Description

Technical Field

[0001] This utility model relates to the field of industrial visual inspection technology, specifically to an industrial camera system. Background Technology

[0002] In industrial vision systems, the compatibility between the industrial camera system and the lens directly determines the image quality and detection accuracy. Therefore, during the production and selection of industrial camera systems and lenses, various combination matching tests are required to evaluate key optical performance such as resolution, distortion, depth of field, and image plane consistency. Currently, in the process of matching lenses with cameras, the selected lens needs to be manually screwed into the corresponding interface of the industrial camera system and tested. When testing the same lens with a camera of a different model or batch, the operator needs to manually unscrew it and then install it onto the interface of the next camera under test and screw it in again for testing.

[0003] Therefore, during repeated disassembly and assembly, since the camera's threaded interface usually uses metal threads, repeated disassembly and assembly operations will cause wear on the threaded interface, affecting the assembly accuracy and quality of the lens. In addition, the operation is also more cumbersome during the testing process, reducing the efficiency of matching tests between the lens and the camera. Utility Model Content

The connecting ring is fixed to the lens by a connector, and one end of the connector passes through the connecting ring and is threaded to the threaded hole, while the other end can be inserted into the mounting hole. When the connector is inserted into the mounting hole, it is locked and fixed by the locking assembly, so that the lens is connected and fixed to the mounting base.

[0005] Preferably, the locking assembly includes: A locking element, which is slidably disposed within the mounting base, with one end of the locking element extending out of the mounting hole; An elastic element is connected to the other end of the locking element and is used to elastically push the locking element out into the mounting hole.

[0006] Preferably, the locking element includes: The curved end faces into the mounting hole; The connecting end is opposite to the arc-shaped end and is connected to the elastic element.

[0008] Preferably, the locking section has an annular groove on its circumferential surface, the annular groove being recessed along the radial direction of the locking section, the annular groove being used for the locking member to elastically abut against, thereby restricting the movement of the plug-in member.

[0009] Preferably, the edge of the annular groove is formed with a transition arc surface, which forms a transition connection between the annular groove and the circumferential surface of the locking section. Preferably, the end of the locking section is provided with a tightening groove, which extends in the radial direction of the locking section.

[0010] Preferably, the connecting ring has an insert, the threaded portion of the lens extends into the insert, and the diameter of the threaded portion is smaller than the diameter of the insert.

[0023] The industrial camera system of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the industrial camera system provided in this embodiment of the present invention includes: a camera body 10, a mounting base 20, a locking assembly 30, and a lens 40. The mounting base 20 is fixed on the camera body 10 and has a mounting hole 21. The locking assembly 30 is disposed in the mounting base 20 and elastically protrudes from the mounting hole 21. The end cap of the lens 40 has a pre-set threaded hole 402. The lens 40 is detachably provided with a connecting ring 41, and the connecting ring 41 is fixed to the lens 40 by a connector 42. One end of the connector 42 passes through the connecting ring 41 and is threadedly connected to the threaded hole 402, and the other end can be inserted into the mounting hole 21. When the connector 42 is inserted into the mounting hole 21, the connector 42 is radially locked by the locking assembly 30 so that the lens 40 is connected and fixed to the mounting base 20.

[0025] like Figure 3As shown, the connecting ring 41 has an insertion port 411. The threaded portion 401 of the lens 40 extends into the insertion port 411, and the diameter of the threaded portion 401 is smaller than the diameter of the insertion port 411. When the lens 40 is fixed to the mounting base 20, the connecting ring 41 can fit against the mounting base 20. Furthermore, since the mounting base 20 has an annular wall 22 protruding from the camera body 10, and the outer diameter of the annular wall 22 is equal to the diameter of the insertion port 411, the annular wall 22 can precisely engage with the insertion port 411, ensuring a higher degree of fit. Simultaneously, the annular wall 22... The inner diameter of the annular wall 22 is larger than the diameter of the threaded portion 401, allowing the threaded portion 401 to extend into the annular wall 22. The optical interface 221 within the annular wall 22 is aligned with the threaded portion 401. The optical interface 221 corresponds to the insertion port 411. When the lens 40 is fixed to the mounting base 20, the annular wall 22 is inserted into the insertion port 411, and the threaded portion 401 extends into the optical interface 221. This ensures that the optical axis center of the lens 40 is aligned with the image sensor of the camera body 10, guaranteeing accurate focusing between the lens 40 and the camera body 10 after installation.

[0026] Furthermore, in combination Figure 4 As shown, the mounting base 20 has a mounting portion 23 that surrounds the outer periphery of the annular wall 22 and is connected to the annular wall 22, and a mounting hole 21 is provided on the mounting portion 23, so that when the connecting ring 41 is attached to the mounting portion 23, the plug-in member 42 can be accurately aligned with the mounting hole 21 for insertion, making the insertion operation simpler.

[0027] like Figure 2 and Figure 5 As shown, the connector 42 includes a threaded section 421, a locking section 422, and a stop 423. The threaded section 421 is used for threaded connection with the camera body 10. The stop 423 is located between the threaded section 421 and the locking section 422 and protrudes radially. When it is necessary to perform matching tests between the same lens 40 and different cameras, a connecting ring 41 can be installed on the lens 40. When installing the connecting ring 41, the threaded section 421 can pass through the through hole 412 on the connecting ring 41 and be threadedly connected with the threaded hole 402 on the lens 40. A slotted screw can be used for the threaded connection. A screwdriver is inserted into the tightening groove 4223 at the end of the locking section 422, so that the screwdriver can be rotated in the tightening groove 4223 to tighten and fix the connector 42 and the lens 40. The stop part 423 can also restrict the connecting ring 41 to the lens 40, ensuring a more stable fixation between the lens 40 and the connecting ring 41. Optionally, the connecting ring 41 can be provided with an embedding groove 413 surrounding the through hole 412. The embedding groove 413 is used for the stop part 423 to be embedded to prevent the stop part 423 from protruding from the surface of the connecting ring 41, ensuring that the connecting ring 41 can fit tightly on the mounting base 20.

[0028] Combination Figure 2 and Figure 5 As shown, the locking assembly 30 includes a locking member 31 and an elastic member 32. The locking member 31 is slidably disposed in the mounting base 20 through a sliding hole 231, and one end of the locking member 31 extends into the mounting hole 21. The elastic member 32 is connected to the other end of the locking member 31 and is used to elastically push the locking member 31 out into the mounting hole 21. The locking section 422 of the connector 42 is integrally connected with the threaded section 421. When installing the lens 40, the connector 42 can be aligned with the mounting hole 21 so that the locking section 422 of the connector 42 can extend. When the locking section 422 is inserted into the mounting hole 21, the annular groove 4221 on the circumferential surface of the locking section 422 is recessed along the radial direction of the locking section 422. This allows the arc-shaped end 311 of the locking member 31 to abut against the annular groove 4221 under the elastic force of the elastic member 32. It can be understood that since the upper and lower edges of the annular groove 4221 both have transition arc surfaces 4222, these transition arc surfaces 4222 form a transition connection between the annular groove 4221 and the circumferential surface of the locking section 422. When the locking section 422 is inserted into the mounting hole 21... When inserted, the end of the locking section 422 can push against the transition arc surface 4222, allowing the locking member 31 to overcome the elastic force of the elastic member 32 and move towards the elastic member 32 into the sliding hole 231. The arc end 311 of the locking member 31 continuously abuts against the circumferential surface of the locking section 422, moving relative to it. After the locking section 422 continues to be inserted downwards, when the annular groove 4221 aligns with the arc end 311 of the locking member 31, the locking member 31 is ejected from the sliding hole 231 under elastic force and abuts against the annular groove 4221, so that the locking member 31 inserts the connector 4. 2. Locking and fixing: When it is necessary to disassemble the lens 40, since the upper and lower edges of the annular groove 4221 are both formed with transition arc surfaces 4222, when the lens 40 is pulled, the locking section 422 can push against the locking member 31 so that the locking member 31 can overcome the elastic force of the elastic member 32 and retract into the sliding hole 231. When the locking section 422 disengages from the locking member 31, the disassembly of the lens 40 is completed, making the installation and disassembly of the lens 40 during the testing process simpler, and it will not contact the threaded part 401 of the lens 40, thus avoiding wear on the threaded part 401 of the lens 40.

[0029] As a preferred embodiment, the locking member 31 has a connecting end 312 that is opposite to the arc end 311 and connected to the elastic member 32. Both the top and bottom surfaces of the locking member 31 are provided with a pushing arc surface 313. The diameter of the locking section 422 can be slightly smaller than the diameter of the arc end 311. When the locking section 422 is inserted into or pulled out of the mounting hole 21, the locking section 422 can first abut against the pushing arc surface 313 and generate a pushing force on the locking member 31, so that the locking section 422 is embedded in the arc end 311 and pushes the locking member 31 back into the sliding hole 231. Optionally, the length of the locking member 31 extending out of the mounting hole 21 should be less than the radius of the mounting hole 21, so as to avoid the top of the locking member 31 blocking the locking section 422 when the locking section 422 is inserted into the mounting hole 21, and ensure that the locking section 422 can be accurately inserted into the mounting hole 21 and elastically locked by the locking member 31.

[0030] The industrial camera system provided by this utility model allows for the following process during the matching test between the lens 40 and the camera body 10: the connecting ring 41 can be fixed to the lens 40 via the connector 42, and pressure can be manually applied to the lens 40 and the connector 42 can be inserted into the mounting hole 21 so that the locking component 30 can radially lock the connector 42, enabling the lens 40 to be quickly installed and fixed to the camera body 10. After the test is completed, the lens 40 can be pulled again to separate the connector 42 and the locking component 30, allowing the lens 40 to be installed on other cameras for further testing. This avoids wear caused by repeated disassembly and assembly operations, ensures that the assembly accuracy and quality of the lens 40 are not affected during the test, and simplifies the testing operation, thus improving the efficiency of the matching test between the lens 40 and the camera.
