DETAILED DESCRIPTION
[0048] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0049] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.
[0050] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:
[0051] Example 1
[0052] Reference Attachment Figure 1 , the ultra-thin glass cutting device provided in this embodiment includes a cutting base 1, a transfer component 4 and a docking component, wherein the cutting base 1 is alternately provided with supporting blocks 13 and docking grooves 12 along its width direction, and the upper surfaces of several supporting blocks 13 are at the same height to form a supporting surface 11 for supporting the glass plate; the transfer component 4 is continuously arranged with the cutting base 1, and is used to transfer the glass plate between the transfer vehicle (not shown in the figure) and the cutting base 1; the docking component includes a docking frame 5, which is movably arranged on the transfer component 4, and includes several docking members 51 arranged at intervals along the width direction of the transfer component 4, and the docking members 51 are adapted to the docking grooves 12; the docking component can reciprocate relative to the transfer component 4 along the transfer direction, and the docking component can reciprocate relative to the transfer component 4 along the transfer surface of the transfer component 4 to transfer the glass plate back and forth between the transfer component 4 and the supporting surface 11;
[0053] Among them, the docking rack 5 can lift the glass plate on the transfer component 4 according to the docking instruction, translate it to the top of the supporting surface 11, and descend into the docking groove 12 so that the glass plate is supported by the supporting surface 11 and translates back to the side of the transfer component 4.
[0054] It is understandable that in order to solve the problem that the existing grabbing and conveying means are no longer suitable for ultra-thin glass and cannot guarantee the safety of the coated surface and the chemically tempered surface, this embodiment provides an ultra-thin glass cutting device, which is a fully automatic control device. It can automatically convey the glass plate to ensure that the coated surface and the tempered surface will not be damaged during the conveying process of the glass plate, thereby ensuring the safety of the glass plate and improving the conveying and cutting efficiency.
[0055] Among them, this embodiment targets ultra-thin glass, which can be a glass plate with a thickness not exceeding 2 mm. Of course, glass plates of other thicknesses are also suitable for the cutting device provided by this embodiment.
[0056] The cutting base 1 is a rigid structure, which can be a table structure, a platform structure, a frame structure, etc., which can provide a supporting surface 11. The supporting surface 11 is a plane, which can be a supporting surface composed of a plurality of discontinuous but equal-height supporting blocks 13. The supporting block 13 is a rigid structure, and its shape is not limited here, and can be Figure 1 and Figure 2 The rectangle shown can also be any other shape, as long as the upper surfaces of the supporting blocks 13 are flush and can form the supporting surface 11; the supporting blocks 13 can be formed by digging the connecting grooves 12 on the surface of the cutting base 1, or they can be raised structures formed by additional bonding or welding on the surface of the cutting base 1. In this embodiment, the dimensions of the supporting blocks 13 and the connecting grooves 12 in the width direction of the cutting base 1 can be the same or different. For example, a connecting groove 12 with a width of 150 mm and a depth of 150 mm is set at every 150 mm. The design can be adjusted according to actual needs and is not limited here; refer to the attached Figure 1 and attached Figure 2 In this embodiment, a cover 6 can be disposed outside the cutting base 1. The cover 6 has a slot, with the cutting base 1 partially positioned within the slot. The cooperating laser emitting assembly 3 can be movably mounted on the top wall of the slot, thereby forming a laser cutting area within the slot. The slot also provides a certain degree of protection for the glass sheet, preventing damage to the glass edge. The shape and size of the cutting base 1 and the cover 6 are not limited and can be designed and adjusted according to actual needs. In this embodiment, a protective film layer can also be attached to the supporting surface 11, which can be, but is not limited to, Teflon, to prevent scratches or wear on the glass itself.
[0057] The transfer assembly 4 has a transmission function, which can be a conveyor belt, conveyor rollers, or other conveying method. Specifically, it transfers the glass sheet from the transfer vehicle to the cutting base 1 for laser cutting. During this process, the glass is kept as contactless as possible, that is, direct squeezing, contact, and gripping of the coated and chemically tempered surfaces are avoided. In this embodiment, the non-coated and non-tempered surfaces of the glass sheet can be automatically supported and transferred via a conveyor belt. It is not difficult to understand that the drive mechanism of the transfer assembly 4 can be electronically controlled by the controller 2 to achieve automatic control of the glass sheet transfer. Accordingly, the timing of the controller 2 controlling the transfer assembly 4 can be obtained by a related position sensor or electromagnetic switch, or it can be manually controlled or manually input into the controller 2.
[0058] The connecting assembly is capable of moving relative to the transfer assembly 4, which may be, but is not limited to, translation, lifting, etc. It is capable of lifting the glass sheet to separate it from the transfer assembly 4 and transfer it to the supporting surface 11 of the cutting base 1, making the transportation and transfer of the glass sheet a fully automatic process. This is not only efficient but also eliminates the need for a robotic arm to grasp the glass sheet, effectively ensuring the safety of the glass sheet. For example, the connecting assembly can be set at the end of the transfer assembly 4 to receive the glass sheet, and then transfer the glass sheet to the side of the cutting base 1 by lifting or by a combination of translation and lifting. For another example, the connecting assembly can be set within the transfer assembly 4, capable of lifting and translating relative to the transfer assembly 4, lifting the glass sheet relative to the transfer assembly 4, then translating it to the side of the cutting base 1, and then lowering it to place the glass sheet on the supporting surface 11. Accordingly, the connecting member 51 is a rigid structure, which can be a rod-shaped structure or a plate-shaped structure that is compatible with the connecting groove 12. In this embodiment, the controller 2 can be used to control the docking frame 5 to lift relative to the transfer component 4 so that the docking member 51 supports the glass plate so that it is separated from the support of the transfer component 4, and then the docking frame 5 is controlled to move horizontally toward the cutting base 1. After reaching the position, the docking frame 5 is lowered so that the glass plate falls on the supporting surface 11, and the docking member 51 falls into the docking groove 12 and is separated from the glass substrate, completing the transfer of the glass substrate to the cutting base 1; accordingly, after the glass plate is cut on the cutting base 1, the controller 2 can be used to control the docking frame 5 to move in the reverse direction to transfer the glass substrate to the transfer component 4, and then it can be transferred to the splitting process through the transfer component 4, or it can be transferred to the transfer vehicle through the transfer component 4. It is not difficult to understand that the docking instruction can be generated and issued by the controller 2, for example: the controller 2 can generate and send a docking instruction to the docking component based on the position of the glass plate, so that the docking component moves relative to the transfer component 4.
[0059] According to the above, the ultra-thin glass cutting device provided by the present application sets the cutting base 1 in the form of alternating support blocks 13 and connecting grooves 12, and correspondingly sets the connecting frame 5 in the form of multiple spaced connecting pieces 51, so that when the glass plate is transferred between the transfer component 4 and the cutting base 1, the connecting pieces 51 can be used to support the back of the glass plate to complete the transfer, without the need to grab or turn the glass plate over for transfer, greatly improving the safety of the glass plate transfer and preventing bumps or wear on the coated surface or chemically tempered surface. This solves the problem that the existing grabbing-type transfer method is no longer suitable for ultra-thin glass and cannot guarantee the safety of the coated surface and chemically tempered surface.
[0060] Further, refer to the attached Figure 1 The ultra-thin glass cutting device provided in this embodiment, in a specific implementation, further includes a controller 2 and a laser emitting component 3; the laser emitting component 3 is movably arranged above the supporting surface 11 and spaced apart from the supporting surface 11; the controller 2 is signal-connected to the laser emitting component 3 to issue a control instruction to the laser emitting component 3 to cause it to emit a cutting laser toward the supporting surface 11; wherein the focus of the laser moves in a waveform along the thickness direction of the glass plate in any straight line direction parallel to the plate surface of the glass plate.
[0061] It is understood that in order to address the problem of low product yield, such as burrs or cracks, that occurs with traditional laser straight-line cutting of ultra-thin glass, this embodiment can dynamically adjust the focal length of the laser emission so that the focal point of the laser focus fluctuates up and down at the key point of the glass sheet thickness. This allows the laser to form a wavy cutting line within the glass sheet, extending the cutting line path and thereby increasing the heat applied within the glass sheet, evenly distributing the heat, thereby reducing the difficulty of splintering, effectively reducing the generation of burrs and cracks, and significantly improving product yield. Accordingly, the controller 2 is a PLC controller capable of data transmission and reception, analysis, comparison, and program editing. The laser emission assembly 3 can include a light source emitter and a dynamic zoom lens barrel, so that the light source emitter can achieve focal length changes through the dynamic zoom lens barrel. The configuration of this focal length change is readily understood and implemented by those skilled in the art and is not further elaborated here. In this embodiment, the laser emission assembly 3 can also be equipped with a guide rail, a slider, and a drive motor to achieve horizontal movement of the light source emitter above the cutting base 1. The above-mentioned structural configuration is readily understood by those skilled in the art and is not further elaborated here. Furthermore, the controller 2 is electrically connected to the driving motor of the laser emitting assembly 3, the laser emitter, and the dynamic zoom lens barrel, so as to be able to control the light source emitter to move horizontally while changing the focal length according to the position information of the glass plate relative to the cutting base 1; the position information of the glass plate relative to the cutting base 1 can be transmitted to the controller 2 by a position sensor or sent or input into the controller 2 by manual control; accordingly, the controller 2 is preset with a waveform motion trajectory formula of the laser focus, and the focus of the laser is adjusted according to formula (1);
[0062]
[0063] Y=y+α (3)
[0064] Where: α is the vertical coordinate value of the laser focus in the base coordinate system; h is the thickness of the glass plate, h≤2mm; x is the horizontal coordinate value of the laser moving direction in the base coordinate system; m is the glass plate related constant, 5≤m≤500;
[0065] y is the vertical coordinate value of the lower surface of the glass plate in the base coordinate system; r is the arc radius of the glass plate's gravity depression; d1 is the distance between the lowest point of the glass plate's gravity depression and the upper surface of the base; x is the horizontal coordinate value of the laser focus in the moving direction of the base coordinate system; n is the nth gravity depression position of the glass plate; d3 is the width of the glass plate's gravity depression; d4 is the base support width between adjacent glass plate depressions; Y is the vertical coordinate value of the glass plate's depression corresponding to the laser focus in the base coordinate system;
[0066] Reference Attachment Figure 6The base coordinate system is a coordinate system with the support surface 11 as the zero reference plane. The X direction is the horizontal movement direction of the laser emitting assembly 3 when cutting the glass sheet, and the Y direction is the movement direction of the focus of the laser emitting assembly 3 when cutting the glass sheet, which is also the thickness direction of the glass. In this embodiment, the laser focus is set to fluctuate up and down based on the center of the glass thickness, and thus simulated to be a sinusoidal form. The movement distance of the focus is related to the glass thickness, and the glass thickness and the vertical coordinate value of the focus in the base coordinate system are thus simulated to have a linear relationship. Through linear fitting, t=12-5h is obtained, and in this embodiment, t can be selected as an integer value by rounding off. For example, when the corresponding glass thicknesses are 0.02mm, 0.2mm, 0.4mm, 0.6mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, and 2mm, t is 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, and 2, respectively. Furthermore, for ultra-thin glass, its overall thickness is relatively small, and excessive fluctuation amplitude can easily cause damage to the glass surface, affecting cracks and even product yield. Therefore, in this embodiment, a glass plate-related constant m is set, where 1 / m is the maximum distance that the laser focus moves up and down based on h / 2. The thinner the glass, the smaller 1 / m is required, and the larger m is, that is, the smaller the amplitude of the waveform trajectory. In this embodiment, m is determined to have the above-mentioned value range of 5-500 through experiments, simulations, and cutting effects, for example, m=10. It should be noted that the value of m is related to the composition of the glass. The higher the strength of the glass, the smaller the m value. For example, the m value of soda-lime-silica glass is greater than that of aluminum glass, and the m value of aluminum glass is greater than that of high-borosilicate glass. Of course, it can also be transformed into a corresponding cosine expression based on formula (1). This transformation is easily understood and implemented by those skilled in the art, and will not be elaborated on here. Furthermore, when the ultra-thin glass is supported by the supporting surface 11 of the cutting base 1, the glass plate will be depressed to a certain extent by gravity at the position corresponding to the connecting groove 12 due to its small thickness when supported by the supporting block 13, that is, the midpoint of the thickness of the glass will no longer remain on a straight line. In this state, the position of the focus needs to be adjusted accordingly based on formula (1) to ensure that the focus can accurately change the position of the center of the glass thickness to avoid burrs or cracks. It is not difficult to understand that d3 and d4 can be obtained based on the actual structural dimensions of the cutting base 1. In this embodiment, d3 and d4 can be equal or unequal; d1 can be automatically obtained by laser ranging; refer to the attached Figure 6 In the base coordinate system, take the first connecting groove 12 as an example. The glass plate is concave downward here. The distance from the lowest point to the supporting surface 11 is d1. The radius of the arc is r. The distance from the center of the circle to the supporting surface 11 is d2. The width of the connecting groove 12 is d3. The width of the supporting block 13 is d4. The width of the supporting block 13 before the connecting groove 12 can be obtained according to the actual structural dimensions. For example, in this embodiment, it can be proposed to be d4 / 2. Then Then find r, and the coordinates of the center of the arc caused by the glass downward due to gravity in the device software are (a, b), such as Figure 6 As shown, the coordinates of the center of the circle corresponding to the first connecting groove 12 are (a1, b1). b1=r-d1, and the corresponding circular coordinates of the nth connecting slot 12 are (a n , b n ), a n =(2n-1)a1,b n = r-d1, the corresponding circle formula (xa n )2+(yb n )2=r 2 , where x and y are the corresponding horizontal and vertical coordinates during the movement of the focus of the running laser, respectively, and then the above formula (2) is derived, and y is used to show the vertical coordinate value of the lower surface of the glass plate in the base coordinate system, and then the glass plate obtains the position change of the thickness midpoint in the connecting groove 12, and then combined with formula (1), the position change of the glass plate in the connecting groove 12 corresponding to the focus can be obtained. Then, in the area corresponding to the supporting block 13, the trajectory of the laser focus fluctuates up and down based on the horizontal line, and in the area corresponding to the connecting groove 12, the trajectory of the laser focus fluctuates up and down based on the concave arc line. And it is not difficult to understand that when the width of the supporting block 13 before the connecting groove 12 changes, formulas (2) and (3) can change accordingly, and this change belongs to the protection content of this embodiment. Refer to the attached Figure 7 The glass edge obtained by using traditional laser cutting devices and methods has many burrs and cracks. Figure 8 The glass edge obtained by using the cutting device and method provided in this embodiment is flat and smooth, and the product yield is greatly improved.
[0067] Further, refer to the attached Figure 3 In the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, the transfer component 4 includes a plurality of conveyor belts 41 arranged at intervals along its width direction, and the plurality of conveyor belts 41 move synchronously; the plurality of connecting pieces 51 of the connecting rack 5 and the plurality of conveyor belts 41 are alternately arranged in the width direction of the transfer component 4, so that the connecting rack 5 can be lifted and lowered back and forth relative to the transfer component 4 between adjacent conveyor belts 41.
[0068] It can be understood that in order to achieve the ability of the connecting component to translate and lift relative to the transfer component 4 without affecting the normal movement of the transfer component 4, the transfer component 4 in this embodiment is configured to include a plurality of spaced conveyor belts 41, and then the connecting piece 51 can be arranged alternately with the conveyor belts 41, and the connecting piece 51 can be lifted and lowered between adjacent conveyor belts 41 to avoid interference between the movements of the two.
[0069] Further, refer to the attached Figure 3 In the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, the transmission component 4 includes a first drive motor 42, a synchronous belt 43, a synchronous wheel 44 and a shaft 45; the two shafts 45 are spaced apart and parallel to each other along the transmission direction of the transmission component 4, and a plurality of synchronous wheels 44 are provided on the shaft 45 along its axial interval and rotate; the conveyor belt 41 is simultaneously sleeved on the two opposite synchronous wheels 44 on the two shafts 45; the synchronous belt 41 is simultaneously connected to the output end of the first drive motor 42 and any one of the synchronous wheels 44 to synchronously drive a plurality of the conveyor belts 41.
[0070] It is understood that the synchronous drive of the multiple conveyor belts 41 can be achieved by a first drive motor 42 in conjunction with a synchronous belt 43, synchronous pulleys 44, and a shaft 45. The first shaft 45 and the second shaft 45 are arranged parallel and opposite to each other. The shaft 45 is provided with multiple synchronous pulleys 44 rotating along its axial direction. One synchronous pulley 44 on the first shaft 45 (or a separately provided driving pulley) is connected to the output end of the first drive motor 42 via a synchronous belt 43. The other synchronous pulleys 44 are connected to the conveyor belts 41 in a one-to-one correspondence. When the first drive motor 42 is started, the synchronous pulleys 44 rotate around the shaft 45 to drive the conveyor belts 41 to move around the two shafts 45 to convey the glass sheets. Of course, it is not difficult to understand that the synchronous pulleys 44 are also equipped with bearings. It is also not difficult to understand that in this embodiment, the first drive motor 42 is connected to the controller 2 by signal, realizing automatic start and stop control.
[0071] Further, refer to the attached Figure 3 and attached Figure 4 In the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, the transfer component 4 includes a frame 46, and the plurality of conveyor belts 41 and the docking component are all arranged on the frame 46; the docking component also includes a first base 52 and a first lifting component 53; the first base 52 is movably connected to the frame 46, and the first base 52 can reciprocate relative to the frame 46 along the conveying direction of the transfer component 4; the first end of the first lifting component 53 is connected to the first base 52, and the second end is connected to the docking rack 5, so that the docking rack 5 can be lifted and lowered relative to the first base 52.
[0072] It can be understood that in order to realize the lifting and translation of the connecting assembly relative to the conveyor belt 4, a first base 52 and a first lifting assembly 53 are set. The first base 52 is a rigid structure, which can be a plate structure, a frame structure, a block structure, a groove structure, etc., as long as it can provide stable support for the first lifting assembly 53 and the connecting rack 5; the first lifting assembly 53 can include but is not limited to a rodless cylinder 531, and can include a guide column 56. The guide column 56 is vertically arranged on the first base 52, and the connecting rack 5 can be slidably connected to the guide column 56 through a slide rail, a guide rail, a pulley, a slide groove, and a slider; the number of the first lifting assemblies 53 can be designed and adjusted according to actual needs. For example, the width of the connecting rack 5 can be large, as shown in FIG. Figure 8 As shown, a guide post 56 is provided at each end of the docking frame 5 to ensure stable lifting. In this embodiment, the lifting and lowering of the first lifting component 53 can be controlled by utilizing its lifting limit or by utilizing the setting of a position sensor or electromagnetic switch in conjunction with the controller 2 for automatic control. For example, a rodless cylinder is selected based on the distance between the first base 52 and the upper surface of the conveyor belt 41, so that the lifting limit of the rodless cylinder is greater than the distance between the first base 52 and the upper surface of the conveyor belt 41. Then, when controlling the rodless cylinder, only the opening and closing command control is required; for another example, a position sensor or electromagnetic switch can be provided at the top of the guide post 56 to cooperate with the detection of the lifting of the rodless cylinder into position. In this embodiment, a frame 46 is designed; the frame 46 is a rigid frame structure, which can provide a stable installation position for the first drive motor 42, the synchronous belt 43, the synchronous wheel 44, and the shaft 45. In this embodiment, the shaft 45 and the conveyor belt 41 can be stably installed by cooperating with the column 47 and the guide plate 48. The guide plate 48 corresponds to the conveyor belt 41 one by one as the internal support of the conveyor belt 41. The conveyor belt 41 is sleeved outside the guide plate 48. The guide plate 48 stably supports the conveyor belt 41 to prevent the individual conveyor belt 41 from sinking. Or deformation leads to unstable transmission problem; the columns 47 are set at both ends of the guide plate 48 in a one-to-one correspondence with the guide plate 48, and the columns 47 serve as a connecting medium between the frame 46 and the guide plate 48. The frame 46, the columns 47 and the guide plate 48 can be integrally formed or connected by welding, bonding, clamping or other methods; accordingly, the shaft 45 can be connected to the side wall of the guide plate 48 or the side wall of the column 47 with a bearing to ensure the stable setting of the shaft 45, thereby realizing the spaced setting and synchronous driving of several conveyor belts 41.
[0073] Further, refer to the attached Figure 4In the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, the connecting assembly also includes a second base 57 and a second lifting assembly 58; the second base 57 is connected to the second end of the first lifting assembly 53; the first end of the second lifting assembly 58 is connected to the second base 57, and the second end of the second lifting assembly 58 is connected to the connecting rack 5, so that the connecting rack 5 can be raised and lowered relative to the second base 57.
[0074] It is understandable that in order to ensure the stability of the docking assembly, a second base 57 and a second lifting assembly 58 are provided at the second end of the first lifting assembly 53 in this embodiment, which reduces the difficulty of lifting the docking assembly into place in one go and reduces the risk of failure of the first lifting assembly 53 during long-distance lifting. At the same time, the depth of the docking slot 12 can only correspond to the lifting height of the second lifting assembly 58, and does not need to correspond to the entire lifting height of the docking assembly, which greatly reduces the depth of the docking slot 12 and reduces the difficulty and cost of preparation. The second base 57 is a rigid structure, which can be a plate structure, a frame structure, a block structure, a groove structure, etc. It can be the same as the first base 52 or different from the first base 52, as long as it can provide stable support for the second lifting assembly 58 and the docking rack 5; the second lifting assembly 58 can be, but is not limited to, a rodless cylinder, and can also be provided with a guide column 56 in conjunction with the first lifting assembly 53. The guide column 56 is vertically arranged on the second base 57, and the docking rack 5 can be slidably connected to the guide column 56 through a slide rail, a guide rail, a pulley, a slide groove, or a slider; the number of second lifting assemblies 56 can be designed and adjusted according to actual needs, for example: Figure 4 As shown, a second lifting assembly 56 is provided for each connector 51 to ensure stable lifting. Even if some of the second lifting assemblies 56 fail, the normal lifting of the glass sheet can still be guaranteed. Under this setting, the timing of starting the second lifting assembly 56 in this embodiment can be based on the control of the first lifting assembly 53 by the controller 2. For example, when the lifting height of the first lifting assembly 53 is set according to the limit, the controller 2 pre-stores the time when the first lifting assembly 53 is lifted. Then, when the controller 2 controls the first lifting assembly 53 to start lifting, it starts counting or counting down. After the time ends, it controls the second lifting assembly 56 to lift. The control of the second lifting assembly 56 to reach its full position can be controlled by using its lifting limit or by using the setting of a position sensor or electromagnetic switch in conjunction with the controller 2 for automatic control. This setting can refer to the setting method of the first lifting assembly 53 described above and will not be repeated here.
[0075] Furthermore, the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, also includes a first position sensor (not shown in the figure), a second position sensor (not shown in the figure) and a third position sensor (not shown in the figure); the first position sensor and the third position sensor are respectively arranged at the head and tail ends of the transmission component 4, and the second position sensor is arranged between the first position sensor and the third position sensor corresponding to the starting position of the docking component; the first position sensor is connected to the controller 2 signal, and is used to detect and send a feeding signal of the glass plate to the controller 2, and the controller 2 can control the transmission component 4 to start transmission according to the feeding signal; the second position sensor is used to detect and send a position signal of the glass plate relative to the docking component to the controller 2, and the controller 2 controls the transmission component 4 to stop transmission and synchronously controls the docking component to lift the glass plate according to the position signal of the glass plate relative to the docking component; the third position sensor is used to detect and generate a translation position signal of the docking component relative to the transmission component 4 to the controller 2, and the controller 2 controls the docking component to stop translation and drop the glass plate according to the translation position signal.
[0076] It is understandable that in order to achieve fully automatic and efficient control, a first position sensor, a second position sensor, and a third position sensor are provided in this embodiment. The three can be the same or different, and can be distance sensors, infrared sensors, electromagnetic switches, etc. Specifically, when the transfer vehicle carries the glass plate to the feeding end of the transfer component 4 or the glass plate is placed on the transfer component 4, the first position sensor detects the feeding signal and sends it to the controller 2, and the controller 2 starts the first drive motor 42 to run at a preset speed. When the connecting component is in the starting position of the translational action, the connecting part 41 does not extend out of the range of the transfer component 4. When the connecting component is in the end position of the translational action, the connecting part 41 extends out of the range of the transfer component 4 and all of its orthographic projections in the vertical direction fall within the range of the cutting base 1. The positions of the second position sensor and the third position sensor can be adjusted according to the size design of the transfer component 4 and the connecting part 51, and are not limited here. Specifically, when the glass plate is conveyed to the edge facing the cutting base 1 and passes the second position sensor, the second position sensor sends an in-position signal to the controller 2. At this time, the glass plate has not yet fully entered the supporting area of the docking assembly. When the edge of the glass plate passes the second position sensor away from the cutting base 1, the in-position signal from the second position sensor to the controller 2 disappears, indicating that the glass plate has fully entered the supporting area of the docking assembly. At this time, the controller 2 controls the first drive motor 42 of the transmission assembly 4 to stop running, and synchronously controls the docking assembly to lift upward so that the glass plate is separated from the conveyor belt 41, that is, higher than the transmission assembly 4, and then controls the docking assembly to translate toward the side of the cutting base 1. After the third position sensor detects that the docking assembly has translated into position, the controller 2 controls the docking assembly to stop the translation action, and at the same time controls the docking assembly to descend until the docking piece 41 falls into the docking groove 12, and the glass plate is supported by the supporting surface 11.
[0077] Further, refer to the attached Figure 4 In the ultra-thin glass cutting device provided in this embodiment, in a specific implementation, the connecting component also includes a second drive motor 54 and a drive screw 55; the drive screw 55 extends along the transmission direction of the transmission component 4, and the drive screw 55 is connected to the second drive motor 54 and the connecting member 51, so that when the second drive motor 54 drives the drive screw 55 to rotate, the connecting member 51 can reciprocate along the axial direction of the drive screw 55.
[0078] It can be understood that in order to enable the first base 52 to reciprocate on the frame 46 along the conveying direction of the conveyor belt 41, a second drive motor 54 and a drive screw 55 can be provided in this embodiment. The drive screw 55 is connected to the second drive motor 54 and the first base 52 at the same time. When the second drive motor 54 is started, the first base 52 can reciprocate along the axial direction of the drive screw 55, that is, the conveying direction of the conveyor belt 41. Of course, corresponding sliding matching structures can also be provided on the frame 46 and the first base 52, such as slide rails, guide rails, pulleys, slide grooves, sliders, etc.; at the same time, corresponding limit blocks (not shown in the figure) can also be provided on the frame to prevent the first base 52 from falling off when moving on the drive screw 55. It is not difficult to understand that in this embodiment, the second drive motor 54 is connected to the controller 2 signal. When the connecting assembly is controlled to lift upward so that the glass plate is separated from the conveyor belt 41, that is, higher than the transfer assembly 4, the second drive motor 54 is controlled to drive the first base 52 to translate toward the cutting base 1. After the third position sensor detects that the connecting assembly has been translated into place, the controller 2 controls the second drive motor 54 to stop the translation action.
[0079] It is not difficult to understand that the entire operation process of the ultra-thin glass cutting device provided in this embodiment is as follows:
[0080] After the first position sensor 53 is lifted into position, the controller 2 controls the second driving motor 54 to enable the first base 52 to drive the shuttle rack 5 to move horizontally along the driving screw 55 toward the cutting base 1, and the second driving motor 54 is controlled to stop. The synchronous wheel 44 and the conveyor belt 41 rotate around the shaft 51 to realize the transfer of the glass plate. When the glass plate is transferred to the second position sensor and continuously sends an in-position signal until the in-position signal disappears, the controller 2 can stop the first driving motor 42 and synchronously control the first lifting component 53 to lift the second base 57 and the shuttle rack 5. After the first lifting component 53 is lifted into position, the controller 2 controls the second lifting component 56 to lift the shuttle rack 5 so that the glass plate is higher than the conveyor belt 41 and is separated from the support of the conveyor belt 41. After the second lifting component 56 is lifted into position, the controller 2 controls the second driving motor 54 to enable the first base 52 to drive the shuttle rack 5 to move horizontally along the driving screw 55 toward the cutting base 1. The machine 54 drives the lead screw 55 in reverse so that the connecting frame 5 moves in the direction of the transmission component 4 and leaves the cutting base 1 area, waiting for the cutting to be completed. In this process, the third position sensor and the second position sensor can be used in reverse, which will not be described in detail here. The controller 2 connected to the laser emission component 3 will send a control instruction based on the feedback of the second position sensor to enable the laser emission component 3 to cut the glass plate according to the formula (1) to (3) described in Example 1. After the cutting is completed, the controller 2 controls the second drive motor 54 to start so that the connecting frame 5 moves in the direction of the cutting base 1 and the connecting member 51 is inserted into the connecting groove 12. Then, the controller 2 drives the second lifting component 56 to lift the cut glass plate away from the supporting surface 11 and supported by the connecting frame 5. Then, the connecting frame 5 is translated in reverse so that the glass plate returns to the side of the transmission component 4. Then, the second lifting component 56 and the first lifting component 53 are driven in reverse so that the glass plate is supported by the conveyor belt 41 again. Then, the first drive motor 42 is driven in reverse to drive the synchronous wheel to transfer the glass plate in reverse, completing the entire transfer and cutting process.
