Description

Technical Field

[0001] The utility model relates to the technical field of automatic masking, and specifically, to an automatic masking device for an optical coating substrate. Background Technique

[0002] Optical coating technology is to precisely deposit one or more extremely thin metal or dielectric material films on the surface of optical parts. It can not only significantly change the interaction between light and matter, but also endow optical components with a series of specific optical properties such as anti-reflection, enhanced transmission, spectral selective reflection or transmission, beam separation, color correction, polarization control, etc. This process has extremely strict requirements for the thickness, uniformity, refractive index and stress control of the film, which directly determines the performance and application effect of the final optical device. With the rapid development of focal plane detection technology, especially the wide application of high-sensitivity cameras, astronomical observation instruments, medical imaging systems and various optoelectronic sensors, unprecedented high standards have been put forward for the packaging technology of optical components and the performance indicators of thin film filters. For example, a focal plane array (FPA) requires highly integrated, miniaturized and high-resolution optical filters to achieve precise screening and efficient transmission of optical signals in a specific wavelength range. Although the traditional manual masking production method can achieve a certain degree of customization and flexibility, its limitations become more obvious when facing large-scale production, high-precision requirements and complex optical designs. Manual operation is not only inefficient and difficult to meet the needs of large-scale production, but also prone to introducing human errors, affecting the uniformity and repeatability of coating, resulting in product quality fluctuations. In addition, high labor costs and long production cycles are also important factors restricting industrial upgrading. Content of the Utility Model

[0003] The utility model provides an automatic masking device for an optical coating substrate, which solves the problems in the related technology that manual masking is not only inefficient but also increases labor costs.

[0004] The technical solution of the utility model is as follows:

[0005] An automatic masking device for an optical coating substrate, characterized by comprising a negative film and a plurality of films adhered to the negative film, and further comprising:

[0006] A frame having a first supporting surface for supporting the negative film;

[0007] An adsorbing member movably arranged on the frame and located above the supporting surface for adsorbing the film;

[0008] A clamping member movably arranged on the frame, and after the clamping member moves, it is used for clamping the negative film and driving the negative film to move.

[0009] As a further technical solution, the two sides of the frame are provided with a first guiding groove and a second guiding groove. The second guiding groove has a clamping section and a relaxing section that are sequentially communicated. The clamping member includes:

[0010] A first moving member movably arranged in the first guiding groove;

[0011] A second moving member movably arranged in the second guiding groove. After the second moving member moves to the clamping section, the first moving member and the second moving member approach each other to clamp the negative film. After the second moving member moves to the relaxing section, the first moving member and the second moving member move away from each other to relax the negative film.

[0012] As a further technical solution, both the first guiding groove and the second guiding groove are annular grooves.

[0013] As a further technical solution, both the first moving member and the second moving member include:

[0014] A clamping unit, with both ends correspondingly and movably arranged in the first guiding groove or the second guiding groove;

[0015] Two rotating wheels, correspondingly rotatably arranged at both ends of the clamping unit. The clamping unit is movably arranged in the first guiding groove or the second guiding groove through the rotating wheels.

[0016] As a further technical solution, it further includes:

[0017] A synchronous belt, circulating and conveying in the first guiding groove or the second guiding groove. The clamping unit is arranged on the synchronous belt.

[0018] As a further technical solution, the clamping unit is a connecting rod.

[0019] As a further technical solution, it further includes:

[0020] A first elastic member, with both ends correspondingly hinged on the two clamping units. The first elastic member is used to provide a force for the two clamping units to approach each other.

[0021] As a further technical solution, the frame further has a material receiving cavity, and the material receiving cavity is located below the relaxing section.

[0022] As a further technical solution, the frame further has a second supporting surface and a third supporting surface. The second supporting surface is used to support the mold, and the third supporting surface is used to support the substrate. After the adsorbing member moves, it drives the substrate and the film into the mold.

[0023] As a further technical solution, it further includes:

[0024] The rotating plates, several in number, are rotatably arranged at intervals on the frame.

[0025] The material receiving member is arranged on the frame and is located below the rotating plates. After the rotating plates are rotated to the horizontal state, it is used to support the semi-finished products. After the rotating plates are rotated to the vertical state, the semi-finished products slide onto the material receiving member.

[0026] The working principle and beneficial effects of the present utility model are as follows:

[0027] In the present utility model, the frame serves as the main supporting structure of the entire device and is made of high-strength lightweight materials (such as aluminum alloy or carbon fiber composite materials), ensuring the stability and durability of the device. The surface of the frame is treated with anti-static to reduce potential damage to the optical coating substrate. A flat first supporting surface is provided on the frame, and the first supporting surface is designed with minute textures or coatings to increase the friction when placing the negative film, prevent sliding, and at the same time maintain non-destructive contact with the negative film. The adsorbing member is controlled by a pneumatic or electric system and can move along a predetermined path above the frame. The surface of the adsorbing member is made of a soft and traceless material to ensure that no physical damage or marks are caused to the product during adsorption. The clamping member can move horizontally, vertically, and perform up-and-down lifting actions on the frame. After the clamping member moves, it cooperates with the adsorbing member to separate the film from the negative film, achieving the effect that the adsorbing member only adsorbs the film.

[0028] The entire operation process is controlled by a computer program to achieve an automated process. First, the movement and adsorption actions of the adsorbing member are controlled to remove the film from the negative film while the clamping member moves the negative film away. This method reduces the errors and damage risks of manual operations through automation, ensuring high precision and consistency in the processing of optical coating substrates. To further enhance the safety of the operation, the device may also be integrated with sensors and monitoring cameras to real-time monitor the working states of the adsorbing member and the clamping member, as well as the conditions of the negative film and the film. Once an abnormality is detected, the operation is immediately stopped or an alarm is issued, ensuring the reliability of the entire processing process and the integrity of the substrate.

[0037] Referring to Figures 1 to 3 , for the first embodiment of the present invention, there is provided

[0038] An automatic masking device for optical coating substrates, which is characterized in that it includes a negative film and a plurality of films adhered to the negative film, and further includes:

[0039] A frame 100 having a first supporting surface 110, and the first supporting surface 110 is used to support the negative film;

[0040] An adsorbing member 200 movably arranged on the frame 100 and located above the supporting surface, and the adsorbing member 200 is used to adsorb the film;

[0041] The clamping member 300 is movably arranged on the rack 100. After the clamping member 300 moves, it is used to clamp the negative film and drive the negative film to move.

[0042] In this embodiment, the rack 100 serves as the main supporting structure of the entire device and is made of high-strength lightweight materials (such as aluminum alloy or carbon fiber composite material), ensuring the stability and durability of the device. The surface of the rack 100 is treated with anti-static to reduce potential damage to the optical coating substrate. A flat first supporting surface 110 is provided on the rack 100. The first supporting surface 110 is designed with minute textures or coatings to increase the friction when placing the negative film, prevent sliding, and at the same time maintain non-destructive contact with the negative film. The adsorbing member 200 is controlled by a pneumatic or electric system and can move along a predetermined path above the rack 100. The surface of the adsorbing member 200 is made of a soft and markless material to ensure that no physical damage or marks are caused to the product during adsorption. The clamping member 300 can move horizontally, vertically, and perform up-and-down lifting actions on the rack 100. After the clamping member 300 moves, it cooperates with the adsorbing member 200 to separate the film from the negative film, achieving the effect that only the film is adsorbed by the adsorbing member 200.

[0043] The entire operation process is controlled by a computer program to achieve an automated process. First, the movement and adsorption actions of the adsorbing member 200 are controlled. While the film is removed from the negative film, the clamping member 300 moves the negative film away. This method reduces the errors and damage risks of manual operations through automation, ensuring the high precision and consistency of optical coating substrate processing. To further enhance the safety of the operation, the device may also be integrated with sensors and monitoring cameras to continuously monitor the working states of the adsorbing member 200 and the clamping member 300, as well as the conditions of the negative film and the film. Once an abnormality is detected, the operation is immediately stopped or an alarm is issued, ensuring the reliability of the entire processing process and the integrity of the substrate.

[0044] In summary, this embodiment realizes the efficient and safe processing of the optical coating substrate.

[0045] Furthermore, the two sides of the rack 100 are provided with a first guiding groove 120 and a second guiding groove 130. The second guiding groove 130 has a clamping section 131 and a relaxing section 132 that are sequentially connected. The clamping member 300 includes:

[0046] A first moving member 310 movably arranged in the first guiding groove 120;

[0047] A second moving member 320 movably arranged in the second guiding groove 130. After the second moving member 320 moves to the clamping section 131, the first moving member 310 and the second moving member 320 approach each other to clamp the negative film. After the second moving member 320 moves to the relaxing section 132, the first moving member 310 and the second moving member 320 move away from each other to relax the negative film.

[0048] In this embodiment, there are a first guiding groove 120 and a second guiding groove 130 on both sides of the rack 100. The first guiding groove 120 and the second guiding groove 130 provide guidance for the movement of the clamping member 300, ensure the smooth movement of the moving member therein, reduce friction and deviation, and improve the stability and repeat positioning accuracy of the entire system. The second guiding groove 130 is specially designed as a continuous structure with a clamping section 131 and a relaxation section 132, so that when the second moving member 320 moves to the clamping section 131, it can cooperate with the first moving member 310 to form a clamping force on the negative film; when the second moving member 320 moves to the relaxation section 132, the first moving member 310 and the second moving member 320 are separated, facilitating the placement or removal of the negative film, and improving the flexibility and efficiency of the operation. The first moving member 310 is installed in the first guiding groove 120, and its movement is controlled by a driving device. The second moving member 320 is located in the second guiding groove 130. The surfaces of the moving member and its contact with the negative film are made of materials with low friction coefficient and wear resistance to reduce physical damage to the negative film and reduce wear during long-term use. Lubrication structures may be installed inside the first guiding groove 120 and the second guiding groove 130 to further reduce the movement resistance and extend the service life. To ensure the safety of the operation, sensors and limit switches may also be integrated in the system to monitor the position and movement state of the moving member and prevent equipment damage caused by incorrect operations. At the same time, through integration with the central control system, precise monitoring and automatic control of the entire clamping and moving process can be achieved, improving the intelligent level of the operation. In summary, this embodiment not only realizes the clamping and relaxation control of the negative film, but also improves the flexibility, safety and operation efficiency of the entire automatic masking device.

[0049] Furthermore, both the first guiding groove 120 and the second guiding groove 130 are annular grooves.

[0050] In this embodiment, different from the traditional linear guiding groove, the first guiding groove 120 and the second guiding groove 130 in this embodiment are both designed as annular structures, surrounding both sides of the rack 100. The design of the annular groove not only improves the space utilization efficiency of the entire device, realizes a wider operation range within the limited space of the rack 100, but also improves the clamping efficiency of the clamping member 300 and realizes the cyclic clamping of the clamping member 300.

[0051] Furthermore, both the first moving member 310 and the second moving member 320 include:

[0052] A clamping unit 330, with both ends respectively corresponding to and movably arranged in the first guiding groove 120 or the second guiding groove 130;

[0053] The rotating wheels 340 are provided at both ends of the clamping unit 330 in a corresponding rotating manner. The clamping unit 330 is movably arranged in the first guiding groove 120 or the second guiding groove 130 through the rotating wheels 340.

[0054] In this embodiment, the clamping units 330 are respectively located in the first guiding groove 120 and the second guiding groove 130. Rotating wheels 340 are installed at both ends of each clamping unit 330. These rotating wheels 340 are made of wear-resistant materials to ensure tight fit and low-friction rolling with the walls of the first guiding groove 120 and the second guiding groove 130. The rotating design of the rotating wheels 340 reduces the direct friction between the clamping unit 330 and the first guiding groove 120 or the second guiding groove 130.

[0055] Furthermore, it further includes:

[0056] A synchronous belt is circulated and conveyed in the first guiding groove 120 or the second guiding groove 130, and the clamping unit 330 is arranged on the synchronous belt.

[0057] In this embodiment, a high-performance synchronous belt is respectively circulated and laid in the first guiding groove 120 and the second guiding groove 130. The synchronous belt is made of materials with high wear resistance, low elongation rate and good flexibility, such as polyurethane or rubber-reinforced fiber materials, ensuring the stability and reliability of long-term operation. Both ends of the clamping unit 330 are fixed on the synchronous belt, and the rotating wheels 340 are still rotatably arranged at both ends of the clamping unit 330. After the synchronous belt moves, it drives the clamping unit 330 to move. During the movement of the clamping unit 330, it drives the rotating wheels 340 to rotate. The synchronous belt is located in the middle of the clamping unit 330 and the rotating wheels 340. Since both sides of the frame 100 are provided with the first guiding groove 120 and the second guiding groove 130, there are several synchronous belts, which are correspondingly circulated and wound in the corresponding first guiding groove 120 or the second guiding groove 130. The synchronous belt can be driven by a driving member to move, so as to realize the movement of the clamping unit 330. The driving cost is reduced.

[0058] Furthermore, the clamping unit 330 is a connecting rod.

[0059] In this embodiment, in order to ensure that the clamping unit 330 always clamps the negative film during movement and can assist in separating the film from the negative film when driving the negative film to move, after the clamping unit 330 clamps the negative film in this embodiment, it first moves downward. One end of the negative film with the film overlaps on the first supporting surface 110, and the end separated from the negative film moves downward, causing a fold angle to appear on the negative film itself. When this fold angle moves to the position of the film as the negative film moves, the negative film separates from the film, and the auxiliary suction member 200 adsorbs the film. In this embodiment, the clamping unit 330 is designed in a cylindrical structure. When the clamping unit 330 moves to the clamping section, the two cylinders approach each other to clamp the negative film. When the clamping unit 330 moves along the first guiding groove 120 and the second guiding groove 130, the angle between it and the negative film may change. However, in this embodiment, no matter which position the clamping unit 330 moves to, it can clamp the negative film. At the same time, in order not to affect the formation of the fold angle, when the clamping section becomes horizontally arranged in this embodiment, a rotating roller is designed at the fold angle of the clamping section, and the negative film is closely attached to the rotating roller to ensure that the fold angle on the negative film does not disappear.

[0060] Further, it further includes:

[0061] The first elastic member 400, with two ends respectively and pivotally connected to the two clamping units 330, and the first elastic member 400 is used to provide a force for the two clamping units 330 to approach each other.

[0062] In this embodiment, in order to increase the clamping force on the negative film, several first elastic members 400 are designed between the two clamping units 330. The first elastic members 400 are always in a stretched state. When the synchronous belt undergoes slight deformation and the clamping force between the two clamping units becomes weaker, the first elastic members 400 can provide a continuous clamping force to ensure that the negative film is firmly clamped.

[0063] Further, the frame 100 further has a material receiving cavity 140, and the material receiving cavity 140 is located below the relaxation section 132.

[0064] In this embodiment, after the film on the negative film is removed, the negative film becomes waste material. In order to collect the waste negative film, a material receiving cavity 140 is designed below the relaxation section 132 in this solution. When the film on the negative film is completely removed, the starting end of the negative film moves towards the relaxation section 132. After moving to the relaxation section 132, the clamping unit no longer clamps the negative film, and the negative film drops into the lower material receiving cavity 140.

[0065] Further, the frame 100 further has a second supporting surface 150 and a third supporting surface 160. The second supporting surface 150 is used to support the mold, and the third supporting surface 160 is used to support the substrate. After the suction member 200 moves, it drives the substrate and the film into the mold.

[0066] In this embodiment, in addition to the original first supporting surface 110 for placing the negative film, the rack 100 is newly added with a second supporting surface 150 and a third supporting surface 160. The second supporting surface 150 is designed specifically for molds and can stably carry various molds. The third supporting surface 160 is used to directly support the optical coating substrate to be processed. After the adsorbing member 200 moves and adsorbs the film, it drives the film into the mold. Subsequently, the adsorbing member 200 also drives the electrode sheet to be processed into the mold. After being driven into the mold, the adsorbing member 200 closes the adsorption and presses the substrate and the film downward, so that the substrate and the film adhere together. Subsequently, the adsorption is opened, and the semi-finished product formed by the substrate and the film is moved to the next process.

[0067] To achieve the above precise movement and docking operations, the entire system integrates a highly intelligent control system, including but not limited to a PLC controller, a sensor network, a servo drive system, etc. These systems are responsible for monitoring the movement path, speed, and force of the adsorbing member 200, and at the same time ensuring the precise docking of the mold with the substrate and the film, realizing an efficient and synchronous operation process.

[0068] In summary, this embodiment significantly enhances the functionality and flexibility of the optical coating substrate automatic masking device.

[0069] Furthermore, it also includes:

[0070] Rotating plates 500, several of them are arranged on the rack 100 at intervals and rotate;

[0071] A material receiving member 600 is arranged on the rack 100 and is located below the rotating plates 500. After the rotating plates 500 rotate to the horizontal state, it is used to support the semi-finished product. After the rotating plates 500 rotate to the vertical state, the semi-finished product slides onto the material receiving member 600.

[0072] In this embodiment, a number of rotating plates 500 are spaced apart on the frame 100. These rotating plates 500 are designed as rotatable structures and can freely rotate on the frame 100 around their own central axes. The material of the rotating plates 500 will not scratch the semi-finished products. Each rotating plate 500 is equipped with a driving device (such as a stepper motor or a servo motor) and a limit sensor, and its rotation to the horizontal or vertical state is precisely controlled by a control system. When in the horizontal state, the rotating plate 500 serves as a working platform for temporarily supporting the semi-finished products removed from the mold; when in the vertical state, it serves as a release mechanism, enabling the semi-finished products to slide down onto the receiving member 600 below by gravity. In order to reduce the cost of the receiving member 600, in this embodiment, when receiving materials, the semi-finished products need to be placed vertically, and a number of vertically placed semi-finished products are arranged in sequence on the receiving member 600, increasing the number of semi-finished products received by the receiving member 600. The receiving member 600 is located below the frame 100 and is matched with the position of the rotating plate 500 for receiving the semi-finished products sliding down from the rotating plate 500. This embodiment not only optimizes the processing flow of the semi-finished products, improves the level of production automation, but also ensures the efficiency and safety of the operation and reduces manual intervention.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
