[0002] In existing glass cutting technology, laminated glass and ordinary glass are mainly processed using separate specialized equipment. Laminated glass cutting often employs a step-by-step process of cutting, heating separately, and cutting the adhesive layer. This process is prone to problems such as misalignment between the cutting kerf and the heating position, resulting in uneven softening of the adhesive layer, glass breakage, or uneven cuts of the adhesive layer. Ordinary glass cutting equipment cannot cut laminated glass. Therefore, existing glass cutting technology lacks dual-mode cutting equipment compatible with both laminated and ordinary glass, forcing them to be cut on different equipment. Furthermore, existing laminated glass cutting equipment suffers from issues such as misalignment between the cutting kerf and the heating position, leading to uneven softening of the adhesive layer, glass breakage, or uneven cuts of the adhesive layer.

S500: After heating is complete, the control unit controls the stretching device to work with the first or second conveyor to pull the laminated glass a preset distance to one or both sides with the cutting seam as the center, so that the laminated glass forms a controllable gap along the cutting seam.

[0021] The specific structural or functional descriptions disclosed in the embodiments of the present invention are illustrative only for the purpose of explaining embodiments of the concepts according to the present invention, and embodiments of the concepts according to the present invention can be implemented in various forms. Furthermore, it should not be construed as limited to the embodiments described herein, and it should be understood to include all modifications, equivalents, and substitutions contained within the spirit and scope of the present invention.

[0022] In this invention, terms such as "first" and / or "second" may be used to describe various components, but these components are not limited to those terms. The terms are used only for the purpose of distinguishing the various components.

[0023] Throughout this specification, the same reference numerals denote the same parts. In the following description, technical terms are used only to explain particular embodiments and not to limit the invention. In this specification, singular terms may include plural forms unless specifically mentioned. The invention will now be described in detail with reference to the accompanying drawings.

[0024] Example 1: A dual-mode cutting method compatible with both laminated glass and ordinary glass, the cutting method comprising: S100: When the glass to be cut is transported to the cutting platform, the glass type identification module identifies the type of glass to be cut, and the control unit switches the processing mode according to the identification result; the glass to be cut is transported to the designated position and positioned and fixed by a positioning and fixing mechanism located on the top surface of the first conveyor or the second conveyor, wherein the positioning and fixing mechanism is a clamp or a vacuum adsorption device; if it is ordinary glass, proceed to step S200, and if it is laminated glass, proceed to step S300; S200: The control unit starts the first gantry support above the conveyor and the first glass cutting head on the support to move horizontally to cut ordinary glass on one side; at the same time, it controls the second gantry support, the second cutting head, the heating device, and the stretching device below the end of the conveyor to remain in a dormant state. S300: The control unit starts the first gantry support and the first glass cutting head to move horizontally to cut the top surface of the laminated glass; at the same time, it starts the second gantry support and the second cutting head below the end of the conveyor to move horizontally to cut the bottom surface of the laminated glass to form a cutting slit; S400: The control unit starts the heating device and the stretching device. The heating device heats the cutting kerf, and the stretching device fixes the glass to be cut by adsorption or clamping, applying a pre-tension to the cutting kerf. S500: After heating is complete, the control unit controls the stretching device to work with the first or second conveyor to pull the laminated glass a preset distance to one or both sides with the cutting seam as the center, so that the laminated glass forms a controllable gap along the cutting seam. S600: The softened adhesive layer is cut along the gap by an adhesive layer cutting blade integrated into the first glass cutting head or the second glass cutting head, thus completing the laminated glass cutting.

[0025] There are two ways to implement step S400. The first way is that step S400 includes: S410: Keep the glass to be cut stationary; S411: The heating device moves to the area below or above the cutting seam for heating; the movement of the heating device can be either horizontal or vertical.

[0026] S412: The stretching device moves horizontally to below or above the cutting seam, and fixes the side of the cutting seam to be stretched by a suction cup or clamp, while the control unit controls the positioning and fixing mechanism of the side to be stretched to release the fixation. S413: The tensioning device applies pre-tension to the cutting seam according to the set control parameters.

[0027] The second method, step S400, includes: S420: Keep the heating device in place; S421: The control unit controls the conveyor to release the fixing of the glass to be cut, transport the glass to be processed to the area below or above the heating device, and position the cutting kerf in the heating area, and the heating device heats the cutting kerf. S422: The stretching device moves horizontally to below or above the cutting seam, and fixes the side of the cutting seam to be stretched by a suction cup or clamp, while the control unit controls the positioning and fixing mechanism of the side to be stretched to release the fixation. S423: The tensioning device applies pre-tension to the cutting seam according to the set control parameters.

[0028] In both of the above implementation methods, the tensioning device is equipped with a tension sensor. The tension sensor detects changes in pretension in real time and transmits the signal to the control unit. The control unit adjusts the heating temperature and heating time of the heating device according to the changes in pretension to adapt to different adhesive layer types.

[0029] The control unit presets the pre-tension threshold range corresponding to different adhesive layer types. When the pre-tension detected by the tension sensor is lower than the threshold, the control unit increases the heating temperature of the heating device or extends the heating time to further soften the adhesive layer. When the pre-tension reaches the threshold and remains stable, the control unit maintains the current heating parameters to ensure that the applied pre-tension matches the softening state of the adhesive layer.

[0030] Example 2: A multi-functional laminated glass cutting machine is provided for implementing the dual-mode cutting method for laminated glass and ordinary glass as described in this claim. The multi-functional laminated glass cutting machine includes a conveyor, a glass type identification module, a control unit 3, a heating device 107, and a stretching device 106. The conveyor is arranged sequentially along the glass conveying direction as a first conveyor 1 and a second conveyor 2. A positioning and fixing mechanism 105 is provided on the top surface of either the first conveyor 1 or the second conveyor 2 for positioning and fixing the glass to be cut. The glass type identification module is located on the side of either the first conveyor or the second conveyor for identifying the glass type and transmitting a signal to the control unit 3. A first gantry support 103 is provided above the conveyor, and a second gantry support 109 is provided below the end of either the first conveyor 1 or the second conveyor 2. Both the first gantry support 103 and the second gantry support 109 are equipped with horizontally movable glass cutting heads, one of which is equipped with an adhesive layer cutting blade. The adhesive layer cutting blade and the blade of the glass cutting head are connected. The base is detachably connected, and the blade holder can be equipped with an independent drive component, which is electrically connected to the control unit. The control unit triggers the adhesive layer cutting blade to move according to the controllable gap formation signal. The drive component drives the adhesive layer cutting blade to move smoothly along the gap extension direction to complete the adhesive layer cutting. Alternatively, the glass cutting head can be driven by its own motor to move the glass cutting head and the adhesive layer cutting blade together for cutting. The heating device 107 and the stretching device 106 are located above or below the end of the first conveyor 1 or the second conveyor 2. The heating device 107 is used to heat the cutting seam, and the stretching device 106 is used to fix the side of the cutting seam to be pulled and cooperate with the conveyor to pull the glass to be cut, pulling a preset distance to one or both sides with the cutting seam as the center, so that the laminated glass forms a controllable gap along the cutting seam. The control unit 3 is electrically connected to the conveyor, the glass type identification module, the heating device 107 and the stretching device 106, and is used to control the conveyor, the glass type identification module, the heating device and the stretching device to work together.

[0031] The three-coordinate or two-coordinate motion structure of the gantry is existing technology for gantry mechanical devices, and its structure and operating principle are well known to those skilled in the art. The specific structure of the first gantry support 103 and the second gantry support 109 driving the glass cutting head will not be described in detail here.

[0032] The positioning and fixing mechanism 105 is a clamp or vacuum adsorption device, which can adaptively switch between fixed and released states under the control of the control unit, and complete the application of pre-tension in conjunction with the tensioning device. The positioning and fixing mechanism is available in two types: clamp type and vacuum adsorption type. The clamp type structure consists of symmetrically arranged grippers or blocks, a drive assembly, and a mounting base. The mounting base is fixed to the frame on the side of the top surface of the first or second conveyor, and is located inside the first gantry support. The mounting height of the mounting base maintains an appropriate distance from the top surface of the conveyor, ensuring that the grippers or blocks can accurately act on the glass edge when moving, and without interfering with the movement path of the first gantry support. For example, the mounting base is fixed to the frame on the side of the top surface of the first or second conveyor, and is located inside the first gantry support. A linear module or cylinder is fixed to the top of the mounting base, and grippers or blocks are fixed to the moving parts of the linear module or cylinder. The grippers or blocks are driven by the linear module or cylinder. The clamping block positions the glass to be cut. A buffer protective layer can be provided at the contact point between the clamping jaws or clamping block and the glass to prevent the glass from breaking. The effect of the compression of the adhesive layer on positioning can be adjusted by obtaining the actual adjustment value through multiple experiments. The suitability of the buffer protective layer can be determined by multiple experiments to determine its material hardness and contact area, ensuring that positioning will not damage the glass surface and can provide stable clamping force. This is a commonly used positioning method in automated processing and will not be elaborated here. Another example is that the clamping jaws are connected to the mounting base through a hinge shaft, and the drive component adopts a pneumatic or hydraulic drive method. Its output end is connected to the clamping jaw transmission and electrically connected to the control unit. The vacuum adsorption structure consists of an adsorption panel, an air channel, and a vacuum generator. The adsorption panel is embedded in the top surface of the conveyor. The panel has evenly distributed adsorption holes. One end of the air channel is connected to the adsorption hole, and the other end is connected to the vacuum generator. The vacuum generator is electrically connected to the control unit.

[0033] The control unit, based on the processing requirements, drives the clamping mechanism to open and close the grippers, or controls the vacuum generator to start and stop, thus fixing and releasing the glass to be cut. When the tensioning device applies pre-tension, it controls the positioning and fixing mechanism on the side to be pulled to release the fixation in a timely manner, cooperating with the tensioning device to complete the application of pre-tension, ensuring positioning stability and process coordination. The first conveyor 1 and the second conveyor 2 are driven independently. Their drive components are a combination of servo motors and reducers, which are electrically connected to the control unit. The control unit can precisely adjust the conveying speed and displacement of the conveyors. The control unit 3 controls the tensioning device 106 to work with the first conveyor 1 and the second conveyor 2 to pull to one side or both sides with the cutting seam as the center.

[0034] The glass type identification module can be an optical identification sensor, a thickness detection sensor, or a manual input module. The identification signal obtained by the glass type identification module is transmitted to the control unit in real time to trigger the corresponding processing mode. Specifically, the glass type identification module is installed on the frame on the side of the first or second conveyor, located in the upstream area of ​​the glass conveying path. Its detection end faces the glass conveying surface and can directly collect the optical characteristics or thickness information of the glass. The collected signal is transmitted to the control unit in real time through a wire or wireless transmission module. The control unit has a built-in preset glass type feature database. After determining the glass type through comparative analysis, the corresponding processing mode is triggered. This automatic acquisition can also be replaced by manual input of the glass type through the control panel. The directly input data signal is transmitted to the control unit in real time through a wire or wireless transmission module. The control unit has a built-in preset glass type feature database. After determining the glass type through comparative analysis, the corresponding processing mode is triggered.

[0035] The heating device 107 moves horizontally via a linear module or cylinder, or swings vertically via a swing mechanism. The heating device has a built-in temperature sensor that is electrically connected to the control unit to provide real-time feedback on the heating temperature. The control unit performs closed-loop adjustment based on the preset temperature value corresponding to the type of adhesive layer. The stretching device is equipped with a tension sensor, which is integrated into the connection between the stretching device and the suction cup and is electrically connected to the control unit.

[0036] The swing mechanism of the heating device 107 is driven by a rotary cylinder 5 or a motor; the linear module or cylinder and the rotary cylinder or motor are electrically connected to the control unit 3. The control unit obtains the cutting seam position by receiving the positioning sensor signal of the glass cutting head, and then drives the relevant actuators to adjust the position of the heating device to ensure that the heating area is precisely aligned with the cutting seam, and adaptively adjusts the position of the heating device according to the cutting seam position.

[0037] Specifically, the horizontal movement structure of the heating device consists of a linear module or a cylinder fixedly connected to the heating device body. When a linear module is used, the linear module has a guide rail and an adapter slider extending along the glass conveying direction. The slider is rigidly connected to the heating device, and the end or side of the guide rail is equipped with a position detection component electrically connected to the control unit. When a cylinder is used, the piston rod of the cylinder is directly fixed to the heating device, and the cylinder body is fixed at a preset position on the equipment frame. The cylinder's air intake and exhaust circuits are linked to the control unit via an electromagnetic reversing valve. Based on the cutting seam positioning signal, the control unit drives the linear module slider to slide along the guide rail or controls the cylinder piston rod to extend and retract, causing the heating device to move smoothly in the horizontal direction. The position detection component provides real-time feedback on the heating device's position information, ensuring that it accurately stops at the heating area corresponding to the cutting seam.

[0038] The vertical swing structure of the heating device consists of a swing mechanism hinged to the heating device body. The swing mechanism includes a rotary cylinder 5 or a motor, a rotating shaft, and a connecting rod assembly 6. The rotary cylinder or motor is fixed to the equipment frame, and its output end is connected to the rotating shaft via a coupling. One end of the connecting rod assembly is fixed to the rotating shaft, and the other end is hinged to the side wall of the heating device. A limiting component for limiting the swing angle is provided at the bottom or side of the heating device, and this limiting component is electrically connected to the control unit. According to the cutting seam position signal, the control unit drives the rotary cylinder or motor to rotate the rotating shaft, which in turn pulls the heating device to swing around the hinge point in the vertical plane via the connecting rod assembly. The limiting component detects the swing position in real time and provides feedback signals, so that the heating device swings precisely to the designated heating position above or below the cutting seam, ensuring that the heating area completely covers the cutting seam.

[0039] Preferably, the tension sensor is a strain gauge sensor.

[0040] The glass cutting heads of the first gantry support 103 and the second gantry support 109 are driven by servo motors or linear guides. The servo motors are electrically connected to the control unit. The control unit drives the servo motors to move the glass cutting heads smoothly along the linear guides according to the preset cutting path signal, so as to achieve precise cutting.

[0041] In practical use: The control unit first determines the pulling method (single-sided or double-sided) and the preset distance based on the signal from the glass type identification module, the cutting seam positioning information, and the adhesive layer type. Then, it sends a coordinated instruction to the relevant components: First, it controls the positioning and fixing mechanism on the side of the cutting seam to be pulled to release the fixing of the glass to be cut. At the same time, it instructs the stretching device to accurately fix the side of the cutting seam to be pulled by the suction cup or clamp. If it is double-sided pulling, it controls the first conveyor and the second conveyor to drive independently in opposite directions, and synchronously cooperates with the stretching device to apply a stable pulling force, pulling synchronously to both sides with the cutting seam as the center. If it is single-sided pulling, it controls one of the conveyors to drive, and the stretching device to apply a pulling force to pull to one side. During the pulling process, the tension sensor on the stretching device transmits the pre-tension change signal to the control unit in real time. The control unit dynamically fine-tunes the drive speed of the conveyor and the tension output of the stretching device to ensure that the pulling process is smooth and controllable. Finally, it makes the laminated glass form a controllable gap with a uniform width along the cutting seam, providing stable conditions for the subsequent adhesive layer cutting process.

[0042] Although preferred embodiments of the invention have been described for illustrative purposes, those skilled in the art will understand that various modifications, additions, and substitutions are possible without departing from the scope and spirit of the invention as disclosed in the appended claims. Therefore, the embodiments of the invention are disclosed merely for illustrative purposes and should not be construed as limiting the invention.
