Description

Technical Field

[0001] This utility model belongs to the field of display glass and relates to an anti-chipping edge auxiliary clamping mechanism for cutting display glass. Background Technology

[0002] Display glass is a special glass material that combines optical properties and display technology. It is mainly used on the surface of the screen or core components of various display devices. It has high light transmittance, which can ensure that the displayed content is clearly visible. At the same time, it also has a certain degree of hardness and wear resistance, which can protect the internal display structure from scratches and damage.

[0003] In the production of display glass, it needs to be cut to meet the requirements of use. During the cutting process, an auxiliary clamping mechanism is required to prevent the display glass from moving or chipping and breaking.

[0004] CN217351191U discloses a glass fiber cutting device with a clamping mechanism. By adjusting the threaded fit of the bolts and support frame, as well as the limiting effect of the limiting component on the limiting frame and the lifting plate, the lifting plate and the limiting frame can be raised and lowered, thereby driving the slide rod and the rotating frame to rise and fall, adjusting the distance between the pressure roller and the worktable. At the same time, the clamping component can press the pressure roller onto the surface of the glass fiber. The distance between multiple pressure rollers can be adjusted to adapt to the clamping of glass of different lengths. Compared with the above-mentioned prior art, this solution is easier to adjust the clamping force of the clamping mechanism.

[0005] The aforementioned glass fiber cutting device with a clamping mechanism has the following drawbacks: With increased use, the springs become fatigued due to prolonged stress, gradually losing elasticity, and may even deform or break, resulting in insufficient or unstable clamping force. This prevents the glass from adhering tightly to the surface, increasing the risk of displacement or chipping during cutting. Furthermore, it cannot guarantee uniform force distribution during use. If the clamping force is uneven, the pressure on different parts of the glass will vary, causing stress to concentrate in areas of lower pressure during cutting. This not only causes the cutting trajectory to deviate from the preset path, resulting in dimensional inaccuracies, but may also lead to cracks and chipping due to excessive localized stress, severely impacting the cutting quality and yield of display glass. Summary of the Invention

[0006] The technical problem this invention aims to solve is that, with increased use, springs become fatigued due to prolonged stress, their elasticity gradually diminishes, and they may even deform or break, resulting in insufficient or unstable clamping force. This prevents them from tightly adhering to the glass surface, increasing the risk of displacement or chipping during cutting. Furthermore, uneven force distribution cannot be guaranteed during use. Uneven clamping forces cause differences in pressure across different parts of the glass, leading to stress concentration in areas of lower pressure during cutting. This not only causes the cutting trajectory to deviate from the preset path, resulting in dimensional inaccuracies, but may also cause cracks in the glass due to excessive localized stress. Defects such as edge chipping severely affect the cutting quality and yield of display glass. This paper provides an anti-chipping auxiliary clamping mechanism for display glass cutting, comprising a stable base, a placement platform welded to the upper surface of the stable base, fixed seats welded to the four corners of the upper surface of the placement platform, two push plates mounted on the upper surface of the placement platform, and an adjustment unit provided on the outer surface of the fixed seats for driving the two push plates to slide and adjust on the upper surface of the placement platform. The outer surfaces of the two push plates are each provided with a monitoring unit for detecting whether the force is uniform when assisting in clamping the display glass.

[0007] The monitoring unit includes an angle rod, one end of which is provided with a plate. Threaded slide rods are slidably installed on the outer surfaces of both ends of the plate. Circular plates are welded to one end of each of the two threaded slide rods. Rubber pads are glued to one side of each of the two circular plates. Pressure sensors for detecting the pressure of the rubber pads on the display glass are embedded inside the two rubber pads. A display module for displaying the pressure monitoring data of the pressure sensors is provided at the other end of the angle rod.

[0008] In this invention, three electric push rods are installed on the upper surface of the two symmetrical push plates. The working ends of the three electric push rods are fixedly installed with the three corner rods respectively. Three positioning rods are fixedly installed on the upper surface of the push plates. The three electric push rods drive the three corner rods to slide and connect with the outer surface of the three positioning rods respectively.

[0009] The outer surface of the other end of the threaded slide rod of this utility model is threaded with a torsion bolt, and a disc spring is sleeved on the outer surface of the threaded slide rod, with one end abutting against the lower surface of the plate and the other end abutting against the upper surface of the disc, in a stretched state.

[0010] The adjustment unit of this utility model includes a double-threaded rod 1, which is rotatably mounted on the surfaces of two fixed seats. A rotating disk is fixedly mounted on one end, and a pulley 1 is fixedly mounted on the other end. A second double-threaded rod is rotatably mounted on the surfaces of the other two fixed seats, and a pulley 2 is fixedly mounted on one end.

[0011] The second pulley of this utility model is connected to the first pulley by a belt. The two push plates are respectively threaded onto the two threaded ends of the first and second double-threaded rods. The first and second double-threaded rods drive the two push plates to slide on the upper surface of the placement platform.

[0012] Two limiting plates are installed on the outer surfaces of both the double-ended threaded rod one and the double-ended threaded rod two described in this utility model.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: when the rubber pad in the monitoring unit is in close contact with the surface of the display glass, the pressure sensor installed on the lower surface of the rubber pad can detect the pressure of the rubber pad on the display glass. The pressure value will be displayed in the display module in real time. By rotating the torsion bolt installed on the threaded slide rod to adjust the disc spring, the pressure of the rubber pad is kept consistent. This avoids defects such as cracks and chipping caused by uneven pressing force before cutting, thus improving the cutting quality and yield of the display glass.

[0014] By replacing traditional springs with disc springs, significant metal fatigue caused by long-term stress is avoided, thus increasing the service life.

[0015] The rotating disc in the adjustment unit drives the double-headed threaded rod to rotate, which in turn drives the two push plates to slide relative to each other via pulley one, belt and pulley two. This allows the movement distance to be adjusted according to the size of the display glass, thus facilitating the auxiliary pressing of the display glass. Attached Figure Description

[0022] like Figures 1 to 5 As shown, an anti-chipping edge-assisted clamping mechanism for cutting display glass includes a stable base 1, a placement platform 2 welded to the upper surface of the stable base 1, fixed seats 3 welded to the four corners of the upper surface of the placement platform 2, two push plates 4 installed on the upper surface of the placement platform 2, an adjustment unit 5 for driving the two push plates 4 to slide and adjust on the upper surface of the placement platform 2 on the outer surface of the fixed seats 3, and a monitoring unit 6 for detecting whether the force is uniform when assisting in clamping the display glass.

[0023] The monitoring unit 6 includes an angle rod 602. One end of the angle rod 602 is provided with a plate 605. Threaded slide rods 606 are slidably installed on the outer surfaces of both ends of the plate 605. Circular plates 609 are welded to one end of the two threaded slide rods 606. Rubber pads 610 are glued to one side of the two circular plates 609. Pressure sensors 611 for detecting the pressure of the rubber pads 610 on the display glass are embedded inside the two rubber pads 610. The other end of the angle rod 602 is provided with a display module 604 for displaying the pressure detection data of the pressure sensors 611.

[0024] In Example 1, the pressure sensor 611 is a piezoresistive pressure sensor. Half of the outer surface of the threaded slide rod 606 is threaded. The rubber pad 610 presses down on the display glass to prevent damage to the surface of the display glass. The display module 604 displays the pressure value in real time when the pressure sensor 611 is working.

[0025] like Figure 3 As shown, three electric push rods 601 are installed on the upper surface of the two symmetrical push plates 4. The working ends of the three electric push rods 601 are fixedly installed with the three corner rods 602 respectively. Three positioning rods 603 are fixedly installed on the upper surface of the push plate 4. The three electric push rods 601 drive the three corner rods 602 to slide and connect on the outer surface of the three positioning rods 603 respectively.

[0026] Example 2: There are six electric push rods 601. The six electric push rods 601 move synchronously, thereby driving the six corner rods 602 to work synchronously. The positioning rod 603 can ensure the stability of the corner rods 602 during operation.

[0027] like Figure 4 As shown, a torsion bolt 607 is threadedly installed on the outer surface of the other end of the threaded slide bar 606, and a disc spring 608 is sleeved on the outer surface of the threaded slide bar 606. One end of the disc spring 608 abuts against the lower surface of the plate 605, and the other end abuts against the upper surface of the disc 609, and is in a stretched state.

[0028] In Example 3, the elastic coefficient of the disc spring 608 can be adjusted by rotating the torsion bolt 607 in conjunction with the threaded slide rod 606. Compared with the threaded spring, the disc spring 608 can delay metal fatigue and increase the service life.

[0029] like Figure 2 As shown, the adjustment unit 5 includes a double-threaded rod 501, which is rotatably mounted on the surfaces of two fixed seats 3. A rotating disk 503 is fixedly mounted on one end, and a pulley 502 is fixedly mounted on the other end. A double-threaded rod 504 is rotatably mounted on the surfaces of the other two fixed seats 3, and a pulley 505 is fixedly mounted on one end.

[0030] In Example 4, both ends of the double-threaded rod 501 and the double-threaded rod 504 are threaded. The two push plates 4 are connected to the double-threaded rod 501 and the double-threaded rod 504 with forward and reverse threads, respectively, so that the two push plates 4 can move relative to each other. A sliding column is installed on the surface of the rotating disk 503. The sliding column is engaged in a groove opened on the outer surface of one of the fixed seats 3, which can fix the double-threaded rod 501.

[0031] like Figure 2 As shown, pulley 2 505 is connected to pulley 1 502 via belt 506. Two push plates 4 are respectively threaded onto the two threaded ends of double-threaded rod 1 501 and double-threaded rod 2 504. Double-threaded rod 1 501 and double-threaded rod 2 504 drive the two push plates 4 to slide on the upper surface of the placement platform 2.

[0032] In Example 5, the surfaces of pulley 502 and pulley 505 have grooves, while the surface of belt 506 has burrs, which can prevent slippage during rotation.

[0033] like Figure 2 As shown, two limiting pieces 507 are installed on the outer surfaces of both the double-ended threaded rod 501 and the double-ended threaded rod 504.

[0034] In Example 6, the two limiting pieces 507 limit the sliding of the two push plates 4.

[0035] Working process or working principle: Adjustment and adaptation. First, the display glass is placed on the upper surface of the placement platform 2. The rotating disk 503 is rotated manually, which drives the double-threaded rod 501 to rotate. The rotation of the double-threaded rod 501 drives the pulley 502 to rotate. The pulley 502 drives the pulley 505 to rotate through the belt 506, which in turn drives the double-threaded rod 504 to rotate. The rotation of the double-threaded rod 501 and the double-threaded rod 504 can drive the push plate 4, which is threaded on the two threaded ends of the double-threaded rod 501 and the pulley 502 respectively, to slide relative to each other on the upper surface of the placement platform 2, thereby adapting to the size of the display glass and initially positioning and clamping the display glass.

[0036] With auxiliary clamping, after the above adjustments are completed, the six electric push rods 601 can be activated to drive the six corner rods 602 downwards, so that the six rubber pads 610 are tightly attached to the surface of the display glass. At the same time, the pressure sensor 611 installed on the lower surface of the rubber pads 610 can detect the pressure of the rubber pads 610 on the display glass. The pressure value will be displayed in the display module 604. When the pressure displayed in the six display modules 604 is different, the elasticity of the disc spring 608 can be adjusted by rotating the torsion bolt 607 threaded on the threaded slide rod 606 to ensure that the pressure of the six rubber pads 610 is consistent. This can ensure uniform force and avoid defects such as cracks and chipping of the glass, thus avoiding serious impact on the cutting quality and yield of the display glass.

[0037] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
