Description

Technical Field

[0001] The present application relates to an assembly production line for truss floor slabs, belonging to the technical field of truss floor slab processing. Background Art

[0002] Truss floor slabs are formed by assembling, punching, and wire drilling trusses and plates. Multiple truss floor slabs can be spliced and combined at the construction site, and then concrete is cast for construction, which speeds up the construction progress, thereby shortening the construction period and achieving the purpose of cost savings.

[0003] Currently, in the assembly of trusses and plates, one method is to stack the trusses on a truss placement plate, then use a manipulator to place the substrate on the truss, and finally use the manipulator to transport the truss and the substrate together to the next operation station; another method is to fix the truss on a truss clamping mechanism, push the plate above the truss through a pushing plate mechanism to place the plate, and then the truss clamping mechanism transports the truss and the plate together to the next operation station. In the existing assembly production line of trusses and plates, the assembly positions of the trusses and plates depend on the initial placement positions of the trusses and plates, and it is impossible to adjust the positions of the trusses and plates, resulting in deviations in the positioning of the plates and trusses, causing the plates and trusses to be unable to be assembled according to the original plan, affecting subsequent punching and wire drilling processes, and reducing the connection strength and connection stability between the trusses and plates.

This production line can improve the positioning accuracy of the plates and trusses, ensure that the plates and trusses are assembled according to the original plan, facilitate the smooth progress of subsequent punching and wire drilling processes, and improve the connection strength and connection stability between the trusses and plates.

[0073] Reference Figure 1-16, embodiments of the present application disclose an assembly production line for truss floor slabs, including: a frame 100; a truss placement rack 800, the truss placement rack 800 is arranged below the frame 100, and at least two rows of support components are arranged on the truss placement rack 800, and the support components are used to support the truss; a support frame 400, the support frame 400 is arranged on one side of the sheet placement rack 300, a truss limiting frame 500 is installed on the support frame 400, the truss limiting frame 500 can move horizontally along the support frame 400, at least two rows of truss limiting components and at least one row of sheet lifting seats 520 are arranged on the truss limiting frame 500, the truss limiting components are used to fix the truss, the sheet lifting seats 520 can rise or fall, and the sheet lifting seats 520 are used to lift the sheet; a truss transfer rack 220, the truss transfer rack 220 is connected to the frame 100, the truss transfer rack 220 can move horizontally along the frame 100 and can rise or fall relative to the frame 100, at least two rows of truss chucks are arranged below the truss transfer rack 220, and the truss chucks are used to clamp the truss; a sheet placement rack 300, the sheet placement rack 300 is arranged on the side of the support frame 400 away from the truss placement rack 800, a fixed plate 310, a first positioning plate 330, a movable plate 320 and a second positioning plate 340 are respectively arranged around the sheet placement rack 300, the movable plate 320 can approach or move away from the fixed plate 310, and the first positioning plate 330 and the second positioning plate 340 can move towards or away from each other; a sheet transfer rack 200, the sheet transfer rack 200 is connected to the frame 100, the sheet transfer rack 200 can move horizontally along the frame 100 and can rise or fall relative to the frame 100, at least two suction cups 201 are arranged at the bottom of the sheet transfer rack 200, and the suction cups 201 are used to grab the sheet; a sheet positioning component, the sheet positioning component is used to adjust the position of the sheet on the truss limiting frame 500; a pressing component, the pressing component is used to press the sheet on the truss limiting frame 500.

[0074] In this production line, the truss is initially positioned in the truss placement rack 800 and transported to the truss limiting rack 500 by the truss transfer rack 220 for fixed clamping. After the truss is fixed, the sheet transfer rack 200 grabs the sheet placed on one side of the sheet placement rack 300 through the suction cup 201, then moves horizontally along the machine frame 100, and adjusts the vertical height of the suction cup 201 by rising or falling, so as to place the sheet on the sheet placement rack 300; the fixed plate 310 on the sheet placement rack 300 remains stationary, and the movable plate 320 moves closer to the fixed plate 310, then the fixed plate 310 and the movable plate 320 respectively abut against the two opposite side surfaces of the sheet to complete the positioning in the length direction of the sheet. The first positioning plate 330 and the second positioning plate 340 move towards each other, then the first positioning plate 330 and the second positioning plate 340 respectively abut against the other two opposite side surfaces of the sheet to complete the positioning in the width direction of the sheet; the sheet transfer rack 200 transports the sheet that has been initially positioned by the sheet placement rack 300 above the truss on the truss limiting rack 500. The sheet lifting seat 520 rises to first lift the sheet, and then the sheet positioning assembly can adjust the position of the sheet placed above the truss again. After adjustment, the sheet lifting seat 520 descends, and the sheet abuts completely against the truss, and the pressing assembly is used to realize the pressing and fixing of the sheet and the truss. Then, the system transports the truss and the sheet together to the next punching, drilling and locking mechanism 900 along the horizontal movement of the truss limiting rack 500 along the support frame 400 for punching and wire drilling processing.

[0075] This production line initially positions the truss and the sheet through the truss placement rack 800 and the sheet placement rack 300 respectively, and then re - positions through the truss limiting rack 500 and the sheet positioning assembly to improve the positioning accuracy and assembly precision of the sheet and the truss. Then, the pressing assembly is used to realize the pressing and fixing of the sheet and the truss, ensuring that the truss and the sheet are always tightly assembled in the next processing step, facilitating the smooth progress of the subsequent punching and wire drilling processes, improving both the connection strength and connection stability between the truss and the sheet, and also improving the processing efficiency of the truss and the sheet, which is convenient for mass - producing this truss floor slab.

[0076] The truss transfer rack 220 contains at least two rows of truss chucks. Cooperating with the truss placement rack 800, it can hoist multiple neatly arranged trusses onto the truss limiting rack 500 at one time, improving the transfer efficiency of the truss and the positioning accuracy of the truss on the truss limiting rack 500, and further improving the assembly degree and assembly efficiency of the truss and the base plate. The machine frame 100 provides support force and movement path for the truss transfer rack 220 and the sheet transfer rack 200, thus improving the stability of the truss transfer rack 220 and the sheet transfer rack 200 during the horizontal movement along the machine frame 100, and realizing the rapid transfer of the truss and the sheet.

[0077] As an implementation manner, the lifting or lowering of the sheet material lifting seat 520 is realized by a cylinder, which can improve the lifting stability and efficiency of the sheet material.

[0078] Specifically, the sheet material lifting seat 520 can be directly arranged on the truss limiting frame 500, or fixed on one side of the limiting seat 511, as long as it does not affect the functions of the truss limiting seat 511 and the limiting block 512 on the truss.

[0079] More specifically, the number of columns of the truss limiting component and the sheet material lifting seat 520 is not limited, and those skilled in the art can set it according to the actual width of the sheet material, and it is only necessary to ensure that there are enough trusses for assembling with the sheet material and the sheet material lifting seat 520 can stably lift the sheet material.

[0080] As an implementation manner, the support component includes a support pile 810 and a support member 821. The bottom of the support pile 810 is connected to the truss placement frame 800, and the top is connected to the support member 821. A limiting plate 822 is arranged on the support member 821, and the upper end surfaces of adjacent support members 821 and the limiting plate 822 form a placement space for placing the truss.

[0081] The support pile 810 provides a support force for the support member 821. Since the truss is generally triangular, when the support members 821 on adjacent support piles 810 are used to support one truss, the truss is placed in an inverted triangle, and the distance between adjacent support piles 810 is used to accommodate the truss. The limiting plate 822 on the support member 821 abuts against the side surface of the truss to limit the left - right movement of the truss. The support member 821 and the limiting plate 822 can lift and fix the truss, and are convenient for the truss clamp to clamp the truss.

[0082] As an implementation manner, two support members 821 are connected to the support pile 810, and the support members 821 on adjacent support piles 810 correspond to each other in pairs. This setting can, on the one hand, save the number of support piles 810, and on the other hand, save the placement space of the trusses, and can increase the placement quantity of the trusses in a limited space. Those skilled in the art can understand that this setting can increase the number of trusses required on the same sheet material. When a certain sheet material does not need to be provided with many trusses, the trusses can be placed at intervals between multiple columns of support members 821 to improve the operation flexibility of the production line.

[0083] Those skilled in the art can understand that the support member 821 is connected to the top of the support pile 810, and the upper end surface of the support member 821 mainly plays a supporting role for the truss. When the upper end surface of the support member 821 is flush with the upper end surface of the support pile 810, the support pile 810 can also play a supporting role for the truss. In this setting, the support pile 810 can share part of the weight of the truss, and increase the contact area with the truss, which can avoid damage to the support member 821 and extend the service life of the support component.

[0084] As an implementation manner, the side of the limiting plate 822 close to the truss is inclined downward, and the width of the top of the limiting plate 822 is smaller than that of the top. Refer to Figure 9 , since two support members 821 are connected to one support pile 810, and the support members 821 cooperate with the support members 821 on the adjacent support piles 810 to accommodate one truss. The inclined setting of the limiting plate 822 enables the placement space of the truss to gradually become smaller from the top of the limiting plate 822 downward. First, it is convenient for the truss to be placed on the support member 821. Second, after the truss contacts the support member 821, the bottom of the limiting plate 822 abuts against the truss, improving the limiting effect on the truss and preventing the truss from sliding on the support member 821.

[0085] In actual production, sometimes it is necessary to adjust the size of the truss according to the size of the truss floor slab, and the size of the truss also changes. The existing support components cannot be adjusted according to the change of the truss size. Therefore, when replacing trusses of different sizes for production, only the support components can be replaced in batches, and this replacement process takes a long time.

[0086] As an implementation manner of the present application, threaded holes are provided on the support pile 810, and horizontal strip-shaped openings are provided on the support member 821. The threaded holes and the strip-shaped openings are connected by bolts. The length of the strip-shaped opening is relatively long, so the position of the support member 821 on the support pile 810 can be adjusted, and further the width of the truss placement space can be adjusted. Without replacing the support components, it can adapt to trusses of different sizes, improving the universality and practicability of the truss placement rack 800.

[0087] As an implementation manner, the truss limiting component includes a limiting seat 511 and a limiting block 512 installed above the limiting seat 511. The limiting seat 511 is used to support the truss, and the limiting blocks 512 on adjacent limiting seats 511 are used to fix one truss. Adjusting holes are provided on the limiting block 512, the adjusting holes are strip-shaped, and fixing holes are provided on the limiting seat 511. The adjusting holes and the fixing holes are connected by bolts. Refer to Figure 15-16 , the top surface of the limiting seat 511 supports the truss, and the limiting block 512 contacts the side surface of the truss to realize the clamping and fixing of the truss, improving the positioning stability of the truss. Since the length of the adjusting hole is relatively long, the position of the limiting block 512 on the limiting seat 511 can be adjusted, and further the width of the truss placement space can be adjusted. Without replacing the support components, it can adapt to trusses of different sizes, improving the universality and practicability of the truss limiting rack 500.

[0088] Under this setting, only one limiting block 512 can be provided on one limiting seat 511, and the limiting blocks 512 on adjacent limiting seats 511 form a placing space to realize the clamping and fixing of a truss. Two limiting blocks 512 can also be provided on one limiting seat 511, and the adjacent limiting blocks 512 on adjacent limiting seats 511 form a placing space to complete the clamping and fixing of a truss, which can increase the number of trusses placed, save the number of parts of the truss limiting component, and improve the structural compactness of the truss limiting component.

[0089] As an implementation manner, the truss chuck includes a fixing plate 221, a first clamping plate 224 and a second clamping plate 225 respectively arranged on both sides of the fixing plate 221. The fixing plate 221 is connected to the truss transfer rack 220. The first clamping plate 224 and the second clamping plate 225 can move towards or away from each other. A first notch 228 is provided on the side of the first clamping plate 224 close to the second clamping plate 225, and a second notch 229 is provided on the side of the second clamping plate 225 close to the first clamping plate 224. The first notch 228 and the second notch 229 are used for clamping the truss.

[0090] The first clamping plate 224 and the second clamping plate 225 move towards each other, so as to realize the clamping of the truss through the first notch 228 and the second notch 229. The first clamping plate 224 and the second clamping plate 225 move away from each other, so as to release the clamping of the truss. The truss can be placed on the truss limiting rack 500, which improves the clamping efficiency and flexibility of the truss.

[0091] Since the first clamping plate 224 and the second clamping plate 225 are in direct contact with the truss, deformation or damage will inevitably occur during long-term use. If continued to be used, the clamping force of the truss chuck on the truss will be unstable, and the dislocation or dropping of the truss is likely to occur.

[0092] As an implementation manner, the truss chuck further includes a first connecting plate 222 and a second connecting plate 223. The top end of the first connecting plate 222 is connected to one side of the fixing plate 221 through a first air cylinder 226, and the bottom end is connected to the first clamping plate 224. The top end of the second connecting plate 223 is connected to the side of the fixing plate 221 away from the first connecting plate 222 through a second air cylinder 227, and the bottom end is connected to the second clamping plate 225.

[0093] Under this setting, the first connecting plate 222 and the second connecting plate 223 are respectively connected to the fixed plate 221 through the first cylinder 226 and the second cylinder 227. The first cylinder 226 and the second cylinder 227 drive the first connecting plate 222 and the second connecting plate 223 to move towards or away from each other, thereby driving the first clamping plate 224 and the second clamping plate 225 to move towards or away from each other, realizing the clamping and putting down of the truss. The setting of the first connecting plate 222 and the second connecting plate 223 can not only improve the stability of the movement of the first clamping plate 224 and the second clamping plate 225, but also enable the timely replacement of the first clamping plate 224 and the second clamping plate 225 when the first clamping plate 224 and the second clamping plate 225 are damaged or deformed, improving the maintenance convenience of the truss chuck, extending the service life of the truss chuck, and saving the replacement cost of parts.

[0094] Specifically, the first clamping plate 224 and the first connecting plate 222 are connected by bolts, and the second clamping plate 225 and the second connecting plate 223 are also connected by bolts. This bolt connection method can facilitate the disassembly and installation of the first clamping plate 224 and the second clamping plate 225, and improve the replacement efficiency of parts.

[0095] As an implementation manner, it further includes a third cylinder 331 and a fourth cylinder 341. One end of the third cylinder 331 is connected to the side surface of the second side of the plate placing rack 300, and the other end is connected to the first positioning plate 330. One end of the fourth cylinder 341 is connected to the side surface of the fourth side of the plate placing rack 300, and the other end is connected to the second positioning plate 340.

[0096] By driving the first positioning plate 330 to move through the third cylinder 331 and driving the second positioning plate 340 to move through the fourth cylinder 341, the first positioning plate 330 and the second positioning plate 340 move towards or away from each other, thereby completing the positioning of the width direction of the plate, and improving the operation convenience of the first positioning plate 330 and the second positioning plate 340.

[0097] As an implementation manner, there are at least two third cylinders 331, which are evenly distributed along the side surface of the second side; there are at least two fourth cylinders 341, which are evenly distributed along the side surface of the fourth side. Under this setting, it can not only improve the positioning efficiency of the first positioning plate 330 and the second positioning plate 340, but also ensure that the first positioning plate 330 and the second positioning plate 340 remain parallel during the movement towards or away from each other, further improving the positioning accuracy of the plate.

[0098] As an implementation manner, the fixed plate 310 is fixed on the first side of the plate placing rack 300. A first rack 321 is arranged on the plate placing rack 300 and extends from the third side to the first side of the plate placing rack 300. The movable plate 320 is connected to the first rotating motor 322, and a first gear meshing with the first rack 321 is arranged at the output end of the first rotating motor 322. The first rack 321 is fixed. By rotating the first rotating motor 322 to drive the first gear to rotate, the first gear moves along the first rack 321, driving the movable plate 320 to approach or move away from the fixed plate 310. This setting improves the stability of the movable plate 320 during movement, thus ensuring that the fixed plate 310 and the movable plate 320 are always arranged in parallel, and further improving the positioning accuracy of the plate placing rack 300 for the plate.

[0099] As an implementation manner, a first slide rail 323 is further arranged on the plate placing rack 300 and extends from the third side to the first side of the plate placing rack 300. A first clamping groove 324 cooperating with the first slide rail 323 is arranged on the bottom surface of the movable plate 320. The cooperation of the first slide rail 323 and the first clamping groove 324 can increase the contact area between the movable plate 320 and the plate placing rack 300, further improving the stability of the movable plate 320 during movement and improving the safety and reliability of the mechanism during positioning.

[0100] As a preferred implementation manner, there are two first slide rails 323 and two first clamping grooves 324, which can further improve the stability of the movable plate 320 during movement and ensure that the movable plate 320 and the fixed plate 310 are always in a parallel state.

[0101] Those skilled in the art can understand that the settings of the first rack 321 and the first slide rail 323 will not affect the flatness of the plate on the plate placing rack 300. That is, when the two sides of the plate placing rack 300 are in contact with the bottom surface of the plate to complete the lifting of the plate, brackets with a relatively low vertical height can be arranged on the plate placing rack 300, and the first rack 321 and the first slide rail 323 can be arranged on the brackets.

[0102] As an implementation manner, the plate positioning assembly includes a first plate limiting plate 610, a first moving plate 620, a support plate 630, a second plate limiting plate 640, and a second moving plate 650. The pressing assembly is used to press the plate against the support plate 630 and the second plate limiting plate 640. The first plate limiting plate 610 is installed on the first side of the truss limiting frame 500. The first moving plate 620 is arranged opposite to the first plate limiting plate 610. The first moving plate 620 can rise or fall relative to the truss limiting frame 500, and a rolling bearing 623 is arranged below the first moving plate 620. The rolling bearing 623 can be in contact with the plate. The support plate 630 is arranged on the fourth side of the truss limiting frame 500. The support plate 630 is used to support the plate. The second plate limiting plate 640 is installed on the second side of the truss limiting frame 500. The second plate limiting plate 640 can support the plate. The second moving plate 650 is arranged above the support plate 630. The second moving plate 650 can approach or move away from the second plate limiting plate 640.

[0103] After the plate lifting seat 520 lifts the plate, then the first plate limiting plate 610, the first moving plate 620, the second plate limiting plate 640, and the second moving plate 650 are respectively in contact with the four sides of the plate, so that the position of the plate can be adjusted again to improve the accuracy of the plate position. Subsequently, the plate lifting seat 520 descends, and the plate is in contact with the truss. And the bottom of the second side and the fourth side of the plate are supported by the support plate 630 and the second plate limiting plate 640, which can improve the accuracy of the assembly of the plate and the truss. Finally, the plate is pressed against the support plate 630 and the second plate limiting plate 640 by the pressing assembly, and the rolling bearing 623 rises to be in contact with the top surface of the plate, so as to realize the pressing and fixing of the plate and the truss. When the first moving plate 620 adjusts the position of the plate, along with the horizontal movement of the truss limiting frame 500 along the support frame 400, the rolling bearing 623 first contacts the side surface of the plate to realize the repositioning of the plate. After the pressing assembly presses and fixes, the first moving plate 620 rises. Then the truss limiting frame 500 continues to move horizontally along the support frame 400, and the rolling bearing 623 contacts the top surface of the plate, and the center of the plate is pressed through the roller bearing, so as to improve the contact tightness between the plate and the truss, thereby facilitating subsequent punching and wire drilling operations and improving the connection strength and connection stability between the truss and the plate.

[0104] In the above process of re-adjusting the position of the plate, the plate lifting seat 520 lifts the plate and then adjusts the position of the plate, which can make the plate disengage from the truss during the adjustment process, avoid the movement of the plate and cause the truss to be misaligned, and further improve the assembly accuracy of the production line. The first plate limiting plate 610, the first moving plate 620, the second plate limiting plate 640 and the second moving plate 650 are respectively abutted against the four sides of the plate to achieve the position adjustment of the plate. The first plate limiting plate 610 is fixed, and as the truss limiting frame 500 moves, the plate gradually contacts the rolling bearing 623, which can achieve the limiting and fixing of plates of different widths; the second plate limiting plate 640 is fixed, and the second moving plate 650 is close to or away from the second plate limiting plate 640, which can achieve the limiting and fixing of plates of different lengths. The setting of the above parts can ensure that the plate positioning assembly can limit plates of different sizes, thereby completing the assembly with the truss, thereby improving the practicality and universality of the plate positioning assembly, and can be used for the production and processing of truss floor plates with different size requirements.

[0105] As an embodiment, it also includes a fixed frame 410, the bottom of the fixed frame 410 is connected to the support frame 400, a telescopic rod 411 is arranged on the top of the fixed frame 410, the telescopic rod 411 is connected to the first movable plate 620, a through hole 621 is arranged on the first movable plate 620, a threaded rod 622 is connected above the rolling bearing 623, the threaded rod 622 passes through the through hole 621, and is connected to the first movable plate 620 by bolts.

[0106] The fixed frame 410 provides a support point for the first movable plate 620, and the telescopic rod 411 drives the first movable plate 620 to rise or fall, so as to realize the positioning of the plate and the real-time compression during processing, reduce the gap between the plate and the truss, and improve the operational stability of subsequent punching and drilling. The design of the threaded rod 622 and the through hole 621 can be adjusted according to different plate thicknesses, so that the position adjustment and compression and fixation of plates of different thicknesses can be completed without adjusting the telescopic program of the telescopic rod 411; secondly, because the rolling bearing 623 is pressed against the plate, the threaded rod 622 and the rolling bearing 623 are also subjected to the force, and this setting can facilitate the timely replacement of the rolling bearing 623 and improve the replacement efficiency of parts.

[0107] The extension and retraction of the telescopic rod 411 are driven by a cylinder, and in order to improve the stability of the first movable plate 620 during ascent or descent, a sliding rail is provided on the fixed frame 410, and the first movable plate 620 is provided with a sliding groove that cooperates with the sliding rail. As the first movable plate 620 rises or falls, the sliding rail and the sliding groove slide against each other but do not lose contact, thereby improving the stability of the first movable plate 620.

[0108] As an implementation manner, the rolling bearing 623 is arranged in a single row. There are at least four rolling bearings 623, which are evenly distributed under the first moving plate 620. This setting can disperse the acting force on the rolling bearing 623, extend the service life of the rolling bearing 623, and secondly, can improve the pressing effect on the plate and the flatness of the plate after pressing, and reduce the stress between the plate and the truss after punching and wire drilling.

[0109] As an implementation manner, the pressing assembly includes a rotary cylinder 710, a connecting rod 720, and a pressing block 730. The rotary cylinder 710 is fixed on the truss limiting frame 500. One end of the connecting rod 720 is connected to the top of the rotary cylinder 710, and the other end of the connecting rod 720 is connected to the top of the pressing block 730.

[0110] The rotary cylinder 710 is fixed on the truss limiting frame 500. Under gas pressure, the rotary cylinder 710 rotates, driving the connecting rod 720 and the pressing block 730 to rotate, so as to press the plate with adjusted position on the support plate 630 and the second plate limiting plate 640, and complete the pressing and fixing of the plate and the truss. Refer to Figure 15-16 , when the punching process of the plate and the truss is completed, the gas pressure of the rotary cylinder 710 can be adjusted to adjust the pressing block 730 to the initial position, which is convenient for pressing the next plate. The settings of the rotary cylinder 710, the connecting rod 720, and the pressing block 730 can not only improve the pressing efficiency of the plate, but also improve the assembly accuracy of the plate and the truss, thus facilitating the subsequent production and processing of the truss floor slab and improving the quality of the truss floor slab.

[0111] As an implementation manner, the second moving plate 650 is connected to the truss limiting frame 500 through a fifth cylinder 651. The fifth cylinder 651 is used to push the second moving plate 650 to approach or move away from the second plate limiting plate 640. The fifth cylinder 651 is used to realize the approach or separation of the second moving plate 650 from the second plate limiting plate 640, improving the moving efficiency of the second moving plate 650. The pushing distance of the fifth cylinder 651 on the second moving plate 650 can be set according to the actual width requirement of the plate.

[0112] As an implementation manner, the second moving plate 650 is in the shape of a long strip plate, and the second moving plate 650 is arranged on the truss limiting frame 500 along its length direction. An activity hole 652 is formed in the second moving plate 650. The opening distance of the activity hole 652 along the width direction of the second moving plate 650 is greater than the diameter of the rotating cylinder 710. The activity hole 652 is used to accommodate the rotating cylinder 710. Under this setting, the second moving plate 650 is in the shape of a long strip plate, which can increase the contact area between the second moving plate 650 and the fourth side of the plate, thereby improving the adjustment efficiency of the plate and the positioning accuracy of the plate. Since the second moving plate 650 can be close to or away from the second plate limiting plate 640, when the rotating cylinder 710 is arranged in the activity hole 652, the rotating cylinder 710 is fixed. Therefore, the opening distance of the activity hole 652 along the width direction of the second moving plate 650 being greater than the diameter of the rotating cylinder 710 can ensure the smooth movement of the second moving plate 650. Under the condition that other conditions are the same, the longer the connecting rod 720 is, the larger the rotation radius of the pressing block 730 is, and thus the smaller the pressing force on the plate is. Forming the activity hole 652 in the second moving plate 650 can reduce the length of the connecting rod 720. First, it can ensure the pressing force of the pressing block 730 on the plate and improve the assembly accuracy between the truss and the plate. Second, it can reduce the placement space of components and improve the structural compactness of the plate positioning assembly. Third, the cooperation between the activity hole 652 and the rotating cylinder 710 can play a role in limiting the second moving plate 650, improve the horizontal consistency of the side surface of the second moving plate 650 in contact with the plate, and further improve the position accuracy of the plate.

[0113] As an implementation manner, a second rack is arranged on the support frame 400, and a second rotating motor is arranged at the bottom of the truss limiting frame 500. The output end of the second rotating motor is connected with a rotating gear, and the rotating gear meshes with the second rack. Under this setting, the second rack is fixed. When the second rotating motor rotates under the energized state, it drives the rotating gear to rotate. The rotating gear meshes with the second rack, so that the rotating gear moves along the second rack, and further drives the second rotating motor and the truss limiting frame 500 to move, so that the truss limiting frame 500 transports the assembled truss and plate to the next processing position.

[0114] As an implementation manner, a second slide rail is arranged at the top of the support frame 400, and a second card slot is arranged at the bottom of the truss limiting frame 500. The second rack is arranged on one side of the support frame 400. Under this setting, the stability of the truss limiting frame 500 moving horizontally along the support frame 400 can be improved, and it does not prevent the engagement between the second rack and the rotating gear. The second rack can be arranged upward or downward, as long as it is stably fixed on the support frame 400 to provide a movement path for the rotating gear.

[0115] As an implementation manner, a first cross beam 110 and a second cross beam 140 are arranged on a frame 100. The first cross beam 110 can move horizontally along the frame 100. A sheet material transfer rack 200 is connected to the first cross beam 110 through a first transfer moving rack 210. The first transfer moving rack 210 drives the sheet material transfer rack 200 to rise or fall relative to the first cross beam 110. The second cross beam 140 can move horizontally along the frame 100. A truss transfer rack 220 is connected to the second cross beam 140 through a second transfer moving rack 230. The second transfer moving rack 230 drives the truss transfer rack 220 to rise or fall relative to the second cross beam 140.

[0116] The first cross beam 110 and the first transfer moving rack 210, as the connection medium between the sheet material transfer rack 200 and the frame 100, improve the stability of the sheet material transfer rack 200 during horizontal movement and rising or falling. The frame 100 provides a supporting force and a moving path for the first cross beam 110 and the sheet material transfer rack 200. When the first cross beam 110 moves horizontally along the frame 100, it drives the sheet material transfer rack 200 to move horizontally along the frame 100, so as to ensure the stability of the sheet material transfer rack 200 during horizontal movement, and further improve the stability and safety of the sheet material during transfer, and realize the rapid transfer of the sheet material. Similarly, the second cross beam 140 and the second transfer moving rack 230 can improve the stability and safety of the truss during transfer, and realize the rapid transfer of the truss.

[0117] As an implementation manner, a horizontal rack 120 is arranged on the frame 100. A third rotating motor 111 is arranged on the first cross beam 110. A third gear meshing with the horizontal rack 120 is arranged at the output end of the third rotating motor 111. When the third rotating motor 111 rotates, it is used to drive the first cross beam 110 to move horizontally along the frame 100. A fourth rotating motor 141 is arranged on the second cross beam 140. A fourth gear meshing with the horizontal rack 120 is arranged at the output end of the fourth rotating motor 141. When the fourth rotating motor 141 rotates, it is used to drive the first cross beam 110 to move horizontally along the frame 100. The arrangement of the same horizontal rack 120 can provide a path for the movement of the first cross beam 110 and the second cross beam 140, saving the processing cost of the frame 100. The horizontal movement of the sheet material and the truss is respectively realized through the third rotating motor 111 and the fourth rotating motor 141, further improving the stability of the sheet material and the truss during horizontal movement.

[0118] As an implementation manner, a first vertical rack 211 is provided on the first transfer mobile rack 210, a fifth rotating motor 112 is provided on the first cross beam 110, a fifth gear meshing with the first vertical rack 211 is provided at the output end of the fifth rotating motor 112, and the fifth rotating motor 112 rotates to drive the sheet transfer rack 200 to rise or fall; a second vertical rack 231 is provided on the second transfer mobile rack 230, a sixth rotating motor 142 is provided on the second cross beam 140, a sixth gear meshing with the second vertical rack 231 is provided at the output end of the sixth rotating motor 142, and the sixth rotating motor 142 rotates to drive the truss transfer rack 220 to rise or fall.

[0119] The above settings improve the stability of the sheet transfer rack 200 and the truss transfer rack 220 during lifting and moving, and there is no interference with their horizontal movement. The sheet transfer rack 200 and the truss transfer rack 220 can be lifted and horizontally moved simultaneously, improving the transfer efficiency of the sheet transfer rack 200 and the truss transfer rack 220.

[0120] As a preferred implementation manner, there are two first transfer mobile racks 210, and both of the two first transfer mobile racks 210 are installed on the same first cross beam 110. There are two second transfer mobile racks 230, and both of the two second transfer mobile racks 230 are installed on the same second cross beam 140. The horizontal racks 120, the third rotating motor 111, and the fourth rotating motor 141 on the frame 100 are also two respectively, which can ensure the synchronism of the two first transfer mobile racks 210 and the two second transfer mobile racks 230 during horizontal movement, and further improve the stability of the sheet transfer rack 200 and the truss transfer rack 220 during horizontal movement.

[0121] As a preferred implementation manner, there is one fifth rotating motor 112 and one sixth rotating motor 142. The fifth rotating motor 112 drives the first rotating shaft to rotate, and both ends of the first rotating shaft are respectively meshed with the first vertical rack 211 of a first transfer mobile rack 210. The sixth rotating motor 142 drives the second rotating shaft to rotate, and both ends of the second rotating shaft are respectively meshed with the second vertical rack 231 of a second transfer mobile rack 230. This setting can increase the power for the sheet transfer rack 200 and the truss transfer rack 220 during rising or falling, improve the lifting efficiency, and respectively ensure the horizontal synchronism of the sheet transfer rack 200 and the truss transfer rack 220 during the rising or falling process, so as to ensure that the suction cups 201 and the truss chucks are always in a horizontal state, and further improve the stability of the sheet transfer rack 200 and the truss transfer rack 220 during movement.

[0122] As an implementation manner, a horizontal slide rail 130 is arranged on the rack 100, a first vertical slide rail 212 is arranged on the first transfer moving frame 210, a first horizontal slot matching with the horizontal slide rail 130 is arranged at the bottom of the first cross beam 110, and a first vertical slot matching with the first vertical slide rail 212 is arranged on the side surface of the first cross beam 110 in contact with the first transfer moving frame 210; a second vertical slide rail 232 is arranged on the second transfer moving frame 230, a second horizontal slot matching with the horizontal slide rail 130 is arranged at the bottom of the second cross beam 140, and a second vertical slot matching with the second vertical slide rail 232 is arranged on the side surface of the second cross beam 140 in contact with the second transfer moving frame 230.

[0123] The cooperation between the horizontal slide rail 130 and the first horizontal slot improves the stability of the second cross beam 140 moving horizontally along the rack 100, thereby improving the horizontal moving stability of the sheet transfer rack 200; the cooperation between the first vertical slide rail 212 and the first vertical slot improves the stability of the sheet transfer rack 200 rising or falling along the first cross beam 110. The above settings double ensure the safety and reliability of the sheet transfer rack 200 during transfer. Similarly, the horizontal slide rail 130 and the second horizontal slot improve the stability of the truss transfer rack 220 during horizontal movement, and the second vertical slide rail 232 and the second vertical slot improve the stability of the truss transfer rack 220 during lifting.

[0124] As an implementation manner, at least four adjusting feet are arranged at the bottoms of the truss placement rack 800, the sheet placement rack 300, and the support frame 400, and the adjusting feet are evenly arranged along the circumferences of the truss placement rack 800, the sheet placement rack 300, and the support frame 400. The adjusting feet can adjust the levels of the truss placement rack 800, the sheet placement rack 300, and the support frame 400, thereby ensuring the horizontal stability of the truss on the truss placement rack 800, the horizontal stability of the sheet on the sheet placement rack 300, and improving the horizontal stability between the truss and the sheet.

[0125] The usage method of this production line is as follows: Place the artificial or other machine trusses on the truss placement rack 800 for initial positioning of the trusses. After the truss transfer rack 220 clamps the required truss using the truss chuck, the truss transfer rack 220 moves horizontally along the machine frame 100 to above the truss limiting rack 500. The truss transfer rack 220 places the clamped truss into the truss limiting component to achieve the transfer and fixation of the truss. At the same time, the sheet transfer rack 200 clamps the sheet into the sheet placement rack 300, and uses the fixed plate 310, movable plate 320, first positioning plate 330, and second positioning plate 340 to achieve the initial positioning of the sheet. Subsequently, the sheet transfer rack 200 transfers the initially positioned sheet to above the already fixed truss to complete the transfer of the sheet. The sheet lifting seat 520 rises to lift the sheet until it is disengaged from the truss, and then the sheet is repositioned under the action of the sheet positioning component. After the sheet repositioning is completed, the sheet lifting seat 520 descends, and the sheet is placed back above the truss. The rotating motor drives the pressing block 730 to press the sheet above the second sheet limiting plate 640 and the support plate 630 to complete the assembly of the truss and the sheet. Finally, the telescopic rod 411 rises, and the second rotating motor rotates to drive the truss limiting rack 500 to move towards the punching, drilling, and locking mechanism 900. At this time, the rolling bearing 623 presses above the sheet to prevent the middle of the sheet from bulging, facilitating subsequent punching and drilling operations by the punching and drilling mechanism.
