It is mainly used in the production and manufacturing of liquid-cooled plates for power batteries in new energy vehicles. Its core advantages include high efficiency, precision, and high degree of automation, and it can solve problems such as porosity, cracks, and deformation in traditional welding processes.

[0003] Chinese patent application No. 202110164921.1 discloses a laser welding device, including a mounting frame, a sliding frame, a welding head, and a fixing mechanism. The sliding frame is slidably mounted on the upper end of the mounting frame. The sliding frame is rectangular, and the welding head is slidably connected to the lower surface of the middle part of the sliding frame. A fixing mechanism is provided below the welding head. The fixing mechanism is fixedly mounted on the upper surface of the mounting frame. However, in actual use, when using a liquid cooling plate, the device is placed directly on the top of the worktable, which causes the liquid cooling plate to shift during welding, affecting the welding quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the movement of the liquid cooling plate during welding affects the welding effect, and to propose a high-precision laser intelligent welding system and method for liquid cooling plates in new energy vehicles.

[0006] A support frame, the top of which is connected to multiple support tooth plates, and one side of the support frame is connected to one side of the transmission mechanism, and a baffle is connected to one side of the top of the support frame;

[0007] The support frame is equipped with a fixing device, which includes an electric push rod. The push rod is connected to a connecting plate, and the top of the connecting plate is connected to an adjusting plate. The adjusting plate has multiple transmission grooves, and transmission blocks are located in the transmission grooves. A rotating rod is driven on one side of the transmission block. Multiple support boxes are connected to the outer wall of the rotating rod, and a fixing block is located in each support box.

The other end of the fixing rod is connected to one side of the inner wall of the support box, and the first spring is sleeved on the outside of the fixing rod.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the support frame is equipped with a cleaning device, which includes a motor, a first mounting box, and a second mounting box. A threaded seat is slidably connected to the inner wall of the second mounting box, and a threaded rod is threadedly connected to the threaded seat. A second connecting block is connected to the bottom of the threaded seat, and a connecting plate is connected to one side of the second connecting block. Two support plates are connected to the bottom of the connecting plate. A sliding groove is opened in the support plate, and a support block is slidably connected in the sliding groove. A support groove is opened on the top of the support block, and a support rod is slidably connected in the support groove. A second spring is sleeved on the outer wall of the support rod, and the top of the support rod is connected to the top of the inner wall of the sliding groove. The two ends of the second spring are respectively connected to one side of the sliding groove and the top of the support block. The bottom of the two support blocks is connected to the same cleaning plate.

[0014] As a further description of the above technical solution:

[0015] The second mounting box is installed on the inner wall of the support frame, and the motor side is fixedly installed on the support frame side. The motor output shaft extends into the second mounting box and is connected to one end of the threaded rod. A collection plate is connected to the inner wall of the support frame, and the top of the collection plate is in contact with the bottom of the cleaning plate.

[0016] As a further description of the above technical solution:

[0017] The connecting plate is connected to a first connecting block on the side away from the threaded seat. A sliding sleeve seat is connected to the top of the first connecting block. A long sliding rod is slidably connected inside the sliding sleeve seat. The two ends of the long sliding rod are respectively connected to one side of the inner wall of the first mounting box, and the first mounting box is installed on one side of the inner wall of the support frame.

[0018] As a further description of the above technical solution:

[0019] The top of the connecting plate is connected to multiple striking devices. Each striking device includes two fixed plates. The bottom of the fixed plates is connected to the top of the connecting plate, and each of the two fixed plates has a movable groove. Movable blocks are slidably connected in the movable grooves, and the two movable blocks are directly connected to the same stroke rod.

[0020] As a further description of the above technical solution:

[0021] The striking device also includes a striking plate, which has a travel groove, and the inner wall of the travel groove is slidably connected to the outer wall of the travel rod.

[0022] As a further description of the above technical solution:

[0023] The movable block is fitted with a sliding sleeve, and a short sliding rod is slidably connected inside the sliding sleeve. Two third springs are fitted on the outer wall of the short sliding rod, and the two ends of the third springs are respectively connected to one side of the inner wall of the movable groove and one side of the movable block.

[0024] A high-precision laser welding method for liquid-cooled plates in new energy vehicles specifically includes the following steps:

[0025] The electric push rod drives the connecting plate to move, which in turn drives the adjusting plate to move. This causes the adjusting plate to drive the transmission block to move via the transmission groove, which in turn drives the transmission rod to move. The transmission rod then drives the rotating rod to rotate via the fixed sleeve, which in turn drives the fixed block located outside the liquid cooling plate to rotate via the support box. This causes the outer fixed block to contact one side of the liquid cooling plate, thus pressing the liquid cooling plate and cooperating with the baffle to fix the liquid cooling plate in place. This ensures that the liquid cooling plate will not shift during welding, thus preventing it from affecting the welding effect.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, by setting a fixing device, the connecting plate is moved by an electric push rod, which in turn moves the adjusting plate. The adjusting plate then moves the transmission block through the transmission groove, which in turn moves the transmission rod. The transmission rod then moves the rotating rod through the fixing sleeve, which in turn moves the fixing block located outside the liquid cooling plate through the support box. This causes the outer fixing block to contact one side of the liquid cooling plate, thereby pressing the liquid cooling plate and fixing it in conjunction with the baffle. This ensures that the liquid cooling plate will not shift during welding, thus preventing it from affecting the welding effect.

[0028] 2. In this invention, a cleaning device is set up, and a motor drives the threaded rod to rotate, so that the threaded rod drives the second connecting block to move through the threaded seat. The second connecting block drives the connecting plate to move, and the connecting plate drives the bottom support plate to move, so that the support plate drives the cleaning plate to move through the support block. This allows the cleaning plate to clean the waste on the top of the collection plate, thereby facilitating the collection of waste and making it easier to recycle the waste.

[0029] 3. In this invention, by setting up a striking device, the connecting plate drives the fixed plate to move, which in turn drives the striking plate to move, causing the striking plate to contact the supporting toothed plate. This causes the striking plate to be forced to move to one side, which in turn causes the striking plate to drive the stroke rod to move through the stroke groove. The stroke rod then compresses and stretches the third spring through the movable block, causing the third spring to generate a rebound force. When the striking plate is misaligned with the supporting toothed plate, the striking plate moves in the opposite direction due to the rebound of the third spring, causing the striking plate to strike the next supporting toothed plate. This causes the supporting toothed plate to vibrate and shake off the attached waste debris, thereby preventing the waste debris from adhering to the surface of the supporting toothed plate and damaging the next liquid cooling plate, thus affecting the subsequent welding quality.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-9 This invention provides a technical solution: a high-precision laser welding system for liquid-cooled plates in new energy vehicles, comprising a transmission mechanism 1, a linear module 3 connected to the moving part of the transmission mechanism 1, a welding machine module 4 connected to the moving part of the linear module 3, and further comprising:

[0043] Support frame 2, with multiple support toothed plates 5 connected to the top of support frame 2, and one side of support frame 2 connected to one side of transmission mechanism 1, and a baffle connected to the top side of support frame 2;

[0044] The support frame 2 is equipped with a fixing device 6, which includes an electric push rod 605. The top of the electric push rod 605 is connected to a connecting plate 604. The top of the connecting plate 604 is connected to an adjusting plate 603. The adjusting plate 603 has multiple transmission grooves 613, and a transmission block 612 is located in each of the transmission grooves 613. A rotating rod 601 is driven to one side of the transmission block 612. Multiple support boxes 609 are connected to the outer wall of the rotating rod 601. A fixing block 606 is located in each support box 609. The electric push rod 605 drives the rotating rod 601 to rotate, so that the rotating rod 601 drives the fixing block 606 to fix the liquid cooling plate through the support box 609. One side of the electric push rod 605 is fixedly installed on one side of the support frame 2, and the transmission rod is connected to one side of the transmission block 612. 611, a fixed sleeve 602 is connected to the top of the transmission rod 611. The inner wall of the fixed sleeve 602 is connected to the outer wall of the rotating rod 601. One end of the rotating rod 601 extends into the support frame 2. One side of the inner wall of the rotating rod 601 is rotatably connected to one end of the rotating rod 601. A limit plate 614 is connected to one side of the transmission block 612. Two allowance grooves 607 are opened on one side of the fixed block 606. A first spring 610 is connected in the allowance groove 607. The other end of the first spring 610 is connected to one side of the inner wall of the support box 609. A fixed groove is opened on one side of the inner wall of the allowance groove 607. A fixed rod 608 is slidably connected in the fixed groove. The other end of the fixed rod 608 is connected to one side of the inner wall of the support box 609. The first spring 610 is sleeved on the outside of the fixed rod 608.

[0045] The specific implementation method is as follows: By setting a fixing device 6, the electric push rod 605 drives the connecting plate 604 to move, which in turn drives the adjusting plate 603 to move to one side. This causes the adjusting plate 603 to drive the transmission groove 613 to move, which in turn drives the transmission block 612 to move. This causes the transmission block 612 to drive the transmission rod 611 to move, which in turn drives the fixing sleeve 602 to rotate. The fixing sleeve 602 drives the rotating rod 601 to rotate, which in turn drives the support box 609 to rotate. When the support box 609 rotates, it drives the fixing block 606 to rotate, which causes the fixing block 606 on the outside of the liquid cooling plate to contact one side of the liquid cooling plate. Then, by continuously moving the fixing block 606, the fixing block 606 presses the liquid cooling plate, which in turn cooperates with the baffle to fix the liquid cooling plate, thereby ensuring that the liquid cooling plate will not be displaced during welding and affect the welding effect. The support module is provided with a transmission thread and a lead screw seat. This technology is existing technology and does not need to be described in detail.

[0046] The inner wall of the support frame 2 is equipped with a cleaning device 7, which includes a motor 710, a first mounting box 701, and a second mounting box 706. A threaded seat 709 is slidably connected to the inner wall of the second mounting box 706. A threaded rod 711 is threadedly connected to the inner wall of the threaded seat 709. A second connecting block 707 is connected to the bottom of the threaded seat 709. A connecting plate 705 is connected to one side of the second connecting block 707. Two support plates 712 are connected to the bottom of the connecting plate 705. A sliding groove is opened in the support plate 712, and a support block 715 is slidably connected in the sliding groove. A support groove is opened on the top of the support block 715, and a support rod 713 is slidably connected in the support groove. A second spring 714 is sleeved on the outer wall of the support rod 713, and the top of the support rod 713 is connected to the top of the inner wall of the sliding groove. The two ends of the second spring 714 are respectively connected to... The first mounting plate 705 is connected to the sliding groove on one side and the top of the support block 715, and the bottom of the two support blocks 715 are connected to the same cleaning plate 708. The second mounting box 706 is installed on the inner wall of the support frame 2, and the motor 710 is fixedly installed on one side of the support frame 2. The output shaft of the motor 710 extends into the second mounting box 706 and is connected to one end of the threaded rod 711. The inner wall of the support frame 2 is connected to a collection plate, and the top of the collection plate is in contact with the bottom of the cleaning plate 708. The side of the connecting plate 705 away from the threaded seat 709 is connected to the first connecting block 704. The top of the first connecting block 704 is connected to the sliding sleeve seat 703. The sliding sleeve seat 703 is slidably connected to the long sliding rod 702. The two ends of the long sliding rod 702 are respectively connected to one side of the inner wall of the first mounting box 701, and the first mounting box 701 is installed on one side of the inner wall of the support frame 2.

[0047] The specific implementation method is as follows: By setting up a cleaning device 7, the output shaft of the motor 710 drives the threaded rod 711 to rotate, causing the threaded rod 711 to move the threaded seat 709, the threaded seat 709 to move the second connecting block 707, the second connecting block 707 to move the connecting plate 705, the connecting plate 705 to move the bottom support plate 712, the support plate 712 to move the support block 715, and the support block 715 to move the cleaning plate 708. This allows the cleaning plate 708 to clean the waste debris on the top of the collecting plate, facilitating waste debris collection. The second spring 714, through its rebound force during installation, allows the second spring 714 to... The movable support block 715 moves downward, causing the bottom of the sweeping plate 708 to fit tightly against the top of the collection plate, thus ensuring the cleaning effect of the sweeping plate 708. The second spring 714 is supported by the support rod 713, causing the second spring 714 to bend when compressed, affecting the rebound effect of the second spring 714. The first connecting block 704 is moved by the other side of the connecting plate 705, causing the first connecting block 704 to drive the sliding sleeve seat 703 to slide on the outer wall of the long sliding rod 702. The sliding sleeve seat 703 supports the connecting plate 705 through the first connecting block 704, thus ensuring that the connecting plate 705 does not shift during movement, affecting the cleaning effect.

[0048] The top of the connecting plate 705 is connected to multiple striking devices 8. Each striking device 8 includes two fixed plates 803. The bottom of the fixed plates 803 is connected to the top of the connecting plate 705. Each of the two fixed plates 803 has a movable groove 807. A movable block 806 is slidably connected in the movable groove 807. The two movable blocks 806 are directly connected to the same stroke rod 808. The striking device 8 also includes a striking plate 801. A stroke groove 802 is provided in the striking plate 801. The inner wall of the stroke groove 802 is slidably connected to the outer wall of the stroke rod 808. A sliding sleeve is embedded in the movable block 806. A short sliding rod 804 is slidably connected in the sliding sleeve. Two third springs 805 are sleeved on the outer wall of the short sliding rod 804. The two ends of the third springs 805 are respectively connected to one side of the inner wall of the movable groove 807 and one side of the movable block 806.

[0049] The specific implementation method is as follows: By setting up a striking device 8, the connecting plate 705 drives the fixed plate 803 to move, which in turn drives the striking plate 801 to move. This causes one side of the striking plate 801 to contact one side of the supporting toothed plate 5, causing the striking plate 801 to rotate to one side around its bottom under force. This causes the striking plate 801 to drive the stroke groove 802 to move, which in turn drives the stroke rod 808 to move. The stroke rod 808 then drives the movable block 806 to move, causing the movable block 806 to squeeze and stretch the third springs 805 on both sides. This causes the third springs 805 to generate a rebound force. When the striking plate 801 is misaligned with the supporting toothed plate 5, the rebound of the third spring 805 causes the striking plate 801 to reset and move in the opposite direction. This causes the striking plate 801 to strike the next supporting toothed plate 5, causing the supporting toothed plate 5 to vibrate and shake off the attached waste debris. This prevents the waste debris from adhering to the surface of the supporting toothed plate 5 and damaging the next liquid cooling plate, thus avoiding affecting the subsequent welding quality.

[0050] Working principle: In use, the liquid cooling plate is placed on top of the support toothed plate 5, and then the electric push rod 605 drives the connecting plate 604 to move, which in turn drives the adjusting plate 603 to move. This causes the adjusting plate 603 to drive the transmission block 612 in the transmission groove 613 to move, which in turn drives the transmission rod 611 to move. This causes the transmission rod 611 to drive the fixed sleeve 602 to rotate, which in turn drives the rotating rod 601 to rotate, which in turn drives the support box 609. The support box 609 rotates, causing the fixing block 606 to rotate as well. The fixing block 606 located at the bottom of the liquid cooling plate contacts the bottom of the liquid cooling plate and contracts inward through compression. Meanwhile, one side of the outer fixing block 606 contacts one side of the liquid cooling plate, thus fixing the liquid cooling plate with the fixing block 606 and the baffle, preventing displacement of the liquid cooling plate during welding and affecting the welding quality. After welding is completed, the motor 710 drives the threaded rod 711 to rotate, which in turn moves the threaded seat 709, causing the threaded seat 709 to... The second connecting block 707 moves, which in turn moves the connecting plate 705. The connecting plate 705 then moves the top fixing plate 803, causing the fixing plate 803 to move the striking plate 801 and bring it into contact with one side of the support tooth plate 5. This causes the striking plate 801 to rotate to one side, which in turn moves the stroke rod 808 through the stroke groove 802. The stroke rod 808 then moves the movable block 806, causing the movable block 806 to stretch and compress the third spring 805, thus causing the third spring 805 to... 05 generates a rebound force. When one side of the striking plate 801 is misaligned with one side of the support toothed plate 5, the striking plate 801 is reset by the rebound of the third spring 805 and strikes the next support toothed plate 5. This causes the support toothed plate 5 to vibrate and shake off the waste chips, which fall onto the collection plate. The connecting plate 705 drives the support plate 712 to move, and the support plate 712 drives the support block 715 to move. This causes the support block 715 to drive the cleaning plate 708 to move, so that the cleaning plate 708 cleans the collection plate, thereby facilitating the collection of waste chips.
