[0002] In modern industrial production, hot melt machines, as specialized equipment for welding thermoplastic parts, are widely used in various industries such as electronics, automobiles, and home appliances due to their efficient and reliable bonding performance. Traditional button hot melt processes mainly rely on manual operation, requiring operators to hold hot melt tools and heat and weld the button components one by one. This manual method is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale industrial production.
[0003] During manual hot-melt welding, variations in operator skill levels and habits can easily lead to unstable control of temperature, pressure, and time, resulting in inconsistent welding quality of button components and defects such as incomplete soldering and over-melting, affecting product consistency and reliability. Furthermore, manual operation requires operators to maintain high concentration for extended periods, leading to high workload, fatigue, and increased production safety hazards. In addition, the manual hot-melt process lacks effective automated control and quality inspection methods, making real-time monitoring and adjustment of the production process difficult and hindering product quality traceability and improvement. Therefore, a button hot-melt machine is proposed to address these issues. Utility Model Content

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 In this embodiment, a button hot melt machine is provided. The frame 300 is the supporting structure of the entire button hot melt machine and is composed of the frame control room 301, the machine body 302, the top plate 303, and the frame cylinder 304, etc.
[0022] The frame control room 301 is integrally formed with the machine body 302, which ensures the overall strength and stability of the frame and provides reliable support for the installation and operation of the internal components;
[0023] The machine body 302 is located on top of the machine frame control room 301, and its internal space is used to install components such as the lower mold device 200 and the forward push device 201.
[0024] The top plate 303 is set in the middle of the top hollow of the machine body 302. The frame cylinder 304 is installed on the top of the top plate 303, and its output end extends to the bottom of the top plate 303. It is fixedly connected to the upper fixing plate 101 in the upper mold device 100 through the mounting plate.
[0025] The function of the frame cylinder 304 is to provide power to push the upper fixed plate 101 down, so that the component pressing device 102 in the upper mold device 100 can press the button component to be heat-melted, ensuring the stability of the component position during the heat-melting process.
[0026] Upper mold device:
[0027] The upper mold device 100 mainly includes an upper fixing plate 101 and a component pressing device 102;
[0028] The upper fixed plate 101 is fixedly connected to the output end of the frame cylinder 304 through the mounting plate, and moves up and down under the drive of the frame cylinder 304;
[0029] The component pressing device 102 is installed at the bottom of the upper fixed plate 101. Its function is to press the button component during the hot melting process to prevent the component from being displaced or deformed under the action of the hot melting head 206, and to ensure the hot melting quality.
[0030] The component pressing device 102 can be designed and adjusted according to different button component shapes and sizes to meet diverse production needs.
[0031] Lower mold device:
[0032] The lower mold device 200 is the core working component of the button hot melt machine, including a fixed base 203, a fixed base plate 204, a movable plate 205, a hot melt head 206, a heat insulation plate 207, and a hot melt cylinder 202, etc.
[0033] The fixed base 203 is used to place the button products to be heat-melted. Its surface is designed according to the shape of the product to ensure that the product can be accurately positioned.
[0034] The fixed base plate 204 is set on top of the L-shaped connecting plate 500. The L-shaped connecting plate 500 is installed on top of the frame control room 301 and located inside the machine body 302, providing support for the fixed base plate 204.
[0035] The hot melt head 206 integrates a heating element and a temperature sensing wire. The heating element generates the heat required for hot melting, and the temperature sensing wire monitors the temperature of the hot melt head in real time and feeds the temperature signal back to the control system so that the control system can adjust the heating power of the heating element to achieve precise control of the hot melting temperature.
[0036] The hot melt head 206 and the fixed base 203 are coaxially aligned to form an integrated hot melt support structure;
[0037] The hot melt head 206 can be detachably installed between the heat insulation plate 207 and the fixed base plate 204 for easy replacement and maintenance;
[0038] The heat insulation plate 207 is set at the top of the output end of the two hot melt cylinders 202 at both ends. Its function is to isolate the heat generated by the hot melt head 206 and prevent the heat from being transferred to the hot melt cylinders 202 and other components, thus affecting their normal operation.
[0039] The function of the hot melt cylinder 202 is to provide power to push the heat insulation plate 207 and the hot melt head 206 up or down, so as to achieve contact and separation between the hot melt head and the button component.
[0040] Forward pushing device:
[0041] The forward thrust device 201 is located inside the body 302 and is used to push one of the hot melt cylinders 202 to move horizontally.
[0042] The forward pushing device 201 includes a forward pushing cylinder 2011, an L-shaped slide plate 2012, a motor plate 2013, and a slide rail 2014.
[0043] The motor plate 2013 is located on the top of the frame control room 301, and the forward thrust cylinder 2011 is fixedly installed on the side of the motor plate 2013 to provide power for horizontal thrust.
[0044] The slide rail 2014 is set on the top of the motor plate 2013. The L-shaped slide plate 2012 is movably set on the top of the motor plate 2013 via the slide rail 2014. The bottom of the slide plate 2012 is provided with a groove that fits the slide rail 2014 with a clearance, so as to ensure that the L-shaped slide plate 2012 can slide smoothly on the slide rail 2014.
[0045] The output end of the front push cylinder 2011 is connected to the L-shaped slide plate 2012. When it is necessary to push the hot melt cylinder 202 to move horizontally, the front push cylinder 2011 is activated, and the hot melt cylinder 202 is driven to move along the slide rail 2014 through the L-shaped slide plate 2012, so as to adjust the position of the hot melt cylinder 202 to adapt to the hot melt requirements of button products of different sizes and shapes.
[0046] The working principle of the above embodiments is as follows:
[0047] The operator first places the button product to be heat-melted on the fixed base 203, ensuring accurate positioning through the positioning structure of the fixed base 203. Then, the operator presses the start switch with both hands, and the frame cylinder 304 starts working. Its output end pushes the upper fixed plate 101 and the component pressing device 102 downward. When the component pressing device 102 contacts the button product, it presses the product firmly and fixes it, preventing displacement during the subsequent heat-melting process.
[0048] Next, the forward-pushing cylinder 2011 is activated, pushing the L-shaped slide plate 2012 forward along the slide rail 2014. The L-shaped slide plate 2012 drives the connected hot melt cylinder 202 and hot melt head 206 to move horizontally, aligning the hot melt head 206 with the part to be hot-melted. Simultaneously, the hot melt cylinder 202 is activated, causing the hot melt head 206 to rise. The heating element integrated in the hot melt head 206 has been preheated to the set temperature. When the hot melt head 206 contacts the button component, the heat generated by the heating element melts the plastic on the surface of the component, achieving a hot melt connection. During the hot melt process, the temperature sensing wire monitors the temperature of the hot melt head 206 in real time and feeds the temperature signal back to the control system. The control system automatically adjusts the heating power of the heating element based on the temperature feedback signal to ensure that the hot melt temperature remains within the set range, guaranteeing the stability of the hot melt quality.
[0049] After the hot-melt process is complete, the hot-melt cylinder 202 lowers the hot-melt head 206 back to its initial position. The forward-pushing cylinder 2011 then retracts the hot-melt cylinder 202 and the hot-melt head 206 horizontally, detaching them from the button product. Subsequently, the frame cylinder 304 raises the upper mold device 100, and the component pressing device 102 releases the button product. The operator can then remove the hot-melt-completed product, completing one work cycle. The entire process is highly automated, with all components working in tandem, achieving efficient and high-quality hot-melt production of button products.
