Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to an automatic welding manufacturing system for doors and windows and an application method thereof. Background Art

[0002] In the production process of doors and windows, various profiles are usually used to form the main frame, which is then used to install door panels, glass and other components to form doors and windows; traditional manual welding is inefficient, and some doors and windows use robotic arms for automated welding, but only one welding point can be welded at a time, and the overall efficiency is not high enough due to repeated manual clamping of profiles. Therefore, four-corner welding machines are gradually being widely used.

[0003] The existing utility model patent with authorization announcement number CN221019389U discloses a self-positioning device for a horizontal CNC four-corner welding machine, which relates to the technical field of welding machines; and the utility model includes a base, the upper side of the base is fixedly connected to a first slide rail, and the upper end of the first slide rail is slidably connected to a second slide rail, the upper end of the second slide rail is slidably connected to a positioning seat, and the inner side of the upper end of the positioning seat is fixedly connected to a welder, the outer side of one end of the base is fixedly connected to a control box, and an automatic positioning mechanism is arranged at the lower end of the positioning seat, the automatic positioning mechanism includes a power unit, a limit unit, a connecting block, a telescopic unit, an elastic unit and an extrusion unit, and a power unit is arranged inside the lower end of the positioning seat.

[0004] As in the above technical solution, four positioning seats are used to fix the profiles. Four profiles need to be placed one by one during production. After the frame is welded, the extrusion plate needs to be driven away from the frame by the telescopic rod, and then the frame is taken out manually or mechanically. The whole operation process is relatively time-consuming and affects production efficiency.

[0005] Among the fixed structures currently used by conventional four-corner welding machines, a clamping mechanism is more often used. The clamping mechanism clamps the profile from the upper side. When the frame needs to be taken out, the clamping mechanism is loosened and the positioning seat is directly displaced. In this way, the distance between two of the positioning seats relative to the other two positioning seats becomes larger, and the welded frame can be taken out. In this type of four-corner welding machine, two of the positioning seats will be moved closer to the other two positioning seats before the profile is placed. After one profile is placed, the two positioning seats will move away from each other, and then the other three profiles can be placed. However, due to the influence of the profile placement method and the door and window frame output method, there is still a problem of low efficiency. Summary of the invention

[0006] In view of this, the present invention proposes an automated door and window welding manufacturing system and an application method thereof which have high feeding and finished product output efficiency and can effectively improve production efficiency, so as to solve the problem that the existing welding machines are still subject to the influence of the profile insertion method and the door and window frame output method, and have low efficiency.

[0065] Repeat the above steps to continuously manufacture door and window frames.

[0066] Compared with the prior art, the automatic door and window welding manufacturing system and its application method of the present invention have the following advantages:

[0067] Beneficial effects:

[0068] (1) By setting up a feeding mechanism, only one long profile needs to be put in, and the feeding mechanism can convey the profile and cut the longitudinal frame through the cutting mechanism, and then convey the longitudinal frame to between the welding modules. In this way, only the transverse frame needs to be placed manually, and there is no need to feed the longitudinal frame multiple times, which can effectively improve the processing efficiency; and a second notch is provided on the two welding modules far away from the feeding mechanism, so that the welded door and window frames can be directly ejected by the longitudinal frame input later, which improves the convenience of finished product output, thereby effectively improving production efficiency;

[0069] (2) In the feeding mechanism, the first clamp is driven by the linear drive member to perform linear displacement, so that it can selectively clamp different points of the profile to feed the profile progressively; and after the front end of the profile is cut to form a longitudinal frame, the profile can be returned after pushing the longitudinal frame into place to prepare for the subsequent cutting process, which is very convenient to use; at the same time, the feeding mechanism is provided with a first guide plate and a second guide plate, the first guide plate is provided on the base frame, and the second guide plate is provided on the welding module, so that the profile can still maintain an accurate position after crossing the cutting station of the cutting mechanism, so that the subsequent welding work can be carried out normally;

[0070] (3) The welding module integrates a welding gun, a positioning mechanism and an exhaust duct through a box body, so that the horizontal frame and the vertical frame constituting the door and window frame can be locked and fixed by the positioning mechanism so as to be welded by a welding gun; at the same time, since the box body is provided with a first notch, when the exhaust duct is connected to a negative pressure suction device, the fume generated by welding can be collected to ensure an environmentally friendly and clean production environment;

[0071] (4) In the positioning mechanism, the cam is driven to rotate by a motor to realize the compression of the horizontal frame and the vertical frame, so that when the compression is released, it does not interfere with the output of the finished frame; at the same time, a stopper protrusion is integrated on the protruding part of the cam, and a limit plate is also provided in the box of the welding module, so that the limit plate can limit the length direction of the horizontal frame, and the stopper protrusion of the cam can limit the width direction of the horizontal frame. This structure not only does not interfere with the installation of the frame, but also can quickly lock and fix the frame later, which has the advantages of convenient application and fast action;

[0072] (5) By setting a second clamp, the longitudinal frame can be clamped and fixed; the second clamp is integrated with a first detection module, so that the transverse frames on both sides of the longitudinal frame can be detected to be in place, thereby ensuring that the size of the frame is correct, which helps to improve the quality of the finished product;

[0073] (6) Three of the welding modules are provided with a laser transmitter, a laser receiver and a mirror component to form a second detection module, so that the welding modules can be positioned to determine the assembly accuracy of the welding manufacturing system, thereby facilitating the quality of the finished product; at the same time, when the two welding modules far away from the feeding mechanism are displaced, the second detection module can ensure that the welding modules move into place when they are reset, thereby ensuring the accuracy of the movement.

DETAILED DESCRIPTION

[0095] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0096] like Figures 1 to 19 As shown, the automatic welding manufacturing system for doors and windows of the present invention comprises a feeding mechanism 1, a welding module 2, a cutting mechanism 3, an intermediate plate 4, a guide rail 5, a second fixture 6, a first detection module 7, a second detection module 8 and a frame 9;

[0097] It is used to cut the profile 300 into longitudinal frames 200 and weld the longitudinal frames 200 with the transverse frames 100 to form a door and window frame. The frame is used in but not limited to the production of doors and windows.

[0098] like Figures 1 to 5As shown, two feeding mechanisms 1 are arranged in parallel, and the feeding mechanisms 1 are linear conveying modules; four welding modules 2 are arranged in a rectangular array, and each feeding mechanism 1 is linearly arranged with two welding modules 2; first notches 201 are arranged at opposite corners of the four welding modules 2, and the welding modules 2 are connected in the feeding direction of the feeding mechanism 1; the two welding modules 2 far away from the feeding mechanism 1 are provided with second notches 202 on their opposite surfaces; the feeding mechanism 1 is used to convey the profile 300, and convey the longitudinal frame 200 between the welding modules 2, and eject the door and window frame formed by welding the transverse frame 100 and the longitudinal frame 200; the cutting mechanism 3 is arranged between the feeding mechanism 1 and the welding module 2, and is used to cut the profile 300 to form the longitudinal frame 200;

[0099] As in the above structure, the feeding mechanism 1 is used to convey the profile 300. When the profile 300 passes through the cutting mechanism 3, it will be cut by the cutting mechanism 3 to form a longitudinal frame 200. After that, the feeding mechanism 1 will continue to feed the profile 300 and push the longitudinal frame 200 into between the welding modules 2.

[0100] In order to facilitate the movement of the longitudinal frame 200 between the welding modules 2, as shown in FIG. Fig.11 As shown, the welding module 2 is connected in the feeding direction of the feeding mechanism 1 to allow the longitudinal frame 200 to pass through;

[0101] A welding assembly and a positioning assembly are installed in the welding module 2 to position the horizontal frame 100 and the vertical frame 200 and perform welding work. The first notch 201 of the welding module 2 is a working area so that the welding assembly and the positioning assembly can position and weld the horizontal frame 100 and the vertical frame 200;

[0102] The longitudinal frame 200 is fed into the welding module 2 and welded with the transverse frame 100 to form a door and window frame;

[0103] The second notches 202 are arranged on the two welding modules 2 far from the feeding mechanism 1, so that after welding to form the door and window frame, the feeding mechanism 1 will continue to push in the next longitudinal frame 200, and the longitudinal frame 200 will push out the welded door and window frame, thereby realizing automatic discharging;

[0104] This structure can effectively improve production efficiency because it integrates automatic feeding, cutting and automatic discharging functions.

[0105] In some embodiments, a discharge conveyor belt is provided at one end of the manufacturing system away from the feeding mechanism, so that after the door and window frame part is overlapped on the discharge conveyor belt, automatic delivery of finished products can be achieved.

[0106] like Figure 7 , Figure 8 and Fig.19As shown, the feeding mechanism 1 includes a base frame 11, a first guide plate 12, a second guide plate 13, a linear drive member 14 and a first clamp 15, wherein the base frame 11 is relatively fixed to the welding module 2 and corresponds to the through direction of the welding module 2; the first guide plate 12 is arranged on the base frame 11 and is used to limit the profile 300; the second guide plate 13 is connected to the welding module 2, and the second guide plate 13 partially extends to the outside of the welding module 2 and is spaced from the first guide plate 12; the linear drive member 14 is arranged in parallel with the base frame 11; the first clamp 15 is arranged on the movable end of the linear drive member 14 and is used to clamp and convey the profile 300;

[0107] As in the above structure, when the feeding mechanism 1 is working, the bottom surface of the profile 300 is first slidably matched with the first guide plate 12, and then the profile 300 is clamped by the first clamp 15, and then the first clamp 15 and the profile 300 are driven to move by the linear drive member 14;

[0108] The linear drive member 14 adopts a screw nut slide to achieve reciprocating movement, and the first clamp 15 selectively clamps different points of the profile 300 to achieve gradual conveying of the profile 300;

[0109] Since the profile 300 needs to be cut by the cutting mechanism 3, a gap should be reserved between the first guide plate 12 and the welding module 2 to facilitate the downward discharge of the scraps 400 and welding slag;

[0110] In order to stabilize the position of the profile 300 after entering the welding module 2, a second guide plate 13 is provided on the second welding module 2 to position the profile 300; the portion of the profile 300 located on the second guide plate 13 is cut by the cutting mechanism 3 to form a longitudinal frame 200.

[0111] like Fig.18 As shown, the first clamp 15 includes a bracket 151, a bidirectional cylinder 152, a clamping claw 153, a pressing cylinder 154 and a pressing plate 155, wherein the bracket 151 adopts a door-shaped frame, and both ends are connected to the movable end of a linear drive member 14; the bidirectional cylinder 152 is arranged in the bracket 151, and a clamping claw 153 is arranged at both movable ends; the pressing cylinder 154 is arranged in the bracket 151 and is located between the two clamping claws 153; the pressing plate 155 is arranged on the movable end of the clamping cylinder 154;

[0112] As in the above structure, when the first clamp 15 is working, the two ends of the bracket 151 are located on both sides of the base frame 11. The two-way cylinder 152 drives the two clamps 153 to clamp the profile 300 for transportation, and can also synchronously cooperate with the clamping cylinder 154 to clamp the profile 300 for transportation to ensure the stability of transportation.

[0113] like Fig. 9 and Fig.19As shown, the cutting mechanism 3 includes a carrier 31, a first linear module 32, a second linear module 33, a third linear module 34 and a cutter 35, wherein the carrier 31 is connected to the welding module 2 close to the feeding mechanism 1; the first linear module 32, the second linear module 33 and the third linear module 34 constitute a three-axis displacement mechanism; the first linear module 32 is arranged on the carrier 31, and the feeding direction of the first linear module 32 is arranged at an angle to the feeding direction of the feeding mechanism 1; the cutter 35 is arranged on the movable end of the third linear module 34;

[0114] As in the above mechanism, in order to improve the convenience of integration, the cutting mechanism 3 is directly connected to the welding module 2 through the carrier 31.

[0115] In the cutting mechanism 3, a three-axis displacement mechanism is formed by the first linear module 32, the second linear module 33 and the third linear module 34, and the three linear modules can be formed by a screw nut seat;

[0116] The feeding direction of the first linear module 32 is set at an angle with the feeding direction of the feeding mechanism 1. When working, the second linear module 33 first drives the third linear module 34 and the cutter 35 to move to cut one end of the profile 300 into an angle shape, and then the feeding mechanism 1 conveys the profile 300 to the welding module 2;

[0117] Subsequently, the first linear module 32 simultaneously drives the second linear module 33, the third linear module 34 and the cutter 35 to move to cut the profile 300, thereby forming a longitudinal frame 200, the two ends of which have bevels to facilitate subsequent welding;

[0118] The third linear module 34 is used to adaptively adjust the height of the cutter 35 , thereby ensuring that the cutting of the profile 300 is carried out normally.

[0119] During subsequent processing, in order to ensure that the corners of the longitudinal frame 200 and the transverse frame 100 can be welded correspondingly, it is necessary to cut the corners of the profile again to cut off the corner material 400 to adjust the corners of the profile 300.

[0120] In some embodiments, the cutting mechanism 3 is integrated with a protective plate 36 and a window 301. The protective plate 36 is connected to the carrier 31 and the welding module 2, and a window 301 is opened, wherein the window 301 is closed by a transparent PVC plate, or a dark transparent plate, to avoid splashing of cutting debris, which is beneficial to protecting the safety of the operator and convenient for the operator to observe the working condition of the cutting mechanism 3.

[0121] like Figure 2 and Figure 8As shown, the welding module 2 includes a box body 21, a welding gun 22, a positioning mechanism 23 and an exhaust pipe 24, wherein the box body 21 is relatively fixed to the feeding mechanism 1, and a first notch 201 and a second notch 202 are provided on the box body 21; the welding gun 22 is arranged in the box body 21 and corresponds to the first notch 201; two positioning mechanisms 23 are arranged in the box body 21, which are used for positioning and locking the horizontal frame 100 and the longitudinal frame 200; the exhaust pipe 24 is arranged on the box body 21, and the exhaust pipe 24 is connected with the inside of the box body 21;

[0122] As in the above structure, the box 21 is a carrier, and the welding gun 22 is a welding assembly, which is arranged together with the positioning mechanism 23 in the box 21 for welding and positioning the horizontal frame 100 and the vertical frame 200;

[0123] The box body 21 is provided with a first slot 201 and a second slot 202 for conveying the profile 300 and the door and window frame;

[0124] The welding gun 22 is installed in the box 21 through a driving member such as a mechanical arm, so that the welding gun 22 can be displaced, thereby welding the connection point between the horizontal frame 100 and the vertical frame 200;

[0125] The positioning mechanism 23 positions the horizontal frame 100 and the vertical frame 200 to ensure the splicing accuracy, and also fixes the horizontal frame 100 and the vertical frame 200 so that the finished frame formed by welding has good accuracy;

[0126] In order to remove welding fumes, an exhaust duct 24 is provided on the box body 21. Among the boxes 21 of the four welding modules 2, two are only provided with the first slot 201, and the other two are also provided with the second slot 202. Therefore, after the exhaust duct is connected to the negative pressure suction device through the pipeline, negative pressure can be effectively formed to remove the welding fumes to ensure a good working environment.

[0127] like Figure 2 , Fig.12 and Fig.13 As shown, the positioning mechanism 23 includes a motor 231, a cam 232, a stop protrusion 233 and a limit plate 234, wherein the motor 231 is connected to the inner wall of the box body 21; the cam 232 is arranged on the main shaft of the motor 231; the stop protrusion 233 is arranged on the protruding portion 2321 of the cam 232, and the protruding direction of the stop protrusion 233 and the protruding direction of the protruding portion 2321 are at an angle of forty-five degrees; the limit plate 234 is arranged in the box body 21, and the limit plate 234 is parallel to the feeding direction of the profile 300;

[0128] For the above structure, see Figure 2 The limiting plate 234 is used to limit the length direction of the horizontal frame 100 to prevent the limiting plate 234 from moving;

[0129] The cam 232 is used to press the transverse frame 100 and the longitudinal frame 200. In order to ensure welding accuracy, the width direction of the transverse frame 100 is limited by the stop protrusion 233 to avoid misalignment when the longitudinal frame 200 pushes the transverse frame 100.

[0130] See also Fig.14 , which is the initial state of the positioning mechanism 23, the cam 232 and the stop protrusion 233 do not contact the frame;

[0131] like Fig.15 As shown, the motor 231 drives the cam 232 to rotate forty-five degrees, and at this time the stop protrusion 233 faces downward, so that after the transverse frame 100 away from the feeding mechanism 1 is placed, one side of the width direction thereof will be limited by the stop protrusion 233; then, after the feeding mechanism 1 pushes into the longitudinal frame 200 through the profile 300, the longitudinal frame 200 will push the transverse frame 100 to ensure that the position of the transverse frame 100 is correct;

[0132] See also Fig.16 Then the motor 231 drives the cam 232 to rotate forty-five degrees again, and the transverse frame 100 is pressed and fixed by the protrusion 2321, and then the second transverse frame 100 is placed on the side close to the feeding mechanism 1, and then the frame can be welded;

[0133] After welding is completed, the motor 231 drives the cam 232 to reverse 90 degrees, so that the protrusion 2321 of the cam 232 and the stop protrusion 233 are separated from the frame, so that the finished frame can be output outward. The structure is simple and reasonable, and the various processes do not interfere with each other.

[0134] like Figure 3 , Figure 8 and Fig.11 As shown, the middle plate 4 is arranged between two welding modules 2 which are in a linear array with the feeding mechanism 1; two guide rails 5 are arranged on both sides of the middle plate 4, and one guide rail 5 on each side corresponds to the feeding mechanism 1; the second guide plate 13 extends to the outer part of the welding module 2, and abuts against the guide rail 5 corresponding to the feeding mechanism 1; the welding module 2 is slidably arranged on the guide rail 5; the second clamp 6 is arranged on the middle plate 4, and is used to fix the longitudinal frame 200;

[0135] As in the above structure, when the welding module 2 is set, it is slidably mounted on the guide rails 5 on both sides of the middle plate, so that when the door and window frames need to be output, the four welding modules 2 can be separated to both sides to facilitate the robot or other automation to move the welded door and window frames out from one side;

[0136] Specifically, the welding module 2 can be driven and displaced by a screw nut slide;

[0137] In order to ensure that the position of the longitudinal frame 200 is stable when the transverse frame 100 close to the feeding mechanism 1 is assembled, a second clamp 6 is provided on the middle plate 4 between the welding modules 2. When the longitudinal frame 200 is against the transverse frame 100 away from the feeding mechanism 1, the second clamp 6 can clamp and fix the longitudinal frame 200.

[0138] In this structure, there is a guide rail 5 at the bottom of the welding module 2 corresponding to the feeding mechanism 1, so that the second guide plate 13 extending to the outside of the welding module 2 can be supported on the guide rail 5, so that the guide rail 5 and the second guide plate 13 are in contact with each other to achieve structural reinforcement, thereby avoiding the problem of deformation and dislocation of the second guide plate 13 during long-term operation.

[0139] like Figure 4 As shown, the second fixture 6 includes a cylinder 61, a push plate 62, a bidirectional motor 63, a connecting rod 64 and a clamping plate 65, wherein the cylinder 61 is arranged on the middle plate 4; the push plate 62 is arranged on the movable end of the cylinder 61; the bidirectional motor 63 is arranged on the bottom surface of the middle plate 4, and the two output shafts of the bidirectional motor 63 are both provided with connecting rods 64; the clamping plate 65 is connected to the connecting rod 64; the first detection module 7 is a diffuse reflection laser detector, and the first detection module 7 is respectively provided with one at both ends of the clamping plate 65;

[0140] As in the above structure, the second clamp 6 will also perform a detection process when performing the clamping action;

[0141] When working, the two positioning mechanisms 23 away from the feeding mechanism 1 should be kept as follows: Fig.15 In the state shown, when the horizontal frame 100 is placed away from the feeding mechanism 1, the cylinder 61 first pushes the push plate 62 into place, and then the bidirectional motor 63 drives the clamping plate 65 to flip upward through the connecting rod 64, but the clamping plate 65 is not completely parallel to the push plate 62;

[0142] At this time, the feeding mechanism 1 pushes into the longitudinal frame 200, and the push plate 62 and the clamping plate 65 play a guiding role until the longitudinal frame 200 abuts against the transverse frame 100 away from the feeding mechanism 1. The first detection module 7 away from the feeding mechanism 1 detects that the spacing between it and the transverse frame 100 away from the feeding mechanism 1 is correct, and the bidirectional motor 63 drives the clamping plate 65 to be completely clamped through the connecting rod 64;

[0143] Then, the transverse frame 100 close to the feeding mechanism 1 is put in, and the first detection module 7 close to the feeding mechanism 1 detects that the distance between it and the transverse frame 100 close to the feeding mechanism 1 is correct, and then clamping is performed;

[0144] After the two horizontal frames 100 are limited by the limiting plates 234 in the length direction, the width direction is accurately detected by the first detection module 7, and the longitudinal frame 200 is limited by the second clamp 6, it means that the positions of the four frames are correct. At this time, the eight positioning mechanisms 23 are used to achieve complete locking and fixing, and welding work can begin.

[0145] In some embodiments, Fig.17 As shown, the first detection module 7 away from the feeding mechanism 1 is replaced by a tightening cylinder 66. Since the corners of the transverse frame 100 and the longitudinal frame 200 are oblique angles, when the two longitudinal frames 200 abut against the transverse frame 100, it is ensured that the transverse frame 100 is attached to the stop protrusion 233 of the positioning mechanism 23;

[0146] In this way, when the second clamp 6 is clamped, the clamping cylinder 66 can cooperate with the stop protrusion 233 to clamp the transverse frame 100. At this time, the cam 232 does not need to rotate to press the transverse frame 100 with the protrusion 2321 to prevent the stop protrusion 233 from wearing.

[0147] like Fig.10 As shown, the second detection module 8 includes a laser transmitter 81, a laser receiver 82 and a mirror 83, wherein the laser transmitter 81 is arranged on one of the welding modules 2 far away from the feeding mechanism 1; the laser receiver 82 is arranged on another welding module 2 far away from the feeding mechanism 1; and the mirror 83 is arranged on one of the welding modules 2 close to the feeding mechanism 1;

[0148] As in the above structure, since the positioning of the horizontal frame 100 and the vertical frame 200 depends on the positioning mechanism 23 set inside the welding module 2, whether the positions of the four welding modules 2 are correct will directly affect the welding accuracy of the door and window frames; if the welding module 2 adopts a slide rail movement method to realize automatic material discharge, it is necessary to ensure that the position is correct when resetting;

[0149] In actual application, the two welding modules 2 close to the feeding mechanism 1 do not move, and their relative positions are stable. Only the other two welding modules 2 move relatively to leave space for discharging.

[0150] In this structure, when the positions of the four welding modules 2 are correct, the light emitted by the laser transmitter 81 will be reflected by the mirror 83 to be received by the laser receiver 82. At this time, the relative positions of the three welding modules 2 can be ensured to be correct. Since the two welding modules 2 close to the feeding mechanism 1 do not move, the positions of the four welding modules 2 can be ensured to be relatively correct, thereby ensuring the structural accuracy.

[0151] like Figure 3 and Figure 6As shown, the frame 9 includes a bottom plate 91 and a support column 92, wherein the bottom plate 91 is provided with a first groove 901 to form an operation area; the feeding mechanism 1 and the welding module 2 are arranged on the frame 9, and the cutting mechanism 3 is arranged on the welding module 2; the bottom plate 91 is provided with a second groove 902 corresponding to the cutting mechanism 3; the support column 92 supports the bottom plate 91;

[0152] As in the above structure, the bottom plate 91 is used to carry the feeding mechanism 1 and the welding module 2. To improve the convenience of integration, the cutting mechanism 3 is directly arranged on the welding module 2;

[0153] The first groove 901 is provided to form an operation area for the operator to enter for operation, for example, to place the horizontal frame 100; the second groove 902 is used to drain the cut scraps 400;

[0154] The bottom plate 91 is suspended by supporting pillars 92 , so that a material frame can be arranged at the bottom for collecting the scraps 400 .

[0155] The application method of the door and window automatic welding manufacturing system of the present invention comprises the following steps:

[0156] S1, placing a transverse frame 100 between two welding modules 2 away from the feeding mechanism 1,

[0157] S2, conveying two profiles 300 through the feeding mechanism 1,

[0158] S3, cutting the profile 300 by the cutting mechanism 3 to form two longitudinal frames 200,

[0159] S4, the profile 300 is pushed by the feeding mechanism 1 to move, and the profile 300 pushes the longitudinal frame 200 to move into place until the end is in contact with the transverse frame 100.

[0160] S5, the profile 300 is driven back by the feeding mechanism 1, and at the same time, a second transverse frame 100 is placed between the two welding modules 2 close to the feeding mechanism 1.

[0161] S6, welding the two horizontal frames 100 and the two vertical frames 200 at opposite corners by welding module 2 to form a door and window frame.

[0162] S7, the profile 300 is pushed to move by the feeding mechanism 1, and the door and window frame is pushed out by the profile 300, and then the feeding mechanism 1 drives the profile 300 to move back and cut again, and at the same time, the staff takes the horizontal frame 100 again;

[0163] Repeat the above steps to continuously manufacture door and window frames.

[0164] In this process method, step S2 is only required for the first time, and the profile 300 is subsequently cut when it moves back, while the staff performs step S1 to place the horizontal frame 100;

[0165] Then, steps S4 to S7 are executed.

[0166] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
