Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, and in particular to an automatic lens dispensing and focusing machine. Background Technology

[0002] As is well known, in the lens assembly and production process, the lens elements and spacers need to be installed into the lens barrel in sequence first. Then, glue is applied to the lens barrel to fix the spacers in the lens barrel and prevent the lens elements from falling off. At the same time, after the lens glue application is completed, the lens needs to be focused to ensure that the final focal length of the lens can meet the production requirements.

[0003] Currently, in order to improve the quality of lenses, a dispensing machine is usually used to apply adhesive to the lens. After the lens manufacturing is completed, the lens is manually removed by the operator for testing and focusing. This requires the lens to be moved from the dispensing machine to the focusing machine, which is inefficient. It can also cause positioning deviations when the lens is changed between worktables, and may even cause the lens to be scratched and scrapped during the transfer process. Utility Model Content

[0034] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] In the description of this utility model, it should be noted that the directional terms such as "X direction", "Y direction", "Z direction" indicate the direction based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that technical feature.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses an automatic lens dispensing and focusing machine, which includes: a frame 1 and a dispensing mechanism 2, a transmission mechanism 3, a focusing mechanism 4, and a control mechanism 5 disposed on the frame 1. The dispensing mechanism 2, the transmission mechanism 3, and the focusing mechanism 4 are all controlled by the control mechanism 5 through communication connection. In this utility model, the dispensing mechanism 2 is specifically disposed above the transmission mechanism 3, and the dispensing mechanism 2 is provided with a dispensing component 21, a CCD image sensor 22, and a height sensor 23. The focusing mechanism 4 is specifically disposed at one end of the transmission mechanism 3. The transmission mechanism 3 includes an X-axis guide rail 31 and a support platform 32 for carrying the lens 33 to be processed. The support platform 32 is slidably disposed on the X-axis guide rail 31 to move closer to the dispensing mechanism 2 or the focusing mechanism 4 along the extension direction of the X-axis guide rail 31, i.e., in the X direction.

[0038] It should be noted that in practical applications, such as Figure 2 As shown, the reason why the dispensing mechanism 2 is equipped with the dispensing component 21 is to facilitate the dispensing of the lens 33 to be processed on the carrier platform 32 when the carrier platform 32 moves to the dispensing station of the dispensing mechanism 2, so as to use the glue to fix the spacer in the lens barrel and prevent the lens from falling off. At the same time, in order to accurately dispense the lens 33 to be processed, before dispensing, the CCD image sensor 22 will take an image of the carrier platform 32 from top to bottom to obtain the X and Y coordinates of the lens 33 to be processed in the spatial coordinate system, and the height sensor 23 will detect the height information of the lens 33 to be processed on the carrier platform 32 to obtain the Z coordinate of the lens 33 to be processed in the spatial coordinate system.

[0039] Therefore, after obtaining the three-axis coordinates of the lens 33 to be processed in the spatial coordinate system, the position of the dispensing mechanism 2 and / or the support platform 32 in the spatial coordinate system can be adjusted to accurately dispense the lens 33 to be processed on the support platform 32.

[0040] Furthermore, it should be noted that in order to accurately adjust and control the position of the lens to be processed 33 in the spatial coordinate system, the structure of the support platform 32 can be optimized to include a mounting base 321, a positioning plate 322, and a driving device 323. The mounting base 321 is slidably mounted on the X-guide rail 31, and the positioning plate 322 is mounted on the mounting base 321. The upper surface of the positioning plate 322 is used to mount the lens to be processed 33. The driving device 323 is used to drive the positioning plate 322 to move relative to the mounting base 321 in the X, Z, and Y directions, thereby adjusting the position of the positioning plate 322 and the lens to be processed 33 mounted on the positioning plate 322 in the spatial coordinate system.

[0041] Accordingly, after obtaining the three-axis coordinates of the lens to be processed 33 in the spatial coordinate system, the position of the lens to be processed 33 in the spatial coordinate system is adjusted accordingly, and the lens to be processed 33 is glued by the glue dispensing mechanism 2. In practical application, after adjusting the positioning plate 322 to a suitable vertical height position, the driving device 323 of the support platform 32 can drive the positioning plate 322 to move in an arc shape on the horizontal plane in the X and Y directions, so that the glue dispensing part 21 of the glue dispensing mechanism 2 can dispense glue around the annular peripheral wall of the lens to be processed 33. After precise glue dispensing, the support platform 32 can be controlled to move along the X guide rail 31 to approach the focusing mechanism 4, thereby moving to the focusing position of the focusing mechanism 4, and the lens to be processed 33 on the support platform 32 is automatically focused to a preset focal length value by the focusing structure.

[0042] See Figure 3 , Figure 4 and Figure 5 As shown, in actual operation, in order to facilitate dispensing, the dispensing mechanism 2 designed in this embodiment specifically includes a mounting plate 24 and a first Z-guide rail 25. The mounting plate 24 is slidably disposed on the first Z-guide rail 25, which extends along the vertical height direction, that is, along the Z direction. The dispensing component 21, the CCD image sensor 22, and the height sensor 23 are all disposed on the mounting plate 24, so that when the mounting plate 24 is driven by the driving component to move along the extension direction of the first Z-guide rail 25, the dispensing component 21, the CCD image sensor 22, and the height sensor 23 can also move synchronously in the vertical height direction.

[0043] Accordingly, in this embodiment, the dispensing component 21 includes a dispensing cylinder 211 and a dispensing head 212. The dispensing cylinder 211 is mounted on the mounting plate 24 of the dispensing mechanism 2, and one end of the dispensing cylinder 211 is connected to an external air source through an air pipe. The other end of the dispensing cylinder 211, near the support platform 32, is connected to the dispensing head 212. The mounting plate 24 is also provided with a second Z-axis guide rail 26, on which the dispensing cylinder 211 is slidably mounted. The dispensing cylinder 211 can be controlled to slide on the second Z-axis guide rail 26 according to actual conditions via a driving component. In practical applications, the operator can control the amount of air supplied to the dispensing cylinder 211 via an air pipe to indirectly control the air pressure inside the dispensing cylinder 211. Finally, the air pressure is used to push the glue stored in the dispensing cylinder 211 out through the dispensing head 212 at the other end, thus achieving dispensing.

[0044] like Figure 7 and Figure 8As shown, in this embodiment, the focusing mechanism 4 includes an adjusting member 41 and a lifting drive member 42. The adjusting member 41 is connected to the lifting drive member 42, and the lifting drive member 42 drives the adjusting member 41 to move up and down in the vertical direction. In practical applications, this focusing mechanism 4 can focus the lens to be tested using AA (Active Alignment) focusing. In practical applications, AA focusing is not "focusing" in the traditional sense (i.e., adjusting the focal length to make the image clear), but rather using active alignment technology to achieve high-precision position adjustment between the lens and the sensor, so as to cure the adhesive in the optimal position state, fix the relative position of the lens and the sensor, and ensure the best imaging effect.

[0045] In practical applications, the aforementioned adjusting member 41 includes at least two grippers 43 arranged opposite to each other, with a gap between adjacent grippers 43. The grippers 43 are positioned close to the X-guide rail 31, and the adjacent grippers 43 are used to clamp and fix the lens 33 to be processed on the support platform 32. That is, since the adhesive on the lens 33 has not yet cured, the adjacent grippers 43 can correspondingly clamp the lens 33, and under the drive of their own lifting drive member 42, control the grippers 43 and the focusing lens of the lens 33 they clamp to adjust their position in the vertical height direction, thereby adjusting the lens 33 to a suitable focal length.

[0046] like Figure 8 As shown, in practical applications, the end of the gripper 43 near the guide rail is provided with a curved part 44. The curved parts 44 of two adjacent grippers 43 together form a receiving opening. This receiving opening is used to receive the lens 33 to be processed, so as to prevent the lens 33 to be processed from coming loose due to unstable clamping when focusing the lens 33 later, thereby improving the stability and reliability of the equipment.

[0047] It should be noted that after completing the above-mentioned dispensing and focusing processes, the lens 33 to be treated can be irradiated with a dry adhesive irradiation lamp to achieve UV curing. This dry adhesive irradiation lamp can be mounted on the support platform 32 and / or the frame 1, and irradiate light towards the lens 33 to be treated on the support platform 32; wherein, as... Figure 1 As shown, and in conjunction with references Figure 3 In this embodiment, a plurality of first dry adhesive irradiation lamps 6 are specifically provided on the frame 1. These first dry adhesive irradiation lamps 6 can be set on the frame 1 by means of an arc-shaped support plate 62 and can move along the arc direction of the arc-shaped support plate 62 to adjust their irradiation direction. At the same time, in this embodiment, a plurality of second dry adhesive irradiation lamps 7 are also specifically provided on the support platform 32.

[0048] The aforementioned plurality of first dry adhesive irradiation lamps 6 and plurality of second dry adhesive irradiation lamps 7 are all arranged around the lens 33 to be processed, and the first light beam 61 and the second light beam 71 emitted by the plurality of first dry adhesive irradiation lamps 6 and the plurality of second dry adhesive irradiation lamps 7 are all focused onto the lens 33 to be processed on the support platform 32 to irradiate it. Thus, after the above-mentioned adhesive has cured, the operator can unload the lens after the adhesive has been applied and the focus has been adjusted, completing the lens processing procedure.

[0049] Accordingly, in order to better control the dispensing and focusing processes of the aforementioned automatic lens dispensing and focusing machine, in this embodiment, as follows: Figure 1 As shown, the control mechanism 5 of the automatic lens dispensing and focusing machine includes a processor and a switch control button. The processor and the switch control button can be specifically installed on the frame 1, and the switch control button is communicatively connected to the processor so that when the operator presses the switch control button, an on or off control command is sent to the processor, thereby using the processor to control the operation of the dispensing mechanism 2, the transmission mechanism 3, and the focusing mechanism 4.

[0050] Of course, in practical applications, in order to facilitate understanding of the processing progress, a display screen 8 can also be set on the frame 1. The display screen 8 is connected to the processor of the control mechanism 5, and the working data of the automatic lens dispensing and focusing machine can be displayed visually via the display screen 8.

[0051] In summary, the automatic lens dispensing and focusing machine designed in this utility model optimizes its structure so that both the dispensing mechanism 2 and the focusing mechanism 4 are installed on the frame. By utilizing the transmission mechanism 3, the lens 33 to be processed can switch between the dispensing station of the dispensing mechanism 2 and the corresponding focusing station of the focusing mechanism 4, thereby completing the lens dispensing and focusing processes in one step. The operator does not need to switch the workbench to the focusing machine for focusing after lens dispensing, which can greatly improve production efficiency and product quality. It has good prospects for promotion and application value.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
