Description

Technical Field

[0001] This utility model belongs to the technical field of glass technician equipment and relates to a novel dual-head glass laser drilling machine. Background Technology

[0002] In the deep processing of glass products, it is often necessary to drill through holes or blind holes of various sizes into glass plates to meet the functional requirements of fields such as household appliance glass, decorative glass, and industrial glass. Traditional mechanical drilling methods, due to their significant damage to the glass material and poor edge quality, have been gradually replaced by laser drilling technology. A glass laser drilling machine is a device that uses a high-energy laser beam to perform non-contact drilling on glass materials. It has advantages such as high efficiency, low heat-affected zone, high precision, and wide applicability, and is widely used in multiple industries such as touch panels, display glass, and photovoltaic glass.

[0003] However, existing glass laser drilling equipment still has many shortcomings. First, most equipment uses a single laser head structure, requiring sequential drilling of each hole when dealing with multi-hole processing tasks, resulting in low processing efficiency and difficulty in meeting the demands of large-volume, high-efficiency production. Second, the automatic positioning accuracy of glass is poor, often relying on manual assistance or simple limiting structures, which can easily cause drilling position deviations and affect product yield. Furthermore, the overall automation level of the machines is generally low, still requiring manual handling, positioning, or intervention during the processing, hindering the intelligent and continuous development of the production process. Utility Model Content

[0004] The purpose of this invention is to provide a novel dual-head glass laser drilling machine to solve the problems of low drilling efficiency, inaccurate glass positioning, and low automation in existing glass drilling equipment mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A novel dual-head glass laser drilling machine includes:

[0007] Bed frame;

[0008] The feeding mechanism, located on one side above the bed, is used to transport the glass to be drilled to the processing area;

[0009] The discharge mechanism, located on the other side above the bed, is used to transport the perforated glass outwards.

[0010] A glass positioning mechanism is located above the bed, at the position of the feeding mechanism. The glass positioning mechanism includes a pusher cylinder and a flow bar on both sides of the glass conveying direction. The telescopic ends of the pusher cylinders and the flow bar are higher than the conveying plane of the feeding mechanism, so that the side of the glass can contact the telescopic ends of the pusher cylinders and the flow bar respectively. It also includes a blocking cylinder at the end of the feeding mechanism. Its telescopic end can move up and down. When it is raised, it is higher than the glass conveying surface and is used to block the glass when it is conveyed to the predetermined position.

[0011] In this process, the glass is placed on the surface of the feeding mechanism and conveyed forward. When the glass reaches the positioning position, the blocking cylinder rises to stop the glass from moving forward. Then, the pushing cylinder pushes the glass laterally so that one side of it fits the flow strip, thereby completing the precise positioning of the glass.

[0012] Preferably, both the feeding mechanism and the discharging mechanism include a mounting frame fixed above the bed, a connecting frame is installed above the mounting frame, and a conveyor is installed on the connecting frame.

[0013] Preferably, the mounting bracket is a long strip of aluminum alloy profile, and the connecting bracket is connected to the mounting bracket by bolts.

[0014] Preferably, a gap is formed between the feeding mechanism and the discharging mechanism, and a receiving trough is installed on the bed at the location of the gap.

[0015] Preferably, the receiving trough is a shell-like structure with openings on the top and one of its sides.

[0016] Preferably, the flow strip is installed at the outer edge of the feeding mechanism, and its length direction is parallel to the conveying direction of the conveyor; the pusher cylinder is located at the outer edge of the other side of the feeding mechanism, and there are at least two pusher cylinders, which are spaced apart.

[0017] Preferably, the blocking cylinder is installed on the side wall at the end of the conveyor of the feeding mechanism.

[0018] Preferably, a support cylinder that works in the vertical direction is installed at the gap between the feeding mechanism and the discharging mechanism and on the bed near the feeding mechanism, and a rotatable support wheel is installed at the end of the telescopic rod of the support cylinder.

[0019] Preferably, a crossbeam is fixed in the middle of the bed, between the feeding mechanism and the discharging mechanism. The length direction of the crossbeam is perpendicular to the glass conveying direction. At least two horizontal moving frames that move along the length direction of the crossbeam are installed on the crossbeam. A vertical lifting frame that can move vertically along the horizontal moving frame is provided on the horizontal moving frame. A laser drilling device is installed on the vertical lifting frame.

[0020] Preferably, the bed is equipped with a movable cantilever operating table.

[0021] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0022] This utility model features a rationally designed structure, employing a dual-laser drilling head structure. The two laser drilling heads can be controlled separately via a program to achieve rapid drilling, significantly improving processing efficiency. Furthermore, it integrates with a positioning mechanism composed of a pusher cylinder, a flow bar, and a blocking cylinder to achieve automatic limiting and precise alignment of the glass, ensuring accurate drilling positions. Equipped with feeding and discharging mechanisms, it constructs an automated processing flow from conveying and positioning to drilling, reducing manual intervention and improving overall automation and processing stability.

[0023] Because the glass conveyor belt uses a herringbone pattern synchronous belt, it utilizes the symmetrical interaction of the herringbone frictional tension between the belt and the glass, ensuring that the glass maintains its precise position during the conveying process after positioning. Since both laser heads move only in one direction and are located between the input and output synchronous belts, the problem of burning the belt during laser processing is avoided.

[0035] 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 protection scope of the present utility model.

[0036] As shown in the figure, a novel dual-head glass laser drilling machine includes:

[0037] Bed 1, in this example, bed 1 is made of square tubing welded into a frame structure;

[0038] The feeding mechanism, located on one side above the bed 1, is used to transport the glass to be drilled to the processing area;

[0039] The discharge mechanism is located on the other side above the bed 1 and is used to transport the punched glass outward. The processing area mentioned above is the position between the feeding mechanism and the discharge mechanism.

[0040] A glass positioning mechanism is located above the bed 1, at the position of the feeding mechanism. The glass positioning mechanism includes a pusher cylinder 8 and a flow bar 6 on both sides of the glass conveying direction. The telescopic ends of the pusher cylinder 8 and the flow bar 6 are higher than the conveying plane of the feeding mechanism, so that the side of the glass can contact the telescopic ends of the pusher cylinder 8 and the flow bar respectively. It also includes a blocking cylinder 7 at the end of the feeding mechanism. Its telescopic end can move up and down. When it is raised, it is higher than the glass conveying surface and is used to block the glass when it is conveyed to the predetermined position.

[0041] In this process, the glass is placed on the surface of the feeding mechanism and conveyed forward. When the glass reaches the positioning position, the blocking cylinder 7 rises to stop the glass from moving forward. Subsequently, the pushing cylinder 8 pushes the glass laterally so that one side of it fits against the flow strip 6, thereby completing the precise positioning of the glass. Specifically, during the conveying process, the glass is conveyed by rollers with one side of it attached to the flow strip 6, which can ensure that the glass block always moves along a fixed reference edge during the forward movement, avoiding deviation or tilting, improving the positional stability and final positioning accuracy during the conveying process, and providing a reliable guarantee for the subsequent laser drilling operation.

[0042] Specifically, both the feeding mechanism and the discharging mechanism include a mounting frame 3 fixed above the bed 1. A connecting frame 9 is installed above the mounting frame 3, and a conveyor 2 is installed on the connecting frame 9. In this example, the mounting frame 3 is a long strip of aluminum alloy profile, and the connecting frame 9 is connected to the mounting frame 3 by bolts. More specifically, the number of conveyors 2 in the feeding mechanism and the discharging mechanism can be designed to be different according to actual needs. In this embodiment, there are four conveyors 2 in each of the feeding mechanism and the discharging mechanism. The four conveyors 2 are set at the same height and are transported by synchronous belts and synchronous pulleys (the specific structure and principle of the conveyor 2 are conventional settings in the prior art and will not be described in detail here). More specifically, the synchronous belt in this example is a herringbone pattern synchronous belt, which has the characteristics of high conveying accuracy. The synchronous pulleys on the same side of the four conveyors 2 are driven by the same transmission shaft combined with a motor and a reducer, which further ensures the synchronous operation of the four conveyors 2. Since the mounting frame 3 is a long strip of aluminum alloy profile, in actual operation, the overall width of the conveyor 2 can be adjusted to accommodate the conveying of glass of different sizes, giving it a certain degree of flexibility.

[0043] Specifically, a gap is formed between the feeding mechanism and the discharging mechanism, and a receiving trough 4 is installed on the bed 1 at the gap position. More specifically, the receiving trough 4 is a shell-shaped structure with openings on the top and one side. In actual operation, waste material from glass drilling falls into the receiving trough 4 and is collected in a concentrated manner, and is periodically discharged outward by the staff from the opening side.

[0044] Specifically, the flow strip 6 is installed at the outer edge of the feeding mechanism, and its length direction is parallel to the conveying direction of the conveyor 2; the pusher cylinder 8 is located at the outer edge of the other side of the feeding mechanism, and there are at least two pusher cylinders 8, which are spaced apart. The flow strip 6 is used to position the glass side, and during the conveying process, the rollers on the flow strip 6 can be used to prevent the glass from being damaged. The pusher cylinder 8 is used to push the glass flexibly to improve the positioning effect.

[0045] Specifically, the blocking cylinder 7 is installed on the end side wall of the conveyor 2 of the feeding mechanism to position the glass in the direction of travel during the glass positioning process, so that the glass is straightened and facilitates the subsequent drilling operation.

[0046] It is understandable that the aforementioned pusher cylinder 8, flow bar 6, and blocking cylinder 7 can also be directly installed on the bed 1, which can also achieve the same effect of precise positioning of the glass.

[0047] Specifically, a vertically operating support cylinder 10 is installed on the bed 1 near the feed mechanism at the gap between the feeding mechanism and the discharging mechanism. A rotatable support wheel 11 is installed at the end of the telescopic rod of the support cylinder 10, which can effectively support the glass in the drilling processing area, avoid the glass from shaking due to its own weight or unstable center of gravity, and improve the stability and safety of the processing process.

[0048] Specifically, a crossbeam 12 is fixed in the middle of the bed 1, between the feeding mechanism and the discharging mechanism. The length direction of the crossbeam 12 is perpendicular to the glass conveying direction. At least two horizontal moving frames 13 that move along the length direction of the crossbeam 12 are installed on the crossbeam 12. A vertical lifting frame 14 that can move vertically along the horizontal moving frame 13 is provided on the horizontal moving frame 13. A laser drill 15 is installed on the vertical lifting frame 14. In this example, there are two horizontal moving frames 13, that is, there are also two laser drills 15, which is a dual-head laser drilling, which is used to realize synchronous drilling or alternating drilling during drilling, effectively improving processing efficiency, and is particularly suitable for the processing needs of porous and diversified glass products.

[0049] The working principle of the horizontal moving frame 13 and the vertical lifting frame 14 mentioned above is achieved by using a structure of motor, linear guide rail and lead screw (or ball screw). The driving principle is a conventional setting in the existing technology and will not be described in detail here.

[0050] Specifically, the bed 1 is equipped with a movable cantilever control panel 5, which allows the operator to adjust the control position according to actual needs, improves the convenience of operation and human-machine interaction experience, and also helps to carry out maintenance and debugging work, thereby improving the overall intelligence and humanization level of the equipment.

[0051] In actual operation, the glass to be processed is first placed manually or by a robotic arm onto the surface of the conveyor 2 of the feeding mechanism. Driven by a motor and synchronous belt transmission, the conveyor 2 slowly advances the glass into the processing area along the conveying direction. As the front end of the glass approaches the preset positioning area, the blocking cylinder 7, installed on the side wall at the end of the conveyor 2, extends, and its telescopic end rises to a height higher than the glass conveying surface, thereby preventing the glass from moving forward and achieving forward limiting. At this time, the pushing cylinder 8, located on one side of the glass, begins to operate, its telescopic end extending and pushing the glass laterally, causing the side of the glass to press tightly against the rollers on the flow strip 6 on the other side, completing lateral limiting. The flow strip 6 provides smooth guidance while preventing the glass from being scratched or broken. The entire positioning process is fast and precise, ensuring the glass remains stable within the drilling area. After positioning, the blocking cylinder 7 descends, and the glass is conveyed to the processing area. Two laser drills 15 mounted on the crossbeam 12 begin operation. Each laser drill 15 moves along the length of the crossbeam 12 via a corresponding horizontal moving frame 13. Simultaneously, the vertical lifting frame 14 controls the height adjustment of the drilling heads, ensuring precise alignment with the target position on the glass. The two drilling heads can be set to synchronous or alternating drilling according to actual process requirements, significantly improving the efficiency of multi-hole processing, making it particularly suitable for high-volume, complex-structured glass product drilling applications. The operator can set parameters, retrieve programs, monitor status, and manually intervene via the cantilevered operating table on the machine bed 1. The position of the operating table can be flexibly adjusted according to actual operational needs, enhancing the comfort and convenience of human-machine interaction.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
