Description

Technical Field

[0001] The invention belongs to the field of tempered glass processing, and in particular relates to a tempered glass positioning and sliding cutting device. Background Art

[0002] Tempered glass is a type of safety glass. In fact, tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. Now, the processing of tempered glass requires multiple processes, including cutting and polishing. When cutting tempered glass, professional laser cutters are generally used to accurately cut the tempered glass.

[0003] Chinese utility model patent CN113185104A discloses a positioning and sliding cutting device for ultra-white tempered glass processing and its implementation method, which belongs to the technical field of ultra-white tempered glass processing, and includes an operating table, a fixed bracket is installed on the upper surface of the operating table, a hydraulic cylinder is installed on the fixed bracket, the piston rod of the hydraulic cylinder is connected to a rotating motor, the output shaft of the rotating motor is installed with a sliding cutting blade through a spline, and a sliding positioning mechanism is provided below the sliding cutting blade, and the sliding positioning mechanism is installed on the upper surface of the operating table. The positioning and sliding cutting device for ultra-white tempered glass processing of the present invention and its implementation method can effectively fix the ultra-white tempered glass, so that the ultra-white tempered glass is not easy to deviate during sliding cutting, and the sliding cutting accuracy of the ultra-white tempered glass can be improved, and the positioning pressure plate can position and fix ultra-white tempered glass of different thicknesses;

[0004] The above design can stably position the tempered glass to be cut through the design of multiple groups of components, ensuring the stability and accuracy of the equipment during operation.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] Depend on Figure 1 , Figure 2 and Figure 3As shown, a tempered glass positioning and sliding cutting device includes a processing table 1, a cutting component 2, a lifting mechanism 3 and a supporting mechanism 4. The cutting component 2 is slidably installed on the upper end of the processing table 1, and the lifting mechanism 3 is slidably installed inside the processing table 1. The lifting mechanism 3 includes a supporting plate 31, a protective shell 32, an electric push rod 33 and an adsorption component 34. The protective shell 32 is arranged inside the processing table 1, the electric push rod 33 is fixedly installed inside the protective shell 32, the support plate 31 is fixedly installed at the output end of the protective shell 32, and the supporting mechanism 4 is arranged on the side of the lifting mechanism 3.

[0033] During use, the equipment is installed to the target position, and then the tempered glass to be cut is placed on the upper surface of the lifting mechanism 3 inside the processing table 1. At this time, the central area of ​​the tempered glass needs to be placed on the upper surface of the lifting mechanism 3, and other waste areas need to be placed on the surface of the supporting mechanism 4. After that, through the use of the cutting component 2, the tempered glass on the upper surfaces of the lifting mechanism 3 and the supporting mechanism 4 can be stably cut. After the cutting is completed, the waste of tempered glass will be attached to the upper surface of the supporting mechanism 4, and the material to be used will be attached to the upper surface of the lifting mechanism 3. By starting the electric push rod 33, the output end of the electric push rod 33 pushes the support plate 31 to move. When the material cutting is completed, the support plate 31 moves to the upper end as a whole. At this time, the support plate 31 will push out the cut material. The staff can quickly and safely take and move the pushed out material without touching other tempered glass waste, thereby ensuring the stability of the equipment during operation.

[0034] By the attached Figure 4 As shown, in this embodiment, the support plate 31 includes a top plate 311 and a taking groove 312 . The top plate 311 is fixedly mounted on the output end surface of the protective shell 32 , and the taking grooves 312 are equidistantly provided on the upper surface of the top plate 311 .

[0035] During use, the tempered glass to be cut is placed on the upper surface of the top plate 311, and the finished product area of ​​the tempered glass needs to be aligned with the center of the top plate 311 when placing it, so that the finished tempered glass can be pushed out when the top plate 311 moves upward. The design of the taking groove 312 can assist the staff in taking the finished tempered glass area on the upper surface of the top plate 311.

[0036] By the attached Figure 4 As shown, in this embodiment, the adsorption assembly 34 includes a suction cup 341, an entry tube 342 and a matching groove 343. The suction cup 341 is fixedly installed at the center of the support plate 31, and the entry tube 342 is fixedly installed on the side of the suction cup 341. A matching groove 343 is opened inside the support plate 31 outside the suction cup 341, and the matching groove 343 is slidably connected to the entry tube 342.

[0037] During use, the suction cup 341 is used to adsorb the tempered glass on the upper surface of the support plate 31, so that the tempered glass can be stably attached to the upper surface of the support plate 31. Subsequently, no matter the cutting component 2 is cutting the tempered glass or the lifting mechanism 3 and the supporting mechanism 4 are moving as a whole, the tempered glass will be stably placed on the upper surface of the support plate 31, thereby enhancing the stability of the equipment during operation.

[0038] By the attached Figure 4 As shown, in this embodiment, the adsorption assembly 34 also includes a connecting pipe 344, a negative pressure pump 345 and an output pipe 346. The negative pressure pump 345 is fixedly installed at the bottom end of the processing table 1. The air inlet of the negative pressure pump 345 is fixedly installed with a connecting pipe 344. The end of the connecting pipe 344 is threadedly connected to the end of the matching groove 343. The output pipe 346 is fixedly installed at the air outlet of the negative pressure pump 345.

[0039] During use, by starting and running the negative pressure pump 345, the inlet pipe 342 is connected to the connecting pipe 344 with the cooperation of the connecting pipe 344 and the matching groove 343, and the negative pressure pump 345 extracts gas through the inlet pipe 342 and the connecting pipe 344. When the gas inside the inlet pipe 342 and the connecting pipe 344 is evacuated, a negative pressure area is formed inside the inlet pipe 342 and the connecting pipe 344. The inlet pipe 342 will automatically absorb the air on the upper end of the suction cup 341, so that a negative pressure area is formed inside the suction cup 341. At this time, the suction cup 341 will automatically absorb the tempered glass on the upper end of the support plate 31, and the tempered glass can be stably attached to the upper end of the support plate 31.

[0040] By the attached Figure 5 As shown, in this embodiment, the supporting mechanism 4 includes a side support plate 41, a side connecting plate 42, a positioning groove 43 and a positioning rod 44. The side support plates 41 are symmetrically arranged on both sides of the lifting mechanism 3, the side connecting plates 42 are symmetrically arranged between the side support plates 41, and the positioning rod 44 is symmetrically fixedly installed on the side of the side support plate 41. A positioning groove 43 is opened inside the side connecting plate 42 on the side of the positioning rod 44, and the positioning groove 43 is slidably plugged into the positioning rod 44.

[0041] During use, the corresponding size of the side support plate 41 and the side connecting plate 42 are selected according to the size of the tempered glass to be cut, and then the side support plate 41 and the side connecting plate 42 are spliced, and the positioning rod 44 on the side of the side support plate 41 is aligned with the positioning groove 43 in the side connecting plate 42. When the positioning rod 44 is fully inserted into the positioning groove 43, the side support plate 41 will be stably fitted with the side connecting plate 42, and the splicing of the side support plate 41 and the side connecting plate 42 is quickly completed. After the side support plate 41 and the side connecting plate 42 are spliced, the blank area formed at the middle end is consistent with the overall specifications of the support plate 31. With the cooperation of the support plate 31, the side support plates 41 and the side connecting plates 42, a detachable tempered glass support bottom plate is formed to stably support and position the tempered glass.

[0042] By the attached Figure 6 As shown, in this embodiment, the support mechanism 4 also includes a fixed thread group 45 and a support assembly 46. The fixed thread group 45 is fixedly installed at the top corner after the side connecting plate 42 is connected to the side support plate 41, and the fixed thread group 45 simultaneously penetrates the side connecting plate 42 and the side support plate 41, and the support assembly 46 is fixedly installed at the bottom end of the side connecting plate 42.

[0043] During use, when the side support plate 41 and the side connecting plate 42 are spliced ​​together, the fixing thread group 45 can be inserted into the groove at the connection between the side support plate 41 and the side connecting plate 42, and the nut at the end of the fixing thread group 45 is continuously moved along the screw rod to reduce the distance between the side support plate 41 and the side connecting plate 42, thereby enhancing the stability of the connection between the side support plate 41 and the side connecting plate 42. The use of the support assembly 46 can support and position the side connecting plate 42 to ensure that when the rear support plate 31 moves, the side support plate 41 and the side connecting plate 42 are still stably installed around the lifting mechanism 3, and the waste on the upper surface of the support mechanism 4 will not move with the support plate 31, thereby ensuring the stability of the components during operation.

[0044] By the attached Figure 6 As shown, in this embodiment, the support assembly 46 includes a support seat 461, a support rod 462 and a fixed seat 463. The support seat 461 is fixedly installed on the bottom end of the side connecting plate 42, the support rod 462 is fixedly installed on one side of the bottom end of the support seat 461, and the fixed seat 463 is fixedly installed on the outside of the protective shell 32, and the end of the fixed seat 463 is fixedly connected to the support rod 462.

[0045] During use, the fixing seat 463 is used to install the supporting point of the supporting mechanism 4 components, and the supporting point is set on the outside of the protective shell 32. Then, the side connecting plate 42 is locked and supported by the cooperation of the supporting rod 462 and the fixing seat 463. When the supporting plate 31 moves to the upper end, the side connecting plate 42 will still be installed in the original position and will not move with the supporting plate 31. With the cooperation of the fixing thread group 45, the position of the side support plate 41 can be synchronously locked, thereby ensuring the stability of the internal components of the supporting mechanism 4 during the operation of the equipment.

[0046] By the attached Figure 6 and Figure 7 As shown, in this embodiment, the device also includes a moving mechanism 5, which is used to assist the lifting mechanism 3 and the supporting mechanism 4 to move stably inside the processing table 1. The moving mechanism 5 includes a moving end 51, a screw rod 52, an outer shell 53 and a motor 54. The moving end 51 is fixedly installed on one side of the bottom end of the lifting mechanism 3, the screw rod 52 is rotatably installed inside the processing table 1, the screw rod 52 is threadedly engaged with the moving end 51, the outer shell 53 is fixedly installed on one side of the outside of the processing table 1, the motor 54 is fixedly installed inside the outer shell 53, and the output end of the motor 54 is fixedly connected to the end of the screw rod 52.

[0047] During use, by starting the motor 54, the output end of the motor 54 will drive the screw rod 52 to rotate synchronously, and the movable end 51 will automatically move along the outer wall and extension direction of the screw rod 52 under the drive of the screw rod 52, thereby driving the lifting mechanism 3 and the supporting mechanism 4 to move inside the processing table 1, which is convenient for rapid loading and speeds up the work efficiency during the operation of the equipment.

[0048] By the attached Figure 6 and Figure 7 As shown, in this embodiment, the moving mechanism 5 also includes a guide rod 55, a moving frame 56 and a limit assembly 57. The moving frame 56 is fixedly mounted on the side of the lifting mechanism 3 away from the moving end 51. The guide rod 55 is fixedly mounted inside the processing table 1, and the guide rod 55 is parallel to the screw rod 52. The guide rod 55 is slidably connected to the moving frame 56, and the limit assembly 57 is symmetrically fixedly mounted on both sides of the inner wall of the processing table 1.

[0049] During use, the guide rod 55 is installed so that the guide rod 55 passes through the movable frame 56 and the two ends of the guide rod 55 are fixed to the inner wall of the processing table 1. When the lifting mechanism 3 moves, the movable frame 56 will move synchronously with the lifting mechanism 3. The movable frame 56 will slide stably in accordance with the outside of the screw rod 52 to ensure the stability of the lifting mechanism 3 when moving.

[0050] By the attached Figure 7 As shown, in this embodiment, the limit assembly 57 includes a limit frame 571, a rotating rod 572 and a limit wheel 573. The limit frame 571 is symmetrically fixedly installed on the inner wall of the processing table 1, and the rotating rod 572 is equidistantly installed inside the limit frame 571 for rotation. The limit wheel 573 is fixedly installed outside the rotating rod 572, and the outer surface of the limit wheel 573 is slidably connected to the bottom end of the support mechanism 4.

[0051] During use, by installing the limit frame 571, the support mechanism 4 can fit into the upper surface of the limit frame 571 when moving, thereby achieving a certain limiting effect. Moreover, by using the limit wheel 573, when the support mechanism 4 slides along the upper surface of the limit frame 571, the limit wheel 573 will roll under the drive and friction of the support mechanism 4, thereby assisting the stable movement of the support mechanism 4.

[0052] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
