Description

Technical Field

[0001] The present application relates to the technical field of automatic ophthalmometers, and in particular to a fully automatic computer ophthalmometer. Background Art

[0002] The fully automatic computer optometry device can use a microprocessor and fast image processing technology to complete the measurement of the eye's refractive state in a short time, which greatly improves the efficiency compared to traditional optometry methods.

[0003] In the related technology, the instrument usually includes a fixed support base for supporting the whole parts, an optical mechanism for detecting the eyes, a mobile mechanism responsible for automatic alignment according to the eye position and eye movement, a data processing mechanism for analyzing and calculating and feeding back eye information, a display and operation mechanism for displaying the optometry results and for the optometrist to operate, and an auxiliary mechanism for the patient to locate the eye position. The instrument can automatically identify the state of the eyeball and locate it, and the optometrist can complete the optometry process with simple operations, reducing the errors and tediousness of manual operations.

[0004] In view of the above-mentioned related technologies, the moving mechanism of the ophthalmometer usually uses an electric slide with strong responsiveness. When the guide rails, lead screws, sliders and other components of the electric slide are subjected to excessive force in some parts, resulting in uneven load distribution, the slide will move unsteadily and produce abnormal sounds or even noise. The noise of the slide is usually accompanied by vibration, which may be transmitted to other components of the ophthalmometer such as the lens or reflector of the optical mechanism and the sensor of the data processing mechanism, interfering with the normal operation of the instrument and making the measurement data unstable. Noise or abnormal sounds may also reduce the patient's cooperation during the optometry process, making it impossible to maintain correct gaze or a stable head position, resulting in deviations in the measurement results and affecting the accurate measurement of the refractive power. Summary of the invention

[0005] In order to improve the situation where the moving mechanism is prone to produce abnormal sounds or noises, reduce interference to patients, and improve the accuracy of refractive power measurement results, the present application provides a fully automatic computer optometry device.

[0006] The fully automatic computer optometry device provided in this application adopts the following technical solution: A fully automatic computer optometry device, comprising a support base for supporting other components, an optical path platform mechanism for detecting eyes, a silent moving mechanism for driving the optical path platform mechanism to move for alignment with the patient's eyes, a display operating mechanism for optometrists to operate, and an auxiliary mechanism for patients to position their eyes; The silent moving mechanism includes an XY axis moving mechanism and a Z axis lifting mechanism, the supporting base includes a base bottom plate and a base shell fixedly connected to the base bottom plate, the Z axis lifting mechanism is installed on the base bottom plate and located in the base shell, the XY axis moving mechanism is installed above the Z axis lifting mechanism, the optical path platform mechanism has an optical path mounting bottom plate, and the optical path mounting bottom plate is fixedly connected to the XY axis moving mechanism; The XY axis moving mechanism is sleeved with a middle shell on its exterior, and an adjustment gap is reserved between the inner wall of the middle shell and the outer wall of the base shell for the XY axis moving mechanism to move.

[0007] By adopting the above technical solution and setting up a silent moving mechanism, the problem of abnormal sound and noise caused by uneven movement of the traditional electric slide due to uneven load distribution is specifically solved. The silent moving mechanism effectively reduces the noise and abnormal sound during the optometry process, avoiding the situation where the patient's cooperation is reduced due to these interference factors. Patients can undergo optometry in a relatively quiet environment, and it is easier to maintain correct gaze and stable head position, thereby creating good conditions for accurate measurement of refractive power. The connection method of the XY axis moving mechanism and the Z axis lifting mechanism of the silent moving mechanism with the support base and the optical path platform mechanism not only ensures that the optical path platform mechanism can accurately detect the patient's eyes, but also facilitates the coordinated work of various components. The XY axis moving mechanism is externally sleeved with a middle shell, and an adjustment gap is left between the middle shell and the base shell, which provides a certain space margin for the movement of the XY axis moving mechanism, making it more flexible and free during the movement process, optimizing the movement performance of the moving mechanism, and also helping to reduce abnormal situations that may be caused by limited movement.

[0008] Further, the XY axis moving mechanism includes a translation base, an X axis slider, a Y axis slider, an X axis driving assembly for cooperating with the X axis slider, and a Y axis driving assembly for cooperating with the Y axis slider, and the driving directions of the X axis driving assembly and the Y axis driving assembly are perpendicular to each other; The translation base is fixedly connected to the top of the Z-axis lifting mechanism, a transverse guide rod for the X-axis slider to slide is installed on the translation base, the X-axis slider is slidably installed on the transverse guide rod, a longitudinal guide rod for the Y-axis slider to slide is installed on the X-axis slider, the Y-axis slider is slidably installed on the longitudinal guide rod, and the Y-axis slider is integrally connected to a top side connection block for connecting the optical path installation base plate at the top; The X-axis slider is provided with a first shock absorbing assembly for cooperating with the X-axis driving assembly, and the Y-axis slider is provided with a second shock absorbing assembly for cooperating with the Y-axis driving assembly.

[0009] By adopting the above technical solution, the driving directions of the X-axis driving assembly and the Y-axis driving assembly are perpendicular to each other, and the movement of the XY-axis moving mechanism in the plane can be accurately controlled, so that the optical path platform mechanism can be accurately moved to the position corresponding to the patient's eyes for detection, and the accuracy of the alignment is improved. The X-axis slider can slide along the horizontal guide rod, and the Y-axis slider can slide on the longitudinal guide rod. The double-layer slider makes the movement of the optical path platform mechanism in the plane more flexible and diverse, and improves the applicability of the optometry device. A first shock-absorbing assembly is set on the X-axis slider to cooperate with the X-axis driving assembly, and a second shock-absorbing assembly is set on the Y-axis slider to cooperate with the Y-axis driving assembly. The vibration generated when the driving assembly is working will be effectively absorbed and buffered by the corresponding shock-absorbing assembly, avoiding the vibration from being directly transmitted to the optical path platform mechanism and other components of the entire optometry device, reducing the noise and abnormal sound that may be caused by vibration.

[0010] Further, two through holes are symmetrically provided on both sides of the X-axis slider and on both sides of the Y-axis slider along the moving direction, and linear bearing assemblies are provided in the through holes. The X-axis slider is slidably connected to the transverse guide rod through the linear bearing assembly, and the Y-axis slider is slidably connected to the longitudinal guide rod through the linear bearing assembly. The linear bearing assembly includes an elastic spacer sleeved on the outer wall of the transverse guide rod / the longitudinal guide rod and at least two linear bearings, the two linear bearings are symmetrically abutted against the two ends of the elastic spacer, the X-axis slider / the Y-axis slider is provided with a fixing part for fixing the linear bearing, and the X-axis slider and the Y-axis slider are respectively provided with mounting blind holes at both ends for inserting the fixing parts, and the mounting blind holes are located at adjacent positions of the through holes.

[0011] By adopting the above technical solution, a linear bearing assembly is set between the X-axis slider and the transverse guide rod, and between the Y-axis slider and the longitudinal guide rod, and the friction coefficient between the slider and the guide rod is greatly reduced by utilizing the characteristics of the linear bearing itself. This allows the X-axis slider to slide on the transverse guide rod and the Y-axis slider to slide on the longitudinal guide rod very smoothly, ensuring the smoothness of the XY-axis moving mechanism moving in the plane, thereby ensuring that the optical path platform mechanism can accurately align with the patient's eyes, and improving the efficiency and accuracy of the optometry operation. The elastic spacer in the linear bearing assembly and at least two symmetrically arranged linear bearings enable the load pressure borne by the slider when it slides on the guide rod to be more evenly distributed on each component. When the slider is subjected to external force during movement, the elastic spacer can play a role in buffering and regulation, avoiding deformation or damage of components caused by excessive local pressure. At the same time, the linear bearing can better share the pressure and maintain a stable contact relationship between the slider and the guide rod, thereby enhancing the structural stability of the entire XY-axis moving mechanism and providing support for the long-term stable operation of the optometry device. The elastic spacer also has a shock-absorbing function during the movement of the slider. When the slider vibrates slightly due to the driving component, the elastic spacer can absorb and buffer part of the vibration energy, reducing the vibration transmitted to the guide rod and other parts of the entire optometry device through the slider. At the same time, the linear bearing assembly makes the slider move more smoothly, and also avoids additional noise caused by jamming or uneven friction to a certain extent, further creating a quiet optometry environment, which is conducive to patients staying relaxed during the optometry process and improving cooperation.

[0012] Furthermore, U-shaped grooves for the two ends of the transverse guide rod to be inserted into are symmetrically opened on both sides of the translation base, and two fixing screws are symmetrically passed through the transverse guide rod near the two ends, and the positions of the fixing screws correspond to the U-shaped grooves up and down.

[0013] By adopting the above technical solution, the U-shaped grooves symmetrically opened on both sides of the translation base provide a precise installation position for the transverse guide rod, so that the transverse guide rod can be accurately inserted into it. The two fixing screws are symmetrically inserted near the two ends of the transverse guide rod, and their positions correspond to the upper and lower U-shaped grooves. By tightening the fixing screws, the transverse guide rod can be firmly fixed in the U-shaped groove. This connection method effectively ensures the stability of the connection between the transverse guide rod and the translation base, so that the transverse guide rod will not easily displace or loosen when subjected to the sliding of the X-axis slider and related external forces, providing a stable and reliable support foundation for the smooth sliding of the X-axis slider on it. The matching design of the U-shaped groove and the fixing screw makes the installation process of the transverse guide rod relatively simple. During assembly, it is only necessary to accurately insert the two ends of the transverse guide rod into the U-shaped groove, and then insert the fixing screws and tighten them to complete the installation. The operation is relatively intuitive and easy to use, which reduces the difficulty of installation and improves assembly efficiency.

[0014] Further, the X-axis driving assembly includes a driving motor mounted on the translation base, a screw rod provided on the driving motor, and a high-precision nut provided on one end of the screw rod away from the driving motor, the high-precision nut and the screw rod are threadedly matched, and the X-axis slider is fixedly connected to a mounting plate at the lower side, and the mounting plate is provided with a through hole for the screw rod to pass through; The first shock absorbing assembly is installed on a side of the mounting vertical plate away from the driving motor, and a flexible shock absorbing composite sheet is provided on a side of the driving motor close to the screw rod.

[0015] By adopting the above technical solution, the flexible shock-absorbing assembly sheet arranged on the side of the drive motor close to the screw rod can effectively absorb and buffer the vibration generated by the drive motor during operation. When the motor is running, it is inevitable to generate certain vibrations. If these vibrations are directly transmitted to the screw rod, the X-axis slider and other components of the entire optometry device, they may cause noise and affect the stability and measurement accuracy of the components. The flexible shock-absorbing assembly sheet can block most of the vibrations near the motor to prevent them from spreading outward, thereby creating a relatively quiet working environment and improving the stability of the instrument. The first shock-absorbing assembly installed on the side of the mounting plate away from the drive motor can also play a good role in absorbing and buffering the vibrations that may be generated by the rotation of the screw rod to drive the X-axis slider to move. When the X-axis slider moves under the drive of the screw rod, some vibrations may be generated due to factors such as the thread fit between the screw rod and the high-precision nut. The first shock-absorbing assembly can effectively process these vibrations to prevent them from being transmitted to the optical path platform mechanism and other components, further ensuring the smooth operation of the instrument and reducing the possibility of noise generation.

[0016] Further, the first shock-absorbing assembly includes a primary shock-absorbing column, a secondary shock-absorbing column, a shock-absorbing column pressure plate and a connecting piece, one end of the primary shock-absorbing column vertically passes through and is fixedly connected to the mounting vertical plate, one end of the primary shock-absorbing column away from the mounting vertical plate abuts against the high-precision nut, one end of the secondary shock-absorbing column passes through the high-precision nut and is fixedly connected to the end of the primary shock-absorbing column, and the shock-absorbing column pressure plate is fixedly connected to one end of the secondary shock-absorbing column away from the connection with the primary shock-absorbing column through the connecting piece; The shock-absorbing column pressure plate is provided with a sliding through hole for the high-precision nut to pass through and slide, and the shock-absorbing column pressure plate is fixedly connected to the mounting vertical plate.

[0017] By adopting the above technical solution, the first shock-absorbing component adopts a multi-stage structure of a primary shock-absorbing column and a secondary shock-absorbing column. When the screw rotates to drive the high-precision nut to move, and then drives the X-axis slider to move, if vibration is generated, the primary shock-absorbing column can firstly absorb and buffer the vibration transmitted by the high-precision nut. Since one end of the primary shock-absorbing column is fixedly connected to the mounting plate, and the other end is in contact with the high-precision nut, it can effectively block part of the vibration from propagating to the mounting plate and other parts of the X-axis slider. The secondary shock-absorbing column further extends the shock-absorbing path, one end of which passes through the high-precision nut and is connected to the end of the primary shock-absorbing column. It can absorb and process the vibration that remains after being processed by the primary shock-absorbing column again. Through the synergistic effect of the two-stage shock-absorbing column, the vibration reduction effect is enhanced, and the impact of vibration on the entire optometry device is effectively reduced.

[0018] Furthermore, the flexible shock-absorbing assembly sheet includes two rigid connection plates for fixedly connecting to the driving motor, a soft shock-absorbing pad is fixedly connected between the two rigid connection plates, and both the rigid connection plate and the soft shock-absorbing pad have round holes for the screw rod to pass through.

[0019] By adopting the above technical solution, the flexible shock-absorbing composite sheet is composed of two rigid connecting plates and a soft shock-absorbing pad sandwiched in the middle. When the drive motor generates vibration during operation, the rigid connecting plate can be firmly connected to the drive motor as a supporting structure, while the soft shock-absorbing pad can give full play to its shock-absorbing characteristics and effectively absorb and buffer the vibration generated by the motor. The soft shock-absorbing pad has good elasticity and damping performance. It can convert the energy of motor vibration into other forms of energy such as heat energy, thereby reducing the transmission of vibration to the screw rod and other components, and effectively reducing the noise that may be caused by motor vibration. Both the rigid connecting plate and the soft shock-absorbing pad are provided with round holes for the screw rod to pass through, ensuring that the screw rod can pass normally through the flexible shock-absorbing composite sheet under the drive of the drive motor. While achieving the shock-absorbing function, it will not hinder the transmission of the screw rod.

[0020] Furthermore, the Z-axis lifting mechanism includes a lower bearing seat fixedly connected to the bottom plate of the base, a lifting screw rod perpendicular to the lower bearing seat, a stand slider sleeved and threadedly connected to the lifting screw rod, an upper bearing seat for connecting the upper end of the lifting screw rod is provided above the stand slider, and the bottom plate base is provided with a lifting drive assembly for driving the lifting screw rod; The base bottom plate is vertically arranged and fixedly connected with a lower frame, and the lower frame is provided with a waist-shaped slide groove along the height direction for the frame slider to pass through and slide, and the frame slider protrudes from the end surface of the waist-shaped slide groove and is fixedly connected with an upper frame, and the translation base is fixedly connected to the top side of the upper frame.

[0021] By adopting the above technical solution, the lifting drive assembly drives the lifting screw to rotate, and the stand slider threadedly connected to the lifting screw can convert the rotational motion of the screw into a linear lifting motion. The lifting and lowering of the stand slider in the Z-axis direction is controlled by the screw transmission, so as to achieve height adjustment of the translation base and the XY-axis moving mechanism, optical path platform mechanism, etc. connected thereto, so that the optical path platform mechanism can be accurately adjusted to a suitable position in the vertical direction with respect to the patient's eyes for detection. The waist-shaped slide groove opened along the height direction of the lower stand provides a guide path for the stand slider, and the stand slider is inserted and slides therein. The waist-shaped slide groove limits the movement direction of the stand slider, so that it can only slide smoothly in the vertical direction, avoiding the stand slider from deflecting, shaking, and other unstable conditions during the lifting process.

[0022] Furthermore, the lifting drive assembly includes a driving gear rotatably connected to the bottom plate of the base, a synchronous driven wheel rotatably connected to the lower bearing seat and fixedly connected to the lower end of the lifting screw rod, a synchronous belt tensioned between the driving gear and the synchronous driven wheel, and a lifting drive motor for driving the driving gear, and a stepper motor frame for mounting the lifting drive motor is fixedly connected to the bottom plate of the base.

[0023] By adopting the above technical solution, the driving gear, the synchronous driven wheel and the synchronous belt tensioned between them form a transmission system. The driving gear is driven to rotate by the lifting drive motor, and its rotation is transmitted to the synchronous driven wheel through the synchronous belt, which in turn drives the lifting screw to rotate, thereby realizing precise lifting and lowering control of the vertical frame slider in the Z-axis direction. The synchronous belt plays a buffering and connecting role in the transmission process. It can not only effectively transmit power and smoothly transmit the power of the driving gear to the synchronous driven wheel, but also absorb and buffer the vibration and impact that may occur during the transmission process to a certain extent, maintain the stability of the entire transmission system, and ensure that the lifting and lowering process of the vertical frame slider is smooth and continuous.

[0024] Furthermore, the auxiliary mechanism is installed on one side of the base shell, and the base shell is provided with a result printing mechanism for cooperating with the display operation mechanism on the opposite side of the auxiliary mechanism. The display operation mechanism is arranged above the optical path platform mechanism and is electrically connected to the result printing mechanism.

[0025] By adopting the above technical solution, the auxiliary mechanism is installed on one side of the base shell, which is convenient for patients to quickly locate the eye position during the optometry process and cooperate with the optometry operation. The display operation mechanism is arranged above the optical path platform mechanism, which is convenient for the optometrist to perform operation control during the optometry test, such as starting the test program, adjusting the test parameters, etc., and can also view the relevant data and image information during the test in real time. The display operation mechanism is electrically connected to the result printing mechanism. After the optometry test is completed, the relevant test results can be transmitted from the display operation mechanism to the result printing mechanism, and the optometry results can be output in paper form.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the silent moving mechanism, the X-axis driving component and the Y-axis driving component of the XY-axis moving mechanism are set perpendicular to each other, and their movement in the plane is accurately controlled, so that the optical path platform mechanism can be accurately moved to the position corresponding to the patient's eyes for detection, thereby improving the accuracy of alignment. The Z-axis lifting mechanism can realize the precise height adjustment of the relevant components in the vertical direction, so that the optical path platform mechanism can cooperate with the patient's eyes for detection at a suitable height, and comprehensively guarantee the accuracy of the detection position in the optometry operation. The linear bearing assembly set between the X-axis slider and the horizontal guide rod, and the Y-axis slider and the longitudinal guide rod reduces the friction coefficient, ensures that the XY-axis moving mechanism moves smoothly in the plane, and then ensures the accurate alignment of the optical path platform mechanism and the patient's eyes, effectively improving the efficiency of the optometry operation; 2. The first shock-absorbing assembly on the X-axis slider cooperates with the X-axis drive assembly, the second shock-absorbing assembly on the Y-axis slider cooperates with the Y-axis drive assembly, and the flexible shock-absorbing assembly sheet arranged next to the drive motor can effectively absorb and buffer the vibration generated by each component during operation, and prevent the vibration from being transmitted to the optical path platform mechanism and other components, thereby reducing the noise and abnormal sound caused by vibration and creating a relatively quiet working environment. The elastic spacer and linear bearing in the linear bearing assembly can not only evenly distribute the load pressure on the slider and enhance the structural stability, but also absorb and buffer the vibration energy through the elastic spacer when the slider moves and generates slight vibration, further reducing noise, which is conducive to patients staying relaxed and improving cooperation; 3. For example, the translation base and the transverse guide rod are firmly connected through the U-shaped groove and the fixing screws to ensure the stability of the transverse guide rod and the smooth sliding of the X-axis slider. The various components of the XY-axis moving mechanism are tightly connected and reasonably arranged. The middle shell is set on the outside and an adjustment gap is left to optimize the movement performance. The various components of the Z-axis lifting mechanism are arranged in order, and the waist-shaped slide groove is used to provide guidance for the frame slider to ensure the smooth lifting process. The connection method between the various mechanisms of the overall device is reasonable, which not only ensures the accurate alignment detection of the optical path platform mechanism, but also facilitates the coordinated work of various components.

[0055] The implementation principle of a fully automatic computerized optometry device in the embodiment of the present application is as follows: the device is composed of a support base 1, an optical path platform mechanism 2, a silent moving mechanism 3, a display operation mechanism 4, and an auxiliary mechanism 5. The support base 1 supports other components, the optical path platform mechanism 2 detects the patient's eyes, the silent moving mechanism 3 makes the optical path platform mechanism 2 align with the eyes, the auxiliary mechanism 5 assists the patient in positioning, and the display operation mechanism 4 is operated by the optometrist and cooperates with the result printing mechanism 6.

[0056] The silent moving mechanism 3 includes an XY axis moving mechanism 31 and a Z axis lifting mechanism 32. In the Z axis lifting mechanism 32, the lifting drive assembly 327 drives the lifting screw 324 to rotate, so that the stand slider 323 threaded with the screw 3152 is lifted and lowered along the screw 3152. The waist-shaped slide groove 3211 of the lower stand 321 guides the stand slider 323, and the lifting guide rod 328 and the pressure spring 329 sleeved thereon ensure stability. In the XY axis moving mechanism 31, the X axis and Y axis driving assemblies 316 are perpendicular to each other, respectively driving the X axis slider 313 to slide on the translation base 312 and the Y axis slider 314 on the X axis slider 313, so as to realize the plane movement of the optical path platform mechanism 2. The horizontal and vertical guide rods 3131 are firmly connected to the slider through the U-shaped groove 3122 and the fixing screw 3123. The linear bearing assemblies 317 on both sides of the slider reduce friction and ensure smooth sliding.

[0057] In terms of vibration reduction and noise reduction, the first vibration reduction assembly 3136 of the X-axis slider and the second vibration reduction assembly 3142 of the Y-axis slider 314 can absorb the vibration generated by the movement of the slider. The flexible vibration reduction assembly 318 next to the drive motor 3151 can absorb the motor vibration. The elastic spacer 3171 in the linear bearing assembly 317 also has a vibration reduction effect, reducing vibration transmission and noise.

[0058] The display operation mechanism 4 facilitates the optometrist to operate and view data. After the optometry is completed, the result can be transmitted from the display operation mechanism 4 to the result printing mechanism 6 for printing, thereby realizing the output of the result. The various components work together to ensure the accuracy, efficiency and convenience of optometry.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
