Description

Technical Field

[0001] The present invention relates to the technical field of optical glass manufacturing, and more particularly to an optical glass splitting and film laminating machine and its usage method. Background Art

[0002] Under the current development trend, the market's functional requirements for electronic products such as mobile phones, tablets, and smart panels are becoming more diverse. Especially in the aspect of cameras, requirements such as good shooting, light sensing, and depth focusing have led to the popularization of triple cameras and quadruple cameras. Cameras have become an essential configuration on electronic products such as mobile phones. The existing optical glass used for cameras has gradually shifted from grinding wheel cutting to laser cutting. That is, the general processing technological process of existing optical glass is: glass raw material → glass middle piece → laser cutting → tempering - screen printing → electroplating NCVM → screen printing bottom covering → plating screen printing surface AR → plating surface AF → splitting → film laminating → full inspection → packaging.

[0003] Currently, in the processing of existing optical glass, after the printing and coating of the entire glass are completed, the splitting process is usually carried out manually. Even when using an automatic method for splitting, traditional mechanical and contact - type hard splitting methods are adopted, such as using a splitting stamping jig for processing splitting, etc. However, in the commonly used traditional contact - type hard splitting production process, the following problems usually exist:

[0004] 1. Since the upper cover plate in the splitting jig directly presses against the surface of the glass monomer, it is easy to cause defects such as surface scratches and abrasions on the product during splitting.

[0005] 2. Affected by the processing accuracy of the splitting jig and the mechanical movement accuracy, there is an uneven force during splitting, which easily leads to defects such as product edge chipping and glass frame cracking. Moreover, when the glass frame is damaged, the broken glass will scratch and damage the product, resulting in the scrapping of all products on the entire glass middle piece.

[0006] 3. Because the uneven force is amplified when splitting multiple glass middle pieces simultaneously, it is more likely to cause damage to the glass frame. Therefore, the existing splitting jigs can only split in the form of a single glass middle piece, resulting in low efficiency.

[0007] 4. When using hard splitting, at the moment when the glass monomer separates from the glass frame, the upper and lower cover plates in the splitting jig will collide at high speed, causing vibrations, increasing the fatigue of the splitting jig, and resulting in a low service life of the splitting jig.

[0008] Therefore, how to ensure the processing efficiency while solving the technical problems of product defects existing in traditional contact - type hard splitting production has not yet proposed an effective solution. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention provides an optical glass crack coating machine and a method of using the same, which adopts a one-mold multi-cavity pneumatic flexible crack processing method in which compressed air is introduced into the closed space formed by the glass middle piece, the accommodating groove and the cavity to make the pressure in the closed space uniform, thereby ensuring the processing efficiency while improving the yield of the crack processing.

[0067] More specifically, the roller set includes a third roller 431, a fourth roller 432, a fifth roller 433, a sixth roller 437, an eighth roller 439 fixedly installed on the support plate 415, and a seventh roller 438 fixedly installed on the bottom plate 11 through a support column. Among them, the fourth roller 432 and the sixth roller 437 are arranged opposite to each other vertically, the eighth roller 439 and the fifth roller 433 are arranged opposite to each other vertically, the third roller 431 is arranged above the fourth roller 432 and the eighth roller 439, the synchronous belt 436 is in transmission connection with the fifth roller 433, the sixth roller 437 and the idler pulley 435, and the tensioning pulley 434 is used to adjust the tension of the synchronous belt 436 so that the fourth roller 432 and the sixth roller 437 and the eighth roller 439 and the fifth roller 433 keep running synchronously.

[0068] Before splitting and laminating the optical glass chips in the present invention, the lower film material 421 needs to be bypassed around the seventh roller 438, passed under the lower cover plate 35, and pulled to the front ends of the fourth roller 432 and the sixth roller 437; then the upper film material 411 is bypassed around the third roller 431 and pulled to the front ends of the fourth roller 432 and the sixth roller 437; then the conveying drive assembly is controlled by the control mechanism to pull the upper film material 411 and the lower film material 421 to between the fourth roller 432 and the sixth roller 437 and between the fifth roller 433 and the eighth roller 439. During the process of splitting and laminating the chips, when the chip monomer 503 falls on the lower film material 421, the conveying drive assembly is controlled by the control mechanism to pull the lower film material 421 with the chip monomer 503 attached forward, and at the same time pull the upper film material 411, so that the upper film material 411 and the lower film material 421 pass through between the fourth roller 432 and the sixth roller 437 and between the fifth roller 433 and the eighth roller 439 at the same time, until the upper film material 411 covers the chip monomer 503, and at this time, a single chip splitting and laminating process can be completed.

[0069] As an embodiment of the present invention, the laminating mechanism 40 further includes an adaptive adjustment component, which includes a limit plate 441, an adjustment spring 442 and a support block 443. The support blocks 443 are installed at both ends of the fifth roller 433 and the sixth roller 437, and the support blocks 443 are installed on the support plate 415. At the same time, the limit plate 441 is fixedly installed on the support plate 415 and directly above the support block 443, and the adjustment spring 442 is installed between the limit plate 441 and the support block 443, so that not only the fourth roller 432 and the sixth roller 437 and the fifth roller 433 and the eighth roller 439 can be kept in a pressed state, but also the gap between the fourth roller 432 and the sixth roller 437 and the fifth roller 433 and the eighth roller 439 can be automatically adjusted according to the thickness of the split monomer 503.

[0070] In summary, the optical glass crack laminating machine of the present invention has the following beneficial effects:

[0071] 1. The pneumatic flexible splitter has no hard contact with the product surface during the splitting process, thus avoiding defects such as crushing and scratching. At the same time, the product surface is subjected to uniform and stable force, thus avoiding defects such as fragmentation and edge collapse, and the operation is stable with high yield.

[0072] 2. By introducing compressed air into the closed space formed by the glass middle piece, the containing groove and the cavity, the pressure in the closed space can be made uniform. When the upper plane of the glass frame is subjected to downward pressure, the lower plane of the glass frame will be subjected to upward pressure from the lower cover plate because the lower cover plate can be against the bottom plate. That is, during the splitting process, the glass frame is always in a compressed state and will not break, thus ensuring the product yield.

[0073] 3. By arranging a plurality of receiving grooves adapted to the glass middle sheets on the lower cover plate, one mold with multiple cavities is realized, that is, the splitting operation of multiple glass middle sheets can be realized at one time, thereby improving efficiency.

[0074] In addition, the present invention also provides a method for using an optical glass crack laminating machine in an embodiment, which specifically includes the following steps:

[0075] S1, placing the lower cover plate with four glass middle sheets on the support plate;

[0076] S2, start the split film laminating machine through the start button in the control mechanism, at this time, the cylinder can drive the upper cover plate downward so that the bottom surface of the upper cover plate is pressed against the top surface of the lower cover plate, and at the same time drive the lower cover plate and the supporting plate downward until the bottom surface of the lower cover plate is against the bottom plate and the lower film material;

[0077] S3. Through the control mechanism, compressed air is introduced into the closed space formed by the middle glass sheet, the accommodation groove and the cavity on the upper cover plate through the air holes on the upper cover plate. After the pressure in the closed space reaches the set value and is kept for the set time, the glass monomers on the middle glass sheet can be split into split monomers, and the split monomers can fall onto the lower film material through the chip dropping holes on the lower cover plate;

[0078] S4. Through the control mechanism, the supply of compressed air into the closed space is stopped and the upper cover plate is driven to move upward by the air cylinder, so that the upper cover plate is away from the lower cover plate and the supporting plate. At this time, the reset spring placed between the supporting plate and the bottom plate drives the supporting plate and the lower cover plate to reset under the action of the elastic restoring force, so that the lower cover plate is away from the lower film material and the bottom plate;

[0079] S5. Through the control mechanism, the drive motor in the transmission drive assembly is controlled to drive the third roller, the fourth roller, the fifth roller, the sixth roller, the seventh roller and the eighth roller; multiple rollers pull the lower film material with the split monomers forward at a set speed, and at the same time pull the upper film material, so that the upper film material and the lower film material pass through between the fourth roller and the sixth roller and between the fifth roller and the eighth roller at the same time. After running a set distance, the upper film material can be covered on the split monomers to complete the continuous processing of single-chip splitting and film covering.

[0080] In this embodiment, after the continuous processing of single-chip splitting and film covering is completed, only the lower cover plate needs to be replaced to complete the loading and unloading; at the same time, for different products, only the lower cover plate needs to be replaced, and there is no need to replace the entire optical glass splitting and film covering machine, which further saves the equipment manufacturing cost and improves the production efficiency. After replacing the lower cover plate, repeating the above steps can perform continuous operations.

[0081] Further, before step S1, the following steps are also included:

[0082] S01. The lower film material in the film covering mechanism is bypassed around the seventh roller, passed under the lower cover plate in the chip splitting mechanism, and pulled to the front of the fourth roller and the sixth roller;

[0083] S02. The upper film material in the film covering mechanism is bypassed around the third roller and pulled to the front of the fourth roller and the sixth roller;

[0084] S03. The transmission drive assembly in the film covering mechanism is controlled through the jog button in the control mechanism to pull the upper film material and the lower film material to between the fourth roller and the sixth roller and between the fifth roller and the eighth roller;

[0085] S04. The compressed air pressure introduced into the closed space formed by the middle glass sheet, the accommodation groove and the cavity, the pressure holding time of the compressed air, the single-film covering running distance and the film covering running speed are respectively adjusted through the pressure setting button, the pressure holding time setting button, the film covering running distance setting button and the film covering running speed adjusting knob in the control mechanism.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
