[0030] Reference Figure 1 and Figure 2In an embodiment of the present application, the intelligent device for assisting workers to weld the roof frame of the steel structure box includes a longitudinal beam loading device, a cross beam loading device 10 and a tooling jig frame 20. The cross beam loading device 10 includes a cross beam storage table 11, a cross beam grabbing mechanism 12 and a cross beam tooling chain group 13. The cross beam storage table 11 is used to store the cross beams of the roof frame.

The longitudinal beam limiting tooling clamp 24 is provided with a clamping position for clamping the longitudinal beam, so as to limit the position of the longitudinal beam in the horizontal plane.

[0031] In the present application, the longitudinal beam loading device can adopt a longitudinal beam lifting and translating device, which can adopt an existing device and will not be described here.

The cross beam storage table 11 can be arranged on one side of the cross beam tooling chain group 13. The cross beam grabbing mechanism 12 can be arranged above the cross beam storage table 11 and the cross beam tooling chain group 13 to facilitate the picking and placing of cross beams between the two.

The cross beam tooling chain group 13 is arranged on the cross beam tooling lifting mechanism 23 of the tooling jig frame 20. The longitudinal beam limiting tooling clamp 24 can be arranged at the corner outside the cross beam limiting tooling clamp 22, which is not limited here.

[0033] In the present application, the cross beam grabbing mechanism 12 is adopted to realize the automatic loading of the cross beams of the roof frame. The cross beam tooling chain group 13, the cross beam limiting tooling clamp 22, the cross beam tooling lifting mechanism 23 and the longitudinal beam limiting tooling clamp 24 are arranged to adjust the cross beams and longitudinal beams to the target position for welding and assembling the roof frame, which greatly improves the efficiency of the roof frame assembly and saves the labor cost.

[0034] It should be noted that the longitudinal beams of the roof frame can be loaded by manual loading or by using a cross beam grabbing mechanism similar to the cross beam grabbing mechanism, which is not limited here.

[0035] Please refer to Figure 1In an embodiment, the beam grabbing mechanism 12 can include a support 121, a fixing frame 122 movably hung below the support 121 along the length and width of the beam storage platform 11, a first driving member (not shown in the figure) and at least one pair of clamping jaws (not shown in the figure) arranged on the fixing frame 122 and drivingly connected with the first driving member, and the first driving member is used to drive the clamping jaws to grab the beams. In this way, the beams can be clamped to the beam tool chain group 13, greatly improving the production efficiency.

[0036] In the embodiment, the clamping jaws can be hollow long plates so as to clamp multiple beams at the same time. The clamping jaws can be connected with rotating shafts through multiple interval arranged swing arms, and the rotating shafts can be connected with the first driving member such as a cylinder or a motor through a transmission member, which is not limited here.

[0037] In an embodiment, the device can further include a material bearing plate for bearing the beams, and the material bearing plate is arranged on the beam storage platform 11.

[0038] In the assembly preparation stage, a certain number of top frame beams can be placed on a material bearing plate in advance, and each beam is arranged in a pair of material bearing plate clamping grooves. Among them, the posture of any two beams on the material bearing plate is the same, and the distance between any two adjacent beams is a constant value.

[0039] Further, the material bearing plate can be provided with an electronic tag recording the beam information, and the clamping jaws are provided with an electronic information reader for identifying the beam length signal recorded in the electronic tag of the material bearing plate.

[0040] In the embodiment, the device can further include a controller, and the controller is signal connected with the electronic information reader and the first driving member respectively, so as to control the first driving member to adjust the clamping distance of the clamping jaws according to the beam length signal to match the length of the beam.

[0041] In addition, the controller can also control other mechanisms to work, so as to improve the automation degree of the device, thereby further improving the production efficiency and reducing the labor cost. The controller can be signal connected with the beam tool lifting mechanism 23, the beam limiting tool clamp 22 and the longitudinal beam limiting tool clamp 24 respectively. The controller is also used to control the beam tool lifting mechanism 23 to adjust the position of the beam in the height direction of the tool bed 20 according to the obtained production order information, and can control the beam limiting tool clamp 22 to limit the position of the beam in the horizontal plane, and control the longitudinal beam limiting tool clamp 24 to limit the position of the beam in the horizontal plane.

[0042] Among them, the controller can be a PLC controller, which is not limited here.

[0043] In the process of assembling the roof frame of the house, first, the operator can drive the forklift to lift the full load of the material plate and transport it above the crossbeam storage table 11 at the starting end of the crossbeam feeding device 10, and then slowly lower the steel fork to make the material plate fall on the crossbeam storage table 11. Then, the clamping jaw above the crossbeam storage table 11 reads the crossbeam electronic information recorded by the electronic tag of the material plate through the built-in electronic information reader, and the crossbeam grabbing mechanism 12 automatically adjusts the distance between the two clamping jaws according to the length information of the crossbeam to match the length of the crossbeam. Then the clamping jaw is automatically lowered and tightened to clamp both ends of all crossbeams on the material plate, and then all crossbeams are placed on the crossbeam tool chain group 13 through the actions of vertical lifting, translation, vertical lowering, and loosening the clamping jaw. The crossbeam tool chain group 13 synchronizes the crossbeam spacing information contained in the crossbeam electronic information, and the crossbeam tool chain group 13 moves apart and drives all crossbeams to be evenly distributed above the roof frame welding tool jig 20, and finally the crossbeam tool chain group 13 is lowered again through the crossbeam tool lifting mechanism 23 until all crossbeams fall on the tool jig 20.

[0044] Reference Figure 2 and Figure 3 In an embodiment, the crossbeam tool chain group 13 can include a base 131, a plurality of movable clamping pieces 132, and a second driving piece 134 drivingly connected with the movable clamping pieces 132. The plurality of movable clamping pieces 132 are slidingly arranged on the base 131 and move under the driving of the second driving piece 134, and adjacent two movable clamping pieces 132 are connected by a chain.

[0045] In this embodiment, the base 131 can be provided with a sliding groove extending along the length direction thereof, and the movable clamping piece 132 is provided with a sliding block slidingly arranged in the sliding groove.

[0046] In this embodiment, the movable clamping piece 132 can include a strip-shaped plate and a tooth block 133 arranged at both ends of the strip-shaped plate, and the tooth block 133 constitutes a clamping position for placing the crossbeam.

[0047] The length of each chain is the same, and the length can be equal to the spacing between adjacent two crossbeams, so as to ensure that the movable clamping pieces 132 can be evenly spread apart to match the spacing requirement of the crossbeams. The spacing adjustment between adjacent two clamping positions can be realized by changing the length of the chain to adapt to the production requirements of different houses.

[0048] In some embodiments, the device can further include a conveying mechanism for conveying the welded roof frame to the next station to facilitate the next step of processing and improve the efficiency of production and manufacturing.

[0049] The above merely describes optional embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
