Technical Field

[0001] This application relates to the field of endoscope assembly technology, and in particular to a welding fixture for an endoscope imaging component. Background Technology

[0002] The imaging component in an endoscope comprises two circuit boards, which need to be assembled by soldering. During soldering, the two circuit boards must maintain a specific angle and accurate relative position. In related technologies, a support is used to hold the two circuit boards together to facilitate soldering. However, using a support for soldering the two circuit boards results in low yield and low soldering efficiency. Summary of the Invention

[0005] The endoscopic imaging assembly welding fixture provided in this application has a first fixing component with a support portion on the base, which facilitates the support portion to hold and constrain the first circuit board of the imaging assembly onto the first fixing component. Furthermore, a second fixing component with a limiting portion is provided on the base, and the limiting portion corresponds to the support portion, which facilitates the support portion to hold and constrain the second circuit board of the imaging assembly onto the second fixing component, and allows the second circuit board to be aligned with the part of the first circuit board to be welded. Simultaneously, by movably mounting the first fixing component on the base along a first direction and the second fixing component on the base along a second direction, the pins of the first and second circuit boards can be quickly and accurately positioned relative to the base by fine-tuning their relative positions. Therefore, during the welding process of the endoscopic imaging assembly using the welding fixture provided in this application, the two parts of the imaging assembly can be quickly and accurately positioned relative to each other, thereby improving the welding efficiency and yield of the imaging assembly.

[0024] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It includes an image sensor, optical lens, illumination source, and mechanical components. Endoscopes can be inserted into the stomach through the mouth or other natural orifices and are widely used in various medical examinations.

[0025] Reference Figure 1 , Figure 1 This application provides an endoscope imaging component. The endoscope imaging component includes a camera, a light source, and transmission lines. With the increasing demands for image clarity in disposable endoscopes, the assembly of the camera, light source, and transmission lines needs to be more compact, and the imaging component requires stable transmission performance. Therefore, a T-plate imaging component is incorporated into the endoscope, such as... Figure 1 As shown, the T-plate imaging assembly includes a first circuit board and a second circuit board. The first circuit board includes a camera, a light source, and a first rigid board. The second circuit board includes a second rigid board and a flexible board. The first and second circuit boards are typically arranged at a 90° angle and are formed by soldering the two sides together to form the T-plate imaging assembly.

[0026] In related technologies, a bracket is used to position the first and second circuit boards to facilitate soldering. However, due to the dimensional tolerances and assembly errors of the first and second circuit boards, misalignment of the solder pads on the two sides of the included angle of the first and second circuit boards can easily occur, leading to poor soldering of the first and second circuit boards.

[0027] This application provides a welding fixture for an endoscope imaging assembly, which reduces the difficulty of welding the first and second circuit boards of the imaging assembly and improves the welding efficiency and yield of the imaging assembly. (Refer to...) Figure 2 , Figure 2 A schematic diagram of the welding fixture for the endoscope imaging component provided in this application.

[0028] This application embodiment provides a welding fixture for an endoscope imaging assembly 7, including: a base 1, a first fixing component 2, and a second fixing component 3; wherein, the first fixing component 2 is movably disposed on the base 1 along a first direction X, and the first fixing component 2 has a support portion that matches the first circuit board 71 in the endoscope imaging assembly 7, the support portion being used to support the first circuit board 71; the second fixing component 3 is movably disposed on the base 1 along a second direction Y, and the second fixing component 3 has a limiting portion that matches the second circuit board 72 in the endoscope imaging assembly 7, the limiting portion corresponding to the support portion, the limiting portion being used to limit the position of the second circuit board 72 relative to the second fixing component 3, and the second direction Y and the first direction X form a preset angle.

[0029] In this embodiment, the base 1 is used to support and install other components in the welding fixture of the endoscope imaging assembly 7. The base 1 can be set as a structure with an overall shape of approximately cuboid, and mounting grooves can be provided on the base 1 to facilitate the installation of other components.

[0030] In this embodiment, the first fixing component 2 is used to support and limit the first circuit board 71 in the imaging component 7, and the first fixing component 2 can be movably disposed on the base 1. For example, the first fixing component 2 can be slidably disposed on the base 1 along the first direction X.

[0031] For example, a support portion matching the first circuit board 71 can be provided on the first fixing component 2. The shape and size of the support portion can be set according to the shape and size of the first circuit board 71 so as to support the first circuit board 71 through the support portion and restrict the first circuit board 71 relative to the first fixing component 2 at a certain position.

[0032] In this embodiment, the second fixing component 3 is used to support the second circuit board 72 in the imaging component 7 and to constrain the second circuit board 72 in a defined position. The second fixing component 3 can be movably mounted on the base 1. For example, the second fixing component 3 can be slidably mounted on the base 1 along the second direction Y. The second direction Y and the first direction X can be two mutually perpendicular directions, or two directions forming other acute angles. This embodiment does not limit the specific angle of the preset included angle between the first direction X and the second direction Y.

[0033] For example, a limiting part matching the second circuit board 72 can be provided on the second fixing component 3. The shape and size of the limiting part can be set according to the shape and size of the second circuit board 72, so as to detachably fix the second circuit board 72 on the second fixing component 3 through the limiting part.

[0034] In another example, the limiting portion corresponds to the supporting portion. That is, after the first circuit board 71 is placed on the supporting portion and the second circuit board 72 is placed on the limiting portion, the portions of the first circuit board 71 and the second circuit board 72 that need to be soldered correspond to each other. For example, the first circuit board 71 can be parallel to the plane containing the first direction X and the second direction Y, that is, at least a portion of the supporting portion can be parallel to the plane containing the first direction X and the second direction Y, while the second circuit board 72 extends along a third direction Z, that is, at least a portion of the limiting portion extends along a third direction Z, which is perpendicular to the first direction X and perpendicular to the second direction Y. In this way, the second circuit board 72 and the first circuit board 71 can be perpendicular or nearly perpendicular, and the positions of the first fixing component 2 and the second fixing component 3 relative to the base 1 can be adjusted to fine-tune the relative position between the first circuit board 71 and the second circuit board 72.

[0035] The welding fixture for the endoscope imaging assembly 7 provided in this application embodiment has a first fixing component 2 with a support portion on the base 1, which facilitates the support portion to hold and restrict the first circuit board 71 of the imaging assembly 7 on the first fixing component 2. Furthermore, a second fixing component 3 with a limiting portion is provided on the base 1, and the limiting portion corresponds to the support portion, which facilitates the support portion to hold and restrict the second circuit board 72 of the imaging assembly 7 on the second fixing component 3, and allows the second circuit board 72 to be aligned with the portion of the first circuit board 71 to be welded. Simultaneously, by movably mounting the first fixing component 2 on the base 1 along the first direction X and the second fixing component 3 on the base 1 along the second direction Y, the pins of the first circuit board 71 and the pins of the second circuit board 72 can be quickly and accurately positioned relative to the base 1 by fine-tuning the positions of the first fixing component 2 and the second fixing component 3 relative to the base 1. Therefore, when welding the endoscope imaging component 7 using the welding fixture provided in this application embodiment, the two parts of the imaging component 7 can be quickly positioned in the correct relative position, thereby improving the efficiency of welding the imaging component 7 and increasing the yield of the welding of the imaging component 7.

[0036] In some possible embodiments of this application, reference is made to Figure 3 , Figure 3 This is a schematic diagram of the structure of the first fixing component in the welding fixture for the endoscope imaging assembly provided in this application. The first fixing component 2 includes a fixing seat 21, which is movably mounted on the base 1. The bearing part includes a bearing surface 213 and a positioning post 214 disposed on the fixing seat 21. The bearing surface 213 matches one side surface of the first circuit board 71, and the positioning post 214 matches the fourth positioning hole 711 on the first circuit board 71.

[0037] In the embodiments of this application, such as Figure 2As shown, a fixing seat 21 can be provided in the first fixing component 2. The fixing seat 21 can be configured as a block-shaped or plate-shaped structure with a surface larger than the surface of the first circuit board 71. The first circuit board 71 can be supported by the fixing seat 21.

[0038] For example, one surface of the mounting base 21 can be used as a bearing surface 213. The shape of the bearing surface 213 can be set according to the shape of the first circuit board 71, for example, the bearing surface 213 can be set as a plane. The bearing surface 213 can support the first circuit board 71 and restrict the movement of the first circuit board 71 in the third direction Z. A clearance hole 211 can be provided in the bearing surface 213 to accommodate protruding components on the surface of the first circuit board 71. Mounting holes 212 can also be provided at the four corners of the mounting base 21 to facilitate the use of bolts to fix the mounting base 21 to the first adjusting assembly 4.

[0039] In another example, positioning posts 214 can be provided on the mounting base 21 and positioned on the bearing surface 213. For example, two positioning posts 214 can be provided on the bearing surface 213, each corresponding to one of the two fourth positioning holes 711 on the first circuit board 71. During the process of placing the first circuit board 71 on the bearing surface 213, the positioning posts 214 are inserted into the fourth positioning holes 711 on the first circuit board 71 to restrict the movement of the first circuit board 71 relative to the mounting base 21 along the first direction X and the second direction Y. In this way, the positioning posts 214 and the bearing surface 213 can serve as the bearing part of the first fixing component 2, supporting and restricting the first circuit board 71.

[0040] In the above embodiment, since the mounting base 21 is provided with a bearing surface 213 that matches the first circuit board 71, the first circuit board 71 can be supported by the bearing surface 213. Furthermore, the mounting base 21 is provided with a positioning post 214 that matches the fourth positioning hole 711 on the first circuit board 71. The positioning post 214 can restrict the position of the first circuit board 71 relative to the mounting base 21, thereby ensuring that the first circuit board 71 is in a defined position relative to the first fixing component 2.

[0041] In some possible embodiments of this application, such as Figure 2 As shown, the first fixing component 2 also includes a guide 22, which is disposed on the bearing surface 213, and at least two guides 22 enclose a bearing area that matches the first circuit board 71.

[0042] In this embodiment, guide members 22 can be provided on the fixing base 21, and the guide members 22 can be elongated. For example, when the first circuit board 71 is rectangular, four guide members 22 can be provided on the bearing surface 213 of the fixing base 21, forming a bearing area that conforms to the shape of the first circuit board 71. This bearing area can be larger than the first circuit board 71, meaning that when the first circuit board 71 is placed on the bearing surface 213, the first circuit board 71 may not contact the guide members 22. Alternatively, at least two guide members 22 can contact the sidewall of the first circuit board 71 to limit the position of the first circuit board 71 relative to the fixing base 21 (in this case, the positioning post 214 does not need to be provided on the bearing surface 213).

[0043] In the above embodiments, since at least two guides 22 are provided on the bearing surface 213, the bearing area can be formed by the guides 22, making it easy for the user to quickly determine the placement position of the first circuit board 71 on the fixing base 21. The guides 22 can also restrict the position of the first circuit board 71 relative to the fixing base 21 to achieve positioning of the first circuit board 71.

[0044] In some possible embodiments of this application, reference is made to Figure 4 , Figure 4 This is a schematic diagram of the base and adjustment assembly in the welding fixture for the endoscope imaging assembly provided in this application. The welding fixture for the endoscope imaging assembly 7 also includes a first adjustment assembly 4, which is disposed on the base 1, and a fixed seat 21 is disposed on the first adjustment assembly 4. The first adjustment assembly 4 is capable of moving along a first direction X.

[0045] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, a matching first adjustment component 4 can be provided for the first fixed component 2, so that the first fixed component 2 can be moved along the first direction X by the first adjustment component 4, thereby adjusting the position of the first circuit board 71 in the first direction X.

[0046] For example, the first adjustment component 4 can be configured to include a linear motor, and the first fixing component 2 can be disposed on the output shaft of the linear motor and the output shaft of the linear motor can be extended along the first direction X, so that the first fixing component 2 can be driven to move along the first direction X by the linear motor.

[0047] In the above embodiments, since the first fixing component 2 is mounted on the base 1 via the first adjusting component 4, it is convenient to adjust the position of the first fixing component 2 in the first direction X via the first adjusting component 4.

[0048] In some possible embodiments of this application, such as Figure 4As shown, the first adjustment component 4 includes a first guide rail 41, a first slider 42, and a first adjustment member 43. The first guide rail 41 is fixed to the base 1, the first slider 42 is slidably disposed on the first guide rail 41 along the first direction X, the fixed seat 21 is disposed on the first slider 42, and the first adjustment member 43 is disposed on the first guide rail 41 and connected to the first slider 42. During the process of adjusting the position of the first adjustment member 43 relative to the first guide rail 41, the first adjustment member 43 drives the first slider 42 to move relative to the first guide rail 41 along the first direction X.

[0049] In this embodiment, the first adjusting component 4 can be configured to include a first guide rail 41, a first slider 42, and a first adjusting member 43. The first guide rail 41 may have a wedge-shaped guide rail structure, and the first slider 42 may have an eyelet-tail groove that matches the wedge-shaped guide rail. The first guide rail 41 can be fixed to the base 1 with fasteners such as bolts, and the wedge-shaped guide rail can extend along the first direction X. The first slider 42 is set on the first guide rail 41 through the eyelet-tail groove and the wedge-shaped guide rail slider.

[0050] For example, the fixing base 21 can be fixed on the first slider 42 so that the first fixing component 2 can slide relative to the base 1 in the first direction X via the first slider 42 and the first guide rail 41. A first mounting groove 11 matching the first adjusting component 4 can be provided on the base 1 so that the first adjusting component 4 can be disposed in the first mounting groove 11.

[0051] In another example, a first adjusting member 43 can be provided on the first guide rail 41 to control the movement of the first slider 42 relative to the first guide rail 41. For example, the first adjusting member 43 can be a threaded screw, which is disposed on the first guide rail 41 along a first direction X through a threaded hole, and one end of the screw located inside the first guide rail 41 is connected to the first slider 42. In this way, during the rotation of the screw, the first slider 42 can be driven to slide relative to the first guide rail 41.

[0052] In another example, a first locking element 44 can be provided on the first slider 42. For example, the first locking element 44 can be a bolt. The bolt is provided on the first slider 42 through a threaded hole and extends to a position where it can abut against the first guide rail 41. By tightening the bolt, the first slider 42 can be locked relative to the first guide rail 41 or the first slider 42 can be unlocked.

[0053] In the above embodiments, since the first adjustment component 4 includes a matching first slider 42 and a first guide rail 41, the first fixing component 2 can move along the first direction X through the first slider 42 and the first guide rail 41. Furthermore, a first adjustment member 43 is provided on the first guide rail 41, which facilitates controlling the movement of the first slider 42 relative to the first guide rail 41, thereby facilitating precise adjustment of the position of the first circuit board 71 in the first direction X.

[0054] In some possible embodiments of this application, reference is made to Figure 5 and Figure 6 , Figure 5 Schematic diagram of the structure of the second fixing component in the welding fixture for the endoscope imaging assembly provided in this application Figure 1 , Figure 6 Schematic diagram of the structure of the second fixing component in the welding fixture for the endoscope imaging assembly provided in this application Figure 2 The second fixing component 3 includes a positioning seat 31 and a clamping member 32. The positioning seat 31 is movably disposed on the base 1, and the clamping member 32 is detachably connected to the positioning seat 31. The bearing part includes a positioning groove 314 disposed in the positioning seat 31 and / or the clamping member 32, and the positioning groove 314 matches at least a portion of the second circuit board 72.

[0055] In this embodiment, the second circuit board 72 can be detachably mounted in the second fixing component 3 by clamping. For example, a positioning seat 31 and a clamping member 32 can be provided in the second fixing component 3 so that the second circuit board 72 can be clamped and fixed by the cooperation of the clamping member 32 and the positioning seat 31.

[0056] For example, such as Figure 2 As shown, the positioning seat 31 can be configured as a long, rod-shaped or plate-shaped structure, extending along the second direction Y and spanning over the first fixing component 2 (along the third direction Z, the positioning seat 31 is located on the side of the first fixing component 2 away from the base 1). The clamping member 32 can be configured as a plate-shaped structure, and the clamping member 32 can be detachably connected to the positioning seat 31, so that the second circuit board 72 (extending along the third direction Z) can be clamped between the clamping member 32 and the positioning seat 31. For example, the clamping member 32 and the positioning seat 31 can be connected by a tension spring, and the clamping member 32 and the positioning seat 31 can apply a clamping force to the second circuit board 72 by the tension spring.

[0057] In another example, a positioning groove 314 matching the second circuit board 72 can be provided on the positioning base 31. Alternatively, a positioning groove matching the second circuit board 72 can be provided on the clamping member 32. Or, positioning grooves matching the second circuit board 72 can be provided on both the positioning base 31 and the clamping member 32. In this way, the second circuit board 72 can be accommodated within the positioning groove 314 between the clamping member 32 and the positioning base 31.

[0058] In another example, a first extension segment 313 can be provided on the positioning base 31. The first extension segment 313 extends from the positioning base 31 in a third direction Z and extends toward the first fixing component 2. Correspondingly, a second extension segment 322 corresponding to the first extension segment 313 can be provided on the clamping member 32. The second extension segment 322 extends from the clamping member 32 in a third direction Z and extends toward the first fixing component 2. The width of the first extension segment 313 in the second direction Y is less than the length of the positioning base 31 and greater than the width of the second circuit board 72. The width of the second extension segment 322 in the second direction Y is less than the length of the clamping member 32 and greater than the width of the second circuit board 72. For example, the widths of both the first extension segment 313 and the second extension segment 322 can be 1.2 to 2 times the width of the circuit board. Positioning grooves 314 can be provided on both the first extension segment 313 and the second extension segment 322. Thus, after the second circuit board 72 is clamped between the positioning seat 31 and the clamping member 32, the first extension 313 and the second extension 322 can also provide clamping force to the end of the second circuit board 72 facing the first circuit board 71, and the width of the first extension 313 and the second extension 322 is small, thereby reducing the obstruction of the soldering area between the first circuit board 71 and the second circuit board 72.

[0059] In the above embodiments, since the clamping member 32 and the positioning seat 31 are detachably connected, the second circuit board 72 can be clamped and fixed between the clamping member 32 and the positioning seat 31. Furthermore, the clamping member 32 and / or the positioning seat 31 are provided with positioning grooves 314, which can accommodate the second circuit board 72 and provide space for the devices on the second circuit board 72, thereby reducing the risk of the clamping member 32 and the positioning seat 31 squeezing the devices on the second circuit board 72.

[0060] In some possible embodiments of this application, such as Figure 6 As shown, at least one of the positioning base 31 and the clamping member 32 is provided with a magnetic element, and the positioning base 31 and the clamping member 32 are detachably connected by the magnetic element.

[0061] In this embodiment, the clamping member 32 and the positioning base 31 can be detachably connected by magnetic attraction. For example, a first magnetic element 34 can be provided on the positioning base 31, and a second magnetic element 35 can be provided on the clamping member 32. Both the first magnetic element 34 and the second magnetic element 35 can be permanent magnets, such as neodymium iron boron magnets or samarium cobalt magnets. The first magnetic element 34 and the second magnetic element 35 can generate an attractive force when they are close to each other. Alternatively, a magnetic element can be provided on one of the positioning base 31 and the clamping member 32, while the other of the positioning base 31 and the clamping member 32 can be made of a material such as iron or steel that can be attracted by a magnet.

[0062] For example, a first positioning element 33 can be provided on the positioning base 31. The first positioning element 33 can be a cylinder, which is fixed on the side of the positioning base 31 facing the clamping element 32. Correspondingly, a third positioning hole 321 matching the cylinder can be provided on the clamping element 32, so that the clamping element 32 and the positioning base 31 can be positioned by the cooperation of the hole and the cylinder. Alternatively, the first positioning element 33 can be provided on the clamping element 32, and the third positioning hole 321 can be provided on the positioning base 31.

[0063] In the above embodiments, since at least one of the positioning base 31 and the clamping member 32 is provided with a magnetic element, the clamping member 32 can be fixedly connected to the positioning base 31 by the magnetic attraction force generated by the magnetic element, and it is also convenient to separate the clamping member 32 from the positioning base 31 by applying an external force to the clamping member 32.

[0064] In some possible embodiments of this application, the welding fixture for the endoscope imaging assembly 7 further includes a second adjustment assembly 5, which is disposed on the base 1 and the positioning seat is disposed on the second adjustment assembly 5. The second adjustment assembly 5 is capable of generating movement along the second direction Y.

[0065] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, a matching second adjustment component 5 can be provided for the second fixing component 3, so that the second fixing component 3 can be moved along the second direction Y by the second adjustment component 5, thereby adjusting the position of the second circuit board 72 in the second direction Y.

[0066] For example, the second adjusting component 5 can be configured to include a ball screw assembly. The nut of the ball screw assembly can be slidably mounted on the base 1 along the second direction Y, and the positioning seat 31 of the second fixing component 3 can be fixedly connected to the nut. The lead screw of the ball screw assembly can be rotatably mounted on the base 1. Then, by rotating the lead screw, the nut can drive the positioning seat 31 to move along the second direction Y.

[0067] In the above embodiments, since the second fixing component 3 is mounted on the base 1 via the second adjusting component 5, it is convenient to adjust the position of the second fixing component 3 in the second direction Y via the second adjusting component 5.

[0068] In some possible embodiments of this application, the second adjustment component 5 includes a guide component 51 and an adjustment component 52 both disposed on the base 1. Along the second direction Y, the guide component 51 and the adjustment component 52 are respectively located on both sides of the first fixing component 2. One end of the positioning seat 31 is connected to the guide component 51, and the other end of the positioning seat 31 is connected to the adjustment component 52. By adjusting the position of the adjustment component 52 relative to the base 1 along the second direction Y, the positioning seat 31 can be moved along the second direction Y through the guide component 51.

[0069] In this embodiment, the positioning seat 31 in the second fixing component 3 is relatively long and spans across the top of the first fixing component 2. Therefore, the second adjusting component 5 can be configured to include a guide component 51 and an adjusting component 52. Along the second direction Y, the guide component 51 can be located on one side of the first fixing component 2, and the adjusting component 52 can be located on the other side of the first fixing component 2, so that the positioning seat 31 can be movably mounted on the base 1 along the second direction Y by the guide component 51 and the adjusting component 52.

[0070] For example, such as Figure 4 As shown, the guide assembly 51 can be configured to include a matching second guide rail 511 and a second slider 512. The second guide rail 511 can be fixed to the base 1 along the second direction Y, so that the second slider 512 can slide along the second guide rail 511 in the second direction Y. For example, a second positioning member 513 can be provided on the second slider 512. The second positioning member 513 can be cylindrical, and correspondingly, such as... Figure 5 As shown, a first positioning hole 311 matching the second positioning member 513 can be provided at one end of the positioning seat 31, so that the movement of the positioning seat 31 relative to the second slider 512 can be restricted through the cooperation of the first positioning hole 311 and the second positioning member 513. The positioning seat 31 and the second slider 512 can be fixedly connected by fasteners such as bolts, or they can be detachably connected by magnetic components. For example, a third magnetic component 36 can be provided on the positioning seat 31, and correspondingly, a fourth magnetic component 514 can be provided on the second slider 512. Both the third magnetic component 36 and the fourth magnetic component 514 can be permanent magnets such as magnets, or electromagnets, etc.

[0071] Another example, such as Figure 4As shown, the adjustment assembly 52 can be configured to include a third guide rail 521, a third slider 522, and a third adjusting member 523. The third guide rail 521 can be fixed to the base 1 along the second direction Y, and the third slider 522 can be slidably connected to the third guide rail 521. The third adjusting member 523 can be provided on the third guide rail 521 to control the movement of the third slider 522 relative to the third guide rail 521 along the second direction Y. For example, the third adjusting member 523 can be a threaded screw, which is provided on the third guide rail 521 along the second direction Y through a threaded hole, and one end of the screw located inside the third guide rail 521 is connected to the third slider 522. In this way, during the rotation of the screw, the third slider 522 can be driven to slide relative to the third guide rail 521. A second mounting groove 12 matching the adjustment assembly 52 can be provided on the base 1 to accommodate and install the adjustment assembly 52.

[0072] In another example, a third locking element 524 can be provided on the third slider 522. For example, the third locking element 524 can be a bolt, which is provided on the third slider 522 through a threaded hole and extended to a position where it can abut against the third guide rail 521. By turning the bolt, the third slider 522 can be locked relative to the third guide rail 521 or the third slider 522 can be unlocked.

[0073] Another example is that a third positioning element 525 can be provided on the third slider 522. The third positioning element 525 can be a cylinder, and correspondingly, such as Figure 5 As shown, a second positioning hole 312 matching the third positioning member 525 can be provided at the other end of the positioning seat 31, so that the movement of the positioning seat 31 relative to the third slider 522 can be restricted through the cooperation of the second positioning hole 312 and the third positioning member 525. The positioning seat 31 and the third slider 522 can be fixedly connected by fasteners such as bolts, or they can be detachably connected by magnetic components. For example, a fifth magnetic component 37 can be provided on the positioning seat 31, and correspondingly, a sixth magnetic component 526 can be provided on the third slider 522. The fifth magnetic component 37 and the sixth magnetic component 526 can be permanent magnets such as magnets, or electromagnets, etc. In this way, the positioning seat 31 and the second adjustment assembly 5 can be detachably connected by magnetic components, which facilitates the removal or installation of the second fixing component 3 from the second adjustment assembly 5.

[0074] In another example, the guide component 51 may be omitted, and only the adjustment component 52 may be provided to movably position the positioning seat 31 on the base 1 along the second direction Y. In this case, the positioning seat 31 can be cantilevered on the adjustment component 52 so that the positioning seat 31 extends above the first fixing component 2, thereby fixing the second circuit board 72 above the first circuit board 71.

[0075] In the above embodiments, since the second adjustment component 5 includes a guide component 51 and an adjustment component 52, the guide component 51 and the adjustment component 52 can be respectively arranged on both sides of the first fixing component 2 along the second direction Y. Thus, the guide component 51 and the adjustment component 52 can provide support and installation points for the positioning seat 31 from both ends, which is beneficial to make the positioning seat 31 move stably relative to the base 1 along the second direction Y.

[0076] In some possible embodiments of this application, reference is made to Figure 7 , Figure 7 This is a schematic diagram of the base in the welding fixture for the endoscope imaging assembly provided in this application. The welding fixture for the endoscope imaging assembly 7 also includes a base 6, which has a receiving groove 61 that matches the base 1. The base 1 can be held in the receiving groove 61 to limit the position of the base 1.

[0077] In the embodiments of this application, such as Figure 2 and Figure 7 As shown, a base 6 can be provided on the base 1 to restrict the base 1 at the required angle and position so as to facilitate the soldering of the first circuit board 71 and the second circuit board 72.

[0078] For example, the base 6 can be configured as a block structure, and a receiving groove 61 matching the base 1 can be provided on the base 6. For instance, the receiving groove 61 can be configured as a V-shaped groove, with its two walls extending along a first direction X and a third direction Z, respectively. The first direction X and the third direction Z are perpendicular to each other, and both directions X and Z can form a 45° angle with the horizontal plane. Thus, after the base 1 is placed in the receiving groove 61 of the base 6, the base 1 can be held in an inclined position within the receiving groove 61, thereby allowing the second circuit board 72 to form a 45° angle with the horizontal plane, facilitating observation of the pins to be soldered.

[0079] Another example is that a clearance notch 62 can be provided on the base 6. For example, the clearance notch 62 can be provided on one side wall of the receiving groove 61. In this way, after the base 1 is placed into the receiving groove 61, a part of the base 1 can be exposed through the clearance notch 62, making it easy to put the base 1 in and out through the clearance notch 62.

[0080] In the above embodiment, since a base 6 matching the base 1 is provided, the base 1 can be kept in an inclined state by the base 6, so that the first circuit board 71 and the second circuit board 72 fixed in the welding fixture of the endoscope imaging assembly 7 can be kept in an inclined state, which makes it easier to observe the pins to be welded and also facilitates the welding operation.
