Description

Technical Field

[0001] The present invention relates to the technical field of bracket welding, and particularly to a VR bracket welding device for a VR classroom. Background Art

[0002] With the popularization of virtual reality (VR) technology in the education field, VR classrooms have become an important tool for innovative teaching models. As the core component for fixing and adjusting devices, the structural stability and lightweight design of VR glasses brackets directly affect the user experience. However, the current production of VR brackets still faces the following technical bottlenecks: Most existing brackets are processed by manual welding or general welding equipment, resulting in low welding precision and poor weld consistency. Most of the existing equipment in the industry relies on manual positioning, and welding parameters need to be adjusted manually, which easily leads to a low qualified rate of finished products due to operation errors, driving up the procurement cost of teaching equipment. In view of the above problems, there is an urgent need to develop an automated welding device dedicated to VR brackets, which can improve welding efficiency and product quality through automatic docking positioning, self-welding, and automatic feeding designs, and meet the needs of the education industry for the rapid iteration of VR hardware. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: A VR bracket welding device for a VR classroom, including a main body mechanism for driving the bracket chassis and the bracket rod to move. The main body mechanism includes a bottom plate, and a welding mechanism for automatically welding the bracket chassis and the bracket rod and a feeding mechanism for automatically feeding the bracket rod are arranged on the main body mechanism; The main body mechanism includes a left frame and a right frame fixedly installed on the bottom plate. A main sliding frame is fixedly installed on the left frame, and a clamping module is arranged on the main sliding frame.

[0004] Further, the main body mechanism further includes a driving wheel rotatably installed on the main sliding frame. Three driven wheels are rotatably installed on the main sliding frame. A pull rope is wound around the left frame and the three driven wheels. A placing rail and a discharging rail are fixedly installed on the main sliding frame. A moving motor is fixedly installed on the main sliding frame. A motor gear is fixedly installed on the motor shaft of the moving motor. A driving gear is fixedly installed on the driving wheel, and the driving gear meshes with the motor gear.

[0005] Further, a placing cylinder is fixedly installed on the main sliding frame. A plurality of bracket chassis are stacked in the placing cylinder. A pushing rod is slidably installed on the main sliding frame. A bottom plate is fixedly installed on the pushing rod. A pushing spring is arranged between the pushing rod and the main sliding frame. In the initial state, the bottom plate is located below the placing cylinder.

[0006] Further, the clamping module includes a movable plate slidably mounted on the main carriage. The movable plate is fixedly installed with a pulling rope. A rotating shaft is rotatably mounted on the movable plate. A rotating rod and a rotating gear are fixedly installed on the rotating shaft. Two clamping rods are slidably mounted on the rotating rod. Clamping pieces are fixedly installed on the clamping rods. A clamping spring is arranged between the clamping pieces and the rotating rod. A spreading block is fixedly installed below the clamping piece.

[0007] The moving motor rotates to drive the motor gear to rotate, driving the driving gear and the driving wheel to rotate, thereby driving the pulling rope to move. The pulling rope drives the movable plate to slide along the main carriage. When the pulling rope drives the movable plate to slide towards the placing cylinder, when the rotating rod contacts the pushing rod, it will push the pushing rod and the bottom plate box to move outwards. The pushing spring is compressed. The spreading block contacts the placing rail. Under the action of the placing rail, the spreading block, the clamping piece and the clamping rod are pushed to slide outwards. The clamping spring is stretched. When the clamping piece moves below the placing cylinder, at this time the rotating rod pushes the bottom plate away from below the placing cylinder. The lowest support chassis in the placing cylinder falls onto the two clamping pieces. Subsequently, the pulling rope drives the movable plate to move away from the placing cylinder. The pushing spring gradually rebounds, causing the bottom plate to return below the placing cylinder. The bottom plate prevents the support chassis in the placing cylinder from falling out. When the spreading block disengages from the placing rail, the clamping spring rebounds, causing the two clamping pieces to slide inwards, clamping the support chassis through the clamping pieces. Subsequently, the movable plate drives the support chassis to reach beside the automatic welding torch.

[0008] Further, the welding mechanism includes an electric cylinder fixedly installed on the left frame. An extending frame is fixedly installed at the output end of the electric cylinder. A fixed frame is fixedly installed on the left frame. The electric cylinder is fixedly installed with the right frame. The fixed frame is fixedly installed with the right frame. A rack is fixedly installed on the extending frame. A welding frame is slidably mounted on the fixed frame. An automatic welding torch is fixedly installed on the welding frame. A welding spring is arranged between the welding frame and the extending frame.

[0009] When the bracket chassis reaches the automatic welding gun, the electric cylinder extends to drive the extension frame to move, and the extension frame pushes the welding frame to slide relative to the fixed frame through the welding spring, so that the automatic welding gun contacts the to-be-welded parts of the bracket chassis and the bracket rod. First, the bracket chassis and the bracket rod are spot-welded by the automatic welding gun. As the extension frame continues to move, the rack begins to mesh with the rotating gear, and the rack drives the rotating gear and the rotating rod to rotate, thereby driving the bracket chassis to rotate. Since the automatic welding gun has spot-welded the bracket chassis and the bracket rod, the bracket chassis and the bracket rod rotate together at this time, and finally the rack drives the rotating gear, the rotating rod, the bracket chassis and the bracket rod to rotate three hundred Sixty degrees, the bracket chassis and the bracket rod are automatically welded in a full circle by the automatic welding gun. When the automatic welding gun contacts the parts of the bracket chassis and the bracket rod to be welded, the extension frame continues to move, which will compress the welding spring. The automatic welding gun keeps in contact with the parts of the bracket chassis and the bracket rod to be welded. After the welding of the bracket chassis and the bracket rod is completed, the pull rope moves the movable plate to the discharge rail, and the support block contacts the discharge rail. Under the action of the discharge rail, the support block, the clamping plate and the clamping rod are pushed to slide outward, and the clamping spring is stretched. At this time, the clamping plate no longer clamps the bracket chassis, and the welded bracket chassis and bracket rod are manually removed.

[0010] Furthermore, the feeding mechanism includes an upper connecting frame fixedly mounted on the left frame and the right frame, an upper frame fixedly mounted on the upper connecting frame, a plurality of support rods placed on the upper frame, a feed block slidably mounted on the upper frame, a feed spring is arranged between the feed block and the upper frame, a lower fixed column is fixedly mounted on the upper frame, a lower pressure rod is slidably mounted on the lower fixed column, a lower spring is arranged between the lower pressure rod and the lower fixed column, a blocking triangle block is fixedly mounted on the lower pressure rod, a slope is arranged on the upper surface of the blocking triangle block, a plurality of support rods are located between the feed block and the blocking triangle block, and two limit frames for limiting the support rods are fixedly mounted on the upper frame.

[0011] Furthermore, a top electric cylinder is fixedly installed on the upper frame, a lifting plate is fixedly installed on the output end of the top electric cylinder, a column is fixedly installed on the upper frame, the lifting plate and the column are slidably installed, an inner lifting column is fixedly installed below the lifting plate, an outer lifting cylinder is slidably installed on the inner lifting column, an inner spring is arranged between the inner lifting column and the outer lifting cylinder, a descending frame is fixedly installed on the lifting plate, an upper column is fixedly installed below the lifting plate, a lower frame is slidably installed on the upper column, a compression spring is arranged between the lower frame and the upper column, two ejection cone blocks are fixedly installed below the lower frame, two slopes are arranged on the lower surface of the ejection cone blocks, and a slope is arranged above the bracket rod.

[0012] Furthermore, a motor is fixedly mounted on the upper frame, and two conveying wheels are rotatably mounted on the upper frame. The motor drives the conveying wheels to rotate through gear transmission. Conveyor belts are wrapped around the two conveying wheels, and a push plate is fixedly mounted on the conveyor belts.

[0013] Further, an upper fixing frame is fixedly installed on the upper shelf. A descending rod is slidably installed on the upper fixing frame. A descending spring is arranged between the descending rod and the upper fixing frame. A sliding column is slidably installed on the descending rod. A descending plate is fixedly installed on the sliding column. A sliding column spring is arranged between the descending plate and the descending rod.

[0014] When the support chassis reaches beside the automatic welding torch, the top electric cylinder contracts to drive the lifting plate, the inner lifting column, the outer lifting cylinder, the descending frame, the upper column, the lower shelf and the ejecting cone block to descend. The support rod located on the descending plate is pressed down through the outer lifting cylinder. The outer lifting cylinder presses down the support rod, the descending plate and the descending rod together. The descending spring is stretched until the support chassis is docked with the support rod. When the ejecting cone block descends to contact the two support rods below it, at this time, the two slopes of the ejecting cone block are in contact with the slopes of the two support rods below the ejecting cone block. At this time, the descending frame starts to contact the pressing rod. The lifting plate continues to descend. Since the blocking triangular block blocks the support rod at this time, the ejecting cone block cannot push out the support rod on its right side at this time. The compression spring is compressed. The descending frame pushes the pressing rod and the blocking triangular block to descend along the lower fixed column. The lower spring is compressed. When the blocking triangular block descends a certain distance, it no longer blocks the support rod. At this time, the compression spring rebounds and pushes the ejecting cone block downward, thereby pushing the support rod on the right side of the ejecting cone block under the conveyor belt. At the same time, the support rod on the left side of the ejecting cone block is pushed to the left, and the feeding spring is further compressed. When the support rod and the support chassis are welded, the support chassis drives the support rod to rotate 90 degrees, and then the support rod leaves above the descending plate. At this time, the top electric cylinder extends, and the descending rod and the descending plate return to the initial position under the rebound of the descending spring. The ejecting cone block and the descending frame rise, and the lower spring rebounds, causing the blocking triangular block to rise again. The feeding spring rebounds, and the subsequent support rod is pushed forward through the feeding block, so that the rightmost support rod contacts the blocking triangular block. The motor drives the conveyor wheel to rotate through gear transmission, thereby driving the conveyor belt to rotate. The support rod is toggled above the descending plate through the push plate to prepare for the next feeding, and so on.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The main body mechanism provided in the present invention can drive the clamping module to move. When the clamping module reaches the placement cylinder, the clamping piece opens to automatically load the bracket chassis. When the clamping module reaches beside the welding mechanism, the bracket chassis is clamped by the clamping piece. When the clamping mechanism brings the welded VR bracket to the discharge rail, the clamping piece opens for easy removal, realizing full-automatic feeding, welding, and discharging operations; (2) The welding mechanism provided in the present invention first performs electric welding on the bracket chassis and the bracket rod, and then drives the bracket chassis and the bracket rod to rotate 360 degrees, realizing full-automatic circumferential welding of the bracket chassis and the bracket rod, with high automation and good continuity; (3) The feeding mechanism provided in the present invention can automatically place the bracket rod to be welded on the bracket chassis to be welded, and the entire feeding operation is fully automatic. It only requires manual placement of multiple bracket rods on the upper rack, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0031] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0032] Example: Refer to Figures 1 - 14 , a VR bracket welding device for a VR classroom, including a main body mechanism for driving the bracket chassis 4 and the bracket rod 5 to move. The main body mechanism includes a bottom plate 101, and a welding mechanism for automatically welding the bracket chassis 4 and the bracket rod 5 and a feeding mechanism for automatically feeding the bracket rod 5 are provided on the main body mechanism; The main body mechanism includes a left frame 102 and a right frame 103 fixedly installed on the bottom plate 101. A main sliding frame 104 is fixedly installed on the left frame 102, and a clamping module is arranged on the main sliding frame 104.

[0033] As Figures 4 - 6 shown, the main body mechanism further includes a driving wheel 112 rotatably installed on the main sliding frame 104. Three driven wheels 106 are rotatably installed on the main sliding frame 104. A pulling rope 107 is wound around the left frame 102 and the three driven wheels 106. A placing rail 105 and a discharging rail 108 are fixedly installed on the main sliding frame 104. A moving motor 110 is fixedly installed on the main sliding frame 104. A motor gear 113 is fixedly installed on the motor shaft of the moving motor 110. A driving gear 111 is fixedly installed on the driving wheel 112, and the driving gear 111 meshes with the motor gear 113.

[0034] As Figures 4 - 6 shown, a placing cylinder 109 is fixedly installed on the main sliding frame 104. A plurality of bracket bases 4 are stacked in the placing cylinder 109. A pushing rod 114 is slidably installed on the main sliding frame 104. A bottom plate 116 is fixedly installed on the pushing rod 114. A pushing spring 115 is arranged between the pushing rod 114 and the main sliding frame 104. In the initial state, the bottom plate 116 is located below the placing cylinder 109.

[0035] As Figures 4 - 6 shown, the clamping module includes a movable plate 117 slidably installed on the main sliding frame 104. The movable plate 117 is fixedly installed with the pulling rope 107. A rotating shaft 118 is rotatably installed on the movable plate 117. A rotating rod 120 and a rotating gear 119 are fixedly installed on the rotating shaft 118. Two clamping rods 123 are slidably installed on the rotating rod 120. A clamping piece 121 is fixedly installed on the clamping rod 123. A clamping spring 122 is arranged between the clamping piece 121 and the rotating rod 120. A spreading block 124 is fixedly installed below the clamping piece 121.

[0036] The rotation of the moving motor 110 drives the rotation of the motor gear 113, which drives the rotation of the driving gear 111 and the driving wheel 112, thereby driving the movement of the pulling rope 107. The pulling rope 107 drives the movable plate 117 to slide along the main slide carriage 104. When the pulling rope 107 drives the movable plate 117 to slide towards the placement cylinder 109, when the rotating rod 120 contacts the pushing rod 114, it will push the pushing rod 114 and the bottom plate 116 to move outside the box, the pushing spring 115 is compressed, and the spreading block 124 contacts the placement rail 105. Under the action of the placement rail 105, the spreading block 124, the clamping piece 121 and the clamping rod 123 slide outwards, and the clamping spring 122 is stretched. When the clamping piece 121 moves below the placement cylinder 109, at this time the rotating rod 120 pushes the bottom plate 116 away from below the placement cylinder 109, and the bottommost support chassis 4 in the placement cylinder 109 falls onto the two clamping pieces 121. Subsequently, the pulling rope 107 drives the movable plate 117 to move away from the placement cylinder 109, and the pushing spring 115 gradually rebounds, causing the bottom plate 116 to return below the placement cylinder 109. The bottom plate 116 prevents the support chassis 4 in the placement cylinder 109 from falling out. When the spreading block 124 disengages from the placement rail 105, the clamping spring 122 rebounds, causing the two clamping pieces 121 to slide inwards, and the support chassis 4 is clamped by the clamping pieces 121. Subsequently, the movable plate 117 drives the support chassis 4 to reach beside the automatic welding torch 207.

[0037] As Figure 7 、 Figure 8 shown, the welding mechanism includes an electric cylinder 201 fixedly installed on the left frame 102. An extension frame 202 is fixedly installed on the output end of the electric cylinder 201. A fixed frame 205 is fixedly installed on the left frame 102. The electric cylinder 201 is fixedly installed with the right frame 103. The fixed frame 205 is fixedly installed with the right frame 103. A rack 203 is fixedly installed on the extension frame 202. A welding frame 204 is slidably installed on the fixed frame 205. An automatic welding torch 207 is fixedly installed on the welding frame 204. A welding spring 206 is provided between the welding frame 204 and the extension frame 202.

[0038] When the support chassis 4 reaches beside the automatic welding torch 207, the electric cylinder 201 extends to drive the extension frame 202 to move. The extension frame 202 pushes the welding frame 204 to slide relative to the fixed frame 205 through the welding spring 206, so that the automatic welding torch 207 contacts the parts to be welded of the support chassis 4 and the support rod 5. First, the support chassis 4 and the support rod 5 are spot-welded by the automatic welding torch 207. As the extension frame 202 continues to move, the rack 203 begins to mesh with the rotating gear 119. The rack 203 drives the rotating gear 119 and the rotating rod 120 to rotate, thereby driving the support chassis 4 to rotate. Since the automatic welding torch 207 has spot-welded the support chassis 4 and the support rod 5, at this time, the support chassis 4 and the support rod 5 rotate together. Finally, the rack 203 drives the rotating gear 119, the rotating rod 120, the support chassis 4 and the support rod 5 to rotate 360 degrees, and the automatic welding torch 207 automatically welds the support chassis 4 and the support rod 5 for a full circle. When the automatic welding torch 207 contacts the parts to be welded of the support chassis 4 and the support rod 5, as the extension frame 202 continues to move, the welding spring 206 will be compressed, and the automatic welding torch 207 remains in contact with the parts to be welded of the support chassis 4 and the support rod 5. After the support chassis 4 and the support rod 5 are welded, the pull rope 107 drives the movable plate 117 to move to the discharge rail 108. The spreading block 124 contacts the discharge rail 108. Under the action of the discharge rail 108, the spreading block 124, the clamping piece 121 and the clamping rod 123 are pushed to slide outwards, and the clamping spring 122 is stretched. At this time, the clamping piece 121 no longer clamps the support chassis 4, and the welded support chassis 4 and support rod 5 are removed manually.

[0039] As Figures 9 - 14 shown, the feeding mechanism includes an upper connecting frame 301 fixedly installed on the left frame 102 and the right frame 103. An upper frame 302 is fixedly installed on the upper connecting frame 301. A plurality of support rods 5 are placed on the upper frame 302. A feeding block 328 is slidably installed on the upper frame 302. A feeding spring 329 is arranged between the feeding block 328 and the upper frame 302. A lower fixed column 325 is fixedly installed on the upper frame 302. A lower pressing rod 327 is slidably installed on the lower fixed column 325. A lower spring 326 is arranged between the lower pressing rod 327 and the lower fixed column 325. A blocking triangular block 324 is fixedly installed on the lower pressing rod 327. A slope is arranged on the upper surface of the blocking triangular block 324. A plurality of support rods 5 are located between the feeding block 328 and the blocking triangular block 324. Two limiting frames 330 for limiting the support rods 5 are fixedly installed on the upper frame 302.

[0040] As Figures 9 - 14As shown in the figure, a top electric cylinder 303 is fixedly installed on the upper frame 302. A lifting plate 304 is fixedly installed on the output end of the top electric cylinder 303. A column 308 is fixedly installed on the upper frame 302. The lifting plate 304 is slidably installed with the column 308. An inner lifting column 305 is fixedly installed below the lifting plate 304. An outer lifting cylinder 306 is slidably installed on the inner lifting column 305. An inner spring 307 is arranged between the inner lifting column 305 and the outer lifting cylinder 306. A descending frame 309 is fixedly installed on the lifting plate 304. An upper column 310 is fixedly installed below the lifting plate 304. A lower frame 311 is slidably installed on the upper column 310. A compression spring 312 is arranged between the lower frame 311 and the upper column 310. Two ejecting cone blocks 313 are fixedly installed below the lower frame 311. Two slopes are arranged on the lower surface of the ejecting cone blocks 313. A slope is arranged above the support rod 5.

[0041] As Figures 9 - 14 shown in the figure, a motor 320 is fixedly installed on the upper frame 302. Two conveying wheels 321 are rotatably installed on the upper frame 302. The motor 320 drives the conveying wheels 321 to rotate through gear transmission. A conveyor belt 322 is wound around the two conveying wheels 321. A push plate 323 is fixedly installed on the conveyor belt 322.

[0042] As Figures 9 - 14 shown in the figure, an upper fixing frame 314 is fixedly installed on the upper frame 302. A descending rod 315 is slidably installed on the upper fixing frame 314. A descending spring 316 is arranged between the descending rod 315 and the upper fixing frame 314. A sliding column 318 is slidably installed on the descending rod 315. A descending plate 317 is fixedly installed on the sliding column 318. A sliding column spring 319 is arranged between the descending plate 317 and the descending rod 315.

[0043] When the support chassis 4 reaches beside the automatic welding torch 207, the top electric cylinder 303 contracts to drive the lifting plate 304, inner lifting column 305, outer lifting cylinder 306, lowering frame 309, upper column 310, lower frame 311 and ejecting cone 313 to lower. The outer lifting cylinder 306 presses down the support rod 5 located on the lowering plate 317. The outer lifting cylinder 306 presses down the support rod 5, lowering plate 317 and lowering rod 315 together, and the lowering spring 316 is stretched until the support chassis 4 is docked with the support rod 5. When the ejecting cone 313 descends to contact the two support rods 5 below it, at this time, the two slopes of the ejecting cone 313 contact the slopes of the two support rods 5 below the ejecting cone 313. At this time, the lowering frame 309 starts to contact the pressing rod 327. The lifting plate 304 continues to descend. Since the blocking triangular block 324 blocks the support rod 5 at this time, the ejecting cone 313 cannot push out the support rod 5 on its right side at this time, and the compression spring 312 is compressed. The lowering frame 309 pushes the pressing rod 327 and the blocking triangular block 324 to descend along the lower fixed column 325, and the lower spring 326 is compressed. When the blocking triangular block 324 descends a certain distance, it no longer blocks the support rod 5. At this time, the compression spring 312 rebounds and pushes the ejecting cone 313 downward, thereby pushing the support rod 5 on the right side of the ejecting cone 313 under the conveyor belt 322. At the same time, the support rod 5 on the left side of the ejecting cone 313 is pushed to the left, and the feeding spring 329 is further compressed. When the support rod 5 and the support chassis 4 are welded, after the support chassis 4 drives the support rod 5 to rotate 90 degrees, the support rod 5 leaves above the lowering plate 317. At this time, the top electric cylinder 303 extends, and the lowering rod 315 and the lowering plate 317 return to the initial position under the rebound of the lowering spring 316. The ejecting cone 313 and the lowering frame 309 rise, the lower spring 326 rebounds, so that the blocking triangular block 324 rises again, the feeding spring 329 rebounds, and the subsequent support rod 5 is pushed forward through the feeding block 328, so that the rightmost support rod 5 contacts the blocking triangular block 324. The motor 320 drives the conveyor wheel 321 to rotate through gear transmission, thereby driving the conveyor belt 322 to rotate. The support rod 5 is toggled above the lowering plate 317 through the push plate 323 to prepare for the next feeding, and so on.

[0044] The working principle of a VR bracket welding device for a VR classroom disclosed by the present invention is as follows: The moving motor 110 rotates to drive the motor gear 113 to rotate, driving the driving gear 111 and the driving wheel 112 to rotate, thereby driving the pull rope 107 to move. The pull rope 107 drives the movable plate 117 to slide along the main slide 104. When the pull rope 107 drives the movable plate 117 to slide towards the placing cylinder 109, when the rotating rod 120 contacts the push rod 114, it will push the push rod 114 and the bottom plate 116 to move out of the box. The push spring 115 is compressed, and the spreading block 124 contacts the placing rail 105. Under the action of the placing rail 105, the spreading block 124, the clamping piece 121 and the clamping rod 123 slide outwards, and the clamping spring 122 is stretched. When the clamping piece 121 moves below the placing cylinder 109, at this time the rotating rod 120 pushes the bottom plate 116 away from below the placing cylinder 109, and the bottommost bracket chassis 4 in the placing cylinder 109 falls onto the two clamping pieces 121. Subsequently, the pull rope 107 drives the movable plate 117 to move away from the placing cylinder 109, and the push spring 115 gradually rebounds, causing the bottom plate 116 to return below the placing cylinder 109. The bottom plate 116 prevents the bracket chassis 4 in the placing cylinder 109 from falling out. When the spreading block 124 disengages from the placing rail 105, the clamping spring 122 rebounds, causing the two clamping pieces 121 to slide inwards, and the bracket chassis 4 is clamped by the clamping pieces 121. Subsequently, the movable plate 117 drives the bracket chassis 4 to reach beside the automatic welding gun 207. When the bracket chassis 4 reaches beside the automatic welding gun 207, the top electric cylinder 303 contracts to drive the lifting plate 304, the inner lifting column 305, the outer lifting cylinder 306, the lowering frame 309, the upper column 310, the lower frame 311 and the ejecting cone 313 to descend. The outer lifting cylinder 306 presses down the bracket rod 5 located on the lowering plate 317. The outer lifting cylinder 306 presses down the bracket rod 5, the lowering plate 317 and the lowering rod 315 together, and the lowering spring 316 is stretched until the bracket chassis 4 is docked with the bracket rod 5. When the ejecting cone 313 descends to contact the two bracket rods 5 below it, at this time the two slopes of the ejecting cone 313 contact the slopes of the two bracket rods 5 below the ejecting cone 313. At this time, the lowering frame 309 starts to contact the pressing rod 327, and the lifting plate 304 continues to descend. Since the blocking triangular block 324 blocks the bracket rod 5 at this time, the ejecting cone 313 cannot push out the bracket rod 5 on its right side at this time. The compression spring 312 is compressed, and the lowering frame 309 pushes the pressing rod 327 and the blocking triangular block 324 to descend along the lower fixed column 325, and the lower spring 326 is compressed. When the blocking triangular block 324 descends a certain distance, it no longer blocks the bracket rod 5. At this time, the compression spring 312 rebounds, pushing the ejecting cone 313 downwards, and further pushing the bracket rod 5 on the right side of the ejecting cone 313 below the conveyor belt 322. At the same time, the bracket rod 5 on the left side of the ejecting cone 313 is pushed to the left, and the feeding spring 329 is further compressed. The electric cylinder 201 extends to drive the extending frame 202 to move.The extending frame 202 pushes the welding frame 204 to slide relative to the fixed frame 205 through the welding spring 206, so that the automatic welding gun 207 contacts the parts to be welded of the support chassis 4 and the support rod 5. First, the support chassis 4 and the support rod 5 are spot-welded by the automatic welding gun 207. As the extending frame 202 continues to move, the rack 203 begins to mesh with the rotating gear 119, and the rack 203 drives the rotating gear 119 and the rotating rod 120 to rotate, thereby driving the support chassis 4 to rotate. Since the automatic welding gun 207 has spot-welded the support chassis 4 and the support rod 5, at this time The frame chassis 4 and the support rod 5 rotate together, and finally the rack 203 drives the rotating gear 119, the rotating rod 120, the frame chassis 4 and the support rod 5 to rotate 360 degrees. After the frame chassis 4 drives the support rod 5 to rotate 90 degrees, the support rod 5 leaves the top of the descending plate 317. At this time, the top electric cylinder 303 extends, and the descending rod 315 and the descending plate 317 return to the initial position under the rebound of the descending spring 316. The ejector cone block 313 and the descending frame 309 rise, and the lower spring 326 rebounds, so that the blocking triangle block 324 rises again, and the feed spring 329 rebounds. The feeding block 328 pushes the subsequent support rod 5 forward, so that the rightmost support rod 5 contacts the blocking triangle block 324, and the motor 320 drives the conveying wheel 321 to rotate through the gear transmission, thereby driving the conveying belt 322 to rotate, and the support rod 5 is moved to the top of the descending plate 317 through the push plate 323 to prepare for the next feeding, and the automatic welding gun 207 automatically welds the support chassis 4 and the support rod 5 for a full circle. When the automatic welding gun 207 contacts the parts to be welded of the support chassis 4 and the support rod 5, the extension frame 202 continues to move, which will make The welding spring 206 is compressed, and the automatic welding gun 207 keeps in contact with the parts of the bracket chassis 4 and the bracket rod 5 to be welded. After the bracket chassis 4 and the bracket rod 5 are welded, the pull rope 107 moves the movable plate 117 to the discharge rail 108, and the opening block 124 contacts the discharge rail 108. Under the action of the discharge rail 108, the opening block 124, the clamping piece 121 and the clamping rod 123 are pushed to slide outward, and the clamping spring 122 is stretched. At this time, the clamping piece 121 no longer clamps the bracket chassis 4, and the welded bracket chassis 4 and the bracket rod 5 are manually removed.
