Description

Technical Field

[0001] This invention relates to the field of copper welding machine technology, specifically to a copper welding machine with adaptive positioning function. Background Technology

[0002] During the copper sheet end-press welding process, multiple copper sheets need to be precisely positioned before being joined. Currently, most conventional copper welding machines use a robotic arm to load and position the copper sheets one by one. This requires high control precision and motion planning from the robotic arm, and it is difficult to simultaneously adapt to the clamping and positioning of copper sheets of different materials, such as hard and soft ones, thus limiting the processing applicability of the equipment.

[0003] Existing copper welding machines require multiple independent drive units to control the clamping and positioning, welding, material feeding and unloading, and port opening and closing processes. This results in a complex overall equipment structure, high manufacturing costs and control difficulties. The timing accuracy of each process is insufficient, which can easily lead to positioning deviations and make it difficult to ensure the quality and stability of copper sheet welding.

[0004] For example, Chinese patent (CN114498087A) discloses a copper busbar pressure welding device for new energy vehicles. Through the cooperation of rollers, internal threaded sleeves, springs and gasket grooves, gaskets are added to the gasket grooves according to the welding requirements of the copper busbars to help the copper busbars maintain the welding curve during welding. By turning the internal threaded sleeves, the rollers are driven to descend and press the two ends of the copper busbars together, so that the copper busbars are not prone to displacement during pressure welding, thus improving the welding quality of the copper busbars. After the pressure welding is completed, the user can directly pull out the copper busbars from the bottom of the rollers for easy material removal, which greatly improves the processing efficiency of copper busbars.

[0005] However, the aforementioned device is not equipped with a welding fume purification mechanism and requires manual operation by staff. Fume leakage is likely to occur in the surrounding environment, resulting in poor protection of the working environment and failing to meet the needs of staff. Summary of the Invention

It eliminates the need for multiple independent drive devices, resulting in a streamlined and compact structure. The precise timing of each process significantly reduces equipment costs and control complexity, enabling adaptive positioning and automated operation of copper sheet pressure welding. Furthermore, during the pressure welding process, the shroud and fixed cylinder are sealed tightly, simultaneously triggering the automatic start of the flue gas purifier. After pressure welding, the positive and negative electrodes remain in contact for a threshold time, allowing for sufficient absorption and purification of welding fumes, effectively improving the working environment. No manual assistance is required throughout the process, ensuring stable copper sheet pressure welding quality and meeting the needs of workers. Attached Figure Description

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Example 1

[0022] Please refer to Figures 1-13 As shown, a copper welding machine with adaptive positioning function includes a frame 1. A fixed cylinder 101 is welded inside the frame 1. A clamping mechanism 2 and a pushing mechanism 3 are provided inside the fixed cylinder 101. A platform 102 is fixedly installed at the top center of the fixed cylinder 101. A flue gas purifier 103 is provided on the top right side of the frame 1. The input end of the flue gas purifier 103 is connected to the inside of the fixed cylinder 101. A support plate 104 is also welded to the top rear side of the frame 1. A first driving mechanism 4 and a second driving mechanism 5 are provided on the support plate 104. A fixed plate 105 is welded to the bottom of the peripheral surface of the fixed cylinder 101. An opening and closing mechanism 6 is provided on the fixed plate 105. The opening and closing mechanism 6 is used to open or close the bottom opening of the fixed cylinder 101. The first driving mechanism 4 and the second driving mechanism 5 cooperate to control the operation of the clamping mechanism 2, the pushing mechanism 3 and the opening and closing mechanism 6, as well as to control the opening and closing of the flue gas purifier 103.

[0023] Example 2

[0024] Please refer to Figure 3 As shown, the clamping mechanism 2 includes a first lead screw 201 and a first guide rod 202. The first lead screw 201 is rotatably connected to the inside of the fixed cylinder 101, and the first guide rod 202 is fixedly connected to the inside of the fixed cylinder 101. The outer end of the first lead screw 201 extends to the outside of the fixed cylinder 101 and is fixedly mounted with a first rotating wheel 204. Two sets of L-shaped plates 203 are slidably connected to the outer wall of the first guide rod 202. The two sets of L-shaped plates 203 are respectively threaded to both ends of the outer wall of the first lead screw 201, and the threads at both ends of the first lead screw 201 are in opposite directions.

[0025] Please refer to Figure 3 and Figure 6As shown, the clamping mechanism 2 also includes a first support member 205 welded to the rear top of the frame 1. A first rotating shaft 206 is rotatably connected inside the top of the first support member 205. A second rotating wheel 207 and a first gear 208 are fixedly connected to both ends of the first rotating shaft 206, respectively. The second rotating wheel 207 is connected to the first rotating wheel 204 via a belt.

[0026] Those skilled in the art will understand that by driving the first gear 208 to rotate, the rotation of the first gear 208 causes the first shaft 206 and the second wheel 207 to rotate as a whole. The rotation of the second wheel 207, driven by the belt, causes the first wheel 204 to rotate. The rotation of the first wheel 204 causes the first lead screw 201 to rotate, thereby moving the two sets of L-shaped plates 203 closer together or further apart, with the bottom wall of the horizontal plate of the L-shaped plate 203 flush with the top wall of the platform 102. (The rotation of the first gear 208 will be explained in the following working principle.)

[0027] Example 3

[0028] Please refer to Figure 4 As shown, the pushing mechanism 3 includes a sleeve 301 fixedly connected to the right side inside the fixed cylinder 101. A second lead screw 302 is rotatably connected inside the sleeve 301. A movable plate 304 is threadedly connected to the outer wall of the second lead screw 302. The movable plate 304 is slidably connected to the second guide rod 303. The second guide rod 303 is fixedly connected to the inside of the sleeve 301. Two sets of first rods 305 are fixedly connected to the outer side of the movable plate 304. The other end of the first rod 305 extends to the outside of the sleeve 301 and is fixedly connected to the first mounting block 306. A push plate 307 is fixedly installed on the top of the first mounting block 306. A third rotating wheel 308 is fixedly connected to the outer end of the second lead screw 302.

[0029] Please refer to Figure 4 and Figure 5 As shown, the feeding mechanism 3 also includes a second support member 309 fixedly connected to the rear side of the top of the frame 1. A second rotating shaft 310 is rotatably connected inside the top of the second support member 309. A second gear 311 and a fourth rotating wheel 312 are fixedly connected to the outer wall of the second rotating shaft 310. The fourth rotating wheel 312 is also connected to the third rotating wheel 308 via a belt.

[0030] Those skilled in the art will understand that by driving the second gear 311 to rotate, the rotation of the second gear 311 causes the second rotating shaft 310 and the fourth rotating wheel 312 to rotate as a whole. The rotation of the fourth rotating wheel 312, driven by the belt, causes the third rotating wheel 308 to rotate. The rotation of the third rotating wheel 308 causes the second lead screw 302 to rotate, thereby causing the movable plate 304 to move to the left, which in turn causes the first mounting block 306 and the push plate 307 to move to the left as a whole. Conversely, if the second gear 311 rotates in the opposite direction, it causes the first mounting block 306 and the push plate 307 to move to the right until they return to their original positions. (The rotation of the second gear 311 is explained in the following working principle.)

[0031] Example 4

[0032] Please refer to Figure 8 As shown, the first drive mechanism 4 includes a linear drive rail 401 and a cylindrical cover 409. The linear drive rail 401 is fixedly connected to the left side of the support plate 104 and is used to drive the lifting plate 402 to move up and down. A first rack 403 is fixedly installed on the left side wall of the lifting plate 402. A second rod 404 is fixedly connected to the front side of the lifting plate 402. A pressing member 405 and a second mounting block 406 are fixedly installed at the bottom of the second rod 404. A high-temperature welding head 407 is fixedly connected to the bottom of the second mounting block 406. A third rod 410 is fixedly connected to both sides of the top of the cylindrical cover 409. The second mounting block 406 is slidably connected to the third rod 410.

[0033] Please refer to Figure 8 As shown, a first spring 408 is sleeved on the outside of the third rod body 410. The top of the first spring 408 is fixedly connected to the second mounting block 406, and the bottom of the first spring 408 is fixedly connected to the top wall of the cylindrical cover 409. A circular hole is opened through the middle of the top of the cylindrical cover 409, and the bottom of the high-temperature welding head 407 is opened through the circular hole and extends into the cylindrical cover 409.

[0034] Those skilled in the art will understand that by driving the linear drive rail 401 to work, the lifting plate 402 is driven to move downward, so that the first rack 403, the second rod 404, the pressing member 405, the second mounting block 406, the high-temperature welding head 407 and the cylinder cover 409 move downward as a whole. When the cylinder cover 409 moves downward to the point where the bottom of the cylinder cover 409 is in contact with the top of the fixed cylinder 101, the lifting plate 402 can still continue to move downward, and the high-temperature welding head 407 can still continue to move downward. Both sets of first springs 408 are in a contracted state. A sealing structure consisting of a sealing groove and a sealing gasket is provided between the bottom of the cylinder cover 409 and the top of the fixed cylinder 101. This is existing technology and will not be elaborated on here. Similarly, a sealing structure is also provided between the lifting plate 402 and the round hole at the top of the cylinder cover 409.

[0035] Example 5

[0036] Please refer to Figure 9 As shown, the second drive mechanism 5 includes a third support member 501 fixedly connected to the front side of the support plate 104. A through hole 505 is provided through the third support member 501. Two sets of second springs 502 are fixedly connected to the top of the third support member 501. The top of the second springs 502 is fixedly connected to the lifting member 503. The lifting member 503 is slidably connected to the fourth rod 504. The fourth rod 504 is fixedly installed on the front side of the support plate 104. A first connecting rod 506 is fixedly installed at the bottom of the lifting member 503. A third connecting rod 508 is fixedly connected to the bottom of the first connecting rod 506 through a second connecting rod 507. A positive electrode plate is provided on the circumferential surface of the second connecting rod 507.

[0037] Please refer to Figure 10 As shown, the second drive mechanism 5 also includes a fifth rod 509 fixedly connected to the front side of the support plate 104. A lifting block 510 is slidably connected to the fifth rod 509. A sixth rod 511 is slidably connected inside the lifting block 510. A first auxiliary block 512 is fixedly installed at the outer end of the sixth rod 511. A negative electrode plate is provided on the left side wall of the first auxiliary block 512. A third spring 513 is sleeved on the outside of the sixth rod 511. The two ends of the third spring 513 are fixedly connected to the first auxiliary block 512 and the lifting block 510, respectively. A cylinder is fixedly installed at the top of the lifting block 510. A second rack 514 is fixedly connected to the output end of the cylinder. A second auxiliary block 515 is fixedly connected to the bottom of the third support member 501.

[0038] Those skilled in the art will understand that when the pressing member 405 moves downward, it presses the lifting member 503 downward. Both sets of second springs 502 are in a contracted state, driving the first connecting rod 506, the second connecting rod 507, and the third connecting rod 508 to move downward as a whole. When the bottom of the third connecting rod 508 contacts the top inclined surface of the first auxiliary block 512, it drives the first auxiliary block 512 to move to the right, causing the third spring 513 to also be in a contracted state. In this way, the third connecting rod 508 can "bypass" the first auxiliary block 512 and be located below the first auxiliary block 512. The first connecting rod 506, the second connecting rod 507, and the third connecting rod 508 continue to move downward as a whole, causing the peripheral surface of the second connecting rod 507 to contact the left side wall of the first auxiliary block 512, realizing the contact between the positive electrode and the negative electrode, connecting the circuit, and enabling the flue gas purifier 103 to work. When the pressing member 405 moves upward without pressing the lifting member 503, the lifting member 503 moves upward under the action of the two sets of second springs 502 restoring their deformation. This causes the first connecting rod 506, the second connecting rod 507, and the third connecting rod 508 to move upward as a whole. The top of the third connecting rod 508 then supports the bottom of the first auxiliary block 512 and moves upward, causing the lifting block 510 to slide upward along the outer wall of the fifth rod 509. When the top inclined surface of the first auxiliary block 512 slides upward and contacts the bottom inclined surface of the second auxiliary block 515, it also drives the first auxiliary block 512 to move to the right. The third spring 513 is in a contracted state. In this way, the third connecting rod 508 can "bypass" the first auxiliary block 512 and be located above the first auxiliary block 512. Then, the bottom of the first auxiliary block 512 is no longer supported by the top of the third connecting rod 508, and the lifting block 510 moves downward to the reset state under the action of gravity, that is, moves to the bottom of the fifth rod 509.

[0039] Example 6

[0040] Please refer to Figure 11 and Figure 12 As shown, the opening and closing mechanism 6 includes several sets of short rods 601 welded to the bottom of the fixed plate 105. A rotating gear ring 603 is rotatably connected to the bottom of the fixed plate 105 via a bearing 602. Several sets of limiting grooves 604 are formed through the rotating gear ring 603. The short rods 601 are slidably connected within the limiting grooves 604. Several connecting strips 608 are rotatably connected to the outer side of the rotating gear ring 603. A through groove 606 is formed through the middle of the fixed plate 105. The size of the through groove 606 matches the size of the bottom opening of the fixed cylinder 101. Several cover plates 607 are rotatably connected to the fixed plate 105 via pins 605. The other end of the connecting strip 608 is rotatably connected to the cover plate 607. The fixed cylinder 101... A fourth support member 609 is fixedly installed on the outer wall of 01. A third rotating shaft 610 and a fourth rotating shaft 613 are rotatably connected to the fourth support member 609. The two ends of the third rotating shaft 610 are fixedly connected to the third gear 611 and the first bevel gear 612, respectively. The third gear 611 meshes with the rotating gear ring 603. A fifth rotating wheel 615 and a second bevel gear 614 are fixedly installed on the fourth rotating shaft 613. The second bevel gear 614 meshes with the first bevel gear 612. The top of the first support member 205 is also rotatably connected to a fifth rotating shaft 616. A sixth rotating wheel 617 and a fourth gear 618 are fixedly connected to the two ends of the fifth rotating shaft 616, respectively. The sixth rotating wheel 617 is connected to the fifth rotating wheel 615 via a belt.

[0041] Those skilled in the art will understand that by driving the fourth gear 618 to rotate, the rotation of the fourth gear 618 causes the fifth shaft 616 and the sixth wheel 617 to rotate as a whole. The rotation of the sixth wheel 617, driven by the belt, causes the fifth wheel 615 to rotate. The rotation of the fifth wheel 615 causes the fourth shaft 613 and the second bevel gear 614 to rotate as a whole. The rotation of the second bevel gear 614 causes the first bevel gear 612 to rotate. The rotation of the first bevel gear 612 causes the third shaft 610 and the third gear 611 to rotate as a whole. The rotation of the third gear 611 then causes the rotating gear ring 603 to rotate. All the connecting bars 608 continue to rotate, causing all the cover plates 607 to rotate, thereby opening the through slot 606, that is, opening the bottom opening of the fixed cylinder 101. Conversely, if the fourth gear 618 rotates in the opposite direction, it also causes all the cover plates 607 to rotate, thereby closing the bottom opening of the fixed cylinder 101. (The rotation of the fourth gear 618 is explained in the following working principle.)

[0042] It is worth mentioning in this invention that a PLC control unit is fixedly installed on the outer wall of the frame 1. The PLC control unit is electrically connected to the linear drive rail 401 of the first drive mechanism 4, the cylinder of the second drive mechanism 5, the flue gas purifier 103, the external feeding conveyor and the unloading conveyor. Contact-type limit switches are respectively set on the support plate 104 at the upper limit position of the lifting plate 402, the clamping completion station, the welding station and the material pushing trigger station. The signal output terminal of each limit switch is connected to the PLC control unit to collect the position signal of the lifting plate 402, so as to realize the timing coordination of the actions of each process of the whole machine and the automatic control of the whole process without the need for manual intervention.

[0043] The working principle of this device is as follows: S1. When pressure welding the ends of several copper sheets, since copper sheets have both hard and soft properties, if a robotic arm is used for loading, it is necessary to transfer each copper sheet sequentially to the top of the platform 102 and position it, which places high demands on the robotic arm. Therefore, this invention pre-forms "constraint sheets" by bending aluminum plates or other hard metal materials to constrain several copper sheets (e.g., Figure 13 As shown), a feeding conveyor is then arranged in front of the fixed cylinder 101. The feeding conveyor transports the entire copper sheet group to be welded to the top of the platform 102. A discharging conveyor is arranged at the bottom of the fixed cylinder 101. The discharging conveyor is used to transport the welded copper sheet group to the next process. The start and stop cycles of the feeding and discharging conveyors are uniformly coordinated and controlled by the PLC control unit, which precisely matches the cycle of the welding process to achieve fully automated connection of loading and unloading. This step is the preparatory work. S2. After a set of constrained copper sheets is conveyed to the top of the platform 102, in the initial state, the first rack 403 is located between the first gear 208 and the fourth gear 618, and the first rack 403 is not engaged with either the first gear 208 or the fourth gear 618. The PLC control unit outputs a drive signal to control the linear drive rail 401 to start. By driving the linear drive rail 401 to work, the lifting plate 402 moves downward, causing the first rack 403, the second rod 404, the pressing member 405, and the second mounting block to move downward. 406. The high-temperature welding head 407 and the sleeve 409 move downward as a whole. During the downward movement of the first rack 403, it meshes with the first gear 208 and drives the first gear 208 to rotate, which causes the two sets of L-shaped plates 203 to move closer to each other. The horizontal plates of the two sets of L-shaped plates 203 clamp the copper sheet group on the top of the platform 102 from left and right. When the lifting plate 402 moves down to the limit switch position corresponding to the clamping position, the limit switch feeds back the clamping signal to the PLC control unit, realizing adaptive positioning of the copper sheet group. S3. The first rack 403 moves to a position below the first gear 208, and then the lifting plate 402 continues to move downward, causing the cylinder cover 409 to move downward, so that the bottom of the cylinder cover 409 is in contact with the top of the fixed cylinder 101. The lifting plate 402 continues to move downward, and also causes the high-temperature welding head 407 to continue to move downward. Both sets of first springs 408 are in the contracted state. The pressing component 405 moves downward to begin pressing the lifting component 503 downward. Both sets of second springs 502 are in the contracted state, causing the first connecting rod 506, the second connecting rod 507, and the third connecting rod 508 to move downward as a whole. When the bottom of the third connecting rod 508 contacts the top inclined surface of the first auxiliary block 512, the first auxiliary block 512 is driven to move to the right, so that the third spring 513 is also in a contracted state. The third connecting rod 508 then "bypasses" the first auxiliary block 512 and is located below the first auxiliary block 512. Under the action of the third spring 513 restoring its deformation, the first auxiliary block 512 moves to the left. The left side of the first auxiliary block 512 begins to contact the peripheral surface of the second connecting rod 507, realizing the contact between the positive electrode and the negative electrode, connecting the circuit, and enabling the flue gas purifier 103 to work. S4. The lifting plate 402 continues to move downward, driving the high-temperature welding head 407 to continue moving downward. The bottom of the high-temperature welding head 407 performs pressure welding on the rear end of the copper sheet group, so that several copper sheets in the copper sheet group are connected together. During this process, the first auxiliary block 512 is always in contact with the peripheral surface of the second connecting rod 507. The flue gas purifier 103 is always in working condition, absorbing and purifying the smoke and dust generated during the pressure welding process. S5. After the pressure welding is completed, the lifting plate 402 moves upward and the pressing part 405 also moves upward without pressing the lifting part 503. Under the action of the two sets of second springs 502 restoring their deformation, the lifting part 503 moves upward, driving the first connecting rod 506, the second connecting rod 507 and the third connecting rod 508 to move upward as a whole. The top of the third connecting rod 508 then supports the bottom of the first auxiliary block 512 and moves upward, causing the lifting block 510 to slide upward along the outer wall of the fifth rod 509. During this process, the flue gas purifier 103 is still working, making the internal smoke and dust purification more thorough. S6. When the top inclined surface of the first auxiliary block 512 slides upward to contact the bottom inclined surface of the second auxiliary block 515, it also drives the first auxiliary block 512 to move to the right. The third spring 513 is in a contracted state, and the third connecting rod 508 "bypasses" the first auxiliary block 512 and is located above the first auxiliary block 512. The bottom of the first auxiliary block 512 is no longer supported by the top of the third connecting rod 508. Under the action of gravity, the lifting block 510 moves downward to the reset state. The lifting plate 402 continues to move upward, driving the first rack 403 to move upward. The first rack 403 meshes with the first gear 208 and drives the first gear 208 to rotate in the opposite direction. The two sets of L-shaped plates 203 move away from each other and release the clamping of the copper sheet group. S7. Next, the lifting plate 402 continues to move downwards, repeating the above operation, until the top of the third connecting rod 508 drags the bottom of the first auxiliary block 512 upwards. The cylinder output end drives the second rack 514 forward towards the second gear 311. During the upward movement of the first auxiliary block 512, the lifting block 510 moves upwards, and the second rack 514 moves upwards to start meshing with the second gear 311 and drive the second gear 311 to rotate. This causes the second lead screw 302 to rotate, thereby driving the movable plate 304 to move to the left. This causes the first mounting block 306 and the push plate 307 to move to the left as a whole, pushing the welded copper sheet assembly on the top of the platform 102 down to the bottom of the fixed cylinder 101. S8, the lifting plate 402 moves upward again until all components are reset. The lifting plate 402 moves upward again, and the first rack 403 continues to move upward, starting to mesh with the fourth gear 618 and drive it to rotate, so that all the connecting bars 608 keep rotating, driving all the cover plates 607 to rotate, thus opening the through slot 606, that is, opening the bottom opening of the fixed cylinder 101. The copper sheet group that has been pressure welded falls onto the bottom feeding conveyor. The PLC control unit synchronously controls the feeding conveyor to start, and transports the finished copper sheet group to the next process. Repeat the above steps to weld the next copper sheet group. The timing of all processes is automatically controlled by the PLC control unit in conjunction with the position signals of the limit switches. The whole process is fully automatic and requires no manual assistance, thus meeting the needs of the staff.
