[0002] A dental bur is a consumable instrument used by dentists. It is a very thin steel needle consisting of a needle tip and a needle handle. It can be inserted into a high-speed or low-speed handpiece to help dentists make cavities and repair teeth.

[0003] When electroplating the needle, it is not necessary to electroplat the entire outer periphery of the needle. Ink is used to isolate areas where electroplating is not required.

[0004] Most existing needle coating methods rely on manual application. Because the needles are very thin, they are inconvenient to handle manually. Furthermore, prolonged work can lead to fatigue, resulting in coating errors or uneven application, which affects product quality and reduces work efficiency.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] An ink and glue dispensing device for machining needles, such as Figures 1-4 As shown, it includes a machine body 1, a work platform 11 mounted on the machine body 1, a gantry frame 2 fixedly connected to the work platform 11, a dispensing module mounted on the gantry frame 2, and a clamping fixture 82 mounted below the gantry frame 2 for clamping the needle. The dispensing module is fixedly connected to the lifting end of the lifting module 21. A support platform 3 is slidably connected to the top of the work platform 11 along the width direction of the crossbeam of the gantry frame 2. A drive motor 81 for driving the clamping fixture 82 to rotate is fixedly connected to the top of the support platform 3. The clamping fixture 82 is mounted on the top of the support platform 3.

[0025] The dispensing module includes a support member 5 fixedly connected to the lifting end of the lifting module 21 and a syringe 6 disposed on the support member 5 for containing ink. The top of the support member 5 has a first support portion 51 for supporting the syringe 6 body, and the bottom of the support member 5 has a second support portion 52 for supporting the syringe 6 tip. Both the first and second support portions 51 and 52 have clamping components for holding the syringe 6. The first and second support portions 51 and 52 respectively have through holes 53 for the syringe 6 body and tip to pass through, with the syringe 6 fitting into the through holes 53 for easy insertion. The clamping components include a pressing member 7 that moves radially along the through holes 53 and a driving member 71 disposed on the side of the pressing member 7 away from the syringe 6. The driving member 71 is disposed on either the first or second support portion 51. On the support 52, the side of the extrusion member 7 near the syringe 6 is made of rubber. The driving member 71 is a screw, which is threadedly connected to the first support 51 or the second support 52. By rotating the screw, the extrusion member 7 can be driven to move radially along the through hole 53. When the syringe 6 is located in the through hole 53, the extrusion member 7 extrudes the outer peripheral wall of the syringe 6, thereby stably fixing the syringe 6 to one side of the support 5. A dispensing needle is provided at the head of the syringe 6. The dispensing needle limits the flow rate of ink in the syringe 6, making the dispensing more precise. When the syringe 6 is placed vertically, the ink will not leak from the head due to gravity. The top of the syringe 6 is connected to an air tube 61, which is connected to an air pump. The air pump is used to extrude or add ink in the syringe 6, improving work efficiency.

[0026] The lifting module 21 can be a cylinder or a linear motor module. The driving end of the lifting module 21 is fixedly connected to a lifting plate. A hollow protective shell 4 is fixedly connected to the side of the lifting plate away from the lifting module 21. The support member 5 is fixedly connected to the inner wall of the protective shell 4 near the lifting module 21. The dispensing module is set inside the protective shell 4. The bottom of the support member 5 extends out of the protective shell 4. The protective shell 4 can be used to set the support member 5 and the syringe 6 inside the protective shell 4, protecting the syringe 6 and ensuring the service life of the overall structure. The lifting module 21 can drive the syringe 6 to move in the vertical direction, so that the syringe 6 can move closer to or away from the needle on the top of the support platform 3, improving work efficiency. An ultraviolet lamp 9 is fixedly connected to the outer wall of the protective shell 4 away from the lifting module 21. After the dispensing of glue to the needle is completed, the ultraviolet lamp 9 is turned on to accelerate the curing of ink, prevent ink from falling off, and ensure ink coating efficiency.

[0027] The machine body 1 is equipped with a horizontal drive module. The housing of the horizontal drive module adopts a cylinder or linear motor module. A support platform 3 is fixedly connected to the work platform 11, and a slide rail 12 is fixedly connected to the top. The length direction of the slide rail 12 is parallel to the width direction of the crossbeam of the gantry frame 2. The bottom of the support platform 3 is fixedly connected to a sliding member 31 sleeved on the slide rail 12. The drive end of the horizontal drive module is fixedly connected to the sliding member 31. By setting the cooperation between the slide rail 12 and the sliding member 31, the movement trajectory of the support platform 3 is restricted, making the movement of the support platform 3 more stable. Driving the horizontal drive module, the support platform 3 is moved along the width direction of the crossbeam of the gantry frame 2, thereby moving away from or closer to the syringe 6. It can move the support platform 3 away from the gantry frame 2, which makes it convenient for personnel to install needles, and can automatically move closer to the syringe 6 without manual operation, thus improving work efficiency.

[0028] The top of the support platform 3 is fixedly connected to a support frame 8 with an L-shaped cross section by bolts. The drive motor 81 is fixedly connected to the inner wall of the support frame 8. The output shaft of the drive motor 81 passes through the support frame 8 and is fixedly connected to the clamping fixture 82 through a coupling. By setting the drive motor 81, the entire clamping fixture 82 can be rotated, thereby rotating the needle. When the needle is dispensing glue using the dispensing module, the needle rotates, making the dispensing more uniform and ensuring product quality. The clamping fixture 82 has a mounting hole in the middle for inserting the needle. The mounting hole abuts against the outer peripheral wall of the needle. The friction between the mounting hole and the outer peripheral wall of the needle is used to fix the needle, making it easier to fix the needle on the clamping fixture 82.

[0029] Working principle: The support frame 8 is fixedly connected to the corresponding position on the support platform 3 with bolts, and the drive motor 81 and clamping fixture 82 are installed. The horizontal drive module moves the support platform 3 away from the gantry 2 and closer to the operator, making it easier for the operator to insert the needle into the clamping fixture 82. After the needle is installed, the horizontal drive module moves the support platform 3 closer to the gantry 2 until the needle is below the syringe 6. The lifting module 21 drives the syringe 6 closer to the needle. Then, the drive motor 81 is started, driving the clamping fixture 82 to rotate and rotating the needle. During the rotation, the air pump is controlled to complete the dispensing work of the dispensing module on the needle. The overall operation is more convenient and the work efficiency is improved. After the dispensing is completed, the ultraviolet lamp 9 is turned on to accelerate the curing of the ink, prevent the ink from falling off, ensure the ink coating efficiency, and thus ensure product quality.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
