Description

Technical Field

[0001] The invention belongs to the technical field of glass processing, and in particular relates to a self-fixing glass cutting device. Background Art

[0002] As a multifunctional material, glass is widely used in many fields, including construction, home furnishing, automotive industry, electronic equipment, etc. In order to meet different usage occasions or different design requirements, glass will be bent (or curved glass will be produced), and in order to make the curved glass meet the design requirements, the curved glass will be cut. The existing methods for cutting curved glass include mechanical cutting, laser cutting and water jet cutting.

[0003] When cutting bent glass, due to the high purchase cost of water jet cutting equipment and laser cutting equipment and the high subsequent maintenance and operation costs, some small and medium-sized enterprises and individual workshops usually use mechanical cutting methods. In the process of processing complex curved surfaces or high curvature curved glass, it cannot be guaranteed that the cutting knife and the cut surface of the glass are always at the same angle, which will cause the hot-bent glass to be subjected to different extrusion forces during the cutting process. This will cause the size of the bent glass after cutting to deviate, thereby affecting the assembly accuracy of the finished product. At the same time, the hot-bent glass accumulates internal stress during the molding process. Mechanical cutting will cause these stresses to be suddenly released under the action of different external forces, resulting in microcracks on the surface or edge of the glass, affecting the normal use of the hot-bent glass.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Example 1: A self-fixing glass cutting device, compared with Figure 1-Figure 6 As shown, it includes: a workbench 1, the workbench 1 is equipped with a driving motor 2, the output shaft of the driving motor 2 is fixedly connected to a support rod 3, the support rod 3 is fixedly connected to a multi-stage telescopic rod 5, the telescopic end of the multi-stage telescopic rod 5 is fixedly connected to a fixing member 6; a limit block 7, rotatably connected to the fixing member 6, two convex columns are arranged on the side of the limit block 7 away from the fixing member 6, and the fixing member 6 is fixedly connected to a fixing frame 8; a mounting sleeve 9, fixedly connected to the limit block 7 and located in the fixing frame 8, and the limit block 7 passes through the fixing frame 8; a glass cutter 10, arranged on the mounting sleeve 9; a clamping member 11, having two, both installed on the workbench 1, for clamping and fixing the glass; a detection component, arranged on the workbench 1, for detecting the degree of bending of the glass; a buffer roller 701 is rotatably connected to the convex column of the limit block 7.

[0056] In the above scheme, it is intended to solve the problem that in the process of cutting hot-bent glass using the existing mechanical cutting method, the extrusion force applied to the hot-bent glass is different, which leads to the problem that the hot-bent glass cannot be used normally; the first push rod 4 has an active force, such as an electric push rod; the two protrusions on the limit block 7 are used to limit the swing angle of the limit block 7, so that the connection line between the two protrusions on the limit block 7 always intersects with the cutting position of the glass, and then the glass cutter 10 is always perpendicular to the cutting surface of the glass, thereby ensuring the uniformity of the force applied to the glass; the glass cutter 10 is an existing glass cutting knife; a slide rail is provided on the upper side of the workbench 1, and an electric slider is installed on the clamping member 11, and the clamping member 11 slides in the slide rail of the workbench 1 through the electric slider thereon, so as to clamp and fix hot-bent glasses of different sizes, ensure the stability of the hot-bent glass during the cutting process, and avoid changes in the force due to the deflection of the hot-bent glass.

[0057] Comparison Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the detection component includes: a positioning plate 21, which is slidably connected to the workbench 1, and the positioning plate 21 is slidably connected with uniformly distributed positioning pins 2101; a telescopic sleeve 22, which is rotatably connected to the positioning plate 21, and a tension spring is arranged in the telescopic sleeve 22, and the telescopic part of the telescopic sleeve 22 is fixedly connected with a positioning member 23, and the positioning pin 2101 is used to limit the positioning member 23; a connecting rod 24, which is detachably connected to the telescopic part of the telescopic sleeve 22 and fixedly connected to the fixing member 6; the size of the positioning member 23 is larger than the spacing between two adjacent positioning pins 2101.

[0058] In the above scheme, a method for detecting the bending degree of glass is proposed, so that the device can be applied to hot-bent glass of different sizes, thereby increasing the applicability of the device; Figure 7 The number and distribution of the positioning pins 2101 shown are for illustration only, and the specific number and distribution can be modified according to actual conditions (the smaller the distance between two adjacent positioning pins 2101, the higher the detection accuracy). The positioning member 23 in this embodiment is an arc-shaped bent plate (which can be a round rod or a square); the size of the positioning member 23 is larger than the distance between two adjacent positioning pins 2101, thereby ensuring that the moving trajectory of the positioning member 23 will not be offset during the sliding of the positioning member 23 along the positioning plate 21.

[0059] Working principle: When using this device to cut bent glass, the operator first controls the two clamps 11 to separate, moves the positioning plate 21 out of the workbench 1, disconnects the connecting rod 24 from the telescopic sleeve 22, and then places the glass to be cut on the workbench 1, controls the two clamps 11 to move towards each other and fit with the glass, so that the two clamps 11 clamp the glass, and the operator inserts the positioning plate 21 into the workbench 1, and connects the connecting rod 24 to the telescopic sleeve 22.

[0060] When the positioning plate 21 is inserted into the workbench 1, the operator pulls the telescopic end of the telescopic sleeve 22 to store force in the tension spring therein, and the glass squeezes the positioning pin 2101 in contact with it. The squeezed positioning pin 2101 slides along the positioning plate 21, and the protrusion formed by the squeezed part of the positioning pin 2101 is consistent with the edge of the glass. Then, the telescopic end of the telescopic sleeve 22 is released, and the telescopic end of the telescopic sleeve 22 drives the positioning piece 23 to move under the action of the tension spring thereon, and makes the positioning piece 23 contact with the protruding positioning pin 2101.

[0061] During the movement of the telescopic end of the telescopic sleeve 22, the connecting rod 24 is driven to move synchronously, the connecting rod 24 drives the fixing part 6 to move, the fixing part 6 drives the limit block 7 and the fixing frame 8 to move, the fixing frame 8 drives the installation sleeve 9 and the glass cutter 10 to move, until the positioning part 23 contacts the protruding positioning pin 2101, the two buffer rollers 701 contact the glass and the glass cutter 10 contacts the glass synchronously, during the movement of the fixing part 6, the fixing part 6 drives the telescopic end of the multi-stage telescopic rod 5 to move, thereby extending the multi-stage telescopic rod 5, and the preparation work for cutting the glass is completed at this time.

[0062] After the preparation work is completed, the operator turns on the driving motor 2, and the telescopic end of the driving motor 2 drives the supporting rod 3 to rotate. The supporting rod 3 drives the limiting block 7 and the glass cutter 10 to rotate circumferentially through the multi-stage telescopic rod 5 and the fixing member 6. The fixing member 6 drives the positioning member 23 to rotate through the connecting rod 24 and the telescopic sleeve 22. The positioning member 23 is always fitted with the protruding positioning pin 2101 under the action of the tension spring in the telescopic sleeve 22, so that the limiting block 7 and the glass cutter 10 are both fitted with the outer side of the glass, and the glass cutter 10 rotates along the outer side of the glass to ensure that the distance between the glass cutter 10 and the glass does not change, and thus the squeezing force applied by the glass cutter 10 to the glass will not change, thereby reducing the situation where the glass is broken due to insufficient squeezing force. During the rotation of the glass cutter 10, the glass is cut.

[0063] In the process of the limit block 7 driving the two buffer rollers 701 thereon to rotate, the two buffer rollers 701 are always in contact with the outer side surface of the glass. When the curvature of the outer side surface of the glass changes, the two buffer rollers 701 drive the limit block 7 to deflect, and the line between the two buffer rollers 701 always intersects with the outer side surface of the glass. The limit block 7 drives the installation sleeve 9 to rotate synchronously, and the installation sleeve 9 drives the glass cutter 10 to rotate synchronously. The glass cutter 10 is always perpendicular to the glass, further ensuring that the squeezing force applied by the glass cutter 10 to the glass is always consistent, avoiding the situation where the glass cutter 10 applies different forces to the glass due to changes in the curvature of the glass, thereby causing the glass to break.

[0064] As the support rod 3 rotates, the glass cutter 10 gradually cuts the glass until the support rod 3 rotates 180°, and the drive motor 2 stops working. At this time, the glass cutting work is completed, and the operator disconnects the connecting rod 24 from the telescopic sleeve 22 and removes the positioning plate 21 from the workbench 1. Then the operator removes the glass and separates the cut part of the glass from the glass body, and then repeats the above process to continue cutting the glass. After the glass cutting is completed, the positioning plate 21 is installed on the workbench 1, and the connecting rod 24 is connected to the telescopic sleeve 22.

[0065] Example 2: Based on Example 1, Figure 4 , Figure 8 and Fig. 9 As shown, it also includes: a mounting rod 31, which is fixed to the workbench 1, and the mounting rod 31 is fixed with a first push rod 32, and the telescopic end of the first push rod 32 is fixed with a first piston plate; a first fixed cylinder 33, which is fixed to the mounting rod 31, and the first piston plate at the telescopic end of the first push rod 32 is located in the first fixed cylinder 33 and slides; a first hydraulic telescopic rod 34, which has two, both of which are fixed to the mounting rod 31, and the fixed part of the first hydraulic telescopic rod 34 is connected to the first fixed cylinder 33, and the telescopic ends of the two first hydraulic telescopic rods 34 are respectively fitted with the upper and lower sides of the glass to detect the thickness of the glass; a trigger component, which is arranged on the mounting sleeve 9, and is used to change the squeezing force of the glass cutter 10 on the glass; a limiting ring 331 is fixed in the first fixed cylinder 33, and the limiting ring 331 is used to limit the first piston plate on the telescopic end of the first push rod 32.

[0066] In the above scheme, a method for detecting the thickness of hot-bent glass is proposed, so that the device can adapt to glass of different sizes and glass of different thicknesses; the mounting rod 31 is an L-shaped mounting frame; hydraulic oil is arranged between the first fixed cylinder 33 and the lower side of the first piston plate on the first push rod 32, and the limit ring 331 is located below the first piston plate on the first push rod 32, and the limit ring 331 is used to make the first piston plate on the first push rod 32 extend out a consistent distance each time; the two first hydraulic telescopic rods 34 are respectively located on the upper and lower sides of the mounting rod 31, so as to contact the inner and outer sides of the glass; the positioning plate 21 fixes the glass cutting part, so as to ensure the stability during the glass cutting process; the telescopic end of the first hydraulic telescopic rod 34 is provided with a rubber pad, so as to buffer the extrusion force applied to the glass to prevent the glass from being crushed.

[0067] Comparison Figure 2 , Figure 3 , Figure 6 , Figure 8 and Fig. 9 As shown, the trigger assembly includes: a second hydraulic telescopic rod 41, which is fixed in the mounting sleeve 9, an elastic member is arranged between the telescopic end of the second hydraulic telescopic rod 41 and the glass cutter 10, and the mounting sleeve 9 is slidably connected to the glass cutter 10; an oil guide pipe 42, which is connected between the second hydraulic telescopic rod 41 and the first fixed cylinder 33, and a pressure relief valve is installed on the oil guide pipe 42; a return pipe 43, which is connected to the first fixed cylinder 33, and a one-way valve is installed on the return pipe 43, and the return pipe 43 is connected to the oil guide pipe 42, and the pressure relief valve on the oil guide pipe 42 is located between the connection point between the return pipe 43 and the oil guide pipe 42 and the connection point between the oil guide pipe 42 and the first fixed cylinder 33.

[0068] In the above scheme, a method of adjusting the force applied by the glass cutter 10 to the glass is proposed, so that the device can be suitable for glasses of different thicknesses; the elastic member of the glass cutter 10 is a spring, and the pressure relief valve on the oil guide pipe 42 is used to allow hydraulic oil to pass through only when the pressure in the first fixed cylinder 33 reaches the threshold of the pressure relief valve, so that the hydraulic oil in the first fixed cylinder 33 can preferentially enter the two first hydraulic telescopic rods 34; the hydraulic oil in the second hydraulic telescopic rod 41 can enter the fixed cylinder 33 through the one-way valve on the return pipe 43.

[0069] Working principle: When placing the glass on the workbench 1, the operator controls the glass to move between the telescopic ends of the two first hydraulic telescopic rods 34. After the glass is fixed, the operator turns on the first push rod 32. The telescopic end of the first push rod 32 drives the first piston plate thereon to move downward. The first piston plate pushes the hydraulic oil in the first fixed cylinder 33, so that the hydraulic oil in the first fixed cylinder 33 flows into the two first hydraulic telescopic rods 34. The telescopic ends of the two first hydraulic telescopic rods 34 gradually extend outward. After the telescopic ends of the two first hydraulic telescopic rods 34 are in contact with the glass, the first hydraulic telescopic rods 34 are opened. The telescopic end of the retractor 34 cannot move. At this time, the telescopic end of the first push rod 32 continues to drive the first piston plate thereon to move downward, and the hydraulic oil pressure in the first fixed cylinder 33 increases. When the pressure in the first fixed cylinder 33 exceeds the threshold of the pressure relief valve on the oil guide pipe 42, the hydraulic oil in the first fixed cylinder 33 enters the second hydraulic telescopic rod 41 through the oil guide pipe 42. The telescopic end of the second hydraulic telescopic rod 41 extends and compresses the elastic part thereon, so that the elastic part accumulates force. At this time, the squeezing force applied by the glass cutter 10 to the glass increases. In this way, the squeezing force applied by the glass cutter 10 to the glass is adjusted according to the thickness of the glass.

[0070] As the telescopic end of the second hydraulic telescopic rod 41 gradually extends, that is, the telescopic end of the first push rod 32 continues to move downward, when the first piston plate on the telescopic end of the first push rod 32 contacts the limit ring 331, the first push rod 32 stops working. At this time, the glass thickness detection is completed, and the squeezing force of the glass cutter 10 on the glass is adjusted.

[0071] In the above process, as the thickness of the glass increases, the distance moved by the telescopic ends of the two first hydraulic telescopic rods 34 becomes shorter, so that more hydraulic oil in the first fixed cylinder 33 enters the second hydraulic telescopic rod 41, thereby increasing the compression of the elastic member between the glass cutter 10 and the telescopic end of the second hydraulic telescopic rod 41, and increasing the squeezing force applied by the glass cutter 10 on the glass.

[0072] After the glass cutting is completed, the operator controls the first push rod 32 to reset, so that the telescopic ends of the two first hydraulic telescopic rods 34 are reset and lose contact with the glass. During this process, the hydraulic oil in the second hydraulic telescopic rod 41 flows into the return pipe 43 through the oil guide pipe 42, and flows back to the first fixed cylinder 33 through the one-way valve on the return pipe 43, so that the squeezing force of the glass cutter 10 on the glass is restored to the initial state, and then the above steps are repeated to cut the next piece of glass.

[0073] Example 3: Based on Example 2, Fig.10 and Fig.11As shown, it also includes: a second push rod 51, fixedly connected to the workbench 1; a second fixed cylinder 52, fixedly connected to the workbench 1, the telescopic end of the second push rod 51 is fixedly connected to a second piston plate, and the second piston plate is located in the second fixed cylinder 52 and slides; a fixed sleeve 53, fixedly connected to the workbench 1, a three-way pipe 55 is connected between the fixed sleeve 53 and the second fixed cylinder 52, and both ends of the fixed sleeve 53 are sealed and slidably connected with a stabilizing member 54; a knocking assembly is arranged on the workbench 1, and is used to knock on the glass.

[0074] In the above scheme, a method of knocking on the cut glass is proposed to separate the cut part of the glass from the main body of the glass; the second push rod 51 has an active force, such as an electric push rod; the second fixed cylinder 52 and the left side of the second piston plate on the telescopic end of the second push rod 51 are filled with gas; the stabilizing member 54 is used to clamp and fix the cut part of the glass and detect the size of the glass; rubber pads are provided on the opposite sides of the upper parts of the two stabilizing members 54 to prevent the glass from being subjected to hard squeezing pressure.

[0075] Comparison Figure 3 , Fig.10 and Fig.11 As shown, the knocking assembly includes: a pneumatic telescopic rod 61, which is fixed to the workbench 1 and is connected to the three-way pipe 55; a knocking block 62, which is fixed to the telescopic end of the pneumatic telescopic rod 61. A hemispherical protrusion is provided on the upper side of the knocking block 62, so that the force on the glass is more concentrated, which facilitates the separation of the glass body and the cut part of the glass. An electric control valve 63 is installed at the three-way part of the three-way pipe 55. The electric control valve 63 is an existing device for controlling the flow direction of the gas in the three-way pipe 55. When the electric control valve 63 is in the initial state, the second fixed cylinder 52 is connected to the fixed sleeve 53 through the three-way pipe 55.

[0076] Working principle: before cutting the glass, the operator turns on the second push rod 51, and the telescopic end of the second push rod 51 drives the second piston plate thereon to move to the right, forming a negative pressure in the second fixed cylinder 52 and extracting the gas in the fixed sleeve 53, and the gas in the fixed sleeve 53 enters the second fixed cylinder 52 through the three-way pipe 55 and the electric control valve 63, the gas in the fixed sleeve 53 is reduced, and the two stabilizing parts 54 move towards each other until both stabilizing parts 54 are in contact with the glass and then stop moving. At this time, the telescopic end of the second push rod 51 continues to move and forms a negative pressure in the fixed sleeve 53, so that the two stabilizing parts 54 clamp the glass and apply a squeezing force until the telescopic end of the second push rod 51 moves to the specified position, the second push rod 51 is closed, and the glass cutting operation is started.

[0077] After the glass is cut, the second push rod 51 is opened and the electric control valve 63 is adjusted to make the second fixed cylinder 52 lose communication with the fixed sleeve 53, the second fixed cylinder 52 is connected with the pneumatic telescopic rod 61, the telescopic end of the second push rod 51 moves to the left, and the second piston plate of the second push rod 51 squeezes the gas in the second fixed cylinder 52. The gas in the second fixed cylinder 52 enters the pneumatic telescopic rod 61 through the three-way pipe 55 and the electric control valve 63. The gas in the pneumatic telescopic rod 61 increases, and its telescopic end moves upward. The pneumatic telescopic rod 61 drives the knocking block 62 to move upward until the knocking block 62 contacts the glass, and then the knocking block 62 stops moving. In this process, the knocking block 62 knocks on the glass. In the above process, the two stabilizing members 54 apply a clamping force to the lower side of the glass, causing the stress of the glass to change. Then, through the knocking of the knocking block 62, the separation of the glass cutting part is accelerated, thereby reducing the workload of the operator and improving the efficiency of glass cutting.

[0078] After the glass cutting is completed, the second push rod 51 is opened to retract the telescopic end of the second push rod 51, thereby retracting the telescopic end of the pneumatic telescopic rod 61, until the telescopic end of the second push rod 51 is reset, the telescopic end of the second push rod 51 is controlled to extend, and the electric control valve 63 is adjusted to connect the second fixed cylinder 52 with the fixed sleeve 53, the telescopic end of the second push rod 51 drives the second piston plate to move and pushes the gas in the second fixed cylinder 52 into the fixed sleeve 53, so that the two stabilizing members 54 are separated and lose contact with the glass, until the telescopic end of the second push rod 51 returns to its original position, and the second push rod 51 is closed.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the invention.
