Description

Technical Field

[0001] The invention belongs to the field of steel structures, and in particular relates to an automatic assembly welding production line and a process method for inner partitions. Background Art

[0002] At present, in the production process of box columns in the steel structure industry, the partitions inside the box columns are all assembled and welded manually. The production technology is backward, the efficiency is low, the materials on the production site are relatively chaotic, and management is difficult.

[0003] The assembly welding work is done manually with the help of a positioning and flipping machine. The working process is as follows: according to the size of the inner partition, adjust the position of the positioning block, position the inner partition and the lining strip on the positioning block, and clamp them with a cylinder. First weld the two ends of one side, then flip 180° and weld the two ends of the other side. Finally, release the cylinder, remove the inner partition, and the assembly work is completed.

[0004] This process involves placing the inner partition horizontally, manually adjusting the position with the help of a machine, and then welding the two horizontal surfaces in steps. This process method relies more on manual operation. At the same time, larger-sized inner partitions need to be lifted to a fixed position by lifting equipment, and the welding positions of the lining strips on each horizontal surface are relatively far apart, making manual welding time-consuming and labor-intensive.

[0005] In order to improve the production efficiency of the partitions inside the box-type columns and adapt to the automation upgrade of the front-end and back-end equipment, it is urgent to design an automated assembly and welding production process and production line for the partitions inside the box-type columns. Summary of the Invention

[0006] In view of this, the present invention aims to propose an automatic assembly and welding production line and process method for inner partitions to solve the problem of low production efficiency caused by complicated production process and low degree of automation.

[0007] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0008] An automatic welding process for an inner partition, the specific method comprising:

[0009] The inner partition to be processed is set vertically and sent to the welding station so that the lining strips are welded to the sides of the inner partition at both ends. The welding guns are set on both sides of the inner partition. After the two sides of one end face of the inner partition are welded, it is turned 180 degrees and then welded to the two sides of the other end face of the inner partition.

[0010] Further, a welding supporting wheel for supporting the inner partition board is provided at the welding station. The inner partition board is gradually conveyed by the welding supporting wheel and passes through the position where the welding torch is located. The welding torch is arranged at the starting position where the inner partition board needs to be welded. After the inner partition board moves to the position corresponding to the lining strip, welding starts. Then, the welding supporting wheel drives the inner partition board and the lining strip to move together, and the welding torch gradually welds all the contact parts between the inner partition board and the lining strip.

[0011] Further, when welding the two end faces of the inner partition board, they are respectively arranged at different welding stations.

[0012] Further, the horizontally placed inner partition board is adsorbed and vertically arranged by a suction cup. Before entering the welding station, conveying guide wheels and conveying supporting wheels are provided. A guiding space for clamping the inner partition board is formed between the two conveying guide wheels. After the inner partition board is adsorbed into a vertical state, its bottom is lapped with the conveying supporting wheel, and the conveying supporting wheel provides conveying power to gradually convey the inner partition board into the welding station through the guiding space.

[0013] The welding station for the inner partition board includes a welding supporting wheel for supporting the inner partition board, a lining strip tray, and a lining strip pushing cylinder;

[0014] A lining strip tray is arranged on the side of the welding supporting wheel, and the inner partition board moves through the welding supporting wheel;

[0015] The lining strip tray realizes the actions of approaching and moving away from the inner partition board on the welding supporting wheel through a lifting and avoiding structure. A lining strip pushing cylinder is installed on the lining strip tray, and the lining strip pushing cylinder is used to push the lining strip placed on the lining strip tray and to be welded and fixed on the side of the inner partition board;

[0016] A welding torch for welding the inner partition board and the lining strip is arranged above the lining strip tray.

[0017] Further, it also includes at least one group of spot welding guide wheels. The distance between each group of spot welding guide wheels is a positioning space. The positioning space is located above the welding supporting wheel. The positioning spaces formed by multiple groups of spot welding guide wheels are on the same horizontal plane, and the inner partition board passes through the positioning space when being conveyed by the welding supporting wheel;

[0018] Each group of spot welding guide wheels includes two spot welding guide wheels arranged in a pair. The position of one spot welding guide wheel on the frame is relatively fixed, and the other spot welding guide wheel is elastically arranged on the frame, so that the distance between the two spot welding guide wheels can be changed.

[0019] Further, one end of the lining strip tray is installed with a lining strip pushing cylinder, and the other end is provided with a lining strip guide groove matching the contour of the lining strip. The lining strip on the lining strip tray passes through the lining strip guide groove and fits on the side of the inner partition board.

[0021] The strip tray realizes the movement trajectory of approaching and departing from the welding supporting wheel through the lifting and avoiding structure. A moving chute matching the movement trajectory is arranged on the frame, and the strip tray is slidably connected with the moving chute.

[0022] Further, a placing chute for accommodating strips is arranged on the strip tray.

[0023] An automatic assembly welding production line for inner partitions includes a feeding station, a first 90-degree flipping and lifting station, a first group welding station, a 180-degree flipping station, a second group welding station and a discharging station which are connected in sequence.

[0024] Conveying components are arranged at both the input end and the output end of the welding station. Through the conveying components, the inner partitions are input into or output from the welding station.

[0025] The first 90-degree flipping and lifting station adsorbs the inner partition on the feeding station and converts its posture to be perpendicular to the horizontal plane.

[0026] After the inner partition is converted to the posture perpendicular to the horizontal plane, it is lapped on the conveying component and is sent to the first group welding station by the conveying component.

[0027] Both the first group welding station and the second group welding station complete the welding of the inner partition with the strip in the vertical posture.

[0028] The 180-degree flipping station flips the inner partition therein by 180 degrees and then enters the second group welding station.

[0029] The discharging station conveys the inner partition which has completed welding in the second group welding station out of the production line.

[0030] Further, the conveying component includes a mutually cooperating conveying guide wheel set and a conveying supporting wheel. The conveying guide wheel set includes conveying guide wheels arranged in a counterpoint manner. A guiding space is formed between the two conveying guide wheels. A conveying supporting wheel is arranged below the guiding space. The conveying supporting wheel is a driving wheel and is used for carrying the inner partition and providing moving power for it.

[0031] Further, it further includes a second 90-degree flipping and lifting station which is arranged between the second group welding station and the discharging station. The second 90-degree flipping and lifting station flips the inner partition which has completed all welding into a horizontal posture, and then it is conveyed out of the production line by the discharging station.

[0032] Further, the first 90-degree flipping and lifting station includes a lifting bracket and a flipping arm. The lifting bracket is arranged in cooperation with the output end of the feeding station. A flipping arm is rotatably connected to the machine frame. A suction cup is installed at one end of the flipping arm. The suction cup can adsorb the inner partition on the lifting bracket and make the inner partition become a posture perpendicular to the horizontal plane by 90 degrees through the flipping arm.

[0033] Preferably, the lifting bracket can perform a lifting movement relative to the position where the suction cup adsorbs the inner partition.

[0034] Further, the structures of the first 90-degree flipping and lifting station and the second 90-degree flipping and lifting station are the same.

[0035] Further, the 180-degree flipping station includes a flipping base, a 180-degree flipping disc and a flipping component;

[0036] The 180-degree flipping disc is rotatably connected to the flipping base;

[0037] The flipping component includes flipping supporting wheels and flipping guiding wheels. A plurality of groups of flipping guiding wheels arranged in alignment are arranged between two flipping supporting wheels. A flipping accommodating space is formed between the plurality of groups of flipping guiding wheels;

[0038] Two groups of flipping components are arranged on the 180-degree flipping disc, and the flipping accommodating spaces of the two groups of flipping components are arranged in a crosswise manner;

[0039] The flipping supporting wheels are driving wheels, which provide moving power for the inner partition entering the flipping accommodating space, so that the inner partition can be input or output from the flipping accommodating space;

[0040] Preferably, the 180-degree flipping disc is in rolling connection with the flipping base through flipping rollers.

[0041] Compared with the prior art, the inner partition automatic welding production line and process method of the present invention have the following advantages:

[0042] (1) The inner partition automatic welding process method of the present invention changes the traditional manual welding method of horizontally placing the inner partition and performing single-sided welding. After the inner partition is vertically arranged, it is convenient for transportation and saves occupied space. The welding method of the vertically arranged inner partition is divided into welding the two sides of one end, and then welding the two sides of the other end, which can further save the problem of excessive movement of workers for welding work; at the same time, it also helps to realize the automatic welding process. The vertically arranged inner partition is convenient for the machine to automatically complete the welding, reducing the labor intensity.

[0043] (2) The structural arrangement of the welding station of the inner partition board described in the present invention can achieve the automatic feeding of the lining strip and the automatic fitting to the side of the inner partition board, further realizing the process and machine requirements of automatic welding. During the entire welding process of the inner partition board, it can be automatically moved through the setting of the spot welding guide wheel and the welding support wheel, and thus the lining strip can be welded to the inner partition board without manual intervention during this process.

[0044] (3) The arrangement of the inner partition board automatic assembly and welding production line described in the present invention can effectively meet the requirements of automatically welding the inner partition board. At the same time, the structural principle of the selected conveying component is the same as that of the conveying inner partition board in the welding station and the 180-degree flipping station, that is, it not only saves the cost brought by the same type of accessories, but also enables the inner partition board to operate stably in the entire production line, ensuring the position accuracy, improving the welding accuracy and the qualified product rate.

[0065] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0066] An automatic welding process method for the inner partition plate 11, and its specific method includes:

[0067] Vertically set the to-be-processed inner partition plate 11 and send it into the welding station, so that the lining strip 35 is welded to the two side surfaces at both ends of the inner partition plate 11. The welding torches 36 are arranged on both sides of the inner partition plate 11. After the two sides of one end face of the inner partition plate 11 are welded, it is flipped 180 degrees and then the two sides of the other end face of the inner partition plate 11 are welded.

[0068] During this period, the equipment for realizing this process method can be of existing structure or innovative equipment for further providing automation and efficiency.

[0069] And this process method can also involve automatically transporting to the position where the inner partition plate 11 is set vertically through a conveyor belt or other forms, and after the overall welding is completed, the materials can also be transported out through an automated output structure.

[0070] There is a welding supporting wheel 39 for supporting the inner partition plate 11 at the welding station. The inner partition plate 11 is transported by the welding supporting wheel 39 and gradually passes through the position where the welding torch 36 is located. The welding torch 36 is set at the starting position where the inner partition plate 11 needs to be welded. After the inner partition plate 11 moves to the position corresponding to the lining strip 35, welding starts, and then the welding supporting wheel 39 drives the inner partition plate 11 and the lining strip 35 to move together, and the welding torch 36 gradually welds all the contact parts of the inner partition plate 11 and the lining strip 35. The welding form can be various and will not be elaborated here.

[0071] When welding the two end faces of the inner partition plate 11, they are set at different welding stations, so that a high-efficiency production process can be formed.

[0072] The horizontally placed inner partition plate 11 is adsorbed and set vertically through a suction cup. Here, the suction cup can be a vacuum suction cup, an electromagnetic suction cup 22, etc. There are conveying guide wheels 25 and conveying supporting wheels 26 arranged before entering the welding station. A guiding space for clamping the inner partition plate 11 is formed between the two conveying guide wheels 25. After the inner partition plate 11 is adsorbed into a vertical state, its bottom is lapped with the conveying supporting wheel 26, and the conveying supporting wheel 26 provides conveying power to make the inner partition plate 11 gradually be transported into the welding station through the guiding space.

[0073] The welding station for the inner partition plate 11 includes a welding supporting wheel 39 for supporting the inner partition plate 11, a lining strip 35 tray 32, and a lining strip 35 pushing cylinder 31;

[0074] The lining strip 35 tray 32 is arranged on the side of the welding supporting wheel 39, and the inner partition plate 11 moves through the welding supporting wheel 39;

[0075] The strip 35 tray 32 approaches and moves away from the inner partition 11 on the welding supporting wheel 39 through a lifting and avoiding structure. A strip 35 pushing cylinder 31 is installed on the strip 35 tray 32. The strip 35 pushing cylinder 31 is used to push the strip 35 placed on the strip 35 tray 32 and to be welded and fixed to the side of the inner partition 11.

[0076] Above the strip 35 tray 32, a welding torch 36 for welding the inner partition 11 and the strip 35 is provided.

[0077] Furthermore, at least one group of spot welding guide wheels 37 is included. The distance between each group of spot welding guide wheels 37 is a positioning space. The positioning space is located above the welding supporting wheel 39. The positioning spaces formed by multiple groups of spot welding guide wheels 37 are on the same horizontal plane. When the inner partition 11 is conveyed by the welding supporting wheel 39, it passes through the positioning space.

[0078] Each group of spot welding guide wheels 37 includes two spot welding guide wheels 37 arranged in a paired manner. The position of one spot welding guide wheel 37 on the frame is relatively fixed, and the other spot welding guide wheel 37 is elastically arranged on the frame, so that the distance between the two spot welding guide wheels 37 can be changed, that is, the positioning space changes. And this structure can also be applied to the guiding space and the flipping and accommodating space. The main purpose is to better adapt to inner partitions 11 of different specifications, so that the space is sufficient to give the inner partition 11 a lateral support and position guiding effect.

[0079] One end of the strip 35 tray 32 is installed with a strip 35 pushing cylinder 31, and the other end is provided with a strip 35 guiding groove matching the contour of the strip 35. The strip 35 on the strip 35 tray 32 passes through the strip 35 guiding groove and fits against the side of the inner partition 11.

[0080] The lifting and avoiding structure includes a tray lifting cylinder 34 and a tray retracting cylinder 33 hinged to the frame. The output end of the tray lifting cylinder 34 is hinged to one end of the strip 35 tray 32 close to the inner partition 11. The output end of the tray retracting cylinder 33 is hinged to the other end of the large strip 35 tray 32, and a strip 35 pushing cylinder 31 is installed above this end.

[0081] The moving track of the strip 35 tray 32 approaching and moving away from the welding supporting wheel 39 is realized through the lifting and avoiding structure. A moving sliding groove matching the moving track is arranged on the frame, and the strip 35 tray 32 is slidably connected with the moving sliding groove.

[0082] Before the inner partition 11 enters the welding station, the pallet retraction cylinder 33 is in the retracted state, and the pallet lifting cylinder 34 is in the lowered state, ensuring there is a conveying space for the inner partition 11. The inner partition 11 is guided by the guide wheels into the welding station. After it arrives, the lifting cylinder raises, and the pallet retraction cylinder 33 advances. At this time, the double-sided lining strip 35 presses against the inner partition 11, and then the double-sided welding torch 36 starts the spot welding operation. While the inner partition 11 is being conveyed, the welding torch 36 performs spot welding until the entire lining strip 35 is welded. Subsequently, the pallet retraction cylinder 33 retracts, the pallet lifting cylinder 34 lowers, and the lining plate pushing cylinder pushes forward to press the lining strip 35, and the inner partition 11 is output from the station. Since both the pallet retraction cylinder 33 and the pallet lifting cylinder 34 are hinged connections, a four-link structure can be formed.

[0083] Further, a placement chute for accommodating the lining strip 35 is provided on the pallet 32 of the lining strip 35.

[0084] An automatic assembly welding production line for the inner partition 11 includes a feeding station 10, a first 90-degree flipping and lifting station, a first group welding station 30, a 180-degree flipping station, a second group welding station 50, and a discharging station 70 that are connected and arranged in sequence;

[0085] Conveying components are provided at both the input end and the output end of the welding station. Through the conveying components, the inner partition 11 is input or output from the welding station;

[0086] The first 90-degree flipping and lifting station adsorbs the inner partition 11 on the feeding station 10 and converts its posture to be perpendicular to the horizontal plane;

[0087] After the inner partition 11 is converted to a posture perpendicular to the horizontal plane, it is lapped on the conveying component and is sent to the first group welding station 30 by the conveying component;

[0088] Both the first group welding station 30 and the second group welding station 50 complete the welding of the inner partition 11 with the lining strip 35 in a vertical posture;

[0089] The 180-degree flipping station flips the inner partition 11 inside it by 180 degrees and then enters the second group welding station 50;

[0090] The discharging station 70 conveys the inner partition 11 that has completed welding at the second group welding station 50 out of the production line.

[0091] Further, the conveying component includes 25 groups of conveying guide wheels and conveying support wheels 26 that cooperate with each other. The 25 groups of conveying guide wheels include conveying guide wheels 25 arranged in alignment. A guiding space is formed between the two conveying guide wheels 25, and the conveying support wheel 26 is arranged below the guiding space. The conveying support wheel 26 is a driving wheel for carrying the inner partition 11 and providing moving power for it.

[0092] It further includes a second 90-degree flipping and lifting station, which is arranged between the second group of welding stations 50 and the discharging station 70. The second 90-degree flipping and lifting station flips the internally partitioned plates 11 that have been completely welded into a horizontal posture, and then they are conveyed out of the production line by the discharging station 70.

[0093] The first 90-degree flipping and lifting station includes a lifting bracket 24 and a flipping arm 21. The lifting bracket 24 is arranged in cooperation with the output end of the feeding station 10. The flipping arm 21 is rotatably connected to the machine frame. A suction cup is installed at one end of the flipping arm 21. The suction cup can adsorb the internally partitioned plates 11 on the lifting bracket 24 and make the internally partitioned plates 11 become perpendicular to the horizontal plane by 90 degrees through the flipping arm 21.

[0094] Preferably, the lifting bracket 24 can move up and down relative to the position where the suction cup adsorbs the internally partitioned plates 11.

[0095] The first 90-degree flipping and lifting station and the second 90-degree flipping and lifting station have the same structure.

[0096] Furthermore, the 180-degree flipping station includes a flipping base 41, a 180-degree flipping disk, and a flipping component.

[0097] The 180-degree flipping disk is rotatably connected to the flipping base 41.

[0098] The flipping component includes flipping supporting wheels 42 and flipping guiding wheels 45. Multiple groups of flipping guiding wheels 45 arranged in alignment are provided between the two flipping supporting wheels 42. A flipping accommodation space is formed between the multiple groups of flipping guiding wheels 45.

[0099] Two groups of flipping components are arranged on the 180-degree flipping disk, and the flipping accommodation spaces of the two groups of flipping components are arranged in a cross shape.

[0100] The flipping supporting wheels 42 are driving wheels, which provide moving power for the internally partitioned plates 11 entering the flipping accommodation space, so that the internally partitioned plates 11 can be input into or output from the flipping accommodation space.

[0101] Preferably, the 180-degree flipping disk is in rolling connection with the flipping base 41 through flipping rollers 43.

[0102] The working principle is as follows. The welding station used during this period can be the structure proposed above.

[0103] The internally partitioned plates 11 are conveyed to the first 90-degree flipping and lifting station by the feeding station 10. Multiple internally partitioned plates 11 can be accommodated on the lifting bracket 24 of the first 90-degree flipping and lifting station, and the lifting bracket 24 can rise so that the suction cup can adsorb the uppermost internally partitioned plates 11.

[0104] The flipping arm 21 realizes a 90-degree flip through the flipping shaft 23, enabling the suction cup on it to adsorb the inner partition 11 and change the posture of the inner partition 11 to be perpendicular to the horizontal plane (the horizontal plane here is a relative position, as long as it is perpendicular to the welding station).

[0105] Then, the conveying idler wheel 26 in the conveying component provides a conveying power for the inner partition 11 lapped on it by rotating, and the conveying guide wheel 25 gives a guiding effect.

[0106] It is sent into the first group of welding stations 30 by the conveying component, and the two sides at one end of the inner partition 11 are welded to the corresponding lining strips 35 respectively.

[0107] The lining strip 35 pushing cylinder 31 continuously pushes the lining strip 35 on the lining strip 35 tray 32 to a position close to the side of the inner partition 11, so that the lining strip 35 can keep close to the inner partition 11. After welding is completed, the lining strip 35 tray 32 is moved away from the welding idler wheel 39 or the inner partition 11 through the lifting and avoiding component, giving way for the input of a new inner partition 11.

[0108] The inner partition 11 is conveyed to the initial welding position of the lining strip 35, and then the welding gun 36 starts welding. After welding this position, the welding idler wheel 39 will further drive the inner partition 11 to move. At this time, the lining strip 35 that has formed welding points with the inner partition 11 will move along. During the continuous movement, the welding gun 36 will continuously weld other positions where the inner partition 11 contacts the lining strip 35 until all welding is completed, and then the inner partition 11 will leave the welding station and enter another station.

[0109] The inner partition 11 is clamped into the flipping accommodation space by the flipping idler wheel 42 and the flipping guide wheel 45, and then is driven to flip 180 degrees. After that, it is output from the 180-degree flipping station as the flipping idler wheel 42 continues to rotate.

[0110] Then it enters the second group of welding stations 50 and continues the welding process of the first group of welding stations 30.

[0111] The inner partition 11 after welding in the second group of welding stations 50 is in the state of being completely welded. Through the second 90-degree flipping and lifting station, the vertical state of the inner partition 11 is changed back to the horizontal state and is conveyed by the discharging station 70. Here, the discharging station 70 can have the same structure as the feeding station 10.

[0112] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
