[0019] Specifically, the telescopic device 22 is a vertical telescopic motor, and the base 31 is located at the drive end of the vertical telescopic motor.
[0020] In this embodiment of the invention, the elastic pressure seat 5 is provided with a plurality of folding portions 50, thereby forming a deformation range and reducing the force on the lens.
[0021] Specifically, the adjusting seat 32 is provided with recessed holes 71 on both sides, and the base 31 is provided with a vertical rod 72 that cooperates with the recessed holes 71. The cooperation between the recessed holes 71 and the vertical rod 72 can be adjusted during debugging by observing the relative displacement between the adjusting seat 32 and the base 31 through different lenses, thereby replacing or adjusting the elastic element 4. The elastic element 4 can generally be adjusted by adjusting the relative spring compression ratio through a nut.
[0022] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
