Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass cutting equipment, specifically relating to a glass cutting device for the production of liquid crystal displays. Background Technology
[0002] Glass panels are a key component in LCD displays. After production, glass panels need to be precisely cut according to the size of the LCD display. Existing glass cutting technologies include laser cutting and mechanical cutting. Mechanical cutting uses a cutting head to cut the glass.
[0003] However, when cutting glass plates with a cutting head, the glass plates need to be placed on the cutting worktable. When the cutting head is cutting, there is no clamping and fixing device on both sides of the glass area during the cutting process. This can easily lead to irregular damage to the cutting seam. It is also impossible to ensure that the pressure of the cutting head on the glass plate is constant during the cutting process. Multiple cuts are required to ensure the cutting quality, making the operation quite cumbersome. Utility Model Content
[0004] This utility model provides a glass cutting device for the production of liquid crystal displays, in order to solve at least one of the above-mentioned technical problems.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A glass cutting device for producing liquid crystal displays includes a fixed base with clamping mechanisms symmetrically arranged on both sides of the fixed base and a cutting assembly located in the middle of the fixed base between the two clamping mechanisms. The cutting assembly includes a groove detachably connected to the fixed base, a main connecting column slidably connected within the groove, the main connecting column having an extension extending beyond the groove, a tool holder fixedly connected to the outer end of the extension, and a spring fixedly connected between the main connecting column and the inner wall of the groove.
[0007] The clamping mechanism presses and fixes the glass on both sides of the cutting line to the worktable surface, maintaining the stability of the glass plate during cutting and applying pressure to the cutting line area to prevent irregular breakage during cutting, which would affect the quality of the finished product. The compression of the main connecting column compresses the spring, thereby creating a stable and sufficient positive pressure between the cutting blade mounted on the blade holder and the glass plate, ensuring the cutting effect of the cutting blade on the glass plate and improving cutting efficiency.
[0008] As an optimization, the lower end of the fixing base is provided with a mounting groove, and a mounting seat is provided in the mounting groove. The groove body is fixed on the mounting seat. The mounting groove and mounting seat enable quick disassembly and installation of the groove body, which is beneficial for the subsequent maintenance, repair and replacement of the groove body, cutter head and cutter holder.
[0009] As an optimization, the clamping mechanism includes a cylinder body, a connecting shaft slidably connected within the cylinder body, and a connecting portion extending beyond the cylinder body. A pressure roller bracket is fixedly connected to the outer end of the connecting portion, and pressure roller components are spaced apart on the pressure roller bracket. A cylinder for venting air into the cylinder body is located at the upper end of the cylinder body, and an exhaust valve is provided on the cylinder body. When it is necessary to increase the pressure of the pressure roller components on the glass sheet, the pressure of the pressure roller components on the glass sheet can be flexibly controlled through the arrangement of the cylinder, cylinder body, connecting shaft, and exhaust valve. The pressure roller components roll on the glass sheet during the cutting process of the cutting blade, which can minimize friction with the glass sheet, protect the smoothness of the glass sheet surface, avoid wear on the glass surface caused by friction, and ensure the quality of the finished glass product.
[0010] As an optimization, a limiting shaft is slidably connected to the fixed base, and the limiting shaft is fixedly connected to the pressure roller bracket; the setting of the limiting shaft can ensure the stability of the pressure roller bracket's posture.
[0011] As an optimization, a linear guide rail is also included. The fixed base is slidably connected to the linear guide rail. Guide grooves are provided at both the upper and lower ends of the linear guide rail. The fixed base has a split upper plate and a lower plate. Guide flanges that are slidably connected to the guide grooves are provided on the upper plate and the lower plate respectively. The linear guide rail can drive the fixed base to slide along a straight line, thereby enabling the cutting blade to perform automatic and precise straight cutting. The guide flanges and guide grooves can further ensure the cutting accuracy of the cutting blade.
[0012] As an optimization, the upper or lower plate is provided with a threaded locking device, which is a threaded knob. After a cutting line is completed, the locking device can lock the fixed seat to the linear guide rail. After the fixed seat is locked, the fixed seat can be moved to the next cutting line by external equipment to prevent the fixed seat from shifting on the linear guide rail.
[0013] As an optimization, the outer wall of the pressure roller is provided with a soft rubber layer; the soft rubber layer can further prevent the pressure roller from generating friction marks on the glass surface.
[0014] As an optimization, symmetrical sliding connection of limiting posts is provided in the groove, and the outer end of the limiting posts is fixedly connected to the tool holder seat; the setting of the limiting posts can prevent the main connecting post from axially deflecting, so as to prevent the cutting blade's cutting direction from forming an angle with the cutting line, which would affect the cutting accuracy.
[0015] As an optimization, the cylinder is equipped with a pressure gauge; the pressure gauge can display the air pressure output by the cylinder, so as to facilitate real-time observation and flexible control of the pressure roller component.
[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0017] This application uses a clamping mechanism to clamp and fix the glass on both sides of the cutting line to the worktable surface, maintaining the stability of the glass plate during cutting and applying pressure to the cutting line area to prevent irregular breakage during cutting and affect the quality of the cut product. The main connecting column and spring settings can ensure a stable and sufficient positive pressure between the cutting blade and the glass plate, thereby ensuring the cutting effect of the cutting blade on the glass plate and improving cutting efficiency.

[0028] Reference Figures 1 to 3 A glass cutting device for LCD screen production includes a fixed base 2, with clamping mechanisms symmetrically arranged on both sides of the fixed base 2, and a cutting assembly located in the middle of the fixed base 2 between the two clamping mechanisms. The cutting assembly includes a groove 8 detachably connected to the fixed base 2, a main connecting column 81 slidably connected inside the groove 8, the main connecting column 81 having an extension extending beyond the groove 8, a tool holder seat 9 fixedly connected to the outer end of the extension, and a spring fixedly connected between the main connecting column 81 and the inner wall of the groove 8.
[0029] Those skilled in the art will understand that the cutting of glass for LCD displays is performed on a cutting worktable. The operator first lays the entire glass panel flat on the worktable, and then performs precise cutting to the specified dimensions using this application. During cutting, the cutting assembly is first placed on the cutting line of the glass, and then two clamping mechanisms are placed on either side of the cutting line to clamp and fix the glass on both sides of the cutting line to the worktable surface. This maintains the stability of the glass panel during cutting and applies pressure to the cutting line area to prevent irregular breakage and ensure the quality of the finished product. During cutting, by controlling the distance between the fixing seat 2 and the glass panel, the extension of the main connecting column 81 is pressed into the groove 8 by the glass panel by 5-10mm, compressing the spring. This creates a stable and sufficient positive pressure between the cutting blade mounted on the blade holder 9 and the glass panel, ensuring the cutting effect of the cutting blade on the glass panel and improving cutting efficiency.
[0030] As a preferred embodiment of this application, refer to Figures 1-2 as well as Figure 4 The lower end of the fixed base 2 is provided with a mounting groove 7, and a mounting seat 71 is provided in the mounting groove 7. The groove body 8 is fixed on the mounting seat 71. The mounting groove 7 and the mounting seat 71 enable quick disassembly and installation of the groove body 8, which is beneficial for the later maintenance, repair and replacement of the groove body 8, the cutter head and the tool holder 9.
[0031] As one specific embodiment of the clamping mechanism in this application, refer to Figures 1-4 The pressing mechanism includes a cylinder body 3, with a connecting shaft 31 slidably connected inside the cylinder body 3. The connecting shaft 31 has a connecting portion extending beyond the cylinder body 3, and a pressure roller bracket 4 is fixedly connected to the outer end of the connecting portion. Pressure roller components 41 are spaced apart on the pressure roller bracket 4. A cylinder 32 for venting air into the cylinder body 3 is provided at the upper end of the cylinder body 3, and an exhaust valve is provided on the cylinder body 3. When it is necessary to increase the pressure of the pressure roller components 41 on the glass plate, air is injected into the cylinder body 3 through the cylinder 32, and the air pressure pushes the connecting shaft 31 to increase the pressure of the pressure roller components 41 on the glass plate. Conversely, the pressure is reduced by venting the air from the cylinder body 3 through the exhaust valve. Furthermore, the pressure roller components 41 roll on the glass plate during the cutting process of the cutting blade, which minimizes friction with the glass plate, protects the smoothness of the glass surface, avoids wear caused by friction, and ensures the quality of the finished glass product. The outer wall of the pressure roller components 41 is provided with a soft rubber layer, which further prevents friction marks from the pressure roller components 41 on the glass surface.
[0032] Preferably, a limiting shaft 5 is slidably connected to the fixed base 2, and the limiting shaft 5 is fixedly connected to the pressure roller bracket 4. The limiting shaft 5 ensures the stability of the pressure roller bracket 4's posture.
[0033] As a preferred embodiment of this application, refer to Figures 1-4 It also includes a linear guide rail 1, a fixed base 2 slidably connected to the linear guide rail 1, and guide grooves at both the upper and lower ends of the linear guide rail 1. The fixed base 2 has a split upper plate and a lower plate, and guide flanges that are slidably connected to the guide grooves are respectively provided on the upper plate and the lower plate. The linear guide rail 1 drives the fixed base 2 to slide along a straight line, thereby enabling the cutting blade to perform automatic and precise linear cutting. The guide flanges and guide grooves further ensure the cutting accuracy of the cutting blade.
[0034] Furthermore, the upper or lower plate is equipped with a threaded locking element 6, which is a threaded knob. After a cutting line is completed, the locking element 6 can lock the fixed seat 2 to the linear guide 1. After the fixed seat 2 is locked, it can be moved to the next cutting line by external equipment to prevent the fixed seat 2 from shifting on the linear guide 1.
[0035] In a preferred embodiment of the cutting assembly, symmetrical sliding limit posts 82 are connected within the groove 8, and the outer ends of the limit posts 82 are fixedly connected to the tool holder 9. The limit posts 82 prevent axial deflection of the main connecting post 81, which would cause an angle between the cutting blade's cutting edge direction and the cutting line, affecting cutting accuracy.
[0036] As a preferred example of the above-described embodiment, the cylinder 32 is equipped with a pressure gauge, which can display the air pressure output by the cylinder 32, so as to facilitate real-time observation and flexible control of the pressure roller component 41.
