[0002] In the field of electronic information display, the substrate glass used needs to undergo further precision cutting processing. On the one hand, this is to meet the standard size of the supplied substrate glass required by customers. On the other hand, precision cutting can eliminate cracks and chipping on the four sides of the substrate glass, reduce the difficulty and time of subsequent grinding and polishing processing, and improve processing efficiency.

[0003] In the current precision cutting process of substrate glass, the cutting blade is moved up and down by a power mechanism to cut the substrate glass.

[0004] However, when the blade contacts the glass surface, it generates an impact force. This impact force can not only damage the sharpness and teeth of the blade and reduce the service life of the blade wheel, but may also cause new cracks and chipping of the substrate glass, affecting the product yield. Utility Model Content

[0005] One of the technical problems that this disclosure aims to solve is that the rigid drive of existing glass cutting blades not only damages the sharpness and teeth of the blades and reduces the service life of the cutting wheel, but may also cause new cracks and chipping of the substrate glass, affecting product yield.

[0027] Through the above technical solution, the cutting head provided in this disclosure achieves the motion drive of the cutter wheel assembly along a first direction through the cooperation of a drive assembly and a buffer drive assembly.

[0040] Glass substrates have applications in numerous fields, such as displays, photovoltaics, fiber optic communications, semiconductor manufacturing, and biochips. Consequently, the production dimensions of glass substrates are not fixed and need to be cut according to customer requirements to meet the specific product needs of different fields. Current precision cutting processes for glass substrates involve a motor driving a cutting head to move up and down to cut the glass substrate. The entire process involves impact-type contact and cutting actions. In particular, the impact force generated when the cutting head first contacts the glass surface can damage the sharpness and teeth of the cutting head, reduce the lifespan of the cutting wheel, and may even cause new cracks or chipping in the glass substrate, affecting product yield.

[0041] The cutting head provided in this embodiment drives the cutter wheel assembly through the joint action of the drive component and the buffer drive component, which improves the flexibility and complementarity of the drive. Furthermore, the compressible nature of the drive space within the buffer drive component allows for force absorption when the cutter wheel contacts the workpiece to be cut, thereby achieving buffering and soft contact between the cutter wheel assembly and the workpiece to be cut, effectively protecting the cutter wheel assembly and extending its service life.

[0042] Example 1

[0043] Reference Appendix Figure 1 This embodiment discloses a cutting head, which includes a base 1, a driving component 2, a buffer frame 3, a buffer driving component 4, and a cutting wheel assembly 5. A movable part 6 is slidably disposed on the base 1 along a first direction a, where the first direction a is the height direction of the base 1. The driving component 2 is connected to the movable part 6 to drive the movable part 6 to reciprocate relative to the base 1 along the first direction a. The buffer frame 3 is disposed on the movable part 6 to reciprocate with the movable part 6 relative to the base 1 along the first direction a. The buffer driving component 4 is disposed on the buffer frame 3, and its driving end is disposed along the first direction a. The cutting wheel assembly 5 is fixed to the driving end of the buffer driving component 4 and is used to cut a workpiece (not shown in the figure). During the movement of the cutting wheel assembly 5 along the buffer frame 3 along the first direction a, a first driving space is formed within the buffer driving component 4, generating a first driving tendency along the first direction a. When the cutting wheel assembly 5 moves along the first direction a to contact the workpiece, the first driving space is compressed in the opposite direction of the first direction a.

[0044] Specifically, to address the problem that the rigid drive of existing glass cutting blades not only damages the sharpness and teeth of the blade and reduces the service life of the cutting wheel, but may also cause new cracks and chipping of the substrate glass, affecting product yield, the cutting blade provided in this embodiment controls the high-precision movement of the cutting wheel assembly 5 in the first direction a through the drive assembly 2. When the cutting wheel assembly 5 contacts the workpiece to be cut, the buffer drive provides buffering, achieving buffered soft contact. This not only protects the cutting wheel assembly 5 and extends its service life, but also effectively ensures the product quality of the workpiece to be cut, avoiding overcutting, breakage of the workpiece, or burrs.

[0045] The cutting head provided in this embodiment can be used on both automatic and manual cutting devices; correspondingly, the cutter head in this embodiment can be adapted to cut plate-shaped products such as substrate glass and plates.

[0046] The first direction 'a' can be designed and adjusted according to actual cutting needs. For example, it can be a direction perpendicular to the horizontal plane or a direction parallel to the horizontal plane in actual use.

[0047] The base 1 is a rigid structure, which can be, but is not limited to, a plate structure, a frame structure, a cylindrical structure, etc. It serves as the mounting carrier for the buffer frame 3 and the moving part 6, and also as the connection medium between the cutting head and the cutting device or the entire cutting system. In this embodiment, a connection area can be provided on the side of the base 1 away from the moving part 6, and the connection method can be, but is not limited to, screwing, snap-fitting, welding, etc. The size and shape of the base 1 in this embodiment can be designed and adjusted according to actual needs, and are not limited here. Correspondingly, sliding parts 11 such as slide rails and slide tracks can be provided on the base 1 to cooperate with the moving part 6 to achieve reciprocating motion in the first direction a. Correspondingly, the moving part 6 is a rigid structure, which can be, but is not limited to, a plate structure, a frame structure, a block structure, etc. The moving part 6 can be adapted to the base 1 to provide sliding parts 11 such as sliders and pulleys; it is understood that slide rails and slide tracks can also be provided on the moving part 6, and sliders and pulleys can be adapted to the base 1.

[0048] The drive assembly 2 drives the moving part 6 to move along the first direction a. The drive assembly 2 can be a combination of a drive motor 21 and a lead screw 22. The lead screw 22 extends along the first direction a and is threadedly engaged with the moving part 6. The drive motor 21 is fixedly mounted on the end of the lead screw 22 away from the moving part 6, and the drive motor 21 is rotatably connected to the lead screw 22. The drive motor 21 can be, but is not limited to, a servo motor. It can be connected to or attached to the cutting device or the entire cutting system, as long as it remains fixed and does not affect its drive of the lead screw 22. There can be one or two lead screws, which can be designed and adjusted according to actual needs, and will not be elaborated here. In this embodiment, the combination of the drive motor 21 and the lead screw 22 achieves direct and rapid drive of the moving part 6, or rather, the cutter wheel assembly 5, enabling it to move precisely along the first direction a to the cutting position or cutting height. The drive motor 21 can provide continuous feed force, maintaining continuous and stable drive.

[0049] The buffer frame 3 is a rigid structure that provides mounting positions for the buffer assembly 4 and the cutter wheel assembly 5. The buffer frame 3 can be, but is not limited to, a frame structure, a cylindrical structure, etc. In this embodiment, the buffer frame 3 can be configured as a structure with a accommodating space to accommodate the buffer drive assembly 4, ensuring consistent appearance, avoiding exposure of the internal structure and affecting aesthetics, and effectively preventing dust, particles or debris from affecting the buffer drive assembly 4, thus effectively protecting the buffer drive assembly 4 and extending its service life.

[0050] The buffer drive assembly 4 has a driving function along the first direction a. It can also generate a variable first drive space during the driving process to absorb and buffer the contact or collision force between the cutter wheel assembly 5 and the workpiece to be cut. In this embodiment, the buffer drive assembly 4 can be, but is not limited to, a buffer cylinder or a pneumatic-hydraulic damping cylinder. Both buffer cylinders and pneumatic-hydraulic damping cylinders can generate a first drive space when the driving stroke has not reached its maximum stroke. Compressed gas or hydraulic oil is injected into the first drive space. In this state, the driving end of the buffer drive assembly 4, i.e., the piston rod, receives a force in the opposite direction of the cutter wheel assembly 5 along the first direction a, i.e., the contact or collision force generated when the cutter wheel assembly 5 contacts the workpiece to be cut. Therefore, the first drive space... Compression is applied to a certain extent in the opposite direction of the first direction a to absorb the resistance or collision force. It is easy to understand that when the buffer drive assembly 4 performs buffering in the opposite direction of the first direction a, the drive assembly 2 continuously drives the moving part 6 or the cutter wheel assembly 5 in the first direction a. As a result, the contact between the cutter wheel assembly 5 and the workpiece to be cut is transformed into a buffered soft contact. Then, as the first drive space of the buffer drive assembly 4 gradually increases in the first direction a under the action of the drive source until the maximum stroke is reached, the cutter wheel assembly 5 presses into the workpiece to be cut at a preset depth. The drive assembly 2 stops driving in the first direction a. Subsequently, continuous cutting of the workpiece in any direction can be achieved by driving the entire cutting device or cutting system. In this embodiment, a drive assembly 2 and a buffer drive assembly 4 are provided together. The drive assembly 2 can control the rapid, direct and continuous movement of the cutter wheel assembly 5 along the first direction a. The buffer drive assembly 4 can provide buffering when the cutter wheel assembly 5 contacts the workpiece to be cut, preventing hard contact and avoiding overcutting or breakage of the workpiece. Moreover, the buffer drive assembly 4 does not affect the continuous drive of the drive assembly 2 when providing buffering, which can effectively improve the cutting speed and prevent the workpiece to be cut from deforming under hard contact and rapid cutting conditions.

[0051] The cutter wheel assembly 5 can be in the form of a cutter wheel and a corresponding motor drive mechanism. The cutter wheel assembly 5 can be connected to the drive end of the buffer drive assembly 4 by screwing or welding.

[0052] It should be noted that in this embodiment, the drive motor 21, the buffer drive component 4, and the aforementioned motor drive mechanism can be automatically controlled by a unified controller, or they can be semi-automatically controlled in conjunction with the operator and the controller. When the drive motor 21, the buffer drive component 4, and the aforementioned motor drive mechanism are automatically controlled by a unified controller, the rotation parameters and rotation duration of the drive motor 21, the drive parameters of the buffer drive component 4, and the rotation parameters of the motor drive mechanism can be preset in the controller. In conjunction with the position sensor or distance sensor set on the cutter wheel assembly 5, the positioning information of the drive motor 21 relative to the workpiece to be cut can be detected, thereby accurately controlling the start and stop of the drive motor 21. When the drive motor 21, the buffer drive component 4, and the aforementioned motor drive mechanism are semi-automatically controlled in conjunction with the operator and the controller, the operator can control the start and stop of the drive motor 21 by observing the movement state and position of the cutting head.

[0053] As described above, the cutting head provided in this disclosure drives the movement of the cutting wheel assembly 5 along the first direction a through the cooperation of the driving component 2 and the buffer driving component 4. Simultaneously, the variable driving space of the buffer driving component 4 absorbs and buffers the force exerted when the cutting wheel assembly 5 contacts the workpiece, achieving soft contact between the cutting wheel assembly 5 and the workpiece. This effectively protects the sharpness and integrity of the cutting teeth of the cutting wheel assembly 5, extends its service life, and effectively ensures the product quality of the workpiece. This effectively solves the problem that the rigid drive of existing glass cutting heads not only damages the sharpness and teeth of the cutting head and reduces the service life of the cutting wheel, but may also cause new cracks and chipping in the substrate glass, affecting product yield.

[0054] In this article, the term "and / or" is merely a description of the relationship between related objects, identifying three possible relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included simultaneously, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0055] In some embodiments, refer to the appendix Figure 3 In this embodiment, the cutting head is provided in a specific implementation where the buffer drive component 4 is a buffer cylinder. During the movement of the cutter wheel assembly 5 along the buffer frame 3 in the first direction a, the buffer cylinder is in the middle stroke and has the first drive space, so that when the cutter wheel assembly 5 moves along the first direction a to contact the workpiece to be cut, the first drive space can be compressed.

[0056] It is understandable that, in order to achieve the buffering performance of the buffer drive assembly 4, it can be configured as a buffer cylinder in this embodiment, which can be, but is not limited to, a one-way cylinder, a two-way cylinder, etc. When the drive motor 21 drives the buffer frame 3 toward the workpiece to be cut, the buffer cylinder can also start to be driven by the air source. That is, the air source drives the piston in the buffer cylinder along the first direction a to gradually increase the first drive space. When the cutter wheel assembly 5 contacts the workpiece to be cut, the buffer cylinder has not reached its maximum stroke, and the piston inside is in a state where it can move freely in both directions. At this time, the cutter wheel assembly 5 is subjected to the resistance or collision force of the workpiece to be cut in the opposite direction of the first direction a. The force can be transmitted to the piston to resist or squeeze the piston in the opposite direction of the first direction a, thereby absorbing the force when the cutter wheel assembly 5 contacts the workpiece to be cut. The resistance action of the cutter wheel assembly 5 toward the workpiece to be cut is buffered to achieve soft contact, protecting the cutter wheel assembly and improving the yield of the workpiece to be cut. Product quality; and it is understood that in this embodiment, when the cutter wheel assembly 5 contacts the workpiece to be cut, the drive motor 21 continues to drive along the first direction a until the cutter wheel assembly 5 reaches a predetermined pressing depth relative to the workpiece to be cut; the cutter wheel assembly 5 reaching the predetermined pressing depth can be determined by setting the maximum stroke of the buffer cylinder, or by the buffer cylinder reaching the set working pressure, because when the buffer cylinder reaches the set working pressure and the piston in the buffer cylinder reaches the maximum stroke, it means that it will maintain a constant state for ejection. In this state, the cutting head can be continuously cut in any direction by controlling the cutting device or the cutting system as a whole; the above content can be obtained through experiments, and will not be elaborated in this embodiment.

[0057] Further, see Appendix Figure 3 In this embodiment, the cutting head also includes a connector 7. The connector 7 is disposed between the buffer drive assembly 4 and the cutter wheel assembly 5 along the first direction a. The connector 7 has a specified length along the first direction a to extend the drive stroke of the buffer drive assembly 4. The end of the connector 7 facing away from the buffer drive assembly 4 is provided with a connecting end, which is used to detachably connect to the cutter wheel assembly 5.

[0058] Understandably, to simplify the connection and installation of the cutter wheel assembly 5 and the buffer cylinder, a connector 7 is provided in this embodiment. The connector 7 is a rigid structure, which can be a rod-shaped structure, a cylindrical structure, a frame structure, etc. Correspondingly, one end of the connector 7 can be provided with an internal thread adapted to connect to the piston rod of the buffer cylinder, and the other end of the connector 7 can be provided with a connecting end. The connecting end can be, but is not limited to, a plate-shaped, pin-shaped, etc., and can be, but is not limited to, connected to the cutter wheel assembly 5 by bolts, for example, attached... Figure 3As shown in the diagram, the connecting end can also be a slot or other structure, which is not limited here. In this embodiment, the size of the connecting piece 7 in the first direction a can be designed and adjusted, for example, by 10-20cm. This can extend the driving stroke of the buffer cylinder and reduce the driving stroke of the drive motor 21. For example, when the connecting piece 7 is not set, the drive motor 21 may need to drive the buffer frame 3 to move 1m along the first direction a so that the cutter wheel assembly 5 contacts the workpiece to be cut. When the connecting piece 7 is set, the driving distance of the drive piece 21 for the buffer frame 3 along the first direction a can be reduced by the length of the connecting piece 7, thereby effectively reducing energy consumption and lowering production costs.

[0059] Further, see Appendix Figure 3 The cutting head provided in this embodiment further includes a movable connecting rod 8 in a specific implementation; at least two movable connecting rods 8 are spaced apart along the first direction a to correspond to the two ends of the connector 7 along the first direction a respectively, and the two ends of the movable connecting rod 8 are respectively rotatably connected to the buffer frame 3 and the connector 7.

[0060] Understandably, to ensure the stability of the connector 7 during driving and force transmission, a movable connecting rod 8 can be provided in this embodiment. The movable connecting rod 8 is a rigid structure, and its length can be designed and adjusted according to the internal space of the actual buffer frame 3. At least two movable connecting rods 8 are spaced apart at both ends of the connector 7 along the first direction a, forming a parallel linkage mechanism. When the buffer cylinder drives the cutter wheel assembly 5 to move along the first direction a through the connector 7, the buffer cylinder is the only driving force. Therefore, when the connector 7 reciprocates in the first direction a, it may sway or deviate, affecting the driving stability of the cutter wheel assembly 5. In this embodiment, the movable connecting rod 8 can serve as an auxiliary support. Alternatively, a guide rod structure can be used, which can achieve limiting and guiding through the rotation of both ends, strictly restricting the movement of the connecting piece 7 to the first direction a to prevent shaking. The movable connecting rod 8 can also work synchronously with the buffer cylinder to avoid jamming or tilting caused by the unilateral drive of the buffer cylinder. When the buffer cylinder is driven to move by the cutting device or the entire cutting system, it may be subjected to external forces and vibrate. At this time, the movable connecting rod 8 can also share part of the load pressure of the buffer cylinder and improve the rigidity of the system. In this embodiment, the setting of the movable connecting rod 8 can also limit the movement range or maximum stroke of the connecting piece 7 along the first direction a, and work in coordination with the buffer cylinder for stable driving.

[0061] In some embodiments, the cutting head provided in this embodiment is equipped with a regulating valve (not shown in the figure) on the buffer cylinder.

[0062] It is understandable that, in order to improve cutting quality, a regulating valve can be installed on the buffer cylinder in this embodiment. The regulating valve can be, but is not limited to, a one-way throttle valve, a two-way throttle valve, etc. The setting of the regulating valve can precisely control the working pressure of the buffer cylinder as needed. For example, the opening of the regulating valve can be adjusted according to the preset working pressure, that is, the maximum stroke of the buffer cylinder can be adjusted. Of course, the maximum stroke or working pressure can be determined according to the pressing depth or cutting depth of the workpiece to be cut. Thus, by setting the regulating valve, the working pressure of the buffer cylinder can be precisely adjusted, and the pressing amount of the cutter wheel assembly 5 can be precisely controlled, thereby improving the cutting quality and product yield.

The connection method can be, but is not limited to, screwing, snap-fitting, welding, etc., and it moves to the cutting position with the robotic arm or power arm. This setting can be easily understood by those skilled in the art, and will not be repeated here.

[0066] The cutting device provided in this disclosure achieves the motion drive of the cutter wheel assembly 5 along the first direction a through the cooperation of the drive component 2 and the buffer drive component 4 in the cutting head. At the same time, the variable drive space of the buffer drive component 4 is used to absorb and buffer the force when the cutter wheel assembly 5 contacts the workpiece to be cut, so as to achieve soft contact between the cutter wheel assembly 5 and the workpiece to be cut, effectively protecting the sharpness and integrity of the cutter teeth of the cutter wheel assembly 5, extending the service life of the cutter wheel assembly 5, reducing the replacement frequency of the cutting head, improving the overall production efficiency, reducing production costs, and effectively ensuring the product quality of the workpiece to be cut.

[0071] The cutting system disclosed herein uses the cooperation of the drive component 2 and the buffer drive component 4 in the cutting head to drive the movement of the cutter wheel assembly 5 along the first direction a.
