[0002] As a necessary equipment in the basketball court, basketball is generally set up in the center of the two ends of the basketball court and is divided into many types, including hydraulic, mobile, fixed, hanging, petrel and cannon types, etc. However, no matter what kind of basketball stand, the manufacturing of its backboard is inseparable from the welding process.

[0003] In the prior art, a basketball stand is generally composed of a backboard, a basket frame and backboard pillars, wherein the backboard is generally made of multiple square tubes spliced ​​into a rectangle, then welded, and then an acrylic panel is installed to complete the assembly of the backboard.

[0004] In the prior art, when a square tube is welded by a robot arm, since the square tube to be welded is generally fixed on a work surface, the welding machine can generally only weld one side of the square tube. However, when the other side needs to be welded, the square tube needs to be removed from the work surface, turned over and then fixed before the other side can be welded, thereby increasing the work process and reducing production efficiency.

[0005] To this end, the present invention provides a basketball stand welding device. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figure 1 to Figure 2 As shown, a basketball stand welding device according to an embodiment of the present invention comprises a base 1; a pair of support columns 2 are slidably connected to the top surface of the base 1; the two support columns 2 are driven by a screw rod and a servo motor; a connecting frame 3 is fixedly connected to the top surface of the support column 2; a plurality of evenly arranged receiving plates 4 are fixedly connected to the top surface of the connecting frame 3; a baffle 5 is installed at one end of the top surface of the receiving plate 4 close to the center of the connecting frame 3; a hydraulic cylinder 6 is fixedly connected to the end of the top surface of the receiving plate 4 away from the baffle 5; a push plate 7 is fixedly connected to the telescopic end of the hydraulic cylinder 6; The top surface is fixedly connected with a guide rail 8; the guide rail 8 is annularly arranged, including a pair of horizontal guide rails 8 and a pair of semicircular guide rails 8, the two horizontal guide rails 8 are symmetrically arranged one above and one below, and the two semicircular guide rails 8 are respectively located on both sides of the horizontal guide rail 8 and are fixedly connected to the horizontal guide rail 8; the surface of the guide rail 8 is slidably connected with a welding mechanical arm 9, and the welding mechanical arm 9 is driven by a servo motor; when working, the backboard of the basketball stand is generally formed by splicing and welding two pairs of square tubes S, and in order to facilitate the welding between the square tubes S, the embodiment of the present invention can be used, first the user places the square tube S to be welded It is placed on the top surface of the receiving plate 4 and is located between the baffle plate 5 and the push plate 7. Then, the hydraulic cylinder 6 is started, and the push plate 7 is driven by the hydraulic cylinder 6 to press against the baffle plate 5, so that the square tube S to be welded is clamped between the baffle plate 5 and the push plate 7, thereby completing the fixation of the square tube S and splicing the welding ends of the square tubes S together. Subsequently, the welding robot arm 9 on the guide rail 8 can weld the splicing between the square tubes S. At the same time, the screw rod will also drive the support column 2, the connecting frame 3 and the square tube S to be welded to move together, thereby facilitating the splicing of the square tubes S by the welding machine robot arm When the top surface and the side surface joints of the square tube S are welded, the welding robot arm 9 will slide along the surface of the guide rail 8 until it slides to the bottom of the guide rail 8, and then the welding robot arm 9 can weld the joints on the bottom surface of the square tube S, thereby completing the welding of the entire backboard frame. The welding robot arm 9 slides along the surface of the guide rail 8 to complete the welding of the top and bottom of the square tube S, thereby avoiding the user from manually removing the square tube S and turning it over, thereby reducing the process of turning over the square tube S, thereby improving production efficiency.

[0023] like Figures 2 to 3As shown, the top surface of the receiving plate 4 is rotatably connected with a plurality of evenly arranged driving rollers 10 between the push plate 7 and the baffle 5; the driving rollers 10 are driven by a servo motor; the baffle 5 is L-shaped, and the top surface of the horizontal part of the baffle 5 is flush with the top surface of the driving rollers 10; during operation, when the user needs to place the square tube S, the user can first place one end of the square tube S on the driving roller 10 on the surface of the receiving plate 4, and then the driving roller 10 rotates to drive the square tube S to move on the receiving plate 4. After the driving roller 10 rotates for a period of time, the driving roller 10 stops rotating, so that the middle part of the square tube S stops between the push plate 7 and the baffle 5, thereby reducing the amplitude of the user's manual adjustment of the square tube S, thereby reducing the difficulty of the user fixing the square tube S.

[0024] like Figure 3 to Figure 4 As shown, the receiving plate 4 is slidably connected to a positioning plate 11 on one side of the driving roller 10 in the conveying direction; an electric push rod 12 is fixedly connected to the bottom surface of the receiving plate 4; the telescopic end of the electric push rod 12 is fixedly connected to the surface of the positioning plate 11; a pressure sensor 13 is installed on the surface of the positioning plate 11 close to the receiving plate 4; the pressure sensor 13 is used to control the extension of the electric push rod 12; when the user places the square tube S on the driving roller 10 during operation, the user needs to place one end of the square tube S against the surface of the pressure sensor 13 on the positioning plate 11 At this time, the pressure sensor 13 controls the extension of the electric push rod 12 on the bottom of the receiving plate 4 through an electrical signal, thereby driving the positioning plate 11 to descend, so that the positioning plate 11 no longer blocks the square tube S. At this time, the driving roller 10 can normally drive the square tube S to move. The end face of the square tube S is limited by the positioning plate 11, so that the square tubes S placed on the driving roller 10 are all in the same position. Therefore, when the driving roller 10 drives the square tube S to move for the same period of time, the middle part of the square tube S will be roughly between the push plate 7 and the baffle 5, thereby reducing the adjustment range of the user.

[0025] like Figures 3 to 5 As shown, the top surface of the receiving plate 4 is slidably connected with multiple pairs of limit rods 14 in the gaps between multiple driving rollers 10; the spacing between the limit rods 14 is adapted to the square tube S to be welded; the bottom surface of the limit rod 14 is fixedly connected with a connecting plate 15; the connecting plate 15 is fixedly connected to the surface of the positioning plate 11; during operation, when the positioning plate 11 can block the movement of the square tube S, the limit rod 14 is in a state of extending out of the top surface of the driving roller 10, thereby limiting the position of the square tube S to prevent the square tube S from tilting and causing the square tube S to get stuck during movement, thereby ensuring the normal movement of the square tube S, and when the electric push rod 12 lowers the positioning plate 11, the electric push rod 12 will also drive the connecting plate 15 and the limit rod 14 to descend, so that the two sides of the square tube S are no longer blocked, so that the push plate 7 can be normally squeezed to the surface of the square tube S.

[0026] like Figure 4As shown, a side surface of the positioning plate 11 close to the limiting rod 14 is fixedly connected with an extrusion block 16; the surface of the extrusion block 16 is inclined and adapted to the cross-section of the square tube S to be welded; the pressure sensor 13 is fixedly connected to the inclined surface of the extrusion block 16; during operation, when the user presses the end face of the square tube S to the positioning block, the end face of the square tube S will approach the extrusion block 16. Since the extrusion block 16 is inclined, the inclined surface at the end of the square tube S can fit the end face of the square tube S, thereby ensuring that the end face of the square tube S can be completely fitted to the pressure sensor 13 on the surface of the extrusion block 16. While avoiding the square tube S from tilting, the extrusion of the square tube S can also be detected more accurately.

[0027] like Figure 1 , Figure 2 and Figure 6 As shown, two pairs of guide grooves 17 are provided on the top surface of the base 1; the guide grooves 17 face the joints of the square tubes S to be welded; a support plate 18 is slidably connected in the guide grooves 17, and the support plate 18 is driven by a hydraulic rod; the top of the support plate 18 is slidably connected to a limit plate 19; the limit plate 19 is L-shaped and driven by a hydraulic rod; during operation, when the push plate 7 pushes the square tube S to the top surface of the horizontal part of the baffle 5, the connecting frame 3 is still located in the middle of the base 1, and at this time, the limit plate 19 on the top of the support plate 18 rises, and then the support plate 18 moves toward the joints between the square tubes S under the drive of the hydraulic rod, and at this time, the surface of the limit plate 19 will squeeze the square tube S, so that the joints between the square tubes S are aligned, thereby ensuring the flatness of the subsequent welding.

[0028] like Figure 2 and Figure 6 As shown, a rotating groove 20 is provided at the bending part of the limit plate 19; a grinding roller 21 is rotatably connected in the rotating groove 20; the grinding roller 21 is driven by a servo motor; during operation, after the joints between the square tubes S are welded, the support column 2 drives the connecting frame 3 and the square tube S thereon to move to the middle of the base 1, and then the support plate 18 drives the limit plate 19 to move toward the square tube S again, and at this time the grinding roller 21 in the rotating groove 20 rotates, and when both sides of the limit plate 19 contact the surface of the square tube S, the grinding roller 21 will also contact the joints on the outside of the square tube S, thereby completing the preliminary grinding of the joints on the outside of the square tube S, so as to avoid the subsequent users from being injured by the burrs at the joints on the outside of the square tube S when transporting the welded square tube S.

[0029] like Figure 2 , Figure 6 and Figure 7As shown, a metal column 22 is fixedly connected to the surface of one side of the support plate 18 close to the center of the connecting frame 3; the metal column 22 is made of a magnetizable metal material; an adsorption plate 23 is fixedly connected to the top surface of the base 1 at a position corresponding to the support plate 18; an electromagnet 24 is fixedly connected to the side of the adsorption surface close to the metal column 22 at a position corresponding to the metal column 22; during operation, when the support plate 18 drives the limiting plate 19 to move toward the square tube S, the electromagnet 24 on the surface of the adsorption column is started, thereby adsorbing the metal column 22 on the surface of the support plate 18, and then pulling the metal column 22 and the support plate 18 fixedly connected to the metal column 22 toward the adsorption column, thereby preventing the grinding roller 21 on the surface of the limiting plate 19 from bending the top of the support plate 18 due to the extrusion of the square tube S during the grinding of the square tube S, causing the support plate 18 to tilt backward, and then making the grinding roller 21 on the limiting plate 19 unable to fully contact the square tube S.

[0030] like Figure 6 to Figure 7 As shown, the electromagnet 24 is arranged in a columnar shape; a sleeve 25 is fixedly connected to the outer side of the electromagnet 24; the inner diameter of the sleeve 25 is consistent with the outer diameter of the metal column 22; when working, when the electromagnet 24 is started, the electromagnet 24 will absorb the metal column 22, and the sleeve 25 on the outer side of the electromagnet 24 will be sleeved on the surface of the metal column 22, thereby restricting the metal column 22 and the support plate 18 fixedly connected to the metal column 22, thereby reducing the shaking of the upper limit plate 19 of the support plate 18 when grinding the square tube S, thereby improving the grinding effect of the joint of the square tube S.

[0031] like Figures 3 to 5 As shown, a cover plate 26 is rotatably connected to the top of the baffle 5 surface near the push plate 7; a torsion spring is installed at the rotation connection between the cover plate 26 and the baffle 5; during operation, after the square tube S is welded, the user needs to control the hydraulic cylinder 6 so that it no longer pushes the push plate 7 to squeeze the square tube S. At this time, the user can lift the welded square tube S and make the square tube S squeeze the cover plate 26 on the baffle 5 to rotate it upward, and then the user can remove the welded square tube S. After the square tube S is taken out, the cover plate 26 is restored under the drive of the torsion spring, so that the user can continue welding, thereby facilitating the user's taking.

[0032] During operation, the backboard of the basketball stand is generally formed by splicing and welding two pairs of square tubes S. In order to facilitate the welding between the square tubes S, the embodiment of the present invention can be used. First, the user places the square tube S to be welded on the top surface of the receiving plate 4 and between the baffle plate 5 and the push plate 7. Then, the hydraulic cylinder 6 is started, and the push plate 7 is driven by the hydraulic cylinder 6 to press against the baffle plate 5, so that the square tube S to be welded is clamped between the baffle plate 5 and the push plate 7, thereby completing the fixation of the square tube S and splicing the welding ends of the square tubes S together. Subsequently, the welding robot arm 9 on the guide rail 8 can weld the splicing between the square tubes S. At the same time, the screw rod will also drive the support column 2, the connecting frame 3 and the support column 4 to weld the square tubes S. The square tube S to be welded moves together, thereby facilitating the welding machine robot arm to weld the joints of each square tube S. When the joints of the top surface and the side surface of the square tube S are welded, the welding robot arm 9 will slide along the surface of the guide rail 8 until it slides to the bottom of the guide rail 8. Then the welding robot arm 9 can weld the joints on the bottom surface of the square tube S, thereby completing the welding of the entire backboard frame. The welding robot arm 9 slides along the surface of the guide rail 8 to complete the welding of the top and bottom of the square tube S, thereby avoiding the user from manually removing the square tube S and turning it over, thereby reducing the process of turning over the square tube S, thereby improving production efficiency.

[0033] When the user needs to place the square tube S, the user can first place one end of the square tube S on the driving roller 10 on the surface of the receiving plate 4, and then the driving roller 10 rotates to drive the square tube S to move on the receiving plate 4. After the driving roller 10 rotates for a period of time, the driving roller 10 stops rotating, so that the middle part of the square tube S stops between the push plate 7 and the baffle 5, thereby reducing the amplitude of the user's manual adjustment of the square tube S, thereby reducing the difficulty of the user fixing the square tube S.

[0034] When the user places the square tube S on the driving roller 10, the user needs to place one end of the square tube S against the surface of the pressure sensor 13 on the positioning plate 11. Then the pressure sensor 13 controls the extension of the electric push rod 12 on the bottom of the receiving plate 4 through an electrical signal, thereby driving the positioning plate 11 to descend, so that the positioning plate 11 no longer blocks the square tube S. At this time, the driving roller 10 can normally drive the square tube S to move. The end face of the square tube S is limited by the positioning plate 11, so that the square tubes S placed on the driving roller 10 are all in the same position. Therefore, after the driving roller 10 drives the square tube S to move for the same period of time, the middle part of the square tube S will be roughly between the push plate 7 and the baffle 5, thereby reducing the adjustment range of the user.

[0035] When the positioning plate 11 is able to block the movement of the square tube S, the limiting rod 14 is in a state of extending out of the top surface of the driving roller 10, thereby limiting the position of the square tube S and preventing the square tube S from tilting and causing the square tube S to get stuck during movement, thereby ensuring the normal movement of the square tube S. When the electric push rod 12 lowers the positioning plate 11, the electric push rod 12 will also drive the connecting plate 15 and the limiting rod 14 to descend, so that the two sides of the square tube S are no longer blocked, so that the push plate 7 can be normally squeezed onto the surface of the square tube S.

[0036] When the user presses the end face of the square tube S toward the positioning block, the end face of the square tube S will approach the extrusion block 16. Since the extrusion block 16 is inclined, the inclined surface at the end of the square tube S can fit the end face of the square tube S, thereby ensuring that the end face of the square tube S can be completely fitted to the pressure sensor 13 on the surface of the extrusion block 16. While avoiding the square tube S from tilting, the extrusion of the square tube S can also be detected more accurately.

[0037] When the push plate 7 pushes the square tube S to the top surface of the horizontal part of the baffle 5, the connecting frame 3 is still located in the middle of the base 1. At this time, the limit plate 19 on the top of the support plate 18 rises, and then the support plate 18 moves toward the joint between the square tubes S under the drive of the hydraulic rod. At this time, the surface of the limit plate 19 will squeeze the square tube S, so that the joints between the square tubes S are aligned, thereby ensuring the flatness of the subsequent welding.

[0038] When the joints between the square tubes S are welded, the support column 2 drives the connecting frame 3 and the square tube S thereon to move to the middle of the base 1, and then the support plate 18 drives the limit plate 19 to move toward the square tube S again. At this time, the grinding roller 21 in the rotating groove 20 rotates. When both sides of the limit plate 19 contact the surface of the square tube S, the grinding roller 21 will also contact the joints on the outside of the square tube S, thereby completing the preliminary grinding of the joints on the outside of the square tube S, so as to avoid the subsequent users being injured by the burrs at the joints on the outside of the square tube S when transporting the welded square tube S.

[0039] When the support plate 18 drives the limit plate 19 to move toward the square tube S, the electromagnet 24 on the surface of the adsorption column is started, thereby adsorbing the metal column 22 on the surface of the support plate 18, and then pulling the metal column 22 and the support plate 18 fixedly connected to the metal column 22 toward the adsorption column, thereby preventing the grinding roller 21 on the surface of the limit plate 19 from bending the top of the support plate 18 due to the squeezing of the square tube S during the grinding of the square tube S, causing the support plate 18 to tilt backward, and thus making it impossible for the grinding roller 21 on the limit plate 19 to fully contact the square tube S.

[0040] When the electromagnet 24 is started, the electromagnet 24 will absorb the metal column 22. At this time, the sleeve 25 on the outside of the electromagnet 24 will be sleeved on the surface of the metal column 22, thereby restricting the metal column 22 and the support plate 18 fixedly connected to the metal column 22, thereby reducing the shaking of the upper limit plate 19 of the support plate 18 when grinding the square tube S, thereby improving the grinding effect of the joint of the square tube S.

[0041] After the square tube S is welded, the user needs to control the hydraulic cylinder 6 so that it no longer pushes the push plate 7 to squeeze the square tube S. At this time, the user can lift the welded square tube S and make the square tube S squeeze the cover plate 26 on the baffle 5 to rotate it upward. Then the user can remove the welded square tube S. After the square tube S is taken out, the cover plate 26 is restored under the drive of the torsion spring, so that the user can continue welding, thereby facilitating the user's taking.
