Description

Technical Field

[0001] The utility model relates to the field of lens detection instruments, in particular to a lens outer diameter measuring device and an automatic detection system. Background Art

[0002] Aspheric precision molded finished lenses are extremely important and have extremely high quality requirements among optical products. The lenses need to be accurately measured for appearance and size. At present, the measurement of size is generally done by manual measurement. Not only is the size obtained by the test inaccurate, the error rate is high, and the quality cannot be guaranteed, but manual measurement requires the use of a micrometer to contact the lens, which is inefficient and easy to scratch the lens.

[0003] Due to the urgent need to solve the above problems, some intelligent detection instruments have appeared on the market. For example, the Chinese invention patent with publication number CN110953958A discloses a lens size detection device and method, which detects the size of the lens with the help of a measuring plate that can easily place the lens and an automated infrared device. It is suitable for simple spot checks on the mirror surface size, but the detection efficiency is not very high.

This test method cannot accurately detect curved surfaces, bosses and transparent lenses.

When the entire material tray 11 is full, the lower material bin servo tray closing Y module 6033 works, driving the hook tray plate and the full material tray 11 to move along the Y direction, and sending the hook tray plate and the material tray 11 into the full tray recovery basket 6031. The full tray recovery basket servo lifting module 6032 drives the full tray recovery basket 6031 to move up a certain distance, so that the material tray 11 falls on the partition bar, and the lower material bin servo tray closing Y module 6033 returns, taking the hook tray plate out of the full tray recovery basket 6031, and the hook tray plate can take over the next empty material tray 11.

When the upper bin pushing assembly 302 or the lower bin pushing assembly 601 is working, the pushing cylinder 3022 extends to push out the pushing plate 3025, and the pushing plate 3025 pushes the material tray 11 from the hook plate to the material passing plate 7, and then pushes it to the hook plate on the upper bin servo recovery Y module 3033 or the lower bin servo closing Y module 6033; at the same time, the guide rod 3023 plays a guiding role, making the operation of the pushing plate 3025 more stable.

The positioning cylinder 3014 is arranged to limit the position of the material tray 11. The hook section 3016 and the positioning cylinder 3014 respectively limit the two ends of the material tray 11, which plays a stabilizing role on the one hand and facilitates positioning on the other hand, so that after the control host 10 calculates, the servo loading Z module 403 and the servo unloading Z module 405 can accurately reach the top of the lens to be taken.

[0065] See also Fig.12 The utility model also provides an upper frame 8 and a lower frame 9 to surround and protect the automatic detection system from dust. The upper frame 8 and the lower frame 9 are respectively provided with doors to facilitate manual operation and maintenance. The control host 10 is connected to a human-machine interaction panel and is provided outside the upper frame 8 and the lower frame 9.

[0066] The workflow of this automatic detection system:

[0067] (1) In the initial state: the loading basket 3011 is filled with the tray 11, and the tray 11 is full of lenses to be tested; the empty tray loading basket 6021 is filled with empty trays 11; the empty tray recovery basket 3031 and the full tray recovery basket 6031 are in an empty warehouse state, and there are also empty spaces for the unqualified tray 11;

[0068] (2) Loading:

[0069] Retrieving materials and empty trays: the positioning cylinder 3014 is in a retracted state; the loading bin servo loading Y module 3013 works, driving the hook plate to move along the Y direction, and sending the hook plate to the specified position inside the loading basket 3011. The loading basket servo lifting module 3012 drives the loading basket 3011 to move down a certain distance, and the material tray 11 falls on the hook plate. The loading bin servo loading Y module 3013 returns, and takes the hook plate and the material tray 11 out of the loading basket 3011. The positioning cylinder 3014 extends, and the positioning cylinder 3014 and the hook section 3016 jointly fix the material tray 1 1; at the same time, the lower bin servo tray placing Y module 6023 works, driving the hook tray plate to move along the Y direction, and sending the hook tray plate to the specified position inside the empty tray loading basket 6021, and the empty tray loading basket servo lifting module 6022 drives the empty tray loading basket 6021 to move down a certain distance, so that the empty tray falls on the hook tray plate, and the lower bin servo tray placing Y module 6023 returns, and takes the hook tray plate and the empty tray out of the empty tray loading basket 6021, and the positioning cylinder 3014 extends, and the positioning cylinder 3014 and the hook segment 3016 jointly fix the position of the empty tray;

[0070] Pushing materials and empty trays: the pushing cylinder 3022 extends, the positioning cylinder 3014 contracts, and the pushing plate 3025 of the upper bin pushing assembly 302 pushes the full tray 11 from the upper bin servo loading Y module 3013 to the feeding plate 7, and then pushes it to the upper bin servo recovery Y module 3033; at the same time, the pushing plate 3025 of the lower bin pushing assembly 601 pushes the empty tray 11 from the lower bin servo tray placement Y module 6023 to the feeding plate 7, and then pushes it to the lower bin servo tray closing Y module 6033;

[0071] Unloading: The X-axis double-actuator linear motor 404 drives the loading Z module to move to the top of the material hole of the loading bin servo recovery Y module 3033 loading tray 11. The loading Z module moving end descends. After sucking the lens to be tested, the actuator works and floats in front of the camera 501. After the camera 501 takes a picture, it sends the picture result to the control host 10. The loading Z module moving end rises and arrives above the test bench 206 with the actuator. The placement position is adjusted according to the analysis result taken by the angle detection device, and the lens to be tested is placed in the center of the test bench 206 as much as possible.

[0072] (3) Testing (while continuing to take materials): the control host 10 controls the first servo lifting module 203 to work, adjusts the lens to a suitable height, and controls the first spectral confocal sensor 202 and the second spectral confocal sensor 204 to perform testing. The test results are fed back to the control host 10 and recorded. During the test, the control host 10 controls the rotary stepping motor 205 to work, thereby performing tests at multiple angles.

[0073] During the test, the feeding Z module is driven by the mover to move to the top of the next material hole of the feeding tray 11 of the feeding bin servo recovery Y module 3033;

[0074] (4) Unloading (discharging at the same time): After the test is completed, the unloading Z module is driven by the actuator to move to the top of the test table 206, and after sucking the tested lens, the placement position is determined according to whether the test result is qualified or unqualified. If it is a qualified product, the actuator drives the servo unloading Z module 405 to move to the top of the material hole 11 of the material tray 11 of the servo closing Y module 6033 of the unloading bin to unload the material; if it is an unqualified product, the actuator drives the servo unloading Z module 405 to move to the top of the material hole 11 of the unqualified material tray to unload the material; at the same time, the loading Z module repeats the unloading step once;

[0075] When all the lenses to be tested on the first material tray 11 are taken out, steps (2), (3), and (4) are repeated to load and test until the test is completed.

[0076] Any utility model creation is to create something new through the application and combination of existing technologies. There are infinite possibilities for the primary and secondary judgments of many technical issues and the application and combination of many technical means. The above is only a description of the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this field, several improvements can be made without departing from the principles of the utility model. These improvements should also be regarded as the protection scope of the utility model.
