Description

Technical Field

[0001] The present invention relates to a welding apparatus, and more particularly to a novel welding apparatus for door and window processing. Background Technology

[0002] Welding is a common metal processing technique that enables the stable connection and combination of different metal parts. Modern welding uses a variety of energy sources, including gas flame, electric arc, laser, electron beam, friction, and ultrasound. As welding techniques become more sophisticated, the strength of welds between structures is enhanced. Welding is also required in the production of some doors and windows.

[0003] Currently, there are two welding methods in the welding process of plastic doors and windows: seamless welding and seam welding. Seamless welding is mainly used for welding colored doors and windows, while seam welding is mainly used for welding ordinary doors and windows. Regardless of the welding method, a four-corner welding machine is required.

[0004] For example, the specification of patent publication number CN107639842B discloses a four-corner welding machine head and welding method for welding plastic doors and windows. The machine head base includes a clamping mechanism, a milling cutter mechanism, a heating mechanism, a pressure plate mechanism, and a positioning mechanism mounted on the machine head base. The clamping mechanism includes an upper clamp and a lower clamp arranged vertically. The lower clamp has a tooling push plate, and the upper clamp is connected to a clamping cylinder. The upper and lower clamps cooperate to clamp adjacent profiles. The milling cutter mechanism mills the end face of the profile. The heating plate of the heating mechanism heats and melts the end face of the profile. The pressure plate mechanism squeezes the weld seam to prevent weld beads. This four-corner welding machine head and welding method can effectively avoid the generation of weld beads on the surface, inner corners, and outer corners of the profile, solving the aesthetic problem of the profile and having lower requirements for profile dimensions, thus greatly reducing production costs.

[0005] Based on the above search and combined with the existing technology, it was found that the welding device for door and window processing disclosed above generates a lot of heat when welding the frame strips of doors and windows. When the heat is too high, it is easy to cause deformation of the weld and reduce the welding quality. In addition, the heating plate generally cools naturally after heating the frame strips, resulting in heat waste. Therefore, a new type of welding device for door and window processing is proposed to improve the above problems. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when welding the frame strips of doors and windows in the prior art, the welding point has a high heat, and the excessive heat can easily cause deformation of the welding point, reducing the welding quality; in addition, the heating plate generally cools naturally after heating the frame strips, resulting in heat waste.

[0007] To address the above problems, the present invention provides a novel welding apparatus for door and window processing, comprising:

[0008] The welding platform has a main positioning mechanism and a side positioning mechanism installed at its upper end. The two side positioning mechanisms are located on both sides of the main positioning mechanism and are set at a 90-degree angle to the main positioning mechanism.

[0009] Heating mechanism: Two heating mechanisms are respectively installed on the side of the two side positioning mechanisms near the main positioning mechanism. The heating mechanism includes a lifting push rod and a heating component.

[0010] The lifting push rod is mounted on the side positioning mechanism, and the heating component includes a mounting base and a heating plate;

[0011] The mounting base is installed at the output end of the lifting push rod. The mounting base is vertically installed at the lower middle part of the mounting base, and the heating plate is set at a 45-degree angle to the main positioning mechanism.

[0012] Multiple thermocouples are fixed at equal intervals at the lower end of the mounting base. Multiple vertical tube grooves are provided at the upper end of the heating plate along its length. Multiple thermocouples are inserted into the inner side of multiple tube grooves in a corresponding manner. Thermocouples are used to monitor the temperature change of the heating plate in real time. When the heat generated during the welding process exceeds the heat dissipation capacity of the heating plate itself, thermocouples convert this excess heat into electrical energy.

[0013] Thermoelectric power generation module is mounted on the mounting base and connected to thermocouple one. The thermoelectric power generation module collects the electrical energy generated by thermocouple one and converts it into a higher voltage output.

[0014] In the aforementioned new welding device for door and window processing, a thermocouple is installed to monitor the temperature change of the heating plate in real time. When the heat generated during the welding process exceeds the heat dissipation capacity of the heating plate itself, the thermocouple converts the excess heat into electrical energy, preventing the heating plate from overheating and causing deformation of the welded joint of the frame strip, thereby improving the welding quality. Furthermore, the thermoelectric power generation module collects the electrical energy generated by the thermocouple and converts it into a higher voltage output, realizing the effective utilization of energy.

[0015] As a further supplement to this application, the main positioning mechanism includes a limit push seat, a welded push rod, and a clamping assembly;

[0020] The lifting push rod is installed on the side end of the limit stop near the limit push seat.

[0021] As a further supplement to this application, a cooling box is installed at the upper end of the mounting base, and coolant is contained inside the cooling box. The upper end of thermocouple one penetrates the mounting base and extends to the inside of the cooling box. The coolant can further increase the temperature difference between the two ends of thermocouple one, thereby improving the heat-to-electrical energy conversion rate.

[0022] As a further supplement to this application, the lower end of the mounting base is equipped with a liquid inlet pipe and a liquid outlet pipe that are connected to each other. Both the liquid inlet pipe and the liquid outlet pipe are connected to the inside of the cooling box. A circulation pump is installed on the liquid inlet pipe and a check valve is installed on the liquid outlet pipe.

[0023] The heating plate is equipped with a tube groove that matches the inlet and outlet pipes; the cooling liquid in the cooling tank can be used to circulate and cool the heating plate, further enhancing the heat dissipation effect of the heating plate.

[0024] As a further supplement to this application, a dispersion tube assembly is provided inside the cooling box, the dispersion tube assembly including a connecting pipe and multiple dispersion tubes;

[0025] The connecting pipe is rotatably sleeved onto the end of the outlet pipe located inside the cooling tank. Multiple dispersion tubes are uniformly fixed and connected to the upper side of the connecting pipe, and multiple evenly distributed dispersion holes are provided on one side of the horizontal side of the dispersion tubes, and the dispersion holes on the multiple dispersion tubes are all arranged in the same direction. When the coolant is sprayed out through the dispersion holes, the reverse thrust generated causes the entire dispersion tube assembly to rotate, thereby disturbing the coolant inside the cooling tank, making the coolant temperature uniform in all parts of the cooling tank, and improving the cooling effect on the heating plate.

[0026] As a further supplement to this application, the connecting pipe is threaded onto the end of the outlet pipe located inside the cooling box, and the connecting pipe and the outlet pipe are in a two-way threaded fit; when the coolant is sprayed out through the dispersion hole, the reverse thrust generated causes the entire dispersion tube assembly to rotate, and under the action of the two-way threaded fit, the entire dispersion tube assembly moves up and down reciprocally, resulting in a better disturbance effect.

[0027] As a further supplement to this application, an elastic heat-conducting assembly connected to the inside of the cooling box is installed at the lower end of the mounting base, and a heat-conducting plate is installed at the lower end of the elastic heat-conducting assembly.

[0028] As a further supplement to this application, the flexible thermally conductive assembly includes a sleeve, a second thermocouple, a sealing slip ring, and a compression spring;

[0029] The tube sleeve is fixed through the mounting base, the sealing slip ring is slidably installed on the inner side of the tube sleeve and fixedly sleeved on the outer side of the middle of the second thermocouple, the compression spring is fixed between the bottom end of the tube sleeve and the sealing slip ring, the heat conduction plate is in contact with the surface of the frame bar, and works with the second thermocouple to recover the heat on the frame bar, while effectively reducing the adverse effects of the high temperature of welding on the frame bar.

[0030] As a further supplement to this application, multiple heat pipes are fixed at equal intervals on the side of the cooling box, and the heat pipes extend through to the inside of the cooling box; the heat pipes have good thermal conductivity and can quickly remove heat from the coolant, thereby ensuring the stable cooling effect of the coolant and the efficient conversion of heat to electrical energy by the thermocouple.

[0031] In summary, by using thermocouple 1 to monitor the temperature change of the heating plate in real time, when the heat generated during the welding process exceeds the heat dissipation capacity of the heating plate itself, thermocouple 1 converts this excess heat into electrical energy, preventing the heating plate from overheating and causing deformation of the welded joint of the frame strip, thereby improving the welding quality. Furthermore, the electrical energy generated by thermocouple 1 is collected and converted into a higher voltage output using a thermoelectric power generation module, achieving efficient energy utilization. By extending thermocouple 1 to the inside of the cooling box, the temperature difference between the two ends of thermocouple 1 can be further increased using coolant, thereby improving the heat-to-electricity conversion rate. In addition, in conjunction with the circulation pump, the reverse thrust generated when the coolant is sprayed out through the dispersion holes causes the entire dispersion tube assembly to rotate, thereby disturbing the coolant inside the cooling tank and making the coolant temperature uniform in all parts of the cooling tank, resulting in better cooling effect on the heating plate. The heat-conducting plate is in contact with the surface of the frame bar, and in conjunction with thermocouple 2, it recovers the heat on the frame bar, while effectively reducing the adverse effects of the high temperature of welding on the frame bar. Finally, the heat pipe can quickly remove the heat from the coolant, thereby ensuring the stable cooling effect of the coolant and the efficient conversion of heat to electrical energy by the thermocouple.

[0042] The following describes five embodiments of this application in detail with reference to the accompanying drawings.

[0043] Implementation method 1:

[0044] This invention provides a novel welding device for door and window processing. Please refer to [link / reference]. Figure 1-5 It includes a welding platform 1, a heating mechanism, and a thermoelectric power generation module.

[0045] The upper end of the welding platform 1 is equipped with a main positioning mechanism and a side positioning mechanism. The two side positioning mechanisms are located on both sides of the main positioning mechanism and are set at a 90-degree angle to the main positioning mechanism. The two heating mechanisms are installed on the side of the two side positioning mechanisms that are close to the main positioning mechanism. The heating mechanism includes a lifting push rod 8 and a heating component 9.

[0046] Regarding the primary positioning mechanism and the secondary positioning mechanism, specifically, as follows: Figure 1As shown, the main positioning mechanism includes a limiting push seat 2, a welding push rod 3, and a clamping assembly. The clamping assembly includes a clamping push rod 6 and a clamping plate 7. The clamping plate 7 is installed at the output end of the clamping push rod 6. The welding push rod 3 is installed at the upper end of the welding platform 1. The limiting push seat 2 is installed at the output end of the welding push rod 3. The clamping push rod 6 is installed at the upper middle part of the limiting push seat 2 via a mounting bracket. The side positioning mechanism includes a limiting abutment 4, an adjusting push rod 5, and a clamping assembly. The adjusting push rod 5 is installed at the upper end of the welding platform 1. The limiting abutment 4 is installed at the output end of the adjusting push rod 5. The clamping push rod 6 is installed at the upper middle part of the limiting abutment 4 via a mounting bracket. The lifting push rod 8 is installed at the side end of the limiting abutment 4 near the limiting push seat 2.

[0047] Among them, such as Figure 2-5 As shown, the heating assembly 9 includes a mounting base 91 and a heating plate 92. The mounting base 91 is installed at the output end of the lifting push rod 8. The heating plate 92 is vertically installed at the lower middle of the mounting base 91, and the heating plate 92 is set at a 45-degree angle with the main positioning mechanism. Multiple thermocouples 93 are fixed at equal intervals at the lower end of the mounting base 91. Multiple vertical tube grooves 9201 are provided along the length of the upper end of the heating plate 92. The multiple thermocouples 93 are inserted into the inner side of the multiple tube grooves 9201 in a corresponding manner. Thermocouples 93 are used to monitor the temperature change of the heating plate 92 in real time. When the heat generated during the welding process exceeds the heat dissipation capacity of the heating plate 92 itself, the thermocouples 93 convert this excess heat into electrical energy, avoiding the overheating of the heating plate 92 and causing deformation of the welded joint of the frame strip, thereby improving the welding quality.

[0048] The thermoelectric power generation module is mounted on the mounting base 91 and connected to thermocouple 93. The thermoelectric power generation module collects the electrical energy generated by thermocouple 93 and converts it into a higher voltage output, thereby realizing the efficient use of energy.

[0049] The lower end of the mounting base 91 is equipped with an elastic heat-conducting assembly 98 that communicates with the inside of the cooling box 94. The lower end of the elastic heat-conducting assembly 98 is equipped with a heat-conducting plate 99. The elastic heat-conducting assembly 98 includes a sleeve 981, a second thermocouple 982, a sealing slip ring 983, and a compression spring 984. The sleeve 981 is fixedly inserted through the mounting base 91. The sealing slip ring 983 is slidably installed on the inside of the sleeve 981 and fixedly sleeved on the outer side of the middle of the second thermocouple 982. The compression spring 984 is fixed between the bottom end of the sleeve 981 and the sealing slip ring 983. The heat-conducting plate 99 is in contact with the surface of the frame bar and works with the second thermocouple 982 to recover heat from the frame bar, while effectively reducing the adverse effects of the high temperature of welding on the frame bar.

[0050] The second implementation method:

[0051] This embodiment, based on embodiment 1, adds the following structure to improve the heat-to-electrical energy conversion rate of thermocouple 93. The specific configuration is as follows: Figure 2 and Figure 4 As shown, a cooling box 94 is installed on the upper end of the mounting base 91. Coolant is contained inside the cooling box 94. The upper end of thermocouple 93 passes through the mounting base 91 and extends to the inside of the cooling box 94. The coolant can further increase the temperature difference between the two ends of thermocouple 93, thereby improving the heat-to-electrical energy conversion rate.

[0052] The third implementation method:

[0053] This embodiment adds the following structure to embodiment 2, thereby enhancing the heat dissipation effect of the heating plate 92. The specific settings are as follows: Figure 4 , Figure 7 and Figure 8 As shown, the lower end of the mounting base 91 is equipped with a liquid inlet pipe 95 and a liquid outlet pipe 96 that are connected to each other. Both the liquid inlet pipe 95 and the liquid outlet pipe 96 are connected to the inside of the cooling box 94. A circulation pump is installed on the liquid inlet pipe 95, and a one-way valve is installed on the liquid outlet pipe 96. The heating plate 92 is provided with a pipe groove 9202 that is compatible with the liquid inlet pipe 95 and the liquid outlet pipe 96.

[0054] Based on the above structure, a circulating pump can be used to circulate and cool the heating plate 92 with the coolant in the cooling tank 94, further enhancing the heat dissipation effect of the heating plate 92.

[0055] Among them, such as Figure 4 , Figure 7 and Figure 8 As shown, a dispersion tube assembly 97 is provided inside the cooling tank 94. The dispersion tube assembly 97 includes a connecting pipe 971 and multiple dispersion tubes 972. The connecting pipe 971 is rotatably sleeved on the end of the liquid outlet pipe 96 located inside the cooling tank 94. Multiple dispersion tubes 972 are uniformly fixed and connected to the upper side of the connecting pipe 971. Multiple uniformly distributed dispersion holes 97201 are provided on one side of the horizontal side of the dispersion tube 972. The dispersion holes 97201 on the multiple dispersion tubes 972 are all arranged in the same direction.

[0056] Based on the above structural arrangement, the reverse thrust generated when the coolant is sprayed out through the dispersion hole 97201 causes the dispersion tube assembly 97 to rotate as a whole, thereby disturbing the coolant inside the cooling box 94, making the coolant temperature of each part inside the cooling box 94 uniform, and improving the cooling effect on the heating plate 92.

[0057] The fourth implementation method:

[0058] Based on Embodiment 3, this embodiment adds the following structure to enhance the disturbance effect on the coolant. The specific configuration is as follows: the connecting pipe 971 is threadedly sleeved at the end of the outlet pipe 96 located inside the cooling tank 94, and the connecting pipe 971 and the outlet pipe 96 are in a bidirectional threaded fit; when the coolant is sprayed out through the dispersion hole 97201, the reverse thrust generated causes the dispersion tube assembly 97 to rotate as a whole, and under the action of the bidirectional threaded fit, the dispersion tube assembly 97 moves up and down reciprocally, resulting in a better disturbance effect.

[0059] Fifth implementation method:

[0060] Based on embodiment 4, this embodiment adds the following structure to enable the coolant to cool down rapidly. Specifically, the structure is as follows: multiple heat pipes 910 are fixed at equal intervals on the side of the cooling box 94, and the heat pipes 910 extend through to the inside of the cooling box 94. The heat pipes 910 have good thermal conductivity and can quickly remove heat from the coolant, thereby ensuring the stable cooling effect of the coolant and the efficient conversion of heat to electrical energy by the thermocouple.

[0061] Compared to existing technologies, this solution uses a thermocouple 93 to monitor the temperature change of the heating plate 92 in real time. When the heat generated during welding exceeds the heat dissipation capacity of the heating plate 92, the thermocouple 93 converts this excess heat into electrical energy, preventing the heating plate 92 from overheating and causing deformation at the weld joint of the frame strip, thereby improving the welding quality. Furthermore, the thermoelectric power generation module collects the electrical energy generated by the thermocouple 93 and converts it into a higher voltage output, achieving efficient energy utilization.

[0062] Compared with the prior art, in this solution, by extending thermocouple 93 to the inside of cooling box 94, the temperature difference between the two ends of thermocouple 93 can be further increased by using coolant, thereby improving the heat-to-electrical energy conversion rate.

[0063] Compared to existing technologies, in this solution, in conjunction with the action of the circulating pump, the reverse thrust generated when the coolant is sprayed out through the dispersion hole 97201 causes the entire dispersion tube assembly 97 to rotate, thereby disturbing the coolant inside the cooling box 94, making the coolant temperature of each part inside the cooling box 94 uniform, and improving the cooling effect on the heating plate 92.

[0064] Compared to existing technologies, in this solution, the heat-conducting plate 99 is in contact with the surface of the frame strip, and the thermocouple 982 recovers the heat on the frame strip. At the same time, it can effectively reduce the adverse effects of the high temperature of welding on the frame strip. Finally, the heat pipe 910 can quickly remove the heat from the coolant, thereby ensuring the stable cooling effect of the coolant and the efficient conversion of heat to electrical energy by the thermocouple.

[0065] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
