Description

Technical Field

[0001] This utility model relates to the field of glass cutting technology, and in particular to a glass cutting auxiliary positioning mechanism. Background Technology

[0002] With the rapid development of modern architecture, new energy vehicles and other industries, the requirements for the shape complexity, cutting precision and edge quality of glass have increased significantly. Traditional mass production is gradually shifting to flexible manufacturing, which requires auxiliary positioning technology to quickly switch between different cutting patterns. Glass is brittle and fragile, and manual operation is prone to edge chipping or personnel scratches due to uneven force. Therefore, it is necessary to design glass cutting auxiliary positioning mechanism.

[0003] To this end, patent CN221192007U discloses a positioning mechanism for a glass cutting machine, including a support column, a worktable fixedly connected to the top of the support column, a dust collection box at the bottom of the worktable, a guide rail mounted on the outer side of the worktable, a clamping assembly mounted on one side of the top of the worktable, a mounting plate slidably connected to one side of the guide rail, a stepper motor mounted on one side of the mounting plate, and a receiver mounted on the top of the stepper motor. Through the cooperation of a high-precision positioning sensor and a receiver, when cutting glass, the high-precision positioning sensor measures the position to determine the precise location of the target, the receiver receives the position signal and converts it into a usable form, driving the stepper motor to move the mounting plate on the guide rail, thus moving the cutting assembly to the designated cutting position. This ensures the accuracy and precision of the cutting line, achieving fine cutting of the glass through precise positioning, resulting in a smooth and even cutting edge, reducing cutting errors and waste, and quickly and accurately positioning the glass cutting position.

[0004] While the positioning mechanism of the glass cutting machine mentioned above can make the cutting edge flat and smooth and reduce cutting errors, it is inconvenient to flexibly clamp the glass when clamping and fixing it, and it is easy to damage the glass surface during clamping and fixing. Therefore, it is necessary to design an auxiliary positioning mechanism for glass cutting. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a glass cutting auxiliary positioning mechanism, including a base;

[0007] A limiting rod is fixed to one side of the top of the base, and a glass body is provided on one side of the limiting rod at the top of the base;

[0008] Positioning structures are provided on both sides above the glass body. The positioning structures include support plates evenly arranged on both sides above the glass body. A horizontal plate is fixed to the top of each support plate. An electric push rod is fixed to one side of the bottom of each horizontal plate. A connecting sleeve is provided below the electric push rod. A connecting shaft is slidably connected to the inner wall of the top of each connecting sleeve. A spring is fixed to the bottom end of each connecting shaft. A suction cup is fixed to the outer wall of the bottom of each connecting sleeve.

[0009] Furthermore, a limiting structure is provided on the side of the base away from the limiting rod at the top, a top frame is fixed to the top of the base, a movable structure is fixed to the inner wall of the top of the top frame, and a cutting machine is fixed to the bottom of the movable structure.

[0010] Furthermore, the limiting structure includes a limiting groove, a movable block, a lead screw, a first servo motor, and a positioning plate. The limiting groove is located on the top of the base away from the limiting rod. Movable blocks are provided inside the limiting groove. Lead screws are threaded into the interior of each movable block. A positioning plate is fixed to the top of each movable block. The first servo motor is fixedly installed on the outer wall of one side of the base.

[0011] Furthermore, one end of the lead screw extends into the interior of the base and is rotatably connected to the base, while the other end of the lead screw extends into the exterior of the base and is fixedly connected to the output end of the first servo motor.

[0012] Furthermore, the top end of the positioning plate and the bottom end of the support plate are fixedly connected, and a silicone pad is fixed on one side of the positioning plate near the glass body.

[0013] Furthermore, the movable structure includes mounting plates uniformly fixed to the inner wall of the top of the top frame, with movable blocks provided between adjacent mounting plates. A central shaft is threaded into the internal part of each movable block, and a mounting base is fixed to the bottom of each movable block. A sliding block is provided inside the mounting base, and a rotating shaft is threaded into the internal part of the sliding block. The movable structure also includes a second servo motor fixedly mounted on the outer wall of one end of the mounting base, and an electric telescopic rod is fixed to the bottom of the sliding block. The movable structure also includes a third servo motor fixedly mounted on the outer wall of one side of the mounting plate.

[0014] Furthermore, one end of the central shaft extends to the outside of the mounting plate and is fixedly connected to the output end of the third servo motor, and one end of the rotating shaft extends to the outside of the mounting base and is fixedly connected to the output end of the second servo motor.

[0015] Furthermore, the connecting shaft forms a telescopic structure through springs, the suction cups are symmetrically distributed on both sides of the glass body, and ventilation holes are provided on both sides inside the suction cups.

[0018] The glass cutting auxiliary positioning mechanism provided by this utility model has the following advantages:

[0019] With its positioning structure, the suction cup's negative pressure and the silicone protective pad prevent scratches on the glass body's surface during fixation. The spring's cushioning provides a buffer stroke when the suction cup contacts the glass body, preventing instantaneous impact. The ventilation holes on both sides of the suction cup allow for rapid release / adsorption of the glass body, improving fixation efficiency. This device enables flexible clamping of the glass body, enhancing the convenience and applicability of the glass cutting auxiliary positioning mechanism.

[0020] By incorporating a movable structure, the cutting machine can be moved along the X and Y axes by the lateral movement of the movable block and the longitudinal movement of the sliding block. Combined with the up-and-down lifting of the electric telescopic rod, movement along the Z axis can be achieved, enabling complex curve cutting. This device facilitates the free movement of the cutting machine, improving the convenience and efficiency of the glass cutting auxiliary positioning mechanism during use.

[0021] By setting a limiting structure, the sliding fit between the limiting groove and the movable block can adapt to glass of different thicknesses and sizes without the need to change the clamps. The silicone pad on the inside of the positioning plate disperses the pressure when clamping, which can prevent stress concentration at the glass edge from causing cracks. This enables the device to have the function of facilitating the positioning of the glass body and improves the convenience of using the glass cutting auxiliary positioning mechanism.

[0030] Please see Figures 1-6 The glass cutting auxiliary positioning mechanism provided by this utility model includes a base 1.

[0031] Reference Figures 1-6 A limiting rod 7 is fixed to one side of the top of the base 1. A glass body 8 is provided on one side of the limiting rod 7 at the top of the base 1.

A horizontal plate 61 is fixed to the top of each support plate 62. An electric push rod 63 is fixed to one side of the bottom of each horizontal plate 61. A connecting sleeve 66 is provided below the electric push rod 63. A connecting shaft 64 is slidably connected to the inner wall of the top of the connecting sleeve 66. A spring 67 is fixed to the bottom of each connecting shaft 64. A suction cup 65 is fixed to the outer wall of the bottom of the connecting sleeve 66.

[0032] When the external power supply is connected and the electric push rod 63 is started, the electric push rod 63 will drive the bottom end of the suction cup 65 to contact the top surface of the glass body 8 through the connecting shaft 64 and the connecting sleeve 66 as it descends.
