Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, and more specifically, to a four-side automatic centering and correcting mechanism. 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 properties and mechanical properties are isotropic. It is widely used in various fields, such as architectural glass, daily-use glass, optical glass, electro-vacuum glass, pharmaceutical glass, etc.

[0003] In order to meet the needs of reprocessing the cut original sheet glass, especially for secondary processing such as tempering, laminating, and insulating, almost all glass needs to be edge-ground before it officially becomes a product or undergoes secondary processing. Depending on the application field, edge-grinding can be divided into two methods: manual and mechanical. Manual edge-grinding refers to the grinding operation of glass by manually holding an edge-grinding device or tool, and also includes the grinding operation of manually holding the glass through an edge-grinding device. Mechanical edge-grinding refers to the grinding operation achieved when the glass enters the edge-grinding device through a transmission device.

[0004] During the edge-grinding process, in order to ensure that the grinding tool can evenly and accurately grind the glass edge, some fixing mechanisms or positioning mechanisms are required to fix the position of the glass. Currently, the commonly used positioning devices basically install several suction cups at the bottom of the glass to be edge-ground, and then suck the suction cups tightly to fix the glass. And the suction cups are often arranged along the glass edge to prevent the glass edge from being suspended, which may cause the glass to shake during edge-grinding, affecting the edge-grinding accuracy and quality. However, in this type of positioning method, the specific placement position of the suction cups often depends on human experience. After the glass is placed on the suction cups, the position of the suction cups often needs to be adjusted repeatedly to make the suction cups better correspond to the glass, which easily leads to inaccurate glass positioning. When the edge-grinding equipment is started, it is easy to cause excessive grinding of a certain corner of the glass. Secondly, the arrangement of the suction cups adjusted solely by humans is relatively messy, the adsorption force distribution is messy, and the adsorption effect is poor. And in the arrangement method along the glass edge, there is a large amount of suspension in the middle of the glass, and there is no support in the middle. When the edge of the glass is stressed during edge-grinding processing, this force will squeeze the middle of the glass, easily damaging the glass and affecting the glass quality. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a four-side automatic centering and correcting mechanism to solve the problem of low positioning accuracy of glass before edge-grinding.

[0006] The technical solution of the utility model is as follows: A four-side automatic centering and correcting mechanism includes:

[0007] A hollow rotary table, which includes a main body part and a support table provided on the main body part. A plurality of evenly arranged vacuum adsorption holes are provided in the support table;

[0008] An air venting device, which is connected to the vacuum adsorption holes in the support table;

[0009] A calibration component, which is provided on the outer periphery of the support table and is used for centering and calibrating the glass.

[0010] Further, a sealed cavity is provided in the support table. The sealed cavity is located between the vacuum adsorption holes and the air venting device, and the air venting device and the vacuum adsorption holes are connected through the sealed cavity.

[0011] Further, a through hole is provided in the support table. The through hole is used to connect the sealed cavity and the vacuum adsorption holes, and the through hole and the vacuum adsorption holes are coaxially arranged.

[0012] Further, the calibration component includes four swing mechanisms and a driving mechanism. The four swing mechanisms are connected end to end in sequence. One of the four swing mechanisms is provided with a gear for cooperating with the driving mechanism. The driving mechanism includes a driving cylinder and a rack group connected to the driving cylinder, and the rack group is meshed and connected with the gear.

[0013] Further, the swing mechanism includes a mounting bracket, a rotating rod and a limiting member. The gear is mounted on the rotating rod, and the rotating rod is movably mounted on the mounting bracket. The limiting member is connected to the rotating rod. When the rotating rod rotates, the limiting member swings towards the direction close to the glass to abut against the side wall of the glass.

[0014] Further, adjacent two swing mechanisms are connected through a transmission group. The transmission group includes a first transmission block and a second transmission block. The first transmission block is mounted on the rotating rod of one swing mechanism, and the second transmission block is mounted on the rotating rod of another swing mechanism. A first conical inclined surface is provided on one side of the first transmission block, and a second conical inclined surface is provided on one side of the second transmission block. The first conical inclined surface and the second conical inclined surface are in contact with each other.

[0015] Further, it further includes a first guiding module. The first guiding module includes a first guide rail and a first slider provided on the first guide rail. The first guide rail and the rack group are arranged in parallel, and the rack group is fixedly connected to the first slider.

[0016] Furthermore, it further includes a base, the mounting bracket is arranged on the base, a second guiding module is arranged on the side wall of the base, the second guiding module includes a second guide rail and a second slider arranged on the second guide rail, the second guide rail is arranged parallel to the first guide rail, and the extending end of the driving cylinder is connected to the second slider through a connecting piece.

[0017] For the utility model according to the above solution, its beneficial effects are as follows:

[0018] (1) A four-side automatic centering and correction mechanism provided by the utility model includes a hollow rotating table and a ventilation device. The hollow rotating table includes a main body part and a support table arranged on the main body part. A plurality of uniformly arranged vacuum adsorption holes are arranged in the support table; the ventilation device is communicated with the vacuum adsorption holes in the support table; with such a design, the contact area between the glass 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 plurality of uniformly arranged vacuum adsorption holes can make the adsorption force distributed evenly. Compared with the uneven adsorption force brought by manually adjusting the position of the suction cup, this design significantly improves the stability and consistency of the adsorption effect, not only avoids the vibration or deformation of the glass during edge grinding due to uneven adsorption force, but also improves the edge grinding accuracy and the quality of the glass edge grinding. At the same time, it also reduces the frequent shutdowns and potential safety hazards caused by adsorption failure during the processing.

[0019] (2) In the traditional method, the suction cups are often arranged along the edge of the glass, resulting in the middle of the glass being suspended. The glass is prone to being squeezed in the middle due to the edge stress during the processing, resulting in cracking. A four-side automatic centering and correction mechanism provided by the utility model provides effective support and protection for the middle of the glass through the increased contact area and uniformly distributed vacuum adsorption holes, reduces the risk of cracking in the middle of the glass during the processing, and improves the product yield and quality stability. In addition, it also reduces the downtime and cost losses caused by glass cracking.

[0020] (3) A four-side automatic centering and correction mechanism provided by the utility model further includes a correction component, and the correction component is arranged on the outer periphery of the support table, and the correction component is used for centering and correcting the glass. With such a design, the correction component directly performs centering and correction on the glass placed on the support table to ensure that the center of the glass is accurately aligned with the processing reference line, significantly improving the positioning accuracy of the glass before edge grinding and reducing the positioning deviation caused by manual operation or equipment error.

Specific embodiments

[0029] The following will further describe in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The detailed description and drawings of the following embodiments are used to exemplarily illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0030] To better understand the present invention, the following will further describe the present invention in conjunction with the drawings and embodiments:

[0031] See Figures 1 to 2 As shown, a four-side automatic centering and calibration mechanism provided by an embodiment of the present utility model includes a hollow rotating table 1, a ventilation device 2, and a calibration component 3.

[0032] In this embodiment, the hollow rotating table 1 includes a main body portion 11 and a support table 12 provided on the main body portion 11. A plurality of uniformly arranged vacuum adsorption holes 121 are provided in the support table 12; the ventilation device 2 is communicated with the vacuum adsorption holes 121 in the support table 12. With this design, the contact area between the glass 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 uniformly arranged plurality of vacuum adsorption holes 121 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, not only avoiding vibration or deformation of the glass during edge grinding due to uneven adsorption force, but also improving the edge grinding accuracy and the quality of the glass edge grinding. At the same time, it also reduces the frequent shutdowns and potential safety hazards caused by adsorption failure during the processing.

[0033] It is worth mentioning that in the traditional method, the suction cups are often arranged along the edge of the glass, resulting in the middle of the glass being suspended. The glass is prone to being squeezed in the middle during the processing due to the edge stress, resulting in cracking. A four-side automatic centering and calibration mechanism provided by the present utility model provides effective support and protection for the middle of the glass through the increased contact area and the uniformly distributed vacuum adsorption holes 121, reducing the risk of cracking in the middle of the glass during the processing, improving the product yield and quality stability. In addition, it also reduces the downtime and cost losses caused by glass cracking.

[0034] In this embodiment, the calibration component 3 is arranged on the outer periphery of the support table 12, and the calibration component 3 is used to perform centering and calibration on the glass. With this design, the calibration component 3 directly performs centering and calibration on the glass placed on the support table 12, ensuring that the center of the glass is accurately aligned with the processing reference line, significantly improving the positioning accuracy of the glass before edge grinding, and reducing the positioning deviation caused by manual operation or equipment error.

[0035] See Figure 3 As shown, a sealed cavity 122 is provided in the support table 12. The sealed cavity 122 is located between the vacuum adsorption holes 121 and the ventilation device 2, and the ventilation device 2 and the vacuum adsorption holes 121 are connected through the sealed cavity 122. Specifically, under the action of a vacuum pump or other air extraction equipment, the ventilation device 2 quickly extracts air from the vacuum adsorption holes 121 through the sealed cavity 122, thereby forming a stable negative pressure environment between the support table 12 and the glass.

[0036] In this embodiment, the design of the enclosed cavity 122 helps to reduce the noise generated by vacuum pumps and other exhaust equipment during operation; since the air is effectively guided and extracted in the enclosed cavity 122, the turbulence and eddy currents of the airflow in the pipeline are reduced, thereby reducing the generation of noise.

[0037] See also Figure 3 As shown, a through hole 123 is provided in the support platform 12, and the through hole 123 is used to connect the closed cavity 122 and the vacuum adsorption hole 121, and the through hole 123 and the vacuum adsorption hole 121 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 2 can be directly and efficiently transmitted to each vacuum adsorption hole 121 through the closed cavity 122. Secondly, due to the alignment and connection between the through hole 123 and the vacuum adsorption hole 121, the negative pressure can be evenly distributed at various positions of the support platform 12, avoiding the problem of uneven force on the glass caused by uneven adsorption force; improving the stability of the glass, and reducing the risk of the middle part of the glass breaking due to concentrated force, which is particularly important for processing large and thin glass, and can effectively guarantee product quality and production safety.

[0038] See also Figure 4 and Figure 5 As shown, the correction component 3 includes four swing mechanisms 31 and a driving mechanism 32. The four swing mechanisms 31 are connected end to end in sequence. One of the four swing mechanisms 31 is provided with a gear 4 for cooperating with the driving mechanism 32. The driving mechanism 32 includes a driving cylinder 321 and a rack set 322 connected to the driving cylinder 321. The rack set 322 is meshedly connected with the gear 4.

[0039] Specifically, when the driving cylinder 321 is working, the driving cylinder 321 pushes the rack group 322 to perform linear motion. The movement of the rack group 322 is transmitted to the gear 4 through the meshing relationship, causing the gear 4 to rotate. Since the gear 4 is connected to one of the swing mechanisms 31, the swing mechanism 31 swings accordingly. Since the four swing mechanisms 31 are connected end to end in sequence, the movement of one swing mechanism 31 will drive the other swing mechanisms 31 to perform coordinated motion through the connection between the mechanisms, thereby realizing multi-directional correction of the entire correction component 3.

[0040] See also Figure 5 As shown, the swing mechanism 31 includes a mounting bracket 311, a rotating rod 312 and a limit piece 313. The gear 4 is mounted on the rotating rod 312, and the rotating rod 312 is movably mounted on the mounting bracket 311. The limit piece 313 is connected to the rotating rod 312. When the rotating rod 312 rotates, the limit piece 313 swings toward the direction close to the glass to abut against the side wall of the glass.

[0041] Specifically, two adjacent swing mechanisms 31 are connected by a transmission group 5. The transmission group 5 includes a first transmission block 51 and a second transmission block 52. The first transmission block 51 is installed on the rotating rod 312 of one swing mechanism 31, and the second transmission block 52 is installed on the rotating rod 312 of another swing mechanism 31. A first conical inclined surface is provided on one side of the first transmission block 51, and a second conical inclined surface is provided on one side of the second transmission block 52. 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 312 rotates, the power can be transmitted to the other rotating rod 312 through the frictional action of the inclined surface.

[0042] 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.

[0043] See Figures 5 to 6 As shown, the four-side automatic centering and correcting mechanism further includes a first guiding module 6 and a base 7. The first guiding module 6 includes a first guide rail 61 and a first slider 62 arranged on the first guide rail 61. The first guide rail 61 is arranged in parallel with the rack group 322, and the rack group 322 is fixedly connected with the first slider 62. The mounting bracket 311 is arranged on the base 7, and a second guiding module 8 is arranged on the side wall of the base 7. The second guiding module 8 includes a second guide rail 81 and a second slider 82 arranged on the second guide rail 81. The second guide rail 81 is arranged in parallel with the first guide rail 61. The extending end of the driving cylinder 321 is connected with the second slider 82 through a connecting piece 9. With such a design, the smooth movement of the rack group 322 can be improved.
