Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0034] The specific embodiments are given below.

[0035] Please refer to Figures 1 to 11As shown, the copper bar welding processing device provided by the embodiment of the present application comprises a rack 1, the top of the rack 1 is provided with a moving assembly; one side of the rack 1 is provided with a rotating assembly; the surface of the rack 1 is provided with a positioning assembly; the moving assembly comprises a radial moving module 12; the radial moving module 12 is fixedly installed on the top of the rack 1; a first air cylinder 13 is fixedly connected to the output end of the radial moving module 12; a first motor 14 is fixedly connected to the output end of the first air cylinder 13; a connecting frame 15 is fixedly connected to the output end of the first motor 14; the connecting frame 15 is provided with a welding assembly and a cooling assembly on both sides respectively; the welding assembly comprises a laser output head 16 fixedly installed on the surface of the connecting frame 15; the rotating assembly comprises a second motor 17; the second motor 17 is fixedly installed on one side of the rack 1; a first gear 18 is fixedly connected to the output end of the second motor 17; the first gear 18 and the rack 1 are in fixed connection; a second gear 19 is arranged on one side of the first gear 18; the second gear 19 and the first gear 18 are in meshing relationship, and the second gear 19 and the rack 1 are in rotary connection; a clamping assembly is arranged on the surface of the second gear 19; the clamping assembly comprises a second air cylinder 110; the second air cylinder 110 is fixedly installed on the surface of the second gear 19; a pair of support plates 115 are fixedly connected to the surface of the second gear 19; a copper bar 116 is arranged on the top of each of the pair of support plates 115; a pressing plate 111 is arranged on the top of each of the copper bars 116; a rack 112 is fixedly connected to one side of the pressing plate 111; the output end of the second air cylinder 110 and one of the pressing plates 111 are in fixed connection; a third gear 113, a fourth gear 114 and a fifth gear 1141 are sequentially and rotatably connected to the surface of the second gear 19; the third gear 113 and the rack 112 close to the second air cylinder 110 are in meshing relationship; the third gear 113 and the fourth gear 114 are in meshing relationship; a belt is sleeved between the fourth gear 114 and the fifth gear 1141; the fifth gear 1141 and the other rack 112 are in meshing relationship;

[0036] When working, a pair of copper bars 116 can be placed on the top of the support plate 115 through mechanical hand or manual loading mode. During the process, the positioning assembly can position the connection of the pair of copper bars 116, so that it can be in the working area of the welding assembly. Then the clamping assembly can be started, that is, the second cylinder 110 will start and push the pressing plate 111 at the bottom thereof to move towards the copper bars 116. The pressing plate 111 will extrude and clamp the top of the copper bars 116. During the process, the rack 112 on one side of the pressing plate 111 will mesh with the third gear 113 as the pressing plate 111 moves. The third gear 113 will rotate and mesh with the fourth gear 114. The fourth gear 114 will transmit power to the fifth gear 1141 through the belt to make the fifth gear 1141 rotate. At this time, the fifth gear 1141 will rotate in the opposite direction relative to the third gear 113. The fifth gear 1141 will mesh with the adjacent rack 112, so that the pressing plate 111 connected thereto will move together with the pressing plate 111 at the bottom of the second cylinder 110 and simultaneously extrude and clamp the copper bars 116. After the copper bars 116 are fixed, the moving assembly can be started to control the welding assembly to weld the copper bars 116. Specifically, the radial movement module 12 can be electrically started to drive the first cylinder 13 to move axially. The radial movement module 12 can be a linear slide or a linear motor, etc. The first cylinder 13 can control the first motor 14 and the welding assembly at the bottom thereof to move vertically until the laser output head 16 is above the copper bars 116 and starts to perform laser welding thereon. The specific principle of the laser output head 16 is a mature technology disclosed in the art, so it will not be described here. After one side of the copper bars 116 is welded by the laser output head 16, the first motor 14 can be started to drive the connecting frame 15 to rotate half a circle, so that the cooling assembly is above the copper bars 116 to cool the welded part. Then the moving assembly can be avoided, and the rotating assembly can be started, that is, the second motor 17 drives the first gear 18 to rotate. The first gear 18 will mesh with the second gear 19, so that the second gear 19 can rotate one circle under the meshing action. At this time, the other side of the copper bars 116 will face the welding assembly. Then the rotating assembly can be closed and the above steps can be repeated to complete the welding and cooling of both sides of the copper bars 116. It is worth mentioning that the above operation can be realized through PLC integrated control, which is also a mature technology in the art, so it will not be described here. By setting the rotating assembly, the copper bars 116 can be quickly turned over after one side is welded and the other side is welded, improving the continuity of the device when welding the copper bars 116 and optimizing the turning operation required when welding the copper bars 116, thereby improving the convenience of the device when welding the copper bars 116.

[0037] Please refer to Figures 3 to 5As shown, one side of the support plate 115 is provided with an extension plate 2; one side of the extension plate 2 is fixedly connected with a first clamping plate 22, and the surface of the first clamping plate 22 is symmetrically provided with a mounting groove; a pair of second clamping plates 23 are slidably connected to the inner wall of the support plate 115, and springs are installed between the second clamping plates 23 and the support plate 115; the mounting grooves on the surfaces of the second clamping plates 23 and the first clamping plate 22 are correspondingly arranged; a plurality of elastic ropes 24 are fixedly connected to the top of the extension plate 2; and the bottom of the second clamping plate 23 is provided with a control assembly.

[0038] When welding a copper bar 116 with a long length, that is, the required finished product is L-shaped or other shaped structures, the second clamping plate 23 of the support plate 115 can be controlled to be in a contracted state through the control assembly, then the first clamping plate 22 on one side of the extension plate 2 can be aligned with the support plate 115, the extension plate 2 is inserted into the inside of the support plate 115 to splice, then the control assembly is released, so that the second clamping plate 23 is clamped into the mounting groove on one side of the first clamping plate 22 under the action of the spring reset, to realize the rapid expansion of the end surface of the support plate 115, so that the free end of the long copper bar 116 can be clamped between the elastic rope 24 and the extension plate 2 by pulling the elastic rope 24 when the copper bar 116 is placed, to provide additional stability for welding and clamping the copper bar 116, and to reduce the extrusion deformation of the copper bar 116 due to the suspension of one side. Through the arrangement of the extension plate 2 and the first clamping plate 22, the first clamping plate 22 and the second clamping plate 23 are docked to add the extension plate 2 to the end of the support plate 115, thereby improving the stability of the free end of the long copper bar 116 during welding, and improving the stability of the device for clamping copper bars 116 of different sizes during welding.

[0039] Please refer to Figures 4 to 6 As shown, the control assembly comprises a pull rope 3; the pull rope 3 and the second clamping plate 23 are in a fixed connection; a through hole is formed in the bottom of the support plate 115 for the movement of the pull rope 3; a sleeve 32 is fixedly connected to the bottom of the support plate 115; a pull rod 33 is slidably connected to the inner wall of the sleeve 32, and a spring is installed between the pull rod 33 and the support plate 115; the outer walls of the pair of pull ropes 3 and the pull rod 33 at the bottom of the support plate 115 are in a fixed connection;

[0040] When it is necessary to expand the extension plate 2 on the support plate 115, the pull rod 33 can be pulled to pull the pair of pull ropes 3 respectively, and the pull rope 3 can pull the second clamping plate 23, so that the second clamping plate 23 slides into the inside of the support plate 115, at this time the extension plate 2 and the first clamping plate 22 can be aligned and inserted into the inside of the support plate 115, then the pull rod 33 can be released, so that the second clamping plate 23 and the first clamping plate 22 are docked and installed, and the pair of second clamping plates 23 can be operated synchronously by pulling the pull rod 33, thereby simplifying the steps of installing the extension plate 2 by the device and reducing the workload and burden required when installing the extension plate 2.

[0041] Please refer to Figure 6 As shown in the figure, the outer wall of the pull rod 33 is fixedly connected with a bright ring 4; the bright ring 4 is used to judge the moving stroke of the pull rod 33;

[0042] By setting the bright ring 4, when the extension plate 2 needs to be disassembled, the pull rod 33 can be pulled to control the second clamping plate 23. At this time, the worker can observe the exposure state of the bright ring 4. When the bright ring 4 is completely slid out of the sleeve 32, it means that the second clamping plate 23 is completely separated from the first clamping plate 22. At this time, the extension plate 2 together with the first clamping plate 22 can be taken out from the inside of the support plate 115, reducing the need for the worker to pull and test multiple times when disassembling the extension plate 2, and facilitating the disassembly of the extension plate 2.

[0043] Please refer to Figure 7 and Figure 8 As shown in the figure, the cooling assembly comprises a second connecting pipe 54; the bottom of the second connecting pipe 54 is threadedly connected with a crushing pipe 53; the inner wall of the crushing pipe 53 is provided with a cutting assembly; the bottom of the crushing pipe 53 is threadedly connected with a first connecting pipe 5; the bottom of the first connecting pipe 5 is threadedly connected with a throat pipe 52; the surface of the throat pipe 52 is provided with a variable diameter;

[0044] When the copper bar 116 welding position needs to be cooled, the end of the second connecting pipe 54 is sequentially connected with a dry ice particle storage tank and a high-pressure gas pump through a hose. The high-pressure gas pump sends the dry ice particles to the output port of the second connecting pipe 54 and the throat pipe 52 through the high-pressure gas flow. The above dry ice cooling principle has been disclosed in CN114147391B, so it will not be repeated here. Due to the variable diameter of the throat pipe 52, the gas flow is accelerated under the action of the cross-section reduction, so that the high-speed cooling gas flow carrying the dry ice particles can reach the surface of the copper bar 116. The dry ice particles ejected by the gas flow collide at high speed at the welding position, and the copper bar 116 is quickly cooled due to the sublimation heat absorption of the dry ice particles.

[0045] Please refer to Figure 9 As shown in the figure, the cutting assembly comprises a connecting seat 6; the inner walls of the connecting seat 6 and the crushing pipe 53 are fixedly connected; one side of the connecting seat 6 is rotatably connected with a turbine 62; one side of the turbine 62 is fixedly connected with a rotating shaft 63; the surface of the rotating shaft 63 is fixedly connected with a plurality of first blades 64;

[0046] When the gas flow passes through the second connecting pipe 54, the inclined blades on the surface of the turbine 62 will rotate under the power of the gas flow, so that the rotating shaft 63 will rotate with the turbine 62, and the first blades 64 will also rotate with the turbine 62. When the first blades 64 rotate, they will crush the dry ice particles passing through the second connecting pipe 54, thereby reducing the particle size and reducing the possibility of blockage at the variable diameter of the throat pipe 52.

[0047] Please refer to Figure 9 As shown in the figure, the first blade 64 is fixedly connected with a plurality of second blades 7; the end of the second blade 7 is pointedly arranged;

[0048] By arranging a plurality of second blades 7, when the first blade 64 performs transverse crushing on the dry ice particles, the second blades 7 can also perform vertical crushing on the particles, thereby assisting the first blade 64 in crushing the dry ice particles, and ensuring that the throat pipe 52 can stably transport the mixed gas.

[0049] Please refer to Figure 10 As shown in the figure, the bottom of the throat pipe 52 is fixedly connected with a fixing frame 8; the outer wall of the fixing frame 8 is fixedly connected with a plurality of guide plates 82, and the guide plates 82 are arc-shaped arranged;

[0050] By arranging the guide plates 82, since one end of the guide plates 82 faces the outlet of the throat pipe 52 and the other end extends outward, part of the cooling gas flow sprayed out of the outlet of the throat pipe 52 can be diffused to the surrounding under the guiding action of the guide plates 82, and the other part of the gas flow can directly pass through the holes in the fixing frame 8, thereby realizing the flow guiding effect of the device on the sprayed gas flow, expanding the contact area between the cooling gas flow and the copper bar 116, and improving the cooling effect.

[0051] Please refer to Figure 10 As shown in the figure, the variable-diameter position of the inner wall of the throat pipe 52 is fixedly connected with an elastic heat preservation cloth 9; the inside of the elastic heat preservation cloth 9 is filled with an elastic support body;

[0052] By arranging the elastic heat preservation cloth 9, when the cooling gas flow passes through the elastic heat preservation cloth 9, the cooling gas flow with the dry ice particles can exert different degrees of extrusion on the elastic heat preservation cloth 9 and the elastic support body inside the elastic heat preservation cloth 9, and the elastic heat preservation cloth 9 and the elastic support body can ensure the arc curvature of the variable-diameter position of the elastic heat preservation cloth 9, form a dynamic flow guiding surface, so that the dry ice particles can smoothly transition when passing through the variable-diameter position, thereby reducing the blocking situation at the variable-diameter position in the throat pipe 52, and in addition, the elastic heat preservation cloth 9 is provided with a heat preservation layer, which can heat preservation and protect the internal elastic support body, ensure its elastic stability, and it is worth mentioning that the elastic support body should be made of cold-resistant material to adapt to the low-temperature environment of dry ice.

[0053] Please refer to Figure 11 As shown in the figure, the positioning assembly comprises a laser leveling instrument 10; the laser leveling instrument 10 is fixedly installed on the surface of the rack 1;

[0054] By arranging the laser leveling instrument 10, before placing the copper bar 116, the laser leveling instrument 10 can be started to emit a vertical laser beam corresponding to the working range of the welding assembly, so that the copper bar 116 can be accurately placed during manual feeding, so that the welding position can correspond to the welding assembly.

[0055] Working principle: a pair of copper bars 116 can be placed on the top of the support plate 115 by mechanical hand or manual feeding method, the connecting part of the copper bars 116 can be positioned by the positioning assembly during the process, so that it can be in the working area of the welding assembly, then the clamping assembly can be started, that is, the second cylinder 110 will start and push the bottom pressing plate 111 towards the copper bars 116, the pressing plate 111 will extrude and clamp the top of the copper bars 116, during which the rack 112 on one side of the pressing plate 111 will mesh with the third gear 113 as the pressing plate 111 moves, the third gear 113 will rotate and mesh with the fourth gear 114, the fourth gear 114 will transmit power to the fifth gear 1141 through the belt to make the fifth gear 1141 rotate, at this time the fifth gear 1141 will rotate in the opposite direction relative to the third gear 113, the fifth gear 1141 will mesh with the adjacent rack 112, so that the pressing plate 111 connected thereto will move together with the pressing plate 111 at the bottom of the second cylinder 110 and simultaneously extrude and clamp the copper bars 116, after the copper bars 116 are fixed, the moving assembly can be started to control the welding assembly to weld the copper bars 116, specifically, the radial movement module 12 can be electrically started to drive the first cylinder 13 to move axially, the radial movement module 12 can be a linear slide or a linear motor, the first cylinder 13 can control the first motor 14 and the welding assembly at the bottom to move vertically until the laser output head 16 is above the copper bars 116 and starts to laser weld, the specific principle of the laser output head 16 is a mature technology disclosed in the art, so it is not repeated here, after one side of the copper bars 116 is welded by the laser output head 16, the first motor 14 can be started to drive the connecting frame 15 to rotate half a circle, so that the cooling assembly is above the copper bars 116 to cool the welded part, then the moving assembly can be avoided, and the rotating assembly can be started, that is, the second motor 17 drives the first gear 18 to rotate, the first gear 18 meshes with the second gear 19, so that the second gear 19 can rotate one revolution under the meshing action, at this time the other side of the copper bars 116 will face the welding assembly, then the rotating assembly can be closed and the above steps can be repeated to complete the welding and cooling of both sides of the copper bars 116, it is worth mentioning that the above operation can be realized by PLC integrated control, which is also a mature technology in the art, so it is not repeated here.When welding a long copper bar 116, that is, the desired finished product is an L-shaped or other shaped structure, the control assembly can be used to control the second clamping plate 23 of the support plate 115 in which it is located to be in a retracted state. Then, the first clamping plate 22 on one side of the extension plate 2 is aligned with the support plate 115, and the extension plate 2 is inserted into the support plate 115 to splice it. Then, the control assembly can be released, and the second clamping plate 23 is clamped into the mounting groove on one side of the first clamping plate 22 under the action of spring return, to quickly expand the end face of the support plate 115. When placing the long copper bar 116, its free end can be clamped between the elastic cord 24 and the extension plate 2 by pulling the elastic cord 24, providing additional stability for welding and clamping the copper bar 116, and reducing the extrusion deformation of the copper bar 116 due to one side hanging. When it is necessary to expand the extension plate 2 on the support plate 115, the pull rod 33 can be pulled to pull one pair of pull ropes 3, which in turn pull the second clamping plate 23, so that the second clamping plate 23 slides into the support plate 115. At this time, the extension plate 2 and the first clamping plate 22 can be aligned and inserted into the support plate 115, and then the pull rod 33 can be released to connect the second clamping plate 23 and the first clamping plate 22. By pulling the pull rod 33, one pair of second clamping plates 23 can be operated synchronously, simplifying the steps of installing the extension plate 2 and reducing the workload and burden required when installing the extension plate 2. By setting the bright color ring 4, when it is necessary to remove the extension plate 2, the pull rod 33 can be pulled to control the second clamping plate 23. At this time, the worker can observe the exposure state of the bright color ring 4. When the bright color ring 4 is completely slid out of the sleeve 32, it means that the second clamping plate 23 is completely separated from the first clamping plate 22. At this time, the extension plate 2 together with the first clamping plate 22 can be taken out of the support plate 115, reducing the need for the worker to pull and test multiple times when disassembling the extension plate 2, and facilitating the disassembly of the extension plate 2. When it is necessary to cool the welding position of the copper bar 116, the second connecting pipe 54 can be sequentially connected with a dry ice particle storage tank and a high-pressure gas pump through a hose. The high-pressure gas pump sends dry ice particles to the output port of the second connecting pipe 54 and the throat pipe 52 through high-pressure gas flow. The above dry ice cooling principle has been disclosed in CN114147391B, so it will not be repeated here. Because the throat pipe 52 is tapered, the airflow is accelerated under the action of the cross-section reduction, and the high-speed cooling airflow carrying dry ice particles can reach the surface of the copper bar 116. The dry ice particles ejected with the airflow collide at high speed at the welding position, and the copper bar 116 is quickly cooled due to the sublimation and heat absorption of the dry ice particles.When the airflow passes through the second connecting pipe 54, the inclined blades on the surface of the turbine 62 will rotate under the power of the airflow, so that the rotating shaft 63 will rotate with the turbine 62, and the first blade 64 will also rotate with the turbine 62. When the first blade 64 rotates, it will crush the dry ice particles passing through the second connecting pipe 54, thereby reducing the particle size and reducing the possibility of blockage at the throat pipe 52. By arranging multiple second blades 7, when the first blade 64 crushes the dry ice particles horizontally, the second blades 7 can also crush the particles vertically, thereby assisting the crushing effect of the first blade 64 on the dry ice particles, ensuring that the throat pipe 52 can stably transport the mixed gas. By arranging the guide plate 82, since one end of the guide plate 82 faces the outlet of the throat pipe 52 and the other end extends outward, part of the cooling airflow sprayed from the outlet of the throat pipe 52 will spread around under the guiding action of the guide plate 82, and the other part of the airflow can directly pass through the hole in the fixed frame 8, realizing the guiding effect of the device on the sprayed airflow, expanding the contact area between the cooling airflow and the copper bar 116, and improving the cooling effect. By arranging the elastic insulation cloth 9, when the cooling airflow passes through the elastic insulation cloth 9, it will exert different degrees of extrusion on the elastic insulation cloth 9 and the elastic support inside the elastic insulation cloth 9, and the elastic insulation cloth 9 and the elastic support can ensure the arc curvature of the elastic insulation cloth 9 at the variable diameter, forming a dynamic flow guide surface, so that the dry ice particles can smoothly transition when passing through the variable diameter, thereby reducing the blockage at the variable diameter in the throat pipe 52. In addition, the elastic insulation cloth 9 is provided with a heat preservation layer, which can protect the elastic support inside from heat and ensure its elasticity. It is worth mentioning that the elastic support should be made of cold-resistant material to adapt to the low-temperature environment of dry ice. By arranging the laser leveling instrument 10, before placing the copper bar 116, the laser leveling instrument 10 can be started to emit a vertical laser beam corresponding to the working range of the welding assembly, so that the copper bar 116 can be accurately placed during manual feeding, so that the welding position can correspond to the welding assembly.
