Description

Technical Field

[0001] The invention relates to LCD glass substrate processing equipment, in particular to a cutting equipment for LCD glass substrate processing. Background Art

[0002] LCD (liquid crystal display) glass substrate is one of the key components of liquid crystal display, mainly used to carry liquid crystal materials and form display images. LCD glass substrate is usually composed of two ultra-thin glass plates. The processing of LCD glass substrate requires first cutting the large piece of glass into the required size, then removing impurities and contaminants on the glass surface, and then coating the glass surface with a transparent conductive layer (ITO), and forming an electrode pattern through a photolithography process, and then coating the ITO layer with an orientation layer, and orienting the liquid crystal molecules through friction or photo-orientation technology, and finally aligning the two glass substrates, injecting liquid crystal material in the middle, and sealing the edges.

[0003] In the process of cutting glass substrates, it is traditional to transport the glass to the cutting position through a whole-surface conveyor belt, and cut the glass into the required size through precise control of the cutter. However, the glass cannot be completely split during cutting in this way, and a certain space needs to be left to avoid cutting the conveyor belt, so that workers need to break the two sides of the glass apart after cutting. The existing part adopts a multi-belt transmission method, by synchronizing the speed of each narrow conveyor belt, so that there is a certain gap between the glasses to be cut, so that the cutter can cut to the bottom, without the operation of breaking the glass later, and reducing labor costs. However, this penetrating splitting method is likely to cause the glass to shake at the moment of splitting, and then shake the conveyor belt to affect the transmission of the rear end glass, and it is also easy to affect the quality of glass cutting, so that part of the glass edge is affected by the grinding effect of the cutter, affecting the imaging effect of the glass.

[0004] Therefore, this case aims to provide a cutting device for LCD glass substrate processing, which can not only limit and separate the glass to be cut, but also correctly guide the glass to be input at the rear end, so as to ensure the edge accuracy of the glass cutting and improve the glass imaging quality.

The front correction structure includes two sets of limit frames arranged in the gap between the conveyor belts. The lower ends of the limit frames are slidably installed on a middle frame. A middle matching piece is arranged on the middle frame. The lower matching piece cooperates with the middle matching piece after being pushed out.

The transverse mounting plate is movably provided with a plurality of adjusters, and the adjusters divide the transverse mounting plate into a plurality of areas.

[0011] As a further improvement, a chute is provided on the transverse mounting plate, and a rib groove is provided in the chute. The regulator includes an adjustment frame slidably arranged in the chute, a through hole is provided in the middle of the adjustment frame, and an abutment pin passes through the through hole and is locked to the bottom of the inner side of the chute.

[0012] As a further improvement, the lifting platform includes an upper lifting seat and a lower lifting seat fixed on the adjustment frame, the upper lifting seat and the lower lifting seat are driven by different motors, the upper lifting seat is connected to the front end guide member, and the lower lifting seat is connected to the rear end guide member.

[0013] As a further improvement, the front end guide member includes two front L-shaped limit buckles arranged at intervals on the upper lifting seat, and the two front L-shaped limit buckles are connected to front shock-absorbing strips.

[0014] As a further improvement, the rear end guide member includes two rear L-shaped limit buckles arranged at intervals on the lower lifting seat, the two rear L-shaped limit buckles are connected to rear shock-absorbing strips, and the inner sides of the two rear L-shaped limit buckles are connected to gap support members.

[0015] As a further improvement, the gap support member includes a U-shaped groove connected to the rear end guide member, the opening of the U-shaped groove is opposite to the position of the cutter, the tops of both ends of the U-shaped groove opening are locked with inner top strips, and the elastic member is located in the middle position of the lower part of the U-shaped groove.

[0016] As a further improvement, the limit frame includes a side limit plate arranged on the outermost edge of the conveyor belt, and the side limit plate extends downward to form an L-shaped corner frame, and the L-shaped corner frame is slidably connected to the top of the middle frame.

[0017] As a further improvement, the middle fitting is a tubular cavity, and the opening of the tubular cavity at one end close to the lower fitting is larger than the opening at the side close to the middle frame.

[0018] As a further improvement, the lower matching component includes a push rod motor fixed on the outer side of the lower lifting seat, and the output end of the push rod motor is connected to a docking cone, and the docking cone is clamped in the tubular cavity after being pushed out.

[0019] The beneficial effects of the present invention are:

[0020] In the existing glass cutting equipment that adopts the belt-type, the penetrating force when cutting is completed can easily cause the glass to tilt, thereby causing the cutter to damage the cut glass and affecting the imaging quality of the glass. Therefore, the present invention sets an inner edge support structure. When the glass moves to the lower end position of the cutter, the transmitted glass is firstly limited by lifting the front guide member, and then the rear end guide member at the rear end is raised to limit and fix the two sides of the glass. When the rear end guide member rises, the gap support member is also driven to rise, so that the gap support member is close to the lower side of the glass, and the setting position of the gap support member is cut below the cutting end, so that the cutter can directly sink into the gap support member, and the gap support member supports the glass, so that the glass can be in a relatively stable state at the moment of being cut.

[0021] Since a glass substrate is generally cut into multiple pieces, and the sizes of glass substrates with different requirements are different, the present invention sets multiple regulators at the lower end of the conveyor belt, so that one regulator can correspond to a glass cutting area, so that each glass cutting area can receive a corresponding effect.

[0022] As mentioned above, different glass substrates have different size requirements, so the position of the adjuster is not fixed. In order to adapt to the sizes of different glass substrates, the adjuster of the present invention is slidably arranged with the horizontal mounting plate, so that the adjuster can be moved to the required position. At the same time, in order to avoid the adjustment of the move during the cutting process, the adjuster is fixed by abutting pins to ensure that the adjuster is not easily displaced during cutting.

[0023] Since the front guide and the rear guide are lifted separately, they cannot be installed on the same lifting structure. Therefore, although they are installed on the same lifting platform, they are installed on the upper lifting seat and the lower lifting seat respectively, so that the rise of the upper lifting seat does not affect the lower lifting seat, and the stability of the two is maintained.

[0024] When the gap support member supports the glass, it first needs to make way for the cutter to ensure smooth cutting. Therefore, the gap support member of the present invention is a structure with a middle groove, so that the cutter can sink into the U-shaped opening of the gap support member after cutting is completed. In order to stably contact the glass, the two ends of the top of the gap support member also need flexible inner top strips to contact the glass. Because the span of the entire U-shaped groove is too large, and the other end of the U-shaped groove cannot be attached to the front end guide member, an elastic member is arranged in the middle position of the bottom end of the U-shaped groove. Through the support of the elastic member, the supporting force of the front and rear ends of the U-shaped groove is relatively uniform when supporting the ratio.

[0025] In the process of glass cutting, practically all conveyor belts will be in a shaking state. Although the glass being cut is relatively stable due to the fixation of the front guide and the rear guide, the glass waiting at the front end is prone to shaking, resulting in a slight deviation in the originally calibrated position. Once the deviation occurs, the cutting process is prone to uneven cutting areas, making the glass substrate waste. Therefore, the present invention provides a front correction structure based on the inner edge support structure. When the rear guide rises into place, the lower matching piece and the middle matching piece are in the same straight line. Through the cooperation of the lower matching piece and the middle matching piece, the position of the limit frame is fixed before cutting, thereby fixing the glass substrate waiting for processing in the limit frame. Even if the conveyor belt vibrates, it will not affect the position of the front glass substrate, thereby improving the accuracy of glass cutting from another aspect.

[0026] In the process of limiting the front end glass, in fact, the normal transmission path of the glass will not deviate at the beginning. Only when the closest piece of glass is cut will a slight offset occur. Therefore, the limit frame of the present invention is only set on the glass at the front end of the cutting position. The limit plate has a certain sliding distance, so it can better adapt to the glass when it initially contacts the glass. It can slide slightly on the middle frame through the L-shaped corner frame without causing hard obstacles to the glass.

[0027] In order to facilitate the cooperation between the middle matching part and the lower matching part, the present invention sets the middle matching part as a trumpet-shaped tubular cavity, so as to facilitate the contact and cooperation of the lower matching part. The lower matching part will only be displaced after the lower lifting seat is lifted to the corresponding height, and the structure that cooperates with the tubular cavity segment is a docking cone, which fits tightly after cooperation, not only making it easy to connect in the early stage, but also not prone to detachment and jumping in the later stage.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] Reference Figure 1 to Figure 6As shown, a cutting device for processing LCD glass substrates comprises a conveyor 10, on which a plurality of conveyor belts 20 are arranged, and the conveyor belts 20 are arranged at intervals. A gantry mounting platform 30 is arranged above the conveyor 10, and a plurality of cutters 31 are arranged on the inner side of the gantry mounting platform 30. The cutting device also comprises: an inner support edge support structure 40, wherein the conveyor belt 20 comprises conveyor wheels arranged at both ends, and a belt body connected to both ends of the conveyor wheels, and the inner support edge support structure 40 comprises a transverse frame 41 arranged on the inner side of the belt body, and the two ends of the transverse frame 41 are fixed to the inner side wall of the conveyor 10, and a lifting platform 42 is arranged at the upper end of the transverse frame 41 corresponding to the gap between the two conveyor belts 20, and the front end and the rear end of the lifting platform 42 are respectively provided with front end guides. The front guide member 43 and the rear guide member 44 are arranged on the front end of the gantry mounting table 30, and the rear guide member 44 is arranged on the rear end of the gantry mounting table 30. The front guide member 43 and the rear guide member 44 are arranged on the rear end of the gantry mounting table 30. The rear guide member 44 is raised after the front guide member 43 is pressed against the glass substrate. The rear guide member 44 is connected with a gap support member 45. The middle part of the gap support member 45 is supported by an elastic member 46. When the front guide member 43 and the rear guide member 44 are in the same straight line, the gap support member 45 is located at the lower end of the glass to be cut. The front correction structure 50 is located at the front end of the gantry mounting table 30, and a lower matching member 47 is arranged on the outer side of the rear guide member 44. The front correction structure 50 includes two groups of limit frames 51 arranged in the gap between the conveyor belts 20. The lower end of the limit frame 51 is slidably mounted on a middle frame 52. The middle frame 52 is provided with a middle matching member 53. After the lower matching member 47 is pushed out, it matches with the middle matching member 53.

[0040] The entire glass substrate is transported forward by a plurality of conveyor belts 20 until it reaches the lower end of the cutter 31, where it is fixed under the limit of the inner edge support structure 40. Before cutting, the front end of the glass is limited in the horizontal position by the front correction structure 50, and then the cutter 31 is lowered to start cutting.

[0041] In the existing glass cutting equipment using a split-belt type, the penetrating force when cutting is completed can easily cause the glass to tilt, thereby causing the cutter to damage the cut glass and affecting the imaging quality of the glass. Therefore, in this embodiment, the inner edge support structure 40 is set. When the glass moves to the lower end position of the cutter 31, the transmitted glass is firstly limited by lifting the front guide 43, and then the rear guide 44 at the rear end is raised to limit and fix the two sides of the glass. When the rear guide 44 rises, the gap support 45 is also driven to rise, so that the gap support 45 is close to the lower side of the glass, and the gap support 45 is set below the cutting end, so that the cutter 31 can be directly sunk into the gap support 45, and the gap support 45 supports the glass, so that the glass can be in a relatively stable state at the moment of being cut.

[0042] Since a glass substrate is generally cut into multiple pieces, and the sizes of glass substrates required for different needs are different, the horizontal frame 41 of this embodiment includes a mounting buckle seat 411 locked on the inner side of the conveyor 10, and a horizontal mounting plate 412 is connected to the two mounting buckles 411. The horizontal mounting plate 412 is movably provided with a plurality of adjusters 413. The adjusters 413 divide the horizontal mounting plate 412 into a plurality of areas. By providing a plurality of adjusters 413 at the lower end of the conveyor belt 20, one adjuster 413 can correspond to a glass cutting area, so that each glass cutting area can be affected by the corresponding effect.

[0043] As mentioned above, different glass substrates have different size requirements, so the position of the adjuster 413 is not fixed. In order to adapt to the sizes of different glass substrates, a chute is provided on the horizontal mounting plate 412 of this embodiment, and there is a rib groove in the chute. The adjuster 413 includes an adjusting frame 4131 slidably arranged in the chute, and a through hole is provided in the middle of the adjusting frame 4131, and an abutment pin 4132 penetrates the through hole and is locked to the bottom of the inner side of the chute. The adjuster 413 and the horizontal mounting plate 412 are slidably arranged, so that the adjuster 413 can be moved to the required position. At the same time, in order to avoid the phenomenon of the adjuster 413 being out of position during the cutting process after being moved, the adjuster 413 after being moved is also fixed by the abutment pin 4132 to ensure that the adjuster 413 is not easily displaced during cutting.

[0044] Since the front end guide 43 and the rear end guide 44 are lifted and lowered separately, the two cannot be installed on the same lifting structure. Therefore, although the two are installed on the same lifting platform 42, the lifting platform 42 includes an upper lifting seat 421 and a lower lifting seat 422 fixed on the adjustment frame 4131, and the upper lifting seat 421 and the lower lifting seat 422 are driven by different motors. The upper lifting seat 421 is connected to the front end guide 43, and the lower lifting seat 422 is connected to the rear end guide 44. The front end guide 43 and the rear end guide 44 are respectively installed on the upper lifting seat 421 and the lower lifting seat 422, so that the rise of the upper lifting seat 421 does not affect the lower lifting seat 422, thereby maintaining the stability of the two.

[0045] The front end guide 43 has a similar structure to the rear end guide 44. Specifically, the front end guide 43 includes two spaced front L-shaped limit buckles 431 arranged on the upper lifting seat 421, and the two front L-shaped limit buckles 431 are connected to a front shock absorbing strip 432. The rear end guide 44 includes two spaced rear L-shaped limit buckles 441 arranged on the lower lifting seat 422, and the two rear L-shaped limit buckles 441 are connected to a rear shock absorbing strip 442. The inner sides of the two rear L-shaped limit buckles 441 are connected to a gap support 45, so that the glass substrate to be cut can be fixed at both ends through the four L-shaped limit buckles. It should be emphasized that the two front L-shaped limit buckles 431 and the two rear L-shaped limit buckles 441 are arranged on both sides of the cutting line, so they will not hinder the cutting action.

[0046] When the gap support member 45 supports the glass, it first needs to give way to the cutter 31 so as to ensure the smooth cutting action. Therefore, the gap support member 45 of this embodiment includes a U-shaped groove 451 connected to the rear end guide member 44, the opening of the U-shaped groove 451 is directly opposite to the position of the cutter 31, and the tops of both ends of the opening of the U-shaped groove 451 are locked with inner top strips 452. The elastic member 46 is located in the middle of the lower part of the U-shaped groove 451. The gap support member 45 is a structure with a middle groove, and thus To allow the cutter to sink into the U-shaped opening of the gap support 45 after the cutting is completed, and in order to stably contact the glass, the two ends of the top of the gap support 45 also need flexible inner top strips 452 to contact the glass. Because the span of the entire U-shaped groove 451 is too large, and the other end of the U-shaped groove 451 cannot be attached to the front end guide 43, an elastic member 46 is provided in the middle position of the bottom end of the U-shaped groove 451. Through the support of the elastic member 46, the supporting force of the front and rear ends of the U-shaped groove 451 is more uniform when supporting the proportion.

[0047] In the process of glass cutting, practically all the conveyor belts 20 will be in a shaking state. Although the glass being cut is relatively stable due to the fixation of the front guide 43 and the rear guide 44, the glass waiting at the front end is prone to shaking, resulting in a slight deviation in the originally calibrated position. Once the deviation occurs, the cutting process is prone to uneven cutting areas, making the glass substrate waste. Therefore, the present invention provides a front correction structure 50 based on the inner edge support structure 40. When the rear guide 44 rises to its position, the lower matching piece 47 and the middle matching piece 53 are in the same straight line. Through the cooperation of the lower matching piece 47 and the middle matching piece 53, the position of the limit frame 51 is fixed before cutting, thereby fixing the glass substrate waiting for processing in the limit frame 51. Even if the conveyor belt 20 vibrates, it will not affect the position of the front glass substrate, thereby improving the accuracy of glass cutting from another aspect.

[0048] In the process of limiting the front end glass, in fact, at the beginning, the normal transmission path of the glass will not deviate. Only when cutting, the closest piece of glass will be slightly offset. Therefore, the limit frame 51 of this embodiment includes a side limit plate 511 arranged on the edge of the outermost conveyor belt 20. The side limit plate 511 extends downward to be provided with an L-shaped corner frame 512. The L-shaped corner frame 512 is slidably connected to the top of the middle frame 52. The limit frame 51 is also only arranged on the glass at the front end of the cutting position. The side limit plate 511 has a certain sliding distance. Therefore, it can better adapt to the glass when it initially contacts the glass. It can slide slightly on the middle frame 52 through the L-shaped corner frame 512 without causing hard obstacles to the glass.

[0049] In order to facilitate the cooperation between the middle fitting 53 and the lower fitting 47, the middle fitting 53 of this embodiment is a tubular cavity, and the opening of the tubular cavity close to the lower fitting 47 is larger than the opening close to the middle frame 52. The middle fitting 53 is set to a trumpet-shaped tubular cavity, so as to facilitate the contact and cooperation of the lower fitting 47. The lower fitting 47 is specifically as follows: the lower fitting 47 includes a push rod motor 471 fixed on the outside of the lower lifting seat 422, and a docking cone 472 is connected to the output end of the push rod motor 471. The docking cone 472 is clamped in the tubular cavity after being pushed out, and will only be displaced after the lower lifting seat 422 is lifted to the corresponding height. The structure that cooperates with the tubular cavity segment is the docking cone 472, which fits tightly after cooperation, which is not only easy to connect in the early stage, but also not easy to separate and jump in the later stage.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
