Description

Technical Field

[0001] The present application relates to the technical field of PPH wound storage tank production, and in particular to a PPH wound storage tank bottom plate production welding system. Background Art

[0002] PPH tank, the full name of which is high performance polypropylene tank, is a thermoplastic plastic product made by the polymerization of propylene monomer. It is also a type of large plastic storage tank with broad application prospects.

[0003] PPH tanks are mainly formed as a whole by spiral winding process, which makes the tanks have the characteristics of no welding and no leakage. In the production process, the tank body and the tank bottom are first made, and then the tank body and the tank bottom are welded inside and outside. However, due to the large size of some storage tanks, the size of the tank bottom is also large. However, it is difficult and costly to make a large circular tank bottom. Generally, two arched plates that can be spliced ​​into a circular plate are cut from a smaller square PPH plate; when splicing, the two arched plates are placed on the two welding tables of the machine body with the planes facing each other and the arcs facing each other, and then the planes of the two arched plates are heat-melted by the hot-melt welding plate. Finally, the two welding tables are moved to make the two arched plates close to each other and squeezed until they are cooled and formed. Then, the spliced ​​tank bottom can be taken out, and finally, the waste material overflowed from the hot melt at the weld of the two arched plates is scraped and polished.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: since two arch plates are cut out from a square plate, it is generally done manually and the cutting accuracy is low, resulting in uneven planes and curved surfaces of the arch plates. At the same time, since the arch plates are heavy, large errors and inconveniences in alignment will occur when the two arch plates are moved to the welding table and aligned. When the two arch plates need to be taken out after welding, the waste squeezed out during welding will also solidify and form, which will interfere with the staff in dragging out the welded arch plates. Summary of the invention

[0005] In order to improve the problem that the two arch plates are difficult to align before welding and difficult to remove after welding, the present application provides a PPH wrapped tank bottom plate production welding system.

[0006] The PPH winding tank bottom plate production welding system provided in this application adopts the following technical solutions:

[0007] The PPH winding tank bottom plate production welding system includes a machine body, two welding tables slidably connected to the machine body and a welding plate lifted and set on the machine body, wherein the welding plate is located between the two welding tables, and is characterized in that an alignment box is fixedly connected to the bottom of the welding plate, a crossbeam is fixedly connected to the machine body above each welding table, a plurality of hydraulic pressure plates are fixedly connected to the bottom of the crossbeam, a visual sensor is fixedly connected to the side of the crossbeam away from the welding plate, a controller electrically connected to the visual sensor and having a built-in Gaussian filter is fixedly connected to the machine body, an adjustment component for adjusting the position of the arch plate is arranged on the welding table, a cleaning component for cleaning waste overflowed from the arch plate is arranged on the machine body, and a feeding component for loading and unloading is also arranged on the machine body.

[0008] By adopting the above technical solution, two arched plates to be welded are placed on the welding table through the feeding assembly, and then the alignment box is raised, and the arched plate is moved so that the arched plate is close to the alignment box. At this time, the visual sensor scans the shape of the arched plate and feeds back to the controller. Since the peripheral side of the arched plate is uneven, the Gaussian filter in the controller filters out the noise received from the more convex parts of the peripheral wall of the arched plate, so that the final signal received by the controller is a smooth arched plate with the most concave part of the peripheral wall as the standard. The controller with the Gaussian filter is more accurate than the naked eye, and has lower cost and stronger real-time performance than contour detection plus fitting algorithm or deep learning method. The controller also fits the bisector of the arched plate after noise filtering and feeds back to the visual sensor. The controller adjusts the position of the arch plate by controlling the adjustment component to make the bisectors of the two arch plates relatively aligned. At this time, the pressure plate is lowered to fix the arch plate, and the welding plate is lowered until the arch plate is opposite to the welding plate. Then the two welding stations are close to each other, so that the arch plate squeezes the welding plate. The arch plate is affected by pressure and high temperature, and then the straight edge of the arch plate is melted; finally, the welding plate is lowered to make the two arch plates face each other without obstruction, and the two welding stations are adjusted to be close to each other again, so that the two arch plates are squeezed and fused with each other, and the cleaning component removes the waste at the fusion. When the two arch plates are cooled, they can be unloaded through the feeding component. The process is simple, the welding accuracy is high, and there is no waste interference at the fusion of the arch plates during unloading, so the unloading is more convenient.

[0009] Optionally, the adjustment component includes a lifting platform arranged in the body, a first driving belt arranged on the lifting platform, a plurality of balls rolling and embedded in the first driving belt, and a second driving belt arranged on the lifting platform, the first driving belt and the second driving belt are staggered with each other, the lifting platform, the first driving belt and the second driving belt are all electrically connected to the controller, when the lifting platform is raised to the highest point, the ball at the highest point is higher than the welding table, the upper surface of the second driving belt is tightly pressed against the bottom of the ball at the highest point, and the driving directions of the first driving belt and the second driving belt are perpendicular.

[0010] By adopting the above technical solution, when the arch plate needs to be adjusted, the lifting platform is raised, and when the first driving belt is turned on and the second driving belt is stationary, the rotation tangent direction of the ball and the arch plate at the point where they are in contact is parallel to the running direction of the upper surface of the second driving belt, and the moving direction of the ball is also parallel to the running direction of the upper surface of the second driving belt, thereby causing the arch plate to move along the moving direction of the ball; when the second driving belt is turned on and the first driving belt is stationary, the ball does not move, but the ball is driven by the second driving belt to rotate, that is, the rotation direction of the ball and the arch plate at the point where they are in contact is opposite to the driving direction of the upper surface of the second driving belt, and the controller controls the arch plate to move in multiple directions in the horizontal direction by controlling the opening and closing of the first driving belt and the second driving belt, so as to facilitate the mutual alignment of the two arch plates.

[0011] Optionally, the first driving belts have two belts, and the conveying direction of the first driving belts is perpendicular to the welding plate.

[0012] By adopting the above technical solution, the controller controls the running speed and direction of the two first drive belts, so that the speeds of the two first drive belts are different to control the arch plate to move in an arc, and even control the running directions of the two first drive belts to be opposite to each other to control the arch plate to rotate, thereby making the arch plate have more movement directions.

[0013] Optionally, the alignment box is made of a translucent material, a plurality of photosensitive sensors are arranged in two rows along the inner edge of the alignment box, the photosensitive sensors are fitted with the alignment box, and a plurality of lighting lamps facing the arch plate are arranged on the crossbeam.

[0014] By adopting the above technical solution, the light of the lighting lamp is irradiated on the alignment box and passes through the alignment box. Since the arch plate is in contact with the alignment box, the alignment box is darker below the arch plate and brighter above the arch plate. The photosensitive sensor determines the height of the arch plate by the degree of light. If there are debris on the welding table, it is easy to cause the heights of the two arch plates to be different. The photosensitive sensor will then feed back to the sensor to prompt the staff.

[0015] Optionally, the light emitted by the illuminating lamp is parallel light directed vertically downward, and a reflector with an angle of 45° to the soldering station is fixedly connected to one end of the pressure plate close to the alignment box, and the lowest end of the reflector is at the same height as the lowest end of the pressure plate, and the illuminating lamp shines on the lowest end of the reflector.

[0016] By adopting the above technical solution, the parallel light of the lighting lamp is irradiated on the reflector, so that the light is close to the surface of the bow plate. If the bow plate is warped, the light trajectory will change or be absorbed by the bow plate. Compared with conventional lighting lamps, it is difficult for conventional lighting lamps to make parallel light close to the surface of the bow plate, while the reflector structure is relatively simple and the cost is low.

[0017] Optionally, the reflectors on the two rows of pressure plates are arranged in a staggered manner, and a light-transmitting hole facing the reflector is provided on the pressure plate not equipped with the reflector.

[0018] By adopting the above technical solution, the parallel light reflected by the reflector passes through the light-transmitting hole opposite to it and is monitored in real time by the visual sensor. If the light path changes after passing through the light-transmitting hole, it means that the bow plate is bent, which in turn prompts the staff. The vertical alignment of the two bow plates is more accurate and low-cost through light detection.

[0019] Optionally, a heat insulation plate is fixedly connected to one end of the alignment box close to the inner top wall thereof, and an opaque partition plate is fixedly connected to the alignment box between two rows of the photosensitive sensors.

[0020] By adopting the above technical solution, the heat insulation board has a better heat insulation effect, so that the photosensitive sensor in the alignment box is less affected by the temperature of the welding plate, and the partition plate prevents the photosensitive sensor from being affected by the light emitted by the lighting lamp on its back.

[0021] Optionally, the cleaning assembly includes two lower pressure plates movably arranged in the machine body, an upper pressure plate lifted and lowered on the cross beam, a fixed plate fixedly connected under the lower pressure plate, a scraper arranged on the machine body and a driving member for driving the scraper to move, the lower pressure plate is located on a side of the fixed plate close to the welding plate and is provided with a plurality of discharge holes, and when the two lower pressure plates are pressed against each other, the upper surface of the lower pressure plate is flush with the welding table, and the fixed plate is pressed against the upper surface of the welding plate, the surfaces of the upper pressure plate, the lower pressure plate and the scraper are all made of Teflon material with extremely low adhesion to PPH and high temperature resistance, and a collecting bucket is placed at the end of the welding plate in the machine body.

[0022] By adopting the above technical scheme, after the two arched plates are hot-melted, the two lower pressure plates are moved to be flush with the welding table, and the two lower pressure plates are also pressed against each other, and the upper pressure plate is also moved down to be pressed against the arched plate, and then the two welding tables are driven close to each other to squeeze the two arched plates against each other, that is, the upper part of the weld of the two arched plates is pressed by the upper pressure plate, and the weld waste squeezed by the two arched plates is discharged from the discharge hole on the lower pressure plate. After the extrusion of the two arched plates is completed, the driving part drives the scraper to scrape the waste above the welding plate and remaining on the lower pressure plate into the collection bucket. After the two arched plates are cooled, the lower pressure plate and the upper pressure plate are returned to their original positions. At this time, there is less waste at both ends of the arched plates, which is convenient for dragging the arched plates to the feeding assembly for unloading and later grinding operations.

[0023] Optionally, the driving member is an electric rigid chain fixedly connected to the machine body, and an output end of the electric rigid chain is fixedly connected to the scraper.

[0024] By adopting the above technical solution, when the scraper is driven to perform scraping operations, the electric rigid chain is turned on to push or pull the scraper. After the electric rigid chain is contracted, it is smaller in size than the telescopic rod and has a higher rigidity when extended.

[0025] Optionally, the feeding assembly includes two L-shaped feeding rods hinged to the feeding end of the body and a hydraulic cylinder hinged to the body, and the output end of the hydraulic cylinder is fixedly connected to the feeding rods.

[0026] By adopting the above technical solution, when feeding is required, the hydraulic cylinder is extended to push the feeding rod to flip, and then the arc surface of the bow plate is placed downward on the feeding rod, and then the hydraulic cylinder is driven to contract to flip the feeding rod to be flush with the surface of the welding table.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the two arch plates need to be aligned before welding, the visual sensor scans the shape of the arch plate and feeds back to the controller. Since the circumference of the arch plate is uneven, the Gaussian filter in the controller filters out the noise received from the more convex parts of the circumferential wall of the arch plate, so that the final signal received by the controller is a smooth arch plate with the most concave part of the circumferential wall as the standard. The controller with Gaussian filter is more accurate than the naked eye, and has lower cost and stronger real-time performance than contour detection plus fitting algorithm or deep learning method. The controller also fits the bisector of the arch plate after noise filtering and feeds back to the visual sensor. The controller adjusts the position of the arch plate by controlling the adjustment component to make the bisectors of the two arch plates relatively aligned.

[0029] 2. The light of the lighting lamp shines on the reflector, so that the light is close to the surface of the arch plate. The parallel light reflected by the reflector passes through the light-transmitting hole opposite to it and is monitored in real time by the visual sensor. If the light path changes after passing through the light-transmitting hole, it means that the arch plate is bent, which prompts the staff; when the alignment box rises, the light enters the alignment box to the photosensitive sensor, and then the height of the arch plate is determined. If there are debris on the welding table, it is easy to cause the heights of the two arch plates to be different, and the angle of the light will change. The photosensitive sensor will feed back to the sensor to prompt the staff. Compared with conventional lighting lamps, conventional lighting lamps are difficult to make parallel light close to the surface of the arch plate, while the reflector structure is simpler and the cost is lower;

[0030] 3. After the two arch plates are hot-melted, the two lower pressure plates move to be flush with the welding table, and the two lower pressure plates are also pressed against each other, and the upper pressure plate also moves down to be pressed against the arch plate, and then the two welding tables are driven close to each other to squeeze the two arch plates against each other, that is, the upper part of the weld of the two arch plates is pressed by the upper pressure plate, and the weld waste squeezed by the two arch plates is discharged from the discharge hole on the lower pressure plate. After the extrusion of the two arch plates is completed, the electric rigid chain drives the scraper to scrape the waste above the welding plate and remaining on the lower pressure plate into the collection bucket. After the two arch plates are cooled, the lower and upper pressure plates are returned to their original positions. At this time, there is less waste at both ends of the arch plates, which is convenient for dragging the arch plates to the feeding assembly for unloading and later grinding operations.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The present application embodiment discloses a PPH winding tank bottom plate production welding system. Figure 1 , Figure 2 , Figure 3 and Figure 4 A PPH winding tank bottom plate production welding system includes a machine body 1, two welding tables 11 slidably connected to the machine body 1 and a welding plate 12 lifted and arranged on the machine body 1, the welding plate 12 is located between the two welding tables 11, and is characterized in that: an alignment box 13 is fixedly connected to the bottom of the welding plate 12, a crossbeam 14 is fixedly connected to the machine body 1 above each welding table 11, a plurality of hydraulic pressure plates 15 are fixedly connected to the bottom of the crossbeam 14, a visual sensor 21 is fixedly connected to the side of the crossbeam 14 away from the welding plate 12, a controller 22 electrically connected to the visual sensor 21 and having a built-in Gaussian filter is fixedly connected to the machine body 1, an adjustment component 3 for adjusting the position of the arch plate 9 is arranged on the welding table 11, a cleaning component for cleaning the waste overflowed from the arch plate 9 is arranged on the machine body 1, and a feeding component 5 for loading and unloading is also arranged on the machine body 1.

[0040] The feeding assembly 5 places two arched plates 9 to be welded on the welding table 11, then raises the alignment box 13, moves the arched plate 9 so that the arched plate 9 is close to the alignment box 13, and at this time the visual sensor 21 scans the shape of the arched plate 9 and feeds back to the controller 22. Since the peripheral side of the arched plate 9 is uneven, the Gaussian filter in the controller 22 filters out the noise received from the more convex parts of the peripheral wall of the arched plate 9, so that the final signal received by the controller 22 is a smooth arched plate 9 with the most concave part of the peripheral wall as the standard, and the controller 22 with the Gaussian filter is more accurate than the naked eye, and has lower cost and stronger real-time performance than contour detection plus fitting algorithm or deep learning method; the controller 22 also fits the bisector of the arched plate 9 after noise filtering and feeds back to the visual sensor 21, and the controller 2 The position of the arched plate 9 is adjusted by controlling the adjustment component 3 so that the bisectors of the two arched plates 9 are aligned. At this time, the pressure plate 15 is lowered to fix the arched plate 9, and the welding plate 12 is lowered until the arched plate 9 is directly opposite to the welding plate 12. Then, the two welding platforms 11 are brought close to each other so that the arched plate 9 squeezes the welding plate 12. The arched plate 9 is affected by pressure and high temperature, and then the straight edge of the arched plate 9 is melted. Finally, the welding plate 12 is lowered so that the two arched plates 9 are directly opposite to each other without any obstacles. The two welding platforms 11 are adjusted to be close to each other again so that the two arched plates 9 are squeezed and fused with each other. The cleaning component removes the waste at the fusion. When the two arched plates 9 are cooled, they can be unloaded through the feeding component 5. The process is simple, the welding accuracy is high, and there is no waste interference at the fusion of the arched plates 9 during unloading, so the unloading is more convenient.

[0041] Reference Figure 3 and Figure 4The adjustment component 3 includes a lifting platform 31 arranged in the body 1, a first driving belt 32 arranged on the lifting platform 31, a plurality of balls 33 rolling and embedded in the first driving belt 32, and a second driving belt 34 arranged on the lifting platform 31. There are two first driving belts 32, and the conveying direction of the first driving belt 32 is perpendicular to the welding plate 12. The first driving belt 32 and the second driving belt 34 are staggered with each other. The lifting platform 31, the first driving belt 32 and the second driving belt 34 are all electrically connected to the controller 22. When the lifting platform 31 is raised to the highest point, the ball 33 at the highest point is higher than the welding table 11, and the upper surface of the second driving belt 34 is tightly pressed against the bottom of the ball 33 at the highest point, and the driving directions of the first driving belt 32 and the second driving belt 34 are perpendicular.

[0042] When the arch plate 9 needs to be adjusted, the lifting platform 31 is raised, the first driving belt 32 is turned on, and the second driving belt 34 is stationary, the rotation tangent direction of the ball 33 and the arch plate 9 is parallel to the transmission direction of the upper surface of the second driving belt 34, and the moving direction of the ball 33 is also parallel to the transmission direction of the upper surface of the second driving belt 34, so that the arch plate 9 moves along the moving direction of the ball 33; when the second driving belt 34 is turned on and the first driving belt 32 is stationary, the ball 33 does not move, but the ball 33 is driven by the second driving belt The belt 34 is driven to rotate, that is, the rotation direction of the place where the ball 33 and the arch plate 9 are in contact is opposite to the running direction of the upper surface of the second driving belt 34. The controller 22 controls the opening and closing of the first driving belt 32 and the second driving belt 34 to control the arch plate 9 to move in multiple directions in the horizontal direction so that the two arch plates 9 are aligned with each other; when the controller 22 controls the two first driving belts 32 to run at different running speeds and directions, the arch plate 9 makes an arc motion or a rotation motion, so that the arch plate 9 has more movement directions.

[0043] Reference Figure 3 and Figure 5 and Figure 6 The alignment box 13 is made of translucent material, and a plurality of photosensors 81 are arranged in two rows along the inner edge of the alignment box 13. The photosensors 81 are fitted with the alignment box 13. A plurality of lighting lamps 82 facing the arch plate 9 are arranged on the crossbeam 14. The light emitted by the lighting lamps 82 is parallel light directed vertically downward. A reflector 151 with an angle of 45° to the welding platform 11 is fixedly connected to one end of the pressure plate 15 close to the alignment box 13, and the lowest end of the reflector 151 is at the same height as the lowest end of the pressure plate 15. The lighting lamp 82 irradiates the lowest end of the reflector 151. The reflectors 151 on the two rows of pressure plates 15 are arranged in an interlaced manner, and a light-transmitting hole 152 facing the reflector 151 is opened on the pressure plate 15 that is not equipped with the reflector 151; a heat insulation board 61 is fixedly connected to one end of the alignment box 13 close to its inner top wall, and an opaque partition board 62 is fixedly connected between the two rows of photosensors 81 in the alignment box 13.

[0044] The light of the lighting lamp 82 shines on the reflector 151, so that the light is close to the surface of the arch plate 9. The parallel light reflected by the reflector 151 passes through the light-transmitting hole 152 opposite to it and is monitored in real time by the visual sensor 21. If the light path changes after passing through the light-transmitting hole 152, it means that the arch plate 9 is bent, and then the staff is prompted; when the alignment box 13 is raised, the light enters the alignment box 13 to the photosensitive sensor 81, and then the height of the arch plate 9 is judged. If there are debris on the welding table 11, it is easy to cause the two arch plates to be bent. When the height of the plate 9 is different, the angle of the light will change, and the photosensor 81 will feed back to the sensor to prompt the staff. Compared with the conventional lighting lamp 82, the conventional lighting lamp 82 is difficult to make parallel light close to the surface of the bow plate 9, and the reflector 151 has a simpler structure and lower cost; the heat insulation board 61 has a better heat insulation effect, so that the photosensor 81 in the alignment box 13 is less affected by the temperature of the welding plate 12, and the partition plate 62 prevents the photosensor 81 from being affected by the light emitted by the lighting lamp 82 on its back.

[0045] Reference Figure 1 , Figure 5 and Figure 6 The cleaning component includes two lower pressing plates 41 movably arranged in the body 1, an upper pressing plate 42 lifted and arranged on the cross beam 14, a fixed plate 43 fixedly connected to the lower pressing plate 41, a scraper 44 arranged on the body 1 and a driving member for driving the scraper 44 to move. The lower pressing plate 41 is fixed to the body 1 by a two-way movable bracket composed of a screw rod and an electric push rod. The lower pressing plate 41 is located on one side of the fixed plate 43 close to the welding plate 12 and is provided with a plurality of discharge holes 431. When the two lower pressing plates 41 are pressed tightly against each other, the upper surface of the lower pressing plate 41 is flush with the welding platform 11, and the fixed plate 43 is pressed tightly against the upper surface of the welding plate 12. The surfaces of the upper pressing plate 42, the lower pressing plate 41 and the scraper 44 are all made of Teflon material with extremely low viscosity to PPH and high temperature resistance. A collecting bucket 7 is placed at the end of the welding plate 12 in the body 1. The driving member is an electric rigid chain 45 fixedly connected to the body 1, and the output end of the electric rigid chain 45 is fixedly connected to the scraper 44.

[0046] After the two arched plates 9 are hot-melted, the two lower pressing plates 41 move to be flush with the welding platform 11, and the two lower pressing plates 41 are also pressed against each other, and the upper pressing plate 42 also moves down to be pressed against the arched plate 9, and then the two welding platforms 11 are driven to approach each other so that the two arched plates 9 are squeezed against each other, that is, the upper part of the weld of the two arched plates 9 is pressed by the upper pressing plate 42, and the weld waste squeezed by the two arched plates 9 is discharged from the discharge hole 431 on the lower pressing plate 41. After the extrusion of the two arched plates 9 is completed, the electric rigid chain 45 drives the scraper 44 to scrape the waste above the welding plate 12 and remaining on the lower pressing plate 41 into the collecting bucket 7. After the two arched plates 9 are cooled, the lower pressing plate 41 and the upper pressing plate 42 are returned to their original positions. At this time, there is less waste at both ends of the arched plate 9, which is convenient for dragging the arched plate 9 to the feeding assembly 5 for unloading and later grinding operations.

[0047] Reference Figure 3 The feeding assembly 5 includes two L-shaped feeding rods 51 hinged at the feeding end of the body 1 and a hydraulic cylinder 52 hinged on the body 1, and the output end of the hydraulic cylinder 52 is fixedly connected to the feeding rod 51. When feeding is required, the hydraulic cylinder 52 is extended to push the feeding rod 51 to flip, and then the arc surface of the arch plate 9 is placed downward on the feeding rod 51, and then the hydraulic cylinder 52 is driven to contract, so that the feeding rod 51 is flipped to be flush with the surface of the welding table 11.

[0048] The implementation principle of the PPH winding tank bottom plate production welding system of the embodiment of the present application is as follows: the arch plate 9 is placed on the feeding rod 51, the feeding rod 51 is rotated to make the arch plate 9 to be welded in a horizontal state, and then the arch plate 9 is pushed onto the welding table 11 and the first driving belt 32 assists the movement of the arch plate 9;

[0049] The visual sensor 21 scans the shape of the arch plate 9 and feeds it back to the controller 22. The Gaussian filter in the controller 22 filters out the noise received from the more convex parts of the peripheral wall of the arch plate 9, so that the final signal received by the controller 22 is a smooth arch plate 9 with the most concave part of the peripheral wall as the standard. The controller 22 fits the bisector of the arch plate 9 after noise filtering and feeds it back to the visual sensor 21. The controller 22 adjusts the position of the arch plate 9 through the adjustment component 3, so that the bisectors of the two arch plates 9 are aligned, that is, the position of the arch plate 9 is adjusted by adjusting the running direction and running speed of the two first drive belts 32 and the one second drive belt 34;

[0050] Then, the pressure plate 15 is lowered to fix the arch plate 9, and the light of the illuminating lamp 82 is irradiated on the reflector 151, so that the light is close to the surface of the arch plate 9. The parallel light reflected by the reflector 151 passes through the light-transmitting hole 152 opposite to it, and is monitored in real time by the visual sensor 21. If the light path changes after passing through the light-transmitting hole 152, it means that the arch plate 9 is bent, and then the staff is prompted. Then, the alignment box is raised, and the light enters the alignment box 13 to the photosensitive sensor 81, and then the height of the arch plate 9 is judged. If there are debris on the welding table 11, it is easy to cause the heights of the two arch plates 9 to be different. The angle of the light will change, and the photosensitive sensor 81 will feed back to the sensor to prompt the staff;

[0051] Then, the welding plate 12 is lowered until the arch plate 9 is directly opposite to the welding plate 12, the two lower pressing plates 41 are moved to be flush with the welding platform 11, and the two lower pressing plates 41 are also pressed against each other, and the upper pressing plate 42 is also moved down to be pressed against the arch plate 9, and then the two welding platforms 11 are driven to approach each other so that the two arch plates 9 are squeezed against each other, that is, the upper part of the weld seam of the two arch plates 9 is pressed by the upper pressing plate 42, and the weld waste squeezed by the two arch plates 9 is discharged from the discharge hole 431 on the lower pressing plate 41. After the squeezing of the two arch plates 9 is completed, the electric rigid chain 45 drives the scraper 44 to scrape the waste above the welding plate 12 and remaining on the lower pressing plate 41 into the collection bucket 7. After the two arch plates 9 are cooled, the lower pressing plate 41 and the upper pressing plate 42 are returned to their original positions;
