Description

Technical Field

[0001] This invention relates to the field of prism sheet processing technology, and in particular to a processing equipment and process for reducing prism sheet dust. Background Technology

[0002] Prism sheets are used in liquid crystal displays to improve the brightness of the front of the screen. Prism sheets themselves have a structure and require cutting and processing.

[0003] Place the prism sheet on the worktable of the cutting equipment and secure it using clamps or suction cups. Ensure the prism sheet will not move or deform during the cutting process. Start the cutting equipment and cut according to the preset cutting plan.

[0004] However, when the cutting equipment cuts the prism sheet body, the edge structure of the prism sheet is broken by external force, which will generate some dust. Even if the dust is cleaned by the washing machine, it cannot be completely cleaned. The dust that is not cleaned falls on the surface of the prism sheet during the transportation process. Due to the stacking and transportation, the dust will cause defects on the surface of the prism sheet due to gravity, resulting in product defects. Summary of the Invention

[0005] The purpose of this invention is to provide a processing equipment and process for reducing powder and debris from prism sheets, which solves the problem that cutting the prism sheet body with a cutting tool generates powder and debris, creating defects on the surface of the prism sheet and leading to product defects.

[0006] To achieve the above objectives, the present invention provides a processing method for producing fewer prism sheet dust, comprising the following steps: Place the prism sheet material roll and pull one end of the prism sheet material roll; While traction is being performed, the prism sheet material is cut using a die to obtain prism sheet material; The remaining trimmed material is pulled by the pressure roller and then wound up by the take-up roller; The cut prism sheet is lifted by the conveyor belt and moved backward, so that the two ends of the prism sheet pass through the electric arc generator to melt and solidify the powder on the edge of the prism sheet, and then it is cleaned by the dust roller of the washing machine. After cleaning, the materials are manually received and placed on a receiving cart for stacking.

[0007] The steps of placing the prism sheet material roll and pulling one end of the prism sheet material roll further include: Place the prism sheet raw material roll on the feeding rack, and fit the raw material core into the designated position on the feeding rod. Inflate the air inlet of the feeding rod to make it expand and lock the raw material core. Pull one end of the prism sheet raw material roll around the three tension rods and adjust the feeding tightness so that one end of the prism sheet raw material roll passes through the pressure roller.

[0008] During the traction process, the prism sheet material is cut using a die to obtain a prism sheet. The steps also include: Before cutting, install the designed die into the designated slot on the cutting equipment, and operate the air pressure system of the cutting equipment to clamp the die. After the die is clamped, the cutting equipment parameters are adjusted so that the die makes a reciprocating up and down punching motion. Each punching motion will process a prism sheet of a specified size.

[0009] The process further includes cleaning via the dust-collecting roller of the washing machine, and the steps also include: The adhesive roller of the washing machine directly contacts the upper and lower parts of the prism sheet material. It is a blue rubber roller with weak adhesion. The other end of the blue rubber roller contacts the white adhesive paper, which has high viscosity and will remove foreign objects from the blue rubber roller.

[0010] A processing device for reducing prism sheet dust includes a loading rack, a traction assembly, a die cutter, a conveyor belt, an arc generator, and a washing machine. The traction assembly is located behind the loading rack, the die cutter is located above the traction assembly, the conveyor belt is located behind the die cutter, the arc generator is located on both sides of the conveyor belt, and the washing machine is located behind the conveyor belt.

[0011] The traction assembly includes three tension rods, two pressure rollers, and a take-up roller. The three pressure rods are staggered between the loading frame and the die. The two pressure rollers are located on the front and rear sides of the die. The take-up roller is located above the pressure rollers.

[0012] The processing equipment for reducing prism sheet dust also includes a receiving cart, which is located behind the washing machine.

[0013] This invention discloses a processing equipment and process for reducing prism sheet dust. The raw prism sheet roll is placed on a feeding rack and pulled forward. After being cut by a die, it becomes individual prism sheet materials. The remaining edge material after edge trimming is pulled by a pressing roller and then wound up by a take-up roller. The take-up roller continuously rotates, gradually tightening the edge material. The cut sheet is then lifted by a conveyor belt and moved backward. When the two ends of the cut prism sheet pass through an electric arc generator, the edge dust is melted and solidified. It is then cleaned by a dust-adhesive roller in a washing machine. Finally, it is manually received and placed on a receiving cart for stacking. The electric arc of the electric arc generator occurs when a voltage is applied between two electrodes, creating an electric field between them. Air molecules in this space undergo "polarization." When the applied voltage is large enough, the electric field in this space will also be strong enough. The severe polarization of air molecules will lead to the generation of positive and negative ions. These positive and negative ions move in a direction under the influence of the strong electric field, forming a strong current, which generates a lot of heat, resulting in an electric arc. The electric arc effect can be controlled by adjusting the gap between the two electrodes and adjusting the output energy, thereby melting and solidifying the powder at the edge of the prism sheet and reducing the number of defects caused by powder.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows: Please see Figure 1 ,in, Figure 1This is a flowchart illustrating the steps of a prism sheet dust reduction process according to the first embodiment of the present invention. The present invention provides a prism sheet dust reduction process, comprising the following steps: S101: Place the prism sheet material roll and pull one end of the prism sheet material roll; S102: While traction is being performed, the prism sheet material is cut using the die 202 to obtain the prism sheet material; S103: The remaining edge material after cutting is pulled by the pressure roller 207 and then wound up by the take-up roller 208; S104: The cut prism sheet is lifted by the conveyor belt 203 and moved backward, so that the two ends of the prism sheet pass through the arc generator 204 to melt and solidify the powder on the edge of the prism sheet, and then pass through the dust roller of the washing machine 205 for cleaning. S105: After cleaning, the materials are manually received and placed on receiving cart 209 for stacking.

[0020] Specifically, firstly, the prism sheet raw material roll is placed on the feeding rack 201, with the core of the roll fitted into the designated position on the feeding rod. Air is then injected into the feeding rod's air inlet to expand and lock the core. The prism sheet is pulled around three tension rods 206. To ensure uniform feeding of the prism sheet, the feeding tension is adjusted. The prism sheet passes through the pressure roller 207, which primarily serves to pull the prism sheet forward. After being cut by the die 202, it becomes a separate prism sheet. Before cutting, the designed die 202 is installed into the designated slot on the equipment. The equipment's pneumatic system is operated to clamp the die 202. After clamping, the equipment parameters are adjusted to make the die 202 perform reciprocating up-and-down punching motions. Each punching operation produces a sheet of a specified size. After the edges of the prism sheet are cut, the remaining material is pulled by the pressing roller 207 and then wound up by the take-up roller 208. The take-up roller 208 rotates continuously to gradually tighten the material. The cut sheet is lifted by the conveyor belt 203 and moved backward. When the two ends of the cut prism sheet pass through the arc generator 204, the powder on the edge of the prism sheet is melted and solidified. Then it is cleaned by the dust roller of the washing machine 205. The dust roller of the washing machine 205 directly contacts the upper and lower parts of the prism sheet with blue rubber rollers, which have weak adhesion. The other end of the blue rubber roller contacts white dust paper, which has high viscosity and will remove foreign objects from the blue rubber roller to prevent secondary contamination. Finally, the material is manually received and placed on the receiving cart 209 for stacking.

[0021] The electric arc in the arc generator 204 is generated when a voltage is applied between two electrodes, creating an electric field that polarizes the air molecules in that space. When the applied voltage is sufficiently high, the electric field becomes strong enough, and this severe polarization leads to the generation of positive and negative ions. These ions move directionally under the influence of the strong electric field, forming a powerful current that generates significant heat, resulting in the electric arc. The arc effect is controlled by adjusting the gap between the electrodes and the output energy, melting and solidifying the powder at the edge of the prism sheet to reduce defects caused by the powder.

[0022] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 2 ,in, Figure 2 This is a schematic diagram of a processing device for reducing prism sheet dust according to a second embodiment of the present invention.

The loading rack 201 is used to hold the prism sheet raw material roll, the traction assembly is used to pull the prism sheet raw material roll forward, the die 202 is connected to the cutting equipment and performs reciprocating up and down punching action, each punching will process a prism sheet of a specified size, and the arc of the arc generator 204 is generated when a voltage is applied between two electrodes, then an electric field will be generated between the two electrodes, and the air molecules in this space will undergo "polarization". When the applied voltage is large enough, the electric field in this space will also be strong enough. The severe polarization of air molecules will lead to the generation of positive and negative ions. These positive and negative ions move in a directional manner under the influence of the strong electric field, forming a strong current, which generates a lot of heat, resulting in an electric arc. The electric arc effect can be controlled by adjusting the gap between the two electrodes and adjusting the output energy. The washing machine 205 cleans the cut prism sheets, and the conveyor belt 203 is used to transport the cut prism sheets.

[0024] The three clamping rods are staggered between the feeding frame 201 and the die 202; the two clamping rollers 207 are located on the front and rear sides of the die 202; and the take-up roller 208 is located above the clamping rollers 207. One end of the prism sheet raw material roll is pulled around the three clamping rods 206. To ensure uniform feeding of the prism sheet, the feeding tension is adjusted. The prism sheet passes through the clamping rollers 207, and after being pulled by the clamping rollers 207, it is wound up by the take-up roller 208, thus pulling the prism sheet forward.

[0025] Secondly, the receiving cart 209 is located behind the washing machine 205. The receiving cart 209 is used to place the processed prism sheets.

The take-up roller 208 rotates continuously to gradually tighten the edge material. The cut sheet is lifted by the conveyor belt 203 and moved backward. When the two ends of the cut prism sheet pass through the arc generator 204, the powder on the edge of the prism sheet is melted and solidified. Then it is cleaned by the dust roller of the washing machine 205.
