Description

Technical Field

[0001] The utility model relates to the field of die-cutting equipment, in particular to a die-cutting machine with an online detection function. Background Art

[0002] Traditional die-cutting refers to a cutting process for the post-processing of printed products. The die-cutting process can make printed products or other paper products into die-cutting plates according to pre-designed patterns for cutting, so that the shape of printed products is no longer limited to straight edges and right angles. Traditional die-cutting production uses die-cutting knives to combine die-cutting plates according to the patterns required by product design. Under the action of pressure, printed products or other plate-shaped blanks are rolled into the required shape or cut marks.

[0003] Die-cutting equipment is mainly divided into two categories: one is a large-scale die-cutting machine specially used for carton and color box packaging, and the other is a die-cutting machine used for precision electronic die-cutting products.

[0004] Existing die-cutting machines used for precision electronic die-cutting products detect defective products after die-cutting, and the inspection is done manually with the naked eye. This method has defects such as long inspection time and high probability of missed inspection. The reason is that defective products already exist in the film material before entering the die-cutting work. Utility Model Content

[0005] The purpose of the utility model is to provide a die-cutting machine with an online detection function, which can at least solve one of the above problems.

[0006] According to one aspect of the utility model, a die-cutting machine with an online detection function is provided, comprising at least:

Through the visual inspection device, online inspection can be realized, thereby monitoring the yield of the production process and preventing batch defects. In addition, since the device is arranged in front of the die-cutting device, unqualified products can be skipped online to avoid mixing with good products, which can effectively reduce the number of defective products and effectively improve the efficiency of subsequent manual inspection.

The lower mold mechanism is fixedly installed on the machine platform, the upper mold mechanism can be movably installed on the machine platform and cooperate with the lower mold mechanism, and the die-cut product collection mechanism is installed on the machine platform and cooperates with the lower mold mechanism.

[0021] In some embodiments, the die-cut product collection mechanism includes a collection trough and a guide trough. The collection trough is installed on the machine platform.

The upper inspection mechanism 42 and the lower inspection mechanism 43 operate synchronously. When the film material 8 with the die-cut product passes through the transparent plate 51, the first camera 421 and the second camera 431 take pictures respectively, and then send the data to the controller 44. The controller 44 analyzes and summarizes the inspection results to determine whether it is a defective product. If no defective product is found, a signal is sent to the die-cutting device 3, and the die-cutting device 3 performs normal cutting. On the contrary, if a defective product is found, the die-cutting device 3 directly skips. The above shooting results and analysis results can be displayed in real time on the display 45, which is convenient for users to monitor in real time.

In addition, since the device is arranged in front of the die-cutting device 3, unqualified products can be cut online to avoid mixing with good products, which can effectively reduce the number of defective products and effectively improve the efficiency of subsequent manual inspection.

[0054] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
