DETAILED DESCRIPTION

[0023] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, a screen thermal cutting and disassembly device for a touch screen device comprises a cabinet 1, a partition plate 2 is arranged inside the cabinet 1, a jig 3 for placing the touch screen is arranged on the partition plate 2, a thermal cutting and disassembly mechanism 4 is arranged around the jig 3, and a smoke exhaust mechanism 5 is arranged above the jig 3. Specifically, a screen thermal cutting and disassembly device for a touch screen device is designed to efficiently and safely complete the disassembly of the touch screen while reducing the pollution to the operating environment. The cabinet 1, as the main frame of the entire device, is made of high-strength and corrosion-resistant materials to ensure the stability and durability of the device. The surface of the cabinet 1 is treated with anti-slip and anti-scratch treatment, which is both beautiful and practical. The partition plate 2 divides the internal space of the cabinet 1 into different functional areas, thereby improving the space utilization rate. It is used to support the jig 3 to ensure that the touch screen remains stable during the disassembly process. The jig 3 is a fixing device specially designed for the touch screen, and its shape and size perfectly match the touch screen to ensure that the touch screen will not shake or shift during the disassembly process. The hot-cut screen disassembly mechanism 4 is one of the core components of the device. It uses high-temperature heating to soften the adhesive between the touch screen and the internal components, thereby achieving non-destructive disassembly. Considering the smoke and harmful gases that may be generated during the hot-cut screen disassembly process, a smoke exhaust mechanism 5 is designed on the top of the device. The smoke exhaust mechanism 5 uses a powerful fan and an efficient filtration system to quickly discharge the generated smoke and harmful gases to the outside of the cabinet 1, keeping the operating environment clean and the air fresh. This touch screen device screen hot-cut screen disassembly equipment has broad application prospects in the field of touch screen disassembly due to its high efficiency, safety, and environmental protection.

[0025] Combination Figure 1 ,Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 , and Figure 4 , the hot-cut screen dismantling mechanism 4 includes a guide rail 41 provided on the partition plate 2. A slide table 42 is slidably connected to the guide rail 41. A cutter mounting seat 43 is provided on the slide table 42, and a driving mechanism 44 is provided at the bottom of the slide table 42. Specifically, the hot-cut screen dismantling mechanism 4 ensures the high efficiency and accuracy of dismantling. The guide rail 41, as the guiding device for the movement of the slide table 42, is installed on the partition plate 2 to ensure the stable movement of the slide table 42 in the horizontal direction. The guide rail 41 can bear the weight of the slide table 42 and its components thereon and maintain smooth and unobstructed sliding performance during long-term use. The slide table 42 is the moving platform in the hot-cut screen dismantling mechanism 4. It is slidably connected to the guide rail 41 through a slider, realizing free movement in the horizontal direction. The cutter mounting seat 43 is installed on the slide table 42. The design of the cutter mounting seat 43 takes into account the quick replacement and precise positioning of the cutter to ensure accurate and efficient dismantling of touchscreens of different models and sizes. The driving mechanism 44 is installed at the bottom of the slide table 42 and is connected to the slide table 42 through a transmission device. The driving mechanism 44 uses a high-precision motor or cylinder as the power source and transmits the power to the slide table 42 through transmission components such as gears and belts to drive it to move linearly along the guide rail 41. The driving mechanism 44 is also equipped with a precise control system that can accurately control the moving speed, acceleration, and positioning accuracy of the slide table 42 to ensure that the hot-cut blade 435 can perform cutting according to the preset trajectory and speed. In addition, the hot-cut screen dismantling mechanism 4 may also be equipped with monitoring components such as temperature sensors and pressure sensors to monitor the temperature and cutting force of the hot-cut blade 435 in real time to ensure the safety and stability of the cutting process. At the same time, to deal with emergencies, the mechanism may also be equipped with an emergency stop device that can immediately stop the cutting operation once an abnormal situation is detected, protecting the safety of the equipment and operators. The hot-cut screen dismantling mechanism 4 realizes the efficient and precise dismantling of the touchscreen through the precise cooperation of the guide rail 41, the slide table 42, the cutter mounting seat 43, and the driving mechanism 44, providing strong support for the recycling and reuse of the touchscreen.

[0026] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the cutter mounting base 43 includes a bottom plate 431 mounted on the slide 42. A heating plate 432 is provided on the bottom plate 431, and a fixing plate 433 is provided on the heating plate 432. A hot cutting blade 434 is mounted on one side of the heating plate 432, and a heating rod 435 is installed inside the heating plate 432. Specifically, the cutter mounting base 43 integrates multiple functions of heating, fixing, and cutting, ensuring high efficiency and precision during the disassembly process of the touch screen. The bottom plate 431, as the basic support structure of the cutter mounting base 43, is mounted on the slide 42. The heating plate 432 is a key heating element in the cutter mounting base 43, which is attached to the bottom plate 431 and softens the adhesive on the edge of the touch screen through the heat generated by the heating rod 435. The heating plate 432 is made of a material with high thermal conductivity and high temperature resistance, which can quickly and evenly transfer heat to ensure that the adhesive on the edge of the touch screen reaches an ideal softened state before cutting. At the same time, the heating plate 432 also has excellent insulation performance to prevent current leakage from causing harm to the equipment and operators. The fixing plate 433 is located above the heating plate 432 and is responsible for firmly fixing the hot cutting blade 434 in a predetermined position. The hot cutting blade 434 is the core component for performing the cutting operation, which is made of high-quality alloy steel or cemented carbide materials and has high hardness, high wear resistance, and good thermal conductivity. The edge of the hot cutting blade 434 is specially treated, such as edge grinding or coating treatment, to improve the cutting efficiency and cutting quality. Under the action of the heating plate 432, the hot cutting blade 434 maintains an appropriate temperature, which can effectively soften the material to be cut, reduce the cutting resistance, and at the same time reduce material deformation and burr generation. The heating rod 435 is the heat source inside the heating plate 432, which generates heat through electric current heating and transfers it to the heating plate 432. The heating rod 435 is made of an efficient and energy-saving heating element, which can quickly heat up and maintain a stable temperature output. At the same time, the heating rod 435 is also equipped with a temperature control system, which can monitor the temperature of the heating plate 432 in real time and adjust it as needed to ensure accurate temperature control during the cutting process. The cutter mounting base 43 provides a strong guarantee for the precise and efficient cutting of materials through the coordinated work of components such as the bottom plate 431, heating plate 432, fixing plate 433, hot cutting blade 434, and heating rod 435.

[0027] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the drive mechanism 44 includes a servo motor 441 installed at the bottom of the partition plate 2, and the output end of the servo motor 441 is connected to a screw rod 442, and the screw rod 442 slides through the bottom of the slide 42 to achieve precise movement of the slide 42. Specifically, the drive mechanism 44 serves as the power core of the hot-cut screen removal mechanism 4 to ensure the precise movement of the slide 42. In the hot-cut screen removal equipment, the servo motor 441 is installed at the bottom of the partition plate 2 and is fixed by a sturdy bracket and a shock-absorbing device to reduce the impact of vibration and noise on the motor performance. The servo motor 441 is equipped with a high-performance encoder that can monitor the speed and position of the motor in real time, and feed this information back to the control system to achieve precise closed-loop control. The screw rod 442 is a key transmission element connecting the servo motor 441 and the slide 42. It is made of high-precision, high-wear-resistant materials with precise threads and excellent straightness. One end of the screw rod 442 is tightly connected to the output end of the servo motor 441 through a coupling or other transmission device, ensuring that the power of the servo motor 441 can be efficiently and smoothly transmitted to the screw rod 442. The other end of the screw rod 442 passes through the bottom of the slide 42 and cooperates with the nut or sliding block inside the slide 42, and is converted into a linear movement of the slide 42 through rotational motion. When the servo motor 441 receives the command from the control system, it will perform precise position control according to the preset parameters and algorithms. The servo motor 441 drives the screw rod 442 to rotate, and the thread on the screw rod 442 produces relative motion with the nut or sliding block inside the slide 42, thereby pushing the slide 42 to move accurately in a straight line along the guide rail 41. The drive mechanism 44 realizes the precise movement of the slide 42 through the precise cooperation of the servo motor 441 and the screw rod 442.

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, a rubber gasket 31 is installed at the inner bottom of the fixture 3. There are several ventilation holes on the rubber gasket 31, and an air pump is connected to the bottom of the fixture 3. Specifically, the fixture 3 not only takes into account the stable fixation of the touch screen but also takes into account the detail processing and efficiency improvement during the disassembly process. The rubber gasket 31 installed at the inner bottom of the fixture 3 is not only for providing buffering and protecting the touch screen from possible damage caused by direct contact with hard objects. More importantly, the rubber gasket 31 has good sealing performance and elasticity, can closely fit the bottom of the touch screen, and form a relatively closed space. This helps to maintain the stability of the touch screen during the disassembly process and prevent it from shifting or shaking during the heating and cutting processes. In addition, several ventilation holes are provided on the rubber gasket 31. These ventilation holes allow gas to pass through smoothly. The front side of the touch screen is adsorbed inside the fixture 3 through the air pump, thus protecting the touch screen itself from damage and improving the disassembly efficiency. The air pump connected to the bottom of the fixture 3 is a very important auxiliary device during the disassembly process. The air pump generates negative pressure to suck and fix the front side of the touch screen inside the fixture 3, facilitating the cutting of the hot melt adhesive on the back of the touch screen by the hot cutting blade 434. The rubber gasket 31 at the inner bottom of the fixture 3 and the connected air pump together constitute an efficient, environmentally friendly, and safe disassembly environment. They not only ensure the stability and cleanliness of the touch screen during the disassembly process but also improve the disassembly efficiency and the service life of the equipment.

[0029] Combined with Figure 1 and Figure 2 As shown, the smoke exhaust mechanism 5 includes a smoke exhaust pipe 51 arranged at the top of the cabinet 1. A negative pressure fan is installed on the smoke exhaust pipe 51, and a protective cover 52 is arranged on the outer periphery of the smoke exhaust pipe 51. The air inlet of the negative pressure fan is directly opposite to the upper part of the fixture 3. Specifically, the smoke exhaust mechanism 5 effectively discharges the smoke, harmful gases, and fine particles generated during the disassembly process, ensuring the cleanliness of the operating environment and the health of the operators. The smoke exhaust pipe 51 is arranged at the top of the cabinet 1, fully considering the natural rising law of smoke and hot air, so that they can be smoothly guided into the smoke exhaust pipe. The smoke exhaust pipe 51 is made of high-temperature resistant and corrosion-resistant materials to ensure stable operation in an environment of long-term high temperature and corrosive gases. Its internal design has a smooth flow channel to reduce air flow resistance and improve the smoke exhaust efficiency. The air inlet of the negative pressure fan is directly opposite to the upper part of the fixture 3 to ensure that the smoke and harmful gases generated during the disassembly process can be directly and efficiently sucked away. A protective cover 52 is arranged on the outer periphery of the smoke exhaust pipe 51, which not only enhances the overall aesthetics of the smoke exhaust mechanism 5 but more importantly provides multiple protections. The protective cover 52 is made of strong and durable materials, which can effectively prevent accidental collisions and damages of external objects to the smoke exhaust pipe 51 and the negative pressure fan. The protective cover 52 also has a certain heat insulation effect, which can reduce the surface temperature of the smoke exhaust pipe and prevent safety accidents such as scalding.

[0030] Combined withFigure 1 and Figure 2 As shown in Figure 2 , infrared sensors 6 are provided on both sides inside the cabinet body 1, and an induction switch 7 is provided on one side of the cabinet body 1. Specifically, the infrared sensors 6 provided on both sides inside the cabinet body 1 are an important part of the intelligent operation of the device. These infrared sensors 6 adopt advanced infrared detection technology and can real-time sense the spatial state inside the cabinet body 1 and whether there are objects (such as the hands or tools of the operator) entering the dangerous area. The precise layout of the infrared sensors 6 ensures dead-angle-free monitoring and effectively prevents accidental touches or misoperations that may occur during the disassembly process. When it senses that someone or an object approaches dangerous components such as the hot cutting blade 434 and the heating plate 432, the infrared sensor 6 will immediately trigger a safety mechanism, such as pausing the operation of the device or emitting an alarm sound, to remind the operator to pay attention to safety. The induction switch 7 provided on one side of the cabinet body 1 provides a more convenient and user-friendly operation method for the operator. When the operator needs to take out or put in the touch screen, pressing the induction switch 7 can pause the device, and at this time the infrared sensor 6 will also be turned off, thus preventing the operator's hand from touching the working device and causing damage. The settings of the infrared sensor 6 and the induction switch 7 in the cabinet body 1 not only improve the safety and convenience of the device but also reflect the pursuit of intelligent and user-friendly design in modern touch screen disassembly devices.

[0031] Combined with Figure 1 and Figure 2As shown in the figure, a control system 8 is provided on one side inside the cabinet body 1. Specifically, the control system 8 provided on one side inside the cabinet body 1 integrates advanced control technologies, data processing capabilities, and user interfaces, ensuring the efficient and stable operation of the equipment and a convenient operation experience. The core of the control system 8 is a high-performance control unit, which uses an advanced microprocessor or an industrial-grade PLC (programmable logic controller) and has powerful data processing capabilities and real-time control capabilities. This control unit is responsible for receiving signals from the infrared sensor 6, the induction switch 7, and other sensors (such as temperature sensors, pressure sensors, etc.), analyzing and processing them according to preset programs and algorithms, and sending out corresponding control instructions to drive actuators such as motors, heaters, and negative pressure fans to work. The control system 8 has a high level of intelligent management and can adjust working parameters according to real-time data during the disassembly process to optimize the disassembly process. For example, the control system 8 can automatically adjust the heating temperature and time according to the characteristics of the touch screen material, thickness, etc., to ensure the cutting effect while avoiding overheating damage; or automatically pause or start the equipment according to the actions of the operator monitored by the infrared sensor 6 to improve operation safety. To facilitate the use of the operator, the control system 8 is also equipped with an intuitive and easy-to-use user interface. This interface is presented through a touch screen or an LED display screen and can display important information such as the working status of the equipment, the disassembly progress, and fault information. The operator can operate through buttons, knobs, or the touch screen on the interface to easily complete tasks such as starting, stopping, and parameter setting of the equipment. In addition, some advanced control systems also support remote control and monitoring functions, enabling the operator to grasp the operation status of the equipment in real time at different locations. Considering the possible safety risks during the disassembly process, the control system 8 also integrates a perfect safety protection mechanism. These mechanisms include but are not limited to: emergency stop buttons, overload protection, short-circuit protection, over-temperature protection, etc. Once the equipment detects an abnormal situation or receives an emergency stop signal, the control system will immediately cut off the power supply or stop the work of relevant actuators to prevent the situation from expanding and ensure the safety of the operator.
