[0030] This application also discloses a method for using an ophthalmic scalpel performance testing instrument, which employs the aforementioned ophthalmic scalpel performance testing instrument, including: Step 1: The conveyor belt mechanism 2 and the vision mechanism 4 are used to perform a preliminary inspection of the scalpel to be inspected, and the shape data is transmitted to the control system.

[0031] In the preceding production stage, the equipment places the handle of the scalpel to be inspected on the upper end of the support 3, so that the blade of the scalpel faces the vision mechanism 4. The conveyor belt mechanism 2 drives the support 3 to move, thereby moving the scalpel. During the movement, the vision mechanism 4 captures the shape data of the scalpel blade and transmits the obtained shape data to the control system. The control system compares the actual shape data obtained by the vision mechanism 4 with the design value of the blade. When the actual shape data exceeds the allowable error range, the scalpel is judged to be unqualified. The initial inspection of the scalpel is completed by the vision mechanism 4.

[0032] The control system transmits the detection results of the scalpels to the robotic arm 5. The robotic arm 5, which is close to the vision mechanism 4, randomly samples the qualified scalpels. The unsampled scalpels continue to move to the waste box 19 under the action of the conveyor belt mechanism 2. During this process, another set of robotic arms 5 grabs the qualified scalpels and places them into the finished product box 20 to realize the storage of qualified products. The unqualified scalpels fall directly into the waste box 19 with the conveyor belt mechanism 2 for easy recycling.

[0033] Step 2: The robotic arm 5 samples the qualified scalpels and uses the limiting mechanism 8 to limit their movement.

[0034] The robotic arm 5, which samples scalpels, grabs the sample that has passed the initial inspection and inserts the handle of the sample scalpel horizontally into the groove 83 of the limiting mechanism 8, so that the blade is located outside the housing 81.

[0035] When the second push rod 88 is activated, it extends into the groove 83, causing the flexible block 89 to press against the handle of the scalpel. The anti-slip strip 84 and the flexible block 89 work together to prevent the handle from rotating, thus limiting the position of the handle and adapting to multiple sets of handles of different specifications.

[0036] The control motor drives the turntable 6 to rotate, and the turntable 6 drives each set of limit mechanisms 8 to rotate, thereby causing the limit mechanisms 8 to move the sample scalpel to the detection station of the detection mechanism 10.

[0037] Step 3: After the scalpel moves to the testing station, the slide mechanism 9 is activated. The slide mechanism 9 adjusts the position of the testing mechanism 10 and activates the push rod 18. The push rod 18 pushes the pressure block 16 and the shear blade 17 to achieve the strength test of the blade.

[0038] Method 1: Test the compressive strength of the blade.

[0039] The slide mechanism 9 adjusts the position of the detection mechanism 10, and the motor 12 is started, causing the pressure block 16 to move above the blade and the pressure pad 15 to move below the blade, so that the blade is placed above the pressure pad 15 (e.g., Figure 9 (As shown).

[0040] Since the fixing block 14 is fixedly installed and the slide groove 142 and the slider 152 are slidably connected, the slider 152 moves downward under the action of gravity. When the slider 152 slides to the bottom of the slide groove 142, the fixing block 14 provides support for the pressure pad 15.

[0041] The push rod 18 connected to the pressure block 16 is activated. The push rod 18 pushes the pressure block 16 to move towards the pressure pad 15, causing the pressure block 16 to squeeze the blade. The control system calculates the pressure applied by the push rod 18 by the magnitude of the current of the push rod 18. The calculation principle is existing technology.

[0042] When the camera 91 observes the deformation of the blade, the control system records the pressure at this time, which is the pressure resistance limit of the blade. The push rod 18 drives the pressure block 16 away from the blade, and the motor 12 drives the limit mechanism 8 away from the detection mechanism 10, so that the detection mechanism 10 can detect the remaining sample blades.

[0043] It should be noted that blades are precision structures, and strength testing is a destructive test, which inevitably causes damage to the blade itself. Therefore, different blades need to be used for different testing methods. Even if the blade passes the test, the qualified scalpel should still be scrapped.

[0044] Method 2: Test the shear strength of the blade.

[0045] Start motor 12 and slide mechanism 9 to move shear blade 17 and shear blade 141 to the upper and lower sides of the blade respectively. Under the action of gravity, slider 152 moves along slide groove 142 towards the pressure block 16, causing pressure pad 15 to move towards the pressure block 16. At this time, shear blade 141 is fully exposed (e.g., Figure 10 (As shown).

[0046] Make the blade contact the first shear blade 141, activate the third push rod 18 connected to the second shear blade 17, the third push rod 18 pushes the second shear blade 17, so that the second shear blade 17 and the first shear blade 141 apply shearing force to the blade from both sides until the camera 91 observes the blade breakage, and the control system records the maximum shearing force at this time, which is the shear strength of the blade.

[0047] Method 3: Perform unilateral shear resistance testing on the blade.

[0048] Start motor 12 and slide mechanism 9 to move shear blade 17 and shear blade 141 to the upper and lower sides of the blade respectively, causing pressure pad 15 to move closer to pressure block 16. The principle is the same as in method two. At this time, start push rod 18 connected to pressure block 16. Push rod 18 pushes pressure block 16 towards pressure pad 15, thereby pushing pressure pad 15 towards shear blade 17 until pressure pad 15 covers shear blade 141 (e.g., ...). Figure 11As shown), at this time, the pressure pad 15 is located below the second shear blade 17. The control motor 2 12 and the slide mechanism 9 are adjusted to place the blade above the pressure pad 15 to provide support for the blade. The push rod 3 18 connected to the second shear blade 17 is activated to make the second shear blade 17 cut the blade. When the camera 91 observes that the blade breaks, the control system records the maximum shearing force at this time to obtain the shear strength of the blade.

[0049] It should be noted that when the scalpel is grasped by the robotic arm 5 and enters the limiting mechanism 8, the tilt angle of the blade is random. Therefore, in the strength test, the guide tube 13 is rotated by the second motor 12 to adjust the detection angle of the detection mechanism 10 to adapt to more situations. Since in Method 1, the pressure pad 15 is supported by the fixed block 14 under the action of gravity, in the pressure test, the pressure pad 15 is positioned below the central axis of the scalpel by the second motor 12. At this time, it can be ensured that the fixed block 14 provides support for the pressure pad 15.

[0050] Method 4: Group testing based on the actual thickness of the scalpel.

[0051] The vision mechanism 4 obtains the shape data of the blade during the initial inspection. The control system groups the blades according to their actual thickness. In the prior art, the thickness of the blade has an allowable deviation range. The deviation range is divided into three levels: small deviation, medium deviation, and extreme deviation.

[0052] Scenario 1: If the actual thickness deviation of the blade does not exceed one-third of the allowable deviation, it is classified as a small deviation. Blades with small deviations are tested according to methods one to three. If all test items are qualified, it means that the blade thickness is qualified under small fluctuation range. The test results are fed back to vision mechanism 4. Blades that meet the thickness range in the initial inspection are judged as qualified.

[0053] If any test fails, it indicates that the reason for the failure to meet the strength standard is a defect in the processing of the blade material, and the production process should be investigated.

[0054] Scenario 2: If the actual thickness deviation of the blade is between one-third and two-thirds of the allowable deviation, it is classified as a medium deviation, and the same test method 1 to method 3 is performed on this group of blades.

[0055] If the blade is thick enough and passes the inspection, it means that the blade still meets the strength requirements even when it is moderately thick, and the blade's manufacturing process is within acceptable limits.

[0056] If the blade is too thick and substandard, it indicates that the increased thickness has led to stress concentration or uneven structure inside the blade, requiring grinding.

[0057] If the blade is thin enough to meet the acceptable standard, it means that there is still a safety margin in the blade, and the production process can be optimized to further reduce costs.

[0058] If the cutting blade is too thin and substandard, it indicates that the blade's strength is insufficient due to its thinness, and the machining accuracy should be improved.

[0059] Scenario 3: If the actual thickness deviation of the blade is between two-thirds of the allowable deviation and the maximum value, it is classified as a limit deviation, and the blades in this group are tested using methods one to three.

[0060] If the test is passed, it means that the blade has a sufficiently large safety margin, and the current blade processing and material solutions can be considered as the preferred options.

[0061] If the test fails, the upper limit of the thickness of the thicker blades should be limited and the lower limit of the thickness of the thinner blades should be increased in the production process.

[0062] Furthermore, in methods one through three, the blade is crushed or sheared and breaks, with the broken blade falling directly into the waste box 21 for easy operator recycling.

[0063] Motor 1 drives turntable 6 to rotate, turntable 6 drives limit mechanism 8 to rotate, limit mechanism 8 drives the scalpel that has completed the test to move into the waste box 22. When the limit mechanism 8 drives the scalpel to move above the waste box 22, control push rod 2 88 drives flexible block 89 away from the scalpel handle, releases the limit, and starts push rod 1 87. Push rod 1 87 pushes lever 86, causing lever 86 to push the scalpel handle away from the box 81, pushing the scalpel out of the limit mechanism 8 and into the waste box 22 for easy recycling.

[0064] Furthermore, the detection results from Method 4 are fed back to the vision mechanism 4 to improve the detection standards of the vision mechanism 4. For example, in Method 4, blades with small and medium deviations are all qualified, but blades with extreme deviations are unqualified. The control system feeds back the results to the vision mechanism 4, which can determine the scalpels with extreme deviations as unqualified during the initial inspection. This allows the robotic arm 5 to sample and store scalpels with small and medium deviations, further improving work efficiency.
