Description

Technical Field

[0001] This utility model relates to the field of waterproof sealing technology for buttons, and in particular to an assembly fixture for a waterproof sealing ring for an electric toothbrush handle button. Background Technology

[0002] An electric toothbrush is an oral hygiene device that uses electricity to drive the brush head to automatically vibrate, rotate, or sonicate, replacing or assisting manual brushing to more efficiently clean the tooth surface, gaps between teeth, and gingival sulcus. A waterproof sealing ring assembly fixture for the electric toothbrush handle button is a precision auxiliary tooling designed specifically for the electric toothbrush production process. Its core function is to achieve precise and efficient assembly of the waterproof sealing ring at the handle button area through standardized mechanical structure and positioning design, ensuring that the sealing ring fits tightly against the gap between the button and the handle, ultimately guaranteeing that the electric toothbrush button area achieves a waterproof rating. This also reduces manual assembly errors and improves production consistency.

[0003] An assembly fixture for a waterproof sealing ring for an electric toothbrush handle button uses mechanical transmission or pneumatic / hydraulic power systems to drive relevant components to assemble the sealing ring with the handle. However, the positioning effect of the existing circular fixing structure relies heavily on the precise fit between the outer circle of the button shell and the fixing groove of the fixture to fix the handle button shell. During the injection molding process, the button shell may have roundness deviations due to process fluctuations. The existing technology uses a contouring structure to compensate for the positional offset caused by roundness deviations through multi-dimensional positioning. Correspondingly, raised positioning pins or fitting slots are set in the contouring fixing cavity to ensure that the button shell is always in the preset precise position during assembly. However, the contouring fixture is integrally molded and fixedly connected to the worktable, and can only be positioned and assembled for toothbrush button shells of specific shapes and sizes. When it is necessary to assemble toothbrush button shells of different models or designs, the entire fixture needs to be replaced, which increases production costs and reduces production efficiency. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an assembly fixture for waterproof sealing rings of electric toothbrush handle buttons. It aims to improve the existing technology where the contouring fixture is fixedly connected to the workbench, and when different models of shells need to be assembled, the entire fixture needs to be replaced, which increases production costs and reduces production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof sealing ring assembly fixture for an electric toothbrush handle button, comprising a sealing ring fixture, wherein a plurality of clamping mechanisms are fixedly connected to the middle of the sealing ring fixture, the clamping mechanisms being used to clamp the toothbrush button plate, and a pushing mechanism is installed on the right side of the sealing ring fixture, the pushing mechanism being used to smoothly push the toothbrush button shell; the clamping mechanism includes a semi-contouring chuck, the semi-contouring chuck being slidably connected to the middle of the sealing ring fixture, and a plurality of guide posts being slidably connected to adjacent sides of the plurality of semi-contouring chucks, wherein a limit plate is fixedly connected to the middle of the outer wall of each guide post, and a drive assembly is installed on adjacent sides of the plurality of limit plates.

[0006] As a further description of the above technical solution: The drive assembly includes a motor, each motor being fixedly connected inside the sealing ring fixture. Each motor's output end is fixedly connected to a rotating block. The outer walls of multiple rotating blocks are rotatably connected to adjacent sides of a limiting plate. Multiple moving plates are fixedly connected to the outer walls of each rotating block. The other end of each moving plate is rotatably connected to a driven plate. The adjacent ends of multiple driven plates are rotatably connected to the outer wall of a semi-contouring chuck.

[0007] As a further description of the above technical solution: The pushing mechanism includes an electric push rod, which is fixedly connected to the left side of the sealing ring fixture. The output end of the electric push rod is fixedly connected to a rod head, and a pulling column is rotatably connected inside the rod head. A pushing block is rotatably connected to the other end of the pulling column. A guide groove block is slidably connected to the outer wall of the pushing block. Multiple guide columns are slidably connected to both sides inside the guide groove block, and a pushing plate is fixedly connected to the front side of the guide columns.

[0008] As a further description of the above technical solution: The bottom of the clamping mechanism is equipped with a bottom rotating plate, and multiple laser detectors are fixedly connected to the top of the bottom rotating plate.

[0009] As a further description of the above technical solution: The right side of the sealing ring fixture is fixedly connected to an infeed chuck, and an infeed conveyor belt is installed at the bottom of the infeed chuck.

[0010] As a further description of the above technical solution: A controller is fixedly connected to the top left side of the sealing ring fixture, and a screen is installed on the front side of the outer wall of the controller.

[0011] As a further description of the above technical solution: The right side of the sealing ring fixture is fixedly connected to a delivery clamp, and the right side of the sealing ring fixture is fixedly connected to a delivery slide.

[0012] As a further description of the above technical solution: A quality inspection conveyor belt is installed on the left side of the shipping chute, and a pushing mechanism is installed on the rear side of the quality inspection conveyor belt.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the drive component pulls the semi-contouring chuck to slide inward under the limit of the guide post. Under the restriction of the limiting plate, the chucks on both sides retract to the minimum. The semi-contouring chuck of this clamping component can clamp and adapt to toothbrush button plates of different sizes, avoiding the problem of increased cost and reduced production efficiency caused by adjusting the fixture when assembling different models of button shells.

[0014] In this invention, the electric push rod starts and moves forward, driving the fixed rod head forward, which in turn pulls the pull column, causing the push block connected to it to move accordingly. Under the guidance of the guide block and the guide columns on both sides, the push plate moves forward stably. This structure achieves pushing by pulling the pull column, avoiding the problem of damage to the toothbrush button plate caused by direct ejection. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a waterproof sealing ring assembly fixture for an electric toothbrush handle button. The fixture includes a sealing ring fixture 1, with multiple clamping mechanisms 2 fixedly connected to the middle of the fixture 1. These clamping mechanisms 2 clamp the toothbrush button plate. A pushing mechanism 3 is installed on the right side of the sealing ring fixture 1, used to smoothly push the toothbrush button shell. Each clamping mechanism 2 includes a semi-contouring chuck 201 slidably connected to the middle of the sealing ring fixture 1. Multiple guide posts 202 are slidably connected to adjacent sides of the semi-contouring chucks 201. Limiting plates 203 are fixedly connected to the middle of the outer walls of each guide post 202. A drive assembly 204 is installed on adjacent sides of the multiple limiting plates 203. The drive assembly 204 includes a motor 2041, which is a miniature DC brushed geared motor. Its working principle relies on the stator permanent magnet to form a magnetic field, and current flows through the brushes and commutator into the rotor coil. Electromagnetic force drives the rotor to rotate, commutating the phase. The device ensures continuous rotation and consists of a DC brushed motor and a reduction mechanism. The motors 2041 are all fixedly connected inside the sealing ring fixture 1. The output end of the motors 2041 is fixedly connected to the rotating blocks 2042. The outer walls of multiple rotating blocks 2042 are rotatably connected to the inside of the limiting plate 203 on adjacent sides. Multiple moving plates 2043 are fixedly connected to the outer walls of the rotating blocks 2042. The other end of the moving plates 2043 is rotatably connected to the driven plates 2044. The adjacent ends of multiple driven plates 2044 are rotatably connected to the outer wall of the semi-contouring chuck 201. The bottom of the clamping mechanism 2 is equipped with a bottom rotating plate 5. The top of the bottom rotating plate 5 is fixedly connected to multiple laser detectors 4. The laser detectors 4 are of the LR-X series. The working principle of the LR-X series laser detectors is that they use green lasers and triangulation systems. The laser emitter emits laser light, which is reflected by the target object and received by the CMOS image sensor. The laser generator is driven by the power supply to detect the laser. Specifically, after the robotic arm lowers the toothbrush button plate that needs to be fitted with a sealing ring, the laser detector 4 sends a signal to start the motor 2041. After the motor 2041 starts, the rotating block 2042 fixed at its output end will rotate synchronously within the limiting plate 203. Driven by the rotating block 2042, the motion plate 2043 fixedly connected to it will pull the driven plate 2044 to move. As the driven plate 2044 is pulled, the semi-contouring chuck 201 will slide inward under the limiting action of the guide post 202, and under the restriction of the limiting plate 203, the semi-contouring chucks 201 on both sides will retract to their minimum state. Through this retraction clamping action, the semi-contouring chucks 201 of the clamping mechanism 2 can adapt to toothbrush button plates of different sizes. Subsequently, the bottom rotating plate 5 can rotate to switch angles. There is no need to adjust the entire fixture for assembling different models of toothbrush button shells, thereby avoiding the problem of increased costs and reduced production efficiency caused by frequent fixture adjustments.

[0019] Reference Figure 5 and Figure 6The pushing mechanism 3 includes an electric push rod 301, which is fixedly connected to the left side of the sealing ring fixture 1. The output end of the electric push rod 301 is fixedly connected to a rod head 302. The inside of the rod head 302 is rotatably connected to a pulling column 303. The other end of the pulling column 303 is rotatably connected to a pushing block 304. The outer wall of the pushing block 304 is slidably connected to a guide groove block 305. Multiple guide columns 306 are slidably connected to both sides inside the guide groove block 305. A pushing plate 307 is fixedly connected to the front side of the guide column 306. Specifically, when the toothbrush button shell with the sealing ring installed is conveyed to the front end of the push plate 307, the electric push rod 301 starts and moves forward. The electric push rod is a DT type electric push rod. Its working principle is that the DT type electric push rod uses an electric motor as a power source, which drives the lead screw and nut pair through the reduction gear to convert the rotational motion of the electric motor into linear motion. It consists of a drive motor, a reduction gear mechanism, a lead screw and nut pair, a limit device, and a push rod shell and connecting parts. The electric push rod 301 will drive the rod head 302 fixed to it to move forward synchronously, thereby pulling the rod. The pull column 303 connected to the head 302, when subjected to force, will drive the push block 304 connected to it to move. Under the trajectory constraint of the guide block 305 and the guiding action of the guide columns 306 on both sides, the push plate 307 can move forward stably, and finally push the toothbrush button shell to complete the subsequent process. This structure replaces the traditional direct push design with the indirect pushing method of the pull column 303, which can buffer the impact force during the pushing process and avoid damage to the toothbrush button plate due to improper control of the direct pushing force, thus ensuring the integrity of the product.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The sealing ring fixture 1 is fixedly connected to the right side of the infeed chuck 6, and the bottom of the infeed chuck 6 is equipped with an infeed conveyor belt 7. The top left side of the sealing ring fixture 1 is fixedly connected to the controller 8, and the front side of the outer wall of the controller 8 is equipped with a screen 9. The right side of the sealing ring fixture 1 is fixedly connected to the outfeed chuck 10, and the right side of the sealing ring fixture 1 is fixedly connected to the outfeed chuck 11. The left side of the outfeed chuck 11 is equipped with a quality inspection conveyor belt 12, and the rear side of the quality inspection conveyor belt 12 is equipped with a pushing mechanism 3. Specifically, when the controller 8 starts the overall fixture, the infeed chuck 6 will precisely clamp the toothbrush button plate from the infeed conveyor belt 7 and transfer it to the sealing ring fixture 1. After the sealing ring fixture 1 completes the sealing ring installation process of the toothbrush button plate, the outfeed chuck 10 will clamp the toothbrush button plate with the sealing ring installed and place it into the outfeed chute 11. Then, the toothbrush button plate will slide along the outfeed chute 11 to the rear of the quality inspection conveyor belt 12, and then be pushed to the next process by the pushing mechanism 3. The operating parameters of the entire production process can be viewed in real time through the screen 9, which makes it convenient for operators to monitor the operating status of the equipment, detect and deal with abnormalities in a timely manner, and ensure the stable and efficient operation of production.

[0021] Working principle: After the robotic arm lowers the toothbrush button plate that needs to be sealed, the laser detector 4 sends a signal to start the motor 2041. As the motor 2041 starts, the rotating block 2042 fixed to the output end of the motor 2041 rotates within the limiting plate 203. Under the movement of the rotating block 2042, the moving plate 2043 fixed to the rotating block 2042 pulls the driven plate 2044 to move. As the driven plate 2044 is pulled, the semi-contouring chuck 201 slides inward under the limit of the guide post 202. Under the restriction of the limiting plate 203, the semi-contouring chucks 201 on both sides retract to the minimum. With the clamping of the semi-contouring chucks 201 of the clamping mechanism 2, it can adapt to toothbrush button plates of different sizes, thereby preventing the problem of increasing the cost and reducing the production efficiency of the entire fixture when adjusting when assembling different models of toothbrush button shells. When the toothbrush button shell with the sealing ring installed reaches the front end of the push plate 307, the electric push rod 301 moves before starting. As the electric push rod 301 drives the fixed rod head 302 forward, it pulls the pull column 303, which in turn drives the push block 304 connected to the pull column 303. Under the guidance of the guide block 305 and the guide columns 306 on both sides, the push plate 307 is stably pushed. Because the push is achieved by the pull column 303, the toothbrush button plate is not damaged by being directly pushed out.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
