Technical Field
[0001] The utility model relates to the technical field of automatic glue dispensing, in particular to a glue dispensing mechanism and glue dispensing equipment. Background Art
[0002] In automotive panel products, there are many assembly requirements that require the application of different dispensing processes. For example, some panels require the application of a jet-type dispensing valve for dispensing, while some panels require the application of a screw-type dispensing valve for dispensing. However, the existing dispensing mechanism can only adapt to the dispensing operation of one dispensing process, which leads to the need to repeatedly assemble and disassemble and replace different dispensing mechanisms in actual production to meet the dispensing process of different products. The dispensing mechanism assembly and disassembly process is extremely time-consuming and labor-intensive, which affects and reduces the production efficiency of the product. In addition, the installation position of the dispensing mechanism will also have a large deviation during multiple assembly and disassembly processes, which makes it impossible to meet the requirements of higher dispensing accuracy.

[0005] A glue dispensing mechanism, comprising a Z-axis linear module, a slide, an image acquisition module, a rangefinder and at least two glue dispensing devices;
[0006] The image acquisition module, the rangefinder and the plurality of the dispensing devices are all connected to the slide, the image acquisition module is used to obtain the position information of the workpiece to be dispensed, the rangefinder is used to obtain the distance between itself and the workpiece to be dispensed, the Z-axis linear module is connected to the slide, and is used to simultaneously drive the slide, the image acquisition module, the rangefinder and the plurality of the dispensing devices to perform reciprocating lifting and lowering movements in the vertical direction, the Z-axis linear module is connected to the rangefinder signal, and each of the dispensing devices includes a connected driving cylinder and a dispensing valve, and the driving cylinder is used to drive the dispensing valve to perform reciprocating lifting and lowering movements in the vertical direction.

[0011] The present application also provides a dispensing device, comprising any of the dispensing mechanisms described above.
[0012] In one of the technical solutions, the dispensing equipment also includes a frame, an X-axis linear module, a dispensing platform and a Y-axis linear module;
[0013] The X-axis linear module and the Y-axis linear module are both connected to the frame, the dispensing platform is connected to the X-axis linear module, the Z-axis linear module in the dispensing mechanism is connected to the Y-axis linear module, the dispensing platform is used to carry the workpiece, the X-axis linear module is used to drive the dispensing platform to move along a first horizontal direction, the Y-axis linear module is used to drive the dispensing mechanism to move along a second horizontal direction, the X-axis linear module and the Y-axis linear module are respectively connected to the image acquisition module signal, and the first direction and the second direction are perpendicular to each other.

In addition, each dispensing device of the present solution is equipped with a driving cylinder, so that each dispensing device has a driving cylinder. The dispensing height of the dispensing valve can be controlled by the driving stroke of each driving cylinder, ensuring that when switching different dispensing devices, the dispensing valve actually used can perform dispensing operations on the workpiece at an appropriate height position, so as to quickly meet the dispensing needs of dispensing valves of different processes. Compared with the solution in which each dispensing valve is connected to a Z-axis linear module, this solution has only one Z-axis linear module, so the cost of this solution is lower. Moreover, the height to which the Z-axis linear module of this solution drives multiple dispensing devices to descend can be fine-tuned according to the data measured by the rangefinder, to ensure that no matter which dispensing device is switched to, the corresponding dispensing valve can dispense glue to the workpiece at an accurate height, thereby improving the dispensing accuracy of all dispensing devices.

[0028] Embodiment 1
[0029] Please also read Figure 1 and Figure 2, this embodiment provides a dispensing mechanism, including a Z-axis linear module 1, a slide 2, an image acquisition module 3, a rangefinder 4 and at least two dispensing devices 5, each dispensing device 5 specifically includes a connected driving cylinder 51 and a dispensing valve 52, and the driving cylinder 51 is used to drive the dispensing valve 52 to move up and down reciprocatingly in the vertical direction. Among them, the image acquisition module 3, the rangefinder 4 and all the dispensing devices 5 are installed on the slide 2, and the driving cylinders 51 of multiple dispensing devices 5 are installed on the slide 2. The Z-axis linear module 1 is connected to the slide 2 and is used to simultaneously drive the slide 2, the image acquisition module 3, the rangefinder 4 and multiple dispensing devices 5 to move up and down reciprocatingly in the vertical direction, and the rangefinder 4 is used to obtain the distance between itself and the workpiece, and the Z-axis linear module 1 is also used to obtain the height information of the workpiece detected by the rangefinder 4, so that the height value of the Z-axis linear module 1 driving the multiple dispensing devices 5 to descend can be adjusted, so that the dispensing device 5 can accurately perform dispensing operations on the workpiece at a suitable height position, thereby improving the accuracy of dispensing. Among them, the image acquisition module 3 can obtain the actual position of the workpiece to be glued, so that the entire glue dispensing mechanism can more accurately perform glue dispensing operations on the position where glue is required on the workpiece.
[0030] Specifically, when the workpiece is transported to the bottom of the dispensing mechanism, the Z-axis linear module 1 in the dispensing mechanism drives the slide 2 to descend, so that the image acquisition module 3, the rangefinder 4 and the multiple dispensing devices 5 all descend along with the descent of the slide 2, so that the multiple dispensing devices 5 quickly move downward toward the workpiece, and then the image acquisition module 3 takes a picture of the workpiece below, and the background system calculates the actual position information of the workpiece, and then calibrates the relative position of the entire dispensing mechanism and the workpiece in the horizontal direction, ensuring that a dispensing device 5 in actual application can more accurately dispense the required glue on the workpiece. The dispensing operation is performed at the position. At the same time, the rangefinder 4 obtains the distance between itself and the workpiece to be dispensed. The Z-axis linear module 1 fine-tunes the height of the slide 2 according to the data measured by the rangefinder 4, thereby fine-tuning the height of multiple dispensing devices 5, so that the dispensing device 5 actually used can accurately dispense glue on the workpiece at a suitable height position, thereby further improving the accuracy of dispensing. Finally, the driving cylinder 51 in a dispensing device 5 actually used drives a corresponding dispensing valve 52 to descend, so that the dispensing valve 52 actually used descends to the specified height and dispenses glue on the workpiece.
[0031] The image acquisition module 3 preferably includes a camera 31, a lens 32 and a light source 33, which are all fixed on the slide 2 and arranged vertically downward in sequence. The rangefinder 4 is preferably an existing laser displacement sensor. The Z-axis linear module 1 is preferably a screw linear module with high precision. The Z-axis linear module 1 can also be a synchronous belt module or a linear motor. In addition, in this embodiment, the dispensing valve 52 in at least one dispensing device 5 is a spray valve that uses a jet-type dispensing valve, and the dispensing valve 52 in at least one dispensing device 5 is a screw valve that uses a screw extrusion type dispensing valve.
[0032] In summary, the present technical solution sets up a plurality of dispensing devices 5 to adapt to the dispensing valves 52 required for various dispensing processes, and each dispensing device 5 of the present solution is equipped with a driving cylinder 51, so that the dispensing height of the dispensing valve 52 in each dispensing device 5 can be controlled by the driving stroke of each driving cylinder 51, ensuring that when switching different dispensing devices 5, the dispensing valve 52 actually used can perform dispensing operations on the workpiece at a suitable height position, so as to quickly meet the dispensing requirements of the dispensing valves 52 of different processes, which is similar to the solution in which each dispensing valve 52 is connected to a Z-axis linear module 1. In comparison, since the present solution has only one Z-axis linear module 1, the cost of the present solution is lower. The Z-axis linear module 1 of the present solution drives the multiple dispensing devices 5 to descend to a height that can be fine-tuned according to the data measured by the rangefinder 4 to ensure that no matter which dispensing device 5 is switched to, the corresponding dispensing valve 52 can dispense glue to the workpiece at an accurate height, thereby improving the dispensing accuracy of all dispensing devices 5; in addition, the image acquisition module 3 can obtain the actual position of the workpiece to be dispensed, so that the dispensing mechanism can more accurately perform dispensing operations on the required dispensing position on the workpiece, thereby further improving the dispensing accuracy of all dispensing devices 5.
[0033] Embodiment 2
[0034] See also Figure 3 This embodiment provides a dispensing device, which includes a frame 10, an X-axis linear module (not shown in the figure), a Y-axis linear module 20, a dispensing platform 30 and the dispensing mechanism 40 described in the above-mentioned embodiment one.
[0035] In this embodiment, the X-axis linear module and the Y-axis linear module 20 are both fixed on the frame 10, and the dispensing platform 30 is installed on the X-axis linear module. The X-axis linear module is used to drive the dispensing platform 30 to move along the first horizontal direction (i.e., the X-axis). The dispensing platform 30 is used to carry one or more workpieces. The Z-axis linear module 1 in the dispensing mechanism 40 is connected to the Y-axis linear module 20, and the Y-axis linear module 20 is used to drive the entire dispensing mechanism 40 to move along the second horizontal direction (i.e., the Y-axis). In addition, the image acquisition module 3 in the dispensing mechanism 40 is respectively connected to the X-axis linear module and the Y-axis linear module 20 by signal, so that the X-axis linear module and the Y-axis linear module 20 can be linked according to the position information of the workpiece collected by the image acquisition module 3 and calibrate the relative position of the entire dispensing mechanism 40 and the dispensing platform 30, so that a corresponding dispensing device 5 in the dispensing mechanism 40 can accurately dispense glue to the workpiece on the dispensing platform 30 to improve the accuracy of dispensing.
[0036] The X-axis and the Y-axis are preferably perpendicular to each other, and through the linkage of the X-axis linear module and the Y-axis linear module 20, each dispensing device 5 in the dispensing mechanism 40 can draw a straight line, a circle or other arc curves on the workpiece when dispensing glue on the workpiece. The Y-axis linear module 20 is preferably a linear motor with a faster speed.
[0037] In other embodiments, the X-axis linear module and the Y-axis linear module 20 can be overlapped together in sequence on the frame 10, and then the Z-axis linear module 1 in the dispensing mechanism 40 can be installed on the frame 10. At this time, the relative positions of the dispensing platform 30 and the dispensing device 5 can be calibrated before the dispensing device 5 dispenses glue, and the dispensing device 5 can also realize operations such as drawing straight lines, circles or other arc curves on the workpiece.
[0038] In summary, since the dispensing mechanism 40 in the first embodiment is adopted, the dispensing device can also switch the advantages of different dispensing valves 52 according to different dispensing processes, and also has the advantages of high dispensing accuracy and low cost.
[0039] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
