Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an automatic welding machine for warehouse column plates. Background Technology

[0002] The warehouse uprights are the most basic load-bearing components of the racking system. All the forces on the racking system must be transmitted to the uprights. When subjected to force on the ground or floor, they are composed of main uprights, horizontal uprights, and diagonal uprights welded together.

[0003] Although there are existing devices for automatically welding column pieces, such as the utility model patent with authorization announcement number CN 218426411U, which discloses a warehouse column piece welding machine, although it can automatically weld column pieces, it is a single-station design and cannot achieve continuous welding operations, thus affecting processing efficiency. The invention patent application with announcement number CN 119589190 A discloses a flip-type column piece welding device and column piece welding method. This device has two sets of material positioning frames, which can realize that when one set of material positioning frames is in the welding state, the other set of material positioning frames can simultaneously load and unload materials, which can significantly improve the processing efficiency of column pieces. However, the two sets of material positioning frames are connected by a connecting rod to realize the linkage between the two. As a result, when the material on one set of material positioning frames is being loaded and unloaded, the vibration generated will affect the stability of the other set of material positioning frames that are being welded, which has a significant impact on the stability of the welding.

[0004] In addition to the welding required on both sides of the joint between the main column and the horizontal column and the diagonal column, in order to ensure the stability of the column when placed on the ground, a foot piece is usually welded to each end face of the main column that contacts the ground. In order to ensure the stability of the overall structure, the foot pieces need to be welded in a three-point fixing manner. However, the existing technology cannot solve this technical problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic welding machine for warehouse column plates.

[0006] The technical solution of this utility model is:

[0007] An automatic welding machine for warehouse column plates, characterized in that it comprises:

[0008] The frame is provided with two parallel and spaced first fixed frame slide rails and second fixed frame slide rails along the X direction. Each of the first fixed frame slide rails and the second fixed frame slide rails is slidably connected to a column plate fixed frame, and the two column plate fixed frames are arranged side by side.

[0009] On the frame, parallel to the slide rail of the first fixed frame, there is a welding guide rail. A movable seat is slidably connected to the welding guide rail.

[0013] Furthermore, the welding guide rail includes an upper welding guide rail and a lower welding guide rail; the movable seat includes an upper movable seat slidably connected to the upper welding guide rail and a lower movable seat slidably connected to the lower welding guide rail.

[0014] The upper welding guide rail is located on the top surface of the first substrate. The upper movable seat is connected to the front and rear ends of the column plate fixing frame and a welding gun moving mechanism with multiple degrees of freedom. The driving end of each welding gun moving mechanism is connected to the welding gun. The lower welding guide rail is located on the third substrate and corresponds to the position of the upper welding guide rail. The lower movable seat is connected to the front and rear ends of the column plate fixing frame and a welding gun moving mechanism. The driving end of each welding gun moving mechanism is connected to the welding gun.

[0015] Furthermore, the upper moving seat is provided with an upper moving seat drive mechanism that cooperates with the upper welding guide rail, and the lower moving seat is provided with a lower moving seat drive mechanism that cooperates with the lower welding guide rail. Both the upper moving seat drive mechanism and the lower moving seat drive mechanism are electrically connected to the controller so as to realize that the upper moving seat automatically moves back and forth along the upper welding guide rail, and the lower moving seat automatically moves back and forth along the lower welding guide rail.

[0016] Furthermore, each of the column plate fixing frames includes two parallel fixing frame horizontal plates extending along the X direction from top to bottom. Each end of the two fixing frame horizontal plates along the X direction is connected to a fixing frame side plate. Each fixing frame side plate is set perpendicular to the two fixing frame horizontal plates.

[0017] The fixing frame horizontal plate of one column piece fixing frame is slidably connected to the first fixing frame slide rail, and the fixing frame horizontal plate of the other column piece fixing frame is slidably connected to the second fixing frame slide rail;

[0018] Each fixed frame side plate is provided with a width adjustment guide rail along the Z direction. Each width adjustment guide rail is slidably connected to a lifting plate at its upper and lower ends. Each pair of lifting plates opposite each other along the X direction is connected to a floating horizontal plate, and the two floating horizontal plates are located between the two fixed frame horizontal plates.

[0019] Furthermore, each pair of lifting plates opposite each other along the X direction is also connected to a positioning back rod, and the two positioning back rods are located between the two floating horizontal plates; the two floating horizontal plates, the two fixed frame side plates and the two positioning back rods surround to form a loading frame for placing the column plate.

[0020] Furthermore, each of the floating horizontal plates is provided with a first clamping assembly, the drive end of which is connected to a first pressure plate, which clamps the column plate between the first pressure plate and the column plate fixing frame along the Y direction.

[0021] Each of the positioning back rods is provided with a second clamping assembly, the drive end of which is connected to a second pressure plate, which clamps the column plate between the second pressure plate and the column plate fixing frame along the Z direction.

[0022] Furthermore, each of the positioning back bars is also provided with several positioning components for positioning the horizontal or oblique columns on the positioning column plate.

[0023] Each positioning component includes a reference block and a magnetic block. The reference block includes two mutually perpendicular mounting parts and a magnetic suction part. Each mounting part is detachably mounted on each positioning back rod, and its position corresponds to the predetermined horizontal or diagonal column position. Each magnetic suction part abuts against the side of the horizontal or diagonal column, and the magnetic block is placed at the abutment point between each magnetic suction part and the horizontal or diagonal column.

[0024] Furthermore, on the side of each column plate fixing frame along the Y direction, there are positioning magnetic plates installed on the two lifting plates facing the column plate to position the foot plate located at one end of the column plate.

[0025] The rear side of the frame is also provided with a foot piece welding mechanism for welding foot pieces, and when a column piece fixing frame slides to one end of the frame, the foot piece welding mechanism corresponds to the position of the positioning magnetic piece.

[0026] The foot welding mechanism includes a multi-degree-of-freedom driven foot welding drive unit mounted on a frame and a foot welding gun connected to the drive end of the foot welding drive unit.

[0027] The beneficial technical effects of this utility model are:

[0028] Firstly, compared with the existing technology, the two column plate fixing frames of this utility model adopt a parallel and independent sliding arrangement. When one column plate fixing frame slides to the welding processing area for welding processing, the other column plate fixing frame can be loaded and unloaded at the same time. The process has a high degree of automation and high processing efficiency. Moreover, the parallel and independent sliding design of the two column plate fixing frames avoids the problem of vibration generated when one column plate fixing frame is loaded and unloaded affecting the stability of the other column plate fixing frame, resulting in high welding accuracy.

[0029] Secondly, this utility model also includes a positioning magnetic sheet and a multi-degree-of-freedom driven foot welding mechanism for positioning and welding the foot pieces, which has a high degree of automation.

[0030] Thirdly, each column piece fixing frame of this utility model is also equipped with a clamping component and a positioning component to prevent the horizontal and diagonal columns from shifting during the welding process, thereby further ensuring the welding accuracy of the column pieces.

Detailed Implementation

[0039] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] This utility model provides an automatic welding machine for warehouse column plates, which is used for welding warehouse column plates. Figure 6 As shown, the column plate 100 includes two parallel main columns 101 extending along the X-direction, a transverse column 102 located between the two main columns 101 and perpendicularly connected to them, and an oblique column 103 located between the two main columns 101 and obliquely connected to them. The welding machine of this invention is used to weld and fix the front and back sides (front and back) of the joints between the transverse column 102 and the main column 101, and between the oblique column 103 and the main column 101. For ease of description, the joints between the transverse column 102 and the main column 101, and between the oblique column 103 and the main column 101, are defined as welding points. The number of transverse columns 102 and oblique columns 103 can be set according to actual usage requirements and is not particularly limited.

[0041] In this utility model, the following example is used: three horizontal columns 102 are provided between two main columns 101, and an oblique column 103 is provided between the two main columns 101 and between every two horizontal columns 102, with the two oblique columns 103 having opposite inclination directions.

[0042] like Figures 1-5 As shown, this utility model includes a frame 200 that provides a foundation for mounting other components. The frame 200 is a frame structure that includes, from top to bottom, a first substrate 201, a second substrate 202, and a third substrate 203. The first substrate 201, the second substrate 202, and the third substrate 203 are all long rectangles that extend along the X-direction and are parallel and spaced apart from each other along the X-direction. Each end of the first substrate 201, the second substrate 202, and the third substrate 203 along the X-direction is connected to a frame side plate 204. Each frame side plate 204 is arranged perpendicular to the first substrate 201, the second substrate 202, and the third substrate 203.

[0043] On the bottom surface of the first substrate 201 facing the second substrate 202, two parallel and spaced-apart first fixing bracket slide rails 2012 and second fixing bracket slide rails 2013 are respectively provided along the X direction, and both the first fixing bracket slide rails 2012 and second fixing bracket slide rails 2013 pass through both ends of the first substrate 201 along the X direction; on the top surface of the second substrate 202 facing the first substrate 201, two parallel and spaced-apart first fixing bracket slide rails 2012 and second fixing bracket slide rails 2013 are also provided along the X direction, and the positions of the first fixing bracket slide rails 2012 on the second substrate 202 correspond vertically to the positions of the first fixing bracket slide rails 2012 on the first substrate 201, and their lengths are equivalent; the positions of the second fixing bracket slide rails 2013 on the second substrate 202 correspond vertically to the positions of the second fixing bracket slide rails 2013 on the first substrate 201, and their lengths are equivalent.

[0044] A column piece fixing bracket 500 is slidably connected to the first fixing bracket slide rail 2012 on the first substrate 201 and the second substrate 202 along the X direction. A column piece fixing bracket 500 is also slidably connected to the second fixing bracket slide rail 2013 on the first substrate 201 and the second substrate 202 along the X direction. The two column piece fixing brackets 500 can slide independently along the first fixing bracket slide rail 2012 or the second fixing bracket slide rail 2013 in the same direction or opposite direction, simultaneously or not simultaneously. That is, the column piece fixing brackets 500 on the first fixing bracket slide rail 2012 and the second fixing bracket slide rail 2013 do not affect each other when they slide. When the column piece fixing bracket 500 on the first fixing bracket slide rail 2012 slides to one end of the first substrate 201 and the column piece fixing bracket 500 on the second fixing bracket slide rail 2013 slides to the other end of the first substrate 201, the two column piece fixing brackets 500 have no overlapping part, so as to ensure that the column pieces on the column piece fixing brackets 500 can be independently loaded, welded and unloaded.

[0045] To accommodate the loading, welding, and unloading processes of multiple column pieces and improve production efficiency, this embodiment includes two column piece fixing frames 500.

[0046] Each column piece fixing bracket 500 is also a frame structure, including two parallel fixing bracket horizontal plates 501 extending along the X direction from top to bottom. In order to ensure that the column piece fixing bracket 500 on the first fixing bracket slide rail 2012 slides to one end of the first base plate 201 and the column piece fixing bracket 500 on the second fixing bracket slide rail 2013 slides to the other end of the first base plate 201, the two column piece fixing brackets 500 do not overlap or obstruct each other. The length of each fixing bracket horizontal plate 501 is set to be ≤1 / 2 the length of the first base plate 201. However, in order to maximize compatibility with column pieces of different lengths, in this embodiment, the length of each fixing bracket horizontal plate 501 is equivalent to half the length of the first base plate 201.

[0047] Two fixed frame horizontal plates 501 are connected to a fixed frame side plate 502 at both ends along the X direction, and each fixed frame side plate 502 is set perpendicular to the two fixed frame horizontal plates 501.

[0048] As described above, the upper and lower fixing bracket horizontal plates 501 of one column plate fixing bracket 500 are respectively slidably connected to the upper and lower first fixing bracket slide rails 2012, and the upper and lower fixing bracket horizontal plates 501 of the other column plate fixing bracket 500 are respectively slidably connected to the upper and lower second fixing bracket slide rails 2013.

[0049] It should be noted that the column piece fixing bracket 500 can be manually slidable by applying force, or a first fixing bracket drive mechanism 205 cooperating with the first fixing bracket slide rail 2012 can be set on a fixing bracket horizontal plate 501 in one column piece fixing bracket 500, and a second fixing bracket drive mechanism 206 cooperating with the second fixing bracket slide rail 2013 can be set on a fixing bracket horizontal plate 501 in another column piece fixing bracket 500. Both the first fixing bracket drive mechanism 205 and the second fixing bracket drive mechanism 206 are electrically connected to a controller (not shown), thereby realizing that one column piece fixing bracket 500 automatically moves back and forth along the first fixing bracket slide rail 2012, and the other column piece fixing bracket 500 automatically moves back and forth along the second fixing bracket slide rail 2013.

[0050] In one embodiment, the first fixed frame drive mechanism 205 and the second fixed frame drive mechanism 206 may be pulleys connected to the motor drive end, and the pulleys are in contact with the first fixed frame slide rail 2012 and the second fixed frame slide rail 2013, such as a servo motor;

[0051] In another embodiment, the first fixed frame drive mechanism 205 and the second fixed frame drive mechanism 206 can be lead screw modules. Taking the first fixed frame drive mechanism 205 as a lead screw module as an example: the lead screw in the lead screw module is arranged parallel to the first fixed frame slide rail 2012. The rotary motor that drives the lead screw to rotate is mounted on the first base plate or the second base plate. One end of one of the fixed frame horizontal plates 501 on the column plate fixed frame 500 is slidably connected to the first fixed frame slide rail 2012 by a slider, and the other end of the fixed frame horizontal plate 501 is connected to the lead screw nut on the lead screw.

[0052] Furthermore, to accommodate column plates 100 of different widths, each fixed frame side plate 502 has an adjustable width guide rail 503 along the Z direction on its inner side wall; each adjustable width guide rail 503 is slidably connected to a lifting plate 504 at its upper end and also slidably connected to a lifting plate 504 at its lower end; each pair of lifting plates 504 facing each other along the X direction is connected to a floating horizontal plate 505, one end of each floating horizontal plate 505 is fixedly connected to or detachably connected to a lifting plate 504 by bolts, and the other end of each floating horizontal plate 505 is fixedly connected to or detachably connected to another opposite lifting plate 504 by bolts. Each floating horizontal plate 505 is parallel to the fixed frame horizontal plate 501, and the two floating horizontal plates 505 are located between the two fixed frame horizontal plates 501.

[0053] The upright plate 100 is placed within the loading frame formed by two floating horizontal plates 505 and two fixed side plates 502, with the main upright 101 of the upright plate 100 placed parallel to the floating horizontal plates 505. When the lifting plate 504 slides up and down along the width adjustment guide rail 503, the width between the two floating horizontal plates 505 can be adjusted to accommodate the width of the upright plate 100, so that the outer walls of the two main uprights 101 respectively abut against the inner walls of their corresponding floating horizontal plates 505, ensuring their stability during the welding process.

[0054] It should be noted that the sliding of the lifting plate 504 can be achieved by manually applying force to make it slide up and down along the Z direction, or by adding a linear module with a driving direction along the Z direction. Each lifting plate 504 is connected to the driving end of the linear module, and is driven by the linear module to move up and down along the Z direction to adjust the spacing of the floating horizontal plates 505. The linear module is existing technology and will not be described in detail here.

[0055] Furthermore, a positioning back rod 506 is also connected to a pair of lifting plates 504 located above the width adjustment guide rail 503 and opposite each other in the X direction. A positioning back rod 506 is also connected to another pair of lifting plates 504 located below the width adjustment guide rail 503 and opposite each other in the X direction. The two positioning back rods 506 are located between the two floating horizontal plates 505, and each positioning back rod 506 is connected to the rear side of each lifting plate 504 away from the direction in which the column piece 100 is placed into the loading frame. That is, each positioning back rod 506 forms the back plate of the loading frame to prevent the column piece 100 from falling when it is placed into the loading frame.

[0056] To prevent the column piece 100 from shifting during the welding process and affecting its welding accuracy, each column piece fixing frame 500 is provided with several clamping components. Each clamping component includes several first clamping components installed on each floating horizontal plate 505 and several second clamping components installed on each positioning back rod 506.

[0057] Each first clamping assembly includes a first linear drive cylinder 601 with a drive direction along the Z direction. The drive end of the first linear drive cylinder 601 is connected to a connecting plate. Each connecting plate is connected to a first clamping cylinder 602 with a drive direction along the Y direction. The drive end of each first clamping cylinder 602 is connected to a first pressure plate 603.

[0058] The fixed end of each first linear drive cylinder 601 is installed on the front side of each floating cross plate 505 away from the positioning back rod 506. When the column plate 100 is placed in the loading frame, each first linear drive cylinder 601 drives the first clamping cylinder 602 and the first pressure plate 603 to move along the Z direction to each main column 101. Then, each first clamping cylinder 602 drives the first pressure plate 603 to move towards the positioning back rod 506, thereby clamping each main column 101 between the first pressure plate 603 and the positioning back rod 506.

[0059] The number of the first clamping components or their positions on the floating horizontal plate 505 can be set according to actual needs and are not particularly limited. For example, the number and position can be set according to the length of the column piece 100 to accommodate the fixing of column pieces 100 of different lengths. In this embodiment, three first clamping components are provided at intervals on each floating horizontal plate 505.

[0060] Each second clamping assembly includes a second clamping cylinder 701 with the driving direction along the Z direction, and a second pressure plate 702 is connected to the driving end of each second clamping cylinder 701.

[0061] The fixed end of each second clamping cylinder 701 is installed on the front side of the positioning back rod 506. When the column plate 100 is placed in the loading frame, each second clamping cylinder 701 drives the second pressure plate 702 to move towards its corresponding floating horizontal plate 505, thereby clamping the upper main column 101 between the second pressure plate 702 and the upper floating horizontal plate 505, and clamping the lower main column 101 between the second pressure plate 702 and the lower floating horizontal plate 505.

[0062] Before welding, each horizontal column 102 and each diagonal column 103 of the column piece 100 are connected to the main column 101 by snap-fit. In order to prevent the horizontal columns 102 and diagonal columns 103 on the column piece 100 from shifting during loading or welding, which would affect the subsequent welding accuracy and the stability of the final column piece structure, several positioning components are installed on the front side of each positioning back rod 506 facing the column piece.

[0063] Each positioning component includes a reference block 801 and a magnetic block (not shown). The reference block 801 includes two mutually perpendicular mounting portions 8011 and magnetic suction portions 8012, both of which are rectangular. Each mounting part 8011 is detachably mounted on each positioning back rod 506 by bolts, and its position corresponds to the predetermined position of the horizontal column 102 and the inclined column 103. Each magnetic part 8012 faces the column plate and abuts against the side of the horizontal column 102 or the inclined column 103. Then, a magnetic block is placed at the abutment of each magnetic part 8012 with the horizontal column 102 or the inclined column 103. Since the column plate and the reference block are made of ferromagnetic materials, they are magnetic. Thus, the magnetic block can connect each horizontal column 102 and the inclined column 103 with the reference block 801 by magnetic force, thereby avoiding the problem of displacement of the horizontal column 102 and the inclined column 103 during the loading and moving process or during the welding process.

[0064] Specifically, the mounting portion 8011 of the reference block 801 for positioning the horizontal column 102 is installed parallel to the front side of the positioning back rod 506, so that its magnetic attraction portion 8012 is parallel and abuts against the side of the horizontal column 102; the mounting portion 8011 of the reference block 801 for positioning the oblique column 103 is installed obliquely to the front side of the positioning back rod 506, so that its magnetic attraction portion 8012 is also parallel and abuts against the side of the oblique column 103. Then, a magnetic block is placed at the point where each magnetic attraction portion 8012 abuts against the horizontal column 102 or the oblique column 103, thereby connecting each horizontal column 102 and oblique column 103 to the reference block 801 by magnetic force and preventing their displacement.

[0065] Furthermore, an upper welding guide rail 2011 is provided on the top surface of the first substrate 201 along the X direction, and the upper welding guide rail 2011 is located at one end of the top surface of the first substrate 201, and its length is equivalent to the length of the aforementioned fixing frame horizontal plate 501. In this embodiment, the upper welding guide rail 2011 starts at one end of the top surface of the first substrate 201, and its tail ends at the middle section of the top surface of the first substrate 201. An upper moving seat 901 is slidably connected to the upper welding guide rail 2011. The upper moving seat 901 is arranged perpendicular to the first substrate 201. An upper fixing plate 9011 is connected downward at each end of the upper moving seat 901 along the Y direction. Each upper fixing plate 9011 is located on the outside of the first substrate 201. A welding gun moving mechanism is connected to each upper fixing plate 9011. Each welding gun moving mechanism includes a welding gun Z-direction driving module 902 with the driving direction along the Z direction and a welding gun Z-direction driving module 902 with the driving direction along the Y direction. The fixed ends of the welding torch Y-axis drive module 903 and welding torch Z-axis drive module 902 are mounted on the upper fixed plate 9011. The welding torch Y-axis drive module 903 is connected to the drive end of the welding torch Z-axis drive module 902. The welding torch 904 used for welding is connected to the drive end of the welding torch Y-axis drive module 903. That is, two welding torches 904 are provided opposite to each other on each upper moving seat 901, which are used to simultaneously weld the front and back sides (front and back) of each welding point on the upper end of the column plate 100.

[0066] On the front and rear sides of the third substrate 203, a lower welding guide rail 2031 is provided along the X direction, and the position and length of each lower welding guide rail 2031 correspond to the upper welding guide rail 2011.

[0067] Two lower welding guide rails 2031 are slidably connected to the lower moving seat 905. The lower moving seat 905 is set perpendicular to the third base plate 203. The two ends of the lower moving seat 905 along the Y direction are each connected to a lower fixing plate 9051 facing upwards. Each lower fixing plate 9051 is connected to the welding gun moving mechanism and welding gun 904 as described above, which will not be repeated here. That is, each lower moving seat 905 is provided with two welding guns 904 facing each other, which are used to simultaneously weld the front and back sides (front and back) of each welding point at the lower end of the column piece 100.

[0068] The upper moving seat 901 is equipped with an upper moving seat drive mechanism 9012 that cooperates with the upper welding guide rail 2011, and the lower moving seat 905 is equipped with a lower moving seat drive mechanism 9013 that cooperates with the lower welding guide rail 2031. Both the upper moving seat drive mechanism 9012 and the lower moving seat drive mechanism 9013 are electrically connected to the controller to realize that the upper moving seat 901 automatically moves back and forth along the upper welding guide rail 2011, and the lower moving seat 905 automatically moves back and forth along the lower welding guide rail 2031. The controller can also precisely control the stroke of each welding gun 904 to ensure that the welding gun 904 can accurately travel to the joint between the horizontal column 102 and the main column 101, and the diagonal column 103 and the main column 101 for welding and fixing.

[0069] The upper moving seat drive mechanism 9012 and the lower moving seat drive mechanism 9013 are the same as the first fixed frame drive mechanism 205 and the second fixed frame drive mechanism 206 described above, and will not be repeated here.

[0070] The area in which the upper movable seat 901 drives the welding torch 904 to move along the upper welding guide rail 2011, and the area in which the lower movable seat 905 drives the welding torch 904 to move along the lower welding guide rail 2031, is the welding processing area.

[0071] Preferably, the third substrate 203 has several limiting posts 206 connected to the top surface of the second substrate 202 and the other end of the non-welding guide rail 2031. One limiting post 206 is located at the tail end of the lower welding guide rail 2031. On the one hand, the limiting post 206 near the tail end of the lower welding guide rail 2031 has a limiting function. On the other hand, the several limiting posts 206 between the third substrate 203 and the second substrate 202 not only have a reinforcing function, but also mark the area above this region as a non-welding processing area, which corresponds to the loading and unloading area of ​​the column piece or the finished product unloading area after welding.

[0072] In addition, such as Figure 6 As shown, in order to ensure the stability of the column piece 100 when placed on the ground, a foot piece 104 is usually welded to one end face of the upper and lower main columns 101 on the same side. The foot piece 104 is usually a flat plate. In order to pre-fix its connection with the main column 101 and facilitate its subsequent welding, this utility model also installs a positioning magnetic piece 207 on the upper lifting plate 504 and the lower lifting plate 504 on one side along the Y direction in the column piece fixing frame 500. When the column piece 100 to be welded is put into the loading frame, an appropriate gap is left between one end of the main column 101 where the foot piece 104 is installed and the positioning magnetic piece 207 on the corresponding lifting plate 504. Then the foot piece 104 is put into the gap, and the foot piece 104 is pre-fixed to the end face of the main column 101 by magnetic attraction.

[0073] Unlike the above-mentioned horizontal column 102 and main column 101, and diagonal column 103 and main column 101, which are welded and fixed on both sides, each foot piece 104 needs to be welded to the main column 101 at three points to ensure that the column piece has good stability when placed vertically on the ground with the foot piece facing downward.

[0074] Therefore, the present invention also provides a foot piece welding mechanism in the middle part of the frame 200, and when a column piece fixing frame 500 is located in the welding processing area, the end of the column piece that needs to be welded to the foot piece 104 corresponds exactly to the position of the foot piece welding mechanism.

[0075] Specifically, to connect the lead plate welding mechanism, a mounting plate 208 is connected between the first substrate 201 and the second substrate 202. To facilitate the loading and unloading of the column pieces, the mounting plate 208 is mounted on the rear side of the frame. The lead plate welding mechanism includes a lead plate welding drive and a lead plate welding gun 401. The lead plate welding drive includes a lead plate welding Z-axis module 402 with a driving direction along the Z-axis. The fixed end of the lead plate welding Z-axis module is mounted on the mounting plate 208, and its driving end is connected to a lead plate welding Y-axis module 403 with a driving direction along the Y-axis. A connecting plate is connected to the driving end of the lead plate welding Y-axis module 403, and a lead plate welding rotating module 404 is connected to the connecting plate. The lead plate welding gun 401 is connected to the drive shaft of the lead plate welding rotating module 404. The lead plate welding rotating module 404 drives the lead plate welding gun 401 to rotate around its axis to adjust the welding angle of the lead plate welding gun 401. Preferably, the foot piece welding rotating module 404 has a main drive wheel connected to its drive shaft, and a driven wheel connected to one end of the foot piece welding gun 401. The main drive wheel and the driven wheel mesh with each other so that the foot piece welding rotating module 404 drives the foot piece welding gun 401 to rotate around its axis to adjust the welding angle of the foot piece welding gun 401.

[0076] The operation process of this utility model is as follows:

[0077] Feeding:

[0078] A column piece is placed on each of the two column piece fixing brackets 500. The first clamping component, the second clamping component, and the positioning component are activated to fix the column piece. Then, a foot piece 104 is pre-positioned on one side of the upper and lower main column 101 in each column piece by a positioning magnetic piece 207.

[0079] Positioning of column bracket:

[0080] One column plate fixing bracket 500 is slidably positioned in the welding processing area, while the other column plate fixing bracket 500 is slidably positioned in the non-welding processing area;

[0081] welding:

[0082] Under the driving action of the upper moving seat drive mechanism 9012, the two welding guns 904 on the upper moving seat 901 move simultaneously along the X direction, completing the welding of all welding points on the front and back (front and rear) sides of the column plate within one stroke; under the driving action of the lower moving seat drive mechanism 9013, the two welding guns 904 on the lower moving seat 905 also move simultaneously along the X direction, completing the welding of all welding points on the front and back (front and rear) sides of the column plate within one stroke.

[0083] At the same time, the Z-axis welding module 402 and the Y-axis welding module 403 drive the welding gun 401 to the foot piece to be welded. Then, the rotating module 404 drives the welding gun 401 to rotate around its axis to adjust the welding angle of the welding gun 401, so as to achieve three-point welding of the foot piece.

[0084] Material preparation:

[0085] After the welding work is completed on the column piece on one column piece fixing bracket 500, it is slid to the non-welding processing area for unloading and loading of new column pieces. At the same time, the other column piece fixing bracket 500 is slid to the welding processing area for welding of column pieces, and this cycle is repeated.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
