[0001] The present invention relates to the technical field of welding devices, and particularly relates to a welding device for metal door and window processing. Background Art

[0002] With the continuous development of the construction industry, the demand for metal doors and windows continues to grow. Moreover, with the diversified and high-end development of buildings, higher standards are required for the quality, precision, aesthetics, etc. of metal doors and windows. Traditional manual welding or simple welding equipment is difficult to meet the large-scale and high-quality production requirements, which promotes the research and development of more advanced, efficient, and automated welding devices. With the continuous development of modern welding technologies, new processes such as gas shielded welding, laser welding, and electron beam welding have emerged continuously. These processes have the advantages of high welding quality, fast speed, and small heat affected zone, providing technical support for the upgrade of metal door and window welding devices. Applying these advanced processes to the welding device for metal door and window processing can improve the welding quality and efficiency.

The left side of the top of the machine table is fixedly connected with a jig support seat. The left side of the top of the jig support seat is fixedly connected with a left-station jig. The right side of the top of the jig support seat is fixedly connected with a right-station jig. The inner side of the front of the machine table is embedded with an operation screen. The rear side of the top of the machine table is fixedly connected with a step wire feeder. The output end of the step wire feeder is fixedly connected with a welding head, and the bottom of the welding head is fixedly connected with a flat wire feeding bracket. Through the coordinated use of the left-station jig, flat wire feeding bracket, welding head, Z-axis linear module, wire feeding disc fixing bracket, right-station jig, jig support seat, X-axis linear module, laser, and step wire feeder, this patent has strong adaptability to the sizes of non-standard workpieces, convenient workpiece clamping operations, and innovative research and development on the wire feeding bracket for the automatic wire filling device, achieving a simple, compact, and stable wire filling effect.

[0004] However, in the prior art, the following problems exist: When welding doors and windows in the prior art, a multi-process operation mode is usually adopted. Workers first weld two adjacent materials into an L-shaped frame, and then workers in the subsequent process weld two L-shaped frames into a door and window frame, and then perform subsequent process operations. However, when welding the L-shaped frame, workers need to manually place two materials on the jig, manually align them and then fix them using relevant devices. After welding is completed, workers manually unload the materials. Each welding of an L-shaped frame requires repeating the above steps. Manual operation is rather troublesome, and the working time occupied by manual operation is relatively long, resulting in low overall efficiency. Summary of the Invention

Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0022] Embodiment 1 Please refer to Figure 1 - Figure 4, including an operating table 1, on which a mounting base 2 is installed. A first arm 3 is slidably connected to the mounting base 2, a second arm 4 is slidably connected to the first arm 3, and a welding head 5 is connected to the second arm 4. A driving device is provided between the mounting base 2 and the first arm 3, and the first arm 3 can move up and down on the mounting base 2. A driving device is provided between the second arm 4 and the first arm 3, and the second arm 4 can move left and right between the first arms 3. Therefore, the welding head 5 can adjust its position in four directions: up, down, left, and right for welding operations. A positioning block 6 is connected to the center position of the top surface of the operating table 1, and the mounting base 2 is located to the right of the positioning block 6. It further includes a feeding component 7 for pushing the materials to be welded. The feeding component 7 includes a first folding plate 77, which is installed on the operating table 1 through a bracket. A top plate 78 is installed on the operating table 1 through a bracket. The bottom surface of the top plate 78 is connected to the top surface of the first folding plate 77. A second folding plate 79 is slidably connected to the bottom surface of the top plate 78. The second folding plate 79 is located to the left of the first folding plate 77. The first folding plate 77 is located to the left of the positioning block 6. Openings are provided at the front and back of the gap between the first folding plate 77 and the second folding plate 79. The gap between the first folding plate 77 and the second folding plate 79 forms an L shape. Two stacks of materials are respectively inserted into the front and back openings of the gap between the first folding plate 77 and the second folding plate 79. After the two stacks of materials are pushed in place, the welding edges of two adjacent materials are attached together to form an L-shaped door and window frame. Through the cooperation of the first folding plate 77 and the second folding plate 79, the splicing of two batches of materials is completed. Compared with the manual splicing method one by one, the work efficiency is improved. Through the setting of the feeding component 7, the first folding plate 77 and the second folding plate 79 can complete the stacking and splicing of two batches of materials at one time through cooperation, reducing the operation steps of manual splicing by the staff and accelerating the work efficiency.

[0023] Further, please refer to Figure 1 - Figure 7, a push plate 76 is slidably connected to the top surface of the operating table 1. There is a gap between the first folding plate 77 and the second folding plate 79, and there is a gap between the bottom surfaces of the first folding plate 77 and the second folding plate 79 and the top surface of the operating table 1. The push plate 76 is located below the first folding plate 77 and the second folding plate 79. A sliding column 71 is slidably connected through the operating table 1. The top end of the sliding column 71 is connected to the first arm 3 through a bracket, and the bottom end of the sliding column 71 is connected to a cross bar 72. Two connecting rods 73 are respectively hinged at both ends of the cross bar 72. Two sliders 74 are slidably connected to the bottom surface of the operating table 1, and the two sliders 74 are respectively hinged to the ends of the two connecting rods 73 away from the cross bar 72. When the sliding column 71 drives the cross bar 72 to move downward, the cross bar 72 drives the two sliders 74 to move rightward through the two connecting rods 73. A sliding rod 75 is slidably connected to the bottom surface of the operating table 1. The outer walls at both ends of the sliding rod 75 are respectively connected to the two sliders 74 through springs. When the two sliders 74 move rightward, they drive the sliding rod 75 to move rightward through the springs. When the sliding rod 75 slides, the springs between the sliding rod 75 and the sliders 74 do not deform. A convex block is provided on the top surface of the sliding rod 75, and the convex block of the sliding rod 75 is connected to the bottom surface of the push plate 76. The convex block of the sliding rod 75 penetrates through the operating table 1. The two materials at the bottommost in the first folding plate 77 and the second folding plate 79 are located on the movement track of the push plate 76. When the push plate 76 moves rightward, it contacts the two materials and pushes them to the right. The push plate 76 finally pushes the two materials to the left side of the positioning block 6. At this time, the push plate 76 and the positioning block 6 clamp the two materials in the middle and keep them in a fitting state. At this time, after welding is completed, the push plate 76 resets to the left, and the materials in the first folding plate 77 and the second folding plate 79 fall, so that the two materials for the next welding fall to the right of the push plate 76, and then subsequent welding operations are carried out. Through the setting of the push plate 76, every time welding is performed, the push plate 76 can push the two bottommost materials to the left side of the positioning block 6 and cooperate with the positioning block 6 to clamp and position the materials, achieving the effect of automatic feeding and improving the automation level.

[0024] Furthermore, please refer to Figure 5 , a screw rod 711 is rotatably installed at the bottom of the top plate 78 through a bracket. The left side of the second folding plate 79 is connected with a nut plate 710. A threaded hole is provided on the nut plate 710, and the screw rod 711 is threadedly connected to the threaded hole of the nut plate 710. A rotating wheel is provided on the screw rod 711. When the staff rotates the screw rod 711 through the rotating wheel, the screw rod 711 drives the nut plate 710 to move leftward or rightward by using the threaded connection relationship. The nut plate 710 drives the second folding plate 79 to slide synchronously on the top plate 78, thus achieving the effect of adjusting the gap between the first folding plate 77 and the second folding plate 79, so as to match materials of different specifications. Through the cooperation of the screw rod 711 and the nut plate 710, the staff can adjust the distance between the first folding plate 77 and the second folding plate 79, so as to meet the splicing and pushing effects of various specifications of materials.

[0025] In addition, please refer to Figure 1 , Figure 8 – Figure 10 , the discharging assembly 8 is used to discharge the welded material. The discharging assembly 8 includes a mounting shaft 81. The mounting shaft 81 is rotatably mounted on the bottom surface of the operating table 1 through a bracket. Cam 82s are respectively connected to both ends of the mounting shaft 81. Grooved bars 83 are respectively connected to the right sides of the two sliders 74. A chute is provided on the grooved bar 83. The two cam 82s are respectively slidably connected to the chutes of the two grooved bars 83 through rollers. The chute on the grooved bar 83 is a connected straight groove and inclined groove. A connecting plate 84 is connected to the outer wall of the mounting shaft 81. A supporting plate 85 is connected to the connecting plate 84. An L-shaped groove is formed at the position of the operating table 1 to the left of the positioning block 6. The shape of the supporting plate 85 matches the L-shaped groove on the operating table 1. The supporting plate 85 fits in the L-shaped groove during movement. When the push plate 76 starts to move rightward, the two cam 82s drive the mounting shaft 81 to rotate clockwise. The mounting shaft 81 drives the supporting plate 85 to rotate clockwise through the connecting plate 84. When the two cam 82s rotate in place, the connecting plate 84 abuts against the bottom surface of the operating table 1, and the supporting plate 85 fits in the L-shaped groove of the operating table 1. Chamfers are provided at the edges of both the L-shaped groove and the supporting plate 85, and there is no movement interference during the fitting process. The supporting plate 85 provides bottom support for the material. After welding is completed, the mounting shaft 81 drives the supporting plate 85 to swing downward through the connecting plate 84. When the supporting plate 85 disengages from the L-shaped groove, the welded L-shaped door and window frame falls through the L-shaped groove below the tabletop of the operating table 1. Through the setting of the discharging assembly 8, the supporting plate 85 can turn up at the start of welding and fit with the L-shaped groove of the operating table 1 to support the material. After welding is completed, the supporting plate 85 can automatically turn down, enabling the L-shaped door and window frame to fall through the L-shaped groove, thereby leaving the operating table 1, achieving the effect of automatic discharging.

[0026] In addition to this, please refer to Figure 1 , Figure 10 – Figure 11, a bottom plate 86 is installed below the operating table 1 through a bracket. A sliding plate 87 is hinged on the bottom plate 86. The connecting plate 84 overlaps on the bottom plate 86 during movement. When the connecting plate 84 swings downward in place, it rests on the bottom plate 86. At this time, the support plate 85 and the sliding plate 87 are in the same plane. Workers can place a storage basket under the sliding plate 87. The falling L-shaped door and window frame slides into the storage basket through the support plate 85 and the sliding plate 87, achieving the effect of automatically conveying the welded L-shaped door and window frame into the storage basket. A crowbar 88 is rotatably installed below the operating table 1 through a bracket. The right end of the crowbar 88 is located on the movement track of the cross bar 72. The left end of the crowbar 88 is in sliding contact with the right side of the sliding plate 87. When the cross bar 72 moves downward, it drives the left end of the crowbar 88 to move upward by using the lever principle. When the left end of the crowbar 88 moves upward, it drives the sliding plate 87 to turn upward. The sliding plate 87 can promote the downward sliding of the L-shaped door and window frame above it by turning upward, avoiding the L-shaped door and window frame getting stuck on the sliding plate 87, thus causing a material blockage situation. Through the setting of the sliding plate 87, the falling materials slide into the storage basket below through the sliding plate 87 for storage, and the sliding plate 87 can automatically turn up at the start of each welding, thus avoiding some L-shaped door and window frames getting stuck on the sliding plate 87 during downward sliding, causing a material blockage situation.

[0027] It should be noted that please refer to Figure 1 , Figure 12 - Figure 14, the auxiliary positioning component 9 is used to assist in positioning the material. The auxiliary positioning component 9 includes two transmission belts 91. The two transmission belts 91 are installed on the operating table 1 through multiple pulleys. The two transmission belts 91 are mirror-imaged. The rotation directions of the two transmission belts 91 are opposite. The outer wall of the transmission belt 91 is connected with a lever 92 and a lever shaft 94. Two frame blocks 93 are slidably connected through the operating table 1. The bottom surfaces of the two frame blocks 93 are respectively connected to the top surfaces of the two slot rods 83. The two levers 92 are respectively located on the inner sides of the two frame blocks 93. Two square rods 96 are installed on the positioning block 6. A movable block 97 is slidably sleeved on the square rod 96. The bottom surface of the movable block 97 is connected with a pressure block 98 through a spring. The two pressure blocks 98 are mirror-imaged. Two rotating rods 99 are rotatably installed on the top surface of the positioning block 6. The ends of the two rotating rods 99 away from the positioning block 6 are respectively slidably hinged with the two movable blocks 97. A through groove is provided, and the two dial shafts 94 are slidably connected with the through grooves of the two rotating rods 99 respectively. When the two dial shafts 94 move in the direction away from each other, they can respectively drive the two rotating rods 99 to swing downward. When the rotating rod 99 swings downward, it can drive the movable block 97 to move downward. When the two materials move to the right, the two pressing blocks 98 move downward, and the two pressing blocks 98 are located above the L-shaped groove. When the two materials are against the positioning block 6, the two pressing blocks 98 contact the top surfaces of the two materials and apply pressure to the materials through the elastic force of the spring, so that the joint of the two materials is close to the support plate 85, avoiding the local warping of the joint of the materials during welding, resulting in reduced alignment of the materials, thereby affecting the welding quality. Through the setting of the auxiliary positioning component 9, when the two materials move to the welding operation position, the two pressing blocks 98 can move downward to press the ends of the joint of the two materials tightly, avoiding the warping of the splicing ends of the materials and causing uneven splicing, thereby affecting the welding quality.

[0028] It is worth mentioning that Figure 1 , Figure 12 - Figure 14, the front end and the rear end of the positioning block 6 are respectively connected with a base 910. A friction belt 911 is installed on the base 910 through two pulleys. A friction block 95 is connected to the outer wall of the transmission belt 91. The two friction belts 911 are respectively in contact with the two friction blocks 95. There is a large frictional force between the friction block 95 and the friction belt 911. A plurality of pulleys are arranged on the right side of the push plate 76, so that the frictional force between the push plate 76 and the material is relatively low, while the frictional force between the friction belt 911 and the material is relatively large. When two materials abut against the positioning block 6, the right sides of the two materials are respectively in contact with the left sides of the two friction belts 911. At this time, the push plate 76 and the two friction belts 911 clamp the two materials, and the rotation directions of the contact surfaces of the two friction belts 911 with the materials both face the welding joints of the materials. Therefore, when the two friction belts 911 rotate, they can push the two materials towards the middle, making the splicing parts of the two materials tightly abut against each other, preventing the two materials from shifting during movement and causing the splicing part to become loose, thus affecting the welding quality. Through the arrangement of the two friction belts 911, the two friction belts 911 can push the two materials tightly against each other, making the splicing parts of the two materials closely fit, avoiding large gaps at the splicing parts due to material displacement, thus affecting the welding quality.

[0029] With the above structure, the working principle of this case is that a driving device is provided between the mounting seat 2 and the No. 1 arm 3, and the No. 1 arm 3 can move up and down on the mounting seat 2, and a driving device is provided between the No. 2 arm 4 and the No. 1 arm 3, and the No. 2 arm 4 can move left and right between the No. 1 arm 3. Therefore, the welding head 5 can adjust the position in four directions of up, down, left and right to perform welding operations. Before welding, the staff will stack the two batches of materials that make up the L-shaped door and window frame together, and the gap between the first angle plate 77 and the second angle plate 79 is provided with openings at the front and back, and the two stacks of materials are respectively inserted into the front and back openings of the gap between the first angle plate 77 and the second angle plate 79. The gap forms an L shape. After the two stacks of materials are pushed into place, the welding edges of the two adjacent materials are fitted together to form an L-shaped door and window frame. The first angle plate 77 and the second angle plate 79 cooperate to complete the splicing of the two batches of materials. Compared with the manual splicing method one by one, the work efficiency is improved. When welding starts, arm 3 moves downward first. When arm 3 moves downward, it drives the slide column 71 downward through the bracket. The slide column 71 drives the cross bar 72 downward. The cross bar 72 drives the two sliders 74 to move right through the two connecting rods 73. The two sliders 74 drive the slide bar 75 to move right through the spring. When the slide bar 75 slides, the spring between the slide bar 75 and the slide bar 74 does not deform. When the slide bar 75 moves right, it drives the push plate 76 to move right through the protrusion, so that The push plate 76 starts to move rightward from the left side of the second angle plate 79, and the two lowest materials are located on the movement trajectory of the push plate 76. When moving rightward, the push plate 76 contacts the two materials and pushes them to the right. Subsequently, the top surface of the push plate 76 blocks the falling of other materials in the first angle plate 77 and the second angle plate 79 when sliding. The right side of the push plate 76 and the left side of the positioning block 6 are both set to a right angle shape matching the joint of the two materials. The push plate 76 eventually pushes the two materials to the left side of the positioning block 6. At this time, the push plate 76 and the positioning block 6 sandwich the two materials in the middle and keep them in a fitted state. Subsequently, the two sliders 74 continue to move rightward. At this time, the push plate 76 and the slide bar 75 stop moving rightward, and the elastic force between the slide bar 75 and the two sliders 74 The spring begins to stretch, so that the push plate 76 maintains the pressure on the material to the right, and can meet the pushing operation of materials of various specifications. When the two sliders 74 stop moving, the No. 1 arm 3 moves down to its position, and the No. 2 arm 4 drives the welding head 5 to move from right to left. The welding head 5 welds the joint of the two materials. After the welding is completed, the No. 2 arm 4 is reset, and the No. 1 arm 3 is reset to its initial state. The slide column 71 drives the two sliders 74 to move left and reset through the cross bar 72 and the two connecting rods 73. The two sliders 74 drive the push plate 76 to move left and reset through the slide bar 75. After the push plate 76 is reset, the materials in the first angle plate 77 and the second angle plate 79 fall, so that the two materials to be welded next fall on the right side of the push plate 76, and then the subsequent welding operation is carried out;When the staff rotates the screw rod 711 through the runner, the screw rod 711 drives the nut plate 710 to move left or right by means of the threaded connection relationship. The nut plate 710 drives the second folding angle plate 79 to slide synchronously on the top plate 78, thereby achieving the effect of adjusting the gap between the first folding angle plate 77 and the second folding angle plate 79, so as to match materials of different specifications. Through the setting of the feeding assembly 7, the first folding angle plate 77 and the second folding angle plate 79 can complete the stacking and splicing of two batches of materials at one time through cooperation, reducing the operation steps of manual splicing by the staff and improving the work efficiency. Through the setting of the push plate 76, every time welding is carried out, the push plate 76 can push the two lowest materials to the left side of the positioning block 6 and cooperate with the positioning block 6 to clamp and position the materials, achieving the effect of automatic feeding and improving the automation level. Through the cooperation of the screw rod 711 and the nut plate 710, the staff can adjust the distance between the first folding angle plate 77 and the second folding angle plate 79, so as to meet the splicing and pushing effects of materials of various specifications.;

[0030] The slide grooves on the slot rod 83 are connected straight grooves and inclined grooves. When the two sliders 74 move, the two slot rods 83 are driven to move synchronously. During the rightward movement of the slot rod 83, the inclined groove in the slide groove of the slot rod 83 first contacts the roller of the cam 82, causing the roller to slide upward along the inclined groove, thereby achieving the effect of the cam 82 rotating clockwise. When the cam 82 rotates clockwise to the right, the roller enters the straight groove. During the subsequent movement of the slot rod 83, the cam 82 remains stationary. When the slot rod 83 moves to the left, the cam 82 does not rotate first. After the roller enters the inclined groove, the cam 82 rotates counterclockwise to reset. Therefore, when the push plate 76 starts to move to the right, the two cams 82 drive the installation shaft 81 to rotate clockwise. The installation shaft 81 passes The connecting plate 84 drives the support plate 85 to rotate clockwise. When the two cams 82 rotate to the right position, the connecting plate 84 is attached to the bottom surface of the operating table 1, and the support plate 85 is attached to the L-shaped groove of the operating table 1. The edges of the L-shaped groove and the support plate 85 are chamfered, and there is no movement interference during the fitting process. Then the push plate 76 and the material continue to move right. When the material is against the positioning block 6, the material is located above the support plate 85, and the support plate 85 plays a role of bottom support for the material. When the welding is completed, as the push plate 76 moves to the left, the two cams 82 drive the installation shaft 81 to rotate counterclockwise, and the installation shaft 81 drives the support plate 85 to swing downward through the connecting plate 84. When the support plate 85 is out of the L-shaped groove, the welded L-shaped door and window frame falls to the Under the table top of the operating table 1, the connecting plate 84 swings downward into place and rests on the bottom plate 86. At this time, the supporting plate 85 and the sliding plate 87 are located in the same plane, and the staff can place a storage basket under the sliding plate 87. The falling L-shaped door and window frame slides into the storage basket through the supporting plate 85 and the sliding plate 87, so as to achieve the effect of automatically conveying the welded L-shaped door and window frame into the storage basket, and realize automatic material discharge. At the beginning of welding, the right end of the pry bar 88 is contacted and pushed downward during the downward movement of the cross bar 72, so that the pry bar 88 swings, and the left end of the pry bar 88 moves up. A through hole is provided on the bottom plate 86, and the left end of the pry bar 88 passes through the through hole and contacts the sliding plate 87. The hinge position of the sliding plate 87 and the bottom plate 86 is located at the sliding plate 8 7, therefore, when the left end of the pry bar 88 moves upward, the slide plate 87 is driven to flip upward. Since the L-shaped door and window frame may be stuck on the slide plate 87 during the sliding process, the slide plate 87 can promote the sliding of the L-shaped door and window frame above it by flipping upward, so as to avoid the L-shaped door and window frame being stuck on the slide plate 87, thereby causing material blocking. After the cross bar 72 moves upward, the slide plate 87 is reset by gravity, and the pry bar 88 is reset accordingly; through the setting of the discharge assembly 8, the support plate 85 can be flipped up at the beginning of welding and fit into the L-shaped groove of the operating table 1, so as to support the material. After the welding is completed, the support plate 85 can automatically flip down, so that the L-shaped door and window frame falls through the L-shaped groove, thereby leaving the operating table 1, achieving the effect of automatic discharge;Through the setting of the slide plate 87, the falling materials can slide onto the lower storage basket through the slide plate 87 for storage, and the slide plate 87 can automatically turn up at the start of each welding, thus avoiding the situation that some L-shaped door and window frames get stuck on the slide plate 87 during the downward slide, resulting in material blockage.

[0031] When the slot rod 83 moves, it drives the frame block 93 to move synchronously. The frame block 93 is set in a square shape. During the right movement of the frame block 93, the left inner wall of the frame block 93 contacts the lever 92 and drives the lever 92 to move right. When the frame block 93 moves to the left, its left inner wall contacts the lever 92 and drives the lever 92 to move left and reset. When the lever 92 moves, it drives the transmission belt 91 to rotate. The rotation directions of the two transmission belts 91 are opposite. Taking the transmission belt 91 located in the front as an example, the lever 92 moves to the right and drives the transmission belt 91 to rotate counterclockwise. The transmission belt 91 drives the shift shaft 94 and the friction block 95 to move to the left front along the front bevel of the positioning block 6. When moving, the shift shaft 94 slides to the left front along the through groove of the rotating rod 99, so that the shift shaft 94 gradually tilts the tilted rotating rod 99 When the two materials move to the right, the two pressing blocks 98 move downward, and the two pressing blocks 98 are located above the L-shaped groove. When the two materials are against the positioning block 6, the two pressing blocks 98 contact the top surface of the two materials and apply pressure to the materials through the elastic force of the spring, so that the joint of the two materials is close to the support plate 85, so as to avoid the local warping of the joint of the materials during welding, resulting in a decrease in the alignment of the materials, thereby affecting the welding quality. When the frame block 93 moves to the left, the lever 92 drives the transmission belt 91 to rotate clockwise, the lever shaft 94 is reset and drives the lever 99 to reset, and the lever 99 drives the movable block 97 to reset; with the friction at the front Taking block 95 and friction belt 911 as an example, when the friction block 95 moves to the left front, there is a large friction force between the friction block 95 and the friction belt 911, so that the friction belt 911 is driven by the friction block 95 to rotate clockwise on the base 910, and the rotation directions of the two friction belts 911 are also opposite. When the two materials are against the positioning block 6, the right sides of the two materials are respectively in contact with the left sides of the two friction belts 911. At this time, the push plate 76 and the two friction belts 911 clamp the two materials. A plurality of pulleys are arranged on the right side of the push plate 76, so that the friction force between the push plate 76 and the material is low, while the friction force between the friction belt 911 and the material is large, and the rotation directions of the contact surfaces of the two friction belts 911 and the material are both toward the material. The welding place, therefore, when the two friction belts 911 rotate, they can push the two materials toward the middle, so that the joint of the two materials is tightly pressed against each other, avoiding the displacement of the two materials during the movement, causing the joint to loosen, thereby affecting the welding quality; through the setting of the auxiliary positioning component 9, when the two materials move to the welding operation position, the two pressing blocks 98 can move down to press the ends of the joint of the two materials, avoiding the splicing ends of the materials from tilting up and causing uneven splicing, thereby affecting the welding quality; through the setting of the two friction belts 911, the two friction belts 911 can push the two materials against each other, so that the splicing of the two materials fits tightly, avoiding the large gap at the splicing due to the displacement of the materials, thereby affecting the welding quality.
