Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and more specifically to a modular fixing device for glass processing. Background Technology

[0002] Quartz glass is made from high-purity quartz ore through processes such as acid washing, flotation, and melting. It has an extremely low coefficient of linear expansion, about 5% that of ordinary glass, and exhibits excellent high-temperature resistance, corrosion resistance, and thermal shock resistance. Its long-term operating temperature can reach approximately 1200℃, and its instantaneous temperature resistance can reach approximately 1400℃. After the quartz glass inlay is produced, it requires fine processing, during which the glass needs to be fixed in place.

[0003] Currently, commonly used glass fixing devices typically employ mechanical clamping or a single electrostatic adsorption module, combined with a flat rubber film to increase friction. They also use a combination of rubber and bearings for fastening, maintaining a constant fixing pressure value. When fixing smaller workpieces, the energy consumption is basically the same as that for larger workpieces.

[0004] Currently used glass fixing devices, due to pressure fixing, cannot ensure stable fixation when holding irregularly shaped workpieces, often leading to cracking in thin-walled areas and seriously affecting quality stability. At the same time, the existing fixing devices use rubber and bearing assembly fastening methods, which cause rapid bearing wear and rubber aging in the high temperature and humidity environment of quartz glass processing, resulting in high annual equipment maintenance costs. Utility Model Content

[0005] In view of the defects existing in the prior art, the purpose of this utility model is to provide a reinforcement device for quartz glass processing, so as to solve the problem that the glass fixing device in the prior art cannot ensure the stability of fixing when holding irregular workpieces due to pressure fixing, which often leads to cracking of thin-walled areas and seriously affects the quality stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a modular fixing device for glass processing, comprising: A support mechanism, used to hold the glass to be fixed; The pressing mechanism includes: A substrate is spaced apart from the supporting mechanism; multiple telescopic holding components are all located on the side of the substrate close to the supporting mechanism, and are used to adaptively adjust their length according to the surface shape of the glass to be fixed, and cooperate with the supporting mechanism to fix the glass to be fixed. A drive mechanism, which is connected to the base plate, is used to drive the pressing mechanism to move toward the supporting mechanism.

[0007] In some alternative embodiments, the telescopic holding assembly includes: a telescopic assembly, one end of which is connected to the substrate; and a holding block disposed at the other end of the telescopic assembly.

[0008] In some alternative solutions, the pressure block is provided with a rubber pad on the side near the support mechanism.

[0009] In some alternative solutions, the holding block is equipped with an electrostatic generator, the bottom surface of the rubber pad is provided with an electrostatic film, and the electrostatic generator is electrically connected to the electrostatic film.

[0010] In some alternative embodiments, the telescopic holding assembly further includes a pressure sensor for detecting the pressure exerted by the holding block against the glass to be fixed.

[0011] In some alternative solutions, the support mechanism includes: a rotary processing table; A compressed air cushion layer is provided on the rotary processing table for placing the glass to be fixed.

[0012] In some alternative embodiments, the rotary processing table includes: a mounting table; a drive motor, which is vertically disposed within the mounting table and whose rotation axis extends out of the mounting table; and a rotary support table, which is disposed above the mounting table and connected to the rotation axis of the drive motor.

[0013] In some alternative embodiments, the mounting platform includes: a base for mounting the support mechanism; and a support frame connected to the base for mounting the drive mechanism.

[0014] In some alternative configurations, the support frame is vertically positioned outside the base, with a support plate at the upper end of the support frame, and the drive mechanism is mounted on the support plate.

[0015] In some alternative configurations, the plurality of telescopic holding components are arranged in a square matrix.

[0016] Compared with the prior art, the advantages of this utility model are as follows: When using this device to fix irregularly shaped glass, the glass to be fixed is first placed on the support mechanism. The drive mechanism drives the base plate of the pressing mechanism to move towards the support mechanism, which in turn drives the telescopic holding assembly to move towards the support mechanism. After part of the telescopic holding assembly abuts against the surface of the glass to be fixed, the remaining telescopic holding assembly adaptively adjusts its length so that it also abuts against the surface of the glass to be fixed. This makes the fixing of irregularly shaped glass by this device more stable, thus solving the problem that the prior art cannot ensure the fixing stability when processing irregularly shaped glass workpieces.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, in one aspect, the present invention provides a modular fixing device for glass processing, comprising: a supporting mechanism 2, a pressing mechanism 3, and a driving mechanism 4.

[0025] Among them, the supporting mechanism 2 is used to place the glass to be fixed.

[0026] The pressing mechanism 3 includes: a base plate 31, which is spaced apart from the supporting mechanism 2; and a plurality of telescopic pressing components 32, which are all located on the side of the base plate 31 near the supporting mechanism 2, for adaptively adjusting their length according to the surface shape of the glass to be fixed, and cooperating with the supporting mechanism 2 to fix the glass to be fixed.

[0027] The drive mechanism 4, which is connected to the base plate 31, is used to drive the pressing mechanism 3 to move toward the supporting mechanism 2.

[0028] When using this device to fix irregularly shaped glass, the glass to be fixed is first placed on the support mechanism 2. The drive mechanism 4 drives the base plate 31 of the pressing mechanism 3 to move towards the support mechanism 2. During the movement of the base plate 31, the telescopic holding assembly 32 will move towards the support mechanism 2, so that part of the telescopic holding assembly 32 abuts against the surface of the glass to be fixed. This part of the telescopic holding assembly 32 will apply pressure to the corresponding surface of the glass to be fixed. The remaining telescopic holding assembly 32 adaptively adjusts its length through the telescopic assembly 321, so that the remaining telescopic holding assembly 32 also abuts against the surface of the glass to be fixed, so that the device can fix irregularly shaped glass more stably, which solves the problem of not being able to ensure the fixing stability when processing irregularly shaped glass workpieces in the prior art.

[0029] In this embodiment, the supporting mechanism 2 is used to place the glass to be fixed. The types of glass to be fixed include, but are not limited to, irregularly shaped glass workpieces and thin-walled glass workpieces. The pressing mechanism 3 includes a base plate 31 and multiple telescopic pressing components 32 connected to the base plate 31; the base plate 31 can be a square plate or other structural forms that fix multiple telescopic pressing components 32. The driving mechanism 4 uses a proportional valve-controlled cylinder to dynamically adjust the downward pressure, avoiding excessive pressure during the downward movement of the pressing mechanism 3 by the driving mechanism 4, which could cause stress-induced breakage of the glass workpiece to be tested.

[0030] In some alternative embodiments, the support mechanism 2 includes: a rotary processing table 22; and a compressed air cushion layer 21 disposed on the rotary processing table 22 for placing the glass to be fixed.

[0031] In this embodiment, the compressed air cushion layer 21 is disposed on the rotary processing table 22 for placing the glass to be fixed, which is especially suitable for thin-walled glass workpieces and irregularly shaped glass workpieces to avoid local stress cracks.

[0032] In some optional embodiments, the rotary processing table 22 includes: a mounting table 221; a drive motor 223, which is vertically disposed within the mounting table 221 and whose rotation shaft extends out of the mounting table 221; and a rotary support table 222, which is disposed above the mounting table 221 and connected to the rotation shaft of the drive motor 223.

[0033] In this embodiment, the drive motor 223 of the rotary processing table 22 is a direct-drive servo motor; the rotation shaft of the direct-drive servo motor is a ceramic hybrid rotation shaft; and low-viscosity lubricating oil is used to reduce the large frictional resistance caused by the bearing and gear set structure of the traditional motor, which can reduce the power consumption of the direct-drive servo motor by more than 30%. The ceramic hybrid rotation shaft is used to reduce the maintenance requirements under high temperature and high humidity conditions and improve the energy-saving effect of the modular fixing device for glass processing.

[0034] In some optional embodiments, the telescopic pressing assembly 32 includes: a telescopic assembly 321, one end of which is connected to the substrate 31; and a pressing block 322, which is disposed at the other end of the telescopic assembly 321.

[0035] In this embodiment, the telescopic holding assembly 32 includes a telescopic assembly 321, one end of which is connected to the substrate 31, and holding blocks 322 disposed at the other end of the telescopic assembly 321. During the downward movement of the substrate 31, the telescopic holding assembly 32 moves downward as well. Some holding blocks 322 first contact the surface of the irregularly shaped glass workpiece, providing pressure to the workpiece; the remaining holding blocks 322 automatically extend and retract through the telescopic assembly 321 to adjust their positions, ensuring contact with the surface of the irregularly shaped glass workpiece and providing pressure. The telescopic holding assembly 32 is used to fully contact the surface of irregularly shaped glass workpieces with varying heights, improving the fixing effect and reducing edge fixing blind spots. Simultaneously, different holding blocks 322 generate different pressures when facing irregularly shaped glass workpieces, ensuring fixing stability while reducing the risk of breakage of glass workpieces with uneven thickness.

[0036] In some alternative embodiments, the plurality of telescopic holding components 32 are arranged in a square matrix.

[0037] In this embodiment, the multiple telescopic holding components 32 are arranged in a square matrix of n rows and n columns; where n≥2.

[0038] In some alternative embodiments, the holding block 322 is provided with a rubber pad on the side near the supporting mechanism 2.

[0039] In this embodiment, the rubber pad and the pressure block 322 are connected on the side near the support mechanism 2. When the pressure block 322 moves downward, the rubber pad first contacts the surface near the glass to be fixed, which helps to form a buffer between the pressure block 322 and the glass to be fixed, and avoids the pressure block 322 directly contacting the surface near the glass to be fixed, causing the glass to be fixed to break.

[0040] In some alternative embodiments, the telescopic holding assembly 32 further includes a pressure sensor for detecting the pressure of the holding block 322 against the glass to be fixed.

[0041] In this embodiment, the driving mechanism 4 drives the base plate 31 of the pressing mechanism 3 to move toward the supporting mechanism 2, thereby moving the telescopic pressing component 32 toward the supporting mechanism 2. This causes part of the telescopic pressing component 32 to abut against the surface of the glass to be fixed. The pressure sensor detects the pressure of the telescopic pressing component 32 abutting against the surface of the glass to be fixed. When the set pressure is reached, the driving mechanism 4 stops driving. The telescopic component 321 of the remaining telescopic pressing component 32 adaptively adjusts its length so that its corresponding pressing block 322 also abuts against the surface of the glass to be fixed. When the pressure sensor detects that the pressure of the pressing block 322 abutting against the glass to be fixed reaches the set pressure, the telescopic component 321 stops adjusting its length.

[0042] In some optional embodiments, the holding block 322 is provided with an electrostatic generator, and the bottom surface of the rubber pad is provided with an electrostatic film, and the electrostatic generator is electrically connected to the electrostatic film.

[0043] In this embodiment, one end of the rubber pad is connected to an electrostatic generator, and the other end is connected to an electrostatic film. As the holding block 322 moves downwards, the electrostatic film moves towards the surface of the glass to be fixed. If contact occurs, the pressure sensor sends real-time feedback of the contact status to the electrostatic generator, at which point the generator starts. The holding block 322 continuously applies pressure to the surface of the glass to be fixed, and through the cooperation of the electrostatic generator and the electrostatic film, the glass is electrostatically adsorbed and fixed, enhancing the fixing capability of the pressing mechanism 3 and reducing the overall power consumption required for the modular fixing device in glass processing by more than 40%.

[0044] As the holding block 322 moves downward, the electrostatic film moves toward the surface of the glass to be fixed. If the two do not make contact, the pressure sensor will send a real-time feedback of the non-contact status to the electrostatic generator. The holding block 322 will not make contact, and the electrostatic generator will not start. Both the electrostatic generator and the electrostatic film are in the off state, which can avoid the electrostatic generator and the electrostatic film from consuming energy under no-load conditions.

[0045] In some alternative embodiments, the mounting frame 1 includes: a base 11 for mounting the support mechanism 2; and a support frame 12 connected to the base 11 for mounting the drive mechanism 4.

[0046] In this embodiment, the base 11 can be a square base or other fixing components that support and fix the support mechanism 3; the support frame 12 can be a vertically arranged square column or other support components that fix and connect the drive mechanism 4.

[0047] The base 11 is equipped with a heat energy conversion module, which converts the waste heat generated by the drive motor 223 into low-voltage power to supply the electrostatic generator, reducing the energy consumption of the support mechanism 2 by more than 30% and improving the energy efficiency of the modular fixing device for glass processing. At the same time, due to the heat energy recovery and utilization of the drive motor 223, the load on the workshop air conditioning is also reduced to a certain extent, thus reducing the workshop's operating power consumption.

[0048] Mounting frame 1 serves to fix and support the support mechanism 2 and drive mechanism 4, which can improve the fixation stability of the modular fixing device for glass processing during the processing of irregularly shaped glass workpieces.

[0049] In some alternative embodiments, the support frame 12 is arranged vertically and located outside the base 11, with a support plate 13 at the upper end of the support frame 12, and the drive mechanism 4 is mounted on the support plate 13.

[0050] In this embodiment, the support frame 12 can be vertically arranged on the outside of the base 11, or other connection methods that support the base 11 can be adopted; the support plate 13 can be horizontally arranged, with one end connected to the support frame 12 and the other end connected to the drive mechanism 4, or other connection methods that have a fixed action point for the drive mechanism 4 can be adopted.
