Description

Technical Field

[0001] The present invention relates to the technical field of glass chemical polishing, in particular to a glass chemical polishing device. Background Art

[0002] Chemical polishing of glass uses a polishing liquid containing an acidic solution such as hydrofluoric acid to react with the glass surface, whose main component is silicon dioxide, to generate silicon fluoride, thereby thinning the glass and making the glass surface smoother. In the existing technology, the glass is generally clamped in a glass insert rack, and then the glass insert rack is immersed in the polishing liquid for a chemical reaction. Since the edge of the glass will contact the glass insert rack, it cannot fully contact the polishing liquid, which easily causes undesirable phenomena such as blackening and indentation at the edge of the glass, seriously affecting the quality of the glass. Summary of the Invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a glass chemical polishing device.

[0004] Glass chemical polishing equipment includes: a polishing liquid tank, a glass insert rack, a lifting frame, a transmission mechanism, a servo motor, and a controller. The glass insert rack includes a rack that can vertically clamp the glass. The glass insert rack is placed on the lifting frame that is not immersed in the polishing liquid for loading. The top of the lifting frame is connected to the servo motor through the transmission mechanism. The servo motor is electrically connected to the signal output end of the controller. The lifting frame can drive the glass insert rack to float up and down in the polishing liquid, and the glass on the glass insert rack will slide relative to the rack during the up and down floating.

[0005] Preferably, the transmission mechanism includes a screw rod, a screw rod base, and a nut. The middle bottom surface of the screw rod base is connected to the top of the lifting frame. The bottom end of the screw rod is fixedly connected to the middle of the top surface of the screw rod base. The screw rod vertically penetrates the nut upward and is engaged with the nut thread. When the servo motor drives the nut to rotate, the nut will drive the screw rod to move up and down.

[0006] Preferably, the transmission mechanism further includes a conveyor belt, and the nut and the output shaft of the servo motor rotate synchronously via the conveyor belt.

[0007] Preferably, the transmission mechanism further comprises two groups of vertical guide rods symmetrically arranged about the screw axis, a plurality of through holes matching the diameter of the guide rods are opened on the edge of the screw base, and the screw base is sleeved on the guide rods through the through holes.

[0008] Preferably, the rack includes a row of upper racks and a row of lower racks arranged horizontally, each lower rack is located between every two adjacent upper racks, and the tooth groove opening angles of the upper racks and the lower racks are both between 100° and 120°.

[0009] Preferably, the lifting frame is a plate body with a U-shaped cross section, and a plurality of long holes are opened on the bottom and both sides of the U-shaped plate body.

[0010] Preferably, the device further comprises a control panel, on which a start button, a stop button, a return to loading position button, and a servo reset button electrically connected to the signal input terminal of the controller are provided.

[0011] Further preferably, the control panel further includes a touch screen for setting the movement parameters of the lifting frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Since the glass will slide relative to the rack on the glass insert rack, the edge of the glass will be out of contact with the rack, so that the edge of the glass will be in more complete contact with the polishing liquid, resulting in a more complete chemical reaction. In addition, in the process of floating up and down in the polishing liquid, the polishing liquid will also promptly wash away the reaction products on the edge of the glass and the large surface of the glass, thereby reducing the occurrence of black, indentation and other undesirable phenomena on the edge of the glass, and also achieving a better polishing effect on the entire glass.

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 、 Figure 2, glass chemical polishing equipment, including: a polishing liquid tank 1, a glass insert rack 2, a lifting rack 3, a transmission mechanism, a servo motor 4, and a controller. The glass insert rack 2 includes a rack that can vertically clamp the glass 9. The glass insert rack 2 is placed on the lifting rack 3 that is not immersed in the polishing liquid for loading. The top of the lifting rack 3 is connected to the servo motor 4 through a transmission mechanism. The servo motor 4 is electrically connected to the signal output end of the controller. The lifting rack 3 can drive the glass insert rack 2 to float up and down in the polishing liquid, and the glass 9 on the glass insert rack 2 will slide relative to the rack during the up and down floating. In actual application, a PLC controller can be used, and a program or instruction for controlling the forward and reverse rotation, rotation angle and speed of the servo motor 4 can be pre-input into the controller to accurately control the rising and falling distance and moving speed of the lifting rack 3.

[0022] Since the glass 9 slides relative to the rack on the glass insert rack 2, the edge of the glass 9 is ensured to be out of contact with the rack, so that the edge of the glass 9 is more fully in contact with the polishing liquid, resulting in a more complete chemical reaction. In addition, in the process of floating up and down in the polishing liquid, the polishing liquid will also promptly wash away the reaction products on the edge of the glass and the large surface of the glass, thereby reducing the occurrence of black, indentation and other undesirable phenomena on the edge of the glass, and also achieving a better polishing effect on the glass as a whole.

[0023] Reference Figure 1 、 Figure 3 、 Figure 4 The transmission mechanism includes a screw rod 5, a screw rod base 6, and a nut 7. The middle bottom surface of the screw rod base 6 is connected to the top of the lifting frame 3. The bottom end of the screw rod 5 is fixedly connected to the middle of the top surface of the screw rod base 6. The screw rod 5 vertically penetrates the nut 7 and is threadedly engaged with the nut 7. When the servo motor 4 drives the nut 7 to rotate, the nut 7 will drive the screw rod 5 to move up and down. The screw rod 5 can reliably and powerfully drive the lifting frame 3 to move up and down.

[0024] Reference Figure 2 The transmission mechanism also includes a conveyor belt 11, and the nut 7 and the output shaft of the servo motor 4 rotate synchronously through the conveyor belt 11. In this embodiment, a bearing 12 is installed on a fixed plate 13 fixed to the top of the frame 14, and the bottom of the nut 7 is assembled in the inner ring of the bearing 12, so that the nut 7 is rotatably connected to the fixed plate 13. In actual application, the conveyor belt 11 can adopt a synchronous toothed belt, and a first synchronous wheel compatible with the synchronous toothed belt can be mounted on the top outer periphery of the nut 7, and a second synchronous wheel compatible with the synchronous toothed belt can be mounted on the output shaft of the servo motor 4 to achieve more reliable and smooth transmission. In addition, the above-mentioned belt drive transmission method can also withstand greater impact loads compared with gear transmission, and has lower manufacturing, installation and maintenance costs.

[0025] Reference Figure 1 、 Figure 3 、 Figure 4 The transmission mechanism also includes two groups of vertical guide rods 8 symmetrically arranged about the axis of the screw rod 5. A plurality of through holes 61 that are adapted to the diameter of the guide rod 8 are opened on the edge of the screw rod base 6. The screw rod base 6 is sleeved on the guide rod 8 through the through holes 61 to make the up and down movement of the screw rod 5 more stable. In actual application, the end of the guide rod 8 can be fixed on the frame 14, and a linear bearing that is adapted to the diameter of the guide rod 8 and is mounted on the guide rod 8 is fixedly connected to the frame 14 to further ensure the stability of the up and down movement of the screw rod 5.

[0026] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 The rack includes a row of upper racks 21 and a row of lower racks 22 arranged horizontally up and down, and the rack includes a row of upper racks 21 and a row of lower racks 22 arranged horizontally up and down, each lower rack 22 is located between every two adjacent upper racks 21, with reference to Figure 6 The tooth groove opening angle d of the upper rack 21 and the lower rack 22 is between 100° and 120°. Part of the two long sides of the glass 9 is clamped in the tooth grooves of the two adjacent upper racks 21, and part of the short side of the bottom of the glass 9 is clamped in the tooth groove of the lower rack 22, so that the glass 9 can be conveniently and reliably clamped in the glass insertion rack 2, and the glass 9 can have a certain relative sliding space in the rack.

[0027] Reference Figure 1 、 Figure 3 、 Figure 4 The lifting frame 3 is a plate with a U-shaped cross section. A plurality of long holes 31 are provided on the bottom and both sides of the U-shaped plate. On the one hand, the long holes 31 can allow the polishing liquid to enter the glass insert rack 2 more fully and quickly. On the other hand, it can also reduce the weight of the lifting frame 3, thereby reducing the load on the screw rod 5 and the transmission mechanism.

[0028] Reference Figure 5 The device also includes a control panel 10, on which a start button 101, a stop button 102, a return to loading position button 103, and a servo reset button 104 are provided, which are electrically connected to the controller signal input terminal to facilitate the control of the up and down movement and reset setting of the screw rod 5.

[0029] Reference Figure 5 The control panel 10 also includes a touch screen 105 for setting the movement parameters of the lifting frame 3, so that the operator can set the loading position height and the up and down movement speed of the lifting frame 3, that is, the brushing speed, through the touch screen 105.
