Description

Technical Field

[0001] This utility model relates to the field of optical glass forming technology, specifically to a large-diameter automatic pouring optical glass forming equipment. Background Technology

[0002] As the core optical component substrate of optical instruments, the molding quality of optical glass directly affects the imaging accuracy and performance of optical systems. With the development of optical technology towards larger field of view and higher resolution, the market demand for large-diameter optical glass components is increasing. The diameter of such components often needs to reach tens of centimeters or even larger, which places higher demands on the automation level of equipment, material handling accuracy, and production efficiency in the molding and processing process.

[0003] Optical glass molding is a key process for processing molten glass raw materials into blanks of a specific shape. The glass raw materials must first be transported into the mold, and then pressed and shaped under specific temperature and pressure conditions.

[0004] For example, Chinese utility model patent application number 202420652139.3 discloses an optical glass forming device. By setting the forming components, it avoids the problem that most forming devices lack the ability to easily replace the pressure head, which makes it inconvenient to quickly form the required glass shape, thus improving the flexibility of the optical glass forming device. However, the device still has certain shortcomings. The lack of an automatic structure for pouring optical glass blanks into the mold means that the blanks must be placed into the mold one by one by manual labor. This not only results in low efficiency but also poses a significant safety hazard, as it can easily cause burns to workers when placing the blanks.

[0005] Therefore, we propose a large-diameter automatic pouring optical glass forming equipment to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a large-diameter automatic pouring optical glass molding equipment to solve the problem mentioned in the background art that the current market lacks a structure for automatically pouring optical glass blanks into the mold, and that it is necessary to rely on manual labor to place the blanks one by one into the mold. This not only results in low efficiency of manual operation, but also easily causes workers to be burned when placing blanks, posing a significant safety hazard.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter automatic pouring optical glass forming equipment, comprising a support frame and a storage box, a worktable installed above the support frame, and vertical blocks installed on both the left and right sides of the upper surface of the worktable, a top plate installed above the vertical blocks via guide rods, a base installed between the vertical blocks, a pressing head assembly installed below the top plate, a storage box installed on the rear side of the worktable, and a conveying slide installed between the worktable and the storage box; The storage box has a push plate at its inner bottom, and a first connecting block is installed on the rear side of the push plate. A movable component is hinged to the right side of the first connecting block, and a connecting strip is hinged to the right side of the movable component. An internal groove is opened at the lower rear side of the storage box, and a horizontal plate and a second cylinder are installed inside the internal groove.

[0008] Preferably, the upper surface of the base is provided with a molding groove, the pressing head assembly is located directly above the molding groove, and the center line of the molding groove coincides with the center line of the pressing head assembly.

[0009] With the above structural design, the molding groove on the upper surface of the base is used to place the optical glass blank. The pressing head assembly is located directly above the molding groove and the center lines of the two coincide, ensuring that the pressing head assembly can accurately act on the blank in the molding groove when pressing down, avoiding shape deviation of the molded product due to misalignment, and ensuring the molding accuracy of large-diameter optical glass.

[0010] Preferably, a first cylinder is installed above the top plate, and a movable plate is installed below the first cylinder via a first telescopic rod. The movable plate passes through the guide rod and is slidably connected to the guide rod.

[0011] With the above structural design, after the first cylinder above the top plate is started, it drives the movable plate to rise and fall through the first telescopic rod. The movable plate passes through the guide rod and is slidably connected to the guide rod. The guide rod restricts the movement trajectory of the movable plate to prevent it from deviating or shaking when the movable plate drives the pressure head assembly to rise and fall, thus ensuring that the pressure head assembly presses down smoothly and improving the stability of the forming process.

[0012] Preferably, the lower surface of the storage box is provided with a discharge groove, and the width of the discharge groove is greater than the thickness of a single optical glass blank by 1 cm. The surface of the push plate is designed with a smooth structure, and the push plate is slidably connected to the storage box.

[0013] With the above structural design, the width of the discharge slot on the lower surface of the storage box is adapted to a single optical glass blank, ensuring that the blank can pass through the discharge slot one by one and avoiding congestion due to multiple materials; the surface of the push plate is smooth, reducing frictional resistance with the blank, so that the push plate can smoothly push the blank out of the discharge slot when pushing it, ensuring that the automatic discharge process is not stuck and improving the feeding efficiency.

[0014] Preferably, the conveying chute is designed with an inclined structure and is connected to the discharge chute. Conveying rollers are installed on the conveying chute, and multiple conveying rollers are provided. The end of the conveying chute is close to the base.

[0015] With the above structural design, the inclined conveying slide is connected to the discharge chute. After the billet is pushed out of the discharge chute, it can slide down the conveying slide with the help of gravity. The multiple conveying rollers on the conveying slide further reduce the sliding resistance of the billet and speed up the conveying speed of the billet. Moreover, the end of the conveying slide is close to the base, so that the billet can be conveyed into the mold groove under the action of inertia and gravity, without the need for secondary manual handling.

[0016] Preferably, a second connecting block is installed on the right side of the horizontal plate, and the second connecting block is hinged to the connecting strip.

[0017] With the above structural design, when the connecting bar is subjected to force and moves, it can drive the horizontal plate to move synchronously through the second connecting block. At the same time, the fixed structure of the horizontal plate provides stable support for the connecting bar, ensuring that the power can be effectively transmitted to the moving component and the first connecting block, and finally drive the push plate to move.

[0018] Preferably, a fixing block is installed below the horizontal plate, and a movable frame is hinged below the fixing block. The second cylinder is fixed to the rear side of the movable frame, and a third connecting block is installed on the rear side of the second cylinder through a second telescopic rod. The third connecting block is hinged to the connecting strip.

[0019] With the above structural design, the fixed block below the horizontal plate is hinged to the movable frame, and the second cylinder is fixed to the rear side of the movable frame; the second cylinder drives the third connecting block to extend and retract through the second telescopic rod, and the third connecting block is hinged to the connecting strip. This structure increases the effective stroke of the second cylinder, thereby pushing the connecting strip to drive the push plate to move back and forth, so as to realize the automatic pouring and discharge of optical glass blanks.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This large-diameter automatic pouring optical glass forming equipment: 1. Enables fully automated feeding of optical glass blanks, replacing manual operation and improving efficiency and safety. The equipment stores the blanks in the storage bin. The second cylinder in the built-in slot drives the connecting bar, which in turn drives the push plate to move back and forth through the movable component and the first connecting block, pushing the blanks out of the discharge slot. The inclined conveyor slide, together with multiple conveyor rollers, automatically conveys the blanks to the pressing mold slot of the base. The entire process does not require manual contact with the high-temperature blanks, completely solving the problems of low efficiency and easy burns caused by manual feeding. At the same time, it ensures continuous feeding and improves the production efficiency of large-diameter optical glass pressing. 2. Balancing molding precision with equipment protection ensures long-term stable operation. On the one hand, the pressure head assembly coincides with the center line of the mold groove. The first cylinder drives the movable plate to rise and fall smoothly along the guide rod, ensuring that the pressure head assembly presses down accurately, avoiding the offset of the large-diameter optical glass molding and ensuring molding accuracy. On the other hand, the second cylinder is fixed in the built-in groove by the movable frame, which can reduce the damage to the second cylinder caused by external collisions. At the same time, the structural design of the second cylinder increases its effective stroke, ensuring stable and fast pushing power, preventing material jamming, extending the service life of the core components of the equipment, and ensuring long-term reliable operation.

The molding groove 6 on the upper surface of the base 5 is used to place optical glass blanks. The pressing head assembly 8 is located directly above the molding groove 6, and their center lines coincide, ensuring that the pressing head assembly 8 can accurately act on the blank within the molding groove 6 when pressing down, avoiding shape deviations in the molded product due to misalignment, and ensuring the molding accuracy of large-diameter optical glass.

The discharge groove 13 is opened on the lower front surface of the storage box 12. The width of the feed trough 13 is adapted to a single optical glass blank, ensuring that the blank can pass through the discharge trough 13 individually and avoid congestion due to multiple materials. The surface of the push plate 16 is smooth, reducing frictional resistance with the blank, so that the push plate 16 can smoothly push the blank out of the discharge trough 13, ensuring that the automatic discharge process is not stuck and improving the feeding efficiency.

A movable component 18 is hinged to the right side of the first connecting block 17, and a connecting strip 19 is hinged to the right side of the movable component 18. An internal groove 20 is provided at the lower rear side of the storage bin 12, and a horizontal plate 21 and a second cylinder 25 are provided inside the internal groove 20. A second connecting block 22 is installed on the right side of the horizontal plate 21, and the second connecting block 22 is hinged to the connecting strip 19. When the connecting strip 19 is subjected to force and moves, it can drive the horizontal plate 21 to move synchronously through the second connecting block 22. At the same time, the fixed structure of the horizontal plate 21 provides stable support for the connecting strip 19, ensuring that the power can be effectively transmitted to the movable component 18 and the first connecting block 17. The push plate 16 is driven to move. A fixed block 23 is installed below the horizontal plate 21, and a movable frame 24 is hinged below the fixed block 23.

[0026] It should be noted that the base 5 of this application can be equipped with a demolding mechanism according to the actual situation. The demolding mechanism has been disclosed in the optical glass molding device with prior art application number 202420652139.3, and will not be described in detail here. At the same time, the device needs to be operated at high temperature during pressing. The heating mechanism is a technical feature that is already in the art, and will not be described in detail here. Of course, if necessary, the handling of materials can be assisted by anti-scalding tools.

[0027] Working principle: When using this large-diameter automatic feeding optical glass forming equipment, firstly, in the automatic feeding stage, the storage box 12 stores the optical glass blank. The second cylinder 25 in the built-in groove 20 is activated. The second cylinder 25 drives the third connecting block 27 to extend and retract through the second telescopic rod 26, thereby pushing the connecting strip 19 to move. The left side of the connecting strip 19 is hinged to the first connecting block 17 behind the push plate 16 through the movable component 18. At the same time, the connecting strip 19 is hinged to the second connecting block 22 on the right side of the horizontal plate 21. The horizontal plate 21 provides stable support for the connecting strip 19. Finally, the push plate 16 is driven to slide along the bottom of the storage box 12, pushing the blank out of the discharge groove 13 on the lower surface of the storage box 12. After being pushed out, the second cylinder 25 drives the push plate 16 to move backward, causing the blank in the storage box 12 to move downward, preparing for the next feeding.

[0028] After the billet is pushed out, it enters the inclined conveying slide 14 connected to the discharge trough 13 and slides down the slide with the help of gravity. Multiple conveying rollers 15 on the conveying slide 14 further reduce the sliding resistance and speed up the conveying speed, so that the billet is accurately conveyed to the pressing groove 6 of the base 5 under the action of inertia and gravity.

[0029] During the molding stage, the first cylinder 9 above the top plate 7 is activated. The first cylinder 9 drives the movable plate 11 to slide along the guide rod 4 via the first telescopic rod 10. The guide rod 4 restricts the movement trajectory of the movable plate 11 to prevent deviation. The movable plate 11 drives the pressure head assembly 8 below to press down smoothly and precisely onto the blank in the molding groove 6, completing the molding of large-diameter optical glass. After molding, the first cylinder 9 drives the pressure head assembly 8 to reset, and the second cylinder 25 drives the push plate 16 again to enter the next round of automatic feeding and molding cycle, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
