Description

Technical Field

[0001] The invention relates to the technical field of glass coating, and discloses a film layer joint coating processing method, in particular to a film layer joint coating processing method for a glass window used for light detection and distance measurement. Background Art

[0002] For magnetron sputtering coating products with multiple layers and different patterns, such as glass windows used for light detection and ranging in LiDAR (Laser Radar) systems, it is necessary to coat the glass surface multiple times so that a black film, an ITO (Indium Tin Oxide) film and an anti-reflective film are formed on the glass surface in sequence to meet the product usage requirements. At present, the industry fixes the glass product to be coated on a hanging plate, and transports the hanging plate and the glass as a whole to the coating chamber of the coating machine for coating. If the size of the coating pattern needs to be controlled, a shielding cover plate needs to be manually placed on the surface of the hanging plate, and the shielding cover plate is fixed to the surface of the hanging plate with screws. The size of the coating pattern is controlled by the size of the shielding window on the shielding cover plate. In the case of adopting the above method, when each film layer has different pattern size requirements, it is necessary to stop the coating machine after completing one layer of coating, remove the hanging plate, add or replace the shielding block, and then transport the hanging plate after the shielding block is replaced to the coating chamber, and perform the coating operation again. Thus, for products such as LiDAR glass windows that require three layers of coating with different patterns, the coating hanging plate needs to be removed and the blocking block needs to be replaced twice, and a total of three independent coating operations are required to complete the three-layer coating of the product. The three coating operations take a total of about 6.5 hours, which is long, energy-intensive, and inefficient. Moreover, since the coating operation is carried out in a vacuum environment, the surface cleanliness of the product is required to be high. Taking out the product and replacing the hanging plate during the operation is prone to introduce dust or dirt. The re-entry of the product into the coating operation has a greater impact on the cleanliness, which ultimately affects the coating yield of the product. Summary of the invention

[0003] Based on this, it is necessary to provide a film layer joint plating processing method with high coating efficiency and coating yield to address the above-mentioned shortcomings.

[0009] S5, stop the coating machine, control the air pressure in the conveying channel and the storage box by the vacuum device to be the same as that in the coating chamber, open the partition door, and remove the shielding hanging plate on the coating hanging plate by the first manipulator mechanism, and put the shielding hanging plate back into the storage box;

[0010] S6. Repeat steps S4-S5 according to the number of layers to be coated on the product until all layers are coated, and then take out the coated hanging board and the product.

The second manipulator mechanism is used to fix the coating hanging plates delivered from the feed end of the coating machine at the mounting positions.

[0012] In one of the embodiments, a plurality of hooks arranged along a circular path to form the installation position are provided on the ring side of the coating rotor, and hanging holes for passing the hooks are opened on the coating hanging plate.

[0013] In one of the embodiments, a limiting notch is provided on the end of the coating hanging plate facing away from the hanging hole, and a turntable is rotatably arranged on the bottom plate of the coating machine. A plurality of limiting blocks distributed along a circular path are arranged on the edge of the turntable, and the limiting blocks include a first limiting portion for inserting into the limiting notch and a second limiting portion located on a side of the first limiting portion facing away from the transmission channel and fixedly connected to the first limiting portion, and the second limiting portion is used to abut against the side of the coating hanging plate.

[0014] In one of the embodiments, the coated hanging plate is provided with a plurality of installation grooves for embedding glass sheets in a one-to-one correspondence, exhaust holes are provided on the bottom surfaces of the installation grooves, and a plurality of card slots are provided on the coated hanging plate; a plurality of coating windows corresponding to the installation grooves are provided on the shielding hanging plate, and a plurality of elastic card blocks corresponding to the card slots are provided on the shielding hanging plate, the width of the elastic card block is smaller than the width of the card slot, and two elastic fins are relatively arranged on both sides of the elastic card block, and the sum of the width of the two elastic fins unfolded in a natural state and the width of the elastic card block is greater than the width of the card slot.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] Please combine Figure 1-7The present invention discloses a processing method for film layer joint plating with high coating efficiency and coating yield. The coating system adopted by the processing method includes a coating machine 100, a storage box 200 located next to the coating machine 100, a transmission channel 300 sealedly connected to the coating machine 100 and the storage box 200 and respectively connected to the coating chamber of the coating machine 100 and the inner cavity of the storage box 200, a partition door 400 for separating the coating chamber and the transmission channel 300, a vacuum device for controlling the air pressure in the transmission channel 300 and the storage box 200, and a control module for controlling the opening and closing of the partition door 400 and the operation of the vacuum device. At least one coating hanging board 500 for installing the glass to be coated is hung in the coating chamber, at least one shielding hanging board 600 is arranged in the storage box 200, and a first manipulator mechanism 700 for hanging the shielding hanging board 600 on the coating hanging board 500 or removing the shielding hanging board 600 from the coating hanging board 500 is arranged in the transmission channel 300, and the first manipulator mechanism 700 is electrically connected to the control module. In other words, the coating machine 100, the transmission channel 300 and the storage box 200 together form a closed chamber so as to limit the glass coating operation in the closed chamber to avoid the introduction of external dust or impurities; the transmission channel 300 is located between the coating machine 100 and the storage box 200, which is used to provide an installation area for the first manipulator mechanism 700 on the one hand, and on the other hand, it also provides a moving channel for the first manipulator mechanism 700 to transfer the shielding hanging board 600 to the coating hanging board 500 in the coating chamber.

[0029] Specifically, the processing method of this embodiment includes the following steps:

[0030] S1. Mount the glass to be coated on the coating hanging board 500, and hang the coating hanging board 500 in the coating chamber.

[0031] In the present embodiment, the installation of the glass on the coating hanging plate 500 is carried out outside the coating machine 100. After the operator installs the glass to be coated on the coating hanging plate 500, the coating hanging plate 500 with the glass is transported to the loading section of the coating machine 100, and the coating hanging plate 500 can be hung in the coating chamber manually or automatically.

[0032] S2, close the partition door 400 and start the coating machine 100 to perform coating operation on the glass.

[0033] In step S2, the coating operation is directly performed on the glass surface, that is, the first film layer (black film) is coated on the glass surface. In this solution, the coating operation on the product surface is performed by vacuum sputtering coating. Specifically, by controlling the vacuum condition in the coating chamber, the evaporator of the coating machine 100 heats the coating material, so that the coating material sublimates and forms evaporated particles. The evaporated particles form an evaporated particle flow under the action of the electric field in the coating chamber, and are ejected toward the glass, and are deposited on the glass surface to form a solid film (i.e., black film).

[0034] During the coating operation, the coating chamber can be separated from the transmission channel 300 and the inner cavity of the storage box 200 by pre-closing the partition door 400 between the coating chamber and the transmission channel 300 during the coating operation, thereby preventing evaporated particles during the coating operation from entering the transmission channel 300 or the storage box 200, thereby preventing the product surface from having an insufficient coating effect.

[0035] S3, stop the coating machine 100, control the air pressure in the conveying channel 300 and the storage box 200 by the vacuum device to be the same as that in the coating chamber, and open the partition door 400.

[0036] In this embodiment, before the partition door 400 is opened, the air pressure in the transmission channel 300 and the storage box 200 is adjusted by a vacuum device so that the air pressure in the transmission channel 300, the inner cavity of the storage box 200 and the coating chamber is kept consistent, that is, the transmission channel 300, the inner cavity of the storage box 200 and the coating chamber are all in a vacuum condition, which can avoid the problem of parts damage or explosion caused by the pressure difference between the coating chamber and the transmission channel 300 and the rapid impact of the gas in the transmission channel 300 on the equipment in the coating chamber, thereby ensuring the safety of the operation. By opening the partition door 400, a channel is provided for the first manipulator mechanism 700 to install the shielding hanging plate 600 on the coating hanging plate 500.

[0037] S4. The first manipulator mechanism 700 moves and grabs a shielding hanging plate 600 in the storage box 200, hangs the shielding hanging plate 600 on the coating hanging plate 500 one by one, closes the partition door 400 and starts the coating machine 100 to perform coating operation on the glass.

[0038] In this embodiment, a first manipulator mechanism 700 is used to grab and install a shielding hanging plate 600 on the coating hanging plate 500. The shielding hanging plate 600 shields the surface of the first film on the glass, thereby changing the shape of the portion to be coated on the surface of the first film, so that a second film (i.e., an ITO film) with a different pattern from the first film is coated on the surface of the first film, thereby completing the coating of the second film.

[0039] S5. Stop the coating machine 100, control the air pressure in the transfer channel 300 and the storage box 200 by the vacuum device to be the same as that in the coating chamber, open the partition door 400, and use the first manipulator mechanism 700 to remove the shielding hanging plate 600 from the coating hanging plate 500, and put the shielding hanging plate 600 back into the storage box 200.

[0040] S6. Repeat steps S4-S5 according to the number of layers to be coated on the product until all layers are coated, and then take out the coating hanging plate 500 and the product.

[0041] That is to say, in this embodiment, after the second layer of film coating is completed with the assistance of a shielding hanging plate 600, the shielding hanging plate 600 needs to be removed by the first manipulator mechanism 700. If the glass surface only needs to be coated with two layers of films with different patterns, after step S5 is completed, the coating hanging plate 500 and the product can be removed from the unloading section of the coating machine 100. If the glass surface needs to be coated with three or more film layers with different patterns, after the first shielding hanging plate 600 is removed from the coating hanging plate 500, the second shielding hanging plate 600 for shielding the second film layer on the glass is grabbed from the storage box 200 by the first robot mechanism 700, and the second shielding hanging plate 600 is fixed on the coating hanging plate 500, and the above operation is repeated to realize the coating operation of the third film layer on the glass; after the second shielding hanging plate 600 is removed from the coating hanging plate 500, the third shielding hanging plate 600 for shielding the third film layer on the glass is grabbed from the storage box 200 by the first robot mechanism 700, and the third shielding hanging plate 600 is fixed on the coating hanging plate 500, and the above operation is repeated to realize the coating operation of the fourth film layer on the glass... and so on, until the coating operation of all film layers on the glass is completed.

[0042] In this embodiment, the coating machine 100 is provided with a transparent enclosure 110, a top plate 120 fixed on the top of the enclosure 110, and a bottom plate 130 fixed on the bottom of the enclosure 110. The enclosure 110, the top plate 120 and the bottom plate 130 together form a coating chamber so that the operator can view the working conditions in the coating chamber in real time; the enclosure 110 is provided with a feed port for forming a loading section, a discharge port for forming a unloading section, and a hanging plate replacement port connected to the conveying channel 300, and movable doors electrically connected to the control module are provided at the feed port and the discharge port, and a partition door 400 is provided at the hanging plate replacement port. The bottom plate 130 is provided with slide rails at the corresponding feed port, discharge port and hanging plate replacement port, and the movable door and partition door 400 are respectively slidably embedded in the corresponding slide rails. The coating machine 100 also includes a first electric push rod electrically connected to the control module to push the movable door to slide and close or open the feed port or discharge port, and a second electric push rod electrically connected to the control module to push the partition door 400 to slide and close or open the hanging plate replacement port. In addition, the side wall of the transmission channel 300 and the inner wall of the receiving chamber are made of transparent materials, such as acrylic plates or tempered glass, so that the operator can monitor the operation status of the transmission channel 300 and the receiving box 200 in real time.

[0043] The coating machine 100 also includes a coating rotor 140 housed in the coating chamber and rotatably connected to the top plate 120 of the coating machine 100, a first drive motor 150 electrically connected to the control module and used to drive the coating rotor 140 to rotate, and a second manipulator mechanism located outside the coating chamber. The coating rotor 140 is provided with a plurality of mounting positions arranged in a ring and used to mount the coating hanging plates 500 one by one. The second manipulator mechanism is used to fix the coating hanging plates 500 delivered from the feeding end of the coating machine 100 at the mounting positions. In this way, the coating hanging plates 500 can be hung one by one at the mounting positions on the coating rotor 140 by the second manipulator mechanism, so as to reduce labor costs and improve the installation efficiency of the coating hanging plates 500. Preferably, the second manipulator mechanism is a six-axis manipulator or a four-axis manipulator, and the second manipulator mechanism is adjacent to the loading section of the coating machine 100. In addition, in this embodiment, by providing a coating rotor 140 and a first driving motor 150, the coating machine 100 can load multiple coating hanging plates 500 at a time, and multiple pieces of glass can be loaded on one coating hanging plate 500, which significantly improves the coating efficiency of the product. The first driving motor 150 is used to drive the coating rotor 140 to rotate, so that the glass on the coating hanging plates 500 at various positions on the coating rotor 140 can contact with the evaporated particles generated by the vacuum sputtering action, so as to ensure the uniformity of the thickness of the coating film layer.

[0044] It should be noted that, in the present embodiment, the coating machine 100 also includes a heater electrically connected to the control module and used to heat the coating chamber. In this way, when the first layer of film (black film) is coated on the glass surface, the coating chamber can be heated at the same time to reach the temperature required for coating the second layer of film (ITO film). There is no need to preheat the glass additionally, thereby shortening the operation time.

[0045] Furthermore, the ring side of the coating rotor 140 is provided with a plurality of hooks 141 arranged along a ring path to form a mounting position, and the coating hanging plate 500 is provided with a hanging hole 510 for passing the hooks 141. In this way, the second manipulator mechanism grabs the coating hanging plate 500 and sleeves the hooks 141 on the coating hanging plate 500 onto the hooks 141, so that the coating hooks 141 can be suspended and installed. In order to prevent the coating hanging plate 500 from shaking during the rotation of the coating rotor 140, in this embodiment, a limiting notch 520 is provided on the end of the coating hanging plate 500 that is away from the hanging hole 510, and a turntable 160 is rotatably provided on the bottom plate 130 of the coating machine 100. The edge of the turntable 160 is provided with a plurality of limiting blocks 170 distributed along a circular path. The limiting blocks 170 include a first limiting portion for inserting into the limiting notch 520 and a second limiting portion located on a side of the first limiting portion that is away from the transmission channel 300 and fixedly connected to the first limiting portion. The second limiting portion is used to abut against the side of the coating hanging plate 500. During the rotation of the coating rotor 140, the turntable 160 rotates synchronously driven by the coating hanging plate 500. It can also be understood that the vertical cross-section of the limit block 170 is an L-shaped structure, and the first limit portion abuts against the inner surface of the limit notch 520 to limit the rotation of the coating hanging plate 500 relative to the turntable 160; the second limit portion is used to limit the radial movement of the coating hanging plate 500 along the turntable 160, so that during the process of the coating hanging plate 500 and the shielding hanging plate 600 being installed in coordination, the coating hanging plate 500 is limited so as to fix the shielding hanging plate 600 on the coating hanging plate 500.

[0046] In one embodiment, a plurality of mounting grooves 530 for correspondingly embedding glass sheets are provided on the coated hanging plate 500, so that multiple pieces of glass can be clamped on the coated hanging plate 500 at one time, and the glass can be fixed in the mounting groove 530 of the coated hanging plate 500 by bonding. An exhaust hole 540 is provided on the bottom surface of the mounting groove 530, so that the gas in the mounting groove 530 can be discharged through the exhaust hole 540 during the glass installation process, so as to reduce the difficulty of glass installation. A plurality of card slots 550 are provided on the coated hanging plate 500, and the card slots 550 are used to provide a mounting portion for the shielding hanging plate 600 on the coated hanging plate 500. A plurality of coating windows 610 corresponding to each mounting groove 530 are provided on the shielding hanging plate 600, and the coating windows 610 are used to define the shape of the film layer to be coated on the glass surface, and the glass is positioned by the edge of the coating window 610. The shielding hanging plate 600 is provided with a plurality of elastic blocks 620 for correspondingly engaging in the slots 550. In the present embodiment, the width of the elastic blocks 620 is smaller than the width of the slots 550, and two elastic fins are arranged opposite to each other on both sides of the elastic blocks 620. The sum of the width of the two elastic fins unfolded in a natural state and the width of the elastic blocks 620 is larger than the width of the slots 550. In this way, during the assembly of the shielding hanging plate 600 and the coating hanging plate 500, it is only necessary to align the elastic blocks 620 with the slots 550 one by one and push the shielding hanging plate 600 toward the coating hanging plate 500. During this process, the elastic fins are squeezed by the inner wall of the slots 550 to produce deformation and press against the inner wall of the slots 550, thereby realizing a firm connection between the shielding hanging plate 600 and the coating hanging plate 500, preventing the shielding hanging plate 600 from falling off the coating hanging plate 500 during the rotation of the coating rotor 140, so as to ensure the reliability of the coating operation.

[0047] In order to realize the installation of the shielding hanging plate 600 in the storage box 200, in one embodiment, at least one hanging rod 210 fixedly connected to the inner wall of the storage box 200 and extending along the length direction of the storage box 200 is provided in the storage box 200, and the hanging rod 210 penetrates the coating window 610 of the shielding hanging plate 600 to hang the shielding hanging plate 600. Further, when the type of shielding hanging plate 600 is greater than one, different types of shielding hanging plates 600 are arranged side by side, and each type of shielding hanging plate 600 has an operating surface corresponding to the transmission channel 300 and contactable with the first manipulator mechanism 700. In the present embodiment, the glass surface is coated with film layers of three different patterns. Accordingly, two different shielding hanging boards 600 are provided in the storage box 200. Two hanging rods 210 are arranged side by side in the storage box 200. One end of the hanging rod 210 is fixed to the inner wall of the storage box 200, and the other end of the hanging rod 210 is suspended. In this way, the shielding hanging board 600 is hung on the hanging rod 210 via the suspended end of the hanging rod 210, and each hanging rod 210 is hung with multiple shielding hanging boards 600 of the same type, so as to facilitate the removal or replacement of the shielding hanging board 600.

[0048] The first manipulator mechanism 700 includes a second drive motor 710 fixed on the top of the transmission channel 300, a screw rod 720 extending along the length direction of the transmission channel 300 and drivingly connected to the output shaft of the second drive motor 710, a mounting block 730 sleeved on the screw rod 720 and threadedly matched with the screw rod 720, a gripping member 740 located below the mounting block 730 and capable of gripping the shielding hanging plate 600, a connecting rod 750 rotatably passed through the mounting block 730 and fixedly connected to the gripping member 740, and a third drive motor 760 fixed on the mounting block 730 and drivingly connected to the connecting rod 750. In this way, the second driving motor 710 is controlled by the control module to work, and the second driving motor 710 drives the screw rod 720 to rotate. Since the screw rod 720 is threadedly matched with the mounting block 730, during the rotation of the screw rod 720, the mounting block 730 will move along the length direction of the screw rod 720, so that the gripping member 740 approaches the shielding hanging plate 600 in the storage box 200 to grab the shielding hanging plate 600, or take the shielding hanging plate 600 out of the storage box 200. When the gripping member 740 grabs the shielding hanging plate 600 and needs to transfer the shielding hanging plate 600 from the transmission channel 300 to the coating chamber, or transfer the shielding hanging plate 600 from the coating chamber to the transmission channel 300, the control module controls the third driving motor 760 to work, so that the gripping member 740 drives the shielding hanging plate 600 to rotate to adjust the direction of the shielding hanging plate 600. In this embodiment, the gripping member 740 is a pneumatic clamp or a suction cup.

[0049] During the coating process, the glass to be coated is first fixed on the coating hanging plate 500, and the coating hanging plate 500 with the glass to be coated is transported into the coating chamber by the second manipulator mechanism and fixed on the coating rotor 140 (the partition door 400 is in a closed state at this time). When all the coating hanging plates 500 are placed on the coating rotor 140, the coating machine 100 is started to perform the coating operation of the first film layer on the product. After the first film coating is completed, the coating rotor 140 slows down and stops rotating. At this time, the vacuum device controls the inner cavity of the storage box 200 and the transmission channel 300 to be in the same vacuum state as the coating chamber. The control module controls the partition door 400 to open, and the first manipulator mechanism 700 grabs the first type of shielding hanging board 600 and fixes it on the coating hanging board 500; then the first driving motor 150 drives the coating rotor 140 to rotate one station, so that the coating hanging board 500 on another station rotates to the position corresponding to the transmission channel 300, and the first manipulator mechanism 700 grabs another shielding hanging board 600 of the same type on the same hanging rod 210 until all the coating hanging boards 500 on the coating rotor 140 are installed with the shielding hanging board 600. Then, the partition door 400 is closed, the coating machine 100 is started, and the second film coating operation is performed on the product.

[0050] After the second film layer is coated, the shielding hanging plate 600 needs to be replaced. Similarly, the partition door 400 is opened, the first manipulator mechanism 700 moves to the partition door 400 and removes the first shielding hanging plate 600 on the coating hanging plate 500 near the partition door 400, and transports the removed first shielding hanging plate 600 to the corresponding hanging rod 210 in the storage box 200 for hanging, and then removes the second shielding hanging plate 600 from another hanging rod 210, and fixes the second shielding hanging plate 600 on the coating hanging plate 500. Then, the first driving motor 150 controls the coating rotor 140 to rotate, so that the next coating hanging plate 500 moves to a position close to the partition door 400, and repeats the above coating hanging plate 500 replacement operation until all coating hanging plates 500 on the coating rotor 140 are replaced, the partition door 400 is closed, and the coating machine 100 is started to perform the third film coating operation on the product. After the third film coating is completed, the first robot mechanism 700 is also required to remove the second shielding hanging plate 600 and put it back into the storage box 200 for the next furnace coating. Then the coating hanging plate 500 is taken out from the discharge port. A robot can also be set at the discharge port to take out the coating hanging plate 500 and the products that have completed the coating operation. The operator removes the products that have completed the three-layer coating from the coating hanging plate 500, and then the next furnace product coating can be prepared.

[0051] It should be noted that when three layers of films with different patterns are plated on the glass surface in a traditional manner, the glass needs to be taken out of the coating machine 100 for many times. The time parameters of the operation process are shown in the following table:

[0052]

[0053]

[0054] When using the film layer joint plating processing method of this solution to produce products of the same specifications (glass surface is sequentially plated with black film, ITO film and anti-reflection film), the time parameters of the operation process are shown in the following table:

[0055]

[0056] It can be seen that compared with the current solution that requires taking out the coating hanging plate 500 multiple times, the operation time of the film layer joint plating processing method of this solution is significantly less than the solution that requires taking out the coating hanging plate 500 multiple times, and its coating efficiency is significantly improved.

[0057] The above-mentioned film layer joint plating processing method, by setting a transmission channel 300 and a receiving box 200 for receiving a shielding hanging plate 600 on the side of the coating machine 100, when coating the glass surface with multiple layers of film, it is only necessary to open the partition door 400 between the coating cavity and the transmission channel 300, and grab the corresponding shielding hanging plate 600 in the receiving box 200 or replace the shielding hanging plate 600 through the first manipulator mechanism 700, so as to realize the plating of multiple layers of different patterned film layers on the glass surface. During the operation, there is no need to open the coating machine 100 and take out the product and the coating hanging plate 500, which reduces the operation time caused by manual operation and reduces energy consumption, thereby improving the coating operation efficiency; the multi-layer coating of the product is always carried out in a closed space, avoiding dust or dirt introduced by multiple times of taking out the product, ensuring the cleanliness of the product surface, and helping to improve the product coating yield.
