[0045] The adjustment mechanism for an industrial camera according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Reference Figures 1 to 3 As shown, the adjustment mechanism for an industrial camera provided in this embodiment of the present invention includes: a linear adjustment seat 10, an angle adjustment component 20, and a camera body 30. When operated, the linear adjustment seat 10 can move linearly along the height direction. The linear adjustment seat 10 includes: a fixed seat 11, a movable seat 12, and a first micro head 13. The fixed seat 11 is suitable for installation on a lens mount and can be fixed to the lens mount by bolts. The movable seat 12 is slidably disposed on the side of the fixed seat 11 in the width direction, and the camera body 30 is fixed on the movable seat 12, so that the movable seat 12 can drive the camera body 30 to slide relative to the fixed seat 11. The first micro head 13 is threadedly connected to the fixed seat 11 and extends to be rotatably connected to the movable seat 12. When adjusting the focus of the camera body 30, the first micro head 13 can be manually rotated to make the movable seat 12 drive the camera body 30 to move up and down relative to the fixed seat 11, thereby completing the focusing operation of the camera body 30.

[0047] Reference Figure 1As shown, a mounting block 111 is provided on the side of the fixed base 11 along its length. The first microhead 13 is threadedly connected to the mounting block 111. A connecting block 121 is provided on the movable base 12 and is located below the first microhead 13. The lower end of the first microhead 13 is rotatably connected to the connecting block 121. The first microhead 13 is threadedly connected to the mounting block 111, so that when the first microhead 13 is manually rotated, it can move along its own axial direction and drive the connecting block 121 to move up and down. This allows the movable base 12 to be adjusted in height along with the connecting block 121. Thus, the focus of the camera body 30 can be adjusted by using the first microhead 13. Once focusing is complete, the adjustment method is simpler. Optionally, the outer peripheral surface of the first micrometer head 13 can be marked with scale lines to make it easier to observe the adjustment distance. As a preferred method, a fixing plate 41 is provided on the side of the fixed base 11 away from the mounting block 111. The fixing plate 41 has an oblong hole 411. The locking member 40 passes through the oblong hole 411 and is connected to the moving base 12, so that the locking member 40 can move along the length direction of the oblong hole 411. After the focusing operation is completed, the fixing plate 41 and the moving base 12 can be locked and fixed by the locking member 40, so that there will be no offset between the moving base 12 and the fixed base 11, which improves the stability of the camera body 30 after adjustment.

[0048] Optionally, a cross rail 14 is provided between the fixed base 11 and the movable base 12. The cross rail 14 slidably connects the fixed base 11 and the movable base 12. The cross rail 14 can be an existing type, such as the LWR type cross rail 14 from Reschberg. By connecting the fixed base 11 and the movable base 12 through the cross rail 14, the overall structure is more compact than the traditional one, and the fixed base 11 and the movable base 12 occupy less space.

[0049] Furthermore, the angle adjustment component 20 is mounted on the linear adjustment base 10 and can move linearly with the linear adjustment base 10. The adjustment rod 21 of the angle adjustment component 20 protrudes out of the linear adjustment base 10 and can rotate around its own axial direction when operated. The camera body 30 is detachably inserted into the adjustment rod 21 so as to rotate with the adjustment rod 21 to adjust its own optical axis angle. When installing the camera body 30, it can be quickly inserted between the camera body 30 and the adjustment rod 21, which improves the installation efficiency of the camera body 30.

[0050] Reference Figure 3 and Figure 4As shown, the angle adjustment assembly 20 includes: a second micrometer head 22, a rotating rod 23, a first bevel gear 24, a second bevel gear 25, and a fastener 26. The movable base 12 has a receiving groove on the side near the fixed base 11, within which the first bevel gear 24 and the second bevel gear 25 can rotate. The second micrometer head 22 is rotatably mounted on the movable base 12. The first end of the rotating rod 23 is fixedly connected to the second micrometer head 22, and the second end extends into the receiving groove. The first bevel gear 24 is located at the second end of the rotating rod 23. By manually rotating the second micrometer head 22, the first bevel gear 24 can rotate with the rotating rod 23. The second bevel gear 25 is mounted on the adjustment rod 21 and meshes with the first bevel gear 24, allowing the adjustment rod 21 to achieve a transmission connection with the first bevel gear 24 through the second bevel gear 25. When the first bevel gear 24 rotates, the adjustment rod 21 engages with the first bevel gear 24. Figure 1 As shown, the second bevel gear 25 can drive the adjusting rod 21 to rotate, so that the optical axis of the camera body 30 can deflect with the rotation of the adjusting rod 21. When the optical axis of the camera is perpendicular to the object being measured, the optical axis angle adjustment of the camera is completed, avoiding optical axis angle deviation during focusing. It can be understood that the optical axis direction of the camera body 30 is parallel to its height direction. By adjusting the optical axis angle of the camera body 30 to be perpendicular to the object being measured, the image is ensured to be closest to the real scene, and the shape of the object is not significantly deviated. In this way, the angle adjustment of the camera body 30 can be completed. As a preferred method, the fastener 26 is threaded onto the moving base 12 and extends into the receiving groove. After the angle adjustment is completed, the fastener 26 is rotated with an Allen wrench so that it can abut against the circumference of the rotating rod 23 to restrict the rotation of the rotating rod 23. This restricts the rotation of the adjusting rod 21, and the camera body 30 is also restricted from rotation by the adjusting rod 21, ensuring that the optical axis angle of the camera body 30 remains unchanged when adjusting the focus of the camera body 30, making the adjustment operation simpler and more reliable.

[0051] Reference Figure 5 As shown, the adjusting rod 21 includes a connecting section 211, a rotating section 212, and a plug-in section 213. The connecting section 211 is connected to the second bevel gear 25. The rotating section 212 is rotatably mounted on the movable base 12, and one end of the rotating section 212 is connected to the connecting section 211. When the second bevel gear 25 is driven to rotate, the rotating section 212 rotates with the connecting section 211. The other end of the rotating section 212 is connected to the plug-in section 213, so that the plug-in section 213 can rotate together with the rotating section 212. When the plug-in section 213 is inserted into the plug-in hole 31 of the camera body 30, the plug-in section 213 and the plug-in hole 31 can be quickly plugged in, which makes the camera body 30 easier to test and install, and enables quick installation and testing.

[0052] Furthermore, the outer peripheral surface of the insertion segment 213 has an elastic locking block 214. The elastic locking block 214 protrudes radially from the surface of the insertion segment 213, with one end forming a gap with the insertion segment 213 and the other end connected to the insertion segment 213. This allows the elastic locking block 214 to generate a certain elastic force through its own rigidity. The insertion hole 31 of the camera body 30 can be located on the outer shell of the camera body. The insertion hole 31 corresponds to the insertion segment 213. When installing the camera body 30 and the insertion segment 213, the insertion segment 213 can be inserted into the insertion hole 31 to fix it within the insertion hole 31. By providing an insertion opening 311 on the inner peripheral surface of the insertion hole 31, the elastic locking block... When the elastic locking block 214 enters the insertion hole 31, it can be pushed against by the circumferential surface of the insertion hole 31 to overcome its own elasticity and approach the insertion section 213. When it enters the insertion port, it can be restored under its own elasticity and abut against the insertion port 311, so that the elastic locking block 214 can be engaged with the insertion port 311 in the circumferential direction to form an interlock. Then, when the adjusting rod 21 rotates, the elastic locking block 214 rotates with the adjusting rod 21 and can drive the camera body 30 to rotate. As a preferred embodiment, the elastic locking block 214 can be set with a concave-convex structure along its own length direction, so that the elastic locking block 214 can limit and clamp the camera body 30 in its length direction, ensuring that the camera body 30 is more stably engaged.

[0053] The adjustment mechanism for industrial cameras provided by this utility model can mount the camera body 30 on the adjustment rod 21, so that the angle of the camera body 30 can be adjusted by the angle adjustment component 20. After the optical axis angle of the camera body 30 is adjusted, the focus of the camera body 30 can be adjusted by the linear adjustment seat 10. The overall structure is simpler and the overall space occupied is reduced. By adjusting the angle before focusing, the angle change is avoided, making the adjustment operation simpler and improving efficiency.
