Abstract
Description
Technical Field
[0001] This utility model relates to the technical field, and in particular to a testing and correction device suitable for rigid endoscope tubes. Background Technology
[0002] Rigid endoscopes have wide clinical applications and clear clinical value. However, the penetration rate of endoscopes in my country still needs improvement. Domestic endoscope manufacturers have achieved rapid development in recent years, which is inextricably linked to the maturation of upstream endoscope technologies. In the early stages of development, my country's endoscope industry had a small market size and insufficient R&D motivation among upstream manufacturers; however, with the continuous growth of clinical demand, the industry's prosperity has greatly increased, and breakthroughs have been made in various upstream technological aspects of endoscopes, providing conditions for the rapid development of domestic endoscope manufacturers.
[0003] As a crucial component of rigid endoscopes (i.e., rigid endoscopes), the assembly quality of the rigid tube and the endoscope body directly affects the final product's performance. Therefore, the manufacturing quality of the rigid tube determines the subsequent assembly quality of the rigid endoscope. One of the important standards for the quality of the rigid tube is whether its own curvature parameter meets the requirements. Because the rigid tube itself has a very thin wall and a long length, this structural part with a small cross-sectional area to length ratio is very prone to bending and deformation during the manufacturing process. If this is not detected in time during the processing, it can easily lead to serious problems such as uneven fiber arrangement, optical columnar lens misalignment, or even failure to assemble properly during the assembly of the rigid tube and the endoscope body. Therefore, the curvature detection of the rigid tube is an important part of the rigid tube quality inspection.
[0004] Currently, the bending of rigid endoscope tubes is mainly detected manually, through visual observation or the use of simple measuring tools. This manual inspection method is not only inefficient but also prone to human error, affecting the accuracy of the results. Furthermore, for tubes with abnormal bending, i.e., those that do not meet quality requirements, manual straightening is usually performed, resulting in low straightening efficiency and poor straightening accuracy, ultimately leading to higher production costs.

[0040] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to exemplarily illustrate the principle of this utility model, but should not be used to limit the scope of this utility model. That is, this utility model is not limited to the described embodiments, and covers any modifications, substitutions and improvements to the parts, components and connection methods without departing from the spirit of this utility model.
[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0042] like Figure 1 As shown, this utility model relates to a detection and correction device for rigid microscope tubes, including a stage 1, a rotation and clamping assembly 2, a detection assembly 3, a linear motion assembly 4, a first clamping block 6, and a second clamping block 7. The rotation and clamping assembly 2 is mounted on the stage 1 and is used to clamp the rigid microscope tube 100 and drive it to rotate. The detection assembly 3 is mounted on the stage 1 and is used to detect the curvature of the rigid microscope tube 100. Specifically, as shown... Figure 7As shown, the curvature is the deviation between the actual distance from the laser beam F output by the laser sensor 34 on the detection component 3 to the outer surface of the rigid lens tube 100 and a preset standard distance. The preset standard distance is the detection distance from the laser beam F output by the laser sensor 34 on the detection component 3 to the outer surface of the standard rigid lens tube, which is obtained in advance. A curvature of 0 for the standard rigid lens tube means there is no deviation between the actual distance from the outer surface of the standard rigid lens tube to the laser sensor 34 and the detection distance. When the curvature is 0 or within the preset difference range, the rigid lens tube 100 is judged to be qualified. If the curvature is normal, straightening is not required. If the curvature is not zero or outside the preset difference range, the rigid lens tube is considered unqualified (abnormal) and straightening is necessary. The preset difference range can be set to ±0.1mm. That is, if the deviation between the actual distance and the preset standard distance is within ±0.1mm, the curvature is considered normal. For example, when the curvature of the rigid lens tube under test is normal, rotating it clockwise (N) for one revolution will result in the same movement trajectory at any point on the cross-section of the tube. Figure 7 S1 represents the motion trajectory of the rigid lens tube under test. At this time, the test distance from the laser beam F output by the laser sensor 34 to the outer surface of the rigid lens tube is L1, i.e., the preset standard distance. When the rigid lens tube under test has abnormal curvature, rotating it clockwise N times will cause the motion trajectory of the cross-section at the location of the abnormal curvature on the rigid lens tube to shift. Figure 7 S2 and S3 represent two positions on the cross-section of the rigid mirror tube under test, where an abnormal curvature exists. At these positions, the test distances from the laser beam F output by the laser sensor 34 to the outer surface of the rigid mirror tube are L2 and L3, respectively. L2 is the minimum detection distance from the laser beam F output by the laser sensor 34 to the cross-section at the abnormal curvature location when it reaches position S2, and L3 is the minimum detection distance from the laser beam F output by the laser sensor 34 to the cross-section at the abnormal curvature location when it reaches position S3. The maximum detection distance at position 3, where L3 is greater than L1 and L2 is less than L1, or L3-L1 and L2-L1 are both outside the range of ±0.1mm, the linear motion component 4 is mounted on the stage plate 1 and symmetrically arranged on both sides of the rotation and clamping component 2, the first clamping block 6 is mounted on one of the linear motion components 4 and the second clamping block 7 is mounted on the other linear motion component 4, wherein the first clamping block 6 and the second clamping block 7 move toward the rigid lens tube 100 under the drive of the corresponding linear motion component 4, for straightening the rigid lens tube 100 with abnormal curvature.
[0043] This invention utilizes a device that integrates detection and correction functions to detect the curvature of rigid endoscope tubes and simultaneously straighten abnormally curved rigid endoscope tubes online, thereby improving detection accuracy and straightening efficiency.
[0044] As a preferred embodiment, such as Figure 2 and Figure 3 As shown, the rotation and clamping assembly 2 includes a rotary motor 26, a turntable 21, a lens tube mounting block 22, and a first cylinder 23. The rotary motor 26 is mounted on the stage 1. Specifically, the rotary motor 26 can be arranged vertically or horizontally on the stage 1. When the rotary motor 26 is vertically arranged on the stage 1, its drive end passes through the stage 1 and connects to the turntable 21. When the rotary motor 26 is horizontally arranged on the stage 1, its drive end is connected to the turntable 21 through a transmission mechanism to convert horizontal rotational motion into vertical rotational motion. This transmission mechanism can be an existing double-gear transmission structure or a worm gear transmission structure. The rotary motor 26 is a servo motor. By controlling the rotation angle of the rotary motor 26 or pre-setting the angular velocity of the rotary motor 26, the rotational displacement of the turntable 21 can be controlled, thereby enabling the detection or straightening of the curvature at any position on the outer circumferential surface of the hard lens tube 100. For example, as shown... Figure 4 As shown, the rotary motor 26 is arranged vertically below the stage 1. The turntable 21 is mounted on the stage 1 and connected to the drive end of the rotary motor 26. Specifically, the center of the turntable 21 is collinear with the rotation center of the drive end of the rotary motor 26 to prevent the turntable 21 from making eccentric movements and reduce the difficulty of detecting the curvature of the rigid lens tube 100. For example, as shown... Figure 4As shown, the turntable 21 is arranged above the stage 1. The lens tube mounting block 22 is fixedly mounted on the turntable 21 and is used to mount the rigid lens tube 100. Specifically, the lens tube mounting block 22 is fixedly mounted on the turntable 21, that is, on the end of the lens tube mounting block 22 away from the rotary motor 26. The lens tube mounting block 22 has a groove 221 that matches the outer diameter of the rigid lens tube 100, which facilitates the placement and removal of the lens tube 100. The center of the groove 221 coincides with the center of the end of the rigid lens tube 100 that is pressed into the groove 221, further reducing the difficulty of detecting the curvature of the rigid lens tube 100. The first cylinder 23 is fixedly mounted on the turntable 21. Specifically, the first cylinder 23 is fixedly mounted on the turntable 21 and is arranged on both sides of the rigid lens tube 100 along with the lens tube mounting block 22. For example, the first cylinder 23 and the lens tube mounting block 22 are arranged along the rigid lens tube 100. The tube 100 is arranged circumferentially, and the first cylinder 23 is a telescopic cylinder. The first cylinder 23 is used to press the rigid lens tube 100 into the lens tube mounting block 22. Specifically, the telescopic end 231 of the first cylinder 23 moves towards the lens tube mounting block 22 to press the rigid lens tube 100 into the groove 221 of the lens tube mounting block 22. Thus, the first cylinder 23 and the lens tube mounting block 23 cooperate to clamp the rigid lens tube 100. It should be noted that the distance at which the telescopic end of the first cylinder 23 moves to the rigid lens tube 100 and presses it into the groove 221 of the lens tube mounting block 22 can be obtained in advance. Therefore, by setting and controlling the movement stroke of the telescopic end of the first cylinder 23 to meet the distance condition, the rigid lens tube 100 can be pressed. The above-mentioned movement stroke control of the first cylinder is existing technology, so it will not be described in detail here.
[0045] As another preferred implementation, such as Figure 2 and Figure 3 As shown, the rotation and clamping assembly 2 also includes a first photoelectric sensor 24 and a first baffle 25. The first photoelectric sensor 24 is fixedly mounted on the platform 1 and arranged circumferentially along the turntable 21. The first baffle 25 is fixedly mounted on the turntable 21. The first photoelectric sensor 24 is used to detect the position of the first baffle 25. Specifically, the first photoelectric sensor 24 is used to detect whether the first baffle 25 is in position, that is, whether the first baffle 25 is sensed when it passes the first photoelectric sensor 24, thereby determining that the first baffle 25 is in position. It can also determine whether the turntable 21 has been processed to the zero position in order to determine the starting position of the hard lens tube 100 installation, and whether the turntable 21 has completed a 360° circumferential rotation in order to determine whether the curvature detection of the hard lens tube 100 at the current position has been completed, that is, whether the curvature detection of the outer circumference of any point on the axial length of the hard lens tube 100 has been completed.
[0046] As another alternative implementation method.
[0047] Preferably, such as Figure 2 and Figure 4 As shown, the detection component 3 includes a first slide 31, a first servo motor 36, a first lead screw 35, a first slider 32, and a laser sensor 34. The first slide 31 is fixedly mounted on the stage 1. Specifically, the orientation of the first slide 31 is consistent with the mounting orientation of the rigid lens tube 100. For example, as shown... Figure 2 As shown, the first slide 31 is vertically mounted on the platform 1, and the first servo motor 36 is fixedly mounted on the first slide 31. Specifically, the first servo motor 36 can also be mounted on the platform 1 and arranged on both sides of the platform 1, with the first servo motor 36 and the first slide 31 respectively. The drive end of the first servo motor 36 passes through the platform 1 and is driven by the first lead screw 35 mounted on the first slide 31. Alternatively, the first servo motor 36 and the first slide 31 can be distributed on the same side of the platform 1, with the first servo motor 36 mounted on the end of the first slide 31 away from the platform 1. The first slide 31 is driven and connected to the first lead screw 35 mounted on the first slide 31. The movement stroke of the laser sensor 34 is controlled by setting the rotation angle of the first servo motor 36 or by pre-setting the angular velocity of the first servo motor 36, thereby enabling the detection of the curvature at any position along the axial length of the rigid mirror tube 100. The first lead screw 35 is mounted on the first slide 31 and connected to the drive end of the first servo motor 36. Specifically, the first lead screw 35 is rotatably mounted on the first slide 31, and both ends of the first lead screw 35 are smooth surfaces that are respectively connected to the first slide 31. The first slider 32, which is slidably mounted on the first slide table 31 and threaded in its middle section, is threadedly connected to the first lead screw 35. Specifically, the first slider 32 has a threaded hole to facilitate threaded connection with the threaded section of the first lead screw 35, thereby converting the rotational motion of the first lead screw 35 into the linear movement of the first slider. The laser sensor 34 is fixedly mounted on the first slider 32 and is used to detect the curvature of the rigid mirror tube 100. Specifically, the laser sensor 34 is used to detect the actual distance from the laser beam F to the outer surface of the rigid mirror tube 100. 34 can be equipped with a built-in display function or connected to a PLC controller (not shown in the figure) with a display function to display the detection results of the actual distance in real time, so as to facilitate manual recording or automatic storage. The deviation between the actual distance and the preset standard distance can be obtained by manual identification or automatic acquisition by the PLC controller. For example, if the PLC controller is used to automatically acquire the deviation between the actual distance and the preset standard distance, the preset standard distance needs to be stored in the PLC controller in advance, and the PLC controller is used to perform difference processing on the actual distance and the preset standard distance to obtain the deviation, i.e., the curvature.
[0048] Preferably, such as Figure 4As shown, the detection component 3 also includes a first limit sensor 37 and a sensor mounting bracket 33. The first limit sensor 37 is mounted on the first slide table 31 and is used to detect whether the first slider 32 has moved to the limit position on the first slide table 31. Specifically, there are two first limit sensors 37. One first limit sensor 37 is located on the slide table 31 and close to the first servo motor 36, and the other first limit sensor 37 is located on the first slide table 31 and away from the first servo motor 36. The two first limit sensors 37 can be mounted on the first slide table 31. On the same side or opposite side, the first slider 32 is provided with a second baffle (not shown in the figure). When the two first limit sensors 37 detect the second baffle respectively, it can be determined that the first slider 32 has moved to the limit position. By limiting the movement stroke of the first slider 32 on the first slide table 31, rigid collision between the first slider 32 and the first slide table 31 or the first servo motor 36 can be avoided, thereby improving the working stability and safety of the detection component. The sensor mounting bracket 33 is fixedly installed on the first slider 32 and is used to install the laser sensor 34. Specifically, the sensor mounting bracket 33 is an L-shaped mounting bracket.
[0049] Preferably, such as Figure 1 and Figure 6 As shown, each of the linear motion components 4 includes a second slide 41, a second servo motor 46, a second lead screw (not shown in the figure), a second slider 42, and a second cylinder 44. The second slide 41 is fixedly mounted on the platform 1. Specifically, the orientation of the second slide 41 is consistent with the mounting orientation of the rigid lens tube 100. For example, as shown... Figure 1As shown, the second slide 41 is vertically mounted on the platform 1. The second servo motor 46 is fixedly mounted on the second slide 41. Specifically, the assembly method of the second servo motor 46 is the same as that of the first servo motor 36, which will not be repeated here. By setting the rotation angle of the second servo motor 46, the second cylinder 44 can be moved to a position corresponding to the abnormal bending position in the axial length of the hard lens tube 100. The second lead screw is mounted on the second slide 41 and connected to the drive end of the second servo motor 46. Specifically, the structure of the second lead screw and its assembly method with the second slide 42, the second servo motor 46, and the second slider 42 are the same as those of the first lead screw 35, which will not be repeated here. The second slider 42 is slidably mounted on the second slide 41 and is threadedly connected to the second lead screw. Specifically, the structure of the second slider 42 and its assembly method with the first lead screw 35 are the same as those of the first lead screw 35, which will not be repeated here. The second slider 42 is slidably mounted on the second slide 41 and is threadedly connected to the second lead screw. The assembly method of the second lead screw is the same as that of the first slider 32, and will not be repeated here. The second cylinder 44 is mounted on the second slide table 41. Specifically, the second cylinder 44 is a telescopic cylinder, and its fixed end is mounted on the second slide table 41. The first clamping block 6 is mounted on one of the second cylinders 44, and the second clamping block 7 is mounted on the other second cylinder 44. Specifically, the telescopic ends of each of the second cylinders 44 are fixedly equipped with corresponding first clamping blocks 6 and second clamping blocks 7. The first clamping block 6 or the second clamping block 7 respectively provides auxiliary support or straightening for the rigid lens tube 100. That is, when the first clamping block 6 provides auxiliary support for the rigid lens tube 100, the second clamping block 7 straightens the rigid lens tube 100, or when the second clamping block 7 provides auxiliary support for the rigid lens tube 100, the first clamping block 6 straightens the rigid lens tube 100. Figure 8As shown, the specific straightening method includes: manipulating one of the second servo motors 46 to drive the second slider 42 to move the second cylinder 44 to the position with normal or straightened curvature closest to the position to be straightened (i.e., the position with abnormal curvature) on the axial length of the rigid lens tube 100; driving the corresponding first clamp 6 or second clamp 7 to press the rigid lens tube 100 with the telescopic end of the second cylinder 44; then manipulating another second servo motor 46 to drive the second slider 42 to move the second cylinder 44 to the position to be straightened (i.e., the position with abnormal curvature) on the axial length of the rigid lens tube 100; driving the corresponding second clamp 7 or first clamp 6 to press the rigid lens tube 100 with the telescopic end of the corresponding second cylinder 44; and completing the straightening of the rigid lens tube 100 through the cooperation of the second clamp 7 and the first clamp 6. It should be noted that the distance at which the telescopic end of the second cylinder 44 drives the corresponding first clamping block 6 or second clamping block 7 to move to the area on the standard rigid lens tube or the rigid lens tube 100 under test without bending abnormalities and to fit against the outer surface of the standard rigid lens tube or the rigid lens tube 100 under test can be obtained in advance. Therefore, by setting and controlling the movement stroke of the telescopic end of the second cylinder 44 to meet the distance condition, the first clamping block 6 or the second clamping block 7 can support and straighten the rigid lens tube 100 respectively. The movement stroke control of the second cylinder is existing technology, so it will not be described in detail here.
[0050] Preferably, such as Figure 6 As shown, the linear motion assembly 4 also includes a second limit sensor 47 and a mounting bracket 43. The second limit sensor 47 is mounted on the second slide table 41 and is used to detect whether the second slider 42 has moved to the limit position on the second slide table 41. Specifically, there are two second limit sensors 47. One second limit sensor 47 is located on the second slide table 41 and close to the second servo motor 46, and the other second limit sensor 47 is located on the second slide table 41 and away from the second servo motor 46. The two second limit sensors 47 can be mounted on the same side of the second slide table 41 or... On the opposite side, the second slider 42 is provided with a third baffle 45. When the second limit sensor 47 detects the third baffle 45, it can be determined that the second slider 42 has moved to the limit position. By limiting the movement stroke of the second slider 42 on the second slide table 41, rigid collisions between the second slider 42 and the second slide table 41 or the second servo motor 46 can be avoided, thereby improving the working stability and safety of the detection component. The mounting bracket 43 is fixedly installed on the second slider 42 and is used to install the second cylinder 44. Specifically, the mounting bracket 43 is an L-shaped mounting bracket used to install the fixed end of the second cylinder 44.
[0051] Preferably, such as Figure 1 and Figure 5As shown, the detection and correction device also includes an auxiliary limiting component 5, which is fixedly connected to the end of each linear motion component 4 away from the stage plate 1. Specifically, because the rigid lens tube 100 is relatively long and has a thin wall, the middle part of the rigid lens tube 100 is more prone to bending deformation during the production process than the two ends. Furthermore, the rigid lens tube exhibits various bending types, such as unidirectional deviation, bidirectional deviation, and spiral deviation, or combinations of two or more of these. Unidirectional deviation indicates that the bending direction of the rigid lens tube deviates in a single direction, while bidirectional deviation indicates that the bending direction of the rigid lens tube deviates in two directions, typically manifesting as bilateral deviation or spiral deviation. The deviation type is characterized by the bending direction of the rigid lens tube shifting in multiple directions, usually manifested as a spiral bending structure. Therefore, in order to facilitate the straightening of rigid lens tubes with abnormal curvature, especially when straightening rigid lens tubes with spiral bending structures, it is necessary to limit the end of the rigid lens tube 100 away from the tube mounting block 22 that is pressed against the rotating and clamping assembly 2. This can prevent the rigid lens tube 100 from deflecting in the radial direction of the rigid lens tube during the straightening process, thereby further improving the straightening efficiency and straightening accuracy. Specifically, the auxiliary limiting assembly 5 is set above the stage plate 1 and is fixedly connected to the ends of the two linear motion assemblies 4 and the detection assembly 3 away from the stage plate 1.
[0052] Preferably, such as Figure 5As shown, the auxiliary limiting component 5 includes a connecting plate 51, a cylinder support frame 52, a third cylinder 53, and a limiting plate 54. The connecting plate 51 is fixedly connected to the end of the second slide 41 of each linear motion component 4 away from the platform 1. Specifically, the connecting plate is a T-shaped connecting plate. The second slide 41 of the two linear motion components 4 and the first slide 31 of the detection component 3 are all fixedly connected to the connecting plate 51, thereby ensuring the motion stability of the linear motion components 4 and the detection component 3. The cylinder support frame 52 is fixedly installed in the middle of the connecting plate 51. Specifically, the cylinder support frame 52 is installed in the middle of the connecting plate 51 and located at the center of the connecting plate 51. Below 1, that is, between the connecting plate 51 and the platform 1, the third cylinder 53 is fixedly mounted on the cylinder support frame 52. Specifically, the third cylinder 53 is a telescopic cylinder, and its fixed end is fixedly mounted on the cylinder support frame 52. The limiting plate 54 is fixedly mounted on the telescopic end of the third cylinder 53 to limit the radial swing of the end of the rigid lens tube 100 away from the rotation and clamping assembly 2 within the limiting plate 54. Specifically, the limiting plate 54 is provided with a slot 541 that matches the end face of the rigid lens tube 100. The telescopic end of the third cylinder 53 drives the limiting plate 54 to move and limit one end of the rigid lens tube 100 within the slot 541. It should be noted that the distance at which the extension end of the third cylinder 53 drives the limiting plate 54 to move to the end of the rigid lens tube 100 away from the stage plate 1 and limits it within the slot 541 of the limiting plate 54 can be obtained in advance. Therefore, by setting and controlling the movement stroke of the extension end of the third cylinder 53 to meet the distance condition, the end of the rigid lens tube 100 away from the stage plate 1 can be limited. The movement stroke control of the third cylinder is existing technology, so it will not be described in detail here.
[0053] Preferably, such as Figures 1 to 6As shown, the detection and correction equipment also includes a PLC controller (not shown in the figure). The PLC controller is electrically connected to the detection component 3, the rotation and clamping component 2, and each linear motion component 4. Specifically, the PLC controller is electrically connected to the first servo motor 36, laser sensor 34, and first limit sensor 37 of the detection component 3; the rotation motor 26, first cylinder 23, and first photoelectric sensor 24 of the rotation and clamping component 2; the second servo motor 46, second limit sensor 47, and second cylinder 44 of the linear motion component 4; and the third cylinder 53 of the auxiliary pressing component 5. For example, the PLC controller is a Siemens S7-200 PLC. CPU226 first controls the first cylinder 23 via PLC controller to press the rigid mirror tube 100 to meet the requirements for detection and straightening. Then, by controlling the rotation angle or angular velocity of the rotary motor 26 and the first servo motor 36, it can automatically detect the curvature of the rigid mirror tube at any position along its axial and circumferential length. By receiving position signals or arrival signals from the first limit sensor 37, the first photoelectric sensor 24, and the second limit sensor 47, it controls the corresponding first slider 32, turntable 21, and second slider 33 to stop moving, thereby ensuring the stability and safety of the detection and straightening equipment and the accuracy of the curvature parameter detection. Then, by controlling the extension and retraction of the third cylinder 53, it presses the rigid mirror tube 100 to further meet the requirements for straightening operation. Finally, by controlling the rotation angle or angular velocity of the rotary motor 26, the second servo motor 46, and the extension and retraction of the second cylinder 44, it automatically straightens the positions with abnormal curvature, thus realizing the automated operation of detection and straightening of the rigid mirror tube.
