Description

[Technical Field]

[0001] This utility model relates to the field of optical material processing technology, and in particular to an automatic and uniform mixing device for optical inks. [Background Technology]

[0002] In the manufacturing process of modern optical lenses, optical inks, as an important functional material, are widely used for matte finishing of lens surfaces. Their main function is to reduce reflection and stray light on the lens surface by blocking and absorbing light, thereby improving the lens's optical performance. However, the performance of optical inks is closely related to their uniformity. Since optical inks are typically composed of multiple components such as resins, solvents, and pigments, and these components have significant differences in specific gravity, they are prone to layering during prolonged standing or storage. This layering leads to decreased ink adhesion and weakened covering power, thus affecting the matte finish and overall quality of the lens.

[0003] To address this issue, traditional processes typically rely on manual stirring to mix the layered inks. In practice, workers manually stir the ink using tools such as copper rods to restore its uniformity. However, this manual stirring method has several drawbacks: First, the process is cumbersome, time-consuming, and labor-intensive, increasing production costs; second, because the force and speed of manual stirring are difficult to control precisely, the ink often fails to achieve a fully uniform mixture, leading to inconsistent quality in subsequent lens production; furthermore, manual operation can introduce air bubbles or impurities, further affecting the ink's performance. [Utility Model Content]

[0004] The purpose of this invention is to provide an automatic and uniform mixing device for optical inks, which aims to solve the problems of uneven mixing, low efficiency and unstable quality caused by ink stratification in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic optical ink mixing and homogenization device includes a support device, a drive mechanism fixedly connected to the support device, a carrier device connected to the output end of the drive mechanism, and an ink container detachably connected to the carrier device. When the drive mechanism is running, the optical ink in the ink container can be automatically mixed.

[0007] The optical ink automatic mixing and homogenizing device described above further includes a control device disposed on the support device for adjusting the rotation speed, the control device being electrically connected to the drive mechanism.

[0008] As described above, an automatic mixing and homogenizing device for optical inks includes a support device comprising a base, support plates on both sides of the base, and a mounting plate between the two support plates. The mounting plate is inclined relative to the base. A drive mechanism is fixed on the mounting plate, and the output end of the drive mechanism passes through the mounting plate and is connected to the bearing device.

[0009] As described above, the optical ink automatic mixing and homogenization device includes a drive mechanism comprising a drive motor connected to a reducer. The reducer includes an output shaft passing through the mounting plate, and a connector is sleeved and fixed on the output shaft. One end of the connector is fixed to the bearing device.

[0010] As described above, in an automatic optical ink mixing and homogenization device, the bottom surface of the ink container is parallel to the end face of the mounting plate, and the mounting plate forms an angle α with the horizontal plane, wherein the value of the angle α ranges from 25° to 55°.

[0011] In the optical ink automatic mixing and homogenization device described above, the included angle α ranges from 35° to 45°, and at this time, the output shaft speed n of the reducer satisfies 15 rpm ≤ n ≤ 20 rpm.

[0012] As described above, in an automatic optical ink mixing and homogenization device, the carrier device is a box structure that matches the shape of the ink container into which it can be placed. The fitting gap between the inner wall of the carrier device and the outer wall of the ink container is h, and the value range of the fitting gap h is 0.3mm-1mm.

[0013] In the aforementioned automatic mixing and homogenizing device for optical inks, the fitting gap h ranges from 0.5mm to 1mm, and a shock-absorbing layer is provided between the inner wall of the carrier device and the outer wall of the ink container.

[0014] As described above, an automatic mixing and homogenizing device for optical inks has an anti-tipping counterweight on its base.

[0015] As described above, the optical ink automatic mixing and homogenization device has a base that can be fixed to other structural surfaces.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This utility model achieves automatic mixing of optical inks by setting up a support device, a drive mechanism, a bearing device, and a detachably connected ink container. This solves the problems of cumbersome, time-consuming, and labor-intensive traditional manual stirring operations. In addition, it avoids the problem of air bubbles or impurities that may be introduced by manual operation, which may affect the performance of the ink. This improves the ink mixing efficiency and reduces production costs.

[0018] 2. By setting an adjustable speed control device on the support device and electrically connecting it to the drive mechanism, the problem of insufficient ink mixing and unstable lens production quality caused by the difficulty in accurately controlling the stirring force and speed by manual stirring is solved. It has the effect of accurately controlling the mixing parameters and ensuring stable lens production quality. [Attached Image Description]

Detailed Implementation Methods

[0026] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0027] In the manufacturing process of modern optical lenses, optical inks, as black inks used to achieve the lens's anti-reflective properties, play a crucial role. However, due to the differences in the proportions of the resins, solvents, and pigments used in optical inks, the different components within the ink will gradually separate after prolonged standing. This separation phenomenon has a significant adverse impact on the quality of the ink, such as causing a substantial decrease in adhesion, making it unable to firmly adhere to the lens surface; at the same time, the ink's hiding power will also decrease, making it difficult to effectively achieve the lens's anti-reflective effect.

[0028] In the past, to restore the layered ink to a uniform state, operators would typically stir the ink with a copper rod before use and then pour it out for further preparation. However, this traditional stirring method has many drawbacks. Not only is the process cumbersome and time-consuming for operators, but due to the limitations of copper rod stirring, it is difficult to achieve a fully uniform mixture, which in turn affects the quality of subsequent lens production.

[0029] To resolve the above issues, please refer to Figures 1 to 6 This embodiment provides an automatic optical ink mixing and homogenization device, including a support device 1, a drive mechanism 2 fixedly connected to the support device 1, a carrier device 3 connected to the output end of the drive mechanism 2, and an ink container 4 detachably connected to the carrier device 3. When the drive mechanism 2 is running, the optical ink in the ink container 4 can be automatically mixed.

[0030] In this embodiment, the support device 1 can adopt a frame structure made of metal or high-strength polymer material. The drive mechanism 2 is installed and fixed on the support device 1 and can include, but is not limited to, a stepper motor, a servo motor, or other drive motors. Its output end is connected to the bearing device 3 through a coupling, so that the bearing device 3 rotates synchronously with it.

[0031] Optionally, in some embodiments, the carrier device 3 may include a detachable fixing structure, such as a snap-fit, gripper, sleeve or other possible quick-connect fitting, for mounting the ink container 4.

[0032] The ink container 4 can be a closed or semi-closed container adapted to the carrier device, and its interior can be provided with a flow guiding structure such as a spiral groove or a baffle.

[0033] When the drive mechanism 2 is started, the bearing device 3 rotates at a constant speed, simultaneously driving the ink container 4 to rotate at a predetermined speed. Under the action of centrifugal force, the optical ink in the ink container 4 continuously tumbles and mixes, effectively avoiding ink quality problems caused by uneven manual stirring. This achieves automatic, efficient, and uniform mixing of optical ink, providing reliable ink raw materials for the subsequent production of optical lenses.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the automatic optical ink mixing and homogenizing device also includes a control device 5 disposed on the support device 1 for adjusting the rotation speed, the control device 5 being electrically connected to the drive mechanism 2.

[0035] In this embodiment, the control device 5 can be a commercially available PLC controller. This controller can be mounted on one side of the support device 1 using fasteners to ensure a stable installation. The control device 5 can be equipped with an operation panel, a digital display screen, and operation buttons. The operator can input the desired rotational speed using the operation buttons, and the digital display screen will show the currently set rotational speed and the actual operating speed of the drive mechanism 2 in real time.

[0036] The control device 5 and the drive mechanism 2 are electrically connected via a cable. Preferably, a shielded cable can be used to prevent external electromagnetic interference and ensure the stability of signal transmission. After the operator sets the speed on the control device 5, the control device 5 will output a corresponding electrical signal to the drive mechanism 2 according to the set value. The drive mechanism 2 will adjust the speed according to the received signal, thereby achieving precise control of the speed of the bearing device 3.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the support device 1 includes a base 11, with support plates 12 respectively provided on both sides of the base 11, and a mounting plate 13 provided between the two support plates 12. The mounting plate 13 is inclined relative to the base, the drive mechanism 2 is fixed on the mounting plate 13, and the output end of the drive mechanism 2 passes through the mounting plate 13 and is connected to the bearing device 3.

[0038] Specifically, in this embodiment, the base 11 preferably adopts a rectangular frame structure made of steel plate. Optionally, in some embodiments, anti-slip pads can be provided at the bottom of the base 11 to enhance the stability of the equipment. The support plates 12 are vertically fixed to both sides of the base 11 by welding, bolting, or other means, and are symmetrically distributed. The mounting plate 13 is inclined between the two support plates 12, forming a triangular support structure with the base 11. The inclination angle is set according to actual needs. This triangular support structure makes the transmission of driving torque more stable and reduces the vibration amplitude during device operation. The drive mechanism 2 can be fixed to one side of the mounting plate 13 by bolts. Its output end passes through the preset through hole of the mounting plate 13 and is connected to the bearing device 3. In addition, the inclined design of the mounting plate 13 makes the output end of the drive mechanism 2 form a specific angle with the horizontal plane. When the bearing device 3 rotates, the fluid in the ink container 4 forms a multi-directional flow path under the combined action of centrifugal force and gravity, enhancing the mixing effect.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the drive mechanism 2 includes a drive motor 21, the drive motor 21 is connected to a reducer 22, the reducer 22 includes an output shaft 221 that passes vertically through the mounting plate 13, the output shaft 221 is fitted with a connector 222, and one end of the connector 222 is fixed to the bearing device 3.

[0040] In this embodiment, the reducer 22 is fixed to the side end face of the mounting plate 13 on one side. Its output shaft 221 passes vertically through the through hole of the mounting plate 13, and a connector 222 is sleeved at the end of the output shaft 221. It is fastened to the bearing device 3 by means of a threaded or keyway structure. The power of the drive motor 21 is reduced in speed and increased in torque by the reducer 22, and then transmitted to the connector 222 through the output shaft 221, driving the bearing device 3 to rotate smoothly. The reduction ratio between the reducer 22 and the drive motor 21 can be selected according to the ink viscosity requirements to ensure low-speed, high-torque output to maintain mixing stability.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom surface of the ink container 4 is parallel to the end face of the mounting plate 13, and the mounting plate 13 forms an angle α with the horizontal plane, the value of which is in the range of 25°-55°.

[0042] In this embodiment, since the bottom surface of the ink container 4 is parallel to the end surface of the mounting plate 13, when the mounting plate 13 forms an angle α with the horizontal plane, the ink container 4 will also form the same angle α with the horizontal plane. Within the angle range of 25°-55°, under the combined action of centrifugal force and gravitational force, the ink can form a more complex flow trajectory within the ink container, promoting full contact and mixing between different components in the ink, improving the uniformity of optical ink mixing, and ensuring the quality of the ink.

[0043] Specifically, when the tilt angle α of the mounting plate 13 is relatively large, the fluid in the ink container 4 forms a stronger axial flow along the tilt direction under the action of centrifugal force; when the angle is small, the proportion of radial flow increases. It should be noted that the specific setting of the tilt angle α depends on the viscosity of the optical ink.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation, the included angle α is in the range of 35°-45°, and at this time the output shaft 221 speed n of the reducer 22 satisfies 15 rpm ≤ n ≤ 20 rpm.

[0045] When the included angle α is between 35° and 45° and the rotation speed n satisfies 15 rpm ≤ n ≤ 20 rpm, the optical ink achieves a good mixing effect in the ink container 4.

[0046] More preferably, when the included angle α is 45° and n is 18 rpm, the fluid in the ink container 4 forms a stable laminar-turbulent alternating state. At this tilt angle, the fluid generates a spiral upward motion in the axial direction; and the low rotation speed ensures that the ink is fully sheared and dispersed under the action of centrifugal force, while avoiding the generation of bubbles.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the supporting device 3 is a box structure that matches the shape of the ink container 4 into which it can be placed, and the fitting gap between the inner wall of the supporting device 3 and the outer wall of the ink container 4 is h, with the value of the fitting gap h ranging from 0.3mm to 1mm.

[0048] In this embodiment, the carrier device 3 adopts a box body that matches the shape of the ink container 4, such as a cylindrical or square cavity. Furthermore, to ensure that the carrier device 3 can easily insert and remove the ink container 4 while effectively limiting the shaking of the ink container 4 during device operation and ensuring the stability of the mixing process, a fitting gap h exists between the inner wall of the carrier device 3 and the outer wall of the ink container 4. A fitting gap h of 0.3mm-1mm can prevent jamming caused by thermal expansion or processing errors, and can also suppress turbulent disturbance of the ink at the gap during mixing, reducing air bubble entrainment.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the value of the fitting gap h is in the range of 0.5mm-1mm, and a shock-absorbing layer is also provided between the inner wall of the bearing device 3 and the outer wall of the ink container 4.

[0050] In this embodiment, when the fitting clearance h is in the range of 0.5mm-1mm, a damping layer is bonded to the inner wall of the bearing device 3 or the outer wall of the ink container 4. The damping layer material can be elastic damping materials such as silicone or polyurethane, which can absorb the high-frequency micro-vibrations when the ink container 4 rotates, and can elastically deform to adapt to the dimensional tolerance within the gap range of 0.5-1mm, so as to reduce the noise during equipment operation and reduce the rigid collision between the outer wall of the ink container 4 and the bearing device 3.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, the base 11 is provided with an anti-overturning counterweight device (not shown in the figure). Specifically, a counterweight mounting groove can be provided at the bottom of the base 11, and a detachable counterweight block can be embedded in the groove to improve the anti-overturning performance of the device. In addition, the counterweight block can work in conjunction with the shock-absorbing layer mentioned above to absorb the reverse vibration energy generated by the rotating parts and improve the stability of the device.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the base 11 is also provided with an assembly part that can be fixed to other structural surfaces.

[0053] In this embodiment, standardized assembly parts (not shown in the figure) can be pre-set on the side and bottom surfaces of the base 11, including but not limited to:

[0054] Mechanical fixing interfaces, such as through-hole arrays or T-slots;

[0055] Quick-locking structures, such as lever clamps or magnetic adsorption modules.

[0056] The assembly section is designed to adapt the device to different installation environments. Whether it is a horizontal workbench or a vertical wall or other structural surface, it can be fixed by the assembly section, which greatly expands the application scenarios of the device.

[0057] Working principle of this utility model:

[0058] This invention proposes an automatic mixing and homogenizing device for optical inks. The device uses a drive mechanism to rotate the ink container, utilizing centrifugal force and gravity to induce a composite flow in the ink. The inclined mounting plate creates a three-dimensional turbulent flow field combining axial spiral flow and radial shear motion during rotation, preventing pigments, resins, and other components in the optical ink from forming stratified structures due to prolonged static contact, thus achieving uniform mixing.

[0059] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
