[0041] The present application has the following beneficial effects:

[0042] First, the double-valve double-gantry high-precision five-axis dispensing machine provided by the present application, in specific implementation, since the present application is provided with the two aforementioned forward and backward moving components, the two aforementioned multi-directionally adjustable workpiece carriers and the two aforementioned dispensing devices, thus, the two aforementioned two-dimensional moving components A are used to correspondingly control the two aforementioned dispensing devices to move left and right and up and down to the desired positions respectively, thereby synchronously dispensing the parts of the surfaces of the two placed workpieces that require dispensing.

[0101] The following describes in detail a double-valve double-gantry high-precision five-axis dispensing machine 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0102] Reference Figures 1 to 9 As shown;

[0103] The double-valve double-gantry high-precision five-axis dispensing machine 1000 provided in accordance with an embodiment of the present invention includes a chassis 10 and further includes:

[0104] The front and rear moving member 20 is provided with two front and rear moving members 20, and is fixed on the upper end surface of the chassis 10 in parallel along the front and rear direction;

[0105] Multi-directionally adjustable workpiece carrier 30; two multi-directionally adjustable workpiece carriers 30 are provided and fixedly mounted on the two forward and backward moving members 20 respectively so as to be able to move forward and backward respectively under the control of the two forward and backward moving members 20;

[0106] Gantry bracket 40; the gantry bracket 40 is mounted on the chassis 10, and two are provided from left to right to correspond to being located above the two front and rear moving members 20;

[0107] Two-dimensional moving member A50; two two-dimensional moving members A50 are provided, and are fixedly mounted on the upper front portion of the two gantry brackets 40;

[0108] Glue dispensing device 60; two glue dispensing devices 60 are provided, one of which is fixed at the bottom of the two-dimensional movable component A50 on the left side, so that it can move synchronously left and right, up and down under the control of the two-dimensional movable component A50 on the left side; the other glue dispensing device 60 is fixed at the bottom of the two-dimensional movable component A50 on the right side, so that it can move synchronously left and right, up and down under the control of the two-dimensional movable component A50 on the right side.

[0109] Based on the above, it can be clearly seen that when this application is implemented, it is mainly used as a double-valve double-gantry high-precision five-axis dispensing machine 1000.

[0110] Specifically, when applying this application, assemble this application according to the above-mentioned structure, and place the two workpieces that need to be glued on the two multi-directional adjustable workpiece carriers 30 respectively. Then, the two glue dispensing devices 60 can be used to separately perform glue dispensing on the parts of the surfaces of the two placed workpieces that need to be glued.

[0111] During the specific dispensing process, the two multi-directionally adjustable workpiece carriers 30 can be moved forward and backward to the desired position under the control of the two forward and backward moving components 20, and the two multi-directionally adjustable workpiece carriers 30 can obviously be adjusted in multiple directions so that the storage angle of the workpiece loaded thereon can be adjusted, such as swinging it so that a certain dispensing part of its side wall is facing upward, and then, the corresponding two-dimensional moving component A50 can be used to control the corresponding dispensing device 60 to move left and right and up and down to the desired position, so as to perform dispensing on different dispensing parts on the surface of the corresponding workpiece whose storage angle can be changed in multiple directions, such as dispensing on multiple dispensing parts that are not in the same plane, such as the upper end face and side wall of the corresponding workpiece, regardless of front and back.

[0112] Obviously, the application of the above-mentioned present application will have the following technical effects:

[0113] On the one hand, since the present application is provided with the two aforementioned forward and backward moving components 20, the two aforementioned multi-directionally adjustable workpiece carriers 30 and the two aforementioned dispensing devices 60, the two aforementioned two-dimensional moving components A50 are used to correspondingly control the two aforementioned dispensing devices 60 to move left and right and up and down to the desired positions respectively, and the parts of the surfaces of the two placed workpieces that require dispensing can be dispensed synchronously. Compared with the traditional single dispensing machine that can only dispense glue on a single workpiece, the present application can greatly improve the efficiency of the dispensing operation and greatly shorten the workpiece processing cycle.

[0114] On the other hand, since the two multi-directionally adjustable workpiece carriers 30 can be moved forward and backward to the desired positions respectively under the control of the two front and rear moving components 20, and the two multi-directionally adjustable workpiece carriers 30 themselves can be adjusted in multiple directions, the front and rear placement positions and the placement angles of the workpieces loaded thereon can be adjusted. For example, if it is swung so that a certain spot gluing part of its side wall faces upward, it is convenient to use the corresponding two-dimensional moving component A50 to control the corresponding spot gluing device 60 to move left and right and up and down to the desired position to perform spot gluing on different spot gluing parts such as the corresponding workpiece side wall whose placement angle can be changed in multiple directions. In this way, the present application is very flexible to use and has strong adaptability. It can use a single spot gluing machine to perform flexible spot gluing on multiple spot gluing positions on the surfaces of two workpieces that are not in the same plane at the same time.

[0115] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0116] Furthermore, in specific implementation, Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the dispensing device 60 includes a CCD shooting component 601 for photographing and locating the dispensing portion on the surface of the workpiece and a dispensing component 602 for dispensing the dispensing portion on the surface of the workpiece.

[0117] Among them, the dispensing component 602 includes a glue barrel 6021 for installing glue, a dispensing valve 6022 and a dispensing needle 6023; the glue discharge end of the glue barrel 6021 is detachably connected to the glue feed end of the dispensing valve 6022; the dispensing needle 6023 is vertically fixed to the bottom of the dispensing valve 6022, and is detachably connected to the glue discharge end of the dispensing valve 6022, and the height of the bottom of the dispensing needle 6023 is lower than the height of the bottom of the CCD shooting component 601.

[0118] In this regard, it is clear that for any of the dispensing devices 60, the corresponding two-dimensional moving component A50 is used to control the CCD shooting component 601 and the dispensing component 602 to move synchronously left and right and up and down to the required positions, so that the different dispensing locations on the surface of the workpiece loaded on the corresponding multi-directional adjustable workpiece carrier 30 can be positioned and dispensed, so that the dispensing position will be very accurate and reliable.

[0119] In addition, the dispensing valve 6022 is preferably the utility model patent "Dispensing Piezoelectric Valve" as described in the patent number "202322984548.1" previously applied for by the applicant of this patent, or other types of piezoelectric ceramic dispensing valves previously applied for by the applicant of this patent, etc., which are common in the prior art, so the details thereof will not be elaborated here.

[0120] In this way, under the control of the dispensing valve 6022, the glue liquid introduced from the glue barrel 6021 can be sprayed out through the dispensing needle 6023 at a set frequency to perform positioning dispensing on the surface of the workpiece that needs dispensing.

[0121] And in this technical solution, the control Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the multi-directional adjustable workpiece carrier 30 includes a U-shaped bracket 301, a rotating plate 302, a driving member A303, a driving member B304 and a workpiece carrying platform 305;

[0122] Among them, the U-shaped bracket 301 is fixed on the front and rear moving components 20 at the corresponding position; the rotating plate 302 is clamped in the U-shaped bracket 301, and its front end is rotatably connected to the front of the U-shaped bracket 301, and its rear end is rotatably connected to the rear of the U-shaped bracket 301; the driving component A303 is fixed at the rear of the U-shaped bracket 301, and its front end rotating shaft is connected to the rear end of the rotating plate 302; the driving component B304 is fixed on the upper end surface of the rotating plate 302; the bottom of the workpiece supporting platform 305 is connected to the upper end rotating shaft of the driving component A303.

[0123] In this way, under the control of the driving component A303, the rotating plate 302 can be driven to drive the driving component B304 and the workpiece carrier 305 to rotate left and right, and under the control of the driving component B304, the workpiece carrier 305 can be driven to rotate circumferentially. Therefore, under the joint action of the driving component A303 and the driving component B304, the workpiece carrier 305 can be adjusted in multiple directions, so that the placement angle of the workpiece loaded thereon can be adjusted in multiple directions.

[0124] Furthermore, when the front and rear placement positions and the placement angles of the workpiece loaded on the workpiece carrier 305 are adjustable, it can indeed be swung so that a certain glue spot on its side wall or other position faces upward, so as to facilitate the use of the two-dimensional moving component A50 to control the corresponding position of the CCD shooting component 601 and the glue spotting component 602 to move left and right and up and down to the required position synchronously to position and glue different glue spotting positions such as the side wall of the workpiece whose placement angle can be changed in multiple directions, so that the present application is indeed very flexible to use and has strong adaptability.

[0125] It should be noted here that, in a preferred embodiment, the driving component A303 and the driving component B304 are preferably driving motors or rotary cylinders commonly used in the prior art.

[0126] Preferably, in this technical solution, the control Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, a workpiece supporting position 3051 is provided in the middle of the upper end surface of the workpiece supporting platform 305, and the workpiece supporting position 3051 is provided with a vacuum suction nozzle 3052 for adsorbing the workpiece, and a negative pressure suction component connected to the vacuum suction nozzle 3052 is provided inside the workpiece supporting plate.

[0127] In this way, under the negative pressure suction action of the negative pressure suction component, the multiple vacuum suction nozzles 3052 can be used to negatively adsorb the workpiece placed on the workpiece supporting position 3051, so that the placed workpiece is placed firmly and not easy to fall.

[0128] And in the preferred embodiment, continue to control Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the front portion of the U-shaped bracket 301 is provided with a front rotating bearing 306, the rear portion of the U-shaped bracket 301 is provided with a rear rotating bearing 307, the front end of the rotating plate 302 is coaxially connected to the rear portion of the front rotating bearing 306, and the rear end is coaxially connected to the front portion of the rear rotating bearing 307, and the front end rotating shaft of the driving component A303 is coaxially connected to the rear portion of the rear rotating bearing 307. In this way, the rotating plate 302 is supported and fixed, and can also be rotated left and right under the control of the driving component A303.

[0129] Furthermore, in the specific implementation, Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the two-dimensional moving component A50 includes a left-right moving component A501 and an up-down moving component A502;

[0130] Among them, the left-right moving component A501 is fixed along the left-right direction at the upper front part of the gantry bracket 40 at the corresponding position; the up-down moving component A502 is fixed vertically on the left-right moving component A501, so that it can move left-right under the control of the left-right moving component A501; the CCD shooting component 601 and the dispensing component 602 are both fixed at the bottom of the up-down moving component A502 at the corresponding position, so that they can move up and down synchronously under the control of the up-down moving component A502 at the corresponding position.

[0131] Therefore, under the control of the left and right moving component A501, the up and down moving component A502 at the corresponding position can be driven to drive the CCD shooting component 601 and the glue dispensing component 602 at the corresponding position to move left and right, and under the control of the up and down moving component A502, the CCD shooting component 601 and the glue dispensing component 602 at the corresponding position can be driven to move up and down.

[0132] Furthermore, under the joint action of the left-right moving component A501 and the up-down moving component A502, the CCD shooting component 601 and the glue dispensing component 602 at the corresponding position can move left-right and up-down to position and dispense glue on different glue dispensing parts such as the side wall of the workpiece on the corresponding position of the workpiece supporting platform 305 whose placement angle can be changed in multiple directions.

[0133] It should be noted here that, in a preferred embodiment, the left-right moving member A501 and the up-down moving member A502 are preferably screw-driven linear modules, cylinder-driven linear modules or pulley-driven linear modules commonly used in the prior art.

[0134] In addition, in this technical solution, continue to control Figure 5 and Figure 6As shown, according to one embodiment of the present invention, the present application further includes an up and down moving component B70 and a UV lamp curing component 80:

[0135] Among them, there are two up and down moving components B70, which are fixed on the upper rear part of the two gantry brackets 40 and are located directly above the two front and rear moving components 20; there are two UV lamp curing components 80, which are fixed on the bottom of the two up and down moving components B70, so that they can move up and down respectively under the control of the two up and down moving components B70.

[0136] Therefore, under the control of the two up and down moving components B70, the two UV lamp curing components 80 can be driven to move up and down to appropriate positions to bake the glue-dotting parts on the surface of the workpiece loaded on the two workpiece supporting platforms 305 that move forward and backward to the bottom thereof, so that the glue-dotting liquid is UV-cured.

[0137] Furthermore, by adding the two vertical moving components B70 and the two UV lamp curing components 80, the present application also has a dual-workpiece dispensing and curing function, resulting in a better use effect.

[0138] It should be noted here that, in a preferred embodiment, the up and down moving member B70 is also preferably a screw drive linear module, a cylinder drive linear module or a pulley drive linear module commonly used in the prior art.

[0139] Furthermore, in the specific implementation, Figure 1 、 Figure 2 and Figure 7 As shown, according to one embodiment of the present invention, the present application further includes a glue clearing component 90;

[0140] Among them, the glue cleaning component 90 is fixed on the upper end surface of the chassis 10, and two are provided, and are correspondingly located beside the two front and rear moving components 20, for cleaning the residual glue flowing out from the lower ends of the two dispensing needles 6023.

[0141] Therefore, by adding the two glue cleaning components 90, the present application also has the function of cleaning the residual glue at the lower end of the dispensing needle 6023, so that the two dispensing needles 6023 can be reused many times to extend their service life, thereby making the overall use effect of the present application better.

[0142] Again, in this technical solution, according to one embodiment of the present invention, the glue cleaning component 90 preferably includes a glue dispensing needle wiping component 901 and a residual glue collecting box 902 that are arranged closely together;

[0143] The dispensing needle wiping component 901 and the upper portion of the residual glue collection box 902 are both open, and the dispensing needle wiping component 901 is provided with a cleaning brush 9011 pre-installed with cleaning liquid inside, and a driving component C9012 is provided outside to drive the cleaning brush 9011 to rotate.

[0144] Therefore, when the present application is used in a specific manner, the two dispensing needles 6023 are driven to move downward and extend into the two residual glue collection boxes 902 under the control of the two two-dimensional moving components A50, so that the residual glue flowing out from the lower ends thereof can be collected by the two residual glue collection boxes 902, and then the two dispensing needles 6023 are driven to move downward and extend into the interior of the two dispensing needle wiping components 901 under the control of the two two-dimensional moving components A50, so that the two cleaning brushes 9011 soaked in cleaning liquid can be driven to rotate by the two rotating components C9012 to wipe and clean the lower ends of the two dispensing needles 6023. In this way, the two dispensing needles 6023 that have been cleaned can be reused later.

[0145] Moreover, when the glue cleaning component 90 includes the glue dispensing needle wiping component 901, it is preferably the invention patent "Glue Dispensing Needle Cleaning Device" as described in patent number "202310528148.1" previously applied by the applicant of this patent, or other types of glue dispensing needle cleaning devices previously applied by the applicant of this patent, etc., which are common in the prior art, so the details thereof will not be elaborated here.

[0146] It should be added that, in the specific implementation, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the present application further includes a dispensing needle calibration component 100 for correcting the left-right direction and the front-back direction of the dispensing needle 6023;

[0147] There are two dispensing needle calibration components 100 , which are fixed on the front end or the rear end of the two U-shaped brackets 301 .

[0148] Therefore, each time the dispensing needle 6023 is replaced, the left and right position and the front and back position of the needle head will have a certain deviation compared to the calibrated standard position. The present application sets the two dispensing needle calibration components 100, which can correct and calibrate the left and right directions and the front and back directions of the two replaced dispensing needles 6023. When the present application is used again in the future, the dispensing position of the part of the workpiece surface that needs to be dispensed after the dispensing needle 6023 needle head is corrected and calibrated can still be kept accurate, so that the overall reliability of the present application can be optimized.

[0149] It is further necessary to add that, in the specific implementation, continue to compare Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the dispensing needle calibration component 100 includes:

[0150] A calibration seat 1001, wherein a positioning groove 1002 is downwardly formed on the upper end surface of the calibration seat 1001, and the positioning groove 1002 comprises a first through groove 1003 extending along the left-right direction and penetrating the outer wall of the left end of the calibration seat 1001, and a second through groove 1004 extending along the front-back direction and penetrating the outer wall of the rear end of the calibration seat 1001;

[0151] A left-right direction calibration mechanism includes a first transmitting sensor 1005 and a first receiving sensor 1006. The first transmitting sensor 1005 and the first receiving sensor 1006 are arranged on the left and right inner walls of the positioning groove 1002 opposite to each other in the left-right direction. The first receiving sensor 1006 is used to receive the first positioning light emitted by the first transmitting sensor 1005 to calibrate the left-right direction coordinates of the needle head of the dispensing needle 6023.

[0152] A front-to-back direction calibration mechanism, comprising a second transmitting sensor 1007 and a second receiving sensor 1008, the second transmitting sensor 1007 and the second receiving sensor 1008 being arranged on the front and rear inner walls of the positioning groove 1002 opposite to each other along the front-to-back direction, the second receiving sensor 1008 being used to receive the second positioning light emitted by the second transmitting sensor 1007 to calibrate the front-to-back direction coordinates of the needle head of the dispensing needle 6023;

[0153] The first transmitting sensor 1005 , the first receiving sensor 1006 , the second transmitting sensor 1007 and the second receiving sensor 1008 are located in the same horizontal plane, and the light emitted by the first transmitting sensor 1005 and the second transmitting sensor 1007 intersect in the positioning groove 1002 .

[0154] In a preferred embodiment, the first emission sensor 1005 and the second emission sensor 1007 are both infrared generators or laser generators.

[0155] Based on the above, it is clear that the operating method for the correction and calibration of the dispensing needle 6023 in this application is mainly as follows:

[0156] Step 1: Control the dispensing needle 6023 to move left and right, up and down by the two-dimensional moving member A50 until the needle tip of the dispensing needle 6023 is located outside the first through slot 1003 or outside the second through slot 1004;

[0157] In the second step, the two-dimensional moving member A50 is used to control the dispensing needle 6023 to move rightward, so that the dispensing needle 6023 actively moves through the first through slot 1003 and laterally into the positioning slot 1002, or the front-back moving member 20 is used to control the dispensing needle calibration member to move backward, so that the dispensing needle 6023 passively moves through the second through slot 1004 and laterally into the positioning slot 1002;

[0158] Step 3: When the dispensing needle 6023 moves to between the first transmitting sensor 1005 and the first receiving sensor 1006 to block the first positioning light, the left and right coordinates of the dispensing needle 6023 can be corrected.

[0159] Step 4. Then, the dispensing needle 6023 is controlled to move left and right through the two-dimensional moving component A50. When the needle head of the dispensing needle 6023 moves between the second transmitting sensor 1007 and the second receiving sensor 1008 to block the second positioning light, the front and rear direction coordinates of the needle head of the dispensing needle 6023 can be corrected at this time.

[0160] It should be noted here that, during the above-mentioned related operations, it is necessary that when the needle head of the dispensing needle 6023 is located in the positioning groove 1002, its lower end needs to be lower than the horizontal plane where the first transmitting sensor 1005, the first receiving sensor 1006, the second transmitting sensor 1007 and the second receiving sensor 1008 are located, so that it can be moved to the desired position to block the first positioning light and / or the second positioning light.

[0161] Therefore, when the dispensing needle 6023 is replaced, or when the left-right coordinates and the front-back coordinates of the glue outlet at its lower end point deviate due to skew during use, the dispensing needle calibration component 100 described in the present application can be used to correct the left-right coordinates and the front-back coordinates, so that its service life can be further extended, so that the present application can indeed achieve accurate and reliable dispensing of glue on the parts of the workpiece surface that need dispensing.

[0162] Other embodiments and the like are not described here as examples.

[0163] To sum up, the double-valve double-gantry high-precision five-axis dispensing machine 1000 provided by the present application, during specific implementation, since the present application is provided with the two aforementioned forward and backward moving components 20, the two aforementioned multi-directionally adjustable workpiece carriers 30 and the two aforementioned dispensing devices 60, thus, the two aforementioned two-dimensional moving components A50 are used to correspondingly control the two aforementioned dispensing devices 60 to move left and right and up and down to the desired positions respectively, thereby synchronously dispensing the parts of the surfaces of the two placed workpieces that require dispensing. Compared with the traditional single dispensing machine that can only dispense glue on a single workpiece, the present application can greatly improve the efficiency of the dispensing operation and greatly shorten the workpiece processing cycle.

[0164] Moreover, since the two multi-directionally adjustable workpiece carriers 30 can be moved forward and backward to the desired positions respectively under the control of the two front and rear moving components 20, and the two multi-directionally adjustable workpiece carriers 30 themselves can be adjusted in multiple directions, the front and rear placement positions and the placement angles of the workpieces loaded thereon can be adjusted. For example, by swinging it so that a certain gluing part of its side wall faces upward, it is convenient to use the corresponding two-dimensional moving component A50 to control the corresponding gluing device 60 to move left and right and up and down to the desired position to perform gluing on different gluing parts such as the corresponding workpiece side wall whose placement angle can be changed in multiple directions. In this way, the present application is very flexible to use and has strong adaptability, and can use a single gluing machine to perform flexible gluing on multiple gluing positions on the surfaces of two workpieces that are not in the same plane at the same time.

[0165] In addition, by adding the two UV lamp curing components 80, the present application also has a dispensing curing function, which makes the use effect better. By adding the two glue cleaning components 90, the present application also has a glue cleaning function for the residual glue at the lower end of the dispensing needle 6023, so that the dispensing needle 6023 can be reused many times to extend its service life, so that the overall use effect of the present application is better. By adding the two dispensing needle calibration components 100, the left and right coordinates and the front and back coordinates of the needle heads of the two dispensing needles 6023 can be corrected respectively, so that the service life of the two dispensing needles 6023 can be further extended, so that the present application can indeed achieve accurate and reliable dispensing of glue on the parts of the workpiece surface that need to be glued.

[0166] Furthermore, the double-valve double-gantry high-precision five-axis dispensing machine 1000 provided by this application is indeed extremely practical and has excellent performance, which makes this application bound to have great market promotion value. This application will also be very popular and will surely be effectively popularized.
