Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, and in particular to a dispensing device for processing oblique drill bits. Background Technology

[0002] In modern precision machining, especially in the production of cutting tools such as cutting tools and drills, dispensing technology is widely used in various stages such as surface treatment, bonding reinforcement, and coating enhancement, aiming to improve the wear resistance, corrosion resistance, and overall service life of workpieces. Particularly in the machining of zigzag drills, the complex structure and unique surface morphology of the drill bit place higher demands on the precision, uniformity, and operational stability of dispensing. Traditional dispensing methods often rely on manual operation or single-channel automated equipment, which is not only inefficient but also makes it difficult to ensure the consistency of dispensing position and precise control of adhesive quantity, easily leading to uneven adhesive distribution, overflow, or leakage, thus affecting product quality and production efficiency. Furthermore, some existing dispensing devices suffer from insufficient rigidity in their structural design, low motion control precision, and poor adaptability, making it difficult to meet the demands of high-precision, high-efficiency modern production.

[0003] Chinese patent discloses a dispensing device (publication number: CN 219943428 U) comprising a cylinder, a housing, a support assembly, and a drive component. The housing includes a flexible sleeve, a rigid nozzle, and a seal. The flexible sleeve is integrally formed and contains silicone. An opening is provided on the flexible sleeve, the edge of which fits onto the outer wall of one end of the rigid nozzle. The other end of the rigid nozzle has a dispensing port. The seal seals the gap between the edge of the opening and the outer wall of the rigid nozzle. The support assembly includes a support member and a pressing member. The pressing member is detachably disposed within the cylinder and can slide within the cylinder in a first direction. The support member is fixed within the cylinder. However, this dispensing device suffers from low efficiency, poor accuracy, insufficient structural rigidity, inaccurate motion control, and poor adaptability, making it difficult to meet the high requirements for dispensing accuracy, efficiency, and stability during the processing of zigzag drill bits. Therefore, a dispensing device for processing zigzag drill bits is needed. Utility Model Content

Example

[0020] Please see Figure 1-4 As shown, a dispensing device for processing zigzag drill bits includes a base module 4. The base module 4 has a worktable 2 at its top center, and a workpiece reference surface 1 at its top center. An XYZ three-axis moving platform is mounted on the base module 4, comprising an X-axis module, a Y-axis module, and a Z-axis module. A dual-channel dispensing actuator is mounted on the Z-axis module. This device, by setting up the XYZ three-axis moving platform, enables flexible movement of the dispensing mechanism in three-dimensional space, making the dispensing operation more precise and controllable. The workpiece reference surface 1 on the worktable 2 provides a stable positioning base for the zigzag drill bit, helping to improve the accuracy of the dispensing position. The dual-channel dispensing actuator improves dispensing efficiency and meets complex processing requirements.

[0021] In this embodiment, the dual-channel dispensing actuator includes a first dispensing component 29 and a second dispensing component 30 arranged side by side.

The dispensing needle 11 is located directly below the glue chamber 9, with a compact structure, which helps to improve dispensing accuracy.

[0022] In this embodiment, the X-axis module includes a support frame 14, with two sets of support frames 14 arranged correspondingly. An X-axis guide rail 13 is mounted on each support frame 14, and two bearing seats are mounted on each X-axis guide rail 13, also arranged correspondingly.

A first linear guide shaft 12 is provided on one side of the X-axis lead screw. The X-axis module adopts a double support frame 14 and double bearing seat structure, enhancing the overall structural stability and load-bearing capacity. The cooperation between the X-axis lead screw and the servo motor achieves high-precision movement control in the X-axis direction. The linear guide shaft further improves the smoothness of the slide movement, reduces vibration and deviation, and ensures the accuracy of the dispensing path.

[0023] In this embodiment, the Y-axis module includes a Y-axis mounting frame 19. A second linear guide shaft 20 is provided on one side of the top of the Y-axis mounting frame 19. A Y-axis connecting plate 24 is provided on one side of the Y-axis mounting frame 19. A bracket is provided on one side of the Y-axis connecting plate 24.

The servo motor drive makes the Y-axis movement smoother and more controllable, which helps to improve the overall accuracy of the dispensing operation.

[0024] In this embodiment, the Z-axis module includes a Z-axis mounting frame. A Z-axis drive servo motor 26 is mounted on the top of the Z-axis mounting frame. One end of the Z-axis drive servo motor 26 is connected to a Z-axis lead screw 28. A Z-axis slide 27 is mounted on one side of the Z-axis lead screw 28. A Z-axis connecting frame is mounted on one side of the Z-axis slide 27. An adjustable support screw 6 is mounted on the Z-axis connecting frame. The adjustable support screw 6 is associated with a dual-channel dispensing actuator. An L-shaped connecting plate 21 is mounted on one side of the Z-axis mounting frame. The L-shaped connecting plate 21 is associated with and cooperates with a second linear guide shaft 20. The Z-axis module uses a servo motor to drive the lead screw, achieving precise lifting control in the Z-axis direction to meet the dispensing needs of workpieces of different heights. The adjustable support screw 6 allows for flexible adjustment of the height of the dispensing actuator, enhancing the adaptability and flexibility of the device. The cooperation between the L-shaped connecting plate 21 and the second linear guide shaft 20 further improves the stability and guidance of the Z-axis movement, ensuring smooth operation of the mechanism during dispensing.

[0025] In this embodiment, the worktable 2 is provided with multiple T-slots 3, the number of which is 20 to 30 and arranged in an equally spaced array. The multiple T-slots 3 on the worktable 2 provide ample mounting positions for fixtures or fixing devices, facilitating flexible adjustment and fixation according to different workpiece shapes and sizes. The equally spaced array design of the T-slots 3 makes the fixture layout more regular, helping to improve the repeatability and stability of workpiece positioning, thereby enhancing the consistency and reliability of the dispensing operation.

[0026] The implementation principle of this embodiment is as follows:

[0027] First, the helical drill bit to be processed is firmly placed on the worktable 2 at the top center of the base module 4. The workpiece reference surface 1 on the worktable 2 provides a precise positioning base for the drill bit, ensuring that it remains stable during processing without shifting or shaking. At the same time, the multiple T-slots 3 set on the worktable 2 can be used to install different types of clamps or fixing devices, so that the workpiece can be flexibly and reliably fixed according to its specific shape and size, further improving positioning accuracy and operational stability.

[0028] Next, the XYZ three-axis moving platform begins to operate. The X-axis module, through the X-axis guide rail 13 on the support frame 14 and the bearing seat, drives the X-axis slide 15 to move precisely along the X-axis direction under the drive of the servo motor. The Y-axis module, through the Y-axis guide rail 23 in the Y-axis mounting frame 19 and the bracket structure, controls the Y-axis slide 22 to move along the Y-axis direction under the drive of the servo motor. The Z-axis module, through the Z-axis drive servo motor 26 on the top of the Z-axis mounting frame, drives the Z-axis guide rail 28 to rotate, causing the Z-axis slide 27 to move up and down along the Z-axis direction. At the same time, the adjustable support screw 6 set on the Z-axis connecting frame can flexibly adjust the vertical position of the dual-channel dispensing actuator according to the height of the workpiece and the dispensing requirements, ensuring that the dispensing needle 11 and the workpiece surface always maintain a suitable distance and angle.

[0029] Under the coordinated control of the XYZ three-axis moving platform, the dual-channel dispensing actuator is precisely moved to the preset dispensing position; the dispensing valve assembly inside each dispensing component starts to work, and the screw pump 7, under the control of the servo motor or dedicated driver, stably and evenly delivers the adhesive from the adhesive chamber 9 to the dispensing needle 11. The pressure sensor 8 monitors the pressure changes during the adhesive delivery process in real time to ensure the stability of the adhesive flow and pressure, and avoids the phenomena of adhesive leakage, overflow, or uneven adhesive volume; under precise position control, the dispensing needle 11 accurately sprays or drips the adhesive onto the designated surface area of ​​the zigzag drill bit to complete single-point or multi-point dispensing operations.

[0030] Because the first dispensing component 29 and the second dispensing component 30 in the dual-channel dispensing actuator are designed to be arranged in parallel and have the same structure, the two dispensing components can perform dispensing operations synchronously, which not only greatly improves dispensing efficiency, but also makes maintenance and replacement more convenient through modular design. During the entire dispensing process, the high rigidity support structure of each axis module and the cooperation of precision lead screws and guide shafts ensure the stability and path accuracy of the dispensing mechanism during movement, effectively avoiding the impact of vibration and deviation on dispensing quality.
