Abstract
Description
Technical Field
[0001] This application relates to the technical field of laser cutting equipment, and in particular to a laser cutting machine pad. Background Technology
[0002] FPC boards, also known as flexible printed circuit boards, are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by their thinness and flexibility. However, their easy bending can sometimes be a drawback.
[0003] In existing technologies, FPC flexible circuit board forming is divided into two methods: laser cutting and die punching. However, during the product development stage, laser cutting is the preferred method, and for some products, due to structural and quality requirements, laser cutting is still required to complete the forming task in the mass production stage. Currently, laser cutting has the following defects that affect production;
[0004] The lower half of commonly used laser cutting instruments in the current technology has a honeycomb structure. The back of the honeycomb structure has a vacuum suction force, which allows the carbon black or FPC board fragments cut by the laser to be vacuumed away from the FPC board through the honeycomb structure to prevent residue from adhering to the FPC board. As a result, the existing metal honeycomb panels have a limited number of uses and need to be replaced frequently to ensure the cutting effect, which leads to high maintenance costs. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a laser cutting machine pad that has the advantages of long service life, easy cleaning and replacement, and reduced production costs.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A laser cutting machine pad includes a substrate, on which a plurality of vacuum suction holes are evenly distributed, and a limiting cloth layer is laid on the top of the substrate.
[0008] The limiting fabric layer includes a fiber cloth woven from PTFT fiber filaments and a fixing frame disposed around the periphery of the fiber cloth.
[0009] A fastener is provided between the fixed frame and the base plate.
[0010] To achieve the above technical solution, after the fiber cloth layer is placed on the substrate, it can block the vacuum suction holes, thereby ensuring that the suction force of the vacuum suction holes is evenly distributed through the fiber cloth layer, thus ensuring the stability of the adsorption. After the fiber cloth is fixed by the fixing frame, it is fixed to the substrate by the fixing component, so that the product is placed on the fiber cloth for laser cutting. During the cutting process, the laser energy is focused on the fiber cloth, and the waste generated during cutting will adhere to the limiting cloth. When the product positioning becomes dirty after long-term use, according to the characteristics of PTFT material, the entire limiting cloth layer can be removed from the substrate and cleaned in an ion cleaning machine, thereby ensuring the cleanliness of the fiber cloth layer and thus ensuring the cutting effect.
[0011] As a preferred embodiment of this application, the fastener includes a fixing screw, and the fixing frame is provided with a positioning hole for the fixing screw to pass through.
[0012] The above technical solution is achieved by screwing the fixing screws onto the substrate, thereby fixing the fixing frame onto the substrate.
[0013] As a preferred embodiment of this application, an adhesive layer for mutual bonding is provided between the fixing frame and the substrate.
[0014] The above technical solution ensures the reliability and adhesion of the fiber cloth layer to the substrate, thus ensuring the smoothness of the fiber cloth and the positioning effect.
[0015] As a preferred embodiment of this application, a lifting groove is provided on the base plate below the fixing frame, a lifting rod is provided in the lifting groove, a pressing rod is provided on the side wall of the base plate, an inclined guide surface is provided on the pressing rod, and the bottom wall of the lifting rod is in contact with the inclined guide surface.
[0016] The above technical solution enables personnel to press the pressing rod, which drives the lifting rod to move upward under the action of the inclined guide surface, thereby lifting the positioning frame away from the base plate, making it easier for personnel to replace it.
[0017] In summary, this application includes at least one of the following beneficial technical effects:
[0018] 1. After the fiber cloth layer is placed on the substrate, it can block the vacuum suction holes, so that the suction force of the vacuum suction holes is evenly distributed through the fiber cloth layer, thus ensuring the stability of the adsorption. After the fiber cloth is fixed by the fixing frame, it is fixed on the substrate by the fixing component, so that the product is placed on the fiber cloth for laser cutting. During the cutting process, the laser energy is focused on the fiber cloth, and the waste generated by cutting will adhere to the limiting cloth. When the product positioning is dirty after long-term use, according to the characteristics of PTFT material, the entire limiting cloth layer can be removed from the substrate and cleaned in an ion cleaning machine, thus ensuring the cleanliness of the fiber cloth layer and ensuring the cutting effect.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0025] This application discloses a laser cutting machine pad. (Refer to...) Figure 1 The laser cutting machine pad includes a substrate 1, on which a plurality of vacuum suction holes 2 are evenly distributed. A layer of fiber cloth 3 is laid on the top of the substrate 1. That is, after the fiber cloth 3 is covered on the substrate 1, it can block the vacuum suction holes 2, so that the suction force of the vacuum suction holes 2 is evenly distributed through the fiber cloth 3, thereby ensuring the stability of the adsorption.
[0026] The fiber cloth layer 3 comprises a fiber cloth 3 woven from PTFT fiber filaments and a fixing frame 4 disposed around the fiber cloth 3. The fixing frame 4 can be made of conventional chemical fiber fabric or woven metal wire. The limiting cloth and the fixing frame 4 are bonded together with adhesive. A fixing element is provided between the fixing frame 4 and the substrate 1. That is, after the fiber cloth 3 is fixed by the fixing frame 4, it is fixed to the substrate 1 by the fixing element, so that the product is placed on the fiber cloth 3 for laser cutting. During the cutting process, the laser energy is focused on the fiber cloth 3, and the waste generated during cutting will adhere to the limiting cloth. When the product positioning becomes dirty after long-term use, according to the characteristics of PTFT material, the entire limiting cloth layer can be removed from the substrate 1 and cleaned in an ion cleaning machine, thereby ensuring the cleanliness of the fiber cloth layer 3 and thus ensuring the cutting effect.
[0027] The fastener includes a fixing screw 5. The fixing frame 4 is provided with a positioning hole for the fixing screw 5 to pass through. That is, the fixing screw 5 is screwed onto the substrate 1, thereby achieving the effect of fixing the fixing frame 4 onto the substrate 1.
[0028] An adhesive layer is provided between the fixing frame 4 and the substrate 1 for mutual bonding, thereby further ensuring the firmness and adhesion of the fiber cloth 3 layer on the substrate 1, thereby ensuring the smoothness of the fiber cloth 3, and thus ensuring the positioning effect.
[0029] To facilitate the replacement of the three layers of cleaning fiber cloth, a lifting groove is provided on the base plate 1 below the fixing frame 4, and a lifting rod 6 is installed in the lifting groove. A pressing rod 7 is provided on the side wall of the base plate 1, and an inclined guide surface 8 is provided on the pressing rod 7. The bottom wall of the lifting rod 6 is in contact with the inclined guide surface 8, so that when a person presses the pressing rod 7, the lifting rod 6 can be driven to move upward under the action of the inclined guide surface 8, thereby lifting the positioning frame away from the base plate 1, which facilitates replacement. A spring 9 is provided between the pressing rod 7 and the base plate 1 so that the pressing rod 7 returns to its original position under the action of the pressing rod 7 after the person presses it.
[0030] The implementation principle of a laser cutting machine pad in this embodiment is as follows: After the fiber cloth 3 layers are covered on the substrate 1, they can block the vacuum suction hole 2, so that the suction force of the vacuum suction hole 2 is evenly distributed through the fiber cloth 3 layers, thereby ensuring the stability of the adsorption; after the fiber cloth 3 is fixed by the fixing frame 4, it is fixed on the substrate 1 by the fixing component, so that the product is placed on the fiber cloth 3 for laser cutting. During the cutting process, the laser energy is focused on the fiber cloth 3, and the waste generated by cutting will adhere to the limiting cloth. When the product positioning is dirty after long-term use, according to the characteristics of PTFT material, the entire limiting cloth layer can be removed from the substrate 1 and cleaned in an ion cleaning machine, thereby ensuring the cleanliness of the fiber cloth 3 layers and thus ensuring the cutting effect.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
