Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a flat die-cutting machine for light-shielding tape. Background Technology

[0002] Light-shielding tape is a key auxiliary material in the assembly process of electronic product screens. It is mainly used to prevent light leakage from the screen and reflections from internal components, therefore, it requires extremely high dimensional accuracy and surface cleanliness. In existing technologies, light-shielding tape is typically cut using a flatbed die-cutting machine. After die-cutting, the finished tape often remains flat on the support plate, adhering to the surrounding waste bins. Operators must manually peel the tiny pieces of finished tape from the waste bins using tools such as tweezers. This process is not only inefficient, severely impacting production rhythm, but also highly susceptible to deformation, wrinkling, and even damage to the adhesive layer on the back due to uneven force during peeling and picking, leading to product scrap. Furthermore, manual operation introduces the risk of contamination from dust, fingerprints, and other contaminants, making it difficult to meet the high cleanliness requirements of production. Utility Model Content

[0003] The main objective of this invention is to provide a flatbed die-cutting machine for light-shielding tape to solve the problems raised in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, a flatbed die-cutting machine for light-shielding tape is provided, comprising an unwinding roller and a take-up roller, and further comprising: Die-cutting section, the die-cutting section being used to die-cut light-shielding tape into a preset shape; The supporting part is located below the die-cutting part and provides support for the die-cutting part. The two work together to die-cut the light-shielding tape. The lifting part is located inside the supporting part and can move up and down within the supporting part. When the die-cutting part presses down to die-cut the light-shielding tape, the lifting part is pressed down into the supporting part by the die-cutting part; when the die-cutting part leaves the supporting part, the lifting part springs back and lifts up the finished light-shielding tape after die-cutting.

[0005] Furthermore, the supporting part includes a supporting plate, and the upper surface of the supporting plate is provided with a plurality of grooves for accommodating the lifting part. A spacer ridge is formed between two adjacent grooves, and the spacer ridge provides a reaction force for the die-cutting part.

[0006] Furthermore, two front supports and two rear supports are fixedly provided at both ends of the upper surface of the support plate. The two front supports are used to install the unwinding roller, and the two rear supports are used to install the winding roller.

[0007] Furthermore, guide rollers are provided at both the front and rear of the die-cutting section, and the guide rollers are rotatably mounted on the support plate.

[0008] Furthermore, a die-cutting frame is provided above the support plate, and a hydraulic cylinder is fixedly provided on the top of the die-cutting frame. The piston rod of the hydraulic cylinder slides through the die-cutting frame to push the die-cutting part to move up and down.

[0009] Furthermore, a plurality of guide posts are slidably provided on the die-cutting frame, and the bottom of the guide posts is fixedly connected to the die-cutting part.

[0010] Furthermore, the die-cutting part includes a die-cutting plate, on which a plurality of die-cutting cutters are detachably provided, and the lower surface edge of the die-cutting cutters is fixedly provided with a blade.

[0011] Furthermore, each die-cutting tool is provided with a corresponding lifting part below it; the lifting part includes a lifting plate, and a through notch is provided on one side of the lifting plate.

[0012] Furthermore, a groove is provided on the upper surface of the lifting plate, and a number of elastic balls are fixedly disposed in the groove. A number of elastic sheets are also fixedly disposed on the upper surface of the lifting plate.

[0013] Furthermore, a plurality of springs are fixedly provided on the lower surface of the lifting plate, and the lower surface of the springs is fixedly connected to the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention features a liftable jack within the support section. After die-cutting, the jack automatically lifts the finished light-shielding tape, separating it from the surrounding waste bin and raising it to an easily accessible height. This structure fundamentally alters the relative position of the finished product and the support plate, achieving initial automatic separation of the finished product from the waste. Operators or robotic arms can easily and quickly pick up the finished product without tedious manual peeling, significantly improving picking efficiency and effectively avoiding product deformation, adhesive layer damage, and human contamination that can occur during manual peeling, thus ensuring product quality and yield.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] This embodiment provides a flatbed die-cutting machine for light-shielding tape, such as... Figure 1 As shown, it includes a die-cutting frame 1. Below the die-cutting frame 1, there is a support 7 for carrying and conveying the light-shielding tape. Specifically, the core component of the support 7 is a horizontally arranged support plate 71.

[0019] To achieve automatic feeding and waste recycling of the light-shielding tape, two front supports 2 and two rear supports 3 are fixedly installed at both ends of the upper surface of the support plate 71. An unwinding roller 4 is rotatably connected between the two front supports 2, and the raw material of the light-shielding tape to be die-cut is wound on it. A take-up roller 8 is also rotatably connected between the two rear supports 3, used to collect the waste material left after die-cutting. For power, a first motor (not shown in the figure) driving the unwinding roller 4 is installed inside one of the front supports 2, and a second motor (not shown in the figure) driving the take-up roller 8 is installed inside one of the rear supports 3.

[0020] To ensure that the light-shielding tape remains in close contact with the surface of the support plate 71 during transport and to prevent the material from being pulled downwards and deformed during die-cutting, a first guide roller 9 and a second guide roller 10 are rotatably mounted on the support plate 71, located on the front and rear sides of the die-cutting station, respectively. The lower surfaces of the first guide roller 9 and the second guide roller 10 are slightly higher than the upper surface of the support plate 71, thereby pressing the passing light-shielding tape moderately against the support plate 71 to keep it flat.

[0021] The die-cutting section 6, used for performing the cutting function, is located directly above the support plate 71. A hydraulic cylinder 12, serving as a power source, is fixedly mounted on the top of the die-cutting frame 1. The piston rod of the hydraulic cylinder 12 extends downwards and slidably passes through the top crossbeam of the die-cutting frame 1, connecting to the die-cutting section 6 below. To ensure the die-cutting section 6 remains stable and vertical during lifting and lowering, multiple guide pillars 11 are vertically slidably mounted on the die-cutting frame 1, with their bottoms fixedly connected to the die-cutting section 6. When the die-cutting section 6 reaches its lowest point, the tops of the guide pillars 11 remain within the guide holes of the die-cutting frame 1, thus providing stable guidance throughout the entire process.

[0022] like Figure 3 As shown, the die-cutting section 6 specifically includes a die-cutting plate 61, and several die-cutting blades 62 are detachably mounted on the lower part of the die-cutting plate 61. The die-cutting blades 62 are fixed by screws or other means, making it easy to replace the die-cutting blades 62. A sharp blade 63 is fixedly provided on the edge of the lower surface of each die-cutting blade 62, and the shape of the blade 63 is completely consistent with the shape of the desired finished product.

[0023] like Figure 2 As shown, the upper surface of the support plate 71 has several grooves 72 for accommodating the lifting part 5. Spacer ribs 73 are formed between adjacent grooves 72. The upper surfaces of these spacer ribs 73 are flush with the upper surface of the support plate 71, and their positions are directly opposite the cutting edge 63, so that when the die-cutting part 6 presses down, the cutting edge 63 of the die-cutting tool 62 can precisely press and cut on the spacer ribs 73, thereby using the reaction force provided by the spacer ribs 73 to cut the light-shielding tape.

[0024] The lifting section 5 is used for automatic lifting, and a corresponding lifting section 5 is provided below each die-cutting cutter 62. For example... Figure 4 As shown, the lifting part 5 mainly includes a lifting plate 51. Several springs 53 are fixedly connected to the lower surface of the lifting plate 51, and the bottom ends of the springs 53 are fixedly connected to the support plate 71 at the bottom of the receiving groove 72. In its natural state, the elastic force of the springs 53 drives the upper surface of the lifting plate 51 to a position slightly higher than the upper surface of the support plate 71, making it convenient to pick up the finished light-shielding tape. When the die-cutting part 6 presses down to perform die-cutting, the die-cutting plate 61 will simultaneously press the lifting plate 51, causing it to overcome the elastic force of the springs 53 and descend into the receiving groove 72 without affecting the die-cutting operation. When the die-cutting is completed and the die-cutting part 6 rises away, the lifting plate 51 immediately rises under the rebound action of the springs 53, thereby lifting the finished light-shielding tape that has been die-cut and is located on it, separating it from the surrounding waste frame.

[0025] To facilitate the handling of the lifted finished product by operators or robotic arms, a through-hole 52 is provided on one side of the lifting plate 51, providing space for tools to enter. To increase the friction between the lifting plate 51 and the finished tape during lifting and prevent slippage, a groove 54 is provided on the upper surface of the lifting plate 51, within which multiple elastic balls 55 made of a high-friction coefficient elastic material such as rubber are fixed. Simultaneously, several elastic sheets 56, also made of a high-friction coefficient elastic material, are fixed on the upper surface of the lifting plate 51. The upper surfaces of the elastic balls 55 and elastic sheets 56 are slightly higher than the upper surface of the lifting plate 51 in their natural state, ensuring effective contact with the finished tape and providing sufficient adhesion.

[0026] In order to allow the waste material to easily pass over the lifting plate 51 and be wound up by the winding roller 8, a slope 57 is provided above the side of the lifting plate 51 facing the unwinding roller 4. When the winding roller 8 pulls the waste material forward, the waste material rises along the slope 57 and passes over the lifting plate 51.

[0027] The working process of this utility model is as follows: The light-shielding tape is drawn out from the unwinding roller 4, flattened on the support plate 71 by the first guide roller 9, passes through the die-cutting station between the die-cutting section 6 and the support section 7, then passes through the second guide roller 10, and is finally wound up by the take-up roller 8. After the equipment is started, the hydraulic cylinder 12 drives the die-cutting section 6 to press down, and the blade 63 cuts the light-shielding tape on the spacer edge 73. At the same time, the lifting section 5 is pressed down. After the die-cutting is completed, the die-cutting section 6 rises back, and the lifting section 5 immediately lifts the finished product under the action of the spring 53. At this time, the operator can easily pick up the finished product. Then the take-up roller 8 pulls the waste box forward one station, and the equipment enters the next working cycle.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
