[0042] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] like Figures 1 to 4As shown, this embodiment provides a punching device for cutting a carrier containing cosmetic contact lenses into independent packages to facilitate the removal of individual cosmetic contact lenses. The punching device includes a base 100, a lifting member 200, a driving member 300, a plurality of tool holders 400, a plurality of cutting tools 500, and an adjusting member 600. Among them, the lifting member 200 is slidably arranged on the base 100 along the vertical direction; the driving member 300 is arranged on the base 100, and its output end is transmission-connected to the lifting member 200; a number of tool holders 400 are movably arranged at intervals on the lifting member 200 along the width direction, and the tool holder 400 is provided with a positioning portion 420, and a number of cutting tools 500 are correspondingly installed on the number of tool holders 400; the first mating surface of the adjusting member 600 has a number of first mating portions 610 arranged at intervals of a first size, and the second mating surface of the adjusting member 600 has a number of second mating portions 620 arranged at intervals of a second size; wherein the first size is larger than the second size, and the positioning portion 420 can cooperate with the first mating portion 610 or the second mating portion 620 to lock the tool holder 400 in the width direction. During the punching process, when the type of workpiece to be cut is changed, it is only necessary to change the face of the adjustment member 600 and move each tool holder 400 accordingly so that each positioning portion 420 is engaged with each first mating portion 610 or each second mating portion 620. This achieves the positioning of the tool holder 400 and can lock each tool holder 400, thereby improving punching efficiency, avoiding the need to replace the entire punching blade device, and reducing costs. The vertical direction is the up-down direction, and the width direction is the left-right direction.

[0044] To improve the assembly efficiency of the tool holder 400 and the adjustment member 600, they can be plugged in and out. For example, the tool holder 400 includes a mounting body 410 and a positioning protrusion protruding from the mounting body 410 and forming a positioning portion 420. The first matching portion 610 is a first groove; the second matching portion 620 is a second groove, and the positioning protrusion can be plugged into the first groove or the second groove. During assembly, it is only necessary to move each tool holder 400 to the corresponding position, and then match the adjustment member 600 with each tool holder 400 so that each positioning protrusion is plugged into each first groove or each second groove. In other embodiments, the positioning portion 420 can be a groove structure, and both the first matching portion 610 and the second matching portion 620 can be a protrusion structure.

[0045] The fixing method of the adjusting member 600 directly affects the efficiency of adjusting the distance between the cutting tools 500. In some embodiments, the top surface of the mounting body 410 forms a support portion, and a positioning protrusion is protruded from the support portion. When the positioning protrusion is located in the first groove or the second groove, the support portion is located on the lower side of the adjusting member 600 and supports the adjusting member 600. With the support portion supporting the adjusting member 600, the adjusting member 600 can be directly placed on each tool holder 400 during the assembly process. Each tool holder 400 supports the adjusting member 600 to achieve the connection between the tool holder 400 and the adjusting member 600, thereby avoiding the need to fix the adjusting member 600 separately and greatly improving the fixing efficiency of the adjusting member 600. In other words, the adjusting member 600 serves to limit the distance between each tool holder 400. The tool holder 400 can support the adjusting member 600, and the two are mutually restricted and interrelated, with a simple structure and easy assembly.

[0046] To enhance the stability of the adjustment member 600, the punching blade assembly includes a mounting member 700, which is mounted on the lifting member 200. When the positioning projection is in the first or second groove, the mounting member 700 is positioned below the adjustment member 600 and supports the adjustment member 600. In this embodiment, the mounting member 700 is positioned behind the positioning projection. The simultaneous support of the mounting member 700 and the blade holder 400 enhances the stability of the adjustment member 600. This also reduces the pressure on the blade holder 400, improves the structural stability of the blade holder 400, and ensures the reliability and accuracy of the spacing between the cutting tools 500.

[0047] The axis of the first groove extends in the vertical direction, the axis of the second groove extends in the vertical direction, and the positioning protrusion extends in the vertical direction, so as to facilitate disassembly and assembly in the vertical direction and improve disassembly and assembly efficiency.

[0048] To improve assembly efficiency, in some embodiments, the adjustment member 600 is made of a transparent material. This allows the position of the positioning portion 420 to be observed through the adjustment member 600 during assembly, facilitating fine-tuning of each tool holder 400 so that each positioning portion 420 is aligned with each first mating portion 610 or each second mating portion 620. The adjustment member 600 may be made of plastic.

[0049] In other embodiments, at least one first groove is partially connected to one of the second grooves in the vertical direction, so that when the first groove and the positioning portion 420 are engaged, the positioning portion 420 below can be observed from above through the second groove.

[0050] Considering the smoothness of movement of the tool holder 400 and the accuracy of spacing adjustment, the punching knife device includes a slide rail 810 and a slider 820. The slide rail 810 extends along the width direction and is fixed to the mounting member 700. The slider 820 is connected to the tool holder 400 and slides with the slide rail 810.

[0051] In this embodiment, there are four tool holders 400 and four cutting tools 500, and the four tool holders 400 and the four cutting tools 500 are connected one-to-one, and two slide rails 810 are provided; the two slide rails 810 are arranged at intervals in the vertical direction, and along the width direction, the two adjacent tool holders 400 are respectively slid on the two slide rails 810 through two sliders 820 one-to-one to avoid the width dimension of the slider 820 affecting the gap between the tool holders 400, so that the gap between each tool holder 400 can be as small as possible, thereby increasing the adjustable range of the distance between adjacent cutting tools 500.

[0052] The punching device also includes a pressing assembly 900, which is mounted on the lifting member 200 and can slide vertically, allowing the pressing end of the pressing assembly 900 to move below and above the cutter 500. During punching, the pressing assembly 900 first presses the workpiece to prevent it from shifting, thereby improving punching accuracy.

[0053] Specifically, the pressure assembly 900 includes a pressure plate 910 and a guide rod 920. The lifting member 200 is provided with a guide hole. The guide rod 920 is inserted into the guide hole and can move back and forth in the vertical direction relative to the lifting member 200. The lower end of the guide rod 920 is connected to the pressure plate 910. The lower end of the pressure plate 910 forms a pressure end. The pressure plate 910 is provided with a punching groove 911 that penetrates in the vertical direction, and the tool 500 can pass through the punching groove 911. In this embodiment, the upper end of the guide rod 920 is provided with a stop portion, and the outer diameter of the stop portion is larger than the outer diameter of the guide hole, thereby preventing the guide rod 920 from sliding down and out of the guide hole. During use, under the driving action of the driving member 300, the lifting member 200 is lowered, so that the pressure plate 910 first contacts the workpiece to be cut, and then the lifting member 200 continues to descend, the pressure plate 910 remains stationary, and the guide rod 920 rises relative to the lifting member 200, and finally the tool 500 cuts the workpiece to be cut to complete the punching process.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
