Description

Technical Field

[0001] The present application relates to the field of glue dispensing equipment, and in particular to a five-axis glue dispensing machine. Background Art

[0002] Currently, most of the dispensing machines on the market are XYZ three-axis dispensing machines. Although this type of dispensing machine has achieved automation of some processes, it has poor adaptability to the dispensing workpiece. A single step can only complete the dispensing of flat surfaces or simple spatial curves. Not only does it greatly reduce production efficiency and dispensing efficiency, it also increases labor costs and inaccurate positioning. Therefore, when it is necessary to dispense relatively complex products, a five-axis dispensing machine is usually used for precision dispensing.

[0003] A general five-axis dispensing machine adopts an X-axis left-right moving mechanism, a Z-axis up-and-down moving mechanism, an RX-axis rotation mechanism, an RZ-axis rotation mechanism, a visual system, a dispensing mechanism, and a Y-axis forward-and-backward moving mechanism. The Y-axis forward-and-backward moving mechanism is movably arranged below the Z-axis up-and-down moving mechanism, and the Y-axis forward-and-backward moving mechanism is connected to a tooling fixture to solve the above problems. However, since multiple azimuth movements and rotational jitters are required, it is easy for the glue dots on the product after dispensing to fail to completely solidify and flow, resulting in poor dispensing effects. Summary of the invention

[0004] In order to improve the above-mentioned problems, the present application provides a five-axis dispensing machine.

[0005] The five-axis dispensing machine provided in this application adopts the following technical solution: A five-axis glue dispensing machine comprises a glue dispensing base, a glue dispensing frame, an X-axis moving component, a Z-axis moving component, an RU rotating component, a Y-axis moving component and a glue dispensing component; the glue dispensing frame and the Y-axis moving component are installed on the glue dispensing base; the X-axis moving component is installed on the glue dispensing frame, and the Z-axis moving component is connected to the moving end of the X-axis moving component; the RU rotating component is connected to the moving end of the Y-axis moving component, and the product is installed on the RU rotating component; the glue dispensing component is connected to the moving end of the Z-axis moving component; the glue dispensing component comprises a glue dispensing cylinder, a glue dispensing head, a visual detection structure and a curing structure; the glue dispensing cylinder provides storage and transportation of glue dispensing materials and is connected to the moving end of the Z-axis moving component; the glue dispensing head is connected to the glue dispensing cylinder; the curing structure is installed on the outer wall of the glue dispensing head and provides glue dispensing curing; the visual detection structure is connected to the curing structure to provide identification of glue dispensing trajectory and positioning.

[0006] By adopting the above technical solution, the X-axis moving component and the Z-axis moving component are used to drive the dispensing component to move horizontally and vertically, and the front and rear positions and rotation angles of the product are changed by the Y-axis moving component and the RU rotating component, so that the product can be dispensed in all directions to ensure the accuracy of the dispensing position. During the dispensing process, the dispensing trajectory is identified and positioned by the visual detection structure, so that the dispensing position can be identified and positioned when the dispensing position required for the product is constantly changing, and then the dispensing material is transported to the dispensing head by the dispensing cylinder, and the dispensing material is dispensed to the product surface by the dispensing head. The curing structure is used to allow the dispensing head to continuously dispense glue while curing the dispensing material on the product surface, thereby ensuring the stability of the dispensing and avoiding the flow of the dispensing material during rotation or movement.

[0007] Optionally, the curing structure includes a focusing ring and a plurality of curing lamp heads; the plurality of curing lamp heads provide UV light rays that are condensed into straight lines, and the curing lamp heads are arranged in the focusing ring, and the plurality of UV light rays are irradiated toward the dispensing head.

[0008] By adopting the above technical solution, the dispensing head moves up and down with the Z-axis moving component to dispense glue to the product, and uses a focusing ring and several curing lamp heads to irradiate several UV rays. When the product is dispensed, the UV rays can cure the dispensing material on the surface. At the same time, the UV rays are concentrated in the form of light to avoid scattered irradiation and increase the irradiation flux. In addition, multiple UV rays can irradiate the product at the same time, which can improve the curing efficiency and further accelerate the curing speed.

[0009] Optionally, the plurality of curing lamp heads are tilted in the focusing ring so that when the plurality of UV rays are irradiated toward the dispensing head, all the UV rays converge into a point below the dispensing head.

[0010] By adopting the above technical solution, the point where the UV light converges is located below the dispensing head, so that the UV light does not contact the dispensing head. When the dispensing head dispenses glue on the product, the UV light will not irradiate the dispensing head, thereby preventing the UV light from curing the glue outlet point of the dispensing head and causing blockage of the dispensing head.

[0011] Optionally, an installation cavity is opened in the focusing ring, and a plurality of irradiation ports are opened in the installation cavity, and the curing lamp head corresponds to the irradiation ports one by one; the curing lamp head is located in the installation cavity, and the irradiation direction is toward the irradiation port; the curing structure is also connected to an adjustment structure, and the adjustment structure is connected to the curing lamp head, and the adjustment end is located at the dispensing head.

[0012] By adopting the above technical solution, the curing lamp head is located in the installation cavity, and the inclination angle of the curing lamp head can be adjusted by using the adjustment structure, so as to adapt to the dispensing positions of different dispensing heads or different products.

[0013] Optionally, the adjustment structure includes an articulated frame, a reset part, an adjustment part and a drive part; the curing lamp head is hinged to the articulated frame; one end of the reset part is connected to the wall of the installation cavity, and the other end is connected to the curing lamp head; the adjustment part is connected to the curing lamp head and passes through the focusing ring to extend outward from the installation cavity; the drive part is connected to the outer wall of the dispensing head, and is connected to the side of the adjustment part away from the focusing ring.

[0014] By adopting the above technical solution, the driving part uniformly lifts and lowers all the adjustment parts along the extension direction of the dispensing head. During the lifting process, all the adjustment parts synchronously adjust the inclination angle of the curing lamp head along the articulated frame to adapt to different dispensing heads or dispensing products. At the same time, when the dispensing head rises and no longer dispenses glue, the inclination angle of the curing lamp head can be adjusted to continue irradiating the dispensing material, thereby extending the irradiation time and improving the curing efficiency.

[0015] Optionally, a heat insulation frame is further provided on the outer wall of the dispensing head, and the driving unit is installed on the heat insulation frame.

[0016] By adopting the above technical solution, the heat is blocked by the heat insulation frame to ensure the stable driving of the driving part and extend the service life of the driving part.

[0017] Optionally, a guide opening is provided on a side of the focusing ring away from the resetting portion, and the adjusting portion passes through the guide opening and extends toward the driving portion.

[0018] By adopting the above technical solution, the guide opening provides the limiting and guiding functions for the adjusting part, thereby preventing the position of the adjusting part from being offset and avoiding the situation where the irradiation angle of any curing lamp head is inconsistent.

[0019] Optionally, the outer wall of the focusing ring is further provided with a sensing part, the sensing part is electrically connected to an external controller, and the sensing end of the sensing part is consistent with the direction of the dispensing head.

[0020] By adopting the above technical solution, the sensing part can measure the rising distance of the dispensing head in real time, and then the controller can calculate the distance data and send control instructions to the driving part, so that the convergence point of the curing lamp head can always irradiate the dispensing material, thereby extending the irradiation time.

[0021] Optionally, the focusing ring is further provided with a reflector in a direction away from the irradiation port, and the mirror surface is uneven to provide diffuse reflection of the UV light.

[0022] By adopting the above technical solution, when the driving part irradiates all the curing lamp heads toward the reflector through the adjusting part, all UV rays are diffusely reflected, so that the focusing ring scatters all the diffusely reflected UV rays toward the product, thereby expanding the irradiation area.

[0023] Optionally, the reflector has an inverted triangle mirror structure.

[0024] By adopting the above technical solution, the reflector has an inverted triangle mirror structure, which can repeatedly reflect UV light. At the same time, combined with the uneven mirror surface, the diffuse reflection is wider.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use the X-axis moving component and the Z-axis moving component to drive the dispensing component to move horizontally and vertically, and use the Y-axis moving component and the RU rotating component to change the front and rear position and rotation angle of the product, so that the product can be dispensed in all directions to ensure the accuracy of the dispensing position. During the dispensing process, the dispensing trajectory is identified and located by the visual detection structure, so that the dispensing position can be identified and located when the dispensing position required by the product is constantly changing. The dispensing cylinder then transports the dispensing material to the dispensing head, and the dispensing material is dispensed to the product surface through the dispensing head. The curing structure allows the dispensing head to continuously dispense while curing the dispensing material on the product surface, thereby ensuring the stability of the dispensing and preventing the dispensing material from flowing during rotation or movement. 2. When the dispensing head moves up and down with the Z-axis moving component to dispense the product, a focusing ring and several curing lamp heads are used to irradiate several UV rays. When the product is dispensed, the UV rays can cure the dispensing materials on the surface. At the same time, the form of converging into light can avoid the scattered irradiation of UV rays and increase the irradiation flux. Multiple UV rays can irradiate the product at the same time, which can improve the curing efficiency and further speed up the curing speed. 3. The point where the UV light converges is located below the dispensing head, so that the UV light does not contact the dispensing head. When the dispensing head dispenses glue on the product, the UV light will not irradiate the dispensing head, thus preventing the UV light from curing the dispensing point of the dispensing head and causing the dispensing head to be blocked; 4. The curing lamp head is located in the installation cavity, and the adjustment structure can be used to adjust the inclination angle of the curing lamp head, so as to adapt to the dispensing positions of different dispensing heads or different products.

[0032] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0033] The embodiment of the present application discloses a five-axis dispensing machine.

[0034] A five-axis dispensing machine, reference Figure 1 As shown, it includes a dispensing base 1, a dispensing frame 2, an X-axis moving component 3, a Z-axis moving component 4, an RU rotating component 5, a Y-axis moving component 6 and a dispensing component 7; the dispensing frame 2 and the Y-axis moving component 6 are installed on the dispensing base 1, the X-axis moving component 3 is installed on the dispensing frame 2, the X-axis moving component 3 and the Y-axis moving component 6 are used to provide dispensing position adjustment in the front, back, left and right directions during the dispensing process, and the Z-axis moving component 4 is connected to the moving end of the X-axis moving component 3, so that the Z-axis moving component 4 can be driven by the moving end of the X-axis moving component 3 to move horizontally along the dispensing frame 2, and the moving end of the Z-axis moving component 4 can provide lifting and lowering in the vertical direction.

[0035] The RU rotating component 5 is connected to the moving end of the Y-axis moving component 6. The product is installed on the RU rotating component 5. The RU rotating component 5 provides R-axis and U-axis rotation. The Y-axis moving component 6 can drive the RU rotating component 5 to move forward and backward along the dispensing base 1. The rotating end of the RU rotating component 5 is provided with a clamping part for product installation and connection, such as a mechanical claw or a clamp. After the product is fixed by the mechanical claw or the clamp, the RU rotating component 5 can drive the product to rotate along the R-axis and the U-axis to adjust the dispensing position of the product.

[0036] The glue dispensing component 7 is connected to the moving end of the Z-axis moving component 4. The glue dispensing component 7 is used for glue dispensing the product. The glue dispensing component 7 is lifted and lowered in the vertical direction through the moving end of the Z-axis moving component 4, and cooperates with the Z-axis moving component 4 to be moved in the horizontal direction of the glue dispensing base 1 by the X-axis moving component 3, that is, moving left and right, so that the glue dispensing component 7 can change its horizontal position and provide lifting and lowering through the Z-axis moving component 4 to achieve glue dispensing on the product. The product is driven by the Y-axis moving component 6 and the RU rotating component 5 to move along the front and rear directions of the glue dispensing base 1 and rotate along the rotation direction, thereby changing the glue dispensing position of the product to achieve the effect of five-axis glue dispensing and ensure the accuracy and completeness of the glue dispensing position.

[0037] Among them, the Y-axis moving component 6 and the X-axis moving component 3 can both be driven by chains, the Z-axis moving component 4 can be driven by screw rods or cylinders, and the RU-axis rotating component can be driven by a motor and a rotating shaft.

[0038] Among them, reference Figure 2 As shown, the glue dispensing assembly 7 includes a glue dispensing cylinder 71, a glue dispensing head 72, a visual detection structure 73 and a curing structure 74. The glue dispensing cylinder 71 provides storage and transportation for glue dispensing materials. A small delivery pump or an external pressure structure can be provided on the glue dispensing cylinder 71 to provide sufficient pressure for glue dispensing.

[0039] The glue dispensing cylinder 71 is connected to the moving end of the Z-axis moving component 4, and the glue dispensing head 72 is connected to the glue dispensing cylinder 71, so that the glue dispensing head 72 and the glue dispensing cylinder 71 can be lifted and moved through the moving end of the Z-axis moving component 4. The glue dispensing head 72 includes a heated piezoelectric spray valve, which can heat and soften the glue dispensing material and increase the glue dispensing pressure at the same time. The curing structure 74 is installed on the outer wall of the glue dispensing head 72 and provides glue dispensing curing. The curing structure 74 can be cured by UV light. The UV light curing allows the glue dispensing head 72 to irradiate the glue dispensing location while dispensing UV light, so that the glue dispensing material is quickly cured to avoid the glue dispensing material from falling or flowing before it is completely solidified during the movement or rotation of the product.

[0040] The visual detection structure 73 is connected to the curing structure 74 to provide identification of the dispensing trajectory and positioning. The visual detection structure 73 can adopt a CCD identification and positioning system, including a CCD identification camera. The CCD identification and positioning system is electrically connected to an external controller 8. The electrical connection can be an electrical signal connection with the ability to receive and send signals. The external controller 8 uses the CCD identification and positioning system to locate the position of the dispensing position required for the product, and issues control instructions to control the dispensing component 7 to accurately dispense the product.

[0041] Specifically, the X-axis moving component 3 and the Z-axis moving component 4 are used to drive the glue dispensing component 7 to move horizontally and vertically, and the Y-axis moving component 6 and the RU rotating component 5 are used to change the front and rear position and the rotation angle of the product, so that the product can be glued in all directions to ensure the accuracy of the glue dispensing position. During the glue dispensing process, the glue dispensing trajectory is identified and positioned by the visual detection structure 73, so that the glue dispensing position can be identified and positioned when the glue dispensing position required for the product is constantly changing, and then the glue dispensing cylinder 71 transports the glue dispensing material to the glue dispensing head 72, and the glue dispensing material is dispensed to the product surface through the glue dispensing head 72. The curing structure 74 is used to make the glue dispensing head 72 continuously dispense glue while curing the glue dispensing material on the product surface, thereby ensuring the stability of the glue dispensing and avoiding the flow of the glue dispensing material during rotation or movement.

[0042] For further reference, Figure 3As shown, the curing structure 74 includes a focusing ring 741 and a curing lamp head 742; the focusing ring 741 is used to fix a plurality of curing lamp heads 742, the focusing ring 741 has an inner cavity, and the plurality of curing lamp heads 742 are arranged in a ring shape along the inner wall of the focusing ring 741, and the plurality of curing lamp heads 742 do not irradiate in a scattered manner, but condense the light into a straight line of UV light, and a plurality of UV rays are irradiated toward the dispensing head 72.

[0043] Specifically, when the dispensing head 72 moves up and down with the Z-axis moving component 4 to dispense glue to the product, a focusing ring 741 and a plurality of curing lamp heads 742 are used to irradiate a plurality of UV rays. When the dispensing of the product is completed, the UV rays can cure the dispensing material on the surface. At the same time, the UV rays are concentrated in the form of light to avoid scattered irradiation and increase the irradiation flux. Moreover, multiple UV rays can irradiate the product at the same time, which can improve the curing efficiency and further accelerate the curing speed.

[0044] In some embodiments, a plurality of curing lamp heads 742 are arranged tilted in the focusing ring 741, so that when a plurality of UV rays are irradiated toward the dispensing head 72, all UV rays converge into a point below the dispensing head 72. After the UV rays irradiation points converge into a point, the point is the position where the dispensing head 72 dispenses glue to the product. The tilted curing lamp heads 742 can allow the UV rays to irradiate at an angle, so that all UV rays can gather toward the position below the dispensing head 72 along the ring shape of the focusing ring 741. At the same time, the convergence point is located below the dispensing head 72, so that the UV rays do not contact the dispensing head 72, so that when the dispensing head 72 dispenses glue to the product, the UV rays will not irradiate the dispensing head 72, thereby preventing the UV rays from curing the glue outlet points of the dispensing head 72 and causing the dispensing head 72 to be blocked.

[0045] refer to Figure 3 As shown, the dashed line simulating UV light at the curing lamp head 472 extends to a convergence point below the dispensing head.

[0046] For further reference, Figure 4 As shown, a mounting inner cavity 7411 is opened in the focusing ring 741, and a plurality of irradiation ports 7412 are opened in the mounting inner cavity 7411. The number of curing lamp heads 742 is consistent with the irradiation ports 7412, and they correspond one-to-one with the irradiation ports 7412. The curing lamp heads 742 are located in the mounting inner cavity 7411, and the irradiation direction is toward the irradiation ports 7412, so that the irradiated UV light can irradiate from the irradiation ports 7412 toward the bottom of the dispensing head 72.

[0047] refer to Figure 4 As shown, the curing structure 74 is also connected to an adjustment structure 75, which is connected to the curing lamp head 742, and the adjustment end is located at the dispensing head 72. The adjustment structure 75 is used to adjust the angle of the curing lamp head 742, so the adjustment end is located at the curing lamp head 742.

[0048] Specifically, the curing lamp head 742 is located in the installation cavity 7411, and the inclination angle of the curing lamp head 742 can be adjusted using the adjustment structure 75, so as to adapt to the dispensing positions of different dispensing heads 72 or different products. For example, if the surface of the product is uneven, the angle of the curing lamp head 742 can be adjusted to adapt to the structure of the product.

[0049] In addition, when the dispensing head 72 rises with the moving end of the Z-axis moving component 4, the inclination angle of the curing lamp head 742 can be adjusted through the curing lamp head 742, so that the curing lamp head 742 continues to cure the product when the dispensing head 72 rises, thereby extending the curing time and improving the stability of the curing of the dispensing material.

[0050] Further, refer to Figure 4 As shown, the adjustment structure 75 includes an articulated frame 751, a reset portion 752, an adjustment portion 753 and a driving portion 754; the curing lamp head 742 is hinged to the articulated frame 751, so that the curing lamp head 742 can rotate along the articulated frame 751 to tilt and adjust the irradiation angle of the curing lamp head 742.

[0051] One end of the reset portion 752 is connected to the wall of the mounting cavity 7411, and the other end is connected to the curing lamp head 742. The reset portion 752 may be a spring, which may apply a reset elastic force to the curing lamp head 742 so that the curing lamp head 742 can restore the tilt angle.

[0052] The adjusting portion 753 is connected to the curing lamp head 742 and extends through the focusing ring 741 to the outer mounting cavity 7411. The adjusting portion 753 can be made of a pull rope or a pull line, and the material can be a metal material to ensure the stability of the connection. The driving portion 754 is connected to the outer wall of the dispensing head 72 and is connected to the side of the adjusting portion 753 away from the focusing ring 741. The driving portion 754 may include at least two sets of electric push rods or cylinders, and the telescopic ends of the electric push rods or cylinders are connected with The lifting ring is sleeved on the dispensing head 72, so that the lifting ring can be driven by the electric push rod or the cylinder to move up and down along the dispensing head 72. When the adjusting part 753 is a pull rope or a pull line, one end is tied to the curing lamp head 742, and the other end is tied to the lifting ring. When the electric push rod or the cylinder drives the lifting ring to move up and down, all the curing lamp heads 742 are driven to rotate along the articulated frame 751 through the adjusting part 753, so as to achieve the effect of uniformly adjusting the inclination angle of the curing lamp heads 742.

[0053] Specifically, the driving part 754 uniformly lifts and lowers all the adjusting parts 753 along the extension direction of the glue dispensing head 72. During the lifting process, all the adjusting parts 753 synchronously adjust the inclination angle of the curing lamp head 742 along the articulated frame 751 to adapt to different glue dispensing heads 72 or glue dispensing products. At the same time, when the glue dispensing head 72 rises and no longer dispenses glue, the inclination angle of the curing lamp head 742 can be adjusted to continue irradiating the glue dispensing material, thereby extending the irradiation time and improving the curing efficiency.

[0054] Among them, since the temperature of the dispensing material delivered by the dispensing head 72 is relatively high, it is easy to be transmitted to the driving part 754 through heat transfer, and the driving part 754 is easily damaged by heat. Therefore, a heat insulation frame 721 is also provided on the outer wall of the dispensing head 72, and the driving part 754 is installed on the heat insulation frame 721. The heat is blocked by the heat insulation frame 721 to ensure the stable driving of the driving part 754 and extend the service life of the driving part 754.

[0055] Furthermore, a guide opening 7413 is provided on the side of the focusing ring 741 away from the resetting portion 752, and the adjusting portion 753 passes through the guide opening 7413 and extends toward the driving portion 754. The guide opening 7413 provides a limiting and guiding function for the adjusting portion 753, thereby avoiding the position of the adjusting portion 753 from being offset and avoiding the situation where the irradiation angle of any curing lamp head 742 is inconsistent.

[0056] In some embodiments, reference Figure 4 As shown, the outer wall of the focusing ring 741 is also provided with a sensing part 755, and the sensor is electrically connected to the external controller 8. The sensing end of the sensing part 755 is consistent with the direction of the glue dispensing head 72. The sensing part 755 can adopt a distance sensor, a laser ranging sensor, etc., to detect the distance from the focusing ring 741 to the surface of the product. After sending the detection data to the background controller 8, the controller 8 obtains the required tilt angle of the curing lamp head 742 through the detection data and the ranging algorithm. Only then can the controller 8 accurately gather the convergence points irradiated by all the curing lamp heads 742 at the glue dispensing point of the product, and send a control instruction to the driving part 754, and use the driving part 754 to drive the adjustment part 753 to adjust the tilt angle of all the curing lamp heads 742.

[0057] This method can be faster and adaptable to various products, including after the dispensing is completed, or during the dispensing interval, such as when the dispensing head 72 rises, the sensor unit 755 can also measure the rising distance of the dispensing head 72 in real time, and then the controller 8 calculates the distance data and sends a control instruction to the driving unit 754, so that the convergence point of the curing lamp head 742 can always irradiate the dispensing material, thereby extending the irradiation time.

[0058] On the other hand, in addition to converging all UV rays into a convergence point, if the dispensing area is large and a large area or range needs to be irradiated, the driving unit 754 can continue to tilt so that the convergence points of all UV rays are staggered, thereby scattering the UV rays.

[0059] In addition to the method of staggering the convergence points of all UV rays, the following method can also be used.

[0060] A reflector 7414 is provided on the focusing ring 741 away from the irradiation port 7412, and the surface of the reflector 7414 is a prism. The reflecting mirror surface is uneven and can diffusely reflect the UV light. When the driving part 754 irradiates all the curing lamp heads 742 toward the reflector 7414 through the adjustment part 753, all the UV light is diffusely reflected, so that the focusing ring 741 scatters all the diffusely reflected UV light toward the product, thereby expanding the irradiation area.

[0061] Among them, the reflector 7414 has an inverted triangle mirror structure. Through the inverted triangle mirror structure of the reflector 7414, the UV light can be repeatedly reflected. At the same time, combined with the uneven mirror surface, the diffuse reflection range is wider.

[0062] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
