[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] See also Figures 1 to 7 As shown, one embodiment of the present invention provides an endoscope curved portion glue coating device 100, which includes a workbench 10, a positioning assembly 20, a glue coating assembly 30, and a visual marker 40. The workbench 10 is equipped with a clamping assembly 11 and a first actuator. The clamping assembly 11 is used to clamp the endoscope barrel, and the first actuator is used to drive the clamping assembly 11 to rotate the endoscope barrel. The positioning assembly 20 is mounted on the workbench 10 and includes a first positioning mechanism 21 and a second positioning mechanism 22, which are sequentially arranged along the rotation axis of the clamping assembly 11 and are used to position the end of the endoscope barrel. The glue coating assembly 30 includes a first sliding frame 31 and a glue coating needle 32. The glue coating needle 32 is mounted on the first sliding frame 31 and drives the glue coating needle 32 to move along the rotation axis of the clamping assembly 11. The glue coating needle 32 has a glue coating head 321. The visual marker 40 is arranged on the first sliding frame 31. The visual marker 40 is used to emit visible light. The visible light and the glue coating head 321 are located on the same straight line. The straight line where the visible light and the glue coating head 321 are located is perpendicular to the rotation axis of the clamping assembly 11. The visible light is used to mark the coating position of the glue coating head 321 on the endoscope tube.

[0026] Specifically, the workbench 10 is the base of the entire device, on which the clamping assembly 11 and the first driver are mounted, enabling the endoscope barrel to be fixed and rotated. The positioning assembly 20 is positioned along the rotation axis of the clamping assembly 11, allowing the end of the endoscope barrel to be precisely located, providing a reference for the glue application process.

[0027] Among them, the first positioning mechanism 21 is arranged between the second positioning mechanism 22 and the clamping assembly 11. The first positioning mechanism 21 is used to position the end of the mirror tube when gluing is applied to the head area of ​​the bent part of the mirror tube, and the second positioning mechanism 22 is used to position the end of the mirror tube when gluing is applied to the tail area of ​​the bent part of the mirror tube.

[0028] The glue coating assembly 30 is primarily used to apply glue to both ends of the curved endoscope tube (the head and tail regions). During the glue coating process, the first actuator rotates the clamping assembly 11 and the endoscope tube mounted thereon. Simultaneously, the first sliding frame 31 drives the glue coating needle 32 along the rotation axis of the clamping assembly 11, evenly coating the curved endoscope section with glue using the glue coating tip 321 of the glue coating needle 32.

[0029] Furthermore, the visual marker 40 moves synchronously with the gluing head 321. This real-time marking with visible light solves the difficulty in positional confirmation during the gluing process, a problem previously encountered in related techniques, and helps improve gluing accuracy. Before gluing, the visual marker 40 illuminates the surface of the lens tube, forming a bright line perpendicular to the axis of rotation, visually marking the starting position of the gluing head 321 and the gluing width. The operator monitors the relative position of the marker and the lens tube in real time, either visually or using an industrial camera. This allows for dynamic adjustment of gluing parameters (such as gluing width, rotation speed of the clamping assembly 11, and movement speed of the gluing needle 32) to achieve improved gluing accuracy.

[0030] Furthermore, the visual marker 40 features a closed-loop calibration function. Using visible light, it marks the starting position of the glue applicator 321. This function also calibrates the glue application position, correcting for positional deviations caused by mechanical vibration (e.g., offset caused by the rotation of the clamping assembly 11), thereby improving glue application accuracy. Specifically, the visual marker 40 uses visible light to create a starting position mark on the lens tube surface. The operator monitors the marked position using an industrial camera and can manually fine-tune the position or the system can automatically correct the mark.

[0031] In summary, the endoscope curved part gluing device provided in the embodiment of the present invention can achieve precise positioning of the mirror tube during the gluing process through the mutual cooperation of the clamping assembly, the first positioning mechanism and the second positioning mechanism; and the visible light emitted by the visual marker can monitor and mark the moving position of the gluing head in real time, thereby achieving precise control of the gluing process, which helps to improve the gluing accuracy and quality.

[0032] In this embodiment, the bottom of the workbench 10 is further provided with walking wheels, which can facilitate the movement of the endoscope bending part gluing device.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the clamping assembly 11 includes a catheter frame 111 and a three-jaw chuck 112. The three-jaw chuck 112 is located on a side of the catheter frame 111 near the positioning assembly 20. The catheter frame 111 is in driving connection with the output end of a first driver. The first driver drives the three-jaw chuck 112 to rotate via the catheter frame 111, thereby rotating the endoscope tube held by the three-jaw chuck 112. Furthermore, the three-jaw chuck can conveniently secure endoscope tubes of different sizes, meeting the needs of endoscope tubes of different sizes.

[0034] Furthermore, the three-jaw chuck can be configured as a pneumatic chuck, and the jaws are detachably connected to the fixed plate, making maintenance and replacement easier. Furthermore, the jaw tips are made of wear-resistant material and have a rust-proof surface treatment for increased durability.

[0035] Furthermore, the inner wall of the jaws of the three-jaw chuck is provided with protective silicone, which can reduce the possibility of damage to the endoscope tube.

[0036] During operation, the operator first inserts the endoscope tube from one end of the catheter rack 111, and allows it to move smoothly along the inside of the catheter rack 111 until the endoscope tube reaches the position of the first positioning mechanism 21 or the second positioning mechanism 22 of the positioning assembly 20, thereby fixing the tube length. Then, the three-jaw chuck 112 can be started to move the three jaws toward the center at the same time to tightly clamp the endoscope tube.

[0037] like Figure 2 and Figure 3As shown, in this application, for the convenience of description, the direction of the rotation axis of the clamping assembly 11 is referred to as the X direction, the direction of the straight line perpendicular to the rotation axis of the clamping assembly 11 on the horizontal plane is referred to as the Y direction, and the height direction of the workbench 10 is referred to as the Z direction. The first sliding frame 31 includes a first sliding unit 311, a second sliding unit 312, and a third sliding unit 313. The first sliding unit 311 is arranged along the Y direction, that is, the first sliding unit 311 can slide linearly along the direction perpendicular to the rotation axis of the clamping assembly 11 on the horizontal plane; the second sliding unit 312 is arranged along the X direction, and the third sliding unit 313 is arranged along the Z direction. The glue needle 32 and the visual marker 40 are arranged on the third sliding unit 313, so that the glue needle 32 can be accurately positioned and moved in the X, Y, and Z directions.

[0038] During the gluing operation, through the cooperation of the first sliding unit 311 and the second sliding unit 312, the gluing needle 32 can accurately reach the top of the endoscope tube that needs to be glued, and then the distance between the gluing needle 32 and the tube is controlled by the lifting and lowering movement of the third sliding unit 313 to achieve uniform and accurate gluing. The setting of the visual marker 40 further improves the accuracy and convenience of the operation. The visual marker 40 is also installed on the third sliding unit 313. It can move in three directions with the gluing needle 32. During the operation, it provides the operator with an intuitive reference mark by emitting a visible light beam, etc., to help the operator judge the position and perform operations more accurately, ensuring the high-quality completion of the entire gluing process and other related operations.

[0039] Furthermore, during the gluing process, the first actuator rotates the clamping assembly and the endoscope tube above it, while the gluing needle continuously releases granular glue, precisely controlling the volume of glue. This ensures uniform glue thickness, avoids the unevenness and errors caused by manual gluing, and significantly improves gluing quality. Furthermore, the gluing needle is replaceable, making it easy to replace and maintain according to the type of glue and the amount of glue applied.

[0040] Furthermore, the first sliding unit 311, the second sliding unit 312 and the third sliding unit 313 can all include a slide rail, a slider and a fourth driver, and the slider is transmission-connected to the output end of the fourth driver to drive the slider to move along the slide rail to achieve position adjustment of the glue coating needle 32 and the visual marker 40.

[0041] Optionally, the fourth driver can be configured as a cylinder, an oil cylinder, a motor or other components.

[0042] like Figure 3As shown, in some embodiments, the visual marker 40 includes a visible light laser 41 , which is configured to emit a visible light beam to project a straight line onto the plane where the rotation axis of the clamping assembly 11 is located.

[0043] Optionally, the visible light beam is set to a red beam. The red beam has a high degree of recognition within the visible light range and can stand out in various complex environmental backgrounds. Even if there is interference from other light sources or smoke, dust, etc. generated by the operation of the equipment, the red beam can still be clearly perceived by the operator.

[0044] like Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, the first positioning mechanism 21 includes a fixing frame 211, a positioning rod 212 and a second driver 213. The fixing frame 211 is arranged on the workbench 10, the second driver 213 is arranged on the fixing frame 211, and the positioning rod 212 is provided with a slot 2121. The positioning rod 212 is arranged at the output end of the second driver 213. The second driver 213 is used to drive the positioning rod 212 to rotate so that the slot 2121 has a first position on the rotation axis of the clamping assembly 11 relative to the clamping assembly 11. When the slot 2121 is in the first position, the end of the endoscope tube is located in the slot 2121 to position the length of the endoscope tube extending relative to the clamping assembly 11.

[0045] Specifically, the fixed frame 211 is the supporting base of the first positioning mechanism 21, which is arranged on the workbench 10. The second driver 213 is arranged on the fixed frame 211. The second driver 213 drives the positioning rod 212 to rotate so that the slot 2121 has a first position and a second position, thereby realizing the angle adjustment of the positioning rod 212.

[0046] During operation, the second driver 213 drives the positioning rod 212 to rotate to the first position, where the slot 2121 is located on the rotation axis of the clamping assembly 11. After the endoscope tube extends from the catheter holder 111 and the clamping assembly 11, its end enters the slot 2121, thereby positioning the extension length of the endoscope tube, thereby improving the accuracy of the starting position of the glue application process. When the second driver 213 drives the positioning rod 212 to rotate to the second position, the slot 2121 deviates from the rotation axis of the clamping assembly 11.

[0047] Furthermore, the slot 2121 has a first surface 2122 and a second surface 2123 that are perpendicular to each other. The first surface 2122 is parallel to the rotation axis of the clamping assembly 11 and is used to receive the endoscope barrel and abut against the outer circumference of the endoscope barrel. The second surface 2123 is perpendicular to the rotation axis of the clamping assembly 11 and is used to abut the axial end of the endoscope barrel.

[0048] When the endoscope tube falls into the slot 2121, the first surface 2122 receives the tube, ensuring that it is aligned with the rotation axis of the clamping assembly 11, while the second surface 2123 abuts against the end of the tube to determine the tube's position relative to the rotation axis of the clamping assembly 11. In other words, when the end of the tube contacts the second surface 2123, it indicates that the tube has reached the predetermined axial position, thereby enabling precise control of the tube's extended length.

[0049] Furthermore, the positioning rod 212 includes a rod body 2124 and a positioning sleeve 2125, with a slot 2121 provided in the positioning sleeve 2125. The second actuator 213 can be configured as a rotary cylinder or motor, with its rotation axis parallel to the rotation axis of the clamping assembly 11. The positioning rod 212 extends radially from the second actuator 213 to the rotation axis of the clamping assembly 11. The positioning sleeve 2125 reduces friction with the endoscope barrel, reducing the risk of damage to the barrel during positioning.

[0050] like Figure 4 、 Figure 5 and Figure 7 As shown, in some embodiments, the second positioning mechanism 22 includes a second sliding frame 221, a receiving rod 222 and a third driver 223. The second sliding frame 221 is arranged on the workbench 10, the third driver 223 is arranged on the second sliding frame 221, and the receiving rod 222 is provided with a positioning groove 2221, which is used to receive the endoscope tube; the receiving rod 222 is arranged at the output end of the third driver 223, and the third driver 223 drives the receiving rod 222 to move so that the positioning groove 2221 is located on the rotation axis of the clamping assembly 11 or deviates from the rotation axis of the clamping assembly 11.

[0051] Specifically, a positioning groove 2221 is provided on the receiving rod 222. The shape and size of the positioning groove 2221 are designed according to the outer diameter and shape of the endoscope tube. For example, the positioning groove 2221 can be set to a semicircular or V-shaped structure, so that it can achieve a good fit with the outer circumference of the tube and provide stable support and positioning.

[0052] Furthermore, the second sliding frame 221 includes a fourth sliding unit 2211, a fifth sliding unit 2212 and a sixth sliding unit 2213. The fourth sliding unit 2211 is extended along the X direction, the fifth sliding unit 2212 is extended along the Y direction, and the sixth sliding unit 2213 is extended along the Z direction. The receiving rod 222 can be arranged on the sixth sliding unit 2213 to realize the adjustment of the receiving rod 222 at multiple angles, so that the positioning groove 2221 can be accurately moved to the rotation axis of the clamping assembly 11.

[0053] It should be noted that the second sliding frame 221 is similar to the first sliding frame 31, and the fourth sliding unit 2211, the fifth sliding unit 2212, and the sixth sliding unit 2213 are all provided with slide rails and drivers, wherein the third driver 223 mentioned above can be provided on the sixth sliding unit 2213. Optionally, the third driver 223 can be provided as a component such as an electric push rod, a cylinder, or a servo motor.

[0054] like Figure 7 As shown, in some embodiments, the second positioning mechanism 22 further includes two auxiliary wheels 224, which are rotatably disposed on the receiving rod 222. The two auxiliary wheels 224 are respectively located on both sides of the second positioning groove 2221, and the auxiliary wheels 224 are used to receive the endoscope tube.

[0055] Specifically, the receiving rod 222 is provided with a mounting hole, into which the axle of the auxiliary wheel 224 can be inserted, thereby achieving the installation and fixation of the auxiliary wheel 224. When the receiving rod 222 positions the end of the endoscope tube, since the glue is applied to the tail area of ​​the bent portion at this time, the protruding length of the endoscope tube is relatively long. The receiving rod 222 can support the endoscope tube, thereby preventing the endoscope tube from bending, etc., which affects the glue application accuracy. In addition, the auxiliary wheel 224 can maintain contact with the outer circumference of the tube through the wheel surface, and the auxiliary wheel 224 can reduce the friction between the tube and the receiving rod 222 by utilizing its own rotation, thereby reducing the wear on the tube surface.

[0056] At the same time, two auxiliary wheels 224 are located on either side of the second positioning groove 2221, forming a symmetrical support structure. This structure constrains and supports the scope tube from two directions, effectively preventing radial deviation or shaking of the scope tube during positioning, thereby improving the stability and accuracy of scope tube positioning. Furthermore, the support provided by the auxiliary wheels 224 disperses the weight of the scope tube, reducing the pressure on the second positioning groove 2221 and extending the service life of the positioning groove 2221 and the receiving rod 222.

[0057] Furthermore, the second positioning mechanism 22 also includes a fixed support 225 and an end abutment rod 226 located on the fixed support 225. The end abutment rod 226 is used to abut the end of the endoscope tube when the endoscope tube is located in the positioning groove 2221 to limit the extension length of the endoscope tube relative to the clamping assembly 11.

[0058] The fixed support 225 is provided on the fifth sliding unit 2212. When the endoscope tube is placed in the positioning groove 2221, the end abutment rod 226 plays a crucial positioning role. Its end tightly abuts against the end of the endoscope tube, and through a pre-set positional relationship, it accurately defines the extension length of the endoscope tube relative to the clamping assembly 11, thereby achieving precise positioning of the starting position of glue coating at the tail of the endoscope tube's curved portion.

[0059] Specifically, when inserting the endoscope tube into the positioning slot 2221, the operator slowly pushes the tube until its end gradually approaches the end abutment rod 226. When the end of the tube fully contacts the end abutment rod 226, the tube has reached its predetermined elongation. At this point, the clamping assembly 11 can securely clamp the tube, preparing for subsequent gluing and assembly steps.

[0060] In this embodiment, a threaded hole can be provided on the fixed support 225, and a corresponding external thread can be processed on the end abutment rod 226. By tightening the two, the end abutment rod 226 and the fixed support 225 can be moved to achieve fine adjustment of the positioning of the end of the endoscope tube.

[0061] like Figure 3 As shown, in some embodiments, the endoscope curved portion gluing device 100 further includes a curing component 50, the curing component 50 includes a light curing unit 51, the light curing unit 51 is arranged on the first sliding frame 31, the light curing unit 51 moves synchronously with the gluing head 321, and the light emitted by the light curing unit 51 is directed toward the endoscope tube clamped by the clamping component 11.

[0062] Specifically, the light-curing unit 51 is mounted on the third sliding unit 313 and is the core component of the curing assembly 50. It primarily consists of a light source, a reflector, a condenser lens, and a control system. The light source is a key component for generating the light required for curing and can be either an ultraviolet (UV) light source or a visible light source.

[0063] When the glue coating head 321 moves along the axial direction of the clamping component 11 to coat the endoscope tube with glue, the curing component 50 also moves synchronously to cure the glue on the endoscope tube synchronously, which not only improves the glue coating quality but also improves production efficiency.

[0064] In addition, the use process of the endoscope curved part gluing device provided by the embodiment of the present invention includes the following steps: first, the endoscope tube is passed through the catheter holder into the three-jaw chuck, and then the three-jaw chuck can preliminarily fix the tube, and then the second driver can drive the positioning rod to rotate so that the slot is located on the rotation axis of the clamping component, and then the endoscope tube is fixed again by the three-jaw chuck to achieve positioning of the head area of ​​the curved part of the endoscope tube; then, the visual marker is started, and the gluing port of the gluing needle is illuminated by red visible light to monitor the gluing position in real time and accurately locate the starting and ending positions of the gluing. At the same time, the gluing component is controlled to accurately adjust the amount of glue at the gluing port to ensure the quality of the gluing.

[0065] After completing the gluing of the head area of ​​the bend, release the three-jaw chuck, and move the receiving rod to the positioning groove on the rotation axis of the clamping assembly through the second sliding frame. The operator moves the endoscope tube, and places the end of the tube in the positioning groove and the end of the tube abuts against the end abutment rod. At this time, the position to be glued in the tail area of ​​the bend is moved into place, the three-jaw chuck can be controlled to lock, and then the gluing assembly and the visual marker are controlled to work again to complete the gluing of the tail area of ​​the bend.

[0066] Finally, the glue on the bent portion can be cured by the curing component to complete the entire gluing process. Of course, it is conceivable that during the gluing process of the gluing component, the curing component can also simultaneously cure the glue to improve the gluing efficiency.

[0067] In addition, an embodiment of the present invention also provides an endoscope curved part gluing system, which includes the endoscope curved part gluing device 100, a glue supply device and a power device provided in any of the above embodiments. The glue supply device is used to provide the colloid to be coated to the gluing component 30, and the power device can provide power to each driver in the endoscope curved part gluing device 100.
