[0003] During the processing of glass gaskets, the selection should be based on requirements such as heat resistance, light transmittance, and mechanical strength. Grinding and polishing methods are used to reduce the thickness of the glass from millimeters to micrometers. The glass sheets are cut into circles, squares, or irregular shapes, and grinding debris and oil stains are removed. Finally, a coating is applied to reduce the reflection of the glass surface. They are widely used in optoelectronics, semiconductors, precision optics and other fields.
[0004] During the glass cutting process, when the glass cutter squeezes and slides the glass, the glass will slide because the glass cutter is squeezing the glass and causing the cutting line to deviate from the design size. Therefore, a glass gasket cutting device for optical device packaging is proposed to address the above problem. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a glass gasket cutting device for optical device packaging includes a transmission frame 1; a plurality of rollers 11 are rotatably connected to the middle of the transmission frame 1; a support plate 12 is fixedly connected to the bottom of the transmission frame 1; a set of electric push rods 13 are fixedly connected to the top of the support plate 12; a connecting block 14 is fixedly connected to the output end of the electric push rods 13; a flexible tube 15 is installed on one side of the connecting block 14; a diaphragm pump is installed at the end of the flexible tube 15; a suction cup 16 is fixedly connected to the top of the connecting block 14; the flexible tube 15 and the suction cup 16... For connectivity, a gantry frame 17 is slidably connected to the surface of the transmission frame 1; a set of spring telescopic rods 18 are fixedly connected to the bottom of the gantry frame 17; a connecting plate 19 is fixedly connected to the output end of the spring telescopic rods 18; a reciprocating motor 110 is installed in the middle of the connecting plate 19; a mounting block 111 is fixedly connected to the load end of the reciprocating motor 110; a glass cutter 112 is installed at the bottom of the mounting block 111; during operation, glass is placed on the rollers 11, and the glass is pushed to rotate the rollers 11, thus conveying the glass to a position above the multiple rollers 11. Then, the electric actuator 13 is raised to allow the suction cup 16 to contact the lower surface of the glass for adsorption. At this time, the diaphragm pump is turned on, which draws out the air between the suction cup 16 and the glass through the hose 15 to form a vacuum state for fixing the glass. The gantry frame 17 is moved to the designated position, and the reciprocating motor 110 is moved to the end of the connecting plate 19. Then, the spring telescopic rod 18 is controlled to extend and retract to push the connecting plate 19, so that the glass cutter 112 contacts the glass surface. The reciprocating motor 110 is controlled to move to the other end of the connecting plate 19, so that the glass cutter 112 slides across the glass surface. The above operation is repeated to cut the glass into the required size. Then, the diaphragm pump is controlled to inject air to separate the suction cup 16 from the glass. Finally, the worker breaks the glass along the scratch to complete the cutting. By drawing out the air between the suction cup 16 and the glass through the diaphragm pump for fixing, a large area of negative pressure can be formed at the bottom of the glass, so that the glass surface is subjected to uniform vertical adsorption force. This reduces the glass deformation or edge cracking caused by point contact or line contact of traditional mechanical clamps, reduces the risk of glass breakage, increases the product qualification rate, and reduces production costs.
[0025] like Figure 1 and Figure 3As shown, the transmission frame 1 has multiple internally threaded cylinders 2 rotatably connected to its middle section; each internally threaded cylinder 2 has a threaded rod 21 threadedly connected to it; a handle 22 is fixedly connected to one side of each internally threaded cylinder 2; a support 23 is fixedly connected to one side of each threaded rod 21; and a guide roller 24 is rotatably connected to the middle of the support 23. During operation, after placing the glass on the roller 11, the handle 22 is rotated to extend the threaded rod 21, pushing the guide roller 24 to contact the glass side. Continuing to rotate the handle 22 causes the glass to be squeezed into the middle position of the roller 11. By rotating the handle 22 to push the guide roller 24 to squeeze the edge of the glass and center it, the glass can move linearly along a set trajectory. When the guide roller 24 contacts the edge of the glass, it guides the glass forward through rolling friction, reducing edge wear and correcting the glass to reduce tilting during placement, thus reducing cutting size deviations and increasing cutting accuracy.
[0026] like Figure 1 and Figure 5 As shown, a set of rotating seats 3 are fixedly connected to one side of the transmission frame 1; a stepper motor 31 is fixedly connected to one side of the rotating seat 3; a transmission rod 32 is fixedly connected to the output end of the stepper motor 31; the transmission rod 32 is located in the middle of the rotating seat 3; the transmission rod 32 and the rotating seat 3 are rotatably connected; a pressure rod 33 is fixedly connected between the set of transmission rods 32; a sliding plate 34 is fixedly connected to the middle of the transmission frame 1; the sliding plate 34 is inclined; during operation, after the glass is cut to the specified size, the glass is pushed to the end of the transmission frame 1, and the stepper motor is controlled. Rotation of step 31 causes transmission rod 32 to drive pressure rod 33 to swing and squeeze the glass, causing it to break along the scratch. The cut glass slides down the inclined surface of slide plate 34 and is collected. By setting stepper motor 31 at the end of transmission frame 1, pressure rod 33 can replace manual glass breaking and directly enter the breaking process after glass cutting, reducing manual handling time and increasing cutting efficiency. At the same time, the rotation of stepper motor 31 makes the force direction of pressure rod 33 consistent with the cutting line, so that the break extends along the preset cut, increasing breaking accuracy and reducing glass breakage rate.
[0027] like Figure 1 , Figure 2 and Figure 4As shown, an air inlet pipe 4 is fixedly connected to one side of the gantry frame 17; an air pump is installed at one end of the air inlet pipe 4; multiple air outlets 41 are opened on the inner wall of the gantry frame 17; the air outlets 41 are connected to the air inlet pipe 4; a baffle 42 is fixedly connected to the inner wall of the gantry frame 17; the baffles 42 are arranged correspondingly; during operation, the air pump is turned on so that gas is blown out from the multiple air outlets 41 through the air inlet pipe 4. When passing the glass cutter 112, the dust and glass fragments generated during cutting are blown towards the baffle 42 and collected along the surface of the baffle 42. By blowing gas out from the multiple air outlets 41 during glass cutting, fine glass fragments and cutting dust near the cutting line can be blown away, reducing the amount of debris that rises the glass and causes the glass cutter 112 to not fully contact the glass surface, resulting in insufficient cutting depth or broken lines, and causing chipping or deviation of the breakage path when breaking the glass, thus increasing the quality and efficiency of breaking the glass.
[0028] like Figure 1 and Figure 4 As shown, a kerosene canister 5 is fixedly connected to one side of the mounting block 111; a ball bearing 51 is rotatably connected to the bottom of the kerosene canister 5; an oil filling nozzle 52 is provided on the surface of the kerosene canister 5; a one-way valve is provided in the middle of the oil filling nozzle 52; during operation, kerosene is injected into the oil filling nozzle 52. When the glass cutter 112 cuts the glass, the ball bearing 51 contacts the glass surface. When the glass cutter 112 moves, the ball bearing 51 rolls on the glass surface. The kerosene inside the kerosene canister 5 coats the surface of the ball bearing 51. As the ball bearing 51 rolls, it spreads along the moving trajectory. By spreading kerosene along the moving path of the glass cutter 112, the kerosene can penetrate into the contact surface between the glass cutter 112 and the glass, forming an oil film. This reduces frictional wear between the glass cutter 112 and the glass, reduces cutting resistance, and increases the service life of the glass cutter 112. At the same time, the two sides of the cutting seam will temporarily close due to elastic recovery. After the kerosene penetrates into the cutting seam, it fills the gap, keeps the opening open, and increases the flatness of the fracture surface.
[0029] like Figure 1 and Figure 5 As shown, a silicone sleeve 6 is fixedly attached to the surface of the pressure rod 33; the silicone sleeve 6 is correspondingly set to the pressure rod 33; during operation, it is fitted onto the surface of the pressure rod 33 to reduce the instantaneous pressure generated when the pressure rod 33 squeezes the glass. By installing the silicone sleeve 6 on the surface of the pressure rod 33, the silicone sleeve 6 can disperse the pressure generated when the pressure rod 33 contacts the glass through its own elastic deformation, making the fracture process more stable. At the same time, when the pressure rod 33 contacts the glass, the silicone sleeve 6 reduces direct collision, buffers the impact force, and increases fracture stability.
[0030] Working principle: Glass is placed on rollers 11, and the glass is pushed to rotate the rollers 11, transporting the glass above multiple rollers 11. Then, the electric push rod 13 is raised, causing the suction cup 16 to contact the lower surface of the glass for adsorption. At this time, the diaphragm pump is activated, sucking out the air between the suction cup 16 and the glass through the hose 15, creating a vacuum to fix the glass. The gantry 17 is moved to the designated position, and the reciprocating motor 110 is moved to the end of the connecting plate 19. Then, the spring telescopic rod 18 is extended and retracted to push the connecting plate 19, causing the glass cutter 112 to contact the glass surface. The reciprocating motor 110 is moved to the other end of the connecting plate 19, allowing the glass cutter 112 to slide across the glass surface. This process is repeated to cut the glass into the required sizes. Then, the diaphragm pump is used to inject air to separate the suction cup 16 from the glass. Finally, a worker breaks the glass along the scratches to complete the cutting. After placing the glass on rollers 11, the handle 22 is turned to extend the threaded rod 21, pushing the guide roller 24 to contact one side of the glass. The handle 22 is continued to be turned to further press the glass... The glass is squeezed into the middle of the roller 11. By rotating the handle 22, the guide roller 24 is pushed to squeeze the edge of the glass and center it, so that the glass can move in a straight line along the set trajectory. When the guide roller 24 contacts the edge of the glass, after the glass is marked with the cutting size, it is pushed to the end of the transfer frame 1. The stepper motor 31 is controlled to rotate, so that the transmission rod 32 drives the pressure rod 33 to swing and squeeze the glass, causing it to break along the scratch. The cut glass slides down the inclined surface of the slide plate 34 for collection. The air pump is turned on so that the air comes out through the air inlet pipe 4 from multiple air outlets 4. 1. When the glass cutter 112 passes through the glass cutter, it blows the dust and glass shards generated during cutting toward the baffle 42. The dust and glass shards fall and are collected along the surface of the baffle 42. Kerosene is injected into the filler nozzle 52. When the glass cutter 112 cuts the glass, the ball bearing 51 contacts the glass surface. As the glass cutter 112 moves, the ball bearing 51 rolls on the glass surface. The kerosene inside the kerosene canister 5 coats the surface of the ball bearing 51. As the ball bearing 51 rolls, it spreads along the moving path and fits on the surface of the pressure rod 33, reducing the instantaneous pressure generated when the pressure rod 33 squeezes the glass.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
