In double-valve or multi-valve dispensing machines, due to the presence of these cables and air pipes, interference will occur when two adjacent dispensing mechanisms are close to each other. In some small space application scenarios, for example, when the minimum distance between two adjacent products to be dispensed is 60mm, in existing dispensing machines, the minimum distance between two adjacent dispensing mechanisms exceeds 60mm, and the application scenarios are limited.

DETAILED DESCRIPTION

[0026] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0027] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 6 As shown, the compact dispensing device of the utility model comprises: a dispensing assembly 1, a z-axis driving mechanism 2, a y-axis fine-tuning mechanism 3 and a visual mechanism 4, wherein the z-axis driving mechanism 2 comprises: a z-axis substrate 21, the z-axis substrate 21 is connected to the dispensing assembly 1, the y-axis fine-tuning mechanism 3 is connected to the z-axis driving mechanism 2, and the visual mechanism 4 is connected to the z-axis substrate 21. Among them, a junction box 10 is provided on the z-axis substrate 21, a first drag chain 51 and a second drag chain 52 are provided on the z-axis driving mechanism 2, and the cables of the y-axis fine-tuning mechanism 3 and the visual mechanism 4 are inserted into the junction box 10 after passing through the z-axis substrate 21; the output cables of the junction box 10 and the air pipe of the dispensing assembly 1 enter the second drag chain 52, and the cables of the z-axis driving mechanism 2 enter the first drag chain 51.

[0030] The utility model arranges the functional components reasonably and sets the junction box 10, so that the cables of the y-axis fine-tuning mechanism 3 and the visual mechanism 4 can be tied together and then inserted into the junction box 10 through the z-axis substrate 21. The junction box 10 then uniformly leads out an output cable and the cable of the dispensing component 1 into the second drag chain 52, and the cable of the z-axis drive mechanism 2 directly enters the first drag chain 51 after being tied. After overall optimization, the width above the dispensing device can be reduced to dmm (for example, d=53), which can prevent the cables of two adjacent dispensing devices from interfering with each other and meet the application scenarios of small spaces.

[0031] For example, the z-axis driving mechanism 2 further includes: a z-axis mounting frame 22, a z-axis driving member 23, a z-axis coupling 24 and a z-axis screw module 25. The z-axis driving member 23 is mounted on the z-axis mounting frame 22. The z-axis screw module 25 is connected to the z-axis driving member 23 through the z-axis coupling 24. The z-axis substrate 21 is connected to the z-axis screw module 25. When the z-axis driving member 23 is started, the slider of the z-axis screw module 25 can move up and down along the z-axis, thereby driving the z-axis substrate 21 to move up and down. The dispensing assembly 1 is connected to the z-axis substrate 21, thereby realizing the position change of the dispensing assembly 1 on the z-axis.

[0032] For example, the dispensing device further includes: a first mounting plate 7, a second mounting plate 8 and a third mounting plate 9, one end of the first drag chain 51 is connected to the third mounting plate 9, the other end of the first drag chain 51 is connected to the second mounting plate 8, one end of the second drag chain 52 is connected to the second mounting plate 8, and the other end of the second drag chain 52 is connected to the first mounting plate 7. The first mounting plate 7 is fixedly connected to the z-axis substrate 21. When the z-axis substrate 21 moves up and down, the first mounting plate 7 will also move up and down, and the other end of the second drag chain 52 will also move up and down with the first mounting plate 7. The second mounting plate 8 is fixed on the pneumatic mounting plate (not shown in the figure) on the x-axis beam. The third mounting plate 9 is connected to the z-axis mounting frame 22. The y-axis fine-tuning mechanism 3 is connected to the side of the z-axis screw module 25 away from the z-axis substrate 21. The y-axis fine-tuning mechanism 3 can drive the z-axis drive mechanism 2 to move along the y-axis as a whole. When the z-axis drive mechanism 2 moves along the y-axis, one end of the first drag chain 51 will also move along the y-axis. For example, the first drag chain 51 and the second drag chain 52 are both flexible drag chains, and the first drag chain 51 and the second drag chain 52 are both located above the z-axis drive mechanism 2. For example, the second drag chain 52 is bent toward the front of the z-axis drive mechanism 2, and the first drag chain 51 is bent toward the rear of the z-axis drive mechanism 2. In this way, it is convenient for the cables to pass in and out. A part of the second drag chain is located directly above the first drag chain. For example, the orthographic projection of the second drag chain 52 on the horizontal plane covers the orthographic projection of the first drag chain 51 on the horizontal plane. In other words, the width and length of the first drag chain 51 are both smaller than the second drag chain 52, which is conducive to further optimizing the installation space.

[0033] For example, the dispensing device further includes: a valve body mounting seat 6, the valve body mounting seat 6 is connected to the z-axis substrate 21, the dispensing assembly 1 is connected to the valve body mounting seat 6, and the valve body mounting seat 6 is hollow. A threading hole 211 is provided on the z-axis substrate 21. The installation position of the valve body mounting seat 6 corresponds to the position of the threading hole 211, and the wiring box 10 is located above the valve body mounting seat 6, so that the cables of the visual mechanism 4 and the y-axis fine-tuning mechanism 3 are tied and passed through the threading hole 211, and then passed through the valve body mounting seat 6 to be inserted into the wiring box 10.

[0034] In the prior art, the junction box 10 is not provided, and the dispensing assembly 1 is directly connected to the z-axis substrate 21. The utility model improves the routing of cables, and the cables pass through the z-axis substrate 21 and are connected to the junction box 10. By providing the valve body mounting seat 6, the space between the z-axis substrate 21 and the dispensing assembly 1 can be expanded, and space is reserved for cable routing.

[0035] For example, a wiring fixing block 212 is provided on the z-axis substrate 21. The wiring fixing block 212 is provided with a plurality of grooves that can clamp the cables. The dispensing assembly 1 includes a dispensing valve 101 and a glue cylinder 102. The glue cylinder 102 is connected to the fluid seat of the dispensing valve 101 through an air pipe. The air pipe at the top of the glue cylinder 102 is connected to an external air supply assembly. The air supply assembly supplies air and pressurizes the glue cylinder 102 through the air pipe to realize glue discharge. For example, a pressure sensor 11 is also provided on the first mounting plate 7. The air pipe at the top of the glue cylinder 102 is connected to the pressure sensor 11. The air pipe connected to the pressure sensor 11 enters the second drag chain 52. The distance between the pressure sensor 11 and the second drag chain 52 is very close, so that interference between the air pipe and other cables can be prevented. The pressure sensor 11 can also detect whether the pressure entering the glue cylinder 102 is accurate.

[0036] For example, the y-axis fine-tuning mechanism 3 includes: a y-axis driving member 31, a y-axis coupling 32, a y-axis screw module 33, a mounting base 34 and a module base 35, the mounting base 34 is connected to the z-axis driving mechanism 2, the y-axis driving member 31 is connected to the y-axis screw module 33 through the y-axis coupling 32, the y-axis screw module 33 is connected to the mounting base 34, the module base 35 is used to install the y-axis screw module 33, and two limit photoelectric devices 36 are provided on the module base 35. The mounting base 34 is connected to the side of the z-axis screw module 25 away from the z-axis substrate 21. The module base 35 is connected to the x-axis crossbeam (not shown in the figure). The y-axis screw module 33 is installed on the module base 35, and the slider of the y-axis screw module 33 is connected to the mounting base 34. When the y-axis driving member 31 is started, the slider on the y-axis screw module 33 can be moved along the y-axis, thereby driving the mounting base 34 to move along the y-axis, and realizing the position change of the z-axis driving mechanism 2 on the y-axis. The limit photoelectric 36 can prevent the moving stroke of the mounting base 34 from exceeding the safe moving range. The range in which the mounting base 34 can move is the distance between two limit photoelectric 36.

[0037] For example, the y-axis driving member 31 is a servo motor with a precision compensation function. The y-axis fine-tuning mechanism 3 also includes a driver that matches the y-axis driving member 31. The driver is connected to the y-axis driving member 31. Through the detection of the laser interferometer, the position uncertainty of the ordinary servo motor is 14μm, while the position uncertainty of the servo motor with the precision compensation function can reach 4.1μm, which significantly improves the positioning accuracy.

[0038] For example, the visual mechanism 4 includes: a light source mounting seat 41, a camera mounting plate 42, a light source 43, a camera 44 and a lens 45. The light source mounting seat 41 is connected to the z-axis substrate 21, the camera mounting plate 42 is fixedly connected to the light source mounting seat 41, the light source 43 is connected to the light source mounting seat 41, the camera 44 is connected to the camera mounting plate 42, and the lens 45 is connected to the camera 44. An aviation plug 46 is provided on the camera mounting plate 42, and the length direction of the aviation plug 46 is parallel to the length direction of the camera mounting plate 42. In this way, it is convenient for the light source line and the camera line of the visual mechanism 4 to pass through the threading hole 211.

[0039] In summary, by reasonably arranging the installation of functional components and setting up the junction box 10, the cables of the y-axis fine-tuning mechanism 3 and the visual mechanism 4 can be tied together and then inserted into the junction box 10 through the z-axis substrate 21. The junction box 10 then uniformly leads out an output cable and the cable of the dispensing component 1 into the second drag chain 52, and the cable of the z-axis drive mechanism 2 is directly tied into the first drag chain 51. After overall optimization, the width above the dispensing device can be reduced so that the cables between two adjacent dispensing devices will not interfere with each other, which can meet the application scenarios of small spaces.
