Description

Technical Field

[0001] This invention belongs to the field of building materials and their automated production technology. It relates to processes such as feeding, laser adhesive removal, solder paste spraying, positioning copper pillars, laser welding, AB insulating glue filling, glue cap assembly, and visual inspection of nanofilm-laminated heating plate materials. It can automatically perform processes such as laser adhesive removal, welding, glue filling, assembly, and inspection of nanofilm heating plates, enabling accurate and rapid mass production of nanofilm heating plates and improving work efficiency. Background Technology

[0002] Currently, centralized heating is widely used for winter heating in northern regions. This involves transporting heat-conducting media, such as water, through pipes to users' heating devices, which then distribute the heat to their homes. This method requires extensive preparatory work, such as laying numerous pipes and installing heating equipment in homes, necessitating significant investment of manpower and resources. The installation process is complex and costly. Furthermore, existing heating methods use boilers to heat the heat transfer medium, which require fuels like coal, and the combustion of these fuels generates pollution. While various geothermal panels are available on the market, their complex manufacturing processes and high production and installation costs prevent widespread adoption. Summary of the Invention

[0003] This invention primarily provides a low-cost, simple-structured, and easy-to-use nanofilm heating panel and its automated production line process. The product serves as an inexpensive and readily available heating building material; it only requires pre-installing electrical wiring on each floor panel during renovation, reducing renovation time and environmental pollution. The designed automated production line process further reduces manufacturing costs and improves production efficiency. During production, the automated production line automatically feeds the nanofilm heating panel material, laser-removes the nanofilm from the holes, applies solder paste, positions the conductive copper pillars and performs laser welding, performs visual inspection, and applies AB insulating adhesive, offering the advantage of rapid production of nanofilm heating panels.

[0004] The above-mentioned objective of the present invention is achieved through the following technical solution:

[0005] A nanofilm heating plate and its automated production line process are disclosed. The nanofilm heating plate includes a heating plate base plate, a heating plate face plate, a nanofilm, copper foil, conductive copper pillars, and insulating caps. The automated production line consists of a feeding device, a laser adhesive removal device, a solder paste spraying device, a laser welding device, an AB glue filling device, a cap assembly device, five sets of vision inspection devices, and a discharging device. Each device operates as an independent machine in a series assembly line. The five sets of vision inspection devices include a surface CCD vision inspection device, a solder paste CCD vision inspection device, a soldering CCD vision inspection device, an adhesive filling CCD vision inspection device, and an assembly CCD vision inspection device. Each vision inspection device is equipped with a defective product storage area. The entire system can complete the production processes of feeding, laser adhesive removal, solder paste spraying, copper pillar positioning, laser welding, insulating glue filling, cap assembly, vision inspection, and discharging of the nanofilm heating plate material.

[0006] To implement the above technical solution, the nanofilm heating plate material is manually placed onto the feeding device, and then the nanofilm heating plate is transferred to the laser adhesive removal device.

[0007] Furthermore, the laser adhesive removal device is assembled from four CO2 laser cutting machines. When the nanofilm heating plate moves directly under the adhesive removal device, the four CO2 laser cutting machines simultaneously perform laser scanning on the adhesive removal positioning hole, vaporizing and removing the nanofilm from the copper foil surface to complete the adhesive removal process, and then convey it to the surface CCD visual inspection device.

[0008] Furthermore, the surface CCD visual inspection device consists of four camera lenses that take pictures and inspect the incoming nanofilm heating plate to determine the adhesive removal effect and calculate the position of the adhesive removal positioning hole. Then, based on the inspection results, the material is transferred to the solder paste spraying device or the defective product storage area.

[0009] Furthermore, the solder paste spraying device consists of four solder paste spraying valves. When the nano-film heating plate arrives below, the four solder paste spraying valves simultaneously spray solder paste directly above the four glue removal positioning holes, and then the board material is conveyed to the solder paste CCD vision inspection device.

[0010] Furthermore, the solder paste CCD vision inspection device consists of four camera lenses to detect the effect of solder paste spraying in the solder paste positioning hole, take pictures above it for inspection, and good products continue to move to the laser welding device, while defective products will be moved to the defective product storage area.

[0011] Furthermore, the laser welding device is equipped with four sets of fiber laser welding machines, and four conductive copper column vibratory feeders and clamping robots are installed on both sides. When the nanofilm heating plate moves to the laser welding station, the four sets of conductive copper column clamping robots move to pick up the material, clamping the conductive copper columns from the outlets of the four conductive copper column vibratory feeders and placing them into the four welding positioning holes. After the material is placed, they retract. Then, the four sets of fiber laser welding machines are started to weld the four conductive copper columns onto the copper foil in the welding positioning holes from a distance.

[0012] Furthermore, the nanofilm heating plate is transmitted to a welding CCD vision inspection device to photograph and inspect the welding process.

[0013] Implementing the above technical solution, the welding CCD visual inspection device consists of 4 camera lenses, which simultaneously photograph and inspect the welding positioning holes of the 4 conductive copper pillars, and determine the movement of the nano-film heating plate to the potting device or the defective product storage area based on the results.

[0014] Furthermore, the glue-filling device is assembled from four sets of AB glue-filling valves. When the nanofilm heating plate is conveyed directly below the AB glue-filling valves, the control system simultaneously opens the AB glue-filling valves and performs the AB glue-filling process by setting a circular path with the center of the welding positioning hole. After the AB insulating glue is filled, the AB glue-filling valves are closed, and the nanofilm heating plate is continued to be conveyed to the glue-filling CCD vision inspection device for glue quantity detection.

[0015] Furthermore, the cap assembly device consists of four sets of three-axis assembly robots. Four insulating cap vibratory feeders and four sets of assembly robots are installed on both sides. When the nanofilm heating plate material moves to the assembly station, the four sets of assembly robots move simultaneously to pick up the material, sucking it from the outlet of the four insulating cap vibratory feeders, and then moving it above the glue positioning hole. The insulating cap is pressed into the hole and assembled with the conductive copper pillar. After completing the assembly, it returns to the outlet of the insulating cap vibratory feeder and is then conveyed to the assembly CCD vision inspection device to take pictures and check the cap assembly status. The material is then conveyed to the unloading device or the defective product storage area.

[0016] Implementing the above technical solution, when the nanofilm heating plate moves to the assembly station, the control system sends a signal to each of the four assembly robots. Their moving suction nozzles pick up and transfer the insulating caps to directly above the conductive copper pillar welding point, then press them down to the center of the nanofilm heating plate's material hole, assembling the insulating caps onto the conductive copper pillar. If there are defective products in each defective product storage area, the data will be provided to the control system. If more than 20 defective products are stored in the same storage area, the control system will pause the entire production line operation. After the defective products are manually removed, automated production will resume. Attached Figure Description

[0024] The specific embodiments of this application are as follows:

[0025] like Figure 1 The aforementioned nanofilm heating plate and its automated production line process comprises a feeding device 1, a laser adhesive removal device 2, a solder paste spraying device 3, a laser welding device 4, an AB glue filling device 5, a glue cap assembly device 6, five sets of vision inspection devices, and an unloading device 7. Each device operates as an independent machine in a series conveyor system. The five sets of vision inspection devices include a surface CCD vision inspection device 21, a solder paste CCD vision inspection device 31, a welding CCD vision inspection device 41, an adhesive filling CCD vision inspection device 51, and an assembly CCD vision inspection device 61. Each vision inspection device is equipped with a defective product storage area 9.

[0026] As shown in the figure Figure 2 and Figure 3 The nanofilm heating plate 100 is composed of a heating plate base plate 101, a heating plate panel 102, a nanofilm 103, two copper foils 104, four conductive copper pillars 105, and four insulating caps 106; wherein the two layers of nanofilm 103 bond the two parallel copper foils 104 together, and then the heating plate base plate 101 and the heating plate panel 102 are bonded together.

[0027] like Figure 1 and Figure 4 As shown in the figure, the nanofilm heating plate 100 is placed at the feeding device 1 and conveyed to the area directly below the laser adhesive removal device 2. Four CO2 laser cutters 201 simultaneously scan the adhesive removal positioning holes 107, removing the nanofilm 103 from the surface of the copper foil 104 through high-temperature vaporization. The plate is then conveyed to the surface CCD visual inspection device 21, where four cameras 8 take pictures for inspection. The control system 10 calibrates the adhesive removal positioning holes 107 based on the adhesive removal effect and determines whether the incoming material should be conveyed to the solder paste spraying device 3 or the defective product storage area 9. When a good nanofilm heating plate 100 is conveyed to the area below the solder paste spraying device 3, four solder paste spraying valves 301 simultaneously spray solder paste above the four adhesive removal positioning holes 107. After completion, the plate is further conveyed to the solder paste CCD visual inspection device 31 for inspection.

[0028] like Figure 1 and Figure 5 As shown in the figure, the nanofilm heating plate 100 is conveyed to the laser welding device 4 and fixed directly below the fiber laser welding machine 401. Four clamping robots 40 respectively pick up the conductive copper pillars 105 from the outlets of the four conductive copper pillar vibrating plates 42 on both sides, place them into the welding positioning holes 108, and then withdraw. At this time, the four fiber laser welding machines 401 start simultaneously, welding the conductive copper pillars 105 onto the copper foil 104, and then transmitting them to the welding CCD vision inspection device 41 for inspection. When the good nanofilm heating plate 100 is conveyed to the AB glue filling device 5, the four AB glue filling valves 501 simultaneously fill AB glue directly above the four welding positioning holes 108. After completion, it continues to be conveyed to the glue filling CCD vision inspection device 51 for inspection.

[0029] like Figure 1 and Figure 6As shown in the figure, the nanofilm heating plate 100 is conveyed to the cap assembly device 6 and fixed at the center of four assembly robots 60. After fixing, the four assembly robots 60 are activated to pick up the insulating caps 106 from the discharge ports of the four insulating cap vibrating plates 62 on both sides, place them into the welding positioning holes 108, and then remove them to press the insulating caps 106 onto the conductive copper pillars 105 and fit them tightly. Then, they are transferred to the assembly CCD vision inspection device 61 for inspection. The four camera lenses take pictures of the assembly positioning holes 109 for inspection. The control system 10 determines whether the nanofilm heating plate 100 flows into the discharge device 7 or the defective product storage area 9, thus completing the entire production process while ensuring quality.
