Description

Technical Field

[0001] This invention relates to the field of water-cooled plate processing technology, specifically to a method of using a fully automatic water-cooled plate grinding and laser marking device. Background Technology

[0002] A water-cooled plate is a plate-shaped metal block with fluid channels arranged inside, enabling convective heat transfer between the fluid and the plate, thereby dissipating the heat dissipation of various electronic components connected to the plate surface. The advantage of water-cooled plates is that they can dissipate more heat per unit area compared to other heat dissipation structures. During the processing of water-cooled plates, especially after friction stir welding, the surface becomes very rough and requires polishing. However, currently available polishing tools are limited; therefore, it is necessary to propose a tool suitable for polishing water-cooled plates.

[0003] Chinese Patent Publication No. CN219234989U discloses a water-cooled plate grinding fixture, which relates to the field of grinding fixture technology. It includes a connector, a connecting seat connected to the bottom of the connector, an elastic pressing member provided on the bottom side of the connecting seat, clamping components provided on the left and right sides of the connecting seat, and a grinding member that extends downward from the left side of the connecting seat to the bottom side of the connecting seat, and then extends to the right side of the connecting seat from the bottom side of the connecting seat.

[0004] While this patent addresses the issue of limited grinding tools in the prior art to some extent, different grinding solutions are required for different water-cooled plates during grinding, and grinding fixtures alone cannot achieve the grinding of different water-cooled plates. Summary of the Invention

[0005] The purpose of this invention is to provide a method for using a fully automatic water-cooled plate grinding and laser marking device. By setting up continuous flat grinding equipment and automatic marking equipment stations, the flat grinding and marking work of the water-cooled plate is completed. Dust is removed by a dust removal equipment. The device has a high degree of automation and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for using a fully automatic water-cooled plate flipping, grinding, and laser marking device, comprising a flat grinding device, a dust removal device, a flipping device, a rib plate grinding device, and an automatic marking device, wherein the flat grinding device, dust removal device, flipping device, rib plate grinding device, and automatic marking device are connected in sequence, and a dust removal device is provided after both the flat grinding device and the rib plate grinding device. Both the flat grinding device and the rib plate grinding device include a grinding frame, a support platform, a lifting roller, a side-pushing assembly, and a front blocking device. The system includes a mechanism, a side blocking mechanism, a rotary clamping cylinder, and a three-axis servo module. A support platform is installed on the grinding frame, and a three-axis servo module is installed on the grinding frame above the support platform. A grinding device is installed on the three-axis servo module. A front blocking mechanism is installed on one side of the support platform, and a side blocking mechanism is installed at one end of the support platform. A rotary clamping cylinder is installed on the side of the support platform near the front blocking mechanism and the side blocking mechanism.

The robotic arm is connected to the mounting plate and the cap cylinder. The output end of the cap cylinder is connected to the rotary cylinder, and the output end of the rotary cylinder is connected to the cap body.

[0010] The operating method of the fully automatic water-cooled plate flipping, grinding, and laser marking device includes the following steps:

[0011] S1: When the water-cooled plate reaches the front blocking mechanism, the lifting roller stops rotating and descends. The water-cooled plate is placed on the support platform. The side push assembly pushes the water-cooled plate to the side blocking mechanism. Then, the rotary clamping cylinder presses down on the water-cooled plate, and the front blocking mechanism and the side blocking mechanism retract completely.

[0012] S2: The robotic arm moves the cap cylinder to the lower end of the water-cooled plate connecting pipe. The cap cylinder moves the cap body to cover the water-cooled plate connecting pipe and starts grinding. The pneumatic grinding head grinds with constant force. The dust generated during the grinding process is sucked away by the vacuum hood. After grinding, the cap cylinder retracts and the rotary cylinder drives the cap body to rotate 180°. The cap body is set facing down and air is blown into the cap body to clean the dust inside the cap body.

[0013] S3: The polished water-cooled plate is conveyed and moved by the conveyor roller. The brush rotates under the drive of the drive device to clean the water-cooled plate moving on the conveyor roller. The dust generated in the process is absorbed by the dust collection device in the dust cleaning frame.

[0014] S4: Select whether the product needs to be flipped and sanded on the back. After sanding, the product is moved to the automatic marking equipment for marking.

[0015] Preferably, the support platform has a movable groove that matches the roller on the lifting roller. The roller on the lifting roller passes through the movable groove. On the side of the support platform away from the front blocking mechanism, there are at least two sets of rotary clamping cylinders, and each set of rotary clamping cylinders is linearly distributed along the direction of the movable groove.

[0016] Preferably, the three-axis servo module includes an X-axis, a Y-axis, and a Z-axis. Both ends of the X-axis move on the Y-axis. At least one X-axis is provided. A Z-axis is provided on the X-axis, and a grinding device is connected to the Z-axis.

[0019] Preferably, the flipping device includes a conveyor belt, a flipping frame, and a clamping plate. The flipping frame is provided at both ends of the conveyor belt, and the clamping plate is provided at the output end of the flipping frame.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention completes the surface grinding and marking of water-cooled plates by setting up continuous surface grinding equipment and automatic marking equipment stations, and removes dust by dust removal equipment, achieving a high degree of automation;

[0032] 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.

[0033] To address the issue that existing methods require different grinding solutions for different water-cooling plates, and that grinding fixtures alone cannot achieve the grinding capabilities required for various water-cooling plates, please refer to [the relevant documentation / reference]. Figures 1-7 This embodiment provides the following technical solution:

[0034] A fully automatic water-cooled plate grinding and laser marking device includes a flat grinding device 1, a dust removal device 2 and an automatic marking device 3, which are connected in sequence, and the dust removal device 2 is provided after the flat grinding device 1.

[0035] Specifically, the process differs depending on the type of water-cooled plate being processed. The water-cooled plates produced by our company, models 680332 / 68051503 / 680371, are polished using this production line with the same polishing process, following a pre-set route. All parts that come into contact with the water-cooled plates, such as rollers and conveyor belts, are made of 100℃ high-temperature resistant materials.

[0036] The surface grinding equipment 1 includes a grinding frame 11, a support platform 12, a lifting roller 13, a side-pushing assembly 14, a front blocking mechanism 15, a side blocking mechanism 16, a rotary clamping cylinder 17, and a three-axis servo module 18. The support platform 12 is mounted on the grinding frame 11, and the three-axis servo module 18 is installed on the grinding frame 11 above the support platform 12. A grinding device 4 is mounted on the three-axis servo module 18. A front blocking mechanism 15 is located on one side of the support platform 12, and a side blocking mechanism 16 is located at one end of the support platform 12. Both the front blocking mechanism 15 and the side blocking mechanism 16 include a lifting cylinder and a blocking block. The grinding device 4 is adjusted by air pressure. The cylinder drives the blocking block to move up or down, thereby controlling the blocking block to block the water-cooled plate. After blocking the two adjacent sides of the water-cooled plate, the position of the water-cooled plate is determined. The support platform 12 is equipped with a rotary clamping cylinder 17 on the side near the front blocking mechanism 15 and the side blocking mechanism 16. The end of the support platform 12 away from the side blocking mechanism 16 is equipped with a side pushing assembly 14. The side pushing assembly 14 includes a side pushing cylinder and a pushing block. The side pushing cylinder pushes the pushing block to move in a straight line. The pushing block contacts the water-cooled plate and pushes the water-cooled plate to connect with the side blocking mechanism 16. The lifting roller 13 moves up and down along the vertical plane of the support platform 12.

[0037] The support platform 12 has a movable groove that matches the roller on the lifting roller 13. The roller on the lifting roller 13 passes through the movable groove. On the side of the support platform 12 away from the front blocking mechanism 15, there are at least two sets of rotary clamping cylinders 17. Each set of rotary clamping cylinders 17 is distributed in a straight line along the direction of the movable groove.

[0038] Specifically, when the lifting roller 13 moves upward, the roller on the lifting roller 13 is higher than the support platform 12. Through the rotation of the roller on the lifting roller 13, the water-cooled plate is moved to a different position. When the water-cooled plate contacts the front blocking mechanism 15, the lifting roller 13 descends and the water-cooled plate is placed on the support platform 12. The side pushing assembly 14 pushes the water-cooled plate to the side, so that the water-cooled plate is connected to the side blocking mechanism 16. The rotary clamping cylinder 17 is selected according to the model of the water-cooled plate and clamps the water-cooled plate at the appropriate position.

[0039] The three-axis servo module 18 includes an X-axis, a Y-axis, and a Z-axis. Both ends of the X-axis move on the Y-axis. There are two X-axis, and a Z-axis is set on the X-axis. A grinding device 4 is connected to the Z-axis. There are two grinding devices 4 on each of the two X-axis.

[0040] Specifically, drive devices are provided at both ends of the X-axis. The X-axis moves along the Y-axis direction, and the movement of the X-axis drives the Z-axis to move horizontally. At the same time, a drive device for horizontal movement is provided on the Z-axis to control the movement of the Z-axis on the X-axis. The Z-axis itself is a lifting cylinder that drives the grinding device 4 to move in the vertical direction.

[0041] The grinding device 4 includes a mounting plate 41 and a flexible grinding head 42. The mounting plate 41 is connected to the Z-axis, and the flexible grinding head 42 is connected to the mounting plate 41.

[0042] The flexible polishing head 42 includes a force control system 421, a pneumatic polishing head 422, and a vacuum shroud 423. The lower end of the force control system 421 is connected to the pneumatic polishing head 422, and the pneumatic polishing head 422 is covered with a vacuum shroud 423. A dust suction connector 4231 is connected to the vacuum shroud 423.

[0043] Specifically, the force control system 421 adopts the existing grinding force control system 421, which can achieve constant force grinding and ensure grinding effect. The pneumatic grinding head 422 can float axially by 40mm and angle by ±5°. The dust collection connector 4231 is connected to the dust collector 5 through a pipe. The dust generated during the grinding process is covered by the vacuum cover 423. The vacuum cover 423 forms a seal with the support surface to increase the dust collection effect, and the dust is absorbed by the dust collector 5.

[0044] The grinding device 4 also includes a cap assembly 43, which includes a cap cylinder 431, a rotary cylinder 432, a cap body 433, and a robotic arm 434. The robotic arm 434 is connected to the mounting plate 41 and is connected to the cap cylinder 431. The output end of the cap cylinder 431 is connected to the rotary cylinder 432, and the output end of the rotary cylinder 432 is connected to the cap body 433.

[0045] Specifically, the robotic arm 434 moves the cap cylinder 431 to the lower end of the water-cooled plate connecting pipe. The cap cylinder 431 then moves the cap body 433 to cover the water-cooled plate connecting pipe. During grinding, this prevents dust from entering the water-cooled plate connecting pipe. When not grinding, the cap cylinder 431 retracts, and the rotary cylinder 432 rotates the cap body 433 180°. The cap body 433 is then positioned downwards, and air is blown into the cap body 433 to clean the dust inside.

[0046] A dust sensor 111 is installed at the end of the grinding machine frame 11, and the dust sensor 111 is connected to a dust collector 5.

[0047] Specifically, when the dust collector 5 receives a signal from the dust sensor 111 and the amount of external dust exceeds the set value, the dust collector 5 is activated to remove dust from the working environment.

[0048] The dust removal device 2 includes a dust removal frame 21, a conveying roller 22, and a brush 23. The conveying roller 22 is installed on the dust removal frame 21, and the brush 23 is installed above the conveying roller 22.

[0049] Specifically, the polished water-cooled plate is conveyed and moved by the conveyor roller 22, and the brush 23 rotates under the drive of the drive device to clean the water-cooled plate moving on the conveyor roller 22. The dust generated in the process is absorbed by the dust collection device in the dust cleaning frame 21.

[0050] To better demonstrate the implementation process of the fully automatic water-cooled plate grinding and laser marking device, this embodiment presents a method for using the device, including the following steps:

[0051] Step 1: When the water-cooled plate reaches the front blocking mechanism 15, the lifting roller 13 stops rotating and descends. The water-cooled plate is placed on the support platform 12. The side pushing assembly 14 pushes the water-cooled plate to the side blocking mechanism 16. Then, the rotary clamping cylinder 17 presses down on the water-cooled plate, and the front blocking mechanism 15 and the side blocking mechanism 16 retract completely.

[0052] Step 2: The robotic arm 434 moves the cap cylinder 431 to the lower end of the water-cooled plate connecting pipe. The cap cylinder 431 moves the cap body 433 to cover the water-cooled plate connecting pipe and begin grinding. The pneumatic grinding head 422 grinds with constant force. The dust generated during the grinding process is sucked away by the vacuum cover 423. When it reaches the position of the rotary clamping cylinder 17, the rotary clamping cylinder 17 retracts. After the grinding is completed, the cap cylinder 431 retracts, and the rotary cylinder 432 drives the cap body 433 to rotate 180°. The cap body 433 is set facing downwards, and air is blown into the cap body 433 to clean the dust inside the cap body 433.

[0053] Step 3: The polished water-cooled plate is conveyed and moved by the conveyor roller 22. The brush 23 rotates under the drive of the drive device to clean the water-cooled plate moving on the conveyor roller 22. The dust generated in the process is absorbed by the dust collection device in the dust cleaning frame 21.

[0054] Step 4: After polishing, the product is moved to the automatic marking equipment 3 for marking.

[0055] In summary, the fully automatic water-cooled plate grinding and laser marking device proposed in this invention completes the grinding and marking of the water-cooled plate by setting up continuous flat grinding equipment 1 and automatic marking equipment 3 stations. Dust is removed by dust removal equipment 2, resulting in a high degree of automation. When the water-cooled plate reaches the front blocking mechanism 15, the lifting roller 13 descends, and the water-cooled plate is placed on the support platform 12. The side pushing component 14 pushes the water-cooled plate to the side blocking mechanism 16, and then the rotary clamping cylinder 17 presses down on the water-cooled plate, ensuring accurate positioning. The device also features a flexible... The grinding head 42 achieves constant force grinding, ensuring grinding effect. The vacuum cover 423 covers the dust generated during the grinding process, and the vacuum cover 423 forms a seal with the support surface to increase the dust collection effect. The dust is then absorbed by the dust collector 5. A cap assembly 43 is provided to prevent dust from entering the water-cooled plate connecting pipe during grinding. When not grinding, the cap cylinder 431 retracts, and the rotary cylinder 432 drives the cap body 433 to rotate. The cap body 433 is set downwards, and air is blown into the cap body 433 to clean the dust inside the cap body 433.
