[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Two No. 3 electric rods are extended and retracted at the same time. The two No. 3 electric rods push the limit seats connected to them respectively. Under the elastic force of all No. 2 springs, all limit seats move relative to or towards each other at the same time, so as to adjust the distance between all limit seats, thereby presetting the distance between all steel wires;

[0028] 2. The No. 4 electric rod drives the fixed plate to move downward, and all the clamping components are pressed down to a predetermined height. At the same time, all hydraulic pumps inject hydraulic oil into the corresponding bases at the same time. At this time, under the push of hydraulic pressure, all sliding seats are pushed upward at the same time, and all sliding seats drive all limit seats to squeeze the steel wires upward, and all steel wires are positioned under the clamping force of all clamping components and all limit seats;

[0029] 3.

[0030] 4. The No. 5 electric rod pulls the fixed plate, and the fixed plate tightens the steel wire through the clamping assembly. Specifically, the clamp squeezes the steel wire. At this time, under the action of the squeezing force, part of the steel wire is sunken into the strip groove, thereby increasing the friction between the steel wire and the clamp, and increasing the limiting force on the steel wire; the No. 5 electric rod pulls the fixed plate, and at this time the fixed plate compresses the No. 3 spring, and the No. 3 spring pushes the clamp to tighten the steel wire. The elastic expansion and contraction of the No. 3 spring can avoid applying a rigid tension to the steel wire, causing the steel wire to break due to overwork; when the steel wire is sunken into the strip groove, the angle between the side wall of the strip groove close to the electric welding gun and the end face of the clamp is less than ninety degrees, which can further increase the limiting force of the strip groove on the steel wire;

[0031] 5. When the end face of the welding gun abuts against the intersection of the horizontal and vertical steel wires, the positioning grooves on all the positioning frames are clamped with the steel wires near the intersection of the horizontal and vertical steel wires. At this time, the No. 1 spring pushes the positioning block to abut against the steel wire vertically, and at the same time, the steel wire is horizontally limited through the positioning groove. The cooperation between the positioning groove and the positioning block increases the stability of the steel wire during welding;

[0032] 6. Before welding, the control system can realize the positioning and tightness adjustment of all steel wires by controlling the positioning components, hydraulic components, limit components, adjustment components and fixing mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

The limit seat 71 is slidably connected in the slide groove 13. The upper part of the limit seat 71 is provided with a limit groove 72 for limiting the steel wire.

[0054] In this embodiment, the steel wire is supported by the limiting seat 71 and limited by the limiting groove 72. The limiting groove 72 is arc-shaped, which can increase the contact area with the steel wire, thereby increasing the friction between the steel wire and the positioning effect of the steel wire.

[0055] like Figure 5As shown, a welding device for producing intelligent warehouse shelves provided by the present invention is shown, wherein the adjustment component 8 includes a slide plate 81, a second spring 82 and a third electric rod 83;

[0056] The side surfaces of both sides of the limit seat 71 are slidably connected with slides 81, and a No. 2 spring 82 is arranged between two adjacent limit seats 71. Both ends of the No. 2 spring 82 are connected to the slides 81 on both sides. Fixed seats 14 are arranged at both ends of the base 11, and a retractable No. 3 electric rod 83 is connected between the fixed seat 14 and the slide 81 on one side.

[0058] like Figure 3 As shown, a welding device for producing smart warehouse shelves provided by the present invention is provided, wherein the hydraulic assembly 6 includes an oil tank 61 and a hydraulic pump 62, wherein the oil tank 61 is fixedly connected to the workbench 1, and the hydraulic pump 62 is connected between the oil tank 61 and a base 11 on one side.

[0059] In this embodiment, the hydraulic pump 62 is started and can extract or inject hydraulic oil into the base 11. Under the push of the hydraulic oil, all the sliding seats 12 are simultaneously vertically extended and retracted. Through the push of the sliding seats 12, all the limit seats 71 and all the fixing mechanisms 9 can clamp the steel wire together.

[0060] like Figure 2 As shown, a welding device for producing intelligent warehouse shelves provided by the present invention is provided, wherein the positioning assembly 4 includes a positioning frame 41, a positioning groove 42, a No. 1 spring 43 and a positioning block 44;

[0061] The welding gun 10 is fixedly connected to a plurality of rectangular positioning frames 41 , each positioning frame 41 is provided with a positioning slot 42 , a positioning block 44 is slidably connected in the positioning slot 42 , and a spring 43 is connected between the positioning block 44 and the inner end surface of the positioning slot 42 .

[0062] In this embodiment, when the electric welding gun 10 moves downward, the electric welding gun 10 drives all the positioning frames 41 to move downward, and the positioning grooves 42 on all the positioning frames 41 are engaged with the steel wires near the intersection of the horizontal and vertical steel wires. At this time, the No. 1 spring 43 pushes the positioning block 44 to vertically abut the steel wire, and at the same time, the steel wire is horizontally limited by the positioning groove 42. The cooperation between the positioning groove 42 and the positioning block 44 increases the stability of the steel wire during welding.

[0063] like Figure 3 As shown, a welding device for producing intelligent warehouse shelves provided by the present invention, the fixing mechanism 9 includes a No. 4 electric rod 91, a No. 5 electric rod 92, a fixing plate 93 and a clamping assembly 94;

[0064] A retractable No. 4 electric rod 91 is provided on the side of the sliding seat 12 away from the card slot 5, and the No. 4 electric rod 91 is fixedly connected to the end face of the workbench 1, and the retractable end of the No. 4 electric rod 91 is fixedly connected to a retractable No. 5 electric rod 92, and the retractable end of the No. 5 electric rod 92 is fixedly connected to a fixing plate 93, and a clamping assembly 94 for fixing the steel wire is provided in the fixing plate 93.

[0065] In this embodiment, the fourth electric rod 91 is started to retract, the fourth electric rod 91 drives the fixed plate 93 to move downward, and the fixed plate 93 drives the clamping assembly 94 to fix the steel wire; the fifth electric rod 92 is started to retract, the fifth electric rod 92 pulls the fixed plate 93, and the fixed plate 93 tightens the steel wire through the clamping assembly 94.

[0066] like Figure 6 As shown, a welding device for producing intelligent warehouse shelves provided by the present invention is shown, wherein the clamping assembly 94 includes a clamping plate 941, a strip groove 942 and a No. 3 spring 943;

[0067] The end surface of the fixing plate 93 facing the base 11 is slidably connected with a clamping plate 941 , and a plurality of strip grooves 942 are arranged at equal intervals in the clamping plate 941 . A plurality of No. 3 springs 943 are arranged between the clamping plate 941 and the inner end surface of the fixing plate 93 .

[0068] In this embodiment, the clamping plate 941 squeezes the steel wire. At this time, under the action of the squeezing force, part of the steel wire is recessed into the strip groove 942, thereby increasing the friction between the steel wire and the clamping plate 941, and increasing the limiting force on the steel wire; when the No. 5 electric rod 92 contracts, the No. 5 electric rod 92 pulls the fixed plate 93. At this time, the fixed plate 93 compresses the No. 3 spring 943, and the No. 3 spring 943 pushes the clamping plate 941 to tighten the steel wire. The elastic expansion and contraction of the No. 3 spring 943 can avoid applying rigid tension to the steel wire, causing the steel wire to break due to overwork.

[0069] like Figure 7As shown, a welding device for producing smart warehouse shelves provided by the present invention is provided, wherein the angle between the side wall of the strip groove 942 close to the welding gun 10 and the end surface of the clamping plate 941 is less than ninety degrees.

[0070] In this embodiment, when the steel wire is recessed into the strip groove 942 , the angle between the side wall of the strip groove 942 close to the welding gun 10 and the end surface of the clamping plate 941 is less than ninety degrees, which can further increase the limiting force of the strip groove 942 on the steel wire.

[0071] like Figure 8 As shown, a welding device for producing intelligent warehouse shelves provided by the present invention, the control system includes:

[0072] The monitoring module includes a plurality of No. 1 pressure sensors and a plurality of No. 2 pressure sensors. The end surface of the positioning block 44 facing the outer side of the positioning groove 42 is provided with a No. 1 pressure sensor, and the inner side wall of the positioning groove 42 is provided with a No. 2 pressure sensor;

[0073] A storage module, which is used to store the pressure values ​​of all No. 1 pressure sensors and all No. 2 pressure sensors;

[0074] A processing module, which is used to compare the pressure values ​​of all the No. 1 pressure sensors and all the No. 2 pressure sensors with the corresponding pressure thresholds and form judgment information; the processing module is preferably a computer processor;

[0075] The control module is used to receive the judgment information and control the positioning component 4, the hydraulic component 6, the limit component 7, the adjustment component 8 and the fixing mechanism 9; the control module is preferably a PLC controller.

[0076] In this embodiment, when the pressure value of the No. 1 pressure sensor is less than the preset pressure threshold, it means that the tension of the steel wire on the corresponding side is not enough, resulting in the steel wire being loose. The processing module controls the No. 4 electric rod 91 on the corresponding side of this section of steel wire to start and contract, thereby increasing the fixing force on the steel wire; in addition, the processing module controls the No. 5 electric rod 92 to start contraction, the No. 5 electric rod 92 pulls the fixing plate 93, and the fixing plate 93 pulls the clamping assembly 94 to tighten the steel wire, thereby increasing the pre-tightening force of the steel wire;

[0077] When the pressure value of the No. 2 pressure sensor exceeds the preset pressure threshold, it means that both ends of the steel wire are tilted horizontally. The processing module controls the No. 3 electric rod 83 on the base 11 at one end of the steel wire to start, and the telescopic movement of the two No. 3 electric rods 83 on the base 11 pushes all the limit seats 71 to move, thereby adjusting the parallelism of the steel wire.

[0078] Working principle:

[0079] The two No. 3 electric rods 83 at both ends of the base 11 are started, and the two No. 3 electric rods 83 are extended and retracted at the same time, and the two No. 3 electric rods 83 push the limit seats 71 connected thereto respectively, and under the elastic force of all No. 2 springs 82, all the limit seats 71 move relative to or towards each other at the same time, so as to adjust the distance between all the limit seats 71, thereby presetting the distance between all the steel wires;

[0080] Place the frame in the slot 5, and then set a number of steel wires on the upper side of the frame in the horizontal and vertical directions, with both ends of all the steel wires passing through the limiting slots 72 on the corresponding sides respectively;

[0081] Start the fourth electric rod 91 to retract, the fourth electric rod 91 drives the fixed plate 93 to move downward, all the clamping components 94 are pressed down to a predetermined height, and at the same time all the hydraulic pumps 62 inject hydraulic oil into the corresponding base 11. At this time, under the push of the hydraulic pressure, all the sliding seats 12 are pushed upward at the same time, and all the sliding seats 12 drive all the limit seats 71 to squeeze the steel wires upward, and all the steel wires are positioned under the clamping force of all the clamping components 94 and all the limit seats 71;

[0082] Through the push of the sliding seat 12, all the limit seats 71 and all the clamping components 94 clamp the steel wires together, and under the action of the hydraulic oil, all the limit seats 71 can maintain the same pressure on the steel wires of different diameters, thereby improving the fixing effect of all the steel wires and avoiding the diameter error between the steel wires causing some of the steel wires to be not firmly fixed;

[0083] The fifth electric rod 92 is started to contract, and the fifth electric rod 92 pulls the fixed plate 93, and the fixed plate 93 tightens the steel wire through the clamping assembly 94. Specifically, the clamping plate 941 squeezes the steel wire. At this time, under the action of the squeezing force, part of the steel wire is recessed into the strip groove 942, thereby increasing the friction between the steel wire and the clamping plate 941, and increasing the limiting force on the steel wire; when the fifth electric rod 92 is contracted, the fifth electric rod 92 pulls the fixed plate 93, and at this time the fixed plate 93 compresses the third spring 943, and the third spring 943 pushes the clamping plate 941 to tighten the steel wire. The elastic expansion and contraction of the third spring 943 can avoid applying a rigid tension to the steel wire, causing the steel wire to break due to overwork; when the steel wire is recessed into the strip groove 942, the angle between the side wall of the strip groove 942 close to the electric welding gun 10 and the end face of the clamping plate 941 is less than ninety degrees, which can further increase the limiting force of the strip groove 942 on the steel wire;

[0084] At this time, the No. 1 electric rod 2 is started to move downward, and the No. 1 electric rod 2 drives the guide rail 15 to move downward. Through the cooperation of the No. 6 electric rod 16 and the No. 2 electric rod 3, the electric welding gun 10 can be freely moved in the horizontal position, and the intersection of the steel wires in the horizontal and vertical directions is welded by the electric welding gun 10;

[0085] When the end face of the electric welding gun 10 abuts against the intersection of the horizontal and vertical steel wires, the positioning grooves 42 on all the positioning frames 41 are engaged with the steel wires near the intersection of the horizontal and vertical steel wires. At this time, the first spring 43 pushes the positioning block 44 to abut against the steel wire vertically, and at the same time, the steel wire is horizontally limited by the positioning groove 42. The cooperation between the positioning groove 42 and the positioning block 44 increases the stability of the steel wire during welding.

[0086] Before welding, the control system can realize the positioning and tightness adjustment of all steel wires by controlling the positioning component 4, the hydraulic component 6, the limit component 7, the adjustment component 8 and the fixing mechanism 9;

[0087] After welding is completed, the cover plate is fixed on the frame to fix the welded wire mesh to the frame.
