DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] like Figure 1-Figure 10 As shown, this embodiment provides a photovoltaic bracket welding device for welding Fig.11 The bracket shown in the device includes a vertical bracket feeding part 100, a bracket base feeding part 200 and a welding part 300 arranged in sequence, and the welding part 300 is located at one end of the vertical bracket feeding part 100 facing the bracket base feeding part 200.

[0037] Specifically, Figure 6As shown, the vertical bracket feeding part 100 includes a group of support seats 110, each of which is provided with a moving plate 120. When in use, the vertical bracket 1 is horizontally placed on the top surface of the moving plate 120, and the opening of the vertical bracket 1 is facing downward, so that the top surface of the moving plate 120 supports the horizontal part of the inner wall of the vertical bracket 1. A stepping mechanism 130 is provided between the group of support seats 110, which is used to push the vertical brackets 1 placed on the top surface of the moving plate 120 one by one upward and forward to the end of the moving plate 120 facing the bracket base feeding part 200.

[0038] like Figure 7 As shown, the top of the movable plate 120 is recessed downward and provided with a slide groove 121, the length direction of the slide groove 121 is consistent with the length direction of the movable plate 120, and a stopper 140 is vertically telescopically provided in the slide groove 121, and the distance between the stopper 140 and one end of the movable plate 120 toward the feed part 200 of the bracket base is consistent with the length of the vertical bracket 1; under normal circumstances, the top of the stopper 140 protrudes upward from the top surface of the movable plate 120. In order to avoid interference between the movement of the stopper 140 and the vertical bracket 1 when the stepping mechanism 130 pushes the vertical bracket 1 to move to one end of the movable plate 120, the height of the stopper 140 protruding from the top surface of the movable plate 120 is less than the height of the vertical bracket 1 pushed upward by the stepping mechanism 130.

[0039] When the vertical bracket 1 moves to the top of the material stopper 140, the top of the material stopper 140 is subjected to the pressure of the vertical bracket 1, so that the material stopper 140 is retracted downward along the slide groove 121 into the slide groove 121; when the vertical bracket 1 moves over the top of the material stopper 140, the material stopper 140 automatically extends upward from the slide groove 121. At this time, the stepping mechanism 130 pauses, the vertical bracket 1 is sent into the welding area, and the material stopper 140 facing the welding area is automatically limited to the end of the vertical bracket 1 facing the material stopper 140, so as to avoid the vertical bracket 1 moving along the length direction of the movable plate 120 in the subsequent welding process, affecting the welding quality, and a group of support seats 110 are vertically provided with a downward pressure cylinder 113 on the outer side, and the output end of the downward pressure cylinder 113 is vertically upward, and the output end of the downward pressure cylinder 113 is provided with a pressing plate 114. When the vertical bracket 1 moves to the welding area, the pressing plate 114 is used to move downward to press the top surface of the horizontal part of the vertical bracket 1 to ensure that the horizontal part of the vertical bracket 1 remains horizontal.

[0040] like Figure 1As shown, the support base feeding part 200 includes an annular conveying chain 210, a positioning seat 220 arranged in an array along the outer periphery of the annular conveying chain 210, an adjustment plate 230 arranged on both sides of the positioning seat 220, and a stopper 240 arranged at one end of the positioning seat 220. The length direction of the annular conveying chain 210 is consistent with the length direction of the moving plate 120, and the conveying direction of the annular conveying chain 210 is arranged opposite to the feeding direction of the stepping mechanism 130. A push-out assembly 250 is provided on the outer side of the upper side of the annular conveying chain 210, which is used to push the support base 2 into the positioning seat 220 one by one, so that the annular conveying chain 210 can convey the support base 2 entering the positioning seat 220 to one end facing the moving plate 120 to prepare for welding.

[0041] like Figure 2-Figure 4 As shown, the welding part 300 includes a lifting and traversing frame 310, a mechanical arm 320, a second motor 330, a mounting plate 340, and a welding gun 350. The lifting and traversing frame 310 is arranged outside a group of support seats 110 and close to one end of the ring conveyor chain 210 facing a group of support seats 110. The mechanical arm 320 is vertically arranged at the lower end of the lifting and traversing frame 310 in the traversing direction. The mechanical arm 320 adopts a two-axis mechanical arm, and both of the two-axis mechanical arms adopt a retractable telescopic rod, so that the mechanical arm 320 can move along It can move up and down in the vertical direction and can be extended and retracted horizontally in the direction of the circular conveyor chain 210; a motor mounting seat is provided at the end of the robot arm 320, and the second motor 330 is horizontally mounted on the motor mounting seat, and the output end of the second motor 330 faces the circular conveyor chain 210, and the mounting plate 340 is vertically arranged at the output end of the second motor 330, and the welding gun 350 is vertically installed at the upper end of the mounting plate 340, and when the vertical bracket 1 is docked with the bracket base 2, it is used to weld the docking point between the vertical bracket 1 and the bracket base 2.

[0042] Specific usage process:

[0043] Place the bracket base 2 horizontally into the ejection assembly 250, and make the width direction of the bracket base 2 face the circular conveyor chain 210, start the circular conveyor chain 210, and make the positioning seat 220 move synchronously with the circular conveyor chain 210. When the positioning seat 220 moves to the front of the ejection assembly 250, pause the circular conveyor chain 210, so that the ejection assembly 250 pushes the bracket base 2 into the positioning seat 220. When the front end of the bracket base 2 in the moving direction abuts against the stopper 240, the ejection assembly 250 moves backward out of the positioning seat 220.

[0044] Start the endless conveyor chain 210 again, so that the endless conveyor chain 210 moves along Figure 1The counterclockwise rotation shown causes the circular conveyor chain 210 to convey the positioning seat 220 carrying the bracket base 2 to the end of the circular conveyor chain 210 facing the movable plate 120, and then the circular conveyor chain 210 is paused, and the stepping mechanism 130 is started to push the vertical bracket 1 to move in the direction of the circular conveyor chain 210. When the vertical bracket 1 moves past the material blocking member 140, the front end of the vertical bracket 1 in the moving direction is butted against the top surface of the bracket base 2, so that the pressing plate 114 presses the top surface of the horizontal part of the vertical bracket 1, so that the inner surface of the horizontal part of the vertical bracket 1 is in close contact with the top surface of the movable plate 120, thereby ensuring that the vertical bracket 1 remains horizontal. The lifting and traversing frame 310 is started to drive the welding end of the welding gun 350 to move to the lower end of the joint between the vertical bracket 1 and the bracket base 2, and the welding gun 350 is started. The mechanical arm 320 moves vertically upward. When the welding of the joint between the vertical bracket 1 and the vertical part of one side of the bracket base 2 is completed, the second motor 330 is started to drive the mounting plate 340 to rotate along the joint between the vertical part and the horizontal part of the vertical bracket 1 and the bracket base 2, so that the welding gun 350 is rotated to the upper side of the horizontal part of the vertical bracket 1, and the welding end of the welding gun 350 is moved along the vertical bracket. 1 and the cross section of the bracket base 2 rotate and transition to the cross section, start the lifting and traversing frame 310, so that it drives the welding gun 350 to move horizontally to the joint of the vertical part and the cross section of the other side of the vertical bracket 1 and the bracket base 2. When the welding of the cross section is completed, start the second motor 330 again, so that the welding end of the welding gun 350 rotates along the joint of the cross section of the vertical bracket 1 and the other end of the bracket base 2, and transition to the vertical part on the other side of the vertical bracket 1, so that the mechanical arm 320 moves vertically downward, so that the welding gun 350 completes the welding of the vertical part on the other side of the vertical bracket 1. Thus, the welding of the photovoltaic bracket is completed.

[0045] Preferably, in order to enable the welded bracket to be automatically discharged, the pressure plate 114 can be rotatably connected to the output end of the downward pressure cylinder 113. When welding is completed, the welding gun 350 is reset, and the pressure plate 114 is rotated to the outside of a group of support seats 110, so that the annular conveyor chain 210 can transport the welded bracket upward to the upper side of the annular conveyor chain 210, release the stopper 240, so that the stopper 240 cancels the limit on the bracket base 2, and then use the robot to take out the welded bracket.

[0046] Preferably, Figure 6 , Fig. 9As shown, in order to meet the needs of vertical brackets 1 of different widths, the movable plate 120 can be moved along the width direction of the corresponding support seat 110 in a group of support seats 110. Specifically, a vertical baffle 111 is vertically upwardly arranged on one side opposite to the group of support seats 110 to prevent the movable plate 120 from interfering with the stepping mechanism 130 when the moving distance is too large. Rectangular grooves 112 are arranged at intervals on the top surfaces of a group of support seats 110, and the rectangular grooves 112 penetrate the corresponding upper and lower surfaces of a group of support seats 110, and a U-shaped seat 122 is vertically arranged at the bottom of the movable plate 120, and a group of support seats 110 corresponds to a U-shaped seat 122, and the vertical parts of the U-shaped seat 122 are slidably matched with the corresponding rectangular grooves 112, and the horizontal part of the U-shaped seat 122 is located on the bottom surface of a group of support seats 110, and an adjusting cylinder 123 is arranged on the outer side surface of the horizontal part of the U-shaped seat 122, and a group of support seats 110 corresponds to an adjusting cylinder 123, and the adjusting cylinder 123 is installed on the outer side of the corresponding group of support seats 110.

[0047] Specifically, Figure 8 As shown, a connecting groove 124 connected to the slide groove 121 is provided on the outer side of the movable plate 120. The material blocking member 140 includes an inverted T-shaped material blocking plate 141, a slide plate 142, a spring 143 arranged in an array along the bottom of the slide plate 142, a guide plate 144, and a bolt 145. The slide plate 142 is slidably arranged in the slide groove 121, the lower end of the spring 143 is connected to the bottom of the slide groove 121, and the upper end of the spring 143 is connected to the lower end of the slide plate 142. The vertical part of the material blocking plate 141 is vertically upward, and the horizontal part of the material blocking plate 141 is located on the top surface of the slide plate 142. The outer side surface of the horizontal part of the material blocking plate 141 passes through the connecting groove 124 and is connected to a side of the guide plate 144 facing the movable plate 120, and the guide plate 144 is arranged on the outer side of the movable plate 120, and the vertical length of the guide plate 144 is greater than the width of the connecting groove 124. The bolts 145 penetrate through the outer side of the guide plate 144 and connect to the outer side surface of the slide plate 142, so that the baffle plate 141 is fixed on the slide plate 142. When it is necessary to weld vertical brackets 1 of different lengths, the bolts 145 can be loosened to move the baffle plate 141. When the distance between the surface of the baffle plate 141 facing one end of the movable plate 120 and the end of the movable plate 120 facing the circular conveyor chain 210 is consistent with the length of the vertical bracket 1, the bolts 145 are tightened to fix the baffle plate 141. Therefore, the guide plate 144 can not only guide the baffle plate 141 when the slide plate 142 moves up and down, but also limit the vertical parts on both sides of the vertical bracket 1 when the vertical bracket 1 is welded.

[0048] Specifically, Figure 5 As shown, a first inclined surface 146 is provided on a surface of the material blocking plate 141 opposite to the moving direction of the vertical bracket 1 , so that the vertical bracket 1 can better pass through the top surface of the material blocking plate 141 under the pushing action of the stepping mechanism 130 .

[0049] Specifically, Fig. 9 As shown, the stepping mechanism 130 includes a plurality of support plates 131, the support plate 131 is located between two adjacent vertical baffles 111, and the width of the support plate 131 is smaller than the inner wall width of the vertical bracket 1, and a vertical rod 132 is provided at the lower end of each support plate 131, and the lower end of each vertical rod 132 is connected to the top surface of the same cross bar 133, and connecting shafts 134 are respectively provided at both ends of the cross bar 133, and rotating rods 135 are symmetrically provided at both ends of the connecting shaft 134, one end of the rotating rod 135 is rotatably connected to one end of the transmission shaft, and the transmission shaft is passed through the top of the triangular seat 136, and a synchronous wheel 137 is provided at the other end of the transmission shaft, and the synchronous wheels 137 on one side of the two ends of the cross bar 133 are connected through a synchronous belt 138, and the synchronous wheel on the other side of one end of the cross bar 133 is connected to another synchronous belt 138, and the other synchronous belt 138 is connected to the output end of the first motor 139.

[0050] like Figure 4-Figure 6 As shown, a conveyor belt 150 is provided at the bottom of one end of the movable plate 120 away from the circular conveyor chain 210. By placing the opening of the vertical bracket 1 on the conveyor belt 150 with the opening facing downward, the vertical bracket 1 can be automatically conveyed to the movable plate 120. A second inclined surface 125 is provided at one end of the movable plate 120 facing the conveyor belt 150, so that the vertical bracket 1 conveyed by the conveyor belt 150 can automatically enter the movable plate 120, and the lower end of the second inclined surface 125 is connected to a bent plate 126, and the bent plate 126 is bent inwardly. When the center line of the vertical bracket 1 and the symmetry plane of the movable plates 120 on both sides are not in the same vertical plane, it can be guided by the bent plate 126.

[0051] Specifically, in order to keep the welding position close when the vertical bracket 1 and the bracket base 2 are welded, an avoidance hole 221 is provided in the middle of the positioning seat 220, and a linear cylinder 211 is horizontally provided at the end of the circular conveyor chain 210 facing the movable plate 120, and a top plate 212 is provided at the output end of the linear cylinder 211, and the top plate 212 faces one end of the movable plate 120, and the shape of the top plate 212 is adapted to the shape of the avoidance hole 221. When the positioning seat 220 carrying the bracket base 2 moves to the end of the circular conveyor chain 210 facing the movable plate 120, that is, when the bracket base 2 is in a vertical state, the top plate 212 is used to push the bottom surface of the bracket base 2 through the avoidance hole 221, so that the bracket base 2 remains close to the vertical bracket 1.

[0052] Specifically, in order to facilitate the top plate 212 to push the bracket base 2 toward the vertical bracket 1 along the horizontal direction, when the bracket base 2 moves toward the vertical bracket 1, the downward side of the bracket base 2 is supported by the adjustment plate 230 to prevent it from falling. A support ear 222 is provided at one end of the positioning seat 220, and the stopper 240 includes an inverted L-shaped rotating plate 241.
