Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0019] To address the issue of existing technologies relying on manual methods using dial indicators, such as... Figure 1 The workpiece shown has shortcomings in terms of convex hull flatness and height detection. (Refer to...) Figure 2 and Figure 3 As shown, this application discloses a convex hull detection device, including a chain conveyor 10, a flatness and height detection mechanism 30, and a laser marking mechanism 40; The chain conveyor 10 is equipped with a support fixture 20 for loading workpieces above the chain plate; The flatness and height detection mechanism 30 includes a YZ axis drive unit 31 located outside the middle section of the chain conveyor 10 and a detection unit 32 connected to the YZ axis drive unit 31; The laser marking mechanism 40 includes a laser marking unit 41 mounted above the chain conveyor line at the rear end of the flatness and height detection mechanism 30.

[0020] In practice, the operator places each workpiece to be inspected sequentially on the carrying fixture 20 of the chain conveyor 10 at the loading and unloading position. When the workpiece reaches the inspection position, the YZ axis drive unit 31 drives the laser engraving unit 41 to push out along the Y axis, and then controls it to descend along the Z axis until its inspection part contacts the protrusion of the workstation for inspection. If the workpiece fails the inspection, when the chain conveyor 10 carries the workpiece to the laser engraving unit 41, the laser engraving unit 41 will automatically mark the surface of the workpiece with the character for "unqualified". After the above work is completed and the chain conveyor 10 carries it back to the loading and unloading position, the operator can sort and unload the workpiece and put it back into other workpieces to be inspected. By repeating this process, it is possible to inspect a large number of workpieces one by one.

[0021] To secure the workpiece and prevent it from falling during the conveyor belt 10, this application provides a contour groove 211 on the upper surface of the support fixture 20, which is identical in shape to the workpiece. Four permanent magnets 22 are embedded around the bottom wall of the contour groove 211. In actual use, the operator needs to place the workpiece to be inspected into the contour groove 211 and use the four permanent magnets 22 to attract and fix it. In addition, one side of the support fixture 20 is provided with a through groove 212 that communicates with the contour groove 211 for the insertion of a finger. After the convexity inspection of the workpiece is completed, the operator can insert his finger into the through groove 212 to remove the workpiece, which is more convenient to use.

[0022] In one specific embodiment, the YZ axis drive unit 31 of this application includes a frame 311 located outside the middle section of the chain conveyor 10, a Y-axis servo drive module 312 located above the platform of the frame 311, two linear guide rails 313 located on both sides of the Y-axis servo drive module 312 located above the platform of the frame 311, a slide table 314 slidably connected to the two linear guide rails 313 and connected to the Y-axis servo drive module 312, a support 315 fixedly located above the slide table 314, and a support 315 located on the support 314. 15. A Z-axis lead screw stepper motor 316 facing the side of the chain conveyor 10, and a lifting block 317 connected to the bottom of the lead screw of the Z-axis lead screw stepper motor 316; the detection unit 32 is installed at the bottom of the lifting block 317. When inspecting the workpiece, the Y-axis servo drive module 312 drives the slide table 314 to move along the Y-axis direction and extend to the set position. Then, the Z-axis lead screw stepper motor 316 drives the lifting block 317 to descend. When the detection unit 32 contacts the protrusion of the workpiece, it can detect its flatness and height.

[0023] In addition, the bottom of the lifting block 317 is provided with anti-collision rubber 33 that contacts the bearing fixture 20. In actual use, the detection unit 32 can buffer when it comes into contact with the protrusion of the workpiece, avoiding rigid contact with the protrusion. In this way, the detection unit 32 will not be easily damaged, increasing its service life. Specifically, the detection unit 32 of this application is a detection sensor, and the Keyence GT2-H12K sensor can be selected in actual use.

[0024] In one specific implementation, the laser engraving unit 41 includes a truss 411 mounted above the chain conveyor line at the rear end of the flatness and height detection mechanism 30, and a laser engraving head 412 located at the bottom of the truss 411. When marking the workpiece for non-conformity, the laser engraving head 412 will automatically mark the corresponding workpiece surface with a non-conformity mark. The mark can be a font or a symbol. In specific implementation, it can be designed by those skilled in the art, and will not be elaborated on here.

[0025] In one specific implementation, a blocking mechanism 50 is provided below the middle section of the chain conveyor 10. The blocking mechanism 50 includes a [shaped member 51] located below the interior of the chain conveyor 10, a cylinder 52 located inside the [shaped member 51], and a baffle 53 located above the [shaped member 51 and connected to the cylinder 52. Before one chain plate of the chain conveyor 10 is about to reach the flatness and height detection mechanism 30, the cylinder 52 will push the baffle 53 to extend. In this way, the chain plate of the chain conveyor 10 can be blocked when it moves. At this time, the flatness and height detection mechanism 30 can accurately detect the flatness and height of the corresponding workpiece. Moreover, when the baffle 53 blocks one chain plate of the chain conveyor, the corresponding chain plate behind it will correspond to the laser marking mechanism 40. In this way, the laser marking mechanism 40 laser marks the unqualified workpiece.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
