Description

Technical Field

[0001] The present invention belongs to the technical field of IBC tote production, and particularly relates to an automatic production line for IBC totes. Background Art

[0002] IBC totes have the advantages of light weight, high strength, corrosion resistance, etc., and are widely used in industries such as chemical industry, medicine, food, coatings, etc. They are essential tools for modern warehousing and transporting liquid products. An IBC tote is assembled from an inner container, i.e., an inner liner, and an external metal outer frame. The inner liner is blow-molded from high molecular weight high-density polyethylene, with high strength, corrosion resistance, and good hygiene. Wrapping the outer frame around the inner liner can make the IBC tote safer and more reliable during use.

[0003] When processing existing IBC totes, generally, components such as the inner liner, the frame and chassis of the outer frame are processed separately. After processing, they are separately transferred to the assembly equipment for unified assembly. The entire processing process cannot form a systematic structure, thus prolonging the production time of IBC totes and reducing production efficiency. Summary of the Invention

[0130] Among them, the mesh is welded by multiple short pipes and long pipes. That is, the pipe placement mechanism 4 grabs short pipes from the short pipe feeding mechanism 2, grabs long pipes from the long pipe feeding mechanism 3, and places the two kinds of pipes on the mesh welding mechanism 1 according to the set positions, and the mesh welding mechanism 1 welds the pipes into a mesh structure.

[0131] After the mesh welding is completed, it is sequentially transferred to the bending mechanism 9, the socketing mechanism 5 and the pressing and punching mechanism 10. Among them, the bending mechanism 9 bends the mesh into the shape of a mesh frame, the socketing mechanism 5 inserts and fixes the ends of the mesh frame crossbeams formed after bending the long pipes, and the pressing and punching mechanism 10 is to flatten and punch through holes at the corners of the mesh frame crossbeams at the bottom layer of the mesh frame to facilitate subsequent connection to the chassis.

[0132] After the various parts of the chassis are manually loaded on the chassis feeding mechanism 6, they are automatically transferred to the chassis welding mechanism 11 to weld the various parts together, and the welded chassis semi-finished product is transferred to the chassis flipping mechanism 7 to flip it 180 degrees to facilitate the installation of the bottom plate on the chassis semi-finished product, and then the chassis is processed and formed.

[0133] The chassis and the mesh frame are assembled to form an outer frame, and the outer frame is assembled with the inner tank to form a ton barrel structure.

[0134] As Figure 2 - 3 shown, the short pipe feeding mechanism 2 is used for feeding short pipes. It is arranged on one side of the mesh welding mechanism 1, and the moving direction of its pipes is parallel to the moving direction of the pipes on the mesh welding mechanism 1.

[0135] Specifically, the short pipe feeding mechanism 2 successively includes a bin I 2-1, a feeding chain I 2-2, a transition frame I 2-3, a material transfer component I, and a discharging rack 2-4.

[0136] The feeding chain I 2-2 picks up short pipe materials from the bin I 2-1 and transfers them to the transition frame I 2-3. The short pipe materials fall from the transition frame I 2-3 to the material transfer component I, and the material transfer component I transfers the short pipe materials to the discharging rack 2-4.

[0137] In the short pipe feeding mechanism 2 of this embodiment, the end where the discharging rack 2-4 is located is its front end, that is, the short pipe materials move forward on this mechanism. Therefore, the bin I 2-1, the feeding chain I 2-2, the transition frame I 2-3, the material transfer component I, and the discharging rack 2-4 are arranged in sequence from the back to the front. And after the short pipe materials are removed from the bin I 2-1, they are successively transferred to the discharging rack 2-4 through the feeding chain I 2-2, the transition frame I 2-3, and the material transfer component I, and then can be grabbed by the pipe placing mechanism 4 and transferred to the mesh welding mechanism 1.

[0138] The bin I 2-1 is arranged on a bin support I 2-5, and its rear side is open, which is convenient for adding pipe materials into the bin I 2-1.

[0139] In order to facilitate the movement of the short pipe materials towards the discharge port of the bin I 2-1, the bottom plate I of the bin I 2- is inclined downward towards one end of its discharge port, and the inclination angle of the bottom plate I is adjustable.

[0140] The discharge port of the bin I 2-1 is located at its front end, and a front baffle is arranged above the discharge port. A support shaft 2-6 is arranged on the front side below the bottom plate I, and the bottom plate I can rotate relative to the support shaft 2-6.

[0141] Specifically, both ends of the support shaft 2-6 are fixed on the bin support I 2-5 through bearing seats, while both sides of the bottom plate I are fitted on the support shaft 2-6 through connecting plates that extend downward and have bayonets, that is, the bayonets are stuck on the support shaft 2-6, and the bottom plate I can rotate its inclination angle relative to the support shaft 2-6.

[0142] And in order to provide power for the angle adjustment of the bottom plate I, a lifting cylinder 2-7 is arranged below the bin I 2-1. The bottom of the lifting cylinder 2-7 is installed on the bin support I 2-5 through a lower hinge seat, and the top of its piston rod is connected to the bottom plate I through an upper hinge seat. Through the telescopic movement of the piston rod and in cooperation with the support shaft 2-6, the adjustment of the inclination angle of the bottom plate I is realized.

[0143] Preferably, arc-shaped waist-shaped holes are respectively arranged on the two side plates of the bin I 2-1, and the inclination angle of the front baffle of the bin I 2-1 can be adjusted through these waist-shaped holes.

[0144] Preferably, the front end of the base plate I is provided with a transition plate that cooperates with it and is arranged obliquely, and both ends of the front side of the transition plate are provided with avoidance gaps I that cooperate with the feeding chain I2-2.

[0145] The short pipe placed in the silo Ⅰ2-1 slides toward its discharge port and then falls onto the transition plate. At this time, the loading chain Ⅰ2-2 passing through the avoidance gap Ⅰ can pick up the short pipe and then move the pipe forward.

[0146] In order to be able to take out the short pipes from the discharge port of the silo I2-1, at least two feeding chains I2-2 are provided and arranged side by side at the discharge port of the silo I2-1.

[0147] In this embodiment, two feeding chains Ⅰ2-2 are provided to ensure the stability of the short pipes on the feeding chains Ⅰ2-2.

[0148] In order to realize the installation of the feeding chain Ⅰ2-2, the feeding chain Ⅰ2-2 is installed on two sprocket shafts Ⅰ2-8 arranged upper and lower and parallel to each other, and a feeding motor Ⅰ2-9 connected to one of the sprocket shafts Ⅰ2-8 is installed at the bottom of the silo Ⅰ2-1.

[0149] Specifically, the two ends of the two sprocket shafts Ⅰ2-8 are respectively installed on the silo bracket Ⅰ2-5 through bearings, and each sprocket shaft Ⅰ2-8 is provided with a sprocket Ⅰ near its end. The same feeding chain Ⅰ2-2 is assembled on the two sprockets Ⅰ on the same side of the two sprocket shafts Ⅰ2-8, and the feeding chain Ⅰ2-2 is driven to rotate by the rotation of the sprocket shaft Ⅰ2-8.

[0150] The feeding motor Ⅰ2-9 is used to provide power for the rotation of the feeding chain.

[0151] Specifically, the feeding motor Ⅰ2-9 is fixed to the silo bracket Ⅰ2-5 through the motor seat, and a driving sprocket Ⅰ is installed on its output shaft, and a driven sprocket Ⅰ is installed on the sprocket shaft Ⅰ2-8 located below. The driving sprocket Ⅰ and the driven sprocket Ⅰ are connected by a transmission chain Ⅰ (not shown in the figure), so that the feeding motor Ⅰ2-9 can drive the sprocket shaft Ⅰ2-8 below to rotate, and then cooperate with the sprocket shaft Ⅰ2-8 above to realize the rotation of the feeding chain Ⅰ2-2.

[0152] In order to be able to pick up short pipes, a plurality of loading blocks Ⅰ2-10 are installed on the loading chain Ⅰ2-2, and a picking trough Ⅰ2-11 is opened on the loading block Ⅰ2-10.

[0153] Specifically, an outwardly extending mounting plate I is provided on the outer link of the feeding chain I2-2, and the feeding block I2-10 is fixed on the mounting plate I.

[0154] Preferably, the pick-up chute I 2-11 is an arc chute, and the opening of the pick-up chute facing the side of the bin I 2-1 is upward, so as to ensure that the short pipes are stably placed in the pick-up chute I 2-11.

[0155] In order to move the short pipes on the feeding chain I 2-2 to the transfer assembly I, the transition frame I 2-3 is arranged on the side of the feeding chain I 2-2 away from the bin I 2-1, and the end away from the feeding chain I 2-2 is inclined downward.

[0156] Among them, the rear end of the transition frame I 2-3 is arranged side by side with the feeding chain I 2-2, and the front end extends towards the transfer assembly I. After the feeding chain I 2-2 passes over the sprocket I, the pick-up chute I 2-11 thereof turns over, that is, the opening faces downward, and the short pipes located on the pick-up chute I 2-11 directly fall onto the transition frame I 2-3, and then slide onto the transfer assembly I through the inclined transition frame I 2-3.

[0157] In this embodiment, there are two transition frames I 2-3 arranged side by side and are respectively located outside the two feeding chains I 2-2.

[0158] In order to control the short pipes on the transition frame I 2-3, a baffle 2-12 is arranged on one side of the lower end of the transition frame I 2-3, and a liftable ejector plate 2-13 is arranged on the other side.

[0159] Among them, the baffle 2-12 is used to block the random sliding of the short pipes on the transition frame I 2-3, and the setting of the ejector plate 2-13 can lift the short pipes located at the frontmost side on the transition frame I 2-3 one by one, making them higher than the baffle 2-12, so as to fall onto the transfer assembly I.

[0160] Specifically, the baffle 2-12 is arranged on the outer side of the front end of the transition frame I 2-3, and the ejector plate 2-13 is arranged on the inner side of the front end of the transition frame I 2-3. A ejector cylinder 2-14 for driving its lifting is arranged below it. Through the telescopic movement of the piston rod of the ejector cylinder 2-14, the lifting of the ejector plate 2-13 is driven.

[0161] Preferably, the upper edges of the baffle 2-12 and the ejector plate 2-13 are both structures with the front side inclined downward, which is convenient for the short pipes to fall onto the transfer assembly I along the upper edges of the two.

[0162] In order to prevent the short pipes on the transition frame I 2-3 from being stacked in multiple layers, a limit cover plate 2-15 is arranged above the transition frame I 2-3.

[0163] The transfer assembly I is installed on the transfer bracket I 2-16, and the transfer bracket I 2-16 is connected to the bin bracket I 2-5.

[0164] To achieve the forward movement of short pipes, the material transfer assembly I includes a fixed material transfer plate 2-17 arranged oppositely, and a movable material transfer plate 2-18 arranged inside the fixed material transfer plate 2-17 and capable of swinging between the transition rack I 2-3 and the feeding rack 2-4.

[0165] The movable material transfer plate 2-18 swings forward cyclically to continuously move the short pipes placed on the fixed material transfer plate 2-17 forward.

[0166] To achieve the gradual forward movement of short pipes on the material transfer assembly I, a plurality of material transfer grooves I 2-19 are provided on the upper edge of the fixed material transfer plate 2-17, and a material transfer groove II 2-20 cooperating with the material transfer groove I 2-19 is provided on the upper edge of the movable material transfer plate 2-18.

[0167] The material transfer grooves are used to temporarily place short pipes during the transfer process.

[0168] Specifically, when the movable material transfer plate 2-18 swings to the rearmost side, the material transfer grooves II 2-20 are arranged in one-to-one correspondence with the material transfer grooves I 2-19. When the movable material transfer plate 2-18 swings to the foremost side, the material transfer groove II 2-20 is opposite to the previous material transfer groove I 2-19. In this way, through the swing of the movable material transfer plate 2-18, the short pipes in the material transfer groove I 2-19 can be continuously moved forward until they are moved onto the feeding rack 2-4.

[0169] The forward and backward swing stroke of the movable material transfer plate 2-18 is the distance between two adjacent material transfer grooves on the same material transfer plate.

[0170] To achieve the forward and backward swing of the movable material transfer plate 2-18 in the material transfer assembly I, a material transfer motor I 2-23 is arranged between the two movable material transfer plates 2-18. The output end of the material transfer motor I 2-23 is connected with a cam 2-24. A swing plate 2-25 is connected to the cam 2-24. The swing plate 2-25 is connected with a swing frame 2-26. The two movable material transfer plates 2-18 are respectively installed at both ends of the swing frame 2-26.

[0171] The material transfer motor I 2-23 is fixed on the material transfer support I 2-16 through a motor seat. Its output shaft is connected with the protruding part of the cam 2-24, and the center of the cam 2-24 is connected with the swing plate 2-25. When the material transfer motor I 2-23 rotates one circle, it can drive the movable material transfer plate 2-18 to swing forward and backward once. That is, when the movable material transfer plate 2-18 swings forward, it moves in the forward and upward direction, and can move the short pipes on the fixed material transfer plate 2-17 forward. When it swings backward, it moves in the downward and backward direction to avoid touching the short pipes on the fixed material transfer plate 2-17.

[0172] The swing frame 2-26 includes two cross bars installed above the swing plate 2-25, and end plates arranged at both ends of the cross bars. The movable material transfer plate 2-18 is installed above the end plates.

[0173] The blanking rack 2-4 is arranged on the front side of the material transfer support I 2-16. The material transfer groove II 2-20 at the foremost side of the movable material transfer plate 2-18 can transfer the short pipe materials located on the foremost material transfer groove I 2-19 to the blanking rack 2-4.

[0174] To facilitate the placement of short pipe materials, two parallel blanking conveyor belts 2-27 are arranged on the blanking rack 2-4. A plurality of blanking blocks 2-28 are installed on the blanking conveyor belts 2-27, and blanking grooves 2-29 are formed in the blanking blocks 2-28.

[0175] To realize the rotation of the blanking conveyor belts 2-27, the driving pulleys of the blanking conveyor belts 2-27 are located at one end of the blanking rack 2-4 away from the material transfer assembly I. A blanking conveyor motor 2-30 is connected to the outside of one of the blanking conveyor belts 2-27, and the driving pulleys of the two blanking conveyor belts 2-27 are connected by a synchronous shaft.

[0176] The blanking conveyor motor 2-30 drives the two driving pulleys to rotate, thereby realizing the synchronous movement of the two blanking conveyor belts 2-27.

[0177] To align the two ends of the short pipe materials on the blanking rack 2-4, pusher blocks 2-21 which are arranged oppositely and can move inwards or outwards are installed on the outside of the two blanking conveyor belts 2-27.

[0178] A pusher cylinder 2-22 for driving the pusher block 2-21 to move is installed on the outside of the pusher block 2-21.

[0179] When the short pipe materials move between the two pusher blocks 2-21 driven by the blanking conveyor belts 2-27, the two pusher blocks 2-21 move towards each other under the action of the pusher cylinder 2-22, so as to limit and align the two ends of the short pipe materials, and realize the alignment of the ends of each short pipe material.

[0180] As Figure 4 - 6 shown, the long pipe feeding mechanism 3 is used for the feeding of long pipe materials. It is arranged on the other side of the mesh welding mechanism 1, and the moving direction of its pipe materials is perpendicular to the moving direction of the pipe materials on the mesh welding mechanism 1.

[0181] Specifically, the long pipe feeding mechanism 3 successively includes a bin II 3-1, a feeding chain II 3-2, a transition rack II 3-3, a material transfer assembly II, and a conveying track I 3-4.

[0182] The feeding chain II 3-2 picks up the long pipe materials from the bin II 3-1 and transfers them to the transition rack II 3-3. The long pipe materials fall onto the material transfer assembly II through the transition rack II 3-3, and the long pipe materials are transferred to the conveying track I 3-4 through the material transfer assembly II.

[0183] In the long tube feeding mechanism 3 of this embodiment, the end of the conveyor belt I 3-4, i.e., the end facing the mesh welding mechanism 1, is the front end, and the long tube moves forward on the mechanism. Therefore, in the long tube feeding mechanism 3, the hopper II 3-1, the feeding chain II 3-2, the transition frame II 3-3, the material transfer assembly II, and the conveyor belt I 3-4 are arranged in sequence from back to front. The long tube passes through the feeding chain II 3-2, the transition frame II 3-3, and the material transfer assembly II in sequence, and is transferred to the conveyor belt I 3-4. The long tube continues to move forward along the conveyor belt I 3-4, so that it can be grabbed by the subsequent tube placement mechanism 4.

[0184] In order to enable the long pipe to move toward the discharge port of the silo II 3 - 1 , the bottom plate II of the silo II 3 - 1 is tilted downward toward one end of the discharge port.

[0185] The silo II 3-1 is fixed on the silo bracket II 3-5. The front side of the silo II 3-1 is opened to form its discharge port. The long pipe is placed horizontally in the silo and can slide toward the discharge port. When the loading chain II 3-2 passes through the discharge port of the silo II 3-1, it picks up the long pipe from the silo II 3-1.

[0186] In order to ensure the stability of the long pipe following the movement of the feeding chain II3-2, at least two feeding chains II3-2 are provided and arranged side by side at the discharge port of the silo II3-1.

[0187] In this embodiment, two feeding chains II 3 - 2 are provided, and an avoidance gap II is provided on the front side of the bottom plate II to facilitate the passage of the feeding chain II 3 - 2 and thus pick up the long pipe.

[0188] In order to realize the installation and rotation of the feeding chain Ⅱ3-2, the feeding chain Ⅱ3-2 is installed on two sprocket shafts Ⅱ3-6 arranged upper and lower and parallel to each other, and a feeding motor Ⅱ3-7 connected to one of the sprocket shafts Ⅱ3-6 is installed below the silo Ⅱ3-1.

[0189] Specifically, the two ends of the two sprocket shafts Ⅱ3-6 are respectively installed on the silo bracket Ⅱ3-5 through bearings, and each sprocket shaft Ⅱ3-6 is provided with a sprocket Ⅱ near its end. The same feeding chain Ⅱ3-2 is assembled on the two sprockets Ⅱ on the same side of the two sprocket shafts Ⅱ3-6, and the feeding chain Ⅱ3-2 is driven to rotate by the rotation of the sprocket shaft Ⅱ3-6.

[0190] The feeding motor Ⅱ3-7 is fixed on the silo bracket Ⅱ3-5 through the motor seat and is located below the silo Ⅱ3-1. The driving sprocket Ⅱ is installed on its output shaft, and the driven sprocket Ⅱ is installed on the sprocket shaft Ⅱ3-6 located below. The driving sprocket Ⅱ and the driven sprocket Ⅱ are connected by the transmission chain Ⅱ. The feeding motor Ⅱ3-7 can drive the rotation of the lower sprocket shaft Ⅱ3-6, and then cooperate with the upper sprocket shaft Ⅱ3-6 to realize the rotation of the feeding chain Ⅱ3-2.

[0191] In order to facilitate the picking up of long pipes, a plurality of loading blocks II3-8 are installed on the loading chain II3-2, and a picking trough II3-9 is opened on the loading block II3-8.

[0192] Specifically, the structure of the feeding chain II3-2 is the same as that of the feeding chain I2-2, and the operation modes of the two are also the same. In addition, the structure of the feeding block II3-8 is the same as that of the feeding block I2-10.

[0193] In order to move the long pipes on the feeding chain Ⅱ3-2 to the material transfer component Ⅱ, at least two transition racks Ⅱ3-3 are provided and arranged in parallel on the side of the feeding chain Ⅱ3-2 away from the silo Ⅱ3-1, and the end of the transition rack Ⅱ3-3 facing the material transfer component Ⅱ is tilted downward, and the end facing the feeding chain Ⅱ3-2 is tilted upward.

[0194] After the feeding chain Ⅱ3-2 passes the upper sprocket Ⅱ, its picking trough Ⅱ3-9 is reversed, that is, the opening faces downward, and the long pipe on the picking trough Ⅱ3-9 falls directly onto the transition frame Ⅱ3-3, and then passes through the inclined transition frame Ⅱ3-3 and slides onto the material transfer component Ⅱ.

[0195] In order to achieve the continued forward movement of the long pipe, at least two material transfer assemblies II are provided and arranged side by side on the side of the transition frame II 3-3 facing the conveyor track I 3-4. The material transfer assembly II includes a material transfer belt 3-10.

[0196] The material moving component II is installed on the material moving bracket II 3-12, and the front side of the material moving bracket II 3-12 is connected to the silo bracket II 3-5.

[0197] In order to realize the installation and rotation of the material transfer belt 3-10, the material transfer component II also includes a mounting frame 3-13, and a material transfer motor II 3-14 capable of driving the material transfer belt 3-10 to rotate is installed below the mounting frame 3-13.

[0198] In this embodiment, two material transfer assemblies II are provided, and two mounting brackets 3-13 are fixed to the ends of the material transfer bracket II 3-12, respectively. This ensures that both ends of the long pipe move forward synchronously and prevents the pipe from tilting. The material transfer belt 3-10 passes over multiple pulleys, forming a flat upper portion. The long pipe falls onto the top of the material transfer belt 3-10 and continues to move forward under the drive of the material transfer belt 3-10 until it is transferred to the conveyor track I 3-4.

[0199] Transfer belt

[0200] The material transfer motor II 3-14 is used to drive the material transfer belt 3-10 to rotate.

[0201] In this embodiment, two material transfer belts 3-10 are arranged side by side on each material transfer assembly II, and the two material transfer belts 3-10 pass around the rotating shaft, and the material transfer motor II 3-14 is connected to the rotating shaft through the pulley assembly to drive the two material transfer belts 3-10 to rotate synchronously.

[0202] Preferably, the lower portion of the material transfer belt 3-10 is passed around the bottom of a tensioning wheel, and the tensioning wheel is installed on a tensioning frame and can be adjusted up and down on the tensioning frame to achieve tension adjustment of the material transfer belt 3-10.

[0203] The long pipe moves onto the conveyor crawler I 3-4 and continues to move forward along the conveyor crawler I 3-4 until it moves to the front end of the conveyor crawler I 3-4, where it can be grabbed by the pipe placement mechanism 4. Therefore, the conveyor crawler I 3-4 is arranged on the side of the material transfer component II away from the transition frame II 3-3, and the end of the conveyor crawler I 3-4 away from the material transfer component II is tilted downward.

[0204] The conveying crawler belt I3-4 is installed on the conveying bracket 3-15, and the front side of the material moving bracket II3-12 is connected to the conveying bracket 3-15.

[0205] Silo II 3-1 is used for loading long pipes. The outer width of some ton barrels also requires a small amount of medium and long pipes, that is, pipes that are shorter than long pipes and longer than short pipes. In order to realize the loading of such medium and long pipes, silo III 3-22 is installed above silo II 3-1. The bottom plate III of silo III 3-22 is tilted downward toward one end of its discharge port. A conveyor belt II 3-23 is provided on the discharge port side of silo III 3-22, which is located above the conveyor belt I 3-4. The end of the conveyor belt II 3-23 away from silo III 3-22 is tilted downward.

[0206] The silo III3-22 is fixed on the top of the silo bracket II3-5 through the silo bracket III3-24. The silo III3-22 can be divided into multiple parts according to the length of the medium and long pipes. In this embodiment, the silo III3-22 is divided into two parts, and the conveyor track II3-23 is divided into two groups, corresponding to the two silos III3-22 respectively.

[0207] A retaining bar is provided at the discharge port of the storage bin Ⅲ 3-22, which can prevent medium and long pipes from falling. During loading, medium and long pipes can be manually taken from the storage bin Ⅲ 3-22 and directly placed on the conveying track Ⅱ 3-23 in the correct direction one by one, and the conveying track Ⅱ 3-23 is used to drive them forward.

[0208] To drive the rotation of the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23, the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 are installed on the conveying support 3-15, and a conveying motor 3-25 that can drive the rotation of the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 respectively is installed on the side of the conveying support 3-15.

[0209] The conveying support 3-15 is divided into two layers. The upper layer is used to install the conveying track Ⅱ 3-23, and the lower layer is used to install the conveying track Ⅰ 3-4.

[0210] Among them, the conveying motor 3-25 drives the corresponding conveying track to rotate through the transmission shaft 3-26 connected thereto.

[0211] Specifically, the driving track wheel at the front end of the conveying track Ⅰ 3-4 is installed on a transmission shaft Ⅰ, and one end of the transmission shaft Ⅰ is connected to a conveying motor Ⅰ.

[0212] The driving track wheel at the front end of the conveying track Ⅱ 3-23 is installed on a transmission shaft Ⅱ, and one end of the transmission shaft Ⅱ is connected to a conveying motor Ⅱ.

[0213] To facilitate lifting the pipes for the pipe placement mechanism 4 to grab, a lifting seat 3-27 that can move up and down corresponding to the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 respectively is installed at one end of the conveying support 3-15 away from the material transfer assembly Ⅱ.

[0214] A lifting cylinder 3-28 for controlling its lifting is provided below the lifting seat 3-27.

[0215] Specifically, a plurality of lifting cylinders Ⅰ are installed at the front end of the lower-layer conveying support 3-15. A lifting seat Ⅰ is installed at the top of the piston rod of the lifting cylinder Ⅰ. By extending the piston rod, the longest pipe on the conveying track Ⅰ 3-4 can be lifted up to facilitate the pipe placement mechanism 4 to grab.

[0216] A plurality of lifting cylinders Ⅱ are installed at the front end of the lower-layer conveying support 3-15. A lifting seat Ⅱ is installed at the top of the piston rod of the lifting cylinder Ⅱ. By extending the piston rod, the medium and long pipes on the conveying track Ⅱ 3-23 can be lifted up to facilitate the pipe placement mechanism 4 to grab.

[0217] In addition, the front end of the conveying track Ⅰ 3-4 is staggered from the front end of the conveying track Ⅱ 3-23, that is, the conveying track Ⅰ 3-4 is longer than the conveying track Ⅱ 3-23, which can avoid the interference of the conveying track Ⅱ 3-23 on the lifting of the lifting seat Ⅰ.

[0218] One side of the long pipe is provided with an arc groove. When loading, it is necessary to ensure that the direction of its arc groove is downward. Subsequently, the pipe placing mechanism 4 grabs and directly places it on the mesh welding structure.

[0219] Preferably, workpiece in-place detection parts 3-16 with the detection head facing backward are installed on at least one lifting seat Ⅰ and at least one lifting seat Ⅱ to detect whether there is a pipe on the lifting seat 3-27; a side frame is arranged on one side of the lifting seat 3-27, and a workpiece direction detection part 3-17 is installed on the side frame to detect whether the placing direction of the pipe is accurate.

[0220] Specifically, when the workpiece in-place detection part 3-16 emits light and the workpiece direction detection part 3-17 does not emit light, it means that there is a pipe with the correct placing direction on the lifting seat 3-27. At this time, the lifting seat 3-27 can be raised according to the instruction to facilitate the pipe placing mechanism 4 to grab the pipe. When the workpiece in-place detection part 3-16 does not emit light and the workpiece direction detection part 3-17 does not emit light, it indicates that there is no pipe on the lifting seat 3-27; when the workpiece in-place detection part 3-16 emits light and the workpiece direction detection part 3-17 emits light, it indicates that the placing direction of the pipe is incorrect.

[0221] The workpiece in-place detection part 3-16 and the workpiece direction detection part 3-17 can be selected but not limited to infrared induction probes.

[0222] When a pipe with an incorrect placing direction is detected, it needs to be ejected. Therefore, a ejecting seat 3-18 corresponding to the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 and capable of moving up and down is installed at the end of the conveying support 3-15 far away from the material transfer component Ⅱ.

[0223] A lifting cylinder 3-19 for controlling its lifting is arranged below the ejecting seat 3-18.

[0224] Specifically, a lifting cylinder Ⅰ is installed at the front end of the lower-layer conveying support 3-15, and the ejecting seat Ⅰ is installed at the upper end of the piston rod of the lifting cylinder Ⅰ to eject the long pipe with an incorrect direction on the conveying track Ⅰ 3-4.

[0225] A lifting cylinder Ⅱ is installed at the front end of the upper-layer conveying support 3-15, and the ejecting seat Ⅱ is installed at the upper end of the piston rod of the lifting cylinder Ⅱ to eject the medium-length pipe with an incorrect direction on the conveying track Ⅱ 3-23.

[0226] Preferably, the top stock seat 3-18 is of a U-shaped structure, and its upper edge is a bevel structure with the front lower and the rear higher, which can make the pipe fall to the front side of the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 when the pipe is ejected.

[0227] In order to be able to receive the pipes ejected by the top stock seat 3-18, waste racks 3-11 located respectively below the conveying track Ⅰ 3-4 and the conveying track Ⅱ 3-23 are installed at one end of the conveying support 3-15 far from the material transfer assembly Ⅱ.

[0228] A plurality of waste racks Ⅰ are installed side by side at the front end of the lower-layer conveying support 3-15 for receiving the pipes ejected by the top stock seat Ⅰ; a plurality of waste racks Ⅱ are installed side by side at the front end of the upper-layer conveying support 3-15 for receiving the pipes ejected by the top stock seat Ⅱ.

[0229] Preferably, baffles 3-29 and alignment plates 3-20 for aligning the two ends of the pipe are arranged on both sides of the conveying support 3-15, and an alignment cylinder 3-21 for controlling the inward or outward movement of the alignment plate 3-20 is arranged outside the alignment plate 3-20.

[0230] Specifically, baffles Ⅰ are arranged on both sides of the lower-layer conveying support 3-15, and the upper-layer conveying support 3-15 is provided with baffles Ⅱ located on both sides of each group of upper conveying tracks to prevent the pipes from falling off the conveying support 3-15.

[0231] An alignment plate Ⅰ is arranged at the front end of one of the baffles Ⅰ, and an alignment cylinder Ⅰ located outside the alignment plate Ⅰ and used to push the alignment plate Ⅰ to move in and out is provided. The front end of the other baffle Ⅰ extends forward and can cooperate with the alignment plate Ⅰ to facilitate adjusting the left and right positions of the pipes on the conveying track so that their two ends are aligned.

[0232] And for the grouped baffles Ⅱ, an alignment plate Ⅱ is arranged at the front end of the outer baffle Ⅱ, and an alignment cylinder Ⅱ is arranged outside the alignment plate Ⅱ. The front end of the inner baffle Ⅱ extends forward and can cooperate with the alignment plate Ⅱ to facilitate adjusting the left and right positions of the pipes on the upper conveying track so that their two ends are aligned.

[0233] As Figure 7 - 10 shown, the function of the pipe placement mechanism 4 is to place the pipes on the long pipe feeding mechanism 3 and the short pipe feeding mechanism 2 onto the mesh welding mechanism 1 to weld a plurality of individual pipes into a mesh structure.

[0234] Specifically, the pipe placement mechanism 4 includes a material placement rack 4-1, and a short pipe placement assembly and a long pipe placement assembly which are installed on the material placement rack 4-1 and can traverse on the material placement rack 4-1.

[0235] The stock rack 4-1 straddles the mesh welding mechanism 1, and both the short pipe stock component and the long pipe stock component are arranged perpendicular to the direction of the stock rack 4-1. In the pipe stock mechanism 4 of this embodiment, the direction of the stock rack 4-1 is taken as the transverse direction, and the length directions of the short pipe stock component and the long pipe stock component are taken as the longitudinal direction.

[0236] Therefore, in order to realize the cooperation between the pipe stock mechanism 4, the long pipe feeding machine structure and the short pipe feeding mechanism 2, the stock rack bases on the side where the long pipe stock component is located are on both sides of the front end of the long pipe feeding mechanism 3, and the short pipe feeding mechanism 2 is located inside the stock rack 4-1. Among them, the short pipe stock component grabs the short pipes from the short pipe feeding mechanism 2 and places them on the mesh welding mechanism 1, and the long pipe stock component grabs the long pipes from the long pipe feeding mechanism 3 and places them on the mesh welding mechanism 1.

[0237] For the feeding of short pipes, the blanking rack 2-4 is located below the stock rack 4-1. When the number of short pipes on the blanking rack 2-4 is equal to the number required for the outer frame, the short pipe stock component grabs all the short pipes to realize the one-time feeding of short pipes. To achieve this effect, the short pipe stock component includes a stock sliding carriage I 4-2 that can traverse on the stock rack 4-1, and a stock seat I that is installed below the stock sliding carriage I and can be lifted and lowered. A number of short pipe positioning plates 4-3 are installed at the bottom of the stock seat I, and a pick-up plate 4-4 that cooperates with the short pipe positioning plates 4-3 and is located inside the short pipe positioning plates 4-3.

[0238] Among them, the stock sliding carriage I 4-2 can reciprocate between the blanking rack 2-4 and the mesh welding mechanism 1 to realize the feeding of short pipes.

[0239] When feeding short pipes, the stock sliding carriage I 4-2 moves above the blanking rack 2-4. When the stock seat I moves down above the short pipes, the pick-up plate 4-4 longitudinally translates towards the side of the corresponding short pipe, and then the stock seat I continues to move down. When the pick-up plate 4-4 moves down below the side of the short pipe and the short pipe positioning plates 4-3 respectively cooperate with each short pipe for positioning, the pick-up plate 4-4 longitudinally translates towards the corresponding short pipe. At this time, the short pipes are respectively located in each pick-up plate 4-4. At this time, the stock seat I rises, and the short pipes are transferred above the mesh welding mechanism 1 by using the movement of the stock sliding carriage I 4-2. Then the stock seat I descends, and the pick-up plate 4-4 longitudinally translates out from below the short pipes, and the short pipes can be placed on the mesh welding mechanism 1.

[0240] In order to achieve the grasping of short pipes through the movement of the picking plate 4-4, the material placing seat I includes a fixed material placing seat 4-5 and a movable material placing seat 4-6 arranged below the fixed material placing seat 4-5 and capable of moving in the length direction of the fixed material placing seat 4-5. The picking plate 4-4 is fixed to the bottom of the movable material placing seat 4-6, and the short pipe positioning plate 4-3 is installed on the outside of the fixed material placing seat 4-5.

[0241] In order to achieve the translation of the picking plate 4-4, a translation cylinder 4-7 is installed on the movable material placing seat 4-6, and the piston rod of the translation cylinder 4-7 is connected to the fixed material placing seat 4-5.

[0242] The telescopic direction of the translation cylinder 4-7 is parallel to the length direction of the movable material placing seat 4-6, that is, in the longitudinal direction. By the telescopic movement of the piston rod of the translation cylinder 4-7, the translation of the movable material placing seat 4-6 relative to the fixed material placing seat 4-5 is achieved.

[0243] In order to achieve the positioning and grasping of short pipes, a positioning notch 4-8 is provided at the bottom of the short pipe positioning plate 4-3, and the picking plate 4-4 is a Z-shaped plate.

[0244] During positioning, the short pipe is fitted in the positioning notch 4-8, and the Z-shaped picking plate 4-4 can not only achieve the grasping of the pipe, but also facilitate the assembly with the movable material placing seat 4-6.

[0245] Preferably, a magnetic part is provided on the inner wall of the picking opening of the picking plate 4-4, which can ensure the stability of the grasping and movement of the short pipe. When the short pipe is disengaged from the picking plate 4-4, the short pipe positioning plate 4-3 can also prevent the short pipe from being removed along with the picking plate 4-4.

[0246] In order to achieve the lifting of the material placing seat I, a lifting cylinder I 4-9 is installed on the material placing slide I 4-2, and the lower end of the piston rod of the lifting cylinder I 4-9 is connected to the material placing seat I.

[0247] Specifically, the lower end of the piston rod of the lifting cylinder I 4-9 is connected to the fixed material placing seat 4-5, which can drive the material placing seat I to lift synchronously.

[0248] In order to ensure the stability of the lifting of the material placing seat I and avoid tilting, the material placing slide I 4-2 and the material placing seat I are connected by four groups of linked guide column assemblies.

[0249] The guide column assembly includes a guide seat installed on the material placing slide I 4-2 and a guide column vertically passing through the guide seat, and adjacent guide seats are connected by a connecting rod, so as to ensure the synchronous movement of each guide column assembly, achieve the stability of the material placing seat I during lifting, and realize the stable grasping and feeding of short pipes.

[0250] The lateral movement of the material placing carriage I 4-2 is used to transfer short pipe materials from above the short pipe loading mechanism 2 to above the mesh welding mechanism 1. In order to achieve the lateral movement of the material placing carriage I 4-2, a material placing belt I 4-10 is arranged above the material placing frame 4-1, and the top of the material placing carriage I 4-2 is connected to the material placing belt I 4-10.

[0251] The material placing belt I 4-10 is horizontally arranged on the material placing frame 4-1, and the top of the material placing carriage I 4-2 is located above the material placing frame 4-1 and connected to the material placing belt I 4-10. The material placing belt I 4-10 can drive the lateral movement of the material placing carriage I 4-2.

[0252] In order to provide power for the rotation of the material placing belt I 4-10, the driving pulley of the material placing belt I 4-10 is connected with a material placing motor I 4-11.

[0253] In order to achieve the loading of long pipe materials and medium-long pipe materials, the long pipe material placing assembly includes a material placing carriage II 4-12 and a material placing seat II 4-13 which is installed below the material placing carriage II 4-12 and can be lifted and lowered. A plurality of pneumatic grippers 4-14 arranged in a row are installed at the bottom of the material placing seat II 4-13.

[0254] Among them, the material placing carriage II 4-12 can reciprocate between the conveying support 3-15 and the mesh welding mechanism 1 to achieve the loading of long pipe materials and medium-long pipe materials.

[0255] Taking the loading of long pipe materials as an example, the material placing carriage II 4-12 drives the material placing seat II 4-13 to move above the front end of the conveying track I 3-4. The material placing seat II 4-13 descends. After using the pneumatic grippers 4-14 to grab the long pipe materials, then the material placing seat II 4-13 rises, and under the action of the material placing carriage, it laterally moves to the mesh welding mechanism 1. Then the material placing seat II 4-13 descends, and the pneumatic grippers 4-14 release to place the long pipe materials on the mesh welding mechanism 1.

[0256] In order to achieve the lifting and lowering of the material placing seat II 4-13, a lifting cylinder II 4-15 is installed on the material placing carriage II 4-12, and the lower end of the piston rod of the lifting cylinder II 4-15 is connected to the material placing seat II 4-13.

[0257] In order to achieve the lateral movement of the material placing carriage II 4-12, a material placing belt II 4-16 is arranged above the material placing frame 4-1, and the material placing belt II 4-16 is connected to the material placing carriage II 4-12.

[0258] The material placing belt II 4-16 is horizontally arranged on the material placing frame 4-1, and the top of the material placing carriage II 4-12 is located above the material placing frame 4-1 and connected to the material placing belt II 4-16. It is driven to move horizontally on the material placing frame 4-1 by the material placing belt II 4-16.

[0259] To provide power for the movement of the material placing belt II 4-16, the driving pulley of the material placing belt II 4-16 is connected to a material placing motor II 4-17.

[0260] As Figure 11 - 13 shown, the mesh welding mechanism 1 is arranged in a direction parallel to the short pipe feeding mechanism 2 and perpendicular to the long pipe feeding mechanism 3, and passes through below the pipe placing mechanism 4, so as to weld a plurality of individual pipes into a mesh structure.

[0261] Among them, the mesh welding mechanism 1 includes a mesh welding machine and a welding moving assembly passing through the mesh welding machine.

[0262] Specifically, the pipe placing mechanism 4 places the pipes grabbed from the short pipe welding mechanism and the long pipe welding mechanism on the welding moving assembly, and the welding moving assembly feeds them into the mesh welding machine to weld them into a mesh.

[0263] In the mesh welding mechanism 1 of this embodiment, taking the moving direction of the pipes as the front side, that is, for the mesh welding machine, its feeding side is the rear side and the discharging side is the front side.

[0264] Specifically, the mesh welding machine includes a welding machine base 1-1. Inside the welding machine base 1-1, there is an upper electrode block 1-2 that can move up and down, and a lower electrode block 1-3 corresponding to the upper electrode block 1-2 and also capable of moving up and down.

[0265] Among them, the upper electrode block 1-2 is arranged in two rows in the front-back direction, and the front and rear upper electrode blocks 1-2 are arranged in pairs. The lower electrode block 1-3 corresponds to the upper electrode block 1-2 to form a structure of four electrode blocks in each group, that is, two upper electrode blocks 1-2 and two lower electrode blocks 1-3. Among them, two upper electrode blocks 1-2 or two lower electrode blocks 1-3 are connected to a power source to form a circuit between the four electrode blocks to realize the welding of the pipe joints.

[0266] When the pipe joint moves between the front and rear electrode blocks, the upper electrode block 1-2 and the lower electrode block 1-3 move towards each other and are energized, and the welding of the pipes can be completed.

[0267] To realize the installation and lifting of the upper electrode block 1-2, an upper electrode block mounting frame 1-4 is arranged inside the welding machine base 1-1. The upper electrode block mounting frame 1-4 is provided with two rows of upper electrode block lifting cylinders 1-5, and the upper electrode blocks 1-2 are respectively installed at the lower ends of the piston rods of the upper electrode block lifting cylinders 1-5.

[0268] The upper electrode block mounting frame 1-4 is horizontally arranged inside the welding machine base 1-1, and the two rows of upper electrode block lifting cylinders 1-5 are respectively installed on the front side and the rear side of the upper electrode block mounting frame 1-4.

[0269] To achieve the installation and lifting of the lower electrode block 1-3, a lower electrode block mounting frame 1-6 is provided inside the welding machine base 1-1. The lower electrode block 1-3 is mounted above the lower electrode block mounting frame 1-6. Two rollers 1-7 are installed at the bottom of the lower electrode block mounting frame 1-6, and the rollers 1-7 can roll on the corresponding ramp blocks 1-8.

[0270] The ramp block 1-8 moves horizontally to achieve the movement of the roller 1-7 relative to the ramp block 1-8.

[0271] When the roller 1-7 moves upward relative to the ramp block 1-8, the lower electrode block mounting frame 1-6 drives the lower electrode block 1-3 to rise. When the roller 1-7 moves downward relative to the ramp block 1-8, the lower electrode block mounting frame 1-6 drives the lower electrode block 1-3 to move downward.

[0272] To achieve the horizontal movement of the ramp block 1-8, the ramp block 1-8 is mounted on a horizontal movement slide plate 1-9. The horizontal movement slide plate 1-9 is connected to a horizontal movement cylinder 1-10 mounted on the welding machine base 1-1, and the horizontal movement cylinder 1-10 can drive the horizontal movement slide plate 1-9 to move horizontally.

[0273] The horizontal movement cylinder 1-10 is horizontally arranged on the welding machine base 1-1 and is located within the window of the horizontal movement slide plate 1-9. The piston rod of the horizontal movement cylinder 1-10 can extend and retract, driving the movement of the horizontal movement slide plate 1-9 and the ramp block 1-8 to achieve the movement of the roller 1-7 relative to the ramp block 1-8, thereby driving the lifting of the lower electrode block 1-3.

[0274] To energize the electrode block, a transformer 1-11 is provided on the welding machine base 1-1 on the discharge side of the mesh welding machine. The transformer 1-11 is connected to the corresponding electrode block through a flexible copper strip.

[0275] In this embodiment, the transformer 1-11 is connected to the lower electrode block 1-3, that is, located on the front side of the lower electrode block 1-3, to supply power to each electrode block group and complete the welding of the mesh.

[0276] To prevent the pipe from moving randomly during the welding process, a pressure roller 1-12 that can be adjusted up and down is installed on the feeding side of the mesh welding machine.

[0277] Pressure cylinders 1-13 are installed on the inner walls on both sides of the welding machine base 1-1. The two ends of the pressure roller 1-12 are installed at the lower ends of the piston rods of the pressure cylinders 1-13, and the pressure roller 1-12 can press on the pipe during welding.

[0278] To be able to supply materials to the mesh welding machine, the welding movement assembly includes a moving frame 1-14 and two welding exchange molds 1-15 installed inside the moving frame 1-14 and capable of exchanging materials for the mesh welding machine. A number of material placing blocks 1-16 are provided on the welding exchange molds 1-15.

[0279] A driving assembly 1-17 capable of driving the welding exchange die 1-15 to move is further provided on the moving frame 1-14. The two welding exchange modules can be exchanged at the rear end of the moving frame 1-14. That is, the driving assembly 1-17 can drive the welding exchange die 1-15 that has completed the pipe placement to continue moving forward for welding operations, while the vacant welding exchange die 1-15 can perform the pipe placement operation at this time. The two welding exchange dies 1-15 alternate, which can effectively improve the welding efficiency of the mesh.

[0280] The welded mesh is then moved to the front end of the moving frame 1-14 at the rear side of the mesh welding machine driven by the driving assembly 1-17, facilitating other mechanisms to move it away for subsequent processing operations.

[0281] Preferably, a liftable mesh lifting block 1-18 is installed inside the moving frame on the discharge side of the mesh welding machine for lifting the mesh to facilitate subsequent removal of the mesh from the mesh welding mechanism.

[0282] Specifically, a mesh lifting cylinder is installed at the bottom of the mesh lifting block 1-18 for controlling the lifting and lowering of the mesh lifting block 1-18.

[0283] At this time, the welding exchange die 1-15 after the mesh is removed is then moved backward to the rear end of the moving frame 1-14 driven by the driving assembly 1-17. At this time, the other welding exchange die 1-15 has completed the feeding, and the two welding exchange dies 1-15 are exchanged. The driving assembly 1-17 can then drive the other welding exchange die 1-15 to move forward for welding operations.

[0284] When the welding exchange die 1-15 passes through the mesh welding machine, the joints of each pipe can be welded to form a mesh structure.

[0285] Preferably, the driving assembly 1-17 is driven by a die conveying belt provided on the moving frame 1-14, and the die conveying belt is connected to a die conveying motor. And the driving assembly 1-17 is connected to the welding exchange die 1-15 in a hanging manner. During the exchange process of the two welding exchange dies 1-15, the two move up or down synchronously to achieve the separation of the driving assembly 1-17 from one welding exchange die 1-15 and the connection with the other welding exchange die 1-15.

[0286] The setting of the material placing block 1-16 is used for placing the pipes, ensuring the accuracy of the pipe positions and improving the welding quality of the mesh.

[0287] Such as Figure 14 - 15As shown, after the mesh sheet is welded, the mesh sheet is bent into a frame structure, and then the ends of the frame cross beams formed by the long pipes after bending are inserted into each other to ensure the overall structural strength of the frame. The insertion mechanism 5 is used for the insertion operation of the frame cross beams.

[0288] Therefore, the insertion mechanism 5 includes an insertion box 5-1 and a frame moving seat 5-2 arranged on the front side of the insertion box 5-1 and movable towards the insertion box 5-1.

[0289] In the insertion mechanism 5 of this embodiment, the position where the frame moving seat 5-2 is located is the front side, that is, the frame is placed on the frame moving seat 5-2 with the position to be inserted facing backward. The frame moving seat 5-2 moves backward, that is, moves towards the direction of the insertion box 5-1, and the structure on the insertion box 5-1 is used to perform the insertion operation on the frame.

[0290] In order to be able to insert the corresponding ends of the frame cross beams into each other, two insertion plates 5-3 that can move towards or away from each other are arranged on the insertion box 5-1. A plurality of insertion positioning blocks 5-4 corresponding to each other and arranged vertically are installed on the relative sides of the two insertion plates 5-3. An insertion pressing block 5-5 corresponding to it is installed inside the insertion positioning block 5-4, and a locking pressing block 5-6 located between the two insertion plates 5-3 is arranged between the corresponding two insertion pressing blocks 5-5.

[0291] A plurality of insertion positioning blocks 5-4 are arranged vertically at positions near the inner edge of the insertion plate 5-3, and the insertion positioning blocks 5-4 on the two insertion plates 5-3 are arranged oppositely to be used for positioning the two ends of the same frame cross beam. An insertion pressing block 5-5 is arranged inside the insertion positioning block 5-4, which is used to press the frame cross beam located inside the insertion positioning block 5-4 to ensure the stability during the insertion operation. The locking pressing block 5-6 deforms and presses the inserted part after the insertion of the frame cross beam is completed to ensure the firmness of the inserted part.

[0292] Specifically, a pressing cylinder 5-7 for controlling its pressing or loosening is arranged inside the insertion pressing block 5-5. That is, when the piston rod of the pressing cylinder 5-7 extends, the insertion pressing block 5-5 rotates downward to press on the corresponding frame cross beam, and when the piston rod of the pressing cylinder 5-7 retracts, the insertion pressing block 5-5 rotates upward to loosen the corresponding frame cross beam.

[0293] By separately setting the insertion pressing block 5-5, the individual pressing of each frame cross beam can be realized, ensuring the pressing effect of the insertion pressing block 5-5.

[0294] The locking block 5-6 is provided with a U-shaped groove. On the outer inner wall of the U-shaped groove, a fixed locking buckle is provided, and on the inner inner wall, a movable locking buckle is provided. Inside the locking block 5-6, a locking cylinder 5-8 located in the pocket box 5-1 is provided. The locking cylinder 5-8 can drive the movable locking buckle to move towards the fixed locking buckle. That is, the inserted part at the end of the frame crossbeam is placed in the U-shaped groove. When the piston rod of the locking cylinder 5-8 extends, the inserted part can be squeezed and deformed by the fixed locking buckle and the movable locking buckle, so that the inserted part is firmly connected together.

[0295] The opposite movement of the pocket plates 5-3 can drive the two ends of the same frame crossbeam to be inserted. To realize the movement of the pocket plates 5-3, a pocket cylinder 5-9 that can drive its movement is provided inside the pocket plates 5-3.

[0296] The pocket cylinder 5-9 is installed inside the pocket box 5-1, and its piston rod is connected to the inner wall of the pocket plate 5-3.

[0297] In order to detect whether the two ends of the same frame crossbeam are aligned and whether the insertion is successful, an insertion detection part 5-10 is provided on the inner wall of the pocket plate 5-3, which is used to detect whether the opposite ends of the pipe are aligned.

[0298] A detection block 5-11 is provided inside the pocket plate 5-3, and two insertion detection parts 5-10 arranged side by side and corresponding to the detection block 5-11 are provided inside the pocket box 5-1. When the two pocket plates 5-3 move towards each other to drive the frame crossbeam to be inserted, first, the detection block 5-11 will face the first insertion detection part 5-10 (the insertion detection part far from the inner edge of the pocket plate 5-3). If the first insertion detection part 5-10 can sense the detection block 5-11, it indicates that the two ends of the frame crossbeam are aligned. At this time, the two pocket plates 5-3 can continue to move towards each other until the second insertion detection part 5-10 (the insertion detection part 5-10 close to the inner edge of the pocket plate 5-3) senses the detection block 5-11.

[0299] If the first insertion detection part 5-10 does not sense the detection block 5-11, it indicates that the two ends of the frame crossbeam are misaligned, and the two pocket plates 5-3 do not need to continue to move towards each other to avoid damaging the ends of the frame crossbeam.

[0300] The insertion detection part 5-10 can be selected but is not limited to an infrared induction probe.

[0301] To realize the movement of the frame moving seat 5-2, the pocket mechanism 5 further includes a pocket base 5-12. A moving cylinder 5-13 is installed on the pocket base 5-12, and the piston rod of the moving cylinder 5-13 is connected to the frame moving seat 5-2.

[0302] The copying port box 5-1 is installed on the copying port base 5-12. The piston rod of the moving cylinder 5-13 faces the direction of the copying port box 5-1. By the extension of the piston rod, the screen frame moving seat 5-2 can be pushed to drive the screen frame to move towards the copying port box 5-1, so as to facilitate the copying port operation of the screen frame.

[0303] As Figure 16 - 18 shown, in the chassis processing equipment, first, each component is welded into a chassis semi-finished product by the chassis welding mechanism 11, and then the upper plate is manually assembled on the chassis semi-finished product to form the chassis structure. Since there are many components that make up the chassis semi-finished product, if the feeding is directly carried out on the chassis welding mechanism 11, it is not only time-consuming and laborious, but also the safety cannot be guaranteed. Therefore, a chassis feeding mechanism 6 is provided for feeding each component of the chassis semi-finished product.

[0304] Specifically, the chassis feeding mechanism 6 includes a lifting frame 6-1, a chassis conveying frame 6-2 extending into the lifting frame 6-1 from one side, a welding feeding frame 6-3 extending out from the other side of the lifting frame 6-1, and a chassis exchange mold 6-4 that can move on the chassis conveying frame 6-2 and the welding feeding frame 6-3 and can lift in the lifting frame 6-1.

[0305] The chassis semi-finished product is composed of four corner pieces, an intermediate beam, a frame, and an intermediate piece. Positioning pieces corresponding to the above-mentioned components are respectively arranged on the chassis exchange mold 6-4 to ensure the accuracy of the positions of each component.

[0306] In the chassis feeding mechanism 6 of this embodiment, the side where the chassis conveying frame 6-2 is located is the rear side, and the side where the welding feeding frame 6-3 is located is the front side, that is, each component moves forward after feeding.

[0307] An empty chassis exchange mold 6-4 can be placed on the chassis conveying frame 6-2 for feeding. The chassis exchange mold 6-4 with feeding completed can be moved to the welding feeding frame 6-3 through the chassis conveying frame 6-2, and then be sent into the chassis welding mechanism 11, and the two chassis exchange molds 6-4 can exchange positions in the lifting frame 6-1.

[0308] Specifically, the empty chassis exchange die 6-4 can be moved to the rear end of the chassis conveyor rack 6-2 for loading various components. The chassis exchange die 6-4 that has completed loading is transferred to the chassis welding mechanism 11 for welding processing. After the welding is completed and the semi-finished chassis is removed from the chassis exchange die 6-4, both chassis exchange dies 6-4 move towards the inside of the lifting frame 6-1 and exchange positions within the lifting frame 6-1. That is, the chassis exchange die 6-4 that has completed loading is sent onto the chassis welding mechanism 11, while the empty chassis exchange die 6-4 moves to the rear end of the chassis conveyor rack 6-2 for loading operations. By setting two chassis exchange dies 6-4, the loading and welding efficiency can be improved, and the operator does not need to stay at the chassis welding mechanism 11 for a long time, improving the safety of the operation.

[0309] Among them, the front end of the chassis conveyor rack 6-2 overlaps with the rear end of the welding loading rack 6-3, that is, the rear end of the welding loading rack 6-3 is located at the bottom of the front end of the chassis conveyor rack 6-2, so as to facilitate the movement of the chassis exchange die 6-4 on the chassis conveyor rack 6-2 and the welding loading rack 6-3.

[0310] By lifting one of the chassis exchange dies 6-4 to achieve the position exchange of the two chassis exchange dies 6-4. To achieve this effect, a die lifting seat 6-5 is installed inside the lifting frame 6-1, and a hanging shaft 6-6 is arranged on the inner side of the bottom of the die lifting seat 6-5. The hanging shaft 6-6 can cooperate with the hanging grooves 6-7 on both sides of the chassis exchange die 6-4.

[0311] After the semi-finished chassis on one of the chassis exchange dies 6-4 is welded and removed, the empty chassis exchange die 6-4 moves into the lifting frame 6-1.
