[0029] Please see Figures 1 to 6 This utility model provides a technical solution: a glass cutting device for display screen production, comprising a protective cover 2, a drive assembly, a rotating assembly, and a sliding seat 7. The protective cover 2 has a rectangular cylindrical structure, and the sliding seat 7 is longitudinally slidably installed inside the protective cover 2, and the sliding seat 7 is detachably installed from the protective cover 2. The drive assembly includes a motor 11, which is fixedly installed inside the protective cover 2. The rotating assembly includes a connecting shaft 4 and a cutting blade 3. The connecting shaft 4 is rotatably installed on the sliding seat 7, and the connecting shaft 4 is detachably installed from the sliding seat 7. The cutting blade 3 is fixedly installed at one end of the connecting shaft 4. The motor 11 is drively connected to the connecting shaft 4, and the motor 11 drives the connecting shaft 4 to rotate.

[0030] The protective cover 2 primarily protects the internal transmission and rotating components, preventing the entry of external dust, debris, and other impurities, while also providing a stable external support structure for the device. The sliding seat 7 is longitudinally slidably installed inside the protective cover 2. This design allows the sliding seat 7 to slide up and down within the protective cover 2, facilitating the installation and replacement of the cutting blade 3. The motor 11 is the core component of the drive assembly. The motor 11 drives the connecting shaft 4 to rotate via a transmission connection, thereby enabling the rotating cutting function of the cutting blade 3. The sliding function of the sliding seat 7 is one of the key structural features of this invention for achieving rapid replacement of the cutting blade 3. Through a simple sliding operation, the sliding seat 7 can be moved out of the protective cover 2, exposing the connecting shaft 4, facilitating the replacement of the cutting blade 3. The cutting blade 3 cuts glass and is a crucial component for achieving the cutting function.

[0031] Specifically, the drive assembly also includes a second gear 9 and a connecting plate 10. The connecting plate 10 is fixedly installed on the inner top wall of the protective cover 2. The second gear 9 is rotatably installed on the connecting plate 10. The motor 11 is fixedly installed on the outer side wall of the connecting plate 10. The output shaft of the motor 11 is connected to the second gear 9 for transmission, and the motor 11 drives the second gear 9 to rotate.

[0032] More specifically, the rotating assembly also includes a first gear 8, which is mounted on the outer side wall of the connecting shaft 4 and the two are fixedly connected. The first gear 8 meshes with the second gear 9.

[0033] When the motor 11 starts, its output shaft drives the second gear 9 to rotate. The second gear 9 pushes the first gear 8, which meshes with it, to rotate. The first gear 8 drives the connecting shaft 4 to rotate. The connecting shaft 4 drives the cutting blade 3 to rotate. The high-speed rotating cutting blade 3 can cut the glass used in the production of the display screen.

[0034] Specifically, at least one groove 12 is provided on the inner side wall of the protective cover 2, and the sliding seat 7 is longitudinally slidably connected to the protective cover 2 through the groove 12.

[0035] The design of the slide groove 12 ensures the stable sliding of the slide block 7 within the protective cover 2, avoiding shaking and jamming during the sliding process. The design of the slide groove 12 allows the slide block 7 to slide stably up and down within the protective cover 2, facilitating the replacement of the cutting blade 3.

[0036] More specifically, the sliding seat 7 includes a base plate 701, a side plate 702, and two support plates 703. The side plate 702 and the two support plates 703 are all fixedly installed on the upper surface of the base plate 701, and the two support plates 703 are arranged laterally. The upper part of the support plate 703 has a mounting groove. This structural design gives the sliding seat 7 sufficient strength and stability to withstand the weight of the connecting shaft 4 and the cutting blade 3 on it, ensuring that the sliding seat 7 will not deform or shift during the cutting process, thereby ensuring the cutting accuracy of the cutting blade 3.

[0037] More specifically, the rotating assembly also includes two bearings 6, both of which are fitted onto the outer wall of the connecting shaft 4, and the inner ring of the bearing 6 is fixedly installed to the connecting shaft 4. The outer ring of the bearing 6 is engaged in the mounting groove of the support plate 703.

[0038] The base plate 701 serves as the basic support. Two side plates 702 provide support for the bearing 6. Simultaneously, the mounting groove on the support plate 703 provides a mounting position for the bearing 6, allowing the connecting shaft 4 to rotate stably on the sliding seat 7. The bearing 6 reduces friction between the connecting shaft 4 and the sliding seat 7, improving the rotational efficiency and stability of the connecting shaft 4. Furthermore, the outer ring of the bearing 6 is secured within the mounting groove of the support plate 703. This structure ensures the stable installation of the bearing 6 on the sliding seat 7, preventing displacement or loosening of the bearing 6 during the rotation of the connecting shaft 4, thereby guaranteeing the stable rotation of the cutting blade 3 and improving the quality and efficiency of glass cutting. The bearing 6 may include, but is not limited to, sealed bearings.

[0039] More specifically, slots 13 are provided on the side walls of the side plate 702 and the protective cover 2. A spring 14 is fixedly connected to the outer side wall of the protective cover 2. A locking block 5 is fixedly connected to the end of the spring 14 away from the protective cover 2. The locking block 5 is engaged with the side plate 702 and the protective cover 2 respectively through the slots 13.

[0040] The locking block 5 limits the sliding seat 7 through the locking groove 13, and the spring 14 provides elastic force to ensure that the locking block 5 can automatically align with the locking groove 13 and engage.

[0041] Under normal operating conditions, the locking block 5 secures the sliding seat 7 within the protective cover 2 via the locking groove 13, ensuring that the sliding seat 7 does not slide and thus guaranteeing stable cutting by the cutting blade 3. When it is necessary to replace the cutting blade 3, simply pull the locking block 5 to disengage it from the locking groove 13. The sliding seat 7 will then automatically slide downwards under its own weight, exposing the connecting shaft 4, facilitating the replacement of the cutting blade 3. After replacement, by pushing the sliding seat 7 upwards, the locking block 5 will automatically align and engage with the locking groove 13 under the elastic force of the spring 14, re-secureing the sliding seat 7 within the protective cover 2, completing the replacement process of the cutting blade 3. This design of the locking block 5 and spring 14 not only simplifies operation but also ensures the stable fixation and rapid release of the sliding seat 7, greatly improving the replacement efficiency of the cutting blade 3.

[0042] Specifically, the upper end of the protective cover 2 is fixedly connected to a connecting seat 1, and the connecting seat 1 has multiple bolt holes.

[0043] The design of the connecting base 1 allows the glass cutting device of this invention to be easily installed on the equipment that drives its movement, such as the sliding guide rail of a cutting machine or a robotic arm. The fixed connection to external equipment via bolt holes ensures the stability of the device during operation, preventing loosening or displacement due to equipment vibration, thereby guaranteeing the cutting accuracy and stability of the cutting blade 3. Simultaneously, the design of the connecting base 1 also facilitates the installation and disassembly of the device, enabling quick installation and replacement on different equipment.

[0044] In this technical solution, the motor 11 includes, but is not limited to, a servo motor or a stepper motor.

[0045] In use, first install the connecting seat 1 on the device that drives the device to move, then start the motor 11. The motor 11 drives the second gear 9 to rotate, the second gear 9 drives the first gear 8 to rotate, and the first gear 8 drives the connecting shaft 4 to rotate, thereby causing the cutting blade 3 to rotate and realize the function of cutting glass.

[0046] When it is necessary to replace the worn cutting blade 3, pull the locking block 5 to disengage it from the slot 13 on the sliding seat 7. The sliding seat 7 will automatically slide downwards under its own weight, exposing the connecting shaft 4. The maintenance personnel can then directly remove the connecting shaft 4, replace it with a new one, and push the sliding seat 7 upwards. The locking block 5 will automatically align and engage with the slot 13 under the elastic force of the spring 14, thus re-fixing the sliding seat 7 inside the protective cover 2, completing the replacement process of the cutting blade 3.

[0047] At the same time, the worn cutting blade 3 can be removed from the disassembled connecting shaft 4 and replaced with a good cutting blade 3 as a replacement. This combination facilitates the replacement of the cutting blade 3, effectively improving the convenience of replacing the cutting blade 3 and increasing the cutting efficiency.
