Description

[0002] The heating film is a thin film that can generate heat when electricity is applied. It is a planar heating element composed of an electrical insulating material and a heating resistor material encapsulated therein. The advantages of the heating film are no open flame heating, surface heating, and low thermal resistance.

[0003] In the prior art, laser die-cutting is usually used to process the heating film. Laser die-cutting is a thermal cutting method that replaces the die-cutting steel knife with a focused laser beam. The incisions and connection points of the product are made by the continuity and disconnection of pulses for cutting. However, the electrical box and cooling device of the existing laser die-cutting machine are directly arranged on the laser base, that is, on the integrally movable structure closest to the laser. Although this can reduce the complexity of the structure and pipelines, it will cause the laser base to be too heavy. Since the setting method between the sliding cross bar and the track of the laser base needs to bear the torque from the laser base, it is necessary to invest more fixing mechanisms on the sliding cross bar. The increase in the laser base is also not conducive to the utilization of space.

DETAILED DESCRIPTION

[0023] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0024] Please refer to Figure 1-4 The embodiment of the present invention provides a laser-based heating film rapid prototyping device, which is suitable for factories that laser cut heating films or for laboratory scenes after miniaturization, and includes a sliding crossbar 200 and a laser seat 301. The laser seat 301 can slide left and right on the sliding crossbar 200. A laser cutting device 302 is installed at the front end of the laser seat 301. The laser cutting device 302 includes a laser 311. A protective cover 313 is fixed to the outside of the laser 311. A fixed cover 309 is fixed to the upper side of the protective cover 313. The fixed cover 309 is penetrated by a water outlet hose 310 and a water inlet hose 314. The water outlet hose 310 and the protective cover 313 are connected to each other. 13 is internally connected, the water inlet hose 314 is connected to the interior of the protective cover 313, the protective cover 313 is also provided with a spiral deflector 312, the sliding cross bar 200 includes a cooling box 202 and an electrical box 205, the electrical box 205 is arranged in the cooling box 202, the electrical box 205 is electrically connected to the laser 311, the cooling box 202 is connected to the water outlet hose 310, and the cooling box 202 is also connected to the water inlet hose 314, so that the cooling device and the main body of the electrical box 205 are arranged in the sliding cross bar 200 instead of on the laser base 301, the weight of the laser base 301 is reduced, and better space utilization is achieved.

[0025] In this embodiment, by arranging the cooling box 202 and the electrical box 205 in the sliding cross bar 200, the weight of the laser seat 301 is concentrated on the more stable sliding cross bar 200, thereby reducing the weight of the laser seat 301, and by integrating these components inside the sliding cross bar 200, the occupied space of the laser seat 301 is effectively utilized, so as to achieve the effect of reducing the weight of the laser seat 301 and reducing its occupied space. Specifically, a laser cutting device 302 is installed at the front end of the laser seat 301, and the laser cutting device 302 includes a laser 311, a protective cover 313 is fixed outside the laser 311, and a fixed cover 309 is installed above the protective cover 313. The fixed cover 309 is penetrated by a water outlet hose 310 and a water inlet hose 314, the water outlet hose 310 is connected to the inside of the protective cover 313, and the water inlet hose 314 is connected to the inside of the protective cover 313. A spiral deflector 312 is provided in the protective cover 313 to optimize the flow of coolant. By arranging the electrical box 205 and the cooling box 202 in the sliding cross bar 200, the weight of the laser base 301 is reduced. At the same time, by reasonably arranging the components, the space utilization of the laser base 301 is optimized, thereby solving the technical problem that the laser base 301 is too heavy and occupies too much space.

[0026] It should be noted that the cooling water selected in this embodiment is deionized water; this device relies on a water pump arranged in the outer shell 308 to pump water to the water outlet device, the sliding cross bar 200 is movably arranged on the sliding seat 100, and the laser seat 301 is movably arranged on the sliding cross bar 200. It can be understood that the two structures can be connected by a rail connection or other connection methods.

[0027] In one embodiment, the laser cutting device 302 includes a housing 308, a laser 311 is disposed at the lower portion of the housing 308, a protective cover 313 is cylindrical, and a fixed cover 309 is fixed to the lower portion of the housing 308 by bolts. Figure 2 The outer shell 308 is a rectangular parallelepiped as a whole, and a part protrudes from the lower part of the outer shell 308. The protruding part is used to set a fixed cover 309, and the fixed cover 309 is fixed in this protruding part by bolts. The protective cover 313 is set to a circular shape, so that the protective cover 313 and the fixed cover 309 can be better matched and fixed. At the same time, the spiral structure of the deflector 312 and the protective cover 313 are more matched. The fixed cover 309 is made of flexible rubber material. Therefore, when the bolts squeeze the fixed cover 309 downward, the fixed cover 309 will generate an inward pressure on the water outlet hose 310 and the water inlet hose 314 that are penetrated by itself, thereby better achieving the sealing effect.

[0028] Furthermore, the deflector 312 is fixed to the inner wall of the protective cover 313. Specifically, the deflector 312 adopts a spiral design and is directly fixed to the inner wall surface of the protective cover 313 by bolts or other suitable fixing methods. The spiral structure of the deflector 312 extends along the inner wall of the protective cover 313 to form a continuous guide channel, so that the cooling water can flow along the spiral path when flowing into the protective cover 313.

[0029] Therefore, when the cooling water enters the protective cover 313 through the water inlet hose 314, the spiral shape of the deflector 312 guides the water flow to the inner wall of the protective cover 313, and makes the water flow evenly surround the entire protective cover 313, thereby improving the cooling effect. At the same time, the spiral guide structure increases the contact area between the cooling water and the inner surface of the protective cover 313, thereby improving the heat exchange efficiency, effectively reducing the operating temperature of the laser 311, and ensuring that the laser 311 operates stably during long-term use; by fixing the deflector 312 on the inner wall of the protective cover 313, the cooling water can maintain a more uniform flow rate and distribution during the flow process, avoiding uneven cooling and causing local overheating of the laser 311.

[0030] In one embodiment, the end of the water inlet hose 314 is inserted through the deflector 312 and is arranged at the bottom of the deflector 312, and the end of the water outlet hose 310 is arranged at the top of the deflector 312. Specifically, the end of the water outlet hose 310 is inserted through the top of the deflector 312 to ensure that the cooling water can flow evenly along the spiral path after entering the deflector 312 from the top, gradually flow downward to the bottom, and be discharged through the water outlet hose 310. This design makes the flow of cooling water smoother and the flow rate uniform, effectively avoiding uneven cooling caused by too fast or too slow water flow. The water inlet hose 314 and the water outlet hose 310 are respectively located at the bottom and top of the deflector 312, ensuring that the cooling water can form a circulation flow in the deflector 312. The process of water flow from top to bottom strengthens the heat exchange process of the coolant, avoids the situation where the water flow is stagnant or uneven in a certain part, and thus achieves an efficient heat dissipation effect.

[0031] Furthermore, a sliding drag chain 306 is provided on the upper part of the cooling box 202, and a pipe is provided inside the sliding drag chain 306, one end of the pipe is connected to the cooling box 202, and the other end of the pipe is connected to the water inlet hose 314 and the water outlet hose 310. Specifically, the design of the sliding drag chain 306 enables the pipe to move flexibly within a fixed track, which not only avoids the waste of space caused by the random placement of the pipe in the external space, but also reduces the interference between the pipe and other mechanical parts, making the overall device more concise and compact, and also enables the device to withstand a higher movement frequency and maintain a good cooling effect.

[0032] Furthermore, an elevated frame 304 is provided on the laser base 301, and the water inlet hose 314 and the water outlet hose 310 are both installed on the elevated frame 304. A quick-plug interface 305 is provided on the elevated frame 304, and a quick-plug connector 307 is provided at one end of the sliding drag chain 306. The quick-plug connector 307 and the quick-plug interface 305 can be fixedly connected. Specifically, the raising frame 304 is installed on the upper part of the laser base 301, and plays the role of supporting and lifting the water inlet hose 314 and the water outlet hose 310. The water inlet hose 314 and the water outlet hose 310 are respectively installed on the raising frame 304 through fixing parts, so as to ensure that the hoses can be stably connected to the cooling system of the laser 311; the quick-plug interface 305 on the raising frame 304 is connected with the quick-plug connector 307 at one end of the sliding drag chain 306. The design of the quick-plug interface 305 and the connector makes the connection between the water inlet hose 314 and the water outlet hose 310 more convenient and quick, and no tools are required during installation and disassembly; at the same time, this structure also enables it to better cooperate with the sliding drag chain 306, and further withstand higher movement frequencies.

[0033] In one embodiment, a plurality of heat dissipation baffles 203 are arranged in the cooling box 202, and the heat dissipation baffles 203 are arranged in a staggered manner between adjacent heat dissipation baffles 203, and the heat dissipation baffles 203 are arranged at the left and right ends of the cooling box 202, and the electrical box 205 is arranged in the middle of the cooling box 202. Specifically, the staggered heat dissipation baffles 203 promote the cooling water circulation inside the cooling box 202 by optimizing the cooling water flow path, so that the heat generated by the electrical box 205 and the laser 311 is effectively guided to the heat dissipation area, and at the same time, the structure of the heat dissipation baffles 203 can prevent the internal cooling water from causing a slight displacement or vibration to the device body due to the inertia generated by the large movement of the sliding cross bar 200, so as to make the structure more stable.

[0034] Furthermore, the rear of the cooling box 202 is provided with heat dissipation fins 204, and the adjacent heat dissipation fins 204 are arranged in a staggered manner, and the upper part of the heat dissipation fins 204 is provided with an air cooling device 201. Specifically, the heat dissipation fins 204 are connected to the rear of the cooling box 202 by welding, bolts or clamping devices; the upper part of the heat dissipation fins 204 is provided with an air cooling device 201, and the air cooling device 201 is composed of a fan or other air circulation device, which is connected to the heat dissipation fins 204 through a bracket or a fixing frame or directly installed on the cooling box 202; the staggered heat dissipation fins 204 provide more surface area, so that heat can be transferred from the inside of the cooling box 202 to the outside faster, and the air cooling device 201 accelerates the air flow by continuously blowing air, thereby helping to take away the heat accumulated on the heat dissipation fins 204, and optimizes the air flow and heat conduction, so that the system can complete heat dissipation in a more energy-saving manner.

[0035] Furthermore, the heat sink fins 204 are disposed on the left and right of the cooling box 202, and the air cooling device 201 is disposed on the left and right of the cooling box 202. This design eliminates the need for more cooling fans in the middle of the cooling box 202, and allows the flow characteristics of the liquid itself to form a cooling effect on the middle, thereby reducing the number of fans and achieving a more energy-saving effect.

[0036] Optionally, a sensor device 303 is also provided on the laser base 301, and the sensor device 303 is used to receive image signals. Specifically, the laser base 301 is provided with a sensor device 303, and the sensor device 303 is fixed to the laser base 301 by a bracket, a clamp or a bolt. The sensor device 303 includes an image acquisition device, such as a camera or a photoelectric sensor, and its structure is compact and firmly fixed to ensure that the sensor can work stably and accurately capture image signals. The sensor device 303 is mainly used to receive and capture image signals in real time during the laser cutting process, and help monitor the accuracy and stability of the laser cutting. Through image acquisition, the sensor can identify the cutting position, cutting quality or abnormal conditions, and feed back the data to the control system, so that the system can ensure that each cutting achieves the expected effect and reduces errors.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
