Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically a five-axis dispensing machine. Background Technology

[0002] A dispensing machine, also known as a glue applicator, glue sprayer, glue applicator, or glue dispensing machine, is an automated device specifically designed for fluid control. It can perform three-dimensional and four-dimensional path dispensing, primarily used for precisely dispensing, injecting, coating, or dripping adhesives, paints, and other liquids onto precise locations on each product during manufacturing processes. It can be used to apply dots, lines, circles, or arcs. Existing four-axis or five-axis dispensing machines place the workpiece on a lower platform to allow movement / rotation along several axes. The upper and lower platforms together achieve five degrees of freedom. This means that current five-axis dispensing machines can only process the workpiece by placing it on the lower platform, requiring an additional lower platform installation besides the dispensing machine itself, increasing both workload and floor space.

[0003] In the prior art, patent announcement number CN212975682U discloses a five-axis dispensing machine in the field of dispensing machines. The dispensing machine includes a frame, a dispensing assembly, a two-axis movable mechanism that moves along the X and Z axes, and a three-axis movable mechanism that moves along the Y, R, and A axes. The two-axis movable mechanism and the three-axis movable mechanism are both fixedly mounted on the frame. The three-axis movable mechanism is characterized by having a processing position. The dispensing assembly includes a dispensing valve and a camera assembly, and the dispensing valve and the camera assembly are both mounted on the two-axis movable mechanism. The positions of the dispensing valve and the camera assembly correspond to the processing position.

[0004] The aforementioned patent requires the workpiece to be processed to be placed on the lower platform during use, which necessitates the additional installation of the lower platform in addition to the dispensing machine, increasing both workload and floor space. Therefore, we need to propose a five-axis dispensing machine. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a five-axis dispensing machine, such as... Figure 1-4As shown, the device includes a worktable 1, a mounting plate 6, a dispensing head 15, and a moving plate 19. Above the worktable 1, via support frames 4, are X-axis motion mechanisms 5 and 7 for moving the mounting plate 6 along the X and Y axes. On the side of the mounting plate 6, a Z-axis motion assembly is provided for moving the dispensing head 15 along the Z axis. A shelf 3 is provided on the upper surface of the worktable 1, and two sets of support frames 4 are provided on the upper surface of the worktable 1. The shelf 3 is located between the two sets of support frames 4 and below the dispensing head 15. The X-axis motion mechanism 5, the Y-axis motion mechanism 7, and the shelf 3 are all existing structures. By adding new Z-axis, U-axis, and R-axis motion assemblies to the existing X-axis and Y-axis motion mechanisms that move the mounting plate 6, a five-axis dispensing effect is achieved while avoiding the need for an additional lower processing platform. This reduces installation workload and floor space. Furthermore, casters and a telescopic base are provided on the lower surface of the worktable 1 for easy movement of the dispensing machine.

[0026] Preferably, the lower surface of the movable plate 19 is provided with an R-axis motion assembly for driving the dispensing head 15 to rotate along the R-axis. The R-axis motion assembly includes a connecting column 8, an extension plate 20, and an R-axis drive module. The dispensing head 15 is disposed on one side of the extension plate 20, and the extension plate 20 is connected to the movable plate 19 through the connecting column 8. The R-axis drive module includes an R-axis motor 14, a partition plate, and a rotating column. The R-axis motor 14 is bolted to the side of the partition plate away from the dispensing head 15. The partition plate is bolted to the bottom end of the connecting column 8. The rotating column is keyed to the output end of the R-axis motor 14, and one end of the rotating column is rotatably connected to the partition plate. One end of the rotating column passing through the partition plate is fixedly connected to the extension plate 20. When the R-axis motor 14 is started, the rotating column drives the extension plate 20 to rotate along the R-axis. The connecting column 8 and the partition plate support the R-axis motor 14, thereby achieving the effect of driving the dispensing head 15 on the side of the extension plate 20 to rotate along the R-axis.

[0027] Furthermore, the upper surface of the movable plate 19 is provided with a U-axis motion assembly for connecting the column 8 to rotate along the U-axis; the U-axis motion assembly includes a U-axis motor 2, a lower driven gear 13, a lower drive gear 17, and a lower belt 18. The U-axis motor 2 is bolted to the upper surface of the movable plate 19. The lower drive gear 17 is keyed to the output end of the U-axis motor 2 through an extension column. The lower driven gear 13 is rotatably disposed on the lower surface of the movable plate 19, and the lower belt 18 is sleeved on the outer arc surface of the lower driven gear 13 and the lower drive gear 17. When the U-axis motor 2 is started, it drives the lower drive gear 17 to rotate. The lower drive gear 17 drives the lower driven gear 13 to rotate through the lower belt 18. The lower driven gear 13 then drives the partition to rotate through the connecting column 8, thereby driving the extension plate 20 on the side of the partition to rotate, thus achieving the effect of driving the dispensing head 15 to rotate along the U-axis.

[0028] Furthermore, the Z-axis motion assembly includes a moving block 12, a connecting rod 16, a lead screw 21, and a Z-axis drive module. The moving block 12 is configured as a protrusion, and the side of the mounting plate 6 has a moving groove corresponding to the moving block 12. The lead screw 21 is rotatably disposed inside the moving groove, and the moving block 12 is threaded onto the outer arc surface of the lead screw 21. The moving block 12 is fixedly connected to the moving plate 19 through the connecting rod 16. The moving block 12 is configured as a protrusion that fits into the moving groove on the side of the mounting plate 6, thereby ensuring that when the lead screw 21 rotates, it can drive the moving block 12 to move up and down along the moving groove, while preventing the moving block 12 from rotating with the lead screw 21. Then, the moving block 12 drives the moving plate 19 to move up and down through the connecting rod 16, thereby achieving the effect of driving the dispensing head 15 to move up and down along the Z-axis.

[0029] It is worth noting that the Z-axis drive module includes an upper drive gear 9, an upper belt 10, an upper driven gear 11, and a Z-axis motor. The Z-axis motor is bolted to one side of the mounting plate 6. The upper drive gear 9 and the upper driven gear 11 are both rotatably mounted on the upper surface of the mounting plate 6. The upper drive gear 9 is connected to the output end of the Z-axis motor via another set of rotating columns. The top end of the lead screw 21 is fixedly connected to the upper driven gear 11. The upper belt 10 and the lower belt 18 are both toothed belts. The upper belt 10 is meshed with the outer arc surface of the upper drive gear 9 and the upper driven gear 11, and the lower belt 18 is meshed with the outer arc surface of the lower driven gear 13 and the lower drive gear 17. When the Z-axis motor is started, it drives the upper drive gear 9 to rotate. The upper drive gear 9 drives the upper driven gear 11 to rotate via the upper belt 10. The upper driven gear 11 then drives the lead screw 21 to rotate. The lead screw 21 drives the moving block 12 to move up and down via a thread, thereby ensuring the stability of the Z-axis movement.

[0030] Specifically, the Z-axis motor, U-axis motor 2, and R-axis motor 14 mentioned in the text can all be Dynamixel XM540-W270-R intelligent servo motors. These require an external battery, but can be used with portable battery packs, such as the 3S LiPo 2200mAh, thus reducing the impact of external power connections on the normal operation of the dispensing head 15. They can also be remotely controlled via wireless modules, such as Zigbee / XBee; simultaneously, each motor can be controlled via a 2D2 + wireless serial port module, such as the HC-05 Bluetooth or NRF24L01, thereby reducing the workload of operators.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
