Description

Technical Field

[0001] This utility model relates to the technical field of polarizing mirror processing equipment, specifically to an automatic loading and unloading device for fully automatic polarizing mirror dicing. Background Technology

[0002] A polarizing filter is an optical element with polarizing filtering function, widely used in eyeglasses, displays, photographic equipment, and other fields. In the production of polarizing filters, dicing is one of the key processing steps, requiring the precise cutting of a whole sheet of polarizing filter substrate to a predetermined size.

[0003] Currently, some polarizing lens dicing processes still rely on manual loading and unloading, where the polarizing lenses to be processed are placed on the dicing platform manually, and then manually removed and collected after processing. This method has the following drawbacks: First, manual operation is inefficient and cannot meet the needs of large-scale production; second, positioning deviations are prone to occur when manually placing polarizing lenses, affecting dicing accuracy; third, polarizing lenses are relatively brittle, and scratches and damage are easily caused during manual handling, reducing product qualification rates; and fourth, long-term repetitive operations increase the intensity of manual labor and the company's labor costs.

[0004] Existing automated loading and unloading devices suffer from problems such as complex structure, poor coordination of components, and limited adaptability, making it difficult to reliably achieve full automation of the entire process of polarizing mirrors from storage, calibration, loading, processing to unloading. Therefore, there is an urgent need to design an automated loading and unloading device for fully automated polarizing mirror dicing to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic loading and unloading device for fully automatic polarizing lens dicing, so as to solve the technical problems of low efficiency, poor accuracy, easy damage to products, and poor coordination of existing automation devices in the processing of polarizing lens dicing by manual loading and unloading.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic loading and unloading device for fully automatic polarizing lens dicing, comprising a polarizing lens cassette shaft, a polarizing lens correction shaft, a polarizing lens picking shaft, a polarizing lens transfer shaft, loading and unloading cylinders, a loading vacuum suction cup, unloading and unloading cylinders, and an unloading vacuum suction cup; the polarizing lens cassette shaft is used to store polarizing lenses to be processed and polarizing lenses after processing; the polarizing lens correction shaft is used to correct the position of the polarizing lenses to be processed; the polarizing lens transfer shaft is used to realize the transfer of the polarizing lenses to be processed between the cassette shaft and the correction shaft; the loading and unloading cylinders are connected to the loading vacuum suction cup and are used to transfer the corrected polarizing lenses to be processed to the dicing platform; the unloading and unloading cylinders are connected to the unloading vacuum suction cup and are used to remove the polarizing lenses after dicing from the dicing platform; the polarizing lens picking shaft is used to transfer the processed polarizing lenses removed by the unloading vacuum suction cup back to the polarizing lens cassette shaft.

[0007] A further improvement of this utility model is that the polarizer correction axis is equipped with a positioning sensor, which is used to detect the placement position of the polarizer to be processed and to provide feedback correction signals.

[0008] A further improvement of this utility model is that: the polarizer housing shaft is provided with layered partitions, each partition is used to independently place a single polarizer, and the housing shaft can rotate along its own axis to realize the switching and conveying of different layers of polarizers.

[0009] A further improvement of this utility model is that: both the rotating shaft and the material picking shaft of the polarizer are equipped with an angle adjustment mechanism to adjust the conveying posture of the polarizer and adapt to the positional connection between the calibration shaft, the dicing platform and the material box shaft.

[0010] 1. This utility model achieves full automation of the polarizing mirror process from storage, calibration, loading, processing to unloading through the coordinated design of each shaft, cylinder and suction cup. No manual intervention is required, which greatly improves processing efficiency, reduces labor costs and is suitable for large-scale production.

[0011] 2. The polarizer correction axis, in conjunction with the positioning sensor, can accurately correct the position of the polarizer, avoiding positioning deviations caused by manual placement and ensuring dicing accuracy.

[0012] 3. The structure is reasonably designed and the operation of each component is highly coordinated. The layered design and rotatable structure of the material box shaft, as well as the angle adjustment mechanism of the transfer shaft and the picking shaft, ensure the smooth transfer of polarizing mirrors between processes. It has strong adaptability and can meet the processing needs of polarizing mirrors of different specifications.

[0013] 4. During the processing, the pre-correction of the workpiece to be processed and the dicing of the current workpiece are carried out in parallel, which shortens the processing cycle of a single piece and further improves production efficiency. Attached Figure Description

Detailed Implementation

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0016] The purpose of this utility model, as provided in this embodiment, is to address the technical problems existing in the prior art and provide... An automatic loading and unloading device for fully automatic polarizer dicing, such as Figure 1 As shown, the assembly includes a polarizing mirror material box shaft 1, a polarizing mirror correction shaft 2, a polarizing mirror picking shaft 3, a polarizing mirror transfer shaft 4, a loading cylinder 5, a loading vacuum suction cup 6, a unloading cylinder 7, and an unloading vacuum suction cup 8. The polarizing mirror material box shaft 1 has 10 layers of partitions 9 inside, with a spacing of 5mm between each layer, which is suitable for standard-sized polarizing mirrors. Each layer independently holds a single polarizing mirror 12. The polarizing mirror material box shaft 1 is driven by a stepper motor to rotate along its own axis, with a rotation angle accuracy of ±0.5°, ensuring accurate layer switching.

[0017] The polarizer correction shaft 2 is equipped with a laser positioning sensor 10 with a detection accuracy of ≤ ±0.01mm. The fine-tuning stroke of the polarizer correction shaft 2 is ±2mm. Position correction is achieved by servo motor drive with a response time of ≤0.5s.

[0018] Both the rotating shaft 4 and the angle adjustment mechanism 11 on the polarizing mirror and the material picking shaft 3 are electric rotary tables with an adjustment angle range of 0-360° and an adjustment accuracy of ±0.1°, ensuring that the polarizing mirror 12 is adapted to the conveying posture.

[0019] The suction surfaces of the loading vacuum suction cup 6 and the unloading vacuum suction cup 8 are made of silicone. The stroke of the loading cylinder 5 and the unloading cylinder 7 is 100mm, and the moving speed can be adjusted within the range of 50mm / s-200mm / s. The positioning accuracy is ≤±0.02mm.

[0020] 1. In the initial state, 50 polarizing mirrors to be processed are placed in the 1-50 layered partitions 9 of the polarizing mirror material box shaft 1; 2. After the control system is started, the polarizing mirror rotating shaft 4 rotates to the first layer of the material box shaft 1, adsorbs the polarizing mirror to be processed, adjusts its posture through the angle adjustment mechanism 11, and is then conveyed to the polarizing mirror correction shaft 2. 3. Positioning sensor 10 detects the position of the polarizer and sends a feedback signal to the control system. The polarizer correction axis 2 is then finely adjusted to complete the positioning correction. 4. The loading cylinder 5 drives the loading vacuum suction cup 6 to move down and adsorb the polarizing mirror 12 with an adsorption pressure of -20kPa. Then the cylinder moves up and moves above the dicing platform 12 to place the polarizing mirror in the preset position. 5. The laser starts the scribing process, and at the same time, the polarizer rotation axis 4 takes out the second polarizer to be processed and transfers it to the polarizer correction axis 2 to complete the pre-correction; 6. After the first polarizing lens is diced, the loading mechanism conveys the second polarizing lens to the dicing platform, and the unloading mechanism picks up and removes the first processed polarizing lens 12. 7. The polarizing mirror feeding shaft 3 conveys the processed polarizing mirror 12 back to the 51st layer (reserved layer) of the material box shaft 1. 8. Repeat the above steps until all 50 polarizing lenses are processed. No manual intervention is required throughout the process. The processing cycle is shortened by 40% compared to traditional equipment, and the product yield is increased to over 99.5%.

[0021] The above are merely preferred embodiments of this utility model, but do not limit the patent scope of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model's specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
