Description

Technical Field

[0001] The present invention relates to the technical field of cutting error-proofing equipment, and in particular to an automatic error-proofing device based on cutting edge adaptation. Background Art

[0002] Traditional error-proofing devices rely on sensors or optical systems, resulting in complex structures and high costs. Manual inspection of cut workpieces (such as waterproof membranes and sealing panels), especially those with central cutouts, is inefficient and prone to misjudgments and omissions. Mechanical error-proofing devices typically require complex positioning mechanisms or additional power sources. Inspection using positioning jigs is difficult to meet the inspection requirements for a wide range of cut workpieces due to the varying positions and number of cutouts on each workpiece.

[0003] Therefore, an automatic error-proofing device based on cutting edge adaptation is needed to solve the above technical problems. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provides an automatic error-proofing device based on cutting edge adaptation.

[0007] Preferably, in the above-mentioned automatic error-proofing device based on cutting edge adaptation, at least three sliding cavities are provided through the base, the interior of the sliding cavity is slidably connected to a slider, and the bottom of each slider is equipped with a universal ball wheel.

[0008] Preferably, the above-mentioned automatic error-proofing device based on cutting edge adaptation, wherein the internal sliding connection of the slider is connected to an insertion rod, the lower end of the insertion rod is installed with an anti-slip pad, the anti-slip pad is located on the upper side of the universal ball wheel, a first spring is connected between the slider and the top of the inner wall of the sliding cavity, and a second spring is connected between the slider and the top of the insertion rod.

[0009] Preferably, the above-mentioned automatic error-proofing device based on cutting edge adaptation, wherein a locking assembly is provided on one side of the sliding cavity, the locking assembly includes an electric telescopic rod, the end of the telescopic rod of the electric telescopic rod is installed with a top block, and the side of the slider close to the top block is provided with a slope, and the slope is adapted to the bottom slope of the top block.

[0010] Preferably, in the above-mentioned automatic error-proofing device based on cutting edge adaptation, a wedge block is fixed on one side of the insertion rod close to the top block, the top inclined surface of the top block is adapted to the wedge block, and the wedge block is located on the upper side of the slider.

[0014] The present invention has the following beneficial effects: The error-proofing module inspects the workpiece. If the workpiece passes the inspection, the limit post can pass through the workpiece's cutting hole, and the edge is aligned with the limit post. If the workpiece fails the inspection, such as if the cut size is insufficient or out of tolerance (e.g., too short, with burred edges, or cut obliquely), the limit post cannot pass through the workpiece's cutting hole or may interfere with the limit post. The physical fit between the workpiece and the limit post directly determines whether the cutting edge has been properly cut. Relying solely on mechanical structure for inspection, the operator only needs to attempt to insert the workpiece to obtain the result. Furthermore, the position can be recalibrated when inspecting different workpiece models, eliminating the need for replacing the inspection device, thus saving equipment costs.

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] like Figures 1 to 8 As shown, an automatic error-proofing device based on cutting edge adaptation includes a base plate 1 and multiple error-proofing modules 3. The error-proofing modules 3 include a base 31 and a limiting column 32. A magnet is fixed to the bottom of the base 31, and the magnet is flush with the bottom surface of the base 31. The limiting column 32 is vertically fixed to the top of the base 31, and the base 31 is placed on the base plate 1. The cross-sectional shape of the limiting column 32 is consistent with the shape and size of the cutting hole 6 of the workpiece. The limiting column 32 is used to detect whether the position and size of the cutting hole 6 after the workpiece is cut are qualified. If qualified, the limiting column 32 can pass through the cutting hole 6 of the workpiece, and the edge is aligned with the limiting column 32. If unqualified, the cutting size is insufficient or out of tolerance (such as too short length, edge burrs, or bevel cutting), and the limiting column 32 cannot pass through the cutting hole 6 of the workpiece, or interferes with the limiting column 32.

[0019] The base plate 1 is made of a magnetic material, such as iron, and is designed to attract the magnets at the bottom of the base 31, thereby securing the bottom of the base 31. When testing different types of cut workpieces, the cutting holes of the standard sample of that model are first calibrated on the base plate 1. Then, each error-proofing module 3 is placed in the calibrated position. Each limit post 32 corresponds to the cutting hole 6 of the workpiece. During the testing process, it is only necessary to align the cutting hole 6 of the cut workpiece with each limit post 32, so that the limit post 32 passes through the corresponding cutting hole 6.

[0020] A guide head 33 is provided on the top of the limiting column 32 . The cross-sectional area of the guide head 33 increases from top to bottom, and plays a guiding role when the cut end of the workpiece is inserted into the limiting column 32 .

[0021] Since the shapes of the cutting holes 6 are different, when calibrating the limit column 32, not only the center point needs to be consistent with the cutting hole 6, but the corresponding angle also needs to be consistent with the cutting hole 6 to ensure complete consistency. In the present invention, at least three sliding cavities 37 are set through the base 31, preferably three, distributed in an equilateral triangle. The interior of the sliding cavity 37 is slidably connected to a slider 38, and the bottom of the slider 38 is installed with a universal ball wheel 34. Before the calibration position is determined, the universal ball wheel 34 is in rolling contact with the base plate 1. At this time, the base 31 is suspended and parallel to the base plate 1, so the base 31 and the entire error-proofing module 3 are movable.

[0022] The slider 38 is internally slidably connected to the insertion rod 39, and the lower end of the insertion rod 39 is installed with an anti-slip pad 312. The anti-slip pad 312 is located on the upper side of the universal ball wheel 34. Before the calibration position is determined, the anti-slip pad 312 is not in contact with the universal ball wheel 34, and the universal ball wheel 34 is movable at this time; after the calibration position is determined, the anti-slip pad 312 is in contact with the universal ball wheel 34, and the universal ball wheel 34 is locked and cannot be moved.

[0023] A first spring 310 is connected between the slider 38 and the top of the inner wall of the sliding cavity 37. A second spring 311 is connected between the slider 38 and the top of the insertion rod 39. Both the first spring 310 and the second spring 311 are tension springs. A locking assembly is provided on one side of the sliding cavity 37. The locking assembly includes an electric telescopic rod 36, at the end of which is mounted a top block 316. The top block 316 has a pointed front end and sloped upper and lower surfaces. A sloped surface 315 is provided on the side of the slider 38 near the top block 316. The top end of the sloped surface 315 is connected to a horizontal surface, with a wedge block 314 located above this horizontal surface. The sloped surface 315 mates with the bottom slope of the top block 316. A wedge block 314 is fixed to the side of the insertion rod 39 near the top block 316. The bottom slope of the wedge block 314 is connected to a horizontal surface. The top slope of the top block 316 is adapted to the wedge block 314. The wedge block 314 is located above the slider 38. The base 31 has a cavity 35 inside. The electric telescopic rod 36 is installed in the cavity 35. The cavity 35 also houses a power supply and a wireless control unit, which controls the movement of the electric telescopic rod 36 through external wireless control.

[0024] Before the calibration position is determined, the telescopic end of the electric telescopic rod 36 is extended. At this time, the top block 316 is inserted between the wedge block 314 and the slider 38, and is located between the horizontal sections of the wedge block 314 and the slider 38. The first spring 310 and the second spring 311 are both in a stretched state, and the anti-slip pad 312 does not contact the universal ball wheel 34, allowing the universal ball wheel 34 to move. During calibration, each error-proofing module 3 is moved and the limiting column 32 of each error-proofing module 3 is inserted into the cutting hole 6 of the workpiece 5. Since the workpiece is mostly made of plastic film, the plastic film needs to be stretched straight to accurately calibrate the hole position. The outer side of the base plate 1 is surrounded by a frame 2. The frame 2 is made of a magnetic material, such as metal iron, and a magnetic strip 4 is placed on the frame 2. The two sides of the workpiece are pressed against the frame 2 by the magnetic strip 4 to fix the side. The other side of the workpiece is manually pulled taut and straightened to make the workpiece flat. During this process, the error-proofing module 3 moves with the rolling of the universal ball wheel 34, thus completing the calibration. The frame 2 is higher than the top of the base 31 to ensure that the workpiece is flat as a whole.

[0025] When calibration is complete, the position should be locked as soon as possible, and the electric telescopic rod 36 should be activated, and the top block 316 should be pulled back. During this process, when the top block 316 and the wedge block 314 are offset, the insertion rod 39 is no longer lifted by the top block 316. Under the tension of the second spring 311, the insertion rod 39 descends, causing the anti-slip pad 312 to abut the top of the universal ball wheel 34, locking the universal ball wheel 34 and preventing it from rolling. As the top block 316 continues to move back, the bottom of the top block 316 contacts the inclined surface 315. During the movement, the slider 38 is pulled upward by the first spring 310, and the universal ball wheel 34 also moves upward. Finally, the universal ball wheel 34 is pulled into the sliding cavity 37. At this time, the bottom of the base 31 contacts the bottom plate 1, and the magnet at the bottom of the base 31 is attracted to the bottom plate 1, thereby firmly fixing the error-proofing module 3. It is important to note that each electric telescopic rod 36 is activated synchronously to ensure the consistent movement of each slider 38.

[0026] After completing the above work, you can start the inspection of this type of workpiece.

[0027] When changing models, the position needs to be recalibrated and the electric telescopic rod 36 is activated again to extend the telescopic end of the electric telescopic rod 36. During the process of the ejection of the top block 316, the slider 38 is ejected downward through interaction with the inclined surface 315. When the top block 316 moves to the horizontal surface above the inclined surface 315, the slider 38 is locked. At this time, the universal ball wheel 34 is ejected and protrudes from the bottom of the base 31. As the ejection of the top block 316 continues, the ejection block 314 is pushed upward, thereby lifting the insertion rod 39, so that the anti-slip pad 312 is separated from the universal ball wheel 34. At this time, the universal ball wheel 34 can move. When the ejection block 316 moves to the horizontal surface of the bottom of the wedge block 314, the wedge block 314 is locked. A notch 313 is provided on one side of the insert rod 39 near the top block 316, and the notch 313 is adapted to the end of the top block 316. Finally, the end of the top block 316 is inserted into the notch 313. At this time, the new model of workpiece can be calibrated using the above method by moving the universal ball wheel 34.
