Description

Technical Field

[0001] This application relates to the field of cold plate processing technology, and in particular to a smart processing method and system for cold plates. Background Technology

[0002] Cold plate, generally refers to the heat dissipation mechanism in electronic devices. It is used to conduct heat between media, so it is usually made of metal with good thermal conductivity.

[0003] The processing of cold-rolled metal sheets can be carried out using machine tools. A brief description of one processing procedure is as follows: First, the machine tool is positioned and calibrated, then the sheet is placed on the processing table for milling. After the milling is completed, the machined holes are used to position and fix the sheet in place with tooling, and then subsequent cutting and grinding processes are carried out.

[0004] In the above process, the tooling on the sheet metal after milling the holes needs to be manually operated. If the worker is not careful at this time, for example, if the sheet metal and the tooling fixture are misaligned, even if the subsequent processing is correct, the positioning error will accumulate and increase, which will affect the product quality. Summary of the Invention

[0005] In order to reduce processing errors and improve product quality during the cold plate processing process, this application provides a smart processing method and system for cold plates.

[0014] The locking mechanism selects the appropriate tooling fixture and fixes it to the tooling table;

[0015] The sheet metal is moved to the transfer mechanism by the moving mechanism, and the sheet metal is moved to the tooling fixture on the tooling table by the transfer mechanism.

[0016] The locking mechanism aligns the sheet metal and tooling fixture, and locks them in place by cooperating with the pre-milled holes on the sheet metal.

[0017] The machine tool performs forming work on the sheet metal on the tooling table.

[0018] Secondly, this application provides a processing system, which adopts the following technical solution:

[0019] A machining system includes a machine tool and a tooling table mounted on the front side of the machine tool table, and also includes a controller and a moving mechanism 1, a transmission mechanism, a locking mechanism, and a moving mechanism 2 electrically connected to the controller.

[0020] The first moving mechanism includes:

[0027] The conveyor belt is directed toward the tooling table, there are two guide rods, the sheet material is placed between the two guide rods, and the paper is located below the guide rods.

[0028] Optionally, the conveying mechanism further includes a stop bar and a drive unit 1. The stop bar is located below the guide bar and is rotatably connected to the conveyor belt body. The drive unit 1 is installed on the conveyor belt and drives the stop bar to rotate. The stop bar drives the paper downward.

[0029] Optionally, the tooling table includes a base and a reference seat fixed to the base, the reference seat having a transverse sliding groove, and the locking mechanism including:

[0030] Tooling placement plate, with its sliding connection groove;

[0031] Drive unit two is mounted on the reference base and is used to drive the tooling placement plate to slide.

[0032] A pin-connecting mechanism used to connect tooling placement plates and reference seats;

[0033] The tooling placement plate has multiple placement slots for placing tooling fixtures. The section of the tooling placement plate that extends into the slide groove has multiple pin holes. The pin holes are arranged along the length of the tooling placement plate, and each pin hole corresponds to a placement slot.

A rack structure is provided at the lower part of the tooling placement plate, and the length of the rack structure extends along the length direction of the tooling placement plate and meshes with the gear.

[0035] Optionally, the locking mechanism further includes a locking rod and a cylinder. The cylinder is embedded in the reference seat with the telescopic rod facing upwards. The locking rod is fixed to the telescopic rod end of the cylinder and is used to pass through the tooling fixture and insert into the hole milled in the sheet metal. The controller is also connected to a camera and a laser ranging unit. The camera and laser ranging unit are mounted above the tooling table and face downwards towards the tooling table. The controller is configured as follows:

[0036] Based on the video data fed back by the camera, the sheet metal features are identified, and the position of the sheet metal features in the image is analyzed and calculated to obtain the image measurement results;

[0037] The position of the sheet metal is analyzed based on the detection value fed back by the laser ranging unit to obtain the laser measurement result;

[0041] The liquid volume control component includes an electric cylinder II, a liquid storage cylinder, and a liquid delivery pipe. The liquid storage cylinder is hollow inside and has openings at both ends as a push port and a discharge port.

That is, the manual operation steps after milling holes in the sheet metal are replaced by the machine and can be automated, thereby eliminating subjective errors of manual operation and achieving higher precision. Furthermore, because parameters such as the displacement of the sheet metal are synchronized to the machine during machine operation, the machine can track and update the new coordinates of the sheet metal in real time. As a result, the errors generated in subsequent processing of the sheet metal are relatively smaller, and the product quality is higher. Attached Figure Description

[0051] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0052] This application discloses an intelligent processing method for cold-rolled steel plates.

[0053] Reference Figure 1 and Figure 2 The intelligent processing method for cold-rolled steel plates includes the following steps:

[0054] Step 1: Establish a moving mechanism 1, which includes: setting a horizontal displacement adsorption plate 11 on the machining table, with the displacement direction facing the tooling table 3.

[0055] In this embodiment, machining can be carried out by a CNC machine tool. It should be noted that the machine tool 4 in this embodiment should have a flat table 41 to form the required table surface; and the table 41 should have a large number of vacuum adsorption holes 42 evenly opened. The vacuum adsorption holes 42 are connected to a vacuum pumping device through pipes on the back of the table 41 to meet the temporary adsorption and fixation function of the cold plate material during machining.

[0056] Step 2: Establish a transfer mechanism 5, which includes: setting up a transfer mechanism 5 between the machining table and the tooling table 3. It is understood that in this embodiment, the table 41 does not extend beyond the machine tool 4 body; the tooling table 3 is simply another device on the machine body in front of the table 41 (i.e., facing the user's standing position). The transfer direction of the transfer mechanism 5 is at least from the table to the tooling table 3 in front of the table.

[0057] Step 3: Establish the locking mechanism 6 for the sheet metal, which includes: setting a locking mechanism 6 on the tooling table 3 to select a matching tooling fixture 7 according to the user's instructions, and the locking mechanism 6 delivering and fixing the tooling fixture 7 to the tooling table 3.

[0058] Step 4: Establish a second moving mechanism 2, which includes: setting up a second moving mechanism 2 below the tooling table 3, and the moving direction is vertical, that is, the second moving mechanism 2 is used to lift the tooling table 3.

[0059] Step 5, intelligent processing, includes:

[0060] S11, Paper is placed on the adsorption plate 11 and board material is placed on the paper;

[0061] The adsorption plate 11 is used to place the cold plate material, so the area of ​​the adsorption plate 11 is at least larger than the area of ​​the plate material. The reason for placing paper is that when milling holes in the plate material, debris will be generated. Without the paper pad, the debris can easily enter the vacuum channel. In addition, the plate material is often coarse and has a rough surface. Without the paper pad, it may not be able to adhere tightly to the table surface, affecting the vacuum adsorption effect. This is existing technology and will not be elaborated further.

[0062] S12. Machine tool 4 mills holes in the plate on the adsorption plate 11. The milling hole positions are preset by the operator.

[0063] S13. The locking mechanism 6 selects the appropriate tooling fixture 7 and fixes it to the tooling table 3.

[0064] S14. The sheet metal is moved to the transfer mechanism 5 by the moving mechanism 1, and the sheet metal is moved to the tooling fixture 7 of the tooling table 3 by the transfer mechanism 5.

[0065] S15. Align the sheet metal and tooling fixture 7 with locking mechanism 6, and lock them in place by cooperating with the pre-milled holes on the sheet metal.

[0066] S16. Machine tool 4 performs forming work on the sheet metal on tooling table 3.

[0067] Based on the above setup, this method achieves automated transfer of sheet metal through the cooperation of moving mechanism 1 and transfer mechanism 5. At the same time, locking mechanism 6 fixes the sheet metal and tooling fixture 7, and fixes the tooling fixture 7 and tooling table 3. That is, the manual operation steps after milling holes in the sheet metal are replaced by the machine and can be automated, thereby eliminating subjective errors of manual operation and achieving higher precision. Furthermore, because parameters such as the displacement of the sheet metal are synchronized to the machine during machine operation, the machine can track and update the new coordinates of the sheet metal in real time. As a result, the errors generated in subsequent processing of the sheet metal are relatively smaller, and the product quality is higher.

[0068] This application also discloses a processing system.

[0069] Reference Figure 2 and Figure 3The processing system includes a machine tool 4, a tooling table 3 mounted on the front side of the table 41 of the machine tool 4, a controller 8, and a moving mechanism 1, a transmission mechanism 5, a locking mechanism 6, and a moving mechanism 2 electrically connected to the controller 8.

[0070] In this embodiment, the controller 8 can be the control system of a CNC machine tool to reduce costs; if this application is based on the renovation of an existing old machine tool, the controller 8 can be a separate PLC controller and a host connected to the PLC controller.

[0071] The aforementioned moving mechanism 1 includes an adsorption plate 11 and a linear actuator 12. The adsorption plate 11 is placed laterally on the table 41 of the machine tool 4 and has multiple air holes 13 along the thickness direction. The end of the adsorption plate 11 extends to the side of the table 41, that is, its length is greater than that of the cold plate. It should be noted that the moving path of the air holes 13 on the adsorption plate 11 should be directly above the arrangement direction of the vacuum adsorption holes 42 on the table 41.

[0072] Linear actuator 12 is mounted on the machine body of machine tool 4 on the side of the table, and the slider is connected to the end of adsorption plate 11. The adsorption plate 11 and the slider can be fixed by bolts and nuts. Linear actuator 12 can be a linear motor or a lead screw slide. On the opposite side of the table (i.e., opposite the lead screw slide), a guide rod can be set. The other end of the adsorption plate 11 is penetrated by the long rod, which assists the movement of the adsorption plate 11. The driving direction of linear actuator 12 is parallel to the arrangement direction of the machine tool table 4 and the tooling table 3.

[0073] With the above settings, the controller 8 can control the moving mechanism 1, the transmission mechanism 5, the locking mechanism 6 and the moving mechanism 2 to perform their work, thereby achieving precise movement of the cold plate. Compared with manual movement of the plate, this is more precise, effectively reducing the probability of plate and tooling fixture 7 being fixed off-center, reducing positioning errors and improving the quality of the final product.

[0074] Reference Figure 2 and Figure 4 The transmission mechanism 5 includes a linear driver 51, a conveyor belt 52, and a guide rod 53. The linear driver 51 can be a linear motor, which is fixed to the machine body of the machine tool 4 by a bottom support structure. The linear motor is installed between the table 41 and the tooling table 3 of the machine tool 4, and the driving direction is laterally perpendicular to the arrangement direction of the table 41 and the tooling table 3.

[0075] The conveyor belt 52 is fixed to the slider of the linear motor. The conveyor belt 52 can be a belt drive structure and the belt is a synchronous belt. The conveyor belt 52 is separated from the platform 41 and the upper surface of the belt is not higher than the platform 41, such as being at the same height as the upper surface of the platform 41. The conveying direction of the conveyor belt 52 is towards the tooling table 3.

[0076] There are two guide rods 53. One end of the guide rod 53 is set on the body of the conveyor belt 52, and the other end extends toward the platform 41. The two guide rods 53 are located on both sides of the conveyor belt 52 and are parallel to each other. The sheet is placed between the two guide rods 53 and the side wall of the sheet is close to the guide rod 53. The paper is located below the guide rod 53.

[0077] Based on the above settings

[0078] First, the part of the sheet facing the front of the machine tool 4 should extend out of the suction plate 11 so that when the suction plate 11 moves the sheet outward, the front part of the sheet can overlap the conveyor belt 52.

[0079] Secondly, when the sheet metal is overlapped onto the conveyor belt 52, as the conveyor belt 52 operates, the sheet metal is driven towards the tooling table 3, thereby achieving the transfer;

[0080] Furthermore, because the conveyor belt 52 and the table 41 are separated, and the paper is known to be flexible, the paper under the board will automatically droop at one end and automatically separate as the board moves before the board is delivered to the conveyor belt 52.

[0081] Furthermore, because the conveyor belt 52 is mounted on the linear drive 51, the position of the conveyor belt 52 is adjustable, meaning the position of the sheet material does not have to be fixed.

[0082] Finally, guide rod 53 is used to guide and limit the displacement direction of the sheet metal, preventing the sheet metal from tilting during movement, thereby reducing the possibility of errors in subsequent processing and improving the quality of cold sheet metal processing.

[0083] Furthermore, in order to adapt the conveying mechanism 5 to sheet metal of different sizes, the guide rod 53 is configured to slide and connect to the body of the conveyor belt 52, and the sliding direction is parallel to the driving direction of the linear drive 51; a sliding seat is fixed on the body of the conveyor belt 52, a sliding groove is opened in the sliding seat and a connector is slidably connected in the sliding groove, the connector and the guide rod 53 are fixed and drive the guide rod 53 to slide, and the connector is threaded with two nuts, the nuts abut against the sliding seat, and the connector is locked by the double nuts.

[0084] According to the above settings, the staff can loosen the nut to allow the guide rod 53 to slide. After adjusting the distance between the two guide rods 53 according to the size of the sheet material, tightening the nut will complete the fixing.

[0085] Reference Figure 4 The transmission mechanism 5 also includes a stop bar 54 and a drive unit 1. The stop bar 54 is cylindrical and located below the guide rod 53. It is rotatably connected to the body of the conveyor belt 52 through a support structure.

[0086] Drive unit one can be a servo motor. Drive unit one is mounted on conveyor belt 52 (e.g., a bracket is fixed on the body of conveyor belt 52, and the motor is mounted on the bracket). The output shaft of drive unit one is fixed to stop rod 54 through a coupling and is used to drive stop rod 54 to rotate. Taking a person facing machine tool 4 as an example, when looking at stop rod 54 from the right side of the person, stop rod 54 rotates clockwise.

[0087] Due to the different hardness of the paper, softer paper will quickly droop at the end after moving the edge of the platen 41 without interfering with the transfer of the board. However, if the paper is harder, the end will not droop, or only droop slightly, and it will easily continue to move with the board, causing interference. With the above setting, as long as the paper is not curled up and is completely straight, the rotation and friction of the stop bar 54 can ensure that the paper moves downward, without affecting the transfer of the board, thereby achieving the separation of the paper from the board, and the structure is simple.

[0088] Reference Figure 5 and Figure 6 The tooling table 3 includes a base 31 and a reference seat 32 fixed to the base 31. The base 31 serves as a foundation and has a frustum structure. The reference seat 32 is fixed to the base 31 by bolts and has a transverse sliding groove.

[0089] The locking mechanism 6 includes a tooling placement plate 61, a drive unit 62, and a pin connection mechanism. The bottom forming slider of the tooling placement plate 61 is slidably connected to a slide groove. The tooling placement plate 61 has multiple placement slots for placing the tooling fixture 7, arranged along its length and having an upward opening structure. The section of the tooling placement plate 61 extending into the slide groove, i.e., the aforementioned slider, has multiple pin holes 64, arranged along the length of the tooling placement plate 61. Each pin hole 64 corresponds one-to-one with a placement slot; that is, each placement slot has a horizontal pin hole 64 at its bottom.

[0090] The pin-connecting mechanism is used to connect the tooling placement plate 61 and the reference base 32, thereby fixing the required tooling fixture 7 directly above the reference base 32 for fixed placement of the sheet metal. The pin-connecting mechanism includes a pneumatic, hydraulic, or electric telescopic unit 63, such as a cylinder. The cylinder body is fixed to the reference base 32, and the telescopic rod passes through the reference base 32. The telescopic end of the cylinder is fixed with a pin that can extend into a sliding groove. The end of the pin that extends into the pin hole 64 can be tapered, that is, the diameter of the end of the pin that extends into the pin hole 64 is smaller, and the diameter of the end connecting the telescopic end of the cylinder is larger. The drive unit 62 is mounted on the reference base 32 and is used to drive the tooling placement plate 61 to slide.

[0091] With the above setup, different tooling fixtures 7 can be placed simultaneously in the tooling placement plate 61. When a particular tooling fixture 7 is needed, the tooling placement plate 61 can be moved by the drive unit 62 to change the tooling fixture 7, thus making the system more versatile. At the same time, since the tooling fixture 7 is only moved laterally, there is no need to repeatedly pick up and put back the tooling fixture 7, so it is simpler and more convenient to use, and there is no need to install too many unnecessary structures.

[0092] The reason for using a pin to fix the selected sliding tooling placement plate 61 is that the selected tooling fixture 7 can be directly fixed above the reference base 32. Compared with other fixing methods (such as screw insertion and abutment fixing), the pin hole 64 is pre-opened based on the preset fixing position of the tooling fixture 7. After the pin is inserted, the fixing position error is smaller, improving the accuracy of the tooling fixture 7 installation position. In addition, the end of the pin is set to be tapered as described above, considering that the pin may wear after repeated use. The tapered setting allows it to automatically abut against the pin and the pin hole 64 after being pushed in, reducing the impact of wear on the pin (such as gaps after wear causing vibration when cutting cold plates), and improving the quality of cold plate production.

[0093] Reference Figure 5 and Figure 6 The aforementioned drive unit 62 includes a servo motor 621 and a gear 622 fixed to the output shaft of the servo motor 621. The reference base may have a groove for mounting the gear 622, with the gear 622 placed in the mounting groove. The servo motor 621 is fixed to the outer wall of the reference base 32, and the output shaft of the servo motor 621 is fixed to the center of the gear 622.

[0094] A rack structure 611 is provided on the wall of the tooling placement plate 61 facing the reference base 32. The length of the rack structure 611 extends along the length direction of the tooling placement plate 61. The tooth structure of the gear 622 can partially extend out of the mounting groove, and the rack structure 611 meshes with the gear 622.

[0095] With the above configuration, the tooling placement plate 61 is driven to move by the gear 622 and rack structure 611 in conjunction with the servo motor 621. Compared with other methods of sliding the tooling placement plate 61 (such as using an electric cylinder to push it), its structure is more compact and simple. At the same time, the gear 622 pushes the tooling placement plate 61 to slide with high precision, which meets the requirement that the tooling fixture 7 needs to be accurately placed above the reference base 32.

[0096] The locking mechanism 6 also includes a locking rod 65 and a cylinder. The cylinder is installed in a pre-drilled hole in the reference base and is vertically positioned. The locking rod 65 is fixed to the upward telescopic rod end of the cylinder. The locking rod 65 is used to lock the sheet metal by passing through the milled hole. This setting replaces the original method of fixing with screws, which is more convenient and faster, and improves the efficiency of processing cold plates.

[0097] Based on the above, the controller 8 is also connected to a camera 81 and a laser ranging unit 82. The laser ranging unit 82 is a laser ranging sensor. The camera 81 and the laser ranging unit 82 are mounted above the fixture 3 and face the fixture 3 when viewed from above. The controller 8 is configured as follows:

[0098] S21. Based on the video data fed back by camera 81, identify the sheet metal features and analyze and calculate the position of the sheet metal features in the image to obtain the image measurement results; Example:

[0099] The video data is framed to obtain images, and image recognition is performed on the images. The target of recognition is the sheet metal, and the outline of the sheet metal is marked. The pixel position of the sheet metal in the image is determined based on the outline of the sheet metal, and the pixel position is used as the image measurement result.

[0100] S22. Analyze the position of the sheet metal based on the detection value fed back by the laser ranging unit 82, and obtain the laser measurement result;

[0101] Example: The detection end of laser ranging unit 82 points vertically downwards, and the detection line falls on the edge of fixture 7 facing the user; at this time, the position of the analyzed sheet metal is:

[0102] Before the sheet material is delivered, the measured value is h1±h2, where h2 is the allowable fluctuation error; the measurement result at this time is: the sheet material has not arrived.

[0103] When the sheet metal moves into place, the detection value suddenly changes to h3, and h3 < h1 - h2. At this time, the measurement result is that the sheet metal has moved into place.

[0104] S23. Compare the image measurement results and the laser measurement results. For example, if the pixel position is aligned with the preset standard position of the preset tooling fixture 7, and the laser measurement result shows that the sheet metal has moved into place, then the results are consistent.

[0105] If the results are consistent, then control the conveyor belt 52 and the cylinder to work according to the measurement results;

[0106] If the results are inconsistent, indicating a machine vision failure or a laser ranging failure, a machine failure message will be output. The message can be displayed by the controller 8 being electrically connected to a monitor located to the side of the machine tool 4 in this application, with the message appearing as a pop-up window on the monitor to alert the operator.

[0107] According to the above settings, a laser ranging unit 82 is also installed along with the camera 81. The two work together to measure and analyze the position of the sheet metal. By comparing the results of the two, the probability of errors is reduced compared to the results obtained by installing only the camera 81 or only the laser ranging unit 82, thereby improving the quality of the final product.

[0108] Reference Figure 5 The second moving mechanism 2 includes an electric cylinder 21, a limiting unit 22, and a laser ranging unit 23 (e.g., a laser ranging sensor). The electric cylinder 21 is vertically arranged and its body is fixed to the machine tool 4 (e.g., a support structure fixed to the machine tool 4). The base 31 of the tooling table 3 is fixed to the telescopic end of the electric cylinder 21. The electric cylinder 21 is used to drive the tooling table 3 to rise and fall. The limiting unit 22 is installed on the machine tool 4 through a frame and is used to temporarily restrict the movement of the base 31, thereby effectively preventing the base 31 from pushing the electric cylinder 21 downward when the sheet metal is subjected to downward force during processing, thus reducing the error caused by displacement during sheet metal processing.

[0109] Laser ranging unit 23 is installed on machine tool 4 with its detection end facing upward. It is used to detect the distance between the laser ranging unit 23 and the base 31. Laser ranging unit 23 is electrically connected to controller 8 to output the position detection data of base 31, which is used to analyze and determine whether the tooling table 3 has been raised or lowered to the execution height.

[0110] Reference Figure 5 and Figure 6 The limiting unit 22 includes a telescopic sleeve 221 installed on the machine tool 4 and a liquid volume control component. There are multiple telescopic sleeves 221, which are divided into multiple groups of two. A limiting block 33 (e.g., a ring-shaped ring) is fixed on the outside of the base 31 of the tooling table 3. The telescopic sleeves 221 are symmetrically arranged along the limiting block 33 and are symmetrically arranged vertically as a group.

[0111] The telescopic sleeve 221 is divided into two sections, one of which is a fixed section and the other is a movable section. The movable section extends and retracts from the fixed section. The fixed section of the telescopic sleeve 221 is fixed to the machine tool 4 by a support structure. The fixed section is hollow inside and has a liquid inlet on its outer wall. The end of the movable section abuts against the limiting block 33.

[0112] The liquid control assembly includes an electric cylinder 222, a liquid storage cylinder 223, and a liquid delivery pipe. The liquid storage cylinder 223 is mounted on the machine tool 4, is hollow inside and filled with liquid. The two ends of the liquid storage cylinder 223 are open as a push port and a discharge port. The telescopic end of the electric cylinder 222 is fixed (e.g., fixed after being sleeved) with a piston, and the telescopic end extends into the liquid storage cylinder 223 through the push port. The diameter of the push port is smaller than the diameter of the piston. One end of the liquid delivery pipe is connected to the discharge port of the liquid storage cylinder 223 through a pipe joint, and the other end is connected to the liquid inlet of the telescopic sleeve 221.

[0113] With the above settings, the extension and retraction of the electric cylinder 222 can be controlled, pushing the piston to extend and retract in the liquid storage cylinder 223, thereby pushing out the liquid to push the telescopic sleeve 221 to extend until the movable section of the telescopic sleeve 221 abuts against the limiting block 33, thereby locking the tooling table 3 and reducing the displacement of the tooling table 3 and even the plate material fixed above it during the cutting process.

[0114] In another embodiment of this system, the vacuum adsorption hole 42 of the aforementioned platform 41 is not always evacuated. Instead, it can be configured such that the controller 8 determines the position of the adsorption plate 11 based on the movement of the linear driver 12, and controls the vacuum adsorption hole 42 located below the adsorption plate 11 to evacuate based on the position of the adsorption plate 11.

[0115] Regarding whether the vacuum adsorption hole 42 is used to draw a vacuum tube, that is, whether the valve on its corresponding pipe is open.

[0116] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
