Description

Technical Field

[0001] This invention belongs to the technical field of inspection machine accessories, and particularly relates to a visual inspection camera adjustment device and its adjustment method. Background Technology

[0002] In machine vision inspection equipment, the position of the vision inspection camera directly determines the image acquisition accuracy. Therefore, it is generally equipped with a camera adjustment device to adjust the relative distance between the camera and the workpiece to be inspected, so as to adapt to the imaging focal length requirements of workpieces of different specifications.

[0003] Existing camera adjustment devices mostly adopt a gear and rack transmission structure. By rotating the adjustment knob, the gear is driven to rotate, and the gear and rack mesh to drive the slide block to move along the slide rail to complete the adjustment of the camera's optical path position. However, this adjustment method, which relies on the rotation of the knob, is cumbersome and inconvenient when making long-stroke position adjustments. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a visual inspection camera adjustment device and method, thereby improving the convenience of camera position adjustment.

[0005] In view of this, the present invention provides a visual inspection camera adjustment device for mounting a visual inspection camera inside an inspection machine, wherein the inspection machine includes a frame and an inspection chamber, and the adjustment device includes: The slide rail is installed in the detection chamber via connecting parts at both ends; A slide block, mounted above a slide rail, is equipped with a vision inspection camera; A rack is mounted on a slide rail, and the slide block has a groove that matches the rack. An adjusting gear is rotatably mounted in a slide block, and extends radially to a groove to mesh with a rack. A first knob is provided on the axial side to drive the rotation of the adjusting gear. The lifting mechanism, connected to the slide, is used to drive the slide to lift and lower to switch the adjustment mode; A sliding mechanism, slidably connected to a slide rail, is used for the sliding connection of the lifting mechanism along the slide rail; The adjustment modes include coarse adjustment mode, fine adjustment mode, and locking mode.

[0006] In the above technical solution, further: In coarse adjustment mode, the lifting mechanism raises the slide block, disengaging the adjusting gear from the rack. In the fine-tuning mode, the lifting mechanism lowers the slide, causing the adjusting gear to mesh with the rack; The locking mode involves the lifting mechanism lowering the slide block to press the adjusting gear against the rack.

[0007] In the above technical solution, further: The slide has a countersunk hole along the direction of the vertical extension of the rack, and the countersunk hole penetrates the inner wall of the groove; The adjusting gear has an axial shaft that extends into a countersunk hole and connects to the first knob. The shaft is located on both sides of the countersunk hole and is connected to the bearing on the inner wall of the countersunk hole.

[0008] In the above technical solution, the sliding mechanism further includes: The upper support plate is installed above the slide rail and is equipped with a first set of rollers that are slidably connected to the upper end face of the slide rail. The lower support plate is installed below the slide rail and is equipped with a second set of rollers that are slidably connected to the lower end face of the slide rail. The first connecting plate is connected to the upper support plate at one end and to the lower support plate at the other end.

[0009] In the above technical solution, further: Both the upper support plate and the lower support plate are provided with a first protrusion and a second protrusion on the side near the slide rail. The first roller group and the second roller group each include multiple rollers and shafts, and the two ends of the shafts are rotatably connected to the first protrusion and the second protrusion, respectively.

[0010] In the above technical solution, the lifting mechanism further includes: The second connecting plate is connected to the side of the slide; The lead screw includes a connecting section, a first threaded section, and a limiting end. The connecting section is rotatably connected to both the upper and lower support plates, while the limiting end is located on the side of the first threaded section away from the connecting section. The lead screw nut is connected to the second connecting plate and is threadedly engaged with the first threaded section of the lead screw. The maximum axial travel of the lead screw nut is greater than the radial engagement depth between the adjusting gear and the rack. The drive assembly is installed below the slide rail; Multiple lead screws are symmetrically arranged along the adjustment direction of the slide block, and the drive assembly is used for the synchronous rotation of multiple lead screws in the same direction.

[0011] In the above technical solution, the driving component further includes: The housing is connected to the lower support plate; The driven gear is installed at the end of the lead screw connection section away from the first thread section and is located inside the housing; The driving gear is installed inside the housing and meshes with the driven gear. The drive shaft is rotatably connected to the housing, with one end connected to the drive gear and the other end extending out of the housing and equipped with a second knob.

[0012] In the above technical solution, further: The drive shaft includes a second threaded section located outside the housing, and the second threaded section is connected to an adjusting nut; The axial length of the second threaded section is greater than the axial length of the adjusting nut.

[0013] In the above technical solution, further: The housing has two latching parts, which are engaged with the lower support plate. Notches are provided at the corresponding snap-fit ​​parts of the first connecting plate and the housing.

[0014] This invention provides an adjustment method for a visual inspection camera adjustment device, comprising the following steps: S1: Hold the second knob and loosen the adjusting nut using the wrench; S2: Rotate the second knob to drive the drive shaft and the drive gear to rotate, which in turn drives the driven gear and the lead screw to rotate. When the lead screw rotates, the lead screw nut drives the slide to rise through the second connecting plate and separates the adjusting gear from the rack. S3: Slide the handheld slide along the slide rail to make coarse adjustments to the position of the slide and the visual inspection camera on the slide; S4: After the coarse adjustment is completed, rotate the second knob in the opposite direction to drive the slide to descend and make the adjusting gear mesh with the rack; S5: Turn the first knob to adjust the position of the slide and the visual inspection camera on the slide by adjusting the gear along the rack and sliding the slide along the slide rail; S6: After fine-tuning, keep rotating the second knob in the opposite direction to drive the slide to continue descending and press the adjusting gear against the rack. S7: Hold the second knob and tighten the adjusting nut with a wrench to lock the slide and the vision inspection camera on the slide.

[0015] The beneficial effects of this invention are as follows: 1. By setting three switchable adjustment modes—coarse adjustment, fine adjustment, and locking—the system can switch to coarse adjustment mode in the early stages of adjustment to greatly improve the efficiency of position adjustment; switch to fine adjustment mode in the middle and later stages of adjustment to ensure the accuracy of camera positioning adjustment; and switch to locking mode after the position adjustment is completed to fix the slide position and ensure that the camera position remains stable during the equipment testing process.

[0016] 2. The device is equipped with an upper and lower opposing roller sliding mechanism and a symmetrical synchronous screw lifting structure. The sliding translation and slide lifting process is uniform in force and runs smoothly. The gear and rack meshing is precise, which can not only ensure the positioning accuracy during the fine adjustment stage, but also avoid lifting jamming and tooth surface squeezing damage to parts.

[0017] 3. After fine adjustment, the slide can be pressed down to tighten the gear rack, and the adjusting nut at the end of the drive shaft will be used for friction locking to form a double locking and limiting structure. During long-term inspection operations, the camera position is not easily shifted, effectively ensuring the continuous imaging and inspection accuracy of machine vision. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] Example 1:

[0021] This embodiment provides a visual inspection camera 4 adjustment device for mounting the visual inspection camera 4 inside an inspection machine, wherein the inspection machine includes a frame 100 and an inspection chamber 200, and the adjustment device includes: The slide rail 1 is installed in the detection chamber 200 through connecting parts 2 at both ends; The slide block 3 is mounted above the slide rail 1 and is equipped with a vision inspection camera 4; The rack 5 is mounted on the slide rail 1, and the slide block 3 has a groove 6 that matches the rack 5; The adjusting gear 7 is rotatably mounted in the slide block 3, and extends radially to the groove 6 to mesh with the rack 5. A first knob 10 is provided on the axial side to drive the rotation of the adjusting gear 7. The lifting mechanism 8 is connected to the slide 3 and is used to drive the slide 3 to lift and lower to switch the adjustment mode; The sliding mechanism 9 is slidably connected to the slide rail 1 and is used for the sliding connection of the lifting mechanism 8 along the slide rail 1. The adjustment modes include coarse adjustment mode, fine adjustment mode, and locking mode; The specific structure of the visual inspection camera 4 is existing technology and can be directly known by those skilled in the art from the camera structure in conventional inspection equipment; at the same time, the difference in the camera's own structure will not affect the working process of the adjustment device of this application, so it will not be described in detail here.

[0022] As can be seen from this embodiment, the stability of the slide block 3 during translation is improved by using the sliding mechanism 9; the slide block 3 and the sliding mechanism 9 are connected by the lifting mechanism 8, and different adjustment modes can be switched by adjusting the height of the slide block 3; in the early stage of adjustment, the coarse adjustment mode can be switched to greatly improve the operation efficiency of position adjustment; in the middle and later stages of adjustment, the fine adjustment mode is switched to ensure the accuracy of camera positioning adjustment; after the position adjustment is completed, the locking mode is switched to fix the position of the slide block 3 to ensure that the camera position remains stable during the equipment detection process.

[0023] Example 2:

[0024] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: In the coarse adjustment mode, the lifting mechanism 8 raises the slide block 3, causing the adjusting gear 7 to disengage from the rack 5; In the fine-tuning mode, the lifting mechanism 8 lowers the slide block 3, causing the adjusting gear 7 to mesh with the rack 5; The locking mode is that the lifting mechanism 8 lowers the slide 3, so that the adjusting gear 7 and the rack 5 are pressed together.

[0025] As can be seen in this embodiment, when the slide block 3 is lifted by the lifting mechanism 8, the adjusting gear 7 and the rack 5 disengage and disengage, allowing the slide block 3 to be manually pushed directly to achieve long-stroke adjustment and improve the efficiency of the initial position adjustment. The lifting mechanism 8 drives the slide block 3 to move down, so that the adjusting gear 7 and the rack 5 re-engage. Then, rotating the first knob 10 can drive the adjusting gear 7 to engage and drive the slide block 3 to move slightly along the slide rail 1, ensuring the positioning accuracy in the later fine-tuning stage. After the adjustment is in place, the lifting mechanism 8 further presses down on the slide block 3, so that the adjusting gear 7 and the rack 5 are tightly pressed together, thereby locking and fixing the position of the slide block 3.

[0026] Example 3:

[0027] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The slide block 3 has a countersunk hole 11 extending in the direction perpendicular to the rack 5, and the countersunk hole 11 penetrates the inner wall of the groove 6. The adjusting gear 7 is provided with a rotating shaft 12 in the axial direction, and extends out to a countersunk hole 11 to connect with the first knob 10. The rotating shaft 12 is located on both sides of the countersunk hole 11 in the axial direction and is connected to the bearing on the inner wall of the countersunk hole 11.

[0028] As can be seen from this embodiment, the slide block 3 has a countersunk hole 11 inside for mounting the adjusting gear 7. The rotating shaft 12 can radially limit the adjusting gear 7. The axial sides of the rotating shaft 12 inside the countersunk hole 11 are connected to the inner wall bearings of the countersunk hole 11, which can ensure the axial limit of the adjusting gear 7. This ensures that the adjusting gear 7 can accurately mesh or disengage from the rack 5 during the lifting and lowering of the slide block 3. The rotating shaft 12 is rotatably connected to the inner wall of the countersunk hole 11 through the bearings, which can stably support the rotating shaft 12 and ensure the smooth rotation of the rotating shaft 12. A groove 6 is provided at the countersunk hole 11 so that the adjusting gear 7 can be accommodated inside the groove 6 and mesh with the rack 5, ensuring the feasibility of the overall structure assembly and transmission.

[0029] Example 4:

[0030] This embodiment provides an adjustment device for a visual inspection camera 4. In addition to the technical solutions of the above embodiments, it also has the following technical features: the sliding mechanism 9 includes: The upper support plate 90 is installed above the slide rail 1 and is provided with a first roller group 91 that is slidably connected to the upper end face of the slide rail 1; The lower support plate 92 is installed below the slide rail 1 and is provided with a second roller group 93 that is slidably connected to the lower end face of the slide rail 1; The first connecting plate 94 is connected at one end to the upper support plate 90 and at the other end to the lower support plate 92.

[0031] As can be seen from this embodiment, by setting an upper support plate 90 above the slide rail 1 and a lower support plate 92 below the slide rail 1, the vertical positional offset between the sliding mechanism 9 and the slide rail 1 can be limited, ensuring the installation stability of the sliding mechanism 9 on the slide rail 1; at the same time, the upper support plate 90 and the lower support plate 92 can provide force support points for the lifting mechanism 8, so that when the lifting mechanism 8 drives the slide block 3 to perform lifting and lowering movements, the slide block 3 only produces vertical displacement relative to the slide rail 1, and will not interfere with the sliding connection relationship between the slide block 3 and the slide rail 1.

[0032] Example 5:

[0033] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The upper support plate 90 and the lower support plate 92 are each provided with a first protrusion 95 and a second protrusion 96 on the side near the slide rail 1. The first roller group 91 and the second roller group 93 each include multiple rollers and shafts, and the two ends of the shafts are rotatably connected to the first protrusion 95 and the second protrusion 96 respectively.

[0034] As can be seen from this embodiment, by relying on the first protrusion 95 and the second protrusion 96 to complete the assembly and positioning of the roller group, multiple sets of rollers cooperate with the slide rail 1 to form a rolling fit, which can not only provide multi-point support for the sliding mechanism 9 and effectively improve the stability of the slide block 3 during translation, but also reduce the sliding friction resistance when the slide block 3 moves relative to the slide rail 1.

[0035] Example 6:

[0036] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the lifting mechanism 8 includes: The second connecting plate 80 is connected to the side of the slide block 3; The lead screw 81 includes a connecting section 810, a first threaded section 811, and a limiting end 812. The connecting section 810 is rotatably connected to both the upper support plate 90 and the lower support plate 92, while the limiting end 812 is located on the side of the first threaded section 811 away from the connecting section 810. The lead screw nut 82 is connected to the second connecting plate 80 and is threadedly engaged with the first threaded section 811 of the lead screw 81. The maximum axial movement stroke of the lead screw nut 82 along the lead screw 81 is greater than the radial engagement depth between the adjusting gear 7 and the rack 5. The drive assembly is installed below slide rail 1; Multiple lead screws 81 are symmetrically arranged along the adjustment direction of the slide block 3, and the drive assembly is used for multiple lead screws 81 to rotate synchronously in the same direction.

[0037] As can be seen from this embodiment, the second connecting plate 80 realizes the fixed connection between the slide block 3 and the lead screw nut 82; the lead screw 81 is divided into a connecting section 810, a first threaded section 811 and a limiting end 812. The connecting section 810 can be rotated with the upper support plate 90 and the lower support plate 92. When the drive assembly drives the lead screw 81 to rotate, the first threaded section 811 of the lead screw 81 can drive the lead screw nut 82 to move up and down, thereby realizing the overall lifting and lowering of the slide block 3; the multiple lead screws 81 are symmetrically arranged along the translational adjustment direction of the slide block 3, which can make the support force of the lead screw 81 on the slide block 3 more uniform, and further improve the running stability of the slide block 3 during the lifting and lowering process; Furthermore, the connecting section 810 of the lead screw 81 is rotatably connected to the upper support plate 90 and the lower support plate 92. By supporting and limiting the lead screw 81 at two axial points, the axial assembly accuracy of the lead screw 81 itself can be guaranteed, and the overall stability of the lead screw 81 when supporting the slide block 3 via the lead screw nut 82 can also be improved. The lead screw 81 is provided with a limit end 812, which can prevent the lead screw nut 82 from coming off the lead screw 81, and at the same time can limit the maximum lifting height of the slide block 3.

[0038] Example 7:

[0039] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes: The housing 83 is connected to the lower support plate 92; Driven gear 84 is installed at the end of the connecting section 810 of lead screw 81 away from the first threaded section 811 and is located inside housing 83; The driving gear 85 is installed inside the housing 83 and meshes with the driven gear 84; The drive shaft 86 is rotatably connected to the housing 83, with one end connected to the drive gear 85 and the other end extending out of the housing 83 and equipped with a second knob 87.

[0040] As can be seen in this embodiment, rotating the second knob 87 drives the drive shaft 86 to rotate the drive gear 85. The drive gear 85 synchronously drives multiple sets of driven gears 84 to rotate in the same direction, so that each lead screw nut 82 rises and falls synchronously on the lead screw 81, effectively preventing jamming during the lifting process and ensuring smooth and stable lifting of the slide block 3. The housing 83 can protect the internal transmission components. This solution uses a manual method to drive the lifting of the slide block 3. On the one hand, it is convenient for operators to make adaptive adjustments and prevent over-adjustment. On the other hand, during the sliding block 3's descent, the operator can coordinate the operation of the first knob 10 and the second knob 87 to ensure that the adjusting gear 7 and the rack 5 are precisely aligned and meshed, avoiding hard squeezing caused by misalignment of the teeth and preventing damage to the equipment components.

[0041] Example 8:

[0042] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The drive shaft 86 includes a second threaded section 88 located outside the housing 83, and the second threaded section 88 is connected to an adjusting nut 89; The axial length of the second threaded section 88 is greater than the axial length of the adjusting nut 89.

[0043] As can be seen in this embodiment, a second threaded section 88 is provided on the outer side of the drive shaft 86, and a matching adjusting nut 89 is rotated along the second threaded section 88 to lock and unlock the drive shaft 86 in rotational state. Specifically, the adjusting nut 89 is screwed so that its end face is pressed against the surface of the housing 83, and the static friction formed by the contact surface between the two constrains the rotation of the drive shaft 86, preventing the slide 3 from being accidentally released from the locked state and ensuring the stability of the overall structure. The adjusting nut 89 is screwed in the opposite direction so that it is released from the surface of the housing 83, thereby eliminating the contact constraint and releasing the rotation limit of the drive shaft 86. At this time, operating the second knob 87 can drive the internal transmission components to operate and complete the lifting and lowering adjustment of the slide 3.

[0044] Example 9:

[0045] This embodiment provides a visual inspection camera 4 adjustment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The housing 83 is provided with two latching parts 830, and the two latching parts 830 are engaged with the lower support plate 92; In particular, notches 831 are provided at the corresponding buckle parts 830 of the first connecting plate 94 and the housing 83.

[0046] As can be seen from this embodiment, the housing 83 is assembled and connected to the lower support plate 92 through two latching parts 830, so as to reliably fix the housing 83; the first connecting plate 94 and the housing 83 are provided with avoidance notches 831 at the positions of the corresponding latching parts 830, so as to facilitate the operator to quickly unlock the latches and improve the convenience of disassembly and assembly of the housing 83.

[0047] Example 10:

[0048] This embodiment provides an adjustment method for the adjustment device of a visual inspection camera 4, including the following steps: S1: Hold the second knob 87 and loosen the adjusting nut 89 using a wrench; S2: Rotate the second knob 87 to drive the drive shaft 86 and the drive gear 85 to rotate, which in turn drives the driven gear 84 and the lead screw 81 to rotate. When the lead screw 81 rotates, the lead screw nut 82 drives the slide block 3 to rise through the second connecting plate 80, and causes the adjusting gear 7 to separate from the rack 5. S3: Slide the handheld slide 3 along the slide rail 1 to coarsely adjust the position of the slide 3 and the visual inspection camera 4 on the slide 3; S4: After the coarse adjustment is completed, the slide block 3 is driven to descend by rotating the second knob 87 in the opposite direction, and the adjusting gear 7 is engaged with the rack 5; S5: Rotate the first knob 10 to adjust the gear 7 along the rack 5 and make the slide 3 slide along the slide rail 1 to fine-tune the position of the slide 3 and the visual inspection camera 4 on the slide 3. S6: After fine-tuning, keep rotating the second knob 87 in the opposite direction to drive the slide block 3 to continue to descend, and make the adjusting gear 7 press against the rack 5; S7: Hold the second knob 87 and tighten the adjusting nut 89 with a wrench to lock the slide 3 and the visual inspection camera 4 on the slide 3.

[0049] As can be seen from this embodiment, the three-step adjustment process of coarse adjustment, fine adjustment, and locking is clearly divided. First, the slide block 3 is raised to disengage from the gear and rack 5, allowing for direct manual movement of the slide block 3 to achieve rapid coarse adjustment over a long stroke, significantly reducing the time required for large-scale position adjustments. After coarse adjustment, the slide block 3 is lowered to engage the gear and rack 5, and the gear and rack 5 is driven by a knob to achieve small-scale precise fine adjustment, effectively improving the camera's positioning accuracy. After fine adjustment, the slide block 3 is further pressed down to tightly engage the gear and rack 5, and the drive shaft 86 is locked with the adjusting nut 89. This double constraint firmly fixes the position of the slide block 3, preventing displacement during equipment testing. The entire process uses manual coordinated adjustment with two knobs. During the slide block 3's retraction and engagement phase, the gear angle can be finely adjusted simultaneously with the knobs to prevent tooth misalignment and hard compression that could damage parts. At the same time, the friction locking structure between the adjusting nut 89 and the housing 83 ensures simple and reliable operation, maintaining the locked state without the need for additional locking tools, thus balancing ease of operation, adjustment accuracy, and long-term operational stability.

This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
