Description

Technical Field

[0001] This application belongs to the technical field of photomask production equipment, specifically relating to a photomask crystal box opening device. Background Technology

[0002] In semiconductor manufacturing and photolithography, photomasks, as key components carrying precise patterns, directly affect the transfer accuracy of lithographic patterns due to their surface cleanliness and structural integrity, playing a decisive role in the yield of the final product. To prevent photomasks from being contaminated by dust, physical impacts, or chemical corrosion during storage, transportation, and handling, the industry typically uses specially designed crystal boxes to seal and protect them. These crystal boxes generally consist of a box body and a lid, which are rotatably connected to the box body and equipped with a locking mechanism to reliably lock the lid and box together, ensuring that the photomask is in a completely sealed protective environment when not in use.

[0003] In the process of using photomasks, the photomask needs to be removed from the crystal box through an opening operation. Currently, opening the crystal box mostly relies on manual operation or simple tools: When operating manually, the operator needs to manually release the locking mechanism and then flip the lid to open the box. This process carries the risk of the lid shaking or colliding with the photomask due to uneven operating force, and manual contact may introduce contaminants, affecting the cleanliness of the photomask. Moreover, the opening efficiency is low. When using simple opening devices, existing opening devices are often simple in structure, only able to achieve the single function of unlocking or flipping. Multiple tool changes or adjustments to the operating steps are required, which not only reduces the opening efficiency but also easily leads to problems such as incomplete unlocking of the locking mechanism and deviation of the lid flipping angle, which may cause potential damage to the crystal box or photomask and affect the opening efficiency. Utility Model Content

[0004] This application provides a mask-based crystal box opening device to solve the technical problems of low opening efficiency and easy contamination of the mask during manual opening of traditional crystal boxes.

[0005] The technical solution adopted in this application is as follows:

[0006] A mask-printed crystal box opening device is provided for opening a crystal box. The crystal box includes a box body and a lid rotatably connected to the box body. The lid has a locking part, which has a locking position for locking the lid to the box body and a disengaging position for unlocking the lid. The opening device includes a body and an unlocking module installed on the body: the unlocking module includes a first driving component and an unlocking part, the first driving component being able to drive the unlocking part to move along the unlocking direction to switch the locking part from the locking position to the disengaging position; and a top cover flipping module, the top cover flipping module including a second driving component and a suction part, the second driving component being able to drive the suction part to move to pick up the lid and drive the suction part to move to rotate the lid relative to the box body.

[0007] The box-opening device described in this application also includes the following additional technical features:

[0008] The body has a placement surface, and a placement area for placing the crystal box is formed above the placement surface. The body has an installation cavity below the placement surface, and the installation cavity has a clearance opening that communicates with the placement area. The unlocking module is installed in the installation cavity, and the unlocking part extends out of the installation cavity through the clearance opening.

[0009] The first driving assembly includes a first driving motor, a first transmission mechanism, and a lead screw mechanism. The lead screw mechanism includes a transmission nut and a transmission screw. The transmission screw is connected to the unlocking part, and the transmission nut is fixedly connected to the first driving motor. The first driving motor drives the unlocking part to move in the unlocking direction in sequence through the first transmission mechanism and the lead screw mechanism.

[0010] The first transmission mechanism includes a first transmission wheel, a second transmission wheel, and a first transmission belt sleeved on the first transmission wheel and the second transmission wheel. The first transmission wheel is fixedly connected to the output end of the first drive motor, and the second transmission wheel is fixedly connected to the end of the transmission screw. The first drive motor drives the first transmission wheel to rotate so as to drive the second transmission wheel to rotate synchronously.

[0011] The unlocking part includes a mounting base and an unlocking fork mounted on the top of the mounting base. The unlocking fork is used to move the locking part. The unlocking module also includes a guide rail. The bottom of the mounting base is provided with a guide groove that is adapted to the guide rail. The guide rail is located inside the guide groove. The unlocking part moves along the unlocking direction through the sliding cooperation between the guide rail and the guide groove.

[0012] The top cover flipping module also includes a rotating structure rotatably connected to the body. The suction part is installed on the rotating structure. The second driving component drives the rotating structure to rotate relative to the body. The suction part moves relative to the body as the rotating structure rotates and drives the cover to rotate relative to the box.

[0013] The rotating structure includes two spaced-apart rotating arms and mounting arms connected to the rotating arms respectively. The suction part is mounted on the mounting arm. The rotating arm and the mounting arm cooperate to form a clearance space. When the suction part sucks up the cover, the cover is located within the clearance space.

[0014] The top cover flipping module also includes a second drive motor and a second transmission mechanism. The second drive motor drives the rotating structure to rotate relative to the body through the second transmission mechanism.

[0015] The second transmission mechanism includes a third transmission wheel, a fourth transmission wheel, and a second transmission belt sleeved on the third and fourth transmission wheels. The third transmission wheel is fixedly connected to the output end of the second drive motor, and the fourth transmission wheel is fixedly connected to the rotating structure via a rotating shaft. The second drive motor drives the third transmission wheel to rotate so as to drive the fourth transmission wheel to rotate synchronously.

[0016] The suction unit includes multiple electric suction cups, and the box opening device also includes a solenoid valve installed on the body, which controls the suction and release of the electric suction cups.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The box-opening device of this application includes an unlocking module and a top cover flipping module. The unlocking module is used to drive the locking part to switch from the locked position to the separated position, thereby unlocking the lid and the box. The unlocking part is driven by a first driving component, replacing manual unlocking and avoiding problems such as incomplete unlocking or over-operation of the locking part due to uneven operating force, ensuring that the locking part can accurately switch from the locked position to the separated position. The top cover flipping module drives the suction part to adsorb the lid and rotate it through a second driving component, replacing the unstable operation of manual flipping. The flipping trajectory and speed of the lid are controlled by mechanical transmission, effectively preventing the lid from shaking or colliding with the box or mask, structurally ensuring the structural integrity and surface cleanliness of the mask.

[0019] Furthermore, the modular design of the unlocking module and the top cover flipping module enhances the controllability and reliability of the operation, reducing the interference of human factors in the opening process. Manual operation is prone to affecting the quality of opening due to differences in personnel skill and fatigue. This device, however, achieves standardized operation through a mechanical structure. The parameters of the unlocking and flipping actions can be precisely set through the drive components, ensuring consistency in each opening operation. This reduces the risk of crystal box damage or mask contamination due to human error, providing a stable and reliable equipment guarantee for the safe handling of the mask, and meeting the high cleanliness and safety requirements of the semiconductor manufacturing industry for handling precision components.

[0020] In summary, the box opening device of this application integrates the unlocking module and the top cover flipping module to realize the integrated operation of the crystal box opening process, which improves the box opening efficiency. For continuous operation production lines, it can be used with upstream and downstream box loading and unloading units to open crystal boxes in batches, which greatly simplifies the box opening process and significantly improves the continuity of operation and box opening efficiency. It is especially suitable for semiconductor manufacturing scenarios with high production cycle requirements.

[0021] 2. By incorporating a placement surface and a mounting cavity beneath the main body, along with a clearance opening communicating with the placement area, an integrated mounting space is provided for the unlocking module. This structural design conceals the unlocking module beneath the placement surface, significantly reducing its interference with the crystal case placed on the surface. This substantially improves the overall compactness of the equipment, facilitating a miniaturized layout of the unlocking device and saving space in semiconductor manufacturing workshops. Simultaneously, the clearance opening ensures precise extension of the unlocking part and engagement with the locking part, reducing ineffective movement of the unlocking part, shortening the time for a single unlocking operation, and further improving unlocking efficiency. Furthermore, the mounting cavity provides a sealed protection for the unlocking module, effectively preventing external dust and impurities from entering the drive components, ensuring long-term stable operation of the unlocking module, and reducing equipment maintenance frequency.

[0039] like Figures 1 to 3 As shown, a mask-printed crystal box opening device is used to open a crystal box. The crystal box includes a box body and a lid rotatably connected to the box body. The lid is provided with a locking part, which has a locking position for locking the lid to the box body and a separation position for unlocking the lid. The opening device includes a body 1 and an unlocking module 2 installed on the body 1. The unlocking module 2 includes a first driving component and an unlocking part 21. The first driving component drives the unlocking part 21 to move along the unlocking direction to drive the locking part to switch from the locking position to the separation position. The upper cover flipping module 3 includes a second driving component and a suction part 31. The second driving component drives the suction part 31 to move to suction the lid and drives the suction part 31 to move to drive the lid to rotate relative to the box body.

[0040] The box-opening device of this application includes an unlocking module 2 and a lid-flipping module 3. The unlocking module 2 is used to drive the locking part to switch from the locked position to the separated position, thereby unlocking the lid and the box. It also drives the unlocking part 21 to move via a first driving component, replacing manual unlocking and avoiding problems such as incomplete unlocking or over-operation of the locking part due to uneven operating force, ensuring that the locking part can accurately switch from the locked position to the separated position. The lid-flipping module 3 drives the suction part 31 to adsorb the lid and rotate it via a second driving component, replacing the unstable operation of manual flipping. It controls the flipping trajectory and speed of the lid through mechanical transmission, effectively preventing the lid from shaking, colliding with the box or the mask, and structurally ensuring the structural integrity and surface cleanliness of the mask. Furthermore, the modular design of the unlocking module 2 and the lid-flipping module 3 enhances the controllability and reliability of the operation, reducing the interference of human factors in the box-opening process. Manual operation is susceptible to variations in skill levels and fatigue, which can affect the quality of box opening. This device, however, achieves standardized operation through a mechanical structure. The parameters for unlocking and flipping actions can be precisely set via the drive component, ensuring consistency in each opening operation. This reduces the risk of crystal box damage or mask contamination due to human error, providing a stable and reliable guarantee for the safe handling of masks. It meets the high cleanliness and safety requirements for handling precision components in the semiconductor manufacturing industry. In summary, the box opening device of this application, by integrating the unlocking module 2 and the top cover flipping module 3, achieves integrated operation of the crystal box opening process, improving opening efficiency. For continuous production lines, it can be combined with upstream and downstream box loading and unloading units for batch opening of crystal boxes, significantly simplifying the opening process and greatly improving operational continuity and opening efficiency. It is particularly suitable for scenarios in the semiconductor manufacturing industry with high production cycle requirements.

[0041] Specifically, the locking part switches between the locked position and the unlocked position in a horizontal direction, and the unlocking part 21 moves in a horizontal direction to drive the locking part to move.

[0042] As a preferred embodiment of this application, such as Figure 1 As shown, the body 1 has a placement surface 111, and a placement area 4 for placing a crystal box is formed above the placement surface 111. The body 1 has an installation cavity 12 below the placement surface 111. The installation cavity 12 has a clearance opening that communicates with the placement area 4. The unlocking module 2 is installed in the installation cavity 12, and the unlocking part 21 extends out of the installation cavity 12 through the clearance opening.

[0043] Specifically, the body 1 includes a bottom plate, side plates and a top plate 11. The bottom plate, side plates and top plate 11 cooperate to form an installation cavity 12. An avoidance opening is opened in the top plate 11, and the placement surface 111 is constructed as part of the top plate 11.

[0044] By providing a placement surface 111 and a mounting cavity 12 below it on the body 1, and opening a clearance opening communicating with the placement area 4, an integrated installation space is provided for the unlocking module 2. This structural design allows the unlocking module 2 to be hidden below the placement surface 111, significantly reducing the interference of the unlocking module 2 on the crystal box placed on the placement surface 111, significantly improving the overall compactness of the equipment, facilitating the miniaturization of the box opening device, and saving space resources in the semiconductor production workshop. At the same time, the clearance opening ensures that the unlocking part 21 can extend precisely and cooperate with the locking part, reducing the invalid movement stroke of the unlocking part 21, shortening the time of a single unlocking operation, and further improving the box opening efficiency. In addition, the mounting cavity 12 forms a closed protection for the unlocking module 2, which can effectively prevent external dust and impurities from entering the driving components, ensuring the long-term stable operation of the unlocking module 2 and reducing the frequency of equipment maintenance.

[0045] As a preferred embodiment of this application, such as Figure 2 As shown, the first drive assembly includes a first drive motor 22, a first transmission mechanism, and a lead screw mechanism. The lead screw mechanism includes a transmission nut 26 and a transmission screw 27. The transmission screw 27 is connected to the unlocking part 21, and the transmission nut 26 is fixedly connected to the first drive motor 22. The first drive motor 22 drives the unlocking part 21 to move in the unlocking direction through the first transmission mechanism and the lead screw mechanism in sequence.

[0046] The first drive motor 22 is a servo motor. The unlocking part 21 is provided with a pin hole, and the end of the transmission screw 27 is provided with a positioning pin. The transmission screw 27 and the unlocking part 21 achieve circumferential positioning through the cooperation of the positioning pin and the pin hole. The transmission screw 27 drives the unlocking part 21 to move linearly in the horizontal direction without causing the unlocking part 21 to rotate.

[0047] The lead screw mechanism achieves linear transmission through the cooperation of the transmission nut 26 and the transmission screw 27, possessing high motion accuracy and position control capability. Furthermore, the travel of the unlocking part 21 along the unlocking direction can be precisely adjusted via the lead screw parameters, ensuring that the locking part can be accurately driven to the separation position. This avoids problems such as incomplete unlocking or over-driving due to insufficient drive precision, significantly improving the accuracy of the unlocking operation. Simultaneously, the lead screw mechanism has high transmission efficiency and smooth operation, reducing impact and vibration during the unlocking process, minimizing mechanical wear on the crystal box's locking part, and extending the crystal box's service life.

[0048] As a preferred embodiment of this implementation, such as Figure 2As shown, the first transmission mechanism includes a first transmission wheel 23, a second transmission wheel 24, and a first transmission belt 25 sleeved on the first transmission wheel 23 and the second transmission wheel 24. The first transmission wheel 23 is fixedly connected to the output end of the first drive motor 22, and the second transmission wheel 24 is fixedly connected to the end of the transmission screw 27. The first drive motor 22 drives the first transmission wheel 23 to rotate so as to drive the second transmission wheel 24 to rotate synchronously.

[0049] The first transmission wheel 23 and the second transmission wheel 24 are connected by the first transmission belt 25, which features low operating noise and smooth transmission. This reduces the probability of transmission vibration during the driving process being transmitted to the unlocking part 21, thereby reducing the probability of misalignment between the unlocking part 21 and the locking part due to vibration and ensuring the stability of the unlocking action. The buffering characteristics of the belt drive can also effectively absorb the impact force during the drive, reducing the mechanical load on the first drive motor 22 and the lead screw mechanism, and extending the service life of the drive components. At the same time, the belt drive structure is easy to install and debug, and the clearance between the transmission wheel and the belt can be flexibly adjusted, facilitating precise control of the transmission ratio.

[0050] Preferably, such as Figure 2 As shown, the unlocking part 21 includes a mounting base 211 and an unlocking fork 212 mounted on the top of the mounting base 211. The unlocking fork 212 is used to move the locking part. The unlocking module 2 also includes a guide rail 5. The bottom of the mounting base 211 is provided with a guide groove that is adapted to the guide rail 5. The guide rail 5 is located inside the guide groove. The unlocking part 21 moves along the unlocking direction through the sliding cooperation between the guide rail 5 and the guide groove.

[0051] The mounting base 211 of the unlocking part 21 is a metal block, and the top is fixed with an unlocking fork 212 by screws. The locking part is a block-shaped structure that partially protrudes from the cover. The unlocking fork 212 has a slot in the middle, and the part of the locking part that protrudes from the cover is located in the slot. The number of unlocking parts 21 is not limited, and they can be as follows: Figure 2 Two are shown, corresponding to the two locking parts on the cover.

[0052] By providing a mounting base 211 and an unlocking fork 212 on top of the unlocking part 21, and configuring a sliding fit structure between the guide rail 5 and the guide groove, precise guidance is provided for the movement of the unlocking part 21. The fit between the guide rail 5 and the groove restricts the degree of freedom of movement of the unlocking part 21, ensuring that the unlocking part 21 only moves in a straight line along the unlocking direction, avoiding deviation or shaking during movement, and ensuring that the unlocking fork 212 is always aligned with the action point of the locking part, significantly improving the accuracy of the unlocking operation. In addition, the modular design of the unlocking fork 212 facilitates replacement according to the locking part structure of different crystal boxes, improving the versatility of the device, eliminating the need to replace the entire unlocking module 2 due to changes in crystal box specifications, and reducing equipment adaptation costs.

[0053] As a preferred embodiment of this application, such as Figure 1 , Figure 3 As shown, the top cover flipping module 3 also includes a rotating structure 6 rotatably connected to the body 1. The suction part 31 is installed on the rotating structure 6. The second drive component drives the rotating structure 6 to rotate relative to the body 1. The suction part 31 moves relative to the body 1 as the rotating structure 6 rotates and drives the cover to rotate relative to the box.

[0054] The rotating structure 6 is rotatably connected to the body 1 via a rotating shaft (not marked in the figure). Bearings are fitted at both ends of the rotating shaft to reduce rotational friction. The main body of the rotating structure 6 is a metal frame. The suction part 31 is fixed to the front end of the rotating structure 6 by bolts. When the suction part 31 abuts against the upper surface of the cover, the bottom surface of the suction part 31 is parallel to the surface of the cover. The cover and the box are rotatably connected by a hinge. The rotating shaft of the rotating structure 6 is parallel to the hinge shaft and has approximately the same height. During operation, the second drive assembly drives the rotating shaft to rotate, and the rotating structure 6 drives the suction part 31 to rotate synchronously. The cover adsorbed by the suction part 31 flips with the rotating structure 6 in a direction parallel to the hinge shaft, realizing the rotational opening of the cover relative to the box.

[0055] By setting a rotating structure 6 that is rotatably connected to the body 1 and installing the suction part 31 on the rotating structure 6, the movement trajectory of the cover flipping module 3 is made to better match the natural rotation path of the cover, ensuring that the suction part 31 can stably adsorb the cover and drive it to rotate, thus improving the reliability of the flipping operation.

[0056] As a preferred embodiment of this implementation, such as Figure 1 , Figure 3 As shown, the rotating structure 6 includes two spaced rotating arms 61 and mounting arms 62 connected to the rotating arms 61 respectively. The suction part 31 is mounted on the mounting arm 62. The rotating arm 61 and the mounting arm 62 cooperate to form a clearance space 63. When the suction part 31 sucks up the cover, the cover is located in the clearance space 63.

[0057] Specifically, the two rotating arms 61 of the rotating structure 6 are arranged in parallel and spaced apart, and are fixed perpendicularly to the rotating shaft. The mounting arm 62 is horizontally connected to the top of the two rotating arms 61, forming a "door"-shaped frame with the rotating arms 61. The width of the clearance space 63 inside the frame is greater than the width of the cover. The suction part 31 is installed in the middle of the mounting arm 62, adsorbing the central area of ​​the cover. When the cover is sucked up and flipped, the edge of the cover maintains a gap with the inside of the rotating arm 61, and the entire cover is within the clearance space 63, avoiding collision with the rotating arm 61 or the machine body 1 during the flipping process.

[0058] When the suction unit 31 adsorbs and flips the cover, the cover is located within the clearance space 63, effectively preventing interference between the cover and the rotating structure 6 or other parts of the body 1. This ensures the cover can smoothly flip to its maximum angle, facilitating subsequent mask retrieval. The frame structure reduces the weight of the rotating components while maintaining structural rigidity, lowering the load on the second drive assembly, improving the response speed of the flipping motion, shortening the time for a single flipping operation, and further improving opening efficiency. In addition, the spaced rotating arms 61 enhance structural stability, making the suction unit 31 more evenly stressed when adsorbing the cover, avoiding the risk of collision caused by the cover shifting due to stress.

[0059] As another preferred embodiment of this implementation, such as Figure 3 As shown, the top cover flipping module 3 also includes a second drive motor 32 and a second transmission mechanism. The second drive motor 32 drives the rotating structure 6 to rotate relative to the body 1 through the second transmission mechanism.

[0060] The combined drive mechanism of the second drive motor 32 and the second transmission mechanism makes the rotational power source of the rotating structure 6 more specific and controllable. Compared with traditional manual tilting or direct drive by a single motor, this modular drive structure allows for precise control of rotational speed and angle through parameter adjustment of the second drive motor 32.

[0061] As a preferred example in this embodiment, such as Figure 3 As shown, the second transmission mechanism includes a third transmission wheel 33, a fourth transmission wheel 34, and a second transmission belt 35 sleeved on the third transmission wheel 33 and the fourth transmission wheel 34. The third transmission wheel 33 is fixedly connected to the output end of the second drive motor 32, and the fourth transmission wheel 34 is fixedly connected to the rotating structure 6 through a rotating shaft. The second drive motor 32 drives the third transmission wheel 33 to rotate so as to drive the fourth transmission wheel 34 to rotate synchronously.

[0062] The second transmission mechanism is designed as a belt drive structure, which has the advantages of smooth operation and low noise. It can reduce the vibration transmitted to the cover during the flipping process, reduce the probability of the adsorption force of the suction part 31 decreasing due to vibration, and ensure that the cover is always stably adsorbed during the flipping process.

[0063] As a preferred embodiment of this application, such as Figure 1 , Figure 3 As shown, the suction unit 31 includes multiple electric suction cups 311, and the box opening device also includes a solenoid valve 7 installed on the body 1. The solenoid valve 7 controls the suction and release of the electric suction cups 311.

[0064] The electric suction cup 311 of the suction unit 31 is a circular suction cup with a flat bottom surface that fits the surface of the cover. Multiple electric suction cups 311 are distributed at intervals corresponding to the central area of ​​the cover. When the electric suction cup 311 is powered on, the internal air is drawn out, generating negative pressure to adsorb the cover; when the power is turned off, the suction disappears and the cover is released.

[0065] An electric suction cup 311 is used as the suction unit 31, and the suction and release are controlled by a solenoid valve 7, which features fast response speed and stable suction force. The on and off control of the solenoid valve 7 can realize the instantaneous suction and release of the suction unit 31, shorten the operation time of the lid suction and release, and improve the opening efficiency.
