Description

Technical Field

[0001] The present application relates to the technical field of endoscope performance testing, and in particular to an optical endoscope rod performance testing system and testing method. Background Art

[0002] The optical endoscope includes a mirror rod and a camera. The mirror rod is the core part of the optical endoscope, which is equipped with an objective lens, a cylindrical lens group and an eyepiece. The mirror rod is used to insert into the target area and is responsible for collecting images. The end of the mirror rod close to the eyepiece is connected to the camera, which converts the image collected by the mirror rod into an electronic signal and transmits it to an external display device through a data cable.

[0003] As a conventional minimally invasive surgical instrument, the imaging performance of the mirror shaft of the optical endoscope directly affects the doctor's surgical efficiency and quality. Therefore, the imaging performance of the mirror shaft needs to be strictly tested before leaving the factory. When testing the imaging performance of the mirror shaft, it is necessary to prepare different test cards (for example: resolution test card, color reproduction test card, gradient test card, checkerboard test card, field of view test card, uniform illumination test card), and select the corresponding test card to be installed on the test device for testing when performing different test items. For example, when testing the resolution of the mirror shaft, the resolution test card is selected for testing; when testing the color reproduction of the mirror shaft, the color reproduction test card is selected. In traditional technology, it is usually necessary to rely on test personnel to manually replace the test card, which leads to low testing efficiency. Summary of the invention

[0004] Based on this, it is necessary to provide an optical endoscope rod performance testing system and testing method to address the above problems.

[0005] In order to solve the above problems, the present application provides the following technical solutions:

[0006] An optical endoscope rod performance testing system, the optical endoscope rod performance testing system comprising:

[0007] A camera, a mirror pole fixing frame and a changer, wherein the camera, the mirror pole fixing frame and the changer are arranged in sequence along the direction of the camera lens, the changer has six degrees of freedom, and the side of the changer facing the camera when testing the endoscope is the side directly opposite to the changer;

[0008] A first connector is fixedly mounted on the opposite side of the changer; and

[0009] An alternative unit comprises a storage station, a plurality of different test cards and a plurality of first mounting seats, each of the first mounting seats having a first opposite side and a first mounting area; the first mounting seats and the test cards are arranged in a one-to-one correspondence, each of the test cards is fixedly arranged in the first mounting area of ​​the corresponding first mounting seat and is visible from the outside of the first opposite side of the corresponding first mounting seat; the storage station and the changer are arranged side by side, each of the first mounting seats can be detachably arranged in the storage station and is at least partially visible from the outside of the storage station, so that each of the first mounting seats can be detachably fixedly connected to the first connector.

[0010] The optical endoscope rod performance testing system has at least the following beneficial effects:

[0011] In the process of using the optical endoscope mirror rod performance test system, the first joint can be made to reach any first mounting seat by using a changer with six degrees of freedom. After reaching one of the first mounting seats, the changer is moved to fix the first joint with the first mounting seat, and the first mounting seat is moved away from the storage station. The changer is then moved until the test card in the first mounting seat appears in the field of view of the camera, and then the imaging quality of the mirror rod can be tested using the test card. After the imaging quality of the mirror rod is completed using the test card, the changer is moved until the first mounting seat fixed on the first joint returns to its position on the storage station, and the first joint is separated from the first mounting seat. Repeating the above process, the test card can be replaced for testing. Because these processes are automatically completed by the changer, there is no need to rely on the tester to manually replace the test card, thereby improving the test efficiency.

[0012] In one embodiment, each of the first mounting seats includes a first seat body, a second joint and a first elastic member, the first opposite side is a side of the first seat body, the first mounting area is arranged on the first seat body, the first seat body also has a first back-to-back side opposite to the first opposite side, the first seat body is provided with a first channel extending from the first back-to-back side toward the first opposite side, and the first channel is visible from the outside of the storage station; the second joint can be slidably passed through the side wall of the first channel to enter and exit the first channel, and the first elastic member is clamped between the second joint and the first seat body along the sliding direction of the second joint; the first joint can enter and exit the first channel and a groove adapted to the second joint is provided on the outer periphery of the first joint; a plurality of first unlocking members are fixed on the storage station, and the first unlocking members and the second joints are arranged one by one; each of the first unlocking members abuts against a side of the corresponding second joint away from the first elastic member to push the second joint out of the first channel.

[0013] With such a configuration, when in use, the movable changer allows the first joint to extend into a first channel on a first mounting seat, and allows the groove on the first joint to face the second joint. Then, the changer is moved in a direction away from the first unlocking member to allow the second joint to disengage from the first unlocking member. The first elastic member pushes the second joint portion to slide into the first channel and extend into the groove on the first joint during the process of the second joint disengaging from the first unlocking member. In this way, the first joint is fixedly connected to the first mounting seat, and the changer can move with the first mounting seat. Conversely, the movable changer moves the changer toward the first unlocking member until the second joint abuts against the first unlocking member, so that the second joint can withdraw from the groove on the first joint. The first elastic member is gradually compressed during the process of the second joint withdrawing from the groove. Then, the movable changer allows the first joint to move along the first channel, so that the first joint can withdraw from the first channel, thereby completing the separation of the first joint from the first mounting seat.

[0014] In one embodiment, a slide groove is provided on the first seat body, the second joint portion is located in the slide groove on the first seat body, and the first unlocking member forms a slide rail adapted to the slide groove on the first seat body and is slidably connected to the slide groove on the first seat body.

[0015] With this arrangement, the first seat body forms a sliding connection with the first unlocking member through the sliding groove, so that the first seat body can slide relative to the first unlocking member to control the second joint to enter and exit the first channel, and can ensure that the first unlocking member and the second joint are stably abutted.

[0016] In one embodiment, each of the first unlocking members is arranged along the vertical direction, each of the first mounting seats is overlapped on the top side of the first unlocking member through the second joint, and all of the test cards are perpendicular to the direction of the camera lens.

[0017] In this arrangement, because the test card is perpendicular to the direction of the camera lens, after the first mounting seat is removed from the storage station, there is no need to adjust the posture of the changer, and only the changer needs to be translated to make the test card in the first mounting seat appear in the camera's field of view, and the test card is facing the camera. This reduces the number of times the posture of the changer needs to be adjusted, and can improve test efficiency.

[0018] In one embodiment, the alternative unit also includes a backlight source and a second mounting seat, the second mounting seat having a second opposite side and a second mounting area; the backlight source is fixedly arranged in the second mounting area and is visible from the outside of the second opposite side; the second mounting seat can be detachably arranged in the storage station and is at least partially visible from the outside of the storage station, so that the second mounting seat can be detachably fixedly connected to the first connector; a first electrical connector is fixedly arranged on the opposite side of the changer, a second electrical connector corresponding to the first electrical connector is arranged on the second mounting seat, and the backlight source is electrically connected to the second electrical connector; a third connector is fixedly arranged on the second opposite side, the third connector is the same as the first connector, and when the second mounting seat is fixedly connected to the first connector, the groove on the third connector is oriented in the same direction as the groove on the first connector; each of the test cards is visible from the outside of the first opposite side of the corresponding first mounting seat.

[0019] With such arrangement, when in use, the first connector can be made to reach the second mounting seat by using the changer, and then the first connector is fixedly connected to the second mounting seat, and the second mounting seat is made to leave the storage station. Then, the movable changer makes the third connector reach one of the first mounting seats, and the third connector is fixedly connected to the first mounting seat. At this time, the second directly opposite side is opposite to the first back-to-back side, and the light emitted by the backlight source shines on the test card installed on the first mounting seat. In this way, the backlight source is added to the back of the test card. The process of disassembling the test card and the backlight source from the changer is as follows: the movable changer is moved until the first mounting seat fixed on the third connector returns to its position on the storage station, and the third connector is separated from the first mounting seat. Then, the movable changer is moved until the second mounting seat fixed on the first connector returns to its position on the storage station, and the first connector is separated from the second mounting seat. In short, the operation of adding a backlight source to the back of the test card can be completed by the movable changer, which does not rely on manual labor and can improve the test efficiency.

[0020] In one embodiment, the second mounting base includes a second base body, a fourth connector and a second elastic member, the second opposite side is a side of the second base body, the second mounting area and the second electrical connector are both arranged on the second base body, the second base body also has a second back-to-back side opposite to the second opposite side, the second base body is provided with a second channel extending from the second back-to-back side toward the second opposite side, the second channel is the same as the first channel and is visible from the outside of the storage station; the fourth connector is the same as the second connector, and the fourth connector can be slidably passed through the side wall of the second channel to enter and exit the second channel, and the second elastic member is clamped between the fourth connector and the second base body along the sliding direction of the fourth connector; a second unlocking member is fixedly provided on the storage station, and the second unlocking member abuts against a side of the fourth connector away from the second elastic member to push the fourth connector out of the second channel.

[0021] With such a configuration, when in use, the movable changer allows the first joint to extend into the second channel on the second mounting seat, and allows the groove on the first joint to face the fourth joint. Then, the changer is moved in a direction away from the second unlocking member to allow the fourth joint to disengage from the second unlocking member. The second elastic member pushes the fourth joint part to slide into the second channel and extend into the groove on the first joint during the process of the fourth joint disengaging from the second unlocking member. In this way, the first joint is fixedly connected to the second mounting seat, and the changer can move with the second mounting seat. Conversely, the movable changer moves the changer toward the second unlocking member until the fourth joint abuts against the second unlocking member, so that the fourth joint can withdraw from the groove on the first joint. The second elastic member is gradually compressed during the process of the fourth joint withdrawing from the groove. Then, the movable changer allows the first joint to move along the second channel, so that the first joint can withdraw from the second channel, thereby completing the separation of the first joint from the second mounting seat.

[0022] In one embodiment, the alternative unit also includes an illuminance meter and a third mounting seat, the third mounting seat having a third opposite side and a third mounting area; the illuminance meter is fixedly mounted in the third mounting area and is visible from the outside of the third opposite side; the third mounting seat can be detachably arranged in the storage station and is at least partially visible from the outside of the storage station, so that the third mounting seat can be detachably fixedly connected to the first connector; a first electrical connector is fixedly provided on the opposite side of the changer, a second electrical connector corresponding to the first electrical connector is provided on the third mounting seat, and the illuminance meter is electrically connected to the second electrical connector.

[0023] With such a configuration, when in use, the first joint can be moved to the third mounting seat by using the changer, and then the first joint can be fixedly connected to the third mounting seat, and then the changer can be moved to the test area, and then the illumination meter in the third mounting seat can be used to test the lighting effectiveness of the mirror rod. After the lighting effectiveness test is completed, the changer can be moved until the third mounting seat fixed on the first joint returns to its position on the storage station, and the first joint is separated from the third mounting seat.

[0024] The present application also provides a method for testing the performance of an optical endoscope rod, which is applied to the above-mentioned optical endoscope rod performance testing system, and the method comprises the following steps:

[0025] a. Install the mirror rod to be tested to the mirror rod fixing frame;

[0026] b. Move the changer to allow the first joint to extend into a first channel on a first mounting seat that holds a test card to be tested separately, and allow the groove on the first joint to face the second joint; move the changer in a direction away from the first unlocking member to allow the second joint to disengage from the first unlocking member, wherein the first elastic member pushes the second joint portion to slide into the first channel and extend into the groove on the first joint during the process of the changer disengaging from the first unlocking member; then, move the changer until the test card on the first mounting seat appears in the field of view of the camera to test the imaging quality of the mirror rod;

[0027] c. After testing the imaging quality of the mirror rod in step b, move the changer to the second joint to abut against the first unlocking piece, and continue to move the changer toward the first unlocking piece to make the second joint withdraw from the groove on the first joint, and then move the changer to make the first joint withdraw from the first channel to complete the separation of the first joint and the first mounting seat.

[0028] The optical endoscope rod performance testing method has at least the following beneficial effects:

[0029] By performing step b and step c once, the imaging quality of the scope shaft can be tested with one test card. By repeating step b and step c, the test card can be changed for testing. In the optical endoscope scope shaft performance testing method, step b and step c are automatically completed by the changer, and there is no need to rely on the tester to manually change the test card, thereby improving the testing efficiency.

[0030] In one embodiment, step b comprises the following steps:

[0031] b1, move the changer until the first joint is aligned with the first channel and the groove on the first joint faces upward, then move the changer in the horizontal direction until the first joint extends into the first channel and the groove on the first joint faces the second joint; then move the changer in the vertical upward direction until the first mounting seat is separated from the first unlocking member; then translate the changer until the test card on the first mounting seat appears in the field of view of the camera;

[0032] Step c comprises the following steps:

[0033] c1. After testing the imaging quality of the mirror rod, move the changer until the second joint is located directly above the first unlocking piece and the slide groove on the first seat body is aligned with the first unlocking piece. Then, move the changer in a vertical downward direction to make the slide groove on the first mounting seat cover the outside of the first unlocking piece and make the second joint exit the groove on the first joint. Then, move the changer horizontally to make the first joint exit the first channel.

[0034] With such arrangement, in step b1, after the slide groove on the first mounting seat is separated from the first unlocking member, the test card on the first mounting seat can be made to appear in the camera's field of view by only translating the changer, which reduces the number of times the changer posture is adjusted and can improve test efficiency.

[0036] d. moving the changer to allow the first joint to extend into the second channel on the second mounting seat, and allowing the groove on the first joint to face the fourth joint; moving the changer in a direction away from the second unlocking member to allow the fourth joint to disengage from the second unlocking member, wherein the second elastic member pushes the fourth joint portion to slide into the second channel and extend into the groove on the first joint during the process of the changer disengaging from the second unlocking member;

[0037] e. Move the changer so that the third joint on the second mounting seat extends into the first channel on the first mounting seat which is provided with a test card to be tested together with the backlight source, and the groove on the third joint is directly opposite to the second joint; move the changer in a direction away from the first unlocking member to disengage the second joint from the first unlocking member, wherein the first elastic member pushes the second joint part to slide into the first channel and extend into the groove on the first joint during the process of the changer disengaging from the first unlocking member; then, move the changer until the test card on the first mounting seat appears in the field of view of the camera to test the imaging quality of the mirror rod;

[0038] f. After testing the imaging quality of the mirror rod in step e, the movable changer is moved until the second joint abuts against the first unlocking member, and the changer is further moved toward the first unlocking member to make the second joint exit the groove on the third joint, and then the third joint is exited from the first channel by moving the changer, thereby completing the separation of the third joint and the first mounting seat;

[0039] g. Move the changer until the fourth joint abuts against the second unlocking piece, continue to move the changer toward the second unlocking piece to make the fourth joint withdraw from the groove on the first joint, and then move the changer to make the first joint withdraw from the second channel to complete the separation of the first joint and the second mounting seat.

[0040] With such a configuration, the operation of adding a backlight source to the back of the test card can be completed through step d and step e, and the operation of removing the test card and the backlight source from the changer can be completed through step f and step g. These operations do not rely on manual labor, which can improve the test efficiency. Repeating step e and step f can replace the test card for testing, so that different test cards and backlight sources can be used to test the imaging quality of the mirror pole. This process also does not require the tester to manually replace the test card, which can improve the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] See also Figure 1 and Figure 2 The present application provides a system for testing the performance of an optical endoscope mirror rod, which includes a camera 1, a mirror rod fixing frame 2, and a changer 3. The camera 1, the mirror rod fixing frame 2, and the changer 3 are arranged in sequence along the direction of the lens of the camera 1. The changer 3 has six degrees of freedom. The side of the changer 3 facing the camera 1 when testing the endoscope is the opposite side 31 of the changer. During the test, the mirror rod 7 to be tested is fixed on the mirror rod fixing frame 2, so that the lens of the camera 1 and the mirror rod 7 are coaxial. After different test cards 6 are fixed on the opposite side 31 of the changer in batches, the changer 3 is moved to change the position and posture of the test card 6, and the image of the test card 6 transmitted by the mirror rod 7 is captured by the camera 1, so as to test the imaging quality of the mirror rod 7.

[0058] See also Figures 3 to 8The optical endoscope rod performance test system also includes a first joint 4 and an alternative unit 5. The first joint 4 is fixedly arranged on the opposite side 31 of the changer. The alternative unit 5 includes a storage station 51, a plurality of different test cards 6 and a plurality of first mounting seats 52. Each first mounting seat 52 has a first opposite side 5211 and a first mounting area 5213. The first mounting seats 52 and the test cards 6 are arranged in a one-to-one correspondence, and each test card 6 is fixedly arranged in the first mounting area 5213 of the corresponding first mounting seat 52 and is visible from the outside of the first opposite side 5211 of the corresponding first mounting seat 52. The storage station 51 is arranged side by side with the changer 3, and each first mounting seat 52 can be detachably arranged in the storage station 51, and each first mounting seat 52 is at least partially visible from the outside of the storage station 51, so that each first mounting seat 52 can be detachably fixedly connected to the first joint 4.

[0059] In the process of using the optical endoscope mirror rod performance test system, the first joint 4 can be made to reach any first mounting seat 52 by using the changer 3 with six degrees of freedom. After reaching one of the first mounting seats 52, the changer 3 is moved to fix the first joint 4 with the first mounting seat 52, and the first mounting seat 52 is moved away from the storage station 51, and the changer 3 is moved again until the test card 6 in the first mounting seat 52 appears in the field of view of the camera 1, and then the imaging quality of the mirror rod 7 can be tested by using the test card 6. After the imaging quality of the mirror rod 7 is completed by using the test card 6, the changer 3 is moved until the first mounting seat 52 fixed on the first joint 4 returns to its position on the storage station 51, and the first joint 4 is separated from the first mounting seat 52. Repeating the above process, the test card 6 can be replaced for testing. Because these processes are automatically completed by the changer 3, there is no need to rely on the tester to manually replace the test card 6, thereby improving the test efficiency.

[0060] Exemplarily, the optical endoscope rod performance test system further comprises a base, and the changer 3 is mounted on the base and can move with six degrees of freedom relative to the base. The base and the storage station 51 are fixedly connected or respectively fixed to the ground.

[0061] Exemplarily, the dress changer 3 is the end effector of a six-degree-of-freedom robotic arm, or the dress changer 3 is the end effector of a flexible robotic arm.

[0062] See also Figures 5 to 8Each first mounting seat 52 includes a first seat body 521, a second joint 522 and a first elastic member 523. The first opposite side 5211 is a side of the first seat body 521, the first mounting area 5213 is provided on the first seat body 521, the first seat body 521 also has a first opposite side 5212 opposite to the first opposite side 5211, the first seat body 521 is provided with a first channel 5214 extending from the first opposite side 5212 toward the first opposite side 5211, and the first channel 5214 is visible from the outside of the storage station 51. The second joint 522 is slidably provided through the side wall of the first channel 5214 to enter and exit the first channel 5214, the first elastic member 523 is clamped between the second joint 522 and the first seat body 521 along the sliding direction of the second joint 522, and the first elastic member 523 is used to push the second joint 522 to partially slide into the first channel 5214. The first connector 4 can enter and exit the first passage 5214, and a groove 41 adapted to the second connector 522 is provided on the outer periphery of the first connector 4. A plurality of first unlocking members 511 are fixedly provided on the storage station 51, and the first unlocking members 511 and the second connector 522 are arranged one by one. Each first unlocking member 511 abuts against a side of the corresponding second connector 522 away from the first elastic member 523 to push the second connector 522 out of the first passage 5214. When in use, the movable changer 3 allows the first connector 4 to extend into the first passage 5214 on a first mounting seat 52, and allows the groove 41 on the first connector 4 to face the second connector 522. Then, the changer 3 is moved in a direction away from the first unlocking member 511 to make the second joint 522 disengage from the first unlocking member 511. The first elastic member 523 pushes the second joint 522 to partially slide into the first channel 5214 and extend into the groove 41 on the first joint 4 during the process of the second joint 522 disengaging from the first unlocking member 511. In this way, the first joint 4 is fixedly connected to the first mounting seat 52, and the changer 3 can move with the first mounting seat 52. On the contrary, the movable changer 3 moves toward the first unlocking member 511 until the second joint 522 abuts against the first unlocking member 511, so that the second joint 522 can withdraw from the groove 41 on the first joint 4. The first elastic member 523 is gradually compressed during the process of the second joint 522 withdrawing from the groove 41. Then, the movable changer 3 moves the first joint 4 along the first channel 5214, so that the first joint 4 can withdraw from the first channel 5214, thereby completing the separation of the first joint 4 from the first mounting seat 52.

[0063] Exemplarily, the first elastic member 523 is a spring or a rubber member.

[0064] See also Figure 6 and Figure 7The first seat body 521 is provided with a slide groove 5215, and the second joint 522 is partially located in the slide groove 5215 on the first seat body 521. The first unlocking member 511 forms a slide rail adapted to the slide groove 5215 on the first seat body 521 and is slidably connected to the slide groove 5215 on the first seat body 521. In this way, the first seat body 521 forms a sliding connection with the first unlocking member 511 through the slide groove 5215, so that the first seat body 521 slides relative to the first unlocking member 511 to control the second joint 522 to enter and exit the first channel 5214, and can ensure that the first unlocking member 511 and the second joint 522 are stably abutted.

[0065] Preferably, see Figure 6 and Figure 7 The first elastic member 523 is located in the slide groove 5215 on the first base 521, and one end of the first elastic member 523 away from the second joint 522 is welded / bonded / clamped to the side wall of the slide groove 5215. In other embodiments, the first elastic member 523 can also be located outside the slide groove 5215 on the first base 521.

[0066] Preferably, see Figure 5 Each first unlocking member 511 is arranged along the vertical direction, each first mounting seat 52 is overlapped on the top side of the first unlocking member 511 through the second joint 522, and all the test cards 6 are perpendicular to the direction of the camera 1 lens. Because the test card 6 is perpendicular to the direction of the camera 1 lens, after the first mounting seat 52 is removed from the storage station 51, it is not necessary to adjust the posture of the changer 3. It is only necessary to translate the changer 3 to make the test card 6 in the first mounting seat 52 appear in the field of view of the camera 1, and the test card is facing the camera 1. This reduces the number of times the posture of the changer 3 is adjusted, and can improve the test efficiency.

[0067] It is understandable that when the lens of camera 1 is a circular lens, the direction of the lens of camera 1 is the axial direction of the lens of camera 1. When the lens of camera 1 is a square lens, the direction of the lens of camera 1 is the extension direction of the center line of the lens of camera 1.

[0068] See also Figure 4In other embodiments, each first unlocking member 511 can also be arranged in the horizontal direction, and each first mounting seat 52 is overlapped on the top side of the first unlocking member 511 through the wall of the slide groove 5215. All the test cards 6 are located in the horizontal plane. In other words, all the test cards 6 face directly downward. Because the total weight of the first mounting seat 52 and the test card 6 is large, the friction between the first seat body 521 and the first unlocking member 511 is large. After sliding the first seat body 521 until the first elastic member 523 is compressed, the friction between the first seat body 521 and the first unlocking member 511 is still greater than the elastic force of the first elastic member 523. The friction between the first seat body 521 and the first unlocking member 511 can ensure that the first elastic member 523 maintains a compressed state.

[0069] See also Figure 2 and Figure 4In the embodiment in which the first seat body 521 is provided with a first channel 5214, the alternative unit 5 further includes a backlight source and a second mounting seat 53, and the second mounting seat 53 has a second opposite side and a second mounting area. The backlight source is fixedly arranged in the second mounting area. The second mounting seat 53 is detachably arranged in the storage station 51, and the second mounting seat 53 is at least partially visible from the outside of the storage station 51, so that the second mounting seat 53 can be detachably fixedly connected to the first connector 4. A first electrical connector 32 is fixedly arranged on the opposite side 31 of the changer, and a second electrical connector corresponding to the first electrical connector 32 is arranged on the second mounting seat 53, and the backlight source is electrically connected to the second electrical connector. When the first connector 4 is fixedly connected to the second mounting seat 53, the first electrical connector 32 is connected to the second electrical connector, and the current is transmitted to the backlight source through the first electrical connector 32 and the second electrical connector. When the first connector 4 is separated from the second mounting seat 53, the first electrical connector 32 is separated from the second electrical connector. A third joint is fixedly arranged on the second opposite side, and the third joint is the same as the first joint 4. When the second mounting seat 53 is fixedly connected to the first joint 4, the groove on the third joint faces the same direction as the groove 41 on the first joint 4. In order to make the light emitted by the backlight source shine on the test card 6, the backlight source is visible from the outside of the second opposite side, and each test card 6 is visible from the outside of the first opposite side 5212 of the corresponding first mounting seat 52. When in use, the first joint 4 can be made to reach the second mounting seat 53 by using the changer 3, and then the first joint 4 is fixedly connected to the second mounting seat 53, and the second mounting seat 53 is moved away from the storage station 51. Then, the movable changer 3 makes the third joint reach one of the first mounting seats 52, and the third joint is fixedly connected to the first mounting seat 52. At this time, the second opposite side is opposite to the first opposite side 5212, and the light emitted by the backlight source shines on the test card 6 mounted on the first mounting seat 52. In this way, a backlight source is added behind the test card 6. The process of removing the test card 6 and the backlight source from the changer 3 is as follows: the movable changer 3 waits until the first mounting seat 52 fixed on the third joint returns to its position on the storage station 51, and separates the third joint from the first mounting seat 52. Then, the movable changer 3 waits until the second mounting seat 53 fixed on the first joint 4 returns to its position on the storage station 51, and separates the first joint 4 from the second mounting seat 53. In short, the operation of adding a backlight source to the back of the test card 6 can be completed by the movable changer 3, which does not rely on manual labor and can improve the test efficiency.

[0070] Exemplarily, the first electrical connector 32 and the second electrical connector are electrically connected by means of a magnetic connection or a plug-in connection.

[0071] In some embodiments, the second mounting seat 53 includes a second seat body 531, a fourth connector, and a second elastic member. The second opposite side is a side of the second seat body 531, and the second mounting area and the second electrical connector are both provided on the second seat body 531. The second seat body 531 also has a second opposite side 5311 opposite to the second opposite side. The second seat body 531 is provided with a second channel extending from the second opposite side 5311 toward the second opposite side, and the second channel is the same as the first channel 5214 and is visible from the outside of the storage station 51. The fourth connector is the same as the second connector 522, and the fourth connector can be slidably penetrated through the side wall of the second channel to enter and exit the second channel, and the second elastic member is clamped between the fourth connector and the second seat body 531 along the sliding direction of the fourth connector, and the second elastic member is used to push the fourth connector to partially slide into the second channel. A second unlocking member is fixed on the storage station 51, and the second unlocking member abuts against the side of the fourth connector away from the second elastic member to push the fourth connector out of the second channel. When in use, the movable changer 3 allows the first joint 4 to extend into the second channel on the second mounting seat 53, and allows the groove 41 on the first joint 4 to face the fourth joint. Then, the changer 3 is moved in a direction away from the second unlocking member to allow the fourth joint to be separated from the second unlocking member. The second elastic member pushes the fourth joint part to slide into the second channel and extend into the groove 41 on the first joint 4 during the process of the fourth joint being separated from the second unlocking member. In this way, the first joint 4 is fixedly connected to the second mounting seat 53, and the changer 3 can move with the second mounting seat 53. On the contrary, the movable changer 3 is moved toward the second unlocking member until the fourth joint abuts against the second unlocking member, so that the fourth joint can be withdrawn from the groove 41 on the first joint 4. The second elastic member is gradually compressed during the process of the fourth joint withdrawing from the groove 41. Then, the movable changer 3 allows the first joint 4 to move along the second channel, so that the first joint 4 can be withdrawn from the second channel, thereby completing the separation of the first joint 4 from the second mounting seat 53.

[0072] Exemplarily, the second elastic member is a spring or a rubber member.

[0073] In some embodiments, a slide groove is provided on the second base body 531, and the fourth joint is partially located in the slide groove on the second base body 531. The second unlocking member forms a slide rail adapted to the slide groove on the second base body 531 and is slidably connected to the slide groove on the second base body 531. In this way, the second base body 531 forms a sliding connection with the second unlocking member, so that the second base body 531 slides relative to the second unlocking member to control the fourth joint to enter and exit the second channel, and can ensure that the second unlocking member is stably in contact with the fourth joint.

[0074] Preferably, the second elastic member is located in the slide groove on the second base 531, and one end of the second elastic member away from the fourth joint is welded / bonded / caged to the side wall of the slide groove on the second base 531. In other embodiments, the second elastic member may also be located outside the slide groove on the second base 531.

[0075] Preferably, the second unlocking member is arranged along the vertical direction, the second mounting seat 53 is overlapped on the top side of the second unlocking member through the fourth joint, and the direction facing the backlight source is the same as the direction facing the test card 6.

[0076] In other embodiments, the second unlocking member may also be arranged in the horizontal direction, and the second mounting seat 53 is overlapped on the top side of the second unlocking member through the wall of the slide groove of the second seat body 531, and the backlight source faces directly downward. Because the total weight of the second mounting seat 53 and the backlight source is relatively large, the friction between the second seat body 531 and the second unlocking member is relatively large. After sliding the second seat body 531 until the second elastic member is compressed, the friction between the second seat body 531 and the second unlocking member is still greater than the elastic force of the second elastic member. The friction between the second seat body 531 and the second unlocking member can ensure that the second elastic member maintains a compressed state.

[0077] In some embodiments, the alternative unit 5 also includes a illuminometer and a third mounting seat 54, the third mounting seat 54 having a third opposite side and a third mounting area, the illuminometer being fixedly mounted in the third mounting area and visible from the outside of the third opposite side.

A second electrical connector corresponding to the first electrical connector 32 is provided on the third mounting seat 54, and the illuminometer is electrically connected to the second electrical connector. When the first connector 4 is fixedly connected to the third mounting seat 54, the first electrical connector 32 is magnetically connected to / pluggably connected to the second electrical connector, and the current is transmitted to the illuminometer through the first electrical connector 32 and the second electrical connector. When the first connector 4 is separated from the third mounting seat 54, the first electrical connector 32 is separated from the second electrical connector. When in use, the first joint 4 can be brought to the third mounting seat 54 by using the changer 3, and then the first joint 4 is fixedly connected to the third mounting seat 54. After that, the changer 3 is moved to the test area, and then the illumination meter in the third mounting seat 54 can be used to perform a lighting effectiveness test on the mirror rod 7. After the lighting effectiveness test is completed, the changer 3 is moved until the third mounting seat 54 fixed on the first joint 4 returns to its position on the storage station 51, and the first joint 4 is separated from the third mounting seat 54.

[0078] In some embodiments, the third mounting seat 54 includes a third seat body 541, a fifth connector and a third elastic member. The third opposite side is one side of the third seat body 541, and the third mounting area and the second electrical connector are both provided on the third seat body 541. The third seat body 541 also has a third opposite side 5411 opposite to the third opposite side. The third seat body 541 is provided with a third channel extending from the third opposite side 5411 toward the third opposite side, and the third channel is the same as the first channel 5214 and is visible from the outside of the storage station 51. The fifth connector is the same as the second connector 522, and the fifth connector can be slidably penetrated through the side wall of the third channel to enter and exit the third channel, and the third elastic member is clamped between the fifth connector and the third seat body 541 along the sliding direction of the fifth connector, and the third elastic member is used to push the fifth connector part to slide into the third channel. A third unlocking member is fixed on the storage station 51, and the third unlocking member abuts against the side of the corresponding fifth connector away from the third elastic member to push the fifth connector out of the third channel.

[0079] Exemplarily, the third elastic member is a spring or a rubber member.

[0080] In some embodiments, a slide groove is provided on the third seat body 541, and the fifth joint is partially located in the slide groove on the third seat body 541. The third unlocking member forms a slide rail adapted to the slide groove on the third seat body 541 and is slidably connected to the slide groove on the third seat body 541. In this way, the third seat body 541 forms a sliding connection with the third unlocking member, so that the third seat body 541 slides relative to the third unlocking member to control the fifth joint to enter and exit the third channel, and the third unlocking member can be ensured to be stably abutted against the fifth joint.

[0081] Preferably, the third elastic member is located in the slide groove on the third base body 541, and one end of the third elastic member away from the fifth joint is welded / bonded / caged to the side wall of the slide groove on the third base body 541.

The third mounting seat 54 is lapped on the top side of the third unlocking member through the wall of the sliding groove of the third seat body 541, and the illuminometer on the third mounting seat 54 faces directly downward. Since the total weight of the third mounting seat 54 and the illuminometer is relatively large, the frictional force between the third seat body 541 and the third unlocking member is relatively large. After sliding the third seat body 541 until the third elastic member is compressed, the frictional force between the third seat body 541 and the third unlocking member is still greater than the elastic force of the third elastic member, and the frictional force between the third seat body 541 and the third unlocking member can ensure that the third elastic member maintains the compressed state.

[0090] The present application also provides a method for testing the performance of an optical endoscope rod, which is applied to the above-mentioned optical endoscope rod performance testing system, and the method comprises the following steps:

[0091] S100 , installing and adjusting the mirror rod 7 to be tested to the mirror rod fixing frame 2 .

[0092] S200, the movable changer 3 allows the first joint 4 to extend into the first channel 5214 on the first mounting seat 52 containing the test card 6 to be tested separately, and the groove 41 on the first joint 4 is aligned with the second joint 522. The changer 3 is moved in a direction away from the first unlocking member 511 to disengage the second joint 522 from the first unlocking member 511, wherein the first elastic member 523 pushes the second joint 522 to partially slide into the first channel 5214 and extend into the groove 41 on the first joint 4 during the process of the changer 3 disengaging from the first unlocking member 511. Then, the movable changer 3 is moved until the test card 6 on the first mounting seat 52 appears in the field of view of the camera 1 to test the imaging quality of the mirror rod 7.

[0093] S300, after testing the imaging quality of the mirror rod 7 in step S200, the movable changer 3 to the second joint 522 abuts against the first unlocking member 511, and the changer 3 continues to be moved toward the first unlocking member 511 to make the second joint 522 withdraw from the groove 41 on the first joint 4, and then the first joint 4 is withdrawn from the first channel 5214 by moving the changer 3, thereby completing the separation of the first joint 4 and the first mounting seat 52.

[0094] By executing step S200 and step S300 once, the imaging quality of the scope rod 7 can be tested with one test card 6. By repeatedly executing step S200 and step S300, the test card 6 can be replaced for testing. In the optical endoscope scope rod performance testing method, step S200 and step S300 are automatically completed by the changer 3, and there is no need to rely on the tester to manually replace the test card 6, thereby improving the testing efficiency.

[0095] For the above embodiment in which each first unlocking member 511 is arranged along the vertical direction and all the test cards 6 are located in the same plane perpendicular to the direction of the lens of the camera 1, step S200 includes the following step S201, and step S300 includes the following step S301:

[0096] S201, move the changer 3 until the first joint 4 is aligned with the first channel 5214 and the groove 41 on the first joint 4 faces upward, then move the changer 3 in the horizontal direction until the first joint 4 extends into the first channel 5214 and the groove 41 on the first joint 4 faces the second joint 522. Then, move the changer 3 in the vertical upward direction until the first mounting seat 52 is separated from the first unlocking member 511. Then, translate the changer 3 until the test card 6 on the first mounting seat 52 appears in the field of view of the camera 1.

[0097] S301. After testing the imaging quality of the mirror rod 7, the movable changer 3 is moved until the second joint 522 is located directly above the first unlocking piece 511 and the slide groove 5215 on the first seat body 521 is aligned with the first unlocking piece 511. Then, the changer 3 is moved in the vertical downward direction to make the slide groove 5215 on the first mounting seat 52 sleeved outside the first unlocking piece 511 and make the second joint 522 withdraw from the groove 41 on the first joint 4. Then, the changer 3 is moved horizontally to make the first joint 4 withdraw from the first channel 5214.

[0098] In step S201, after the slide groove 5215 on the first mounting seat 52 is separated from the first unlocking member 511, it is only necessary to translate the changer 3 to make the test card 6 on the first mounting seat 52 appear in the field of view of the camera 1, which reduces the number of times the posture of the changer 3 is adjusted and can improve the test efficiency.

[0099] For the above embodiment provided with a backlight source and a second unlocking member, the above optical endoscope rod performance testing method further includes the following steps:

[0100] S400, move the changer 3 so that the first joint 4 extends into the second channel on the second mounting seat 53, and the groove 41 on the first joint 4 is aligned with the fourth joint. Move the changer 3 in a direction away from the second unlocking member to disengage the fourth joint from the second unlocking member, wherein the second elastic member pushes the fourth joint part to slide into the second channel and extend into the groove 41 on the first joint 4 during the process of the changer 3 disengaging from the second unlocking member.

[0101] S500, move the changer 3 so that the third joint on the second mounting seat 53 extends into the first channel 5214 on the first mounting seat 52 on which the test card 6 to be tested together with the backlight source is mounted, and the groove on the third joint is directly opposite to the second joint 522. Move the changer 3 in a direction away from the first unlocking member 511 to disengage the second joint 522 from the first unlocking member 511, wherein the first elastic member 523 pushes the second joint 522 to partially slide into the first channel 5214 and extend into the groove 41 on the first joint 4 during the process of the changer 3 disengaging from the first unlocking member 511. Then, move the changer 3 until the test card 6 on the first mounting seat 52 appears in the field of view of the camera 1 to test the imaging quality of the mirror rod 7.

[0102] S600, after testing the imaging quality of the mirror rod 7 in step S500, the movable changer 3 to the second joint 522 abuts against the first unlocking member 511, and the changer 3 continues to be moved toward the first unlocking member 511 to make the second joint 522 withdraw from the groove on the third joint, and then the third joint is withdrawn from the first channel 5214 by moving the changer 3, thereby completing the separation of the third joint and the first mounting seat 52.

[0103] S700, move the changer 3 until the fourth joint abuts against the second unlocking piece, continue to move the changer 3 toward the second unlocking piece to make the fourth joint withdraw from the groove 41 on the first joint 4, and then move the changer 3 to make the first joint 4 withdraw from the second channel, thereby completing the separation of the first joint 4 and the second mounting seat 53.

[0104] Through step S400 and step S500, the operation of adding a backlight source behind the test card 6 can be completed, and through step S600 and step S700, the operation of removing the test card and the backlight source from the changer 3 can be completed. These operations do not rely on manual labor, which can improve the test efficiency. Repeating step S500 and step S600 can replace the test card 6 for testing, so that different test cards 6 and backlight sources can be used to test the imaging quality of the mirror rod 7. This process also does not require the tester to manually replace the test card 6, which can improve the test efficiency.

[0105] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of protection of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the scope of protection of the present application.
