Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting, in particular to a full-automatic die-cutting and inspecting integrated machine. Background Art

[0002] Die-cut product inspection plays a vital role in a wide range of industries, including electronics, electrical appliances, copiers, digital cameras, laptops, mobile phones, automobiles, and instrumentation. These products often use die-cut components for insulation, fixing, dust protection, vibration reduction, and sealing. As the manufacturing industry continues to advance toward automation, intelligence, high precision, high speed, and flexibility, inspection standards for die-cut products are also rising for issues such as dimensional accuracy, missing or insufficient glue, clogged holes, and surface defects. The diversity and complexity of die-cut products, including variations in shape, color, and material, further increase the challenges of inspection.

[0003] Traditional die-cutting inspection systems currently on the market rely primarily on the contrast of the object surface to work. When ideal lighting conditions (such as the angle and wavelength of light) cannot be achieved, the system struggles to accurately identify the required key features from a complex background, thus affecting its stability and accuracy. Furthermore, such inspection systems are powerless when faced with objects of the same color against a black background, and lack three-dimensional height information, limiting them to geometric dimension measurements within a two-dimensional plane. This means they are unable to complete height-related inspection tasks, such as surface depressions or protrusions and thickness measurements.

[0004] In addition, traditional die-cutting inspection equipment is mostly semi-automatic, and unqualified products found during the inspection process need to be manually removed, which is difficult to meet the needs of modern enterprises for die-cutting automation. Utility Model Content

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1-6The figure shows a fully automatic die-cutting and inspection-rejecting machine provided by an embodiment of the present invention, which at least includes a base 1, on which are provided a material unwinding mechanism 2, a film-collecting mechanism 3, a roller mechanism, a material-receiving mechanism 5, a film-discharging mechanism 6, a 3D image acquisition unit, a material-rejecting mechanism 8, and an industrial computer 101. The material unwinding mechanism 2 is used to unwind the die-cut product to be inspected; the film-collecting mechanism 3 is used to rewind the film on the die-cut product to be inspected; the material-receiving mechanism 5 is used to rewind the die-cut product after inspection; the film-discharging mechanism 6 is used to unwind the film and cover the die-cut product after inspection; the roller mechanism is used to loosen or press the film; the 3D image acquisition unit is used to acquire and generate a 3D image of the die-cut product to be inspected; the industrial computer 101 is used to identify the 3D image and mark the identified defective die-cut products; and the material-rejecting mechanism 8 is used to reject the defective die-cut products marked by the industrial computer 101.

[0031] By using a 3D image acquisition unit to inspect the die-cut products to be inspected, the spatial position and surface information of the die-cut products can be identified, thereby enabling the detection of defects such as die-cut product size, height, chamfers, excess glue, insufficient glue, blocked holes, foreign matter, and surface irregularities. This is unaffected by the contrast of the target object and provides high detection versatility. In addition, the present invention also provides a rejection mechanism that can automatically reject defective die-cut products marked by the industrial control computer 101, thereby significantly reducing labor input and saving labor costs.

[0032] In some embodiments, the 3D image acquisition unit includes two 3D laser sensors 71, which are placed on the upper and lower sides of the die-cut product to be inspected. In this way, the 3D image of the die-cut product to be inspected can be more accurately acquired, thereby ensuring the accuracy of subsequent rejection.

[0033] In some embodiments, the picking mechanism 8 includes a vertical motion component 81 and a mounting plate 82, and the vertical motion component 81 is used to drive the mounting plate 82 to move along the vertical motion direction; the mounting plate 82 is provided with a unwinding wheel 83, a picking head 84, a speed wheel 85 and a winding wheel 86, and the unwinding wheel 83 is wound with tape, and the head of the picking head 84 is set toward the die-cut product to be inspected. The free end of the tape on the unwinding wheel 83 passes through the head of the picking head 84 and the speed wheel 85 in turn and is wound on the winding wheel 86. The speed wheel 85 is used to drive the tape to move, and the winding wheel 86 is used to wind up the tape. The tape is sticky on the side facing the external material tape. Specifically, when a defective die-cut product marked by the industrial computer 101 passes under the reject head 84, the vertical motion component 81 drives the mounting plate 82 to move downward in the vertical direction. When the tape on the reject head 84 contacts the defective die-cut product, the vertical motion component 81 drives the mounting plate 82 to move in the opposite direction. During the above process, the defective die-cut product will be carried away by the tape, thereby achieving the rejection of the defective die-cut product. In addition, during the above process, the speed-matching wheel 85 drives the tape to move so that the speed of the tape movement is consistent with the speed of the defective die-cut product. This can reduce the impact between the two when they come into contact and ensure the reliability of rejection. Specifically, the head of the reject head 84 is provided with a roller, which can further reduce the resistance of the tape movement.
