Description

Technical Field

[0001] This invention relates to the field of barrel welding equipment technology, and in particular to a feeding, conveying, welding and unloading device for barrel plate welding. Background Technology

[0002] Metal drums are a type of packaging container formed by rolling and welding metal sheets. They are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrument and meter packaging, industrial product packaging, and military packaging.

[0003] In the existing metal drum manufacturing industry, to address environmental protection and production cost issues, coated drums have emerged on the market. These drums have a thin film applied to their inner and outer surfaces for surface treatment. Currently, most welding in coated drum production uses traditional methods. The production process involves first applying a coating layer to both the inner and outer surfaces of a flat metal plate, then milling or edge-trimming the ends to remove the coating layer, finally rolling the plate into a circle, welding the milled ends, and then repairing the weld with additional coating. In recent years, laser welding has gained widespread use due to its significant advantages—low heat input, high welding speed, small heat-affected zone, and minimal thermal deformation. However, there are currently very few laser welding machines specifically designed for welding metal drums on the market.

[0004] On the other hand, the two ends of the coated barrel need to be very close during welding; if they are more than 20 micrometers (0.2 mm) apart, the weld will fall off. This is especially true when the thickness of the coated barrel plate is about 1 mm, which places high demands on the precision of the entire welding device. In the existing technology, a laser welding machine of several hundred watts can generally weld two coated barrels per minute. How to develop an automated welding device with high positioning accuracy before welding, high overall welding efficiency, and high cost performance is an urgent problem to be solved. After searching, no technical solutions that are the same as or similar to this invention were found. Summary of the Invention

[0021] The top surfaces of the fixed seat and the moving seat are adjacent to each other and are flat surfaces. The top surfaces of the fixed seat and the moving seat, except for the flat surfaces, are curved surfaces. A groove parallel to the central axis of the rolled cylindrical plate is formed at the junction of the two flat surfaces. Each lower roller group includes a lower left roller, a lower right roller, and a lower roller, which are in the shape of an isosceles triangle. The upper left roller group and the upper right roller group are a row of roller groups whose length direction is parallel to the central axis of the rolled cylindrical plate. With the central axis of the rolled cylindrical plate as the viewing angle, the upper left roller group, the upper right roller group, the lower left roller, and the lower right roller are symmetrical vertically and horizontally within the rolled cylindrical plate.

[0022] The lower ends of the first positioning plate and the second positioning plate are both vertically arranged cuboids. The first positioning plate and the second positioning plate are arranged adjacent to each other in the left and right direction, and in the initial state, the lower end face of the first positioning plate is higher than the lower end face of the second positioning plate. The height alignment mechanism is located on the front side of the moving direction of the rolled cylindrical plate, and its structure includes a baffle and a baffle driving component for driving the baffle to rise and fall. The clamping mechanism includes a first clamping mechanism arranged on the same side as the moving base module and a second clamping mechanism arranged on the same side as the fixed base. The first clamping mechanism and the second clamping mechanism are arranged symmetrically on the left and right.

[0023] The number of laser welding heads is two, and the laser welding head drive includes two laser welding head cylinders connected to the two laser welding heads, and an electric cylinder that drives the two laser welding head cylinders to reciprocate in the same direction along the gap between the two ends to be welded.

[0024] Preferably, the barrel conveying mechanism includes a feeding frame, a plurality of feeding rollers arranged parallel to each other on the feeding frame, a feeding roller drive unit for driving the plurality of feeding rollers to rotate, and a plurality of feeding rollers arranged side by side at the upper ends of the plurality of feeding rollers along the barrel conveying direction; and limiting posts for limiting the barrel on both sides of the plurality of feeding rollers are fixedly provided.

[0029] Preferably, the transfer mechanism pushes the rolled cylindrical plate on the guide support mechanism to the positioning mechanism in a straight line, and the transition section between the guide support mechanism and the positioning mechanism is provided with a V-shaped guide groove to guide the two ends to be welded.

[0030] Compared with the prior art, the advantages of the present invention are:

[0031] (1) The feeding mechanism of the present invention completes the action of feeding flat plate to roll plate by setting up a barrel plate conveying mechanism, a three-roller rolling mechanism and a guide support mechanism. The position of the side roller is adjusted by the adjustment mechanism. The screw lift and the side roller cylinder fix the side roller, which plays a good role in fixing the side roller. It is easy to operate and has a high degree of automation.

[0032] (3) The welding mechanism of the present invention includes a positioning mechanism and a welding assembly for welding the positioned rolled cylindrical barrel plate; the positioning mechanism uses a clamping mechanism, a height alignment mechanism, and a thickness alignment mechanism to align and position the two ends to be welded. The clamping mechanism keeps the rolled cylindrical barrel plate rolled while bringing the two ends to be welded closer together. The height alignment mechanism aligns the rolled cylindrical barrel plate in its height direction (i.e., the axial direction of the rolled cylindrical barrel plate). The thickness alignment mechanism aligns the two ends to be welded vertically upward and downward (i.e., the wall thickness of the barrel body is aligned after welding), thereby improving the alignment accuracy between the two ends to be welded. In the fixed pressure plate assembly of the thickness alignment mechanism, a number of first fixed pressure plates and a number of second fixed pressure plates are arranged side by side along the axial direction of the rolled cylindrical barrel plate. The number of first fixed pressure plates and the number of second fixed pressure plates are arranged in segments and simultaneously perform downward pressing action. Compared with two whole plates directly pressing on the two ends to be welded, the segmented simultaneous downward pressing has the following advantages: first, the power is more dispersed; second, the force on the two ends to be welded is more uniform, avoiding the problems of hollowness and unevenness.

[0033] (4) In the welding mechanism of the present invention, the number of laser welding heads is two. In one welding stroke, each laser welding head only needs to weld half the length of the weld gap to be welded on a rolled barrel plate, thereby improving the welding efficiency of the rolled barrel plate.

[0034] (5) In one working cycle, the feeding mechanism and the welding mechanism operate at the same time, and the transfer mechanism and the unloading mechanism operate at the same time. That is, while the feeding mechanism is feeding and rolling, the welding mechanism positions and welds the rolled barrel plate that was transported by the transfer mechanism in the previous working cycle. While the unloading mechanism moves the welded barrel body out of the welding mechanism, the transfer mechanism transports the rolled barrel plate into the welding mechanism, which greatly improves the working efficiency of the whole device.

[0065] The present invention will be further described in detail below with reference to specific embodiments:

[0066] In the description of the invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0067] like Figure 1-2 As shown, a feeding, conveying, welding and unloading device for barrel plate welding includes a feeding mechanism 1, a conveying mechanism 2, a welding mechanism 3, and an unloading mechanism 4. In this embodiment, the feeding mechanism 1, the conveying mechanism 2, the welding mechanism 3, and the unloading mechanism 4 are all fixed on the frame 01. The outermost ring of each roller is made of rubber to protect the material and the finished product.

[0068] Feeding mechanism 1

[0069] like Figure 3 , 4 As shown in Figures 5, 8, and 9, the feeding mechanism 1 includes a barrel plate conveying mechanism 11 for flat barrel plates, a three-roller rolling mechanism 12 disposed at the conveying end of the barrel plate conveying mechanism 11, and a guide support mechanism 13 disposed directly below the three-roller rolling mechanism 12 to guide and support the barrel plate that has rolled up after passing through the three-roller rolling mechanism 12. The rolled barrel plate on the guide support mechanism 13 is horizontally inverted, and its two ends are two ends to be welded, and the two ends to be welded are located at the upper end of the horizontally inverted rolled barrel plate.

[0070] like Figure 3 As shown, the drum plate conveying mechanism 11 includes a feeding frame 111, a plurality of feeding rollers 112 arranged parallel to the feeding frame 111, and a feeding roller 112 driving member for driving the plurality of feeding rollers 112 to rotate. In this embodiment, the feeding roller 112 driving member is a motor connected to the upper roller 121 in the three-roller rolling mechanism 12 described below, that is, the plurality of feeding rollers 112 and the upper roller 121 share a motor. The motor and the plurality of feeding rollers 112 are connected by a synchronous belt and a synchronous pulley. The transmission structure of the synchronous belt and the synchronous pulley is not shown in the figure. The upper ends of the plurality of feeding rollers 112 are provided with a plurality of feeding rollers 113 arranged side by side along the drum plate conveying direction. Limiting posts 114 are fixed on both sides of the plurality of feeding rollers 112 to limit the sides of the drum plate. The limiting posts 114 play a limiting and guiding role in the conveying of the drum plate.

[0071] like Figure 4 , 8As shown in Figure 9, the three-roller winding mechanism 12 includes an upper roller 121, a lower roller 122 meshing with the upper roller 121, a side roller 123 connected to the upper roller 121 via another gear transmission, and a three-roller drive unit that drives the upper roller 121 and the lower roller 122 to rotate. In this embodiment, the rotation of the upper roller 121 drives the lower roller 122 to rotate, and the three-roller drive unit is a motor that is transmissionally connected to the upper roller 121. The upper roller 121 and the lower roller 122 clamp the barrel plate, and the central axis of the upper roller 121, the lower roller 122, and the side roller 123 is... The lines are perpendicular to the material feeding direction of the drum plate; the side roller 123 is set on the upper roller 121 and the lower roller 122 is located on the discharge side, and the position of the side roller 123 can be adjusted by the adjustment mechanism 124; specifically, the adjustment mechanism 124 includes connecting plates 1241 hinged to both sides of the upper roller 121, and a side roller cylinder 1242 hinged to the connecting plates 1241. The other end of the side roller cylinder 1242 is hinged to a fixed plate fixed on the frame, and the side roller 123 is fixed on the connecting plate 1241; In this embodiment, there are two connecting plates 1241, and a fixed plate 1243 is fixed between the two connecting plates 1241. A screw jack 1244 is also provided on the side of the adjusting mechanism 124. Specifically, the screw jack 1244 is positioned above the fixed plate 1243, and the screw of the screw jack 1244 abuts against the fixed plate 1243. During use, the position of the side roller 123 is adjusted (i.e., the curvature is adjusted) using the side roller cylinder 1242. After adjusting the curvature, due to… The upper roller 121 is fixed, the other end of the side roller cylinder 1242 is hinged to a fixed plate fixed on the frame, the connecting plate 1241 is hinged to the push rod of the cylinder, the side roller 123 is fixed, and then the screw of the screw jack 1244 abuts against the fixed plate 1243. The side roller cylinder 1242 plays the role of tightening the side roller 123. The screw jack 1244 and the side roller cylinder 1242 together fix the side roller 123, improving the rolling accuracy. The side roller 123 has the dual functions of pre-bending and rolling.

[0072] In this embodiment, as Figure 4 , 8 As shown, the upper roller 121 and the lower roller 122 are vertically fixed on the crossbeam 14 with an I-shaped cross section. The two sides of the crossbeam 14 are grooved to accommodate the two ends of the drum plate after it is rolled. The I-shaped crossbeam 14 plays a role in positioning and guiding the drum plate during the rolling process and when it is pushed to the next work station by the transfer mechanism 2. The crossbeam 14 is also equipped with a protective plate 15 at the discharge point of the lower roller 122.

[0073] The flat barrel plate is deformed and rolled into a cylindrical shape after being rolled by the three-roller rolling mechanism 12, and is referred to as the rolled barrel plate. The rolled barrel plate is horizontally inverted, and its two ends are two ends to be welded, and the two ends to be welded are located at the upper end of the horizontally inverted rolled barrel plate.

[0074] The guide support mechanism 13 includes a segmented guide plate assembly 131 and a plurality of support rollers 132 disposed below the rolled cylindrical plate. The positions of the guide plate assembly 131 and the plurality of support rollers 132 in the guide support mechanism 13 are matched with the shape of the cylindrical plate during and after rolling, and together form the forward passage during the rolling process of the cylindrical plate. The guide plate assembly 131 consists of a plurality of arc-shaped guide plates 1311 that are fixedly disposed.

[0075] Transfer Agency 2

[0076] like Figure 2-7 As shown, after the rolling is completed, the transfer mechanism 2 pushes the rolled cylindrical plate on the guide support mechanism 13 along a straight line to the positioning mechanism 31; the transfer mechanism 2 includes a pushing component that pushes the rolled cylindrical plate on the guide support mechanism 13 to the welding assembly 32, and a spreading component 22 disposed at the welding assembly 32 and cooperating with the pushing component for conveying; as shown Figure 6 , 7 As shown, the expansion component 22 acts on the inner wall of the rolled cylindrical plate, so that the two ends to be welded are not overlapping.

[0077] The pushing component is a belt conveyor assembly 21, which includes a driving roller 211, a driven roller 212, a belt 213 sleeved between the driving roller 211 and the driven roller 212, a pushing member 214 fixed on the belt 213, and a pushing drive member that is connected to the driving roller 211. In this embodiment, the pushing drive member is a motor. The pushing member 214 includes a frame 2141 fixedly connected to the belt 213 and a plurality of transfer push plates 2412 disposed on the frame 2141. The plurality of transfer push plates 2412 are disposed in the gaps between the guide plates 1311. The plurality of transfer push plates 2412 are four circular plates. The four circular plates are disposed in the gaps between the guide plates 1311. This arrangement saves device space and has a compact structure. In this embodiment, the frame 2141 is also slidably connected to the base plate through a slider and a linear guide rail, which ensures the accuracy of pushing the rolled cylindrical plate to the positioning mechanism 31.

[0078] like Figure 6 , 7As shown, the spreading assembly 22 includes an upper spreading assembly 22 that operates simultaneously and a lower spreading assembly 22 that operates sequentially; the upper spreading assembly 22 includes a left upper spreading module 221 and a right upper spreading module 222 that are symmetrically arranged; the left upper spreading module 22 includes a left upper roller assembly 2211 and a left upper spreading drive member 2212 that drives the left upper roller assembly 2211 to adhere to or separate from the inner wall of the rolled cylindrical plate; the right upper spreading module 22 includes a right upper roller assembly 2221 and a drive member 2221 that drives the right upper roller assembly 2221. The upper right side opening drive 2222 is attached to or separated from the inner wall of the rolled cylindrical plate; the lower opening assembly 22 includes a plurality of lower opening modules 223 arranged in parallel along the axial direction of the rolled cylindrical plate; each lower opening module 223 includes a lower roller assembly 2231 and a lower opening drive 2232 that drives the entire lower roller assembly 2231 to be attached to or separated from the inner wall of the rolled cylindrical plate; in this embodiment, the upper left side opening drive 2212, the upper right side opening drive 2222, and the lower opening drive 2232 are all cylinders.

[0079] Each lower roller assembly 2231 includes a lower left roller 2231a, a lower right roller 2231b, and a lower roller 2231c, all forming an isosceles triangle. The upper left roller assembly 2211 and the upper right roller assembly 2221 are both rows of rollers whose length direction is parallel to the central axis of the rolled cylindrical plate. Viewed from the central axis of the rolled cylindrical plate, the upper left roller assembly 2211 and the upper right roller assembly 2221 are symmetrical vertically and horizontally within the rolled cylindrical plate, ensuring uniform spreading force on the rolled cylindrical plate. The spreading assembly 22 ensures that the two ends of the rolled cylindrical plate to be welded are not overlapping during the transfer mechanism's transport to the guide support mechanism 13, improving the overall efficiency of the device. It also facilitates pre-welding positioning by the next welding mechanism 3, thereby improving welding accuracy.

[0084] The positioning mechanism 31 includes a support part for supporting the rolled cylindrical plate, a clamping mechanism 312 provided on both sides of the rolled cylindrical plate, a height alignment mechanism 313 that aligns the two ends to be welded in the axial direction of the rolled cylindrical plate, and a thickness alignment mechanism 314 that aligns the two ends to be welded in the vertical direction.

[0085] The support part is a base 311, and several rollers are provided on the base 311 along the axial direction of the rolled cylindrical plate. The support part provides support and transportation functions for the rolled cylindrical plate.

[0086] The clamping mechanism 312 includes a first clamping mechanism disposed on the same side as the moving base module and a second clamping mechanism disposed on the same side as the fixed base 3143. The first clamping mechanism and the second clamping mechanism are symmetrically arranged on the left and right sides. The first clamping mechanism and the second clamping mechanism respectively include a first arc-shaped clamping member 3121 and a second arc-shaped clamping member 3123 that match the shape of the rolled cylindrical plate, and a first clamping member driving member 3122 and a second clamping member driving member 3123 that drive the first arc-shaped clamping member 3121 and the second arc-shaped clamping member 3123 to move horizontally.

[0087] The height alignment mechanism 313 is located on the front side of the rolling drum plate in the direction of movement. Its structure includes a baffle 3131 and a baffle drive member 3132 that drives the baffle 3131 to rise and fall. The height alignment mechanism 313 aligns the rolling drum plate in its height direction (i.e., the axial direction of the rolling drum plate).

[0088] The thickness alignment mechanism 314 includes a positioning seat assembly disposed directly below the two ends to be welded, a positioning pressure plate assembly and a fixing pressure plate assembly disposed above the two ends to be welded and cooperating with the positioning seat assembly.

[0089] The positioning seat assembly includes a movable seat module for lifting and lowering and a fixed seat 3143, which are positioned horizontally. The movable seat module includes a movable seat 3141 and a movable seat drive component 3142 for lifting and lowering the movable seat 3141. The top surface of the fixed seat 3143 and the adjacent portion of the top surface of the movable seat 3141 are both flat surfaces 3144. Except for the flat surfaces 3144, the top surfaces of the fixed seat 3143 and the movable seat 3141 are all curved surfaces. The flat surfaces 3144 facilitate the thickness alignment of the two ends to be welded and the welding of the laser welding head 321. The curved surfaces and the rolled shape The inner walls of the barrel plate are matched; a groove 3145 parallel to the central axis of the rolled barrel plate is opened at the junction of the two flat surfaces 3144. In this embodiment, the width of the groove 3145 is 5 mm. The groove 3145 can accommodate the welding slag during welding by the laser welding head 321. The internal space of the groove 3145 is connected to the air blowing device. Specifically, the fixed seat 3143 and the moving seat 3141 are provided with through holes, which are connected to the air blowing device. The through holes and the groove 3145 are connected by opening several air holes. The air blowing device blows away the welding slag in the groove 3145.

[0090] The positioning plate assembly includes a first positioning plate drive module that cooperates with the moving base module and a second positioning plate drive module that cooperates with the fixed base 3143. The first and second positioning plate drive modules are connected to an oblique drive component 3155 that drives them to move obliquely back and forth as a whole towards a working position directly above the two ends to be welded. The first positioning plate drive module includes a first positioning plate 3146 whose length direction is parallel to the central axis of the rolled cylindrical plate and a first positioning plate drive component 3147 that drives the first positioning plate 3146 to move vertically up and down. The second positioning plate drive module includes a second positioning plate 3148 whose length direction is parallel to the central axis of the rolled cylindrical plate and a second positioning plate drive component 3148 that drives the second positioning plate 3148 to move vertically up and down. 149; The lower ends of the first positioning plate 3146 and the second positioning plate 3148 are both vertically arranged cuboids; the first positioning plate 3146 and the second positioning plate 3148 are arranged adjacent to each other in the left and right directions, and in the initial state, the push rods of the first positioning plate driving member 3147 and the second positioning plate driving member 3149 are in the retracted state, and the lower end surface of the first positioning plate 3146 is higher than the lower end of the second positioning plate 3148; In this embodiment, the first positioning plate driving module is installed as a whole on the second positioning plate 3148. Of course, the first positioning plate driving module and the second positioning plate driving module can also be arranged separately; When the first positioning plate 3146 and the second positioning plate 3148 are at the bottom at the same time, their lower end surfaces are in the same horizontal plane.

[0091] The fixed pressure plate assembly includes several fixed pressure plates arranged side by side along the axial direction of the rolled cylindrical plate, and several fixed pressure plate driving components that drive each fixed pressure plate to press or release the end to be welded. The several fixed pressure plates move simultaneously. The several fixed pressure plates include several first fixed pressure plates 3150 that cooperate with the moving base module and several second fixed pressure plates 3152 that cooperate with the fixed base 3143. The several fixed pressure plate driving components include several first fixed pressure plate driving components 3151 that drive the several first fixed pressure plates 3150 and several second fixed pressure plate driving components 3153 that drive the several second fixed pressure plates 3152. In this embodiment, the several first fixed pressure plate driving components 3151 and several second fixed pressure plate driving components 3153 simultaneously drive the several first fixed pressure plates 3150 and several second fixed pressure plates 3152 to press down. Compared with two whole plates directly pressing on the two ends to be welded, pressing down in segments at the same time, firstly, the power is more dispersed, and secondly, the force on the two ends to be welded is more uniform, avoiding the problems of hollowness and unevenness.

[0092] Each first fixed pressure plate 3150 and each second fixed pressure plate 3152 includes a head, a middle portion, and a tail portion away from the head that contacts the end to be welded; the middle portion of each first fixed pressure plate 3150 and each second fixed pressure plate 3152 is hinged to another fixed plate fixed to the frame 01; the tail portion of each first fixed pressure plate 3150 and each second fixed pressure plate 3152 is respectively hinged to the first fixed pressure plate drive member 3151 and the second fixed pressure plate drive member 3153; each first fixed pressure plate 3150 and each second fixed pressure plate 3152 is generally in a lever-like downward and upward position, which makes the force applied to the two ends to be welded more stable; the minimum horizontal spacing between the plurality of first fixed pressure plates 3150 and the plurality of second fixed pressure plates 3152 is greater than or equal to the sum of the horizontal widths of the first positioning pressure plate 3146 and the second positioning pressure plate 3148. The design allows several first fixing plates 3150, several second fixing plates 3152, a first positioning plate 3146, and a second positioning plate 3148 to simultaneously press on the two ends to be welded during the positioning stage before welding. The parts of the heads of the first fixing plates 3150 and the second fixing plates 3152 that contact the ends to be welded are embedded with copper blocks 3154. The copper blocks 3154 can ensure that welding slag does not stick to the first fixing plates 3150 and the second fixing plates 3152, and also ensure that the first fixing plates 3150 and the second fixing plates 3152 will not damage the two ends to be welded. When the barrel plate is a coated barrel plate, the copper blocks 3154 can prevent the coating on the coated barrel from being scratched. The opposite end faces of the first fixing plates 3150 and the second fixing plates 3152 are both inclined surfaces, and the two inclined surfaces are in the shape of an upward-opening trumpet.

[0093] The thickness alignment mechanism 314 aligns the two ends to be welded vertically upwards and downwards (i.e., aligns the wall thickness of the barrel after welding). In this embodiment, the clamping mechanism 312, the height alignment mechanism 313, and the thickness alignment mechanism 314 improve the alignment accuracy between the two ends to be welded.

[0094] The welding assembly 32 includes a plurality of laser welding heads 321 disposed above the rolled cylindrical plate, and a laser welding head 321 drive unit for moving the plurality of laser welding heads 321; the number of laser welding heads 321 is two, and the laser welding head 321 drive unit includes two laser welding head cylinders 322 connected to the two laser welding heads 321, and an electric cylinder 323 for driving the two laser welding head cylinders 322 to reciprocate in the same direction along the gap between the two ends to be welded. Figure 11-12 As shown, in one welding stroke, each laser welding head 321 only needs to weld half the length of the weld seam on a rolled cylindrical plate, thereby improving the welding efficiency of the rolled cylindrical plate. In practical applications, the number of laser welding heads 321 can be set as needed, and is not limited here.

[0095] Feeding mechanism 4

[0096] After the rolled cylindrical plate is welded, it forms the barrel body. The feeding mechanism 4 pushes the welded barrel body away from the positioning mechanism 31; as follows: Figure 2 As shown, the unloading mechanism 4 includes a horizontal unloading module 41 that moves horizontally and a lifting drive 413 that drives the horizontal unloading module 41 to lift as a whole. The horizontal unloading module 41 includes an unloading push plate 411 disposed on the side of the rolled cylindrical plate and an unloading push plate cylinder 412 that pushes the unloading push plate 411 to move. The lifting drive 413 is a lifting cylinder, and the push rod of the lifting cylinder is fixedly connected to the cylinder body of the unloading push plate cylinder 412.

[0097] The working principle is explained as follows:

[0098] In this embodiment, during one work cycle, the feeding mechanism 1 and the welding mechanism 3 operate at the same time interval, and the transfer mechanism 2 and the unloading mechanism 4 operate at the same time interval. That is, while the feeding mechanism 1 is feeding and rolling the material, the welding mechanism 3 positions and welds the rolled barrel plate that was transported by the transfer mechanism 2 in the previous work cycle. At the same time, the unloading mechanism 4 moves the welded barrel body out of the welding mechanism 3, and the transfer mechanism 2 transports the rolled barrel plate into the welding mechanism 3. For ease of understanding, the two ends to be welded are respectively referred to as the first end to be welded 03 and the second end to be welded 04.

[0099] Phase 1: Operation of feeding mechanism 1 and welding mechanism 3

[0100] Feeding and rolling

[0101] In the initial state, there is no rolled cylindrical plate on the guide support mechanism 13 in the feeding mechanism 1.

[0102] The flat plate is conveyed to the three-roller rolling mechanism 12 by the plate conveying mechanism 11. Through the combined action of the upper roller 121, lower roller 122 and side roller 123 of the three-roller rolling mechanism 12, the flat plate is deformed and rolled into a cylindrical shape. During the rolling process, the guide plate group 131 guides the copper plate in the rolling process. After the rolling is completed, the rolled plate is in a horizontal position.

[0103] Positioning before welding

[0104] In the initial state, the positioning mechanism 31 contains a rolled cylindrical plate that was conveyed into the positioning mechanism 31 by the transfer mechanism 2 in the previous working cycle.

[0105] 2-a In the initial state, the upper left roller group 2211, upper right roller group 2221, and lower roller group 2231 of the spreading assembly 22 are all separated from the inner wall of the rolled cylindrical plate; the first arc-shaped clamping member 3121 and the second arc-shaped clamping member 3123 of the clamping mechanism 312 are in the open state; the moving seat 3141 is driven to the highest point by the moving seat driving member 3142, at which time the top surface of the moving seat 3141 is higher than the top surface of the fixed seat 3143; the oblique driving member 3155 drives the first positioning pressure plate. 3146. The second positioning plate 3148 is positioned directly above the first end to be welded 03 and the second end to be welded 04. At this time, the lower end surface of the first positioning plate 3146 is higher than the lower end surface of the second positioning plate 3148, and the lower end surface of the second positioning plate 3148 is lower than the top surface of the moving seat 3141. The first fixed plate 3150 and the second fixed plate 3152 are both in the raised state. The baffle 3131 of the height alignment mechanism 313 is in the lowered state.

[0106] like Figure 15 As shown in Figure A, after the rolled cylindrical plate is conveyed to the welding mechanism 3 through the transfer mechanism 2, the baffle drive 3132 in the height alignment mechanism 313 drives the baffle 3131 to rise, so that the first end 03 to be welded and the second end 04 to be welded of the rolled cylindrical plate are aligned in height.

[0107] The base 311 supports and fixes the rolled cylindrical plate. The first clamping member drive 3122 and the second clamping member drive 3124 in the clamping mechanism 312 simultaneously drive the first arc-shaped clamping member 3121 and the second arc-shaped clamping member 3123 to move horizontally towards each other to clamp the rolled cylindrical plate. This causes the first end to be welded 03 to be located in the space between the lower end face of the first positioning pressure plate 3146 and the top surface of the moving seat 3141. Due to the clamping force, the first end to be welded 03 abuts against the side of the second positioning pressure plate 3148. The second end to be welded 04 is located in the space between the lower end face of the second positioning pressure plate 3148 and the top surface of the fixed seat 3143. Due to the clamping force, the second end to be welded 04 abuts against the side of the moving seat 3141. At this time, the end faces of the first end to be welded 03 and the second end to be welded 04 are in the same vertical plane.

[0108] 2-b such as Figure 15 As shown in Figure B, the second positioning plate drive 3149 in the thickness alignment mechanism 314 drives the second positioning plate 3148 to press down; at the same time, the second positioning plate 3148 presses down and also drives the first positioning plate 3146 to press down a small distance.

[0109] 2-c such as Figure 15 As shown in Figure C, the moving seat drive member 3142 in the thickness alignment mechanism 314 drives the moving seat 3141 to descend, at which time the top surface of the moving seat 3141 is flush with the top surface of the fixed seat 3143.

[0110] 2-d such as Figure 15 As shown in Figure D, the first positioning plate drive 3147 in the thickness alignment mechanism 314 drives the first positioning plate 3146 to press down.

[0111] 2-e, for example Figure 15 As shown in Figure E, several first fixed pressure plate driving members 3151 and several second fixed pressure plate driving members 3153 in the thickness alignment mechanism 314 simultaneously drive several first fixed pressure plates 3150 and several second fixed pressure plates 3152 to press down, fixing the first end 03 and the second end 04 to be welded after positioning, waiting for the welding assembly 32 to weld; the first positioning pressure plate driving member 3147 and the second positioning pressure plate driving member 3149 drive the first positioning pressure plate 3146 and the second positioning pressure plate 3148 to reset respectively; the oblique driving member 3155 drives the first positioning pressure plate driving module and the second positioning pressure plate driving module to reset.

[0112] (3) Welding

[0113] In the welding assembly 32, two laser welding head cylinders 322 drive two laser welding heads 321 to move directly above the first end 03 to be welded and the second end 04 to be welded. The electric cylinder 323 drives the two laser welding heads 321 to move simultaneously in the same direction to weld the gap between the first end 03 to be welded and the second end 04 to be welded. After the rolled cylindrical plate is welded, it becomes the barrel body.

[0114] Phase Two: Actions of Conveying Mechanism 3 and Unloading Mechanism 4

[0115] In the initial state, the pusher 214 of the transfer mechanism 2 is located at the end of the guide support mechanism 13 away from the welding positioning assembly; the push rod of the lifting cylinder of the unloading mechanism 4 is in the downward extension state, the push rod of the unloading push plate cylinder 412 is in the retracted state, and the top surface of the unloading push plate 411 is outside the diameter range of the rolled barrel plate.

[0116] The electric cylinder 323 and the two laser welding head cylinders 322 jointly drive the two laser welding heads 321 to reset. Several first fixed pressure plates 3150 are lifted, and the first arc-shaped clamping member 3121 and the second arc-shaped clamping member 3123 are opened and reset. The upper left side opening drive member 2212 and the upper right side opening drive member 2222 of the opening assembly 22 simultaneously drive the upper left side roller group 2211 and the upper right side roller group 2221 to fit against the inner wall of the rolled cylindrical plate and / or the barrel body.

[0117] The push drive of the transfer mechanism 2 drives the belt 213, which in turn moves the pusher 214. The pusher 214 pushes the rolled cylindrical plate to the welding mechanism 3. At the same time, the lifting cylinder drives the push rod to retract, causing the horizontal unloading module 41 to rise as a whole. At this time, the unloading push plate 411 rises, and the top surface of the unloading push plate 411 is within the diameter range of the barrel body. The unloading push plate cylinder 412 drives the unloading push plate 411 to lift the welded barrel body from the welding mechanism 3. The positioning mechanism 31 is pushed away; at the same time, several lower supporting drive members 2232 sequentially drive each lower roller group 2231 (lower left roller 2231a, lower right roller 2231b, lower roller 2231c) to fit against the inner wall of the rolled cylindrical plate. Whenever the barrel body leaves the vertical orthographic projection position of the lower supporting module 223, the lower supporting module 223 will act to open up the inside of the rolled cylindrical plate conveyed by the transfer mechanism 2.

[0118] After the transfer mechanism 2 completely conveys the rolled cylindrical plate into the welding mechanism 3 and the unloading mechanism 4 completely removes the welded barrel body from the welding mechanism 3, the belt 213 of the transfer mechanism 2 drives the pusher 214 to move to the end of the guide support mechanism 13 away from the welding positioning component. The lifting cylinder of the unloading mechanism 4 drives the push rod to extend downward, causing the horizontal unloading module 41 to descend as a whole. At this time, the unloading push plate 411 descends, and the push rod of the unloading push plate cylinder 412 retracts to reset the unloading push plate 411.

[0119] Returning to the first stage, this cycle repeats.

[0120] In this embodiment, each laser welding head 321 has a power of 2000 watts, which can weld 5 or 6 coated barrels per minute, greatly improving the working efficiency of the entire device.
