Description

Technical Field

[0001] The utility model relates to the technical field of edge grinding equipment, and more specifically, to an edge grinder. Background Art

[0002] Glass is a material with various excellent properties and easy to process. It is an amorphous inorganic material obtained by heating raw materials to melt and then cooling and solidifying. Due to the amorphous structure of glass, its physical and mechanical properties are isotropic. It is widely used in various fields, such as architectural glass, daily-use glass, optical glass, electro-vacuum glass, medicinal glass, etc.

[0003] Edge grinding is an indispensable process in the processing of glass products. Generally, it is located at the end of glass processing. Through edge grinding, the sharp edges of the glass can be made smooth, which not only improves the aesthetics but also reduces the risk of being scratched.

[0004] In the existing glass edge grinders, the adjustment in the Z-axis direction usually relies on a lead screw drive system. However, there are the following defects in using the lead screw drive for fine adjustment in the Z-axis direction:

[0005] In the lead screw drive system, due to the clearance between the lead screw and the nut, and the elastic deformation of the transmission components, there will be a backlash (also known as return error). This means that when changing the movement direction, the lead screw will not immediately start to move in the reverse direction but will first eliminate this clearance, which is likely to cause inaccurate positioning. During the glass edge grinding process, if there is a backlash in the fine adjustment in the Z-axis direction, it may cause the grinding wheel to jump during the adjustment process, thereby affecting the flatness of the glass surface. Summary of the Utility Model

Detailed implementation manners

[0038] The following further describes in detail the implementation manners of the present utility model in conjunction with the drawings and embodiments. The detailed descriptions and drawings of the following embodiments are used to exemplarily illustrate the principles of the present utility model, but cannot be used to limit the scope of the present utility model, that is, the present utility model is not limited to the described embodiments.

[0039] For a better understanding of the present utility model, the present utility model is further described below in conjunction with the drawings and implementation manners:

[0040] See Figure 1 As shown, a grinding machine provided by an embodiment of the present utility model includes a frame 1, a loading and unloading mechanism 3, and an edge grinding mechanism 4.

[0041] In this embodiment, a four-side centering and correction mechanism 2 is arranged on the frame 1. The four-side centering and correction mechanism 2 is used to fix the workpiece, and the workpiece is centered and corrected through the four-side centering and correction mechanism 2 to ensure that the center of the workpiece is accurately aligned with the processing reference line, significantly improving the positioning accuracy of the workpiece before edge grinding.

[0042] See Figure 1 And Figure 2As shown in the figure, the loading and unloading mechanism 3 is arranged on one side of the four-side centering and correcting mechanism 2. The loading and unloading mechanism 3 is used to grab the workpiece and place the workpiece on the four-side centering and correcting mechanism 2. The edge grinding mechanism 4 is arranged on the other side of the four-side centering and correcting mechanism 2. The edge grinding mechanism 4 is used to grind the workpiece located on the four-side centering and correcting mechanism 2.

[0043] See Figures 3 - 5 As shown in the figure, the edge grinding mechanism 4 includes a mounting frame 41, a grinding wheel unit 42 and a Z-axis lifting and adjusting module 43. The Z-axis lifting and adjusting module 43 includes a first driving motor 431 and a rack group 432. The rack group 432 and the grinding wheel unit 42 are both mounted on the mounting frame 41. The extending end of the first driving motor 431 is meshed and connected with the rack group 432. The first driving motor 431 is used to drive the mounting frame 41 to move downward along the Z-axis direction so that the grinding surface of the grinding wheel unit 42 is flush with the side wall of the workpiece. Specifically, the first driving motor 431 drives the rack group 432 to realize the lifting adjustment of the grinding wheel unit 42 in the Z-axis direction. The meshing and transmission mode between the rack and the gear 24 has high transmission accuracy and stability. Since the rack group 432 is mounted on the mounting frame 41 and moves together with the grinding wheel unit 42, the stability of the grinding wheel during the adjustment process is ensured, the jumping phenomenon is reduced, and thus the surface flatness of the workpiece after grinding is improved.

[0044] See Figure 4 As shown in the figure, the edge grinding mechanism 4 includes a fixing plate 44 and two first guiding mechanisms 45 mounted on the fixing plate 44. The two first guiding mechanisms 45 both include a first linear guide rail arranged along the Z-axis direction and a first sliding block arranged on the first linear guide rail. The first sliding block is connected with the mounting frame 41. By installing the two first guiding mechanisms 45 and arranging the first linear guide rail along the Z-axis direction, stable guidance is provided for the mounting frame 41, effectively reducing the deviation of the mounting frame 41 caused by vibration or external force, thereby ensuring the stability during the edge grinding process.

[0045] See Figure 6As shown, the edge grinding mechanism 4 also includes an X-axis moving adjustment module 46, which includes a second drive motor 461, a ball screw 462, and a slider body 463 installed on the ball screw 462. The second drive motor 461 is connected to the ball screw 462 through a coupling, and the fixed plate 44 is installed on the slider body 463. The second drive motor 461 drives the ball screw 462 to rotate to drive the slider body 463 to perform linear motion along the X-axis direction. Specifically, when processing a large workpiece plate or a special-shaped workpiece (square), its side may need to be polished to different degrees at different positions due to process requirements. Through the X-axis moving adjustment module 46, the operator can easily adjust the position of the grinding wheel so that it is accurately aligned with the area to be processed, thereby achieving comprehensive and flexible grinding of the entire workpiece plate side, which not only improves the processing efficiency, but also reduces the downtime caused by replacing the workpiece or adjusting the mechanism.

[0046] See also Figure 3 As shown, in order to play a buffering role, abutment sheets 48 for abutting against the buffer member 49 are provided on both sides of the fixed plate 44. When the fixed plate 44 moves to the left along the X-axis direction along with the slider body 463, the abutment sheet 48 on the left side thereof will move accordingly and contact the buffer member 49 on the left side. Due to the movement of the fixed plate 44, the abutment sheet 48 will exert a force on the buffer member 49. After the buffer member 49 is subjected to the force exerted by the abutment sheet 48, the buffer member 49 begins to shrink. This shrinkage is the deformation of the buffer member 49 in order to absorb and disperse the impact force. Through shrinkage, the buffer member 49 can convert the impact force that may have directly acted on the mechanical structure into its own deformation energy, thereby playing a role in protecting the mechanical structure.

[0047] See also Figure 6 As shown, the edge grinding machine provided by the embodiment of the utility model further includes two guide modules 47, the two guide modules 47 are respectively located on both sides of the X-axis moving adjustment module 46, the guide module 47 includes a second linear guide rail 471 arranged along the X-axis direction and a second sliding block 472 arranged on the second linear guide rail 471, and the fixed plate 44 is connected to the second sliding block 472. In this embodiment, the two guide modules 47 are respectively located on both sides of the X-axis moving adjustment module 46, which helps to enhance the stability of the entire edge grinding machine when it moves in the X-axis direction. The second linear guide rail 471, as a guide element, provides a reliable guide for the second sliding block 472 (and then for the fixed plate 44 and the edge grinding mechanism 4 thereon), effectively preventing the deviation and shaking caused by lateral force or vibration, and ensuring the smooth progress of the processing process.

[0048] In the workpiece processing industry, the traditional manual loading and unloading method is not only inefficient, but also prone to errors and damage due to human factors.

[0049] Based on this, the present utility model provides a loading and unloading mechanism 3 for an edging machine. Refer to Figures 7 - 8 As shown, the loading and unloading mechanism 3 includes a mounting base 31, a linear module 32, and a grasping component 33. The linear module 32 is installed on the mounting base 31, and the grasping component 33 is installed on the linear module 32. The linear module 32 can drive the grasping component 33 to move up and down in the Z-axis direction. The grasping component 33 includes a third driving motor 331 and a rotating arm 332. Suction cup assemblies 333 are provided at both ends of the rotating arm 332. One suction cup assembly 333 is used to grasp the workpiece to be edged, and the other suction cup assembly 333 is used to grasp the edged workpiece. The third driving motor 331 can drive the rotating arm 332 to rotate 180° so that the workpiece to be edged located below one suction cup assembly 333 and the edged workpiece located below the other suction cup assembly 333 complete the position swapping.

[0050] By adopting this loading and unloading mechanism 3, the fully automated transfer of the workpiece to be edged from the conveying mechanism to the processing station and the edged workpiece from the processing station to the conveying mechanism can be synchronously achieved. This not only reduces the labor cost but also improves the production efficiency.

[0051] Refer to Figure 1 and Figure 2 As shown, the edging machine further includes a centrifugal fan and a noise reduction module 5. The centrifugal fan is connected to the grinding wheel unit 42 through a pipeline. The noise reduction module 5 includes a shielding cover 51 and sound insulation cotton 52. The shielding cover 51 covers the centrifugal fan, the sound insulation cotton 52 is connected to the centrifugal fan, and the hollow cavity of the sound insulation cotton 52 is communicated with the inner cavity of the centrifugal fan.

[0052] In this embodiment, in order to ensure that the grinding wheel unit 42 can move in the X-axis direction, the pipeline connecting the centrifugal fan and the grinding wheel unit 42 has a fixed section and a telescopic section. When the grinding wheel unit 42 moves in the X-axis direction, the telescopic section of the pipeline contracts or elongates accordingly.

[0053] Refer to Figures 9 - 10 As shown, a four-side automatic centering and correction mechanism provided by an embodiment of the present utility model includes a hollow rotating table 21, an air supply device 22, and a correction component 23.

[0054] In this embodiment, the hollow rotary table 21 includes a main body portion 211 and a support table 212 provided on the main body portion 211. A plurality of evenly arranged vacuum adsorption holes 2121 are provided in the support table 212. The ventilation device 22 is communicated with the vacuum adsorption holes 2121 in the support table 212. With this design, the contact area between the workpiece and the support surface is increased, thereby dispersing the stress points and reducing the risk of single-point concentrated stress. At the same time, the evenly arranged plurality of vacuum adsorption holes 2121 can make the adsorption force distribution uniform. Compared with the uneven adsorption force caused by manually adjusting the position of the suction cup, this design significantly improves the stability and consistency of the adsorption effect. It not only avoids the vibration or deformation of the workpiece during edge grinding due to uneven adsorption force, but also improves the edge grinding accuracy and the edge grinding quality of the workpiece. At the same time, it also reduces the frequent shutdowns and safety hazards caused by adsorption failure during the processing.

[0055] It is worth mentioning that in the traditional method, the suction cups are often arranged along the edge of the workpiece, resulting in the middle of the workpiece being suspended. The workpiece is prone to being squeezed in the middle during processing due to the edge force, resulting in cracking. A four-sided automatic centering and correction mechanism provided by the present utility model provides effective support and protection for the middle of the workpiece through the increased contact area and the evenly distributed vacuum adsorption holes 2121, reduces the risk of cracking in the middle of the workpiece during processing, and improves the product yield and quality stability. In addition, it also reduces the downtime and cost losses caused by workpiece cracking.

[0056] In this embodiment, the correction assembly 23 is provided on the outer periphery of the support table 212, and the correction assembly 23 is used to perform centering and correction on the workpiece. With this design, the correction assembly 23 directly performs centering and correction on the workpiece placed on the support table 212 to ensure that the center of the workpiece is accurately aligned with the processing reference line, significantly improving the positioning accuracy of the workpiece before edge grinding and reducing the positioning deviation caused by manual operation or equipment error.

[0057] See Figure 11 As shown, a sealed cavity 2122 is provided in the support table 212. The sealed cavity 2122 is located between the vacuum adsorption holes 2121 and the ventilation device 22, and the ventilation device 22 and the vacuum adsorption holes 2121 are connected through the sealed cavity 2122. Specifically, under the action of a vacuum pump or other air extraction equipment, the ventilation device 22 quickly extracts air from the vacuum adsorption holes 2121 through the sealed cavity 2122, thereby forming a stable negative pressure environment between the support table 212 and the workpiece.

[0058] In this embodiment, the design of the sealed cavity 2122 helps to reduce the noise generated by the air extraction equipment such as the vacuum pump during operation; since the air is effectively guided and extracted in the sealed cavity 2122, the turbulence and eddy current phenomena of the air flow in the pipeline are reduced, thereby reducing the generation of noise.

[0059] See also Figure 11 As shown, a through hole 2123 is provided in the support platform 212, and the through hole 2123 is used to connect the closed cavity 2122 and the vacuum adsorption hole 2121, and the through hole 2123 and the vacuum adsorption hole 2121 are coaxially arranged. This design ensures the smoothness and consistency of the airflow during the flow process, so that the negative pressure generated by the ventilation device 22 can be directly and efficiently transmitted to each vacuum adsorption hole 2121 through the closed cavity 2122. Secondly, due to the alignment and connection between the through hole 2123 and the vacuum adsorption hole 2121, the negative pressure can be evenly distributed at various positions of the support platform 212, avoiding the problem of uneven force on the workpiece caused by uneven adsorption force; improving the stability of the workpiece, and reducing the risk of rupture in the middle of the workpiece due to concentrated force, which is particularly important for processing large and thin workpieces, and can effectively ensure product quality and production safety.

[0060] See also Figure 12 and Figure 13 As shown, the correction component 23 includes four swing mechanisms 231 and a driving mechanism 232. The four swing mechanisms 231 are connected end to end in sequence. One of the four swing mechanisms 231 is provided with a gear 24 for cooperating with the driving mechanism 232. The driving mechanism 232 includes a driving cylinder 2321 and a gear condition 2322 connected to the driving cylinder 2321. The gear condition 2322 and the gear 24 are meshingly connected.

[0061] Specifically, when the driving cylinder 2321 is working, the driving cylinder 2321 pushes the gear condition 2322 to perform linear motion. The movement of the gear condition 2322 is transmitted to the gear 24 through the meshing relationship, causing the gear 24 to rotate. Since the gear 24 is connected to one of the swinging mechanisms 231, the swinging mechanism 231 swings accordingly. Since the four swinging mechanisms 231 are connected end to end in sequence, the movement of one swinging mechanism 231 will drive the other swinging mechanisms 231 to perform coordinated motion through the connection between the mechanisms, thereby realizing multi-directional correction of the entire correction component 23.

[0062] See also Figure 13 As shown, the swing mechanism 231 includes a mounting bracket 2311, a rotating rod 2312 and a limit piece 2313. The gear 24 is mounted on the rotating rod 2312, and the rotating rod 2312 is movably mounted on the mounting bracket 2311. The limit piece 2313 is connected to the rotating rod 2312. When the rotating rod 2312 rotates, the limit piece 2313 swings toward the direction close to the workpiece to abut against the side wall of the workpiece.

[0063] Specifically, adjacent two swing mechanisms 231 are connected by a transmission group 25. The transmission group 25 includes a first transmission block 251 and a second transmission block 252. The first transmission block 251 is installed on the rotating rod 2312 of a swing mechanism 231, and the second transmission block 252 is installed on the rotating rod 2312 of another swing mechanism 231. A first conical inclined surface is provided on one side of the first transmission block 251, and a second conical inclined surface is provided on one side of the second transmission block 252. The first conical inclined surface and the second conical inclined surface are in contact. In this embodiment, the first conical inclined surface and the second conical inclined surface are in contact. When one of the rotating rods 2312 rotates, the power can be transmitted to the other rotating rod 2312 through the friction of the inclined surface.

[0064] Preferably, in another embodiment, a first thread is provided on the first conical inclined surface. Correspondingly, a second thread meshing with the first thread is provided on the second conical inclined surface. The power is transmitted through the thread meshing, thereby improving the transmission stability.

[0065] See Figures 13 - 14 As shown, the four-side automatic centering and correcting mechanism further includes a first guiding component 26 and a base 27. The first guiding component 26 includes a first guide rail 261 and a first slider 262 arranged on the first guide rail 261. The first guide rail 261 is arranged in parallel with the tooth condition 2322, and the tooth condition 2322 is fixedly connected with the first slider 262. The mounting bracket 2311 is arranged on the base 27, and a second guiding component 28 is arranged on the side wall of the base 27. The second guiding component 28 includes a second guide rail 281 and a second slider 282 arranged on the second guide rail 281. The second guide rail 281 is arranged in parallel with the first guide rail 261, and the extending end of the driving cylinder 2321 is connected with the second slider 282 through a connecting piece 29. With such a design, the smooth movement of the tooth condition 2322 can be improved. It should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this application is usually placed, or the orientation or positional relationship commonly understood by those skilled in the art, or the orientation or positional relationship when the product of this application is usually placed. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to this application.

[0066] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
