Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 7, an intelligent flood prevention metal mesh welding manipulator according to an embodiment of the present invention includes a frame body 1 and a reciprocating driving member 2 disposed on the frame body 1 (the reciprocating driving member 2 may be a cam reciprocating mechanism, an air cylinder, a hydraulic cylinder, or other mechanism with a reciprocating function, and the mechanism with the reciprocating function is common knowledge in the art and is not described herein in detail), wherein a plurality of upper electrode blocks 3 are disposed at an output end of the reciprocating driving member 2 in parallel, a plurality of lower electrode blocks 4 are fixedly connected to the frame body 1 in parallel, the upper electrode blocks 3 and the lower electrode blocks 4 correspond to each other one by one to form a welding mechanism, and further includes a pressing member unit 5, the pressing member unit 5 includes a plurality of pairs of elastic members 50 connected to an output end of the reciprocating driving member 2, each elastic member 50 is provided with a pressing member 51 for pressing a workpiece to be welded, in the initial state, the pressing member 51 is positioned lower in height than the upper electrode block 3.

Specifically, in the actual production, the intermittent transportation of the longitudinal steel wire 8 is performed by an intermittent transportation mechanism, the intermittent transportation mechanism includes a geneva mechanism, a link mechanism, an incomplete gear mechanism, etc., which is not described in detail in the prior art, when the transportation of the longitudinal steel wire 8 is suspended at the intermittent place, one transverse steel wire 7 is transported between the upper electrode block 3 and the lower electrode block 4 by a mechanism special for transporting the transverse steel wire 7, and the transverse steel wire 7 is basically contacted with the longitudinal steel wire 8, but it is not excluded that the steel wire has local bending due to elasticity, so that a gap appears between the transverse steel wires, then the output end of the reciprocating driving member 2 moves downwards, and drives the upper electrode block 3 and the elastic member 50 to move towards the lower electrode block 4, because the position of the pressing member 51 is lower than the position of the upper electrode block 3 in the initial state, the pressing member 51 preferentially contacts the transverse steel wire 7, and gradually pressing the transverse steel wires 7 positioned at the two sides of the lower electrode block 4, so that the transverse steel wires 7 positioned between the upper electrode block 4 and the lower electrode block 4 can be bent by a certain radian, even if the transverse steel wires 7 are bent and deformed, the bending amplitude is small, after the pressing, the transverse steel wires 7 can be better in complete contact with the longitudinal steel wires 8, gaps are avoided, and after the pressing by the pressing piece 51, the stability of the welding of the transverse steel wires 7 and the longitudinal steel wires 8 can be ensured, then the pressing piece 51 cannot move downwards continuously after the pressing of the transverse steel wires 7 due to the obstruction of the transverse steel wires 7, at the moment, the pressing piece 51 reversely acts on the elastic piece 50, so that the elastic piece 50 is compressed, the upper electrode block 3 can move downwards continuously, thus the pressing piece 51 preferentially presses and pastes the transverse steel wires 7 on the longitudinal steel wires 8, and the upper electrode block 3 can be matched with the lower electrode block 4 after contacting the transverse steel wires 7, and (4) performing welding processing on the intersection of the transverse steel wire 7 and the longitudinal steel wire 8.

In the embodiment of the invention, by arranging the pressing piece 51, in the process that the reciprocating driving piece 2 drives the upper electrode block 3 to gradually approach the lower electrode block 4, the pressing piece 51 preferably and gradually presses the transverse steel wire 7, and the pressing piece 51 presses the transverse steel wire 7 from the transverse two sides of the upper electrode block 3, so that the pressing area of the transverse steel wire 7 is increased, the effect of tightly attaching the transverse steel wire 7 and the longitudinal steel wire 8 is better, a gap between the transverse steel wire and the longitudinal steel wire is eliminated, and the problem of insufficient welding is avoided.

Preferably, the elastic element 50 comprises a loop bar 500 connected with the output end of the reciprocating driving element 2, an inserted bar 501 is vertically arranged in the loop bar 500 in a sliding manner, the pressing element 51 is arranged at the lower end of the inserted bar 501, and a first spring is vertically arranged between the upper end of the inserted bar 501 and the loop bar 500; specifically, the insert rod 501 can vertically slide in the loop bar 500, and can generate a guiding effect when the pressing piece 51 presses the transverse steel wire 7, so that the position deviation of the pressing piece 51 is avoided, the transverse steel wire 7 is driven to deviate together when the pressing piece 51 is pressed, the mesh size of the welded metal mesh is uneven, after the pressing piece 51 is contacted with the transverse steel wire 7, the upper electrode block 3 cannot be moved downwards continuously, the insert rod 501 can move upwards in the loop bar 500 due to the reverse acting force of the transverse steel wire 7 on the pressing piece 51, the insert rod 501 extrudes the first spring, the pressure of the pressing piece 51 on the transverse steel wire 7 is exerted by the resilience of the first spring, and the transverse steel wire 7 to be welded is pressed.

The pressure applied by the pressing member 51 to the transverse steel wire 7 in the intelligent flood prevention metal mesh welding manipulator provided by the embodiment of the invention is from the rebound force generated when the first spring is extruded, so that the rebound force generated by the first spring is increased along with the extrusion of the first spring, the pressure applied by the pressing member 51 to the transverse steel wire 7 is increased, but in practice, the steel wire is subjected to elastic deformation (the elastic deformation is the elastic deformation generated by the pressing member 51 when the transverse steel wire 7 is welded, the elastic deformation does not enable the two ends of the transverse steel wire 7 to be incapable of being contacted with the longitudinal steel wire 8 at the edge of the metal mesh, and the required force is different when the transverse steel wire 7 and the longitudinal steel wire 8 are welded without performing false welding in advance, and the elastic deformation of the transverse steel wire 7 mentioned below is the same, and the needed force is different along with the increase of the rebound force of the first spring, the elastic deformation volume of some steel wires also can increase gradually, so just can make the crooked radian of the horizontal steel wire 7 that is in between the upper and lower electrode block 4 bigger and bigger, such condition can lead to the linear distance at horizontal steel wire 7 both ends to shorten, can appear the unable and vertical steel wire 8 contact that is in the metal mesh edge in both ends of horizontal steel wire 7, consequently need apply different pressure to the horizontal steel wire 7 of difference, in order to guarantee that the welding of horizontal steel wire 7 and vertical steel wire 8 can normally go on, and weld fashioned metal mesh can not appear quality problems (like rosin joint, the unable and vertical steel wire 8 contact that is in the metal mesh edge in horizontal steel wire 7 both ends, etc.).

Further, a balancing weight 52 is slidably arranged in the loop bar 500, and the balancing weight 52 is connected with the first elastic upper end; specifically, because the welding of the metal nets of each specification is mass production, according to the steel wires used by the metal nets of different specifications, the force required by the steel wire for generating elastic deformation is firstly determined, then the counterweight block 52 with matched weight is configured, the gravity of the counterweight block 52 generates downward pressure on the first spring, so that the first spring is compressed, initially, the pressing piece 51 is farthest away from the loop bar 500, thus after the pressing piece 51 presses the transverse steel wire 7, the pressing piece 51 cannot move downwards continuously, the insertion rod 501 moves upwards in the loop bar 500 in a reverse action manner, and at the moment, the pressure given to the transverse steel wire 7 by the pressing piece 51 is applied by the counterforce of the compressed first spring, after the insertion rod 501 moves upwards in the loop bar 500, the counterweight block 52 is driven to move upwards synchronously by the first spring, the compression amount of the first spring is kept unchanged due to the constant weight of the counterweight block 52, and the counterweight block cannot be limited at the top in the process of moving upwards relative to the loop bar 500, the pressing member 51 applies a constant pressure to the transverse wire 7, thereby avoiding the problem of an increasing curvature of the transverse wire 7 in the portion between the upper and lower electrode blocks 4.

Preferably, a first electromagnet 53 is arranged at the upper end of the loop bar 500, a second electromagnet 54 is arranged in the counterweight block 52, and the first spring is connected with a pressure detection mechanism; specifically, when welding different specifications metal mesh, need to change the balancing weight 52 of different weight, this kind of mode is too troublesome, be unfavorable for improving metal mesh welding shaping efficiency, and because some errors exist like frictional force, the gravity of balancing weight 52 is difficult to maintain invariable, so the power that will weld the steel wire that different metal mesh used and take place elastic deformation is input in pressure detection mechanism (pressure detection mechanism is pressure sensor, pressure sensor is known in the art general knowledge, do not do too much repeated here), like this when using different horizontal steel wires 7, the pressure that balancing weight 52 applyed to first spring is preferred to be set for well, first electro-magnet 53 and second electro-magnet 54 let in the electric current of different size or direction, in order to produce the magnetic force of attracting or repelling, thereby realize the gravity of control balancing weight 52.

When the force required by the elastic deformation of the transverse steel wire 7 is greater than the gravity of the counterweight block 52, the gravity of the counterweight block 52 needs to be increased, and at this time, the first electromagnet 53 and the second electromagnet 54 are both energized with current to generate magnetism, and the magnetic force generated by the first electromagnet 53 is repulsive to the magnetic force generated by the second electromagnet 54, and the magnetic force generated by the first electromagnet 53 is greater than the magnetic force generated by the second electromagnet 54, so that the counterweight block 52 is pressed downward, so that the first spring is compressed, and the force of the counterweight block 52 compressing the first spring can match the force required by the elastic deformation of the transverse steel wire 7, and as the inserted link 501 moves upward in the loop bar 500, the distance between the first electromagnet 53 and the second electromagnet 54 is shortened, so that the repulsive force of the first electromagnet 53 to the second electromagnet 54 is gradually increased, so that the pressure exerted by the counterweight block 52 to the first spring is increased, then the pressure detection mechanism detects the pressure change and transmits the signal to the control center, and the control center gives the signal to control the magnitude of the current introduced by the first electromagnet 53 so as to change the magnitude of the repulsive force of the first electromagnet to the second electromagnet 54, so that the counterweight block 52 can keep constant to the first spring pressure in the whole rising process, and the mode can realize the automatic adjustment of applying the counterweight block 52 to the first spring pressure and can more accurately provide pressure for the transverse steel wire 7.

Further, the pressing piece 51 comprises a pressing block 510 fixedly connected with the lower end of the inserting rod 501, a plurality of pressing rods 511 are slidably inserted in parallel on the bottom surface of the pressing block 510, and a second spring is connected between the pressing block 510 and the upper ends of the pressing rods 511; specifically, during the downward movement of the pressing block 510, the lower end of the pressing rod 511 is preferably in contact with the transverse steel wire 7, since the pressing rod 511 is slidably inserted on the pressing block 510, the transverse steel wire 7 gives an upward pressure to the pressing rod 511, so that the pressing rod 511 in contact with the transverse steel wire 7 moves upward until the pressing rod 511 located right above the transverse steel wire 7 can no longer move upward on the pressing block 510, and then the downward movement of the pressing block 510 makes the pressing rod 511 which can no longer move upward on the pressing block 510 press the transverse steel wire 7, while the other parts of the pressing rods 511 limit the transverse steel wire 7, thereby preventing the transverse steel wire 7 from moving transversely due to the pressure, the second spring is compressed by the pressure of the pressing rod 511, then the pressing block 510 moves upward without pressing the transverse steel wire 7, and the pressing rod 511 can return to the initial position again under the resilience of the second spring, the next use is not influenced.
