In addition, the opposite ends of the first rail 114 and the opposite ends of the second rail 115 are respectively slidably connected to the sliding guide rails forming the first enclosing frame 116 to adjust the positions of the first rail 114 and the second rail 115. In the current embodiment, four first rails 114 are provided, two second rails 115 are provided, and the first rail 114 abuts against the upper surface of the second rail 115.

The first positioning block 111 further includes two opposite second plates 1112, and the second plates 1112 are arranged in a U-shaped manner and span across the two first plates 1111 at intervals and are located between the two first protrusions, and the two second plates 1112 are respectively slidably connected to the two sides of the second rail 115; in order to ensure the stability of movement, a convex block can also be provided on one of the second plate 1112 and the second rail 115, and a sliding groove matching the convex block is provided on the other. The first plate 1111 and the second plate 1112 can include but are not limited to being detachably connected by screwing, etc. Further, in order to facilitate the fixing of the steel bars placed on the first plate 1111 and the second plate 1112, magnets 13 are provided on the first protrusions of the first plate 1111, and magnets 13 are provided on the vertical plates of the U-shaped second plates 1112, so as to stably place the steel bars on the first plate 1111 and the second plate 1112, and enable multiple steel bars to form a parallelogram on the first positioning block 111.

[0055] To ensure the movement of the first rail 114 and the second rail 115, the side net positioning assembly 11 further includes a first driving member 112 and a second driving member 113. The output end of the first driving member 112 is connected to the first rail 114, and the output end of the second driving member 113 is connected to the second rail 115. The first driving member 112 drives the first rail 114 to drive the first positioning block 111 to move along the second rail 115, while the output end of the second driving member 113 is connected to the second rail 115, and the second driving member 113 drives the second rail 115 to drive the first positioning block 111 to move along the first rail 114, so as to adjust the spacing of the steel bars. It should be noted here that the forms of the first driving member 112 and the second driving member 113 are not specifically limited, and common transmission structures such as a combination of a motor, a gear and a chain, a combination of a motor and a conveyor belt, or a combination of a motor and a lead screw can be used. In this embodiment, the form of a motor and a lead screw is adopted. The motor is connected to the lead screw, and a nut is arranged on the lead screw.

In some embodiments, the first rail 114 and the first driving member 112 are arranged in one-to-one correspondence, and the second rail 115 and the second driving member 113 are arranged in one-to-one correspondence; in other embodiments, one first driving member 112 and one second driving member 113 can be provided, and a synchronous gear set is arranged at the output ends of the first driving member 112 and the second driving member 113. A plurality of first rails 114 and a plurality of second rails 115 are respectively connected to the first driving member 112 or the second driving member 113 through the synchronous gear set, so as to synchronously adjust the plurality of first rails 114 and synchronously adjust the plurality of second rails 115. The synchronous gear set is a prior art, and the specific structure will not be elaborated.

[0056] As Figure 2 and Figure 4 shown, in some embodiments, the bottom net positioning assembly 12 includes a second enclosing frame 124. A third rail 123 is arranged in the second enclosing frame 124 and is distributed at intervals along the first direction. Each third rail 123 extends along the third direction (the second direction is Figure 2In the Z direction, since the steel bars on the bottom mesh 200 are horizontally and vertically perpendicular steel bars; thus, in the current embodiment, the third direction is perpendicular to the first direction. The second positioning blocks 121 are arranged on the third rail 123, so as to position the steel bars forming the bottom mesh 200 through a plurality of second positioning blocks 121. In the current embodiment, in order to form the above-mentioned bottom mesh 200, the second positioning block 121 includes fourth plates 1211 arranged at intervals. The fourth plates 1211 are located on both sides of the third rail 123. Second protrusions are arranged at intervals on each fourth plate 1211. The two second protrusions are distributed at intervals along the length direction of the fourth plate 1211. One of the second protrusions is located at the first end of the fourth plate 1211, and there is a distance between the other second protrusion and the second end of the fourth plate 1211, that is, a steel bar can be placed between one of the second protrusions and the second end of the fourth plate 1211; fifth plates 1212 are also arranged on the two fourth plates 1211. The fifth plates 1212 are arranged between the two second protrusions. Two groups of opposite L-shaped protrusions are provided on the fifth plates 1212. One side of the L-shaped protrusion is flush with the fifth plate 1212, and the other side of the L-shaped protrusion protrudes in the same direction as the second protrusion, so that a plurality of steel bars are enclosed into a square shape on the second positioning block 121. In addition, the bottom mesh positioning assembly 12 is also provided with a third driving member 122. The output end of the third driving member 122 is connected to the above-mentioned second positioning block 121, so as to adjust the position of the second positioning block 121 on the third rail 123 and ensure the welding quality. The form of the third driving member 122 is not specifically limited. In the current embodiment, the common form of a motor and a lead screw is adopted. In the current embodiment, in order to ensure the stability of the movement of the second positioning block 121, a slideway is provided on one of the side parts of the third rail 123 or the fourth plate 1211, and a sliding protrusion is provided on the other one.

[0057] Further, in order to facilitate the fixing of the steel bars placed on the fourth plates 1211 and the fifth plates 1212, magnets 13 are arranged on the second protrusions of the fourth plates 1211 and the L-shaped protrusions of the fifth plates 1212 to facilitate the fixing of the steel bars.

[0058] In some other embodiments, in order to form a closed bottom net 200, the bottom net positioning assembly 12 may also include a second enclosing frame 124 composed of sliding rails. At the same time, it also includes a fourth rail disposed in the second enclosing frame 124. The third rail 123 is disposed in the second enclosing frame 124 and intersects with the fourth rail. Both opposite ends of the third rail 123 and the fourth rail are respectively slidably connected to the sliding guide rails forming the second enclosing frame 124. A second positioning block 121 as described above is disposed at the intersection between the third rail 123 and the fourth rail. The second positioning block 121 may adopt the same structure as the first positioning block 111. In order to facilitate driving the sliding of the third rail 123 and the fourth rail, the bottom net positioning assembly 12 further includes a fourth driving member. The output end of the third driving member 122 is connected to the third rail 123 to be able to drive the third rail 123 to drive the second positioning block 121 to slide along the fourth rail; the output end of the fourth driving member is connected to the fourth rail to be able to drive the fourth rail to drive the second positioning block 121 to slide along the third rail 123. The third rail 123 and the fourth rail may adopt the same moving structure as the first rail 114 and the second rail 115, which will not be specifically described herein.

[0059] Such as Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, the first welding mechanism 2 is disposed on one side of the bottom net positioning assembly 12 or the side net positioning assembly 11 to be able to weld the intersection points of the steel bars positioned on the first positioning block 111 and the second positioning block 121 to form the bottom net 200 and the side net 100. Specifically, the first welding mechanism 2 includes a first welding driving member 21 and a first welding rail 24. The first welding rail 24 extends along a first direction. A first welding seat 25 is provided on the first welding rail 24. The first welding seat 25 is connected to the output end of the first welding driving member 21. Thus, the first welding driving member 21 drives the first welding seat 25 to move along the first welding rail 24. Two spaced-apart first welding heads 22 and two spaced-apart second welding heads 23 are provided on the first welding seat 25. Among them, the first welding heads 22 and the second welding heads 23 are arranged vertically opposite to each other. The first welding heads 22 and the second welding heads 23 are respectively connected to the positive electrode and the negative electrode of the transformer. Thus, a circuit is formed when the first welding heads 22 and the second welding heads 23 come into contact. In addition, a first welding cylinder 26 corresponding to the first welding heads 22 and the second welding heads 23 is further provided on the first welding seat 25. Each first welding head 22 and each second welding head 23 are provided at the output end of the first welding cylinder 26. Thus, the first welding cylinder 26 is used to drive the first welding heads 22 and the second welding heads 23 to approach each other to clamp the steel bars for welding. Further, in order to adapt to the spacing between different intersections of steel bars, the first welding mechanism 2 further includes a first distance adjustment driving member 28. A first distance adjustment driving member 28 is correspondingly provided for each of the two first welding heads 22 and the two second welding heads 23. Hereinafter, taking the first welding head 22 as an example for illustration, two racks 27 are respectively provided on the two first welding cylinders 26 connecting the two first welding heads 22. The two racks 27 are arranged oppositely. A gear is provided at the output end of the first distance adjustment driving member 28. The gear meshes with the two racks 27. Thus, during the rotation of the gear, the spacing between the two first welding heads 22 is adjusted so that the two first welding heads 22 correspond to the welding points of steel bars with different spacings. In addition, in order to ensure the stability of the movement, a guide shaft 29 is passed through the two first welding cylinders 26. Thus, the two first welding cylinders 26 move along the guide shaft 29. Similarly, the second welding heads 23 can be arranged according to the above structure. Exemplarily, the first distance adjustment driving member 28 is a servo motor.

[0060] As Figure 1 and Figure 2As shown above, based on the above, the first welding mechanism 2 is disposed on one side of the bottom net positioning component 12 or the side net positioning component 11. Therefore, it is necessary for the bottom net positioning component 12 and the side net positioning component 11 to carry the positioned steel bars to the first welding mechanism 2 in turn for welding. Thus, the positioning die mechanism 1 further includes a translation driving member 15, and the translation driving member 15 is respectively connected to the bottom net positioning component 12 and the side net positioning component 11, so as to drive the two to exchange positions, and then be welded by the first welding mechanism 2. Specifically, the positioning die mechanism 1 further includes a conversion frame 14. The conversion frame 14 is provided with two sets of conversion rails. One set of conversion rails is located on the relative inner side of the conversion frame 14, and the other set of conversion rails is located on the top of the conversion frame 14. The first enclosing frame 116 of the bottom net positioning component 12 and the second enclosing frame 124 of the side net positioning component 11 respectively slide on the above two sets of conversion rails. Exemplarily, two translation driving members 15 can be provided, and the two translation driving members 15 are respectively connected to the first enclosing frame 116 and the second enclosing frame 124, so as to drive the two to move in opposite directions. The translation driving member 15 can adopt a combination of a motor, a gear and a driving chain, and both the first enclosing frame 116 and the second enclosing frame 124 are arranged on the driving chain.

[0061] Furthermore, in order to avoid interference between the bottom net positioning component 12 and the side net positioning component 11 when changing positions, the positioning die mechanism 1 further includes a lifting driving member 16. The lifting driving member 16 is connected to the bottom net positioning component 12 and / or the side net positioning component 11, so as to drive at least one of the bottom net positioning component 12 and the side net positioning component 11 to lift, so as to be able to avoid the other. In some embodiments, the lifting driving member 16 slides on one set of conversion rails. The lifting driving member 16 is a lifting cylinder, and the output end of the lifting cylinder is connected to the first enclosing frame 116, so as to be able to drive the first enclosing frame 116 to lift to avoid the translation of the second enclosing frame 124; of course, the second enclosing frame 124 can also be arranged at the output end of the lifting driving member 16, so as to drive the second enclosing frame 124 to lift to avoid the translation of the first enclosing frame 116.

[0062] After both the side net 100 and the bottom net 200 are welded, the side net 100 and the bottom net 200 can be welded to form a positioning mesh sheet. Based on this, the positioning mesh sheet welding equipment further includes a fixing mechanism 7 and a transfer manipulator 6. The transfer manipulator 6 moves the bottom net 200 to the fixing mechanism 7 for fixing, and then clamps the side net 100 and the above bottom net 200 for docking. The fixing mechanism 7 and the transfer manipulator 6 are both prior arts, and the specific structures will not be elaborated.

[0063] As Figure 1 、 Figure 7 and Figure 8As shown in the figure, the positioning mesh welding device is further provided with a second welding mechanism 3 for welding the intersections of the bottom mesh 200 and the side mesh 100. The second welding mechanism 3 and the first welding mechanism 2 are located on both sides of the positioning die mechanism 1 to avoid interference. Specifically, the second welding mechanism 3 includes a second welding driving member 31 and a second welding rail 34. The second welding rail 34 also extends along the first direction. A second welding seat 35 is provided on the second welding rail 34. The second welding seat 35 is arranged at the output end of the second welding driving member 31. The second welding driving member 31 drives the second welding seat 35 to move along the second welding rail 34. The second welding seat 35 is provided with an upper and a lower opposite third welding head 32 and a fourth welding head 33. One of the third welding head 32 and the fourth welding head 33 is connected to the positive pole of the transformer, and the other is connected to the negative pole of the transformer. The third welding head 32 and the fourth welding head 33 can approach or move away from each other to clamp the intersection between the bottom mesh 200 and the side mesh 100 for welding. A second welding cylinder 36 corresponding to the third welding head 32 and the fourth welding head 33 can be provided on the second welding seat 35, so that the third welding head 32 and the fourth welding head 33 are respectively arranged on the second welding cylinder 36, and the second welding cylinder 36 is used to drive the two to approach or move away from each other.

[0064] Furthermore, the third welding head 32 and the fourth welding head 33 can move in a direction close to or away from the second welding rail 34 to adapt to the intersections of the bottom mesh 200 and the side mesh 100. Specifically, taking the movement of the third welding head 32 as an example, an installation frame 37 is provided on the second welding seat 35. A second adjustment driving member 38 is provided on the installation frame 37. Specifically, the second adjustment driving member 38 includes a driving motor. The output end of the driving motor is provided with a lead screw. The lead screw extends in a direction close to or away from the second welding rail 34 and rotates on the installation frame 37. A nut is provided on the lead screw. The second welding cylinder 36 is arranged on the nut. Thus, the rotation of the lead screw drives the second welding cylinder 36 to move, and further drives the third welding head 32 arranged at the output end of the second welding cylinder 36 to move. Similarly, the fourth welding head 33 can be driven by the same structure as the third welding head 32, and details are not described herein again.

[0065] As Figure 1 shown, it can be understood that the positioning mesh welding device further includes a control system, which is respectively communicatively connected to the steel bar cutting mechanism 4, the steel bar storage mechanism, the steel bar placing manipulator 5, the positioning die mechanism 1, the first welding mechanism 2 and the second welding mechanism 3 for automatic control; the control system can but is not limited to adopt a PLC control system.

[0066] A positioning mesh welding method uses the above-mentioned positioning mesh welding device, and includes the following steps:

[0067] The steel bar cutting mechanism 4 cuts the steel bars and places the cut steel bars into the steel bar storage mechanism;

[0068] Place the steel bars on the first positioning block 111 and the second positioning block 121 for positioning; specifically, the steel bar placing manipulator 5 places the stored steel bars on a number of first positioning blocks 111 of the side net positioning assembly 11 and a number of second positioning blocks 121 on the bottom net positioning assembly 12 for fixing;

[0069] After the steel bars are fixed, the first welding mechanism 2 can weld the intersecting steel bars on the placed side net positioning assembly 11 or bottom net positioning assembly 12 to form the bottom net 200 or the side net 100; it should be noted here that no matter which one of the side net positioning assembly 11 or bottom net positioning assembly 12 is placed first, after placement, the first welding mechanism 2 can be used for welding. While welding, the other one of the side net positioning assembly 11 or bottom net positioning assembly 12 can be placed, and then the two can be replaced in position by the translation driving member 15 and the lifting driving member 16 to perform welding again, improving efficiency.

[0070] The transfer manipulator 6 transfers the welded bottom net 200 to the fixing mechanism 7 for fixing, and then grabs the side net 100 and the bottom net 200 for docking;

[0071] The second welding mechanism 3 welds the docking points between the connected bottom net 200 and side net 100 to form a complete positioning mesh sheet.

[0072] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
