In practical applications, the water-absorbing sheet 2 can be detachably fixed on the carrier 1 in various ways according to requirements. In practical applications, the number of water-absorbent sheets 2 placed on the stage 1 and the number of water-absorbent sheets 2 covered on the contact lens A can be changed according to requirements, and the water-absorbent sheets 2 The material, size, etc. can be changed according to the needs. For example, the material of each water-absorbing sheet 2 can be, for example, dust-free cloth, fiber cloth, cotton cloth, nylon cloth, polyester fiber cloth, dust-free paper, or other materials that can absorb water. In one practical application, two water-absorbing sheets 2 may be provided on the stage 1 , and two water-absorbing sheets 2 may be provided on the cover of the contact lens A.

In practical applications, the water absorbing device 100 of the contact lens also includes a fixed frame 6, which is used to be sleeved around the carrier 1 to press against the two water absorbing sheets 2, so that the two absorbing sheets 2 The contact lens A between the bars 2 is squeezed by the two water-absorbing sheets 2 . In practical application, when the fixed frame body 6 is sleeved around the carrier 1, the contact lens A located between the two water-absorbent sheets 2 will be squeezed, and the inverted bowl shape will be squeezed into a flat shape. .

At least one contact lens A in the middle of each water-absorbent sheet 2.

In practical applications, the driving module 3 may include, for example, a push rod 31 , a driver 32 and an auxiliary component 33 . The driver 32 can control the push rod 31 to move toward or away from the stage 1 along an axis (ie, the Y-axis direction marked in FIG. 3 ). The pressing module 4 includes a pressing block 41 , and the pressing block 41 can be directly connected to the push rod 31 , or connected to the push rod 31 via the auxiliary component 33 . The auxiliary component 33 includes a sliding rail 331 , a sliding block 332 and at least two connecting rod components. The sliding block 332 can move along another axis on the sliding rail 331 . The two link members are respectively defined as a first link member 333A and a second link member 333B, the two ends of the first link member 333A are respectively connected with the push rod 31 and the slider 332, and the push rod 31 is It is connected to the slider 332 through the first link member 333A. The second link member 333B is connected to the first link member 333A (or the slider 332 ), and the second link member 333B is connected to the pressing block 41 .

The processing module 5 can control the actuator 32 to actuate to actuate the push rod 31, and the push rod 31 will link the first link member 333A to actuate, and the first link member 333A will drive the slider 332 to move, so that the slider 332 moves along the slide rail 331, and the second link member 333B will move with the slide block 332, and the pressing block 41 connected with the second link member 333B will be driven to move on the water-absorbent sheet 2 move. That is to say, after the driver 32 is actuated, it will drive the pressing block 41 on the water-absorbent sheet 2 through the push rod 31, the first link member 333A, the second link member 333B, the slider 332 and the slide rail 331. move.

When the pressing block 41 is driven to move on the water-absorbing sheet 2, the weight of the pressing block 41 itself will act on the contact lens A positioned between the two water-absorbing sheets 2, thereby, The liquid outside the contact lens A between the two water-absorbing sheets 2 can be sucked away by the two water-absorbing sheets 2, thereby achieving the effect of removing the liquid outside the contact lens A.

It is worth mentioning that, in the figure of this embodiment, the direction in which the push rod 31 is driven to move along the axis is opposite to the direction in which the slider 332 moves on the slide rail 331, and the two moving directions are parallel to each other ( That is, the push rod 31 moves along the +Y-axis direction in FIG. 3, while the second link member 333B and the pressing block 41 move along the-Y-axis direction in FIG. invisible The overall volume of the water absorbing device 100 of the glasses. In addition, through the design of the sliding block 332 and the sliding rail 331 of the auxiliary assembly 33, the pressing block 41 can be effectively moved along a fixed axis, thereby ensuring that the pressing block 41 moves along a predetermined path to resist Contact lens A placed between two water-absorbent sheets 2 is pressed.

In practice, the relevant personnel may determine the weight of the pressing block 41 and the movement of the pressing block 41 back and forth on the water-absorbent sheet 2 according to the type of contact lens A (such as different moisture content, different brands, different styles, etc.). frequency. For example, the relevant personnel may choose a relatively heavy pressure block 41 to move back and forth on the water-absorbent sheet 2 once, or the relevant personnel may select a relatively light weight pressure block 41 to move back and forth on the water-absorbent sheet 2 once. Sheet 2 goes back and forth more than 3 times.

In a preferred embodiment, relevant personnel may first use the water absorbing device 100 of the contact lens to test contact lenses with different water contents, so as to test the weight and weight of the pressure block 41 suitable for various contact lenses. 41 the times of moving back and forth on the water-absorbent sheet 2, and then the relevant personnel can pass the related results through related devices (such as keyboards, mice, various electronic devices or any input devices, etc.), with wired or wireless The method is transmitted to the processing module 5 to be stored as a contact lens processing information 71, and then the processing module 5 can control the driving module 3 according to the contact lens processing information 71, so that the pressing block 41 is in the shape of a water-absorbing sheet Object 2 moves back and forth for a preset number of times.

As shown in Figure 2, in one of the specific embodiments, the water absorbing device 100 of the contact lens can also include an input module 7, the input module 7 is electrically connected to the processing module 5, and the input module 7 is used for the user In order to generate the contact lens treatment information 71, the input module 7 can transmit the contact lens treatment information 71 to the processing module 5; wherein, the contact lens treatment information 71 includes at least the preset number of times.

For example, the input module 7 may include a plurality of operation buttons, and the processing module 5 and the input module 7 may be integrated into an operation device, or the input module 7 may be designed for a certain operation Virtual input boxes in software, etc.

As shown in Figures 3 and 4, in a preferred embodiment, the side of the pressing block 41 facing the water-absorbent sheet 2 may include two chamfered structures 411, and the two chamfered structures 411 are roughly located at the described At the two opposite ends of the pressing block 41, when the pressing block 41 is driven by the driving module 3 to move on the water-absorbing sheet 2, each chamfer structure 411 is squeezed and arranged on the two water-absorbing sheets. A contact lens between 2. Through the design of the two chamfer structures 411 , it can effectively prevent the contact lens A located between the two water-absorbing sheets 2 from being damaged by the pressing block 41 during the movement. That is to say, if the corners of the pressing block 41 do not have the design of the chamfer structure 411, in practice, the corners of the pressing block 41 will be relatively easy to occur, resulting in contact lenses located between the two water-absorbing sheets 2 A damage problem.

It should be noted that if the contact lens A located between the two water-absorbent sheets 2 is damaged, the moisture contained in the contact lens A will be easily absorbed by the water-absorbent sheets 2, thereby causing The measurement of the water content of the subsequent contact lens A was inaccurate.

According to the above, in practice, the weight of the pressing block 41 can be designed according to the material and water content of the contact lens A on the stage 1, so that the pressing block 41 is placed on the water-absorbent sheet 2 When moving, the contact lens A will not be excessively pressed, but only the water-absorbing sheet 2 absorbs the liquid outside the contact lens A. Conversely, if the weight of the pressing block 41 is improperly designed, after the pressing block 41 moves on the stage 1, the moisture inside the contact lens A may be squeezed due to excessive external force. There is a problem with contact lens A.

As shown in Figures 1 and 3, in practical applications, the pressing module 4 of the contact lens water absorbing device 100 may also include at least one counterweight unit 42, and the pressing block 41 may also include a counterweight container 412 , and the counterweight container 412 is used for accommodating the counterweight unit 42 with at least one preset weight.

More specifically, when the relevant personnel intend to use the water absorbing device 100 of the contact lens to remove the contact lens A with a relatively high water content (for example, 55%), or remove the contact lens A with a relatively low water content (for example, 38%), Relevant personnel can set the counterweight unit 42 with the same preset weight in the counterweight container 412 .

As shown in FIG. 2 , in practice, in order to avoid misplacement of the counterweight unit 42 by relevant personnel, the water absorbing device 100 of the contact lens may also include a sensor 8 for sensing the position of the pressing block 41 The weight of the counterweight unit 42, or the sensor 8 is used to sense the pressure block 41 and the counterweight unit 42 weight, the processing module 5 is electrically connected to the sensor 8 . For example, the sensor 8 can be various light sensors (Light Sensor), so as to sense the weight of the counterweight unit 42 provided by the pressing block 41; or, the sensor 8 can be a pressure sensor. The sensor is used to sense the weight of the counterweight unit 42 disposed in the counterweight slot 412 .

The processing module 5 can judge whether the weight of the counterweight unit 42 set in the counterweight container 412 conforms to a standard according to the contact lens processing information 71 and the sensing information 81 returned by the sensor 8. Preset weight. If the processing module 5 determines that the weight of the counterweight unit 42 disposed in the counterweight container 412 does not meet the preset weight, the processing module 5 sends a warning message 51 . In practice, the processing module 5 can, for example, transmit the warning information 51 to a related warning device, so as to remind the user that the current setting method of the counterweight unit 42 is wrong through sound, light beam, etc.; or, the processing module 5 It may be to control a display device (such as a variety of screens) to display the warning information 51, and the user can watch text content such as: the current weight of the counterweight unit 42 is incorrect, please reposition it, etc. on the display device.

As shown in FIGS. 3 and 4 , it is worth mentioning that the resisting block 41 is connected to the second link member 333B, and the resisting block 41 includes a first engaging structure 413 . The first engaging structure 413 is, for example, a through hole penetrating through the pressing block 41 , and the shape of the first engaging structure 413 may be similar to a T-shape.

The end of the second link member 333B includes a second engaging structure 333B1, the first engaging structure 413 is used to engage with the second engaging structure 333B1, and the first engaging structure 413 and the second engaging structure 413 engaged with each other The engaging structure 333B1 is only used to limit the movable range of the pressing block 41 relative to the second link member 333B on the axis, and the first engaging structure 413 and the second engaging structure 333B1 that are engaged with each other are not used to limit the pressing block. 41 relative to the range of movement of the second link member 333B in a longitudinal direction. The longitudinal direction is mutually perpendicular to the axis.

Specifically, the first engaging structure 413 and the second engaging structure 333B1 are used to limit the range of movement of the pressing block 41 and the second connecting rod member 333B in the X-axis coordinate direction and the Y-axis coordinate direction indicated in FIG. 3 , while the first engaging structure 413 and the second engaging structure 333B1 do not limit the pressure Block 41 and the second link member 333B in the range of movement in the Z-axis coordinate direction marked in FIG. In this way, the pressure block 41 and the counterweight unit 42 arranged on it can be more accurately controlled to apply to the contact lens A between the two water-absorbing sheets 2. force.

In practice, the time for the pressing block 41 to press the contact lens A located between the two water-absorbing sheets 2 will also affect whether the liquid located outside the contact lens A is removed. Specifically, if the time for the pressing block 41 to squeeze the water-absorbing sheet 2 is too long, the contact lens A may be damaged; otherwise, if the time for pressing the pressing block 41 to squeeze the water-absorbing sheet 2 is too short, Then the liquid located outside the contact lens A may not be sufficiently absorbed by the water-absorbent sheet 2 .

Therefore, in one of the embodiments, the water absorbing device 100 for contact lenses may further include at least one distance detection module 9 (as shown in FIGS. 1 to 3 ), and the distance detection module 9 is electrically connected to the processing module. 5. The processing module 5 can cooperate with the distance detection module 9 to detect the moving distance of the pressing block 41, and the distance detection module 9 can detect the position of the pressing block 41, and generate a Distance Detection Information 91. The distance detection module 9 can be, for example, various position sensors, but is not limited thereto. The processing module 5 can process the information 71 according to the contact lens, and cooperate with the distance detection information 91, so that the pressing block 41 is at least one predetermined position on the water-absorbent sheet 2 during the process of moving on the water-absorbent sheet 2 Stay for a predetermined time. In this embodiment, the contact lens treatment information 71 includes the predetermined time.

In other words, the relevant personnel can first use the water-absorbing device 100 of the contact lens to test various contact lenses A with different water contents, how much weight of the pressing block 41 is required, and the water-absorbing sheet 2 stays on it for a few seconds before it can be tested. Effectively remove the liquid located in the contact lens A, and establish the contact lens treatment information 71 accordingly.

According to the above, the applicant used the commercially available AVISION ^® Ou Comfort ^® daily disposable silicone hydrogel contact lenses (60 pieces) with a moisture content of 38% and the commercially available CLARITI ^® 1 DAY with a moisture content of 56% Clear silicone hydrogel daily disposable contact lenses (60 pieces) are divided into experimental group and control group. The experimental group uses the water absorption device of the contact lens of the present invention to 30 contact lenses with a water content of 38% and a water content of 38%. 56% of the 30 contact lenses were subjected to water absorption operations, and the control group was subjected to water absorption operations on 30 contact lenses with a moisture content of 38% and 30 contact lenses with a moisture content of 56% in a traditional manual manner. .

The water absorption test results of contact lenses with a moisture content of 38% and a moisture content of 56% are shown in Tables 1 and 2 below:

For the above measurement results, the Levene test is used as the homogeneity test of the variance, and whether the significant p value is less than (<)0.05 is used to determine whether there is a significant difference in the variance of the measurement results between the control group and the experimental group. The results of the Levene test As shown in Table 3 and Table 4 below:

Because the p values of the Levene test results are all less than 0.05, it means that there is a significant difference in the variation of the measurement results between the control group and the experimental group. Therefore, the coefficient of variation (Coefficient of Variation, CV) of the two groups is further compared, as shown in Table 5 below Show:

As can be seen from Table 5, two kinds of contact lenses with a water content of 38% and a water content of 56% have a coefficient of variation of the experimental group that is less than that of the control group, indicating that the water absorption device of the contact lens of the present invention is better than the traditional manual water absorption. The degree of variation of the operation method is smaller and more stable.

Please refer to FIG. 5 , which is a schematic diagram of a second embodiment of the water absorbing device of the contact lens of the present invention. The biggest difference between this embodiment and the preceding embodiments is that the water-absorbing device 100 of the contact lens also includes a buffer structure 100A, and the buffer structure 100A includes a plurality of perforations 100A1, and each perforation 100A1 is set through the buffer structure 100A, and each perforation 100A1 is used to accommodate Place a contact lens A. The cushioning structure 100A is used to be arranged on the stage 1, and the cushioning structure 100A is correspondingly located between the two water-absorbing sheets 2, and the pressing module 4 presses against the contact lens A arranged between the two water-absorbing sheets 2 At the same time, the buffer structure 100A is pressed by the pressing die set 4 at the same time. In practice, the buffer structure 100A can be made of materials such as foam, and after the buffer structure 100A is pressed by the pressing module 4 , it can recover to an unpressed state through its own elasticity.

According to the above, through the design of the buffer structure 100A, relevant personnel or mechanical arms and other equipment can better arrange the contact lenses A at a fixed position on the carrier 1, thereby improving the water absorption of the contact lenses The consistency of each operation of the device 100 can also effectively avoid problems such as overlapping of two adjacent contact lenses A.

Please refer to FIG. 6 , which is a schematic block diagram of a third embodiment of the water absorbing device for contact lenses of the present invention. The difference between this embodiment and the previous embodiments is that the processing module 5 can be connected with a verification device 200 , and the verification device 200 can read a contact lens identification unit 300 to obtain a contact lens identification data 301 . The processing module 5 may include a processor and a memory, the processor can receive the contact lens identification data 301, and the processor can find the corresponding contact lens processing information 71 in the memory according to the contact lens identification data 301, And according to the found contact lens processing information 71, the driving module 3 is controlled to operate.

Specifically, the verification device 200 can be a barcode scanner, for example, and the contact lens identification unit 300 and the user identification unit 400 are respectively a one-dimensional barcode or a two-dimensional barcode. Before 100, it is necessary to use a barcode scanner to scan the personal barcode (that is, the user identification unit 400) on its employee card, and then scan the barcode that is printed on the box of the contact lens A to be measured (that is, the invisible Glasses recognition unit 300), so that the processing module 5 can successively obtain the basic data of the user (such as employee number and other data), and the relevant data of the contact lens to be measured (such as the default moisture content of the contact lens, production batch number, etc.).

It should be noted that in the relevant laws and regulations of various countries, relevant production data of contact lenses and other related medical products must be retained for a specified period of time (generally 10 years). The design of 300 and user identification unit 400 can make it easier for manufacturers to manage related data.

In practice, in order to ensure that the relevant user data 401 and contact lens identification data 301 can be recorded every time the water absorbing device 100 of the contact lens is used, the processing module 5 can be read and used when the user uses the verification device 200 Before the user data 401 and the contact lens identification data 301, disable the activation switch of the contact lens water absorbing device 100 until the processing module 5 receives the user data 401 and the contact lens identification data 301 read by the verification device 200. Certainly, in different embodiments, the processing module 5 may also only require the user to use the verification device 200 to read the contact lens identification data 301 , without restricting the user to use the verification device 200 to read the user data 401 .

According to the above, the contact lens water absorbing device 100 of this embodiment, through the design of the verification device 200, the user identification unit 400 and the contact lens identification unit 300, can make it easier for relevant personnel to manage and control relevant data in the future, especially That is, when there is a problem with the contact lens after shipment, and the relevant personnel want to trace back all the history of the moisture content measurement of the contact lens, they can simply check the record information 201 to know.
