Description

An automatic cutting method and apparatus for optical glass plates Technical Field

[0001] This invention belongs to the field of optical glass cutting technology. Specifically, it relates to a method and apparatus for online automatic cutting of optical glass block sheets, used for cutting optical glass sheets into blocks after forming and annealing. Background Technology

[0002] After the optical glass is formed and annealed, it needs to be separated into block sheets for supply.

[0003] Currently, in this industry, the process involves manually marking lines, then, based on the annealing process and operational experience, dipping the marked area in water to cool it before striking it with a rubber mallet to break it.

[0004] The problems are as follows: First, the glass produced from the furnace varies in thickness, and sometimes it is not easy to break it by simply tapping it; Second, the cutting position of block-shaped sheets is determined manually by comparing the dimensions with a reference template, which is largely due to human factors, and the cutting dimensions of each operator cannot be kept the same due to individual reasons; Third, each person has different strength and operating skills, so the appearance quality of the cut surface cannot be consistent, and chipping and sloping phenomena often occur; Fourth, one person is required to be responsible for each cutting station, resulting in high labor costs. Summary of the Invention

[0005] To overcome the aforementioned technical problems, this invention provides an automatic cutting method and apparatus for optical glass sheets. Through real-time monitoring by multiple encoders installed in the cutting zone at the discharge port, the timing of the cutting is determined based on the changes in glass movement speed and displacement fed back by the encoders. The synchronization mechanism in the cutting device is controlled to move at the same speed as the glass. The marking mechanism, cooling mechanism, and pressure-breaking mechanism are positioned on the synchronization mechanism to ensure that the marking is perpendicular to the direction of movement, that the pressure-breaking pressure does not affect the normal product output speed, and to address the positioning function at the moment of product cutting. A constant-flow peristaltic pump ensures that the cooling water delivered to the marking point is intermittently continuous and uniform, effectively controlling the cooling effect of the cut surface.

[0006] The technical solution of the present invention for the cutting method is: an automatic cutting method for optical glass, used for cutting and separating block-shaped optical glass sheets after forming and annealing, characterized by including the following steps:

[0007] S00. A movement monitoring mechanism is set at the output conveyor port of the annealing furnace, and a synchronization mechanism is set along the product movement direction. A marking mechanism, a cooling mechanism and a pressing mechanism are set sequentially on the platform track of the synchronization mechanism. The marking mechanism can move left and right in a straight line along the normal direction of the discharge direction.

[0008] S01. When the glass products on the output conveyor line of the annealing furnace pass through the motion monitoring mechanism, the motion monitoring mechanism simultaneously monitors the moving speed and displacement changes of the glass products.

[0009] S02. When the mobile monitoring mechanism detects that the glass product has traveled to the marking position, the synchronization mechanism (6) starts to move. The marking mechanism moves at the same speed as the glass product under its drive. The marking mechanism descends to the product surface to mark the line and completes the marking.

[0010] S03: Subsequently, the synchronously moving cooling mechanism begins to cool the scribing lines;

[0011] S04: Subsequently, the synchronously moving breaking mechanism applies force to the product, separating the glass under pressure;

[0012] S05: Subsequently, the synchronizing mechanism stops moving synchronously and returns to its initial position, completing one cycle.

[0013] In the technical solution of the breaking method of the present invention, step S04 can preferably be: the breaking mechanism applies force to the product in two steps. The first step applies pre-pressure to the glass surface to fix the product being broken, improving the operational stability at the moment of breaking. The second step gradually increases the force to generate a reinforcing force, which separates the glass under the action of the reinforcing pressure. The pre-pressure can fix the slight sway caused by the glass being extended out of the annealing furnace, which is equivalent to a clamping force; while the reinforcing force can generate explosive force in an instant, quickly separating the glass, avoiding edge chipping of the lower break, and improving the verticality of the lower break and the breaking speed.

[0014] In the technical solution of the cutting method of the present invention, step S00 is preferably: a pushing mechanism is provided on the track of the synchronous mechanism platform, located below the cutting mechanism. When a photoelectric switch located in the cutting zone senses information that a cutting product is on the worktable, the pushing mechanism begins to move, conveying the separated optical glass block to the next working area, leaving space for the next glass product to be cut.

[0015] In the technical solution of the cutting method of the present invention, step S03 can preferably be as follows: after the scribing operation is completed, the synchronization mechanism temporarily stops moving. When the glass moves to the cooling position under the action of the conveying force of the annealing furnace, the synchronization mechanism moves again until the cutting mechanism completes its action, and the cooling mechanism begins to cool the scribing area. The advantages are: first, it allows for better arrangement of the positions of the scribing and cooling mechanisms, facilitating their sequential placement on the conveyor line; second, it shortens the length of the entire cutting workbench, saving material costs; third, it controls the time interval between scribing and cooling, maximizing the timely release of glass stress at the scribing area, thus improving the cutting quality and efficiency of the cross-section.

[0016] In the technical solution of the breaking method of the present invention, step S04 can preferably be: a breaking blade support plate is provided on the track of the synchronous mechanism platform at the fracture surface of the glass product, so that the glass is subjected to stable and uniform force during breaking, thereby improving the breaking quality and efficiency of the broken surface.

[0017] In step S00 of the technical solution of the cutting method of the present invention: an auxiliary pressure mechanism is set on the track of the synchronization mechanism platform, and the auxiliary pressure mechanism is located before the marking mechanism; in step S04, before the pressure breaking mechanism applies force, an auxiliary pressure is applied to the optical glass plate on the other side of the marking point at the pressure breaking point, so as to keep both sides of the glass lower section fixed and under force, which is beneficial to improve the product cutting efficiency.

[0018] In step S00 of the technical solution of the cutting method of the present invention: the scribing mechanism and the cooling mechanism are arranged sequentially along the vertical plane of the product conveying direction.

[0019] In step S00 of the technical solution of the cutting method of the present invention: the scribing mechanism and the cooling mechanism are arranged side by side along the vertical plane of the product conveying direction.

The pressure-breaking cylinder connecting plate includes an upper connecting plate and a lower connecting plate. The first spring is mounted between the upper and lower connecting plates via a spring mounting shaft. Because of the spring in the middle, this pressure-breaking cylinder connecting plate can adapt to lower-breaking glass of different thicknesses within a certain range by utilizing the spring's contractile properties. A pressure-breaking support plate is provided on the mounting bracket. The pressure-breaking cylinder passes through the pressure-breaking support plate and is connected to the upper connecting plate via a coupling. The rubber-coated pressure-breaking wheel is connected to the lower connecting plate via a rubber-coated wheel rib. The spring in the connecting plate provides a preset force to the glass, facilitating glass fixation during pressure breaking. A proportional adjustment valve controls the cylinder, providing linear reinforcement force. This dual force application improves the quality, efficiency, and stability of the lower-breaking process.

[0023] The pressure breaking mechanism described in the technical solution of the lower breaking device of the present invention also includes a pressure breaking cylinder guide rod.

The horizontally and vertically movable transmission group is fixed to the synchronously moving guide plate via a marking bracket, and the marking rod is fixed to the horizontally and vertically movable transmission group. A marking blade is installed at the bottom of the marking rod. The horizontally and vertically movable transmission group can drive the marking rod blade to move horizontally and vertically on the glass conveyor line.

[0027] The transmission group that can move horizontally and vertically in the technical solution of the lower cutting device of the present invention is an electric gear and rack transmission group and an electric lead screw and nut transmission group. The electric gear and rack transmission group and the electric lead screw and nut transmission group are located on both sides of the fixed support plate and are installed on the marking bracket through the fixed support plate.

[0028] The scribing mechanism described in the technical solution of the lower cutting device of this invention also includes a blade movable rod and a third spring. To enable the scribing blade to adapt to glass products of different thicknesses without jamming or incomplete scribing, the third spring is fitted around the blade movable rod. The upper end of the blade movable rod is fitted into the scribing rod shaft cavity, and the lower end is fitted with the blade via a bearing. Thus, the blade can move 360 ​​degrees. The cylinder stroke was initially designed to accommodate a minimum glass thickness minus 1.5mm to 2.5mm. When the cylinder reaches its stroke limit, it drives the blade movable rod, causing the blade to move upwards within the scribing rod shaft cavity. The tension and constraint of the spring provide the blade with appropriate scribing force, facilitating smooth and powerful scribing.

[0031] The cooling mechanism described in the technical solution of the lower section device of this invention further includes a guide sleeve, a connecting strip, and a water inlet. A moving cylinder for the wetted felt is mounted on the pressure-breaking mechanism via a support plate. The moving cylinder is connected to the wetted felt rod via the guide sleeve. The connecting strip is positioned between the wetted felt rod and the wetted felt. The water inlet passes through the connecting strip. The guide sleeve and the wetted felt rod have a clearance fit, allowing the wetted felt rod to move freely within the guide sleeve, adapting to the cooling of glass of different thicknesses. The water pump is a constant-flow peristaltic pump, ensuring an intermittent, uniform, small volume of water is provided to the cooling area at the marked point, effectively controlling the cooling effect of the lower section.

[0057] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0058] As shown in Figures 1 to 3, one embodiment of a dedicated automatic optical glass sheet cutting device used in the cutting method of this invention includes a moving monitoring mechanism 5, a synchronization mechanism 6, a marking mechanism 2, a cooling mechanism 8, a water supply mechanism 4, an auxiliary pressure mechanism 3, a cutting mechanism 1, a pushing mechanism 7, and a fixed base frame 111. The moving monitoring mechanism 5, the auxiliary pressure mechanism 3, the marking mechanism 2, the cooling mechanism 8, and the cutting mechanism 1 are sequentially adjacent to each other along the conveying direction from the end of the annealing furnace output conveyor line. The pushing mechanism 7 is directly below the cutting mechanism 1, and the water supply mechanism 4 is fixed on the frame of the moving monitoring mechanism 5.

[0059] The mobile monitoring mechanism 5 is located at the output conveyor interface of the annealing furnace and includes a first encoder 55, a second encoder, an encoder coaxial rubber-coated wheel 56, a support frame 51, an encoder moving cylinder 52, an upper connecting plate 53, a lower connecting plate 58, second springs 54, and a monitoring track. The encoder moving cylinder 52 is mounted on a fixed frame 113 via the support frame 51, positioned directly above the moving glass product. The fixed frame 113 is connected to a fixed base frame 111. Four second springs 54 are evenly mounted between the upper connecting plate 53 and the lower connecting plate 58 via spring mounting shafts. These springs provide pre-set elasticity for the rolling soft contact with the glass, preventing slippage and avoiding incomplete contact caused by fluctuations in product thickness, ensuring normal operation and accurate detection of the encoder. The upper connecting plate 53 is connected to the encoder moving cylinder 52, and the lower connecting plate 58 is connected to the encoder coaxial rubber-coated wheel 56 via a mounting plate. The monitoring track is a second rubber-coated conveyor wheel 57, mounted on a fixed frame 113 via a support strip. The upper surface of the rubber-coated conveyor wheel 57 is horizontal with the worktable surface of the annealing furnace output conveyor line. The encoder coaxial rubber-coated wheel 56 can move up and down. The first encoder 55 and the second encoder are respectively mounted on the two shaft ends of the encoder coaxial rubber-coated wheel 56 via couplings, ensuring coaxial rotation among the three. The first encoder 55 measures the glass exit speed from the furnace, and the second encoder measures the glass displacement distance, providing accurate reference speed and displacement for the subsequent synchronization mechanism 6, and accurately determining the timing of the stop based on displacement changes. The encoder coaxial rubber-coated wheel 56 rolls in contact with the glass, detecting the glass movement in real time. The encoder coaxial rubber-coated wheel 56 uses a rubber coating process to change direct contact with the glass into soft contact, avoiding hard damage to the glass.

[0060] The breaking mechanism 1 is mounted on the synchronous moving guide plate 61 of the synchronous mechanism 6. The breaking mechanism 1 includes a rubber-coated breaking wheel 17, a breaking cylinder 11, an upper connecting plate 13 for the breaking cylinder, a lower connecting plate 15 for the breaking cylinder, a rubber-coated wheel rib plate 16, a breaking cylinder guide rod 12, first springs 14, a breaking support plate 19, and a mounting bracket 18. Four first springs 14 are evenly mounted between the upper connecting plate 13 and the lower connecting plate 15 of the breaking cylinder via spring mounting shafts. The lowering position of the rubber-coated breaking wheel 17 is fixed, but due to the elastic contraction performance of the first springs 14, the rubber-coated breaking wheel 17 is driven to move vertically, adapting to glass of different thicknesses within a certain range. At the same time, because of the springs, a pre-pressure is applied to the glass, which is equivalent to a pre-clamping force, facilitating the stability of the glass at the moment of breaking. The lower end of the breaking cylinder 11 passes through the breaking support plate 19 and is connected to the upper connecting plate 13 of the breaking cylinder via a coupling. The lower connecting plate 15 of the breaking cylinder is connected to the rubber-coated breaking wheel 17 via the rubber-coated wheel rib plate 16. The lower end of the breaking cylinder guide rod 12 passes through the lower connecting plate 15 of the breaking cylinder and is fixed thereto. The upper end of the breaking cylinder guide rod 12 passes through the breaking support plate 19 and is movably connected thereto. The breaking cylinder guide rod 12 and the breaking support plate 19 are clearance-fitted and are used to guide the up and down movement of the breaking cylinder 11. The breaking cylinder 11 is mounted on the synchronous moving guide plate 61 of the synchronous mechanism 6 via the mounting bracket 18. The circumference of the rubber-coated breaking wheel 17 is made using a rubber-coating process, resulting in soft contact with the glass and avoiding hard damage to the glass.

[0061] The synchronization mechanism 6 is mounted on the fixed base 111. The synchronization mechanism 6 includes a synchronous moving guide plate 61, a reducer 62 with a servo motor, a coupling 63, a synchronous moving nut 64, a lead screw 65, a synchronous stiffener 68, a linear guide rod 66, a ball bearing sleeve 67, a linear guide rod fixing plate 69, and a motor connecting plate. The two ends of the linear guide rod 66 are fixed to the fixed base 111 via the linear guide rod fixing plate 69 and the motor connecting plate, respectively. The reducer 62 with the servo motor is connected to the lead screw 65 via the coupling 63. The synchronous stiffener 68 is fitted onto the linear guide rod 66 via the ball bearing sleeve 67 and mounted onto the lead screw 65 via the synchronous moving nut 64. The synchronous moving guide plate 61 is fixed to the synchronous stiffener 68. The reducer 62 with the servo motor is fixed to the motor connecting plate. The reducer 62 with the servo motor drives the lead screw 65 to rotate, causing the synchronous moving nut 64 to perform linear motion. The auxiliary pressing mechanism 3 and the pressing breaking mechanism 1 are installed on the synchronous moving guide plate 61, thus moving linearly in sync with the synchronous mechanism 6. The four linear guide rods 66 guide the synchronous mechanism 6, ensuring its smooth operation. The ball bearing sleeve 67 is connected to the synchronous stiffener 68, enhancing the stability of the linear reciprocating motion of the synchronous mechanism 6.

[0062] The scribing mechanism 2 is mounted on the auxiliary pressure mechanism 3 and moves linearly synchronously with the auxiliary pressure mechanism 3 and the synchronization mechanism 6. The scribing mechanism 2 includes a blade 26, an electric gear and rack transmission assembly 21, an electric lead screw and nut transmission assembly 23, a fixed support plate 22, a scribing rod 27, a blade movable rod 24, and a third spring 25. The third spring 25 is fitted onto the outer periphery of the blade movable rod 24, which is nested within the shaft cavity of the scribing rod 27. The lower end of the blade 26 is mounted on a bearing. The scribing rod 27 is mounted on the electric gear and rack transmission assembly 21. The electric gear and rack transmission assembly 21 and the electric lead screw and nut transmission assembly 23 are respectively fixed on both sides of the fixed support plate 22 and mounted above the auxiliary pressure mechanism 3 via the fixed support plate 22. The electric gear and rack transmission assembly 21 controls the gears to drive the rack to move up and down, while the electric gear and rack transmission assembly 21 moves horizontally linearly above the product along the normal direction of the product's movement via the electric lead screw and nut transmission assembly 23. The blade 26 completes its vertical and horizontal linear movements via an electric rack and pinion transmission assembly 21 and an electric lead screw and nut transmission assembly 23. The blade's movable rod 24, in conjunction with the third spring 25, generates a certain elastic pressure on the glass product, ensuring appropriate scribing force and preventing incomplete contact caused by variations in glass thickness. Mounting the blade 26 via bearings facilitates a smoother, more even scribing process.

[0063] The cooling mechanism 8 is fixed to the side of the frame of the breaking mechanism 1, located after the marking mechanism 2, and moves linearly synchronously with the breaking mechanism 1 and the synchronizing mechanism 6. The cooling mechanism 8 includes a wetted felt 85, a wetted felt moving cylinder 81, a wetted felt rod 83, a guide sleeve 82, a connecting strip 84, a water inlet 86, and a water supply mechanism 4. The wetted felt moving cylinder 81 is mounted on the lower connecting plate 15 of the breaking cylinder via a support plate. The connecting strip 84 is located between the wetted felt rod 83 and the wetted felt 85. The water inlet 86 passes through the connecting strip 84 and is connected to a water pump via a water pipe. The wetted felt 85 is a wetted felt that is detachably connected to the connecting strip 84. The connecting strip 84 is provided with multiple water inlets 86 to provide water to the wetted felt 85. The upper end of the connecting strip 84 is fixed to one end of the wetted felt rod 83 by threads. The other end of the wetted felt rod 83 passes through the guide sleeve 82. The wetted felt rod 83 and the guide sleeve 82 are in clearance fit, allowing it to move freely up and down in a straight line. The side of the guide sleeve 82 is connected to the wetted felt moving cylinder 81.

[0064] When the marking mechanism 2 finishes marking and exits directly above the product, the wet felt can be moved towards the marked area via the wet felt moving cylinder 81, saving overall operating space for the next process. This also shortens the interval between marking and cooling, maximizing the timely release of glass stress at the marked area and improving the quality and efficiency of the cut. The water supply mechanism 4 is mounted on the frame of the moving monitoring mechanism 5. The water supply mechanism 4 includes a water tank, a water pump, and water pipes, used to supply water to the wetted felt 85. The water pump is a constant-flow peristaltic pump, providing an intermittent, uniform water supply to the wetted felt 85 in the cooling mechanism 8, achieving uniform and controllable cooling. The descent point of the rubber-coated breaking roller 17 on the breaking mechanism 1 is higher than the descent point of the wetted felt 85 fixed to the breaking mechanism 1 and the cooling mechanism 8. Although the wetted felt 85 will first contact the glass product 10 and begin to cool when the pressing mechanism 1 and the cooling mechanism 8 move down simultaneously, after the rubber-coated pressing roller 17 is in place, the wetted felt 85 will move upward on the guide sleeve 82 along with the wetted felt rod 83, and make full contact with the glass by the weight of the wetted felt 85 and the wetted felt rod 83, so as to ensure that the glass has been fully cooled when it is pressed down.

[0065] The pushing mechanism 7 is mounted under the synchronous moving guide plate 61 of the synchronizing mechanism 6. The pushing mechanism 7 includes a pushing hook 72, a pushing cylinder 71, and a pushing roller 73. The pushing cylinder 71 is mounted on the lower surface of the synchronous moving guide plate 61. The pushing hook 72 is connected to the pushing cylinder 71 via a connecting plate. The pushing cylinder 71 drives the pushing hook 72 to move the broken product along the discharge direction. The pushing mechanism 7 transports the broken product to the next working area, leaving space for the next glass product to be broken. The pressing mechanism 1, corresponding to the receiving point of the synchronous moving guide plate 61, is at a lower level than other worktable surfaces. It is used to receive broken glass products and also provides sufficient height for the pushing hook 72 to push them. Two straight [rails] are symmetrically arranged on the synchronous moving guide plate 61 along the product conveying direction. The push roller 73 includes two rollers on both sides and the roller shaft connecting them. The rollers can rotate relative to the roller shaft. The two rollers are located in the [rails] on both sides respectively. The push hook 72 is connected to each roller shaft and the push cylinder 71 through the push hook rod. The push hook 72 drives the push roller 73 to move in the [rails].

[0066] The upper planes of the second coating conveyor roller 57, the first coating conveyor roller 36, and the lower cutter edge support plate 112 are level with the worktable surface of the annealing furnace output conveyor line. The upper plane of the push hook 72 is lower than the above planes but higher than the surface of the synchronous moving guide plate 61, so as not to obstruct the glass transmission while pushing the glass products that have been cut.

[0067] A photoelectric switch 9 is installed on the synchronous moving guide plate 61 corresponding to the lower cutting mechanism 1 section. When the photoelectric switch 9 senses a product to be cut, it inputs feedback information, and the pushing mechanism 7 transports the separated optical glass block to the next working area, leaving space for the next glass product to be cut.

[0068] The auxiliary pressure mechanism 3 is located before the marking mechanism 2. The auxiliary pressure mechanism 3 includes an auxiliary pressure coated wheel 34, an auxiliary pressure wheel cylinder 31, a connecting plate 33, an auxiliary pressure mechanism support frame 35, an auxiliary pressure guide rod 32, an auxiliary pressure support plate, and an auxiliary pressure track. The auxiliary pressure wheel cylinder 31 is fixed to the synchronous moving guide plate 61 of the synchronous mechanism 6 via the auxiliary pressure mechanism support frame 35. The auxiliary pressure wheel cylinder 31 passes through the auxiliary pressure support plate on the auxiliary pressure mechanism support frame 35 and is fixed to the connecting plate 33 via a coupling. The connecting plate 33 is connected to the auxiliary pressure coated wheel 34 via stiffeners. The lower end of the auxiliary pressure guide rod 32 is fixed to the connecting plate 33, and its upper end passes through the auxiliary pressure support plate. The auxiliary pressure track is the first coated conveyor wheel 36, which is mounted on the synchronous moving guide plate 61 of the synchronous mechanism 6 via brackets. Activating the auxiliary pressure mechanism 3, based on the product thickness and temperature at the bottom cut, maintains the same pressure at both ends of the bottom cut, improving cutting efficiency and quality. The auxiliary pressure roller cylinder 31 moves up and down, causing the auxiliary pressure rubber-coated roller 34 to move downward. The auxiliary pressure guide rod 32 guides the up and down movement of the auxiliary pressure rubber-coated roller 34, enhancing the stability of the up and down movement.

[0069] A lower break support plate 112 is installed directly below the wetted felt working area. The lower break support plate 112 is fixed to the synchronous moving guide plate 61 to ensure stable and uniform force on the glass during the lower break, thereby improving the quality and efficiency of the lower break. Its position is assumed to be directly below the fracture surface of the glass product.

[0070] An embodiment of an automatic cutting method for optical glass sheets, used for cutting and separating block-shaped optical glass sheets after forming and annealing, includes the following steps:

[0071] S00. A movement monitoring mechanism 5 is set at the output conveyor port of the annealing furnace, and a synchronization mechanism 6 is set along the product movement direction. An auxiliary pressing mechanism 3, a marking mechanism 2, a cooling mechanism 8, a pressing and breaking mechanism 1 and a pushing mechanism 7 are set sequentially on the platform track of the synchronization mechanism. The marking mechanism 2 can move left and right in a straight line along the normal direction of the discharge direction. The movement monitoring mechanism 5 is fixed on the fixed base frame 111 by a fixed frame 113. The synchronization mechanism 6 is mounted on the fixed base frame 111.

[0072] S01. When the glass products on the output conveyor line of the annealing furnace pass the motion monitoring mechanism 5, the motion monitoring mechanism 5 monitors the moving speed and displacement of the glass products.

[0073] S02. When the motion monitoring mechanism 5 detects that the glass product has traveled to the designated cooling position, the synchronization mechanism 6 starts to move. Under its drive, the scribing mechanism 2 moves at the same speed as the glass product. The blade 26 of the scribing mechanism 2 descends to scribing the product surface to complete the scribing.

[0074] S03. After the marking operation is completed, the synchronization mechanism 6 temporarily stops moving. When the glass moves to the cooling position under the action of the conveying force of the annealing furnace, the synchronization mechanism moves again, and the wetted felt 85 of the cooling mechanism 8 descends to the marking position of the product and cools the marking position.

[0075] S04. Subsequently, the synchronously moving breaking mechanism 1 applies force to the product in two steps. The first step applies pre-pressure to the glass surface to fix the product to be broken, thereby improving the operational stability at the moment of breaking. The second step gradually generates a linear reinforcing force under the action of the proportional regulating valve. Under the action of the reinforcing pressure, the glass is separated. The reinforcing force can increase the burst force per unit time, which is beneficial to the verticality of the lower section and reduces edge chipping.

[0076] A bottom-breaking blade support plate 112 is provided under the fracture surface of the glass product to ensure that the glass is subjected to stable and uniform force during bottom breaking, thereby improving the bottom breaking quality and efficiency of the fracture surface.

[0077] S05. Subsequently, the pushing mechanism 7 transports the separated optical glass block to the next working area, leaving space for the next glass product to be cut off. At the same time, the synchronization mechanism 6 stops moving synchronously and returns to the initial position, completing one process.

[0078] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
