Description

Technical Field

[0001] This disclosure relates to the field of VC heat sink manufacturing technology, and more specifically, to an automatic dot-cutting machine for heat dissipation VC copper sheets. Background Technology

[0002] The vapor chamber (VC) consists of a sealed metal shell, a vacuum chamber, a capillary wick, and a working fluid. The metal shell is typically made of thermally conductive copper and has recessed grooves to house the capillary wick. The capillary structure is usually a multi-layered copper mesh or sintered copper powder. The raw material is supplied in roll form, and during use, it needs to be stamped into structural sheets according to the shape of the shell grooves. Multiple sheets are then stacked, placed into the grooves, and finally sealed to form the chamber.

[0003] In the above process, the stacking and precise placement of multi-layer capillary sheets within the housing grooves largely relies on manual labor. However, manual operation makes it difficult to guarantee the accuracy and consistency of each stack, easily leading to problems such as capillary positioning deviations and uneven stacking, which in turn affect the final heat dissipation performance of the VC heat exchanger and result in a decrease in product yield. Therefore, there is an urgent need for an integrated device that can automatically complete the punching, stacking, placement, and fixing of capillary sheets. Summary of the Invention

Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] like Figures 1 to 18 As shown, this embodiment provides an automatic cutting and spot welding machine for heat dissipation VC copper sheets, which is used to automatically punch, stack and spot weld multi-layer copper capillary structure sheets into the groove 2 of the VC heat spreader plate 1.

[0042] The entire system is integrated into cabinet unit 100, which houses the electrical control system, pneumatic system, and PLC controller to coordinate the timing of actions of each unit. Each unit is equipped with sensors (including one or more of photoelectric sensors, pressure sensors, and temperature sensors) at key locations, and the sensor signals are connected to the PLC's input module. If any sensor signal fails to respond within a timeout period (the timeout period is adjustable from 1 to 5 seconds), the PLC controller stops the equipment and issues an audible and visual alarm.

[0043] First, the operator places the plate to be processed (e.g., plate 1) Figure 1 The plates (as shown) are neatly arranged and placed on the feeding unit 200. The feeding unit 200 supplies plates 1 in an orderly and intermittent manner. The first robotic arm 300, located next to the feeding unit 200, grabs the plates 1 and transfers them to the coding unit 400. The coding unit 400 performs laser coding on the back (non-grooved surface) of the plates 1 and reads the QR code to achieve traceability of each material.

[0044] After the marking is completed, the transfer mechanism moves the plate 1 to the flipping unit 500. The flipping unit 500 flips the plate 1 180 degrees so that the side with the groove 2 faces upward. At the same time, the feeding unit 600 starts working, which stacks and pre-spot welds the multi-layer copper sheets drawn from multiple copper sheet rolls 604 together, and then continuously feeds them to the stamping unit 700.

[0045] The stamping unit 700 punches multiple layers of copper sheets to form capillary sheets that match the shape of the groove 2. The punched capillary sheets briefly adhere to the upper die head 702 due to thermal deformation, and then naturally detach upon cooling. At this time, the second robotic arm 350 has placed the flipped plate 1 onto the receiving plate 704 of the stamping unit 700, directly below the upper die head 702. The detached capillary sheets fall precisely into the groove 2 of the plate 1. The second pressure plate 706 on the receiving plate 704 then presses down to maintain pressure and flatten any potentially warped capillary sheets after punching.

[0046] Subsequently, the second robotic arm 350 removes the plate 1 carrying the capillary structure sheet from the receiving plate 704 and transfers it to the spot welding reinforcement unit 800. The claws 8011 of the spot welding reinforcement unit 800 fix the plate 1, and the second spot welding gun 805 cooperates with the lifting support column 803 to spot weld and fix the capillary structure sheet in the groove 2 of the plate 1 at the designated position.

[0047] Finally, the receiving unit 900 removes the finished welded and reinforced plate 1 from the spot welding reinforcement unit 800 and neatly collects it into the collection and limiting frame 907. This completes the automatic punching, stacking, placement, and fixing of the capillary structure sheet.

[0048] like Figure 7 As shown, the board supply unit 200 includes a base plate 201 fixed to the cabinet unit 100. Two sets of first linear actuators 202 (e.g., linear guides or rodless cylinders) are mounted on the base plate 201. A transfer bin 203 is detachably mounted on each of the first linear actuators 202 via insertion / removal or pin positioning. Multiple vertical grooves are evenly spaced on the transfer bin 203, allowing the boards 1 to be vertically and evenly inserted into these grooves for easy gripping by the first robotic arm 300. The first linear actuators 202 drive the transfer bin 203 to move stepwise, causing the boards 1 to be gripped to sequentially reach the picking position.

[0049] like Figure 8As shown, the first robotic arm 300 includes a multi-degree-of-freedom robotic arm 301. A first electric pusher 302 is fixedly mounted on the output end of the robotic arm 301. A deflection frame 303 is hinged to the outer shell of the first electric pusher 302, and its output end is also hinged to the deflection frame 303. A suction cup frame 304 is mounted on the deflection frame 303, and its suction cup position can be adjusted according to the position of the groove 2. During operation, the first electric pusher 302 extends, driving the deflection frame 303 to rotate 90 degrees, so that the suction cup frame 304 faces the vertically placed plate 1, adsorbs the plate 1, lifts it, and then rotates 90 degrees in the opposite direction to make the plate 1 horizontal. Finally, the robotic arm 301 transfers it to the coding unit 400.

[0050] like Figure 9 As shown, the second robotic arm 350 also uses a similar robotic arm, but its end effector is different. A mounting frame 352 is installed on the lifting end of the robotic arm of the second robotic arm 350. A second electric push block 354 is fixed to the upper part of the mounting frame 352, and its drive end is connected to a first pressure plate 355. Two symmetrically arranged bottom support plates 353 are located directly below the first pressure plate 355, with a gap between the two bottom support plates 353. This design is because unfixed capillary sheets have already been placed on the plate 1, which cannot be transferred by adsorption. Therefore, the bottom support plates 353 support the bottom of the plate 1, and the first pressure plate 355 gently presses down on the capillary sheets from above, achieving stable transfer.

[0051] like Figure 10 As shown, the coding unit 400 includes a first longitudinal and transverse drive 401 fixed on the cabinet unit 100. The longitudinal and transverse drive is composed of two interlocking electric linear guides connected to each other, allowing it to move in the XY plane. A first lifting device 402 is installed at the drive end of the drive unit 401, and a laser engraving machine 403 is installed at the lifting end of the first lifting device 402. A support platform 405 is provided below the laser engraving machine 403, and a first contour plate 406 is slidably mounted on the support platform 405 via a slide rail. The first contour plate 406 has a notch that matches the shape of the plate 1. An electric push rod 407 drives the first contour plate 406 to move horizontally to avoid the material feeding action of the first robotic arm 300. After the plate 1 is placed, the first contour plate 406 moves back to directly below the laser engraving machine 403, and the laser engraving machine 403 engraves the back of the plate 1. Then, the scanning module 404 reads the QR code to enter it into the system.

[0052] like Figure 11 and Figure 12As shown, the flipping unit 500 includes a second longitudinal and transverse driver 503, a second lifting device 504, an electric turntable 505, and an electric gripper 506. The second contour plate 502 is used to place the plate 1 to be flipped. The transfer mechanism includes a horizontally positioned second linear driver 501 and a first transfer bracket 507 on its driving end. The first transfer bracket 507 is equipped with a third electric push block 5071, which can move up and down. During operation, the transfer mechanism moves the plate 1 from the first contour plate 406 of the marking unit 400 to the second contour plate 502. Then, driven by the second longitudinal and transverse driver 503 and the second lifting device 504, the electric gripper 506 clamps the plate 1, and the electric turntable 505 rotates 180 degrees and then lowers, achieving flipping, with the groove 2 facing upwards.

[0053] like Figures 13 to 15 As shown, the feeding unit 600 includes multiple support plates 601 (four in this embodiment), each support plate 601 is equipped with two load-bearing limiting rollers 602 for rotatably mounting the copper sheet rolls 604. Below the load-bearing limiting rollers 602, a constraint roller 603 is provided for guiding and constraining the copper sheets to prevent interlayer friction. A pressure roller drive 605 is configured in the direction in which the copper sheet rolls 604 are drawn out. The pressure roller drive 605 includes multiple rollers and a motor that drives the rollers to rotate. The multi-layered copper sheets drawn out from the multiple copper sheet rolls 604 are pressed, clamped, and pulled forward by the pressure roller drive 605.

[0054] A third linear drive 606 is horizontally positioned in the output direction of the pressure roller drive 605, on which a liftable first spot welding gun 607 is mounted. When the pressure roller drive 605 pauses intermittently, the first spot welding gun 607 descends, pre-fixing the multiple layers of copper sheets together by spot welding. The spot welding spacing is 30-50mm, arranged in a straight line along the copper sheet conveying direction, with at least two weld points per row. The purpose of this pre-spot welding process is to prevent interlayer misalignment of the multiple layers of copper sheets during subsequent punching and conveying. On the other side of the punching unit 700, a tail drive pressure roller group 608 is provided for pulling out the scrap material after punching.

[0055] like Figure 15 As shown, the stamping unit 700 includes a stamping press 701, which has an upper die head 702 and a lower die head 7021. A fourth linear actuator 703 is horizontally mounted on the stamping press 701, and a receiving plate 704 is mounted on its driving end. The receiving plate 704 is provided with a positioning structure (such as a contour groove or positioning pin) for placing the plate 1. The second robot arm 350 places the flipped plate 1 onto the receiving plate 704. The multi-layer copper sheet conveyed by the feeding unit 600 passes between the upper die head 702 and the lower die head 7021.

[0056] When the stamping press 701 operates, the upper die 702 descends to cut out capillary sheets. Due to the heat generated during stamping (the copper sheet experiences an instantaneous temperature rise of approximately 40-60°C), the capillary sheets temporarily adhere to the upper die 702 due to micro-deformation caused by thermal expansion and contraction, as well as the adsorption effect between the capillary sheets and the die surface. After stamping is completed, the upper die 702 is held at its highest position for a certain period of time, such as 4-8 seconds, allowing the capillary sheets to cool and shrink before naturally detaching under gravity.

[0057] As the upper die head 702 rises, the receiving plate 704 moves rapidly to directly below the upper die head 702 under the drive of the fourth linear actuator 703. The vertical distance between the receiving plate 704 and the upper die head 702 is 8-12mm. After cooling, the capillary sheet naturally falls off and into the groove 2 of the lower plate 1.

[0058] Subsequently, the receiving plate 704 retracts below the upper die head 702. A fourth electric push block 705, suspended above the receiving plate 704, is mounted on the back of the fourth linear actuator 703. A second pressure plate 706 is mounted on the movable end of the fourth electric push block 705. The fourth electric push block 705, located above the receiving plate 704, drives the second pressure plate 706 to press down, maintaining pressure and flattening the capillary structure sheet within the groove 2 to eliminate warping. The pressure parameters are: pressure 3-5N, pressure holding time 3-4 seconds. A 0.5mm thick silicone buffer layer is attached to the pressing surface of the second pressure plate 706 to avoid damaging the capillary structure.

[0059] like Figure 16 and Figure 17 As shown, the spot welding reinforcement unit 800 includes a third contour plate 801, which has a notch and a movable claw 8011. Below the third contour plate 801 is a third longitudinal and transverse actuator 802, whose driving end is equipped with a liftable lifting support column 803. A fourth longitudinal and transverse actuator 804 is located on the side, whose driving end is equipped with a second spot welding gun 805. Furthermore, a CCD scanning module 806 is also installed on the side of the fourth longitudinal and transverse actuator 804.

[0060] After the second robotic arm 350 removes the plate 1 carrying the capillary structure sheet from the stamping unit 700, it first passes through the CCD scanning module 806 to scan the QR code on the bottom surface of the plate 1 and record the production status. Then, the second robotic arm 350 places the plate 1 into the recess of the third contour plate 801. The chuck 8011 extends under the drive of the electric push block and clamps the edge of the plate 1.

[0061] Next, the third longitudinal and transverse actuators 802 and the fourth longitudinal and transverse actuators 804 work together to move the lifting support column 803 and the second spot welding gun 805 to the preset welding point. The lifting support column 803 rises and presses against the bottom of the plate 1, while the second spot welding gun 805 descends to spot weld and reinforce the capillary structure sheet and the plate 1.

[0062] like Figure 18 As shown, the receiving unit 900 includes a similar transfer mechanism as described above, and multiple fourth contour plates 902 as transfer stations (two in this embodiment). The transfer mechanism sequentially moves the finished product plate 1 from the third contour plate 801 to the fourth contour plate 902. A sixth linear actuator 904 is located beside the last fourth contour plate 902, with a liftable lifting push rod 905 mounted on its drive end. A first transfer bracket 507 with a suction cup is mounted on the lifting push rod 905. The suction cup adheres to the finished product plate 1 and moves it into the collection limiting frame 907 on the side. The collection limiting frame 907 consists of multiple vertical plates, with the plate 1 vertically inserted into the gaps between the plates. An infrared sensor is located at the top of the collection limiting frame 907, which issues a prompt when the plate 1 is full.

[0065] (3) The innovative pre-fixing and pressure holding design: the first spot welding gun in the feeding unit pre-welds the multi-layer copper sheets together to prevent misalignment between layers after punching; the second pressure plate of the stamping unit holds pressure and flattens the capillary sheets that may warp after punching to ensure the reliability of subsequent welding.

[0066] (4) Information is traceable throughout the process. The coding unit generates a unique QR code for each board. Combined with the CCD scanning module at the spot welding reinforcement unit, the production data can be tracked throughout the process, which is convenient for quality control.
