Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of edge grinding machine, in particular to a glass edge grinding machine with controllable polishing force. BACKGROUND

[0002] Glass edge grinding machine is one of the earliest and largest used mechanical equipment in glass deep processing equipment, mainly for grinding and making special shapes. Proper use of the edge grinding machine can not only ensure normal production, but also prolong the service life of the machine. It is divided into single-arm special-shaped edge grinding machine, straight-line edge grinding machine and template edge grinding machine. The existing glass edge grinding machine cannot push the glass tightly, and when people use the glass edge grinding machine, it cannot grind the glass of different widths, and cannot adjust the width of different glass conveying, which can easily cause the glass to loosen and deviate, resulting in uneven grinding and affecting the grinding quality.

[0003] Therefore, the patent with publication number "CN219094615U" discloses a single-edge glass edge grinding machine, which mainly comprises a workbench, a first concave seat fixedly connected to the right top of the workbench, a gas cylinder fixedly connected to the left inner cavity of the workbench, a top rod fixedly connected to the right side of the gas cylinder, a moving block fixedly connected to the right side of the top rod, a moving column fixedly connected to the top of the moving block, and a second concave seat fixedly connected to the top of the moving column. When adjusting the conveying position, the gas cylinder drives the top rod to start moving, the top rod drives the moving block to start moving, the moving block drives the sliding sleeve to slide on the sliding rod, and at the same time, the moving block drives the moving column to start moving, the moving column drives the second concave seat to start moving, so that the second concave seat moves to the designated position, and the baffle tightens the glass on the guide wheel at this time.

[0004] However, when the above-mentioned single-edge glass edge grinding machine works, the polishing head and the glass surface are in hard contact when they contact, which can only provide a hard contact method of polishing pressure when polishing, and the polishing pressure between the high-speed rotating polishing head and the glass surface cannot be controlled. Once the two are in contact at high speed, the whole glass will be scrapped, which can easily lead to a decrease in the yield. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a glass edge grinding machine with controllable polishing force, which utilizes a spiral spring to provide the required torque resistance control effect for linkage, and the intermediate medium is a buffer liquid. Once the polishing pressure between the polishing head and the glass surface is greater than the control effect of the spiral spring, the buffer liquid can be discharged outward in time, so that the polishing head can stop polishing the glass in time, thereby preventing the occurrence of glass scrap caused by excessive high-speed polishing pressure, and solving the above-mentioned technical problems.

The bottom of the upper rotating disk and the top of the lower rotating disk are respectively provided with three corresponding upper and lower hemispherical grooves. A ball is placed between each corresponding upper and lower hemispherical groove.

[0010] Preferably, the structural shape of the cross-section of the rod through the hole is consistent with the structural shape of the cross-section of the central linkage shaft, both being polygonal structures, and the structural dimensions of the cross-section of the rod through the hole match the structural dimensions of the cross-section of the central linkage shaft.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 and Figure 2 A glass edging machine with controllable grinding force includes a drive motor 1 with a motor connecting plate 2 mounted on its outer circumference and a grinding head 3 that rotates indirectly with the rotor 4 of the drive motor 1. The motor connecting plate 2 is fixedly connected to the corresponding part of a robotic arm that runs along a predetermined track.

[0028] To achieve the desired buffer solution retention, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3A central liquid injection mechanism 5 needs to be set up, which has a hollow central cylinder 51 that can rotate indirectly with the rotor 4 and is hollow inside, and a liquid injection channel 57 that can fill the central hollow cylinder 51 with buffer solution. First, using the liquid injection device, the buffer solution is filled into the liquid reserved cavity 54 and each sealed space connected to the liquid reserved cavity 54 through the liquid valve 58 until the buffer solution is discharged outward through the No. 5 liquid flow hole 76, and then the liquid injection can be stopped, thereby achieving the reserved effect of buffer solution.

[0029] For details regarding the structure of the central liquid injection mechanism 5, please refer to [link / reference]. Figure 3 The device includes a hollow cylindrical body 51 in the middle. A first connecting plate 52 and a second connecting plate 53 are respectively provided at the bottom and top of the hollow cylindrical body 51. A liquid pre-reserved cavity 54 is provided inside the hollow cylindrical body 51. A first liquid flow hole 55 is provided at the bottom of the hollow cylindrical body 51, connecting the external space and the bottom of the liquid pre-reserved cavity 54. A second liquid flow hole 56 is provided at the top of the hollow cylindrical body 51, connecting the external space and the top of the liquid pre-reserved cavity 54. A liquid injection channel 57 is provided on the circumferential side of the hollow cylindrical body 51, connecting the external space and the liquid pre-reserved cavity 54, and a liquid valve 58 is installed inside. The liquid valve 58 is a valve that can control the outward flow of liquid and allow the buffer solution to be normally injected into the liquid pre-reserved cavity 54.

[0030] To achieve detachable linkage effects, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5A separate, combined linkage mechanism 6 needs to be set up, which includes a bottom hollow cylinder 61 fixedly installed at the bottom of the central hollow cylinder 51 and internally connected to the internal structure of the central hollow cylinder 51; a piston plate 67 placed inside the bottom hollow cylinder 61 and capable of moving downward under the pressure of the buffer solution; an upper rotating disk 69 located inside the bottom hollow cylinder 61 and capable of moving longitudinally with the piston plate 67; a lower rotating disk 611 located directly below the upper rotating disk 69; and three rotating disks arranged in a ring array on the upper rotating disk 69. Between the lower rotating disk 611 and the upper rotating disk 69, there are ball bearings 614 that allow the lower rotating disk 611 to rotate with the upper rotating disk 69. Under normal operation, the central hollow cylinder 51 will drive the bottom hollow cylinder 61 to rotate. Since the cross-sectional shape of the rod through hole 65 is consistent with the cross-sectional shape of the central linkage shaft 68 (both are polygonal structures), and the cross-sectional dimensions of the rod through hole 65 match the cross-sectional dimensions of the central linkage shaft 68, the bottom hollow cylinder 61 will drive the central linkage shaft 68 and the upper rotating disk 69 to rotate. As the rotating disk 69 rotates, the piston plate 67, under the pressure of the buffer solution, creates a mutual squeezing force between the upper rotating disk 69 and the lower rotating disk 611. This force prevents the ball bearing 614 from dislodging from the upper hemispherical groove 612, thereby driving the lower rotating disk 611 to rotate. Finally, this drives the bottom rotating shaft 610 and the grinding head 3 to rotate. The movement of the grinding head 3 is controlled by the robotic arm, thus grinding the glass. Once the frictional resistance between the grinding head 3 and the glass surface during the grinding process exceeds a certain threshold, the grinding pressure will be insufficient. When the elastic strength of the helical spring 78 is reached, the helical spring 78 will be compressed, and the buffer fluid will be discharged outward through the fifth liquid flow hole 76. At this time, the pressure of the liquid on the piston body 67 is insufficient, and the mutual squeezing force between the upper rotating disk 69 and the lower rotating disk 611 will be reduced until the ball 614 disengages from the upper hemispherical groove 612. At this time, the bottom hollow cylinder 61 rotates normally under the action of the drive motor 1, while the lower rotating disk 611 cannot drive the grinding head 3 to continue rotating, thereby achieving a separable linkage effect.

[0031] For the specific structure of the detachable and combined linkage mechanism 6, please refer to [link / reference]. Figure 4 and Figure 5The device includes a hollow bottom cylinder 61. A third connecting plate 62, integrally formed with and fixedly installed at the bottom of a first connecting plate 52, is located at the top of the hollow bottom cylinder 61. A first component movable cavity 63 is located inside the hollow bottom cylinder 61. A third liquid flow hole 64 is located at the top of the first component movable cavity 63, and the top of the third liquid flow hole 64 communicates with the bottom of the first liquid flow hole 55. A rod through hole 65 is located at the center of the bottom of the first component movable cavity 63. The bottom end of the rod through hole 65... A second component movable cavity 615 is provided, and the bottom end of the second component movable cavity 615 is provided with a component mounting hole 66 communicating with the external space. A piston plate 67 capable of moving axially along the first component movable cavity 63 is placed inside the bottom hollow cylinder 61 located within the first component movable cavity 63. A central linkage shaft 68 passing through a rod through a hole 65 is fixedly installed at the bottom end of the piston plate 67. An upper rotating disk 69 is fixedly installed at one end of the central linkage shaft 68 located inside the second component movable cavity 615. The bottom hollow cylinder... A bottom rotating shaft 610, rotatable, is mounted inside the mounting hole 66 of the component via a bearing. The bottom end of the bottom rotating shaft 610 is fixedly connected to the grinding head 3. The top end of the bottom rotating shaft 610 is fixedly mounted inside the movable cavity 615 of the second component. The bottom of the upper rotating disk 69 and the top of the lower rotating disk 611 are respectively provided with three corresponding upper and lower hemispherical grooves 612 and 613. Each corresponding upper hemispherical groove 612 and lower hemispherical groove 613... A ball bearing 614 is placed between the three. The structural radii of the upper hemispherical groove 612 and the lower hemispherical groove 613 are matched with the structural radius of the ball bearing 614. The depth of the upper hemispherical groove 612 and the lower hemispherical groove 613 is less than the structural radius of the ball bearing 614. The lateral distance between the center of the ball bearing 614 and the longitudinal axis of the bottom of the upper rotating disk 69 and the lower rotating disk 611 is greater than the structural radius of the bottom of the upper rotating disk 69 and the lower rotating disk 611, but less than the structural diameter of the bottom of the upper rotating disk 69 and the lower rotating disk 611.

[0032] To control the maximum torque intensity during equipment operation, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 6 and Figure 7A torque resistance control mechanism 7 needs to be set up. This mechanism includes a top hollow cylinder 71 fixedly installed at the top of the central hollow cylinder 51 and internally connected to the internal structure of the central hollow cylinder 51; a contact baffle 77 placed inside the top hollow cylinder 71 to control the outward discharge of the buffer fluid; and a helical spring 78 that provides elastic damping to the movement of the contact baffle 77. Once the frictional resistance between the grinding head 3 and the glass surface during the grinding process, i.e., the grinding pressure, exceeds the elastic strength of the helical spring 78, the ball bearing 614 will cause the upper rotating disk 69 and the lower rotating disk 611 to tend to move away from each other. Due to the bearing connection, the lower rotating disk 611 will not move longitudinally, while the upper rotating disk 69 will tend to move upward, which will cause the helical spring 78 to be compressed. The buffer fluid flows upward through the gap between the fourth liquid flow hole 75 and the plate of the contact baffle 77, and finally discharges outward through the fifth liquid flow hole 76. At this time, the pressure of the liquid on the piston body 67 is insufficient until the ball 614 disengages from the upper hemispherical groove 612. At this time, the bottom hollow cylinder 61 rotates normally under the action of the drive motor 1, while the lower rotating disk 611 cannot drive the grinding head 3 to continue rotating, thus achieving a separable linkage effect.

[0033] For details regarding the specific structure of the torque resistance control mechanism 7, please refer to [link / reference]. Figure 6 and Figure 7 The system includes a top hollow cylinder 71, with a fourth connecting plate 73 fixedly connected to the top of a second connecting plate 53 at its bottom end. A shaft mounting groove 72 for fixing and installing a rotor 4 is located at the center of the top end of the top hollow cylinder 71. A fourth liquid flow hole 75, communicating with a second liquid flow hole 56, is located at the bottom end of the top hollow cylinder 71. A third component movable cavity 74, located at the top of the fourth liquid flow hole 75, is located inside the top hollow cylinder 71. Multiple fifth liquid flow holes 76, communicating with the external space and the third component movable cavity 74, are located at the top end of the top hollow cylinder 71. A device capable of... A contact baffle 77 moves axially along the movable cavity 74 of component number three. The outer circumferential surface of the contact baffle 77 is provided with multiple concave liquid flow channels 79 for liquid flow. A compressed helical spring 78 is fixedly installed on the top of the contact baffle 77. An annular sealing ring 710 is embedded at the bottom end of the contact baffle 77. The bottom surface of the annular sealing ring 710 protrudes downward relative to the bottom surface of the contact baffle 77. The structural radius of the inner ring of the annular sealing ring 710 is larger than the structural radius of the liquid flow hole 75 of component number four. The structural radius of the outer ring of the annular sealing ring 710 is smaller than the distance between the center lines of the liquid flow channels 79 and the contact baffle 77.

[0034] In use, using a liquid injection device, buffer solution is injected into the liquid pre-reserved cavity 54 and each sealed space connected to the liquid pre-reserved cavity 54 through the liquid valve 58 until the buffer solution is discharged outward through the fifth liquid flow hole 76. The injection is then stopped. The central hollow cylinder 51 will drive the bottom hollow cylinder 61 to rotate. Since the cross-sectional shape of the rod through hole 65 is consistent with the cross-sectional shape of the central linkage shaft 68 (both are polygonal structures), and the dimensions of the cross-sectional shape of the rod through hole 65 are consistent with the dimensions of the central linkage shaft 68... With the cross-sectional dimensions of the linkage shaft 68 matched, the bottom hollow cylinder 61 drives the central linkage shaft 68 and the upper rotating disk 69 to rotate. At the same time, under the pressure of the buffer fluid, the piston plate 67 causes the upper rotating disk 69 and the lower rotating disk 611 to have a mutual squeezing force. This force prevents the ball bearing 614 from dislodging from the upper hemispherical groove 612, thereby driving the lower rotating disk 611 to rotate. Finally, it drives the bottom rotating shaft 610 and the grinding head 3 to rotate. The movement of the grinding head 3 is controlled by the robotic arm to grind the glass.
