Description

Technical Field

[0001] This utility model relates to the field of touch screen manufacturing technology, and in particular to a pressure resistance testing device for touch screen manufacturing. Background Technology

[0002] In the touch screen manufacturing process, pressure testing equipment is widely used to perform pressure testing on touch screens. Touch screens, also known as "touch panels" or "touch screens," are inductive liquid crystal display devices that can receive touch input signals. Today, commercially available touch screen technologies include resistive touch screens, capacitive touch screens, and infrared touch screens. Pressure testing equipment is also used in the touch screen manufacturing process.

[0003] When using existing pressure testing equipment, the touch screen is placed on the operating panel and fixed. After fixing, the top plate is used to press the touch screen to perform pressure testing. After the pressure test, the bottom of the operating box is usually cleaned.

[0004] However, existing pressure testing equipment typically only cleans the bottom of the control box, failing to clean impurities on the top of the control panel, resulting in poor cleaning and unsatisfactory performance. To address these issues, a pressure testing device for touch screen production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure resistance testing device for touch screen production, which solves the problem in the background technology that the bottom of the operation box is generally cleaned, but the impurities on the top of the operation panel are not cleaned, resulting in poor cleaning effect and poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure resistance testing device for touch screen production, comprising an operating box, a filter box fixedly connected to one side of the outer wall of the operating box, a fan penetrating and fixedly connected to the front side of the outer wall of the filter box, a filter plate penetrating and slidably connected to the top of the filter box, a flexible tube penetrating and fixedly connected to the rear side of the outer wall of the filter box, a rigid tube penetrating and fixedly connected to one side of the outer ring of the flexible tube, a rigid tube penetrating and fixedly connected to the bottom of the flexible tube, uniformly distributed suction tubes penetrating and fixedly connected to one side of the outer ring of the two rigid tubes, and U-shaped scrapers fixedly connected to both ends of the top rigid tube. A fixed box is fixedly connected to the rear side of the outer wall of the operation box. A first motor is fixedly connected to the rear side of the outer wall of the fixed box. The output end of the first motor passes through the fixed box and is fixedly connected to a sprocket. A sprocket is rotatably connected between the inner walls of the fixed box. A chain is provided between the two sprockets. A sweeping rod is fixedly connected to the front side of the chain through the fixed box. A first cylinder is fixedly connected to the top of the inner wall of the operation box. An L-shaped plate is fixedly connected to the output end of the first cylinder. A pressure sensor is provided at the top of the inner wall of the L-shaped plate. A test block is provided at the bottom of the pressure sensor. A collection assembly is provided on the left side of the outer wall of the operation box.

[0007] By adopting the above technical solution, when it is necessary to clean up touch screen fragments, the first cylinder and the third cylinder are activated.
