Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and more specifically to a liquid cooling plate welding machine. Background Technology

[0002] Liquid coolers, as a highly efficient heat dissipation component, are typically assembled and welded from multiple layers of components (such as cover plates, cavities, and heat dissipation fins). In traditional liquid cooler manufacturing processes, multiple steps, including loading, alignment, water injection, pre-pressurization, and welding of each component, often rely on manual labor or dispersed equipment. This production method has significant drawbacks: First, manual operation is inefficient, resulting in a slow production cycle and making it difficult to meet the demands of large-scale automated production; second, misalignment can easily occur as components move between multiple workstations, and the accuracy of water injection quantity and position is difficult to guarantee, leading to poor product sealing and low yield; finally, the dispersed operations also occupy a significant amount of production space.

[0023] The liquid-cooled sheet welding machine of this utility model embodiment is described in detail below with reference to the accompanying drawings. The liquid-cooled sheet is assembled from a first workpiece, a second workpiece, and a third workpiece.

[0024] Please see Figures 1-13In this embodiment, the system includes: a workbench 1; a first storage mechanism 2, which is disposed on the workbench 1 and can rotate or move up and down in a second direction to store a first workpiece; a hollow rotary platform 3, which is disposed on the workbench 1 and has a turntable 4; a first picking mechanism 5, which is disposed on the workbench 1 and spaced apart on the top of the first storage mechanism 2 and the turntable 4, and can reciprocate in a first direction or move up and down in a second direction to transport the first workpiece from the first storage mechanism 2 to the turntable 4; and multiple placement mechanisms 6, which are equally spaced on the hollow rotary platform 3 and are suitable for placing the first workpiece. The system comprises: a first workpiece, a second workpiece, and a third workpiece; a feeder mechanism 7, which is located on the worktable 1 and spaced apart from the turntable 4, and can hold a material roll, suitable for transporting the material roll to the worktable 1; an adsorption mechanism 8, located inside the feeder mechanism 7, which can move up and down in a second direction to adsorb the material roll transported to the worktable 1 by the feeder mechanism 7; a first laser mechanism 9, located on the worktable 1 and spaced apart on top of the adsorption mechanism 8, suitable for cutting the material roll adsorbed by the adsorption mechanism 8; and a feeding mechanism 10, located on top of the feeder mechanism 7, which can reciprocate in a first direction or move up and down in a second direction to feed the second workpiece on the adsorption mechanism 8. The workpiece is transported to the storage mechanism 6 containing the first workpiece; a water injection mechanism 11, located at the end of the feeder mechanism 7 and movable in a first direction, is used to inject condensate into the storage mechanism 6 containing the first and second workpieces, so that the condensate covers the second workpiece; a second storage mechanism 12, located on the worktable 1 and spaced apart from the feeder mechanism 7, is rotatable or movable in a second direction on the worktable 1 to store a third workpiece, and has the same structure as the first storage mechanism 2; a second picking mechanism 13, located on the worktable 1 and spaced apart from the top of the second storage mechanism 12 and the turntable 4. The second material handling mechanism 13 is adapted to transport the third workpiece on the second material handling mechanism 12 to the placement mechanism 6 on which the first workpiece and the second workpiece are placed, so that the first workpiece and the third workpiece jointly clamp the second workpiece, and the second material handling mechanism 13 has the same structure as the first material handling mechanism 5; the pressing mechanism 14 is provided on the worktable 1 and spaced apart on the top of the turntable 4, and the pressing mechanism 14 can rise or fall in the second direction to be adapted to press the first workpiece, the second workpiece and the third workpiece together; the limiting mechanism 15 is provided on the worktable 1 and is provided in the same vertical direction as the pressing mechanism 14, and the limiting mechanism 15 can rise and fall in the second direction. When the pressing mechanism 14 descends to press, the limiting mechanism 15 rises in the second direction and abuts against the placement mechanism 6;The second laser mechanism 16 is located on the worktable 1 and spaced apart on top of the pressing mechanism 14. The second laser mechanism 16 and the first laser mechanism 9 have the same structure. When the pressing mechanism 14 presses on the first workpiece, the second workpiece and the third workpiece, the second laser mechanism 16 performs laser welding on the first workpiece, the second workpiece and the third workpiece to assemble the first workpiece, the second workpiece and the third workpiece into a liquid cooling sheet. Then the hollow rotating platform 3 rotates the liquid cooling sheet to the bottom of the first material handling mechanism 5 so that the first material handling mechanism 5 places the liquid cooling sheet on the first material storage mechanism 2 or in an external storage box. The first storage mechanism 2 stores the first workpiece and delivers it to the picking position by rotation or lifting. The first picking mechanism 5 moves in the horizontal (first direction) and vertical (second direction) directions to pick up the first workpiece and place it in the placement mechanism 6 on the hollow rotating platform 3. The turntable 4 rotates to send the fixture 601 containing the first workpiece to the next station. The feeder mechanism 7 transports the roll carrying the second workpiece to the working position, the adsorption mechanism 8 rises and adsorbs the second workpiece on the roll, and the first laser mechanism 9 operates to cut the roll according to the preset path and separate the individual second workpiece. Subsequently, the feeding mechanism 10 moves above the adsorption mechanism 8, picks up the separated second workpiece, moves above the turntable 4, and precisely places it on the placement mechanism 6 which already contains the first workpiece; the water injection mechanism 11 moves horizontally above the placement mechanism 6 and injects a certain amount of condensate into it, so that the condensate covers the surface of the second workpiece. The second storage mechanism 12 stores the third workpiece, and the second picking mechanism 13 picks it up and transports it to the top of the turntable 4, placing it on the second workpiece that has been injected with water, so that the first workpiece and the third workpiece clamp the second workpiece from the top and bottom sides to form a semi-finished assembly to be welded. Turntable 4 rotates the assembly to the pressing station; pressing mechanism 14 descends to press the three layers of workpiece together to ensure their relative positions are fixed. At the same time, the lower limiting mechanism 15 rises to abut against and fix the placement mechanism 6, preventing it from shifting or deforming during pressing and welding. Subsequently, the second laser mechanism 16 emits a laser to scan and weld along the workpiece seam, permanently welding the three layers of workpiece into a complete liquid cooling sheet. After welding, the pressing mechanism 14 and the limiting mechanism 15 are reset. The turntable 4 rotates to send the finished liquid cooling sheet to the unloading station. The first material handling mechanism 5 can then operate again to remove the finished product and place it into the first storage mechanism 2 or an external storage box, completing a complete work cycle.

[0025] In this embodiment, the first material storage mechanism 2 includes: a rotary cylinder 201, which is disposed on the workbench 1; a fixed plate 202, which is disposed on the transmission end of the rotary cylinder 201; two material boxes 203, which are respectively spaced apart from the fixed plate 202; two positioning holes 204, which are respectively disposed at the bottom of the two material boxes 203 and respectively penetrate the bottom of the fixed plate 202; a fixed frame 205, which is disposed inside the workbench 1; a first lifting cylinder 206, which is disposed at the bottom of the fixed frame 205 and whose transmission end extends into the fixed frame 205; and a lifting rod 207, which is vertically disposed inside the fixed frame 205 and connected to the transmission end of the first lifting cylinder 206, and whose lifting rod 207 corresponds to the positioning hole 204. Two material boxes 203 are defined as follows: one is the raw material area, used to store the unprocessed first workpiece; the other is defined as the finished product area, used to receive the finished liquid cooling sheet after welding. In the initial state, the raw material area is located at the material picking station. When material needs to be loaded, the first lifting cylinder 206 located at the bottom of the fixed frame 205 is activated, and its transmission end pushes the lifting rod 207 to move upward. The lifting rod 207 passes through the positioning hole 204 at the bottom of the fixed plate 202 and precisely extends into the bottom of the material box 203 located at the material picking station, lifting the stacked first workpiece as a whole, ensuring that the topmost workpiece is at a height position that can be reliably picked up by the suction cup 506 of the first picking mechanism 5. After the material is picked up, the first lifting cylinder 206 retracts, driving the lifting rod 207 to descend and reset, and the remaining workpiece falls back into the material box 203. When the first workpiece in the raw material area is picked up, and it is necessary to switch the empty box in the finished product area to the raw material station and remove the raw material box that is full of finished products, the rotary cylinder 201 is started, driving the fixed plate 202 on its top and the two material boxes 203 on the fixed plate 202 to rotate 180 degrees. This causes the original finished product area (empty box) to rotate to the picking station, ready to receive the new first workpiece; while the original raw material area (now empty) rotates to the finished product station, ready to receive the subsequent finished liquid cooling plates, thus realizing the functional interchange of the two stations. By setting up two material boxes 203 and equipping them with rotary cylinders 201, the raw material storage and finished product collection functions are integrated into the same mechanism. When the raw material in one material box 203 is exhausted, there is no need to stop the machine and manually change the material. The empty finished product box can be automatically rotated 180 degrees to switch to the raw material station, ensuring the continuity and efficiency of equipment production and greatly reducing the production interruption time caused by loading / unloading. The lifting rod 207 driven by the first lifting cylinder 206 lifts the entire stack of workpieces, which can always maintain the top workpiece at a constant and optimal picking height. This effectively avoids the problem of the picking mechanism not being able to pick up or colliding with workpieces due to the workpiece stack height decreasing, and greatly improves the success rate and stability of automatic picking operation. The structure of the lifting rod 207 cooperating with the positioning hole 204 at the bottom of the material box 203 ensures that the force is transmitted evenly and vertically during the lifting process, avoiding workpiece jamming or tilting. The entire mechanism is integrated into the worktable 1, with a compact structure and high space utilization. At the same time, mechanical positioning ensures the repeatability of the operation.

[0026] In this embodiment, the first material handling mechanism 5 includes: a support frame 501; a first lead screw module 502, which is disposed on the support frame 501 and arranged along a first direction; a first sliding plate 503, which is slidably disposed on the first lead screw module 502; two second lifting cylinders 504, which are respectively disposed at both ends of the first sliding plate 503 and arranged along a second direction; two connecting frames 505, which are respectively disposed on the transmission ends of the two second lifting cylinders 504; and two sets of suction cups 506, which are respectively disposed on the two connecting frames 505, with at least two suction cups in each set, which are respectively disposed at both ends of the connecting frame 505. The first lead screw module 502 drives the entire first slide plate 503 to move horizontally (first direction), causing its two second lifting cylinders 504 and their end suction cups 506 to stop precisely above the material box 203 of the first storage mechanism 2 and the placement mechanism 6 of the hollow rotating platform 3, respectively. The second lifting cylinder 504 located above the first storage mechanism 2 is activated, driving the connecting frame 505 and the suction cups 506 below it to descend vertically (second direction). After the suction cups 506 contact and pick up the first workpiece, the lifting cylinder rises to complete the material retrieval. At the same time or shortly thereafter, the other second lifting cylinder 504 located above the placement mechanism 6 is also activated and descends, causing its suction cups 506 to pick up the welded liquid cooling sheet, and then rises to complete the finished product retrieval operation. The two lifting cylinders can be controlled independently to achieve coordinated operations of picking up and placing one or both simultaneously. The first lead screw module 502 actuates again, moving the entire first slide plate 503 horizontally, causing the two lifting cylinder units to exchange positions. The unit carrying the first workpiece moves above the turntable 4, while the unit carrying the finished liquid cooling sheet moves above the finished product material box 203 of the first storage mechanism 2. The lifting cylinder that has moved above the turntable 4 descends, placing the picked-up first workpiece onto the empty placement mechanism 6. Then, the suction cup 506 breaks the vacuum, and the lifting cylinder rises. The other lifting cylinder that has moved above the first storage mechanism 2 descends synchronously, placing the picked-up finished liquid cooling sheet into the material box 203, which serves as the finished product area, and then resets. After this, the first lead screw module 502 drives the mechanism to reset, preparing for the next work cycle. By setting up two independent lifting cylinder units, this mechanism can simultaneously complete two sets of actions, "raw material pick-up - finished product pick-up" and "raw material placement - finished product placement," in one horizontal round trip. Compared to the traditional single-suction head material handling mechanism, which requires two separate loading and unloading strokes, this greatly shortens the production cycle and significantly improves production efficiency. The two functional units (one dedicated to raw materials and the other to finished products) are spatially independent and switch workstations by horizontal movement, fundamentally avoiding the risks of cross-contamination, program misjudgment, or mechanical interference that may arise from using the same set of suction cups 506 to pick up raw materials and finished products sequentially. The operation logic is clear and reliable; the two second lifting cylinders 504 are located at both ends of the first slide plate 503. This symmetrical layout design makes the force more balanced during horizontal movement and lifting operations, reducing the shaking and wear caused by uneven load, improving the smoothness of movement and positioning accuracy, and also extending the service life of the equipment; each set of suction cups 506 has at least two and is distributed at both ends of the connecting frame 505. This design can smoothly pick up the workpiece and prevent thin sheet-like workpieces or finished products from bending, deforming or falling off due to uneven force during the picking and placing process, effectively protecting the product and ensuring a high yield rate.

[0027] In this embodiment, the placement mechanism 6 includes: a fixture 601 disposed on the turntable 4; a plurality of fixing rods 602 respectively disposed vertically at the bottom of the fixture 601 along a first direction and extending to the bottom of the turntable 4; abutment plate 603 disposed at the bottom of the plurality of fixing rods 602; and two limiting blocks 604 disposed opposite to each other at the bottom of the abutment plate 603, forming a positioning groove between the two limiting blocks 604, and the two limiting blocks 604 being L-shaped. The fixture 601 is used to directly support the first, second, and third workpieces. The fixing rod 602 rigidly connects the fixture 601 to the bottom abutment plate 603, forming a sturdy overall frame. This frame is mounted on the turntable 4 via the abutment plate 603 and rotates with the turntable 4, moving between various workstations. When the turntable 4 rotates, transporting the workpiece-loaded placement mechanism 6 to the workstation requiring pressing and welding, the limiting mechanism 15 rises in the second direction (vertical direction). At this time, the positioning groove formed by the two L-shaped limiting blocks 604 located at the bottom of the abutment plate 603 precisely fits into the top of the rising limiting mechanism 15. The L-shaped structure completely constrains the limiting mechanism 15 on the horizontal plane, preventing it from moving in any direction. Only when the limiting mechanism 15 completely locks the placement mechanism 6 on the horizontal plane via the positioning groove can the pressing mechanism 14 above descend to perform the pressing operation. The vertical downward pressure applied by the pressing mechanism 14 is transmitted through the workpiece to the fixture 601, and then through the fixing rod 602 to the abutment plate 603 and the turntable 4 below. At this time, the limiting mechanism 15 mainly resists the horizontal force (such as the small lateral force or vibration that may be generated during welding), while the vertical pressure is borne by the structure of the entire placement mechanism 6 and the turntable 4. The two work together to ensure the absolute stability of the pressing and welding process. The mechanical engagement of the positioning groove and the limiting mechanism 15 achieves complete constraint on all degrees of freedom of the placement mechanism 6 in the horizontal plane, forming an extremely stable "ground pile" effect. It can effectively resist the thermal stress, vibration and lateral force generated when the pressing mechanism 14 presses down during laser welding, fundamentally eliminating the slight shaking of the fixture 601 at the critical station, and providing crucial stability guarantee for high-precision welding. The positioning groove formed by the two L-shaped limiting blocks 604, together with the top of the limiting mechanism 15, constitutes a precise mechanical positioning system. Every time it rotates to the station, it can achieve extremely high repeatability positioning through this system, ensuring that the fixture 601 (and the workpiece on it) can stop in the exact same position every time. This is a prerequisite for ensuring the consistency of the laser welding path and the sealing of the product; the rigid connection design from fixture 601 to fixed rod 602 and then to abutment plate 603 forms a solid whole; when bearing the downward pressure of pressing mechanism 14, the force flow transmission path is clear and direct, avoiding the generation of weak links, preventing the mechanism from deforming due to long-term load, and ensuring the service life and long-term accuracy of the equipment; the entire placement mechanism 6 (fixture 601, fixed rod 602, abutment plate 603, limit block 604) can be installed on turntable 4 as an independent module through abutment plate 603; this design facilitates quick installation, disassembly and replacement, and if fixture 601 wears due to long-term use, it can be easily replaced or maintained, reducing equipment downtime.

[0028] In this embodiment, the feeder mechanism 7 includes: a mounting frame 701; an extension plate 702, the bottom of which is vertically provided with the mounting frame 701, and the extension plate 702 is L-shaped; a first motor 703, located on the inner side of one bottom end of the extension plate 702, and the drive shaft of the first motor 703 extends to the outer side of the extension plate 702; a first material winding wheel 704, located on the inner side of the other bottom end of the extension plate 702, and the fixed shaft inside the first material winding wheel 704 extends to the outer side of the extension plate 702; and a first rotating wheel 705, located on the extension plate 702. The extension plate 702 is located on the outer side of its bottom and is sleeved on the drive shaft of the first motor 703; the second rotating wheel 706 is located on the outer side of the bottom of the extension plate 702 and is sleeved on the fixed shaft of the first material winding wheel 704; the belt 707 is sleeved on the first rotating wheel 705 and the second rotating wheel 706; the second motor 708 is located on the outer side of the middle part of the extension plate 702; the second material winding wheel 709 is located on the inner side of the middle part of the extension plate 702, and the fixed shaft of the second material winding wheel 709 extends to the outer side of the extension plate 702 and is connected to the second motor. The drive shaft of 708 is connected; a third motor 710 is located on the outer rear end of the mounting frame 701; a first roller 711 is rotatably located on the inner rear end of the mounting frame 701, and the inner circumference of the first roller 711 extends to the outer side of the mounting frame 701 and is connected to the drive shaft of the third motor 710; two sliding grooves 712 are respectively located on both sides of the inner rear end of the mounting frame 701 and are spaced apart on the top of the first roller 711; two bearing seats 713 are slidably located in the two sliding grooves 712; and a second roller 714. The second roller 714 is rotatably disposed between two bearing seats 713, and both ends of the second roller 714 are rotatably connected to the two bearing seats 713 respectively; two third lifting cylinders 715 are respectively disposed on the top of both sides of the mounting frame 701 along the first direction, and the transmission ends of the two third lifting cylinders 715 are respectively connected to the two bearing seats 713; a third roller 716 is rotatably disposed in the middle of the mounting frame 701; a fourth roller 717 is rotatably disposed in the middle of the mounting frame 701 and is spaced apart at the bottom of the third roller 716; The operator installs the strip carrying the second workpiece onto the second strip reel 709, which serves as the unloading tray. The strip is manually pulled out from the beginning and passed through a preset path. First, the strip passes through a roller assembly consisting of a first roller 711 (drive roller) and a second roller 714 (adjustable clamping roller). The second roller 714 is raised and lowered by two third lifting cylinders 715 to clamp or loosen the strip. The strip is then laid flat and positioned at the first adsorption plate 804 on the adsorption mechanism 8. The second motor 708 directly drives the second material roll 709 (feeding tray) to actively feed material; the third motor 710 drives the first roller 711 (active drive wheel) to rotate, providing the main traction force for the material belt to move forward; the first motor 703 drives the first material roll 704 (take-up tray) to actively take up material through the belt 707; by controlling the downward pressure of the second roller 714 (pressure roller) and the speed coordination between the second roller 711, the feeding motor, and the take-up motor, it is ensured that the material belt maintains a stable and appropriate tension during the conveying process, avoiding the material belt from becoming loose, shaking, or being stretched and deformed; the third motor 710 drives the first roller 711 to rotate at a specific angle to achieve fixed-distance and precise positioning of the material belt, accurately stepping the next second workpiece on the material belt directly above the adsorption station; The system employs servo motors (second motor 708, third motor 710) and precision rollers to precisely control the feeding stroke of the material strip. This ensures that each second workpiece is accurately delivered to the adsorption cutting station, forming the foundation for successful subsequent laser cutting and adsorption placement processes, and significantly improving the overall processing accuracy of the equipment. The adjustable second roller 714 (pressure roller), in conjunction with active feeding, active winding, and active traction, forms a closed-loop tension control system. This effectively eliminates slackness, vibration, or serpentine deviation of the material strip caused by inertia, ensuring the strip remains flat, taut, and in a constant position during transport. This not only protects the precision workpieces on the strip from damage but also provides a stable working surface for laser cutting, avoiding cutting errors caused by vibration. This mechanism highly integrates feeding, tension control, traction positioning, and waste material winding functions. Once the initial feeding is completed, the entire feeding process can operate fully automatically in a loop, requiring no frequent manual intervention or adjustment. This significantly improves production efficiency, reduces inconsistencies and downtime caused by manual operation, and meets the needs of modern intelligent manufacturing.

[0029] In this embodiment, the adsorption mechanism 8 includes: an inner support 801, which is disposed in the middle of the mounting frame 701; a fourth lifting cylinder 802, which is disposed at the bottom of the inner support 801 along a first direction, and the transmission end of the fourth lifting cylinder 802 extends into the interior of the inner support 801; a vacuum hood 803, which is disposed at the top of the fourth lifting cylinder 802; a first adsorption plate 804, which is disposed at the top of the vacuum hood 803, and the middle of the first adsorption plate 804 has a protruding contouring platform; and a limiting frame 805, which is disposed inside the mounting frame 701 and spaced apart from the first adsorption plate 804. The top of the limiting frame 805; two fifth lifting cylinders 806, each located on the bottom sides of one end of the limiting frame 805, with their transmission ends extending to the top of the limiting frame 805; a first limiting plate 807, located on top of the two fifth lifting cylinders 806; two sixth lifting cylinders 808, each located on the bottom sides of the other end of the limiting frame 805, with their transmission ends extending to the top of the limiting frame 805; and a second limiting plate 809, located on top of the two sixth lifting cylinders 808. After the feeder mechanism 7 conveys the material belt to the working position, the fourth lifting cylinder 802 is activated, pushing the vacuum cover 803 and the first adsorption plate 804 on its top to rise, so that the first adsorption plate 804 comes into contact with the material belt. The protruding contouring stage in the middle of the first adsorption plate 804 matches the contour of the second workpiece, allowing it to be precisely embedded into the cavity or bottom of the strip that supports the second workpiece, thus achieving pre-positioning and ensuring that the workpiece will not move on the horizontal plane. After the contouring stage completes the initial positioning, the vacuum system is activated, generating negative pressure through the vacuum hood 803 and the air passage on the first adsorption plate 804 (not shown in the figure, but a standard industry design), firmly adsorbing the strip onto the surface of the first adsorption plate 804. This step eliminates any gaps between the strip and the adsorption plate, ensuring a tight fit and providing an extremely stable foundation for laser cutting. While adsorbing and fixing, the fifth lifting cylinder 806 and the sixth lifting cylinder 808 on both sides drive the first limiting plate 807 and the second limiting plate 809 to descend, respectively, pressing the strip from both ends or sides. This provides additional lateral limiting force, effectively preventing any minor slippage or vibration that may occur during the cutting process. The top contour of the protrusion (contouring stage) of the first adsorption plate 804 matches the shape of the second workpiece to be cut. The laser head of the first laser mechanism 9 will scan and cut strictly according to the edge contour of this boss. Since the strip is vacuum-adsorbed and closely adheres to the contour table, the laser cutting path completely coincides with the contour of the actual workpiece, ensuring extremely high cutting precision and consistency; Initial positioning is achieved through the mechanical engagement of the contour stage and the workpiece cavity, followed by vacuum adsorption to ensure complete fit of the material strip. This dual protection ensures zero deviation between the workpiece and its theoretical position during the cutting process. Laser cutting along the edge of the boss fundamentally eliminates the recognition errors that may exist in traditional visual positioning, achieving high-precision contour cutting with excellent dimensional consistency of the cut workpieces. Vacuum adsorption completely eliminates the gap between the material strip and the substrate, while the lateral limiting plate counteracts lateral forces. This rigid fixing method effectively suppresses the thermal stress and vibration generated during laser cutting, avoiding defects such as rough cut surfaces, slag buildup, or even overheating caused by material vibration, thus obtaining a clean, smooth, and burr-free high-quality cut surface.

[0030] In this embodiment, the first laser mechanism 9 includes: a manual lifting platform 901, which is disposed on the worktable 1 along a first direction; a slide 902, which is slidably disposed on the manual lifting platform 901; and a laser emitter 903, which is disposed on the slide 902, and the emitting end of the laser emitter 903 and the protrusion of the first adsorption plate 804 are disposed in the same vertical direction. The operator first operates the manual lifting platform 901 to drive the entire slide table 902 and its laser emitter 903 to move up and down in the vertical direction (first direction). The purpose of this operation is to precisely adjust the focal position of the laser on the workpiece surface (i.e., the contour table surface of the first adsorption plate 804 of the adsorption mechanism 8). Through manual fine adjustment, the energy density of the laser beam is ensured to be at its optimal state to obtain the cleanest and most efficient cutting effect. After determining the optimal focal length, the operator can slide the slide table 902 to fine-tune the position of the laser emitter 903 on the horizontal plane. The purpose of this step is to ensure that the emitting end of the laser emitter 903 is on the same vertical axis as the contour table on the first adsorption plate 804 below, that is, to ensure that the laser cutting path completely coincides with the contour of the contour table and avoid any deviation. After completing the above calibration and locking the position, the mechanism enters the automatic working mode. When the adsorption mechanism 8 positions and fixes the material strip, the laser emitter 903 emits laser according to the preset program and scans along the edge contour of the contour table, thereby accurately cutting and separating the individual second workpiece from the material strip. The combination of the manual lifting platform 901 and the slide 902 provides an extremely precise and vibration-free adjustment method. Compared to the motor-driven automatic focusing mechanism, manual adjustment completely avoids the slight vibration and backlash caused by motor operation, allowing operators to make extremely fine and stable adjustments. This enables nanometer-level precision focus positioning and alignment calibration, which is a key prerequisite for achieving perfect cutting quality. Once the initial calibration is completed and locked, the position of the mechanism will not change throughout the entire production batch. This rigid locking structure avoids the slight drift that the automatic adjustment mechanism may experience due to long-term operation, temperature drift, or electrical signal interference, ensuring that each workpiece is cut with exactly the same focal length and position parameters, thereby guaranteeing a high degree of consistency and reliability in the cutting quality of each product in mass production.

[0031] In this embodiment, the feeding mechanism 10 includes: a second lead screw module 1001, which is disposed on the outside of the mounting frame 701 and arranged along a second direction; two slide rails 1002, which are respectively disposed on both sides of the top of the mounting frame 701 and arranged along the second direction; a second slide plate 1003, which is slidably disposed on the top of the two slide rails 1002, and the side of the second slide plate 1003 is connected to the transmission end of the second lead screw module 1001; two seventh lifting cylinders 1004, which are respectively disposed at both ends of the top of the second slide plate 1003 along a first direction, and the transmission ends of the two seventh lifting cylinders 1004 extend to the bottom of the second slide plate 1003; and a second adsorption plate 1005, which is connected to the transmission ends of the two seventh lifting cylinders 1004, and the bottom of the second adsorption plate 1005 is provided with a boss with the same shape as the first adsorption plate 804. The second lead screw module 1001 serves as the core driving component, precisely controlling the movement of the second slide plate 1003 in the horizontal direction (second direction), enabling the second adsorption plate 1005 at its end to reciprocate between directly above the adsorption mechanism 8 (cutting station) and directly above the fixture 601 on the turntable 4; when the second adsorption plate 1005 moves above the adsorption mechanism 8, the two seventh lifting cylinders 1004 operate synchronously, pushing the second adsorption plate 1005 to descend in the vertical direction. The protrusion at the bottom of the second adsorption plate 1005 (whose shape is the same as the contour stage of the first adsorption plate 804) will precisely embed into or align with the contour of the second workpiece that has been laser-cut and separated. Subsequently, the vacuum system on the second adsorption plate 1005 will be activated to firmly hold the second workpiece. After completion, the seventh lifting cylinder 1004 will rise, carrying the workpiece away. The second lead screw module 1001 will drive the entire mechanism to move, transporting the second workpiece to the jig 601 on the turntable 4, which is already loaded with the first workpiece. Subsequently, the seventh lifting cylinder 1004 will descend synchronously again, smoothly placing the second workpiece into the designated position in the jig 601. The vacuum will be released, the cylinder will rise, and the mechanism will return to the standby position, completing one work cycle. The high-precision translational motion provided by the second lead screw module 1001 and the smooth vertical motion ensured by the two seventh lifting cylinders 1004 ensure the accuracy of the transport path. The protrusion design at the bottom of the second adsorption plate 1005 is crucial. It plays a guiding and positioning role when picking up the workpiece, ensuring that the workpiece is in the predetermined posture when picked up. This allows the workpiece to be placed with extreme precision on the first workpiece in the fixture 601, laying a perfect alignment foundation for subsequent water injection and pressing processes, and effectively avoiding yield problems caused by misalignment. The symmetrical layout of two seventh lifting cylinders 1004 and two slide rails 1002 ensures that the second adsorption plate 1005 is subjected to uniform force during lifting and lowering, runs smoothly, and has no risk of shaking or tilting. This design ensures that the thin and fragile second workpiece will not shift, fall off, or deform due to mechanism vibration during high-speed picking and placing, greatly improving the reliability of handling operations and product safety. The kinematic pair formed by the second lead screw module 1001 and the double slide rails 1002 has high rigidity and guiding accuracy, enabling fast, smooth, and precise point-to-point movement, shortening cycle time and improving the overall production efficiency of the machine.

[0032] In this embodiment, the water injection mechanism 11 includes: two first slide rods 1101, which are respectively disposed at the front end of the mounting frame 701 and arranged along the second direction, and are slidably connected to the mounting frame 701; an air rod 1102, which is disposed on the outer side of the front end of the mounting frame 701, and the transmission end of the air rod 1102 extends into the mounting frame 701; a shelf 1103, which is disposed at the front end inside the mounting frame 701, and is connected to the transmission ends of the first slide rods 1101 and the air rod 1102; two storage bottles 1104, which are respectively spaced apart on the shelf 1103; and two injection guns 1105, which are respectively disposed at the bottom of the two shelves 1103 and are respectively connected to the two storage bottles 1104. After the second workpiece is placed on the first workpiece, the pneumatic rod 1102 is activated, and its transmission end pushes the shelf 1103 to move smoothly and precisely along the track defined by the two first slide rods 1101 in the second direction (horizontal direction) until the injection gun 1105 is accurately positioned directly above the water injection area in the fixture 601. After the shelf 1103 moves into place, the system controls the injection gun 1105, which is connected to the storage bottle 1104, to perform the water injection action. The injection gun 1105, through its internal precision mechanism (such as a screw pump or precision cylinder pushing the piston), draws a certain amount of condensed water from the storage bottle 1104 and injects it precisely into the fixture 601 below, so that the condensed water covers the second workpiece. After the water injection action is completed, the pneumatic rod 1102 retracts, pulling the entire shelf 1103 back to the initial position (i.e., the front end of the feeder mechanism 7) along the first slide rod 1101, thereby making room and avoiding interference with the rotation of the turntable 4 to the next station. Driven by the pneumatic spring 1102, the mechanism achieves automatic addressing and positioning of the water injection station. Combined with the quantitative function of the injection gun 1105, it can strictly control the dosage of condensate injected each time, ensuring a high degree of consistency in the amount of water injected into each liquid cooling plate. This fundamentally solves the problems of inaccurate dosage, low efficiency, and poor consistency in manual water injection, greatly improving the performance consistency and yield of the product. The guide design of two first sliding rods 1101 ensures that the shelf 1103 has good rigidity and smooth movement when it moves horizontally under the push of the pneumatic spring 1102, without shaking or jamming, ensuring that the injection gun 1105 can repeatedly reach the same water injection position each time. The storage bottle 1104, injection gun 1105 and drive unit are integrated into a shelf 1103, which has a compact structure, reasonable layout, and facilitates overall installation, debugging and maintenance.

[0033] In this embodiment, the pressing mechanism 14 includes: a support platform 1401, which is positioned on the worktable 1 in a first direction; a third lead screw module 1402, which is positioned inside the support platform 1401 in the first direction; a sliding frame 1403, which is connected to the transmission end of the third lead screw module 1402; a plurality of second slide rods 1404, which are respectively positioned at the corners of the sliding frame 1403 along the first direction and extend to the top of the sliding frame 1403 and are slidably connected to the sliding frame 1403; and a plurality of blocking blocks 1405, which are respectively positioned on the plurality of second slide rods 1404. The top of 4; pressure plate 1406, which is located at the bottom of multiple second slide rods 1404, and a welding path groove is provided in the middle of the pressure plate 1406; multiple springs 1407, which are respectively sleeved on the outer periphery of multiple second slide rods 1404, one end of the spring 1407 is connected to the bottom of the sliding frame 1403, and the other end is connected to the top of the pressure plate 1406; the limiting mechanism 15 includes: an eighth lifting cylinder 1501, which is located on the worktable 1 along the first direction; a lifting block 1502, which is located at the transmission end of the eighth lifting cylinder 1501, and the lifting block 1502 corresponds to the positioning groove; After the placement mechanism 6, carrying three stacked workpieces, rotates to the welding station, the limiting mechanism 15 activates first. Its eighth lifting cylinder 1501 drives the lifting block 1502 to rise, precisely embedding it into the positioning groove at the bottom of the placement mechanism 6, completely locking all degrees of freedom on the horizontal plane, providing an absolutely stable base for subsequent pressing. Subsequently, the pressing mechanism 14 begins to operate, and the third lead screw module 1402 drives the sliding frame 1403 to descend vertically, causing the pressure plate 1406 to approach the workpiece. When the pressure plate 1406 contacts the workpiece and continues to press down, multiple second sliding rods 1404 slide upward relative to the sliding frame 1403, forcing multiple springs 1407 to be compressed. The reaction force generated by the compression of the springs 1407 is applied to the workpiece through the pressure plate 1406, forming a constant and flexible clamping force, tightly pressing the three layers of workpieces together and eliminating the layering. The gap is between the two sides; at the same time, multiple blocking blocks 1405 descend together with the sliding frame 1403. When the spring 1407 is compressed to the predetermined stroke, the blocking block 1405 will contact (or approach to a very small distance) the top of the pressure plate 1406, forming a mechanical hard limit to prevent excessive pressure due to overload of the spring 1407, which could damage the precision workpiece; in the absolutely stable state where the placement mechanism 6 is locked by the lifting block 1502 and the workpiece is pressed by the flexible pressure plate 1406 with constant force, the second laser mechanism 16 is activated, and the laser beam scans and welds the workpiece joint through the welding path groove in the middle of the pressure plate 1406; in the absolutely stable state where the placement mechanism 6 is locked by the lifting block 1502 and the workpiece is pressed by the flexible pressure plate 1406 with constant force, the second laser mechanism 16 is activated, and the laser beam scans and welds the workpiece joint through the welding path groove in the middle of the pressure plate 1406. The design, combining spring 1407 buffering with mechanical hard limiting, provides a constant, adjustable clamping force with overload protection. Flexible pressure ensures tight adhesion between workpiece layers while completely avoiding the risk of excessive pressure, damage, or crushing of precision workpieces due to errors in the downward stroke or slight variations in workpiece thickness, greatly improving production safety and yield. The limiting mechanism 15, through mechanical interlocking between the lifting block 1502 and the positioning groove, provides extreme rigidity against horizontal forces; the pressing mechanism 14 provides stable clamping force in the vertical direction. Together, they create an extremely stable processing environment in three-dimensional space, effectively suppressing thermal stress and vibration generated during laser welding, ensuring the stability of the laser focus position, and thus achieving high yield. The high-quality sealed weld; the welding path groove design in the middle of the pressure plate 1406 provides a clear and unobstructed scanning path for the laser beam of the second laser mechanism 16, allowing the laser head to move freely above the workpiece and complete the welding of the entire ring or a specific trajectory without the need for mechanism avoidance, simplifying programming and operation; the pressing is driven by the third lead screw module 1402 and the limiting is driven by the eighth lifting cylinder 1501. Both of these driving methods have the characteristics of high precision, high rigidity and high reliability, ensuring the repeatability of positioning accuracy and long-term working stability of each pressing and locking action, meeting the stringent requirements of automated production equipment for key workstations.
