Description

Technical Field

[0001] This utility model relates to the field of optical material manufacturing technology, specifically to a glass baking apparatus. Background Technology

[0002] In the field of mobile phone optical component manufacturing, 2D and 2.5D optical materials often experience micro-bending during production due to internal stress, mismatched coefficients of thermal expansion, or material deformation, resulting in products failing flatness tests (NG). Repairing or reprocessing these defective products is a crucial step in improving yield, typically requiring the use of specialized fixtures in conjunction with high-temperature baking processes for correction. However, existing fixture technologies have significant drawbacks. Currently used fixtures and the protective high-temperature adhesives have limitations in structural design and material temperature resistance, making them unable to withstand the multiple high-temperature baking cycles required in the repair process. After repeated heat exposure, the adhesive material is prone to aging and increased fluidity, leading to adhesive overflow. The overflowing adhesive easily adheres to the delicate optical glass surface, making cleaning extremely difficult, easily causing scratches or contamination of components, and potentially even resulting in the direct scrapping of the product. Furthermore, the insufficient durability of the high-temperature adhesive necessitates frequent replacement, and its mistake-proof design during replacement is flawed, easily introducing quality risks due to operational errors, severely restricting production efficiency and the improvement of repair yield.

[0003] Therefore, existing technology has become a major bottleneck in the repair of high-precision optical components, and there is an urgent need for a new solution that can withstand multiple high-temperature processes, effectively prevent adhesive overflow, and is easy to operate and maintain.

[0018] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0019] Example 1: Figures 1-2 This invention illustrates a first embodiment of a glass baking apparatus, which includes an oven mechanism 10 and a fixing mechanism 20. The oven mechanism 10 consists of a body and a door 12, which forms a sealed baking space when closed. The fixing mechanism 20 is movably disposed inside the oven and is equipped with a clamping member 21, which pre-presses and fixes the workpiece before high-temperature baking.

[0020] In this embodiment, the oven body 11 refers to the main structure that carries the heating function, and can be composed of a metal frame and a heat insulation layer, such as a stainless steel shell combined with a ceramic fiber heat insulation layer. The movable fixing mechanism 20 refers to the displacement of the oven via a guide rail mechanism, for example, rollers at the bottom cooperating with a slide rail. The mounting position refers to the positioning area for carrying the workpiece, which can be divided into multiple independent workstations using a shelf structure. The clamping component 21 refers to the component that applies mechanical pressure, such as a screw adjusting rod combined with a pressure plate, which generates vertical pressure by tightening.

[0021] Specifically, the workpiece is placed in the mounting position of the fixing mechanism 20, and is fixed by applying pre-pressure to the workpiece through the rotating clamping member 21. After the fixing mechanism 20 is pushed into the oven, the door 12 closes to form a closed baking environment. Under high temperature, the internal stress of the workpiece is released through uniform heating, and the mechanical clamping structure maintains the stability of the workpiece shape. After baking, the fixing mechanism 20 is pulled out, and the clamping member 21 is released to remove the workpiece. The entire process does not require the use of high-temperature adhesive.

[0022] In addition, the fixing mechanism must be made of high-temperature resistant materials, such as heat-resistant steel, ceramics, or graphite, and its coefficient of thermal expansion must be close to that of the corresponding product. This is to avoid deformation or damage to the product due to shrinkage differences caused by expansion during high-temperature baking and subsequent cooling. The contact surface between the fixing mechanism and the product must be smooth, with a roughness Ra ≤ 0.8 μm, to prevent indentations or scratches from being left on the product surface.

[0023] Compared with existing technologies, traditional solutions relying on adhesive bonding have inherent drawbacks such as short material aging cycles and high risk of adhesive overflow. This solution replaces adhesive bonding with mechanical clamping, completely eliminating the source of adhesive contamination. The movable fixing mechanism 20 simplifies the workpiece loading and unloading process and avoids heat loss caused by repeatedly opening and closing the oven. The shelf-type mounting position supports simultaneous processing of multiple workpieces, significantly improving equipment utilization.

[0024] Through the above technical solution, this utility model achieves glue-free fixation of workpieces during high-temperature baking, effectively preventing glue overflow and contamination. The mechanical clamping structure maintains stable performance during multiple high-temperature cycles, extending the service life of the fixture. The movable nature of the fixing mechanism 20 simplifies the operation steps, reduces the quality risks caused by manual intervention, and improves the reliability and efficiency of optical component repair operations.

[0025] Example 2: Based on Embodiment 1, this embodiment provides a second embodiment of the glass baking apparatus to further describe the fixing mechanism 20.

[0026] In some embodiments, the fixing mechanism 20 includes a first mounting plate 22, a second mounting plate 23, a movable shelf 25, and at least one fixed shelf 24. The two ends of the movable shelf 25 and the fixed shelf 24 are fixedly connected to the first mounting plate 22 and the second mounting plate 23, respectively. The movable shelf 25 is provided with at least one first slot, and the fixed shelf 24 is provided with a second slot corresponding to the first slot. The first slot and the second slot form a mounting position. The clamping member 21 is provided on the movable shelf 25.

[0027] In this embodiment, the first mounting plate 22 and the second mounting plate 23 refer to two parallel plate-shaped components constituting the main support structure of the fixing mechanism 20. Specifically, they can be made of metal sheets cut and formed and fixedly connected by bolts, used to support the movable shelf 25 and the fixed shelf 24. The movable shelf 25 refers to a support component whose position can be adjusted relative to the fixed shelf 24. Specifically, it can be connected to the first mounting plate 22 and the second mounting plate 23 through a sliding mechanism, used to adjust the spacing of the mounting positions to accommodate workpieces of different sizes. The fixed shelf 24 refers to a support component with a fixed position, specifically fixed to the mounting plate by welding or bolts, used to cooperate with the movable shelf 25 to form a stable mounting position. The first slot and the second slot refer to groove structures respectively formed on the movable shelf 25 and the fixed shelf 24. Specifically, they can be formed into rectangular or U-shaped grooves by machining, used to jointly clamp the edges of the workpiece. The clamping member 21 refers to a mechanical component that applies pressure to fix the workpiece. Specifically, it can be a metal rod with a threaded adjustment function, which generates pressure by screwing to clamp the workpiece between the movable shelf 25 and the fixed shelf 24.

[0028] Specifically, the first mounting plate 22 and the second mounting plate 23 serve as the basic frame of the fixing mechanism 20, forming a multi-layer support structure through the connection of the fixed shelf 24 and the movable shelf 25. The movable shelf 25 and the fixed shelf 24 are respectively fixed to the mounting plates at both ends, ensuring the overall rigidity of the fixing mechanism 20. The first slot on the movable shelf 25 corresponds one-to-one with the second slot on the fixed shelf 24. When a workpiece is placed in the slot, the position of the movable shelf 25 is adjusted to create a closed mounting position between the first and second slots. A clamping member 21 is installed on the movable shelf 25. After the workpiece is inserted into the slot, operating the clamping member 21 pushes the movable shelf 25 towards the fixed shelf 24, thereby applying pre-pressure to the workpiece and ensuring its stability during baking.

[0029] Through the above technical solution, this utility model solves the problem of glue overflow caused by the simple structure of traditional fixtures. The adjustable slots and clamping mechanism ensure that the workpiece remains stable and fixed during high-temperature baking, reducing the possibility of glue flowing due to heat. At the same time, it reduces the maintenance frequency of the fixture and improves the reliability and operational efficiency of the repair process.

[0030] In some embodiments, a movable shelf 25 includes a first fixed rod 251 and a movable frame 252. The inner side of the first fixed rod 251 is provided with a movable groove. The two sides of the movable frame 252 in the first direction are respectively movably disposed in the movable grooves of the two first fixed rods 251. A first slot is disposed on the movable frame 252. A clamping member 21 is disposed on the movable frame 252 in the second direction and is subjected to force through the clamping member 21 so that the movable frame 252 slides in the movable groove.

[0031] In this embodiment, the first fixed rod 251 is a basic structural component used to support the movable frame 252, which can be made by machining a metal profile. Its inner movable groove provides a sliding guide function for the movable frame 252. The movable groove is a linear groove formed inside the first fixed rod 251, which can be made by milling or extrusion molding, and is used to limit the movement trajectory of the movable frame 252. The first slot is an opening structure provided on the movable frame 252, which can be formed by stamping or cutting, and is used to hold the workpiece to be processed. The clamping member 21 is a mechanical component that applies pressure, which can be implemented using a screw and knob structure. By adjusting the knob, the movable frame 252 is driven to slide along the movable groove to clamp the workpiece.

[0032] Specifically, the movable frame 252 is slidably connected by embedding its two sides into the movable slots of the first fixed rod 251. When the clamping member 21 is subjected to an external force, the movable frame 252 moves along the linear direction of the movable slots, creating a clamping space between the first slot and the second slot of the fixed shelf 24. By adjusting the displacement of the clamping member 21, the preload of the movable frame 252 on the workpiece can be controlled, ensuring that the workpiece maintains a stable posture during baking. The guiding function of the movable slots prevents the movable frame 252 from shifting during sliding, thereby ensuring a uniform distribution of the clamping force.

[0033] Through the above technical solution, this utility model can adapt to the clamping requirements of workpieces of different specifications and ensure the uniformity of pressure distribution during the pre-pressing process. The adjustable design of the movable frame 252 avoids the residue of adhesive caused by repeated disassembly of the clamp, and at the same time reduces the risk of workpiece surface contamination caused by structural misalignment. The synergistic effect of the clamping member 21 and the movable groove improves the clamping stability, keeps the workpiece in a fixed position during high-temperature baking, and reduces the overflow caused by the thermal flow of adhesive.

[0034] In some embodiments, the first mounting plate 22 or the second mounting plate 23 is provided with a connecting screw hole 121; the clamping member 21 includes a rod and a cap, the first end of the rod passes through the connecting screw hole 121 and is fixedly connected to the movable frame 252, and the second end of the rod is connected to the cap.

[0035] In this embodiment, the connecting screw hole 121 refers to a threaded hole structure provided on the first mounting plate 22 or the second mounting plate 23. Specifically, it can be implemented by machining an internal thread from a metal sheet, used to form a threaded engagement with the rod body to transmit pressure. The rod body refers to a rigid component with a threaded structure, specifically made of stainless steel to form a rod-shaped structure. One end of the rod body passes through the connecting screw hole 121 and is fixedly connected to the movable frame 252, used to convert rotational motion into linear displacement. The cap body refers to an operating component located at the end of the rod body, specifically a metal disc structure with anti-slip texture, fixed to the end of the rod body by welding or threaded connection, facilitating manual rotation to adjust the clamping force.

[0036] Specifically, when it is necessary to adjust the clamping state of the movable frame 252 on the workpiece, the rod can be driven to move axially along the connecting screw hole 121 by rotating the cap. When the rod moves, it causes the movable frame 252 to slide in the movable groove of the first fixed rod 251, thereby changing the distance between the movable frame 252 and the fixed shelf 24, realizing the pre-pressing or release of the workpiece. Since the rod and the connecting screw hole 121 are connected by a thread, its movement accuracy and self-locking can avoid the decrease of clamping force caused by material expansion under high temperature environment.

[0037] Compared to existing technologies, traditional clamping structures often employ fixed bolts or non-adjustable snap-fit ​​designs, which are prone to pre-compression failure due to material deformation during high-temperature baking. This solution, through a threaded rod and connecting screw hole 121, not only achieves precise adjustment of the clamping force but also maintains a stable connection under high-temperature conditions, avoiding loosening problems caused by thermal expansion.

[0038] Through the above technical solution, this utility model solves the problem of workpiece displacement caused by easy failure of the clamping structure during high-temperature baking, reduces the risk of glue overflow, simplifies the fixture adjustment operation process, and improves the stability and yield of optical component repair process.

[0039] In some embodiments, the movable frame 252 is provided with a second fixed rod and a first connecting rod. The second fixed rod is provided with a first insertion hole, and the two ends of the first connecting rod are respectively inserted into the first insertion holes of the two second fixed rods.

[0040] In this embodiment, the second fixing rod refers to a rod-shaped component used to support the transverse structure of the movable frame 252. Specifically, it can be made of metal and machined into a rod with insertion holes, forming a detachable connection with the first connecting rod through these holes. The first insertion hole refers to a through-hole structure provided on the second fixing rod, which can be machined by drilling or stamping, and is used to accommodate the end of the first connecting rod. The first connecting rod refers to a rod-shaped component that transversely connects the two second fixing rods. Specifically, it can be made of a metal rod of the same material as the second fixing rods, with both ends inserted into the first insertion hole to form a stable frame structure.

[0041] Specifically, during the assembly of the movable frame 252, the second fixing rod is fixed to both sides of the movable frame 252, and the two ends of the first connecting rod are respectively inserted into the first insertion holes of the second fixing rods on both sides. This plug-in connection enhances the overall structural rigidity of the movable frame 252 and facilitates disassembly and maintenance. During high-temperature baking, the plug-in structure effectively disperses thermal stress, preventing structural deformation caused by material thermal expansion.

[0042] Through the above technical solution, this utility model solves the problem of glue overflow caused by easy deformation of the movable frame 252 during high-temperature baking. The frame stability is improved by the plug-in structure, which reduces the possibility of glue overflow due to structural deformation. At the same time, it is easy to disassemble, clean or replace parts, thereby improving the yield and efficiency of optical component repair work.

[0043] In some embodiments, there are two fixed shelves 24, and the two fixed shelves 24 and the movable shelf 25 are arranged sequentially between the first mounting plate 22 and the second mounting plate 23, with the movable shelf 25 located between the two fixed shelves 24, so as to pre-press the middle part of the workpiece after the workpiece is fixed.

[0044] In this embodiment, the fixed shelf 24 refers to the support structure fixed between the first mounting plate 22 and the second mounting plate 23 by bolts. Specifically, it can be implemented by combining a third fixing rod 241 with a second slot and a second connecting rod 242 to form a stable workpiece mounting position. The movable shelf 25 refers to a structure that can slide along the movable groove of the first fixing rod 251. Specifically, it can be implemented by combining a first slot and a clamping member 21 to apply adjustable preload to the workpiece. The first mounting plate 22 and the second mounting plate 23 refer to the supporting bodies on both sides of the fixing mechanism 20. Specifically, they can be formed by processing metal sheets and are used to support the connection between the fixed shelf 24 and the movable shelf 25. Preload refers to the initial pressure applied by the clamping member 21 during the workpiece fixing process. Specifically, it can be implemented by rotating the cap body to drive the rod body to slide the movable shelf 252, which is used to eliminate workpiece deformation and improve fixing stability.

[0045] Specifically, two fixed shelves 24 are respectively installed at the two ends of the first mounting plate 22 and the second mounting plate 23, and a movable shelf 25 is positioned at the center between the two fixed shelves 24. When the glass workpiece is placed in the mounting position formed by the second slot of the fixed shelf 24 and the first slot of the movable shelf 25, the clamping member 21 is operated to drive the movable shelf 252 to slide towards the fixed shelf 24. At this time, the movable shelf 25, located in the middle of the workpiece, generates symmetrical pre-pressure on the workpiece. This arrangement ensures that the two ends of the workpiece are constrained by the fixed shelves 24, and the middle is subjected to uniform pressure by the movable shelf 25, which can effectively suppress the bending deformation of the workpiece caused by thermal expansion during high-temperature baking.

[0046] Through the above technical solution, this utility model can significantly reduce the micro-bending of optical glass caused by uneven stress during high-temperature baking, and prevent the protective adhesive from overflowing due to workpiece deformation. The combination of symmetrically distributed fixed shelves 24 and movable shelves 25 keeps the workpiece under uniform pressure during baking, reduces the risk of contact between the adhesive and the glass surface, and improves the structural reliability of the fixture during multiple high-temperature cycles.

[0047] In some embodiments, the bottom of the fixing mechanism 20 is also provided with a tray, with the two ends of the tray between the first mounting plate 22 and the second mounting plate 23 respectively, and the tray is located below the fixed shelf 24 and the movable shelf 25.

[0048] In this embodiment, the tray refers to a support structure located at the bottom of the fixing mechanism 20, used to collect colloids or debris that may overflow from the surface of the workpiece during high-temperature baking. It can be implemented using a metal plate or a high-temperature resistant plastic plate, with flanged edges to prevent liquid leakage. The first mounting plate 22 and the second mounting plate 23 refer to the support components on both sides of the fixing mechanism 20. The two ends of the tray are fixed between them by bolts or snap-fits, ensuring the tray remains stable when the fixing mechanism 20 moves or is heated. The fixed shelf 24 and the movable shelf 25 refer to the layered structure inside the fixing mechanism 20 for placing workpieces. The tray is located below both, directly catching colloids or detached particles dripping from the upper workpiece.

[0049] Specifically, when the workpiece is pressed and baked at high temperature on the fixed shelf 24 and the movable shelf 25, the high-temperature adhesive may become more fluid due to thermal expansion, causing some adhesive to overflow from the edges of the workpiece. At this time, the tray is positioned below the shelf, allowing the overflowing adhesive to drip directly onto the tray surface, preventing contact with the oven body 11 or other workpieces. For example, the tray can be rigidly connected to the first mounting plate 22 and the second mounting plate 23 via its fixed ends on both sides, preventing positional displacement due to heat deformation. Furthermore, the tray surface can be coated with an anti-stick coating, facilitating the direct peeling of the solidified adhesive during subsequent cleaning.

[0050] Through the above technical solution, this utility model can effectively collect the colloid overflowing during high-temperature baking, avoid the colloid adhering to the surface of optical glass and causing it to be scrapped, and at the same time reduce the problem of internal oven pollution caused by colloid residue, thereby improving the stability and maintainability of the repair process.

[0051] In some embodiments, the fixed shelf 24 includes a third fixing rod 241 and a second connecting rod 242. The third fixing rod 241 is provided with a second insertion hole 243, and the two ends of the second connecting rod 242 are respectively inserted into the second insertion holes 243 of the two third fixing rods 241.

[0052] In this embodiment, the third fixing rod 241 refers to a longitudinal rod-shaped component used to support and fix the second connecting rod 242. Specifically, it can be made of metal and machined into a rod body with a second insertion hole 243, which is used to accommodate the end of the second connecting rod 242. The second connecting rod 242 refers to a rod-shaped component that laterally connects the two third fixing rods 241. Specifically, it can be made of the same material as the third fixing rod 241 and have insertion structures at both ends, achieving assembly with the third fixing rod 241 through insertion. The second insertion hole 243 refers to a through hole or blind hole structure opened on the third fixing rod 241. Specifically, it can be formed by drilling or stamping processes, and the hole diameter matches the end diameter of the second connecting rod 242 to achieve a tight insertion.

[0053] Specifically, the third fixing rod 241 forms the main structure of the fixed shelf 24 by interlocking with the second connecting rod 242 through the second insertion hole 243. During assembly, both ends of the second connecting rod 242 are respectively inserted into the second insertion holes 243 of the two third fixing rods 241, achieving lateral connection through the insertion method. This insertion structure allows the fixed shelf 24 to remain stable in high-temperature environments, avoiding structural deformation caused by thermal expansion. At the same time, the insertion method facilitates disassembly and maintenance, allowing for quick replacement of the second connecting rod 242 or the third fixing rod 241 after the high-temperature adhesive ages, reducing assembly errors caused by operational mistakes.

[0054] Through the above technical solution, this utility model can improve the structural stability of the fixed shelf 24 in high-temperature environments, avoid installation position displacement caused by thermal deformation, and thus ensure uniform stress on the workpiece during baking. The plug-in structure simplifies the disassembly process, facilitates quick replacement of damaged parts, reduces maintenance costs and reduces the risk of operational errors, ultimately improving the repair yield and production efficiency of optical components.

[0055] In some embodiments, the two ends of the first fixing rod 251 are fixed to the first mounting plate 22 and the second mounting plate 23 by bolts; the two ends of the third fixing rod 241 are fixed to the first mounting plate 22 and the second mounting plate 23 by bolts.

[0056] In this embodiment, bolt fixing refers to the use of threaded fasteners to achieve a rigid connection. Specifically, hexagonal head bolts with nuts can be used, and tightening the bolts generates axial preload to press the rod body and mounting plate together. This method provides stable mechanical support and avoids loosening of the connection due to adhesive failure at high temperatures. The first fixing rod 251 is a longitudinal support component in the movable shelf 25 used to support the movable slot. Specifically, it can be implemented using a rectangular metal profile, with bolt holes at both ends aligned with corresponding holes on the mounting plate. This structure ensures that the movable shelf 25 maintains overall rigidity during high-temperature baking, preventing slot misalignment due to thermal deformation.

[0057] Specifically, threaded positioning holes are pre-machined on the surface of the mounting plate, and through holes are opened at the ends of the first fixing rod 251 and the third fixing rod 241. During assembly, bolts are screwed into the positioning holes through the through holes, and a set torque is applied using a torque wrench to complete the tightening. This connection method enables the movable shelf 25 and the fixed shelf 24 to form a stable frame structure, maintaining geometric accuracy even when subjected to workpiece preload and high-temperature thermal stress, and avoiding clamping failure due to shelf displacement.

[0058] Through the above technical solution, this utility model achieves reliable fixation of the shelf assembly under high-temperature conditions, solving the problem of adhesive overflow contaminating optical components. The mechanical stability of the bolted connection reduces the frequency of fixture maintenance, while the standardized assembly process reduces the probability of operational errors and ensures the repeatability and accuracy of the repair process.

[0059] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a third embodiment of the glass baking apparatus to further describe the oven and the fixing mechanism 20.

[0060] In this embodiment, a slide rail is provided on the bottom inner side of the oven body 11, and a slide seat matching the slide rail is provided on the bottom of the fixing mechanism 20. The fixing mechanism 20 is movable within the oven body 11 via the slide rail.

[0061] The slide rail refers to the guide structure extending along the length of the oven body 11. It can be made of metal and fixed to the inner wall of the oven bottom, for example, using a stainless steel track secured with bolts. Its function is to provide a linear movement path for the fixing mechanism 20 and limit offset. The slide block refers to the load-bearing component adapted to the shape of the slide rail. It can be a U-shaped groove structure with rollers, for example, two sets of rollers welded to the bottom of the fixing mechanism 20 and fitted into the slide rail. Its function is to achieve smooth movement and accurate positioning of the fixing mechanism 20 within the oven through rolling friction.

[0062] Specifically, the slide rails are symmetrically distributed along both sides of the oven bottom, and the slide block is fitted with the slide rails via rollers. When the fixing mechanism 20 needs to be installed in or removed from the oven, the operator pushes or pulls the fixing mechanism 20 along the slide rails, and the slide block rolls on the slide rails to achieve low-resistance movement. During the baking process, the rigid contact between the slide rails and the slide block prevents the fixing mechanism 20 from shifting due to thermal expansion, while the roller structure reduces frictional wear on the metal contact surfaces under high-temperature conditions.

[0063] Compared with existing technologies, traditional baking equipment often uses a flat support method without a guide structure. When the fixing mechanism 20 moves, it is prone to jamming or displacement, requiring repeated adjustments and resulting in low operating efficiency. In contrast, this solution uses the cooperation of slide rails and slide blocks to achieve rapid positioning of the fixing mechanism 20 and avoid the risk of equipment collision caused by uneven force during manual pushing and pulling.

[0064] Through the above technical solution, the present invention enables the fixing mechanism 20 to maintain a stable moving trajectory in a high-temperature environment, reduces the problem of uneven pressure on the glass caused by positional deviation, and reduces the probability of high-temperature adhesive overflowing due to external pressure during operation, thereby improving the repair yield of optical components.
