Description

Technical Field

[0001] This invention relates to the field of welding-related technologies, specifically to an intelligent welding production line for galvanized steel sheets. Background Technology

[0002] Galvanized steel sheet refers to steel sheet with a layer of zinc on its surface. Galvanizing is a commonly used, economical and effective method of rust prevention, and about half of the world's zinc production is used for this process.

[0003] Welding is usually one of the processing steps in the plate production line, and its main function is to weld and fix the plates together.

[0004] Regarding the welding direction, a welding device with workpiece surface grinding function has been disclosed through search, announcement number: CN221640144U;

[0005] Existing welding equipment has made significant improvements in solving problems such as weld slag and weld seams, but has not made targeted improvements in the jointing of plates during welding. The problem with plate jointing is that some plates will bend to a certain extent due to transportation and other reasons, mostly in the center of the plate, while the edge will hardly have this problem.

[0006] Existing docking equipment typically employs a docking method where two plates are placed on a flat surface and pushed to move relative to each other, thus docking. However, if the plates exhibit even slight bending, this docking method cannot ensure that the mating surfaces remain parallel during docking. Please refer to the accompanying drawings in the instruction manual. Figure 18 ;

[0007] Another solution is to use a robotic arm to grasp and dock, but this method is very expensive. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides an intelligent welding production line for galvanized steel sheets, which solves the problem of non-parallel butt joint surfaces during welding.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an intelligent welding production line for galvanized steel sheets, comprising a welding table and a support frame fixed to the welding table, and further comprising:

[0010] Two first support plates are fixed on both sides of the welding table. Two second conveyor rollers are rotatably installed at both ends of the two first support plates. The two second conveyor rollers are connected by a first conveyor belt. A second support plate is fixed between the two first support plates and is perpendicular to them. A first conveyor roller is rotatably installed at both ends of the second support plate. The two first conveyor rollers are connected by a second conveyor belt.

[0011] A welding mechanism is installed between the second conveyor belt and the first conveyor belt. The welding mechanism is used to weld the plates conveyed by the first conveyor belt and the second conveyor belt.

[0012] The docking mechanism is installed on the welding platform and located on both sides of the No. 2 conveyor belt and the No. 1 conveyor belt. The docking mechanism docks the plates conveyed by the No. 1 conveyor belt and the No. 2 conveyor belt at opposite ends, and welds the two No. 1 conveyor belts together by cooperating with the welding structure.

[0013] The unloading assembly is installed on the welding table and transports the welded plate onto the second conveyor belt.

[0014] Furthermore, the welding mechanism includes two mounting plates fixed to the welding table and the support frame. A first axial slide rod and a second axial slide rod are respectively fixed to opposite sides of the two mounting plates. The first axial slide rod fixes the two mounting plates together. The second axial slide rod is a separate unit and is located on the side of the welding table facing the second conveyor belt.

[0015] A guide rod and a guide rod are slidably mounted on the first axial slide rod and the second axial slide rod, respectively. A sliding component is slidably mounted on both the first guide rod and the second guide rod, and a welding torch for welding is fixed on the sliding component.

[0016] Both the first guide rod and the second guide rod have lead screws rotatably mounted on one side. Two sliding parts are threadedly engaged with the two lead screws respectively, and the two lead screws are connected by a driving component.

[0017] Furthermore, the driving component includes a limiting rod rotatably mounted between two mounting plates and located at the end. Two limiting sleeves are slidably mounted on the limiting rod. Follower frames are rotatably mounted on the two limiting sleeves. The two follower frames are respectively fixed to the first guide rod and the second guide rod. The two limiting sleeves are also connected to the two first threaded sleeves through a bevel gear set.

[0018] The limiting rod has multiple transmission bars fixed at equal intervals around its circumference, and these transmission bars slide in conjunction with the transmission grooves opened on the inner wall of the limiting sleeve.

[0019] A second motor is fixed on the support frame, and the output shaft of the second motor is connected to the limiting rod through a second transmission chain.

[0020] Furthermore, the unloading assembly includes a lifting frame slidably mounted on the welding table, the lifting frame being U-shaped, and two sets of conveyor wheels mounted on the top of the lifting frame;

[0021] A single set of conveyor wheels consists of multiple conveyor wheels arranged at equal intervals.

[0022] Furthermore, the docking mechanism includes two clamping members arranged symmetrically, with the two clamping members located between the two No. 1 conveyor belts;

[0023] The clamping component includes a second docking plate and a first docking plate, both of which have their centers of gravity located at the bottom.

[0024] Both sides of the No. 1 docking plate and the No. 2 docking plate are equipped with moving components, which are connected to two clamping components.

[0025] Both the No. 2 docking plate and the No. 1 docking plate have anti-slip layers on opposite sides.

[0026] Furthermore, the moving component includes four limiting plates, respectively located on both sides of the clamping component;

[0027] Each of the four limit plates has a first constraint slot and a second constraint slot.

[0028] Both the first constraint groove and the second constraint groove are movably installed with bushings. The bushing in the first constraint groove is rotatably sleeved on the rotating shaft of the first docking plate, and the bushing in the second constraint groove is rotatably sleeved on the rotating shaft of the first docking plate.

[0029] The rotating shafts of the No. 2 docking plate and the No. 1 docking plate are connected to the relatively moving parts installed on the limiting plate.

[0030] Furthermore, the first constraint groove and the second constraint groove include an inclined front part, a connecting part, and a horizontal part;

[0031] The distance between the front parts is greater than the distance between the horizontal parts, and the connecting part is located between the front and the horizontal parts.

[0032] Furthermore, a first extrusion plate and a second extrusion plate are fixed on the limiting plate and are arranged opposite to each other. The first extrusion plate and the second extrusion plate cooperate with the first docking plate and the second docking plate, respectively.

[0033] Both the No. 1 extrusion plate and the No. 2 extrusion plate are inclined.

[0034] Furthermore, the relative moving component includes a bidirectional lead screw rotatably mounted on the limiting plate, and both ends of the bidirectional lead screw are fitted with a No. 1 threaded sleeve that is threadedly engaged with it. The top and ground parts of the No. 1 threaded sleeve are fixed with sliding rods.

[0035] Both the No. 2 docking plate and the No. 1 docking plate have sliding sleeves coaxially mounted on their rotating shafts. The sliding sleeves are sleeved on the sliding rod and slidably connected to it.

[0036] A motor is fixed on the limiting plate, and the output shaft of the motor is connected to the bidirectional lead screw through the motor.

[0037] The present invention has the following beneficial effects:

[0038] 1. This intelligent welding production line for galvanized steel sheets uses two No. 1 conveyor belts to transport the steel sheets in a relative manner. After the two steel sheets are transported to the end of their stroke, the two No. 1 conveyor belts are connected and fixed by a docking mechanism.

[0039] Among them, the two docking plates No. 1 and No. 2 move relative to each other and clamp the plate during the relative movement. After the clamping is completed, the clamping and carrying movement is carried out.

[0040] The clamp is attached to the end of the plate, where the bending is minimal and can be corrected by clamping. Of course, plates without bending can also be joined normally.

[0041] Secondly, the docking implementation method and structure of the present invention are relatively simple, resulting in relatively low cost and high docking efficiency.

[0042] 2. This intelligent welding production line for galvanized steel sheets uses a welding mechanism to weld two connected No. 1 conveyor belts. The welding height can be adjusted to accommodate sheets of different thicknesses.

[0043] 3. This intelligent welding production line for galvanized steel sheets has a relatively high degree of automation. It can be connected with upstream and downstream equipment to achieve a complete assembly line operation and eliminate various dangers that may occur during processing.

[0044] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0067] The following is based on Figures 1-19 This invention describes an intelligent welding production line for galvanized steel sheets provided in an embodiment of the present invention.

[0068] Please see Figures 1-19This invention provides a technical solution: an intelligent welding production line for galvanized steel sheets, including a welding table 1 and a support frame 101 fixed on the welding table 1, and two first support plates fixed on both sides of the welding table 1. Second conveyor rollers 203 are rotatably mounted on both ends of the two first support plates, and the two second conveyor rollers 203 are connected by a first conveyor belt 2. A second support plate is fixed between the two first support plates and perpendicularly arranged thereto. First conveyor rollers 202 are rotatably mounted on both ends of the second support plate, and the two first conveyor rollers 202 are connected by a second conveyor belt 201. First drive motors are mounted on the first support plates, and the output shafts of the two first drive motors are coaxially fixed with the second conveyor rollers 203. When the first drive motors are working, they drive the two second conveyor rollers 203 to rotate relative to each other, thereby driving the two first conveyor belts 2 to convey relative to each other.

[0069] A second drive motor is installed on the second support plate. The output shaft of the second drive motor is coaxially fixed with the first conveyor roller 202 so that the first conveyor roller 202 is driven to rotate through the second drive motor, thereby driving the second conveyor belt 201 to transport.

[0070] The welding mechanism installed between the second conveyor belt 201 and the first conveyor belt 2 welds the plate 4 conveyed by the first conveyor belt 2 and the second conveyor belt 201.

[0071] The docking mechanism, installed on the welding table 1 and located on both sides of the second conveyor belt 201 and the first conveyor belt 2, docks the plates 4 conveyed by the first conveyor belt 2 and the second conveyor belt 201 at opposite ends, and welds the two first conveyor belts 2 together by cooperating with the welding structure.

[0072] The unloading assembly installed on the welding table 1 transports the welded plate 4 to the second conveyor belt 201.

[0073] In this embodiment of the invention, the two plates 4 to be welded are conveyed relative to each other by the first conveyor belt 2. When the plates 4 are conveyed to the designated position, the two plates 4 are connected by the docking mechanism so that the end faces of the two plates 4 are parallel while abutting. Finally, the two plates 4 are welded by the welding structure. Finally, the two plates 4 that have been welded are lifted by the unloading component and conveyed to the second conveyor belt 201. The two plates 4 that have been welded are conveyed to the next process by the second conveyor belt 201.

[0074] The designated position mentioned above refers to the point where plate 4 is conveyed to a position one-third of the way outside conveyor belt 2. Please refer to [link / reference needed]. Figure 17 ;

[0075] This invention includes a material feeding device, a welding device, a grinding device, a hole-opening device, and a palletizing device. The material feeding device feeds materials synchronously and intermittently onto two No. 1 conveyor belts 2. This invention is a welding device for the modified production line. After the welding work is completed by this invention, the two welded plates 4 are conveyed to the grinding device via the No. 2 conveyor belt 201. After grinding, they are conveyed to the hole-opening device and finally to the palletizing device to complete the process of the entire production line.

[0076] The welding mechanism includes two mounting plates 6 fixed on the welding table 1 and the support frame 101. A first axial slide rod 609 and a second axial slide rod 6010 are respectively fixed on opposite sides of the two mounting plates 6. The first axial slide rod 609 fixes the two mounting plates 6 together. The second axial slide rod 6010 is a separate part and is located on the side of the welding table 1 facing the second conveyor belt 201.

[0077] A guide rod 601 and a guide rod 602 are slidably mounted on the first axial slide rod 609 and the second axial slide rod 6010 respectively. A sliding element 605 is slidably mounted on both the first guide rod 601 and the second guide rod 602. A welding torch 603 for welding is fixed on the sliding element 605.

[0078] Both guide rod 601 and guide rod 602 have lead screws 604 rotatably mounted on one side. Two sliding parts 605 are threadedly engaged with the two lead screws 604 respectively, and the two lead screws 604 are connected by a driving component.

[0079] In this embodiment of the invention, both the first guide rod 601 and the second guide rod 602 are fixed to the conveying rod of the electric push rod installed on the welding table 1 and the support frame 101. The operation of the electric push rod drives the first guide rod 601 and the second guide rod 602 to move relative to or in opposite directions. The first axial slide rod 609 and the second axial slide rod 6010 provide guidance and limit for the first guide rod 601 and the second guide rod 602.

[0080] When the first guide rod 601 and the second guide rod 602 move relative to or in opposite directions, they drive the lead screw 604, the sliding member 605, and the welding torch 603 to move synchronously. When the driving component is working, it synchronously drives the two lead screws 604 to rotate, so that the sliding member 605 and the welding torch 603 can move axially along the first guide rod 601 through the threaded engagement between the lead screw 604 and the sliding member 605.

[0081] By describing the motion state, the two welding torches 603 were able to move relative to or in opposite directions, and the synchronous horizontal movement of the two welding torches 603 was also achieved. The effect of the relative movement of the two welding torches 603 is as follows:

[0082] 1. Applicable to plates of different thicknesses;

[0083] Second, when the docking mechanism completes the docking of the two plates 4, the moving of the plates 4 can prevent damage to the welding gun 603 caused by the dynamic plates 4.

[0084] The effect of the separate second axial slide bar 6010 is that when the welding work is completed and the material is unloaded by the unloading assembly, if the second axial slide bar 6010 is set in the same way as the first axial slide bar 609, it will prevent the welded plate 4 from moving onto the second conveyor belt 201.

[0085] It should also be noted that the electric actuator in this embodiment is not shown.

[0086] The driving component includes a limiting rod 608 rotatably mounted between two mounting plates 6 and located at the end. Two limiting sleeves 6012 are slidably mounted on the limiting rod 608. Follower frames 6013 are rotatably mounted on the two limiting sleeves 6012. The two follower frames 6013 are respectively fixed to the first guide rod 601 and the second guide rod 602. The two limiting sleeves 6012 are also connected to two first threaded sleeves 504 through a bevel gear set 6011. The bevel gear set 6011 includes two meshing bevel gears. The two bevel gears are coaxially fixed to the first threaded sleeve 504 and the limiting sleeve 6012, respectively.

[0087] The limiting rod 608 has multiple transmission bars fixed at equal intervals around its circumference, and these transmission bars slide in cooperation with the transmission groove opened on the inner wall of the limiting sleeve 6012.

[0088] A second motor 606 is fixed on the support frame 101, and the output shaft of the second motor 606 is connected to the limiting rod 608 through a second transmission chain 607.

[0089] In this embodiment of the invention, when the No. 2 motor 606 is working, its output shaft drives the limit rod 608 to rotate through the No. 2 transmission chain 607, so as to drive the two limit sleeves 6012 to rotate synchronously through the cooperation of the transmission bar and the transmission groove. When the limit sleeve 6012 rotates, the No. 1 threaded sleeve 504 is driven to rotate through the bevel gear set 6011.

[0090] When the first guide rod 601 and the second guide rod 602 move relative to or opposite to each other, the follower frame 6013 drives the limiting sleeve 6012 to slide axially on the limiting rod 608, so that the first guide rod 601 and the second guide rod 602 can be adjusted relative to or opposite to each other without losing drive.

[0091] It should be noted that the second motor 606 in this embodiment is a servo motor. Of course, stepper motors and DC motors can also be selected according to actual production needs, as long as the driving requirements are met. This invention does not impose specific limitations.

[0092] It should also be noted that the welding table 1 is provided with a slot 102 to provide space for the lower welding torch 603 to move when the two welding torches 603 move in opposite directions.

[0093] The unloading assembly includes a lifting frame 3 that is slidably mounted on the welding table 1. The lifting frame 3 is U-shaped and has two sets of conveyor wheels mounted on its top.

[0094] A single set of conveyor wheels includes multiple conveyor wheels 301 arranged at equal intervals.

[0095] In this embodiment of the invention, the first conveyor wheel 301 and the last conveyor wheel 301 are connected by a synchronous belt. A high-torque motor is installed inside the lifting frame 3. The output shaft of the high-torque motor is connected to the first conveyor wheel 301 or the last conveyor wheel 301 through a gear set. When the high-torque motor is working, its output shaft drives the first or last conveyor wheel 301 to rotate through the gear set, so that when one of the conveyor wheels 301 rotates, the other conveyor wheel 301 is driven to rotate through the synchronous belt, so that the two conveyor wheels 301 rotate synchronously.

[0096] An electric push rod (not shown in the figure) is also installed at the bottom of the lifting frame 3. The movable rod of the electric push rod is fixed to the lifting frame 3. When the electric push rod is working, it drives the lifting frame 3 to rise or fall. When the lifting frame 3 rises, it first abuts against the plate 4 through the conveyor wheel 301. Then, as the lifting frame 3 continues to rise, it lifts the plate 4. Then, the plate 4 is conveyed by the rotation of the conveyor wheel 301 to the second conveyor belt 201.

[0097] The docking mechanism includes two clamping components arranged symmetrically, which are located between two No. 1 conveyor belts 2;

[0098] The clamping component includes a second docking plate 5010 and a first docking plate 509, with the center of gravity of both the second docking plate 5010 and the first docking plate 509 located at the bottom.

[0099] Movable components are installed on both sides of the first docking plate 509 and the second docking plate 5010, and the movable components are connected to two clamping components; the shapes of the first docking plate 509 and the second docking plate 5010 include, but are not limited to, triangles or cones.

[0100] Both the No. 2 docking plate 5010 and the No. 1 docking plate 509 have anti-slip layers on their opposite sides.

[0101] In this embodiment of the invention, when the moving component is working, it first drives the second docking plate 5010 and the first docking plate 509 to move horizontally, and moves relative to each other during the horizontal movement. This relative movement clamps the plate 4, so that after the clamping of the plate 4 is completed, the two plate 4 are driven to move relative to each other until the ends of the two plate 4 abut.

[0102] In this embodiment, the fact that the centers of gravity of docking plate 5010 and docking plate 509 are both downward means that docking plate 5010 and docking plate 509 are rotatably connected to the moving component. This rotatable connection is in a free-rotating state, so that docking plate 5010 and docking plate 509, which are equipped with anti-slip layers, are always set relative to each other. Although docking plate 5010 and docking plate 509 may sway during the movement, their orientation will not deviate too much. The specific function of this is explained in detail in the moving component.

[0103] The moving component includes four limiting plates 5, which are located on both sides of the clamping component;

[0104] Each of the four limiting plates 5 has a first constraint groove 501 and a second constraint groove 502;

[0105] Both the first constraint groove 501 and the second constraint groove 502 are movably installed with bushings 5011. The bushing 5011 in the first constraint groove 501 is rotatably sleeved on the rotating shaft of the first docking plate 509, and the bushing 5011 in the second constraint groove 502 is rotatably sleeved on the rotating shaft of the first docking plate 509. The movable installation of the bushing 5011 means that the bushing 5011 can slide, roll, rotate, or arbitrarily combine along the path of the first constraint groove 501. The function of the bushing 5011 is to reduce the friction during sliding and to improve the smoothness of sliding.

[0106] The rotating shafts of the second docking plate 5010 and the first docking plate 509 are connected to the relatively moving parts installed on the limiting plate 5.

[0107] In this embodiment of the invention, the No. 2 docking plate 5010 and the No. 1 docking plate 509 on both sides are driven to move relative to each other by a relative moving component.

[0108] Since bushings 5011 are movably installed in both the first constraint groove 501 and the second constraint groove 502, and the second docking plate 5010 and the first docking plate 509 are rotatably installed in the bushings 5011, when the second docking plate 5010 and the first docking plate 509 move toward the other second docking plate 5010 and the first docking plate 509, the distance between the second docking plate 5010 and the first docking plate 509 is actually restricted by the first constraint groove 501 and the second constraint groove 502. This causes the relative distance between the second docking plates 5010 and the first docking plate 509 on both sides to gradually decrease, so that the plate 4 is clamped after the distance between them decreases to a certain distance, and then the plate 4 is clamped and moved horizontally.

[0109] The reason why the center of gravity of the No. 2 docking plate 5010 and the No. 1 docking plate 509 is downward is that when the No. 2 docking plate 5010 and the No. 1 docking plate 509 move along the path of the No. 1 constraint groove 501 and the No. 2 constraint groove 502, the side of the No. 2 docking plate 5010 with the anti-slip layer always faces downward, and the side of the No. 1 docking plate 509 with the anti-slip layer always faces upward, and the shaking during the process does not affect the clamping of the plate body 4.

[0110] The first constraint groove 501 and the second constraint groove 502 include a front part, a connecting part, and a horizontal part that are inclined.

[0111] The distance between the front parts is greater than the distance between the horizontal parts, and the connecting part is located between the front and the horizontal parts.

[0112] In this embodiment of the invention, the second constraint groove 502 and the first constraint groove 501 are mirror images of each other with their center point of distance. When the second docking plate 5010 slides in the first constraint groove 501, it is initially located at the front. As it moves, the distance between it and the first docking plate 509 gradually decreases. When the second docking plate 5010 moves to the connecting part, it clamps the plate 4 by cooperating with the first docking plate 509. Then, in subsequent movements, the distance between the first docking plate 509 and the second docking plate 5010 will not decrease or increase, but only move horizontally. Thus, the plate 4 is clamped by cooperating with the first docking plate 509 and the second docking plate 5010, so that the horizontal position of the two plates 4 is determined and they move relative to each other for docking.

[0113] The connecting part is actually used to smoothly connect the front and horizontal parts. When the second docking plate 5010 and the first docking plate 509 move to this position, the gap between them will decrease slightly. For example, if the thickness of the plate 4 is 2cm, and the distance between the second docking plate 5010 and the first docking plate 509 when they move to the connecting part is 2cm, the gap between the second docking plate 5010 and the first docking plate 509 will decrease to 1.9cm when they move to the horizontal part. Since the plate 4 is not clamped by enough force, the plate 4 will deform. At this time, the anti-slip layer on the second docking plate 5010 or the first docking plate 509 will deform, and this process will clamp the plate 4.

[0114] The technical effect achieved by the above description of the motion state is that the clamping, clamping and carrying of the plate 4, and docking of the two plates 4 can be realized by driving the two second docking plates 5010 and the first docking plate 509 to move relative to each other. The structure is simple, the efficiency is high, and the docking will not have any deviation.

[0115] The limiting plate 5 is fixed with a first extrusion plate 7 and a second extrusion plate 701 arranged opposite to each other. The first extrusion plate 7 and the second extrusion plate 701 respectively cooperate with the first docking plate 509 and the second docking plate 5010.

[0116] Both the first extrusion plate 7 and the second extrusion plate 701 are inclined.

[0117] In this embodiment of the invention, after the first docking plate 509 and the second docking plate 5010 clamp the plate 4, they move to the horizontal position of the first constraint groove 501 and the second constraint groove 502. The horizontal position is a horizontal movement so that the first docking plate 509 and the second docking plate 5010 gradually cooperate with the first extrusion plate 7 and the second extrusion plate 701. The first extrusion plate 7 and the second extrusion plate 701 apply extrusion force to the first docking plate 509 and the second docking plate 5010 to avoid small deformation after the first docking plate 509 and the second docking plate 5010 clamp the plate 4, which would result in incomplete clamping and extrusion of the plate 4. In other words, the deformation of the first docking plate 509 and the second docking plate 5010 would prevent the plate 4 from being properly corrected.

[0118] In this embodiment, after the first docking plate 509 and the second docking plate 5010 have clamped the plate body 4, pressure is applied to the first docking plate 509 and the second docking plate 5010 through cooperation with the first extrusion plate 7 and the second extrusion plate 701, so as to eliminate the deformation of the first docking plate 509 and the second docking plate 5010.

[0119] The relative moving component includes a bidirectional lead screw 503 rotatably mounted on the limiting plate 5. Both ends of the bidirectional lead screw 503 are fitted with a first threaded sleeve 504 that is threaded with it. The top and ground parts of the first threaded sleeve 504 are fixed with a sliding rod 506.

[0120] Sliding sleeves 505 are coaxially mounted on the rotating shafts of the second docking plate 5010 and the first docking plate 509. The sliding sleeves 505 are sleeved on the sliding rod 506 and slidably connected to it.

[0121] A first motor 507 is fixed on the limiting plate 5, and the output shaft of the first motor 507 is connected to the bidirectional lead screw 503 through the first motor 507.

[0122] In this embodiment of the invention, when the No. 1 motor 507 is working, its output shaft drives the bidirectional lead screw 503 to rotate through the No. 1 transmission chain 508. When the bidirectional lead screw 503 rotates, it drives the two No. 1 threaded sleeves 504 to move relative to each other through the threaded engagement with the two No. 1 threaded sleeves 504. When the No. 1 threaded sleeves 504 move, they drive the slide rod 506 to move synchronously, so that the slide rod 506 and the sliding sleeve 505 drive the No. 2 docking plate 5010 and the No. 1 docking plate 509 to move synchronously.

[0123] This causes the two No. 2 docking plates 5010 and the No. 1 docking plate 509 to move relative to each other. Since the sliding sleeve 505 and the sliding rod 506 are slidably connected, the relative movement of the two No. 2 docking plates 5010 and the No. 1 docking plate 509 is not affected when they move relative to each other.

[0124] During use (operation), the plate 4 is conveyed relative to each other by two No. 1 conveyor belts 2. After the plate 4 moves to the position indicated, the two plate 4 are aligned at the ends by the docking mechanism.

[0125] Then, the two plates 4 are welded and fixed together using a welding mechanism;

[0126] Finally, the welded plate 4 is lifted by the unloading assembly and conveyed onto the second conveyor belt 201.
