Description

Technical Field

[0001] This application relates to the field of endoscopic device technology, specifically to an endoscopic module and a testing mechanism. Background Technology

[0002] In existing endoscopes, the tail sleeve and tip are mostly injection molded and connected by riveting technology. The camera module, guide with working channel and snake tube are connected to the tip by potting glue. The assembly is cumbersome and difficult, resulting in low assembly efficiency and accuracy. Utility Model Content

[0003] In view of the above, it is necessary to provide an endoscope module and a testing mechanism to improve assembly efficiency and assembly accuracy.

[0004] This application provides an endoscope module, including: The tip is provided with a detection through hole; A camera assembly includes a lens and a circuit board unit. The lens includes a lens barrel and at least one lens disposed within the lens barrel. The lens barrel is embedded in the tip and is integral with the tip. The optical axis of the lens is parallel to the axial direction of the detection through hole. The circuit board unit is disposed correspondingly to the lens along the optical axis of the lens. A tail sleeve, spaced apart from the tip along the optical axis of the lens, is fitted onto the circuit board unit; and The encapsulating adhesive is connected to the tip, the tail sleeve, and the circuit board unit respectively, and is sleeved on the circuit board unit.

[0005] The aforementioned endoscope module integrates the tip and lens, which reduces the assembly difficulty and deformation of the endoscope module during assembly, thereby improving the assembly efficiency and accuracy of the endoscope module.

[0006] In some embodiments, the tip includes: The molded body is an integral structure with the lens barrel; The mounting body is connected to one end of the molded body and has the detection through hole. Along the direction from the molded body to the mounting body, the molded body and the mounting body have a stepped structure.

[0007] Therefore, the stepped structure of the molded body and the mounting body is beneficial to improving the connection stability between the encapsulating adhesive and the tip.

[0008] In some embodiments, the surface of the molded body facing away from the lens barrel and the surface of the mounting body facing away from the detection through hole are both arc-shaped surfaces.

[0009] Therefore, by adopting the above settings, the connection strength between the encapsulating adhesive and the molded body and the mounting body can be increased, and the connection stability between the encapsulating adhesive and the tip can be further improved.

[0010] In some embodiments, the encapsulating adhesive includes: The first colloid is connected to the surface of the molded body opposite to the lens, the surface of the mounting body opposite to the detection through hole, and the circuit board unit, respectively. The second colloid is sleeved on the circuit board unit, and the second colloid is connected to the surface of the molding body facing the tail sleeve, the surface of the mounting body facing the tail sleeve, the surface of the tail sleeve facing the tip, the first colloid, and the circuit board unit respectively.

[0011] Therefore, by setting it up as described above, the first adhesive and the tip are nested together, and the first and second adhesives are arranged sequentially along the axial direction of the detection through hole, which can improve the connection stability between the encapsulating adhesive and the tip.

[0012] In some embodiments, along the axial direction of the detection through-hole, the length of the first colloid is greater than the length of the second colloid.

[0013] Therefore, the above settings enable the encapsulating adhesive to fix both the tip and the tail sleeve while also achieving a miniaturized design.

[0014] In some embodiments, the surface of the second colloid facing the tail sleeve has an extension, and the surface of the tail sleeve facing the second colloid has a retaining portion, with the extension and the retaining portion engaging in a slotted fit.

[0015] Therefore, the connection accuracy and strength between the encapsulating adhesive and the tail sleeve can be improved by the cooperation of the extension and the retaining part in the slot.

[0016] In some embodiments, the endoscope module further includes: The snake tube is connected to the end of the tail sleeve away from the encapsulating adhesive and is sleeved on the circuit board unit.

[0017] Therefore, the use of a snake tube can improve the ease of movement of the endoscope module by manual or external components.

[0018] In some embodiments, the endoscope module further includes: An inlet component is inserted into the tail sleeve and the detection through hole to allow the detection component to pass through.

[0019] Therefore, the guide can guide the test piece into the test hole, thereby improving the efficiency of the test piece in conjunction with the endoscope module for testing.

[0020] In some embodiments, the endoscope module further includes: An illumination element is connected to the end of the tip that is away from the tail sleeve.

[0021] Therefore, illumination can be provided to the endoscope module to improve the clarity of the images acquired by the endoscope module.

[0022] This application embodiment also provides a testing organization, including: The aforementioned endoscopic module; The testing component is inserted into the testing through hole when the testing mechanism is in operation.

[0023] The endoscope module in the aforementioned testing mechanism integrates the tip and lens, which reduces the assembly difficulty of the endoscope module and minimizes deformation during assembly, thereby improving the assembly efficiency and accuracy of the testing mechanism.

In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] Please see Figure 1 and Figure 2 This application provides an endoscope module 100, including a tip 110, a camera assembly 120, a tail sleeve 130, and encapsulating adhesive 140. The tip 110 has a detection through-hole 110a. The camera assembly 120 includes a lens 121 and a circuit board unit 122. The lens 121 includes a lens barrel 1211 and at least one lens element (not shown) disposed within the lens barrel 1211. The lens barrel 1211 is embedded in the tip 110 and is integrally formed with the tip 110. The optical axis of the lens 121 is parallel to the axial direction of the detection through-hole 110a. The circuit board unit 122 is correspondingly disposed with respect to the lens 121 along the optical axis of the lens 121. The tail sleeve 130 is spaced apart from the tip 110 along the optical axis of the lens 121 and is fitted onto the circuit board unit 122. The encapsulating adhesive 140 is connected to the tip 110, the tail sleeve 130 and the circuit board unit 122 respectively, and is sleeved on the circuit board unit 122.

[0032] It should be noted that the circuit board unit 122 is a unit that works with the lens 121 to acquire images, including but not limited to a photosensitive element, a circuit board, and a light-shielding element.

[0033] By integrating the tip 110 and the lens 121 into one, the endoscope module 100 can reduce the assembly difficulty of the endoscope module 100 and reduce the deformation of the endoscope module 100 during assembly, which is beneficial to improving the assembly efficiency and assembly accuracy of the endoscope module 100.

[0034] Please see Figure 2 In some embodiments, the tip 110 includes a molded body 111 and a mounting body 112. The molded body 111 is sleeved on the lens barrel 1211 and is integral with the lens barrel 1211. The mounting body 112 is connected to one end of the molded body 111 and has a detection through hole 110a. Along the direction from the molded body 111 to the mounting body 112, the molded body 111 and the mounting body 112 have a stepped structure.

[0035] Therefore, the stepped structure of the molded body 111 and the mounting body 112 is beneficial to improving the connection stability between the encapsulating adhesive 140 and the tip 110.

[0036] In some embodiments, the surface of the molded body 111 facing away from the lens barrel 1211 and the surface of the mounting body 112 facing away from the detection through hole 110a are both arc-shaped surfaces.

[0037] Therefore, by the above-mentioned arrangement, the connection strength between the encapsulating adhesive 140 and the molded body 111 and the mounting body 112 can be increased, and the connection stability between the encapsulating adhesive 140 and the tip 110 can be further improved.

[0038] Please see Figure 2 In some embodiments, the encapsulating adhesive 140 includes a first adhesive 141 and a second adhesive 142. The first adhesive 141 is connected to the surface of the molded body 111 facing away from the lens 121, the surface of the mounting body 112 facing away from the detection through hole 110a, and the circuit board unit 122, respectively. The second adhesive 142 is sleeved on the circuit board unit 122. The second adhesive 142 is connected to the surface of the molded body 111 facing the tail sleeve 130, the surface of the mounting body 112 facing the tail sleeve 130, the surface of the tail sleeve 130 facing the tip 110, the first adhesive 141, and the circuit board unit 122, respectively. The first adhesive 141 and the second adhesive 142 are integrally formed by a single injection molding process.

[0039] Therefore, through the above arrangement, the first adhesive 141 and the tip 110 are sleeved together, and the first adhesive 141 and the second adhesive 142 are arranged sequentially along the axial direction of the detection through hole 110a, which can improve the connection stability between the encapsulating adhesive 140 and the tip 110.

[0040] In some embodiments, along the axial direction of the detection through-hole 110a, the length of the first colloid 141 is greater than the length of the second colloid 142.

[0041] Therefore, through the above settings, the encapsulating adhesive 140 can achieve both fixing of the tip 110 and the tail sleeve 130 and miniaturization.

[0042] Please see Figure 2 In some embodiments, the surface of the second colloid 142 facing the tail sleeve 130 is provided with an extension 142a, and the surface of the tail sleeve 130 facing the second colloid 142 is provided with a retaining portion 130a, and the extension 142a and the retaining portion 130a are engaged in a slot.

[0043] In this embodiment, the extension 142a is a convex structure, and the retaining portion 130a is a recessed structure. In other embodiments, the extension 142a may also be a recessed structure, and the retaining portion 130a may be a convex structure.

[0044] Therefore, by using the slots of the extension 142a and the retaining part 130a, the connection accuracy and connection strength of the encapsulating adhesive 140 and the tail sleeve 130 can be improved.

[0045] Please see Figure 1 and Figure 2 In some embodiments, the endoscope module 100 further includes a snake tube 150. The snake tube 150 is connected to the end of the tail sleeve 130 away from the encapsulating adhesive 140 and is sleeved on the circuit board unit 122.

[0046] Therefore, the snake tube 150 can improve the ease of movement of the endoscope module 100 by manual or external components.

[0047] In some embodiments, the endoscope module 100 further includes an inlet 160. The inlet 160 is inserted into the tail sleeve 130 and the detection through hole 110a for the passage of the detection element.

[0048] Therefore, the guide member 160 can guide the detection member into the detection through hole 110a, thereby improving the efficiency of the detection member in conjunction with the endoscope module 100 for detection.

[0049] Please see Figure 3 In some embodiments, the endoscope module 100 further includes an illumination element 170. The illumination element 170 is connected to the end of the tip 110 opposite to the tail sleeve 130. In this embodiment, there are two illumination elements 170, located on opposite sides of the lens 121. Exemplarily, the illumination element 170 may be a phosphor-based LED.

[0050] Therefore, the illumination element 170 can provide illumination to the endoscope module 100 to improve the clarity of the images acquired by the endoscope module 100.

[0051] This application embodiment also provides a testing mechanism (not shown), including a testing element (not shown) and the above-mentioned endoscope module 100. When the testing mechanism is working, the testing element is inserted into the testing through hole 110a.

[0052] The endoscope module 100 in the above-mentioned testing mechanism integrates the tip 110 and the lens 121, which reduces the assembly difficulty of the endoscope module 100 and reduces the deformation of the endoscope module 100 during assembly, which is beneficial to improving the assembly efficiency and assembly accuracy of the testing mechanism.
